Problems solved by technology

[0004] 1. When the sludge is dried, due to the different accumulation heights of the sludge, the drying efficiency of the sludge is slow, and there will be a phenomenon that the sludge cannot be dried inside, resulting in low drying efficiency and poor effect of the sludge. , the sludge at the outer end of the conveyor belt cannot be dried;
[0005] 2. After drying, the sludge will not be able to move into the extrusion crusher, so manual assistance is required when the sludge is crushed

Embodiment Construction

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in combination with specific diagrams. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0032] Such as Figure 1 to Figure 6As shown, an integrated system for sludge reuse, drying and pulverization includes a bottom plate 1, a conveyor belt 2, a flattening mechanism 3, a dryer 4, a twin-roll extruder 5, and a pressing mechanism 6. The bottom plate 1 A conveyor belt 2 is distributed above the conveyor belt 2, and sludge is piled on the conveyor belt 2, and the sludge can be transported through the conveyor belt 2. A leveling mechanism 3 and a dryer 4 are distributed on the top of the conveyor belt 2 from left to right. The outer ends of the flat mechanism 3 and the dry...

Abstract

The invention relates to a sludge recycling, drying and crushing integrated system that comprises: a bottom plate, a conveying belt, a flattening mechanism, a drying machine, a double-roller extrudingmachine and a pressing mechanism, wherein the conveying belt is distributed above the bottom plate; the flattening mechanism and the drying machine are sequentially distributed above the conveying belt from left to right, the outer end of the flattening mechanism and the outer end of the drying machine are both installed on the top of the bottom plate, the double-roller extruding machine is distributed below the right side of the conveying belt and is installed on the top of the right end of the bottom plate, and the pressing mechanism is installed on the outer side face of the double-rollerextruding machine. The invention solves the following problems that when existing sludge is crushed, the sludge drying efficiency is low due to the fact that the stacking heights of the sludge are different when the sludge is dried, the phenomenon that the interior of the sludge cannot be dried occurs, the sludge drying efficiency is low, the effect is poor, and the sludge at the outer end of a conveying belt cannot be dried.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to an integrated system for sludge reuse, drying and pulverization. Background technique [0002] A lot of sludge is often produced in sewage treatment projects. Sludge is a potential high-quality "secondary resource" with high moisture content, high calorific value, and rich organic matter and nutrients. The sludge contains a large amount of organic matter, nitrogen, phosphorus and other nutrients needed by plants. Mud can also be used as a building material. [0003] Before the sludge is recovered and crushed, the sludge needs to be dried, and then the dried sludge is crushed. The existing sludge is mostly dried using a conveyor belt to transfer it to the dryer. The sludge is dried, and the dried sludge is pulverized by an extrusion pulverizer. The problems existing in the pulverization of the existing sludge are as follows: [0004] 1. When the sludge is dried...
