Description

Technical Field

[0001] This utility model relates to the field of feed valve technology, specifically a wear-resistant ceramic rotary feed speed regulating valve. Background Technology

[0002] The ceramic rotary feed speed control valve is a valve made of cast steel and wear-resistant ceramics. It uses a pneumatic actuator to drive a rotary shaft to move the valve plate, thereby opening and closing the valve. It is mainly suitable for opening, closing and speed control of abrasive and corrosive dust media in power plant dry ash systems, mines, petrochemical plants and other applications. It features good sealing performance, high temperature resistance, strong wear resistance, flexible opening and closing, and long service life.

[0003] Chinese patent CN215293790U discloses a wear-resistant ceramic rotary feed valve. This feed valve, by setting up a clearing rod and other structures, allows the ceramic material accumulated in the feed pipe to be cleared by moving the clearing rod in the feed pipe when the material is input by an air pump. This avoids the possibility of pipe blockage affecting the normal use of the rotary valve and achieves the function of enabling the rotary valve to work normally.

[0004] However, in the aforementioned patent, the unblocking rod is located inside the telescopic hose, which interferes with the flow of materials to a certain extent, causing the materials to be obstructed during the flow process. This is especially true when the material particles are large or have poor flowability, making blockage more likely. Furthermore, the telescopic hose deforms up and down under the influence of the connecting rod, resulting in uneven stress on the hose. Over time, this can easily lead to damage and material leakage. Utility Model Content

[0005] The purpose of this invention is to provide a wear-resistant ceramic rotary feed speed control valve, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A wear-resistant ceramic rotary feed speed regulating valve includes a rotary valve body. An inlet pipe and an outlet pipe are connected to the upper and lower sides of the rotary valve body, respectively. A housing is installed on the outer surface of the inlet pipe. Multiple tube bodies are coaxially arrayed on the outer surface of the inlet pipe inside the housing. A striking rod is installed inside each tube body. Multiple sets of striking mechanisms are installed inside the housing, each set corresponding to one of the striking rods. The striking mechanisms drive the striking rods to strike the outer surface of the inlet pipe. A transmission mechanism is provided between the multiple sets of striking mechanisms, and a drive mechanism is installed inside the housing.

[0008] It can be seen that through the cooperation between the striking mechanism, the transmission mechanism and the drive mechanism, multiple striking rods can be driven to intermittently strike the outer surface of the feed tube at the same time. The vibration generated by the striking can promote the smooth flow of materials inside the feed tube, avoid blockage, and does not occupy the internal space of the feed tube, and will not obstruct the flow path of materials, thus reducing the risk of material blockage and retention.

[0009] Furthermore, the striking mechanism includes two side plates installed inside the housing, with a rotating shaft rotatably connected between the opposing surfaces of the two side plates. A cam is installed on the outer surface of the rotating shaft, and the cam corresponds to the striking rod. One end of the rotating shaft extends through to the outer side of the side plate and is equipped with a first transmission bevel gear.

[0010] Furthermore, the transmission mechanism includes a fixed plate mounted on the upper surface of the side plate, a connecting shaft that is rotatably mounted through the fixed plate, a second transmission bevel gear mounted on the lower end of the connecting shaft, and the second transmission bevel gear meshing with the first transmission bevel gear, a pulley mounted on the upper end of the connecting shaft, and a transmission belt that meshes with the outer surfaces of multiple pulleys.

[0011] Furthermore, the drive mechanism includes a motor mounted on the outer surface of the housing, with the end of the motor output shaft extending into the interior of the housing and fitted with a drive bevel gear, and the other end of one of the shafts extending into the outer side of the side plate and fitted with a driven bevel gear, the driven bevel gear meshing with the drive bevel gear.

[0012] Furthermore, the inner wall of the tube is provided with a recess, the outer surface of the striking rod is provided with a shoulder, and a spring is sleeved on the outer surface of the striking rod, with the two ends of the spring abutting against the shoulder and the inner wall of the recess, respectively.

[0013] Furthermore, a silicone pad is provided at the end of the striking rod facing the feed tube.

[0014] Furthermore, a ball bearing is provided at the end of the striking rod away from the feed tube.

[0015] Furthermore, flanges are provided at the ends of both the feed pipe and the discharge pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0017] 1. This utility model, through the cooperation of the striking mechanism, the transmission mechanism and the driving mechanism, can simultaneously drive multiple striking rods to intermittently strike the outer surface of the feed tube. The vibration generated by the striking promotes the smooth flow of materials inside the feed tube, avoids blockage, does not occupy the internal space of the feed tube, and does not obstruct the flow path of materials, thus reducing the risk of material blockage and retention.

[0018] 2. This utility model utilizes a spring mechanism. When the striking rod is compressed by the cam and moves rapidly toward the feed pipe, it compresses the spring by driving the shoulder. After the end of the striking rod strikes the outer surface of the feed pipe, the striking rod can be quickly reset through the interaction of the rebound force and the spring force. Therefore, with the rotating shaft driving the cam to rotate rapidly, the striking rod can be driven to stably and intermittently strike the outer surface of the feed pipe, achieving stable vibration and ensuring the smooth flow of materials.

Detailed Implementation

[0026] 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.

[0027] 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.

[0028] 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.

