Description
Technical Field
[0001] This utility model relates to the technical field of feeding devices, specifically a feeding device for desulfurized calcium powder silos. Background Technology
[0002] In industrial desulfurization processes, desulfurization calcium powder, such as calcium hydroxide powder and calcium carbonate powder, is a commonly used desulfurizing agent. It is usually stored in a powder silo and transported to the desulfurization system through a feeding device at the bottom of the silo when in use.
[0003] Existing powder silo discharging devices lack anti-sticking functionality in practical use. Desulfurization calcium powder has a certain degree of hygroscopicity and stickiness, easily adhering to the inner wall of the silo and causing sticking. Over time, the accumulated calcium powder thickens, reducing the effective storage volume of the silo and even causing blockages, thus affecting the normal operation of desulfurization. Currently, manual cleaning is typically performed at intervals, which is labor-intensive and poses safety hazards during equipment operation. Therefore, there is a need to develop a desulfurization calcium powder silo discharging device that can automatically clean the inner wall of the silo at intervals, eliminating the need for manual cleaning. Utility Model Content
[0004] To address the above technical problems, this utility model provides a desulfurization calcium powder silo feeding device that can automatically clean the inner wall of the powder silo at intervals without requiring manual cleaning, thus solving the problem that calcium powder easily adheres to the silo wall and requires manual cleaning in existing powder silos.
[0005] To solve the above-mentioned technical problems, the present invention provides a desulfurized calcium powder silo feeding device, comprising a silo tank body, an annular guide pipe fixedly connected to the top of the silo tank body, a plurality of equally spaced branch air pipes fixedly connected to the annular guide pipe, the lower end of each branch air pipe penetrating the top wall of the silo tank body and fixedly connected to a conical anti-clogging nozzle, a first solenoid valve fixedly connected to each branch air pipe, an air pump fixedly connected to the outside of the silo tank body, a conveying pipe fixedly connected to the outlet end of the air pump, the other end of the conveying pipe fixedly connected to the annular guide pipe, a conical hopper fixedly connected to the bottom of the silo tank body, an arc-shaped vibrating plate fixedly connected to the outer surface of the conical hopper body, and a vibration motor fixedly connected to the outer side of the arc-shaped vibrating plate.
[0006] Furthermore, a feed pipe is fixedly connected to the top of the powder silo tank, and a sealing cap is threadedly connected to the upper end of the feed pipe. A discharge pipe is fixedly connected to the bottom of the conical hopper, and a second solenoid valve is fixedly connected to the discharge pipe.
[0007] Furthermore, an intelligent controller is fixedly connected to the outer surface of the powder silo tank. The intelligent controller is electrically connected to the air pump, the vibration motor, the first solenoid valve, and the second solenoid valve via wires.
[0008] Furthermore, at least two support blocks are fixedly connected to the outer surface of the annular guide tube, and the bottom surface of each support block is fixedly connected to the top of the powder silo tank. Fixing blocks are fixedly connected to both the left and right sides of the intelligent controller, and the back of each fixing block is fixedly connected to the outer surface of the powder silo tank. A reinforcing block is fixedly connected to the outer surface of the air pump, and the right side of the reinforcing block is fixedly connected to the outer surface of the powder silo tank.
[0009] Furthermore, flange rings are fixedly connected to the outer surfaces of both the powder silo and the conical hopper, and the two flange rings are connected by fixing bolts.
[0010] This utility model has the following advantages compared with the prior art:
[0011] This invention utilizes a jetting structure comprised of an air pump, an annular guide pipe, branch air pipes, and a conical anti-clogging nozzle. This structure sprays airflow onto the inner wall of the powder silo, directly impacting the desulfurization calcium powder adsorbed on the wall surface. This disrupts the adhesion between the calcium powder and the silo wall, preventing the calcium powder from continuously sticking to the wall due to moisture absorption and stickiness. Simultaneously, the conical hopper is equipped with an arc-shaped vibrating plate and a vibrating motor, transmitting vibration energy to the inner wall of the hopper to further dislodge the adhering calcium powder. This dual action thoroughly solves the problems of wall adhesion and material blockage, ensuring the continuous and stable operation of the desulfurization system, reducing calcium powder accumulation on the wall, preventing the effective storage volume of the powder silo from being occupied, and ensuring that the powder silo always has sufficient usable space, thus improving storage efficiency. At the same time, the dislodged and blown-off calcium powder can participate in the normal feeding and conveying process, reducing material waste and lowering the material cost of the desulfurization process.

[0017] The present invention will be further described below with reference to the accompanying drawings.
