Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, specifically a device for solving the wear of the wetted feed inlet of a hydrocyclone. Background Technology

[0002] In the coal washing and processing process, it is usually necessary to properly mix the densities for washing and separation into three products: refined, medium, and gangue. Density mixing must be completed in the wetting tank before the coal enters the hydrocyclone for further separation. Density mixing in the wetting tank is an essential step in the washing process. Existing wetting tanks are single units, with the discharge cone being the most severely worn part. Severe wear leads to uneven density of the sprayed material. Replacing the entire wetting tank is costly, and the replaced tank only shows significant wear at the discharge cone, while other parts are within normal wear ranges. Therefore, this not only results in high costs but also wastes resources. This application proposes a device to address the wear problem at the wetting discharge port of a hydrocyclone. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] In view of the shortcomings of the prior art, this utility model provides a device for solving the wear of the wetted feed port of a hydrocyclone, thus solving the technical problems mentioned in the background.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a device for solving the wear of the wetted feed port of a hydrocyclone, comprising a combined wetting tank, wherein the bottom end of the combined wetting tank is connected to a feed section via a flange, and the bottom end of the feed section is connected to a feed pipe via a flange, and the bottom end of the feed pipe is connected to the hydrocyclone via a flange.

[0007] Preferably, the feed section is a tapered pipe that is wider at the top and narrower at the bottom.

[0008] Preferably, the height of the feed section is greater than 10cm.

[0009] (III) Beneficial Effects

[0010] The beneficial effects of this utility model are as follows:

[0011] This device for solving the wear problem at the wetted feed inlet of a hydrocyclone involves installing a feed section at the bottom of the hydrocyclone wetting tank. When the feed section becomes severely worn or leaks, only the bolts on the flange need to be removed, and the feed section can be disassembled and replaced. This allows for the quick replacement of the feed section at the bottom of the hydrocyclone wetting tank that is most severely worn. It also eliminates the need for special operations such as working at heights or lifting large objects, reducing safety risks and effectively improving maintenance efficiency. At the same time, compared to replacing the entire hydrocyclone wetting tank, material and labor costs can be significantly reduced. Attached Figure Description

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] like Figure 1-4As shown, this utility model provides a technical solution: a device for solving the wear of the wetted feed inlet of a hydrocyclone, including a combined wetting tank 1. The bottom end of the combined wetting tank 1 is connected to the feed inlet section 2 via a flange. The feed inlet section 2 is low-cost and simple to replace individually, and can quickly and effectively complete the precise replacement of the worn parts. The feed inlet section 2 is a tapered pipe that is wider at the top and narrower at the bottom, which can be used to withstand the friction of the sprayed material. The height of the feed inlet section 2 is greater than 10cm. When the feed inlet section 2 is severely worn or leaking, it is only necessary to remove the bolts on the flange to replace the feed inlet section. After disassembling and replacing section 2, the most severely worn part of the feed section 2 at the bottom of the wetting tank 1 can be quickly replaced. This eliminates the need for special operations such as working at heights or lifting large objects, reducing safety risks and effectively improving maintenance efficiency. Compared to replacing the entire wetting tank, material and labor costs are significantly reduced. The bottom of the feed section 2 is connected to the feed pipe 3 via a flange, and the bottom of the feed pipe 3 is connected to the hydrocyclone 4 via a flange.

[0019] The operational steps for this application are as follows:

[0020] When the feed section 2 is severely worn or leaking, remove the bolts on the flange of the feed section 2, disassemble the feed section 2 and replace it, so as to replace the feed section 2 at the bottom of the medium wetting tank 1 where the wear is most severe.
