Description

Technical Field

[0001] The utility model relates to the technical field of water supply equipment, in particular to an energy-saving sterile water buffer water tank. Background Art

[0002] Sterile water refers to water that has been processed by physical methods such as steam method, UHT thermal method, ultraviolet sterilization method, etc. on water containing bacterial colonies to obtain water without bacteria. After killing the bacteria, sterile water can be obtained through filtration. The inorganic salts in the water will not decrease. It is widely used in various laboratories or food processing plants. Using sterile water in food processing in food processing plants can greatly reduce the probability of finished products being contaminated by bacteria and effectively ensure food safety and hygiene.

[0003] When using sterile water in the food processing process, in order to keep the supply pressure and flow rate of sterile water constant for convenient automated processing control, a buffer water tank needs to be set in the water supply pipeline. The sterile water is pumped into the buffer water tank by a water supply pump, and the sterile water in the buffer water tank is pumped out from the other end at a constant water pressure, effectively avoiding the water pressure fluctuation phenomenon caused by unstable water supply pipelines and when opening and closing valves, making the sterile water supply more stable.

[0004] Although the above-mentioned prior art can solve the corresponding technical problems, there are still certain defects: when the water level inside the existing buffer water tank is in a high position state, the water supply pump will still keep working and continuously pump the sterile water in the water pipe into the buffer water tank. However, continuously pumping sterile water when the water level in the buffer water tank is in a high position state will not bring a better effect on preventing water pressure fluctuation, thereby causing waste of electric energy and increasing the use cost. At the same time, continuously pumping water after the buffer water tank is filled with sterile water will also cause the pressure in the constant pressure water pipe to increase, resulting in the phenomenon that the pressure in the constant pressure water pipe is difficult to control. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an energy-saving sterile water buffer water tank with low power consumption and easy water pressure control in view of the defects and deficiencies of the prior art.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions: an energy-saving sterile water buffer water tank, including a water tank body and a water inlet pipe arranged on the side wall above the water tank body and communicating with the water tank body. A water outlet pipe communicating with the water tank body is also arranged at a position below the water inlet pipe on the side wall of the water tank body. A water supply pump is arranged on the water inlet pipe. A liquid level sensor is arranged inside the water tank body. The liquid level sensor is electrically connected to the water supply pump. The liquid level sensor monitors the liquid level in the inner cavity of the water tank body and transmits an electrical signal to stop the water supply pump when the liquid level reaches a certain height. A one-way water supply pipe connecting the water inlet pipe and the water outlet pipe is arranged between the water inlet pipe and the water outlet pipe.

[0007] Further improvement: A detachable top cover is provided at the top of the water tank body.

[0008] Further improvement: A telescopic support is provided at the bottom of the water tank body.

[0009] Further improvement: A water pressure sensor is embedded on the water outlet pipe, and the water pressure sensor is electrically connected to the water supply pump.

[0010] Further improvement: The one-way water supply pipe includes a connecting pipe disposed between the water inlet pipe and the water outlet pipe and connecting the water inlet pipe and the water outlet pipe, and a one-way valve disposed in the connecting pipe with an opening direction facing the water outlet pipe.

[0011] Further improvement: The one-way valve includes a groove pipe disposed in the connecting pipe and a closing block with an outer surface fitting to the inner wall of the groove pipe and capable of closing the groove pipe, and an elastic member is provided between the lower part of the closing block and the inner wall of the groove pipe.

[0012] Further improvement: The elastic member is a spring.

[0013] Further improvement: The elastic member includes a sliding pipe disposed on the inner wall of the groove pipe and a pressing column disposed below the closing block and slidably connected to the inner wall of the sliding pipe, and a compression spring is provided between the pressing column and the inner wall of the sliding pipe.

[0014] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows: The present utility model uses a liquid level sensor to sense the liquid level height in the water tank body, stops the water supply pump when the liquid level height is relatively high, avoids the waste of electric energy caused by the continuous operation of the water supply pump when the liquid level in the water tank body is relatively high, and at the same time avoids the excessive water pressure at the water outlet pipe that is difficult to control due to continuous pumping after the water tank body is filled with water.

