Background

The pollutant adsorption capacity generally refers to the adsorption strength of the adsorbent on pollutants in a water body. At present, the device instrument of survey pollutant adsorption affinity is exclusively used in generally is the pollutant adsorption affinity monitor, and it includes a monitoring section of thick bamboo, loads the adsorbent in the monitoring section of thick bamboo, and a monitoring section of thick bamboo both ends communicate inlet tube and outlet pipe respectively, go out water piping connection collecting box, and water quality monitoring device is connected to the collecting box. The principle is as follows: sewage passes through the adsorbent in the monitoring section of thick bamboo, and partial pollutant in the sewage is adsorbed by the adsorbent and is obtained purifying, and the water after the purification gets into to collect the incasement, then carries out water quality monitoring through water quality monitoring device, compares monitoring result and the sewage data before purifying again, and then the measuring out adsorbent is to the adsorption affinity of pollutant.

Because the influence of the test temperature on the adsorption force of the adsorbent on the pollutants is large, the temperature needs to be adjusted in order to explore the adsorption force of the adsorbent on the pollutants in different temperature states. Therefore, the pollutant adsorption capacity monitor with adjustable temperature and small temperature difference of each part is designed, and the monitor plays an important role in accurately monitoring the adsorption capacity of the adsorbent to pollutants.

To solve the problem, the patent with the application number of CN201821595687.8 discloses a pollutant adsorption capacity monitor, in the scheme, the rotation shaft, the connection rope, the stirring rod, the spring, the one-way water inlet valve and the heat carrying medium are arranged, the temperature monitoring can be controlled by the heat carrying medium, the rotation shaft, the connection rope, the stirring rod, the spring and the one-way water inlet valve form a whole, the connection rope is driven to wind by the rotation shaft, the heat transfer between the adsorbent and the water body is promoted, the temperature difference between monitoring parts is reduced, and the monitoring accuracy is kept. However, when the scheme is used for stirring the water body, the water body is driven to oscillate by mainly adopting a mode that the stirring rod is vertically upwards and downwards, so that insufficient heat exchange is caused between the water body in the left-right direction and the water body in the up-down direction, and moreover, as the stirring action of the stirring rod on the adsorbent is small in ascending or descending, the adsorbent is poor in mixing and contact with the water body, so that the detection precision of the adsorbent on the adsorption force of water pollutants is reduced.

The motor is started, the motor drives the driving rod to rotate, the driving rod drives the lifting plate and the lifting plate to lift in the rotating process, and the lifting plate lifts and drives the pulley connected with the lifting plate in a rotating mode to lift. Because the length of the pull rope is fixed, when the lifting plate drives the pulley to descend, the pulley pulls the sliding block to slide downwards through the pull rope so as to extrude the spring, and the pulley rotates in the positive direction under the action of the pull rope; when the lifting plate rises, the pulley does not give acting force to the pull rope, the sliding block rises under the restoring force of the spring, the pull rope is pulled in the process that the sliding block rises, the pulling force acts on the pulley, and the pulley rotates reversely.
