Description

Technical Field

[0001] This utility model belongs to the field of mineral processing technology, specifically, it relates to a high-frequency vibrating screening device for zirconium-titanium ore beneficiation. Background Technology

[0002] In the process of zirconium-titanium ore beneficiation, the screening stage is crucial for particle size classification. High-quality screening not only improves the efficiency of subsequent beneficiation operations, but also directly affects the purity and recovery rate of the final product. With the development of mining technology, higher requirements have been placed on the processing capacity, classification accuracy and stability of zirconium-titanium ore screening equipment.

[0003] However, in practical applications, existing screening equipment often suffers from the phenomenon of large particles being entrained with fine particles, and insufficient screening of fine particles, which increases the burden on subsequent separation processes and makes it difficult to meet the standards for concentrate purity and recovery rate.

[0004] In addition, existing screening devices mostly adopt intermittent operation mode for feeding and discharging, which requires frequent shutdowns to pick up and put away materials. This not only reduces production efficiency but also increases labor costs and equipment wear and tear, and cannot meet the needs of large-scale and continuous production in modern mines. Therefore, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a high-frequency vibrating screening device for zirconium-titanium ore beneficiation that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a high-frequency vibrating screening device for zirconium-titanium ore beneficiation, including a screening box, and further including: multiple inclined screening plates, which are fixedly connected in a staggered manner from top to bottom within the screening box; flow chambers are symmetrically opened on both sides of the screening box; a first guide plate is inclinedly fixedly connected within the screening box and located below each of the screening plates, and an opening communicating with the flow chamber is opened on the side wall of the screening box fixedly connected to the first guide plate; a feed pipe is fixedly connected to the feed inlet at the upper end of the screening box; a first discharge port is opened on one side of the lower end of the screening box; a second discharge port is opened at the lower end of the flow chamber; a shock-absorbing base on which the screening box is mounted; and a vibrator installed at the bottom of the screening box.

[0007] Furthermore, the shock-absorbing base includes a base plate and two sets of shock absorbers. The two sets of shock absorbers are symmetrically arranged between the base plate and the screening box, and the two ends of the shock absorbers are rotatably connected to the base plate and the screening box, respectively.

[0008] Furthermore, the vibrator includes a support plate, a rotating shaft, an eccentric wheel, and a motor. The support plates are symmetrically and fixedly connected to the bottom of the screening box. The rotating shaft is rotatably connected between the two support plates. The eccentric wheel is fixedly connected to the rotating shaft. The motor is fixedly connected to one of the support plates, and its output end is fixedly connected to the end adjacent to the rotating shaft.

[0009] To facilitate dust suppression, the system further includes a mounting plate. A dust filter cover is detachably connected to the lower end of the mounting plate via threads. The mounting plate has a through-hole that communicates with the dust filter cover. An air pump is fixedly connected to the upper end of the screening box near the mounting plate. The air pump's suction end is connected to the dust discharge port of the screening box via a suction pipe, and the air pump's outlet end is connected to the through-hole of the mounting plate.

[0010] To facilitate the flow of fine particulate materials, a second guide plate is further fixedly connected inside the second discharge port.

[0011] To facilitate observation of the interior of the screening box, an installation port is provided on the screening box, and an observation window is fixedly connected to the installation port.

[0012] After adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: This utility model achieves efficient and continuous screening of zirconium-titanium ore materials through the consistent screen hole design of multi-layer screening plates and high-frequency vibration. Small particles pass through the screen quickly when they first come into contact with the screen surface, while large particles are repeatedly purified by multi-stage screening plates and finally accurately separated through the first discharge port and the second discharge port, which effectively improves the screening efficiency. In addition, by continuously feeding materials into the feed pipe, the device can operate continuously without stopping to pick up or drop materials, which greatly improves the continuity of production, reduces labor costs and equipment wear and tear, and is especially suitable for the high-efficiency production needs of large-scale zirconium-titanium ore processing enterprises.

