Abstract
The present invention relates to a metal mesh bag filter for a fluidized bed process apparatus, more particularly, to a bag filter for use in a fluidized bed process apparatus, which is formed of a mesh metal mesh to prevent foreign matter from mixing into raw materials during operation, The present invention relates to a metal mesh bag filter for a fluidized bed process machine, which can reduce costs and is easy to be joined and separated, thereby improving usability.
In order to achieve the above-mentioned object, the present invention provides a filter device comprising: a filter portion formed of a metal mesh; a coupling portion coupled to an upper end of the filter portion and having a thread formed on an outer peripheral surface thereof, And a filter bracket having a filter coupling hole formed with a corresponding thread on an inner circumferential surface so that the coupling portion is screwed from below and a packing portion for sealing a space between the outer circumferential surface and the bag filter chamber.
Description
The present invention relates to a metal mesh bag filter for a fluidized bed process apparatus, more particularly, to a bag filter for use in a fluidized bed process apparatus, which is formed of a mesh metal mesh to prevent foreign matter from mixing into raw materials during operation, The present invention relates to a metal mesh bag filter for a fluidized bed process machine, which can reduce costs and is easy to be joined and separated, thereby improving usability.
The fluidized bed process is a process in which a powder formed in the form of granules or fine granules as known in the art is dried and commercialized by sending hot air at a proper flow rate from the bottom of the perforated plate to form a fluidized bed In particular, water-containing powders are corroded by water during the distribution process, and thus chemical or pharmaceutical companies often use the chemicals to dry them.
A conventional technology disclosed as a fluidized bed process unit is Korean Patent No. 10-1138494 (registered on April 13, 2012, hereinafter referred to as "Prior Art 1"). Air is introduced through the
At this time, when the hot air is continuously supplied to the
In the above-described conventional art, the bag filter installed in the bag filter chamber is shaken by the reciprocating operation of the shaking cylinder depending on the degree of clogging for a predetermined period of time, and the dust adhering to the outside of the bag filter is shaken off. This is because if the raw material is continuously accumulated in the bag filter by the operation of the fluidized bed process unit, air is not properly discharged through the bag filter, and if the bag filter is clogged by the raw material during the operation, It is to shake.
However, since the conventional bag filter is formed of fibers, there is a problem that the foreign matter of fibers is mixed with the raw material when the filter bag is shaken up and down, thereby increasing the probability of failure of the finished product.
Furthermore, since the conventional bag filter is fitted into the fitting hole formed in the filter bracket and is fitted from above, the upper part of the bag filter is engaged with the filter bracket so that the bag filter is disengaged from the filter bracket when wiggled.
In order to solve the above problems, the present invention has been made to solve the above problems, and it is an object of the present invention to provide a bag filter which is formed of a metal mesh net so as to prevent foreign matter from being generated even when the bag filter is shaken, The metal mesh bag filter for a fluidized bed process apparatus, which is fixed through a screw connection and does not separate from the filter bracket when it is shaken, is provided.
In order to accomplish the above object, the present invention provides a filter device comprising: a filter portion formed of a metal mesh; a filter member coupled to an upper end of the filter portion and having a thread formed on an outer circumferential surface thereof, And a filter bracket having a filter coupling hole having a corresponding thread on an inner circumferential surface of the coupling portion to be screwed from below and a packing portion for sealing a space between the outer circumferential surface and the bag filter chamber.
In this case, the coupling portion is formed with a step at a lower portion of the thread to prevent the filter bracket from protruding upward when the filter bracket is threaded with the filter bracket.
Further, the filter bracket has a shape corresponding to the inner shape of the bag filter chamber, and a plurality of filter engagement holes into which the engagement portions are screwed are formed at regular intervals, and the packing portion is formed along the rim of the filter bracket A plurality of vertical plates extending downward from the filter bracket at predetermined intervals, and a plurality of fixing screws and fixing nuts for fixing the vertical plates to the packing.
In the present invention as described above, when the heated air is supplied to dry the raw material in the fluidized bed process unit, the raw material adheres to the outside of the filter net when circulating the introduced air, and in the process of removing the foreign material, It is possible to prevent the filter net from being detached from the filter bracket when the filter net is shaken by firmly coupling the filter net and the filter bracket through the screw connection, There is a further advantage that a packed part can be easily replaced with a worn packing during use.
