Description

Technical Field

[0001] This utility model relates to the field of air cushion conveyor technology, specifically to an air cushion belt conveyor circulating air supply and dust removal device. Background Technology

[0002] Air cushion belt conveyors achieve efficient material transport by suspending materials in an air film and are widely used in the bulk material handling industry. However, the transport process typically generates dust. Existing dust removal technology involves installing a (non-powered) dust collector connected to the middle section of the air cushion conveyor. The supply fan blows gas into the air cushion conveyor, filling the discs with dust-laden gas. Under the pressure of the circulating airflow, the dust-laden gas automatically enters the dust collector and filter. The filter element in the dust collector filters the incoming gas, removing the dust. The clean gas is discharged through the outlet of the dust collector and then re-enters the inlet of the supply fan through a connecting duct, forming a complete supply and exhaust air cycle. To prevent insufficient airflow from the dust collector to the supply fan during operation, a makeup air pipe (directly connected to external air) is installed on the connecting duct to supplement the supply fan with any insufficient airflow.

[0003] However, existing non-powered dust collection devices have significant drawbacks: their dust collection boxes are connected to the inside of the air cushion machine via a single-sided air inlet, and the dust-laden airflow is discharged to the supply fan through the outlet after being filtered by the filter element. Due to the single airflow path and the filter element's long-term exposure to a high-concentration dust environment, it is highly prone to clogging. When the dust accumulation on the filter element exceeds a critical value, the machine must be stopped and the filter element removed for manual cleaning. This process forces the air cushion machine to shut down, severely impacting the continuity of the production line. Therefore, there is a need to provide an air cushion belt conveyor circulating air supply dust collection device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a circulating air supply and dust removal device for an air cushion belt conveyor, so as to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a circulating air supply and dust removal device for an air cushion belt conveyor, comprising:

[0006] The dust collector is a non-powered dust collector box and a connecting air duct. The air inlet at the lower end of the dust collector box is fixed on the upper plate groove in the middle section of the air cushion machine and communicates with the inside of the air cushion machine. One end of the connecting air duct is fixed at the air outlet on the upper side of the dust collector box, and the other end is fixed at the air inlet of the air supply fan of the air cushion machine itself.

[0007] The partition assembly includes a partition plate, an annular support plate, a first insertion hole, a baffle, a push rod, and a second insertion hole. The partition plate is fixed to the middle of the inner side of the non-powered dust collector box, the annular support plate is fixed to the lower end of the non-powered dust collector box and located below the partition plate, the first insertion hole is opened at the lower end of the partition plate, the baffle is inserted into the first insertion hole, the second insertion hole is opened on one side of the non-powered dust collector box, one end of the push rod is fixed to the middle of the side of the baffle, and the other end is inserted into the second insertion hole.

[0008] Furthermore, the separating assembly also includes a connecting plate, a mounting hole, and a screw. The connecting plate is fixed to the middle of one end of the baffle, the mounting hole is opened in the middle of the connecting plate, one end of the screw is fixed to one end of the push rod, and the other end is inserted into the mounting hole and tightened by a nut.

[0009] Furthermore, the separating assembly also includes a first sealing ring, which is fixed to the end of the push rod near the screw.

[0010] Furthermore, the separator includes a connecting ring and a second sealing ring. The connecting ring is screwed onto the other end of the push rod away from the screw, and the second sealing ring is sleeved on the push rod and fits against the side of the connecting ring.

[0011] Furthermore, the other end of the connecting duct away from the non-powered dust collector is connected to a makeup air duct, and both the connecting duct and the makeup air duct are connected to relevant air blowers in the middle section.

[0012] Furthermore, it also includes a positioning component, which includes an angle iron, a third insertion hole, a fourth insertion hole, and a rod. The angle iron is fixed to the outside of the non-powered dust collector and is located above the second insertion hole. The third insertion hole is opened in the middle of one side of the angle iron. There are two fourth insertion holes, which are respectively opened at both ends of the push rod. The rod is inserted into the third insertion hole and the fourth insertion hole.

[0013] Furthermore, the positioning component also includes a pull ring, which is fixed to the upper end of the insertion rod.

[0014] Furthermore, when the first sealing ring is attached to the inner wall of the non-powered dust collector, the insertion rod is inserted into the fourth insertion hole near the first sealing ring; when the second sealing ring is attached to the outer wall of the non-powered dust collector, the insertion rod is inserted into the fourth insertion hole near the second sealing ring.

[0015] This utility model has the following beneficial effects:

[0016] This utility model, through its partition component, allows for the following steps: Insert the baffle into the first insertion hole, then insert the push rod into the second insertion hole, install the first and second sealing rings, insert the screw into the mounting hole of the connecting plate, tighten the nut, push the baffle completely to one side of the partition, rotate the connecting ring to push the second sealing ring against the outer wall of the non-powered dust collector. After a period of use, pull the push rod in the second insertion hole to move the connecting plate, which in turn moves the baffle to the annular support plate on the other side of the partition. At this point, the first sealing ring is against the inner wall of the non-powered dust collector. The door on the side without the baffle can then be opened to replace the filter element inside. After a period of use, the filter element on the other side can be replaced following the same steps. This design enables online filter element replacement without machine downtime, effectively avoiding production line interruptions caused by filter element clogging in traditional dust collection devices.
