Description
Technical Field
[0001] This utility model relates to the field of sludge backfill agent production technology, specifically to a discharge filtration device for producing sludge backfill agent. Background Technology
[0002] In the field of environmental protection industry and solid waste resource utilization, sludge backfilling agent is a key product for realizing sludge reduction, harmlessness and resource utilization. Its production quality directly affects the stability and environmental performance in subsequent engineering applications. In the industrial production process of sludge backfilling agent, the filtration of liquid finished product is the core process to ensure product purity. It is necessary to remove unreacted solid particles, impurities and flocculents left over from the production process through filtration to avoid such substances causing pipe blockage, reducing the density of backfill body or causing secondary environmental pollution risks during subsequent backfilling construction. Currently, filtration devices for liquid sludge backfilling agents in the industry generally suffer from the following technical challenges: Existing filtration devices mostly rely on the principle of static filtration, which uses gravity to allow liquid materials to naturally permeate the filter medium to achieve solid-liquid separation. During static filtration, the material flow rate is slow and a filter cake layer is easily formed on the surface of the filter medium, resulting in a continuous increase in filtration resistance and low filtration efficiency. Traditional filtration devices typically have closed or semi-closed filter chambers with smooth, flat inner walls. During filtration, sticky materials tend to adhere to the inner walls and bottom corners of the chamber. Especially in the later stages of filtration, some impurities that have not passed through the filter medium will settle at the bottom of the chamber with the material flow, forming a difficult-to-clean residue layer that cannot be easily cleaned and affects the quality of subsequent sludge backfill. Therefore, it is necessary to design a discharge filtration device for producing sludge backfill material to solve the above problems. Utility Model Content

A first hydraulic cylinder is fixedly connected to the right side of the connecting frame, and a protective box is fixedly connected to the left side of the first hydraulic cylinder.

A feeding pipe is fixedly connected to the bottom right side of the protective box, and the servo motor and the feeding pipe are slidably connected inside the fixed platform, so as to facilitate the rotation of the mounting frame and filter frame by rotating the rotating rod.
[0007] Preferably, connecting arms are fixedly connected to the top of the left and right sides of the filter frame, and the connecting arms are slidably connected to the outer periphery of the top of the protective box, so as to ensure the stability of the filter frame during operation.
[0008] Preferably, the outer left side and bottom of the scraper are in contact with the inner side and bottom of the protective box, respectively, so that the inner side of the protective box can be cleaned by the scraper, and at the same time, it can help improve the efficiency of the backfilling agent after filtration.
[0009] Preferably, the feeding mechanism includes a base, which is fixedly connected to the top left side of the fixed platform. A storage box is fixedly connected to the top of the base, and a conveying pipe is fixedly connected to the bottom right side of the storage box.

A sealing plate is fixedly connected to the bottom of the second hydraulic cylinder, and the sealing plate is slidably connected inside the conveying pipe.
[0010] Preferably, the bottom of both the storage tank and the conveying pipe are inclined, and the conveying pipe is located at the top of the protective box, which facilitates the conveying of the produced liquid sludge backfill agent into the protective box for filtration.
[0011] Compared with the prior art, this utility model provides a discharge filtration device for producing sludge backfilling agent, which has the following beneficial effects: 1. This sludge backfill material discharge filtration device, through its filtration mechanism, allows for the filtration of the liquid sludge backfill material after production. First, the filter frame is slidably connected to the inside of the protective box and inserted into the top of the mounting frame. As the filter frame moves, the connecting arm slides to the outer edge of the top of the protective box, thus ensuring the installation of the filter frame and maintaining stability during operation. This also facilitates removal and cleaning after filtration. Subsequently, the first hydraulic cylinder drives the protective box to slide between the top of the fixed platform and the support plate, moving it to the bottom of the conveying pipe. Then, the material is discharged through the external... The collection pipe is connected to the discharge pipe. When the sludge backfill material is transported through the conveying pipe to the inside of the filter frame in the protective box, the servo motor drives the rotating rod to rotate the mounting frame and filter frame at high speed. Centrifugal force is used to accelerate the separation of materials and impurities in the sludge backfill material, which improves the filtration efficiency compared to static filtration. At the same time, the scraper on the outside of the rotating rod rotates synchronously with the rotating rod. Its left outer edge and bottom are in close contact with the inside and bottom of the protective box, respectively, which can scrape off the filter residue material attached to the inner wall and bottom of the protective box in real time. At the same time, it can assist in the discharge process and improve efficiency.
[0012] 2. This discharge filtration device for producing sludge backfill material, through its feeding mechanism, allows for the filtration of liquid sludge backfill material after production. First, the sludge backfill material is fed into the storage tank and then into the conveying pipe. By controlling the stroke of the second hydraulic cylinder, the upward distance of the sealing plate within the conveying pipe can be adjusted, thereby regulating the feeding amount and speed. This prevents excessive material input from overloading the filter frame and improves the filtration effect. Both the storage tank and the bottom of the conveying pipe are inclined, utilizing gravity to achieve natural material guidance and conveying without the need for additional power to drive the material flow, while also preventing material blockage.

[0024] In actual operation, when this device is used, when it is necessary to filter the liquid sludge backfill agent after production, firstly, the filter frame 293 is slidably connected to the inside of the protective box 25 and inserted into the top of the mounting frame 292.

When the sludge backfill material conveyed through the conveying pipe 33 is delivered to the inside of the filter frame 293 in the protective box 25, the servo motor 26 drives the rotating rod 29 to drive the mounting frame 292 and the filter frame 293 to rotate at high speed. Centrifugal force is used to accelerate the separation of materials and impurities in the sludge backfill material, which improves the filtration efficiency compared with static filtration. At the same time, the scraper 291 on the periphery of the rotating rod 29 rotates synchronously with the rotating rod 29. Its left periphery and bottom are in close contact with the inside and bottom of the protective box 25, respectively, which can scrape off the filter residue material attached to the inner wall and bottom of the protective box 25 in real time. At the same time, it can assist in the feeding process and improve efficiency. The filtered sludge backfill material will be discharged through the feeding pipe 27. After filtration is complete, the protective box 25 can be moved to the right by the action of the first hydraulic cylinder 24, and the staff can take out the filter frame 293 to clean the impurities inside.
