[0023] Example

[0024] Reference Figure 1-4 This is an embodiment of the present invention, which provides a multi-spiral pulp thickener, comprising:

[0025] The components include a fixed frame 101, a drive assembly 102 adapted to be installed on the side surface of the fixed frame 101, an operating chamber 103 fixedly installed on the inner surface of the fixed frame 101, a feeding port 104 connected to the surface of the operating chamber 103, a discharge shell 105 fixedly connected to the bottom of the operating chamber 103, and an operating assembly 106 used in conjunction with the drive assembly 102.

[0026] The drive assembly 102 includes a fixed plate 102a fixedly mounted on the side surface of the fixed frame 101, a drive motor 102b adapted to be mounted on the surface of the fixed plate 102a, and a drive disk 102c fixedly mounted on the output end of the drive motor 102b.

[0027] The drive assembly 102 also includes a linkage disk 102d used in conjunction with the drive disk 102c, and a drive roller 102e fixedly installed in the center of the linkage disk 102d. The drive disk 102c and the linkage disk 102d are connected by a belt.

[0028] Specifically, after the drive motor 102b starts, it drives the drive disc 102c to rotate, and the linkage disc 102d rotates synchronously through belt transmission, thereby driving the central drive roller 102e to operate. After the pulp enters the operating chamber 103 from the feed port 104, the operating component 106 starts to work under the drive of the drive roller 102e, and stirs and concentrates the pulp through the multi-spiral structure. At the same time, the heating layer 103b of the operating chamber 103 provides a uniform heat source to promote water evaporation. The concentrated pulp is filtered and separated by the filter plate 106h, and finally the scraper 106d cleans up the residual material and guides it to the discharge shell 105 for discharge.

[0029] The operating chamber 103 includes an outer layer 103a, a heating layer 103b fixedly connected to the side wall of the outer layer 103a, a heat dissipation hole 103c fixedly installed on the inner surface of the heating layer 103b, and a contact layer 103d fixedly connected to the side surface of the heat dissipation hole 103c.

[0030] The operating component 106 includes a fixed disk 106a sleeved on the outer surface of the drive roller 102e, a mating plate 106b disposed on the side surface of the fixed disk 106a, a clamping plate 106c clamped to the side wall of the mating plate 106b, a scraper 106d rotatably connected to the end of the clamping plate 106c, and a fixed sleeve 106e fixedly installed on the side surface of the fixed disk 106a.

[0031] The operating assembly 106 also includes a roller 106f inserted into the center of the fixed sleeve 106e, a mating roller 106g used in conjunction with the roller 106f and fixedly connected to the side surface of the fixed disk 106a, and a filter plate 106h used in conjunction with the mating roller 106g.

[0032] Two rollers 106g are provided, and both rollers 106g are used in conjunction with the drum 106f. The scraper 106d is in contact with the filter plate 106h.

[0033] It should be noted that after the pulp enters the operating chamber 103 through the feeding port 104, the fixed disk 106a and the drum 106f begin to rotate synchronously under the drive roller 102e. The two cooperating rollers 106g and the drum 106f work together to squeeze and stir the pulp. At the same time, the heating layer 103b provides uniform heat through the heat dissipation holes 103c to promote water evaporation. During the concentration process, the filter plate 106h achieves solid-liquid separation, while the scraper 106d continuously scrapes off the concentrated pulp remaining on the surface of the filter plate 106h to prevent clogging. Finally, the concentrated pulp is discharged from the discharge shell 105 under the action of the screw propulsion, completing the efficient and continuous concentration operation and realizing the automated operation of heating, stirring, filtering and discharge.

[0034] In use, the drive motor 102b drives the drive roller 102e to rotate via belt drive, driving the fixed disk 106a and the roller 106f to operate synchronously. After the pulp enters the operating chamber 103 through the feed port 104, it achieves initial concentration under the synergistic squeezing and stirring action of the roller 106f and the two cooperating rollers 106g. At the same time, the heating layer 103b provides a uniform heat source through the heat dissipation holes 103c to accelerate the evaporation of water. During the concentration process, the filter plate 106h completes solid-liquid separation, and the scraper 106d cleans the surface of the filter plate 106h in real time to prevent clogging. Finally, the concentrated pulp is discharged through the discharge shell 105 under the action of the spiral propulsion.

[0035] In summary, its multi-spiral extrusion combined with dynamic filtration significantly improves concentration efficiency. The synergistic design of the heating layer 103b and heat dissipation holes 103c ensures uniform temperature distribution and effectively promotes moisture evaporation. The synergistic effect of the roller 106f and the double-cooperating roller 106g enhances the stirring and extrusion effect. Combined with the automatic scraper 106d system, it effectively prevents the filter plate 106h from clogging, ensuring continuous and stable operation. It realizes the integrated automatic operation of mechanical extrusion, heating evaporation and dynamic filtration in the pulp concentration process, improving production efficiency and concentration quality, while reducing energy consumption and maintenance costs.
