Description

Technical Field

[0001] This utility model belongs to the field of chemical production technology, specifically relating to a continuous adsorption device for quinacrine technical. Background Technology

[0002] Quinalazine is a novel triketone 4-HPPD herbicide containing a quinazolinidone structure. Preparing it as a nanoparticle can significantly improve its efficacy and utilization rate. In existing quinalazine nanoparticle preparation processes, hollow mesoporous silica particles are commonly used as ideal adsorption carriers due to their large specific surface area, regular pore structure, and excellent adsorption performance. However, most existing adsorption devices operate intermittently, resulting in low production efficiency, high energy consumption, and difficulty in precisely controlling adsorption conditions, failing to meet the demands of continuous adsorption of quinalazine nanoparticles for large-scale industrial production. Therefore, it is urgent to solve these problems in practical production. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a continuous adsorption device for quinacrine technical material. This device overcomes the defects in the prior art, realizes continuous and automated adsorption production of quinacrine nano-technical material, significantly improves production efficiency, reduces production costs, and effectively meets the needs of large-scale industrial production.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A continuous adsorption device for quinacrine technical grade includes a mixer equipped with a stirring device. The top of the mixer has a liquid inlet and a solid inlet. The liquid inlet of the mixer is connected to a technical grade solution storage tank via a pipeline and a first metering pump. The solid inlet of the mixer is connected to a silica storage tank via a pipeline and a second metering pump. The bottom of the mixer has a material outlet. The material outlet of the mixer is connected to the inlet of a spiral conveyor adsorption device equipped with a heating jacket via a pipeline. The outlet of the spiral conveyor adsorption device is connected to a centrifuge via a pipeline. The solid outlet of the centrifuge is connected to a quinacrine product storage tank via a pipeline.

[0006] Preferably, the inlet of the technical grade solution storage tank is connected to both the quinacrine technical grade storage tank and the dichloromethane storage tank via pipes, valves, and a pump. Quinacrine technical grade can be prepared into a 20% quinacrine dichloromethane solution.

[0007] Preferably, both the first metering pump and the second metering pump are electrically connected to the DCS automatic control system.

[0008] Preferably, both the first metering pump and the second metering pump are model GM-1000 / 0.2.

[0009] Preferably, the spiral conveying adsorption device includes a drive motor and a spiral conveying adsorption tube with a heating jacket. The spiral conveying adsorption tube has a heating jacket on its tube wall, an inlet at one end near the drive motor, and an outlet at the other end.

[0010] Furthermore, the drive motor is electrically connected to the DCS automatic control system.

[0011] Preferably, the spiral conveyor adsorption device is model GX600.

[0012] Preferably, the centrifuge model is SME-1500.

[0013] Preferably, the liquid outlet of the centrifuge is connected to a dichloromethane recovery tank via a pipeline.

[0014] Due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] This invention first prepares a 20% quinacrine nanoparticle technical material solution using quinacrine dichloromethane. Then, the 20% quinacrine dichloromethane solution is quantitatively fed into a mixer along with hollow mesoporous silica powder for mixing. The mixed material is then conveyed into a spiral conveyor adsorption tube while being heated. During the conveying process, the silica powder adsorbs quinacrine. The adsorption time is controlled by setting the material conveying speed to ensure complete adsorption of quinacrine. Finally, the solvent and solid material are separated by a centrifuge to obtain the adsorbed quinacrine nanoparticle technical material product. The separated solvent is reused. Compared with traditional intermittent adsorption devices, this production process greatly improves production efficiency and reduces production costs.

[0016] In summary, this invention enables continuous and automated adsorption production of quinacrine nanoparticles, significantly improving production efficiency, reducing production costs, and effectively meeting the needs of large-scale industrial production. Attached Figure Description

The top of the mixer 1 is provided with a liquid inlet (not shown) and a solid inlet (not shown). The liquid inlet of the mixer 1 is connected to the technical grade solution storage tank 3 through a pipeline (not shown) and a first metering pump 2.

The material outlet of the mixer 1 is connected to the inlet of a spiral conveyor adsorption device 6 equipped with a heating jacket (not shown) through a pipeline. The outlet of the spiral conveyor adsorption device 6 is connected to a centrifuge 7 through a pipeline. The solid outlet of the centrifuge 7 is connected to a quinacrine product storage tank (not shown) through a pipeline.

[0022] The spiral conveyor adsorption device 6 includes a drive motor 61 and a spiral conveyor adsorption tube 62 equipped with a heating jacket.

[0023] In actual production: 200g of quinacrine technical and 800g of dichloromethane are added to the technical solution storage tank 3 and stirred until quinacrine is completely dissolved to obtain a 20% quinacrine dichloromethane solution; 50g of hollow mesoporous silica powder is added to the silica storage tank 5; then, the flow rate of the first metering pump 2 is set to 100ml / min and the flow rate of the second metering pump 4 is set to 5g / min through the control system, so that the quinacrine dichloromethane solution and the hollow mesoporous silica powder are delivered to the mixer 1 according to the set ratio. The stirring device of the mixer 1 is turned on and the speed is kept at 800r / min to allow the materials to be fully mixed in the mixer 1 to form a mixture.

[0024] The fully mixed material is conveyed to the spiral conveyor adsorption tube 62, and the drive motor 61 is started to make the material convey forward at a uniform speed in the spiral conveyor adsorption tube 62 at a flow rate of 105g / min. At the same time, the heating device of the heating jacket is started to control the temperature in the spiral conveyor adsorption tube 62 at 20℃, so that the hollow mesoporous silica can fully adsorb the quinacrine nano-powder.

[0025] After adsorption, the material is conveyed from the outlet of the spiral conveyor adsorption tube 62 to the centrifuge 7 for solid-liquid separation. The waste liquid (dichloromethane) is recycled and reused. 102g of solid product is obtained. The content of quinacrine in the solid product is 50%, which is a quinacrine nano-material.
