Description

Technical Field

[0001] This utility model relates to the technical field of herbicide production equipment, specifically to a filtration and purification device for herbicide preparation. Background Technology

[0002] Herbicides are pesticides that can cause weeds to die completely or selectively. They are a class of substances used to kill or inhibit plant growth. Sodium chlorate, borax, arsenic, and trichloroacetic acid among them have a killing effect on any type of plant. Their effectiveness is affected by three factors: the herbicide, the plant, and environmental conditions. Herbicides are classified into non-selective and selective herbicides according to their effects. Selective herbicides, especially derivatives of nitrophenol, chlorophenol, and carbamic acid, are mostly effective. The development of herbicides worldwide is gradually stabilizing, with a focus on developing highly efficient, low-toxicity, broad-spectrum, and low-dosage varieties. Single-use herbicides with low environmental pollution are gradually becoming the mainstream.

[0003] However, many existing liquid herbicides inevitably contain solid particulate impurities during the production process, which affects the purity of the herbicide and thus impacts product quality to some extent. Therefore, this invention provides a filtration and purification device for herbicide preparation to solve the above problems. Utility Model Content

[0004] This invention proposes a filtration and purification device for herbicide preparation.

[0023] Example 1

[0024] like Figures 1-5As shown, this embodiment proposes a filtration and purification device for herbicide preparation, including a processing chamber 1. A feed hopper 2 is fixedly installed at the top of the processing chamber 1. A slot 3 is longitudinally opened on the right outer wall of the processing chamber 1. An installation box 4 is fixedly installed on the right outer wall of the processing chamber 1. The processing chamber 1 is connected to the installation box 4 through the slot 3. A sieve plate 5 is rotatably installed on the left inner wall of the processing chamber 1. The right side of the sieve plate 5 extends into the installation box 4 through the slot 3. A first sliding groove 6 is transversely opened inside the installation box 4. A collection box 7 is installed, and a first handle 8 is fixedly installed on the outer right side of the collection box 7. Several sets of filter holes 9 are opened on both the sieve plate 5 and the collection box 7. A second slide groove 16 is opened on the left side of the processing chamber 1. A nanofiltration membrane filter plate 17 is slidably installed inside the second slide groove 16. A third handle 18 is fixedly installed on the outer left side of the nanofiltration membrane filter plate 17. A connecting pipe 401 is fixedly installed on the outer right side of the processing chamber 1 above the second slide groove 16. The other end of the connecting pipe 401 is connected to the bottom end of the installation box 4.

[0025] Mounting box 4 has vertically formed mounting slots 10 on both the front and rear ends of its right outer wall. Guide rods 11 are vertically fixedly installed inside each of the two sets of mounting slots 10. A slider 12 is slidably installed inside each set of mounting slots 10. A baffle 13 is provided on the right side of mounting box 4. The right sides of the two sets of sliders 12 are fixedly connected to the baffle 13. Springs 14 are fitted on both sets of guide rods 11. The top of each set of springs 14 is fixedly connected to the top of the mounting slot 10 at the corresponding position. The bottom of each set of springs 14 is fixedly connected to the slider 12 at the corresponding position. A second handle 15 is fixedly installed on the right outer wall of the baffle 13.

[0026] A first sealing gasket is fixedly installed at the connection between the collection box 7 and the outer surface of the first slide 6, and a second sealing gasket is fixedly installed at the connection between the nanofiltration membrane filter plate 17 and the outer surface of the second slide 16.

[0027] A fixed pipe 22 is fixedly installed at the bottom of the processing chamber 1, and a transfer chamber 23 is fixedly installed at the other end of the fixed pipe 22. A discharge valve 24 is fixedly installed at the front end of the transfer chamber 23. A second rotating shaft 25 is longitudinally rotatably installed inside the transfer chamber 23. Several sets of stirring rods 26 are fixedly installed on the second rotating shaft 25. A second motor 27 is fixedly installed on the outer wall of the rear end of the transfer chamber 23. The output end of the second motor 27 is fixedly connected to the second rotating shaft 25.

[0028] The first motor 21 and the second motor 27 are both servo motors; a control panel 29 is fixedly installed on the outer wall of the front end of the processing chamber 1; rubber pads 28 are fixedly installed at the four corners of the bottom of the processing chamber 1.

[0029] In this embodiment, for ease of control, the first motor 21, discharge valve 24, and second motor 27 are all electrically connected to the control panel 29. When using this device, the operator first adds liquid herbicide into the processing chamber 1 through the feed hopper 2. This allows the solid particulate impurities in the herbicide to be filtered through the filter holes 9 on the sieve plate 5, thus improving the purity of the herbicide to some extent. Simultaneously, the filtered solid particulate impurities are collected in the collection box 7 through the sieve plate 5. The herbicide adhering to the solid impurities can then flow back into the processing chamber 1 through the connecting pipe 401, reducing herbicide loss and improving the practicality of the device. Furthermore, in this device, when the collection box 7 is slidably installed into the first sliding... Inside the tank 6, the baffle 13, under the action of the spring 14, limits the position of the collection box 7, making the collection box 7 more stable during use. Then, when the herbicide passes through the nanofiltration membrane filter plate 17, it can be filtered again. The nanofiltration membrane filter plate 17 can effectively remove some harmful metal ion impurities, while minimizing the loss of the active ingredients in the herbicide, thereby further improving the purity of the herbicide and ensuring the quality of the finished herbicide to a certain extent. Finally, when it is necessary to discharge the herbicide, the operator can open the discharge valve 24 through the control panel 29 and start the second motor 27, which can drive the stirring rod 26 to stir the herbicide, so that the various components of the herbicide are mixed more evenly.

[0030] Example 2

[0031] like Figures 1-5 As shown, based on the same concept as in Embodiment 1 above, this embodiment also proposes that a first rotating shaft 19 is longitudinally rotatably installed inside the processing chamber 1, an eccentric wheel 20 is fixedly installed on the first rotating shaft 19, the top end of the eccentric wheel 20 is in contact with the bottom end of the sieve plate 5, and a first motor 21 is fixedly installed on the outer wall of the rear end of the processing chamber 1, and the output end of the first motor 21 is fixedly connected to the first rotating shaft 19.

[0032] In this embodiment, when the worker adds the liquid herbicide into the processing chamber 1 through the feed hopper 2, the worker can start the first motor 21 set by the control panel 29, so that the eccentric wheel 20 can be driven to rotate, thereby continuously hitting the bottom of the sieve plate 5, which can effectively reduce the occurrence of clogging of the filter holes 9, thereby further improving the practicality of the device.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
