Description

Technical Field

[0001] The invention relates to the technical field of decontamination and cleaning, and in particular to a valve fitting cleaning device. Background Art

[0002] Valve accessories usually include valve stems, valve cores, valve seats, glands and other metal parts. During the processing, metal scraps, oil stains, dust and other debris will remain on the surface of valve accessories. If these debris are not removed, they will affect the sealing performance, transmission accuracy and service life of the valve. Therefore, after the processing, valve accessories are generally cleaned with an ultrasonic cleaner. The ultrasonic cleaner can generate high-frequency vibrations and form countless tiny bubbles in the cleaning fluid. These bubbles will generate a strong impact when they burst, shaking off and cleaning the debris on the surface of the valve accessories.

[0003] Generally, batches of valve parts are placed in a cleaning basket for cleaning, but the accumulation of valve parts will result in poor cleaning effect. To this end, a utility model patent with authorization announcement number CN221657386U discloses an ultrasonic decontamination device, which includes an ultrasonic cleaning machine body, a base fixed to the bottom of the ultrasonic cleaning machine body, a lifting device arranged on the base, and a metal part placement device arranged inside the ultrasonic cleaning machine body, the lifting device is connected to the metal part placement device, and the lifting device drives the metal part placement device to rise and fall. Among them, the metal part placement device includes a grid cage that can be placed in the ultrasonic cleaning machine body, and the grid cage is provided with a first grid plate and a second grid plate distributed up and down. When in use, the first grid plate and the second grid plate are both used to place metal parts, thereby realizing the layered placement of metal parts.

[0004] In the prior art, the cleaning effect can be improved by placing metal parts in layers. However, when applied to the cleaning of valve accessories, due to the residual oil on the surface of the valve accessories, the oil floats on the surface of the cleaning liquid after cleaning. When the valve accessories are taken out upwards, the oil on the surface of the cleaning liquid will adhere to the surface of the valve accessories again, causing secondary pollution. Summary of the invention

[0005] The invention provides a valve fitting cleaning device to solve the technical problem in the prior art that oil stains are easily adhered to the surface of cleaning liquid when the valve fitting is taken out upwards, thus causing secondary pollution.

[0006] In order to solve the above problems, the valve parts cleaning device provided by the present invention adopts the following technical scheme: the valve parts cleaning device comprises an ultrasonic cleaning machine and a bearing module which is lowered and lifted during ultrasonic cleaning, the bearing module comprises an outer cylinder, a discharge port sealing plate, a limit block located in the outer cylinder, an inner bearing cylinder, and a material receiving mesh plate, a discharge port corresponding to the material receiving mesh plate is provided on one side of the bottom of the outer cylinder, and the discharge port sealing plate is installed on the outer cylinder to close the discharge port; there are two limit blocks arranged at intervals on the left and right, the two limit blocks are fixed on the outer cylinder and respectively fit with the left and right inner walls of the outer cylinder, arc surfaces are provided on the opposite sides of the two limit blocks, the two arc surfaces are located in the same circular trajectory, the inner bearing cylinder is adaptively rotated around the axis extending forward and backward and assembled between the arc surfaces of the two limit blocks, the limit block and the front and rear ends of the inner bearing cylinder are both fitted with the inner wall of the outer cylinder; the outer cylinder and the discharge port sealing plate are surrounded to form an installation space which is closed on all sides, the top of the installation space extends to the top surface of the limit block, and the bottom extends to the bottom of the material receiving mesh plate; The inner bearing cylinder includes a C-shaped cylinder body with an opening on one side and a supporting mesh plate. The C-shaped cylinder body includes a closed section opposite to the opening and mesh sections arranged on both sides of the closed section. One end of the supporting mesh plate is fixed on the inner side of the closed section and the other end extends toward the opening. When the inner bearing cylinder rotates, it has a discharge position with the opening facing upward, a cleaning position with the supporting mesh plate arranged horizontally, and a closed position with the opening facing downward and the closed section closing the channel between the two limit blocks to close the top opening of the installation space.

