Technical Field

[0001] This utility model relates to the field of drying technology, and in particular to a high molecular weight polycarboxylate drying device. Background Technology

[0002] Polycarboxylate salts are a class of polymeric materials with excellent dispersibility, heat resistance, and chemical stability, and are commonly used in cement additives, detergents, and other fields. Their structure contains a large number of carboxylic acid groups, which endow them with good water solubility and ion exchange capacity.

[0003] The main purpose of drying high molecular weight polycarboxylate is to improve its storage stability and utilization efficiency. Drying can remove moisture from high molecular weight polycarboxylate, prevent product deterioration caused by microbial growth or hydrolysis, extend shelf life, and reduce moisture helps to reduce transportation costs and improve the physical properties of the product, such as enhanced fluidity and ease of measurement. For the preparation of high-performance concrete, dried polycarboxylate can be more evenly dispersed in the concrete, providing better water-reducing effect and workability.

[0018] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0019] A high-molecular-weight polycarboxylate drying device, such as Figures 1-4 As shown, the assembly includes a support frame 1, a drying drum 2, a first motor 3, a feeding cylinder 4, a cover plate 5, a discharge cylinder 6, a second solenoid valve 61, a heating element 9, a partition plate 10, a bulk material assembly, a first solenoid valve 41, a sealing ring 51, a vibrator 11, and a reinforcing base 12. There are two supports 1, with the drying drum 2 rotatably connected between them. The first motor 3 is installed on the side of each support 1 that is furthest from each other, and the output shaft of each first motor 3 is fixedly connected to the drying drum 2. The feeding cylinder 4 is fixedly connected to the top of the drying drum 2, and the cover plate 5 is hinged to the top of the feeding cylinder 4. The discharge cylinder 6 is connected to the bottom of the drying drum 2, and the second solenoid valve 61 is fixedly connected to the discharge cylinder 6. The heating element 9 is fixedly connected inside the drying drum 2. The drying drum 2 is further divided into left and right sections. Both sides are fixedly connected to isolation plates 10. Isolation plates 10 can prevent the high molecular weight polycarboxylate from adhering to the second motor 7 and vibrator 11 and causing damage. The isolation plates 10 are connected to the material dispersing components. The feeding cylinder 4 is fixedly connected to the first solenoid valve 41. The bottom of the cover plate 5 is fixedly connected to the sealing ring 51. The sealing ring 51 can enhance the sealing of the drying barrel 2 when drying the high molecular weight polycarboxylate and prevent hot air from escaping. The side of the left and right isolation plates 10 that is far apart from each other is fixedly connected to the vibrator 11. The two supports 1 are fixedly connected to the reinforcing base 12. The reinforcing base 12 can improve the rigidity and stability of this drying device, reduce the shaking or displacement of this drying device caused by mechanical movement, and ensure that this drying device operates smoothly.

[0020] like Figure 2 and Figure 3 As shown, the bulk material assembly includes a second motor 7 and a bulk material paddle 8. The second motor 7 is installed on the side of the left and right isolation plates 10 that are far apart from each other, and the bulk material paddle 8 is rotatably connected to the side of the left and right isolation plates 10 that are close to each other. The bulk material paddle 8 is fixedly connected to the output shaft of the second motor 7.

[0021] Initially, the cover plate 5, the first solenoid valve 41, and the second solenoid valve 61 are all closed. When drying the polycarboxylate, the cover plate 5 is rotated open, and then the first solenoid valve 41 is opened, allowing the polycarboxylate to be poured from the feeding cylinder 4 into the drying drum 2. The second motor 7 drives the dispersing paddle 8 to rotate, causing the polycarboxylate falling into the drying drum 2 to be dispersed by the impact of the dispersing paddle 8. The heating tube 9 heats the inside of the drying drum 2. The first solenoid valve 41 is then closed, and under the sealing action of the first solenoid valve 41, the second solenoid valve 61, and the drying drum 2, This system effectively reduces dust leakage caused by the drying and agitation of polycarboxylate, improves the working environment, reduces occupational disease risks, and protects employee health. The first motor 3 drives the drying drum 2 to rotate one revolution along its output shaft, and then the first motor 3 drives the drying drum 2 to rotate one revolution in the opposite direction along its output shaft. This rotational motion of the drying drum 2 ensures that the polycarboxylate is fully agitated and mixed within it, allowing for more uniform contact between the polycarboxylate and the hot air inside the drying drum 2. This accelerates the evaporation process of the polycarboxylate salt and improves the overall quality. The drying efficiency of the drying device is improved by the rotation of the drying drum 2, which effectively breaks down or prevents the formation of existing polycarboxylate agglomerates, ensuring that the polycarboxylate particles remain loose and facilitating rapid moisture release. The slurry 8 helps to quickly disperse newly added polycarboxylate, preventing localized accumulation upon entering the drying drum 2 and avoiding agglomeration caused by initial polycarboxylate aggregation. During the rotation of the drying drum 2, the vibrator 11 vibrates the isolation plate 10, which helps to prevent… To prevent polycarboxylate from adhering to the inner wall of the drying drum 2 or the partition plate 10, the inside of the drying device is kept clean, avoiding waste of polycarboxylate. After the polycarboxylate is dried, the first motor 3 drives the drying drum 2 to reverse and reset, opening the second solenoid valve 61. The dried polycarboxylate is discharged through the discharge cylinder 6. Under the action of the vibrator 11, the discharge of the dried polycarboxylate is accelerated. After the dried polycarboxylate is completely discharged, the second solenoid valve 61 is closed to prepare for the drying of the next batch of polycarboxylate.

These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way.
