Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically a dustproof slide gate valve. Background Technology

[0002] A slide gate valve is a type of valve commonly used in industrial piping systems. Its main feature is that it controls the flow of fluid by inserting or removing a movable slide. This type of valve has a simple structure, is easy to operate, and is suitable for applications requiring frequent switching. Slide gate valves are widely used in industries such as metallurgy, chemical engineering, and power generation to control the flow of gases, liquids, or powders.

[0003] The slide gate valve has a groove for the valve plate to slide open and close. In order to ensure smooth sliding adjustment of the valve plate, there is usually a certain gap between the valve plate and the inner wall of the groove. When conveying granular or powdery materials, dust will leak to the outside through the above-mentioned gap, causing dust or material leakage and causing pollution to the surrounding environment. Utility Model Content

[0004] The purpose of this utility model is to provide a dustproof slide gate valve, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A dustproof slide gate valve includes a valve body seat and a valve plate. The valve body seat has an inlet on one side and an outlet on the other side. It has a material guide channel inside that connects the inlet and the outlet. The top surface of the valve body seat is provided with a sliding groove that extends vertically downward and passes through the material guide channel. The valve plate is slidably inserted into the sliding groove. One side of the valve body seat is provided with a drive mechanism for driving the valve plate to adjust its lifting and closing. The top of the valve body seat is provided with a dust collection device for absorbing dust leaked from the upper port of the sliding groove.

[0007] Therefore, when dust flows into the gap between the inner wall of the sliding groove and the outer surface of the valve plate, and floats out from the upper port of the sliding groove, the dust can be removed by the dust collection device to avoid polluting the on-site environment.

[0008] Furthermore, the vacuuming device includes a vacuum frame and a vacuum pipe. The vacuum frame is fixed to the top surface of the valve body seat and has a vacuum chamber inside. The inner surface of the vacuum frame is evenly distributed with vacuum holes that communicate with the vacuum chamber. The vacuum pipe is connected to the side of the valve plate and communicates with the vacuum chamber. The end of the vacuum pipe is connected to the vacuum interface of the industrial vacuum cleaner.

[0009] Furthermore, the dust collection frame is rectangular and distributed around the sliding groove port, and the dust collection cavity extends in a rectangular shape and is distributed around the sliding groove port.

[0010] Furthermore, the suction holes are arranged in an array at intervals on the four inner surfaces of the suction frame.

[0011] Furthermore, the drive mechanism includes a pair of brackets, a threaded rod, a nut seat, a first connecting arm, and a drive device. The two brackets are respectively fixed on one side of the valve body seat. The threaded rod is rotatably mounted on the two brackets. The nut seat is threadedly fitted onto the threaded rod. One end of the first connecting arm is fixed to the side of the nut seat, and the other end is fixedly connected to the side of the valve plate and near the top of the valve plate. The drive device is fixed to the bottom of the lower bracket and is used to drive the threaded rod to rotate.

[0012] Furthermore, the drive device uses a drive motor, and the output shaft of the drive motor is fixedly connected to the bottom end of the threaded rod.

[0013] Furthermore, a vertically extending side groove is provided on the side of the valve body seat away from the drive mechanism. A sliding block is slidably installed in the side groove. The top of the sliding block is fixed by a second connecting arm with an L-shaped structure. The top of the second connecting arm is fixedly connected to the side of the valve plate and near the top of the valve plate.

[0014] Furthermore, a vertically extending guide rod is fixed inside the side groove, and a sliding block is slidably fitted onto the guide rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model utilizes the negative pressure generated by the operation of an industrial vacuum cleaner to create a suction airflow that sequentially passes through the suction hole, suction chamber, and suction pipe. This airflow can remove and collect dust leaking from the sliding groove port, thus preventing pollution of the on-site environment.

[0017] 2. The present invention features a rectangular dust collection frame and dust collection chamber that extend around the sliding groove port, forming a barrier around the sliding groove port. The dust collection holes are distributed at intervals on the four inner surfaces of the dust collection frame, achieving a multi-point dust collection effect. This results in a uniform distribution of dust collection capacity, increases the dust collection coverage, effectively enhances the dust collection capacity, and thus improves the dust prevention and dust collection effect of the slide valve.

[0018] 3. This utility model integrates the drive mechanism on one side of the valve body seat. When the valve plate is driven to move downward to the fully closed state, compared with the traditional slide gate valve, the overall volume of this slide gate valve when closed is smaller, the structure is more reasonable, and it is convenient to use.

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] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0026] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] Please see Figures 1-4The present invention provides a dustproof slide gate valve, comprising a valve body seat 1 and a valve plate 2. The valve body seat 1 has an inlet 11 on one side and an outlet 12 on the other side. It has a guide channel 13 inside that connects the inlet 11 and the outlet 12. The top surface of the valve body seat 1 is provided with a sliding groove 101 that extends vertically downward and passes through the guide channel 13. The valve plate 2 is slidably inserted into the sliding groove 101. A drive mechanism 4 is provided on one side of the valve body seat 1 for driving the valve plate 2 to adjust its lifting and lowering. A dust collection device is provided on the top of the valve body seat 1 for absorbing dust leaked from the upper port of the sliding groove 101.

