Technical Field
[0001] This utility model relates to the field of waste acid treatment technology, specifically a cold-drawn wire waste acid recycling and regeneration treatment device. Background Technology
[0002] Cold-drawn wire typically refers to the process of drawing metal materials into fine wires at room temperature. During this process, acid pickling is used to remove surface oxides or impurities. To reduce waste acid emissions and lower production costs, waste acid needs to be recycled and regenerated. Impurities and metal ions are removed from the used acid solution so that it can be reused in production.
[0003] In existing waste acid treatment methods, alkaline substances need to be injected into the mixing chamber to neutralize the waste acid. The neutralized waste acid is then discharged to a filtration device for filtration to remove metal ions and impurities. However, when the neutralized waste acid is discharged through pipes, impurities and metal ions tend to remain inside the pipes, making cleaning difficult. Furthermore, the filtration device occupies a large area and is not convenient for directly filtering metal ions and impurities inside the mixing chamber. Utility Model Content
[0004] The purpose of this invention is to provide a cold-drawn waste acid recycling and regeneration treatment device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A cold-drawn wire waste acid recycling and regeneration treatment device includes:
[0007] Mixing bin;
[0008] A filter assembly is movably disposed inside the mixing chamber, the filter assembly including a filter screen slidably connected inside the mixing chamber;
[0009] A stirring assembly is movably disposed inside a stirring chamber. The stirring assembly includes a hollow rotating shaft rotatably connected inside the stirring chamber. Multiple arc-shaped air struts are fixedly embedded in the lower end of the hollow rotating shaft. One end of each arc-shaped air strut is fixedly connected to a stirring rod. An arc-shaped stirring frame is fixedly installed on the outer surface of the hollow rotating shaft.
[0010] The air pump assembly is fixedly installed at the top of the mixing chamber.
[0011] Furthermore, multiple collection chambers are fixedly embedded at equal angles on the outer surface of the mixing chamber, and a blocking block is movably embedded at the upper end of each collection chamber.
[0012] Furthermore, the inner surface of the mixing chamber is provided with multiple sliding grooves at equal angles. A first sliding rod, which is fixedly connected to the filter screen, is slidably connected inside the sliding groove and slides through the mixing chamber. A connecting frame is fixedly connected to the upper end of the first sliding rod. A first electric push rod, which can drive the connecting frame to move up and down, is symmetrically fixedly installed on the outer surface of the collection chamber.
[0013] Furthermore, a collar is movably embedded in the upper end of the mixing chamber, a bearing is fixedly installed on the inner surface of the collar, the hollow rotating shaft passes through the bearing and is fixedly connected to the inner ring of the bearing, and a second sliding rod that slides through the collar is fixedly installed on the upper surface of the mixing chamber.
[0014] Preferably, the upper surface of the mixing chamber is fixedly mounted with a second electric push rod that can drive the collar to move up and down via a bracket. The upper surface of the collar is fixedly mounted with a motor via a bracket. The output end of the motor and the upper part of the outer surface of the hollow rotating shaft are fixedly mounted with two meshing gears.
[0015] Furthermore, the pumping assembly includes:
[0016] An air pump is fixedly installed on the upper surface of the mixing chamber.
[0017] The connecting tube is fixedly installed on the inner surface of the hollow rotating shaft;
[0018] The multi-port connector is fixedly installed at the lower end of the connecting pipe and is fixedly connected to multiple arc-shaped gas struts.
[0019] Preferably, a rotary joint is fixedly installed at the upper end of the connecting pipe, and a flexible hose is fixedly connected to one end of the air pump, with one end of the flexible hose being fixedly connected to the rotary joint.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] 1. By extending the No. 1 electric push rod, the connecting frame is moved upward, causing the No. 1 slide rod to move the filter screen upward, so that the filter screen fits against the arc-shaped stirring frame. The rotation of the arc-shaped stirring frame scrapes the impurities and metal ions filtered on the surface of the filter screen towards the edge for cleaning. The collection chamber collects the scraped impurities and metal ions. After removing the blockage, the impurities and metal ions inside the collection chamber are cleaned. Thus, by moving the filter screen upward, the metal ions and impurities after the waste acid are filtered, allowing the filtered waste acid to be discharged directly, reducing the space occupied by installing additional filter devices, and preventing metal ions and impurities in the waste acid from remaining inside the pipe, making the metal ions and impurities easy to clean and collect.
[0022] 2. When the motor runs, the hollow shaft drives the stirring rod and the arc-shaped stirring frame to rotate, stirring the waste acid and accelerating the neutralization speed of the waste acid. Before the filter screen moves up, the No. 2 electric push rod first retracts and then extends, driving the collar to move up first, so that the stirring rod can flip down to a vertical position, and then move down, so that the stirring rod can be inserted into the through hole in the center of the filter screen, allowing the filter screen to move up along the stirring rod and the hollow shaft.
