Description

Technical Field

[0001] This utility model relates to the field of soil heavy metal pollution remediation technology, and in particular to a soil heavy metal pollution separation and remediation device. Background Technology

[0002] Heavy metal pollution in soil refers to the phenomenon where human activities introduce heavy metals into the soil environment, causing the heavy metal content in the soil to exceed the natural background value and harming the ecosystem and human health. Heavy metals are difficult to degrade in soil, easily accumulate through the food chain, and ultimately affect human health.

[0003] For example, announcement number CN222447291U discloses a heavy metal contaminated soil screening device. This heavy metal contaminated soil screening device includes: a shell assembly, inside which a screening structure assembly is installed; a first air jet structure is installed at the upper end of the screening structure assembly; an air jet pipe is installed at the lower end of the first air jet structure; a rocking spring is installed at the lower end of the air jet pipe; a mounting frame is installed at the upper end of the rocking spring; a first screen is installed at the upper end of the mounting frame; a conveying assembly is installed at the upper end of the shell assembly; a storage box is installed at the upper end of the conveying assembly; a crushing rod is installed inside the storage box; and a conveying frame is installed at the lower end of the storage box. This device effectively prevents the soil from being manually poured into the screening device during screening, which could lead to soil clumping and clogging of the filter screen, rendering the soil unusable.

[0004] This patent can avoid the problem of the filter screen getting clogged when the soil is clumped. However, the filter screen of the existing device does not have a disassembly structure. Although an air jet pipe is provided to clean the impurities on the surface of the filter screen, after filtering a lot of impurities, the surface of the filter screen will absorb a lot of dirt. Since it cannot be disassembled, it is inconvenient to clean, which affects the screening and filtration efficiency of heavy metal contaminated soil.

[0005] Therefore, we propose a novel soil heavy metal pollution separation and purification device. Utility Model Content

[0006] The purpose of this invention is to solve the problem that the filter screen of the existing device does not have a detachable structure. Although an air jet pipe is provided to clean the impurities on the surface of the filter screen, after filtering a lot of impurities, the surface of the filter screen will absorb a lot of dirt. Since it cannot be disassembled, it is inconvenient to clean, which affects the screening and filtration efficiency of soil contaminated with heavy metals.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a soil heavy metal pollution separation and purification device, comprising a shell assembly, a feed inlet at the top of the shell assembly, and a disassembly and assembly assembly inside the shell assembly, the disassembly and assembly assembly comprising two sets of mounting brackets, each set of mounting brackets having a slot on its inner wall, a set of filter screens inside the two sets of mounting brackets, each filter screen having a slot on both sides, a spring inside the slot, a push plate connected to one side of the spring, an insert block connected to one side of the push plate, and a lever connected to the front end of the push plate.

[0008] Furthermore, the surface of the insert has a bevel, and the insert and the slot form a mating connection, which facilitates the fixing of the filter screen.

[0009] Furthermore, the outer surface of the push plate is in contact with the inner wall of the slot, and the push plate and the spring form an elastic structure, which can facilitate the pushing of the insert block.

[0010] Furthermore, the outer shell assembly is provided with an angle adjustment component at the top of the disassembly assembly, and the angle adjustment component includes a support plate, which can play a supporting role.

[0011] Furthermore, a rotating plate is rotatably connected to the front surface of the support plate, and four sets of air jet pipes are equidistantly connected to the front surface of the rotating plate. The air jet pipes can conveniently clean the surface impurities of the filter screen.

[0012] Furthermore, the rear end of the rotating plate is connected to a first rotating shaft, and the surface of the first rotating shaft is connected to the output end of an electric push rod. The rotating plate can be easily pushed through the first rotating shaft and the electric push rod.

[0013] Furthermore, a second rotating shaft is connected to the rear end of the electric actuator.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, after the soil has been screened and filtered for a long time, the insert can be pulled out of the slot by pushing the pusher inward, and then the filter screen can be pulled outward to complete the disassembly. After that, the dirt on the filter screen can be cleaned. This avoids the problem that the existing filter screen does not have the function of disassembly and cleaning, which affects the screening and filtration efficiency.