[0028] When the dustproof slide gate valve provided by this utility model is in use, the valve plate 2 is driven to move up and down along the sliding groove 101 by the working of the driving mechanism 4, so as to realize the opening and closing adjustment of the valve plate 2. When the valve plate 2 is open, the material guide channel 13 is open, which can ensure the normal passage of materials. When the valve plate 2 is closed, the material guide channel 13 is blocked, which can block the flow of materials.

[0029] When dust flows into the gap between the inner wall of the sliding groove 101 and the outer surface of the valve plate 2, and floats out from the upper port of the sliding groove 101, the dust can be sucked away by the dust collection device.

[0030] Specifically, the dust collection device includes a dust collection frame 3 and a dust collection pipe 33. The dust collection frame 3 is fixed to the top surface of the valve body seat 1. The dust collection frame 3 has a dust collection channel 31 inside. The inner surface of the dust collection frame 3 is evenly distributed with dust collection holes 32 that communicate with the dust collection channel 31. The dust collection pipe 33 is connected to the side of the valve plate 2 and communicates with the dust collection channel 31. The end of the dust collection pipe 33 is connected to the dust collection interface of the industrial vacuum cleaner (not shown in the figure). The industrial vacuum cleaner adopts existing technology, which will not be described in detail in this application. The industrial vacuum cleaner generates negative pressure during operation, and then the dust collection airflow passes through the dust collection holes 32, the dust collection channel 31 and the dust collection pipe 33 in sequence. This can remove and collect the dust leaking from the port of the sliding groove 101, avoiding pollution to the on-site environment.

[0031] Specifically, the vacuum frame 3 is rectangular and is distributed around the port of the sliding groove 101. The vacuum chamber 31 extends in a rectangular shape and is distributed around the port of the sliding groove 101.

[0032] Specifically, the suction holes 32 are arranged in an array at intervals on the four inner surfaces of the suction frame 3.

[0033] The rectangular dust collection frame 3 and the dust collection chamber 31 are distributed around the port of the sliding groove 101, forming a barrier around the port of the sliding groove 101. The dust collection holes 32 are distributed at intervals on the four inner surfaces of the dust collection frame 3, achieving a multi-point dust collection effect, making the dust collection capacity evenly distributed, increasing the dust collection coverage, effectively improving the dust collection capacity, and thus improving the dust prevention and dust collection effect of this slide valve.

[0034] Specifically, the drive mechanism 4 includes a pair of brackets 41, a threaded rod 42, a nut seat 43, a first connecting arm 44, and a drive device 45. The two brackets 41 are respectively fixed on one side of the valve body seat 1. The threaded rod 42 is rotatably mounted on the two brackets 41. The nut seat 43 is threadedly fitted onto the threaded rod 42. One end of the first connecting arm 44 is fixed to the side of the nut seat 43, and the other end is fixedly connected to the side of the valve plate 2 near the top of the valve plate 2. The drive device 45 is fixed to the bottom of the lower bracket 41 and is used to drive the threaded rod 42 to rotate. The drive device 45 drives the threaded rod 42 to rotate. The rotating threaded rod 42 drives the nut seat 43 to slide up and down along the threaded rod 42. Under the connection of the first connecting arm 44, it can drive the valve plate 2 to adjust up and down, providing drive for the lifting and opening adjustment of the valve plate 2.

[0035] In addition, the drive mechanism 4 is integrated on one side of the valve body seat 1. When the valve plate 2 is driven to move downward to the fully closed state, the overall volume of this slide gate valve is smaller when closed compared to the traditional slide gate valve. The structure is reasonable and easy to use.

[0036] Specifically, the drive device 45 uses a drive motor. The output shaft of the drive motor is fixedly connected to the bottom end of the threaded rod 42. When the drive motor works, its output shaft drives the threaded rod 42 to rotate, providing drive for the lifting and lowering adjustment of the nut seat 43.

[0037] Specifically, the valve body seat 1 has a vertically extending side groove 5 on the side away from the drive mechanism 4. A sliding block 51 is slidably installed in the side groove 5. The top of the sliding block 51 is fixed by a second connecting arm 52 with an L-shaped structure. The top of the second connecting arm 52 is fixedly connected to the side of the valve plate 2 and close to the top of the valve plate 2. When the valve plate 2 is adjusted by lifting, the sliding block 51 can be driven to slide synchronously along the inner wall of the side groove 5 under the connection of the second connecting arm 52. The sliding cooperation between the sliding block 51 and the inner wall of the side groove 5 provides an auxiliary guiding and limiting function for the lifting of the valve plate 2, ensuring that the lifting of the valve plate 2 is smooth and stable enough.

[0038] Specifically, a vertically extending guide rod 511 is fixed inside the side groove 5, and the sliding block 51 is slidably fitted onto the guide rod 511. By slidably fitting the sliding block 51 into the guide rod 511, the sliding block 51 can be limited and slidably installed, preventing the sliding block 51 from sliding out of the side groove 5, and further ensuring the stability of the sliding lifting adjustment of the valve plate 2.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
