Description

Sludge medicament mixer

Technical Field

The invention relates to the technical field of environment-friendly equipment, in particular to the technical field of sludge treatment equipment, and specifically relates to a sludge medicament mixer.

Background

The sludge drying is to remove most of the moisture contained in the sludge so as to achieve the aim of recycling. The method mainly comprises the processes of physical filtration, extrusion, heating evaporation or drying, and finally, the water content of the sludge is controlled to be 10% -40% according to the requirement, and the sludge is recycled as nutrient soil, so that the aim of changing waste into valuables is fulfilled.

Although the principle of the existing sludge drying technology is approximately the same, the actual treatment process and the equipment layout are greatly different. Sludge with a high water content is generally conveyed by a sludge pump, and sludge with a low water content is generally conveyed by a screw conveyor. However, during the conveying process, the sludge is easy to expand due to a large amount of organic matters contained in the sludge, so that the sludge is blocked in a conveying pipeline, and even the pipe explosion phenomenon occurs, so that the sludge drying treatment process is interrupted.

Disclosure of Invention

To solve this technical problem, the applicant's technical team has developed agents with inhibitory or even eliminating action on sludge bulking to act as an anti-bulking action when added to the sludge. However, due to the solid property of the sludge and the great difference between the medicament and the sludge to be treated, the medicament and the sludge cannot be fully mixed, so that the medicament cannot achieve the ideal anti-swelling effect. Therefore, if the medicament and the sludge can be fully mixed, a new technical problem is solved, and in order to solve the technical problem, the applicant researches and invents a sludge medicament mixer capable of realizing three-dimensional stirring and mixing, which can fully mix the sludge to be dried with any water content and the medicament, so that the medicament can be uniformly distributed in the sludge, and the optimal anti-swelling technical effect is achieved.

a sludge medicament mixer comprises an outer shell, wherein a feeding pipe is arranged at the upper part of the outer shell, a discharging hopper is arranged at the lower part of the outer shell, a stirring mechanism is horizontally arranged in the outer shell, and the stirring mechanism is driven by a first driver arranged on the outer shell; the stirring mechanism comprises a plurality of spiral stirrers which revolve and rotate relative to the central shaft of the stirring mechanism, and the following conditions are also met between any two adjacent spiral stirrers: the radian is equal, the rotation direction is the same, and the spiral blade direction is opposite. The anti-swelling agent and the sludge to be treated enter the mixer through the feeding pipe, and when the discharge hopper is in a non-discharge state, the agent and the sludge can be repeatedly stirred and mixed only in the space enclosed by the outer shell by the stirring mechanism. The stirring mechanism is driven by the first driver to be in a multi-dimensional rotating state, and the stirring mechanism rotates integrally, namely, the revolution can enable sludge in the mixer to turn up and down along with the rotation of the stirring mechanism; the rotation of helical agitator can be located the mud around the helical agitator in the revolution and realize horizontal position and remove, and the helical blade opposite direction of two adjacent helical agitator in addition, the horizontal dislocation still can take place for mud when vertical rotation is turned over so, realizes the end of crossing violently and vertically, because horizontal rotation and vertical rotation are gone on simultaneously, so the three-dimensional disorder degree of increase mud that can be very big. Moreover, because there is the space clearance between two adjacent spiral agitator, at the in-process of stirring, mud still can take place the further chaotic degree that strengthens that drops naturally under the action of gravity, realizes the improvement of stirring efficiency.

In order to realize that the first driver realizes the revolution and the rotation of the stirring mechanism simultaneously, preferably, the stirring mechanism further comprises a gear box, wherein the input end of the gear box is in driving connection with the first driver, any output end of the gear box is in driving connection with one end head of the stirrer, the other end head of any stirrer is in rotating connection with a first mounting plate, and the first mounting plate is in rotating connection with the outer shell.
