Technical field

The present invention relates to a silo structure and a silo of a silo. Background technique

A silo is a warehouse for storing bulk materials. Silos can be broadly divided into agricultural silos and industrial silos. Among them, industrial silos are used to store bulk materials such as coal, cement, salt, and sugar. For silos that store coal, it is necessary to further strengthen the silo structure of the silo.

In the prior art, a channel type bottom is usually employed. Specifically, the channel-shaped bottom of the channel from the base cap to the conical funnel of the silo is filled with a filler, the surface of the funnel is cast with a reinforced concrete structural layer, and the reinforced concrete structural layer is not integrally connected with the silo wall of the silo. This silo has a low stress performance and can carry heavier materials, but the amount of filler used is large, which increases the silo's own weight and directly increases the basic requirements.

Therefore, existing silos cannot provide sufficient strength support and light weight at the same time. Summary of the invention

The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that The specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the present invention, the orientation words such as "up, down, left, and right" as used generally refer to the above, below, left, and right as shown in the accompanying drawings; "refers to the inside and outside of the outline of each component itself.

Further, in the present invention, "taper" means an inclination angle of a slope of (a pyramid) with respect to a horizontal plane, or a ratio of a diameter difference between a top surface and a bottom surface of a circular table to a height of a circular table.

The bottom structure of the present invention includes a cylindrical wall portion 10, a ring beam 20, a support wall 40, a support column 50, and a discharge funnel 30 having an inlet and an outlet, the cylindrical wall portion 10 including the cylindrical wall 11 and along the cylindrical wall 11 a wall column 12 disposed at an inner circumferential interval, the cylinder wall 11, the wall column 12, the support wall 40 and the support column 50 are respectively supported on a foundation, and an outer edge of the discharge funnel 30 passes through The ring beam 20 is supported on the wall column 12, and the discharge funnel 30 is also supported on the foundation by the support wall 40 and the support column 50.

The discharge funnel 30 is supported on the foundation by a ring beam 20, a wall column 12 (wherein a suitable number and spacing of the wall columns 12 can be provided as needed), and has sufficient support strength. Therefore, the discharge funnel 30 can be formed using various lightweight structures to reduce the weight of the silo.

Additionally, the bottom structure may include a plurality of discharge funnels 30 such that it may be selectively discharged through one or more discharge funnels 30. Preferably, in the embodiment shown in Fig. 1, the plurality of discharge funnels 30 are arranged in two columns, and a plurality of the discharge funnels 30 are arranged in each column. Three columns per column are shown in Figure 1, but it will be understood by those skilled in the art that an appropriate number of discharge funnels 30 can be placed in each column as desired.

Further, in order to facilitate the conveyance of the discharge, a belt machine (not shown) may be provided below each of the hoppers 30. The belt speed of the belt conveyor can be set according to the number of open discharge funnels 30. In other words, the greater the number of open discharge funnels 30, the faster the belt speed and vice versa.

In order to further strengthen the support of the discharge funnel 30, the bottom structure may further comprise a support column 50, the discharge funnel 30 being supported on the foundation by the support column 50 at the position of the outlet On.

Further, preferably, an activation feeder is disposed below the outlet of each discharge funnel 30 to uniformly or quantitatively output the material from the discharge funnel 30.

Further, the inlet of the discharge funnel 30 may have a non-central symmetrical shape, preferably a rectangular shape or an elliptical shape. By setting the inlet of the non-centro-symmetric shape, the flow rate and velocity of the material falling into the discharge funnel 30 along the different contour edges of the inlet during the discharge may be different, so that the material falling fast on the one hand may collide with the material with a slow drop. In order to make the material with slow drop speed up, on the other hand, the material will flow to the edge of the contour with large flow, thus alleviating the congestion of the smaller contour edge. Therefore, it is possible to prevent the discharge funnel 30 of the present invention from being clogged.

The preferred structure of the discharge funnel 30 of the present invention will now be described.

In an embodiment of the present invention, as shown in FIGS. 2 and 3, the discharge funnel 30 includes a funnel plate including a first cone plate 31 and an outer end from the first cone plate 31. An outer extending flat plate 32, the first cone plate 31 being supported by the support wall 40 and the support post 50, the outer edge of the outer flat plate 32 being supported on the wall post 12 by the ring beam 20 An outer packing portion 33 is formed on the outer flat plate 32.

