AI Technical Summary
When using the existing filter bag, the overall length of the filter bag is adjusted by setting an assembly structure. However, since the assembly structure is located inside the filter bag, it is difficult for operators to directly observe the internal connection state, which increases the difficulty of operation and is not conducive to rapid adjustment of the filter bag length.
A multifunctional composite polyester filter bag including an end bag body, an intermediate bag body and a tail bag body is designed. By installing No. 1 and No. 2 connection mechanisms on the top and bottom of the middle bag body, the magnetic adsorption, locking structure and the coordination of positioning piles and positioning holes are used to achieve stable connection and length adjustment between the bag body.
Through the external connection structure, the operator can directly observe and operate the connection state between the bags, reducing the difficulty of operation, improving work efficiency, and making the adjustment of the filter bag length faster and more convenient.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filter bags, and particularly relates to a multifunctional composite polyester filter bag with adjustable length. Background Art
[0002] Polyester filter bags are a kind of efficient and durable filtration products, which are carefully woven from polyester fibers (polyester). It has excellent high temperature resistance, corrosion resistance and wear resistance, and can work stably in harsh industrial environments. The fiber structure of the polyester filter bag is tight, which can effectively capture tiny particulate matters and ensure that the filtered liquid or gas reaches a high-quality purity. In addition, the polyester filter bag also has good air permeability and easy cleanability, and can maintain a stable filtration effect for a long time. Whether in industries such as chemical industry, pharmaceutical industry, food industry or environmental protection, polyester filter bags are ideal filtration solutions.
[0003] When some existing filter bags are in use, the overall length of the filter bag is adjusted by setting an assembly structure, but the assembly structure is located inside the filter bag, and it is difficult for operators to directly observe the internal connection state during disassembly and assembly, which increases the operation difficulty and is not conducive to quickly adjusting the length of the filter bag.
[0004] For example, a dust removal filter bag that is easy to disassemble disclosed in the patent with the publication number CN217746218U. The filter bag of this patent forms a framework for supporting the filter bag by setting a top frame, a bottom frame and an annular frame, and installs the filter bag on the annular frame and the bottom frame respectively. The top frame, the bottom frame and the annular frame are connected by setting a limit pin and a limit groove, and are further fixed by a fixed slot and a fixed block. Due to the same connection structure, the appropriate number of annular frames can be selected according to the dust removal needs to form a filter bag body of different lengths and sizes to meet different dust removal requirements of different intensities.
[0005] Since the framework and the fixing structure of the dust removal filter bag are mainly located inside the filter bag, it is difficult for operators to directly observe the internal connection state during assembly and disassembly, which increases the operation difficulty and also increases the risk of improper assembly or incomplete disassembly, and is not conducive to quickly adjusting the length of the filter bag.
[0006] Therefore, it is necessary to invent a multifunctional composite polyester filter bag with adjustable length to solve the above problems. Content of the Utility Model

[0010] Preferably, a rubber sealing ring is fixedly connected to the top of the first annular carrier plate, and a rubber sealing groove is fixedly embedded at the bottom of the second annular carrier plate.

[0012] Preferably, a first end block is fixedly connected to the outside of the first annular carrier plate, and a positioning pile is fixedly connected to the top of the first end block.
[0013] Preferably, a second end block is fixedly connected to the outside of the second annular carrier plate, and a positioning hole is formed on the surface of the second end block.
[0014] The positioning pile on the first end block matches the positioning hole on the second end block, ensuring the accurate docking between the bag bodies and improving the connection stability.
[0015] Preferably, a mounting plate is fixedly connected to the top of the head bag body, and a second connecting mechanism is also installed at the bottom of the head bag body.
[0016] With the cooperation of the first connecting mechanism and the second connecting mechanism, the head bag body and the middle bag body can be assembled together.
[0017] Preferably, a blanking valve pipe is fixedly connected to the bottom of the tail bag body, and a first connecting mechanism is also installed at the top of the tail bag body.

[0019] Preferably, the adjacent first connecting mechanism and the second connecting mechanism are matched with each other. The first magnetic attraction ring and the second magnetic attraction ring are fixed together by magnetic attraction. The latch moving part and the latch fixing part are latched together. The rubber sealing ring and the rubber sealing groove are engaged with each other. The positioning pile and the positioning hole are inserted into each other.

[0036] Working principle of the utility model:
[0037] Refer to the attached drawings of the specification Figures 1-5 When using the utility model, first fix the end head bag body 1 under the exhaust pipe through the mounting plate 18 to ensure that the mounting plate 18 is tightly connected to the exhaust pipe to prevent air leakage;
[0038] Place a middle bag body 2 at the bottom of the end head bag body 1 to ensure that the positioning pile 15 on the first annular carrier plate 6 is aligned with the positioning hole 17 on the second annular carrier plate 9 and inserted together. Through the magnetic attraction of the first magnetic attraction ring 7 and the second magnetic attraction ring 10, initially fix the middle bag body 2 at the bottom of the end head bag body 1. Flip the buckle moving part 8 upward to make it buckled with the buckle fixing part 11 to further fix the connection between the middle bag body 2 and the end head bag body 1. At this time, the rubber sealing ring 12 is tightly clamped with the rubber sealing groove 13 to ensure the airtightness of the joint;
[0039] Repeat the above steps and continue to assemble multiple middle bag bodies 2 together from bottom to top in sequence to ensure that the connection between each middle bag body 2 is firm and airtight. According to actual needs, adjust the total length of the filter bag by increasing or decreasing the number of middle bag bodies 2 to meet different filtration requirements;
[0040] Place the tail end bag body 3 under the last middle bag body 2 and fix the tail end bag body 3 at the bottom of this middle bag body 2 through the cooperation of the first connecting mechanism 4 and the second connecting mechanism 5;
[0041] When the pipeline discharges high-temperature waste gas into the inside of the filter bag, the gas passes through the filter bag and escapes outward, while the particulate matter in the gas is intercepted inside the filter bag. Since the outer surface of the filter bag is coated with a waterproof coating, it can prevent the moisture in the external environment from invading the inside of the filter bag, prevent the particulate matter from caking inside the filter bag, and facilitate subsequent cleaning. The inner surface of the filter bag is coated with a heat-resistant coating, which can prevent the high-temperature waste gas from scalding the filter bag and is conducive to extending the service life of the filter bag;
[0042] Regularly check and clean the particulate matter intercepted inside the filter bag to maintain the filtration efficiency of the filter bag. The particulate matter attached to the inner side of the filter bag is made to fall off by patting the filter bag, and the particulate matter is discharged from the inside of the filter bag through the blanking valve pipe.
