Description

Technical Field

[0001] This utility model relates to the field of landfill leachate treatment technology, and in particular to a landfill leachate extrusion removal device for power generation. Background Technology

[0002] Waste-to-energy is an innovative technology with significant environmental and energy implications. It primarily uses municipal solid waste as fuel, burning it at high temperatures in specific incineration equipment. During incineration, the chemical energy contained in the waste is converted into heat energy, which in turn generates high-temperature steam to drive a steam turbine, ultimately powering a generator. Before combustion, the waste requires pretreatment, which involves using a squeezing and removal device to remove leachate from the waste.

[0003] In daily work, it has been found that existing landfill leachate removal devices use a simple method of squeezing the waste to remove leachate. However, some leachate remains in the waste and cannot be removed, resulting in poor removal efficiency. Furthermore, the devices are not suitable for multi-stage filtration of the leachate, which can lead to excessive impurities in the leachate, causing pipe blockage and affecting the normal operation of subsequent processes. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as poor leachate removal efficiency and difficulty in filtration, and to propose a leachate extrusion removal device for power generation.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a landfill leachate removal device for power generation, comprising a treatment box and a pressing device. A support is fixedly connected to the lower surface of the treatment box, a drainage area is provided below the treatment box, and an inlet is provided on the surface of the treatment box. The pressing device is disposed within the inner wall of the treatment box and includes a filter plate one and a filter plate two, which are respectively fixedly connected to the inner wall of the treatment box. A baffle is slidably connected to one side of the inner wall of the treatment box. An outlet one and an outlet two are respectively provided on the side of the treatment box near the baffle. An adjusting assembly is provided between the treatment box and the baffle. A pressing cylinder one and a pressing cylinder two are fixedly connected to the surface of the treatment box. The pressing cylinder one and the pressing cylinder two... The outlet is fixedly connected to a first extrusion block and a second extrusion block. The inner wall of the processing box is provided with a shielding component. The surface of the first extrusion block is provided with an auxiliary component. The auxiliary component includes two pushing cylinders fixed to the inner wall of the first extrusion block. The output end of the pushing cylinder is fixedly connected to a piercing part. With the above components, when in use, the garbage can be put into the processing box. The first extrusion cylinder can drive the first extrusion block to move. The first extrusion block and the piercing part, together with the baffle, can squeeze and pierce the garbage. The liquid enters the second filter plate through the first filter plate for double filtration and interception. Then, the second extrusion cylinder is opened, and the second extrusion block is controlled to squeeze in conjunction with the baffle to remove the liquid from the second-filtered garbage. Then, the adjusting component drives the baffle to rise, and the garbage can be pushed away from the first and second discharge ports.

[0006] Preferably, both the first extrusion block and the second extrusion block are composed of a rectangular plate and a scraper at the bottom of the rectangular plate. When the first extrusion block and the second extrusion block move, the scraper at the bottom of the rectangular plate can scrape off the waste on the first filter plate and the second filter plate, which facilitates the feeding of materials.

[0007] Preferably, the adjusting component includes a screw, which is rotatably connected to the inner wall of the processing box and threadedly connected to the inner wall of the baffle. A motor is fixedly connected to the surface of the processing box, and the output end of the motor is fixedly connected to one end of the screw. With the above components, when material needs to be discharged, the motor is turned on, and the motor drives the screw to rotate. The screw can control the baffle to move, thereby removing the constraint on the first and second discharge ports, and material can be discharged.

[0008] Preferably, the shielding assembly includes a shielding member that is slidably connected to the inner wall of the processing box. An auxiliary cylinder is fixedly connected to the surface of the processing box, and the output end of the auxiliary cylinder is fixedly connected to the surface of the shielding member. Through the above components, during the extrusion process, the auxiliary cylinder can drive the auxiliary plate to shield the feed inlet, thereby facilitating the extrusion block to perform the extrusion operation.

