[0035] The following will be described in detail in combination with the accompanying drawings Figures 1-6 The present application is further described in detail.

[0036] The present application discloses a kind of tap water pretreatment device, refer to Figure 1 , tap water pretreatment device includes pretreatment unit 5, the water inlet end of pretreatment unit 5 is connected with municipal pipe network 1, the water supply end of municipal pipe network 1 is equipped with pressure sensor, pressure sensor is electrically connected with control component, water supply end is respectively connected with monitoring component 2 and booster component 3, when the detection value of pressure sensor is greater than the set value of control component, water supply end is communicated with pretreatment unit 5 by monitoring component 2, when the detection value of pressure sensor is less than the set value of control component, water supply end is communicated with pretreatment unit 5 by booster component 3.

[0037] The pretreatment unit 5 in the tap water pretreatment device is used for preliminary treatment of the incoming tap water, removing impurities, suspended solids, part of microorganisms and the like in the water, improving the water quality, and providing water source meeting certain standards for subsequent water use link. The municipal pipe network 1 serves as a conveying carrier for tap water from the water plant to the user, and continuously conveys the tap water source preliminarily purified by the water plant to the pretreatment unit 5, ensuring the continuity and stability of tap water supply, providing sufficient water source for the pretreatment unit 5, and maintaining the continuous operation of the entire pretreatment system.

[0038] The pressure sensor can be used to monitor the water pressure at the water supply end of the municipal pipe network 1 in real time, and convert the water pressure data into an electrical signal output to the control component, providing accurate water pressure information for the system of the device, so that the system can make judgments and decisions according to the actual water pressure, realize intelligent control, and then realize energy-saving operation.

[0039] When the water pressure detected by the pressure sensor is greater than the set value in the control component, the monitoring component 2 builds a water flow channel between the water supply end of the municipal pipe network 1 and the pretreatment unit 5, so that the tap water can directly flow into the pretreatment unit 5, fully utilizing the higher water pressure of the municipal pipe network 1 itself, avoiding unnecessary pressure relief and pressure boosting operation, reducing energy consumption and operation cost, and at the same time ensuring that the tap water can smoothly enter the pretreatment unit 5 for treatment.

[0040] When the water pressure detected by the pressure sensor is less than the set value of the control component, the booster component 3 starts to boost the tap water input by the municipal pipe network 1, so that the water pressure is raised to a level meeting the requirements of the pretreatment unit 5, and then the boosted water is delivered to the pretreatment unit 5, ensuring that the pretreatment unit 5 can still obtain stable and sufficient pressure water source under the condition of insufficient water pressure of the municipal pipe network 1, ensuring that the pretreatment work is not affected by water pressure fluctuation and stably operates, thereby ensuring the normal operation of the entire water use system.

[0041] The tap water pretreatment device realizes efficient utilization and intelligent pretreatment of tap water of the municipal pipe network 1 by adding the monitoring component 2 and the booster component 3 between the municipal pipe network 1 and the pretreatment unit 5. Through the pressure sensor, the water pressure of the municipal pipe network 1 is monitored in real time, and according to the water pressure, the working state of the monitoring component 2 and the booster component 3 is controlled by the control component, so that when the water pressure of the municipal pipe network 1 is sufficient, the natural water pressure is directly utilized for pretreatment, reducing energy waste; when the water pressure is insufficient, the pressure is boosted in time to ensure the stable operation of the pretreatment unit 5. This way not only improves the energy utilization efficiency and reduces the operation cost, but also guarantees the stability of the water quality after pretreatment, meets the demand for tap water pretreatment in different scenarios, compared with the traditional pretreatment system, without the need for a large water storage tank and subsequent cleaning of the water storage tank, has higher reliability and energy saving, and can better adapt to the water pressure change of the municipal pipe network 1, providing stable water source guarantee for subsequent water use.

