Description

Technical Field

[0001] The present invention relates to the field of rust inhibitor detection, especially the detection equipment used in the production process of rust inhibitors. Background Art

[0002] A rust inhibitor is a chemical preparation used to prevent metal surfaces from rusting. The film-forming substances in the rust inhibitor will form a dense protective film on the metal surface, isolating the metal from air, moisture and other corrosive media, thus preventing substances such as oxygen and water from reacting with the metal chemically, achieving the purpose of rust prevention. Some rust inhibitors contain corrosion inhibitor components, which can inhibit the anodic dissolution or cathodic hydrogen evolution process of the metal by adsorbing on the metal surface, changing the charge distribution on the metal surface or forming an insoluble protective film, and slowing down the corrosion rate of the metal.

[0003] During the production process of rust inhibitors, as well as for the finished rust inhibitor products obtained, detection is required. Detecting intermediate products can monitor the reaction process and judge whether the reaction proceeds as expected. For example, detecting parameters such as acidity, temperature, reaction time, etc. during the reaction process helps to promptly discover abnormal reactions, take corresponding measures for adjustment, and ensure the quality stability of the final product. Conducting a comprehensive inspection of the produced rust inhibitor products, including detecting their rust prevention performance, viscosity, flash point, stability and other indicators, ensures that the products meet relevant national standards, industry standards or enterprise internal standards. Only products that pass the inspection can be put on the market, thus guaranteeing the product quality.

[0004] In the existing full production process of rust inhibitors, they generally flow through multiple storage tanks. Currently, the detection of rust inhibitors is carried out by manually sampling from such storage tanks. To achieve the detection of various intermediate products or products in the production of rust inhibitors, such a manual sampling method is not only inefficient, but also may contaminate the intermediate products or finished products due to manual operations.

[0005] Although there are existing automated detection devices, they basically sample the products in the storage tanks of each process through relatively long pipelines. In this way, there will be a large amount of residue in the pipelines, resulting in a greater impact on the next sampling and detection by the residue, reducing the detection accuracy. Moreover, the existing sampling is point sampling, with a low coverage area, resulting in poor sampling uniformity. Therefore, a detection device for the production process of rust inhibitors is proposed. Summary of the Invention

[0006] In order to overcome the deficiencies of the prior art, the present invention proposes a detection device for the production process of rust inhibitors, which can effectively protect the charging gun and charging cable on the charging pile, and at the same time, the length of the charging cable can be flexibly adjusted to be able to use the charging pile for charging more flexibly.

[0007] To solve the above technical problems, the basic technical solution proposed by the present invention is as follows:

[0008] An inspection device for the production process of an anti-rust agent, comprising a base and a storage tank. A motor is installed in the storage tank, and the output end of the motor is connected to a lead screw. A sleeve that slides up and down in the storage tank is sleeved on the lead screw. A ring frame is slidably sleeved on the outside of the sleeve. A plurality of sliding seats are slidably connected to the ring frame in a radial array. A first spring is also connected between the sliding seat and the inner wall of the ring frame. One end of each sliding seat close to each other is connected with a clamping block, and a plurality of clamping slots for inserting the clamping blocks are arrayed on the outside of the sleeve.

[0009] A rotating plate is rotatably connected in the ring frame, and a sampling suction nozzle is installed at one end of the rotating plate close to the center of the ring frame. A first rotating rod is also rotatably connected between the rotating plate and the sliding seat on each side. A driving component is arranged in the storage tank. The driving component is used to drive each sliding seat to slide close to or away from each other, so as to combine the sleeve and the ring frame when sliding close to each other, and pull the rotating plate to rotate from the folded state to the unfolded state. A separating component is also arranged on the ring frame. The separating component is used to separate the sleeve and the ring frame when each sliding seat moves away from each other.

[0010] Preferably, a mounting seat sleeved on the outside of the motor is connected inside the storage tank. A first guide rod located outside the lead screw is arrayed and connected on the mounting seat. The sleeve is slidably sleeved on the outside of each first guide rod.

[0011] Preferably, a plurality of sliding grooves are arrayed and connected to the ring frame. The sliding seat is slidably connected in the sliding groove on each side.

[0012] Preferably, second guide rods connected to the inner wall of the ring frame are arranged on both sides of each sliding groove. The two sides of the sliding seat are connected with sleeve plates slidably sleeved on the outside of the second guide rods. The two ends of the first spring are respectively connected to the sleeve plate and the inner wall of the ring frame, and are sleeved on the outside of the second guide rod.

