DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1-Figure 6A chemical wastewater filtering device is shown, comprising a box body 100, a cover plate 200 and a filter assembly 300, wherein the flange of the cover plate 200 is assembled on the top of the box body 100, the filter assembly 300 is erected in the box body 100 along an inclined direction, a flushing pipeline 400 and a slag discharge assembly 500 are respectively provided on the left and right sides of the box body 100, a wastewater pipeline 600 connected to the box body 100 is provided on the top of the cover plate 200, the slag discharge assembly 500 comprises a discharge pipe 510 and an intercepting gate plate 520 erected in the discharge pipe 510, a cover shell 530 connected to the discharge pipe 510 is provided on the top of the discharge pipe 510, a cylinder 540 distributed in a vertical direction is fixedly installed on the top of the cover shell 530, and an output end of the cylinder 540 passes through the cover shell 530 and is fixedly connected to the top of the gate plate 520.

[0021] Based on the arrangement of the above structure, specifically, during the working process, chemical wastewater is input into the treatment chamber composed of the box body 100 and the cover plate 200 through the wastewater pipe 600. When the wastewater falls through the filter assembly 300, the filtration is completed and finally discharged from the output end at the bottom of the box body 100. After the filtration work is completed or when the filter assembly 300 needs to be cleaned regularly, the operator first closes the wastewater pipe 600, and opens the flushing pipe 400 and the slag discharge assembly 500. The flushing pipe 400 starts to supply water from the side of the box body 100. Since the filter assembly 300 is tilted, the supplied water flow can be flushed along the upper surface of the filter assembly 300. The slag discharge assembly 500 is extended by the output end of the cylinder 540. The contraction can drive the gate plate 520 to rise and fall, thereby realizing the opening and closing of the discharge pipe 510. The impurities accumulated on the surface of the filter component 300 are finally discharged from the slag discharge component 500 along with the water flow, thereby completing the disassembly-free cleaning operation. The chemical wastewater filtering device is provided with a flushing pipeline 400 and a slag discharge component 500 on both sides of the box body 100, and is configured with a filter component 300 erected in an inclined direction. Water is supplied to one side of the flushing pipeline 400, and the slag discharge component 500 is drained. Under the guidance of the inclined filter component 300, the impurities accumulated on the upper surface of the filter component 300 can be discharged through the slag discharge component 500, so that the filter medium 310 can be cleaned efficiently and quickly, and at the same time, cumbersome disassembly and assembly actions can be avoided.

[0022] Furthermore, the filter assembly 300 includes a filter medium 310 and a mounting baffle 320 respectively disposed on the inner side and the outer side of the housing 100, a handle 330 is fixedly mounted on the outer side of the mounting baffle 320, two mutually parallel fixing bars 340 are disposed on the inner side of the mounting baffle 320, and a mounting gap is reserved between the two fixing bars 340 for the edge of the filter medium 310 to be embedded. Specifically, during the disassembly process, after unscrewing the screws on the mounting baffle 320, the operator can pull out the entire filter assembly 300 with the help of the handle 330, and then for the removed filter assembly 300, the operator removes the filter medium 310 embedded between the two fixing bars 340, so that the filter medium 310 can be replaced.

[0023] Furthermore, a sealing ring 350 is provided between the mounting baffle 320 and the housing 100, and the sealing ring 350 is sleeved on the outside of the two fixing strips 340. Specifically, during the installation process, the operator first sleeves the sealing ring 350 on the outside of the two fixing strips 340, then the operator inserts the filter medium 310 between the two fixing strips 340 and locks and fixes it, and finally the operator inserts the entire filter assembly 300 into the housing 100, and tightens the four screws that penetrate the mounting baffle 320 in sequence, thereby achieving the fixed insertion of the filter assembly 300 on the housing 100, at which time, the sealing ring 350 is provided between the mounting baffle 320 and the housing 100.

[0024] Furthermore, the flushing pipeline 400 includes a circulating water main pipe 410 and a plurality of water distribution branches 420, and the axes of the plurality of water distribution branches 420 are all in the same plane and the plane is parallel to the filter assembly 300. Specifically, during use, one end of the circulating water main pipe 410 is blocked, and the other end can be connected to the municipal water network or directly connected to the treated chemical wastewater storage equipment. For example, after the chemical wastewater is filtered, it is output from the output end at the bottom of the box 100, or connected to a storage tank or to a subsequent treatment equipment. The circulating water main pipe 410 can introduce filtered water flow or introduce water flow that has completed subsequent treatment, thereby realizing the reuse of chemical wastewater and effectively reducing production costs.

[0025] Furthermore, guide bars 550 extending vertically downward are provided on both inner side walls of the cover 530, and limiting grooves 560 matching the guide bars 550 are provided on both side walls of the gate 520. Specifically, the two guide bars 550 extend to the inner bottom wall of the discharge pipe 510. On the one hand, the guide bars 550 cooperate with the limiting grooves 560 to ensure the stability of the gate 520 in lifting and lowering. On the other hand, the two guide bars 550 integrally installed with the cover 530 extend into the discharge pipe 510 and are fixedly installed, ensuring that the cover 530 is assembled on the discharge pipe 510 securely and firmly.

[0026] Furthermore, the wastewater pipeline 600 includes a wastewater inlet main pipe 610, a first branch pipe 620 and a second branch pipe 630. The first branch pipe 620 and the second branch pipe 630 are both vertically welded to the bottom of the wastewater inlet main pipe 610. A partition 700 distributed in a vertical direction is installed inside the box body 100 and above the filter assembly 300. The first branch pipe 620 and the second branch pipe 630 are respectively arranged on both sides of the partition 700. Specifically, the wastewater pipeline 600 includes a wastewater inlet main pipe 610, a first diversion pipe 620 and a second diversion pipe 630. Preferably, a partition 700 is installed in the box body 100 to separate the first diversion pipe 620 and the second diversion pipe 630, so that the box body 100 is divided into dual channels. After solenoid valves are respectively installed on the first diversion pipe 620 and the second diversion pipe 630 for alternating control, the filter assembly 300 can be used alternately in different areas, thereby improving the utilization rate of the filter assembly 300.
