Description

Technical Field

[0001] This utility model relates to the field of aeration technology, and in particular to a novel flat-plate aeration device. Background Technology

[0002] As wastewater treatment effluent standards become increasingly stringent, the requirements for energy-saving equipment used in wastewater treatment are also rising. Among these, microporous aeration devices are one of the key pieces of equipment in wastewater treatment.

[0003] Microporous aeration devices refer to aeration devices that use a blower to send air into an air delivery pipeline, and then use specially designed microporous strips to evenly disperse the air into the water in the form of microbubbles. Currently, the most commonly used microporous aeration devices include corundum aeration devices and rubber membrane aeration devices, but they all have problems such as low efficiency and short service life. After long-term use, they become clogged and difficult to clean, requiring disassembly and cleaning, resulting in high operating costs.

[0004] Therefore, we propose a novel flat-plate aeration device. Utility Model Content

[0012] In a preferred embodiment of this utility model, the diversion structure further includes springs, with a spring sleeved near both ends of the connecting shaft, and the springs are capable of abutting against the strips near the inner wall of the outer casing.

[0013] In a preferred embodiment of this utility model, the slats are divided into two groups, which are mirror images of each other with the air supply pipe as the axis. A gap is left between the two groups of slats, and a limiting block that is fixedly connected to the bottom of the outer shell is provided in the gap.

Beneficial effects

[0016] This invention provides a novel flat-plate aeration device. It has the following beneficial effects:

[0017] 1. This novel flat-plate aeration device boasts a high oxygen utilization rate, 1.5 times that of traditional aeration devices, and low resistance loss, at 50% of that of traditional aeration devices. It exhibits excellent energy-saving performance, with an energy saving rate exceeding 30% compared to the adjustable plate type.

[0025] A novel flat-plate aeration device, such as Figure 1 and Figure 2 As shown, it includes:

[0026] The outer casing 10 has an internal cavity. Specifically, the outer casing 10 is a rectangular box. The top of the outer casing 10 is provided with a top cover fixed by screws. The bottom of the outer casing 10 is provided with an air supply pipe 12 for supplying air to the cavity. Several injection holes 11 are opened on the top of the outer casing 10, and the injection holes 11 are opened on the top cover and near both ends.

[0027] like Figure 3 and Figure 4 As shown, a flow-diverting structure is installed inside the outer casing 10 to cut and guide the gas. The flow-diverting structure includes a connecting shaft 20, slats 21, and grooves 22. The connecting shaft 20 is fixedly installed to the outer casing 10. The connecting shaft 20 is provided with several slats 21 that can slide radially along the connecting shaft 20. One slat 21 near the side wall of the outer casing 10 is elastically connected to the outer casing 10. Each slat 21 has grooves 22 for gas flow. The outer casing 10 forms a box structure. The connecting shaft 20 is cylindrical. Each slat 21 has two through holes that fit the connecting shaft 20. Two connecting shafts 20 are symmetrically arranged on the inner wall of the outer casing 10. The connecting shafts 20 are slidably disposed in the through holes. The slats 21 form a connection with the outer casing 10. The shell 10 has plates of equal width and height in the chamber. The grooves 22 are rectangular grooves. A grate for cutting gas is formed between two adjacent grooves 22. The grooves 22 of two adjacent plates 21 are staggered. The diversion structure also includes springs 23. A spring 23 is sleeved near both ends of the connecting shaft 20. The springs 23 can abut against the plates 21 near the inner wall of the shell 10. The plates 21 are divided into two groups. The two groups of plates 21 are mirrored with the air supply pipe 12 as the axis. There is a gap between the two groups of plates 21. A limiting block is provided in the gap and fixedly connected to the bottom of the shell 10. The shell 10 and the plates 21 can be made of ABS material, and the connecting shaft 20 and the springs 23 can be made of stainless steel.

