AI Technical Summary
Existing fluidization devices are prone to material suspension or blockage during the discharge of powder materials, resulting in uneven material flow, affecting the smoothness of quicklime material falling, and even causing blockage of the discharge hopper.
By forming an air film on the inner wall of the hopper, a high-pressure airflow is input by an air pump and combined with a drive mechanism to drive the fluidizer to rotate, so that the air film rotates around the material, enhancing the material's fluidity and preventing the material from adhering to the hopper. The inverted conical structure and sealed connection reduce the risk of blockage.
It effectively prevents hopper blockage, ensures smooth material flow, improves fluidity, avoids material adhesion in the hopper, and ensures stable descent of quicklime.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of hopper fluidization devices, and in particular to a silo fluidization device for a batching room. Background Technology
[0002] During operation, the quicklime silo in the batching room frequently experiences quicklime suspension or blockage, preventing the material from falling smoothly and resulting in uneven and unsmooth quicklime flow. This situation severely impacts the stability of the moisture content and sintering alkalinity of the mixed material.
[0003] A fluidizer is a flow aid element in the discharge process of powdered materials, mainly used in powdered material storage and blast furnace pulverized coal injection systems. This device introduces air into the lower part of the hopper, which then fluidizes the powder through a perforated plate, enhancing its flowability and preventing bridging and agglomeration, thus ensuring smooth material discharge.
[0004] Existing fluidizing devices are usually fixed directly to the lower end of the hopper. However, the intensity of the airflow blown out by the fluidizer gradually decreases as the distance from the fluidizer increases, resulting in uneven airflow intensity in the hopper. In some cases, the hopper may not even be covered by the air film, causing quicklime to adhere to the hopper and leading to problems such as bridging and difficulty in feeding, or even clogging of the hopper. Utility Model Content
[0005] This utility model addresses the shortcomings of existing technologies by providing a fluidizing device for a batching chamber. An air film is formed on the inner wall of the hopper through an airflow channel and a fluidizer. The hopper drives the fluidizer to rotate, causing the air film to rotate around the material flowing out of the batching chamber, making it difficult for the material to adhere to the hopper and preventing clogging.
[0006] This utility model is achieved through the following technical solution: a fluidizing device for a batching chamber is provided, comprising a hopper disposed at the bottom of the batching chamber and connected to the batching chamber, an air guide pipe being provided outside the hopper, forming an airflow channel between the air guide pipe and the hopper; a fluidizer connected to the airflow channel is provided inside the hopper, and an air pump is connected to the airflow channel; a drive mechanism for driving the hopper to rotate is provided on the batching chamber; the air pump inputs high-pressure airflow into the hopper through the airflow channel and the fluidizer, forming an air film on the inner wall of the hopper; the drive mechanism drives the fluidizer to rotate through the hopper, thereby causing the air film to rotate around the material flowing out of the batching chamber, thus making it difficult for the material to adhere to the hopper and preventing clogging of the hopper.
[0007] As an optimization, the batching chamber is sealed to the discharge hopper via a sealing ring; the sealing ring reduces the possibility of material passing between the batching chamber and the discharge hopper.
[0008] As an optimization, the bottom of the batching chamber extends downward into the inner ring of the sealing ring, and the bottom of the sealing ring extends downward into the discharge hopper; the batching chamber, sealing ring, and discharge hopper cover each other in sequence, reducing the possibility of material passing through the batching chamber, sealing ring, and discharge hopper.
[0009] As an optimization, the hopper is sealed with a sealing ring and an air guide pipe; the sealing ring prevents air from flowing out of the airflow channel, thereby preventing insufficient air pressure output by the fluidizer.
[0010] As an optimization, the hopper has an inverted cone shape; the inverted cone shape of the hopper avoids violent agitation of the material inside the hopper.
[0011] The beneficial effects of this utility model are as follows: the air pump inputs high-pressure airflow into the hopper through the airflow channel and fluidizer and forms an air film on the inner wall of the hopper. The drive mechanism drives the fluidizer to rotate through the hopper, so that the air film rotates around the material flowing out of the batching chamber, making it difficult for the material to adhere to the hopper and avoiding clogging of the hopper.

Detailed Implementation
[0013] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0014] like Figure 1 The fluidized bed device for the batching chamber of this utility model includes a hopper 2 mounted on the bottom of the batching chamber 1 and connected to the batching chamber 1. An air guide pipe 3 is fitted over the hopper 2, forming an airflow channel between the air guide pipe 3 and the hopper 2. A fluidizer 4, connected to the airflow channel, is installed inside the hopper 2. An air pump 5 is connected to the airflow channel. A drive mechanism 6, which drives the hopper 2 to rotate, is installed on the batching chamber 1. The fluidizer 4 and air pump 5 are existing technologies. The drive mechanism 6 includes a driven gear 601 coaxially fixed to the hopper 2. The driven gear 601 meshes with a driving gear 602, which is mounted on the batching chamber 1. A motor 603, which drives the driving gear 602 to rotate, is fixed on the batching chamber 1. The air guide pipe 3 is fixed to the batching chamber 1. A discharge port, equipped with a valve 7, is located at the bottom of the hopper 2.
[0015] Turn on the air pump 5, which inputs high-pressure air into the airflow channel. The high-pressure air in the airflow channel enters the hopper 2 through the fluidizer 4 and forms an air film on the inner wall of the hopper 2. Start the drive mechanism 6, which drives the hopper 2 to rotate on the batching chamber 1 and the air guide pipe 3. The hopper 2 drives the fluidizer 4 to rotate. The air film formed by the fluidizer 4 rotates around the material flowing out of the batching chamber 1, which enhances the fluidity of the material and allows it to flow out through the outlet of the hopper 2.
[0016] like Figure 1 and Figure 2 The batching chamber 1 shown is sealed and connected to the feed hopper 2 by a sealing ring 8.
[0017] The sealing ring 8 seals the gap between the batching chamber 1 and the discharge hopper 2.
[0018] like Figure 1 and Figure 2 The bottom of the batching chamber 1 extends downward into the inner ring of the sealing ring 8, and the bottom of the sealing ring 8 extends downward into the feeding hopper 2.
[0019] The material in the batching chamber 1 passes through the sealing ring 8 and enters the feeding hopper 2.
[0020] like Figure 1 The feed hopper 2 shown is sealed and connected by a sealing ring 9 and an air guide pipe 3.
[0021] The sealing ring 9 seals the gap between the feed hopper 2 and the air guide pipe 3.
[0022] like Figure 1 The feed hopper 2 shown is an inverted cone shape.
[0023] The drive mechanism 6 drives the inverted cone-shaped hopper 2 to rotate, and the hopper 2 and the material inside the hopper 2 move relative to each other.
[0024] In actual production, the air pump 5 is turned on, and the air pump 5 inputs high-pressure air into the airflow channel. The high-pressure air in the airflow channel enters the feeding hopper 2 through the fluidizer 4 and forms an air film on the inner wall of the feeding hopper 2. The drive mechanism 6 is started, and the drive mechanism 6 drives the feeding hopper 2 to rotate on the batching chamber 1 and the air guide pipe 3. The feeding hopper 2 and the material in the feeding hopper 2 move relative to each other. The feeding hopper 2 drives the fluidizer 4 to rotate. The air film formed by the fluidizer 4 rotates around the material flowing out of the batching chamber 1. The material flowability is enhanced and it flows out through the outlet of the feeding hopper 2.
