Description

Technical Field

[0001] The utility model relates to the technical field of flocculant preparation, in particular to a raw material mixing device for producing flocculants. Background Art

[0002] In the field of sewage treatment, coagulants are used as a means to strengthen solid-liquid separation. They can be used to strengthen the primary sedimentation of sewage, flotation treatment, and secondary sedimentation after the activated sludge process. They can also be used for tertiary treatment or deep treatment of sewage. When used for conditioning of excess sludge before dehydration, flocculants and coagulants become sludge conditioners or dehydrating agents.

[0003] In the related technology, a Chinese patent document with application number CN202123224988.4 proposes a high-efficiency mixing device for the production of aluminum-iron composite flocculants. The second motor is started, and the second motor drives the rotating block to rotate. The rotating block drives the roller to rotate around the axis with the rotating block as the center through the connecting rod. At the same time, the roller itself is rotatably connected to the connecting rod, thereby driving the swing rod on the outer wall to swing in a circle, and at the same time driving the swing plate inside the mixing barrel to swing up and down, so that the raw materials at the bottom of the mixing barrel are in an active state, and the mixing and stirring are carried out in cooperation with the stirring rod to avoid the raw materials from settling at the bottom, resulting in uneven mixing of the raw materials, thereby improving the mixing effect and efficiency.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the device makes the raw materials at the bottom of the mixing drum active by swinging the swing plate up and down, and although the raw materials at the bottom of the mixing drum can be turned over to a certain extent when the swing plate swings up and down, the specifications of the swing plate are high. If the swing plate is set to a longer width, the raw materials located in the middle part below the swing plate will not float out from both sides due to the width of the swing plate itself, so that the raw materials in the middle part below the swing plate cannot be fully stirred. If the swing plate is set to a shorter width, the raw materials on both sides are less affected by the up and down amplitude of the swing plate, and the raw materials are easy to sink to the bottom. In addition, a sealing sleeve is provided at the intersection of the swing rod and the mixing drum. Long-term use may easily cause the sealing sleeve at the intersection to leak, which is inconvenient to use. In view of this, a raw material mixing device for producing flocculants is proposed to solve the above problems. Utility Model Content
