Description

Technical Field

[0001] The utility model relates to the technical field of double-chamber type lime shaft kilns, in particular to a double-chamber kiln top material dividing device. Background Art

[0002] The double-chamber kiln is an important industrial kiln, which is widely used in the production process of building materials such as lime and cement. In the production process of the double-chamber kiln, the kiln top material distribution device plays a vital role, and its performance directly affects the kiln's calcination effect, product quality and production energy consumption.

[0003] In the prior art, the patent with publication number CN217709263U proposes a material dividing device for the top of a double-chamber kiln. It is set on the top of the double-chamber kiln and arranged on the top frame of the kiln; a material car track is set on the top frame of the kiln for the feeding trolley to run on the material car track; a weighing buffer bin is set at the bottom of the material car track; a three-way material dividing valve is set at the bottom of the weighing buffer bin; one end of the three-way material dividing valve is connected to the weighing buffer bin to receive materials, and the other two ends are respectively connected to a kiln chamber weighing bucket through a material discharge chute to feed the materials into the kiln chamber weighing bucket, and a flap valve is set on the chute. When the weighing buffer bin is loaded with materials, the flap valve is closed. When the kiln chamber needs to be loaded with materials, the three-way material dividing valve is controlled to the position where the materials need to be loaded. After the weighing buffer bin has received the materials, the corresponding flap valve is opened to allow the materials to flow into the kiln chamber. It reduces costs and protects the environment.

[0004] As described in the above patent, when the kiln chamber needs to be loaded with materials, the material distribution is controlled by a three-way material distribution valve. However, if this type of pipeline material distribution is used, although dust can be effectively avoided, the residual material on the inner wall is difficult to clean. If an open slide is used for material distribution, dust is easily generated during the material distribution process, causing inconvenience to relevant personnel. For this reason, the utility model provides a double-chamber kiln top material distribution device. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a double-chamber kiln top material dividing device, which solves the problem that the traditional double-chamber kiln top material dividing device uses a pipeline type material dividing device. Although it can effectively avoid dust, the residual material on the inner wall is difficult to clean; if an open slide type is used for material dividing, it is easy to cause dust during the material dividing process.

[0006] To achieve the above purpose, the utility model is implemented by the following technical scheme: a double-chamber kiln top material dividing device, including a weighing bin, a material dividing mechanism is provided at the lower end of the weighing bin for dividing the materials in the weighing bin, and the material dividing mechanism includes:

[0007] The material guide assembly is arranged at the bottom of the weighing bin, and comprises semi-cylinders which are intercommunicationally installed at the bottom of the weighing bin, and both ends of the semi-cylinders are integrally formed with limiting rings, and two groups of semi-circular rings are slidably installed on one side of the semi-cylinder, and a covering film is connected between the two groups of semi-circular rings;

[0008] The positioning component is arranged on one side of the semi-cylinder and is used to limit the positions of the two groups of semi-circular rings.

[0009] Preferably, a T-shaped block is integrally formed on the side wall of the semicircular ring, and a T-shaped groove for the T-shaped block to slide with is provided on the surface of one side of the semi-cylinder.

[0010] Preferably, the positioning assembly includes a positioning block welded to one side of the semicircular ring, and there are two groups of positioning blocks. Both groups of positioning blocks are provided with an I-shaped shaft rod, and a movable connecting rod is movably connected to the I-shaped shaft rod. An I-shaped shaft rod is also provided at the end of the movable connecting rod, and a center block is movably connected to the I-shaped shaft rod.

[0011] Preferably, T-blocks are fixed to the upper and lower ends of the central block, and cross pins are inserted through the T-block and the movable connecting rod.

[0012] Preferably, support frames are welded at both ends of the weighing bin, and a material receiving seat is fixedly connected to the lower end of the support frame and is used to receive the material flowing out of the material dividing mechanism.

[0013] Preferably, a weighing bucket is provided on the upper surface of the material receiving seat, and two groups of kiln chambers are installed at the lower end of the material receiving seat, and the two groups of kiln chambers are connected to the weighing bucket up and down.

[0014] Beneficial Effects

[0015] The utility model provides a double-chamber kiln top material distribution device. Compared with the prior art, it has the following advantages:

[0016] Beneficial effects:

[0017] (1) In the double-chamber kiln top material dividing device, the material inside the weighing bin flows into the inside of the material dividing mechanism through the lower end channel, and the material enters the semi-cylinder arranged in a mirror image. At this time, the covering film is in a state of unfolding and sealing the open surface of the semi-cylinder, so that dust will not appear in the material dividing process, which effectively solves the problem that the traditional double-chamber kiln top material dividing device uses pipeline material dividing. Although it can effectively avoid dust, the residual material on the inner wall is difficult to clean. If an open slide is used for material dividing, it is easy to cause dust during the material dividing process.

[0018] (2) The top material dividing device of the double-chamber kiln is designed with a positioning component. After pulling out the T-block and the cross pin inserted through the movable connecting rod, the center block is pulled outward, so that the center block, the positioning block and the movable connecting rod are transformed from the initial straight state to a triangular state. The semicircular ring drives the covering film to shrink rapidly, thereby exposing the inner wall of the semi-cylinder, which is convenient for relevant personnel to carry out subsequent residual material cleaning work.

An I-shaped shaft rod is also provided at the end of the movable connecting rod 222, and is movably connected to a center block 223 through the I-shaped shaft rod. T-blocks 224 are fixed to the upper and lower ends of the center block 223, and cross pins 225 are inserted through the T-block 224 and the movable connecting rod 222. By manually pulling out the cross pins 225 inserted through the T-block 224 and the movable connecting rod 222, and pulling the center block 223 outward, the center block 223, the positioning block 221 and the movable connecting rod 222 are transformed from an initial straight state to a triangular state, and the semicircular ring 213 drives the covering film 215 to shrink rapidly, thereby exposing the inner wall of the semi-cylinder 211.
