Description

Technical Field

[0001] The utility model relates to a drum feeder with bidirectional feeding, belonging to the technical field of mill feeding. Background Art

[0002] The mill has a wide range of applications in the mining field and is commonly used in crushing and grinding projects. The feeding and inlet methods of ore raw materials have a direct impact on the output. Conventional mill feeding mainly uses equipment such as chute pipes and feeders. The feeding principle is to rely on the initial velocity of material flow, superimpose the action of gravity, and slide down along the pipeline naturally into the grinding space. The chute pipe has low manufacturing cost, strong replaceability, and simple structure, so it has won the favor of many enterprises. Although the chute pipe feeding has certain advantages, its disadvantages are also very obvious: due to the fixed structure of the chute pipe and the material always sliding along the same path, the lower part of the chute pipe wears extremely fast, while the upper part wears less, and the wear is extremely uneven. Frequent replacement causes waste of resources; if the material continuity is poor and the flow rate is uneven, it is easy to cause blockage; common feeders include conical feeders and single-direction drum feeders. The function of the conical feeder is to buffer the impact of material falling, and the subsequent feeding still needs to be connected to the chute pipe structure, so the disadvantages of the chute pipe structure cannot be avoided; the single-direction drum feeder adopts a single spiral structure inside and can only realize one-way feeding along a fixed path during rotation, so the feeding efficiency is insufficient and the wear is relatively fast. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a drum feeder with bidirectional feeding that is not easy to block, wear-resistant and easy to disassemble and replace in view of the defects existing in the prior art.

[0004] To solve this technical problem, the utility model provides a drum feeder with bidirectional feeding, including a feeding cover and a feeding body. The feeding cover is funnel-shaped as a whole, and a partition plate is welded to the inner bottom surface thereof. Baffle plates are welded to both ends inside the feeding cover, and the baffle plates are simultaneously attached to the inner top surface and the partition plate; the feeding body is a cylindrical structure as a whole, and a double spiral guiding body is welded inside the feeding body, and the position of the double spiral guiding body corresponds to that of the partition plate; the feeding cover and the feeding body are connected together by bolts and nuts; after the material enters the feeder through the feeding cover, rapid bidirectional feeding is realized by using the internal double spiral structure and the self-rotation characteristic.

[0005] A feeding port is provided at the central funnel of the feeding cover, and the material enters through the feeding port and uniformly slides into the feeding body along the inner wall with the overall rotation.

[0006] The double spiral guiding body is composed of spiral plates, connecting plates and lip-shaped plates. The tip of the connecting plate is welded along the spiral plates, and the two spiral plates and the connecting plate are symmetrically arranged and welded to the lip-shaped plate in the middle. After the material enters the feeding body, it slides along the side surface of the spiral plate into the flange holes at the bottom of the feeding body and enters the next process.

[0007] The feed cover, baffle plate, partition plate, double - spiral material guide body and feed body are all made of processed steel plates.

[0008] Beneficial effects: In the feed link of the mill, the double - spiral diversion structure is adopted in the present utility model to achieve the function of bilateral collaborative feeding, solve the inherent defects existing in the chute feeding method, make its bilateral wear evenly, and while meeting the requirements of not being easy to block materials and being wear - resistant, it is convenient for disassembly and replacement, improve the feed efficiency of the mill, and reduce production costs.

[0022] The following describes the present utility model in detail with reference to the drawings and embodiments.

[0023] As Figures 1 - 12 shown, the utility model provides a drum feeder with double - way feeding, which includes a feeding cover 1 and a feeding body 5. The feeding cover 1 is in a funnel shape as a whole, and a partition plate 3 is welded to the inner bottom surface thereof. At both ends of the inner side of the feeding cover 1, baffle plates 2 are welded, and the baffle plates 2 are simultaneously attached to the inner top surface and the partition plate 3; the feeding body 5 is in a cylindrical structure as a whole, and a double - helix guiding body 4 is welded inside the feeding body 5, and the corresponding positions of the double - helix guiding body 4 and the partition plate 3 overlap; the feeding cover 1 and the feeding body 5 are connected together by bolts and nuts; after the material enters the feeder through the feeding cover 1, by using the internal double - helix structure and the self - rotation characteristic, rapid double - way feeding is realized, and uniform wear is achieved during operation.

[0024] A feeding port is provided at the central funnel of the feeding cover 1, and the material enters through the feeding port and uniformly slides into the feeding body 5 along the inner wall with the overall rotation.

[0025] The double - helix guiding body 4 is composed of a spiral plate 401, a connecting plate 402 and a lip - shaped plate 403. The tip of the connecting plate 402 is welded along the spiral plate 401, and the two spiral plates 401 and the connecting plate 402 are symmetrically arranged and welded to the lip - shaped plate 403 in the middle. After the material enters the feeding body 5, it slides along the side surface of the spiral plate 401 into the flange holes at the bottom of the feeding body 5 and enters the next - level process.

[0026] The feeding cover 1, the baffle plates 2, the partition plate 3, the double - helix guiding body 4 and the feeding body 5 are all made of steel plates processed.

[0027] After the assembly is completed, the material enters through the feeding port in the center of the feeding cover 1. As the feeder rotates, the material slides reversely along the inner wall of the feeding cover 1 to the feeding body 5 under the action of inertia; if some materials are highly viscous, they will rotate with the inner wall of the feeding cover 1 to the top of the feeder and fall under the action of their own weight and slide into the feeding body 5; during the feeding process, the function of the baffle plate 2 is to push and block the material, apply an external force to the material to prevent blockage; the function of the partition plate 3 is to separate the feeding body 5 from the feeding cover 1, prevent the material from entering the inner cavity of the feeding body 5, and ensure that the material flows along the designed path.

[0028] During the rotation of the feeder, the material flows into the feeding body 5 from two reserved vacancies on the feeding cover 1, thereby realizing double - way feeding. As the feeder rotates, the material slides into the inner cavity channel along two channels between the spiral plate 401 and the outer wall of the feeding body 5. The inner cavity channel is constructed by the connecting plate 402 and the lip - shaped plate 403, and the path of the channel adopts an arc transition without sharp edges to ensure the smooth sliding of the material, and finally discharges from the tail flange and enters the next - level process.

[0029] The utility model realizes the rapid and coordinated feeding at both ends of the feeder by using a double - helix diversion structure, significantly improving the feeding efficiency; the rotation during the feeding process enables the spiral diversion plate and the inner wall of the feeder to alternately friction - contact with the material, improving the wear uniformity and extending the service life; the overall structure effectively improves the feeding efficiency of the mill and reduces the spare - part replacement cost.

[0030] The above - mentioned implementation scheme of the utility model is only an example, not the only one, and all changes within the scope of the utility model or equivalent to the scope of the utility model are encompassed by the utility model.
