Description

Technical Field

[0001] This utility model relates to the technical field of feed additive processing equipment, and in particular to a multi-component feed additive processing and mixing equipment. Background Technology

[0002] In animal husbandry, a large amount of feed is usually used. When using feed, feed additives are often added to make the feed more nutritious and medicinal, which is more beneficial to the growth of livestock. Feed additives refer to small or trace amounts of substances added during the production, processing and use of feed. They are divided into solid additives and liquid additives. They are used in very small amounts in feed but have significant effects. Feed additives are an essential raw material used in the modern feed industry.

[0003] Existing feed additive mixing chambers are mechanical devices that use mechanical force and gravity to uniformly mix two or more materials. When mixing different components of feed additives, a powder pulverizer is required to grind and crush the different additive raw materials. The purpose is to adjust the particle size, improve digestibility, and better absorb the nutrients in the feed additives. Furthermore, different additive components are measured before being added to the mixer for mixing, which greatly reduces the production efficiency of feed additives. The mixing speed is slow and the mixing effect is poor. If the external air is humid, the feed additive particles in the mixing chamber are prone to moisture accumulation and clumping while waiting for another feed additive to be crushed, which in turn affects the subsequent mixing of different additive particles. Utility Model Content

[0004] To address the existing technical problems of low mixing efficiency and easy accumulation and clumping of feed additive particles in the storage chamber when the external air is humid, this utility model provides a multi-component feed additive processing and mixing equipment.

[0005] The technical solution of this utility model is achieved through the following scheme: a multi-component feed additive processing and mixing equipment, including a support frame, a mixing cylinder, a grinding component, an airflow disturbance component, and a mixing device. The mixing cylinder is mounted on the support frame, and a quantitative feeding and crushing component is mounted on the mixing cylinder. The grinding component, the airflow disturbance component, and the mixing device are arranged sequentially from top to bottom inside the mixing cylinder. A heating sleeve is fitted on the mixing cylinder, and a temperature sensor and a pressure sensor are installed through the mixing cylinder. The quantitative feeding and crushing component is connected to the grinding component. A discharge port is opened on the bottom surface of the mixing cylinder, and an electric valve is installed on the discharge port.

[0006] By integrating functions such as quantitative feeding crushing, grinding, airflow disturbance mixing, and agitation mixing into the mixing drum, continuous operation is achieved, eliminating intermediate waiting and transfer steps, and shortening the production cycle. The grinding component, in conjunction with the quantitative feeding crushing component, crushes and grinds the added feed additive raw materials, reducing the problem of uneven mixing caused by differences in particle size. The airflow disturbance component, in conjunction with the agitation mixing device, causes the feed additive particles to continuously tumble and collide, breaking up the aggregation between particles and promoting the uniform dispersion of each component. Based on the data feedback from the sensors, timely adjustments are made to ensure that the environment inside the drum is always within a suitable range. The heating sleeve heats the agitation zone of the mixing drum to prevent the material from getting damp and clumping, ensuring the normal operation of the agitation mixing device and improving the quality and stability of the product.

[0007] Preferably, the quantitative feeding crushing assembly includes a support shell, an electronic weighing pan, and crushing rollers. The support shell is detachably installed on the mixing drum. A third drive motor is provided on the outer surface of the support shell. The electronic weighing pan is rotatably installed inside the support shell via the third drive motor. Several crushing rollers are also rotatably installed inside the support shell, and the several crushing rollers are located directly below the electronic weighing pan.

[0008] Preferably, the airflow disturbance component includes a filter box, an air duct, and a support column. The filter box is equipped with an air pump, which is connected to the support column through the air duct. The support column is equipped with an air channel, a material inlet slope is provided on the upper surface of the support column, and a plurality of nozzles are provided on the lower surface of the support column. The air outlet end of the nozzle is equipped with a filter screen.

[0009] Preferably, the mixing device includes a second drive motor, a stirring fan, a scraper, and a scraper fan. The second drive motor is fixedly installed on the bottom surface of the mixing cylinder, and a rotating shaft is installed on the drive end of the second drive motor. The stirring fan, the scraper, and the scraper fan are installed on the rotating shaft from top to bottom. The scraper abuts against the inner wall of the mixing cylinder, and the scraper fan is adapted to the material feeding area at the bottom of the inner cavity of the mixing cylinder.

