Description

Technical Field

[0001] The present invention relates to the technical field of ton barrels, and specifically to an anti-overflow inner liner bag ton barrel and its installation method. Background Art

[0002] Ton barrels are widely used in the storage and transportation of liquid materials due to their large capacity, convenience in transportation and stacking, environmental protection and recyclability, durability and safety.

[0003] When different materials are replaced in the ton barrel, the ton barrel needs to be cleaned first to avoid cross-contamination between the residues and the new materials, which may affect the quality of the product. The waste water generated during the cleaning process will pollute the environment and needs to be purified before discharge. This not only involves a long process but also high costs.

[0004] Based on the above problems, Chinese Patent CN216334207U discloses a container inner liner for a container that can be assembled with an inner liner bag, including a main body of the inner liner container. An inner liner bag is arranged inside it. The inner liner container main body is provided with a feed inlet, and the inlet of the inner liner bag is installed at the feed inlet and fixed by a feed inlet flange and a sealing cover.

[0005] During filling with the above structure, the liquid material flowing downward will splash, easily fly out from the feed inlet. When it falls on the outer wall of the ton barrel, the ton barrel needs to be cleaned; when it falls on the feed inlet flange, it will contaminate the feed inlet flange; when it falls outside the ton barrel, it will pollute the environment.

[0006] Therefore, how to overcome the above defects has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0007] To solve the technical problems in the background art, the present invention discloses an anti-overflow inner liner bag ton barrel and its installation method.

[0008] The present invention provides an anti-overflow inner liner bag ton barrel, including a ton barrel and an inner liner bag disposed inside. An inlet pipe extending upward is provided on the upper side of the ton barrel; the inner liner bag is provided with a cuff connected to the inlet pipe. The liquid material is filled into the inner liner bag through the cuff. The cuff forms a U-shape with an opening downward by turning outwards, covering the inner and outer walls of the inlet pipe;

[0009] An elastic rubber ring is sleeved outside the cuff;

[0010] The cuff is connected to a flexible flat opening. The upper end of the flat opening also forms a U-shape with an opening downward by turning outwards and sleeved on the cuff;

[0011] An inner plug is inserted into the inlet pipe. A raised pressing plate is provided at the upper end of the inner plug, abutting against the upper end face of the inlet pipe;

[0012] The parts of the cuff and the spreading opening located inside and at the top of the inlet pipe are arranged between the inner plug and the inlet pipe;

[0013] The inlet pipe is provided with external threads and is threadedly connected to an upper flange to tightly press and fix the inner plug;

[0014] The upper flange is provided with external threads and is threadedly connected to a barrel cover;

[0015] During filling, the lower part of the spreading opening is turned up and lifted to a position higher than the inlet pipe;

[0016] After filling is completed, the turned-up and lifted part of the spreading opening is blocked and placed inside the ton barrel.

[0017] The specific structure of the spreading opening is as follows: The spreading opening is composed of a straight sleeve and a flared retaining pipe; when the spreading opening is installed, the sleeve forms a U shape with the opening facing downwards; during filling, the retaining pipe is lifted upwards and forms a funnel shape; after filling is completed, the retaining pipe is wound into a roll shape and placed inside the ton barrel.

[0018] With the above settings, when filling liquid materials into the inner lining bag, the blocking part is unfolded upwards to form a funnel shape to block the splashing liquid, so that the splashing liquid will only adhere to the inner wall of the spreading opening and will not fly out of the outside of the blocking part; when the filling of the liquid materials is completed, the blocking part is blocked and stuffed into the ton barrel to isolate the barrel cover from the liquid materials, so that when the materials in the inner lining bag shake, they will only contact the spreading opening; thus, when the liquid materials splash during filling and when they shake during transportation after filling, they will only come into contact with the spreading opening. When the materials in the ton barrel need to be replaced, a new inner lining bag and spreading opening can be replaced.

[0019] Since the upper flange is likely to rotate under vibration, resulting in loosening, based on this, a further improvement is that: a raised positioning plate is provided on the upper side of the ton barrel; a positioning ring extends radially from the upper flange, and positioning holes are provided on the positioning ring for clamping the positioning plate.

