Description

TECHNICAL FIELD

[0001] The utility model relates to power plant feeding equipment technical field, especially relates to a ground pushes away roll material bin unloader. BACKGROUND

[0002] In the biomass power plant, solid waste power plant and coal power plant blending feeding system, the push roll material bin unloader is the important equipment of material conveying link, and its performance directly influences the running efficiency and stability of the whole power plant feeding system.

[0003] The conventional push roll material bin unloader is mainly composed of a material bin, a push roll and a transmission device. Its working principle is that the material is stored in the material bin, the transmission device drives the push roll to rotate, the push teeth on the push roll push the material, and the material is discharged from the material bin outlet, thereby realizing the unloading process.

[0004] However, in practical application, the existing conventional push roll material bin unloader has the following obvious defects:

[0005] I. Poor processing capacity of strip-shaped material

[0006] In the biomass power plant, strip-shaped materials such as orange gourd are often processed. These strip-shaped materials are prone to the following problems in the conventional push roll material bin unloader:

[0007] Frequent plugging phenomenon: due to the shape characteristics of the strip-shaped material, they are prone to entangle and knot with each other during falling. For example, when the push roll rotates to push the material, the strip-shaped material may be entangled on the push teeth, or intertwined together, forming a large material lump, which hinders the normal falling of the subsequent material, causes the material to accumulate at the material bin outlet, and the unloading is not smooth. This plugging phenomenon not only affects the continuity of unloading, but also may cause the running interruption of the whole feeding system, which needs frequent manual cleaning, increases the maintenance cost and workload.

[0008] The problem of material bridging and suspension is prominent: the strip-shaped material is also prone to form a bridging and suspension phenomenon in the material bin. When the material accumulates in the material bin, it may form an arch structure at some positions, similar to a bridge, and the material cannot fall smoothly to the area that can be reached by the push roll by relying on its own gravity. This makes the push roll unable to effectively push the material, causing the material to be difficult to take, which seriously affects the production efficiency of the feeding system, and may affect the normal power generation operation of the power plant.

[0009] II. Unreasonable structure design aggravates the unloading problem

[0010] The arrangement form of the pushing roller and the pushing teeth is single: the arrangement form of the pushing roller and the pushing teeth of the conventional pushing roller stock bin unloader is not flexible enough, and is usually uniformly distributed or simply regularly arranged. Such arrangement cannot effectively disperse and guide the materials when facing materials with complex shapes, especially strip-shaped materials. For example, when the pushing teeth push the materials, due to the regular distribution of the pushing teeth, the materials may be accumulated in some areas, while the materials are sparse in other areas, further exacerbating the problems of material blockage and uneven distribution of materials, affecting the stability and uniformity of unloading.

[0011] In addition, the bin plate of the conventional stock bin is designed in a symmetrical manner. Such design cannot provide good material flowability guidance when processing materials with different characteristics. The simultaneous sliding of the materials on both sides is extremely easy to collide and block at the discharge port. In particular for strip-shaped materials, a single bin plate angle cannot effectively promote the materials to slide to the pushing roller area, is easy to cause the materials to be retained on the bin plate, increases the possibility of material bridging and suspension, and is not conducive to uniform material conveying, so that the materials are prone to appear in a discontinuous manner during the unloading process, and cannot meet the requirements of the power plant feeding system for efficient and stable material conveying.

[0012] In summary, due to the limitations of the working principle and structural design of the existing pushing roller stock bin unloader, it is difficult to achieve stable and uniform conveying of materials when processing strip-shaped materials in the biomass power plant, solid waste power plant and coal power plant blending feeding system, which seriously affects the normal operation and production efficiency of the power plant feeding system. Therefore, a new technical solution is needed to solve these problems to improve the performance and applicability of the pushing roller stock bin unloader. Content of the utility model

[0013] The technical problem to be solved by the utility model is to solve the problems of material blockage and material bridging and suspension when the conventional pushing roller stock bin unloader processes strip-shaped materials such as luffa in the biomass, solid waste and coal power plant blending feeding system, to realize stable and uniform conveying of materials by improving the arrangement form of the pushing roller and the pushing teeth and adjusting the angles of the two sides of the bin plate, so as to meet the requirements of the power plant feeding system for efficient and stable conveying of materials.

