Description

Technical Field

[0001] This utility model belongs to the field of flotation machine technology, specifically relating to a flotation machine pulp uniform feeding mechanism. Background Technology

[0002] A flotation machine, short for flotation mineral processing machine, is a mechanical device used to complete the flotation process. Its working principle involves injecting air or other gases into a stirred tank, generating a large number of tiny bubbles. These bubbles contact and adhere to the surface of ore particles, causing the particles to decrease in density and float, thus achieving the flotation effect. Flotation machines utilize the difference in affinity between materials and air bubbles to effectively separate materials of different densities, colors, and shapes, thereby improving ore grade and recovery rate.

[0003] Currently, flotation machines on the market are prone to overfeeding of slurry at one time. Overfeeding increases the burden on the internal components of the flotation machine, and the ore in the slurry is prone to accumulate in the conveying pipe, causing blockage. In response to this, this application proposes a uniform slurry feeding mechanism for flotation machines. Utility Model Content

[0004] The purpose of this invention is to provide a uniform feeding mechanism for flotation machine slurry in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A uniform feeding mechanism for flotation machine slurry includes a feed box and a uniform feeding component installed inside a feed cylindrical shell. The feed box includes a feed hopper, a feed cylindrical shell fixed at the bottom of the feed hopper, and a feed hose fixed at the bottom of the feed cylindrical shell. The uniform feeding component includes a rotating rod rotatably disposed inside the feed cylindrical shell and coaxially therewith, and several pusher plates disposed outside the rotating rod for dividing and agitating the slurry inside the feed cylindrical shell.

[0007] The push plate component includes several fixed sleeves fixedly disposed on the side wall of the rotating rod and arranged in a circumferential array, a counterweight plate slidably disposed in one end of the fixed sleeve, and a wear-resistant block fixedly disposed in one end of the counterweight plate for scraping off the adhering material on the inner wall of the feed shell after the rotating rod rotates. The feed hose is provided with a striking mechanism for being pushed by the push plate component after rotation to strike the feed hose and generate vibration.

[0008] As a further optimization of this utility model, a motor for driving the rotating rod to rotate is fixedly installed at the center of one side of the feeding shell.

[0009] As a further optimization of this utility model, a sliding groove is provided in one end of the fixed sleeve plate, and one end of the counterweight plate is slidably connected in the sliding groove of the fixed sleeve plate.

[0010] As a further optimization of this utility model, a return spring is fixedly provided between the groove of the fixed sleeve plate and one end of the counterweight plate.

[0011] As a further optimization of this utility model, a bearing rod is rotatably provided inside the top end of the feed hose, and a vertical plumb line is rotatably provided on the outer wall of the bearing rod.

[0012] As a further optimization of this utility model, the striking mechanism includes a small striking block fixedly disposed at the top of the vertical rod and in contact with one side of the wear-resistant block, and a large striking block fixedly disposed at the bottom of the vertical rod.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The rotation of the rotating rod will drive several pusher plates to rotate accordingly. These pusher plates can divide the inside of the feed shell. Through the slow rotation and flipping of the pusher plates, the slurry can be quantitatively and evenly fed into the flotation machine, avoiding the flotation machine from being clogged due to excessive feeding at one time. In addition, the wear-resistant blocks scraping the inside of the feed shell and the knocking mechanism knocking the feed tube make it less likely for the feed box to become clogged, thus ensuring the uniformity of the feed to the flotation machine.

[0015] 2. The motor drives the push plate to rotate. After the push plate rotates, it uses wear-resistant blocks to scrape off the mineral material adhering to the inner wall of the feed shell. The elasticity of the spring keeps the wear-resistant blocks pressed against the inner wall of the feed shell, preventing gaps from forming between the wear-resistant blocks and the feed shell due to wear, thus extending the service life of the wear-resistant blocks. After the wear-resistant blocks rotate, they push the large and small striking blocks, causing the vertical rod to rotate. The large striking block then strikes the feed hose to generate vibration, making it less likely for the feed hose to become clogged. Attached Figure Description

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example

[0022] like Figure 1-3 As shown, the flotation machine slurry uniform feeding mechanism includes a feed box and a uniform feeding component. The feed box includes a feed hopper 1, a feed cylindrical shell 11 fixedly installed at the bottom of the feed hopper 1, and a feed hose 12 fixedly installed at the bottom of the feed cylindrical shell 11. The operator can install the feed cylindrical shell 11 on the outside of the flotation machine and align the feed hose 12 with the feed inlet of the flotation machine, and then feed the slurry into the feed hopper 1. The feed box feeds the flotation machine. The feed cylindrical shell 11 can connect the feed hopper 1 and the feed hose 12.

