Description

Technical Field

[0001] The utility model belongs to the technical field related to high-efficiency filters, and in particular relates to a size-fixing anti-expansion positioning platform for high-efficiency filters. Background Art

[0002] A high-efficiency filter is a device used for air purification and filtration. It is usually used in industrial production, medical and health, laboratories and other environments. Its main function is to filter particulate matter, bacteria, viruses and other harmful substances in the air to improve air quality and protect people's health.

[0003] However, the sealants for high-efficiency filter elements and frames on the market currently include general slow-curing AB glue and fast-curing AB glue with added catalyst. The slow-curing AB glue has a slow curing speed, and to seal the other frame, it is necessary to wait until the AB glue of the first frame is cured and has no fluidity before turning the filter over to seal the other side. This leads to low production efficiency, and most of the time is spent waiting for the sealant to cure. The fast-curing AB glue with added catalyst, although it has a fast curing speed and can increase production capacity, due to the addition of the catalyst, the AB glue will generate heat and expand during curing, which will cause the single-layer screw profile to expand and deform, especially the center part of the profile, which will be severely deformed due to the lack of fixing screws, which will have a greater impact on production progress and tolerance. If the size deviates seriously, the high-efficiency filter will not be able to match the ceiling keel or FFU and will be scrapped. Utility Model Content

[0004] The utility model aims to provide a high-efficiency filter size fixed anti-expansion positioning platform to solve the problem that the AB glue generates heat and expands when the catalyst is cured, which causes the single-layer screw profile to expand and deform, especially the center part of the profile. Because there are no fixing screws, it will cause serious deformation, which has a great impact on the production progress and tolerance. If the size deviation is serious, it will also cause the high-efficiency filter to be unable to match the ceiling keel or FFU and become scrapped.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-efficiency filter size-fixing anti-expansion positioning platform, comprising a positioning platform;

[0006] A high-efficiency filter is arranged at the middle position inside the positioning platform, and limit cylinders are arranged at the left and right sides of the positioning platform respectively, and a cylinder rack is arranged at the bottom of the limit cylinder. An air source is arranged at the left side of the positioning platform, and the high-efficiency filter size is fixed. The anti-expansion positioning platform is powered by an external power supply;

[0007] A limiting plate is arranged at the right side of the limiting cylinder, a limiting column is arranged at the middle position inside the limiting plate, and a pressing plate is arranged at the inner side of the limiting plate.

[0008] Preferably, a compression spring is wrapped around the outer side of the limiting column, and the pressure plate is slidably connected to the limiting column.

[0009] Preferably, a bottom plate is provided at the bottom of the limiting plate, and the bottom plate is fixedly connected to the limiting plate.

[0010] Preferably, a push rod is provided at the front side of the limiting cylinder, a connecting piece is provided at the end of the push rod, and the connecting piece is fixedly connected to the limiting plate.

[0011] Preferably, a support plate is provided at the bottom of the high efficiency filter, and a nesting piece is provided at the bottom of the support plate.

[0012] Preferably, a positioning groove is provided at the upper position of the positioning platform, the positioning groove corresponds to the nesting piece, and four supporting plate arrays are provided.

[0013] Preferably, a switch is provided below the limit cylinder, a three-way valve is provided below the switch, and the three-way valve is respectively connected to the limit cylinders on the left and right sides.

[0014] Compared with the prior art, the utility model provides a high-efficiency filter size fixed anti-expansion positioning platform, which has the following beneficial effects:

[0015] 1. Through the setting of the limit cylinder, limit plate, limit column, pressure plate, clamping spring and base plate, the connecting piece and the limit plate are fixedly connected, which makes the connection between these components more firm and reliable, and not easy to loosen or fall off, ensuring the stability and safety of equipment operation. The push rod is connected to the limit plate through the connecting piece, which can realize precise position control and adjustment, ensuring that the action of the limit cylinder achieves the expected effect, improving the accuracy and stability of the equipment, and the fixing method of the connecting piece makes the assembly and maintenance of related components easier and faster, which is conducive to daily maintenance and maintenance work, and reduces maintenance costs and time. The fixed connection method between the connecting piece and the limit plate can reduce the wear between components, extend their service life, and improve the durability and stability of the equipment. The expansion and deformation of the size is limited by the limit device, so that the size of the high-efficiency filter is always kept within the tolerance range.

[0016] 2. Through the setting of support plates, nested parts and positioning grooves, the support plate serves as the bottom support. By setting four support plates in an array, the entire high-efficiency filter can be effectively supported to ensure the stability and balance of the high-efficiency filter. It is not easy to shake or tilt during use. The four support plates set in an array can make the high-efficiency filter more evenly stressed, avoiding deformation or damage of the filter due to uneven stress. The nested parts cooperate with the positioning grooves so that the high-efficiency filter can be accurately positioned during installation and use to ensure the correct position and posture of the filter. The array setting of the support plates and the matching nested parts and positioning grooves provide good support for the stability, accuracy and maintenance of the high-efficiency filter.

[0032] In the present embodiment, the specific implementation steps of a high-efficiency filter size fixed anti-expansion positioning platform are as follows: the basic frame of the high-efficiency filter 4 is fixed on the positioning platform 1 to ensure that the frame is stable; before production, different sizes of filters are produced to set different shapes of the cylinder to ensure that the limit plate 3 is always within the tolerance range allowed by the high-efficiency filter drawing; after the filter is coated with quick-curing AB glue, it is placed in the high-efficiency filter size fixed anti-expansion positioning platform 1; by opening and closing the switch, the cylinder pushes the limit plate 3 to press the middle part of the filter single-layer locking screw profile so that the expansion deformation does not exceed the position of the limit plate 3; after the quick-curing AB glue is completely cured and no longer expands, the switch is turned off and the cylinder connection limit plate is reset to remove the high-efficiency filter.