[0010] Preferably, the mixing cylinder is equipped with a mesh plate isolation box, and the temperature sensor and the air pressure sensor are located inside the mesh plate isolation box.

[0011] Preferably, the grinding assembly includes a first drive motor, a male grinding head, and a female grinding head. A guide ring is fixedly installed on the top of the female grinding head. The drive end of the first drive motor passes through the mixing cylinder and is connected to the male grinding head. The male grinding head and the female grinding head cooperate with each other.

[0012] Preferably, the heating sleeve flange is connected to the support frame, and a heating plate is provided inside the heating sleeve.

[0013] In summary, this utility model has the following beneficial effects: 1. This utility model integrates functions such as quantitative feeding crushing, grinding, airflow disturbance mixing, and agitation mixing into a mixing drum, achieving continuous operation, eliminating intermediate waiting and transfer steps, and shortening the production cycle. The grinding component, in conjunction with the quantitative feeding crushing component, crushes and grinds the added feed additive raw materials, reducing uneven mixing caused by differences in particle size. The airflow disturbance component, in conjunction with the agitation mixing device, causes the feed additive particles to continuously tumble and collide, breaking up particle aggregation and promoting uniform dispersion of each component, ensuring uniformity and consistency of the mixing effect. Based on sensor feedback data, timely adjustments are made to ensure the internal environment of the drum remains within a suitable range. A heating sleeve heats the mixing zone of the mixing drum to prevent material from becoming damp and clumping, ensuring the normal operation of the agitation mixing device and improving product quality and stability.

[0014] 2. By integrating metering and preliminary crushing functions, material transfer and intermediate links are reduced, and the production cycle is shortened. The electronic weighing pan accurately weighs the material, and the third drive motor drives the electronic weighing pan to rotate, so that all the raw materials on the electronic weighing pan fall into the crushing roller below for crushing, reducing raw material residue. The preliminary crushing by the crushing roller below prepares the material for grinding.

[0015] 3. Multiple nozzles agitate the powder in the mixing drum from multiple directions, causing the powder to move within the drum and preventing stratification or clumping caused by powder remaining in the same position for too long, thus improving the uniformity of powder mixing; the feed slope reduces the accumulation of powder on the surface of the support column as it descends; the filter box and filter screen work together to perform dual filtration of the airflow, preventing impurities from the outside air from being mixed in with the airflow and ensuring product quality.

[0016] 4. By using a stirring fan, scraper, and scraper fan in tandem, the intensity and range of mixing are increased, ensuring that the powder is fully mixed in the mixing drum and improving mixing efficiency. The scraper and scraper fan effectively solve the problem of powder accumulating and clumping on the inner wall of the mixing drum and in the feeding area, ensuring continuous and stable operation of the device. Furthermore, during discharge, the scraper fan can push the powder to flow quickly and smoothly into the discharge port, improving discharge efficiency and avoiding blockage of the powder during the discharge process.

[0017] 5. The mesh plate isolation box avoids direct contact and impact of powder on the sensor, improving the sensor's service life; the guide ring accurately guides the raw material falling from above to the grinding area between the male and female grinding heads, where it is efficiently ground in the gap between the male and female grinding heads, turning the raw material into fine and uniform powder, thus improving grinding efficiency and quality.

[0020] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] A multi-component feed additive processing and mixing equipment, such as Figures 1-7As shown, the device includes a support frame 1, a mixing cylinder 2, a grinding assembly 3, an airflow disturbance assembly 4, and a mixing device 5. The mixing cylinder 2 is mounted on the support frame 1. A metering feed crushing assembly 7 is mounted on the mixing cylinder 2. A sealing cap is fitted to the opening at the top of the mixing cylinder 2, and the cap has a through hole adapted to the metering feed crushing assembly 7, allowing the metering feed crushing assembly 7 to connect to the interior of the mixing cylinder 2. Inside the mixing cylinder 2, from top to bottom, are the grinding assembly 3, the airflow disturbance assembly 4, and the mixing device 5. A heating sleeve 6 is fitted onto the mixing cylinder 2. A temperature sensor 10 and a pressure sensor 11 are installed through the mixing cylinder 2. The crushing component 7 is connected to the grinding component 3. The grinding component 3 is located in the inner cavity of the mixing cylinder 2 directly below the quantitative feeding crushing component 7. The feed additives are quantitatively fed and initially crushed from the quantitative feeding crushing component 7 and then enter the grinding component 3 for grinding. The bottom surface of the mixing cylinder 2 is provided with a discharge port 12, and an electric valve 13 is provided on the discharge port 12. Preferably, there are two discharge ports 12. The airflow disturbance component 4 causes the ground feed additives to circulate in the mixing cylinder 2 through airflow, which enhances the mixing effect between different feed additives, helps to distribute heat evenly, and avoids accumulation caused by staying in the same part for too long.