[0020] After the installation of the inner lining bag is completed, it is necessary to inflate the inner lining bag so that the outer wall of the inner lining bag fits against the inner wall of the ton barrel to improve the position and structural stability of the inner lining bag. Since the inner lining bag is located inside the ton barrel, it is difficult to determine whether the inner lining bag fits against the inner wall of the ton barrel. Based on this, a further improvement is that: an identification band is provided on the top surface of the inner lining bag, and the color of the identification band is configured such that when the top surface fits against the inner wall of the ton barrel, the identification band can be observed through the ton barrel, and the inherent color of the identification band can be observed.

[0021] When the inner lining bag drains liquid, due to its flexibility, there will be liquid remaining in the inner lining bag and it is difficult to drain. Based on this, a further improvement is as follows: The side of the inner lining bag with an outlet is set as the front side; the sides connected to the left and right ends of the front side are respectively set as the left side and the right side; the side opposite to the front side is set as the rear side; the sides connected to the upper and lower ends of the front side are respectively set as the top side and the bottom side; a first insertion ring is provided at the connection of the front side, the right side and the bottom side; a second insertion ring is provided at the connection of the rear side, the right side and the bottom side; a third insertion ring is provided at the connection of the rear side, the left side and the bottom side; a fourth insertion ring is provided at the connection of the front side, the left side and the bottom side; one end of a drawstring is fixed to the first insertion ring, and the other end sequentially passes through the second insertion ring and the third insertion ring and is fixed to the fourth insertion ring; the part of the drawstring between the second insertion ring and the third insertion ring extends upward along the rear side. With this setting, when the part of the drawstring between the second insertion ring and the third insertion ring is grasped and lifted upward, the lower end of the rear side is pulled upward and rises. Under the action of the first insertion ring and the fourth insertion ring, the front side, the left side, the right side and the bottom side tilt upward with the liquid outlet valve as the fulcrum, so that the liquid outlet valve becomes the lowest point of the inner lining bag, and the remaining liquid can be easily drained from the liquid outlet valve.

[0022] The outlet of the inner lining bag and the outlet of the ton barrel have the following two structures. One is: At the lower part of the side of the ton barrel corresponding to the front side, there is an outlet pipe extending horizontally and provided with an external thread; the outlet of the inner lining bag is provided with a first liquid outlet valve, and its inlet end abuts against the end of the outlet pipe; the lower flange is threadedly connected to the outlet pipe, and the inlet end of the first liquid outlet valve is clamped and fixed between the lower flange and the outlet pipe. The other is: At the lower part of the side of the ton barrel corresponding to the front side, there is an outlet pipe extending horizontally and provided with an external thread; the outlet of the inner lining bag is connected with a flexible liquid outlet pipe; the outlet end of the liquid outlet pipe is provided with a radially protruding fixing ring; the liquid outlet pipe passes through the outlet pipe outward, and the fixing ring abuts against the end of the outlet pipe; the second liquid outlet valve is threadedly connected to the outlet pipe, and the fixing ring is pressed and fixed.

[0023] For the first structure mentioned above, when the inner lining bag is taken out, small animals such as mice can easily enter the ton barrel through the outlet pipe, causing damage and pollution to the ton barrel. Therefore, a further design is as follows: The valve body of the first liquid outlet valve is provided with a placement groove opening outward; the sealing plate is circular and is composed of a spliced first sealing plate, second sealing plate, first blocking plate, and second blocking plate; the first blocking plate and the second blocking plate are placed inside the placement groove; the first sealing plate and the second sealing plate are spliced into a circle and sleeved on the valve body of the first liquid outlet valve; when the lower flange is locked, the first sealing plate and the second sealing plate are pressed and fixed. The splicing structure of the sealing plate is as follows: a round hole is provided at the splicing position of the first sealing plate and the second sealing plate; the first blocking plate and the second blocking plate are spliced into a circle, and a sunken card slot is provided on the outer side of its arc, which is clamped to the hole wall of the round hole; the splicing seam of the first blocking plate and the second blocking plate is staggered from the splicing seam of the first sealing plate and the second sealing plate. With such a setting, when the sealing plate is not in use, it can be disassembled and installed on the first liquid outlet valve to avoid loss. When the inner lining bag is taken out of the ton barrel, take out the sealing plate and splice it into a circle; then place the sealing plate at the end of the outlet pipe to cover the outlet end of the outlet pipe, and finally use the lower flange to connect with threads to press and fix the sealing plate.

[0024] The above structure of the sealing plate is also applicable to the installation structure of the outlet of the second inner lining bag and the outlet of the ton barrel. Only the lower flange and the sealing plate need to be used as accessories, and the sealing plate can be a whole round plate.