Preferably, the first cone plate 31 is a plurality of plane cone plates, and the tapers of the at least two first cone plates 31 are different (that is, at least two different tapers in the plurality of first cone plates 31). For example, in the embodiment shown in Figures 2 and 3, the funnel plate includes a rectangular inlet and an outlet to include four first cone plates 31, wherein the opposing two first cone plates 31 have the same taper (tilt) The same angle). As can be seen from FIG. 2 and FIG. 3, the angle between the two pairs of first cone plates 31 is different, so that when the discharge funnel 30 is opened, the material falling along the adjacent first cone plate 31 is caused by the first cone. The plates 31 have different tapers and different speeds. In other words, in the same horizontal section, the materials at different positions have different falling speeds, and the faster materials will affect the slower falling of the materials, thereby avoiding the possibility of clogging the discharge funnel 30 during discharging. Alternatively, the four first cone plates 31 may each have a different taper, as well as avoiding clogging.

The size of the space cast by the filler 33b depends on the taper of the second cone plate 33a. Therefore, preferably, as shown in Figs. 2 and 3, the taper of the first cone plate 31 is larger than the taper of the second cone plate 33a. With this arrangement, on the one hand, the filler 33b can be reduced, thereby reducing the dead weight of the discharge funnel 30; on the other hand, the material falling along the second cone plate 33a and the first cone plate 31 can be abruptly accelerated during the falling process. This acceleration can act like a "sucking" material down to avoid material blockage.

It can be understood that the funnel flap includes a plurality of first cone plates 31, and each of the first cone plates 31 is connected to a second cone plate 33a. In order to generate the above-mentioned "suction" effect, the taper of one first cone plate 31 is greater than the taper of the second cone plate 33a connected thereto, but the taper of the other one or more first cone plates 31 may be made larger than the taper thereof. The taper of the second cone plate 33a. In the embodiment shown in Figures 2 and 3, the inlet and outlet are formed in a rectangular shape, and the funnel flap has four first cone plates 31, each of which has a greater taper than the second cone plate connected thereto. The taper of 33a.

In the above description, the first cone plate 31 and the second cone plate 33a are both planar cone plates such that the discharge funnel 30 includes a first cone portion and a second cone portion that are continuously disposed from the inlet to the outlet. And the inner cone space of the first cone portion and the second cone portion is formed in a truncated cone shape. However, the first cone plate 31 and the second cone plate 33a may also be curved cone plates and the taper of the first cone plate 31 is greater than the taper of the second cone plate 33a connected thereto, so that the first cone portion and the second cone portion The inner cone space of the bucket portion is formed into a truncated cone shape or a horn shape (the taper of the curved cone plate gradually becomes smaller from the inlet to the outlet). Alternatively, the first cone plate 31 and the second cone plate 33a may each include a curved cone plate and a planar cone plate and the taper of the first cone plate 31 is greater than the taper of the second cone plate 33a connected thereto, thereby making the first The inner cone space of the cone portion and the second cone portion is formed into an irregular horn shape.

In addition, an intermediate plate may be formed between the first cone plates 31 of the two adjacent discharge funnels 30 34. An intermediate filler portion 35 may be formed on the intermediate plate 34. With this arrangement, the joint strength between the adjacent discharge funnels 30 can be enhanced, so that the plurality of discharge funnels 30 are jointly reinforced. Preferably, the intermediate packing portion 35 includes a flap 35a extending from the adjacent two first cone plates 31, and a space between the flap 35a and the intermediate flat plate 34 is poured by the filler 33b. Wherein, the flap 35a may also have a taper smaller than that of the first cone plate 31 to create a "suction" effect.

It can be understood that, in the present embodiment, the discharge funnel 30 of the present invention includes the first cone portion defining the inner cone space thereof by the plurality of first cone plates 31 and the second cone plate 33a from the inlet to the outlet. And the flap 35a defines a second cone portion of its inner cone space. In other words, in the first cone portion, the side cone plate defining the inner cone space is the first cone plate 31; in the second cone portion, the side cone plate defining the inner cone space is the second cone plate 33a and Folding plate 35a. Therefore, the taper of at least two side cone plates defining the inner cone space of the first cone portion may be different (ie, the tapers of at least two first cone plates 31 are different), and/or the second cone portion may be defined. At least two of the side cone plates of the inner cone space (including the second cone plate 33a and the flap 35a) have different tapers. In the second cone portion, the number of the second cone plates 33a and the flaps 35a may vary depending on the arrangement position of the discharge funnel 30. For example, in the two discharge funnels 30 at the position shown in Fig. 2, each of the discharge funnels 30 has two second cone plates 33a and two flaps 35a, so that two second cone plates 33a and two can be made. Any two or more of the flaps 35a have different tapers.
