Description

Technical Field

[0001] This utility model relates to the field of separation and purification equipment, and in particular to a separation and purification equipment for the processing of 4-hydroxybiphenyl. Background Technology

[0002] 4-Hydroxybiphenyl, also known as p-hydroxybiphenyl, is a white needle-like or flaky crystal with a melting point of 164-165℃, a boiling point of 305-308℃, and a flash point of 165℃. It is readily soluble in alcohols and ethers, and also soluble in alkaline solutions. It can sublimate. Currently, most preparation methods involve recovering it from the distillation residue of phenol produced by the sulfonation process. Its main uses are as an intermediate in dyes, resins, and rubber. Red and green photosensitive pigments synthesized from this product are one of the main raw materials for color films, and it is also used as an analytical reagent.

[0003] Existing technologies have the following problems:

[0004] Patent application CN202221302148.7 discloses a separation and purification device for processing 4-hydroxybiphenyl. The stirring structure of this separation device is fixed, and it is impossible to flexibly adjust the stirring force and range according to the properties of the solution, such as viscosity and concentration. For example, for high viscosity solutions, the fixed-angle stirring rod is difficult to mix deeply, resulting in low extraction efficiency. On the other hand, for low viscosity solutions, turbulence may be generated due to excessive stirring force, which affects the separation effect. Secondly, after the separation process, the inner wall of the device and the stirring components are prone to material residue. Traditional cleaning methods require manual disassembly of components, which is cumbersome and incomplete, and may lead to cross-contamination, affecting the quality of subsequent batches of products and causing inconvenience in cleaning.

[0005] To address these shortcomings, we proposed a separation and purification device for the processing of 4-hydroxybiphenyl. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a separation and purification device for the processing of 4-hydroxybiphenyl.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a separation and purification device for processing 4-hydroxybiphenyl, comprising a mixing chamber, wherein a rotating column is disposed through the interior of the mixing chamber, and a stirring blade is hinged to the outer wall of the rotating column; a threaded rod is rotatably connected inside the rotating column, and a threaded block is fitted on the surface of the threaded rod; a connecting rod is hinged between the threaded block and the stirring blade; a handle is provided at one end of the threaded rod; a guide groove is formed on the outer wall of the rotating column; the connecting rod is slidably connected to the guide groove; a driven gear is fixedly installed at the upper end of the outer wall of the rotating column; a drive motor and a booster pump are fixedly installed on the top surface of the mixing chamber; a drive gear is installed at the output end of the drive motor, and the drive gear meshes with the driven gear; a cleaning pipe is suspended on the inner top surface of the mixing chamber, and a cleaning nozzle is fixedly installed on the surface of the cleaning pipe; the water outlet of the booster pump is connected to the cleaning pipe through a water pipe.

[0008] Preferably, a feed pipe and a discharge pipe are fixedly installed on the top and bottom surfaces of the mixing tank, respectively, and a valve is fixedly installed on the surface of the discharge pipe.

[0009] Preferably, a control switch is fixedly installed on the outer wall of the mixing tank, and the control switch is electrically connected to the drive motor and the booster pump through wires.

[0010] Preferably, the stirring blades are provided in multiples, and the multiple stirring blades are equidistantly distributed on the surface of the rotating column.

[0011] Preferably, the rotating column has a hollow structure.

[0012] Preferably, the cleaning nozzles are provided in multiples, and the multiple cleaning nozzles are distributed in a ring array on the surface of the cleaning pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the stirring blade angle can be adjusted by rotating the handle to optimize the stirring effect for different solution characteristics. Adjusting the stirring blade angle to close to 90° increases the contact area between the stirring blade and the solution, enhances the stirring force, promotes the solution to flow over a wide range, and accelerates extraction and separation. Adjusting the stirring blade angle to 30°-45° reduces the generation of turbulence and ensures uniform dispersion of the solute through fine stirring, avoiding component damage caused by excessive stirring. The angle adjustment range of 0°-90° covers a variety of working conditions. Compared with the traditional fixed-angle stirring structure, the separation efficiency is greatly improved.

