[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a dust collection and purification device for thermal spraying equipment, comprising a dust collecting box 1, a dust collecting assembly 2 and an air suction assembly 3. The dust collecting box 1 is provided with a dust collecting assembly 2 at the front side, and an air suction assembly 3 is provided inside the dust collecting box 1. The upper end of the air suction assembly 3 is connected with an exhaust pipe 4. The air suction assembly 3 includes an air suction fan 31. An upper cover plate 12 is installed at the upper end of the dust collecting box 1, and an air suction fan 31 is installed at the lower end of the upper cover plate 12. A filter element 32 is installed at the lower end of the air suction fan 31. The upper end of the upper cover plate 12 is provided with an exhaust pipe 4 through a bolt 5, and the exhaust pipe 4 is communicated with the air suction fan 31.

[0024] During use, the dust box 1 is the main part of the entire dust collection and purification device, which is responsible for accommodating and preliminarily collecting the smoke and waste generated during the thermal spraying process. The dust collecting component 2 preliminarily intercepts and collects the larger particles of smoke and waste generated during the thermal spraying process; the suction fan 31 generates suction to suck the dust-containing gas that has been preliminarily treated by the dust collecting component 2 into the dust box 1, and the filter element 32 further filters the inhaled dust-containing gas to capture tiny particles to achieve deep purification. The upper cover plate 12 enhances the sealing of the dust box 1 to prevent smoke and dust from leaking out; it is convenient for maintenance operations such as installing and replacing the filter element 32, and the exhaust pipe 4 discharges the gas purified by the filter element 32 out of the dust box 1.

[0025] A slide groove 11 is provided at the front end of the dust box 1, and a sliding baffle 21 is movably installed inside the slide groove 11. The design of the sliding baffle 21 allows the front side of the dust box 1 to be easily opened, and the interior of the dust box 1 can be accessed without complicated operations, which is convenient for daily maintenance and deep cleaning.

[0026] The sliding baffle 21 is provided with a strip hole group 211 , which serves as an air inlet passage, allowing smoke and waste gas generated during the thermal spraying process to smoothly enter the dust collecting box 1 without being completely blocked.

[0027] An activated carbon filter plate 22 is arranged at the front end of the dust box 1, and a support frame 23 is arranged on the rear side of the activated carbon filter plate 22. Both sides of the support frame 23 are fixed to the dust box 1 by bolts 5. The activated carbon filter plate 22 uses the strong adsorption property of activated carbon to deeply purify the smoke and waste gas that have been preliminarily treated, effectively remove the tiny particles, harmful gases and odors therein, and ensure that the discharged gas is cleaner; the support frame 23 provides a stable support for the activated carbon filter plate 22, ensuring that it will not be deformed or damaged due to uneven force during operation, thereby ensuring the stability of the purification effect.

[0028] The positions of the activated carbon filter plate 22 and the strip hole group 211 correspond to each other. The activated carbon filter plate 22 directly corresponds to the strip hole group 211, so that the gas entering the dust box 1 can be immediately adsorbed and filtered by the activated carbon.

[0029] The support frame 23 can limit the height and thickness of the activated carbon filter plate 22. The activated carbon filter plate 22 can be taken out by opening the sliding baffle 21. The design of the sliding baffle 21 makes the replacement of the activated carbon filter plate 22 simple and quick.

[0030] A power supply interface 13 is provided at the lower side of the dust collecting box 1, and the power supply interface 13 provides necessary power support for the dust collecting and purifying device.

[0031] As an embodiment of the utility model: when using the dust collection and purification device of the thermal spraying equipment, firstly, the power supply interface 13 is connected to the external power supply, the activated carbon filter plate 22 is placed, the sliding baffle 21 is closed, and the dust collection and purification device is started;

[0032] As the thermal spraying equipment is running, the smoke and waste generated are firstly intercepted by the dust collecting component 2, and the larger particles are collected in the dust collecting component 2. The suction fan 31 starts to work, generating a strong suction force, and the remaining dust-containing gas is sucked into the dust collecting box 1 through the bar hole group 211. In this process, the design of the bar hole group 211 ensures that the gas can enter smoothly. The dust-containing gas entering the dust collecting box 1 is then deeply purified by the activated carbon filter plate 22. The activated carbon filter plate 22 uses its strong adsorption to effectively remove tiny particles, harmful gases and odors in the gas. The support frame 23 firmly supports the activated carbon filter plate 22 to prevent it from being deformed or damaged during operation.

[0033] After double filtration by the filter element 32 and the activated carbon filter plate 22, the clean gas is discharged from the dust collecting box 1 through the exhaust pipe 4, thereby completing the effective treatment of the smoke and waste generated during the thermal spraying process.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
