Description

Technical Field

[0001] This utility model belongs to the field of pig feed technology, specifically relating to a pig feed pellet refining equipment. Background Technology

[0002] Currently, the livestock industry commonly uses pellet processing equipment to feed livestock, such as pig feed pellets. Pig feed pellet processing equipment is an important piece of equipment for producing pig feed. It is a feed processing machine that directly compresses crushed materials such as corn, soybean meal, straw, grass, and rice husks into pellets.

[0003] Currently, Chinese Patent Publication No. CN215087722U discloses a pig feed pellet refining equipment, including a processing box with a second discharge port on one outer surface and a second elevator below the discharge port; and a screening mechanism installed inside the processing box. This pig feed pellet refining equipment, through its screening mechanism, can quickly screen the pig feed pellets, further crushing larger pellets, thereby improving the pass rate and reducing economic losses. Furthermore, the guide rod and rotating seat allow the screening plate to move up and down, preventing clogging and reducing maintenance frequency. The entire device has a simple structure, is easy to operate, and enhances the overall practicality of the device.

[0004] Although the aforementioned pig feed pellet refining equipment can solve the corresponding technical problems, in actual use, a single screening plate is difficult to effectively ensure the uniformity of pellet size. Furthermore, if the raw materials are not fully mixed when entering the pellet mill, it will lead to uneven distribution of pellet components, resulting in inconsistent pellet size. In addition, when the feed amount is too large, the pellet mill may not be able to fully process the raw materials, which will also affect the uniformity of the pellets. Such uneven pellets may have an adverse effect on pigs' feed intake and digestion, reducing feed utilization efficiency. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a pig feed pellet refining equipment to solve the technical defects mentioned above, which are that a single screening plate cannot effectively ensure uniform pellet size during use, and may result in incomplete screening or slow screening speed, thus affecting the overall processing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pig feed pellet refining equipment, comprising a frame, a hollow hole in the center of the upper surface of the frame, a pig feed raw material premixing tank on the upper surface of the hollow hole, a feeding pipe connected to the lower surface of the pig feed raw material premixing tank, the feeding pipe being located inside the hollow hole, two sets of feeding hoppers connected to the upper surface of the pig feed raw material premixing tank, and a pellet mill correspondingly provided at the lower end of the feeding pipe.

[0007] As a further embodiment of this utility model, the pig feed raw material premixing tank is equipped with a stirring rod inside, a drive motor is provided between the two sets of feeding hoppers, a through hole is provided on the upper surface of the frame, and the output shaft of the drive motor is connected to one end of the upper surface of the stirring rod through the through hole. The stirring rod is spiral in shape.

[0008] As a further preferred embodiment of this utility model, a second through hole is provided on one side of the pig feed raw material premixing tank, and a fan is installed in the second through hole. The fan is inclined, and a ventilation pipe is connected to the other side of the pig feed raw material premixing tank.

[0009] As a preferred embodiment of this utility model, a rotary valve is installed in the middle section of the feeding pipe, and the rotary valve is used to control the feeding amount.

[0010] As a further embodiment of this utility model, the lower end of the granulator is provided with a screening frame, and two sets of rods are fixedly installed inside the screening frame, wherein the spacing between the two sets of rods is distributed differently.

[0011] As a further embodiment of this utility model, the screening frame is provided with two sets of discharge holes on one side, and the two sets of discharge holes are respectively opposite to one end of the discharge rod. A discharge plate is provided on one side of the discharge hole, and the discharge plate has a certain degree of inclination.

[0012] Compared with existing technologies, the pig feed pellet refining equipment provided by this utility model has the following beneficial effects:

[0013] 1. Through the design of the pig feed raw material premixing tank and feeding hopper, the raw materials to be processed are poured into the feeding hopper. Different raw material components can be added to the two feeding hoppers respectively, which makes it easy to control the proportion of raw materials. Then, the stirring rod rotates and stirs, so that the different raw materials are fully contacted and mixed in the pig feed raw material premixing tank, ensuring that the raw material components are evenly distributed. This is beneficial to the uniformity of the particle components in the subsequent pelleting process, thereby reducing the particle size difference caused by uneven components and ensuring the uniformity of particle size.

[0014] 2. Through the design of the fan and rotary valve, the fan is installed at an angle and works with the ventilation pipe during the mixing process. This allows air to circulate in the premix tank of pig feed ingredients. The airflow can remove some moisture, thus achieving a certain dehumidification effect and preventing the raw materials from accumulating in the pellet mill due to excessive humidity. By adjusting the speed of the rotary valve during feeding, the flow rate of raw materials from the premix tank into the pellet mill can be regulated, avoiding excessive feeding at one time. This prevents uneven distribution of raw materials inside the pellet mill, which can lead to different compression and friction forces and result in uneven pellet size.

