Description

Technical Field

[0001] This utility model relates to the technical field of reverse osmosis membrane water treatment equipment, and in particular to a reverse osmosis membrane water treatment device. Background Technology

[0002] Reverse osmosis water treatment equipment uses a pressure-driven system to generate continuous mechanical force, propelling raw water into the membrane module housing under the drive of a high-pressure metal pump. A stainless steel piping network evenly distributes the water flow to the spirally wound membrane module. When the liquid passes through the composite polyamide membrane with its densely distributed micropores, the cross-linked polymer chains inside the membrane layer form a molecular-level sieve structure. Mechanical pressure forces water molecules to penetrate the membrane layer gaps, while dissolved substances, due to their volume being larger than the membrane pore size, are mechanically retained. The retained concentrate is collected in the wastewater channel through a corrosion-resistant alloy guide plate, while the permeate is discharged through a food-grade PVC collection pipe. The entire system achieves pressure regulation through flange-connected pipe and valve assemblies and is equipped with a pressure protection device with bronze gear drive to prevent overpressure on the membrane housing. The pretreatment unit includes multi-stage stainless steel filters to intercept suspended solids, and the post-treatment stage uses an ultraviolet sterilizer to inactivate microorganisms. All moving parts are linked by an electric motor driving a gearbox. Existing water treatment equipment is as follows:

[0003] For example, patent publication number CN218620552U discloses a reverse osmosis water treatment device, including a main body, a receiving mechanism, and a cleaning mechanism. The receiving mechanism is located at the outer end of the main body, and the cleaning mechanism is located at the inner end of the main body. The cleaning mechanism includes a filter screen, a cleaning motor, a lead screw, a movable block, a mounting frame, a cleaning brush, an inclined plate, a collection box, a slide rail, and a slider. The cleaning motor is movably mounted on the outer side of the filter screen, the lead screw is fixedly mounted on the transmission end of the cleaning motor, the movable block is movably mounted on the outer end of the lead screw, the mounting frame is movably mounted on the lower end of the movable block, and the cleaning brush is fixedly mounted on the lower end of the mounting frame. This reverse osmosis water treatment device, with the simultaneous movement of the movable block and the cleaning brush, can clean impurities or large particles attached to the surface of the filter screen, allowing the precision filter to meet daily cleaning requirements without easily clogging, thus improving the water treatment effect of the device.

[0004] In actual operation, the above-mentioned utility model mainly filters water through the reverse osmosis membrane inside the reverse osmosis tube to achieve water treatment. Although the above solution can treat water, there are some large particles and impurities in the water. If the water comes into direct contact with the reverse osmosis membrane, over time, a large number of particles and impurities will easily accumulate at the inlet end of the reverse osmosis tube, causing the reverse osmosis membrane to become clogged. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art and to propose a reverse osmosis membrane water treatment device that can filter water.

[0006] To achieve the above objectives, this utility model proposes a reverse osmosis membrane water treatment device, comprising: a support frame and a plurality of reverse osmosis tubes mounted on the support frame and each tube carrying a reverse osmosis membrane.

[0007] It also includes: filter box, lifting platform, filter screen and cleaning box;

[0008] The filter box is fixedly connected to the bracket. One end of the filter box is connected to the external water inlet pipe, and the other end of the filter box is connected to the water inlet of the reverse osmosis pipe through the delivery pipe.

[0009] The lifting seat is driven to move up and down and is connected to the filter box. The filter screen is driven to swing downward and is connected to the lifting seat. The water inlet pipe and the filter screen are arranged opposite to each other.

[0010] The cleaning box is slidably connected to the filter box, and one end of the cleaning box can be moved onto the filter box.

[0011] Sealing plates are fixedly connected to the side walls at both ends of the filter box. One of the sealing plates can be attached to the side wall of the filter box, while the other sealing plate can be attached to the inner wall of the filter box.

[0012] Preferably, a high-pressure nozzle is fixedly connected to the inner wall of the filter box. One end of the high-pressure nozzle is connected to an external water supply pipe. The high-pressure nozzle is located above the filter screen and the cleaning box, and the output end of the high-pressure nozzle is positioned opposite to the filter screen.

[0013] Preferably, a water guide plate is fixedly connected to the inner wall of the cleaning box at an angle.

