Technical Field

[0001] This utility model belongs to the field of flotation machine stator technology, specifically a high-strength flotation machine stator rubber part. Background Technology

[0002] Flotation machines are one of the core pieces of equipment in mineral processing. They mainly consist of a tank, power transmission components, agitation components, and a stator. The agitation components have an impeller at the bottom, which works with the stator to form an impeller-stator system. The form and structure of the stator affect the fluid flow state and flow regime transformation within the equipment, significantly impacting the performance and operating efficiency of the flotation machine.

[0003] Existing flotation machines include types such as aerated flotation machines and self-aspirating flotation machines. The existing rubber stator structure, due to the use of rubber as the material, has weak impact resistance and severe local wear of the blades, which greatly affects the life of the stator. This means that the stator needs to be replaced frequently during the production process. Whenever the stator of the flotation machine is replaced, the flotation machine stops working, which has a significant impact on the output efficiency of the flotation machine.

[0009] Preferably, the steel stator blade has adhesive teeth on its sidewall, and the adhesive teeth are arranged in a linear array.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 4As shown in the embodiment of this utility model, a high-strength flotation machine stator rubber part includes a rubber stator disk 1; a rubber stator blade 2 is fixedly connected to the top of the rubber stator disk 1; a steel stator disk 7 is fixedly connected inside the rubber stator disk 1; a mounting platform 15 is provided on the top of the steel stator disk 7, and multiple mounting platforms 15 are arranged in a circumferential array; a fixing screw 10 is fixedly connected to the top of the mounting platform 15, and multiple fixing screws 10 are arranged in a linear array; a nut 11 is threadedly connected to the top of the fixing screw 10, and a fixing plate 8 is provided between the fixing screw 10 and the nut 11; a steel stator blade 9 is fixedly connected to the top of the fixing plate 8, and multiple steel stator blades 9 are arranged in a circumferential array; during operation, the steel stator disk 7 and the steel stator blades 9, connected together by the fixing screw 10 and the nut 11, strengthen the rubber stator disk 1. Whenever any part of the rubber stator disk 1 or the rubber stator blade 2 is subjected to stress, the position... The steel stator discs 7 or 9 located at corresponding positions inside the rubber stator disc 1 and rubber stator blades 2 can exert forces on the external rubber stator disc 1 and rubber stator blades 2 through their rigid material, thereby offsetting the stress on the rubber stator disc 1 and rubber stator blades 2, thus keeping the rubber stator disc 1 and rubber stator blades 2 stable and preventing deformation. During daily use or installation, the number of rubber stator blades 2 and steel stator blades 9 can be directly controlled by reasonably arranging the number of installation platforms 15, thereby flexibly adjusting the stator of the flotation machine. This step, by setting steel stator discs 7 and steel stator blades 9 inside the rubber stator disc 1 and rubber stator blades 2, strengthens the rubber stator disc 1 and rubber stator blades 2, which helps to prevent deformation of the rubber stator disc 1 and rubber stator blades 2, enhances the flexibility of the rubber stator, expands the application scenarios of the rubber stator, and extends the service life of the rubber stator.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, a fixing ring 6 is fixed to the side wall of the steel stator plate 7, and four fixing rings 6 are arranged in a circular array. A fixing groove 16 is opened on the top of the fixing ring 6. During operation, after the operator installs all the steel stator blades 9 inside the mounting platform 15 using the fixing screws 10 and nuts 11, the steel stator plate 7 and steel stator blades 9 can be placed in the rubber mold with the help of the symmetrically arranged fixing rings 6 and fixing grooves 16, thereby fixing the rubber stator plate 1 to the outer surface of the steel stator plate 7, and thus fixing the rubber stator blades 2 to the outer surface of the steel stator blades 9. This step, by setting the fixing rings 6 and opening the fixing grooves 16 on the top of the fixing rings 6, assists in the fixing process of the rubber stator plate 1, rubber stator blades 2 and steel stator plate 7, steel stator blades 9, which helps to solve the molding problem of the rubber mold and makes the fixing of the rubber stator plate 1, rubber stator blades 2 and steel stator plate 7, steel stator blades 9 more compact.

[0026] like Figure 2 and Figure 3 As shown, a diagonal brace 14 is fixedly connected to the top of the fixed plate 8, and multiple diagonal braces 14 are arranged in a linear array. The side walls of the multiple diagonal braces 14 are fixed to the side walls of the steel stator blade 9. During operation, multiple diagonal braces 14 simultaneously connect the fixed plate 8 and the steel stator blade 9. Whenever the steel stator blade 9 is subjected to a tangential force transmitted from the rubber stator blade 2, the multiple diagonal braces 14 can provide resistance stress to the steel stator blade 9 through themselves, thereby offsetting the tangential force. This step, by setting multiple diagonal braces 14, enhances the shear resistance of the steel stator blade 9, which helps to solve the problem of weak shear resistance caused by the thin shape of the steel stator blade 9, thereby improving the service life of the steel stator blade 9 and the reusability of the steel stator blade 9.

[0027] like Figure 2 and Figure 3 As shown, the steel stator blade 9 has bonding teeth 13 on its sidewall, and the bonding teeth 13 are arranged in a linear array. During operation, since the rubber stator blade 2 is always affected by the external force from the slurry, the probability of demolding between the steel stator blade 9 and the rubber stator blade 2 is higher. After the steel stator blade 9 is connected to the rubber stator blade 2 through the mold, the bonding teeth 13 arranged in a linear array can make the bonding between the steel stator blade 9 and the rubber stator blade 2 more compact through the concavity of the sidewall of the steel stator blade 9 and its own serrated shape. This step, by setting the bonding teeth 13 arranged in a linear array, improves the bonding degree between the steel stator blade 9 and the rubber stator blade 2, which helps to reduce the demolding problem between the steel stator blade 9 and the rubber stator blade 2, enhances the stability of the rubber stator, and extends the service life of the rubber stator.

