The drying equipment for PVC material of the utility model is further set as follows: a finished product tank is provided at the bottom of the vibrating screen.

Compared with the prior art, the utility model has the following beneficial effects: the drying equipment for PVC materials of the utility model does not need high-temperature heating, has many advantages such as high efficiency, low energy consumption, sufficient drying and good effect.

【Description of drawings】

Fig. 1 is the schematic diagram of the drying equipment of PVC material of the present invention.

【Detailed ways】

Please refer to the accompanying drawing 1 of the description, the utility model is a drying equipment for PVC materials, which consists of a screw conveyor 1, a first blower 2, a first heater 3, an airflow drying tower 4, and a first-stage cyclone separator 5 , the second blower 6, the second heater 7, the cyclone drying bed 8, the secondary cyclone separator 9 and the vibrating screen 10 and other parts.

Wherein, the screw conveyor 1 is connected to the airflow drying tower 4; the first blower 2 and the first heater 3 are connected to the airflow drying tower 4 in sequence.

The airflow drying tower 4 and the primary cyclone separator 5 are sequentially connected to the cyclone drying bed 8; the second blower 6 and the second heater 7 are also connected to the cyclone drying bed 8 in sequence.

The cyclone drying bed 8, the secondary cyclone separator 9 and the vibrating screen 10 are connected in sequence. A finishing tank 11 is provided at the bottom of the vibrating screen 10 .

The working principle of the drying equipment for PVC material of the utility model is as follows: the wet PVC material goes down to the screw conveyor 1, and is sent into the airflow drying tower 4 by the screw conveyor 1. At the same time, the high-speed airflow from the first blower 2 is heated to about 150°C by the first heater 3 and enters the airflow drying tower 4, and then enters the primary cyclone separator 5. Another high-speed airflow from the second blower 6 is heated to about 100°C by the second heater 7, and flows into the cyclone drying bed 8 together with the material from the primary cyclone separator 5. The PVC material and the hot air flow Rotating movement in the swirling drying bed 8, full contact, so that the moisture content of the material drops below 0.4%, and the temperature of the gas drops to about 60°C at the same time, the gas-solid two-phase flow coming out of the swirling drying bed 8, after two Grade cyclone separator 9 separates, and the finished PVC enters the finished product tank 11 through the vibrating screen 10 for packaging.

The specific implementation above is only a preferred embodiment of this creation, and is not intended to limit this creation. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this creation should be included in this creation. within the scope of protection.
