Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and more specifically, to an energy-saving and environmentally friendly spraying equipment. Background Technology

[0002] Energy-saving and environmentally friendly spraying equipment is a new type of coating equipment designed to reduce energy consumption and environmental pollution. Compared with traditional spraying equipment, it has significant advantages such as high efficiency and energy saving, reduced pollution emissions, and improved material utilization.

[0003] When spraying products, the spraying equipment generates a large amount of waste gas. In order to improve environmental protection capabilities, these waste gases are usually treated by RTO combustion. RTO is a regenerative thermal oxidizer that can effectively treat the waste gas generated by spraying. However, after the regenerative thermal oxidizer finishes treating the waste gas, there will be a lot of residual heat in the exhaust gas. If the residual heat is not effectively utilized, it will affect the energy consumption of the device. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0027] Please see Figures 1-5 This utility model discloses an energy-saving and environmentally friendly spraying equipment, including a workbench 1. A conveyor belt 2 is installed on the inner side of the workbench 1. Two mounting frames 3 are fixedly connected to the top of the workbench 1. A spraying mechanism 4 is installed on the left mounting frame 3. Square boxes 5 are fixedly connected to both sides of the left mounting frame 3. Suction grooves 6 are opened at the bottom of the two square boxes 5. A regenerative thermal oxidizer 7 is installed on the back of the workbench 1. The air inlet of the regenerative thermal oxidizer 7 is connected to a three-way pipe 8. The two ends of the front of the three-way pipe 8 are respectively connected to the two square boxes 5. An air pump 9 is installed at one end of the back of the three-way pipe 8. The exhaust pipe of the regenerative thermal oxidizer 7 is connected to a heat exchange pipe 10. The heat exchange pipe 10 has an internal opening. The system includes a cavity 11, the inner wall of which is connected to an air intake pipe 12 and an air outlet pipe 13. An air inlet chamber 14 is provided inside the right mounting frame 3. The inner wall of the air inlet chamber 14 is connected to the air outlet pipe 13. An air outlet groove 15 is provided inside the inner wall of the air inlet chamber 14. An air pump 24 is installed on the air outlet pipe 13. The spraying mechanism 4 includes a material box 401. The bottom of the material box 401 is fixedly connected to the left mounting frame 3. A material cavity 402 is provided inside the left mounting frame 3. An inlet pipe 403 is connected between the inner wall of the material cavity 402 and the material box 401. A water pump 404 is installed on the inlet pipe 403. A uniformly distributed conduit is connected to the bottom of the material cavity 402. A spray nozzle 405 is installed at the bottom end of the conduit.

[0028] In this invention, during use, the conveyor belt 2 is used to transport the product to the area below the nozzle 405. After the product is located below the nozzle 405, the water pump 404 is turned on. The water pump 404 will draw the paint in the material box 401 into the material chamber 402 through the feed pipe 403. The paint will then be sprayed from the nozzle 405 onto the surface of the product, thereby achieving the coating of the product surface.

[0029] During the spraying process, air pump 9 is turned on, drawing air from the two square boxes 5 through the three-way pipe 8. The exhaust gas generated during spraying is then drawn into the suction slot 6 on the square box 5, and enters the air inlet of the regenerative thermal oxidizer 7 through the three-way pipe 8. The regenerative thermal oxidizer 7 then combusts the exhaust gas, and the treated exhaust gas is discharged from the exhaust pipe of the regenerative thermal oxidizer 7. The exhaust gas contains a large amount of heat, and after being heated, it enters the heat exchange tube 10, where it further heats the air in the cavity 11. When the air pump 24 is turned on, it draws heated air into the air inlet chamber 14. The hot air is then ejected from the air outlet 15. The conveyor belt 2 moves the coated product below the air outlet 15. At this time, the hot air is ejected, which can achieve the effect of drying the paint on the product surface, thereby treating the waste gas generated by the coating process. The heat in the treated waste gas can be utilized to dry the product, thereby improving the environmental protection capability of the device, reducing the energy consumption of the device, and improving the practicality of the device.

[0030] Please see Figure 2 The back end of the three-way pipe 8 is fitted with a mounting box 16 that is connected to it, and a filter plate 17 that is slidably connected to the back of the mounting box 16 is inserted therethrough.

[0031] In this invention, after the exhaust gas enters the three-way pipe 8, it will enter the mounting box 16 and pass through the filter plate 17. The particulate matter in the exhaust gas will be filtered, thereby improving the exhaust gas treatment effect of the regenerative thermal oxidizer 7.

[0032] Please see Figure 4 The workbench 1 has a through groove 18 at its bottom, and a scraper 19 is fixedly connected to the inner wall of the through groove 18. The top of the scraper 19 is in contact with the conveyor belt 2.

[0033] In this invention, during the spraying process, paint will adhere to the surface of the conveyor belt 2. During the conveying process, the conveyor belt 2 will slide along the top of the scraper 19, and the scraper 19 will scrape off the adhered paint, thereby achieving the effect of automatic cleaning of the conveyor belt 2.

[0034] Please see Figures 1-4 The bottom of the workbench 1 is fixedly connected to a box 20, and a collection box 21 is slidably connected to the front of the box 20.

[0035] In this invention, the collection box 21 can collect the scraped paint, making it easier for users to clean up the waste and preventing the waste from polluting the work area environment, thereby improving the environmental protection capability of the device.

[0036] Please see Figure 5The bottom end of the suction pipe 12 is fitted with a ring 22 that is threadedly connected to it, and a filter screen 23 is fixedly connected to the inner wall of the ring 22.

[0037] In this invention, when drying the product, outside air enters the cavity 11 through the suction pipe 12 for replenishment. The filter screen 23 can filter the air entering the cavity 11, preventing dusty air from entering the cavity 11. This can prevent hot air from contaminating the product during the drying process and improve the practicality of the device.

[0038] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
