Description

Technical Field

[0001] The utility model belongs to the technical field of fluorite ore processing, and specifically relates to a mechanical processing and screening device for smelting-grade fluorite ore. Background Art

[0002] Fluorite has the characteristics of reducing the melting point of refractory substances, promoting the flow of slag, enabling good separation of slag and metal, desulfurizing and dephosphorizing during the smelting process, and enhancing the forgeability and tensile strength of metals. Therefore, it is widely used as a flux in iron and steel smelting, ferroalloy production, cupola process, and non-ferrous metal smelting.

[0003] After the fluorite ore is mined, it needs to be sorted according to grade. After sorting out high-quality fluorite, it can be further processed. During the processing, the fluorite ore needs to be crushed and then classified according to particle size.

[0004] The screening of fluorite ore needs to determine the screening equipment according to the situation. For example, if the raw ore has a large amount of mud and a serious bonding degree, a drum screen is used for screening to reduce the situation of screen hole blockage. Adding water to the drum screen for screening can also play a role in ore washing. If the raw ore does not contain mud and is a rock ore with a very low water content, a circular vibrating screen can be used for efficient screening operations.

[0005] When using a circular vibrating screen to screen fluorite ore with different particle size grades mixed together, in order to ensure the sufficiency of screening fluorite ore particles, generally, the inclined screen plate is designed to be longer, so as to improve the sufficiency of screening fluorite ore particles. With this design, although the sufficiency of screening fluorite ore particles can be ensured, it undoubtedly increases the floor area of the equipment. Therefore, when using a circular vibrating screen to screen fluorite ore particles, the selection of the site is relatively limited. In view of this, the present utility model is specially proposed. Summary of the Utility Model

[0006] The technical problem to be solved by the present utility model is to overcome the deficiencies of the prior art and provide a mechanical processing and screening device for smelting-grade fluorite ore that can overcome or at least partially solve the above problems.

[0008] Further, the oil transmission mechanism includes an electric telescopic rod, an oil transmission cylinder, and a piston rod with a piston. The oil transmission cylinder is fixedly connected to the position of the base close to the hydraulic cylinder. A through port is provided between the hydraulic cylinder and the oil transmission cylinder. The piston rod is slidably connected within the oil transmission cylinder. The electric telescopic rod is fixedly connected to the side of the base close to the column through a support. The telescopic end of the electric telescopic rod is fixedly connected to the two piston rods through a push plate.

[0009] Further, the vibration mechanism includes a housing, a rotating shaft, a motor, and an eccentric block. The housing is fixedly connected to the middle position of the bottom of the concave frame plate. The rotating shaft is rotatably connected within the housing. The motor is installed on one side of the housing, and the output end is fixedly connected to the adjacent end of the rotating shaft. The eccentric blocks are equidistantly fixedly connected to the rotating shaft.

[0010] To facilitate improving the service life of the telescopic spring, still further, a limit telescopic guide rod is fixedly connected between the mounting plate and the first hinge seat and the second hinge seat, and the telescopic spring is sleeved outside the limit telescopic guide rod.

[0011] To facilitate different material particles to roll to different positions when leaving the device for separate collection, further, the sides of the first sieve plate and the second sieve plate away from the baffle extend out of the concave frame plate, and the length of the first sieve plate is longer than that of the second sieve plate.

[0012] To facilitate improving the service life of the first sieve plate and the second sieve plate, further, a plurality of support rods are equidistantly fixedly connected to the bottom of the first sieve plate and the second sieve plate within the concave frame plate.

[0013] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art: By the combined use of components such as a hydraulic cylinder, a piston column, a mounting plate, a first hinge seat, a second hinge seat, a T-shaped chute, a T-shaped block, and a conveying mechanism, compared with the method of using a circular vibrating screen to vibrate and screen material particles in the prior art, when screening materials of different particle size grades mixed together, not only can the material particles be vibrated, but also the first sieve plate and the second sieve plate can be controlled to rotate reciprocally up and down, so that the material particles can roll back and forth on the first sieve plate and the second sieve plate, effectively ensuring the sufficiency of screening the material particles.

Specific Embodiments

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not intended to limit the scope of the present utility model.

[0021] Embodiment 1:

[0022] Referring to Figures 1 - 3, a mechanical processing and screening device for metallurgical-grade fluorite ore, including a base 1, and further including: a concave frame plate 2 with baffles 201 provided on one side, arranged above the base 1; struts 101, symmetrically and fixedly connected to one side of the base 1; hydraulic cylinders 102, symmetrically and fixedly connected to the side of the base 1 away from the struts 101; piston columns 103 with pistons, slidably connected in the hydraulic cylinders 102; an oil transmission mechanism for injecting and discharging hydraulic oil into the hydraulic cylinders 102, installed on the base 1; a mounting plate 104, fixedly connected to the upper ends of the struts 101 and the piston columns 103; a telescopic spring 105, fixedly connected to the mounting plate 104; the telescopic spring 105 on one side of the strut 101 is rotatably connected to the concave frame plate 2 through a first hinge seat 107; the upper end of the telescopic spring 105 on one side of the hydraulic cylinder 102 is rotatably connected to a T-shaped block 109 through a second hinge seat 108; a T-shaped chute 205 is opened at the bottom of the concave frame plate 2 near the T-shaped block 109, and the T-shaped block 109 slides in the T-shaped chute 205; a first sieve plate 202 and a second sieve plate 203 are fixedly connected in the concave frame plate 2 from top to bottom in sequence, and the aperture diameter of the sieve holes of the first sieve plate 202 is larger than that of the second sieve plate 203; a vibration mechanism for controlling the concave frame plate 2 to vibrate is installed at the bottom of the concave frame plate 2.

