Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a graded filtering treatment device. Background Art

[0002] Filtration is the process of purifying a fluid through a special device. There are many ways to filter, and a wide range of materials are used. Solid-liquid, solid-gas, large particles, and small particles are all very common. Filtration is an operation in which the liquid (or gas) in a suspension (or a hot gas containing solid particles) passes through a medium under the action of a driving force or other external force, and solid particles and other substances are retained by the filter medium, thereby separating the solids and other substances from the liquid (or gas). Before preparing ultrapure water, the water to be used needs to be filtered. In order to improve the filtration effect and efficiency, a graded filter is usually used to filter the water. However, the traditional multi-stage filtration device does not have a filter cleaning mechanism. During long-term filtration, a large amount of impurities will be filtered out of the filter screen inside the filter. These impurities will cause the filter screen to be blocked, affecting the filtration of the water. Utility Model Content

A water retaining ring 7 is fixedly installed in the middle of the tops of the three filter plates 6. A cleaning mechanism 5 is installed in the housing 1. Water can enter the housing 1 through the water inlet pipe 3. The water is filtered in multiple stages through the three filter plates 6 with successively decreasing mesh holes to remove impurities of different particle sizes in the water and improve the purity of the water.

[0017] The cleaning mechanism 5 includes a rotating shaft 51, a collecting frame 52, a rotating frame 53, a slot 54, a motor 55 and an intercepting net 56. The motor 55 is fixedly installed in the middle of the bottom of the shell 1. The output shaft of the motor 55 passes through the through hole at the bottom of the shell 1 and is fixedly connected to the lower end of the rotating shaft 51. A sedimentation barrel 8 is fixedly installed on the top of the shell 1. The upper end of the sedimentation barrel 8 is hollow. The sedimentation barrel 8 is located on the lower side of the water inlet on the shell 1. The middle part of the bottom of the sedimentation barrel 8 is rotatably connected to the top of the rotating shaft 51. When water enters the shell 1, the sedimentation barrel 8 can be used to precipitate heavier impurities to prevent the heavy impurities from impacting the filter plate 6 and damaging the filter plate 6. Six rotating frames 53 are fixedly installed on the side of the rotating shaft 51, and the bottoms of the six rotating frames 53 are respectively in contact with the tops of the three filter plates 6. The bottom of the rotating frame 53 facing the rotation direction is provided with an inclined surface, and three annular support grooves 9 are provided on the inner wall of the shell 1. Support blocks 10 are fixedly installed on the side of one end of the outer side of the six rotating frames 53. The six support blocks 10 are respectively slidably installed in the three support grooves 9. The support grooves 9 and the support blocks 10 cooperate to provide support for one end of the outer side of the rotating frame 53, thereby improving the stability of the rotating frame 53 during rotation. Slots 54 are provided on the bottom and top of each rotating frame 53, and each slot The collecting frame 52 is inserted into each of the two collecting frames 54.

A positioning hole 13 matching the two positioning rods 12 is opened at the top of the rotating frame 53. The collecting frame 52 can be positioned by the positioning rods 12 on the fixing plate 11 and the positioning holes 13 on the rotating frame 53 to prevent it from shaking.

The motor 55 is electrically connected to the switch 2. While filtering, the motor 55 can drive the rotating shaft 51 to rotate, so that the rotating shaft 51 drives the rotating frame 53 to rotate, so that the water and impurities on the filter plate 6 enter the rotating frame 53 and the collecting frame 52. As the rotating frame 53 rotates, the water passes through the intercepting net 56 and flows downward from the mesh on the filter plate 6, so that the impurities can be intercepted by the intercepting net 56 and retained in the collecting frame 52, thereby realizing the cleaning of the filter plate 6, preventing the filter plate 6 from being blocked, and improving the filtering efficiency of water.

[0018] The working principle of the utility model is as follows: the external power supply is turned on, the water inlet pipe 3 is connected to the external water supply pipe, and water enters the housing 1 from the water inlet pipe 3. At this time, the water will first enter the sedimentation barrel 8. At this time, the heavier impurities in the water, such as gravel and sand, will sink to the bottom of the sedimentation barrel 8. As the liquid level in the sedimentation barrel 8 rises, the water will flow out from the hollow position at the upper end of the sedimentation barrel 8 to the filter plate 6. The water is filtered in three stages through the meshes that decrease from top to bottom on the three filter plates 6. During the filtration, impurities in the water that are larger than the mesh diameter of the filter plate 6 will remain on the filter plate 6. The motor 55 is controlled to work by the switch 2, so that the output shaft of the motor 55 drives the rotating shaft 51 to rotate, and the rotating shaft 51 drives the rotating frame 53 to rotate. When the rotating frame 53 rotates, the water and impurities on the filter plate 6 will be filtered. The impurities on the filter plate 6 can be collected in the collecting frame 52 to prevent the impurities from clogging the mesh holes on the filter plate 6 and affecting the filtration of water. After the filtration is completed, the water baffle 16 can be pushed to move to the inside of the shell 1 to open the cleaning slot 15, hold the handle bar 14, and pull the collecting frame 52 out of the slot 54 in the rotating frame 53, and take the impurities cleaned in the collecting frame 52 out of the shell 1 for cleaning.