[0007] When in use, first rotate the inner bearing cylinder to the discharge position, put the valve accessories into the inner bearing cylinder, and then rotate the inner bearing cylinder to the cleaning position. During the rotation process, the support mesh plate gradually rotates to a horizontal state, so that the valve accessories are supported on the support mesh plate. Through the support mesh plate, the internal space of the inner bearing cylinder can be layered, and layered cleaning is achieved to improve the cleaning effect. After the cleaning is completed, the inner bearing cylinder is rotated to the closed position, the closed section closes the passage between the two limit blocks, and the valve accessories fall on the support mesh plate. In the present invention, since the outer cylinder and the discharge port sealing plate together form an installation space that is closed on all sides, the ends of the inner bearing cylinder and the limit blocks are fitted with the inner side of the outer cylinder, and the valve accessories on the support mesh plate are located in the installation space. When the inner bearing cylinder is in the closed position, the closed section and the two limit blocks close the top opening of the installation space. In the process of lifting the carrying module, the oil stains directly above the carrying module will fall on the outside of the top of the limit block and the closed section. The oil stains between the carrying module and the ultrasonic cleaning machine are always located outside the outer cylinder and the discharge port sealing plate. The oil stains on the surface of the cleaning liquid cannot enter the interior of the installation space, ensuring that the valve accessories will not be contaminated for the second time.

[0008] As a further improvement, there are at least two supporting mesh plates arranged in parallel, and the end portion of each supporting mesh plate away from the closed section is located in the circular trajectory, and a placement space for valve accessories is formed between two adjacent supporting mesh plates and between the supporting mesh plate and the mesh section.

[0009] As a further improvement, oil holes are provided on the left and right sides of the top of the outer cylinder, and the bottom hole edges of the oil holes are arranged flush with the limit blocks; the oil holes are used to provide oil discharge from the limit blocks and the top of the closed section on the supporting module.

[0010] As a further improvement, the top surface of the limit block is arranged tilted from top to bottom and toward the oil through hole. The tilted top surface of the limit block is conducive to the automatic flow of oil to the oil through hole.

[0011] As a further improvement, the inner bearing cylinder is rotatably assembled on the outer cylinder through a rotating shaft that passes through the outer cylinder. The valve fitting cleaning device includes a driving mechanism for driving the inner bearing cylinder to rotate. The driving mechanism includes a gear fixed on the rotating shaft and located outside the outer cylinder and a sliding seat. The sliding seat is slidably assembled on the ultrasonic cleaning machine along the left and right directions. The sliding seat includes a vertical plate located on the inner side of the ultrasonic cleaning machine. The vertical plate is provided with a groove for the gear to enter. The two opposite groove walls of the groove are respectively provided with a first rack and a second rack, and the first rack is located above the second rack. When sliding, the sliding seat has a first position in which the first rack is meshed with the lowered gear and a second position in which the second rack is meshed with the lifted gear. When lowering, the first rack is meshed with the gear, driving the gear and the inner bearing cylinder to rotate in one direction, thereby rotating from the placement position to the cleaning position; when lifting, the second rack is meshed with the gear, driving the gear and the inner bearing cylinder to continue to rotate in this direction, thereby rotating from the cleaning position to the closed position, and then gradually separating from the cleaning liquid. On the one hand, through the meshing of gears and racks, there is no need for manual rotation; on the other hand, no additional power source is required, saving costs.

[0012] As a further improvement, a receiving groove for receiving the vertical plate is provided on the inner side of the ultrasonic cleaning machine.

[0013] As a further improvement, two gears are symmetrically arranged, and one of the two gears is used to mesh with the first rack and the second rack.

The mesh plate spring ensures that the second mesh plate is always supported on the support plate, and the supporting mesh plate is arranged tilted as a whole, so that the valve fittings automatically slide toward the material outlet.

[0015] As a further improvement, the bearing module includes a filter screen plate located below the material receiving screen plate, the filter screen plate is used to filter the cleaned debris, the outer cylinder is provided with a debris discharge port, a debris box is installed in the debris discharge port, and the debris box is used to collect debris on the filter screen plate.

[0016] As a further improvement, the outer cylinder includes a top enclosure frame located at the top, a bottom enclosure frame located at the bottom, and a connecting spring connecting the top enclosure frame and the bottom enclosure frame, the top of the bottom enclosure frame is telescopically assembled in the top enclosure frame and is sealed with the top enclosure frame, the material receiving mesh plate and the filter mesh plate are both arranged in the bottom enclosure frame, and the left and right inner sides of the bottom of the top enclosure frame are both provided with inclined grooves, and the inclined grooves are inclined from top to bottom and toward the impurity discharge port; The bearing module also includes a scraper extending in the left-right direction, and both ends of the scraper are provided with square pins, which pass through the bottom frame and extend into the inclined slot in an adaptive manner. When the bottom frame slides downward, the scraper is driven to move through the inclined slot and the square pin to scrape the debris on the filter screen into the debris box. After the inclined slot and the square pin are provided, the scraper is driven to move and the debris is scraped off by utilizing the characteristic that the bottom frame floats downward after the valve fittings fall on the supporting screen, which makes it more convenient to use.

