Description

Technical Field

[0002] In the chemical industry, it is usually necessary to measure the specific gravity of sulfuric acid in the acid tank to determine the reaction conditions. The current method for measuring the specific gravity of sulfuric acid is generally manual sampling and measurement, which is: manually use a sampling acid barrel to take acid from a high-temperature acid tank, wait for the sulfuric acid to cool naturally, then manually carry the sulfuric acid in the sampling acid barrel to a measuring cylinder and pour it into the measuring cylinder. After weighing with an electronic scale, manually pour the sulfuric acid in the measuring cylinder back into the sampling acid barrel, and then pour the sulfuric acid in the sampling acid barrel back into the acid tank.

[0003] However, high-temperature strong acid is very dangerous. In the process of manual acid extraction, transportation, acid pouring and recovery of sulfuric acid, improper operation can easily cause harm to the operators. At the same time, the high-temperature sulfuric acid takes a long time to cool naturally to room temperature, which will delay the measurement time of sulfuric acid. Manual acid pouring will cause the liquid level of sulfuric acid in the measuring cylinder to be out of control, thereby affecting the measurement accuracy of sulfuric acid specific gravity.

[0020] See also Figure 1 The utility model discloses an automatic device for measuring specific gravity of sulfuric acid, comprising an acid tank 1, a cooling tank 2, a measuring cylinder 3, an electronic scale 4 and a temporary storage tank 5, wherein the acid tank 1 is used to store high-temperature sulfuric acid, the bottom of the acid tank 1 is connected to the cooling tank 2 through a first pipeline 101, the cooling tank 2 is used to cool the sample sulfuric acid to be measured, the measuring cylinder 3 is used to load the sample sulfuric acid to be measured, the measuring cylinder 3 is placed on the electronic scale 4, and the cooling tank 2 is arranged at one end of the measuring cylinder 3 away from the electronic scale 4.

[0021] Specifically, the cooling tank 2 includes a tank body 21, a cooling pipe 22 arranged inside the tank body 21, and a water inlet pipe 23 and a water outlet pipe 24 connected to the tank body 21. In the present embodiment, the water inlet pipe 23 is connected to the top of the tank body 21, the water outlet pipe 24 is connected to the bottom of the tank body 21 and is arranged on the same side as the water inlet pipe 23. The water inlet pipe 23 is used to replenish cooling water into the tank body 21 in real time, and the water outlet pipe 24 is used to discharge the cooling water in the tank body 21 in real time. The coordinated operation of the water inlet pipe 23 and the water outlet pipe 24 realizes the real-time replenishment of cooling water in the tank body 21, thereby ensuring the cooling effect of the cooling tank 2 on the sample sulfuric acid to be tested.

[0022] Furthermore, the liquid inlet of the cooling pipe 22 is arranged at the top of the tank body 21 and communicated with the first pipeline 101, and the liquid outlet of the cooling pipe 22 passes through the bottom of the tank body 21 and is located inside the mouth of the measuring cylinder 3. In order to improve the cooling effect of the cooling tank 2 on the sample sulfuric acid to be tested, the cooling pipe 22 in this embodiment is an S-shaped flow channel, and the S-shaped flow channel is used to increase the contact time between the sample sulfuric acid to be tested and the cooling water in the tank body 21, so as to quickly achieve the cooling effect.

[0023] Further, the first pipeline 101 is provided with a first valve 6, and the first valve 6 is used to control the conduction and closing of the first pipeline 101. The measuring cylinder 3 is provided with a liquid level controller 7 at one end near the cylinder mouth, and the liquid level controller 7 is connected to the first valve 6 to control the closing of the first valve 6. The measuring cylinder 3 is connected to the temporary storage tank 5 through the second pipeline 102, and the second pipeline 102 is provided with a second valve 8, and the second valve 8 is used to control the conduction and closing of the second pipeline 102. In this embodiment, the bottom end of the measuring cylinder 3 is connected to one end of the second pipeline 102, and the other end of the second pipeline 102 is connected to the top of the temporary storage tank 5.

It should be noted that the first valve 6 and the second valve 8 are both pneumatic valves.

[0024] In actual use, the use principle of the automatic sulfuric acid specific gravity measuring device of the utility model is as follows: high-temperature sulfuric acid with a temperature of 120°-140° is stored in the acid tank 1. When the specific gravity of the high-temperature sulfuric acid in the acid tank 1 needs to be measured, the first valve 6 is opened, and the high-temperature sulfuric acid in the acid tank 1 enters the cooling tank 2 through the first pipeline 101 for cooling. Specifically, the high-temperature sulfuric acid enters the cooling pipeline 22 through the first pipeline 101. Since the cooling pipeline 22 is surrounded by cooling water in the tank body 21, the temperature of the high-temperature sulfuric acid flowing in the S-shaped cooling pipeline 22 will gradually decrease, and finally flow into the measuring cylinder 3 from the liquid outlet of the cooling pipeline 22 at a suitable temperature. When the sample sulfuric acid in the measuring cylinder 3 reaches the preset liquid level, the liquid level controller 7 sends a closing signal to the first valve 6, and the first valve 6 will automatically close to achieve the closing of the first pipeline 101. The electronic scale 4 weighs the sample sulfuric acid in the measuring cylinder 3. When the electronic scale 4 finishes weighing, the second valve 102 is opened, and the sample sulfuric acid in the measuring cylinder 3 flows into the temporary storage tank 5 through the second pipeline 102 for storage. It should be noted that the high-temperature sulfuric acid in the acid tank 1 is discharged into the temporary storage tank 5 through the third pipeline 103 for cooling. When the sulfuric acid in the temporary storage tank 5 is cooled to below 40°, it will enter the corresponding facility through the drain pipe 104 for use.

[0025] In summary, the automatic sulfuric acid specific gravity measuring device of the utility model has a simple structure and is easy to operate. It can realize the automatic measurement of sulfuric acid specific gravity without manual operation. The whole process is safe and reliable, and the measurement efficiency is high. By setting a cooling tank between the acid tank and the measuring cylinder, the sulfuric acid is quickly cooled, which greatly saves the cooling time of the sulfuric acid sample to be tested and improves the machine utilization rate. Furthermore, by setting the first valve and the liquid level control valve, the precise control of the sulfuric acid sample to be tested in the measuring cylinder is realized, which greatly improves the accuracy of the measurement.
