Description

Technical Field

[0001] The utility model relates to the technical field of bag filters, in particular to an efficient bag filter. Background Art

[0002] A bag filter is a dry dust filtering device. It is suitable for collecting fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt. The fibrous fabric is used to filter the dust-containing gas. When the dust-containing gas enters the bag filter, dust particles with large size and specific gravity settle down due to the action of gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, and the gas is purified.

[0003] In the prior art, when replacing the filter bag, the cage needs to be removed first, and then the filter bag is taken out from the hole where the filter bag is installed. Then, a new filter bag is put into the hole of the dust collector for installing the filter bag, and the top of the filter bag is stuck at the hole. Finally, the cage is placed inside the filter bag, and the top side of the cage is stuck to the top of the filter bag, thus completing the replacement of the filter bag. When the filter bag is placed in the hole of the bag filter, at this time, the filter bag has no support, so it is necessary to manually align the filter bag along the axis to reduce the cross-sectional area, and then insert it into the hole. After that, the top of the filter bag is stuck at the hole, and the filter bag is restored to its original shape by inserting the cage. At this time, when bending the filter bag and inserting it into the hole and sticking the top of the filter bag at the hole, it is easy for the filter bag to be resisted, and then it is necessary to change the shape of the filter bag again, resulting in more time-consuming replacement of the filter bag, affecting the efficiency of filter bag replacement, thus easily affecting the working progress of the bag filter and further affecting the dust removal efficiency. Content of the Utility Model

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an efficient bag filter to solve the technical problems mentioned in the above background art.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] An efficient bag filter includes a filter bag and a cage. The cage is inserted into the filter bag. The cage is composed of a top ring and a support frame.

[0015] 2. In this type of high-efficiency bag dust collector, the support frame is fitted with the inner wall of the bag, so that when the bag is placed in the bag hole of the dust collector, it is prevented from bending due to the scratches on the side of the bag hole of the dust collector, thereby causing the bag to curl up in the bag hole of the dust collector, thereby affecting the quality of installation and further affecting the work of the bag;

[0016] 3. In this efficient bag filter, the clamping blocks, positioning blocks, and clamping rods are all arc-shaped and have the same arc as the inner ring groove, enabling the clamping blocks and positioning blocks to rotate within the inner ring groove.

[0023] The following will further elaborate on the present invention in detail with reference to the accompanying drawings.

[0024] Embodiment:

[0025] Refer to Figures 1 - 3, an efficient bag 1 dust collector disclosed by the present utility model includes a bag 1 and a cage 2. The cage 2 is inserted into the bag 1. The cage 2 is composed of a top ring 3 and a support frame 4. The top ring 3 is fixedly installed at the top end of the support frame 4. An inner ring groove 5 and an outer ring groove 6 are formed on the bottom side of the top ring 3. A clamping member 7 is arranged in the inner ring groove 5, and an auxiliary member 8 is arranged in the outer ring groove 6;

[0026] The clamping member 7 includes a clamping block 9, a positioning block 10 and a clamping rod 11. The number of the clamping blocks 9 is several and they are fixedly installed on the top side wall of the inner ring groove 5 in a circumferential array distribution. A clamping groove 12 is formed on the top side of the clamping block 9. The number of the clamping rods 11 corresponds to the number of the clamping blocks 9. The clamping rods 11 are clamped in the corresponding clamping grooves 12. The number of the positioning blocks 10 corresponds to the number of the clamping blocks 9. The positioning blocks 10 are fixedly installed on the top side wall of the bag 1. The positioning blocks 10 are inserted into the inner ring groove 5. The end of the positioning block 10 is fixedly connected to the end of the corresponding clamping rod 11.

[0027] In this embodiment, when disassembling the bag 1, the original bag 1 is taken out. The new bag 1 is directly sleeved on the cage 2. Subsequently, the positioning blocks 10 on the top side of the bag 1 are inserted into the inner ring groove 5 of the top ring 3, and the cage 2 is rotated so that the clamping rods 11 are inserted into the clamping grooves 12 to make the clamping rods 11 clamped with the clamping grooves 12. At this time, the connection between the bag 1 and the cage 2 is completed. Subsequently, the bag 1 is directly inserted into the hole for installing the bag 1 of the bag 1 dust collector through the guidance of the cage 2. Although the bag 1 is flexible, it will not bend due to the support of the cage 2, thus avoiding the bending of the bag 1 when the bag 1 is inserted into the hole for installing the bag 1 of the dust collector, and further greatly improving the installation of the bag 1. Subsequently, when the top ring 3 on the top side of the cage 2 fits to the side of the hole for installing the bag 1 of the bag 1 dust collector, automatic positioning is carried out through the auxiliary member 8 at this time, thus saving the step of aligning the edge of the hole for the bag 1 to be docked, further improving the installation efficiency of the bag 1, achieving the effect of saving the time for replacing the bag 1, improving the efficiency of replacing the bag 1, avoiding affecting the working progress of the bag 1 dust collector, and thus affecting the efficiency of the bag 1 dust collector.

