Description

Technical Field

[0001] The utility model belongs to the field of filtering, relates to a dust removal filter, and specifically relates to a dust removal filter device. Background Art

[0002] In the injection molding industry, whether it is a dryer or a feeder, filters are used to collect dust to protect the rear-end fan and other parts. The filter element of a common filter is installed in the cylindrical shell of the filter. After installation, the position of the filter element is fixed and unchanged. Usually, there are the following main problems: In actual use, because the filter element of the filter does not move, and the air inlet pipe is directly blown in by a round tube, the wind speed is very fast, and one side of the filter element of the filter will be subjected to wind pressure for a long time. At the same time, the powder and granular material will hit the filter element, and the filter element is prone to damage, which greatly reduces the life of the filter element; at the same time, because it cannot play a protective role, it will cause damage to parts such as the fan. In addition, since the windward surface is concentrated on one surface, dust quickly accumulates on this surface, causing the part to quickly lose its ventilation function, increase pressure loss, and affect the air volume. In addition, the dust storage space in the filter housing is small, and dust will quickly fill the entire space, making cleaning cumbersome and inconvenient. Utility Model Content

The dust removal and filtering device comprises a housing 1 and a filter element 7, wherein the filter element 7 is rotatably mounted in the housing 1, and the housing 1 is provided with an air inlet pipe 5. Figure 2As shown, the central longitudinal axis of the air inlet pipe 5 is located on the tangent of the outer circle of the filter element 7, so that the filter element 7 can rotate with the wind entering the air inlet pipe 5, wherein the filter element rotates circumferentially. Based on this design, the filter element can move with the wind, reducing the influence of wind pressure and the impact of dust materials, and at the same time, the powder on the filter element can be discharged to the bottom of the shell in time, without clogging the filter, so as to better collect the powder.

Each seal can prevent the entry of powder and granules.

[0023] In this embodiment, the mounting bracket 11 is further provided with a locking mechanism 17 for limiting axial movement.

[0024] In this embodiment, if Figure 1 and Figure 2As shown, the air inlet pipe 5 is located at the top of the shell 1, the air outlet pipe 14 is located at the side of the shell 1, and a dust collector 9 is arranged at the bottom of the shell 1 to increase the powder storage capacity and significantly reduce the dust cleaning cycle.
