Description

Technical Field

[0001] The utility model belongs to the technical field of hopper equipment, and in particular relates to a hopper with a new structure. Background Art

[0002] In the cement production process, bucket elevators are often used to achieve continuous transportation of materials from low to high places. However, in the process of material transportation and transfer, the materials are often affected by the characteristics of the materials. Wet and high-water materials will stick to the bucket, causing the bucket capacity to decrease, the load to increase, and the waste to increase. Especially in the batching process of cement raw materials, since gypsum and various waste-utilized mixed materials need to be added, this mixed material often has a certain amount of moisture. When it meets cement clinker, it is often easy to stick, which will cause the equipment's lifting capacity to decrease at the least, and cause serious damage to the lifting equipment at the worst, and affect the transportation efficiency of the bucket.

[0003] In order to solve the deficiencies of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a viscous material lifting bucket for an elevator [201820254986.9], which includes a bucket body with an upper opening, a rotating pin for rotationally connecting with the lifting chain on the elevator, a high-position L-shaped baffle and a low-position L-shaped baffle are respectively arranged at different positions and heights on one side of the bucket body, and the lower part of the bucket body has a number of gaps to form a hollow structure. A lining cloth is laid inside the bucket body, and the upper edge of the lining cloth is fixed to the inner wall of the bucket body by a clamp and bolts. The rest of the lining cloth is surrounded by the same shape as the inner structure of the bucket body and is attached to the inner wall of the lower part of the bucket body, so that when it is turned over to discharge, it can be turned out of the bucket body under the sticky effect of the sticky material.

[0004] The above scheme solves the problem of easy sticking of materials in the existing hopper to a certain extent, but the scheme still has many shortcomings. For example, the hopper is used on a Z-type elevator, wherein the transportation speed of the Z-type elevator is not high and the loading capacity of the hopper is not high; the structural strength of the lining cloth is not high and is only suitable for hoppers with low load capacity. When the lining cloth is used in a hopper with high load capacity, it is easy to be damaged under long-term use, and its service life is short, which affects the transportation efficiency.
