[0002] In the metallurgical industry, when removing dust from gas sources, in order to achieve better collection effect and better coverage, most of them need to use dust hoods of corresponding size to collect polluted gases such as smoke and steam. In actual work, the dust hood needs to collect the collected gas into the pipeline, and the size of the pipeline is relatively small compared to the area of ​​the dust hood, resulting in uneven gas flow rate when the gas flows into the working surface of the dust hood during dust collection, which in turn causes problems such as surrounding gas escape and energy waste.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The present invention discloses a dust collection hood, please refer to Figures 1 to 3The dust hood includes a dust hood body 1, a plurality of wind equalizing components 2 and a plurality of driving components 3, wherein the dust hood body 1 includes a dust suction inlet 11 and a dust suction outlet 12. The plurality of wind equalizing components 2 are arranged at the dust suction inlet 11, including a mounting frame 21 and a plurality of baffles 22, and the plurality of baffles 22 are detachably and rotatably connected to the mounting frame 21. The rotation angle of the baffles 22 in the wind equalizing component 2 can be adjusted according to actual needs to adjust the flow rate of the impure gas entering different areas of the dust hood, so as to avoid the impure gas escaping due to insufficient gas flow rate in the surrounding areas caused by excessive gas flow rate in a single area. The plurality of driving components 3 are installed on the mounting frame 21, including a driving motor 31 and a driving gear 32, and the driving motor 31 is connected to the driving gear 32 to drive the driving gear 32 to rotate. Among them, the spoiler 22 also includes a transmission gear 27, two adjacent transmission gears 27 are meshed with each other, and the driving gear 32 is meshed with the transmission gear 27. When it is implemented in an air equalization component 2, it can be driven by a driving motor 31 to drive multiple spoilers 22 to rotate together, thereby avoiding the problem that when the air intake in a single area is large, the air intake in the surrounding area is small, resulting in the escape of impurities from the periphery of the dust hood, causing waste of resources and other problems.

[0027] In order to ensure the driving effect of the drive motor 31 on the entire air equalizing component 2, in some embodiments, the mounting frame 21 also includes a mounting plate 23, and the drive motor 31 is installed on the mounting plate 23, so that the drive motor 31 and the drive gear 32 can be arranged close to the spoiler 22, ensuring that no other transmission parts are additionally arranged between the drive motor 31 and the drive gear 32 and the transmission gear 27 and the spoiler 22, thereby reducing the loss of driving force during transmission, thereby achieving smoother and faster transmission with lower energy consumption, speeding up the adjustment speed of the air intake corresponding to the position of the air equalizing component 2 in the dust collector hood, and further preventing the air volume from escaping from the surrounding area.

[0028] Furthermore, in order to enable the multiple spoilers 22 arranged in parallel to rotate in sequence and ensure that the rotation angles are consistent when the drive motor 31 drives the multiple spoilers 22, in some embodiments, the drive motor 31 is arranged in the middle of the wind equalizing component 2. On the one hand, it helps to balance the weight distribution of the entire wind equalizing component 2 and improve the stability of the wind equalizing component 2; on the other hand, it can realize the output of the driving force transmitted by the drive motor 31 through the driving gear 32 to both sides respectively, thereby reducing the loss of driving force during transmission and improving the rotation efficiency of the spoiler 22.

[0029] In some embodiments, the dust hood further includes a sensor 4, which is disposed on the mounting frame 21. The sensor 4 may be a flow sensor 4 or a concentration sensor 4, which detects the gas flow through the wind equalizing component 2 or the dust concentration in the entire space, and determines whether the driving component 3 needs to be used to adjust the angle of the baffle 22 according to the value of the sensor 4 to achieve a suitable flow rate.

