Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a screening device for paving brick raw materials. Background Technology

[0002] In the production process of paving bricks (such as permeable bricks), to enhance their aesthetics and functionality, a layer of sand and cement of a specific particle size is usually laid on the surface as a finishing material. This surface material must meet the requirements of uniform moisture content and clean texture to ensure the aesthetics, permeability, and anti-slip performance of the paving brick surface.

[0003] Currently, the sand used in the production of this type of surface layer suffers from problems due to the inability to precisely control the moisture content of the raw materials. Cement or fine sand absorbs moisture from the air during storage, and even if it appears dry, trace amounts of moisture are enough to initiate the initial hydration reaction on the surface of the cement particles, leading to clumping of some of the surface material. Therefore, after mixing the sand and cement for this type of surface layer, a screening device is required. While existing screening devices can separate the clumps, these clumps typically require collection equipment and further dispersing, resulting in low efficiency. Utility Model Content

[0004] In order to overcome the problem that existing screening devices can screen out clumps of fabric, but after screening, the clumps of fabric usually need to be collected by corresponding collection equipment and then broken up, resulting in low efficiency, this utility model proposes a screening device that can directly crush the screened clumps of paving brick raw materials.

[0005] To achieve the above objectives, this utility model provides a screening device for paving brick raw materials:

[0006] It includes a screen cylinder, with a conveying cylinder and a receiving cylinder at each end. A guide frame is fixed and connected to the bottom of the receiving cylinder. Two baffles are symmetrically fixed at the bottom of the guide frame, and an arc-shaped plate is disposed between the two baffles. The two sides of the arc-shaped plate are respectively attached to the two baffles. A rotating shaft is rotatably connected between the two baffles. A crushing disc is fixed to the outside of the rotating shaft. Multiple arc-shaped plates are disposed on the outside of the crushing disc. Multiple second crushing columns are fixed to the outside of the arc-shaped plates. Multiple... The first crushing column has a material collection cavity between the arc plate and the crushing disc, and the width of the material collection cavity gradually decreases from top to bottom. The conveying cylinder and the receiving cylinder are rotatably connected to a rotating rod. Multiple supports are fixed on the outside of the rotating rod. The end of the support away from the rotating rod is fixed to the inner wall of the screen cylinder. A drive gear is fixed on the end of the rotating rod extending outside the receiving cylinder. A driven gear is fixed on the end of the rotating shaft extending outside the baffle. Internal toothed belts are provided on the outside of the drive gear and the driven gear, and both the drive gear and the driven gear mesh with the internal toothed belts.

[0007] Preferably, a triangular plate is fixed to the inner wall of the guide frame, and a feeding cavity is formed between the triangular plate and the inner wall of the guide frame. The feeding cavity and the collecting cavity are connected.

[0008] Preferably, a rectangular plate is fixed to the top of the arc-shaped plate, and a first screw passes through the rectangular plate and is threadedly connected to the guide frame.

[0009] Preferably, each of the four corners of the arc-shaped plate has a round hole, and a second screw passes through the round hole. Multiple screw holes are provided on the outer side of the rolling disc, and the second screw is threadedly connected to the screw holes.

[0010] Preferably, the diameter of the conveying cylinder is smaller than the diameter of the screen cylinder, one end of the conveying cylinder extends into the screen cylinder and the conveying cylinder and the screen cylinder are connected, the diameter of the receiving cylinder is larger than the diameter of the screen cylinder, the end of the screen cylinder away from the conveying cylinder extends into the receiving cylinder and the conveying cylinder and the receiving cylinder are connected, a motor is installed on one side of the conveying cylinder, and the end of the rotating rod extending outside the conveying cylinder is fixed to the output end of the motor.

[0011] Preferably, a feeding hopper is fixed and connected above the feeding cylinder, two first legs are symmetrically fixed below the feeding cylinder, and two second legs are symmetrically fixed below the receiving cylinder, wherein the length of the first legs is greater than the length of the second legs.

[0012] Preferably, two U-shaped connecting plates are symmetrically arranged on the outer side of the screen cylinder. Each U-shaped connecting plate has a mounting plate fixed at both ends. The two mounting plates are fixed to the corresponding conveying cylinder and receiving cylinder respectively by bolts.

[0013] As can be seen from the above technical solution, this application has the following beneficial effects: when the lumps of paving brick raw materials are conveyed into the receiving cylinder, they will fall into the collection chamber. When the rotating rod rotates, it will drive the drive gear to rotate. When the drive gear rotates, it will drive the driven gear and the rotating shaft to rotate through the internal gear belt. When the rotating shaft rotates, it will drive the crushing disc and the arc-shaped plate to rotate. When the arc-shaped plate rotates, under the action of the second crushing column and the first crushing column, the lumps of paving brick raw materials can be crushed. That is, the lumps of paving brick raw materials can be directly crushed and processed without further collection and separate processing. Attached Figure Description

[0022] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0023] Reference Figure 1-7 :