[0018] like Figure 1-4 The device shown is a desulfurization calcium powder silo feeding device, including a silo tank 1. A feed pipe 12 is fixedly connected to the top of the silo tank 1. A sealing cap 13 is threaded onto the outer surface of the feed pipe 12. The feed pipe 12 provides a dedicated channel for the addition of desulfurization calcium powder, clearly defining the feeding position and ensuring that the calcium powder can accurately and smoothly enter the silo tank 1, preventing dust leakage or material spillage during the feeding process. The sealing cap 13 is tightly fitted to the feed pipe 12 via a threaded connection, effectively sealing the top opening of the silo tank 1 and preventing moisture from the outside air from entering the silo. To prevent calcium powder from absorbing moisture and clumping, increasing its stickiness, and to prevent dust from escaping from the silo, thus reducing dust pollution and ensuring a clean working environment, an annular guide pipe 2 is fixedly connected to the top of the powder silo tank 1. Multiple equally spaced branch air pipes 3 are fixedly connected to the lower surface of the annular guide pipe 2. The bottom end of each branch air pipe 3 penetrates the powder silo tank 1 and is fixedly connected to a conical anti-clogging nozzle 4. A first solenoid valve 5 is fixedly connected to each branch air pipe 3. An air pump 6 is fixedly connected to the outer surface of the powder silo tank 1. The outlet end of the air pump 6 is fixedly connected to a conveying pipe 7. 7. The other end is fixedly connected to the outer surface of the annular guide pipe 2. A conical hopper 9 is provided below the powder silo tank 1. Flange rings 16 are fixedly connected to the outer surfaces of both the powder silo tank 1 and the conical hopper 9. The two flange rings 16 are connected to a common threaded fixing bolt 17. The fixing bolt 17 is used to tighten the connection between the two, achieving a detachable and sealed connection, ensuring the sealing of the connection between the powder silo tank 1 and the conical hopper 9, preventing calcium powder from leaking from the gaps during the falling process, and reducing material loss and dust pollution; the outer surface of the conical hopper 9 is fixed An arc-shaped vibrating plate 10 is connected, and a vibrating motor 11 is fixedly connected to the outer surface of the arc-shaped vibrating plate 10 by bolts; the bottom end of the conical hopper 9 is fixedly connected to a discharge pipe 18, and the outer surface of the discharge pipe 18 is fixedly connected to a second solenoid valve 19. The discharge pipe 18 is fixedly connected to the bottom end of the conical hopper 9, providing a dedicated channel for the output of desulfurized calcium powder in the silo, guiding the calcium powder to be accurately delivered to the desulfurization system, ensuring a clear and smooth discharge path. The second solenoid valve 19 is installed on the outer surface of the discharge pipe 18, which can accurately control the opening and closing of the discharge pipe 18 and the discharge flow rate.
[0019] A smart controller 8 is fixedly connected to the outer surface of the powder silo tank 1. Fixing blocks 15 are fixedly connected to both the left and right sides of the smart controller 8. The back of each fixing block 15 is fixedly connected to the outer surface of the powder silo tank 1. The fixing blocks 15 are symmetrically arranged on the left and right sides of the smart controller 8 and fixedly connected to the outer surface of the powder silo tank 1, providing a solid installation foundation for the smart controller 8 and ensuring that the smart controller 8 is stably fixed on the powder silo tank 1. This prevents the smart controller 8 from loosening, shifting or falling off due to vibration during equipment operation, and ensures the safety of its internal circuits and control components. The smart controller 8 is electrically connected to the air pump 6, the vibration motor 11, the first solenoid valve 5 and the second solenoid valve 19 through wires.
[0020] Two support blocks 14 are fixedly connected to the outer surface of the annular guide pipe 2. The bottom surface of each support block 14 is fixedly connected to the top of the powder silo tank 1. The support blocks 14 are fixedly connected between the outer surface of the annular guide pipe 2 and the top of the powder silo tank 1, providing stable support and fixing for the annular guide pipe 2. This prevents the annular guide pipe 2 from shifting or deforming due to airflow impact or its own weight during the ventilation process, ensures the sealing of the connection between the annular guide pipe 2 and the branch air pipe 3, prevents airflow leakage, ensures the stable operation of the jet anti-sticking function, and at the same time disperses the force on the annular guide pipe 2, extending its service life. A reinforcing block 20 is fixedly connected to the outer surface of the air pump 6. The right side of the reinforcing block 20 is fixedly connected to the outer surface of the powder silo tank 1. The reinforcing block 20 provides stable installation and fixing support for the air pump 6, ensuring the stability of the air pump 6 during use and preventing the air pump 6 from shaking during operation.
[0021] The working principle of this embodiment is as follows:
[0022] During use, unscrew the sealing cap 13 on the outer surface of the feed pipe 12, and add an appropriate amount of desulfurization calcium powder into the powder silo tank 1 through the feed pipe 12. After adding the material, tighten the sealing cap 13 to ensure that the powder silo tank 1 is sealed to prevent external moisture from entering and dust from leaking out. The powder silo tank 1 is treated intermittently according to the operation of the desulfurization system. The intelligent controller 8 issues a start command, and the air pump 6 starts to generate high-pressure airflow, which is delivered to the annular guide pipe 2 via the conveying pipe 7. The annular guide pipe 2 evenly distributes the high-pressure airflow to multiple equally spaced branch air pipes 3. At the same time, it controls the first solenoid valve 5 to open, and the airflow is delivered to the conical anti-clogging nozzle 4 via the branch air pipe 3. The conical anti-clogging nozzle 4 penetrates the powder silo tank 1 and faces the silo wall, spraying the high-pressure airflow onto the inner wall of the powder silo tank 1, impacting the calcium powder adsorbed on the wall surface, causing it to detach from the silo wall and fall. While the air pump 6 is working, the intelligent controller 8... The controller 8 starts the vibration motor 11. The vibration energy generated by the vibration motor 11 is transmitted to the entire conical hopper 9 through the arc-shaped vibration plate 10, shaking off the calcium powder adhering to the inner wall of the conical hopper 9 and promoting the flow of calcium powder in the hopper, thus preventing the accumulation and blockage at the bottom of the hopper. Under the action of gravity, airflow impact and vibration, the calcium powder in the powder silo tank 1 falls smoothly into the conical hopper 9. According to the calcium powder demand of the desulfurization system, the intelligent controller 8 controls the second solenoid valve 19 to open. The calcium powder is accurately delivered to the desulfurization system through the discharge pipe 18. By adjusting the opening of the second solenoid valve 19, the discharge flow rate can be controlled to ensure that it matches the needs of the desulfurization system. During the operation of the desulfurization system, the device can continuously prevent calcium powder from sticking to the wall and blocking the material. If maintenance or cleaning is required, the fixing bolts 17 on the flange ring 16 can be removed to separate the powder silo tank 1 from the conical hopper 9 for subsequent maintenance operations.