[0028] like Figure 1 and Figure 2 As shown, one side wall of the rubber stator blade 2 is provided with a blade back surface 3, and the other side wall of the rubber stator blade 2 corresponding to the blade back surface 3 is provided with a blade front surface 4. During operation, the operator should ensure that the slurry first contacts the blade back surface 3 in the direction of movement, and then contacts the blade front surface 4. With the help of the convex shape of the blade back surface 3 and the concave shape of the blade front surface 4, the rubber stator can better perform its function. This step, by setting the blade back surface 3 and the blade front surface 4 on the two side walls of the rubber stator blade 2, improves the functional structure of the rubber stator, enhances the slurry blocking ability of the rubber stator blade 2, and is conducive to the efficient operation of the flotation machine.

[0029] like Figure 1 Of Figure 4As shown, the steel stator plate 7 has a reserved installation sleeve 5 inside, and the top and bottom of the reserved installation sleeve 5 penetrate the side wall of the rubber stator plate 1 respectively. During operation, the top of the reserved installation sleeve 5 is above the top of the rubber stator plate 1, and the bottom of the reserved installation sleeve 5 is below the bottom of the rubber stator plate 1. The operator can install the rubber stator inside the flotation machine through the reserved installation sleeve 5. With the rigid material of the steel stator plate 7, the four reserved installation sleeves 5 can fix the rubber stator relatively stably. This step solves the installation problem of the rubber stator by reserving the installation position of the rubber stator by setting the reserved installation sleeve 5, and improves the usability and convenience of the rubber stator.

[0030] like Figure 2 and Figure 3 As shown, the side wall of the steel stator blade 9 is provided with rubber interconnection holes 12. During operation, after the rubber stator blade 2 and the steel stator blade 9 are bonded together, a portion of the rubber inside the rubber stator blade 2 can be connected to each other through the rubber interconnection holes 12 on the side wall of the steel stator blade 9. With the help of this portion of rubber connected inside the rubber interconnection holes 12, the bonding strength between the rubber stator blade 2 and the steel stator blade 9 is further improved. This step, by opening the rubber interconnection holes 12 on the side wall of the steel stator blade 9, allows a portion of the rubber inside the rubber stator blade 2 to be connected to each other, further improving the stability of the rubber stator and helping the rubber stator maintain stability during high-intensity production processes.

[0031] During operation, the steel stator plate 7 and steel stator blade 9, connected by the fixing screw 10 and nut 11, strengthen the rubber stator plate 1. Whenever the rubber stator plate 1 or rubber stator blade 2 is subjected to stress, the steel stator plate 7 or steel stator blade 9 located at corresponding positions inside the rubber stator plate 1 and rubber stator blade 2 can exert a force on the external rubber stator plate 1 and rubber stator blade 2 through their rigid material, thereby offsetting the stress on the rubber stator plate 1 and rubber stator blade 2, thus keeping the rubber stator plate 1 and rubber stator blade 2 stable and preventing deformation. In daily use or installation, workers can adjust the number of mounting platforms 15 by properly arranging them. This allows for direct control of the number of rubber stator blades 2 and steel stator blades 9, enabling flexible adjustment of the flotation machine stator. After the operator installs all the steel stator blades 9 inside the mounting platform 15 using the fixing screws 10 and nuts 11, the steel stator disc 7 and steel stator blades 9 can be placed in the rubber mold using the symmetrically arranged fixing rings 6 and fixing grooves 16. This fixes the rubber stator disc 1 to the outer surface of the steel stator disc 7, and thus fixes the rubber stator blades 2 to the outer surface of the steel stator blades 9. Multiple inclined support blocks 14 simultaneously connect the fixing plate 8 and the steel stator blades 9. Whenever the steel stator blade 9 is subjected to a tangential force transmitted from the rubber stator blades 2, the multiple inclined support blocks 14 can... The steel stator blade 9 itself provides resistance stress to counteract the tangential force. Since the rubber stator blade 2 is always affected by the external force from the slurry, the probability of demolding between the steel stator blade 9 and the rubber stator blade 2 is higher. After the steel stator blade 9 is connected to the rubber stator blade 2 through the mold, multiple bonding teeth 13 are arranged in a linear array. The concavity of the side wall of the steel stator blade 9 and its own serrated shape can make the bonding between the steel stator blade 9 and the rubber stator blade 2 more compact. The operator should ensure that the slurry first contacts the back slurry surface 3 of the blade in the direction of movement, and then contacts the front slurry surface 4 of the blade. With the help of the convex shape of the back slurry surface 3 and the concave shape of the front slurry surface 4, the rubber stator can better To ensure its proper function, the top of the pre-installed sleeve 5 is located above the top of the rubber stator plate 1, and the bottom of the pre-installed sleeve 5 is located below the bottom of the rubber stator plate 1. The operator can install the rubber stator inside the flotation machine through the pre-installed sleeve 5. With the help of the rigid material of the steel stator plate 7, the four pre-installed sleeves 5 can fix the rubber stator relatively stably. After the rubber stator blade 2 and the steel stator blade 9 are bonded to each other, a part of the rubber inside the rubber stator blade 2 can be connected to each other through the rubber connecting hole 12 opened on the side wall of the steel stator blade 9. With the help of this part of the rubber connected inside the rubber connecting hole 12, the bonding strength between the rubber stator blade 2 and the steel stator blade 9 is further improved.
