Tailing cone valve sealing device for flotation column

Abstract

The utility model discloses a tailing cone valve sealing device for a flotation column. The tailing cone valve sealing device comprises a fastener, a lining and a support. The support is installed on the sealing assembly, the lining is installed on the support through abrasion-resistant materials, and the fastener is installed on the support in a threaded connection mode and matched with the support to adjust the attaching degree of the lining and a valve rod of the tailing cone valve, so that the sealing effect is improved. When the sealing assembly is abraded, only the fastener needs to be screwed out, the lining is placed on the support in the middle, then the fastener is screwed to enable the lining to be tightly attached to the valve rod, and replacement can be completed. Therefore, the leakage risk of the tailing cone valve is reduced, the labor intensity and the safety risk of operation and maintenance personnel are effectively reduced, and the service life of the sealing device can be effectively prolonged while the labor intensity is reduced.

Description

Technical Field

[0001] This utility model relates to a tailings cone valve sealing device in the mineral processing industry, specifically a tailings cone valve sealing device for flotation columns. Background Technology

[0002] In the non-ferrous and ferrous metal beneficiation industries, flotation columns are commonly used flotation equipment. The liquid level control method for flotation columns typically employs an interlocking control between a liquid level float and a tailings cone valve. During liquid level control, the tailings cone valve frequently switches between open and closed, resulting in frequent operation. Over long periods, direct contact and friction between the valve stem and the sealing components cause rapid wear of the sealing components, making the tailings cone valve prone to leakage. This necessitates frequent and intensive cleaning by on-site operators. Furthermore, due to the heavy weight of each tailings cone valve, replacement is not only labor-intensive but also poses significant safety risks.

[0003] In order to effectively control the leakage problem of tailings cone valves, reduce safety risks and labor intensity, and improve the service life of seals, it is necessary to develop a sealing device for flotation column tailings cone valves to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sealing device for the tailings cone valve of a flotation column to solve the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The tailings cone valve sealing device consists of fasteners, a liner, and a support. The support is installed on the tailings cone valve sealing assembly, the liner is centrally placed on the support, and the fasteners are installed on the support. The liner is adjusted to fit tightly against the valve stem by adjusting the thread length.

[0007] Optionally, the fastener has threads on its outer wall for adjusting the pressure of the inner liner to fit tightly against the tailings cone valve stem, while also allowing for flexible adjustment of the tightness of the inner liner.

[0008] Optionally, the inner wall of the liner is fitted tightly against the valve stem, and the outer wall is fitted tightly against the inner wall of the fastener.

[0009] Optionally, the inner wall of the support is threaded, the lower part is used to press the packing, and the flange is used to connect with the tailings cone valve sealing assembly. It is adjusted in conjunction with fasteners and lining to improve the sealing effect.

[0010] Compared with the prior art, this utility model provides a sealing device for a flotation column tailings cone valve, which has the following beneficial effects:

[0011] 1. This utility model ensures that the liner and the tailings cone valve stem are always in close contact by adjusting the thread depth of the fasteners. It is simple to operate, provides a good seal, and effectively reduces the workload and safety risks for operators and maintenance personnel. Furthermore, the liner is made of wear-resistant material, ensuring a long service life. The fasteners are threaded, and the liner is placed directly on the support, which is then bolted to the tailings cone valve sealing assembly, making installation convenient.

[0012] 2. This utility model includes fasteners, lining, and support, and has a simple structure, low production and maintenance costs, and is easy to maintain. Attached Figure Description

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

[0018] Please see Figures 1-3 A tailings cone valve sealing device for flotation columns consists of fasteners 21, liner 22, and support 23. After the tailings cone valve 1 and sealing assembly are installed, the support 23 is installed on the sealing assembly. After the support 23 is installed, the liner 22 is placed in the center on the support 23, and the fasteners 21 are installed on the support 23. The liner 22 is adjusted to fit tightly against the cone valve stem 3 by adjusting the thread length.

[0019] When the tailings cone valve 1 is in operation, it switches between closed and open, causing the valve stem to move up and down. During this movement, the valve stem 3 comes into contact with and rubs against the inner lining 22. This friction causes wear on the inner wall of the inner lining 32, resulting in insufficient adhesion between it and the valve stem 3. Slurry then flows out through the gap between the inner wall of the inner lining 22 and the valve stem 3. At this point, the fastener 31 needs to be tightened to lower its height, allowing the inner lining 22 to adhere tightly to the valve stem 3 again until leakage stops. When the fastener 31 can no longer be adjusted, it indicates that the maximum adjustment capacity has been reached. If slurry leakage occurs at this point, simply unscrew the fastener 31, place the new inner lining 32 centrally on the support 33, and tighten the fastener 31 again to complete the replacement.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
