[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The utility model provides Figure 1-Figure 5 The shown device is an automatic spray pickling and passivation device for a storage tank, comprising a spray bin 1 and a storage tank body 8. The interior of the spray bin 1 is provided with a clamping assembly for fixing the storage tank body 8 and a spray assembly for pickling and passivating the storage tank body 8. The spray assembly comprises a slide fixedly arranged on the top inner wall of the spray bin 1, a first motor 9 is fixedly arranged at the end of the slide, a screw rod 10 is fixedly connected to the rotating shaft end of the first motor 9, a movable block 11 adapted to the slide is threadedly connected at the outer ring of the screw rod 10, a diverter ring 12 is fixedly arranged at the bottom of the movable block 11, a plurality of first nozzles 13 evenly arranged in a ring shape are fixedly arranged at the inner ring of the diverter ring 12, and the diverter ring 12 is movably sleeved on the outside of the storage tank body 8.

[0026] When the first motor 9 is started, the screw rod 10 is driven to rotate, thereby driving the movable block 11 and the diverter ring 12 to move at a set speed inside the spray bin 1, so that the first nozzle 13 sprays the outside of the tank body 8 for pickling and passivation. When the processing is completed, the diverter ring 12 is reset, the clamping assembly releases the tank body 8, and the tank body 8 is taken out of the spray bin 1. Since the tank body 8 of the utility model is placed horizontally during processing, the spray component does not need to be installed at a high place, which solves the problem that when the existing automatic spray pickling and passivation device for tanks sprays the tank body 8 for pickling and passivation, the tank body 8 is generally high and requires a higher spray facility. When the spray facility needs to be repaired, a ladder rack is needed to assist in repairing the spray facility at a high place, which is cumbersome and dangerous to operate.

[0027] Furthermore, a conveying assembly is also provided inside the spray bin 1, and the conveying assembly includes a base plate 2 fixedly provided on the spray bin 1, an electric slide rail 4 fixedly provided on the top of the base plate 2, a base 5 slidingly provided on the electric slide rail 4, a cylinder 6 fixedly provided at the end of the top of the base 5, and a supporting platform 7 fixedly provided at the telescopic end of the cylinder 6, and the upper surface of the supporting platform 7 is an arc-shaped structure. In the initial state, the storage tank body 8 is placed on the supporting platform 7.

[0028] In the initial position, the supporting platform 7 is located outside the spray bin 1. After the storage tank body 8 is placed on the supporting platform 7 by a crane, the base 5, cylinder 6, supporting platform 7 and storage tank body 8 are transported to the designated position inside the spray bin 1 by running the electric slide rail 4. After the clamping assembly clamps the storage tank body 8, the cylinder 6 is started to drive the supporting platform 7 to move downward to prevent it from blocking the movable displacement of the diverter ring 12 outside the storage tank body 8. When the storage tank body 8 is processed, the supporting platform 7 is reset to support the storage tank body 8, and then the storage tank body 8 is pulled out of the spray bin 1. The operation is simple and convenient.

[0029] Furthermore, the clamping assembly includes a chassis 14 fixedly arranged on the inner wall of one side of the spray bin 1, a second motor 15 is fixedly arranged inside the chassis 14, the rotating shaft end of the second motor 15 is fixedly connected to the first electric push rod 16, the telescopic end of the first electric push rod 16 movably extends out of one end of the chassis 14 and is fixedly connected to the first ring 17, and a second ring 18 is rotatably arranged on the inner wall of the other side of the spray bin 1. When the storage tank body 8 is separated from the supporting platform 7, the storage tank body 8 is fixed between the first ring 17 and the second ring 18, and the inside of the first ring 17 and the second ring 18 are fixedly provided with slots, and the inner walls of the slots are fixedly provided with two symmetrically arranged second electric push rods 19, and the telescopic end of the second electric push rod 19 is fixedly connected to the splint 20.

[0030] When the storage tank body 8 is transported to the designated position inside the spray chamber 1, the first electric push rod 16 is started to push the first ring 17 toward the storage tank body 8, and then the other end of the storage tank body 8 is inserted into the slot of the second ring 18. The second electric push rod 19 in the first ring 17 and the second ring 18 is started synchronously, allowing the splint 20 to clamp the two ends of the storage tank body 8, and quickly complete the clamping and fixing of the storage tank body 8.

[0031] In addition, when the vertical cross-sectional diameter of the storage tank body 8 is large, when starting the first motor 9, it is also necessary to start the second motor 15 to rotate the storage tank body 8, and then allow the first nozzle 13 to perform comprehensive spray pickling and passivation on the outside of the storage tank body 8 to avoid dead corners and improve the practicality of the device.

[0032] After the tank body 8 is processed, the splint 20 on the second ring 18 first cancels the clamping of the tank body 8, and the first electric push rod 16 is started to pull the tank body 8 out of the second ring 18. At this time, the splint 20 on the first ring 17 cancels the clamping of the tank body 8, allowing the tank body 8 to fall on the supporting platform 7, making it easier for the supporting platform 7 to pull the tank body 8 out.

[0033] Furthermore, a spray pipe 21 is rotatably provided inside the second sleeve 18, and one end of the spray pipe 21 extending into the slot is fixedly connected to a hemispherical nozzle 22, and a plurality of second nozzles are provided on the hemispherical nozzle 22. The spray pipe 21 and the diverter ring 12 are connected to an external pickling agent source through a hose. After starting the water pump on the external pickling agent source, the pickling agent is sprayed out from the spray pipe 21 and the diverter ring 12 through the hose, and the hemispherical nozzle 22 can perform spray pickling and passivation processing on the inside of the storage tank body 8.

[0034] Taking into account the recycling of the pickling agent, a support rod 3 is fixedly provided at the bottom of the bottom plate 2 extending out of the spray chamber 1. A recovery tank is formed between the bottom plate 2 and the bottom inside the spray chamber 1. A plurality of leakage holes 23 interconnected with the recovery tank are opened on the bottom plate 2. A recovery pipe 24 is provided on the side of the base 5 and is connected to the recovery tank. The recovery pipe 24 is connected to an external pickling agent source. This arrangement facilitates the recycling of the pickling agent and avoids waste of resources.