[0024] In one embodiment of this utility model, a screening device for paving brick raw materials is provided, including a screen cylinder 1. A conveying cylinder 2 and a receiving cylinder 3 are respectively provided at both ends of the screen cylinder 1. A guide frame 4 is fixed and connected to the bottom of the receiving cylinder 3. Two baffles 5 are symmetrically fixed at the bottom of the guide frame 4. An arc-shaped plate 6 is provided between the two baffles 5, with its two sides respectively abutting against the two baffles 5. A rotating shaft 9 is rotatably connected between the two baffles 5. A crushing disc 10 is fixed to the outside of the rotating shaft 9. Multiple arc-shaped plates 11 are provided on the outside of the crushing disc 10. Multiple second crushing columns 12 are fixed to the outside of the arc-shaped plates 11. The side of the arc-shaped plate 6 closest to the crushing disc 10... Multiple first crushing columns 7 are fixed. There is a material collection chamber 31 between the arc plate 6 and the crushing disc 10. The width of the material collection chamber 31 gradually decreases from top to bottom. The conveying cylinder 2 and the receiving cylinder 3 are rotatably connected to a rotating rod 18. Multiple supports 19 are fixed on the outside of the rotating rod 18. The end of the support 19 away from the rotating rod 18 is fixed to the inner wall of the screen cylinder 1. The end of the rotating rod 18 extending to the outside of the receiving cylinder 3 is fixed with a driving gear 20. The end of the rotating shaft 9 extending to the outside of the baffle 5 is fixed with a driven gear 21. The driving gear 20 and the driven gear 21 are provided with an internal toothed belt 22 on their outer sides. The driving gear 20 and the driven gear 21 mesh with the internal toothed belt 22.

[0025] The feeding hopper 25 is fixed and connected to the top of the feeding cylinder 2. Two first legs 26 are symmetrically fixed below the feeding cylinder 2. Two second legs 27 are symmetrically fixed below the receiving cylinder 3. The length of the first legs 26 is greater than the length of the second legs 27. The diameter of the feeding cylinder 2 is smaller than the diameter of the screen cylinder 1. One end of the feeding cylinder 2 extends into the screen cylinder 1 and the feeding cylinder 2 and the screen cylinder 1 are connected. The diameter of the receiving cylinder 3 is greater than the diameter of the screen cylinder 1. The end of the screen cylinder 1 away from the feeding cylinder 2 extends into the receiving cylinder 3 and the feeding cylinder 2 and the receiving cylinder 3 are connected. A motor 24 is installed on one side of the feeding cylinder 2. The end of the rotating rod 18 extending outside the feeding cylinder 2 is fixed to the output end of the motor 24. A triangular plate 8 is fixed to the inner wall of the guide frame 4. A discharge chamber 30 is formed between the triangular plate 8 and the inner wall of the guide frame 4. The discharge chamber 30 is connected to the collection chamber 31.

[0026] It should be noted that, since the length of the first support 26 is greater than the length of the second support 27, the screen cylinder 1 is tilted after being placed on the ground, and the position of the conveying cylinder 2 is higher than the position of the receiving cylinder 3. Then, the paving brick raw material to be screened is poured into the feeding hopper 25. Since the diameter of the conveying cylinder 2 is smaller than the diameter of the screen cylinder 1, the paving brick raw material will not overflow when it is conveyed into the screen cylinder 1 through the conveying cylinder 2.

[0027] Furthermore, the motor 24 is started to drive the rotating rod 18 to rotate. When the rotating rod 18 rotates, it drives the screen cylinder 1 to rotate. When the screen cylinder 1 rotates, it screens the paving brick raw materials inside. Since the screen cylinder 1 is set at an inclination, qualified paving brick raw materials pass through the screen cylinder 1, while clumps of paving brick raw materials continue to be conveyed downwards inside the screen cylinder 1. Since the diameter of the receiving cylinder 3 is larger than the diameter of the screen cylinder 1, the clumps of paving brick raw materials will not overflow when they are conveyed from the screen cylinder 1 to the receiving cylinder 3.

[0028] Furthermore, when the clumps of paving brick raw materials are conveyed into the receiving cylinder 3, they will fall from the discharge chamber 30 in the guide frame 4 into the collection chamber 31. When the rotating rod 18 rotates, it will also drive the drive gear 20 to rotate. When the drive gear 20 rotates, it will drive the driven gear 21 to rotate through the internal gear belt 22. When the driven gear 21 rotates, it will drive the rotating shaft 9 to rotate. When the rotating shaft 9 rotates, it will drive the crushing disc 10 and the arc-shaped plate 11 to rotate. At this time, under the action of the second crushing column 12 and the first crushing column 7, the clumps of paving brick raw materials can be crushed. That is, the clumps of paving brick raw materials can be directly crushed and processed without further collection and separate processing.

[0029] In addition, two U-shaped connecting plates 28 are symmetrically arranged on the outside of the screen cylinder 1. Mounting plates 29 are fixed at both ends of the U-shaped connecting plates 28. The two mounting plates 29 are fixed to the corresponding conveying cylinder 2 and receiving cylinder 3 respectively by bolts. The arc-shaped plate 11 has round holes 16 at the four corners. The second screw 17 passes through the round holes 16. Multiple screw holes 15 are opened on the outside of the rolling disc 10. The second screw 17 and the screw holes 15 are threaded together.

[0030] It should be noted that after prolonged use, when the arc plate 6, the first crushing column 7, the arc-shaped piece 11 and the second crushing column 12 show wear, the first screw 14 and the second screw 17 can be removed with the help of a screwdriver or other tools to replace the arc plate 6 and the arc-shaped piece 11.
