Description

Chlorine dioxide aqueous solution mixer

The present invention relates to a mixer, and more particularly to a mixer for mixing chlorine dioxide gas with water to form an aqueous solution of chlorine dioxide.

It is known that chlorine dioxide (ClO ₂ ) has the function of disinfection and sterilization, and the chlorine dioxide aqueous solution prepared by dissolving chlorine dioxide in water can be applied to health care industry, food processing industry, animal husbandry, industrial water, environment. Engineering and other fields for sterilization and deodorization. Referring to Figures 1 and 2, there is a known aqueous chlorine dioxide mixer comprising a body 11 having a hollow tubular shape and having an air inlet 111, and an intake pipe 12 fixed to the air inlet 111 by a screw. And a screw 13 and a diffuser 14 coupled to opposite sides of the body 11. The body 11 further has an arc-shaped outer peripheral surface 112 through which the air inlet hole 111 penetrates toward the inner circumferential surface. The intake pipe 12 is capable of transporting chlorine dioxide gas into the body 11. The nozzle 13 has a water outlet end 131 extending into the interior of the body 11, and a water inlet end 132 opposite to the water outlet end 131. The diffuser 14 has an inlet end 141 that is locked to the body 11 and an outlet end 142 that is opposite the inlet end 141.

When the chlorine dioxide aqueous solution mixer is used, the water liquid enters the inside of the nozzle 13 from the water inlet end 132 of the nozzle 13 and is conveyed toward the diffusing member 14, and the inside of the nozzle 13 and the inner pipe of the diffusing member 14 are pipes. The change in the aperture is designed such that the flow rate of the water passing through the outlet end 131 of the nozzle 13 and the inlet end 141 of the diffuser 14 is faster, thereby forming a pressure difference between the nozzle 13 and the internal conduit of the diffuser 14 The suction force formed by the pressure difference can attract the chlorine dioxide gas in the intake pipe 12 into the body 11 and mix in the water to form an aqueous solution of chlorine dioxide, and the diffusion member 14 The outlet end 142 is discharged.

Although the mixer can achieve the function of mixing to form an aqueous solution of chlorine dioxide, its structural design leads to a defect in manufacturing, mainly because the body 11 must be provided with the inlet hole 111 for the inlet pipe 12 to be screwed, and The air inlet hole 111 is formed by machining the body 11 through a workpiece (not shown). However, since the outer peripheral surface 112 of the body 11 has a circular arc surface as a whole, the circular arc surface cannot be formed. As the abutting surface during the processing of the workpiece, the workpiece is easily skewed when the drilling process is performed, so that the central axis of the air inlet hole 111 formed by the machining is skewed, and the air intake hole 111 is Insufficient machining accuracy will result in subsequent difficulty in locking the intake pipe 12, or the intake pipe 12 may not be stable after screwing, or the airtightness between the pipes may be poor, so the mixer structure is known to be improved.

Therefore, the object of the present invention is to provide a chlorine dioxide aqueous solution mixer which has high hole forming precision, is easy to assemble, and is assembled stably.

Thus, the novel chlorine dioxide aqueous solution mixer comprises a body, an intake pipe, a nozzle, and a diffuser. The body includes an inner circumferential surface defining a body duct, an outer circumferential surface opposite to the inner circumferential surface, and an air inlet hole extending through the inner circumferential surface and the outer circumferential surface, the outer circumferential surface having at least one planar surface In the flat portion, the air inlet hole is a screw hole and is located at the plane portion. The intake pipe is screwed to the intake port and used to transport chlorine dioxide gas into the body. The nozzle is coupled to one end of the body and has a first conduit that communicates with the body conduit for water supply injection. The diffusing member is coupled to the other end of the body and has a second conduit communicating with the body conduit for discharging the aqueous chlorine dioxide solution formed by mixing chlorine dioxide gas and water.

The effect of the present invention is that at least one of the planar portions is provided on the outer peripheral surface of the body, and the planar portion can serve as an abutment surface of the workpiece when the workpiece is processed to form the air intake hole. The processing precision of the air inlet hole is improved, so that the body and the air inlet tube are easily screwed and assembled, and the assembly is stable.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 3 and 4, a first embodiment of the novel chlorine dioxide aqueous solution mixer comprises: a hollow body 2, an intake pipe 3, a nozzle 4, and a diffuser 5.

The body 2 is a hollow and axially extending tubular member. The body 2 includes an inner peripheral surface 21 defining a body duct 20 extending in an axial direction thereof, an outer peripheral surface 22 opposite to the inner peripheral surface 21, and a through-the inner peripheral surface 21 and the outer peripheral surface 22 And communicating with the air inlet hole 23 of the body duct 20. The outer peripheral surface 22 has a plurality of planar portions 221 that are connected and planar. The air inlet hole 23 is a screw hole and is located on one of the flat portions 221 . Although the peripheral surface 22 of the present embodiment is such that the six planar portions 221 are connected to form a hexagonal surface, in practice, the outer circumferential surface 22 may have at least one planar portion 221, and the air inlet hole 23 is still It is located on the flat portion 221, and other non-planar regions of the outer peripheral surface 22 may be curved surfaces.

The intake pipe 3 is an uprightly extending pipe member and is screwed and fixed to the intake hole 23. The intake pipe 3 is for supplying chlorine dioxide gas into the body 2.

