Description

Technical Field

[0001] The present invention relates to the technical field of airtightness detection, and particularly to an airtightness detection device for filter element manufacturing. Background Art

[0002] A filter element can separate impurity particles in a liquid, or enable different substance components to fully contact and accelerate the reaction, ensuring the normal operation of the equipment. When a fluid enters a filter element with a filter screen of a certain specification, its impurities are blocked, and the clean fluid flows out through the filter element.

[0003] During the production process of filter elements, in order to ensure the production qualification rate, it is necessary to detect the airtightness of the filter elements. When the traditional airtightness detection device is used, generally, the airtightness is detected by inflating and detecting the air pressure. During the detection, usually, workers need to place the filter element to be detected on the workbench. After the detection of the filter element is completed, the workers take it down and then place a new filter element for detection. Since the speeds of workers taking and re - placing the filter elements are different, if the workers are slow in taking and re - placing, the detection efficiency will be affected.

When the first movable plate 51 moves to the extreme point, at this time, the bottom of one of the inflation nozzles 511 is connected to the top of the filter element, and then stop the motor, and at the same time, supply power to the commutation module 52 through the power distribution module, and then supply gas to one of the inflation nozzles 511 through the valve group module, and then the airtightness of one of the filter elements can be detected. When the airtightness detection of one of the filter elements is completed, drive the motor again, and then drive the two first movable plates 51 to move in the opposite direction to the previous one, so that the first movable plate 51 on the top of one of the filter elements reaches the topmost position, and the first movable plate 51 on the top of the other filter element reaches the bottommost position.

A limiting block 549 is fixedly arranged inside the limiting ring 548. Limiting grooves for cooperating with the limiting block 549 are formed on the front and rear sides of the regulating rod 541.

[0027] A connecting ring 56 is fixedly arranged on the side of the rear limiting ring 548 away from the slider 547. A threaded rod 562 is rotatably arranged inside the connecting ring 56. The two ends of the threaded rod 562 penetrate through the front and rear sides of the connecting ring 56.

A hand wheel 563 is fixedly arranged at the rear side of the threaded rod 562.

[0028] When it is necessary to detect filter elements of different sizes, at this time, it is necessary to adjust the height of the first movable plate 51. First, rotate the hand wheel 563, which will drive the threaded rod 562 to rotate, so that the threaded rod 562 is separated from the threaded ring 561, and the two limiting rings 548 move in opposite directions, which will drive the limiting block 549 to move, so that the limiting block 549 is separated from the limiting groove, thus releasing the limitation on the regulating rod 541.

At the bottom of the connecting rope 558, a carabiner 557 is fixedly arranged. The carabiner 557 is connected to the first pull ring 556.

[0031] When the filter element detection on one side is completed, at this time, the first movable plate 51 on one side will move upward, thereby driving the second pull ring 559 to move upward, thereby driving the connecting rope 558 to move upward, thereby driving the carabiner 557 to move upward, thereby driving the first pull ring 556 to move upward, thereby driving the limiting plate 553 to move upward, so that the bottom end of the limiting plate 553 moves out of the limiting hole, releasing the limit on the push rod 552. Then, through the return spring, the baffle 550 is driven to move forward, thereby driving the push rod 552 to move forward. Then, through the push rod 552, the detected filter element is pushed forward. At this time, the filter element to be detected can be placed, and it is not necessary to remove the detected filter element, reducing the workload of the staff. Until the first movable plate 51 on this side reaches the lowest position, the filter element to be detected is released.

[0032] On the top of the placement seat 4, a groove is provided. Inside the groove, the top of the placement plate 41 is slidably arranged up and down. The bottom of the placement plate 41 is connected to the bottom of the groove through a first spring telescopic rod 42.

[0035] By providing the flow guide plate 11, after the filter element is pushed forward, it will pass through the flow guide plate 11 and then move into the collection box 123.

[0036] Working principle: When airtightness detection of the filter element is required, first place two filter elements to be detected on the top of the placement seat 4, drive the motor, which drives the first gear 531 to rotate, then drives a plurality of tooth blocks 530 to slide up and down, and then drives the second movable plate 535 to slide up and down. When the second movable plate 535 reaches the extreme point, the second movable plate 535 will move left and right inside the movable frame 534. After the movement is completed, the second movable plate 535 will move in the opposite direction to before, driving the movable frame 534 to move reciprocally, driving the first toothed plate 536 to move reciprocally up and down, driving the second gear 537 to rotate reciprocally, driving the third gear 538 to rotate reciprocally, driving the second toothed plates 539 on both sides of the third gear 538 to move reciprocally up and down, and the moving directions of the left and right second toothed plates 539 are opposite directions, driving the two movable columns 54 to move reciprocally in opposite directions, driving the two first movable plates 51 to move reciprocally in opposite directions, causing one inflation nozzle 511 to move downward and the other inflation nozzle 511 to move upward. When the first movable plate 51 moves to the extreme point, the bottom of one inflation nozzle 511 is connected to the top of the filter element. At this time, the motor stops working, and at the same time, power is supplied to the commutation module 52 through the power distribution module, and gas is supplied to one inflation nozzle 511 through the valve group module, so that one of the filter elements can be detected. After one of the filter elements is detected, the motor is driven again, driving the two first movable plates 51 to move in the opposite direction to just now, so that the first movable plate 51 on the top of one filter element reaches the topmost position, and the first movable plate 51 on the top of the other filter element reaches the bottommost position. At this time, the other filter element can be detected. While detecting, the detected filter element can be removed, and the filter element to be detected can be placed. At this time, the replacement time is shortened, thereby improving the detection efficiency. At the same time, it can also avoid the problem of low efficiency easily caused by different workers having different replacement speeds of the filter element, ensuring the consistency of the detection efficiency. After the filter element on one side is detected, the first movable plate 51 on one side will move upward at this time, thereby driving the second pull ring 559 upward, thereby driving the connecting rope 558 upward, thereby driving the climbing buckle 557 upward, thereby driving the first pull ring 556 upward, thereby driving the limiting plate 553 upward, so that the bottom end of the limiting plate 553 is removed from the limiting hole, releasing the limit on the push rod 552, and then driving the baffle 550 forward through the return spring, thereby driving the push rod 552 forward, and then pushing the detected filter element forward through the push rod 552. At this time, the filter element to be detected can be placed, and it is not necessary to remove the detected filter element, reducing the workload of the staff. Until the first movable plate 51 on this side reaches the lowest position, release the filter element to be detected.
