DETAILED DESCRIPTION

[0031] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification.

[0032] As a specific embodiment, the circulating water powder filtering device of the first embodiment includes a housing 1 , a filter element 2 and a rotating power shaft 3 .

[0033] The housing 1 includes a housing bottom plate 13 and a drain port 19 is formed at the bottom. It is easy to understand that the housing 1 has an inner cavity and an opening at the top.

[0034] The filter element 2 includes a top frame 21, a filter element bottom plate 23, and a side filter screen 22 with filter holes (not shown in the drawings), and the two ends of the side filter screen 22 are respectively used for fixing the top frame 21 and the filter element bottom plate 23 to make the filter element 2 as a whole cylindrical. It is easy to understand that the top frame 21 is provided with a top frame opening 211, so the filter element 2 is also open at the top.

[0035] The side filter screen 22 is completely disposed in the housing 1 and a gap is provided between the side filter screen 22 and the inner wall of the housing 1 . It is easy to understand that the side filter screen 22 and the inner wall of the housing 1 are completely located in the housing 1 in the height direction.

[0036] The filter element 2 is vertically and detachably connected to the housing 1 for rotation. In other words, the axis of the rotational connection between the filter element 2 and the housing 1 is vertical, the top frame opening 211 of the filter element 2 is upward, and the housing bottom plate 13 is also horizontal accordingly.

[0037] The rotating power shaft 3 is directly or indirectly connected to the filter element 2, so that the filter element 2 can rotate. For example, the rotating power shaft 3 is the output shaft of the motor 39, the motor 39 is fixed to the bottom end surface of the housing bottom plate 13, and the rotating power shaft 3 passes through the housing bottom plate 13 and is detachably connected to the filter element bottom plate 23, so that the rotating power shaft 3 is connected to the filter element 2. Of course, the rotating power shaft 3 can also be directly connected to the filter element 2 by the method described later or other methods.

[0038] The working principle is that the dust-containing water discharged from the drain port 13 in CN210186665U passes through the top opening of the outer shell 1 and the top frame port 211 and enters the side filter 22 of the filter element 2. As the side filter 22 rotates, it passes through the side filter 22 and enters the gap between the inner wall of the outer shell and the side filter 22, thereby filtering the dust-containing water and converting it into filtered water. The filtered water is discharged from the drain port 19 into the circulating water pool.

[0039] When the equipment has been running for a while and the dust in the filter element 2 needs to be cleaned, the filter element 2 is separated from the outer shell 1 and moved upward, and the filter element 2 can be pulled out from the top opening of the outer shell 1. After that, the filter element 2 can be cleaned at the designated position by flushing with water or other methods.

[0040] It can be seen from the above that the circulating water dust filtering device of the first embodiment can filter dust and is also convenient for cleaning dust.

[0041] As one of the specific implementations, the filter element bottom plate 23 is fixedly provided with a connecting seat 231, and the housing bottom plate 13 is hinged with a rotating seat 131. For example, a rotating seat shaft 139 is fixedly provided at the bottom end of the rotating seat 131, and the housing bottom plate 13 is provided with a bearing seat 138. The rotating seat shaft 139 is embedded in the bearing seat 138 and connected with the bearing, so that the rotating seat 131 is hinged with the housing bottom plate 13; the rotating power shaft 3 is driven and connected with the rotating seat 131 so that the rotating seat 131 has a rotating power. One of the connecting seat 231 and the rotating seat 131 is a rotating groove 132 with an opening at the top, and the other is provided with a connecting protrusion 232 inserted into the rotating groove 132. The four connecting protrusions 232 are respectively embedded in the rotating grooves 132. Pulling out and inserting the connecting protrusion 232 into the rotating groove 132 can facilitate the disassembly and installation of the filter element 2. For example, the connecting protrusions 232 are multiple strip-shaped protrusions evenly arranged around the axis of the side filter screen 22. For example, there are four connecting protrusions 232, and the four connecting protrusions 232 are arranged in a cross as a whole, which can more conveniently achieve positioning when installing the filter element 2.

[0042] As one of the specific implementations, a shaft hole 233 is provided between the plurality of connecting protrusions 232, a convex shaft 133 embedded in the shaft hole 233 is provided at the top of the rotating seat 131, and the convex shaft 133 is coaxial with the rotating seat 131. This can ensure that the filter element 2 does not shake when rotating and improve the stability of the equipment.

[0043] As one of the specific embodiments, it also includes a top cover 4 provided with a top cover opening 41; the top cover 4 is movably connected to the top of the housing 1, such as being threaded and detachable or hinged and rotatable. When viewed from above, the top cover opening 41 is completely located in the top frame opening 211, so that dust-containing water can pass through the top cover opening 41 and the top frame opening 211 and enter the filter element 2. The top cover 4 is provided with a plurality of frame pressing wheels 42, which are respectively against or close to the top frame 21. It can ensure that the filter element 2 will not shake when rotating, and improve the stability of the equipment.

[0044] As one of the specific embodiments, it also includes a driving belt 31, and a driving belt opening 311 is opened on the side wall of the housing 1. For example, the driving belt 31 is a synchronous belt, a belt, etc. The driving belt 31 passes around the rotating seat 131 (for example, the rotating seat shaft 139 of the rotating seat 131) and the rotating power shaft 3. The driving belt 31 passes through the driving belt opening 311 so that the rotating power shaft 3 is located outside the housing 1. For example, the housing 1 is provided with a motor seat 18, and a motor 39 is fixedly provided on the motor seat 18, and the rotating power shaft 3 is the output shaft of the motor 39. The motor 39 does not need to be arranged at the bottom of the housing 1, which can realize the miniaturization of the equipment and facilitate the maintenance of the motor 39.

[0045] Second embodiment.

[0046] The circulating water filter device of the second embodiment further includes a fine-pore filter layer 24 having fine pores (not shown in the drawings), the pore diameter of the fine pores being smaller than the pore diameter of the filter hole, the fine-pore filter layer 24 being arranged on the filter element 2, and the water flow (the water flow containing dust or filtered water) can pass through the fine-pore filter layer 24. The filtering effect on the dust-containing water can be improved. For example, the fine-pore filter layer 24 is a 250-mesh filter.

[0047] As one of the specific implementations, the side filter screens 22 are two layers parallel to each other, the top frame 21 is detachably connected to the top of the side filter screens 22, and the fine-porous filter layer 24 is arranged between the side filter screens 22 and parallel to the side filter screens 22. It is easy to understand that the fine-porous filter layer 24 is cylindrical as a whole, which can improve the filtering effect of dust-containing water.
