Peat drying and dewatering device capable of adjusting treatment mode according to water content

Abstract

The invention discloses a peat drying and dewatering device capable of adjusting the treatment mode according to the water content. The device comprises a material distributing and detecting mechanism, the material distributing and detecting mechanism comprises a tank body, a vertically-through feeding cavity is formed in the tank body, a pressure sensor is arranged on the inner wall of the feeding cavity, and a valve is arranged in the feeding cavity; according to the peat drying and dewatering device capable of adjusting the treatment mode according to the water content, peat with different water contents can be classified, the classification process is automatic, compared with manual classification, the efficiency is greatly improved, the labor intensity of workers is relieved, and when the peat entering the tank body is in the high water content state, the diversion guide device guides the peat into the extrusion treatment equipment for extrusion treatment, and when the water content of the peat is low, the diversion guide device guides the peat into the hot air drying equipment for treatment, so that unnecessary heat treatment is avoided, the heat treatment time of the high-humidity peat is greatly shortened, the energy consumption is greatly reduced, and the enterprise cost is reduced.

Description

technical field [0001] The invention relates to the technical field of peat drying, in particular to a peat drying and dehydration treatment device. Background technique [0002] Peat contains a lot of water in its natural state, and its solid-phase substances are mainly composed of incompletely decomposed plant residues, fully humified humus and minerals, and the former two organic substances generally account for half of the solid-phase substances above. [0003] According to the formation conditions of peat, the characteristics of the plant community and the nutrient situation, peat can be divided into 3 types. [0004] (1) High peat (oligotrophic peat) [0005] High-level peat is formed on relatively high terrain and is red or brownish yellow in color. It is formed by plants such as sphagnum moss and green moss. It has a relatively short growth period, low ash content, high water holding capacity, poor decay degree, and high acidity. [0006] (2) Low peat (rich nutrie...

AI Technical Summary

Problems solved by technology

[0011] Before peat is used as fuel, peat needs to be dehydrated and dried. Existing peat drying is generally carried out by drum heating. This method cannot adapt to the water content of peat. The peat with water content cannot be removed by physical extrusion, which consumes a lot of heat energy. For low water content, continuous thermal drying in a state that is about to dry causes unnecessary consumption. In view of the above shortcomings, the present invention improves
