The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The utility model provides a powder coating processing dust reduction device, such as Figure 1-4 As shown, the powder coating processing dust reduction equipment includes: a base 1; a box body 2, wherein the box body 2 is fixedly mounted on the top of the base 1; a high-pressure fan 3, wherein the high-pressure fan 3 is fixedly mounted on the top of the base 1; an air inlet pipe 4, wherein the air inlet pipe 4 is fixedly mounted on the air inlet end of the high-pressure fan 3 and extends into the box body 2; a support ring 5, wherein the support ring 5 is arranged in the box body 2, wherein a filter screen 6 is fixedly mounted in the support ring 5; a connecting pipe 7, wherein the connecting pipe 7 is fixedly mounted on the top of the box body 2, wherein a dust suction pipe 8 is fixedly mounted on the air inlet end of the connecting pipe 7; and a discharge assembly, wherein the discharge assembly is arranged on the box body 2, and wherein the discharge assembly is used for assisting in discharging the coating dust raw materials in the box body 2.

[0021] In this embodiment, the base 1 and the box body 2 constitute the main structure of the equipment, providing an installation foundation for other components. The combination of the high-pressure fan 3 and the air inlet pipe 4 is used to generate airflow, which is introduced into the box body 2 through the air inlet pipe 4 to form a dust collection effect. The setting of the support ring 5 and the filter screen 6 further enhances the dust removal ability of the equipment. The filter screen 6 can block the powder raw material from entering the high-pressure fan 3, preventing the proportioning accuracy of the powder raw material from being affected. The dust suction pipe 8 can suck in the generated dust and then enter the inside of the box body 2 through the connecting pipe 7. After being filtered by the filter screen 6, the clean air can be discharged, while the powder raw material is left in the box body 2. The setting of the discharge component enables the equipment to conveniently discharge the collected paint dust raw materials, which is convenient for subsequent cleaning and processing.

[0022] In a further preferred embodiment of the utility model, the discharge assembly includes a discharge pipe 9, a filter bag 10, a branch pipe 11 and two first solenoid valves 12, the discharge pipe 9 is fixedly mounted on one side of the box body 2, the branch pipe 11 is fixedly mounted on the discharge pipe 9 and connected to the air inlet pipe 4, the filter bag 10 is arranged between the discharge pipe 9 and the branch pipe 11, and the two first solenoid valves 12 are respectively arranged on the air inlet pipe 4 and the branch pipe 11.

[0023] In this embodiment, the discharge pipe 9 is used to discharge the collected paint dust raw materials. The design of the branch pipe 11 enables the discharge pipe 9 to be connected with the air inlet pipe 4, which provides convenience for the subsequent discharge operation. The filter bag 10 plays a key filtering role. During the discharge process, the filter bag 10 can block the paint dust raw materials from entering the air inlet pipe 4, ensuring the normal operation of the high-pressure fan 3, while also preventing the waste of powder raw materials and the reduction of the proportioning accuracy. By controlling the switch of the first solenoid valve 12, the on-off control of the air inlet pipe 4 and the branch pipe 11 can be achieved. When discharge is required, the first solenoid valve 12 connected to the branch pipe 11 can be opened to connect the discharge pipe 9 with the air inlet pipe 4, and the paint dust raw materials enter the discharge pipe 9 under the action of the airflow. When discharge is not required, the first solenoid valve 12 can be closed to block the connection between the discharge pipe 9 and the air inlet pipe 4, thereby preventing dust leakage.

[0024] In a further preferred embodiment of the utility model, an exhaust pipe 13 is fixedly installed at the exhaust end of the high-pressure fan 3, the exhaust pipe 13 is connected to the discharge pipe 9, a fixed pipe 14 is installed on the exhaust pipe 13, and a second solenoid valve 15 is provided on both the exhaust pipe 13 and the fixed pipe 14.

[0025] In this embodiment, the design of the exhaust pipe 13 allows the airflow generated by the high-pressure fan 3 to be discharged more smoothly, and also provides more flexibility for the discharging operation. The setting of the second solenoid valve 15 makes it possible to control the on-off of the exhaust pipe 13 and the fixed pipe 14 according to actual needs. For example, when discharging, the second solenoid valve 15 connected to the discharge pipe 9 can be opened to allow the airflow to smoothly enter the discharge pipe 9 and help discharge the paint dust raw materials. In other cases, the solenoid valve can be closed to prevent unnecessary loss of airflow.

[0026] In a further preferred embodiment of the utility model, two electric telescopic rods 16 are fixedly installed on the top of the box body 2, and a mounting frame 17 is fixed on the output rods of the two electric telescopic rods 16. A baffle 18 is installed on the mounting frame 17, and the baffle 18 can contact the connecting pipe 7. A connecting rod is installed between the mounting frame 17 and the support ring 5.

[0027] In this embodiment, when the electric telescopic rod 16 is extended or retracted, it will drive the mounting frame 17 and the baffle 18 to move together, thereby shielding or exposing the connecting pipe 7. This design can quickly adjust the degree of opening of the connecting pipe 7 when needed, which is convenient for different operations. The function of the connecting rod is to enhance the stability of the mounting frame 17, and at the same time, it can enable the support ring 5 and the baffle 18 to achieve synchronous movement.

[0028] In a further preferred embodiment of the utility model, an isolation plate 20 is fixedly installed on the top of the support ring 5, and a sealing ring 21 is fixedly installed on the side of the isolation plate 20 close to the discharge pipe 9, and the sealing ring 21 is in contact with the inner wall of the box body 2.

[0029] In this embodiment, the setting of the isolation plate 20 plays an isolation role, effectively preventing the high-pressure fan 3 from having difficulty in normal dust collection, and the introduction of the sealing ring 21 enhances the sealing between the isolation plate 20 and the inner wall of the box body 2, further preventing the leakage and diffusion of paint dust raw materials.

[0030] In a further preferred embodiment of the utility model, a ventilation tube is fixedly installed on the box body 2, a valve is provided on the ventilation tube, a battery is provided on the base 1, and the two electric telescopic rods 16 are both covered with rubber protective sleeves 19.

[0031] In this embodiment, the provision of the ventilation tube allows the air inside the box 2 to be exchanged with the outside, which helps to maintain air circulation inside the box 2. The introduction of the battery allows the device to work independently without an external power supply, thereby enhancing the portability and practicality of the device. The rubber protective cover 19 has good elasticity and wear resistance, and can effectively protect the surface of the electric telescopic rod 16 and extend its service life.

[0032] In a further preferred embodiment of the present invention, a plurality of universal wheels 22 are fixedly mounted on the bottom of the base 1 , and a self-locking structure is provided on the plurality of universal wheels 22 , and a plurality of dust suction ports are provided on the dust suction pipe 8 .

[0033] In this embodiment, the universal wheel 22 allows the device to be easily moved and relocated, making it convenient to use in different workplaces. The self-locking structure can fix the position of the device when needed to prevent it from sliding or moving during use, thereby ensuring work stability and safety. The dust suction port can more effectively absorb dust, thereby improving the dust reduction efficiency of the device. At the same time, the provision of multiple dust suction ports also makes the dust suction range wider, which can cover a larger working area, further improving the practicality of the device.

[0034] In summary, compared with the related art, the present device can absorb the dust generated by the mixed powder coating raw materials by setting the box 2, the high-pressure fan 3, the air inlet pipe 4, the connecting pipe 7 and the dust suction pipe 8. The support ring 5 and the filter screen 6 can prevent the powder from directly entering the high-pressure fan 3 and causing damage to it. The discharge pipe 9 can directly discharge the collected dust into the powder coating processing equipment again.