[0015] 3. Through the design of the sieve frame and the bar rack, if factors affect the mixing process and cause the raw materials to not be fully mixed, it may lead to uneven particle size. The two sets of bar racks with different spacing can further ensure the particle size, so that the produced particles can be collected in different sizes, avoiding the mixing of excessively large or small particles together, and making it easy to distinguish them for subsequent work.

[0025] See appendix Figure 1 - Appendix Figure 3 As shown, this embodiment provides a pig feed pellet refining equipment, including a frame 1. A hollow hole is provided in the center of the upper surface of the frame 1. A pig feed raw material premixing tank 2 is located on the upper surface of the hollow hole. A feeding pipe 25 is connected to the lower surface of the pig feed raw material premixing tank 2, and the feeding pipe 25 is located within the hollow hole. Two sets of feeding hoppers 23 are connected and installed on the upper surface of the pig feed raw material premixing tank 2. A pellet mill 3 is correspondingly located at the lower end of the feeding pipe 25. A stirring rod 27 is provided inside the pig feed raw material premixing tank 2. A drive motor 24 is located between the two sets of feeding hoppers 23. A through hole is provided on the upper surface of the frame 1, and the output shaft of the drive motor 24 is connected to one end of the upper surface of the stirring rod 27 through the through hole. The stirring rod 27 is spiral-shaped.

[0026] The design of the pig feed raw material premixing tank 2 and the feeding hopper 23 allows for the addition of different raw material components to the two feeding hoppers 23, facilitating the control of the raw material ratio. The stirring rod 27 then rotates and stirs the different raw materials to ensure that they are fully in contact and mixed in the pig feed raw material premixing tank 2, ensuring that the raw material components are evenly distributed. This is beneficial to the uniformity of the particle components during the subsequent pelleting process, thereby reducing the particle size difference caused by uneven components and ensuring the uniformity of particle size.

[0027] See appendix Figure 2 As shown, a second through hole is provided on one side of the pig feed raw material premixing tank 2, and a fan 22 is installed in the second through hole. The fan 22 is inclined. A ventilation pipe 21 is connected to the other side of the pig feed raw material premixing tank 2. A rotary valve 26 is installed in the middle section of the feed pipe 25. The rotary valve 26 is used to control the feed amount.

[0028] The design of the fan 22 and rotary valve 26 allows for airflow within the premixed pig feed material tank 2 when the mixing rod 27 is stirring. The fan 22 is installed at an angle and works in conjunction with the ventilation pipe 21. This airflow removes some moisture, thus achieving a dehumidification effect and preventing the raw materials from accumulating in the pellet mill 3 due to excessive humidity. By adjusting the rotation speed of the rotary valve 26 during feeding, the flow rate of raw materials from the premixed pig feed material tank 2 into the pellet mill 3 can be regulated, preventing excessive feeding at once. This avoids uneven distribution of raw materials inside the pellet mill 3, resulting in different extrusion and friction forces and uneven pellet size.

[0029] The rotary valve 26 has its own motor drive, which is a mature technology and will not be elaborated on here. The motor of the rotary valve 26 can be connected to an external controller via a wire.

[0030] See appendix Figure 3 As shown, the lower end of the granulator 3 is provided with a screening frame 4. Two sets of vertically arranged rods 42 are fixedly installed inside the screening frame 4. The spacing between the two sets of rods 42 is different. Preferably, the spacing between the upper rods 42 is greater than the spacing between the lower rods 42. Two sets of discharge holes 43 are provided on one side of the screening frame 4, and the two sets of discharge holes 43 are corresponding to one end of the rods 42. A discharge plate 41 is provided on one side of the discharge hole 43. The discharge plate 41 has a certain inclination.

[0031] The design of the sieve frame 4 and the rack 42 ensures that if the raw materials are not fully mixed due to factors during the stirring process, the particle size may be uneven. The rack 42 with two sets of different spacings can further ensure the particle size, so that the produced particles can be collected in different sizes, avoiding the mixing of excessively large or small particles, and making it easier to distinguish them for subsequent work.

[0032] Working principle: The raw materials to be processed are poured into the feed hopper 23 to add various pig feed raw materials into the pig feed raw material premix tank 2. Then, the stirring rod 27 is rotated and stirred. When the stirring rod 27 is stirring, the fan 22 is installed at an angle and cooperates with the ventilation pipe 21 to make the air in the pig feed raw material premix tank 2 flow. The air flow can remove some moisture, thus achieving a certain dehumidification effect. When feeding, the flow rate of raw materials from the pig feed raw material premix tank 2 into the pellet mill 3 is adjusted by adjusting the speed of the rotary valve 26. Then, the raw materials enter the pellet mill 3 for processing.

[0033] The above description illustrates the basic principles of the present invention. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The above embodiments and descriptions in the specification are only for illustrating the principles of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
