Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to an animal fat raw material crushing device. Background Technology

[0002] Animal fats are important raw materials in food processing, chemical production, and other fields. The efficiency and effectiveness of raw material crushing in the pre-processing stage directly affect the quality and economics of subsequent oil extraction and refining. Currently, the crushing of animal fat raw materials such as lard, beef fat, and mutton fat mainly relies on traditional crushing equipment, but the following technical problems still exist in practical applications: First, the crushing efficiency is low and the particle uniformity is poor. Traditional crushing equipment mostly adopts a single crushing structure, which has limited ability to crush large pieces of fat tissue. Animal fat raw materials often contain tough components such as fascia and connective tissue. A single crushing method is prone to incomplete crushing of raw materials, resulting in a mixture of coarse and fine particles. Secondly, the screen holes are prone to clogging, affecting continuous production. Animal fat raw materials have a certain viscosity. Especially during the crushing process, when heat is generated due to mechanical friction, the fat is prone to local melting, causing fine raw materials to adhere to the screen plate surface or clog the screen holes. Traditional equipment lacks a targeted cleaning structure, requiring frequent shutdowns for manual cleaning, interrupting the production process, reducing the continuous operation capacity of the equipment, and increasing the intensity of manual labor.

[0003] This utility model relates to an animal fat raw material crushing device, which solves the problems of low crushing efficiency, poor particle uniformity, and the phenomenon of coarse and fine particles being mixed in the current crushing equipment, as well as the easy clogging of the screen holes, which affects continuous production. Animal fat raw materials have a certain degree of viscosity, and the fat is prone to local melting, especially when heat is generated by mechanical friction during the crushing process.

[0004] This utility model provides an animal fat raw material crushing device, specifically including: a crushing barrel; The lower end face of the crushing barrel is equipped with three inclined support legs in a ring shape. A discharge pipe is fixedly installed in the middle of the lower end face of the crushing barrel. A cavity is opened inside the side wall of the crushing barrel. A screen plate is fixedly installed inside the crushing barrel. The surface of the screen plate is evenly opened with screen holes. A cooling mechanism is fixedly installed at the outer end of the crushing barrel. A drive motor is fixedly mounted on the upper end face of the top plate of the crushing barrel, and a drive shaft is connected to the lower end face of the drive motor. A fixed plate is fixedly installed on the outer end face of the lower part of the drive shaft, and three breaking teeth are installed in a ring on the outer end face of the fixed plate; The first cleaning plate is fixedly installed on the lower end surface of the drive shaft, and brushes are evenly installed on the lower end surface of the first cleaning plate. A placement plate is located on the lower end surface of a sieve plate, and a connecting rod is welded to the upper end surface of the placement plate. The connecting rod passes through the sieve plate and is fixedly connected to the first cleaning plate. The second cleaning plate is located between the sieve plate and the placement plate, and brushes are evenly installed on the upper surface of the second cleaning plate.

[0005] Furthermore, two limiting rods are welded to the lower end face of the second cleaning plate, and two through holes are symmetrically opened on the surface of the placement plate, with the limiting rods engaging in the through holes on the surface of the placement plate.

[0006] Furthermore, a connecting spring is sleeved on the outside of the limiting rod, with the upper end of the connecting spring in contact with the second cleaning plate and the lower end face of the connecting spring in contact with the placement plate.

[0007] Furthermore, a feed pipe is fixedly installed above the outer end face of the crushing barrel, the lower end of the feed pipe is divided into an inclined structure, and a ventilation pipe is fixedly installed on the outer end face of the crushing barrel.

[0008] Furthermore, the cooling mechanism includes a refrigeration unit, which is fixedly installed on the outer end face of the crushing barrel.

[0009] Furthermore, there are two fixed disks, and the length of the outer end crushing tooth of the upper fixed disk is half the length of the outer end crushing tooth of the lower fixed disk.

[0010] This utility model provides a device for crushing animal fat raw materials, which has the following beneficial effects: In this invention, the crushing teeth at the outer end of the fixed disc rotate at high speed to mechanically shear and crush the raw materials entering the crushing barrel. Since the length of the crushing teeth on the upper fixed disc is half that of the lower one, the raw materials are first coarsely crushed by the upper short teeth, which breaks down the structure of large pieces of raw materials. Then, they fall to the lower long tooth area and are deeply finely crushed by the longer crushing teeth, achieving graded crushing of coarse and fine crushing, which significantly improves crushing efficiency and particle uniformity, and ensures that the raw materials are crushed to the set particle size.

[0011] 2. The first cleaning plate rotates synchronously with the drive shaft.

