Description

Technical Field

[0001] The invention belongs to the technical field of vacuum filters, and relates to a novel high-efficiency double-vacuum cassette solid-liquid separation equipment, and is particularly relevant to the high requirements for filtering and dehydrating solid-liquid mixtures in the industrial process. Background Art

[0002] At present, the dehydration and filtration of industrial products with low viscosity in my country are mostly done by traditional vacuum belt filters, which are mainly used for filtering and dehydrating solid-liquid mixtures. The existing vacuum belt filter is a set of vacuum boxes in the middle. The vacuum pump creates a pressure difference between the material and the vacuum tank. The free water in the slurry is filtered out by the vacuum negative pressure, collected through the liquid collecting pipe, and then the liquid is discharged through the gas-liquid separation tank. The dehydrated material is output through a conveyor belt. However, the wide filter belt has the phenomenon that the moisture content in the middle suction groove area is low and the moisture content at the edge of the rubber belt is high. This phenomenon leads to unstable filtration effect and cannot meet production needs in some industrial production.

[0003] Therefore, it is necessary to make an efficient solid-liquid separation equipment, optimize the design based on the traditional filter, further reduce the moisture content of the solid, and stabilize the material filtration effect to meet industrial needs. Summary of the invention

[0004] In view of this, the purpose of the present invention is to filter and dehydrate non-sticky materials efficiently, and to establish a double vacuum system to exert greater functional characteristics respectively, make the vacuum zone distribution more reasonable, and effectively reduce the moisture content of the material.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: The technical solution of the present invention provides a new type of high-efficiency double vacuum box solid-liquid separation equipment, characterized in that the equipment includes a frame body, a filter cloth, a rubber belt, a vacuum box, a liquid collecting pipe, a gas-liquid separation device and other components; the solid-liquid separation device carves regular grooves on the rubber belt, i.e., a guide groove, and punches a series of circular holes between the vacuum box and the rubber belt to filter the liquid. The gas-liquid separation device is connected to the vacuum box by a pipeline and a liquid collecting pipe, and is well sealed.

[0006] The technical solution of the present invention provides a new type of high-efficiency double vacuum box solid-liquid separation equipment, which is characterized in that in the working state, the material is placed on the filter cloth on the rubber belt, a pressure difference is formed between the material and the vacuum box, the liquid is filtered out through the circular hole, and then collected by the liquid collecting pipe. The filter cloth is driven with the rubber belt and the linear speed of the rubber belt can be adjusted.

[0007] As a further solution of the present invention: the filter cloth can be replaced with a new material to increase the friction between the filter cloth and the conveyor belt; a valve can be installed on the gas-liquid separation tank to control the amount of air extraction; and the liquid collecting pipe device can be made of corrosion-resistant material to increase the service life of the equipment.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention provides a new type of high-efficiency double vacuum box solid-liquid separation equipment, wherein the high-efficiency solid-liquid separation equipment is to set two groups of vacuum boxes with the filtration area evenly divided longitudinally below the belt filter, so that a pressure difference is formed between the material and the vacuum box in the working state, which solves the problem that the suction filtration in the middle is good and the suction filtration at both ends is poor when the traditional belt filter has a wide rubber belt, so that the material reaches a state of deep dehydration. Through the above method, the present invention can improve the dehydration efficiency of the material and reduce the moisture content on the basis of the traditional filter. The dehydration problem of the solid-liquid mixture can be solved efficiently and quickly, and the moisture content of the mixture can be reduced to an ideal index.

[0009] Different from traditional filtration equipment, the double vacuum box system compresses the axial length of this equipment, making its volume and floor space much smaller than traditional equipment. This equipment solves the problem of uneven filtration, further reduces its moisture content, and meets most industrial requirements. BRIEF DESCRIPTION OF THE DRAWINGS
