Description

Technical Field

[0001] The invention relates to the technical field of pulverization, and in particular to an ultrafine pulverization device for feed processing. Background Art

[0002] With the development of animal husbandry, the requirements for feed quality are increasing. The size of feed particles plays a key role in animal digestion and absorption. Ultrafine grinding of feed can significantly improve feed utilization, reduce animal feces excretion, reduce breeding costs and benefit the environment.

[0003] Most of the existing feed crushing devices are knife-type crushers. In knife-type crushers, a main shaft is set in the crushing chamber, and a cutter is installed on the main shaft. The main shaft and the cutter on the main shaft are driven by a drive motor to rotate, thereby crushing the raw materials. In the actual crushing operation, it is difficult to adjust the feeding speed according to the saturation amount of the material in the crushing chamber. Once a large amount of material flows into the crushing chamber during feeding, not only will the space of the crushing chamber be excessively occupied, but the material will lack sufficient space for turning and dispersion during the crushing process, making it impossible for the cutter to effectively contact each material particle, which will lead to a decrease in crushing efficiency and even cause blockage inside the crushing chamber, completely paralyzing the entire crushing device.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] The embodiment of the present application discloses an ultrafine grinding device for feed processing.

[0030] Please refer to Figures 1 to 8 In one embodiment of the present application, a feed processing ultrafine grinding device includes a body 100, which is fixedly mounted on a frame 104. A grinding chamber 101 is provided inside the body 100, and a grinding assembly 200 rotatably connected to the body 100 is provided inside the grinding chamber 101. A first negative pressure suction assembly 300 communicating with the grinding chamber 101 is provided on the top of the body 100, and a second negative pressure suction assembly 400 communicating with the grinding chamber 101 is provided on the bottom of the body 100, and a filter assembly 500 is provided between the second negative pressure suction assembly 400 and the grinding chamber 101; a saturation detection mechanism 600 is provided on the grinding assembly 200, an automatic adjustment mechanism 700 is provided on the first negative pressure suction assembly 300, and the automatic adjustment mechanism 700 is connected to the saturation detection mechanism 600, and a manual adjustment mechanism 800 is provided on the second negative pressure suction assembly 400.

[0031] The implementation principle of a feed processing ultrafine grinding device in the embodiment of the present application is: First, the feed raw materials are sucked into the crushing chamber 101 by the first negative pressure suction component 300. After entering the crushing chamber 101, the feed raw materials are crushed under the action of the crushing component 200. The crushed material will move to the second negative pressure suction component 400, and during the movement, it will first pass through the filter component 500. The filter component 500 plays a screening role. It can intercept larger particles that do not meet the ultrafine grinding requirements, so that the larger particles continue to remain in the crushing chamber 101 and are crushed by the crushing component 200. Only materials that meet the ultrafine grinding standards can pass through the filter component 500. The ultrafinely crushed feed after passing through the filter component 500 is sucked out of the crushing chamber 101 under the action of the second negative pressure suction component 400, completing the entire crushing process and discharging.

[0032] During operation, the saturation detection mechanism 600 can detect the saturation of the raw materials of the feed inside the crushing chamber 101 by detecting the load of the crushing assembly 200. When the saturation detection mechanism 600 detects that the crushing assembly 200 is close to saturation, it will drive the automatic adjustment mechanism 700 to adjust the first negative pressure suction assembly 300, thereby reducing the feeding speed of the first negative pressure suction assembly 300. At the same time, the manual adjustment mechanism 800 is set on the second negative pressure suction assembly 400. The operator can control the working state of the second negative pressure suction assembly 400 through the manual adjustment mechanism 800, which can flexibly control the discharge of the crushed material in the debugging stage of the equipment or according to the specific discharge requirements of the product.

[0033] The present application can effectively solve the problem of easy clogging of the grinding device through the mutual cooperation of the saturation detection mechanism 600 and the automatic adjustment mechanism 700, improve the grinding efficiency, and thus meet the needs of modern feed processing enterprises for high-quality ultrafine grinding feed.

