Description

Technical Field

[0001] The invention relates to the technical field of air separation oxygen production, and in particular to a water filtering device for air separation oxygen production. Background Art

[0002] Water used in air separation oxygen production plays a key role in the oxygen production process. The oxygen generator liquefies the air through compression, expansion and cooling, and separates oxygen and nitrogen by using the difference in gasification temperature. In this process, water is used as a coolant to ensure that the air can be cooled to a low enough temperature to achieve liquefaction. Generally, the water used needs to have high purity and good thermal stability, such as distilled water or purified water, to prevent corrosion to the equipment and ensure oxygen production efficiency. These water quality characteristics help to ensure the long-term stable operation of the air separation oxygen generator and the purity of oxygen.

The utility model uses a cleaning mechanism assembly, and when the device is in use, the device can effectively remove impurities adhered to the filter holes of the filter screen, thereby ensuring the dredging effect of the filter screen on the water flow, and at the same time, it can ensure the smoothness of the sewage outlet of the fixed plate, and avoid dirt from clogging the sewage outlet of the fixed plate. Through the water flow regulating mechanism assembly, the user can freely control the flow rate of the water flow inside the device to reduce the impact of the water flow on the filter screen; however, the above patent document still has the following defects during implementation:

[0004] Although the above patent can clean the filtered impurities during implementation, it is unable to separate and remove the grease in the water, resulting in damage to the molecular sieve in the oxygen generator. At the same time, the volatilization and decomposition products of the grease may be mixed into the produced oxygen, resulting in a decrease in the purity of the oxygen. In addition, the grease may also react chemically with other gas components to generate harmful by-products, further affecting the quality of the oxygen. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1, as Figure 1 and Figure 2 As shown, a water filtering device for air separation oxygen production includes a device shell 1, support legs 2 are fixedly connected to the four corners of the lower end of the device shell 1, a cabinet door 3 is rotatably connected to the front end of the device shell 1, a water inlet pipe 4 is fixedly connected to the right part of the upper end of the device shell 1, and a water outlet pipe 5 is fixedly connected to the left part of the lower front end of the device shell 1. The inner surface and left and right ends of the device shell 1 are jointly provided with an oil removal component 6, and a filter component 7 is provided on the inner surface of the device shell 1 below the oil removal component 6.

[0035] During the implementation of this embodiment, a certain amount of water is injected into the inner cavity of the device shell 1 through the water inlet pipe 4. At this time, the water is first subjected to a preliminary degreasing operation by flotation through the degreasing component 6, and then the grease in the water is adsorbed by adsorption, and other polluting organic matter in the water can be separated and removed. Finally, a chemical coagulation method is used to add a coagulant such as polyaluminum chloride, iron salt, etc. to the water, so that the grease and other suspended matter in the water form flocs and precipitate to perform degreasing operation. The degreasing water passes through the filter component 7 to remove particulate matter in the water, and is discharged from the device shell 1 through the water outlet pipe 5 to enter the relevant distillation equipment for distillation operation, and finally pure water for oxygen production is obtained.

[0036] Specifically, in order to remove oil from water, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 In this embodiment, the oil removal component 6 includes a rectangular hole frame 61 fixedly installed on the right end of the device housing 1, a rectangular frame 62 fixedly installed on the left end of the device housing 1, a collecting frame 63 movably installed on the left end of the rectangular frame 62, a circular hole partition 64 fixedly connected to the inner surface of the device housing 1, a blower mechanism 65 is arranged at the lower end of the circular hole partition 64, an oil scraping mechanism 66 is arranged above the circular hole partition 64 on the inner surface of the device housing 1, an adsorption mechanism 67 is arranged at the lower end of the circular hole partition 64, a separation mechanism 68 is arranged below the blower mechanism 65 on the inner surface of the device housing 1, and a cleaning mechanism 69 is arranged on the left part of the inner surface of the rectangular frame 62.

