Manual material feeding assistor for mixing drum in powdered activated carbon wet type feeding device

Abstract

The invention discloses a manual material feeding assistor for a mixing drum in a powdered activated carbon wet type feeding device. The upper end of the mixing drum is provided with a manual feeding port, the manual feeding port is provided with a funnel, and the funnel not only facilitates the material feeding of working staff, but can also effectively prevent powdered activated carbon from getting out of the mixing drum, thereby improving the surrounding environment of the mixing drum; a channel at the lower end of the funnel is provided with a speed regulating device for controlling material feeding speed, the device can regulate and control the material feeding speed as required so as to uniformly mix the powdered activated carbon with water; a reticular barrier layer is arranged above the speed regulating device and can prevent foreign matters from dropping into the mixing drum accidently, therefore, due to the presence of the reticular barrier layer, the working staff can directly place a bag, which is filled with the powdered activated carbon, in the mixing drum with the opening of the bag facing downwards, and the material feeding speed is controlled by the speed regulating device below and the bag and other possible foreign matters are intercepted by the reticular barrier layer, so the materials can still be fed normally even without onsite monitoring of the working staff.

Description

technical field [0001] The invention relates to a powder activated carbon wet dosing device, in particular to an auxiliary device for feeding and controlling the feeding speed when the mixing cylinder in the powder activated carbon wet dosing device adopts manual feeding. Background technique [0002] The pollution of drinking water sources in my country is becoming more and more serious, and there are many types of organic substances in water sources. In the process of water treatment, activated carbon is usually added to adsorb and remove organic substances and other impurities in raw water. Due to the large specific surface area of ​​powdered activated carbon, it has strong adsorption, which can effectively remove the color and odor of raw water, reduce turbidity, and effectively reduce the pollutant content in raw water. [0003] The dosing method of powdered activated carbon usually adopts the wet dosing method, that is, after mixing the powdered activated carbon with w...

Problems solved by technology

Generally, the artificial feeding opening on the mixing cylinder is a hole opened on the upper end of the mixing cylinder. When the mixing cylinder does not need to add powdered activated carbon, this hole-shaped artificial feeding opening is usually closed with an end cover. When the mixing cylinder needs to When adding powdered activated carbon, workers add powdered activated carbon through this hole-shaped artificial feeding port. Since the artificial feeding port is in the shape of a plane hole, it is easy to sprinkle powdered activated carbon around the mixing cylinder. Moreover, when several mixing cylinders are When in series, it is necessary to mix the powdered activated carbon and water evenly in proportion, so it is necessary to control the speed of adding powdered activated carbon and water so that the powdered activated carbon and water can be mixed evenly. However, since the artificial feeding port is a simple hole shape structure, and there is no feeding auxiliary equipment, it is difficult to control the speed of feeding only by the experience of workers, causing a lot of inconvenience
