Description

Technical Field

[0001] This utility model relates to the field of drainage technology, specifically a novel sealing device for the kiln head of a dry process kiln. Background Technology

[0002] Dry-process rotary kilns are thermal equipment used to produce umbrella-shaped or slurry-like materials, widely used in non-ferrous metallurgy, refractory materials, cement, and chemical industries. They are classified according to the materials processed, such as cement kilns, lime kilns, and metallurgical / chemical kilns. In the cement industry, the sealing performance of the kiln head directly affects the company's production capacity and energy consumption. If air leakage or flying sand occurs during cement production, it not only causes significant environmental pollution but also disrupts the normal operating conditions of the kiln system and reduces clinker production efficiency.

[0003] Existing devices primarily seal the kiln head of a rotary kiln using components such as sealing rings. Many existing technologies are similar to the novel rotary kiln head design, exemplified by patent number CN221376261U, which includes a kiln body with a support frame on one side. A mounting frame is fixedly connected to one side of the support frame, and the mounting frame and cooling nozzles are distributed in a circular, equally spaced pattern around one side of the support frame. This device can prevent the sealing ring from overheating, thus ensuring its service life and sealing effect. However, there are still areas for improvement in this device.

[0004] Existing devices mainly use components such as friction rings to dynamically seal the kiln head and kiln casing. This makes some devices prone to wear and gaps after long-term operation, making it difficult to stably seal the kiln head. In addition, some devices place the friction ring between the kiln head and the kiln casing, making it difficult to disassemble and assemble the sealing components. This makes it inconvenient to replace severely worn friction rings, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a new sealing device for the kiln head of dry process kilns is proposed. Summary of the Invention

[0005] The purpose of this utility model is to provide a novel sealing device for the kiln head of a dry process kiln, in order to solve the problems mentioned in the background art. The existing devices mainly use components such as friction rings to dynamically seal the kiln head and kiln casing, which makes some devices prone to wear and gaps after long-term operation, thus making it difficult to stably seal the kiln head. At the same time, some devices mainly place the friction ring between the kiln head and the kiln casing, making it difficult to disassemble and install the sealing components, thus making it inconvenient to replace the severely worn friction ring.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel sealing device for the kiln head of a dry process kiln, comprising a kiln cylinder, a kiln head sleeved on the left side of the outer wall of the kiln cylinder, an air chamber fixedly connected to the left side of the outer wall of the kiln head, a control air valve fixedly connected to the front side of the outer wall of the air chamber, a vacuum pump fixedly connected to the bottom of the control air valve, a traction frame provided on the right side of the air chamber, and a mounting frame attached to the right side of the traction frame.

[0007] A sealing mechanism is provided on the right side of the air chamber. The sealing mechanism includes an air cylinder. The left side of the air cylinder is fixedly connected to the right side of the air chamber. An assembly mechanism is provided inside the mounting frame. The assembly mechanism includes a sleeve. The left side of the outer wall of the sleeve is fixedly connected to the right side of the mounting frame.

[0008] Preferably, a piston is slidably connected to the inner wall of the air cylinder, and a traction rod is fixedly connected to the middle right side of the piston. The right end of the traction rod passes through the air cylinder and is fixedly connected to the left side of the traction frame.

[0009] Preferably, a friction ring is fixedly connected to the inner wall of the mounting frame, and a limiting ring is fitted to the inner wall of the friction ring. The inner wall of the limiting ring is fixedly connected to the left side of the outer wall of the kiln cylinder.

[0010] Preferably, a sealing ring is fixedly connected to the left side of the outer wall of the mounting frame, and the outer wall of the sealing ring is attached to the right side of the inner wall of the kiln head.

[0011] Preferably, a pin is inserted into the inner wall of the sleeve, a bolt is fixedly connected to the top center of the pin, and the top of the bolt passes through the traction frame and is fixedly connected to a twist cap.

[0012] Preferably, the outer wall of the bolt is threaded with a fixing nut, and the side of the fixing nut away from the twist cap is fixedly connected to the outer wall of the traction frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model utilizes a sealing mechanism consisting of an air cylinder, piston, traction rod, friction ring, limit ring, and sealing ring. A vacuum pump, controlling a valve, draws air from the air chamber, causing a pressure difference between the two sides of the air cylinder to slide the piston, traction rod, traction frame, and mounting frame to the left. The mounting frame then causes the friction ring to slide synchronously and move against the outer wall of the limit ring. Simultaneously, the sealing ring is fixedly attached to the inner wall of the kiln head, achieving a sealing of the kiln head. This allows some parts of the device to move and press the friction ring against the limit ring, facilitating a movable seal of the kiln head and improving the stability and practicality of the device.

