Alum Crushing and Spreading Integrated Equipment for Domestic Wastewater Treatment

Abstract

The invention discloses alum crushing and sprinkling integrated equipment for domestic wastewater treatment. The structure of the equipment consists of a crushing and sprinkling apparatus, hydraulic pumps, telescopic oil cylinders, electric lifting bars, walking casters, a splash guard, and a controller. The telescopic oil cylinders are arranged on the two sides of the crushing and sprinkling apparatus. One end of each telescopic oil cylinder is fixed to the outer wall of the crushing and sprinkling apparatus. Each hydraulic pump is arranged on the corresponding telescopic oil cylinder and cooperates with the corresponding provided with. The telescopic oil cylinders are arranged on the two sides of the crushing and sprinkling apparatus, and so the length of the telescopic oil cylinders canbe adjusted according to the size of a sedimentation tank, which facilitates the material sprinkling. The crushing and sprinkling apparatus can be raised by using the electric lifting bars, thereby increasing the material sprinkling area. The crushing and sprinkling apparatus can rapidly carried out primary and secondary crushing on alum, and so the alum can be powdered and sprinkled into the sedimentation tank, thereby improving the sedimentation speed of domestic wastewater in the sedimentation tank.

Description

technical field [0001] The invention relates to the field of crushing and spreading equipment, in particular to an integrated equipment for crushing and spreading alum for domestic wastewater treatment. Background technique [0002] Domestic wastewater refers to the washing water excreted by residents in their daily life. In fact, only a small part of the wastewater is treated, and most of it is directly discharged into rivers without treatment. Smaller cities are more serious. Feces, etc. are generally not discharged directly, but have collection measures. The components of pollutants in wastewater are extremely complex and diverse, and it is difficult to achieve the purpose of complete purification by any treatment method, and it often takes several methods to form a treatment system to meet the treatment requirements. According to the degree of treatment, the wastewater treatment system can be divided into primary treatment, secondary treatment and advanced treatment. ...

AI Technical Summary

Problems solved by technology

[0003] When the domestic wastewater in the sedimentation tank is treated, alum will be used, and the alum needs to be crushed. After the crushing is completed, it will be manually sprinkled into the sedimentation tank to settle the domestic wastewater in the sedimentation tank. A lot of time and energy and low work efficiency, the operator is prone to dizziness and fatigue if he stays around the sedimentation tank for a long time
