Description of the drawings:
FIG. 1 is a schematic structural view of the slag-making system for the waste paint in the paint spray booth.
Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be clearly and clearly defined.
As shown in fig. 1, a paint spray booth waste paint slagging system comprises a flume 1, a liquid collecting tank 5, a water outlet tank 6 and a collecting tank 11, wherein the flume 1 is arranged at the top end of the liquid collecting tank 5, the inner cavity of the flume 1 is communicated with the inner cavity of the liquid collecting tank 5 through a guide plate 3, the guide plate 3 extends to the bottom end of the liquid collecting tank 5, a water inlet nozzle 4 capable of spraying liquid upwards is arranged at the bottom end of the guide plate 3, a flow baffle plate 13 is arranged at one side of the liquid collecting tank 5 close to the water outlet tank 6, the flow baffle plate 13 separates the liquid collecting tank 5 into a U-shaped water outlet channel with an opening at the bottom, the water outlet tank 6 is arranged at the left side of the liquid collecting tank 5, the top end of the water outlet tank 6 is communicated with the top end of the liquid collecting tank 5, a height-adjustable overflow weir 7 is arranged at the communication position of the top end of, the top end of the collecting groove 11 is communicated with the top end of the liquid collecting groove 5 through a static area 10 inclined leftwards and downwards, and an overflow weir 12 is arranged at the communication position of the collecting groove 11 and the top end of the static area 10.
The backwater of the spray booth containing the waste paint slag particles is pumped into the launder 1 by a water pump and then passes through a water flow descender 2 which flows downwards. The water inlet of the water flow descender 2 is provided with a circular guide plate 3, so that the speed direction of the water flow can be changed from the horizontal direction to the vertical direction. This change in direction causes the water flow to create turbulence at the inlet of the descender to prevent build-up of paint residue there. The descenders are designed with different dimensions depending on the treatment capacity to ensure that paint residues suspended on the water surface in the running water tank can flow downwards and can pass through the water inlet nozzle 4 with the adjusting plate. The shape of the water inlet nozzle 4 and the design of the baffle plate can prevent paint slag from forming large-area accumulation at the bottom and enable water flow to uniformly pass through the liquid collecting tank 5. The upward speed of the water flow is controlled by the adjusting plate of the water inlet nozzle 4 to become slower, so that paint slag particles are easy to float and agglomerate on the liquid surface of the liquid collecting tank, and a raft-shaped paint slag layer is formed on the water surface when flocculent paint slag is more and more gathered.
The upward jet water flow carrying paint slag enters the liquid collecting tank 5, and the movement is accompanied with the attachment and floating of paint slag particles by tiny bubbles generated when the water flow is jetted by the water inlet nozzle 4. The height of the sump 5 is designed so that the "raft-like" layer of paint residue that has formed on the surface is not destroyed by the flow of water from the bottom.
The clear water from which the paint residues are removed then flows out from the bottom along the flow baffle 13 in the liquid collection tank 5 into the effluent tank 6. The sump 5 is dimensioned such that the rate of fall of the water is less than the natural rate of rise of the paint slag particles.
The water flows to the outlet tank 6 and then over the weir 7. The overflow weir 7 is designed to be adjustable and has the main function of controlling the height of the working liquid level in the liquid collecting tank 5 and further controlling the height of the working liquid level of the water flow descender.
The water outlet 8 of the slagging unit is provided with a pneumatic transfer valve 9 controlled by an electromagnetic valve. This valve will close automatically when the slag layer needs to be removed at regular intervals. When the flow is finished, the valve will automatically open to return to the initial position.
A quiescent zone 10 and a collection trough 11 are located at the other end of the sump 5. The quiescent zone 10 is a shallow conical trough intermediate the collection trough 11 and the collection trough 10. The aim is to cause the friable paint slag particles to agglomerate and float successfully in a quiet zone, thus avoiding any residual turbulence in the sump caused by the jet from the water inlet nozzle. The location of the small baffles in the water inlet nozzle may promote the flow of paint slag particles into the quiescent zone 10.
At the end of the quiescent zone 10 near the collection trough 11 is mounted a weir 12.
When transfer valve 9 closed, the liquid level in the collecting tank 10 risees, and "valve form" lacquer sediment layer that forms on the collecting tank 10 surface of water gets into to collecting tank 11 along with the direction of rivers in, installs the braided bag of taking the micropore in collecting tank 11, and the clear water can be reserved through the micropore and return to in the paint spray booth, and the interior woven bag is reserved to the lacquer sediment of condensing.
Through the system, paint slag particles in the circulating water of the paint spraying chamber can be effectively removed, and clear water returns to the paint spraying chamber for recycling.
