Description

The constant pressure arrangement that rotary filling measurement is used

Technical field

The utility model belongs to package packing machine fields such as pharmacy, food, is specifically related to the constant pressure arrangement that rotary filling measurement is used in the liquid package container.

Background technology

At present at packaging fields such as pharmacy, food, beverages, generally one of canning means of Cai Yonging is isobaric constant current metering, its measuring principle is in unit time is passed through the certain cross-sectional area gained by the constant flow rate of constant pressure generation a flow, it is less to adopt the constant voltage jar to add the mode metering error of diaphragm valve metering filling in various can structures, can realize cleaning on the throne, sterilization on the throne, so tool has an enormous advantage.But this mode is imperfection also, there is the shortcoming that is difficult to constant pressure, the main mode of its constant voltage has: 1, directly carry liquid in fully enclosed constant voltage jar with liquid feeding pump, come control presssure by reflux line control quantity of reflux size, but because to be subjected to the quality problems of voltage disturbance and pump to cause pressure to be difficult to constant; 2, under the normal pressure situation, utilize liquidometer to control the constant of the interior water level of constant voltage jar, produce the water column high pressure of certain altitude, add that atmospheric pressure combined action forms the pressure of fluid constant voltage.But, be difficult to make water level constant because the frequent switch of pneumatic valve that liquidometer is controlled produces ripples and impacts; 3, under non-normal pressure situation, utilize constant air pressure to liquid effects, make it produce certain flow velocity, reach the purpose of isobaric constant current, but constant air pressure is difficult to control.

The utility model content

Technical problem to be solved in the utility model is the defective that overcomes above-mentioned prior art, and the constant pressure arrangement that provides a kind of later-model rotary filling measurement to use is to guarantee the accuracy of metering.

For achieving the above object, the technical solution adopted in the utility model is:

The constant pressure arrangement that a kind of rotary filling measurement is used, comprise the constant voltage jar of rotation and many connection pipes that constant voltage jar lower end is connected with, described connection pipe is connected with a filling valve, filling valve links to each other with filling tube, and constant voltage jar center is provided with stretches into actionless feed tube and counter flow pipe in the constant voltage jar, and feed tube links to each other with liquid feeding pump, the centre is provided with the pneumatic valve and the hand valve of dominant discharge, counter flow pipe links to each other with backwash pump, and feed tube has an adapter to link to each other with counter flow pipe, and hand valve is equipped with in the centre.

Described constant voltage jar is made up of upper tank body and lower tank, bucket and circular cone plate in being provided with in the lower tank.

Constant voltage jar of the present utility model divides inside and outside double-layer structure, when liquid feeding pump is input to the lower tank skin by feed tube with liquid, because the pneumatic diaphragm valve on the feed tube and the regulating action of manual diaphragm valve, guarantee the can amount of the flow of input greater than reality, excess liquid is just gone into interior bucket through interior jar upper surface overflow, by backwash pump liquid is extracted out and is gone.Liquid level is constant all the time in the time of so at any time can guaranteeing can, because gas communicates with barometric pressure in the constant voltage jar, like this, constant water column high pressure and constant atmospheric pressure have synthesized the constant power of liquid, constant flow velocity when keeping by filling valve, reach the purpose of constant flow rate in the unit time, simple in structure, practicability and effectiveness.

Description of drawings

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

Fig. 2 is the structural representation of constant voltage jar.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Description of reference numerals is as follows:

1---container 2---filling tube

3---filling valve 4---connection pipe

5---constant voltage jar 6---feed tube

7---counter flow pipes 8---are taken over

9---backflow hand valve 10---pneumatic valve

11---feed liquor hand valve 12---liquid feeding pump

13---backwash pump 14---lower tank

The interior bucket of 15---circular cone plates 16---

17---upper tank body

As Fig. 1, shown in Figure 2, the constant pressure arrangement that this rotary filling measurement is used is mainly by liquid feeding pump 12, backwash pump 13, constant voltage jar 5, filling valve 3, filling tube 2 is formed, wherein constant voltage jar 5 is positioned at filling valve 3 tops, join with it by connection pipe 4, constant voltage jar 5 is made up of upper tank body 17 and lower tank 14, bucket 16 and circular cone plate 15 in being provided with in the lower tank 14, filling valve connects filling tube 23 times, liquid feeding pump 12 is imported liquid in the constant voltage jar 5 by feed tube 6, the centre is provided with pneumatic valve 10 and feed liquor hand valve 11, backwash pump 13 links to each other with the interior bucket 16 of constant voltage jar 5 by counter flow pipe 7, and feed tube 6 has an adapter 8 to link to each other with counter flow pipe 7, and backflow hand valve 9 is equipped with in the centre.

Constant voltage principle of the present utility model is: when bottle placer moves, liquid feeding pump 12 startings, pneumatic valve 10 is opened, liquid is through feed liquor hand valve 11 and pneumatic valve 10, be input to by feed tube 6 in the skin of constant voltage jar lower tank 14, liquid flows into container 1 by connection pipe 4, filling valve 3 and filling tube 2, carry out can, bucket 16 in lower tank 14 excess liquid overflows are gone into, after pneumatic valve 10 is opened, have a spot of liquid to flow in the backwash pump 13 by taking over 8, auxiliary reflux pump 13 air-outs are extracted excess liquid out from interior bucket 16.So just, can under the can current intelligence, guarantee liquid level always, thereby reach the constant voltage effect.

The utility model is not limited to above-mentioned preferred forms, and anyone can draw other various forms of products under enlightenment of the present invention.Though but on its shape or structure, do any variation, every identical with the utility model or akin technical scheme is all within its protection domain.
