Description

Technical Field

[0001] The utility model relates to the technical field of filter cloths, in particular to a multi-layer composite filter cloth for filtering oily sludge. Background Art

[0002] Filter cloth is a filter medium woven from natural or synthetic fibers. It includes metal mesh or filter screen. It is mainly used for air filtration and dust removal, dust collection powder to purify the air and protect the environment in smelters, chemical plants, sugar, dye, medicine, food and other industries.

[0003] Current filter cloths are generally unable to filter oil during the filtration process, resulting in a narrow range of applications. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies of the prior art, the utility model provides a multi-layer composite filter cloth for filtering oily sludge.

[0006] (II) Technical solution

[0007] In order to achieve the above purpose, the above technical purpose of the utility model is achieved through the following technical scheme: a multi-layer composite filter cloth for filtering oily sludge, comprising a filter cloth body, a filter layer connected to the surface of the filter cloth body, a filter screen connected to the surface of the filter layer, attached fibers connected to the surface of the filter screen, filter holes provided in the filter layer, and a water permeable membrane connected in the filter holes.

[0008] Preferably, a bottom layer is fixedly connected to the bottom of the filter cloth body, the bottom layer is a fiber layer, a water filter hole and a water outlet hole are opened in the bottom layer, the water filter hole is connected to the water outlet hole, the water filter hole is horizontal, and the water outlet hole is vertical.

[0009] Preferably, a connecting line is fixedly connected inside the filter cloth body, and the connecting line alternately passes through the bottom layer and the filter cloth body.

[0010] Preferably, a water-permeable hole is provided in the filter cloth body, and the inner diameter of the water-permeable hole gradually increases first and then decreases periodically.

[0011] (III) Beneficial effects

[0012] The utility model provides a multi-layer composite filter cloth for filtering oily sludge. It has the following beneficial effects:

[0013] 1. Through the filter screen, permeable membrane and attached fibers, the oily sludge is initially filtered on the surface of the filter cloth to filter out large pieces of sludge and oil, which is convenient for the subsequent recovery of oil and sludge. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0018] As shown in the figure, a multi-layer composite filter cloth for filtering oily sludge includes a filter cloth body 1.

[0019] The filter cloth body 1 is connected to a filter layer 2 on its surface, a filter screen 3 is connected to its surface, an attached fiber 4 is connected to the filter screen 3 on its surface, a filter hole 5 is provided in the filter layer 2, and a water permeable membrane 6 is connected in the filter hole 5. The bottom of the filter cloth body 1 is fixedly connected to a bottom layer 7, which is a fiber layer, and a water filter hole 8 and a water outlet hole 9 are provided in the bottom layer 7, the water filter hole 8 is connected to the water outlet hole 9, the water filter hole 8 is horizontal, and the water outlet hole 9 is vertical. A connecting line 10 is fixedly connected to the filter cloth body 1, and the connecting line 10 alternately passes through the bottom layer 7 and the filter cloth body 1. A water permeable hole 11 is provided in the filter cloth body 1, and the inner diameter of the water permeable hole 11 is periodically gradually increasing first and then decreasing.

[0020] In summary, the oily sludge is initially filtered on the filter cloth surface through the filter screen 3, the water-permeable membrane 6 and the attached fibers 4, and large pieces of sludge and oil are filtered out, so as to facilitate the subsequent recovery of oil and sludge.
