Abstract
Description
Technical Field
[0001] This utility model relates to the field of ash discharge valve technology, specifically a dust removal and ash discharge device. Background Technology
[0002] Existing double-layer flap ash discharge valves, without additional electronic components, generally achieve flap reset by spring pulling. However, springs are prone to aging, leading to seal failure, and have poor wear resistance, making them unsuitable for long-term use.
[0003] Publication No. CN221838904U discloses an ash discharge valve for dust removal equipment, which solves the problem that the impeller feeding space inside most ash discharge valves is limited, and the pushing impeller is prone to wear after long-term use, affecting the long-term stability of the ash discharge valve. It includes a spacer frame, a closed carrier plate, a collecting support cylinder, an ash discharge frame, a bearing side cover, and a closed side cover. The spacer frame has an installation groove A on its side. The closed carrier plate is fixedly installed on the side of the spacer frame. The collecting support cylinder is fixedly installed inside the mounting grooves A and B. The ash discharge frame has docking side frames fixedly installed on both sides. The bearing side cover is fixedly installed at one end of the ash discharge frame. A directional gear, in conjunction with a gear cylinder and a gear belt, drives the transmission shaft and transmission gear to rotate in opposite directions, causing the two sets of closed support plates to dock with the positioning support alternately. The ash discharge blades, in conjunction with the ash discharge frame and semi-ring support block, provide stable ash discharge and conveying. However, this patent still has the following problems in actual use:
[0004] In the intermittent closing process of the two flaps in the above-mentioned device, there is a situation where one flap is not fully reset before the other flap opens, which is not very practical. Some existing double-layer flap ash discharge valves use counterweights to achieve reset, but the counterweights are often installed as a single piece, which results in a fixed reset speed of the flaps. Since the reset speed of the flaps affects the dust flow rate, neither the above-mentioned device nor existing equipment can change the dust flow rate without increasing the opening speed of the flaps.
[0005] A dust removal and ash unloading device is proposed to solve the problems mentioned above. Utility Model Content
[0006] The purpose of this utility model is to provide a dust removal and ash discharge device to solve the problem mentioned in the background art that some existing double-layer flap ash discharge valves use counterweights to achieve reset, but the counterweights are often installed as a single unit, resulting in a fixed reset speed of the flap. Since the reset speed of the flap affects the dust flow rate, neither the above-mentioned device nor the existing equipment can change the dust flow rate without changing the flap opening speed.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a dust removal and ash unloading device, including an ash unloading valve;
[0008] The bottom of the ash discharge valve is provided with a layering assembly, which includes a first layering cylinder and a second layering cylinder fixedly connected at the top and bottom. The first layering cylinder is fixed to the bottom of the ash discharge valve. The top of both the first and second layering cylinders is fixedly connected to a vertical pipe. A support plate is provided below the vertical pipe. A rotating shaft is fixedly connected to one side of the support plate. The rotating shaft rotates through the first layering cylinder. A counterweight assembly is provided at one end of the rotating shaft. A connecting strip is fixedly connected to the other end of the rotating shaft. Rollers are rotatably mounted on the ends of the connecting strips through bearings. A lifting frame is fixedly connected to one side of the first layering cylinder. A motor is fixedly connected to the top surface of the lifting frame. An arc panel is fixedly connected to the output end of the motor. The curved surface of the arc panel rolls in contact with the outer edge of the roller.
