Description

Technical Field

[0001] This utility model relates to the technical field of ventilation devices for safe production, specifically an explosion-proof ventilation device for dusty environments used in safe production. Background Technology

[0002] In modern industrial production, many sectors such as mining, food processing, and building materials manufacturing are prone to generating high concentrations of dust due to the characteristics of their production processes. When this dust accumulates continuously in confined spaces and reaches its explosive limit, it can easily trigger an explosion, posing a serious threat to personnel safety and production facilities. To control such risks, explosion-proof ventilation devices for dusty environments have become key equipment for safe production. By continuously exhausting dust-laden air and effectively reducing dust concentration, they significantly improve the safety of the working environment.

[0003] Currently, most dust-generating ventilation devices on the market rely on fixed dust hoods. These devices have significant limitations: the suction angle of the hood is not adjustable, meaning it can only cover a predetermined, fixed area. In actual operation, the dust dispersion trajectory is dynamically changing due to factors such as airflow and equipment vibration, and the fixed suction angle cannot adapt to the real-time changes in the dust escape path. Therefore, in the connecting areas between dust hoods or in misaligned areas, dust can easily escape the suction range, forming localized accumulations and continuously creating safety hazards.

[0007] As a preferred option, the diversion mechanism also includes a second fixed plate. Four brackets are fixed to the side wall of the second fixed plate. One side of each bracket is fixed to the side wall of the first fixed plate. A motor is provided on one side of the second fixed plate. The rotating end of the motor is connected to a second gear. The second gear is engaged with four sets of dust suction extension components. The dust suction extension components are rotatably connected to the inside of the first fixed plate. The end of the dust suction extension component away from the tube body has a bent structure.

[0008] As a preferred embodiment, the dust extraction extension assembly includes a rotatably connected conduit inside the first fixed plate, a first gear sleeved on the outer wall of the conduit, one side of the first gear meshing with one side of the second gear, a curved pipe connected through the end of the conduit away from the pipe body, a first air inlet hopper connected to the end of the curved pipe away from the conduit, and a second filter plate fixed to the opening at the end of the first air inlet hopper.

[0009] As a preferred option, the vacuuming extension assembly also includes an end cap inserted into one end of the conduit. The end cap has a hollow internal structure, and an inner core tube is connected through one side of the end cap.

[0010] As a preferred feature, an air distribution block is fixed at the end of the inner core tube away from the end cap, and the air distribution block has a frustum-shaped structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The dust extraction extension components are arranged in a cross shape with four sets connected inside the first fixed plate, forming a multi-channel structure that filters the incoming air from multiple directions, increasing the filtration area, improving filtration efficiency, and further enhancing ventilation safety.

[0013] By installing a third filter plate on the pipe body to initially filter the dust-containing air, the multi-channel structure of the diversion mechanism disperses the dust-containing air and then disperses it into the pipe body. The first filter plate then further filters the air, achieving multi-stage filtration and dispersion treatment.

[0021] 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.

[0022] Example: This utility model provides a technical solution for an explosion-proof ventilation device for dusty environments used in safe production, such as... Figures 1-5 As shown, the device includes a mounting plate 100, on the bottom surface of which two fixing brackets 200 are fixed. A tube body 300 is fixed across the bottom surface of the two fixing brackets 200. A branching mechanism 600 is sleeved on one end of the tube body 300. The branching mechanism 600 has a multi-channel filtration structure inside. One side of the multi-channel filtration structure of the branching mechanism 600 is inserted into the tube body 300. A first fixing cylinder 400 is sleeved on the outer wall of the other end of the tube body 300. A first filter plate 310 is provided on the inner wall of the tube body 300. A reinforcing rib 500 is provided on the outer wall of the tube body 300. Multiple reinforcing ribs 500 are provided along the circumference of the tube body 300. One end of the reinforcing rib 500 is inserted into the first fixing cylinder 400, and the other end of the reinforcing rib 500 is inserted into the second fixing cylinder 610.

[0023] After the air containing dust is initially filtered by the third filter plate 700 on the pipe body 300, the dust-containing air is dispersed by the multi-channel diversion mechanism 600 and then dispersed into the pipe body 300. The first filter plate 310 is then used for further filtration, which realizes multi-stage filtration and dispersion treatment, improves the ventilation efficiency and effect in dusty environments, and ensures the safety of explosion-proof ventilation.

[0024] Multiple reinforcing ribs 500 are provided on the outer wall of the pipe body 300. One end is inserted into the first fixed cylinder 400 and the other end is inserted into the second fixed cylinder 610, which enhances the structural strength of the pipe body 300 and ensures the stability of the ventilation device during long-term use.

[0025] Furthermore, the diversion mechanism 600 includes a second fixed cylinder 610 sleeved on the outer wall of the tube body 300, a first fixed plate 620 fixed inside the second fixed cylinder 610, one end of the tube body 300 attached to the side wall of the first fixed plate 620, and a dust suction expansion component 630 throughly connected inside the first fixed plate 620, with four sets of dust suction expansion components 630 arranged in a cross shape.