[0042] Reference Figures 1-4 In the device, the control component is set to use the natural water pressure of the municipal pipe network 1 directly for the pressure of the pretreatment unit 5, and when the water pressure detected by the pressure sensor is less than the set value of the control component, the booster component 3 is started. The booster component 3 includes a fixed seat 31 and a fixed cylinder 32, the fixed seat 31 is rotatably connected with a crankshaft 33, the main shaft of the crankshaft 33 is connected with a driving part 34, the driving part 34 is installed on the fixed seat 31, the secondary shaft of the crankshaft 33 is rotatably connected with a first connecting rod 35, the other end of the first connecting rod 35 is rotatably connected with a second connecting rod 36 and an action rod 37, the other end of the action rod 37 is rotatably connected with a piston column 321, the piston column 321 ascends and descends in the fixed cylinder 32, the fixed cylinder 32 is connected with the water supply end, and the adjusting component 4 is installed on one side of the fixed cylinder 32, and the adjusting component 4 is drivingly connected with the second connecting rod 36.

[0043] The fixed seat 31 serves as the basic support structure of the booster component 3, provides mounting positions for other components such as the crankshaft 33 and the driving part 34, ensures the relative position of each component fixed, and the fixed cylinder 32 is used to accommodate the piston column 321, provides space for the lifting movement of the piston column 321, and is connected with the water supply end of the municipal pipe network 1, which is the water boosting working chamber. The fixed cylinder 32 can ensure the sealing of the movement of the piston column 321, so that the piston column 321 can effectively boost the water in the cylinder when ascending and descending in the fixed cylinder 32, prevent water leakage, and improve the boosting efficiency.

[0044] The crankshaft 33 can convert the rotary motion provided by the driving part 34 into the reciprocating linear motion of the piston column 321, receive power from the driving part 34 through the main shaft, drive the first connecting rod 35 connected with it to move, realize the conversion of the motion form, provide power source for the movement of the piston column 321, and then realize the boosting function of the booster component 3.

[0045] The driving part 34 provides power for the entire booster component 3, and the driving part 34 can drive the crankshaft 33 to rotate. The driving part 34 can adopt a motor to convert electrical energy into mechanical energy, providing continuous and stable power for the boosting process. The power and speed of the motor determine the rotation speed of the crankshaft 33, which in turn affects the movement frequency of the piston column 321 and the boosting effect.

[0046] The first connecting rod 35 connects the secondary shaft of the crankshaft 33 with the second connecting rod 36 and the action rod 37, transmits the rotary motion of the crankshaft 33 to the subsequent components, drives the second connecting rod 36 and the action rod 37 to move, that is, converts the circular motion of the crankshaft 33 into the swing of the action rod 37 and the linear motion of the piston column 321.

[0047] The second connecting rod 36 is connected with the first connecting rod 35 and the adjusting assembly 4, and moves under the driving of the first connecting rod 35 while its movement is controlled by the adjusting assembly 4, thereby affecting the movement of the action rod 37 and the piston column 321. By changing the movement state of the second connecting rod 36 through the adjusting assembly 4, the movement amplitude and frequency of the piston column 321 are adjusted, and flexible adjustment of the pressurization process is realized to adapt to different water pressure requirements.

[0048] The action rod 37 connects the second connecting rod 36 and the piston column 321, and transmits the movement of the second connecting rod 36 to the piston column 321 to push the piston column 321 to make lifting movement in the fixed cylinder 32, so as to ensure that the piston column 321 moves according to the predetermined movement track, effectively extrudes and pressurizes the water in the fixed cylinder 32 and the input pressurization assembly 3, and then converts mechanical movement into water pressure lifting, so that the water in the pressurization assembly 3 can be directly delivered to the pretreatment unit 5 through pressurization.

[0049] The piston column 321 makes lifting movement in the fixed cylinder 32, extrudes the air in the fixed cylinder 32, and then extrudes the water delivered to the pressurization assembly 3, so as to increase the pressure of the water and make the water obtain higher pressure energy.

[0050] The adjusting assembly 4 drives the second connecting rod 36, changes the movement parameters of the piston column 321 such as movement amplitude and frequency by adjusting the movement of the second connecting rod 36, thereby adjusts the pressurization degree of the pressurization assembly 3, so that the pressurization assembly 3 can flexibly adjust the pressurization effect according to actual requirements, improves the adaptability of the pressurization assembly 3 to different water pressure conditions, and ensures that the pretreatment unit 5 can be provided with water with appropriate pressure in various situations.

