The present invention relates to a pumping device for suction pumping sludge together with wastewater and sewage in various wastewater storage tanks or sewage tanks. More specifically, the present invention relates to some wastewater and sewage pumped from a pump. By spraying the sludge precipitated at high pressure into the crushed sludge, the sludge deposited at the bottom of the storage tank or the sewage tank is easily sucked and removed, and the solids are crushed and cut at the high speed rotating impeller and the suction port, so that the pump is damaged. It relates to a sludge pumping device that effectively prevents and increases the pumping force.

In general, livestock manure and sewage from the livestock industry and various wastewater and sewage are first introduced into separate reservoirs or sewage tanks and then composted to liquid fertilization through microbial fermentation or discharged to rivers through biochemical purification processes. It is used for living water.

The high concentration of livestock manure, sewage, and various wastewater and sewage contain a large amount of solids or various foreign substances, so that a large amount of sludge is settled at the bottom of a storage tank or a sewage tank, and when such sludge is left as it is. Since the utility space of the storage tank or sewage tank is gradually reduced, it is more preferable to recover and process it.

Conventional Utility Model Registration No. 20-0195722 (organic waste crushing device) has been proposed as a method for effectively removing sludge deposited in a storage tank or a sewage tank into which livestock manure and sewage of high concentration are introduced. Part of the manure or sewage that is pimped from is sprayed on the sludge settled on the floor to grind the sludge to remove the pumping method.

Looking at the structure of the organic waste crusher proposed in the prior art as described above, a flange for pumping manure or sewage discharged on one side of the casing of the pump is provided, the T-shaped tube is coupled to the flange while the The discharge hose is coupled to one open side, and the other side is provided with a lid to adjust the size of the hole.

Therefore, when manure or sewage is pumped by the high speed rotation of the impeller in the casing, some of them are pumped from the T-shaped tube to the desired place through the discharge hose, and some are settled through the holes in the lid installed on one side of the T-shaped tube. The sludge is injected into the sludge to be crushed.

However, such a conventional structure is a situation in which the precipitated sludge is not effectively pulverized as the manure or sewage sprayed at a high pressure to pulverize the precipitated sludge is injected only from the hole of the lid installed on one side of the T-shaped tube. Since manure or sewage is injected only in the hole to crush sludge, the area is limited, and thus, the sludge that is deposited cannot be effectively removed.

The prior art in the above can adjust the injection amount and the pumping amount by adjusting the hole of the lid, but even if the amplification of the injection can not expect a great effect, and if the amplification of the injection amount is excessively reduced the pumping amount, effectively crush the precipitated sludge There was a problem that could not be removed.

The present invention has been made in order to solve the problems according to the prior art as described above, by extensively crushing the sludge deposited on the bottom of the storage tank or sewage tank in which livestock waste and waste water flows to remove the sludge effectively suction pumping and high speed It is a main object of the present invention to provide a sludge pumping device that effectively prevents damage to a pump and increases pumping power by crushing and cutting solid materials at a rotating impeller and a suction port.
