Description

Technical Field

[0001] The present invention relates to the technical field of enamel reaction kettle production, and particularly to an automatic spraying device for enamel reaction kettle production. Background Art

[0002] The development and progress of electronic technology are inseparable from high-purity hydrofluoric acid, and the filling, storage, and transportation of high-purity hydrofluoric acid require professional storage tanks. Enamel storage tanks have high strength and corrosion resistance, and are the best storage containers for industrial-grade hydrofluoric acid.

[0003] In recent years, the spray enameling process has been widely applied to the production of large enamel storage tanks. The method of spray enameling to manufacture enamel storage tanks is to carry out spray enameling processing on the inner wall of the metal storage tank, so that an enamel inner tank is formed inside the metal storage tank, and it is converted into an enamel storage tank, thereby enhancing the corrosion resistance of the storage tank. The glaze slurry is atomized into fine mist under pressure and is sprayed onto the inner wall of the metal storage tank by manual control. After drying, an enamel layer is formed. The adhesion amount and uniformity of spray enameling are very important, which determine the thickness of the dried coating film and the anti-corrosion effect.

[0004] With the progress of technology, there are currently various spraying devices to improve the spraying efficiency and spraying effect. For example, the Chinese invention patent with the publication number CN118407047A discloses a chemical corrosion-resistant storage tank enamel inner tank production system, which relates to the field of spray enameling, including a driving rotating shaft and a spray enameling nozzle. A fixed-distance extension rod is slidably arranged on the side of the driving rotating shaft, and the spray enameling nozzle is slidably arranged on the side of the fixed-distance extension rod, and a recovery component is arranged on one side of the spray enameling nozzle. The driving rotating shaft extends into the storage tank, and the fixed-distance extension rod on the side of the driving rotating shaft is in different extension states in different sections according to the shape of the storage tank, and the spray enameling nozzle is extended to a position at a certain distance from the inner wall of the storage tank for fixed-distance vertical spraying to ensure the best spray enameling adhesion effect.

[0005] However, these existing spraying devices all have a problem, that is, manual operation of the device is required to process the inner wall of the reaction kettle. And the enamel glaze slurry itself contains heavy metal substances such as lead and cadmium, which will cause serious damage to human health under long-term contact. Although usually, workers will operate in a closed processing workshop wearing full-coverage protective clothing, the harm of the enamel glaze slurry still cannot be completely avoided. Therefore, a fully automated spraying device that can completely eliminate manual operation is needed to process the reaction kettle. Summary of the Invention

[0029] The technical solutions in the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] As Figure 1 shown, an automatic spraying device for the production of an enamel reaction tank is proposed in an embodiment of the present invention, which includes a closed spraying box body 1. Inside the spraying box body 1, a transportation track 2, a detection component, an adjustment component 6, and a spraying component are provided. In this embodiment, the spraying box body 1 is a strip-shaped cuboid structure adapted to the reaction tank, including a top surface, two end faces, and two strip-shaped side faces. A sealable door 11 is provided on one end face of the spraying box body 1. In this embodiment, the sealable door 11 is an electric rolling gate, and the width of the sealable door 11 is greater than the width of the track to cooperate with the entry of the reaction tank.

[0031] The transportation track 2 is arranged at the center of the bottom of the spraying box body 1 along the extending direction of the spraying box body 1, and one end of the transportation track 2 passes through the sealable door 11 and extends to the outside. A transport vehicle 3 is also provided on the transportation track 2. The transport vehicle 3 is used to carry the reaction tank and can move along the transportation track 2. In this embodiment, the transportation track 2 adopts a protruding structure similar to a railway track, and the transport vehicle 3 is electrically driven. The surface of the transport vehicle 3 is a horizontal strip-shaped plate structure, and a number of fixing rods 31 are symmetrically arranged at positions corresponding to both sides of the transportation track 2 on its surface. A fixing wheel 32 is provided at the top end of the fixing rod 31. The axial direction of the fixing wheel 32 is parallel to the reaction tank, so that the fixing wheel 32 contacts the outer side surface of the reaction tank through the arc-shaped side surface, and the reaction tank is supported above the transport vehicle 3.