[0051] The pressurization assembly 3 realizes the function of pressurizing the tap water with insufficient pressure in the municipal pipe network 1 through the cooperative work of various components. When the water pressure in the municipal pipe network 1 is lower than the set value of the control assembly, the driving part 34 drives the crankshaft 33 to rotate, the crankshaft 33 converts the rotary motion into reciprocating linear motion of the piston column 321 in the fixed cylinder 32 through the connecting rod mechanism, and the piston column 321 extrudes the air and water in the fixed cylinder 32 to increase the pressure of the water. At the same time, the adjusting assembly 4 can adjust the pressurization process according to actual requirements to ensure that the output water pressure is stable and meets the requirements of the pretreatment unit 5. Overall, the pressurization assembly 3 effectively solves the problem that the pretreatment unit 5 cannot meet the water pressure requirement when the water pressure in the municipal pipe network 1 is insufficient, ensures the stable operation of the tap water pretreatment device and system, and improves the adaptability of the entire system to different water pressure conditions.

[0052] Further, the adjusting assembly 4 comprises a mounting frame 41 and a sliding frame 42, both of which are arranged on the side of the fixed cylinder 32, the mounting frame 41 is above the sliding frame 42, a rotating shaft 43 is rotatably arranged on the mounting frame 41, a first bevel gear 44 is sleeved on the rotating shaft 43, a second bevel gear 45 is meshingly connected with the first bevel gear 44, a follow-up shaft 46 is arranged on the center axis of the second bevel gear 45, a sliding block 47 is slidably arranged on the sliding frame 42, the follow-up shaft 46 moves in the sliding block 47, the follow-up shaft 46 and the sliding block 47 can be threadedly connected, the second connecting rod 36 is rotatably arranged on the sliding block 47, the follow-up shaft 46 is sleeved with an adapter 48, and the other end of the adapter 48 is rotatably sleeved on the rotating shaft 43. The mounting frame 41 provides support and mounting basis for the rotating shaft 43, so that the rotating shaft 43 can stably rotate.

[0053] The sliding frame 42 provides a specific sliding track for the sliding block 47, limits the movement path of the sliding block 47, so that the sliding block 47 can only slide along the direction of the sliding frame 42, thereby ensuring the accuracy and stability of the movement of the sliding block 47, so that the adjusting assembly 4 can accurately control the movement of the second connecting rod 36, thereby realizing accurate adjustment of the supercharging degree of the supercharging assembly 3.

[0054] The rotating shaft 43 transmits external rotary power to the first bevel gear 44, and the rotating shaft 43 can be rotated manually or by electricity, so as to drive the entire adjusting assembly 4 to work. In this application, a power source 411 is arranged on the mounting frame 41, and the output shaft of the power source 411 drives the rotating shaft 43 to rotate. The angle and speed of rotation of the rotating shaft 43 can directly affect the movement state of the subsequent components, thereby realizing flexible adjustment of the supercharging assembly 3.

[0055] The first bevel gear 44 is installed on the rotating shaft 43 and is meshed with the second bevel gear 45. The first bevel gear 44 transmits the rotary motion of the rotating shaft 43 to the second bevel gear 45 and changes the direction of motion, realizing power transmission. The second bevel gear 45 is meshed with the first bevel gear 44, the follow-up shaft 46 is sleeved with the second bevel gear 45, the second bevel gear 45 receives the power transmitted by the first bevel gear 44, drives the follow-up shaft 46 to rotate together, so that the follow-up shaft 46 can rotate according to the predetermined direction and speed, providing a power basis for the movement of the subsequent sliding block 47.

[0056] The follow-up shaft 46 rotates with the second bevel gear 45 on one hand and moves in the sliding block 47 on the other hand. The follow-up shaft 46 converts the rotary motion of the second bevel gear 45 into the sliding motion of the sliding block 47 in the sliding frame 42, realizes the conversion of the motion form, changes the position and angle of the second connecting rod 36, and realizes the adjustment of the supercharging assembly 3.

[0057] The slider 47 slides in the sliding frame 42 and is rotatably connected with the second connecting rod 36. The slider 47 transmits the movement of the follow-up shaft 46 to the second connecting rod 36, changes the position and angle of the second connecting rod 36 through its own sliding, and then affects the movement parameters such as the movement amplitude and frequency of the piston column 321 in the pressurizing assembly 3, so as to realize the accurate adjustment of the pressurizing degree of the pressurizing assembly 3.

