Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an automatic cleaning device for a fiber disc filter tank. Background Technology

[0002] The automatic cleaning device for fiber disc filter tanks is a new type of wastewater treatment equipment. Its core structure, the fiber disc, consists of two layers: a filter cloth and a fiber mesh. Wastewater first passes through the filter cloth and then comes into contact with and is filtered by the fiber mesh, thus achieving the filtration of wastewater. After the fiber disc filter tank has been treating wastewater for a period of time, a large amount of impurities will adhere to the outer side of the filter cloth and fiber mesh, affecting the filtration effect. Therefore, it is necessary to backwash the filter disc. Usually, a suction cup is installed in the filter tank and pressed against the outer surface of the filter disc. When the filter disc and the suction cup rotate relative to each other, the suction cup is used to suck out the impurities from the outer surface of the filter disc. However, the filter cloth will wear out to varying degrees after prolonged use and repeated backwashing. Since the suction cups are usually fixedly installed on the inner wall of the filter tank, gaps will appear between the filter disc and the suction cup when the filter cloth is worn, affecting the suction effect of the suction cup and thus affecting the cleaning rate of the outer surface of the filter disc. In addition, the existing fiber disc filter tank has a one-piece structure for the disc assembly. When the fiber filter cloth on the surface of the disc assembly needs to be replaced, it is inconvenient to remove the fiber filter cloth from the disc assembly, and the removal efficiency is low. At the same time, a lot of dust will accumulate at the bottom of the filter tank.

[0003] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The reference provided by this utility model Figures 1 to 4 :

[0026] For ease of description, the rotation direction of the turntable assembly 32 (which will be described in detail below) is defined as forward, and the reverse is backward.

[0027] An automatic cleaning device for a fiber disc filter includes a filter tank 1 and a clear water tank 2 disposed beside the filter tank 1. A connection port 21 is provided between the clear water tank 2 and the filter tank 1. An inlet pipe 11 is fixed to the side of the filter tank 1 away from the clear water tank 2, and an outlet pipe 22 is connected to the end of the clear water tank 2 away from the filter tank 1. Preferably, an inlet weir 12 is provided in the filter tank 1 near the inlet pipe 11, and an outlet weir 23 is provided in the clear water tank 2 near the outlet pipe 22.

[0028] The filter tank 1 is equipped with a filtration device, which includes a rotating shaft 31 rotatably installed inside the filter tank 1 and several rotating disk assemblies 32 evenly distributed on the rotating shaft 31. The rotating shaft 31 is located near the connecting port 21 in the filter tank 1. The rotating shaft 31 is connected to the clear water tank 2 through the connecting port 21. Wastewater enters the filter tank 1 through the inlet pipe 11, is filtered by several fiber filter cloths (which will be described in detail below) on the rotating disk assembly 32, enters the rotating shaft 31, flows to the connecting port 21, and then flows out through the outlet pipe 22 in the clear water tank 2.

[0029] Specifically, each turntable assembly 32 includes multiple sector-shaped frame plates and a fiber filter cloth covering the outer surface of the sector-shaped frame plates. Each sector-shaped frame plate has a tube (not shown in the figure) fixed on the side near the rotating shaft 31. The side wall of the rotating shaft 31 has a socket (not shown in the figure) for inserting the tube. The sector-shaped frame plates are detachably connected to the socket of the rotating shaft 31 through the tube. When installing the sector-shaped frame plates, the tube is first inserted into the socket, so that the inside of the sector-shaped frame plate is connected to the inside of the rotating shaft 31 through the tube. Water filtered by the fiber filter cloth can then enter the inside of the rotating shaft 31 along the tube.

[0030] Furthermore, a drive device for rotating the shaft 31 is provided at the top of the filter tank 1. The drive device includes a motor 41 and a driven sprocket 42 wound around the surface of the shaft 31.

At least one second connecting pipe 53 and at least one third connecting pipe 54 are arranged vertically on the first connecting pipe 52. Scrapers 55 are arranged on the second connecting pipe 53 facing the two rotating disc assemblies 32. Cleaning brushes 56 are arranged on the third connecting pipe 54 facing the two rotating disc assemblies 32. The scrapers 55 are arranged at the rear end of the cleaning brushes 56. The scrapers 55 and the cleaning brushes 56 abut against the fiber filter cloth for cleaning the fiber filter cloth.

[0032] Furthermore, the cleaning device 5 also includes a cleaning pump 57 located outside the filter tank 1. The cleaning pipe 51 is provided with a first through hole 521 at the connection point of each first connecting pipe 52, the second connecting pipe 53 is provided with a second through hole 531 at the connection point of the scraper 55, and the third connecting pipe 54 is provided with a third through hole 541 at the connection point of the cleaning brush 56. The cleaning pipe 51, the first through hole 521, the second through hole 531 and the third through hole 541 are all connected, and the cleaning pipe 51 is connected to the cleaning pump 57. When it is necessary to rinse the sludge on the surface of the fiber filter cloth, start the cleaning pump 57. Water is pumped into the cleaning pump 57 through the cleaning pipe 51, and then flows through the first connecting pipe 52 and then to the second connecting pipe 53 and the third connecting pipe 54 respectively. With the rotation of the turntable assembly 32, the scraper 55 on the second connecting pipe 53 first scrapes off the dirt on the surface of the fiber filter cloth, and then the cleaning brush 56 on the third connecting pipe 54 sweeps away the scraped impurities, ensuring the cleanliness of the surface of the fiber filter cloth. The fiber filter cloth is cleaned twice, which can thoroughly clean it and improve work efficiency.

[0033] The filter tank 1 is equipped with a cleaning mechanism, which includes slide rails 71 respectively arranged on both sides of the filter tank 1, sliders 72 arranged on the slide rails 71, scrapers 73 for wiping and cleaning the deposited impurities at the bottom of the filter tank 1, and a drive mechanism (not shown in the figure) that drives the sliders 72 to move the scrapers 73 back and forth along the length of the slide rails 71. The slide rails 71 are arranged along the length of the rotating shaft 31 so that the sliders 72 and scrapers 73 can be moved back and forth on the slide rails 72 by the drive mechanism to clean the bottom of the filter tank 1.

[0034] The two ends of the scraper 73 are connected to the slider 72 respectively. The scraper 73 is set vertically, and the bottom of the scraper 73 is in contact with the bottom of the filter tank 1.

[0035] Specifically, the scraper 73 includes a first scraper 731 and a second scraper 732, both of which are made of high-temperature resistant, wear-resistant, wrinkle-resistant, and highly flexible silicone sheets.

The first scraper 731 is set in a vertical direction, and the end face of the second scraper 732 that contacts the filter tank 1 is an inclined surface.

[0036] Furthermore, collection components 74 are provided on both sides of the filter tank 1. Each collection component 74 includes a first structural component 741 and a second structural component 742 connected to each other. The first structural component 741 and the second structural component 742 form a receiving space 743 for deposited impurities. The first structural component 741 has several collection through holes 744. The first structural component 741 is mounted on the filter tank 1 and fits against the bottom of the tank. The second structural component 742 stands upright on one side edge of the first structural component 741. When the scraper 73 moves at the bottom of the filter tank 1, it can push the settled impurities to both sides of the filter tank 1 onto the receiving space 743 of the collection component 744. When the receiving space 743 reaches its maximum capacity of impurities, the collection component 74 can be removed, and the liquid containing impurities will drip down from the collection through holes 744 of the first structural component 741, thus avoiding waste.
