As shown in fig. 1 to 9, the present embodiment provides an assembled filter bag frame comprising a top ring 100 and a frame body, the top ring 100 having a central hole 11, the frame body comprising a support ring 20, ribs 30 and connectors 40.
The support ring 20 has a plurality of along horizontal interval distribution, the last edge circumference equipartition of support ring 20 has a plurality of first through-holes 21, first through-hole 21 is along longitudinal extension, first through-hole 21 is along vertically running through support ring 20, and preferred first through-hole 21's quantity is eight.
A plurality of ribs 30 are distributed along the circumferential direction of the support ring 20, and the ribs 30 extend along the longitudinal direction and penetrate through the first through holes 21 on the support ring 20. The number of ribs 30 is the same as the number of first through-holes 21 in support ring 20, so that the number of ribs 30 is correspondingly eight. The top ring 100 is detachably connected to the top of the plurality of ribs 30.
The connectors 40 are configured to connect the support ring 20 and the ribs 30 together, preferably the connectors 40 are configured to removably connect the support ring 20 and the ribs 30.
In this embodiment, the top ring 100 is detachably connected to the frame body, and each structure constituting the frame body is also detachably connected, so that the entire filter bag frame can be assembled at an installation site, and disassembled into a single component during transportation and storage, thereby facilitating storage and transportation and reducing the storage and transportation cost.
In one embodiment, a plurality of second through holes 22 are distributed in the circumferential direction of the support ring 20, that is, the number of the second through holes 22 is eight, the second through holes 22 are arranged in one-to-one correspondence with the first through holes 21, the second through holes 22 are communicated with the first through holes 21, and preferably, the center line of the second through holes 22 is perpendicular to the center line of the support ring 20. A plurality of third through holes 31 are formed in the ribs 30, the third through holes 31 are arranged in one-to-one correspondence with the support rings 20, and preferably, the diameters of the third through holes 31 are equal to the diameters of the second through holes 22.
The support ring 20 can be moved to a position where the second through holes 22 are communicated with the third through holes 31, that is, the ribs 30 are inserted into the first through holes 21 on the support ring 20, and the position of the support ring 20 on the ribs 30 is adjusted by moving the support ring 20 or the ribs 30, so that the second through holes 22 on the support ring 20 are communicated with the corresponding third through holes 31 on the ribs 30.
The connecting member 40 is in a thread shape or a rope shape, and the connecting member 40 may be made of a metal material or a nylon material, such as a steel wire rope, a nylon rope, or a binding wire. The connecting member 40 passes through the second through hole 22 and the third through hole 31 which are communicated with each other, and the connecting member 40 passes through at least two of the second through holes 22 (since the second through hole 22 is communicated with the third through hole 31 at this time, the connecting member 40 also passes through at least two of the third through holes 31). Since there are eight second through holes 22 in each support ring 20, four connectors 40 are required when the connectors 40 pass through only two of the second through holes 22, and there are various ways in which the connectors 40 pass through the second through holes 22. The two ends of the connecting member 40 can be directly connected together, or a knot or a plug that cannot pass through the second through hole 22 can be tied to ensure that the connecting member 40 does not break away from the second through hole 22.

This problem is avoided by connecting support ring 20 to ribs 30 by means of connectors 40.
In one embodiment, one end of the connecting member 40 sequentially passes through all the second through holes 22 of the supporting ring 20 in a clockwise or counterclockwise direction, and the other end of the connecting member 40 is connected to the one end of the connecting member 40, that is, the connecting member 40 and the supporting ring 20 are arranged in a one-to-one correspondence, and then the two ends of the connecting member 40 can be connected together by knotting. Preferably, the connecting member 40 is a binding wire, so that the two ends of the binding wire are tied together by screwing, and the binding wire can pass through the second through hole 22 and the third through hole 31 conveniently.
In one embodiment, the top ring 100 is detachably connected to the tops of the plurality of ribs 30 through a connection structure, which includes a connection portion 32, a sliding groove 12, a support 50, a positioning block 13, and a limiting member 60.
