task of the present invention is accomplished like this, and a kind of device of chemical products moment reaction usefulness comprises a charge groove; One drops down hopper; This drops down hopper and is hinged on the described charge groove, and is equipped with a carriage, and the top of this carriage is hinged with the back of dropping down hopper; And the bottom of carriage is expanded and to be provided with a fixed head, and fixed head is fixed on the terrace of field of employment or is fixed on the frame that is placed in the field of employment; One is used for first raw material is caused the first raw material inlet tube that drops down hopper, and an end of this first raw material inlet tube offers the material shooting hole that is used for first raw material is fed and dropped down hopper corresponding to the top of dropping down hopper and with the interval state, and the other end is equipped with a valve; One is used for second raw material is caused the second raw material inlet tube that drops down hopper; This second raw material inlet tube is equipped with a feed nozzle towards a said end that drops down hopper; This feed nozzle is corresponding with the described top of dropping down hopper; And the length of this feed nozzle adapts with the width that drops down hopper, and wherein: the described top of dropping down hopper constitutes a material overflow cavity, and the length of a said end of the said first raw material inlet tube and the length of said feed nozzle are consistent.
respectively have a hinged seat in the upper edge of the corresponding both sides of described charge groove in a concrete embodiment of the present invention, the corresponding both sides of the described bottom of dropping down hopper are respectively hinged through jointed shaft and hinged seat.
in another concrete embodiment of the present invention, the shape of cross section of described feed nozzle is the triangle with opening.
Hopper is describedly dropped down and described charge groove is perpendicular in
in another concrete embodiment of the present invention.
Hopper is describedly dropped down and described charge groove tilts in
in another concrete embodiment of the present invention.
also have among the concrete embodiment of the present invention, and the angle of said inclination is 10-85 °.
technical scheme provided by the invention has been owing to abandoned reaction vessel such as the agitated reactor in the prior art, thereby can satisfy first, second raw material and dropping down the requirement of accomplishing the moment reaction on the hopper each other; Owing to can avoid successive reaction, thereby can economize in raw materials and ensure the quality of product; Overall structure is simple.
