Description

Technical Field

[0001] This utility model relates to the field of work technology, and in particular to a waste concrete separation device for concrete processing. Background Technology

[0002] Against the backdrop of rapid development in the construction industry, the resource-based treatment of waste concrete has become a key link in the sustainable development of the industry. Waste concrete separation equipment separates aggregates, cement paste and other components from waste concrete through core processes such as screening and crushing, realizing the recycling of sand and gravel aggregates and the recovery of slurry, effectively reducing resource waste and environmental pollution. Among them, the screen, as the core component of the separation equipment responsible for material classification and screening, directly determines the screening accuracy and separation efficiency of aggregate particle size.

[0003] To ensure the stability of the screen under high-intensity vibration and material impact conditions, most waste concrete separation equipment uses welding to fix the screen to the inner wall of the separation box. While this installation method can ensure the structural stability of the equipment in the early stages of operation, it has significant drawbacks in screen maintenance. Due to the complex composition of waste concrete, the inclusion of sand, gravel, metal fragments, and other materials can easily cause localized wear and mesh blockage of the screen, requiring regular cleaning or replacement. However, the welded screen needs to be forcibly removed with tools such as angle grinders during maintenance. This process is not only cumbersome and time-consuming, but the high temperature and mechanical stress generated during cutting can easily damage the metal structure of the separation box, causing deformation of the box or cracking of the welded parts. This significantly increases the difficulty and cost of equipment repair. At the same time, long-term downtime for screen replacement interrupts the continuous waste concrete processing flow, reduces equipment utilization, and fails to meet the demand for efficient operation and maintenance in industrial production. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a waste concrete separation device for concrete processing. This device solves the problem of fixing the screen to the inner wall of the separation box by welding. Although this installation method can ensure the structural stability of the equipment in the early stage of operation, it has significant drawbacks in the screen maintenance process. Due to the complex composition of waste concrete, the sand, gravel, metal debris and other materials mixed in can easily cause local wear and mesh blockage of the screen, requiring regular cleaning or replacement. When maintaining the welded screen, tools such as angle grinders are needed to forcibly remove it. This is not only cumbersome and time-consuming, but the high temperature and mechanical stress generated during the cutting process can easily damage the metal structure of the separation box, causing deformation of the box or cracking of the welded parts. This greatly increases the difficulty and cost of equipment maintenance. At the same time, long-term downtime for screen replacement will interrupt the continuous processing of waste concrete, reduce equipment utilization, and fail to meet the needs of industrial production for efficient operation and maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste concrete separation device for concrete processing, comprising a separation box, a feeding plate and a discharging plate, wherein a limit component is provided on the separation box;

[0006] The limiting assembly includes a mounting base, a screen, and two protective shells. Both protective shells are fixedly connected to the outer wall of the separation box. The feed plate is fixedly installed at the upper feed port of the separation box, and the discharge plate is fixedly installed at the lower discharge port on one side of the separation box. The screen is fixedly connected to the outer wall of the mounting base. A second limiting block groove is opened on the outer wall of the opposite side of the two protective shells. A limiting block is slidably connected inside the two second limiting block grooves.

[0007] The mounting base has a first limiting plate groove on both sides of its outer wall, three sliding rods are slidably connected to the upper outer wall of both mounting bases, push block grooves are opened on both sides of its outer wall, a return spring is sleeved on the outer wall of each of the six sliding rods, push blocks are slidably connected inside the two sets of push block grooves, and rubber limiting blocks are set inside the two sets of push block grooves.

[0008] Preferably, the outer wall of the screen is slidably connected to the lower outer wall of the separation box by an inclined groove, and the screen is arranged at an inclination.

[0009] In this configuration, the ends of the two limiting blocks near the first limiting plate groove both slide to the outside of the second limiting block groove and are respectively slidably connected to the inside of the corresponding first limiting plate groove.

[0010] Preferably, the ends of the six slide rods near the limiting block all slide into the interior of the second limiting block groove and are respectively fixedly connected to the outer wall of the corresponding limiting block;

[0011] The four push block slots are arranged in pairs, and the interior of each pair of push block slots is connected to the interior of the corresponding second limit block slot.

[0012] Preferably, the ends of the four push blocks near the limiting blocks all slide into the interior of the second limiting block groove and are fixedly connected to the outer wall of the corresponding limiting blocks.

[0013] Preferably, the two ends of the four rubber limiting blocks are in contact with the outer wall of the corresponding push block and the inner wall of the push block groove, respectively;

[0014] The two ends of the six reset springs are fixedly connected to the outer wall of the corresponding limit block and the inner wall of the second limit block groove, respectively.