[0009] Preferably, the piercing part includes an auxiliary plate fixedly connected to the output end of the push cylinder. Multiple spikes are fixedly connected to the surface of the auxiliary plate. The spikes are connected through the extrusion block. Through the above components, the push cylinder can be opened during the extrusion process, thereby driving the auxiliary plate and spikes to move. The spikes can pierce the waste, thereby facilitating better extrusion and removal of leachate.

[0010] Preferably, the plurality of spikes are arranged at equal intervals on the auxiliary plate, and the head of the spike is tapered. Through the above components, the plurality of spikes can pierce different positions of the garbage, thereby improving the piercing effect.

[0011] Preferably, a scraper ring is fixedly connected to the inner wall of the extrusion block. The scraper ring is through which the barb passes. Through the above-mentioned components, the scraper ring can scrape away the garbage adhering to the barb.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up a squeezing device, the leachate can be filtered in multiple stages through filter plate one and filter plate two, ensuring the purity of the leachate and reducing clogging. Moreover, the pushing cylinder one, squeezing block one, pushing cylinder two, and squeezing block two can squeeze the garbage on filter plate one and filter plate two respectively to remove leachate. The squeezing block one, together with the piercing part in the auxiliary component, can better squeeze and pierce the garbage, thereby allowing the leachate to be squeezed out better and improving the leachate removal effect.

[0014] 2. In this utility model, by setting auxiliary components, during the squeezing process, the push cylinder drives the spike rod to pierce the garbage back and forth, which can destroy the internal structure of the garbage and break the obstruction of the internal liquid flow, so that the leachate that was originally wrapped or adsorbed inside the solid garbage can be squeezed out more smoothly, thereby improving the removal effect.

[0015] 3. In this utility model, by setting a shielding component, the feed inlet can be blocked during the extrusion process, thereby facilitating the extrusion block to better extrude and process the waste. Attached Figure Description

[0023] Please see Figures 1-5 This utility model provides a technical solution: a power generation landfill leachate squeezing removal device, including a treatment box 1 and a squeezing device 4. A support 2 is fixedly connected to the lower surface of the treatment box 1, a drainage area 5 is provided below the treatment box 1, a feed inlet 3 is opened on the surface of the treatment box 1, and the squeezing device 4 is set in the inner wall of the treatment box 1.

[0024] Specifically, the extrusion device 4 includes a filter plate 41 and a filter plate 42. The filter plate 41 and the filter plate 42 are fixedly connected to the inner wall of the processing box 1. A baffle 47 is slidably connected to one side of the inner wall of the processing box 1. The processing box 1 is provided with a discharge port 411 and a discharge port 412 on the side near the baffle 47. An adjustment component 49 is provided between the processing box 1 and the baffle 47. An extrusion cylinder 43 and an extrusion cylinder 44 are fixedly connected to the surface of the processing box 1. An extrusion block 45 and an extrusion block 46 are fixedly connected to the output ends of the extrusion cylinder 43 and the extrusion cylinder 44, respectively. A shielding component 410 is provided on the inner wall of the processing box 1. An auxiliary component 48 is provided on the surface of the extrusion block 45. The auxiliary component 48 includes two push cylinders 482 fixed to the inner wall of the extrusion block 45. A piercing part is fixedly connected to the output end of the push cylinder 482.

[0025] In this embodiment: When in use, the garbage can be placed in the processing box 1. The squeezing cylinder 43 can drive the squeezing block 45 to move. The squeezing block 45 and the piercing part, together with the baffle 47, can squeeze and pierce the garbage. The liquid enters the filter plate 42 through the filter plate 41 for double filtration and interception. Then, the squeezing cylinder 44 is opened, and the squeezing block 46 is controlled to squeeze in conjunction with the baffle 47 to remove the liquid from the secondary filtered garbage. Then, the adjusting component 49 drives the baffle 47 to rise, so that the garbage can be pushed away from the discharge port 411 and the discharge port 412.

