Description

Technical Field

[0001] This utility model relates to a flow equalization rapid liquid dispenser, specifically an integrated rapid equalization liquid dispenser based on a three-stage gradient, belonging to the field of liquid dispenser technology. Background Technology

[0002] Liquid separators are specialized laboratory equipment used for the precise distribution or separation of liquids. Based on their working principle and application scenarios, they can be divided into the following two categories: bottle-mouth liquid separators are devices that achieve precise quantitative transfer of liquids through a piston-driven mechanism; glass liquid separators are instruments that separate immiscible liquids based on differences in liquid density and the siphon principle.

[0003] Current liquid dispensers have the following drawbacks: 1. Traditional laminar flow liquid dispensers generate vortex effects when the flow rate is >5L / min, resulting in a liquid dispensing error >15%; 2. Multi-stage liquid dispensing structures require the assembly of multiple components, increasing processing costs by more than 50%; 3. A drainage channel length >200mm results in a liquid dispensing time >30 seconds. To address these issues, we provide an integrated, rapid, and equalizing liquid dispenser based on a three-stage gradient to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an integrated rapid equalization dispenser based on a three-level gradient to solve the above-mentioned problems, thereby addressing the issues of dispensing errors and long dispensing times in the prior art.

[0005] This utility model is achieved through the following technical solution: an integrated rapid equalization dispenser based on a three-level gradient.

[0006] It includes a cylindrical steady-flow inlet pipe, the top end of which is fixedly connected to a buffer steady-flow chamber, the top end of which is fixedly connected to a pressure equalization liquid distribution chamber, the top end of which is fixedly connected to an equal-division output chamber, the surface of which is fixedly connected to a laminar flow outlet pipe, and the middle part of the pressure equalization liquid distribution chamber has three sets of circumferentially arranged channels.

[0007] Preferably, the ratio of the number of holes in each ring of the three sets of channels is 24:28:36, the hole diameter increases by 1.2, 1.5, and 2.0 mm, and the channel axis inclination angle decreases by 30°, 25°, and 20°. Through the three sets of channels, the buffer flow stabilizing chamber is connected to the equally divided output chamber, and the conveyed fluid is decelerated and pressure divided.

[0008] Preferably, the buffer flow stabilization chamber is funnel-shaped with an expansion angle of 15°±1°, and the inner wall of the cylindrical flow stabilization inlet pipe is provided with a spiral guide groove. Through the spiral guide groove inside the cylindrical flow stabilization inlet pipe, the turbulent fluid is converted into quasi-laminar flow, reducing the impact force of the fluid.

[0009] Preferably, a central guide column is provided in the middle of the pressure equalization liquid distribution chamber, and the surface of the central guide column is provided with circumferentially arranged micro-pits. The fluid output from the cylindrical steady-flow liquid pipe is guided and dispersed through the central guide column and the micro-pits.

[0010] Preferably, the laminar flow outlet pipes are arranged in a symmetrical manner of six, eight or ten, and multiple laminar flow outlet pipes are arranged equidistantly on the surface of the equally divided output chamber. By setting a laminar flow outlet pipe every 60°, the flow rate and pressure are evenly distributed to ensure that the difference in flow rate at each outlet is <2%.

[0011] This invention provides an integrated rapid equalization dispenser based on a three-stage gradient, which has the following beneficial effects:

[0012] 1. This integrated rapid equalization liquid distributor based on a three-stage gradient uses a cylindrical steady-flow inlet pipe to guide fluid into a buffer flow chamber, where the fluid velocity is reduced. The pressure equalization distribution chamber further smooths the flow, and the equalized output chamber and laminar flow outlet pipe uniformly distribute the fluid, improving the stability and accuracy of the distribution. The channel reduces the impact force on the fluid, preventing pressure differences within the equalized output chamber and enhancing the stability of the distribution. It is suitable for various distribution scenarios, is compact, has low pressure resistance, and provides uniform distribution.

[0013] 2. This integrated rapid equalization distributor based on a three-stage gradient connects the buffer flow stabilization chamber and the equal distribution output chamber through three sets of channels, reducing the speed and pressure of the delivered fluid and improving the stability of the pressure inside the equal distribution output chamber. The spiral guide groove inside the cylindrical steady inlet pipe transforms the turbulent fluid into a quasi-laminar flow, reducing the impact force of the fluid and the influence of the end flow on the distributor. The central guide column and micro-dimples guide and disperse the fluid output from the cylindrical steady inlet pipe, avoiding the water hammer effect caused by excessive fluid velocity and improving the stability of fluid backflow and distribution. By evenly distributing the flow rate and pressure, it ensures that the difference in flow rate at each outlet is <2%. Attached Figure Description

[0022] This utility model provides an integrated rapid equalization dispenser based on a three-level gradient.

[0023] Please see Figure 1 , Figure 2 and Figure 3 The system includes a cylindrical steady-flow inlet pipe 1, with a buffer flow stabilizing chamber 2 fixedly connected to the top of the cylindrical steady-flow inlet pipe 1. A pressure equalization distribution chamber 3 is fixedly connected to the top of the buffer flow stabilizing chamber 2, and an equal distribution output chamber 4 is fixedly connected to the top of the pressure equalization distribution chamber 3. A laminar flow outlet pipe 5 is fixedly connected to the surface of the equal distribution output chamber 4. Fluid flows into the buffer flow stabilizing chamber 2 through the cylindrical steady-flow inlet pipe 1, where the fluid velocity is reduced. The pressure equalization distribution chamber 3 further smooths the fluid flow. The equal distribution output chamber 4 and the laminar flow outlet pipe 5 uniformly distribute the fluid, improving the stability and accuracy of fluid distribution.

