Description

Technical Field

[0001] The utility model relates to the technical field of plastic barrels, in particular to a double-layer plastic barrel with a built-in liquid buffer dumping structure. Background Art

[0002] Plastic barrels are mostly used for the storage and transportation of various liquids. They have good characteristics for special dangerous goods packaging. They are not easy to break, rust-free, light, and have excellent oil and strong corrosion resistance. They are mostly used for dangerous goods packaging that require heat preservation, moisture resistance, pressure resistance, and corrosion resistance. Plastic barrels are mostly made of polyethylene, polypropylene, polyester and other plastics through blow molding, injection molding, suction molding, and rotational molding. They are mostly used to hold liquids in the chemical, pesticide, pharmaceutical, food and other industries.

[0003] When existing plastic barrels are filled with liquid, in order to facilitate the discharge of the liquid, a drain valve is often provided at the bottom of the barrel. However, the pressure at the bottom of the barrel is often relatively high and may exceed the bearing pressure of the drain valve, thereby causing the drain valve to leak. If the stored liquid is corrosive, it may gradually erode the material of the valve and also cause its sealing to decrease. At the same time, when the plastic barrel is impacted by the outside world, the liquid in the barrel is prone to shaking, thereby reducing the stability of the plastic barrel. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a double-layer plastic barrel with a built-in liquid buffer dumping structure, which solves the problem that the drain valve is prone to leakage and the liquid in the barrel is prone to shaking when the plastic barrel is impacted by the outside, thereby reducing the stability of the plastic barrel.

[0005] To achieve the above purpose, the utility model is implemented by the following technical solutions: comprising an outer barrel body, an inner barrel body is fixedly installed at the bottom of the inner wall of the outer barrel body, a barrel cover is fixedly installed at the top of the inner barrel body, a group of buffer components are arranged between the outer barrel body and the inner barrel body to buffer external impact force, two floating components are arranged on the inner wall of the inner barrel body to reduce the shaking of the liquid in the barrel, and a liquid outlet component is arranged at the top of the barrel cover to discharge the liquid in the barrel;

[0006] The liquid outlet assembly includes a U-shaped tube, the outer wall of the U-shaped tube is fixedly sleeved with a fixed tube sleeve, the fixed tube sleeve is fixedly connected to the barrel cover, one end of the U-shaped tube passes through the top of the barrel cover and is inserted into the bottom end of the inner barrel body, the outer wall of the U-shaped tube is fixedly connected with a connecting tube, the top of the connecting tube is fixedly connected with a top cover, a sliding rod is movably inserted at the top of the top cover, the output shaft of the sliding rod passes through the top of the top cover and is fixedly installed with a movable piston, the movable piston is fitted with the inner wall of the top cover, and a pull plate is fixedly installed at the top of the sliding rod.

[0007] Preferably, a water outlet valve is provided at the other end of the U-shaped tube, a connecting hose is fixedly connected to the other end of the U-shaped tube, a liquid outlet pipe is fixedly connected to the output end of the connecting hose, and a manual valve is provided at the output end of the connecting hose.

[0008] Preferably, the buffer assembly comprises an outer mounting plate, a group of spring shock absorbers are fixedly mounted on the outer wall of the outer mounting plate, and an inner mounting plate is fixedly mounted on one end of the outer wall of the group of spring shock absorbers.

[0009] Preferably, the floating assembly includes a vertical shell, an outer wall of the vertical shell is penetrated with a slide groove, an inner wall of the vertical shell is provided with a floating ball, an outer wall of the floating ball is fixedly installed with a floating connecting rod, one end of the outer wall of the floating connecting rod is fixedly installed with a floating circular plate, and a group of through holes are penetrated at the top of the floating circular plate.

[0010] Preferably, the diameter of the floating ball is larger than the width of the chute, and the diameter of the floating connecting rod is smaller than the width of the chute.

[0011] Preferably, the two vertical shells are fixedly connected to the inner wall of the inner barrel body, a group of the outer mounting plates are fixedly connected to the outer barrel body, a group of the inner mounting plates are fixedly connected to the inner barrel body, the top end of the barrel cover is fixedly connected to a liquid inlet pipe, a pipe cover is provided at the top end of the liquid inlet pipe, and a clamping plate is fixedly installed on the outer wall of the outer barrel body.

[0012] Beneficial Effects

[0013] The utility model provides a double-layer plastic bucket with a built-in liquid buffer dumping structure. Compared with the prior art, it has the following beneficial effects:

[0014] (1) In the double-layer plastic barrel with a built-in liquid buffer dumping structure, when it is necessary to drain the liquid from the inner barrel body, the water outlet valve is first closed to keep the U-shaped tube sealed, and then the pull plate is pulled. The pull plate drives the slide rod and the movable piston to move upward in the top cover. When the movable piston is pulled upward, a pressure difference is generated. Under the action of the pressure difference, the liquid in the inner barrel body is pressed into the other end of the U-shaped tube. At this time, the water outlet valve is opened to generate a siphon effect, so that the liquid can be discharged continuously. Then, the liquid in the U-shaped tube is discharged from the liquid outlet pipe through the connecting hose, and the liquid in the inner barrel body can be drained. Since no drain valve is provided at the bottom of the barrel body, leakage of the liquid in the barrel through the drain valve is avoided, thereby solving the problem mentioned in the background technology.

