Cement raw material homogenizing storehouse silo constraint structure and cement raw material homogenizing storehouse

Abstract

This utility model provides a constraint structure for a cement raw material homogenization silo and a cement raw material homogenization silo, belonging to the technical field of raw material homogenization silos for cement production. The constraint structure for the cement raw material homogenization silo includes a silo, with a plurality of constraint members, which are sleeved on the outer wall of the silo at the discharge boundary position. Connecting members are arranged between two adjacent constraint members to sequentially bond the constraint members together to form an integral structure. This utility model sets constraint members at corresponding positions on the cross-section of the homogenization silo, and uses connecting members to bond an appropriate number of constraint members together. The multiple bonded constraint members are coaxially sleeved on the outside of the silo, so that the constraint members are located at the discharge boundary position of the silo. This can support the outside of the silo, thereby improving the compressive strength of the silo and preventing surface cracking caused by uneven stress on the silo, thus improving the service life of the silo.

Description

Technical Field

[0001] This utility model relates to the technical field of raw material homogenization silos for cement production, specifically to a silo constraint structure for a cement raw material homogenization silo and a cement raw material homogenization silo. Background Technology

[0002] Raw meal homogenization silos primarily utilize the "funnel effect" (or rat hole effect) generated by air agitation and gravity to mix raw meal powder by cutting through as many layers of material as possible as possible as it falls downwards. Simultaneously, under the influence of different fluidizing air masses, varying degrees of fluidization and expansion occur along the parallel material surface within the silo; that is, some areas unload while others fluidize, resulting in a radial tilt of the material surface within the silo for radial mixing and homogenization. Raw meal homogenization silos mainly employ reinforced concrete circular silo structures, which generally consist of six parts: the superstructure, roof, walls, floor, supporting structure, and foundation. Existing homogenization silos use a diagonal unloading method, meaning only two unloading ports unload at a time, continuously unloading for 15 minutes before moving to the next set of unloading ports, following a specific pattern. Figure 1 The materials are unloaded sequentially as shown. Due to unloading at different locations, uneven stress occurs on the surface of the homogenization silo, particularly resulting in significant reverse bending forces at certain cross-sections (see reference). Figure 2 This uneven stress on the overall structure of the homogenization silo can cause deformation and cracks on the silo surface. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model utilizes connectors to link multiple constraint members together and fits them onto the outside of the silo to improve the silo's compressive strength and prevent surface cracking caused by large reverse bending forces on the homogenization silo section. The specific technical solution is as follows:

[0004] A cement raw material homogenization silo constraint structure includes a silo and further includes:

[0005] The constraint members are provided in plurality, and the plurality of constraint members are fitted onto the unloading boundary position on the outer wall of the silo; and

[0006] A connector is disposed between two adjacent constraint members and is used to sequentially bond several constraint members to form a whole structure.

[0007] Preferably, the constraint member is a steel plate, and the steel plate is an integrally formed cylindrical structure.

[0008] Preferably, at least two steel plates are provided.

[0009] Preferably, several steel plates are sequentially attached from the outer wall of the silo outwards.

[0010] Preferably, several of the steel plates are coaxially distributed along the silo axis.

[0011] Preferably, the connector is a structural adhesive, which is evenly applied between two adjacent steel plates.

[0012] Preferably, structural adhesive is provided between the innermost steel plate and the outer wall of the silo.

[0013] A cement raw material homogenization silo, wherein the outer wall of the silo is provided with the aforementioned constraint structure at the unloading boundary.

[0014] As can be seen from the above technical solutions, this utility model has the following beneficial effects:

[0015] By setting constraint members at corresponding positions on the cross-section of the homogenizing silo, and using connecting members to bond an appropriate number of constraint members together, and then coaxially sleeved the bonded constraint members on the outside of the silo, specifically placing the constraint members at the unloading boundary of the silo, the silo's exterior can be supported, thereby improving its compressive strength. Therefore, when the homogenizing silo unloads at different positions, it can avoid the formation of large reverse bending forces on the cross-section of the homogenizing silo, prevent uneven stress on the homogenizing silo, and make the stress on the silo more uniform. This avoids deformation caused by uneven stress on the silo, which can lead to surface cracking, and thus improves the service life of the silo. Attached Figure Description

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Before describing the technical solutions of each embodiment of the present invention in detail, the terms and terms involved will be explained. In this specification, components with the same name or the same reference numerals represent similar or the same structures and are limited to illustrative purposes.

