[0001] The utility model belongs to the technical field of machining, and in particular relates to a dust removal device for machine tools. Background Art

[0002] Machining is the abbreviation of mechanical processing, which refers to the processing technology of removing materials through precise mechanical processing. However, a large amount of dust will be generated during the processing. This dust will not only penetrate into the interior of the machine, causing damage to equipment and components and affecting the life of the machine, but also enter the air and float in the air, making the working environment harsh. Working in this environment for a long time will seriously threaten the respiratory health of the staff.

[0003] At present, in order to improve the air quality of the processing environment, a common method is to add an exhaust system in the processing workshop to achieve indoor and outdoor air circulation, so as to discharge the dust floating in the air, reduce the accumulation of dust, improve the indoor air quality, and reduce the harm to the workers; although this dust removal method improves the air quality of the workshop, dust will still remain in the air and cannot be completely eliminated; secondly, in the process of indoor and outdoor air circulation, indoor dust will be discharged into the outdoor air, causing pollution to the outdoor air.

At this time, a row of the air nozzles 504 are facing the filter element 3. During operation, the connecting plate 503 is driven by the screw slide 501 to move above the filter element 3, so that the air nozzle 504 removes dust from the filter element 3; wherein, in order to prevent the air pipe connected to the connecting hole 5032 from being entangled or damaged when the connecting plate 503 is displaced during the dust removal process of the filter element 3, the wind blowing mechanism 5 also includes a tank chain 505 for installing the air pipe; in addition, in order to prevent air leakage at the orifice of the air hole 5031, a screw plug 9 is installed at the orifice of the air hole 5031.

[0033] For further information, see Figure 2 As shown, two groups of water spray mist mechanisms 6 are provided, and the two groups of water spray mist mechanisms 6 are symmetrically arranged; see Figure 6-9 As shown, in this embodiment, each group of the water spray mechanism 6 includes a first connecting rod 601, and a second connecting rod 602 is respectively provided at both ends of the first connecting rod 601 to form an I-shaped structure; wherein, a first water hole 6011 is opened in the first connecting rod 601, and a second water hole 6021 is respectively opened in the second connecting rod 602, and the first water hole 6011 and the second water hole 6021 are connected; a pipe 603 connected to the first water hole 6011 is provided in the middle of the first connecting rod 601, and a row of water nozzles 604 connected to the second water hole 6021 are respectively provided on the second connecting rod 602; during installation, refer to Figure 2 As shown, the second connecting rod 602 is fixed to the box body 1 through a corresponding supporting seat.

At this time, the motor 201 drives the exhaust fan 202 to rotate, driving the air into the suction duct assembly 7, and then entering the box body 1 through the suction port. After the dust in the air is filtered by the filter element 3, the air is discharged through the outlet to achieve air filtering.

[0039] After a period of filtering operation, as the dust intercepted on the filter element 3 accumulates, the pores on the filter element 3 will be blocked, resulting in a decrease in the air volume passing through the filter element 3; at this time, the air supply mechanism starts to supply air to the wind blowing mechanism 5, while the screw slide 501 drives the connecting plate 503 to move above the filter element 3, so that the air nozzle 504 blows air to the filter element 3 to remove the dust from the filter element 3; at the same time, the water supply mechanism starts to supply water to the water mist mechanism 6, and the water is sprayed out in the form of mist through the water nozzle 604, which will condense the dust blown off the filter element 3 and floating in the box 1 into small balls, and drop them into the dust collecting box 4.

[0040] When the dust in the dust box 4 is full, the dust box 4 is taken out by pulling and the dust is poured into a designated location.

[0041] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
