Description

Technical Field

[0001] The utility model belongs to the technical field of SBR, and particularly relates to a sampling device for an SBR reactor. Background Technique

[0002] SBR is the abbreviation of Sequencing Batch Reactor, which is an activated sludge sewage treatment technology operated in an intermittent aeration mode. Its main feature is the orderly and intermittent operation in operation. The core of the SBR technology is the SBR reaction tank, which integrates functions such as equalization, primary sedimentation, biodegradation, and secondary sedimentation in one tank, without a sludge return system. It is particularly suitable for occasions with insufficient construction space, intermittent discharge, and large flow variations.

[0003] During the SBR reaction process, sampling and detection are required. The existing sampling methods are inconvenient to operate. It is necessary to hold a sampler for sampling operations, which is inconvenient for operation and has a high sampling difficulty. For this reason, we propose a sampling device for an SBR reactor. Summary of the Utility Model

A C-shaped pipeline structure is formed among the upper sampling pipe, the column observation pipe, the tee, and the lower sampling pipe. A butterfly valve I and a gas guiding valve are arranged on the upper sampling pipe. Two butterfly valves II are arranged on the lower sampling pipe. A pipeline circulation pump is installed on the lower sampling pipe between the two butterfly valves II.

[0006] By adopting the above solution, a C-shaped pipeline structure is formed by cooperating with the upper sampling pipe, the lower sampling pipe, and the column observation pipe and installed on the side wall of the SBR reactor box. The upper sampling pipe extends into the middle position inside the water tank to ensure that the sampling position is in the middle of the water tank. A pipeline circulation pump is installed on the lower sampling pipe to ensure that the mixture in the pipeline can circulate. The butterfly valve I and the butterfly valve II are used in cooperation to cut off the flowing water in the pipeline in time. The high-transparency quartz glass is used as the column observation pipe, and after precipitation, the sludge precipitation volume can be measured. The setting of the tee can control the outflow of the mixture to ensure manual sampling and detection. By setting a heat preservation sleeve, it can ensure that too much temperature will not be lost when the sampled material is discharged, and the heat preservation effect is good.

[0007] In the above solution, it should be noted that the pipeline circulation pump is electrically connected to an external power supply.

[0012] As a preferred embodiment, heat insulation sleeves are sleeved on the outer surfaces of the upper sampling pipe, the column observation pipe, and the lower sampling pipe, and an observation opening is provided on the heat insulation sleeve located outside the column observation pipe.

[0013] With the above solution, the setting of the heat insulation sleeve can achieve a good heat insulation effect, and the observation opening provided on the heat insulation sleeve of the column observation pipe can facilitate viewing the sample situation inside the column observation pipe.

[0014] As a preferred embodiment, the bottom end of the three-way pipe is specifically a manual sampling port, and the surface of the manual sampling port has threads and a sealing cover is threadedly installed.

[0025] A three-way pipe 13 is connected and installed at the left end of the lower sampling pipe 4. The upper port of the three-way pipe 13 and the left end of the upper sampling pipe 2 are respectively detachably connected to the bottom end and the top end of the column observation pipe 3. A C-shaped pipeline structure is formed among the upper sampling pipe 2, the column observation pipe 3, the three-way pipe 13 and the lower sampling pipe 4. A first butterfly valve 5 and an air guide valve 6 are arranged on the upper sampling pipe 2. The setting of the air guide valve 6 can discharge the redundant gas in the pipeline before operation.

[0026] Two second butterfly valves 8 are arranged on the lower sampling pipe 4. A pipeline circulation pump 7 is installed on the lower sampling pipe 4 between the two second butterfly valves 8. By setting the pipeline circulation pump 7, it can ensure a large flow rate and facilitate flushing the observation pipe and the precipitated sludge in the pipeline.

[0027] By setting up the upper sampling pipe 2, the lower sampling pipe 4 and the column observation pipe 3 to form a C-shaped pipeline structure and installing it on the side wall of the SBR reactor box body, the upper sampling pipe 2 extends into the middle position inside the water pool to ensure that the sampling position is in the middle of the water pool. The lower sampling pipe 4 is installed with a pipeline circulation pump 7 to ensure that the mixture in the pipeline can circulate. The first butterfly valve 5 and the second butterfly valve 8 are used in cooperation to cut off the flowing water in the pipeline in time. The high-transparency quartz glass is used as the column observation pipe 3, which can measure the volume of sludge precipitation after precipitation. The setting of the three-way pipe 13 can control the outflow of the mixture to ensure manual sampling and detection. By setting up the heat preservation sleeve 11, it can ensure that too much temperature will not be lost when the sampled material is discharged, and the heat preservation effect is good.

[0028] Welding plates 9 are fixedly installed on the outer surfaces of both the upper sampling pipe 2 and the lower sampling pipe 4. The setting of the welding plates 9 can effectively weld and fix the upper sampling pipe 2 and the lower sampling pipe 4 after they are inserted into the SBR reactor, improving the stability of welding and installation.

[0029] Tube furnace quick-release vacuum flanges 10 are installed at both the top and bottom of the column observation pipe 3. The two tube furnace quick-release vacuum flanges 10 are respectively movably connected to the upper sampling pipe 2 and the three-way pipe 13. The tube furnace quick-release vacuum flanges 10 are used to realize the quick-release and quick-installation operations of the upper sampling pipe 2 and the three-way pipe 13.

[0030] Heat preservation sleeves 11 are sleeved on the outer surfaces of the upper sampling pipe 2, the column observation pipe 3 and the lower sampling pipe 4. There is an observation opening on the heat preservation sleeve 11 located outside the column observation pipe 3. The setting of the heat preservation sleeve 11 can achieve a good heat preservation effect. The observation opening of the heat preservation sleeve 11 on the column observation pipe 3 is set to facilitate viewing the sample situation inside the column observation pipe 3.

[0031] The bottom end of the three-way pipe 13 is specifically a manual sampling port, and the surface of the manual sampling port has threads and a sealing cover 12 is threadedly installed. The setting of the sealing cover 12 facilitates the manual sampling and discharging operation. The threaded connection has good sealing performance, is not easy to loosen, and has high connection stability.

[0033] During use, the upper sampling tube 2 and the lower sampling tube 4 respectively penetrate into the SBR reactor, and the welding plate 9 is used to fit against the side of the SBR reactor and is welded and fixed to the side of the SBR reactor. At this time, the upper sampling tube 2 penetrates into the middle position inside the SBR reactor, and the sampling position is ensured to be in the exact center. The pipeline circulation pump 7 installed on the lower sampling tube 4 can ensure the stable circulation of the mixture in the pipeline. The butterfly valve I 5 on the upper sampling tube 2 and the butterfly valve II 8 on the lower sampling tube 4 can conveniently cut off the flowing material in the pipeline in a timely manner. The highly transparent adaptable glass material is used as the column observation tube 3, which can facilitate a clear view of the sludge sedimentation situation. At the same time, the column observation tube 3 can achieve a convenient disassembly and assembly operation through the tube furnace quick-release vacuum flange 10, which is convenient for replacement and maintenance. When manually sampling and discharging materials, only need to turn the sealing cover 12 and remove the sealing cover 12 to discharge the materials in the pipeline. The setting of the heat preservation sleeve 11 on the cylinder cover can ensure that the temperature of the materials in the pipeline will not be lost too much.
