Description

Technical Field

[0001] This utility model relates to the field of pulverizer technology, and in particular to an anti-clogging mechanism for an ultrafine pulverizer. Background Technology

[0002] The pulverizer is suitable for small-scale Chinese medicine factories, pharmacies, and hospitals, as well as chemical plants, mines, and research institutions. However, existing pulverizers tend to accumulate powder and become clogged on their inner walls after a period of use.

[0003] The utility model patent with publication number CN214021208U provides an ultra-fine pulverizer that prevents powder caking and clogging. The rotation of the pulverizing blades breaks the raw material into smaller pieces, and then the crushing blades further grind the smaller raw material into powder. The raw material adhering to the inner wall of the pulverizing chamber is also scraped off by the rotating scraper. After being filtered by the scraper, it moves downward through the feed pipe, thereby preventing powder caking and clogging on the inner wall of the pulverizer.

[0004] The above solution uses a scraper to remove the raw material adhering to the inner wall of the crushing chamber to prevent powder from accumulating and clogging the inner wall of the crusher. However, the raw material is prone to clump together when it is in the discharge chamber, which affects the product quality. Utility Model Content

[0005] The purpose of this invention is to provide an anti-caking and clogging mechanism for an ultrafine pulverizer, which solves the problem that raw materials easily clump together in the discharge bin, affecting product quality.

[0006] To achieve the above objectives, this utility model provides an anti-caking and clogging mechanism for an ultrafine pulverizer, comprising an ultrafine pulverizer body with a discharge hopper and an anti-caking component; the anti-caking component includes a filter plate, a first spring, a connecting piece, a triangular plate, and a rotating shaft; the discharge hopper has an installation cavity on its side; the filter plate is slidably connected to the ultrafine pulverizer body and is located inside the discharge hopper; the connecting piece is fixedly connected to the filter plate and is located inside the installation cavity; the two ends of the first spring are fixedly connected to the ultrafine pulverizer body and the connecting piece, respectively, and the first spring is located above the connecting piece; the rotating shaft is rotatably connected to the ultrafine pulverizer body; the triangular plate is fixedly connected to the rotating shaft and is sleeved on the outside of the rotating shaft, and is located below the filter plate.

[0007] The anti-caking component further includes an extrusion structure, which includes a rotating rod, a U-shaped mounting frame, and a roller. One end of the rotating rod is rotatably connected to the body of the ultrafine pulverizer, and the other end of the rotating rod is fixedly connected to the U-shaped mounting frame. The roller is rotatably connected to the U-shaped mounting frame and is located inside the U-shaped mounting frame. The roller is fitted and disposed above the filter plate.

[0008] The extrusion structure further includes a limiting block, which is fixedly connected to the body of the ultrafine pulverizer and is located below the rotating rod.

[0009] The extrusion structure further includes a second spring, the two ends of which are fixedly connected to the body of the ultrafine pulverizer and the rotating rod, respectively, and the second spring is located below the rotating rod.

[0010] The anti-powdering component further includes a shielding block, a receiving cavity is provided above the mounting cavity, the bottom of the shielding block is fixedly connected to the connecting piece, and the top of the shielding block is located inside the receiving cavity.

[0011] This utility model discloses an anti-clogging mechanism for an ultrafine pulverizer. When the rotating shaft drives the triangular plate to rotate, causing the apex of the triangular plate to contact the filter plate, the apex of the triangular plate lifts the filter plate upward. At this time, the first spring is compressed and generates a restoring force. When the triangular plate rotates, the apex of the triangular plate does not contact the bottom of the filter plate. The filter plate falls rapidly under the action of the first spring and its own gravity until it re-contacts the triangular plate, thereby achieving the shaking of the filter plate to dislodge the powder material on the filter plate and disperse the clumps of powder material on the filter plate. This solves the problem that the raw material easily clumps together in the discharge bin, affecting product quality. Attached Figure Description

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the anti-caking and clogging mechanism of an ultrafine pulverizer according to this utility model. Figure 2 This is a structural cross-sectional view of an anti-caking and clogging mechanism for an ultrafine pulverizer according to this utility model. Figure 3 This utility model relates to an anti-caking and clogging mechanism for an ultrafine pulverizer. Figure 2 A magnified view of a portion of point A in the middle.

[0019] This utility model provides an anti-caking and clogging mechanism for an ultrafine pulverizer, including an ultrafine pulverizer body 100 with a discharge hopper 110 and an anti-caking component; the anti-caking component includes a filter plate 210, a first spring 220, a connecting piece 230, a triangular plate 240, a rotating shaft 250, a pressing structure, and a blocking block 270; the pressing structure includes a rotating rod 261, a U-shaped mounting bracket 262, a roller 263, a limiting block 264, and a second spring 265;

