Description

Technical Field

[0001] The utility model belongs to the technical field of industrial processing, in particular to a continuous cavitation reactor. Background Art

[0002] In the production process of chemicals, continuous cavitation reactor plays a vital role as an efficient and versatile equipment. This advanced equipment is widely used in various chemical reactions, especially those that require extreme conditions (such as high temperature and high pressure) to promote reaction rate or achieve specific chemical transformation.

[0003] At present, the traditional continuous cavitation reactor is to let the reaction liquid enter the cavitation chamber from the liquid inlet pipe, the cavitation rotor rotates rapidly, and the pressure in the cavitation rotor's tapered section and throat gradually decreases along the flow direction until the throat outlet. At the throat outlet, the cavitation rotor changes shape suddenly, and the pressure is the lowest at this time. When the pressure is lower than the saturated vapor pressure of the corresponding temperature, a large number of cavitation bubbles appear in the liquid. The collapse of the cavitation bubbles will cause hot spots in the extremely small space around the cavitation bubbles, generating instantaneous high temperature (about 1900-5200K) and high pressure (more than 50MPa), and can form strong shock waves and microjets with a speed of more than 100m / s. This extreme physical and chemical environment can cause a variety of physical and chemical effects, which can enable some reactions that require high temperature and high pressure to proceed. After the liquid enters the gradually expanding section through the throat, as the reaction liquid enters the gradually expanding section through the throat, the pressure gradually rises, and then the reaction liquid will be discharged from the liquid outlet pipe;

[0004] However, when the reaction liquid finally reaches the liquid outlet pipe and is ready to be discharged, the inclination angle of the discharge pipe is too large, which makes it impossible for the reaction liquid in the pipe to be completely discharged. The residual reaction liquid may adhere to the pipe wall or accumulate at the bottom of the pipe, forming dirt or residues that are difficult to remove. What is more serious is that when the reactor continues to operate or conducts the next round of reaction, the undischarged reaction liquid may flow back into the cavitation chamber due to factors such as gravity, vibration or fluid disturbance. This reflux phenomenon will not only reduce the overall efficiency of the reactor, but may also introduce impurities or by-products, affecting the quality and purity of subsequent reactions.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 5As shown, the utility model provides a continuous cavitation reactor, including a base 1, a three-phase asynchronous motor 2 is fixedly installed on the top of the base 1, a coupling 4 is provided at the output end of the three-phase asynchronous motor 2, a main shaft 5 is provided inside the coupling 4, a preheating chamber 6 located on the surface of the main shaft 5 is fixedly installed on the top of the base 1, a cavitation chamber 7 is provided inside the preheating chamber 6, a cavitation rotor 8 located inside the cavitation chamber 7 is fixedly installed on the surface of the main shaft 5, a drain pipe 9 is provided at the right end of the cavitation chamber 7, and a valve 10 is provided on the surface of the drain pipe 9;

[0024] A flow guiding mechanism is arranged at the top of the base 1, and the flow guiding mechanism includes a support block 11, which is fixedly connected to the top of the base 1, and a U-shaped shell 12 located at the bottom end of the drain pipe 9 is fixedly installed on the top of the support block 11, and a hose 13 located inside the U-shaped shell 12 is arranged at the bottom end of the surface of the drain pipe 9, and a valve 14 is arranged on the surface of the hose 13, and a driving assembly 15 is fixedly installed at the rear end of the U-shaped shell 12, and the output end of the driving assembly 15 extends to the inside of the U-shaped shell 12 and is fixedly installed with a rotating disk 16, and a connecting shell 17 is fixedly installed on the surface of the rotating disk 16, and an extrusion wheel 18 is rotatably connected to the inside of the connecting shell 17, and the surface of the extrusion wheel 18 contacts the surface of the hose 13, and a fixing sleeve 30 located on the surface of the hose 13 is arranged at the rear end of the U-shaped shell 12.

[0025] The above scheme is adopted: the operator injects the reaction liquid into the cavitation chamber 7, and then the three-phase asynchronous motor 2 can be driven to rotate the coupling 4, the coupling 4 will drive the main shaft 5 to rotate, and the main shaft 5 will drive the cavitation rotor 8 to rotate rapidly, and then the pressure of the tapered section and the throat in the cavitation rotor 8 will gradually decrease along the flow direction until the throat outlet, and the shape of the cavitation rotor 8 will change at the throat outlet, and then the pressure inside the cavitation chamber 7 is the lowest. When the pressure is lower than the saturated vapor pressure of the corresponding temperature, a large number of cavitation bubbles will appear in the liquid, and when the cavitation bubbles collapse, hot spots will be induced in the extremely small space around the cavitation bubbles, generating instantaneous high temperature, and then the pressure inside the cavitation chamber 7 will gradually increase along the flow direction, and then the valve 10 can be opened, and then the reaction liquid will be discharged from the inside of the drain pipe 9;

[0026] After the reaction liquid is discharged, the valve 2 14 can be opened, and the driving component 15 can be driven to rotate the rotating disk 16, and then the rotating disk 16 will drive the connecting shell 17 to rotate, and the connecting shell 17 will drive the extrusion wheel 18 to rotate. Since the surface of the extrusion wheel 18 is in contact with the surface of the hose 13, when the extrusion wheel 18 rotates, it will squeeze the surface of the hose 13. While squeezing, the pressure inside the hose 13 will decrease. While the pressure inside the hose 13 decreases, the reaction liquid remaining in the drain pipe 9 will be absorbed to prevent the reaction liquid inside the drain pipe 9 from flowing back into the cavitation chamber 7, and then the reaction liquid will be discharged from the hose 13. Finally, by driving the extrusion wheel 18 to rotate and squeeze the hose 13, the reaction liquid remaining in the drain pipe 9 can be cleaned to prevent the reaction liquid from flowing back into the cavitation chamber 7, and the cleaning efficiency inside the drain pipe 9 is improved, the risk of blockage of the drain pipe 9 is reduced, and the smooth progress of subsequent processing is ensured.

