Description

a filter device

technical field

The utility model relates to a filter device for powder materials.

Background technique

When solid powder materials are transported, they are often transported by means of pneumatic transport through pipelines. Solid powder materials, such as powdered activated carbon, often contain certain impurities, such as gravel, woven bag fibers, small pieces of plastic, etc. Such impurities mixed in the powder materials will affect the equipment in contact with the powder materials, such as valves, feeders, etc. Rotating machinery such as feeders and rotary level gauges will be blocked and entangled after contact, resulting in failure of the mechanical equipment. It is necessary to disassemble and remove debris and repair and replace the mechanical equipment.

At present, the commonly used powder material pipeline filters generally only have the function of filtering impurities, which often occurs during the feeding process. Because the filter is blocked, the feeding is stopped, and the filter needs to be cleaned manually to remove the sundries and then resume. The phenomenon of feeding work. This phenomenon will lead to long feeding time, high manual work intensity, and dust leakage will often occur at the filter cleaning site, and the environment is relatively poor.

Contents of the invention

Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a device that will not block the filter, improve production efficiency, reduce work intensity and protect the environment.

In order to achieve the above object, the utility model adopts the following technical solutions:

A filter device, which comprises a feed nozzle, a filter tank, a filter plate, a blowback nozzle, a compressed air pipeline, a pulse blowback controller and a discharge nozzle, the feed nozzle is located at the lower end of the filter tank, the The filter plate is arranged inside the filter tank, and the filter plate separates the inside of the filter tank into two independent upper and lower parts. The back blowing nozzle is located on the upper part of the filter tank, and its direction is downward. The back blowing nozzle is connected to the compressed air pipeline, the compressed air pipeline passes through the wall of the filter tank and is connected to the pulse blowback controller, and the discharge nozzle is located at the upper end of the filter tank.

As a further optimization of the above solution, the filter plate includes several perforations densely distributed thereon, and the pore diameter of the perforations is smaller than the size of the impurities to be filtered out.

Further, more than three blowback nozzles are connected to the compressed air pipeline.

The beneficial effects of the utility model mainly show as:

The reverse blowing nozzle of the utility model can sweep the impurities isolated by the filter plate to the inlet of the feed nozzle to collect, avoid blocking the filter plate and the inlet of the feed nozzle, and does not need to manually remove the filter to clean the impurities, which improves the production efficiency and reduces the The working intensity is high, and it is all carried out in the tank, which will not pollute the environment.

Fig. 1 is a schematic structural view of an embodiment of the utility model.

Detailed ways

Below in conjunction with accompanying drawing and preferred embodiment the utility model is described more specifically.

As shown in Figure 1, a kind of filter device, it comprises feed pipe port 1, filter tank 2, filter plate 3, blowback nozzle 4, compressed air pipeline 7, pulse blowback controller 6 and discharge pipe mouth 5, The feed nozzle 1 is located at the lower end of the filter tank 2, the filter plate 3 is arranged inside the filter tank 2, and the filter plate 3 separates the inside of the filter tank 2 into two independent upper and lower parts, and the blowback nozzle 4 Located on the upper part inside the filter tank 2, facing downward, the blowback nozzle 4 is connected to the compressed air pipeline 7, and the compressed air pipeline 7 passes through the wall of the filter tank 2 and is connected to the pulse blowback controller 6. The nozzle 1 is located at the upper end of the filter tank 2 . The filter plate 3 includes a number of perforations 8 densely distributed thereon, and the diameter of the perforations 8 is smaller than the size of the impurities to be filtered out. Three blowback nozzles 4 are connected to the compressed air pipeline 7 . The arrows in the figure indicate the feeding, discharging and blowing directions.

In the application of this embodiment, the powder material enters the inside of the filter tank 2 through the powder material feed nozzle 1, and the filter tank 2 is separated into two independent upper and lower parts by the filter plate 3 with the perforation 8, and the two parts are connected through the perforation 8, The size of the hole diameter of the perforation 8 is set to be smaller than the size of the filtered impurities. The impurities in the powder material are isolated in the tank below the filter plate 3, and the upper part of the filter tank 2 is distributed with a blowback nozzle 4 with compressed air. The filter plate 3 is perforated, and high-pressure compressed air is blown in the opposite direction of the powder feeding direction, and the impurities blocked at the perforation 8 are blown away to ensure that the filter plate 3 is not blocked when feeding, and the blowback nozzle 4 passes through the compressed air pipe 7 and The pulse blowback controller 6 is connected, and the compressed air blowback time and interval of the reverse nozzle 4 are set by the pulse blowback controller 6 . After the feeding work is finished, the compressed air continues to blow back for a certain period of time through the reverse nozzle 4, and the impurities isolated by the filter plate 3 are blown to the feed nozzle 1 for collection. Filtration of powder materials, back blowing and unclogging after impurities block the filter plate during feeding, automatic purging of impurities and backflow to the feeding nozzle 1 after feeding, etc., can all be realized by this device.
