[0037] Example

[0038] The safe and reliable new type of insulated barrel structure provided in this embodiment, such as Figures 1-5 As shown, it includes: a heat-insulating barrel body 1, which includes two connected heat-insulating barrel sections 101. The bottom of the lower heat-insulating barrel section 101 is directly connected to the upper part of the dust collector body 2. Annular connecting plates 102 are fixedly installed on the bottom periphery of the upper heat-insulating barrel section 101, the two ends periphery of the lower heat-insulating barrel section 101, and the upper periphery of the dust collector body 2. The annular connecting plate 102 on the bottom periphery of the upper heat-insulating barrel section 101 is fixedly connected to the annular connecting plate 102 on the upper periphery of the lower heat-insulating barrel section 101 by bolts 3. The annular connecting plate 102 on the bottom periphery of the lower heat-insulating barrel section 101 is fixedly connected to the annular connecting plate 102 on the upper periphery of the dust collector body 2 by bolts 3.

[0039] Among them, the lower section of the insulated barrel 101 has an integrally formed an outwardly protruding annular heating pipe mounting groove 107 on its barrel wall, and the distance between the bottom of the annular heating pipe mounting groove 107 and the bottom of the lower section of the insulated barrel 101 is 100mm.

[0040] The new type of heat preservation barrel structure with the above technical solution is safe and reliable. The bottom of the heat preservation barrel body 1 is directly connected to the upper part of the dust collector body 2. This is equivalent to connecting the heating tube shell to the ground, realizing reliable grounding, and keeping it away from the cathode high voltage. This can avoid the transmission of high voltage to the dust removal low voltage power distribution system, thereby avoiding the adverse situation of frequent tripping or damage to low voltage components.

[0041] The annular heating tube mounting groove 107 is specifically designed for installing heating tubes, making it easy to observe whether there are burn marks, cracks, etc. on the surface of the heating tube. This can significantly shorten the amount of high-temperature resistant cable required for the heating tube terminals, effectively reducing costs.

[0042] Specifically, in this embodiment, in order to avoid the size of the annular heating tube mounting groove 107 from adversely affecting the arrangement of the insulation bucket on the top of the existing dust collector, the annular heating tube mounting groove 107 is provided with an outward protrusion depth of 75mm, an internal height of 142mm, and an external height of 150mm.

[0043] Specifically, in this embodiment, to prevent the bolt 3 from loosening due to vibrations generated during the operation of the dust collector body 2, the bolt 3 includes a bolt head 301, a screw 302, a nut 303, and a washer 304. The screw 302 is fixedly installed on one side of the bolt head 301, the nut 303 is threaded onto the screw 302, and the washer 304 is movably fitted onto the screw 302. Both sides of the washer 304 are integrally provided with several protrusions 306. The washer 304 is set close to the nut 303 and is located between the nut 303 and the bolt head 301. The several protrusions 306 can increase the static friction between the washer and the nut 303, and at the same time, the several protrusions 306 can increase the static friction between the washer and the annular connecting disc 102, thereby reducing the risk that the bolt 3 may loosen due to vibrations generated during the operation of the dust collector body 2.

[0044] Specifically, in this embodiment, in order to further improve the loosening performance of the bolt 3, a circular boss 305 is integrally provided on the side of the bolt head 301 facing the screw 302, and a number of anti-slip grooves are provided on the side of the circular boss 305 facing away from the bolt head 301. The number of anti-slip grooves can increase the static friction between the bolt head 301 and the annular connecting disc 102, thereby further improving the loosening performance of the bolt 3.

[0046] To facilitate observation of the internal condition of the insulation tank 101, especially the condition of the heating tube inside the insulation tank 101, observation ports 104 are provided on the walls of both the upper and lower sections of the insulation tank 101. A removable transparent cover 105 is installed on the outside of the observation port 104. The transparent cover 105 can be made of plexiglass, allowing for easy observation of the internal condition of the insulation tank 101 through the transparent cover 105.

[0047] In order to improve the sealing between the transparent cover 105 and the observation port 104, an annular fitting groove 108 is fixedly installed on the outer wall of the observation port 104, and a sealing ring 109 is fixedly installed on the edge of the transparent cover 105 and inserted into the interior of the annular fitting groove 108.

[0048] To facilitate handling the transparent cover 105, a handle 106 is fixedly installed on the outer side of the transparent cover 105.

[0049] In summary, the safe and reliable novel insulated bucket structure provided in this embodiment has the following advantages:

[0050] This safe and reliable new type of heat preservation barrel structure connects the bottom of the heat preservation barrel body 1 directly to the upper part of the dust collector body 2. This is equivalent to connecting the heating tube shell to the ground, achieving reliable grounding, and keeping it away from the cathode high voltage. This can avoid high voltage transmission to the dust removal low voltage power distribution system, thereby avoiding the occurrence of frequent tripping or damage to low voltage components.

[0051] The annular heating tube mounting groove 107 is specifically designed for installing heating tubes, making it easy to observe whether there are burn marks, cracks, etc. on the surface of the heating tube. This can significantly shorten the amount of high-temperature resistant cable required for the heating tube terminals, effectively reducing costs.

[0052] When in use, the heating tube is installed in the annular heating tube mounting groove 107, and the annular connecting plate 102 at the bottom periphery of the lower section of the heat preservation barrel 101 is fixedly connected to the annular connecting plate 102 at the upper periphery of the dust collector body 2 by bolts 3, and then it can be put into use.

[0053] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
