Description

Technical Field

[0001] The utility model mainly relates to the technical field of chemical wastewater detection, in particular to a chemical drainage pipeline wastewater detection device. Background Art

[0002] Pure water changes its original physical or chemical properties after use, and becomes sewage containing different kinds of impurities. Chemical sewage is sewage such as process sewage, cooling water, exhaust gas washing water, equipment and site washing water discharged in chemical production. If these sewage are discharged without treatment, they will cause different properties and different degrees of pollution in the water body, thereby endangering human health and affecting industrial and agricultural production. The treated chemical sewage is usually discharged through drainage pipes. Therefore, it is often necessary to test chemical sewage to find out whether the components of the discharged sewage meet the discharge standards.

[0003] After searching, it is found that the utility model patent with announcement number CN212060212U discloses a sewage detection device for chemical drainage pipes, including a main pipe, a filter chamber is opened at the bottom of one end of the main pipe, a rotating frame is arranged inside the filter chamber, the internal rotation of the rotating frame is connected to a rotating shaft, a plurality of adjustment seats are arranged in a ring outside the rotating shaft, the internal rotation of the adjustment seat is connected to a paddle, the lower end of the rotating frame is connected to a screw rod through a bearing, and the other end of the screw rod is threaded through the bottom of the filter chamber. In this patent, the screw rod drives the rotating frame to rotate inside the filter chamber, which is convenient for rotating through the paddle, thereby intercepting solid impurities in the sewage on the cover plate, and transporting and accumulating them inside the filter chamber through the cover plate, which is convenient for intercepting and detecting solid impurities in the sewage. The absorption chamber design is convenient for collecting and detecting the sewage transported in the pipeline, and transporting it to the collection bottle for sample detection, which is simple, practical and convenient.

[0004] In the above patented technical solution, the rotating frame is driven by a screw to rotate inside the filter chamber, which is convenient for rotating the paddle, so that the solid impurities in the sewage are intercepted on the cover plate, and transported and accumulated inside the filter chamber through the cover plate, which is convenient for intercepting and detecting the solid impurities in the sewage. The absorption chamber design is convenient for collecting and testing the sewage transported in the pipeline, and transporting it to the collection bottle for sample detection, which is simple, practical and convenient. However, the above patented technical solution still has the following shortcomings when used:

[0005] 1. When the above patented technical solution is used, the sewage in the pipeline is extracted by pulling the piston. However, the collection bottle in the above patented technical solution does not have a sealing measure, which causes the sewage in the collection bottle to be easily oxidized by the outside air during the process of being sent to the test, affecting the accuracy of the sewage test results;

[0006] 2. When the above patented technical solution is used, the solid impurities in the sewage are intercepted on the cover plate by the rotation of the paddle, and are transported and accumulated inside the filter chamber by the cover plate. However, the paddle and the cover plate in the above patented technical solution are easily damaged by the impact of solid particles for a long time. When the paddle and the cover plate are damaged, the paddle and the cover plate in the above patented technical solution are not convenient for quick installation and removal, resulting in a decrease in the service life of the device;

[0007] Therefore, we provide a chemical drainage pipe sewage detection device to solve the defects existing in the above-mentioned patent technical solution. Utility Model Content