The limiting rod at the lower end of the second cleaning plate is engaged in the through hole on the surface of the placement plate. A connecting spring is sleeved on the outside of the limiting rod. Under the elastic pressure of the connecting spring, it is tightly attached to the lower surface of the screen plate. The brush on the upper surface of the second cleaning plate rotates with the placement plate to clean the fine crushed raw materials remaining on the lower surface of the screen plate.

[0013] 4. Animal fat raw materials release a fishy and pungent odor when crushed. If it is released directly, it will pollute the environment. The device is connected to an external purification system through a ventilation pipe at the outside of the crushing barrel. The odorous gas generated during the crushing process enters the ventilation pipe under the action of air flow. After being adsorbed and treated by the purification system, the volatile odor components in the gas are removed, preventing the odor from being released and ensuring the air quality of the operating environment.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example 1: Please refer to Figures 1 to 6 : This utility model proposes an animal fat raw material crushing device, including: a crushing barrel 1; The lower end face of the crushing barrel 1 is equipped with three inclined support legs 103 in a ring shape. The discharge pipe 104 is fixedly installed in the middle of the lower end face of the crushing barrel 1. A cavity 105 is opened inside the side wall of the crushing barrel 1. A screen plate 106 is fixedly installed inside the crushing barrel 1. The surface of the screen plate 106 is evenly provided with screen holes. A cooling mechanism is fixedly installed at the outer end of the crushing barrel 1. Drive motor 2 is fixedly installed on the upper end face of the top plate of crushing barrel 1, and drive shaft 201 is connected to the lower end face of drive motor 2. Fixed disk 3 is fixedly installed on the outer end face of the lower part of the drive shaft 201. Three breaking teeth 301 are installed in a ring on the outer end face of the fixed disk 3. The first cleaning plate 4 is fixedly installed on the lower end surface of the drive shaft 201, and brushes are evenly installed on the lower end surface of the first cleaning plate 4. Placement plate 5 is located on the lower end surface of screen plate 106. A connecting rod 501 is welded to the upper end surface of placement plate 5. The connecting rod 501 passes through screen plate 106 and is fixedly connected to the first cleaning plate 4. The second cleaning plate 6 is located between the sieve plate 106 and the placement plate 5, and brushes are evenly installed on the upper surface of the second cleaning plate 6.

[0020] Two limiting rods 601 are welded to the lower end face of the second cleaning plate 6. Two through holes 502 are symmetrically opened on the surface of the placement plate 5. The limiting rods 601 are engaged in the through holes 502 on the surface of the placement plate 5. A connecting spring 602 is sleeved on the outside of the limiting rods 601. The upper end of the connecting spring 602 is in contact with the second cleaning plate 6, and the lower end face of the connecting spring 602 is in contact with the placement plate 5. In use, the limiting rods 601 at the lower end of the second cleaning plate 6 are engaged in the through holes 502 on the surface of the placement plate 5. The connecting spring 602 is sleeved on the outside of the limiting rods 601. Under the elastic pressure of the connecting spring 602, the screen plate 106 is tightly attached to the lower surface. The brush on the upper end face of the second cleaning plate 6 rotates with the placement plate 5 to clean the fine crushed material remaining on the lower surface of the screen plate 106. The dual cleaning structure works simultaneously from the upper and lower sides of the screen plate 106 to completely prevent the screen holes from clogging and ensure the smooth separation and discharge of the crushed material.

[0021] The cooling mechanism includes a refrigeration unit 7, which is fixedly installed on the outer end face of the crushing barrel 1. A cooling pipe 701 is fixedly installed on the outer end face of the refrigeration unit 7. The main body of the cooling pipe 701 is a spiral structure. The cooling pipe 701 is located in the cavity 105 inside the side wall of the crushing barrel 1. If the internal temperature of the crushing barrel 1 is too high, the animal fat may melt prematurely, causing the raw material to stick to the crushing teeth 301 or the screen plate 106, affecting the crushing efficiency. At this time, the refrigeration unit 7 generates cooling energy, which circulates in the cavity 105 inside the side wall of the crushing barrel 1 through the spiral cooling pipe 701. The cooling energy continuously reduces the internal ambient temperature of the crushing barrel 1 by heat exchange, keeping the temperature below the melting point of the fat, ensuring that the raw material always remains solid or semi-solid, and maintaining a stable crushing effect.

[0022] The fixed disk 3 has two parts. The length of the outer crushing tooth 301 of the upper fixed disk 3 is half the length of the outer crushing tooth 301 of the lower fixed disk 3. The crushing tooth 301 at the outer end of the fixed disk 3 rotates at high speed to mechanically shear and crush the raw material entering the crushing barrel 1. Since the length of the crushing tooth 301 of the upper fixed disk 3 is half that of the lower one, the raw material is first coarsely crushed by the upper short tooth to destroy the structure of large pieces of raw material. Then it falls to the lower long tooth area and is deeply finely crushed by the longer crushing tooth 301, realizing the graded crushing of coarse and fine crushing, significantly improving crushing efficiency and particle uniformity, and ensuring that the raw material is crushed to the set particle size.

