Detailed Description
The detailed features and advantages of the present invention are described in detail in the following detailed description, which is sufficient for any person skilled in the art to understand the technical contents of the present invention and to implement the present invention, and the related objects and advantages of the present invention can be easily understood by any person skilled in the art from the disclosure, claims and drawings of the present specification. The following examples are intended to illustrate the invention in further detail, but are not intended to limit the scope of the invention in any way.
Referring to fig. 1 to 6, the present invention provides a bag filter convenient for replacing a filter bag, comprising:
a ring frame 1, comprising: the filter bag comprises a vertical fastening piece 2 and a transverse connecting piece 3 vertically arranged on one side of the vertical fastening piece 2, wherein the cross section of the transverse connecting piece 3 is L-shaped after being connected with the vertical fastening piece 2 into a whole, the transverse connecting piece 3 is provided with at least eight first threaded holes 4, one side of the transverse connecting piece 3 facing the vertical fastening piece 2 is provided with at least eight counter bores 5, springs (not shown in the figure) are arranged in the counter bores 5, the length of the springs is longer than the depth of the counter bores 5 when the springs are in an extension state, the length of the springs is not more than the depth of the counter bores 5 when the springs are in a compression state, after the filter bag 9 is installed, the springs are in a compression state, the tightness among the filter bag 9, the transverse connecting piece 3 and the annular pressing block 7 cannot be influenced, after the filter bag 9 is blocked due to long-time filtration, the annular pressing block 7 can be pushed out from one side of the filter bag 9 by the 6 under the condition that the bolts are taken down, thereby facilitating the removal of the filter bag 9 from the L-shaped annular frame 1 and the replacement of the filter bag;
the annular pressing block 7 is arranged in the annular frame 1, and a second threaded hole 8 matched with the first threaded hole 4 is formed in the annular pressing block;
the edge of the filter bag 9 is arranged between the transverse connecting sheet 3 and the annular pressing block 7, and the transverse connecting sheet 3 is connected with the filter bag 9 and the annular pressing block 7 through bolts or screws.
In particular, for convenience of processing, the counter bore 5 and the first threaded hole 4 are coaxially arranged, a step surface 10 is formed in front of the counter bore 5 and the first threaded hole 4, and the diameter of the counter bore 5 is larger than the inner diameter of the first threaded hole 4, so that one end of the spring can be located on the step surface 10, the other end of the spring can be in contact with the annular pressing block 7, and meanwhile, a bolt or a screw is located in the spring, so that a limiting and supporting effect can be achieved on the spring, the spring is prevented from being deformed when the annular pressing block 7 is locked, the original position of the spring is influenced, and the annular pressing block 7 is not pushed out conveniently.
Particularly, the step surface 10 is provided with an accommodating groove 11 matched with the spring, and the accommodating groove 11 can play a role in limiting and fixing the end part of the spring to prevent the spring from falling out of the counter sink 5 to influence subsequent installation, disassembly and replacement.
In particular, the inner diameter of the spring is larger than that of the first threaded hole 4, so that the spring is not rubbed by the bolt or the screw when the bolt or the screw is screwed down, and the bolt or the screw can be smoothly and threadedly connected with the first threaded hole 4 and the second threaded hole 8 conveniently.
Particularly, one side of the transverse connecting sheet 3 facing the vertical fastening sheet 2 is provided with an annular groove 12, and the section of the annular groove 12 is arc-shaped; an annular bulge 13 extends outwards from one side surface of the annular pressing block 7, the end part of the annular bulge 13 is in a circular arc shape matched with the annular groove 12, and the annular bulge 13 is made of a silica gel material; therefore, after the annular frame 1, the filter bag 9 and the annular pressing block 7 are fastened through bolts or screws, the annular protrusions 13 are made of silica gel and can enter the annular groove 12, the sealing performance among the three is further improved, when the filter bag 9 needs to be replaced, after the bolts or screws are taken down, the annular protrusions 13 are restored to the original positions, the annular pressing block 7 and the filter bag 9 are forced to be separated from the annular frame 1, and therefore the replacement of the filter bag 9 can be completed quickly.
Particularly, when the filter bag 9 is installed, the edge of the filter bag cannot be fixed, so that the exposed part of the outer part of the filter bag may have different sizes, and meanwhile, the filter bag 9 may be separated from the annular frame 1 and the annular pressing block 7 due to the small fixed part, so that the edge of the filter bag 9 is provided with a fixed ring 14, and a groove 15 corresponding to the fixed ring 14 extends inwards from the joint position of the transverse connecting sheet 3 and the vertical fastening sheet 2; so when installation or change filter bag 9, only need be located recess 15 with position circle 14, can accomplish the spacing at filter bag edge fast, simultaneously because recess 15 is located ring frame 1 handing-over position, consequently can not exert an influence to the leakproofness between filter bag and transverse connection piece 3 and the annular briquetting 7.
Specially, the filter bag 9 edge is equipped with one and the flange layer 6 of the width such as transverse connection piece 3, in the utility model discloses in, the width of flange layer 6 is 30cm, and the hardness at this flange layer multiplicable filter bag 9 edge to play a supporting role to filter bag 9 edge, can not appear the too much or too little problem of filter bag 9 fixed part when installation or change filter bag 9.
In the present invention, the fixing element 14 and the flanging layer 6 can be designed simultaneously or only one. When the bag filter is assembled, after the filter bag 9 is pulled out along the transverse connecting sheet 3, the flanging layer 6 can be overlapped with the transverse connecting sheet 3, and the spring is in an uncompressed state; then inserting the annular pressing block 7 into the inner wall of the vertical fixing piece 2 to enable the annular pressing block 7 to be in contact with the edge of the filter bag 9; and then, fixing the annular pressing block 7, the flanging layer 6 and the transverse connecting sheet 3 by adopting bolts or screws, wherein the spring is gradually in a compressed state, and the annular bulge 13 falls into the annular groove 12 and is in an extended state, so that the assembly of the bag filter can be completed. When the filter bag 9 is blocked, the bolt or the screw is rotated reversely, the spring is gradually stretched until the annular bulge 13 is recovered to the original position, the annular bulge 13 is released from the annular groove 12 and recovered to the original position, the annular pressing block 7 can be pushed away from the filter bag 9 and the frame 1 under the action of the spring and the annular bulge 13, then the blocked filter bag is taken down, and the replacement of the filter bag can be conveniently and quickly completed by installing a new filter bag according to the method.
