Description

Technical Field

[0001] This invention relates to the field of filter cartridge technology, specifically to an environmentally friendly filter cartridge. Background Technology

[0002] A filter cartridge is a cylindrical element used for filtration, generally divided into those for filtering gaseous media and those for filtering liquid media. Filter cartridges for filtering liquid media are typically installed inside pipeline filters and are commonly conical in shape, hence also called conical filter screens. Filter cartridges for filtering gaseous media are surface filtration elements; they utilize the tiny permeable structures formed on the surface of the filter media to block particulate matter in the gas. Filter cartridges are a commonly used dust collection device, characterized by high collection efficiency, low resistance, and ease of placement in flue gas ducts for sampling. They are widely used for sampling pollutants such as particulate matter, cooking fumes, asphalt fumes, chromic acid mist, and sulfuric acid mist. According to material, they can be divided into glass fiber filter cartridges and corundum filter cartridges, with glass fiber filter cartridges being the most widely used in daily applications. Glass fiber filter cartridges are made of ultra-fine glass fibers and can achieve a collection efficiency of over 99.9% for dust particles larger than 0.5μm. Filter cartridge dust collectors are composed of filter cartridges as filtration elements or employ pulse jet cleaning. Filter cartridge dust collectors can be classified according to installation method as inclined insertion type, side-mounted type, suspended type, and top-mounted type. Based on the filter cartridge material, cartridge dust collectors can be divided into long fiber polyester cartridge dust collectors, composite fiber cartridge dust collectors, anti-static cartridge dust collectors, flame-retardant cartridge dust collectors, membrane-coated cartridge dust collectors, and nano-cartridge dust collectors, etc.

[0003] Since the filter cartridges are made of filter paper or iron and are mostly hollow inside, they are easily deformed when subjected to external pressure. In addition, the filter cartridges are large and inconvenient to carry and transport. Furthermore, the unusable filter cartridges that are replaced later need to be compressed and destroyed. Summary of the Invention

[0004] The problem this invention aims to solve is that the filter cartridge is bulky, inconvenient to carry during processing and use, and requires secondary compression for later transportation and disposal.

[0005] To solve the above technical problems, the technical solution of the present invention is: an environmentally friendly filter cartridge, including a base, a folding tube on the top of the base, the folding tube being able to be folded up and down for compression and unfolding, a cavity inside the folding tube, a support structure on the top of the base, and an anti-foaming structure on the support structure, the anti-foaming structure being able to be used in conjunction with the support structure;

[0006] The top of the folding tube is provided with a connecting ring, and both sides of the connecting ring are provided with magnetic blocks. A fixing screw passes through one side of the magnetic block, and a handle is provided at the bottom of one side of the magnetic block. After the folding tube is folded, the magnetic blocks can be connected to the base.

[0007] Preferably, the support structure includes a connecting rod, a threaded rod, a filter disc, a connecting seat, a fixing rod, a movable cover, a filter hole, a limiting screw, and an arc-shaped plate. The top of the base is provided with a connecting seat, and both sides of the top of the connecting seat are provided with arc-shaped plates. A limiting screw passes through one side of the arc-shaped plate.

[0008] Preferably, the top of the connecting seat is provided with a fixing rod, the top of the fixing rod is provided with a threaded rod, there are two threaded rods, a connecting rod is provided at the middle part of the two threaded rods opposite each other, and a filter plate is provided on the threaded rod, the interior of the filter plate is hollow.

[0009] Preferably, the filter disc has filter media inside, and the top and bottom of the filter disc are provided with a number of filter holes in a circumferential array. A movable cover is provided on one side of the top of the filter disc, and the movable cover can rotate around the center of the filter disc at the rotatable connection point.

[0010] Preferably, the defoaming structure includes a support column, a retaining ring, a float, a fixing spike, a rotating rod, a button, a slider, and a motor. The bottom of the support column is fixedly connected to the top of the threaded rod, and the top of the support column is provided with a fixing seat. The top of the fixing seat is fixedly connected to a connecting pipe, and the motor is located inside the fixing seat.

[0011] Preferably, the support column is provided with a retaining ring, and there are rotating rods on both sides of the retaining ring. Several fixing spikes are arranged at equal intervals on the front of the rotating rods. The retaining ring can be rotated by a motor.

[0012] Preferably, a groove is provided on one side of the support column, a slider is provided inside the groove, a float is provided on one side of the slider, and a button is provided on the top of one side of the support column, the button being electrically connected to the motor.

