Description

Technical Field

[0001] This utility model relates to the field of candle-type corrosion-resistant filter technology, and in particular to a novel liquid collection pipe support mechanism. Background Technology

[0002] As a key piece of equipment for liquid purification and corrosion prevention in chemical, environmental protection and other fields, the internal liquid collection pipe support mechanism of candle-type corrosion-resistant filters directly determines the filter's operational stability, liquid collection efficiency and corrosion resistance life. If the support mechanism cannot adapt to high corrosion resistance requirements or is inconvenient to operate, it will lead to frequent equipment failures and increased maintenance costs. Therefore, it is essential to develop a liquid collection pipe support mechanism that combines high corrosion resistance adaptability with convenient maintenance to ensure the normal operation of the filter. In the existing technology, the liquid collection pipe support of candle-type corrosion-resistant filters generally adopts a structure of welding a U-shaped support seat to the inner wall of the corrosion-resistant cylinder. The liquid collection pipe is directly supported and fixed by the U-shaped support seat. This structure can meet the basic usage requirements when dealing with flexible corrosion-resistant materials such as soft rubber lining.

[0003] However, this existing technology has two major drawbacks. First, the U-shaped support protrudes from the inner wall of the anti-corrosion cylinder, which disrupts the smoothness of the inner wall. When it is necessary to line the inner wall with a rigid PTFE sheet to improve the anti-corrosion level in actual applications, the rigid PTFE sheet cannot be bent to fit the protruding U-shaped support, thus failing to achieve effective lining. As a result, the equipment cannot meet the requirements of high anti-corrosion scenarios. Second, the support and fixing point of the liquid collection pipe is located inside the anti-corrosion cylinder. During installation, operators need to go deep into the narrow cylinder to weld the U-shaped support and fix the liquid collection pipe. This operation is difficult and inefficient. In the later maintenance, disassembling or adjusting the liquid collection pipe also requires working inside the cylinder, further increasing labor and time costs. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of liquid collection pipe support mechanism, which can meet the anti-corrosion requirements of PTFE rigid rubber sheet, facilitate installation and maintenance, and reduce production costs.

[0005] The above-mentioned utility model objective is achieved through the following technical solution:

[0006] A novel liquid collection pipe support mechanism includes a corrosion-resistant cylinder and a corrosion-resistant liquid collection pipe assembly disposed therein, as well as a corrosion-resistant support connecting pipe and a fixed flange.

[0007] A through hole is provided on the side wall of the cylinder and at the position corresponding to the tail of the anti-corrosion liquid collection pipe assembly. An outwardly extending pipe is welded into the through hole, and an outer flange is provided at the end of the pipe.

[0008] One end of the anti-corrosion support connecting pipe is connected to the tail end of the anti-corrosion liquid collection pipe assembly, and the other end passes through the connecting pipe and is connected to the fixed flange.

[0009] The fixed flange and the outer flange of the pipe are fixedly connected by fasteners.

[0010] The above technical solution moves the support and fixing points of the anti-corrosion collection pipe assembly to the outside of the cylinder: First, the cylinder does not need to have a U-shaped support welded to the inner wall; only the pipe is welded to the end of the collection pipe, ensuring a smooth inner wall and meeting the anti-corrosion requirements of the PTFE rigid rubber lining, thus solving the problem that the original structure cannot be adapted to the rigid lining. Second, after the collection pipe assembly passes through the support connecting pipe, it is fixed to the connecting pipe flange on the outside with a fixing flange, making installation and maintenance more convenient. At the same time, the overall component is anti-corrosion, compatible with candle-type anti-corrosion filters, and can also effectively reduce costs and enhance product competitiveness.

[0011] As a further technical solution of this utility model: the anti-corrosion liquid collection pipe assembly includes multiple anti-corrosion liquid collection pipe tees, and adjacent anti-corrosion liquid collection pipe tees are connected end to end.

[0012] The above technical solution uses a modular three-way series structure to form the liquid collection pipe assembly, which enables the support mechanism to flexibly adapt to different numbers and layouts of filter units, greatly enhancing the product's versatility and scalability, while simplifying the production and assembly process.

