Description

Technical Field

[0001] The utility model relates to the field of material guides for drying kilns, in particular to a material guide for needle coke green coke drying kilns. Background Art

[0002] The temperature in the existing coke drying kiln is relatively high. The guide needs to work in a high temperature environment and is constantly washed by coke. After working for a period of time, the guide body will be worn out, which will cause the coke to be unevenly distributed in the drying kiln and thus unevenly heated. Some coke will have high moisture content and some will have low moisture content, affecting product quality. As a result, the temperature of some coke is too high and it is very easy to spontaneously ignite.

[0003] The weight of the existing material guide is supported by fixing the peripheral channel steel. Under the action of positive stress in a high temperature environment for a long time, the channel steel will bend and deform, and cracks may appear at the weld. Once the channel steel is deformed too much and the weld is completely cracked, the material guide will fall off as a whole, making it impossible to distribute the raw coke evenly. In this case, the kiln can only be stopped for maintenance and the internal reinforcement can be entered. However, due to the difficulty and long cycle of maintenance, normal production will be greatly affected. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a material guide for a needle coke green coke drying kiln, so as to solve the problem of short service life of the existing material guide.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A material guide for a needle coke green coke drying kiln comprises a material guide umbrella, a cross beam and a material guide plate. Both the material guide umbrella and the material guide plate are provided with material guide inclined surfaces, and the two are coaxially arranged up and down. A cross beam is provided between the material guide umbrella and the material guide plate. The material guide umbrella and the material guide plate are respectively fixedly connected to the cross beam, and the end of the cross beam is fixedly connected to the inner wall of the green coke drying kiln.

[0007] The material guiding umbrella is conical, and its top angle is 105-115 degrees.

[0008] The material guiding umbrella is fixedly connected to the cross beam via a supporting frame, and the bottom of the material guiding umbrella is fixedly welded to the cross beam.

[0009] The material guide plate is annular, and the cross section of the annular portion is ridge-shaped.

[0010] The material guide plate is connected with the cross beam through a hook rod. The cross beam is provided with a round hole, in which the hook rod is inserted. The lower part of the hook rod penetrates into the material guide plate and is welded and fixed to the material guide plate.

[0011] The cross beams are cross-shaped.

[0012] A reinforcing beam is also provided between the end of the cross beam and the inner wall of the green coke drying kiln.

[0013] Compared with the existing technology, the beneficial effects of the utility model are:

[0014] The cross beam of the utility model provides stable support for the guide, has high strength, prevents the guide from falling off, and allows the raw coke to quickly slide on the guide umbrella and the guide plate, thereby improving the raw coke distribution effect and the guide efficiency. At the same time, the corrosion resistance is improved, which prolongs the service life of the guide. BRIEF DESCRIPTION OF THE DRAWINGS
