[0002] Bag filter is a multi-purpose filtering equipment with novel structure, small size, simple and flexible operation, energy saving, high efficiency, closed working and strong applicability. Bag filter is a new type of filtering system. The filter bag is supported by a metal mesh basket inside the bag filter. The liquid flows in from the inlet and flows out from the outlet after being filtered by the filter bag. Impurities are intercepted in the filter bag and can continue to be used after replacing the filter bag.

[0003] When the existing bag filter is used, the filter bag is first placed inside the bag filter housing, and then the inlet pipe is connected to allow the fluid to enter the bag filter housing, and after being filtered by the filter bag, it is discharged from the outlet pipe.

[0004] Usually, the filter bag is directly placed into the bag filter housing. When the fluid enters the bag filter housing, it has a certain impact on the filter bag, and the filter bag will be offset inside the bag filter housing. In addition, the filter bag is inside the bag filter housing, which makes it difficult for the staff to quickly find abnormalities in the filter bag, thus affecting the effect of fluid filtration.

[0025] In this embodiment, the implementation scenario is specifically as follows: the mounting ring 5 is placed inside the fixing ring 3, so that the T-shaped block 71 is located inside the arc-shaped slide groove 72, and slides along the arc-shaped slide groove 72, so that the block 74 inside the hole on the surface of the T-shaped block 71 is engaged with the groove on the inner wall of the arc-shaped slide groove 72, so that the mounting ring 5 can be fixed.

[0026] For further information, please refer to the attached manual. Figure 5 A support ring 8 is provided on the outside of the filter bag 6, and the support ring 8 is located inside the mounting ring 5. A limiting ring 9 is provided on the inside of the mounting ring 5, and the limiting ring 9 is located at the bottom of the support ring 8. A plurality of fixing rods 10 are provided on the top of the limiting ring 9, and a plurality of fixing holes 11 are opened on the surface of the support ring 8, and the plurality of fixing rods 10 are all engaged with the fixing holes 11.

[0027] In this embodiment, the specific implementation scenario is: align the support ring 8 with the limit ring 9, and clamp the fixing rod 10 with the fixing hole 11, so as to fix the filter bag 6 and the installation ring 5.

[0028] For further information, please refer to the attached manual. Figure 1 A support ring 13 is fixedly provided on the outer side of the shell 1 , a plurality of legs 14 are provided at the bottom of the support ring 13 , and the tops of the plurality of legs 14 are fixedly connected to the surface of the support ring 13 .

[0029] In this embodiment, the specific implementation scenario is: the legs 14 are fixed to the support ring 13 by screws, so as to support the housing 1 .

[0030] For further information, please refer to the attached manual. Figure 1 , 2 A water inlet pipe 15 is provided on one side of the shell 1, and the water inlet pipe 15 is higher than the fixing ring 3 inside the shell 1. A drainage pipe 16 is provided on the other side of the shell 1, and the drainage pipe 16 is located at the bottom of the support leg 14. A sewage pipe 17 is provided at the bottom of the shell 1, and the sewage pipe 17 is located between the multiple support legs 14.

[0031] In this embodiment, the implementation scenario is specifically as follows: the water inlet pipe 15 is connected to transport the fluid into the shell 1, the filtered fluid is discharged through the drainage pipe 16, and the waste generated by the fluid is discharged through the sewage fixation.

[0032] Working principle: First, put the filter bag 6 into the installation ring 5, so that the support ring 8 outside the filter bag 6 is located on the limiting ring 9 inside the installation ring 5, and press the support ring 8 to make the fixing rod 10 on the limiting ring 9 engage with the fixing hole 11 on the surface of the support ring 8, so that the filter bag 6 can be fixed;

[0033] Then pull the arc handle 12, put the installation ring 5 into the top of the fixing ring 3 inside the shell 1, so that the filter bag 6 is located inside the hollow cylinder 4, and place the multiple T-shaped blocks 71 outside the installation ring 5 inside the arc-shaped slide groove 72 on the surface of the fixing ring 3, and then rotate the installation ring 5 to drive the T-shaped block 71 to move along the arc-shaped slide groove 72. The block 74 on one side of the T-shaped block 71 is set to be circular, and when the T-shaped block 71 moves and drives the block 74 to contact the inner wall of the arc-shaped slide groove 72, the block 74 is subjected to pressure to press the spring The spring 73 generates pressure and compresses the block 74, so that the block 74 can be retracted into the hole. The block 74 can slide along the inner wall of the arc-shaped slot 72 by the elasticity of the spring 73. When the T-shaped block 71 moves to the top of the arc-shaped slot 72, the slots of the hole and the inner wall of the arc-shaped slot 72 are in a vertical state. The elasticity of the spring 73 generates a rebound force on the block 74, so that the block 74 can be pushed into the slot and connected with it, so that the mounting ring 5 can be installed inside the fixing ring 3.

[0034] Then, the water inlet pipe 15 is connected to allow the fluid to enter the shell 1, and the fluid is filtered through the filter bag 6, and then the filtered fluid is discharged through the drainage pipe 16, and the sewage is discharged through the sewage pipe 17. The utility model can directly fix the filter bag 6 by connecting the mounting ring 5 and the fixing ring 3 through the clamping block 74 and the clamping groove, and can avoid the staff from stopping the filter to check the filter bag 6, and can avoid the impact force generated when the fluid enters the shell 1, so as to displace the filter bag 6 and avoid affecting the effect of fluid filtration. The precision of fluid filtration can be improved, and the filter bag 6 can be replaced separately by separating the fixing rod 10 and the fixing hole 11 between the limit ring 9 and the support ring 8.

[0035] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
