Utility model content
For solving to adopt in bucket in the radwaste cement solidification line of curing process material by feeder apparatus to the addition problem of pail for used dressings, it is achieved the filling of pail for used dressings dry material, this utility model provides a kind of siccative for cement solidification and fills cover。
This siccative filling cover includes cover cylinder, cement feed pipe, filter and blower fan；Described cover cylinder is the cylinder of both ends open, and its edges at two ends place is respectively equipped with sealing ring and lower seal, and cover drum outer wall is provided with proximity switch and additive feed pipe；Described additive feed pipe is provided with additive and purges interface；Described cement feed pipe one end is connected on cover drum outer wall, and is connected with inside cover cylinder, and the other end is closed；The sidewall of cement feed pipe is provided with cement charging aperture vertically upward, is provided with cement and purges interface near cement charging aperture；The outer wall of cement feed pipe is provided with vibrating motor；The entrance point of described filter is connected with inside cover cylinder by filter adapter, and the port of export is connected with the air inlet of described blower fan by blower fan adapter。
It is preferred that described filter top is provided with compression gas interface, compresses the gas interface opening in filter interior towards the filter material of filter。
It is preferred for being provided with differential pressure transmitter between the adapter of described filter and blower fan adapter。
It is preferred that the outer wall of described cement feed pipe is provided with heat tape。
It is preferred that the outer wall of described filter adapter is provided with heat tape。
Siccative of the present utility model filling cover belongs to a kind of interface equipment。In pail for used dressings dry material filling process, owing to needing that the dry material of the radioactive liquid waste in pail for used dressings and addition is stirred, therefore siccative filling cover body adopts tubular design (namely covering cylinder), mixing plant contacts through cover cylinder and with the sealing of upper sealing ring, the lower seal of pail for used dressings and cover cylinder seals and contact, it is achieved thereby that being tightly connected of feeder apparatus and pail for used dressings。Additive feed pipe is easy to the addition of additive, is conducive to improving cement solidification effect；Designed additive purges interface and is easy to adopt gas that the additive being attached on additive feed pipe inwall is purged, it is ensured that additive amount accurate。
The vibrating motor arranged on cement feed pipe outer wall ensure that the smooth filling of dry material, it is to avoid the problem such as incidental blocking under super-humid conditions in pail for used dressings；The cement that cement charging aperture is arranged around purges interface and also allows for carrying out inside cement feed pipe purging cleaning。
The dust pelletizing system being made up of filter and blower fan of described employing effectively eliminates the high-concentration dry material dust in pail for used dressings internal upper part space, solves airborne dust problem when siccative filling cover separates with pail for used dressings, is conducive to being smoothed out of dry material filling operation。
After siccative filling cover often runs a period of time, it is possible to introduce one compression gas by compressing gas interface, the cement built up in the filter is carried out blowback, it is ensured that the filter effect of filter, extend the use time of filter。
The differential pressure transmitter adopted can take over the draught head between blower fan adapter by monitor filter, stops the operating of blower fan when draught head is too high, to realize the protection of filter and adapter。
The heat tape arranged on described cement feed pipe and filter adapter outer wall can prevent the bonding of moist cement preferably, it is ensured that it is properly functioning for a long time that siccative filling is covered。
In sum, siccative for cement solidification of the present utility model fills cover and is capable of sealing and the smooth filling of pail for used dressings dry material under stirring condition, filling operation is relatively simple, efficiently solve the problem such as incidental blocking, bonding under super-humid conditions, facilitate implementation the remote-controlled operation of filling process, meet radiation safety and reliability of technology requirement preferably。
