Background technique

Raw materials are the material basis for the production of chemical products and are the participants in chemical reactions. Raw materials not only directly affect the performance and cost of products, but also directly affect the process and process conditions, affect the input of human and financial resources, and also affect the consumption of materials. and energy consumption. In the production process of raw materials for many industrial products, drying is an important part of the production process. Water content is one of the main quality indicators of many products. In order to achieve the required water content, most products need a certain In the production process of food, chemical, pharmaceutical and other products, the quality of the drying process directly affects the performance, shape, quality and cost of the product.

The heating and drying of powder materials, due to the fine particles, poor heat transfer performance, when the material distribution is uneven, it is easy to appear uneven heating, and it is easy to fly, and the powder particles are easy to burn when flying to the drying cylinder, which affects the quality of the powder materials , Generally, factories adopt drying in the form of drying room, but the drying cycle in drying room is often long, the output is low, the labor intensity is high, the working conditions are poor, and the energy consumption is high.

Contents of the invention

In view of the above situation, the purpose of this utility model is to provide a drying device for powder materials, which has uniform heating, short drying time, and powder particles will not stick to the drying device, so as to ensure the drying quality of powder materials.

A drying device for powder materials of the utility model includes a drying mechanism and a vibration mechanism. The drying mechanism includes a drying box, several drying plates and an air heater. The upper part of the drying box is provided with a material inlet, and the material is A downward sloping baffle is fixed on the drying box at the connection between the inlet and the drying box, and the bottom of the drying box is provided with a material outlet, and the drying plates are fixed in the drying box from top to bottom. On the side wall of the drying box, the side wall corresponding to the fixed side of the drying box is fixed with a downward-sloping plate. The hot gas outlet of the air heater passes through the material inlet of the drying box through a pipe, and the end of the pipe passes into the On the upper part of the drying box, the gas inlet of the air heater is connected with a fan. The vibration mechanism is installed at the bottom of the drying box, and the vibration mechanism drives the drying box to vibrate. The vibration mechanism includes a motor, a vibrator and a shock absorbing spring. There are no less than 2 damping springs, which are arranged at the bottom of the drying box, and the motor drives the vibrator to vibrate through the belt, and the vibrator drives the drying box to vibrate.

Preferably, the bottom of the drying box is inclined, so that the materials can reach the material outlet quickly and smoothly without accumulating materials.

Preferably, there are 4 damping springs, which are arranged on the 4 corners of the bottom of the drying box. The box vibrates evenly, the drying effect is good, the material falls evenly, and the uniform product quality is guaranteed.

Preferably, the included angle between the plate body fixed on the side wall of the drying box and the side wall is 25°, which can effectively prevent the powder material from sticking to the side wall of the drying box, and is also easy to clean the side wall.

In the powder material drying device of the utility model, the hot air inlet of the air heater is connected with the material inlet of the drying box, and the hot air is blown downward at the same time when the material is added, and the agglomerated material can be blown away and dried at the same time, and the inside of the drying box is dried. There are holes on the drying plate to make the powder material fall, and at the same time, it can delay the material falling time and ensure the drying quality. The powder falls smoothly, and the baffle installed at the material inlet of the drying box prevents the material from flying out along the material inlet to a large extent. The baffle set on the side wall of the drying box prevents the material powder from sticking to the drying box as much as possible At the same time, the drying box is vibrated by the vibration mechanism to further prevent the material powder from sticking to the box.

The powder material drying device of the utility model has a simple method, a large transfer surface area between the gas and the material, a high volume mass transfer coefficient, a high drying rate, a short contact time, and a high thermal efficiency. Drying, less stirring of the material, keeping the crystal shape intact, will not cause damage to certain components of the powder material, and ensure product quality.

Detailed ways

The powder material drying device of the present utility model is further described below in conjunction with the accompanying drawings;

As shown in Figures 1 and 2, a device for drying powdery materials includes a drying mechanism and a vibrating mechanism. The drying mechanism includes a drying box 1, a number of drying plates 2 and an air heater 3. The drying box 1 The bottom of the drying box 1 is provided with a material inlet 4, and the drying box 1 at the junction of the material inlet 4 and the drying box 1 is fixed with a downward-sloping baffle plate 5, and the drying box 1 A material outlet 6 is provided at the bottom, holes 12 are provided on the plurality of drying trays 2, and several drying trays 2 are fixed on the inner side wall of the drying box 1 in relative staggered layers from top to bottom, and the drying box 1 and the drying tray 2 The side wall corresponding to the fixed side is fixed with a downwardly inclined plate body 7, the angle between the plate body and the side wall is 25°, and the hot gas outlet of the air heater 3 passes through the material inlet of the drying box through a pipe 4. The end of the pipeline leads into the upper part of the drying box 1, and the gas inlet of the air heater 3 is connected with a fan 8. The vibration mechanism is installed at the bottom of the drying box 1, and the vibration mechanism drives the drying box 1 to vibrate. The vibration mechanism includes Motor 9, vibrator 10 and damping spring 11, said damping spring 11 is not less than 2, is arranged on the bottom of drying cabinet 1, drives vibrator 10 to vibrate by motor 9 through belt, and vibrator 10 drives drying cabinet Body 1 vibrates.

During concrete implementation, turn on motor 9, blower fan 8 and heater 3, add powder grain material from material inlet 4 on drying box body 1 top, blower fan 8 enters drying box body 1 after wind is blown into heater 3 for heating, and hot blast flows Down blowing, when the material is added, the wind blows the material away, and blows away the agglomeration of the powder material. The material enters the drying box 1 and falls on the drying plate 2, and falls along the hole of the drying plate 2. At the same time, under the action of the vibration mechanism Next, the vibration of the drying box 1 prevents the residence time of the material from being too long, avoiding the agglomeration of the material, and the material finally falls to the bottom of the drying box 1, and the dried material is obtained through the material outlet 6 at the bottom of the drying box 1.
