Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to an industrial automated sewage filtering device. Background Art

[0002] Automated sewage filtration is a process that uses advanced technology and equipment to filter sewage without continuous human intervention to remove solid impurities, suspended matter, some organic matter and other pollutants. In sewage filtration equipment, a variety of sensors are usually installed. If the turbidity exceeds the set value, the system will automatically increase the filtration intensity or remind the staff to check.

[0003] In the actual use process, after a certain period of use, the filter will inevitably be clogged with dirt. The general cleaning method is to stop the machine for cleaning, which affects the working process of sewage filtration and its automation effect in terms of movement. Summary of the invention

[0004] In order to make up for the above deficiencies, the present invention provides an industrial automated sewage filtering device that overcomes the above technical problems or at least partially solves the above problems.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An industrial automation sewage filtering device comprises a first three-way pipe, a second three-way pipe is arranged above the first three-way pipe, a main filtering mechanism and an auxiliary filtering mechanism are respectively arranged on both sides of the first three-way pipe and the second three-way pipe, the main filtering mechanism and the auxiliary filtering mechanism have the same structure and are arranged in a mirror image, the main filtering mechanism and the auxiliary filtering mechanism both comprise a first filter cartridge, a second filter cartridge is arranged at the bottom of the first filter cartridge, a first filter screen is arranged in the first filter cartridge, a second filter screen is arranged in the second filter cartridge, a first cleaning assembly is arranged on the outer circle of the first filter screen, a second cleaning assembly is arranged in the second filter screen, a first water inlet valve and a second water outlet valve are respectively arranged on both sides of the first filter cartridge, a first water outlet valve and a second water inlet valve are respectively arranged on both sides of the second filter cartridge, the first water inlet valve is connected to the transverse pipe body of the first three-way pipe, and the second water inlet valve is connected to the transverse pipe body of the second three-way pipe.

[0007] By setting the first three-way pipe in combination with the second three-way pipe, the main filtering mechanism is generally used for filtering. At this time, the second water inlet valve and the second water outlet valve of the main filtering mechanism are closed, and the industrial sewage enters the main filtering mechanism from the first water inlet valve for filtering. After a certain period of use, when the internal filter needs to be cleaned, the first water inlet valve and the first water outlet valve of the auxiliary filtering mechanism are opened, and the first water inlet valve and the first water outlet valve of the main filtering mechanism are closed at the same time, and the auxiliary filtering mechanism is used for automatic filtering operation, and the filter of the main filtering mechanism is cleaned at the same time, so as to achieve non-stop cleaning, thereby ensuring effective filtration of industrial sewage and non-stop cleaning. Washing ensures that the sewage treatment process can be carried out continuously. In sewage treatment plants and other facilities, sewage is generated continuously, which ensures the automation effect of the device. By setting a second filter screen and combining it with the first filter screen, the two are set vertically. When filtering, the sewage will first flow through the first filter screen and the lower part of the second filter screen. After the relatively lower part of the filter screen is blocked to a certain extent by stains, the liquid level of the water that has not flowed out will rise, and continue to filter from the part of the filter screen that has not played a filtering function before, so that before all-round cleaning is required, there is always a part of unused filter screen on standby, compared to putting the filter screen in full contact with sewage, thus ensuring the water flow rate.

[0008] In one embodiment of the present invention, the first filter cartridge and the second filter cartridge are both provided with a fixing frame, and the fixing frame of the first filter cartridge and the fixing frame of the second filter cartridge are connected via a connecting rod.

[0009] In one embodiment of the present invention, the first filter cartridge has a first structural ring on its body, an inner ring of which is provided with a connecting channel ring, and the second filter cartridge has a second structural ring inside, an inner ring of which is provided with a threaded ring.

[0010] In one embodiment of the present invention, one end of the first filter screen is fixedly connected to one side of the inner wall of the first filter cylinder, the other end of the first filter screen is fixedly connected to one side of the first structural ring, and both ends of the second filter screen are respectively connected to the first structural ring and the opposite sides of the second structural ring.

[0011] In one embodiment of the present invention, the first cleaning assembly includes a slotted ring, a first scraper arranged in a ring array is provided on the side of the slotted ring, the first scraper is fixedly connected to a swivel at one end away from the slotted ring, a first gear is movably provided on the cylinder body of the first filter cartridge, the first gear is meshingly connected with the slot of the outer ring of the slotted ring, a first servo motor is provided on the top of the first filter cartridge through a connecting piece, and the rotating shaft of the first gear is connected to the rotating shaft of the first servo motor.

