Detailed Implementation

[0020] 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.

[0021] Example

[0022] Please see Figures 1 to 5 This embodiment of the present invention provides a technical solution: a safety collection device for explosive metal dust from machining, comprising a collection box 100 and a connecting pipe 200 connected to one side of the collection box 100. The connecting pipe 200 can be externally connected to a blower, which draws the dust into the connecting pipe 200 through suction and finally transports it into the collection box 100. A mesh cover assembly 300 is provided on the collection box 100. The mesh cover assembly 300 includes a filter mesh cover 301, a fixing frame 302, a top groove 303, a top box 304, a fixing handle 305, an air pump 306, and a limiting block 307. The fixing frame 302 is fixed inside the collection box 100, and the filter mesh cover 301 is movably installed inside the collection box 100 and located on one side of the fixing frame 302. The filter mesh cover 301 can intercept and filter the dust. A limiting block 307 with mutual offset and compression is provided between the two sides of the filter screen 301 and the fixed frame 302. The top groove 303 is opened on the top of the collection box 100. The top box 304 is fixed on the outside of the top groove 303. The top of the filter screen 301 extends into the top groove 303 and is fixedly connected to the fixed handle 305. The fixed handle 305 extends out of the top box 304. The air pump 306 is fixed on the top of the collection box 100, and the output shaft is movably connected to the end of the fixed handle 305. By starting the air pump 306, the fixed handle 305 and the filter screen 301 can be driven to move up and down. When the filter screen 301 moves, the limiting block 307 between it and the fixed frame 302 can continuously squeeze and impact, thereby causing the filter screen 301 to vibrate and shake the dust off the surface of the filter screen 301, thus playing the role of dust cleaning.

[0023] In this embodiment, preferably, the mesh cover assembly 300 further includes side strips 308 and side grooves 309. The side strips 308 are symmetrically fixed on both sides of the filter mesh cover 301 and are slidably inserted into the side grooves 309 opened on the inner wall of the collection box 100 to complete the sliding connection between the filter mesh cover 301 and the inner wall of the collection box 100.

[0024] In this embodiment, preferably, the mesh cover assembly 300 further includes rubber pads 3010. The rubber pads 3010 are symmetrically distributed on the inner walls of both sides of the side groove 309 and are in contact with the sides of the side strip 308. The rubber pads 3010 are elastic, so that the filter mesh cover 301 has a space that can vibrate.

[0025] In this embodiment, preferably, the limiting blocks 307 are evenly distributed on both sides of the filter screen 301 and the fixing frame 302. The surface of the limiting blocks 307 is curved to avoid the limiting blocks 307 from being too tightly engaged, which would prevent the filter screen 301 from being able to complete the lifting and lowering movement.

[0026] In this embodiment, preferably, a sliding plate is slidably connected to the bottom surface of the extended end of the fixed handle 305. The sliding plate is fixedly connected to the output shaft of the air pump 306, thus completing the movable connection between the output shaft of the air pump 306 and the fixed handle 305. The purpose of the movable connection is that if the output shaft of the air pump 306 is fixedly connected to the fixed handle 305, it will limit the vibration of the filter screen 301.

[0027] In this embodiment, preferably, the bottom end of the collection box 100 is symmetrically provided with support legs 500, which support the collection box 100 and suspend it in the air, leaving space between the collection box 100 and the ground.

[0028] In this embodiment, preferably, a conductive component 400 is provided inside the collection box 100. The conductive component 400 can transmit the static electricity generated inside the collection box 100 to prevent explosion caused by static electricity. The conductive component 400 includes an aluminum foil layer 401, a bottom groove 402, a copper conductive sheet 403, and a copper contact sheet 404. The aluminum foil layer 401 is attached to the inner wall of the collection box 100 and has conductive properties. The bottom groove 402 is opened at the bottom of the collection box 100. The top of the copper conductive sheet 403 passes through the bottom groove 402 and contacts the aluminum foil layer 401. The bottom of the copper conductive sheet 403 is fixedly connected to the copper contact sheet 404. The copper contact sheet 404 is flush with the bottom of the support leg 500. When the collection box 100 is placed, the copper contact sheet 404 can contact the ground, thereby conducting the static electricity inside the collection box 100 to the ground.

[0029] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