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

[0021] Example 1: Refer to Figures 1-4 A high-frequency vibrating screening device for zirconium-titanium ore beneficiation includes a screening box 1, and further includes: multiple inclined screening plates 2, which are fixedly connected in a staggered manner from top to bottom within the screening box 1; flow chambers 103 are symmetrically opened on both sides of the screening box 1; a first guide plate 201 is inclinedly fixedly connected within the screening box 1 and located below each screening plate 2, and an opening 107 connected to the flow chamber 103 is opened on the side wall of the screening box 1 that is fixedly connected to the first guide plate 201; a feed pipe 101 is fixedly connected to the feed inlet at the upper end of the screening box 1; a first discharge port 102 is opened on one side of the lower end of the screening box 1; a second discharge port 104 is opened at the lower end of the flow chamber 103; a shock-absorbing base on which the screening box 1 is mounted; and a vibrator installed at the bottom of the screening box 1.

[0022] The shock-absorbing base includes a base plate 5 and two sets of shock absorbers 501. The two sets of shock absorbers 501 are symmetrically arranged between the base plate 5 and the screening box 1. The two ends of the shock absorbers 501 are rotatably connected to the base plate 5 and the screening box 1, respectively.

[0023] The vibrator includes a support plate 3, a rotating shaft 301, an eccentric wheel 302, and a motor 303. The support plates 3 are symmetrically and fixedly connected to the bottom of the screening box 1. The rotating shaft 301 is rotatably connected between the two support plates 3. The eccentric wheel 302 is fixedly connected to the rotating shaft 301. The motor 303 is fixedly connected to one of the support plates 3, and its output end is fixedly connected to the end adjacent to the rotating shaft 301.

[0024] When the zirconium-titanium ore needs to be screened, the pre-treated zirconium-titanium ore is first fed into the screening box 1 through the feed pipe 101 and falls onto the uppermost inclined screening plate 2. The vibrator (motor 303 drives the eccentric wheel 302 to rotate) generates high-frequency vibration, causing the screening plate 2 to vibrate rapidly. Since all the screening plates 2 have the same screen hole size (e.g., 0.5mm), small particles smaller than the screen hole (e.g., fine zircon sand particles) are dispersed by the vibration and quickly pass through the screen to the lower first guide plate 201, while large particles larger than the screen hole (e.g., zirconium-titanium ore blocks) slide down the screening plate 2 to the lower end.

[0025] After large particles slide to the lower end of the screening plate 2, they continue to bounce under the action of vibration, repeatedly contacting the screen surface for secondary screening. If the particles are dispersed into smaller particles due to collision, they can continue to pass through the screen. Large particles that do not pass through the screen fall into the lower screening plate 2, repeating the sliding + screening process. In this stage, the multi-layer screening plates 2 form a screening mechanism for the material on the screen. Large particles are further purified each time they pass through a layer of screening plates 2, while small particles continuously pass through the screen to the first guide plate 201.

[0026] Small particles passing through the screen are guided by the first guide plate 201 and enter the flow chamber 103 through the through port 107. Finally, they are discharged from the second discharge port 104. After being repeatedly screened by the multi-layer screening plate 2, the remaining large particles slide to the lower end of the screening box 1 and are discharged from the first discharge port 102. Thus, the zirconium-titanium ore is accurately separated according to particle size. Small particles (such as below 0.5mm) and large particles (such as above 0.5mm) enter the subsequent separation process respectively. By continuously feeding materials into the feed pipe 101, the zirconium-titanium ore can be continuously screened. The whole process does not require stopping the machine to pick up or drop materials.

[0027] Through the consistent screen aperture design of the multi-layer screening plate 2 and the coordination of high-frequency vibration, this device achieves efficient and continuous screening of zirconium-titanium ore. Small particles such as <0.5mm pass through the screen quickly upon first contact with the screen surface, while large particles are repeatedly purified by the multi-stage screening plate 2 and finally accurately separated through the first discharge port 102 and the second discharge port 104, effectively improving screening efficiency. Furthermore, by continuously feeding materials into the feed pipe 101, the device can operate continuously without stopping to pick up or drop materials, greatly improving the continuity of production, reducing labor costs and equipment wear and tear, and is especially suitable for the high-efficiency production needs of large-scale zirconium-titanium ore processing enterprises.

