Description

Technical Field

[0001] The utility model relates to the field of bulk grain storage, in particular to an assembled shallow silo capable of realizing transverse ventilation. Background Art

[0002] The granary is the main facility for grain storage and processing. Different from ordinary civil buildings, the construction of the granary needs to meet the requirements of various functions such as ventilation and heat insulation during the operation and storage of grain. As the mainstream silo type in the current granary construction, the construction method of the shallow silo is mainly the cast-in-place reinforced concrete structure, which does not meet the requirements of the current construction industry for green, industrialized and informatized development. It has the disadvantages of high labor cost, low material utilization rate, large noise and dust pollution at the construction site, and long construction period.

[0003] In the prior art, there are also assembled shallow silos built with precast slabs. However, this kind of assembled shallow silo still adopts the traditional vertical ventilation method, that is, ventilation ducts are arranged at the bottom of the silo. When it is necessary to ventilate and dissipate heat from the bulk grain, air is introduced into the ventilation ducts, and the air flows through the grain pile from bottom to top, that is, the so-called vertical ventilation, so as to realize the ventilation and heat dissipation of the whole grain pile. The existing ventilation and heat dissipation form has the following problems: the height of the shallow silo is relatively high. When ventilating and dissipating heat vertically, the air flow needs to pass through the whole height of the grain pile from bottom to top, resulting in a relatively large ventilation resistance; in addition, the installation area of the ventilation ducts is limited, resulting in a small air outlet area. Overall, the effective ventilation and heat dissipation of the grain pile cannot be realized. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an assembled shallow silo capable of realizing transverse ventilation, so as to solve the problem in the prior art that the ventilation and heat dissipation effect of the grain pile is poor due to only relying on the vertical ventilation upward through the ventilation ducts at the bottom of the grain pile.

[0005] To solve the above technical problems, the technical solution of an assembled shallow silo capable of realizing transverse ventilation in the utility model is as follows:

[0006] A prefabricated shallow circular silo capable of achieving transverse ventilation comprises a silo wall and a silo roof arranged on the top of the silo wall, wherein the silo wall is composed of a plurality of silo wall layers sequentially arranged in an up-and-down direction, each silo wall layer comprises a plurality of arc-shaped silo wall panels sequentially arranged in a circumferential direction, in each silo wall layer, the arc-shaped silo wall panels at corresponding positions are vertically arranged in the up-and-down direction, two adjacent arc-shaped silo wall panels in the circumferential direction and two adjacent arc-shaped silo wall panels in the up-and-down direction are connected by bolts, annular prestressed tendons are arranged between the arc-shaped silo wall panels in the same silo wall layer, a plurality of vertical ventilation grooves extending in the up-and-down direction are arranged on the inner side of the silo wall, the vertical ventilation grooves are located on the inner side of the prestressed tendons, the vertical ventilation grooves cross a corresponding group of vertically arranged arc-shaped silo wall panels in the up-and-down direction, a loose grain baffle is arranged at the notch of the vertical ventilation groove, and baffle vents are arranged in an array on the loose grain baffle.

[0007] Furthermore, the vertical ventilation slots are arranged in pairs, and the two vertical ventilation slots in each pair of vertical ventilation slots are symmetrically arranged on both sides of the axis of the warehouse wall.

[0008] Furthermore, the bottom of the shallow circular silo is provided with ventilation cages which are radially distributed with the center of the bottom of the silo as the center, and the bottoms of the two vertical ventilation slots in each pair of vertical ventilation slots are connected to the two ends of the corresponding ventilation cages.

[0009] Furthermore, each arc-shaped warehouse wall plate has bolt connection grooves at the four corners, and bolt through holes for installing corresponding bolts are arranged on the corresponding side groove walls of the bolt connection grooves.

[0010] Furthermore, in the circumferential direction, there is at least one vertically arranged arc-shaped warehouse wall plate between two adjacent vertical ventilation slots, and each vertical ventilation slot is located at a circumferentially middle position on the corresponding arc-shaped warehouse wall plate.

[0011] The beneficial effects of the utility model are as follows: the shallow round silo of the utility model adopts an assembled structure, and the arc-shaped silo wall panels are prefabricated panels prefabricated in the factory. During assembly, two adjacent arc-shaped silo wall panels in the circumferential direction and two adjacent arc-shaped silo wall panels in the vertical direction are connected by bolts. Annular prestressed tendons are arranged between the arc-shaped silo wall panels in the same silo wall layer, and the connection strength between the arc-shaped silo wall panels in the same silo wall layer is ensured by the prestressed tendons. In each silo wall layer, the arc-shaped silo wall panels at corresponding positions are arranged vertically in the vertical direction, so that each arc-shaped silo wall panel is vertically arranged in the vertical direction. After being assembled, the ventilation grooves on the inner wall of the silo wall plate form a vertical ventilation groove that spans a corresponding group of vertically arranged arc-shaped silo wall plates in the up and down direction. When the grain pile needs to be ventilated and dissipated, air is introduced into the vertical ventilation groove, and the air passes through the baffle vent along the radial direction of the shallow circular silo, that is, horizontally, into the grain pile. Compared with vertical ventilation, the ventilation path is shortened and the ventilation resistance is reduced. At the same time, more vertical ventilation grooves can be arranged in the circumferential direction, and the higher length of the vertical ventilation grooves is combined to increase the ventilation area, thereby comprehensively improving the ventilation and heat dissipation effect of the grain pile.

[0020] For the convenience of understanding the present utility model, the present utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present utility model more thorough and comprehensive.

