Description

Technical Field

[0001] The utility model belongs to the technical field of multi-media filtering, in particular to a multi-media filtering device. Background Art

[0002] Multi-media filter is a process that uses two or more filter media to pass water with high turbidity through a certain thickness of granular or non-granular material under a certain pressure, thereby effectively removing suspended impurities and clarifying the water. Commonly used filter materials include quartz sand, anthracite, manganese sand, etc., which are mainly used for water treatment turbidity removal, softening water, pre-treatment of pure water, etc., and the turbidity of the outlet water can reach less than 3 degrees. In the process of filtering, the current multi-media filter is prone to clogging due to excessive impurities, and it is more troublesome to clean up the impurities after clogging.

[0003] The high throughput, low resistance, multi-media filter with publication number CN220633491U will compress the spring through the movable rod and movable plate. Through the cooperation of the spring and the damping block, the impact force can be offset to make the filter more stable and reduce the noise. The motor is regularly operated to drive the threaded rod to rotate, and the cleaning brush is driven downward through the threaded sleeve to clean the filter surface, reduce resistance, and increase the fluid flow channel. Through the cooperation of the anthracite filter plate and the quartz sand filter element, the filtering effect can be enhanced, and the advantages of buffering noise reduction, low resistance and multi-media are achieved. However, the convenience of its clogging and cleaning still has room for improvement. Utility Model Content

[0006] In a further embodiment, a water pump is installed on one side of the top of the top cover, and the suction and discharge ends of the water pump are respectively connected to external water and the interior of the first filter box.

[0007] In a further embodiment, the end of the lifting screw is rotatably connected to the inner wall of the collecting shell, and nut seats are symmetrically sleeved on both ends of the outer circumference of the lifting screw.

[0008] In a further embodiment, the bottom of the nut seat is fitted with the bottom of the impurity collecting shell, and a pulling rod is hinged between the top of the nut seat and the bottom of the lifting filter frame.

[0009] In a further embodiment, the two pulling rods are symmetrically distributed, and the end of one lifting screw is connected to a forward and reverse motor.

[0010] In a further embodiment, a discharge port is installed at the bottom center of the primary filter box, and a first connecting pipe is connected between the discharge port and the secondary filter housing.

[0011] In a further embodiment, a second connecting pipe is connected to one side of the secondary filter housing, and the other end of the second connecting pipe is in communication with the upper half of the collecting housing.

[0012] In a further embodiment, a one-way valve is installed at the connection point between the second connecting pipe and the impurity collecting shell, and the one-way valve allows water to be input into the impurity collecting shell in a one-way manner.

[0013] In a further embodiment, a collection cover for easy disassembly and assembly is fixed on the top of the collection shell.

[0014] In a further embodiment, a sealing plate is installed on one side of the lifting filter frame.

[0015] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0016] The design of the semi-arc filter plate can filter water. Through the rotation connection of the center rod and the design of multiple rotating filter plates on the periphery of the center rod, the water pump installed at the non-center position of the top cover outputs water at high pressure. Since the outlet of the water pump is on one side of the rotating filter plate, when the high-pressure water rushes to the rotating filter plate, it will drive the rotating filter plate to rotate and filter out through the semi-arc filter plate. The impurities will be transported by the rotating filter plate and enter the interior of the impurity collecting shell when passing through the side channel, so as to further collect the impurities and greatly reduce the occurrence of blockage.

[0017] The connection between the first connecting pipe and the secondary filter housing and the guidance of the second connecting pipe on one side of the secondary filter housing enable the impurities that cannot be filtered to be transported upward to the interior of the impurity collecting housing under pressure. Combined with the design of the one-way valve at the end of the second connecting pipe, the impurities in the water can only enter the impurity collecting housing, and the impurities and water in the impurity collecting housing cannot enter the second connecting pipe, so that backflow will not occur.

[0018] The rotating connection design of the lifting screw and the design of opposite thread directions at both ends of the outer periphery of the lifting screw, the symmetrical sleeve arrangement of the nut seats at both ends of the lifting screw and the hinged design of the pull rod, in conjunction with the connection between the forward and reverse motors and the lifting screw, can further drive the nut seats and the pull rods to move synchronously when the forward and reverse motors are running, further driving the lifting filter frame to rise, and then opening the impurity collecting cover, the internal impurities can be easily cleaned, and at the same time, when it rises to the cleaning position, the blocking plate will block the side passage, so that the filtration does not need to be stopped during the cleaning process, which helps to improve the filtration efficiency;

[0019] The multi-media filtering device can not only pre-filter the water and collect the impurities in a centralized manner, but also does not need to stop the filtering process during the impurity cleaning process, thereby greatly improving the filtering efficiency.

[0030] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0031] See also Figures 1 to 4 The general structure of the device body includes a primary filter box 1, a top cover 2, and a secondary filter shell 4. The top of the primary filter box 1 is open and fixed with the top cover 2. The four corners of the bottom of the primary filter box 1 are connected with supporting feet. A water pump 12 is installed on one side of the top of the top cover 2. The suction end of the water pump 12 is connected with the external water liquid, and the discharge end of the water pump 12 is connected with the interior of the primary filter box 1. When the water pump 12 inputs water liquid, high-strength pressure will be generated at the same time. Filter material 5 is arranged inside the primary filter box 1 and the secondary filter shell 4. The filter material 5 can be quartz sand, anthracite, manganese sand, etc. A discharge port 3 is installed at the bottom center of the primary filter box 1. A first connecting pipe 6 is connected between the discharge port 3 and the secondary filter shell 4, and an outlet is provided on the secondary filter shell 4 away from the connecting side.