[0017] The beneficial effects are: 1. When in use, first rotate the inner bearing cylinder to the discharge position, put the valve accessories into the inner bearing cylinder, and then rotate the inner bearing cylinder to the cleaning position.

[0034] There are two limit blocks 202, which are fixed to the inner sides of the left side plate and the right side plate of the top frame 209, respectively. Specifically, they can be fixed by welding or countersunk bolts. The two limit blocks 202 have the same structure and are arranged at intervals along the left and right directions. The limit blocks 202 fit with the left side plate and the right side plate, and the front and rear end surfaces of the limit blocks 202 fit with the front side plate and the rear side plate in the top frame 209. An arc surface 220 is provided on the opposite side of the limit blocks 202. The arc surface 220 of the left limit block 202 is concave to the left, and the arc surface 220 of the right limit block 202 is concave to the right. The arc surfaces 220 of the two limit blocks 202 are arranged oppositely, and the two arc surfaces 220 are located in the circumferential trajectory of the same circle.

[0035] The stopper 202 has an inclined top surface 221, and the inclination direction of the top surface 221 is from top to bottom and toward the side plate on the side, that is, the top surface 221 of the left stopper 202 is inclined from top to bottom and toward the left, and the top surface 221 of the right stopper 202 is inclined from top to bottom and toward the right.

[0037] The inner bearing tube 203 is adapted to rotate around the axis extending forward and backward and is installed between the two limit blocks 202. The adaptation here means that the outer circumference of the inner bearing tube 203 is located in the circumferential track where the arc surface 220 of the two limit blocks 202 is located. In actual processing, there is usually a clearance fit between the outer circumference of the inner bearing tube 203 and the arc surface 220 of the limit block 202 to ensure that the inner bearing tube 203 can rotate smoothly. The front and rear end surfaces of the inner bearing tube 203 are respectively fitted with the front side plate and the rear side plate of the top frame 209.

[0038] The inner bearing cylinder 203 includes a C-shaped cylinder 223, a supporting mesh plate, and a rotating shaft 224. The outer circumference of the C-shaped cylinder 223 is located in the circumferential track where the arc surface 220 is located, and one side of the C-shaped cylinder 223 is open to form a C-shaped structure. The C-shaped cylinder 223 includes a closed section 225 and two mesh sections 226. The outer circumference of the closed section 225 is closed, and the closed section 225 is directly opposite to the opening of the C-shaped cylinder 223. The inner side of the closed section 225 is a plane, which is convenient for installing the supporting mesh plate; the mesh section 226 is provided with mesh holes for the cleaning liquid to pass through, and the two mesh sections 226 are located on both sides of the closed section 225.

[0039] There are five supporting mesh plates here, which are vertically fixed on the inner plane of the closed section 225, and the spacing arrangement direction of the five supporting mesh plates is consistent with the spacing arrangement direction of the two mesh sections 226. One end of the supporting mesh plate is fixed on the closed section 225, and the other end extends to the opening of the C-shaped cylinder 223.

[0040] Here, for the convenience of description, five support mesh plates are defined as the first support mesh plate 227 located in the middle, the two second support mesh plates 228 located on both sides of the first support mesh plate 227, and the third support mesh plate 229 located between the second support mesh plate 228 and the mesh section 226, wherein the length of the first support mesh plate 227 is greater than the length of the second support mesh plate 228, and the length of the second support mesh plate 228 is greater than the length of the third support mesh plate 229. The distance between the two second support mesh plates 228 is less than the distance between the top surfaces of the two limit blocks 202, so that the staff can put the valve accessories into the interval between the second support mesh plate 228 and the third support mesh plate 229. The ends of the first support mesh plate 227, the second support mesh plate 228, and the third support mesh plate 229 are located in the circumferential track where the outer peripheral surface of the C-shaped cylinder 223 is located. The third support mesh plate 229 connects the closed section 225 and the mesh section 226. The first supporting mesh plate 227 , the second supporting mesh plate 228 , and the third supporting mesh plate 229 are all provided with mesh holes for the cleaning liquid to pass through.

