AI Technical Summary
During the liquid filling process, the cuffs of the inner liner bag are unstable and tend to shrink into the ton container, causing liquid material to enter between the ton container and the inner liner bag, thus failing to achieve the ton container's no-cleaning effect.
By setting external threads on the inlet pipe of the ton container, the cuff of the inner liner bag is turned outward to fit the inlet pipe and tightened with a rubber ring. Combined with the design of the inner plug and pressure ring, the cuff is kept in close contact with the inner wall of the inlet pipe. The lid is threaded to the inlet pipe, and the pressure ring is fixed by the downward pressure of the lid. The sealing ring and flexible flat opening are used to prevent splashing liquid. The upper flange and positioning ring are designed to prevent loosening. The threaded hole and plug design are used to prevent air from entering when pumping liquid.
This design achieves stable fixation of the inner lining bag cuffs, preventing collapse, ensuring sealing performance, preventing liquid splashing and air ingress, and improving the sealing and operational stability of the ton container.

TECHNICAL FIELD
[0001] The utility model relates to ton barrel technical field, specifically is a kind of inner lining bag ton barrel entrance installation structure. BACKGROUND
[0002] The ton barrel with inner lining bag, liquid material is filled in inner lining bag, to achieve the purpose of ton barrel cleaning-free.
[0003] To avoid filling, liquid material enters the area between ton barrel and inner lining bag, generally, the cuff of inner lining bag is stretched upwards from the entrance of ton barrel, then is turned outwards.
[0004] Due to the unstable structure of inner lining bag cuff, the impact force generated by liquid during liquid filling can drive inner lining bag to descend, so that cuff is retracted into ton barrel, thereby causing liquid to be filled between inner lining bag and inner wall of ton barrel, and the purpose of ton barrel cleaning-free cannot be achieved. UTILITY MODEL CONTENTS
[0005] To solve the technical problems in the background art, the utility model discloses a kind of inner lining bag ton barrel entrance installation structure.

[0007] Ton barrel, its upper side is provided with the entrance pipe extending upwards, and the entrance pipe is provided with external thread;
[0008] Inner lining bag, the cuff of which is sleeved on the pipe wall of entrance pipe by turning outwards;
[0009] Rubber ring, the outer side of cuff is sleeved, and cuff is clamped on entrance pipe;
[0010] Inner plug, inserted into entrance pipe, so that the part of cuff located in entrance pipe is clamped between inner plug and inner wall of entrance pipe;The upper end of inner plug is provided with outwardly protruding pressing ring, and pressing ring abuts against the upper end of entrance pipe;
[0011] Sealing ring, sleeved on inner plug, and clamped between pressing ring and entrance pipe;
[0012] Bucket cover, threadedly connected with entrance pipe;When bucket cover is locked, downward pressure is generated on pressing ring.
[0013] The beneficial effects of the above arrangement are: 1. The part of the sleeve located in the inlet pipe is limited by the inner plug, so that it keeps in close contact with the inner wall of the inlet pipe, and the structure is more stable; 2. The setting of the compression ring fixes the part of the sleeve located at the upper end of the inlet pipe; 3. The barrel cover is threadedly connected with the inlet pipe, so that the part of the sleeve in contact with the outer wall of the inlet pipe is locked between the inner thread of the barrel cover and the outer thread of the inlet pipe, so that the position of the sleeve is more stable; therefore, when the inner liner bag is subjected to the impact force of the filled liquid, the sleeve can still keep the position stable, so that the inner liner bag will not collapse.
[0014] The position stability of the sealing ring directly affects its sealing performance, and based on this, the further improvement is that the inner plug is composed of a plug body and a compression ring in a T shape; a recessed limiting groove is arranged at the connection between the plug body and the outer wall of the compression ring, and is used for clamping the sealing ring.
[0015] Since the impact during liquid material filling can cause splashing, the splashed liquid is easy to fly out from the inlet pipe, and based on this, the further improvement is that the utility model also includes a flexible flat mouth; the flat mouth is composed of a sleeve and a conical pipe; the conical pipe is connected with the sleeve at the necked end; the sleeve is located at the upper side, is sleeved with the inlet pipe in an outward turning manner, and covers the sleeve; the inner plug is inserted into the sleeve. When filling the liquid, the conical pipe is pulled out upward and unfolded, so as to block the splashed liquid.
[0016] When filling the liquid, the barrel cover needs to be removed, so that the sleeve is only fixed by the rubber ring, the connection strength is low, and the sleeve is easy to be separated from the inlet pipe, and based on this, the further improvement is that the utility model also includes an upper flange which is threadedly connected with the inlet pipe; the upper end of the upper flange is provided with an annular pressing plate which protrudes inward; the lower end surface of the pressing plate abuts against the upper end surface of the compression ring; the upper flange is provided with an external thread; and the barrel cover is threadedly connected with the upper flange.
