Description

Technical Field

[0001] The utility model belongs to the technical field related to screening, and particularly relates to a vibrating distributor for a dual-frequency vibrating screen. Background Art

[0002] Screening machine refers to a machine that uses the principle of vibration motor excitation to make the material be thrown up on the screen surface, and at the same time move forward in a straight line to achieve the purpose of screening with a reasonably matched screen. The dual-frequency vibrating screen works on the principle of combined vibration frequency, which are low and high frequencies respectively; the vibration force of different frequencies weakens the bite friction and sliding friction between particles, and the movement of different particles shows great differences, so that the particles on the screen are more fully loosened, and the material penetration rate is increased, ultimately achieving the purpose of improving screening efficiency and productivity. Vibrating screens are widely used in the industry for material screening, mainly to screen materials into different particle sizes to obtain materials of the required particle size. Before screening, the vibrating screen needs to be used with a distributor to evenly distribute the material to make the subsequent screening more uniform, but the relevant distributor has the following disadvantages in actual use:

[0003] Conventional distributors only distribute the material evenly on the screen of the vibrating screen, mostly relying on the natural fall of the material due to gravity. However, once the feed amount is too large, uneven distribution will occur, and the distributor may also be blocked, so the distribution method needs to be improved;

[0004] Secondly, screens, grilles and other components are usually set in the distributor to evenly distribute the incoming materials, so as to achieve uniform distribution. However, the screen structure needs to be replaced after long-term use and is easy to be damaged. In addition, the distributor is in direct contact with the unscreened materials, so it is subject to great impact and higher degree of wear. Therefore, a distribution structure that is easy to disassemble and assemble is required. Conventional screen distribution structures mostly require a large number of fasteners for installation, which is very time-consuming and labor-intensive.

[0005] Finally, most distributors are open structures. If they are used for relatively dry and powdery materials, it is easy to generate dust, causing pollution to the surrounding environment, loss of materials, and increased costs. Utility Model Content

[0006] The utility model aims to provide a vibrating distributor for a dual-frequency vibrating screen, which solves the problems that the distribution method of conventional distributors is still not perfect, the screen distribution structure in the distributor is inconvenient to disassemble and assemble, and the open structure of the distributor when in use easily causes dust to fly, pollutes the environment, and increases material costs by arranging a distribution shell, a distribution screen frame, a distribution screen, a vibration motor, a center plate, a dispersion arc plate, a mounting groove, and a dust cover.

The cloth screen frame is tilted along the mounting grooves as a whole, and the lower end of the cloth screen frame is inserted into the end groove adjacent to it.

[0013] Furthermore, the bottom surface of the dispersion arc plate is flush with the upper end surface of the cloth shell, and the length of the dispersion arc plate is equal to the inner cavity width of the cloth shell, and the length of the dispersion arc plate is smaller than the length of the center plate.

[0014] Furthermore, screw holes 2 are provided in the two end walls of the center plate, screw holes 1 penetrating the side wall of the cloth shell are provided in the vertical groove, and fastening bolts are screwed into the screw holes 1 and 2 in sequence from the outside of the cloth shell.

[0015] The utility model has the following beneficial effects:

[0031] The cloth shell 1 is the main cloth structure, which is installed on the higher feeding port of the linear vibrating screen. The cloth shell 1 and the vibrating screen should be criss-crossed in a top view. A dust cover plate 3 is installed on the cloth shell 1 to prevent dust from escaping when conveying materials and cloth. The cloth shell 1 uses a cloth screen frame 4 and a cloth screen 401 inside it for uniform cloth distribution. The cloth screen frame 4 is inserted obliquely along the installation groove 103. The two cloth screen frames 4 are symmetrically distributed, with the higher end close to the center of the cloth shell 1. The center plate 5 is then inserted into the vertical groove 104 to complete the preliminary installation. The dispersion arc plate 501 at the upper end of the center plate 5 is used to disperse materials onto the two cloth screens 401.

[0032] A feed pipe 302 is fixed through the center of the top of the dust cover 3, and a flange is provided on the upper end of the feed pipe 302. A frame strip 301 is fixed at the outer edge of the bottom of the dust cover 3. The feed pipe 302 is connected to an external feeding device to transport the material to be screened into the cloth shell 1.

