Abstract

The utility model discloses a coagulation device comprising a cylinder body provided with a water feeding pipe and a water discharging pipe. The coagulation device is characterized in that upper and lower openings are arranged in the cylinder body; a flow guide cylinder with a through hole is arranged on the side wall of the cylinder body; a rotating shaft with a blade of an agitator stretches into the flow guide cylinder and the water outlet of the water feeding pipe is located at the bottom of the flow guide cylinder; and the outlet of a medicine feeding pipe is located below the blade in the flow guide cylinder and above the outlet of the water feeding pipe. By utilizing the flow guide cylinder, strong convection and turbulent flow are easy to form, so that raw water and a coagulant are rapidly and uniformly mixed; and therefore, the problems in the conventional mechanical agitation that the agitating efficiency is low, the power is large, the dispersion of medicaments is not uniform and a partial medicament concentration is too high, so as to accelerate the coagulant to be bred and hydrolyzed and accelerate the effect with colloid in water.

Description

a coagulation device

technical field

The utility model relates to a coagulation device.

Background technique

Compared with hydraulic mixing facilities, mechanical coagulation mixing has the advantages of high efficiency and can make corresponding adjustments with changes in water quality, volume, coagulation amount and types to achieve the best treatment effect. Normally, the most ideal flow pattern in mechanical stirring is that the liquid circulates from bottom to top along the stirring shaft, and then flows from top to bottom near the wall of the vessel. This circulation mode not only has a strong convection effect, but also provides Certain turbulent diffusion ability. However, the existing axial-flow mechanical agitation can only form three-dimensional and highly unstable convection, resulting in low stirring efficiency of the agitator, high power, uneven distribution of medicament, and excessive concentration of local medicament, which affects the hydrolysis of the coagulant and its Interaction with hydrocolloids.

Purpose of utility model

The purpose of the utility model is to provide a coagulation device with uniform coagulation and stirring effect.

In order to achieve the above purpose, the following technical solution is adopted: a coagulation device, including a cylinder with an inlet pipe and an outlet pipe, characterized in that: the cylinder is provided with upper and lower openings, and a flow guide with through holes on the side wall The rotating shaft with blades of the agitator extends into the guide tube, the outlet of the water inlet pipe is located at the bottom of the guide tube, and the outlet of the dosing tube is located below the blades in the guide tube and above the outlet of the water inlet pipe.

The utility model can easily form strong convection and turbulence through the use of the guide tube, so that the raw water and the coagulant can be mixed quickly and evenly, and effectively solve the problem of low stirring efficiency, high power, uneven dispersion of medicaments, and localized medicaments in conventional mechanical mixing. The problem of high concentration promotes the hydrolysis of the coagulant and its interaction with the colloid in water.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is a schematic diagram of the guide cylinder in Fig. 1 .

In Fig. 1, part 1 is a cylinder body, part 2 is a guide tube, part 3 is an agitator, part 4 is a water inlet pipe, part 5 is a medicine feeding pipe, and part 6 is a water outlet pipe.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1 and Figure 2, the raw water enters the coagulation device through the water inlet pipe 4, and the metered coagulant is added into the upper part of the water inlet pipe through the coagulant dosing pipe 5, and then stirred rapidly by the agitator 3 to make the coagulation The agent and the water flow are quickly and evenly mixed. Under the action of the agitator 3, the water flow flows into the coagulation device through the hole and the top of the guide tube respectively, forming the water flow in the upper and lower circulation convection and local turbulence of the pool body, thereby improving the mixing effect.