[0058] The adapter 48 plays a role of connection and transition, ensures that the follow-up shaft 46 can be stably connected with the rotating shaft 43 during rotation, and allows the follow-up shaft 46 to move in the slider 47, so as to ensure the normal work of the adjusting assembly 4.

[0059] When it is necessary to change the pressurizing degree of the pressurizing assembly 3, the rotating shaft 43 is rotated, the first bevel gear 44 and the second bevel gear 45 are driven, the follow-up shaft 46 is rotated, the follow-up shaft 46 drives the slider 47 to slide in the sliding frame 42, the sliding of the slider 47 changes the position and angle of the second connecting rod 36, and then affects the movement amplitude and frequency of the piston column 321 in the pressurizing assembly 3, so as to finally realize the adjustment of the pressurizing degree of the pressurizing assembly 3. Through the adjusting assembly 4, the pressurizing degree of the pressurizing assembly 3 can be timely and accurately adjusted according to the change of the municipal pipe network 1 water pressure and the actual demand of the pretreatment unit 5 for the water pressure, so as to ensure that the pretreatment unit 5 can obtain a stable and appropriate pressure water source, improve the operation efficiency and stability of the entire system, reduce the waste of energy, and ensure the smooth progress of the tap water pretreatment work.

[0060] The sliding frame 42 is provided with an arc-shaped sliding groove 421, and the slider 47 is slidably arranged on the sliding groove 421. The arc-shaped sliding groove 421 limits the movement track of the slider 47, so that the slider 47 can only slide along the arc-shaped path. Compared with the linear sliding groove 421, the arc-shaped sliding groove 421 can guide the slider 47 to make a more complex movement path change, provide more possibilities for adjusting the movement of the second connecting rod 36, and meet the change of pressurization.

[0061] Specifically, the pressurizing assembly 3 includes a first conveying pipe 38, one end of the first conveying pipe 38 is connected with the water supply end, the other end is connected with the pretreatment unit 5, the fixed cylinder 32 is connected with a pressurizing pipe 39, and the output end of the pressurizing pipe 39 is in communication with the first conveying pipe 38. The first conveying pipe 38 serves as a main water conveying channel, is used for conveying tap water needing pressurization and conveying the pressurized tap water to the pretreatment unit 5, ensures the stable transmission of the tap water between the pressurizing assembly 3 and the pretreatment unit 5, and ensures the continuous water supply of the pretreatment unit 5. The two ends of the first conveying pipe 38 are connected with flanges and sealing elements, so as to ensure the sealing of the water flow, prevent the leakage phenomenon, and maintain the normal operation of the entire pretreatment system. The electromagnetic valves 61 are arranged at the two ends of the first conveying pipe 38. When the water pressure is insufficient, the valves of the first conveying pipe 38 are opened, and the pressurization effect is realized.

[0062] The pressurizing pipe 39 delivers the pressurized air and water in the fixed cylinder 32 to the first delivery pipe 38, so that the pressurized water can be mixed with the water from the municipal pipe network 1 (not pressurized) or directly delivered to the pretreatment unit 5, realizing the integration of the pressurized water and the overall water flow and ensuring that the pressurized water can smoothly enter the subsequent delivery link and provide the pretreatment unit 5 with a water source meeting the pressure requirement.

[0063] Reference Figure 1 , Figure 5 and Figure 6 When the water pressure detected by the pressure sensor is greater than the set value of the control assembly, the monitoring assembly 2 is enabled, which includes the second delivery pipe 21 connected at one end to the water supply end and at the other end to the pretreatment unit 5. The baffle 22 is hingedly arranged in the second delivery pipe 21 and is arranged with a gap between the baffle 22 and the inner wall of the second delivery pipe 21. The second delivery pipe 21 serves as a water flow channel, and when the water pressure of the municipal pipe network 1 meets the requirement, the water at the water supply end of the municipal pipe network 1 is delivered to the pretreatment unit 5 to provide a water source for the pretreatment link, and the water pressure of the municipal pipe network 1 can be directly utilized without the need for pressure relief and pressurization to the pretreatment unit 5, thereby reducing energy waste.

