[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0018] Example: See Figure 1-3 The utility model provides a technical solution: a precipitation reactor, comprising a reactor 1, a top cover box 3 with a cavity is provided on the top of the reactor 1, a stirring motor 6 is installed on the top of the top cover box 3, a reaction liquid inlet pipe 4 is connected to one side of the reactor 1, a flushing water inlet pipe 5 is connected to the other side of the reactor 1, a filter plate 2 is installed at the bottom end of the reactor 1, and a discharge pipe 11 is connected to the bottom of the reactor 1.

[0019] A precipitant inlet 8 is connected to one side of the top of the top cover box 3 , and a plurality of precipitant discharge ports 302 are evenly arranged at the bottom of the top cover box 3 .

[0020] The bottom of the stirring motor 6 is connected to a stirring rod 7 , and the top of the top cover box 3 is installed with a thermometer 10 and a safety valve 9 .

[0021] The filter plate 2 is provided with a plurality of filter holes.

[0022] The reaction liquid inlet pipe 4 and the flushing water inlet pipe 5 are both welded to the reactor 1 .

[0023] The top cover box 3 is connected to the reaction kettle 1 in a sealed manner.

[0024] Working principle: A precipitation reactor, a flushing water inlet pipe 5 is added to the side of the reactor 1, and the precipitant is added from the precipitant inlet 8 above the top cover box 3. The top cover box 3 is hollow. In addition to the necessary equipment ports such as stirring paddles, safety valves, thermometers, etc., the bottom of the hollow top cover box 3 is provided with a number of precipitant discharge ports 302 with a diameter of about 1 mm. The diameter size is specifically designed according to the experimental requirements. When no pressure is applied, the precipitate will not be injected due to the surface tension. When a certain pressure is applied, the precipitant will form liquid lines like rain and be evenly added to the reaction liquid. In addition, the stirring motor 6 drives the stirring rod 7 to rotate, thereby achieving stirring and improving the reaction efficiency.

[0025] A flushing water inlet pipe 5 is added on the side of the reactor 1. The flushing water inlet pipe 5 is tangent to the inner wall of the reactor. The water outlet direction of the flushing water inlet pipe 5 is in line with the inner wall of the reactor, so that the water discharged through the flushing water inlet pipe 5 can flow in line with the inner wall of the reactor. When a cleaning liquid with a certain pressure is added, the cleaning liquid will spirally flush along the inner wall of the reactor to flush the sediment to the bottom.

[0026] The above embodiments only express the implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