[0034] Please refer to Figures 1 to 8 In a specific embodiment of the present application, the crushing assembly 200 includes a main shaft 201, which is rotatably connected to the body 100 and passes through the center of the crushing chamber 101. Two mounting disks 202 symmetrically arranged at the two ends of the crushing chamber 101 are fixedly connected to the main shaft 201. One end of the main shaft 201 passing through the body 100 is transmission-connected with a driving member 203. A plurality of annularly distributed first mounting shafts 204 are installed between the two mounting disks 202. The plurality of first mounting shafts 204 and the saturation detection mechanism 600 are evenly distributed in annular shapes on the mounting disk 202. The first mounting shafts 204 are rotatably connected to a plurality of first crushing knives 205 arranged in parallel.

[0035] During operation, the driving member 203 provides power for the entire crushing assembly 200. The power of the driving member 203 is transmitted to the main shaft 201 through a transmission connection, so that the main shaft 201 rotates on the body 100 around an axis that passes through the center of the crushing chamber 101. The rotation of the main shaft 201 drives the two mounting disks 202 fixed thereon to rotate synchronously. The multiple first mounting shafts 204 installed between the two mounting disks 202 will rotate with the mounting disks 202. Since the first mounting shaft 204 is rotatably connected to a plurality of first crushing knives 205 arranged in parallel, when the first mounting shaft 204 rotates, the first crushing knives 205 will also rotate accordingly. When the feed material enters the crushing chamber 101, these first crushing knives 205 rotating at high speed will cut and impact the feed. The first crushing knives 205 cooperate with each other, and the multiple first crushing knives 205 are arranged in parallel on the first installation shaft 204, and the multiple first installation shafts 204 are distributed in an annular manner, so that the feed can be subjected to cutting and impact forces from different directions in the crushing chamber 101, thereby effectively crushing the feed particles.

[0036] Please refer to Figures 1 to 8 In a specific embodiment of the present application, a first limiting ring 206 is installed between two adjacent first crushing knives 205, and the first limiting ring 206 can limit the position of the first crushing knives 205. During the high-speed rotation of the first crushing knives 205, the first limiting ring 206 can prevent the first crushing knives 205 from axial displacement during the working process, ensuring that the position of the first crushing knives 205 is relatively stable, thereby ensuring the stable operation of the crushing work.

[0037] Please refer to Figures 1 to 8 In a specific embodiment of the present application, the driving member 203 is configured as an electric motor, preferably a three-phase asynchronous motor, which has a simple structure, reliable operation, and convenient maintenance. It can provide stable power output and is suitable for long-term operation. For example, the Y90L-2 motor in the Y series three-phase asynchronous motor has a power of 2.2kW and a rated speed of about 2840r / min, which can provide sufficient power for the feed grinder and is suitable for crushing corn, wheat and other cereal feeds.

[0038] Please refer to Figures 1 to 8 In a specific embodiment of the present application, the first negative pressure suction component 300 includes a first negative pressure fan 301, which is installed on the top of the body 100, and a three-way pipe 302 is installed at the air inlet end of the first negative pressure fan 301. The vertically upward end of the three-way pipe 302 is connected to the automatic adjustment mechanism 700, and the other end of the three-way pipe 302 is connected to a feed pipe 303, and the end of the feed pipe 303 away from the three-way pipe 302 is connected to a storage tank 304, and the exhaust end of the first negative pressure fan 301 is connected to the crushing chamber 101.

