Description

Technical Field

[0001] This utility model belongs to the field of colored sand processing technology, and in particular relates to a colored sand sintering cylinder with self-cleaning function. Background Technology

[0002] Sintered colored sand is a type of material made from mineral particles (pebbles) as raw materials, with the addition of inorganic pigments and special coatings, and is prepared by high-temperature sintering. The process of sintering colored sand consists of four steps: stirring, preheating, calcination, and cooling. In the preheating and calcination steps, hot air provided by a hot air furnace is used to preheat and calcine the material in the sintering cylinder. A stirring device is installed in the sintering cylinder to stir and heat at the same time.

[0003] Existing stirring devices typically consist of several stirring rods. The stirring rods rotate inside the sintering cylinder to stir the colored sand inside the cylinder, so that the colored sand is heated more evenly. When the stirring rods stir the colored sand, the colored sand adheres to the outer surface of the stirring rods. At the same time, the colored sand inside the sintering cylinder is only stirred and rotated in one direction by the stirring rods, resulting in low stirring efficiency.

[0004] A search revealed patent number CN220818505U, which provides a colored sand sintering cylinder that effectively solves the problem of agglomeration during the colored sand sintering process. The solution includes a cylindrical cylinder with a stirring unit inside. The stirring unit comprises two rings, eccentrically positioned downwards relative to the cylinder's axis. Multiple stirring components are evenly distributed around the outer circumference of the two rings. Each stirring component includes a straight plate and an arc-shaped plate. The front and rear ends of the straight plate are fixed to the outer walls of the two rings, respectively. The concave surface of the arc-shaped plate faces the cylinder's axis, and one side of the arc-shaped plate is fixed to the outer side of the straight plate. A rotating shaft is located at the axis of each ring, fixed to the ring via a connecting rod. The two rotating shafts are rotatably mounted on the same end face of the cylinder, with one shaft extending through the cylinder and connected to a drive motor. An air inlet pipe is located at the front end of the cylinder, and an air outlet pipe is located at the rear end. This invention provides better stirring effect and can crush agglomerated colored sand, preventing further clumping.

[0005] In the above scheme, when the straight plate and the curved plate are stirring the colored sand in the cylinder, the colored sand is easily attached to the outer surface of the straight plate and the curved plate, and even the colored sand clumps and adheres to the outer surface of the straight plate and the curved plate, which affects the stirring effect. Utility Model Content

[0006] The purpose of this invention is to provide a colored sand sintering cylinder with a self-cleaning function, which has the advantage of cleaning the outer surface of the stirring rod while stirring the colored sand, effectively solving the problem that colored sand easily adheres to the outer surface of the stirring rod during use in the prior art.

[0007] This utility model adopts the following technical solution: a colored sand sintering cylinder with self-cleaning function, including a cylinder body, two annular bodies are coaxially arranged inside the cylinder body, the two annular bodies are symmetrically arranged in the left and right direction, a plurality of stirring rods are arranged in the left and right direction inside the cylinder body, both ends of each stirring rod are fixedly arranged with the two annular bodies, and the outer side of each stirring rod is in contact with the inner sidewall of the cylinder body; a cleaning device is provided on the stirring rod, the cleaning device includes a cleaning part that is slidably arranged on the outer surface of the stirring rod in the left and right direction, the inner side of the stirring rod and two sides perpendicular to the inner side are slidably in contact with the inner sidewall of the cleaning part, the cleaning device also includes a transmission mechanism connected to the cleaning part at the execution end, and a drive mechanism fixedly arranged with the inner sidewall of the cylinder body.

[0008] Furthermore, the cleaning section includes a base plate that slides along the left-right direction with the inner side of the stirring rod, and two sets of side blocks that are fixed to the upper end surface of the base plate by bolts. Two side blocks in each set are fixed by bolts, and both side blocks in each set slide in contact with the outer surface of the stirring rod.

[0009] Furthermore, the transmission mechanism includes a reciprocating screw that is threadedly connected to two side blocks in each group, and both ends of the reciprocating screw are rotatably connected to the stirring rod through a fixed block; both ends of the reciprocating screw are coaxially fixedly provided with gears, and the gears are connected to the output end of the drive mechanism.

[0010] Furthermore, the drive mechanism includes a gear ring fixedly disposed on the inner side wall of the cylinder, and the gear ring meshes with each gear on the corresponding side.

