Specific implementation

[0022] The utility model discloses an auxiliary cleaning mechanism three-dimensional structure schematic diagram for the utility model

[0023] Specific implementation time: as Figures 1-5 The utility model discloses a rotatable piece of corrosion -resistant sea water filter, including rotation axis 1: the outside of rotation axis 1 is provided with positioning installation mechanism 2, and the side of positioning installation mechanism 2 is provided with portable assembly mechanism 3, and the side of portable assembly mechanism 3 is provided with auxiliary cleaning mechanism 4, and positioning installation mechanism 2 includes positioning ring 21 and rotating piece body 22, and the outside of rotation axis 1 is provided with positioning ring 21 at equal intervals, and the lateral outer wall of positioning ring 21 is provided with rotating piece body 22 at equal intervals, and rotating piece body 22 is provided as the oblique plate structure, and two sets of rotating piece body 22 are symmetrically distributed on the side of positioning ring 21, positioning ring 21 is provided here and is positioned to the effect of installing rotating piece body 22, and the setting of rotating piece body 22 is accelerated the flow rate of water flow through the rotational flow force generated when it rotates, to accelerate the effect of filtering on the basis of accelerating water flow through filter, and simultaneously, rotating piece body 22 is provided as the oblique plate structure, so that its contact area with water flow is larger when rotating, so that water flow can be better pushed to flow.

[0024] Portable assembly mechanism 3 includes positioning groove 31 and nut block 32, and the lateral outer wall of positioning ring 21 is provided with positioning groove 31, and positioning groove 31 is provided with two, and one of positioning groove 31 is provided with nut block 32 and is installed in the side inner wall embedding mode, and the lateral outer wall of rotation axis 1 is provided with symmetrical thread groove 33, and nut block 32 and thread groove 33 are all screwed with positioning bolt 34 between; reference Figure 1As shown, the positioning ring 21 and the rotating piece body 22 are arranged at equal intervals in four groups. Since the rotating piece bodies 22 at the front end and the rear end are subjected to greater resistance, the two groups of rotating piece bodies 22 are arranged in an assembled manner for timely replacement, while the two groups of rotating piece bodies 22 in the middle play an auxiliary transmission effect and are not easy to damage, so they are welded to the outside of the rotating shaft 1. When the rotating piece body 22 at the front end of the rotating shaft 1 needs to be replaced due to severe wear, the positioning bolt 34 is simply unscrewed from the inside of the positioning groove 31, the positioning ring 21 changes from a locked state to a movable state, and then the rotating piece body 22 is directly taken out together with the positioning ring 21 from the outside of the rotating shaft 1. When installing a new rotating piece body 22, the positioning ring 21 is first sleeved onto the outside of the rotating shaft 1, then the positioning groove 31 on the side of the positioning ring 21 is adjusted to overlap the corresponding threaded groove 33, and after adjustment, the positioning bolt 34 is screwed through the positioning groove 31 and the threaded groove 33 and the nut block 32 to complete the installation.

[0025] The auxiliary cleaning mechanism 4 includes a support column 41, a cylindrical groove 42, and a piston rod 43. The support column 41 is arranged at equal angles on the side outer wall of the rotating shaft 1. The support column 41 is provided with a cylindrical groove 42 away from the inside of the shaft body of the rotating shaft 1. The piston rod 43 is slidably installed in the inside of the cylindrical groove 42. The piston rod 43 and the bottom inner wall of the cylindrical groove 42 are connected by a contact spring 44. The extending end of the piston rod 43 is arranged outside the cylindrical groove 42, and the extending end of the piston rod 43 is connected with the side outer wall of the limiting scraper 45. When the rotating shaft 1 rotates in actual use, the support column 41 also rotates synchronously. Since the contact spring 44 connects and limits the support column 41 and the piston rod 43, the support column 41 also drives the piston rod 43 to rotate when it rotates. Then, the rotation of the piston rod 43 automatically drives the limiting scraper 45 to rotate. When the limiting scraper 45 rotates, it automatically cleans the inner wall of the filter cylinder in the filter, thereby reducing the amount of solid impurities adhering to the inner wall of the filter cylinder. The arrangement of the contact spring 44 ensures that the limiting scraper 45 can always maintain a transmission state of adhering to the inner wall of the filter cylinder even if it is worn out, thereby ensuring the cleaning effect of the limiting scraper 45.