[0039] During operation, after the first negative pressure fan 301 is started, a pressure difference is generated between its exhaust end and air inlet end, the exhaust end is connected to the crushing chamber 101, and the air inlet end is connected to the three-way pipe 302. Due to the operation of the fan, a negative pressure environment is formed at the air inlet end. This negative pressure environment extends to the storage tank 304 through the feed pipe 303. Under the pressure difference between the external atmospheric pressure and the negative pressure at the three-way pipe 302, the feed in the storage tank 304 is sucked into the feed pipe 303. Driven by the negative pressure, the feed moves toward the air inlet end of the first negative pressure fan 301 along the feed pipe 303 and the three-way pipe 302. The vertically upward end of the three-way pipe 302 is connected to the automatic adjustment mechanism 700. When the saturation detection mechanism 600 detects that the crushing assembly 200 is close to the saturation state, the automatic adjustment mechanism 700 can adjust the feeding speed by changing the opening size of the upward end of the three-way pipe 302. If the feed amount needs to be reduced, the automatic adjustment mechanism 700 can increase the opening at the upper end to reduce the suction force in the feed pipe 303, thereby reducing the speed at which the feed enters the grinding chamber 101.

[0040] Please refer to Figures 1 to 8 In a specific embodiment of the present application, the second negative pressure suction component 400 includes a discharge hopper 401, which is fixedly installed at the bottom of the body 100, and the discharge hopper 401 is connected to the crushing chamber 101 through the filter component 500. A discharge pipe 402 is fixedly installed at one end of the discharge hopper 401 away from the crushing chamber 101, and a second negative pressure fan 403 is connected to the end of the discharge pipe 402 away from the discharge hopper 401. A discharge bin 404 is connected to the second negative pressure fan 403, and a discharge port 405 is provided at the bottom of the discharge bin 404.

[0041] During operation, after the second negative pressure fan 403 is started, a negative pressure environment will be formed in the discharge pipe 402 and the discharge hopper 401. Since the discharge hopper 401 is connected to the grinding chamber 101 and the filter assembly 500 is separated, the ultrafinely ground feed in the grinding chamber 101 after being ground and filtered will move to the discharge hopper 401 under the action of the pressure difference. First, the materials in the grinding chamber 101 that meet the ultrafine grinding standard pass through the filter assembly 500 and enter the discharge hopper 401. Under the negative pressure generated by the second negative pressure fan 403, these materials will enter the discharge pipe 402 along the discharge hopper 401 and be transported to the discharge bin 404. After the materials enter the discharge bin 404, they are finally discharged from the discharge port 405 at the bottom of the discharge bin 404. The discharge port 405 can perform corresponding discharge operations as needed, for example, it can be connected to packaging bags, conveying equipment, etc., and the ultrafinely ground feed can be subsequently packaged, stored or further processed.

[0042] Please refer to Figures 1 to 8In a specific embodiment of the present application, the filter assembly 500 includes a filter mounting frame 501, and the inner wall of the body 100 is located at the lower part of the crushing chamber 101 and is provided with two groups of obliquely symmetrical slide grooves 502, the filter mounting frame 501 is slidably connected inside the slide groove 502, and a filter 503 is fixedly installed on the filter mounting frame 501.

[0043] During operation, when the material in the pulverizing chamber 101 moves toward the second negative pressure material suction component 400 after being pulverized, the material will first contact the filter component 500 .

[0044] When the material passes through the filter 503 , since the mesh size of the filter 503 is set according to the requirements of ultrafine grinding, only fine particles that meet the ultrafine grinding standards can pass through the filter 503 , while larger particles will be intercepted above the filter 503 .

[0045] The filter mounting frame 501 is slidably connected in the slide groove 502 on the inner wall of the body 100. The obliquely symmetrically arranged slide groove 502 allows the filter mounting frame 501 to slide within a certain range. When the filter 503 needs to be cleaned or replaced, the filter mounting frame 501 can be slid out of the slide groove 502, which is convenient for operators to operate the filter 503.

[0046] Please refer to Figures 1 to 8 In a specific embodiment of the present application, the saturation detection mechanism 600 includes a second mounting shaft 601, a waist-shaped hole 602 is opened on the mounting disk 202 along the radial direction of the mounting disk 202, a sliding frame 603 is slidably connected inside the waist-shaped hole 602, the automatic adjustment mechanism 700 is transmission-connected to the sliding frame 603, the two ends of the second mounting shaft 601 are installed on two sliding frames 603, a plurality of second crushing knives 604 arranged in parallel are rotatably connected to the second mounting shaft 601, and a second limiting ring 605 is installed between two adjacent second crushing knives 604.

