Description

Technical Field

[0001] The utility model relates to dust removal equipment for a coking coke intercepting car, in particular to an improved dust removal belt trolley connecting device for a coke intercepting car. Background Art

[0002] The coke-blocking car is a supporting equipment for the production and operation of the coke oven. It usually runs on the coke-blocking car rail 1 on the coke side of the coke oven (such as Figure 1 As shown in the figure, it is mainly used to open and close the coke side door of the coke oven, guide the hot coke pushed out of the coke oven charcoal chamber by the coke pusher to the coke tank of the coke quenching car, and collect the dust generated in the process of pushing the coke by the dust collecting hood 13 on the top of the coke intercepting car, and introduce it into the coke side dust removal pipeline 4 through the dust collecting belt trolley 6 installed on the belt car track 5 on the upper part of the coke side dust removal pipeline 4 of the coke oven, and finally sucked into the dust removal unit, and then subjected to dust removal treatment, so as to achieve the purpose of smoke and dust removal. In normal production, the driving wheel installed on the upper part of the coke intercepting car rail 1 and the driving wheel installed on the third rail 2 of the coke intercepting car jointly drive the coke intercepting car to move, and at the same time, with the help of the rectangular air duct 3 installed on the upper part of the dust collecting hood 13 of the coke intercepting car, the force is transmitted to the dust collecting belt trolley 6 through a rigid connection, so that the dust collecting belt trolley 6 moves on the belt car track 5, thereby forming a mobile dust collecting device to collect and treat the dust generated in the process of the coke intercepting car discharging. However, the belt track 5 is affected by the installation accuracy of the on-site equipment and the thermal expansion and contraction in the daily production process, and will be deformed. In addition, the dust-removing belt trolley 6 is rigidly connected to the square air duct 3 through the connecting rod 7 by welding. When running, the coke-blocking car rail 1 and the coke-blocking car third rail 2 will be inconsistent with the dust-removing belt trolley 6, causing the dust-removing belt trolley 6 to shake up and down on the belt track 5, so that the dust-removing belt trolley 6 derails, affecting the normal production and use of the coke-blocking car. At the same time, since the connecting rod 7 and the square air duct 3 are rigidly connected, fatigue fracture often occurs at the connection between the connecting rod 7 and the square air duct 3, which also accelerates the wear of the dust-removing belt, affects the service life, and increases the difficulty and cost of equipment maintenance. Utility Model Content

[0003] In order to solve the above problems, the utility model provides an improved dust removal belt trolley connecting device for the coke intercepting car to ensure that the dust removal belt trolley moves synchronously with the dust collection hood of the coke intercepting car, prevent the dust removal belt trolley from falling off the track due to the different tracks with the dust collection hood on the top of the coke intercepting car, improve the safe use of the dust removal belt trolley, and ensure smooth production.

[0004] The object of the present utility model is achieved in the following way. An improved connecting device for the dust removal belt trolley of a coke pushing car includes a flexible connecting pipe. The flexible connecting pipe is connected between the dust removal belt trolley and a square air duct. Two connecting rods are installed inside the dust removal belt trolley. The width between the two connecting rods is equal to the outer width at the outlet of the rectangular air duct. Frame structures in a frame shape are arranged on both sides at the outlet of the square air duct. Long rectangular frame grooves are arranged inside the frames. The outer ends of the connecting rods are inserted into the long rectangular frame grooves of the frames.

[0005] Further, the outer frame of the frame is in a "door" shape, with a crossbar arranged in the middle. The crossbar and the upper side bar of the outer frame form a long rectangular frame groove, and this long rectangular frame groove intersects perpendicularly with the connecting plate.

[0006] Further, the outer ends of the connecting rods extend 100 - 200 mm beyond the outer side of the frame.

[0007] The present utility model improves the connection structure between the dust removal belt trolley of the coke pushing car and the air duct outlet of the coke pushing car, avoiding the phenomenon that the dust removal belt trolley derails during the synchronous operation of the dust collection hood of the coke pushing car and the dust removal belt trolley, which affects the dust removal effect, prolonging the service life of the equipment, having a simple structure, stable operation, being easy for daily inspection and maintenance, and greatly reducing the maintenance difficulty and production cost of the equipment.

