Collection box for dust collector

The present invention relates to a dust collector, and more particularly to a collection box for a dust collector.

In industrial production sites (such as wood factories) where chipping or dust is easily generated, a dust collector for automatically collecting chips and dust is usually installed. A common dust collector includes a collection box having an air inlet, an upper air outlet, and a lower air outlet. The air inlet is connected to a flow guiding device (for example, a blower), and the upper air outlet is ventilated. The dust collecting container is connected, and the lower air outlet is connected to a collecting container. The flow guiding device discharges air mixed with debris and dust into the collecting box, and the air flows upward into the dust collecting container, and then is discharged to the dust collecting machine through the dust collecting container. In the foregoing process, the weight is relatively high. Large debris is dropped by the gravity container and falls into the chip container. The smaller weight debris and dust are blocked by the dust collecting container and adhere to the inner surface of the dust collecting container.

However, when the conventional dust collector is in operation, not only the sway of the machine is too large, but also the backflow phenomenon is easily generated in the swarf container, so that the debris entering the collection box is not easily dropped into the swarf container, and when the swarf container is When the accumulated debris is about seven minutes full, the debris is easily carried into the dust collecting container by the upward airflow; in other words, the dust collector is not effective in separating the debris and the dust, so the dust collecting container will Excessive debris enters, making the inner surface of the dust collecting container easy to generate chips and quickly reducing its gas permeability, so that the dust collector can be cleaned as needed to reduce its working efficiency.

In view of the above-mentioned deficiencies, the main object of the present invention is to provide a collecting box for a dust collecting machine, which can make the dust collecting machine sway less and separate the debris and dust.

In order to achieve the above object, the present invention provides a collecting box for a dust collector, comprising a body, the body having an accommodating space, and an air inlet, an upper air outlet and a lower air outlet communicating with the accommodating space; The collecting box is further characterized by a partition cover having an outer surface and an inner surface, the partition cover is disposed in the receiving space of the body, and the outer surface is opposite to the air outlet above the body The inner surface is opposite to the air outlet below the body. Thereby, the air inlet, the upper air outlet and the lower air outlet of the collecting box can be respectively connected with a flow guiding device, a gas permeable dust collecting container and a collecting container to form a dust collecting machine; the guiding device can be The air mixed with debris and dust is sucked into the accommodating space of the collecting box, and the air flows upward to the dust collecting container, and the heavy debris is dropped from the partition cover and the body Falling into the collecting container, and even if the collecting container is filled with debris, the scrap is not easily rolled up again, so that the dust collector not only separates debris and dust, but also has a swaying degree. It will also decrease.
