Abstract
Description
Technical Field
[0001] The utility model relates to a honeycomb transmission suction box dust accumulation prevention device, belonging to the technical field of textile dust filtering equipment. Background Art
[0002] The honeycomb dust filter equipment is equipped with a transmission suction box, and there are multiple small suction arms and small suction nozzles on the transmission suction box. When the transmission suction box moves, the small suction arms and small suction nozzles enter the honeycomb filter bag, and the wind force of the dust collecting fan sucks out the short lint and dust that are blocked when filtering the dust-containing air on the filter bag. The airflow containing short lint and dust is sent to the dust collector for filtration and collection through the transmission suction box and the air duct. When individual small suction arms and small suction nozzles are blocked, the airflow speed of the transmission suction box air duct is insufficient, and the short lint dust will slowly settle at the bottom of the transmission suction box, blocking the total suction port at the bottom of the transmission suction box, resulting in all small suction arms and their small suction nozzles having no suction force, which directly affects the normal operation of the dust filter equipment.

DETAILED DESCRIPTION
[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0015] like Figure 1 , 2As shown in Figures 3 and 4, a honeycomb transmission suction box dust accumulation prevention device in this embodiment, a transmission suction box 1 and a honeycomb filter bag 4 are provided in the dust filter box body, and the transmission suction box 1 is connected to a small suction nozzle 3 through a small suction arm 2, and the three are interconnected. The transmission suction box 1 is connected to the dust filter box body through a guide rail slider mechanism, and the guide rail slider mechanism drives the transmission suction box 1 to move in the dust filter box body to achieve the small suction nozzle 3 approaching or moving away from the honeycomb filter bag 4. A total suction port 1.1 is provided on the transmission suction box 1, and the total suction port 1.1 is connected to the dust collector through a dust collecting pipe 5; the dust collector is opened, so that the dust and short fluff in the honeycomb filter bag 4 are sent to the dust collector for filtration and collection through the transmission suction box 1 and the dust collecting pipe 5. The bottom of the transmission suction box 1 is provided with a dust prevention device, which includes an air supply valve 6. The bottom of the transmission suction box 1 is provided with an air supply port. The transmission suction box 1 is provided with a horizontally arranged fixed shaft 7. The air supply valve 6 is fixed on the fixed shaft 7. The fixed shaft 7 is provided with a torsion spring 10. One end of the torsion spring 10 is fixedly connected to the air supply valve 6. A limit block 9 is provided on the outside of the air supply port. A travel block 8 is provided on the inner wall of the side plate 11 of the dust filter box body. When the guide rail slider mechanism drives the transmission suction box 1 to move to the travel block 8, the travel block 8 pushes the air supply valve 6 and the fixed shaft 7 to rotate, so that the air supply valve 6 is away from the air supply port, that is, the air supply port is opened, and the air flow enters the transmission suction box 1 through the air supply port and then flushes the dust settled at the bottom of the transmission suction box. Under the action of the torsion spring 10, the air supply valve automatically resets. When the air supply valve rotates and hits the limit block and stops rotating, the air supply port is in a blocked state.
[0016] The above-mentioned limit stop has a limiting effect on the resetting of the air supply valve.
[0017] During the dust suction operation of the transmission suction box feeding forward and backward, each time the transmission suction box moves to the stroke collision block position, the air supply valve at the bottom of the transmission suction box is automatically opened, that is, the air supply port is opened, and a large amount of airflow enters the transmission suction box air suction duct at high speed through the air supply port, flushing the dust and short fluff settled at the bottom of the transmission suction box, which can achieve a good automatic dust prevention effect; when retreating, the air supply valve automatically closes the air supply port under the action of the torsion spring, which does not affect the air volume of the small suction nozzle, ensuring the smoothness of the transmission suction box air suction duct and the normal operation of the dust filtering equipment. The present application has a simple structure and is easy to operate, avoiding blockage of the suction arm and the suction nozzle, and ensuring the normal operation of the dust filtering equipment.
[0018] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