[0023] like Figure 1-3 As shown, the uniform feeding assembly is installed inside the feed shell 11. The uniform feeding assembly includes a rotating rod 3 rotatably disposed inside the feed shell 11 and coaxially arranged, and several pusher plates disposed outside the rotating rod 3 for separating and agitating the slurry inside the feed shell 11. A motor 35 for driving the rotating rod 3 to rotate is fixedly installed at the center of one side of the feed shell 11. The output end of the motor 35 is fixedly connected to one end of the rotating rod 3. After the motor 35 runs, it will drive the rotating rod 3 and the pusher plates to rotate. The pusher plates can separate the inside of the feed shell 11, so that multiple quantitative storage spaces for the slurry can be formed between the pusher plates and the feed shell 11. Then, through the slow rotation and agitation of the pusher plates, the slurry can be quantitatively and uniformly fed into the flotation machine, avoiding the flotation machine from being easily blocked due to excessive feeding at one time.

[0024] like Figure 2-3 As shown, the pusher plate includes several fixed sleeve plates 31 fixedly mounted on the side wall of the rotating rod 3 and arranged in a circumferential array, a counterweight plate 33 slidably mounted in one end of the fixed sleeve plate 31, and a wear-resistant block 34 fixedly mounted in one end of the counterweight plate 33 for scraping off the adhering material from the inner wall of the feed shell 11 after the rotating rod 3 rotates. A return spring 36 is fixedly mounted in the groove 32 of the fixed sleeve plate 31 and between it and one end of the counterweight plate 33. The fixed sleeve plate 31 can move the counterweight plate 33 through the groove 32. The connection and limiting are made so that the counterweight plate 33 can slide on the fixed sleeve plate 31. The return spring 36 can connect the fixed sleeve plate 31 and the counterweight plate 33, and the return spring 36 can push the counterweight plate 33 towards the inner wall of the feed shell 11 under its own elastic force. The two sides of the fixed sleeve plate 31 and the counterweight plate 33 respectively abut against the two sides of the inner wall of the feed shell 11, so that several push plate parts can form multiple quantitative storage spaces for slurry in the feed shell 11.

[0025] The push plate can be driven to rotate by the motor 35. After the push plate rotates, the wear-resistant block 34 will scrape off the mineral material attached to the inner wall of the feed shell 11. The spring force of the return spring 36 will make the counterweight plate 33, which slides in the fixed sleeve plate 31, keep the wear-resistant block 34 against the inner wall of the feed shell 11. This will prevent the wear-resistant block 34 from having a gap due to wear and thus prevent it from continuing to scrape the wall, thereby extending the service life of the wear-resistant block 34.

[0026] like Figure 2-3 As shown, the feed hose 12 is provided with a striking mechanism for vibrating by being pushed by a rotating push plate. A bearing rod 2 is rotatably provided inside the top of the feed hose 12, and a vertical plumb line 21 is rotatably provided on the outer wall of the bearing rod 2. The striking mechanism includes a small striking block 22 fixedly provided at the top of the vertical plumb line 21 and in cooperation with the wear-resistant block 34, and a large striking block 23 fixedly provided at the bottom of the vertical plumb line 21. The bearing rod 2 can move between the feed hose 12 and the vertical plumb line 21. Since the volume and weight of the large striking block 23 at the bottom of the vertical plumb line 21 are greater than those of the small striking block 22 at the top of the vertical plumb line 21, the vertical plumb line 21 can remain vertical inside the feed hose 12 before being struck.

[0027] After the rotating rod 3 rotates, it will drive the wear-resistant block 34 and other components to rotate as well. The rotated wear-resistant block 34 will contact and push the small striking block 22, thereby causing the vertical rod 21 to tilt and rotate. The large striking block 23 will then strike the feed hose 12 to generate vibration. The vibration will prevent the feed hose 12 from getting clogged, thus ensuring the normal operation of the feeding mechanism.

[0028] It should be noted that, in use, the operator can install the feed shell 11 on the outside of the flotation machine and align the feed hose 12 with the feed inlet of the flotation machine, and then feed the slurry into the feed hopper 1, which will feed the flotation machine.

[0029] At the same time, the motor 35 is turned on, and the motor 35 drives the pusher plate to rotate. The pusher plate can divide the inside of the feed shell 11, so that multiple quantitative storage spaces for slurry can be formed between the pusher plate and the feed shell 11. Then, through the slow rotation and flipping of the pusher plate, the slurry can be quantitatively and evenly fed into the flotation machine, avoiding the flotation machine from being blocked due to excessive feeding at one time.

[0030] After the push plate rotates, the wear-resistant block 34 will scrape off the mineral material attached to the inner wall of the feed shell 11. The spring force of the return spring 36 will ensure that the counterweight plate 33, which slides in the fixed sleeve plate 31, keeps the wear-resistant block 34 against the inner wall of the feed shell 11. This will prevent the wear-resistant block 34 from having a gap due to wear and thus continue scraping the wall, thereby extending the service life of the wear-resistant block 34.

[0031] Furthermore, the rotated wear-resistant block 34 will contact and push the small striking block 22, thereby causing the vertical plumb bar 21 to tilt and rotate, so as to use the large striking block 23 to strike the feed hose 12 to generate vibration. The vibration makes the feed hose 12 less prone to blockage, thus ensuring the normal use of the feeding mechanism.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
