Technical Field
[0001] The utility model relates to the technical field of conveying devices, in particular to a conveying device for producing polyacrylamide. Background Art
[0002] Polyacrylamide is a general term for polymers obtained by copolymerization of acrylamide homopolymers or other monomers. It is one of the most widely used varieties of water-soluble polymers. Since the structural unit of polyacrylamide contains amide groups and is easy to form hydrogen bonds, it has good water solubility and high chemical activity. It is widely used in industries such as oil extraction, water treatment, textiles, papermaking, mineral processing, medicine, and agriculture.
[0003] In the production process of polyacrylamide, it needs to be transported between different processes, so a production conveying device is needed. The conveying devices in the prior art are mostly provided with storage containers for storing the semi-finished polyacrylamide to be transported. However, polyacrylamide has a certain viscosity and will stick to the inner wall of the container during storage, resulting in a certain loss in the polyacrylamide transportation process, causing a certain amount of waste. Utility Model Content
[0004] In order to reduce loss and waste during the transportation process, the present application provides a transportation device for polyacrylamide production.
[0005] The present application provides a conveying device for polyacrylamide production using the following technical solution:
[0006] A conveying device for polyacrylamide production comprises a conveying vehicle and a storage tank arranged on the conveying vehicle, wherein the storage tank is provided with a discharge valve and a feeding port, the storage tank is provided with a driving member, a scraper in contact with the inner wall of the storage tank is provided in the storage tank, the scraper is provided with a connecting rod, the connecting rod connects the scraper and the driving member, and the driving member is used to drive the scraper to move in the storage tank.
[0007] By adopting the above technical scheme, polyacrylamide or semi-finished products are added into the storage tank through the feeding port, and the conveying vehicle is pushed to move for conveying. When conveyed to the next process, the discharge valve is opened to put the polyacrylamide or semi-finished products into the container of the next process to complete the conveying. During this process, the driving part can be started to drive the scraper to move in the storage tank, thereby scraping off the polyacrylamide or semi-finished products stuck on the inner wall of the storage tank, thereby reducing the loss caused by the polyacrylamide or semi-finished products sticking to the inner wall of the storage tank, and reducing the loss and waste of polyacrylamide or semi-finished products during transportation.
