Abstract
The utility model discloses a swirling airflow powder sieving device. The swirling airflow powder sieving device comprises a base and a powder sieving chamber, wherein the powder sieving chamber is arranged on the base and is provided with a sealed upper cover; a powder inlet formed in the sealed upper cover is communicated with an external powder inlet channel through a control valve; double arc partition boards are arranged inside the sealed upper cover concentrically; a sample dividing sieve is arranged in the powder sieving chamber horizontally; an air outlet pipeline connected with the air outlet of an air filter is extended into the powder sieving chamber from the bottom to be communicated with an air nozzle below the sample dividing sieve; and the power outlet pipeline formed below the powder sieving chamber is communicated with a negative pressure collection device. The swirling airflow powder sieving device has the advantages that the sample dividing sieve is convenient to replace; ultrafine powder with different particle sizes can be sieved accurately; the maximum particle size of finished fire powder can be controlled accurately; and the overall sieving device is closed negative pressure environment, so that the dust pollution generated by the sieved powder is prevented effectively, simultaneously, the pollution to Chinese medicament fine powder caused by dirt in air is prevented, and when powder is sieved by using the swirling airflow powder sieving device, the uprush of airflow plays a role in cleaning a net and the problem about sample dividing sieve blockage is also avoided.
Description
Technical field
The utility model relates to the screening plant of powder, especially relates to a kind of laboratory gyration airflow sieve powder device commonly used.
Background technology
Superfine communication technique is to be based upon on the micromeritis basis, is accompanied by the breakthrough of the updating of disintegrating process, shattering and related discipline, and occurring in succession of disintegrating apparatus and a new technology growing up.In field of traditional Chinese medicine pharmacy; Compare with the processing mode of traditional Chinese medicine; Superfine communication technique has the cost of saving, is convenient to use, increases advantages such as drug absorption rate, raising bioavilability, but in crushing process, because the surface-active and the high powder that makes of interfacial characteristics of ultra micro powder demonstrate stronger adhesiveness; Mixed powder is prone to take place to stop up the phenomenon of screen cloth when sieving, influenced the sieving rate of medicine.Be mechanical type or air-flowing type micronizer at herbal pharmaceutical industry micronizer commonly used at present; Though mix impeller classification function the average grain diameter of micro mist is reached below the 25 μ m; But there is the uneven problem of finished product grain size size, needs through sieving accurately control maximum particle diameter.Now the mixed powder used of laboratory sieves still to adopt and divides appearance a manual method of sieving, and not only dust is big, efficient is low in the sieve powder process, and sieving of the above fine powder of 200 orders often is difficult to carry out because of the network blocking problem; The ultrasonic reciprocating sieve that yet has sieve by hand to combine with ultrasonic vibrations principle, though efficient improves than rider, dust pollution and network blocking problem are not resolved at all.
Summary of the invention
The purpose of the utility model is to provide a kind of gyration airflow easy to operate, that sieve the suitable laboratory operation of powder efficient height, non-environmental-pollution to sieve the powder device.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
The described gyration airflow of the utility model sieve powder device comprises pedestal and is arranged on the sieve powder chamber that seals loam cake having on the pedestal, is opened in the powder inlet that covers in the said sealing and advances the powder passage through by-pass valve control and outside and be connected; Be provided with two circular arc dividing plates in said sealing loam cake inner concentric; Be provided with sub-sieve at said sieve powder indoor horizontal; The wind pipe that links to each other with the air cleaner air outlet is connected with the air nozzle that is arranged on the sub-sieve below after the extension of bottom, powder chamber is entered from sieving; The powder delivery pipeline that is opened in below, sieve powder chamber is connected with the negative pressure gathering-device.
Described air nozzle is the hollow pipe that is horizontally set on the sub-sieve below, on the tube wall near sub-sieve, is evenly equipped with venthole; Described wind pipe passes through the transmission mechanism driven in rotation by micro machine.
Distance h between the identical two circular arc dividing plates of said radius is 2cm.
The advantage of the utility model is that the sub-sieve replacing is convenient, can the ultra micro powder of different-grain diameter accurately be sieved, and accurately controls the maximum particle diameter of finished product micro mist; Whole screening plant is an airtight subnormal ambient; Effectively prevent to sieve the powder operation and produce the dust pollution air; Prevent again simultaneously that airborne dirt from producing pollution to the Chinese medicine micro mist; The net effect the sub-sieve blocking problem can not occur yet owing to upward dashing of air-flow played clearly during the sieve powder, and operation is very easy, is fit to very much laboratory screening Chinese medicine and various plant ultra-micropowder usefulness.
Under the effect of negative pressure gathering-device; Whole sieve powder device is in the subnormal ambient, and mixed powder to be sieved gets in the sieve powder chamber of sealing, equally in subnormal ambient through by-pass valve control under suction function; Pass sub-sieve through the pure air that air cleaner is drawn into and between two circular arc dividing plates, form the convoluted air-flow; The air-flow band the mixed powder revolution downwards, and qualified fine powder passes screen cloth and is collected from the powder delivery pipeline, and underproof meal is stayed on the sub-sieve.Adopt the sieve powder device of the utility model can sieve the above fine powder of 500 orders.
