Abstract
The invention relates to a method of preparing an air filter element using diatomaceous earth as base material. According to the characteristics of the diatomaceous earth, the formula of the filter element material is determined, and in the process of preparing the filter element, parameters are transmitted by a sensor, then a program control machine controls the size spraying speed and the size spraying sector angle of an air pressure ejector on non-woven fabric, so that the thickness of the size on the working surface of the non-woven fabric can be completely consistent, and the problem that the product quality is not reliable due to the non-uniformity of the size brushed by the conventional process is avoided; the core body structure of a core board which is electrically heated and dried under the real-time control of the program control machine is ordered and the adsorption property is consistent, and the reciprocating action of the roller press, the frequency and the rolling pressure can also depend on the real-time control of the program control machine, so that the high-quality filter element body can be produced.
Description
Technical field
The present invention relates to the preparation method of a kind of air filter core body for dust-proof field, the preparation method of a kind of air filtration core with kieselguhr as base material.
Background technology
Airfiltering concept and behave, of common occurrence.Especially need the today administered energetically in air pollution, except comprehensive control environmental impact assessment difference and cause air pollution enterprise in addition to, simulate pure and fresh environment, the artificial equipment layer bringing up negative oxygen ion gas field go out unconsciously ground to market.Such as on market, the Yadu air filter of sale, Gree air filter etc. have preferable sales achievement.
Study current commercial air filter unit and the development trend of filter technology, its technological means mostly uses and arranges filter screen (film) at the air intake of filter and filter thick dirt, inlet gas carried out electronics except micronic dust with filtering core dedusting or with high-voltage arc dedusting method again, finally utilize in exit water atomization mode that outlet air adds humidification and process.
Utilizing current material to carry out in the example of dust removal by filtration, Chinese patent CN103997085A gives the dust-proof problem of the structure solution dust-proof radiating type wireless charger of employing " dust-proof stratum reticulare, activated carbon adsorption layer and diatomite adsorption layer ".
Chinese patent CN203954839U discloses the frame mode using " being provided with filter screen, Maifanitum, activated carbon and natural diatom mud ceramic layer on running water outlet mouth " for tap water clarifier.
The characteristic utilizing kieselguhr to come from silicate remains solves automatically to add the dust-proof problem of soil, Chinese patent CN203043930U disclose automatically add in soil dust guard for fixing packed diatomaceous fixture structure.
To sum up, utilize kieselguhr to solve site operation, dust-proof, the dust removal problem of living environment are also the one in multiple technologies means option.But, for using kieselguhr, how to improve airfiltering quality, the most creatively realizing approximately can the airfiltering purpose of melancholy, must be so that the kieselguhr filtering core as main material is carried out brand-new design, and during preparing filtering core also will to its production process omnidistance monitor, adjust its processing step preparing product, the product that final output high-quality low-material-consumption environmental impact assessment is up to standard at any time reading on the premise of production process each stage parametric variable.
Summary of the invention
The technical problem to be solved is to provide the preparation method of a kind of air filtration core with kieselguhr as base material.The filter element produced in this approach can be to be that core material manufactures the manufacturer of air filter and provides and set up the basis of company standard with kieselguhr, thus avoids the inconsistent difficult problem of air filtration matter core body workmanship.
To this end, the technical scheme that the present invention solves described problem is: the preparation method of a kind of air filtration core with kieselguhr as base material, including step:
For being filled to few two blocks of non-woven fabrics through cutting out；
Draw materials, make bonding powder: will gradually heat up in 75 ° of C to 400 ° of C of temperature in plateau clay input to drying oven and dry, cooling of coming out of the stove is delivered to grinder again and grinds, and inputs afterwards and sieves to sieving machine, stays 400 mesh powder stand-by as bonding powder；
In agitator, add diatomite 60%, bonding powder 40%, water in right amount, reconcile into slurry standby；
Open and flat layer of non-woven fabric, by in standby slurry input to air pressure ejector, adjustment shower nozzle covering of the fan spray angle is directed at non-woven fabrics in the range of 70 ° and sprays, watch-dog Sensor monitoring cloth cover the uniform thickness sprayed so that it is thickness is between 0.5 to 1.7mm；
By another layer of non-textile mulch, on the non-woven fabrics with slurry spray-up and sizing becomes fabric swatch；
Fabric swatch input is carried out electric heating drying, the shaping of rolling plates face to electric roller press, makes the core body material of filtration core；
It is cut out making filtration core body by user's requirement to cutting device by the input of core body material.Preferably, described watch-dog sensor is wi-sun junction sensor, the slurry thickness parameter being sprayed on non-woven fabrics is sent to the programme-controlled of workshop by the network of wi-sun node by sensor, by the spray rate of programme-controlled real-time control air pressure ejector and sprinkling covering of the fan angle.
Preferably, described electric roller press is a kind of function whole set equipment with electric heating drying, roll-in shaping, wherein, described electric heating drying is to be dried in the temperature range of 65 ° of C to 95 ° of C of temperature by fabric swatch, the drying parameter of its fabric swatch is sent to the programme-controlled of workshop by the Zigbee node temperature sensor being arranged on electric roller press two ends, by programme-controlled real-time control electric heating temperature.
Preferably, described fabric swatch is non-woven fabrics with material, and it is 200cm that its maximum cuts out wide cut, and it is 2cm that minimum cuts out a piece of cloth in a way with the minimum material to make two or more articles of clothing area, wherein selects the number of plies of cloth no less than two-layer.
Preferably, described Zigbee node temperature sensor is heat sensitive sensor, and its heat parameter gathered is accepted by the temperature difference circuit module being arranged on described heat sensitive sensor end and be converted into digital signal to send extremely the most described programme-controlled.
The air filtration core body that the present invention researches and develops for dust-proof problem with kieselguhr for base stock, compared to prior art, its good effect having is apparent from: first, entirely eliminated the option utilizing activated carbon calcium as filter element, it is to avoid the sensing that selects because of material when making filtering core and the high consumptive material, high cost, the problem of environmental impact assessment difference that cause occur；According to diatomaceous characteristic, determine the formula of material for core.The technical process prepare filter element is passed a parameter by sensor by programme-controlled control air pressure ejector, non-woven fabrics is implemented spray rate and the sprinkling covering of the fan angle of slurry again, the slurry thickness in the non-woven fabrics scope of operation can be made completely the same, it is to avoid traditional handicraft is coated with product quality insecure problem that slurry inequality is brought；Programme-controlled control in real time under neat by the core of the core body sheet material of electric heating drying, adsorptivity consistent, and the reciprocating action of roll-in, number of times and rolling pressure are also dependent on programme-controlled real-time control, thus the high-quality filtering core of output.