[0015] (2) The double-layer plastic barrel with a built-in liquid buffer dumping structure is provided with an outer barrel body and an inner barrel body, and multiple groups of spring shock absorbers are arranged between the outer barrel body and the inner barrel body. When subjected to external impact, the outer barrel body can reduce the damage caused by the impact to the plastic barrel itself, thereby extending the service life of the plastic barrel, while the spring shock absorber can absorb and buffer the impact force, thereby greatly reducing the shaking amplitude of the liquid in the inner plastic barrel. At the same time, a floating component is arranged in the inner barrel body, and the floating circular plate will float on the liquid surface. When the liquid surface shakes, the floating circular plate will move with the flow of the liquid, which will hinder the rapid flow and large-scale shaking of the liquid. Thereby, the intensity of the shaking is reduced to a certain extent, and a floating connecting rod and a floating ball are provided, so that the floating circular plate can be movably inserted inside the vertical shell, which can give the floating circular plate a certain degree of freedom and enable the floating circular plate to rotate in some directions. The rotating floating circular plate can adjust the angle in time to resist and buffer the impact forces in the best posture, thereby more effectively reducing the shaking. At the same time, the floating ball is inside the vertical shell, so that the floating circular plate is subject to additional constraints and guidance to prevent the floating circular plate from irregular deviation, so that the floating circular plate can remain in a relatively stable position and continuously suppress the shaking of the liquid.

The floating circular plate 46 will float on the liquid surface. When the liquid surface shakes, the floating circular plate 46 will move with the flow of the liquid, which will hinder the rapid flow and large-scale shaking of the liquid, thereby reducing the intensity of the shaking to a certain extent. A group of through holes 47 are penetrated at the top of the floating circular plate 46. The setting of the through holes 47 can reduce the impact of the liquid surface shaking on the floating circular plate 46.

The diameter of the floating connecting rod 45 is smaller than the width of the chute 42, which can enable the floating connecting rod 45 to move in the chute 42, so that the floating circular plate 46 has a certain degree of freedom, so that the floating circular plate 46 can rotate in some directions. The rotating floating circular plate 46 can adjust the angle in time to resist and buffer these impact forces in the best posture, thereby more effectively reducing shaking.

[0030] The two vertical shells 41 are fixedly connected to the inner wall of the inner barrel body 2, a group of outer mounting plates 31 are fixedly connected to the outer barrel body 1, a group of inner mounting plates 33 are fixedly connected to the inner barrel body 2, the top of the barrel cover 8 is fixedly connected to the liquid inlet pipe 9, and the top of the liquid inlet pipe 9 is provided with a pipe cover 7.

[0032] During operation, an outer barrel body 1 and an inner barrel body 2 are provided, and a plurality of spring shock absorbers 32 are provided between the two. When subjected to external impact, the outer barrel body 1 can reduce the damage to the plastic barrel itself caused by the impact, thereby extending the service life of the plastic barrel, and the spring shock absorber 32 can absorb and buffer the impact force, thereby greatly reducing the shaking amplitude of the liquid in the internal plastic barrel. At the same time, a floating component 4 is provided in the inner barrel body 2, and a floating circular plate 46 floats on the liquid surface. When the liquid surface shakes, the floating circular plate 46 moves with the flow of the liquid, which will hinder the rapid flow and large-scale shaking of the liquid, thereby reducing the intensity of the shaking to a certain extent. A floating connecting rod 45 and a floating ball 43 are provided, so that the floating circular plate 46 is movably inserted in the interior of the vertical shell 41, which can give the floating circular plate 46 a certain degree of freedom, so that the floating circular plate 46 can rotate in some directions, and the rotating floating circular plate 46 can adjust the angle in time to resist and buffer these impact forces in the best posture, thereby more effectively reducing the shaking, and at the same time the floating circular plate The ball 43 is in the vertical shell 41, so that the floating circular plate 46 is subject to additional constraints and guidance, which prevents the floating circular plate 46 from irregularly deflecting, so that the floating circular plate 46 can be kept in a relatively stable position, and the sloshing of the liquid is continuously suppressed. When the liquid in the inner barrel body 2 needs to be discharged, the water outlet valve 58 is closed first, so that the U-shaped tube 51 remains sealed, and then the pull plate 55 is pulled, and the pull plate 55 drives the slide rod 56 and the movable piston 57 to move upward in the top cover 54. When the movable piston 57 is pulled upward, Due to the pressure difference, under the action of the pressure difference, the liquid in the inner barrel body 2 is pressed into the other end of the U-shaped tube 51 outside the barrel. At this time, when the water outlet valve 58 is opened, a siphon effect will be generated, allowing the liquid to be discharged continuously. Then, the liquid in the U-shaped tube 51 is discharged from the liquid outlet pipe 511 through the connecting hose 59, and the liquid in the inner barrel body 2 can be discharged. The manual valve 510 can control the drainage efficiency of the liquid outlet pipe 511. Since the drain valve is not set at the bottom of the barrel body, the liquid in the barrel is prevented from leaking through the drain valve.
