Description

Technical Field

[0001] The utility model relates to the technical field of hydrolyzers, in particular to a multi-channel automatic hydrolyzer sewage sampling and analysis device. Background Art

[0002] The automated urea hydrolyzer hydrolyzes urea into ammonia and carbon dioxide, and produces a certain amount of sewage. Sewage is ammonia-containing wastewater produced during the hydrolysis process. For environmentally friendly discharge, the ammonia-containing wastewater needs to be tested.

[0003] In related technologies, instruments are often used to detect ammonia-containing wastewater. After collecting relevant information and searching, we discovered an online air detection and alarm device (Announcement No. CN220491421U) that requires no wiring. This device uses different detection sensors to detect different gases. During testing, the gas detector's chamber is connected to the pipeline, commonly using a plug-in seal or a threaded connection.

[0004] However, although this installation method is more convenient to install, if the wastewater discharged from the pipeline contains impurities, the impurities will adhere to the gas chamber of the gas detector after long-term use, resulting in reduced detection accuracy or detection errors. During maintenance, it is necessary to temporarily close the valve of the pipeline and then replace or clean the gas detector, which delays the discharge of wastewater and easily accelerates the damage of the gas detector. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-channel automated hydrolyzer sewage sampling and analysis device to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a multi-channel automated hydrolyzer sewage sampling and analysis device, comprising a first flange pipe fitting, the upper end of which is connected to a valve, and the upper end of which is provided with a second flange pipe fitting;

[0007] The upper end of the second flange pipe is connected to a detection alarm, a sealing sleeve is installed between the second flange pipe and the detection alarm, a support is placed inside the sealing sleeve, a filter cartridge is placed in the support, and a detection end of the detection alarm is inserted into the filter cartridge;

[0008] Using a filter cartridge to separate and protect the detection end of the detection alarm can prevent impurities from adhering to the detection end and extend the service life of the detection alarm.

[0009] Furthermore, the support member is arranged in a T shape, and an annular groove is provided on the upper surface of the support member. The upper end of the filter cartridge is provided with an anti-fall ring, and the anti-fall ring is placed inside the annular groove. A limiting cylinder is provided on the lower part of the surface of the detection alarm, and a clamping block is provided on the inner wall of the limiting cylinder. The clamping block is pressed on the surface of the anti-fall ring to improve the stability of the filter cartridge installation, ensure that the filter cartridge will not move, prevent the filter cartridge from contacting the detection end, and will not damage the detection alarm.

[0010] Furthermore, a fixing hole seat is provided on the upper surface of the detection alarm device, and screws can be used to assist in fixing the detection alarm device to improve the stability of the installation.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] (1) A sealing sleeve is provided between the detection alarm and the second flange pipe fitting, and a filter cartridge is placed on the support member in the sealing sleeve so that the sealing sleeve seals the filter cartridge to prevent air leakage. The detection end of the detection alarm is inserted into the filter cartridge, and impurities are blocked by the filter cartridge to prevent impurities from clogging the detection end and damaging the detection end, thereby improving the detection accuracy of the detection alarm and extending its service life.

[0013] (2) Closing the valve can prevent air leakage from the first flange pipe fitting. Then the sealing sleeve can be removed, and the detection alarm and filter cartridge can be taken out for cleaning. There is no need to close the main valve of the pipeline, which will not affect the discharge of wastewater. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Example:

[0022] See also Figure 1-5 The utility model provides a technical solution: a multi-channel automated hydrolyzer sewage sampling and analysis device, comprising a first flange pipe 1, the upper end of which is connected to a valve 2, the upper end of which is provided with a second flange pipe 3, the first flange pipe 1 having threads and can be screwed to a sewage pipe, and the valve 2 can block the first flange pipe 1 to prevent leakage;

[0023] The upper end of the second flange pipe 3 is connected to a detection alarm 6, a sealing sleeve 4 is installed between the second flange pipe 3 and the detection alarm 6, a support member 10 is placed inside the sealing sleeve 4, a filter cartridge 9 is placed in the support member 10, and the detection end of the detection alarm 6 is inserted into the filter cartridge 9;

[0024] The sealing sleeve 4 is clamped by the second flange pipe 3 and the detection alarm 6, which can seal the filter cartridge 9 to prevent leakage.

[0025] In this embodiment, if Figure 2 As shown, the support member 10 is arranged in a T shape, and an annular groove 11 is provided on the upper surface of the support member 10. The support member 10 limits the filter cartridge 9 to prevent the filter cartridge 9 from falling into the deep of the second flange pipe 3.

[0026] In this embodiment, if Figure 2 As shown, the upper end of the filter cartridge 9 is provided with an anti-fall ring 8, and the anti-fall ring 8 is placed inside the annular groove 11, which can limit the filter cartridge 9 and also facilitate the use of the anti-fall ring 8 to remove the filter cartridge 9.

[0027] In this embodiment, if Figure 2 and Figure 3 As shown, a limiting cylinder 7 is provided on the lower part of the surface of the detection alarm 6, and a clamping block 12 is provided on the inner wall of the limiting cylinder 7. The clamping block 12 is pressed on the surface of the anti-fall ring 8 to prevent the filter cylinder 9 from floating up and down and will not move after installation.

[0029] Specifically, when in use, after the first flange pipe 1 is screwed to the sewage pipe, the valve 2 is opened, and the polluted gas in the pipe enters the first flange pipe, the valve 2, and the second flange pipe 3. The polluted gas passes through the filter cartridge 9 and is detected by the detection end of the detection alarm 6. When impurities are mixed in the polluted gas, the filter cartridge 9 can block the impurities, and the filter cartridge 9 does not contact the detection end, ensuring that the detection end will not be attached by impurities;

[0030] When the detection alarm 6 fails to detect accurately, it is necessary to clean the detection alarm 6 and the filter cartridge 9. First, close the valve 2 to prevent the leakage of contaminated gas.
