Description
Technical Field
[0001] The utility model relates to the technical field of vibrating screens, in particular to a multi-layer screening dual-power vibrating screen structure. Background Art
[0002] The vibrating screen works by utilizing the double rotational vibration generated by the vibrator. Its upper rotating weight causes the screen surface to produce a plane rotation vibration, while the lower rotating weight causes the screen surface to produce a conical rotation vibration. The combined effect causes the screen surface to produce multi-rotation vibration. Its trajectory is a complex spatial curve. The amplitude can be changed by adjusting the exciting force of the upper and lower rotating weights. By adjusting the spatial phase angle of the upper and lower counterweights, the curve shape of the screen surface motion trajectory can be changed, and the motion trajectory of the material on the screen surface can be changed. Among them, the dual-powered multi-layer screening vibrating screen is a screening equipment that uses two sets of special exciters to provide vibration sources. Materials of different particle sizes are graded through multi-layer screens to separate large and small particles and make the finished product uniform. This screening equipment usually has two-layer, three-layer, and four-layer vibrating screens, all of which are called multi-layer vibrating screens. The dual-powered multi-layer screening vibrating screen is installed on the side panels of the screen core through two sets of exciters. When the material enters the screen surface, it forms a parametric vibration mass together with the screen core.
[0003] The inclination angle of the internal sieve plate of the dual-power multi-layer screening vibrating screen is usually fixed at a certain inclination angle. However, in actual use, the inability to adjust the inclination angle of the sieve plate according to the material characteristics and screening requirements may lead to reduced screening efficiency. Different materials require different screening angles to achieve the best screening effect. For materials with different particle size, viscosity or humidity, the fixed sieve plate angle may not provide effective screening. Since it cannot adapt to the screening requirements of different materials, the application scope of the multi-layer screening vibrating screen is limited. The operator cannot flexibly adjust the screen plate angle according to the actual situation, which limits the adaptability of the equipment and the convenience of operation. In view of this, we propose a multi-layer screening dual-power vibrating screen structure. Utility Model Content

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] The vibrating screen works by utilizing the double-rotational vibration generated by the vibrator. Its upper rotating weight causes the screen surface to produce a plane rotation vibration, while the lower rotating weight causes the screen surface to produce a conical rotation vibration. The combined effect causes the screen surface to produce multi-rotation vibration. Its trajectory is a complex spatial curve. The amplitude can be changed by adjusting the exciting force of the upper and lower rotating weights. Adjusting the spatial phase angle of the upper and lower counterweights can change the curve shape of the screen surface motion trajectory and the motion trajectory of the material on the screen surface. Among them, the dual-power multi-layer screening vibrating screen is a screening device that uses two sets of special exciters to provide a vibration source. The materials of different particle sizes are graded through the multi-layer screen, so that the large and small particles are separated and the finished product is uniform. This screening equipment usually has two, three, and four-layer vibrating screens, all of which are called multi-layer vibrating screens. The dual-power multi-layer screening vibrating screen is installed on the side panels of the screen core through two sets of exciters. When the material enters the screen surface, it forms a parametric vibration mass together with the screen core.
[0025] See also Figures 1-6 As shown, this embodiment provides a dual-power vibrating screen structure for multi-layer screening, including a mounting bracket 100 and a processing box 200. The processing box 200 is installed above the mounting bracket 100. Considering that in actual use, the inability to adjust the inclination angle of the screen plate according to the material characteristics and screening requirements may lead to reduced screening efficiency. Different materials require different screening angles to achieve the best screening effect. For materials with different particle sizes, viscosities or humidity, a fixed screen plate angle may not provide effective screening. Since it cannot adapt to the screening requirements of different materials, the multi-layer screening The application scope of the vibrating screen is limited. The operator cannot flexibly adjust the screen plate angle according to the actual situation, which limits the adaptability of the equipment and the convenience of operation. Therefore, the details are as follows: the first screen plate 201, the second screen plate 202 and the third screen plate 203 are installed in sequence from top to bottom in the processing box 200. A support plate 101 is installed on one surface of the mounting bracket 100. The upper surface of the support plate 101 is symmetrically provided with a mounting plate 1010. The top of the mounting plate 1010 is set inside the processing box 200. The surface of the mounting plate 1010 is provided with a track groove 1011, wherein:
[0026] An adjustment assembly 400 is provided inside the track groove 1011 , and the adjustment assembly 400 is used to adjust the inclination angles of the first sieve plate 201 , the second sieve plate 202 and the third sieve plate 203 .
