Description

Technical Field

[0001] The utility model relates to the technical field of drinking water filtration, in particular to an ultrafiltration membrane filtration device for drinking water treatment. Background Art

[0002] Drinking water treatment is the process of filtering water that cannot be drunk directly to make it meet the standards for direct drinking.

[0003] Drinking water treatment equipment in the prior art mostly uses ultrafiltration membranes for ultrafiltration. The mechanism of ultrafiltration refers to the combined effect of mechanical screening on the membrane surface, membrane pore blocking, and adsorption on the membrane surface and membrane pores. The ultrafiltration membrane can retain colloidal-sized particles in the water, while water and low molecular weight solutes are allowed to pass through the membrane.

[0004] However, the ultrafiltration membrane in the drinking water treatment device in the prior art is very easy to be blocked by dirt. Once the ultrafiltration membrane is blocked by dirt, the filtering effect of the ultrafiltration membrane is reduced. Therefore, the staff is required to remove the ultrafiltration membrane for cleaning. Since manual cleaning takes a long time and the cleaning effect is not ideal, a new ultrafiltration membrane needs to be replaced when the blockage is serious, which increases the production cost and is time-consuming and labor-intensive. Therefore, an ultrafiltration membrane filtration device for drinking water treatment is proposed to solve the above problems. Utility Model Content

The conveying member 2 includes a pump body 21 with one end fixedly connected to one side of the filter bin 1. The water inlet end of the pump body 21 is connected to a pumping pipe 22, and the water outlet end of the pump body 21 is connected to a drain pipe 23 with one end penetrating through and extending to the inside of the support tube 61, so that the started pump body 21 can pump the water to be filtered into the filter bin 1 through the pumping pipe 22 and the drain pipe 23.

[0027] In this embodiment, since the ultrafiltration membrane 611 is fixed in the mounting hole of the support plate 5, and the support plate 5 can be inserted between the cover plate 69 and the inner wall of the filter chamber 1 through the long strip 612, and is blocked and limited by the blocking rod 43 on the pull rod 42, the blocking rod 43 can be separated from the support plate 5 by pulling the pull rod 42, so the support plate 5 and the ultrafiltration membrane 611 can be pulled out, which increases the convenience for the operator when replacing and cleaning.

[0028] Among them, the blocking rod 43 and the pull rod 42 are both L-shaped, and the upper end of the support plate 5 is provided with a blocking groove located outside the blocking rod 43. The blocking rod 43 extending to the inside of the blocking groove is used to limit and block the support plate 5 inserted into the filter chamber 1.

[0029] See also Figure 2-3 In this embodiment, a cleaning member 6 is provided inside the filter bin 1;

[0030] The cleaning member 6 comprises a rotating rod 62 rotatably connected to the inner bottom wall of the filter bin 1 at one end, a supporting tube 61 having one end penetrating the supporting plate 5 is fixedly connected to the outer side of the rotating rod 62, a stopper 64 located on the outer side of the rotating rod 62 is fixedly connected to the inner side of the supporting tube 61, a paddle 63 located above the stopper 64 is fixedly connected to the outer side of the rotating rod 62, an ultrafiltration membrane is fixedly installed on the inner side of the supporting plate 5, a partition 69 is fixedly connected to the inner wall of the filter bin 1, a liquid level gauge 68 is fixedly installed on the inner wall of the filter bin 1, a second supporting plate 610 located on the outer side of the supporting tube 61 is fixedly connected to the inner wall of the filter bin 1, a long strip 612 having one end extending to the second supporting plate 610, the partition 69 and the inside of the filter bin 1 is fixedly connected to the supporting plate 5, and a cleaning rod 65 is fixedly connected to the outer side of the supporting tube 61.

[0031] In this embodiment, when the pump body 21 pumps the water flow to be filtered to the water outlet end of the drain pipe 23 for discharge, the flushing blade 63 can drive the rotating rod 62 and the support tube 61 to rotate, and then drive the cleaning rod 65 on the outside of the support tube 61 to clean and filter the ultrafiltration membrane 611, so as to automatically clean the ultrafiltration membrane 611, thereby reducing the possibility of clogging of the ultrafiltration membrane 611, that is, reducing the frequency of cleaning and replacement, thereby improving the filtering effect while reducing production costs.

[0032] Among them, the inner wall of the support cylinder 61 is provided with a drainage hole located between the paddle 63 and the block 64, one side of the partition 69 is connected to a connecting pipe 66, and the other side of the filter chamber 1 is connected to an outlet pipe 67. Valves are provided on the outside of the outlet pipe 67 and the connecting pipe 66. The valve on the connecting pipe 66 is a one-way valve, which allows the filtered water to flow through the connecting pipe 66 to the other side of the partition 69 and then be discharged through the outlet pipe 67.

The support plate 5 is stably plugged in by extending the long strips 612 into the support grooves, and the sealing of the support plate 5 after plugging in is improved.

[0034] It should be noted that the liquid level meter 68 is electrically connected to the control panel 3. When the liquid level monitored by the liquid level meter 68 reaches a set height, that is, the height at which the liquid level meter 68 is located, the pump body 21 can be controlled through the control panel 3 to stop delivering water. After the filtered water is discharged through the water storage pipe 67, the pump body 21 can be controlled to deliver water again for filtering processing, thereby improving the overall intelligence level.

[0035] The working principle of the above embodiment is:

[0036] Since the rotating rod 62 is fixed with a paddle located between the block 64 and the drain pipe 63, when the pump body 21 pumps the water to be filtered to the water outlet of the drain pipe 23 for discharge, the rotating rod 62 and the support tube 61 can be driven to rotate by flushing the paddle 63, so as to drive the cleaning rod 65 on the outside of the support tube 61 to clean and filter the ultrafiltration membrane 611, so as to automatically clean the ultrafiltration membrane 611, thereby reducing the possibility of clogging of the ultrafiltration membrane 611, that is, reducing the frequency of cleaning and replacement, thereby improving the filtering effect and reducing the production cost. Since the ultrafiltration membrane 611 is fixed in the mounting hole of the support plate 5, and the support plate 5 can be inserted between the cover plate 69 and the inner wall of the filter chamber 1 through the long strip 612, and is blocked and limited by the stop rod 43 on the pull rod 42, the stop rod 43 can be driven to separate from the support plate 5 by pulling the pull rod 42, so that the support plate 5 and the ultrafiltration membrane 611 can be extracted, thereby increasing the convenience of the operator when replacing and cleaning.