Connecting portion 32 sets up the top of rib 30, connecting portion 32 can through modes such as integrated connection, bonding, welding or joint with rib 30 fixed connection. The sliding grooves 12 are uniformly distributed along the circumferential direction of the top ring 100, and the sliding grooves 12 penetrate through the inner wall of the top ring 100. The sliding grooves 12 are arranged corresponding to the ribs 30, i.e. one rib 30 corresponds to one or more sliding grooves 12.
The supporting member 50 is slidably disposed in the sliding groove 12, and one end of the supporting member 50 may extend to the outer side of the outer circumferential surface of the top ring 100 and support the connecting portion 32. The one end of the support member 50 may support the support portion 62 by passing through the connection portion 32 or at the outer side of the connection portion 32, or the like. The other end of the supporting member 50 is held inside the inner circumferential surface of the top ring 100, so that the direction in which the supporting member 50 slides out of the sliding groove 12 is limited, that is, the supporting member 50 can slide out of the sliding groove 12 only when sliding into the top ring 100, and cannot slide out of the sliding groove 12 when sliding out of the top ring 100 because being blocked by the connecting portion 32, and then the supporting member 50 is limited from sliding into the inside of the top ring 100 by the limiting member 60, so that the supporting member 50 keeps supporting the connecting portion 32.
The positioning blocks 13 are distributed on the outer peripheral surface of the top ring 100 in a plurality, the positioning blocks 13 are arranged corresponding to the ribs 30, preferably, the positioning blocks 13 are arranged corresponding to the ribs 30 one by one, that is, the number of the positioning blocks 13 is eight. The positioning block 13 is used to block the upward movement of the connecting portion 32 when the connecting portion 32 is supported by the support member 50, and particularly, the connecting portion 32 may vibrate upward and may be separated from the support member 50 when the filter bag frame is in operation, while the positioning block 13 blocks the upward movement of the connecting portion 32, thereby ensuring that the connecting portion 32 is reliably supported by the support member 50 during the operation cycle of the filter bag frame.
Further, when the connecting portions 32 of the plurality of beads 30 are supported by the corresponding support members 50, the inner sides of the connecting portions 32 contact or abut against the outer peripheral surface of the top ring 100. The above structure prevents the connecting portion 32 from moving laterally during the operation of the filter bag frame, prevents the connecting portion 32 from being separated from the support of the support member 50 by moving laterally, and further ensures that the connecting portion 32 is reliably supported by the support member 50. Preferably, a portion of the outer circumferential surface of the top ring 100 is formed with eight flat surfaces forming a regular octagon, and the inner side of each connecting portion 32 is attached to a corresponding flat surface, so that the connecting portion 32 is moved to a position below the corresponding positioning block 13 and supported by the supporting member 50.
In one embodiment, the connecting portion 32 has a T-shaped or Y-shaped cross section, each rib 30 corresponds to two sliding slots 12, and the supporting member 50 includes a supporting block 51 and a connecting block 52. The supporting blocks 51 are arranged in one-to-one correspondence with the sliding grooves 12, the connecting blocks 52 are located in the central hole 11, the two supporting blocks 51 are connected together by the connecting blocks 52, and the connecting blocks 52 are integrally connected with the supporting blocks 51. Since there are two support blocks 51, the connecting portion 32 is suspended between the two support blocks 51.
The stopper 60 includes a stopper portion 61 and a support portion 62, the stopper portion 61 is configured in a cylindrical shape, and the connection block 52 is provided between an outer circumferential surface of the stopper portion 61 and an inner circumferential surface of the top ring 100, that is, the connection block 52 is located between the outer circumferential surface of the stopper portion 61 and the inner circumferential surface of the top ring 100. The support portion 62 is located above the stopper portion 61 and integrally connected to the stopper portion 61, and the support portion 62 is supported by the top ring 100. Preferably, the central hole 11 is a stepped hole, the support portion 62 is placed on a stepped surface, the upper surface of the support portion 62 is coplanar with the upper surface of the top ring 100, and the outer diameter of the support portion 62 is the same as or similar to the diameter of a part of the stepped hole for accommodating the support portion 62, so that the limiting member 60 is assembled with the top ring 100, and has a compact structure and an attractive appearance.
