Description
Technical field
The utility model relates to material heat treatment equipment technical fields, and in particular to a kind of displacement room for being heat-treated kiln.
Background technique
Displacement room is to ensure that roller kilns etc. are heat-treated the key equipment that process gas in kiln burner hearth reaches requirement concentration,
The both ends of burner hearth are set, gas displacement are completed in displacement room when material is into and out of burner hearth, to guarantee furnace gas concentration not
Become.Displacement room mainly includes the shell and more than two gate sealing devices with through channel, and gate sealing device is using liter
The structure type of actuator drive valve plate elevating movement is dropped, the inlet and outlet of through channel are opened when valve plate rises, when valve plate declines
The inlet and outlet of through channel are closed, and valve plate must can ensure that material passes through when rising, can guarantee again when falling effectively close
Envelope.
For the leakproofness for improving displacement room gate sealing device, the pressure that valve plate is compressed when valve plate is closed generally can be all set
Tight device.Pressing device can be accomplished in several ways, for example, by using multiple independent cylinders (generally more than ten) in difference
Position compresses flashboard, and for this structure there are at high cost, I& M difficulty is big, is difficult to control, reliability is poor
The shortcomings that, and the service life under environment dusty is difficult to ensure.For another example application No. is 201721564505.6 China specially
Benefit discloses a kind of displacement room for atmosphere roller kilns, is to be mounted on valve plate by gas by parallelogram linkage
On the crane of cylinder driving, when cylinder drive valve plate moves straight down, valve plate can generate lateral displacement simultaneously, to realize
Compress sealing.The displacement room is designed by cleverly structure, is not needed that compression driving device is separately configured, is using lifting cylinder
Substrate hold-down function is realized, has the advantages that structure is simple, occupies little space, is at low cost, being easy to operate and control.But this is set
It changes the gate sealing device of room to compress to be unilateral, when compressing, valve plate can generate and compaction direction opposite effect crane
Power, cause crane and lifting actuator will receive biggish biasing force and beat power, in actual use, crane and
Lifting actuator, which can be deformed, even to be damaged, to influence the leakproofness and service life of gate sealing device.Especially with
Roller kilns cross-sectional width it is more and more wider, the width for replacing room also becomes wider than before, and the width of valve plate is also required with area
Bigger, in that case, crane, which generates slight deformation and offset, all can cause pressing force inadequate, not so as to cause sealing
Tight even seal failure can be also deformed and shadow even if guiding mechanism is arranged in the two sides of crane at the middle part of crane
Ring sealing.In addition, the complicated integral structure of gate sealing device, at high cost, manufacture assembly hardly possible in the displacement room, and weight is big,
High to the performance requirement of cylinder, stability when work is poor.
