Description

Technical Field

[0001] This utility model relates to the field of mining technology, specifically a wet particle size screening machine for mining. Background Technology

[0002] Grading is the most basic step in the mineral processing engineering. Grading involves screening and filtering the products from the grinding process according to the particle size. Products that do not meet the requirements are returned to the grinding process for repeated grinding, while the mineral particles that meet the requirements are entered into other processes. In some mines, wet particle size analyzers are used to classify and screen the mineral particles in the slurry according to their particle size by setting up multi-stage filter plates.

[0003] The existing patent authorization announcement number CN 219745503 U discloses a wet particle size screening machine for mining. The driven shaft drives the filter plate to rotate. The first filter plate, the second filter plate and the bottom plate drive the corresponding vortex plate to rotate. The wet mineral particles are screened by particle size step by step through the first filter plate and the second filter plate. The screened wet mineral particles are collected through the corresponding discharge port under the action of centrifugal force. The driven shaft drives the filter plate to move vertically up and down, thereby vertically shaking the wet mineral particles inside the device and improving the screening efficiency of the device for wet mineral particles.

[0004] In the aforementioned patent, mineral particles are screened through a first filter plate and a second filter plate before being discharged. During use, some mineral particles are easily stuck in the screen holes of the first and second filter plates, causing blockage. The screening cylinder is inconvenient to open, making it difficult to quickly clean the first and second filter plates, thus reducing the screening efficiency. Utility Model Content

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model provides a technical solution: a wet particle size screening machine for mining, including a screening frame 1, with a screen plate 2 and a screen plate 3 staggered vertically arranged on the inner side of the screening frame 1, a support 4 movably installed at the bottom of the screening frame 1, a washing assembly 5 on the left side of the screening frame 1, a vibrating motor box 6 fixedly installed at the bottom of the screening frame 1, and a vibrating motor (model YZS-10-2) installed inside the vibrating motor box 6. Moving grooves 11 located below the screen plate 2 and screen plate 3 are respectively opened on the left and right sides of the screening frame 1. The washing assembly 5 includes a guide frame 51 fixedly installed on the left side of the screening frame 1, a reciprocating screw 52 rotatably installed inside the guide frame 51, a sliding block 53 movably installed outside the reciprocating screw 52, ​​a motor 54 connected to the reciprocating screw 52 fixedly installed at the rear side of the guide frame 51, and a diversion pipe 55 fixedly installed inside the sliding block 53. Two flushing pipes 56 are fixedly installed at the ends of the 5, located below the first screen plate 2 and the second screen plate 3 respectively. The outside of the diversion pipe 55 is fixedly connected to the water inlet pipe 58. Water is transported to the diversion pipe 55 through the water inlet pipe 58, and then the water flow is evenly distributed to the flushing pipes 56 located below the first screen plate 2 and the second screen plate 3. The water is sprayed out in the form of high pressure. The strong water pressure flushes out the mineral particles blocked in the holes of the first screen plate 2 and the second screen plate 3, achieving the cleaning effect. The motor 54 can be a Y2-112M-4. The motor 54 drives the reciprocating screw 52 to rotate, so that the sliding block 53 moves along the predetermined trajectory. The sliding block 53 pushes the flushing pipe 56 to move in the moving groove 11, so that the flushing pipe 56 can move along the length direction of the first screen plate 2 and the second screen plate 3, pushing the mineral particles flushed out by the water to the front side for discharge, improving the efficiency of the cleaning work and reducing the need for manual intervention.

[0024] The other end of each of the two rinsing pipes 56 is fixedly connected to a slide block 57 that is locked in the moving groove 11. The slide block 57 is tightly fitted to the inner wall of the moving groove 11. Rollers are installed in the slide block 57. During the process of the sliding block 53 driving the rinsing pipe 56 to move, the slide block 57 can provide stable support for the rinsing pipe 56, ensuring that the rinsing pipe 56 is always kept in the correct rinsing position.

[0025] The outside of the flushing pipe 56 is provided with flushing heads that are inclined forward and upward. The flushing heads are evenly distributed along the length of the flushing pipe 56, which enables the high-pressure water flow to accurately impact the lower surface of the screen plate 2 and the screen plate 3, forming an upward impact force. This can efficiently flush away the blocked mineral particles, and can also use the oblique thrust of the water flow to gather the mineral particles in the same direction, making it easier to push them out later.

