Abstract
The utility model discloses a filtering element of polyvinyl alcohol pyroxylin. This filtering element adopts polyvinyl alcohol pyroxylin as the filtering body. Its structure is a cylindrical shape and the interior of the filtering cylinder is lined with two support tubes which are both fastened on the support frame. This filtering element has the advantages of simple structure, easy and convenient detachment and mounting and low cost and this element can be recovered or replaced at any time according to use situations. In addition, since the surface of the filtering body of polyvinyl alcohol pyroxylin can be made into different concave and convex shapes, this can increase the contact surface with the filtered liquid, thus elevating filtering efficiency. The device can partially replace the existing porous filtering devices and is applicable in the clarification and purification, solid-liquid separation, filtered recovery in such industries as beverages and brewery, pharmaceuticals, chemicals, water treatment, environmental protection and scientific research.
Description
Technical field
The utility model relates to defecate and purify, Separation of Solid and Liquid, the filtered and recycled in fields such as beverage brewing, pharmacy, chemical, water treatment, environmental protection, scientific research, specifically is a kind of polyvinyl alcohol collodion filter element that can be used in described field.
Background technology
In the process of the defecate and purify of industries such as beverage brewing, pharmacy, chemical, water treatment, environmental protection, scientific research, Separation of Solid and Liquid, filtered and recycled; extensively use the porous filter elements of making by materials such as plastics, ceramic, metal powder metallurgies, become indispensable part in the industrial production.The polyvinyl alcohol collodion is a kind of new material of developing in recent years, and the inside of polyvinyl alcohol collodion has cross-linked structure, and densification and aperture hole is uniformly arranged.At some industry, can be used as the porous filter elements of defecate and purify, Separation of Solid and Liquid, filtered and recycled according to its physicochemical property, become the part substitute of at present existing porous filter elements.
The utility model content
Technical problem to be solved in the utility model is: it is the porous filter elements of filtering bodies that a kind of polyvinyl alcohol glue cotton material that adopts is provided.This filter element is simple in structure, easy accessibility, cost are low, can recover at any time or changes according to operating position.Can partly replace present existing porous filter elements.And because the outer surface of polyvinyl alcohol collodion filtering bodies can be made into rough shape, can increase the contact-making surface with filtering solution, filter efficiency is improved.
The technical scheme that its technical problem that solves the utility model adopts is: filter element is made of the supporting base of the polyvinyl alcohol collodion filtering bodies of tubular, the interior stay pipe that has many holes, band filtrate (liquid and Inside and outside screw button.At first the internal thread of the thread of interior stay pipe one end and supporting base is buckled tighten mutually fixing, again polyvinyl alcohol collodion filter cylinder is enclosed within the stay pipe outside, pad packing ring in the place's of turning edge is fixed on polyvinyl alcohol collodion filter cylinder on the supporting base with hold-down nut then outside polyvinyl alcohol collodion filter cylinder.Polyvinyl alcohol collodion filter element in use for some time, solid matter can be covered with the outer surface of polyvinyl alcohol collodion filter cylinder, and strainability is descended, the method for available blowback makes its recovery; Because polyvinyl alcohol collodion filter cylinder easy accessibility can be changed as required at any time.The collodion filter cylinder of polyvinyl alcohol collodion filter element described in the utility model can be made into the filter cylinder of one or both ends opening according to the filter plant needs, and outer surface is the plane or is uneven filter cylinder.
The beneficial effects of the utility model are: polyvinyl alcohol collodion filter element filter cylinder easy accessibility, can change at any time; At polyvinyl alcohol collodion filter cylinder liner stay pipe, can prevent the distortion of collodion filter cylinder.The outer surface of filter cylinder is uneven shape, and filter area is increased, and filter efficiency improves.

1. polyvinyl alcohol collodion filtering bodies among Fig. 1,2. in stay pipe, 3. filter cylinder hold-down nut, 4. supporting base, 5. filtrate (liquid, 6. in the stay pipe thread, 6 '. the supporting base internal thread is buckled, 7. filter cylinder hold-down nut thread, 7 '. the supporting base outside nut is buckled, 8. the filter cylinder packing ring.
The specific embodiment
The utility model is described in further detail in conjunction with the accompanying drawings.As shown in Figure 1, polyvinyl alcohol collodion filtering bodies 1 is cylindric a, end opening and the outer structure that turns edge is arranged.Interior stay pipe 2 has many holes that filtrate is passed through; Outer surface at the mouth of pipe has thread 6.Supporting base 4 has filtrate (liquid 5, be used for fixing in the internal thread of stay pipe buckle 6 ' and fixedly the outside nut of filter cylinder buckle 7 '.During installation at first with interior stay pipe 2 and supporting base 4 by thread 6,6 ' be connected and fixed; Stay pipe outside in again polyvinyl alcohol collodion filtering bodies 1 being enclosed within, a packing ring 8 is filled up at the place of turning edge outside the collodion filter cylinder, then with filter cylinder hold-down nut 3 by sieve screw thread 7,7 ' polyvinyl alcohol collodion filter cylinder is fixed on the supporting base 4.For the filter element of the required different structure of different filter plants, polyvinyl alcohol collodion filtering bodies can be made into difformity, can be made into the both ends open outer surface and is plane filter cylinder, as shown in Figure 2; For filter area is increased, filter efficiency improves, and can be made into filter cylinder that outer surface is roughness as shown in Figure 3, Figure 4.
Claims (4)
1. polyvinyl alcohol collodion filter element, comprise polyvinyl alcohol collodion filtering bodies, interior stay pipe and be used for fixing filter cylinder and the supporting base of interior stay pipe, it is characterized in that: adopting with the polyvinyl alcohol glue cotton material is filtering bodies, its structure is cylindric, be lined with interior stay pipe in the filter cylinder, the two all is installed on the supporting base.
