[0015] The principles and advantages of this solution are: 1. In this solution, the waste liquid is collected to the bottom of the inner box through the filter, and the impurities in the waste liquid can be filtered out through the filter; then the neutralizing drug is introduced into the inner box, so that the waste liquid and the neutralizing drug are mixed and purified in the inner box; compared with the existing technology, the horizontal block is used to drive the brush layer to move back and forth horizontally, and the filter is cleaned by the brush layer to avoid clogging of the filter.

[0016] 2. The bristle layer of this solution can move back and forth horizontally, and then the filter can be cleaned by the bristle layer to prevent the filter from being blocked; moreover, the bristle layer can also move back and forth vertically, so that the bristle layer can penetrate the filter and lift up the debris on the filter, turning over the debris, thereby preventing the debris from blocking or clogging the filter, ensuring the smooth flow of the filter, that is, ensuring that the waste liquid can continue to pass through the filter.

[0017] 3. During the rotation of the shaft of this scheme, the shaft drives the piston block to reciprocate in the piston cylinder through the first cylindrical cam, the first curved groove, the first auxiliary block, and the movable block, so that the neutralizer in the liquid medicine box can be introduced into the inner box through the liquid inlet pipe, the piston cylinder, and the liquid outlet pipe; during the rotation of the shaft, the shaft drives the stirring arm to rotate through the worm, the worm gear, and the circular shaft, and the stirring arm is used to mix the waste liquid and the neutralizer in the inner box to accelerate the purification of the waste liquid; therefore, during the rotation of the shaft, the neutralizer can be introduced into the inner box, and the waste liquid and the neutralizer in the inner box can also be mixed and purified, which is highly practical.

[0018] 4. During the horizontal reciprocating motion of the movable block of this scheme, it can simultaneously drive the two piston blocks to move horizontally and reciprocatingly, thereby enabling the neutralizing medicine in the medicine liquid tank to be introduced into the two inner boxes respectively, and at the same time realize the purification of the waste liquid in the two inner boxes, thereby improving the purification efficiency of the waste liquid.

[0019] 5. In this solution, during the rotation of the circular shaft, the circular shaft drives the stirring arm to mix the waste liquid and neutralizing drug in the inner box; during the rotation of the circular shaft, the circular shaft also drives the cam body to rotate, and the cam body drives the transverse block to move back and forth horizontally through the wall groove, and the transverse block drives the bottom block to move synchronously, so that the bottom block can intermittently squeeze the swing arm, causing the torsion spring to deform, and then the swing arm can swing back and forth left and right, so that the waste liquid and neutralizing drug on both sides of the circular shaft can be stirred, promoting the mixing and purification of the two, and expanding the mixing and purification range; therefore, this solution can carry out mixed purification treatment of waste liquid and neutralizing drug in two ways, thereby enhancing the purification effect and improving the purification efficiency.

[0020] 6. During the rotation of the circular shaft of this scheme, the circular shaft can drive the stirring arm to rotate for mixing work. The circular shaft can also make the swing arm swing back and forth to mix work through the cam body, transverse block, bottom block, swing arm, and torsion spring. The circular shaft can also drive the supporting block and the brush layer to reciprocate vertically through the second cylindrical cam, the second auxiliary block, the lifting block, the linkage block, the linkage groove, and the side block. In this way, the brush layer is used to pass through the filter screen to clean the filter screen. At the same time, it can also lift up the debris on the filter screen and turn over the debris to avoid the debris blocking or clogging the filter screen. Therefore, during the rotation of the circular shaft, the waste liquid and the neutralizer can be mixed and the filter screen can be cleaned, which is highly practical.

The waste liquid is collected to the bottom of the inner box 20 through the filter screen 23, so that the debris is filtered on the surface of the partition 22.

[0031] Start the motor 43, and the output shaft of the motor 43 drives the driving gear 44 to rotate. The driving gear 44 engages with the driven gear 45 to drive the rotating shaft 40 to rotate. The rotating shaft 40 drives the first cylindrical cam 41 to rotate. The first cylindrical cam 41 drives the movable block 32 to reciprocate laterally through the first curved groove and the first auxiliary block 42.

[0034] During the lateral reciprocating motion of the lateral block 51, the lateral block 51 drives the bottom block 74 to move lateral reciprocatingly, so that the bottom block 74 intermittently squeezes the swing arm 73. When the bottom block 74 squeezes the swing arm 73, the swing arm 73 and the side shaft 72 swing synchronously, and the torsion spring deforms; when the bottom block 74 moves away from the swing arm 73, the swing arm 73 and the side shaft 72 swing in opposite directions under the action of the torsion spring; therefore, the swing arm 73 can swing left and right, thereby stirring the waste liquid and the neutralizing drug on both sides of the circular shaft 50, promoting the mixing and purification of the two, expanding the mixing and purification range, enhancing the purification effect, and improving the purification efficiency.

[0035] During the rotation of the circular shaft 50, the transverse block 51 reciprocates laterally, and the transverse block 51 drives the supporting block 60 to reciprocate laterally, and the supporting block 60 drives the side block 64 to move synchronously, so that the side block 64 moves laterally in the linkage groove 68; during the rotation of the circular shaft 50, the circular shaft 50 also drives the second cylindrical cam 63 to rotate, and the second cylindrical cam 63 drives the linkage block 67 to reciprocate vertically through the second curved groove, the second auxiliary block 65, and the lifting block 66.
