Description

Vacuum belt filter apparatus of cassette change type}

The present invention relates to a vacuum belt filter device of the cassette replacement type, and more specifically, to a cassette replacement type vacuum belt filter device that allows convenient maintenance work such as replacement or inspection of parts by separating only part of the component when replacing the filter. It is about a vacuum belt filter device.

In general, a vacuum belt filter device is capable of extracting filtered precipitates in a solid state by separating and discharging the filtrated water using a vacuum pump in the process of continuously supplying the filtrate in the form of a slurry mixed with water on a transport belt. For example, it is used in the extraction process to separate minerals such as lithium or foreign substances from waste batteries.

These vacuum belt filter devices are usually installed with a double filter cloth belt mounted on a rubber belt to enable continuous orbital movement, and a drain line connected to a vacuum pump is closely attached to the bottom of the rubber belt to suck in filtered water. The precipitates remaining on the filter belt can be separated and discharged separately.

Typically, the vacuum belt filter device is periodically replaced or repaired due to the wear of the rubber belt and the tip of the drain line in contact with it during the vacuum adsorption process, which reduces airtightness. Conventionally, the rubber belt is replaced or the drain line is replaced. In order to replace the driven belt, etc., which is installed to reduce friction at the front end of the line, the entire device must be disassembled to remove the drum where the rubber belt is installed or the drain line, which makes the work very complicated and difficult. The inconvenience caused by reassembling it is very significant.

Meanwhile, through this dehydration process of sucking out the filtered water, the object to be treated remains in the form of a cake containing some moisture, and then goes through a drying process to additionally remove the moisture contained in the cake. In the deliquoring process, the filtered water is sucked out. In order to do this, the work must be done at a high vacuum pressure, and in the drying process, the air after the solution has been removed while the deliquification process has progressed to a significant extent is sucked in, making it possible to work at a relatively low vacuum pressure compared to the deliquification process.

However, conventionally, as a single vacuum pump is used to carry out the dehydration process and drying process, it is difficult to manufacture a device with the capacity or performance of a vacuum pump that can satisfy both dehydration and drying simultaneously, as well as the difficulty in dehydration or drying. If a vacuum pump is used to focus on one part of the drying process, the vacuum pressure in the deliquoring process is low, resulting in a decrease in liquid removal speed or extraction efficiency, or excessive pressure during the drying process, which causes scattering of the object (cake). There is a risk that it will happen.

The purpose, features and advantages of the present invention described above will become clearer through the following detailed description. Hereinafter, a preferred embodiment of the present invention will be described based on the attached drawings.

1 to 8 show a preferred embodiment of the present invention. As shown in Figure 1, the vacuum belt filter device 100 of the present invention extracts solid filtered precipitates such as minerals by sucking out water by vacuum adsorption in the process of continuously supplying the filtered material on the conveyor. In this way, a conveyor belt (20) made of rubber or the like is mounted on the belt drum (14) arranged on the left and right, and a filter cloth belt (21) on which the filtered material is placed is installed on the upper surface of this conveyor belt (20). .

This filter cloth belt 21 is equipped to spray water on the filtered matter by a spray nozzle 16 provided at the top to transport it in the form of a slurry mixed with solid and liquid, and the bottom of the conveyor belt 20 is equipped with filtered water.

A vacuum tank (40) for storing and draining the filtered water is connected to this vacuum manifold (30), and this vacuum tank (40) ) is connected to a vacuum pump 41 and is equipped to extract water by vacuum operation.

Here, the vacuum tank 40 or the vacuum pump 41 includes a first vacuum tank 40a, a second vacuum tank 40b, and a first vacuum pump 41a that can be operated selectively or simultaneously depending on the processing process, etc. It can be composed of a second vacuum pump (41b), which can be used selectively depending on the treatment process by varying the capacity or performance of the tank or pump, or can be used simultaneously depending on the treatment process even if they are provided with the same capacity or performance. It can be operated or used selectively or alternately.

For example, in the deliquification process to remove filtered water due to the high moisture content of the object to be treated, either the vacuum tank 40 or the vacuum pump 41 with a larger capacity is selectively used, and the object to be treated is caked after the deliquorization process. In the drying process to remove moisture, one of the vacuum tank 40 or the vacuum pump 41 with a smaller capacity can be used, which means that the vacuum pump 41 is operated with a large vibration pressure in the liquid removal process to remove liquid. In addition to increasing the speed and extraction effect, the drying process is operated with a relatively small vibration pressure to enable stable drying operation.

Meanwhile, a duct 17 for discharging filtered precipitates or a backwash nozzle 50 for regenerating the filter cloth belt 21 itself is installed on one side of the filter cloth belt 21, and a drain filter ( Water can be filtered by another filtration device 50, including 51), and the water can be filled in the water storage tank 53 so that it can be reused for other purposes.

It is positioned in a maintained state and is installed to be interlocked with the rotational drive of the conveyor belt 20. On the surface of the conveyor belt 20, there is a drain groove 22 extending laterally and a center of the drain groove 22. A discharge hole 23 is formed in the portion so that the filtered water sucked out from the filter cloth belt 21 during the filtration process can be discharged.
