Description

Technical Field

[0001] This utility model relates to the field of experimental coke oven technology, specifically to a smoke prevention device for the oven door of a 40kg bottom-charged experimental coke oven. Background Technology

[0002] Currently, the sealing of coke oven doors in bottom-charging tests mainly relies on the compression of hydraulic lifting vehicles. However, due to tar dripping from the coking coal and the accumulation of dust and stones, the compression surface becomes uneven, affecting the sealing effect and leading to smoke and air intrusion. Coking flue gas is toxic, impacting environmental protection and human health. Furthermore, the intrusion of air can burn carbon in the coal, affecting the accuracy of test data. Therefore, the compression surface of the hydraulic lifting vehicle needs to be manually cleaned periodically, but this involves high-temperature operations, posing safety hazards, and is time-consuming and labor-intensive. Therefore, these problems urgently need to be addressed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a smoke prevention device for the furnace door of a 40kg bottom-charged coke oven. First, a first seal is achieved by the extrusion contact between the extrusion block and the extrusion plane of the test coke oven body. Then, a second seal is achieved by the cooperation of the water seal plate, water tank and water, thereby ensuring the sealing effect of the furnace door. This not only avoids the phenomenon of smoke escaping due to poor furnace door sealing, but also reduces the frequency of cleaning tar and ash on the extrusion block and reduces labor intensity.

[0008] Preferably, the length of each of the four water seal plates is greater than the corresponding side length of the groove, and the square area they enclose is centrally located with the groove as the center, thereby ensuring that the water seal plates do not interfere with the extrusion contact action of the extrusion block and the extrusion plane of the test coke oven body.

[0009] Preferably, each of the water tanks is a long strip that matches the water seal plate, and its width is greater than the width of the corresponding water seal plate, its length is greater than the length of the corresponding water seal plate, and its depth is greater than the height of the corresponding water seal plate; the two ends of the four water tanks are connected to each other, and each water tank is centrally located relative to the corresponding water seal plate, so that when the extrusion block and the extrusion plane are in contact, the four water seal plates are respectively inserted into the corresponding water tanks, and the furnace door is double-sealed by the water seal.

[0010] Preferably, the water level in the four water tanks must be higher than the horizontal plane of the lower end face of the water seal plate to ensure the water seal effect.

[0011] Preferably, it also includes a water tank, a circulation pump, and a water injection pipe; a water tank with an open upper surface is horizontally fixed on the upper surface of the lifting plate of the hydraulic lifting vehicle relative to the right side of the fixed block, and a circulation pump is also provided between the upper surface of the lifting plate relative to the fixed block and the water tank, ensuring that the height of the water tank is less than the height of the fixed block; a water injection channel is vertically embedded on the right side of the fixed block relative to the bottom of the corresponding water tank, and one end of the water injection channel is sealed and connected to the circulation pump through the water injection pipe; the other end of the water injection channel extends towards the right side of the water tank in the form of several branches, and is connected to the right side of the water tank respectively, so that the water in the water tank is pumped into the water tank through the water injection channel by the circulation pump.

Detailed Implementation

[0020] The technical solution of this utility model will be clearly and completely described below through specific embodiments.

[0021] This utility model discloses a smoke prevention device for the furnace door of a 40kg bottom-charged coal test coke oven, comprising a hydraulic lifting vehicle 1, a fixing block 8, a pressing block 7, a furnace door brick 6, and a water seal plate 5; the specific structure is as follows: Figure 1 , Figure 2 As shown, the hydraulic lifting vehicle 1 is horizontally arranged, and a fixing block 8 is horizontally fixed at the middle left position of the upper surface of its lifting plate. An extrusion block 7 is horizontally fixed on the upper surface of the fixing block 8 relative to the furnace door 3. The extrusion block 7 and the fixing block 8 are integrally formed. A furnace door brick 6 matching the furnace door 3 is horizontally fixed on the upper surface of the extrusion block 7 relative to the furnace door 3. A groove 4 matching the extrusion block 7 is vertically embedded in the bottom surface of the test coke oven body 2 relative to the position of the extrusion block 7, and the groove 4 is connected to the furnace door 3. Water seal plates 5 are vertically and parallelly fixed on the bottom surface of the test coke oven body 2 relative to the outer perimeter of the groove 4, and the two ends of the four water seal plates 5 are sealed to each other, thus forming a square area. A water trough 9 matching the water seal plate 5 is vertically embedded in the upper surface of the fixing block 8 relative to each water seal plate 5, and the four water troughs 9 are connected to each other and filled with water. The hydraulic lifting vehicle 1 is an existing product, so its structure will not be described in detail here.

[0022] like Figure 1 , Figure 2 As shown, the extrusion block 7 is a square shape that matches the furnace door 3, and the length of its four sides is greater than the corresponding side length of the furnace door 3. It is centered relative to the furnace door 3, so that when the furnace door brick 6 is inserted into the carbonization chamber of the test coke oven body 2 through the furnace door 3, the extrusion block 7 can extrude and seal the furnace door 3.

