Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyaluminum chloride production and processing technology, specifically to a polyaluminum chloride production waste residue recycling device. Background Technology
[0002] Polyaluminum chloride is made from a mixture of raw materials such as bauxite, calcium aluminate powder and hydrochloric acid. During the production of polyaluminum chloride, the raw materials themselves contain certain impurities, which results in waste residue in the polyaluminum chloride obtained after the reaction. The waste residue is a viscous, gel-like, yellowish-brown substance that is weakly acidic. It is usually disposed of by landfill.
[0003] However, directly landfilling polyaluminum chloride (PAC) waste is not environmentally friendly and makes it inconvenient to reuse it. Therefore, the waste needs to be treated before it can be utilized. In the process of treating the waste, an alkaline liquid is usually added to neutralize it. After the neutralization reaction, the mud colloid can be transformed into a neutral, non-toxic, and non-polluting waste that can be used as a raw material for brick and stone production or as a building material. However, it is now difficult to fully mix the waste with the alkaline liquid, which reduces the effectiveness of the recycling and treatment of PAC waste. Utility Model Content

To achieve the aforementioned goal of facilitating full mixing of alkaline liquid and polyaluminum chloride waste residue during neutralization, this utility model provides the following technical solution: A waste residue recovery device for polyaluminum chloride production includes a recovery cylinder. A top cover is bolted to the top of the recovery cylinder. A booster pump is fixed to the middle of the upper surface of the top cover.

An adapter cylinder is fixed to the bottom end of the vertical guide tube, and a horizontal guide tube is rotatably connected to the side of the adapter cylinder. An internal gear plate is fixed to the surface of the horizontal guide tube and inside the octagonal cylinder.
[0006] Preferably, the toothed ring meshes with the inner toothed disc, and one end of the transverse guide tube passes through the adapter cylinder and is rotatably connected to the adapter cylinder.

