Description

Technical Field

[0001] This utility model relates to the field of polyferric sulfate feeding technology, specifically to a feeding device for the production of polyferric sulfate. Background Technology

[0002] Polyferric sulfate (PFS) is a high-performance inorganic polymeric flocculant. It is a pale yellow, amorphous powder, readily soluble in water; a 10% (by mass) aqueous solution is a reddish-brown, transparent solution. It is hygroscopic. PFS is widely used in the purification of drinking water, industrial water, various industrial wastewaters, municipal sewage, and sludge dewatering. The preparation of PFS mainly involves direct oxidation and catalytic oxidation. Most PFS are prepared using the direct oxidation method, which has a simpler process route and can reduce equipment investment and production steps, thus lowering equipment costs in industrial production. However, this process relies on an oxidant, such as inorganic oxidants like H₂O₂, KClO₃, or HNO₃. Catalytic oxidation generally uses a catalyst to oxidize PFS using oxygen or air.

[0003] The production of polyferric sulfate requires a large amount of raw materials. If the grab bucket of a forklift is used to transport the materials, it can only grab once at a time, and may grab lumps of polyferric sulfate, which will affect the quality of subsequent processing and cause raw material pollution and waste. Utility Model Content

[0004] This invention aims to solve the above-mentioned technical problems by providing a feeding device for the production of polyferric sulfate.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A feeding device for producing polyferric sulfate includes a conveyor belt, with supports installed on both sides of the conveyor belt, and a hopper connected between the two supports. The outlet of the hopper is located directly above the conveyor belt.

[0007] One side of the support is equipped with an alternating feeding device for receiving materials on the conveyor belt.

A screw mechanism for driving the movable plates is respectively installed on one side of the mounting frame.

[0009] Preferably, the lead screw mechanism includes a drive motor and a lead screw at the output end of the drive motor. The lead screw is mounted in a mounting frame via bearings. Both mounting frames are equipped with ball nuts that work with the lead screw.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0024] The present invention will now be described in further detail in conjunction with the full text.

[0025] Combined with appendix Figures 1-3 A feeding device for producing polyferric sulfate includes a conveyor belt 1, supports 2 installed on both sides of the conveyor belt 1, a hopper 3 connected between the two supports 2, and the outlet of the hopper 3 located directly above the conveyor belt 1; a staggered feeding device 4 for receiving materials on the conveyor belt 1 is installed on one side of the supports 2.

[0026] In specific implementation of this utility model, such as Figure 2 and Figure 3 As shown, the staggered dispensing device 4 includes a mounting frame 401 connecting the support bracket 2. Movable plates 402 are mounted opposite each other on the mounting frame 401. Feed hoppers 403 are fixedly connected to the lower ends of the two movable plates 402, and the two feed hoppers 403 can form a storage area for materials. Screw mechanisms for driving the movable plates 402 are respectively mounted on one side of the mounting frame 401. The screw mechanisms can drive the feed hoppers 403 to move.

[0027] In specific implementation of this utility model, such as Figure 2 and Figure 3As shown, the screw mechanism includes a drive motor 406 and a screw 404 at the output end of the drive motor 406. The screw 404 is mounted in a mounting bracket 401 via bearings. Both mounting brackets 401 are equipped with ball nuts 405 that work with the screw 404. Specifically, the ball nuts 405 and the screw 404 of the screw mechanism are either self-locking ball screws or trapezoidal screws. The lower ends of the two ball nuts 405 are respectively connected to two moving plates 402, which can drive two feeding hoppers 403 to feed materials alternately. The two drive motors 406 rotate via the screw 404, causing the ball nuts 405 to move and the two feeding hoppers 403 to move closer to the conveyor belt 1. When they reach the closest position, the two feeding hoppers 403 merge together, forming a storage area for materials. Rubber buffer layers are installed on the opposite surfaces of the two feeding hoppers 403 to ensure a more reliable and sealed storage area between them. After the raw materials enter the storage area, both drive motors 406 operate simultaneously, thereby driving both feeding hoppers 403 to move simultaneously. This ensures that the materials in the storage area are fully loaded and reach the appropriate position. Once the material reaches the desired position, one drive motor 406 stops operating, while the other continues operating, allowing one feeding hopper 403 to move and thus stagger the feeding of raw materials by the two feeding hoppers 403. The feed inlets for the processing equipment housing used in the production of polyferric sulfate are installed directly below the staggered feeding positions of the two feeding hoppers 403.

[0028] In specific implementation of this utility model, such as Figure 1 and Figure 2 As shown, guide plates 5 are fixedly connected to both sides of the outlet of hopper 3. A rubber shovel 6 is installed between the two guide plates 5 and at the outlet of hopper 3. The two guide plates 5 can guide the raw materials, and the guide plates 5 are close to the conveyor belt 1, which can transport the raw materials normally. The rubber shovel 6 can block large pieces of raw materials and can spread the raw materials out to prevent them from falling.

[0029] A guide plate 7 inclined towards the feeding hopper 403 is installed between the two mounting brackets 401. The guide plate 7 serves to guide the material, and one side of the guide plate 7 is close to the conveyor belt 1 to scrape the raw material on the conveyor belt 1 and convey it into the storage area in a good way.

[0030] The working principle of this utility model:

[0031] Raw materials are placed into hopper 3. Two drive motors 406 rotate via lead screw 404, driving ball nuts 405 to move, which in turn moves two feeding hoppers 403 closer to conveyor belt 1. When they reach the closest position, the two feeding hoppers 403 merge together, forming a storage area for materials. Raw materials are waiting to enter the storage area. Conveyor belt 1 moves, and the outlet of hopper 3 can be transported to the storage area via conveyor belt 1. After the materials are stored in the storage area, conveyor belt 1 stops working, and the two drive motors 406 work simultaneously, thereby driving the two feeding hoppers 403 to move simultaneously, ensuring that the materials in the storage area are completely stored. After reaching the appropriate position, one drive motor 406 stops working, while the other continues to work, allowing one feeding hopper 403 to move and completing the staggered feeding of raw materials by the two feeding hoppers 403.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
