Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the following description will be made in detail with reference to the technical solutions in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.
In connection with the preferred embodiment of the present utility model shown in fig. 1-5, a sealing structure of a dust collector is provided at an opening 101 of the dust collector 100 for closing the opening 101.
In order to be able to apply the sealing structure according to the present utility model, the inner wall of the opening 101 of the dust collector 100 to which the sealing structure is applied is stepped to form at least one sealing step 102, and a plurality of inner cover fixing bolts 103 are provided on the sealing step 102, and of course, a plurality of screw holes may be provided on the sealing step 102, and when in use, the inner cover is fixed on the sealing step 102 by the inner cover fixing bolts 103 and the screw holes rotated into.
Further, the sealing structure includes at least one layer of inner cap 200 and one layer of outer cap 300, the specific number of layers can be selected according to the actual situation of the dust collector, the outer cap 300 is fixed at the end of the opening 101 by fastening bolts, the end of the opening 101 is sealed, the inner cap 200 is fastened and arranged in the opening 101 inside the outer cap 300 by bolts (i.e. the inner cap fixing bolts 103 described above) to form a sealing layer inside the opening 101, and at least one layer of silicate board 400 is further arranged between the inner cap 200 and the outer cap 300, for blocking heat transfer between the inner cap 200 and the outer cap 300. As for the number of layers of the silicate plate 400, one layer, two sides, etc. may be selected in practical applications, and specifically, the number of layers is selected according to the gap between the inner lid 200 and the outer lid 300 and the internal operation temperature of the dust remover 100. Of course, the silicate board can also be replaced by other heat insulation materials, such as heat insulation cotton, heat insulation bricks and the like according to actual conditions.
In order to ensure that the silicate board can completely fill the gap between the inner cover and the outer cover, the thickness of the silicate board is at least equal to the distance from the inner cover to the opening, or slightly greater than the distance, and the distance is controlled within 0.5mm, so that the problem that the outer cover cannot be completely attached to the opening end of the dust remover due to the fact that the silicate board is too thick is avoided.
The outer cover 300 is provided with a plurality of through holes 301 along the edge of the outer cover 300, and the through holes 301 are used for the bolts to pass through so as to fix the outer cover 300 by the bolts.
Specifically, as shown in fig. 1, fixing bolts for fixing the outer cover are provided around the outside of the opening 101 of the dust collector 100, or screw holes for fitting the bolts of the fixing outer cover 300 are provided on the outer wall of the dust collector around the outside of the opening 101 of the dust collector 100.
Further, as shown in fig. 1 and 3, as an embodiment of the present utility model, a fixing boss 201 matching with the sealing step 102 is formed at the edge of the inner cap 200, and a plurality of fixing holes 2011 matching with the fixing bolts of the inner cap 200 are formed on the fixing boss 201, and in use, the fixing bolts 103 of the inner cap on the sealing step 102 are inserted into the corresponding fixing holes 2011 on the fixing boss 201 of the inner cap 200 and fastened by nuts.
Further, as a specific embodiment of the present utility model, the polyurethane foaming agent 500 is filled between the inner cap fixing boss 201 and the silicate plate 400 to prevent the gap between the inner cap 200 and the silicate plate 400 from being corroded by dew condensation on the inner cap 200 and the inner cap fixing bolt 103.
It should be noted that the polyurethane foaming agent 500 completely covers the bolts for fixing the inner cap 200 exposed above the fixing boss 201 to block the exposed bolts from contacting with air.
In order to further enhance the tightness of the sealing mechanism, a sealing strip is arranged between the outer cover 300 and the opening 101 end of the dust remover 100, a sealing strip is arranged between the inner cover 200 and the sealing step 102, and the sealing strip is made of a high temperature resistant material, so that the sealing ring is prevented from being damaged by high temperature due to temperature rise when the dust remover operates, the service life of the sealing ring is reduced, and frequent shutdown maintenance is required.
The installation method of the utility model is as follows:
1. Preventing the inner cap 200 from being mounted on the sealing step 102 such that the inner cap fixing bolts 103 of the sealing step 102 are inserted into the corresponding fixing holes 2011 of the fixing boss 201 of the inner cap 200 and fastened by nuts;
2. Filling polyurethane foaming agent 500 between the outer side wall of the inner cover 200 and the inner side wall of the opening 101, and cutting off redundant parts after the polyurethane foaming agent 500 is formed;
3. Placing the silicate plate 400 outside the inner cover;
4. The outer cap 300 is placed at the outer end of the opening 101 of the dust collector 100 such that the through holes 301 on the outer cap 300 correspond to the bolts outside the opening 101 of the dust collector 100, or such that the through holes 301 on the outer cap 300 correspond to the screw holes on the outer wall of the dust collector around the outside of the opening 101, and the outer cap 300 is fixed outside the opening 101 by the bolts.
