Description

Technical Field

[0001] This utility model relates to the field of material crushing technology, and in particular to a crusher. Background Technology

[0002] A pulverizer is a mechanical device that crushes large solid raw materials to the required size, and is widely used in mining, building materials, chemical, food, and pharmaceutical industries. The working principle of a pulverizer mainly relies on the impact, shearing, crushing, or grinding of materials by high-speed rotating parts. After the material enters the pulverizing chamber, it is subjected to impact, shearing, friction, and mutual collisions between the high-speed rotating moving and stationary parts, thus being pulverized into particles or powder of the required size. In the food industry, pulverizers are needed to crush various ingredients such as vegetables, fruits, meats, and grains into particle sizes suitable for processing to meet the production needs of different foods.

[0003] When using food-related grinders to grind materials, high-speed rotating cutters are usually used for processing. However, this grinding method cannot grind materials simultaneously. Some materials are ground while others are not. If all materials are to be ground, it takes a long time. When a large amount of material needs to be ground, it needs to be ground in batches. Each batch takes a long time, which will make the material processing time too long and slow down the processing rate. Utility Model Content

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] according to Figure 1-3 This utility model provides a crusher, including: a feeding device 1, a crushing device 2, a screening device 3, a crushing device 4, a blower 5, a heater 6, and a blower 7.

[0021] The feeding device 1 is located on one side of the crushing device 2; the crushing device 2 is connected to the screening device 3; the screening device 3 includes: a vibrating screen 31 and a return pipe 32; the return pipe 32 is located on one side of the vibrating screen 31; the return pipe 32 is connected to the crushing device 2.

[0022] When materials need to be crushed, they are first fed into the feeding device 1 and then sent to the crushing device 2. The materials are crushed in the crushing device 2. After the materials have been crushed in the crushing device 2 for a certain period of time, the crushing device 2 is turned on and the materials are sent to the screening device 3. At this time, most of the materials are of qualified specifications, while some are not crushed or not crushed to the required specifications and are in the screening device 3. Through the vibrating screen 31 of the screening device 3, the qualified materials can be screened down, while the unqualified materials are retained on the vibrating screen 31, thus separating the two sizes of materials. At the same time, a return pipe 32 is also provided on the screening device 3. The return pipe 32 is located on one side of the vibrating screen 31 and is connected to the crushing device 2, so that the larger materials can be transported through the vibrating screen 31 to the return pipe 32 and then back to the crushing device 2 to be crushed together with the subsequently added materials. When a large amount of material needs to be crushed in batches, a batch of material can be fed in first for crushing. After crushing for a certain period of time, the material is sent to the screening device 3. The qualified material continues to be conveyed, while the unqualified material is returned to the crushing device 2, and then the next batch of material is fed in for crushing together. This process is repeated, which shortens the total crushing time of the material. In other words, each time the material is crushed, it contains a large amount of uncrushed material, resulting in higher crushing efficiency. This avoids the situation where the crushing device is still processing when there is a small amount of uncrushed material, which would lead to a small amount of crushed material, lower crushing efficiency, and lower processing rate.

[0023] The vibrating screen 31 is inclined from the side away from the return pipe 32 to the other side. The screening device 3 also includes: an inclined plate 33 and a discharge port 34; the inclined plate 33 is located on the side of the vibrating screen 31 closer to the ground; the discharge port 34 is located on one side of the inclined plate 33; the inclined plate 33 is inclined toward the discharge port 34.

[0024] The vibrating screen 31 is inclined from the side away from the return pipe 32 to the other side, so that the material can gradually move towards the return pipe 32 with the vibrating screen 31, which is conducive to the return of the material. At the same time, the screened material will fall on the inclined plate 33 and slide down from the inclined plate 33 to the discharge port 34.

[0025] One end of the crushing device 4 is connected to the feeding device 1, and the other end is connected to the crushing device 2. The feeding device 1 includes: a feeding hopper 11 and a feeding pipe 12; the feeding hopper 11 is connected to the feeding pipe 12; the feeding pipe 12 is connected to the crushing device 4; an expansion pipe 121 is provided on the side of the feeding pipe 12 near the crushing device 4. It also includes: a blower 5; the blower 5 includes: an air pipe 51; the air pipe 51 is located on the side of the feeding pipe 12 away from the crushing device 4; the air pipe 51 is connected to the feeding pipe 12. It also includes: a heater 6 and a blower 7; the blower 7 is located on both sides of the vibrating screen 31; the heater 6 is connected to the blower 7.

