Description

A highly reliable automatic water storage device for water production equipment for hemodialysis

technical field

The utility model relates to a water storage system, in particular to an automatic water storage device for highly reliable hemodialysis water making equipment.

Background technique

The water making equipment for hemodialysis is a water treatment equipment specially required for hemodialysis. Patients may be exposed to more than 300L of water per week through the hemodialyzer or the semipermeable membrane of the hemodialysis filter. While a healthy person rarely consumes more than 12 liters of water per week, the amount of contact with water increases nearly 30 times. Therefore, water quality should be controlled and monitored to avoid excess of known or estimated harmful substances. The water used to prepare the dialysate is usually treated to a certain extent, and the water quality meets the specified requirements. The equipment performance of the water treatment system depends on the water quality of the raw water and the function of the whole system, to see whether it can prepare and continuously produce qualified treated water.

Under the existing technical conditions, the existing water-making equipment for hemodialysis pumps water into the water tank through a water pump. This method requires someone to check the amount of water in the water tank to determine whether water storage is required. It is necessary to manually turn on the water pump. If the size of the water tank is too small and the water storage capacity is not large, it may cause too many pumping times and increase the workload; Almost full. When running into a sudden emergency and causing the water storage device to be unavailable, the entire system will stop running or cause unnecessary troubles because the water storage device cannot be used.

Utility model content

The purpose of this utility model is to overcome the shortcomings of the prior art, and to provide a highly reliable automatic water storage device for hemodialysis water production equipment with simple structure, high efficiency and water saving. The signal detected by the water level sensor controls the main control solenoid valve and the water pump to open and close, so as to achieve the function of automatic water storage, and can control the opening of the water inlet pipeline through the backup control valve in the case of failure of the main control solenoid valve or controller And close, can avoid the situation that the water in the storage tank is short of water or the water overflows.

The purpose of this utility model is achieved through the following technical solutions: a highly reliable automatic water storage device for hemodialysis water-making equipment, which includes a water storage tank, a water inlet pipeline, a water outlet pipeline, an overflow pipeline and a controller. A water pump and a main control solenoid valve are arranged in turn on the water inlet pipeline, and a backup control valve is connected in parallel to the side of the main control solenoid valve. A water outlet control valve and a booster pump are installed on the road, the outlet pipeline is connected with the filter, the inlet of the water inlet pipeline is set above the water storage tank, the outlet of the water outlet pipeline is set on the lower side of the water storage tank, and the overflow pipeline is installed on the water storage tank The upper part of the water storage tank is provided with a high water level sensor and a low water level sensor, and the high water level sensor, the low water level sensor, the water pump, the booster pump and the main control solenoid valve are all electrically connected to the controller.

The backup control valve is a manual valve.

The inlet of the overflow pipeline is higher than the position of the sensor.

The utility model has the following advantages: the utility model can feed back the liquid level signal detected by the liquid level sensor to the controller, and control the opening and closing of the main control solenoid valve through the controller to realize pumping and stop pumping. Sensor detection can automatically respond in time and quickly when the liquid level is too high or too low. This device has a simple structure and does not require personnel to control the water pump, saving labor. The control valve connects the water pipe to the pipeline so as to store water, and ensures that the liquid level in the water storage tank will not be higher than the mouth of the overflow pipeline.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described, and the protection scope of the utility model is not limited to the following:

Fig. 1 is an automatic water storage device for a highly reliable hemodialysis water-making equipment, which includes a water storage tank 8, a water inlet pipeline 7, a water outlet pipeline 9, an overflow pipeline 13 and a controller 19, and the water inlet pipeline 7 is provided with a water pump 2 and a main control solenoid valve 3 in sequence, and a backup control valve 4 is connected in parallel to the side of the main control solenoid valve 3. In this embodiment, the backup control valve 4 is a manual valve, and the two sides of the backup control valve 4 The two ends are connected with the water inlet pipelines 7 at both ends of the main control solenoid valve 3 respectively, the water outlet pipeline 9 is provided with a water outlet control valve 10 and a booster pump 11, the water outlet pipeline 9 communicates with the filter 12, and the water inlet pipeline 7 The inlet of the water storage tank 8 is arranged on the top of the water storage tank 8, the outlet of the water outlet pipeline 9 is arranged on the lower side of the water storage tank 8, and the overflow pipeline 13 is installed on the top of the water storage tank 8. In this embodiment, the overflow pipeline 13 The inlet is higher than the position of the sensor 5. The water storage tank 8 is provided with a high water level sensor 5 and a low water level sensor 6. The high water level sensor 5, the low water level sensor 6, the water pump 2, the booster pump 11 and the main control solenoid valve 3 are all connected to the control valve. Device 19 is electrically connected,.

The working process of the present utility model is as follows: when water is stored in the water storage tank 8, and the height of the liquid level is equal to the position where the high water level sensor 5 is located, the high water level sensor 5, the water pump 2 and the main control solenoid valve 3 are all connected with the controller 19 The electricity is disconnected and is in a working state; when the liquid level is lower than the position of the high water level sensor 5, the high water level sensor 5, the water pump 2 and the main control solenoid valve 3 are all electrically connected with the controller 19 and are in a working state, and the water storage tank 8 Realize the function of automatic water storage; when the liquid level is equal to the position where the low water level sensor 6 is located, the booster pump 11 is electrically disconnected from the controller 19 and stops working until the liquid level is higher than the position where the low water level sensor 6 is located , the booster pump 11 is then electrically communicated with the controller 19 .
