Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a high efficiency filter without partitions. Background Art

[0002] The partitionless high-efficiency filter uses ultra-fine glass fiber as filter material and hot melt as the separator of the filter element. It captures dust from the gas-solid two-phase flow through the porous filter material and purifies the gas. It has the advantages of small size, light weight, easy installation, stable efficiency, and uniform wind speed. It is convenient for mechanized production. The large-scale filters required for clean workshops mostly adopt the partitionless structure.

[0003] After long-term use, a large amount of dust will adhere to the inside of the partitionless high-efficiency filter, reducing the filtering effect. After long-term use of traditional partitionless high-efficiency filters, it is impossible to clean the dust or replace the filter element in time, and the entire filter needs to be replaced, which is time-consuming and labor-intensive. Utility Model Content

[0004] The utility model aims to provide a partition-free high-efficiency filter, which solves the problem that after long-term use of the traditional partition-free high-efficiency filter, dust cannot be cleaned or the filter element cannot be replaced in time, and the entire filter needs to be replaced, which is time-consuming and laborious.

[0006] Preferably, the upper and lower ends of the plastic-sprayed protective net are fixedly connected to the filter housing, and a sealant is provided at the connection between the plastic-sprayed protective net and the filter housing.

[0007] Preferably, the glass fiber paper filter material layer is a honeycomb structure, and a hot melt adhesive is provided on the surface of the glass fiber paper filter material layer.

[0008] Preferably, the top plate of the filter housing is hinged to the main body of the filter housing via a hinge, and a sealing strip 1 is provided on the outer edge of the top plate of the filter housing.

[0009] Preferably, a mounting slide rail is provided on the inner side wall of the dust collecting chamber, and mounting slide bars are correspondingly provided on the left and right outer side walls of the dust collecting drawer.

[0010] Preferably, a handle is provided on the dust collection drawer, and a second sealing strip is installed on the front sealing plate of the dust collection drawer.

[0011] Therefore, the utility model adopts a high efficiency filter without partition plate of the above structure, which has the following beneficial effects:

[0012] (1) The air can be fully filtered by setting the activated carbon adsorption layer and the glass fiber paper filter material layer. The surface of the glass fiber paper filter material layer is provided with hot melt adhesive, which can ensure that the pleat spacing between the glass fiber papers is kept the same. The glass fiber paper filter material layer is a honeycomb structure with small resistance, large ventilation volume and large dust holding capacity, which ensures efficient filtration.

The plastic spraying protective net 2 set on the front and rear sides of the filter housing 1 can not only enhance the overall strength of the filter, but also preliminarily intercept the larger floating objects brought by the airflow to prevent the glass fiber paper filter material layer 6 from being blocked. The glass fiber paper filter material layer 6 can filter small particle pollutants in the fresh air. The glass fiber paper filter material layer 6 is a honeycomb structure with low resistance and high filtration efficiency. The activated carbon has the characteristics of large specific surface area and strong adsorption.

Through the arrangement of the openable top plate, dust collection chamber, and dust collection drawer, it is convenient to disassemble and replace the filter material inside the filter housing. When the filter is used for a long time and there is a lot of dust accumulated inside, the dust collection drawer can be opened to centrally clean the dust in the filter, which is convenient for the later maintenance of the filter.
