Description

Technical Field

[0001] The utility model relates to the technical field of ultrafine pulverizers, in particular to a silo clearing device for an ultrafine pulverizer. Background Art

[0002] A pulverizer is a machine that crushes large solid raw materials to the required size. The pulverizer's operating principle is to feed the material to be processed into the equipment through the feed port. Inside the pulverizer, the material is subjected to the impact, shearing, and friction of high-speed rotating blades or hammers, breaking the material into smaller chunks or particles. An ultrafine pulverizer is a type of pulverizer that uses air separation, heavy-pressure grinding, and shearing to achieve ultrafine grinding of dry materials. The pulverized material falls into a silo at the bottom, where it is then sucked away by a fan. Because the powder is extremely fine and is affected by static electricity, some material will accumulate at the bottom of the silo, preventing the fan from sucking it away. This not only results in material waste, but can also cause the silo's discharge port to become clogged over time, affecting its normal operation and forcing the machine to be shut down for maintenance.

[0003] In response to the above problems, the prior art patent publication number CN218282073U discloses a hopper clearing device for an ultrafine pulverizer. The device drives the discharge lever to rotate through a driving motor, scrapes the powdered material accumulated inside the hopper to the discharge port, and transports the material out through a fan. This can prevent the material from accumulating in the hopper, reducing material waste and preventing the discharge port from being blocked due to material accumulation, thereby improving production efficiency.

[0004] However, in the above method, the length specification of the unloading lever is fixed, which makes it inconvenient to adjust the length according to the size of the silo, and has poor applicability. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0020] The first embodiment of this application is:

[0021] See also Figures 1 to 3 ,in Figure 1 This is a schematic structural diagram of the first embodiment of the present invention. Figure 2 This is a partial structural diagram of the first embodiment of the present utility model. Figure 3 This utility model Figure 2 AA line structural cross-sectional view.

[0022] The present invention provides a hopper 101 clearing device for an ultrafine pulverizer, comprising a hopper 101 and a clearing mechanism, wherein the clearing mechanism comprises a motor 102, a box body 103, a motor 104, an elliptical plate 105, two force-bearing plates 106, a spring 107, two sets of scraping assemblies and two telescopic rods 108, wherein the scraping assemblies comprise a bottom scraping block 109, a first rubber pad 110, an inclined scraping block 111 and a second rubber pad 112. The above-mentioned solution solves the technical problem in the prior art that the length specification of the unloading lever is fixed, which makes it inconvenient to adjust the length according to the size of the hopper 101 and has poor applicability.

[0023] According to this specific embodiment, the silo 101 is provided with a discharge port 113 . When in use, the discharge port 113 is used to discharge the material in the silo 101 .

[0024] The motor 102 is mounted on the silo 101 and is located below the silo 101. The output end of the motor 102 is fixedly connected to the box body 103. The box body 103 has a groove 114 and two guide grooves 115. The two force plates 106 are slidably connected to the groove 114. There are two springs 107. One end of each of the two springs 107 is fixedly connected to one of the force plates 106, and the other end of each of the two springs 107 is fixedly connected to the other force plate 106. The elliptical plate 105 is mounted on the box body 103, and the two elliptical plates 105 are in contact with the two force-bearing plates 106. The two groups of scraper assemblies are respectively slidably connected to the corresponding guide grooves 115, and the two groups of scraper assemblies are respectively fixedly connected to the corresponding force-bearing plates 106. At the same time, the two groups of scraper assemblies are in contact with the silo 101. The box body 103 has a rounded structure 116. By setting the clearing mechanism, the motor 102 is started, and the output end of the motor 102 drives the box body 103 to rotate, and the box body 103 drives The two groups of scraper assemblies rotate, so that the two groups of scraper assemblies scrape the materials on the bottom and inner wall of the silo 101 and discharge them to the discharge port 113. When in use, when it is necessary to adjust the two groups of scraper assemblies to adapt to the silo 101 according to the size of the silo 101, it is only necessary to start the motor 104. The motor 104 drives the elliptical plate 105 to rotate. When the elliptical plate 105 rotates, it abuts against the two force-bearing plates 106, so that the two force-bearing plates 106 slide in the groove 114. The two force-bearing plates 106 are 6 both slide in the groove 114 and drive the two groups of the scraper assemblies to slide in the corresponding guide grooves 115, so that the two groups of the scraper assemblies move relative to each other. Conversely, when the motor 104 drives the elliptical plates 105 to rotate in the opposite direction, it no longer resists the two elliptical plates 105. The two elliptical plates 105 are pulled closer to each other by the contraction force of the spring 107, so that the two groups of the scraper assemblies are closer to each other. In this way, the two groups of the scraper assemblies can be adjusted to adapt to silos 101 of different sizes, thereby improving applicability.

[0025] Secondly, the two ends of each telescopic rod 108 are fixedly connected to the corresponding force-bearing plate 106, so that the telescopic rod 108 is located between the two force-bearing plates 106. When in use, by setting two telescopic rods 108, when the two force-bearing plates 106 move, the two force-bearing plates 106 drive the telescopic rod 108 to extend or contract accordingly, thereby improving the stability of the force-bearing plate 106.

[0026] At the same time, the bottom scraper 109 is fixedly connected to the corresponding force-bearing plate 106, the first rubber pad 110 is arranged on the bottom scraper 109, the inclined scraper 111 is fixedly connected to the bottom scraper 109, and the second rubber pad 112 is arranged on the inclined scraper 111. The first rubber pad 110 and the second rubber pad 112 are both in contact with the silo 101. During specific use, when the box body 103 rotates, it drives the bottom scraper 109 to rotate, and the bottom scraper 109 drives the inclined scraper 111 to move, so that the bottom scraper 109 and the inclined scraper 111 drive the first rubber pad 110 and the second rubber pad 112 to rotate, thereby scraping the material on the bottom and inner wall of the silo 101.

[0027] The hopper 101 clearing device of the ultrafine pulverizer of this embodiment is used. By setting the clearing mechanism, the motor 102 is started, and the output end of the motor 102 drives the box body 103 to rotate, and the box body 103 drives the two groups of the scraping assemblies to rotate, so that the two groups of the scraping assemblies scrape the materials on the bottom and inner wall of the hopper 101 to the discharge port 113 for discharge. In specific use, when it is necessary to adjust the two groups of the scraping assemblies to adapt to the hopper 101 according to the size of the hopper 101, it is only necessary to start the motor 104, and the motor 104 drives the elliptical plate 105 to rotate. When the elliptical plate 105 rotates, it abuts against the two force-bearing blocks. The plate 106 causes the two force-bearing plates 106 to slide in the groove 114. When the two force-bearing plates 106 slide in the groove 114, they drive the two groups of scraper assemblies to slide in the corresponding guide grooves 115 respectively, so that the two groups of scraper assemblies move relative to each other. On the contrary, when the motor 104 drives the elliptical plate 105 to rotate in the opposite direction, it no longer resists the two elliptical plates 105. The two elliptical plates 105 are pulled closer to each other by the contraction force of the spring 107, so that the two groups of scraper assemblies are closer to each other. In this way, the two groups of scraper assemblies can be adjusted to adapt to silos 101 of different sizes, thereby improving applicability.

[0028] When the box body 103 rotates, the bottom scraper 109 is driven to rotate, and the bottom scraper 109 drives the inclined scraper 111 to move, so that the bottom scraper 109 and the inclined scraper 111 drive the first rubber pad 110 and the second rubber pad 112 to rotate, scraping the material on the bottom and inner wall of the silo 101.
