Embodiment
Below against accompanying drawing, by the description to embodiment, to the embodiment of the present invention such as involved each structure
Mutual alignment and annexation, the effect of each several part and operation principle between the shape of part, construction, each several part etc. are made further
Detailed description：
As shown in Figure 1, the present invention is a kind of powder recovering device for powder coating polyester production of resins, described
Retracting device is arranged on the top position of feed bin 1 that feeds intake, and retracting device includes recovery pipe 2, the one end of recovery pipe 2 and the feed bin that feeds intake
1 connection, the other end of recovery pipe 2 with reclaim feed bin 3 connect, in recovery pipe 2 set solenoid valve 4, solenoid valve 4 and
The control unit 5 of the aperture size of solenoid valve 4 can be controlled to connect, powder time can be measured by being additionally provided with recovery pipe 2
The dust measurement 6 of receipts amount size, described dust measurement 6 is connected with control unit 5, and retracting device also includes blower fan 7.It is logical
Said structure setting is crossed, when delivering the powder stocks such as PTA, PIA, ADA into the feed bin that feeds intake, powder is produced in the feed bin that feeds intake
Dirt, at this moment, opens blower fan, dust is drawn onto in recovery pipe by blower fan from the feed bin that feeds intake, and is then transported to again in recovery feed bin.
During this, when starting to feed intake, blower fan is opened, the aperture of now control unit control solenoid valve is 100%, works as dust
When amount increases, control unit can automatically adjust solenoid valve and turn aperture down automatically, until Dust Capacity reaches a perseverance of setting
Definite value.Such structure, for the powder of different specific weight, can measure its Dust Capacity by measuring instrument, and measurement data is anti-
Control unit is fed to, the aperture regulation of solenoid valve is then controlled by control unit.In the retracting device course of work, dust
Amount is bigger, and the aperture regulation of solenoid valve is obtained smaller by control unit, so that it is guaranteed that different specific weight Dust Capacity is attained by and set
A fixed steady state value.Therefore, retracting device of the present utility model, can ensure that the amount of powder reclaimed from the feed bin that feeds intake is protected all the time
Steady state value is held, so as to effectively reclaim the powder with different specific weight, the versatility of retracting device is improved.
Described blower fan 7 is arranged in recovery pipe 2, and blower fan 7 is arranged between solenoid valve 4 and dust measurement 6
Recovery pipe 2 on, described blower fan 7 is with that can control the control unit 5 of the start and stop of blower fan 7 and air force to be connected.Blower fan is set
Put in recovery pipe, and the start and stop of blower fan and air force are all controlled by control unit 5, so, when needing retracting device
During work, blower fan work is opened by control unit, and as needed, suitable size is arrived into air quantity regulation.Then, blower fan is by powder
Dirt is drawn onto in recovery pipe from the feed bin that feeds intake, and is then transported to again in recovery feed bin, is realized that dust is effectively reclaimed.
