A multi-functional coaxial crusher with built-in forward and reverse steering

Abstract

This utility model discloses a multi-functional coaxial pulverizer with built-in forward and reverse steering, including a frame. The combination of a sieve plate and an air separator effectively achieves precise separation of coarse grains and bran. The sieve plate uses the difference in aperture size to screen the pulverized material, allowing granular coarse grains to fall through while blocking bran above it. The airflow generated by the air separator further blows the bran off the sieve plate. This dual separation mechanism improves the separation efficiency and purity of granular coarse grains and bran. The connection between the negative pressure adsorption component and the storage hopper provides strong and stable power for bran discharge. The negative pressure adsorption component quickly sucks away and collects the bran separated in the storage hopper through a connecting pipe, preventing secondary blockage caused by bran accumulation. This reduces the pollution of the production environment caused by bran dispersion, improves the cleanliness of the production site, and further ensures the stability and production efficiency of the equipment.

Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, specifically to a multi-functional coaxial crusher with built-in forward and reverse steering. Background Technology

[0002] With the popularization of healthy eating concepts, the market demand for whole grains (such as corn, sorghum, oats, buckwheat, etc.) continues to grow due to their rich dietary fiber and nutrients. One of the core steps in whole grain processing is crushing, which requires breaking the grains into suitable particle sizes for use in the production of flour, feed, or food ingredients.

[0003] Currently, the mainstream crushing equipment in the field of coarse grain processing mainly includes hammer mills. Although some mills are equipped with a chaff discharge port, the chaff produced during the crushing process is light and easily adsorbed. In addition, the airflow design of traditional equipment is unreasonable, which often leads to blockage of the chaff discharge channel. Frequent shutdowns for cleaning are required, which seriously affects production efficiency. Therefore, we need to propose a multi-functional coaxial mill with built-in forward and reverse steering. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-functional coaxial crusher with built-in forward and reverse steering. By setting up a combination of a sieve plate and an air separation component and a negative pressure adsorption component, it achieves precise separation of granular coarse grains and bran, and efficient discharge of bran, thereby solving the clogging problem and addressing the issues raised in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-functional coaxial pulverizer with built-in forward and reverse steering includes: a frame, on the top of which a coaxial pulverizer body is fixedly installed, and a forward and reverse switch is installed on the top of the coaxial pulverizer body;

[0007] The bottom of the feed hopper is fixedly connected to the hopper of the coaxial crusher body;

[0008] The storage hopper is fixedly connected to the bottom of the silo. A screen plate is fixedly connected inside the storage hopper, and an air separation component is provided inside the storage hopper to separate the processed coarse grains from the bran.

[0009] The negative pressure adsorption component is used to discharge the sorted bran material, and one end of it is fixedly connected to the storage hopper through a connecting pipe.

[0010] The air separation component includes a mounting shell, which is fixedly embedded inside the storage hopper, and an induced draft fan is fixedly installed inside the mounting shell.

[0011] An air outlet is provided on one side wall of the mounting shell, and an isolation net is fixedly installed inside the air outlet to prevent coarse grains from falling into the mounting shell.

[0012] The air outlet is located below the sieve plate and is tilted upwards.

[0013] The negative pressure adsorption assembly includes a housing, which is fixedly connected to the top of the frame. A negative pressure fan is fixedly connected to one side of the housing, and the other side of the housing is fixedly connected to a connecting pipe.

[0014] A waste discharge pipe is fixedly connected to the top of the shell.

