Description

Technical Field

[0001] This invention relates to the field of alkali recovery, and more specifically, to an alkali recovery device for waste liquid from aluminum profile molds. Background Technology

[0002] In profile manufacturing plants, the recovery of alkaline solutions from aluminum-containing waste liquid is generally carried out using the crystallization method. The crystallization method involves adding aluminum hydroxide powder to the alkaline solution containing aluminum to be recovered, using the aluminum hydroxide powder as seed crystals. Through a series of controls on temperature, concentration, and the ratio of sodium hydroxide to aluminum concentration, as well as stirring, the sodium aluminate in the solution undergoes a chemical reaction, precipitating aluminum hydroxide and generating sodium hydroxide, thereby achieving the purpose of reducing the aluminum concentration and recovering the alkali.

[0003] Currently, when using crystallization for alkali recovery, the required materials are mostly transported into the reactor for mixing. However, most existing reactors use a single stirring shaft to mix multiple materials, which can easily lead to uneven mixing and affect subsequent alkali recovery. Summary of the Invention

[0004] This invention provides an alkali recovery device for aluminum profile mold waste liquid, which solves the above-mentioned technical problems in related technologies.

[0006] Furthermore: the stirring assembly includes a sleeve, a drive shaft is arranged inside the sleeve, the length direction of the sleeve is consistent with the axial direction of the drive shaft, a retaining ring is installed at the top of the sleeve, and a transmission component is installed inside the retaining ring, the transmission component is used to drive the drive shaft and the sleeve to rotate in opposite directions.

[0007] Furthermore: the retaining ring is fixedly connected to the sleeve by several connecting blocks, and an opening is provided between the connecting blocks.

[0008] Furthermore: the transmission components include gear A and gear B. Gear A is sleeved on the outer wall of the transmission shaft, and gear B is rotatably connected to the inner wall of the reactor. Gear A and gear B mesh with each other. A toothed ring is installed on the inner wall of the fixed ring, and gear B meshes with the toothed ring.

[0009] Furthermore: the feeding assembly includes a spiral blade, which is arranged inside the sleeve and fixedly connected to the drive shaft. The outer wall of the sleeve has a threaded groove and a slider is fitted on it. The slider engages with the sleeve through the threaded groove. A connecting rod is installed on the outer wall of the slider. A scraper ring is installed at the end of the connecting rod away from the slider. The cross-section of the scraper ring is triangular, and the outer wall of the scraper ring is in contact with the inner wall of the reactor.

[0010] Furthermore, the interior of the reactor is provided with a sliding groove, the groove direction of which is consistent with the height direction of the reactor. The outer wall of the scraper ring is equipped with a protrusion, which is arranged inside the sliding groove. The protrusion and the sliding groove form a sliding guide fit.

[0011] Furthermore, the feeding assembly also includes a feeding component and a linkage component. The linkage component is connected to the scraper ring, and the feeding component cooperates with the linkage component.

[0014] Furthermore: the linkage includes a connecting rod, one end of which is rotatably connected to the outer wall of the scraper ring, and the other end is rotatably connected to the feeding plate.

[0015] The beneficial effects of this invention are as follows: During use, when the drive shaft drives the transmission shaft to rotate, the spiral blades first transport the material at the bottom of the reactor to the top, further improving the mixing effect of waste liquid and additives. The scraper ring descends with the rotation of the sleeve. The descent of the scraper ring can not only push the waste liquid at the top of the reactor to the bottom, but also scrape off the viscous material attached to the inner wall of the reactor, thus facilitating the cleaning of the inner wall of the reactor after the waste liquid is discharged.

[0021] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed merely to enable those skilled in the art to better understand and implement the subject matter described herein. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples. Example 1

[0022] like Figures 1-4 As shown, an alkali recovery device for waste liquid from aluminum profile molds includes a vertically arranged reactor 1. A feeding mechanism 2 is installed on one side of the reactor 1 and is connected to the reactor 1. A drive shaft 12 is installed inside the reactor 1, with the axial direction of the drive shaft 12 aligned with the height direction of the reactor 1. A drive shaft 11 is installed at one end of the drive shaft 12, with the axis of the drive shaft 11 aligned with the axis of the drive shaft 12. A stirring assembly 13 and a feeding assembly 14 are installed inside the reactor 1. The stirring assembly 13 is connected to the drive shaft 12 and cooperates with the feeding assembly 14. The feeding assembly 14 is used to send the waste liquid at the bottom of the reactor 1 to the top and to push the outer layer of waste liquid to the center of the reactor 1.

[0023] The stirring assembly 13 includes a sleeve 131, a drive shaft 12 is arranged inside the sleeve 131, the length direction of the sleeve 131 is consistent with the axial direction of the drive shaft 12, a fixing ring 132 is installed on the top of the sleeve 131, and a transmission component 134 is installed inside the fixing ring 132. The transmission component 134 is used to drive the drive shaft 12 and the sleeve 131 to rotate in opposite directions.

[0024] The fixing ring 132 is fixedly connected to the sleeve 131 by a number of connecting blocks 133, and an opening is provided between the connecting blocks 133.

