Description

A wear-resistant slurry valve Technical Field

[0001] This utility model relates to the field of slurry valve technology, specifically to an anti-wear slurry valve. Background Technology

[0002] A slurry valve is a valve plate product specifically designed for conveying solid-liquid mixtures such as mortar and mineral slurry. Slurry valves control the slurry flow rate by adjusting the flow cross-section. Typical slurry valves employ a ball valve or gate valve structure, increasing or decreasing the flow channel by raising or lowering a ball or valve plate, thereby achieving precise regulation.

[0003] Mineral slurry typically contains a large number of solid particles, which can cause strong impact and wear on the internal structure of the slurry valve during transportation.

[0004] Large particles in existing slurry cannot be broken up in time. When flowing through the valve pipe, they directly impact the inner wall of the valve pipe and other key components, accelerating the wear of the components. This leads to a decrease in valve sealing performance, a shortened service life, and even serious problems such as leakage, which in turn affects the normal transportation of slurry and increases production and maintenance costs. Therefore, an anti-wear slurry valve is proposed. Summary of the Invention

[0017] (III) Beneficial Effects

[0018] This utility model provides an anti-wear slurry valve. It has the following beneficial effects:

[0019] (I) This wear-resistant slurry valve has a crushing mechanism that uses a motor to drive a crushing rod to rotate, effectively crushing large slurry particles that fall onto the receiving plate after entering the crushing box. This reduces wear on the internal structure of the valve pipe, facilitating slurry transport. Simultaneously, when the motor is working, it drives a rotating rod via a pulley, causing the buffer sleeve and telescopic plate to rotate. Under centrifugal force, the telescopic plate expands and fits against the inner side of the receiving frame, allowing the slurry to fall onto the buffer sleeve first, buffering the impact force when it falls, avoiding direct impact on the receiving frame, extending the service life of the receiving frame, and further improving the wear resistance of the entire slurry valve.

[0020] (II) The wear-resistant slurry valve control mechanism drives the valve plate to rotate by rotating the rotating rod, changing the relative position between the valve plate and the inner wall of the valve pipe, thereby achieving precise adjustment or on / off control of the slurry flow rate, meeting the needs of flexible adjustment of slurry delivery in actual production. The wear-resistant sleeve slidingly fitted on the outer wall of the valve plate can reduce the wear between the valve plate and the slurry. When replacing the wear-resistant sleeve, it is only necessary to remove the mounting cover to take it out from the valve pipe for replacement. The operation is simple, which not only improves the service life of the valve plate, but also reduces maintenance costs and improves the economy and practicality of the slurry valve.

[0031] The crushing mechanism 3 includes a crushing section and a buffer section;

[0032] The crushing section includes a crushing box 31 and a crushing rod 37, and the buffer section includes two buffer sleeves 312 and two telescopic plates 313.

[0033] A connecting pipe 35 is fixedly installed through the outer wall of the crushing box 31, extending to the inner side of the crushing box 31. The connecting pipe 35 is connected to the valve pipe 1 by multiple bolts. A feed pipe 32 is fixedly installed through the outer wall of the crushing box 31, extending to the inner side of the crushing box 31. A receiving plate 36 is fixedly installed on the inner side of the crushing box 31. A mounting frame 38 is fixedly installed on the outer wall of the receiving plate 36. The inner side of the mounting frame 38 is rotatably connected to the outer wall of the crushing rod 37 through a bearing seat. A receiving frame 39 is fixedly installed on the inner side of the crushing box 31. The receiving frame 39 is located below the crushing rod 37. The side of the receiving frame 39 near the connecting pipe 35 extends to the inner side of the connecting pipe 35. A mounting bracket 33 is fixedly installed on the outer wall of the crushing box 31. A motor 34 is fixedly installed on the inner side of the mounting bracket 33. The output end of the motor 34 extends through the outer wall of the crushing box 31 and the outer wall of the mounting frame 38 to the inner side of the mounting frame 38. The outer wall of the rod 37 is fixedly connected. The inner side of the receiving frame 39 is rotatably provided with a rotating rod 310 through a bearing seat. The outer wall of the rotating rod 310 is fixedly connected to the outer walls of two buffer sleeves 312. Two telescopic plates 313 are slidably provided on the inner sides of the two buffer sleeves 312 respectively. The outer walls of the two telescopic plates 313 are slidably connected to the inner side of the receiving frame 39. Two limiting grooves are opened on the outer walls of the two buffer sleeves 312 respectively. Two limiting plates 314 are slidably provided on the inner walls of the two limiting grooves respectively. The side of the two limiting plates 314 near the two telescopic plates 313 is fixedly connected to the outer walls of the two telescopic plates 313 respectively. The outer wall of the rotating rod 310 passes through the inner side of the receiving frame 39 and the inner side of the crushing box 31 in sequence and extends to the outside of the crushing box 31. Two pulleys 311 are fixedly sleeved on the outer wall of the rotating rod 310 and the outer wall of the output end of the motor 34 respectively. The two pulleys 311 are driven by a belt.

