[0061] Term Explanation

[0062] Intermediate Bulk Container: The composite intermediate bulk container (hereinafter referred to as IBC container) is a type of packaging and turnover container widely used in the food, biochemical, pharmaceutical, chemical and other industries internationally. Since the IBC container can be reused multiple times, it has obvious advantages in filling, storage and transportation. Compared with round barrels, the IBC container can save 35% of storage space, its size conforms to the ISO standard, it is not only suitable for aseptic filling but also has a compact box body, which is convenient for large-scale safe and efficient storage. Therefore, it is widely used in the transportation, packaging and storage processes of materials in the form of liquids, granules and flakes. Currently, there are three existing specifications: 820L, 1000L, and 1250L. Generally, its composition structure includes a plastic inner liner (inner lining bag), a container, and a pusher. The top of the inner lining bag is provided with a filling port, the bottom of the inner lining bag is provided with a discharge port, and the discharge port is docked with the discharge channel on the container. The pusher squeezes the inner lining bag to discharge the liquid in the inner lining bag from the discharge port.

[0063] Embodiments of the present invention are described below with reference to the accompanying drawings. As Figure 1 and Figure 3 shown, an embodiment of the present invention relates to an auxiliary discharge device including: a base 1, a drive assembly 20, a connecting member 3, and a main control module. The main control module is electrically connected to the drive assembly 20, and the main control module controls the drive assembly 20 to retract and release the connecting member 3. The drive assembly 20 is disposed on the base 1, the connecting member 3 is connected to the drive assembly 20, and is pulled and lifted by the drive assembly 20. As Figure 5 shown, the base 1 can be placed on the top of the container 6 or on the ground, so that the drive assembly 20 and the connecting member 3 are located above the container 6, and the connecting member 3 is connected to the top of the inner lining bag 5. And the main control module can be a single-chip microcomputer or a controller such as a PLC, and is disposed in the electric cabinet 9. The electric cabinet 9 can be placed on the bottom surface, or can be welded or locked to the side wall of the container 6 by bolts.

[0064] As can be seen from the above, due to the provision of the base 1, the drive assembly, the connecting member 3 and the main control module, the drive assembly is arranged on the base 1, the connecting member 3 can be connected to the inner lining bag 5. After the liquid in the inner lining bag 5 is extruded, the drive assembly drives the connecting member 3 to lift the inner lining bag 5 away from the pusher 7, thus preventing the extruded part of the inner lining bag 5 from freely covering the surface of the pusher 7, resulting in the risk that the inner lining bag 5 is damaged by being rewound into the pusher 7 and affecting the discharge. Moreover, this structure is simple, has good manufacturing process, is easy to operate and saves costs.

[0065] Further, as Figure 1 and Figure 3 shown, the drive assembly includes: a power member 81 and a wire reel 82. The power member 81 is electrically connected to the main control module and is installed on the base. The wire reel 82 is connected to the power member 81 and is driven by the power member 81 to rotate for winding and unwinding the connecting member. The power member 81 includes: a mounting seat 812 fixed on the base 1 and a motor 811 installed on the mounting seat 812. The motor 811 is electrically connected to the main control module, and the main shaft of the motor 811 is connected to the wire reel 82. The main control module controls the rotation of the main shaft of the motor 811, and the wire reel 82 rotates following the main shaft of the motor 811 to wind up the connecting member, thereby straightening the inner lining bag.

[0066] Further, as Figure 1 and Figure 3 shown, as Figure 1 、 Figure 2 and Figure 5 shown, the base 1 includes: a connecting shaft 13, a first bracket 11 and a second bracket 12. Both the first bracket 11 and the second bracket 12 are mounted above the container 6. The connecting shaft 13 is connected to the mounting seat 812, the first bracket 11 is connected to the connecting shaft 13, and the second bracket 12 is connected to the connecting shaft 13. At least part of the second bracket 12 is separated from the first bracket 11 to form a placement space 10. The motor 811 and the connecting member 3 are located in the placement space 10. It can be understood that the first bracket 11 and the second bracket 12 can also be placed on the ground.

[0067] In addition, as Figure 1 and Figure 3 shown, the first bracket 11 is hinged to the connecting shaft 13, the second bracket 12 is hinged to the connecting shaft 13, and the first bracket 11 and the second bracket 12 rotate relative to each other. Thus, the included angle between the first bracket 11 and the second bracket 12 can be adjusted, enabling the base 1 to be applicable to different types of containers 6.

