Description

Technical Field

[0001] This utility model relates to the field of aluminum strip processing technology, and more specifically, it relates to an aluminum strip chemical polishing wastewater treatment and recycling equipment. Background Technology

[0002] The aluminum strip processing process generates a large amount of wastewater during cleaning, acid and alkali treatment, and other steps. The wastewater contains heavy metals and organic matter and needs to be treated before it can be discharged.

[0003] In conventional treatment processes, wastewater undergoing chemical reactions coagulates metals and organic matter, requiring sedimentation in a settling tank to achieve solid-liquid separation. However, sedimentation typically takes a long time and the settling tank is large, resulting in low efficiency of the sedimentation process. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a more efficient aluminum strip polishing wastewater treatment and recycling equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A wastewater treatment and recycling device for aluminum strip polishing includes a reaction vessel, which includes a second reaction tank arranged at an incline. A first reaction tank is located inside the second reaction tank. An inlet is located at the upward-facing end of the second reaction tank, extending into the first reaction tank. The upper half of the side wall of the second reaction tank is configured as a filter cartridge. A collection cylinder is attached to the outside of the second reaction tank, and a drain port is connected to the collection cylinder. A discharge port is connected to the top of the second reaction tank, and the other end of the discharge port is connected to a collection chamber. A collection box is movably installed within the collection chamber.

[0007] The present invention is further configured such that: a motor is installed on the downward-facing end of the reaction vessel two, the output shaft of the motor is connected to the reaction vessel one, the reaction vessel one is rotatably connected to the liquid inlet, a stirring impeller one is provided inside the reaction vessel one, the stirring impeller one is a spiral impeller, the stirring impeller one pushes the material upward, and several flow holes are opened on the end face of the reaction vessel one near the motor, the flow holes connecting the reaction vessel one and the reaction vessel two.

[0008] The present invention is further configured such that: the filter cylinder portion of the reaction tank two is a filtration zone, the lower half of the reaction tank two is a reaction zone, and a stirring impeller two and an extrusion impeller are provided on the outer wall of the reaction tank one. Both the stirring impeller two and the extrusion impeller are spiral impellers. The outer circles of both the stirring impeller two and the extrusion impeller are in contact with the inner wall of the reaction tank two. Both the stirring impeller two and the extrusion impeller push the material upward. The stirring impeller two is located in the reaction zone, and the extrusion impeller is located in the filtration zone.

[0009] The present invention is further configured such that: the extrusion impeller has a variable pitch structure, and the pitch of the portion of the extrusion impeller near the discharge port is reduced.

[0010] The present invention is further configured such that: a limiting ring is provided in the upper end face of the second reaction vessel, and a plurality of limiting end posts are uniformly provided in the lower end face of the second reaction vessel, and the first reaction vessel is rotatably connected to the limiting ring and the limiting end posts.

[0011] The advantages of this utility model are:

[0012] 1. Reaction tank one and reaction tank two are set along the inclined direction. Stirring impeller one and stirring impeller two are set in the two reaction tanks respectively. Stirring impeller one and stirring impeller two push the material upward, so that the material is fully stirred and contacted during the movement, ensuring the flocculation rate of the reactants.

[0013] 2. The upper part of the reaction tank is set as a filter cartridge structure. A variable pitch extrusion impeller is installed in the filtration section. The extrusion impeller has a small pitch on the side near the discharge port, which can squeeze the liquid in the material through the filter cartridge and collect it through the liquid collection cylinder. The solids in the material are squeezed and agglomerated by the extrusion impeller and discharged from the discharge port and collected. Thus, solid-liquid separation is achieved at the same time as flocculation reaction, replacing the large volume sedimentation tank and improving the wastewater treatment efficiency.

[0020] Please see Figure 1-2 The present invention provides the following technical solution:

[0021] A wastewater treatment and recycling device for aluminum strip polishing includes a reaction vessel 1, which includes a second reaction tank 12. The second reaction tank 12 is arranged at an inclination and contains a first reaction tank 11. The upper end of the second reaction tank 12 is provided with a liquid inlet 2, which extends into the first reaction tank 11. The upper half of the side wall of the second reaction tank 12 is configured as a filter cartridge. The outer side of the second reaction tank 12 is covered with a liquid collection cylinder 13, which is connected to a drain outlet 3. The top of the second reaction tank 12 is connected to a discharge outlet 15, and the other end of the discharge outlet 15 is connected to a collection chamber 16. A collection box 4 is movably installed in the collection chamber 16.

[0022] A motor 14 is installed on the downward-facing end of reaction vessel 12. The output shaft of the motor 14 is connected to reaction vessel 11. Reaction vessel 11 is rotatably connected to the liquid inlet 2. A stirring impeller 112 is installed inside reaction vessel 11. The stirring impeller 112 is a spiral impeller. The stirring impeller 112 pushes the material upward. Several flow holes 111 are opened on the end face of reaction vessel 11 near the motor 14. The flow holes 111 connect reaction vessel 11 and reaction vessel 12.

[0023] The filter section of reaction vessel 2 12 is the filtration zone 122, and the lower half of reaction vessel 2 12 is the reaction zone 121. The outer wall of reaction vessel 1 11 is equipped with a stirring impeller 2 123 and an extrusion impeller 124. Both stirring impeller 2 123 and extrusion impeller 124 are spiral impellers. The outer circles of stirring impeller 2 123 and extrusion impeller 124 are in contact with the inner wall of reaction vessel 2 12. Both stirring impeller 2 123 and extrusion impeller 124 push the material upward. Stirring impeller 2 123 is located in the reaction zone 121, and extrusion impeller 124 is located in the filtration zone 122.

[0024] The extrusion impeller 124 has a variable pitch structure. The pitch of the part of the extrusion impeller 124 near the discharge port 15 is reduced, forming a stacked screw structure, which can promote the agglomeration of extruded solids, fully extrude the liquid in the solids, and improve the solid-liquid separation effect.

[0025] A limiting ring 17 is provided in the upper end face of the reaction vessel 2 12, and a number of limiting end posts 18 are evenly arranged in the lower end face of the reaction vessel 2 12. The reaction vessel 11 is rotatably connected to the limiting ring 17 and the limiting end posts 18.

[0026] Specifically, reaction tank 11 and reaction tank 2 12 are arranged along the inclined direction. Stirring impeller 1 112 and stirring impeller 2 123 are respectively arranged in the two reaction tanks. Stirring impeller 1 112 and stirring impeller 2 123 both push the material upward, so that the material is fully stirred and contacted during the movement, ensuring the flocculation rate of the reactants.

[0027] The upper part of the reaction tank 12 is set as a filter cartridge structure. A variable pitch extrusion impeller 124 is set in the filtration section 122. The extrusion impeller 124 has a small pitch on the side near the discharge port 15, which can squeeze the liquid in the material through the filter cartridge and collect it through the liquid collection cylinder 13. The solids in the material are squeezed and agglomerated by the extrusion impeller 124 and discharged from the discharge port 15 and collected. Thus, solid-liquid separation is achieved at the same time as flocculation reaction, replacing the large volume sedimentation tank and improving the wastewater treatment efficiency.
