Description

Technical Field

[0001] This utility model relates to the technical field of sludge solidification treatment equipment, specifically to a sludge solidification pretreatment device for environmental remediation. Background Technology

[0002] Currently, scouring and siltation frequently occur in natural rivers, easily leading to water hazards and hindering water conservancy development. Patent number CN202120839254.8 discloses a sludge solidification pretreatment device for water environment management. The filter cylinder rotates within the filter chamber, separating most of the water from the sludge, shortening the drying time, reducing energy consumption, and achieving energy conservation and environmental protection. However, during the use of sludge solidification pretreatment equipment for environmental management, the drying process generates significant amounts of water vapor, which also carries a large amount of odor. Direct emission of these odors and water vapor can easily impact the surrounding environment. Therefore, we propose a sludge solidification pretreatment device for environmental management. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a sludge solidification pretreatment device for environmental remediation.

[0004] The technical solution adopted by this utility model to solve its technical problem is a sludge solidification pretreatment device for environmental governance, including a frame, in which a pretreatment equipment body for sludge solidification is mounted, and a ring pipe seat for support is mounted on the outer peripheral surface of the pretreatment equipment body. A turbine fan for air extraction is mounted inside the ring pipe seat, and check valves located on both sides of the turbine fan are mounted on the inner side of the ring pipe seat.

[0005] The end of the ring tube seat away from the main body of the pretreatment equipment is screwed with a support sleeve, and a cross ring seat for support is screwed in the sleeve. The cross ring seat is equipped with an activated carbon plate and a filter screen plate for filtration.

[0006] By adopting the above technical solution, when using the sludge solidification pretreatment equipment for environmental remediation, the turbine fan in the outer ring pipe seat of the pretreatment equipment can operate and extract air from the equipment when the sludge is dried to a certain extent. This allows the odor carried in the air to be guided and discharged to a designated location, thereby reducing the impact of direct odor discharge and enabling the pretreatment equipment to pretreat the sludge more stably.

[0007] When the gas is extracted from the main body of the pretreatment equipment using a turbine fan, it can easily enter the pipe sleeve, allowing the filter plate and activated carbon plate in the cross ring seat inside the pipe sleeve to filter and purify the extracted gas to a certain extent. This facilitates the pretreatment of the air and odors, making it easier to process and discharge the gas more stably in the future. At the same time, the pipe sleeve is easy to disassemble and replace, making it convenient to disassemble and replace the internal structure of the pipe sleeve.

[0008] Specifically, a filter cotton core is snapped into the inner side of the sleeve, which abuts against the cross-shaped seat.

[0009] By adopting the above technical solution, the filter cotton core in the tube sleeve can be easily used in conjunction with the activated carbon plate and filter screen plate to facilitate the filtration of the extracted air and odors, thereby improving the pretreatment effect and making subsequent treatment more convenient.

[0010] Specifically, the inner side of the frame is fitted with a vertical pipe for support, and a bend for guiding flow is rotatably installed at the end of the vertical pipe away from the frame. A corrugated pipe for guiding flow is fitted between the bend and the pipe sleeve.

[0011] By adopting the above technical solution, the corrugated pipe facilitates the flow of air after preliminary filtration and allows it to enter the vertical pipe through the bend, so that the pre-treated air and odors can be discharged to the designated location.

[0012] Specifically, the top surface of the frame is equipped with a shut-off valve that communicates with the vertical pipe, and the top surface of the frame is also equipped with a fan that communicates with the shut-off valve.

[0013] By adopting the above technical solution, the fan can conveniently assist in drawing gas into the vertical pipe, and the air outlet of the fan can be connected to the external exhaust pipe, so that the gas after preliminary filtration can be discharged to a designated location for subsequent reprocessing. At the same time, the shut-off valve can conveniently control the opening and closing of the vertical pipe.

[0014] Specifically, the connection between the ring pipe seat and the main body of the pretreatment equipment and the connection between the pipe sleeve and the corrugated pipe are both equipped with protective grating plates.

[0015] By adopting the above technical solution, the grating plate can provide auxiliary protection for the structure in the ring pipe seat and the pipe sleeve, enabling it to operate more stably.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of the pretreatment equipment body, ring pipe seat, check valve and turbine fan, enables the turbine fan in the ring pipe seat on the outer periphery of the pretreatment equipment body to operate and draw air from the equipment when the sludge is dried to a certain extent during the use of the sludge solidification pretreatment equipment for environmental remediation. This allows the odor carried in the air to be guided and discharged to a designated location, thereby reducing the impact caused by direct odor emission and enabling the pretreatment equipment to pretreat the sludge more stably.

