Description

Technical Field

[0001] This utility model relates to the field of cartridge filter technology, and in particular to a novel cartridge filter machine discharge port mechanism. Background Technology

[0002] As a commonly used device in the field of liquid filtration, the rationality of the discharge port mechanism of cartridge filters directly affects the adaptability and operational stability of the equipment to different process scenarios. Therefore, optimizing the discharge port mechanism to meet diverse process requirements is of great practical necessity.

[0003] In existing technologies, the discharge port structure of cartridge filters mostly adopts a fixed form with side or bottom outlet. Although this traditional structure can meet the connection requirements of most conventional process pipelines, it is difficult to adapt flexibly when facing special processes with specific requirements for outlet orientation and height, resulting in limited equipment applicability. At the same time, the component connection method of traditional discharge port mechanism is relatively fixed and lacks modular design, which not only makes the assembly and maintenance process cumbersome, but also increases production and operation and maintenance costs. In addition, the sealing performance design of some structures is insufficient, which can easily lead to liquid leakage problems and affect the stability of the filtration process. 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 filter cartridge machine discharge port mechanism, which has the effects of adjustable direction and height, convenient installation and strong sealing.

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

[0006] A novel filter cartridge machine discharge port mechanism includes a filter cartridge perforated plate and a liquid outlet pipe assembly;

[0007] The filter element has a discharge port on its porous plate and is installed inside the cylinder;

[0008] The liquid outlet pipe assembly includes a first outlet pipe, an elbow, a second outlet pipe, and an outlet flange connected in sequence.

[0009] One end of the first outlet pipe passes through the discharge port and is sealed to it, while the other end is connected to the elbow;

[0010] The other end of the elbow is connected to the second outlet pipe;

[0011] The other end of the second outlet pipe is connected to the outlet flange.

[0012] Through the above technical solution, a modular filter cartridge machine discharge port mechanism was constructed. By using sequentially connected pipes, elbows and flanges, the discharge direction can be flexibly adjusted to meet the requirements of different process pipelines for the filter outlet orientation and discharge port height. At the same time, the continuity and sealing of the discharge channel are guaranteed, the product structure is optimized and the production cost is reduced.

[0013] As a further technical solution of this utility model: a sealing groove is provided at one end of the first outlet pipe connected to the discharge port, and an external thread is provided at the other end.

[0014] The above technical solution provides a specific sealing and connection structure for the first outlet pipe, enabling one end to reliably seal the outlet of the perforated plate, while the other end provides a foundation for subsequent detachable connection through external threads, ensuring the robustness and sealing of the component connection.

[0015] As a further technical solution of this utility model: a sealing ring is provided in the sealing groove.

[0016] By using the above technical solution, a sealing ring is installed in the sealing groove, which enhances the sealing performance between the first outlet pipe and the filter element porous plate outlet, effectively preventing liquid from leaking from this key connection under pressure, and ensuring the stability and safety of the filtration process.

[0017] As a further technical solution of this utility model: both ends of the elbow are provided with internal threads.

[0018] The above technical solution uses an elbow with internal threads at both ends, which can efficiently connect to a pipe with external threads at both ends, smoothly changing the direction of the liquid outlet pipe. It is the core component for achieving flexible and adjustable outlet orientation, while also simplifying the assembly of internal pipelines.

[0019] As a further technical solution of this utility model: both ends of the second outlet pipe are provided with external threads.

[0020] The above technical solution enables the second outlet pipe to connect smoothly to the elbow and the outlet flange, which plays a role in extending the flow channel and determining the final outlet height. Together with other threaded connection components, it forms a complete internal flow channel module that can be quickly assembled and disassembled.

[0021] As a further technical solution of this utility model: the outlet flange is connected to the discharge port flange of the filter element machine, and is detachably and fixedly connected to the outer pipe flange.

