Description

Technical Field

[0001] This utility model relates to the field of liquid diversion, and in particular to a multi-channel diversion liquid filling device. Background Technology

[0002] Engineered equipment that efficiently and precisely dispenses liquids from one or a few sources to multiple destinations. It is widely used in automated scenarios requiring batch or continuous liquid filling, replenishment, or dispensing, and is an important tool for improving production efficiency and ensuring process consistency. Its complexity ranges from simple manual multi-way valves to highly automated precision filling systems.

[0003] In related technologies, a typical multi-channel distribution system involves multiple independent distribution channels located inside or outside the housing. These channels start from a common inlet, branch out inside the housing, and each extends and connects to a corresponding outlet, thereby enabling the simultaneous and orderly distribution of liquid from the same source to multiple target branches.

[0004] However, this method has obvious drawbacks, as it cannot filter the liquid that has passed through the diversion device. Utility Model Content

[0005] The main purpose of this invention is to provide a multi-channel diversion liquid filling device to solve the problem of liquid diversion.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a multi-channel diversion filling device, comprising: The flow divider housing includes a main flow chamber and multiple flow divider holes that are interconnected. A first filter element is fitted in the main flow chamber, and the flow divider holes extend to the outside of the flow divider housing. The sealing cap is detachably connected to the upper end of the diversion housing. The sealing cap is equipped with a main connecting pipe, and the main connecting pipe contains a second filter element. The upper end of the main connecting pipe is used to connect to the main flow pipeline, and the lower end is threaded to the main flow cavity. Multiple diverter pipes are provided at equal intervals around the perimeter. Each diverter pipe is fixedly connected to a diverter hole and is used to connect to a diverter pipeline.

[0007] In the preferred embodiment, the diversion housing is further provided with a pressure relief hole, and the bottom of the diversion housing is provided with a base for fixing. The main flow cavity extends axially into the diversion housing. Multiple diversion holes are circumferentially distributed on the diversion housing. The pressure relief hole and the main flow cavity are interconnected. The outer walls of the diversion housing and the sealing cover are provided with cold insulation and heat insulation material.

[0008] In the preferred embodiment, the sealing cover includes a connecting cover and a connecting hole. The connecting cover is fixed inside the sealing cover. The connecting hole is concentrically formed on both the sealing cover and the connecting cover, and the connecting hole and the main flow cavity are set at the same center.

[0009] In the preferred embodiment, a first connecting body is provided on the outside of the main connecting pipe, and a first gasket is provided on the inner wall of the first connecting body. The first connecting body is fixedly connected to the top of the sealing cover.

[0010] In the preferred embodiment, each diversion pipe is provided with a second connecting body on its outer side, and the inner wall of the second connecting body is provided with a second gasket for sealing connection with the diversion pipe. The second connecting body is fixedly connected to the outer wall of the diversion housing.

[0011] In the preferred embodiment, a magnetic screen is provided at the bottom of the main connecting pipe, and the magnetic screen is used to support the second filter element.

[0012] In the preferred embodiment, a pressure relief assembly is provided at the pressure relief hole.

[0013] In the preferred embodiment, the connecting cover is threaded to the inner wall of the diversion housing, and the main connecting pipe is threaded to the main flow cavity, so that the sealing cover and the connecting cover seal the upper end of the diversion housing.

[0014] In the preferred embodiment, a third gasket is provided on the inner wall of the sealing cap, and a fourth gasket is provided at the bottom of the connecting cap.

[0015] In the preferred embodiment, the pressure relief assembly includes a safety valve and a pressure gauge mounted on the pressure relief pipe, and the pressure relief pipe is located at the pressure relief hole and fixed to the outer wall of the diversion housing.