[0023] like Figure 5 As shown, a mesh plate isolation box 9 is provided inside the mixing drum 2, located on the side wall of the mixing drum 2 below the grinding assembly 3. The upper surface of the mesh plate isolation box 9 is an inclined sliding plate without filter mesh holes to ensure that the ground feed additives can slide down smoothly. The temperature sensor 10 and the air pressure sensor 11 are located inside the mesh plate isolation box 9. The mesh plate isolation box 9 provides a relatively stable monitoring environment for the temperature sensor 10 and the air pressure sensor 11, which is not directly affected by the material. It monitors the internal temperature and air pressure of the mixing drum 2 in real time to avoid high internal temperature or high air pressure, thereby shutting down the heating plate inside the heating sleeve 6 or the air pump of the airflow disturbance assembly 4.

[0024] like Figure 7As shown, the quantitative feeding crushing assembly 7 includes a support shell 71, an electronic weighing pan 73, and crushing rollers 74. The support shell 71 is detachably mounted on the mixing drum 2. A third drive motor 72 is provided on the outer surface of the support shell 71. The electronic weighing pan 73 is rotatably mounted inside the support shell 71 via the third drive motor 72. Several crushing rollers 74 are also rotatably mounted inside the support shell 71, located directly below the electronic weighing pan 73. The support shell 71 is screwed onto the cover. The drive end of the third drive motor 72 passes through the support shell 71 and is connected to one end of the electronic weighing pan 73. The other end of the electronic weighing pan 73 is connected to the support shell 71 via a rotating shaft. The part of the rotating shaft connected to the support shell 71 is provided with a bearing to ensure that the electronic weighing pan 73 can rotate smoothly. Preferably, there are two crushing rollers 74, which rotate inward relative to each other and are driven by two servo motors to quantitatively monitor feed additives. After preliminary crushing, the feed additive particles become smaller, which allows for smoother grinding in the subsequent grinding process and improves grinding efficiency.

[0025] When adding feed additives, the amount added can be accurately measured using the electronic weighing pan 73, ensuring that the quantity of feed additives added each time is accurate, meeting the formula requirements in the production process, and guaranteeing the consistency of product quality.

[0026] like Figure 3 and Figure 4 As shown, the airflow disturbance component 4 includes a filter box 41, an air duct 42, and a support column 43. The filter box 41 is equipped with an air pump, which is covered by the filter box 41 and installed on the platform of the support frame 1. The air pump is connected to the support column 43 through the air duct 42. The support column 43 is equipped with an air duct. The upper surface of the support column 43 is equipped with a material guiding slope, which is triangular in shape to avoid the accumulation of material powder. The lower surface of the support column 43 is equipped with several nozzles, which are connected to the air duct. The air outlet end of the nozzle is equipped with a filter screen. The support column 43 is cross-shaped and installed in the mixing cylinder 2. The cross shape has good stability. The nozzles close to the inner cavity of the mixing cylinder 2 are set at an angle and blow towards the inner wall of the mixing cylinder 2, effectively disturbing the material near the inner wall of the mixing cylinder 2 and improving the uniformity of mixing. The filter screen at the air outlet end of the nozzle and the filter box 41 covering the air pump provide double filtration of the airflow to prevent impurities from entering. The filter screen can also make the airflow more evenly dispersed.

