DETAILED DESCRIPTION

[0051] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0052] Please refer to Figures 1 to 11 , the present application provides a technical solution:

[0053] A membrane filter water treatment equipment, comprising a fixed base frame 1, the fixed base frame 1 is welded by high strength hollow steel pipe, and moreover, the through hole is provided at the left and right front and rear four corner positions of the fixed base frame 1, the inside of the through hole is used for installing threaded rod or other used to fix the fixed base frame 1, prevent the fixed base frame 1 from moving or shaking during the operation process, such as Figure 2 as shown.

[0054] The second fixed rod 102 is fixedly installed at the upper left end center position of the fixed base frame 1, the top of the second fixed rod 102 is provided with a conveying assembly 2, wherein the first protective shell 201 of the conveying assembly 2 and the top of the second fixed rod 102 are fixedly connected, as Figure 2 as shown, wherein the inside of the first protective shell 201 is a cavity structure, and the right end face is in an open state.

[0055] The water conveying pipe 202 in vertical state is fixedly installed on the outer circumferential surface of the first protective shell 201 close to the left end, the upper end face to the lower end face of the water conveying pipe 202 is in a through state, and the inside of the water conveying pipe 202 and the first protective shell 201 is in a through state, so that when the top of the water conveying pipe 202 is connected with the water pipe outside, the water source can enter the inside of the first protective shell 201 through the water conveying pipe 202, as Figure 3 as shown.

[0056] Second, the left end face of the first protective shell 201 is fixedly installed with a telescopic pump 203 (it is necessary to explain that the telescopic pump 203 is used for hydraulic oil operation or gas driving operation, which needs to be designed according to the actual situation), and then the left end of the first protective shell 201 is slidably installed with a sealing rod 204, the left end of the sealing rod 204 is fixedly connected with the telescopic rod of the telescopic pump 203, the telescopic rod of the telescopic pump 203 penetrates through the first protective shell 201, and then the sealing rod 204 can perform linear reciprocating motion in the first protective shell 201, and in the process of movement, the sealing rod 204 can seal the position connected through the first protective shell 201 and the water pipe 202, so that the water source in the water pipe 202 cannot enter the inside of the first protective shell 201, as shown in Figure 3

[0057] Second, the right end of the sealing rod 204 is fixedly installed with a water feeding cylinder 205, the right end face to the inside of the water feeding cylinder 205 is in a through state, and the circumferential surface of the water feeding cylinder 205 is provided with a through hole near the left end, the through hole is in communication with the lower end of the water pipe 202, as shown in Figure 3

[0058] In use, the top of the water pipe 202 is rotatably connected with the water pipe outside, so that the water source outside which needs to be purified enters the inside of the first protective shell 201 through the water pipe 202, at this time, since the through hole on the circumferential surface of the water feeding cylinder 205 is in the same straight line with the lower end opening of the water pipe 202, therefore, the sewage will enter the inside of the water feeding cylinder 205.

[0059] At this time, the telescopic pump 203 is started, the telescopic rod of the telescopic pump 203 will slide horizontally with the sealing rod 204 in the inside of the first protective shell 201 to the right, and in the process of sliding of the sealing rod 204, the water feeding cylinder 205 will be synchronously slid in the inside of the first protective shell 201, at this time, the sealing rod 204 seals the lower end opening of the water pipe 202, and the water in the water feeding cylinder 205 is transported to the inside of the next operation process, at this time, since the position of the water feeding cylinder 205 moves, the volume of the subsequent internal operation changes, at this time, a pressure is generated on the water source of the subsequent operation, and then the pressure is transmitted to the inside of the membrane filtration assembly 5, so as to form a pushing force on the water source in the inside of the third protective shell 501 of the membrane filtration assembly 5, so that the water source can be continuously filtered.

[0060] ​​When the water delivery tank column 205 is reset under the driving of the sealing rod 204, the pressure disappears, and the water source in the water delivery pipe 202 enters the inside of the water delivery tank column 205 again, and then repeats the above steps under the action of the telescopic pump 203, so that the water source can be pressurized again, thereby ensuring the filtration operation of the water source.

[0061] Under the cooperation of the above structures, an additional pressure can be generated on the water source being filtered, thereby accelerating the sewage filtration speed under the action of the pressure, keeping the water source inside the structure in an uninterrupted state, so that the bacteria in the first protective shell 201 of the membrane filtration assembly 5 cannot be adsorbed on the surface of the filter membrane 508 for a long time, thereby prolonging the service life of the filter membrane 508 and improving the filtration efficiency.

[0062] In addition, the gel assembly 3 is fixedly installed at the right end of the first protective shell 201 by using flanges, screws and nuts, and the filter box 301 in the gel assembly 3 is fixedly connected to the right end of the first protective shell 201 by using flanges, screws and nuts, as shown in Figure 1 .

[0063] The first fixing rod 101 is fixedly installed at the lower end of the filter box 301, and the lower end of the first fixing rod 101 is fixedly installed on the upper end surface of the fixed base frame 1, as shown in Figure 1 . Then, two longitudinal through holes 302 are formed in the upper end surface of the filter box 301, and the through holes 302 and the inside of the filter box 301 are in communication, as shown in Figure 5 .

