Description

Technical Field

[0001] This utility model relates to the field of filter box technology, and in particular to a plastic filter plate. Background Technology

[0002] Filtration is the process of purifying fluids using special devices. There are many types of filtration, and the systems used are also very wide. Solid-liquid, solid-gas, large particles, and small particles are all common. Filtration is the process in which liquid (or gas) in a suspension (or gas containing solid particles and heat) is passed through a medium under the action of a driving force or other external force, while solid particles and other substances are trapped by the filter medium, thereby separating solids and other substances from liquids (or gases).

[0003] In existing technologies, it is common to use vertically installed filter materials with the liquid to be filtered in vertical contact with the filter plate. However, this arrangement has several drawbacks: when the liquid to be filtered is rinsed, the rinsing liquid impacts the filter plate, breaking up the impurities attached to the filter pores, which still directly affects the filtration efficiency; the vertically installed filter plate results in a bulky overall filter box structure, which cannot be adapted to installation scenarios with limited space and is not easy to replace. To address the above technical shortcomings, a solution is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a plastic filter plate to solve the problem that vertically mounted filter plates cannot be adapted to installation scenarios in narrow spaces.

[0005] The objective of this utility model can be achieved through the following technical solution: A plastic filter plate includes a middle frame, a front side plate and a rear side plate respectively installed on the front and rear sides of the middle frame, a uniformly distributed filter column installed on the inner side of the front side plate, a primary filter plate that cooperates with the middle frame installed on the inner side of the front side plate, the primary filter plate having uniformly distributed filter holes, an inlet pipe for liquid entry installed at the middle of the lower end of the middle frame, and an outlet pipe for liquid discharge installed at the middle of the upper end of the middle frame; a buffer zone connected to the outlet pipe is formed between the upper ends of the middle frame and the primary filter plate, and an inlet area connected to the inlet pipe is formed between the lower ends of the middle frame and the primary filter plate.

[0006] Preferably, a locking plate connected to the middle frame is installed between the front side plate and the primary filter plate, and the locking plate has a locking hole for engaging with the filter column.

[0007] Preferably, the upper end of the liquid outlet pipe has a liquid outlet hole in the middle, the middle frame has an upper through hole at the upper end corresponding to the liquid outlet hole, and the lower end of the middle frame has a lower through hole in the middle.

[0008] Preferably, the inlet pipe has an inlet hole corresponding to the lower through hole, and the inlet hole, the lower through hole, the inlet area, the buffer zone, the upper through hole and the outlet hole constitute a filtration channel.

[0009] Preferably, a turbulence baffle is installed laterally on the inner side of the middle frame near the lower through hole. The turbulence baffle is "L" shaped and aligned with the lower through hole.

[0010] Preferably, the filter column is formed by connecting a column structure and a frustum structure. The frustum structure on the filter column matches the front section of the embedded hole, and the column structure on the filter column matches the rear section of the embedded hole. One end of the filter column extending into the embedded hole corresponds to the space between two adjacent filter holes.

[0011] The beneficial effects of this utility model are:

[0012] (1) This utility model completes the double filtration of the solution to be filtered by the vertical liquid inlet method, so that the solution and the filter structure form a multiple mixing effect. Finally, the solution is stably discharged by the vertical liquid outlet method, avoiding the problem that the impurities are broken by direct impact and continue to be discharged, which affects the filtration effect. The overall structure is a vertically set embedded method, which can effectively realize the adaptability of the entire filter plate in a narrow space. Specifically, the solution enters the middle frame through the liquid inlet pipe, completes the initial filtration by the primary filter plate, and enters the filter column through the strip filter hole. After the initial filtration, the solution is randomly impacted by the filter column that is spaced apart from the strip filter hole to complete the secondary filtration. That is, the filtration channel formed by the liquid inlet hole, the lower through hole, the liquid inlet area, the buffer zone, the upper through hole and the liquid outlet hole can complete the double filtration effect. The double filtration effect can make the solution completely filtered.

[0013] (2) On the other hand, the secondary filtration structure can be quickly disassembled by the detachable filter column. After the filter column is disassembled, the primary filter plate is immediately exposed. The blockage on the primary filter plate and the gap between the filter columns can be cleared quickly. The single-sided disassembly method can effectively solve the problem of blockage due to disassembly obstruction and site limitations, thereby reducing the impact of poor filtration.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: This example is used to solve the problem that vertically mounted filter plates cannot be adapted to installation scenarios in narrow spaces.

[0022] Please see Figure 1 - Figure 4 As shown, this embodiment is a plastic filter plate, including a middle frame 1. A front side plate 2 and a rear side plate 3 are respectively installed on the front and rear sides of the middle frame 1. Filter columns 9 are evenly distributed on the inner side of the front side plate 2. A primary filter plate 10 that cooperates with the middle frame 1 is installed on the inner side of the front side plate 2. The primary filter plate 10 has evenly distributed strip filter holes 11. An inlet pipe 4 for liquid entry is installed in the middle of the lower end of the middle frame 1, and an outlet pipe 5 for liquid discharge is installed in the middle of the upper end of the middle frame 1. A buffer zone 15 connected to the outlet pipe 5 is formed between the upper ends of the middle frame 1 and the primary filter plate 10, and an inlet area connected to the inlet pipe 4 is formed between the lower ends of the middle frame 1 and the primary filter plate 10.

