Description

Technical Field

[0001] This utility model belongs to the field of metal mineral processing, and in particular relates to a device for preventing slurry splashing into a ore box. Background Technology

[0002] Two-phase flow of gas and liquid in slurry transportation is a common fluid transport phenomenon. During the transport of slurry through pipelines into the raw material tank, the presence of air within the slurry causes slurry spraying and splashing as it exits the pipeline. This spraying and splashing can injure workers on the work site and those taking samples, while also affecting sampling work and reducing efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a device for preventing slurry splashing into a ore box, so as to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the specific technical solution of the present invention for an anti-slurry splashing ore box device is as follows:

[0005] A slurry splash prevention device includes a slurry container, a feed pipe connected to one end of the slurry container, and a discharge port on the side wall of the other end of the slurry container. The slurry container includes a buffer tank and a raw material tank, which are connected. The feed pipe is connected to the end of the buffer tank opposite to the raw material tank, and the discharge port is located on the side wall opposite to the buffer tank. An opening is located on the top surface of the raw material tank.

[0006] Furthermore, the feed pipe extends into the buffer box, and the extension pipe of the feed pipe inside the buffer box is inclined toward the bottom surface of the buffer box.

[0007] Furthermore, the included angle of inclination of the extension tube is 120 degrees.

[0008] Furthermore, the top surface of the buffer box is open, and a steel plate is laid on the top surface of the buffer box.

[0009] Furthermore, the top surface of the raw material box is open, and a grid is laid on its top surface, with openings in the grid.

[0010] Furthermore, the bottom of the ore outlet is higher than the bottom of the raw material box.

[0011] The ore box device for preventing slurry splashing according to this utility model has the following advantages:

[0012] This invention provides a buffer box between the raw material box and the feed pipe. This buffer box dissipates the splashing kinetic energy of the gas-liquid two-phase flow phenomenon in the slurry and protects the slurry from splashing. As a result, the slurry flowing into the raw material box is not affected by the gas-liquid two-phase flow problem, thereby preventing the slurry from splashing out of the raw material box, improving the production operation level and economic benefits of the workshop, and ensuring the safety and stability of the production process.

[0017] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a slurry splash prevention device for a ore box.

[0018] like Figures 1 to 2 As shown, this utility model discloses a slurry splash prevention device, comprising a slurry container, a feed pipe 2 connected to one end of the slurry container, and an outlet 5 for outward discharge on the side wall of the other end of the slurry container, with the bottom of the outlet 5 higher than the bottom surface of the slurry container. The slurry entering the slurry container through the feed pipe 2 is stored inside, and when the stored slurry is higher than the bottom surface of the outlet 5, it overflows outward through the outlet 5. The fact that the bottom surface of the outlet 5 is higher than the bottom surface of the slurry container allows for sedimentation of the material stored in the slurry container, preventing large particles of sediment from entering downstream equipment and ensuring the stability of the slurry concentration and particle distribution.

[0019] Specifically, the ore box consists of a buffer box 1 and a raw material box 3, which are interconnected. The feed pipe 2 is connected to the end of the buffer box 1 opposite to the raw material box 3. The outlet 5 is located on the side wall of the raw material box 3 opposite to the buffer box 1, and the bottom surface of the outlet 5 is higher than the bottom surface of the raw material box 3. The slurry can enter the buffer box 1 through the feed pipe 2. The buffer box 1 dissipates the kinetic energy of the gas-liquid two-phase flow of the slurry. Simultaneously, the buffer box 1 prevents the slurry from being splashed out of the ore box by the kinetic energy released at the outlet of the feed pipe 2, thus improving the safety of workers and sampling personnel at the workstation and increasing the efficiency of sampling personnel. For the convenience of sampling personnel, an opening is provided on the top surface of the raw material box 3.

[0020] The buffer box 1 is a 14060*2500*1500 cuboid, and the raw material box 3 is a 2000*2500*1500 cuboid. The length of the buffer box 1 is greater than the length of the raw material box 3, so as to provide sufficient buffer space for the slurry sprayed from the feed pipe 2 and effectively prevent the phenomenon of slurry spraying.

[0021] Preferably, the feed pipe 2 extends into the buffer tank 1, and the extension pipe of the feed pipe 2 inside the buffer tank 1 is inclined towards the bottom surface of the buffer tank 1. In this way, the slurry entering the buffer tank 1 through the feed pipe 2 will be sprayed towards the bottom surface of the buffer tank 1. When the slurry in the buffer tank 1 has a certain storage volume, the slurry will be sprayed into the slurry in the buffer tank 1 to further consume the kinetic energy of the sprayed slurry and prevent the slurry sprayed from the feed pipe 2 from splashing out of the raw material tank 3. The inclined angle of the extension pipe is preferably 120 degrees.

[0022] like Figure 1 and Figure 2 As shown, the top surface of the buffer box 1 has an opening 7, and a steel plate 4 is laid on the top surface of the buffer box 1 to allow personnel to walk on it. At the same time, the top surface of the raw material box 3 also has an opening 7, and a grid 6 is laid on its top surface. The grid 6 has openings, which facilitates the observation of the slurry inside.

[0023] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
