Description

Technical Field

[0001] The present invention relates to the technical field of filters, in particular to a filter capable of preventing filter pores from being clogged. Background Art

[0002] A filter is a device that captures dust from a gas-solid two-phase flow through a porous filter material, purifying the gas. When the filter is in use, particulate matter in the air can easily clog the filter element, causing damage and requiring repair or even replacement, increasing costs. In practice, a pre-filter is often installed to perform preliminary air filtration and reduce the filter's workload. However, the filter element can still easily clog, affecting the filter's continued filtration effectiveness.

[0003] In the prior art, a filtering anti-clogging component is used, and the air filter part is sucked by an exhaust fan, and then the dust flows into the dust collecting seat. In this method, filtering is only performed through the air filter part, and the filtering capacity is weak, which cannot meet the rapid filtering needs of high sand and high dust environments, and an additional exhaust fan is required. It is impossible to use the power of the airflow for automatic cleaning, which increases the cost; an electric heating component is used to heat the filter material to prevent moisture in the air from affecting the filtering efficiency of the filter material. In this method, moisture in the air cannot be removed during the filtering process, which reduces the filtering effect on the air and cannot provide clean air for subsequent work.

The particles in the air are negatively charged by the negatively charged mesh, and the part of the screen at the outlet pipe is positively charged by the brush. The mesh of the screen is blocked and electrostatically adsorbed, thereby improving the removal intensity of the particles in the air and meeting the filtering requirements of high sand and high dust air. When the screen at the outlet pipe is blocked by attached particles, the airflow bypasses the wind trough and drives the screen to rotate by the self-regulating mechanism to ensure the continuous filtering effect of the screen. At the same time, a negative pressure suction effect is formed on the screen rotated to the air inlet pipe, which promotes the particles to fall from the screen, ensures the smooth flow of the screen, improves the service life of the screen, reduces the cycle of cleaning the screen for the staff, and reduces the cleaning burden of the staff.

[0022] 2. The present invention provides a heating rod and a cooling plate. When multiple storage boxes are running inside the air duct, the water adsorbed by the desiccant in the storage box is desorbed and evaporated by the heating of the heating rod, and is quickly condensed by the cooling plate, flows into the outlet pipe along the top and inner wall, and is collected into the inside of the water collection bag, so that the desiccant can be used continuously and the water absorption effect is maintained. At the same time, water is collected for backup in water-scarce environments such as deserts. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0032] Reference Figures 1-4 A filter for preventing filter pores from being clogged comprises a housing 2, wherein the top of the housing 2 is fixedly connected to an upper cover 1, the bottom is threadedly connected to a lower cover 4, the side of the housing 2 is connected to an air outlet pipe 21, and the upper cover 1 is connected to an air inlet pipe 11, and further comprises:

[0033] The screen 5 is rotatably connected to the interior of the housing 2 , and the air inlet pipe 11 is communicated with the interior of the screen 5 .

[0034] The shell 2 and the screen 5 are both cylindrical and non-coaxially arranged. Bearing 23 is installed between the top and bottom of the screen 5 and the shell 2. A rubber pad 24 is sealed and fixed between the bearing 23 and the shell 2.

[0035] The second bearing 23 reduces the rotational resistance of the screen 5 inside the housing 2, making it easier for the screen 5 to rotate when required in subsequent work, thereby ensuring the continuous filtering effect of the screen 5.

[0036] The rubber pad 24 ensures sealing and insulation, preventing air from directly passing through the gap between the screen 5 and the shell 2, so that the air entering the shell 2 passes through the mesh of the screen 5, ensuring the filtering effect, and at the same time preventing the screen 5 from being electrified and causing the shell 2 to be electrified during subsequent work, thereby preventing the shell 2 from causing harm to the safety of on-site personnel.

[0037] The air duct 13 has a partition 12 fixedly connected between the outer side of the air duct 13 and the bottom of the upper cover 1 . The partition 12 extends into the interior of the screen 5 and is located between the air inlet pipe 11 and the air outlet pipe 21 . The air duct 13 is connected to both sides of the partition 12 .

[0038] The interior of the screen 5 is roughly divided into left and right parts by the partition 12, and the air entering the interior of the shell 2 through the air inlet pipe 11 is guided through the partition 12 through the air duct 13 on the partition 12, so that the internal structure of the air duct 13 can process the air.

[0039] The filter mechanism is connected to the interior of the air cylinder 13 and is used to filter large particles and moisture in the air.

[0040] The filtering mechanism includes a net 14 and a net 2 15 fixedly connected to the two ends of the air duct 13. The net 14 is close to the air inlet pipe 11, and the net 2 15 is close to the air outlet pipe 21. The end of the air duct 13 away from the air inlet pipe 11 faces the air outlet pipe 21, and the end of the air outlet pipe 21 away from the shell 2 is connected to the external air pump.