[0028] In this design, the air pipe 12 connects to an air source, such as a gas cylinder. Compressed air is delivered through the air pipe 12 between the two sets of slats 21. A baffle ensures that a gap is formed between the two sets of slats 21 to allow air to enter. The air is cut and diverted by grooves 22 on the sidewalls of multiple slats 21 and delivered into the chambers near the sides of the outer shell 10. Then, it is ejected from multiple injection holes 11 to form bubbles and achieve an aeration effect. At the same time, the air can push the slats 21 to slide radially along the connecting shaft 20 to adapt to the air pressure. A gap is formed between two adjacent connecting shafts 20 under the action of compressed air. A slat near the inner sidewall of the outer shell 10... Strip 21 compresses the spring 23 to deform, while the injection hole 11 is opened on one side of the outermost strip 21 to ensure exhaust. This solution has a high oxygen utilization rate, which is 1.5 times that of traditional aeration devices. The resistance loss is low, which is 50% of that of traditional aeration devices. It has a good energy-saving effect, with an energy saving rate of more than 30% compared to the regulating plate. The material is made of nylon composite material, which has good aging resistance, is not easy to clog, and has a long service life, which is twice that of traditional rubber membrane aerators. It has a self-cleaning device that can automatically adjust the gap between the strips according to the internal clogging pressure, eliminating the need for chemical cleaning agents used in traditional aeration devices. Operation and maintenance are simple.

[0029] like Figure 4 and Figure 5 As shown, the adjustment component is provided on the side wall of the housing 10 for adjusting the position of the slats 21;

[0030] The adjustment assembly includes an adjustment plate 30 and an adjustment screw 31. The adjustment plate 30 is slidably connected to the connecting shaft 20. The adjustment screw 31 can push the adjustment plate 30 to compress the spring 23. The adjustment plate 30 is a rectangular plate. The spring 23 is located between the adjustment plate 30 and the plate strip 21. A threaded sleeve is fixedly provided on the outer wall of the housing 10. The adjustment screw 31 is threadedly connected to the threaded sleeve and rotatably connected to one side of the adjustment plate 30. The adjustment plate 30 can approach the plate strip 21 to compress the spring 23 and deform it.

[0031] In this scheme, as a supplement to the above scheme, by rotating the adjusting screw 31, the adjusting screw 31 pushes the adjusting plate 30 to slide along the connecting shaft 20, while the spring 23 is located between the plate 21 and the adjusting plate 30. By the adjusting plate 30 compressing the spring 23 to deform it, the pre-compression value of the spring 23 is adjusted. Thus, the pushing force of the spring 23 on the plate 21 can be adjusted within a certain range. The compression state of the spring 23 can be adjusted according to the air pressure and aeration effect, which has stronger controllability and adjustability.

[0032] The working principle of this utility model is as follows: Compressed air is delivered into the space between two sets of slats 21 through the air supply pipe 12. A baffle ensures a gap between the two sets of slats 21 to allow air to enter. The air is cut and diverted by grooves 22 on the side walls of multiple slats 21 and delivered into the chambers near both sides of the outer casing 10. Then, it is ejected from multiple injection holes 11 to form bubbles, achieving an aeration effect. Simultaneously, the air pushes the slats 21 to slide radially along the connecting shaft 20 to adapt to the air pressure. A gap is formed between adjacent connecting shafts 20 under the action of compressed air. A slat 21 near the inner wall of the outer shell 10 compresses the spring 23 to deform, while the injection hole 11 is opened on one side of the outermost slat 21 to ensure exhaust. Rotating the adjusting screw 31 pushes the adjusting plate 30 to slide along the connecting shaft 20. The spring 23 is located between the slat 21 and the adjusting plate 30. The adjusting plate 30 compresses the spring 23 to deform it, adjusting the pre-compression value of the spring 23. Thus, the pushing force of the spring 23 on the slat 21 can be adjusted within a certain range. The compression state of the spring 23 can be adjusted according to the air pressure and aeration effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
