Description

Technical Field

[0001] This application relates to the field of crushers, and more specifically, to a bone crusher for crushing food additive raw materials. Background Technology

[0002] A pulverizer is a machine that crushes large solid raw materials to the required size. A pulverizer consists of coarse crushing, fine crushing, and pneumatic conveying devices. It achieves the purpose of pulverization through high-speed impact and uses wind power to pulverize the raw materials in one pass, eliminating the need for traditional screening procedures. It is mainly used in mining, building materials and other industries. Pulverizers are also needed to crush food additive raw materials, such as bones, during the processing of food additives.

[0003] Currently, when using bone crushers to crush materials, workers often need to pour the bone material into the crusher. The feeding port is high and inconvenient, and the efficiency is low due to untimely replenishment. In addition, the crushed bone material is uneven in size, which makes further processing more troublesome. Utility Model Content

Detailed Implementation

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0030] Please see Figures 1-4 This application provides a bone crusher for crushing food additive raw materials, including a grinding component 100 and a feeding and crushing component 200.

[0031] Please see Figure 1 and 2 The grinding assembly 100 includes a grinding barrel 110, a fixed grinding block 120, a rotating grinding block 130, a first motor 140, a filter screen 150, a scraper 160, and a discharge pipe 180. The fixed grinding block 120 is disposed inside the grinding barrel 110. The rotating grinding block 130 has a rotating shaft 131 at its bottom, which is rotatably disposed inside the grinding barrel 110. The first motor 140 is installed at the bottom of the grinding barrel 110 and is connected to the rotating shaft 131 for transmission. The filter screen 150 is disposed inside the grinding barrel 110. The scraper 160 is fixedly connected to the rotating shaft 131 and is attached to the filter screen 150. The discharge pipe 180 is connected to the grinding barrel 110.

[0032] The rotating grinding block 130 is close to the fixed grinding block 120, and the gap between the rotating grinding block 130 and the fixed grinding block 120 gradually decreases from top to bottom. By setting the gap between the rotating grinding block 130 and the fixed grinding block 120 to gradually decrease from top to bottom, it is beneficial for the raw material to enter between the two grinding blocks.

[0033] Specifically, a frustum 111 is provided at the bottom of the grinding barrel 110. Two scraper blades 160 are fixedly connected to the rotating shaft 131. One scraper blade 160 is in contact with the frustum 111. By setting the frustum 111 and the two scraper blades 160, one scraper blade 160 scrapes the material on the filter screen 150 to filter the material, while the other scraper blade 160 scrapes the material that falls onto the frustum 111 after filtration.

[0034] In this embodiment, there are two discharge pipes 180. One discharge pipe 180 faces the filter screen 150, and the other discharge pipe 180 faces the truncated cone 111. By setting two discharge pipes 180, it is used to discharge crushed materials of different sizes. The two discharge pipes 180 are equipped with baffles that can be easily removed and inserted to control the discharge.

[0035] Please see Figure 1 , 2 3 and 4, the feeding and crushing assembly 200 includes a crushing bin 210, crushing parts 220, a scraper conveyor 230 and a hopper 240. The crushing bin 210 is connected to the top of the grinding barrel 110, the crushing parts 220 are disposed inside the crushing bin 210, the scraper conveyor 230 is disposed at the top of the grinding barrel 110, and the hopper 240 is located at the bottom of the scraper conveyor 230.

[0036] The crushing component 220 includes a second motor 221 and a crushing roller 222. The crushing roller 222 is rotatably disposed inside the crushing chamber 210. The second motor 221 is installed on the outside of the crushing chamber 210 and is connected to the crushing roller 222. By setting the second motor 221 and the crushing roller 222, the crushing roller 222 is driven to rotate by the second motor 221 to crush the aggregate.

[0037] Specifically, there are two crushing rollers 222, and the two crushing rollers 222 are connected by gear meshing. By setting the two crushing rollers 222 to mesh, the second motor 221 can drive the two second motors 221 to rotate synchronously.

[0038] In one specific implementation, a hopper 211 is provided at the top of the crushing chamber 210. The hopper 211 is close to the top of the scraper conveyor 230. The hopper 211 is used to guide the aggregate into the crushing chamber 210.

[0039] It should be noted that a guide plate 241 is provided inside the hopper 240. The guide plate 241 is inclined towards the scraper conveyor 230. By setting the guide plate 241, the material added to the hopper 240 is guided to fall onto the scraper conveyor 230, and the scraper conveyor 230 is used to transport the aggregate.

[0040] The working principle of this bone crusher for crushing food additive raw materials is as follows: During use, the operator adds the bone material to the hopper 240, starts the scraper conveyor 230, and the scraper conveyor 230 transports the bone material to the hopper 211. The bone material then enters the crushing chamber 210 from the hopper 211. The second motor 221 is then started, driving the crushing rollers 222 to rotate. The two crushing rollers 222 rotate synchronously through gear meshing, thus crushing the bone material under the combined action of the two crushing rollers 222. The crushed bone material directly enters the grinding barrel 110. The first motor 140 is turned on, which drives the rotating shaft 131 to rotate. The rotating shaft 131 drives the rotating grinding block 130 to rotate. The rotating grinding block 130, together with the fixed grinding block 120, grinds the aggregate. The ground material falls onto the fixed filter screen 150. The rotating shaft 131 simultaneously drives the two scraper plates 160 to rotate, which speeds up the filtration of the material on the filter screen 150. Finally, the material is discharged from the two discharge pipes 180, which greatly improves the crushing and grinding efficiency, makes it convenient for workers to add materials, and reduces subsequent processing steps.

[0041] It should be noted that the specific models and specifications of the first motor 140, the second motor 221, and the scraper conveyor 230 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0042] The power supply and operating principle of the first motor 140, the second motor 221, and the scraper conveyor 230 are clear to those skilled in the art and will not be described in detail here.

[0043] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
