Abstract
The utility model relates to a mosaic welding type filter board, comprising a filter board; the contact surface of the filter board is annularly provided with one or more circles of groove; the bottom and the wall of the groove are respectively provided with one or more circles of heating element; and the contact surface of the filter board positioned at the periphery of the groove is provided with one or more circles of electric heating wire or electric heating piece. The filter board has the following advantages that: firstly, the filter board is conductively heated and fused; secondly, when the filter board is heated, the contact surface of the filter and the membrane is heated, fused and adhered simultaneously with sealing adhesion and reliable firmness, thereby being capable of efficiently preventing liquid seepage or leakage in the working process of the filter board of the membrane; thirdly, the structure is simple, and the use is convenient.
Description
Technical field
The utility model relates to a kind of embedded melting type filter plate, makes the inserted type filter plate have the heating and melting binding function, belongs to filter plate and makes the field.
Background technology
All CN1288770C of the former legal person of the application, title " a kind of membrane filter plate and preparation method ", barrier film is positioned on the filter plate, the method that adopts heating to be positioned on the filter plate frame the barrier film face directly heating make itself and filter plate frame melting sealed bonding.Advantage: not only make the seal bond height of barrier film and filter plate reliable, and realized that people want a difficult problem that solves for a long time---under assurance tightness height reliable premise, change film and do not change plate; The 2nd, the flexible barrier film line structure Design of convex-concave in the barrier film, solved barrier film when eardrum, the hard power undue concentration of diaphragm, influence the deficiency of membrane life and eardrum poor effect, the dehydration rate of filter cake is improved significantly, and prolong the service life of its barrier film greatly.Melt bonded between background technology septation and the filter plate is with after the barrier film heating, and then bonding with filter plate.Its weak point: the one, though the face of barrier film and filter plate is molten condition, the face of filter plate then is non-molten condition, bonding fastness is poor between the two, and is easily separated; The 2nd, easily cause the fusion of barrier film contact-making surface excessive, directly influence its service life.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of embedded melting type filter plate that makes the inserted type filter plate have the heating and melting binding function.
Design: to achieve these goals.Bottom land, cell wall that the contact-making surface of filter plate and barrier film is equipped with a circle or an above heating element heater of circle and filter plate contact-making surface further groove are equipped with a circle or a design of enclosing above heating element heater, are major technique features of the present utility model.The purpose of doing like this is: owing to be embedded in annular electro heater strip on filter plate groove bottom land, cell wall and the filter plate face or electric heating sheets when filter plate is heated, groove in its filter plate face, the filter plate contact-making surface all with barrier film contact-making surface and barrier film on boss touch mutually, therefore when filter plate is heated, its barrier film is heated fusion simultaneously and forms firm bonding with filter plate, make to form the high reliability sealing between filter plate and the barrier film, can prevent effectively that membrane filter plate from producing leakage or sepage phenomenon in filter process.
Technical scheme: embedded melting type filter plate, have groove on the sealing contact surface of filter plate, the contact-making surface of described filter plate and barrier film is equipped with a circle or the above heating element heater of a circle, and the bottom land of described groove, cell wall are equipped with a circle or the above heating element heater of a circle.
The utility model is compared with background technology, and the one, realized the purpose of filter plate conductive heater fusion; The 2nd, when filter plate heated, the contact-making surface of its filter plate and barrier film was heated melting adhered simultaneously, and not only adhering and sealing is solid and reliable, can prevent the sepage or the phenomenon of leakage that are taken place in the membrane filter plate course of work effectively; The 3rd, simple in structure, easy to use.
Description of drawings
Fig. 1 is the structural representation of embedded melting type filter plate.
Fig. 2 is the welding structure schematic diagram of embedded melting type filter plate and barrier film.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1.Embedded melting type filter plate has groove 2 on the sealing contact surface of filter plate 1, described filter plate 1 is equipped with a circle or the above heating element heater 3 of a circle with the contact-making surface of barrier film, and the bottom land of described groove 2, cell wall are equipped with a circle or the above heating element heater 3 of a circle.The preparation method of its embedded melting type filter plate: filter plate 1 contact-making surface hoop has a circle or the above groove of a circle, the bottom land of groove 2, cell wall are equipped with a circle or the above heating element heater 3 of a circle, are positioned to be embedded with a circle or above electrical heating wire or the electric heating sheets of a circle on groove filter plate 1 contact-making surface all around.
Embodiment 3: on the basis of embodiment 1 and 2, barrier film 4 is melt bonded with filter plate 1 electrical heating.
What need understand is: though the foregoing description is to the utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
Claims (2)
1. an embedded melting type filter plate has groove on the sealing contact surface of filter plate, it is characterized in that: the contact-making surface of described filter plate and barrier film is equipped with a circle or the above heating element heater of a circle, and the bottom land of described groove, cell wall are equipped with a circle or the above heating element heater of a circle.