[0014] The technical solution adopted by the utility model to solve the technical problem is:

[0015] The ground pushing roller stock bin unloader comprises a stock bin, a pushing roller, a reduction motor and a workbench. The stock bin is fixed in the middle of the workbench, the discharge port thereof penetrates through the workbench downward and is connected with a lower device. The pushing roller is provided with two, and the two are installed in parallel with a height difference above the discharge port of the stock bin. The reduction motor is provided with two, and is fixed on the workbench and connected with one end of the pushing roller respectively to drive the rotation of the pushing roller. The pushing roller comprises a roller shaft and a plurality of pushing teeth, and the pushing teeth are arranged on the roller shaft in a staggered manner.

[0016] Further preferred technical solutions, the top surface of the bin is rectangular feed port, the bottom surface is rectangular discharge port, its left and right panels are symmetrical to each other, and the front and rear panels are respectively different from the horizontal plane.

[0017] Further preferred technical solutions, the front panel of the bin is 60° from the horizontal plane, and the rear panel of the bin is 70° from the horizontal plane.

[0018] Further preferred technical solutions, the speed reducer is arranged on both sides of the bin, and is connected to the push roller through a shaft coupling.

[0019] Further preferred technical solutions, both sides of the workbench are provided with a ladder, which is convenient for maintenance personnel to overhaul.

[0020] Further preferred technical solutions, the shaft center height of the lower position of the push roller is consistent with the bottom end height of the roller shaft of the higher position of the push roller.

[0021] Further preferred technical solutions, both ends of the push roller are fixed on the workbench through a bearing seat.

[0022] The beneficial effects of the utility model are:

[0023] 1, the arrangement form of the push roller and the push gear plate is improved

[0024] Reduce material jam and bridge: in the scheme, the push roller is arranged in different positions, and the unique design makes the material not easy to jam in the conveying process due to being in the same plane. For example, when the strip-shaped material such as luffa enters the bin, due to the height difference of the push roller, the material will be gradually pushed under the action of the push roller at different heights, avoiding the situation that the material is jammed in the same horizontal position, thereby effectively reducing the occurrence of the bridge phenomenon. The material can pass through the push roller area more smoothly, ensuring the continuity of unloading and improving the stability of the feeding system.

[0025] Enhance the dispersibility of the material: the push roller and the push gear are irregularly distributed. This arrangement breaks the limitation of traditional regular arrangement. When the push roller rotates, the irregularly distributed push gears can push and stir the material from different angles and positions. For strip-shaped materials of different shapes, the staggered irregular push gears can better disperse the material, so that it is not concentrated in a certain area, but evenly distributed around the push roller, and then stably conveyed out. This advantage effectively solves the problem of uneven distribution of material and easy blockage caused by regular arrangement of push gears in conventional unloader, and improves the uniformity and efficiency of material conveying.

[0026] 2, the angle adjustment of the two sides of the bin plate

[0027] Optimize material flow: the design of different angles on both sides of the bin plate can better guide the material to slide to the poking roller area according to the characteristics and flow rules of the material. Different angles of the bin plate can adapt to the accumulation of the material at different positions in the bin. For example, when the strip-shaped material is accumulated in the bin, the bin plates with different angles on both sides can make the material slide in a more favorable direction under the action of gravity, avoiding the accumulation of the material on the bin plate, reducing the possibility of material bridging and suspension, and improving the flowability of the material and the smoothness of the unloading.

[0028] Adapt to the characteristics of various materials: the adjustable bin plate angle design enables the unloader to adapt to the characteristics of various materials in the biomass power plant, solid waste power plant and coal power plant blending feeding system. The shape, size and humidity of different materials will affect their flowability in the bin, and different bin plate angles can be optimized according to the actual material conditions to ensure that various materials can smoothly slide to the poking roller area in the bin, realize stable and uniform conveying, and enhance the versatility and adaptability of the unloader.

