Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a solid-liquid mixing device and a reaction device. Background Technology

[0002] In chemical production processes, mixing is a crucial step that directly impacts product quality and production efficiency. A chemical mixing device is a type of equipment that uses mechanical stirring or high-speed rotation to subject different materials to high-speed rotation, shearing, and impact within a container, achieving uniform mixing. During this process, the rotating impellers or spiral blades inside the chemical mixing device generate centrifugal force, causing the materials to move outwards; the impellers or blades shear the materials during rotation, breaking down the interfaces between materials and promoting mixing; and the materials collide with each other during high-speed rotation, further breaking down and mixing them.

[0003] During the mixing of solid and liquid chemical materials, overflowing mist may appear in the viewing window of the chemical mixing device. This mist may be acidic or alkaline, which can contaminate the workshop and have adverse effects on the health of operators or equipment. Utility Model Content

[0004] This invention provides a solid-liquid mixing device and a reaction device to solve the technical problem of overflowing mist polluting the workshop during the mixing process of the above-mentioned chemical materials, which has an adverse effect on the health of operators or equipment.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: This utility model provides a solid-liquid mixing device, comprising: The vessel body is equipped with an openable viewing window; A splash guard is installed above the viewing window; and The negative pressure fan has an inlet end and an outlet end. The inlet end is connected to the splash guard via an air intake pipe, and the outlet end is connected to a sedimentation tank via a drain pipe. Along the air intake direction, the air intake pipe includes a first connecting section, a rapid contraction section, and a second connecting section in sequence.

[0006] In this invention, the negative pressure fan can draw the overflowing mist through the splash guard to the air intake pipe. When the mist flows through the constriction section, the cross-sectional area of ​​the pipe suddenly shrinks, the flow rate of the mist increases, the pressure drops, and the tiny droplets in the mist collide and merge with each other to form larger droplets, which become liquid flow. Then, the liquid flow enters the sedimentation tank through the drain pipe, thus avoiding the technical problem of overflowing mist polluting the workshop and causing adverse effects on the health of operators or equipment.

[0007] In one embodiment of this utility model, the air intake pipe is a rigid pipe.

[0008] In one embodiment of this utility model, the inner walls of both the air inlet pipe and the liquid outlet pipe are coated with an anti-corrosion layer.

[0009] In this invention, by coating the inner walls of both the air inlet pipe and the liquid outlet pipe with an anti-corrosion layer, it is possible to prevent acidic or alkaline spilled materials from corroding the pipes and extend their service life.

[0010] In one embodiment of this utility model, the viewing window is located at the top of the vessel body.

[0011] In this invention, by placing the viewing window at the top of the vessel, the risk of operators being directly exposed to the splash path can be reduced.

[0012] In one embodiment of this utility model, the viewing window is provided with a handle.

[0013] In this invention, a handle is added to the viewing window to facilitate opening or closing the window, thus improving convenience.

[0014] In one embodiment of this utility model, the splash guard is a conical splash guard.

[0015] In this invention, by setting the splash shield as a conical splash shield, the splashed mist can be guided to slide down the inclined surface through the tilt angle of the cone surface, avoiding vertical rebound and diffusion, and reducing the risk of secondary splashing.

[0016] In one embodiment of the present invention, the inner wall of the splash guard is coated with an anti-corrosion layer.

[0018] In one embodiment of this utility model, the vessel body is equipped with a stirrer.

[0019] In one embodiment of the present invention, the drain pipe is provided with a conical opening at one end near the sedimentation tank.

[0020] In this invention, a conical opening is added to one end of the drain pipe near the sedimentation tank. The conical opening includes an inlet end and an outlet end, with the outlet end close to the sedimentation tank. A buffer container is connected to the bottom edge of the conical opening, and the buffer container is connected to the sedimentation tank. This allows the liquid flow formed by the abrupt contraction section to flow out quickly through the conical opening. The conical opening, negative pressure fan, and buffer container create strong turbulence and rotation in the liquid flow, converting kinetic energy into heat energy for dissipation and reducing the impact damage of the liquid flow on the inner wall of downstream equipment. The buffer container can absorb the residual kinetic energy of the liquid flow, further reducing the impact damage of the liquid flow on the inner wall of downstream equipment.

[0028] One embodiment of this utility model provides a solid-liquid mixing device, comprising: The vessel body 1 has an openable viewing window 11 on the top, and a handle 111 on the viewing window 11. The vessel body 1 is equipped with a stirrer.

The inner walls of both the air intake pipe and the liquid discharge pipe 5 are coated with an anti-corrosion layer. The end of the drain pipe 5 near the sedimentation tank 6 is provided with a conical opening 51. The conical opening 51 includes an inlet end and an outlet end. The outlet end is close to the sedimentation tank 6. The bottom edge of the conical opening 51 is connected to a buffer container 7, which is connected to the sedimentation tank 6.

[0029] Another embodiment of the present invention provides a reaction apparatus, which includes the solid-liquid mixing device described above.

[0030] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0031] Please see Figure 1 , Figure 1 This is a schematic diagram of a solid-liquid mixing device according to an embodiment of the present invention. The solid-liquid mixing device includes a vessel body 1, a splash guard 2, a negative pressure fan 3, and a sedimentation tank 6.