[0026] Some food raw materials, such as nuts, are quite hard, and the high-speed rotating cutter typically used in the crushing device 2 is insufficient to crush them. This invention incorporates a crushing device 4 between the feeding device 1 and the crushing device 2. This allows materials to be first fed into the crushing device 4, where they are crushed before being transferred to the crushing device 2, facilitating subsequent crushing. During feeding, materials are placed into the feeding hopper 11 and fed into the feeding pipe 12, and then conveyed to the crushing device 4. A blower 5 is also included, connected to the feeding pipe 12 via an air pipe 51. When feeding is required, the blower is activated, causing the air pipe 51 to blow air into the crushing device 4 through the feeding pipe 12. This facilitates the conveying of materials into the crushing device 4 when they are fed into the feeding hopper 11. An expansion pipe 121 is provided on the side of the feed pipe 12 near the crushing device 4. The diameter of the expansion pipe 121 on the side near the crushing device 4 is larger than that of the feed pipe 12, so that the air blown out by the blower pipe 51 will spread to the surrounding area when it passes through this point. This avoids the material being transported because the pipe diameter is too small, causing it to accumulate in a small area, resulting in excessive local pressure and uneven crushing during crushing. In addition, the crushing tools used in the crushing device 4 are mostly jaw plates. The material is crushed by the mutual squeezing of two jaw plates. Although this crushing method is effective, the squeezing force between the jaw plate and the material can easily cause the material to stick to the jaw plate and not fall off naturally. This can easily lead to some material not being conveyed to the crushing device 2, resulting in material waste. This utility model is equipped with a blower 5. After the material is crushed, the connection between the crushing device 4 and the feeding device 1 and the crushing device 2 can be opened. At the same time, the blower 5 is turned on, so that the air pipe 51 blows air into the feeding pipe 12, so that the material is conveyed to the crushing device 2. At the same time, the blown air can also cause the material adhering to the jaw plate to fall off and be conveyed to the crushing device 2. The feeding pipe 12 is provided with an expansion pipe 121 on the side near the crushing device 4, so that the blown air can spread to the surrounding area, so that all parts of the jaw plate can be blown off, avoiding the situation where the air outlet is too small and the material in some parts of the jaw plate cannot be blown off by the wind. This utility model also provides heaters 6 and blowers 7 on both sides of the vibrating screen 31. When the material passes through the crushing device 2 and falls onto the vibrating screen 31, the heaters and blowers 7 are activated to blow hot air onto the material, so that the material can be dried by the hot air and avoid some raw materials with high humidity from adhering to the vibrating screen 31 and causing blockage.

[0027] Working principle and usage process of this utility model:

[0028] When material needs to be crushed, blower 5 is turned on, causing air to blow through air pipe 51 into feed pipe 12. Material is then fed into feed hopper 11, falling from feed hopper 11 into feed pipe 12. The material is then blown into crushing device 4 by air from air pipe 51. If the material needs to be crushed, the jaw plates of crushing device 4 are activated to crush the material. The connection between crushing device 4 and feed device 1 and crushing device 2 is then opened, and blower 5 is turned on, causing air to blow through air pipe 51 into feed pipe 12. This allows the material to be conveyed into crushing device 2, and the blown air is diffused by expansion pipe 121, causing material adhering to the jaw plates to fall off and be conveyed to… The material is placed inside the crushing device 2 and then crushed for a certain period of time. The material is then conveyed to the screening device 3, where it falls onto the vibrating screen 31. At the same time, the blower 7 and heater 6 on both sides of the vibrating screen 31 are activated to blow hot air onto the material. The material is vibrated and screened on the vibrating screen 31. Material that meets the requirements is screened out and falls onto the inclined plate 33, then slides down from the inclined plate 33 to the discharge port 34 for discharge. Larger materials are retained on the vibrating screen 31 and slide down from the vibrating screen 31 to the return pipe 32, where they flow back into the crushing device 2 and are crushed together with the next batch of material to be crushed.

[0029] In summary, this utility model provides a screening device after the crushing device, which allows the material to be conveyed to the screening device for screening after a certain crushing time. The material that does not meet the requirements will be returned to the crushing device and crushed together with the next batch of material. This ensures that the crushing device can always crush a large amount of material when it is working, so as to prevent the crushing device from spending too much time crushing a small amount of uncrushed material in a batch, which would result in a low processing rate.
