SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the shortcoming among the prior art, provide a drying cylinder with clean hole.

In order to achieve the above purpose, the utility model adopts the technical scheme that:

a drying tank structure with cleaning holes comprises a drying tank body, a drying tank flange welded above the drying tank body and a drying tank cover arranged above the drying tank flange; a threaded hole which is not communicated with the drying tank flange is vertically formed in the drying tank flange and is communicated with the drying tank cover; a cleaning hole communicated with the outer wall of the drying tank flange is formed inside and outside below the threaded hole; the bottom of the cleaning hole is positioned above the bottom surface of the drying tank flange.

The included angle between the central axis of the cleaning hole and the central axis of the threaded hole is an angle alpha formed by the cleaning hole, and the alpha is more than 90 degrees and less than or equal to 150 degrees.

And a sealing ring is arranged on the contact surface of the drying tank flange and the drying tank cover.

The drying tank cover is provided with a vacuum hole which penetrates through the drying tank cover.

The number of the threaded holes is 6.

The contact part of the outer wall of the drying tank flange and the upper part of the cleaning hole is set to be a round angle.

Compared with the prior art, the beneficial effects of the utility model are that:

according to the technical scheme, the cleaning holes are formed below the bolt holes, foreign matters are discharged after the cleaning holes are formed, so that the direct sealing performance of the drying tank flange and the drying tank cover is enhanced, the product yield in the drying tank body is high, and the comprehensive production cost is low;

the drying tank flange and the drying tank cover can be repeatedly detached; after the drying tank flange and the drying tank cover are tightly pressed, even if the drying tank is baked at high temperature for a long time or is in a repeated heating and cooling process, the inner cavity still can be kept sealed when bearing vacuum or positive pressure.

The utility model discloses a be applicable to large batch production mode, the product of production can satisfy the application requirement in fields such as transportation, aviation, can satisfy people to the high reliability of article such as lithium cell and ultracapacitor system, and low-cost needs are favorable to popularizing extensively, have great production practice meaning.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

Fig. 1-3 show a drying cylinder structure provided with cleaning holes, comprising a drying cylinder body 2, a drying cylinder flange 1 welded above said drying cylinder body, and a drying cylinder cover 3 arranged above said drying cylinder flange; a threaded hole 101 which is not communicated with the drying cylinder flange is vertically formed in the drying cylinder flange and is communicated with the drying cylinder cover; a cleaning hole 102 communicated with the outer wall of the drying tank flange is formed inside and outside below the threaded hole; the bottom of the cleaning hole is located above the bottom surface of the drying cylinder flange, and the threaded hole 101 cannot penetrate through the bottom of the drying cylinder flange 1, so that leakage between the upper surface and the lower surface of the drying cylinder flange 1 is prevented. Likewise, the cleaning holes do not extend through the bottom of the canister flange.

An included angle 106 between the central axis 104 of the cleaning hole and the central axis 105 of the threaded hole is an angle alpha formed by the cleaning hole, and alpha is more than 90 degrees and less than or equal to 150 degrees. The cleaning hole 102 is used for cleaning foreign matters at the bottom of the screw hole 101. When the cleaning hole opening angle 106 between the cleaning hole central axis 104 and the threaded hole central axis 105 is larger than 90 degrees, the foreign matter 6 at the bottom of the threaded hole 101 can naturally fall off, the effect of preventing the foreign matter at the bottom of the threaded hole 101 from remaining is achieved, and the error-proofing capability of the sealing structure is improved.

And a sealing ring is arranged on the contact surface of the drying tank flange and the drying tank cover. The upper surface of the drying tank flange 1 and the lower surface of the drying tank cover 3 are sealed by the sealing ring 4 without leakage.

The drying tank cover is provided with a vacuum hole which is communicated with the drying tank cover. The vacuum hole 301 is used to vacuumize the cavity between the upper surface of the canister flange 1 and the lower surface of the canister cover 3. The drying cylinder flange 1 and the drying cylinder cover 3 can be repeatedly detached, and after the drying cylinder flange 1 and the drying cylinder cover 3 are tightly pressed, the sealing can still be kept when the inner cavity bears vacuum or positive pressure even if the inner cavity is baked at high temperature for a long time or is in a repeated heating and cooling process.

The number of the threaded holes is 6. 6

bolts

5 and 6 screw holes 101 cooperate, compress tightly the drying cylinder lid 3 and fix on the drying cylinder flange 1. The side wall of the cleaning hole 102 is smooth and has low roughness; the contact position of the outer wall of the drying tank flange and the upper part of the cleaning hole is set to be a round angle 103, the surface of the round angle 105 is smooth, and no rough edges or burrs exist. The cleaning hole outside fillet 103 is used for reducing the risk of being scratched and clamped by personnel operation and improving the safety.

It should be noted that, if the threaded hole 101 is a blind hole, when the foreign object 6 is present at the bottom of the threaded hole 101, referring to fig. 4 (without the example of cleaning hole), the foreign object 6 cannot move downward, so that the lid 3 of the drying cylinder cannot press the flange 1 and the sealing ring 4 of the drying cylinder, resulting in leakage. For this reason, need improve this structural defect and obtain the technical scheme of this application, the utility model discloses a clean hole 102 discharge foreign matter, bolt 5 and screw hole 101 cooperation make retort lid 3 and retort flange 1 extrude sealing washer 4 jointly and reach seal structure.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
