[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 and Figure 2, an embodiment provided by the present utility model: a storage device for highly corrosive wastewater, including a storage tank 1 that can store highly corrosive wastewater. The structures arranged inside the storage tank 1 are all made of highly corrosive materials. A motor is provided at the top of the storage tank 1. The motor is an existing structure and can be realized by those skilled in the art. Since it is prior art, it will not be described in detail in this case. The bottom end of the output shaft of the motor is fixedly connected to a rotating rod 32 that supports and drives the scraper 3 to rotate. The output shaft of the motor penetrates and is rotatably connected to the top of the storage tank 1. The rotating rod 32 is rotatably connected to the middle of the inner wall of the storage tank 1. A cleaning component is arranged on the inner wall of the storage tank 1. The cleaning component includes a scraper 3 that scrapes the dirt on the inner wall of the storage tank 1 by rotation. The scraper 3 contacts the inner wall of the storage tank 1. A positioning disk 2 that provides support and drives the scraper 3 to move is arranged on the outer wall of the rotating rod 32. A support rod 31 that supports the scraper 3 is fixedly connected to the outer wall of the rotating rod 32 near the lower part of the positioning disk 2. The scraper 3 is slidably connected to the outer wall of the support rod 31. A flushing component is arranged on the outer wall of the positioning disk 2. The flushing component includes a nozzle 41 that can spray cleaning liquid. There are multiple groups of nozzles 41, and multiple groups of nozzles 41 are evenly arranged on the outer wall of the positioning disk 2. Multiple groups of nozzles 41 improve the cleaning effect.

[0032] Refer to Figure 2 , Figure 3 and Figure 4 , an adjusting component is provided at the top of the storage tank 1. The adjusting component includes a guide rod 26 that drives the positioning disk 2 to move. The guide rod 26 is rotatably connected to the top of the positioning disk 2. A positioning ring 25 that slides on the outer wall of the positioning disk 2 near the lower part of the nozzle 41 and drives the scraper 3 to move is slidably connected. A connecting plate 24 that drives the scraper 3 to move is hinged to the lower part of the outer wall of the positioning ring 25 near the nozzle 41. The right side of the connecting plate 24 is hinged to the left side of the scraper 3. A guide plate 28 is fixedly connected to the upper outer wall of the guide rod 26. Through the guide plate 28, the worm gear 23 can always drive the guide plate 28 and the guide rod 26 to rotate. When the guide rod 26 rises in cooperation, the guide plate 28 follows and rises through and is slidably connected to the middle of the worm gear 23. A cylinder 21 that provides support is fixedly connected to the top of the storage tank 1. An arc-shaped groove 210 is formed through and opened on the outer wall of the cylinder 21. By sliding the sliding rod 29 in the arc-shaped groove 210, the sliding rod 29 can rotate and move upward at the same time, driving the guide rod 26 and the positioning disk 2 to move upward, so that the scraper 3 can move inward to release the contact with the inner wall of the storage tank 1.

[0033] Refer to Figure 1 and Figure 2 , a connecting pipe 4 that can connect the cleaning liquid and transmit the cleaning liquid into the positioning disk 2 from the connecting pipe 4 is fixedly connected to the top of the positioning disk 2. The connecting pipe 4 penetrates and is slidably connected to the top of the storage tank 1.

[0034] Refer to Figure 2 ,Figure 3 and Figure 4 , the arc-shaped groove 210 is set to an arc shape. By setting the arc-shaped groove 210 to an arc shape, the sliding rod 29 can rotate and slide upward along the inner wall of the arc-shaped groove 210 while driving the scraping plate 3 to move inward, disengaging from the inner wall of the storage tank 1, preventing continuous scraping and wear of the inner wall of the storage tank 1, and improving the service life of the storage tank 1. A support plate 27 for supporting the worm 22 is fixedly connected to the top of the storage tank 1 near the right side of the cylinder 21. Two groups of support plates 27 are provided to support the worm 22. The front surface of the support plate 27 penetrates and is rotatably connected to the worm 22. An anti-slip disk is fixedly connected to the front surface of the worm 22. The anti-slip disk can be rotated to drive the worm 22 to rotate. The top of the cylinder 21 is rotatably connected to a worm gear 23. The right side of the worm gear 23 meshes with the left side of the worm 22. When the worm 22 rotates, it can drive the worm gear 23 to rotate, thereby driving the guide rod 26 to rotate and cooperate with the sliding rod 29 to be slidably connected in the arc-shaped groove 210, enabling the guide rod 26 to move upward and drive the scraping plate 3 to move inward.

