Abstract
Description
Technical Field
[0001] This utility model relates to the field of etching experiment technology, specifically to a liquid water quality adjustment device for solid nuclear track etching experiments. Background Technology
[0002] Solid-state nuclear track detectors are a detection technique based on the radiation damage tracks created by high-energy particles in solid materials. When charged particles (such as alpha particles, protons, or heavy ions) pass through the detector material, they leave damage tracks in their path. These tracks can be magnified by chemical or physical etching methods to form observable holes or etching cones.
[0003] Solid-state nuclear track etching is a technique that amplifies damage tracks formed by high-energy particles in solid-state detector materials through chemical etching. In practice, the etching process is typically carried out in a heated water bath to ensure a stable temperature of the etching solution and thus consistent etching results. However, prolonged heating can cause water evaporation, altering the concentration of the etching solution and affecting the etching height, track clarity, and accuracy, leading to measurement errors. Therefore, in solid-state nuclear track etching experiments, it is usually necessary to periodically replenish water to strictly control the concentration of the etching solution and ensure consistent and accurate etching results. Existing methods for measuring etching solution concentration typically involve using a hydrometer to measure the density of water to determine whether replenishment is needed. However, traditional hydrometers are often too long, making measurement inconvenient and unsuitable for operation in high-temperature, highly alkaline, or confined spaces. Furthermore, manually measuring water density during experiments is inefficient and prone to measurement errors, leading to inaccurate results. Frequent water density measurements are necessary for replenishment, but this increases both the workload for operators and the complexity of the experiment. Utility Model Content
[0004] The purpose of this invention is to provide a liquid water quality adjustment device for solid nuclear track etching experiments that can accurately detect the concentration of etching solution, facilitate water replenishment, effectively improve experimental efficiency and stability, enhance experimental safety and convenience, and is easy to operate. This device aims to solve the technical problems of existing measurement methods, which are prone to measurement errors, resulting in inaccurate experimental results, cumbersome operation, and time and effort.
[0005] To solve the above technical problems, the solution adopted by this utility model is as follows:
[0006] A liquid water quality conditioning device for solid nuclear track etching experiments is installed at the top of an etching tank, the top of which is equipped with a tank cover. The device includes a measuring tank, a T-shaped bracket, a conductivity sensor, a tank fixing plate, a water supply pipe, and a water extraction pipe. The measuring tank is installed above the middle of the tank fixing plate. The tank fixing plate is installed on one side of the tank cover at the top of the etching tank. The T-shaped bracket is connected to the top of the measuring tank, with its lower end extending into the measuring tank. The conductivity sensor is fixedly installed inside the lower end of the T-shaped bracket. One end of the water supply pipe is connected to a water source, and the other end extends into the etching tank. One end of the water extraction pipe passes through the tank fixing plate and extends into the etching tank, while the other end is connected to the measuring tank. After the measuring water tank is installed on the water tank fixing plate, it is sealed together with the water tank cover to cover the etching water tank. The water in the etching water tank is pumped out through the water pipe. The conductivity of the water sample is measured by the conductivity sensor inside the "T"-shaped fixing frame. The detected conductivity is compared with the conductivity at the beginning of the experiment to calculate the amount of pure water that needs to be added. The water supply pipe is turned on to add water to the etching water tank to ensure the concentration of the etching solution and to ensure the normal operation of the experiment. The whole system is powered by an external power supply.
[0007] Furthermore, the measuring water tank has five openings, three of which are installed side-by-side on the upper side of one side of the measuring water tank, and the remaining two openings are installed on the upper middle and lower parts of the other side of the measuring water tank, respectively. Each opening is equipped with a matching flat straight-through head. Three water suction pipes are provided, one end of which is connected to each of the three openings, and the other end extends into the etching water tank. The three water suction pipes extend into the etching water tank to different depths. One end of the water replenishment pipe is connected to the upper middle and lower openings on the other side of the measuring water tank. Water samples are extracted from three detection points through the three water pipes extending to different depths in the etching water tank. Each extraction of water samples from the three detection points constitutes one cycle. The conductivity values of the three water samples are compared. The cycle continues until the measured values of the three water sample detection points are consistent. Comparing the values at the beginning of the experiment, the required amount of pure water is added through the water replenishment pipe to adjust the concentration of the etching solution. The flat straight-through head ensures that the pipes are connected to the holes in the measuring water tank, ensuring overall sealing.