[0013] Preferably, a rotating shaft corresponding to each sliding seat is installed on the ring frame. The rotating plate is installed on the rotating shaft. A groove is formed at one end of each sliding seat close to the rotating plate. The end of the first rotating rod away from the rotating plate is rotatably connected to the inner wall of the groove, and the rotating plate is rotatably arranged in the groove.

[0014] Preferably, the driving component includes a lower clamping seat, a fourth guide rod, an upper clamping seat, a telescopic member, and a ring seat. The lower clamping seat is connected to the upper end of the sliding seat. The fourth guide rod is arranged along the sliding direction of the sliding seat and is connected to the inner wall of the storage tank. The upper clamping seat is slidably sleeved on the outer side of the fourth guide rod and is cooperatively sleeved with the lower clamping seat. The telescopic member is installed on the inner wall of the storage tank. The ring seat is connected to the output end on the lower side of the telescopic member. A second rotating rod is rotatably connected between the ring seat and each sliding seat.

[0015] Preferably, the separation assembly includes a third guide rod, collar, rubber ring, and top plate. The third guide rod is connected to the outside of the ring frame. Two collars are provided, one above the other, and are slidably sleeved on the upper and lower sides of the third guide rod. A second spring sleeved on the third guide rod is connected between the collars on the upper and lower sides. The rubber ring is connected between the collars on the upper and lower sides. An inclined block corresponding to each slide seat is connected to the upper collar. The top plate is connected to the slide seat and slidably fits and abuts against the inclined surface of each inclined block.

[0016] Preferably, both the collar and the rubber ring are slidably sleeved on the outside of the ring frame.

[0017] Preferably, a sampling pump is installed on the storage tank, and the sampling pump is connected to each sampling nozzle through a hose. The upper end of the storage tank is provided with a feed inlet, and a discharge valve is installed at the lower end.

[0018] Preferably, a bracket is installed on the inner wall of the storage tank. The lower end of the lead screw is rotatably connected to the bracket. A plurality of stirring rods are also rotatably connected to the bracket in an array. A gear is sleeved on the lower end of each stirring rod. A gear ring meshing with the gear is sleeved on the lower end of the lead screw.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The technical solution of the present invention controls each slide seat to approach each other under the action of the first spring through the driving assembly, so as to realize the insertion connection of the slide seat and the sleeve through the cooperation of the block and the slot. In this way, when the motor drives the lead screw to rotate forward and backward reciprocally, it can drive the slide seat and the ring frame to slide up and down reciprocally, so that the sampling nozzle can follow and slide up and down to sample the liquid agent at different depths in the storage tank, increasing the uniformity of sampling. At the same time, the mutual approach of each slide seat can also pull the rotating plate to rotate through the first rotating rod, and expand each sampling nozzle that is far away from each other and in a folded state to the middle of the storage tank, further improving the uniformity of sampling;

[0021] 2. The technical solution of the present invention can separate the block from the slot by pushing each slide seat to move away from each other through the driving assembly, and then separate the ring frame from the sleeve. At the same time, during this process, the top plate will push each inclined block to slide, driving the collars on the upper and lower sides to approach each other, compressing the rubber ring, so that the rubber ring can bulge outwards and fit and abut against the inner wall of the storage tank, and the ring frame is stably limited in the storage tank through the friction between the rubber ring and the inner wall of the storage tank for subsequent use. At the same time, in this way, after sampling, the sampling nozzle can be moved above the liquid agent and emptied, avoiding the problem that existing sampling equipment is directly arranged below the liquid level of the liquid agent and cannot be effectively emptied, resulting in easy residue and affecting subsequent sampling, thereby improving the accuracy of sampling detection;

[0022] 3. The technical solution of the present invention drives each stirring rod to rotate through a lead screw, which can stir the liquid agent during sampling, thereby further improving the uniformity of sampling. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the attached Figure 1 to the attachedFigure 10 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1:

