Technical Field

[0001] This utility model relates to the field of metal casting technology, specifically to a dust collection device for casting workshops. Background Technology

[0002] Metal casting is a process in which molten metal is poured into a mold cavity and cooled to obtain a casting. It includes sand casting, die casting, precision casting, etc. During the process, pollutants such as metal dust, molding sand particles, and oil fumes are generated, which harm the environment and health.

[0003] A search revealed Chinese patent CN221085061U, which discloses an air purification device for a foundry workshop. The device includes: a settling tank, casters, a first support rod, a dust collection box, a second support rod, a positioning seat, an induced draft fan, a connecting rod, a collector seat, a nozzle body, a water pump, a water supply pipe, and a filter cartridge. The casters are installed at the bottom of the settling tank and are bolted to it. The first support rod is installed on the inner wall of the bottom of the settling tank and welded to it. The dust collection box is installed at the top of the support rod and welded to it. The positioning seat is welded to the top of the second support rod. This invention improves upon existing air purification equipment for foundry workshops, offering advantages such as a reasonable structural design, good air purification effect, resistance to clogging, and ease of movement. This effectively solves the problems and shortcomings of existing technologies and equipment.

[0004] The aforementioned device uses a movable vacuum box to purify air from multiple directions, which has the advantages of being easy to move and not easily clogged. However, the device can only suck up air at specific locations during use, which can easily lead to better purification effects near the vacuum box and poorer purification effects far from the vacuum box. It cannot achieve multi-point purification through diffusion, thus reducing the purification effect.

[0005] Therefore, there is an urgent need for a dust collection device for foundry workshops to solve the above problems. Utility Model Content

[0021] A connecting plate 11 is fixedly installed on the outside of the sealing shell 2. A connecting plate 12 is rotatably connected to the outer surface of the connecting plate 11. An installation box 13 is fixedly installed on the outer surface of the connecting plate 12. The inside of the installation box 13 is connected to a pipe 14 and a conical hopper 15. The pipe 14 is connected to the bottom of the sealing shell 2.

The inside of the installation box 13 is connected to the inside of the sealing shell 2 through the pipe 14. When vacuuming, outside air can enter the inside of the installation box 13 through the conical hopper 15, and then enter the bottom of the sealing shell 2 through the pipe 14. At this time, the nozzle assembly 3 can process the air entering the sealing shell 2. The purified impurities will fall into the base 1 that runs through the bottom of the sealing shell 2.

[0022] A fixing rope 9 is fixedly installed on the outer surface of the movable frame 8, and a guide plate 22 is fixedly installed on the outer surface of the sealed shell 2. The outer surface of the fixing rope 9 is slidably connected to the inside of the guide plate 22. The fixing rope 9 is a steel wire rope. The guide plate 22 can guide the movement direction of one end of the fixing rope 9. The movement of one end of the fixing rope 9 can be controlled by the up and down movement of the movable frame 8.

Then, the mounting box 13 can be pulled to rotate by moving one end of the fixing rope 9. Conversely, when the ball stop 10 does not enter the inside of the fixing frame 16, the mounting box 13 cannot rotate. When in use, the mounting box 13 that has been rotated to a horizontal state can be moved to a position close to the work station. The unused mounting box 13 can be placed vertically.

[0024] Working principle: When in use, connect the mounting box 13 to be rotated with the baffle ball 10. At this time, control the moving frame 8 to move down. The moving frame 8 can drive one end of the fixed rope 9 to move. At this time, the fixed rope 9 can pull the mounting box 13 to rotate and open, which can move the purification point to the top of the work station. At this time, the induced draft fan 5 draws the outside air into the mounting box 13 and the sealing shell 2 through the conical bucket 15. Then the nozzle assembly 3 can process the impurities in the air and filter them through the filter cartridge 17. When the baffle ball 10 is not connected to the fixed frame 16, this set of mounting boxes 13 will not rotate, and the mounting box 13 can be stored outside the sealing shell 2.
