Description

Atomizer

Technical field

The utility model relates to a kind of atomizer, belongs to spray drying technology.

Background technology

Atomizer is industries such as chemical industry, food, medicine, is used for the vitals of spray dryer of dry various materials.

The atomizer of prior art mainly contains two kinds, and a kind of is the atomizer that directly drives atomizing disk with high-speed electric expreess locomotive; Another kind is the atomizer that drives atomizing disk with common electric machine by gear speedup case.The latter makes difficulty because of complex structure, uses reasons such as inconvenience, is progressively substituted by the former.And directly drive the atomizer of atomizing disk by high-speed electric expreess locomotive, such as Chinese patent notification number CN2717530Y disclosed " the electronic centrifugal spray head of ultrahigh speed ", a kind of built-in motor formula atomizer that provides, although its compact conformation, volume are less, but still there are deficiencies such as the accuracy of manufacture requires to shake under high and the operating mode, noise is big in it, particularly little owing to its spouting liquid, and can only be applicable to small-sized spray drier.

Summary of the invention

The purpose of this utility model is, provides a kind of simple in structure, easy to manufacture, easy to use, can satisfy the atomizer that spray dryer maximizes and requires.

The utility model realizes that the technical scheme of its purpose is:

A kind of atomizer comprises that high-speed electric expreess locomotive, main shaft, material separating disc, perisporium have atomizing disk, casing, pedestal, cutting oil path and feed pipe that several get rid of the material hole; The high-speed electric expreess locomotive axle is connected with main shaft by shaft coupling, atomizing disk is fixed on the front end of main shaft, outside and its discharging opening that material separating disc is sleeved on main shaft communicates with atomizing disk, casing and pedestal fixed connection, its improvement is: also comprise the supporting base with Upper shaft sleeve, bottom bracket axle, oil tank and Lower shaft sleeve; High-speed electric expreess locomotive and supporting base fixed connection; Supporting base and pedestal fixed connection, bottom bracket axle and Upper shaft sleeve fixed connection, oil tank and bottom bracket axle fixed connection, Lower shaft sleeve and oil tank fixed connection, material separating disc and Lower shaft sleeve fixed connection; Main shaft is made up of enlarged diameter section and flexible reduced diameter section; Install respectively in the axis hole of Upper shaft sleeve and bottom bracket axle by upper bearing (metal) and intermediate bearing at two of the enlarged diameter section of main shaft, the lower end of the flexible reduced diameter section of main shaft by the floating bearing device in the axis hole of Lower shaft sleeve; The oil inlet pipe of cutting oil path is located at the upper end of high-speed electric expreess locomotive and communicates with gap between stator with the rotor of high-speed electric expreess locomotive; The port of export of flowline is fixed on the pedestal, and the flowline other end is fixed on the oil tank and stretches in the oil tank; Oil inlet pipe can be connected with the cutting oil circulation supply equipment with oil pump respectively with flowline; Constitute and comprise the rotor of oil inlet pipe, high-speed electric expreess locomotive and the closed cutting oil path of gap, oil tank, flowline and cutting oil circulation supply equipment between gap, bottom bracket axle and main shaft between the gap between stator, supporting base inner chamber, Upper shaft sleeve and main shaft successively; One end of feed pipe is fixed on the pedestal, and the other end and the material separating disc of feed pipe are connected.

Can understand that by above given technical scheme the utility model respectively is provided with 1 rolling bearing because its main shaft adopts three pivot and long cantilever flexible axis structures at enlarged diameter section two, top, bears radial and axial load with it; 1 floating bearing is set in the lower end of reduced diameter section or claims the gap axle sleeve, the radially amplitude of oscillation of main shaft prevents main shaft bending, distortion when starting and stopping with its restriction the utility model.And when the main shaft operate as normal, the long cantilever flexible axle can make atomizing disk make the centre of gyration by oneself.And because cutting oil of the present utility model remains and the contacting of main shaft, thereby main shaft is not only not easy to wear, and rotate very brisk flexibly.Thereby realized the purpose simple in structure, easy to manufacture, easy to use that the utility model will be realized.Especially owing to the assurance of the structural characteristics of the utility model, its spouting liquid can reach 3～50t/h, thereby satisfies the requirement that spray dryer maximizes.

The further improvement of the utility model point is:

The material hole of getting rid of of atomizing disk is provided with the wear-resisting material mouth that gets rid of.Its purpose is to avoid owing to get rid of the wearing and tearing in material hole, and causes the particle diameter super large of dried material and inconsistent.

Also comprise Oil Guide bamboo hat and oil sealing member with elastic component; The flexible reduced diameter section that the Oil Guide bamboo hat is sleeved on main shaft is connected with enlarged diameter section on the last diameter segment at position; The oil sealing member is sleeved on the reduced diameter section of main shaft, and an end of oil sealing member and the inner chamber of Oil Guide bamboo hat are halved together, and its other end is inlaid in the axis hole of oil tank.Because the existence of Oil Guide bamboo hat and oil sealing member can prevent effectively that cutting oil is dirty along main shaft, causes the consumption of environmental pollution and oil mass.Certainly adopt the mechanical sealing member of alternate manner, or main shaft cooperates with the high accuracy of axis hole etc., also can reach same purpose.

Also comprise the cooling air blast pipe; Said blast pipe is packed on the pedestal and with chassis cavity and communicates; Blast pipe can be connected with the cooling air wind regime.Its purpose obviously is to make and forms malleation in the casing, so both can cooling sprayer, can eliminate the pump-absorb action that atomizing disk rotates at a high speed again.

After technique scheme was implemented, what the utility model had was simple and reasonable, easy to manufacture, easy to use, and site environment is good, can satisfy the characteristics that spray dryer maximizes and requires, and was conspicuous.