[0014] Preferably, the cleaning box is connected to a drain pipe at one end outside the filter box. The drain pipe is located above the guide plate and a manual valve is fixedly connected to the drain pipe.

[0015] Preferably, a sealing strip is fixedly connected to the inner wall of the filter box, and the sealing strip can be attached to the top of the filter screen.

[0016] Preferably, a sealing ring is fixedly connected to the side wall of the sealing plate, and the sealing ring can be attached to the filter box.

[0017] Preferably, a support slide rod is fixedly connected inside the filter box, and the support slide rod is slidably connected to the sealing plate.

[0018] The beneficial effects of this utility model compared with the prior art are as follows:

[0019] 1. A mechanical filter screen that can be raised, lowered, and oscillating is added before the reverse osmosis membrane treatment unit. The water to be treated first impacts the filter screen, effectively intercepting large particulate impurities and suspended solids in the water. This pre-filtration significantly reduces the solid particles that subsequently enter the precision reverse osmosis membrane, significantly reducing the risk of impurities deposited at the inlet end of the reverse osmosis tube and the reverse osmosis membrane itself being clogged, protecting the core reverse osmosis membrane components and extending their service life;

[0020] 2. When the filter needs cleaning, the electric push rod drives the lifting seat to descend, and at the same time the motor drives the filter to tilt downward, forming an angle that facilitates sewage discharge. The fixedly installed high-pressure nozzle uses high-pressure water generated by an external water source to precisely rinse the surface of the filter in the tilted state. The impurities and particles washed off naturally slide down into the specially designed sliding cleaning box below for storage under the action of gravity.

[0021] 3. The cleaning box containing impurities is driven by another set of electric push rods and can slide inside the filter box. When impurities need to be removed, the push rods push one end of the cleaning box out of the filter box to an external, operable position, making it convenient for operators to directly clean the impurities accumulated inside the box. When the cleaning box slides and after resetting, the fixed sealing plate and sealing ring fit tightly against the box body, effectively reducing water leakage and impurity overflow, ensuring that the sealing performance of the filter box is not affected before and after cleaning operations. The support slide rod provides stable mechanical guidance for the sliding of the cleaning box.

[0022] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0030] like Figures 1 to 2 A reverse osmosis membrane water treatment device includes: a support 1 and a plurality of reverse osmosis tubes 2 disposed on the support 1 and equipped with reverse osmosis membranes, wherein the reverse osmosis membranes in the reverse osmosis tubes 2 can filter water and increase the cleanliness of the water.

[0031] The processing device in this utility model also includes: a filter box 3, a lifting seat 4, a filter screen 5, and a cleaning box 6;

[0032] The filter box 3 is fixedly connected to the bracket 1. One end of the filter box 3 is connected to the external water inlet pipe 10, and the other end of the filter box 3 is connected to the water inlet of the reverse osmosis pipe 2 through the delivery pipe 9. The water inlet pipe 10 is used to transport the water to be filtered into the filter box 3, while the delivery pipe 9 is used to transport the pre-filtered water into the reverse osmosis pipe 2. The delivery pipe 9 is supplied with liquid by the liquid pump 18, which is located on the bottom surface of the filter box and is connected to the delivery pipe, so that the liquid pump can transport water into the delivery pipe. It is worth mentioning that the lifting seat 4 is driven to move up and down and is connected to the filter box 3. The filter screen 5 is driven to swing downward and is connected to the lifting seat 4. The water inlet pipe 10 and the external water inlet pipe 10 are connected to the external water inlet pipe 10 through the delivery pipe 9. The filter screens 5 are arranged opposite each other. The lifting seat 4 is driven by an electric push rod, which is fixedly connected to the lifting seat 4 and its output shaft is fixedly connected to the lifting seat 4. Therefore, the electric push rod can drive the lifting seat 4 to move the filter screens 5, thereby adjusting the height of the filter screens 5. The filter screens 5 are driven by a motor, which is fixedly connected inside the lifting seat 4 and its output shaft is fixedly connected to the filter screens 5, thereby achieving the swinging of the filter screens 5. When water enters the filter box 3, the filter screens 5 can filter the water, thereby reducing the generation of particles in the water. When the filter screens 5 need to be cleaned, the lifting seat 4 descends, and the swinging of the filter screens 5 causes the filter screens 5 to tilt downward.

