Technical Field

[0001] The utility model relates to the technical field of sludge treatment, and particularly relates to a device for harmless treatment of acidic sludge. Background Technique

[0002] In many industrial production processes, a large amount of acidic sludge will be generated. These acidic sludges may contain various harmful substances, such as heavy metals, organic substances, etc. If not properly treated, they will cause serious pollution to the environment and endanger human health. With the increasing improvement of environmental protection requirements and the attention to environmental pollution problems, it has become crucial to carry out harmless treatment of acidic sludge. However, the existing treatment technologies may have some limitations or deficiencies.

[0003] Sludge is generally treated by mixing it with chemical agents. The existing treatment tank only stirs the sludge through a stirring rod during the treatment process. However, the internal sludge will adhere to the inner wall of the tank body, and it may be difficult to remove due to the hardening of the sludge, which is inconvenient for the staff to clean the inside; in view of this, we need a device for harmless treatment of acidic sludge. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for harmless treatment of acidic sludge to solve the problems put forward in the above background technique.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] As Figures 1-4 shown, the utility model provides a technical solution: an acidic sludge harmless treatment device, including a machine body 1, a feed port 2 is arranged on the machine body 1, sludge and chemical agents are conveyed into the interior of the machine body 1 through the feed port 2 for treatment, a discharge port 3 is arranged on the side wall of the machine body 1, a motor 4 is fixedly installed on the outer wall of the machine body 1, a rotating rod 5 is fixedly installed on the output end of the motor 4, a stirring mechanism 6 is arranged on the outer wall of the rotating rod 5, and a scraping mechanism 7 is arranged on the stirring mechanism 6.

[0022] In this embodiment, a stirring mechanism 6 is arranged on the outer wall of the rotating rod 5. The stirring rod 62 on the outer wall is driven to rotate by the sleeve 61 in the stirring mechanism 6 to mix and react the sludge and chemical agents. At the same time, the cam 64 is squeezed by the extrusion block 65, so that the sleeve 61 can drive the stirring rod 62 on the outer wall to move up and down, and the stirring effect is better.

[0023] In this embodiment, a scraping mechanism 7 is arranged on the stirring mechanism 6. The sludge on the inner wall of the machine body 1 can be scraped by the rotation of the scraper 74 in the scraping mechanism 7. The arranged diversion groove 75 can make the scraped sludge flow down better. At the same time, the relative extrusion between the small convex block 77 and the large convex block 78 can make the stirring rod 62 drive the scraper 74 on the outer wall to vibrate, preventing the adhesion of sludge.

[0024] The above-mentioned stirring mechanism 6 includes a sleeve 61. The sleeve 61 is slidably sleeved on the outer wall of the rotating rod 5. By starting the motor 4, the sleeve 61 on the outer wall of the rotating rod 5 can be driven to rotate. One end of the bearing spring 63 is fixedly connected to the inner wall of the sleeve 61, and the other end of the bearing spring 63 is fixedly connected to the bottom end of the rotating rod 5. A stirring rod 62 is fixedly installed on the outer wall of the sleeve 61. The stirring rod 62 on the outer wall can be driven to rotate by the sleeve 61 to mix and react the sludge and chemical agents. A cam 64 is slidably sleeved on the outer wall of the rotating rod 5. The bottom wall of the cam 64 is fixedly connected to the outer wall of the sleeve 61. An extrusion block 65 is fixedly installed on the inner wall of the machine body 1. The extrusion block 65 is located above the cam 64. By driving the cam 64 on the outer wall to rotate and being squeezed by the upper extrusion block 65, the sleeve 61 can drive the stirring rod 62 on the outer wall to move up and down, and the stirring effect is better.

[0025] The above scraping mechanism 7 includes a slider 72 which is slidably connected to the inner wall of the stirring rod 62. One end of a tension spring 71 is fixedly connected to the outer wall of the slider 72, and the other end of the tension spring 71 is fixedly connected to the inner wall of the stirring rod 62. A connecting rod 73 is fixedly installed on the outer wall of the slider 72. By driving the inner slider 72 to rotate through the stirring rod 62, the slider 72 can drive the connecting rod 73 to move outward from the stirring rod 62. The connecting rod 73 penetrates through the inside of the stirring rod 62, and a scraping plate 74 is fixedly installed at the end of the connecting rod 73. By driving the scraping plate 74 at the end through the connecting rod 73 to fit against the inner wall of the machine body 1, the sludge on the inner wall of the machine body 1 can be scraped off by the rotation of the scraping plate 74. A diversion groove 75 is formed on the scraping plate 74. Through the arrangement of the diversion groove 75, the scraped sludge can flow down better. An elastic plate 76 is fixedly installed on the outer wall of the connecting rod 73, and a small convex block 77 is fixedly installed on the outer wall of the elastic plate 76. A large convex block 78 is fixedly installed on the inner wall of the stirring rod 62. The large convex blocks 78 are arranged in an array on the inner wall of the stirring rod 62, and the large convex blocks 78 are located above the small convex blocks 77. By the relative extrusion between the small convex blocks 77 and the large convex blocks 78, the stirring rod 62 can drive the scraping plate 74 on the outer wall to vibrate, preventing the adhesion of sludge.

[0026] In this embodiment, sludge and chemical agents are conveyed into the interior of the machine body 1 through the feed port 2 for treatment. Then, by starting the motor 4, the sleeve 61 on the outer wall of the rotating rod 5 is driven to rotate. Then, the stirring rod 62 on the outer wall of the sleeve 61 is driven to rotate to mix and react the sludge and chemical agents. At the same time, the cam 64 on the outer wall of the rotating rod 5 is driven to rotate and is squeezed by the upper extrusion block 65 above, so that the cam 64 drives the sleeve 61 to move downward to stretch the internal bearing spring 63. Then, through the elastic force of the bearing spring 63, the sleeve 61 moves upward to reset. Finally, when the sleeve 61 drives the stirring rod 62 on the outer wall to move up and down, the stirring effect is better. At the same time, the stirring rod 62 drives the inner slider 72 to rotate, so that the slider 72 drives the connecting rod 73 to move outward from the stirring rod 62. Then, the connecting rod 73 drives the scraping plate 74 at the end to fit against the inner wall of the machine body 1. The sludge on the inner wall of the machine body 1 is scraped off by the rotation of the scraping plate 74. Through the arrangement of the diversion groove 75, the scraped sludge can flow down better. At the same time, the small convex block 77 on the outer wall of the elastic plate 76 is driven to move through the connecting rod 73, so that the relative extrusion between the small convex block 77 and the large convex block 78 causes the small convex block 77 to drive the connecting rod 73 to vibrate. Then, the stirring rod 62 drives the scraping plate 74 on the outer wall to vibrate, preventing the adhesion of sludge.

[0027] Generally speaking, the above has described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, any modifications or improvements made without departing from the spirit and idea of the present invention are within the protection scope of the present invention.
