Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment agent mixing device. Background Technology

[0002] With the advancement of science, the number of factories in my country has gradually increased, and the discharge of industrial wastewater has also increased significantly. Industrial wastewater contains harmful substances that can damage the environment. According to national regulations, wastewater needs to be treated to meet discharge requirements before it can be discharged. During wastewater treatment, chemicals need to be added to decompose the harmful substances contained in the wastewater. However, existing wastewater treatment chemical mixing devices only use a single stirring rod for mixing, resulting in poor mixing effect, low mixing rate, and insufficient mixing of chemicals. Utility Model Content

[0003] The purpose of this invention is to solve the problems of poor mixing effect, low mixing rate, and insufficient mixing of chemicals caused by the use of a single stirring rod in existing sewage treatment chemical mixing devices.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: It provides a wastewater treatment agent mixing device for wastewater treatment, comprising a mixing tank. A first annular partition is installed inside the mixing tank, and a second annular partition is connected to the outer side of the first annular partition. An air bladder is provided inside the first annular partition. An air pump connected to the air bladder via a connecting pipe is provided on one side of the mixing tank. A motor is installed at the top center of the mixing tank. The output end of the motor passes through the top plate of the mixing tank and is fixedly connected to a first stirring rod and a second stirring rod arranged in a cross configuration. The first stirring rod is located inside the first annular partition, and the second stirring rod is located between the outer wall of the second annular partition and the inner wall of the mixing tank.

[0005] Furthermore, three vertical first connecting plates are evenly provided at equal angles at the bottom of the first annular partition, and each first connecting plate is fixedly connected to the inner bottom surface of the mixing tank.

[0006] Furthermore, the bottom surface of the second annular partition is higher than the bottom surface of the first annular partition, and three horizontal second connecting plates are evenly provided at equal angles at the bottom of the second annular partition, each of which is fixedly connected to the outer wall of the first annular partition.

[0007] Furthermore, the angle formed by the intersection of the first stirring rod and the second stirring rod is 90°.

[0008] Furthermore, the bottom of the mixing tank is provided with a discharge pipe, and a valve is installed on the discharge pipe.

[0009] Furthermore, a hopper is installed on the top surface of the mixing tank.

[0010] Furthermore, the airbag is made of fluororubber or silicone rubber to resist chemical corrosion.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model separates the wastewater treatment agents by using a first annular baffle and a second annular baffle inside the mixing tank, and uses the reciprocating airbags and intersecting stirring rods inside to stir the agents, thereby enhancing the flow of the agents and ensuring that the agents are fully mixed and maintain uniformity.

[0013] 2. The first and second stirring rods driven by motors can easily stir the medicine in the mixing tank, and the use of an air pump makes it easier to control the mixing process.

[0014] 3. Airbags made of fluororubber or silicone rubber have excellent corrosion resistance, effectively resisting the corrosion of chemicals and extending the service life of the equipment. The combination of motor drive and air pump supply can utilize energy more effectively, reduce energy consumption, and reduce operating costs compared to traditional mechanical drive methods.

[0024] Combination Figures 1 to 5 The wastewater treatment agent mixing device shown includes a mixing tank 1. A first annular baffle 2 is installed inside the mixing tank 1. A second annular baffle 3 is connected to the outside of the first annular baffle 2. An air bladder 4 is provided inside the first annular baffle 2. An air pump 5 is provided on one side of the mixing tank 1 and is connected to the air bladder 4 through a connecting pipe. A motor 6 is installed at the middle of the top of the mixing tank 1. The output end of the motor 6 passes through the top plate of the mixing tank 1 and is fixedly connected to a first stirring rod 7 and a second stirring rod 8 arranged in a cross pattern. The first stirring rod 7 is located inside the first annular baffle 2, and the second stirring rod 8 is located between the outer wall of the second annular baffle 3 and the inner wall of the mixing tank 1.

[0025] The first annular partition 2 has three vertical first connecting plates 21 evenly spaced at equal angles at its bottom, and each first connecting plate 21 is fixedly connected to the inner bottom surface of the mixing tank 1; the bottom surface of the second annular partition 3 is higher than the bottom surface of the first annular partition 2, and the bottom surface of the second annular partition 3 has three horizontal second connecting plates 31 evenly spaced at equal angles, and each second connecting plate 31 is fixedly connected to the outer wall of the first annular partition 2; the first stirring rod 7 and the second stirring rod 8 intersect at an angle of 90°; the bottom of the mixing tank 1 is provided with a discharge pipe 9, and a valve 10 is installed on the discharge pipe 9; a hopper 11 is installed on the top surface of the mixing tank 1; the airbag 4 is made of fluororubber or silicone rubber to resist chemical corrosion.

[0026] Working principle: During use, various wastewater treatment agents are added into the mixing tank 1 from the hopper 11. Then, the motor 6 is started to drive the first stirring rod 7 and the second stirring rod 8 to rotate. At the same time, the air pump 5 is started to inflate and de-inflate the air bag 4 through the connecting pipe. As a result, the air bag 4 expands and contracts. During expansion and contraction, the agents in the mixing tank 1 are continuously tumbled and flowed. The first annular baffle 2 and the second annular baffle 3 enhance the flow force of the agents impacting and tumbling, thereby increasing the mixing rate of the agents. After the mixing is completed, the mixed agents can be discharged by opening the valve 10.