[0027] The improvement of this embodiment is that:
[0028] By utilizing the adjustment component 400, the operator can flexibly adjust the inclination angles of the first sieve plate 201, the second sieve plate 202 and the third sieve plate 203 according to actual production conditions, thereby improving the adaptability and operational convenience of the equipment; different materials have different fluidity and screening difficulties. By adjusting the inclination angles of the sieve plates, the screening effect can be optimized according to the characteristics of the material and the screening requirements, and the residence time of the material on the screen can be reduced, thereby improving the screening efficiency.
[0029] Specifically, the adjustment assembly 400 includes a threaded rod 401 and a plurality of sliders 402, and the plurality of sliders 402 are threadedly engaged with the outer wall of the threaded rod 401, wherein: the plurality of sliders 402 correspond to the positions of the first sieve plate 201, the second sieve plate 202 and the third sieve plate 203 respectively in sequence, and a fixing seat 4020 is installed on the outer wall of the slider 402, and the fixing seat 4020 is set as a U-shaped structure. The fixing seat 4020 is connected to a rotating shaft 4021 for rotating relative to the two inner walls. A limiting block 4022 is set on the outer wall of the rotating shaft 4021, and the plurality of limiting blocks 4022 are connected to the first sieve plate 201, the second sieve plate 202 and the third sieve plate 203 respectively in sequence;
[0030] Due to the limiting effect of the track groove 1011 on the slider 402, the precise control of the position of the slider 402 is achieved through the threaded cooperation between the threaded rod 401 and the slider 402. When the threaded rod 401 rotates, the slider 402 will move along the threaded rod 401, thereby driving the fixed seat 4020 and the rotating shaft 4021 to move together. The design of the fixed seat 4020 enables the rotating shaft 4021 to rotate together between the two inner walls. When the rotating shaft 4021 rotates, it will drive the limit block 4022 to rotate together, thereby changing the corresponding inclination angles of the first screen plate 201, the second screen plate 202 and the third screen plate 203.
[0031] In order to allow materials of different pore sizes to be discharged in sequence during the screening process, a discharge box 300 is installed at the end of the processing box 200, and the discharge box 300 includes a first discharge port 301, a second discharge port 302 and a third discharge port 303, wherein: the first discharge port 301 is connected to the area above the first sieve plate 201, the second discharge port 302 is connected to the area between the second sieve plate 202 and the first sieve plate 201, the third discharge port 303 is connected to the area between the third sieve plate 203 and the second sieve plate 202, and a fourth discharge port 204 is installed at the bottom of the processing box 200; by setting multiple discharge ports, materials of different pore sizes can be screened on sieve plates of different levels, and then discharged through corresponding discharge ports. Different discharge ports correspond to different sieve plate areas, which can effectively avoid the mixing of materials of different particle sizes, ensure the purity of the screened materials, and improve the overall screening efficiency.