[0068] Further, as Figure 1 and Figure 3As shown in the figure, on the side of the first bracket 11 away from the connecting shaft 13, there is a first fixing member 110, and on the side of the second bracket 12 away from the connecting shaft 13, there is a second fixing member 120. The first fixing member 110 is connected to the first side of the container 6, and the second fixing member 120 is connected to the second side of the container 6, positioning the first bracket 11 and the second bracket 12.

[0069] Optionally, as Figure 1 and Figure 3 shown, the first fixing member 110 is a slot member, and the second fixing member 120 is a slot member. The first fixing member 110 clamps the first side, and the second fixing member 120 clamps the second side. It can be understood that the first fixing member 110 can be set as a locking member such as a clip or a screw, and the first fixing member 110 can also be set as a locking member such as a clip or a screw.

[0070] It can be understood that the base 1 can also be a rectangular column frame or a cylindrical frame, etc., which will not be elaborated here.

[0071] In addition, as Figure 1 、 Figure 2 、 Figure 3 and Figure 6 shown, the connecting member 3 includes a hanging plate and a flexible member 33 connected to the hanging plate. There is a buckle position on the hanging plate, and the top end of the inner lining bag 5 is installed at the buckle position. The two ends of the flexible member 33 are respectively connected to the wire reel 82 of the driving assembly and the hanging plate. When the liquid in the inner lining bag 5 is gradually squeezed out, the motor 811 rotates to drive the wire reel 82 to rotate, the flexible member 33 is wound onto the wire reel 82, and the hanging plate drives the part of the inner lining bag 5 from which the liquid is squeezed out to be pulled up. The flexible member 33 can be a pull rope or a chain.

[0072] Optionally, as Figure 2 and Figure 5 shown, the buckle position is an open slot 320. Specifically, the hanging plate includes: a plate body 31 connected to the flexible member 33, and a buckle member 32 connected to the plate body 31. The plate body 31 and the buckle member 32 can be integrally formed, or connected by bolts, or welded. The buckle member 32 includes a first side plate 321, a second side plate 322 opposite to the first side plate 321, and a main plate 323 connecting the first side plate 321 and the second side plate 322. Both the first side plate 321 and the second side plate 322 are connected to the plate body 31, the main plate 323 is spaced apart from the plate body 31, and the buckle member 32 and the plate body 31 surround to form an accommodating area 30. There is an open slot 320 on the buckle member 32 communicating with the accommodating area 30, and the side of the open slot 320 facing the driving assembly is the open area. In one embodiment, as Figure 1 shown, at the discharge port at the bottom end of the inner lining bag 5, there is a filling port 51 at the top end of the inner lining bag 5. Liquid can be poured into the inner lining bag 5 from the filling port, and the liquid is discharged from the discharge port during use. As Figure 1 、 Figure 2 、Figure 5 and Figure 6 As shown in Figure 6 , the filling port 51 includes a flange 511 and a mating port 512 connected to the flange 511. The diameter of the mating port 512 is smaller than the diameter of the flange 511, and a clamping step surface 5120 is provided around the mating port 512. During installation, the mating port 512 slides down along the opening area of the opening groove 320 and enters the opening groove 320. The mating port 512 is located within the accommodation area 30. One side of the flange 511 facing the mating port 512 abuts against the main board 323, and the side wall of the opening groove 320 clamps the clamping step surface 5120, thereby connecting the inner lining bag 5 to the hanging board. When the hanging board is driven by the driving component to rise, the liquid-extruded part of the inner lining bag 5 can be driven by the hanging board to rise together. This structure is simple, easy to install, and has a low cost.

[0073] It can be understood that the snap position can also be a protruding part, such as a hook or a tightening clamp ring provided on the hanging board. The hook hooks the top end of the inner lining bag 5, and the tightening clamp ring sleeves the mating port 512. The hanging board can also be a flat panel or other structures.

[0074] In addition, as Figure 1 、 Figure 2 and Figure 4 shown, a suspension hole 310 is provided on the board body 31, and a hook is connected to the flexible member 33. The hook can directly hook the suspension hole 310, or the suspension hole 310 can be connected by a rope, so that the hanging board can rise in balance when it rises.

[0075] In addition, the connecting member 3 may not be a hanging board, but components such as a clip, a rope, a hook, etc., to fix the top end of the inner lining bag 5.