[0025] For the second structure mentioned above, when draining liquid, the part of the inner lining bag located at the drainage port is likely to enter the second liquid outlet valve and even into the valve core, which will not only block the drainage, but also easily tear the inner lining bag when the second liquid outlet valve is rotated, resulting in leakage. Based on this, a further improvement is that a grille is provided at the inlet of the liquid outlet pipe.

[0026] Since the inner lining bag is flexible, when the fixing ring passes through the outlet pipe, the liquid outlet pipe is prone to being distorted, which may cause the inner lining bag to rupture easily. Based on this, a further improvement is that the fixing ring is connected with a radially protruding indicating piece for judging whether the liquid outlet pipe is distorted. When the liquid outlet pipe is distorted, it will reset a certain amplitude under the action of its restoring force. Rotate the liquid outlet pipe along the reset direction so that the indicating piece rotates to the set position, and the distortion of the liquid outlet pipe can be avoided.

[0027] The present invention also provides an installation method for an anti-overflow inner lining bag ton barrel, including the following steps:

[0028] When the outlet of the inner lining bag is connected with the first liquid outlet valve, perform steps S11a - S12a, and then perform step S2; when the outlet of the inner lining bag is connected with a liquid outlet pipe, perform steps S11b - S15b, and then perform step S2;

[0029] S11a. Insert the folded inner lining bag into the ton barrel through the outlet pipe with the first liquid outlet valve facing outwards.

[0030] S12a. The inlet end of the first liquid outlet valve abuts against the end of the outlet pipe, and the lower flange is threadedly connected to and locked with the outlet pipe.

[0031] S11b. Fix one end of the rope on the liquid outlet pipe, place the other end inside the ton barrel, and use a hook to reach into the ton barrel through the outlet pipe to hook out the other end of the rope.

[0032] S12b. Insert the folded inner lining bag into the ton barrel through the inlet pipe with the liquid outlet pipe facing downwards.

[0033] S13b. Fold the liquid outlet pipe radially twice so that the fixing ring passes through the outlet pipe.

[0034] S14b. Loosen the liquid outlet pipe, let it reset, and make the fixing ring abut against the end of the outlet pipe.

[0035] S15b. Threadedly connect the second liquid outlet valve to the outlet pipe and lock it.

[0036] S2. Pull the cuff out of the inlet pipe, turn it outwards to form a U shape with the opening facing downwards, and sleeved the inlet pipe from top to bottom.

[0037] S3. Sleeve the elastic rubber ring on the cuff and tighten it on the inlet pipe.

[0038] S4. Place the flat opening into the ton barrel from the inlet pipe with the baffle pipe facing downwards.

[0039] S5. Pull the sleeve out of the inlet pipe, turn it outwards to form a U shape with the opening facing downwards, and sleeved the cuff from top to bottom.

[0040] S6. Insert the inner plug into the inlet pipe, and the pressing plate abuts against the upper end face of the inlet pipe.

[0041] S7. Threadedly connect the upper flange to the inlet pipe and lock it. When locking, the positioning hole is snap-fitted with the positioning plate; during the rotation of the upper flange, bend the positioning ring at the positioning plate upwards to keep it disengaged from the positioning plate.

[0042] S8. Pull the baffle pipe upwards from the inlet pipe and cover the air outlet of the blower.

[0043] S9. Open the cock on the upper side of the ton barrel so that the inside and outside of the ton barrel are connected through the exhaust port.

[0044] S10. Start the blower and inflate the inner lining bag until the identification belt can be clearly observed through the ton barrel and no gas is discharged from the exhaust port.

[0045] S11. The cock is threadedly connected to the exhaust port and locked; the barrel cover is threadedly connected to the upper flange and locked.

[0046] With the above settings, the inner lining bag can be quickly and efficiently installed in the ton barrel, and has a good sealing effect, and the structure of the inner lining bag is more stable.

[0047] The beneficial effect of the present invention is that when filling liquid materials into the inner lining bag, the blocking part is unfolded upward to form a funnel shape to block the splashing liquid, so that the splashing liquid will only adhere to the inner wall of the flat opening and will not fly out of the outside of the blocking part; when the filling of the liquid material is completed, the blocking part plug is inserted into the ton barrel to isolate the barrel cover from the liquid material, so that when the material in the inner lining bag shakes, it will only contact the flat opening; thus, when the liquid material splashes during filling and shakes during transportation after filling, it will only contact the flat opening. When it is necessary to replace the material in the ton barrel, a new inner lining bag and flat opening can be replaced. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0074] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present invention in a schematic way, so they only show the components related to the present invention.

