Technical Field

[0001] This utility model relates to the field of recycling devices, and in particular to a multi-media filter forward wash drainage recycling device. Background Technology

[0002] The multi-media filter forward wash wastewater recovery device is a device that recovers and treats the wastewater after cleaning the media. With the changes in technology, people's requirements for multi-media filter forward wash wastewater recovery devices are also getting higher and higher.

[0003] Chinese Patent CN210993151U discloses a novel multi-media filter forward wash drainage recovery device, including a drainage recovery device pipe body. A filter exhaust device is installed on the upper outer surface of the drainage recovery device pipe body. An activated carbon adsorption layer and a HEPA layer are disposed inside the filter exhaust device, with the HEPA layer located on the upper outer surface of the activated carbon adsorption layer. A side inspection pipe is fixedly connected to one side of the drainage recovery device pipe body. This technical solution, with its disinfection spray pipe, filter exhaust device, and isolation net, can prevent the spread of bacteria and viruses in the water and prevent the discharge of polluted gases generated inside the device, thus avoiding environmental pollution. It also facilitates the cleaning of internal stains, offering better prospects for application.

[0004] However, the above technical solution has the following shortcomings: a large number of formed sludge blocks will remain in the wastewater after washing, and the bacteria in the sludge blocks will gradually be released during the wastewater recycling process, which will reduce the purification speed of the recycling device. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a multi-media filter forward wash drainage recovery device that uses a drive component to drive two dust collection components respectively, and the dust collection components capture the dirt inside the cleaning component and the cleaning half-cylinder b, thereby reducing the dirt content inside the liquid.

[0020] Example 1

[0021] like Figures 1-5 As shown, this embodiment proposes a multi-media filter forward wash drainage recovery device, including a drain pipe 1, a cleaning mechanism, a dust collection assembly 9, and a three-way pipe 8: the drain pipe 1 is connected to a directional valve 2, and the directional valve 2 is connected to two connecting pipes 3; the cleaning mechanism includes a cleaning assembly 5 connected to each of the two connecting pipes 3, a drive assembly 6 disposed on the two cleaning assemblies 5, and a cleaning half-cylinder b7 hinged to each of the two cleaning assemblies 5; the drive assembly 6 is drivenly connected to the two cleaning assemblies 5; one dust collection assembly 9 is placed on each of the two cleaning assemblies 5, and the dust collection assembly 9 includes a mounting post 91 connected to the cleaning assembly 5, a mesh frame 92 disposed circumferentially on the mounting post 91, and a rectangular block 93 disposed on the mounting post 91; the three-way pipe 8 is connected to the two cleaning assemblies 5.

[0022] In this embodiment, after cleaning the filter, the wastewater will flow sequentially through the drain pipe 1, the cleaning component 5, and the tee pipe 8. When the wastewater flows to the cleaning component 5, the drive component 6 will drive the mounting column 91 to rotate through the cleaning component 5. The mounting column 91 will drive multiple mesh bag frames 92 to rotate, capturing the dirt in the liquid into the mesh bag, thereby reducing the content of large particles in the liquid and improving the cleaning speed of subsequent wastewater.

[0023] Example 2

[0024] like Figure 1 , Figure 4 and Figure 5 As shown, this embodiment proposes a multi-media filter forward wash drainage recovery device. Compared with the first embodiment, in this embodiment, the cleaning component 5 includes a cleaning half-cylinder a51 connected to the connecting pipe 3, a bottom shaft 52 and a mounting rod rotatably disposed on the cleaning half-cylinder a51, a pulley 54 disposed on the mounting rod, an abutment cylinder 55 slidably disposed on the mounting rod, and springs 53 distributed at the mounting rod and abutting the abutment cylinder 55 and the cleaning half-cylinder a51; the mounting column 91 is connected to the abutment cylinder 55, the rectangular block 93 is connected to the bottom shaft 52, and a sealing gasket is provided between the cleaning half-cylinder a51 and the cleaning half-cylinder b7.

[0025] The cleaning half-cylinder a51 has a processing chamber 512 and two connecting holes 511 that are interconnected. The axes of the two connecting holes 511 do not intersect each other. After the liquid flows into the processing chamber 512 from the connecting hole 511, it will impact the cleaning half-cylinder a51 before flowing out to the other connecting hole 511. This increases the flow time of the liquid in the cleaning half-cylinder a51 and improves the capture effect of the dust collection component 9.

[0026] In this embodiment, the cleaning half-cylinder a51, together with the cleaning half-cylinder b7 and the sealing gasket, forms a sealed space processing cavity 512 distributed in the sealed space. The pulley 54 drives the abutment cylinder 55 to rotate synchronously under the drive of the drive assembly 6. Then, after the abutment cylinder 55 contacts the mounting post 91, the abutment cylinder 55, the mounting post 91 and the bottom shaft 52 abut against each other axially in sequence, driving the dust collection assembly 9 to rotate, which reduces the difficulty of disassembling the dust collection assembly 9.

[0027] Example 3

[0028] like Figures 1-3 As shown, this embodiment of the multi-media filter forward wash drainage recovery device, compared to Embodiment 1, includes a drive assembly 6 comprising a drive frame 61 mounted on two cleaning half-cylinders a51, a motor 62 mounted on the drive frame 61, a drive rod 63 mounted on the motor 62, two ratchet wheels 64 coaxially mounted on the drive rod 63, two drive pulleys 65 coaxially mounted on the drive frame 61, and an abutment ring 66 mounted on each of the two drive pulleys 65. The two ratchet wheels 64 abut against the two abutment rings 66 in a one-to-one correspondence, and a transmission belt is mounted on each of the two drive pulleys 65 and the two pulleys 54 in a one-to-one correspondence. The valve core of the directional valve 2 is a right-angle valve core.

[0029] In this embodiment, the motor 62 drives the drive rod 63 to rotate in both directions to push the two drive pulleys 65 to rotate. When the drive rod 63 rotates in the forward direction, one ratchet 64 abuts against the abutting ring 66, and the other ratchet 64 slides against the other abutting ring 66. This allows a single drive rod 63 to drive the pulley 54 to rotate by rotating in different directions. Both abutting rings 66 are rotatably equipped with abutting plates and return springs, which are used to switch between abutting and sliding contact.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