[0015] The forward / reverse switch is electrically connected to the motor section of the coaxial crusher body via a controller, and the forward / reverse switch switches the motor section of the coaxial crusher body to rotate in either direction according to the wear condition of the hammer section of the coaxial crusher body.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention provides flexible steering adjustment capabilities for equipment operation through the cooperation of a reversing switch and the coaxial crusher body. The reversing switch can directly control the forward and reverse rotation of the coaxial crusher body. When uneven wear of the hammers occurs, the direction can be switched without complicated operations. In addition, the combination of the screen plate and the air separation component in the storage hopper effectively achieves precise separation of coarse grains and bran. The screen plate uses the difference in aperture size to screen the crushed material, allowing granular coarse grains to fall through the screen plate while blocking bran above the screen plate. The airflow generated by the air separation component further separates the granules on the screen plate. The bran is blown up, and the two work together to form a dual separation mechanism, which greatly improves the separation efficiency and purity of the grain particles and bran, ensuring that the quality of the finished coarse grain meets the subsequent production standards. The connection design between the negative pressure adsorption component and the storage hopper provides a strong and stable power for the discharge of bran. The negative pressure adsorption component quickly sucks away and collects the bran separated in the storage hopper through the connecting pipe, avoiding the accumulation of bran in the storage hopper and causing secondary blockage. At the same time, it reduces the pollution of the production environment caused by the scattering of bran, improves the cleanliness of the production site, and further ensures the stability of equipment operation and production efficiency.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A multi-functional coaxial crusher with built-in forward and reverse steering includes: a frame 1, on the top of which a coaxial crusher body 2 is fixedly installed, and a forward / reverse switch 3 is installed on the top of the coaxial crusher body 2; a feed hopper 4, the bottom of which is fixedly connected to the hopper 5 of the coaxial crusher body 2; the bottom of the feed hopper 4 is fixedly connected to the hopper 5 of the coaxial crusher body 2, and coarse grains enter the hopper 5 for temporary storage through the feed hopper 4, and are then transported by the hopper 5 to the coaxial crusher body 2 for crushing; a storage hopper 6 is fixedly connected to the bottom of the hopper 5, and the crushed material directly enters the storage hopper 6. The side wall of the storage hopper 6 is provided with a discharge port for discharging the separated coarse grain particles, and a screen plate 7 is fixedly connected inside the storage hopper 6. The screen plate 7 is a double-layer stainless steel filter screen, which can improve the wear resistance and service life of the screen plate 7. The aperture of the screen plate 7 is matched with the particle size of the required coarse grain particles. By setting up a continuous structure of feeding hopper 4, silo 5, storage hopper 6 and sieve plate 7, the orderly flow of materials is achieved, and the sieve plate 7 is used to initially screen granular coarse grains and bran.

[0026] The storage hopper 6 is fixedly connected to the bottom of the silo 5. The side wall of the storage hopper 6 is provided with a discharge port. The inside of the storage hopper 6 is fixedly connected with a screen plate 7. The inside of the storage hopper 6 is provided with an air separation component 8 for separating the processed coarse grains from the bran. A negative pressure adsorption component 9 is used to discharge the separated bran, one end of which is fixedly connected to the storage hopper 6 through a connecting pipe 12. The combination of the screen plate 7 and the air separation component 8 in the storage hopper 6 effectively achieves precise separation of coarse grains and bran. The screen plate 7 uses the difference in aperture size to screen the crushed material, allowing the granular coarse grains to fall through the screen plate while blocking the bran above the screen plate 7. The airflow generated by the air separation component 8 further blows up the bran on the screen plate 7. The two work together to form a dual separation mechanism, which greatly improves the separation efficiency and purity of granular coarse grains and bran, ensuring that the quality of the finished coarse grains meets the subsequent production standards. The connection design between the negative pressure adsorption component 9 and the storage hopper 6 provides a strong and stable power for the discharge of bran. The negative pressure adsorption component 9 quickly sucks away and collects the bran separated in the storage hopper 6 through the connecting pipe 12, avoiding the accumulation of bran in the storage hopper 6 and causing secondary blockage. At the same time, it reduces the pollution of the production environment caused by the scattering of bran, improves the cleanliness of the production site, and further ensures the stability and production efficiency of the equipment operation.

