Description

A kind of filter

Technical field

The utility model relates to the filter of the atomic little material in a kind of convection cell, more specifically is a kind of device that atomic little material in the high viscosity fluid is filtered.

Background technology

Adhesive generally all is the liquid of high viscosity; Viscosity as the one of which is in 1000～5000CPS scope; The adhesive that is used for high accuracy or optics field then requires high especially; All need stick with glue agent like optical glass, optical lens or touch-screen etc. and come the adhesive between bonding each layer eyeglass or each layer panel must reach very high cleanliness factor, the particle diameter of the impurity that is contained should be less than 10 μ m.Ordinary circumstance is screen pack to be set with impurity screening at the discharging valve place of preparation equipment, but because adhesive has viscosity, very slow through the speed of screen pack, therefore not even plastic emitting causes very big puzzlement to production.The existing technological means that addresses the above problem that adopts is the pressurization discharging; Utilize pressure to make adhesive can pass through screen pack sooner; But because screen pack generally all is metal wire knitted structures; Under big pressure, have distortion and cause the mesh of filter screen to be out of shape, impurity that then maybe be bigger can influence product quality through filter screen.

Summary of the invention

The goal of the invention of the utility model is to disclose a kind of high efficiency filter device of guaranteeing the high viscosity fluid cleanliness factor.

The technical solution that realizes the utility model is following: comprise between upper tank body with charging aperture and the lower tank, particularly upper tank body that discharging opening is arranged and the lower tank that filter net device and heater are arranged.

The structure of described filter net device be one heating liquid is passed through the conduit grid on be provided with a screen pack.

Described heater is that the sidewall of upper tank body is jacket structured, and inlet and liquid outlet are arranged on it.

Described conduit grid has the looped pipeline of an outer rim, is in the middle of the looped pipeline that the some straight pipes that communicate with looped pipeline, looped pipeline also are provided with grid import and grid outlet.

Be provided with reinforcement between the above-mentioned adjacent straight pipe.

Connect through ring flange between described upper tank body and the lower tank.

Described ring flange has at least one seal groove, is provided with sealing strip in it.

Described upper tank body is provided with the gas upper port, and lower tank is provided with the gas lower port.

Described upper tank body is provided with form.

Described ring flange has two seal grooves, is provided with sealing strip in the seal groove.

The utility model is simple in structure, can carry out the part to the adhesive that need filter or/and whole heating can carry out plastic emitting in vacuum state operation and pressurized state, and screen pack can not be out of shape.Therefore, when can guarantee filter effect, the fluid of high viscosity there is high efficiency filter process, has solved the filtration poor efficiency of prior art and the defective of difficult quality guarantee.

The specific embodiment

See also Fig. 1～Fig. 3; The specific embodiment of the utility model is following: comprise the upper tank body 2 with charging aperture 1; High viscosity fluid such as adhesive with impurity get into upper tank body 2 by charging aperture 1, and the lower tank 4 of tool discharging opening 3 is arranged below upper tank body 2, and key is between upper tank body 2 and the lower tank 4 filter net device and heater to be arranged; Adhesive improves self temperature through heater; Can improve the rheological property of adhesive, then can pass through filter net device quickly, the adhesive after the filtration gets into lower tank 4 to carry out packing or gets into container through discharging opening 3; The structure of above-mentioned filter net device be one heating liquid is passed through conduit grid 5 on be provided with a screen pack 6; And conduit grid 5 has the looped pipeline of an outer rim; Be the some straight pipes that communicate with looped pipeline 17 in the middle of the looped pipeline; Looped pipeline also is provided with grid import 9 and grid outlet 10; Water or oil with uniform temperature gets into above-mentioned looped pipeline through grid import 9 and is flowed out by grid outlet 10 with Duo Gen straight pipe 17 again and circulate, and the conduit grid 5 that has then improved temperature can be with 6 heating of the screen pack on it, and with the adhesive heating to improve the speed that adhesive passes through screen pack 6; Aforesaid heater is meant that the sidewall of upper tank body 2 is jacket structured; Inlet 7 and liquid outlet 8 are arranged on it; Liquid (like water or oil) with design temperature forms the circulation of liquid through inlet 7, jacket structured and liquid outlet 8; Then can upper tank body 2 heating and then heating adhesive be more conducive to adhesive through screen pack 6 through heater and the filter net device with heating function; 5 pairs of screen packs 6 of above-mentioned conduit grid not only have heating function, also screen pack 6 are had supporting role simultaneously, with distortion under the pressure that reduces the adhesive of screen pack 6 in upper tank body 2; For further reducing the distortion that screen pack 6 possibly occur; Between the two adjacent straight pipes 17 of conduit grid 5, be provided with reinforcement 11, in fact large-area screen pack 6 become the screen pack of a plurality of small sizes, then can avoid the distortion of screen pack 6 basically; Can guarantee that the small impurities particle that needs are filtered out filters out; The size of mesh opening of above-mentioned screen pack 6 can be 10 μ m, and this can make adhesive reach high cleanliness factor, to satisfy the bonding requirements of optics eyeglass; Above-mentioned screen pack 6 needs often to clean or change, and therefore design makes between upper tank body 2 and the lower tank 4 and connects through ring flange 16, and promptly the end that interconnects of upper tank body 2 and lower tank 4 all has a ring flange; On ring flange 16, have a seal groove 12 at least, be provided with sealing strip in its groove, two seal grooves 12 also can be arranged; The seal groove 12 of interior ring is mainly done the sealing of screen pack 6; The sizing material that prevents filtered gets into lower tank 4, and the seal groove 12 of outer shroud is done whole colloid sealing, prevents to filter or the leakage of unfiltered sizing material; Then can guarantee to realize the connection and the sealing of upper and lower tank body, in case leak-stopping glue.In the actual use, can be provided with gas upper port 13, be provided with gas lower port 14 at lower tank 4 at upper tank body 2; In whole filter process, can through gas upper port 13 and gas lower port 14 with upper and lower tank body in vacuum pumping, the bubble that then can be when filtering possibly exist in adhesive is discharged; Vacuumize simultaneously; Upper and lower tank inner chamber can keep essentially identical pressure, can not influence screen pack 6 and filter effect, after adhesive is through filtration, gets in the lower tank 4; Can pass through the gas upper port 13 of upper tank body 2 again or/and the gas lower port 14 of lower tank 4 feeds nitrogen pressure; Can adhesive directly be pressed in the dispensing apparatus that is connected with discharging opening 3,, on upper tank body 2, also be provided with form 15 for the better storage of grasping the adhesive in the upper tank body 2; Form 15 can be common resistance to compression glass or ultraviolet ray intercepting glass, to adapt to the filtration to individual type of adhesive.
