DETAILED DESCRIPTION

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1

[0025] In the prior art, in the traditional glass bottle or ceramic bottle packaging industry, there is a problem in the bottle cleaning stage: the wastewater after cleaning will be directly discharged to the outside, causing increased environmental pollution and increasing the cost of water resources required for cleaning.

[0026] Therefore, in order to solve the problem that the existing liquor bottles will directly discharge the washed water to the outside when washing, causing environmental pollution and increasing the washing cost, the washed water can be filtered twice to facilitate recycling. Figure 1 , including a reflux water tank 2 and an outlet pipe 5, the reflux water tank 2 and the outlet pipe 5 can be connected to an external bottle washing machine through a water pipeline, specifically, the frame 1 is provided with a reflux water tank 2 for collecting washing water, a primary filter pipe 3 and a secondary filter pipe 4 for filtering the washing water, and an outlet pipe 5 for discharging the filtered water, wherein the primary filter pipe 3, the secondary filter pipe 4 and the outlet pipe 5 are arranged vertically in the same direction on the top of the reflux water tank 2, the primary filter pipe 3 is connected to the reflux water tank 2 through a pipeline, the primary filter pipe 3, the secondary filter pipe 4 and the outlet pipe 5 are sequentially connected with a clean water pipe 10, and the primary filter pipe 3 and the secondary filter pipe 4 are both provided with a membrane column 19;

[0027] When the sewage from the bottle washing machine enters the reflux water tank 2, the raw water pump 6 can pump the sewage in the reflux water tank 2 into the primary filter tube 3, and then the water production valve 11 will pump the water in the primary filter tube 3 upward, so that the water in the primary filter tube 3 can fully contact with the membrane column 19 in the primary filter tube 3, thereby achieving a filtering effect. Subsequently, the water filtered by the primary filter tube 3 is introduced into the secondary filter tube 4 through the clean water pipe 10, and after being fully mixed with the membrane column 19 in the secondary filter tube 4, it is discharged from the water outlet pipe 5 through the booster pump 12. At this time, the user can use a water pipe to connect the water outlet pipe 5 to the bottle washing machine, so that the purified water can be reused by the bottle washing machine, thereby reducing emissions and saving costs.

[0028] In this embodiment, the membrane column 19 has a hollow cylindrical structure, and the body of the membrane column 19 is provided with a plurality of filter holes which are staggered and stacked, and the pore size thereof is between 0.001 and 0.02 microns. When the sewage in the reflux water tank 2 is pumped into the primary filter tube 3 or the secondary filter tube 4, the sewage will move along the inside of the membrane column 19, and then the impurities in the sewage will be retained inside the membrane column 19, and clean water will flow out from the surface of the membrane column 19 along the filter holes of the membrane column 19.

[0029] In this embodiment, by arranging the primary filter tube 3, the secondary filter tube 4 and the outlet pipe 5 vertically in the same direction on the top of the reflux water tank 2, the structure of the filter unit is made more compact, does not occupy too much site space, and is easy to use and maintain.

[0030] In this embodiment, the membrane column 19 in the first-stage filter tube 3 can be a PVDF ultrafiltration membrane, which adopts a cross-flow filtration method. The membrane column in the second-stage filter tube 4 can be an MBR membrane filtration, which adopts a negative pressure osmosis filtration method. By using two membrane columns 19 made of different materials, the dual filtration effect of sewage is further improved.

[0031] In this embodiment, in order to avoid the backflow of sewage entering the primary filter tube 3, a raw water pump 6 and a check valve 7 are provided at the pipe connection between the reflux water tank 2 and the primary filter tube 3. Through the setting of the check valve 7, the sewage pumped out by the raw water pump 6 will not flow back from the primary filter tube 3. At the same time, the reflux water tank 2 is connected to the interior of the membrane column 19 in the primary filter tube 3 through a pipe.

[0032] In this embodiment, in order to improve the filtering effect on sewage, a return pipe 8 is provided on one side of the primary filter tube 3, and the other end of the return pipe 8 is connected to the return water tank 2. A return valve 9 is provided on the return pipe 8. When in use, one end of the return pipe 8 passes through the primary filter tube 3 and is connected to the membrane column 19 inside it. When the raw water pump 6 draws sewage into the membrane column 19, the filter holes on the body of the membrane column 19 have a small aperture, so the seepage speed of the clean water is slow. At this time, the return valve 9 is opened, so that the return pipe 8 can return the concentrated water that has not been completely filtered to the return water tank 2, so that the water can be pumped into the membrane column 19 by the raw water pump 6 again, so as to prevent blockage in the membrane column 19 and improve the filtering efficiency.

