Description

Technical Field

[0001] The utility model relates to the technical field of chemical transfer equipment, in particular to chemical transfer equipment capable of automatically adjusting pH. Background Art

[0002] In modern chemical equipment, transfer tanks are a type of equipment that is often used to prepare sulfuric acid. The diluted concentrated sulfuric acid needs to be mixed in the transfer tank before being discharged. Due to the small size of the transfer tank, the liquid level in the transfer tank needs to be controlled. If the transfer tank is too full, the acid will overflow and endanger the environment; emptying the transfer tank will cause the acid discharge pump to run idle, causing equipment damage; and since a large amount of heat will be generated during the dilution of concentrated sulfuric acid, the pH value of the transfer equipment needs to be monitored and adjusted in real time to avoid dilution too quickly, causing the dilution liquid to boil and causing equipment damage. Existing transfer equipment usually uses pH detection equipment to detect the internal pH, but due to the exothermic effect during the dilution of sulfuric acid, it is easy to cause errors in the detection results of the pH detection equipment. In view of this, in-depth research was conducted on the above-mentioned issues, resulting in this case. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides an implementation scheme: in the application process of the transfer tank 1, in order to avoid the boiling of sulfuric acid caused by the excessive dilution rate of sulfuric acid, thereby endangering the safety of equipment and personnel, the transfer tank 1 at this stage needs to monitor the pH in the transfer tank 1 in addition to the liquid level. The present application discloses a chemical transfer equipment that can automatically adjust the pH. The equipment is based on the transfer tank 1. The transfer tank 1 is a kettle body with a cavity structure. The top and bottom of the transfer tank 1 are respectively provided with a feeding port 2 and a feeding port 3. The feed port 2 is connected to a feed pipe through a joint, and additives are added into the transfer tank 1 through the feed pipe. The feed port 3 is connected to an acid discharge pump 4 through a feed pipe for discharging diluted sulfuric acid. The transfer tank 1 is provided with a concentrated sulfuric acid feeding pipe 5, and concentrated sulfuric acid is injected into the transfer tank 1 through the concentrated sulfuric acid feeding pipe 5. Dilution water is injected through a water supply pipe 6 to complete the dilution of the concentrated sulfuric acid. A pair of control valves 7 are respectively connected to the concentrated sulfuric acid feeding pipe 5 and the water supply pipe 6. The control valve 7 is electrically connected to the detection device to control the feed rates of the two.

[0022] According to the instruction manual Figure 1-3 It can be seen that an insertion slot is provided on the top surface of the transfer tank 1, and a limit seat 8 is inserted in the insertion slot. The insertion slot is used to limit the limit seat 8 to fix the posture of the detection rod 9. The detection rod 9 is used to extend the PH detection probe 10 into the mixed liquid. The bottom end of the detection rod 9 is provided with a PH detection probe 10. The main body of the PH detection probe 10 is wrapped at the bottom of the detection rod 9, and only the head end is exposed to the outside. The head end of the PH detection probe 10 contacts the mixed liquid to monitor the PH value of the mixed liquid in real time. At the same time, a heat exchange cooling jacket groove 13 is wrapped on the outside of the PH detection probe 10. Water is supplied to the heat exchange cooling jacket groove 13 through the cooling water inlet pipe 11. The running water is used to absorb the heat released by the PH detection probe 10 due to the dilution of concentrated sulfuric acid, and then discharged from the cooling water outlet pipe 12, so as to keep the PH detection probe 10 working in a reasonable temperature range.

[0023] As a preferred solution, further, water inlet joints and water outlet joints are provided at the ends of the cooling water inlet pipe 11 and the cooling water outlet pipe 12 to facilitate connection with the external water supply pipe 6 .

[0025] As a preferred solution, further, a plurality of heat exchange fins 14 are arranged in a circular array outside the main body of the PH detection probe 10 , and the heat exchange cooling sleeve groove 13 is sleeved on the heat exchange fins 14 to improve the heat exchange efficiency of the PH detection probe 10 .

[0026] As a preferred solution, further, the limit seat 8 is a plate with a partially conical structure of a polygonal cross-section, and the insertion slot is structurally matched with the limit seat 8. Through the structural matching of the insertion slot and the limit seat 8, the axial limitation of the limit seat 8 is achieved to prevent the detection rod 9 from rolling.

[0027] As a preferred solution, further, a transmission connection seat 15 is provided on the limit seat 8 and is connected to the detection rod 9 for receiving the detection data of the pH detection probe 10.

[0028] From the above, it can be generally known that the chemical transfer equipment that can automatically adjust the pH value arranges an inserted pH detection probe 10 at the top of the transfer tank 1, uses the pH detection probe 10 to detect the pH of the mixed liquid in the transfer tank 1, and adjusts the feed amount of concentrated sulfuric acid and the flow rate of dilution water according to the pH value. At the same time, a high-efficiency heat exchange cooling device is wrapped outside the pH probe to take away the heat generated by the dilution of concentrated sulfuric acid, so that the pH detection probe 10 works in a reasonable temperature range.
