Description

Technical Field

[0001] This utility model relates to a calcium fluoride sludge separation device, and more particularly to a centrifugal separation device based on calcium fluoride sludge. Background Technology

[0002] In the recycling and treatment of calcium fluoride sludge, a separation device is needed to separate the acid-washed calcium fluoride particles from the soluble impurities dissolved in the acid washing solution, thereby purifying the calcium fluoride. Based on this, existing separation devices for calcium fluoride sludge are generally separation-type devices, with a structure similar to that shown in patent 202420031026.1. These include a fixed outer tank and an inner tank with a separation mesh. During use, an external device drives the inner tank to rotate, causing the calcium fluoride sludge placed inside to rotate and separate. The acid washing solution in the calcium fluoride sludge is discharged outwards through the separation mesh and collected for recycling. The calcium fluoride particles are trapped inside the inner tank and recovered by operators after separation, achieving solid-liquid separation of the calcium fluoride sludge.

[0003] The drawback of this centrifugal separator is that existing separators, in order to recover calcium fluoride particles, generally require operators to insert the collection device into the inner drum to collect the calcium fluoride particles at the bottom; or an external tilting device to tilt the entire outer and inner drums, causing the calcium fluoride particles accumulated at the bottom of the inner drum to be dumped outwards. However, the first discharge method increases the workload of operators and has the problem of incomplete collection; the second discharge method has certain safety hazards, as the separator may tip over completely, or some parts inside the separator may loosen or shift after tilting.

[0004] Therefore, a centrifugal separation device that facilitates material discharge is needed. Utility Model Content

[0007] In the aforementioned centrifugal separation device based on calcium fluoride sludge, multiple fastening components are connected around the transmission component, and multiple limiting holes that cooperate with the fastening components are distributed around the top of the separation cylinder. The end of the fastening component extends to the outside of the transmission component and fastens to the limiting hole.

One end of the fastening plate is provided with an elastic element, both ends of the elastic element are fastened to the transmission component, the middle part of the elastic element is in contact with the fastening plate, and the other end of the fastening plate is fastened to a limiting hole.

[0009] In the aforementioned centrifugal separation device based on calcium fluoride sludge, each buckle plate has two parallel slots on the outer side of the transmission component, and the buckle plate is fastened to the transmission component via the slots.

[0010] In the aforementioned centrifugal separation device based on calcium fluoride sludge, C-shaped limiting parts are formed on both sides of the bottom of the transmission component, and the transmission component is fastened to the mounting plate through the limiting parts.

[0011] In the aforementioned centrifugal separation device based on calcium fluoride sludge, a gap cavity is formed between the annular nozzle and the separation cylinder. The two ends of the handle are connected to the mounting plate via bending portions. The middle part of the handle is located inside the gap cavity. The lower end of the limiting portion extends into the gap cavity and is connected to the mounting plate via bending portions.

[0015] Compared with the prior art, this utility model has the following characteristics: (1) This utility model uses the structural cooperation of the separation cylinder, inner barrel and transmission component to enable the inner barrel to be placed directly in the placement cavity of the separation cylinder during installation. The transmission component is then used to limit the two, so that the inner barrel can rotate synchronously with the separation cylinder when the separation device is working, thus realizing the separation function. After the separation is completed, the operator can remove the transmission component and take out the inner barrel directly and pour it out, thereby effectively reducing the difficulty of collecting calcium fluoride particles for the operator and avoiding the residue of calcium fluoride particles. (2) By limiting the connection structure of the transmission component, on the one hand, the transmission component can be fixed in the separator after installation and realize the transmission function of the inner barrel. On the other hand, the height of the inner barrel can be limited, thereby reducing the vibration of the inner barrel during rotation. On this basis, through the structural cooperation of the transmission pin and the transmission hole, the separator can also drive and limit the bottom of the inner barrel, thereby improving the synchronous rotation effect of the separator and the inner barrel. Therefore, this invention facilitates the collection of calcium fluoride particles by operators and ensures the effective collection of calcium fluoride particles. Attached Figure Description

[0022] Each buckle plate 10 has two parallel slots 12 on the outer side of the transmission component 8. The buckle plate 10 is fastened to the transmission component 8 via the slots 12. The upper middle part of the buckle plate 10 is provided with a handle for the operator to control the sliding.

[0023] The bottom sides of the transmission component 8 form C-shaped limiting parts 13, which are located outside the slot 12. The transmission component 8 is fastened to the mounting plate 6 via the limiting parts 13.
