Description

Technical fields:

[0001] This utility model relates to the technical field of improving the service life of the bolts on the water turbine cover plate of a flotation machine, and specifically to a wear-resistant sleeve for the bolts on the water turbine cover plate of a flotation machine. Background technology:

[0002] Foam flotation is the most important method for mineral separation, and the flotation machine is the core equipment in the flotation process, with the water impeller being its core component. The flotation machine involves a complex three-phase physicochemical process involving gas, liquid, and solid phases. The water impeller needs to establish a suitable kinetic environment within the flotation machine for the collision and stable adhesion of valuable mineral particles with bubbles, thereby achieving efficient separation and enrichment of these particles. However, the bolts at the tail end, which pass through the water impeller cover plate, are constantly exposed to corrosive media such as slurry and reagents, and are subjected to vibration and impact from rotation, making them highly susceptible to wear. Traditional bolt materials often cannot withstand the long-term effects of this harsh environment, leading to severe bolt wear and potentially causing the water impeller cover plate to detach, affecting the normal operation and stability of the flotation machine. Therefore, improving the wear resistance of the bolts on the flotation machine water impeller cover plate has become a problem to be solved. Utility Model Content:

[0003] The purpose of this utility model is to provide wear-resistant sleeves for the bolts of the water turbine cover plate of the flotation machine.

[0004] This utility model is implemented by the following technical solution:

[0005] A wear-resistant sleeve for the bolts of a flotation machine turbine cover plate includes a base sleeve that is fitted around the outside of the bolts and fixed to the turbine cover plate. The side wall of the base sleeve is provided with a groove along the circumference, and the top of the base sleeve is provided with a plurality of notches at equal intervals along the circumference. The notches communicate with the grooves.

[0006] A protective sleeve with a closed top is inserted into the base sleeve. The bottom of the protective sleeve is fixed with protrusions at equal intervals along the circumference, matching the number and size of the notches. The protrusions move through the notches and rotate to be placed in the grooves.

[0007] The protective sleeve is provided with a pad that slides up and down inside. The top of the pad is fixed with a screw rod that is screwed to the top of the protective sleeve. The top of the screw rod is fixed with a handle. The bottom of the pad is fixed with a rubber block that is pressed against the bolt.

[0008] Preferably, a wear-resistant washer is fixed to the bottom of the groove.

[0009] Preferably, the outer surface of the protective sleeve is provided with plum blossom-shaped anti-slip grooves along the circumference.

[0010] Preferably, the inner wall of the protective sleeve is provided with a groove that allows the side wall of the pad to slide.

[0011] The advantages of this invention are: the protective sleeve, with multiple bosses passing through the recess and rotating to fit into the groove, achieves a quick and convenient connection with the base sleeve. The protective sleeve, base sleeve, and their surfaces have an anti-corrosion coating, preventing the bolts from being exposed to corrosive media such as slurry and reagents for extended periods, thus extending their service life. The rubber block compresses the bolts, reducing excessive vibration and impact from rotation, which can lead to loosening and wear. This prevents severe bolt wear, avoids easy detachment of the turbine cover, and improves the normal operation and stability of the flotation machine. Attached image description:

[0018] 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.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the wear-resistant sleeve for the flotation machine water turbine cover plate bolts includes a base sleeve 1 that is fitted on the outside of the bolts and fixed to the water turbine cover plate. The side wall of the base sleeve 1 is provided with a groove 2 along the circumference, and the top of the base sleeve 1 is provided with a plurality of notches 3 at equal intervals along the circumference. The notches 3 are connected to the grooves 2.

[0020] A protective sleeve 4 with a closed top is inserted into the base sleeve 1. The bottom of the protective sleeve 4 is fixed with bosses 5 at equal intervals along the circumference, matching the number and size of the recesses 3. The bosses 5 move through the recesses 3 and rotate before being placed in the grooves 2.

[0021] The protective sleeve 4 passes downward through the notch 3 via multiple protrusions 5 and is placed in the groove 2 after rotation, thus achieving a quick and convenient connection with the base sleeve 1.

[0022] The base sleeve 1 and its groove 2, notch 3, and the protective sleeve 4 and its boss 5 are all coated with a corrosion-resistant coating.

[0023] The protective sleeve 4 has a pad 6 that slides up and down inside. The top of the pad 6 is fixed with a screw 7 that is screwed to the top of the protective sleeve 4. The top of the screw 7 is fixed with a handle 8. The bottom of the pad 6 is fixed with a rubber block 9 that is pressed against the bolt.

[0024] When the protective sleeve 4 is connected to the base sleeve 1, the rubber block 9 squeezes the bolt, making the bolt fit tightly with the water turbine cover plate, reducing the loosening and wear of the bolt caused by the impact of water turbine vibration and rotation. The screw 7 is moved up and down by rotating the handle 8, thereby adjusting the tightness of the rubber block 9 squeezing the bolt.

[0025] A wear-resistant washer 10 is fixed to the bottom of the groove 2.

[0026] The outer surface of the protective sleeve 4 is provided with plum blossom-shaped anti-slip grooves 11 along the circumference, which facilitates manual rotation.

[0027] The inner wall of the protective sleeve 4 is provided with a groove 11 that allows the side wall of the pad 6 to slide, thus stabilizing the movement direction of the pad 6.

[0028] Advantages: The protective sleeve 4, through multiple protrusions 5 passing through the recess 3 and rotating, is placed in the groove 2, achieving a quick and convenient connection with the base sleeve 1, and also facilitating the replacement of the protective sleeve 4; the protective sleeve 4, the base sleeve 1, and their surfaces have anti-corrosion coatings, covering the outside of the bolts, which can prevent the bolts from being exposed to corrosive media such as slurry and reagents for a long time, thus extending their service life; the rubber block 9 compresses the bolts, reducing the excessive vibration and impact caused by rotation, which can lead to loosening and wear. This prevents severe bolt wear, prevents the water wheel cover plate from easily falling off, and improves the normal operation and stability of the flotation machine.

[0029] 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.