[0017] Further, a sealing gasket is arranged between the barrel cover and the upper flange, which is used for sealing and avoiding air entering the ton barrel and contacting the liquid material.
[0018] Since the upper flange can self-rotate under the condition of wrong external force or vibration, causing loosening, and based on this, the further improvement is that the side wall of the upper flange is connected with a positioning ring, a plurality of rotationally symmetrical positioning holes are arranged on the positioning ring; and a positioning block for clamping the positioning hole is arranged on the upper side surface of the ton barrel.
[0019] Further, the positioning ring is made of flexible material. In this way, when the upper flange needs to be disassembled, the positioning ring is first lifted upward and away from the positioning block, so that the positioning ring can be prevented from being blocked by the positioning block.
[0020] When draining, if the space for draining is not available on site, the liquid in the inner liner bag needs to be extracted from the inlet, and the barrel cover is removed, the space between the extraction pipe and the inner wall of the upper flange is large, and a large amount of air is easy to enter the ton barrel to cause the liquid material to deteriorate, based on this, the further design is that the barrel cover is provided with an axially arranged threaded hole for inserting the extraction pipe to extract the liquid in the inner liner bag; the threaded hole is gap fitted with the extraction pipe; the threaded hole is threadedly connected with a plug.
[0021] The utility model discloses the beneficial effects are: 1, the part of the sleeve is limited by the inner plug and makes it keep the state of being attached to the inner wall of the inlet pipe, and the structure is more stable;2, the setting of the compression ring makes the part of the sleeve fixed on the upper end of the inlet pipe;3, the barrel cover is threadedly connected with the inlet pipe, makes the part of the sleeve contact with the outer wall of the inlet pipe lock in between the inner thread of the barrel cover and the outer thread of the inlet pipe, makes the position of the sleeve more stable;Therefore, when the inner liner bag is impacted by the liquid, the sleeve can still keep the position stable, so that the inner liner bag does not collapse.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0033] like Figures 1-5 As shown, this utility model discloses an inlet installation structure for a ton container 1 with an inner liner bag, including a ton container 1, an inner liner bag 3, and a flat opening 12. An upwardly extending inlet pipe 2 is provided on the upper side of the ton container 1, and the inlet pipe 2 has external threads. The inner liner bag 3 has an upward-facing cuff 4, through which liquid materials are filled into the inner liner bag 3.
[0034] The specific installation structure of the cuff 4 and the inlet pipe 2 is as follows: the cuff 4 forms a U-shape with the opening facing downwards by turning outwards, and fits over the inner and outer walls of the inlet pipe 2, such as... Figure 6 As shown, the end of the cuff 4 extends vertically outward, and its extension fits against the upper side of the ton 1. An elastic rubber ring 5 is fitted at the base of the extension to tighten the cuff 4 at the base of the inlet pipe 2.
[0035] The flat opening 12 is made of flexible PE material and consists of a sleeve 121 and a tapered tube 122; the constricted end of the tapered tube 122 is connected to the sleeve 121. The flat opening 12 is installed inside the ton container 1, with the sleeve 121 facing upwards. During installation, part of the sleeve 121 is pulled out of the inlet pipe 2, forming a U-shape with the opening facing downwards by turning it outwards, which is then fitted onto the inlet pipe 2 and covers the cuff 4.
[0036] An inner plug 6 is inserted into the inlet pipe 2. The inner plug 6 consists of a T-shaped plug body 62 and a pressure ring 61, with the pressure ring 61 protruding outward. The plug body 62 is inserted into the inlet pipe 2, and the pressure ring 61 abuts against the upper end of the inlet pipe 2 to achieve installation limitation, and to make the cuff 4 and sleeve 121 inside the inlet pipe 2 clamped between the plug body 62 and the inner wall of the inlet pipe 2, and the cuff 4 and sleeve 121 at the upper end of the inlet pipe 2 clamped between the pressure ring 61 and the end of the sleeve 121.
[0037] A sealing ring 7 is also fitted onto the plug body 62, and the sealing ring 7 is positioned against the pressure ring 61, thus achieving a sealed connection between the pressure ring 61 and the inlet pipe 2. Figure 8As shown, the connection between the plug body 62 and the outer wall of the compression ring 61 is provided with a recessed limiting groove 63 for clamping the sealing ring 7, so as to improve the positional stability of the sealing ring 7 and keep the sealing performance stable.