[0016] The beneficial effects of this multi-channel diversion liquid filling device are: 1. The first and second filter elements installed in the device can perform multi-stage precision filtration on the flowing liquid. The second filter element is usually used to intercept larger particles of impurities in the liquid, playing a preliminary purification role, while the first filter element further removes finer suspended solids and contaminants, ensuring that the cleanliness of the liquid entering the subsequent system meets the process requirements; 2. When the distributor shell is carrying cryogenic liquids such as liquid oxygen or liquid nitrogen, to prevent a large amount of heat from the external environment from entering the shell through conduction, convection, or radiation, which could lead to premature vaporization of the liquid, increased system pressure, or even safety hazards, a layer of high-efficiency cold-insulating material must be wrapped around the outer surface of the distributor shell and sealing cover. This insulation layer typically uses materials with low thermal conductivity, such as polyurethane foam, vacuum insulation panels, multi-layer composite insulation felt, or foam glass, to minimize heat exchange. 3. Once liquid oxygen comes into contact with hot air or absorbs external heat, it will rapidly undergo a phase change, transforming from a liquid to a gaseous state, causing a sharp expansion in volume and a sudden increase in internal system pressure. To address this risk, the device is equipped with a dedicated pressure relief component (such as a safety valve or rupture disc) on the distribution housing, which is directly connected to the main internal chamber. When the pressure inside the chamber exceeds a preset safety threshold due to liquid oxygen vaporization or other reasons, the pressure relief component will automatically open, quickly releasing the overpressured gas and preventing the housing from deforming or rupturing due to overpressure.

[0020] Furthermore, the diversion housing 1 is a cylinder, and extends downward from the top to form a connecting cavity. A main flow cavity 101 extends downward from the middle of the connecting cavity. The diameter of the connecting cavity is larger than the diameter of the main flow cavity 101. Multiple diversion holes 102 are evenly spaced along the circumference of the side wall of the main flow cavity 101. The main flow cavity 101 and the diversion holes 102 are interconnected, and the diversion holes 102 extend to the outside of the diversion housing 1. The upper ends of the connecting cavity and the main flow cavity 101 are threaded and used to connect the sealing cap 2 and the main connecting pipe 3. The first filter element 6 is sleeved in the main flow cavity 101. The sealing cap 2 is detachably connected to the upper end of the distribution housing 1, making it easy to remove for cleaning or replacement of the first filter element 6 during use. A main connecting pipe 3 is fixedly connected to the middle of the sealing cap 2, extending into the distribution housing 1. The upper end of the main connecting pipe 3 is used to connect to the main flow pipeline, and the lower end is threaded to the main flow cavity 101. The liquid to be transported is then transported through the main flow pipeline to the main flow cavity 101 in the distribution housing 1. Multiple distribution pipes 4 are evenly spaced along the circumference of the distribution housing 1 and are fixedly connected to the distribution holes 102. Each distribution pipe 4 has threads on its outer wall and is threaded to the distribution pipeline. The first filter element 6 and the second filter element 7 can filter impurities in the pipeline, preventing impurities from flowing rapidly with the liquid in the pipeline, colliding with the pipeline wall, generating sparks, and causing liquid oxygen combustion, which could lead to a hazard.

[0021] The diversion housing 1 is also provided with a pressure relief hole 103, and a base 104 for fixing is provided at the bottom of the diversion housing 1. The main flow cavity 101 extends axially into the diversion housing 1. Multiple diversion holes 102 are circumferentially distributed on the diversion housing 1. The pressure relief hole 103 and the main flow cavity 101 are interconnected. The outer walls of the diversion housing 1 and the sealing cover 2 are provided with cold insulation and heat insulation materials.

[0022] Furthermore, the pressure relief hole 103 is located at the lower end of the outer wall of the diversion housing 1, and the pressure relief hole 103 extends through the main flow chamber 101. The base 104 at the bottom of the diversion housing 1 is used for fixing, and the diversion housing 1 can be fixed to other structures to prevent displacement during use. The diversion hole 102 is used to divert the liquid entering the main flow chamber 101. Cold and heat insulation materials are installed on the outer walls of the diversion housing 1 and the sealing cover 2 to insulate the diversion housing 1 from external heat.