[0012] In one embodiment of the present invention, the second cleaning assembly includes a threaded shaft, which is threadedly connected to a threaded ring, a first rotating rod is rotatably provided on one side of the threaded ring through a structural ring, one end of the threaded shaft is fixedly connected to a limiting rod movably inserted into the inner ring of the first rotating rod, and the side part of the rod body of the limiting rod is fixedly connected to the limiting protrusion.

[0013] In one embodiment of the present invention, a long through groove matched with the limiting protrusion is opened on the rod body of the first rotating rod, and a second servo motor is provided at the bottom of the second filter cylinder through a structural member, and the output shaft of the second servo motor is connected to the end of the first rotating rod.

[0014] In one embodiment of the present invention, the other end of the threaded shaft is fixedly connected to a second rotating rod, the outer ring of the second rotating rod is fixedly connected to a structural frame, and the end of the structural frame is fixedly connected to a second scraper arranged in an annular manner.

[0015] In one embodiment of the present invention, the inner circle of the first scraper is movably overlapped with the outer circle of the first filter screen, and the outer circle of the second scraper is movably overlapped with the inner circle of the second filter screen.

[0016] In one embodiment of the present invention, both ends of the first three-way pipe are connected to the first water inlet valves of the main filtering mechanism and the auxiliary filtering mechanism, and both ends of the second three-way pipe are connected to the second water inlet valves of the main filtering mechanism and the auxiliary filtering mechanism.

[0017] The invention provides an industrial automated sewage filtering device, which has the following beneficial effects:

[0018] 1. By setting the first three-way pipe and combining it with the second three-way pipe, the main filtering mechanism is generally used for filtering. At this time, the second water inlet valve and the second water outlet valve of the main filtering mechanism are closed, and the industrial sewage enters the main filtering mechanism from the first water inlet valve for filtration. After a certain period of use, when the internal filter needs to be cleaned, the first water inlet valve and the first water outlet valve of the auxiliary filtering mechanism are opened, and the first water inlet valve and the first water outlet valve of the main filtering mechanism are closed at the same time. The auxiliary filtering mechanism is used for automatic filtration operation, and the filter of the main filtering mechanism is cleaned at the same time, so as to achieve non-stop cleaning, which ensures the effective filtration of industrial sewage and ensures that the sewage treatment process can continue. In facilities such as sewage treatment plants, sewage is generated continuously, which ensures the automation effect of the device.

[0019] 2. By setting up a second filter in combination with the first filter, the two are set vertically. When filtering, the sewage will first flow through the first filter and the lower part of the second filter. After the relatively lower part of the filter is blocked to a certain extent by stains, the liquid level of the water that has not flowed out will rise, and continue to filter from the part of the filter that has not played a filtering function before. Before all-round cleaning is required, compared with putting the filter in all-round contact with the sewage, there is always a part of unused filter on standby, ensuring the water flow.

[0020] 3. By setting up the second cleaning component, the second scraper can perform rotary propulsion scraping. During the rotary propulsion process, the scraper can more effectively scrape off the stubborn impurities attached to the filter screen due to its movement direction and the pressure applied, especially for some impurities with high viscosity or particles that are closely adsorbed to each other.

In facilities such as sewage treatment plants, sewage is generated continuously, which ensures the automation effect of the device.

[0035] See also Figure 1-8 The first filter cartridge 301 and the second filter cartridge 302 are both provided with a fixing frame 205 , and the fixing frame 205 of the first filter cartridge 301 and the fixing frame 205 of the second filter cartridge 302 are connected by a connecting rod to achieve a stable installation of the device.

[0036] See also Figure 1-8 The body of the first filter cartridge 301 is provided with a first structural ring 3001, the inner ring of the first structural ring 3001 is provided with a connecting channel ring 3002, the interior of the second filter cartridge 302 is provided with a second structural ring 3021, the inner ring of the second structural ring 3021 is provided with a threaded ring 30211, when the second cleaning component 3003 is cleaning, a second servo motor 30221 is provided, and the connection mode between the second servo motor 30221 and the first rotating rod 3022 can be optionally coupled. When the first rotating rod 3022 rotates, the first rotating rod 3022 will cause the threaded shaft 3023 to rotate under the action of the limiting convex 30241. At this time, under the action of the threads of the threaded shaft 3023 and the threaded ring 30211, the threaded shaft 3023 will eventually rotate and retract, thereby realizing the spiral propulsion movement of the second scraper 3027.

[0037] See also Figure 1-8 One end of the first filter screen 4 is fixedly connected to one side of the inner wall of the first filter cylinder 301, the other end of the first filter screen 4 is fixedly connected to one side of the first structural ring 3001, and both ends of the second filter screen 5 are respectively connected to the opposite sides of the first structural ring 3001 and the second structural ring 3021.

