Description

Technical Field

[0001] This utility model relates to the field of feeding hopper technology, specifically an anti-clogging powder feeding hopper. Background Technology

[0002] In many industrial production sectors today, the handling and feeding of powdered materials is a crucial step. For example, in the building materials manufacturing industry, powdered raw materials such as cement and lime powder need to be precisely and continuously fed into production equipment; in the food processing industry, the feeding of flour, sugar powder, etc., directly affects product quality and the smoothness of the production process; in the chemical industry, various fine chemical powders are key starting materials for the production of complex chemicals. Feeding hoppers are required in the process of feeding powdered materials.

[0003] Because powder materials are inherently hygroscopic, they readily absorb moisture from the air during storage or transportation, leading to clumping. This is especially true in high-humidity environments, such as the rainy season in southern China. Even in warehouses with some protective measures, powder materials frequently become damp and clump together. Once these clumps enter the feeding hopper, they can easily get stuck at the discharge port or inside the hopper, hindering the normal flow of powder materials. Therefore, an anti-clogging powder feeding hopper is needed to solve the above-mentioned technical problems. Utility Model Content

[0036] The present invention will now be further described with reference to the accompanying drawings.

[0037] like Figures 1 to 7 As shown, an anti-clogging powder feeding hopper includes a feeding hopper 10. An inclined feed inlet 11 is connected to one side of the feeding hopper 10. A vibrating motor 12 is installed on the side of the feeding hopper 10 adjacent to the feed inlet 11. An inclined filter screen 20 is fixedly installed inside the feeding hopper 10. The filter screen 20 is used to filter agglomerated materials. The top of the filter screen 20 corresponds to the bottom of the feed inlet 11. An arc-shaped collecting filter screen 30 is connected to the bottom of the filter screen 20. The collecting filter screen 30 is used to collect the agglomerated materials filtered by the filter screen 20. A crushing component 40 is provided on one side of the feeding hopper 10, and the crushing component 40 corresponds to the collecting filter screen 30. The crushing component 40 is used to... The crushing component 40 is connected to a receiving buffer component for the agglomerated material collected by the crushing and collecting filter screen 30. The receiving buffer component is used to receive a portion of the material. A heating box 50 is provided on the side of the feeding hopper 10 away from the feed inlet 11. Multiple heating wires 51 are provided inside the heating box 50. A heat conduction component and a drying component are connected to the heating box 50. The heat conduction component is used to conduct the heat inside the heating box 50 to the collecting filter screen 30, thereby raising the temperature of the collecting filter screen 30. The drying component is used to dry the material. A cleaning component 60 is provided on one side of the feeding hopper 10. The cleaning component 60 is used to clean the filter screen 20 and prevent the filter screen 20 from becoming clogged.

[0038] During the feeding process, the filter screen 20 can filter materials that have clumped due to moisture or other factors. The vibration force generated by the vibrating motor 12 causes the clumped materials to move downward and enter the interior of the collection filter screen 30. After being crushed by the crushing component 40, the clumped materials pass through the mesh of the collection filter screen 30 under the vibration force of the vibrating motor 12 and fall out of the discharge port of the feeding hopper 10.

[0039] like Figure 3 and Figure 5 The crushing assembly 40 includes a motor 41 connected to the feeding hopper 10. The output end of the motor 41 is connected to a rotating shaft 42. Multiple crushing blades 43 are fixedly connected to the outer surface of the rotating shaft 42. The rotating shaft 42 passes through the feeding hopper 10 and is rotatably connected to the feeding hopper 10. A pulley 44 is fixedly connected to the end of the rotating shaft 42 away from the motor 41.

[0040] After the filter screen 20 filters the agglomerated material, the agglomerated material enters the interior of the collection filter screen 30 under the action of the vibrating motor 12. During this process, the motor 41 is started and the rotating shaft 42 will drive multiple crushing blades 43 to rotate. The multiple rotating crushing blades 43 crush the agglomerated material collected inside the collection filter screen 30.

[0041] It should be noted that the center of the rotating shaft 42 is the same as the center of the collecting screen 30, so that the rotating shaft 42 can drive the crusher 43 to rotate smoothly, and the crusher 43 can better crush the material inside the collecting screen 30.

[0042] like Figure 3 and Figure 5 The material receiving buffer assembly includes a second rotating shaft 45 that is rotatably connected to the feeding hopper 10. One end of the second rotating shaft 45 is fixedly connected to a second pulley 46. The second pulley 46 and the first pulley 44 are connected by belt drive. Multiple receiving plates 47 are fixedly connected to the outer surface of the second rotating shaft 45. A receiving space is formed between the multiple receiving plates 47 and the second rotating shaft 45.

