Description
技术领域technical field
本发明涉及喷涂设备粉末回收设备领域，具体涉及一种静电喷涂设备粉末智能高效回收系统装置。The invention relates to the field of powder recovery equipment for spraying equipment, in particular to an intelligent and efficient recovery system device for electrostatic spraying equipment powder.
背景技术Background technique
静电喷涂是利用高压静电电场使带负电的涂料微粒沿着电场相反的方向定向运动，并将涂料微粒吸附在工件表面的一种喷涂方法。基本原理为在喷枪与工件之间形成一个高压电晕放电电场，当粉末粒子由喷枪口喷出经过放电区时，便补集了大量的电子，成为带负电的微粒，在静电吸引的作用下，被吸附到带正电荷的工件上去。当粉末附着到一定厚度时，则会发生“同性相斥”的作用，不能再吸附粉末，从而使各部分的粉层厚度均匀，然后经加温烘烤固化后粉层流平成为均匀的膜层。粉末静电喷涂设备主要包括：喷粉室、高压静电发生器、静电喷涂枪、供粉器、粉末回收装置、工件旋转机构。目前的粉末回收装置结构为例如201410072576.9 公开了一种粉末回收装置，其特征在于，包括，用于吸取粉末的吸取机构；旋风送料器，该旋风送料器包括内置的引风机构、连接于引风机构进风端并与吸取机构连通的进风口、连接于引风机构出风端的出风口；粉末分离仓，该粉末分离仓包括一个呈倒“U”形的分离通道、以及分别位于分离通道两端的粉末进口和粉末出口，粉末进口与出风口连通；料仓，该料仓包括壳体、以及封盖在壳体顶端部的仓盖，料仓内部设置有一位于仓盖下方的格栅，仓盖上设置有一位于格栅上方且与粉末出口连通的进料口。这种结构的粉末回收装置均为通过风机的吸入，然后直接进行回收，这样直接回收的粉末中参杂着空气中的灰尘，使回收的粉末纯度不够，容易使二次加工的质量下降。Electrostatic spraying is a spraying method that uses a high-voltage electrostatic electric field to make negatively charged paint particles move in the direction opposite to the electric field, and adsorb the paint particles on the surface of the workpiece. The basic principle is to form a high-voltage corona discharge electric field between the spray gun and the workpiece. When the powder particles are ejected from the spray gun mouth and pass through the discharge area, a large number of electrons will be collected and become negatively charged particles. Next, it is adsorbed to the positively charged workpiece. When the powder adheres to a certain thickness, the effect of "same sex repulsion" will occur, and the powder can no longer be adsorbed, so that the thickness of the powder layer in each part will be uniform, and then the powder layer will be leveled and become a uniform film after heating, baking and curing. Floor. Powder electrostatic spraying equipment mainly includes: powder spraying room, high-voltage electrostatic generator, electrostatic spraying gun, powder supply device, powder recovery device, and workpiece rotating mechanism. The structure of the current powder recovery device is, for example, 201410072576.9, which discloses a powder recovery device, which is characterized in that it includes a suction mechanism for sucking powder; The air inlet end of the mechanism and the air inlet connected to the suction mechanism, the air outlet connected to the air outlet end of the air induction mechanism; the powder separation chamber, the powder separation chamber includes an inverted "U"-shaped separation channel, and the two sides of the separation channel are respectively The powder inlet and powder outlet at the end, the powder inlet and the air outlet are connected; the silo, the silo includes a shell, and a cover on the top of the shell. The cover is provided with a feeding port which is located above the grid and communicates with the powder outlet. The powder recovery device of this structure is inhaled by the fan, and then directly recovers, so that the directly recovered powder is mixed with dust in the air, which makes the recovered powder not pure enough, and easily reduces the quality of secondary processing.
