Abstract
The utility model relates to a trolley furnace sand sealing device, which comprises a trolley body, a sand sealing groove and a sand sealing knife. The utility model is characterized in that the annular sand sealing groove is arranged on the trolley body; the sand sealing knife is fixed on a trolley; a three-dimensional space guiding device (a reciprocating motion guiding device, a traction device, and a vertical guiding device) is connected to the annular sand sealing groove; a double-sealing structure of the whole trolley is formed by labyrinth seal composed of a trolley frame on the upper part matched with the annular sand sealing groove and a furnace wall. The utility model has the advantages that ascension and descent of the sand sealing groove are realized by the trolley entering the furnace and getting out of the furnace without any other power mechanism, the leakage loss of sand can be reduced, sealing sand can be added on the outside of the furnace at any time, the sealing effect is increased, driving mechanisms for ascension and descent of the sand sealing groove are removed, the structure is reliable and simple, frequent furnace charging and tapping requirements are satisfied, and the development of the trolley furnace sand sealing device provides an ideal sand sealing system for high-temperature trolley type furnaces.
Description
Technical field:
The utility model relates to car-type and adds a kind of device of pining for, particularly car type furnace sand seal device.
Background technology:
At present, the sand seal device of domestic car type furnace is that sand sealing knife is fixed on the chassis, and sand sealing groove is fixed on the stove side wall.There is following defective in this structure: 1, when chassis turnover stove, the sand sealing knife level breaks away from or inserts in the interior sealing sand of seal groove, and sealing sand is very easily taken out of by sand sealing knife, along with the frequent material that takes on, sand reduces gradually in the seal groove, can not reach sealing effectiveness.2, because sand sealing groove owing to be fixed in the stove, unless temperature drops to normal temperature in the stove, otherwise can not realize formerly safeguarding filling sealing sand.3, owing to the ring packing that can not realize chassis, so sealing effectiveness is poor, causes the pallet bottom temperature too high, causes the too early damage of pallet bottom drive disk assembly.
Though the domestic mechanism that also has sand sealing groove to rise and to descend must be provided with the driving mechanism that a cover is used for the sand sealing groove lifting simultaneously, this mechanism in use very easily damages and complex structure, and it is unreliable to move.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and a kind of car type furnace sand seal device, simple in structure, easy to maintenance, the long service life of this device are provided.
The technical solution of the utility model is: a kind of car type furnace sand seal device, comprise chassis body, sand sealing groove and sand sealing knife, it is characterized in that: the chassis body is provided with the ring-shaped sand sealing groove, sand sealing knife is fixed on the chassis, connect three dimensions guider one seesaw guider, draw-gear and vertically-guided device on the ring-shaped sand sealing groove, the chassis frame that the ring-shaped sand sealing groove cooperates top and the labyrinth sealing of furnace wall formation form the double sealing structure of whole chassis.
The described guider that seesaws is made up of directive wheel and the guide rail that has the slope shape track.
The traction track composition that described draw-gear is served as reasons and is installed in the draw bar on the ring-shaped sand sealing groove and is installed in the draw bar both sides.
Described vertically-guided device is made up of with the vertically-guided track that is installed in its both sides the guide post that moves both vertically that is installed on the ring-shaped sand sealing groove.
The utility model has the advantages that: this device can pass in and out stove and not need to add in addition rising and the decline that actuating unit is realized sand sealing groove with chassis, both can reduce the leakage loss of sand, can outside stove, add sealing sand at any time again, improve sealing effectiveness, removed the driving mechanism that sand sealing groove rises and descends, simple and reliable for structure, be fit to frequently take on the requirement of stove.Its middle high temperature bench vehicle type stove that is developed as provides a cover desirable sand seal system.

The specific embodiment:
As shown in the figure: a kind of car type furnace sand seal device, comprise ring-shaped sand sealing groove 1 and the sand sealing knife 5 that is fixed on the chassis 4, it is characterized in that: connect three dimensions guider one seesaw guider, draw-gear and vertically-guided device on the ring-shaped sand sealing groove, the labyrinth sealing that the chassis frame on ring-shaped sand sealing groove cooperation top and furnace wall constitute forms the double sealing structure 11 of whole chassis, and the described guider that seesaws is made up of directive wheel 2 and the guide rail 3 that has the slope shape track.Traction track 8 compositions that described draw-gear is served as reasons and is installed in the draw bar 7 on the ring-shaped sand sealing groove and is installed in the draw bar both sides.Described vertically-guided device is made up of with the vertically-guided track 10 that is installed in its both sides the guide post 9 that moves both vertically that is installed on the ring-shaped sand sealing groove.
The course of work of the present utility model is: when the operation of chassis turnover stove, parts 8 drive about parts 7 and full annular sand seal device and move, parts 2 are along the slope shape track operation of parts 3, so that whole sand sealing groove rises gradually and descends, contact sealing with sand sealing knife or break away from sealing.Sand sealing groove vertically-guided device makes sand sealing groove and chassis keep the relative positioning invariant position.The ring-shaped sand sealing groove cooperates the chassis frame on top and the labyrinth sealing that furnace wall constitutes, and forms the double sealing structure of whole chassis, reduces the environment temperature of pallet bottom greatly, has prolonged the service life of pallet bottom drive disk assembly and frame greatly.Reduce heat exhaustion, saved the energy.
