Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sealing material, specifically relates to a sealing strip with protective sleeve and the inlet and outlet structure of containing sealing strip. BACKGROUND

[0002] The feeder bin of metallurgical industry is used for closing and opening the control equipment of raw material access channel, and the sealing strip is used for sealing at the inlet and outlet of the bin and the feeder equipment, which can effectively prevent the fine metal raw material after screening from leaking out of the gap.

[0003] The sealing strip currently used adopts the fixing mode that the sealing strip is bonded by a large amount of glue in the groove at the edge of the inlet and outlet of the equipment, which has the problem of environmental protection; meanwhile, due to the conditions such as unfirm bonding of the glue in transportation, hoisting and on-site construction, the exposed sealing strip is extremely easy to be contacted and damaged by hoisting steel wire rope, metal objects, ore and other hard objects. In addition to the factors such as dust in the on-site environment and limited space position, the bonding operation of the glue is difficult when the sealing strip is replaced, and the operation specification of the workshop assembly cannot be reached. Since the sealing strip is not an integral frame, it also needs to be connected in multiple sections. If the operation is improper, a gap will appear at the connection position. Not only is it easy to leak dust, but also it is not beautiful. The sealing strip is also an elastic body, which is exposed outside during use, and is directly contacted with dust and other objects on site. After a long time of use, the sealing strip is easy to lose elasticity and lose the dust removal and buffering effect, and cannot reach the ideal service life. The sealing strip material also has the characteristics of not being resistant to high temperature, and the application range is restricted by the temperature of various materials. CONTENT OF THE UTILITY MODEL

[0004] In view of the problems such as easy damage of the sealing strip in the prior art, the utility model provides a sealing strip with protective sleeve and the inlet and outlet structure containing the sealing strip to solve the above problems.

[0005] In the first aspect, the utility model provides a sealing strip with protective sleeve, which comprises a sealing strip; the protective sleeve is an annular object, and a ring of sealing pieces is arranged on the outer side; the sealing piece is a zipper or a self-sealing strip; the inside of the protective sleeve is filled with the sealing strip.

[0006] The material of the protective sleeve used in the utility model is silica gel cloth, which is resistant to high and low temperature, anti-aging, soft and high in strength, and corrosion-resistant.

[0007] Further, the material of the sealing strip is polyurethane, vulcanized rubber or silica gel.

[0008] In a second aspect, the utility model provides a kind of inlet and outlet structure comprising the sealing strip, protective sleeve is installed in the installation groove of bin door frame.

[0009] Further, the protective sleeve is fixed in the installation groove by magic tape. Magic tape is a kind of connector that is easy to use, durable, reusable and flexible adjustment, which is divided into fine and soft fiber surface and relatively hard hooking bristle surface. One side is fixed in the installation groove, and the other side is installed on the outside.

[0010] Further, the magic tape is fixed on three sides of the installation groove. This ensures the firmness and reliability of the protective sleeve in the installation groove.

[0011] The working principle of the utility model is as follows: when the sealing strip of the inlet and outlet structure is replaced, the sealing element (zipper or self-sealing strip) is opened, and the sealing strip is taken out. Since the protective sleeve is connected with the installation groove by magic tape, the protective sleeve is not easy to fall off or misalign. After the sealing strip is completely taken out, the newly replaced sealing strip is inserted into the protective sleeve in sections. Each insertion closes a section of the sealing element, which can effectively prevent the already installed sealing strip from falling off. After the installation is completed, the protective sleeve is also closed, and the device inlet and outlet structure can be used after being closed.

[0012] The utility model has the advantages that:

[0013] The sealing strip with protective sleeve provided by the utility model modifies the original installation method of directly bonding the sealing strip in the installation groove to an installation method of additionally installing a protective sleeve outside the sealing strip. Firstly, the risk of damage caused by contact with steel wire rope, metal objects, ore and other hard objects is avoided. Secondly, the sealing strip with protective sleeve provided by the utility model is easy to maintain. Due to the influence of factors such as high dust in the production site environment and limited space position, the original spare part replacement is difficult to operate with glue bonding. Since the sealing strip is not a whole frame, it needs to be connected in multiple sections. If not properly connected, gaps will appear at the connection position, which is easy to leak dust. The sealing strip with protective sleeve provided by the utility model can be installed by opening the sealing element, putting the sealing strip into it and closing the sealing element. This not only prevents dust leakage, but also makes it more convenient to replace the sealing strip. DRAWINGS

Obviously, other drawings can also be obtained by those skilled in the art without creative labor.