[0011] Furthermore, a rotating shaft is provided inside the cylinder along the left-right direction. The outer surface of the rotating shaft is fixedly connected to each annular body through spokes. Both ends of the rotating shaft are rotatably connected to partitions. The partitions are fixed to the gear ring through cover plates fixed to the outer side of the gear ring. An annular channel is formed between the partitions and the gear ring. Each reciprocating screw is located in the annular channel.

[0012] Furthermore, a motor is fixedly installed on the right side of the cylinder, and the output shaft of the motor is fixedly installed at the right end of the rotating shaft.

[0017] I. This utility model, by setting up a cleaning part, causes the transmission mechanism and the stationary drive mechanism to rotate when the stirring rod rotates the colored sand inside the stirring cylinder, thereby driving the cleaning part to slide left and right on the stirring rod. This achieves the purpose of the cleaning part moving left and right to physically scrape the outer surface of the stirring rod while the stirring rod stirs the colored sand.

[0018] II. This utility model, by setting a reciprocating lead screw, a cleaning part, a gear, and a gear ring, allows the stirring rod to rotate around the axis of the cylinder during use. The stirring rod drives the side block and the reciprocating lead screw to rotate synchronously around the axis of the cylinder, which in turn drives the gear to rotate around the axis of the cylinder. The gear, in conjunction with the stationary drive mechanism, generates its own rotation, that is, the gear rotates around the axis of the reciprocating lead screw, which in turn drives the reciprocating lead screw to rotate around its own axis. The rotation of the reciprocating lead screw drives the side block to move left and right, which in turn causes the side block to drive the scraper to move left and right to scrape and clean the outer surface of the stirring rod.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0031] Please see Figure 1-10 The self-cleaning colored sand sintering cylinder of this utility model includes a cylinder body 1. Two annular bodies 2 are coaxially arranged inside the cylinder body 1, symmetrically arranged in the left-right direction. Several stirring rods 3 are arranged in the left-right direction inside the cylinder body 1. Both ends of each stirring rod 3 are fixed to the two annular bodies 2, and the outer surface of each stirring rod 3 contacts the inner wall of the cylinder body 1. In use, the rotation of the two annular bodies 2 drives the stirring rods 3 to rotate around the axis of the cylinder body 1, causing the stirring rods 3 to stir the colored sand inside the cylinder body 1, resulting in uniform heating of the colored sand and improving the sintering effect of the sintering cylinder. A cleaning device is also provided on the stirring rods 3, including a stirring rod along the left-right direction. The cleaning part 4 is slidably disposed on the outer surface of the stirring rod 3 in the right direction. The inner side and two sides perpendicular to the inner side of the stirring rod 3 are in sliding contact with the inner wall of the cleaning part 4. The cleaning device also includes a transmission mechanism connected to the cleaning part 4 at the execution end, and a drive mechanism fixedly disposed on the inner wall of the cylinder 1. The stirring rod 3 rotates around the axis of the cylinder 1, which drives the transmission mechanism to rotate. This causes the transmission mechanism to rotate in cooperation with the stationary drive mechanism, thereby driving the cleaning part 4 to slide left and right on the stirring rod 3. This allows the inner wall of the cleaning part 4 to clean the outer surface of the stirring rod 3, thereby cleaning the clumps formed on the outer surface of the stirring rod 3 and achieving the purpose of cleaning the stirring rod 3 during use.

[0032] In this embodiment, scrapers 5 are protruding at the positions where the cleaning part 4 contacts the stirring rod 3. The lower end face of the scrapers 5 is chamfered to facilitate the scrapers 5 scraping the outer surface of the stirring rod 3.

[0033] In this embodiment, the cleaning unit 4 includes a base plate 6 that slides along the left-right direction with the inner side of the stirring rod 3, and two sets of side blocks 7 that are fixed to the upper end face of the base plate 6 by bolts. The two side blocks 7 in each set are fixed by bolts, and the two side blocks 7 in each set slide in contact with the outer surface of the stirring rod 3. The scraper 5 is fixedly set at the position where the side blocks 7 contact the stirring rod 3. The execution end of the transmission mechanism is connected to the side blocks 7. The stirring rod 3 rotates around the axis of the cylinder 1, which drives the transmission mechanism to rotate. This causes the transmission mechanism to rotate in cooperation with the stationary drive mechanism, thereby driving the side blocks 7 to slide left and right on the stirring rod 3. The side blocks 7 clean the outer surface of the stirring rod 3 through the scraper 5 to clean the clumps formed on the outer surface of the stirring rod 3, thus achieving the purpose of cleaning the stirring rod 3 during use.

