This patent application claims priority to a Chinese patent application filed on September 17, 2020, bearing application number 202010980159X, and entitled "Fluid Discharge System and Its Discharge Assistance Device," the entire text of which is incorporated herein by reference.

Embodiments of the present invention relate to containers, and in particular to fluid discharge systems and associated discharge assistance devices.

There are many liquid storage and transport devices currently on the market for storing, transporting, filling and discharging viscous liquids.

Patent document 1 (US5765723A) discloses a sealed liquid bag in which the main body is a sealed soft container made of PVC coated fabric and produced by hot melt welding or high frequency welding, and a liquid inlet valve and a liquid outlet valve are provided at both ends of the sealed soft container. This liquid liner bag is generally relatively effective when used with high flow rate, fluid liquids, but when discharging viscous liquids, the discharge of liquid is slow and inefficient.

Patent document 2 (IL156984A) discloses a sealed soft container whose main body is made of PVC coated fabric or PE film and is manufactured by hot melt welding or high frequency welding, and both ends of the sealed soft container are provided with a liquid inlet valve and a liquid outlet valve, the main body further includes an air bag to assist in discharge, and a sealed liquid bag is provided with an air intake port for filling the air bag with air. In the process of discharging the liquid, it is necessary to fill an auxiliary gas bag with air and discharge the viscous liquid by pushing it out with the gas. This is inefficient and increases costs.

Patent document 3 (US2015284181A1) discloses a sealed liquid bag in which the main body is a sealed soft container made of PVC coated cloth or PE film and produced by thermal welding or high frequency welding, and when discharging a viscous liquid, a medium-sized bulk container transporting the liquid uses a mechanical mechanism to tilt the bottom of the medium-sized bulk container so that the discharge outlet is at the lowest point. This operation is time-consuming, inefficient, and difficult to operate.

Both ends of the flexible member 33 connect the winder 82 of the drive assembly to the hanging plate, respectively. As the liquid in the liner bag 5 is gradually pushed out, the electric motor 811 rotates to drive and rotate the winder 82, and the flexible member 33 is wound around the winder 82, and the hanging plate pulls and lifts the portion of the liner bag 5 from which the liquid has been pushed out. The flexible member 33 may be a pulling rope or a chain.

2 and 5, the snap location is an open groove 320. Specifically, the hanging plate includes a plate body 31 connected to a flexible member 33 and a snap member 32 connected to the plate body 31, and the plate body 31 and the snap member 32 may be integrally molded, connected by a bolt, or welded. The snap member 32 has a first side plate 321, a second side plate 322 installed opposite the first side plate 321, and a main plate 323 connecting the first side plate 321 and the second side plate 322, and the first side plate 321 and the second side plate 322 are both connected to the plate body 31, the main plate 323 is spaced apart from the plate body 31, and the snap member 32 surrounds the plate body 31 to form the storage area 30. The snap member 32 is provided with an opening groove 320 communicating with the storage area 30, and the opening groove 320 has an opening area on the side facing the drive assembly. In one embodiment, as shown in Fig. 1, a discharge port is provided at the bottom end of the liner bag 5, and a filling port 51 is provided at the top end of the liner bag 5, and liquid can be injected into the liner bag 5 through the filling port 51, and the liquid is discharged from the discharge port during use. As shown in Figs. 1, 2, 5 and 6, the filling port 51 has a flange 511 and a joint port 512 connected to the flange 511, the diameter of the joint port 512 is smaller than the diameter of the flange 511, and a positioning step surface 5120 is provided around the joint port 512. During installation, the joint port 512 slides down into the opening groove 320 along the opening area of the opening groove 320, the joint port 512 is located in the receiving area 30, the side of the flange 511 facing the joint port 512 abuts the main plate 323, and the side wall of the opening groove 320 engages the positioning step surface 5120, so that the liner bag 5 is connected to the hanging plate, and when the hanging plate is pulled up by the drive assembly, the part of the liner bag 5 from which the liquid has been pushed out can be pulled up by the hanging plate and rise together. This configuration is simple, convenient to install, and low cost.

It is understood that the snap point may be a protruding member such as a hook or a tight snap ring provided on the hanging plate, and the hook can hook onto the top end of the liner bag 5, and the tight snap ring can engage with the joint opening 512. The hanging plate may also be a flat plate or other configuration.

