[0002] Coal gasification slag is the solid waste generated during the coal gasification process. Since coal is the main energy source in my country and coal gasification process is one of the important technologies of the coal industry, my country discharges a large amount of coal gasification slag every year. At present, the country has put forward the requirement of building a "sponge city". Some researchers have proposed to use geopolymers instead of cement in traditional permeable concrete as a cementitious material, and to improve the mechanical properties of permeable concrete by taking advantage of its advantages such as fast early strength formation, high compressive strength, high temperature resistance, and chemical corrosion resistance, so as to adapt the mechanical properties to the permeable properties and obtain permeable concrete with excellent mechanical properties and permeable properties.
[0003] It can be seen that the application of gasified slag in concrete as a building material is the general trend and one of the main development directions and research directions of future construction. The particle size of gasified slag is one of the main factors restricting the performance of concrete, so the gasified slag must be screened out during use. In the prior art, the gasified slag is directly fed through a belt conveyor during screening, and the feeding process is slow and affects the production efficiency. In addition, when the screening device is shut down for inspection, the rest of the equipment needs to be shut down together to avoid suffocation, which will further affect the overall screening efficiency of the gasified slag.

[0021] Specifically, please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of the screening device for gasified slag provided in an embodiment of the present application in a first state, Figure 2 This is a schematic diagram of the overall structure of the screening device for gasified slag provided in an embodiment of the present application in the second state, Figure 3A schematic diagram of a partial cross-sectional structure of a rotating roller assembly provided in an embodiment of the present application. The screening device 100 applied to gasified slag includes a screening box 110 and a feeding component 120, and the screening box 110 is used to screen the gasified slag and discharge the materials separately. The screening box 110 is a prior art and has been fully disclosed, and will not be described in detail here. The top of the screening box 110 is open to form an inlet end 111, and the gasified slag coarse aggregate is put into the inner cavity of the screening box 110 through the inlet end 111 formed at the top of the screening box 110. The feeding component 120 includes a support beam 121 arranged on the top of the screening box 110, and the support beam 121 here can be the bottom plate of a two-story factory building. A movable hole 121a is provided in the middle of the support beam 121, and a buffer box 122 is movably provided in the movable hole 121a. The buffer box 122 is located above the inlet end 111 of the screening box 110. The buffer box 122 can move up and down in the movable hole 121a driven by components such as gears 123. When the screening box 110 needs to be filled, the buffer box 122 moves down, otherwise the buffer box 122 moves up and resets. A plurality of racks 122a are vertically arranged around the screening box 110, and a gear 123 is meshed at the rack 122a. The gear 123 is rotatably arranged on the support beam 121. The gear 123 is connected to a driving component (not shown in the figure). Driven by the driving component, the gear 123 rotates, and then the gear 123 drives the rack 122a and the buffer box 122 to move upward. When the driving component is reversed, the buffer box 122 falls. It should be noted that in order to ensure that the buffer box 122 can maintain a certain stability during the upward or downward movement, it can be arranged by conventional means such as a limit slide rail. At least one belt conveyor 124 is arranged on the support beam 121, and the output end of the belt conveyor 124 extends to the upper opening of the buffer box 122. The belt conveyor 124 is used to transport the unscreened gasified slag coarse aggregate to the top of the buffer box 122. The bottom of the buffer box 122 is provided with an electromagnetic gate valve 122b. When the electromagnetic gate valve 122b is opened, the gasified slag in the buffer box 122 can fall into the screening box 110. A rotating rod component 125 is provided inside the buffer box 122 above the electromagnetic gate valve 122b. The rotating rod component 125 drives the gasified slag to fall during its rotation. On the one hand, it prevents the gasified slag from being discharged too quickly and damaging the screen plate in the screening box 110. On the other hand, it can control the gasified slag to be discharged evenly.
[0022] As can be seen from the above, in the embodiment of the present application, the screening box 110 is loaded by setting a loading component 120, and the loading component 120 includes a buffer box 122, and the buffer box 122 has a large capacity, and then when the screening box 110 is shut down for inspection or maintenance, the belt conveyor 124 can continue to transport the gasified slag to the buffer box 122 for temporary storage, thereby playing a buffering role, so as not to shut down the entire production line when the screening box 110 is shut down. On the other hand, in the embodiment of the present application, a rack 122a is provided on the outside of the buffer box 122, and the rack 122a, in cooperation with the gear 123, can drive the buffer box 122 to move up or down, and then when it is necessary to add material to the screening box 110, the buffer box 122 falls, reducing the falling height of the gasified slag, and further preventing the screening box 110 from being damaged. The present application also controls the gasified slag to be evenly discharged by setting a rotating roller component 125.
[0023] In some embodiments, the rotating stick component 125 includes two symmetrically arranged rotating stick bodies 125a, with a gap between the two rotating stick bodies 125a, and the two ends of the rotating stick bodies 125a are rotatably connected to the inner wall of the buffer box 122, and one end of the rotating stick body 125a penetrates the outside of the buffer box 122 and is coaxially connected to the rotating motor 125b. In the embodiment of the present application, a specific setting method of the rotating stick component 125 is shown. During the working process, the rotating stick body 125a can be driven to rotate by the rotating motor 125b, thereby realizing auxiliary unloading, and the unloading speed can be controlled to a certain extent by the rotation speed of the rotating stick body 125a.
[0024] In some embodiments, there are multiple belt conveyors 124, and the multiple belt conveyors 124 are arranged in a circular array on the support beam 121 with the central axis of the buffer box 122 as the center. In the embodiment of the present application, the support beam 121 can be the bottom plate of the two-story factory building to facilitate the installation of the belt conveyor 124. The multiple belt conveyors 124 can transport the gasified slag from different stacking points to the buffer box 122, thereby accelerating the speed of the belt conveyor 124 loading the buffer box 122.
[0025] In some embodiments, a dust suppression cover 126 is included, and the outer cover of the dust suppression cover 126 is connected to the bottom of the buffer box 122. The bottom of the dust suppression cover 126 is opened and expanded outward, and then the cover is arranged above the inlet end 111. In the embodiment of the present application, the dust suppression cover 126 is provided to prevent the generation of dust rising and affecting the gear 123 and other components, and the dust suppression cover 126 moves up and down together with the buffer box 122.
[0026] In some embodiments, a dust removal assembly 127 is included, and the dust removal assembly 127 includes a negative pressure pump 127a and a dust collecting box 127b. The input end of the negative pressure pump 127a is connected to the inner cavity of the dust suppression cover 126 through a hose 127c, and the output end of the negative pressure pump 127a is connected to the dust collecting box 127b through a filter bag 127d. In the embodiment of the present application, through the above-mentioned configuration, during the working process, after the negative pressure pump 127a is started, the dust inside the dust suppression cover 126 can be sucked into the dust collecting box 127b through the hose 127c, and the dust and air are separated through the filter bag 127d.
[0027] In some embodiments, a protective shell 123a is provided on the outer side of the gear 123. In the embodiment of the present application, the protective shell 123a is provided to prevent the gear 123 from being damaged by collision.
[0028] In some embodiments, the upper opening of the buffer box 122 expands outward to form a funnel-shaped opening. In the embodiment of the present application, through the above arrangement, the top opening of the buffer box 122 is opened to increase the area of its positive projection, thereby effectively preventing leakage of materials when the belt conveyor 124 feeds materials to the buffer box 122.