[0026] The limiting scraper 45 is arranged as an inclined plate structure, and the side outer wall of the limiting scraper 45 away from the rotating shaft 1 is arranged as an arc-shaped structure. Through the guiding action of the limiting scraper 45, the solid impurity particles on the inner wall of the filter cylinder can be well guided to the bottom end of the device. At the same time, the side outer wall of the limiting scraper 45 close to the filter cylinder is arranged as an arc-shaped structure, which can better clean the inner wall of the filter cylinder and has smaller transmission resistance.

[0027] The positioning ring 21 and the piston rod 43 are staggered and arranged at equal intervals on the outside of the rotating shaft 1. This design ensures the normal working effect of the two without interference.

[0028] The positioning ring 21 is arranged at the position of the rotating piece body 22, and the rotating piece body 22 is arranged to accelerate the flow rate of the water flow through the rotational flow generated when the rotating piece body 22 rotates, thereby achieving the effect of accelerating the filtration on the basis of accelerating the water flow through the filter, and the rotating piece body 22 is arranged as an inclined plate structure, so that the contact area with the water flow is larger when rotating, thereby better promoting the flow of the water flow.

[0029] Reference Description Figure 1 As shown in the figure, the positioning ring 21 and the rotating piece body 22 are arranged at equal intervals, and four groups are arranged. Since the front end and the rear end of the rotating piece body 22 are blocked, the two groups of rotating piece bodies 22 are arranged in an assembled manner and can be replaced in time, and the middle two groups of rotating piece bodies 22 have the effect of auxiliary transmission and are not easy to damage, so they are welded and installed outside the rotating shaft 1. When the rotating piece body 22 at the front end of the rotating shaft 1 needs to be replaced due to severe wear, the positioning bolt 34 is completely screwed out from the inside of the positioning groove 31, and the positioning ring 21 changes from the locked state to the active state. Then the rotating piece body 22 is taken out together with the positioning ring 21 from the outside of the rotating shaft 1. When installing a new rotating piece body 22, the positioning ring 21 needs to be sleeved on the outside of the rotating shaft 1 first, and then the positioning groove 31 on the side of the positioning ring 21 is adjusted to coincide with the corresponding position of the threaded groove 33. After adjustment, the positioning bolt 34 is screwed through the positioning groove 31 and the threaded groove 33 and the nut block 32 to complete the installation.

[0030] When the rotating shaft 1 rotates in actual use, the support column 41 will also rotate synchronously. Here, the support column 41 is connected and limited with the piston rod 43 by the abutting spring 44, so that the support column 41 will also drive the piston rod 43 to rotate when rotating. Then the rotation of the piston rod 43 will automatically drive the limiting scraper 45 to rotate, which will automatically clean the inner wall of the filter cylinder inside the filter, thereby reducing the adhesion of solid impurities on the inner wall of the filter cylinder. The arrangement of the abutting spring 44 enables the limiting scraper 45 to always maintain the transmission state of being attached to the inner wall of the filter cylinder even if it is worn, thereby ensuring the cleaning effect of the limiting scraper 45.

[0031] The specific filter how to drive the rotating shaft 1 to rotate and the specific installation method can be assembled according to the existing conventional technical means. Meanwhile, the rotating piece body 22 is recommended to be made of stainless steel or titanium alloy and other corrosion-resistant materials, so that the device has good seawater corrosion resistance. All belong to existing conventional operation technical means, which will not be described in detail here.

[0032] Furthermore, it should be understood that although the specification is described in terms of embodiments, not every embodiment includes every feature or implementation described herein. The specification can include implicit combinations of explicitly mentioned features and / or implicit combinations of implicitly mentioned features. Such combinations are also expressly included within the scope of the specification and an embodiment.