[0033] When the filter screen 5 tilts downwards, a high-pressure nozzle 8 is fixedly connected to the inner wall of the filter box 3. One end of the high-pressure nozzle 8 is connected to the external water supply pipe 11. The high-pressure nozzle 8 is located above the filter screen 5 and the cleaning box 6, and its output end is opposite to the filter screen 5. The cleaning box 6 is slidably connected inside the filter box 3, and one end of the cleaning box 6 can move onto the filter box 3. Therefore, water from the external water supply pipe 11 is transmitted through the high-pressure nozzle 8 to rinse the filter screen 5. The impurities on the rinsed filter screen 5 will enter the cleaning box 6 for storage. Once the filter screen 5 is cleaned, Since the cleaning box 6 is driven to slide by an electric push rod, the output shaft of the electric push rod, which is fixedly connected to the filter screen 5, will drive the cleaning box 6, which is fixedly connected to its output shaft, to move. This causes one end of the cleaning box 6 to move to the outside, so that personnel can clean the impurities inside the cleaning box 6. When the cleaning box 6 moves to the outside, since sealing plates 7 are fixedly connected to the side walls at both ends of the filter box 3, one sealing plate 7 can fit against the side wall of the filter box 3, and the other sealing plate 7 can fit against the inner wall of the filter box 3. The sealing plates 7 can fit against the inner wall of the filter box 3 to increase the sealing effect of the filter box 3.

[0034] Specifically, a water guide plate 12 is fixedly connected to the inner wall of the cleaning box 6 at an angle. A drain pipe 13 is fixedly connected to one end of the cleaning box 6 outside the filter box 3. The drain pipe 13 is located above the guide plate and a manual valve 14 is fixedly connected to the drain pipe 13. The water guide plate 12 is used to guide the water so that the water can enter the drain pipe 13. At this time, the personnel open the manual valve 14 to discharge the water in the cleaning box 6.

[0035] Specifically, a sealing strip 15 is fixedly connected to the inner wall of the filter box 3, and the sealing strip 15 can be attached to the top of the filter screen 5. The sealing strip 15 is attached to the filter screen 5 to seal the gap between the filter screen 5 and the filter box 3;

[0036] Specifically, sealing rings 16 are fixedly connected to the side walls of the sealing plate 7. The sealing rings 16 can be attached to the filter box 3. A support slide rod 17 is fixedly connected inside the filter box 3. The support slide rod 17 is slidably connected to the sealing plate 7. The sealing rings 16 are used to increase the sealing effect between the filter screen 5 and the sealing plate 7, while the support slide rod 17 is used to support the filter box 3.

[0037] The working principle of this utility model is as follows: External water source is directed towards the filter screen 5 through the inlet pipe 10. The impact force of the water flow causes the filter screen 5 to filter the water, intercepting larger particulate impurities. The lifting seat 4, driven by an electric push rod, drives the entire filter screen 5 unit to move up and down reciprocally.

[0038] The filtered water enters the reverse osmosis tube group 2 through the delivery pipe 9. The pressure difference causes water molecules to penetrate the reverse osmosis membrane to form pure water, while the retained substances are discharged with the concentrated water. When the filter screen 5 accumulates scale, the lifting seat 4 descends to the cleaning position, and the motor drives the filter screen 5 to tilt the screen surface downward at a 45-degree angle. At this time, the high-pressure nozzles 8 spray water in a fan shape to wash the screen surface. The removed impurities slide along the inclined screen surface into the cleaning box 6 below, and the water guide plate 12 at the bottom of the cleaning box 6 guides the wastewater towards the drain pipe 13.

[0039] The cleaning box 6 slides horizontally via another set of electric push rods: during cleaning, the box extends out of the device, and the sealing plate 7 moves with the box to fill the gaps and maintain the system's airtightness; during resetting, the sealing ring 16 is tightly fitted against the inner wall of the filter box 3 to prevent leakage. The support slide rod 17 always provides axial guidance for the cleaning box 6 to prevent tilting. The sealing strip 15 forms an elastic seal with its top when the filter screen 5 is in the working position.

[0040] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
