[0024] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] Please refer to Figures 1-6 The intermediate silo feeding device for dry powder carbide slag includes a square silo 1, a conical silo 2 fixedly installed at the bottom of the square silo 1, several feeding pipes 5 installed at the bottom of the conical silo 2, an inclined plate 8 fixedly installed inside the conical silo 2, flow aid components installed on the side of the conical silo 2 and on the inclined plate 8, and a blowing component installed at the bottom of the inclined plate 8.

[0026] In a specific embodiment of this utility model, the square bin 1 and the conical bin 2 are mainly used as intermediate bins. Their main function is to regulate material pressure and flow rate, and to buffer or cache materials. That is, the material is transported from the storage bin (or transport vehicle) to the intermediate bin through a special conveying device, and then from the intermediate bin to the equipment of the next process. In this solution, the material is fed in from the top inlet of the square bin 1, then falls into the conical bin 2, and then is distributed to the equipment of the next process from the conical bin 2. The flow aid component is mainly used to fluidize the material, that is, to transform the dry powder material from a piled state to a fluid-like state through a uniformly permeating airflow, thereby breaking up agglomerates, reducing material friction, ensuring smooth unloading, and avoiding the problem of material accumulation in the intermediate bin causing discharge blockage. The blowing component can be used to blow the bottom of the conical bin 2 to prevent material from falling onto the inner bottom surface of the conical bin 2, thereby preventing the problem of material slowly remaining on the inner bottom surface of the conical bin 2 and causing a large amount of accumulation. In this solution, there are three discharge pipes 5, and their specific arrangement is shown in the appendix. Figure 1 .

[0027] The bottom end of the feeding pipe 5 is equipped with a control component for controlling the opening and closing of the feeding pipe 5. Each feeding pipe 5 corresponds to an independent control component. The control component can be used to control feeding or stop feeding, thereby achieving the effect of controlling the feeding flow rate.

[0028] The control components include a star feeder 6, the inlet of which is fixedly connected to the bottom end of the discharge pipe 5, and the outlet of which is connected to the equipment of the next process. It can be connected to the equipment of the next process through a conveying pipeline or a trough. For example, the inlet of the conveying pipeline is connected to the outlet of the star feeder 6, and the outlet of the conveying pipeline is connected to the equipment of the next process.

[0029] Specifically, the star feeder 6 can be an existing conventional device, which can be driven by a servo motor. When the servo motor starts, it can drive the star-shaped plate inside the star feeder 6 to rotate. When the plate rotates, it can realize the output of materials. When the plate stops rotating, it stops the output of materials. By changing the speed of the servo motor, the output rate of materials can be adjusted.

[0030] Two inclined plates 8 are symmetrically arranged, and their bottom ends are fixedly connected to the inner bottom surface of the conical chamber 2, their top ends are fixedly connected to the inner front wall and inner rear wall of the conical chamber 2 respectively, and their two sides are fixedly connected to the two side walls of the conical chamber 2 respectively.

[0031] Specifically, the bottom ends of the two inclined plates 8 are close to each other but do not touch, and the bottom ends of the two inclined plates 8 are located on the front and rear sides of the feed pipe 5, respectively. That is, the connection between the feed pipe 5 and the conical bin 2 is located between the bottom ends of the two inclined plates 8. This arrangement can minimize the area of ​​the inner bottom surface of the conical bin 2, so that the inlet of the feed pipe 5 occupies most of the area of ​​the inner bottom surface of the conical bin 2, thereby reducing the probability of material falling on the inner bottom surface of the conical bin 2 and reducing the risk of accumulation.

[0032] The flow aid assembly includes an aeration plate 7, an inclined plate 8, and aeration plates 7 on both sides of the conical chamber 2. The air outlets of the aeration plates 7 are all located inside the conical chamber 2. The aeration plates 7 are existing conventional equipment, which provides a stable airflow inside the conical chamber 2, so that the material falls in a flowing manner, thereby reducing the accumulation of material and avoiding material bridging or blockage.

[0033] The blowing assembly includes a blower 10, which is fixedly installed at the bottom end of the inclined plate 8. The bottom end of the inclined plate 8 has a vent 9. The blower 10 can blow air onto the inner bottom surface of the conical bin 2, thereby cleaning the inner bottom surface of the conical bin 2 and preventing material from accumulating on the inner bottom surface of the conical bin 2. In use, the air blows out from inside the blower 10 and passes through the vent 9 to clean the inner bottom surface of the conical bin 2.

[0034] Both the air duct 10 and the aeration plate 7 are supplied with air through an air supply assembly. The air duct 10 and the aeration plate 7 are connected to the air supply assembly through pipelines. The air supply assembly can use existing conventional equipment for air supply, such as a Roots blower. The air generated by the Roots blower is delivered to the aeration plate 7 and the air duct 10 through pipelines to achieve the air supply effect for the air duct 10 and the aeration plate 7. The specific setup is as follows: the pipeline consists of a main pipeline and branch pipelines. The inlet of the main pipeline is connected to the outlet of the Roots blower. The outlet of the main pipeline is equipped with a multi-way connector (or a distributor). One end of each branch pipeline is connected to the multi-way connector, and the other end is connected to the corresponding air duct 10 or aeration plate 7.

[0035] A filter screen 11 is fixedly installed on the air duct 10 near the air hole 9. The filter screen 11 can prevent materials from entering the air duct 10.

[0036] The conical chamber 2 is provided with a cover plate 3 and a fixing plate 4 at both the front and rear. The cover plate 3 and the fixing plate 4 are detachably connected to the conical chamber 2 and can be detachably connected by screws. The cover plate 3 can be used to close the corresponding gasification plate 7. The fixing plate 4 can be used to close the corresponding air duct 10.

[0037] Workflow: During the production process, when materials are delivered to various processing equipment, they are first transported from the storage silo to the intermediate silo. The intermediate silo then acts as a buffer or buffer to adjust the flow rate of the material output and distribute it to the equipment in the next process. Specifically, the material in the storage silo is transported to the square silo 1 (pneumatic conveying, enclosed belt conveyor, or bucket elevator can be used for feeding to avoid dust spillage). The material then falls into the conical silo 2. During this process, the air supply component is activated to provide a stable airflow to the conical silo 2 through the aeration plate 7, fluidizing the material and preventing it from accumulating, bridging, or blocking within the conical silo 2. The material continues to fall into the discharge pipe 5 and is then fed by the star feeder 6, which can control the discharge flow rate. When the material falls to the bottom of the conical silo 2, the blowing component prevents the material from accumulating on the bottom surface of the conical silo 2, reducing the risk of blockage.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