[0023] The sealing cover 2 includes a connecting cover 201 and a connecting hole 202. The connecting cover 201 is fixed inside the sealing cover 2. The connecting hole 202 is concentrically opened on the sealing cover 2 and the connecting cover 201, and the connecting hole 202 and the main flow cavity 101 are arranged at the same center.

[0024] Furthermore, the sealing cap 2 includes a connecting cap 201 and a connecting hole 202. The diameter of the sealing cap 2 is larger than that of the connecting cap 201, and a gap is provided between the connecting cap 201 and the sealing cap 2, which are concentrically arranged. The connecting hole 202 is concentrically opened on the sealing cap 2 and the connecting cap 201, and the connecting hole 202 is correspondingly arranged with the main flow cavity 101, which is beneficial for the main connecting pipe 3 to be connected to the main flow cavity 101.

[0025] The main connecting pipe 3 is provided with a first connecting body 12 on the outside, and the inner wall of the first connecting body 12 is provided with a first gasket 8. The first connecting body 12 is fixedly connected to the top of the sealing cover 2.

[0026] Furthermore, the inner diameter of the first connecting body 12 is larger than the diameter of the main connecting pipe 3, and there is a gap between them and they are concentrically arranged. The inner wall of the first connecting body 12 is fixedly connected to the first washer 8. The main flow pipe is connected between the first connecting body 12 and the main connecting pipe 3. When the inner wall of the main flow pipe is threaded to the main connecting pipe 3, the outer wall of the main flow pipe is fitted onto the first washer 8 when it is screwed into the main connecting pipe 3, so as to achieve the purpose of sealing.

[0027] Each diversion pipe 4 is provided with a second connecting body 13 on its outer side, and the inner wall of the second connecting body 13 is provided with a second gasket 9 for sealing connection with the diversion pipe. The second connecting body 13 is fixedly connected to the outer wall of the diversion housing 1.

[0028] Furthermore, the inner diameter of the second connecting body 13 is larger than that of the diversion pipe 4, and there is a gap between them and they are concentrically arranged. A second gasket 9 is fixedly connected to the inner wall of the second connecting body 13. The diversion pipe is connected between the diversion pipe 4 and the second connecting body 13. The diversion pipe is threaded to the diversion pipe 4, and when the diversion pipe is screwed into the diversion pipe 4, its outer wall is fitted onto the second gasket 9 to achieve a seal and prevent leakage when conveying liquid.

[0029] The bottom of the main connecting pipe 3 is equipped with a magnetic screen 5, which is used to support the second filter element 7.

[0030] Furthermore, iron filings will be generated during the liquid transport process, so the magnetic screen 5 is set up to adsorb ferromagnetic impurities in the liquid flow, and can also be used to support the second filter element 7.

[0031] A pressure relief assembly 14 is provided at the pressure relief hole 103.

[0032] Furthermore, a pressure relief assembly 14 is fixed at the position of the pressure relief hole 103. Since the liquid oxygen is diverted in a closed space, and the liquid oxygen will vaporize and generate pressure after coming into contact with heat, a pressure relief assembly 14 is provided on the diversion housing 1. The pressure relief assembly 14 is used to detect the pressure value change in the diversion housing 1 in a timely manner and release the pressure in the diversion housing 1 in a timely manner.

[0033] The connecting cover 201 is threaded to the inner wall of the diversion housing 1, and the main connecting pipe 3 is threaded to the main flow cavity 101, so that the sealing cover 2 and the connecting cover 201 seal the upper end of the diversion housing 1.

[0034] Furthermore, the outer wall of the connecting cover 201 is threaded and threaded into the connecting cavity provided in the diverter housing 1. The upper and lower ends of the main connecting pipe 3 are both threaded, with the lower end threaded into the main flow cavity 101. A gap is provided between the connecting cover 201 and the sealing cover 2, and they are concentrically arranged.