As shown in Figures 1, 2, and 4, a hanging hole 310 is provided in the plate body 31, and a hook is connected to the flexible member 33.

In another embodiment, the discharge assistance device further includes a sensing module electrically connected to the main control module, the sensing module being used to trigger the main control module to control the drive assembly to start when the tensile force in the connection member 3 is less than a preset tensile force, and also being used to trigger the main control module to control the drive assembly to stop when the tensile force in the connection member 3 is greater than or equal to the preset tensile force.

Specifically, as shown in FIG. 7, a sensing module is installed between the flexible member 33 and the hanging plate, and both ends of the sensing module are connected to the flexible member 33 and the hanging plate, respectively. The sensing module is a tensile force sensor 21. When the tensile force sensed by the tensile force sensor 21 is equal to or greater than the preset tensile force, that is, when the liner bag 5 is pulled, the tensile force sensor 21 sends a signal to the main control module, which controls the electric motor 811 to stop operation and prevents the winder 82 from winding the flexible member 33. When the tensile force sensed by the tensile force sensor 21 is smaller than the preset tensile force, that is, when the liner bag 5 is in a loose state, the tensile force sensor 21 sends a signal to the main control module, which controls the electric motor 811 to start, and the winder 82 winds the flexible member 33, pulling the part of the liner bag 5 from which the liquid has been extruded taut. Furthermore, the flexible member 33 may be hooked onto the tensile force sensor 21 by a hook, or may be directly fastened to the tensile force sensor 21.

The sensing module is also a voltage sensor that can be directly mounted in the electrical cabinet 9 and is electrically connected to the main control module, and triggers the main control module to control the drive assembly to start when the pressure value received by the voltage sensor is equal to or greater than a preset value, i.e., when the tensile force in the connection member 3 is equal to or greater than a preset tensile force.

The proximity switch 23 is provided at one end of the elastic member 22 facing the flexible member 33, and the sensing member 24 is provided at one end of the elastic member 22 facing the hanging plate, and the elastic member 22 is a tension spring. Specifically, when the liner bag 5 is pulled, the elastic member 22 is pulled away, the proximity switch 23 and the sensing member 24 are separated, the proximity switch 23 does not sense the sensing member 24, and the main control module does not start the electric motor 811. When the liner bag 5 is loosened, both ends of the elastic member 22 approach each other, the proximity switch 23 and the sensing member 24 approach each other, the proximity switch 23 senses the sensing member 24, and the main control module does not activate the electric motor 811. In addition, the positions of the proximity switch 23 and the sensing member 24 may be interchanged. The elastic member 22 may be an elastic pad other than a spring.

The present invention also provides a fluid discharge system including a liner bag 5, a container 6, an extruder 7, and a discharge auxiliary device, as shown in FIG. 3. The liner bag 5 is disposed in the container 6, the container 6 has a discharge passage to which the discharge port of the liner bag 5 is attached, and the extruder 7 clamps the liner bag 5 to extrude the liquid in the liner bag 5. The base 1 of the discharge auxiliary device is installed in the container 6, and the base 1 supports a drive assembly and a connection member 3 above the container 6, and the connection member 3 of the discharge auxiliary device is connected to the top end of the liner bag 5. When the extruder 7 extrudes the liquid in the liner bag 5, the liquid in the liner bag 5 is discharged from the discharge passage through the discharge port, and the discharge auxiliary device pulls up the portion of the liner bag 5 from which the liquid is extruded, moving the portion of the liner bag 5 from which the liquid is extruded away from the extruder 7. The extruder 7 includes a roll shaft 71 and a roll shaft 72. When it is necessary to discharge the liquid in the liner bag 5, the roll shaft 71 and the roll shaft 72 sandwich the liner bag 5. When the driving device is driven, the pair of extruders perform relative motion, such as rotating the roll shaft 71 and the roll shaft 72 in the opposite direction relative to each other, to apply a pushing force to the liner bag 5, thereby pushing out and discharging the liquid in the liner bag 5. As the liquid in the liner bag 5 decreases during liquid discharge, the two roll shafts are automatically lowered together with the liquid level by the driving device, pushing out the liquid. The specific configuration of the extruder 7 can be referred to in the patent application documents of application number 2019102132760, and will not be described in detail here.

Although preferred embodiments of the present invention have been described in detail above, it should be understood that aspects of the embodiments can be modified, if necessary, to provide additional embodiments using aspects, features, and concepts of various patents, applications, and publications.
