Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment agent spreading device for sewage treatment. Background Art

[0002] Sewage refers to water containing various wastewater and pollutants generated during human production, life and social activities. Sewage contains various pollutants such as organic matter, inorganic matter, microorganisms and heavy metals, which are harmful to the environment and human health. Therefore, sewage treatment agents are needed to effectively treat sewage. Sewage treatment agents are chemical substances used in the sewage treatment process. Their function is to help remove pollutants, odors and color in sewage, as well as to improve treatment efficiency. In daily life, people often need to spread solid sewage treatment agents into sewage. The molecular structure of solid sewage treatment agents can absorb suspended particles and colloids in sewage, causing them to quickly aggregate to form larger clusters, thus achieving solid-liquid separation.

[0003] Existing sewage treatment agents are usually spread into sewage treatment pools through spreaders. However, for larger particles of sewage treatment agents, the dissolution rate in sewage is relatively slow, and it takes a long time to fully dissolve and play a role, thus affecting the treatment effect. At the same time, when the sewage treatment agent is spread through the filter screen, the continuous accumulation of the treatment agent may cause the screen to be blocked by the treatment agent, reducing the permeability of the screen, thereby affecting the spreading efficiency of the treatment agent, resulting in uneven spreading. In addition, the existing spreader is very likely to repeat the spreading in multiple areas when moving while spreading, resulting in low uniformity of the treatment agent. Summary of the invention

[0040] The working principle of this embodiment is as follows: a solid sewage treatment agent is placed in the treatment agent placement box 22. When work is required, the control valve 23 is opened and poured into the movable inner shell 21 through the feed trough 24. At this time, the second motor 30 drives the driving spindle 31 to rotate, and the driving spindle 31 drives multiple central fixed disks 27 on the shaft to rotate. The central fixed disk 27 drives the crushing hammer 28 to rotate along the driving spindle 31, so that the crushing hammer 28 rotates around the connecting shaft 29, so that the crushing hammer 28 and the impact plate in the movable inner shell 21 cooperate to crush the solid sewage treatment agent. At the same time, during the rotation of the driving spindle 31, the driving spindle 3 1 drives the first connection disk 32 to rotate, and the movable inner shell 21 is pushed by the return spring 36 so that the second connection disk 34 and the driving main shaft 31 are always in a state of being in contact. Under the mutual collision of the first fixed protrusion 33 and the second fixed protrusion 35, the movable inner shell 21 vibrates along the axial direction of the driving main shaft 31, so that the crushed sewage treatment agent is discharged through the filter screen 26. At the same time, the larger particles of sewage treatment agent continue to be crushed in the movable inner shell 21 until they can be discharged from the filter screen 26. The continuous axial shaking can also prevent the sewage treatment agent from clogging the filter screen 26 and affecting the subsequent spreading process;

[0041] The crushed powdered sewage treatment agent is collected by the collecting hopper 50 and falls into the main collecting pipe 55.

[0042] After the spreading mechanism 5 moves and spreads for a period of time, the fourth motor 67 is started, and the output end of the fourth motor 67 drives the active turntable 60, so that the active turntable 60 drives the arc groove 61 to rotate clockwise, and the arc groove 61 can drive the engaging connection block 65 to slide in the groove, so that the engaging connection block 65 drives the blocking sliding plate 66 at one end of the connecting rod 64 to slide inward, and the blocking sliding plate 66 slides inward so that the multiple blocking sliding plates 66 form a complete ring, thereby blocking the multiple discharge holes 58. The discharge hole 58 stops spreading the sewage treatment agent in the sewage treatment tank 1. After the spreading mechanism 5 moves for a period of time, the fourth motor 67 drives the active turntable 60 to rotate counterclockwise, so that the engaging connection block 65 slides outward in the arc groove 61. The engaging connection block 65 drives the blocking sliding plate 66 at the other end to slide outward through the connecting rod 64, thereby releasing the blockage of the blocking sliding plate 66 to the discharge hole 58, so that the spreading mechanism 5 can spread the sewage treatment agent normally again.
