Description

Technical Field

[0001] The invention relates to the technical field of ventilators, and in particular to an assembly structure of a ventilator collector and a casing. Background Art

[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Modern fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings. Through the fan collector, the dispersed airflow can be concentrated and directed to the fan, thereby improving the fan's suction efficiency and thus improving the overall performance of the ventilation system.

[0003] At present, most domestic manufacturers produce centrifugal fans. The assembly method of the collector and the casing is to drill holes in the casing and then match the collector and the casing. However, during processing, the cost of drilling holes is high and the efficiency is low. The two workpieces need to be clamped and fixed on a drilling machine for connecting holes. The process is cumbersome, especially for the transportation of large fans. Since the workpieces are large, clamping is more difficult, which affects the overall production efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an assembly structure of a ventilator collector and a casing is proposed. Summary of the invention

The end of the sliding column is fixed with a limiting ring, and the inner sliding connection of the limiting ring is connected to the limiting column, and the limiting column is fixedly connected to the collector flange.

[0012] Furthermore, a locking assembly is provided in the middle of the protective cover, and the locking assembly includes a sealing plate, a magnet and a pressure block.

The upper and lower ends of one side of the protective cover are provided with reset grooves, and the width of the reset groove is equal to the width of the limit block.

[0016] The present invention provides an assembly structure of a ventilator collector and a casing, which has the following beneficial effects:

[0017] 1. The present invention utilizes the positioning hole to initially limit the thick nut, and performs welding operation at the first welding portion to fix the thick nut on the reinforcement ring. After that, the reinforcement ring only needs to be welded to the front side plate of the casing to replace the traditional thread hole. Therefore, there is no need to open high-precision thread holes on the larger front side plate of the casing, thereby reducing processing costs. In addition, by opening a large hole on the collector flange and using hexagonal bolts to squeeze the connecting seat under the limit of the thick nut during assembly, the collector flange and the front side plate of the casing are pressed and fixed. At this time, the larger hole has a certain fine-tuning range during assembly, which can solve the problem of position error caused by the connection hole not being matched for processing. Therefore, during the processing, there is no need to clamp the larger shell together for matching drilling, which greatly simplifies the manufacturing process and saves the time for transporting large workpieces back and forth and the cumbersome process of clamping.

[0018] 2. When the bolt head is pressed against the connecting seat, the rubber pad will be in close contact with the collector flange to enhance the friction between them and prevent the connecting seat from rotating. After tightening the hexagonal bolt, the protective cover can be closed. At this time, the protective cover is used to cover and protect the bolt head, and moisture-absorbing cotton is used to keep the space around the bolt head dry to prevent the bolt head from rusting and affecting the efficiency of subsequent disassembly and maintenance. When positioning the protective cover, it is only necessary to move the limit plate upward to avoid the convex strip first. After the protective cover is fitted with the connecting seat, the limit plate is moved downward to make the slider slide in the guide groove, and the limit plate can be used to block the convex strip, thereby quickly fixing the protective cover, and the magnetic stopper can absorb the slider to position the limit plate. When disassembly and maintenance are required, it is only necessary to move the limit plate upward to quickly release the restriction on the protective cover, making it convenient and quick to use.

[0019] 3. Before closing the protective cover, the present invention first moves the pressing block upward, and when the protective cover is closed, the pressing block is pressed downward, and the magnet will absorb the convex plate to quickly fix the pressing block. In this process, the pressing block can squeeze the inclined surface of the top plate, which can drive the first end gear plate to move toward the second end gear plate on the hexagonal bolt, and plug and engage with each other, and the fixing ring will limit the movement of the limit block, which can limit the rotation of the first end gear plate, so that the hexagonal bolt on the second end gear plate can be limited, so as to avoid the hexagonal bolt from easily rotating and loosening in a vibration environment, and further improve the stability of the fan collector and the casing after assembly At the same time, the width of the limit groove is slightly larger than the width of the limit block, so that the side ring has a certain micro-rotation space, so that when the first-end gear disc and the second-end gear disc are plugged in, the first-end gear disc can rotate slightly and automatically adjust the tooth position to avoid jamming during plugging in. When disassembling and maintaining, you only need to move the pressure block upward. At this time, the magnet can absorb the iron top plate, which can drive the first-end gear disc to separate from the second-end gear disc. At this time, the side edge of the reset groove has a certain chamfer, which can guide the limit block, so that the first-end gear disc that has been slightly rotated before can be rotated and reset, so that it can be reused in subsequent plugging.

[0020] 4. In the present invention, since the limit column is welded to the collector flange in advance, during assembly, by inserting the limit ring on the limit column, the sliding column can lock the rotation angle of the connecting seat, thereby preventing the connecting seat from rotating together with the hexagonal bolt in a vibration environment and causing loosening. At the same time, the sliding column can slide in the sliding groove, so it can automatically adapt to the different spacings between the limit column and the large hole, so that a larger error range is allowed when welding the limit column, thereby improving the efficiency during processing, and the sliding column and the connecting seat can only be separated after the fixing block slides to the other end along the tortuous anti-slip groove. Therefore, after the connecting seat and the sliding column are assembled and transported, the accidental falling of the smaller sliding column is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, after the connecting seat 1201 and the sliding column 1303 are assembled and transported, the accidental falling of the smaller sliding column 1303 is reduced. Then, the connecting seat 1201, the collector flange 1, the sealing ring 3, the front side plate 4 of the casing, and the reinforcing ring 6 are connected and fixed by the hexagonal bolts 9 and the thick nuts 8.

At the same time, the width of the limiting groove 1411 is slightly larger than the width of the limit block 1409, so that the side ring 1408 has a certain micro-rotation space, so that when the first end toothed disc 1406 and the second end toothed disc 1407 are plugged in, the first end toothed disc 1406 can rotate slightly and automatically adjust the tooth position. Finally,During disassembly and maintenance, it is only necessary to move the pressing block 1403 upwards, and the magnet 1402 can then absorb the iron top plate 1405, and drive the first end toothed disc 1406 to separate from the second end toothed disc 1407.