[0021] It should be noted that unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model.

[0022] The utility model is a kind of assembled shallow silo that can realize transverse ventilation. Figures 1 - 6 As shown: it includes a silo bottom foundation 1, a silo wall 2 and a silo roof 3 arranged on the top of the silo wall. The silo wall 2 and the silo roof 3 are prefabricated structures, and the silo bottom foundation 1 can be cast on site.

[0023] The warehouse wall 2 is composed of a plurality of warehouse wall layers 8 sequentially arranged in the up-down direction, and each warehouse wall layer 8 includes a plurality of arc-shaped warehouse wall panels 2.1 sequentially arranged in the circumferential direction. In each warehouse wall layer, the arc-shaped warehouse wall panels 2.1 at corresponding positions are vertically arranged in the up-down direction, that is to say, in the upper and lower warehouse wall layers, the corresponding arc-shaped warehouse wall panels are not staggered, and the arc-shaped warehouse wall panels of the upper warehouse wall layer are located directly above the arc-shaped warehouse wall panels of the lower warehouse wall layer, and the arc-shaped warehouse wall panels are prefabricated in the factory.

[0024] Each arc-shaped warehouse wall plate 2.1 has a bolt connection groove 2.5 at the four corners, and a bolt through hole 6 for realizing the corresponding bolt insertion is provided on the corresponding side groove wall of the bolt connection groove 2.5. The connection between two adjacent arc-shaped warehouse wall plates in the circumferential direction and two adjacent arc-shaped warehouse wall plates in the vertical direction is realized by inserting bolts 2.6 in the bolt through holes 6. For example, two adjacent arc-shaped warehouse wall plates in the vertical direction are connected by vertical bolts, and two adjacent arc-shaped warehouse wall plates in the circumferential direction are connected by circumferential bolts. The nuts connected to the vertical bolts and the circumferential bolts are located in the corresponding bolt connection groove 2.5.

[0025] Each arc-shaped warehouse wall plate 2.1 is also provided with a prestressed tendon through hole 7, and an annular prestressed tendon 2.3 for strengthening the connection between the arc-shaped warehouse wall plates in the same warehouse wall layer is installed in the prestressed tendon through hole of each warehouse wall layer. In this embodiment, each warehouse wall layer has three prestressed tendons 2.3 spaced apart in the up-and-down direction.

[0026] A plurality of vertical ventilation slots 2.2 extending in the up-down direction are arranged on the inner side of the silo wall. The vertical ventilation slots 2.2 are located on the inner side of the prestressed tendons. The vertical ventilation slots cross a corresponding group of vertically arranged arc-shaped silo wall panels 2.1 in the up-down direction. A loose grain baffle 4 is arranged at the notch of the vertical ventilation slot. Baffle air outlets 5 are arranged in an array on the loose grain baffle 4. In this embodiment, the loose grain baffle is a U-shaped structure. The loose grain baffle 4 is buckled on the vertical ventilation slots 2.2. The vertical ventilation slots 2.2 are arranged in pairs, and the two vertical ventilation slots in each pair of vertical ventilation slots are symmetrically arranged on both sides of the silo wall axis.

[0027] In the circumferential direction, there is an arc-shaped bulkhead plate arranged vertically between two adjacent vertical ventilation grooves, and each vertical ventilation groove is located at the middle position in the circumferential direction on the corresponding arc-shaped bulkhead plate. That is to say, among the arc-shaped bulkhead plates, for two adjacent arc-shaped bulkhead plates in the circumferential direction, a vertical ventilation groove is provided on the inner wall of one arc-shaped bulkhead plate, and no vertical ventilation groove is provided on the inner wall of the other arc-shaped bulkhead plate. The vertical ventilation groove is located inside the prestressed tendon, and the groove depth of the vertical ventilation groove does not exceed one-third of the wall thickness of the arc-shaped bulkhead plate.

[0028] On the bottom foundation of the shallow silo, there is a ventilation duct 9 radially distributed with the center of the bottom foundation as the center. The number of ventilation ducts 9 is the same as the number of pairs of vertical ventilation grooves, and the bottoms of the two vertical ventilation grooves in each pair of vertical ventilation grooves are connected to the two ends of the corresponding ventilation duct 9.

[0029] The middle parts of the ventilation ducts are cross-connected. During use, the air outlet of the fan is connected to at least one of the ventilation ducts. When it is necessary to ventilate and dissipate heat from the grain pile on the upper side of the bottom foundation, the fan sends air into the ventilation duct. A part of the air flow directly passes through the grain pile from bottom to top through the vertical ventilation holes on the ventilation duct to form vertical ventilation, and a part of the air flow flows to the corresponding vertical ventilation groove through the ventilation duct. In the vertical ventilation groove, it radially passes through the grain pile along the baffle ventilation opening on the outer branch to form transverse ventilation. The grain pile is ventilated and dissipated heat through the combined action of transverse ventilation and vertical ventilation, accelerating the ventilation and heat dissipation effect of the grain pile.

[0030] In other embodiments of the present invention, the ventilation duct may not be provided. At this time, the fan can be directly connected to each vertical ventilation groove, and the grain pile is ventilated and dissipated heat only through the transverse ventilation realized by the vertical ventilation groove.

For example, for the term "connected", it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, or it can be the internal communication of two components or the interaction relationship between two components. Therefore, unless otherwise clearly limited in this specification, those skilled in the art can understand the specific meaning of the above terms in the present invention according to specific circumstances.