[0064] Then, the activated carbon plate 303 is slidingly installed in the through hole 302, the lower end of the activated carbon plate 303 slides into the inside of the filter box 301, and the inside bottom surface of the filter box 301 is in close contact with the activated carbon plate 303, and then the electrode rod 304 is fixedly installed between the left and right activated carbon plates 303, and the top of the electrode rod 304 extends to the outside of the filter box 301, as shown in Figure 4 .

[0065] The device is used for treating sewage, and a large amount of impurities are contained in the sewage, and the most difficult to treat is the gel. Therefore, the activated carbon plate 303 is used to block the gel in the sewage to avoid affecting the subsequent membrane filtration. Because the surface of the activated carbon plate 303 is provided with an adsorption device, the gel can be adsorbed firmly during use, so that the gel cannot flow with the sewage, thereby ensuring the subsequent operation effect and avoiding affecting the filtration effect of the filter membrane 508.

[0066] Secondly, under the action of the electrode rod 304, the inside of the filter box 301 can generate an electric field, so that the colloidal in the filter box 301 can be coagulated. Under the action of the electric field, the colloidal particles move to the electrode direction and collide and coagulate, and finally form large particle precipitates, so as to ensure the filtration of the activated carbon plate 303, so that the activated carbon plate 303 will not be blocked, and the use time of the activated carbon plate 303 can be increased. In the process of use, the activated carbon plate 303 can be replaced in real time under the action of the through hole 302, so as to ensure the blocking operation of the colloidal.

[0067] In addition, the filter assembly 4 is arranged at the right end of the filter box 301, the second protective shell 401 in the filter assembly 4 is fixedly connected with the right end of the filter box 301 by using the flange, screw rod and nut, as shown in Figure 1 The inner left and right circumferential surfaces of the second protective shell 401 are provided with internal threads 402, and then the connecting pipe 403 is slidingly installed in the inside of the second protective shell 401. The left end to the right end of the connecting pipe 403 is in a through state, and a plurality of filter plates 405 are fixedly installed in the inside of the connecting pipe 403 in a transverse and uniform manner, for secondary filtering operation of impurities in sewage, as shown in Figure 7 .

[0068] Then, the hollow threaded column 404 is fixedly installed at the left and right ends of the connecting pipe 403. The outer side surface of the hollow threaded column 404 is provided with external threads. The hollow threaded column 404 and the inside of the second protective shell 401 are rotatably connected under the action of the external threads, and then the connecting pipe 403 is rotatably installed in the inside of the second protective shell 401, as shown in Figure 6 .

[0069] In the process of use, after the sewage in the inside of the filter box 301 enters the inside of the second protective shell 401, it will pass through the filter plates 405 with different hole diameters layer by layer. Under the action of the filter plates 405, the impurities in the sewage can be secondary filtered, so as to further improve the filtering effect.

[0070] Under the action of the flange, screw rod and nut, the second protective shell 401 can be disassembled in real time. After disassembly is completed, the connecting pipe 403 in the inside can be taken out by rotating one of the hollow threaded columns 404. In this way, the new connecting pipe 403 can be replaced, and then the new filter plate 405 is replaced. Therefore, the filtering effect and efficiency can be ensured, and the filtering efficiency and speed are not affected after the filter plate 405 is blocked, so as to cause unnecessary blockage and reduce the flow of water flow.

[0071] And in the second protective shell 401 right end flange, screw and nut fixed installation has membrane filter assembly 5 in the third protective shell 501, wherein the third protective shell 501 left end face to right end face is through state, and, in the inside right end of third protective shell 501 rotatable mounting has water outlet pipe 502, as Figure 1 Indicated.

[0072] Then, in the third protective shell 501 inside right end close to the left end of water outlet pipe 502 rotatable mounting has rotating plate 504 (the inside right end of third protective shell 501 is provided with screw thread), rotating plate 504 center position fixed mounting has hollow tube 505, hollow tube 505 right end face to the inside is through state, second is, between the adjacent two rotating plate 504 slidingly mounted sealing slide block 514, sealing slide block 514 can be right end of filter membrane 508 plugging operation, when the subsequent extraction of filter membrane 508 will not let the rest of the filter membrane 508 stop operation, ensure the continuity of operation.

[0073] It should be noted that, in the process of operation, the left side of water outlet pipe 502 and the right side of rotating plate 504 are in close contact state, thereby ensuring that the sewage will not appear without filtering discharge.

[0074] And then, on the circumferential surface of hollow tube 505 annular array transverse uniform opening has water inlet hole 506, and between the transverse adjacent water inlet hole 506 fixedly installed with partition plate 507, partition plate 507 outer side one end and the inner wall of third protective shell 501 are in close contact state.