[0024] The buffer flow stabilizing chamber 2 is shaped like a trumpet with an expansion angle of 15°±1°. The inner wall of the buffer cylindrical flow stabilizing inlet pipe 1 is provided with a spiral guide groove. Through the spiral guide groove inside the cylindrical flow stabilizing inlet pipe 1, the turbulent fluid is converted into a quasi-laminar flow, reducing the impact force of the fluid and reducing the influence of the end flow on the distributor.

[0025] The laminar flow outlet pipes 5 are arranged circumferentially at equal intervals on the surface of the equally divided output chamber 4. There can be six, eight or ten laminar flow outlet pipes 5 symmetrically distributed. By arranging the laminar flow outlet pipes 5 at equal intervals, the flow rate and pressure are evenly distributed to ensure that the difference in flow rate at each outlet is <2%.

[0026] Please see Figure 2 and Figure 3 The pressure equalization liquid distribution chamber 3 has three sets of circumferentially arranged channels 301 in the middle. Through the channels 301, the impact force of the fluid is reduced, avoiding pressure difference inside the equal distribution output chamber 4 and improving the stability of fluid distribution.

[0027] The ratio of the number of holes in each ring of the three sets of channels 301 is 24:28:36, with the hole diameter increasing by 1.2, 1.5, and 2.0 mm, and the channel axis inclination angle decreasing by 30°, 25°, and 20°. The first ring has 24 holes: Φ1.2±0.05mm, the second ring has 28 holes: Φ1.5±0.05mm, and the third ring has 36 holes: Φ2.0±0.05mm. Through the three sets of channels 301, the buffer flow stabilizing chamber 2 is connected to the equally divided output chamber 4, and the conveyed fluid is decelerated and pressure divided to improve the stability of the internal pressure of the equally divided output chamber 4.

[0028] The cylindrical steady-flow pipe 1, buffer steady-flow chamber 2, pressure equalization liquid distribution chamber 3, equal-division output chamber 4, and laminar flow outlet pipe 5 are made of ABS-like engineering plastic and 3D printed using SLS process. The wall thickness uniformity error is <0.1mm and the surface roughness Ra≤6.3μm. The SLS process 3D printing makes the device integrally formed, improving the convenience of device production and use.

[0029] Please see Figure 4 A central guide column 302 is provided in the middle of the pressure equalization liquid distribution chamber 3. The surface of the central guide column 302 is provided with circumferentially arranged micro-pits 303. The central guide column 302 and the micro-pits 303 guide and disperse the fluid output from the cylindrical steady inflow pipe 1, avoid the fluid velocity being too fast and forming a water hammer effect, and improve the stability of fluid backflow and liquid distribution.

[0030] SLS technology manufactures objects by importing data from a 3D model into a 3D printer and using a laser beam to scan the powder. SLS, or Selective Laser Sintering 3D Printing, is a revolutionary industrial technology. Its working principle involves importing layer-by-layer data from a 3D model into the 3D printer and using a CO2 laser (a 10.6μm infrared laser) as the energy source. The printer uses micron-sized spherical plastic powder as its building block. Through precise computer control, the laser beam precisely scans the powder surface, causing the plastic powder to sinter or melt and then re-solidify, thus forming solid layers that conform to the cross-section of the model.

[0031] Overall material of the device: ABS-like engineering plastic (flexural strength ≥65MPa, heat distortion temperature 90℃); Process: SLS 3D printing (layer thickness 0.1mm, laser power 30W, scanning speed 2000mm / s); Test data:

[0032]

[0033] ABS engineering plastic, also known as PC+ABS (engineering plastic alloy), is called plastic alloy in the chemical industry. It's named PC+ABS because this material combines the excellent heat and weather resistance, dimensional stability, and impact resistance of PC resin with the excellent processing fluidity of ABS resin. Therefore, it can maintain its superior performance in thin-walled and complex-shaped products, while retaining the moldability of a material composed of plastic and an ester.

[0034] The preferred manufacturing method for this dispenser is 3D printing, but it can also be formed using other methods that enable this structure. Precision casting and other metal and ceramic materials can also be used.

[0035] Working principle: Using existing manufacturing technology, the main body of the distributor is integrally processed and formed. After processing, the device is installed on the distributor equipment. Fluid is input through the cylindrical steady-flow pipe 1 and enters the buffer flow stabilization chamber 2. Through the interaction of the shape of the buffer flow stabilization chamber 2, the central guide column 302 and the micro-dimples 303, the flow rate of the fluid is slowed down. The fluid flows evenly into the equal distribution output chamber 4 through three sets of channels 301, avoiding excessive pressure difference inside the equal distribution output chamber 4 and improving the stability of fluid distribution. The fluid inside the equal distribution output chamber 4 is evenly output through multiple layered flow outlet pipes 5, reducing the fluid distribution time and reducing fluid errors, thereby improving the accuracy and efficiency of fluid distribution.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
