Description

Technical Field

[0001] The invention relates to the technical field of candle filter application, in particular to a composite filter bag with a soft skeleton. Background Art

[0002] Candle filtration is a relatively advanced, safe, efficient and pollution-free new filtering method. Candle filters have the characteristics of high efficiency and energy saving, closed and high precision, easy maintenance, safety and reliability, and a high degree of automation. They can be widely used in solid-liquid separation and filtration in industries such as petroleum, plastics, electroplating, chemicals, ceramics, pharmaceuticals, and sugar making.

[0003] At present, the filter element of the candle filter is composed of a six-plus-one frame plus a single-layer filter bag. Since the filter cloth is tightly attached to the frame, the opening rate of the frame punching plate directly affects the filter area. The actual filter area is only about 30% of the filter area of ​​the filter cloth, which in turn affects its filtering effect and often troubles users. Summary of the invention

[0004] The purpose of the present invention is to provide a composite filter bag with a soft frame to solve the problem raised in the above background technology that since the filter cloth is tightly attached to the frame, the opening rate of the frame punching plate directly affects the filtration area, and the actual filtration area is only about 30% of the filtration area of ​​the filter cloth.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a composite filter bag with a soft skeleton, comprising a plum blossom-shaped support skeleton, the outer side of the plum blossom-shaped support skeleton is provided with a soft skeleton filter bag, the interior of the soft skeleton filter bag is sequentially provided with a filter layer filter cloth and a soft skeleton support layer from the outside to the inside, and the outer wall of the soft skeleton support layer touches the inner wall of the filter layer filter cloth.

[0006] Preferably, a cylindrical inner frame is arranged at the center position inside the plum blossom-shaped support frame, an equally spaced cylindrical outer frame is arranged inside the plum blossom-shaped support frame outside the cylindrical inner frame, and an external thread is arranged on the outer wall of the top of the plum blossom-shaped support frame.

[0007] Preferably, six groups of the cylindrical exoskeletons are provided, and the angle between adjacent cylindrical exoskeletons is sixty degrees.

[0008] Preferably, the outer wall on one side of the cylindrical outer frame all touches the inner wall of the plum blossom-shaped supporting frame, and the outer wall on the other side of the cylindrical outer frame all touches the outer wall of the cylindrical inner frame.

[0010] Preferably, the cylindrical outer frame and the cylindrical inner frame are both configured as cylindrical structures, and the diameter of the cylindrical outer frame is greater than the diameter of the cylindrical inner frame.

[0011] Preferably, the inner diameter of the filter cloth of the filter layer is equal to the outer diameter of the soft skeleton support layer, and the soft skeleton support layer and the filter cloth of the filter layer are both arranged in a cylindrical structure.

[0012] Compared with the prior art, the beneficial effects of the present invention are: the composite filter bag with a self-contained soft skeleton not only increases the filtration area of ​​the composite filter bag when in use, but also achieves the purpose of high-efficiency filtration, and increases the utilization rate of the filter cloth in the filter layer, thereby greatly improving the filtration flow and filtration efficiency;

The soft skeleton support layer is a felt-like, sponge-like material that can penetrate liquid, thereby increasing the filtration area of ​​the composite filter bag when in use;

[0014] (2) When the liquid flows through the candle filter, it is first filtered by the filter cloth of the filter layer, then by the soft skeleton support layer, and finally enters the inner side of the plum blossom support skeleton, thereby achieving the purpose of high-efficiency filtration;

[0015] (3) By increasing the filtration flow channels while improving the filtration effect, the utilization rate of the filter cloth in the filtration layer is increased, thereby greatly improving the filtration flow and filtration efficiency, and the filtration efficiency is increased by more than 23%-80%.

[0022] See also Figure 1-Figure 4 , an embodiment of the present invention: a composite filter bag with a self-contained soft skeleton, comprising a plum blossom-shaped support skeleton 1, a cylindrical inner skeleton 103 is arranged at the center of the plum blossom-shaped support skeleton 1, and an equidistant cylindrical outer skeleton 102 is arranged inside the plum blossom-shaped support skeleton 1 outside the cylindrical inner skeleton 103, and six groups of cylindrical outer skeletons 102 are arranged, and the angle between adjacent cylindrical outer skeletons 102 is sixty degrees;

[0023] The outer wall of one side of the cylindrical outer frame 102 touches the inner wall of the plum blossom-shaped support frame 1, and the outer wall of the other side of the cylindrical outer frame 102 touches the outer wall of the cylindrical inner frame 103;

[0024] There are six cylindrical outer frames 102 and one cylindrical inner frame 103, and the six cylindrical outer frames 102 and one cylindrical inner frame 103 are combined to form a six plus one frame;

[0025] The cylindrical outer frame 102 and the cylindrical inner frame 103 are both configured to be cylindrical structures, and the diameter of the cylindrical outer frame 102 is greater than the diameter of the cylindrical inner frame 103;

[0026] An external thread 101 is provided on the outer wall of the top of the plum blossom-shaped support frame 1, and a soft skeleton filter bag 2 is provided on the outer sleeve of the plum blossom-shaped support frame 1. The inside of the soft skeleton filter bag 2 is sequentially provided with a filter layer filter cloth 202 and a soft skeleton support layer 201 from the outside to the inside, and the outer wall of the soft skeleton support layer 201 touches the inner wall of the filter layer filter cloth 202;

[0027] The inner diameter of the filter cloth 202 of the filter layer is equal to the outer diameter of the soft skeleton support layer 201 , and both the soft skeleton support layer 201 and the filter cloth 202 of the filter layer are configured in a cylindrical structure.

[0028] When the embodiment of the present application is in use, firstly, a soft skeleton support layer 201 is added between the filter layer filter cloth 202 and the plum blossom-shaped support frame 1, so that the soft skeleton support layer 201 can be combined with the filter layer filter cloth 202 to form a soft skeleton filter bag 2, and the soft skeleton filter bag 2 is sleeved on the outside of the six-plus-one frame formed by the cylindrical outer frame 102 and the cylindrical inner frame 103, so as to increase the filtration area of ​​the composite filter bag. In addition, the soft skeleton support layer 201 is a felt cloth-like, sponge-like material that can penetrate liquid. When the liquid flows through the candle filter, it is first filtered by the filter layer filter cloth 202, and then flows into the soft skeleton support layer 201. Then the liquid enters the inner side of the plum blossom-shaped support frame 1 to achieve the purpose of filtering the liquid. Finally, by increasing the filtration flow channel while solving the filtration effect, the utilization rate of the filter layer filter cloth 202 can be improved, thereby greatly improving the filtration flow rate and filtration efficiency, thereby completing the use of the composite filter bag.