[0075] Secondly, between the adjacent each class 507 slidingly mounted with filter membrane 508, filter membrane 508 shell adopts RO membrane as filter material (because, RO membrane is a kind of semi-permeable membrane, its aperture is very small, only 0.0001 microns, equivalent to the diameter of one millionth of hair; this extremely small aperture makes RO membrane can effectively filter the dissolved material, suspended material, bacteria, viruses and other small particles in water, and only allows water molecules and part of mineral ions to pass through), therefore, the filter membrane 508 has super high filtration effect.

[0076] In addition, a ring groove 503 is formed on the inner left end circumferential surface of the third protective shell 501, a gear ring 509 is rotatably installed in the ring groove 503, a sealing shell 513 is fixedly installed on the outer left end circumferential surface of the third protective shell 501, a stepping motor 511 is fixedly installed on the outside of the third protective shell 501 and inside the sealing shell 513, a gear 512 is fixedly installed on the output shaft of the stepping motor 511, the gear 512 meshes with the tooth groove on the outer circumferential surface of the gear ring 509 inside the third protective shell 501 and the ring groove 503, and a sealing plate 510 in a generally trapezoidal structure is fixedly installed on the inner circumferential surface of the gear ring 509. The size of the sealing plate 510 is consistent with the size between the two partitions 507, so that the sealing plate 510 can seal the filter membrane 508 with poor filtering effect during use, and then the operator can replace the filter membrane 508 without affecting the operation of other filter membranes 508.

[0077] Therefore, during use, the stepping motor 511 is started, the output shaft of the stepping motor 511 drives the gear 512 to rotate, the gear 512 drives the gear ring 509 to rotate synchronously, the gear ring 509 drives the sealing plate 510 to rotate synchronously (it should be noted that a waterproof miniature camera is fixedly installed on the inner left end of the third protective shell 501 to observe the rotation of the sealing plate 510, so that the sealing plate 510 can seal the left end of the adjacent partition), then the water outlet pipe 502 is rotated and removed, and the filter membrane 508 with reduced filtering effect can be extracted.

[0078] Secondly, the filtered water source passes through the water inlet hole 506 into the inside of the hollow pipe 505, then flows to the right end opening, and finally enters the water outlet pipe 502 and flows out.

[0079] In addition, the sealing shell 513 on the outer circumferential surface of the third protective shell 501 is used to protect the stepping motor 511 and avoid the pressure inside the third protective shell 501 from decreasing. It should be noted that during use, air pressure can be injected into the inside of the third protective shell 501 to further improve the filtering effect. The air pressure compresses the water source so that the water source can be continuously filtered by the filter membrane 508.

[0080] Finally, the servo motor 103 is fixedly installed at the right part of the upper end of the fixed base frame 1, a rotating disc 104 is fixedly installed on the output shaft of the servo motor 103, and four clamping grooves 105 are formed in the rotating disc 104, wherein the third protective shell 501 is slidingly installed in the clamping groove 105, and it is to be noted that the third protective shell 501 can be fixed by using a fixing block or a fixing device when the third protective shell 501 is slidingly installed in the clamping groove 105, and the filter membranes 508 in the four third protective shells 501 are made of different materials, so that the filter membranes 508 can be suitable for different polluted water sources, and the practicability of the device is greatly improved.

[0081] Working principle: first, the water pipe 202 is connected with the external pipeline, so that the water source passes through the water pipe 202 and enters the inside of the first protective shell 201.

[0082] The telescopic pump 203 is started, the telescopic rod of the telescopic pump 203 moves with the sealing rod 204, the sealing rod 204 seals the lower end of the water pipe 202, and the water delivery cylinder 205 moves synchronously, the water delivery cylinder 205 moves the water and generates a certain amount of pressure, so that the water source in the third protective shell 501 is in an uninterrupted movement state.

[0083] Then, the water source enters the inside of the filter box 301, and under the action of the activated carbon plate 303 and the electrode rod 304, the colloidal particles can be blocked and gathered together.

[0084] Then the water source enters the inside of the filter second protective shell 401, and under the action of the filter plate 405 in the connecting pipe 403, the water source is subjected to secondary filtering operation, and the filtered water source enters the inside of the third protective shell 501.

[0085] At this time, the water source will continuously pass through the filter membrane 508, then pass through the water inlet hole 506 and enter the inside of the hollow pipe 505, then flow out from the right end of the hollow pipe 505, and finally flow out through the water outlet pipe 502.

[0086] Finally, when the new filter membrane 508 is replaced, the water outlet pipe 502 is rotated and removed, and the filter membrane 508 is extracted, and when the filter membrane 508 is extracted, the stepping motor 511 is driven, the output shaft of the stepping motor 511 rotates with the gear 512, the gear 512 drives the gear ring 509 to rotate, and the gear ring 509 seals the left side of the filter membrane 508 to be extracted with the sealing plate 510, so that the water flow is prevented.

[0087] After completion, the sealing plate 510 moves to the center position of one of the partitions 507 to make the two filter membranes 508 work synchronously.

[0088] It should be pointed out finally that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the same; although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions recorded in the above embodiments can still be modified, or some or all of the technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
