Description

A kind of additive essence metering device

Technical field

This utility model is related to a kind of additive essence metering device, belongs to technical field of concrete construction.

Background technology

With the fast development of high-speed railway, highway and high-rise building in recent years, will to the quality of concrete Ask increasingly stricter, it is common one kind side in concrete construction to add liquid additive for change concrete performance Method, the requirement to the species and measuring accuracy of additive in concrete are also more and more stricter.

At present, the additive feeding tube of most of concrete mixing plants mostly selects 1 cun of steel pipe, its problem for existing now It is, the additive less for consumption, although requirement of the country to additive measuring accuracy ± 1% can be met, but to static essence Degree ± 0.5% requirement but it is difficult to ensure that, thus affect engineering entity in concrete performance.

Utility model content

In order to solve technical problem present in background technology, this utility model provides a kind of additive essence metering dress Put, the additive essence metering device is mainly made up of additive main line, temporary bucket and additional jizi for making dumplings pipeline, its simple structure, It is easy to operate；Building site additive metering precision after using this set additive essence metering system increases, and is entirely capable of reaching Requirement of the country to additive measuring accuracy.

What technical solution of the present utility model was realized in：

A kind of additive essence metering device, which includes that additive is responsible for, and one end of the additive supervisor is vertically connected with Upper additive pipe, the upper additive pipe are connected with additive pump, are vertically connected with additional jizi for making dumplings on the additive supervisor Pipe, the other end of the additive supervisor are vertically connected with temporary bucket, and the bottom of the temporary bucket is communicated with additive adding tube, Controllable valve is provided between the additive adding tube and temporary bucket.

Wherein, the upper additive pipe and additional jizi for making dumplings pipe are 1 writing brush, and the additive adding tube is two/one-inch Pipe.

1 described writing brush refers to a diameter of 25mm of pipe, and 1/2nd described writing brushes refer to a diameter of 12.5mm of pipe.

Preferably, the controllable valve is butterfly valve.

Preferably, the pipeline inside diameter of the butterfly valve is 50mm.

The butterfly valve is called flap valve, is a kind of regulating valve of simple structure, it is general mainly include valve body, valve rod, valve shaft, The critical piece such as driving means and butterfly plate, can be used for the on-off control of low pressure pipeline medium, by butterfly plate around valve shaft rotate come Reach open and close, valve can be used to controlling empty gas and water, steam, various Korrosionsmediums, mud, oil product, liquid metal and The flowing of all kinds fluid such as radiating medium.Cut-out and throttling action are acted primarily as on pipeline.Butterfly valve opening and closing element is one Discoidal butterfly plate, rotates around the axis of its own in valve body, so as to reach the purpose for opening and closing or adjusting.

The beneficial effects of the utility model are：

1st, this utility model is provided with temporary bucket, when the conveying capacity of the main transfer pipeline of additive reaches value set in advance When, supply additive can be continued by temporary bucket, as the adding speed and addition of keeping in the additive in bucket are easily controls System, it is possible to effectively improve the precision of additive metering；

2nd, this utility model simple structure, it is easy to operate.

Description of the drawings

Fig. 1 is structural representation of the present utility model；

Fig. 2 is butterfly valve mplifying structure schematic diagram in this utility model；

In figure, 1- additives supervisor, the additional jizi for making dumplings pipes of 2-, the upper additive pipes of 3-, the temporary buckets of 4-, 6 additive of 5- butterfly valves add Plus pipe.

Specific embodiment

This utility model is further described with specific embodiment below with reference to accompanying drawings.

As shown in Figure 1 and Figure 2, a kind of additive essence metering device, which includes additive supervisor 1, and additive is responsible for the one of 1 The upper additive pipe 3 of end vertical connection one, upper additive pipe 3 connect upper additive pump, vertical connection one on additive supervisor 1 Additional jizi for making dumplings pipe 2, vertically bucket 4 is kept in connection one to the other end of additive supervisor 1, keeps in 4 bottoms of bucket and connects an additive Adding tube 6, arranges butterfly valve 5 between additive adding tube 6 and temporary bucket 4.

The pipeline inside diameter of butterfly valve 5 is 50mm.

Upper additive pipe 3 and additional jizi for making dumplings pipe 2 are 1 writing brush.

Additive adding tube 6 is 1/2nd writing brushes.

This utility model starts upper additive pump when in use, first, and additive enters additive along upper additive pipe 3 Supervisor 1, by additional 2 normal feed of jizi for making dumplings pipe, when amount to be conveyed reaches 95% (adjustable) of setting value, upper additive pump stops Work, opens butterfly valve 5, the feed by temporary bucket 4, stops supplying to be delivered to temporary bucket butterfly valve 5 is closed during weighing hopper setting value Material.

Additive metering precision can be effectively improved using the additive essence metering device, be entirely capable of reaching country to additional The requirement of agent measuring accuracy.

The additive essence metering device simple structure, it is easy to operate.

Finally it should be noted that：Embodiment described above is merely to illustrate the technical solution of the utility model, rather than right Its restriction；Although being described in detail to this utility model with reference to the foregoing embodiments, one of ordinary skill in the art should Work as understanding：Which still can be modified to the technical scheme described in previous embodiment, or to which part or whole skills Art feature carries out equivalent；And these modifications or replacement, do not make the essence of appropriate technical solution depart from this utility model each The scope of embodiment technical scheme.
