Description

Technical Field

[0001] This utility model relates to the field of industrial flue gas dust removal technology, and more specifically to a dual-cyclone flue gas collection device. Background Technology

[0002] In industrial production, smoke and dust often occur in the workplace, which not only causes significant smoke pollution to the working environment, but also greatly affects the physical and mental health of workers; therefore, it is essential to install smoke capture facilities.

[0003] In work areas with limited space, overhead cranes or single-beam cranes are often used to assist in the operation of flue gas collection equipment. In order to avoid the dust removal equipment of overhead cranes or single-beam cranes, it is often set as a mobile hood type, and in order to cover the work surface, the hood is set to be particularly large, which leads to a high demand for collection air volume, but the overall collection effect is generally average. In actual work, the workers are still surrounded by smoke and dust, and the working environment cannot be improved.

[0004] Therefore, there is an urgent need for a dual-swirl flue gas capture device. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a dual-swirl flue gas capture device to solve the problems in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0007] A dual-vortex flue gas capture device is connected to a smoke removal duct network with a suction mechanism, including a hollow ventilation riser connected to the smoke removal duct network; a first rotating mechanism for driving the upper part of the hollow ventilation riser to rotate is provided in the middle of the hollow ventilation riser, and the controlled end of the first rotating mechanism is connected to a PLC controller; a hollow ventilation horizontal pipe is vertically connected to the top of the hollow ventilation riser, and the other end of the hollow ventilation horizontal pipe is connected to a connecting pipe arranged parallel to the hollow ventilation riser; the other end of the connecting pipe is connected to a bend with two bends, and a second rotating mechanism is provided at the connection between the bend and the connecting pipe; the other end of the bend is connected to a lifting hose, and the lifting hose is connected to a capture hood.

[0008] The technical solution has been further optimized, with the hollow ventilation riser set vertically.

[0009] To further optimize the technical solution, the first rotating mechanism includes a main geared motor installed on the top side wall of the lower part of the hollow ventilation riser, and the controlled end of the main geared motor is connected to a PLC controller; the rotating shaft of the main geared motor is connected to a gear, and the gear meshes with a main turntable bearing connected between the top port of the lower part of the hollow ventilation riser and the bottom port of the upper part of the hollow ventilation riser.

[0010] To further optimize the technical solution, the second rotating mechanism includes an auxiliary reduction motor mounted on the side wall at the bottom of the connecting pipe, with the controlled end of the auxiliary reduction motor connected to a PLC controller; the shaft of the auxiliary reduction motor is connected to a gear, and the gear meshes with an auxiliary turntable bearing connected between the bottom port of the connecting pipe and the top port of the bend.

[0011] To further optimize the technical solution, the two openings of the bend are oriented in opposite directions, and the length of the bend's top projection is twice the diameter of the trapping hood.

[0012] To further optimize the technical solution, the lifting hose is connected to a lifting motor installed on the bend, which is used to drive the lifting hose to perform lifting and lowering actions.

[0013] Due to the adoption of the above technical solutions, the technical progress achieved by this utility model is as follows.

[0014] This invention provides a dual-vortex flue gas capture device. The longitudinal capture range of the capture hood can be adjusted by setting a suction inlet lifting hose; a first rotating mechanism allows for a large-scale horizontal adjustment of the capture range; and a second rotating mechanism allows for a smaller-scale horizontal adjustment. This allows for more precise movement of the capture hood based on the location of the flue gas, replacing existing large-area capture hoods, reducing the footprint, lightening the equipment structure, and effectively capturing flue gas. This invention has the advantages of flexible hood position adjustment, small footprint, high flexibility, good capture effect, and ease of use. Attached Figure Description

[0016] The components include: 1. Hollow ventilation riser, 2. Main turntable bearing, 3. Main geared motor, 4. Hollow ventilation horizontal pipe, 6. Auxiliary turntable bearing, 7. Auxiliary geared motor, 8. Bend, 9. Lifting hose, 10. Collection hood, and 11. Connecting pipe. Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] A dual-cyclone flue gas capture device is connected to a smoke removal duct network with a suction mechanism, combined with... Figures 1 to 3As shown, it includes a hollow ventilation riser 1, a first rotating mechanism, a hollow ventilation horizontal duct 4, a second rotating mechanism, a bend 8, a lifting hose 9, a collection hood 10, and a connecting pipe 11. The first rotating mechanism includes a main turntable bearing 2 and a main geared motor 3; the second rotating mechanism includes an auxiliary turntable bearing 6 and an auxiliary geared motor 7.

[0019] The hollow ventilation riser 1 is installed vertically, and its bottom end is connected to the smoke removal pipe network.