[0015] 2. After the separation operation is completed in this utility model, there is no need to disassemble the parts. The booster pump is started directly by the control switch. The booster pump delivers clean water to the cleaning nozzle through the cleaning pipe, forming a multi-angle high-pressure water flow to automatically wash the inner wall of the mixing tank, the stirring blades and the residual materials at the bottom. The cleaning wastewater is discharged through the discharge pipe, which reduces the cost of manual cleaning, avoids the contamination of subsequent batches by residual materials, and improves the convenience of operation and the purity of the product.

[0025] Please refer to Figure 1-4 A separation and purification device for processing 4-hydroxybiphenyl includes a mixing chamber 1. A rotating column 3 is installed through the interior of the mixing chamber 1, and a stirring blade 4 is hinged to the outer wall of the rotating column 3. A threaded rod 13 is rotatably connected inside the rotating column 3, and a threaded block 14 is fitted on the surface of the threaded rod 13. A connecting rod 15 is hinged between the threaded block 14 and the stirring blade 4. A handle 12 is provided at one end of the threaded rod 13. A guide groove 16 is opened on the outer wall of the rotating column 3, and the connecting rod 15 is slidably connected to the guide groove 16. A driven gear 11 is fixedly installed on the upper end of the outer wall of the rotating column 3. A drive motor 9 and a booster pump 6 are fixedly installed on the top surface of the mixing chamber 1. A drive gear 10 is installed at the output end of the drive motor 9, and the drive gear 10 meshes with the driven gear 11. A cleaning pipe 7 is suspended on the inner top surface of the mixing chamber 1, and a cleaning nozzle 8 is fixedly installed on the surface of the cleaning pipe 7. The water outlet of the booster pump 6 is connected to the cleaning pipe 7 through a water pipe.

[0026] In operation, the 4-hydroxybiphenyl solution to be separated is first injected into the mixing tank 1 through the feed pipe 2. Depending on the solution properties such as viscosity and concentration, the handle 12 is manually rotated. For high-viscosity solutions, the handle 12 is rotated clockwise, causing the threaded rod 13 to rotate. The threaded block 14 moves axially along the threaded rod 13, pushing the stirring blade 4 around the hinge point via the connecting rod 15. This gradually increases the angle of the stirring blade 4 to nearly 90°, increasing the contact area between the stirring blade 4 and the solution, enhancing the stirring force, and promoting a wide flow of the solution to accelerate extraction and separation. For low-viscosity solutions, the handle 12 is rotated counterclockwise, causing the threaded block 14 to move and the angle of the stirring blade 4 to decrease to 30°-45°. This reduces the impact force of the stirring blade 4 on the solution, ensuring uniform dispersion of the solute through fine stirring and avoiding turbulence caused by excessive stirring. After angle adjustment, the drive motor 9 is started. The drive gear 10 at its output end drives the driven gear 11 to rotate, thereby driving the rotating column 3 and the stirring blade 4. The system rotates to stir, mix, and extract the solution in the mixing tank 1. After separation, the valve of the discharge pipe 5 is opened to discharge the solution. The residual material settles at the bottom of the mixing tank 1. The booster pump 6 is started by the control switch 17. External clean water is pressurized by the booster pump 6 and delivered to the cleaning pipe 7. High-pressure water is then sprayed onto the inner wall, stirring blades 4, and bottom of the mixing tank 1 through the ring array of cleaning nozzles 8. The residual material is rinsed from multiple angles. The cleaning wastewater is discharged through the discharge pipe 5. No manual disassembly of parts is required, which improves cleaning efficiency and convenience.

[0027] In this implementation plan: the top and bottom surfaces of the mixing tank 1 are respectively fixedly installed with a feed pipe 2 and a discharge pipe 5, and a valve is fixedly installed on the surface of the discharge pipe 5.

