Abstract
Description
Technical Field
[0001] This utility model relates to the field of mortar production technology, specifically to a tailings sand screening device for dry-mixed mortar production. Background Technology
[0002] In the production and processing of dry-mixed mortar, sand and gravel of different sizes need to be added to facilitate the mixing of different sizes of materials. When utilizing tailings sand, since it contains gravel particles of various sizes, it needs to be screened to remove larger particles that do not meet the requirements. The common screening method is usually a reciprocating vibrating screen.
[0003] However, in actual use, reciprocating vibrating screens can cause larger particles such as stones to clog the surface of the screen, resulting in lower screening efficiency during subsequent processing. Manual cleaning is also inconvenient. In addition, different sizes and types of screens need to be replaced for different screening needs. Traditional screening devices usually have fixed screen structures, which means that multiple bolts and other fixing objects need to be removed to remove the device for cleaning or replacement, which is very inconvenient. Utility Model Content
[0004] The purpose of this invention is to provide a tailings sand screening device for dry-mixed mortar production, which solves the problems of inconvenient replacement, inconvenient cleaning, and easy clogging in existing devices.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tailings sand screening device for dry-mixed mortar production, including a rotating cylinder, a screening cylinder is provided at the center of the rotating cylinder, multiple screening plates are arranged around the outer wall of the rotating cylinder, a driving component is installed at one end of the outer wall of the rotating cylinder, a fixing rod is installed at the top of the rotating cylinder, and a cleaning roller is provided at the top of the inner part of the rotating cylinder.
[0006] A fixed plate is rotatably connected to one side of the rotating cylinder, and a closed ring is arranged around the inside of the end of the rotating cylinder away from the fixed plate. The outer wall of one end of the screening cylinder is fixedly connected to the rotating cylinder through the closed ring.
[0007] The outer wall of the rotating cylinder is provided with slide rails on both sides near the screening plate, and both sides of the screening plate are slidably connected to the inside of the slide rails.
[0008] The drive assembly includes a driven gear ring, which is fixedly connected to the outer wall of the rotating cylinder, and a rotating wheel is meshed at the bottom end of the driven gear ring.
[0009] Preferably, one end of the rotating cylinder is rotatably connected to the side wall of the fixed plate via a rotating shaft, and rectangular holes are provided at corresponding positions on the side wall of the rotating cylinder and the screening plate, with both sides of the inner wall of the rectangular holes being inclined.
[0010] Preferably, one end of the screening cylinder is rotatably connected to the fixed plate via a rotating shaft, the internal pores of the screening cylinder are larger than the internal pores of the screening plate, and a feeding pipe is provided at the center of the screening cylinder, with one end of the feeding pipe close to the side of the fixed plate.
[0011] Preferably, a drive motor is installed on the side wall of the fixed plate at a position corresponding to the rotating wheel, and the output end of the drive motor is fixedly connected to the rotating wheel.
[0012] Preferably, the top of the cleaning roller is attached to the side of the screening plate near the rotating cylinder, and a rotating motor is installed at one end of the cleaning roller through the interior of the fixed plate.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0016] 1. The cleaning roller can clean the inner wall of the screening plate when it rotates to the top position, effectively removing the sand and gravel particles that clog it. At the same time, when the rotating drum rotates, it can effectively drive the screening plate and slide rail on the outer wall to rotate, so that the slide rail and screening plate intermittently contact the top striking rod, which can effectively drive the striking rod to move back and forth, thereby achieving knocking vibration on the outer wall of the rotating drum. This can further vibrate and clean the top of the screening plate, thereby vibrating away the blockage. In this way, the device can effectively remove particle blockage and improve filtration efficiency.
[0017] 2. Rotate the screen plate that needs to be replaced to the top position, and then rotate the fixing bolts to release the pressure of the fixing bolts on the outer wall of the rotating cylinder. This allows the screen plate to be easily moved along both sides of the slide rail by pulling the plate, thereby disconnecting it from the rotating cylinder. This makes replacement and cleaning convenient and quick. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] This utility model provides, for example Figure 1-5 The device shown is a tailings sand screening device for dry-mixed mortar production. It includes a rotating cylinder 1, a screening cylinder 2 at its center, multiple screening plates 3 surrounding the outer wall of the rotating cylinder 1, a drive assembly 4 installed at one end of the outer wall of the rotating cylinder 1, a fixed rod 5 installed at the top of the rotating cylinder 1, and a cleaning roller 7 at the top of the inner part of the rotating cylinder 1. A fixed plate 6 is rotatably connected to one side of the rotating cylinder 1, and a closed ring 202 surrounds the inner part of the rotating cylinder 1 away from the fixed plate 6. One end of the outer wall of the screening cylinder 2 is fixedly connected to the rotating cylinder 1 via the closed ring 202. Slide rails 102 are provided on both sides of the outer wall of the rotating cylinder 1 near the screening plates 3, and both sides of the screening plates 3 are slidably connected to the slide rails 102. The drive assembly 4 includes a driven gear ring 401, which is fixedly connected to the outer wall of the rotating cylinder 1, and a rotating wheel 402 is meshed with the bottom end of the driven gear ring 401.
[0028] The material is initially screened and filtered by the screening cylinder 2, causing it to fall into the rotating cylinder 1. As the rotating cylinder 1 rotates, the material moves to the screening plate 3 for further screening and filtration. The rotation of the rotating motor 701 causes the cleaning roller 7 to rotate, cleaning the inner wall of the screening plate 3 at the top position, effectively removing clogged sand and gravel particles. The striking rod 501 vibrates the outer wall of the rotating cylinder 1, further vibrating and cleaning the top of the screening plate 3, thus removing blockages. The device effectively removes particle blockages and improves filtration efficiency. Rotating the fixing bolt 302 releases the pressure of the fixing bolt on the outer wall of the rotating cylinder 1, allowing the screening plate 3 to move along both sides of the slide rail 102 via the moving pull plate 301, thus disconnecting the screening plate 3 from the rotating cylinder 1, enabling replacement and cleaning of the screening plate 3.