[0011] Compared with the prior art, this utility model provides a device for recycling waste residue from polyaluminum chloride production, which has the following beneficial effects:
[0012] 1. This polyaluminum chloride production waste residue recycling device can drive the toothed ring to rotate when the internal motor is started. The toothed ring can drive the pressure roller to rotate by meshing with the internal toothed disc. Therefore, the waste residue can be crushed and pulverized by the rotation of the pressure roller.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Please see Figure 1-5 This utility model provides a waste residue recycling device for polyaluminum chloride production, including a recycling cylinder 1. A top cover 2 is fixed to the top of the recycling cylinder 1 by bolts. A booster pump 3 is fixed to the middle of the upper end face of the top cover 2. A liquid injection pipe 4 is fixed to the end face of the booster pump 3. A feeding pipe 5 is fixed to the outer side of the upper end face of the top cover 2. A collection cylinder 6 is fixed to the bottom surface of the recycling cylinder 1. A support foot 7 is fixed to the surface of the collection cylinder 6. A discharge pipe 8 is fixed to the outer side of the bottom surface of the collection cylinder 6. A filter hole 9 is opened on the inner bottom surface of the recycling cylinder 1. An external motor 10 is fixed to the inner side of the bottom surface of the collection cylinder 6. An octagonal cylinder 11 is fixed to the output end of the external motor 10. A pressure roller 12 rotates on the outer side of the octagonal cylinder 11.
[0022] A vertical guide tube 13 is fixed to the upper end face of the octagonal cylinder 11, and the top end of the vertical guide tube 13 is rotatably connected to the booster pump 3. A side cavity 14 is opened inside the recovery cylinder 1, and a rack 15 is fixed to the bottom surface of the inside of the side cavity 14. A side rotating ring 16 is rotatably connected to the port of the side cavity 14. The rack 15 meshes with an external gear disc 17. A through hole 18 is opened on the surface of the pressure roller 12, and a nozzle 19 is fixed inside the through hole 18. An internal motor 20 is fixed to the bottom surface of the inside of the octagonal cylinder 11, and the output end of the internal motor 20 is... A toothed ring 21 is fixed, and an adapter cylinder 22 is fixed at the bottom of the vertical guide tube 13. A horizontal guide tube 23 is rotatably connected to the side of the adapter cylinder 22. An internal toothed disc 24 is fixed on the surface of the horizontal guide tube 23 and inside the octagonal cylinder 11. Waste residue can be added to the recycling cylinder 1 through the feeding pipe 5. At the same time, the external motor 10 can be started to drive the octagonal cylinder 11 to rotate. In turn, the octagonal cylinder 11 can drive the pressure roller 12 to rotate along the circumference of the recycling cylinder 1, so that the pressure roller 12 can crush and pulverize the waste residue in the circumferential direction.
[0023] Furthermore, the toothed ring 21 meshes with the inner toothed disc 24, and one end of the inner side of the transverse guide tube 23 passes through the adapter cylinder 22 and is rotatably connected to the adapter cylinder 22. When the inner motor 20 rotates, it can drive the toothed ring 21 to rotate. And the toothed ring 21, through meshing with the inner toothed disc 24, can drive the transverse guide tube 23 to rotate the pressure roller 12 so that the pressure roller 12 can rotate and crush the waste residue.
[0024] Furthermore, one end of the outer side of the horizontal guide tube 23 extends into the interior of the pressure roller 12 and is fixedly connected to the pressure roller 12. The nozzle 19 is connected to the horizontal guide tube 23 through the guide tube, so that the booster pump 3 can transport the alkaline liquid to the nozzle 19 through the vertical guide tube 13, the adapter tube 22, and the horizontal guide tube 23, and spray the alkaline liquid out through the nozzle 19 to neutralize the waste residue.
[0025] Furthermore, multiple sets of pressure rollers 12 are arranged along the circumference of the recovery cylinder 1, and multiple sets of nozzles 19 are arranged along the circumference and axial direction of the pressure rollers 12. The surface of the pressure rollers 12 is provided with spiral strips, and the spiral directions of adjacent sets of spiral strips are opposite, as shown in the attached instruction manual. Figure 2 As shown, when the pressure roller 12 rotates, the waste residue can be dispersed through the spiral strips on its surface so that the pressure roller 12 can evenly crush and pulverize the waste residue.
[0026] Furthermore, the outer gear disc 17 is fixedly connected to one outer end of the pressure roller 12 via a rotating shaft, and the rotating shaft passes through the side rotating ring 16 and is rotatably connected to it. When the pressure roller 12 rotates along the circumference of the recycling cylinder 1, it can drive the side rotating ring 16 to rotate as well. When the pressure roller 12 rotates and crushes the waste residue, the outer gear disc 17 can support the rotation of one outer end of the pressure roller 12 through the meshing of the rack 15, so that the pressure roller 12 can rotate stably and crush the waste residue.
[0027] Furthermore, the filter hole 9 is located above the collecting cylinder 6, and the bottom surface of the collecting cylinder 6 is inclined. The crushed and neutralized waste residue can enter the collecting cylinder 6 through the filter hole 9. Because the bottom surface of the collecting cylinder 6 is inclined, the waste residue is concentrated at the port of the discharge pipe 8 so that the discharge pipe 8 can discharge the waste residue.
[0028] In use, waste residue can be added to the recycling cylinder 1 through the feeding pipe 5. Simultaneously, starting the external motor 10 drives the octagonal cylinder 11 to rotate, which in turn drives the pressure roller 12 to rotate along the circumference of the recycling cylinder 1. This allows the pressure roller 12 to crush and pulverize the waste residue circumferentially. Simultaneously, starting the internal motor 20 drives the toothed ring 21 to rotate. The toothed ring 21, through meshing with the internal toothed disc 24, causes the transverse guide tube 23 to drive the pressure roller 12 to rotate. Therefore, the rotation of the pressure roller 12 also crushes and pulverizes the waste residue. Furthermore, the rotation of the spiral strips on the surface of the pressure roller 12 drives the waste residue radially inward or outward along the recycling cylinder 1. The side dispersion allows the pressure roller 12 to more thoroughly and fully crush the waste residue. During the crushing process of the pressure roller 12, the injection pipe 4 is connected to the external alkaline liquid. Therefore, the booster pump 3 can deliver alkaline liquid into the nozzle 19 through the vertical pipe 13, the adapter cylinder 22, and the horizontal pipe 23 and spray it out to mix with the waste residue. When the pressure roller 12 drives the nozzle 19 to rotate, the nozzle 19 can spray alkaline liquid at different angles to different positions of the waste residue, so that the alkaline liquid can be more evenly and fully mixed and neutralized with the waste residue, thereby improving the neutralization effect of the polyaluminum chloride production waste residue and alkaline liquid.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
