Technical Field

[0001] This utility model relates to the field of waste screening and treatment technology, specifically to a spiral screen mobile station. Background Technology

[0002] The spiral screen comprises an array of multiple spiral shafts with spiral blades. As the spiral shafts rotate, lighter materials are gradually conveyed outwards along the direction of the array, while heavier materials are conveyed axially along the spiral shafts by the action of the spiral blades. Smaller materials fall through the gaps between adjacent spiral shafts. This screening structure can be used in production lines for sorting aged waste and municipal solid waste, as well as for the initial sorting of construction waste.

[0003] Currently, spiral screens are mostly assembled and used as independent screening units. In actual waste treatment production lines, auxiliary equipment such as feeding machines, discharge conveyors, and undersize collection systems are required. This decentralized layout has the following problems: each piece of equipment requires separate infrastructure construction and commissioning, resulting in long initial construction periods and high costs. Once installed, the entire production line is difficult to relocate or rearrange quickly, failing to meet the flexible operational needs of multi-site operation and short-term projects.

[0022] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0023] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0024] An embodiment of a spiral screen mobile station provided by this utility model: like Figures 1 to 9 As shown, The system includes a spiral screen 1, which is detachably fixed to a mobile frame assembly 2. The mobile frame assembly 2 is equipped with height-adjustable support legs. Side support plates 21 are provided on both sides of the upper end of the mobile frame assembly 2. A support plate 22 is provided on the outer top of the side support plate 21. The support legs of the spiral screen 1 are fixed to the support plate 22 by bolts.

[0025] Specifically, the height-adjustable outrigger includes a support cylinder and a support leg fitted inside the support cylinder. Both the support leg and the support cylinder have multiple sets of pin holes arranged vertically, and each pin hole contains a positioning pin.

[0026] The wheel assembly on the mobile frame assembly 2 corresponds to the area below the spiral screen 1. When movement is required, the mobile frame assembly 2 is moved away from the wheel assembly by a power unit. During movement, the outriggers need to be shortened to avoid interference with the bottom surface. This facilitates movement and rapid deployment between different work locations, improving the equipment's versatility and scope of application. Furthermore, different outriggers can be adjusted to varying heights to adapt to different terrains and site conditions.

[0027] In this embodiment, one end of the spiral screen 1 is provided with a feeding conveyor 3 that can be detachably fixed to the mobile frame assembly 2.

[0028] Specifically, the feeding conveyor 3 is placed at an angle from low to high along its conveying direction. An upper connecting plate 31 is provided below the top of the feeding conveyor 3. The upper connecting plate 31 is fixed to the side wall of the spiral screen 1 by bolts. A lower connecting plate 32 is provided below the bottom of the feeding conveyor 3. The lower connecting plate 32 is connected to the side support plate 21 by bolts.

[0029] Specifically, the upper part of the feeding conveyor 3 rests against the shell of the spiral screen 1 and is positioned and supported by the upper connecting plate 31, while the lower part of the feeding conveyor 3 rests against the mobile frame assembly 2 and is positioned and supported by the lower connecting plate 32.

[0030] Bolted connections facilitate the installation, disassembly, and transportation of the equipment. They also allow for quick operation when maintenance, component replacement, or layout adjustments are needed, minimizing downtime and reducing maintenance costs.

[0031] In this embodiment, a feeder 4 is provided at the end of the feeding conveyor 3 away from the spiral screen 1. Specifically, the feeder 4 includes a chain conveyor 41, on which a hopper 42 is provided, and the chain conveyor 41 is fixed on the support plate 22 of the mobile frame assembly 2.

[0032] The end of the hopper 42 that is close to the feeding conveyor 3 is provided with baffles 421 distributed on both sides of the feeding conveyor 3.

[0033] Bolted connections facilitate the installation, disassembly, and transportation of the equipment. They also allow for quick operation when maintenance, component replacement, or layout adjustments are needed, minimizing downtime and reducing maintenance costs.

[0034] It should be noted that the bottom of the chain conveyor 41 is equipped with a support frame. After the chain conveyor 41 is fixed on the support plate 22, there is a sufficient gap between the support frame and the ground.

[0035] In this embodiment, a lightweight material conveyor 5 is provided at the other end of the spiral screen 1. The lightweight material conveyor 5 is supported by outriggers and is not shown in the figure.

[0036] In this embodiment, an adjustable heavy material conveyor 6 is provided on the side of the spiral screen 1. The heavy material conveyor 6 includes a straight conveying section 61 and an inclined conveying section 62. The angle between the straight conveying section 61 and the inclined conveying section 62 is adjustable. The straight conveying section 61 corresponds to the side of the spiral screen 1. An adjusting support frame 621 is provided on the frame of the inclined conveying section 62 to facilitate the adjustment of the angle of the inclined conveying section 62.

[0037] The straight conveyor section 61 is positioned at a higher level and corresponds to the side of the spiral screen 1. This layout prevents heavy materials separated from the spiral screen 1 from directly and violently impacting the straight conveyor section 61 due to excessive height differences as they fall. This avoids equipment damage caused by high-speed impacts of heavy materials on the conveyor.

[0038] Heavy materials first fall onto the higher, straight conveying section 61, and then are conveyed downwards and collected via the inclined conveying section 62. This method of conveying materials horizontally first and then inclined conforms to the mechanical principles of material conveying, enabling heavy materials to be conveyed more smoothly and steadily.

[0039] The straight conveying section 61 and the inclined conveying section 62 are hinged together. The straight conveying section 61 is provided with a connecting ear 611 that connects to the side wall of the spiral screen 1.

[0041] The straight conveying section 61 includes a length adjustment structure for adaptive adjustment. The length adjustment structure includes a first adjustment section 612 and a second adjustment section 613. The upper and lower ends of the first adjustment section 612 and the second adjustment section 613 are provided with auxiliary plates 63, and the auxiliary plates 63 are provided with waist holes.

[0042] The overall length formed by the first adjustment segment 612 and the second adjustment segment 613 is adaptively adjusted by the intermediate connection of the auxiliary plate 63.

[0043] The adjustable support frame 621 includes an adjustable plate 6211 and an adjustable support leg 6212. Both the adjustable plate 6211 and the adjustable support leg 6212 are provided with elongated adjustable grooves 6213, and the two sets of elongated adjustable grooves 6213 are connected by bolts.

[0044] The tilt angle of the inclined conveyor section 62 is adjusted by adjusting the height of the adjusting plate 6211 fixed on the adjusting support leg 6212.

[0045] The mobile frame assembly 2 is detachably fixed with an under-screen conveyor 7 located below the spiral screen 1. The spiral screen 1 is provided with a discharge hopper 11 corresponding to the under-screen conveyor 7 below it. The under-screen conveyor 7 is fixed to the support leg of the spiral screen 1 through a connecting frame 71.

[0046] The material that has passed through the spiral screen 1 is conveyed outward by the under-screen conveyor 7.