[0047] During operation, the two ends of the second mounting shaft 601 are mounted on two sliding frames 603, and the sliding frames 603 are slidably connected inside the waist-shaped hole 602 on the mounting plate 202. This means that the second mounting shaft 601 can move radially within the range of the waist-shaped hole 602 through the sliding frames 603.

[0048] A plurality of second crushing knives 604 arranged in parallel are rotatably connected to the second mounting shaft 601. When the driving member 203 drives the main shaft 201 and the mounting disk 202 to rotate, under the action of centrifugal force, the sliding frame 603, the second mounting shaft 601 and the second crushing knives 604 move along the radial direction of the mounting disk 202 in a direction away from the center of the mounting disk 202, thereby driving the second crushing knives 604 to cooperate with the first crushing knife 205 to crush the feed in the crushing chamber 101.

[0049] During the pulverizing process, when the amount of feed in the pulverizing chamber reaches a certain level, a greater resistance will be generated to the rotation of the second pulverizing blade 604, thereby overcoming the effect of the centrifugal force on the second pulverizing blade 604, so that the second pulverizing blade 604 moves along the radial direction of the mounting plate 202 toward the center of the mounting plate 202. Since the sliding frame 603 is connected to the second pulverizing blade 604 through the second mounting shaft 601, the position of the sliding frame 603 in the waist-shaped hole 602 will change. The change in the position of the sliding frame 603 can indirectly reflect the saturation of the material in the pulverizing chamber 101, thereby realizing the detection of the saturation of the material in the pulverizing chamber 101.

[0050] Please refer to Figures 1 to 8 In a specific embodiment of the present application, the automatic adjustment mechanism 700 includes a push rod 701, a sliding hole 702 penetrating the main shaft 201 is opened on the mounting disk 202 and is located inside the waist-shaped hole 602 along the radial direction of the mounting disk 202, the push rod 701 is slidably connected inside the sliding hole 702, the push rod 701 is fixedly connected to the sliding frame 603, the end of the push rod 701 away from the sliding frame 603 is fixedly connected to the spring 703, the end of the spring 703 away from the push rod 701 is fixedly connected to the main shaft 201, an air flow channel 704 connected to the sliding hole 702 is opened inside the main shaft 201 along its axial direction, a valve hole 705 is opened on the push rod 701 corresponding to the air flow channel 704, one end of the air flow channel 704 is connected to a dust cover 706, and the end of the air flow channel 704 away from the dust cover 706 is connected to the three-way pipe 302.

[0051] During operation, when the saturation of the material in the crushing chamber 101 changes, the sliding frame 603 moves along the waist-shaped hole 602, which drives the push rod 701 to move in the sliding hole 702. One end of the spring 703 is fixed on the main shaft 201, and the other end is fixed on the push rod 701. Under normal circumstances, the spring 703 applies a certain elastic force to the push rod 701, so that the valve hole 705 on the push rod 701 remains in a position that coincides with the air flow channel 704. During the crushing process, when the sliding frame 603 moves under the action of centrifugal force, the spring 703 will be stretched, and the position of the valve hole 705 relative to the air flow channel 704 will change, thereby affecting the air flow rate in the air flow channel 704. One end of the air flow channel 704 is connected to the dust cover 706, and the other end is connected to the three-way pipe 302. By changing the position of the valve hole 705, the size and direction of the air flow in the air flow channel 704 can be adjusted, thereby affecting the air pressure inside the feed pipe 303 connected to the three-way pipe 302.

