Settling device with automatic sludge discharge function

Abstract

The invention provides a settling device with an automatic sludge discharge function. The settling device comprises a settling pond, a sludge storage tank, a sludge discharge head, a siphon sludge discharge pipe, a flowmeter, a water inlet system and a water outlet system. According to the settling device, the siphon sludge discharge pipe is arranged in the sludge storage tank, and water outlet is closed when sludge needs to be discharged at the moment a turbidimeter reaches a preset value, so that the water level of the settling pond exceeds the maximum level point of the siphon sludge discharge pipe; therefore, siphon sludge discharge is realized. Water inlet is closed, so that the water level of the settling pond is flush with the horizontal line of a sludge discharge hole of the siphon sludge discharge pipe; therefore, sludge discharge is stopped, then water inlet and water outlet are started, and the normal working state of a system is recovered. Therefore, the settling device provided by the invention has the automatic sludge discharge function, the sludge can be discharged in time according to the requirement of sedimentation treatment, the design requirement for the sludge storage tank does not need to be relatively high, and no power equipment is required for assisting sludge discharge; in addition, the settling device is simple in structure, high in efficiency, low in cost and strong in generalization.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a settling device with automatic mud discharge function. Background technique [0002] In the existing water treatment field, sedimentation process is generally used to remove solid matter in water, and the sludge formed after sedimentation needs to be discharged by corresponding treatment equipment such as mud hopper for further treatment and disposal. The processing equipment in the prior art, such as mud hoppers, generally rely on gravity sedimentation for sludge discharge or external power equipment to assist in sludge discharge. Gravity sedimentation for sludge discharge is often passive on the one hand, and cannot discharge sludge in time to meet the needs of sedimentation treatment, resulting in sludge waste. Accumulation, which in turn affects the effluent water quality of sedimentation treatment. On the other hand, the design requirements for the mud bucket are relatively ...

AI Technical Summary

Problems solved by technology

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a settling device with an automatic mud discharge function, which is used to solve the problems in the prior art that the mud discharge does not affect the quality of the effluent water and the mud The problem of high bucket design requirements, the use of external power equipment to assist in sludge discharge has the problems of complex equipment construction and high sludge discharge costs