[0032] Please continue reading. Figure 1 The vessel body 1 is used as a mixing place for solid and liquid chemical materials (such as hydrochloric acid solution, sulfuric acid solution, sodium hydroxide solution, etc.). A stirrer is installed inside the vessel body 1. Specifically, the stirrer is a conventional mixer, including a drive motor 12 and stirring blades (not shown). The stirring blades are located inside the vessel body 1, and the drive shaft of the drive motor 12 passes through the top of the vessel body 1, extends into the vessel body 1, and is fixedly connected to the stirring blades. An openable viewing window 11 is provided on the top of the vessel body 1, and a handle 111 is provided on the viewing window 11.

[0033] Specifically, this embodiment reduces the risk of operators being directly exposed to splash paths by placing the viewing window 11 on the top of the vessel body 1. Adding a handle 111 to the viewing window 11 facilitates opening and closing the window, improving convenience.

[0034] Please continue reading. Figure 1 The splash guard 2 is used to block the splash diffusion path of the mist formed by material splashing during the mixing process. The splash guard 2 is installed above the viewing window 11. The splash guard 2 is a conical splash guard, and the inner wall of the splash guard 2 is coated with an anti-corrosion layer (not shown). The anti-corrosion layer is made of a material that can resist acid and alkali corrosion, such as polytetrafluoroethylene, polyetheretherketone, etc.

[0035] Specifically, in this embodiment, by setting the splash shield 2 as a conical splash shield, the tilt angle of the cone surface can guide the splashed mist to slide down the inclined surface, avoiding vertical rebound and diffusion, and reducing the risk of secondary splashing. By coating the inner wall of the splash shield 2 with an anti-corrosion layer, it is possible to prevent acidic or alkaline spilled materials from corroding the splash shield 2, thus extending the service life of the splash shield 2.

[0036] Please continue reading. Figure 1 The negative pressure fan 3 provides power for the overflowing aerosol. The negative pressure fan 3 has an inlet and an outlet. The inlet is connected to the splash guard 2 via an air intake pipe, and the outlet is connected to the sedimentation tank 6 via a drain pipe 5. The air intake pipe is a rigid pipe. Along the air intake direction, the air intake pipe sequentially includes a first connecting section 41, a rapid contraction section 42, and a second connecting section 43. The inner walls of both the air intake pipe and the drain pipe 5 are coated with an anti-corrosion layer (not shown). The anti-corrosion layer is made of a material resistant to acid and alkali corrosion, such as polytetrafluoroethylene (PTFE) or polyetheretherketone (PEEK). The diameter of the rapid contraction section 42 is significantly smaller than that of the first connecting section 41. This causes the aerosol to flow through the rapid contraction section 42, resulting in a sudden reduction in the cross-sectional area of ​​the pipe, increasing the aerosol velocity, decreasing the pressure, and causing the tiny droplets in the aerosol to collide and merge, forming larger droplets, which then flow into the sedimentation tank 6 through the drain pipe 5.

[0037] Specifically, in this embodiment, by coating the inner walls of the air inlet pipe and the liquid outlet pipe 5 with an anti-corrosion layer, it is possible to prevent acidic or alkaline spilled materials from corroding the pipes and extend the service life of the pipes.

[0038] Please continue reading. Figure 1 The drain pipe 5 has a conical opening 51 at one end near the sedimentation tank 6. The conical opening 51 includes an inlet end and an outlet end, with the outlet end close to the sedimentation tank 6. The bottom edge of the conical opening 51 is connected to a buffer container 7 with a top opening; that is, the bottom edge of the conical opening 51 is connected to the buffer container 7, and the specifications of the bottom edge of the conical opening 51 are the same as the specifications of the top edge of the buffer container 7. In other words, the conical opening 51 and the buffer container 7 are connected as a single unit. The buffer container 7 is connected to the sedimentation tank 6. Figure 1 Both the medium negative pressure fan 3 and the buffer container 7 are mounted on a support plate 8. The support plate 8 has a through hole to facilitate the passage of pipes. The buffer container 7 is connected to the sedimentation tank 6 through a pipe passing through the through hole.

[0039] In this embodiment, a conical opening 51 is added to one end of the drain pipe 5 near the sedimentation tank 6. The conical opening 51 includes an inlet end and an outlet end, with the outlet end close to the sedimentation tank 6. A buffer container 7 is connected to the bottom edge of the conical opening 51 and is connected to the sedimentation tank 6. The conical opening 51 allows the liquid flow formed after passing through the abrupt contraction section 42 to flow out quickly. The conical opening 51, the negative pressure fan 3, and the buffer container 7 generate strong turbulence and rotation in the liquid flow, converting kinetic energy into heat energy for dissipation and reducing the impact damage of the liquid flow on the inner wall of downstream equipment. The buffer container 7 can absorb the residual kinetic energy of the liquid flow, further reducing the impact damage of the liquid flow on the inner wall of downstream equipment.

[0040] The principle of this embodiment is as follows: the negative pressure fan 3 can draw the overflowing mist through the splash shield 2 to the air intake pipe. When the mist flows through the sudden contraction section 42, the cross-sectional area of ​​the pipe suddenly shrinks, the flow rate of the mist increases, the pressure drops, and the tiny droplets in the mist collide and merge with each other to form larger droplets, which become liquid flow. Then, it enters the sedimentation tank 6 through the drain pipe 5, thus avoiding the technical problem of overflowing mist polluting the workshop and causing adverse effects on the health of operators or equipment.

[0041] This invention also provides a reaction apparatus, which includes the solid-liquid mixing device shown above.

[0042] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
