Description

Technical Field

[0001] The utility model relates to the field of water purification, in particular to an assembled pre-water purification system with an automatic backwashing function. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for the clean quality of tap water, so the tap water purification system has gradually become an important part of home decoration appliances. The existing technical solution is the traditional water purification system pre-filter + central water purification system + soft water system + RO water purification system.

[0003] Disadvantages of existing technology:

[0004] ① The traditional water purification system does not have an automatic backwash cleaning function, which affects the service life of the RO water purification system.

[0005] ② Traditional water purification systems require on-site assembly of scattered individual components, and all materials and equipment must be prepared. The on-site conditions are complex, and insufficient parts preparation often leads to multiple on-site installations, resulting in increased installation costs and reduced installation efficiency. Traditional pre-water purification systems also take up too much space, resulting in wasted space and inconvenient maintenance.

[0006] ③ The traditional water purification system has a pre-filter screen + central water purification system + soft water system + RO water purification system. Multiple systems are connected in series, so the resistance is large and the flow rate is small.

[0007] ④ Traditional water purification systems do not have leakage protectors, which poses a great safety hazard when leakage occurs.

[0008] ⑤ Traditional water purification systems have low filtration accuracy, resulting in sediment sedimentation in the soft water and at the bottom of the central water tank, causing secondary pollution. Traditional water purification systems also have high consumables and maintenance costs.

In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other. Fixing methods not described in this article can be any fixing method such as threaded fixing, bolt fixing, or gluing.

[0049] Example 1: Combined with all the drawings; an assembled pre-water purification system with automatic backwashing function, characterized in that:

[0050] The water purification system includes a mounting bracket 16, on which ultrafiltration bottles A10 and B14 are fixed, and intermediate filtration bottles A6 and B8 are also fixed.

[0051] The water inlet 19 of the municipal water pipe is connected to the water leakage protector 17, and the branch pipe of the water leakage protector 17 is connected in parallel to the intermediate filter bottle A6 and the intermediate filter bottle B8;

[0052] There is a common water outlet pipe in the middle of the intermediate filter bottle A6 and the intermediate filter bottle B8;

[0053] The common water outlet pipe is connected to an electric two-way valve 1 and an electric two-way valve 2, which are respectively connected to the ends of ultrafiltration bottle A10 and ultrafiltration bottle B14. At the other ends of ultrafiltration bottle A10 and ultrafiltration bottle B14, an electric two-way valve 3 11 and an electric two-way valve 4 12 are arranged;

[0054] A water outlet 18 for receiving a water pipe is also arranged between ultrafiltration bottle A10 and ultrafiltration bottle B14.

[0055] The substantial technical effects and implementation process of this technical solution, i.e., the basic functions, are as follows:

[0056] Normal working mode water route map reference Figure 5The municipal water pipe or water pump is connected to the water inlet 19 of the municipal water pipe through a pipe. The tap water passes through the patent first through the leakage protector 17 (a leakage alarm will be placed below the patent. When a leakage is detected, a signal will be sent to the leakage protector 17, and the leakage protector 17 will be closed) and then enters the intermediate filter bottle A6 and the intermediate filter bottle B8 respectively through the water pipe tee and two parallel water pipes;

[0057] (At this time, the tap water will also pass through the anti-water hammer expansion tank 3, which can effectively prevent the unstable water pressure of the tap water, especially when the water pressure is too high, and release the soft water pressure to protect the safety of the pipeline and the subsequent equipment) After purification, the tap water is merged into one stream of water, and then enters the ultrafiltration bottle A10 and the ultrafiltration bottle B14, and finally flows out of the clean water through the water outlet 18 of the water pipe, and then enters the soft water system and the R0 water purification system through the water pipe. Finally, the purified clean water is delivered to the end user such as the faucet through the water pipe.

[0058] At this time, the valve working mode is:

[0059] One state of the electric two-way valve is open;

[0060] The second state of the electric two-way valve is open;

[0061] The three states of the electric two-way valve are closed;

[0062] The four states of the electric two-way valve are closed;

[0063] Sewage outlet (normally open, closed during maintenance).

