Description

Technical Field

[0001] This utility model relates to the field of gas cylinder inspection technology, and in particular to a filtration device for gas cylinder inspection. Background Technology

[0002] A gas cylinder is a sealed metal or non-metal container with a volume not exceeding 1000 liters used for storing and transporting permanent gases, liquefied gases, dissolved gases, or adsorbed gases. Regular inspection of gas cylinders is crucial for ensuring their safe use and extending their service life. Before testing, the cylinder's interior needs to be flushed to ensure the accuracy of the test results. Because gas cylinders accumulate rust, welding slag, and other solid particles over long-term use, the flushing solution must be filtered to prevent blockage of drain pipes or damage to pressure reducing valves and other equipment.

[0003] According to the search, the Chinese patent "A Filtering Device in Gas Cylinder Inspection" (authorization announcement number CN217111038U) works by filling the gas cylinder with water, causing impurities in the cylinder to overflow with the water. When the water is discharged, the impurities are adsorbed on a precision filter screen, preventing blockage of the drain pipe. This method has a high degree of automation and improves processing efficiency.

[0004] While the precision filter used in the above application can intercept and filter impurities, the accumulation of impurities on the precision filter during the filtration process can easily cause blockage, affecting the drainage efficiency during the filtration process. Utility Model Content

[0005] Therefore, it is necessary to provide a filtration device for gas cylinder inspection to address the problem that impurities accumulating on the precision filter screen during the filtration process can easily cause clogging and affect the drainage efficiency during the filtration process.

[0006] The device includes: a processing box; a filtration mechanism, the filtration mechanism including a filter plate fixedly connected to the inner wall of the processing box, the filter plate being inclined, a chip collection frame slidably connected to one end of the inner wall of the processing box, a movable plate slidably connected to one side of the inner wall of the processing box, a magnetic roller and a collection frame rotatably connected to one side of the movable plate, the top end of the collection frame being in contact with the surface of the magnetic roller, a scraper fixedly connected to one side of the movable plate, the bottom end of the scraper being in contact with the top end of the filter plate, a rack fixedly connected to one side of the processing box, one end of the rotating shaft of the magnetic roller passing through the movable plate and fixedly connected to a gear meshing with the rack, and a drive assembly provided on one side of the processing box.

[0007] In one embodiment, the drive assembly includes a motor fixedly connected to one side of the processing box. A lead screw is fixedly connected to the output shaft of the motor, and a slider is threaded onto the surface of the lead screw. The top end of the slider is fixedly connected to the bottom end of the moving plate. This facilitates driving the moving plate to move the scraper, suction roller, and collection frame along the top of the filter plate.

[0008] In one embodiment, a coil spring is fixedly connected to the inner wall of the movable plate, and the other end of the coil spring is fixedly connected to the surface of the rotating shaft of the collection frame, which helps to ensure the stability of the collection frame during the operation of the device.

[0009] In one embodiment, a limiting rod is fixedly connected to one side of the movable plate, and one side of the limiting rod is in contact with one side of the collection frame. This helps to ensure that the collection frame remains stable during the rotation of the magnetic roller and prevents the collection frame from tilting in the direction of the magnetic roller when it rotates.

[0010] In one embodiment, a guide plate is fixedly connected to the other end of the inner wall of the treatment tank. The guide plate is inclined, with its lower end positioned above the higher end of the filter plate to prevent the aqueous solution from entering the collection frame during the filtration process.

[0011] In one embodiment, the debris collection frame is positioned below the lower end of the filter plate. This facilitates better collection of impurities that accumulate after cleaning.

[0012] In one embodiment, the scraper has an isosceles triangle vertical cross-section, and the horizontal height of the bottom of the scraper is higher than the horizontal height of the lowest point of the lower end of the magnetic roller surface. This reduces the friction between the scraper and the filter plate during the cleaning process.

[0013] In one embodiment, one end of the rotating shaft of the collection frame extends through the moving plate and is fixedly connected to a knob, the surface of which is fixedly connected with multiple protrusions. This facilitates better operation by the operator to drive the collection frame to rotate.

[0014] Beneficial effects

[0015] 1. The above-mentioned filtration mechanism uses a filter plate to filter the aqueous solution used for rinsing the gas cylinder. After filtration, the driving component causes the moving plate to move the scraper and the magnetic roller along the top of the filter plate. This allows the magnetic roller to adsorb and clean the iron filings and other easily adsorbed impurities intercepted at the top of the filter plate. The scraper then scrapes and cleans the remaining impurities on the filter plate after they have been adsorbed, ensuring the cleaning effect of the impurities intercepted on the filter plate. The cleaned impurities are collected by a collection frame, which facilitates better centralized cleaning of the filtered impurities. Furthermore, the interaction between the gear and rack causes the magnetic roller to rotate synchronously during movement. The collection frame helps to simultaneously scrape and clean the iron filings adsorbed on the surface of the magnetic roller, thereby improving the cleaning effect of the magnetic roller on easily adsorbed impurities such as iron filings. Through the interaction of the scraper, the magnetic roller, and the collection frame, it is beneficial to avoid the accumulation of impurities on the filter plate and prevent blockage, thus ensuring the drainage efficiency during the filtration of the rinsing aqueous solution.

