Description

Technical Field

[0001] This utility model relates to the field of Pall ring technology, and in particular to a polytetrafluoroethylene Pall ring structure. Background Technology

[0002] Polytetrafluoroethylene (PTFE) Pall rings are polymer compounds formed by the polymerization of tetrafluoroethylene. They possess excellent chemical stability and corrosion resistance, and are resistant to all chemicals except molten sodium and liquid fluorine. However, existing PTFE Pall ring structures have at least the following drawbacks: 1. Poor stability during use, with the internal tongues of the Pall ring prone to deformation; 2. Difficulty in positioning existing Pall rings during use. Therefore, we introduce a new PTFE Pall ring structure. Utility Model Content

[0003] The main objective of this invention is to provide a polytetrafluoroethylene Pall ring structure, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A polytetrafluoroethylene (PTFE) Pall ring structure includes a support ring structure, an outer ring structure mounted on the upper end of the support ring structure, and three outer ring structures. Each adjacent pair of outer ring structures is fixedly connected with several connecting rings. Each pair of opposite connecting rings is fixedly connected with a tongue structure. The outer surfaces of the three outer ring structures are each fitted with a first wear-resistant and corrosion-resistant layer, and the inner ring walls of the three outer ring structures are each fitted with a second wear-resistant and corrosion-resistant layer.

[0006] Preferably, the lower end of the outer ring structure at the bottom is fixedly connected with several rubber rods in an annular array, the upper end of the support ring structure has several connecting holes in an annular array, and the upper surface of the support ring structure is interlaced with several limiting screws in an annular array.

[0007] By adopting the above technical solution, several rubber plugs are respectively inserted and connected to several connecting holes, which can strengthen the connection between the outer ring structure and the support ring structure. After several limiting screws pass through the support ring structure, they are respectively inserted and connected to several rubber plugs, which can fix the connection between the support ring structure and the outer ring structure and improve stability.

[0008] Preferably, a connecting post is fixedly connected to the middle of several transverse tongue structures, and a connecting screw is inserted through the lower ends of two connecting posts, with a nut sleeved on the outer surface of the connecting screw.

[0009] By adopting the above technical solution, the upper tongue structure can be connected to the lower tongue structure by passing the connecting screw through the two connecting posts, thereby reinforcing the two tongue structures during use and improving stability.

[0010] Preferably, the nut is located on the upper part of several tongue structures.

[0011] Preferably, several rubber inserts are respectively inserted into several connecting holes, and several limiting screws are respectively threaded through the support ring structure and inserted into several rubber inserts.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By setting three outer ring structures, several tongue structures are installed between two adjacent outer ring structures. Connecting posts are fixedly connected between several horizontal tongue structures. By passing connecting screws through two connecting posts, the upper tongue structure and the lower tongue structure can be connected together to reinforce the two tongue structures during use and prevent the Pall ring structure from deforming during use.

[0014] 2. By setting several rubber inserts on the lowest outer ring structure, these rubber inserts are inserted into several connecting holes on the support ring structure and positioned by limiting screws, thereby fixing the position of the outer ring structure and improving stability.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A polytetrafluoroethylene (PTFE) Pall ring structure includes a support ring structure 1, an outer ring structure 2 installed on the upper end of the support ring structure 1, three outer ring structures 2 are provided, and several connecting rings 3 are fixedly connected between each pair of adjacent outer ring structures 2, and a tongue structure 4 is fixedly connected between each pair of opposite connecting rings 3, a first wear-resistant and corrosion-resistant layer 5 is installed on the outer surface of each of the three outer ring structures 2, and a second wear-resistant and corrosion-resistant layer 6 is installed on the inner ring wall of each of the three outer ring structures 2.

[0025] In this embodiment, the lower end of the outer ring structure 2 is fixedly connected with several rubber rods 7 in an annular array, the upper end of the support ring structure 1 has several connecting holes 8 in an annular array, and the upper surface of the support ring structure 1 is interlaced with several limiting screws 9 in an annular array; the several rubber rods 7 are interlaced with several connecting holes 8 respectively, and the several limiting screws 9 pass through the support ring structure 1 and are interlaced with several rubber rods 7 in a threaded connection.

[0026] The above scheme involves several rubber rods 7 being inserted into several connecting holes 8, which strengthens the connection between the outer ring structure 2 and the support ring structure 1. Several limiting screws 9 pass through the support ring structure 1 and are then inserted into several rubber rods 7 to position the connection between the rubber rods 7 and the connecting holes 8, thereby fixing the connection between the support ring structure 1 and the outer ring structure 2 and improving stability.

[0027] In this embodiment, a connecting post 12 is fixedly connected to the middle of several transverse tongue structures 4, and a connecting screw 10 is inserted and connected to the lower end of two connecting posts 12. A nut 11 is sleeved on the outer surface of the connecting screw 10; the nut 11 is located on the upper part of several tongue structures 4.

[0028] The above solution involves connecting the upper tongue structure 4 and the lower tongue structure 4 together by passing the connecting screw 10 through the two connecting posts 12, thereby reinforcing the use of the two tongue structures 4 and improving the stability of the tongue structures 4 during use.

[0029] It should be noted that this utility model is a polytetrafluoroethylene Pall ring structure. During use, the outer ring structure 2 and the support ring structure 1 are initially fixed by several rubber inserts 7 and connecting holes 8. This design utilizes the elasticity of the rubber inserts 7 and the fit of the connecting holes 8 to enhance the connection strength between the two. To further strengthen this connection, several limiting screws 9 are used to pass through the support ring structure 1 and then connect with the rubber inserts 7. In this way, the limiting screws 9 play a role in the precise positioning and reinforcement of the connection between the rubber inserts 7 and the connecting holes 8, improving the stability of the overall structure. The design sets three outer ring structures 2, and several tongue structures 4 are installed between two adjacent outer ring structures 2. The tongue structures 4 not only increase the lateral support of the structure, but also improve the gas-liquid exchange efficiency through their special shape design (such as tongues bent towards the ring center). Connecting posts 12 are fixedly connected between the several tongue structures 4 in the lateral direction, and the connection is achieved by connecting screws 12. The upper tongue structure 4 is connected to the lower tongue structure 4 by passing through two connecting columns 12. This reinforcement method effectively prevents the tongue structure 4 from deforming or shifting during use, thus ensuring the overall stability of the Pall ring structure. Through the above-mentioned connection and reinforcement design, the PTFE Pall ring structure can maintain high stability during use. Whether it is the connection between the outer ring structure 2 and the support ring structure 1, or the reinforcement between the tongue structures 4, the whole structure is more robust and durable. The design of the tongue structure 4 allows the gas flow and liquid flow to fully contact and exchange in the tower. Each tongue bends towards the ring center, and the positions of two adjacent windows and tongues are offset in opposite directions. This design increases the gas-liquid contact area and contact time, thereby improving the exchange efficiency. PTFE material itself has excellent corrosion resistance and temperature resistance, which enables the Pall ring structure to work stably for a long time in various harsh industrial environments. Its resistance to acid and alkali corrosion, temperature resistance and aging resistance ensure the long service life of the structure.