[0041] The external air pump works to suck the air inside the screen 5 through the air outlet pipe 21 and the screen 5, so that the air flow quickly passes through the air inlet pipe 11 and the air cylinder 13, providing power for the movement of the subsequent structure.

[0042] Two wind wheels 16 are rotatably connected inside the wind tube 13. The two wind wheels 16 are located between the net 14 and the net 2 15. A connecting ring 19 is fixedly connected to the opposite side of the two wind wheels 16. A plurality of storage boxes 18 are rotatably connected between the two connecting rings 19. Silica gel desiccant is placed inside the storage boxes 18.

[0043] When the airflow passes through the air duct 13 quickly, the airflow drives the wind wheel 16 to rotate, slowing down the flow rate of the airflow through the wind wheel 16 and causing the airflow to swirl inside the air duct 13, so that the air can fully contact the silica gel desiccant inside the storage box 18, thereby fully removing moisture from the air.

[0044] A bearing 17 is installed between the wind wheel 16 and the wind tube 13; the center of gravity of the storage box 18 is located below its rotation point, and an opening is provided on the top of the storage box 18.

[0045] Since the center of gravity of the storage box 18 is located below the rotation point, the storage box 18 always keeps its opening facing upward during the movement of the connecting ring 19, making it easier for the moisture in the silica gel desiccant to be evaporated and overflowed by the subsequent structure.

[0046] Reference Figure 5 The filtering mechanism also includes a dehydration component, which includes a heating rod 112 installed inside the air duct 13 and a refrigeration plate 113 installed on the top of the air duct 13. The bottom of the air duct 13 is connected to a water outlet pipe 31, and the end of the water outlet pipe 31 away from the air duct 13 is sealed and passes through the shell 2, and is connected to a water collection bag 3.

[0047] The heating rod 112 and the cooling plate 113 both adopt existing technology. The heating rod 112 heats the inside of the air duct 13, so that the silica gel desiccant near the heating rod 112 is separated from the water under the action of high temperature, and condenses into small water droplets in the cold zone formed by the cooling plate 113, and finally flows down along the inner side of the air duct 13 and is collected by the water outlet pipe 31 and the water collection bag 3, so as to facilitate the reuse of water.

[0048] The inner side of the air duct 13 is an inner wall 111 and the top is an upper top 110 . The refrigeration fins 113 are mounted on the upper top 110 . The edges of the upper top 110 are all tilted downward and smoothly connected to the inner wall 111 .

[0049] The upper top 110 and the inner wall 111 facilitate the condensed water droplets to slide down the two, thereby improving the collection effect of the water droplets.

[0050] Reference Figure 6 and Figure 7 , self-adjusting mechanism, the self-adjusting mechanism includes a wind wheel 28, the outer side of the screen 5 and the inner side of the shell 2 form a wind groove 27, the wind groove 27 is located on one side of the air outlet pipe 21, and the end is connected to the air outlet pipe 21, the wind wheel 28 is connected to the wind groove 27, and the top and bottom are fixedly connected to the rubber wheel 29, the rubber wheel 29 is against the outside of the screen 5.

[0051] The inner side of the housing 2 is connected to a rotating groove, which is connected to the wind groove 27 . The wind wheel 28 is rotatably connected to the inside of the rotating groove and partially extends into the inside of the wind groove 27 .

[0052] The rotating shaft of the wind wheel 28 is located inside the rotating groove. When the air flow passes through the wind groove 27 and blows towards the part of the wind wheel 28, the wind wheel 28 rotates accordingly, thereby driving the screen 5 to rotate through the rubber wheel 29 to maintain the efficient filtering effect of the screen 5.

[0053] The mesh 2 15 is negatively charged through an electric wire, and the side of the screen 5 close to the air outlet pipe 21 is electrically rotated and contacts with a brush 1 25, and the brush 1 25 is positively charged through an electric wire.

[0054] By connecting the negatively charged mesh 15 and the positively charged part of the screen 5, an electrostatic dust removal effect is formed on the passing air, thereby improving the removal strength of the screen 5 on particulate matter in the air and meeting the filtering needs of high sand and high dust.

[0055] The outer side of the screen 5 is electrically rotated and contacted with a plurality of brushes 26 , which are distributed on a side of the air cylinder 13 away from the air outlet pipe 21 , and the brushes 26 are grounded through wires.

[0056] The bottom of the shell 2 is funnel-shaped, and a discharge port 22 is formed at the bottom end. The lower cover 4 is threadedly connected to the outer side of the discharge port 22 .

[0057] The present invention is applied to the pre-filtration of industrial air pumps in high-sand and high-dust environments such as deserts. When in use, the upper cover 1 and the shell 2 are fixed together by bolts, and the lower cover 4 is connected to the shell 2 by threads.

