Description

Heavy metal waste liquid filter equipment

Technical Field

The utility model belongs to the technical field of waste liquid filtration, and particularly relates to a heavy metal waste liquid filtration device.

The utility model belongs to 7.2 advanced environmental protection industry important direction 7.2.1 difficult-to-treat industrial wastewater treatment and recycling technology and equipment of water pollution control equipment in 7 energy-saving environmental protection industry of strategic novel industry catalogue. Heavy metal wastewater treatment technical equipment.

Background

The heavy metal waste liquid needs to pass through a filter in the pipeline in the process of tank storage, and impurities in the heavy metal waste liquid are filtered. Because inside filter is stainless steel, and heavy metal waste liquid has certain corrosivity, through long-time filtration, soak, the filter screen of pipeline inside filter can be corroded to lose the filter action, and filter equipment is inside the pipeline, if there is great debris in the heavy metal waste liquid, like gloves, rag etc. can cover the filter screen when filtering, blocks up heavy metal waste liquid infusion pipeline, at this moment need open inside filter and clear up, influences work efficiency.

Chinese patent 200720095802.0 discloses a tubular filter screen, although the filter screen is convenient to replace or clean, the tubular filter screen needs to be matched with a special zigzag pipeline, is not matched with the existing conveying straight pipe, and the existing infusion pipeline is difficult to reform and has high reforming cost.

Chinese patent 201420650723.1 discloses a liquid infusion pipeline with filtering capability, sets up detachable filter on the pipeline, and filter includes the three-layer filter that parallel was arranged, carries out multiple filtration to chemical industry liquid, but filter still is located the pipeline, need dismantle when wasing or changing, and the work load is big.

Disclosure of Invention

In order to solve the problems, the utility model provides the heavy metal waste liquid filtering device which is corrosion-resistant, does not need frequent replacement and is not easy to block a pipeline.

The object of the utility model is achieved in the following way:

the utility model provides a heavy metal waste liquid filter equipment, includes the infusion pipeline, and the feed liquor tip of infusion pipeline sets up the filter head, and radial evenly distributed of filter head has the filtration pore, sets up the pump on the infusion pipeline, sets up the pipeline filter between filter head and the pump, and pipeline filter and filter head material are corrosion-resistant plastics in the pipeline.

The diameter of the filter holes is 3-5mm.

The filter in the pipeline is a basket filter, and the filter screen of the basket filter is made of corrosion-resistant plastic.

Compared with the prior art, the utility model has the advantages that the filter head is arranged at the liquid inlet end part of the infusion pipeline, so that not only can the impurities in the heavy metal waste liquid be filtered, but also the filtering efficiency can be ensured, if the heavy metal waste liquid contains larger impurities, such as gloves, rags and the like, the impurities are directly blocked outside the filter head of the infusion pipeline, and the problem that the filter in the pipeline is required to be disassembled and cleaned due to the blocking of the pipeline and the filter in the pipeline by the larger impurities is avoided. The pipeline inner filter material is made of corrosion-resistant plastic such as PE, so that the service life of the pipeline inner filter is prolonged, meanwhile, the cleaning and replacement difficulty of the pipeline and the pipeline inner filter is reduced, the cost is saved, and the working efficiency is improved.

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

Detailed Description

As shown in figure 1, a heavy metal waste liquid filtering device comprises an infusion pipeline 1, wherein a filtering head 2 is arranged at the liquid inlet end part of the infusion pipeline 1, filtering holes 21 are uniformly distributed in the radial direction of the filtering head 2, the filtering head 2 is sleeved with the infusion pipeline, the sleeved part is sealed well and is free from liquid leakage, a pump 3 is arranged on the infusion pipeline 1, an in-pipeline filter 4 is arranged between the filtering head 2 and the pump 3, the in-pipeline filter 4 is made of corrosion-resistant plastics, and the filtering head 2 is made of corrosion-resistant plastics.

The diameter of the filter holes 21 is 3-5mm, preferably 6 mesh. Experiments show that the 6-mesh holes can not only filter out impurities in the heavy metal waste liquid, but also ensure the filtering efficiency.

The filter 4 in the pipeline is a basket type filter, and the filter screen of the basket type filter is made of corrosion-resistant plastic.

The corrosion-resistant plastic can be Polyethylene (PE), polytetrafluoroethylene (PTFE), polyvinyl chloride (PVC) and the like.

When the heavy metal waste liquid filtering device is used for conveying heavy metal waste liquid, the filtering head 2 stretches into the heavy metal waste liquid, and impurities with larger sizes are directly blocked outside the infusion pipeline through the filtering effect of the filtering head 2, so that the problem that the pipeline or the pipeline inner filter 4 is required to be detached and cleaned due to the fact that the pipeline and the pipeline inner filter 4 are blocked by the larger impurities is avoided. The filter head 2 is uniformly distributed with filter holes 21 in radial direction, the diameter is 3-5mm, and is preferably 6 meshes, so that impurities in the heavy metal waste liquid can be filtered out, and the filtering efficiency can be ensured. The pipeline inner filter material is made of corrosion-resistant plastic such as PE, so that the service life of the pipeline inner filter is prolonged, meanwhile, the cleaning and replacement difficulty of the pipeline and the pipeline inner filter is reduced, the cost is saved, and the working efficiency is improved. In addition, through the preliminary filtration of filter head 2, through the secondary filtration of basket filter again, the heavy metal waste liquid purity degree that gets into the pump is high, has reduced the jam frequency of pump, has guaranteed the normal operating of pump, provides work efficiency.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several changes and modifications can be made without departing from the general inventive concept, and these should also be regarded as the scope of the utility model.
