Description

Technical Field

[0001] The invention relates to the technical field of feeding systems of power plants, and in particular to a silo activator. Background Art

[0002] In various industrial scenarios involving material transportation, such as biomass power plants, solid waste power plants, and coal-fired power plants, the silo is a key component of the feeding system, and its performance is directly related to the working efficiency of the entire feeding system. The materials stored in the silo are prone to arching due to the combined effects of the pressure generated by their own gravity and the adhesion and cohesion between the material particles. This phenomenon can cause the material to be blocked in the silo, seriously affecting the normal production process.

[0003] At present, conventional silo designs have obvious limitations. On the one hand, if the silo volume is designed to be too large, congestion is very likely to occur between the spiral blades in the common spiral feeding device when the silo is unloaded. This congestion not only makes the material unloading difficult, but also greatly reduces the overall feeding efficiency, thereby affecting subsequent production links. On the other hand, in order to avoid the congestion problem of large silos, the use of small silo design can alleviate the congestion of spiral blades to a certain extent, but it brings new troubles. Due to the small volume of small silos, workers need to frequently add materials to them, which undoubtedly greatly increases the labor burden, and during the frequent adding process, the continuity and stability of the feeding may be affected if not handled with care.

[0004] In summary, the existing silo design has many shortcomings in dealing with material arching, material discharge congestion and labor burden. There is an urgent need for an innovative device that can effectively prevent material agglomeration from blocking the discharge port, is suitable for large silo design, and can ensure smooth material discharge without congestion, while reducing the frequency of staff adding materials. Summary of the invention

[0005] The technical purpose of the present invention is to provide a silo activator, which is not only suitable for large silo design and reduces the frequency of material addition by workers, but also can effectively prevent material agglomeration from blocking the discharge port, thereby ensuring smooth discharge.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] The silo activator is characterized in that it comprises: a silo, an activation silo, a material discharging mechanism, a reduction motor, a bearing seat and a support platform; the silo is located above the activation silo and is connected and docked with the activation silo, the activation silo is fixed on the support platform, the top surface of the silo is a material inlet, the bottom surface of the activation silo is a material outlet, and is docked with downstream equipment; the material discharging mechanism is arranged in the activation silo; the material discharging mechanism comprises a first material discharging roller and a second material discharging roller, the first material discharging roller and the second material discharging roller are horizontally parallel and alternately arranged, and both ends thereof pass through the activation silo and are supported by one of the bearing seats respectively; the reduction motor corresponds to the number of material discharging rollers of the material discharging mechanism one by one, and is correspondingly connected thereto through a coupling to drive the material discharging rollers to rotate respectively; a plurality of material discharging plates corresponding to their lengths are provided on the rotating shafts of the first material discharging roller and the second material discharging roller; the number of material discharging plates on the first material discharging roller is N equidistantly arranged along its circumference; the number of material discharging plates on the second material discharging roller is N+1 equidistantly arranged along its circumference.

[0008] According to a further preferred technical solution, adjacent first material-diverting rollers and second material-diverting rollers are arranged at equal distances.

[0009] According to a further preferred technical solution, the spacing between the adjacent first and second material-diverting rollers is set to 60 mm.

[0010] According to a further preferred technical solution, five material-diverting plates are arranged on the rotating shaft of the first material-diverting roller; and six material-diverting plates are arranged on the rotating shaft of the second material-diverting roller.

[0011] According to a further preferred technical solution, two of the first material-moving roller and two of the second material-moving roller are provided.

[0012] According to a further preferred technical solution, an inspection door is provided on the silo wall.

[0013] A further preferred technical solution is that the left and right side surfaces of the silo are inclined surfaces. The setting of the inclined surfaces allows the material to smoothly slide to the bottom of the hopper under the action of gravity, while increasing the volume of the silo under the same footprint, and can effectively decompose the pressure of the material on the side walls, thereby enhancing the stability of the silo structure and facilitating the cleaning and maintenance of the interior of the silo.

[0014] According to a further preferred technical solution, the reduction motor is fixed on the support platform via a motor base.

[0015] According to a further preferred technical solution, shaft seat bosses are provided on both sides of the activation chamber, and the bearing seat is fixed on the shaft seat bosses.

[0016] The beneficial effects of the present invention are:

[0017] 1. Effectively prevent material arching and clogging: The first and second feed rollers have different numbers of feed plates (e.g. 5 and 6), so that their grooves will not be aligned at the same time during rotation. This design avoids the accumulation of materials when the grooves are aligned, thus preventing material congestion. The design with a number difference of 1 is enough to break the symmetry between the feed mechanisms, ensuring that the relative positions of the grooves are constantly changing during rotation, further reducing the risk of material congestion.