[0037] For further information, see Figure 4 and Figure 5 In this embodiment, the air blowing mechanism 65 includes an air outlet pipe 651 fixedly connected to the lower part of the inner surface of the circular hole partition 64, the right end of the air outlet pipe 651 is fixedly connected to an air pump 652 fixedly connected to the right end of the device housing 1, a plurality of waterproof and breathable membranes 653 are fixedly connected to the inner surface of the air outlet pipe 651, an L-shaped plate 654 fixedly connected to the inner surface of the rectangular frame 62 is fixedly connected to the left part of the upper end of the circular hole partition 64, and an oil drain pipe 655 is fixedly connected to the inner surface of the L-shaped plate 654.

[0038] During the implementation process, after a certain amount of water is injected from the water inlet pipe 4, the water will be retained in the space formed by the L-shaped plate 654, the circular hole partition plate 64 and the device housing 1, and the air pump 652 is started to draw air into the air outlet pipe 651. Under the action of the waterproof breathable membrane 653, air can be injected into the water, generating tiny bubbles in the water. When the bubbles rise, they adhere to the oil droplets in the water and bring them out of the water surface, thereby achieving the preliminary separation of grease.

[0039] The waterproof breathable membrane 653 mentioned above is a mature technical membrane in the prior art. In this solution, its function of blocking the flow of water without affecting the flow of air is utilized, and its structure and principle are not further elaborated.

[0040] For further information, see Figure 4 , Figure 6 and Figure 7 In this embodiment, the oil scraping mechanism 66 includes a fixing plate 6611 fixedly connected to the front and rear of the inner surface of the device housing 1, a dual-axis motor 662 is fixedly installed on the right end of the device housing 1, and the right end output end of the dual-axis motor 662 is fixedly connected to a rotating rod 665 through a coupling. The right end of the device housing 1 penetrates and extends to the left end of the fixing plate 6611 and is rotatably connected to a reciprocating rod 663. The outer surface of the rotating rod 665 is fixedly connected to a one-way bearing 664, and the outer surface of the one-way bearing 664 and the right part of the outer surface of the reciprocating rod 663 are fixed together. A pulley set 666 is connected, and guide grooves 661 are symmetrically provided on the front upper side and the rear upper side of the inner surface of the device housing 1. A slider 667 is slidably connected to the outer surface of the reciprocating rod 663, and a round rod scraper 668 is slidably connected to the inner surface of the slider 667. The upper end of the round rod scraper 668 is fixedly connected to a guide rod 669 slidably connected to the inner surface of the guide groove 661. Two springs 6610 are sleeved on the outer surface of the round rod scraper 668, and the two ends of the two springs 6610 are respectively fixedly connected to the upper end of the slider 667 and the outer surface of the guide rod 669.

[0041] During the implementation process, under the action of the blower mechanism 65, the grease in the water will float on the water surface. At this time, the right end output end of the dual-axis motor 662 is started to drive the rotating rod 665 to rotate through the coupling. At this time, under the cooperation of the one-way bearing 664 and the pulley group 666, the reciprocating rod 663 is driven to rotate. Since the reciprocating rod 663 and the slider 667 are slidably connected, the reciprocating rod 663 drives the slider 667 to reciprocate left and right during the rotation process, and at the same time drives the guide rod 669 to slide on the inner surface of the guide groove 661, so that the round rod scraper 668 moves to the left. The oil on the water surface is scraped away dynamically and retained on the round rod scraper 668. When the guide rod 669 moves to the leftmost side of the guide groove 661, the inner surface of the guide groove 661 becomes higher, so that the guide rod 669 moves upward under the compression reaction of the spring 1 6610, and the position of the round rod scraper 668 is lifted to pass above the L-shaped plate 654. Since the scraping surface of the round rod scraper 668 is an inclined surface, the scraped grease will fall on the L-shaped plate 654 under the action of gravity, and be discharged into the collection frame 63 through the oil drain pipe 655, thereby effectively realizing the preliminary separation of grease and water and reducing the pressure of subsequent processes.

[0042] The pulley assembly 666 mentioned above is composed of two pulleys and a belt.