[0035] Refer to Figure 2 、 Figure 3 and Figure 4 , the guide rod 26 penetrates and is arranged in the middle of the worm gear 23. The guide plate 28 penetrates and is slidably connected in the middle of the worm gear 23. A sliding rod 29 for driving the guide rod 26 to move upward is fixedly connected to the right side of the guide rod 26. The sliding rod 29 is slidably connected to the inner wall of the arc-shaped groove 210. When the sliding rod 29 rotates and is slidably connected to the inner wall of the arc-shaped groove 210, the sliding rod 29 can rotate and move upward at the same time, driving the guide rod 26 and the scraping plate 3 to move.

[0036] Working principle: When in use, first, highly corrosive wastewater is injected into the storage tank 1 for storage. When it is necessary to clean the inner wall of the storage tank 1, the motor is started. The output shaft of the motor drives the rotating rod 32 to rotate. On the one hand, the rotation of the rotating rod 32 drives the support rod 31 to rotate, and then the scraping plate 3 slidably connected to the outer wall of the support rod 31 starts to rotate. Since the scraping plate 3 contacts the inner wall of the storage tank 1, the dirt on the inner wall of the storage tank 1 can be scraped off during the rotation. At the same time, the cleaning liquid is input into the positioning disk 2 through the connecting pipe 4, and the cleaning liquid is immediately sprayed out from a plurality of nozzles 41 evenly distributed on the outer wall of the positioning disk 2 to wash the inner wall of the storage tank 1. Cooperating with the scraping of the scraping plate 3, the cleaning effect is enhanced, the efficiency and quality of the cleaning work are improved, the physical consumption and time of manual cleaning are reduced, the service life of the storage tank 1 is effectively extended, and the maintenance cost and safety hazards caused by dirt accumulation are reduced.

[0037] When it is necessary to adjust the position of the scraping plate 3, rotate the anti-slip disc to drive the worm 22 to rotate. Since the worm 22 meshes with the worm wheel 23, the rotation of the worm 22 will drive the worm wheel 23 to rotate. The rotation of the worm wheel 23 drives the guide rod 26 and the sliding rod 29 to rotate. Since the sliding rod 29 is slidably connected to the inner wall of the arc-shaped groove 210 opened on the outer wall of the cylinder 21, when the sliding rod 29 rotates, it will slide along the track of the arc-shaped groove 210. And under the shape design that the arc-shaped groove 210 is set to be arc-shaped, the sliding rod 29 will move upward while sliding. The upward movement of the sliding rod 29 drives the guide rod 26 to move upward, and the guide rod 26 drives the positioning disc 2 and the positioning ring 25 to move upward. The positioning ring 25 pulls the scraping plate 3 to slide inward on the outer wall of the support rod 31 through the connecting plate 24, so that the scraping plate 3 moves inward to release the contact with the inner wall of the storage tank 1, preventing the scraping plate 3 from continuously scraping and wearing the inner wall of the storage tank 1, playing a role in protecting the inner wall of the storage tank 1 and improving the service life of the storage tank 1. At the same time, by moving the scraping plate 3 to the middle, the scraping plate 3 can be rotated to stir, improving the treatment efficiency of the wastewater, avoiding the local accumulation of sediment at the bottom of the storage tank 1, and reducing the adhesion and accumulation of dirt.
