Abstract
The present invention relates to a diaphragm filter plate of a filter press; one or more circles of inserting plates are arranged along the sealing surface of a diaphragm; one or more circles of inserting plate rings are arranged along the circumference of the diaphragm and the circumference of liquid holes; and the inserting plates and the inserting plate rings are respectively matched with inserting plate slots and annular inserting plate slots in the filter plate. The filter plate has the advantages that the sealing combining surface of the diaphragm and a plate core is designed into an inserting plate type sealing structure, which fundamentally solves the technological problems that in the background art, such inserting part of the diaphragm and the plate core has liquid seepage, the diaphragm is disengaged from the plate core, etc.; in addition, the filter plate fundamentally realizes the automation of the assembly technology for the diaphragm and the plate core, enhances assembly quality and fundamentally ensures product quality under the preconditions of greatly lowering the production cost of the diaphragm filter plate, greatly lowering worker's labor intensity and greatly enhancing production efficiency.
Description
Technical field:
The present invention relates to a kind of various suspension dehydration techniques such as dyestuff, inserts, stearate, kaolin, coal ore, chemical industry, environmental protection, smelting, fruit juice, pectin, medicament preparation that are used for, belong to B01D25/12, B01D25/21 and make the field.
Background technology:
All patents of the applicant, Granted publication CN2339281, title " the diaphragm plate core of chimeric connection ".Characteristics: the plate core has width on the sealing surface of its side be that M, the degree of depth are the cannelure of H, has the annular flange that can closely embed this cannelure on the barrier film, and the barrier film evagination after chimeric is in the sealing surface of plate core.Its weak point: the one, sealing property is undesirable, and reason is that barrier film annular flange is entrenched in the spill cannelure of plate face of plate core.When the barrier film eardrum, with increasing of pressure, technical barriers such as fluid leaks, barrier film demoulding difficulty appear in the fitting portion of barrier film and plate core inevitably; The 2nd, no matter be the producer that produces membrane filter plate abroad, or the producer of domestic production membrane filter plate, owing to be subjected to the restriction of its technical scheme, its barrier film is chimeric all identical with background technology with the plate core, and-------adopt manual portion of inlaying with barrier film little by little portion knocks in the spill cannelure of plate core, and can't realize the automation of its assembly technology.The result: not only labor strength is big, production efficiency is extremely low, and manufacturing cost is high, what more make enterprise's headache is that problem usually takes place assembly quality inevitably, these problems are one of the technical barriers in puzzlement present technique field always, do not achieve a solution as yet before the present patent application.
Summary of the invention:
Purpose of design: avoid the weak point in the background technology, designing a kind of one is increasing along with barrier film eardrum pressure when between barrier film and plate core, fluid leaks, stripping phenomenon between barrier film and plate core can fundamentally be resolved, and have prolonged the service life of plate core widely; The 2nd, the assembly technology of barrier film and plate core is designed to automatic assembling from hand assembled, order ground is reducing labor strength widely, is reducing production costs widely, when improving its production efficiency significantly, assembly quality fundamentally is guaranteed, solve for a long time those skilled in the art and wanted to solve, and not have the technical barrier of solution.
Design:
Characteristics of the present invention, fundamentally change the seal junction of barrier film and plate core, the sealed faying face of barrier film and plate core is designed to the board plug type hermetically-sealed construction, that is to say, be provided with a circle or ring-type plate and plate ring more than the circle at diaphragm seal line face, this plate and plate ring are sealing with seal groove in the filter plate and combine, reach the fluid leaks when fundamentally blocking the barrier film eardrum, when increasing for the barrier film eardrum pressure that fundamentally solves the background technology existence, the fluid leaks that exists between barrier film and plate core, technical barriers such as demoulding have been laid solid damping and have been cut off the basis.What deserves to be mentioned is that more in order to reach sealing effectiveness safe against all possibilities, the plate of diaphragm seal face can be that the interference sealing combines or heat fusing sealing combination or adhering and sealing combination with filter plate sealing wire casing.
Technical scheme:
1. board plug sealed type membrane filter plate, it comprises barrier film (1) and filter plate (2), be provided with the above plate of a circle or a circle, be provided with a circle or along the periphery of each fluid bore of barrier film and enclose above plate ring along barrier film (1) sealing surface, plate and plate ring are complementary with filter plate (2) centerboard groove and ring-type plugboard trough respectively.
2. the encapsulating method of board plug sealed type membrane filter plate, be provided with the above plate of a circle or a circle, be provided with a circle or the above plate ring of a circle along the periphery of each fluid bore of barrier film along barrier film (1) sealing surface, this plate and plate ring are the interference sealing with filter plate (2) centerboard groove and ring-type plugboard trough respectively and combine or be hot melt sealing combination or be the adhering and sealing combination or be the combination of interference adhering and sealing.
3. local board plug sealed type membrane filter plate, it comprises barrier film (1) and filter plate (2), laterally there is a plate (3) at the back of the fluid passing hole in the barrier film (1) and is complementary with plugboard trough in the filter plate (2).
The encapsulating method of 4. local board plug type membrane filter plate, laterally there are one or more plates (3) at the back of the fluid passing hole in the barrier film (1), is the interference sealing after the plugboard trough in this plate and the filter plate (2) is pegged graft and combine or be melting sealed combination or adopt the combination of bonding agent adhering and sealing or be the combination of interference adhering and sealing.
The present invention compares with background technology, and the one, the sealed faying face of barrier film and plate core is designed to the board plug type hermetically-sealed construction, fundamentally solved technical barriers such as fluid leaks that background technology septation and plate core fitting portion occur, barrier film disengaging plate core; The 2nd, fundamentally realized the automation of barrier film and plate core assembly technology, the high quality of assembly quality not only, and realized reducing the membrane filter plate production cost greatly, reducing labor strength greatly, under the prerequisite of enhancing productivity greatly, its product quality has had basic assurance, solve the technical barrier that those skilled in the art want to solve and never solve, obtained beyond thought economic benefit and social benefit.