[0009] The counterweight assembly includes a fixed sleeve that is welded to the other end of the rotating shaft. A connecting rod is fixedly connected to the outside of the fixed sleeve. A counterweight block is provided at the end of the fixed sleeve. Connecting rings are fixedly connected to both ends of the counterweight block. A connecting ring is also fixedly connected to the bottom end of the connecting rod. A bent hook plate and a step bar are symmetrically fixedly connected to the outside of the connecting ring.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This dust removal and ash unloading device, with its double-layer ash unloading valve, achieves continuous operation and low leakage rate through a double-layer cylinder alternating ash unloading design; it uses counterweights instead of springs, and precisely adjusts the reset speed by increasing or decreasing the number of counterweights and frictional resistance, thus extending service life and stability; its modular structure supports quick assembly and disassembly and flow step control, adapting to multiple working conditions and balancing high efficiency and durability. The specific details are as follows:
[0017] 1. The alternating ash discharge of the double-layered drums and dynamic sealing design significantly improves work efficiency and leak-proof performance. The motor drives the arc panel to rotate, and the linkage connecting strip and rotating shaft control the movement of the tray, enabling seamless switching of the upper and lower layered drums for ash discharge. This ensures that the layered drums that are not in operation during the ash discharge process are completely sealed. The use of counterweights to replace traditional springs, and the adjustment of the reset speed by increasing or decreasing the number of counterweights and the friction of the friction rubber pads, completely solves the problem of reset failure caused by spring corrosion. The modular design of the connecting ring and stepped strip structure supports quick installation and overlapping, achieving precise step-by-step control of dust flow to adapt to different working conditions.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-5 The present invention provides a technical solution: a dust removal and ash unloading device, including an ash unloading valve 1;
[0026] The bottom of the ash discharge valve 1 is provided with a layering component 2, which includes a first layering cylinder 201 and a second layering cylinder 202 fixedly connected vertically. The first layering cylinder 201 is fixed to the bottom of the ash discharge valve 1. The top of both the first layering cylinder 201 and the second layering cylinder 202 are fixedly connected to a vertical pipe 203. A support plate 205 is provided below the vertical pipe 203. A rotating shaft 204 is fixedly connected to one side of the support plate 205. The rotating shaft 204 rotates through the first layering cylinder 201. A counterweight component 3 is provided at one end of the rotating shaft 204, and the other end of the rotating shaft 204 is fixedly connected to... A connecting strip 207 is attached, and rollers 208 are rotatably mounted on the ends of the connecting strip 207 via bearings. A lifting frame 209 is fixedly connected to one side of the first layering cylinder 201, and a motor 210 is fixedly connected to the top surface of the lifting frame 209. An arc panel 211 is fixedly connected to the output end of the motor 210, and the curved surface of the arc panel 211 rolls in contact with the outer edge of the rollers 208. The bottom of the ash discharge valve 1 is fixed to the layering assembly 2 via a flange. The top of the first layering cylinder 201 is aligned with the outlet of the ash discharge valve 1, and vertical pipes 203 are provided on its top and the top of the second layering cylinder 202.
[0027] The counterweight assembly 3 includes a fixed sleeve 301 that is welded to the other end of the rotating shaft 204. A connecting rod 302 is fixedly connected to the outside of the fixed sleeve 301. A counterweight block 303 is provided at the end of the fixed sleeve 301. A connecting ring 304 is fixedly connected to both ends of the counterweight block 303. A connecting ring 304 is also fixedly connected to the bottom end of the connecting rod 302. A bent hook plate 305 and a step bar 306 are symmetrically fixedly connected to the outside of the connecting ring 304. The fixed sleeve 301 is welded to the end of the rotating shaft 204. The connecting ring 304 is fixed to the end of the connecting rod 302. The two ends of the counterweight block 303 are connected in series through the connecting ring 304. The bent hook plate 305 and the step bar 306 are symmetrically welded to the outside of the counterweight block 303. The guide slope 3061 and the extension plane 3062 are used to engage and lock with the bent hook plate 305 of the adjacent counterweight block 303.
[0028] A seepage-proof pad 206 is fixedly connected to the top surface of the support plate 205, and the seepage-proof pad 206 is attached to the bottom surface of the vertical pipe 203; the seepage-proof pad 206 is bonded to the top surface of the support plate 205, and when closed, it is attached to the bottom of the vertical pipe 203 for sealing.