[0022] The above technical solution ensures that the outlet flange and the filter cartridge machine outlet flange are sealed together to guarantee smooth liquid flow. At the same time, it can be detachably fixed to the external pipe flange, taking into account both the connection sealing performance and the convenience of pipeline disassembly and maintenance.

[0023] In summary, this utility model has at least one of the following beneficial technical effects:

[0024] 1. This utility model discloses a novel filter cartridge machine discharge port mechanism, which, by constructing a modular discharge port mechanism consisting of a filter cartridge perforated plate and a first outlet pipe, an elbow, a second outlet pipe, and an outlet flange connected in sequence, achieves flexible adjustment of the liquid discharge direction and height, meets the process pipeline adaptation requirements, and at the same time ensures the continuity and sealing of the discharge channel, optimizes the product structure, and reduces production costs.

[0025] 2. This utility model discloses a novel filter cartridge machine discharge port mechanism, which achieves a reliable seal with the filter cartridge perforated plate discharge port by setting a sealing groove and configuring a sealing ring in the first outlet pipe, effectively preventing liquid leakage and ensuring the stability and safety of the filtration process.

[0040] Example 1:

[0041] Reference Figure 1 This utility model discloses a novel filter cartridge machine discharge port mechanism, comprising a filter cartridge perforated plate 2 and a liquid outlet pipe assembly. The filter cartridge perforated plate 2 is welded inside a cylinder 8. An upper end cap 9 is connected to the upper end of the cylinder 8, and equipment flanges are welded to the upper and lower end faces. A lower end cap 1 is connected to the lower end for temporarily storing the filtered clean liquid. The cylinder 8 is supported and fixed by support legs 15, and a lifting eye nut 13 is provided on the equipment for hoisting. The flange connection is secured using hinge bolts 14. A filter cartridge 7 is installed in the upper section of the cylinder 8. After the filter cartridge 7 is installed, a filter cartridge pressure plate 11 is pressed onto its upper end. (Refer to...) Figure 9The holes on the filter element pressure plate 11 are aligned with the ends of the filter element 7; the filter element fixing screw 12 passes through the filter element pressure plate 11 and is tightened with the filter element fixing screw 12 by the wing nut 10, as shown in the figure. Figure 7 Under the tension of the filter element fixing screw 12 and the wing nut 10, the filter element 7 is firmly fixed to the filter element porous plate 2; refer to Figure 8 The filter element porous plate 2 is provided with an interface and a discharge port 21 that are compatible with the filter element 7, so as to ensure that the liquid in the cylinder 8 can flow stably through the filter element 7 for filtration.

[0042] Reference Figure 1 The liquid outlet pipe assembly consists of a first outlet connector 3, an elbow 4, a second outlet connector 5, and an outlet flange 6 connected in sequence, forming a complete liquid outlet flow channel. (Refer to...) Figure 4 Elbow 4 is preferably a 90-degree elbow 4, and both ends of elbow 4 are provided with internal threads; see reference Figure 5 Both ends of the second outlet pipe 5 are provided with external threads; refer to Figure 6 The outlet flange 6 is equipped with internal threads.

[0043] Reference Figure 1 One end of the first outlet pipe 3 passes through the outlet 21 of the filter element porous plate 2 and is sealed to it, while the other end is securely connected to the elbow 4 via a threaded connection. The other end of the elbow 4 is threaded to the second outlet pipe 5, and the other end of the second outlet pipe 5 is threaded to the outlet flange 6. By rotating the elbow 4 and selecting second outlet pipes 5 of different lengths, the liquid outlet direction and height can be adjusted respectively. Through this modular assembly structure, the liquid outlet direction and height can be flexibly adjusted to ensure that the liquid in the lower end cap 1 is smoothly transported out of the filter through the filter element porous plate 2 and the liquid outlet pipe assembly.

