Description

Technical Field

[0001] This utility model belongs to the field of water treatment equipment, specifically relating to a pipeline mixer. Technical Background

[0002] Metallurgical and chemical production processes generate large amounts of wastewater that require treatment. A common treatment method is to mix chemicals with the wastewater to induce a coagulation reaction, thereby purifying the wastewater. However, traditional pipeline mixers often experience uneven mixing when wastewater and chemicals enter the main pipeline. Furthermore, some pipeline mixers use electric motors to improve mixing efficiency, but this consumes a lot of energy. Therefore, there is an urgent need to design a new type of pipeline mixer. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a pipeline mixer, mainly to solve the problem of uneven mixing of wastewater and reagents.

[0004] This application provides a pipeline mixer, which adopts the following technical solution:

[0005] A pipeline mixer includes an inlet, an outlet, a dosing port, and a pipe body. One side of the pipe body is the inlet and the other side is the outlet. The dosing port is provided on the pipe body near the inlet. Inside the pipe body, from the inlet to the outlet, a spiral blade, a grid plate, a baffle, a circular hollow sphere, and a turbulence block are arranged in sequence.

[0006] Optionally, a number of inlet blades are provided at the inlet, preferably 4 blades.

[0007] The above technical solution can achieve the effect of wastewater premixing, reduce the load on subsequent mixing units, increase the turbulence intensity of wastewater, and improve mixing efficiency.

[0008] Optionally, the dosing port adopts an atomizing nozzle structure, with many small round holes distributed on the atomizing nozzle.

[0009] By adopting the above technical solution, the agent is dispersed into small droplets, which increases the contact area between the agent and the wastewater and facilitates mixing.

[0010] Optionally, one end of the spiral blade is connected to the inlet blade, and the other end is connected to the bar screen.

[0011] By adopting the above technical solution, the stability of the spiral blade structure can be maintained, while the grid plate can enhance the mass transfer function of the solution.

[0012] Optionally, the baffles are all fixedly connected to the inner wall of the pipe, and the included angle between them and the pipe is 60°.

[0013] By adopting the above technical solution, the flow path of wastewater can be changed and the mixing efficiency can be improved.

[0014] Optionally, the center of the circular hollow sphere is connected to the upper and lower ends of the inner wall of the tube via a support shaft, and the circular hollow sphere is rotatably mounted on the support shaft.

[0015] Optionally, the diameter of the tube at the location of the circular hollow sphere is smaller than the diameter of the tube at other locations.

[0016] By adopting the above technical solution, the flow velocity of wastewater is increased by changing the diameter, which drives the circular hollow sphere to rotate, thereby achieving the effect of stirring and mixing.

[0017] Optionally, the baffle blocks are fixed to the inner wall of the pipe, and the two baffle blocks are arranged axially opposite each other.

[0018] By adopting the above technical solution, the turbulence block can play a collision role, increase turbulence intensity, and improve mixing efficiency.

[0019] In summary, the beneficial results of this utility model are: the pipeline mixer provided by this utility model adopts multiple structural designs, and the liquid and the agent undergo multiple complex water processes such as dispersion, collision and mixing inside the pipeline mixer, which effectively improves the mixing efficiency of the liquid and the agent.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] This application discloses a pipeline mixer, including a pipe body 1, an inlet 2, an outlet 3, and a chemical dosing port 4. The inlet 2 and outlet 3 are located on the left and right sides of the pipe body 1, respectively. The chemical dosing port 4 is provided on the pipeline. The inlet 2 is provided with an inlet blade 21. The chemical dosing port 4 adopts an atomizing nozzle 41 structure. The pipe body 1 is provided with a spiral blade 5, a grid plate 6, a baffle 7, a circular hollow ball 8, and a turbulence block 9.

[0027] Furthermore, the number of inlet blades 21 is 4.

[0028] Furthermore, the atomizing nozzle 41 is distributed with many small round holes 42.

[0029] Furthermore, one end of the spiral blade 5 is connected to the inlet blade 21, and the other end is connected to the grating plate 6.

[0030] Furthermore, all baffles 7 are fixedly connected to the inner wall of the tube body 1, and the included angle between them and the tube body 1 is 60°.

[0031] Furthermore, the center of the circular hollow sphere 8 is connected to the upper and lower ends of the inner wall of the tube body 1 through a support shaft 81. The circular hollow sphere 8 is rotatably mounted on the support shaft 81, and the diameter of this section of the tube body 1 is smaller, forming a variable diameter area.

[0032] Furthermore, the baffle block 9 is fixed to the inner wall of the pipe body 1, and the two baffle blocks 9 are arranged axially opposite each other.

[0033] The implementation principle of a pipeline mixer in this application embodiment is as follows:

[0034] Wastewater enters inlet 2, driving the inlet blades 21 to rotate and achieve initial mixing. Simultaneously, the atomizing nozzle 41 at the dosing port 4 continuously sprays chemicals to mix with the wastewater. Under the action of the spiral blades 5, the wastewater and chemicals continuously rotate and mix. Then, the mixture collides and is diverted through the grid holes 61 on the grid plate 6. Subsequently, under the obstruction of the baffle 7, the mixture continues to collide, causing turbulent flow and achieving thorough contact mixing. The solution then passes through the variable diameter zone, where its velocity increases, and is further stirred and dispersed by the circular hollow sphere 8. Subsequently, the solution's flow direction is further changed by the turbulence block 9, increasing the turbulence intensity, before being discharged through outlet 3. The entire process involves multiple collisions, dispersion, mixing, and continuous changes in flow direction, increasing the contact area and probability between the wastewater and chemicals, effectively improving their mixing effect.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
