Description
Technical Field
The invention belongs to the technical field of solid material dehydration, and particularly relates to a clamping sheet type filter.
Background
The disk filter is widely applied to the dehydration operation of solid powder due to the characteristics of continuous operation, large unit area treatment capacity, small occupied area and the like. During filtration, the filter cake adsorbed on the filter cloth has dynamic balance formed by particle attraction, capillarity and liquid surface tension among gas, liquid and solid phases, and the balance is destroyed by the rapid reduction of the gas and liquid phases during filtration, so that the attraction among particles is increased, the gap is reduced, the volume is shrunk, and the filter cake is cracked or cracked. After the crack is generated, not only the atmosphere is communicated with the vacuum, but also the air is sucked into the vacuum to reduce the vacuum degree; and a low-resistance air channel is formed at the crack, so that the vacuum short circuit at the filter cake is realized, the filter cake cannot be sucked in a negative pressure vacuum manner, and the moisture of the filter cake cannot be reduced. This causes a problem that the disc filter which only relies on negative pressure suction has a limit moisture during filtration, that is, even if the disc filter is given a longer negative pressure suction time, the moisture cannot be further reduced. Therefore, a disc filter which can prevent the surface of the filter cake from generating cracks, so that the filter cake can be continuously sucked by negative pressure, and the moisture of the filter cake can be continuously reduced needs to be developed.
Disclosure of Invention
The invention aims to provide a sandwich type disc filter which is simple in structure and can effectively prevent the surface of a filter cake from generating cracks, so that the filter cake can be continuously sucked by negative pressure, and the water content of the filter cake can be continuously reduced.
The invention relates to a clamping piece type disc filter which is realized by the following technical scheme:
the invention relates to a clamping piece type disc filter, which comprises a main shaft, at least one filtering disc and a slurry tank, wherein the filtering disc and the slurry tank are fixed on the main shaft and are arranged along the axial direction of the main shaft, the filtering disc consists of a plurality of filtering fans, and the clamping piece type disc filter is characterized in that: also comprises clamping mechanisms arranged at two sides of each filter disc and a fixing component used for fixing the clamping mechanisms,
the clamping piece mechanism for mirror symmetry install a pair of clamping piece in every filter disc suction dry area, every clamping piece by a length with single strain a fan length unanimous, the width is 50mm-200 mm's elastic plate and constitutes the upper portion of every clamping piece open and to have bolt hole A, be equipped with the full-thread bolt in the lower part of every clamping piece, the clamping piece towards filter disc one side be the arc structure the clamping piece is far away along filtering disc rotation one side distance filter disc face in the width direction, the contrary disc that filters rotates one side distance filter disc face near.
The fixing component consists of an upper fixing piece and a lower fixing piece,
the upper fixing part is composed of a full-thread bolt and two pairs of nuts I, the full-thread bolt penetrates through the bolt holes A in the upper parts of the clamping pieces and fixedly connects the upper parts of the clamping pieces through the two pairs of nuts respectively;
the lower fixing part is composed of two support rods symmetrically welded on a main shaft shell of the filter and two pairs of nuts II, a bolt hole B is formed in the top of each support rod, and a full-thread bolt at the bottom of each clamping piece penetrates through the bolt hole B and the nuts arranged on the inner side and the outer side of each support rod to be fixedly connected with the support rods.
The invention has the advantages that:
the clamping piece on the two sides of each filtering disc can further compact the filter cake, and the filter cake is compacted and regenerated before cracks are generated due to rapid disappearance of water vapor of the filter cake, so that three-phase balance of gas, liquid and solid is reconstructed, the cracks of the filter cake are avoided, effective absorption of the filter cake in a full period of an absorption area is ensured, and water content of the filter cake of the traditional disc type filter can be reduced by 1-3% by adopting the mode compared with that of the filter cake of the traditional disc type filter;
the clamping piece type filter has the advantages that the width of the clamping piece is only 50-200mm, and the distance between the clamping piece and the filtering disc in the width direction is gradually reduced, so that the area of a pressing area of the clamping piece on a filter cake is reduced to the greatest extent, the resistance of the clamping piece on the rotation of the filtering disc is greatly reduced, and the normal rotation of the filtering disc is ensured;
according to the clamping piece type filter, the clamping pieces are made of elastic materials, and elastic avoidance can be generated when the filter cake is compressed, so that the filter cake is prevented from being scratched, the resistance of the clamping pieces to the rotation of the filter disc is further reduced, and the normal rotation of the filter disc is ensured;
the distance between each clamping piece of the clamping piece type filter and the surface of the filter disc can be adjusted through the two pairs of nuts on the upper portion and the lower portion, and therefore the working effect of the clamping pieces can be continuously optimized until the working effect is optimal.