[0029] In summary, the patent solves the problems of material blocking and bridging of the conventional poking roller bin unloader when handling strip-shaped materials from multiple aspects by improving the arrangement of the poking roller and the poking teeth and adjusting the angles on both sides of the bin plate, realizes stable and uniform conveying of the material, and has significant technical advantages and application value.

[0034] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0035] AsFigure 1 As shown in the figure, this embodiment discloses a ground roller hopper unloader, the specific implementation structure of which includes: a hopper 1, a roller 2, a reduction motor 3, and a worktable 4. The worktable 4 serves as the supporting foundation for the entire device, and the hopper 1 and the reduction motor 3 are both fixedly installed on the worktable 4. The hopper 1 is fixed in the middle of the worktable 4, and its discharge port extends downward through the worktable 4 to connect with the next-level device.

[0036] Regarding the design of the workbench:

[0037] like Figure 1 As shown, the workbench 4 can be a trapezoidal frame platform welded from H-beams. Ladders 7 are symmetrically installed on both sides of the workbench 4 for maintenance by staff. The workbench 4 has internal reinforcing beams to improve its load-bearing capacity.

[0038] Regarding the design of the silo:

[0039] like Figure 2 As shown, the top surface of the hopper 1 is a rectangular inlet, and the bottom surface is a rectangular outlet. Its left and right panels are symmetrical, and the front panel 11 and the rear panel 12 have different angles with the horizontal plane. In the specific design, the angle between the front panel 11 of the hopper 1 and the horizontal plane is 60°, and the angle between the rear panel 12 of the hopper 1 and the horizontal plane is 70°.

[0040] Design of the misaligned shift roller:

[0041] like Figure 2 As shown, two rollers 2 are provided in the hopper 1, specifically: a first roller 21 and a second roller 22; the first roller 21 and the second roller 22 are installed side by side above the discharge port of the hopper 1 with staggered heights. Among them, the first roller 21 is the high-position roller and the second roller 22 is the low-position roller, and the axis height of the low-position roller is the same as the bottom height of the roller shaft of the high-position roller.

[0042] Both ends of the two rollers 2 are fixed to the worktable 4 by bearing seats 5.

[0043] like Figure 3 As shown, the roller 2 includes a roller shaft 211 and a plurality of teeth 222. The teeth 222 are arranged alternately on the roller shaft 211.

[0044] Design of the drive structure:

[0045] like Figure 1 and 2 As shown, note Figure 1In order to clearly show the connection structure of the roller 2 and the reduction motor 3, the high-position roller, that is, the first roller 21 is omitted, only the connection structure of the second roller 22 and the reduction motor 3 corresponding to the first roller 21 are shown, but because the connection modes of the first roller 21 and the second roller 22 are the same, the expression of the connection principle is not affected.

[0046] The reduction motor 3 is provided with two, and the two reduction motors 3 are respectively connected with the first roller 21 and the second roller 22 through the shaft coupling 6, and then drive the two rollers to rotate towards each other.

[0047] Working principle:

[0048] After the material enters the silo from the top feed inlet, it is guided by the asymmetric bin plate, and the design of different angles on both sides of the bin plate can better guide the material to slide to the roller area according to the characteristics and flow law of the material, so that the feed flow rates on the front and rear sides are different, and then the shearing action of the two staggered step rollers cuts off the wound strip-shaped object. Due to the height difference of the rollers, the material will be gradually pushed under the action of the rollers at different heights, avoiding the accumulation and jamming of the material at the same horizontal position, thereby effectively reducing the occurrence of the bridging phenomenon.

[0049] In addition, the roller teeth are irregularly distributed in a staggered manner, which breaks the limitation of the traditional regular arrangement. When the roller rotates, the irregularly distributed teeth can push and stir the material from different angles and positions. For strip-shaped materials of different shapes, the staggered irregular teeth can better disperse the material, so that it is not concentrated in a certain area, but uniformly distributed around the roller, and then stably conveyed out.