[0029] Please see Figures 1-6 This utility model provides a wear-resistant ceramic rotary feed speed regulating valve, including a rotary valve body 100. A feed pipe 101 and a discharge pipe 102 are respectively connected to the upper and lower sides of the rotary valve body 100. A housing 103 is installed on the outer surface of the feed pipe 101. Multiple tube bodies 104 are coaxially arrayed on the outer surface of the feed pipe 101 inside the housing 103. A striking rod 105 is disposed inside the tube body 104. Multiple sets of striking mechanisms 200 are disposed inside the housing 103, each set corresponding to one striking rod 105. The striking mechanisms 200 can drive the striking rods 105 to strike the outer surface of the feed pipe 101. A transmission mechanism 300 is disposed between the multiple sets of striking mechanisms 200, and a drive mechanism 400 is disposed inside the housing 103.

[0030] During use, the striking mechanism 200, transmission mechanism 300, and drive mechanism 400 work together to drive multiple striking rods 105 to intermittently strike the outer surface of the feed pipe 101 during material flow. The vibration generated by the striking promotes the smooth flow of material inside the feed pipe 101 and prevents blockage. Furthermore, when the rotary valve body 100 has not been used for a long time, causing the material to be tightly compacted under its own weight, the striking rods 105 can also strike the outer surface of the feed pipe 101. The vibration generated by the striking will disperse large pieces of material, especially those materials that are prone to blockage due to particle shape, size, or humidity, ensuring their smooth flow and preventing blockage. The number of pipes 104 can be reasonably selected according to the diameter of the feed pipe 101, and can be 8, 9, 10, etc.

[0031] Specifically, the striking mechanism 200 includes two side plates 201 installed inside the housing 103. A rotating shaft 202 is rotatably connected between the opposite surfaces of the two side plates 201. A cam 203 is installed on the outer surface of the rotating shaft 202. The cam 203 corresponds to the striking rod 105. One end of the rotating shaft 202 extends to the outside of the side plate 201 and is equipped with a first transmission bevel gear 204. When the rotating shaft 202 rotates rapidly, it drives the cam 203 to squeeze the striking rod 105. After being squeezed, the striking rod 105 moves rapidly toward the feed pipe 101 and strikes its surface, generating vibration, thereby promoting the smooth flow of material inside the feed pipe 101.

[0032] Specifically, the transmission mechanism 300 includes a fixed plate 305 mounted on the upper surface of the side plate 201. A connecting shaft 302 is rotatably mounted through the fixed plate 305. A second transmission bevel gear 301 is mounted on the lower end of the connecting shaft 302, and the second transmission bevel gear 301 meshes with the first transmission bevel gear 204. A pulley 303 is mounted on the upper end of the connecting shaft 302. A transmission belt 304 is fitted onto the outer surfaces of multiple pulleys 303. Through the meshing relationship between the first transmission bevel gear 204 and the second transmission bevel gear 301, the connecting shaft 302 can be driven to rotate when the rotating shaft 202 rotates. Through the arrangement of the transmission belt 304 and the pulleys 303, multiple connecting shafts 302 can rotate simultaneously, thereby driving multiple rotating shafts 202 to rotate simultaneously. Therefore, by driving one rotating shaft 202 to rotate through the drive mechanism 400, multiple rotating shafts 202 can be driven to rotate simultaneously, thereby achieving the purpose of transmission.

[0033] Specifically, the drive mechanism 400 includes a motor 401 mounted on the outer surface of the housing 103. The end of the output shaft of the motor 401 extends into the interior of the housing 103 and is fitted with a drive bevel gear 402. The other end of one of the rotating shafts 202 extends into the outer side of the side plate 201 and is fitted with a driven bevel gear 403. The driven bevel gear 403 meshes with the drive bevel gear 402. When the motor 401 starts, its output shaft drives the drive bevel gear 402 to rotate. Since the drive bevel gear 402 and the driven bevel gear 403 mesh with each other, the rotating shaft 202 fitted with the driven bevel gear 403 can be rotated. Through the transmission action of the transmission mechanism 300, multiple rotating shafts 202 can be driven to rotate simultaneously.

[0034] Specifically, the inner wall of the tube body 104 is provided with a recess 500, the outer surface of the striking rod 105 is provided with a shoulder 501, and a spring 502 is sleeved on the outer surface of the striking rod 105. The two ends of the spring 502 abut against the shoulder 501 and the inner wall of the recess 500, respectively. When the striking rod 105 is squeezed by the cam 203 and moves rapidly toward the feed tube 101, it drives the shoulder 501 to compress the spring 502. When the end of the striking rod 105 strikes the outer surface of the feed tube 101, the striking rod 105 can be driven to quickly return to its original position through the interaction of the rebound force and the elastic force of the spring 502. Therefore, when the rotating shaft 202 drives the cam 203 to rotate rapidly, the striking rod 105 can be driven to stably and intermittently strike the outer surface of the feed tube 101, achieving stable vibration and ensuring the smooth flow of materials.

[0035] Specifically, a silicone pad 600 is provided at the end of the striking rod 105 facing the feed tube 101. The silicone pad 600 can provide buffer protection when the striking rod 105 strikes the outer surface of the feed tube 101, thus preventing damage and deformation to the feed tube 101.

[0036] Specifically, the end of the striking rod 105 away from the feed tube 101 is provided with a ball bearing 700. By setting the ball bearing 700, the frictional resistance between the striking rod 105 and the cam 203 can be reduced, so that the striking rod 105 can strike the outer surface of the feed tube 101 more smoothly.

[0037] Specifically, flanges are provided at the ends of both the feed pipe 101 and the discharge pipe 102, which facilitates the installation of the rotary valve body 100.

[0038] 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.
