Description

Technical Field

[0001] The utility model relates to the technical field of cellulose stirring, in particular to a polyanionic cellulose liquid stirrer. 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 using its sodium salt, which is widely used in oil drilling, especially salt water wells and offshore oil drilling. Polyanionic cellulose needs to be stirred during processing. The polyanionic cellulose stirring device generally uses a stirrer to stir in a closed space, so that the polyanionic cellulose is fully stirred before use. However, since polyanionic cellulose may have a certain viscosity during the stirring process, when mixing the raw materials, some of the raw materials will adhere to the inner wall of the mixer, which is inconvenient for the staff to clean the inner wall of the mixer, and the practicality is low.

[0003] The patent name is "A polyanionic cellulose liquid mixer" with the publication number "CN219376980U". The public document solves the above problems, but the device in the public document needs to combine the annular plate, the rotating plate and the arc plate with the mixer body so that the cleaning brush at the outer wall of the arc plate can clean the inner wall of the mixer body. Because the volume of the arc plate, the rotating plate and the annular plate is large, the difficulty of combining the arc plate, the rotating plate and the annular plate with the mixer body is increased, that is, the work intensity of the staff is increased, and the work efficiency of the staff is reduced. Based on this, the utility model designs a polyanionic cellulose liquid mixer to solve the above problems. Utility Model Content

Example 1

[0025] like Figure 1 , Figure 2 , Figure 5As shown, the device includes a base plate 1 and a cylinder 2, the cylinder 2 is fixedly arranged at the middle end of the top of the base plate 1, a cleaning component 3 is arranged on the top of the base plate 1, the cleaning component 3 includes a first motor 301 fixedly arranged on the left and right sides of the top of the base plate 1 and having forward and reverse rotation functions, the first motor 301 is connected to an external 220V power supply through a wire, a screw rod 302 is fixedly arranged on the top of the first motor 301, a scraper 303 is arranged on the upper end of the cylinder 2, the outer diameter of the scraper 303 is consistent with the inner diameter of the cylinder 2, the discharge hole 304 integrally arranged inside the scraper 303 is a through hole design, and mounting plates 305 with an L-shaped cross-section are fixedly arranged on the left and right sides of the top of the scraper 303, and one end of the mounting plate 305 away from the scraper 303 is threadedly sleeved on the outside of the screw rod 302.

[0026] When the staff needs to clean the inner wall of the cylinder 2, the staff turns on the forward rotation function of the first motor 301, and the first motor 301 drives the screw rod 302 to rotate. Through the threaded transmission between the screw rod 302 and the mounting plate 305, the mounting plate 305 drives the scraper 303 to move downward along the direction of the cylinder 2, so that the scraper 303 scrapes off the raw materials adhered to the inside and outside of the cylinder 2. After scraping, the reverse function of the first motor 301 is turned on to move the scraper 303 out of the cylinder 2, so that the staff can remove the raw materials adhered to the scraper 303. Example 2

[0027] like Figure 2 , Figure 3 , Figure 4 As shown, a second motor 4 is fixedly provided on the middle side of the bottom end of the cylinder 2, and the second motor 4 is connected to an external 220V power supply through a wire. A rotating shaft 5 is fixedly provided on the top of the second motor 4, and the end of the rotating shaft 5 away from the second motor 4 rotates and penetrates the cylinder 2, and the axis of the rotating shaft 5 is coaxial with the axis of the discharge hole 304. Stirring rods 6 are fixedly provided on the left and right sides of the upper end of the outside of the rotating shaft 5, and the two stirring rods 6 are mirror-distributed with the axis of the rotating shaft 5. A scraper 7 is fixedly provided at the bottom of the stirring rod 6, and the bottom of the scraper 7 is in a design of mutual fit with the bottom surface of the cylinder 2. A slide groove 8 is integrally provided inside the scraper bar 7, and a wedge-shaped strip 9 is slidably connected inside the slide groove 8, and the bottom of the wedge-shaped strip 9 is in a design of mutual fit with the bottom surface of the cylinder 2.

[0028] According to the operation method in Example 1, when the scraper 303 moves downward along the barrel 2, the scraper 303 applies an extrusion force to the inclined surface of the wedge strip 9, so that the wedge strip 9 moves into the chute 8, and the spring 10 is deformed, ensuring the cleaning effect of the scraper 303 on the lower end of the inner wall of the barrel 2. When the scraper 303 moves upward, the wedge strip 9 is reset by the rebound force of the spring 10. When the raw materials adhered to the inside of the barrel 2 are cleaned, the staff first turns off the first motor 301, and then turns on the second motor 4. The second motor 4 drives the rotating shaft 5 to drive the stirring rod 6 together with the scraper strip 7 and the wedge strip 9 to adhere to the inside of the barrel 2 The raw materials on the bottom surface of the cylinder 2 are scraped off. After scraping, the second motor 4 is turned off, and the stirring rod 6 is separated from the rotating shaft 5, so that the staff can remove the raw materials adhering to the stirring rod 6, the scraping strip 7 and the outer wall of the wedge strip 9. When the raw materials need to be processed, the staff first installs the small-volume stirring rod 6 together with the scraping strip 7 and the wedge strip 9 and the rotating shaft 5, and then pours the raw materials to be processed into the cylinder 2 through the discharge hole 304, and then turns on the second motor 4. The second motor 4 drives the rotating shaft 5 to drive the stirring rod 6 to stir the raw materials. After stirring, the valve 12 is opened to discharge the processed raw materials from the discharge pipe 11.