[0064] Example 2: As a further improved solution or parallel solution or optional independent solution, the working principle of ultrafiltration bottle A is as follows:

[0065] The municipal tap water pipe or water pump is connected to the water inlet 19 of the municipal tap water pipe through a pipe. The tap water passes through the patent first through the leakage protector 17 (a leakage alarm will be placed below the patent. When a leak is detected, a signal will be sent to the leakage protector 17, and the leakage protector will be closed). Then, the two water pipes are connected in parallel through the water pipe tee and enter the intermediate filter bottle A6 and the intermediate filter bottle B8 respectively (at this time, the tap water will also pass through the anti-water hammer expansion tank 3, which can effectively prevent the unstable water pressure of the tap water, especially when the water pressure is too high, to release the soft water pressure, thereby protecting the pipeline and the subsequent devices). After purification, the tap water is merged into one water channel. This process is consistent with the normal working mode:

[0066] At this time, through the dual-way time controller 20, (the backwash cycle can be set, the default is one week backwash, one time for 1 minute) when the user-set time is reached, the dual-way time controller gives a control signal, at this time the electric two-way valve 2 is closed, the electric two-way valve 1 is opened, the electric two-way valve 3 is opened, and the electric two-way valve 4 is closed. At this time, the water passes through the ultrafiltration B and the purified water can only flow into the ultrafiltration bottle B and then be discharged through the sewage outlet 13. For details, see the backwash water route diagram of the ultrafiltration bottle A:

[0067] At this time, the valve working mode is

[0068] Electric two-way valve one state is open

[0069] The second state of the electric two-way valve is closed

[0070] The three states of the electric two-way valve are open

[0071] Electric two-way valve four states are closed

[0072] Sewage outlet (normally open, closed during maintenance)

[0073] When the backwash of ultrafiltration bottle A reaches 1 minute (the time can be customized by the user), the dual-way time controller 20 gives a control signal. At this time, the electric two-way valve 2 opens, the electric two-way valve 1 closes, the electric two-way valve 3 closes, and the electric two-way valve 4 opens. At this time, the water passes through the ultrafiltration B and the purified water can only flow into the ultrafiltration bottle B and then be discharged through the sewage outlet 13.

[0074] For details, please refer to the backwash water route diagram for ultrafiltration bottle B:

[0075] At this time, the valve working mode is

[0076] One state of the electric two-way valve is closed;

[0077] The second state of the electric two-way valve is open;

[0078] The three states of the electric two-way valve are closed;

[0079] The four states of the electric two-way valve are open;

[0080] Sewage outlet (normally open, closed during maintenance);

[0081] When the backwashing of ultrafiltration bottle B reaches 1 minute (the time can be customized by the user), the dual-channel time controller 20 sends a control signal to restore to the normal working mode.

[0082] Example 3: As a further improved solution, a parallel solution, or an optional independent solution, ultrafiltration bottles A10 and B14 are also connected to a water hammer expansion tank 3.

[0084] Example 5: As a further improved solution, parallel solution, or optional independent solution, electric two-way valve 1, electric two-way valve 2, electric two-way valve 3, and electric two-way valve 4 are all automatic valves. The substantial technical effect and implementation process of this technical solution are as follows: automatic control is achieved.

[0085] Example 6: As a further improved solution, a parallel solution, or an optional independent solution, electric two-way valve 1, electric two-way valve 2, electric two-way valve 3, and electric two-way valve 4 are communicatively connected to a time-controlled switch, which is a microcomputer-controlled time-controlled switch. The substantial technical effects and implementation process of this technical solution are as follows: intelligent control and automated flushing are achieved.

[0086] Example 7: As a further improved solution or parallel solution or optional independent solution, the water outlet 18 of the water pipe is connected to the soft water system and the RO water purification system. The substantial technical effect and implementation process of the technical solution here are as follows: it can comprehensively clean water.

[0087] Example 8: As a further improved, parallel, or independent solution, ultrafiltration bottles A10 and B14, and intermediate filtration bottles A6 and B8 are all secured to mounting bracket 16 via quick-install clamps. The substantial technical effects of this technical solution and its implementation are as follows: Similar securing methods are within the scope of this patent. The filtration apertures of ultrafiltration bottles A10 and B14, and intermediate filtration bottles A6 and B8 are adjustable, allowing for flexible adjustments based on local water quality.

[0088] Example 9: As a further improved solution, a parallel solution, or an optional independent solution, a drain port 13 is provided between intermediate filter bottles A6 and B8 via a tee. This drain port 13 is normally open and closed during maintenance.