[0038] The inlet pipe 2 is also threadedly connected with an upper flange 9. The upper flange 9 is provided with an axial through hole, and the top of the through hole is provided with an inwardly protruding annular pressing plate 91. The lower end surface of the pressing plate 91 abuts against the upper end surface of the compression ring 61; when the upper flange 9 is locked and fixed, the pressing plate 91 exerts downward pressure on the compression ring 61, so that the sealing ring 7 deforms to achieve sealing, and the sleeve 4 at the upper end of the inlet pipe 2, the sleeve 121 and the compression ring 61 are tightly fixed.
[0039] The side wall of the lower end of the upper flange 9 is connected with a positioning ring 92 which is fixed by fusion. The positioning ring 92 is provided with a plurality of rotationally symmetrical positioning holes 93; the upper side of the ton barrel 1 is provided with a positioning block 11 clamping the positioning holes 93. When the installation of the upper flange 9 is completed, the positioning block 11 is clamped through the positioning holes 93 to limit the upper flange 9, so as to avoid self-rotation of the upper flange 9 under the action of vibration or incorrect external force, thereby preventing loosening.
[0040] The material of the positioning ring 92 is selected to be flexible rubber, so that when the upper flange 9 needs to be disassembled, the positioning ring 92 is first lifted upward to move away from the positioning block 11, so as to avoid being blocked by the positioning block 11 during disassembly of the upper flange 9.
[0041] The outer wall of the upper flange 9 is provided with external threads and is threadedly connected with a barrel cover 8 which plugs the through hole in the upper flange 9 to prevent air from entering the inner liner bag 3. A sealing gasket 10 is further arranged between the inner side of the barrel cover 8 and the upper side of the upper flange 9, and the barrel cover 8 exerts pressure on the sealing gasket 10 when locked to deform the sealing gasket 10 to improve the sealing performance.
[0042] When draining, if there is no space for downward drainage on site, the liquid in the inner liner bag 3 needs to be extracted from the inlet, and the barrel cover 8 is removed. The distance between the liquid extraction pipe and the inner wall of the upper flange 9 is large, and a large amount of air is likely to enter the ton barrel 1 to cause the liquid material to deteriorate, so Figure 7 As shown, the barrel cover 8 is further provided with a downwardly extending connecting sleeve 82, and the connecting sleeve 82 is provided with a threaded hole 81 inside for inserting the liquid extraction pipe to extract the liquid in the inner liner bag 3; the threaded hole 81 is gap-fitted with the liquid extraction pipe. When the ton barrel 1 is not used for liquid extraction, the threaded hole 81 is plugged with a plug 13 threadedly connected to the threaded hole 81. The upper end surface of the plug 13 is provided with two symmetrically arranged semicircular grooves, and the straight edges of the grooves are adjacent to each other to facilitate the application of force by fingers in sequence to screw the plug.
[0043] When the inner liner bag 3 needs to be filled with liquid material, the conical part is pulled out upward from the ton barrel 1 and unfolded to the shape of a funnel, at this time the flat mouth 12 covers the inner plug 6, and the falling liquid falls into the inner liner bag 3 along the flat mouth 12, and the splashing liquid generated during filling is blocked by the conical tube 122 and only contacts the inner wall of the flat mouth 12, so that the liquid material does not fly out of the inlet pipe 2 during filling.
[0044] When the liquid material is filled, the conical part is wound into a roll and placed in the ton barrel 1, so that when the liquid in the inner liner bag 3 is shaken during transportation, it only contacts the flat mouth 12.
[0045] Compared with the prior art, the beneficial effects of the embodiment are: 1, the sleeve 4 and the part of the sleeve 121 located in the inlet pipe 2 are limited by the inner plug 6, so that they are kept in contact with the inner wall of the inlet pipe 2, and the structure is more stable; 2, the setting of the compression ring 61 makes the sleeve 4 and the part of the sleeve 121 located at the upper end of the inlet pipe 2 fixed; 3, the barrel cover 8 is threadedly connected with the inlet pipe 2, so that the part of the sleeve 4 and the sleeve 121 in contact with the outer wall of the inlet pipe 2 is locked between the inner thread of the barrel cover 8 and the outer thread of the inlet pipe 2, and the position of the sleeve 4 and the sleeve 121 is more stable; therefore, when the inner liner bag 3 is impacted by the filling liquid, the sleeve 4 and the sleeve 121 can still keep the position stable, so that the inner liner bag 3 does not collapse.
[0046] Based on the above ideal embodiments according to the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the contents in the specification, and must be determined according to the scope of the claims.