[0020] A first rotating mechanism is provided in the middle of the hollow ventilation riser 1 to drive the upper part of the hollow ventilation riser 1 to rotate. The first rotating mechanism includes a main geared motor 3 installed on the top side wall of the lower part of the hollow ventilation riser 1. The controlled end of the main geared motor 3 is connected to a PLC controller, which is installed in the electrical control cabinet. The shaft of the main geared motor 3 is connected to a gear, and the gear meshes with a main turntable bearing 2. The main turntable bearing 2 is connected between the top port of the lower part of the hollow ventilation riser 1 and the bottom port of the upper part of the hollow ventilation riser 1 to realize the relative rotation of the upper and lower parts of the hollow ventilation riser 1.

[0021] The first rotating mechanism can drive the upper part of the hollow ventilation riser 1, the hollow ventilation horizontal pipe 4, the connecting pipe 11, the bend 8, the lifting hose 9, and the collection hood to rotate 360° around the axis of the hollow ventilation riser. During the rotation, the smoke near the area swept by the collection hood can be collected. The projection of the area swept during the rotation is a circle, the center of which is the center of the cross-section of the hollow ventilation riser 1, and the radius is the line segment connecting the center of the circle to the farthest end of the collection hood.

[0022] The top of the hollow ventilation riser 1 is connected to a hollow ventilation horizontal pipe 4 that is perpendicular to the hollow ventilation riser 1. The other end of the hollow ventilation horizontal pipe 4 is connected to a connecting pipe 11, which is parallel to the hollow ventilation riser 1.

[0023] The other end of the connecting pipe 11 is connected to a bend 8 with two bends, which is arranged longitudinally. The two openings of the bend 8 face opposite directions and are both located on a straight line parallel to the connecting pipe 11, and the length of the top projection of the bend 8 is twice the diameter of the trap hood 10.

[0024] A second rotating mechanism is provided at the connection between the bend 8 and the connecting pipe 11. The second rotating mechanism includes an auxiliary geared motor 7 mounted on the bottom side wall of the connecting pipe 11, with the controlled end of the auxiliary geared motor 7 connected to a PLC controller. The shaft of the auxiliary geared motor 7 is connected to a gear, which meshes with an auxiliary turntable bearing 6. The auxiliary turntable bearing 6 is connected between the bottom port of the connecting pipe 11 and the top port of the bend 8 to enable rotation of the bend 8 and its lower portion relative to the connecting pipe 11.

[0025] Both the main slewing bearing 2 and the auxiliary slewing bearing 6 are sealed bearings, which prevent smoke and dust from escaping and prevent bearing grease from being sucked into the pipes.

[0026] The bend 8, the lifting hose 9, and the collection hood 10 form a whole that rotates 360° around the axis of the connecting pipe 11. During the rotation, the flue gas near the area swept by the collection hood can be collected. The projection of the area swept during the rotation is a circle, the center of which is the center of the cross-section of the connecting pipe 11, and the radius is the line segment connecting the center of the circle to the farthest end of the collection hood.

[0027] The other end of the bend 8 is connected to a lifting hose 9, which is connected to a collection hood 10. The lifting hose 9 can be connected to a lifting motor installed on the bend 8. When it is inconvenient to manually move the collection hood 10, the lifting hose 9 is used to drive the lifting hose 9 to perform lifting and lowering actions. The controlled end of the lifting motor is connected to a PLC controller.

[0028] In actual use, after the suction mechanism of the smoke removal pipe network is turned on, if the smoke and dust generation point is near the current position of the collection hood, the staff can adjust the lifting hose to align the collection hood with the smoke and dust generation point. The smoke enters from the collection hood with the airflow, and then passes through the lifting hose 9, the bend, the connecting pipe, the hollow ventilation horizontal pipe 4, and the hollow ventilation vertical pipe 1 in sequence before reaching the smoke removal pipe network for processing.

[0029] If there is a distance between the collection hood and the smoke and dust generation point, the auxiliary geared motor is controlled by the PLC controller to drive the bend 8 and its lower part to rotate to the vicinity of the smoke and dust generation point, and the length of the lifting hose is adjusted to make the collection hood aligned with the smoke and dust generation point to effectively collect the smoke and dust.

[0030] If the distance between the collection hood and the smoke / dust generation point is relatively far, the PLC controller controls the main geared motor to drive the upper part of the hollow ventilation riser 1 to rotate the collection hood. After rotating to the vicinity of the smoke / dust generation point, the length of the lifting hose is adjusted to align the collection hood with the smoke / dust generation location for effective collection of the smoke / dust. Alternatively, during operation, the main geared motor and auxiliary geared motor can be simultaneously activated and the lifting hose adjusted to achieve rapid collection of smoke / dust over a large area.