[0027] This continuous material flow structure makes the entire process of coarse grains from entering the equipment to initial separation smooth and natural, reducing the residence time of materials in the equipment and unnecessary handling links. This not only improves production efficiency, but also reduces the risk of material contamination or damage during the flow process, providing a good foundation for subsequent fine processing.

[0028] The air separation component 8 includes a mounting housing 801, which is fixedly embedded inside the storage hopper 6, providing installation space for the induced draft fan 802. The induced draft fan 802 is fixedly installed inside the mounting housing 801, generating airflow when it operates. An air outlet is provided on one side wall of the mounting housing 801, located below the sieve plate 7 and inclined upward, which can blow an inclined upward airflow towards the sieve plate 7. An isolation net 10 is fixedly embedded inside the air outlet. By setting up the mounting housing 801, the induced draft fan 802, the inclined upward air outlet, and the isolation net 10, the effect of generating directional airflow to separate bran and coarse grains is achieved, while preventing coarse grains from falling into the mounting housing 801.

[0029] The negative pressure adsorption assembly 9 includes a housing 901, which is fixedly connected to the top of the frame 1 and is used to temporarily store the adsorbed bran. A negative pressure fan 902 is fixedly connected to one side of the housing 901, providing power for the adsorption of bran. The other side of the housing 901 is fixedly connected to the storage hopper 6 via a connecting pipe 12. A waste discharge pipe 11 is fixedly connected to the top of the housing 901 for discharging and collecting the bran inside the housing. By setting up the housing 901, the negative pressure fan 902, the connecting pipe 12, and the waste discharge pipe 11, the bran in the storage hopper 6 is quickly adsorbed and discharged, avoiding the accumulation and blockage of bran.

[0030] The forward / reverse switch 3 is electrically connected to the motor section of the coaxial crusher body 2 via the controller. The forward / reverse switch 3 can control the motor's forward and reverse rotation based on the wear condition of the hammer blades on the coaxial crusher body 2. By setting up a linkage structure between the forward / reverse switch, controller, and motor, the crushing direction can be flexibly adjusted, hammer blade wear can be balanced, and clogging of the chaff discharge can be addressed.

[0031] Working Principle: When this multi-functional coaxial pulverizer with built-in forward and reverse steering is working, coarse grains first enter the hopper 5 for temporary storage through the feed hopper 4. The hopper 5 then transports the coarse grains into the coaxial pulverizer body 2 for pulverization. The pulverized material falls directly into the storage hopper 6. Inside the storage hopper 6, the sieve plate 7 uses its aperture difference to perform preliminary screening of the material. Granular coarse grains fall through the aperture of the sieve plate 7 and are discharged from the outlet on the side wall of the storage hopper 6, while bran is blocked above the sieve plate 7. At this time, the air separation component 8 starts working, and the blower 802 generates airflow. The airflow is blown out from the upward-sloping air outlet on the side wall of the mounting shell 801, blowing up the bran on the sieve plate 7, further separating the bran from the coarse grains. Simultaneously, the negative pressure fan 902 in the negative pressure adsorption component 9 also starts operating, generating negative pressure within the housing 901. This negative pressure is then rapidly drawn into the housing 901 through the connecting pipe 12, temporarily storing the bran material blown up from the storage hopper 6. Finally, the bran material is discharged and collected through the waste discharge pipe 11. During equipment operation, the reversing switch 3 is electrically connected to the motor section of the coaxial crusher body 2 via a controller. Based on the wear condition of the hammer blades of the coaxial crusher body 2, the controller controls the motor's forward and reverse rotation. When the hammer blades wear unevenly, the reversing motor engages different parts of the hammer blades in the crushing process, balancing the wear. When encountering bran discharge blockage, the reversing motor uses reverse impact force and airflow changes to expel the blockage, ensuring normal equipment operation. Through the coordinated work of these components, the crusher achieves efficient crushing of coarse grains, precise separation of coarse grains and bran material, and timely discharge of bran material. Simultaneously, the reversing function extends the equipment's service life and improves production efficiency and product quality.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
