Technical Field

[0001] This utility model relates to the field of pesticide emulsifiable concentrate processing, and more specifically, to a pesticide emulsifiable concentrate filtration device. Background Technology

[0002] Emulsifiable concentrate pesticides are mainly composed of pesticide technical, emulsifiers and penetrants, and solvents such as methanol and xylene. The resulting emulsifiable concentrate pesticide is pumped into a high-level storage tank for free settling. The supernatant enters the packaging process, while the settling residue is returned to the mixing stage for reprocessing.

[0003] Chinese Patent No. CN202220193426.3 discloses a bag filter for emulsifiable concentrate pesticides. The filter bag is supported by a metal mesh cylinder inside. The emulsifiable concentrate pesticide flows in through the inlet, is filtered by the filter bag, and flows out through the outlet. Impurities are trapped in the filter bag. The filter bag can be replaced and the filter can be used again.

[0004] The applicant discovered the following technical problems when implementing the above-mentioned technical solution: This filtration device cannot be used in conjunction with a shear emulsification device to recycle the filter residue. Instead, the filter bag needs to be removed from the filtration device, replaced, and then the filter residue needs to be cleaned out of the filter bag and transferred to the shear emulsification device for further processing. This is very cumbersome and cannot efficiently recycle the filter residue.

[0005] Therefore, providing a filtration device for pesticide emulsifiable concentrates that can be used in conjunction with a shear emulsification device to recycle the filter residue is a problem that this utility model urgently needs to solve. Utility Model Content

Instead, the existing devices require removing the filter bag from the filtration device, replacing it for continued use, cleaning the filter residue from the bag, and transferring it to the shear emulsification device for further processing. This process is cumbersome and inefficient in recycling the filter residue. Therefore, this invention provides a filtration device for pesticide emulsifiable concentrates that can be used in conjunction with a shear emulsification device to recycle the filter residue.

[0007] To achieve the above objectives, this utility model provides a filtration device for pesticide emulsifiable concentrates. The device includes: a tank, a first conveying pipe, a second conveying pipe, a third conveying pipe, a pump, a conveying mechanism, a first valve assembly, a second valve assembly, and a shearing emulsification mechanism.

After processing, by opening the solenoid valve and the pump, the pesticide emulsifiable oil in the tank is drawn out into the annular filter through the first conveying pipe. The pump draws the pesticide emulsifiable oil from the annular filter through the inlet and pumps it to the next stage through the pump outlet. At this time, larger particles in the pesticide emulsifiable oil will be filtered by the annular filter and thus retained in the annular filter. When the filter residue in the annular filter accumulates to a certain amount, it is then... The first valve assembly is activated to connect the second and third conveying pipes. The filter residue falls into the third conveying pipe under gravity, and then the conveying mechanism transports the filter residue to the side of the second valve assembly. When the filter residue in the third conveying pipe accumulates to a certain amount, the second valve assembly is activated to connect the third conveying pipe to the tank.

The second conveying pipe 3 is disposed on one side of the tank 1 and has an annular filter screen 301 inside it. The outlet of the tank 1 is connected to one end of the first conveying pipe 2 via a solenoid valve. The other end of the first conveying pipe 2 extends into the second conveying pipe 3 and is connected to the annular filter screen 301.

[0024] This application uses a shearing emulsification mechanism 9 to emulsify and shear pesticides within the tank 1. After processing, the pesticide emulsifiable concentrate in the tank 1 is drawn out through the first conveying pipe 2 into the annular filter 301 by opening the solenoid valve and pump 5. The pump 5 draws the pesticide emulsifiable concentrate from the annular filter 301 through the inlet and pumps it to the next stage through the outlet. At this time, larger particles in the pesticide emulsifiable concentrate are filtered by the annular filter 301 and thus retained within the annular filter 301. When the filter residue in the annular filter 301 accumulates to a certain amount, the first valve assembly 7 is activated to... The second conveying pipe 3 is connected to the third conveying pipe 4. The filter residue will fall into the third conveying pipe 4 under the action of gravity. Then, the conveying mechanism 6 will convey the filter residue to the side of the second valve assembly 8. When the filter residue in the third conveying pipe 4 accumulates to a certain amount, the second valve assembly 8 is activated to connect the third conveying pipe 4 to the tank 1. Then, the filter residue is conveyed into the tank 1 through the conveying mechanism 6. Then, an appropriate proportion of water is added into the tank 1, and the shearing emulsification mechanism 9 is activated again for processing. Then, the above cycle is repeated to efficiently recycle the filter residue.

[0025] Reference Figure 3 The conveying mechanism 6 includes a first rotary motor 601 and a conveying screw 602. The conveying screw 602 is adapted to the annular filter screen 301 and is rotatably arranged coaxially within the annular filter screen 301 via the first rotary motor 601.

[0026] This application achieves the conveying of filter residue by starting the first rotary motor 601 to drive the conveying screw 602 to rotate.

[0027] Reference Figure 3 The first valve assembly 7 includes a second rotary motor 701 and a first ball valve 702. The second conveying pipe 3 has a first spherical groove 302 coaxially arranged inside near one end of the third conveying pipe 4, which is adapted to the first ball valve 702. The first ball valve 702 is rotatably arranged in the first spherical groove 302 through the second rotary motor 701, and has a through hole coaxially arranged inside it that is adapted to the second conveying pipe 3.

[0028] When the filter residue in the annular filter screen 301 accumulates to a certain amount, the second rotary motor 701 is started to drive the first ball valve 702 to rotate, thereby connecting the second conveying pipe 3 and the third conveying pipe 4. The filter residue will fall into the third conveying pipe 4 under the action of gravity.

[0032] Users of this application can determine whether it is necessary to open the first valve assembly 7 and the second valve assembly 8 by observing the filter residue viewing window 10.

[0033] Each filter cake viewing window 10 is equipped with a photoelectric sensor on one side.

[0034] This application uses a photoelectric sensor to detect the amount of filter residue in the third conveying pipe 4 and the second conveying pipe 3. When the amount of filter residue reaches a certain level, the light emitted by the light emitter of the photoelectric sensor will be partially absorbed by the filter residue during reflection, and the light received by the light receiver of the photoelectric sensor will be weakened. Then, the signal is transmitted to the PLC control unit, which controls the first valve assembly 7 or the second valve assembly 8 to open and controls the conveying mechanism 6 to send the filter residue into the tank 1. The photoelectric sensor is not shown in the figure.

At the same time, it can also stir the filter residue above the first valve assembly 7 to prevent it from clumping and falling into the third conveying pipe 4 under the action of gravity.

[0039] In use, the device provided by this utility model emulsifies and shears the pesticide within the tank 1 using a shearing emulsification mechanism 9. After processing, the pesticide emulsifiable oil in the tank 1 is drawn out through the first conveying pipe 2 into the annular filter 301 by opening the solenoid valve and pump 5. The pump 5 draws the pesticide emulsifiable oil from the annular filter 301 through the inlet and pumps it to the next stage through the outlet. At this time, larger particles in the pesticide emulsifiable oil are filtered by the annular filter 301 and thus retained within the annular filter 301. When the filter residue in the annular filter 301 accumulates to a certain amount, the first... Valve assembly 7 connects the second conveying pipe 3 and the third conveying pipe 4. The filter residue falls into the third conveying pipe 4 under gravity. Then, the conveying mechanism 6 conveys the filter residue to the side of the second valve assembly 8. When the filter residue in the third conveying pipe 4 accumulates to a certain amount, the second valve assembly 8 is activated to connect the third conveying pipe 4 to the tank 1.