[0018] 2. The technical solution of this application, through the design of the sleeve, cross ring seat, filter plate and activated carbon plate, allows the gas to be easily drawn into the sleeve when the turbine fan draws gas from the main body of the pretreatment equipment. This enables the filter plate and activated carbon plate in the cross ring seat inside the sleeve to filter and purify the drawn gas to a certain extent, facilitating the pretreatment of the air and odors. This makes it easier to process the air more stably and discharge it stably. At the same time, the sleeve is easy to disassemble and replace, making it convenient to disassemble and replace the internal structure of the sleeve. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3This utility model provides a technical solution: a sludge solidification pretreatment device for environmental remediation, comprising a frame 1, a pretreatment equipment body 2 for sludge solidification is mounted inside the frame 1, and a ring pipe seat 3 for support is mounted on the outer peripheral surface of the pretreatment equipment body 2, a turbine fan for air extraction is mounted inside the ring pipe seat 3, and check valves 16 located on both sides of the turbine fan 4 are mounted on the inner side of the ring pipe seat 3; a pipe sleeve 5 for support is screwed onto the end of the ring pipe seat 3 away from the pretreatment equipment body 2, and a cross ring seat 6 for support is screwed onto the pipe sleeve 5, and an activated carbon plate 7 and a filter screen plate 8 for filtration are mounted inside the cross ring seat 6.

[0026] When in use, during the process of using the sludge solidification pretreatment equipment for environmental remediation, when the sludge is dried to a certain extent, the turbine fan 4 in the outer ring pipe seat 3 of the pretreatment equipment body 2 will operate and draw air from the equipment, so that the odor carried in the air can be guided and discharged to the designated location, thereby reducing the impact caused by the direct emission of odor, and enabling the pretreatment equipment to pretreat the sludge more stably.

[0027] When the turbine fan 4 extracts the gas from the main body 2 of the pretreatment equipment, it can easily enter the sleeve 5, so that the filter plate 8 and activated carbon plate 7 in the cross ring seat 6 inside the sleeve 5 can filter and purify the extracted gas to a certain extent, which facilitates the pretreatment of the air and the odors therein, thus making it easier to process it more stably in the future and to discharge it stably. At the same time, the sleeve 5 is easy to disassemble and install, and it is easy to disassemble and replace the internal structure of the sleeve 5.

[0028] like Figure 2 and Figure 3 As shown, the inner side of the sleeve 5 is fitted with a filter cotton core 9 that abuts against the cross ring seat 6.

[0029] When in use, the filter cotton core 9 in the sleeve 5 can be used in conjunction with the activated carbon plate 7 and the filter screen plate 8 to facilitate the filtration of the extracted air and odors, thereby improving the pretreatment effect and making subsequent treatment more convenient.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a vertical pipe 11 for support is assembled inside the frame 1, and a bend 12 for flow guidance is rotatably installed at the end of the vertical pipe 11 away from the frame 1. A corrugated pipe 13 for flow guidance is assembled between the bend 12 and the sleeve 5.

[0031] In use, the corrugated pipe 13 facilitates the flow of pre-filtered air and allows it to enter the vertical pipe 11 through the bend 12, so that the pre-treated air and odors can be discharged to the designated location.

[0032] like Figure 1 and Figure 2 As shown, a shut-off valve 15 connected to the vertical pipe 11 is mounted on the top surface of the frame 1, and a fan 14 connected to the shut-off valve 15 is mounted on the top surface of the frame 1.

[0033] When in use, the blower 14 is convenient to assist in drawing gas into the vertical pipe 11, and the outlet of the blower 14 can be connected to the external exhaust pipe, so that the gas after preliminary filtration can be discharged to a designated location for subsequent reprocessing. At the same time, the shut-off valve 15 facilitates the opening and closing of the vertical pipe 11.

[0034] like Figure 2 and Figure 3 As shown, the connection between the ring pipe seat 3 and the pretreatment equipment body 2 and the connection between the pipe sleeve 5 and the corrugated pipe 13 are both equipped with protective grating plates 10.

[0035] When in use, the grating plate 10 provides auxiliary protection for the structure in the ring pipe seat 3 and the pipe sleeve 5, enabling it to operate more stably.

[0036] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in suitable positions. During the use of the sludge solidification pretreatment equipment for environmental remediation, when the sludge has dried to a certain extent, the turbine fan 4 in the outer ring pipe seat 3 of the pretreatment equipment body 2 operates and extracts air from the equipment. This allows odors carried in the air to be guided and discharged to a designated location, thereby reducing the impact of direct odor emissions. This enables the pretreatment equipment to more stably pretreat the sludge. Simultaneously, when the turbine fan 4 extracts gas from the pretreatment equipment body 2, the extracted gas easily enters the pipe sleeve 5. The filter plate 8 and activated carbon plate 7 in the cross ring seat 6 inside the pipe sleeve 5 can filter and purify the extracted gas to a certain extent, facilitating... The air and its odors are pre-treated to facilitate more stable subsequent treatment and discharge. The sleeve 5 is easy to disassemble and replace, and the filter cotton core 9 within it works in conjunction with the activated carbon plate 7 and filter screen 8 to further filter the extracted air and odors, improving the pre-treatment effect and making subsequent treatment more convenient. It also enables the operation of the fan 14 at the top of the frame 1, which helps to draw gas into the vertical pipe 11. The outlet of the fan 14 can be connected to an external exhaust pipe, allowing the pre-filtered gas to be discharged to a designated location for further treatment. This ensures that the pre-treatment equipment can more stably treat the sludge.
