[0002] In the grinding aid production process, centrifugal pumps are the core conveying equipment. Common centrifugal pumps include structures such as a support frame and pump shaft. Figure 9 It is known that the bracket adopts a hollow structure design. In the actual production scenario of the factory, there is frequent personnel movement in this area, and the rotating parts of the centrifugal pump shaft are exposed due to the hollow design of the bracket, which can easily cause injury to on-site operators and poses a significant safety hazard.

[0003] In the high-temperature and high-pressure process section of grinding aid production, the service life of the centrifugal pump's sealing ring will be greatly affected. The failure of the sealing ring will cause frequent leakage problems at the connection between the pump shaft and the connecting parts. Since liquid brown sugar is required in the raw materials, the above-mentioned leakage problems will not only cause the liquid brown sugar raw material to leak and pollute the factory environment, but also lead to raw material loss and increase the company's production costs.

[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0037] like Figures 1-2As shown in the figure, this embodiment proposes an integrated drainage and protection device for a centrifugal pump supplying grinding aid raw materials, including a protective cover 1. The protective cover 1 includes a vertical plate 11 for providing protection on the personnel flow side. A horizontal plate 12 is connected to the upper end of the vertical plate 11 for providing protection from above. The horizontal plate 12 is connected to the support 31 of the centrifugal pump. The connection methods between the horizontal plate 12 and the support 31 include, but are not limited to, snap-fit, plug-in, bolt-fit, and binding. A downwardly inclined guide plate 13 is connected to the lower end of the vertical plate 11. The inclination angle is to better allow the liquid to flow down and prevent it from stagnating on the guide plate 13. The angle is adjusted according to the flowability of different liquids. The guide plate 13 is set below the pump shaft 32 of the centrifugal pump 3 to receive the liquid leaking between the pump shaft 32 and the seal 33. The vertical plate 11, the horizontal plate 12 and the guide plate 13 form a semi-enclosed structure. The semi-enclosed structure forms a protective space inside, and the pump shaft 32 is built into the protective space. The semi-enclosed structure protects the pump shaft 32 inside, reducing the possibility of workers accidentally touching the rotating pump shaft 32 and causing danger. The downward inclined guide plate 13 plays the role of receiving and guiding the leakage between the pump shaft 32 and the seal 33. Moreover, it can be integrally bent from the plate, and the structure is simple and easy to manufacture.

[0038] In some embodiments, such as Figure 2 As shown, the vertical plate 11 has first side plates 14 on both sides, which form a longitudinal support and improve the protection strength above; the horizontal plate 12 has second side plates 15 on both sides, which are snapped into the two sides of the hollow part of the bracket 31, providing longitudinal support strength and making the connection more stable after installation; the guide plate 13 has third side plates 16 on both sides, which increases the drainage capacity of the guide plate 13 and can still work normally in the event of large flow leakage.

[0039] In some embodiments, such as Figure 2 As shown, the cross-section of the guide plate 13 is V-shaped. The V-shape not only increases the flow rate of the guide plate 13, but also plays a better role in liquid convergence, preventing the liquid from overflowing to both sides.

[0040] In some embodiments, the snap-fit ​​method mentioned above can take the following structural form: (e.g.) Figure 3 As shown, the first side plate 14 has a snap-fit ​​17. The cover 1 is snapped onto the bracket 31 through the snap-fit ​​17. The snap-fit ​​method provides better front-to-back bearing force, making the cover 1 more stable.

[0041] In some embodiments, such as Figure 4 , Figure 5As shown, the entire device also includes a fixture 18, which includes a U-shaped frame 181 and a hand screw 182. The U-shaped frame 181 is fixedly connected to the lower surface of the horizontal plate 12 and can be connected by welding or bonding. The hand screw 182 passes through the through hole 121 on the horizontal plate and is threadedly connected to the U-shaped frame 181. In use, the U-shaped frame 181 is snapped onto the bracket 31, and the hand screw 182 is tightened to securely and conveniently connect the two. The fixture can be used with brackets 31 of different styles and thicknesses, thus having a wider range of applications.

[0042] In some embodiments, such as Figure 6 , Figure 7 As shown, the entire device also includes a front cover 19, which is rotatably connected to the front end of the second side plate 15. This can be achieved by setting a rotating shaft 192 on the front cover 19 and cooperating with a connecting ring 151 on the second side plate. The front cover 19 has baffles 193 connected to both sides of it, which cooperate with the second side plate 15. The front cover 19 can provide more comprehensive protection to adapt to different production environments in the factory. The rotatable connection ensures that the front cover 19 will not affect the ease of installation of the protective cover 1. The baffles 193 can limit the rotation angle and prevent the front cover 19 from rotating inward and damaging the rotating part of the centrifugal pump 3. The vertical plate 11 and the front cover 19 can also be provided with vertical plate heat dissipation holes 111 and front cover heat dissipation holes 191 to provide heat dissipation.

[0043] In some embodiments, such as Figure 8 As shown, the entire device also includes a collection tank 2, the internal space of which is connected to the end of the guide plate 13. The collection tank 2 can collect the leaked liquid for convenient subsequent processing.

[0044] In some embodiments, such as Figure 8 As shown, the collection bucket 2 includes a bucket body 21, a fixed cover 22, and a movable cover 23. The bucket body 21 serves to contain the leaked liquid. The fixed cover 22 and the movable cover 23 are connected to the top of the bucket body 21. The fixed cover 22 and the movable cover 23 are hinged together. The fixed cover 22 and the movable cover 23 serve to prevent the leaked liquid from being contaminated. Moreover, the movable cover 23 can be opened to take out the leaked liquid or check the leak situation.

[0045] In some embodiments, such as Figure 8 As shown, a slot 25 is provided on the top of the barrel 21, and the guide plate 13 is snapped into the slot 25. The slot in the barrel 21 is to better adapt to the usage scenario. Most pumps are placed on the ground, which makes the outlet of the guide plate 13 very close to the ground. The slot in the barrel 21 makes the connection of the guide plate 13 more stable and makes the collection barrel 2 easier to manufacture. It can be modified from waste barrels, and materials are easier to obtain.

[0046] In some embodiments, such as Figure 8As shown, the entire device also includes a recovery pipe 24 for recovering leaked liquid. A recovery port 26 is opened on the fixed cover 22. The recovery pipe 24 passes through the recovery port 26 and is connected to the fixed cover 22. The recovery pipe 24 can be connected to a suction device to recover and reuse the collected leaked liquid, thereby reducing cost losses.
