Description

Technical Field

[0001] The utility model relates to the technical field of solid waste treatment, and more specifically, it relates to a disk dryer for treating incineration residues. Background Art

[0002] Incineration technology is one of the mainstream technologies for the safe and efficient disposal of current industrial hazardous waste. Through high-temperature decomposition and combustion, hazardous waste is oxidized and burned to ashes under high temperature in a closed environment to achieve the purpose of reduction. At present, when a hazardous waste incinerator is in use, although heat can be recovered and tail gas can be treated, some inorganic substances in the hazardous waste cannot be completely burned during the incineration process, and a small amount of residues are carried out by a slag discharge machine through a water-cooling method. After water-cooling, the water content of the residues is relatively high, posing environmental risks for secondary disposal and temporary storage.

[0003] For example, a solid waste high-efficiency drying device disclosed in the authorized announcement number CN206831941U controls the operation of an air pump and a heating wire, and then controls the rotation motor in a moving device to rotate clockwise and counterclockwise to drive a nozzle to move left and right to uniformly air-dry the solid waste to be dried, achieving the effects of low energy consumption, small odor generation, small chemical agent dosage, small treatment difficulty, low operating cost, and stable treatment effect.

[0004] However, during the use of the above solution, the contact area between the solid waste and the ejected gas is limited, resulting in low drying efficiency when drying the solid waste and affecting the working efficiency of the recycling work. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a disk dryer for treating incineration residues that can fully dry the fixed waste residues.

[0006] To achieve the above purpose, the present utility model provides the following technical solutions:

[0007] A disk dryer for treating incineration residues includes a main machine cylinder body. The main machine cylinder body has a cavity inside, and a drying device is arranged in the cavity. An inlet and an exhaust port are opened on the upper end face of the main machine cylinder body, and an outlet is opened on the lower end face of the main machine cylinder body.

[0008] The drying device includes a plurality of drying disk groups and a driving mechanism. The drying disk groups include large drying disks and small drying disks, which are arranged alternately. A material dropping port is opened in the middle of the large drying disks. The driving mechanism includes a rotary cylinder and a main shaft, and the large drying disks and the small drying disks are connected to the main shaft.

[0009] A turning mechanism is arranged on the first group of drying disk groups.

[0010] The exhaust port is connected to a dust removal system, and the exhaust port and the dust removal system are connected through an exhaust pipe.

[0011] The present utility model is further configured such that: storage cavities are provided in the large drying tray and the small drying tray, and a heat transfer medium is provided in the storage cavities. The heat transfer medium includes, but is not limited to, saturated steam, hot water, and heat transfer oil.

[0012] The present utility model is further configured such that: the turning mechanism includes a driving motor, a turning arm, and turning blades. The driving motor is disposed on the upper end surface of the main body cylinder. The output end of the driving motor is connected to the turning arm, and the other end of the turning arm is connected to the turning blades. The turning blades are disposed on the upper end surfaces of the large drying tray and the small drying tray.

[0013] The present utility model is further configured such that: the dust removal system includes a pulse cloth bag and a dust collector, and a discharge port is provided on the pulse cloth bag.

[0014] The present utility model is further configured such that: a docking hole communicating with the cavity is provided on the side wall of the main body cylinder, and a fresh air compensation heater is connected to the docking hole.

[0015] The present utility model is further configured such that: a support is connected to the side of the drying tray group, and one end of the support is connected to the inner wall of the main body cylinder.

[0016] The present utility model is further configured such that: a visible door is provided on the main body cylinder, and the visible door is made of a transparent material.

[0017] Compared with the deficiencies of the prior art, the beneficial effects of the present utility model are as follows:

[0018] By alternately arranging large drying trays and lower drying trays with different diameters, each layer of drying tray can be separately passed through a heat medium or a cold medium to heat or cool the material. The temperature of the material can be accurately and easily controlled, and the residence time of the material can be precisely adjusted.

[0026] An inlet and an exhaust port 4 are opened on the upper end face of the main body cylinder 1, and an outlet 5 is opened on the lower end face of the main body cylinder 1. The material is input through the feeding port 3, and the dried material is discharged from the outlet 5. The dried material discharged from the outlet 5 can be directly packaged.

[0027] The drying device includes a plurality of drying disk groups and a driving mechanism. A bracket 20 is connected to the side of the drying disk group. One end of the bracket 20 is connected to the inner wall of the main body cylinder 1. The drying disk group includes a large drying disk 6 and a small drying disk 7. A storage cavity 12 is opened in the large drying disk 6 and the small drying disk 7. A heat conduction medium is provided in the storage cavity 12. The heat conduction medium includes but is not limited to saturated steam, hot water, and heat conduction oil. The material is heated or cooled through the heat conduction medium, so that the temperature of the material can be accurately and easily controlled.

[0028] The large drying trays 6 and small drying trays 7 are arranged alternately. A material dropping opening 8 is formed in the middle of the large drying tray 6. The driving mechanism includes a rotary cylinder 9 and a main shaft 10. The large drying trays 6 and small drying trays 7 are connected to the main shaft 10. Through the arrangement of the cylinders of the large drying trays 6 and small drying trays 7, the materials can continuously flow through the entire dryer.

[0029] A turning mechanism is provided on the first group of drying tray groups. The turning mechanism includes a driving motor 13, turning arms 14 and turning blades 15. The driving motor 13 is placed on the upper end surface of the main machine cylinder 1. The output end of the driving motor 13 is connected to the turning arm 14.

The turning arm 14 with the turning blade 15 makes a rotary motion to continuously turn over the materials. The materials flow along an exponential spiral line on the surface of the small drying tray 7. The materials on the small drying tray 7 are transferred to the outer edge and fall to the outer edge of the lower large drying tray 6 at the outer edge. The materials on the large drying tray 6 move inward and fall into the next-layer small drying tray 7 from the middle material dropping opening 8. The large and small drying trays 7 are arranged alternately up and down, so that the materials can continuously flow through the entire dryer. During use, the heat-conducting medium is added to the large drying tray 6 or small drying tray 7 manually. The heat-conducting medium enters from one end of the drying tray and is discharged from the other end. The dried materials fall from the last-layer large drying tray 6 to the bottom layer of the housing and are finally transferred to the discharge port 5 by the rake blades for discharge. The moisture escapes from the materials and is discharged from the exhaust port 4 provided on the top cover, and is discharged into the air after passing through the dust collector 17. The dried materials discharged from the bottom layer can be directly packaged.
