Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mixer technology, and in particular to a corrosion-resistant mixer. Background Technology
[0002] Pipeline mixers, also known as tubular static mixers, are highly effective in water supply, drainage, and environmental protection engineering for adding various coagulants, flocculants, ozone, liquid chlorine, and for acid-base neutralization and gas-water mixing. They are ideal equipment for achieving instantaneous mixing of various chemicals in water treatment, featuring rapid and efficient mixing, simple structure, energy saving, and compact size. Without the need for external power, water flowing through the pipeline mixer will produce three effects: diversion, cross mixing, and reverse swirling flow, allowing the added chemicals to quickly and evenly diffuse throughout the water body, achieving the purpose of instantaneous mixing.
[0003] Most existing mixers are made of 304 stainless steel, but 304 stainless steel has poorer corrosion resistance than 316L stainless steel. In addition, the curved blades in existing mixers that mix multiple liquids are mostly fixedly welded to the inside of the mixing tube. After long-term use, the surface of the existing curved blades will accumulate impurities or scale from various liquids, or rust will occur. Since the existing curved blades are welded to the inside of the mixing tube, they cannot be disassembled and replaced. Therefore, the entire mixer needs to be replaced, which greatly increases the cost of maintenance and replacement. Therefore, there is an urgent need for a corrosion-resistant mixer to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide a corrosion-resistant mixer to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant mixer, comprising a mixing pipe for mixer installation and multiple curved blades for liquid mixing, wherein a liquid inlet pipe is connected to the side wall of the mixing pipe, a flange is fixedly connected to the end of the mixing pipe, a through hole is provided through the side wall of the flange, a screw is slidably passed through the inside of the through hole, and a circular groove is provided on the side wall of the flange.
[0006] An installation plate is slidably installed inside the circular groove. A connector is fixedly connected to the side of the installation plate near the mixing tube. The side wall of the curved blade is fixedly connected to the inner wall of the connector, and the connector is slidably inserted into the interior of the mixing tube.
[0007] The side wall of the mounting plate has multiple circular holes corresponding to the flange, and the screw slides through the circular holes.
[0008] Preferably, a plurality of springs are fixedly connected to the side of the mounting plate near the inner wall of the circular groove, and the ends of the springs are slidably connected to the inner wall of the circular groove.
[0009] Preferably, the inner wall of the circular groove on the side wall of the flange is provided with a plurality of spring grooves, and the ends of the plurality of springs away from the mounting plate are installed inside the spring grooves.
[0010] Preferably, the sidewalls of the curved blades are all fixedly bonded with sealing strips, and the outer wall of the sealing strips slides against the inner wall of the mixing tube.
[0011] Preferably, a sealing ring is fixedly bonded to the outer wall of the insertion tube, and the outer wall of the sealing ring is sealed and fitted to the inner wall of the mixing tube.
[0012] Preferably, the curved blades are multiple welded together, and the arc angles of two adjacent curved blades are opposite.
[0013] Preferably, the mixing tube and the multiple curved blades are all made of L stainless steel.
[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0015] This corrosion-resistant mixer benefits from the fact that the mixing tube and curved blades are made of L stainless steel, which greatly improves its internal corrosion resistance.
[0016] This corrosion-resistant mixer benefits from the design of the mounting plate, the insertion pipe, and the curved blades. The curved blades are slidably inserted into the inside of the mixing pipe, and the mounting plate is snapped into the inside of the circular groove opened on the side wall of the flange, which makes it easy to disassemble the curved blades inside the mixing pipe.
[0017] Compared with existing technologies, this corrosion-resistant mixer can effectively disassemble the curved blades inside the mixing tube used for mixing multiple liquids, thereby facilitating their replacement or cleaning. Attached Figure Description

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.
[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.
