Abstract
A mesh belt type filter comprises a filtering material mesh belt which is connected end to form a ring shape, and the mesh belt is driven to rotate by a driving device; a sewage nozzle is arranged above the mesh belt; a sewage tank is arranged below the screen belt; and a clear water tank is arranged between the upper layer mesh belt and the lower layer mesh belt, and clear water in the clear water tank is output and recycled through a clear water output pump. The utility model discloses an annular filtering material guipure to the sewage of different characteristics and different flow demands, and work area can be realized through the guipure of chooseing for use different length and width, as long as adjust corresponding drive arrangement's radial interval and axial length can realize on the machinery. The filter net belt rotating circularly can take away the filter matters staying on the surface of the net belt, and when the net belt is downward, the filter matters fall into the sewage tank under the action of gravity, so that the self-cleaning of the filter is realized. In addition, the flushing and back flushing of the filter are realized through the spraying device, the surface cleanliness of the mesh belt is improved, and the filtering effect is ensured.
Description
Technical Field
The utility model belongs to the technical field of printing and dyeing equipment, especially, relate to a mesh belt filter of retrieval and utilization is filtered printing and dyeing sewage.
Background
In the treatment of printing and dyeing sewage, the traditional filtering device usually uses a fixed inserting plate or a rotary drum to realize filtering, the area of the acting surface of the filter with the structure is limited, and filtered substances are easy to accumulate to influence the filtering effect, so that the filtering device is not suitable for continuous sewage filtering.
Disclosure of Invention
The utility model discloses aim at provides a filter area is big to the defect that current filter equipment exists, and the filter effect is good, has automatically cleaning ability, mesh belt filter that can continuous operation.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme:
a mesh belt filter, characterized in that: the filter material comprises a filter material mesh belt which is connected end to form a ring shape, and the mesh belt is driven to rotate by a driving device; a sewage nozzle is arranged above the mesh belt; a sewage tank is arranged below the screen belt; and a clear water tank is arranged between the upper layer and the lower layer of the mesh belt, and clear water in the clear water tank is output and recycled through a clear water output pump. Aiming at sewage with different characteristics and different flow requirements, the working area of the annular filter mesh belt can be realized by selecting mesh belts with different lengths and widths, and the radial distance and the axial length of the corresponding driving device can be mechanically adjusted. The filter net belt which rotates circularly can bring away the filter objects staying on the surface of the net belt, and when the net belt moves downwards, the filter objects fall into the sewage tank under the action of gravity, so that the self-cleaning of the filter is realized.
It is further characterized in that: the two ends of the mesh belt are provided with spray headers, and the two spray headers at the two ends respectively wash away the filter on the mesh belt leaving the working area and the filter on the mesh belt reentering the working area, so that the filtering effect is ensured, and the continuous operation of the filter is realized.
Preferably: and a spray head for spraying towards the lower mesh belt is arranged in the mesh belt. The filter mesh belt is subjected to directional spray washing through the spray header inside, filter matters accumulated on the mesh belt are further cleaned, the surface of the mesh belt is guaranteed to be clean, and the filtering effect is guaranteed.
Further: the spray header supplies water through a clean water output pump.
Preferably, the following components: a throttling valve is arranged on a clear water output pipe for supplying water to the spray header, and the water consumption of spray flushing is controlled through the throttling valve, so that the water is saved.
Preferably: the filtering material is a corrosion-resistant metal wire mesh or a nylon woven mesh so as to adapt to the treatment of printing and dyeing sewage, the filtering effect is ensured, meanwhile, the corrosion to the filter screen is prevented, and the service life of the filter is prolonged.
The utility model discloses an annular filtering material guipure to the sewage of different characteristics and different flow demands, and work area can be realized through the guipure of chooseing for use different length and width, and mechanical as long as adjust corresponding drive arrangement's radial interval and axial length can realize. The filter net belt rotating circularly can take away the filter matters staying on the surface of the net belt, and when the net belt is downward, the filter matters fall into the sewage tank under the action of gravity, so that the self-cleaning of the filter is realized. In addition, the flushing and back flushing of the filter are realized through the spraying device, the surface cleanliness of the mesh belt is improved, and the filtering effect is ensured.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, a mesh belt type filter includes a mesh belt 2 formed by corrosion-resistant metal wire mesh or nylon woven mesh which is connected end to end in a ring shape, and the mesh belt 2 is driven to rotate by a driving device. A sewage nozzle 5 is arranged above the mesh belt 2, a sewage tank 1 is arranged below the mesh belt 2, a clear water tank 7 is arranged between the upper layer mesh belt and the lower layer mesh belt 2, and clear water in the clear water tank 7 is output and recycled through a clear water output pump 6. And spray heads 3 are arranged at two ends of the mesh belt 2 and inside the mesh belt 2 downwards and are used for respectively washing and backflushing two ends of the mesh belt 2 and the mesh belt 2 at the lower layer. The spray header 3 supplies water through a clean water output pump 6, and a throttle valve 4 is arranged on a pipeline for supplying water to the spray header 3. The mesh belts 2 with different lengths and widths can meet the sewage treatment requirements of different characteristics and different flow rates.
The utility model discloses during operation, sewage spout 5 is to the last blowout sewage of continuous circulation pivoted guipure 2, and pivoted guipure 2 filters sewage, and the clear water through guipure 2 filtration falls into the clear water groove 7 in guipure 2 to export the retrieval and utilization through clear water output pump 6. Meanwhile, clear water in the clear water tank 7 is flushed from the outside to the filtered objects on the mesh belt 2 at the two ends of the mesh belt 2 through the clear water output pump 6 to the spray header 3, and is backflushed to the lower mesh belt 2 from the inside. When the mesh belt 2 rotates to automatically clean downwards, the filtering objects are further cleaned, so that the filtering effect and the continuous work of the filtering mesh belt are ensured. The sewage after scouring falls into the sewage tank 1 and is discharged.
