Auxiliary feeding device for high-rod plate-and-frame filter press and use method of auxiliary feeding device

Abstract

The invention discloses an auxiliary feeding device for a high-rod plate-and-frame filter press and a using method of the auxiliary feeding device. The auxiliary feeding device comprises a mixing tank, a heating assembly, a motor and a fixing box; the heating assembly is arranged in the mixing tank in an extending mode, the motor is fixedly connected to the exterior of the mixing tank, and the output end of the motor extends into the mixing tank; and the center of the bottom of the inner wall of the mixing tank is fixedly connected with the fixing box. The auxiliary feeding device has the beneficial effects that the auxiliary feeding device is compact in structure, easy and convenient to operate and high in practicability, sludge in a sludge tank is guided into the mixing tank in batches to be mixed with an agent, the mixing effect can be improved, the sludge guiding dosage can be controlled, then a corresponding agent is put in, agent failure caused by too long mixing time of the sludge and the agent can be avoided, and unnecessary waste is avoided; and the mixing speed of the agent and the sludge can be increased through the heating assembly, colloid chains in the sludge can be separated, and the sludge filter pressing effect is improved.

Description

technical field [0001] The invention belongs to the technical field of feeding devices, in particular to an auxiliary feeding device for a high-rod plate-and-frame filter press and a method for using the same. Background technique [0002] The sludge dehydration treatment board is usually dried by a frame filter press, but before the filter press, it needs to be conditioned according to the characteristics of different sludge sludge. Sludge deep dehydration refers to conditioning the sludge, destroying the cell wall, releasing bound water, Adsorb water and intracellular water to improve the dewatering performance of sludge. Before using the filter press to dehydrate the sludge, we usually condition the dehydrated sludge by coagulation or flocculation. This method can make the sludge The moisture in the mud particles becomes free water to the greatest extent, so that the sludge can get twice the result with half the effort during mechanical dehydration, thereby enhancing the ...

Problems solved by technology

[0003] However, when mixing sludge and drugs, it is usually carried out in a sludge tank. Although this method is simple and convenient, the mixing effect of drugs and sludge is not good, and the sludge cannot be heated in the sludge tank. , it is impossible to improve the colloidal chain in the sludge, and the amount of sludge in the sludge tank is relatively large. When mixing with drugs, it is necessary to add more doses of drugs, and the drug effect time of some drugs is short. The plate and frame filter press cannot filter the sludge in the sludge tank at one time, resulting in drug failure
