Description

Technical Field

[0001] The utility model relates to the technical field of industry, in particular to a coke oven gas to methanol conversion furnace. Background Art

[0002] The so-called coal blending for coking is to evenly blend two or more types of coal in a certain proportion for coking. The blended coal is made into coke by high-temperature dry distillation in the coke oven. In the coke oven, the only coal that can be made into coke alone is coking coal, but due to the limited reserves of coking coal, it cannot meet the demand. In addition, during the coking process, the coke cake shrinks little and it is difficult to push the coke; in particular, during the coking process, coking coal generates a large expansion pressure, which has a great damage to the coke oven body; coking coal has a low volatile content, and the yield of coal gas and chemical products is also low. Therefore, using a variety of coals for coking can not only save high-quality coking coal and expand the resources of coking coal, but also make full use of the performance advantages of various coals to improve the quality of coke, and at the same time increase the yield of coking chemical products and the amount of coal gas generated, which is beneficial to the operation of the coke oven and prolonging the service life of the coke oven.

[0027] The sliding groove 31 is provided to limit the movement of the slider 32 .

[0028] There are three trapezoidal top blocks 37 and three rollers 38. The three trapezoidal top blocks 37 are fixedly connected to the top of the turntable 36 and are evenly arranged in a circular sequence. The three rollers 38 are fixedly connected to the bottom of the box body 33 and are evenly arranged in a circular sequence.

[0029] Specifically, the motor 34 drives the vertical shaft 35 to rotate, and the rotation of the vertical shaft 35 drives the box body 33 to move up and down, and generates vibration to turn over the coke inside.

[0030] Embodiment 2

[0031] like Figure 1-4 As shown, a rolling mechanism 4 is arranged inside the box body 2, and the rolling mechanism 4 includes a sieve plate 41, which is fixedly connected to the inside of the box body 2 and arranged in a shape of being lower on the left and higher on the right. An inclined plate 42 is fixedly connected to the bottom of the sieve plate 41 and arranged in a shape of being higher on the left and higher on the right.

[0032] By providing the screen plate 41 , small volumes of coke can be screened directly into the coke oven 1 .

[0033] A slide rod 43 is fixedly connected to the left inner wall of the box body 2, and a movable plate 44 is slidably penetrated through the middle of the slide rod 43. A spring 45 is sleeved on the outside of the slide rod 43. The left end of the spring 45 is fixedly connected to the left inner wall of the box body 2, and the right end of the spring 45 is fixedly connected to the movable plate 44. A cam 46 is fixedly connected to the top end of the vertical shaft 35, and one side of the cam 46 is slidably connected to the movable plate 44.

[0034] The spring 45 is provided to drive the movable plate 44 to return to its original position.

[0035] Two groups of pressing plates 47 are fixedly connected to the left inner wall of the box body 2 and the left side of the movable plate 44 and are arranged alternately.

[0036] The two sets of pressing plates 47 are driven by the cam 46 to move closer to each other, but a gap is still left between them, so that a large volume of coking coal can be crushed but the coking coal is prevented from being crushed too much.

[0039] The working principle of the utility model is as follows:

[0040] First, start the motor 34 to drive the vertical shaft 35 to rotate, and the rotation of the vertical shaft 35 drives the cam 46 to rotate. During the rotation of the cam 46, the movable plate 44 is pushed to the left, and the movable plate 44 moves to the left, driving the right pressure plate 47 to move to the left and compressing the spring 45. Then the spring 45 rebounds and drives the movable plate 44 to return. As a result, the movable plate 44 moves back and forth left and right, and at the same time, coking coal is put into the box body 2 and sieved through the sieve plate 41. The small volume of coking coal passes through the sieve plate 41 and directly falls into the box body 33 to avoid being pressed into smaller pieces by the pressure plate 47, while the large volume of coking coal is crushed into small pieces by the pressure plate 47 and then falls into the box body 33. The rotation of the vertical shaft 35 drives the turntable 36 to rotate, and the rotation of the turntable 36 drives the trapezoidal top block 37 to rotate. The trapezoidal top block 37 contacts the roller 38 while rotating and lifts it up. After the roller 38 is pushed to the bottom, it drives the box body 33 to move up and down, and generates vibration to turn over the heated coking coal in the box body 33.
