Description
Technical Field
The utility model belongs to the technical field of sewage treatment, concretely relates to integration PAM automatic reagent feeding device convenient to clearance.
Background
Polyacrylamide PAM is a high molecular polymer, has a long molecular chain, can swell first when dissolved, then slowly dissolves, if the amount of polyacrylamide added into water at one time is large, and the polyacrylamide cannot be slowly added in an evenly dispersed manner, the polyacrylamide contacting with water first begins to swell, then the surface area is increased, and further the part not contacting with water is wrapped, so that polyacrylamide aggregates which are not easy to dissolve are formed.
The polyacrylamide molecule has positive groups (-CONH2), can adsorb suspended particles decomposed in a solution and bridge, has strong flocculation effect, and is widely used in the fields of water treatment, metallurgy, papermaking, petroleum, chemical industry, textile, mineral separation and the like. Polyacrylamide PAM is an organic high molecular compound which can be divided into anionic polyacrylamide, cationic polyacrylamide and nonionic polyacrylamide, is white powder or particles, is soluble in water, but has a slow dissolving speed; anionic polyacrylamide is generally used as a wastewater treatment flocculant, and cationic polyacrylamide is generally used for sludge dewatering.
The problems of the current PAM automatic medicine adding device are mainly as follows:
PAM has a slow dissolving speed and a high viscosity, and PAM cannot be dissolved to form a dough when the PAM is not dissolved in time due to too fast or uneven dosing during dissolving and too large dosage during dry powder adding and preparing. Too fast a dosing rate results in a gummy residue. Directly pouring into a barrel, adding water to melt, and forming plastic block-shaped agglomerates. It is difficult to dissolve the agglomerates again regardless of how long they are stirred.
PAM dissolves inhomogeneously or not enough on the one hand can influence the result of use, and these agglomerates can deposit in the dosing tank bottom owing to the action of gravity in addition, block up the pipeline, and then lead to dosing pump to break down, influence equipment and use.
The conventional cleaning method for the PAM agglomerate comprises the following steps:
1. and (4) manually cleaning, and hooking the PAM agglomerates by a worker with a hook. However, the cleaning method has low working efficiency and high agglomerate viscosity, and only scattered parts can be used and cannot be completely cleaned.
2. The equipment is stopped periodically, and workers enter the equipment to remove the agglomerates. However, the cleaning method has large workload, and the normal operation of the equipment is influenced by the equipment stop, so that the working efficiency is influenced.
Therefore, a new integrated PAM automatic dosing device convenient to clean needs to be designed.