[0032] In order to facilitate the control of the rotation of the threaded rod 401 and drive the slider 402 to slide on its outer wall, the bottom ends of the two threaded rods 401 are both penetrated through the track groove 1011 to the bottom of the support plate 101, and a driving component 500 is installed under the support plate 101. The driving component 500 includes a set of pulleys 501, and the two pulleys 501 are respectively installed on the outer wall of the bottom ends of the two threaded rods 401. A driving belt 5010 is commonly connected between the outer walls of the two pulleys 501. The driving component 500 also includes a rotating handle 502, and the rotating handle 502 is connected to the bottom of the two threaded rods 401. A threaded rod 401 is fixedly connected at the bottom end, and one of the threaded rods 401 is rotated by rotating the handle 502. The driving belt 5010 will drive the two pulleys 501 to rotate synchronously, thereby realizing simultaneous operation of the two threaded rods 401, thereby driving the slider 402 to move. When the slider 402 moves in the track groove 1011, it will drive the fixed seat 4020 and the rotating shaft 4021 to move together, thereby realizing precise control of the inclination angles of the first sieve plate 201, the second sieve plate 202 and the third sieve plate 203.
[0033] Secondly, a first vibration motor 205 and a second vibration motor 206 are installed below and below the opposite side walls of the processing box 200 respectively. The vibration force generated by the second vibration motor 206 is mainly used to control the movement trajectory of the material on the screen surface, so that it tilts downward, so that the material continuously rolls and flips on the screen; the vibration force generated by the first vibration motor 205 is mainly used to generate vertical vibration, so that the material forms a strong impact and vibration on the screen, so that the material is better separated in the screen holes. Through the common reverse rotation and vibration of the first vibration motor 205 and the second vibration motor 206, the screen body produces reciprocating motion, and the material on the screen body continuously jumps and moves due to the force of vibration, and the screening process is completed on the screen holes.
[0034] In addition, the apertures of the first sieve plate 201, the second sieve plate 202 and the third sieve plate 203 decrease in sequence. The material is preliminarily screened by the first sieve plate 201 to separate the material with the largest particle size from the smaller material. The material with the largest particle size screened by the first sieve plate 201 will be discharged through the first discharge port 301. The second sieve plate 202 further screens the material screened by the first sieve plate 201 to separate the material with medium particle size from the smaller material. The material with medium particle size screened by the second sieve plate 202 will be discharged through the second discharge port 302. The third sieve plate 203 performs a final screening on the material screened by the second sieve plate 202 to separate the material with the smallest particle size from the fine powder or impurities. The material with the smallest particle size screened by the third sieve plate 203 will be discharged through the third discharge port 303.
[0035] When the multi-layer screening dual-power vibrating screen structure of the present invention is used, the user puts the material into the processing box 200, starts the first vibration motor 205 and the second vibration motor 206 to make the device vibrate to screen the material, and the largest particle size material after screening by the first sieve plate 201 will be discharged through the first discharge port 301, the second sieve plate 202 further screens the material screened by the first sieve plate 201, and separates the medium-sized particle size material from the smaller particle size, and the medium-sized particle size material after screening by the second sieve plate 202 will be discharged through the second discharge port 302, the third sieve plate 203 performs the final screening on the material after screening by the second sieve plate 202, and separates the smallest particle size material from the fine powder or impurities, and the smallest particle size material after screening by the third sieve plate 203 will be discharged through the third discharge port 303, and the fourth discharge port 204 is used to collect all materials that fail to pass through any layer of the screen plate after screening; when it is necessary to adjust the inclination angle of the first screen plate 201, the second screen plate 202 and the third screen plate 203 according to actual conditions, it is only necessary to rotate the handle 502 to rotate one of the threaded rods 401, and the driving belt 5010 will drive the two pulleys 501 to rotate synchronously, thereby realizing the synchronous rotation of the two threaded rods 401, thereby driving the slider 402 to move along the threaded rod 401, thereby driving the fixed seat 4020 and the rotary shaft 4021 to move together. The design of the fixed seat 4020 enables the rotary shaft 4021 to rotate together between the two inner walls. When the rotary shaft 4021 rotates, it will drive the limit block 4022 to rotate together, thereby changing the corresponding inclination angles of the first screen plate 201, the second screen plate 202 and the third screen plate 203.