[0064] The baffle 22 can rotate under the action of the water flow, and the rotation of the baffle 22 adjusts the cross-sectional area through which the water flow passes, thereby buffering and adjusting the water flow speed and pressure to a certain extent. At the same time, when the water flow is abnormal, it can play a certain blocking effect to prevent the pretreatment unit 5 from being impacted by impurities or abnormal water flow.

[0065] The gap of the baffle 22 can ensure that even when the baffle 22 is in a closing trend, water flow can still pass through, avoiding complete blockage of the water flow and ensuring continuous water supply to the pretreatment unit 5. At the same time, when the water flow passes through the gap, it will generate a certain force on the baffle 22, allowing the baffle 22 to flexibly adjust the angle according to the water flow conditions.

[0066] The baffle 22 is provided with an angle sensor, which can accurately measure the rotation angle of the baffle 22 in real time and convert the angle information into an electrical signal. Through monitoring of the angle of the baffle 22, the size and direction change of the force of the water flow on the baffle 22 can be intuitively reflected, because the change in the angle of the baffle 22 is caused by the impact of the water flow. The angle data of the baffle 22 monitored is transmitted to the control assembly of the entire tap water pretreatment device, and the control assembly judges the changes in the pressure, flow, and other parameters of the water flow according to these data, and then makes corresponding decisions. When the angle sensor is not within the angle set range of the control assembly (i.e., the angle of the baffle 22 changes little), the water flow impact is small, and it is necessary to enter the first delivery pipe 38 again for further pressurization or enter the pretreatment unit 5 together with the pressurized water to better enter the pretreatment unit 5.

[0067] The second conveying pipe 21 is connected with a plurality of pipe fittings 6 with different diameters between the pretreatment unit 5, the pipe fittings 6 are provided with electromagnetic valves 61, and the angle sensor is electrically connected with the electromagnetic valves 61. The plurality of pipe fittings 6 with different diameters can provide a plurality of water flow channel selections to meet the requirements of different water flow and pressure, and the output end of the second conveying pipe 21 is provided with a water pressure sensor to detect the output water pressure of the second conveying pipe 21. Under different output water pressures and water use conditions, the water flow entering the pretreatment unit 5 can be flexibly adjusted by switching the pipe fittings 6 with different diameters, so as to ensure that the pretreatment unit 5 operates in the best working state. When the output water pressure of the municipal pipe network 1 is large, the pipe fitting 6 with a larger diameter can be selected to ensure that sufficient water enters the pretreatment unit 5; when the output water pressure is small, the pipe fitting 6 with a smaller diameter is selected to maintain a suitable water flow speed and pressure.

[0068] The electromagnetic valves 61 can quickly and accurately control the opening and closing of the corresponding pipe fittings 6 according to the signals transmitted by the angle sensor. When receiving a specific signal sent by the angle sensor, the electromagnetic valves 61 will open or close the pipe fittings 6 with different diameters according to the preset program, realize the switching of the water flow channel, realize the precise control of the water flow, cooperate with the angle sensor and the pipe fittings 6 with different diameters, and make the system can automatically adjust the water flow path and flow according to the real-time water flow condition.

[0069] The first conveying pipe 38 is also connected with a plurality of pipe fittings 6 with different diameters between the pretreatment unit 5, the pipe fittings 6 are provided with electromagnetic valves 61, and the plurality of pipe fittings 6 with different diameters can provide a plurality of water flow channel selections to meet the requirements of different water flow and pressure. Another pressure sensor and flow meter (not the same as the pressure sensor installed at the water supply end of the municipal pipe network 1) can be installed at the output end of the first conveying pipe 38. Under different water pressures and water use conditions, the water flow entering the pretreatment unit 5 can be flexibly adjusted by switching the pipe fittings 6 with different diameters according to the values of the corresponding pressure sensor and flow meter, so as to ensure that the pretreatment unit 5 operates in the best working state.