[0013] As a further technical solution of this utility model: the anti-corrosion liquid collection pipe tee at the tail end of the anti-corrosion liquid collection pipe assembly is connected to one end of the anti-corrosion support connecting pipe.

[0014] The above technical solution clarifies the direct connection between the support connecting pipe and the tail end of the liquid collection pipe assembly, establishes the starting point of the force transmission path, and ensures that the externally applied tension force can effectively and directly act on the entire liquid collection pipe assembly, thereby forming a stable and reliable cantilever support.

[0015] As a further technical solution of this utility model: the two ends of the anti-corrosion liquid collection pipe tee are respectively provided with internal threads and external threads.

[0016] The above technical solution utilizes the standardized and highly reliable connection method of internal and external threads to achieve the end-to-end connection between tees, which not only ensures the sealing of the liquid collection channel, but also makes the assembly process of the entire component simple, fast and with high connection strength.

[0017] As a further technical solution of this utility model: one end of the anti-corrosion support connecting pipe is provided with an internal thread that matches the external thread of the anti-corrosion liquid collection pipe tee; the other end is provided with an external thread that matches the central internal thread of the fixed flange.

[0018] The above technical solution defines the thread fit at both ends of the support connecting pipe, and constructs a complete and continuous thread force transmission chain from the internal liquid collection pipe to the external fixed flange, ensuring that the entire support system can be reliably tightened and locked when the external flange bolts are tightened.

[0019] As a further technical solution of this utility model: the anti-corrosion support connecting pipe is a solid structure.

[0020] By using the above technical solution, the supporting connecting pipe is limited to a solid structure, which allows it to focus on bearing tensile stress, thereby improving the structural strength and rigidity, avoiding the risk of deformation, and ensuring the stability of long-term support.

[0021] In summary, this utility model has at least one of the following beneficial technical effects:

[0022] 1. This utility model discloses a novel liquid collection pipe support mechanism, which achieves the integrity and flatness of the inner wall of the cylinder by moving the support fixing point to the outside of the cylinder and using an external flange for mechanical locking, thus meeting the process requirements of hard lining corrosion protection, and significantly facilitating installation and maintenance.

[0023] 2. This utility model discloses a novel liquid collection pipe support mechanism, which adopts a modular liquid collection pipe assembly composed of three-way connectors connected end to end, thereby enabling the support mechanism to flexibly adapt to different filter element quantities and layouts, enhancing the product's versatility and simplifying the production and assembly process.

[0024] 3. This utility model discloses a novel liquid collection pipe support mechanism, which constructs a complete and reliable force transmission chain by limiting the support connecting pipe to a solid structure and its two ends to a specific threaded fit, ensuring that the entire support system can be effectively tightened and locked when the external flange is tightened, thereby guaranteeing long-term support stability.

[0036] Example 1:

[0037] Reference Figure 1 and Figure 2This utility model discloses a novel liquid collection pipe support mechanism, comprising an anti-corrosion cylinder 1, which serves as the mounting base and is fitted with an anti-corrosion top cover 2. The inner walls of both the anti-corrosion cylinder 1 and the anti-corrosion top cover 2 are made of acid and alkali resistant anti-corrosion material. On the side wall of the anti-corrosion cylinder 1, a through hole adapted to the outer diameter of the connecting pipe is pre-drilled at the tail position of the anti-corrosion liquid collection pipe assembly 3. An outwardly extending connecting pipe is fixed within this through hole using a welding process. The connecting pipe and the anti-corrosion cylinder 1 are made of the same material to avoid electrochemical corrosion due to material differences and ensure overall anti-corrosion performance. An outer flange is integrally formed or welded at the end of the connecting pipe, with evenly distributed bolt holes on the outer flange. This connecting pipe design avoids any protruding structures on the inner wall of the anti-corrosion cylinder 1, such as traditional U-shaped support seats; it also provides a stable connection carrier for subsequent external fixing components, laying the foundation for the flatness of the inner wall of the cylinder.

