Summary of the invention
For existing deficiency in the prior art, the object of the present invention is to provide and a kind ofly can realize indirectly the more air draft prefilter of the hot cell with mechanical interlock mechanism of renew cartridge with manipulator in the hot cell or crane.
The present invention solves the problems of the technologies described above the technical scheme that adopts as described below:
A kind of hot cell air draft pre-filtrating equipment with mechanical interlock mechanism, comprise bearing and discharge pipe, longitudinal framing post in the bearing both sides arranges bumping post, it is characterized in that: in the space that frame column and bumping post by bearing surround, the prefilter core body is set, the up and down both sides of bearing are connected with respectively the camshaft that be arranged in parallel with the transverse frame post, the both sides of each camshaft arrange respectively the cam with the ridge back of the body, are provided for the handle of pulling of rotating cam at an end of each camshaft.
Further, the back side of described bearing is connected with discharge pipe by sealing gasket.
Further, described prefilter core body is by adjusting the sealing between pad realization and the discharge pipe.
Further, the top of described prefilter core body arranges the suspension ring of Gong slinging.
Further, the frame column of described bearing is four.
Further again, described prefilter core body is cuboid.
Beneficial effect of the present invention is as follows: the present invention is by being arranged on the prefilter core body in the bearing, and be connected with respectively the camshaft that arranges with transverse frame post equality in the up and down both sides of bearing, the both sides of each camshaft arrange respectively the cam with the ridge back of the body, one end of each camshaft is provided for the handle of pulling of rotating cam, therefore, utilize lever and cam mechanism simple in structure just can realize the locking of prefilter core body or unclamp, just can realize the replacing of cartridge by manipulator in the hot cell or the crane prefilter core body of slinging, therefore, be a kind of simple in structure, air draft pre-filtrating equipment in the convenient and practical hot cell.

The specific embodiment
The invention provides a kind of built-in hot cell air draft prefilter with mechanical interlock mechanism.Generally can be placed on the rear wall or sidewall in the casing of hot cell, the prefilter core body is rectangle, can change by manipulator in the hot cell or crane, and by the lever and cam winding machine to the locking of prefilter core body and the sealing function between filter core body and air outlet tube mouth, prefilter of the present invention need be arranged in the opereating specification of manipulator in the hot cell or crane.
Present invention is described below in conjunction with the drawings and specific embodiments.
A kind of hot cell air draft pre-filtrating equipment with mechanical interlock mechanism, shown in Fig. 1-5, comprise bearing 1 and discharge pipe 7, bearing 1 comprises four frame columns, longitudinal framing post in bearing 1 both sides arranges bumping post 2, in the space that frame column and bumping post by bearing 1 surround, prefilter core body 3 is set, prefilter core body 3 is rectangular shape, the top of prefilter core body 3 arranges the suspension ring of Gong slinging, the up and down both sides of bearing 1 are connected with respectively the camshaft 5 that be arranged in parallel with the transverse frame post, each camshaft 5 comprises axle 10 and cam 9, the left and right sides of each axle 10 arranges respectively the cam 9 with the ridge back of the body, pulls handle 6 what an end of each axle 10 was provided for rotating cam 9.
The back side of bearing 1 is connected with discharge pipe 7 by sealing gasket 8, and prefilter core body 3 is by adjusting the sealing between pad 4 realizations and the discharge pipe 7.
In one embodiment, the present invention mainly is comprised of parts such as prefilter core body 3, bearing 1, camshaft 5, discharge pipe 7, sealing gaskets 8.Implementation procedure of the present invention is as follows: Fig. 1,2 has shown the structure of the air draft prefilter under the duty.During duty, prefilter core body 3 is fixed on the operating position by bearing 1, bumping post 2, and bearing 1 plays a supportive role, and 2 of bumping posts have limited the motion of prefilter core body 3 left and right directions.Pull handle 6 and drive camshaft 5 rotations, Fig. 3 has shown the structure of camshaft 5.Utilize the tight prefilter core body 3 of ridge back pressure of axle 10 overhead cams 9, thereby and compress 4 realizations of adjustment pad to the locking of prefilter core body 3, measure-alike to the compression on prefilter core body both sides about in the of 3 when adjusting pad 4 assurance assembling, to realize the even locking to prefilter core body 3.At this moment, air is realized filtering by prefilter core body 3 in the hot cell, and process discharge pipe 7 is discharged in the ventilation shaft, because the situation stopping up or damage may appear in prefilter core body 3, so need to carry out the periodic replacement under the accident condition, when prefilter core body 3 stops up, filter efficiency descends or filter core damages in the time of need to changing, and only need pull handle 6, rotating cam axle 5, make the ridge of axle 10 overhead cams 9 deviate from out prefilter core body 3, at this moment, prefilter core body 3 can move upward, and utilizes the operating equipments such as manipulator in the hot cell or cell crane, sling suspension ring on the prefilter core body 3 can hang away processing from the top with prefilter core body 3.In like manner, new prefilter core body can be in place by reverse motions.Prefilter core body 3 is changed structure shown in Fig. 4,5.
The present invention is by being arranged on prefilter core body 3 in the bearing 1, and be connected with respectively the camshaft 5 that be arranged in parallel with the transverse frame post in the up and down both sides of bearing 1, the both sides of each camshaft 5 arrange respectively the cam 9 with the ridge back of the body, what one end of each camshaft 5 was provided for rotating cam 9 pulls handle 6, therefore, utilize lever and cam mechanism simple in structure just can realize the locking of prefilter core body or unclamp, just can realize the replacing of prefilter core by manipulator in the hot cell or the crane prefilter core body 3 of slinging, therefore, be a kind of simple in structure, air draft pre-filtrating equipment in the convenient and practical hot cell.
It should be noted that; above-mentioned specific embodiment only is exemplary; under above-mentioned instruction of the present invention, those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment, and these improvement or distortion all drop in protection scope of the present invention.It will be understood by those skilled in the art that top specific descriptions just in order to explain purpose of the present invention, is not for restriction the present invention.Protection scope of the present invention is limited by claim and equivalent thereof.