Detailed Embodiment

[0012] The following further describes the present utility model with reference to the drawings and embodiments. Refer to Figures 1 to 3, An improved connecting device for the dust removal belt trolley of a coke pushing car, which includes a flexible connection pipe 9. The flexible connection pipe 9 is connected between the dust removal belt trolley 6 and the rectangular air duct 3. Two connecting rods 7 are installed inside the dust removal belt trolley 6. The width between the two connecting rods 7 is equal to the outer width at the outlet of the rectangular air duct 3. Frame structures 8 in a frame shape are arranged on both sides at the outlet of the rectangular air duct 3. A long frame groove is provided inside the frame 8. The outer frame of the frame 8 is in a "door" shape, with a cross bar in the middle. The cross bar and the upper side bar of the outer frame form a long frame groove, and this long frame groove intersects perpendicularly with the connecting plate 7. The outer ends of the connecting rods 7 are inserted into the long frame groove of the frame 8, and the outer ends of the connecting rods 7 extend 100 - 200 mm beyond the outer side of the frame 8.

[0013] The flexible connection pipe 9 is made of wire mesh and high-temperature resistant material, further extending its service life.

[0014] Embodiment: Here is a preferred embodiment of the present invention for illustration. During normal production, the dust generated during the coke pushing process of the coke oven is collected by the dust collection hood 13 at the top of the coke pushing car, and is introduced into the coke side dust removal pipe 4 by the dust removal belt trolley 6 installed on the rail 5 above the coke side dust removal pipe of the coke oven, and finally sucked into the dust removal unit. After dust removal treatment, the purpose of smoke and dust elimination is achieved. When the coke pushing car moves on the coke side coke pushing car track 1 and the third rail 2 of the coke pushing car on the coke side of the coke oven, the dust collection hood on its upper part also moves accordingly, driving the dust removal belt trolley 6 installed on the belt trolley track 5 of the coke side dust removal pipe 4 to move. Since the track 1 on the coke side of the coke oven and the rail 5 above the coke side dust removal pipe of the coke oven are not completely parallel, the force transmitted to drive the dust removal belt trolley 6 through the dust collection hood 13 of the coke pushing car is transmitted to the dust removal belt trolley 6 only in the moving direction through this device, ensuring the synchronization between the dust removal belt trolley 6 and the dust collection hood 13 of the coke pushing car. And the deformation and expansion of the coke side coke pushing car track 1 and the third rail 2 of the coke pushing car on the coke side of the coke oven caused by the expansion of the coke oven body are compensated by the relative movement of the lever 7 up, down, front and back inside the mechanical frame 8 when passing through this device (as Figure 2 shown). The outer frame of the frame 8 is in a "door" shape, and a cross bar is welded in the middle. The cross bar and the upper side bar of the outer frame form a long frame groove, and this long frame groove intersects perpendicularly with the connecting plate 7. And the outer ends of the connecting rods 7 extend 200 mm beyond the outer side of the frame 8. At the same time, a flexible connection pipe 9 is used between the rectangular air duct 3 and the dust removal belt trolley 6, reducing the blockage of the driving direction of the travel wheels 10 of the belt dust removal trolley transmitted by the rectangular air duct, ensuring the engagement between the guide wheels 12 of the dust removal belt trolley and the dust removal sealing belt 11, preventing the dust removal sealing belt 11 from running off track, and improving the service life of the dust removal sealing belt 11. This enables the smoke and dust to smoothly pass through the dust removal belt trolley 6 and be introduced into the coke side dust removal pipe 4 of the coke oven (as Figure 3 shown), and directly sent to the ground dust removal station for purification treatment, improving the sealing performance of the rectified dust removal system.

[0015] The utility model can achieve the purpose that the dust removal car body trolley and the dust collection hood of the coke pushing car run on different tracks respectively and can also move synchronously, ensuring that the dust removal belt trolley closely follows the dust collection hood of the coke pushing car to move synchronously, and well solving the problem of walking deviation existing in the operation process of the dust removal belt trolley of the coke side coke pushing car of the coke oven. The soot collected by the dust collection hood of the coke pushing car during the coke pushing process is smoothly introduced into the coke side dust removal pipeline through the dust removal belt trolley, and finally inhaled into the dust removal unit. After dust removal treatment, the soot is eliminated, avoiding the pollution of the environment caused by the diffusion of the soot into the atmosphere. The device has a simple structure, stable operation, does not require special maintenance and overhaul, and the operation and maintenance cost is almost zero.