[0052] During the crushing process, when the material inside the crushing chamber 101 is less than the material saturation, the sliding frame 603 will move to the outermost end under the action of centrifugal force, and the valve hole 705 will remain staggered with the air flow channel 704, so that the push rod 701 will block the air flow channel 704, thereby increasing the suction force inside the feed pipe 303, which will increase the feed speed. When the material inside the pulverizing chamber 101 is equal to or greater than the material saturation, the sliding frame 603 will retract to the position where the valve hole 705 and the air flow channel 704 intersect under the action of the spring 703, and the push rod 701 will connect the air flow channel 704, thereby allowing the external air to enter the first negative pressure fan 301 through the dust cover 706, the air flow channel 704, and the three-way pipe 302. On the one hand, the entry of external air can reduce the suction force inside the feed pipe 303, thereby reducing the feed speed; on the other hand, the external air can also take away the heat generated by the pulverizing component 200 during operation through the air flow channel 704, which is beneficial to cooling the pulverizing component 200.

[0053] Please refer to Figures 1 to 8 In a specific embodiment of the present application, a heat-conducting box 707 is installed between the two mounting plates 202 and the inner wall of the body 100, and a sound-absorbing material layer is solidly bonded to the inner wall of the heat-conducting box 707. The heat-conducting box 707 is fixedly installed on the body 100, and the main shaft 201 is sealed and rotatably connected to the heat-conducting box 707. The outer side of the main shaft 201 is located inside the heat-conducting box 707. A first vent 708 connected to the air flow channel 704 is opened, and a second vent 709 penetrating the heat-conducting box 707 is opened on the body 100. The dust cover 706 is fixedly installed on the body 100 at a position corresponding to one of the second vents 709, and a connecting pipe 710 is installed on the body 100 at a position corresponding to another second vent 709, and the other end of the connecting pipe 710 is connected to the three-way pipe 302.

[0054] During operation, a first vent hole 708 is provided on the outer side of the main shaft 201 at a position inside the heat conduction box 707, and the first vent hole 708 is connected to the air flow channel 704 inside the main shaft 201. A second vent hole 709 provided on the body 100 penetrates the heat conduction box 707. Figure 3 As shown by the arrows in the figure, external air can enter the interior of the three-way pipe 302 through the dust cover 706, the second air vent 709 close to the dust cover 706, the heat conduction box 707 close to the dust cover 706, the first air vent 708 close to the dust cover 706, the air flow channel 704, the first air vent 708 close to the connecting pipe 710, the heat conduction box 707 close to the connecting pipe 710, the second air vent 709 close to the connecting pipe 710, and the connecting pipe 710 in sequence.

[0055] The heat-conducting box 707 is installed between the mounting plate 202 and the inner wall of the machine body 100. When the crushing assembly 200 is working, the high-speed operation of the mounting plate 202, the main shaft 201, the first crushing blade 205, the second crushing blade 604 and other components will generate heat, which will be transferred to the heat-conducting box 707. The heat-conducting box 707 plays a role in conducting the heat away, which helps to further improve the heat dissipation effect inside the crushing chamber 101 and avoid the feed quality or equipment performance affected by excessive temperature.

[0056] The sound-absorbing material layer bonded to the inner wall of the heat-conducting box 707 can effectively absorb the noise generated during the crushing process. When the first crushing blade 205 and the second crushing blade 604 cut and hit the feed, and the friction between the components generates noise, the sound-absorbing material layer will convert part of the noise energy into other forms of energy such as heat energy, thereby reducing the noise level generated when the equipment is running.

[0057] In a specific embodiment of the present application, the sound-absorbing material layer uses a material with good sound absorption performance, such as glass fiber, rock wool, polyurethane foam, etc. There are a large number of tiny pore structures inside these materials. When the sound waves generated by the operation of the equipment are transmitted to the sound-absorbing material layer, the sound propagates in the tiny pores inside the material. The air molecules rub against the fibers or pore walls of the sound-absorbing material in the pores. At the same time, due to the air vibration caused by the sound, viscosity will also occur between the air molecules. These frictions and viscosity will convert sound energy into heat energy, thereby gradually attenuating the energy of the sound. The sound-absorbing material layer is fixed to the inner wall of the heat-conducting box 707 by bonding. This installation method can ensure that the sound-absorbing material fits tightly with the heat-conducting box 707 to avoid gaps that affect the sound absorption effect. In addition, the bonding method is relatively simple and easy to operate during the equipment assembly process.

