Technical Field
The invention relates to a filtering device with a self-cleaning function.
Background
The filtering equipment plays a role in ensuring normal operation of the lubricating oil system, and the traditional filter needs to be replaced, cleaned or scraped by operators frequently, so that the labor intensity of the operators is increased, and the overall proposed automation requirement is difficult to meet. The self-cleaning filter is widely applied to the advantages of high automation degree, no shutdown operation, long maintenance period, less filter element spare parts, low labor intensity of operators and the like.
The self-cleaning filter can automatically remove the pollutant trapped on the filter element by utilizing certain conditions (such as filtered clean liquid, compressed air and the like) and restore the filter channel of the filter element. Self-cleaning filters belong to today's more sophisticated filtration equipment.
The existing products mainly comprise a circular shaft suction nozzle type liquid self-cleaning filter and a rotary arm type liquid self-cleaning filter. The first two self-cleaning filters need more self-cleaning flow and the pressure fluctuation of subsequent equipment is large due to non-uniform self-cleaning liquid flow, so the first two self-cleaning filters are rarely used in an oil system; the compressed air type self-cleaning filter is easy to bring algae and silt, is uneven in cleaning, complex in structure, more in potential fault points and leakage points, poor in reliability and maintainability and poor in practical application effect.

Advantageous effects
Compared with the prior art, the invention has the following advantages.
1. The wave folds of the star-shaped structure are in one-to-one correspondence with the inner skeleton hole rows, so that each wave fold section of the star shape can form an independent self-cleaning cavity after being butted with the dirt absorbing port, and in the self-cleaning process, besides the wave fold sections of the filter element covered by the rectangular dirt absorbing port on the lip edge of the sucking disc are subjected to self-cleaning, the rest wave fold sections of the filter element still carry out uninterrupted filtration, and the flow required by self-cleaning is smaller because the wave fold area participating in self-cleaning is smaller each time.
2. The sucker assembly adopts a split structure, and the sucker is tightly attached to the inner surface of the inner framework of the self-cleaning filter element under the action of the compression spring, so that the bypass fluid between the sucker and the inner surface gap of the inner framework during self-cleaning is reduced, and the self-cleaning flow is further reduced to be small;
3. the sucker of the sucker assembly is provided with the lip edge, and the width of the lip edge is increased, so that the self-cleaning flow is further reduced;
4. when the sucking disc is adopted for self-cleaning, the self-cleaning flow of the hole row of the sucking disc, which is opposite to the inner framework, is maximum, and the self-cleaning flow of the hole row of the sucking disc, which is opposite to the inner framework, is minimum; when the upper sucker of the sucker assembly is opposite to the hole row of the inner framework at the upper part of the self-cleaning filter element, the lower sucker is opposite to the hole row of the inner framework at the lower part of the self-cleaning filter element, and the flow is more uniform during self-cleaning by adopting a peak shifting and valley filling method;
5. the invention integrates the prefilter filter element in the equipment, has compact structure, has lower filtering precision than the self-cleaning filter element, and effectively protects the sucker component and the self-cleaning filter element.
