[0001] This utility model relates to the field of mixing tank technology, and specifically to a mixing tank discharge device. Background technology:

[0002] Hydrogen fluoride (HF) is an important chemical raw material widely used in the chemical, electronics, and pharmaceutical industries. The production of hydrogen fluoride typically involves the production and refining of hydrofluoric acid, and the mixing, transportation, and handling of raw materials are crucial steps in this process.

[0003] In the traditional hydrogen fluoride production process, the discharge from the mixing tank is usually pumped or gravity conveyed, but this is prone to blockage. To solve the above problems, screw conveyors have been used for conveying. However, the connection between the screw conveyor and the mixing tank is mostly fixed, which is not convenient for disassembly and cleaning. During the conveying process, the material is prone to leak from the connection, affecting production safety. When cleaning or maintenance is required, the existing screw conveyors are complicated to disassemble and inconvenient to operate. Utility Model Content:

[0004] To address these issues, this invention provides a mixing tank discharge device to overcome the problems of existing screw conveyor devices being mostly fixed connections with mixing tanks, which are inconvenient to disassemble and clean, and materials easily leaking from the connection points during conveying, affecting production safety. Furthermore, existing screw conveyor devices are complex to disassemble and inconvenient to operate when cleaning or maintenance is required.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 , Figure 2 As shown, a mixing tank discharge device includes a mixing tank 1. The bottom discharge end of the mixing tank 1 is connected to a screw conveyor 2 via a connecting assembly. The screw conveyor 2 is fixed on a support base. The connecting assembly is detachably connected to the mixing tank 1 and the screw conveyor 2, respectively, which facilitates disassembly and unblocking. The screw conveyor 2 can transport the mixed raw materials into the guide pipe.

[0023] Specifically:

[0024] The connecting assembly can transport the mixed raw materials in the mixing tank 1 to the screw conveyor, which then transports them to the guide pipe through the rotation of the screw conveyor. The screw blades of the screw conveyor push the raw materials forward during rotation, ensuring continuous and uniform delivery. At the same time, the detachable design of the connecting assembly allows for quick disassembly and maintenance if blockages occur or cleaning is required during the conveying process.

[0025] The screw conveyor 2 includes a conveying barrel, a screw conveying rod is provided inside the conveying barrel, one end of the screw conveying rod passes through the conveying barrel and is fixedly connected to the drive motor, and a guide pipe is fixedly connected to the other end of the conveying barrel. An opening is fixedly provided at the top of the conveying barrel, and a connecting component is provided at the opening. The connecting component can completely cover the opening at the top of the conveying barrel.

[0026] The connecting assembly includes a connector and a sliding member. The connector and the sliding member are respectively located at the opening at the top of the conveying barrel and are fixedly connected to the bottom discharge end of the mixing tank 1. The sliding member is inserted into the side end of the connector and is slidably connected to the conveying barrel.

[0027] Specifically:

[0028] During normal operation, the sliding parts and connecting parts are tightly engaged, completely sealing the opening at the top of the conveying barrel, ensuring the sealed conveying of raw materials within the barrel.

[0029] When cleaning or maintenance of the screw conveyor is required, the sliding component can be removed from the connector to open the top opening of the conveyor barrel for cleaning or maintenance. Since the sliding component is slidably connected to the conveyor barrel, the operation is simple and quick, improving the maintainability of the equipment.

[0030] The connector includes a discharge pipe 3 and a connecting pipe 4. Flanges are fixed on the discharge pipe 3 and the connecting pipe 4 respectively, and the two flanges are fixedly connected by multiple bolts. A first arc-shaped cover plate 5 is fixedly connected to the bottom of the connecting pipe 4, and the first arc-shaped cover plate 5 covers the opening at the top of the conveying barrel.

[0031] The sliding component includes a second arc-shaped cover plate 6, which covers the opening at the top of the conveying barrel and is slidably connected to the conveying barrel. A protruding plate is fixed at the side end of the second arc-shaped cover plate 6, which can fit into the groove for insertion. The groove is fixed to the side of the first arc-shaped cover plate 5.

[0032] The other end of the second arc-shaped cover plate 6 is fixedly connected to the fixing plate by bolts, and the fixing plate is fixed to the side of the conveying barrel.

[0033] The inner sides of the first arc-shaped cover plate 5 and the second arc-shaped cover plate 6 are respectively fitted to the outer side of the conveying barrel, and the curvature of the first arc-shaped cover plate 5 and the second arc-shaped cover plate 6 is greater than the curvature of the opening at the top of the conveying barrel.

[0034] Specifically:

[0035] During normal operation, the first arc-shaped cover plate 5 and the second arc-shaped cover plate 6 together cover the opening at the top of the conveying barrel of the screw conveyor 2, forming a sealed state.

[0036] The curvature of the first arc-shaped cover plate 5 and the second arc-shaped cover plate 6 is greater than the curvature of the opening at the top of the conveying barrel, ensuring that they can completely cover the opening and fit tightly against the outer side of the conveying barrel to form a good sealing effect.

[0037] When cleaning or maintenance of the screw conveyor is required, the second arc-shaped cover plate 6 can be slid along the groove to open the top opening of the conveying barrel for cleaning or maintenance. Because the second arc-shaped cover plate 6 is slidably connected to the conveying barrel, the operation is simple and quick, improving the maintainability of the equipment.

[0038] Meanwhile, the cooperation between the convex plate and the groove, as well as the fixing effect of the fixing plate, ensures stability and sealing during the sliding process.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
