Abstract
Description
Technical Field
[0001] The utility model relates to the field of mixing equipment, in particular to a multi-purpose pipeline mixer. Background Art
[0002] Pipeline mixers, also known as tubular static mixers, are very effective in adding various coagulants, coagulant aids, ozone, liquid chlorine, acid-base neutralization, and gas-water mixing in water supply and drainage and environmental protection projects. They are ideal equipment for instant mixing of various chemicals in water treatment. Without the need for external power, water flowing through the pipeline mixer will produce three effects: diversion, cross-mixing, and reverse vortex, allowing the added chemicals to be quickly and evenly diffused throughout the water body.
[0003] Traditional pipeline mixers mainly have different forms of folding plates, water baffles, special-shaped plates, etc. in the pipe to make the water flow in different directions and fully mix with the added reagents, but there are the following disadvantages:
[0004] 1. Affected by the viscosity of the liquid: The gap between the separation plates of the tubular static mixer is small, which can easily cause blockage when processing liquids with high viscosity;
[0005] 2. Difficult to adapt to large flow mixing: Due to the complex internal structure and large resistance of the static mixer, the flow itself is greatly restricted, making it difficult to apply to processes with large flow;
[0006] 3. Not suitable for gas-liquid mixing: Tubular static mixers are mainly used for liquid mixing. They cannot achieve the ideal mixing effect for gas-liquid mixing and require other mixing equipment to cooperate. Utility Model Content
[0007] The purpose of the utility model is to provide a multi-purpose pipeline mixer to solve the problems raised in the background technology.
[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-purpose pipeline mixer, comprising a mixing cylinder, an inlet flange arranged at one end of the mixing cylinder, and an outlet flange arranged at the other end of the mixing cylinder, wherein a first mounting bracket is arranged in the mixing cylinder, a first-level mixer is arranged on the first mounting bracket, a dosing tube is connected to one side of the first-level mixer, one end of the dosing tube extends out of the mixing cylinder, a main inlet and a plurality of sub-inlets arranged around the main inlet are arranged on the first-level mixer, and the main inlet and the outlets of the sub-inlet converge to form a mixing nozzle. The dosing tube can add medicine and pass steam. Crystallization may occur after the dosing nozzle is used for a long time. At this time, steam can be passed to increase the local temperature, improve the solubility of the medicine, and solve the crystallization problem.
[0009] As a further improvement of the above technical solution:
[0010] The mixing cylinder body includes a first mixing section and a second mixing section, and the first mixing section and the second mixing section are connected by a flange.
[0011] Reducing sections are provided at the distal ends of both the first mixing section and the second mixing section.
[0012] A second mounting bracket is provided on one side of the first mounting bracket. A conical reflector is provided on the second mounting bracket. The conical reflector is arranged at the outlet end of the mixing nozzle and is used for reflecting the liquid ejected from the mixing nozzle.
[0013] A perforated plate is provided between the first mixing section and the second mixing section, and a plurality of water passing holes are provided on the perforated plate.
[0014] A bottom discharge valve is provided on the mixing cylinder body.
[0015] The ratio of the bottom diameter of the conical reflector to the diameter of the mixing cylinder body is 1:(2 - 5).
[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0017] For the multi-purpose pipeline mixer of the present utility model, compared with the traditional pipeline mixer, the internal special-shaped folding plates are cancelled, greatly reducing the internal resistance and increasing the treatment flow rate. Three times of full mixing from partial to overall are designed to make the mixing more sufficient: First, using the forward power when adding the medicament to suck multiple water flows into the nozzle for partial mixing; Second, a reflector plate is designed at the outlet of the nozzle to reflect the water from the first-step partial mixing, forming a convection with the water inlet of the pipeline mixer for full mixing; Third, a perforated plate is provided, and the water from the second mixing passes through the perforated plate to form multiple water flows for re-mixing.
[0018] In addition, the present utility model adopts a two-section mixing cylinder body, and the perforated plate is clamped between the two end cylinder bodies and can be detachably withdrawn. After long-term use, pollutants, medicaments, etc. are likely to adhere to the perforated plate. In the present utility model, the perforated plate is clamped by two flanges, and the flanges can be regularly disassembled to withdraw the perforated plate for flushing, which is convenient to use.

[0034] Embodiment 1
[0035] As Figures 1 to 4 shown, the multi-purpose pipeline mixer of this embodiment includes a mixing cylinder body 1, an inlet flange 11 provided at one end of the mixing cylinder body 1, and an outlet flange 12 provided at the other end of the mixing cylinder body 1. A first mounting bracket 7 is provided inside the mixing cylinder body 1, and a primary mixing body 2 is provided on the first mounting bracket 7. A chemical addition pipe 3 is connected to one side of the primary mixing body 2, and one end of the chemical addition pipe 3 extends out of the mixing cylinder body 1. A main inlet 21 and several sub-inlets 22 arranged around the main inlet 21 are provided on the primary mixing body 2, and the outlets of the main inlet 21 and the sub-inlets 22 converge to form a mixing nozzle 23. The primary mixing body 2 is an integrally formed cylindrical monomer and is fixed inside the mixing cylinder body 1 by the first mounting bracket 7. There are five holes on the water inlet side of the primary mixing body 2. One hole is the nozzle chemical inlet, i.e., the main inlet 21, which is connected to the chemical addition pipe 3 and runs through the entire nozzle to the mixing nozzle 23. The other 4 holes are sub-inlets 22 and are water inlets. The sub-inlets 22 are connected to the mixing nozzle 23. Since the chemical addition pump delivers the chemical with a certain pressure, when the chemical enters the main inlet 21 and flows towards the mixing nozzle 23, a suction force is formed, sucking the liquid in the mixing cylinder body 1 into the 4 sub-inlets 22, and then spraying out from the mixing nozzle 23 after mixing with the chemical. In this process, the water flow and the chemical are locally mixed for the first time. Steam or other gases can also be introduced into the primary mixing body 2.
