Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve technology, specifically to a slurry conveying valve with a scraper mechanism. Background Technology
[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems, and their types and specifications are quite numerous.
[0003] For example, patent number CN 222633840 U discloses a valve that addresses the problem of poor stability in existing valves. When external vibrations are transmitted to the valve, it shakes, causing slight wobbling of the valve mechanism and leading to loosening of the connection between the valve mechanism and the main body, resulting in water leakage. The proposed solution includes a valve mechanism housed inside the valve cover for controlling water flow in the connecting pipe, and a stabilizing mechanism housed on the outer wall of the valve cover for stable positioning of the valve mechanism. In use, this invention can limit and fix the handwheel, improving its stability and preventing shaking caused by external vibrations. This avoids slight wobbling of the valve mechanism and loosening of the connection between the valve mechanism and the connecting pipe, thus preventing water leakage.
[0004] For example, patent number CN 222963443 U discloses a valve. The valve includes: a valve stem, a valve stroke display, a valve stroke measuring plate, a valve stroke measuring device, and a human-machine interface terminal. The valve stroke measuring device is disposed inside the valve and includes a base, a laser displacement sensor, a first communication module, and a microprocessor. The laser displacement sensor is disposed on the base, and the first communication module and microprocessor are disposed inside the base. The human-machine interface terminal is provided with a second communication module and an operating interface. The valve stroke measuring device is located below the valve stroke measuring plate. Data measured by the laser displacement sensor is processed by the microprocessor and sent to the first communication module, and then transmitted to the human-machine interface terminal, realizing long-distance data transmission. This utility model facilitates the collection of valve stroke data and realizes automated control, with high measurement efficiency and accuracy.
[0005] The aforementioned patent addresses the issue that during long-term slurry transport, the slurry often contains a large number of solid particles. These particles easily adhere to the inner wall and sealing surface of the valve during opening and closing. Over time, these accumulated particles reduce the valve's sealing performance, leading to leakage. This not only wastes slurry but may also pollute the surrounding environment. Furthermore, particle accumulation increases the valve's operating resistance, making opening and closing difficult and affecting the overall operating efficiency of the transport system. Utility Model Content
[0006] (a) Technical problems to be solved
[0007] To address the shortcomings of existing technologies, this utility model provides a slurry conveying valve with a scraper mechanism. This solves the problem that when existing slurry conveying valves transport slurries containing a large number of solid particles for a long time, the particles easily adhere to the inner wall and sealing surface of the valve, leading to a decrease in sealing performance, leakage, slurry waste, and environmental pollution. At the same time, particle accumulation increases the valve's operating resistance and affects the normal operating efficiency of the conveying system.
[0008] (II) Technical Solution
[0009] To achieve the above objectives, this utility model provides the following technical solution: a slurry conveying valve with a scraper mechanism, comprising a valve body, an opening and closing gate inside the valve body, a housing inside the valve body, a main gate inside the housing, a secondary gate to the right of the main gate, a rotating main shaft between the main gate and the secondary gate, rotating connecting shafts at both ends of the rotating main shaft, sealing sleeves on the rotating connecting shafts, the sealing sleeves being respectively located in the middle of the main gate and the secondary gate, a scraper connecting frame at the other end of the rotating connecting shaft, a fixing screw fixing the scraper connecting frame to the rotating connecting shaft, and two scrapers connected to the scraper connecting frame.
[0010] Preferably, a driven pulley is provided in the middle of the rotating main shaft, the driven pulley is connected to a transmission belt, the other end of the transmission belt is connected to a driving pulley, the middle of the driving pulley is connected to a pulley support shaft, and the two ends of the pulley support shaft are respectively connected to the main gate and the auxiliary gate.
[0011] Preferably, a driven bevel gear is provided on the left side of the pulley support shaft, and a driving bevel gear is connected to the lower side of the driven bevel gear. The driving bevel gear is connected to the upper end of the gear support shaft, and the gear support shaft is connected to the main gate.
[0012] Preferably, a power shaft is provided below the housing, the upper end of the power shaft is connected to the lower end of the gear support shaft, and the lower end of the power shaft is connected to a motor connection port.
[0013] Preferably, the upper end of the housing is provided with a gate rotation shaft, the lower end of the gate rotation shaft is connected to the upper end of the main gate, and the upper end of the gate rotation shaft is connected with a rotation handle.
