Description

Technical Field

[0001] This utility model relates to the field of feed ingredient feeding, specifically to a feed trace element feeding device. Background Technology

[0002] In the feed production process, the addition of trace elements is a crucial step in ensuring a balanced diet. Currently, the industry commonly uses manual methods to add trace elements to feed silos containing main raw materials such as corn and soybean meal.

[0003] Since the amount of trace elements added is typically only 0.5%-2% of the total feed, this manual handling method has significant drawbacks: First, workers need to frequently travel back and forth to the top of the silo to add the feed, which is not only labor-intensive and inefficient, but also carries the risk of falls while working at heights. Second, manual operation makes it difficult to ensure the precise addition of trace elements, easily leading to uneven mixing or inaccurate dosage. Third, the open manual feeding method easily causes dust to fly, resulting in both raw material waste and pollution of the working environment. In addition, when multiple trace elements need to be added simultaneously, existing methods cannot achieve the sequential addition of different trace elements, easily leading to cross-contamination of different components during transportation. These problems severely restrict the automation level of feed production and the stability of product quality. Utility Model Content

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0017] like Figure 1-2 As shown, this application proposes a feed trace element feeding device, including a feed hopper for holding trace elements, a material conveying fan inside the feed hopper, an adsorption tube extending into the feed hopper connected to the inlet of the material conveying fan, a delayed feeding device provided on the outside of the adsorption tube, and the outlet of the adsorption tube connected to the upper part of the feed hopper through a conveying pipe.

[0018] The material hopper can be made of stainless steel, with a capacity of 50-200 liters depending on actual needs. A centrifugal fan can be used for material conveying, with a recommended airflow range of 5-15 cubic meters per minute. The adsorption pipe diameter is preferably 50-100 mm, and the material can be PVC or stainless steel. The delayed feeding device can be mechanical, including but not limited to baffle structures. The conveying pipe can be connected using a flexible hose, with the length determined based on the actual installation distance.

[0019] This technical solution uses negative pressure generated by a material conveying fan to draw trace elements from the material container, which are then transported to the silo via adsorption and conveying pipes. A delayed feeding device controls the feeding speed of the trace elements, preventing over-feeding. Compared to manual handling, this device achieves automated conveying of trace elements, reducing labor intensity and safety risks, and improving feeding efficiency and accuracy. In practical implementation, the fan parameters and the structural parameters of the delayed feeding device can be adjusted according to the characteristics of different trace elements.

[0020] Furthermore, this application also proposes that the delayed feeding device includes a conical baffle plate fixed to the outside of the adsorption tube, the conical baffle plate having multiple triangular seepage holes, and multiple adsorption holes being opened at the conical baffle plate directly opposite the adsorption tube.

[0021] The conical baffle can be made of stainless steel or engineering plastic, with a preferred taper angle of 30-60 degrees to prevent direct contact between the material and the adsorption tube. The triangular structure of the seepage holes can be designed as equilateral or right triangles, with side lengths controlled between 3-8 mm. The diameter of the adsorption holes is typically 1 / 3 to 1 / 2 of the side length of the seepage holes, evenly distributed vertically. In practical applications, the conical baffle can be welded to the outer wall of the adsorption tube.

[0022] Specifically, this technical solution achieves precise control and conveying of trace materials through the combination of a conical baffle and a special perforation structure. The conical structure guides the material towards the seepage holes, while the triangular hole design effectively prevents blockage. Furthermore, by strategically positioning the adsorption holes and seepage holes, the material flows in an orderly manner under negative pressure. Compared to traditional straight-through feeding methods, this structure significantly improves the uniformity and metering accuracy of trace component addition, avoiding the inefficiencies and safety risks associated with manual handling. During conveying, the material is initially dispersed through the seepage holes and then stably drawn into the conveying system through the adsorption holes. This staged feeding mechanism is particularly suitable for conveying powdered trace elements with poor flowability.

[0023] Furthermore, this application also proposes that the seepage holes are spaced apart in the center of the adsorption holes.

[0024] Specifically, the seepage holes are triangular openings, evenly distributed along the longitudinal direction of the conical baffle, with a fixed spacing between adjacent seepage holes. The adsorption holes are circular through holes, arranged in an alternating pattern with the seepage holes.

[0025] This technical solution optimizes the spatial layout of the seepage holes and adsorption holes, enabling the material to form a stable airflow channel during negative pressure adsorption. Specifically, when the material conveying fan is operating, the negative pressure airflow generated by the adsorption holes and the material flow formed by the seepage holes complement each other. The seepage holes primarily control the continuous supply of material, while the adsorption holes are responsible for the rapid conveying of material. This structural design effectively solves the problems of material blockage and uneven conveying in traditional feeding devices, achieving efficient and stable delivery of trace elements. Furthermore, the special structure of the triangular seepage holes prevents material accumulation within the channels, ensuring long-term reliability.

[0026] Furthermore, this application also proposes that a hopper be provided at the top of the material barrel.

[0027] The hopper, serving as a feeding device, can adopt a conical structure and is preferably made of stainless steel. The bottom of the hopper and the top of the hopper can be fixed together by welding. This technical solution achieves convenient addition of trace elements by placing the hopper at the top of the hopper. The hopper also serves as a transition container, avoiding the inconvenience of manually adding materials directly into the hopper. Therefore, operators can complete the feeding operation at the hopper without climbing to the top of the hopper, significantly reducing labor intensity and safety hazards.

[0028] Furthermore, this application also proposes that the material conveying blower is provided with a closed shell on the outside, and the drive motor of the material conveying blower is located on the top of the closed shell and outside the hopper.

[0029] The enclosed housing can be made of metal sheet, specifically stainless steel sheet welded together. Shock-absorbing pads can be installed inside the housing to reduce vibration transmission during fan operation. The motor is fixed to the top of the housing, maintaining a safe distance from the hopper to avoid material contamination.

[0030] Therefore, this technical solution effectively solves the problems of contamination and malfunction caused by the motor coming into contact with materials by placing the drive motor externally and installing a closed housing. Specifically, the closed housing isolates material dust from entering the blower, while the external motor design facilitates maintenance and repair and avoids the impact of high-temperature environments on motor lifespan. Compared to existing technologies where the motor is directly exposed to the material environment, this design significantly improves equipment reliability and service life while reducing maintenance costs. This structure is particularly suitable for industrial scenarios with high dust levels, such as feed production.

[0031] The implementation principle of a feed trace element feeding device according to an embodiment of this application is as follows:

[0032] When feeding trace elements into silo 10, the drive motor 4 can be turned on. The drive motor 4 drives the blades of the material conveying fan 3 to rotate, conveying the feed trace elements (such as copper sulfate, ferrous sulfate, zinc oxide, manganese, selenium, etc.) in powder or small particle form along the conveying pipe 9. Figure 3 (as shown);

[0033] The conical baffle 7 with its conical structure guides the material to concentrate in the seepage holes 8. The triangular hole design effectively prevents material blockage. Simultaneously, by setting the positional relationship between the adsorption holes 6 and the seepage holes 8, the material flows in an orderly manner under negative pressure. When passing through the centrifugal fan, the material comes into contact with the high-speed rotating blades (typically 1000-3000 r / min). To ensure the blades' lifespan, high-manganese steel (Mn13) blades can be selected for conventional feed trace elements, as they offer a balance of hardness and toughness.