[0038] Reference Figure 3 and Figure 5 The anti-corrosion liquid collection pipe assembly 3 is the core component for liquid collection. It consists of multiple anti-corrosion liquid collection pipe tees 4 connected end to end. Each anti-corrosion liquid collection pipe tee 4 is made of anti-corrosion material, and both ends are machined with standardized internal and external threads. The internal thread at one end is used to adapt to the external thread of the preceding anti-corrosion liquid collection pipe tee 4, and the external thread at the other end is used to adapt to the internal thread of the following anti-corrosion liquid collection pipe tee 4. The thread engagement achieves a quick, tight, and sealed connection between adjacent tees, effectively preventing leakage of filtered liquid at the connection gaps. At the same time, the side wall of each anti-corrosion liquid collection pipe tee 4 is provided with an interface for the anti-corrosion filter element 7. The number of anti-corrosion collection pipe tees 4 is exactly the same as the number of anti-corrosion filter elements 7, that is, each anti-corrosion filter element 7 corresponds to one anti-corrosion collection pipe tee 4, ensuring that the liquid filtered by each anti-corrosion filter element 7 can flow directly into the corresponding anti-corrosion collection pipe tee 4; multiple sets of anti-corrosion collection pipe assemblies 3 formed by tees connected in series are arranged inside the anti-corrosion cylinder 1 in the order of "assembly from the center to the outer wall in sequence, with the number decreasing from more to less", which makes full use of the space inside the cylinder and avoids interference between the components. Finally, all the filtered liquid is gathered into the main pipe of the anti-corrosion collection pipe assembly 3 through the series tee flow channels, realizing centralized collection and discharge.

[0039] Reference Figure 6The anti-corrosion support connecting pipe 5 is a key force transmission component connecting the anti-corrosion liquid collection pipe assembly 3 and the fixed flange 6. It is made of solid anti-corrosion metal material, which has higher tensile strength and structural rigidity than hollow pipes. It can effectively resist the force generated by the weight of the anti-corrosion liquid collection pipe assembly 3 and the impact of liquid, and avoid support failure due to deformation under stress. One end of the anti-corrosion support connecting pipe 5 is machined with an internal thread, which is precisely matched with the external thread of the anti-corrosion liquid collection pipe tee 4 at the tail end of the anti-corrosion liquid collection pipe assembly 3. The two are firmly connected by clockwise screwing, and there is no gap after the connection. The other end passes through the pipe in the through hole in the side wall of the anti-corrosion cylinder 1 and extends to the outside of the anti-corrosion cylinder 1. This end is machined with an external thread, which is used to match the center internal thread of the fixed flange 6 to form a stable threaded connection, providing a path for the subsequent force transmission.

[0040] Reference Figure 4 and Figure 7 The fixed flange 6 is made of the same anti-corrosion metal as the anti-corrosion cylinder 1. It has an internal thread at its center that matches the external thread on the outside of the anti-corrosion support connecting pipe 5, and bolt holes on its edges that correspond one-to-one with the bolt holes on the outer flange of the connecting pipe. During fixing, first, the internal thread at the center of the fixed flange 6 is screwed into the external thread on the outside of the anti-corrosion support connecting pipe 5 until it fits snugly against the outer flange of the connecting pipe. Then, bolts, nuts, and other fasteners are passed through the bolt holes of the fixed flange 6 and the outer flange of the connecting pipe. Tightening the nuts applies axial pressure to the fixed flange 6, which is then converted into axial tension force on the anti-corrosion support connecting pipe 5. This tension force is transmitted along the anti-corrosion support connecting pipe 5 to the anti-corrosion assembly... The anti-corrosion liquid collection pipe tee 4 at the tail end of the liquid pipe assembly 3 ultimately drives the entire anti-corrosion liquid collection pipe assembly 3 to form a stable cantilever support inside the anti-corrosion cylinder 1. In addition, the overall anti-corrosion design of the anti-corrosion cylinder 1, the anti-corrosion liquid collection pipe assembly 3, the anti-corrosion support connecting pipe 5 and the fixing flange 6 ensures that the mechanism can be fully adapted to the working environment of the candle-type anti-corrosion filter. The structure of transferring the support and fixing points to the outside of the anti-corrosion cylinder 1 not only ensures the integrity and flatness of the inner wall of the anti-corrosion cylinder 1 (it can be directly lined with PTFE rigid rubber sheet to improve the anti-corrosion level), but also completely solves the inconvenience of traditional structures that require installation and maintenance inside the cylinder, significantly reducing the difficulty of operation and improving the efficiency of operation.

