[0001] The utility model relates to the technical field of oil separators for kitchen waste oil-water separation, in particular to a non-cleaning and convertible filtering device. Background Art

[0002] In the process of treating kitchen waste, an oil separator is often used. There are many perishable wastes in kitchen waste, and there are also many oil-water mixtures, making the treatment rather troublesome. The existing kitchen waste treatment often uses an oil separator. The oil separator first separates solid waste and liquid waste, and then after stirring to separate oil and water, the water is pumped out and discharged. When separating solid-liquid waste, the aperture size of the filter screen used is fixed, which causes many solid wastes with particles smaller than the aperture to fall into the oil separation tank body, easily blocking the pipeline, resulting in poor solid-liquid separation effect and affecting the use efficiency of the oil separator.

Embodiment 1

[0029] As Figure 1 shown, the present utility model is a non - dredging convertible filtering device, including an oil - separating box body 1. At the top of the oil - separating box body 1, a solid - liquid separator 2 for separating solids and liquids in food waste is installed. The solid - liquid separator 2 is used to remove solids, and the remaining oil - water mixture flows into the interior of the oil - separating box body 1 for oil - water separation treatment. Through the high - speed rotation of the stirring device 3, oil and water are stratified under the action of centrifugal force. Since the density of oil is lower than that of water, the oil layer floats above the water layer. Under the action of the water pump 4, the bottom water liquid is pumped out. Through the action of the discharge pipe 5, in order to prevent the residual garbage from blocking the pipe;

[0030] The process of the embodiment of the present utility model is as follows: Kitchen waste first passes through the solid - liquid separator 2. Under the treatment of the solid - liquid separator 2, solid waste is discharged, and the liquid wastewater flows into the oil - separating box body 1 and is quickly stirred by the stirring device 3 to quickly separate oil and water. After standing for a period of time, oil and water will form a stratified state up and down. Under the action of the water pump 4, the water at the bottom is discharged through the discharge pipe 5, avoiding the situation that the pipe is blocked during drainage. Embodiment 2

[0031] As Figures 1-4 shown, the present utility model is a non - dredging convertible filtering device, including a discharging device 6. A motor 7 is installed at the top of the discharging device 6 to drive the discharging paddle 8 to rotate the screen 9. The screen 9 is divided into an upper screen 10 and a lower screen 11. The screen holes of the upper screen 10 and the lower screen 11 are of the same size. The bottom of the upper screen 10 is combined with the groove at the top of the lower screen 11 through a clamping block. A baffle 15 is installed at the top of the screen 9. A spring group 14 is installed in the groove opened inside one side of the baffle 15. The other end of the spring group 14 is fixed with a pull plate 13. The pull plate 13 is fixed to one side of the upper screen 10. A hydraulic push plate 12 is fixed to the other side of the upper screen 10. The hydraulic push plate 12 is fixed inside the baffle 15 and drives the upper screen 10 to move along the surface of the lower screen 11. The upper screen 10 and the lower screen 11 are staggered, so that the size of the holes that can pass through can be adjusted independently. When encountering flocs that block the holes, the flocs can also be cut off;

[0032] Meanwhile, a guide groove 22 is provided on the side of the side sieve 23, and the sides of the upper sieve 10 are slidably arranged in the guide groove 22. When the upper sieve 10 moves along the surface of the lower sieve 11, under the limiting effect of the guide groove 22, the situation of tilting or deforming will not occur, ensuring the stability of the cooperation between the upper sieve 10 and the lower sieve 11.

[0033] Two movable grooves 18 are opened in the baffle 15 on the side plate of the mesh sieve 9. A lead screw 19 is placed inside the movable groove 18. The lead screw 19 drives the movable block 20 to move. The movable block 20 drives the telescopic plate 16 to move on the inner surface of the side plate of the mesh sieve 9 through the rotating rod 21. The bottom end of the telescopic plate 16 is fixed to the inside of the mesh sieve 9 by the fixing nail 17. When the telescopic plate 16 is fixed, it can prevent solid waste from falling during transportation. When the telescopic plate 16 moves, it can push away the waste stagnating in the holes, preventing the holes from being blocked.

[0034] The process of the embodiment of the present utility model is as follows: The hydraulic push plate 12 drives the upper sieve 10. Through the connection between the clamping block installed at the bottom of the upper sieve 10 and the groove at the top of the lower sieve 11, the holes of the upper sieve 10 and the lower sieve 11 are staggered to adjust the size of the holes. When the holes are blocked by flocs, the spring group 14 drives the upper sieve 10 to move back and forth to cut the flocs blocking the holes. In order to prevent the waste from blocking the side plate of the mesh sieve 9, a movable groove 18 is opened in the baffle 15 at the top of the mesh sieve 9. The lead screw 19 in the movable groove 18 drives the movable block 20 to move, and then drives the top end of the telescopic plate 16 to move. Under the condition that the bottom end of the telescopic plate 16 is fixed by the fixing nail 17, the shaking of the bottom end of the telescopic plate 16 is avoided. By connecting the top end of the telescopic plate 16 to the rotating rod 21 and the movable block 20, it is convenient to drive the top end of the telescopic plate 16 to move, which can push away the waste stagnating in the holes, preventing the holes from being blocked. When the telescopic plate 16 is fixed, it can prevent solid waste from falling during transportation.

[0035] Working principle of the utility model: The kitchen waste first passes through the solid-liquid separator 2. Under the treatment of the solid-liquid separator 2, the solid waste is discharged. When solid-liquid separation is carried out, in order to prevent the solid waste from entering the oil separation box body 1 through the holes of the screen 9, the hydraulic push plate 12 drives the upper screen 10. Through the connection between the clamping blocks installed at the bottom of the upper screen 10 and the grooves at the top of the lower screen 11, the holes of the upper screen 10 and the lower screen 11 are staggered to adjust the size of the holes. When the flocculants block the holes, the upper screen 10 is driven to move back and forth by the spring group 14 to cut off the flocculants blocking the holes. In order to prevent the waste from blocking the side plates of the screen 9, an activity groove 18 is opened in the baffle 15 at the top of the screen 9. The lead screw 19 in the activity groove 18 drives the moving block 20 to move, and then drives the top of the telescopic plate 16 to move. When the bottom end of the telescopic plate 16 is fixed by the fixing nail 17, the bottom end of the telescopic plate 16 is prevented from shaking. The top of the telescopic plate 16 is connected to the rotating rod 21 and the moving block 20, which is convenient to drive the top of the telescopic plate 16 to move and can push away the waste stagnating in the holes to prevent the holes from being blocked. When the telescopic plate 16 is fixed, it can prevent the solid waste from falling during transportation, so that the waste water can flow into the oil separation box body 1 and be quickly stirred by the stirring device 3 to quickly separate the oil and water. After standing for a period of time, the oil and water will form an upper and lower stratified state. Under the action of the water pump 4, the water at the bottom is discharged through the discharge pipe 5, avoiding the situation of the pipeline being blocked during drainage.
