Description

Technical Field

[0001] This utility model belongs to the field of mineral processing, and in particular relates to a thickener. Background Technology

[0002] A thickener is a device used for solid-liquid separation, primarily in industries such as mining. Its main function is to separate solid particles suspended in a liquid through gravity settling, thus achieving solid-liquid separation. This equipment can effectively increase the concentration of the concentrate, reduce the moisture content in subsequent processing steps, and lower processing costs.

[0003] Because thickeners have a large load capacity, they require high strength. Therefore, how to increase the strength of thickeners has become a problem that urgently needs to be solved by those skilled in the art. In addition, since the slurry after sedimentation and thickening needs to be discharged from the port at the bottom of the thickener, how to facilitate the discharge of the thickened slurry is also an urgent problem to be solved. Utility Model Content

[0004] In view of this, the present invention aims to provide a thickener to improve the strength of the thickener and facilitate the discharge of the thickened slurry.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0012] The reinforced support structure includes two support columns supported on the foundation and symmetrically arranged on the left and right sides of the thickening tank. The top of the support columns is connected by a crossbeam, and two inclined bases are provided on the top of the crossbeam. Each inclined base is connected and fixed to one half of the thickening tank.

[0013] Furthermore, a collection trough is provided at the bottom port of the thickening tank. The collection trough has a circular tube structure, and a flange for connecting to the discharge pipe is provided at the bottom opening of the collection trough.

Detailed Implementation

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figure 1 , Figure 2 As shown, a thickener includes a thickener housing 4, which is an annular structure with openings at both the top and bottom. The top opening is the upper port of the thickener housing 4, and the bottom opening is the lower port of the thickener housing 4. An inverted conical thickener tank 3 is installed at the lower port of the thickener housing 4, and a collection trough 1 is provided at the lower port of the thickener tank 3. In this invention, the thickener tank 3 is made of steel plate and is designed in two separate parts, including two symmetrical halves. These two halves are directly opposite each other and connected by welding to form the inverted conical thickener tank. The thickener tank 3 is supported by several support frames evenly arranged in the circumferential direction.

[0032] Each support frame includes two support rods 9, each arranged along the busbar of the thickener 3. The support rods 9 are directly welded to the surface of the thickener 3 wall, or fixed to the surface of the thickener 3 wall using flanges or inclined bases. The two support rods 9 are each equipped with the same number of uprights 2, which are supported on a foundation. Each upright 2 is topped with an inclined base 10, which is a conventional structure and will not be described in detail here. The uprights 2 are connected and fixed to the corresponding support rods 9 via the inclined bases 10, thus supporting the thickener 3, and consequently, the thickener itself. To improve the stability of the support frame, the two outermost uprights 2 are connected by a fixing structure.

[0033] Fixed structures such as Figure 3 As shown, the structure includes two diagonal braces 7 that intersect and are fixedly connected at the intersection. The two columns 2 corresponding to the fixed structure are connected by the two diagonal braces 7. The diagonal braces can be connected to the corresponding columns using flanges. The cross-braces connecting the two columns is an existing structure and will not be described in detail here.

[0034] In this invention, to further improve the stability of the support frame, two diagonal braces 7 are arranged in the same vertical plane. One of the diagonal braces 7 is configured as a split structure, comprising two separate rods 71, while the other diagonal brace 7 remains an integral structure. The two separate rods 71 ​​are located on opposite sides of the integral diagonal brace 7, and are connected by a connecting plate 8. The connecting plate 8 is located outside the vertical plane containing the two diagonal braces 7, and the integral diagonal brace 7 is fixed to the connecting plate 8. For example, the two separate rods 71 ​​are welded to both ends of one side of the connecting plate 8, and the connecting plate 8 is welded to the integral diagonal brace 7 on the same side, thus connecting and fixing the two intersecting diagonal braces 7 at their intersection point within the same vertical plane. Since the two diagonal braces 7 are located within the same support surface, the supporting force is evenly distributed, improving the stability of the support frame.

[0035] In this invention, an even number of support frames are provided, symmetrically arranged on the left and right sides of the thickener 3. This means that the two halves of the thickener are supported by an equal number of support frames, and the support positions are symmetrical. The thickener is welded from two halves. To ensure the stability of the thickener, a reinforcing support structure is provided between the two support frames at the connection point of the two halves. Specifically, a reinforcing support structure is provided between the left and right support frames at the connection point of the two halves. The two halves of the thickener are connected and supported by floats through the reinforcing support structure, thereby improving the strength of the thickener to meet usage requirements.

[0036] Strengthen the supporting structure, such as Figure 1 , Figure 5As shown, the system includes two support columns 15 supported on the foundation and symmetrically arranged on the left and right sides of the thickening tank 3. The tops of the support columns 15 are connected by a crossbeam 17. Two inclined bases 10 are provided on the top of the crossbeam 17, and each inclined base 10 is connected and fixed to one half of the thickening tank 3. The reinforced support structure provides auxiliary support at the welding positions of the two halves of the thickening tank 3 to ensure the stability of the thickening tank itself.

[0037] In this utility model, a material collection trough 1 is provided at the bottom port of the thickener 3, such as... Figure 6 As shown, the collecting trough 1 is a circular tube structure. The bottom opening of the collecting trough 1 is provided with a flange for connecting to the discharge pipe. Two auxiliary discharge ports 101 are symmetrically arranged on the wall of the collecting trough 1. During use, the thickened slurry is discharged through the bottom opening of the collecting trough 1 and the two auxiliary discharge ports 101, which can prevent the collecting trough 1 from being blocked and facilitate the discharge of slurry.

[0038] In this invention, two mounting structures are respectively provided at both ends of one diameter of the thickener housing 4. The two mounting structures face each other, that is, they are arranged opposite each other at both ends of the thickener housing 4. The mounting structures are as follows: Figure 1 , Figure 2 and Figure 4 As shown, the system includes two vertical rods 14, both fixed to the outer surface of the wall of the thickener housing 4, with the tops of both rods extending beyond the top of the thickener housing 4. The bottom ends of the two rods 14 are connected by arc-shaped plates 18 installed on the corresponding walls of the thickener housing 4, with the arc-shaped plates 18 tightly fitted and fixed to the outer surface of the walls of the thickener housing 4. This structure facilitates the subsequent arrangement of cable trays and other facilities between the two installation structures.

[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.
