Vertical drying-and-granulating integrated equipment and working method thereof

Abstract

The invention relates to vertical drying-and-granulating integrated equipment and a working method thereof. The vertical drying-and-granulating integrated equipment comprises a vertical tank body anda cutter shaft assembly arranged in the vertical tank body, wherein interrupted spiral strip-shaped blades are distributed on the cutter shaft assembly, a cutting edge is arranged on the lower end edge of each blade, and each blade is connected to the cutter shaft assembly through a connecting rod. The equipment provided by the invention conducts circulated and repeated operations until sludge isdispersed into small-diameter particles and then gradually dries the sludge, so drying and granulating of the sludge are efficiently completed in one piece of equipment, and high efficiency is realized.

Description

Technical field: [0001] The invention relates to equipment for drying treatment of sludge or flocculated sludge, in particular to a vertical drying and granulation integrated equipment and a working method thereof. Background technique: [0002] With the increase of urban population, the amount of urban sewage and sludge that needs to be treated is increasing, and there are also various sludge drying and sludge drying equipment. [0003] For example, a vertical pressurized sludge drying treatment device proposed in patent application number 201810125063.8, which includes a housing, a feeding pipe is fixedly connected to the center of the top of the housing, and a cover plate is fixedly connected above the feeding pipe. The upper end of the casing is fixedly connected with a horizontal connecting rod, the inner end of the horizontal connecting rod is fixedly connected with a heating box, the outer side of the heating box is fixedly connected with a number of electric heating ...

Problems solved by technology

[0003] For example, a vertical pressurized sludge drying treatment device proposed in patent application number 201810125063.8, which includes a housing, a feeding pipe is fixedly connected to the center of the top of the housing, and a cover plate is fixedly connected above the feeding pipe. The upper end of the casing is fixedly connected with a horizontal connecting rod, the inner end of the horizontal connecting rod is fixedly connected with a heating box, the outer side of the heating box is fixedly connected with a number of electric heating tubes, the upper part of the casing 1 is fixedly connected with a motor, and the output end of the motor is fixedly connected with a The transmission shaft, the left end of the transmission shaft is fixedly connected with the active bevel gear, the upper part of the heating box is fixedly connected with the fixed connecting rod, the middle part of the fixed connecting rod is connected with the longitudinal shaft, and the top of the longitudinal shaft is fixedly connected with the driven bevel gear. The movable bevel gear meshes with the driving bevel gear, and the bottom of the longitudinal shaft is fixedly connected with a stirring blade, which is a spiral stirring blade. Although the sludge of this equipment enters the heating box after being sieved through the sieve holes, it is more uniform. Avoid the drying of the sludge on the outside, and the inside is still wet and unevenly dried, but its drying depends entirely on the heat transfer of the electric heating tube to achieve drying. The drying efficiency is low, the energy consumption is high, and the cost is high, and it cannot be dried. Simultaneously achieve granulation

[0004] In addition, there is a patent application number 201811187924.1, a vertical integrated continuous treatment of sludge, oil, sludge and manure equipment for drying and incineration. It is composed of slag container, support, heating port, incineration chamber, drying chamber, blanking grid, groove, and blades. Among them, the top of the drying chamber is provided with an air outlet and a material inlet; the lower part of the drying chamber is provided with a combustion chamber , There is a support between the drying chamber and the combustion chamber; a furnace bar is provided at the lower part of the combustion chamber; a slag hopper is provided at the lower part of the furnace bar; The heating port; the support is fixed outside the lower part of the drying chamber; there is an agitator in the drying chamber, the upper part of the agitator is fixed on the top of the drying chamber, and the lower part is inserted into the groove on the support; There is a layer of blades, and a blanking grid is set correspondingly under the blades, and the blanking grid is fixed to the inner wall; it realizes the drying of the sludge in the drying chamber through the combustion chamber, which not only has low thermal efficiency, but also has a low drying efficiency. Very low, and can not achieve granulation while drying

[0005] At the same time, during the operation of existing equipment, the structure is often more complicated, which easily affects the reliability of equipment operation.
