[0023] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0024] This utility model provides an overall structural schematic diagram of an embodiment of a portable dust collection device for explosion-proof areas, including: Please see Figures 1-7 This utility model provides a technical solution: See also Figure 1 Figure 7 As shown, a movable dust collection device for explosion-proof areas includes a dust collector body 1 and a feed inlet 13 located at the top of the dust collector body 1. A first baffle 233 and a second baffle 263 are slidably connected to the inner wall of the feed inlet 13. An adjustment component 2 is provided on the inner wall of the feed inlet 13, and a cleaning component 3 is provided on one side of the adjustment component 2. The adjustment component 2 is driven by a motor to alternately raise and lower the first baffle 233 and the second baffle 263 inside the feed inlet 13, while cleaning the first baffle 233 and the second baffle 263. This helps to reduce excess deposits on the surface of the first baffle 233 or the second baffle 263, reducing the adsorption pressure of the fan while maintaining the dust collection effect, and thus extending the service life of the device.

[0025] See also Figure 2 Figure 4 As shown, the adjusting assembly 2 includes a fixed base 21, a drive rod 22 is sleeved inside the fixed base 21, a slider 222 is sleeved on the outer circumference of the drive rod 22, a groove 221 is provided on the side wall of the feed inlet 13, the slider 222 is slidably connected to the groove 221, a track 24 is inserted into the top of the outer circumference of the drive rod 22, an auxiliary rod 23 is sleeved on the inner wall of the track 24, a moving block 232 is sleeved on the outer circumference of the auxiliary rod 23, and an auxiliary groove 231 is provided on the side wall of the feed inlet 13. An auxiliary block 232 is slidably provided on the inner wall of 231. The top of the side wall of the movable block 232 is connected to a baffle 233 by bolts. The drive rod 22 is driven by a motor to rotate in coordination with the track 24 and the track 28, so that while the baffle 233 is raised and lowered, the baffle 263 moves in opposite directions. This ensures that there is always a baffle to protect against external particles, reducing the possibility of too many particles entering the device and causing damage, thereby maintaining the service life of the fan inside the device.

[0026] See also Figure 2 Figure 4 As shown, a third track 28 is provided above track 1 24. A vertical rod 25 is sleeved on the inner wall of track 3 28, and a vertical block 252 is sleeved on the outer circumference of the vertical rod 25. A vertical groove 251 is opened on the inner wall of the feed inlet 13, and the vertical groove 251 is slidably connected to the vertical block 252. Track 2 27 is inserted into the top of the outer circumference of the vertical rod 25. A locking rod 26 is sleeved on the inner wall of track 2 27, and a locking block 262 is sleeved on the outer circumference of the locking rod 26. A slot 261 is opened on the inner wall of the feed inlet 13, and the locking block 262 is slidably connected to the slot 261. The top of the side wall of the locking block 262 is connected to a baffle 263 through a bearing. Track 2 27 is rotated by track 3 28, so that the baffle 263 can rise and fall on the inner wall of the vertical groove 251. This facilitates the blocking of particulate dust in the feed inlet 13 in conjunction with the baffle 1 233, thereby reducing the pressure on the internal fan of the device.

[0027] See also Figure 4 Figure 7 As shown, specifically, the cleaning component 3 includes a concave plate 33, and grooves 31 are provided at the bottom of the slide 221 and the vertical groove 251. The side walls of the slider 222 and the vertical block 252 are connected to the concave plate 33 by bolts. The bottom of the concave plate 33 is connected to a cleaning roller 32 by a bearing. A brush 36 is sleeved on the outer circumference of the cleaning roller 32. The cleaning roller 32 can be used to clean the slider 222 and the vertical block 252 during the movement of the slider 222 and the vertical block 252, so that the baffle 1 233 or baffle 263 can be raised and lowered.

