Abstract
The invention discloses a ceramic membrane tube sealing structure. The structure is characterized in that a perforated plate is arranged at the mouth of a filter barrel; a ceramic membrane tube is inserted into an installation hole of the perforated plate; an elastic seal ring with wedge-shaped cross section is sleeved on the outer diameter of the ceramic membrane tube; and an upper platen is arranged on the upper layer of the perforated plate in parallel, is locked on the perforated plate by uniformly distributed compression bolts and compresses the seal ring. The structure has the following beneficial effects: the structure is simple, is effective in sealing, greatly reduces the quantity of the parts and lowers the cost; the ceramic membrane tube is very simple to assemble and disassemble; during disassembly, the bolts only need to be unscrewed and the upper platen is taken down, thus the ceramic membrane tube can be conveniently changed; and the outer diameter of the sealing structure is just 5 millimeters larger than that of the ceramic membrane tube, so the encircle of the whole filter equipment is greatly reduced and the structure is more compact.
Description
Technical field
The present invention relates to the art of filters of Separation of Solid and Liquid, especially the ceramic membrane tube sealing structure of purpose ceramic-film filter.
Background technology
The advantages such as the pottery inoranic membrane has that chemical stability is good, acid and alkali-resistance and organic solvent, high temperature resistant, long service life can be widely used in the technical process such as filtration, purification, degerming, removal of impurities of the industries such as petrochemical industry, metallurgy, food, pharmacy, environmental protection.Many ceramic-film tubes are arranged in parallel within the filter, the pore inwall of ceramic-film tube is coated with ceramic membrane and forms filtration channel, during work with pump need filter liquide pump into and the filtration channel of flowing through in, rete is retained down the material of all particle diameters greater than membrane aperture, scavenging solution leaches by rete and supporter, be filtered the direction of liquid flow and the perpendicular direction that scavenging solution oozes out, form cross-flow filtration.
Ceramic-film tube is fixed on the sealing problem that needs to solve ceramic-film tube and metallic element in the filter, if seal badly, filtrate can produce seepage, directly affects the separating and filtering effect of filter, causes scavenging solution purity not meet the requirements.The end seal structure of ceramic-film tube as shown in Figure 1 at present, in the installing hole of porous plate 7, embed first bearing 3, bearing 3 utilizes the round nut 8 of bottom, the step surface on top to compress equalizing bed 6, be fixed on the porous plate 7 and the realization sealing, ceramic-film tube 9 passes bearing 3 endoporus, its oral area utilization is pieced together cap 1 and is pressed on the bearing 3 with gland 2, between ceramic-film tube 9 and bearing 3 endoporus, utilizes O type circle 4 and packing ring 5 to seal.This hermetically-sealed construction more complicated, loading and unloading are trouble very, and needs specific purpose tool, and consumable accessory is many; Need to take into account simultaneously the many places sealing problem during sealing, and rely on multiple parts and cooperatively interact and could realize sealing, so reliability is relatively poor.A whole set of hermetically-sealed construction takes up room larger, the maximum cylindrical of hermetically-sealed construction is larger nearly one times than the cylindrical of ceramic-film tube own, cause the equipment external diameter large, weight increases, the seal that adds whole hermetically-sealed construction need be made many molds, manufacturing expense is larger, cause the manufacturing cost of integral device significantly to increase, and the equipment heaviness is inharmonious.
Summary of the invention
The applicant is for the seal structure complex of above-mentioned existing ceramic-film tube and metallic element, poor reliability, large, the high in cost of production shortcoming in space, a kind of ceramic membrane tube sealing structure rational in infrastructure is provided, thereby can simplifies hermetically-sealed construction, the reliability of Effective Raise sealing.
The technical solution adopted in the present invention is as follows:
A kind of ceramic membrane tube sealing structure, the oral area of filter cylinder is provided with porous plate, ceramic-film tube interts in the installing hole of porous plate, be arranged with the elastic seal ring that the cross section is wedge type on the external diameter of ceramic-film tube, top board is set in parallel in the upper strata of porous plate, be locked on the porous plate by uniform hold-down bolt, and the press seal circle.
It is further characterized in that: the external diameter interference fit of described internal diameter of the seal ring and ceramic-film tube, and the minimum diameter of described sealing ring external diameter is less than the installing hole diameter of porous plate, and maximum gauge is greater than the installing hole diameter.
The circular hole of described top board distributes identical with porous plate, and the circular hole aperture value is between the aperture value of the installing hole of the external diameter value of ceramic-film tube and porous plate.
Beneficial effect of the present invention is as follows:
The present invention utilizes the sealing ring in wedge type cross section, makes sealing ring generation strain by the forward thrust, thereby fills up the installing hole gap of ceramic-film tube and porous plate, reach the effect of effective sealing, simple in structure, greatly reduced the quantity of part, reduced cost.The present invention's loading and unloading are very simple, need only looser a bolt during dismounting, take down top board and get final product, and can change easily ceramic-film tube.And this hermetically-sealed construction is only than the large 5mm of ceramic-film tube external diameter, and a whole set of filter apparatus cylindrical reduces greatly, and structure is more compact.
Description of drawings
Fig. 1 is the end seal structure of existing ceramic-film tube.
Fig. 2 is the partial sectional view of hermetically-sealed construction of the present invention.
Fig. 3 is the top view of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, porous plate 7 of the present invention is placed on the oral area of cylindrical shell 13, the installing hole slightly larger in diameter of porous plate 7 is in the external diameter of ceramic-film tube 9, sheathed elastic seal ring 10 on the external diameter of ceramic-film tube 9, sealing ring 10 as shown in Figure 3, the cross section is wedge type, the external diameter interference fit of its internal diameter and ceramic-film tube 9, the minimum diameter of its external diameter is less than the installing hole diameter, and maximum gauge is greater than the installing hole diameter, ceramic-film tube 9 passes the installing hole of porous plate 7, rely on sealing ring 10 to be stuck on the porous plate 7, recycle 12 pairs of sealing rings of a slice top board 10 and compress this moment, and the circular hole of top board 12 distributes identical with porous plate 7, and Circularhole diameter is between the installing hole diameter value of the external diameter value of ceramic-film tube 9 and porous plate 7.Utilize 6～10 uniform hold-down bolts 11 with top board 12 and porous plate 7 lockings, this moment is under the thrust effect of top board 12, sealing ring 10 and then the generation strain that is squeezed, thus fill up gap between the installing hole of ceramic-film tube 9 and porous plate 7, reach the effect of effective sealing.
More than describing is explanation of the invention, is not that limited range of the present invention is referring to claim to the restriction of invention, and in the situation of spirit of the present invention, the present invention can do any type of modification.