[0020] In this specific embodiment, the side of the discharge hopper 110 is provided with an installation cavity 120. The filter plate 210 is slidably connected to the ultrafine pulverizer body 100 and is located inside the discharge hopper 110. The connecting piece 230 is fixedly connected to the filter plate 210 and is located inside the installation cavity 120. The two ends of the first spring 220 are fixedly connected to the ultrafine pulverizer body 100 and the connecting piece 230, respectively, and the first spring 220 is located above the connecting piece 230. The rotating shaft 250 is rotatably connected to the ultrafine pulverizer body 100. The triangular plate 240 is fixedly connected to the rotating shaft 250 and is sleeved on the outside of the rotating shaft 250. The triangular plate 240 is located below the filter plate 210. The ultrafine pulverizer body 100 has a pulverizing chamber above the discharge chamber 110 to crush raw materials into powder. The powdered material falls onto the filter plate 210, which is used to filter the powdered material. The rotating shaft 250 can rotate under the action of a motor, and the triangular plate 240 rotates together with the rotating shaft 250. The connecting piece 230 is used to connect the filter plate 210. The first spring 220 holds the connecting piece 230 downward so that the bottom of the filter plate 210 contacts the triangular plate 240. When the rotating shaft 250 drives the triangular plate 240 to rotate, the apex of the triangular plate 240 contacts the filter plate. When the plates 210 come into contact, the apex of the triangular plate 240 pushes the filter plate 210 upward. At this time, the first spring 220 is compressed and generates a restoring force. When the triangular plate 240 rotates, the apex of the triangular plate 240 does not contact the bottom of the filter plate 210. The filter plate 210 falls rapidly under the action of the first spring 220 and its own gravity until it comes into contact with the triangular plate 240 again, thereby realizing the shaking of the filter plate 210 to shake off the powder raw materials on the filter plate 210 and to disperse the clumps of powder raw materials on the filter plate 210. This solves the problem that the raw materials are easy to clump together in the discharge bin 110, which affects the product quality.

[0021] Furthermore, one end of the rotating rod 261 is rotatably connected to the ultrafine pulverizer body 100, and the other end of the rotating rod 261 is fixedly connected to the U-shaped mounting frame 262. The roller 263 is rotatably connected to the U-shaped mounting frame 262, and the roller 263 is located inside the U-shaped mounting frame 262, fitting snugly above the filter plate 210. The extrusion structure is used to extrude the powdered raw material on the filter plate 210, thereby extruding and breaking up the agglomerated raw material. The rotating rod 261 is rotatable relative to the ultrafine pulverizer body 100. The U-shaped mounting bracket 262 is used to mount the roller 263. The roller 263 is rotatable relative to the U-shaped mounting bracket 262. When the triangular plate 240 drives the rotating shaft 250 to move upward, the filter plate 210 squeezes the roller 263 upward, causing the rotating rod 261 to rotate and the roller 263 to roll on the filter plate 210, thereby dispersing the agglomerated powder material on the filter plate 210 so that the powder material can fall off the filter plate 210.

[0022] Specifically, the limiting block 264 is fixedly connected to the body 100 of the ultrafine pulverizer, and the limiting block 264 is located below the rotating rod 261. The limiting block 264 is used to limit the rotation angle of the rotating rod 261, so that when the rotating rod 261 rotates to its lowest position, it forms a certain angle with the filter plate 210, so that the filter plate 210 can squeeze the roller 263 and cause the roller 263 to roll on the filter plate 210.

[0023] The second spring 265 is fixedly connected at both ends to the ultrafine pulverizer body 100 and the rotating rod 261, respectively, and is located below the rotating rod 261. When the rotating rod 261 rotates upward, the second spring 265 is stretched and generates a restoring force. Therefore, when the filter plate 210 moves downward, the roller 263 can be reset under the action of the second spring 265, so that the roller 263 can roll on the filter plate 210 again.

[0024] Additionally, a receiving cavity 130 is provided above the mounting cavity 120. The bottom of the blocking block 270 is fixedly connected to the connecting piece 230, and the top of the blocking block 270 is located inside the receiving cavity 130. The blocking block 270 can slide inside the receiving cavity 130, and the blocking block 270 is used to block the mounting cavity 120 to prevent raw materials from falling into the mounting cavity 120.

[0025] When using an anti-clogging mechanism for an ultrafine pulverizer, the raw material is pulverized into powder in the ultrafine pulverizer body 100 and falls onto the filter plate 210. When the rotating shaft 250 drives the triangular plate 240 to rotate, causing the apex of the triangular plate 240 to contact the filter plate 210, the apex of the triangular plate 240 pushes the filter plate 210 upward. At this time, the first spring 220 is compressed and generates a restoring force. When the triangular plate 240 rotates, the apex of the triangular plate 240 does not contact the bottom of the filter plate 210. The filter plate 210 falls rapidly under the action of the first spring 220 and its own gravity until it contacts the bottom of the filter plate 210. The plates 240 re-engage, causing the filter plate 210 to vibrate and dislodge the powder material on it, thus breaking up any clumps. Simultaneously, when the triangular plate 240 drives the rotating shaft 250 upwards, the filter plate 210 presses upwards against the roller 263, causing the rotating rod 261 to rotate and the roller 263 to roll on the filter plate 210, further breaking up any clumps of powder material and allowing it to fall off. This solves the problem of raw materials easily clumping together in the discharge hopper 110, affecting product quality.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
