7. The method for using the apparatus for synthesizing 2-amino-5-mercapto-1, 3, 4-thiadiazole according to claim 1, comprising the steps of:

s1, when preparation is needed, firstly, the connecting handle (16) is rotated, the connecting handle (16) drives the two first valves (15) to rotate, the left first valve (15) opens the left outlet of the conveying pipe (14), meanwhile, the right first valve (15) closes the right outlet of the conveying pipe (14), the rotating handle (25) is rotated, the rotating handle (25) drives the two second valves (26) to rotate, the left second valve (26) opens the left outlet of the connecting pipe (5), the right second valve (26) closes the right outlet of the connecting pipe (5), then the cover plate (23) is opened, required raw materials are poured into the feed hopper (21), then the cover plate (23) seals the feed hopper (21), the raw materials can fall to the guide plate (20), fluctuation flow is carried out through the convex shape on the surface of the guide plate (20), and meanwhile, the raw materials can flow to the bottom of the heat preservation box (1) along the inclined plane of the guide plate (20) in a staggered way, the raw materials can be premixed, the heating sheet (3) and the water pump (7) are controlled to work, the heating sheet (3) can heat the raw materials, the water pump (7) drives the connecting shaft (8) to rotate, the connecting shaft (8) drives the stirring blade (10) to rotate, the stirring blade (10) can mix the raw materials, meanwhile, the water pump (7) extracts the raw materials through the connecting pipe (5) and conveys the raw materials into the conveying pipe (14), and the raw materials are sprayed out of the heat preservation box (1) through the spraying head group (17), so that the raw materials can be mixed through the guide plate (20) again, and the raw materials can be uniformly heated in a circulating reciprocating mode;

s2, when the raw material is heated to a certain temperature, a steam problem is generated, steam can follow the raw material input conveying pipe (14), when the water pump (7) drives the connecting shaft (8) to rotate, the first gear (11) can be driven to rotate, the first gear (11) drives the second gear (914) to rotate, the second gear (914) drives the rotating shaft (99) to rotate, the rotating shaft (99) drives the half gear (910) to rotate, the half gear (910) drives the toothed rod (98) to move downwards, the toothed rod (98) drives the sliding rod (97) to move downwards, the sliding rod (97) drives the piston (92) to move downwards, the piston (92) compresses the spring (94), and because condensed water is arranged in the storage tank (915) and the condensation shell (912), the condensed water above the piston (92) can enter the bottom of the storage tank (915) through the one-way valve (93), the condensed water at the bottom is input into the pipeline (913) and the condensing shell (912) through pressure, the condensed water at the upper part of the condensing shell (912) can be input into the storage tank (915) through the pipeline (913), so that the condensed water can cool the surface of the conveying pipe (14), meanwhile, the steam can be condensed into water drops to be conveyed continuously, when the half gear (910) is separated from the rack bar (98), the spring (94) pushes the piston (92) to move upwards by utilizing the elasticity of the spring, when the half gear (910) is meshed with the rack bar (98) again, the work of exchanging the cooled water for condensation is carried out again, the work of condensation is carried out in a circulating and reciprocating way, meanwhile, the work of cooling the condensed water by the second semiconductor refrigerating sheet (95) can be controlled, whether the PH value of the raw material reaches the standard or not is detected by the PH value sensor (18), and when the temperature is detected by the temperature sensor (19) and heated, controlling the heating plate (3) and the second semiconductor refrigerating plate (95) to stop working;

s3, when cooling is needed, then the reverse rotation is changeed handle (25), make to change handle (25) and drive left side second valve (26) and close the left side export of connecting pipe (5), the right-hand member export of connecting pipe (5) is opened in right side d second valve (26) simultaneously, the work of first semiconductor refrigeration piece (4) of secondary control, make first semiconductor refrigeration piece (4) can carry out refrigerated work to the raw materials, make the raw materials flow back to connecting pipe (5) once more, and through connecting pipe (5) input conveyer pipe (14), spout through sprinkler head group (17) once more, and then can reciprocate the work of carrying out circulative cooling in proper order.
