Description

Technical Field

[0001] The utility model relates to the technical field of emulsion recovery and treatment, in particular to a filtering and treatment device for emulsion recovery. Background Art

[0002] Emulsion is a high-performance semi-synthetic metalworking fluid, especially suitable for the processing of aluminum and its alloys, but not for materials containing lead, such as some brasses and tin metals. Emulsion is a special formula without chlorine, specially designed to solve various problems that occur when processing aluminum and its alloys (such as: chip adhesion, tool wear, poor surface accuracy of the workpiece and surface contamination). It can be used for all operations including reaming. Emulsion can also effectively prevent the workpiece from rusting or chemical corrosion.

[0003] The emulsion can be recycled and reused. Since the waste emulsion mainly contains emulsified oil, surfactants, additives and metal chips or metal particles, the recycling steps are mainly filtering to remove metal chips or other impurities, then breaking the emulsion to achieve oil-water separation, and then deep treatment to remove residual organic matter and metal ions, and finally recycling and reusing to form a closed loop cycle, saving costs and reducing the impact of waste emulsion on the environment. In the filtration process, the existing device generally uses a filter screen to filter, but the impurities such as metal chips trapped by the filter will accumulate and then clog the filter screen, affecting the water flow. At present, most of them are cleaned manually, and these metal chips can easily cause damage to the hands of the staff, resulting in low practicality of the device. The Chinese utility model patent with the authorization announcement number CN 220328050 U discloses an energy-saving and environmentally friendly emulsion recycling device, which uses an electromagnet to collect metal chips, but this method is only suitable for metals such as iron, cobalt, and nickel. For aluminum alloys that are often used in large quantities in emulsions, this method cannot be used at all, the scope of application is too small, and the limitations are too large. Utility Model Content

[0019] An embodiment of a filtering treatment device for emulsion recovery of the utility model is as follows Figure 1-Figure 3As shown, it includes an emulsion water inlet pipe 4, a treatment box 1, a water inlet box 3 and a sedimentation box 2. A filter screen 12 is arranged in the treatment box, and a water outlet pipe 13 is provided at the bottom of the treatment box, which is used to discharge the emulsion after the filtration treatment for subsequent demulsification treatment. In the treatment box, the filter screen is arranged obliquely so that an impurity gathering area is formed at the lowest position of the filter screen. The wall of the treatment box is connected with the sedimentation box 2 through a first connecting pipe 17 at the lowest position, and a first valve is arranged on the first connecting pipe. A first water inlet 14 is arranged at the lowest position on the treatment box for flushing impurities in the impurity gathering area into the sedimentation box. Among them, the first water inlet 14 and the first connecting pipe 17 are arranged on the two box walls of the treatment box opposite to each other, so as to flush the impurities in the impurity gathering area into the sedimentation box.

[0020] A cleaning mechanism is provided above the filter screen on the processing box, which is used to sweep the metal chips on the filter screen to the impurity gathering area below during cleaning. The cleaning mechanism includes a cleaning brush 8 and a moving mechanism that drives the cleaning brush to move parallel to the inclination direction of the filter screen, so as to sweep the metal chips on the filter screen to the impurity gathering area, and the cleaning mechanism also includes a rotating mechanism that drives the cleaning brush to rotate. Specifically, the moving mechanism includes a guide slot 6 provided on two opposite box walls of the processing box, and the length direction of each guide slot is parallel to the plane where the filter screen is located. A guide block 7 is installed in each guide slot for guiding movement, and the two ends of the cleaning brush are respectively installed on the corresponding guide block through a rotating shaft. A first gear 10 and a first motor 11 that drives the first gear to rotate are rotatably provided on one of the guide blocks, and a rack 9 meshing with the first gear is provided on the box wall of the processing box, and the length direction of the rack is parallel to the length direction of the guide slot on the corresponding side of the rack. The movement and cleaning of the cleaning brush are realized by the first motor, the first gear and the rack.

[0021] The rotating mechanism includes a second gear disposed on a rotating shaft on one side, a third gear meshing with the second gear and a second motor 15 driving the third gear to rotate are rotatably disposed on the side guide block, and the cleaning brush angle is adjusted by the second motor and the second and third gears. The adjustment of the cleaning brush angle can achieve the cleaning brush being turned away from the liquid surface of the emulsion when cleaning is not needed, without affecting the sliding and aggregation of metal chips, and can also extend the life of the cleaning brush. In this embodiment, the first motor and the first gear are disposed on the guide block on one side, and the second motor, the second gear and the third gear are disposed on the guide block on the other side. That is to say, the cleaning brush is moved on one side of the processing box, and the other side is responsible for the rotation of the cleaning brush.

[0022] The water inlet tank is separated from the treatment tank by a partition, and a connecting port 19 is provided on the partition. The position of the connecting port is higher than the bottom of the water inlet tank so that the part of the water inlet tank wall below the connecting port forms a chip guard. The bottom of the water inlet tank is tilted so that the chip guard is at the lowest point of the water inlet tank. The emulsion water inlet pipe 4 is located above the highest point of the water inlet tank. The water inlet tank 3 is connected to the sedimentation tank through a second connecting pipe 18, and a second valve is provided on the second connecting pipe. A second water inlet 20 is provided at the lowest point on the wall of the water inlet tank. The second water inlet and the second connecting pipe are relatively arranged on two opposite walls of the water inlet tank, which are used to flush the metal chips gathered at the chip guard into the sedimentation tank. A pumping pipe 16 is provided in the sedimentation tank for extracting the supernatant in the sedimentation tank. The pumping pipe 16 is connected to the first water inlet 14 through the first pipe 22 and to the second water inlet 20 through the second pipe 21. A water pump is provided on the pumping pipe. The first water inlet is provided with a third valve, and the second water inlet is provided with a fourth valve. A sewage pipe is provided at the lower part of the sedimentation tank.

[0023] When in use, the waste emulsion first enters the water inlet tank. Due to the existence of the chip guard plate, part of the metal chips in the water inlet tank are blocked by the chip guard plate, and the emulsion enters the treatment tank for filtration. Under the impact of the emulsion, most of the metal chips will gather in the impurity gathering area of ​​the treatment tank. There will also be some metal chips on the filter screen. These metal chips are cleaned by the cleaning brush to the impurity gathering area. The metal chips in the water inlet tank and the metal chips in the treatment tank are washed by the second water inlet and the first water inlet respectively, and enter the sedimentation tank.
