Description

Technical Field

[0001] This utility model relates to an automatic separation and processing device for large-particle ore and attached liquid after mill screening, belonging to the field of tool technology. Background Technology

[0002] In the alumina production process, the slurry formed after ore grinding in a mill needs to undergo large-particle separation, a crucial pretreatment step affecting subsequent leaching processes. Currently, the slurry passing through the mill discharge screen typically contains large-particle ore directly discharged, and the large particles and accompanying slurry liquid often require manual intervention for cleaning. Operators need to frequently clean, unclog, or assist in separation, which is not only labor-intensive and consumes a lot of human resources but is also inefficient, easily causing production disruptions and significantly impacting overall production efficiency and cost control. Existing technology lacks a simple device that can directly adapt to the processing of large-particle ore after mill discharge screening and achieve efficient and continuous separation.

[0003] Therefore, there is a need for a mill solid-liquid separation receiving plate that can automatically and smoothly complete the initial solid-liquid separation of large-particle ore and its accompanying liquid at the mill discharge screen by utilizing the material's own gravity or flow characteristics, in order to solve the time-consuming and labor-intensive problems caused by manual assistance and improve the level of production automation and efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an automatic separation and processing device for large particles of ore and attached liquid after mill screening. It can automatically and smoothly complete the solid-liquid separation of large particles of ore and attached liquid at the mill discharge screen by utilizing the material's own gravity or flow characteristics, so as to solve the time-consuming and labor-intensive problems caused by manual assistance, improve the level of production automation and efficiency, and overcome the shortcomings of the existing technology.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] This utility model discloses an automatic separation and treatment device for large particles of ore and attached liquid after mill screening. It includes a solid-liquid separation screen that is connected to the mill discharge screen and is inclined. A liquid guide channel is provided directly below the solid-liquid separation screen. A solid guide channel for solid particles to fall into is provided at the lower end of the solid-liquid separation screen. A discharge pipe is provided at the bottom of both the liquid guide channel and the solid guide channel.

[0007] The aforementioned solid guide channels all have a structure that is larger at the top and smaller at the bottom, with the lower end of the solid guide channel converging towards the pipe arrangement direction.

[0008] As mentioned above, support rods supporting the liquid guide tank and solid guide tank are provided at the upper end to the ground.

[0009] As mentioned above, baffles are provided on both the left and right sides of the solid-liquid separation mesh.

[0010] The aforementioned pipes are seamless steel pipes ranging from DN50 to DN300.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses an inclined solid-liquid separation net to separate solids and liquids. The liquid falls downward into the liquid guide trough and is fixed under the impact of gravity or flow force, automatically falling into the solid guide trough and discharged through their respective discharge pipes, realizing gravity-flow solid-liquid separation. It can utilize the material's own gravity or flow characteristics to automatically and smoothly complete the initial solid-liquid separation at the discharge port, thus solving the time-consuming and labor-intensive problems caused by manual assistance and improving the level of production automation and efficiency.

[0013] 2. The solid guide channels are all of a structure that is wider at the top and narrower at the bottom, with the lower end of the solid guide channel converging towards the discharge pipe. This facilitates the guidance of liquid and solid towards the discharge pipe for effective discharge. Other advantages, objectives, and features of this utility model will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this utility model. The objectives and other advantages of this utility model can be realized and obtained through the following description. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings, wherein:

[0015] Figure 1 This is a schematic diagram of the three-dimensional connection structure of this utility model.

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0020] like Figures 1-3As shown, this utility model discloses an automatic separation and treatment device for large particles of ore and attached liquid after mill screening. It includes a solid-liquid separation net 2 that is connected to the mill discharge screen 1 and is inclined. A liquid guide trough 3 is provided directly below the solid-liquid separation net 2, and a solid guide trough 4 is provided at the lower end of the solid-liquid separation net 2 for solid particles to fall into. Both the liquid guide trough 3 and the solid guide trough 4 are provided with discharge pipes 5 at the bottom. Specifically, the discharge pipes 5 are DN50-DN300 seamless steel pipes. With this structure, the solid and liquid can be separated by the inclined solid-liquid separation net 2. The liquid falls downward into the liquid guide trough 3 and is fixed under the impact of gravity or flow force, and automatically falls into the solid guide trough 4, and is discharged through their respective discharge pipes 5, realizing gravity-flow solid-liquid separation.

[0021] Furthermore, the solid guide channels 4 are all of a structure that is larger at the top and smaller at the bottom, with the lower end of the solid guide channels 4 converging towards the discharge pipe 5. This facilitates the flow of liquid and solid towards the discharge pipe 5 for discharge.

[0022] Furthermore, support rods 6 are provided at the upper ends of the liquid guide channel 3 and the solid guide channel 4, which support the ground. The support rods help to provide stable support for the device.

[0023] Furthermore, baffles 7 are provided on both the left and right sides of the solid-liquid separation net 2. This structure helps to prevent solid materials from falling from the left and right sides of the solid-liquid separation net 2.

[0024] During use, under the action of gravity, the liquid falls into the liquid guide trough 4 below the solid-liquid separation net 2, while the solid falls into the solid guide trough 4 automatically due to gravity and the impact force of the falling material.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to restrict the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments without departing from the technical solution of the present utility model and based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