[0034] The control mechanism 2 includes two valve plates 25. A fixed frame 23 is fixedly installed through the outer wall of the valve pipe 1 and extends to the inner side of the valve pipe 1. A rotating rod 21 is provided on the inner side of the fixed frame 23. The bottom surface of the rotating rod 21 extends to the inner side of the valve pipe 1. The outer wall of the rotating rod 21 is fixedly connected to the outer wall of the two valve plates 25. Two wear-resistant sleeves 26 are slidably fitted on the outer wall of the two valve plates 25 respectively. The two wear-resistant sleeves 26 are connected to the outer wall of the two valve plates 25 by two bolts. An installation cover 22 is fitted on the outer wall of the rotating rod 21. The installation cover 22 is connected to the top surface of the fixed frame 23 by three bolts. A baffle 24 is fitted on the outer wall of the rotating rod 21. The outer wall of the baffle 24 is slidably connected to the inner side of the fixed frame 23.

[0035] In use, the slurry enters the crushing box 31 through the feed pipe 32 and falls onto the receiving plate 36. At this time, the motor 34, which is fixedly connected to the crushing rod 37, is started to drive the crushing rod 37 to rotate and crush the large particles in the slurry. The crushed slurry falls into the receiving frame 39. Because the side of the receiving frame 39 near the connecting pipe 35 extends to the inside of the connecting pipe 35, the slurry can enter the connecting pipe 35 through the receiving frame 39 and flow into the valve pipe 1.

[0036] Meanwhile, when the motor 34 is working, it drives the rotating rod 310 to rotate through two pulleys 311 that are respectively fixed on the outer wall of the rotating rod 310 and the output end of the motor 34. When the rotating rod 310 rotates, it can drive the two buffer sleeves 312 and the two telescopic plates 313 to rotate. When the two buffer sleeves 312 and the two telescopic plates 313 rotate, the centrifugal force can cause the two telescopic plates 313 to expand outward. When the two telescopic plates 313 expand outward, they can fit against the inner side of the receiving frame 39, so that the slurry can fall on the buffer sleeves 312 first, and can buffer the slurry when it falls, avoiding impact on the receiving frame 39.

[0037] When it is necessary to control the flow rate or on / off state of the slurry in the valve pipe 1, the rotating rod 21, which is set on the inner side of the fixed frame 23 and whose bottom surface extends to the inner side of the valve pipe 1, is rotated. The rotating rod 21 drives the two valve plates 25, which are fixedly connected to its outer wall, to rotate, changing the relative position of the valve plates 25 and the inner wall of the valve pipe 1, thereby realizing the adjustment or on / off control of the slurry flow rate. The wear-resistant sleeve 26, which is slidably fitted on the outer wall of the valve plate 25, can reduce the wear between the valve plate 25 and the slurry, and improve the service life of the valve plate 25. The wear-resistant sleeve 26 can be replaced. When replacing, simply remove the mounting cover 22 from the top of the fixed frame 23. After removal, the two wear-resistant sleeves 26 can be taken out from the valve pipe 1 and replaced. After replacement, simply place them back inside the valve pipe 1, and then fix the mounting cover 22 to fix the rotating rod 21, the two valve plates 25 and the two wear-resistant sleeves 26.
