Description

Technical Field

[0001] This utility model relates to the field of negative pressure dust collector technology, specifically a high negative pressure dust collector for a bedroom suitable for welding workstations. Background Technology

[0002] With the improvement of industrial automation, robotic welding workstations are increasingly widely used in fields such as machinery manufacturing, automobile manufacturing, and construction machinery. They have become core equipment for improving welding efficiency and ensuring welding quality. During the welding process, a large amount of welding fumes containing metal oxides, harmful gases, and fine dust are generated. These fumes not only pollute the working environment, but also seriously endanger human health if inhaled by operators over a long period of time. At the same time, the fumes adhering to the surface of the equipment will also affect the operating accuracy and service life of the welding workstation. Therefore, the efficient purification of welding fumes has become a key requirement for welding workstation supporting equipment.

[0003] There is a lack of miniaturized and integrated dust removal equipment specifically adapted to welding workstations on the market. Most existing dust removal equipment is a general-purpose large-scale dust removal system, which is relatively large in size and occupies a lot of space when adapted to welding workstations, and has high requirements for installation conditions.

[0004] Therefore, we propose a high negative pressure dust collector for bedrooms suitable for welding workstations to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figure 1-4 As shown in the figure, an embodiment of this utility model proposes a bedroom high negative pressure dust collector suitable for welding workstations, including a dust collection box 1 and a negative pressure suction box 2 fixed to the side of the dust collection box 1. The dust collection box 1 and the negative pressure suction box 2 are connected side by side, and the top of the dust collection box 1 is provided with a rotatable top cover for easy maintenance of the internal structure. The dust collection box 1 and the negative pressure suction box 2 are welded to the welding workstation. At the same time, a large-sized filter screen is provided on the surface of the negative pressure suction box 2 to provide sufficient heat dissipation inside. An airflow corrugated pipe 3 is connected inside the dust collection box 1, and the front end of the airflow corrugated pipe 3 is connected to the dust collection kit of the welding workstation. The dust collection kit is used in conjunction with the welding head of the welding workstation to introduce the gas that needs to be dusted into the dust collection box 1 from the airflow corrugated pipe 3.

[0028] A set of dust collection plates 4 are fixed inside the dust collection box 1, and the dust collection plates 4 have cavities. A filter cartridge body 5 is installed inside the cavity. The filter cartridge body 5 is made of PTFE microporous membrane and polyester fiber. It purifies welding fumes by using the micro-permeable structure formed on the surface of the filter material to block particulate matter in the gas. To facilitate the assembly and disassembly of the filter cartridge body 5, a longitudinal groove is provided inside the dust collection plate 4, and a slider is provided on the outer wall of the filter cartridge body 5 to slide longitudinally with the groove. This allows the filter cartridge body 5 to move longitudinally for assembly and disassembly. The bottom of the dust collection plate 4 is open. The airflow corrugated pipe 3 passes through the dust collection box 1 and enters the cavity of the dust collection box 1. The airflow enters the filter cartridge body 5 through the open window at the bottom of the dust collection plate 4 and is filtered by the filter cartridge body 5. A guide plate 14 with an inclined design is also fixed on the inner wall of the dust collection box 1, below the filter cartridge body 5. Larger dust particles fall naturally under gravity after entering the dust collection box 1 and move along... The inclined guide plate 14 moves downward, and a movable track plate 12 fixed to the inner wall of the dust collector 1 is installed below the guide plate 14, allowing the dust collector 13 to be slidably pulled out from the movable track plate 12. The top of the dust collector 13 is open, allowing larger dust particles to fall from the guide plate 14 into the dust collector 13 for collection. The dust collector 13 can be pulled out for cleaning later. A back-blowing device 6 is also installed on the inner wall of the dust collector 1 via a bracket. One end of the bracket is installed on the side of the fan suction pipe 7, and the back-blowing device... 6. The air tank, solenoid valve, and lotus nozzle are connected to an external compressed air source through an air pipe. The electronic control system issues instructions to remove the dust adhering to the surface of the filter cartridge body 5 by blowing compressed air at specified time intervals. The particulate dust is captured on the outer surface of the filter element of the filter cartridge body 5. When the blocked dust continues to accumulate on the surface of the filter element, the filter cartridge is cleaned by blowing through the solenoid valve of the back-blowing device 6, so that the dust particles deposited on the filter element are detached from the surface of the filter element and fall to the bottom under the action of vibration.

[0029] A fan suction pipe 7 is installed on the inner wall of the dust collection box 1, and one end of the fan suction pipe 7 passes through a connecting pipe 8 that passes through the outer wall between the dust collection box 1 and the negative pressure suction box 2. A high negative pressure fan 9 is installed inside the negative pressure suction box 2, so that the filtered gas enters the high negative pressure fan 9 through the fan suction pipe 7 and the connecting pipe 8. The bottom of the high negative pressure fan 9 is connected to an exhaust pipe 10, and the opening of the exhaust pipe 10 extends out of the bottom of the negative pressure suction box 2, so that the filtered gas can be discharged from the end of the exhaust pipe 10 to the outside of the dust collection box 1. An electrical control box 11 for controlling the equipment is also installed at the front end of the negative pressure suction box 2. The electrical control box 11 contains the electrical control system of the dust collection equipment, and function switches such as equipment start and stop control and linkage control with the robot.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
