Description

Technical Field

[0001] The utility model relates to the technical field of coke production, in particular to a spraying machine for a coke oven. Background Art

[0002] At present, a coke oven is a thermal equipment used to carbonize coal to produce coke. After long-term use, cracks will appear on the outer wall of the coke oven. To avoid danger caused by damage to the coke oven, a spraying machine is generally used to spray slurry to repair the outer wall of the coke oven.

[0003] Among them, through retrieval, a Chinese patent with the publication number of CN220926669U discloses a spraying machine for a coke oven. The above patent realizes the function of stirring the slurry in the tank through a structural scheme combining two methods of stirring and tumbling driven by bubbles. However, since the nozzle is located inside the tank, it is easy for the slurry to enter the nozzle, resulting in a potential risk of blockage. Therefore, for the progress of the industry technology, to better realize the function of stirring the slurry in the tank and improve the core technology competitiveness, this application proposes a new implementation scheme different from the structure and method of stirring the slurry in the existing spraying machine. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the slurry is easy to enter the nozzle inside the tank of the existing spraying machine, and a spraying machine for a coke oven is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A spraying machine for a coke oven, including a fixed seat. One side inner wall of the fixed seat is rotatably connected with a tank body. The top of the tank body is fixedly connected with a feeding pipe. The top end of the feeding pipe is threadedly and sealingly sleeved with a sealing cover. And a spraying pipe is fixedly connected to the outer surface of the feeding pipe. The two ends of the tank body are respectively rotatably inserted with a rotating cylinder. The outer surfaces of the two rotating cylinders are fixedly connected with the same scraping plate. A rotating shaft is rotatably inserted between the two rotating cylinders. And a plurality of stirring rods are fixedly connected to the outer surface of the rotating shaft. The bottom of the tank body is fixedly connected with an air pump. The air output end of the air pump is sealingly inserted with two air outlet pipes. One end of the air outlet pipe is fixedly connected to the outer surface of the tank body. And a valve body is arranged on the air outlet pipe.

[0007] Further, two inclined surface cylinders are fixedly connected to the inner surface of the tank body. And the outer surface of the scraping plate is respectively in contact with the corresponding inclined surface cylinder and the inner surface of the tank body.

[0008] Further, a side seat is fixedly connected to one side of the tank body. And a first motor and a second motor are fixedly connected to the bottom of the side seat.

[0009] Further, the output end of the first motor and one end of the rotating shaft are connected by a coupling.

[0010] Further, driving gears are respectively fixedly connected to the outer surface of one of the rotating cylinders and the output end of the second motor, and the two driving gears are meshed with each other.

[0011] Further, a worm gear is fixedly connected to one end of the tank body, a worm is rotatably inserted into the inner wall of one side of the fixed seat, and the worm is meshed with the worm gear.

[0012] Further, a support seat is fixedly connected to the inner wall of the bottom of the fixed seat, and the worm is rotatably connected to the upper surface of the support seat.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. Through the design of the separate rotation of the scraper and the stirring rod, while the stirring rod stirs the slurry in the tank body, the scraper scrapes up the slurry at the bottom of the tank body, so as to avoid the precipitation of the slurry in the tank body. The combination of the scraper and the stirring rod is different from the stirring and pneumatic tumbling in the prior art. While ensuring the full stirring of the slurry in the tank body, it can avoid the blockage of the internal structure by the slurry in the tank body and ensure the stirring effect of the slurry in the shotcreting machine.

[0015] 2. Through the design of the rotatable connection of the tank body, the position of the material passing pipe on the tank body can be adjusted. In this way, when stirring the slurry, the material passing pipe is above the tank body, avoiding the remaining un-stirred slurry in the material passing pipe. When shotcreting, the material passing pipe is located below the tank body, and the slurry can be discharged through the spraying pipe on the material passing pipe, ensuring the practicability of the use of the shotcreting machine.

[0016] 3. Through the design of the inclined surface cylinder, the slurry in the tank body can be concentrated towards the center of the tank body under the guidance of the inclined surface cylinder, reducing the remaining slurry in the tank body after shotcreting and avoiding the waste of the slurry in the tank body.