[0036] Embodiment 2
[0037] As Figure 5 and Figure 6As shown, a second mounting bracket 8 is provided on one side of the first mounting bracket 7, and a conical reflector 4 is provided on the second mounting bracket 8. The conical reflector 4 is provided at the outlet end of the mixing nozzle 23, and is used to reflect the liquid sprayed from the mixing nozzle 23. The conical reflector 4 is a conical monomer, and one side of the cone tip faces the center of the mixing nozzle 23. The bottom of the cone is fixed inside the mixing cylinder 1 by the second mounting bracket 8. When the locally mixed water and the agent are sprayed from the mixing nozzle 23, they are sprayed on the conical reflector 4, and then reflected to change the flow direction, forming convection with the water inlet of the pipeline mixer, so as to be fully mixed.
[0038] Example 3
[0039] like Figure 4 and Figure 5 As shown, the mixing cylinder 1 includes a first mixing section 14 and a second mixing section 15, and the first mixing section 14 and the second mixing section 15 are connected by a flange.
[0040] The first mixing section 14 and the second mixing section 15 are both provided with a reduced diameter section 13 at their distal ends.
[0041] A perforated plate 5 is provided between the first mixing section 14 and the second mixing section 15, and a plurality of water holes 50 are provided on the perforated plate 5. The diameter of the perforated plate 5 is the same as the diameter of the outer flange of the first mixing section 14 and the second mixing section 15. A circle of holes is opened on the outer periphery of the perforated plate 5 to connect with the bolt holes of the flange, and the flange and the perforated plate 5 are fixed with bolts. Nine perforated plate water holes 50 are opened on the perforated plate 5, and the mixed medicine and water form nine small water flows after passing through the perforated plate 5, and then stirred and mixed.
[0042] A bottom row valve 6 is provided on the mixing cylinder 1 .
[0043] The ratio of the bottom diameter of the conical reflector 4 to the diameter of the mixing cylinder 1 is 1:(2-5).
[0044] For ease of understanding, the following is a maximum water treatment capacity of 40m 3 / h pipeline mixer, the process requires adding 30% NaOH solution for mixing.
[0045] The mixing cylinder 1 is made of stainless steel 304, with a thickness of 5 mm and a diameter of 300 mm. It is divided into two sections and connected with DN300 stainless steel flanges. The diameters of both ends are reduced to DN100 mm and DN100 stainless steel flanges are used as inlet flange 11 and outlet flange 12.
[0046] The dosing pipe 3 is a DN20 stainless steel 304 pipe.
[0047] The primary mixer 2 is made of stainless steel 304, with a diameter of 80 mm and a height of 50 mm. The main inlet 21 has a diameter of 20 mm, the branch inlet 22 has a diameter of 10 mm, and the mixing nozzle 23 has a diameter of 40 mm.
[0048] The bottom diameter of the conical reflector 4 is 100 mm, and the height is 50 mm. It is rolled from a 5-mm-thick stainless steel 304 plate.
[0049] The perforated plate 5 is a 4-mm-thick stainless steel 304 plate with 9 holes of DN50.
[0050] The first mounting bracket 7 and the second mounting bracket 8 are formed by welding 25*25*3-mm stainless steel angle irons and are installed in the mixing cylinder 1. The connection method is welding or bolt connection.
[0051] As Figure 9 shown, it is a schematic diagram of the liquid flow direction of the multi-functional pipeline mixer of the present utility model. When in use, the inlet flange 11 is connected to the liquid inlet pipe, and the outlet flange 12 is connected to the liquid outlet pipe. The liquid runs from the inlet flange 11 to the outlet flange 12. First, it passes through the reduced-diameter section 13 of the first mixing section 14 where the pipe diameter becomes larger and the liquid flow rate decreases. The liquid medicine is injected into the mixer through the medicine adding pipe 3. When the liquid medicine is ejected, it inhales the internal liquid for preliminary mixing and sprays out from the mixing nozzle 23, contacts the conical reflector 4. The conical reflector 4 reflects the locally mixed liquid to form a convection with the water inlet of the pipeline mixer, so that they are fully mixed. Then the liquid enters the perforated plate 5 and sprays out from multiple water passing holes 50 to form multiple water flows, which can realize re-mixing. After mixing, the liquid passes through the next reduced-diameter section 13 where the diameter becomes smaller, and the collision probability increases here, which is beneficial to mixing. The mixed liquid is discharged from the liquid outlet pipe. After running for a period of time, crystals will form on the perforated plate 5, and the water passing holes 50 may be blocked. At this time, open the bottom drain valve 6 to empty the liquid in the pipeline mixer, remove the bolts, open the flange and remove the perforated plate 5 for maintenance.
[0052] The above are only the embodiments of the present utility model. Common knowledge such as the specific structures and characteristics known in the solutions is not described in detail here. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.