[0008] Furthermore, the water supply pipe includes an inlet pipe, an overflow pipe, a drain pipe, a filling pipe, and a four-way pipe; one end of the inlet pipe is connected to an external water source; one end of the overflow pipe and the drain pipe are respectively connected to the flat straight-through head above and below the measuring water tank; the other ends of the inlet pipe, overflow pipe, and drain pipe are connected to the four-way pipe; one end of the filling pipe is connected to the four-way pipe, and the other end passes through the water tank fixing plate and extends into the etching water tank; the filling pipe is connected to an external water source through the four-way pipe and the inlet pipe. The measuring water tank discharges excess water sample through the overflow pipe, and the drain pipe can discharge all water sample after the water sample testing of the measuring water tank is completed. The inlet pipe is connected to an external water source, and the water from the inlet pipe, overflow pipe, and drain pipe is collected through the four-way pipe and transported to the filling pipe, circulating back into the etching water tank.
[0009] Furthermore, the etching tank is equipped with magnetically attached water pipe holders; four water pipe holders are provided, each connected to one of the three water pumping pipes and one water filling pipe. The water pumping pipes can be firmly attached to the tank wall of the etching tank via the water pipe holders, and the position and depth of the water sample taken from the detection point can be adjusted at will, making the whole process convenient for installation and disassembly.
[0010] Furthermore, the water tank fixing plate is equipped with a fixing box; the fixing box is equipped with four electric water pumps; the electric water pumps are respectively installed in the middle of the three water suction pipes and the water inlet pipe; a miniature water pump is installed at the connection end of the drain pipe and the measuring water tank. The electric water pumps are fixed in place, allowing for convenient extraction of etching solution from the etching water tank into the measuring water tank, and can accurately deliver water to the etching water tank for replenishment. The miniature water pump is installed at the connection end of the drain pipe and the measuring water tank, enabling precise drainage of the etching solution. The electric water pumps and the miniature water pump are intelligently controlled by an external controller, facilitating the measurement of etching solution and water replenishment.
[0011] All water pipes are flexible hoses.
[0012] The working principle of this utility model is as follows:
[0013] In operation, an electric water pump draws water samples from one detection point into a measuring tank. Excess water overflows from the overflow pipe and circulates back into the etching tank. After sampling, the conductivity of the water sample is detected by a conductivity sensor. After detection, a miniature water pump drains the water sample from the measuring tank. After emptying the measuring tank, the miniature water pump is turned off. The electric water pumps at three different depths are used to draw water samples from the detection points for testing. When the measured values of the three detection points are consistent, the obtained values are compared with the conductivity values of the water samples at the beginning of the experiment. The required amount of pure water is calculated, and the electric water pump in the inlet pipe is turned on to draw external water to the water supply pipe to add water and adjust the concentration of the etching solution. When the measured data are inconsistent, the etching solution in the etching tank is allowed to settle before sampling and measurement is repeated until the measured values of the three water sample points are consistent. The water supply pipe guides the water samples overflowing from the overflow pipe, the water samples discharged from the drain pipe, and the water added from the inlet pipe into the etching solution in the etching tank.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. This utility model uses a water pipe to draw the etching solution into a measuring tank. The conductivity sensor inside the measuring tank can detect the conductivity of the etching solution in the etching tank in real time. By comparing the conductivity at the beginning of the experiment, the required amount of water can be accurately calculated to ensure the stability of the etching solution concentration in the etching tank, thereby ensuring the accuracy of the etching experiment. The overall operation is convenient.
[0016] 2. This utility model uses multiple different water pipes to extract etching solution at different depth detection points, which can comprehensively detect the concentration of etching solution. Combined with the operation of electric water pump and micro water pump, the etching solution can be accurately extracted for detection. At the same time, it is convenient and accurate to replenish the etching solution, saving time and effort, effectively reducing the error of manual detection, and improving the efficiency and stability of the experiment.
