Description

Title of Invention: Chlorine Dioxide Aqueous Mixer

Technical field

[0001] 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.

Background technique

[0002] Chlorine dioxide (C10 ₂ ) is known to have a disinfecting and sterilizing function, and the chlorine dioxide aqueous solution prepared by dissolving chlorine dioxide in water can be applied to the medical care industry, food processing industry, animal husbandry, industry. Used in water, environmental engineering and other fields for sterilization and deodorization. Referring to Figures 1 and 2, a known aqueous chlorine dioxide mixer comprises: 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 lock. And a nozzle 13 and a diffuser 14 coupled to opposite sides of the body 11. The main body 11 further has a circular arc-shaped outer peripheral surface 112, and the air inlet hole 111 penetrates from the outer circumferential surface 112 toward the inner circumferential surface thereof. 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.

[0003]

The chlorine dioxide aqueous solution mixer uses hydrazine, and 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 portion 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 142 of the diffuser 14 is slower than the flow rate through the inlet end 141, thereby forming a pressure difference between the nozzle 13 and the internal conduit of the diffuser 14, By the suction force formed by the pressure difference, the chlorine dioxide gas in the intake pipe 12 can be sucked into the body 11 and mixed in water to form an aqueous chlorine dioxide solution, and the diffusion member 14 is formed. The outlet end 14 2 is discharged.

[0004] 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. 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-shaped surface as a whole, the circular arc-shaped surface cannot be used as an abutting surface of the workpiece, so that the workpiece is subjected to drilling and the skew is easy to occur. Therefore, the central axis of the air inlet hole 111 formed by the machining is skewed, and the machining accuracy of the air inlet hole 111 is insufficient, which may cause the intake pipe 12 to be difficult to be locked later, or the intake pipe 12 may be screwed. Not stable enough, or the air tightness between the pipes will be poor, so the mixer structure is known to be improved.

BEST MODE FOR CARRYING OUT THE INVENTION

[0019] The paragraphs describing the best mode of the invention are entered here.

Embodiments of the invention

[0020] 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.

[0021] 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.

[0022] 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, the outer circumferential surface 22 may have at least one planar portion 221, and the air inlet hole 23 may still be It is located on the flat portion 221, and the region of the other non-planar portion 221 of the outer peripheral surface 22 may be a curved surface.

[0023] The intake pipe 3 is an upright 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.

[0024] 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 narrowing 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 narrowing tube portion 42 are defined together A first conduit 40 that communicates with the body conduit 20 and is used for water injection. 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-down tube portion 42 has a water outlet end 421 located in the body duct 20 opposite to the water inlet end 411. The diameter of the pipe at the nozzle pipe portion 41 of the first pipe 40 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.

[0025] The diffusing member 5 is a hollow tubular member coupled to the body 2 opposite to one end of the nozzle 4. The diffuser 5 includes an assembled tubular portion 51 that is threadedly 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 52 2 . 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.

[0026] The present invention uses hydrazine, and 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 42 1 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. After the water enters the diffuser 5, the inlet end 511 flows to the outlet end 521 吋, because the second pipe 50 is enlarged in the pipe of the outlet pipe portion 52 with respect to the inlet pipe portion 51, the water flow rate is lowered, thereby forming a pressure difference between the nozzle 4 and the diffuser 5, and By the suction force formed by the pressure difference, the chlorine dioxide gas in the intake pipe 3 can be sucked into the body 2, and is driven by the force of the water liquid sprayed from the nozzle 4 to the diffuser 5 and The aqueous liquid is mixed to form an aqueous chlorine dioxide 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.

[0027] It is worth mentioning that since at least one of the planar portions 221 is provided on the outer peripheral surface 22 of the body 2, the body 2 is machined and drilled through a workpiece (not shown) to form the air intake hole. 23吋, the plane portion 22 1 can serve as an abutting surface of the workpiece machining boring to stabilize the workpiece direction, so that the workpiece is kept in a constant direction without being skewed in the drilling process, so that the center of the air inlet hole 23 formed by machining The axis is straight and not inclined, so the design of the plane portion 221 can improve the processing precision of the air inlet hole 23, and the air intake pipe 3 is easy to be aligned and facilitates assembly and locking, and the air inlet pipe 3 is screwed and stabilized. The pipe between the gas pipe 3 and the body 2 can achieve good airtightness. Furthermore, the water inlet end 411 of the nozzle 4 and the outlet end 52 1 of the diffuser 5 of the embodiment need to be locked with other pipelines not shown, so that 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 since the external thread is exposed on the outer peripheral surface of the pipe member, when the components are not assembled and are stored or transported, the external thread is easily subjected to collision, rubbing or other friction loss. 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 pipes, so 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 function of protecting the thread and avoiding the damage of the thread, so that the pipeline is easy to be locked and the thread is firmly fixed.

[0028] In summary, the outer peripheral surface 22 of the body 2 is provided with at least one flat portion 221, and the air inlet hole 23 is formed in the workpiece as the abutment surface of the workpiece, which can be raised. The machining accuracy of the intake hole 23 facilitates assembly between the body 2 and the intake pipe 3, and the assembly is stable.

[0029] Referring to FIG. 5, a second embodiment of the present novel chlorine dioxide aqueous solution mixer is substantially the same as the first embodiment, except that the outer peripheral surface 22 of the body 2 of the present embodiment includes Two flat portions 221 spaced apart from each other and two arc portions 222 spaced apart from each other and connected to the flat portions 221 are disposed. In this embodiment, the same effect as the first embodiment can be achieved by the through hole 23 being provided through one of the flat portions 221. However, the above is only an embodiment of the present invention, and when it is not possible to limit the scope of the present invention, any simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification are still This new patent covers the scope.