[0014] (III) Beneficial Effects
[0015] This utility model provides a slurry conveying valve with a scraper mechanism. It has the following advantages:
[0016] This slurry conveying valve with a scraper mechanism effectively solves many problems existing in current slurry conveying valves through its unique structural design. It avoids particle accumulation, thus maintaining excellent sealing performance and significantly reducing leakage. This not only reduces slurry waste and lowers production costs but also prevents environmental pollution caused by slurry leaks, meeting environmental protection requirements.
[0017] Because the scraper continuously cleans the particle buildup inside the valve, it effectively reduces the valve's operating resistance. Operators can more easily and smoothly control the opening and closing of the main and auxiliary gates by rotating the handle through the gate's rotating shaft, reducing manpower consumption and operational difficulty. Simultaneously, the smooth operation of the valves ensures the stable operation of the entire slurry conveying system, improves conveying efficiency, and avoids system failures and downtime caused by difficult valve operation, providing strong support for the continuity and stability of production.
[0018] This device is based on an improvement of existing equipment, so the improvement cost is relatively low and it will not cause a large amount of existing equipment to be discarded. It ensures the processing effect while reducing the investment in improvement costs, making it suitable for large-scale production. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0024] Please see Figure 1-3 This utility model provides a technical solution: a slurry conveying valve with a scraper mechanism, including a valve body 1, an opening and closing gate 2 inside the valve body 1, a housing 11 on the valve body 1, a power shaft 14 below the housing 11, the upper end of the power shaft 14 being connected to the lower end of a gear support shaft 215, the lower end of the power shaft 14 being connected to a motor connection port 15, a gate rotation shaft 12 on the upper end of the housing 11, and the lower end of the gate rotation shaft 12 being connected to... The upper ends of the main gate 201 are interconnected. The upper end of the gate rotation shaft 12 is connected to a rotation handle 13. The main gate 201 is installed inside the housing 11. A secondary gate 202 is installed to the right of the main gate 201. A rotating main shaft 203 is installed between the main gate 201 and the secondary gate 202. A driven pulley 209 is installed in the middle of the rotating main shaft 203. The driven pulley 209 is connected to a transmission belt 210. The other end of the transmission belt 210 is connected to an active... A pulley 211 is provided, with its central portion connected to a pulley support shaft 212. A driven bevel gear 213 is disposed on the left side of the pulley support shaft 212, and a driving bevel gear 214 is connected to the lower side of the driven bevel gear 213. The driving bevel gear 214 is connected to the upper end of a gear support shaft 215, which is interconnected with the main gate 201. Both ends of the pulley support shaft 212 are respectively connected to the main gate 201 and the auxiliary gate 202. The rotating main shaft 203 is provided with rotating connecting shafts 204 at both ends. The rotating connecting shaft 204 is provided with sealing sleeves 205. The sealing sleeves 205 are respectively provided in the middle of the main gate 201 and the auxiliary gate 202. The other end of the rotating connecting shaft 204 is provided with a scraper connecting frame 206. The scraper connecting frame 206 and the rotating connecting shaft 204 are fixed with fixing screws 207. The scraper connecting frame 206 is connected to two scrapers 208.
[0025] During operation, when slurry residue adheres to the main gate 201 and auxiliary gate 202, the operator can connect the motor through the motor connection port 15, and the motor drives the power shaft 14 to rotate. The rotation of the power shaft 14 is transmitted to the gear support shaft 215, causing the driving bevel gear 214 connected to the upper end of the gear support shaft 215 to start rotating. The driving bevel gear 214 drives the driven bevel gear 213 connected to it to rotate, and the driven bevel gear 213 drives the pulley support shaft 212 to rotate, and the driving pulley 211 on the pulley support shaft 212 rotates accordingly. The driving pulley 211 drives the driven pulley 209 to rotate through the transmission belt 210, and the driven pulley 209 drives the rotating main shaft 203 to rotate. The rotating connecting shafts 204 at both ends of the rotating main shaft 203 also rotate. Since the rotating connecting shaft 204 is connected to the scraper 208 through the scraper connecting bracket 206 and the fixing screw 207, the scraper 208 will rotate with the rotation of the rotating connecting shaft 204. The rotating scraper 208 scrapes off the slurry residue adhering to the main gate 201 and the auxiliary gate 202. After cleaning, the operator manually operates the rotating handle 13, which drives the main gate 201 to rotate through the gate rotation shaft 12, thereby opening and closing the valve.
[0026] In summary, this slurry conveying valve with a scraper mechanism, through its unique structural design, effectively solves many problems existing in current slurry conveying valves, preventing particle accumulation and thus maintaining good sealing performance, significantly reducing leakage. This not only reduces slurry waste and lowers production costs but also avoids environmental pollution caused by slurry leakage, meeting environmental protection requirements.
