The rotary kiln is main equipment of a cement clinker production line, when the rotary kiln system has operation faults, positive pressure of the decomposing furnace can cause tempering, garbage combustibles are treated after municipal solid waste is cooperatively treated, and serious potential safety hazards exist; the general technological process of the upper part of the prior combustible material system preheater is as follows: the material is carried to the flat belt through the inclined belt and then to a square three-way air locking valve, then enters a single-tube sealing reamer, is carried into the interior of a preheater decomposing furnace, if the outage of a whole factory leads to insufficient air supply pressure, the valve plate can not be closed in place or the air cylinder can not push the valve plate, a fire source and combustible materials can not be completely isolated, the fire can flow along the combustible materials to the single-tube reamer, and a blanking slider is arranged until the inclined belt, so that the inclined belt of the combustible materials is burnt out, equipment accidents are caused, and the safe operation of a combustible material system is seriously influenced.
Disclosure of Invention
The invention provides an anti-backfire cement rotary kiln device, which can effectively avoid accidents caused by fault backfire of a rotary kiln system by modifying a locking air valve.
In order to achieve the above purpose, the invention adopts the following technical scheme:
an anti-backfire rotary cement kiln apparatus comprising: the inclined belt head is connected with one end of a flat belt scale, the other end of the flat belt scale is connected with one end of a single-tube sealing reamer through a slide, the other end of the single-tube sealing reamer is connected with a wind locking valve, the other end of the wind locking valve is connected with a decomposing furnace, a section of the middle part of the slide is cut off, two sections of flanges are arranged on the upper section and the lower section of the slide, the flanges are respectively connected with a pneumatic valve plate, an air storage tank is additionally arranged near the pneumatic valve plate, the air storage tank is connected with the pneumatic valve plate through an air outlet pipeline, and a one-way valve is connected to an air inlet pipeline of the air storage tank.
In the structure, the single-tube sealing reamer is connected with the air locking valve through the flange plate bolt, the air locking valve is a single-plate air locking device, the air locking valve plate is arranged inside the single-plate air locking device, two valve arms are arranged outside the single-plate air locking device, a counterweight is added on the valve arms according to the internal air locking effect, when combustible garbage is conveyed to the air locking valve plate, the air locking valve plate is opened for discharging, and the air locking valve is welded with the decomposing furnace shell into a whole.
The beneficial effects are that: the invention provides an anti-backfire cement rotary kiln device, which is characterized in that square three air locking valves in the original device are removed to be changed into a slide carriage, two square pneumatic valve plates are arranged on the slide carriage, once a rotary kiln process accident happens, a central control operator immediately closes the two valve plates to isolate combustible materials and fire sources, the condition that the valve plates are not closed in place or an air cylinder cannot push the valve plates due to insufficient air supply pressure caused by power failure of a whole plant is considered, the fire sources and the combustible materials cannot be completely isolated, an air storage tank is additionally arranged near the pneumatic valve plates by a company, and a one-way valve is additionally arranged on an air inlet pipeline to ensure that compressed air only cannot enter or exit. Therefore, even if the gas is cut off or trips, the two valve plates can be closed by compressed air in the gas storage tank in time to ensure complete isolation of complete combustibles and fire sources, and in addition, in order to reduce the air leakage rate of the system and prevent tempering, a company adds a set of air locking valve at the joint of the head of the single-tube sealing reamer for combustibles and the decomposing furnace. The accident caused by the fault tempering of the rotary kiln system is effectively controlled through the transformation, and the air leakage of the system is reduced.
Drawings
FIG. 1 is a schematic diagram of a conventional apparatus;
FIG. 2 is a schematic view of the apparatus of the present invention.
Detailed Description
The invention is described in detail below with reference to the attached drawings and the specific embodiments:
an anti-backfire rotary cement kiln apparatus comprising: the inclined belt head is connected with one end of a flat belt scale, the other end of the flat belt scale is connected with one end of a single-tube sealing reamer through a slide, the other end of the single-tube sealing reamer is connected with a wind locking valve, the other end of the wind locking valve is connected with a decomposing furnace, a section of the middle part of the slide is cut off, two sections of flanges are arranged on the upper section and the lower section of the slide, the flanges are respectively connected with a pneumatic valve plate, an air storage tank is additionally arranged near the pneumatic valve plate, the air storage tank is connected with the pneumatic valve plate through an air outlet pipeline, and a one-way valve is connected to an air inlet pipeline of the air storage tank.
In the structure, the single-tube sealing reamer is connected with the air locking valve through the flange plate bolt, the air locking valve is a single-plate air locking device, an air locking valve plate is arranged inside the single-plate air locking device, two valve arms are arranged outside the single-plate air locking device, a counterweight is added on the valve arms according to the internal air locking effect, the air locking effect is guaranteed, the single-tube sealing reamer is in a closed state under normal conditions, when combustible garbage is conveyed to the air locking valve plate through the sealing reamer, the material is ejected from the valve plate through the sealing reamer thrust to overcome the self weight of the valve plate and the resistance of the external valve arms and the counterweight, and the air locking valve is welded with a decomposing furnace shell into a whole.
Through improving traditional device, demolish square three-way air locking valve and become the swift current son to install two square pneumatic valve plates on the swift current son, in case take place rotary kiln technology accident immediately by well accuse operator close two valve plates, isolated combustible material and fire source, can lead to the valve plate to close not in place or the cylinder can't promote the valve plate when considering the outage of whole factory leads to air feed pressure inadequately, can't keep apart fire source and combustible material completely, the company increases a gas holder near pneumatic valve plate, and increases a check valve on the admission line and ensure that compressed air only does not get in and out. Therefore, even if the gas is cut off or trips, the two valve plates can be closed by compressed air in the gas storage tank in time to ensure complete isolation of complete combustibles and fire sources, and in addition, in order to reduce the air leakage rate of the system and prevent tempering, a company adds a set of air locking valve at the joint of the head of the single-tube sealing reamer for combustibles and the decomposing furnace. The accident caused by the fault tempering of the rotary kiln system is effectively controlled through the transformation, and the air leakage of the system is reduced.
