Description

Technical Field

[0001] The utility model belongs to the technical field of filtering equipment and relates to a quick-opening device for a filter, in particular to a quick-opening structure for a bag filter. Background Art

[0002] Bag filters are a type of multi-purpose filtration equipment that features a novel structure, small size, simple and flexible operation, energy saving, high efficiency, airtight operation, and strong applicability. Bag filters are a new type of filtration system. A metal mesh basket supports the filter bag inside the bag filter. Liquid flows in through the inlet, passes through the filter bag, and flows out through the outlet. Impurities are trapped in the filter bag, allowing continued use after the bag is replaced. However, in actual operation, bag filter bag replacement is usually done manually. Existing bag filters are usually fixed with multiple sets of screws, and workers need to remove all of the screws before replacing the filter bag, which is time-consuming. Furthermore, the connection between the filter and the filter bag is prone to side leakage when the water pressure is too high. Summary of the Invention

[0003] The purpose of the utility model is to provide a bag filter quick-opening structure to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bag filter quick-opening structure, comprising a cylindrical main body, a partition is fixedly installed on the upper part of the interior of the main body, the upper end of the partition is provided with several groups of threaded holes, and sealing cylinders are installed inside the several groups of threaded holes, the outer wall of the sealing cylinder is provided with external threads, the threaded holes are matched with the external threads, a handle is fixedly installed on the upper end of the sealing cylinder, and a filter bag is fixedly installed on the lower end of the sealing cylinder.

[0005] When using the quick-opening structure of the bag filter, two sets of sealing strips are put on the connection between the main body and the upper cover, so that the upper limit plate and the lower limit plate are stuck in the sealing groove, and one set of movable blocks is rotated around the rotating shaft to make the threaded rod stuck in the slot, and then the nut is screwed onto the threaded rod. The same is true for the other side. Then the two sets of nuts are rotated at the same time and tightened onto the threaded rod. The nuts can be stuck on one side of the slot, so that the two sets of sealing strips are tightened, thereby fixing the upper cover and the main body. When replacing the filter bag, first open the upper cover, hold the handle with your hand, rotate the sealing cylinder along the threaded hole, lift out the entire filter bag, and then put in a new filter bag. The operation is simple and easy to replace.

[0006] As an optimal technical solution of the present invention, a lower limit plate is provided at the upper end of the main body, an upper cover is placed at the upper end of the lower limit plate, and an upper limit plate is provided at the lower end of the upper cover, and the upper limit plate and the lower limit plate are concentrically matched; by providing the upper limit plate and the lower limit plate, one side of the upper limit plate and the lower limit plate are both set as inclined surfaces, and when the sealing strip contracts, the inclined surface can be squeezed so that the upper cover can be more firmly fixed on the main body.

[0007] As an optimal technical solution of the present invention, two sets of sealing strips are wrapped around the outer walls of the upper limit plate and the lower limit plate, and a sealing groove is opened on the inner side of the sealing strip. The upper limit plate and the lower limit plate are embedded in the sealing groove.

[0008] As a preferred technical solution of the present invention, a rotating shaft is fixedly installed at one end of the sealing strip, the sealing strip is rotatably connected to a movable block via the rotating shaft, and a threaded rod is fixedly installed at one end of the movable block.

[0009] As an optimal technical solution of the present invention, a nut is rotatably installed at the end of the threaded rod, and a slot is provided at the other end of the sealing strip, which is adapted to the diameter of the threaded rod; by providing the slot, one side of the slot can allow the threaded rod to pass through, and the diameter of the nut is larger than the slot, so that the two sets of sealing strips can be fixed when the nut is tightened.

[0010] As an optimal technical solution of the present invention, a water outlet is provided at the center of the lower end of the main body, a water inlet is fixedly installed on one side of the outer wall of the main body, and a pressure gauge is fixedly installed on the upper end of the upper cover; by providing a pressure gauge, the pressure inside the main body can be monitored in real time.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. Two sets of sealing strips are used to replace the traditional multiple sets of screws to fix the upper cover and the main body. You only need to tighten the nuts at both ends to reduce the distance between the two sets of sealing strips to fix the upper cover of the filter. When disassembling, you only need to remove one set of nuts to remove the upper cover. The installation and disassembly are particularly simple and reduce manual operation.

[0013] 2. There is a threaded hole on the partition inside the main body. The filter bag is fixed to the upper end of the partition through the cooperation of the threaded hole and the external thread. When the pressure inside the main body is too high, the threaded hole can also effectively prevent side leakage. BRIEF DESCRIPTION OF THE DRAWINGS
