Description

Technical Field

[0001] This utility model relates to the technical field of municipal solid waste leachate treatment devices, and in particular to a municipal solid waste leachate treatment device. Background Technology

[0002] Household waste can generally be divided into four categories: kitchen waste, recyclable waste, other waste, and hazardous waste. During the stacking and transportation of household waste, rainwater, snowmelt, and other natural liquids mix with the waste, eventually accumulating into a mixed organic wastewater. After fermentation, this produces leachate. Waste containing leachate cannot be fully incinerated, and it pollutes treatment plants or roads during landfill and transportation.

[0003] Therefore, it is necessary to use a municipal solid waste leachate treatment device to treat the leachate and achieve solid-liquid separation of the waste. Existing municipal solid waste leachate treatment devices only squeeze the waste to discharge the leachate. Although the device can collect the leachate to a certain extent, the leachate discharge effect is poor and it is not suitable for industrial applications.

[0004] Therefore, it is necessary to propose a technical means to solve the above-mentioned defects. Utility Model Content

[0024] Please see Figures 1 to 4 A municipal solid waste leachate treatment device includes a waste crushing box 10, a waste squeezing box 20 installed below the waste crushing box 10, and a material receiving assembly 30 installed below the waste squeezing box 20. The waste crushing box 10 contains a cutter roller assembly for crushing waste and a first drive assembly installed on the side of the waste crushing box 10 for driving the cutter roller assembly. The waste squeezing box 20 contains two squeezing plates 201 on opposite sides for squeezing waste, and a second drive assembly connected to the two squeezing plates 201 for driving the two squeezing plates 201 to move closer together to squeeze the waste.

[0025] The material receiving assembly 30 includes a first receiving box 301 for receiving leachate, a second receiving box 302 for receiving waste, installed below the waste compression box 20, and a third driving component connected to the first receiving box 301 and the second receiving box 302 for driving the first receiving box 301 and the second receiving box 302 to align with the discharge port of the waste compression box 20 as needed.

[0026] Specifically, the leachate treatment device for municipal solid waste involved in this utility model operates by placing waste into a waste crushing box 10, where it is crushed by a guide roller assembly. The crushed waste then enters a waste squeezing box 20, where, driven by a second drive assembly, two squeezing plates 201 press the waste to expel the leachate. At this time, a first receiving box 301 aligns with the waste squeezing box 20, allowing the expelled leachate to fall into the first receiving box 301 for collection. After squeezing is complete, a third drive assembly moves a second receiving box 302 to align with the discharge port of the waste squeezing box 20. The squeezing plates 201 then release the waste under the drive of the second drive unit, allowing it to fall into the second receiving box 302 for collection. This completes one working sequence. In this embodiment, the waste crushing box 10 effectively crushes the waste, allowing the leachate to be fully expelled during squeezing by the squeezing plates 201, thus improving the squeezing effect and consequently the leachate treatment effect.

[0027] The present invention relates to a municipal solid waste leachate treatment device, which, through the arrangement of a waste crushing box 10, a waste squeezing box 20 and a material receiving assembly 30, achieves good leachate treatment effect and is suitable for industrial applications.

[0028] In one specific embodiment, the cutter roller assembly includes a first cutter roller 101 and a second cutter roller 102 installed inside the waste crushing bin 10 and arranged horizontally opposite each other. Specifically, both the first cutter roller 101 and the second cutter roller 102 include a roller body and a cutting disc 103 installed on the outside of the roller body. During operation, the first drive assembly drives the roller body to rotate, which in turn drives the cutting disc 103 to rotate, thereby crushing the waste.

[0029] In one specific embodiment, the first drive assembly includes a first transmission gear 104, a second transmission gear 105, and a first motor 106. The first transmission gear 104 and the second transmission gear 105 are respectively mounted on the ends of the first cutter roller 101 and the second cutter roller 102, and mesh with each other. The first motor 106 is connected to the first cutter roller 101. Specifically, during operation, the first motor 106 is connected to the first cutter roller 101 through a reducer 107 to drive the first cutter roller 101 to rotate. This, in turn, drives the second transmission gear 105 to rotate through the meshing of the first transmission gear 104 and the second transmission gear 105, thereby causing the first cutter roller 101 and the second cutter roller 102 to crush the waste during rotation.

