Description

Technical Field

[0001] The utility model relates to the technical field of oil separators, in particular to a self-cleaning backwashing system. Background Art

[0002] The treatment of kitchen waste is one of the more troublesome things in people's daily life. There are a lot of perishable garbage in the kitchen waste, as well as a lot of oil-water mixture, which makes it more troublesome to treat. The existing kitchen waste treatment often uses a grease separator for treatment. The grease separator first separates solid garbage and liquid wastewater, and then pumps out the water after stirring to separate the oil and water. There is perishable garbage in the kitchen waste, so there will be a lot of flocculent garbage, which is difficult to be separated by the solid-liquid separation device and will enter the oil separator with the wastewater. When pumping water, too much flocculent matter can easily block the drainage pipe, which reduces the working efficiency of the water pump and affects the normal operation of the water pump.

[0003] A patent application with announcement number CN213446356U discloses a multifunctional oil separator, which can effectively remove suspended matter, solid grease and floating oil through long-term gravity sedimentation and oil-water separation, eliminating the impact of grease on equipment. The equipment is simple to operate, reliable in operation, low in cost, and semi-underground installed, which can withstand the severe cold in northern winter.

[0004] Since it is difficult for the above-mentioned device to settle the flocs when using a static treatment method, the flocs may easily block the pipes, affecting the discharge of water, and reducing the working efficiency of the water pump inside the device, affecting the normal operation of the water pump. In response to the problem of pump blockage, the present application proposes a self-cleaning backwashing system, the purpose of which is to solve the problem of pump blockage without stopping the machine and prevent damage to the pump blades or reduced efficiency.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0027] like Figure 1 As shown, the utility model is a self-cleaning backwashing system, comprising an oil separator 1, on the top of which is installed a solid-liquid separator 2 for separating solids and liquids in food waste. The solids are removed by the solid-liquid separator 2, and the remaining oil-water mixture flows into the oil separator 1 for oil-water separation. The stirring device 3 rotates at a high speed to cause the oil and water to be separated under the action of centrifugal force. Since the density of oil is lower than that of water, the oil layer will float above the water layer. The water liquid at the bottom is pumped out by the water pump 4, and the backwashing pipeline 5 is used to prevent the pipeline from being blocked by residual garbage.

[0028] Specifically, Figure 6 As shown, a flange 23 is welded at the top of the backwash pipe 5 near the end of the water pump 4, and a reinforcing sleeve 24 is installed through the flange 23, wherein two reinforcing sleeves 24 are arranged side by side;

[0029] A connecting pipe 25 is installed at one end of the reinforcing sleeve 24. The outer surface of the connecting pipe 25 is reinforced by thin sheet reinforcement ribs to prevent the pipe from receiving impact force during backwashing. The port of the connecting pipe 25 changes the size of the pipe opening through a tapered elbow, which can increase the water pressure during backwashing, and conveniently and quickly and efficiently flush the blockage in the pipe. A one-way check valve 21 is installed in both pipes of the backwashing pipe 5. The flushed water and blockage are discharged from the drain port 22 through the one-way check valve 21.

[0030] The process of the embodiment of the utility model is as follows: the kitchen waste first passes through the solid-liquid separator 2, and the solid waste is discharged under the treatment of the solid-liquid separator 2, and the liquid waste water flows into the oil separator 1 and is 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, and the water at the bottom will be discharged through the backwash pipe 5 by the action of the water pump 4. When the pipe is blocked by blockages, the connecting pipe with a tapered bend in the reinforcing sleeve 24 is used to strengthen the connecting pipe with a tapered bend in the blocked side, and water is sprayed out through the pipe mouth to disperse the blockage. The dispersed blockage is discharged from the drain port 22 through the action of the one-way check valve 21, thereby avoiding the situation where the pipe is blocked when draining. Example 2

The movable plate 12 is an L-shaped arc plate and fits with the inner wall of the mesh cover 7. Grooves 13 are provided on both sides of the bottom end of the movable plate 12 and the water outlet pipe 6 on the same horizontal plane. The size of the groove 13 is consistent with the size of half of the water outlet pipe 6, so as to prevent the water outlet pipe 6 from affecting the cleaning of the mesh cover 7;

[0033] A brush 14 is fixed on the outside of the movable plate 12 to clean the mesh cover 7 while preventing garbage from clogging the holes. A movable roller 15 is fixed on the outside of the movable plate 12 so that the movable roller 15 moves along a loop in the annular movable groove 8 of the mesh cover 7.

[0034] The process of the embodiment of the utility model is as follows: in order to prevent the majority of garbage from being sucked into the water pump 4 and clogging the pipeline, a mesh cover 7 is sleeved on the outer surface of the water pump 4 to prevent solid garbage from clogging the holes of the mesh cover 7 and affecting the use effect of the water pump 4; a driving motor 10 is installed at the top center of the mesh cover 7, and a waterproof cover 9 is installed on the outer surface of the driving motor 10 to prevent water from entering the driving motor 10 and affecting the operation of the driving motor 10; the driving motor 10 drives the rotating rod 11 to rotate and then drives the movable plate 12 to rotate in the movable groove 8 in the side wall of the mesh cover 7 through the movable roller 15; the garbage in the holes of the mesh cover 7 is swept out by the brush 14, so that the water pump 4 can work efficiently.