[0016] 2. By setting a coil spring and a limiting rod, the stability of the collection frame during the operation of the device can be guaranteed, and the collection frame can be restored to its initial state when the force is released after rotating the collection frame.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The following is combined Figure 1 - Figure 5 This invention describes a filtration device used in the inspection of gas cylinders.

[0027] In one embodiment, a filtration device for gas cylinder inspection includes: a processing box 100;

[0028] The filtration mechanism 200 includes a filter plate 210 fixedly connected to the inner wall of the processing box 100. The filter plate 210 is inclined. A chip collection frame 220 is slidably connected to one end of the inner wall of the processing box 100. A movable plate 230 is slidably connected to one side of the inner wall of the processing box 100. A magnetic roller 240 and a collection frame 260 are rotatably connected to one side of the movable plate 230. The top end of the collection frame 260 is in contact with the surface of the magnetic roller 240. A scraper 250 is fixedly connected to one side of the movable plate 230. The bottom end of the scraper 250 is in contact with the top end of the filter plate 210. A rack 280 is fixedly connected to one side of the processing box 100. One end of the rotating shaft of the magnetic roller 240 passes through the movable plate 230 and is fixedly connected to a gear 270 that meshes with the rack 280. A drive assembly 290 is provided on one side of the processing box 100.

[0029] It should be noted that the lowest point of the lower end of the surface of the magnetic roller 240 is only a certain distance away from the top of the filter plate 210. A groove matching the moving plate 230 is opened on one side of the inner wall of the treatment box 100, and the inclination angle of the groove is the same as that of the filter plate 210. Therefore, when the moving plate 230 moves along the path of the groove, the bottom end of the scraper 250 is always in contact with the top of the filter plate 210, and the lowest point of the lower end of the surface of the magnetic roller 240 and the top of the filter plate 210 always maintain the same distance. Protective covers are fixedly connected to both sides of the moving plate 230. The two ends of the two protective covers are fixedly connected to the inner walls of the groove respectively. The protective covers are rubber components. When the moving plate 230 moves, it will drive the corresponding protective cover to extend and retract, so that the protective cover protects the groove and prevents the aqueous solution from overflowing from the groove.

[0030] During the inspection of the gas cylinder, when rinsing the inside of the gas cylinder, water is injected into the inside of the cylinder using a high-pressure water gun. After the water is injected, it is drained. When draining the aqueous solution, the aqueous solution inside the gas cylinder is poured from the higher end of the filter plate 210 into the treatment box 100.

[0031] A drain pipe is connected to the lower end of the treatment box 100 away from the chip collection frame 220. A valve is installed on the surface of the drain pipe. When using this device to filter the rinsing water, the valve is opened and the filtered aqueous solution is discharged through the drain pipe.

[0032] In this embodiment, the tilt angle of the rack 280 is the same as that of the filter plate 210 and the slide groove. Therefore, when the moving plate 230 moves in the slide groove, the gear 270 always meshes with the rack 280.

[0033] When the moving plate 230 drives the magnetic roller 240 to move from the higher end of the filter plate 210 to the lower end of the filter plate 210, the magnetic roller 240 will rotate clockwise under the action of the gear 270 and the rack 280. (See reference...) Figure 4 .

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, the drive assembly 290 includes a motor 291 fixedly connected to one side of the processing box 100. The output shaft of the motor 291 is fixedly connected to a lead screw 292. A slider 293 is threadedly connected to the surface of the lead screw 292. The top end of the slider 293 is fixedly connected to the bottom end of the moving plate 230.

[0035] In this embodiment, the tilt angle of the lead screw 292 is the same as the tilt angle of the filter plate 210. When the motor 291 is started by the controller, the output shaft of the motor 291 drives the lead screw 292 to rotate, which in turn drives the slider 293 to move the moving plate 230 along the slide groove.

[0036] Two fixed blocks are fixedly connected to one side of the processing box 100. The inner walls of the two fixed blocks are rotatably connected to the surface of the lead screw 292. Protective sleeves are fixedly connected to the opposite ends of the two fixed blocks. The other ends of the two protective sleeves are fixedly connected to the two ends of the slider 293 respectively. The surface of the lead screw 292 is located inside the protective cover. The protective cover is a rubber component. When the slider 293 moves, it will drive the corresponding protective cover to extend and retract, thereby protecting the lead screw 292.