[0041] The assembly and fixing process of this utility model is as follows: First, multiple anti-corrosion liquid collection pipe tees 4 are screwed together by their internal and external threaded structures at both ends to form a predetermined length of anti-corrosion liquid collection pipe assembly 3. During this process, the number of anti-corrosion liquid collection pipe tees 4 must be strictly consistent with the number of anti-corrosion filter elements 7 to be installed. After the pre-assembly of the anti-corrosion liquid collection pipe assembly 3 is completed, it is installed as a whole into the anti-corrosion cylinder 1. During installation, a specific order must be followed, that is, from the central area of ​​the filter cylinder to the outer wall, liquid collection pipe assemblies of different lengths are assembled in sequence, with the longer assemblies located in the center and the shorter assemblies located on the periphery. Corresponding to each group of anti-corrosion liquid collection pipe assemblies 3, the external thread of the last anti-corrosion liquid collection pipe tee 4 at its tail end is screwed into the internal thread of one end of an anti-corrosion support connecting pipe 5. Subsequently, the operator operates from outside the cylinder, passing the other end of the anti-corrosion support connecting pipe 5 (which has external threads processed at this end) through the connecting pipe pre-welded to the corresponding position on the side wall of the anti-corrosion cylinder 1, so that it protrudes out of the cylinder. Next, on the outside of the anti-corrosion cylinder 1, tighten the internal thread of the center hole of a fixing flange 6 to the external thread of the anti-corrosion support connecting pipe 5 extending from the nozzle. Finally, use bolts and nuts to secure the fixing flange 6 to the outer flange at the end of the nozzle. By tightening these bolts, the anti-corrosion liquid collection pipe assembly 3 can be tightened and finally fixed from the outside. Repeat the above steps to complete the installation of all anti-corrosion liquid collection pipe assemblies 3.

[0042] The implementation principle of this utility model is as follows: Based on mechanics and structural design, the core lies in constructing a force transmission path that starts from the outside and ends at the inside of the liquid collection pipe, so as to achieve stable support for the liquid collection pipe assembly and adapt to the rigid lining process. Among them, the anti-corrosion support connecting pipe 5 bears the axial transmission of force, and the fixed flange 6 and the outer flange of the pipe connecting pipe on the side wall of the anti-corrosion cylinder 1 provide a stable force base for the tensile force. When the fasteners are tightened on the outside of the anti-corrosion cylinder 1, the fixed flange 6 and the connecting pipe flange will clamp the cylinder wall, and this clamping force is converted into an axial tensile force on the anti-corrosion support connecting pipe 5. Since the anti-corrosion support connecting pipe 5 is a solid anti-corrosion pipe fitting, its tensile strength can ensure that the tensile force is effectively transmitted to the anti-corrosion liquid collection pipe tee 4 at the tail end of the anti-corrosion liquid collection pipe assembly 3, thereby tightening and firmly fixing the entire anti-corrosion liquid collection pipe assembly 3 in the predetermined position. At the same time, the internal and external threads at both ends of the anti-corrosion support connecting pipe 5 are respectively adapted to the external thread of the anti-corrosion liquid collection pipe tee 4 at the tail end and the central internal thread of the fixed flange 6, ensuring the reliability and sealing of the connection. The anti-corrosion liquid collection pipe assembly 3 is composed of multiple anti-corrosion liquid collection pipe tees 4 connected end to end, and the number of anti-corrosion liquid collection pipe tees 4 is the same as the number of anti-corrosion filter elements 7. The above-mentioned force transmission structure achieves stable support without interfering with the liquid collection channel formed by the anti-corrosion liquid collection pipe tees 4, ensuring that the liquid filtered by the anti-corrosion filter element 7 can flow normally into the anti-corrosion liquid collection pipe assembly 3. In addition, all load-bearing and fastening structures are designed on the outside of the anti-corrosion cylinder 1, and no protruding parts are set on the inner wall of the cylinder, so that the inner wall of the anti-corrosion cylinder 1 remains intact and smooth, perfectly adapting to the anti-corrosion process requirements of the PTFE rigid rubber sheet lining, directly solving the defect of the U-shaped support seat in the prior art that cannot be adapted to the rigid lining.

[0043] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
