Abstract
Description
Technical Field
[0001] This utility model relates to the field of leachate purification technology, specifically a landfill leachate purification and treatment device. Background Technology
[0002] Waste is a waste product that has lost its value and cannot be utilized. It is an important link in the material cycle and consists of solid and fluid substances that are not needed or useful. Waste needs to be treated in multiple steps, and leachate treatment is one of the most important steps to prevent the waste from corroding.
[0003] Application number CN202322754520.9 discloses a comprehensive treatment device for landfill leachate, comprising a base plate, support columns, a top plate, a funnel pool, a compression pool, a filter frame, a baffle, an installation / removal assembly, and a pressure plate. The support columns are uniformly and fixedly connected to the top of the base plate, the top plate is fixedly connected to the top of the support columns, the funnel pool is fixedly connected to the support columns and positioned above the base plate, and the compression pool is fixedly connected to the support columns and positioned above the funnel pool, with the compression pool opposite to the funnel pool. This utility model belongs to the field of waste treatment technology, specifically referring to a comprehensive treatment device for landfill leachate. The installation / removal assembly facilitates the installation and removal of the filter frame within the compression pool, making it easy to remove waste from the filter frame and improving the convenience of waste treatment. Water in the waste is forced out into the funnel pool through the leak and the filter frame, and the waste liquid is discharged into the discharge pipe through the discharge hole.
[0004] When filtering garbage, the leachate flows relatively statically within the filter frame. Some impurities may flow directly through the filter frame along the leachate flow, resulting in low interception efficiency. In static filtration, silt particles are prone to localized accumulation on the filter screen, clogging some filter holes, making it difficult for subsequent leachate to pass through and reducing overall filtration efficiency. If the filter frame is stationary, the leachate may concentrate in a certain area, resulting in some filtration area being idle and the filtration capacity of the filter frame not being fully utilized. Utility Model Content
[0005] The purpose of this invention is to provide a landfill leachate purification and treatment device to solve the problem of low interception efficiency of filter components.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a landfill leachate purification and treatment device, comprising a fixing component and a screening component. The screening component is installed on one side above the fixing component. The fixing component includes a fixing frame, and a connecting frame is welded to the left outer wall of the fixing frame. A motor is fixedly installed on the bottom outer wall of the connecting frame. A rotating wheel and a positioning wheel are rotatably connected to the upper surface of the connecting frame. A belt is fitted around the rotating wheel and the positioning wheel. The output end of the motor extends vertically upward and connects to the rotating wheel. A sliding groove is formed on the inner wall around the top of the fixing frame. Two pulleys are slidably connected to the inner walls on both sides of the sliding groove. A connecting rod is provided on one side of the pulley. One end of the connecting rod extends inward and is fixedly installed with a screening container. A hinged rail is hinged to the top of the screening container and the positioning wheel.
[0008] The purpose of this setup is that during the operation of the device, the motor is fixed to the bottom of the connecting frame. After being powered on, the output shaft rotates vertically upward, directly driving the rotating wheel to rotate coaxially. The rotating wheel and the positioning wheel form a belt drive system through a belt, transmitting the motor power to the positioning wheel.
[0009] The positioning wheel rotates in a circular motion driven by the belt, and the connection point with the hinged rail produces periodic displacement. One end of the hinged rail is eccentrically hinged to the positioning wheel, and the other end is hinged to the top of the screening container, converting the circular motion of the wheel into the reciprocating linear motion of the screening container.
[0010] The screening container is connected to the top groove of the fixed frame by pulleys at the ends of the connecting rods on both sides, ensuring that the movement trajectory is straight and reciprocating along the direction of the groove. The leachate enters from the top inlet of the screening container and is evenly distributed on the surface of the filter screen under the action of reciprocating motion. The inertial force generated by the reciprocating motion makes the solid particles in the leachate fully contact the filter screen, accelerates the speed of the liquid passing through the filter screen, and prevents the filter screen from clogging.
[0011] The motor, as a power source, can stably provide power and drive the positioning wheel to rotate via belt drive. Compared with some complex power transmission methods, belt drive has the advantages of buffering and vibration absorption, overload slippage protection, etc., which can effectively prevent the motor and other components from being damaged due to overload. At the same time, it can ensure that the screening container can reciprocate and slide stably and continuously, so as to achieve effective screening of leachate.
