Description

Technical Field

[0001] The utility model relates to the technical field of cement processing, in particular to a screw conveying device. Background Art

[0002] A screw conveyor is a machine that uses a motor to drive the screw to rotate and push materials to achieve the purpose of transportation. It can transport horizontally, inclined or vertically and has the advantages of simple structure, small cross-sectional area, good sealing, easy operation, easy maintenance, and convenient closed transportation. Screw conveyors are divided into two types in terms of conveying form: shaft screw conveyors and shaftless screw conveyors. In terms of appearance, they are divided into U-type screw conveyors and tubular screw conveyors. For the transportation of cement, a screw conveying device is required.

[0003] For example, a Chinese patent (publication number: CN214934212U) discloses a new type of spiral conveying device for cement production, including a sealing plate and a fixed seat, a fixed seat is installed at the front end of the sealing plate, a feeding outer cylinder is arranged at the front end of the fixed seat, a spiral rod is arranged inside the feeding outer cylinder, a fixing ring is sleeved on the outer wall of the feeding outer cylinder, a support frame is arranged at the lower end of the fixing ring, and a newly added auxiliary pouring device is arranged inside the feed box when not in use, so that it will not affect the handling and use of the entire spiral conveying device for cement production when not in use. When it is needed, it only needs to pull open the auxiliary pouring device, place the bagged material on the inclined plate, and then cut the bagged material to feed. The whole process will be supported by the inclined plate, so there is no need to use manpower to carry it deliberately, which will greatly save the workers' physical strength and save time and effort.

[0004] The above-mentioned new type of spiral conveying device for cement production still has certain shortcomings. When it is needed, it is only necessary to pull open the auxiliary pouring device, place the bagged material on the inclined plate, and then cut the bagged material to feed the material. The whole process will be supported by the inclined plate, so there is no need to use manpower to carry it deliberately. In the process of transporting cement in the feeding outer cylinder, the cement needs to be sent to the measuring bucket for measurement, and the position of the feeding outer cylinder is not convenient to adjust, resulting in inconvenience for adjusting the measuring bucket at different heights. In the process of transferring cement to the weighing bucket, it is easy to cause cement to spray out, affecting the weighing. Therefore, a spiral conveying device is proposed to solve the above problems. Utility Model Content
