Description

Technical Field

[0001] This utility model relates to the technical field of hot blast stove feeding equipment, specifically a rice husk feeding device for hot blast stoves. Background Technology

[0002] When rice husks are used as fuel in a hot blast stove, they need to be fed into the stove in an orderly manner through a feeding device. Rice husks are large in volume, and the feeding speed using a screw feeder is slow, which is difficult to meet the combustion requirements of the hot blast stove. If pneumatic conveying is used, the rice husks are easy to clog, which will lead to interruption of the feeding. Therefore, a feeding device that can quickly convey rice husks and is not easy to clog is needed. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a rice husk feeding device that uses both wind power and a pusher plate to push materials, with the rotating shaft linked with the stirring and pushing components to prevent material blockage, thereby solving the problems mentioned in the background art.

[0004] The technical problem solved by this utility model is achieved by the following technical solution: a rice husk feeding device for a hot blast stove, including a feeding pipe, a feeding hopper disposed on one side of the feeding pipe, and a discharge cylinder disposed on the side of the feeding pipe away from the feeding hopper. The end of the feeding pipe near the feeding hopper is connected to an air inlet pipe. An air pressure plate is inclinedly disposed at the lower end of the feeding pipe at the feeding hopper to prevent air from being blown into the feeding hopper. An opening is provided between the lower end of the feeding hopper away from the air inlet pipe and the air pressure plate to guide the material into the feeding pipe.

[0005] The feeding pipe is equipped with a rotating component to prevent material blockage, the feeding hopper is equipped with a stirring component that is linked to the rotating component, and the discharging cylinder is equipped with a pushing component that is linked to the rotating component, so as to prevent the rice husks in the feeding pipe, feeding hopper and discharging cylinder from being blocked, thereby achieving stable conveying of rice husks.

[0006] The air inlet pipe is inclinedly arranged on the outside of the feeding pipe, and two sets are symmetrically arranged. The air inlet pipe is connected to the fan to blow air into the feeding pipe to transport materials.

[0007] The rotating component includes a rotating shaft rotatably installed inside the feeding pipe and pusher plates distributed on the outer end of the rotating shaft. The pusher plates are inclined and fixedly connected to the rotating shaft through a support plate to push the material in the feeding pipe forward and prevent material blockage.

[0008] A frame plate is provided on one side of the outer end of the feeding pipe, and a rotary motor is installed on the outer end of the frame plate. The rotating shaft passes through the bearing corresponding to the feeding pipe and is connected to the rotary motor for transmission. A first sprocket is fixedly installed between the frame plate and the feeding pipe on the rotating shaft so as to connect with the stirring component through the first sprocket.

[0009] The agitator includes an agitator shaft rotatably mounted in the feed hopper and agitator rods distributed on the agitator shaft to push the material in the feed hopper downwards and prevent material blockage. The outer end of the agitator shaft passes through the bearing corresponding to the feed hopper. A second sprocket is fixedly mounted on the agitator shaft corresponding to the first sprocket. The first sprocket and the second sprocket are connected by chain drive to realize synchronous rotation of the agitator shaft and the rotating shaft. The feed pipe is provided with a support frame corresponding to the agitator shaft to provide stability to the agitator shaft.

[0010] As a further embodiment of this utility model:

[0011] The pusher includes a vertically arranged shaft. A sliding sleeve is provided on the inner wall of the upper end of the feed cylinder corresponding to the shaft. The shaft is slidably connected in the sliding sleeve. The shaft is irregularly shaped to restrict the rotation of the shaft through the sliding sleeve. A bottom plate is provided on the inner wall of the lower end of the feed cylinder to restrict the downward movement of the shaft. A lifting plate is provided at the upper end of the shaft. A lever is provided at the corresponding position of the rotating shaft to push the lifting plate to move. When the rotating shaft rotates clockwise, the lever drives the lifting plate to rise, and the shaft descends under its own weight. Several push rods are distributed on the outer side of the lower end of the shaft to drive the material to move.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Air inlet pipes are provided on both sides of one end of the feeding pipe, and a fan is connected to the air inlet pipe to supply air into the feeding pipe. The introduced air is blocked by the air pressure plate to prevent air from being blown into the feeding hopper. Furthermore, the opening between the feeding hopper and the air pressure plate will generate negative pressure due to the rapidly flowing gas below, driving the material into the feeding pipe. The material in the feeding pipe moves forward rapidly under the combined action of the air blowing and the pusher plate. The pusher plate is driven by the rotation of the rotating shaft, which can prevent material blockage in the feeding pipe and accelerate material supply. The feeding hopper and the discharge cylinder are respectively equipped with components linked to the rotating shaft to prevent blockage in the feeding hopper and the discharge cylinder. The pusher component uses a lever on the rotating shaft to drive the lifting plate upwards at intervals, causing the shaft to move back and forth. The pusher rod agitates the material in the discharge cylinder, preventing material blockage. Attached Figure Description

[0023] A frame plate 14 is provided on one side of the outer end of the feeding pipe 1. A rotary motor 15 is installed on the outer end of the frame plate 14. The rotating shaft 12 passes through the bearing corresponding to the feeding pipe 1 and is connected to the rotary motor 15 for transmission. A first sprocket 17 is fixedly installed between the frame plate 14 and the feeding pipe 1 on the rotating shaft 12 so as to connect with the stirring component through the first sprocket 17.

[0024] In this embodiment, the agitator includes an agitator shaft 21 rotatably mounted in the feed hopper 2 and agitator rods 22 distributed on the agitator shaft 21 to push the material in the feed hopper 2 down and avoid material blockage. The outer end of the agitator shaft 21 passes through the bearing corresponding to the feed hopper 2. A second sprocket 23 is fixedly mounted on the agitator shaft 21 corresponding to the first sprocket 17. The first sprocket 17 and the second sprocket 23 are connected by a chain 24 to realize that the agitator shaft 21 rotates synchronously with the rotating shaft 12.
