Description

Anti-Clog Rotary Dryers

technical field

The present application relates to a drying device, in particular to an anti-clogging rotary dryer.

Background technique

At present, the dryer mainly vaporizes and escapes the moisture (generally referring to water or other volatile liquid components) in the material by heating to obtain a solid material with a specified moisture content. In many chemical solid products, moisture is strictly controlled. This requires the use of a dryer to make the product meet the requirements. The more common rake dryer has many problems, such as long drying time for materials, high energy consumption, and easy wall sticking, etc. Especially for granular materials, this kind of dryer can easily damage the original shape of the particles when drying.

Ordinary dryers use hot drying media to directly contact wet materials, transfer heat in a convective manner, and take away the generated steam. The thermal efficiency is low, and during the drying process, certain gases are harmful to the human body and harmful to the human body. The pollution of the environment, and the gas entering the dryer may cause the product to be polluted, which further affects the quality of the product.

In the existing rotary dryer, the inert gas inlet usually enters horizontally. During the feeding process and the rotating process, the material is easy to enter from the air inlet and cause blockage.

detailed description

The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the drawings in the embodiments of the present invention. Apparently, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Fig. 1, the anti-clogging rotary dryer includes a frame 1 and a tank body 3 having a feed inlet and a discharge port 2, the tank body 3 is rotatably arranged on the frame 1, and the tank body 3 The axis of rotation is located in the horizontal direction. The dryer also includes a motor for driving the tank body to rotate, an air intake pipe 5 and an exhaust pipe 6 extending into the tank body. The air intake pipe 5 is relatively fixed to the frame, and the air intake pipe 5 is located on One end of the body opens downward.

The air intake pipe 5 includes a main body 501 located in the tank and a bent part 502 formed by bending downward from the end of the main body. The main body 501 extends obliquely upward from the end entering the tank.

In this technical solution, the opening at the end of the air inlet pipe is downward, so as to prevent the top material from being put in and the material during the rotation from entering the air inlet pipe and forming a blockage.

A supporting rod 7 is also extended in the tank, and the supporting rod 7 is arranged side by side with the main body 501 , and the main body 501 is fixed on the supporting rod 7 .

In this technical solution, in this technical solution, the support strength of the intake pipe is improved by the support rod.

Air intake pipe 5 and exhaust pipe 6 are set on the same side of tank body 3, and cover 8 is arranged between intake pipe 5, exhaust pipe 6 and tank body 3 sidewalls, and cover 8 is fixed with tank body 3, enters The air pipe 5 , the exhaust pipe 6 and the cover 8 are sealed by packing 9 , and the outside of the packing seal 9 is fixed by lock nuts 10 , and a lock nut window 801 is opened on the cover 8 .

A heating space 301 is formed on the side wall of the tank body 3 , and a heating circuit is formed between the heating space 301 and the external heat source inlet 302 and heat source outlet 303 .

Preferably, the heating medium in this embodiment is hot water, and the hot water enters the heating space through the heat source inlet connected to the heating space and flows out from the heat source outlet.

One end of the exhaust pipe 6 located outside the tank body is connected to an air cleaning device 601 . The pollution of the environment and the harm to the operator are prevented.

The tank body 3 is also provided with a point inspection and maintenance port 302 corresponding to the feed port and the discharge port.

When the rotary dryer in this embodiment is in use, the tank body is driven to rotate slowly through the frequency conversion motor, and the material is heated through the heating space, so that the material is continuously mixed and dried evenly, and the drying speed of the material is further accelerated. At the same time, the air intake pipe, The inert gas (nitrogen) is passed into the tank, and then the gas in the tank is discharged to the air purification device through the exhaust pipe, which improves the quality of the dried material and reduces the harm of the gas in the tank to the human body and the pollution to the environment. In addition, in this embodiment, a point inspection and maintenance port is provided at the position corresponding to the inlet and outlet of the tank body, which is convenient for observation and maintenance. Therefore, the drying time of the material in the rotary dryer of this embodiment is greatly shortened, and the residence time of the material in the tank is also greatly shortened. The chance of collision between them is also significantly reduced, so the original shape of the material will not be damaged basically. At the same time, the direct discharge of the dried gas is prevented, which will cause environmental pollution and harm to the health of operators. In addition, the opening at the end of the air intake pipe is facing downwards, so as to prevent the material from the top and the material during the rotation from entering the air intake pipe and causing blockage.
