Description
Technical Field
[0001] This utility model belongs to the field of smoke and dust treatment technology, specifically, it relates to a rotating support device for a smoke and dust collection hood. Background Technology
[0002] In many industrial production sectors today, such as steel smelting, chemical synthesis, building materials manufacturing, and machinery processing, the production process is accompanied by the generation of a large amount of smoke and dust. This smoke and dust not only contains various fine particulate matter, but also often contains toxic and harmful gases. If it is discharged indiscriminately, it will cause serious pollution to the environment, endanger the surrounding ecological balance, and pose a huge threat to the health of on-site workers, causing many health problems such as respiratory diseases and lung damage.
[0003] Currently, most traditional dust collection hoods are fixed in place, and their position and angle are difficult to change after installation. However, in actual production scenarios, the height and direction of dust sources are complex and varied. Taking a steel plant as an example, when steel is tapped from a converter, dust will be ejected upwards in a columnar shape. In subsequent refining and continuous casting processes, dust will escape from equipment gaps or openings at different heights and angles. Therefore, fixed collection hoods can only cover a limited area and cannot effectively capture dust, allowing a large amount of dust to escape from the periphery of the collection hood, thus reducing the dust collection effect. In view of this, this utility model is proposed. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a rotating support device for a dust collection hood that can overcome or at least partially solve the above problems.
[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0006] A rotating support device for a dust collection hood includes a hydraulic telescopic component and a mounting base fixedly connected to the telescopic end of the hydraulic telescopic component; a rotating shaft rotatably connected to the mounting base; a frame fixedly connected to the end of the rotating shaft away from the mounting base; a cylinder fixedly connected to the mounting base via a support rod, wherein the cylinder is rotatably connected to the support rod; and a connecting rod fixedly connected to the rotating shaft, wherein the end of the connecting rod away from the rotating shaft is rotatably connected to the telescopic end of the cylinder.
[0007] Preferably, a limiting groove is provided in the mounting base, a rotating block is rotatably connected in the limiting groove, and one end of the rotating shaft passing through the limiting groove is fixedly connected to the rotating block.
[0008] To improve the stability of the frame when the rotating shaft drives it to adjust the angle, multiple balls are equidistantly arranged on the upper circumference of the mounting base, and a support ring is fixedly connected to the rotating shaft, with the balls in contact with the support ring.
[0009] To drive the frame to rise or fall, preferably, the hydraulic telescopic component includes a cylinder and a piston disc slidably connected to the cylinder. A piston rod is fixedly connected to the piston disc, and one end of the piston rod that passes through the cylinder is fixedly connected to a mounting base. Both the upper and lower side walls of the cylinder are fixedly connected to injection pipes.
[0010] Furthermore, it also includes a base for fixing the cylinder body, the base being fixedly connected to the lower end of the cylinder body, and the base having mounting holes.
[0011] Preferably, the frame has a dust collection chamber, and the side wall of the frame has multiple dust collection ports that are equidistant from each other and communicate with the dust collection chamber. The frame is provided with a dust collection pipe that communicates with the dust collection chamber.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0021] Example 1:
[0022] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A rotating support device for a dust collection hood includes a hydraulic telescopic component and a mounting base 4 fixedly connected to the telescopic end of the hydraulic telescopic component; a rotating shaft 402 rotatably connected to the mounting base 4; a frame 3 fixedly connected to the end of the rotating shaft 402 away from the mounting base 4; a cylinder 405 fixedly connected to the mounting base 4 via a support rod 404, wherein the cylinder 405 is rotatably connected to the support rod 404; and a connecting rod 406 fixedly connected to the rotating shaft 402, wherein the end of the connecting rod 406 away from the rotating shaft 402 is rotatably connected to the telescopic end of the cylinder 405.
[0023] The hydraulic telescopic component includes a cylinder body 2 and a piston disc 201 slidably connected inside the cylinder body 2. A piston rod 202 is fixedly connected to the piston disc 201. One end of the piston rod 202 passes through the cylinder body 2 and is fixedly connected to the mounting base 4. Both the upper and lower side walls of the cylinder body 2 are fixedly connected to injection pipes 203.