[0016] 2. In this utility model, when it is necessary to blow away and clean the impurities on the filter screen, the electric push rod can be activated according to the actual situation to push the rotating plate to drive the jet pipe to adjust the angle, which facilitates the adjustment of the jet angle and intensity and improves the cleaning efficiency.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Examples, such as Figure 1 - Figure 3 As shown, this utility model provides a soil heavy metal pollution separation and purification device, including a shell assembly 1. The top of the shell assembly 1 is provided with a feed inlet 2. The shell assembly 1 is provided with a disassembly and assembly assembly 3. The disassembly and assembly assembly 3 includes two sets of mounting brackets 301. The inner walls of the two sets of mounting brackets 301 are provided with slots 302. The inside of the two sets of mounting brackets 301 is provided with a filter screen 303. The inside of both sides of the filter screen 303 is provided with slots 304. The inside of the slots 304 is provided with springs 305. One side of the spring 305 is connected to a push plate 306. One side of the push plate 306 is connected to an insert block 307. The front end of the push plate 306 is connected to a lever block 308.

[0025] like Figure 3 As shown, the surface of the insert 307 has a bevel, and the insert 307 and the slot 302 form an insertion connection, which can facilitate the fixing of the filter screen 303.

[0026] like Figure 2 and Figure 3 The outer surface of the push plate 306 is in contact with the inner wall of the slot 304, and the push plate 306 and the spring 305 form an elastic structure, which can easily push the insert block 307.

[0027] like Figure 4 As shown, the outer shell assembly 1 is provided with an angle adjustment assembly 4 at the top of the disassembly assembly 3. The angle adjustment assembly 4 includes a support plate 401, which can provide support.

[0028] like Figure 1 and Figure 4 As shown, a rotating plate 402 is rotatably connected to the front surface of the support plate 401, and four sets of air jet pipes 403 are equidistantly connected to the front surface of the rotating plate 402. The air jet pipes 403 can conveniently clean the surface impurities of the filter screen 303.

[0029] like Figure 1 and Figure 4 As shown, the rear end of the rotating plate 402 is connected to a first rotating shaft 404, and the surface of the first rotating shaft 404 is connected to the output end of an electric push rod 405. The rotating plate 402 can be easily pushed through the first rotating shaft 404 and the electric push rod 405.

[0030] like Figure 4 As shown, the rear end of the electric actuator 405 is connected to a second rotating shaft 406.

[0031] The overall effect of this embodiment is as follows: After the device separates heavy metal pollution from the soil, since the existing device is publicly available technology, it will not be described in detail here. Impurities on the surface of the filter screen 303 can be cleaned through the air jet pipe 403. When stains appear on the surface of the filter screen 303 and it needs to be disassembled for cleaning, two sets of levers 308 can be pushed inwards simultaneously. This allows the levers 308 to drive the push plate 306 to compress the spring 305, causing the insert block 307 to be pulled out of the slot 302. Then, the filter screen 303 is pulled outwards, allowing it to be removed from the mounting bracket 301, thus completing the disassembly of the filter screen 303. Afterwards, the stains on the filter screen 303 can be cleaned. The cleaned filter screen 303 can then be... The filter screen 303 is pushed into the two sets of mounting brackets 301. When the angled opening of the insert block 307 is squeezed, it will automatically retract. After the filter screen 303 is pushed into the mounting bracket 301, the spring 305 will push the push plate 306 to drive the insert block 307 into the slot 302 for fixation. This completes the disassembly and cleaning of the filter screen 303, avoiding the problem that the existing filter screen 303 does not have the function of disassembly and cleaning, which affects the screening and filtration efficiency. When the electric push rod 405 is turned on, the output end of the electric push rod 405 will rotate with the first rotating shaft 404, thereby pushing the rotating plate 402 to adjust the direction through the first rotating shaft 404, and then driving the jet pipe 403 to adjust the angle, which facilitates the jet angle and intensity and improves the cleaning efficiency.

[0032] Working principle: After prolonged sieving and filtering of soil, the insert block 307 can be pulled out of the slot 302 by pushing the pusher block 308 inward. Then, the filter screen 303 can be pulled outward to complete the disassembly. After that, the dirt on the filter screen 303 can be cleaned. This avoids the problem that the existing filter screen 303 does not have the function of disassembly and cleaning, which affects the sieving and filtering efficiency. When it is necessary to blow away impurities on the filter screen 303, the electric push rod 405 can be activated according to the actual situation. This pushes the rotating plate 402 to drive the jet pipe 403 to adjust the angle, which facilitates the adjustment of the jet angle and intensity and improves the cleaning efficiency.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