[0032] See also Figures 1 to 3 In order to reduce clogging, a semi-arc filter plate 13 is installed at the inner center of the first filter box 1. The semi-arc filter plate 13 is in a semi-arc shape. The upper half of the inner circumference of the first filter box 1 is rotatably connected to a center rod 14. The outer four sides of the center rod 14 are all connected to rotating filter plates 15. The rotating side of the rotating filter plate 15 can fit with the semi-arc filter plate 13.

[0033] The water pump 12 is located on one side of the rotating filter plate 15 . When the water pump 12 is running, the water can impact the rotating filter plate 15 , further rotating the rotating filter plate 15 , and scraping the impurities again to prevent the impurities from being blocked on the semi-arc filter plate 13 .

[0034] See also Figure 1 , Figure 2 and Figure 4In order to realize centralized collection, a collection shell 8 is provided on one side of the upper half of the primary filter box 1. The center of one side of the collection shell 8 is connected to the primary filter box 1 through a side passage 7. A lifting filter frame 9 is provided on the lower half of the inner circumference of the collection shell 8. A liquid guide pipe 11 is connected between the bottom of the collection shell 8 and the primary filter box 1. After being filtered by the lifting filter frame 9, the liquid can be transported to the interior of the primary filter box 1. The lifting filter frame 9 has the same filtering mesh as the semi-arc filter plate 13.

[0035] In order to achieve non-stop cleaning, a blocking plate 18 is installed on the side of the lifting filter frame 9 close to the side passage 7. The blocking plate 18 is adapted to the side passage 7 and can be fitted. After fitting, the side passage 7 can be blocked to achieve closure.

[0036] In order to achieve lifting, a lifting screw 21 is provided at the lower half of the inner circumference of the collecting shell 8, and the end of the lifting screw 21 is rotatably connected to the inner wall of the collecting shell 8 through a bearing. A forward and reverse motor 24 is installed on one side of the collecting shell 8. The driving end of the forward and reverse motor 24 passes through the collecting shell 8 and is connected to the end of the lifting screw 21. A collecting cover 16 for easy disassembly is fixed on the top of the collecting shell 8;

[0037] The two ends of the outer periphery of the lifting screw 21 are provided with threads in opposite directions, and the two ends of the outer periphery of the lifting screw 21 are sleeved with nut seats 22, one side of the nut seat 22 is in contact with the inner wall of the impurity collecting shell 8, thereby achieving position limiting, and a pull rod 23 is hinged between the top of the nut seat 22 and the lifting filter frame 9, and the two pull rods 23 are symmetrically distributed;

[0038] Since the length of the pull rod 23 is fixed, combined with the vertical distance between the pull rod 23 and the lifting filter frame 9 and the lifting screw 21, a triangle is formed. Since the two pull rods 23 are symmetrically distributed, it is equivalent to having two equal triangular stable structures at both ends. Therefore, when displacement occurs, regular movement will occur and no tilting will occur.

[0039] See also Figure 1 and Figure 2 In order to achieve secondary anti-clogging, a second connecting pipe 10 is connected to one side of the secondary filter housing 4, and the other end of the second connecting pipe 10 is connected to the upper half of the impurity collecting housing 8. A one-way valve 17 is installed at the connection between the second connecting pipe 10 and the impurity collecting housing 8. The one-way valve 17 allows water to be input into the impurity collecting housing 8 in one direction.

[0040] The above-mentioned components and electrical equipment are all existing technologies or existing feasible technologies. The working principles, sizes and models are irrelevant to the functions of this application, so they are not described in detail, and they are all controlled by remote control switches.

[0041] How it works

[0042] When the multi-media filter device is needed, water is input into the primary filter box 1 through the water pump 12. When the water is input at high pressure, the rotating filter plate 15 is impacted and rotated, and the filtered water passes through the semi-arc filter plate 13 and is then filtered by the filter material 5.

[0043] The impurities are transported by the rotating filter plate 15, and when passing through the side passage 7, they are sent to the interior of the impurity collecting housing 8 and fall into the interior of the lifting filter frame 9 to be collected by the impurities.

[0044] When the filtered water is filtered again by the filter housing 4 for secondary filtration, when the residual impurities are retained, they will pass through the second pipe 10 and the one-way valve 17 under high pressure, and then be transported to the interior of the collection housing 8 to further realize secondary collection. Thus, the reciprocating filtration can be realized while greatly reducing the occurrence of blockage.

[0045] When it is necessary to clean the impurities, close the one-way valve 17 to achieve sealing, start the forward and reverse motor 24, drive the lifting screw 21 to rotate, make the nut seat 22 move synchronously, make the pulling rod 23 move synchronously, make the lifting filter frame 9 rise to the required height, and at the same time, the sealing plate 18 will close the side passage 7, and then open the impurity collecting cover 16 to clean the impurities.
