Description

Technical Field

[0001] This utility model relates to the field of slag discharge valve technology, specifically to a simple, lightweight, and temperature-resistant manual slag discharge valve device. Background Technology

[0002] Slag removal from valve bodies is a crucial step in ensuring the normal operation of valves and the stability of the system in industrial processes. In various industrial production processes, after long-term use, valves gradually accumulate impurities, particles, sediments, and other slag inside. If this slag is not cleaned in time, it will cause many problems. How to avoid slag leakage and how to improve valve plate stability and smooth slag removal are urgent problems to be solved.

[0003] CN217684968U discloses a slag discharge device for a boiler slag cooler, comprising a vertical slag discharge pipe and an inclined slag discharge pipe connected to the bottom of the vertical slag discharge pipe, the inclined slag discharge pipe and the vertical slag discharge pipe being an integral structure. A base plate is fixed to the bottom end of the inclined slag discharge pipe, and an opening with the same inner diameter as the inclined slag discharge pipe is opened at the overlapping position of the base plate and the inclined slag discharge pipe. In this utility model, a vertical slag discharge pipe and an inclined slag discharge pipe are provided, the inclined slag discharge pipe and the vertical slag discharge pipe being an integral structure, and a base plate is fixed to the bottom end of the inclined slag discharge pipe. An opening is opened at the overlapping position of the base plate and the inclined slag discharge pipe. A rotatable cover is provided on the side of the base plate away from the inclined slag discharge pipe, the cover can block the opening, and a rotation drive structure connected to the cover is provided on the side of the base plate away from the cover. When slag discharge is required, the rotation drive structure drives the cover to rotate, so that the cover no longer blocks the opening, and slag discharge can begin. Manual slag discharge is not required, making it safer and more reliable.

[0004] The above-mentioned slag discharge device for boiler slag cooler has the following problems: the cover and the bottom plate are sealed by direct metal contact, which is prone to deformation under long-term impact from high-temperature ash and slag, leading to seal failure or rotation jamming; at the same time, this design relies on the vibration of the slag-inserting rod driven by a motor to clear the blockage, and the spring is prone to fatigue and deformation. In addition, the additional power source required for the slag-inserting rod also increases production and maintenance costs. Utility Model Content

[0005] This invention proposes a simple, lightweight, and temperature-resistant manual slag discharge valve device, which solves the problems of insufficient high-temperature resistance and increased production and maintenance costs due to the need for additional power sources for vibration and unblocking in the prior art.

[0006] The technical solution of this utility model is as follows: A simple, lightweight, and temperature-resistant manual slag discharge valve device includes a valve body assembly, which includes a valve body body and a refractory castable fixedly connected to the inner side of the valve body body. An annular groove is formed on the inner side of the refractory castable. Manual opening and closing components are provided on the inner and outer sides of the valve body assembly. The manual opening and closing components include a valve plate that can rotate and lock at the annular groove. A refractory and temperature-resistant material layer is distributed on the outer layer of the valve plate. A slag vibrating component is provided on the inner side of the refractory castable and can rotate and contact the valve plate and vibrate vertically.

[0007] Preferably, the manual opening and closing assembly further includes a support frame, which is symmetrically and fixedly connected to the outside of the valve body. The manual opening and closing assembly also includes a rotating rod, which is rotatably connected to the middle of the two sets of support frames.

[0008] Preferably, the manual opening and closing assembly includes a sleeve fixedly connected to the outside of the rotating rod, and the manual opening and closing assembly also includes a handle fixedly connected to the outside of the sleeve in a ring shape.

[0009] Preferably, the manual opening and closing assembly further includes a worm gear, which is fixedly connected to the outside of the rotating rod.

[0010] Preferably, the manual opening and closing assembly further includes a rotating shaft, which is rotatably connected to the valve body and the refractory castable. One end of the rotating shaft is fixedly connected to the valve plate, and a worm gear is fixedly connected to the outside of the rotating shaft. The worm gear is in contact with the worm and is meshed and rotatably connected.

[0011] Preferably, the manual opening and closing assembly further includes concave and convex edges, which are formed on both sides of the valve plate.

[0012] Preferably, the valve body assembly further includes a high-temperature resistant rubber pad, which is arranged in a ring and fixedly connected to both sides of the ring groove, and the high-temperature resistant rubber pad and the concave and convex edges are matched in shape.

[0013] Preferably, the slag vibrating assembly includes two sets of built-in seats, which are symmetrically and fixedly connected to the inside of the refractory castable.

[0014] Preferably, the slag-vibrating assembly further includes a sliding plate, which is slidably connected to the center of the built-in seat. The slag-vibrating assembly also includes slag-vibrating plates, which are fixedly connected to both sides of the sliding plate at equal intervals.

[0015] Preferably, the slag vibrating assembly further includes a limiting plate, which is fixedly connected to the outside of the slide plate and the bottom of the limiting plate is in contact with the built-in seat. The slag vibrating assembly also includes an arc edge, which is formed at the bottom of the slide plate.

