Abstract

A drying oven for quickly drying large-particle solids, comprising an oven body (5), an operation interface (6), support legs (7), a power cord (8), a drying bin (1), a roller (2), a roller shaft (3), and a drying platform (4). The drying platform (4) is disposed inside the drying bin (1); the roller (2) is located in the drying bin (1) and directly above the drying platform (4); the roller (2) is internally hollow, and a notch accounting for 1/4 of the volume of the roller (2)is formed on the side wall of the roller (2); the roller (2) is connected to the inner wall of the drying bin (1) by means of the roller shaft (3); a heating circuit, a temperature controller, and a motor are provided inside the oven body (5); one end of the roller shaft (3) is connected to the motor. The drying oven is applicable to quickly dry large-particle solids, thereby effectively improving the drying efficiency by increasing the contact areas between the surfaces of particle solids and air during a drying process.

Description

Drying box for quickly drying large granular solids

Technical field

The present invention relates to a drying oven for rapidly drying large particulate solids.

Background technique

When drying large granular solids, the particulate solids are stacked on the drying table due to static deposition, so that only the upper solids can be dried faster during the drying process, and the solids deposited underneath are directly contacted by different air. The drying rate is slower, which affects efficiency.

Summary of the invention

It is an object of the present invention to provide a drying oven for rapidly drying large particulate solids, which aims to solve the above problems.

In order to achieve the above object, the technical proposal of the present invention is to design a drying box for rapidly drying large particle solids, including an oven body, an operation interface, a support leg, a power line, a drying chamber, a drum, a drum shaft, and drying. The drying table is disposed inside the drying chamber; the drum is located in the drying chamber, directly above the drying table; the inside of the drum is hollow, and the side wall of the drum has a gap of 1/4 of the volume of the drum; The drum is connected to the inner wall of the drying chamber through a drum shaft; the oven body is internally provided with a heating circuit, a temperature control device and an electric motor; and one end of the drum shaft is connected to the motor.

Preferably, the inner wall of the drum is coated with a layer of polytetrafluoroethylene.

Preferably, the surface of the drying table is coated with a layer of polytetrafluoroethylene.

The process of rapid drying of large granular solids: when large particles of solids are stacked on the drying table, the motor drives the drum shaft to rotate, the drum shaft rotates to drive the drum to rotate, and during the rotation of the drum, the large solid particles on the drying table will be dried. Scraping into the interior of the drum, at which time large particulate solids entering the interior of the drum move as the drum rotates. After the drum has been rotated for one week, the large particulate solids in the drum fall back from the gap to the drying station. The above process loop occurs. In the above process, the large particle solids keep moving, increasing the contact area of the particle surface with the hot air and speeding up the drying speed.

The invention has the advantages and beneficial effects that the drying box for quickly drying large particle solids is suitable for rapidly drying large particle solids, increasing the contact area of the surface of the solid particles with air during the drying process, and effectively improving the drying. Dry efficiency. In addition, the surface of the inner wall of the drum and the surface of the drying table are coated with polytetrafluoroethylene, which effectively prevents the large particle solids from adhering to the inner wall of the drum and the surface of the drying table, and at the same time, coating the poly 4 for a corrosive substance. Vinyl fluoride can avoid corrosion and effectively extend the service life.
