Description

Technical Field

[0001] The present invention relates to the technical field of dust removal and environmental protection, and particularly to a rotary drum separate storage ash bin. Background Art

[0002] In the production and processing industry, a large amount of fly ash impurities with a large number of filaments are often generated. Due to the accumulated ash having different particle sizes, being light, fluffy, and having strong water absorption, it is easy to agglomerate into a cake shape in a short time under humid environments or continuous impacts during ash storage, and basically loses its fluidity, making it unsuitable for the overall storage treatment method. Therefore, the treatment of such accumulated ash is a major problem in the processing industry.

[0003] Currently, the commonly used accumulated ash storage bins are all steel fixed temporary storage bins. If a fixed temporary storage bin is forcibly used to handle such accumulated ash, it will cause many inconveniences during the collection and transportation process, and the existing drawbacks are as follows: (1) The existing ash bin has a structural form of a traditional cylinder (round or square, etc.) plus a cone, and the volume of the bin body is usually large. The cone design at the bottom of the bin body makes it easy to generate throttling during ash unloading, and has extremely high requirements for the fluidity of the ash; (2) The ash discharge valve is usually installed at the bottom of the bin cone. Although the slope of the cone is greater than the flowing angle of the accumulated ash, due to the easy agglomeration characteristics of the ash itself, it does not have the condition of natural flow after agglomeration, resulting in the blockage of the ash discharge port and the inability to discharge ash; (3) Once the ash discharge port of the existing ash bin is blocked, manual ash discharge is required, which not only has a large workload for personnel but also generates a large amount of dust, which is extremely unfavorable to the health of personnel and the factory environment; (4) The bin content is prone to ash accumulation, and manual cleaning of the accumulated ash is required after ash discharge, resulting in waste of labor. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a rotary drum separate storage ash bin that is easy to discharge ash, does not get blocked, does not store ash, has little dust during ash discharge, and is convenient for the external transportation of accumulated ash.

[0005] To solve the above problems, a rotary drum storage ash bunker according to the present invention is characterized in that: the ash bunker includes a bunker chassis and an ash bunker support connected together, and a rotary bunker in the shape of a cylinder placed on the bunker chassis; a square seat placed on the ash bunker support is provided at the bottom of the bunker chassis, and a central rotating shaft is installed in the square seat; a pressure-bearing bearing is installed on the central rotating shaft; an ash inlet is provided at the center of the top of the rotary bunker, and a ash distributing cap is provided below the ash inlet; a central sleeve is provided below the ash distributing cap, and several partition plates are evenly distributed on the central sleeve, and the space between the central sleeve and the rotary bunker is evenly divided into several small bins by the several partition plates; a driven gear ring is provided on the outer side of the rotary bunker where the ash distributing cap is located, and the driven gear ring meshes with a driving gear; a hollow rotating shaft is provided in the central sleeve, and the hollow rotating shaft is connected to the central rotating shaft; three bunker positioning devices forming a three-jaw chuck type positioning structure are evenly distributed on the middle floor of the ash bunker support; a maintenance opening and an ash discharge opening are left on the bottom floor of the bunker chassis; a flap valve is installed at the lower end of the ash discharge opening, and a screw conveyor is provided below the flap valve; a telescopic chute is connected to the outlet of the screw conveyor.

[0006] The surface of the bunker chassis is spirally descending.

[0007] The ash discharge openings correspond to the small bins one by one, and the cross-sectional size of the small bins is slightly smaller than the size of the ash discharge openings.

[0008] A maintenance opening is left at the center of the bottom floor of the bunker chassis.

[0009] The present invention has the following advantages compared with the prior art:

[0010] 1. In the present invention, the rotary bunker is divided into several small bins, and the cross-sectional size of the small bins is slightly smaller than the size of the ash discharge openings; when discharging ash, the ash discharge openings correspond to each small bin in turn, forming a direct ash discharge channel. Even if the ash in the small bins is caked, the ash discharge can be smooth, without bridging, blocking, or ash accumulation.

[0011] 2. In the present invention, the surface of the bunker chassis is spirally descending, and the rotary bunker rotates at a constant speed when discharging ash, reducing the rotary ash discharge resistance and lowering the energy consumption of the speed reducer.

[0012] 3. The present invention has a fully enclosed structure, minimizing dust leakage during the ash storage and discharge processes as much as possible.

[0013] 4. In the present invention, an ash distributing cap is provided below the ash inlet, which can evenly disperse the ash entering the ash bunker into the rotary bunker.

[0014] 5. In the present invention, a maintenance opening is left at the center of the bottom floor of the bunker chassis, facilitating the maintenance of the equipment.

[0015] 6. An airslide valve is installed at the lower end of the ash discharge port of the present invention, and a screw conveyor is provided below the airslide valve; a telescopic chute is connected to the outlet of the screw conveyor to facilitate the external transportation of accumulated ash.