[0075] Embodiment 1:

[0076] As Figure 1-8 shown, the present invention discloses an anti-overflow inner lining bag ton barrel, including a ton barrel 1 and an inner lining bag 2 disposed therein. An inlet pipe 101 extending upward and provided with an external thread is connected to the upper side surface of the ton barrel 1. The inner lining bag 2 is provided with a cuff 201 connected to the inlet pipe 101, and liquid materials are filled into the inner lining bag 2 from the cuff 201.

[0077] The specific connection structure between the cuff 201 and the inlet pipe 101 is as follows: the cuff 201 forms a U-shaped opening downward by turning outward, covering the inner and outer walls of the inlet pipe 101; an elastic rubber ring 3 is sleeved outside the cuff 201. The end of the cuff 201 also radially extends with an extended part that fits the upper side surface of the ton barrel 1, and the elastic rubber ring 3 is fixed at the root position of the extended part to improve the connection strength between the elastic rubber ring 3 and the cuff 201 and prevent the elastic rubber ring 3 from detaching from the cuff 201.

[0078] The cuff 201 is connected to a flat opening 4 made of flexible PE material. The flat opening 4 consists of a straight sleeve 401 and a flared retaining tube 402; when the flat opening 4 is installed, the sleeve 401 forms a U shape with the opening facing downwards and is sleeved on the cuff 201; during filling, the retaining tube 402 is lifted upwards and forms a funnel shape to block the splashing liquid, so that the splashing liquid only adheres to the inner wall of the flat opening and does not fly out of the blocking part; after filling is completed, the retaining tube 402 is wound into a roll shape and placed in the ton barrel 1 to separate the barrel cover 7 from the liquid material, so that when the material in the inner liner bag 2 shakes, it only contacts the flat opening 4; thus, when the liquid material splashes during filling and shakes during transportation after filling, it only contacts the flat opening 4. When the material in the ton barrel 1 needs to be replaced, a new inner liner bag 2 and flat opening 4 can be replaced.

[0079] An inner plug 5 is inserted into the inlet pipe 101. The inner plug 5 consists of a plug body 502 forming a T shape and a pressing plate 501. The plug body 502 is inserted into the inlet pipe 101, so that the parts of the cuff 201 and the sleeve 401 located inside the inlet pipe 101 are clamped between the plug body 502 and the inner wall of the inlet pipe 101. The pressing plate 501 protrudes radially and abuts against the end of the inlet end, so that the parts of the cuff 201 and the sleeve 401 located at the upper end of the inlet pipe 101 are clamped between the pressing plate 501 and the upper end of the inlet pipe 101. A circular groove 503 is provided at the connection between the plug body 502 and the pressing plate 501, and a sealing ring 504 is clamped in the groove 503 for the sealed connection between the inner plug 5 and the inlet pipe 101. The groove 503 is used to improve the position stability of the sealing ring 504.

[0080] The inlet pipe 101 is threadedly connected to an upper flange 6. The upper flange 6 is provided with an axially arranged through hole, and a pressing ring extending inwards and located directly above the pressing plate 501 is provided at its upper end. When the upper flange 6 is tightened, the pressing ring presses and fixes the pressing plate 501.

[0081] Two convex positioning plates 102, which are symmetrically arranged relative to the inlet pipe 101, are provided on the upper side of the ton barrel 1. The upper flange 6 radially extends a positioning ring 601, and a positioning hole 602 is provided on the positioning ring 601 for clamping the positioning plate 102. The positioning plate 102 is triangular, and its top has a rounded transition. When the positioning hole 602 clamps the positioning plate 102, the length of the positioning plate 102 located in the positioning hole 602 gradually increases for guiding, so that it is convenient for the positioning hole 602 to sleeve the positioning plate 102. When the upper flange 6 is tightened and the positioning hole 602 clamps the positioning plate 102, it can prevent the upper flange 6 from rotating automatically and loosening under vibration.