[0018] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0019] See Figure 1-2 As shown, the technical solution adopted in this specific embodiment is as follows: An energy-saving sterile water buffer water tank includes a water tank body 1 and a water inlet pipe 2 provided on the side wall above the water tank body 1 and communicating with the water tank body 1. A water outlet pipe 4 communicating with the water tank body 1 is further provided at a position below the water inlet pipe 2 on the side wall of the water tank body 1. A water supply pump 3 is provided on the water inlet pipe 2. A liquid level sensor 5 is provided inside the water tank body 1. The liquid level sensor 5 is electrically connected to the water supply pump 3. The liquid level sensor 5 monitors the liquid level inside the water tank body 1 and transmits an electrical signal to stop the water supply pump 3 when the liquid level reaches a certain height. During use, the water inlet pipe 2 is connected to an external sterile water pipe, and the water supply pump 3 is used to pump sterile water into the water tank body 1 through the water inlet pipe 2. After it accumulates inside the water tank body 1, it can be pumped out from the water outlet pipe 4 at a constant pressure. When the water supply pump 3 pumps in a sufficient amount of sterile water and the sterile water level reaches a relatively high level, at this time, the liquid level sensor 5 detects the liquid level data. When the liquid level reaches the specified height, the water supply pump 3 can be stopped by the electrical signal output by the liquid level sensor 5, avoiding the waste of electric energy caused by the continuous operation of the water supply pump when the liquid level in the water tank body is relatively high, and at the same time avoiding the excessive pressure at the water outlet pipe caused by continuous pumping after the water tank body is filled with water and being difficult to control;

[0020] A detachable top cover 8 is provided on the top of the water tank body 1, which is beneficial for observing and cleaning the inside of the water tank body 1;

[0021] A telescopic support 9 is provided at the bottom of the water tank body 1, which is beneficial for adjusting the height of the water tank body 1 and making its applicability stronger;

[0022] A water pressure sensor 6 is embedded on the water outlet pipe 4. The water pressure sensor 6 is electrically connected to the water supply pump 3, which is beneficial for monitoring the water pressure at the water outlet pipe 4 and starting the water supply pump 3 to pressurize the water supply when the water pressure is too low. In this embodiment, if the water pressure at the water pressure sensor is lower than 1.8 Bar, an electrical signal is transmitted by the water pressure sensor 6 to the water supply pump 3 to pump water and pressurize;

[0023] A one-way water supply pipe 7 connecting the water inlet pipe 2 and the water outlet pipe 4 is provided between the water inlet pipe 2 and the water outlet pipe 4. The one-way water supply pipe 7 includes a connecting pipe 71 disposed between the water inlet pipe 2 and the water outlet pipe 4 and connecting the water inlet pipe 2 and the water outlet pipe 4, and a one-way valve disposed in the connecting pipe 71. The one-way valve includes a groove pipe 72 disposed in the connecting pipe 71 and a closing block 73 whose outer surface fits against the inner wall of the groove pipe 72 and can close the groove pipe 72. An elastic member is provided between the lower part of the closing block 73 and the inner wall of the groove pipe 72. When the terminal water consumption increases, resulting in a decrease in the pipeline pressure of the water outlet pipe 4, and the main water inlet pressure at the water inlet pipe 2 is greater than the constant pressure water supply pressure at the water outlet pipe 4, the closing block 73 of the one-way valve is pressed down, causing a gap between it and the inner wall of the groove pipe 72. Thus, the one-way valve is pushed open to enter the water replenishment state until the constant pressure water supply pressure at the water outlet pipe 4 is restored and the one-way valve shuts off.

[0024] The elastic member is a spring, or it can also be a sliding pipe 75 disposed on the inner wall of the groove pipe 72 and a pressing column 74 disposed below the closing block 73 and slidably connected to the inner wall of the sliding pipe 75. A compression spring 76 is provided between the pressing column 74 and the inner wall of the sliding pipe 75, which is beneficial to being compressed when the one-way valve is opened, and then quickly pushing up the closing block 73 to close the groove pipe 72 after the pressures at the water outlet pipe 4 and the water inlet pipe 2 are balanced. At the same time, it provides a certain upward elastic force, thereby achieving the effect of opening the one-way valve only when a specified pressure difference is reached.

[0025] The working principle of the present utility model: When the present utility model is in use, the water inlet pipe 2 is connected to an external sterile water pipe, and the water supply pump 3 is used to pump sterile water into the water tank body 1 through the water inlet pipe 2. After the sterile water accumulates in the water tank body 1, it can be pumped out from the water outlet pipe 4 at a constant pressure. When the water supply pump 3 pumps in a sufficient amount of sterile water and the water level of the sterile water reaches a relatively high level, at this time, the liquid level sensor 5 detects the liquid level data. When the liquid level reaches the specified height, the water supply pump 3 can be stopped by the electrical signal output by the liquid level sensor 5, avoiding the waste of electric energy caused by the continuous operation of the water supply pump when the liquid level in the water tank body is relatively high, and at the same time avoiding the excessive water pressure at the water outlet pipe that is difficult to control due to continuous pumping after the water tank body is filled with water.
