[0021] A method for gear production and processing, comprising the following steps;

[0022] S1: Through the filtering mechanism, using the filter in the filtering part, the garbage first falls into the filter. At this time, the waterproof motor starts, which drives the rotating rod to rotate. The rotation of the rotating rod further drives the cam to rotate. Since the cam and the filter are adapted to each other, the rotation of the cam causes the filter to slide along the surface of the slide rail under the support of the slide seat. This sliding action causes the filter to shake. The shaking of the filter helps to shake out the liquid attached to it, while the solid garbage flows into the collection box below through the screening effect of the filter. In this process, large particles of impurities and suspended solid impurities are effectively removed;

[0023] S2: Through the adsorption mechanism, using the adsorption box in the adsorption part, first, the seepage source liquid treated by the filtering mechanism is introduced into the adsorption box in the adsorption part through the drain pipe. In the adsorption box, the seepage source liquid flows through the adsorption plate, which is designed to adsorb fine impurities in the seepage source liquid. The purity of the seepage source liquid after adsorption treatment by the adsorption plate is further improved, and then it enters the purification mechanism for further purification treatment. After a long period of operation, the adsorption plate may be blocked due to the adsorption of a large amount of impurities. The operator can pull the pull plate, which is connected to the adsorption box. By pulling the pull plate, the adsorption box can be tested. Then, the operator turns the bolt, which is originally used to clamp the adsorption plate so that it can be stably installed in the slide slot. By turning the bolt, the clamping effect on the adsorption plate can be released, so that the adsorption plate can be pulled out from the inner side of the slide slot. Once the adsorption plate is pulled out, the operator can clean it to remove the impurities adsorbed on it. After cleaning, the adsorption plate is put back into the slide slot and clamped with bolts for continued use;

[0024] S3: Through the purification mechanism, using the connecting pipe in the purification part, first, the seepage source liquid that has been adsorbed is introduced into the purification box through the connecting pipe, and then the water pump is started. The pump extracts the purified liquid from the inner wall of the purified water tank. The purified liquid is transported to the branch pipe through the water supply pipe and finally sprayed out from the nozzle to purify the seepage source liquid in the purification box. During the purification process, the motor is turned on. The rotation of the motor drives the light rod and the stirring blade to rotate together. This stirring action causes the seepage source liquid to be fully mixed with the purified liquid sprayed from the nozzle in the purification box. Through this mixing, harmful substances such as salts, bacteria, viruses, ions, toxic organic matter, etc. in the seepage source liquid can be effectively removed.

[0025] Compared with the prior art, the invention has the following beneficial effects: the garbage leachate pretreatment device and method,

[0026] 1) Through the filtering mechanism, the filter net in the filter part is used, so that the garbage falls into the filter net, and through the waterproof motor, the waterproof motor drives the rotating rod. The rotating rod drives the cam, so that the cam and the filter net are adapted to each other, so that the filter net slides on the surface of the slide rail under the action of the slide seat, so that the filter net is shaken, so that the liquid therein is shaken out, so that the solid flows into the collection box through the filter net, and the large particles and suspended solid impurities therein, such as branches, plastic bags, stones, etc., are removed to prevent these impurities from clogging the subsequent processing equipment;

[0027] 2) Through the adsorption mechanism, using the adsorption box in the adsorption part, the filtered seepage source liquid enters the adsorption box through the drain pipe, and then is adsorbed by the adsorption plate, and then enters the purification mechanism after adsorption. When the adsorption plate is blocked, the pull plate is pulled, so that the pull plate drives the adsorption box, and then the bolt is rotated, so that the bolt releases the clamping of the adsorption plate, so that the adsorption plate is pulled away from the inner side of the chute for cleaning, so that the filtered seepage source liquid can further adsorb fine impurities;

[0028] 3) Through the purification mechanism, using the connecting pipe in the purification part, the adsorbed seepage source liquid enters the purification box through the connecting pipe, thereby starting the water pump, so that the water pump extracts the purified liquid from the inner wall of the purification tank, and then enters the branch pipe through the water supply pipe and is sprayed out from the nozzle for purification. At the same time, the motor is turned on to drive the polished rod and the stirring blade to rotate, so that the seepage source liquid and the purified liquid are fully mixed, which can remove harmful substances such as salts, bacteria, viruses, ions, toxic organic matter in the water, thereby achieving a good purification effect.

During the purification process, the motor 423 is turned on. The rotation of the motor 423 drives the light rod 424 and the stirring blades to rotate together.

10. A method for gear production and processing according to any one of claims 1 to 9, characterized in that: The steps include: S1: Through the filtering mechanism (2), using the filter screen (215) in the filtering part (21), the garbage first falls into the filter screen (215). At this time, the waterproof motor (212) is started, which drives the rotating rod (213) to rotate. The rotation of the rotating rod (213) further drives the cam (214) to rotate. Since the cam (214) and the filter screen (215) are adapted to each other, the rotation of the cam (214) causes the filter screen (215) to slide along the surface of the slide rail (222) under the support of the slide seat (221). This sliding action causes the filter screen (215) to shake. The shaking of the filter screen (215) helps to shake out the liquid attached to it, while the solid garbage flows into the collection box (225) below through the screening effect of the filter screen (215). In this process, large particle impurities and suspended solid impurities are effectively removed; S2: Through the adsorption mechanism (3), using the adsorption box (311) in the adsorption part (31), first, the seepage source liquid treated by the filtering mechanism (2) is introduced into the adsorption box (311) in the adsorption part (31) through the drain pipe. In the adsorption box (311), the seepage source liquid flows through the adsorption plate (321). The adsorption plate (321) is designed to adsorb fine impurities in the seepage source liquid. After the adsorption treatment by the adsorption plate (321), the purity of the seepage source liquid is further improved. Then, the seepage source liquid enters the purification mechanism (4) for further purification treatment. After a long period of operation, the adsorption plate (321) may be blocked due to the adsorption of a large amount of impurities. The operator can pull the pull plate (313) and the pull plate (313) and the adsorption plate (313) are connected to the adsorption box (4). The suction box (311) is connected to the suction box (311). By pulling the pull plate (313), the suction box (311) can be opened. Then, the operator rotates the bolt (323). The bolt (323) is originally used to clamp the suction plate (321) so that it can be stably installed in the slide groove (322). By rotating the bolt (323), the clamping effect on the suction plate (321) can be released, so that the suction plate (321) can be pulled out from the inner side of the slide groove (322). Once the suction plate (321) is pulled out, the operator can clean it to remove the impurities adsorbed on it. After cleaning, the suction plate (321) is put back into the slide groove (322) and clamped and fixed with the bolt (323) for continued use. S3: Through the purification mechanism (4), using the connecting pipe (413) in the purification part (41), first, the seepage source liquid that has been adsorbed is introduced into the purification box (411) through the connecting pipe (413), and then the water pump (415) is started. The pump extracts the purified liquid from the inner wall of the purified water tank (414). The purified liquid is transported to the branch pipe (422) through the water supply pipe (421) and finally sprayed out from the nozzle to purify the seepage source liquid in the purification box (411). During the purification process, the motor (423) is turned on. The rotation of the motor (423) drives the light rod (424) and the stirring blade to rotate together. This stirring action causes the seepage source liquid and the purified liquid sprayed from the nozzle to be fully mixed in the purification box (411). Through this mixing, harmful substances such as salts, bacteria, viruses, ions, toxic organic matter, etc. in the seepage source liquid can be effectively removed.
