Abstract
Description
Technical Field
[0001] This utility model relates to the field of purified water tank overflow prevention technology, specifically a purified water tank with overflow prevention function. Background Technology
[0002] A purified water tank is a specialized container used to store and maintain high-purity water. Its core function is to effectively prevent the growth of microorganisms, particulate matter contamination, and ion precipitation through a sealed structure, inert materials such as 316L stainless steel or anti-corrosion coating, and a matching disinfection system such as ultraviolet sterilization, ozone sterilization, or circulating filtration device. This ensures that the water quality during storage meets the ultrapure water standard with a resistivity ≥18.2MΩ·cm. The purified water tank is a key piece of equipment in a pure water preparation system to ensure the quality of the final water.
[0003] In existing technologies, purified water tanks lack active overflow prevention functions, which makes it easy for external contaminants such as microorganisms, particulate matter, or chemicals to enter the tank back through the overflow channel when the purified water tank overflows, damaging the cleanliness of ultrapure water. This can easily lead to product defects, especially in pharmaceutical or electronics manufacturing. At the same time, unrecovered overflow water will cause high-cost waste of purified water and increase water production energy consumption. Utility Model Content
[0004] The purpose of this utility model is to provide a purified water tank with an anti-overflow function to solve the problems mentioned in the background art and overcome its technical defects.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a purified water tank with anti-overflow function, including a tank cover, a corrugated tank body and an anti-overflow component. The tank cover is movably connected to the corrugated tank body. The anti-overflow component includes an anti-overflow plate, a guide rod and a graduated tube. One end of the guide rod is fixedly connected to the anti-overflow plate, and the other end of the guide rod extends out and to the outside of the tank cover. One end of the graduated tube is fixedly connected to the anti-overflow plate, and the graduated tube is used for the floating range detection of the anti-overflow plate.
[0006] As a further embodiment of this utility model: a purified water tank with an anti-overflow function also includes an inlet pipe, which includes a straight pipe, a clamp pipe and an inlet. One end of the clamp pipe is fixedly connected to the inlet, and the other end of the clamp pipe is fixedly connected to the straight pipe. The straight pipe extends through the anti-overflow plate to the inner bottom of the tank cover, and the inlet extends to the outside of the tank cover.
[0007] As a further embodiment of this utility model: a purified water tank with an anti-overflow function, wherein a mating port is fixedly connected to one side of the tank cover, and the inlet is fixedly connected to the mating port.
[0008] As a further improvement of this utility model: a purified water tank with an anti-overflow function also includes a water seal, which is disposed in the interlayer between the inlet and the mating port and serves as a sealing device between the inlet and the mating port.
[0009] As a further improvement of this utility model: a purified water tank with an anti-overflow function, wherein a screw hole is fixedly connected to one side of the tank cover, and the scale cap is screwed into the screw hole.
[0010] As a further improvement of this utility model: a purified water tank with an anti-overflow function, wherein the connection between the guide rod and the tank cover is polished.
[0011] As a further improvement of this utility model: a purified water tank with an anti-overflow function, wherein the outer periphery of the graduated tube and the contact area between the graduated tube and the graduated cover are polished.
[0012] As a further improvement of this utility model: a purified water tank with an anti-overflow function, wherein the distance between the straight pipe and the bottom wall of the corrugated tank body is 1-1.5cm.
[0013] Compared with the prior art, the beneficial effects of this utility model include:
[0014] Because the lid is movably connected to the corrugated box body, one end of the guide rod is fixedly connected to the anti-overflow plate, and the other end of the guide rod extends out to the outside of the lid. One end of the scale tube is fixedly connected to the anti-overflow plate, and the scale tube is used for the floating range detection of the anti-overflow plate. Therefore, when purified water is injected into the corrugated box body through the water inlet pipe, the liquid level will lift the anti-overflow component upward. Since the lid is a round lid structure, the anti-overflow component will stop after contacting the bottom of the lid, which can prevent purified water from overflowing from the fitting port.
[0015] Because one end of the clamp is fixedly connected to the inlet and the other end is fixedly connected to the straight pipe, the straight pipe extends through the overflow plate to the inner bottom of the box cover, the inlet extends to the outside of the box cover, and a mating port is fixedly connected to one side of the box cover. The inlet is fixedly connected to the mating port, and the water seal is set in the interlayer between the inlet and the mating port to provide a seal between the inlet and the mating port. Therefore, purified water is introduced into the interior of the corrugated box from the inner bottom of the corrugated box, so that the purified water will not splash or cause noise during the filling process.
[0016] Since a screw thread is fixedly connected to one side of the box cover, the scale cap is screwed into the screw thread, and one end of the scale tube is fixedly connected to the anti-overflow plate. The scale tube is used for the floating range detection of the anti-overflow plate. Therefore, the scale tube can be removed after it is not in use, and the corrugated box can be covered with the scale cap with a small hole to reduce the loss of purified water.
