Description
Technical field
The utility model relates to a kind of phosphoric acid storage tank device, especially a kind of phosphoric acid storage tank crystallization prevention device.
Background technology
The phosphoric acid of concentration 85% produces crystallization easily under consecutive low temperature, bring inconvenience to production.
The utility model content
The purpose of this utility model provides a kind of phosphoric acid storage tank crystallization prevention device simple in structure, easy to use.
Realize the phosphoric acid storage tank crystallization prevention device of the utility model purpose, comprise the electrical power control cabinet with coolant-temperature switch, be positioned at the thermal detector on the storage tank; Described storage tank below is connected with pipe type heating device, and the other end of described heating arrangement is connected to the top of storage tank by counter flow pipe; Described counter flow pipe is provided with measuring pump; On the described counter flow pipe, the both sides that are positioned at measuring pump are respectively equipped with feed pipe and discharge nozzle; Described thermal detector, measuring pump and heating arrangement link to each other with electrical power control cabinet respectively.
Described heating arrangement comprises high temperature resistant stainless steel pipe, high temperature resistance silk, crystal magnesium oxide powder and the high-temperature resistant shell that sets gradually from inside to outside.
Described feed pipe is positioned at the below of measuring pump, and discharge pipe is positioned at the top of measuring pump.
The beneficial effects of the utility model are as follows: phosphoric acid storage tank crystallization prevention device of the present utility model, by storage tank being carried out the controlled circulation heating, reach the purpose that prevents the phosphoric acid crystallization, and it is simple in structure and easy to use.
Description of drawings
Fig. 1 is the structural representation of phosphoric acid storage tank crystallization prevention device of the present utility model.
The specific embodiment
Embodiment of the present utility model is as follows: as shown in Figure 1, phosphoric acid storage tank crystallization prevention device of the present utility model comprises the electrical power control cabinet 11 with coolant-temperature switch 10, is positioned at the thermal detector 2 on the storage tank 1; Described storage tank 1 below is connected with pipe type heating device 4, and the other end of described heating arrangement 4 is connected to the top of storage tank 1 by counter flow pipe 15; Described counter flow pipe 15 is provided with measuring pump 13; On the described counter flow pipe 15, the both sides that are positioned at measuring pump 13 are respectively equipped with feed pipe 9 and discharge nozzle 14; Described thermal detector 2, measuring pump 13 and heating arrangement 4 link to each other with electrical power control cabinet 11 respectively.
Described heating arrangement 4 comprises high temperature resistant stainless steel pipe, high temperature resistance silk, crystal magnesium oxide powder and the high-temperature resistant shell that sets gradually from inside to outside.
Described feed pipe 9 is positioned at the below of measuring pump 13, and discharge nozzle 14 is positioned at the top of measuring pump 13.
The principle of work of phosphoric acid storage tank crystallization prevention device of the present utility model is as follows: the closed temperature that coolant-temperature switch 10 is set; When the temperature that thermal detector 2 detects was lower than 25 degrees centigrade, coolant-temperature switch 10 made its work by the power supply of electrical power control cabinet 11 connection heating arrangements 4 and measuring pump 13; When the temperature that thermal detector 2 detects was higher than 60 degrees centigrade, coolant-temperature switch 10 was closed heating arrangement 4 and measuring pump 13 power supplys by electrical power control cabinet 11, and it is quit work.
After heating arrangement 4 and measuring pump 13 start, phosphoric acid solution in the storage tank 1 enters the pipeline of heating arrangement 4 inside and accepts heating, and is back to storage tank 1 by counter flow pipe 15, under the effect of Heating Cyclic, can control the temperature of storage tank 1 inner phosphoric acid solution, reach the purpose that prevents the phosphoric acid crystallization.
Be respectively arranged with feed pipe 9 and discharge nozzle 14 in the import and export both sides of measuring pump 13, in the local time of need to being transported to other from storage tank 1 inner extraction phosphoric acid, close feed pipe 9 and counter flow pipe 15, start measuring pump 13 and extract phosphoric acid solutions; When needs carry phosphoric acid to enter storage tank 1 storage from the outside, close pipeline and the discharge nozzle 14 of heating arrangement 4, start measuring pump 13 and carry phosphoric acid solution to storage tank 1.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineering staff in this area make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
