Description

Technical Field

[0001] This utility model relates to the technical field of liquid material storage equipment, specifically to a leak-proof liquid material storage tank. Background Technology

[0002] Liquid material storage tanks are core equipment in industries such as chemical, food, and pharmaceutical for storing raw materials, finished products, or intermediate products. Their main function is to prevent liquid leakage through a sealed structure, thereby avoiding safety accidents, environmental pollution, or material loss.

[0003] Existing storage containers generally suffer from the following problems: First, their sealing structures are often simplistic (such as the lid being directly pressed into the body or sealed with threads and a single sealing ring), making them susceptible to seal failure due to transportation vibrations and internal pressure fluctuations. Second, the bottom discharge port design is often inadequate, leading to eddies during liquid discharge, resulting in material residue and low discharge efficiency. Third, the container body lacks reinforcement, making it prone to deformation under prolonged pressure. These problems reduce the reliability, practicality, and safety of the storage containers. Summary of the Invention

[0004] The purpose of this invention is to provide a leak-proof liquid material storage tank that is reliably sealed, has high discharge efficiency, high strength, and good stability, thereby solving the problems of leakage, discharge residue, and insufficient strength of existing storage tanks.

[0005] The present invention provides a leak-proof liquid material storage tank, comprising a lid, a body, and a discharge valve. The lid and body are connected by multiple snap fasteners. The top opening of the body has an upwardly extending annular flange. The lower surface of the lid has an annular groove that matches the annular flange. A first sealing ring is embedded in the bottom of the annular groove, and a second sealing ring that presses against the inner wall of the annular flange is embedded in the inner side of the groove. Thus, when the lid and body are fastened together, a double sealing structure is formed with the annular flange in both radial and axial directions. The bottom inner side of the barrel is provided with a guide plate that is inclined towards the inlet of the discharge valve, and the lowest point of the guide plate is connected to the inlet of the discharge valve. At least three circumferentially distributed support feet are fixed to the outer bottom of the barrel body, and the lower surface of the support feet is lower than the lowest point of the discharge valve.

[0006] As a preferred technical solution of this utility model, an anti-vortex baffle is fixed on the flow guide base plate. The anti-vortex baffle is one or more upright plate-shaped structures located directly above the discharge valve inlet.

[0007] As a preferred technical solution of this utility model, the anti-vortex baffle is a support plate structure parallel to the inlet direction of the discharge valve, and its center position is aligned with the inlet center axis of the discharge valve. When multiple anti-vortex baffles are provided, the multiple anti-vortex baffles are arranged parallel to each other.

[0008] As a preferred technical solution of this utility model, the barrel body is made of metal material, and its outer wall is provided with a plurality of outwardly protruding reinforcing ribs.

[0009] As a preferred embodiment of this utility model, the barrel body is circumferentially fitted with and fixed with two reinforcing hoops on the outside of the reinforcing ribs, and the two reinforcing hoops are respectively located at the upper and lower parts of the barrel body.

[0010] In a preferred embodiment of this invention, the discharge valve is a butterfly valve, a ball valve, or a diaphragm valve. The discharge valve is connected to the outlet at the bottom of the barrel via a flange, and a sealing gasket is sandwiched between the flange and the barrel. A corresponding fitting groove is provided on the barrel at the flange, and the flange and the fitting groove are fixedly connected by bolts, with the sealing gasket located between the flange and the fitting groove.

[0011] As a preferred embodiment of this utility model, the first sealing ring is made of fluororubber or silicone rubber and has an O-shaped cross-section; the second sealing ring is made of polytetrafluoroethylene and has a rectangular cross-section.

[0012] As a preferred embodiment of this utility model, the support foot is an L-shaped frame structure with anti-slip pads welded to its bottom.

[0013] As a preferred technical solution of this utility model, the upper part of the side wall of the barrel is also provided with a transparent liquid level observation window and a high and low liquid level alarm interface, which facilitates monitoring the liquid level in the barrel and prevents overflow and leakage caused by overfilling.

[0014] The advantages of this utility model compared with the prior art are as follows: 1. Improved sealing reliability: The dual sealing structure (axial + radial) effectively resists pressure fluctuations and vibrations, preventing leakage; the two types of sealing rings are adapted to the requirements of chemical corrosion resistance (fluororubber / silicone rubber) and wear resistance (PTFE), respectively, extending service life.

[0015] 2. Improved discharge efficiency and reduced residue: The inclined guide plate directs the liquid flow to the discharge valve, and the anti-vortex baffle disrupts the vortex flow, making discharge smoother and reducing residue by more than 80%.

[0016] 3. Enhanced strength and stability of the barrel: The combination of reinforcing ribs and reinforcing hoops improves the barrel's compressive rigidity and prevents deformation; the support feet are lower than the lowest point of the discharge valve, and combined with anti-slip pads, ensure that the barrel remains stable and does not shift during discharge.

[0017] 4. Convenient liquid level monitoring: The transparent observation window displays the liquid level intuitively, and the alarm interface can be connected to a sensor to prevent overfilling and overflow, thus avoiding safety hazards. Attached Figure Description

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0025] As per the instruction manual Figure 1-2As shown, a leak-proof liquid material storage tank includes a lid 1, a tank body 2, and a discharge valve 3, wherein the lid 1 and the tank body 2 are connected by multiple fasteners 4.

