Description

Technical Field

[0001] The invention belongs to the technical field of vacuum filters and relates to a high-efficiency partitioned solid-liquid tape separation device, and is particularly relevant to the high requirements for filtering and dehydrating solid-liquid mixtures in industrial processes, such as solid-liquid separation of phosphogypsum, phosphate tailings, etc. Background Art

[0002] At present, the dehydration and filtration of phosphogypsum in my country is mostly done by traditional vacuum belt filters, which are mainly used for filtering and dehydrating solid-liquid mixtures.

[0003] Most existing solid-liquid separation devices are vacuum belt filters, which use a vacuum pump to create a pressure difference between the material and the vacuum box, squeeze out the free water in the solid by atmospheric pressure, and then collect it through a liquid collecting pipe. The dehydrated material is collected through a conveyor belt. This dehydration method is not efficient enough, and the water content of the material is not low enough.

[0004] In the existing solid-liquid separation technology, the solid-liquid mixture is mainly dehydrated under the action of atmospheric pressure. This dehydration method has limited dehydration capacity and can only reduce the water content of the solid to about 18%, which cannot meet some industrial requirements. Therefore, it is necessary to make an efficient solid-liquid separation device, which is optimized on the basis of the traditional filter and reduces the water content of the solid to 12% or below to meet industrial needs. Summary of the invention

[0005] In view of this, the purpose of the present invention is to efficiently filter and dehydrate materials such as phosphogypsum, and by setting up different areas to play different functional characteristics, the moisture content of the material can be effectively reduced to 12% or below with the coordinated cooperation of the vacuum dehydration system and the air distribution system.

[0006] To achieve the above object, the present invention provides the following technical solutions.

[0007] An efficient partitioned solid-liquid tape separation device is characterized in that the device includes a variable frequency motor, a vacuum pump, a filter cloth, a conveyor belt, a bearing, a liquid collecting pipe, a vacuum box, a gas-liquid separation tank, a fan, a heater, an air distribution manifold and other components. The tape solid-liquid separation device is similar to a conveying device. The conveyor belt is made of rubber material, and regular grooves are carved on the conveyor belt. A series of circular holes are cut between the vacuum box and the conveyor belt to filter the liquid. The material passes through the material distribution device to the conveyor belt. The variable frequency motor drives the conveyor belt to transmit and can adjust the linear speed of the conveyor belt. There is a filter cloth between the conveyor belt and the material. The vacuum pump and the vacuum box are connected by a pipeline and are well sealed. Under the action of the vacuum pump, the air pressure of the vacuum box is pumped to a set vacuum degree, forming a pressure difference with the material, and the liquid is preliminarily filtered out through the circular holes and then collected by the liquid collecting pipe. The wind source generated by the fan dries the preliminarily filtered material and blows the material away, increasing the contact area with the atmosphere, so that the moisture content of the material is reduced to about 18%, achieving the purpose of moderate dehydration. Finally, a heater is used to heat the wind source generated by the fan, and the obtained hot air is used to dry and heat the moderately dehydrated material, reducing the moisture content of the material to 12% or below; the terminal wind distributor refers to the mutually intersecting pipes connected to the fan, which can evenly distribute the wind source in the material.

[0008] As a further solution of the present invention: the filter cloth can be made of a different material to increase the friction between the filter cloth and the conveyor belt and improve its service life.

[0009] As a further solution of the present invention: a valve can be installed on the air distribution manifold to control the air output to adjust the dehydration state of the material.

[0010] As a further solution of the present invention: the liquid collecting pipe device can be made of corrosion-resistant material to increase the service life of the device, and a valve can be installed on the pipeline to control the air intake volume to improve safety.

[0011] As a further solution of the present invention: the height of the air distribution system can be set to be adjustable, so as to facilitate multi-angle dehydration and filtration of the material.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention provides a highly efficient partitioned solid-liquid adhesive tape separation device, which newly adds an air distribution system, effectively improves the material dehydration efficiency, and reduces the moisture content of the solid material to 12% or less. In addition, the axial length of the device is compressed, so that its volume and floor space are much smaller than those of traditional equipment. This device solves the dehydration problem of phosphogypsum, further reduces its moisture content, and meets most industrial requirements. BRIEF DESCRIPTION OF THE DRAWINGS