[0015] 2. This utility model utilizes a sleeve, pin, bolt, twist cap, and fixing nut in its assembly mechanism. By rotating the twist cap clockwise, the bolt is limited to a certain position. The bolt is restricted by the fixing nut, causing the bolt to slide downwards and insert into the inner wall of the sleeve, thus assembling the mounting frame. This allows some devices to assemble the mounting frame on the right side of the traction frame, facilitating the replacement of sealing components such as friction rings and improving the convenience and practicality of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 One embodiment provided by this utility model:

[0023] A novel sealing device for the kiln head of a dry process kiln includes a kiln cylinder 11, a kiln head 12 sleeved on the left side of the outer wall of the kiln cylinder 11, an air chamber 13 fixedly connected to the left side of the outer wall of the kiln head 12, a control air valve 14 fixedly connected to the front side of the outer wall of the air chamber 13, a vacuum pump 15 fixedly connected to the bottom of the control air valve 14, a traction frame 16 provided on the right side of the air chamber 13, and a mounting frame 17 attached to the right side of the traction frame 16.

[0024] A sealing mechanism 2 is provided on the right side of the air chamber 13. The sealing mechanism 2 includes an air cylinder 21. The left side of the air cylinder 21 is fixedly connected to the right side of the air chamber 13. A piston 22 is slidably connected to the inner wall of the air cylinder 21. A traction rod 23 is fixedly connected to the middle of the right side of the piston 22. The right end of the traction rod 23 passes through the air cylinder 21 and is fixedly connected to the left side of the traction frame 16. Through this design, the piston 22 drives the traction rod 23 and the traction frame 16 to slide left and right. The inner wall of the mounting frame 17 is fixedly connected to... Friction ring 24, with a limiting ring 25 attached to its inner wall. The inner wall of the limiting ring 25 is fixedly connected to the left side of the outer wall of the kiln cylinder 11. This design enables the mounting frame 17 to move and attach the friction ring 24 to the outer wall of the limiting ring 25. A sealing ring 26 is fixedly connected to the left side of the outer wall of the mounting frame 17. The outer wall of the sealing ring 26 is attached to the right side of the inner wall of the kiln head 12. This design achieves a seal between the outer wall of the mounting frame 17 and the inner wall of the kiln head 12.

[0025] The assembly frame 17 has an assembly mechanism 3 inside. The assembly mechanism 3 includes a sleeve 31. The left side of the outer wall of the sleeve 31 is fixedly connected to the right side of the assembly frame 17. A pin 32 is inserted into the inner wall of the sleeve 31. A bolt 33 is fixedly connected to the top center of the pin 32. The top of the bolt 33 passes through the traction frame 16 and is fixedly connected to a twist cap 34. Through this design, the twist cap 34 drives the bolt 33 and the pin 32 to rotate in a limited position. A fixing nut 35 is threadedly connected to the outer wall of the bolt 33. The side of the fixing nut 35 away from the twist cap 34 is fixedly connected to the outer wall of the traction frame 16. Through this design, the bolt 33 is restricted by the fixing nut 35 and drives the pin 32 to slide up and down, so that the sleeve 31 and the pin 32 can be assembled together to facilitate the replacement of the friction ring 24.

[0026] Working principle: When it is necessary to press seal the kiln head 12, the vacuum pump 15 is first started by power supply. The vacuum pump 15 draws air from the air chamber 13 by controlling the air valve 14, so that the air pressure difference on both sides of the air cylinder 21 drives the piston 22 to slide to the left. The piston 22 drives the traction frame 16 to slide synchronously through the traction rod 23. The traction frame 16 drives the mounting frame 17 and the friction ring 24 to slide synchronously, so that the friction ring 24 moves and fits against the outer wall of the limiting ring 25. At the same time, the sealing ring 26 is fixedly fitted against the inner wall of the kiln head 12, thus realizing the press seal operation of the kiln head 12.

[0027] When it is necessary to assemble the mounting bracket 17, first rotate the cover 34 clockwise. The cover 34 drives the bolt 33 to rotate in a limited position. The bolt 33 is restricted by the fixing nut 35, so that the bolt 33 drives the pin 32 to slide down and insert into the inner wall of the sleeve 31, thus realizing the assembly operation of the mounting bracket 17. The operation ends here.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
