Abstract
Description
Technical Field
[0001] This utility model belongs to the field of feed processing technology, and specifically relates to a mixing device for preparing low-phosphorus raw materials. Background Technology
[0002] Low-phosphorus feed refers to feed with a phosphorus content lower than conventional levels. It is mainly used to control phosphorus intake and has certain applications in livestock and poultry farming, aquaculture, and other fields. Currently, the production process of low-phosphorus feed is as follows: 1. Raw material processing: Weigh raw materials such as corn flour, soybean meal, wheat flour, fish meal, and protein powder according to the formula ratio, and screen and clean them to ensure the quality of the raw materials; 2. Ingredient mixing: Put the processed raw materials into a mixer, add phosphorus regulators such as calcium dihydrogen phosphate and calcium carbonate, as well as mineral and vitamin additives, and mix thoroughly to ensure that the various raw materials are evenly distributed; 3. Humidification: Add an appropriate amount of water to the mixed ingredients for humidification treatment, so that the moisture content of the ingredients reaches about 7%; 4. Forming: Send the humidified ingredients into a pellet mill, where they are extruded and cut to form... 5. Drying: The formed feed pellets are fed into a dryer, where hot air evaporates the moisture in the feed to achieve the appropriate moisture content; 6. Packaging: The dried feed pellets are packaged for storage and transportation; 7. Additive treatment: Yeast, probiotics, antibiotics, and other additives are added to the feed according to the formula ratio and mixed thoroughly; 8. Quality inspection: The finished feed is inspected for quality, including testing for appearance, pellet hardness, moisture content, and other indicators to ensure that the feed meets the standards; 9. Storage and sales: The quality-inspected feed is stored and sold as needed.
[0003] However, when mixing low-phosphorus raw materials, existing mixing devices generally use a single stirring method, which cannot fully disperse the raw materials, resulting in some raw materials clumping and affecting the mixing effect. At the same time, due to the small amount of phosphorus regulators and additives added, they are not easy to mix evenly with other raw materials, affecting product quality.
[0004] Therefore, there is an urgent need for a mixing device for preparing low-phosphorus raw materials. Utility Model Content
[0005] To address the aforementioned deficiencies in existing technologies, this utility model provides a mixing device for preparing low-phosphorus raw materials, comprising a tank, a geared motor, a main stirring shaft, two auxiliary stirring shafts, and two feeding pipes. The tank has an inlet on its side and an outlet at its bottom. The geared motor is located outside the tank. The main stirring shaft and the two auxiliary stirring shafts are vertically arranged inside the tank. The top end of the main stirring shaft extends through the tank and is connected to the output shaft of the geared motor. The main stirring shaft is sealed to the top wall of the tank and rotatably connected. Multiple inclined stirring rods are mounted on the main stirring shaft. Two auxiliary stirring shafts are located on the left and right sides of the main stirring shaft. The top ends of both auxiliary stirring shafts are rotatably connected to the top wall of the tank. The two auxiliary stirring shafts are connected to the main stirring shaft through a transmission device. Each of the two auxiliary stirring shafts is equipped with multiple crushing blades, and the multiple crushing blades and multiple stirring rods are arranged alternately without interfering with each other. Two feeding pipes are inserted horizontally into the tank from the left and right sides of the top of the tank. The ends of the feeding pipes located inside the tank are bent downwards and equipped with feeding ports. The position of the feeding pipes does not interfere with the main stirring shaft and the auxiliary stirring shafts, and does not affect the feeding of the feed inlet.
[0006] Optionally, a discharge valve is provided at the outlet of the tank.
[0007] Specifically, the discharge valve is used to control the discharge of materials.
[0008] Optionally, a baffle is provided at the top of the tank body, the baffle is located below the transmission device, and the main stirring shaft, two auxiliary stirring shafts and two feeding pipes all pass through the baffle.
[0009] Specifically, the partition is used to separate the transmission device from the material below, so as to prevent the material from affecting the transmission device.
[0010] Optionally, two arc-shaped material distribution plates are provided on the upper part of the main stirring shaft. The two material distribution plates are located on the left and right sides of the main stirring shaft and below the feeding ports of the two feeding pipes.
[0011] Specifically, the material distribution plate is used to break up the materials that are fed in, thereby improving the mixing efficiency.
[0012] Optionally, the transmission device adopts a belt pulley drive structure.
[0013] Optionally, a conveying pump is installed on the feed pipe.
[0014] Optionally, an observation window is also provided on the tank.
[0015] Specifically, the observation window allows on-site staff to observe the operation inside the tank.
[0016] This invention also includes other components that enable the mixing device for preparing low-phosphorus raw materials to function properly, all of which are conventional techniques in the art. Furthermore, any devices or components not specified in this invention employ conventional techniques in the art, such as geared motors.
[0017] The working principle of this invention is as follows: During use, the raw materials are added to the tank through the feed inlet. The geared motor is started, driving the main stirring shaft to rotate, which in turn drives the stirring rod to rotate, mixing the materials. A belt pulley transmission structure drives two auxiliary stirring shafts to rotate, which in turn drives the crushing blades. This utilizes the stirring rods to disperse the material in all directions, and the crushing blades to break up any clumps, ensuring the mixing quality and effect. Simultaneously, phosphorus regulators such as calcium dihydrogen phosphate and calcium carbonate, as well as minerals and vitamins, are fed into two feed pipes. The phosphorus regulators and additives are added to the tank through the feeding inlet and mixed with other materials under the dispersion action of the distribution plate. This simultaneous feeding and stirring improves the uniformity of the mixing of the phosphorus regulators and additives with other materials. After thorough mixing, the uniformly mixed material is discharged from the tank.
[0018] The beneficial effects of this utility model are that, through the tank, geared motor, main stirring shaft and two auxiliary stirring shafts, the material can first be diffused to the surroundings by the stirring rod, and then the pulverizing blade can be used to break up the clumps of material, ensuring the mixing quality and mixing effect of the material; at the same time, phosphorus regulator and additives are added to the tank through the feeding pipe. This simultaneous addition and stirring can improve the uniformity of the mixing of phosphorus regulator and additives with other materials, thereby improving product quality.