The nozzle 4 is a hollow tubular member and is screw-locked to one end of the body 2. The nozzle 4 includes a nozzle tube portion 41, and a narrowed tube portion 42 connected to one end of the nozzle tube portion 41 and extending into the body tube 20. The nozzle tube portion 41 and the narrowed tube portion 42 define a joint The body conduit 20 is passed through and used to supply the injected first conduit 40. Wherein, the nozzle tube portion 41 has a water inlet end 411 away from the narrow tube portion 42, and the water inlet end 411 has a plurality of first internal threads 412. The portion of the nozzle tube portion 41 that connects the narrowed tube portion 42 has a plurality of first external threads 413 for screwing with the body 2. The narrowed tube portion 42 has a water outlet end 421 located within the body conduit 20 opposite the water inlet end 411. The diameter of the pipe of the first pipe 40 at the nozzle pipe portion 41 is substantially the same, and the diameter of the pipe where the first pipe 40 extends from the nozzle pipe portion 41 toward the narrowed pipe portion 42 is gradually reduced.

The diffusing member 5 is a hollow tubular member coupled to the body 2 opposite to one end of the nozzle 4. The diffusing member 5 includes an assembled tubular portion 51 that is screw-coupled to the body 2, and an outlet tubular portion 52 that is coupled to one end of the assembled tubular portion 51. The assembly tube portion 51 and the outlet tube portion 52 together define a second conduit 50. The assembly tube portion 51 has an inlet end 511 located in the body conduit 20 and facing the water outlet end 421 of the nozzle 4, the inlet end 511 having a plurality of second external threads 512 threadedly coupled to the body 2. The outlet tube portion 52 has an outlet end 521 opposite the inlet end 511, the outlet end 521 having a plurality of second internal threads 522. The diameter of the conduit of the second conduit 50 at the outlet tube portion 52 is greater than the diameter of the conduit at the assembly tube portion 51.

In the present invention, the water liquid enters the inside of the nozzle 4 from the water inlet end 411 of the nozzle 4, and is conveyed toward the diffuser 5 via the water outlet end 421. Moreover, by reducing the design of the pipe at the water outlet end 421 of the first pipe 40 of the nozzle 4, the flow rate of the water flowing to the water outlet end 421 can be accelerated, and a high-speed jet water flow can be formed and enter the diffuser 5. Moreover, since the pipe of the water outlet end 421 is smaller than the pipe of other parts, the flow rate of the water liquid is faster, thereby forming a pressure difference between the nozzle 4 and the diffusion member 5, and the pressure difference is formed by the pressure difference. The suction force can attract the chlorine dioxide gas in the intake pipe 3 into the body 2, and is driven by the force of the water liquid sprayed from the nozzle 4 to the diffusing member 5 and mixed with the water and liquid to form two Oxidized chlorine solution. An aqueous solution of chlorine dioxide can pass through the second conduit 50 of the diffuser 5 and be discharged from the outlet end 521 to provide to the desired location or equipment.

It is to be noted that, since the outer peripheral surface 22 of the body 2 is provided with at least one of the flat portions 221, when the body 2 is machined and drilled through a workpiece (not shown) to form the air inlet hole 23, the The flat portion 221 can serve as an abutting surface for machining the workpiece to stabilize the direction of the workpiece so that the workpiece is kept in a constant direction during the drilling process without skewing, so that the central axis of the air inlet hole 23 formed by the processing is straight and not skewed. Therefore, the design of the plane portion 221 can improve the processing precision of the air inlet hole 23, and the air intake tube 3 is easy to be aligned and facilitates assembly and locking, and the air inlet tube 3 is screwed and stabilized, and the air inlet tube 3 is stabilized. The pipe between the body 2 and the body 2 can achieve good airtightness. In addition, the water inlet end 411 of the nozzle 4 and the outlet end 521 of the diffuser 5 of the embodiment need to be locked with other pipelines not shown, so the nozzle 4 is provided with the first internal thread 412. The diffuser 5 is provided with the second internal threads 522. Moreover, the advantage of providing the internal thread instead of the external thread in these parts is that the external thread is susceptible to collision, rubbing or other friction loss when the components are not assembled and stored or transported due to the external thread being exposed on the outer peripheral surface of the pipe. Therefore, the precision and integrity of the thread are affected, so that the water inlet end 411 of the nozzle 4 and the outlet end 521 of the diffuser 5 are difficult to be screwed with other pipelines. Therefore, the present embodiment does not use the external thread but designs the first inner portion. The thread 412 and the second external thread 512 have the functions of protecting the thread and avoiding the damage of the thread, so that the pipeline is easy to be locked and screwed stably.

In summary, the outer peripheral surface 22 of the body 2 is provided with at least one flat portion 221, which can be lifted as the abutment surface of the workpiece when the workpiece is formed into the air inlet hole 23 The machining accuracy of 23 makes it easy to assemble the body 2 and the intake pipe 3, and the assembly is stable.

Referring to FIG. 5, the second embodiment of the present invention is similar to the structure of the first embodiment. The difference is that the outer peripheral surface 22 of the body 2 of the embodiment includes two upper and lower portions. The plane portions 221 opposite to each other and the two arc portions 222 spaced apart from each other and connected to the plane portions 221 are disposed. In this embodiment, the air intake hole 23 is provided through one of the flat portions 221 to achieve the same effect as the first embodiment.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
