Abstract
The utility model discloses a metal sintering net filter, including the filter body, the filter body is circularly, the filter body includes the protection stratum reticulare, filter screen layer and enhancement stratum reticulare, the protection stratum reticulare is stainless steel sintering net and filtration pore are square filtration pore with strengthening the stratum reticulare, one side or both sides of filter screen layer are provided with the protection stratum reticulare, one side of filter screen layer is provided with a plurality of layers and strengthens the stratum reticulare, it does not set up one side of protection stratum reticulare or sets up one side at arbitrary one protection stratum reticulare not crossing the setting of stratum reticulare, the filtration pore of protection stratum reticulare all greater than the filtration pore of filter screen layer, the filtration pore of strengthening the stratum reticulare also all is greater than the filtration pore of filter screen layer, each layer of protection stratum reticulare and each layer strengthen the filtration pore size on stratum reticulare all inequality. The utility model discloses a metal sintering net filter piece long service life.
Description
Technical Field
The utility model belongs to petrochemical equipment field particularly, relates to a metal sintering net filter element.
Background
In the production process of petrochemical industry, catalyst particles in slurry are often required to be separated, the diameter of the catalyst particles to be separated is micron-sized, and a filter screen is required to achieve high filtering precision. The commonly used filter screen is a metal sintering screen filter element which is of a multilayer structure, but the conventional metal sintering screen filter element is not sintered into an integral body and has short service life.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the above-mentioned shortcoming that exists among the prior art, provide a long service life's metal sintering net filter.
In order to realize the purpose, the utility model discloses a technical scheme as follows: including the filter element body, the filter element body is circularly, the filter element body includes the protection stratum reticulare, filter screen layer and enhancement stratum reticulare, protection stratum reticulare and enhancement stratum reticulare are stainless steel sintering net and filtration pore are square filtration pore, one side or both sides of filter screen layer are provided with the protection stratum reticulare, one side of filter screen layer is provided with a plurality of layers of enhancement stratum reticulare, it sets up in one side that the protection stratum reticulare not set up in the filter screen layer or sets up one side at arbitrary one protection stratum reticulare to strengthen the stratum reticulare, the filtration pore of protection stratum reticulare all greater than the filtration pore of filter screen layer, the filtration pore size that strengthens the stratum reticulare also all greater than the filtration pore of filter screen layer, each layer of protection stratum reticulare and each layer of enhancement stratum reticulare all inequality.
In the utility model, furthermore, the filtering net layer is a stainless steel sintering net or a stainless steel fiber felt.
The utility model has the advantages that: the utility model provides a pair of metal sintering net filter, protection stratum reticulare and filtration stratum reticulare play main filtering action, strengthen the stratum reticulare and improve the life of filter. In addition, because the filter pores of the protective net layer, the filter net layer and the reinforcing net layer are different in size, the filter element body can be washed from the protective net layer to the filter net layer. The metal sintering net filter element has good filtering effect and back flushing capability.
