Embodiment 1

[0023] Embodiment one: power mechanism 9 comprises casing 91, second motor 92, running wheel 93, second gear 94, the 3rd gear 95, second gear 96 and second gear 97, and the right side of casing 91 is equipped with second Motor 92, and the drive shaft of the second motor 92 extends to the inside of the casing 91 and is welded with a runner 93, and the left end of the central axis of the runner 93 is connected with the inner wall of the casing 91 by an embedded bearing, and the top of the runner 93 is provided with a second Gear 94, the third gear 95 is arranged below the running wheel 93, and the second gear 96 is meshed above the second gear 94. The two ends of the running wheel 93, the second gear 94 and the third gear 95 all pass through the inner wall of the casing 91 The inner bearing is connected, the central shaft of the second gear 96 is connected with the central shaft of the third gear 95 through a belt and a pulley, and the left end of the central shaft of the third g...

Embodiment 2

[0024] Embodiment 2: The first motor 4 starts to drive the first gear 5 to rotate, and the first gear 6 drives the feed opening 2 to rotate, so that the outer cylinder 1 and the inner cylinder 7 are rotated, and the alum in the storage cylinder 3 passes through the outlet When the feed port 8 is spilled, the alum rotates through the discharge port 8 to generate centrifugal force, which further improves the range of delivery of the device, and cooperates with the front and rear offset of the discharge port 8 to control the water area in a circular area below the device. Blind spots are placed evenly, with strong practicability.

Abstract

The invention discloses an alum feeding device for a sewage treatment tank. The device comprises an outer barrel and a first motor, a material passing opening is formed in the top end of the outer barrel, the top end of the material passing opening is sleeved with a storage barrel, a first motor is installed on the right side of the storage barrel, a first gear is welded to the bottom end of the driving shaft of the first motor, an inner barrel is arranged in the outer barrel, the bottom end of the inner barrel extends out of the outer barrel to be provided with a discharging port, the left side of the inner barrel is hinged to the inner wall of the outer barrel, and a power mechanism is welded to the right side of the outer barrel. The alum feeding device is large in throwing range, blind-area-free uniform throwing is conducted on a water area in a circular area below the device in cooperation with front-back deviation of the discharging port, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an alum feeding device for a sewage treatment pool. Background technique [0002] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage include pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollution. Sewage treatment: the process of purifying sewage to meet the water quality requirements for drainage or reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, Various fields such as catering are also increasingly entering the daily life of ordinary people. [0003] For example, the application number: 201711087230.6, the patent discloses a sewage treatment pool alum throwing equipme...
