Description

Technical Field

[0001] The utility model relates to the technical field of aluminum silicate felt fixing, in particular to a multi-layer fixing device for aluminum silicate felt. Background Art

[0002] Aluminum silicate felt is a new type of high-temperature thermal insulation material. Its main raw material is aluminum silicate fiber, which is made through advanced production technology and high-temperature treatment. Aluminum silicate felt is often used for building insulation and equipment insulation. It is also used as a lining material for heating furnaces in the metallurgical industry and as a lining material for reaction tanks in the chemical industry. It also plays an important role in high-temperature thermal insulation in the fields of aerospace, petrochemicals, electric power, etc., and in fire insulation of military equipment.

[0003] Aluminum silicate felt needs to be fixed when it is stacked in multiple layers. The common fixing method is gluing, which is not conducive to subsequent disassembly and is not flexible enough. Fixing by clamping with plywood depends on the spacing of the plywood, which is usually fixed and cannot be adjusted. It is difficult to apply to aluminum silicate felts of different thicknesses. The plywood spacing can be adjusted but it is inconvenient to lock the card, which can easily cause the aluminum silicate felt to loosen and lack stability. Therefore, we propose a multi-layer fixing device for aluminum silicate felt. Utility Model Content

[0004] The purpose of the present utility model is to provide a multi-layer fixing device for aluminum silicate felt to solve the problems raised in the above background technology.

[0005] The cam is fixedly mounted on the outside of the drive unit and has a first end fixed to the top of the drive unit, the second end of the first end of the first gear is fixedly mounted on the drive unit, and the second end of the first gear is fixedly mounted on the outside of the drive unit.

[0006] Preferably, one end of the driving plate extends into a sliding groove on the inner wall of the driving cavity.

[0007] Preferably, a first friction plate is adhered to the surface of the dynamic clamping plate, which improves the friction force of the surface of the dynamic clamping plate and makes the aluminum silicate felt clamped more firmly.

[0008] Preferably, a second friction plate is adhered to the surface of the fixed clamping plate, which improves the friction force of the surface of the fixed clamping plate and makes the aluminum silicate felt clamped more firmly.

[0009] Preferably, the outer wall of the knob is provided with locking grooves at equal intervals.

[0010] Preferably, one end of the bolt extends into the dovetail groove on the outer wall of the push plate and is fixed with a dovetail block. The bolt is rotated to drive the push plate to translate along the guide rod, and the push plate drives the locking rod to translate.

[0011] Preferably, a guide rod passes through the interior of the push plate, and both ends of the guide rod are fixedly connected to the inner wall of the cavity.

[0012] Preferably, one end of the locking rod extends into the locking hole at the bottom of the cavity, and the locking rod extends from the locking hole and is inserted into the locking groove on the outer wall of the knob to lock the rotating rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The aluminum silicate felt is placed between the fixed splint and the movable splint, and the aluminum silicate felt is the first layer of aluminum silicate felt. The second, third, fourth and fifth layers of aluminum silicate felt are placed between the movable splint above the fixed splint. The rotating knob drives the second bevel gear to rotate, and the second bevel gear drives the screw to rotate through the first bevel gear, so that the driving plate drives the movable splint to move downward. The movable splint clamps and fixes each layer of aluminum silicate felt. The spacing between the movable splints is adjustable and can be adjusted separately, so as to meet the fixing requirements of aluminum silicate felts of different thicknesses. The fixed splint is movable, which makes the aluminum silicate felt easy to disassemble and assemble.

[0015] The setting of the first friction plate and the second friction plate improves the friction force on the surface of the movable splint and the fixed splint, making the aluminum silicate felt clamped more firmly. The rotating bolt drives the push plate to translate along the guide rod, and the push plate drives the locking rod to translate. The locking rod extends from the lock hole and is stuck in the lock groove on the outer wall of the knob, locking the rotating rod and then locking the screw rod, so that the position of the movable splint is fixed and not easy to loosen, thereby improving the stability of the aluminum silicate felt.

The second, third, fourth, and fifth layers of aluminum silicate felt are placed between the movable splint 5 above the fixed splint 7. By rotating the knob 13, the rotating rod 12 drives the second bevel gear 11 to rotate, and the second bevel gear 11 drives the screw rod 3 to rotate through the first bevel gear 10, so that the driving plate 4 drives the movable splint 5 to move downward, and the movable splint 5 clamps and fixes each layer of aluminum silicate felt. The spacing between the movable splints 5 is adjustable and can be adjusted separately, thereby meeting the fixing requirements of aluminum silicate felts of different thicknesses.

[0026] The fixed clamping plate 7 is movable, making the aluminum silicate felt easy to disassemble and assemble;

[0027] A first bevel gear 10 is mounted on the outer wall of the screw rod 3, and a rotating rod 12 is mounted on the outer wall of the device body 1 on one side of the drive chamber 2.

The rotating bolt 15 drives the push plate 17 to translate along the guide rod 18, and the push plate 17 drives the locking rod 19 to translate. The locking rod 19 extends from the lock hole 20 and is stuck in the lock groove 23 on the outer wall of the knob 13, locking the rotating rod 12, and then locking the screw 3, so that the position of the movable splint 5 is fixed and not easy to loosen, thereby improving the stability of the aluminum silicate felt.
