Description

Technical Field

[0001] The utility model relates to the technical field of flocculant production, and more specifically, to a stirring device for producing sewage flocculants. Background Technique

[0002] Flocculation refers to the phenomenon or operation in which suspended particles in water or liquid aggregate and become larger, or form flocs, so as to accelerate the sedimentation of particles and achieve the purpose of solid-liquid separation. Usually, flocculation is carried out by adding appropriate flocculants, whose function is to adsorb particles and "bridge" between particles, thus promoting aggregation. In the process of purifying sewage, the use of flocculants plays a key role. Flocculants are usually electrolytes such as ammonium salts or colloidal chemicals with adsorption effects.

[0003] To produce flocculants, first, the flocculant raw material powder needs to be fully mixed with water. The existing flocculant production devices generally adopt the mixing method of a mixer. The device structure is simple, saving manpower and material resources, and to a certain extent, improving the raw material utilization rate.

[0004] Although the device has many beneficial effects, there are still the following problems: ordinary mixers are prone to insufficient mixing of raw materials, impurities and agglomerated particles exist in the flocculant, and during the long-term use of the device, raw materials will accumulate on the mixing blades or the barrel wall and need to be cleaned regularly. In view of this, we propose a stirring device for producing sewage flocculants. Content of the Utility Model

[0031] The device or equipment models involved in this article are as follows:

[0032] Motor 315: HLB3640.

[0033] Working principle: When the device is required to stir the flocculant production, first introduce water into the stirring barrel 1 through the water inlet 110, and then put the raw material powder into the device through the funnel 540. The motor 315 drives the main rotating shaft 311 and the main gear 410 to rotate, so that the first stirring blade 312 and the second stirring blade 322 start the stirring work. The main gear 410 drives the engaged secondary gear 420 to rotate, and the secondary gear 420 drives the secondary rotating shaft 321 to rotate, so that the third stirring blade 322 stirs. Convection is generated through the different rotation speeds, sizes and heights of the three stirring blades to stir the raw materials more fully. When there are impurities or agglomerated particles, the filter screen assembly 2 blocks them on the top layer of the stirring barrel 1 to prevent impurities and agglomerated raw materials from appearing in the product. After the stirring is completed, open the valve 130 to transfer the flocculant to other processes. When cleaning and replacement are required, through the keyway fit of the barrel cover positioning groove 140 and the barrel cover boss 510, slightly twist the barrel cover 5 to remove the stirring assembly 3 and the filter screen assembly 2. The filter screen assembly 2 can also be disassembled and cleaned through the keyway fit of the filter screen positioning groove 213 and the filter screen boss 221.
