Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquid filtration, in particular to a liquid filter bag capable of preventing damage. BACKGROUND

[0002] The liquid filter bag is an indispensable device on the sewage conveying pipeline, and is usually installed at the water outlet of the sewage pipeline. Since large particles or heavy impurities are mixed in the sewage, the existing liquid filter bag is not convenient for buffering the large particles or heavy impurities in the sewage when filtering the sewage. The large particles or heavy impurities will directly impact the bottom of the filter bag under the action of water flow pressure, which can easily cause damage to the filter bag, and the service life of the filter bag is relatively low. In addition, the existing liquid filter bag usually uses a bunching rope or a hook to install the filter bag on the sewage pipeline, and such an installation method has poor stability of the filter bag, and the filter bag is prone to falling off under the action of water flow washing pressure. SUMMARY

[0003] The present application aims to provide a liquid filter bag capable of preventing damage, so as to solve the problems of the existing liquid filter bag being inconvenient for buffering large particles or heavy impurities in the sewage when filtering the sewage, and the filter bag being prone to falling off under the action of water flow washing pressure.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a liquid filter bag capable of preventing damage, comprising a water inlet pipe,

[0005] The outer side of the water inlet pipe is fixed with a fixed plate, and the bottom of the water inlet pipe is sleeved with a filter bag. The inside of the filter bag is provided with a conical buffer net at the top, and the bottom of the conical buffer net is provided with a discharge port. The bottom of the conical buffer net is an elastic and stretchable structure. The inside of the filter bag is provided with a partition net at the bottom, and the partition net is inclined.

[0006] The bottom of the fixed plate is slidably connected with a movable plate at both ends, and the movable plate is fixed with a clamping plate.

[0007] The fixed plate is provided with a driving assembly, which is used to drive the movable plate and the clamping plate to move horizontally.

[0008] By using the above technical scheme, when the sewage enters the inside of the filter bag from the water inlet pipe, the conical buffer net can filter and buffer the large particles and heavy impurities in the sewage, so as to avoid the impact of the large particles and heavy impurities on the bottom of the filter bag, thereby preventing the filter bag from being damaged and improving the service life of the filter bag.

[0009] Secondly, when installing the filter bag, first, the filter bag is sleeved on the bottom of the water inlet pipe, and then the two groups of movable plates and the clamping plates can be driven by the driving assembly to approach each other, so that the two groups of clamping plates press and fix the filter bag on the bottom of the water inlet pipe. This fixing method can tightly press and fix the filter bag on the bottom of the water inlet pipe, so that the filter bag is not easy to fall off after being washed by water flow, and the stability of the filter bag after installation is improved.

[0010] Preferably, the bottom of the fixing plate is fixed with a U-shaped support at both ends, and the side and bottom of the filter bag are fixed with a buckle at both ends.

[0011] By adopting the above technical scheme, the U-shaped support can lift the bottom of the filter bag, and the buckle can prevent the filter bag from falling off the U-shaped support, so as to prevent the filter bag from stretching and falling due to too much impurity in the filter bag, and prevent the filter bag from tearing due to excessive weight.

[0012] Preferably, the bottom of the conical buffer net is sleeved with an elastic ring, and the conical buffer net and the elastic ring are connected by ultrasonic pressing.

[0013] By adopting the above technical scheme, the elastic ring can bind the bottom of the conical buffer net, so that large particles and large weight impurities can slowly fall on the separation net, and also prevent the bottom of the conical buffer net from relaxing.

[0014] Preferably, the side of the filter bag is provided with a notch, and the notch is flush with the bottom of the separation net. The outer side of the notch is sleeved with a blocking net, and the blocking net is adhered to the outer wall of the filter bag by magic tape.

[0015] By adopting the above technical scheme, when the large particles and large weight impurities on the separation net are too much, the blocking net can be easily torn by magic tape, so that the impurities on the separation net can be scraped out from the notch for cleaning. The technical scheme has simple structure and convenient operation, and is convenient for cleaning the impurities to dredge the separation net, improving the convenience in use.

[0016] Preferably, the side of the clamping plate is provided with an arc-shaped groove, and a plurality of rubber cones are fixed in the arc-shaped groove.

[0017] By adopting the above technical scheme, the arc-shaped groove on the clamping plate can fit the outer wall of the water inlet pipe, and the rubber cone in the arc-shaped groove can improve the clamping effect on the filter bag without damaging the filter bag.

[0018] Preferably, the driving assembly comprises a hand wheel, the hand wheel is installed on the outer side of the fixed plate, and the two ends of the fixed plate are respectively provided with an empty slot one and an empty slot two, a screw rod is installed in the empty slot one, and a movable block is threadedly connected to the screw rod, the bottom of the movable block is provided with connecting rods, and the two ends of the connecting rods are respectively rotatably connected to the movable block and the movable plate, and a guide assembly is arranged in the empty slot two.

[0019] By adopting the above technical scheme, after the filter bag is sleeved on the bottom of the water inlet pipe, the hand wheel is rotated to drive the screw rod to rotate, the screw rod drives the movable block to move in the empty slot one away from the axis of the water inlet pipe, at this time, the two ends of the two connecting rods are respectively rotated on the movable block and the movable plate, and drive the two movable plates and the clamping plates to move close to each other, so that the clamping plates press and fix the filter bag on the bottom of the water inlet pipe.

[0020] Preferably, the guide assembly comprises a fixed rod, the fixed rod is fixed in the empty slot two, and sleeves are sleeved on the two ends of the fixed rod, the sleeve is connected with the movable plate, and a plurality of balls are arranged on the inner wall of the sleeve.

[0021] By adopting the above technical scheme, when the movable plate moves transversely, it drives the sleeve to slide on the fixed rod, the fixed rod plays a role in transversely guiding the movable plate and the clamping plate, and the balls on the inner wall of the sleeve can reduce the friction when the sleeve slides on the fixed rod, thereby reducing wear and tear and prolonging service life.
