Precoating Unit for Filter protection
pre-coating unit is used to create a powder film on the surface of the filter elements.This powder film avoids oil mist and oily particles to stick on the surface of the elements.
This powder film protects also the filter media against hot particlesby preventing these particles from touching directly to the filter media.
As a result, it minimizes the fire risk and prolongs the lifetime of the filter elements..
PreCoat Dosing unit
In order to extend the service life and effectiveness of filters in extraction systems, precoat units are often used, which periodically coat the filters with limestone powder or other precoating agents (so-called filter aids). Sticky, oily and moist media can thus not immediately stick to the filter material and filter cleaning is significantly improved.
Filter Surface Coating Material
The filters are covered with a “sacrificial layer” and thus protected from sticky residues which otherwise cannot be removed by the filter.
Recommend Coating material: limestone powder (Calcium Carbonate (CaCO3))or other precoating agents (so-called filter aids)
ACMAN Precoating/Dosing Machine-DOS-K2
Dosing container (1) with a capacity of approx. 40 liters for supply material. The filling opening is covered with the cap (2). A bag tear-off plate (3) is installed in the filling area of the device so that the supply material bags can be opened in the device when filling the dosing device. Below the bag tear-off plate there is a nozzle (4) through which compressed air is sprayed into the dosing container in intermittent operation. The feed material is raised and blown by the dosing blower (5) into the dust dosing hose (6). Air can be supplied to the dosing device via the suction opening (7).
The compressed air supply is via a connection nozzle (8) located on the lower left side of the device. The compressed air interval is controlled by a solenoid valve (9), and the flow rate is regulated by a throttle valve (10). The defined dosing mode (pre-coating, inerting, initial dosing) is set in the logic module of the switch and control unit (11), while the operating mode ("Auto/Manual/Zero") can be selected via the switch (12) Set on switches and controls. Automatic operation means: the operation of the dosing device with dust collector is blocked electrically. While in manual operation, the dosing device can be operated independently.
The feed material level is monitored by a sensor (13). When the minimum level is undershot, the "device empty" indicator light (14) lights up and activates the signaling contact in the switching device. After filling the device, the operational readiness of the device is restored by pressing the "Fill" (15) acknowledgment key. When filling the dosing device, the dosing fan is activated via the container lid push button switch (16), so that spilled dust is immediately sucked up. At the same time, the dosing of compressed air interval control is interrupted during the filling process.
In the "Inerting" operating mode, the desired dosing quantity can be set via the pause time of the dosing interval. The compressed air blowing time must always be set to a fixed 5 seconds. With the aid of the dosing program described above, the dosing pause time for the desired dosing quantity can be determined.
