Description

Technical Field

[0001] The utility model relates to the technical field of polyacrylamide screening, in particular to a polyacrylamide fine screening device. Background Technique

[0002] Polyacrylamide is a polymer formed by polymerizing acrylamide monomers; polyacrylamide needs to be processed with good laboratory practice for pharmaceutical research to avoid toxicity, and polyacrylamide is often used as a raw material for reagents such as cosmetics, textiles, thickeners, and suspending agents. However, existing polyacrylamide screening devices have some deficiencies, such as:

[0003] For the polyacrylamide refinement screening machine with the application number CN202320074375.7, this device can improve the screening speed of the polyacrylamide refinement screening machine, thereby increasing the efficiency during the screening process of polyacrylamide. However, during use, it is difficult to perform fine screening on polyacrylamide, that is, to screen polyacrylamide with different particle sizes, which may lead to a problem of too large a difference in particle size during the screening of polyacrylamide.

[0004] Therefore, we propose a polyacrylamide fine screening device to solve the problems raised above. Content of the Utility Model

[0005] The purpose of the utility model is to provide a polyacrylamide fine screening device to solve the problem that most polyacrylamide screening devices on the current market are difficult to perform fine screening on polyacrylamide, that is, to screen polyacrylamide with different particle sizes, which may lead to a problem of too large a difference in particle size during the screening of polyacrylamide as proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A polyacrylamide fine screening device, including a device main body and a driving motor connected to the inside of the device main body.

And the bottom of the crushing mechanism is rotationally connected to the driving motor, and the crushing mechanism can work synchronously with the knocking mechanism.

[0008] By driving the motor to drive the crushing mechanism and the knocking mechanism to work, when the polyacrylamide raw material enters the feeding tank, the bonding particles can be crushed by the crushing mechanism. Subsequently, after the polyacrylamide raw material falls on the vibrating plate, the knocking mechanism will strike the bottom of the vibrating plate, causing the vibrating plate to vibrate continuously. As a result, the polyacrylamide raw material will fall from the filter screen, and the polyacrylamide raw material that does not fall from the filter screen will enter the feeding box under the drive of the slope of the vibrating plate. Thus, when the device performs fine screening work, polyacrylamide raw materials of different particle sizes can be screened out, increasing the accuracy and efficiency of the device during screening.

And two groups of feeding boxes are connected to the right end of the device main body, and the left end of the feeding box can be attached to the right end of the vibrating plate.

[0012] Adopting the above technical solution can make it more convenient for the device main body to receive polyacrylamide raw materials of different fineness, thereby increasing the efficiency of the device in collecting polyacrylamide raw materials.

[0022] Furthermore, through the setting of the feeding box, it can make it more convenient for the device main body to receive polyacrylamide raw materials with different fineness, thereby increasing the efficiency of the device in collecting polyacrylamide raw materials;

[0035] The driving motor 5 is fixedly connected to the rear end of the device main body 1.

[0037] Working principle: When using the polyacrylamide fine screening equipment, first connect the equipment power supply to the power grid for power supply. Then put the polyacrylamide raw material into the discharge chute 2. The driving motor 5 drives the crushing mechanism to crush the polyacrylamide raw material. Then the polyacrylamide raw material will fall on the top of the vibrating plate 10.

[0039] When the crushing mechanism is working, the driving motor 5 will drive the third sprocket 16 to rotate, so that the third sprocket 16 drives the fourth sprocket 18 to rotate through the second chain 17, and the fourth sprocket 18 drives the first gear 19 to rotate. Since the first gear 19 meshes with the second gear 20, the first gear 19 and the second gear 20 will drive the crushing shafts 21 to rotate towards each other at the same time, so that the two groups of crushing shafts 21 crush the polyacrylamide raw materials in the feeding trough 2, and the two groups of crushing shafts 21 crush the adhered polyacrylamide raw materials.