[0029] like Figure 2 , Figure 5 As shown, one end of the rotating cylinder 1 is rotatably connected to the side wall of the fixed plate 6 via a rotating shaft. Rectangular holes 101 are provided at corresponding positions on the side wall of the rotating cylinder 1 and the screening plate 3. The inner walls of the rectangular holes 101 are inclined on both sides. A pulling plate 301 is provided on the outer wall of the end of the screening plate 3 away from the fixed plate 6. A fixing bolt 302 is threaded inside the pulling plate 301. One end of the fixing bolt 302 passes through the interior of the pulling plate 301 and is pressed against the outer wall of the rotating cylinder 1. Rotating the fixing bolt 302 releases the pressure of the fixing bolt 302 on the outer wall of the rotating cylinder 1. Thus, the screening plate 3 can be easily moved along both sides of the slide rail 102 by moving the pulling plate 301, thereby disconnecting the screening plate 3 from the rotating cylinder 1. This allows for the replacement and cleaning of the screening plate 3, making the operation convenient and quick.
[0030] like Figure 3 , Figure 4 As shown, one end of the screening cylinder 2 is rotatably connected to the fixed plate 6 via a rotating shaft. The internal pores of the screening cylinder 2 are larger than those of the screening plate 3. A feeding pipe 201 is provided at the center of the screening cylinder 2. One end of the feeding pipe 201 is close to the side of the fixed plate 6. The rotating cylinder 1 drives the screening cylinder 2 to rotate through the closed ring 202, so that the material can be initially screened and filtered by the screening cylinder 2, causing the material to fall into the interior of the rotating cylinder 1. Then, the material moves into the interior of the screening plate 3 as the rotating cylinder 1 rotates, thereby achieving secondary screening and filtration.
[0031] like Figure 1 , Figure 2As shown, a drive motor 403 is installed on the side wall of the fixed plate 6 at the position corresponding to the rotating wheel 402. The output end of the drive motor 403 is fixedly connected to the rotating wheel 402. When the drive assembly 4 is started, the drive motor 403 drives the driven gear ring 401 to rotate through the rotating wheel 402, which in turn drives the rotating cylinder 1 to rotate. The rotating cylinder 1 then drives the screening cylinder 2 to rotate through the closed ring 202.
[0032] like Figure 2 , Figure 3 As shown, the top of the cleaning roller 7 is attached to the side of the screening plate 3 near the rotating cylinder 1. One end of the cleaning roller 7 is installed inside the fixed plate 6 with a rotating motor 701. When the rotating motor 701 is started, the cleaning roller 7 rotates, which in turn allows the cleaning roller 7 to clean the inner wall of the screening plate 3 that has rotated to the top position, effectively removing the blocked sand and gravel particles.
[0033] like Figure 1 , Figure 2 As shown, multiple striking rods 501 are rotatably connected to the outer wall of the fixed rod 5. One side of the striking rod 501 is inclined and fits against the outer wall of the rotating cylinder 1. When the rotating cylinder 1 rotates, it can effectively drive the screening plate 3 and the slide rail 102 on the outer wall to rotate, thereby causing the slide rail 102 and the screening plate 3 to intermittently contact the striking rod 501 at the top, which can effectively drive the striking rod 501 to move back and forth, thereby realizing the striking rod 501 striking and vibrating the outer wall of the rotating cylinder 1, which can further vibrate and clean the top of the screening plate 3, thereby vibrating and clearing the blockage, and thus the device can effectively remove particle blockage.
[0034] In use, materials can be easily conveyed into the screening cylinder 2 through the feeding pipe 201. The drive assembly 4 is started, which causes the drive motor 403 to drive the driven gear ring 401 to rotate through the rotating wheel 402, which in turn causes the rotating cylinder 1 to rotate. The rotating cylinder 1 then drives the screening cylinder 2 to rotate through the closed ring 202, so that the material can be initially screened and filtered by the screening cylinder 2. The material falls into the interior of the rotating cylinder 1, and then moves into the interior of the screening plate 3 as the rotating cylinder 1 rotates, thereby achieving secondary screening and filtration.
[0035] During use, large particles are filtered through the relatively large-slit screening cylinder 2 and discharged through one end of the screening cylinder 2. Starting the rotating motor 701 causes the cleaning roller 7 to rotate, which in turn cleans the inner wall of the screening plate 3 at the top position, effectively removing clogged sand and gravel particles. Simultaneously, as the rotating cylinder 1 rotates, it effectively drives the outer wall screening plate 3 and slide rail 102 to rotate, causing the slide rail 102 and screening plate 3 to intermittently contact the top striking rod 501. This effectively drives the striking rod 501 to move back and forth, thus causing the striking rod 501 to vibrate and strike the outer wall of the rotating cylinder 1, further vibrating and cleaning the top of the screening plate 3, thereby removing the blockage. Therefore, the device effectively removes particle blockage and improves filtration efficiency.
[0036] When the screening plate 3 needs to be replaced, the corresponding screening plate 3 to be replaced can be easily rotated to the top position, and then the fixing bolt 302 can be rotated to release the pressure of the fixing bolt 302 on the outer wall of the rotating cylinder 1. Then, the screening plate 3 can be easily moved along both sides of the slide rail 102 by the movement of the pulling plate 301, thereby disconnecting the screening plate 3 from the rotating cylinder 1, thus realizing the replacement and cleaning of the screening plate 3. The operation is convenient and quick.
[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
