Description

Technical Field

[0001] The utility model relates to the field of clean rooms, in particular to an anti-corrosion structure for a purification plate in a clean room. Background Art

[0002] A clean room is a specially designed room that removes pollutants such as particulate matter, harmful air, and bacteria from the air within a certain space, and controls the indoor temperature, cleanliness, indoor pressure, air flow speed and distribution, noise, vibration, lighting, and static electricity within a certain required range.

[0003] Since the interior of the clean room has high requirements for environmental factors, the inner wall of the clean room is usually made of purification panels. The materials of existing purification panels are mostly composite panels made of color-coated panels, stainless steel, and aluminum alloy panels. Although stainless steel has excellent corrosion resistance, it does not have strong acid corrosion resistance in some chemical cleaning workshops (mainly handling corrosive chemicals such as nitric acid and hydrofluoric acid). Therefore, in order to improve the corrosion resistance of the clean room panels, the purification panels need to be treated with anti-corrosion. The current treatment method is to spray fluorocarbon on the surface of the panel. This method can play a certain role in weak acid environments, but it will still turn yellow over time. In addition, the purification panels are usually spliced ​​when installed in the clean room, and fasteners (such as connecting screws) are easily exposed outside the splicing. Because the fasteners are usually made of steel, they are easily corroded by corrosive liquids or corrosive gases, causing environmental pollution and affecting the cleanliness of the clean room. Utility Model Content

[0004] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides an anti-corrosion structure for a clean room purification panel. The anti-corrosion structure splices several anti-corrosion panels in the clean room. The anti-corrosion panels can be bonded together with the purification panels to improve the acid corrosion resistance of the purification panels. Anti-corrosion strips are provided at the outer ends of the fasteners at the splicing points of the anti-corrosion panels to prevent corrosive gases or liquids from contacting the fasteners and causing corrosion of the fasteners. This effectively improves the service life of the fasteners while ensuring the cleanliness inside the clean room.

[0005] The utility model is implemented in this way: an anti-corrosion structure for a clean room purification panel is constructed, comprising a plurality of anti-corrosion panels spliced ​​in the clean room;

[0006] Fasteners, passing through the joints of the anti-corrosion panels, are used to splice and secure multiple anti-corrosion panels in the clean room;

[0007] The anti-corrosion strip is arranged on the outer end of the fastener and is clamped on the anti-corrosion plate.

[0008] Specifically, a first connecting portion is provided at the bottom of one side of the anti-corrosion plate, and a first connecting hole is opened on the first connecting portion. A second connecting portion is provided at the top of the other side of the anti-corrosion plate, and a second connecting hole with the same diameter and corresponding position as the first connecting hole is opened on the second connecting portion. When the two anti-corrosion plates are spliced, the first connecting portion and the second connecting portion are in contact and keep the first connecting hole and the second connecting hole corresponding to each other. The fastener passes through the first connecting hole and the second connecting hole at the joint of the two anti-corrosion plates to fix the anti-corrosion plates in the clean room.

[0009] Specifically, a card slot is provided on the first connection part and / or the second connection part of the anti-corrosion plate. The card slot is provided on the plate surface of the anti-corrosion plate and is located above the first connection hole and / or the second connection hole. The anti-corrosion strip is clamped in the card slot.

[0010] Specifically, the anti-corrosion strip includes a limiting sealing portion and a clamping portion and a smooth portion arranged at both ends of the limiting sealing portion. The clamping portion matches the clamping slot and is provided with an accommodating slot for accommodating a fastener. The limiting sealing portion is adapted to the shape of the clamping portion and maintains a size larger than that of the clamping portion. The smooth portion is a chamfered corner arranged on the limiting sealing portion.

[0011] Specifically, the receiving groove of the clamping portion and the fastener are magnetically fixed.

[0012] Specifically, sealing strips are provided at the joints of the anti-corrosion plates.

[0013] Specifically, the anti-corrosion plates and anti-corrosion strips are both made of polypropylene.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] 1. Compared with spraying fluorocarbon on the surface of the purification plate, this anti-corrosion structure avoids the cleanliness of the clean room due to discoloration and yellowing of the plate by setting a spliced ​​anti-corrosion plate in the clean room. At the same time, by setting anti-corrosion strips on the outside of the fasteners at the splicing of the anti-corrosion plate, it can prevent corrosive gases or liquids from corroding the fasteners, thereby improving the service life of the fasteners and ensuring the cleanliness of the clean room.

[0016] 2. The anti-corrosion structure is convenient for splicing and fixing by setting the specific structure of the anti-corrosion plate and the anti-corrosion strip. At the same time, the anti-corrosion strip and the fastener are magnetically fixed to facilitate fixing the anti-corrosion strip on the anti-corrosion plate to avoid falling off.

[0017] 3. The anti-corrosion structure can prevent corrosive gases and liquids from flowing into the interior and contacting fasteners through the gaps in the joints by setting sealing strips at the joints of the anti-corrosion plates, causing corrosion of the fasteners and affecting the service life and internal cleanliness.

[0025] The technical solution of the present invention will be further described in detail below through specific embodiments and in combination with the accompanying drawings. It should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention in any way. The accompanying drawings in the present invention are only used to assist in the description of the embodiments and to facilitate understanding and are not intended to limit the present invention in any way.