[0024] In use, first install the dust collection hood onto the frame 3. Then, based on the height of the dust generation source on site, when it is necessary to raise the dust collection hood installed on the frame 3, high-pressure liquid can be injected into the cylinder 2 from the injection pipe 203 at the lower end of the cylinder 2. The liquid pushes the piston disc 201 upward, and the piston rod 202 extends, causing it to drive the mounting base 4 to rise. At the same time, the mounting base 4 can drive the dust collection hood installed on the frame 3 to rise synchronously through the rotating shaft 402. Conversely, if it is necessary to lower the height, liquid can be injected into the cylinder 2 from the injection pipe 203 at the upper end of the cylinder 2. At this time, the liquid in the cylinder 2 below the piston disc 201 can be discharged through the injection pipe 203 at the lower end of the cylinder 2, causing the piston disc 201 to move downward and the piston rod 202 to retract, thereby lowering the height of the dust collection hood installed on the frame 3, thus meeting the dust collection requirements of different working heights.
[0025] After the height adjustment is completed, start cylinder 405. To make frame 3 rotate clockwise, inflate the rodless chamber of cylinder 405. The telescopic end of cylinder 405 will extend. At this time, the connecting rod 406, under the thrust of cylinder 405, will push the rotating shaft 402 to rotate clockwise, and frame 3 will rotate accordingly. Conversely, inflating the rod chamber of cylinder 405 will make frame 3 rotate counterclockwise, thereby adjusting the angle of the dust collection hood. This meets the dust collection requirements of different working directions, improves the applicability of the dust collection hood, and ensures efficient dust collection even under complex working conditions.
[0026] Example 2:
[0027] Reference Figure 4 A rotating support device for a dust collection hood is basically the same as that in Embodiment 1. Furthermore, a limiting groove is provided in the mounting base 4, and a rotating block 401 is rotatably connected in the limiting groove. One end of the rotating shaft 402 passing through the limiting groove is fixedly connected to the rotating block 401.
[0028] When the frame 3 is rotated via the rotating shaft 402, the rotating block 401 rotates synchronously within the limiting groove along with the rotating shaft 402, effectively enhancing the stability of the rotating shaft 402 and thus ensuring the stability of the dust collection hood installed on the frame 3 when adjusting its angle.
[0029] Example 3:
[0030] Reference Figure 4 A rotating support device for a dust collection hood is basically the same as that in Embodiment 1. Furthermore, a plurality of balls 403 are equidistantly arranged on the upper end surface of the mounting base 4, and a support ring is fixedly connected to the rotating shaft 402, with the balls 403 in contact with the support ring.
[0031] When the rotating shaft 402 rotates, the ball bearing 403 rolls below the support ring, thereby changing the original sliding friction between the rotating shaft 402 and the mounting base 4 into rolling friction, greatly reducing the friction force and making the rotation of the rotating shaft 402 smoother. At the same time, the cooperation between the ball bearing 403 and the support ring provides stable support for the rotating shaft 402, so that the rotating shaft 402 can remain stable during rotation, thereby ensuring that the frame 3 will not wobble or deviate when rotating, effectively improving the stability of the frame 3 rotation.
[0032] Example 4:
[0033] Reference Figure 1 , Figure 2 A rotating support device for a dust collection hood is basically the same as that in Embodiment 1. Furthermore, it also includes a base 1 for fixing the cylinder 2. The base 1 is fixedly connected to the lower end of the cylinder 2, and the base 1 has a mounting hole 101.
[0034] When installing the equipment, place the base 1 in the predetermined position, align the mounting hole 101 with the connection point on the foundation, insert the bolts and tighten them so that the base 1 can provide stable support for the device. This ensures that even if the device is subjected to external forces such as equipment vibration or airflow impact during the dust collection process, it can still maintain its original position without displacement or shaking, thus stably collecting dust and improving collection efficiency.
[0035] Example 5:
[0036] Reference Figure 1 A rotating support device for a dust collection hood is basically the same as in Embodiment 1. Furthermore, a dust collection chamber is provided inside the frame 3, and a plurality of dust collection ports 301 connected to the dust collection chamber are provided at equal intervals on the side wall of the frame 3. A dust collection pipe 302 connected to the dust collection chamber is provided on the frame 3.
[0037] In use, first connect the suction pipe 302 to the external exhaust device. When it is necessary to capture smoke and dust, start the exhaust device to create a negative pressure in the suction chamber. At this time, the smoke and dust can be continuously sucked in from each suction port 301, and then pumped to the subsequent dust removal equipment through the suction pipe 302 connected to the suction chamber. At the same time, the setting of multiple suction ports 301 enables comprehensive capture of smoke and dust, preventing smoke and dust from escaping, thereby maximizing the smoke and dust collection rate, effectively purifying the working environment, and protecting the health of operators.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
