Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a multi-media filter. Background Technology

[0002] Multi-media filters utilize 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 media include quartz sand, anthracite, and manganese sand. They are mainly used for water treatment, turbidity removal, water softening, and pretreatment of pure water.

[0003] Currently, multi-media filters rely on a single filtration method during operation, which fails to improve filtration efficiency. After prolonged use, they adsorb a large amount of impurities, reducing their effectiveness in filtering wastewater. However, most current filters are one-piece cylindrical structures, making internal cleaning inconvenient and resulting in prolonged downtime. These issues require improvement. Utility Model Content

[0004] The purpose of this invention is to solve the problem of insufficient filtration effect in the existing technology, and to propose a multi-media filter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-media filter, comprising a cylinder, a cylinder cover, a flange ring, a water inlet, a discharge outlet, a support leg, and a filter assembly. The cylinder cover is disposed on the upper surface of the cylinder, and the flange ring is fixedly connected to the surfaces of the cylinder and the cylinder cover. The water inlet is disposed at the top of the cylinder cover, and the discharge outlet is disposed on the lower surface of the cylinder. The support leg is fixedly connected to the lower surface of the cylinder. The filter assembly is disposed inside the cylinder, and the filter assembly includes a filter groove, which is slidably connected to the inner wall of the cylinder. The filter groove is provided in two sets, and the surface of the filter groove is provided with uniformly arranged permeable holes. A connecting rod is fixedly connected to the inner wall of the cylinder cover, and a water collection tray is fixedly connected to the other end of the connecting rod.

[0006] Furthermore, the filter tank is equipped with a filter medium, and the connecting rods are provided in three sets, which are evenly arranged in a circle.

[0007] Furthermore, a cleaning component is provided inside the cylinder, the cleaning component including a mounting bracket, the mounting bracket being fixedly connected to the lower surface of the cylinder, and a motor being installed inside the mounting bracket.

[0008] Furthermore, a threaded rod is fixedly connected to the output end of the motor, the threaded rod is rotatably connected to the inner wall of the cylinder, and a lifting plate is threadedly connected to the surface of the threaded rod.

[0009] Furthermore, the filter tank is disposed on the upper surface of the lifting plate, and the lifting plate is slidably connected to the inner wall of the cylinder.

[0010] Furthermore, the bottom of the cylinder is provided with a water outlet, the surface of the discharge port is provided with a sliding groove, the inner wall of the sliding groove is slidably connected with a blocking cover, and the inner wall of the sliding groove is slidably connected with a stop block, which abuts against the blocking cover.

[0011] Furthermore, the inner wall of the discharge port is slidably connected with a bolt, the bolt is slidably connected to the inner wall of the abutment, and the surface of the bolt is threaded with a nut.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, a filter assembly is installed to facilitate multi-stage filtration. First, filter media is filled into the cylinder, and then the cylinder cover is fixed and sealed to the cylinder body using a flange. Next, wastewater is injected into the cylinder through the inlet. Under the guidance of the collection tray, the wastewater flows towards the added filter media. At this point, the wastewater splits into two paths: one flows downwards and is continuously filtered by the added media, while the other flows into the filter tank, where it is further filtered by the media and then flows into the second filter tank through the bottom permeable holes. The continuously flowing wastewater eventually reaches the bottom filter tank, and finally, the clean water, completely filtered by the bottom filter tank, exits from the outlet. The filter media is discharged from the discharge port. When cleaning the inner cavity of the cylinder, simply loosen the bolts and remove the abutment and the stop cover. Then, start the motor, which drives the threaded rod to rotate. The threaded rod pushes the lifting plate upward. Since the lifting plate is unrestrained, it will rotate and rise simultaneously, cleaning the inner wall of the cylinder while simultaneously pushing the filter tank upward, making it easy to remove the filter tank for cleaning. By setting up the filter components, multi-stage filtration is facilitated, improving the filtration effect. It also reduces the time spent cleaning the inner wall of the filter and the downtime of the filter, thus effectively improving the practicality of the equipment. Attached Figure Description

[0021] The following section will explain the specific settings and functions of its filter component 7.

