Detailed Description

The utility model is further illustrated below in conjunction with specific examples and experimental data. It should be understood that the embodiments of the present utility model are only for illustrating the present utility model and not for limiting the present utility model, and various substitutions and modifications made according to the general knowledge and conventional means of the person skilled in the art should be included in the scope of the present utility model without departing from the technical spirit of the present utility model.

Examples

As shown in fig. 1-2, a weighing hopper with flow control comprises a mounting frame 1 and a weighing charging barrel 2 arranged on the mounting frame 1, wherein the upper end of the weighing charging barrel 2 is connected with a feeding pipe 3, the lower end of the weighing charging barrel 2 is connected with a discharging pipe 4, a first flow regulating valve 5 is arranged between the weighing charging barrel 2 and the feeding pipe 3, the lower end of the discharging pipe 4 is connected with a second flow regulating valve 6, and a liquid level sensor 8 is arranged in an inner cavity of the weighing charging barrel 2.

During concrete production, raw materials are injected into the stirring hopper 2 from the feeding end 22 through the feeding pipe 3, enter the stirring part 9 through the feeding port 21 after passing through the feeding part 20, the stirring shaft 14 in the stirring part 9 is connected with the motor 24 to rotate in a following way, the stirring blade 16 arranged on the stirring shaft 14 stirs raw material mixed liquid, liquid and solid in the raw materials are mixed, the raw materials enter through the screening holes 21 on the screening plate 12, enter the discharging pipe 4 through the discharging port 19 after passing through the storage part 11, and finally the second flow regulating valve 6 is controlled to perform discharging according to actual production requirements.

The first flow regulating valve 5 and the second flow regulating valve 6 are pneumatic flow regulating valves with rubber sleeves arranged inside. The flow rate of the raw material liquid is controlled by controlling the amount of gas between the outer cover of the first flow rate adjusting valve 5 and the rubber tube sleeve, and the flow rate of the raw material liquid is controlled by controlling the amount of gas between the outer cover of the second flow rate adjusting valve 6 and the rubber tube sleeve. Pneumatic flow regulating valves are known in the art.

This application is specifically at last material end 22 and discharge gate 19 all are equipped with the flow control valve to cooperation level sensor 8, after level sensor 8 detects that the discharge end liquid level drops too soon, control first flow control valve 5 aerifys, and the cross-section that allows through diminishes in the control first flow control valve 5, slows down the pan feeding speed, and rethread stirring portion 9 fully stirs, promotes the product quality in later stage.