[0027] like Figure 3 and Figure 4As shown, the mixing device 5 includes a second drive motor 51, a stirring fan 52, a scraper 53, and a scraper 54. The second drive motor 51 is fixedly installed on the bottom surface of the mixing cylinder 2. The connection between the motor and the bottom surface of the mixing cylinder 2 should be a reliable fixing method, such as bolt connection. A rotating shaft is installed on the drive end of the second drive motor 51. The stirring fan 52, scraper 53, and scraper 54 are installed sequentially on the rotating shaft from top to bottom. The scraper 53 abuts against the inner wall of the mixing cylinder 2, effectively scraping off the powder adhering to the inner wall. The scraper 53 has a sloping end to prevent powder accumulation. The scraper 53 is preferably made of wear-resistant and corrosion-resistant material, such as rubber or polyurethane. The scraper fan 54 is adapted to the material inlet area at the bottom of the mixing cylinder 2. There are two stirring fans 52. The material inlet area at the bottom of the mixing cylinder 2 is frustum-shaped, and the scraper fan 54 is in close contact with it. The two discharge ports 12 are located on both sides of the second drive motor 51 and close to the sloping part of the material inlet area of ​​the mixing cylinder 2. When discharging, the scraper fan 54 pushes the powder to flow quickly into the discharge port 12.

[0028] like Figure 1 , Figure 2 , Figure 5 and Figure 4 As shown, the heating sleeve 6 is connected to the support frame 1 via a flange. The heating sleeve 6 has a heating plate inside. The heating sleeve 6 is fitted onto the lower half of the mixing cylinder 2. The heating sleeve 6 is cylindrical, and its inner diameter is slightly larger than the outer diameter of the lower half of the mixing cylinder 2 to ensure that it can be smoothly fitted onto the mixing cylinder 2. At the same time, it ensures that there is a suitable gap between the two for installing the heating plate and forming a good heat exchange space to heat the mixing zone of the mixing cylinder 2 and prevent it from getting damp and clumping.

[0029] like Figure 3 , Figure 4 and Figure 6 As shown, the grinding assembly 3 includes a first drive motor 31, a male grinding head 32, and a female grinding head 33. A guide ring 8 is fixedly installed on the top of the female grinding head 33. The guide ring 8 guides the powder to accurately enter the grinding area. The first drive motor 31 is screwed onto the cover. The drive end of the first drive motor 31 passes through the mixing cylinder 2 and is connected to the male grinding head 32. The male grinding head 32 and the female grinding head 33 cooperate with each other, forming a grinding gap between them. The male grinding head 32 is provided with a feed screw groove and a grinding blade. The female grinding head 33 is provided with a main blade and a grinding blade. The main blade further crushes larger particles, thus ensuring smooth grinding. The female die head and the guide ring 8 are integrated. The guide ring 8 is provided with a flange that connects to the flange of the mixing cylinder 2. The cover is stacked on top of the other two parts, and the three are connected by flanges.

[0030] The grinding assembly 3, the airflow disturbance assembly 4, the powder mixing device 5, the heating sleeve 6, the quantitative feeding crushing assembly 7, the temperature sensor 10, the air pressure sensor 11, and the electric valve 13 are all connected to the control cabinet 14 via communication or electrical connection. The first drive motor 31, the second drive motor 51, and the third drive motor 72 are all servo motors.

[0031] The parts and equipment all use conventional models in the prior art. In addition, the circuit connections and communication connections use conventional connection methods in the prior art, which are not the innovations of this application. For example, the communication and electrical connections between the control cabinet 14 and various components will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] Working principle: The staff adds feed additives to the electronic weighing pan 73 until the appropriate amount is reached. The control cabinet 14 then controls the third drive motor 72 to rotate the electronic weighing pan 73, which pours the feed additives into the crushing roller 74. The two crushing rollers 74 rotate inward relative to each other for initial crushing. After initial crushing, the material enters the grinding component 3 for grinding. The ground material forms a circulating flow under the action of the airflow disturbance component 4. The air pressure sensor 11 monitors the air pressure inside the cylinder in real time. At the same time, the mixing device 5 thoroughly stirs and mixes it; When heating is required, the power supply to the heating plate is turned on, and the heating plate begins to generate heat. The heat is transferred to the outer wall of the mixing drum 2 through heat conduction, thereby heating the powder mixing area inside the mixing drum 2. The temperature controller monitors the temperature inside the mixing drum 2 in real time. When the temperature is higher than the set value, the power of the heating plate is reduced or the power supply is cut off to stop heating. During discharge, the airflow disturbance component 4 is stopped, the electric valve 13 is opened, and the powder flows out from the discharge port 12. At this time, the scraper 54 of the powder mixing device 5 quickly pushes the powder in the feeding area to the discharge ports 12 on both sides, so as to achieve smooth discharge of the powder.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
