Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of the feeding system of power plant, especially relates to a stock bin activator. BACKGROUND

[0002] In various industrial scenes such as biomass power plants, solid waste power plants and coal power plants involving material conveying, the stock bin as a key component of the feeding system is directly related to the working efficiency of the whole feeding system. The material stored in the stock bin is prone to arching due to the combined action of the pressure generated by its own gravity and the adhesion and cohesion between the material particles. This phenomenon can cause the material to block in the stock bin, seriously affecting the normal production process.

[0003] At present, the conventional stock bin design has obvious limitations. On the one hand, if the stock bin volume is designed too large, the spiral blades in the common screw feeder are prone to congestion when the stock bin is discharging. This congestion not only makes the material discharge difficult, but also greatly reduces the whole feeding efficiency, thereby affecting the subsequent production process. On the other hand, to avoid the congestion problem of large stock bins, small stock bin design can alleviate the congestion of spiral blades to some extent, but it brings new troubles. Small stock bins need to be frequently fed by workers due to their small volume, which undoubtedly greatly increases the labor burden, and the frequent feeding process may also affect the continuity and stability of feeding.

[0004] In summary, the existing stock bin design has many shortcomings in dealing with material arching, discharging congestion and labor burden, and there is an urgent need for an innovative device that can effectively prevent material aggregation and block the discharge port, is suitable for large stock bin design, can ensure smooth discharging and reduce the feeding frequency of workers.

[0016] The silo activator has the following beneficial effects:

[0017] 1. Effectively prevent material arching and clogging: the number of paddles of the first and second paddling rollers is different (for example, 5 and 6), so that during rotation, their grooves will not align at the same time. This design avoids the accumulation of materials when the grooves are aligned, thereby preventing material congestion. The design of the number difference of 1 is sufficient to break the symmetry between the paddling mechanisms, ensuring that the relative position of the grooves changes constantly during rotation, further reducing the risk of material congestion.

[0018] 2. Suitable for large bin design: the design of the bin activator makes it possible to use large-capacity bins, reducing the frequency of workers adding materials, reducing the burden of manual labor, and ensuring the continuity and stability of production.

[0019] 3. Uniform mixing: the equal interval arrangement of the paddles ensures uniform mixing, improves the flowability of the material, and avoids local accumulation.

[0020] 4. Enhance the stability of the bin structure: the two side surfaces of the bin are designed as inclined surfaces, which not only increase the volume of the bin, but also make the material more easily slide to the bottom of the hopper under the action of gravity, while decomposing the pressure of the material on the side wall, enhancing the structural stability of the bin.

[0021] 5. Easy to maintain and clean: the bin wall is provided with an access door, which facilitates the cleaning and maintenance of the interior of the bin, improving the operability and maintenance convenience of the equipment.

[0022] In summary, the bin activator of the present application has significant advantages in solving material arching, material congestion, reducing manual burden, and improving production efficiency, and is suitable for various industrial scenes involving material conveying.

[0029] The two ends of the first material stirring rollers 31 and the second material stirring rollers 32 are arranged to pass through the activation silo 2 and are supported by the bearing seat 5. The speed reducer 4 is in one-to-one correspondence with the number of the material stirring rollers of the material stirring mechanism 3 and is connected to the material stirring rollers in correspondence through the shaft couplings 6 to drive the material stirring rollers to rotate. The speed reducer 4 is fixed on the support table 8 through the motor base 41. The activation silo 2 is provided with shaft seat bosses 21 on the two sides, and the bearing seat 5 is fixed on the shaft seat bosses 21.

[0030] In the embodiment, two first material stirring rollers 31 and two second material stirring rollers 32 are arranged, and the adjacent first material stirring rollers 31 and the adjacent second material stirring rollers 32 are arranged at equal distances, and the minimum distance between the material stirring plates of the adjacent first material stirring rollers 31 and the material stirring plates of the adjacent second material stirring rollers 32 is 60 mm.
