Embodiment
Fig. 1,2,3 shows a kind of structural drawing of acid-alkali-corrosive-resisting spring mechanism.In figure, this acid-alkali-corrosive-resisting spring mechanism comprises a spring body 1, spring body 1 adopts the spring steel of rectangular cross-section to roll into sped structure, the two ends of spring body 1 are plane, and the upper-end surface and lower end surface of spring body 1 set gradually a corrosion-resistant rubber cushion 3 and a spring seat board 2.Spring seat board 2 is provided with an an endoporus 2c and otch 2e, kinking structure 2d under the annular end of otch 2e side is made into arc, and described corrosion-resistant rubber cushion 3 adopts and the structure that spring seat board 2 matches (being provided with identical endoporus and otch).Spring seat board 2 outer periphery is provided with 6 the evagination bending plate 2a matched with spring body 1 end external cylindrical surface, and the inner periphery of endoporus 2c is provided with 6 the convex bending plate 2b matched with the inner cylindrical surface in spring body 1 end.Corrosion-resistant rubber cushion 3 is placed in the bottom of spring seat board 2, both otch alignment, allow kinking structure 2d under the arc of spring seat board 2 be positioned at the lower position of the spring terminal afterbody 1a of spring body 1.The surface of spring body 1 is provided with the glue-line of acid/alkali-corrosion-resistant.
Fig. 4,5 shows the semi-finished product structure figure of spring seat board.In figure, spring seat board 2 outer periphery is provided with the evagination bending plate 2a of 6 not yet bendings, and the inner periphery of endoporus 2c is provided with the convex bending plate 2b of 6 not yet bendings.For ease of the bending of evagination bending plate 2a, the both sides of evagination bending plate 2a are respectively provided with a technology groove 2f.
Adopt above-mentioned technological scheme, the having of this spring mechanism installs the features such as simple, high pressure, high compression amount, acid-proof alkaline are excellent, long service life.
High elasticity high compression amount: for the demand of pressure filter equipment, adopt that " spring design software " design meets hyperpressure and ensure the spring of high compression amount, this spring can ensure long service life according to analog data and actual fatigue test checking.
High acid resistant alkali, highly corrosion resistant: by special surface process, can reach the acid resistant alkali exceeding general spring 50 times, corrosion-resistant cycle.
Overlength life cycle: change Traditional Thinking in the design concept of conventional springs.The also tight point of both ends of the spring is carried out opening process, ensures that spring itself all covers corrosion resistant coating.Because in the carry process of spring, the also tight point in earlier stage doing opening process is wanted also tightly, and will produce counterclockwise movement, the corrosion resistant coating of as easy as rolling off a log like this destruction spring surface with spring volume below.Have employed a kind of spring seat board and corrosion-resistant rubber cushion for this reason, can ensure that the guarantee cover coat fabulous in carry process of spring is not damaged.By checking, extremely do not occur at delivery 50,000 times (being equivalent to 6 years spreadable lifes) spring surface.In marginal test process, (being equivalent to 11 years spreadable lifes) spring surface also occurs extremely can to accomplish delivery 100,000 times.According to the guarantee estimation working life of 5 years, if pressure filter adopts this spring mechanism, than using the pressure filter of original spring because safeguarding and the slow down high cost and poor efficiency that cause, approximately millions of economic losses can be reduced.