[0026] Specifically, both extrusion block 1 45 and extrusion block 2 46 are composed of a rectangular plate and a scraper at the bottom of the rectangular plate. When extrusion block 1 45 and extrusion block 2 46 move, the scraper at the bottom of the rectangular plate can scrape off the garbage on filter plate 1 41 and filter plate 2 42, making it easier to feed materials.

[0027] Specifically, the adjustment assembly 49 includes a screw 492, which is rotatably connected to the inner wall of the processing box 1 and threadedly connected to the inner wall of the baffle 47. A motor 491 is fixedly connected to the surface of the processing box 1, and the output end of the motor 491 is fixedly connected to one end of the screw 492.

[0028] In this embodiment: when it is necessary to unload materials, the motor 491 is turned on, the motor 491 drives the screw 492 to rotate, the screw 492 can control the baffle 47 to move, thereby removing the restraint on the discharge port 1 411 and the discharge port 2 412, so that the material can be unloaded.

[0029] Specifically, the shielding assembly 410 includes a shielding member 4102, which is slidably connected to the inner wall of the processing box 1. An auxiliary cylinder 4101 is fixedly connected to the surface of the processing box 1. The output end of the auxiliary cylinder 4101 is fixedly connected to the surface of the shielding member 4102. During the extrusion process, the auxiliary cylinder 4101 can drive the auxiliary plate 481 to shield the feed port 3, thereby facilitating the extrusion block 45 to perform the extrusion operation.

[0030] Specifically, the piercing part includes an auxiliary plate 481 fixedly connected to the output end of the push cylinder 482. Multiple spikes 483 are fixedly connected to the surface of the auxiliary plate 481, and the spikes 483 are connected through the extrusion block 45.

[0031] In this embodiment: During the squeezing process, the push cylinder 482 can be opened, thereby driving the auxiliary plate 481 and the spike rod 483 to move. The spike rod 483 can pierce the garbage, thereby facilitating better squeezing and removal of leachate.

[0032] Specifically, multiple spikes 483 are arranged at equal intervals on the auxiliary plate 481, and the heads of the spikes 483 are tapered.

[0033] In this embodiment, multiple spikes 483 can pierce different locations of the waste, improving the piercing effect.

[0034] Specifically, a scraper ring 484 is fixedly connected to the inner wall of the extrusion block 45. The scraper ring 484 allows the spike rod 483 to pass through, and the scraper ring 484 can scrape away the garbage adhering to the spike rod 483.

[0035] Working principle: During the initial processing of waste, the waste is first placed into the processing tank 1 through the feed inlet 3. When it is necessary to squeeze out leachate, the auxiliary cylinder 4101 is opened. The auxiliary cylinder 4101 drives the blocking component 4102 to block the feed inlet 3. At the same time, the squeezing cylinder 43 drives the squeezing block 45 to move, pushing the waste and squeezing it in conjunction with the baffle 47. The leachate is first initially filtered through the filter plate 41, and then finely filtered through the filter plate 42. The liquid is then discharged through the drain. During the squeezing process, the squeezing block 45 can open the pushing cylinder 482, which drives the auxiliary cylinder 4101 to move the processing tank 1. Plate 481 and spike 483 move, spike 483 can pierce the garbage back and forth, scraper ring 484 can clean the surface of spike 483, and can better squeeze out and remove liquid. Then squeeze cylinder 2 44 can be opened, squeeze cylinder 2 44 drives squeeze block 2 46 to move, squeeze the garbage and impurities on filter plate 2 42 to remove leachate. After a batch of garbage is processed, motor 491 is turned on, motor 491 and screw 492 can drive baffle 47 to move, so that baffle 47 can no longer block discharge port 1 411 and discharge port 2 412. The garbage is pushed out by squeeze block 1 45 and squeeze block 2 46, and the use is completed.
