Description

Technical Field

[0001] The utility model relates to the technical field of power supply, in particular to a conductive slip ring dedicated to central transmission type mud scraper cleaning equipment. Background Art

[0002] The secondary sedimentation tank of a sewage treatment plant is a secondary sedimentation tank. It is an important component of the activated sludge system. Its main function is to separate mud and water, clarify, concentrate and return the activated sludge to the mixed liquid. Large and medium-sized sewage treatment plants mostly use circular radial flow sedimentation tanks with mechanical sludge suction. At present, they mainly use two types of sludge suction and scraping equipment, namely central transmission scraper and peripheral transmission scraper, to solve the power source of the existing central transmission scraper cleaning equipment. At present, on the central transmission scraper, whether it is mechanical washing, roller brush washing or forced brush washing, or high-pressure water pump flushing, it is necessary to first solve the power supply problem of the moving equipment. The only difficulty in the central transmission system is to solve the power supply, because the power supply cannot be placed in the center, there will be entanglement. The design source of the present invention is to infinitely enlarge the center origin to achieve non-interference and non-entanglement, so that the wire will not be biased and the above problems will not occur. At the same time, the installation position needs to be below the maintenance bridge to avoid interference between the slip ring and the equipment itself.

[0003] The conductive slip rings of the prior art are less affected when used in the summer when there is not much water vapor. However, in the autumn and winter in the north, especially in the secondary sedimentation tank, the temperature difference between the water temperature and the ambient temperature is large. The entire tank will be shrouded in water mist, and a large amount of dew, frost, and even ice will be produced. This may cause poor sliding, damage between the slip ring and the carbon brush holder (electric receiver), and even power outages and short circuits in the circuit, posing a major safety hazard.

[0010] As an improvement, a current collector is arranged inside the slide rail.

[0011] Compared with the prior art, the utility model has the following advantages: in order to make the conductive slip ring operate stably and safely in autumn and winter, it is necessary to ensure that the slip ring has a certain function of removing dew and frost. The utility model installs a heating belt in the empty groove on the upper part of the slip ring, and the heating belt is connected to the power supply through a control switch to achieve controllable temperature in summer and winter.