[0012] By using articulated rails to connect the positioning wheel and the screening container, and combining the sliding cooperation of the chute and pulley, the reciprocating motion trajectory of the screening container is precisely controllable, ensuring that the leachate can pass through the filter screen evenly during the screening process, thereby improving screening efficiency and quality.
[0013] Furthermore, a filter screen is provided on the inner wall of the bottom surface of the screening container.
[0014] The purpose of this setup is that during the operation of the device, when the screening container slides back and forth, the leachate enters the screening container, solid impurities are intercepted by the filter screen, and the liquid passes through the filter screen to continue the subsequent processing.
[0015] Furthermore, a support frame is fixedly placed inside the fixed frame, and a sliding bucket is welded to the top of the support frame.
[0016] The purpose of this design is that, during the operation of the device, the support frame is used to support the hopper, ensuring that it is securely installed inside the fixed frame.
[0017] Furthermore, the chute is inclined and positioned directly below the screening container.
[0018] The purpose of this design is that, during the operation of the device, because the chute is tilted and positioned directly below the screening container, the leachate passing through the filter screen of the screening container can fall smoothly into the chute due to gravity.
[0019] Furthermore, a water storage tank is fixedly placed on the right side of the fixing frame, and the tail end of the chute is fixedly connected to the left inner wall of the water storage tank.
[0020] The purpose of this design is that, during the operation of the device, the tail end of the chute is connected to the inner wall of the left side of the water storage tank, and the leachate flows into the water storage tank along the chute for storage.
[0021] Furthermore, the chute is connected to the cavity of the water storage tank.
[0022] The purpose of this design is to ensure that the chute is connected to the water storage tank cavity during the operation of the device, so that the leachate can flow from the chute into the water storage tank without obstruction.
[0023] This utility model has the following beneficial effects:
[0024] (1) This utility model uses a motor, a hinged rail and a pulley. The motor is the power source and can stably provide power. It drives the positioning wheel to rotate through the belt drive. The hinged rail connects the positioning wheel and the screening container. Combined with the sliding cooperation of the chute and the pulley, the reciprocating motion trajectory of the screening container is accurate and controllable, ensuring that the leachate can pass through the filter screen evenly during the screening process, thereby improving screening efficiency and quality.
[0025] (2) With the setting of the sluice and the water storage tank, the sluice is inclined and set directly below the screening container. The leachate passing through the filter screen of the screening container can fall smoothly into the sluice by gravity. The tail end of the sluice is connected to the inner wall of the left side of the water storage tank. The leachate flows into the water storage tank for storage along the sluice.
[0026] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0035] Please see Figures 1-4As shown, this utility model is a landfill leachate purification and treatment device, including a fixing component 1 and a screening component 2. The screening component 2 is installed on one side above the fixing component 1. The fixing component 1 includes a fixing frame 101. A connecting frame 105 is welded to the left outer wall of the fixing frame 101. A motor 205 is fixedly installed on the bottom outer wall of the connecting frame 105. A rotating wheel 206 and a positioning wheel 207 are rotatably connected to the upper surface of the connecting frame 105. The rotating wheel 206 and the positioning wheel 207 are respectively connected to the positioning wheel 207. The outer side of the 07 is fitted with a belt 208. The output end of the motor 205 extends vertically upward and connects to the rotating wheel 206. The top of the fixed frame 101 is provided with a sliding groove 106 on the inner wall around the perimeter. Two pulleys 201 are slidably connected to the inner walls on both sides of the sliding groove 106. A connecting rod 202 is provided on one side of the pulley 201. One end of the connecting rod 202 extends inward and is fixedly installed with a screening container 203. The top of the screening container 203 and the positioning wheel 207 are hinged with a hinged rail 209.
[0036] The purpose of this setup is that during the operation of the device, the motor 205 is fixed to the bottom surface of the connecting frame 105. After being powered on, the output shaft rotates vertically upward, directly driving the rotating wheel 206 to rotate coaxially. The rotating wheel 206 and the positioning wheel 207 form a belt drive system through the belt 208, which transmits the motor power to the positioning wheel 207.
[0037] The positioning wheel 207 moves in a circular motion driven by the belt, and the connection point with the hinged rail 209 produces periodic displacement. One end of the hinged rail 209 is eccentrically hinged to the positioning wheel 207, and the other end is hinged to the top of the screening container 203, converting the circular motion of the wheel into the reciprocating linear motion of the screening container.