[0058] Please refer to Figures 1 to 8 In a specific embodiment of the present application, a threaded hole 606 is provided on the mounting plate 202 at one end of the sliding frame 603 which is located inside the waist-shaped hole 602 and is away from the center of the mounting plate 202 , and a limiting column 607 is threadedly connected to the mounting plate 202 through the threaded hole 606 .

[0059] During operation, when the sliding frame 603 slides in the waist-shaped hole 602, the limiting column 607 is threadedly connected to the mounting plate 202 through the threaded hole 606 and is located at a corresponding position of the sliding frame 603 away from the center of the mounting plate 202. As the sliding frame 603 slides in a direction away from the center of the mounting plate 202, it will eventually contact the limiting column 607. At this time, the limiting column 607 blocks the sliding frame 603 from continuing to slide in this direction, thereby limiting the moving range of the sliding frame 603 in the waist-shaped hole 602. The operator can change the extension length of the limiting column 607 on the mounting plate 202 by rotating the limiting column 607 and utilizing the characteristics of the threaded connection. When the limiting column 607 is screwed out more toward the outside of the mounting plate 202, the sliding distance of the sliding frame 603 is relatively increased; conversely, when the limiting column 607 is screwed in more toward the inside of the mounting plate 202, the sliding distance of the sliding frame 603 is relatively reduced. In this way, the intersection degree between the valve hole 705 and the air flow channel 704 can be adjusted, thereby determining the air flow required to ensure heat dissipation of the pulverizing device during normal operation.

[0060] Please refer to Figures 1 to 8 In a specific embodiment of the present application, the manual adjustment mechanism 800 includes an air inlet 801 opened on the discharge hopper 401, and the discharge hopper 401 is rotatably connected to the air inlet 801 corresponding to the air inlet 801, and the air duct sealing plate 802 is fixedly connected to the air duct sealing plate 802.

[0061] During operation, when the second negative pressure suction component 400 is working, negative pressure exists in the discharge hopper 401, and the crushed and filtered feed in the crushing chamber 101 is sucked out. The air inlet 801 is connected to the outside atmosphere, and the air duct sealing plate 802 is rotatably connected to the position of the air inlet 801 on the discharge hopper 401. When the operator turns the adjustment handle 803, the air duct sealing plate 802 is driven to rotate. During the rotation of the air duct sealing plate 802, the opening size of the air inlet 801 will change. The change in the opening size of the air inlet 801 will affect the amount of air entering the discharge hopper 401, and then change the size of the negative pressure in the discharge hopper 401. The change in negative pressure will affect the speed and flow rate of feed discharge.

[0062] When the air duct sealing plate 802 rotates to increase the opening of the air inlet 801, more air enters the discharge hopper 401, the negative pressure in the discharge hopper 401 decreases, and the feed discharge speed slows down; conversely, when the opening of the air inlet 801 decreases, the negative pressure in the discharge hopper 401 increases, and the feed discharge speed speeds up.

[0063] Please refer to Figures 1 to 8 In a specific embodiment of the present application, a symmetrically arranged inspection opening 102 is opened on the side wall of the body 100 corresponding to the filter assembly 500 and the crushing assembly 200, and an inspection door 103 is installed on the body 100 corresponding to the inspection opening 102.

[0064] During operation, when the filter assembly 500 or the crushing assembly 200 fails, requires maintenance or parts replacement, the maintenance personnel can open the inspection door 103 and operate the corresponding assembly through the inspection port 102. For example, if the filter 503 is clogged and needs to be cleaned, the maintenance personnel can open the inspection door 103 on the side of the corresponding filter assembly 500, reach in through the inspection port 102, and slide the filter mounting frame 501 out of the slide slot 502 for cleaning; if the first crushing blade 205 or the second crushing blade 604 in the crushing assembly 200 is worn, the maintenance personnel can open the inspection door 103 on the side of the corresponding crushing assembly 200 to replace the first crushing blade 205 or the second crushing blade 604.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
