To achieve the purpose, the utility model provides a quantitative supply device, which comprises a mixing box, wherein a feed inlet is arranged on the mixing box and used for adding water, a discharge outlet is arranged for discharging mixed water, a main stirrer is arranged, the output end of the main stirrer is connected with a main stirring rod and used for stirring the water in the mixing box, a charging barrel is also arranged for adding materials into the mixing box, a pre-stirring device is also arranged on the mixing box and comprises a pre-stirring barrel arranged in the mixing box, the pre-stirring barrel is arranged at the top of the inner side of the mixing box, the pre-stirring barrel is a vertical straight barrel, and the bottom of the pre-stirring barrel is open; be provided with the agitator in advance on the mixing box, the puddler in advance is connected to the agitator output, and is located the churn in advance with the puddler, the charging barrel export is located the churn in advance.

The utility model discloses a further improvement, the churn part is located below the mixing box internal liquid level in advance, stirring vane is located in the churn in advance and is located below the mixing box internal liquid level on the puddler in advance.

The utility model discloses a further improvement, churn lateral wall evenly distributed has the intercommunication bars in advance, the bar perforating hole that the intercommunication bars is vertical setting, and the intercommunication bars is located below the liquid level in the mixture at least part.

The utility model discloses a further improvement, the charging barrel export is located stirring vane top on the puddler in advance.

The utility model discloses a further improvement, agitator slew velocity is greater than main agitator in advance.

The application provides a quantitative supply device, the technological effect that its realization is as follows:

the material that the charging barrel added gets into in advance the churn earlier to carry out insufficient stirring through the agitator in advance in the churn, later the material with in advance the water in the churn through in advance churn lower part export and intercommunication bars scattered into the mixing box, accomplish whole stirring and mix. Because the volume is less in the churn in advance, the stirring vane diameter of agitator is also less in advance, can use less power can accomplish higher stirring work, and the material gets into in the churn in advance, through the quick stirring of agitator in advance, can accomplish with the preliminary mixing of part water, later mix with the water in the mixing box is whole again, has improved stirring efficiency.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

a quantitative supply device as shown in fig. 1-4, comprising a mixing tank 1, wherein the mixing tank 1 is provided with a feed inlet 3 for adding water, a discharge outlet 4 for discharging mixed water, a main stirrer 5, a main stirring rod 501 connected to the output end of the main stirrer 5 for stirring water in the mixing tank 1, a feed cylinder 2 for adding materials into the mixing tank 1, and a pre-stirring device on the mixing tank 1, wherein the pre-stirring device comprises a pre-stirring cylinder 9 arranged in the mixing tank 1, the pre-stirring cylinder 9 is arranged at the top of the inner side of the mixing tank 1, the pre-stirring cylinder 9 is a vertical straight cylinder, and the bottom of the pre-stirring cylinder is open; be provided with agitator 7 in advance on the mixing box 1, agitator 7 output connection in advance puddler 701 in advance is located churn 9 with the puddler in advance, 2 exports of charging barrel are located churn 9 in advance. The whole device is also provided with a control box 6, and all electrical components can be controlled through the control box 6.

The charging barrel 2 is connected into the mixing box 1 through a charging pipe 8, and an electronic flowmeter and an electromagnetic valve can be arranged on the charging pipe 8 to realize quantitative charging, which is a mature technology in the field and is not described in detail here.

As shown in fig. 4, the preliminary mixing drum 9 is located in the mixing tank 1, the preliminary mixing drum 9 is partially located below the liquid level in the mixing tank 1, and the mixing blade on the preliminary mixing rod 701 is located in the preliminary mixing drum 9 and below the liquid level in the mixing tank 1. The side wall of the pre-stirring cylinder 9 is uniformly distributed with communication grids 10, the communication grids 10 are vertically arranged strip-shaped through holes, and at least part of the communication grids 10 is positioned below the liquid level in the mixture. The outlet of the feeding pipe 8 is positioned above the stirring blades on the pre-stirring rod 701.

In the practical use process, because the inner diameter and the volume of the pre-stirring cylinder 9 are greatly smaller than those of the mixing box 1, the rotation speed of the pre-stirrer 7 can be far higher than that of the main stirrer 5 under the condition of using smaller power. The material that the charging barrel 2 added gets into in advance churn 9 earlier to carry out insufficient stirring through agitator 7 in advance in churn 9, later the material with in advance the water in churn 9 through the export of churn 9 lower part in advance and in the mixing box 1 is scattered to the intercommunication bars 10, accomplish whole stirring and mix. Because the volume is less in the churn 9 in advance, the stirring vane diameter of agitator 7 is also less in advance, can use less power can accomplish higher stirring work, and the material gets into in the churn 9 in advance, through the rapid mixing of agitator 7 in advance, can accomplish with the preliminary mixing of part water, later mix with the whole water that mixes in the mixing box 1 again, has improved stirring efficiency.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, but also to cover any modifications or equivalent changes made in the technical spirit of the present invention, which fall within the scope of the present invention.
