Technical Field

[0001] The utility model relates to the technical field of polyacrylamide production, in particular to a polyacrylamide vibration screening and grinding device. Background Art

[0002] (PAM) polyacrylamide is a general term for acrylamide homopolymer or copolymerized with other monomers. (PAM) polyacrylamide is one of the most widely used water-soluble polymers. (PAM) polyacrylamide is widely used in oil extraction, papermaking, water treatment, textiles, medicine, agriculture and other industries.

[0003] In the production process of polyacrylamide, the polymer needs to be screened and then the screened polyacrylamide needs to be ground to ensure that its particle size meets specific requirements. The existing screening and grinding of polyacrylamide are mainly divided into two steps. The screening and grinding efficiency is low, which seriously affects the production efficiency of polyacrylamide.

[0004] Therefore, a polyacrylamide vibration screening and grinding device is proposed. Utility Model Content

[0037] Specifically, the utility model starts the vibrator 6 and the motor 11, and the motor 11 drives the first gear 12 to rotate. Since the first gear 12 and the second gear 13 are meshed, the first gear 12 will also drive the second gear 13 to rotate. Therefore, the first gear 12 will drive the first grinding wheel 15 to rotate, and the second gear 13 will drive the second grinding wheel 17 to rotate. Then, the polyacrylamide is poured into the inclined screen plate 4 through the feeding pipe 7. Under the action of the vibrator 6, the larger polyacrylamide will fall into the external material frame along the inclined direction of the inclined screen plate 4, and the finer polyacrylamide will fall between the first grinding wheel 15 and the second grinding wheel 17, and will be ground by the first grinding wheel 15 and the second grinding wheel 17 to form fine particles. Compared with the existing ones, the utility model integrates screening and grinding functions, improves the screening and grinding efficiency of polyacrylamide, and improves the production efficiency of polyacrylamide.

[0038] Embodiment 2:

[0039] See also Figure 1 , 35. The utility model provides a technical solution: a polyacrylamide vibration screening and grinding device, wherein the left and right outer walls of the frame 1 are both provided with a first clamping hole 19, and the outer wall of the receiving frame 18 is provided with a second clamping hole 20 that matches the first clamping hole 19; a fixing pin 21 is clamped in the first clamping hole 19 and the second clamping hole 20, and an auxiliary plate 22 is fixed to one end of the fixing pin 21; a compression spring 23 is provided on the outer wall of the fixing pin 21; one end of the compression spring 23 is fixed to the auxiliary plate 22, and the other end of the compression spring 23 is fixed to the outer wall of the frame 1.

[0040] Specifically, the fixing pin 21 is pulled by the auxiliary plate 22, and the compression spring 23 will perform a corresponding stretching movement. After one end of the fixing pin 21 is disengaged from the second clamping hole 20, the fixation of the docking material frame 18 can be released. Therefore, the utility model facilitates the disassembly of the docking material frame 18, thereby facilitating the packaging or production processing of the polyacrylamide inside the docking material frame 18, further improving the production and processing efficiency of polyacrylamide.

[0041] Working principle:

[0042] First, by starting the vibrator 6 and the motor 11, the motor 11 drives the first gear 12 to rotate. Since the first gear 12 and the second gear 13 are meshed, the first gear 12 will also drive the second gear 13 to rotate. Therefore, the first gear 12 will drive the first grinding wheel 15 to rotate, and the second gear 13 will drive the second grinding wheel 17 to rotate. Then, the polyacrylamide is poured onto the inclined screen plate 4 through the feed pipe 7. Under the action of the vibrator 6, the larger polyacrylamide will fall into the external material frame along the inclined direction of the inclined screen plate 4, and the finer polyacrylamide will fall between the first grinding wheel 15 and the second grinding wheel 17, and will be ground by the first grinding wheel 15 and the second grinding wheel 17 to form fine particles. Compared with the existing ones, the utility model integrates the screening and grinding functions, improves the screening and grinding efficiency of polyacrylamide, and improves the production efficiency of polyacrylamide.

[0043] Secondly, the fixing pin 21 is pulled by the auxiliary plate 22, and the compression spring 23 will perform a corresponding stretching movement. After one end of the fixing pin 21 is disengaged from the second clamping hole 20, the fixation of the docking material frame 18 can be released. Therefore, the utility model facilitates the disassembly of the docking material frame 18, thereby facilitating the packaging or production processing of the polyacrylamide inside the docking material frame 18, further improving the production and processing efficiency of polyacrylamide.
