Description

Technical Field

[0001] This utility model relates to the field of cement production equipment technology, and more specifically, to a blower-driven inclined material layer blowing device. Background Technology

[0002] The grate cooler is an important main equipment in the clinker calcination system of a cement plant. Its main functions are to cool and transport cement clinker; at the same time, it provides hot air for rotary kilns and decomposition furnaces, and is the main equipment for heat recovery in the calcination system. During production, hot cement clinker can be unloaded from the kiln opening onto the fixed plate in the grate cooler hopper, forming a material layer of a certain thickness.

[0003] A search revealed a Chinese patent publication (CN 204854372 U) that discloses a grate cooler hopper. While this method uses two air cannons installed parallel to each other on the side wall of the hopper to disperse the fixed plate material layer accumulated within it, the fixed positions of the two air cannons limit the dispersion area of ​​the fixed plate material layer. This results in an uneven distribution of the material layer across the entire fixed bed, affecting the dispersion and blowing effect. Therefore, this invention designs a blower-driven oblique-blowing material layer blowing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a blower-driven oblique blowing material layer blowing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A blower-driven inclined material layer blowing device includes a grate cooler hopper and a side sealing frame. The grate cooler hopper has two symmetrical openings I on its side. The side sealing frame is fixedly installed on the outside of the grate cooler hopper. The side of the side sealing frame has an opening II at a position corresponding to the opening I. The side sealing frame has a limiting groove that connects to the opening II. Two sealing plates for sealing the opening II are symmetrically slidably connected in the limiting groove. A side seat is fixedly installed on the outside of the sealing plate. A blowing component is provided on the side seat. The side sealing frame is provided with a drive component for driving the two blowing components to reciprocate.

[0007] As a preferred embodiment of this utility model, the blowing assembly includes a blower and an inclined blowing pipe. The blower is fixedly installed on the side seat, and the inclined blowing pipe is fixedly connected to the air outlet of the blower. The inclined blowing pipe passes through the side of the sealing plate.

[0008] As a preferred technical solution of this utility model, the inclined blowing pipe includes an air guide pipe and an air nozzle, and the air nozzle is inclined and fixedly connected to the end of the air guide pipe.

[0009] As a preferred embodiment of this utility model, the drive assembly includes a motor and a bidirectional screw. The motor is fixedly installed on the outside of the side sealing frame, and the bidirectional screw is fixedly connected to the drive end of the motor. The two side seats are respectively threaded onto the forward and reverse threaded portions of the bidirectional screw.

[0010] As a preferred embodiment of this utility model, a bearing seat is fixedly installed on the side sealing frame, and the bearing seat is rotatably connected to one end of the bidirectional screw.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes the airflow generated by the blower during operation, which is sequentially discharged through the air duct and the nozzle. This disperses the fixed plate material layer in the grate cooler hopper. The forward rotation of the bidirectional screw driven by the motor causes the two side seats to move closer to each other, while the reverse rotation of the bidirectional screw causes the two side seats to move further apart. The sealing plate sliding along the limiting groove always seals the opening II, thereby driving the two blowing components to move back and forth. This effectively expands the dispersion area of ​​the fixed plate material layer in the grate cooler hopper, making the material layer distribution in the entire fixed bed more uniform and improving the dispersion and blowing effect of the fixed plate material layer in the grate cooler hopper.

[0018] 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.

[0019] like Figures 1 to 4 As shown, this utility model provides a blower-driven inclined material layer blowing device, including a grate cooler hopper 1 and a side sealing frame 2. The grate cooler hopper 1 has two symmetrical openings I101 on its side. The side sealing frame 2 is fixedly installed on the outside of the grate cooler hopper 1. The side of the side sealing frame 2 has an opening II201 at the position corresponding to the opening I101. The side sealing frame 2 has a limiting groove 202 connected to the opening II201. Two sealing plates 3 for sealing the opening II201 are symmetrically slidably connected in the limiting groove 202. A side seat 4 is fixedly installed on the outside of the sealing plate 3. A blowing component 5 is provided on the side seat 4. The side sealing frame 2 is provided with a driving component 6 for driving the two blowing components 5 to reciprocate.

[0020] Among them, such as Figure 1 and Figure 2 As shown, the blowing assembly 5 includes a blower 501 and an oblique blowing pipe 502. The blower 501 is fixedly installed on the side seat 4, and the oblique blowing pipe 502 is fixedly connected to the air outlet of the blower 501. The oblique blowing pipe 502 passes through the side of the sealing plate 3.

[0021] Among them, such as Figure 2 As shown, the inclined blowing pipe 502 includes an air guide pipe 503 and a blower nozzle 504. The blower nozzle 504 is inclined and fixedly connected to the end of the air guide pipe 503. The airflow generated by the blower 501 during operation can be discharged sequentially through the air guide pipe 503 and the blower nozzle 504.

[0022] Among them, such as Figure 2 As shown, the drive assembly 6 includes a motor 601 and a bidirectional screw 602. The motor 601 is fixedly installed on the outside of the side sealing frame 2, and the bidirectional screw 602 is fixedly connected to the drive end of the motor 601. The two side seats 4 are respectively threaded onto the forward and reverse threaded portions of the bidirectional screw 602.

[0023] Among them, such as Figure 4 As shown, a bearing seat 7 is fixedly installed on the side sealing frame 2. The bearing seat 7 is rotatably connected to one end of the bidirectional screw 602, which achieves the purpose of ensuring the rotational stability of the bidirectional screw 602.

[0024] The working principle of this utility model:

[0025] The airflow generated by the blower 501 during operation can be discharged sequentially through the air duct 503 and the blower nozzle 504, which can disperse the fixed plate material layer in the grate cooler hopper 1. The bidirectional screw 602 driven by the motor 601 rotates in the forward direction, which can make the two side seats 4 move closer to each other. The bidirectional screw 602 rotates in the reverse direction, which can make the two side seats 4 move further away from each other. The sealing plate 3 sliding along the limiting slide groove 202 always seals the opening II 201, thereby driving the two blowing components 5 to move back and forth, effectively expanding the dispersion area of ​​the fixed plate material layer in the grate cooler hopper, making the material layer distribution of the entire fixed bed more uniform.
