Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

As mentioned in the background art, the conventional coal storage system has a strip coal yard which is most commonly used in domestic thermal power plants, but the coal storage system has a limited stacking height, generally 12m to 15m, and is naturally stacked in a scattered state, so that the coal storage amount per unit area is relatively small, and if the coal storage amount needs to be increased, the floor area of the coal yard needs to be increased. The occupied area is large, and the space utilization rate is low.

Therefore, how to increase the pile height of the coal storage system and improve the space utilization rate of the coal storage site becomes an improvement direction of the application. In order to achieve the purpose, the application provides a coal storage system, and the basic concept is that a bottom plate and a plurality of layers of guide plates are sequentially arranged from bottom to top in an inclined mode, at least one guide unit is arranged on each guide plate, the guide units arranged on the guide plates are gradually increased from top to bottom, a blanking door is arranged in the extending direction of each guide unit, incoming materials on the blanking door are opened when certain weight is accumulated, and therefore cloth is distributed, the blanking doors on each layer of guide plates are sequentially opened, and cloth is stably distributed on the bottom plate and each layer of guide plates.

Referring to fig. 1 to 3, a detailed structure of the coal storage system of the present invention is shown.

As shown in fig. 1, the coal storage system 1 comprises a bottom plate 11, a striker plate 13 and a plurality of layers of guide plates 12, wherein the plurality of layers of guide plates 12 are arranged above the bottom plate 11, the bottom plate 11 and the plurality of layers of guide plates 12 are arranged obliquely from high to low, and the striker plate 13 is mounted at one lower end of the bottom plate 11 and the plurality of layers of guide plates 12; the number of the guide units 121 included in the plurality of layers of the guide plates 12 is increased from top to bottom, each layer of the bottom plate 11 and the guide plate 12 includes at least one guide unit 121, each guide unit 121 is provided with a blanking door 1221 at an interval, the blanking door 1221 is provided with a first switch mechanism 1222, and the first switch mechanism 1222 keeps the blanking door 1221 closed when the force is smaller than a first set value.

The material is distributed from the guide plate 12 at the uppermost layer, when the stress of the first blanking door 1221 arranged at the lower end of the guide plate 12 at the uppermost layer is greater than or equal to a first set value, the first switch mechanism 1222 of the blanking door 1221 is opened, the material falls on the guide plate 12 at the lower layer and is stacked on the guide plate 12 at the lower layer, when a certain weight is stacked, the blanking door of the guide plate 12 at the lower layer is opened until the material falls on the bottom plate 11, because the blanking door 1221 is not arranged on the bottom plate 11, the material is directly stacked on the bottom plate, the blanking door 1221 on the guide plate 12 at the uppermost layer is opened from the lower end to the higher end in sequence, and the material is distributed from the lower end to the higher end on the bottom plate until the higher end of the bottom. The guide plates are distributed on the guide plates below the guide plates in the above manner, and finally, the highest ends of the guide plates on the uppermost layer are distributed with the materials.

The striker plate 13 is the triangle-shaped structure, and the multilayer deflector is installed from the top to the bottom of triangle-shaped structure in proper order, and the installation direction of multilayer deflector 12 is parallel to each other. The supplied materials can be uniformly distributed from low to high, and the whole material is piled into a triangular shape, so that the material is stable and cannot fall off.

As shown in fig. 2, each of the guiding units 121 includes two support plates, and the two support plates are connected in sequence to form a V-shaped groove. The support plates on the two sides limit the incoming materials in the grooves, so that the incoming materials are not easy to drop when moving in the guide unit 121. On the other hand, the guide plate 12 composed of the guide unit 121 in the structural form has high strength, saves materials and is convenient to process.

The first set value is determined by the distance between the two layers of guide plates 12, and the larger the distance, the more the incoming material can be carried, so that the first set value is not a fixed value, and is generally measured by the stacking height, and when the stacking height is 5-10cm away from the guide plate on the upper layer, the first switch mechanism 1222 is turned on.

As shown in fig. 3, the first switch mechanism 1222 includes a bracket 12221 and a first torsion spring 12222, the bracket 12221 is fixed to the back of the guide unit 121, the first torsion spring 12222 is sleeved on the bracket, and torsion arms at two ends of the first torsion spring 12222 are engaged with the blanking door 1221. By adjusting the stiffness coefficient of the first torsion spring 12222, the required magnitude of the first setting value can be easily satisfied with high accuracy.

In this embodiment, the coal storage system further includes a discharging system 3, and the discharging system 3 includes a discharging hole 31 disposed at a lower end of each of the guiding units 121. The discharge port 31 can discharge the material to a desired position, but the discharge speed is slow because the discharge port 31 accumulates more material.

Discharging system 3 still includes agitating unit 32, agitating unit 32 is along keeping away from on the direction of discharge gate 31 locates the guide unit 121, agitating unit 32 includes driving motor 321 and auger 322, auger 322 is including installation axle 3221 and helical blade 3222, helical blade 3222 is located on the installation axle 3221, driving motor 321's output shaft with the linkage of installation axle 3221.

Drive auger 322 through driving motor 321 and rotate, stir the material on the bottom plate 11 and scatter, simultaneously because helical blade 3222 has the guide effect, the material can be transmitted to discharge gate 31 along helical blade 3222's soon, has solved because discharge gate 31 material more has the slow problem of pay-off.

It should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
