Description

A conveying device for cement production Technical Field

[0001] This utility model relates to the field of cement production technology, and more specifically, to a conveying device for cement production. Background Technology

[0002] Cement, as one of the most important basic materials in the modern construction industry, has a production process that has become increasingly mature after more than two hundred years of development. The traditional cement production process mainly includes four main stages: raw material crushing, raw meal preparation, clinker calcination, and cement grinding. As a key equipment for conveying powdery and granular materials in the cement production process, screw conveyors are widely used in the horizontal or inclined conveying of raw meal, coal powder, cement products, and other materials. In the cement production process, screw conveyors need to meet special working conditions such as large conveying capacity, high sealing performance, and wear resistance.

[0003] In existing technologies, the residual heat of high-temperature clinker causes slight melting on the surface, which then adheres to other particles during the cooling process. The clinker contains a small amount of free calcium oxide, which is prone to hydration reaction and agglomeration in humid environments. This agglomeration forms bridging at the conveyor inlet, resulting in poor material discharge, increased conveying resistance, and motor overload tripping. The agglomerates rub violently against the spiral blades, accelerating blade wear. The clinker particles collide and break apart, generating a large amount of dust, which can easily spill out and affect the health of workers. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a conveying device for cement production to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a conveying device for cement production, comprising a support frame and a screw conveyor. A feed hopper is connected to one side of the screw conveyor. A rotating shaft is located at the bottom of the feed hopper. A rotating motor is located at one end of the rotating shaft, and a rotating frame is connected to the other end. A cover plate is provided on the feed hopper. One end of the cover plate is hinged to the feed hopper, and a connecting plate is located at the other end. A fixing block is provided on the feed hopper, and a fixing plate is provided on the fixing block. A connecting arm is symmetrically hinged and rotatably mounted on the fixing block. A connecting frame is hinged to the connecting arm. A connecting screw is threaded onto the connecting frame. A connecting knob is located at one end of the connecting screw, and a connecting block is located at the other end.

[0008] The present invention is further provided with a rubber pad attached to the fixing plate, which improves the tightness of the connection between the fixing plate and the connecting plate, thereby improving the stability of the cover plate fastening.

[0009] The present invention is further configured such that the rotating frame is provided with a connecting shaft, the connecting shaft is provided with a snap-fit ​​block, and the rotating shaft is provided with a snap-fit ​​groove that cooperates with the snap-fit ​​block, so as to facilitate the connection of the connecting shaft and the rotating shaft.

[0010] The present invention is further configured such that a snap-fit ​​sleeve is provided between the connecting shaft and the rotating shaft, and a connecting sleeve is provided on the snap-fit ​​sleeve. The connecting sleeve is threadedly connected to the connecting shaft. The snap-fit ​​sleeve limits the position of the snap-fit ​​block and the snap-fit ​​groove, thereby connecting and fixing the rotating frame.

[0011] The present invention is further provided that the connecting sleeve is provided with anti-slip texture to facilitate rotation of the connecting sleeve.

[0012] The present invention is further configured such that the feeding barrel is provided with a mounting bracket, the support frame is provided with a mounting groove that cooperates with the mounting bracket, and the mounting bracket and the support frame are connected by bolts. Through the cooperation of the mounting bracket and the bolts, it is convenient to install the feeding barrel on the support frame.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a conveying device for cement production, which has the following advantages:

[0017] 1. The engagement of the snap-fit ​​block and the snap-fit ​​groove facilitates the connection of the rotating shaft and the connecting shaft. The connecting sleeve drives the snap-fit ​​sleeve to fix the position of the snap-fit ​​block, thereby fixing the relative position of the rotating shaft and the connecting shaft. The rotating motor drives the rotating shaft and the rotating frame to rotate, which facilitates the mixing and crushing of the cement clinker added to the feed hopper and prevents the cement clinker from clumping and clogging the screw conveyor.

[0018] 2. When mixing cement clinker, the cover plate is placed on the feed hopper. The connecting arm and connecting frame are rotated, and the connecting screw is driven to rotate by the connecting knob. The connecting screw drives the connecting block to squeeze the connecting plate and the fixing plate, thereby fixing the cover plate on the feed hopper to prevent dust from overflowing and affecting the health of construction workers.

[0019] 3. By setting up an inspection port, it is convenient to inspect and repair the screw conveyor when it is blocked. By setting up connecting hoses and discharge pipes, it is convenient to adjust the position of the discharge pipe at the discharge end, thus improving its practicality. Attached Figure Description
