Description

Technical Field

[0001] The utility model relates to the technical field of ceramic fiber cotton production, in particular to a sealing device for a ceramic fiber cotton mixer. Background Art

[0002] Ceramic fiber loose wool is made by melting high-purity clay clinker, alumina powder, silica powder, chrome sand and other raw materials at high temperature in an industrial electric furnace to form a fluid. Then it is blown into fibers by compressed air or spun by a spinning machine, and then collected by a cotton collector to form ceramic fiber wool. The fiber cotton can be further processed into fiber blankets, boards, paper, cloth, ropes and other products.

[0003] When producing ceramic fiber cotton, multiple raw materials need to be mixed to facilitate subsequent production. Most mixers have inspection ports on the mixing barrel when in use, which can achieve a sealing effect during mixing to prevent raw materials from leaking. When maintenance is required, the mixer must be inspected through the sealing device.

[0004] Most of the existing sealing devices directly use a blocking plate and a sealing gasket for sealing when in use. Although the sealing gasket has a sealing effect, the deformation effect of the sealing gasket is poor. When the surface of the sealing gasket is contaminated with foreign matter, the sealing effect will be destroyed. The raw materials of ceramic fiber cotton are powder and granular, which are easily stuck on the surface of the sealing gasket, resulting in poor sealing effect of the sealing device and the raw materials are easy to escape from the gap. Utility Model Content

[0007] A hinge bolted to one side of the mounting seat, a top cover bolted to one side of the hinge, a first airbag installed inside the top cover, a mounting plate fixedly connected to one side of the top cover, a second airbag fixedly connected to the bottom of the mounting plate;

[0008] A connecting tube is connected to the top of the second airbag, and the other end of the connecting tube is connected to the first airbag. An extrusion frame is fixedly connected to one side of the mounting seat, an exhaust mechanism is installed inside the top cover, and lock buckles are installed at two locations on one side of the mounting seat.

[0009] Preferably, the exhaust mechanism includes a mounting shell fixed to the top of the inner cavity of the top cover and a compression spring arranged in the inner cavity thereof, and also includes a push rod fixed to both ends of the compression spring and an extrusion plate fixed to the other end thereof.

[0010] Preferably, a guide block is fixedly connected to the top of the extrusion plate, a guide groove is provided at the top of the inner cavity of the top cover, and an inner wall of the guide groove is slidably connected to the surface of the guide block.

[0011] Preferably, the cross-sectional shapes of the guide groove and the guide block are both T-shaped, and the guide groove and the guide block are used in conjunction with each other.

[0012] Preferably, the surface of the first airbag is movably connected to the inner wall of the positioning groove, and the first airbag is used in conjunction with the positioning groove.

[0013] Preferably, the extrusion frame is used in conjunction with the second airbag, and the extrusion frame is designed in a Z shape.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] The utility model can effectively block the gap between the mounting seat and the top cover through the cooperation of the first airbag and the second airbag, and has a good deformation effect.

The extrusion frame 9 is designed in a Z shape, and under this action, one side of it can be away from the top cover 4, and under this action, the extrusion frame 9 is prevented from being too close to the top cover 4 and affecting its normal rotation. An exhaust mechanism 11 is installed inside the top cover 4. The exhaust mechanism 11 is used in conjunction with the first airbag 5. Under this function, when the top cover 4 is opened, the air inside the first airbag 5 can be discharged into the second airbag 7 through the connecting pipe 8 under the action of the exhaust mechanism 11, so as to facilitate the opening of the top cover 4. Lock buckles 10 are installed at two places on one side of the mounting seat 1. The lock buckle 10 is used in conjunction with the top cover 4. Under this function, after the top cover 4 is fitted with the mounting seat 1, the mounting seat 1 and the top cover 4 can be fixed, so that the mounting seat 1 and the top cover 4 will not be easily separated, and the first airbag 5 is prevented from pushing the top cover 4 open under the action of air, thereby affecting the sealing of the device.

[0023] The exhaust mechanism 11 includes a mounting shell 111, one side of which is fixedly connected to the inner wall of the top cover 4, a compression spring 112 is provided in the inner cavity of the mounting shell 111, and both ends of the compression spring 112 are fixedly connected to push rods 113, and the surface of the push rod 113 is slidably connected to the inner wall of the mounting shell 111, under this action, the push rod 113 can slide inside the mounting shell 111, so that the push rod 113 is more stable when moving, and one end of the push rod 113 is fixedly connected to an extrusion plate 114, and the surface of the extrusion plate 114 is movably connected to the first airbag 5.

The cross-sectional shapes of the guide groove 12 and the guide block 13 are both T-shaped. The guide groove 12 and the guide block 13 are used in combination. Under this action, the guide block 13 can be effectively limited so that it will not easily break away from the inside of the guide groove 12, thereby avoiding the guide block 13 breaking away from the inside of the guide groove 12 and affecting the stability of the extrusion plate 114 when moving.

[0024] Working principle: First, the device is installed at the opening of the mixer through the mounting base 1. When the interior of the mixer needs to be inspected, the staff releases the limit of the lock 10 on the top cover 4, and then rotates the top cover 4 so that the extrusion frame 9 and the second air bag 7 are no longer in contact. Then, under the action of the compression spring 112, the extrusion plate 114 can push the air inside the first air bag 5 into the second air bag 7 through the connecting pipe 8 through the push rod 113. Then, the mixer can be inspected after the top cover 4 is rotated to one hundred and eighty degrees. After the inspection is completed, the top cover 4 is rotated to its original position, and then the second air bag 7 is squeezed under the action of the extrusion frame 9 so that the air inside it can enter the interior of the first air bag 5. With the cooperation of the positioning groove 2, the gap between the mounting base 1 and the top cover 4 is blocked to achieve a sealing effect, and then the lock 10 is used to fix the top cover 4.