[0030] It can be understood that in order to enable the sensor 4 to be stably installed in the air equalizing component 2 and sense the gas in the air equalizing component 2, in some embodiments, the mounting frame 21 also includes a support plate 24, and the support plate 24 is installed on the mounting frame 21 and extends into the air equalizing component 2. The sensor 4 is installed on the support plate 24 for measuring the gas after passing through the baffle plate 22 and transmitting the measured data to an external controller (not shown), further ensuring the accuracy of the numerical value within the range measured by the sensor 4, and the baffle plate 22 can be adjusted to a suitable angle according to the numerical value to adjust the gas flow from the dust suction inlet through the air equalizing component 2.

[0031] In order to ensure that the spoiler 22 can rotate along a certain rotation center under the action of the driving gear 32 and the transmission gear 27, in some embodiments, the spoiler 22 further includes a rotating shaft 25, one end of which is connected to the transmission gear 27, and the other end is rotatably connected to the mounting frame 21. The rotating shaft 25 rotates together with the transmission gear 27, and generates relative rotation with the mounting frame 21, so as to drive the entire spoiler 22 to rotate more smoothly and adjust the gas flow in the air equalization component 2, so as to avoid excessive gas flow in a single area in the dust hood, resulting in insufficient gas flow in the surrounding area, causing the escape of impurity gas.

[0032] In order to ensure that the rotating shaft 25 and the transmission gear 27 can be stably fixed on the mounting frame 21, in some embodiments, the mounting frame 21 also includes a rotating seat 26, which is rotatably connected to the rotating shaft 25. The setting of the rotating seat 26 not only realizes the axial fixation of the rotating shaft 25, but also plays a certain supporting and positioning role for the rotating shaft 25, thereby avoiding wear of the rotating shaft 25 and the mounting frame 21 when the rotating shaft 25 rotates, thereby providing stability for the entire air equalization assembly 2.

[0033] Furthermore, in order to enable the entire spoiler 22 to adjust the air inlet areas on both sides at the same time when rotating, and to achieve the adjustment of the air volume with fewer spoilers 22 in the air equalizing assembly 2, in some embodiments, the rotating shaft 25 is penetrated on the spoiler 22 along the length direction of the spoiler 22, and the rotating shaft 25 coincides with the axis of the spoiler 22. At this time, the rotating shaft 25 is set in the middle of the spoiler 22. One spoiler 22 can adjust the air inlet space on both sides at the same time. The air inlet space in an air equalizing assembly 2 can be adjusted by using fewer spoilers 22. Similarly, the setting of the transmission gear 27 can be reduced, thereby reducing the weight of the entire air equalizing assembly 2, making the overall weight of the dust hood smaller and easier for the operator to operate.

[0034] It can be understood that in order to ensure the transmission efficiency between the driving gear 32 and the transmission gear 27, and to ensure the force balance between the dust hood body 1 and the wind equalizing component 2, in some embodiments, the axes of any two adjacent driving motors 31 are arranged vertically or parallel. On the one hand, the meshing between the driving gear 32 and the transmission gear 27 can be always guaranteed, so as to ensure that the driving force of the driving motor 31 can be transmitted to the spoiler 22 with higher efficiency during rotation, thereby reducing the loss of electricity; on the other hand, by arranging the driving motor 31 on different side walls of the mounting frame 21, it is avoided that when multiple wind equalizing components 2 are spliced ​​together and installed on the dust hood body 1, the center of gravity of the dust hood is unstable due to the excessive weight on one side, thereby affecting the operator's handling effect of using the dust hood to handle dust and debris, thereby limiting the escape of dust and debris within the range of the dust hood to a minimum range.

[0035] In order to ensure that the airflow entering the dust hood body 1 from the dust inlet 11 and then sent to the dust outlet 12 is relatively pure, and to control the sucked dust and debris inside the dust hood to prevent them from migrating to the outside through the dust outlet 12, in some embodiments, the dust hood also includes a filter element (not shown), which is arranged between the air distribution component 2 and the dust outlet 12, and is used to filter the air passing through the dust inlet 11 and the air distribution component 2, and collect the filtered dust into the filter element to prevent the dust from spreading from the dust outlet 12.

[0036] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
