Abstract
The utility model relates to a sand sealing device for a trolley furnace, which comprises a trolley steel structure, a sand sealing groove and a sand sealing knife. The utility model is characterized in that the utility model is composed of an annular sand sealing groove arranged on the trolley steel structure, a horizontal pushing device arranged at the bottom part of the annular sand sealing groove, a descending device of the annular sand sealing groove and a supporting device of the annular sand sealing groove. The utility model has the advantages that the sand sealing device can ensure that the sand sealing groove and the sand sealing knife can realize lifting type seal and disengagement as the trolley entering and getting out of the furnace without any driving mechanism, leakage loss of the sand can be effectively reduced, sealing effect of the whole body is increased, the structure is simple and reliable, the cost is low, the service life is long, and the utility model is especially suitable for trolley furnaces that annealing cycle is long, the trolley has no need to enter the furnace and get out of the furnace frequently and the furnace temperature is low.
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 is provided, and the overall tightness of this device is strong, simple in structure, easy to maintenance, long service life.
The technical solution of the utility model is: a kind of car type furnace sand seal device, comprise chassis steel construction, sand sealing groove and sand sealing knife, it is characterized in that: boost device, ring-shaped sand sealing groove lowering means and ring-shaped sand sealing groove bracing or strutting arrangement by the level that is arranged on ring-shaped sand sealing groove on the chassis steel construction, is installed in ring-shaped sand sealing groove bottom and form.
Described ring-shaped sand sealing groove lowering means is made up of crank connecting rod apparatus and coupled jointed shaft.
Described level boosts device and is made up of directive wheel and chassis framework.
Described ring-shaped sand sealing groove bracing or strutting arrangement adopts support bar.
The utility model has the advantages that: 1, this device does not add driving mechanism and can guarantee to realize the lift sealing when sand sealing groove and sand sealing knife are come in and gone out stove with chassis and break away from, and can effectively reduce the leakage loss of sand, improves integral sealing effect.2, simple and reliable for structure, cost is low, long service life.It is long to be particularly suitable for the annealing cycle, and chassis does not need frequently to pass in and out stove, and furnace temperature is the car type furnace of middle low temperature.
Description of drawings:
Fig. 1 is a front view of the present utility model
Fig. 2 is a vertical view of the present utility model
Fig. 3 is the A-A profile of Fig. 1
The specific embodiment:
As shown in the figure; A kind of car type furnace sand seal device boosts device, ring-shaped sand sealing groove lowering means and ring-shaped sand sealing groove bracing or strutting arrangement by the level that is arranged on ring-shaped sand sealing groove 1, sand sealing knife 7 on the chassis steel construction, is installed in ring-shaped sand sealing groove bottom and forms.Described ring-shaped sand sealing groove lowering means is made up of crank connecting rod apparatus 3 and coupled jointed shaft 4.Described level boosts device and is made up of directive wheel 6 and chassis framework 2.Described ring-shaped sand sealing groove bracing or strutting arrangement adopts support bar 5.
Drive the sand sealing groove level and boost device 6 promotion full annular sand seal grooves 1 when chassis turnover stove level run enters in the stove, and make it to raise rise, fixing sand sealing knife 7 is inserted in the sand sealing grooves, the sand sealing realizes going in ring.The sand sealing groove level boosts the belt seal groove of device 6 disengagings when chassis turnover stove level run withdraws from outside the stove, the sealing device that goes in ring simultaneously connects by the crank load by deadweight puts 3 and the decline of jointed shaft 4 realizations self, make sand sealing knife break away from the sand seal device that goes in ring, when belt sand seal device drops to when breaking away from sand sealing knife fully, the support bar 5 sand seal device that will go in ring supports, and no longer descends..Be sealed and matched labyrinth sealing row that chassis frame and the furnace wall on top constitute of the sand sealing groove of loop configuration becomes 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.