[0043] After the material is filtered by the filter screen 20, a portion of the filtered material will fall into the receiving space. The receiving space can hold a portion of the material, preventing a large amount of material from falling from the discharge port of the feeding hopper 10 at the same time, thus preventing the material from clogging the discharge port of the feeding hopper 10. While the rotating shaft 42 drives the crusher 43 to rotate and crush the material, the rotating shaft 45 will rotate under the transmission action of the pulley 44, belt and pulley 46, thereby tilting the material inside the receiving space downward and causing the material to fall from the discharge port of the feeding hopper 10.

[0044] It should be noted that the receiving plate 47 is located below the filter screen 20, the minimum distance between the rotating shaft 45 and the filter screen 20 is greater than the length of the receiving plate 47, and the minimum distance between the rotating shaft 45 and the discharge port of the feeding hopper 10 is greater than the length of the receiving plate 47. This ensures that the receiving plate 47 will not interfere with the filter screen 20 and the feeding hopper 10 during rotation, and ensures that the receiving plate 47 can rotate smoothly and perform the receiving operation.

[0045] like Figure 1 , Figure 3 and Figure 7 The heat-conducting component includes multiple heat-conducting rods 52 connected to the heating box 50. The ends of the multiple heat-conducting rods 52 are connected to a heat-conducting plate 53. The heat-conducting plate 53 is located inside the feeding hopper 10 and connected to the end of the collecting filter screen 30. Through the heat-conducting rods 52 and the heat-conducting plate 53, the heat generated by the heating wire 51 can be conducted to the collecting filter screen 30, thereby increasing the temperature of the collecting filter screen 30. This allows the material to be crushed inside the collecting filter screen 30 while also being dried. The drying component includes a fan 54 connected to the feeding hopper 10. The fan 54 is connected to the inside of the heating box 50 through a pipe. The fan 54 is connected to a diversion pipe 55 through a pipe. The length direction of the diversion pipe 55 is parallel to the length direction of the filter screen 20. Multiple drying nozzles 56 are evenly connected to the diversion pipe 55.

[0046] During the feeding process, the blower 54 can be started to transport the heat generated by the heating wire 51 through the pipeline to the inside of the diversion pipe 55 and spray it out through multiple drying nozzles 56. The hot air flow sprayed out by the drying nozzles 56 can dry the material on the filter screen 20 and raise the temperature inside the feeding hopper 10, thereby better drying the material.

[0047] It should be noted that the heat-conducting rod 52, heat-conducting plate 53 and material collection filter screen 30 are all made of metal materials with good thermal conductivity, which can quickly conduct heat while ensuring structural strength.

[0048] like Figure 1 , Figure 3 and Figure 6The cleaning assembly 60 includes a guide rail 61 connected to the feeding hopper 10. The length direction of the guide rail 61 is parallel to the length direction of the filter screen 20. A T-shaped mounting base 62 is slidably connected to the guide rail 61. A second motor 63 is fixedly installed on one side of the mounting base 62. A cleaning brush roller 64 is fixedly installed at the output end of the second motor 63. The cleaning brush roller 64 is provided with bristles, and the bristles of the cleaning brush roller 64 are in contact with the filter screen 20. The feeding hopper 10 is provided with a drive structure that drives the mounting base 62 to move. The drive structure includes a third motor 65 installed on the feeding hopper 10. A lead screw 66 is fixedly connected to the output end of the third motor 65. The length direction of the lead screw 66 is parallel to the length direction of the guide rail 61. A connecting bracket 67 connected to the mounting base 62 is threaded onto the outer surface of the lead screw 66.

[0049] When it is necessary to clean the filter screen 20, start motor 3 65 to rotate the lead screw 66. At this time, the connecting frame 67 will drive the mounting base 62 to move along the length of the guide rail 61. The cleaning brush roller 64 will move at this time. During this process, start motor 2 63 and the cleaning brush roller 64 will rotate. The cleaning operation of the filter screen 20 is performed by the movement and rotation of the cleaning brush roller 64, which greatly avoids the situation of material clogging the filter screen 20.

[0050] like Figure 1 , Figure 4 and Figure 6 A guide sealing assembly is provided between the feeding hopper 10 and the mounting base 62. The guide sealing assembly includes a connecting groove 13 opened on one side of the feeding hopper 10 and a folding sealing curtain 68 connected to the mounting base 62. The length direction of the connecting groove 13 is parallel to the length direction of the filter screen 20. There are two folding sealing curtains 68, and both folding sealing curtains 68 are connected to the inner wall of the connecting groove 13.

[0051] Part of the mounting base 62 is located inside the connecting groove 13 and is slidably connected to the connecting groove 13. During the movement of the mounting base 62, one folding sealing curtain 68 is stretched and the other folding sealing curtain 68 is compressed. The folding sealing curtain 68 performs a blocking and sealing operation on the connecting groove 13 to prevent material from falling outside the feeding hopper 10 through the connecting groove 13.

[0052] It should be noted that the folding sealing curtain 68 is made of plastic, which makes it relatively easy for the folding sealing curtain 68 to deform. In addition, the folding sealing curtain 68 is adapted to the size of the connecting groove 13, which can fully cover and seal the connecting groove 13.