[0043] The water level mentioned above is at the same level as the height of the upper end of the L-shaped plate 654.

[0044] The reciprocating rod 663 and the slider 667 mentioned above constitute a ball screw mechanism with mature prior art.

[0045] For further information, see Figure 4 and Figure 8 In this embodiment, the adsorption mechanism 67 includes a connecting pipe 671 that passes through the front part of the upper end of the circular hole partition 64 and extends to the lower end of the circular hole partition 64 and is fixedly connected. A solenoid valve 672 is fixedly installed on the inner surface of the connecting pipe 671. An adsorption tank 673 is fixedly installed on the right end of the connecting pipe 671. A connecting pipe 2 674 is fixedly installed on the right end of the adsorption tank 673. A plurality of blocking blocks 675 are fixedly connected to the inner surface of the connecting pipe 671 in a linearly staggered manner.

[0046] During the implementation process, the solenoid valve 672 is started so that the initially separated water will enter the connecting pipe 671 under the action of gravity, and the flow rate of the water will be reduced under the action of the blocking block 675, so that the water can slow down the flow rate and enter the adsorption tank 673. The oil pollutants are adsorbed and removed by the activated carbon, polymer adsorbent and other materials in the adsorption tank 673. The adsorbent has a large specific surface area and good adsorption performance, and can effectively remove oil and other organic pollutants in the water.

[0047] The adsorption tank 673 mentioned above is a mature adsorption technology means in the prior art. In this solution, it can be used to store materials such as activated carbon and polymer adsorbents, and can be replaced.

[0048] For further information, see Figure 4 and Figure 8 In this embodiment, the separation mechanism 68 includes a circular groove block 681 fixedly connected to the inner surface of the device housing 1, the right end of the device housing 1 extends through and extends to the left end of the device housing 1 and is rotatably connected to a threaded rod 682 fixedly connected to the left end output end of the dual-axis motor 662, the outer surface of the threaded rod 682 is threadedly connected to a filter screen plate 684 slidably connected to the inner surface of the circular groove block 681, the middle side of the lower part of the inner surface of the circular groove block 681 penetrates and extends to the lower end of the circular groove block 681 and is fixedly connected to a connecting pipe three 685, the inner surface of the connecting pipe three 685 is fixedly installed with an electromagnetic valve two 686, and the inner surface of the circular groove block 681 is connected to the inner surface of the connecting pipe two 674.

[0049] During the implementation process, the adsorbed water will enter the circular groove block 681 under the action of gravity. At this time, the user can put coagulants such as polyaluminum chloride, iron salts, etc. into the circular groove block 681 for static, so that the oil droplets and other suspended matter in the water form flocs and settle down. Then, by starting the left end output end of the dual-axis motor 662, the threaded rod 682 is driven to rotate through the coupling. Since the threaded rod 682 is threadedly connected to the filter screen plate 684, the threaded rod 682 drives the filter screen plate 684 to move to the left during the rotation. The filter screen plate 684 can filter the oil droplets and other suspended matter in the water to form flocs and collect them at the left end of the filter screen plate 684, and collect all the flocs in the inner cavity of the circular groove block 681 during the movement, thereby realizing the operation of separating the oil in the water again, which can improve the purity of the water and facilitate the subsequent oxygen production operation.

