Description

Technical Field

[0001] This utility model relates to the field of thermal power generation technology, and in particular to a support device and a dust removal device. Background Technology

[0002] Currently, in thermal power plants, the flue gas velocity in the pre-dust collector flue is relatively high, and since it has not yet undergone dust removal treatment, the dust content is high. Dust particles passing through the pre-dust collector flue cause significant scouring and abrasion to the flue and its internal components. Internal support rods are one such component installed within the flue to enhance its structural stability. In existing technology, angle steel is typically installed on the windward side of the internal support rod in an attempt to protect it. However, due to the high dust concentration and high particle kinetic energy in the pre-dust collector flue, the angle steel frequently comes into rigid contact with the internal support rod under the scouring of high-intensity dust. This rigid contact makes the internal support rod susceptible to damage, and the angle steel is easily worn through by the dust. Once the angle steel is worn through, the dust directly scouring the internal support rod, resulting in limited protective effect and difficulty in effectively extending the service life of the internal support rod. Utility Model Content

[0003] The purpose of this utility model is to provide a support device and a dust removal device to solve the technical problem that angle steel will frequently come into rigid contact with the inner support rod under the scouring of high-intensity dust, and will be easily worn through by the dust, resulting in poor durability and short service life of the inner support rod.

[0023] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0024] In the description of this utility model, it should be understood that the terms "top", "bottom", "inner", "outer", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] like Figures 1 to 3 As shown, a support device of this utility model includes an inner support rod, a wear-resistant sleeve, and a filling layer. The inner support rod is vertically arranged, with its top end connected to the top surface of the flue and its bottom end connected to the bottom surface of the flue. The wear-resistant sleeve is fitted over the outer side of the inner support rod, forming a first gap between the wear-resistant sleeve and the inner support rod. The filling layer is filled within the first gap, and the wear-resistant sleeve and the filling layer are connected to the inner support rod. The wear-resistant sleeve is made of a wear-resistant material, and the filling layer is made of a soft material.

[0027] In the above technical solution, the top and bottom ends of the inner support rod are respectively connected to the top and bottom surfaces of the flue of the dust collector body to enhance the structural stability of the flue. Furthermore, wear-resistant sleeves are spaced and fitted onto the outside of the inner support rod, providing a first layer of protection. Further, a first gap is formed between the wear-resistant sleeve and the inner support rod, preventing the wear-resistant sleeve from rigidly contacting the inner support rod when it is being scoured, swaying horizontally, or undergoing thermal expansion, thus avoiding collisions and damage. Furthermore, a soft filling layer within the first gap effectively absorbs vibrations generated by the wear-resistant sleeve, and when parts of the wear-resistant sleeve are worn through, the filling layer provides a second layer of protection for the inner support rod. In summary, this utility model's support device effectively protects the inner support rod, greatly improving its durability and increasing its service life.

[0028] The wear-resistant sleeve and the filler layer are detachably connected to the inner support rod for easy installation and replacement. Specifically, the wear-resistant sleeve and the filler layer can be connected to the inner support rod by fasteners, or the wear-resistant sleeve can be connected to the filler layer by adhesive, and the filler layer can then be connected to the inner support rod.

[0029] In addition, the inner struts are high-strength and high-rigidity components to enhance the structural stability of the flue, the wear-resistant sleeves are high-wear-resistant components to withstand the erosion of dust, and the filling layer is a low-hardness component to absorb vibration and impact.

[0030] Furthermore, it also includes a shielding member and a plurality of wear-resistant sleeves, the plurality of wear-resistant sleeves being spaced apart in the vertical direction, with a second gap formed between two adjacent wear-resistant sleeves, the shielding member corresponding to each of the second gaps and connected to the wear-resistant sleeves forming the corresponding second gaps, the shielding member including a connecting part and a shielding part connected together, the connecting part being sleeved on the outside of the wear-resistant sleeve and connected to the outer surface of the wear-resistant sleeve, one end of the shielding part being connected to the outer surface of the connecting part, and the other end extending in the vertical direction, the shielding part shielding the second gap in the horizontal direction; wherein, the shielding member is made of wear-resistant material.

[0031] Multiple wear-resistant sleeves are spaced apart on the inner support rod to protect the inner support rod in sections, so as to facilitate the installation and removal of the wear-resistant sleeves on the inner support rod. It also allows multiple standard length wear-resistant sleeves to be adapted to be installed on inner support rods of different lengths. In addition, the second gap can prevent the wear-resistant sleeves from making rigid contact due to thermal expansion, and prevent the wear-resistant sleeves from damaging each other. The shielding part is used to shield the second gap to prevent dust from directly washing over the inner support rod through the second gap.

[0032] Furthermore, the wear-resistant sleeve has at most one shielding member, and the extension direction of the end of each shielding member away from the connecting part is the same; wherein, by unifying the extension direction, the disorderly disturbance of flue gas between the shielding members can be reduced, so as to form a regular airflow channel, thereby reducing the impact frequency of dust particles on the shielding members and the sleeve, and also avoiding assembly errors caused by chaotic direction, thereby improving the assembly efficiency of the device.

