Detailed Description

The invention will be further elucidated with reference to the drawings and the embodiments, which are exemplary only and do not limit the scope of the invention.

As shown in fig. 1-4, a flue gas filtering chamber structure with a filter capable of being conveniently assembled and disassembled comprises a base 1 provided with a containing cavity 11 and a filter 2 arranged in the containing cavity 11, wherein the filter 2 comprises a connector 21 and a filter screen 22, the outer wall of the connector 21 is sealed with the inner wall of the base 1 and is provided with an inner cavity 211, the filter screen 22 is arranged on the connector 21, and an air inlet 12 and an air outlet 13 which are respectively communicated with the containing cavity 11 and the inner cavity 211 are arranged on the base 1; the filter 2 is inserted in the housing chamber 11; a surface cover 23 is arranged at the outer end of the connector 21 and positioned outside the end surface of the base 1, preferably, the surface cover 23 and the connector 21 are integrally formed; the two sides of the end of the base 1 close to the surface cover 23 are symmetrically provided with a convex part 14 with a blocking position respectively; the two projections 14 are detachably fitted with an eccentric shaft 3 which can be pressed against the face cover 23 by means of detents. Specifically, the diameter of the face cover 23 is larger than the width of the accommodating cavity 11; two projections 14 are provided on the end face of the base 1 and a face cover 23 is located between the two projections 14. The filter 2 is inserted into the accommodating cavity 11, the face cover 23 is used for positioning, and finally the eccentric shaft 3 is used for tightly propping against the face cover 23, so that the filter 2 can be stably fixed on the base 1; when the filter 2 needs to be detached, the filter 2 can be pulled out only by taking out the eccentric shaft 3, the operation process is simple and convenient, and the screw thread is not needed to be worried about corrosion because the screw thread connection is not adopted.

As shown in fig. 1 and 3, a first seal ring 5 is arranged between the surface cover 23 and the end surface of the base 1; the eccentric shaft 3 comprises a rotating rod 31 arranged between the two convex parts 14, and one side surface of the rotating rod 31 is a first arc surface 311, a plane 312 and a second arc surface 313 which are sequentially connected from top to bottom; an eccentric rod 32 deviating from the axle center of the rotating rod 31 is respectively arranged on the two end surfaces of the rotating rod 31, and the eccentric rod 32 is close to the side surface of the rotating rod 31 far away from the plane 311; the two eccentric rods 32 are respectively and rotatably arranged in the two clamping positions; when the eccentric shaft 3 abuts against the face cover 23, the flat surface 311 abuts against the surface of the face cover 23. The first arc-shaped surface 311 and the second arc-shaped surface 313 can make the rotating rod 31 rotate more smoothly; preferably, the two positions are a card hole 141 and a card slot 142, respectively, and certainly, both the two positions may be card slots, in this embodiment, the two positions are a card hole 141 and a card slot 142, respectively; as shown in fig. 3, the eccentric rod 32 above the rotating rod 31 is a long rod, the eccentric rod 32 below the rotating rod 31 is a short rod, the length of the long rod is longer than that of the short rod, and the distance from the end surface of the rotating rod 31 provided with the long rod to the notch of the clamping groove 142 facing the rotating rod 31 is not less than that of the short rod, so as to prevent the short rod from leaving the clamping hole 141; the catching hole 141 can play a role of fixing the rotating rod 31. When the filter 2 needs to be fixed, the rotating rod 31 is rotated along the radial direction, so that the first sealing ring 5 is compressed by the surface cover 23 towards the filter screen 22 (the first sealing ring 5 is made of an elastic material and has elasticity), and the effect of fixing the filter 2 can be realized until the plane 311 is attached to the surface cover 23, wherein when the plane 311 is attached to the surface cover 23, a certain gap is still left between the surface cover 23 and the end surface of the base 1 to prevent the rotating rod 31 from being incapable of rotating, and gas is difficult to leak due to the existence of the first sealing ring 5; when the filter 2 needs to be disassembled, the rotating rod 31 is rotated along the radial direction, the face cover 23 continues to compress the first sealing ring 5 until the plane 311 leaves the face cover 23, then the rotating rod 31 is moved along the axial direction to enable the eccentric rod 32 to leave the clamping hole 141, and then the eccentric shaft 3 is taken away to draw out the filter 2.

The rotary rod 31 is also provided with an insertion hole 314 for inserting the grip 4. Specifically, the insertion hole 314 is provided on the side of the rotating rod 31 away from the plane 311. The handle 4 can help people to easily pull the rotating rod 31 and the handle 4 can be determined whether to be installed on the rotating rod 31 according to the requirement.

A positioning portion 15 for positioning the connection head 21 is provided in the accommodation chamber 11 of the base 1. The positioning portion 15 is provided to better position the connection head 21.

A second seal ring 6 for sealing is provided on the contact surface between the connection head 21 and the positioning portion 15.

The present invention is not limited to the above embodiment, and if various modifications or variations of the present invention do not depart from the spirit and scope of the present invention, they are intended to be covered if they fall within the scope of the claims and the equivalent technology of the present invention.
