Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a tail seat of a high-efficiency sewage treatment ejector. Background Art

[0002] The aeration and oxygenation of the aerobic section of general sewage treatment include microporous aeration, submersible aeration, surface aeration machine, etc. Aerobic biological treatment is the preferred process for treating urban sewage, domestic sewage, and low-concentration industrial organic wastewater. At present, there are two types of aeration: mechanical aeration and blast aeration. Mechanical aeration is other mechanical equipment that sends air into the water through mechanical devices, such as rotating brushes, inverted umbrella-shaped impellers, etc. Mechanical aeration is easy to operate and maintain, but the energy consumption is relatively high.

[0003] In the use of existing sewage treatment ejectors, the inner surface stain cleaning structures at the connection positions are difficult to disassemble. When these structures need to be cleaned or replaced due to long-term use or improper maintenance, the complicated disassembly process not only increases the labor intensity of the staff, but may also cause damage to other components during the disassembly process, further reducing the working efficiency of the ejector.

[0025] Reference Figure 1-Figure 3 , which is an embodiment of the utility model, provides a high-efficiency sewage treatment ejector tail seat, including a main unit 100, a mounting unit 200 and a cleaning unit 300.

[0026] The main unit 100 includes a tailstock body 101 and a nozzle 102 matched with the tailstock body 101. A connecting pipe 103 is fixedly installed on one side of the nozzle 102 away from the tailstock body 101. The high-pressure water flow sprayed by the nozzle 102 can effectively wash away impurities such as solid particles and suspended matter in the sewage and separate them from the water.

[0027] The mounting unit 200 includes a first connecting block 202 symmetrically fixedly mounted on the outer surface of the connecting tube 103, a first telescopic spring 204 is fixedly mounted on the side of the first connecting block 202 away from the tailstock body 101, and a second connecting block 203 is fixedly mounted on the side of the first telescopic spring 204 away from the first connecting block 202, a limiting ring 201 is fixedly mounted on the opposite surface of the two groups of second connecting blocks 203, a clamping block 205 is symmetrically mounted on the side of the limiting ring 201 close to the connecting tube 103, and a clamping groove 206 is symmetrically opened on the side of the connecting tube 103 close to the limiting ring 201, and the clamping groove 206 is clamped with the clamping block 205, and the hand fits the limiting ring 201. The outer surface of the ring 201 is pulled away from the tailstock body 101. During the movement of the limiting ring 201, the first telescopic spring 204 is stretched and engaged with the limiting groove 208 through the cross plate 207, and the pulling of the limiting ring 201 is cancelled. The first telescopic spring 204 rebounds, so that the block 205 is inserted into the groove 206, so that the surface of the connecting pipe 103 fits with the surface of the limiting ring 201. The limiting ring 201 limits the cross plate 207, and the installation of the cleaning unit 300 is completed. When disassembly is required, the limiting ring 201 is pulled to disassemble the cleaning unit 300. The operation is simple and quick, which improves the working efficiency of the injector.

[0028] The inner cavity of the connecting pipe 103 is symmetrically provided with limiting grooves 208 , and the inner cavity of the limiting grooves 208 is clamped with a transverse plate 207 , and the installation of the cleaning unit 300 is completed through the transverse plate 207 .

[0029] The cleaning unit 300 includes a rotating shaft 301 fixedly mounted on one side of the transverse plate 207, a connecting plate 303 is symmetrically mounted on the surface of the rotating shaft 301, a supporting plate 304 is fixedly mounted on the side of the connecting plate 303 away from the rotating shaft 301, and a scraper 307 is arranged on the side of the supporting plate 304 away from the connecting plate 303. When the rotating shaft 301 rotates, the supporting plate 304 is driven to rotate by the rotating shaft 301, and the scraper 307 is driven to rotate by the supporting plate 304, so as to protect and clean the inner surface of the connecting pipe 103, so that the injector can continue to work efficiently, thereby improving the working efficiency of the injector.

[0030] Telescopic spring tubes 305 are symmetrically installed on the opposite surfaces of the supporting plate 304 and the scraper 307. The outer surface of the telescopic spring tube 305 is sleeved with a second telescopic spring 306, and the two ends of the second telescopic spring 306 are respectively fixedly connected to one side of the supporting plate 304 and the scraper 307. The telescopic spring tube 305 and the second telescopic spring 306 drive the scraper 307 to telescope, so that the scraper 307 can fit with the inner wall of the connecting tube 103, thereby improving the cleaning efficiency.

[0031] A fan blade 302 is fixedly mounted on one end of the rotating shaft 301 , and the fan blade 302 is located on the right side of the horizontal plate 207 . When the ejector is connected to a water source and starts working, the impact force of the water source drives the fan blade 302 to rotate, and the fan blade 302 drives the rotating shaft 301 to rotate.

[0032] The scraper 307 is arc-shaped, and the side of the scraper 307 away from the rotating shaft 301 is in contact with the inner wall of the connecting tube 103. The outer surface of the scraper 307 is in contact with the inner wall of the connecting tube 103, thereby improving the cleaning effect.

[0033] During use, the limiting ring 201 is pulled in the direction away from the tailstock body 101. During the movement of the limiting ring 201, the first telescopic spring 204 is stretched, and the cross plate 207 is engaged with the limiting groove 208, and the pulling of the limiting ring 201 is cancelled. The first telescopic spring 204 rebounds, and the clamping block 205 is inserted into the clamping groove 206, so that the surface of the connecting pipe 103 fits with the surface of the limiting ring 201. The limiting ring 201 limits the cross plate 207, and the installation of the cleaning unit 300 is completed. When it needs to be disassembled, , the cleaning unit 300 can be disassembled by pulling the limit ring 201. The operation is simple and quick, which improves the working efficiency of the injector. When the injector is connected to the water source and starts working, the impact force of the water source drives the fan blades 302 to rotate, and the fan blades 302 drive the rotating shaft 301 to rotate, and the rotating shaft 301 drives the supporting plate 304 to rotate, and the supporting plate 304 drives the scraper 307 to rotate, and the inner surface of the connecting pipe 103 is protected and cleaned, so that the injector can continue to work efficiently, thereby improving the working efficiency of the injector.
