Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, the present utility model provides a technical solution: the utility model provides a vacuum rake dryer sealing structure, includes vacuum rake dryer feed pipe 1 and toper stopcock 4, fixedly connected with sealing ring 2 on the interior pipe wall of vacuum rake dryer feed pipe 1, and feed inlet 3 has been seted up in the top penetration of sealing ring 2, and toper stopcock 4 sets up at the interior top of vacuum rake dryer feed pipe 1, and toper stopcock 4 pegs in to the inside feed inlet 3 of sealing ring 2.

The top fixedly connected with upper shrouding 5 of toper pipe stopper 4, and upper shrouding 5 and the interior pipe wall contact of vacuum rake dryer feed cylinder inlet pipe 1, upper shrouding 5 can further make the sealed effect improvement of toper pipe stopper 4.

The bottom fixedly connected with spring 6 of last shrouding 5, the other end fixedly connected with holding ring 7 of spring 6, the elasticity of the spring 6 at holding ring 7 top can promote to go up shrouding 5 and toper tube plug 4 and restore to the throne, and toper tube plug 4 and last shrouding 5 of being convenient for take out.

The feed inlet 3 and the conical tube plug 4 are matched, and the funnel-shaped feed inlet 3 matched with the conical tube plug 4 can be fully matched and sealed with the conical tube plug 4.

The conical pipe plug 4 is made of an insulating rubber material, and the conical pipe plug 4 made of the insulating rubber material can deform, so that the sealing performance between the conical pipe plug 4 and the sealing ring 2 is better.

Specifically, communicate vacuum rake dryer feed pipe 1 with the feed cylinder of vacuum rake dryer, when using, pull out last shrouding 5 and toper tube plug 4 outwards, can carry the material to the inside of feed cylinder through the feed inlet 3 on the sealing ring 2 through vacuum rake dryer feed pipe 1, when needs seal vacuum rake dryer feed pipe 1, insert the inside of vacuum rake dryer feed pipe 1 with last shrouding 5, the toper tube plug 4 of going up shrouding 5 bottom will peg graft in the feed inlet 3 on the sealing ring 2 and block up, in the in-process of suction and discharge at the vacuum rake dryer feed cylinder, because the inside of feed cylinder is negative pressure state, atmospheric pressure can promote toper tube plug 4 towards the inside of sealing ring 2, thereby make toper tube plug 4 carry out stable sealing to the feed inlet 3 on the sealing ring 2.