[0041] There are two rotating shafts 224, which are respectively fixed on the front and rear sides of the first supporting mesh plate 227, and the two rotating shafts 224 are coaxially arranged. The rotating shaft 224 is used to penetrate the rotating shaft through hole 236 of the top frame 209, and the rotating shaft 224 and the rotating shaft through hole 236 are sealed, which can be achieved by setting a sealing ring.

[0042] The material receiving mesh plate 204 is located in the bottom enclosure 210 and is arranged tilted as a whole.

Both ends of the hinge shaft 230 are inserted into the hinge shaft through hole 216 of the bottom enclosure 210, one end of the first mesh plate 231 is fixed on the hinge shaft 230, the second mesh plate 232 is telescopically assembled in the other end of the first mesh plate 231, and the mesh plate spring 233 is fixed between the first mesh plate 231 and the second mesh plate 232. The mesh plate spring 233 here is a compression spring, which can apply force to the second mesh plate 232 so that the second mesh plate 232 extends out of the first mesh plate 231.

[0043] The first mesh plate 231 and the second mesh plate 232 are both provided with mesh holes, and the mesh holes on the first mesh plate 231 and the second mesh plate 232 allow debris and cleaning fluid to pass through, but valve accessories cannot pass through.

[0044] The discharge port sealing plate 205 is used to seal the discharge port 218. A support plate 234 is fixed to the inner bottom of the discharge port sealing plate 205. One end of the second mesh plate 232 is pressed against the inner side of the discharge port sealing plate 205 and supported on the support plate 234. When the discharge port sealing plate 205 is pulled outward, the second mesh plate 232 is supported on the support plate 234 under the action of the mesh plate spring 233. In order to ensure that the discharge port sealing plate 205 keeps sealing the discharge port 218 before the valve fittings are taken out, bolts can be provided on the discharge port sealing plate 205, and the discharge port sealing plate 205 is fixed to the bottom enclosure 210 with bolts.

[0045] The filter screen plate 206 is fixed inside the bottom enclosure 210 and is located below the receiving screen plate 204. The filter screen plate 206 is provided with mesh holes for the cleaning liquid to pass through and for intercepting debris. There is a gap between the rear end of the filter screen plate 206 and the rear inner wall of the bottom enclosure 210.

[0046] The scraper 207 is slidably assembled in the bottom enclosure 210 along the front-back direction. Specifically, square pins 235 are fixedly installed at both ends of the scraper 207. The square pins 235 pass through the pin through-holes 217 and fit into the inclined grooves 212 of the top enclosure 209, so that the scraper 207 can only slide along the front-back direction and will not rotate. The bottom of the scraper 207 contacts the top surface of the filter screen 206, or there is only a small gap between them, so that when the scraper 207 moves backward, it can scrape off the debris on the filter screen 206.

[0047] The debris box 208 is installed in the debris discharge port 219 by being pulled out, and the scraper 207 can scrape the debris on the filter screen plate 206 into the debris box 208, and the debris box 208 can collect the debris.

[0048] In the present invention, the outer cylinder 201 and the discharge port sealing plate 205 together form a closed installation space, the top of the installation space extends to the top surface of the limit block 202, specifically the bottom hole edge of the oil hole 211; the bottom of the installation space extends to the bottom of the receiving mesh plate 204, specifically the bottom of the discharge port sealing plate 205. The top opening of the installation space is a channel between the two limit blocks 202.

[0049] The function of the driving mechanism 300 is to drive the inner bearing cylinder 203 to rotate. When the closed section 225 of the inner bearing cylinder 203 is at the bottom, the valve parts to be cleaned can be placed between two adjacent supporting mesh plates and between the third supporting mesh plate 229 and the mesh section 226. At this time, the inner bearing cylinder 203 is in the discharge position, such as Fig.14 When each supporting mesh plate is in a horizontal state, the valve parts are laid flat on each supporting mesh plate, and the cleaning liquid cleans the valve parts. At this time, the inner bearing cylinder 203 is in the cleaning position, as shown in FIG. Fig.15 When the closed section 225 of the inner bearing tube 203 is at the top, the closed section 225 seals the passage between the two limit blocks 202, closing the top opening of the installation space. At this time, the inner bearing tube 203 is in the closed position, as shown in FIG. Fig.16 shown.