[0033] In this embodiment, a booster pump 12 is provided on the clean water pipe 10 between the secondary filter pipe 4 and the water outlet pipe 5. Through the setting of the booster pump 12, the booster pump 12 can extract the secondary filtered water in the secondary filter pipe 4 and guide it to the water outlet pipe 5.

[0034] In the above embodiment, the booster pump 12 can reversely pressurize and re-pump the clean water in the outlet pipe 5 into the primary filter tube 3 and the secondary filter tube 4 for backwashing. Specifically, the outlet pipe 5 is provided with a backwashing pipe 13 connected to the clean water pipe 10 on the primary filter tube 3. When backwashing is required, the booster pump 12 can pump the clean water into the outlet pipe 5, and then the clean water can enter the primary filter tube 3 through the backwashing pipe 13, and enter the secondary filter tube 4 through the clean water pipe 10, thereby playing a backwashing role.

[0035] In this embodiment, a water production valve 11 is provided on the clean water pipe 10 between the primary filter pipe 3 and the secondary filter pipe 4 , and the water production valve 11 can pump the clean water produced in the primary filter pipe 3 into the secondary filter pipe 4 .

[0036] In the above embodiment, optionally, an ultraviolet lamp is provided inside the water production valve 11 to sterilize the produced purified water by ultraviolet rays.

[0037] In the present embodiment, the primary filter tube 3 and the secondary filter tube 4 are both hollow cylinders, and the membrane column 19 is movably inserted into the primary filter tube 3 and the secondary filter tube 4, wherein the top openings of the primary filter tube 3 and the secondary filter tube 4 are both covered with rubber sleeves. When the membrane column 19 needs to be replaced, the user can first disconnect the water purification pipe 10 from the primary filter tube 3 or the secondary filter tube 4, and then open the rubber sleeve on the top of any filter tube to remove the membrane column 19 and insert a new membrane column 19.

[0038] In this embodiment, optionally, the filter unit can be controlled by a single chip microcomputer, so that the raw water pump 6 and the booster pump 12 can be remotely controlled via wireless signals.

[0039] Embodiment 2

[0040] Since the filter tube and the membrane column are usually arranged as cylinders of nearly equal length, when installing the membrane column, the user usually needs to lift the entire membrane column to the opening of the filter tube before the membrane column can be inserted into the filter tube, which is time-consuming and laborious. Therefore, in order to solve the problem of inconvenient replacement of the membrane column in the prior art and to improve the replacement efficiency, based on the first embodiment, referring to Figure 2-Figure 3 The utility model also discloses a component for improving the efficiency of disassembly and assembly of the membrane column 19, including a first-level filter tube 3 and a second-level filter tube 4 that can be detached and spliced. Specifically, the first-level filter tube 3 and the second-level filter tube 4 are both splicable structures, including an upper tube 14 and a lower tube 15 for splicing to form the first-level filter tube 3 and the second-level filter tube 4. The upper tube 14 and the lower tube 15 are both hollow cylinders with openings, and a slot 17 is annularly provided on the inner wall of one of the openings of the lower tube 15, and a clamping ring 16 corresponding to the slot 17 is provided at either end of the upper tube 14.

[0041] When it is necessary to disassemble and assemble the membrane column 19, the user can first lift the upper tube 14 upwards so that the retaining ring 16 at the bottom of the upper tube 14 can be disconnected from the slot 17. At this time, the upper half of the membrane column 19 originally installed in the filter tube will be exposed to the outside world, and the user only needs to hold the two sides of the membrane column 19 to directly take it out. Subsequently, due to the detachment of the upper tube 14, the lower tube 15 is only half the height of the original filter tube. The user only needs to insert the new membrane column 19 into the opening of the lower tube 15, and then splice the upper tube 14 to the lower tube 14 again to complete the installation of the new membrane column 19, thereby improving the efficiency of disassembly and assembly of the membrane column 19 and saving manpower.

[0042] In another embodiment, corresponding threads 18 are provided on the surface of the clamping ring 16 and the inner wall of the slot 17. Through this arrangement, when the clamping ring 16 is inserted into the slot 17, the user can rotate the upper tube 14 so that the clamping ring 16 can be fixed in the slot 17 through the threads 18 to avoid looseness between the upper tube 14 and the lower tube 15.

[0043] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0044] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
