Two blocking wheels 35 arranged symmetrically forward and backward are provided in the middle of the rear supporting wheel cover 32. The design of the stop wheel 35 is convenient for sensing and transmitting the position signal of the rotary kiln shell 1 during operation, so that the operator can make adaptive adjustments to the rotary kiln shell 1 in time to ensure the normal operation of the rotary kiln shell 1.
[0038] The present invention adopts the design of the feeding center cylinder 111, the feeding isolation plate 112 and the feeding lifting plate 113 in the feeding rotary cylinder 11, and the discharging center cylinder 121 and the outlet The design of the material isolation plate 122 and the discharge lifting plate 123 effectively reduces the material drop in the rotary kiln shell 1, greatly reduces the damage rate of the material, and ensures the material and hot air inside the rotary kiln shell 1 The full contact of the material makes the moisture in the material reach the standard, improves the drying efficiency of the material, and satisfies the feeding amount of some bulk materials. At the same time, the design of the feeding lifting plate 113 on both sides of the feeding isolation plate 112 and the design of the discharging lifting plate 123 on both sides of the discharging isolation plate 122 can provide good support and support for materials of various sizes. The material is copied so that the material in the rotary kiln shell 1 is in full contact with the hot air of the rotary kiln shell 1, so as to ensure the drying efficiency of the material in the rotary kiln shell 1. In addition, the design of the feeding lifting plate 113 in the feeding center cylinder 111 and the discharging lifting board 123 of the discharging center cylinder 121 can make the feeding center cylinder The materials in the 111 and the discharging center cylinder 121 are in full contact with the hot air, which ensures the drying efficiency of the materials in the feeding center cylinder 111 and the discharging center cylinder 121.
[0039] Take the drying treatment of blue charcoal in a factory as an example. Before the improvement, the damage rate of the blue charcoal was as high as 15% due to the large drop of the blue charcoal; after the improvement, the blue charcoal was treated by the horizontal drying kiln structure, which was rotated. The number of the feed isolation plate 112 and the discharge isolation plate 122 of the kiln shell 1 are both 6, which can reduce the damage rate of the blue charcoal to 7%-9%. In addition, by adopting the structure of this horizontal drying kiln, the feeding speed can be increased by about twice as long as the discharge parameters are fully up to standard. The main purpose of the structure of the horizontal drying kiln is to reduce the damage rate of the blue charcoal and increase the drying capacity. Under the full-load working condition, the kiln can discharge 18 tons/hour, and the production efficiency is doubled. The damage rate of blue charcoal has decreased by 7%-9%. As far as the current price of blue charcoal is concerned, medium particles (18-38mm) are 750 yuan/ton, and coke (0-6mm) is 500 yuan/ton, working 24 hours a day. It can be calculated that a stove can save more than before: 18*8%*(750-500)=288 yuan/hour. It saves 6912 yuan per day, 207,000 yuan per month (10 months per year, there are two months for maintenance), and 2 million yuan per year. Now the chemical plant has been transformed into 2 units, and there are 3 units, a total of 5 units. If all 5 units are transformed, more than 10 million yuan can be saved each year.