[0032] As Figure 2 shown, the detection component is correspondingly arranged at a position near the sealable door 11 inside the spraying box body 1 to detect the position of the central axis of the reaction tank placed on the transport vehicle 3. Specifically, the detection component includes a horizontal detection mechanism 4 and a vertical detection mechanism 5. The horizontal detection mechanism 4 includes a first slide rail 41 horizontally arranged on the top end surface inside the spraying box body 1. The first slide rail 41 is arranged perpendicular to the extending direction of the transportation track 2. A first slider 42 is cooperatively arranged on the first slide rail 41. A first infrared distance measuring instrument 43 is fixedly installed at the bottom of the first slider 42. The vertical detection mechanism 5 includes a second slide rail 51 vertically arranged on one side surface inside the spraying box body 1. The second slide rail 51 is arranged perpendicular to the extending direction of the transportation track 2. A second slider 52 is cooperatively arranged on the second slide rail 51. A second infrared distance measuring instrument 53 is fixedly installed on one side of the second slider 52 close to the middle of the spraying box body 1. Among them, the first slide rail 41 and the second slide rail 51 can adopt various existing structures such as ball screw guides, synchronous belt guides, and electric guides. In this embodiment, an electric guide structure similar to a moving camera is adopted.

[0033] When the reaction tank follows the transport vehicle 3 into the spray box 1, detection is carried out, wherein the first infrared rangefinder 43 measures the distance while moving along the first slide rail 41, and the second infrared rangefinder 53 measures the distance while moving along the second slide rail 51. Obviously, when the first infrared rangefinder 43 or the second infrared rangefinder 53 does not pass through the reaction tank, it detects the height or width of the spray box 1, and the detection result is a continuous fixed value. When it passes through the position of the reaction tank, the detection distance will shrink rapidly, and in the process of passing through the reaction tank, a continuously changing value from large to small is received. The two vertical endpoints of this continuously changing section correspond to the positions of the first infrared rangefinder 43 or the second infrared rangefinder 53, that is, the horizontal or vertical positions of the two ends of the reaction tank, and the midpoint of the two vertical ends is the position of the central axis of the reaction tank.

[0034] like Figure 3 As shown, the adjustment component 6 is arranged at one end of the spray box 1 away from the sealing door 11, and the spray component includes a support rod 7 and a spray gun 8. The length of the support rod 7 is not less than the axial length of the reaction tank. The support rod 7 is perpendicular to the end door where the sealing door 11 is located and is installed on the adjustment component 6. The position of the support rod 7 in the horizontal and vertical directions can be changed by adjusting the component 6, so that the support rod 7 passes through the central axis of the reaction tank. In this way, the spacing between the spray gun 8 on the support rod 7 and the inner wall of the reaction tank can be controlled to be the same, so as to obtain a more uniform spraying effect.

[0035] like Figure 4As shown, in a specific solution, the adjusting assembly 6 includes a horizontal adjusting mechanism and a vertical adjusting mechanism. The horizontal adjusting mechanism includes two horizontally arranged connecting columns 61. The connecting columns 61 are perpendicular to the end face of the spraying box body 1 corresponding to the adjusting assembly 6, and the connecting columns 61 are located at the two side edges of the corresponding end door. A driving rod 62 and a sliding rod 63 are arranged side by side in the front and back between the connecting columns 61. The driving rod 62 and the sliding rod 63 are horizontally arranged and perpendicular to the connecting columns 61. One end of the support rod 7 is connected to both the driving rod 62 and the sliding rod 63 at the same time, and the support rod 7 is drivingly connected to the driving rod 62 and slidably connected to the sliding rod 63. By the operation of the driving rod 62, the support rod 7 is controlled to move along the direction of the driving rod 62. Preferably, the driving rod 62 is a threaded rod, and a first adjusting block 64 is arranged on the driving rod 62. A roller nut is arranged in the first adjusting block 64, so that a screw connection is adopted between the first adjusting block 64 and the threaded rod. A second adjusting block 65 is arranged on the sliding rod 63, and the second adjusting block 65 is slidably connected to the sliding rod 63. The support rod 7 is fixedly connected to the first adjusting block 64 and the second adjusting block 65 at the same time. One end of the driving rod 62 is also provided with a first motor (not shown). The first motor controls the rotation of the driving rod 62, and then drives the first adjusting block 64 to move through the screw drive. The second adjusting block 65 also moves synchronously during the connection process of the support rod 7, so as to realize the overall movement of the support rod 7. Through the limit of the second adjusting block 65 and the sliding rod 63, the support rod 7 can also be prevented from rotating in other directions.

