A feeding device for a gypsum calcination kiln

Abstract

This utility model discloses a feeding device for a gypsum calcination kiln, relating to the field of gypsum calcination feeding technology. It includes a fixed frame, a screening device fixedly installed on the top of the fixed frame, a crushing device fixedly installed on the side of the screening device, and a swinging feeding device fixedly installed inside the fixed frame. This gypsum calcination kiln feeding device uses a conveying auger to transport gypsum raw materials into the interior of a filter ring. A crushing paddle stirs the gypsum raw materials inside the filter ring and crushes any clumps, preventing clumping and ensuring proper feeding. A swinging motor controls the rotation of a rotating ring, causing a fixed column to move a rotating ball. A connecting rod pulls a movable frame to rotate around a limiting rod, causing the rotating rod to reciprocate inside the bottom frame. This, in turn, causes the feeding nozzle to swing left and right, resulting in more even distribution of the raw materials and improving the uniformity of gypsum feeding.

Description

Technical Field

[0001] This utility model relates to the field of gypsum calcination feeding technology, and more specifically, to a gypsum calcination kiln feeding device. Background Technology

[0002] Gypsum, as an important non-metallic mineral resource, has wide and irreplaceable applications in various fields such as construction, building materials, chemicals, and agriculture. In the deep processing of gypsum, calcination is one of the core technological steps. Its purpose is to remove the water of crystallization from natural gypsum or industrial by-product gypsum by heating it, thus producing hemihydrate or anhydrous gypsum products with cementing properties. The gypsum calcination kiln, as a key piece of equipment in realizing this process, is closely related to the performance of the feeding device in terms of its operational stability, heat exchange efficiency, and final product quality. The rationality of the feeding device directly determines the uniformity of gypsum raw material distribution and residence time within the kiln, as well as the continuity of the calcination process, and is a prerequisite for ensuring the efficient operation of the entire gypsum calcination production line.

[0003] Currently, the common gypsum calcination kiln feeding devices on the market are mainly divided into several types, including screw conveyor feeding, bucket elevator feeding, and chute feeding. However, traditional feeding devices generally suffer from the problem of gypsum raw materials easily arching and clogging during the feeding process. Once clogging occurs, not only does it require machine shutdown for manual cleaning, which seriously affects production continuity and causes a lot of time and manpower waste, but existing feeding devices also cannot achieve uniform distribution of gypsum raw materials at the kiln inlet, resulting in uneven distribution of raw materials in the kiln. This not only reduces the product qualification rate but also increases energy consumption and production costs. Utility Model Content

[0004] The main purpose of this utility model is to provide a feeding device for gypsum calcination kilns, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A gypsum calcination kiln feeding device includes a fixed frame, a screening device fixedly installed on the top of the fixed frame, a crushing device fixedly installed on the side of the screening device, and a swing feeding device fixedly installed inside the fixed frame. The oscillating feeding device includes a rotating ring and a rotating rod. A rotating base is fixedly installed on the top of the rotating rod, and a feeding nozzle is fixedly connected to the lower end of the rotating base.

[0010] Preferably, the feeding motor is fixedly installed on the right side of the conveying pipe, the conveying auger is rotatably installed inside the conveying pipe, and the crushing paddle is rotatably installed on the inner wall of the filter ring.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The feeding motor controls the rotation of the rotating shaft, which conveys the gypsum raw material into the filter ring screen through the conveying auger. At the same time, the rotating shaft drives the crushing paddle to rotate, so that the crushing paddle stirs inside the filter ring screen and crushes the clumps of gypsum raw material, so as to avoid the gypsum raw material clumping, which would affect the feeding of gypsum raw material. 2.

A connecting rod 29 is fixedly connected to the side of the movable frame 28. A rotating ball 210 is fixedly connected to the end of the connecting rod 29 away from the movable frame 28.

[0016] like Figure 4 As shown, the fixed frame 1 includes a support frame 11, a side frame 13 is fixedly connected to the right side of the support frame 11, and a bottom frame 12 is fixedly connected to the lower left end of the support frame 11.

[0017] Among them, a swing motor 21 is fixedly connected to the right side of the side frame 13, the output end of the swing motor 21 is fixedly connected to the right side of the rotating ring 22, the rotating ring 22 is rotatably installed on the left side of the side frame 13, a fixed column 23 is fixedly installed on the upper end of the left side of the rotating ring 22, a rotating ball 210 is rotatably installed inside the fixed column 23, and a rotating rod 24 is rotatably installed inside the bottom frame 12.

[0018] Specifically, the swing motor 21 controls the rotating ring 22 to rotate, causing the fixed column 23 to drive the rotating ball 210 to move. The rotating ball 210 rotates inside the fixed column 23 and pulls one end of the connecting rod 29 to rotate around the side of the rotating ring 22 through the fixed column 23. At this time, the connecting rod 29 pulls the movable frame 28 to rotate around the limit rod 27, causing the rotating rod 24 to rotate back and forth inside the bottom frame 12, thereby causing the feeding nozzle 26 to swing left and right, making the raw material feeding and laying more even, and improving the uniformity of gypsum raw material feeding.

[0019] like Figure 3 As shown, the screening device 3 includes a fixed box 31 and a filter ring 33. The bottom of the fixed box 31 is fixedly connected to a discharge nozzle 32.

At the same time, the rotating shaft 42 drives the crushing paddle 44 to rotate, so that the crushing paddle 44 stirs inside the filter ring 33 and crushes the clumped gypsum raw material through the crushing paddle 44, so as to avoid the gypsum raw material from clumping and affecting the feeding of gypsum raw material.

[0023] The working process of this utility model is as follows: In use, gypsum raw materials are fed into the inside of conveying pipe 34 through feeding hopper 35. At this time, feeding motor 41 controls rotating shaft 42 to rotate, and conveying auger 43 to rotate, conveying gypsum raw materials into the inside of filter ring screen 33. At this time, rotating shaft 42 drives crushing paddle 44 to rotate, so that crushing paddle 44 stirs inside filter ring screen 33 and crushes the clumped gypsum raw materials. The crushed gypsum raw materials are screened through filter ring screen 33 and discharged into the inside of rotating base 25 through discharge nozzle 32. The swing motor 21 controls the rotating ring 22 to rotate, causing the fixed column 23 to drive the rotating ball 210 to move.

At this time, the connecting rod 29 pulls the movable frame 28 to rotate around the limit rod 27, causing the rotating rod 24 to rotate back and forth inside the bottom frame 12, thereby causing the feeding nozzle 26 to swing left and right, making the raw material feeding and laying more even.
