Description

Technical Field

[0001] The utility model relates to the technical field of water treatment equipment, in particular to a pure water treatment and filtering device based on a turbulent flow type. Background Art

[0002] In current pure water treatment processes, the front-end precision filter usually needs to add chemicals to meet the operating conditions. However, the existing treatment method generally requires the use of an additional flange-connected pipeline mixer to ensure more complete dosing and achieve better mixing effect.

[0003] This method has many disadvantages. On the one hand, it adds additional costs, including the purchase cost of the pipeline mixer and the installation cost of the flange connection. On the other hand, the compatibility between the pipeline mixers and precision filters on the market is often poor, which affects the stability of the back-end process and leads to poor overall pure water treatment results. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology and propose a pure water treatment filtration device based on turbulence to solve the problems of the existing technology that require additional pipeline mixers, high costs and poor matching that affect the stability of the back-end process.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] A pure water treatment and filtering device based on a turbulent flow type comprises a filter cylinder, a water inlet pipe and a water outlet pipe, wherein a turbulent flow rotating impeller, a bearing, a main shaft and an impeller bracket are arranged in the water inlet pipe;

[0007] The main shaft is rotatably connected to the impeller bracket through a bearing, the turbulent rotating impeller is fixedly connected to the extended end of the main shaft, and the impeller bracket is welded in the water inlet pipe.

[0008] As a further description of the above technical solution: the impeller bracket is a cross, and a plurality of reinforcing ribs are provided on the surface of the impeller bracket.

[0009] As a further description of the above technical solution: the turbulent rotating impeller includes a circular mounting plate and blades, the number of the blades is multiple, all of the blades are evenly distributed on the outside of the mounting plate, and the mounting plate is fixedly connected to the main shaft.

[0010] As a further description of the above technical solution: the blades are twisted blades and are installed obliquely on the mounting plate, and the inclination angle of the blades is 15-30 degrees.

[0011] As a further description of the above technical solution: the number of the blades is 3-6, and the mounting plate and the blade surfaces are both coated with a wear-resistant coating.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] 1. Reduce costs: This device does not require an additional pipeline mixer, saving the purchase cost of the pipeline mixer and the installation cost of the flange connection, thereby reducing the overall cost of the equipment.

[0014] 2. Improve matching and stability: Since the reagent mixing function is integrated into the filter device, the problem of poor matching between the pipeline mixer and the precision filter affecting the stability of the back-end process is avoided, and the stability of the entire pure water treatment process is improved.

[0015] 3. Efficient mixing: The spiral vortex formed by the turbulent rotating impeller when the water enters can effectively stir the mixed reagents, improve the efficiency of reagent mixing, and thus better meet the requirements of pure water treatment. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-2A pure water treatment and filtration device based on a turbulent flow method includes a filter cartridge 1, an inlet pipe 2, and an outlet pipe 7. A turbulent flow rotating impeller 3, a bearing 5, a main shaft 6, and an impeller bracket 4 are disposed within the inlet pipe 2. The main shaft 6 is rotatably connected to the impeller bracket 4 via the bearing 5. The turbulent flow rotating impeller 3 is fixedly connected to the extended end of the main shaft 6, and the impeller bracket 4 is welded within the inlet pipe 2. During the pure water treatment process, when water containing a chemical enters the inlet pipe 2, the water flow creates resistance on the turbulent flow rotating impeller 3. Due to the support of the bearing 5 and the main shaft 6, the turbulent flow rotating impeller 3 begins to rotate, forming a spiral vortex. This vortex stirs and mixes the chemical within the inlet pipe 2, fully mixing the chemical with the water.

[0023] The mixed water enters the filter cylinder 1, where it passes through the internal filtration unit to remove impurities. The treated pure water flows out of the outlet pipe 7, meeting the requirements of pure water treatment. During the entire operation process, since no additional pipeline mixer is required, the complexity of the equipment is reduced and the reliability and stability of the equipment are improved.

[0024] In addition, the impeller bracket 4 is a cross, and a plurality of reinforcing ribs 8 are provided on the surface of the impeller bracket 4 to enhance the structural strength of the impeller bracket 4 and ensure stable support for the turbulent rotating impeller 3, bearing 5 and main shaft 6 under the impact of water flow.

[0025] like Figure 2 、 3 As shown, the turbulent impeller 3 includes a circular mounting plate 31 and blades 32. The number of blades 32 is multiple, and all blades 32 are evenly distributed on the outside of the mounting plate 31. The mounting plate 31 is fixedly connected to the main shaft 6. Among them, the blades 32 are twisted blades (there is a certain twisting angle from the root to the tip. When the impeller rotates, the blades 32 will generate a tangential force on the water flow. This tangential force will cause the water flow to form a spiral flow path on the surface of the blades 32) and are installed on the mounting plate 31 at an angle. The inclination angle of the blades 32 is 15-30 degrees. For example, the blades are installed on the mounting plate 31 at an angle of 20 degrees. When the water flow hits the blades, due to this inclination angle, the water flow will be forced to deflect in the counterclockwise direction, which helps to form a spiral vortex.

[0026] Furthermore, the number of blades 32 is 3-6, and the surfaces of the mounting plate 31 and the blades 32 are coated with a wear-resistant coating to reduce the wear of the turbulent rotating impeller 3 caused by water flow erosion and extend the service life of the turbulent rotating impeller 3.

[0027] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