[0070] The first delivery pipe 38 is connected to the second delivery pipe 21, and when the water pressure of the municipal pipe network 1 is unstable, the water pressurized by the pressurizing assembly 3 can be integrated and adjusted with the water directly from the municipal pipe network 1 (through the second delivery pipe 21). When the water pressure is insufficient and the pressurizing assembly 3 is working, the pressurized water flows into the second delivery pipe 21 through the communication, and is mixed with the water directly supplied from the municipal pipe network 1, so as to ensure that the water pressure and flow rate of the water entering the pretreatment unit 5 are stable; when the water pressure is sufficient, the second delivery pipe 21 can directly deliver water, and if local water pressure fluctuates, the pressurizing assembly 3 can supplement pressurized water in time. When the water pressure of the second delivery pipe 21 is not very large, that is, the angle sensor detects a small value, the water can also be delivered to the first delivery pipe 38 for further pressurization or enter the pretreatment unit 5 together with the pressurized tap water. Regardless of the change of the water pressure of the municipal pipe network 1, the device can ensure that the pretreatment unit 5 has a stable water source supply.

[0071] The implementation process of the embodiment of the tap water pretreatment device is as follows:

[0072] Water pressure monitoring stage: the pressure sensor continuously monitors the water pressure of the water supply end of the municipal pipe network 1, and converts the water pressure signal into an electrical signal and transmits it to the control assembly in real time.

[0073] When the water pressure is sufficient: when the control assembly receives the pressure sensor signal showing that the water pressure is greater than the set value, the control monitoring assembly 2 opens the related components. At this time, the baffle 22 in the second delivery pipe 21 is opened to a certain angle under the action of the water flow (because the baffle 22 is gap-set with the second delivery pipe 21, even if the baffle 22 has a tendency to close, there is still water flow), and the water of the municipal pipe network 1 flows to the pretreatment unit 5 through the second delivery pipe 21. In this process, the angle sensor on the baffle 22 monitors the angle of the baffle 22 in real time, and transmits the data to the solenoid valve 61 electrically connected thereto. If the angle sensor detects that the angle of the baffle 22 is abnormal, it reflects that the water flow is abnormal, and the solenoid valve 61 can control the opening and closing of the different diameter pipe fittings 6 connected between the second delivery pipe 21 and the pretreatment unit 5 according to the preset program, so as to adjust the water flow speed and flow rate, and ensure that the water flow entering the pretreatment unit 5 is stable.

[0074] When the water pressure is insufficient: if the water pressure signal received by the control assembly is less than the set value, the booster assembly 3 is started. The driving member 34 drives the crankshaft 33 to rotate, and the crankshaft 33 converts the rotary motion into the lifting motion of the piston column 321 in the fixed cylinder 32 through the first connecting rod 35, the second connecting rod 36 and the action rod 37. The piston column 321 extrudes the air and water in the fixed cylinder 32, so that the pressure is increased. The water after pressure boosting enters the first conveying pipe 38 through the pressure boosting pipe 39. A pressure sensor is arranged at the output end of the first conveying pipe 38. The control assembly selects the on-off of the pipe fitting 6 with different diameters according to the real-time detection of the pressure sensor, adjusts the water flow speed and flow rate, and ensures the stability of the water flow entering the pretreatment unit 5. In this process, the adjusting assembly 4 can adjust the pressure boosting process. The rotating shaft 43 on the mounting bracket 41 is rotated, the first bevel gear 44 is rotated, the driven shaft 46 is rotated through the meshing with the second bevel gear 45. The driven shaft 46 moves in the sliding block 47 and drives the sliding block 47 to slide in the arc-shaped sliding groove 421. The sliding block 47 drives the second connecting rod 36 to move, thereby changing the movement amplitude and frequency of the piston column 321, and realizing the adjustment of the pressure boosting degree.

[0075] When the water pressure of the municipal pipe network 1 is unstable, the conveying end of the first conveying pipe 38 after pressure boosting is connected with the input end of the second conveying pipe 21, and the water after pressure boosting can be mixed with the water directly from the municipal pipe network 1, and finally enters the pretreatment unit 5, or the water pressure of the second conveying pipe 21 is not very large, that is, the detection value of the angle sensor is small, and the water can be conveyed to the first conveying pipe 38 for further pressure boosting or enter the pretreatment unit 5 together with the water after pressure boosting.

[0076] Pretreatment stage: whether the tap water directly flowing into the pretreatment unit 5 through the monitoring assembly 2 or the tap water after pressure boosting flowing into the pretreatment unit 5 through the pressure boosting assembly 3, the tap water is subjected to a series of pretreatment operations such as sedimentation, filtration and disinfection in the pretreatment unit 5, so as to remove impurities and microorganisms in the water, and make the water quality meet the subsequent use requirements.

[0077] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
