Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically a modular vibrating screening station. Background Technology

[0002] The main function of a screening station is to classify materials to ensure that their quality and specifications meet the requirements. The working principle is to screen materials through a vibrating screen. The materials are fed into the screening equipment by a feeder. The screen generates high-frequency vibration under the action of a high-speed rotating vibrating motor, causing the materials to jump forward on the screen surface. Materials smaller than the screen hole size fall through the screen and become finished products, while materials larger than the screen hole size are discharged from the edge of the screen, thus achieving classification.

[0003] Currently, most crushing and screening stations are fixed. Due to their large size, site transportation is cumbersome, which places higher demands on site and investment costs. Therefore, it is necessary to design a modular vibrating screening station. Utility Model Content

Detailed Implementation

[0020] 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.

[0021] Please see Figures 1-4 This utility model discloses a modular vibrating screening station, including a modular base 1. One end of the modular base 1 is connected to a bracket 2 via a pin. One end of the bracket 2 is hinged to a hydraulic cylinder 3 via a pin, and the other end of the hydraulic cylinder 3 is hinged to the modular base 1 via a pin. A discharge main belt 4 is installed at the bottom of the bracket 2. Rubber shock absorbers 5 are installed around the top of the bracket 2, and a detachable screening machine 6 is bolted to the rubber shock absorbers 5. A vibrating motor 7 is installed at the lower part of the machine slot of the detachable screening machine 6. The trough is equipped with grid-type screen bars 8, which are laid in three layers: upper, middle and lower. With the cooperation of modular base 1 and detachable screening machine 6, the material can be screened on-site in the first line. The material can be discharged without the need to add additional screening equipment, eliminating the intermediate links of transporting the material away from the site for crushing, screening and processing, which greatly reduces the transportation cost of the material. The screening station is flexible in configuration and occupies little space. After the material is processed, the side conveyor belt can be folded and the vibrating screen can be laid flat. The screening station can avoid long-distance transportation of raw materials and the relocation cost is much lower than that of traditional fixed screening stations.

[0022] The detachable screening machine 6 has a diversion discharge hopper 9 at one end of its trough. A connecting platform 10 is installed on the modular base 1, and a foldable side conveyor belt 11 is hinged to the end of the connecting platform 10 by a pin. A telescopic rod 12 is hinged to the rubber shock absorber 5 by a pin, and a hydraulic rod 13 is hinged to the bottom end of the telescopic rod 12 by a pin. The output end of the hydraulic rod 13 is hinged to the top end of the telescopic rod 12 by a pin. A feeding main belt 14 is installed at the top end of the telescopic rod 12, and the other end of the feeding main belt 14 is hinged to the modular base 1 by a pin. A feed hopper 15 is installed on the feeding main belt 14.

[0023] Specifically, the bracket 2 is a rectangular frame structure, and the conveying surface of the discharge main belt 4 is located directly below the trough of the detachable screening machine 6.

[0024] In this implementation plan, the core function of bracket 2 is to provide support, fixation and protection for equipment or structure, ensuring its stability and functionality. The main discharge belt 4 is a V-belt conveyor. In order to make the structure easier to see intuitively, the conveyor belt of the V-belt conveyor is hidden in the figure.

[0025] Specifically, the hydraulic cylinder 3 is located on both sides of the bracket 2, and the output end of the hydraulic cylinder 3 is hinged to the bracket 2.

[0026] In this embodiment, the hydraulic cylinder 3 is used to adjust the tilt angle of the detachable screening machine 6, thereby helping to achieve more efficient operation. An appropriate tilt angle can improve the separation efficiency of materials. Due to the presence of the tilt angle, the materials flow downward more easily on the screen surface, allowing fine particles to pass through the screen more quickly, thereby improving the grading effect of the materials. At the same time, the tilt angle also helps to prevent materials from clogging the screen, further improving the continuity and stability of screening. Within a certain range, increasing the tilt angle of the screen surface can increase the production capacity of the equipment. This is because the increase in the tilt angle makes the material move faster on the screen surface and shortens the residence time of the material on the screen surface, thereby improving the processing capacity of the equipment.

[0027] Specifically, the diversion discharge hopper 9 has three layers, and the positions of the grid screen bars 8 in each layer correspond to the positions of the layers.

[0028] In this implementation scheme, after each layer of grid screen bar 8 separates large and small particles of material, the material flows out from the diversion discharge hopper 9.

[0029] Specifically, there are three connecting platforms 10, corresponding to the positions of the diversion discharge hoppers 9 on each layer.

[0030] In this implementation scheme, the connecting platform 10, as the name suggests, is an integrated platform used to connect different devices or systems, and is used to transfer the outflowing material to the foldable side conveyor belt 11 for conveying.

[0031] Specifically, the main feeding belt 14 is mounted above the trough of the detachable screening machine 6, and the feed hopper 15 is located at the end of the main feeding belt 14.

[0032] In this implementation plan, the feeding main belt 14 and the discharging main belt 4 are both V-type belt conveyors. For the sake of visually demonstrating the structure, the conveyor belt of the V-type belt conveyor is hidden in the figure.

[0033] During operation, the material enters the feed hopper 15 and then flows through the main feeding belt 14 into the upper screen of the detachable screening machine 6. The screening machine is vibrated by a vibrating motor 7 (one side-plate vibrating motor is installed on each side of the screening machine, and the side-plate vibrating motor is directly bolted to the side plate of the screening machine through the flange in the middle of the motor. The installation position must be close to the center of gravity of the vibrating equipment and the position is adjusted according to the number of screening layers. Multi-layer screens are usually installed in the middle layer position. Compared with the traditional eccentric block vibrating motor, the side-plate motor eliminates the transmission mechanism and on-site assembly process, and can be pre-assembled before leaving the factory, reducing the assembly complexity. The excitation force adjustment supports stepless adjustment from 0 to 100% to meet different working conditions). The material is screened by the grid screen bars 8 of the first, second and third layers. The smallest material falls onto the discharge main belt 4 and is conveyed to the ground stockpile by the discharge main belt 4. The material on the first, second and third layers is discharged through the diversion discharge hopper 9. The material is piled up by three foldable side conveyor belts 11 in three directions. With the cooperation of modular base 1 and detachable screening machine 6, the material can be screened on-site. The material can be discharged without the need for additional screening equipment, eliminating the intermediate links of transporting the material away from the site for crushing, screening and processing, which greatly reduces the transportation cost of the material. The screening station is flexible in configuration and occupies little space. After the material is processed, the side conveyor belts can be folded and the vibrating screen can be laid flat. The screening station can avoid long-distance transportation of raw materials and the relocation cost is much lower than that of traditional fixed screening stations. The detachable screening machine 6 and modular base 1 are connected by rubber shock absorbers 5. When it is necessary to disassemble, simply remove the bolts of the rubber shock absorbers 5 and then pull out the pins connecting the main feeding belt 14 to lift it open. It is convenient and quick. The screening station is suitable for sand and gravel aggregate screening, mineral processing and construction waste treatment, and is especially suitable for operation scenarios with limited space or frequent relocation.

[0034] In summary, this modular vibrating screening station, through the cooperation of the modular base 1 and the detachable screening machine 6, can perform on-site screening of materials without the need for additional screening equipment. This eliminates the intermediate steps of transporting materials away from the site for crushing, screening, and processing, greatly reducing material transportation costs. The screening station is flexible in configuration, occupies little space, and after material processing, the side conveyor belt can be folded and the vibrating screening machine can be laid flat. This screening station avoids long-distance transportation of raw materials, and the relocation cost is far lower than that of traditional fixed screening stations.