[0050] like Figures 1 to 5 as well as Figures 19 to 22 As shown, the driving mechanism 300 includes a sliding seat, a handle 304, a tightening bolt 305, a first rack 306, a second rack 307, and a gear 308. The sliding seat is slidably assembled on the housing 101 along the front-back direction. Specifically, the sliding seat includes a vertical plate 301 and a horizontal plate 302 fixed on the top of the vertical plate 301. The vertical plate 301 is located in the receiving groove 105 of the housing 101. The horizontal plate 302 passes through the guide hole 106 of the housing 101 and can move left and right in the guide hole 106. A groove 303 is provided on the side of the vertical plate 301 facing the carrier module 200. A first rack 306 is provided on one side of the groove wall of the groove 303, and a second rack 307 is provided on the other side of the groove wall. The first rack 306 is located above the second rack 307.

[0051] The handle 304 is fixed on the horizontal plate 302 and is located outside the housing 101. The handle 304 is a plate body. There are two tightening bolts 305, which are threadedly assembled on both sides of the handle 304. After the sliding seat moves into position, the tightening bolts 305 are rotated to press against the outer surface of the housing 101, thereby fixing the position of the sliding seat.

[0052] There are two gears 308 , which are fixed on the rotating shaft 224 respectively. The gears 308 are located outside the outer cylinder 201 .

[0053] Usage process: In the initial state, the inner bearing cylinder 203 is in the discharge position, and the sliding seat is moved toward the side where the second rack 307 is located. At this time, the sliding seat is in the first position, such as Fig.21 As shown, the valve fittings are placed into the inner carrier cylinder 203 .

[0054] The bearing module 200 is lowered into the ultrasonic cleaning machine 100. During the lowering process, the gear 308 meshes with the first rack 306, and the inner bearing cylinder 203 rotates while being lowered. After being lowered into place, each supporting mesh plate is arranged horizontally, and the valve accessories are laid flat on the supporting mesh plates (it should be noted that if the supporting mesh plates are not arranged horizontally after being lowered into place, the inner bearing cylinder 203 can be manually rotated for leveling). Then the ultrasonic cleaning machine 100 starts to work and cleans the valve accessories.

[0055] After cleaning is completed, the sliding seat is moved toward the side where the first rack 306 is located. At this time, the sliding seat is in the second position. Fig. 22 As shown, the bearing module 200 is lifted up. Before the bearing module 200 reaches the cleaning liquid surface, the gear 308 meshes with the first rack 306, so that the inner bearing cylinder 203 rotates to the closed position, and the closed section 225 and the limit block 202 together close the top of the bearing module 200. At this time, the valve accessories fall on the material receiving mesh plate 204, and the debris falls on the filter mesh plate 206 after passing through the material receiving mesh plate 204. The bottom frame 210 slides downward under the action of gravity. During the sliding process, the square pin 235 slides in the inclined groove 212, driving the scraper 207 to slide, and scraping the debris on the filter mesh plate 206 into the debris box 208.

[0056] During the process of lifting the carrying module 200, the top of the carrying module 200 is closed, and the outer cylinder 201 and the discharge port sealing plate 205 together form an installation space that is closed on the top and around. The valve accessories are in the installation space, and oil stains will not cause secondary pollution to the valve accessories.

[0057] In the process of lifting the carrying module 200 , the oil on the outer side of the top of the inner carrying cylinder 203 and the limiting block 202 is carried upward, and is discharged to the outside of the housing 101 after passing through the oil through hole 211 and the drain port 103 .

[0058] In this embodiment, the outer cylinder 201 includes a top frame 209 and a bottom frame 210. The bottom frame 210 is floatingly assembled in the top frame 209. The scraper 207 is driven to move by the cooperation of the inclined groove 212 and the square pin 235. In other embodiments, the outer cylinder 201 is an integrated structure, and the scraper 207 can be driven to slide manually.

[0059] In this embodiment, there are two gears 308. No matter how the carrier module 200 is placed, there is always a gear 308 that meshes with the first rack 306 and the second rack 307. In other embodiments, only one gear 308 may be provided. In this case, when the carrier module 200 is lowered, it is necessary to ensure that the side where the gear 308 is located corresponds to the side where the first rack 306 and the second rack 307 are located.

[0060] In this embodiment, the driving mechanism 300 includes a first rack 306, a second rack 307 and a gear 308, which drive the inner bearing tube 203 to rotate by meshing. In other embodiments, the inner bearing tube 203 can be rotated manually.

[0061] In this embodiment, there are five supporting mesh plates. In other embodiments, the number of supporting mesh plates can be increased or decreased according to actual conditions, or there can be only one supporting mesh plate.

[0062] In addition, in the description of this specification, “plurality” means at least two, for example, two, three or more, etc., unless otherwise clearly and specifically defined.
