In order to achieve the above purpose, the basic scheme provided by the utility model is as follows: the kiln comprises a plurality of compaction units used for propping against the trapezoid sealing ring, wherein the plurality of compaction units are uniformly distributed on the periphery of the trapezoid sealing ring, and each compaction unit is connected with the top of the kiln body. The principle and the beneficial effects of the utility model are as follows: during installation, a plurality of compressing units are uniformly arranged on the periphery of the trapezoid sealing ring and are connected to the top of the kiln body, and then each compressing unit is connected with the trapezoid sealing ring. Compared with the prior art, the utility model compensates the gap between the trapezoid sealing ring and the cover plate due to abrasion in an extrusion mode, reduces the problem that the trapezoid sealing ring needs to be replaced frequently due to abrasion, prolongs the service life of the trapezoid sealing ring and reduces the production cost.
Scheme two, this preference of basic scheme, compress tightly the unit and be equipped with four, every compress tightly the unit all include the pressure strip and be used for with the pressure strip support tightly two compression components at trapezoidal sealing washer week sides, the even cloth of pressure strip is in the week side of sealing washer, extrudees through compression component for trapezoidal sealing washer is when being extruded, and the atress is more even, compensation trapezoidal sealing washer that can be better and apron between because wearing and tearing the clearance that produces.
Scheme three, this is the preference of scheme two, every hold-down assembly all includes L shape backup pad and is used for supporting the screw rod of compressing tightly the board, every one side and kiln body top of L shape backup pad are dismantled and are connected, every the opposite side of L shape backup pad is opened there is the through-hole, the nut has all been welded to the through-hole both sides, every the screw rod all passes through-hole and nut threaded connection, every all be equipped with two sleeve pipes on the pressure strip, every the sleeve pipe all moves about and cup joints the screw rod, and L shape backup pad has played fixed effect to the screw rod, and the screw rod activity cup joints in the sleeve pipe, has avoided the screw rod to take place the skew and lead to the pressure strip atress uneven at rotatory in-process, also can connect L shape backup pad and pressure strip, through adjusting screw, can make the pressure strip extrude trapezoidal sealing washer constantly.
In a fourth aspect, the method is preferable in the third aspect, and each L-shaped support plate is connected to the top of the kiln body through bolts.
The fifth scheme is the third scheme, each screw is fixedly connected with a rotary hand wheel, and workers can rotate the screw by using the rotary hand wheels, so that labor can be saved.

Description of the embodiments
The utility model is described in further detail below by way of specific embodiments:
reference numerals in the drawings of the specification include: the device comprises a compacting plate 1, an L-shaped supporting plate 2, a screw 3, a sleeve 4 and a rotary hand wheel 5.
Examples
As shown in fig. 1 to 3: the utility model provides an extension trapezoidal sealing washer life's device, including four compressing units that are used for supporting tight trapezoidal sealing washer, every compressing unit all includes pressure strip 1 and two compression subassembly, every compression subassembly all includes L shape backup pad 2 and is used for supporting tight screw rod 3 of pressure strip 1, the equal bolted connection in kiln body top in one side of every backup pad 2, open the opposite side of every backup pad 2 has the through-hole, the nut has all been welded to the through-hole both sides, every screw rod 3 all passes through-hole and nut threaded connection, all the rigid coupling has two sleeve pipes 4 on every pressure strip 1, every screw rod 3 all activity cup joints in sleeve pipe 4, all the rigid coupling has rotatory hand wheel 5 on every screw rod 3.
