Description

Technical Field

[0001] The utility model relates to the technical field of carbon slag collection, and more specifically to a device for collecting carbon slag. Background Art

[0002] A large amount of waste carbon slag is generated during the production of electrolytic aluminum. These carbon slags contain electrolytes, carbon powder particles and other substances that can be recycled. Their effective recycling and reuse are of great significance for resource conservation and environmental protection. Harmless treatment of carbon slag can not only avoid environmental pollution, but also recycle the resources therein, which is an important cost-reduction and efficiency-increasing measure. The flotation tank is a device for recycling carbon slag. The flotation method can effectively separate the carbon material and the electrolyte adsorbed thereon. When the flotation tank is in use, the carbon slag particles will be deposited at the bottom, and they are often salvaged and collected manually using a carbon slag spoon, which is time-consuming and labor-intensive, making the collection of carbon slag inconvenient.

[0003] The Chinese patent application number 202322438766.5 discloses a flotation device, which includes a shell, a scraping device and a stirring device. The upper part of the shell is open, and an overflow port is provided on the upper part of the front side wall of the shell. The scraping shaft is mounted on the overflow port, and the two ends are rotatably connected to the left and right side walls of the overflow port respectively. The scraping plate includes a fixed plate, an adjustment plate and a latch. The fixed plate is fixedly connected to the scraping shaft, and an adjustment groove is provided on the side of the fixed plate away from the scraping shaft. Fixed holes are provided on the left and right end surfaces of the fixed plate, and the adjustment plate can be slidably inserted into the adjustment groove. A plurality of adjustment holes are provided on the left and right end surfaces of the adjustment plate. The flotation device also has the following problems during use:

[0004] 1. During the use of the flotation equipment, a large amount of carbon slag particles will accumulate at the bottom of the flotation equipment. However, the device lacks a structure that can automatically clean the carbon slag particles accumulated inside, so it is necessary to manually enter the equipment to clean it.

[0005] 2. When using flotation method for separation, the internal materials need to be tumbled and mixed. Since the particles in the materials have a certain weight, they tend to fall to the bottom of the tank, which is not conducive to the separation of the materials. There is a lack of structure that can scrape the materials off during use.

[0006] Therefore, it is necessary to propose a device for collecting carbon slag to solve the above problems. Utility Model Content

[0037] Specifically, refer to Figure 1 and Figure 2 The bottom of the flotation tank 101 is connected to a support platform 121, which is used to support the flotation tank 101 so that the discharge pipe 120 has a certain height from the ground, thereby facilitating the cleaning of the collected carbon slag.

[0038] Specifically, refer to Figure 1 and Figure 2A top bracket 123 is connected to the top of the overflow tank 122 , and the top bracket 123 supports the stirring device 102 . An air intake pipe is installed on the stirring device 102 for adding external air into the flotation tank 101 . The stirring device 102 is installed on the top bracket 123 .

[0039] In this embodiment, the flotation tank 101 is fixed on the support platform 121, and a collection pipe 103 for collecting and discharging the internal carbon slag particles is installed at the bottom of the flotation tank 101. A stirring device 102 is installed inside the flotation tank 101, and the internal material is stirred by the stirring device 102. An air duct is installed on the stirring device 102 to inject external air into the flotation tank 101, so that the gas reacts with the material, thereby separating the solid and the electrolyte of the material by flotation. At the same time, the stirring device 102 will drive the arc plate 118 at the bottom to rotate. When the arc plate 118 rotates, the scraper 119 on one side will scrape off the solids that fall on the bottom of the tank due to gravity, so that it moves upward and reacts with the gas entering the flotation tank 101, so as to improve the efficiency of flotation.

[0040] A driving wheel is provided on the top of the stirring device 102, which is connected to an external driving device through a connecting device, thereby driving the stirring device 102 to rotate. When the stirring device 102 rotates, the solid matter deposited on the bottom of the tank will be scraped off through the arc plate 118 at the bottom, so that it moves upward, thereby improving the efficiency of flotation. At the same time, the stirring device 102 will drive the rotating rod 104 located in the collecting pipe 103 to rotate. When the rotating rod 104 rotates, it will drive the lifting block 107 to move upward through the thread, thereby moving into the top limit groove 106. At this time, the top of the lifting block 107 The blocking block 109 will be blocked in the slag discharge hole 108, so that the bottom of the flotation tank 101 is a whole, and the inclined surface of the outer side of the lifting block 107 will contact the inclined surface ring 110, and a sealing ring 111 is provided at the contacting place to increase the sealing ability when the inclined surface ring 110 and the lifting block 107 are attached together, so as to avoid the situation that the material enters the collecting pipe 103 from the slag discharge hole 108 when the equipment is used.

[0041] When the solids in the flotation tank 101 need to be cleaned, the material in the flotation tank 101 is first allowed to stand for a period of time to allow the solids in the liquid to sink to the bottom, and then the liquid in the flotation tank 101 is discharged through the pipe on the outer wall of the flotation tank 101. At this time, the carbon slag will accumulate at the bottom of the flotation tank 101. At this time, the stirring device 102 is driven in reverse to rotate by the driving device. When the stirring device 102 rotates, the carbon slag at the bottom will be cleaned inward through the arc plate 118 at the bottom, so that the carbon slag will be discharged toward the slag discharge hole 114. 08, and at the same time, the stirring device 102 also drives the rotating rod 104 at the bottom to rotate. At this time, the lifting block 107 located in the limiting groove 106 is pushed by the top reset device 115, so that it moves downward and moves into the range of the threaded portion 105. The lifting block 107 is moved downward by the rotation of the rotating rod 104. At this time, the blocking block 109 on the top of the lifting block 107 moves downward from the slag discharge hole 108, so that the slag discharge hole 108 is connected with the inside of the collecting pipe 103. Figure 3 The carbon slag will enter the collecting pipe 103 through the slag discharge hole 108, and then the discharge valve in the discharge pipe 120 is opened to discharge the carbon slag in the collecting pipe 103. When the lifting block 107 moves to the limiting groove 106 at the bottom, because there is no thread in the limiting groove 106, the lifting block 107 will not continue to move downward until the carbon slag particles in the flotation tank 101 are cleaned out.