[0023] 3. When the air pump is pumping air, the arc-shaped air support rod unfolds, causing the stirring rod to flip and stir the waste acid. When the air pump is evacuating air, the arc-shaped air support rod retracts, causing the stirring rod to flip to a vertical position, making it easier for the filter screen to pass through.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figure 1-5In this embodiment of the present invention, a cold-drawn waste acid recycling and regeneration treatment device includes a stirring chamber 1, a filter assembly 2 movably disposed inside the stirring chamber 1, the filter assembly 2 including a filter screen 201 slidably connected inside the stirring chamber 1, a stirring assembly 3 movably disposed inside the stirring chamber 1, the stirring assembly 3 including a hollow rotating shaft 301 rotatably connected inside the stirring chamber 1, a plurality of arc-shaped air struts 302 fixedly embedded at the lower end of the hollow rotating shaft 301, a stirring rod 303 fixedly connected at one end of the plurality of arc-shaped air struts 302, an arc-shaped stirring frame 309 fixedly installed on the outer surface of the hollow rotating shaft 301, and a pump assembly 4 fixedly installed at the upper end of the stirring chamber 1.
[0032] Specifically, waste acid and alkaline solution are injected through the feed pipe at the top of the mixing chamber 1. After the filter screen 201 moves upward, the impurities and metal ions in the waste acid are lifted upward. The filtered waste acid is discharged from the outlet at the bottom of the mixing chamber 1. The stirring component 3 stirs the waste acid to accelerate the neutralization reaction. Example 1
[0033] like Figure 4 As shown, in this embodiment, multiple grooves 103 are provided at equal angles on the inner surface of the mixing chamber 1. A first sliding rod 202, which is fixedly connected to the filter screen 201, is slidably connected inside the groove 103. The first sliding rod 202 slides through the mixing chamber 1. A connecting frame 203 is fixedly connected to the upper end of the first sliding rod 202. A first electric push rod 204, which can drive the connecting frame 203 to move up and down, is symmetrically fixedly installed on the outer surface of the collection chamber 101.
[0034] In this embodiment, the first electric push rod 204 extends, pushing the connecting frame 203 upward, causing the first slide rod 202 to move the filter screen 201 upward, so that the filter screen 201 fits against the arc-shaped stirring frame 309. The rotation of the arc-shaped stirring frame 309 scrapes the impurities and metal ions filtered on the surface of the filter screen 201 towards the edge, cleaning it. Thus, by moving the filter screen 201 upward, the metal ions and impurities after the waste acid are filtered, allowing the filtered waste acid to be directly discharged, reducing the space occupied by installing a separate filter device, and preventing metal ions and impurities in the waste acid from remaining inside the pipe, making the metal ions and impurities easy to clean and collect.
[0035] like Figure 3 and Figure 4As shown, in this embodiment, a collar 304 is movably embedded in the upper end of the mixing chamber 1. A bearing is fixedly installed on the inner surface of the collar 304. A hollow rotating shaft 301 passes through the bearing and is fixedly connected to the inner ring of the bearing. A second sliding rod 305 that slides through the collar 304 is fixedly installed on the upper surface of the mixing chamber 1. A second electric push rod 306 that can drive the collar 304 to move up and down is fixedly installed on the upper surface of the mixing chamber 1 through a bracket. A motor 307 is fixedly installed on the upper surface of the collar 304 through a bracket. Two meshing gears 308 are fixedly installed at the output end of the motor 307 and at the upper end of the outer surface of the hollow rotating shaft 301.
[0036] In practice, the motor 307 operates, and through the meshing transmission of the gear 308, the hollow rotating shaft 301 drives the stirring rod 303 and the arc-shaped stirring frame 309 to rotate, stirring the waste acid and accelerating the neutralization speed of the waste acid. Before the filter screen 201 moves upward, the second electric push rod 306 first retracts and then extends, driving the collar 304 to move upward first, so that the stirring rod 303 can flip down to a vertical state, and then move downward, so that the stirring rod 303 is inserted into the through hole in the center of the filter screen 201, so that the filter screen 201 can move upward along the stirring rod 303 and the hollow rotating shaft 301.
[0037] like Figure 3 and Figure 5 As shown, in this embodiment, the air pump assembly 4 includes: an air pump 401 fixedly installed on the upper surface of the mixing chamber 1; a connecting pipe 403 fixedly installed on the inner surface of the hollow rotating shaft 301; a multi-port connector 404 fixedly installed on the lower end of the connecting pipe 403 and fixedly connected to multiple arc-shaped air struts 302; a rotary joint 405 fixedly installed on the upper end of the connecting pipe 403; a flexible hose 402 fixedly connected to one end of the air pump 401; and one end of the flexible hose 402 fixedly connected to the rotary joint 405.
[0038] In practice, when the rotary joint 405 rotates the connecting pipe 403, the air pump 401 can still pump air into the connecting pipe 403. When the air pump 401 pumps air, the arc-shaped air support rod 302 unfolds, causing the stirring rod 303 to flip and stir the waste acid. When the air pump 401 extracts air, the arc-shaped air support rod 302 retracts, causing the stirring rod 303 to flip to a vertical position, facilitating the passage of the filter screen 201. Example 2
[0039] Based on Example 1, in order to compensate for the problem that impurities and metal ions scraped off from the top of the filter 201 are not easy to collect.
[0040] like Figure 4 As shown, in this embodiment, multiple collection chambers 101 are fixedly embedded at equal angles on the outer surface of the mixing chamber 1, and a block 102 is movably embedded at the upper end of the collection chamber 101.
[0041] In practice, the collection chamber 101 collects the impurities and metal ions scraped out by the arc-shaped stirring rack 309. After the block 102 is disassembled, the impurities and metal ions inside the collection chamber 101 are cleaned to make them easier to remove.