[0037] As Figures 1-3 As shown in FIGS. 8-10, the present invention discloses a detection device for the production process of rust inhibitors, including a base 1 and a storage tank 2. A motor 6 is installed in the storage tank 2, and the output end of the motor 6 is connected to a lead screw 7. A sleeve 10 that slides up and down in the storage tank 2 is threadedly sleeved on the lead screw 7. A ring frame 11 is slidably sleeved on the outside of the sleeve 10. A plurality of sliding seats 13 are slidably connected to the ring frame 11 along the radial direction. A first spring 16 is also connected between the sliding seat 13 and the inner wall of the ring frame 11. One end of each sliding seat 13 close to each other is connected to a clamping block 22. A plurality of card slots 23 that are matched and inserted with the clamping block 22 are arrayed on the outside of the sleeve 10. Among them, the motor 6 is installed on the upper inner wall of the storage tank 2;

[0038] A rotating plate 18 is rotatably connected in the ring frame 11, and a sampling suction nozzle 19 is installed at one end of the rotating plate 18 close to the center of the ring frame 11. A first rotating rod 21 is also rotatably connected between the rotating plate 18 and the sliding seat 13 on each side. A driving assembly is arranged in the storage tank 2, and the driving assembly is used to drive each sliding seat 13 to slide close to or away from each other, so as to combine the sleeve 10 and the ring frame 11 when sliding close to each other, and pull the rotating plate 18 to rotate from the folded state to the unfolded state. A separating assembly is also arranged on the ring frame 11, and the separating assembly is used to separate the sleeve 10 and the ring frame 11 when each sliding seat 13 moves away from each other.

[0039] An installation seat 8 sleeved outside the motor 6 is connected inside the storage tank 2. A first guide rod 9 located outside the lead screw 7 is arrayedly connected to the installation seat 8. The sleeve 10 is slidably sleeved on the outside of each first guide rod 9. At the same time, the installation seat 8 is also installed on the upper inner wall of the storage tank 2. The sliding sleeve of the sleeve 10 and the first guide rod 9 enables the sleeve 10 to slide up and down along the axial directions of the lead screw 7 and the first guide rod 9 respectively when the lead screw 7 is driven by the motor 6 to rotate forward and backward.

[0040] A plurality of sliding grooves 12 are arrayedly connected to the ring frame 11. The sliding seat 13 is slidably connected in the sliding groove 12 on each side. The setting of the sliding groove 12 can make the sliding of the sliding seat 13 in the ring frame 11 more stable.

[0041] On both sides of each chute 12, there are guide rods two 14 connected to the inner wall of the ring frame 11. On both sides of the sliding seat 13, there are sleeve plates 15 slidably sleeved on the outer sides of the guide rods two 14. Both ends of the first spring 16 are respectively connected to the sleeve plate 15 and the inner wall of the ring frame 11, and are sleeved on the outer side of the guide rod two 14. The arrangement of the guide rod two 14 can provide support for the first spring 16 and guide the sliding of the sliding seat 13 at the same time. So that without external force, the first spring 16 will push the sliding seat 13 towards the lead screw 7 and the sleeve 10 located at the center of the ring frame 11. Until the block 22 and the slot 23 are inserted and matched, at this time, the sleeve 10 will be assembled and installed together with the ring frame 11.

[0042] On the ring frame 11, there are rotating shafts 17 corresponding to each sliding seat 13. The rotating plate 18 is installed on the rotating shaft 17. At one end of each sliding seat 13 close to the rotating plate 18, there is a groove 20. One end of the first rotating rod 21 away from the rotating plate 18 is rotatably connected to the inner wall of the groove 20. The rotating plate 18 is rotatably arranged in the groove 20. At this time, due to the insertion and matching of the block 22 and the slot 23, the up and down sliding of the sleeve 10 will drive the ring frame 11 together. When the sliding seat 13 slides towards the sleeve 10, it will also pull the rotating plate 18 to rotate through the first rotating rod 21, thereby driving the sampling nozzle 19 in the folded state to unfold. In this way, the sampling nozzle 19 can slide up and down reciprocally to evenly sample the rust inhibitor intermediate product or finished product (collectively referred to as liquid agent) in the middle of the storage tank 2, avoiding sampling at fixed points, which may cause detection errors due to uneven dispersion of effective substances in the liquid agent, and improving the accuracy of sampling and detection.

[0043] A sampling pump 5 is installed on the storage tank 2, and the sampling pump 5 is connected to each sampling nozzle 19 through a hose. The upper end of the storage tank 2 is provided with a feed inlet 3, and the lower end is installed with a discharge valve 4. The sampling pump 5 is an existing extraction device, which can provide power for the sampling of the sampling nozzle 19.