[0036] Correspondingly, the vertical adjusting mechanism includes two groups of telescopic rods respectively corresponding to the connecting columns 61. Each group of telescopic rods includes a plurality of upper telescopic rods 66 and a plurality of lower telescopic rods 67. The top ends of the upper telescopic rods 66 are fixed to the inner top end face of the spraying box body 1, and the bottom ends are fixedly connected to the connecting columns 61. The bottom ends of the lower telescopic rods 67 are fixed to the inner bottom surface of the spraying box body 1, and the top ends are fixedly connected to the connecting columns 61. The numbers of the upper telescopic rods 66 and the lower telescopic rods 67 correspond to each other. During operation, the two groups of upper telescopic rods 66 and the two groups of lower telescopic rods 67 all operate synchronously. When the upper telescopic rods 66 extend, the lower telescopic rods 67 contract, and vice versa, so as to overall control the movement of the two connecting columns 61 in the vertical direction.

[0037] As Figure 5As shown, in the preferred solution of this embodiment, the connecting part of the support rod 7 and the adjusting component 6 is the connecting section, and the part other than that is the guide rail section. The spray gun 8 is movably installed on the guide rail section. A high-pressure storage tank 9 is further provided outside the spraying box body 1. The high-pressure storage tank 9 is connected to the spray gun 8 through a hose 91. Specifically, the guide rail section includes a control rod 71 and a guide rod 72 arranged in parallel. The control rod 71 is a threaded rod, and the guide rod 72 is a smooth rod. The spray gun 8 is connected to both the control rod 71 and the guide rod 72. The spray gun 8 is connected to the control rod 71 by a screw and is slidably connected to the guide rod 72. A second motor 73 is further provided at the end of the guide rail section corresponding to the adjusting component 6 to drive the control rod 71 to rotate. In this embodiment, the second motor 73 is arranged in parallel outside the guide rail section and can drive the control rod 71 to rotate through a gear set. When the second motor 73 works, it drives the control rod 71 to rotate, and then drives the spray gun 8 to move through a screw drive. The guide rod 72 restricts the orientation of the spray gun 8 so that it can only move along the support rod 7 without rotating, and thus sequentially passes along the axis of the reaction tank at a uniform speed and stability, completing the spraying process on the inner wall of the reaction tank.

[0038] Preferably, the spray gun 8 is movably installed on the support rod 7 and can move along the support rod 7. A plurality of nozzles 83 are provided on the spray gun 8. Further, the spray gun 8 is a cylindrical structure with an axis parallel to the support rod 7. A connecting part 81 is provided in the middle thereof. An annular liquid storage cavity 82 is provided between the connecting part 81 and the arc side surface. The liquid storage cavity 82 is communicated with the hose 91, so that the glaze slurry can be continuously introduced into the spray gun 8 under high pressure through the hose 91 during work to achieve continuous operation. The hose 91 can also be a pressure-resistant corrugated pipe to achieve a certain contraction function and avoid contact with the inner wall of the reaction tank. In this embodiment, six nozzles 83 are arranged at equal intervals in the circumferential direction around the liquid storage cavity 82. In addition, nozzles 83 are also provided on the end surface of the spray gun 8 corresponding to the sealing door 11 to spray the inner bottom surface of the reaction tank.

[0039] In this embodiment, further, an air inlet and an air outlet (not shown) are provided on the spraying box body 1. Both the air inlet and the air outlet are provided with openable and closable hatches. The air outlet is communicated to a waste treatment station through a pipeline with a suction fan. In this way, after spraying is completed, the residual glaze slurry in the spraying box body 1 can be quickly discharged through the suction fan and harmlessly treated through the waste treatment station, avoiding the glaze slurry adhering to the inner wall of the spraying box body 1 or causing damage to various equipment.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
