Description

Technical Field

[0001] This utility model relates to the field of drying kiln technology, and in particular to a drying kiln structure. Background Technology

[0002] The charcoal drying tower system is responsible for producing coke and semi-coke, the raw materials for the calcium carbide furnace. During the drying process, material tends to accumulate on the bottom plate of the charcoal drying tower, resulting in red material. This leads to high charcoal temperatures during production, causing a high failure rate in the semi-coke drying tower system. At least three mid-term repairs are required each year, which seriously affects the equipment's operating rate. Utility Model Content

[0003] This invention addresses the technical problem of material accumulation in existing drying towers, which leads to increased high-temperature frequency in the drying kiln and affects equipment operation, by providing a drying kiln structure.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] A drying kiln structure includes a drying tower and an air inlet main. The air outlet end of the air inlet main is connected to the top of the drying tower, and at least one air inlet branch pipe is provided between the air inlet main and the drying tower. One end of each air inlet branch pipe passes through the side wall of the air inlet main and is connected to the air inlet main, and the other end passes through the side wall of the drying tower and is connected to the drying tower. Each air inlet branch pipe is equipped with a branch pipe air distribution valve.

[0006] The beneficial effects of this utility model are as follows: During operation, ventilation is directed into the drying tower through the main air inlet pipe and each air inlet branch pipe connected to the drying tower to reduce the temperature of the drying tower. At the same time, the unit air volume discharged into each part of the drying tower through each air inlet branch pipe is regulated by the air distribution valve of each branch pipe to control the temperature inside the drying tower. This improves the existing technical problem that material accumulation in the drying tower easily leads to an increase in the frequency of high temperature in the drying kiln body, which affects the operation of the equipment.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, at least two air inlet branch pipes are provided, and each air inlet branch pipe is vertically spaced at the middle and lower ends of the drying tower.

[0009] The beneficial effects of adopting the above-mentioned further solution are: ventilation is simultaneously directed towards the middle and lower ends of the drying tower through each air inlet branch pipe set at the middle and lower ends of the drying tower, and during this process, the air volume entering the middle and lower ends of the drying tower can be directly adjusted through the air distribution valve of each branch pipe, which directly improves the problem of material accumulation and red material phenomenon on the bottom plate of the drying tower.

[0010] Furthermore, on the same horizontal plane, at least two air inlet branch pipes are provided at intervals.

[0011] The beneficial effects of adopting the above-mentioned further scheme are: there are at least two air inlet branch pipes on the same horizontal plane, which can simultaneously adjust the temperature of the corresponding section of the drying tower. At the same time, the air volume can be adjusted by multiple air distribution valves on each branch pipe on the same horizontal plane, so as to achieve fine control of the temperature of the drying tower at that end.

[0012] Furthermore, it also includes a top air inlet pipe, one end of which is connected to the air outlet of the main air inlet pipe, and the other end is connected to the top of the drying tower, and the top air inlet pipe is equipped with an air distribution valve for the main air inlet pipe.

[0013] The beneficial effects of adopting the above-mentioned further scheme are: to ventilate the top of the drying tower through the top air inlet pipe, and at the same time to regulate the air volume entering the top of the drying tower using the air distribution valve of the main air inlet pipe.

[0014] Furthermore, it also includes an exhaust duct, which is equipped with an exhaust main valve, and the air inlet is connected to the drying tower, while the air outlet is connected to a dust collector.

[0015] The beneficial effects of adopting the above-mentioned further scheme are: to realize the exhaust of air in the drying tower through the exhaust duct, and to control the exhaust volume of air in the drying tower by using the air distribution valve of the main exhaust pipe, thereby maintaining the temperature control in the drying tower, and at the same time to regulate the dust collector by using the air distribution valve of the main exhaust pipe.

[0016] Furthermore, the exhaust duct includes multiple exhaust branch pipes, a collection pipe that is closed at both ends, and a main exhaust pipe. The multiple exhaust branch pipes are arranged vertically at intervals, and their air inlets are all connected to the drying tower, and their air outlets are all connected to the collection pipe. The air inlet of the main exhaust pipe is connected to the collection pipe, and its air outlet is connected to the dust collector. The air distribution valve of the main exhaust pipe is configured on the main exhaust pipe.

[0017] The beneficial effects of adopting the above-mentioned further scheme are: during the operation, multiple vertically arranged exhaust branch pipes promptly discharge the air from each section of the drying tower, so as to achieve precise temperature regulation inside the drying tower. During the regulation process, the exhaust speed can be uniformly controlled through the exhaust manifold distribution valve.

[0018] Furthermore, a three-way valve is configured in the middle section of the air collection duct, and the two air inlets of the three-way valve are respectively connected to the upper and lower sections of the air collection duct, the air outlet of the three-way valve is connected to the air inlet of the exhaust main duct, and each of the exhaust branch pipes arranged vertically is located on the upper and lower sides of the three-way valve.

[0019] The beneficial effect of adopting the above-mentioned further solution is that by opening and closing the three-way valve, the exhaust branch pipes located above or below the three-way valve can be controlled to perform exhaust operations, thereby realizing the rapid adjustment of the air volume at the top or bottom of the drying tower.

[0020] Furthermore, the height of the exhaust branch pipe at the lowest position is higher than the height of the air inlet branch pipe at the lowest position.

[0021] The beneficial effect of adopting the above-mentioned further solution is that the air entering the drying tower from the lowest position air inlet branch pipe can be quickly discharged through the exhaust branch pipe.

[0022] Furthermore, on the same horizontal plane, at least two exhaust branch pipes are provided at intervals.

[0023] The beneficial effect of adopting the above-mentioned further scheme is that there are at least two exhaust branch pipes on the same horizontal plane, which can simultaneously adjust the temperature of the corresponding section of the drying tower.

[0024] Furthermore, the sidewall of the drying tower is provided with multiple observation holes spaced vertically.

[0025] The advantages of adopting the above-mentioned further scheme are: it facilitates the inspection of the material feeding situation in the kiln through each observation hole, and it also facilitates the operation personnel to inspect and maintain each section of the rotary blades in the kiln through each observation hole.
