Description

Technical Field

[0001] The utility model relates to the technical field of RO membrane cleaning, in particular to a movable RO membrane cleaning device. Background Art

[0002] RO is the abbreviation of Reverse Osmosis. Generally, water flows from low concentration to high concentration. Once water is pressurized, it will flow from high concentration to low concentration, which is the so-called reverse osmosis principle: Since the pore size of the RO membrane is one millionth of a hair (0.0001 micron), it is generally invisible to the naked eye, and bacteria and viruses are 5000 times larger than it. Therefore, only water molecules and some mineral ions can pass through (the ions passing through have no benefit or loss orientation), and other impurities and heavy metals are discharged from the wastewater pipe. All seawater desalination processes and astronaut wastewater recycling and treatment use this method, so the RO membrane is also called the high-tech "artificial kidney" outside the body.

[0003] RO membrane is an important component in reverse osmosis technology and is very important in the preparation of ultrapure water. After long-term use, RO membrane is prone to clogging and needs to be cleaned with special cleaning solutions. However, the existing cleaning device cannot clean RO membranes of different sizes, resulting in poor applicability; at the same time, the process of installing and disassembling RO membranes is relatively inconvenient, resulting in time-consuming cleaning of RO membranes and inconvenience for users.

[0027] like Figure 1 As shown, in the present invention, there are four movable casters 2 which are distributed in a rectangular shape. The movable casters 2 are provided with locking pieces for easy fixation and temporary locking.

[0028] like Figure 3 As shown, in the utility model, a guide rod 9.9 that passes through the fixed plate 9.1 is fixedly connected to one side of the semicircular plate 9.2, and the end of the screw rod 9.3 away from the knob 9.4 is rotatably connected to the semicircular plate 9.2 through a bearing 9.10, and the screw rod 9.3 is threadedly connected to the fixed plate 9.1, and a threaded hole for the screw rod 9.3 to pass through is provided on the fixed plate 9.1, and a guide hole for the guide rod 9.9 to pass through is provided on the fixed plate 9.1. When the control knob 9.4 is rotated, the screw rod 9.3 is driven to rotate, and when the screw rod 9.3 is rotated, it slides to one side, thereby driving the semicircular plate 9.2 to move stably to one side.

[0029] like Figure 4As shown, the limit assembly 9.6 in the utility model includes a limit block 9.6.1 slidably connected to the right angle plate 9.5, one side of the limit block 9.6.1 is fixedly connected to a connecting rod 9.6.2 that passes through the side wall of the right angle plate 9.5, and the end of the connecting rod 9.6.2 away from the limit block 9.6.1 is fixedly connected to a pull block 9.6.3, and the limit block 9.6.1 is connected to the side wall of the right angle plate 9.5 by a spring 9.6.4 sleeved on the outside of the connecting rod 9.6.2.

[0030] like Figure 5 As shown, in the utility model, a sliding block 9.11 is fixedly connected to one side of the movable plate 9.7, and a sliding groove 9.12 for the sliding block 9.11 to slide is provided on the side wall of the semicircular plate 9.2, thereby improving the stability of the movable plate 9.7 when sliding.

[0031] like Figure 3 As shown, in the present invention, semicircular openings are provided on the bottom wall of the semicircular plate 9.2 and the movable plate 9.7.

[0032] Working principle: When installing the RO membrane, the utility model first adjusts the distance between the two semicircular plates 9.2 according to the size of the RO membrane, and the control knob 9.4 is rotated to drive the screw 9.3 to rotate. Since the screw 9.3 is threadedly connected to the fixed plate 9.1, and the screw 9.3 is rotatably connected to the semicircular plate 9.2 through the bearing 9.10, and the guide rod 9.9 is used at the same time, when the screw 9.3 rotates, it will slide to one side, thereby driving the semicircular plate 9.2 to move, and then adjust the distance between the two semicircular plates 9.2 to match the distance between the two semicircular plates 9.2 with the RO membrane, and then install the RO membrane between the two semicircular plates 9.2, so that the RO membrane is moved to the side. The two limit blocks 9.6.1 are squeezed downward. Since the upper surface of one side of the limit block 9.6.1 is an inclined surface, when the inclined surface of the limit block 9.6.1 is retracted and squeezed, it will slide to one side. At this time, the spring 2 9.6.4 will be in a compressed state. When the bottom of the RO membrane contacts the movable plate 9.7, pressure will be applied to the movable plate 9.7, so that the spring 1 9.8 is in a compressed state. When the RO membrane is completely installed between the two semicircular plates 9.2, the RO membrane no longer squeezes the limit block 9.6.1. At this time, the elastic potential energy of the spring 2 9.6.4 restores it to its original state, so that the limit block 9.6.1 moves to one side and limits the RO membrane, thereby fixing the RO membrane. The operation is simple and convenient. When cleaning the RO membrane, the cleaning head 8 is installed on the top of the RO membrane, water and cleaning solution are added into the box 1 and mixed evenly, then the water pump 4 is controlled to start, and the clean water in the box 1 passes through the connecting pipe 5, the cleaning pipe 6 and the hose 7, and the cleaning head 8 is used to make the clean water flow out to clean the RO membrane.

[0033] The above implementation modes are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned implementation modes, a person skilled in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the implementation modes of the present invention.