[0013] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0014] (1) The base is equipped with a support structure, which can be used in conjunction with the folding cylinder. The folding cylinder is foldable and can be folded into a compressed state when not in use. When the folding cylinder and the support structure are assembled together, the support structure can unfold the folding cylinder without shrinking back, and can also add a support force to the inside of the folding cylinder, making the inside of the folding cylinder more robust and stable, and will not deform too much when squeezed. The support structure is also equipped with a filter disc and a threaded rod. The filter disc can be adjusted up and down by the threaded rod. The distance between the two filter discs can be adjusted according to the actual use, further increasing the adjustability of the inside of the folding cylinder. The inside of the filter disc is hollow and can be used to place different filter media according to the use environment. When the filter media is used for a long time, it can be replaced by opening the movable cover. It is more robust and durable, recyclable and more environmentally friendly.

[0015] (2) The support structure is also equipped with a defoaming structure. The defoaming structure can eliminate the foam generated when filtering water impurities by autonomously controlling the float. When water impurities pass through the filter cylinder, the water level line will control the float to move upward. After the float moves to the limit position, the motor will be started by the button. The motor controls the fixed spikes to rotate and eliminate the foam on the water level line, preventing the foam from accumulating upward and causing impurities to overflow and cause further pollution. The fixed spikes themselves have a relatively simple structure and can be quickly cleaned during later maintenance without leaving any impurities. The support structure and the defoaming structure are simple and reliable as a whole. Long-term and efficient filtration can be achieved by replacing the folded cylinder. Attached Figure Description

A connecting rod 901 is provided in the middle of the two threaded rods 902 at opposite ends. A filter disc 903 is provided on the threaded rod 901. The interior of the filter disc 903 is hollow.

[0038] The filter disc 903 has filter media inside. The top and bottom of the filter disc 903 are provided with a number of filter holes 907 in a circumferential array. A movable cover 906 is provided on one side of the top of the filter disc 903. The movable cover 906 can rotate with the filter disc 903 rotatably connected to it.

The top of the fixing seat 2 is fixedly connected to a connecting pipe 1. The motor 808 is located inside the fixing seat 2.

[0040] The support column 801 is provided with a retaining ring 802. Both sides of the retaining ring 802 are provided with rotating rods 805. Several fixing spikes 804 are arranged at equal intervals on the front of the rotating rods 805. The retaining ring 802 can be controlled to rotate by a motor 808.

[0042] The working principle and usage process of this invention are as follows: First, place the base 6 on the ground with the connecting seat 904 facing upwards. Then, align the bottom of the fixing rod 905 with the arc-shaped plate 909 on top of the connecting seat 904. After alignment, insert the fixing rod 905 into the arc-shaped plate 909. After insertion, rotate the limiting screw 908 to fix the fixing rod 905. After fixing, grasp the handles 4 on both sides of the connecting ring 7 and pull upwards until the connecting ring 7 aligns with the bottom of the fixing seat 2. After alignment, the connection is complete. The magnetic block 3 on ring 7 will mate with the fixed base 2. After mating, rotate the fixing screw 10 to fix the fixed base 2 and the connecting ring 7. As the connecting ring 7 is pulled upward, it will cause the folding cylinder 5 to extend and open upward. After opening, it will pass through the filter disc 903. The filter disc 903 will fit against the inside of the folding cylinder 5 to provide support. The filter disc 903 can also replace the filter media inside according to filtration needs. When replacing, simply rotate the movable cover 906 around the rotation connection point with the filter disc 903 as the center. Open the filter media and place it inside. After placing the media, connect the connecting pipe 1 to the water to be filtered. The filter disc 903, together with the folded cylinder 5, can perform dual filtration. When the water is being filtered, the water level will rise, causing the float 803 to move upward. Under buoyancy, the float 803 will cause the slider 807 to move vertically upward along the groove. When the float 803 touches the button 806, the button 806 will control the motor 808 to open. The motor 808 will drive the support column 801 to rotate, which in turn will drive the retaining ring 802 to rotate. The retaining ring 802 will control the rotating rod 805 to rotate. As the rotating rod 805 rotates at high speed, it will defoam the bubbles and foam in the folded cylinder 6 through the fixing spikes 804 on its surface, preventing foam from accumulating at the top of the folded cylinder 5. When the folded cylinder 6 needs to be replaced after long-term use, it should be removed from the connecting seat 904, refolded, and then reinstalled for further processing. After processing, the new folded cylinder 6 can be used again.