[0027] like Figure 3 and Figure 4 As shown, a sealing plate 28 is provided at the front end of the U-shaped shell 12, and the U-shaped shell 12 and the sealing plate 28 are hinged by a hinge chain 29. A handle is provided at the bottom end of the front side of the sealing plate 28, and a support plate 21 is fixedly installed at the top of the base 1. The left end of the support plate 21 is rotatably connected to a protective roller 22 located on the surface of the hose 13.

[0028] The above scheme is adopted: through the design of the sealing plate 28 and the hinge chain 29, since the U-shaped shell 12 and the sealing plate 28 are hinged by the hinge chain 29, the U-shaped shell 12 can be held by holding the handle and then rotating the hinge chain 29, and then the operator can maintain the components inside the U-shaped shell 12. Through the design of the support plate 21 and the protective roller 22, when installing the hose 13, the hose 13 can be wrapped around the surface of the protective roller 22, thereby ensuring the smooth flow of the reaction liquid and protecting the surface of the hose 13.

[0029] like Figure 4 As shown, a fixed shell 23 is fixedly installed on the right end of the base 1, a fixed groove 24 is opened on the front side of the fixed shell 23, a collecting groove 25 is arranged inside the fixed groove 24, and a plug hole 26 is opened on the right side of the fixed shell 23 and the collecting groove 25, and a plug rod 27 is inserted into the plug hole 26.

[0030] The above scheme is adopted: through the design of the fixed shell 23, the fixed groove 24 and the collecting groove 25, when the reaction liquid is discharged from the inside of the hose 13, the reaction liquid will flow to the inside of the collecting groove 25, and then the collecting groove 25 can collect the reaction liquid, thereby reducing the processing cost. Through the design of the socket 26 and the plug rod 27, when it is necessary to take out the reaction liquid in the collecting groove 25, the plug rod 27 can be pulled out from the inside of the socket 26, and then the limit of the collecting groove 25 will be cancelled, and then the collecting groove 25 can be pulled out from the inside of the fixed groove 24, and then the reaction liquid in the collecting groove 25 can be processed. After the processing is completed, the collecting groove 25 can be inserted into the inside of the fixed groove 24 again, and then the two sockets 26 will overlap, and then the plug rod 27 can be inserted into the inside of the socket 26, and then the collecting groove 25 can be limited to avoid the position of the collecting groove 25 being offset when the collecting groove 25 collects the reaction liquid, causing the reaction liquid to flow to the outside of the collecting groove 25.

[0031] like Figure 4 and Figure 5 As shown, a guide plate 3 located at the top of the collecting tank 25 is fixedly installed at the right end of the base 1. The guide plate 3 is inclined, and a connecting plate 19 is provided on the opposite side of the fixing sleeve 30. Threaded holes 20 are provided on the rear side of the U-shaped shell 12 and the surface of the connecting plate 19.

[0032] The above scheme is adopted: through the design of the guide plate 3, when the reaction liquid is discharged from the inside of the hose 13, it will flow to the top of the guide plate 3. Since the guide plate 3 is designed to be inclined, the reaction liquid can be guided to the inside of the collecting tank 25. Through the design of the connecting plate 19 and the threaded hole 20, the fixing sleeve 30 can be put on the surface of the hose 13, and then the threaded hole 20 on the surface of the connecting plate 19 is aligned with the threaded hole 20 on the rear side of the inside of the U-shaped shell 12. Then, the fixing bolt can be inserted into the inside of the threaded hole 20, and then the fixing sleeve 30 can be fixed inside the U-shaped shell 12, and then the fixing sleeve 30 can limit the hose 13.

[0033] The working principle and use process of this utility model:

[0034] First, the operator can inject the reaction liquid into the cavitation chamber 7, and then drive the three-phase asynchronous motor 2 to rotate the coupling 4 and the main shaft 5, and the main shaft 5 will drive the cavitation rotor 8 to rotate, and the tapered section and throat pressure in the cavitation rotor 8 will gradually decrease along the flow direction until the throat outlet, and the shape of the cavitation rotor 8 will change at the throat outlet, and a large number of cavitation bubbles will appear in the liquid. When the cavitation bubbles collapse, hot spots will be caused in the extremely small space around the cavitation bubbles, generating instantaneous high temperature, and then the pressure inside the cavitation chamber 7 will gradually increase along the flow direction, and then the valve 10 can be opened, and then the reaction liquid will be discharged from the inside of the drain pipe 9;

[0035] After the reaction liquid is discharged, valve 2 14 can be opened, and the driving component 15 can be driven to rotate the rotating disk 16, and then the rotating disk 16 will connect the shell 17 and the extrusion wheel 18 to rotate, and then when the extrusion wheel 18 rotates, it will squeeze the surface of the hose 13. While squeezing, the pressure inside the hose 13 will decrease. While the pressure inside the hose 13 decreases, the reaction liquid remaining in the drain pipe 9 will be absorbed to prevent the reaction liquid from flowing back into the cavitation chamber 7, and then the reaction liquid will be discharged from the inside of the hose 13, and then the reaction liquid will flow to the top of the guide plate 3, and then the guide plate 3 will guide the reaction liquid to the inside of the collection tank 25, and then the collection tank 25 can collect the reverse liquid, and finally complete the operation process.