[0028] In a further preferred embodiment of the present utility model, as Figures 1 - 2 shown, the inner peripheral wall of the bag 1 is attached to the outer side wall of the support frame 4.

[0029] In this embodiment, the support frame 4 is arranged to be attached to the inner peripheral wall of the bag 1, so that when the bag 1 is placed in the hole for the bag 1 of the dust collector, the bag 1 is prevented from bending due to rubbing against the side of the hole for the bag 1 of the dust collector, and then the bag 1 is curled in the hole for the bag 1 of the dust collector, thus affecting the installation quality and further affecting the operation of the bag 1.

[0030] In a further preferred embodiment of the present invention, Figures 1 - 2 As shown, the clamping block 9 , the positioning block 10 and the clamping rod 11 are arranged in an arc shape, and the arc corresponds to the arc of the inner ring groove 5 .

[0031] In this embodiment, the clamping block 9, the positioning block 10 and the clamping rod 11 are all arranged in an arc shape, and the arc is equal to the arc of the inner ring groove 5, so that the clamping block 9 and the positioning block 10 can rotate in the inner ring groove 5, thereby facilitating the positioning block 10 to drive the clamping rod 11 to be inserted into the clamping groove 12, so that the cloth bag 1 can be clamped on the top ring 3, thereby achieving the effect of quickly installing the cloth bag 1.

[0032] In a further preferred embodiment of the present invention, Figures 1 - 2 As shown, the auxiliary component 8 includes a number of positioning springs 13, and the positioning springs 13 are fixedly mounted on the top side wall of the outer ring groove 6. A magnetic ring 14 is provided at the opening of the outer ring groove 6, and the top side of the magnetic ring 14 is fixedly connected to the positioning spring 13.

[0033] In this embodiment, the positioning spring 13 is used to install the magnetic ring 14. After the bag cage 2 drives the cloth bag 1 to be inserted into the hole of the dust collector cloth bag 1, the top side wall of the cloth bag 1 will fit the edge of the hole of the dust collector cloth bag 1. At this time, the magnetic ring 14 will be squeezed toward the edge of the hole of the dust collector cloth bag 1 through the adsorption force, and then squeeze the top side wall of the cloth bag 1, so that the top side wall of the cloth bag 1 can fit the edge of the hole of the dust collector cloth bag 1, thereby omitting the step of docking the cloth bag 1 and ensuring its sealing and stability after installation;

[0034] When removing the bag 1, directly pull the bag cage 2 so that the bag cage 2 drives the magnetic ring 14 away from the edge of the hole of the dust collector bag 1. At this time, the magnetic ring 14 returns to its original position, and the bag cage 2 will drive the bag 1 to be pulled out of the hole of the dust collector bag 1, thereby achieving the disassembly effect.

[0035] In a further preferred embodiment of the present invention, Figures 1 - 2 As shown, the positioning springs 13 are distributed in an annular array, and the bottom side of the magnetic ring 14 is aligned with the bottom side of the top ring 3 .

[0036] In this embodiment, the springs are arranged in a circular array, so that when the magnetic sheet is adsorbed and squeezed toward the edge of the hole of the dust collector bag 1, all the springs are evenly stressed, avoiding uneven distribution of the springs, which may cause the magnetic ring 14 to tilt when the spring is stretched by the magnetic ring 14, thereby causing gaps in the positioning of the magnetic ring 14, affecting the dust removal effect of the dust collector of the bag 1.

[0037] In a further preferred embodiment of the present invention, Figures 1 - 2As shown, a ring-shaped pad 15 is fixedly connected to the bottom of the top side wall of the cloth bag 1, and the ring-shaped pad 15 is made of rubber or silica gel material.

[0038] In this embodiment, the provided ring-shaped pad 15 is used to protect the top side wall of the cloth bag 1, avoiding the friction between the top side wall of the cloth bag 1 and the edge of the hole of the dust collector cloth bag 1, thereby causing damage to the cloth bag 1 and further affecting the service life of the cloth bag 1.

[0039] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