[0028] Specifically, to control the input and output of the solution, a control switch 17 is fixed on the outer wall of the mixing tank 1 and electrically connected to the drive motor 9 and the booster pump 6 through wires to realize centralized control of equipment start-up, shutdown and function switching.

[0029] In this embodiment: a control switch 17 is fixedly installed on the outer wall of the mixing tank 1, and the control switch 17 is electrically connected to the drive motor 9 and the booster pump 6 through wires.

[0030] Specifically, the common circuit connection structure will not be elaborated on here.

[0031] In this embodiment, multiple stirring blades 4 are provided, and the multiple stirring blades 4 are equidistantly distributed on the surface of the rotating column 3.

[0032] Specifically, to improve the separation and purification effect and efficiency of 4-hydroxybiphenyl.

[0033] In this implementation scheme: the rotating column 3 is a hollow structure.

[0034] Specifically, the rotating column 3 has a hollow structure with a threaded rod 13 rotatably connected inside. Multiple equally spaced stirring blades 4 are hinged to the outer wall. One end of the threaded rod 13 extends to the outside of the rotating column 3 and fixes the handle 12, while the other end is fixed inside the rotating column 3 by a bearing. The threaded block 14 is threadedly engaged with the threaded rod 13, and its side is hinged to the back of the stirring blades 4 by a connecting rod 15. A guide groove 16 is opened on the outer wall of the rotating column 3, and the end of the connecting rod 15 is embedded in the guide groove 16 and slides to ensure the stability and guidance of the stirring blades 4 when adjusting the angle.

[0035] In this embodiment, multiple cleaning nozzles 8 are provided, and the multiple cleaning nozzles 8 are distributed in a ring array on the surface of the cleaning pipe 7.

[0036] Specifically, the outlet of the booster pump 6 is connected to the cleaning pipe 7 via a water pipe. When the booster pump 6 is started, clean water is sprayed through the cleaning nozzle 8 to form a high-pressure water flow, covering the inner wall of the mixing tank 1, the surface of the stirring blade 4, and the bottom area, achieving thorough cleaning.

[0037] Working Principle: In operation, the 4-hydroxybiphenyl solution to be separated is first injected into the mixing tank 1 through the feed pipe 2. Depending on the solution properties such as viscosity and concentration, the handle 12 is manually rotated. For high-viscosity solutions, rotating the handle 12 clockwise rotates the threaded rod 13, causing the threaded block 14 to move axially along the threaded rod 13. This, in turn, pushes the stirring blade 4 around the hinge point via the connecting rod 15, gradually increasing the angle of the stirring blade 4 to nearly 90°. This increases the contact area between the stirring blade 4 and the solution, enhancing the stirring force and promoting a wide flow of the solution, accelerating extraction and separation. For low-viscosity solutions, rotating the handle 12 counterclockwise moves the threaded block 14, reducing the angle of the stirring blade 4 to 30°-45°. This reduces the impact force of the stirring blade 4 on the solution, ensuring uniform dispersion of the solute through fine stirring and preventing turbulence caused by excessive stirring. After angle adjustment, the drive motor 9 is started. The output gear 10 drives the driven gear 11, thereby driving the rotating column 3 and the stirring blade 4 to rotate, thus rotating the mixing tank 1. The solution inside is stirred, mixed, and extracted. After separation, the valve of the discharge pipe 5 is opened to discharge the solution. The residual material is deposited at the bottom of the mixing tank 1. The booster pump 6 is started by the control switch 17. External clean water is pressurized by the booster pump 6 and sent to the cleaning pipe 7. High-pressure water is then sprayed onto the inner wall of the mixing tank 1, the stirring blades 4 and the bottom through the ring array of cleaning nozzles 8. The residual material is washed from multiple angles. The cleaning wastewater is discharged through the discharge pipe 5. No manual disassembly of parts is required, which improves cleaning efficiency and convenience.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
