Abstract
Description
Technical Field
[0001] This utility model relates to the field of municipal solid waste leachate treatment technology, specifically a municipal solid waste leachate collection and treatment device. Background Technology
[0002] Household waste contains a lot of liquid waste. When collecting and processing this waste, the water needs to be squeezed out to separate the solid waste from the water (leachate). In order to avoid the direct discharge of the separated water (leachate) and causing pollution to the environment, it needs to be treated by a household waste leachate collection and treatment device.
[0003] In practical use, existing municipal solid waste leachate treatment devices rely mainly on filters to separate solid impurities from the leachate. To ensure the normal operation of the device, staff need to clean the filters regularly, which is quite troublesome. Therefore, in order to address the above problems, a municipal solid waste leachate collection and treatment device is designed to better meet practical needs. Utility Model Content
[0004] The purpose of this invention is to provide a device for collecting and treating leachate from municipal solid waste, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a municipal solid waste leachate collection and treatment device, comprising a treatment tank and a motor. The motor is fixed to the rear end face of the treatment tank, and a rotating shaft is fixed to the output end of the motor. The rotating shaft is bearing-connected inside the treatment tank, and a filter screen is fixed on the rotating shaft. The filter screen slides in contact with a collection hopper, which is fixed inside the treatment tank. A scraper is fixed on the collection hopper, and the scraper slides in contact with the filter screen. A discharge pipe is connected to the collection hopper, and the port of the discharge pipe is located directly above the collection tank.
[0006] Preferably, the front end of the treatment tank is equipped with a water inlet, the rear end of the treatment tank is equipped with a water outlet valve, and the upper end of the treatment tank is equipped with a chemical dosing port. The above structure can provide a basic guarantee for the normal operation of the device.
[0007] Preferably, a stirring rod is fixed on the rotating shaft, and the stirring rods are distributed at equal angles about the center of the rotating shaft. Through the action of the stirring rod, the leachate and the agent can be mixed after the agent is added, thus ensuring the treatment effect of the leachate.
[0008] Preferably, the filter screen slides in contact with the inner wall of the treatment box, and a convex ring is provided on the front side of the filter screen. Through the action of the convex ring, the contact area between the convex ring and the treatment box can be extended, ensuring the filtration effect of impurities.
[0009] Preferably, a transmission gear is also fixed on the rotating shaft, and the transmission gear cooperates with the gear ring to transmit power. Through the above structure, a basic guarantee can be provided for the up-and-down reciprocating motion of the gear ring.
[0010] Preferably, the discharge pipe is fixedly connected to the processing box, and the discharge pipe is installed at an angle. By installing the discharge pipe at an angle, the collected impurities can be automatically discharged under the action of gravity, which facilitates the collection of impurities.
[0011] Preferably, a sliding rod is fixed to the upper end of the toothed ring, and the sliding rod is slidably connected to the processing box. When the toothed ring moves, the sliding guide effect between the sliding rod and the processing box can ensure the stability of the toothed ring's movement.
[0012] Preferably, movable carbon adsorption plates are symmetrically fixed on the lower side of the toothed ring, and the width of the movable carbon adsorption plates is less than half the width of the treatment box. By moving the movable carbon adsorption plates up and down, the contact area between the movable carbon adsorption plates and the leachate can be increased, ensuring the adsorption effect of the movable carbon adsorption plates.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This municipal solid waste leachate collection and treatment device adopts a rotary filtration mechanism, which can change the contact position between the filter screen and the leachate in real time, avoiding the filter screen from being blocked and affecting the filtration effect. With the action of the scraper, impurities adhering to the filter screen can be scraped off. In addition, with the action of the collection hopper, discharge pipe and collection box, the impurities can be automatically discharged and collected, eliminating the need for manual cleaning of the filter screen and improving the convenience of the device. Furthermore, with the linkage adsorption mechanism, the movable carbon adsorption plate can move up and down in an orderly manner, so that the leachate can come into contact with the movable carbon adsorption plate multiple times to achieve purification and ensure the purification effect.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-3 This utility model provides a technical solution: a municipal solid waste leachate collection and treatment device, including a treatment box 1 and a motor 2. The motor 2 is fixed to the rear end face of the treatment box 1, and a rotating shaft 3 is fixed to the output end of the motor 2. The rotating shaft 3 is connected to the treatment box 1 by a bearing. A filter screen 302 is fixed on the rotating shaft 3. The filter screen 302 slides in contact with the collection hopper 4. The collection hopper 4 is fixed in the treatment box 1. A scraper 401 is fixed on the collection hopper 4. The scraper 401 slides in contact with the filter screen 302. A discharge pipe 402 is connected to the collection hopper 4. The port of the discharge pipe 402 is located directly above the collection box 403.
[0020] The front end of the treatment tank 1 is equipped with a water inlet 101, the rear end of the treatment tank 1 is equipped with a water outlet 102, and the upper end of the treatment tank 1 is equipped with a chemical dosing port 103; a stirring rod 301 is fixed on the rotating shaft 3, and the stirring rod 301 is distributed at equal angles about the center of the rotating shaft 3; the filter screen 302 slides in contact with the inner wall of the treatment tank 1, and a convex ring 303 is provided on the front side of the filter screen 302;
[0021] When using this municipal solid waste leachate collection and treatment device, such as Figures 1-3 As shown, landfill leachate enters the treatment tank 1 through inlet 101. Simultaneously, motor 2 is started, which drives the rotating shaft 3, stirring rod 301, and filter screen 302 to rotate. The rotation of filter screen 302 changes the contact position between filter screen 302 and leachate. When solid impurities adhere to filter screen 302, the sliding action between filter screen 302 and scraper 401 can scrape off the impurities. The scraped impurities fall into collection hopper 4 and are discharged outward through inclined discharge pipe 402 into collection tank 403 for collection. This prevents filter screen 302 from being blocked and ensures its normal filtration function. After filtration, chemical agents (such as sodium hypochlorite, decolorizing agent, etc.) can be added to the leachate through chemical addition port 103. The added agents, combined with the stirring action of stirring rod 301, can achieve mixing and ensure the treatment effect of leachate.
[0022] A transmission gear 5 is also fixed on the rotating shaft 3, and the transmission gear 5 cooperates with the gear ring 6 to perform transmission; the discharge pipe 402 is fixedly connected to the treatment box 1, and the discharge pipe 402 is installed at an angle; a sliding rod 601 is fixed at the upper end of the gear ring 6, and the sliding rod 601 is slidably connected to the treatment box 1; movable carbon adsorption plates 602 are symmetrically fixed on the lower side of the gear ring 6, and the width of the movable carbon adsorption plates 602 is less than half the width of the treatment box 1;
[0023] During the operation of the device, such as Figures 1-3 As shown, the rotation of the rotating shaft 3 synchronously drives the rotation of the transmission gear 5. Combined with the transmission action between the transmission gear 5 and the gear ring 6, the gear ring 6 can move up and down in an orderly manner. The sliding guide action between the slide rod 601 and the treatment box 1 ensures the stability of the gear ring 6's movement. When the gear ring 6 moves, it synchronously drives the movable carbon adsorption plate 602 to move up and down, causing the movable carbon adsorption plate 602 to repeatedly contact the leachate, further purifying the leachate and ensuring the treatment effect. This is the working principle of this municipal solid waste leachate collection and treatment device.
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
