Description

Technical Field

[0001] The utility model relates to the technical field of chemical reagent preparation, in particular to a low-concentration colloidal palladium stirring device. Background Art

[0002] Colloidal palladium is a solution prepared by mixing divalent tin and palladium salts. Using colloidal palladium to activate the plastic surface is one of the key steps in the plastic surface treatment process. In the prior art, a colloidal palladium preparation device described in Patent No. CN201520504788.X uses a blender to stir the raw materials, replacing manual labor and saving labor. The raw materials react at a constant temperature and the exhaust gas generated during the reaction is filtered and treated. However, the raw materials are not stirred well during the stirring process, and some of the raw materials will adhere to the inner wall of the blender, resulting in insufficient stirring of the raw materials. The device occupies a large area, is cumbersome to operate, and is inflexible to use. Utility Model Content

[0022] like Figures 1 to 3 As shown, during actual use of the present invention, the operator pours a low-concentration colloidal palladium solution into the reactor 21, and then starts the drive motor 31, and transmits power to the driven wheel 33 through the drive wheel 32 and the transmission belt 34. The rotation of the driven wheel 33 drives the stirring shaft 221 to rotate, and then drives the stirring blade 222 and the scraper 223 to perform stirring and scraping operations to improve the mixing efficiency between the raw materials. The outer side of the scraper 223 is against the inner wall of the reactor 21. During the stirring process, the inner wall of the reactor 21 is continuously scraped to prevent some raw materials from adhering to the inner wall of the reactor 21, resulting in incomplete mixing and affecting the quality of the finished product. At the same time, during the stirring process, the exhaust gas recovery mechanism 6 collects and processes the exhaust gas generated to reduce environmental pollution.

[0023] As a further preferred embodiment, a circulation mechanism 4 is provided on the side wall of the reactor 21, and the circulation mechanism 4 includes a circulation pipe 41 provided at the upper and lower ends of the reactor 21 and a circulation pump 42 provided on the circulation pipe 41, and both ends of the circulation pipe 41 are connected to the side wall of the reactor 21.

[0024] Specifically, during use, the circulation pump 42 pumps the mixed liquid at the bottom of the reactor 21 to the top of the reactor 21 through the circulation pipe 41 to realize the circulation of the mixed liquid and avoid partial deposition of raw materials at the bottom of the reactor 21 resulting in incomplete mixing.

[0025] As a further preferred embodiment, a constant temperature mechanism 5 is provided outside the reactor 21 , and the constant temperature mechanism 5 includes a heat preservation layer 51 sleeved outside the reactor 21 and a constant temperature tube 52 provided between the heat preservation layer 51 and the reactor 21 .

[0026] Specifically, the reactor 21 is heated by injecting a heat medium into the thermostatic tube 52 , so that the equipment maintains a constant temperature during the reaction process, thereby improving the stirring and mixing effect.

[0027] As a further preferred embodiment, the tail gas recovery mechanism 3 includes a tail gas pipe 61 fixedly arranged at the upper end of the reactor 21 and an activated carbon purification box 62 arranged at the end of the tail gas pipe 61 .

[0028] Specifically, the acidic waste gas generated during the reaction is transported from the reactor 1 to the activated carbon purification box 62 for absorption through the suction pump and the tail gas pipe 61. Preferably, an alkaline solution can be poured into the activated carbon purification box 62 in advance. The alkaline solution can be hot potassium carbonate or ethanolamine. The acidic waste gas contacts and reacts with the alkaline solution to achieve the effect of absorption and removal. Thereafter, the tail gas is discharged to the external environment through the activated carbon plate to achieve tail gas purification.
