Description

Technical Field

[0001] The utility model relates to the technical field of polyanionic cellulose production, in particular to a particle filtering device for polyanionic cellulose. Background Art

[0002] Polyanionic cellulose, referred to as PAC, is a water-soluble cellulose ether derivative obtained by chemically modifying natural cellulose. It is an important water-soluble cellulose ether, usually in the form of its sodium salt, and is widely used in oil drilling, especially in salt water wells and offshore oil drilling.

[0003] When producing polyanionic fibers, it is necessary to screen and filter the large particles of impurities mixed in the polyanionic fibers.

[0004] Chinese patent CN215354620U discloses a particle filtering device for polyanionic cellulose, which can save manpower and improve work efficiency; it includes a base, a restraining hinge, a screening frame, a motor, a reducer, a screening frame and a controller, a mounting plate is provided at the top of the base, a connecting block is provided at one end of the screening frame, the connecting block is hinged with the mounting plate through the restraining hinge, a transmission frame is provided at the other end of the screening frame, two groups of vertical plates are provided at the top of the base, the output end of the motor is connected to the input end of the reducer, an eccentric shaft is provided at the output end of the reducer, the eccentric shaft passes through the transmission frame and is rotatably mounted on the vertical plate, an eccentric block is provided on the eccentric, the screening frame is clamped in the screening frame, a support rod is provided at the top of the base, the controller is fixedly connected to the support rod, and the motor is electrically connected to the controller.

[0005] The above patent screens and filters the material through a screening frame during use. After the screening is completed, the screening frame is taken out to pour out the impurities left inside. However, in the actual screening and filtering process, there will be many impurities whose size is similar to the size of the screening mesh. During screening, the impurities will be stuck in the screening mesh and cannot be directly poured out, resulting in blockage. Therefore, in view of the above situation, it is urgently necessary to develop a polyanionic cellulose particle filtering device that is easy to clean the impurities stuck in the filter mesh and is not easy to be blocked, so as to overcome the shortcomings in current practical applications and meet current needs.