[0033] Furthermore, the shielding member is connected to the wear-resistant sleeve located above, which forms the second gap, and the shielding portion extends downward at one end away from the connecting portion; wherein, the downwardly extending shielding portion can guide dust particles accumulated on the surface of the shielding member to slide down the shielding portion to the bottom of the flue, preventing dust from accumulating in the second gap and thus contacting the inner support rod.

[0034] Furthermore, the top of the shielding part is higher than the second gap, and its bottom is lower than the second gap, to ensure that the shielding part can fully cover the second gap and prevent dust from entering the second gap.

[0035] Furthermore, the width of the second gap in the vertical direction is 8mm to 12mm, and the distance between the end of the connecting part away from the wear-resistant sleeve and the wear-resistant sleeve is 8mm to 12mm. The width of the L-shaped notch formed by the gap between the connecting part and the outer side of the wear-resistant sleeve and the second gap is 8mm to 12mm, so as to prevent the wear-resistant sleeve from rigidly contacting the adjacent wear-resistant sleeve and the adjacent shielding member due to thermal expansion. In addition, the thickness of the shielding member is 6mm to 8mm to ensure that the shielding member has sufficient protective thickness, avoiding insufficient thickness leading to rapid penetration, or excessive thickness increasing unnecessary weight and cost.

[0036] Furthermore, the outer diameter of the inner support rod is 60mm to 70mm, and the thickness of the inner support rod is 4mm to 6mm, so that the inner support rod has sufficient strength and rigidity. The radial width of the first gap is 8mm to 12mm, so as to provide sufficient deformation space for the filling layer and ensure that it can still effectively fill the gap after the sleeve is worn. The thickness of the wear-resistant sleeve is 5mm to 10mm, so as to ensure that the wear-resistant sleeve has sufficient protective thickness and avoid insufficient thickness leading to rapid penetration, or excessive thickness increasing unnecessary weight and cost. The length of the wear-resistant sleeve in the vertical direction is 300mm to 500mm, so as to balance the wear-resistant coverage area and the weight of a single sleeve section, and facilitate manual disassembly and assembly.

[0037] Furthermore, a connecting hole is provided, which extends horizontally through the inner support rod, the wear-resistant sleeve, and the filling layer; a connecting pin is also included, which passes through the connecting hole to fix the inner support rod, the wear-resistant sleeve, and the filling layer; wherein, the connecting pin is mechanically locked to rigidly fix the three into a whole, ensuring that the wear-resistant sleeve will not undergo circumferential or axial displacement under high temperature and high dust impact environment. In addition, the part of the connecting pin exposed outside the wear-resistant sleeve (the end of the pin head and pin shank away from the pin head) and related fasteners (such as nuts and washers) should be made of wear-resistant material.

[0038] Furthermore, the wear-resistant material can be metal, ceramic, or polymer material. The metal can be alloy steel, high manganese steel, or cast iron. The ceramic can be alumina or silicon carbide. The plastic can be polytetrafluoroethylene to meet the wear-resistant requirements of the wear-resistant sleeve and shield. The soft material is plant fiber, rubber, or glass wool. In addition, the soft layer can be composed of hemp rope and wrapped around the outside of the inner support rod.

[0039] This embodiment also relates to a dust removal device, including a dust collector body and the aforementioned support device. The dust collector body is provided with a front flue, and the support device is provided in the front flue. The top end of the inner support rod is connected to the top surface of the flue, and the bottom end of the inner support rod is connected to the bottom surface of the flue.

[0040] Furthermore, fixed setting and fixed connection refer to the fixed relative positional relationship of two components, including but not limited to fixing by connectors, fixing by welding, fixing by adhesive, fixing by integral molding, and fixing by snap-fit ​​connection.

[0041] Furthermore, detachable connection and detachable setting refer to the ability of two components to be repeatedly assembled and disassembled without damage or severe deformation, including but not limited to fixing by connectors or fixing by snap-fit ​​connections.

[0042] Furthermore, the connectors include, but are not limited to, fasteners, straps, ropes, pneumatic connectors, hydraulic connectors, flanges, Velcro, and buttons.

[0043] In summary, the present invention provides a support device and a dust removal device, the technical effects of which are as follows:

[0044] In this utility model's support device, the top and bottom ends of the inner support rod are respectively connected to the top and bottom surfaces of the flue of the dust collector body to enhance the structural stability of the flue. Furthermore, wear-resistant sleeves are spaced and fitted onto the outside of the inner support rod, providing a first layer of protection. Additionally, a first gap is formed between the wear-resistant sleeve and the inner support rod, preventing the wear-resistant sleeve from rigidly contacting the inner support rod when it is being washed, swaying horizontally, or undergoing thermal expansion, thus avoiding collisions and damage. Furthermore, a soft filling layer within the first gap effectively absorbs vibrations generated by the wear-resistant sleeve, and when parts of the wear-resistant sleeve are worn through, the filling layer provides a second layer of protection for the inner support rod. In summary, this utility model's support device effectively protects the inner support rod, significantly improving its durability and increasing its service life.