[0050] For further information, see Figure 4 , Fig. 9 and Fig.10 In this embodiment, the cleaning mechanism 69 includes a fixing ring 691 fixedly connected to the left portion of the inner surface of the rectangular frame 62, a fixing plate 692 is fixedly connected to the left portion of the inner surface of the rectangular frame 62 above the fixing ring 691, a round rod block 693 is rotatably connected to the inner surface of the fixing ring 691, a transmission rod 694 is rotatably connected to the lower end of the fixing plate 692 at the right side of the upper front end of the fixing plate 692, a transmission rod 694 is rotatably connected to the lower end of the fixing plate 692, a transmission rod 699 is rotatably connected to the rear end of the fixing plate 692 at the right front end of the fixing plate 692, a cleaning brush 696 is slidably connected to the inner surface of the round rod block 693, and two springs 697 are sleeved on the outer surface of the cleaning brush 696, and the two ends of the two springs 697 are respectively fixedly connected to the right end of the round rod block 693 and the left end of the cleaning brush 696, A rack 698 is fixedly connected to the lower middle part of the rear end of the filter plate 684, a transmission gear 6910 meshing with the rack 698 is fixedly connected to the rear end of the transmission rod 2 699, a transmission mechanism 1 695 is fixedly connected to the upper end of the transmission rod 1 694 and the front end of the transmission rod 2 699, a transmission mechanism 2 6911 is fixedly connected to the left end of the round rod block 693 and the lower end of the transmission rod 1 694, a plurality of steel balls 6912 are arranged in a ring on the inner surface of the cleaning brush 696, the size and shape of the outer surface of the cleaning brush 696 are matched with the size and shape of the inner surface of the circular groove block 681, when the cleaning brush 696 is separated from the circular groove block 681, the spring 2 697 is compressed by the cleaning brush 696, and at this time the rack 698 meshes with the transmission gear 6910 and drives the transmission gear 6910 to rotate.

[0051] As can be seen from the above, in the process of the filter screen plate 684 continuously moving to the left, the circular protrusion on the filter screen plate 684 will be inserted into the inner surface of the cleaning brush 696, and will push the cleaning brush 696 to move to the left. At this time, the solenoid valve 2 686 is opened, so that the degreased water flows away through the connecting pipe 3 685 under the action of gravity. In the process of the cleaning brush 696 leaving the inner surface of the circular groove block 681, the cleaning brush 696 will squeeze the spring 2 697 in a compressed state, and at the same time, the rack 698 is meshed with the transmission gear 6910. The continuous movement of the rack 698 to the left will drive the transmission gear 6910 to rotate, and under the cooperation of the transmission rod 1 694, the transmission mechanism 1 695, the transmission rod 2 699 and the transmission mechanism 2 6911, it drives the round rod block 693 to rotate, and then drives the cleaning brush 696 to rotate to clean the flocs filtered by the filter screen plate 684, and fall into the collection frame 63 under the action of gravity.

[0052] Secondly, after the flocs are cleaned, the left output end of the dual-axis motor 662 drives the threaded rod 682 to rotate in the opposite direction, driving the filter plate 684 to move to the right. The circular protrusion on the filter plate 684 will gradually move away from the cleaning brush 696, allowing the cleaning brush 696 to reset under the compression reaction of the spring 2 697 and re-enter the inner surface of the circular groove block 681.

[0053] The size and shape of the outer surface of the cleaning brush 696 mentioned above are compatible with the size and shape of the inner surface of the circular groove block 681, and at the same time, the water level inside the circular groove block 681 after water injection cannot push the cleaning brush 696 out of the inner surface of the circular groove block 681.

[0054] The transmission mechanism 1 695 and the transmission mechanism 2 6911 mentioned above are both composed of two bevel gears.

[0055] The solenoid valve 1 672 and the solenoid valve 2 686 mentioned above are both mature control technology means and equipment in the prior art. In this solution, their function of controlling the flow direction of the fluid is utilized, and their structure and principle are not further elaborated.

[0056] Embodiment 2: Based on Embodiment 1, this embodiment adds a filter assembly 7 for filtering the water after oil removal, so as to achieve the purpose of filtering the water after oil removal.

[0057] Specifically, in order to filter the deoiled water, refer to Figure 4 , Figure 8 , Fig.11 and Fig.12 In this embodiment, the filter assembly 7 includes a W-shaped filter screen 71 fixedly connected to the inner surface of the device housing 1, a cleaning mechanism 72 is provided on the inner surface of the device housing 1 above the W-shaped filter screen 71, and a sealing mechanism 73 is provided on the left part of the inner surface of the rectangular frame 62.

