Problems solved by technology

Under the existing technical conditions, the dilution and mixing of polyacrylamide is manually timed and quantitatively added, which can easily cause too little dosage to affect the required concentration, or too much dosage will cause insoluble and waste
Moreover, polyacrylamide is prone to compaction due to moisture, which further increases the difficulty of manual dosing, and cannot control the concentration of polyacrylamide in the flocculant to remain unchanged

Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0030] Such as Figure 1-5 As shown, a quantitative feeding device for preventing the caking of powdery particles includes a storage tank 1 and an anti-caking device 2, and the anti-caking device 2 is installed in the storage tank 1. The storage tank 1 is a cylinder with a partition 11 at the bottom. The partition 11 divides the inner cavity of the storage tank 1 into two chambers. The top of the partition 11 is the feeding chamber, and the bottom of the partition 11 is the crushing chamber. ; The central part of the partition 11 is provided with a stirring shaft through hole. The anti-caking crushing device 2 comprises a stirring shaft 21 and a stirring blade 22, the stirri...

Abstract

The invention discloses a quantitative feeding device for preventing the caking of powdery granular matter. The device is suitable for quantitative feeding of powdery granular matter that is easy to compact or the feeding environment is humid, can effectively prevent the compaction of powdery granular matter, and can ensure quantitative feeding of powdery granular matter ; The feeding device includes a storage tank and an anti-caking device; the powdery particles are ground twice to become fine particles, and then quantitatively added to the target container through the quantitative feeding device.

Description

technical field [0001] The invention relates to a feeding device, in particular to a quantitative feeding device for preventing the caking of powdery particles. Background technique [0002] Existing sewage treatment technologies mainly meet the discharge standards through physical and chemical treatment and biochemical treatment. The main purpose of the physical and chemical treatment process is to fully flocculate and settle the sewage. Usually, the sewage is first introduced into the pool and the pH is adjusted to alkaline with lime. Then add ferrous sulfate to carry out flocculation and sedimentation treatment of sewage. Under normal circumstances, the flocculation can be fully achieved by adjusting the pH to 9-11, and the supernatant can be separated after standing in the sedimentation tank for further biochemical treatment. In order to enhance the flocculation effect and increase the sedimentation efficiency, a flocculant is further added to the sewage. The operating...
