Description

Technical Field

[0001] This utility model relates to the field of kiln combustion aid technology, specifically a kiln combustion aid device. Background Technology

[0002] A kiln is a high-temperature device used for heating and melting materials, and it is widely used in various industrial fields such as ceramics, glass, metals, cement, and refractory materials. The design and construction of kilns vary depending on the type of materials to be processed, the process requirements, and the production scale.

[0003] In the operation of a kiln, the coal powder added to the kiln is relatively concentrated, and the high moisture content of the coal powder can easily lead to incomplete combustion of the coal powder fuel in the kiln. This not only wastes the coal powder fuel, but also fails to guarantee the temperature inside the kiln, affecting the firing process. Therefore, this utility model proposes a kiln combustion aid device. Utility Model Content

[0004] The purpose of this utility model is to provide a kiln combustion aid device that can heat pulverized coal and air and uniformly add pulverized coal into the kiln so that the pulverized coal can be fully burned. This not only saves fuel but also ensures the normal operation of the kiln, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a kiln combustion aid device, comprising a pulverized coal box, a feeding pipe, and a blower box. A feed inlet is provided on one side of the upper end face of the pulverized coal box. A heating box arranged in a ring is installed on the inner wall of the pulverized coal box, and an array of electric heating tubes is installed inside the heating box. A first rotating shaft is rotatably installed on the upper inner wall of the pulverized coal box, and a stirring rod is installed on the first rotating shaft. The feeding pipe is installed at the lower end of the pulverized coal box and is connected to the pulverized coal box. A second rotating shaft is rotatably installed inside the feeding pipe, and an array of feeding plates is installed on the second rotating shaft. A feeding pipe is installed at the lower end of the feeding pipe and is connected to the feeding pipe. An annular pipe is connected to the end of the feeding pipe, and an array of discharge pipes is provided on the inner wall of the annular pipe.

[0006] When using the kiln combustion aid device of this utility model...

[0007] The annular pipe is installed inside the kiln, and the feeding pipe is embedded from the outside of the kiln and connected to the annular pipe. Coal powder fuel is added into the coal powder box. The coal powder fuel can be heated by the operation of the electric heating tube. The operation of the first drive device causes the first rotating shaft to rotate, and the coal powder can be stirred by the stirring rod to ensure that it is fully heated, thereby drying the coal powder and removing moisture. After the coal powder is dried, the operation of the second drive device causes the second rotating shaft to rotate, and the coal powder can be fed into the feeding pipe by the feeding plate. The operation of the third drive device causes the impeller to rotate at high speed. The high speed of the impeller can blow air. The operation of the electric heating wire can heat the air. The hot air enters the feeding pipe and transports the coal powder into the annular pipe, so that the coal powder is sprayed out from the discharge pipe into the kiln for combustion.

[0008] Preferably, the upper end face of the pulverized coal box is provided with an exhaust hole that communicates with the pulverized coal box.

[0009] Preferably, a first driving device is installed at the upper end of the pulverized coal box, and the main shaft of the first driving device is connected to the axis of the first rotating shaft. The operation of the first driving device can cause the first rotating shaft to rotate.

[0010] Preferably, a second drive device is installed on the side end of the feed pipe, and the main shaft of the second drive device is connected to the axis of the second rotating shaft. The operation of the second drive device can cause the second rotating shaft to rotate.

[0011] Preferably, an equipment cavity is formed between the heating box and the inner wall of the pulverized coal box, and the electric heating tube is located inside the equipment cavity.

[0012] Preferably, the bellows is installed at the beginning of the feeding pipe and is connected to the feeding pipe. The front end of the bellows has an array of air inlets. As the impeller rotates at high speed, external air can enter the bellows through the air inlets.

[0013] Preferably, a third driving device is installed inside the air box. An impeller is installed at the end of the main shaft of the third driving device, and an electric heating wire is installed inside the air box, located on one side of the impeller. The operation of the third driving device can cause the impeller to rotate at high speed to blow air, and the operation of the electric heating wire can heat the air to form hot air.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When pulverized coal is added to the pulverized coal box, the pulverized coal can be stirred and heated inside the pulverized coal box, so that the pulverized coal is dried and the moisture is removed. When feeding the pulverized coal, it is transported by hot air, which can prevent the low temperature of the outside air from affecting the heat inside the kiln. When the pulverized coal is transported, the pulverized coal can be evenly distributed in the kiln with the cooperation of the annular pipe and the discharge pipe. By heating the pulverized coal and air and adding the pulverized coal evenly into the kiln, the pulverized coal can be fully burned, which not only saves fuel, but also ensures the normal operation of the kiln.