A first servo motor 3016 is provided on the top of the first filter cartridge 301 through a connecting piece. The rotating shaft of the gear 3015 is connected to the rotating shaft of the first servo motor 3016. When cleaning, the cleaning water is introduced from the second three-way pipe 101. At this time, the second water inlet valve 202 and the second water outlet valve 204 of the main filter mechanism 2 or the auxiliary filter mechanism 3 that do not need to be cleaned are closed, so the cleaning water will enter the second filter cartridge 302 from the second water inlet valve 202, and enter from the outer circle of the second filter screen 5, and flow through the inner circle of the first filter screen 4, and finally flow out from the second water outlet valve 204.

[0039] See also Figure 1-8 The second cleaning component 3003 includes a threaded shaft 3023, which is threadedly connected to the threaded ring 30211, and one side of the threaded ring 30211 is rotatably provided with a first rotating rod 3022, and one end of the threaded shaft 3023 is fixedly connected to a limiting rod 3024 movably inserted into the inner ring of the first rotating rod 3022, and the side of the rod body of the limiting rod 3024 is fixedly connected to the limiting protrusion 30241. By setting the second cleaning component 3003, the second scraper 3027 can perform rotational propulsion scraping. During the rotational propulsion process, the scraper can more effectively scrape off stubborn impurities attached to the filter screen due to its movement direction and the pressure applied, especially for some impurities with high viscosity or particles that are closely adsorbed to each other.

[0040] See also Figure 1-8 A long through groove 30222 matched with the limiting protrusion 30241 is opened on the rod body of the first rotating rod 3022, and a second servo motor 30221 is provided at the bottom of the second filter cylinder 302 through a structural member, and the output shaft of the second servo motor 30221 is connected to the end of the first rotating rod 3022.

[0043] See also Figure 1-8 The two ends of the first three-way pipe 1 are connected with the first water inlet valve 201 of the main filtering mechanism 2 and the auxiliary filtering mechanism 3, and the two ends of the second three-way pipe 101 are connected with the second water inlet valve 202 of the main filtering mechanism 2 and the auxiliary filtering mechanism 3. By setting the second filter screen 5 and combining with the first filter screen 4, the two are vertically arranged. When filtering, the sewage will first flow through the lower part of the first filter screen 4 and the second filter screen 5. After the relatively lower part of the filter screen is blocked to a certain extent by stains, the liquid level of the water that has not flowed out will rise, and continue to filter from the part of the filter screen that has not played the filtering function before, so that before all-round cleaning is required, compared with the all-round contact between the filter screen and the sewage, there is always a part of the unused filter screen on standby, which ensures the water flow.

[0044] Specifically, the working process or working principle of this industrial automated sewage filtering device is as follows: when in use, the main filtering mechanism 2 is generally used for filtering. At this time, the second water inlet valve 202 and the second water outlet valve 204 of the main filtering mechanism 2 are closed, and the industrial sewage enters the main filtering mechanism 2 from the first water inlet valve 201 for filtering. After a certain period of use, when the internal filter screen needs to be cleaned, the first water inlet valve 201 and the first water outlet valve 203 of the auxiliary filtering mechanism 3 are opened, and the first water inlet valve 201 and the first water outlet valve 203 of the main filtering mechanism 2 are closed at the same time, and the auxiliary filtering mechanism 3 is used to perform automatic filtering operations, and the filter screen of the main filtering mechanism 2 is cleaned at the same time to achieve non-stop cleaning. When cleaning, the cleaning water is introduced from the second three-way pipe 101. At this time, the second water inlet valve 202 and the second water outlet valve 204 of the main filtering mechanism 2 or the auxiliary filtering mechanism 3 that do not need to be cleaned are closed, so the cleaning The washing water will enter the second filter cartridge 302 from the second water inlet valve 202, and enter from the outer ring of the second filter screen 5, flow through the inner ring of the first filter screen 4, and finally flow out from the second water outlet valve 204. When the first cleaning component 3011 is working, the first servo motor 3016 rotates to drive the first gear 3015 to rotate, so that the slotted ring 3012 drives the first scraper 3014 to scrape off impurities. When the second cleaning component 3003 is cleaning, a second servo motor 30221 is set. The connection method between the second servo motor 30221 and the first rotating rod 3022 can be optionally coupled. When the first rotating rod 3022 rotates, the first rotating rod 3022 will cause the threaded shaft 3023 to rotate under the action of the limiting convex 30241. At this time, under the action of the threads of the threaded shaft 3023 and the threaded ring 30211, the threaded shaft 3023 will eventually rotate and retract, thereby realizing the spiral propulsion and sweeping of the second scraper 3027.