[0034] In this embodiment, the transmission mechanism includes a reciprocating screw 8 that is threadedly connected to two side blocks 7 in each group. Both ends of the reciprocating screw 8 are rotatably connected to the stirring rod 3 through a fixing block 9. Both ends of the reciprocating screw 8 are coaxially fixed with gears 10, which are connected to the output end of the drive mechanism. The rotation of the ring body 2 drives the stirring rod 3 to rotate around the axis of the cylinder 1. The stirring rod 3 drives the side blocks 7 and the reciprocating screw 8 to rotate synchronously around the axis of the cylinder 1, which in turn drives the gears 10 to rotate around the axis of the cylinder 1. The gears 10 cooperate with the stationary drive mechanism to generate their own rotation, that is, the gears 10 rotate around the axis of the reciprocating screw 8, which in turn drives the reciprocating screw 8 to rotate around its own axis. The rotation of the reciprocating screw 8 drives the side blocks 7 to move left and right, which in turn causes the side blocks 7 to drive the scraper 5 to move left and right to scrape and clean the outer surface of the stirring rod 3.

[0035] In this embodiment, the driving mechanism includes a gear ring 11 fixedly disposed on the inner side wall of the cylinder 1, and the gear ring 11 meshes with each gear 10 on the corresponding side; when the reciprocating screw 8 drives the gear 10 to revolve around the axis of the cylinder 1, the gear 10 meshes with the gear ring 11 to generate a rotation around the axis of the reciprocating screw 8, thereby causing the reciprocating screw 8 to drive the side block 7 to move left and right; when the stirring rod 3 revolves, the side block 7 moves left and right at the same time, and the side block 7 cleans the stirring rod 3 while also improving the mixing effect of colored sand.

[0036] To achieve the purpose of driving the two annular bodies 2 to rotate, in this embodiment, a rotating shaft 12 is provided inside the cylinder 1 along the left-right direction. The outer surface of the rotating shaft 12 is fixedly connected to each annular body 2 through spokes 13. The rotation of the rotating shaft 12 drives the two annular bodies 2 to rotate, thereby achieving the purpose of driving the annular bodies 2 to rotate. Both ends of the rotating shaft 12 are rotatably connected to partitions 14. The partitions 14 are fixedly connected to the gear ring 11 through cover plates 15 fixedly installed on the outer side of the gear ring 11. An annular channel is formed between the partitions 14 and the gear ring 11. Each reciprocating screw 8 is located in the annular channel and moves in the annular channel when the reciprocating screw 8 revolves. The cover plates 15 are fixedly connected to the gear ring 11 and the partitions 14 by bolts, which facilitates the disassembly of the cover plates 15 and facilitates the maintenance of the gears 10.

[0037] In order to achieve the purpose of driving the rotating shaft 12 to rotate, in this embodiment, a motor 16 is fixedly installed on the right side of the cylinder 1, and the output shaft of the motor 16 is fixedly installed with the right end of the rotating shaft 12; when the motor 16 is started, the motor 16 drives the rotating shaft 12 to rotate, thereby achieving the purpose of driving the stirring rod 3 to revolve through the annular body 2.

[0038] In this embodiment, a feeding hopper 17 and a discharging hopper 18 are respectively provided on the right and left sides of the outer surface of the cylinder 1; the cylinder 1 is inclined by the support leg 19, which is lower on the left and higher on the right.

[0039] The working principle of this utility model is as follows: During use, colored sand is added into the cylinder 1 through the feeding hopper 17. Then, the motor 16 is started. The motor 16 drives the stirring rod 3 to rotate via the rotating shaft 12 and the annular body 2. The stirring rod 3 rotates around the axis of the cylinder 1, thus stirring the colored sand inside the cylinder 1. This ensures uniform heating of the colored sand and improves the sintering effect of the sintering cylinder. Simultaneously, as the stirring rod 3 rotates around the axis of the cylinder 1, it also drives the side block 7 and the bottom plate 6 to rotate synchronously. The reciprocating screw 8 is driven to rotate around the axis of the cylinder 1, which in turn drives the gear 10 to rotate around the axis of the cylinder 1. When the gear 10 revolves, it meshes with the gear ring 11, causing the gear 10 to rotate on its own axis while revolving. The rotation of the gear 10 drives the reciprocating screw 8 to rotate on its own axis. The rotation of the reciprocating screw 8 causes the side block 7 and the bottom plate 6 to move left and right, so that the side block 7 scrapes and cleans the clumps of material on the outer surface of the stirring rod 3 through the scraper 5, thus achieving the purpose of cleaning the stirring rod 3 while it is working.