[0023] The oil transmission mechanism includes an electric telescopic rod 3, an oil transmission cylinder 302 and a piston rod 303 with a piston. The oil transmission cylinder 302 is fixedly connected to the position of the base 1 close to the hydraulic cylinder 102. A mutually penetrating through-port is opened between the hydraulic cylinder 102 and the oil transmission cylinder 302. The piston rod 303 is slidably connected in the oil transmission cylinder 302. The electric telescopic rod 3 is fixedly connected to the side of the base 1 close to the strut 101 through a support. The telescopic end of the electric telescopic rod 3 is fixedly connected to the two piston rods 303 through a push plate 301.

[0024] The vibration mechanism includes a housing 4, a rotating shaft 401, a motor 402 and an eccentric block 403. The housing 4 is fixedly connected to the middle position at the bottom of the concave frame plate 2. The rotating shaft 401 is rotatably connected in the housing 4. The motor 402 is installed on one side of the housing 4, and the output end is fixedly connected to the adjacent end of the rotating shaft 401. The eccentric blocks 403 are equidistantly fixedly connected to the rotating shaft 401.

[0025] When the fluorite ore needs to be classified and screened after being crushed, the motor 402 can be started at this time. The motor 402 will drive the eccentric block 403 to rotate at high speed through the rotating shaft 401. Then, with the cooperation of the telescopic spring 105, an exciting force can be generated on the concave frame plate 2. Then, the staff can pour the materials of different particle size grades mixed together onto the first sieve plate 202. Then, the materials will be continuously tossed and flipped on the first sieve plate 202 under the action of the exciting force. The material particles smaller than the sieve holes of the first sieve plate 202 will fall onto the second sieve plate 203, and the material particles smaller than the sieve holes of the second sieve plate 203 will fall onto the concave frame plate 2.

[0026] When pouring the materials onto the first sieve plate 202, the electric telescopic rod 3 can be started to stretch back and forth. The electric telescopic rod 3 will drive the piston on the piston rod 303 to move back and forth in the oil delivery cylinder 302 through the push plate 301. When the piston on the piston rod 303 pushes the hydraulic oil in the oil delivery cylinder 302 into the hydraulic cylinder 102, the piston column 103 with the piston will move upward at this time, so as to drive one side of the blanking end of the concave frame plate 2 to tilt upward. When the piston on the piston rod 303 moves back, the hydraulic oil in the hydraulic cylinder 102 will flow back into the oil delivery cylinder 302 at this time, and then one side of the blanking end of the concave frame plate 2 will tilt downward under the action of its own gravity. By controlling the reciprocating movement of the piston rod 303 in the oil delivery cylinder 302, the blanking end of the concave frame plate 2 can be controlled to move up and down reciprocally along the first hinge seat 107. Then, the material particles can roll back and forth on the first sieve plate 202 and the second sieve plate 203, effectively ensuring the sufficiency of screening the material particles. When the screening of the material particles is completed, at this time, control the blanking end of the concave frame plate 2 to tilt downward, and then the screened material particles will roll out of the device along the inclined surfaces of the concave frame plate 2, the first sieve plate 202, and the second sieve plate 203 under the action of the exciting force.

[0027] Example 2:

[0028] Refer to Figures 1 - 3 For the mechanical processing and screening device of smelting-grade fluorite ore, it is basically the same as that in Example 1. Furthermore: A limit telescopic guide rod 106 is fixedly connected between the mounting plate 104 and the first hinge seat 107 and the second hinge seat 108. The telescopic spring 105 is sleeved outside the limit telescopic guide rod 106. Through the setting of the limit telescopic guide rod 106, when the telescopic spring 105 buffers the vibration force transmitted to the mounting plate 104, the telescopic spring 105 can only be telescoped in the up and down directions, avoiding the inclined deformation of the telescopic spring 105 due to irregular telescopic movement, thereby affecting the stability of the concave frame plate 2.

[0029] Example 3:

[0030] Refer toFigures 1 - 3 , a mechanical processing and screening device for metallurgical-grade fluorite ore, which is basically the same as that of Embodiment 2. Further, on the sides of the first sieve plate 202 and the second sieve plate 203 away from the baffle plate 201, both extend out of the concave frame plate 2. The length of the first sieve plate 202 is longer than that of the second sieve plate 203. As Figure 1 shown, by making the length of the first sieve plate 202 longer than that of the second sieve plate 203, when it is necessary to make the fluorite roll off from the concave frame plate 2, the first sieve plate 202, and the second sieve plate 203 after the screening of the fluorite is completed, at this time, fluorite of different particle size grades will roll obliquely downward to different positions on the concave frame plate 2, the first sieve plate 202, and the second sieve plate 203. The staff only needs to place a collection box at the corresponding position to complete the collection of fluorite of different particle size grades.

[0031] A plurality of support rods 204 are equally spaced and fixedly connected to the bottom of the first sieve plate 202 and the second sieve plate 203 inside the concave frame plate 2. By arranging a plurality of support rods 204 at the bottom of the first sieve plate 202 and the second sieve plate 203, the first sieve plate 202 and the second sieve plate 203 can be supported, avoiding large-scale deformation of the first sieve plate 202 and the second sieve plate 203, and effectively improving the service life of the first sieve plate 202 and the second sieve plate 203.

[0032] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention.
