Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water purification equipment, and particularly relates to an ultrafiltration water purifier that realizes forward and reverse flushing through the steering of an internal valve. Background Art
[0002] An ultrafiltration water purifier is a type of water purification equipment. Compared with traditional water purifiers, it has a higher water purification effect. Its main water purification components are filter nets or filter barrels, and it also has the effect of automatically cleaning the filter nets or filter barrels.
[0003] A Chinese patent application (or patent) with the publication number of CN211724871U discloses a pre-filter with a backwashing function and a backwashing water distribution part, which includes: a machine head with a water inlet and a water outlet, a filter bottle cooperating with the machine head and having a closable sewage discharge part, a filtering and backwashing mechanism is arranged in the filter bottle, the gap between the outside of the filtering and backwashing mechanism and the filter bottle forms a raw water cavity, the inside of the filtering and backwashing mechanism forms a purified water cavity, the filtering and backwashing mechanism includes a filtering element and a coaxially arranged backwashing element, the raw water cavity can be communicated with the water inlet of the filtering element, the purified water cavity is communicated with the water outlet, the backwashing element can axially move relative to the filtering element driven by a pressure difference, a backwashing water distribution part with a smaller flow diameter to generate a larger flow velocity is arranged in the backwashing element, and the backwashing water distribution part can freely rotate in the backwashing element under the impact of water flow. The utility model has a reasonable structural design and is easy to assemble, and can realize reverse flushing by switching the flow channel.
[0004] For the above-mentioned pre-filter with a backwashing function and a backwashing water distribution part, the way of switching the flow channel is that "the backwashing filter screen skeleton can axially move synchronously relative to the filtering element with the backwashing filter screen body driven by a pressure difference. After axially moving downward for a certain stroke, the elastic resetting part is compressed, the lower working surface of the assembly part can close the water inlet end cover, and the backwashing filter screen body is exposed to realize the flow channel switching". It can be seen that one of the most important components during the backwashing process is the elastic reset key. Reverse flushing is realized through the compression of the elastic resetting part, and forward flushing is carried out when the elastic resetting part loses the compression force and resets. The elastic resetting part is a spring structure, and its elastic mode is through the way of opening the sewage discharge part to make the pressure drop at both ends of the sewage discharge hole of the lower sealing body of the backwashing filter screen. And this pressure drop will gradually decrease with the increase of the opening time of the sewage discharge part, and finally lose the pressure drop. Furthermore, the backwashing process is uncontrollable and will gradually decrease until it is lost. Therefore, we provide an ultrafiltration water purifier that realizes forward and reverse flushing through the steering of an internal valve to solve the problems that appear above.

[0025] Embodiment 1
[0026] Please refer to Figure 1 , the present invention is an ultrafiltration water purifier that realizes forward and reverse flushing through the turning of a built-in valve, including a body 1. A horizontal support 2 and a vertical skirt support 3 are arranged on the body 1. By using the horizontal support 2 and the vertical skirt support 3, two support states of horizontal and vertical for the body 1 can be realized.
[0027] Specifically, the bottom side wall of the body 1 is connected to the horizontal support 2 by bolts, and the vertical skirt support 3 is threadedly connected to the tail of the body 1.
[0028] Furthermore, two horizontal supports 2 are provided in total, and the two horizontal supports 2 are respectively arranged at both ends of the body 1.
[0029] The operation process of this embodiment is as follows: when the width of the assembly space is small, the body 1 is vertically erected so that the vertical skirt support 3 faces downwards. At this time, the vertical skirt support 3 will contact the ground and thus support the body 1. When the height of the assembly space is small, the body 1 is placed horizontally so that the body 1 is parallel to the ground and the horizontal support 2 faces downwards for contacting the ground, and then the body 1 can be supported.
[0030] Embodiment 2
[0031] Please refer to Figures 2-3 , on the basis of the specific Embodiment 1, a filter element 101 arranged in the body 1 is further provided. An built-in valve 7 is also installed at the head water inlet end of the filter element 101. There is a gap between the filter element 101 and the inner wall of the body 1. The built-in valve 7 is arranged inside the head cover 4 of the body 1, and the handle 703 of the built-in valve 7 is located outside for easy operation. When performing forward and reverse flushing, it can be carried out by rotating the handle 703. The entire process and time of forward water outlet and reverse flushing can be controlled manually.
[0032] Specifically, a filter element 101 is provided inside the body 1, and a water purification tank 102 is arranged between the filter element 101 and the body 1. A hood 4 is sleeved on the head of the body 1, and a water inlet pipe 5 is installed on the upper side wall of the hood 4. A water outlet pipe 6 is installed on the outer wall of the body 1 beside the water inlet pipe 5. An internal valve 7 is also installed inside the hood 4.
[0033] Furthermore, at the inner end of the head of the filter element 101 located inside the hood 4, a water inlet cover 101a is threadedly connected. A sewage outlet 101b is provided at the tail of the filter element 101, and a water purification port 101c is also opened on the outer wall beside the filter element 101.

Among them, the valve body 701 is installed at the middle position of the water inlet pipe 5, and the valve body 701 is connected to the handle 703 through the valve rod 702, and the handle 703 is arranged outside the hood 4.
[0034] The operation process of this embodiment is as follows:
[0035] During normal water production, rotate the handle 703 of the internal valve 7 to make it in a horizontal state. Water enters the pipe through the inlet end of the water inlet pipe 5 and is introduced into the inside of the filter element 101. Then, after being filtered by the filter element 101, the purified water flows out from the inside of the filter element 101 into the outer water purification tank 102, and then flows out from the water outlet pipe 6.
[0036] During reverse flushing, rotate the handle 703 of the internal valve 7 to make it in a vertical state, that is, the section between the filter element 101 and the water inlet pipe 5 is in a closed state. Water can only flow out from the end of the water inlet pipe 5 and enter the water purification tank 102 between the body 1 and the filter element 101. Then, this part of the water enters the inside of the membrane through the outer surface of the membrane of the filter element 101, that is, the filter membrane of the filter element 101 is flushed. The sewage flushed from the filter membrane on the side wall of the filter element 101 flows out from the sewage outlet 101b at the end of the filter element 101.