[0038] The screening container 203 is connected to the top slide groove 106 of the fixed frame 101 by the pulleys 201 at the ends of the connecting rods 202 on both sides, ensuring that the movement trajectory is straight and reciprocating along the slide groove. The leachate enters from the top inlet of the screening container 203 and is evenly distributed on the surface of the filter screen 204 under the action of reciprocating motion. The inertial force generated by the reciprocating motion makes the solid particles in the leachate fully contact the filter screen 204, accelerating the speed of the liquid passing through the filter screen, while preventing the filter screen from clogging.
[0039] The motor 205 serves as a power source, providing stable power. It drives the positioning wheel 207 to rotate via the belt 208. Compared to some complex power transmission methods, the belt 208 drive has advantages such as buffering and vibration absorption, and overload slippage protection. It can effectively prevent the motor 205 and other components from being damaged due to overload. At the same time, it can ensure that the screening container 203 can reciprocate stably and continuously, thus achieving effective screening of leachate.
[0040] The positioning wheel 207 and the screening container 203 are connected by the hinged rail 209, and the sliding cooperation between the chute 106 and the pulley 201 makes the reciprocating motion trajectory of the screening container 203 precise and controllable, ensuring that the leachate can pass through the filter screen 204 evenly during the screening process, thereby improving screening efficiency and quality.
[0041] A filter screen 204 is provided on the inner wall of the bottom surface of the screening container 203.
[0042] The purpose of this setup is that during the operation of the device, when the screening container 203 reciprocates, the leachate enters the screening container 203, where solid impurities are intercepted by the filter screen 204, while the liquid passes through the filter screen to continue the subsequent processing.
[0043] A support frame 102 is fixedly placed inside the fixed frame 101, and a slide 103 is welded to the top of the support frame 102.
[0044] The purpose of this arrangement is that, during the operation of the device, the support frame 102 is used to support the hopper 103, so that it is stably installed inside the fixed frame 101.
[0045] The hopper 103 is inclined and positioned directly below the screening container 203.
[0046] The purpose of this arrangement is that, during the operation of the device, because the hopper 103 is tilted and located directly below the screening container 203, the leachate passing through the filter screen 204 of the screening container 203 can fall smoothly into the hopper 103 by gravity.
[0047] A water storage tank 104 is fixedly placed on the right side of the fixed frame 101, and the tail end of the chute 103 is fixedly connected to the left inner wall of the water storage tank 104.
[0048] The purpose of this arrangement is that, during the operation of the device, the tail end of the chute 103 is connected to the inner left wall of the water storage tank 104, and the leachate flows into the water storage tank 104 along the chute 103 for storage.
[0049] The chute 103 is connected to the cavity of the water storage tank 104.
[0050] The purpose of this arrangement is that, during the operation of the device, the chute 103 is connected to the cavity of the water storage tank 104, ensuring that the leachate can flow from the chute 103 into the water storage tank 104 without obstruction.
[0051] When in use, the motor 205 drives the rotating wheel 206 to rotate after being powered on, and drives the positioning wheel 207 to rotate synchronously through the belt 208. The eccentric hinge point of the positioning wheel 207 drives the hinge rail 209 to swing periodically, converting the circular motion into linear motion.
[0052] The hinged rail 209 pushes the screening container 203 to slide horizontally back and forth along the slide 106. The rolling cooperation between the pulley 201 and the slide 106 ensures smooth movement. The leachate is injected from the top inlet of the screening container 203 and is evenly distributed on the surface of the filter screen 204 under the action of reciprocating vibration. The reciprocating motion of the screening container 203 generates inertial force, which causes solid impurities on the filter screen 204 to gather towards the edge, thus avoiding clogging of the filter holes.
[0053] The filtered leachate passes through the filter screen 204 and falls into the lower hopper 103. The hopper 103 is made of polypropylene with a smooth inner wall to reduce liquid residue. The hopper is tilted at an angle of 30°-45° to ensure rapid liquid flow. The leachate flows along the hopper 103 into the water storage tank 104. The two are sealed together by welding to ensure no leakage.
[0054] This device achieves efficient pretreatment of leachate by combining mechanical vibration screening with gravity flow. The eccentric wheel and hinged rod convert rotational motion into linear vibration, forming a closed loop from screening and flow to storage, providing stable water quality conditions for subsequent advanced treatment.
[0055] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
