Description

Technical Field

[0001] This utility model relates to the field of mineral flotation technology, and in particular to a desliming device for a mineral processing mixing tank. Background Technology

[0002] Sometimes, fine mud and mud clumps formed by fine mud are mixed and attached to the surface of coarse ore particles in the slurry. These fine muds are a disturbance factor in the flotation process, which will directly affect the separation index and the consumption of mineral processing reagents. Therefore, desliming is a key preparatory operation before flotation. The foam generated during the desliming process is very rich and often overflows the flotation cell, affecting the normal progress of the mineral processing and extending the flotation time accordingly, which to some extent increases the input cost of the flotation process.

[0003] To address the aforementioned technical problems, existing patent (CN217313906U) discloses a desliming device for a mineral processing mixing tank, comprising a scraper mechanism, a spiral stirring assembly, and a bottom plate. The scraper mechanism is located at the upper edge of the mixing tank, the spiral stirring assembly is located inside the mixing tank, and the bottom plate is located at the lower part of the mixing tank. This method enables the timely scraping of foam generated within the mixing tank, significantly improving scraping efficiency, effectively reducing flotation pressure, and effectively solving the problem of foam failing to overflow from the mixing tank. This allows the desliming process to proceed more completely within the mixing tank. Furthermore, driven by the spiral blades, the slurry within the mixing tank forms a bottom-up reciprocating circulation, facilitating rapid foam rise and further improving desliming efficiency.

[0004] However, in the aforementioned existing technology, the bottom plate drives the slurry and foam to move upward, causing the remaining foam to overflow through the edge of the mixing tank, which can easily lead to some of the slurry also overflowing. Utility Model Content

[0005] The purpose of this utility model is to provide a desliming device for a mineral processing mixing tank, which aims to solve the technical problem in the prior art where the bottom plate drives the slurry and foam to move upward, causing the remaining foam to overflow through the edge of the mixing tank, which easily leads to some slurry overflowing as well.

[0006] To achieve the above objectives, this utility model employs a desliming device for a mineral processing mixing tank, comprising a tank body and a desliming mechanism. The desliming mechanism includes a support plate, two vertical plates, a rotating roller, a driven wheel, two limiting rings, multiple stirring rods, multiple scraper rods, a filter plate, a feed pipe, a discharge pipe, a rotating assembly, a lifting assembly, and a collecting assembly. The collecting assembly is located on the outside of the tank body. One end of each of the two vertical plates is fixedly connected to the collecting assembly, and the other end of each of the two vertical plates is fixedly connected to the support plate. The filter plate is located inside the tank body. The lifting assembly and... The filter plate is fixedly connected. One end of the rotating roller passes through the support plate and is fixedly connected to the driven wheel. The other end of the rotating roller passes through the filter plate and is inserted into the inside of the barrel. Two limiting rings are respectively sleeved on the outside of the rotating roller and respectively attached to the support plate. Multiple stirring rods are fixedly connected to the rotating roller and located inside the barrel. Multiple scraper rods are fixedly connected to the rotating roller and attached to the upper surface of the barrel. The feed pipe and the discharge pipe are both fixedly connected to the barrel. The rotating assembly is used to drive the driven wheel to rotate.

[0007] The rotating assembly includes a motor, a drive wheel, and a belt. The motor is fixedly connected to the support plate and located on the bottom surface of the support plate. The output end of the motor passes through the support plate and is fixedly connected to the drive wheel. The belt is sleeved on the outside of the drive wheel and the driven wheel.

[0008] The collection assembly includes a collection hopper and a waste discharge pipe. The collection hopper is fitted onto the outside of the barrel and is fixedly connected to the barrel. The waste discharge pipe passes through the collection hopper and is fixedly connected to the collection hopper.

[0009] The lifting assembly includes a hydraulic cylinder, a lifting plate, and a sliding plate. The sliding plate is slidably connected to the barrel body. One end of the sliding plate is fixedly connected to the filter plate, and the other end of the sliding plate is fixedly connected to the lifting plate. The hydraulic cylinder is disposed on the upper surface of the support plate, and the output end of the hydraulic cylinder passes through the support plate and is fixedly connected to the lifting plate.

[0010] The barrel body has a groove that is adapted to the sliding plate.

[0011] The desliming device for the mineral processing mixing tank further includes a mounting frame and a transparent plate. The mounting frame passes through the tank body and is fixedly connected to the tank body. The transparent plate is fixedly connected to the mounting frame and is located inside the mounting frame.

[0012] This utility model discloses a desliming device for a mineral processing mixing tank. The lifting assembly is fixedly connected to the filter plate. One end of the rotating roller passes through the support plate and is fixedly connected to the driven wheel. The other end of the rotating roller passes through the filter plate and is inserted into the interior of the tank. Multiple stirring rods and multiple scraper rods are fixedly connected to the rotating roller. In actual use, the slurry and foaming agent are added to the tank through the feed pipe. Then, the lifting assembly moves the filter plate downwards until it contacts the upper surface of the slurry. The rotating assembly then drives the driven wheel to rotate, which in turn drives the rotating roller to rotate. The rotating roller then drives the multiple stirring rods and scraper rods to rotate. The stirring rod rotates, thus mixing the slurry and foaming agent to generate a large amount of foam mixed with fine mud. The foam passes through the filter plate, and at the same time, the rotating roller drives multiple scrapers to rotate, thereby removing the foam that rises from the top of the tank into the collection assembly. After the slurry and foaming agent have reacted, only the residual foam in the tank remains. The lifting assembly moves the filter plate upward, and the filter plate drags the residual foam upward. Then, the scrapers remove the residual foam above the filter plate. This method effectively solves the problem in the prior art where the bottom plate moves the slurry and foam upward, causing the remaining foam to overflow through the edge of the mixing tank, which easily leads to some slurry overflowing as well.
