Description

Technical Field

[0001] This utility model relates to the field of candle filter application technology, specifically a composite filter bag with a built-in soft skeleton. Background Technology

[0002] Candle filtration is a relatively advanced, safe, efficient, and pollution-free new type of filtration. Candle filters are characterized by high efficiency and energy saving, high precision sealing, simple maintenance, safety and reliability, and a high degree of automation. They can be widely used in solid-liquid separation filtration in industries such as petroleum, plastics, electroplating, chemicals, ceramics, pharmaceuticals, and sugar refining.

[0003] Currently, the filter element of a candle filter consists 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's perforated plate directly affects the filtration area. The actual filtration area is only about 30% of the filter cloth's filtration area, which in turn affects its filtration effect and often troubles users. Utility Model Content

[0004] The purpose of this invention is to provide a composite filter bag with a built-in soft skeleton, in order to solve the problem mentioned in the background art that, since the filter cloth is tightly attached to the skeleton, the opening rate of the skeleton perforated 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 objectives, the present invention provides the following technical solution: a composite filter bag with a built-in soft skeleton, comprising a plum blossom-shaped support skeleton, a soft skeleton filter bag being sleeved on the outer side of the plum blossom-shaped support skeleton, and a filter layer filter cloth and a soft skeleton support layer being arranged sequentially from the outside to the inside of the soft skeleton filter bag, wherein the outer wall of the soft skeleton support layer is in contact with the inner wall of the filter layer filter cloth.

[0006] Preferably, a cylindrical inner frame is provided at the center of the plum blossom-shaped support frame, and an equally spaced cylindrical outer frame is provided inside the plum blossom-shaped support frame outside the cylindrical inner frame. External threads are provided on the outer wall of the top of the plum blossom-shaped support frame.

[0007] Preferably, the cylindrical exoskeleton is provided in six groups, and the included angle between adjacent cylindrical exoskeletons is sixty degrees.

[0008] Preferably, the outer wall of one side of the cylindrical outer frame is in contact with the inner wall of the plum blossom-shaped support frame, and the outer wall of the other side of the cylindrical outer frame is in contact with the outer wall of the cylindrical inner frame.

[0009] Preferably, there are six cylindrical outer skeletons and one cylindrical inner skeleton, and the six cylindrical outer skeletons and one cylindrical inner skeleton are combined to form a six-plus-one skeleton.

[0010] Preferably, both the cylindrical outer skeleton and the cylindrical inner skeleton are cylindrical in shape, and the diameter of the cylindrical outer skeleton is larger than the diameter of the cylindrical inner skeleton.

[0011] Preferably, the inner diameter of the filter layer cloth is equal to the outer diameter of the soft skeleton support layer, and both the soft skeleton support layer and the filter layer cloth are configured as cylindrical structures.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the composite filter bag with its own soft skeleton not only increases the filtration area when the composite filter bag is used, but also achieves the purpose of high-efficiency filtration, and improves the utilization rate of the filter layer filter cloth, thereby greatly improving the filtration flow rate and filtration efficiency.

[0013] (1) By adding a soft skeleton support layer between the filter layer filter cloth and the plum blossom-shaped support skeleton, it can be combined with the filter layer filter cloth to form a soft skeleton filter bag. The soft skeleton filter bag is then placed on the outside of the six-plus-one skeleton formed by the cylindrical outer skeleton and the cylindrical inner skeleton. The soft skeleton support layer is a liquid-permeable material similar to felt or sponge, thereby increasing the filtration area of ​​the composite filter bag during use.

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

[0015] (3) By increasing the number of filter channels while solving the filtration effect, the utilization rate of the filter layer and filter cloth is improved, which greatly improves the filtration flow rate and filtration efficiency, and the filtration efficiency is increased by 23%-80% or more.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figures 1-4 The present invention provides an embodiment of a composite filter bag with a built-in soft skeleton, comprising a plum blossom-shaped support skeleton 1, a cylindrical inner skeleton 103 disposed at the center of the plum blossom-shaped support skeleton 1, and cylindrical outer skeletons 102 disposed at equal intervals inside the plum blossom-shaped support skeleton 1 outside the cylindrical inner skeleton 103, with six sets of cylindrical outer skeletons 102, and the included angle between adjacent cylindrical outer skeletons 102 being sixty degrees.

[0023] The outer wall of the cylindrical outer frame 102 on one side is in contact with 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 is in contact with the outer wall of the cylindrical inner frame 103.

[0024] There are six cylindrical outer skeletons 102 and one cylindrical inner skeleton 103. The six cylindrical outer skeletons 102 and one cylindrical inner skeleton 103 are combined to form a six-plus-one skeleton.

[0025] Both the cylindrical outer skeleton 102 and the cylindrical inner skeleton 103 are cylindrical in shape, with the diameter of the cylindrical outer skeleton 102 being larger than the diameter of the cylindrical inner skeleton 103.

[0026] The outer wall of the top of the plum blossom-shaped support frame 1 is provided with an external thread 101. A soft skeleton filter bag 2 is sleeved on the outer side of the plum blossom-shaped support frame 1. The soft skeleton filter bag 2 is provided with a filter layer filter cloth 202 and a soft skeleton support layer 201 in sequence from the outside to the inside. The outer wall of the soft skeleton support layer 201 is in contact with the inner wall of the filter layer filter cloth 202.

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

[0028] In this embodiment, a soft skeleton support layer 201 is first added between the filter layer filter cloth 202 and the plum blossom-shaped support frame 1 to form a soft skeleton filter bag 2. The soft skeleton filter bag 2 is then fitted onto the outside of the six-plus-one skeleton formed by the cylindrical outer skeleton 102 and the cylindrical inner skeleton 103, thereby increasing the filtration area of ​​the composite filter bag. Furthermore, the soft skeleton support layer 201 is made of a liquid-permeable material similar to felt or sponge. When the liquid flows through the candle filter, it first passes through the filter layer filter cloth 202, then flows into the soft skeleton support layer 201, and subsequently enters the inner side of the plum blossom-shaped support frame 1 to achieve the purpose of filtering the liquid. Finally, by increasing the number of filtration channels while improving the filtration effect, the utilization rate of the filter layer filter cloth 202 is increased, thereby greatly improving the filtration flow rate and filtration efficiency, thus completing the use of the composite filter bag.

[0029] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