[0023] A locking plate 16 connected to the middle frame 1 is installed between the front side plate 2 and the primary filter plate 10. The locking plate 16 has an embedded hole 17 that engages with the filter column 9. The upper middle part of the liquid outlet pipe 5 has a liquid outlet hole 7. The upper end of the middle frame 1 corresponding to the liquid outlet hole 7 has an upper through hole 14. The lower middle part of the middle frame 1 has a lower through hole 12. The liquid inlet pipe 4 corresponding to the lower through hole 12 has a liquid inlet hole 8. The liquid inlet hole 8, the lower through hole 12, the liquid inlet area, the buffer zone 15, the upper through hole 14 and the liquid outlet hole 7 constitute a filtration channel.

[0024] Please see Figure 1 - Figure 4As shown, before filtering the solution using this plastic filter plate, the inlet pipe 4 is used as the inlet interface and the outlet pipe 5 is used as the outlet interface to complete the installation. During filtration: the solution enters the middle frame 1 through the inlet pipe 4, is initially filtered by the primary filter plate 10, and enters the filter column 9 through the filter holes 11. After the primary filtration, the solution is randomly impacted by the filter column 9 that is spaced apart from the filter holes 11 to complete the secondary filtration. That is, the filtration channel formed by the inlet hole 8, the lower through hole 12, the inlet area, the buffer zone 15, the upper through hole 14 and the outlet hole 7 can achieve a double filtration effect, which can make the solution completely filtered.

[0025] It is particularly important to note that the solution to be filtered is filtered twice through a vertical liquid inlet method, which creates multiple mixing effects between the solution and the filter structure. Finally, the filtered solution is stably discharged through a vertical liquid outlet method, avoiding the problem of impurities being broken by direct impact and continuing to be discharged, thus affecting the filtration effect. The overall structure is installed in a vertically arranged embedding method, which can effectively achieve the adaptability of the entire filter plate in narrow spaces.

[0026] Example 2: This example is used to solve the problem of how to quickly clear scale or blockages during the filtration process.

[0027] Please see Figure 1 , Figure 3 - Figure 4 As shown, a plastic filter plate of this embodiment includes a turbulence baffle 13 horizontally installed on the inner side of the middle frame 1 near the lower through hole 12. The turbulence baffle 13 is "L" shaped and aligned with the lower through hole 12. The filter column 9 is formed by connecting a column structure and a frustum structure. The frustum structure on the filter column 9 matches the front section of the embedded hole 17, and the column structure on the filter column 9 matches the rear section of the embedded hole 17. One end of the filter column 9 extending into the embedded hole 17 corresponds to the space between two adjacent strip filter holes 11, so that the filter column 9 and the strip filter holes 11 are staggered, thereby reducing the situation where impurities are broken due to direct impact during solution filtration.

[0028] Please see Figure 3 - Figure 4 As shown, the secondary filtration structure can be quickly disassembled by the detachable filter column 9, and the primary filter plate 10 is immediately exposed after the filter column 9 is disassembled. By removing the blockage on the primary filter plate 10 and cleaning the gaps between the filter columns 9, the clogging can be quickly completed. The single-sided disassembly and assembly method can effectively solve the problem of clogging work due to disassembly and assembly obstruction and space limitations, thereby reducing the impact of poor filtration.

[0029] Combining Embodiments 1 and 2, on the one hand, the longitudinal liquid inlet method completes the dual filtration of the solution to be filtered, creating multiple mixing effects between the solution and the filter structure. Finally, the longitudinal liquid outlet method ensures the stable discharge of the filtered solution. The overall structure is a longitudinally installed design, which can effectively achieve adaptability of the entire filter plate in confined spaces. On the other hand, the single-sided disassembly method effectively solves the problem of unblocking due to disassembly obstacles and space limitations, thereby reducing the impact of poor filtration. The combined use of these two methods can effectively ensure complete filtration of the solution.

[0030] Example 3: The process and principle of this utility model:

[0031] Step 1: Before filtering the solution using this plastic filter plate, install it by using the inlet pipe 4 as the inlet interface and the outlet pipe 5 as the outlet interface.

[0032] Step 2: During filtration: The solution enters the middle frame 1 through the inlet pipe 4, is initially filtered by the primary filter plate 10, and enters the filter column 9 through the bar filter holes 11. After the initial filtration, the solution is randomly impacted by the filter column 9 that is spaced apart from the bar filter holes 11 to complete the secondary filtration. That is, the filtration channel formed by the inlet hole 8, the lower through hole 12, the inlet area, the buffer zone 15, the upper through hole 14 and the outlet hole 7 can achieve a double filtration effect.

[0033] Step 3: During unclogging: The secondary filtration structure can be quickly disassembled by the detachable filter column 9, and the primary filter plate 10 is exposed immediately after the filter column 9 is disassembled. The unclogging can be quickly completed by removing the blockage on the primary filter plate 10 and cleaning the gaps between the filter columns 9. The single-sided disassembly and assembly method can effectively solve the unclogging work caused by disassembly and assembly obstruction and space limitations.

[0034] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