[0028] See also Figure 6 Figure 7 As shown, a gear 34 is sleeved on the outer circumference of one end of the cleaning roller 32. The gear 34 is meshed with a rack 35. The sidewalls of the rack 35 are respectively connected to the slide groove 221 and the vertical groove 251 by bolts. The meshing of the gear 34 with the rack 35 facilitates the rotation of the brush 36 during the descent of the cleaning roller 32 in conjunction with the concave plate 33, thereby achieving the purpose of cleaning the first baffle 233 and the second baffle 263.

[0029] See also Figure 3 Figure 5 As shown, specifically, the top of the auxiliary groove 231 is connected to a cover plate 241 via a bearing, and the top of the slot 261 is connected to a cover plate 271 via a bearing. The cover plates cover the top of the slot 261 and the auxiliary groove 231, which helps to reduce the possibility of dust entering from the top gap when the device is in dust collection mode.

[0030] See also Figure 2As shown, the threads on the outer circumference of the auxiliary rod 23 and the outer circumference of the locking rod 26 have the same thread direction, and the threads on the outer circumference of the drive rod 22 and the outer circumference of the vertical rod 25 have the same thread direction. Through the threaded drive rod 22 and locking rod 26, the slider 222 and the locking block 262 can move relative to each other. In conjunction with the vertical block 252 and the auxiliary rod 23, which also move relative to each other, the baffle 1 233 and the baffle 263 can move in opposite directions with the cleaning roller 32.

[0031] See also Figure 6 Figure 7 As shown, the cleaning roller 32 is equipped with a motor core inside, and the inner wall of the groove 31 is connected to the scraper 37 by bolts. Through the rapid rotation or vibration of the motor core, the brush 36 on the surface of the cleaning roller 32 can generate high-frequency vibration, thereby discharging fine dust and performing secondary cleaning through the scraper 37.

[0032] The motor mechanism is existing technology and will not be discussed in detail here.

[0033] See also Figure 1 As shown, the bottom of the dust collector body 1 is provided with a discharge port 14, which facilitates the timely discharge of captured dust.

[0034] See also Figure 1 As shown, the bottom of the dust collector body 1 is connected to multiple casters 11 by bolts, and the top of the dust collector body 1 is connected to an explosion-proof socket 12 by wires. The casters 11 make it easy to move the dust collector body 1 in the required operating environment and to move it away from the site in time after the operation is completed, thereby increasing the dust collection range. The explosion-proof socket 12 facilitates its use in explosion-proof areas.

[0035] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0036] Combination Figures 1-7 The following is a description of a portable dust collection device for use in explosion-proof areas, as described in this embodiment: 1: When using this type of mobile dust collection device for explosion-proof areas, the operator moves the dust collector body 1 to a suitable position using the casters 11, connects the power supply to the dust collector body 1 through the explosion-proof socket 12, collects dust from the surrounding environment through the feed inlet 13, and discharges excess dust through the discharge outlet 14. 2. When the device needs to block larger particles in external dust, the drive motor causes the drive rod 22 to rotate. With the combined action of the first track 24, the second track 27, and the third track 28, the auxiliary rod 23, the vertical rod 25, and the locking rod 26 all rotate simultaneously with the drive rod 22. This facilitates the simultaneous movement of the second track 263 against the first track 233 during its lifting and lowering process. At the same time, the cleaning roller 32 and the brush 36 also move against the first track 233 and the second track 263, respectively. In other words, the slider 222 drives the first track 233... As the inner wall of the chute 221 rises, the moving block 232 drives one of the cleaning rollers 32 and the brush 36 to descend along the inner wall of the auxiliary chute 231. At the same time, the vertical block 252 drives the baffle 263 to descend along the inner wall of the vertical chute 251, and the locking block 262 also drives the other cleaning roller 32 and the brush 36 to rise along the inner wall of the locking groove 261. This ensures that the inner wall of the feed inlet 13 is always blocked by a baffle to prevent particulate dust from entering the fan and interfering with its operation, thus maintaining the overall service life of the device.

[0037] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