[0044] A bracket 36 is installed on the inner wall of the storage tank 2. The lower end of the lead screw 7 is rotatably connected to the bracket 36. A plurality of stirring rods 37 are also rotatably connected to the bracket 36 in an array. A gear 39 is sleeved on the lower end of each stirring rod 37. A gear ring 38 meshing with the gear 39 is sleeved on the lower end of the lead screw 7. When the lead screw 7 is driven to rotate by the motor 6, it can also drive each stirring rod 37 to rotate through the meshing of the gear 39 and the gear ring 38, stirring the liquid agent in the storage tank 2 evenly, further improving the uniformity of sampling and ensuring the accuracy of detection.

[0045] Embodiment Two:

[0046] As Figures 1-6 shown in FIGS. 8 - 10, the present invention discloses a detection device for the production process of rust inhibitors. Compared with Embodiment One, the structure of the driving component is disclosed in this embodiment.

[0047] The driving assembly includes a lower card seat 30, a guide rod four 31, an upper card seat 32, a telescopic member 33, and a ring seat 34. The lower card seat 30 is connected to the upper end of the slide 13, the guide rod four 31 is arranged along the sliding direction of the slide 13, and is connected to the inner wall of the storage tank 2, the upper card seat 32 is slidingly sleeved on the outer side of the guide rod four 31, and cooperates with the lower card seat 30 to form a card sleeve, the telescopic member 33 is installed on the inner wall of the storage tank 2, the ring seat 34 is connected to the output end on the lower side of the telescopic member 33, and a rotating rod two 35 is rotatably connected between the ring seat 34 and each slide 13.

[0048] In this way, the contraction of the telescopic member 33 can drive the ring seat 34 to move upward, and the upper seats 32 can be pulled closer to each other through the rotating rod 2 35. Since the upper seats 32 are close to each other without any limit, the lower seat 30 will follow the slide 13 to move closer to each other under the action of the spring 16, until the connecting block 22 on the slide 13 is fitted into the groove 23 on the outer side of the sleeve 10. When the telescopic member 33 is extended, the ring seat 34 will be driven to move downward. At this time, the upper seats 32 will contact the lower seats 30 to move away from each other and compress the spring. At this time, the slides 13 will move away from each other, driving the block 22 and the groove 23 to separate, thereby realizing the separation of the ring frame 11 and the sleeve 10.

[0049] Embodiment three:

[0050] like Figures 1-10 As shown, the present invention discloses a detection device for the rust inhibitor production process. Compared with the second embodiment, this embodiment discloses the structure of the separation component.

[0051] The separation assembly includes a guide rod three 24, a collar 25, a rubber ring 26, and a top plate 29. The guide rod three 24 is connected to the outside of the ring frame 11. The collar 25 is set in two upper and lower parts and is slidably sleeved on the upper and lower sides of the guide rod three 24. A spring two 27 sleeved on the outside of the guide rod three 24 is connected between the collars 25 on the upper and lower sides. The rubber ring 26 is connected between the collars 25 on the upper and lower sides. The upper collar 25 is connected to an inclined block 28 corresponding to each slide seat 13. The top plate 29 is connected to the slide seat 13 and slidably fits and contacts with the inclined surfaces of each inclined block 28. The collar 25 and the rubber ring 26 are both slidably sleeved on the outside of the ring frame 11.

[0052] When each sliding seat 13 is driven to move away from each other, separating the ring frame 11 from the sleeve 10, the sliding seat 13 will also drive the top plate 29 connected thereto to gradually contact the inclined block 28, drive the collar rings 25 on the upper and lower sides to approach each other, and compress the rubber ring 26, so that the rubber ring 26 can bulge outwards, fit and contact the inner wall of the storage tank 2, and limit the ring frame 11 firmly in the storage tank 2 through the frictional force between the rubber ring 26 and the inner wall of the storage tank 2 for subsequent use. At the same time, after the sampling is completed, the sampling suction nozzle 19 can be moved above the liquid agent and emptied, avoiding the problem that the existing sampling equipment is directly arranged below the liquid level of the liquid agent and cannot be effectively emptied, resulting in easy residue and affecting subsequent sampling, greatly improving the accuracy of sampling detection.

[0053] According to the disclosure and teaching of the above specification, those skilled in the art to which the present invention pertains can also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
