Description

Technical Field

[0001] The utility model relates to the technical field of water treatment systems, and in particular to an integrated intelligent water supply module for a medical central water supply system. Background Art

Among them, the post-treatment system consists of a water supply pump, a sterilizer, and pipe valves. There are generally the following problems: 1. The system components are not integrated and the on-site installation is complicated; 2. The pressure in the pipeline fluctuates dynamically when the terminal water consumption changes, resulting in insufficient or excessive water supply; 3. The failure of a single water supply pump interrupts the terminal water use; 4. It is impossible to read water quality information in real time; 5. The poor quality of the return water leads to substandard water supply, etc. Utility Model Content

[0003] The purpose of the utility model is to solve the deficiencies of the above-mentioned prior art and to provide an integrated intelligent water supply module for a medical central water supply system. The module adopts an integrated design to integrate a water pump, a sterilizer and related pipe valves in one module. The module is easy to install and can be expanded by directly increasing the number of modules when the water volume is increased. The module can be expanded conveniently and quickly. The dynamic balance between water supply and water use can be achieved by keeping the pressure constant, thus solving the problem of insufficient or excessive water supply caused by dynamic changes in terminal water consumption.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] An integrated intelligent water supply module for a medical central water supply system includes, in the direction of the main pipeline at the rear side of the water production main unit, a pure water tank in the machine room, a sterilizer, a parallel water supply pump A and a water supply pump B, a microporous filter, several water use points outside the machine room, and a three-way valve is provided on the main pipeline back to the machine room. A return pipeline is connected between the three-way valve and the pure water tank, and the three-way valve is connected to the raw water tank through a pipeline. An inlet valve is provided on the main pipeline in front of the pure water tank. The sterilizer, the parallel water supply pump A and the water supply pump B, and the microporous filter are installed together in an integrated mounting part to form an integrated module. The integrated module is easy to install and easy to expand, and the number of integrated modules can be selected according to the water consumption.

[0006] Preferably, the pure water tank is connected to a discharge pipe A, on which a butterfly valve A and an electric valve are provided in parallel.

[0007] Preferably, the sterilizer is an over-flow ultraviolet sterilizer.

[0008] Preferably, the water supply pump A and the water supply pump B are variable frequency water pumps. Dual variable frequency constant pressure water supply is adopted. When the terminal water consumption increases, the frequency is increased to increase the water pump speed accordingly. When the terminal water consumption decreases, the frequency is reduced and the water pump speed is reduced accordingly, so as to achieve a constant water supply pressure in the circulation pipeline and a dynamic balance between water supply and water use. When the water supply exceeds the standard for a short time and exceeds that of one water supply pump, pump A switches to industrial frequency operation and pump B starts variable frequency operation. When the water volume returns to normal, pump B automatically stops and pump A switches to variable frequency operation. At the same time, the dual pump design also ensures that one pump is still available after a single pump fails.

[0009] Preferably, the microporous filter and the main pipe on the rear side of the microporous filter are connected with a discharge pipe B, and a butterfly valve B is provided on the discharge pipe B.

[0010] Preferably, a butterfly valve C and a butterfly valve D are respectively provided at both ends of the main pipe within the range of the integrated mounting component.

[0011] Preferably, a butterfly valve E and a butterfly valve F are respectively provided on the main pipes on the front side of the water supply pump A and the water supply pump B, and a check valve A and a check valve B are respectively provided on the main pipes on the rear side.

[0012] Preferably, a conductivity meter A is provided on the main pipe at the rear side of the microporous filter, and a conductivity meter B is provided on the main pipe at the front side of the three-way valve. Real-time online monitoring of water quality is achieved to solve the problem of being unable to read water quality information immediately.

[0013] Preferably, a sampling valve is provided on the main pipe at the rear side of the conductivity meter A.

[0014] Preferably, a ball valve A is provided on the return water pipeline, a discharge pipe C is connected to the return water pipeline in front of the ball valve A, and a ball valve B is provided on the discharge pipe C.

[0015] The advantages of the utility model are: 1. System integrated design integrates the water pump, sterilizer and related pipe valve parts in one module, which is easy to install. When the user selects the equipment, the number of modules is selected according to the water consumption. When the water volume is increased, it can be achieved by directly increasing the number of modules, and the expansion is convenient and fast.

[0016] 2. Use dual-frequency constant pressure water supply to achieve a dynamic balance between water supply and water use through constant pressure, solve the problem of insufficient or excessive water supply caused by dynamic changes in terminal water consumption, increase stability, avoid downtime for maintenance, and solve the problem of terminal water use interruption due to failure of a single water supply pump.

[0017] 3. Add online water quality monitoring. The supply water conductivity and return water conductivity are integrated into the intelligent module to realize real-time online water quality monitoring and solve the problem of not being able to read water quality information immediately.

