Description

Technical Field

[0001] The present invention relates to the technical field of melt-blown filter elements, and in particular to a melt-blown filter element that is easy to maintain. Background Art

[0002] The meltblown filter element is a tubular filter element made of non-toxic and odorless polypropylene particles, which is heated, melted, spun, pulled, and formed. If the raw material is mainly polypropylene, it can be called a PP meltblown filter element. It is only used in large quantities in water purification. It also has excellent chemical compatibility and is suitable for filtering strong acids, strong alkalis and organic solvents. It has strong pollution-absorbing capacity, long service life and low cost.

[0003] It should be noted that when the meltblown filter element is in use, a filter element cover is arranged outside it, a top cover is installed on the top side of the filter element cover, and an inlet pipe and an outlet pipe are installed on the top cover, the inlet pipe transports the sewage into the filter element cover, and is filtered by the meltblown filter element and then drawn out through the outlet pipe to achieve sewage filtration. At the same time, meltblown filter elements are generally used in multiple groups, but in actual use, since the meltblown filter element adopts passive filtration, impurities tend to condense quickly on the surface of the meltblown filter element on the side of the water inlet, while the other side is not effectively utilized, or impurities condense in a part of the meltblown filter element, which also causes uneven use of the meltblown filter element, and then causes the meltblown filter element to be blocked, and then the filter element has to be replaced, resulting in a waste of resources. At the same time, since the filter elements are generally used in groups, it is impossible to quickly determine the specific location of the blocked filter element at one time, which makes the maintenance and replacement of the filter element inefficient.

[0039] In summary, the working principle of a melt-blown filter element that is easy to maintain provided by an embodiment of the present invention is: When the filter element body 1 is in use, water enters through the water inlet pipe 4, and the water inlet pipe 4 enters the filter element cover 2 through the impact water tank 601, and then is filtered by the filter element body 1, and then is pumped out through the water outlet pipe 5. During the water intake process, after the water enters the impact water tank 601, it enters the rotating water tank 609 through multiple water inlet holes 602 and multiple connecting holes 605, and then enters the rotating water distribution frame 603 through the connecting water pipe 610, and then is sprayed out through multiple water spray heads 604. The water impacts the multiple impact blades 607 to rotate continuously, so that the impact The shaft 606 rotates, and the impact shaft 606 rotates to drive the driving gear 608 to rotate, so that the driving gear 608 drives the driven ring gear 613 to rotate, and at this time the driven ring gear 613 drives the rotating water tank 609 to rotate, and then the rotating water tank 609 drives the rotating water distribution frame 603 to rotate through the connecting water pipe 610, and then the rotating water distribution frame 603 drives the multiple water spray heads 604 to rotate, and the incoming water is evenly sprayed on the filter element body 1, so that the filter element body 1 can fully and evenly filter the incoming water, avoiding the problem of uneven use of the filter element body 1; Furthermore, in the process of rotating the rotating water tank 609, the rotating frame 701 is driven to move, and the rotating frame 701 drives the lifting frame 702 to move, so that the lifting frame 702 drives the multiple cleaning brush heads 703 to rotate, and the cleaning brush heads 703 clean the surface of the filter element body 1 to avoid the condensation of impurities causing the blockage of the surface of the filter element body 1. At the same time, in the process of rotating the lifting frame 702, the extrusion frame 704 is driven to rotate, so that the extrusion frame 704 is squeezed downward by the extrusion head 705, and the rebound spring 706 is driven to be stressed. When the extrusion frame 704 is separated from the extrusion head 705, the rebound force of the rebound spring 706 makes the lifting frame 702 move upward to realize the vertical lifting of the lifting frame 702, and then the lifting frame 702 drives the multiple cleaning brush heads 703 to rotate and move up and down at the same time, thereby achieving the purpose of fully cleaning the filter element body 1; Furthermore, during the long-term use of the filter element body 1, the filter element body 1 or the filter element cover 2 is severely blocked, which reduces the water output of the water outlet pipe 5. At this time, the weight inside the filter element cover 2 decreases as a whole and cannot press down the compression sleeve 802. At this time, under the rebound force of the reset spring 810, the compression sleeve 802 rebounds, and the compression sleeve 802 drives the impact water tank 601 to rebound. At this time, multiple water inlet holes 602 in the impact water tank 601 are closed by the sealing plug 805, so as to block the water inlet to the filter element cover 2 and avoid leakage caused by continuous water supply. At the same time, the alarm head 807 extends out of the sealing sleeve 808. Since the filter elements are generally used in combination of multiple ones, the blockage problem of the filter element body 1 can be clearly known, which is convenient for maintenance and replacement.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