[0044] Reference Figure 2 and Figure 3 The first outlet pipe 3 is connected to the discharge port 21 at one end with a sealing groove 31. A sealing ring 16 is installed in the sealing groove 31 to enhance the sealing performance and prevent liquid leakage. The other end of the first outlet pipe 3 is provided with an external thread that is precisely matched with the internal thread of the elbow 4. The outlet flange 6 is tightly connected to the discharge port flange of the filter element machine. At the same time, it adopts a detachable fixed connection with the outer pipe flange, which takes into account both the sealing of the connection and the convenience of later maintenance. The overall structure optimizes the product layout, reduces production costs, and can fully meet the adaptation needs of different process pipelines.

[0045] The working process of this utility model is as follows: At the beginning of the filtration process, the liquid to be filtered in the cylinder 8 flows through the filter element 7, completing solid-liquid separation. The filtered clean liquid collects in the lower end cap 1 to form a clean liquid zone. Subsequently, driven by system pressure, the clean liquid enters the first outlet pipe 3, which is opened on the perforated plate 2 of the filter element, through the outlet 21. After being guided by the first outlet pipe 3, the liquid enters the elbow 4 to change its flow direction, and then flows into the second outlet pipe 5. The second outlet pipe 5 smoothly delivers the liquid to the outlet flange 6, which is the end point of the entire flow channel. Finally, the liquid is transported to the external process pipeline through the sealed interface formed by the outlet flange 6 and the equipment outlet flange, completing the discharge.

[0046] The assembly process of this utility model is as follows: In the assembly stage, the filter element perforated plate 2 is first welded and fixed to the designated position inside the cylinder 8. Then, the filter element 7 is installed in the upper cavity of the cylinder 8, and the upper end of the filter element 7 is pressed and fixed to the filter element perforated plate 2 by the cooperation of the filter element pressure plate 11, the filter element fixing screw 12 and the wing nut 10. The assembly of the liquid outlet pipe assembly follows the modular principle. First, the end with the external thread of the first outlet pipe 3 is tightened and connected to the elbow 4 by thread engagement. Then, the sealing ring 16 is placed into the sealing groove 31 at the front end of the first outlet pipe 3. This pre-assembled assembly is installed from the opening at the top of the equipment, so that the front end of the first outlet pipe 3 passes through the discharge port 21 of the filter element perforated plate 2, thereby achieving sealing and positioning. Next, connect the second outlet pipe 5 to the outlet flange 6 by thread, and then tighten the other end of the second outlet pipe 5 in this assembly to the remaining port of the elbow 4 that has been installed; finally, connect the outlet flange 6 to the equipment outlet flange and fix it to the outer pipe flange by bolts, thereby completing the final installation and fixing of the entire liquid outlet pipe assembly inside the equipment.

[0047] The implementation principle of this utility model is as follows: Through modular design, the filter element perforated plate 2 is combined with the liquid outlet pipe assembly consisting of a first outlet pipe 3, an elbow 4, a second outlet pipe 5, and an outlet flange 6. The structural characteristics of the elbow 4 are used to flexibly change the liquid outlet direction. By selecting different lengths of the second outlet pipe 5 to adapt to the different process pipeline requirements for the outlet height, the problem of fixed outlet position and height in traditional structures is solved. The sealing groove 31 on the first outlet pipe 3 cooperates with the sealing ring 16 to fill the gap between the first outlet pipe 3 and the outlet 21 of the filter element perforated plate 2, forming a reliable sealing structure that effectively prevents liquid leakage under pressure and ensures the stability and safety of the filtration process. All components are connected by threaded connections. The internal threads at both ends of the elbow 4 are precisely matched with the external threads of the first outlet pipe 3 and the second outlet pipe 5, respectively. The external thread of the second outlet pipe 5 mates with the internal thread of the outlet flange 6, enabling rapid assembly and disassembly of components. Simultaneously, the detachable connection design between the outlet flange 6 and the outer pipe flange further improves maintenance convenience and reduces assembly and maintenance costs. The overall structure optimizes the product structure through reasonable component layout and connection methods, improves the equipment's adaptability to different process scenarios, and enhances product competitiveness.

[0048] 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.