[0016] The beneficial effects of this utility model are as follows: This design involves casting refractory material inside the valve body and covering the valve plate surface with a layer of refractory and heat-resistant material to form double heat insulation protection. In addition, high-temperature resistant rubber pads are added to both sides of the annular groove to form an elastic seal with the concave and convex edges of the valve plate. The above processes can prevent the valve body and valve plate from being deformed by high temperature, and at the same time prevent slag leakage. In particular, when the valve plate rotates, its concave and convex edges push the arc edge at the bottom of the sliding plate, causing the slag vibrating plate to vibrate up and down, actively loosening the slag. The slag vibrating action is synchronized with the opening and closing of the valve plate, requiring no additional power, with a simple and reliable structure and low maintenance cost.

This design addresses the issues of insufficient high-temperature resistance and increased production and maintenance costs associated with additional power sources for vibration and slag removal in existing technologies through a refractory composite structure and a mechanically linked vibration slag removal design.

[0021] The manual opening and closing assembly 2 also includes a support frame 22, which is symmetrically and fixedly connected to the outside of the valve body 11. The manual opening and closing assembly 2 also includes a rotating rod 23, which is rotatably connected to the middle of the two sets of support frames 22.

[0022] The manual opening and closing assembly 2 includes a sleeve 24, which is fixedly connected to the outside of the rotating rod 23. The manual opening and closing assembly 2 also includes a handle 241, which is fixedly connected to the outside of the sleeve 24 in a ring shape.

[0023] The manual opening and closing assembly 2 also includes a worm gear 231, which is fixedly connected to the outside of the rotating rod 23.

[0024] The manual opening and closing assembly 2 also includes a rotating shaft 25, which is rotatably connected to the valve body 11 and the refractory castable 12. One end of the rotating shaft 25 is fixedly connected to the valve plate 21, and a worm gear 251 is fixedly connected to the outside of the rotating shaft 25. The worm gear 251 is in contact with the worm 231 and is meshed and rotatably connected.

[0025] The manual opening and closing assembly 2 also includes concave and convex edges 2111, which are formed on both sides of the valve plate 21.

[0026] Valve body assembly 1 also includes a high-temperature resistant rubber pad 1211, which is distributed in a ring and fixedly connected to both sides of the ring groove 121. The high-temperature resistant rubber pad 1211 and the concave and convex edges 2111 are matched in shape.

[0027] The vibratory slag assembly 3 includes two sets of built-in seats 31, which are symmetrically fixedly connected to the inside of the refractory castable 12.

[0028] The slag vibrating assembly 3 also includes a slide plate 32, which is slidably connected to the middle of the built-in seat 31. The slag vibrating assembly 3 also includes a slag vibrating plate 33, which is fixedly connected to both sides of the slide plate 32 at equal intervals.

[0029] The slag vibrating assembly 3 also includes a limiting plate 321, which is fixedly connected to the outside of the slide plate 32, and the bottom of the limiting plate 321 contacts the built-in seat 31. The slag vibrating assembly 3 also includes an arc edge 322, which is formed at the bottom of the slide plate 32.

[0030] The working principle and usage process of this utility model are as follows: This design provides a refractory castable 12 on the inner side of the valve body 11 and a refractory and heat-resistant material layer 211 on the outer side of the valve plate 21 to prevent deformation of the two when in long-term contact with high-temperature slag. When it is necessary to discharge slag from the refractory castable 12, the operator can hold the handle 241 and drive the rotating rod 23 and the worm gear 231 to rotate between the two sets of support frames 22. At this time, under the meshing action of the worm gear 231 and the worm wheel 251, the rotating shaft 25 located inside the worm wheel 251 can drive the valve plate 21 to rotate in the annular groove 121. When the valve plate 21 rotates to a vertical position, the slag can fall through the bottom of the valve body 11 to complete the slag discharge work. Specifically, when the valve plate 21 rotates in the annular groove 121, the concave and convex edges 2111 on the side of the valve plate 21 will contact and continuously push the arc edge 322 at the bottom of the slide plate 32. At this time, the slide plate 32 moves vertically back and forth inside the inner seat 31, and the slag is shaken and cleared by the slag vibration plate 33 on the side of the slide plate 32. This design can prevent the slag from getting blocked during the feeding process in the valve body 11. After the slag is discharged from the valve body 11, the handle 241 is turned and the rotating rod 23 is rotated until the valve plate 21 returns to a horizontal state in the annular groove 121. At this time, the annular groove 121 is closed. In particular, the design adopts the meshing rotation design of the worm 231 and the worm wheel 251 to avoid the valve plate 21 from becoming loose after it is closed. Specifically, when the valve plate 21 is horizontally locked in the annular groove 121, the concave and convex edges 2111 on the side of the valve plate 21 will align with the high-temperature resistant rubber pad 1211, thereby effectively preventing slag from falling out from the gap between the valve plate 21 and the annular groove 121.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