[0027] like Figures 1 to 3 The main structure of a corrosion-resistant mixer shown is a mixing pipe 1 for mixer installation and multiple curved blades 7 for liquid mixing. A liquid inlet pipe 2 is installed on the side wall of the mixing pipe 1. A flange 3 is fixedly connected to the end of the mixing pipe 1. A through hole is opened through the side wall of the flange 3. A screw 4 slides through the inside of the through hole. A circular groove 5 is opened on the side wall of the flange 3.
[0028] An installation plate 6 is slidably installed inside the circular groove 5. A connector 8 is fixedly connected to the side of the installation plate 6 near the mixing pipe 1. The side wall of the curved blade 7 is fixedly connected to the inner wall of the connector 8, and the connector 8 is slidably inserted into the interior of the mixing pipe 1. Thanks to the design of the connector 8, the two mixing pipes 1 are further sealed by the connector 8 being inserted into the interior of the mixing pipe 1, which can also further improve the stability of the curved blade 7. At the same time, thanks to the design of the installation plate 6, the connector 8, and the curved blade 7, and the fact that the curved blade 7 is slidably inserted into the interior of the mixing pipe 1, and the installation plate 6 is snapped into the interior of the circular groove 5 opened on the side wall of the flange 3, it is easy to disassemble the curved blade 7 inside the mixing pipe 1.
[0029] The side wall of the mounting plate 6 has multiple circular holes corresponding to the flange 3, and the screw 4 slides through the circular holes. This allows the mounting plate 6 to be positioned by the screw 4, while also further improving the sealing effect between the two flanges 3.
[0030] Multiple springs 9 are fixedly connected to the side of the mounting plate 6 near the inner wall of the circular groove 5. The ends of the springs 9 are slidably connected to the inner wall of the circular groove 5. Multiple spring grooves are provided on the inner wall of the circular groove 5 on the side wall of the flange 3. The ends of the multiple springs 9 away from the mounting plate 6 are installed inside the spring grooves. Thanks to the setting of multiple springs 9, when the screw 4 between the two flanges 3 is removed, the multiple springs 9 will automatically push the mounting plate 6 out of the circular groove 5, so as to facilitate pulling the mounting plate 6 to pull out the curved blade 7. At the same time, thanks to the setting of spring grooves, when the two flanges 3 are installed by the screw 4 and the flanges 3 are squeezed, the springs 9 will retract into the spring grooves to prevent the springs 9 from being squeezed and damaged.
[0031] The side walls of the curved blades 7 are all fixedly bonded with sealing strips 10. The outer wall of the sealing strips 10 slides against the inner wall of the mixing tube 1. Thanks to the setting of the sealing strips 10, the sealing effect between the outer wall of the curved blades 7 and the inner wall of the mixing tube 1 can be further improved, and the curved blades 7 can be further prevented from being damaged by friction between the curved blades 7 and the inner wall of the mixing tube 1 during installation.
[0032] A sealing ring 11 is fixedly bonded to the outer wall of the insertion tube 8. The outer wall of the sealing ring 11 is sealed and fitted to the inner wall of the mixing tube 1. Thanks to the setting of the sealing ring 11, the sealing performance between the insertion tube 8 and the inner wall of the mixing tube 1 is further improved.
[0033] The arc angles of two adjacent curved blades 7 are set in opposite directions, and when multiple curved blades 7 are connected, the angles are set in opposite directions. This can further improve the mixing efficiency of multiple liquids and thus improve the uniformity of the mixing of multiple liquids.
[0034] The mixing tube 1 and the multiple curved blades 7 are all made of 316L stainless steel. Thanks to the fact that the mixing tube 1 and the curved blades 7 are made of 316L stainless steel, corrosion can be reduced, thereby increasing service life.
[0035] Working principle
[0036] When using this corrosion-resistant mixer, if it is necessary to disassemble, clean, or replace the curved blade 7, first remove the two flanges 3 that are installed by the screws 4. At this time, the mounting plate 6 installed inside the circular groove 5 opened on the side wall of the flange 3 will be ejected from the inside of the circular groove 5 by multiple springs 9. Then, the mounting plate 6, the insertion pipe 8, and the curved blade 7 can be pulled out of the mixing pipe 1.