[0026] A quick connector is provided at the end of the inlet pipe 58 away from the branch pipe 55. The quick connector can be quickly connected to an external high-pressure water source hose for water supply. The quick connector is easy to install and remove, shortens the connection time with the water source pipeline, and improves the flexibility of use and work efficiency.

[0027] The reciprocating screw 52 is arranged in the same direction as the length of the first screen plate 2 and the second screen plate 3. The length of the reciprocating screw 52 is adapted to the length of the first screen plate 2 and the second screen plate 3, ensuring that the rinsing pipe 56 rinsing the lower surface of the first screen plate 2 and the second screen plate 3 is comprehensive and uniform, avoiding rinsing dead corners. The end of the reciprocating screw 52 is rotatably connected to the inner wall of the guide frame 51 through the bearing seat, which improves the reliability of operation and service life.

[0028] Please see Figure 1 , Figure 2 and Figure 5 The inner side of the screening frame 1 is fixedly connected to two staggered retaining rails 12, both of which are located above the moving groove 11. The rear side of the screening frame 1 has an opening corresponding to the two retaining rails 12. Screen plate 1 2 and screen plate 2 3 are respectively locked inside the two retaining rails 12. The rear side of the screening frame 1 is fixedly connected to an ear block 13 that is higher than the two retaining rails 12. The ear block 13 has a pin 14 that is movably installed inside the ear block 13 and is locked inside the screen plate 1 2 and screen plate 2 3. By pulling out the pin 14 inserted in the ear block 13 from the rear of the screening frame 1, the pin 14 is disengaged from the screen plate 1 2 and screen plate 2 3 that pass through it. Then, the screen plate 1 2 and screen plate 2 3 can be pulled backward along the two retaining rails 12. The retaining rails 12 provide a stable guiding function, which can easily realize the disassembly of screen plate 1 2 and screen plate 2 3 and provide convenient conditions for subsequent replacement, making maintenance more efficient and quick.

[0029] The mesh size of sieve plate 23 is larger than that of sieve plate 2, allowing mineral particles to pass through sieve plate 2 first during the screening process. Larger particles are retained, while smaller particles fall through the sieve holes of sieve plate 2 into sieve plate 23 below, where they are further screened. This achieves the grading of materials with different particle sizes, effectively improving screening accuracy and efficiency.

[0030] Working principle: By moving the device to the designated position, the wet mineral particles to be screened are then conveyed to the feed inlet of the screening frame 1 via an external conveying device. The wet mineral particles fall onto screen plate 2. Screen frame 1 is supported by a spring connection to the support 4. By controlling the start of the vibration motor in the vibration motor box 6, the screening frame 1 vibrates. The wet mineral particles on screen plate 2 shake and move forward and downward. During this process, the mineral particles that meet the requirements are screened out and fall onto screen plate 3. The wet mineral particles are screened by screen plate 2 and screen plate 3 and then discharged from the front of the screening frame 1. When screen plate 2 and screen plate 3 are jammed, the particles are removed from the screen frame 1. When the mineral particles are severely clogged, water is pumped into the water inlet pipe 58 through the external water source hose and then transported through the diversion pipe 55 to the flushing pipe 56 below the screen plate 1 and screen plate 2 3. High-pressure water is sprayed from the bottom of the flushing head onto the screen plate 1 and screen plate 2 3 for flushing. The water pressure flushes out the clogged mineral particles. The motor 54 drives the reciprocating screw 52 to rotate, which drives the sliding block 53 to move the flushing pipe 56 in the moving groove 11 along the length of the screen plate 1 and screen plate 2 3. With the vibration of the screen plate 1 and screen plate 2 3, the flushed mineral particles are transported to the front and discharged, which facilitates the cleaning work.

[0031] When sieve plate 2 and sieve plate 3 become worn and need to be replaced after a long period of use, the pin 14 located inside the ear block 13 and penetrating sieve plate 2 and sieve plate 3 can be pulled out from the rear side of the screening frame 1. Then, sieve plate 2 and sieve plate 3 can be pulled backward along the inside of the two retaining rails 12, which facilitates the quick disassembly and replacement of sieve plate 2 and sieve plate 3 and improves the convenience of maintenance. The above is the working process of the whole device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