[0082] The upper flange 6 is provided with an external thread and is threadedly connected to a barrel cover 7. When the barrel cover 7 is tightened, the through hole on the upper flange 6 is blocked to prevent external air from entering the inner liner bag 2. A sealing gasket 14 is also provided on the upper end surface of the upper flange 6, which deforms under the action of the tightening of the barrel cover 7 to improve the sealing performance.

[0083] At the middle position of the barrel cover 7, a sleeve 701 also vertically extends downward. The sleeve 701 is provided with internal threads penetrating through both ends. A plug 15 is threadedly connected to the upper end of the sleeve 701. When there is not enough space for downward liquid drainage on-site, the plug 15 can be opened, and the liquid extraction pipe is inserted into the bottom of the inner lining bag 2 from the sleeve 701 for liquid extraction.

[0084] As Figure 9-15 shown, at the lower part of the side surface of the ton barrel 1 corresponding to the front side surface 204, an outlet pipe 103 extending horizontally and provided with external threads is provided; the outlet of the inner lining bag 2 is provided with a first liquid outlet valve 8, and the inlet end of the first liquid outlet valve 8 is fixedly installed at the outlet of the inner lining bag 2 by means of hot welding. The inlet end of the first liquid outlet valve 8 is provided with an annular and radially protruding fixing plate, and the fixing plate abuts against the end of the outlet pipe 103. The lower flange 9 is threadedly connected to the outlet pipe 103, and the fixing plate of the first liquid outlet valve 8 is clamped and fixed between the lower flange 9 and the outlet pipe 103.

[0085] Since when the inner lining bag 2 is taken out, small animals such as mice can easily enter the ton barrel 1 from the outlet pipe 103, causing damage and pollution to the ton barrel 1, the valve body of the first liquid outlet valve 8 is provided with a placement groove 801 opening outward; the blocking plate 10 is circular and is composed of a spliced first sealing plate 1001, a second sealing plate 1002, a first blocking plate 1003, and a second blocking plate 1004; the first blocking plate 1003 and the second blocking plate 1004 are placed inside the placement groove 801; the first sealing plate 1001 and the second sealing plate 1002 are spliced into a circle and sleeved on the valve body of the first liquid outlet valve 8; when the lower flange 9 is locked, the first sealing plate 1001 and the second sealing plate 1002 are pressed and fixed. The splicing structure of the blocking plate 10 is: a circular hole 1005 is provided at the splicing position of the first sealing plate 1001 and the second sealing plate 1002; the first blocking plate 1003 and the second blocking plate 1004 are spliced into a circle, and a concave card slot 503 is provided on the outer arc thereof, which is clamped to the hole wall of the circular hole 1005; the splicing seam of the first blocking plate 1003 and the second blocking plate 1004 is staggered from the splicing seam of the first sealing plate 1001 and the second sealing plate 1002. With such a setting, when the blocking plate 10 is not in use, it is disassembled and installed on the first liquid outlet valve 8, which can avoid loss. When the inner lining bag 2 is taken out of the ton barrel 1, the blocking plate 10 is taken out and spliced into a circle; then the blocking plate 10 is placed at the end of the outlet pipe 103 to cover the outlet end of the outlet pipe 103, and finally the lower flange 9 is threadedly connected to press and fix the blocking plate 10.

[0086] When the inner lining bag 2 drains liquid, due to its flexibility, there will be residual liquid in the inner lining bag 2, which is difficult to drain. Therefore, as Figure 21 and Figure 22As shown in the figure, the side of the inner lining bag 2 where the outlet is provided is set as the front side 204; the sides connected to the left and right ends of the front side 204 are respectively set as the left side 205 and the right side 206; the side opposite to the front side 204 is set as the rear side 207; the sides connected to the upper and lower ends of the front side 204 are respectively set as the top side 202 and the lower side 209; a first insertion ring 210 is provided at the connection of the front side 204, the right side 206 and the lower side 209; a second insertion ring 211 is provided at the connection of the rear side 207, the right side 206 and the lower side 209; a third insertion ring 212 is provided at the connection of the rear side 207, the left side 205 and the lower side 209; a fourth insertion ring 213 is provided at the connection of the front side 204, the left side 205 and the lower side 209; one end of the drawstring 16 is fixed to the first insertion ring 210, and the other end sequentially passes through the second insertion ring 211 and the third insertion ring 212 and is fixed to the fourth insertion ring 213; the part of the drawstring 16 between the second insertion ring 211 and the third insertion ring 212 extends upward along the rear side 207. With such a setting, when the part of the drawstring 16 between the second insertion ring 211 and the third insertion ring 212 is grasped and lifted upward, the lower end of the rear side 207 is pulled upward and rises, and the front side 204, the left side 205, the right side 206 and the lower side 209 are tilted upward with the liquid outlet valve as the fulcrum under the action of the first insertion ring 210 and the fourth insertion ring 213, so that the liquid outlet valve becomes the lowest point of the inner lining bag 2, and the remaining liquid can be easily discharged from the liquid outlet valve.

