Abstract

The utility model relates to a gas-liquid distributor, which comprises a casing with a closed cavity, wherein an outlet is opened on the base of the casing, an inlet is opened on an upper cover, and a turntable is installed in the casing. The gas-liquid distributor is characterized in that an impeller is arranged in the casing corresponding to the inlet, and the impeller is connected with the turntable whose outer circle is provided with teeth through a driving chain. The gas-liquid distributor can push the impeller in a valve body to rotate through utilizing gas or liquid in a pipeline which is connected with the inlet, and realizes the rotation of the turntable in the valve body through the reasonably configured driving chain, and achieves the purpose of even gas or liquid supply toward the outlet through the rotation of the turntable. The gas-liquid distributor has the characteristics of reasonable structure, convenient use, free maintenance and the like.

Description

Gas-liquid allotter

Affiliated technical field

The utility model relates to a kind of gas-liquid allotter.

Background technology

Vacuum freeze drying is the new and high technology of rising in recent years, and vacuum freeze is widely used in the production of products such as food, nutriment, health products, medicine.At present, one of subject matter that vacuum freeze-drier exists is that up and down cryogenic temperature is inhomogeneous in the refrigerating chamber, the refrigerating capacity that is to say every layer of shelf is inhomogeneous, this just causes in the freezing dry process, the material on upper strata just reaches the cryogenic temperature (25 ℃-30 ℃) of regulation in a short period of time, and the material of lower floor does not also reach the cryogenic temperature of regulation, and refrigeration unit must prolong the time of refrigeration like this, increased the energy consumption of refrigeration plant on the one hand, the production cycle is prolonged.After the material in the refrigerating chamber all reaches the cryogenic temperature of regulation, will vacuumize refrigerating chamber, the material to the need drying heats simultaneously, with the rate of sublimation of accelerating to be frozen the ice that in the material.And heating process also is to conduct heat by the shelf of placing material in the refrigerating chamber.When the heat of every layer of shelf is inhomogeneous, also can cause increase drying time, energy consumption strengthens." heat distributor is freezed, adds in the freeze-drying storehouse " by name that China Intellectual Property Office was authorized on November 12nd, 2003, the patent No.: 02294448.6.This utility model is to utilize external power set, and the rotation of driven rotary baffle plate realizes distributing.When external power set, after breaking down as motor, just cause the freezing of vacuum freeze or heating more inhomogeneous, can cause very big economic loss.

The utility model content

The purpose of this utility model provides a kind of external power that need not, the gas-liquid allotter that directly utilizes gas or liquid by this device to promote its operation.

The technical solution of the utility model is: a kind of gas-liquid allotter, comprise housing with the band closed cavity, the base of this housing have outlet, on cover and have import, rotating disk is installed in housing, it is characterized in that with the import corresponding section impeller being installed in housing, impeller links to each other by the toothed rotating disk of driving-chain and cylindrical.

Angle between the center line of the import that covers on above-mentioned and the last capping is the 20-60 degree.

Import one side that covers on above-mentioned has adjustment hole.

Above-mentioned driving-chain is made up of the driving gear that links to each other with the impeller drive two-stage or the triple reduction gearing that are installed in the housing.

Above-mentioned two-stage or triple reduction gearing are made up of one or two duplicate gear.

The utility model is gas or the liquid that utilizes in the pipeline that links to each other with the import of this device, promote the impeller rotation in the valve body, by the driving-chain of reasonable disposition, realize the rotation of valve body inner rotary table, the rotation by rotating disk realizes the purpose to even steam supply of outlet or liquid.The utlity model has rational in infrastructure, easy to use, need not characteristics such as maintenance.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the right view of the utility model rotating disk;

Accompanying drawing 3 is that A of the present utility model is to view.

The specific embodiment

As Fig. 1,2, shown in 3, the housing of band closed cavity is by the base 2 that has outlet 1, have the loam cake 9 of import 10 and with base, the connector 8 that loam cake is connected as a single entity is formed, in housing, be fixed on the axle I 16 on the base 2 the toothed rotating disk 14 of cylindrical is installed, rotating disk 14 links to each other with impeller 13 by two duplicate gears that are installed in the housing, its drive path is: with driving gear 12 and gear wheel in following doubly-linked gear 5 engagements of impeller 13 for one, pinion 7 in the following doubly-linked gear and 3 engagements of the gear wheel of middle doubly-linked gear, the pinion 4 of middle doubly-linked gear and toothed rotating disk 14 engagements of cylindrical.The doubly-linked gear is rotatable under above-mentioned is installed on the II 6, and middle doubly-linked gear is rotatable to be installed on the III11, and the import 10 of opening on the loam cake 9 is corresponding with impeller 13, and the angle between the center line of import 10 and the last capping is 20-60 °, preferentially selects 45 ° for use.

During use, refrigeration or heated pressure gas by the discharge of refrigeration compressor unit, enter in this device by import 10, promote impeller 13 rotations, after above-mentioned three grades of decelerations, drive rotating disk 14 rotations, owing to have a slotted hole 17 on the rotating disk, on the base 2 corresponding with rotating disk 14, annular is evenly equipped with outlet 1, and when rotating disk 14 rotations, the pressed gas that the refrigeration compressor unit is discharged will provide refrigeration or heated pressure gas for respectively outlet 1 by slotted hole 17, by the energy that outlet 1 provides refrigeration or heating for the shelf of placing material, so just can guarantee that the refrigeration of every layer of shelf or heating are very even.When the pressure in the import 10 is excessive, can by with on the valve that links to each other of the adjustment hole 15 that covers, the pressed gas of refrigeration or heating is shunted.In order to guarantee down the rotation reliability of doubly-linked gear, middle doubly-linked gear, impeller 13, rotating disk 14, adopt polytetrafluoroethylmaterial material to make sliding bearing between the coupled axle of above-mentioned revolving part, be installed on the axle, can realize this device operate as normal under the oil-free lubrication condition, need not maintenance, simultaneously because oil-free lubrication, can guarantee to freeze or the purity of the pressed gas that heats.
