Description

Technical Field

[0001] This utility model relates to the technical field of cast iron pot production equipment, and in particular to a spraying equipment for applying anti-rust coating to cast iron pots. Background Technology

[0002] Cast iron cookware refers to cooking utensils made primarily of cast iron through a casting process. Its main component is cast iron, and alloying elements such as silicon and manganese may be added to improve its performance. Typical casting methods include sand casting and metal mold casting. These multi-functional cookwares feature uniform heat conduction, strong heat storage capacity, and uncoated health benefits. Their core value lies in balancing functionality and durability, making them a classic choice for "one pot for multiple uses" in both home and commercial kitchens.

[0003] The working principle of the anti-rust coating spraying equipment for cast iron pot production: The pressurizing device pressurizes the anti-rust liquid in the storage tank to the set pressure, and then delivers it to the spray gun through the pipeline. The anti-rust liquid is dispersed into tiny particles by the atomizing device in the spray gun, and then accelerated by compressed air and sprayed onto the surface of the cast iron pot to form a uniform coating. The scattered anti-rust liquid is recovered through the collection hopper. The filter screen in the collection hopper filters the anti-rust liquid and then flows back into the storage tank, realizing a closed loop circulation and reducing material consumption.

[0004] However, in the existing rust-preventive coating spraying equipment used in cast iron pot production, although the scattered rust-preventive liquid is collected in the collection hopper for purification and reuse, the filter screen in the collection hopper is usually fixed with screws, which makes it inconvenient to clean and replace the filter screen.

[0005] Therefore, this utility model proposes a spraying equipment for applying anti-rust coating to cast iron pots to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a spraying equipment for applying anti-rust coating to cast iron pots, so as to solve the problems mentioned in the background art.

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a spraying device for applying an anti-rust coating to cast iron pots, comprising a workbench 1, a mounting frame 2 fixedly connected to the upper surface of the workbench 1, a telescopic cylinder fixedly connected to the top of the mounting frame 2, an electromagnetic fixing block 3 fixedly connected to the output end of the telescopic cylinder, a groove formed on the lower surface of the electromagnetic fixing block 3, and an electromagnet fixedly connected in the groove for fixing the cast iron pot. The electromagnet is prior art and will not be described in detail. A liquid storage tank 8 is fixedly connected to the lower surface of the workbench 1 for storing anti-rust liquid. A fixing bracket is fixedly connected to the upper surface of the workbench 1, and an atomizing nozzle 5 is fixedly connected to the upper surface of the fixing bracket for atomizing and spraying the anti-rust liquid. The rust-preventive liquid is applied to the surface of a cast iron pot. A negative pressure filter assembly 6 is fixedly connected to the upper surface of the workbench 1 to recover and filter any spilled rust-preventive liquid. A booster pump 7 is fixedly connected to the upper surface of the storage tank 8. The input end of the booster pump 7 extends into the storage tank 8, and the output end of the booster pump 7 is connected to a delivery pipe. The end of the delivery pipe away from the booster pump 7 is connected to the inlet end of the atomizing nozzle 5. The booster pump delivers the rust-preventive liquid in the storage tank to the atomizing nozzle. The bottom of the negative pressure filter assembly 6 is connected to the upper surface of the storage tank 8. A negative pressure pump 4 is fixedly connected to the outer surface of the storage tank 8. The negative pressure pump 4 draws air from the top of the storage tank 8 to create a negative pressure, allowing the spilled rust-preventive liquid to be recovered by the negative pressure filter assembly 6.

[0024] In actual use, the bottom of the cast iron pot is fixed by the electromagnet in the groove on the lower surface of the electromagnetic fixing block 3. The telescopic cylinder is activated, and the output end of the telescopic cylinder moves the cast iron pot down to above the atomizing nozzle 5. The booster pump 7 is activated, and the input end of the booster pump 7 delivers the rust-preventive liquid in the storage tank 8 through the delivery pipe and sprays it onto the surface of the cast iron pot through the atomizing nozzle 5. At the same time, the negative pressure pump 4 draws air from the top of the storage tank 8 to form a negative pressure. The excess rust-preventive liquid is filtered by the negative pressure filter assembly 6 and then recycled back to the storage tank 8 for reuse.

[0025] The negative pressure filtration assembly 6 includes a negative pressure collection hopper 61 fixedly connected to the upper surface of the workbench 1. The bottom of the negative pressure collection hopper 61 is connected to the upper surface of the liquid storage tank 8. A mounting plate 65 is fixedly connected to the inner wall of the negative pressure collection hopper 61. A threaded groove 66 is formed through the upper surface of the mounting plate 65. A threaded rod 68 is threadedly connected to the inner wall of the threaded groove 66. A knob 67 is fixedly connected to the end of the threaded rod 68 away from the threaded groove 66. Several protrusions arranged in a circular array are fixedly connected to the outer surface of the knob 67 to facilitate the operator to rotate the threaded rod 68. A mounting frame 62 is slidably connected to the inner wall of the collecting hopper 61. A handle 63 is fixedly connected to the upper surface of the mounting frame 62 to facilitate the removal of the mounting frame 62. Several fixed through slots are provided through the upper surface of the mounting frame 62 to facilitate the passage of threaded rods 68. A pull-out groove 610 is provided through the outer wall of the mounting frame 62. A fixed groove 611 is provided on the inner wall of the mounting frame 62. A pull-out plate 69 is slidably connected in the pull-out groove 610. A filter plate 64 is fixedly connected to the side of the pull-out plate 69 away from the pull-out groove 610. The filter plate 64 is used to filter the recovered rust-preventive liquid.

[0026] In actual use, when the filter plate 64 needs to be cleaned or replaced, the operator holds the protrusion and rotates the knob 67 to drive the threaded rod 68 to rotate, unscrewing it from the threaded groove 66 on the mounting plate 65, thus releasing the fixing of the mounting frame 62. The mounting frame 62 is then pulled out from the negative pressure collection hopper 61 by the handle 63. The filter plate 64 is then pulled out from the fixing groove 611 and the pull groove 610 by pulling the pull plate 69. The filter plate 64 is then cleaned and replaced by inserting it into the fixing groove 611 and the pull groove 610 by pulling the pull plate 69. Then, the mounting frame 62 is inserted into the negative pressure collection hopper 61. The threaded rod 68 is passed through the fixing through groove on the mounting frame 62 and tightened to complete the installation of the cleaned and replaced filter plate 64.