Specific implementation mode

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] Refer to Figures 1 - 5 , a coking furnace spraying machine, including a fixed seat 1. One side inner wall of the fixed seat 1 is rotatably connected with a tank body 2. The top of the tank body 2 is fixedly penetrated and inserted with a material passing pipe 3. The top end of the material passing pipe 3 is threadedly and sealingly sleeved with a sealing cover 301. And the outer surface of the material passing pipe 3 is fixedly penetrated and inserted with a spraying pipe 4. Through the design of rotatably connecting the tank body 2, the position of the material passing pipe 3 on the tank body 2 can be adjusted. In this way, when stirring the slurry, the material passing pipe 3 is above the tank body 2, avoiding the residue of un-stirred slurry in the material passing pipe 3. And when spraying the slurry, the material passing pipe 3 is located below the tank body 2, and the slurry can be discharged through the spraying pipe 4 on the material passing pipe 3. One end of the tank body 2 is key-connected with a worm gear 17. One side inner wall of the fixed seat 1 is rotatably inserted with a worm 18. And the worm 18 is engaged with the worm gear 17. The cooperation of the worm 18 and the worm gear 17 facilitates the operation of people to rotate the tank body 2. The bottom inner wall of the fixed seat 1 is fixedly bolted with a support seat 19. And the worm 18 is rotatably connected to the upper surface of the support seat 19. The support seat 19 can support the worm 18 to ensure the stable rotation of the worm 18.

[0025] One side of the tank body 2 is fixed with a side seat 13 by bolts, and the bottom of the side seat 13 is fixed with a first motor 14 and a second motor 15 by bolts. The two ends of the tank body 2 are respectively rotatably inserted with rotating cylinders 5. The outer surfaces of the two rotating cylinders 5 are fixed with the same scraping plate 6 by bolts. The outer surface of one of the rotating cylinders 5 and the output end of the second motor 15 are respectively key-connected with transmission gears 16, and the two transmission gears 16 are meshed with each other. The second motor 15 and the transmission gears 16 cooperate to drive the rotation of the rotating cylinder 5 and the scraping plate 6 thereon. A rotating shaft 7 is rotatably inserted between the two rotating cylinders 5, and a plurality of stirring rods 8 are fixed on the outer surface of the rotating shaft 7 by bolts. The output end of the first motor 14 and one end of the rotating shaft 7 are connected by a coupling. The first motor 14 is used to drive the rotation of the rotating shaft 7 and the stirring rods 8 thereon. Through the design of the separate rotation of the scraping plate 6 and the stirring rods 8, while the stirring rods 8 stir the slurry in the tank body 2, the scraping plate 6 scrapes up the slurry at the bottom of the tank body 2, so as to avoid the precipitation of the slurry in the tank body 2.

[0026] Wherein, two inclined surface cylinders 9 are welded on the inner surface of the tank body 2, and the outer surfaces of the scraping plates 6 are respectively in contact with the corresponding inclined surface cylinders 9 and the inner surface of the tank body 2. Through the design of the inclined surface cylinders 9, the slurry in the tank body 2 is concentrated towards the center of the tank body 2 under the guidance of the inclined surface cylinders 9, reducing the residue of the slurry after spraying in the tank body 2 and avoiding the waste of the slurry in the tank body 2.

[0027] At the same time, an air pump 10 is fixed at the bottom of the tank body 2 by bolts. The air delivery end of the air pump 10 is hermetically inserted with two air outlet pipes 11. One end of the air outlet pipe 11 is fixedly inserted through the outer surface of the tank body 2, and a valve body 12 is arranged on the air outlet pipe 11. The design of the valve body 12 can close the air outlet pipe 11 to prevent the slurry in the tank body 2 from entering the air outlet pipe 11 and avoid blockage of the air outlet pipe 11. The air pump 10 can generate air power to convey air into the tank body 2 through the air outlet pipes 11, so that pressure is generated in the tank body 2. In this way, the slurry in the tank body 2 can be quickly sprayed out under the action of air pressure.

[0028] Working principle of this embodiment: When in use, the operator can inject slurry into the tank body 2 through the feed pipe 3, and when the slurry in the tank body 2 is stirred, the operator can start the first motor 14 and the second motor 15 respectively. At this time, the rotating shaft 7 and the stirring rod 8 thereon rotate, and the rotating cylinder 5 and the scraper 6 thereon also rotate under the action of the transmission gear 16. The rotation of the stirring rod 8 can stir the slurry in the tank body 2, and the scraper 6 can scrape up the slurry on the inner wall and bottom of the tank body 2 to avoid the precipitation of the slurry in the tank body 2; and when spraying is required, the operator twists the worm 18, and then drives the worm wheel 1 7 and the tank body 2 connected thereto rotate until the feed pipe 3 is located at the bottom of the tank body 2. At this time, the injection pipe 4 is also located at the bottom of the tank body 2. One end of the feed pipe 3 is then aligned with the crack of the coke oven. The operator then starts the air pump 10 and opens the valve body 12. At this time, the air force generated by the air pump 10 is input into the tank body 2 through the air outlet pipe 11, and the slurry in the tank body 2 is sprayed out from the injection pipe 4 under the action of air pressure. After the slurry in the tank body 2 is discharged, the operator can remove the sealing cover 301, and use the scraper 6 to scrape off the residual slurry inside the tank body 2 and discharge it through the feed pipe 3, so that the inside of the tank body 2 can be cleaned.