[0018] 4. Set different water quality standards for different departments. Under normal circumstances, the pure water in the circulation pipeline returns to the corresponding pure water tank. When the return water quality is lower than the standard value, the three-way valve is switched to make it flow back to the original water tank, thereby preventing the water quality from not meeting the standard due to poor return water quality.

[0019] 5. Use PLC and online instruments to control return water in real time, arrange pipeline disinfection in a timely and reasonable manner, ensure the water quality of terminal water supply, and solve the problem of substandard return water quality affecting water supply quality.

[0031] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0032] Embodiment 1: Figure 1As shown, an integrated intelligent water supply module of a medical central water supply system includes, in the direction of the main line 100 at the rear side of the water production host, a pure water tank 10 in the machine room, a sterilizer 20, a parallel water supply pump A30 and a water supply pump B40, a microporous filter 50, several water use points 60 outside the machine room, and a three-way valve 101 is provided on the main line 100 returning to the machine room, a return water pipeline 200 is connected between the three-way valve 101 and the pure water tank 10, and the three-way valve 101 is connected to the raw water tank through a pipeline, and a water inlet valve 111 is provided on the main line 100 at the front side of the pure water tank 10. In addition, the sterilizer 20, the parallel water supply pump A30 and the water supply pump B40, and the microporous filter 50 are installed together in the integrated mounting part 30 to form an integrated module.

[0033] Wherein, the sterilizer 20 is an over-flow ultraviolet sterilizer, and the water supply pump A30 and the water supply pump B40 are variable frequency water pumps.

[0034] Embodiment 2: Figure 1 As shown, on the basis of Example 1, the pure water tank 10 is connected to a discharge pipe A11, on which a butterfly valve A12 and an electric valve 13 are provided in parallel, the microporous filter 50 and the main pipeline 100 on the rear side of the microporous filter 50 are connected to a discharge pipe B51, on which a butterfly valve B52 is provided, the return water pipeline 200 is provided with a ball valve A201, and the return water pipeline 200 on the front side of the ball valve A201 is connected to a discharge pipe C202, on which a ball valve B203 is provided.

[0035] Embodiment 3: Figure 1 As shown, on the basis of Example 1 or Example 2, butterfly valves C102 and D103 are respectively provided at both ends of the main line 100 within the range of the integrated mounting component 30, butterfly valves E104 and F105 are respectively provided on the main line 100 in front of the water supply pump A30 and the water supply pump B40, and check valves A106 and B107 are respectively provided on the main line 100 on the rear side.

[0036] Embodiment 4: Figure 1 As shown, based on the first, second or third embodiment, a conductivity meter A108 is provided on the main line 100 at the rear side of the microporous filter 50, and a conductivity meter B109 is provided on the main line 100 at the front side of the three-way valve 101.

[0037] Wherein, a sampling valve 110 is provided on the main pipeline 100 at the rear side of the conductivity meter A108.

[0038] The specific working method is as follows: when the terminal water point 60 has a water demand, the PLC module built into the module reads the liquid level information of the pure water tank 10. When the pure water tank 10 is above the medium liquid level, the water supply pump A30 is turned on. At this time, the water quality of the water supply is monitored by the conductivity meter A108. If the water quality meets the standard, the water supply is normal. Otherwise, the electric valve 13 is opened to drain through the discharge pipe A11, and the water inlet valve 111 is opened according to the change of the liquid level, thereby turning on the front-end water production host. Pure water is supplied to the terminal water point 60 through the water supply pump A30. When the water volume at the water point 60 changes, the speed of the water supply pump A30 is adjusted by the frequency converter to achieve a constant pressure in the circulation pipeline, so that the water supply and water use reach a dynamic balance. When the water supply exceeds the standard for a short time and is greater than one water supply pump, the water supply pump A30 switches to the power frequency operation, and the water supply pump B40 starts the variable frequency operation. When the water volume returns to normal, the water supply pump B40 is automatically stopped, and the water supply pump A30 switches to the variable frequency operation. The pure water in the circulation pipeline reads the return water quality of the conductivity meter B109 through the PLC module. When the water quality meets the standard, the water in the circulation pipeline directly returns to the corresponding pure water tank 10. When the water quality does not meet the standard, it is switched to return to the original water tank through the three-way valve 101, which not only ensures the water quality of the water supply, but also avoids the waste of water resources caused by direct discharge. When the return water quality does not meet the standard for many consecutive days, the built-in remote module will send the return water quality failure to the designated recipient in the form of an alarm message, so as to facilitate the timely arrangement of pipeline disinfection.

[0039] The above description is only a specific embodiment of the present invention, but the structural features of the present invention are not limited thereto. The present invention can be used on similar products. Any changes or modifications made by any technician in the field of the present invention are covered by the patent scope of the present invention.