[0015] Preferably, a sieve cylinder is fixedly connected to the upper end of the separation box, a motor is fixedly connected to the outer wall of a fixed plate on one side of the separation box, and a spiral stirring shaft is rotatably connected to the upper end of the separation box, with the spiral stirring shaft located inside the sieve cylinder.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This waste concrete separation equipment for concrete processing uses a pusher block in the limiting component to push the limiting block, which in turn drives the limiting block to overcome the elastic force of the reset spring and slide out from the first limiting plate groove of the mounting seat, releasing the limitation on the mounting seat. At this time, the mounting seat and the screen can be pulled out from the inclined groove at the bottom of the separation box for cleaning or replacement. This makes the screen disassembly simple and quick, avoiding the need for workers to use tools such as angle grinders to forcibly remove it, effectively improving the screen disassembly efficiency while reducing the workload of workers.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a waste concrete separation device for concrete processing, including a separation box 1, a feeding plate 11 and a discharging plate 12;

[0030] Limiting components are provided on separation box 1;

[0031] The limiting assembly includes a mounting base 3, a screen 9, and two protective shells 4. Both protective shells 4 are fixedly connected to the outer wall of the separation chamber 1. A feed plate 11 is fixedly installed at the upper feed inlet of the separation chamber 1, and a discharge plate 12 is fixedly installed at the lower discharge outlet of the separation chamber 1. A screen 9 is fixedly connected to the outer wall of the mounting base 3. The outer wall of the screen 9 is slidably connected to the lower outer wall of the separation chamber 1 through an inclined groove. The screen 9 is arranged at an angle. A second limiting block groove 17 is provided on the opposite side of the outer wall of each of the two protective shells 4. Limiting blocks 16 are slidably connected inside the two second limiting block grooves 17. First limiting plate grooves 13 are provided on both sides of the outer wall of the mounting base 3. The ends of the two limiting blocks 16 closest to the first limiting plate grooves 13 slidably extend to the outside of the second limiting block grooves 17 and are slidably connected to the interior of the corresponding first limiting plate grooves 13. Three sliding rods 5 are slidably connected to the upper outer wall of each of the two mounting bases 3. Each slide rod 5 extends slidably into the interior of the second limit block groove 17 at one end near the limit block 16 and is fixedly connected to the outer wall of the corresponding limit block 16. Push block grooves 8 are provided on the outer walls of both sides of the two mounting bases 3. The four push block grooves 8 are in groups of two. The interiors of the two groups of push block grooves 8 are respectively connected to the interiors of the corresponding second limit block grooves 17. Each slide rod 5 has a return spring 18 sleeved on its outer wall. Push blocks 7 are slidably connected inside the two groups of push block grooves 8. Each push block 7 extends slidably into the interior of the second limit block groove 17 at one end near the limit block 16 and is fixedly connected to the outer wall of the corresponding limit block 16. Each push block groove 8 has a rubber limit block 6 inside. The two ends of the four rubber limit blocks 6 are respectively in contact with the outer wall of the corresponding push block 7 and the inner wall of the push block groove 8. The two ends of the six return springs 18 are respectively fixedly connected to the outer wall of the corresponding limit block 16 and the inner wall of the second limit block groove 17.

[0032] The upper end of the separation box 1 is fixedly connected to a sieve cylinder 10. A motor 15 is fixedly connected to the outer wall of a fixed plate on one side of the separation box 1. A spiral stirring shaft 14 is rotatably connected to the upper end of the separation box 1. The spiral stirring shaft 14 is located inside the sieve cylinder 10. The output end of the motor 15 extends rotatably into the interior of the separation box 1 and is fixedly connected to one end of the spiral stirring shaft 14. A collection box 2 is slidably connected to the lower end of the separation box 1.

[0033] Furthermore, when using this device, waste concrete is poured into the separation box 1 from the feed plate 11. At this time, the motor 15 starts, and its output end drives the spiral stirring shaft 14 to rotate inside the screen cylinder 10. When the spiral stirring shaft 14 rotates, the waste concrete moves inside the screen cylinder 10 through stirring and pushing. Smaller particles pass through the screen holes of the screen cylinder 10 and fall to the bottom of the separation box 1, while larger particles continue to be stirred and pushed inside the screen cylinder 10. At the bottom of the separation box 1, the screen 9 on the mounting base 3 receives the material falling from the screen cylinder 10. The screen 9 is arranged at an inclination, and smaller particles pass through the screen 9 and enter the interior of the collection box 2 for further separation. Larger particles move downward along the screen 9 under the action of gravity. The screen 9 slides out through the discharge plate 12 and is then connected to the separation box 1 via a limiting component. When the screen 9 needs to be cleaned or replaced, pull the handle on the rubber limiting block 6 to remove it from the inside of the push block groove 8. Then push the push block 7, which drives the limiting block 16 to overcome the elastic force of the return spring 18 and slide out from the first limiting plate groove 13 of the mounting seat 3, releasing the limitation on the mounting seat 3. At this time, the mounting seat 3 along with the screen 9 can be pulled out from the inclined groove at the lower end of the separation box 1 for cleaning or replacement. After cleaning or replacement, reinsert the mounting seat 3 into the inclined groove of the separation box 1, release the push block 7, and the return spring 18 pushes the limiting block 16 back into the first limiting plate groove 13 to fix the screen 9 and continue the separation work.

[0034] By pushing the pusher 7 through the limiting component, the pusher 7 drives the limiting block 16 to overcome the elastic force of the reset spring 18 and slide out from the first limiting plate groove 13 of the mounting base 3, releasing the limitation on the mounting base 3. At this time, the mounting base 3 together with the screen 9 can be pulled out from the inclined groove at the lower end of the separation box 1 for cleaning or replacement. This makes disassembling the screen 9 simple and quick, avoiding the need for workers to use tools such as angle grinders to forcibly remove it, effectively improving the disassembly efficiency of the screen 9 while reducing the workload of workers.