[0028] Example 2: Refer to Figures 1-4A high-frequency vibrating screening device for zirconium-titanium ore beneficiation is basically the same as that in Example 1, but further includes a mounting plate 4. The lower end of the mounting plate 4 is detachably connected to a dust filter 401 by a thread. The mounting plate 4 has a through-hole that communicates with the dust filter 401. An air pump 403 is fixedly connected to the upper end of the screening box 1 near the mounting plate 4. The air pump 403's suction end is connected to the dust discharge port of the screening box 1 through a suction pipe 402, and the air pump 403's outlet end is connected to the through-hole of the mounting plate 4.

[0029] This section, through the combined design of air pump 403, air extraction pipe 402, mounting plate 4, and dust filter hood 401, effectively solves the dust pollution problem during the screening process and improves the environmental performance and operational stability of the equipment. Air pump 403 extracts the dust generated in the screening box 1 through air extraction pipe 402, preventing dust from overflowing into the working environment, protecting the occupational health of operators, and meeting environmental protection production requirements. The extracted dust enters the dust filter hood 401 with the airflow, and after filtration, gas-solid separation is achieved, and clean gas is discharged. The trapped dust can be cleaned centrally by disassembling the dust filter hood 401, which is convenient to operate and has low maintenance costs. In addition, the detachable dust filter hood 401 is connected to the mounting plate 4 by threads, which is convenient for quick replacement and extends the service life of the equipment. The forced dust extraction method of air pump 403 can also improve the airflow environment in the screening box 1, prevent dust accumulation from affecting screening efficiency, ensure continuous and stable operation of the equipment, and achieve the dual goals of environmental protection and high-efficiency production.

[0030] Furthermore, the dust filter hood 401 can slow down the clogging speed of dust under the action of high-frequency vibration, so that more dust can be stored and the frequency of disassembly and cleaning can be reduced.

[0031] Example 3: Reference Figures 1-4 A high-frequency vibrating screening device for zirconium-titanium ore sorting is basically the same as that in Example 2, but with a further improvement: a second guide plate 105 is fixedly connected inside the second discharge port 104. The second guide plate 105 installed inside the second discharge port 104 can significantly optimize the discharge process of fine particles, improve the overall sorting efficiency and equipment operation stability. The second guide plate 105 can guide and buffer the fine particles collected in the flow chamber 103, avoiding splashing of materials due to excessive falling speed and impact force, reducing material loss and workshop pollution. At the same time, the inclined design of the guide plate can make the material discharge evenly and smoothly, preventing blockage or material accumulation at the discharge port, ensuring the continuity of the screening process. In addition, by reasonably designing the angle and shape of the guide plate, it can also be seamlessly connected with subsequent material collection and transfer equipment (such as belt conveyors and storage silos), improving the automation and coordination of the production line, reducing the cost of manual intervention, and providing a guarantee for the efficient and stable operation of zirconium-titanium ore sorting.

[0032] The screening box 1 has an installation port, and an observation window 106 is fixedly connected to the installation port. The observation window 106 on the screening box 1 provides an intuitive and convenient solution for equipment operation monitoring and fault diagnosis, which significantly improves production management efficiency and equipment reliability. Through the observation window 106, the operator can view the screening status of the material inside the screening box 1 in real time, including the distribution of the material on the screening plate 2, the screening efficiency, whether there is screen hole blockage or material accumulation, etc., and promptly detect abnormalities and adjust screening parameters (such as vibration frequency and feed speed) to avoid a decrease in screening efficiency or equipment failure due to improper parameters. In addition, the observation window 106 can also assist in equipment maintenance. Maintenance personnel can quickly confirm the wear degree of internal components (such as screening plate 2 and first guide plate 201) without frequent disassembly of the box, reducing downtime and maintenance costs, and improving the level of refined management of zirconium-titanium ore screening operations.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