[0058] The air outlet pipe 21 is connected to an external air pump. When the air pump works, the clean air inside the housing 2 is sucked in by negative pressure through the air outlet pipe 21, and the screen 5 performs air filtering.

[0059] The partition 12 is welded to the bottom of the upper cover 1 and divides the inside of the screen 5 into left and right parts. The outside air passes through the air inlet pipe 11, the left half of the screen 5, the air duct 13 and the right half of the screen 5 in turn, is filtered by the screen 5, and is finally discharged from the air outlet pipe 21.

[0060] When air passes through the air duct 13, mesh 14 and mesh 2 15 are welded to both ends of the air duct 13 respectively. The air passes through mesh 14, the inside of the air duct 13 and mesh 2 15 in sequence. Mesh 14 first blocks large particles such as pebbles in the air to prevent large particles from getting stuck or damaging subsequent components and the screen 5, thereby ensuring the normal service life of the filter.

[0061] A wind wheel 16 is mounted on each side of the wind tube 13 through a bearing 17. When air enters the wind tube 13, the airflow pushes the wind wheel 16 to rotate continuously.

[0062] The rotation of the wind wheel 16 causes the air flow entering the wind tube 13 to swirl, thereby increasing the residence time of the air inside the wind tube 13 and ensuring the contact time between the air and the desiccant. At the same time, the storage box 18 is driven to rotate by the connecting ring 19. Silica gel desiccant is placed in the storage box 18. The storage box 18 is rotatably connected to the connecting ring 19 and always keeps the top of the box facing upward under the action of gravity. The air entering the wind tube 13 contacts the silica gel desiccant in the storage box 18 and has moisture absorbed.

[0063] As the wind wheel 16 rotates, multiple storage boxes 18 rotate back and forth. When the storage boxes 18 reach the heating rod 112, they are affected by the heating, and the moisture in the silica gel desiccant is desorbed, evaporated and floats up. When the water vapor contacts the cooling plate 113 located at the upper top 110, it instantly condenses into water droplets and slides down along the upper top 110 and the inner wall 111 until it enters the inside of the water outlet pipe 31 and is collected in the inside of the water collection bag 3, so that the desiccant can be used continuously, maintain the water absorption effect, and obtain a certain amount of water.

[0064] The mesh 2 15 is negatively charged so that when the dry air passes through the mesh 2 15, the particulate matter in the air carries a negative charge. The side of the screen 5 close to the air outlet pipe 21 is supplied with positive electricity through the brush 1 25. In the process of the air passing through the mesh 2 15 and entering the air outlet pipe 21, the dust and other particulate matter carrying the negative charge are blocked by the mesh of the screen 5 and adsorbed by electrostatics, and are tightly combined with the screen 5, thereby improving the removal intensity of the particulate matter in the air and meeting the filtering needs of high sand and high dust air.

[0065] When there are too many particles adhering to the part of the screen 5 near the outlet pipe 21, the resistance of the screen 5 increases, and the airflow cannot pass through easily. The airflow can only bypass and enter the interior of the outlet pipe 21 from the wind groove 27. When the airflow passes through the wind groove 27, it drives the wind wheel 28 to rotate. The upper and lower ends of the wind wheel 28 are provided with rubber wheels 29. The rotation of the wind wheel 28 causes the rubber wheel 29 to drive the screen 5 to rotate accordingly.

[0066] When the screen 5 rotates a certain angle, the part of the screen 5 blocked by particles moves away from the outlet pipe 21, and the resistance of the screen 5 is reduced, so that the air flow can directly pass through the screen 5 and enter the outlet pipe 21, and the screen 5 stops rotating.

[0067] A grounded brush 26 is provided on the side of the screen 5 away from the air outlet pipe 21 to further ensure that the housing 2 is not electrically charged.

[0068] When the part of the screen 5 carrying the particles moves to the brush 2 26, the screen 5 and the particles are no longer charged, which weakens the bonding strength between the particles and the screen 5, causing some of the particles to fall to the bottom of the shell 2. At the same time, when the air enters the air duct 13 through the air inlet pipe 11, the air inside the wind slot 27 and near the screen 5 is sucked in, forming an airflow recoil effect on the screen 5, further promoting the particles to fall from the screen 5, ensuring the smooth flow of the screen 5, improving the service life of the screen 5, reducing the cycle of the staff cleaning the screen 5, and reducing the cleaning burden of the staff.

[0069] The particles that fall to the bottom of the shell 2 are collected at the discharge port 22 along its funnel-shaped structure. The maintenance personnel can quickly discharge the collected sand and dust and clean the dirt by regularly unscrewing the lower cover 4.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
