Technical Field
[0001] This utility model relates to the field of detachable waterless cap type filter technology, and in particular to a detachable waterless cap type filter plate. Background Technology
[0002] As an indispensable key component in fluid pipeline systems, filters are widely used in various industrial fields such as chemical, petroleum, water treatment, food and medicine. Their main function is to filter out solid particles, impurities and suspended matter entrained in fluid media to protect the normal operation of downstream pumps, valves, instruments and other equipment, and to ensure the purity of products or media.
[0003] The core components of a traditional filter are usually one or more filter elements or filter screens. During long-term operation, these filter elements will gradually become clogged due to the continuous interception of impurities, resulting in increased filtration resistance, reduced fluid throughput, and in severe cases, complete failure. Therefore, in order to maintain the normal operation of the filtration system, the clogged filter elements must be cleaned or replaced regularly.
[0004] However, in existing technical solutions, the structural design of filters often focuses more on their sealing and pressure resistance, while neglecting the convenience of maintenance. When maintenance of the filter element is required, it is usually necessary to first shut down, depressurize, and disassemble the entire filter from the pipeline, and then disassemble its housing, flanges, and other fastening components to finally remove the internal filter element. The whole process is not only cumbersome and time-consuming, but also requires professional tools and a long system downtime, which greatly reduces the efficiency of production and maintenance and increases operating costs. In addition, some filters are designed with the fluid inlet directly facing the filter element. The direct impact of high-speed fluid can easily cause the filter media to deform and break, shortening the service life of the filter element and affecting the stability of the filtration effect.
[0005] Therefore, this utility model proposes a detachable waterless cap-type filter plate to overcome the shortcomings of the prior art. Utility Model Content
[0006] In view of the problems of existing detachable waterless cap filter plates, such as complex structure, need to disassemble the entire device for maintenance, which is cumbersome and time-consuming, and the filter material is easily damaged by direct fluid impact, affecting service life, this utility model aims to provide a detachable waterless cap filter plate with improved structure that can effectively solve the above problems.
[0007] This utility model provides a detachable waterless cap-type filter plate, including: a shell having a receiving cavity and an upper opening, a filter mechanism housed in the upper part of the receiving cavity, and a top cover that detachably seals the upper opening; and an installation mechanism that connects the top cover and the filter mechanism as one unit.
[0008] The installation mechanism includes a filter screen protection disc located between the top cover and the filter mechanism, and an upper fastener that passes through the top cover and connects to the filter screen protection disc.
[0009] Furthermore, the filter screen protection plate is equipped with a mating pin and an upper locking groove that cooperate with the upper fastener. This detachable locking structure enables the overall connection and separation of the top cover and the filter mechanism.
[0010] Preferably, the installation mechanism also includes an upper engaging groove, which is located at the top of the filter mechanism and engages with the filter screen protection disc to assist in the positioning of the filter mechanism.
[0011] Preferably, the installation mechanism further includes an internal support shaft arranged along its central axis and an internal guide column coaxially sleeved outside the internal support shaft, the internal guide column providing an outlet channel for the filtered fluid.
[0012] Preferably, the filtration mechanism is a double-layer filtration structure, including an outer layer of filter media and an inner layer of filter media.
[0013] Furthermore, the filtration mechanism also includes an external support plate for supporting the outer filter media and an internal support plate for supporting the inner filter media. The outer filter media has large filter holes, the inner filter media has small filter holes, and the inner filter media and the internal support plate are coaxially arranged inside the outer filter media and the external support plate.
[0014] Preferably, the internal support plate is connected to the bottom of the internal support shaft of the mounting mechanism.
[0015] Preferably, the detachable waterless filter plate also includes a support flange, which is connected to the bottom of the housing to provide basic support for the entire filter plate.
[0016] This utility model has the following beneficial effects: 1. This utility model, by setting up an installation mechanism consisting of upper fasteners, mating pins and locking grooves, connects the top cover and the filter mechanism into a filter assembly that can be disassembled as a whole. This solves the problem of the cumbersome disassembly of the entire equipment required for filter maintenance in the prior art, and achieves the technical effect of greatly simplifying the filter media cleaning and replacement process and significantly improving maintenance convenience and work efficiency.
[0017] 2. This utility model solves the problems of filter media being easily damaged by direct impact from high-speed fluid, having a short service life, and being prone to clogging in the prior art by setting a filter screen protection plate on the top of the filter mechanism and adopting a double-layer filter structure with a coarse outer layer and a fine inner layer inside the filter mechanism. It achieves the technical effect of effectively protecting the filter media, extending its service life, and realizing graded filtration to improve filtration accuracy and stability.
[0018] 3. This utility model solves the problems of insufficient internal structural strength and unstable fluid outflow path in some existing filters by setting a combination structure of internal guide columns and internal support shafts in the installation mechanism. It achieves the technical effect of enhancing the overall structural strength and rigidity of the device and providing a stable and smooth outlet channel for clean fluid, thereby ensuring the stable operation of the system.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0022] Example: Please refer to Figures 1 to 4 This utility model provides a detachable waterless cap type filter plate, which aims to solve the problems of complex disassembly and assembly structure, cumbersome process and easy damage to filter material by fluid impact during filter maintenance in the prior art.
