Description

Sawdust sorting device

technical field

The utility model relates to a wood board production equipment, in particular to a sawdust sorting device.

Background technique

In the production of wood chip products such as pressed boards, the wood chips need to be sorted before the production of pressed boards. The current technology is to use the blower to blow and separate the method. This operation will generate a lot of dust. Since the operation room is open, so the dust Serious impact, indirect impact on the health of operators. Moreover, the separation efficiency of sawdust and iron filings is low by adopting the current technical method, and a large amount of sawdust is wasted.

Utility model content

In view of the above technical problems, the utility model provides a kind of dust-reducing sawdust sorting equipment, the specific technical solution is:

Sawdust sorting device, including a sorting chamber, one side of the sorting chamber has a plurality of outlets with different heights, and the outlets are equipped with a plurality of material distribution plates, and the material distribution plates are located in the separation chamber ; The bottom of the sorting chamber has a discharge port; the opposite side of the discharge port has a tuyere, and the described tuyere is connected to the air duct; the top of the sorting chamber has a feed port, and the feed port is connected to There is a feed pipe, and the feed pipe is connected to the hopper; the feed inlet is also equipped with a deflector, and the deflector is installed in the sorting chamber, and the upper end of the deflector is installed in the sorting chamber. On the side wall where the tuyere is located; the lower end of the deflector is lower than the upper end, forming an inclined shape.

The material distribution plate is installed obliquely on the discharge port, the higher end is located in the sorting chamber, and the lower end is connected to the discharge port.

The lower end of the deflector is also hinged with a screen; the other end of the screen is connected with a spring, and the spring is fixed on the inner wall of the sorting chamber.

The leveling blade in the feed pipe includes a rotating shaft on which a plurality of blades are evenly and symmetrically distributed, and the rotating shaft is installed horizontally.

A fan is also installed at the tuyere of the sorting chamber.

The air duct enters the sorting chamber, and the sawdust enters the sorting chamber from the hopper and the feeding pipe, and is dried in the sorting chamber through the deflector. After winnowing, the sawdust of different particle sizes is blown to the opposite separating board at different heights. , so as to achieve the purpose of sorting.

In order to screen out larger particles of sawdust, a sieve is provided.

The largest particles of sawdust fall to the bottom of the sorting chamber and are taken out from the discharge port.

In order to make the wind even and expand the air intake area, a fan is added.

The sawdust sorting device provided by the utility model utilizes winnowing to carry out grade screening, and the sawdust can be screened in a variety of particle sizes, and a large amount of dust will not be generated in the sealed sorting room.