[0021] Reference Figure 3A constraint structure for a cement raw material homogenization silo includes a silo 10, constraint members, and connecting members. The constraint members are arranged in multiple units, each fitted onto the unloading boundary of the outer wall of the silo 10. Connecting members are positioned between adjacent constraint members, allowing them to be sequentially bonded together to form a single integrated structure. In use, a suitable number of constraint members are selected and sequentially bonded together using the connecting members. Finally, the integrated constraint structure is fitted onto the unloading boundary of the silo 10, providing external support and improving its compressive strength. Therefore, when the homogenization silo unloads material at different locations, it avoids large reverse bending forces on the cross-section of the homogenization silo, preventing uneven stress distribution and ensuring more uniform stress distribution within the silo 10. This prevents surface cracking due to uneven stress distribution and extends the service life of the silo 10.

[0022] It should be noted that, in order to improve the local reinforcement effect of the silo 10, the constraint structure in this embodiment can be configured as multiple structures vertically distributed along the outer wall of the silo 10. This forms multiple annular bands in the area to be reinforced in the silo, thereby effectively reinforcing the unloading boundary of the silo 10. Furthermore, the length of each constraint structure extending axially along the outer wall of the silo is 20-40m, and the distance between two adjacent constraint structures along the axial direction of the silo 10 can be set to 500mm.

[0023] Reference Figure 3 As a preferred technical solution in this embodiment, the constraint member is a steel plate 20. The steel plate 20 is an integrally formed cylindrical structure, and at least two steel plates 20 are provided. Several steel plates 20 are sequentially bonded together by connectors from the outer wall of the silo 10 outwards. The thickness of the steel plate 20 can be set to 5mm. By bonding multiple steel plates 20 together through connectors 30, the overall hardness of the constraint member can be improved. Subsequently, multiple bonded cylindrical constraint members can be fitted onto the outside of the silo 10 to improve the hardness and compressive strength of the silo 10 and prevent cracks from appearing due to uneven stress on the outside of the silo 10.

[0024] Meanwhile, several steel plates 20 are coaxially distributed along the axial direction of the silo 10. In this way, the steel plates 20 of the cylindrical structure can form a composite cylinder. The composite cylinder is tightly attached to the outside of the silo 10 to improve the local strengthening effect of the silo 10.

[0025] It should be noted that the number of steel plates 20 can be set according to the actual local reinforcement requirements. At the same time, the position of the steel plates 20 on the outside of the silo 10 is not fixed. According to the material feeding requirements, the steel plates 20 can be placed on the parts of the silo 10 with greater stress to avoid the problem of cracks caused by uneven stress on the silo 10.

[0026] Reference Figure 3 In this preferred embodiment, the connector is structural adhesive 30. Structural adhesive 30 is evenly applied between two adjacent steel plates 20. Simultaneously, structural adhesive 30 is also applied between the inner surface of the innermost steel plate 20 and the outer wall of the silo 10. The thickness of the structural adhesive 30 application can be 1 mm. Structural adhesive 30 is a high-performance adhesive mainly used for bonding strong structural components. It features high strength, aging resistance, fatigue resistance, and corrosion resistance, and its performance remains stable within its expected lifespan. The type of structural adhesive 30 is not limited; for example, it can be epoxy structural adhesive, acrylic AB adhesive, silicone structural adhesive, etc. Adjacent steel plates 20 can be bonded by evenly applying the structural adhesive 30 between two steel plates 20 and pressing them together. Therefore, different numbers of steel plates 20 can be bonded as needed. In addition, structural adhesive 30 is applied to the inner surface of the innermost steel plate 20, and then the bonded cylindrical steel plates 20 are fitted onto the outside of the silo 10, so that several steel plates 20 can be installed on the outer wall of the silo 10 to support and protect the silo 10.

[0027] It should be noted that the structural adhesive 30 can effectively fix the silo 10 and the steel plate 20, as well as the two adjacent steel plates 20, to control the deformation of the silo and ensure that the silo will not deform drastically during the unloading of materials in sections.

[0028] This utility model also provides a cement raw material homogenization silo. The outer side of the silo 10 of the homogenization silo is provided with the constraint structure in the above embodiment. By using the above constraint structure to strengthen the structure at the corresponding positions of the section section of the homogenization silo, it is possible to avoid the formation of a reverse bending force on the surface of the homogenization silo during the unloading of materials in sections, which would cause uneven stress on the homogenization silo and thus prevent cracking of the outer wall of the silo 10.

[0029] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