[0026] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions for the implementation of the present invention. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

[0027] As described in the background technology, the purification panels in existing clean rooms do not have high acid corrosion resistance and cannot be used for a long time in some cleaning workshops, which can easily cause corrosion of the purification panels and affect the internal cleanliness. In order to improve the acid corrosion resistance, some clean room floors will be paved with homogeneous through-core anti-corrosion PVC baseboards. This material is easy to break and the PVC floor boards will turn yellow after long-term use, the connection gaps will easily debond, and the floor will be easily scratched. Fluorocarbon spraying is conventionally used on walls and ceilings instead of PE spraying. This approach can play a certain role in weak acid environments, but the walls will still turn yellow over time.

[0028] For the reasons mentioned above, please refer to the attached Figure 1 ~Attached Figure 5 , the utility model provides an anti-corrosion structure for a clean room purification panel, comprising a plurality of anti-corrosion panels 1, which are spliced ​​in the clean room;

[0029] Fasteners 2, passing through the joints of the anti-corrosion plates 1, are used to splice and fix multiple anti-corrosion plates 1 in a clean room;

[0030] The anti-corrosion strip 3 is arranged on the outer end of the fastener 2 and clamped on the anti-corrosion plate 1.

[0031] In order to keep the anti-corrosion plates flush after splicing and to achieve the connection and fixation of the anti-corrosion plates, a feasible technical solution is provided here. Please refer to the attached carefully. Figure 2 and attached Figure 3 Specifically, a first connecting portion 1.1 is provided at the bottom of one side of the anti-corrosion plate 1, and a first connecting hole 1.2 is opened on the first connecting portion 1.1. A second connecting portion 1.3 is provided at the top of the other side of the anti-corrosion plate 1, and a second connecting hole 1.5 with the same diameter and corresponding position as the first connecting hole 1.2 is opened on the second connecting portion 1.3. When the two anti-corrosion plates 1 are spliced, the first connecting portion 1.1 and the second connecting portion 1.3 are in contact and keep the first connecting hole 1.2 and the second connecting hole 1.5 corresponding to each other. The fastener 2 passes through the first connecting hole 1.2 and the second connecting hole 1.5 at the joint of the two anti-corrosion plates 1 to fix the anti-corrosion plate 1 in the clean room.

[0032] Please continue to refer to the attached Figure 3 Specifically, a card slot 1.4 is provided on the first connecting portion 1.1 and / or the second connecting portion 1.3 of the anti-corrosion plate 1. The card slot 1.4 is provided on the plate surface of the anti-corrosion plate 1 and is located above the first connecting hole 1.2 and / or the second connecting hole 1.5. The anti-corrosion strip 3 is clamped in the card slot 1.4.

[0033] In order to achieve the anti-corrosion strip can be clamped on the anti-corrosion plate and fixed, here is a feasible technical solution, please refer to the attached carefully. Figure 4Specifically, the anti-corrosion strip 3 includes a limiting sealing portion 3.1 and a clamping portion 3.2 and a smooth portion 3.4 arranged at both ends of the limiting sealing portion 3.1. The clamping portion 3.2 matches the card slot 1.4 and is provided with a receiving groove 3.3 for accommodating the fastener 2. The limiting sealing portion 3.1 is adapted to the shape of the clamping portion 3.2 and maintains a size larger than the size of the clamping portion 3.2. The smooth portion 3.4 is a chamfered corner arranged on the limiting sealing portion 3.1.

[0034] In order to ensure that the anti-corrosion strip can be fixed on the protective plate at the top of the clean room to prevent it from falling off, a feasible technical solution is provided herein. Specifically, the receiving groove 3.3 of the clamping part 3.2 is magnetically fixed to the fastener 2.

[0035] In order to prevent corrosive gases or liquids from flowing into the joints of the anti-corrosion plates and coming into contact with the fasteners to cause corrosion, a sealing strip is specifically provided at the joints of the anti-corrosion plates 1 (the sealing strip can be provided as a conventional sealing strip or sealant, etc. This is an existing conventional technology and is therefore not shown in the accompanying drawings).

[0036] In order to ensure that the anti-corrosion plates and anti-corrosion strips have high acid corrosion resistance, specifically, the anti-corrosion plates 1 and anti-corrosion strips 3 are both made of polypropylene material.

[0037] The purification board can be configured as a 50mm sandwich rock wool board, and the surface layer is a 0.5mm thick PE-coated galvanized iron sheet.

[0038] Since the anti-corrosion plates and anti-corrosion strips are made of polypropylene, their supporting capacity is relatively weak, so they only need to be installed around the inner walls and top of the clean room.

[0039] When installing the anti-corrosion structure, first bring the anti-corrosion plate 1 into contact with the clean plate and keep them spliced ​​(install the sealing strip during the splicing process), then pass the fastener 2 (which can be equipped with a fastening bolt or an anchor nail) through the first connecting hole 1.2 and the second connecting hole 1.5 of the anti-corrosion plate 1 to fix it to the clean plate, then insert the clamping part 3.2 of the anti-corrosion strip 3 into the clamping groove 1.4 of the anti-corrosion plate 1, and combine the receiving groove 3.3 of the anti-corrosion strip 3 with the end of the fastener 2 to achieve magnetic fixation, and then install the anti-corrosion plate 1 on the clean plates around the inside of the clean room and on the top to complete the installation.

[0040] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