[0023] like Figure 1 , Figure 2 As shown, the groove 4 is a square shape that matches the extrusion block 7 and is centered relative to the furnace door 3, thus forming the extrusion plane of the test coke oven body 2; the length of all four sides of the groove 4 is greater than the corresponding side length of the extrusion block 7, and its opening depth is less than the thickness of the extrusion block 7, thus achieving a first seal on the furnace door 3 through the extrusion contact between the extrusion block 7 and the extrusion plane of the test coke oven body 2.

[0024] like Figure 1 , Figure 2 As shown, the fixing block 8 has a square structure, and the lengths of its four sides are greater than the corresponding side lengths of the groove 4, and it is centered relative to the extrusion block 7.

[0025] like Figure 1 , Figure 2As shown, the lengths of the four water seal plates 5 are all greater than the corresponding side lengths of the groove 4, and the square area they enclose is centered on the groove 4, thereby ensuring that the water seal plates 5 do not interfere with the extrusion contact action of the extrusion block 7 and the extrusion plane of the test coke oven body 2.

[0026] like Figure 1 , Figure 2 As shown, each water tank 9 is a long strip that matches the water seal plate 5, and its width, length, and depth are all greater than the width, length, and height of the corresponding water seal plate 5. The two ends of the four water tanks 9 are connected to each other, and each water tank 9 is centered relative to the corresponding water seal plate 5. Thus, when the extrusion block 7 is in contact with the extrusion plane, the four water seal plates 5 are inserted into the corresponding water tanks 9 respectively, and a double seal is achieved for the furnace door 3 through the water seal. The water level in the four water tanks 9 must be ensured to be higher than the horizontal plane of the lower end face of the water seal plate 5 to ensure the water seal effect.

[0027] This utility model also includes a water tank 14 with an open upper surface, horizontally fixed on the upper surface of the lifting plate of the hydraulic lifting vehicle 1 relative to the right side of the fixed block 8. Furthermore, a circulation pump 15 is provided between the upper surface of the lifting plate and the water tank 14 relative to the fixed block 8, ensuring that the height of the water tank 14 is less than the height of the fixed block 8. Figure 1 , Figure 2 As shown, a water injection channel 10 is vertically embedded on the right side of the fixed block 8 relative to the bottom of the corresponding water tank 9. One end of the water injection channel 10 is sealed and connected to the circulation pump 15 through the water injection pipe 11. The other end of the water injection channel 10 extends towards the right side water tank 9 in the form of several branches and is connected to the right side water tank 9 respectively. Then, the water in the water tank 14 is pumped into the water tank 9 through the water injection channel 10 by the circulation pump 15.

[0028] like Figure 1 , Figure 2 As shown, an overflow channel 12 is vertically embedded on the right side of the fixed block 8 near its upper surface. One end of the overflow channel 12 is sealed and connected to one end of the overflow pipe 13. The other end of the overflow pipe 13 extends downward at an angle to the upper surface of the water tank 14 and is fixedly attached to the left edge of the upper surface of the water tank 14. The other end of the overflow channel 12 extends towards the right-side water tank 9 in the form of several branches and is connected to the right-side water tank 9 respectively. It is ensured that its position is higher than the horizontal plane where the lower end of the water seal plate 5 is located. Thus, through the cooperation of the overflow channel 12 and the overflow pipe 13, the excess water in the water tank 9 is returned to the water tank 14.

[0029] The working principle of this utility model:

[0030] When the furnace door 3 needs to be sealed, the lifting plate of the hydraulic lifting vehicle 1 rises, so that the furnace door brick 6 is inserted into the carbonization chamber of the test coke oven body 2 through the furnace door 3. At this time, the extrusion block 7 is pressed and contacted with the extrusion plane of the test coke oven body 2, thereby achieving a first seal; at the same time, the water seal plate 5 is vertically inserted into the water tank 9, thereby achieving a second seal through the water in the water tank 9.

[0031] Because the furnace door 3 is a high-temperature environment, the water in the water tank 9 will evaporate. Therefore, every once in a while, the water in the water tank 14 needs to be pumped into the water tank 9 by the circulation pump 15 to replenish it. If the water level in the water tank 9 is too high, it will flow back into the water tank 14 through the overflow channel 12 and the overflow pipe 13, thereby avoiding unnecessary waste.

[0032] The beneficial effects of this utility model are:

[0033] (1) This utility model first seals the furnace door 3 by extruding the extrusion block 7 into the extrusion plane of the test coke oven body 2, and then seals it by combining the water seal plate 5, the water tank 9 and water. This ensures the sealing effect of the furnace door 3, not only avoiding the phenomenon of flue gas escaping due to poor sealing of the furnace door 3, but also reducing the frequency of cleaning tar and ash on the extrusion block 7 and reducing labor intensity.

[0034] (2) This utility model forms a water circulation by cooperating water tank 14, circulation pump 15, water injection pipe 11, water injection channel 10, overflow channel 12 and overflow pipe 13, thereby avoiding the phenomenon that the liquid level in water tank 9 drops due to high temperature at furnace door 3, thus affecting the water seal effect.

[0035] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the concept and scope of the present utility model. Without departing from the design concept of the present utility model, all modifications and improvements made by those skilled in the art to the technical solutions of the present utility model should fall within the protection scope of the present utility model. The technical content for which protection is sought in the present utility model has been fully recorded in the technical requirements.
