Description

Technical Field

[0001] This utility model relates to the field of flue gas valve technology, and in particular to a modular assembly flue gas valve frame. Background Technology

[0002] A search revealed that patent number CN202223269702.9 discloses a novel flue gas duct slide valve frame profile, comprising channel steel, H-beams, and supporting flat steel and supporting angle steel bolted together between the channel steel and H-beams. A hydraulic cylinder is mounted on the bottom end of the channel steel via a first bolt. Ribs are provided on the side walls of both the channel steel and H-beams. A slide door is located inside the H-beam. A blind ash collection trough is fixed to the bottom end of the H-beam via bolts. By setting supporting flat steel and supporting angle steel between the channel steel and H-beams, and by providing ribs on their side walls, the flue gas duct slide valve frame profile increases the overall bending resistance of the slide valve. This frame profile prevents serious problems such as damage, bending, and deformation of the frame during the opening and closing of the slide valve. The aforementioned patent increases the overall rigidity by adding channel steel and H-steel, thereby improving the bending strength of the frame. However, in actual use, it has been found that the aforementioned patent is not easy to disassemble, as it does not have a modular design, which makes disassembly difficult in the early or later stages. At the same time, a large amount of dust, such as coal dust and blast furnace ash, can easily enter the frame, causing the valves to become stuck when opening and closing.

[0003] Therefore, we propose a modular, assembled flue gas valve frame. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] This utility model provides a modular, assembled flue gas valve frame that solves the problem of difficult frame disassembly. The specific solution is as follows: A modular, assembled flue gas valve frame includes a frame body, a top plate fixedly connected to the top of the frame body, a valve movably connected to the middle of the frame body, and several sets of reinforcing ribs evenly arranged on the valve; multiple reinforcing plates are movably connected to both sides of the frame body, with two reinforcing plates forming a group, and a group of reinforcing plates symmetrically inserted at the edge of the frame body; a retaining plate is fixedly connected to the tail end of the reinforcing plate, and an insertion hole is opened on the retaining plate; a cleaning structure is movably connected to the middle of the reinforcing plate, and the cleaning structure includes a scraper, the end of which contacts the inner wall of the flue.

[0006] As a preferred technical solution of this utility model, the dust removal structure further includes a fixing plate, which is fixedly installed between two reinforcing plates. A vertical plate is fixedly connected to the bottom of one end of the fixing plate, and an electric guide rail is fixedly connected to the middle of the vertical plate.

[0007] As a preferred embodiment of this utility model, the middle part of the electric guide rail is connected to a movable block, the end of the movable block is fixedly connected to a miniature electric cylinder, the output end of the miniature electric cylinder is connected to the tail of the scraper, and the miniature electric cylinder drives the scraper to move radially.

[0008] As a preferred technical solution of this utility model, slots are opened on both sides of the edge of the frame body, and multiple sets of pin rods are connected to the top of the frame body. The positions of the slots correspond to the positions of the card plates, and the card plates are embedded in the slots.

[0009] As a preferred technical solution of this utility model, the pin rod is embedded in the frame body and interpenetrates with the insertion hole on the top of the card plate, and a number of curved anti-slip textures are provided on the surface of the pin rod.

[0010] As a preferred embodiment of this utility model, a cylinder is fixedly connected to the top of the top plate, and the output end of the cylinder passes through the top plate and the frame body and extends to the inner side of the frame body.

[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0016] See Figures 1-4 This utility model provides a modular assembled flue gas slide valve frame, including a frame body 1, a top plate 2 fixedly connected to the top of the frame body 1, and a valve 5 movably connected to the middle of the frame body 1. Several sets of reinforcing ribs 6 are evenly arranged on the valve 5. The reinforcing ribs 6, through longitudinal arrangement, disperse the concentrated stress on the valve body surface to the entire structure, reducing the local stress peak. The flue gas slide valve needs to withstand extreme conditions such as high temperature, negative pressure, and flue gas impact. The reinforcing ribs 6 can improve the pressure resistance and impact resistance without significantly increasing the wall thickness of the body. The reinforcing ribs 6 increase the natural frequency of the structure, avoid the resonance frequency range of the equipment operation, and reduce the vibration amplitude through rigid reinforcement.

[0017] Multiple reinforcing plates 7 are movably connected to both sides of the frame body 1. Two reinforcing plates 7 form a group, and a group of reinforcing plates 7 are symmetrically inserted into the edge of the frame body 1. The tail end of the reinforcing plate 7 is fixedly connected to a clamping plate 11, and the clamping plate 11 has an insertion hole. The middle part of the reinforcing plate 7 is movably connected to a dust removal structure, which includes a scraper 10. The end of the scraper 10 contacts the inner wall of the flue.

[0018] The dust removal structure also includes a fixing plate 8, which is fixedly installed between two reinforcing plates 7. One end of the fixing plate 8 is fixedly connected to a vertical plate 14, and the middle of the vertical plate 14 is fixedly connected to an electric guide rail 12.

[0019] The electric guide rail 12 is connected to a movable block 15 in the middle. A miniature electric cylinder 13 is fixedly connected to the end of the movable block 15. The output end of the miniature electric cylinder 13 is connected to the tail of the scraper 10, and the miniature electric cylinder 13 drives the scraper 10 to move radially. The scraper 10 removes residual smoke and dust, preventing long-term adhesion and the formation of a corrosive medium layer. It also reduces the impact and wear of smoke and dust particles on the inner wall, reducing smoke and dust wear around the slide valve frame and sealing seat by 90%, thus extending the service life of the frame body 1. Regular cleaning of the scraper 10 maintains a stable flue cross-sectional area, reduces airflow eddies and local resistance, and optimizes the flue gas flow field. Slots 9 are provided on both sides of the edge of the frame body 1. Multiple sets of pins 16 are connected to the top of the frame body 1. The positions of the slots 9 correspond to the positions of the card plates 11, and the card plates 11 are embedded in the slots 9.

[0020] The pin 16 is embedded in the frame body 1 and interlocks with the insertion hole on the top of the card plate 11. Several curved anti-slip textures 17 are provided on the surface of the pin 16. The card plate 11 and the frame body 1 are fixed by the pin 16, which improves the connection stability between the two.

[0021] The top of the top plate 2 is fixedly connected to the cylinder 3. The output end of the cylinder 3 passes through the top plate 2 and the frame body 1 and extends to the inside of the frame body 1.

[0022] The output end of cylinder 3 is connected to push rod 4. Push rod 4 is located in the middle of frame body 1, and the bottom end of push rod 4 is connected to the top end of valve 5. By setting cylinder 3, valve 5 can be driven to move up and down inside frame body 1, thereby completing the opening and closing of valve 5.

[0023] Slots 9 are provided on both sides of the frame body 1, and a reinforcing plate 7 is added. The reinforcing plate 7 can be directly embedded into the slot 9 through the clip 11. The two are spliced ​​and fixed by the pin rod 16, which improves the firmness of the frame body 1 inside the flue and greatly reduces the time for disassembly and installation. By adding a vertically movable scraper 10 in the middle of the reinforcing plate 7, the tail of the scraper 10 is connected to the micro electric cylinder 13. The distance between the scraper 10 and the inner wall of the flue can be controlled and adjusted. As the scraper 10 moves up and down, the dust on the inner wall of the flue is scraped off, improving the cleanliness of the inner wall of the flue and preventing dust from entering the gaps inside the frame body 1, which would make it difficult to open and close the valve 5.
