Abstract

The invention discloses an automatic dosing device for sewage treatment, which consists of a medicine dissolving box, a medicinal powder dosing device, a medicine dissolving mixer, a mixer driving motor, a water inlet pipe, a medicine outlet pipe and a dosing pump. A pre-infiltrating device is arranged between the medicinal powder dosing device and the medicine dissolving box; the medicine dissolving box are separated by two overflow weirs to form a dissolving tank, a curing tank and a storing tank which are adjacent in turn; and a homogenizing stirrer is arranged in the curing tank. The pre-infiltrating device is arranged in the automatic dosing device for sewage treatment and is used for soaking dry flocculant powder, medicine solution flows into the dissolving tank by means of gravity and is stirred and mixed, the curing tank and the storing tank are arranged, low-speed stirring is carried out in the curing tank, and medicine solution meets the requirements of homogenization, curing and activity; the medicine solution passes through the overflow weirs to flow into the solution storing tank, so that the dissolving and stirring of the dry powder, the homogenization and curing of the solution and the dosing of the liquid medicine are synchronously carried out, and the efficiency and the liquid medicine utilization rate are improved; and the dry powder is accurately weighed, the caking of the dry powder is avoided, the concentration of the liquid medicine is ensured, and the medicine solution can be diluted on line according to requirement of actual application concentration.

Description

Technical field: [0001] The invention relates to special equipment for sewage treatment, in particular to an automatic dosing device for sewage treatment which adds flocculant to sewage before a dewatering machine. Background technique: [0002] In the sludge dehydration process of the sewage plant, before the sludge from the sludge storage tank or sludge well enters the dehydrator, PMA flocculant should be added to the sludge for flocculation and mixing reaction, so that the sludge to be dewatered can be flocculated and agglomerated so that Free water is separated. The dissolution, aging and dosage of flocculants are the key to ensure the normal operation of the sludge dewatering machine. At present, there are various types of dosing devices produced in China, most of which are semi-automatic structures, with low efficiency and simple structure. The ratio and concentration of the liquid medicine is inaccurate, the online dilution system is simple, and the dry powder needs ...