[0087] After the inner lining bag 2 is installed, it is necessary to inflate it so that the outer wall of the inner lining bag 2 fits against the inner wall of the ton barrel 1 to improve the structural stability of the inner lining bag 2. Since the inner lining bag 2 is located inside the ton barrel 1, it is difficult to determine whether the inner lining bag 2 is in complete contact with the inner wall of the ton barrel 1. Therefore, as Figure 24 shown, four symmetrically arranged identification bands 203 are provided on the top side 202 of the inner lining bag 2, and the color of the identification bands 203 is configured such that when the top side 202 is in contact with the inner wall of the ton barrel 1, the identification bands 203 can be observed through the ton barrel 1. In this embodiment, the color of the identification bands 203 is red. At the same time, two symmetrically arranged exhaust ports 104 are also provided on the upper side of the ton barrel 1, and a plug 13 is threadedly connected to the exhaust ports 104 to achieve sealing. When the inner lining bag 2 is inflated, the plug 13 is opened, which can not only quickly discharge the air between the inner lining bag 2 and the ton barrel 1, but also determine that the inflation of the inner lining bag 2 is completed when there is no gas discharged from the exhaust ports 104.

[0088] As Figure 23 shown, when the inner lining bag 2 is installed, the part of the drawstring 16 between the second insertion ring 211 and the third insertion ring 212 is placed in the adjacent exhaust port 104, so as to facilitate the worker to lift the drawstring 16 upward.

[0090] Compared with the first embodiment, the differences are as follows: As Figure 16-20 shown, at the lower part of the side of the ton barrel 1 corresponding to the front side 204, there is an outlet pipe 103 that extends horizontally and is provided with external threads; the outlet of the inner lining bag 2 is connected with a flexible liquid outlet pipe 11 made of PE material; at the outlet end of the liquid outlet pipe 11, there is a radially protruding fixing ring 1101, and at the inlet end, there is a radially protruding connecting ring 1104, which is fixedly installed at the outlet of the inner lining bag 2 by means of hot welding. The liquid outlet pipe 11 passes outwards from the outlet pipe 103, and the fixing ring 1101 abuts against the end of the outlet pipe 103; the second liquid outlet valve 12 is threadedly connected to the outlet pipe 103 to press and fix the fixing ring 1101.

[0091] During liquid drainage, the part of the inner lining bag 2 located at the liquid drainage port is likely to enter the second liquid outlet valve 12 and even into the valve core, which will not only block the liquid drainage, but also easily tear the inner lining bag 2 when the second liquid outlet valve 12 is rotated, resulting in leakage. Therefore, a grille 1102 is provided at the inlet of the liquid outlet pipe 11 to block the inner lining bag 2.

[0092] Since the inner lining bag 2 is flexible, when the fixing ring 1101 passes through the outlet pipe 103, the liquid outlet pipe 11 is likely to be distorted, resulting in the easy rupture of the inner lining bag 2. Therefore, the following design is made: The fixing ring 1101 is connected with a radially protruding indicating piece 1103 for judging whether the liquid outlet pipe 11 is distorted. When the liquid outlet pipe 11 is distorted, it will reset a certain amplitude under the action of its restoring force. Rotate the liquid outlet pipe 11 along the reset direction so that the indicating piece 1103 rotates to the set position, and the distortion of the liquid outlet pipe 11 can be avoided.

[0093] The lower flange 9 and the plugging plate 10 in this embodiment are used as accessories, and the plugging plate 10 can be a whole round plate.

[0094] Embodiment Three:

[0095] The present invention also discloses an installation method for an anti-overflow inner lining bag ton barrel, including the following steps:

[0096] When the outlet of the inner lining bag 2 is connected with the first liquid outlet valve 8, steps S11a - S12a are executed, and then step S2 is executed; when the outlet of the inner lining bag 2 is connected with the liquid outlet pipe 11, steps S11b - S15b are executed, and then step S2 is executed;
