Problems solved by technology

[0007] In view of the problem that the existing filling device cannot efficiently and accurately control the liquid level, the present invention provides a non-contact liquid high-efficiency filling device. When filling liquid materials into the container, when the liquid level in the filled container rises When the measuring conduit is extended into the nozzle of the end, it will cause a rapid change in the internal pressure of the pipeline due to the action of the air source pressure in the pipeline, triggering the pressure detector, so as to control the filling action of the filling unit, so as to ensure that all The liquid level of the liquid material being filled in the container is consistent, achieving the effect of precise and efficient control of the filling liquid level

Embodiment 1

[0065] Such as figure 1 As shown, the non-contact liquid high-efficiency filling device of this embodiment includes,

[0066] Filling unit 1, which is used to fill liquid materials into containers;

[0067] The detection and control unit 2 is used to detect the height of the liquid material in the container to be filled, and to control the start and stop of the filling unit 1;

[0068] The detection and control unit 2 includes a measuring catheter 20 and a pressure sensor 21;

[0069] One end of the measuring conduit 20 extends into the container to be filled, and the other end is connected to the pressure sensor 21;

[0070] The pressure sensor 21 detects pressure changes in the measuring conduit 20 and is connected to the filling unit 1 for signal control to control the start and stop of the filling unit 1; it also includes

[0071] The air source 4 is connected with the measuring conduit 20 to provide constant air pressure in the measuring conduit 20 .

[0072] In the p...

Embodiment 2

[0078] Such as figure 2 , image 3 and Figure 4 As shown, the non-contact liquid high-efficiency filling device of this embodiment is further improved on the basis of Embodiment 1, and the gas source 4 provides a constant positive pressure for the measurement conduit 20 .

[0079] In this embodiment, the gas source 4 provides a constant positive pressure inside the tube by uniformly blowing air into the measuring tube 20 .

[0080] During filling, there is a positive pressure P in the measuring conduit 20 1, when the liquid level of the liquid material rises to the same height as the mouth of the measuring conduit 20, the pressure in the measuring conduit 20 suddenly increases, and the liquid level of the liquid material continues to rise, which is consistent with the liquid column formed in the measuring conduit 20. Height difference ΔH 1 , at this time there is still ΔP in the measuring catheter 20 1 = ρ 液态物料 ·g·ΔH 1 The pressure increases, where ρ 液态物料 The density...

Embodiment 3

[0082] Such as Figure 5 , Figure 6 and Figure 7 As shown, the non-contact liquid high-efficiency filling device of this embodiment is further improved on the basis of Embodiment 1, and the gas source 4 provides a constant negative pressure for the measurement conduit 20 .

[0083] In this embodiment, the gas source provides a constant negative pressure inside the tube by uniformly pumping air into the measuring tube 20 .

[0084] During filling, there is a negative pressure P in the measuring conduit 20 2 , when the liquid level of the liquid material rises to the same height as the mouth of the measuring conduit 20, because the density of the liquid material is much greater than the gas density, the negative pressure in the measuring conduit 20 suddenly increases, and the 20 pairs of liquid in the measuring tube The liquid level of the material forms a suction effect, and the liquid level of the liquid material in the measuring conduit 20 and the container quickly produ...

Abstract

The invention discloses a non-contact liquid high-efficiency filling device, which belongs to the technical field of filling. It includes a filling unit and a detection and control unit. The filling unit is used to fill liquid materials into the container; the detection and control unit includes a measuring conduit and a pressure sensor; one end of the measuring conduit extends into the container to be filled, and the other end is connected to the pressure sensor; The sensor detects the pressure change in the measuring conduit, and is connected with the filling unit signal to control the start and stop of the filling unit; it also includes an air source, which is connected with the measuring conduit to provide constant air pressure in the measuring conduit. When filling the liquid material in the present invention, when the liquid level in the container to be filled rises to the mouth of the measuring conduit extending into the nozzle, the pressure of the gas source in the pipeline will cause a rapid change in the pressure inside the measuring conduit, triggering the pressure detector, In this way, the filling action of the filling unit is controlled to ensure that the liquid levels of the filled liquid materials in all containers are consistent, and the effect of accurately and efficiently controlling the filling liquid level is achieved.

Description

technical field [0001] The invention belongs to the technical field of filling, and more specifically relates to a non-contact liquid high-efficiency filling device. Background technique [0002] In the hydration production line of the beverage industry, when it comes to the packaging of liquids, most of them use filling valves for filling. The accuracy requirements of the filled liquid level height are getting higher and higher, and many users have put forward requirements for the consistency of the liquid level height after liquid filling, which is a challenge for traditional filling valves. [0003] In the existing liquid filling procedures, most manufacturers use mechanical filling valves for liquid filling. This filling device is popular because of its low cost and convenient processing. However, the filling accuracy of mechanical filling valves Poor, the filling volume is difficult to control, and the valve closing time is long, which may easily cause large deviations...
