A partition board is used for dividing the shell body into a washing cavity and a water outlet cavity, and an exhaust valve, a material or water inlet valve, a discharge valve and corresponding material or water inlet and outlet pipelines are arranged. A hollow fibre beam filter is arranged in the washing cavity. Nanometer microcrystalline celluloses are arranged in the washing device, purified water is input for washing, impurities such as acid, sugar, coloring matter, salt, etc. in the nanometer microcrystalline celluloses can be dissolved out and discharged through small holes in the fibre wall of hollow fibre in order to trap the nanometer microcrystalline celluloses to obtain the aim of purification.
Description
The device of nano micro crystal cellulose impurity is removed in a kind of industrial washing of the utility model.
The little smart cellulose of sodium rice is the product that cellulose fibre obtains after acid hydrolysis, and it is cellulosic superfine small-particle, and grain can be suspended in and becomes colloid in the water through about 30nm.In making the little smart cellulose process of nanometer, there are impurity such as acid, sugar, pigment, salt, can't be with general filter with these Impurity removals.It can be separated with miillpore filter, but efficient is low, easily stifled film brings difficulty to industrial production.
The purpose of this utility model provides a kind of nano micro crystal cellulose wash mill, Impurity removal in the little smart cellulose of nanometer can be obtained pure product.And can realize industrial production.
Nano micro crystal cellulose wash mill provided by the utility model, wash nano micro crystal cellulose by injecting in the pure water auto levelizer, comprise a wash mill housing, the housing of this wash mill is divided into a washing cavities and a water chamber by a dividing plate with housing, on the shell of washing cavities, be provided with air bleeding valve, charging (water) valve, bleeder valve reaches to advance accordingly, the connecting pipe of discharging (water), it is characterized in that being equipped with in the said washing cavities hollow fiber bundle filter, the termination of its hollow fiber bundle sticks with glue agent and is bonded and fixed on the dividing plate, and the two-port of the every doughnut that said doughnut is intrafascicular is exposed under the dividing plate and communicates with water chamber.
The operation principle of wash mill is, the little smart cellulose colloid of the nanometer of 5-10% is injected in the washing cavities of wash mill, inject pure water washing material by pipeline to washing cavities with pump, impurity such as the acid littler than the little smart cellulose grain of sodium rice, sugar, pigment, salt permeate in hollow fiber walls, see through the doughnut outer wall and enter fibrous inside, from fiber, flow into the water chamber of wash mill, discharge from the delivery port of wash mill water chamber, the little smart cellulose of nanometer is dammed in the hollow fiber bundle outside again.Washing process is continuous, constantly adds pure water, and impurity constantly washes out, till the little smart cellulose of nanometer is purified.
Described hollow fiber bundle can be made with synthetic doughnut such as polypropylene fibre, polysulfones.The cinclides of doughnut is directly decided on the little smart cellulose particle diameter of nanometer, and generally the little 5～15nm of particle diameter than the nano micro crystal cellulose that is washed is good, is 30nm as the particle diameter of nano micro crystal cellulose, and the hollow fiber walls aperture is 20nm; Particle diameter is 50nm, and the hollow fiber walls aperture is 40nm.The controlled amount system in doughnut aperture, and suitability for industrialized production is arranged.Doughnut by hundreds of to thousands of fibrous, two of fiber stoops with epoxy bond to be fixed, and sticks into a round basin shape, cuts part fiber head and adhesive with cutter, exposes the doughnut port part, flows out from the fiber oral area in order to impurity.Circle basin shape hollow fiber bundle is fixed on the said dividing plate with epoxy bond again, and makes the doughnut port part be exposed to the bottom of dividing plate, and this dividing plate also is the gripper shoe of hollow fiber bundle.
The relevant member of each of wash mill, comprise that upper shell, inlet valve and bleeder valve and connecting pipe, dividing plate, wash mill lower cover should use making such as engineering plastics such as ABS resin, polycarbonate, polytetrafluoroethylene (PTFE), increase the compression strength of device on the one hand, on the other hand not stripping contaminant metal ions material.Each by-pass valve control should adopt polytetrafluoroethylene (PTFE) to make, and has adopted above these materials, and wash mill is acid-alkali-corrosive-resisting for a long time, and is durable in use; Engineering plastics are ageing-resistant, can bear certain pressure and do not break, and can use for a long time in 50 ℃ of left and right sides warm water.
Impurity such as the acid that exists in the utility model employing hollow fiber bundle filter wash nano micro crystal cellulose, sugar, pigment, salt, its advantage one is that the filter membrane of doughnut beam ratio equal volume has bigger filter area, general big tens times are arrived hundred times, have greatly improved filter efficiency; The one, energy acid and alkali resistance and microbiologic(al) corrosion; And doughnut injects pure water with having stopped up the usefulness again that can recoil for a long time from delivery port, discharges from charging aperture after seeing through doughnut, can remove the impurity that invests on the fibre wall, keeps original clean result.This apparatus structure is simple, and whole device dismounting, easy to assembly is convenient to each parts is cleaned, and can carry out automatic continuous washing.The utility model also can wash the particle of the organic of other suspensions and inorganic nano size except that washing nano micro crystal cellulose particle.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Accompanying drawing is the structure chart of this device embodiment.
Among the figure: 1, blast pipe, 2, air bleeding valve, 3, upper shell, 4, hollow fiber bundle, 5, connecting pipe, 6, inlet valve, 7, control valve, 8, bleeder valve, 9, fixed screw, 10, packing ring, 11, dividing plate, 12, adhesive, 13, lower cover, 14, delivery port, 15, washing cavities, 16, water chamber.
The housing of this wash mill is made up of cylindrical shape upper shell 3 and lower cover 13, and dividing plate 11 is clipped between cylindrical shape upper shell 3 and the lower cover 13, becomes a cylindrical housings with fixed screw 9 with packing ring 10 fixing seals.The top of dividing plate is washing cavities 15, and the bottom is a water chamber 16, hollow polypropylene fibre bundle 4 two and synthetic circular arc, use epoxy resin bonding, do solid back and cut part fiber head and adhesive, expose till the fiber head cavity, use adhering with epoxy resin again in the hole, garden at dividing plate 11 middle parts with cutter.
In the washing process with this device washing nano micro crystal cellulose, all need not open wash mill from being fed to discharging, it is very convenient to operate.At first open air bleeding valve 2 and control valve 7, close bleeder valve 8, inject the washing cavities 15 that the little smart cellulose gum of nanometer enters wash mill from inlet valve 6, close air bleeding valve 2 during approaching expiring, inject pure water in same inlet valve 6, hydraulic pressure is 3-5kg/cm
2Impurity such as the acid of stripping, sugar, pigment, salt are discharged from delivery port 14 through hollow fiber bundle 4 in the washing process, the little smart cellulose of nanometer down dams, after washing after a while, closed control valve 7, open bleeder valve 8 sample analysis, stop washing after qualified, close inlet valve 6, be pressed into air in blast pipe 1, pressure is 5kg/cm