[0033] A frame strip 101 is fixed at the top outer edge of the cloth shell 1, and the frame strip 101 and the frame strip 2 301 are fixedly connected by bolts and nuts; the bottom end of the cloth shell 1 is an open structure;

[0034] The outer part of the cloth shell 1 is connected to the dust cover plate 3 through the combination of the frame bar 1 101 and the frame bar 2 301, and the relevant bolts, nuts and other fasteners are used to connect the cloth shell 1. The opening below the cloth shell 1 is directly connected to the inside of the vibrating screen to guide the material for cloth use.

[0035] A connecting column 202 is fixed to the outside of one end of the cloth shell 1, and a mounting block 201 is fixed to the end of the connecting column 202 away from the cloth shell 1, and two vibration motors 2 are respectively fixed on two opposite sides of the mounting block 201;

[0036] Two vibration motors 2 are mounted on a mounting block 201 , and the mounting block 201 is connected to the end wall of the fabric shell 1 via a connecting column 202 , so that the vibration of the vibration motor 2 can be transmitted to the fabric shell 1 .

[0037] End grooves 105 are also provided on the two inner end walls of the material distribution shell 1, and the two ends of the end grooves 105 are respectively connected to the mounting grooves 103 on the two inner side walls of the material distribution shell 1, and the material distribution screen frame 4 is tilted along the mounting grooves 103 as a whole, and the lower end of the material distribution screen frame 4 is inserted into the end groove 105 adjacent thereto;

[0038] The coordinated setting of the end groove 105 enables the cloth screen frame 4 to be inserted into the installation groove 103, and its lower end is inserted into the end groove 105 to achieve three-sided limitation. Then, the center plate 5 is inserted into the vertical groove 104, and the higher end of the cloth screen frame 4 abuts against the side of the center plate 5 to achieve four-sided limitation. In this way, there is no need for a large number of fasteners to install the cloth screen frame 4, and disassembly and assembly are relatively convenient.

[0039] The bottom surface of the dispersion arc plate 501 is flush with the upper end surface of the distribution shell 1 , and the length of the dispersion arc plate 501 is equal to the inner cavity width of the distribution shell 1 , and the length of the dispersion arc plate 501 is less than the length of the center plate 5 .

[0040] The two end walls of the center plate 5 are provided with screw holes 502, and the vertical groove 104 is provided with screw holes 106 penetrating the side wall of the cloth shell 1, and the outside of the cloth shell 1 is screwed with fastening bolts 102 in the screw holes 106 and 502 in sequence;

[0041] After the center plate 5 is inserted into the vertical slot 104, the centers of the screw hole 106 and the screw hole 2 502 are aligned, and the fastening bolt 102 is screwed into the corresponding screw hole 106 and the screw hole 2 502 from the outside of the cloth shell 1 to achieve a fixed connection between the center plate 5 and the cloth shell 1. After the center plate 5 cannot move, the cloth screen frame 4 cannot move either.

[0042] The specific working principle of the utility model is as follows: first, the cloth shell 1 is installed on the higher feeding port of the linear vibration screen, and then the cloth screen frame 4 is obliquely inserted along the installation groove 103, and the two cloth screen frames 4 are symmetrically distributed, and the higher end is close to the center of the cloth shell 1, and then the center plate 5 is inserted into the vertical groove 104 to complete the preliminary installation. After the center plate 5 is inserted into the vertical groove 104, the centers of the screw hole 106 and the screw hole 2 502 are aligned, and the fastening bolts 102 are screwed into the corresponding screw holes 106 and the screw holes 2 502 from the outside of the cloth shell 1 to achieve the fixed connection between the center plate 5 and the cloth shell 1. Finally, the cloth shell 1 is connected to the dust cover plate 3 by combining the frame strip 101 and the frame strip 2 301 outside the cloth shell 1, and the relevant bolts, nuts and other fasteners are connected, so that the cloth shell 1 is connected to the dust cover plate 3, and the material to be screened is transported into the cloth shell 1 through the feed pipe 302;

[0043] During screening, because the dispersion arc plate 501 on the center plate 5 is located directly below the feed pipe 302, the material directly impacts the dispersion arc plate 501 and does not directly impact the cloth screen 401, and then slides down along the cloth screen 401 in the cloth screen frame 4. At the same time, a vibration motor 2 is arranged outside the cloth shell 1. When the vibration motor 2 works, the vibration is transmitted to the cloth shell 1 and then to the cloth screen frame 4, so that the cloth screen 401 vibrates, and the material accumulated on its surface will gradually slide down, completing a uniform cloth process and ensuring continuous cloth operation.

[0044] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