[0023] Example 2, based on Example 1, such as Figures 1-6As shown, a feed pipe 101 is fixedly installed above the outer end face of the crushing barrel 1. The lower end of the feed pipe 101 has an inclined structure. A ventilation pipe 102 is fixedly installed on the outer end face of the crushing barrel 1. When animal fat raw materials are crushed, they will release a fishy and pungent odor. If this odor escapes from the inside of the crushing barrel 1, it will affect the surrounding gas environment. The ventilation pipe 102 is welded to the outer end face of the crushing barrel 1. The ventilation pipe 102 can be connected to the purification system. The gas inside the crushing barrel 1 enters the purification system through the ventilation pipe 102, which can purify the gas inside the crushing barrel 1 and absorb the odor in the gas, preventing the odor inside the crushing barrel 1 from escaping.

[0024] The working principle of this embodiment: In this invention, the crushing barrel 1 is stably supported on the working plane by the support leg 103. The animal fat raw materials to be crushed, such as lard and beef fat, enter the barrel through the feed pipe 101 at the upper end of the crushing barrel 1. The inclined structure at the lower end of the feed pipe 101 ensures that the raw materials slide smoothly into the crushing area. At the same time, the drive motor 2 starts, which can drive the drive shaft 201, the fixed plate 3, the first cleaning plate 4, etc. to rotate, providing power for crushing, cleaning and other processes. When the drive shaft 201 rotates, it drives the upper and lower fixed plates 3 to rotate synchronously. The crushing teeth 301 at the outer end of the fixed plate 3 rotate at high speed, mechanically shearing and crushing the raw materials entering the crushing barrel 1. Since the length of the crushing teeth 301 of the upper fixed plate 3 is half that of the lower one, the raw materials first enter through the upper short teeth. The material undergoes initial coarse crushing to break down large pieces of raw material. It then falls to the lower long-toothed area for further fine crushing by the longer crushing teeth 301, achieving graded crushing between coarse and fine crushing. This significantly improves crushing efficiency and particle uniformity, ensuring the raw material is crushed to the set particle size. The crushed material moves to the lower screen plate 106. Particles meeting the size requirements fall through the screen holes on the surface of the screen plate 106 and are finally discharged through the discharge pipe 104 at the lower end of the crushing barrel 1, entering subsequent processing stages. Unsized coarse material remains above the screen plate 106 and continues to be crushed a second time by the crushing teeth 301. During this process, the first cleaning plate 4 rotates synchronously with the drive shaft 201, and the brush at the lower end of the first cleaning plate 4 continuously cleans the upper surface of the screen plate 106 to prevent the crushed material from adhering to or clogging the surface. The screen 106 has multiple cleaning holes. Simultaneously, the first cleaning plate 4 drives the placement plate 5 to rotate synchronously via the connecting rod 501. The limiting rod 601 at the lower end of the second cleaning plate 6 engages with the through hole 502 on the surface of the placement plate 5. A connecting spring 602 is sleeved on the outside of the limiting rod 601, and the elastic pressure of the connecting spring 602 tightly presses against the lower surface of the screen plate 106. The brush on the upper surface of the second cleaning plate 6 rotates with the placement plate 5, cleaning the fine material residue remaining on the lower surface of the screen plate 106. The dual cleaning structure works synchronously from both the upper and lower sides of the screen plate 106, thoroughly preventing screen blockage and ensuring smooth separation and discharge of the crushed material. During the crushing process, mechanical friction generates heat. If the internal temperature of the crushing barrel 1 is too high, it may cause the animal fat to melt prematurely, resulting in the raw material sticking and crushing. The teeth 301 or screen plate 106 affect the crushing efficiency. At this time, the refrigeration unit 7 operates to generate cold energy, which circulates in the cavity 105 on the side wall of the crushing barrel 1 through the spiral cooling pipe 701. The internal ambient temperature of the crushing barrel 1 is continuously reduced by heat exchange, and the temperature is controlled below the melting point of the oil, ensuring that the raw material always remains solid or semi-solid, and maintaining a stable crushing effect. Animal fat raw materials will release a fishy and pungent odor when crushed. If it is directly released, it will pollute the environment. The device is connected to the external purification system through the ventilation pipe 102 at the outer end of the crushing barrel 1. The odorous gas generated during the crushing process enters the ventilation pipe 102 under the action of air flow. After being adsorbed and treated by the purification system, the volatile odor components in the gas are removed, preventing the odor from being released and ensuring the air quality of the operating environment.