[0023] like Figure 1 and Figure 2As shown, the detachable waterless cap-type filter plate includes a housing 1 as a basic supporting component, a filter mechanism 3, a top cover 2, and a mounting mechanism 4. The housing 1 has a receiving cavity and an upper opening. The filter mechanism 3 is housed in the receiving cavity of the housing 1. The top cover 2 detachably seals the upper opening of the housing 1. The mounting mechanism 4 connects the top cover 2 and the filter mechanism 3 as a whole, so that the filter assembly consisting of the top cover 2, the mounting mechanism 4, and the filter mechanism 3 can be disassembled or installed as a whole from the housing 1. A support flange 36 is fixedly connected to the bottom of the housing 1, and the support flange 36 provides basic support for the entire filter plate.
[0024] To solve the above-mentioned technical problems, the technical solution of this embodiment lies in the specific structure of the installation mechanism 4, which forms a stable and quickly detachable connection with the top cover 2 and the filter mechanism 3.
[0025] Please refer to the following carefully. Figure 3 and Figure 4 The following is a detailed description of the structure: The installation mechanism 4 includes a filter screen protection disc 44, an upper fastener 41, a mating pin 42, an upper locking groove 43, an upper locking groove 45, an internal guide column 46, and an internal support shaft 47. The filter screen protection disc 44 is located between the top cover 2 and the filter mechanism 3. The upper fastener 41 passes through the top cover 2 and is fixedly connected to the filter screen protection disc 44. By operating the upper fastener 41, the linkage locking structure formed by it, the mating pin 42, and the upper locking groove 43 enables the top cover 2 and the filter screen protection disc 44 to be quickly locked and separated. The top of the filter mechanism 3... An upper engaging groove 45 is provided, which engages with the lower end of the filter screen protection disc 44 to assist in the installation and positioning of the filter mechanism 3. The installation mechanism 4 also has an internal support shaft 47 arranged along its central axis and an internal guide column 46 coaxially sleeved outside the internal support shaft 47. This structure not only enhances the overall structural strength of the installation mechanism 4, but also provides an outlet channel for the filtered fluid. This installation mechanism 4, which integrates fastening, positioning and guiding functions, ensures the high stability of the filter assembly in the working state and the convenience of disassembly and assembly during maintenance.
[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to achieve staged filtration and improve filtration accuracy, please refer to... Figure 4The filtration mechanism 3 adopts a double-layer filtration structure, specifically including an outer filter material 31 and an inner filter material 33 disposed inside the outer filter material 31. To provide stable support for the filter material, the filtration mechanism 3 also includes an external support plate 35 for supporting the outer filter material 31 and an internal support plate 37 for supporting the inner filter material 33. The outer filter material 31 has large filter holes 32, while the inner filter material 33 has small filter holes 34 with smaller pore diameters. The inner filter material 33 and the internal support plate 37 are coaxially disposed inside the outer filter material 31 and the external support plate 35, forming a filtration channel from the outside to the inside. To further enhance structural stability and connection reliability, the internal support plate 37 is connected to the bottom of the internal support shaft 47 of the mounting mechanism 4, firmly integrating the filtration mechanism 3 and the mounting mechanism 4 together.
[0027] Working principle: The bottom of the housing 1 is connected to the supporting flange 36, providing basic support for the entire filtration device and ensuring the installation stability of the device; the top cover 2 is connected to the filtration mechanism 3 through the mounting mechanism 4; the structure of the top cover 2, the upper fastener 41, the mating pin 42 and the upper locking groove 43 realizes the locking and fixing of the top cover 2 and the filter screen protection plate 44; the upper locking groove 45 further assists in the locking and positioning of the filtration mechanism 3 and the top cover 2. The outer filter media 31 has large filter holes 32 and the inner filter media 33 has small filter holes 34. It is connected to the outer support plate 35 and the inner support plate 37 respectively. The outer support plate 35 and the inner support plate 37 provide structural support for the filter media to ensure that the filter media does not deform under fluid impact. The internal guide column 46 is connected to the internal support shaft 47, which not only provides a guide channel for the fluid, but also enhances the structural strength of the installation mechanism 4. After the fluid enters the filtration device through the channel of the shell 1, it passes through the double-layer filtration structure and the flow guiding structure in sequence to complete the filtration. The fluid first comes into contact with the outer filter material 31. The large filter holes 32 on the outer filter material 31 intercept larger impurities in the fluid, achieving preliminary filtration. The fluid that has undergone preliminary filtration then passes through the inner filter material 33. The small filter holes 34 on the inner filter material 33 intercept even smaller impurities, completing fine filtration and improving the filtration accuracy. The clean fluid, after being filtered through the double layers, flows steadily out of the device through the internal guide column 46, completing the entire filtration process. The removable maintenance principle allows for easy separation of the top cover 2 from the filter mechanism 3 by operating the upper fastener 41 and utilizing the removable engagement structure of the mating pin 42 with the upper locking groove 43 and upper locking groove 45. This allows for the removal of the outer filter media 31 and inner filter media 33 for maintenance without requiring complete disassembly of the device, significantly improving maintenance convenience. Simultaneously, the filter screen protection disc 44 protects the filter media from excessive fluid impact, extending its service life.