[0022] In this embodiment: the filter assembly 7 includes a filter tank 71, which is slidably connected to the inner wall of the cylinder 1. The filter tank 71 is provided in two sets, and the surface of the filter tank 71 is provided with uniformly arranged water-permeable holes 72. The inner wall of the cylinder cover 2 is fixedly connected to a connecting rod 73, and the other end of the connecting rod 73 is fixedly connected to a water collection tray 74.

[0023] The effects achieved by the above components are as follows: the water collection tray 74 is set so that sewage can flow to the filter tank 71; water permeable holes 72 are opened on the surface of the filter tank 71 to complete the diversion of sewage; the filtration effect of the media inside the two sets of filter tanks 71 is different.

[0024] Specifically, the filter tank 71 is equipped with a filter medium, and there are three sets of connecting rods 73, which are evenly arranged in a circle.

[0025] The effect achieved by the above components is: to install the connecting rod 73 and the water collection tray 74.

[0026] Specifically, a cleaning component 75 is provided inside the cylinder 1. The cleaning component 75 includes a mounting bracket 751, which is fixedly connected to the lower surface of the cylinder 1. A motor 752 is installed inside the mounting bracket 751.

[0027] The effect achieved by the above components is: to install the motor 752 by setting up the mounting bracket 751.

[0028] Specifically, the output end of the motor 752 is fixedly connected to a threaded rod 753, the threaded rod 753 is rotatably connected to the inner wall of the cylinder 1, and a lifting plate 754 is threadedly connected to the surface of the threaded rod 753.

[0029] The effect achieved by the above components is that the threaded rod 753 can push the lifting plate 754 to clean the inner wall of the cylinder 1.

[0030] Specifically, the filter tank 71 is set on the upper surface of the lifting plate 754, and the lifting plate 754 is slidably connected to the inner wall of the cylinder 1.

[0031] Specifically, the bottom of the cylinder 1 is provided with a water outlet 8, the surface of the discharge port 5 is provided with a sliding groove 76, the inner wall of the sliding groove 76 is slidably connected with a blocking cover 77, and the inner wall of the sliding groove 76 is slidably connected with a stop block 78, which abuts against the blocking cover 77.

[0032] The effect achieved by the above components is: the blocking cover 77 facilitates the discharge of the filter medium.

[0033] Specifically, the inner wall of the discharge port 5 is slidably connected with a bolt 79, which is slidably connected to the inner wall of the abutment block 78, and the surface of the bolt 79 is threaded with a nut 710.

[0034] The effect achieved by the above components is that the bolts 79 and nuts 710 can fix the abutment 78.

[0035] Working principle: By setting up the filter assembly 7, multi-stage filtration is facilitated. First, filter media is filled into the cylinder 1, and then the cylinder cover 2 is fixed and sealed to the cylinder 1 through the flange. Next, sewage is injected into the cylinder 1 through the inlet 4. Under the guidance of the collection plate 74, the sewage flows to the added filter media. At this time, the sewage splits into two paths: one path flows downward and is continuously filtered by the added media, and the other path flows to the filter tank 71, where it is filtered by the media and then flows into the second filter tank 71 through the bottom permeable hole 72. The continuously downward sewage eventually flows to the bottom of the filter tank. The water that has been completely filtered by the bottom filter tank 71 is discharged from the outlet 8 of the cylinder 1. When cleaning the inner cavity of the cylinder 1, simply loosen the bolt 79, remove the abutment 78 and the blocking cover 77, and the filter medium will be discharged from the discharge port 5. Then start the motor 752, which drives the threaded rod 753 to rotate. The threaded rod 753 pushes the lifting plate 754 upward. Since the lifting plate 754 is unrestrained, it will rotate and rise at the same time, simultaneously pushing the filter tank 71 upward while cleaning the inner wall of the cylinder 1, making it easy to remove the filter tank 71 for cleaning.

[0036] By setting up filter component 7, multi-stage filtration is facilitated, improving the filtration effect. It also reduces the time spent cleaning the inner wall of the filter and the downtime of the filter, thus effectively improving the practicality of the equipment.
