Description

Technical Field

[0001] The utility model relates to the technical field of pesticide production, in particular to a secondary filtering device for pesticide impurities. Background Art

[0002] Pesticides can be used to kill insects, fungi and other organisms that harm crop growth. The earliest pesticides used were DDT, BHC, etc. They could eliminate a large number of pests, but they had good stability, could exist in the environment for a long time, and accumulated continuously in animals, plants and the human body. Therefore, they were phased out. Later, organophosphorus pesticides such as dichlorvos were used to replace the original pesticides. Due to their high toxicity and great harm to humans and livestock, in recent years, a batch of highly efficient and low-toxic pesticides have emerged, which are specific, that is, hormone pesticides. Before pesticides are used, a filtering device is needed to filter the impurities contained in the pesticides.

[0003] For example, a impurity filtering device for pesticide production disclosed in Chinese Patent (CN213253245U) includes a device main body. An inlet is provided on the top surface of the device main body. A filter plate is inserted on the inner wall surface of one side of the device main body, and a filtering mechanism is inserted inside the filter plate. The filtering mechanism includes a connecting frame. The connecting frame is inserted inside the filter plate, and a filter screen is inserted inside the connecting frame. L-shaped blocks are fixedly connected to both side surfaces of the connecting frame. The device is provided with a filtering mechanism and a clamping mechanism. The filtering mechanism is beneficial to cooperate with the inclined surface of the filter plate to filter the liquid pesticide put in from the inlet. At the same time, the blocks are L-shaped and are arranged in the grooves on the inner wall surface of the filter plate, and are clamped on the inner wall surface of the filter plate, so that the connecting frame and the filter screen are clamped inside the filter plate, which is convenient to pick up the top of the block to take out the filtering mechanism after filtering.

[0004] The above solution still has the following technical deficiencies. The above solution uses a single filter screen for filtering. Although this method is simple and easy to implement, it has poor removal effects on fine impurities and impurities dissolved in the solvent, and cannot ensure the high purity of pesticide products. It may cause impurities that affect the efficacy or use safety in the products. Based on this, a secondary filtering device for pesticide impurities is proposed. Summary of the Utility Model

The second filter frame 205 is fixed by screwing the screw 208 into the second fixing block 207.

[0038] It should be noted that the first filter frame 202 can be limited by abutting the first fixing block 201 in the first installation groove. At the same time, the screw 208 and the second fixing block 207 can fix the second filter frame 205, thereby indirectly fixing the first filter frame 202 in the up and down directions.

[0039] Please refer to Figure 1 and Figure 4, in order to facilitate the flushing of the first filter screen 203 and the second filter screen 206, the flushing mechanism 300 in this embodiment includes a water pump 301 fixed on the right side of the filter tank 1, a water inlet pipe 302 fixed at the input end of the water pump 301, a water outlet pipe 303 fixed at the output end of the water pump 301, and a flushing assembly installed between the left and right side walls of the filter tank 1.

[0042] All the electrical components mentioned in the text are electrically connected to the controller and the power supply. The control mode of the present invention is controlled by the controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art. And the present invention is mainly used to protect mechanical devices, so the control mode and the circuit connection of the present invention will not be explained in detail.

[0043] The working principle of the above embodiment is as follows:

[0044] When it is necessary to filter pesticides, unscrew the pipe cap 5, pour the pesticides into the filter box 1 through the liquid inlet pipe 4. The first filter screen 203 preliminarily filters the larger impurities in the pesticides. Then, the smaller impurities in the pesticides are filtered out by the second filter screen 206. After being filtered, the pesticides fall into the bottom side of the filter box 1 through the gap between the front and rear sides of the hollow plate 304 and the corresponding inner wall of the filter box 1. Open the first valve, and the liquid outlet pipe 6 discharges the filtered pesticides. Then, the first filter screen 203 and the second filter screen 206 are rinsed to facilitate the next filtration. Start the water pump 301, open the second valve, and the water pump 301 pumps clear water into the water inlet pipe 302. Then, the clear water is introduced into the hollow plate 304, and the hollow plate 304 disperses the clear water. Then, the clear water sprays out from the spray pipe 305 and the spray head 306, and the clear water rinses the impurities blocked in the first filter screen 203 and the second filter screen 206. When it is necessary to take out the first filter screen 203 and the second filter screen 206 for cleaning, open the movable door, turn the handle 210, and the handle 210 drives the screw rod 208 to rotate. The screw rod 208 is separated from the second fixing block 207, and the screw rod 208 is removed from the through hole. Then, move the second filter frame 205 upward, and the second filter frame 205 drives the vertical rod 204 and the first filter frame 202 to move upward. Take out the first filter frame 202 and the second filter frame 205 from the front side of the filter box 1, pour out the impurities on the first filter screen 203 and the second filter screen 206, and then install the first filter screen 203 and the second filter screen 206 back.
