Detailed Description

The invention will be explained in more detail by the following examples, which disclose the invention and are intended to protect all technical improvements within the scope of the invention.

Combine attached figure 1, fig. 2, a vacuum rapid hardening stove secondary feeding device, including detacher 5, feed cylinder 4 and collet 6, open hollow structure of lower extreme about feed cylinder 4 is, collet 6 sets up in the lower port department of feed cylinder 4 and is located the inside of feed cylinder 4, is connected through detacher 5 between collet 6 and the feed cylinder 4, is provided with a plurality of stabilizer blades 7 on the lower bottom surface of collet 6 to the lower tip of stabilizer blade 7 stretches out feed cylinder 4.

Detacher 5 sets up on the lateral wall of port under feed cylinder 4 along the circumferencial direction equipartition, detacher 5 includes fixed block 51 and dog 52, and fixed block 51 is the structure of falling the U-shaped that comprises roof and the curb plate of connection in the roof left and right sides, is provided with limiting plate 53 on the downside of roof to limiting plate 53's length is less than the length of curb plate, is provided with round pin axle 54 between the board of both sides, dog 52 is through the through-hole pin joint on it in round pin axle 54, and the through-hole on the dog 52 is located the inboard at dog 52 center, and the inboard end top of dog 52 pastes on collet 6 downside, and the outside top of dog 52 pastes on limiting plate 53 downside.

In the utility model, because the stopper 52 is pivoted on the pin 54, the stopper 52 can rotate on the pin 54, after the material cylinder 4 is filled with the material, the bottom support 6 moves downwards, the inner side end of the stopper 52 is pressed downwards, the outer side end of the stopper 52 is lifted upwards, the outer side end of the stopper 52 cannot rotate due to the limit of the limit plate 53, and at the moment, the bottom support 6 is supported by the inner side end of the stopper 52; when the charging barrel 4 moves to the smelting device, the support legs on the bottom support 6 firstly contact the smelting device, then the charging barrel 4 is continuously lowered, the inner side end of the stop block 52 is separated from the bottom support 6, the bottom support 6 is thrown into the smelting device along with materials in the charging barrel 4, the outer side end of the stop block 52 moves downwards through the lever principle, the inner side end of the stop block 52 moves upwards, and finally the stop block 52 is in a vertical state.

It should be noted that, if the bottom support 6 is put along with the material, the material of the bottom support 6 is the same as the material; if the bottom support is not put into the smelting device, the charging barrel is connected with the bottom support through a rope chain.

In addition, the collet 6 is circular, and the diameter of collet 6 and the internal diameter looks adaptation of feed cylinder to after making the material pack into the feed cylinder, can not leak down in the gap between collet and the feed cylinder.

In practical application, the charging barrel 4 is hoisted by the lifting device, so as to be the preferred scheme, a plurality of pull ropes 3 are uniformly distributed on the outer side surface of the upper port of the charging barrel 4 along the circumferential direction, the upper ends of the pull ropes 3 are connected to the lower bottom surface of the lower connecting plate 8, and the lower connecting plate 8 is connected with the upper connecting plate 2 through the unhooking device 5; the center of the upper surface of the upper connecting plate 2 is provided with a lifting rod 1, the lifting rod 1 is connected with a lifting device, and the lifting device can adopt equipment such as a crown block, an electric hoist and the like.

The utility model discloses can accomplish the back at last technology, carry out the material loading under vacuum and high temperature environment, because last process flow has just been accomplished, do not release the vacuum and open the furnace gate, stove and smelter still have very high waste heat, accomplish the loading of next heat material in this time, can not only reach the vacuum requirement that the technology needs very fast, waste heat also can reduce the heat time of material, need not reduce the furnace temperature like before, open the furnace gate after the release vacuum and carrying out the loading of next heat material, very big improvement production efficiency, and effectively reduce the production energy consumption.