During assembly, all the supporting members 50 support the corresponding connecting portions 32, the inner sides of all the supporting members 50 move to positions where the supporting members 50 are not blocked from being inserted, and then the limiting members 60 are directly inserted into the central holes 11 of the top ring 100, so that the limiting members 60 limit all the supporting members 50, and the structure is simple and the operation is convenient.
In one embodiment, the connecting structure further includes a receiving groove 521 and a compression spring 53. The accommodating groove 521 is disposed on an outer side surface of the connecting block 52, and both ends of the compression spring 53 are respectively abutted or contacted with an inner circumferential surface of the top ring 100 and a groove bottom of the accommodating groove 521. When the compression spring 53 is in a natural state, one end of the compression spring 53 may be spaced from the inner circumferential surface of the top ring 100 or the inner circumferential surface of the top ring 100 by a predetermined distance, and in either case, the outer surface of the support block 51 is located in the slide groove 12, and the outer surface of the support block 51 is spaced from the outer circumferential surface of the top ring 100 by a predetermined distance.
The reason for the above setting is: since the connecting portion 32 has a T-shaped or Y-shaped cross section, if one end of the supporting block 51 protrudes to the outside of the outer circumferential surface of the top ring 100 during the process of moving the connecting portion 32 to a position where the connecting portion is supported by the supporting block 51 and the upward movement is restricted by the positioning block 13, the movement of the connecting portion 32 is blocked, and at this time, only the supporting block 51 is pressed into the slide groove 12, or during the insertion of the supporting block 51 into the slide groove 12, it is ensured that one end of the supporting block 51 does not protrude to the outside of the outer circumferential surface of the top ring 100, which may cause inconvenience in the assembling operation. With the above arrangement, when the supporting block 51 is inserted into the chute 12, one end of the supporting block 51 does not protrude to the outside of the outer peripheral surface of the top ring 100 due to the blocking of the pressing spring 53, thereby facilitating the assembly.
In one embodiment, the lower end of the position-limiting portion 61 is tapered or the outer edge of the bottom of the position-limiting portion 61 is provided with a chamfer, and when the lower end of the position-limiting portion 61 is tapered, the tapered structure is that the outer diameter of the upper end is large and the outer diameter of the lower end is small. With the above arrangement, the stopper portion 61 can be inserted into the center hole 11 of the top ring 100 more smoothly.
In one embodiment, a positioning protrusion 33 is disposed on the top of the connecting portion 32, preferably, the positioning protrusion 33 is in a shape of a hemisphere or a frustum, and a positioning groove adapted to the positioning protrusion 33 is disposed on the bottom of the positioning block 13. By the arrangement of the positioning projections 33 and the positioning grooves, it is facilitated to move the connection portions 32 to the correct positions supported by the supporting blocks 51 more quickly.
In one embodiment, part or all of the supporting block 51 is made of a hard magnetic material, that is, the supporting block 51 itself is a magnet or the supporting block 51 is embedded with a magnet, and the top ring 100 is made of a soft magnetic material. Because the length of the rib 30 is long, if the rib 30 needs to be erected for assembly, a platform with a certain height is required to be erected, and therefore the rib 30 is suitable for being horizontally placed and then assembled with the top ring 100, the structure of the supporting member 50 in the previous embodiments is inconvenient to assemble, namely, after the supporting member 50 is inserted into the sliding groove 12, part of the supporting member 50 can fall off from the sliding groove 12 under the action of self gravity, and through the arrangement of the embodiment, the supporting member 50 can be kept in the sliding groove 12 through proper magnetic force, so that the assembly is convenient.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
