Positional designations selected in the description, such as top, bottom, lateral, etc., also refer to the directly described and illustrated figures and are transferred to the new position in the event of a change in position.

[0024] Example 1

[0025] Automatic cleaning device for filter residue of frame filter, such as Figures 1-6 As shown, it includes a frame filter 1, a filter plate 2, a spray pipe 3, an electric slide rail 4, a movable frame 5, a fixed rod 6, a motor 7, a screw 8, a diverter plate 9, a bellows 901, a water outlet pipe 10 and a nozzle 11. A plurality of filter plates 2 are arranged inside the frame filter 1. A spray pipe 3 is fixedly connected to the right side of the frame filter 1 in a front-to-back symmetrical manner. The spray pipe 3 is used to clean the filter residue on the side of the frame filter 1. An electric slide rail 4 is symmetrically provided on the top of the frame filter 1. A movable frame 5 is fixedly connected between the two electric slide rails 4. The electric slide rail 4 is used to drive the movable frame 5 to move by starting the electric slide rail 4. The top of the mobile frame 5 is fixed with a fixed rod 6, the top of the fixed rod 6 is fixed with a motor 7, the motor 7 is connected to a screw 8 through a coupling, the bottom of the screw 8 is rotatably connected to the mobile frame 5, the top of the screw 8 is threadedly connected to a diverter plate 9, the top of the diverter plate 9 is fixed with a bellows 901, the bellows 901 can be stretched and folded according to the up and down movement of the diverter plate 9, so as to facilitate the delivery of clean water to the diverter plate 9, four rows of water outlet pipes 10 are fixed to the bottom of the diverter plate 9, and there are five in each row. A nozzle 11 is fixed between the bottom of every four water outlet pipes 10 parallel to the filter plate 2.

[0026] like Figure 1As shown, a glass frame is also included. Glass frames are provided on both the front and rear sides of the frame filter 1 to prevent splashing of flushing water.

[0027] After the frame filter 1 has filtered the material, filter residue will remain on the multiple filter plates 2 that are spaced apart. Some of the filter residue is blocked on the filter screen and is difficult to clean. Therefore, people can use this device to automatically clean the filter residue. First, manually control the frame filter 1 to space the multiple filter plates 2 at equal intervals. Then, a large amount of filter residue will fall between the spaced filter plates 2. Then, manually control the spray pipe 3 to clean the filter plates 2 and the filter residue on the sides of the frame filter 1. Then, manually start the electric slide 4 to move to the right and stop just above the space between the filter plates 2. Then, turn off the electric slide 4 and manually control the motor 7. The drive drives the screw 8 to rotate, and then drives the diverter plate 9 to move downward at a uniform speed and drives the bellows 901, the water outlet pipe 10 and the nozzle 11 to move downward. The water outlet pipe 10 and the nozzle 11 are located at the interval of the filter plate 2. When the diverter plate 9 moves downward, the bellows 901 is stretched, and the nozzle 11 sprays water to rinse the filter plate 2, and cleans the more stubborn filter residue of the filter plate 2. After cleaning, the motor 7 is manually controlled to drive the reverse direction, and the diverter plate 9, the bellows 901, the water outlet pipe 10 and the nozzle 11 are reset, thereby cleaning the filter residue blocked in the filter plate 2.

[0028] Example 2

[0029] On the basis of Example 1, Figure 1 and Figure 4 As shown, it also includes a sliding frame 12, a wedge block 13, a limit rod 14 and an elastic member 15. The movable frame 5 is symmetrically slidably connected to the sliding frame 12 in the front and rear directions. A wedge block 13 is fixed to the bottom of the sliding frame 12. The wedge block 13 is made of aluminum alloy. When the inclined surface of the wedge block 13 contacts the filter plate 2, the damage to the wedge block 13 is reduced. The upper part of the sliding frame 12 is fixed to the limit rod 14. The elastic member 15 is wound around the upper part of the sliding frame 12. The two ends of the elastic member 15 are respectively connected to the limit rod 14 and the movable frame 5. When the movable frame 5 moves to the right, the inclined surface of the wedge block 13 will contact the filter plate 2, and the filter plate 2 can be knocked under the action of the elastic member 15.

[0030] The filter residue blocked on the filter plate 2 requires high-pressure washing for a period of time to be cleaned. When the electric slide rail 4 is manually controlled to move to the right, the sliding frame 12, the wedge block 13, the limit rod 14 and the elastic member 15 will be driven to move through the moving frame 5. When the moving frame 5 moves to the right, the inclined surface of the wedge block 13 will contact the filter plate 2, causing the wedge block 13, the sliding frame 12 and the limit rod 14 to move upward. At this time, the elastic member 15 will be stretched. When the moving frame 5 moves to the interval between the filter plates 2, the elastic member 15 will be reset, driving the sliding frame 12, the wedge block 13 and the limit rod 14 to move downward. The sliding frame 12 hits the filter plate 2 to generate vibration, thereby vibrating the filter residue on the filter plate 2, thereby achieving convenient and fast cleaning of the filter residue blocked on the filter plate 2.

[0031] like Figure 1 and Figure 5 As shown, it also includes a fixing frame 16, a blower 17 and an air separation frame 18. The fixing frame 16 is fixed between the left parts of the two electric slide rails 4, the blower 17 is fixed to the upper part of the fixing frame 16, and the air separation frame 18 is fixed to the bottom of the fixing frame 16. The air separation frame 18 is connected to the blower 17, and the air outlet of the air separation frame 18 is trapezoidal in shape, which is conducive to blowing away the liquid on the filter plate 2.

[0032] After cleaning with clean water, there will be residual clean water on the filter plate 2. Then, the electric slide 4 is manually started to move to the right, and the blower 17 is started. When the electric slide 4 moves to the right, it drives the fixed frame 16, the blower 17 and the air distribution frame 18 to move to the right. The liquid remaining on the filter plate 2 is blown away by the blower 17 to keep the filter plate 2 clean after cleaning.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
