Detailed ways

The utility model, as shown in Figure 1-7, comprises a stirring tank 1, a screen 2 and a collecting hopper 4, the collecting hopper 4 is located at the lower part of the stirring tank 1, and a mixing tank 1 and a collecting hopper 4 are arranged There is a horizontally arranged suction slot 32, the suction slot 32 runs through the stirring tank 1, and the first and second suction sockets are reserved on the stirring tank 1, and guide rails are arranged outside the first suction socket Section one 31, is provided with guide rail section two 33 outside drawing out socket two; In described drawing out slot 32, be provided with check groove guide rail section 321; Described guide rail section one 31, guide rail section two 33 and draw out slot guide rail section 321 is the overall guide rail 3;

Described screen cloth 2 is square, and four sides are provided with screen cloth frame 21, is used for fixing filter cloth 22; Described screen cloth 2 has two pieces, and end-to-end ground is flexibly connected on the described integral guide rail 3; The described screen cloth The front and rear sides of the frame 21 are chamfered (as shown in Figure 5-6), which matches the shape of the guide rail section 321 of the draw slot, and plays a guiding role during the movement. The height of the screen frame 21 is greater than the draw and insert The distance between the upper and lower inner planes of the groove rail section 321 is to ensure the sealing of the front and rear sides of the screen 2 and prevent the paint from overflowing; the length of the filter 22 ≥ the internal length of the mixing tank 1, The mesh number is determined according to the particle diameter of different coatings.

Both sides of the bottom of the stirring tank 1 are provided with tank body sealing strips 11, the length of the tank body sealing strip 11 is greater than the width of the filter screen 22, and is ≤ the distance a between the integral guide rails 3; the tank body The thickness of the sealing strip 11 is greater than the distance b from the bottom of the stirring tank 1 to the upper plane of the screen frame 21 , so as to ensure the sealing of both sides of the screen 1 when it is in operation.

The collecting hopper 4 is in the shape of a square funnel, and the length and width of the mouth are greater than the length and width of the filter screen 22 respectively.

It also includes a conveying pipe 5, a flow monitor 6 and a cleaner 7, the conveying pipe 5 is sealingly connected to the discharge port of the collecting hopper 4, and the flow monitor 6 is arranged on the conveying pipe 5 for monitoring The flow rate of the filtered paint can send an alarm to the screen 2 that needs to be cleaned.