[0026] The second fixed cylinder 610 is sleeved on the outer wall of the pipe body 300, realizing the connection between the branching mechanism 600 and the pipe body 300; the first fixed plate 620 is fixed inside the second fixed cylinder 610, and one end of the pipe body 300 is attached to its side wall, ensuring the stability of the connection; the dust collection expansion component 630 is arranged in a cross shape with four sets and is connected through the inside of the first fixed plate 620 to form a multi-channel structure, which filters the incoming air from multiple directions, increases the filtration area, improves the filtration efficiency, and further enhances ventilation safety.

[0027] Furthermore, the diversion mechanism 600 also includes a second fixed plate 650, four brackets 660 are fixed to the side wall of the second fixed plate 650, one side of the brackets 660 is fixed to the side wall of the first fixed plate 620, a motor 640 is provided on one side of the second fixed plate 650, a second gear 670 is connected to the rotating end of the motor 640, the second gear 670 is respectively meshed with four sets of dust suction expansion components 630, the dust suction expansion components 630 are rotatably connected to the inside of the first fixed plate 620, and the end of the dust suction expansion component 630 away from the tube body 300 is a bent structure;

[0028] The rotating end of the motor 640 is connected to the second gear 670, which meshes with four sets of dust extraction extension components 630. Starting the motor 640 drives the second gear 670 to rotate, thereby synchronously driving the four dust extraction extension components 630 to rotate. The dust extraction extension component 630 is rotatably connected inside the first fixed plate 620, and the end away from the tube 300 has a bent structure. During rotation, it can change the air intake direction and extract the air entering the second fixed cylinder 610 from multiple angles, so that the ventilation device can filter the air in the environment more comprehensively, improving ventilation efficiency and safety.

[0029] Furthermore, the dust extraction extension assembly 630 includes a conduit 631 rotatably connected to the inside of the first fixed plate 620. A first gear 633 is sleeved on the outer wall of the conduit 631. One side of the first gear 633 is meshed with one side of the second gear 670. A bend 634 is connected through the end of the conduit 631 away from the tube body 300. A first air inlet 635 is connected to the end of the bend 634 away from the conduit 631. A second filter plate 636 is fixed at the end opening of the first air inlet 635.

[0030] The duct 631 is rotatably connected inside the first fixed plate 620. The first gear 633 sleeved on the outer wall meshes with the second gear 670 and can rotate under the drive of the second gear 670. The bent pipe 634 is connected through to the end of the duct 631 away from the pipe body 300, driving the first air inlet 635 to rotate and realize multi-angle air intake. The second filter plate 636 is fixed at the end opening of the first air inlet 635 to filter the incoming air. The duct 631 introduces the pre-filtered air into the subsequent structure, realizing the complete function from air intake to pre-filtration to transmission, ensuring the effective treatment of air by the ventilation device.

[0031] Furthermore, the vacuuming extension component 630 also includes an end cap 632 inserted into one end of the conduit 631. The end cap 632 has a hollow structure inside, and an inner core tube 637 is connected through one side of the end cap 632. The inner core tube 637 is inserted into the conduit 631, and a gap is provided between the inner core tube 637 and the inner wall of the conduit 631.

[0032] End cap 632 is inserted into one end of duct 631, and its hollow internal structure can temporarily store air. Inner core tube 637 is connected to one side of end cap 632 and inserted into the inside of duct 631. It is spaced apart from the inner wall of duct 631 and can perform secondary filtration on the air entering from duct 631. The setting of inner core tube 637 optimizes the air flow path inside the dust collection extension component 630, so that the air is initially filtered by the second filter plate 636 and then further filtered by the inner core tube 637, which improves the filtration accuracy of the ventilation device and enhances ventilation safety.

[0033] Furthermore, an air distribution block 6371 is fixed to the end of the inner core tube 637 away from the end cap 632. The air distribution block 6371 has a frustum-shaped structure. With the frustum-shaped air distribution block 6371 fixed to the end of the inner core tube 637 away from the end cap 632, when air passes through the inner core tube 637, the air distribution block 6371 can evenly distribute the air, preventing the air from concentrating and being discharged from one place. This allows the air filtered by the inner core tube 637 to be discharged more evenly, improving the air treatment effect of the ventilation device and further ensuring ventilation safety.

[0034] Specifically, the external ventilation system is connected to the duct body 300. Air from the dusty environment enters the second fixed cylinder 610. The starting motor 640 drives the second gear 670 to rotate. The second gear 670 synchronously drives the four first gears 633 to rotate. The first gears 633 drive the duct 631 to rotate. The duct 631 drives the bend 634 to rotate. The rotation of the bend 634 causes the first air inlet hopper 635 to rotate, changing its orientation. This allows for multi-angle extraction of air entering the second fixed cylinder 610. The air is then filtered through the second filter plate 636 and enters the bend 634. The air is then guided into the duct 631, filtered through the inner core tube 637 within the four ducts 631, and discharged from the end cover 632. Finally, the air is filtered again by the first filter plate 310, thus achieving multi-stage and multi-channel filtration ventilation and improving ventilation safety.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
