Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a flocculant stirring device. Background Art

[0002] Flocculants are usually divided into organic flocculants and inorganic flocculants. Organic flocculants are composed of high molecular polymers, which can condense tiny suspended particles and colloids in water into larger particles through various modes of action such as adsorption, neutralization, and coagulation, thereby achieving the purpose of purifying water sources.

[0003] In practical applications, the full dissolution and dispersion of organic flocculants has always been a difficult problem to effectively solve in the detailed process of sewage treatment. Since such flocculants are mostly high-molecular organic matter, when they dissolve in water, they are often not fully dissolved or dispersed, resulting in a large amount of flocculants being added to the sewage before they are fully dissolved or dispersed, and they fail to play the proper flocculation and sedimentation role. At the same time, it will also have an adverse effect on the subsequent sludge dewatering. At present, the more common flocculant mixing and stirring method is to stir and mix the liquid in a vertical mixing barrel by a motor-driven stirring rod. This simple stirring method usually takes a long time to fully mix the organic flocculant and water, and is inefficient. Especially when treating a large amount of sewage, it often cannot keep up with the supply demand and takes a long time to wait; therefore, a flocculant stirring device is needed to solve the above problems.

When describing the implementation of the present invention, for the sake of convenience, the cross-sectional diagram showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Figure 1-Figure 3 The schematic diagram of the whole structure of a flocculant stirring device of the utility model is shown in FIG. Figure 1-Figure 3 A flocculant stirring device according to the present embodiment includes a support frame 100, a mixing drum 200 is horizontally installed on the inner side of the support frame 100, end shafts 210 are fixed at both ends of the mixing drum 200 to form a rotation connection with the support frame 100 through bearings, a feeding cylinder 230 equipped with an electromagnetic valve is also provided on the outer side of the mixing drum 200, a rotating shaft 300 is rotatably installed at the axis center at both ends of the inner side of the mixing drum 200, a plurality of hollow stirring blades 310 are arranged on the outer side of the rotating shaft 300 along its length direction, a plurality of disturbance plates 220 are arranged on the inner side wall of the mixing drum 200, and a rotating drive component 400 that can drive the mixing drum 200 and the rotating shaft 300 to rotate synchronously and reversely is arranged on the outer side of the support frame 100.

[0022] The hollow stirring blade 310 includes a fixed frame 3101 fixed to the outside of the rotating shaft 300, and a steel mesh 3102 fixed to the inside of the fixed frame 3101. In the present embodiment, by changing the conventional stirring blade into a hollow blade with a larger coverage area, when in use, the hollow stirring blade 310 is driven to rotate by the rotating shaft 300, so that the flocculant mixture flowing radially in the mixing drum 200 is fully broken up, stirred and mixed. Compared with the traditional stirring rod form, the stirring and mixing is more sufficient and thorough, and the mixing efficiency is effectively improved.

[0023] Furthermore, a bottom plate 110 is fixed to the bottom of the support frame 100. The bottom plate 110 provides better structural stability for the stirring device and makes it more stable to use.

[0024] One end of the rotating shaft 300 is passed through the inner side and outer end of the end shaft 210 via a sealing shaft;

[0025] The rotating drive assembly 400 includes a chassis 410 fixed to the outside of the support frame 100, a servo motor 420 installed on the inside of the chassis 410, a main gear 430 installed on the bottom output shaft end of the servo motor 420, a passive bevel gear 1 440 fixed to the outside of the end shaft 210 and meshing with the main gear 430, and a passive bevel gear 2 450 fixed to the outer end of the rotating shaft 300 and meshing with the main gear 430. During operation, the servo motor 420 will drive the active bevel gear 1 440 and the passive bevel gear 2 450 to form synchronous and reverse rotation through the main gear 430, thereby driving the end shaft 210 and the rotating shaft 300 to rotate synchronously and reversely, and then driving the mixing drum 200 and the rotating shaft 300 to rotate synchronously and reversely. The structure is simple and easy to maintain, and the container and the stirring assembly can be rotated simultaneously.

[0026] A water inlet pipe 500 with a port corresponding to the feed barrel 230 is provided on the top of the support frame 100, and a material hopper 510 with a discharge port corresponding to the feed barrel 230 is also provided on the top of the support frame 100. When in use, when the mixing drum 200 drives the feed barrel 230 to rotate upward, the electromagnetic butterfly valve on the inside of the feed barrel 230 is opened, and clean water is injected into the feed barrel 230 and the mixing drum 200 through the water inlet pipe 500. At the same time, the flocculant powder can be introduced into the mixing drum 200 through the material hopper 510. In this way, when the ratio of clean water and flocculant powder is completed, the valve of the feed barrel 230 can be closed to carry out subsequent mixing and stirring, which is simple and easy to use. Of course, it can be understood that the water inlet pipe 500 and the material hopper 510 can be electrically controlled, which will be more convenient in use.

[0027] Furthermore, a drain valve 2301 is provided on one side of the feed cylinder 230. In order to facilitate the discharge of the mixed flocculant liquid, when the mixing drum 200 drives the feed cylinder 230 to rotate downward, the drain valve 2301 can be opened immediately, so that the liquid in the mixing drum 200 can be discharged to the sewage treatment unit through the feed cylinder 230.

[0028] In summary, a flocculant stirring device of the present embodiment, when in use, when the mixing drum 200 drives the feed drum 230 to rotate upward, the electromagnetic butterfly valve on the inner side of the feed drum 230 is opened, and clean water is injected into the feed drum 230 and the mixing drum 200 through the water inlet pipe 500, and the flocculant powder can be introduced into the mixing drum 200 through the material hopper 510. During stirring, the mixing drum 200 and the rotating shaft 300 are driven by the rotating drive component 400 to form synchronous reverse rotation. During this process, the rotating mixing drum 200 can continuously bottom-flip and stir the liquid in the drum through the disturbance plate 220, so that the liquids are fully blended. At the same time, the rotating hollow stirring blades 310 can fully break up and stir the reverse-flowing liquid, and cooperate with each other to fully dissolve and disperse the flocculant and water. Compared with the traditional stirring method, the device is more thorough in stirring and mixing.

[0029] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
