Description

Technical Field

[0001] This utility model relates to the field of surface spraying technology, specifically to a wear-resistant ball valve ball spraying device. Background Technology

[0002] Wear-resistant ball valves are widely used in several key industries, including polysilicon, organosilicon, petrochemicals, and coal chemicals, due to their excellent wear resistance, sealing performance, erosion resistance, and corrosion resistance. The wear-resistant coating and surface treatment of wear-resistant ball valves require the use of hard alloys with sufficient hardness to ensure that the valve maintains good wear resistance, erosion resistance, and sealing performance under high-speed fluid erosion and solid particle impact. Wear-resistant ball valve ball spraying equipment is used to uniformly coat the surface of the ball valve ball with wear-resistant materials; its design purpose is to improve the ball's wear resistance, corrosion resistance, and sealing performance.

[0003] In the existing technology, wear-resistant ball valve ball spraying devices generally adopt an intermittent operation logic of single-group fixing, single spraying, and individual replacement when performing spraying work. Most of them fix a group of balls, then spray the balls through the nozzle, and then remove them and replace them with another group of balls for spraying, which is relatively inefficient. Utility Model Content

[0004] To overcome the above-mentioned defects, the present invention provides a wear-resistant ball valve ball spraying device, which solves the technical problem of low efficiency in the intermittent operation of single-group fixed, single-spray, and individual replacement in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a wear-resistant ball valve ball spraying device, comprising: The box has a rotating component fixedly installed on one inner wall, a spraying component is provided behind the rotating component, a limiting groove is opened on the inner wall of the box outside the rotating component, and a sliding groove is opened through one side of the limiting groove. The fixing components are provided in four sets, and the four sets of fixing components are fixedly connected to one end of the rotating component. A baffle is provided on the side of the four sets of fixing components that are close to each other. A support component, one end of which is slidably mounted in a sliding groove, and the other end of which is fixedly connected to the rotating component.

[0006] For example, in a wear-resistant ball valve ball spraying device provided in at least one embodiment of the present invention, the rotating component further includes a fixed column, one end of which is fixedly connected to the output end of a first motor, a connecting plate is provided on the outer surface of the fixed column, and a second motor is provided at the end of the connecting plate away from the first motor.

[0007] For example, in a wear-resistant ball valve ball spraying device provided in at least one embodiment of the present invention, four connecting plates are provided, one end of each of the four connecting plates is fixedly installed at equal intervals on the outer surface of the fixed column, and the rear end of the second motor is fixedly installed on the other end of the connecting plates.

[0008] For example, in a wear-resistant ball valve ball spraying device provided in at least one embodiment of the present invention, the support components are provided in four sets, and the four sets of support components are respectively located on the side of the four connecting plates near the first motor. The other end of the support component is fixedly connected to the side wall of the connecting plate near the first motor.

[0009] For example, in a wear-resistant ball valve ball spraying device provided in at least one embodiment of the present invention, the fixing component includes a fixing cylinder, one end of the fixing cylinder is fixedly connected to the output end of a second motor, and the other end of the fixing cylinder has symmetrically opened receiving grooves on its outer surface. A spring is provided in the receiving groove, and a stop plate is provided at the upper end of the receiving groove. One end of the stop plate is located inside the receiving groove and is fixedly connected to the upper end of the spring, and the lower end of the spring is fixedly connected to the bottom wall of the receiving groove.

[0010] For example, in a wear-resistant ball valve ball spraying device provided in at least one embodiment of the present invention, the upper surface of the abutment plate is provided with a number of anti-slip protrusions.

[0011] For example, in a wear-resistant ball valve ball spraying device provided in at least one embodiment of the present invention, a fixing plate is fixedly installed at the middle position of one side wall of the connecting plate near the fixing cylinder, and a baffle is fixedly installed at the other end of the fixing plate, the baffle being arc-shaped.

[0012] For example, in a wear-resistant ball valve ball spraying device provided in at least one embodiment of the present invention, the spraying assembly includes two fixing blocks. One end of the two fixing blocks is fixedly installed on the rear wall of the housing, and an arc plate is fixedly installed on the other end of the two fixing blocks. A bent pipe is fixedly connected to one side wall of the arc plate near the fixing block. A connecting pipe is sealed to one side surface of the bent pipe. The other end of the connecting pipe extends through the housing to the outside. Three spray nozzles are equidistantly sealed to the surface of the bent pipe, and all three spray nozzles penetrate the arc plate.

[0013] The beneficial effects of this utility model are as follows: (1) In this utility model, the first motor drives the connecting plate, the second motor and the fixing component to rotate through the fixed column to replace the ball for spraying.

The second motor is connected to the fixing component and can independently control the rotation speed of the ball. The four equidistant connecting plates and the second motor can fix the four balls. The first motor drives the fixed column to rotate, and at the same time each second motor can independently drive the corresponding ball to rotate, and spray the four balls at the same time, which improves the spraying efficiency to a certain extent.

[0014] (2) In this utility model, when clamping, the inner hole of the ball is first pushed into the fixed cylinder. The surface of the inner hole of the ball will press the abutment plate, causing the abutment plate to shrink into the receiving groove. At the same time, the spring is compressed. The rebound force generated by the spring will push the abutment plate to press tightly against the surface of the inner hole of the ball, forming an elastic clamping, ensuring that the ball is stably fixed. The whole process does not require tools such as wrenches and screwdrivers, shortening the clamping time and greatly improving the efficiency of changing parts. The spring and the abutment plate are vulnerable parts. If wear or elastic failure occurs, they can be replaced separately to reduce the replacement cost. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0019] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0023] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] like Figures 1-4 As shown, it illustrates a wear-resistant ball valve ball spraying device in one embodiment of the present invention. A rotating component 2 is fixedly installed on the inner wall of the housing 1, and a spraying component 6 is arranged behind the rotating component 2.