[0037] like Figure 5 As shown, a coil spring 231 is fixedly connected to the inner wall of the movable plate 230, and the other end of the coil spring 231 is fixedly connected to the surface of the rotating shaft of the collection frame 260.

[0038] In this embodiment, both sides of the collection frame 260 are inclined. In the initial state, the coil spring 231 is in the released state, and the tilt angle of the top of the collection frame 260 is the same as the tilt angle of the filter plate 210.

[0039] like Figure 5 As shown, a limiting rod 232 is fixedly connected to one side of the movable plate 230, and one side of the limiting rod 232 is in contact with one side of the collection frame 260.

[0040] In this embodiment, the limiting rod 232 is inclined, and one side of the limiting rod 232 is in contact with the inclined surface of the collecting frame 260 near the magnetic roller 240, so as to prevent the device from tilting towards the magnetic roller 240 during operation.

[0041] like Figure 2 As shown, a guide plate 110 is fixedly connected to the other end of the inner wall of the treatment box 100. The guide plate 110 is inclined and the lower end of the guide plate 110 is located above the higher end of the filter plate 210.

[0042] In this embodiment, there is a certain distance between the lower end of the guide plate 110 and the higher end of the filter plate 210. In the initial state, the scraper 250, the magnetic roller 240 and the collection frame 260 are all located below the guide plate 110, and there is a certain distance between the scraper 250 and the end of the filter plate 210 near the scraper 250, so as to ensure that the protective cover has a certain compression space, and at the same time, to prevent the aqueous solution from entering the collection frame 260.

[0043] like Figure 2 As shown, the chip collection frame 220 is located below the lower end of the filter plate 210.

[0044] In this embodiment, the bottom of the chip collection frame 220 is provided with multiple through holes, through which the aqueous solution entering the chip collection frame 220 can be discharged. The diameter of the through holes is smaller than the mesh diameter of the filter plate 210. The chip collection frame 220 can be inserted into the treatment box 100 through one end, and the chip collection frame 220 can be fixed to the treatment box 100 with bolts. The scraper 250, the magnetic roller 240 and the collecting frame 260 do not affect the chip collection frame 220 during the movement of the scraper 250, the magnetic roller 240 and the collecting frame 260 towards the chip collection frame 220.

[0045] like Figure 5 As shown, the vertical cross-section of the scraper 250 is an isosceles triangle, and the horizontal height of the bottom of the scraper 250 is higher than the horizontal height of the lowest point of the lower end of the surface of the magnetic roller 240. This ensures the effective cleaning of impurities on the filter plate 210 by the scraper 250.

[0046] like Figure 5 As shown, one end of the rotating shaft of the collection frame 260 passes through the moving plate 230 and is fixedly connected to a knob 233. Multiple protrusions are fixedly connected to the surface of the knob 233. These protrusions are rubber components. When the collection frame 260 moves above the chip collection frame 220, the operator can rotate the knob 233 clockwise to rotate the collection frame 260 clockwise, causing the coil spring 231 to contract, thus allowing the debris inside the collection frame 260 to fall into the chip collection frame 220.

[0047] Working principle: When the rinsing solution from the gas cylinder is poured into the treatment tank 100 from the higher end of the filter plate 210, the filter plate 210 filters out impurities such as iron filings in the solution. The impurities are retained on the filter plate 210, and the filtered solution is discharged through the drain pipe. After the rinsing solution is filtered, the controller starts the drive assembly 290, which drives the moving plate 230 to move the scraper 250, the magnetic roller 240, and the collection frame 260 towards the lower end of the filter plate 210. During the movement, the magnetic roller 240 adsorbs and cleans the impurities such as iron filings retained on the filter plate 210. The scraper 250 scrapes and cleans the remaining impurities on the filter plate 210 after they have been adsorbed. During the movement, the magnetic roller 240 is driven by the gear 270 and the rack 28. The device rotates clockwise. During this rotation, the top side of the collection frame 260 scrapes and cleans the iron filings adsorbed on the surface of the magnetic roller 240. When the large scraper 250 moves above the chip collection frame 220, the drive assembly 290 is turned off. At this time, the impurities scraped by the scraper 250 fall into the chip collection frame 220. The operator drives the collection frame 260 to rotate by the knob 233, causing the iron filings in the collection frame 260 to fall into the chip collection frame 220 for collection. This completes the cleaning of the impurities retained on the filter plate 210. After cleaning, the output shaft of the start motor 291 drives the lead screw 292 to rotate in the opposite direction, thereby driving the moving plate 230 to restore the scraper 250, magnetic roller 240 and collection frame 260 to their initial state. The chip collection frame 220 can be disassembled and cleaned periodically.

[0048] It should be noted that the motor 291 and other components mentioned above are all devices with relatively mature existing technologies. The specific model can be selected according to actual needs. In addition, the motor 291 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0049] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