[0035] The inner wall of the sealing cover 2 is provided with a third gasket 10, and the bottom of the connecting cover 201 is provided with a fourth gasket 11.

[0036] Furthermore, when the connecting cover 201 and the sealing cover 2 are screwed into the diversion housing 1, a third washer 10 is provided on the inner wall of the sealing cover 2, which abuts against the outer wall of the diversion housing 1 and plays a sealing and anti-overflow role. The top of the connecting cover 201 is fixedly connected to the sealing cover 2, and a fourth washer 11 is provided at the bottom. After the connecting cover 201 is tightened, the fourth washer 11 is held against the bottom surface of the connecting cavity to achieve a sealing and locking effect.

[0037] The pressure relief assembly 14 includes a safety valve 1401 and a pressure gauge 1402 disposed on the pressure relief pipe 1403. The pressure relief pipe 1403 is disposed at the pressure relief hole 103 and fixed to the outer wall of the diversion housing 1.

[0038] Furthermore, when the liquid to be transported in the distribution housing 1 is a low-temperature liquid, the hot air outside the distribution housing 1 infiltrates and reacts with the cold liquid inside, causing water droplets to form on the outer wall of the distribution housing 1, while the liquid inside the distribution housing 1 undergoes a liquid-to-vapor reaction. Therefore, a pressure relief hole 103 is provided at the lower end of the main flow chamber 101. The pressure relief hole 103 is connected to a safety valve 1401 through a pressure relief pipe 1403. When the pressure in the distribution housing 1 reaches a certain value, the safety valve 1401 will automatically relieve the internal pressure, and the pressure gauge 1402 can monitor the pressure change in the distribution housing 1. Once liquid oxygen comes into contact with hot air or absorbs external heat, it will rapidly undergo a phase change, transforming from a liquid to a gas, and its volume will expand rapidly, causing a sudden increase in the internal pressure of the system. Therefore, a dedicated pressure relief component 14 (such as a safety valve or rupture disc) is provided on the distribution housing 1 and is directly connected to the internal main flow chamber 101. When the pressure inside the cavity exceeds the preset safety threshold due to liquid oxygenation or other reasons, the pressure relief component 14 will automatically open to quickly release the overpressured gas and prevent the shell from deforming or rupturing due to overpressure.

[0039] The implementation principle of this embodiment is as follows: The diversion shell 1 is a cylinder, and a layer of cold-insulating and heat-insulating material can be provided on the outer wall of the diversion shell 1 to keep the liquid oxygen in the diversion shell 1 cold and also to isolate the heat outside the diversion shell 1. The diversion shell 1 extends downward from the top to form a connecting cavity, and a main flow cavity 101 extends downward from the middle of the connecting cavity. The main flow cavity 101 is provided with multiple diversion holes 102 around its circumference. When the sealing cover 2 is sealed and connected to the diversion shell 1, the main connecting pipe 3 is connected to the sealing cover 2, and the diversion pipes 2 are respectively connected to the diversion holes 102 around their circumference, when the liquid oxygen enters the main flow cavity 101 from the main connecting pipe 3, it is then diverted through the diversion pipes 4. The main flow cavity 101 is fitted with a first filter element 6, and the main connecting pipe 3 is fitted with a second filter element 7. When the liquid oxygen is diverted in the pipe, there will be some impurities. The first filter element 6 and the second filter element 7 can filter out the impurities of the liquid oxygen. This application uses low-temperature resistant metal materials, such as stainless steel, and the gaskets are made of low-temperature resistant plastic materials, such as polytetrafluoroethylene. The first filter element 6 and the second filter element 7 can perform multi-stage precision filtration on the flowing liquid. The second filter element 7 is usually used to intercept larger particles of impurities in the liquid, playing a preliminary purification role, while the first filter element 6 further removes finer suspended solids and contaminants, ensuring that the cleanliness of the liquid entering the subsequent system meets the process requirements.
