Description

Technical Field

[0001] The utility model relates to the technical field of clinker calcining, in particular to a clinker calcining combustion-supporting mechanism. Background Art

[0002] Cement clinker is a semi-finished product obtained by mixing limestone, clay and iron raw materials in appropriate proportions, burning them until they are partially or completely melted, and cooling them. In the cement industry, the most commonly used silicate cement clinker has the main chemical components of calcium oxide, silicon dioxide and a small amount of aluminum oxide and iron oxide. The main mineral components are tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium aluminoferrite.

[0003] When clinker is calcined, a fan is used to transport air into the cement kiln. Impurities in the air will affect the effect of clinker calcination, and the air temperature will be affected by the ambient temperature. When the ambient temperature is low, the air temperature is also relatively low. After the lower temperature air enters the furnace, it will lower the internal temperature, thereby affecting the clinker calcination. Therefore, the utility model provides a clinker calcination combustion-aiding mechanism. Utility Model Content

[0004] The purpose of the utility model is to provide a clinker calcining combustion-supporting mechanism, which can filter impurities in the air and heat the air to prevent cold air from affecting the clinker calcining, thereby ensuring the advantages of the clinker calcining effect and solving the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clinker calcining combustion-supporting mechanism, comprising a bellows, a filter box and a conveying pipe, a driving device is arranged in the bellows, a fan blade is installed at the end of the main shaft of the driving device, a connecting pipe is installed at the side end of the bellows, the filter box is installed at the end of the connecting pipe, the filter box is made of metal, and a symmetrically distributed mounting opening is arranged at the upper end of the filter box, a filter screen is installed from the mounting opening into the filter box, the filter screen comprises a frame, a closed cover plate is arranged at the upper end of the frame, an ash box is installed at the lower end of the filter box, the ash box is connected with the filter box, the conveying pipe is installed at the side end of the filter box, the conveying pipe is connected with the filter box, an electromagnetic regulating valve is arranged on the conveying pipe, and heating pipes distributed equidistantly are arranged on the outer surface of the conveying pipe.

[0006] When using the clinker calcining combustion-supporting mechanism of the utility model,

[0007] The fan blades can be driven to rotate at high speed, and the high-speed rotation of the fan blades can allow external air to enter the bellows, and the air can be transported at the same time. The transported air can enter the filter box, and the air can be filtered through two filters. The impurities and dust trapped by the filters can be collected through the ash box. When the filter needs to be cleaned, the equipment stops working, and the filter can be easily removed from the filter box by manually pulling the handle upwards, so that the filter can be cleaned. The filtered air can enter the delivery pipe. When the external ambient temperature is low, the air transported in the delivery pipe can be heated by the heating pipe, and the air can be transported to the cement kiln through the delivery pipe for clinker calcination and combustion assistance. The input air volume can be adjusted by the electromagnetic regulating valve.

[0008] Preferably, an air inlet is provided at the front end of the bellows, and there are four air inlets in total, and the four air inlets are distributed in an array with respect to the bellows.

[0009] Preferably, a handle is installed on the upper end of the sealed cover.

[0015] 1. When clinker is calcined to assist combustion, the input air can be filtered through a filter, which can filter and intercept impurities and dust in the air. Air that removes impurities and dust can better ensure the effect of clinker calcination.

[0016] 2. When the external ambient temperature is low, the air transported in the conveying pipe can be heated through the heating pipe, and the air can be transported to the cement kiln through the conveying pipe for clinker calcination and combustion. The air can be heated to prevent the cold air from affecting the clinker calcination and ensure the clinker calcination effect. BRIEF DESCRIPTION OF THE DRAWINGS
