Abstract
The utility model provides a non-return anti-leakage device which comprises a horn-shaped opening formed on the inner side of a vacuum extraction pipe, the bottom of the horn-shaped opening is spliced with the inner wall of the vacuum extraction pipe to form an ash storage groove for storing back flow falling foreign matters, and an ash removing port and a ball valve are arranged on the outer wall of the vacuum extraction pipe in the position corresponding to the ash storage groove. In the utility model, the vacuum pipe in the conventional vacuum granulation reaction kettle is improved, so that the fine solid particles generated due to stirring and soaring in the reaction kettle and the water vapor and liquid phase formaldehyde sucked by negative pressure the vacuum extraction pipe in the granulation reaction kettle can not flow back and influence the discharging quality, thereby facilitating the clearance of the solid dust and waste liquor, and improving the appearances, the impact strengths and other performances of amino-film plastic products.
Description
Technical field
The utility model relates to the fine chemistry industry production equipment, relates in particular to the neglected loading of a kind of non-return reverse osmosis and puts.
Background technology
The existing so far 80 years history of amino film plastics development, amino film plastics (UFC) is one of synthetic thermosets of chemical industry, synthetic by melamine (melamine), formaldehyde, urea for the primary raw material polycondensation, add an amount of wood pulp, cellulose again and be main stuffing and colouring agent, emulsifying agent, inside and outside lubricant agent prepares.The product of amino film plastics has ceramic outward appearance true to nature, smooth surface, lovely luster, nontoxic, tasteless.Simultaneously, compare with ceramic material, amino film plastics has and is difficult for broken, corrosion-resistant, anti-aging, rub resistance, the high characteristics of case hardness, is widely used in fields such as Aero-Space, electrical instrumentation, communication, automobile decoration, tableware, daily-use electrical appliance accessory, industrial electrical equipment accessory, computer fittings in recent years.Then be widely used in high-grade field of sanitary ware in areas such as the U.S., Europe, and promote with annual about 50% growth rate.
The production process route of amino film plastics has two at present, what most countries mainly adopted is wet route, wet route is: urea and formaldehyde at first generate resin in reactor, then filler and other auxiliary materials in kneader and mixed with resin, again at the drier inner drying, then pulverizing, ball milling, be screened into end product.The vacuum reaction still is the capital equipment of amino film plastics processing, mainly is made up of kettle, rotating mechanism, water circle device, vavuum pump, vacuum exhaust pipe, still seat etc.Vacuum exhaust pipe connects the vacuum kettle, vavuum pump effect under make and form vacuum state in the kettle, carry out closed production.But, because the negative pressure traction of ascension effect that causes during the rotation of the paddle in the kettle and vavuum pump, make tiny solid particle and the steam in the kettle, formaldehyde drop in the material rise near the vacuum tube exhaust tube, part is adsorbed on the vacuum suction inside pipe wall, after vacuum environment is destroyed, the fine particle sedimentation, and waste liquid is back to finished product frosting in the kettle along vacuum exhaust pipe, influence end product quality, pollute discharging opening.
The utility model content
At above problem, the utility model provides the neglected loading of a kind of non-return reverse osmosis to put, and can collect solid granulates and waste liquid that sedimentation refluxes, prevents that it from falling into kettle and polluting finished product, and the influence reaction is carried out.And simple in structure, easy cleaning.
The utility model provides the neglected loading of a kind of non-return reverse osmosis to put, comprise tubaeform mouth, cleaning door, ball valve, storage ash-pit, seal cover, vacuum exhaust pipe, described tubaeform mouth is positioned at vacuum exhaust pipe inside, lower aperture is communicated with reactor and engages fixing with the vacuum suction inside pipe wall, top opening leads to vacuum exhaust pipe, and top opening internal diameter is inverted tubaeform less than the lower aperture internal diameter.Described storage ash-pit when solid granule pastes the vacuum exhaust pipe sedimentation, can be fallen into the storage ash-pit, thereby avoided impurity to fall the influence that is caused after rise by vacuum suction inside pipe wall and tubaeform mouthful of closed formation of outer wall, has reduced pollution.Described cleaning door weldering is connected on the vacuum exhaust pipe lateral wall, be communicated with the storage ash-pit, be welded with several piece on the ash removing opening outer wall and offer the angle bar of groove, being fixed with an end in the groove is spherical bolt, bulbous end can be rotated around notch, and the bolt other end has circular nut, and the rotating shaft device of seal cover by being welded on the cleaning door outside can switch closure, the seal cover inboard be provided with can with the cannelure of the tight interlock of cleaning door, it is tightr to make that closing section engages.The seal cover outside is welded with and the same number of fixture of cleaning door outer wall angle bar, when seal cover is closed, and in the hole slot with rotating bolt card people seal cover fixture, the rotary annular nut, lock sealing covers, and further guarantees the sealing state of vacuum tube.Offer conduction pipe on the opposite side storage ash-pit, conduction pipe is controlled open closed by ball valve, convenient waste liquid of deriving along the vacuum tube condensing reflux.