[0058] For further information, see Figure 4 , Figure 8 and Fig.11 In this embodiment, the cleaning mechanism 72 includes a slide groove 721 opened at the front part of the lower end of the circular groove block 681, and a slider 2 722 is slidably connected to the inner surface of the slide groove 721. A reciprocating rod 2 725 slidably connected to the slider 2 722 is rotatably connected to the lower right end of the device housing 1 and extends to the left end of the device housing 1. A one-way bearing 2 723 is fixedly connected to the outer surface of the rotating rod 665. A pulley group 2 724 is fixedly connected to the outer surface of the one-way bearing 2 723 and the right part of the outer surface of the reciprocating rod 2 725. A cleaning plate 726 is fixedly connected to the lower end of the slider 2 722.

[0059] During the implementation process, the deoiled water will fall onto the W-shaped filter 71 through the connecting pipe three 685 under the action of gravity. Since the W-shaped filter 71 has an arc surface, the falling water can be separated and fall into the two concave spaces of the W-shaped filter 71. The particles in the water will be filtered and fall into the two concave corner spaces, and then the water can be filtered to remove the particulate impurities.

[0060] Secondly, start the left output end of the dual-axis motor 662 to drive the rotating rod 665 to rotate in the opposite direction. Under the cooperation of the one-way bearing 723 and the pulley group 724, the reciprocating rod 725 is driven to rotate so that the slider 722 slides on the inner surface of the slide groove 721, and drives the cleaning plate 726 to slide on the inner surface of the W-shaped filter 71 to clean the filtered particulate impurities.

[0061] The pulley group 2 724 mentioned above is composed of two pulleys and a belt.

[0062] The one-way bearing 1 664 and the one-way bearing 2 723 mentioned above are mature one-way rotating parts in the prior art. This scheme utilizes their function of being able to rotate freely in one direction and being locked in the other direction. In this scheme, the locking directions of the one-way bearing 1 664 and the one-way bearing 2 723 are opposite, and their structure and principle are not further elaborated.

[0063] The reciprocating rod 2 725 and the sliding block 2 722 mentioned above constitute a mature ball screw mechanism in the prior art.

[0064] The dual-axis motor 662 mentioned above is a mature driving technology device in the prior art, and is a mature driving technology means in the prior art. This solution utilizes it to rotate independently on both sides, and the number of positive and negative rotations on both sides can be adjusted and controlled separately, and it can stop in time after rotating to the set number of circles.

[0065] The cleaning plate 726 is initially located at the rightmost side of the W-shaped filter screen 71 .

[0066] For further information, see Figure 4 and Fig.12 In this embodiment, the blocking mechanism 73 includes a telescopic rod 731 fixedly connected to the left part of the inner surface of the rectangular frame 62, a blocking plate 732 is fixedly connected to the right end of the telescopic rod 731, and a spring three 733 is sleeved on the outer surface of the telescopic rod 731, and the two ends of the spring three 733 are respectively fixedly connected to the inner surface of the rectangular frame 62 and the left end of the blocking plate 732.

[0067] During the implementation process, as the cleaning plate 726 moves to the left, the protrusion on the cleaning plate 726 will push the blocking plate 732 to gradually move to the left, while squeezing the telescopic rod 731 and the spring three 733. At this time, the granular impurities scraped off by the cleaning plate 726 will fall into the collecting frame 63 under the action of gravity, and the debris generated by the three separations can be uniformly collected in the collecting frame 63.

[0068] Working process: When in use, the injected water is floated by the blower mechanism 65, and the grease in the water will float on the water surface, and then the floating grease is scraped off by the scraper mechanism 66 and concentrated in the collection frame 63. The water after preliminary treatment is adsorbed by the adsorption mechanism 67, and then chemically separated again in the separation mechanism 68. During the separation process, the flocs are cleaned by the cleaning mechanism 69, and finally the particles in the water are filtered by the W-shaped filter screen 71. The particulate impurities on the W-shaped filter screen 71 are cleaned with the cooperation of the cleaning mechanism 72 and the blocking mechanism 73.

[0069] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