[0025] The housing 1 is the basic frame of the entire device. The rotating component 2, the spraying component 6, etc. are all installed on the inner wall or inside the housing 1. Their function is to provide installation support for each component and form a relatively closed spraying environment.

[0026] Rotating component 2 drives the sphere to be sprayed to rotate, ensuring that the surface of the sphere can be sprayed as evenly as possible.

[0027] The fixing component 4 is provided in four sets. The four sets of fixing components 4 are fixedly connected to one end of the rotating component 2. A baffle 5 is provided on the side of the four sets of fixing components 4 that are close to each other. The fixing components 4 are used to clamp and fix the ball to be sprayed. When the first motor 201 starts, it will drive the fixing components 4 to rotate through the output shaft, so that the ball rotates synchronously with the fixing components 4, so that each area of ​​the ball surface can pass through the spraying component 6 in sequence to achieve uniform spraying.

[0028] Support component 3 is slidably installed in sliding groove 8 at one end and fixedly connected to rotating component 2 at the other end. The function of support component 3 is to support the ball from the other side and cooperate with rotating component 2 to ensure that the ball does not wobble or deviate when rotating. Support shaft 301 can be made of metal, which can ensure the safety of the spraying process for balls with large weight.

[0029] This device uses the housing 1 as the basic frame. Through the coordinated operation of the rotating component 2, the supporting component 3 and the fixed component 4, it provides stable rotation conditions for the workpiece to be sprayed. The rotating component 2 drives the four fixed components 4 to rotate. After one group of balls completes the spraying work, it is rotated to rotate another group of fixed components 4 into the working range of the spraying component 6. At the same time, the spraying component 6 achieves precise spraying, which can improve the spraying efficiency to a certain extent.

[0030] In some examples, such as Figure 2As shown, the first motor 201 drives the connecting plate 203, the second motor 204 and the fixing component 4 to rotate through the fixing column 202 to replace the ball for spraying. The second motor 204 can drive the fixing component 4 and the ball to rotate, so that the ball can be evenly exposed within the spraying range of the spraying component 6. The second motor 204 is connected to the fixing component 4 and can independently control the rotation speed of the ball, extending or shortening the single spraying time to ensure that the coating thickness is appropriate.

[0031] In some examples, such as Figure 2 As shown, four equidistant connecting plates 203 and a second motor 204 can fix four spheres. The first motor 201 drives the fixed column 202 to rotate, and the four spheres will move in a circle with the fixed column 202. At the same time, each second motor 204 can independently drive the corresponding sphere to rotate, which can perform spraying operations on the four spheres at the same time, increase the production capacity per unit time, and improve the spraying efficiency to a certain extent.

[0032] In some examples, such as Figure 3 As shown, the four sets of support components 3 correspond to four connecting plates 203. They are fixedly connected to the connecting plates 203 through the support shaft 301. During spraying, the support shaft 301 can be locked inward, and the four spheres provide stable support, preventing the connecting plates 203 from bending and deforming due to excessive force.

[0033] In some examples, such as Figure 2 and 4 As shown, during clamping, the inner hole of the ball is pushed into the fixing cylinder 401. The surface of the inner hole of the ball will press against the abutment plate 404, causing the abutment plate 404 to contract into the receiving groove 402. At the same time, the spring 403 is compressed. The rebound force generated by the spring 403 will push the abutment plate 404 to press tightly against the surface of the inner hole of the ball, forming an elastic clamping, ensuring that the ball is stably fixed. The fixing cylinder 401 is fixedly connected to the output end of the second motor 204. When the second motor 204 drives the ball to rotate, the abutment plate 404 is in close contact with the surface of the ball, and the ball rotates synchronously and stably with the second motor 204, providing a foundation for subsequent uniform spraying.

[0034] When the ball is inserted, the spring 403 automatically retracts. When the ball is removed, the spring 403 automatically resets and clamps. The whole process does not require tools such as wrenches and screwdrivers, which shortens the clamping time and improves the efficiency of changing parts. At the same time, the spring 403 and the abutment plate 404 are vulnerable parts. If wear or elasticity failure occurs, they can be replaced separately, which can reduce replacement costs.

[0035] In some examples, such as Figure 4 As shown, the anti-slip protrusion 405 is hemispherical. Multiple sets of anti-slip protrusions 405 increase the number of contact points between the abutment plate 404 and the sphere, which can disperse local pressure and also increase friction.

[0036] In some examples, such as Figure 2 As shown, when the spraying component 6 is working, the paint may be sprayed onto the surface of the sphere at high speed. Some unattached paint will splash to the surroundings. The arc-shaped baffle 5 forms a semi-enclosed shape from the side, blocking the splashed paint inside the baffle 5 and reducing the amount of cleaning work inside the box 1.

[0037] In some examples, such as Figure 2 and 4 As shown, the distance between the outer surface of the sphere and the arc plate 601 is always consistent, and the distance between the nozzle 604 and the surface of the sphere is also always constant. This avoids the uneven coating caused by the rotation of the sphere due to the traditional flat nozzle 604. The three nozzles 604 can cover a larger area, reduce the blind zone of the traditional single nozzle 604, and ensure that the surface of the sphere is uniformly coated to a certain extent.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
