Description

Technical Field

[0001] This invention relates to the field of diuron mother liquor production, and particularly to a diuron mother liquor treatment device. Background Technology

[0002] Diuron is a broad-spectrum herbicide commonly used in agricultural production. Diuron mother liquor refers to an aqueous solution containing the main component of diuron. When using diuron mother liquor, it is necessary to strictly follow the concentration and dosage provided in the instructions to prevent adverse effects on farmland, the environment, and human health. The production of diuron mother liquor generally includes solid raw material preparation, reaction preparation, and processing filtration. Processing filtration typically involves filtering and separating the mother liquor after the reaction to remove impurities and insoluble substances.

[0003] Chinese Utility Model Patent Application No. 202321332505.9 discloses a diuron mother liquor treatment device. This device includes: a reaction tank with an open top, a support frame fixed to the bottom for support, and a drain valve fixed to one side of the bottom of the reaction tank; a cover plate placed on top of the reaction tank. In preparing diuron mother liquor, both solid and liquid diuron raw materials are added to an inner tank for reaction and mixing. After mixing, the drain valve is opened to discharge the diuron mother liquor. An electric actuator moves a pressing plate towards the inner tank to squeeze and dehydrate the liquid raw material adsorbed in the solid raw material. After squeezing, the electric actuator moves the pressing plate closer to the cover plate, causing a locking element to engage with the inner tank. Through the cooperation of a driving element and the electric actuator, the inner tank can be moved above the reaction tank, releasing the locking element and allowing for disassembly of the inner tank. This facilitates the cleaning of the solid raw material, impurities, and insoluble substances inside the inner tank.

[0004] The aforementioned prior art uses a squeezing method in conjunction with a filter screen for dehydration. However, during squeezing dehydration, the filter screen is easily clogged by solids, and the clogging becomes more and more serious as the squeezing continues, which in turn affects the discharge of liquid. Moreover, cleaning requires lifting and disassembling the filter screen, which is time-consuming, labor-intensive, and inefficient.

[0005] Therefore, it is necessary to propose a mother liquor treatment device for diuron to solve the above problems. Summary of the Invention

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example

[0036] like Figures 1-9 As shown, in this embodiment, a diuron mother liquor treatment device includes a treatment cylinder 1, a cover plate 2 disposed at the top of the treatment cylinder 1, and an outlet 3 disposed at the lower end of one side of the treatment cylinder 1.

The end of the second drive shaft 29 away from the filter screen 32 extends to the inner side of the transmission box 6 and is fixedly connected to one end of the lower rotating shaft 33.

[0040] To prevent liquid from impacting the transmission box 6, a connecting cylinder 28 is provided at the end of the discharge port 3 away from the treatment cylinder 1, and a liquid outlet 31 is provided at the bottom of the connecting cylinder 28 near the discharge port 3.

[0041] In addition, to facilitate liquid loading, a liquid loading assembly is provided on the extrusion plate 16. The liquid loading assembly includes a third through hole 23 at one end of the top of the extrusion plate 16. An inlet 4 is provided at the top of the extrusion plate 16 corresponding to the third through hole 23. A second through hole 22 corresponding to the inlet 4 is provided at one end of the top of the cover plate 2, and the upper end of the inlet 4 extends to the top of the cover plate 2 through the second through hole 22. A scraper 30 is provided at the bottom of the extrusion plate 16. A sealing plate 24 is movably provided inside the scraper 30. A second reduction motor 21 for driving the sealing plate 24 to rotate is provided at the top of the extrusion plate 16.

A base plate 26 is provided at the bottom of the sealing plate 24.

[0042] To facilitate the discharge of solids, a solid discharge mechanism is provided at the bottom of the processing cylinder 1. The solid discharge mechanism includes a bottom box 5 located at the bottom of the processing cylinder 1. A first through hole 9 corresponding to and adapted to the bottom of the processing cylinder 1 is provided at one end of the top of the bottom box 5. A sealing plate 10 adapted to the first through hole 9 is movably provided on the inner side of the bottom of the bottom box 5. A connecting seat 11 is provided at one end of the bottom of the connecting seat 11. An electric push rod 13 is installed on the inner side of the bottom of the bottom of the bottom box 5 away from the first through hole 9 through a mounting bracket 12. The mounting bracket 12 is located below the sealing plate 10. The output shaft end of the electric push rod 13 is fixedly connected to the connecting seat 11, thereby driving the sealing plate 10 to move horizontally through the connecting seat 11.

[0043] Furthermore, in order to increase the stability of the sealing plate 10, guide grooves 14 are symmetrically arranged on the front and rear sides of the upper end of the bottom cavity of the bottom box 5, and the two ends of the sealing plate 10 are slidably connected to the inner side of the guide grooves 14; in order to increase the sealing performance, a flexible sealing ring 15 is provided at the bottom edge of the first through hole 9, and the flexible sealing ring 15 is in close contact with the top of the sealing plate 10.

[0044] Working principle: During use, the raw liquid is added through inlet 4. During this process, the second reduction motor 21 drives the sealing disc 24 to rotate continuously. Therefore, the fourth through hole 25 will continuously overlap and offset with the third through hole 23. When they overlap, the raw liquid falls between the base plate 26 and the arc plate 27. As the sealing disc 24 rotates, the raw liquid between the base plate 26 and the arc plate 27 is thrown out, and then the raw liquid will fall evenly to the bottom area of ​​the processing cylinder 1. After the raw liquid is added, the third through hole 23 is positioned between two of the fourth through holes 25, and the sealing disc 24 seals the third through hole 23. Then, the first reduction motor 7 is started, which drives the synchronous pulley 34, the rotating shaft 33, and the synchronous belt 35 to rotate, thereby... The rotating shaft 33 drives the first drive shaft 8 and the second drive shaft 29 to rotate respectively. The first drive shaft 8 drives the gear 18 to rotate, and the gear 18 drives the extrusion plate 16 to move downward and extrude through the rack 17. The liquid is discharged after being filtered through the filter screen 32, and the solid remains in the lower inner side of the processing cylinder 1. During this period, the second drive shaft 29 drives the scraper 30 to continuously clean the surface of the filter screen 32 to avoid clogging and affecting the discharge of the liquid. When the liquid is discharged, it will be discharged through the liquid outlet 31. After the extrusion and dehydration are completed, the electric push rod 13 is activated to drive the sealing plate 10 to move, and then the solid falls through the first through hole 9. In order to ensure that all the solid falls, the extrusion plate 16 can continue to move downward to push the solid out.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