[0026] In this utility model, the barrel body 2 is made of metal material, and its outer wall is provided with a plurality of outwardly protruding reinforcing ribs 12. Two reinforcing hoops 13 are circumferentially sleeved and fixed on the barrel body 2 outside the reinforcing ribs 12, and the two reinforcing hoops 13 are respectively located at the upper and lower parts of the barrel body 2. The reinforcing ribs 12 are provided with corresponding slots at the reinforcing hoops 13 to prevent the reinforcing hoops 13 from shifting during the fixing process.

[0027] In this utility model, a transparent liquid level observation window 17 and a high and low liquid level alarm interface 18 are also provided on the upper part of the side wall of the barrel 2, so as to facilitate monitoring of the liquid level in the barrel and prevent overflow and leakage caused by overfilling.

[0028] In this utility model, the bottom inner side of the barrel 2 is provided with a guide plate 9 that is inclined towards the inlet direction of the discharge valve 3. The lowest point of the guide plate 9 is connected to the inlet of the discharge valve 3. An anti-vortex baffle 11 is fixed on the guide plate 9. The anti-vortex baffle 11 is one or more upright plate-shaped structures located directly above the inlet of the discharge valve 3. The anti-vortex baffle 11 is a support plate structure parallel to the inlet direction of the discharge valve 3, and its center position is aligned with the central axis of the inlet of the discharge valve 3. Multiple anti-vortex baffles 11 are arranged parallel to each other.

[0029] In this utility model, at least three circumferentially distributed support feet 10 are fixed on the outer bottom of the barrel body 2. The lower surface of the support feet 10 is lower than the lowest point of the discharge valve 3. The support feet 10 have an L-shaped frame structure and anti-slip pads 16 are welded to their bottom.

[0030] As per the instruction manual Figure 3 As shown, the top opening of the barrel body 2 is provided with an upwardly extending annular flange 5, and the lower surface of the barrel lid 1 is provided with an annular pressing groove 6 that matches the annular flange 5; a first sealing ring 7 is embedded in the bottom of the annular pressing groove 6, and a second sealing ring 8 that presses against the inner side wall of the annular flange 5 is embedded in the inner side wall of the groove, so that when the barrel lid 1 and the barrel body 2 are fastened together, they form a double sealing structure in the radial and axial directions with the annular flange 5.

[0031] In this invention, the first sealing ring 7 is made of fluororubber or silicone rubber and has an O-shaped cross-section; the second sealing ring 8 is made of polytetrafluoroethylene and has a rectangular cross-section.

[0032] As per the instruction manual Figure 4As shown, the discharge valve 3 is a ball valve. The discharge valve 3 is connected to the outlet at the bottom of the barrel 2 through the flange 14. A sealing gasket 15 is sandwiched between the flange 14 and the barrel 2. A corresponding fitting groove is provided on the barrel 2 at the connection of the flange 14. The flange 14 and the fitting groove are fixedly connected by bolts, and the sealing gasket 15 is located between the flange 14 and the fitting groove.

[0033] Workflow 1. Fasten the lid 1 to the body 2 with the buckle 4. Embed the annular flange 5 into the groove. The first sealing ring 7 achieves axial sealing, and the second sealing ring 8 is pressed against the inner wall of the flange to achieve radial sealing.

[0034] 2. During storage, check the liquid level through the observation window. When the liquid level reaches a high level, the sensor connected to the alarm interface will trigger an alarm and stop feeding.

[0035] 3. Open the butterfly valve, and the liquid flows along the guide plate 9 to the discharge valve 3. The anti-vortex baffle 11 breaks the vortex. After the discharge is completed, close the valve. The support feet 10 and the anti-slip pads ensure the stability of the barrel 2.

[0036] 1. The lid 1 and the body 2 are rigidly connected by a snap fastener 4. The annular flange 5 and the pressure groove form a closed chamber. The first sealing ring 7 fills the axial gap and prevents liquid from leaking along the contact surface between the lid 1 and the body 2. The second sealing ring 8 is interference-fitted with the inner wall of the annular flange 5 to block the radial leakage channel and achieve "axial + radial" double sealing.

[0037] 2. The inclined angle of the guide plate 9 uses gravity to guide the liquid to flow towards the discharge valve 3, reducing the residue at the bottom; the anti-vortex baffle 11 is perpendicular to the liquid flow direction, which breaks the formation of vortex (vortex originates from the centrifugal force when the liquid is discharged), so that the liquid enters the discharge valve 3 in a straight line, improving the discharge efficiency and avoiding material splashing.

[0038] 3. The outer side of the barrel 2 is reinforced with axial stiffeners 12 to disperse internal pressure and prevent the barrel 2 from bulging due to liquid weight or external impact. The stiffeners 13 are fitted around the outside of the stiffeners 12 to restrain the deformation of the stiffeners and enhance the overall rigidity. The bottom of the barrel 2 is designed with support feet 10 to keep the center of gravity of the barrel 2 below the lowest point of the discharge valve 3, so that the barrel 2 will not tilt due to liquid flow during discharge. The anti-slip pad increases the friction coefficient with the ground and prevents slippage.

[0039] The transparent observation window on one side of the 4 tank body 2 is made of high-transmittance PVC material, which can directly read the liquid level height; the high and low liquid level alarm interface 18 is connected to a liquid level sensor (such as an inductive type). When the liquid level exceeds the threshold, the sensor outputs an electrical signal to trigger the alarm, reminding the operator to intervene and prevent overflow.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