[0030] In one specific embodiment, the second drive assembly includes two hydraulic cylinders 202 mounted on opposite sides of the waste compression bin 20; each of the two hydraulic cylinders 202 is connected to its adjacent compression plate 201. Specifically, during operation, the two hydraulic cylinders 202 operate, thereby driving the connected compression plates 201 to move closer together, thereby compressing the waste.

[0031] In one specific embodiment, the material receiving assembly 30 includes a mounting box 303 installed below the waste compression box 20; the upper part of the mounting box 303 is provided with a communication port aligned with the discharge port of the waste compression box 20; the first receiving box 301 and the second receiving box 302 are connected and installed side by side in the mounting box 303; the third driving component is connected to the first receiving box 301 and the second receiving box 302, and is used to drive the first receiving box 301 and the second receiving box 302 to move synchronously within the mounting box 303, so that the inlets of the first receiving box 301 and the second receiving box 302 can be moved as needed to fit with the communication port. Specifically, in this embodiment, when the squeezing plate 201 squeezes the garbage to filter out the leachate, the first receiving box 301 is located inside the connecting port and aligned with the garbage squeezing box 20 to receive the falling leachate. After the leachate is completely filtered out, the second receiving box 302 moves into the connecting port under the drive of the third driving component and aligns with the garbage squeezing box 20 to receive the garbage falling from the garbage squeezing box 20.

[0032] In one specific embodiment, the third driving component includes a slider, a lead screw 304, a moving block 305, and a second motor 306; the bottom of the mounting box 303 is provided with a slide rail 307; the slider is slidably mounted on the slide rail 307 and connected to the first receiving box 301 and the second receiving box 302; the lead screw 304 is installed inside the mounting box 303 and is horizontally located on one side wall of the mounting box 303; the moving block 305 is installed on the lead screw 304 and connected to the second receiving box 302, and is used to drive the second receiving box 302 and the first receiving box 301 to move along the slide rail 307 via the slider when the lead screw 304 rotates, so that the feed inlets of the first receiving box 301 and the second receiving box 302 move as needed to fit with the communication port; the second motor 306 is installed inside the mounting box 303 and connected to the lead screw 304, and is used to drive the lead screw 304 to rotate.

[0033] In one specific embodiment, the first receiving box 301 includes a box body 308 and a filter plate 309 installed above the box body 308; the filter plate 309 is provided with a plurality of equally spaced grooves 310; the bottom of the grooves 310 is provided with filter holes 311 for communicating with the box body 308. In this embodiment, the filter plate 309 effectively prevents garbage from entering the box body 308 during garbage compression and the switching of positions between the box body 308 and the second receiving box 302; at the same time, the grooves 310 create a certain gap between the garbage and the filter holes 311, allowing leachate to flow effectively into the box body 308 through the filter holes 311. Specifically, the upper part of the filter holes 311 is chamfered to facilitate the flow of leachate into the filter holes 311.

[0034] In one specific embodiment, a scraper 203 is provided below the squeezing plate 201 corresponding to the partition 310 for extending into the partition 310. In this embodiment, during operation, after the leachate is squeezed and filtered, the second motor 306 drives the lead screw 304 to rotate, thereby driving the moving block 305 to move, so that the first receiving box 301 and the second receiving box 302 move synchronously along the guide rail, and then the second receiving box 302 moves and aligns with the garbage squeezing box 20. During this process, through the setting of the scraper 203, when the filter plate 309 moves, it can effectively scrape the garbage located in the partition 310 and push it into the second receiving box 302, thereby ensuring the filtration effect of the next filter hole 311.

[0035] In one specific embodiment, the side of the mounting box 303 is provided with a clearance groove 312; the side of the box body 308 is provided with a discharge port 313 for discharging leachate; the side of the second receiving box 302 is provided with a door 314 for removing waste; both the discharge port 313 and the door 314 are located within the clearance groove 312. Specifically, in this embodiment, the clearance groove 312 prevents interference between the discharge port 313 and the door 314 and the mounting box 303 when the first receiving box 301 and the second receiving box 302 move.

[0036] The present invention relates to a municipal solid waste leachate treatment device, which, through the arrangement of a waste crushing box 10, a waste squeezing box 20 and a material receiving assembly 30, achieves good leachate treatment effect and is suitable for industrial applications.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