[0076] In another embodiment, the auxiliary discharge device further includes an induction module electrically connected to the main control module; wherein, the induction module is used to trigger the main control module to control the driving component to start when the tension on the connecting member is less than a preset tension; and is also used to trigger the main control module to control the driving component to stop when the tension on the connecting member is greater than or equal to the preset tension.

[0077] Specifically, as Figure 7As shown, the induction module is disposed between the flexible member 33 and the hanging plate, and two ends of the induction module are respectively connected to the flexible member 33 and the hanging plate. The induction module is a tension sensor 21. When the tension sensed by the tension sensor 21 is greater than or equal to a preset tension, that is, when the inner lining bag is tightened, the tension sensor 21 sends a signal to the main control module, and the main control module controls the motor 811 to stop working, and the wire winder 82 no longer winds up the flexible member 33. When the tension sensed by the tension sensor 21 is less than the preset tension, that is, when the inner lining bag 5 is in a loose state, the tension sensor 21 sends a signal to the main control module, and the main control module controls the motor 811 to start, and the wire winder 82 winds up the flexible member 33 to straighten the liquid-extruded part of the inner lining bag 5. And the flexible member 33 can hook the tension sensor 21 through a hook or can be directly tied to the tension sensor 21.

[0078] In addition, the induction module is a voltage sensor. The voltage sensor can be directly installed in the electrical cabinet 9 and is electrically connected to the main control module. When the pressure value received by the voltage sensor is greater than or equal to a preset value, that is, when the tension on the connecting member is greater than or equal to the preset tension, the main control module is triggered to control the driving assembly to start.

[0079] Further, as Figure 8 、 Figure 9 、 Figure 10 and Figure 11 shown, the induction module includes: an elastic member 22 connecting the flexible member 33 and the hanging plate, a proximity switch 23 electrically connected to the main control module, and an induction member 24. The induction member 24 can be a metal protrusion. The proximity switch 23 and the induction member 24 are respectively disposed at two ends of the elastic member 22. The proximity switch 23 is disposed at one end of the elastic member 22 facing the flexible member 33, and the induction member 24 is disposed at one end of the elastic member 22 facing the hanging plate. The elastic member 22 is a tension spring. Specifically, when the inner lining bag 5 is tightened, the elastic member 22 is stretched, the proximity switch 23 and the induction member 24 are separated, and the proximity switch 23 cannot sense the induction member 24, and the main control module does not turn on the motor 811. When the inner lining bag 5 is in a loose state, two ends of the elastic member 22 approach, the proximity switch 23 and the induction member 24 approach, and the proximity switch 23 senses the induction member 24, and the main control module does not turn on the motor 811. And the positions where the proximity switch 23 and the induction member 24 are placed can be swapped. The elastic member 22 can also be an elastic pad in addition to being a spring.

[0080] An embodiment of the present invention further provides a fluid discharge system, as Figure 3As shown in the figure, it includes: an inner lining bag 5, a container 6, a pusher 7 and an auxiliary discharge device. The inner lining bag 5 is placed inside the container 6. The container 6 is provided with a discharge channel for installing the discharge port of the inner lining bag 5. The pusher 7 clamps the inner lining bag 5 and squeezes the liquid inside the inner lining bag 5. The base of the auxiliary discharge device is arranged on the container 6. The base 1 supports the drive assembly and the connecting piece 3 above the container, and the connecting piece 3 of the auxiliary discharge device is connected to the top end of the inner lining bag 5. When the pusher 7 squeezes the liquid inside the inner lining bag 5, the liquid inside the inner lining bag 5 is discharged from the discharge port through the discharge channel, and the auxiliary discharge device lifts the part of the inner lining bag 5 from which the liquid is squeezed out, so that the part of the inner lining bag 5 from which the liquid is squeezed out is away from the pusher 7. The pusher 7 includes: a roller 71 and a roller 72. When it is necessary to discharge the liquid inside the inner lining bag 5, the roller 71 and the roller 72 clamp the inner lining bag 5. Under the drive of the drive device, the pair of pusher parts move relatively. For example, the roller 71 and the roller 72 rotate in opposite directions relatively, applying a squeezing force to the inner lining bag 5, so as to squeeze and discharge the liquid inside the inner lining bag 5. During the liquid discharge process, as the liquid inside the inner lining bag 5 decreases, the two rollers automatically descend with the liquid level under the drive of the drive device and squeeze the liquid. The specific structure of the pusher 7 can refer to the pusher 7 in the patent application document with the application number 2019102132760, which will not be elaborated here.