[0025] The transmission component 134 includes gear A 1341 and gear B 1342. Gear A 1341 is sleeved on the outer wall of the transmission shaft 12, and gear B 1342 is rotatably connected to the inner wall of the reactor 1. Gear A 1341 and gear B 1342 mesh. A gear ring 1343 is installed on the inner wall of the fixing ring 132, and gear B 1342 meshes with gear ring 1343.

[0026] The feeding assembly 14 includes a spiral blade 141, which is arranged inside the sleeve 131 and fixedly connected to the drive shaft 12. The outer wall of the sleeve 131 is provided with a threaded groove and a slider 142 is sleeved thereon. The slider 142 engages with the sleeve 131 through the threaded groove. A connecting rod 143 is installed on the outer wall of the slider 142. A scraper ring 144 is installed at the end of the connecting rod 143 away from the slider 142. The cross-section of the scraper ring 144 is triangular, and the outer wall of the scraper ring 144 is attached to the inner wall of the reactor 1.

[0027] The interior of the reactor 1 is provided with a sliding groove, the groove direction is consistent with the height direction of the reactor 1, and the outer wall of the scraper ring 144 is equipped with a protrusion, which is arranged inside the sliding groove. The protrusion and the sliding groove form a sliding guide fit.

[0028] The feeding assembly 14 also includes a feeding component 145 and a linkage component 146. The linkage component 146 is connected to the scraper ring 144, and the feeding component 145 cooperates with the linkage component 146. The linkage component 146 is used to drive the feeding component 145 to reciprocate during the lifting and lowering of the scraper ring 144.

[0029] The material feeding component 145 includes a support rod 1451 and a material feeding plate 1452. A rotating ring is engaged with the outer wall of the sleeve 131. One end of the support rod 1451 is fixedly connected to the rotating ring. The top of the material feeding plate 1452 is rotatably connected to the other end of the support rod 1451. The linkage component 146 is connected to the material feeding plate 1452.

[0030] The vertical section of the feed plate 1452 has an arc-shaped plate structure, and the cross section has an L-shaped structure.

[0031] The linkage 146 includes a connecting rod 1461, one end of which is rotatably connected to the outer wall of the scraper ring 144, and the other end is rotatably connected to the material feeding plate 1452.

[0032] In the process of using the alkali recovery device of the present invention, the mold waste liquid is first fed into the reactor 1 from the top inlet, and the required chemical agent is delivered into the reactor 1 through the delivery mechanism 2. The delivery mechanism 2 is the prior art and will not be described in detail here. Then, the alkali in the waste liquid (containing aluminum alkali liquid) is recovered in the reactor 1 by crystallization method. During the recovery process, the stirring component 13 in the reactor 1 continuously stirs the waste liquid.

[0033] During the stirring process, the drive shaft 11 drives one end of the transmission shaft 12 to rotate. The transmission shaft 12 drives the bottom spiral blade 141 to rotate. At the same time, the transmission shaft 12 drives the B gear 1342 to rotate through the A gear 1341 group. The B gear 1342 meshes with the toothed ring 1343 in the fixing ring 132. Therefore, the rotation of the B gear 1342 drives the fixing ring 132 at the top of the sleeve to rotate, and drives the sleeve to rotate, so that the sleeve and the spiral blade 141 rotate in opposite directions. At this time, the spiral blade 141 will transport the waste liquid at the bottom of the reactor 1 to the inside of the sleeve 131. The waste liquid flows in the sleeve 131 and flows out from its top, thereby transporting the bottom material of the reactor 1 to the top, further improving the mixing effect of the waste liquid and the additives.

[0034] It should be noted that the drive shaft 11 is driven by a motor, a rotary cylinder, or other drive devices.

[0035] Secondly, the rotation of the sleeve 131 drives the slider 142 to descend along its length, and through the connecting rod 143 drives the scraper ring 144 to descend along the inner wall of the reactor 1. Since the bottom of the scraper ring 144 is in contact with the inner wall of the reactor 1, the descent of the scraper ring 144 can not only push the waste liquid at the top of the reactor 1 to the bottom, but also scrape off the viscous substances attached to the inner wall of the reactor 1, thus facilitating the cleaning of the inner wall of the reactor 1 after the waste liquid is discharged.

[0036] Simultaneously, the descent of the scraper ring 144 drives the connecting rod 1461 on its outer wall to descend. Since one end of the connecting rod 1461 follows the descent of the scraper ring 144 and the other end is connected to the material-pushing plate 1452, as one end of the connecting rod 1461 descends and continuously approaches the other end, the connecting rod 1461 gradually changes from a vertical state to a horizontal state, and pushes the material-pushing plate 1452 inward through the other end. The movement of the material-pushing plate 1452 can accelerate the entry of the outer layer material into the sleeve 131, realizing the rapid entry of the outer layer material into the inner layer. As the scraper ring 144 continues to descend, the connecting rod 1461 rotates from a horizontal state to a downward vertical state, at which point the material-pushing plate 1452 resets. At the same time, when the scraper ring 144 rises, the connecting rod 1461 rotates from a vertical state to a horizontal state, and after rotating back to a vertical state, the material-pushing plate 1452 moves again. This process is repeated, thus continuously achieving the mixing and stirring of the material.

[0037] The embodiments of this embodiment have been described above with reference to the accompanying drawings. However, this embodiment is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this embodiment without departing from the spirit of this embodiment and the scope of protection of the claims, and all of these forms are within the protection scope of this embodiment.