[0029] The two vertical pipes 203 have different lengths, and the lower connecting strip 207 is fixedly installed at an angle upward, while the upper connecting strip 207 is fixedly installed at an angle downward. The two connecting strips 207 are installed at an angle of 30°-45° respectively, to ensure that the upper and lower support plates 205 move alternately when the arc panel 211 rotates, so as to realize the alternating ash discharge of the dual channels.
[0030] The lifting frame 209 is also fixedly connected to the outside of the second layered cylinder 202; the bottom of the lifting frame 209 is connected to the outer wall of the second layered cylinder 202 by bolts, and the top supports the motor 210. The triangular reinforcing rib design disperses the vibration load and prevents the cylinder from deforming.
[0031] The bent hook plate 305 and the step strip 306 installed on different connecting rings 304 are engaged and connected; the step strip 306 has a guide slope 3061 and an extension plane 3062 on the side that is in contact with the bent hook plate 305; the end face of the connecting ring 304 is fixedly connected to a friction rubber pad 307; the guide slope 3061 of the step strip 306 is at an angle of 15°-20° to the horizontal plane. When the bent hook plate 305 slides, the distance between the two connecting rings 304 is reduced by 2-3mm. The friction rubber pad 307 is deformed under pressure to increase friction and prevent loosening. When the counterweight 303 is stacked, the bent hook plate 305 slides into the extension plane 3062 along the guide slope 3061 of the step strip 306. The friction rubber pad 307 self-locks, and a single person can complete the assembly and disassembly.
[0032] Working principle: Before using this dust removal and ash unloading equipment, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5 As shown, the motor 210 is started first, causing the arc panel 211 to rotate and contact the roller 208. As the arc panel 211 rotates, the roller 208 rolls along the outer side of the arc panel 211, causing the connecting strip 207 to be rotated and lifted, thereby causing the rotating shaft 204 to drive the support plate 205 to rotate downward, thereby causing the seepage-proof pad 206 in the first layering cylinder 201 to leave the bottom of the vertical pipe 203. Then, the dust released by the ash discharge valve 1 enters the interior of the first layering cylinder 201 through the vertical pipe 203 and falls onto the seepage-proof pad 206 in the second layering cylinder 202.
[0033] After the arc panel 211 rotates and is lifted off the connecting strip 207, the counterweight assembly 3 will cause the rotating shaft 204 inside the first layered cylinder 201 to rotate and reset, and allow the support plate 205 to push the anti-seepage pad 206 to seal the vertical pipe 203 inside the first layered cylinder 201.
[0034] As the arc panel 211 continues to rotate, it will contact the roller 208 located below and push its corresponding connecting strip 207 to rotate, thereby causing the anti-seepage pad 206 in the second layered cylinder 202 to rotate downwards, causing the dust above it to fall. During this process, the ash discharge valve 1 on the first layered cylinder 201 and the second layered cylinder 202 are separated by the support plate 205 in the first layered cylinder 201. By adjusting the number of counterweights 303, the reset time of the rotating shaft 204 is changed, thereby controlling the duration of the support plate 205 moving away from the vertical pipe 203, and realizing the step-by-step adjustment of the dust flow rate.
[0035] Furthermore, by rotating the different connecting rings 304 after they are in contact with each other, the friction rubber pads 307, while in contact with each other, cause the bent hook plate 305 to slide along the guide slope 3061 and slide into the extension plane 3062, thereby enabling the counterweight block 303 to be quickly installed and stacked, indirectly controlling the speed at which the rotating shaft 204 rotates and resets due to tension.
[0036] The connecting ring 304 pulls the rotating shaft 204 through the connecting rod 302 and the fixed sleeve 301, so that the support plate 205 can automatically avoid the reduction of elasticity caused by the corrosion and aging of the spring when the traditional spring is pulled to reset, thereby eliminating the problem of reduced reset speed or affecting the reset time of the support plate 205.
[0037] By controlling the different tensions applied to the rotating shaft 204, its reset time is indirectly controlled, thereby controlling the duration for which the tray 205 moves away from the vertical pipe 203, ultimately achieving precise adjustment of the amount of dust passing through the vertical pipe 203.
[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