[0018] 2. Suitable for large silo design: The design of the silo activator makes it possible to use large-volume silos, reducing the frequency of staff adding materials, reducing the labor burden, and ensuring the continuity and stability of production.

[0019] 3. Uniform stirring: The equally spaced setting of the material diverter plates ensures uniform stirring, improves the fluidity of the material and avoids local accumulation.

[0020] 4. Enhance the structural stability of the silo: The two sides of the silo are designed as inclined surfaces, which not only increases the volume of the silo, but also makes it easier for the material to slide to the bottom of the hopper under the action of gravity, while decomposing the pressure of the material on the side wall and enhancing the structural stability of the silo.

[0021] 5. Easy to maintain and clean: There is an inspection door on the silo wall, which is convenient for cleaning and maintenance inside the silo, improving the operability and maintenance convenience of the equipment.

[0022] In summary, the silo activator of the present invention has significant advantages in solving material arching, material discharge congestion, reducing labor burden and improving production efficiency, and is suitable for various industrial scenarios involving material transportation.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example: Structure and working process of silo activator

[0028] This embodiment provides a silo activator suitable for large-capacity silos in biomass power plants, and the specific structure is as follows: Figure 1 As shown. The silo activator includes: a silo 1, an activation silo 2, a material dispensing mechanism 3, a reduction motor 4, a bearing seat 5 and a support platform 8. The silo 1 is located above the activation silo 2, and is connected and docked with the activation silo 2, and the activation silo 2 is fixed on the support platform 8. The top surface of the silo 1 is a feed port, and the bottom surface of the activation silo 2 is a discharge port, and the discharge port is docked with downstream equipment. The material dispensing mechanism 3 is arranged in the activation silo 2, and includes a first material dispensing roller 31 and a second material dispensing roller 32, which are horizontally parallel and alternately arranged. The rotating shafts of the first material dispensing roller 31 and the second material dispensing roller 32 are provided with a plurality of material dispensing plates 33 corresponding to their lengths.

[0029] Both ends of the first material-dispensing roller 31 and the second material-dispensing roller 32 pass through the activation bin 2 and are supported by the bearing seats 5 respectively. The reduction motor 4 corresponds to the number of the material-dispensing rollers of the material-dispensing mechanism 3 one by one, and is connected thereto through the coupling 6 to drive the material-dispensing rollers to rotate respectively. The reduction motor 4 is fixed to the support platform 8 through the motor base 41. Shaft seat bosses 21 are provided on both sides of the activation bin 2, and the bearing seats 5 are fixed on the shaft seat bosses 21.

[0030] In this embodiment, two first and second feed rollers 31 and 32 are provided, and adjacent first and second feed rollers 31 and 32 are arranged at equal distances, and the minimum spacing between the feed plates of adjacent first and second feed rollers 31 and 32 is 60 mm. Five feed plates 33 are provided on the rotating shaft of the first feed roller 31; and six feed plates 33 are provided on the rotating shaft of the second feed roller 32. The feed plates 33 are arranged at equal intervals along the circumference. In this design, the number of feed plates of the first and second feed rollers 31 and 32 is different (5 and 6), so that their grooves will not be aligned at the same time during the rotation process. This design avoids the concentrated accumulation of materials when the grooves are aligned, thereby preventing material congestion.

[0031] An inspection door 7 is provided on the wall of the silo 1 to facilitate cleaning and maintenance of the interior of the silo 1. In addition, the left and right sides of the silo 1 are inclined surfaces, which allow the material to smoothly slide to the bottom of the hopper under the action of gravity, while increasing the volume of the silo under the same floor space, and can effectively decompose the pressure of the material on the side wall, thereby enhancing the stability of the silo structure.

[0032] In actual use, the working process of the silo activator is as follows:

[0033] 1. Material enters through the entrance of silo 1.

[0034] 2. The material accumulates in silo 1 and slides to the bottom of the hopper under the action of gravity.

[0035] 3. The material-dispensing mechanism 3 starts to work, the first material-dispensing roller 31 and the second material-dispensing roller 32 rotate under the drive of the reduction motor 4, and the grooves between the material-dispensing plates 33 of adjacent material-dispensing rollers change continuously, so that the materials will not be concentrated and accumulated, thus avoiding material congestion.

[0036] 4. The material is transported to the downstream equipment through the discharge port at the bottom of the activation bin 2.

[0037] The silo activator in this embodiment breaks the symmetry between adjacent silo rollers by using different numbers of silo plates of the first silo roller 31 and the second silo roller 32 and arranging the silo plates at equal intervals, ensuring that the relative positions of the grooves change continuously during the rotation process, thereby effectively preventing the material from arching and clogging, and is suitable for large silo design, reducing the frequency of staff feeding, and improving the continuity and stability of production. At the same time, the inclined surface design of the silo and the arrangement of the inspection door further enhance the structural stability and maintenance convenience of the silo.
