Description

Technical Field

[0001] This utility model relates to the field of polyacrylamide production technology, and in particular to a polyacrylamide fine sieving machine. Background Technology

[0002] Polyacrylamide is a linear polymer that is a hard, glassy solid at room temperature. As a lubricant, suspending agent, clay stabilizer, oil displacement agent, fluid loss reducer, and thickener, polyacrylamide is widely used in drilling, acidizing, fracturing, water shut-off, cementing, and secondary and tertiary oil recovery. In China, the largest user is currently in the oil production sector, while the fastest growing sectors are water treatment and papermaking. During the production process, polyacrylamide materials need to be finely crushed and require the use of fine screening machines.

[0003] For example, Chinese utility model patent application number 202320074375.7 discloses a polyacrylamide fine screening machine, relating to the field of polyacrylamide production equipment. It includes a support platform, a vibration device on the support platform, a vibrating plate on the vibration device, a receiving box on the vibrating plate, a filter screen box on the receiving box, a connecting pipe on the outer wall of the filter screen box, the connecting pipe being connected to the filter screen box, and an outlet on the bottom wall of the end of the connecting pipe away from the filter screen box. This application has the effect of improving the screening speed of the polyacrylamide fine screening machine.

[0004] Although the aforementioned patent can increase the screening speed of polyacrylamide through vibration during use, the size of the polyacrylamide particles being screened is uneven. When the size of some polyacrylamide particles is small compared with the size of the screening holes, these particles are easily stuck inside the screening holes and are not easily separated from the screening holes by vibration, resulting in some screening holes being blocked and thus reducing the screening efficiency of the fine screening device.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1-4This utility model provides a polyacrylamide refining and screening machine, comprising a screening tank 1, a fixed plate 2 fixedly connected inside the screening tank 1, a plurality of screening holes 3 on the fixed plate 2, a fixed pipe 4 rotatably connected to the screening tank 1, a collection hopper 5 fixedly connected to the fixed pipe 4, a connecting pipe 6 fixedly connected to the fixed pipe 4, a plurality of nozzles 8 provided on the connecting pipe 6, the nozzles 8 being arranged perpendicularly to the collection hopper 5, a collection box 9 provided at the top of the fixed pipe 4, the fixed pipe 4 being connected to the collection box 9 through a rotating seal 15, a blower 10 fixedly installed on one side of the collection box 9, the output end of the blower 10 being fixedly connected to an annular frame 12 through an air supply pipe 11, the fixed pipe 4 rotating seal passing through the annular frame 12, one end of the connecting pipe 6 being located inside the annular frame 12, a drive motor 13 fixedly installed at the top of the screening tank 1, a connecting rod 14 fixedly connected to the output end of the drive motor 13, and a transmission assembly provided between the connecting rod 14 and the outer surface of the fixed pipe 4.

[0018] The collection box 9 is fixedly connected to the top of the screening tank 1. The inside of the collection box 9 is equipped with a filter plate 17 and a guide plate 18. A discharge port 23 is opened on one side of the collection box 9 and on the screening tank 1. A cover plate 24 is installed inside the discharge port 23. With the L-shaped collection box 9 and the filter plate 17, the filter plate 17 can intercept the polyacrylamide particles that are sucked into the collection box 9, preventing them from entering the blower 10 and damaging the blower 10. The intercepted polyacrylamide particles can fall to the bottom for easy collection after the blower 10 is turned off.

[0019] The transmission assembly includes two pulleys 19, which are fixedly sleeved on the outer surface of the fixed pipe 4 and the outer surface of the connecting rod 14, respectively. A belt 20 is connected between the outer surfaces of the two pulleys 19. The drive motor 13 is started through the control panel 22, which drives the connecting rod 14 and one of the pulleys 19 to rotate, thereby driving the fixed pipe 4, the connecting pipe 6, the collecting hopper 5 and several nozzles 8 to rotate synchronously. The rotating collecting hopper 5 can stir the polyacrylamide particles on the top of the fixed plate 2, thereby improving its screening speed.

[0020] The top of the screening tank 1 is provided with a feed inlet 21, the screening tank 1 is provided with a control panel 22, the bottom of the screening tank 1 is provided with a discharge pipe 16, and the discharge pipe 16 is provided with a solenoid valve 7.

[0021] Working principle: During operation, polyacrylamide granules are added into the screening tank 1 through the feed inlet 21 and fall to the top of the fixed plate 2. They are then screened by the screening holes 3 on the fixed plate 2. At the same time, the drive motor 13 can be started through the control panel 22, which drives the connecting rod 14 and one of the pulleys 19 to rotate. Under the transmission action of the belt 20, the other pulley 19 drives the fixed pipe 4, connecting pipe 6, collection hopper 5 and several nozzles 8 to rotate synchronously. The rotating collection hopper 5 can stir the polyacrylamide granules on the top of the fixed plate 2, thereby increasing the screening speed. When the drive motor 13 is started and the polyacrylamide particles are screened, the blower 10 can be started simultaneously through the control panel 22, so that its suction end generates suction. With the cooperation of the collection box 9 and the fixed pipe 4, the collection hopper 5 generates suction, while its air delivery end generates air. The air is then transported to the connecting pipe 6 through the air delivery pipe 11 and the annular pipe, and sprayed out by several nozzles 8. This blows the polyacrylamide particles stuck inside the screening hole 3 during the screening process out of the screening hole 3 and collects them in the suction-generating collection hopper 5. The air is then transported to the collection box 9 through the fixed pipe 4 for collection, preventing the particles from re-entering the screening hole 3 and clogging it. After the polyacrylamide particles added inside the screening tank 1 are screened, the solenoid valve 7 can be opened through the control panel 22 to discharge the screened polyacrylamide particles from the feed pipe 16. The polyacrylamide particles collected above the fixed plate 2 and inside the collection box 9 can be cleaned separately by opening the two cover plates 24 respectively.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
