Description

Technical Field

[0001] The utility model belongs to the technical field of sludge treatment, and specifically relates to a sludge continuous dynamic precision conditioning device. Background Art

[0002] In the sludge treatment process, it is generally necessary to chemically condition the sludge first, that is, before the filter press dehydration, inorganic compound iron salt or aluminum salt and organic polymer materials are added to the concentrated sludge. The purpose is to make the highly dispersed solid suspended matter in the sewage flocculent, so as to facilitate filtration and extrusion dehydration, and thus meet the requirements of sludge weight reduction, volume reduction and transportation.

[0003] The existing sludge conditioning equipment generally uses two vertical conditioning tanks A and B with agitators for intermittent operation, and the two tanks are used alternately (one tank temporarily stores the conditioned sludge to be pressed; while the other tank is in the process of sludge conditioning). That is: first fill tank A with sludge, then add conditioning agents (commonly known as dosing) such as iron salt or aluminum salt (commonly used PAC) and organic polymer materials (commonly used PAM) while stirring and adding, until "alum flowers" in a flocculated state appear on the surface of the sludge, then stop stirring and set aside. Then fill tank B with sludge, repeat the action of tank A, and perform conditioning operations alternately, reciprocatingly, and intermittently. Among them, polyaluminum chloride (PAC) is an inorganic substance, referred to as polyaluminum, and is an inorganic polymer coagulant, which is often used in sewage treatment to coagulate with inorganic substances to form fine flocs. Polyacrylamide (PAM) is an organic linear polymer with a chemical formula of (C3H5NO)n. It is a hard glassy solid at room temperature and is often used as a flocculant in sewage treatment to gradually enlarge small flocs.

[0004] The existing conditioning equipment has the following problems: First, it is difficult to automatically control the alternating use of the two vertical conditioning tanks A and B, which occupies a large area and is expensive. Second, the reaction speeds of the two commonly used conditioning agents are different, and it is difficult to achieve the ideal conditioning effect under the same stirring intensity of the same stirring tank. Third, the solid content in the sludge is variable, and the amount of conditioning agent should be matched with the amount of solid phase. The existing equipment does not have the detection of the sludge solid content, which inevitably leads to the abuse of conditioning agents and waste. If the conditioning agent is used excessively, it will also cause environmental pollution. Fourth, the volume of the vertical conditioning tank is fixed, while the water filtration performance of the conditioned sludge is variable, that is, some filter water quickly and some filter water slowly. If it is sludge with fast water filtration, you can add more when adding the plate and frame filter press chamber, but at this time, the material in the fixed volume vertical conditioning tank is not enough (commonly known as "not enough"), resulting in a waste of processing capacity.

[0041] In some embodiments, the first stirring assembly 6 and the second stirring assembly 10 both include a drive shaft 13 and a stirring blade 14 spirally wound on the drive shaft 13.

In some embodiments, the discharge port of the first stirring tank 5 is located above the feed port of the second stirring tank 9. The above structure is conducive to the sludge entering the second stirring tank 9 from the first stirring tank 5 under the action of gravity, that is, the material can flow from the high-position first stirring tank 5 into the low-position second stirring tank 9 by gravity, which plays a role in reducing energy consumption. It can be understood that the discharge port of the first stirring tank 5 is located above the feed port of the second stirring tank 9. This can be achieved by a variety of means, such as raising the position of the first stirring tank 5 by a bracket, or digging a groove on the ground and placing the second stirring tank 9 in the groove. The specific means of achieving this are not specifically limited by the present invention.
