Description

Technical Field

[0001] The utility model belongs to the technical field of air filtration, and in particular relates to a box-type filter partition structure. Background Art

[0002] In rotary dehumidifiers, air dehumidifiers, air handling units, dehumidifying air conditioning units, and constant temperature and humidity units, filters are one of the important components of the units. However, in high-pollution industries such as food and medicine that have extremely high cleanliness requirements, higher-quality box-type high-efficiency filters are needed.

[0003] The common mounting structure used in the manufacturing of rotary dehumidifiers, air dehumidifiers, air handling units, dehumidifying air conditioning units, and constant temperature and humidity units is to create a mounting frame that matches the filter frame size. This frame is then secured to the unit's corresponding filter section baffle, which is also welded in advance. The filter section baffle is then secured to the unit's chassis. The filter mounting frame is relatively expensive to manufacture due to the overlapping use of sheet metal. Furthermore, standard filter mounting frames inevitably have unresolvable joints during installation, which can lead to leakage of contaminated air and a loss of filtration efficiency in the filter section.

[0004] The Chinese patent document with publication number CN205925221U discloses an installation structure for a box-type filter in an air handling unit, including a mounting bracket and a fixed pressing component. The mounting bracket supports the bottom frame surface of the box-type filter. The fixed pressing component uses the bracket to press the upper frame of the box-type filter in a single-point manner at the four corners of the mounting bracket. The fixed pressing component simultaneously presses the upper frames of adjacent box-type filters through pressure plates and pull rods at other places outside the four corners of the mounting bracket.

[0005] In the above patents and the technical solutions commonly used in the prior art, the main part or most of the structure of the box filter is arranged on the inside of the unit. For example, the thickness of the box-type high-efficiency filter is generally 292mm, which also causes the center of gravity of the filter to be biased toward the inside of the unit, thereby causing the center of gravity of the filter baffle to shift to one side. Moreover, the more filters there are, the more unstable the center of gravity becomes, which affects the overall structural strength of the unit when the wind pressure is high. In addition, after the box filter has been used for a period of time, the accumulation of impurities will lead to a reduction in the filtering effect. Therefore, the box filter needs to be cleaned or replaced. However, the box filter is often large in size and thickness, and the box filter of the above patent solution is not convenient for one person to operate. Utility Model Content

[0006] In order to overcome the technical problems in the prior art that the box-type filter has a large size and thickness, and the center of gravity is biased towards the inside of the unit during installation, which affects the overall structural strength of the filter partition and is inconvenient for one person to disassemble and assemble, one purpose of the utility model is to provide a box-type filter partition structure. By setting a semi-concave shell and a pull rod to limit the installation position of the box-type filter, the center of gravity of the box-type filter is located on the median vertical plane of the filter partition, preventing the center of gravity from shifting and affecting the overall structural strength. At the same time, the complexity of the installation structure is simplified, so that the operator can complete the disassembly and assembly process by one person with one hand.

[0007] 4. The filter cloth of claim 1, wherein the filter cloth is attached to the filter cloth and the filter cloth is detachably connected to the filter cloth. The filter cloth is detachably connected to the filter cloth and the filter cloth is detachably connected to the filter cloth. The filter cloth is detachably connected to the filter cloth and the filter cloth is detachably connected to the filter cloth.

[0008] Only half of the box filter is located in the semi-concave shell, and the center of gravity of the box filter is located on the median vertical plane of the filter partition, thereby preventing the filter partition from being deformed due to the offset of the center of gravity, and improving the structural strength and stability of the filter partition; since the depth of the semi-concave shell is shortened, the cost and processing amount are also reduced accordingly.

[0009] Furthermore, the pull rod includes a fixed rod arranged on the filter partition and a rotating rod rotatably connected to the fixed rod at one end away from the filter partition; the hand-tightening nut is arranged on the rotating rod; the end of the fixed rod close to the filter partition is threadedly connected to two fastening nuts; the filter partition and the semi-concave shell are pressed between two adjacent fastening nuts.

[0010] When different types of box filters (mainly different thicknesses) need to be compatible with different units and usage scenarios, adaptation is performed by replacing the pull rod and the semi-concave shell so that the center of gravity of the box filter is always in the mid-vertical plane of the filter partition.

[0011] Optionally, the rotation axis of the rotation rod is arranged along the length direction of the pressure strip.

[0012] Since only half of the box filter is located in the semi-concave shell and the other half is suspended in the air, it is necessary to hold the box filter steady during disassembly and assembly to prevent it from sliding.

[0013] The box filter can be easily disassembled and assembled by loosening the hand nut and rotating the rotating rod so that it no longer contacts the box filter. This can be done by one person with one hand, making the operation simple and convenient. The installation process is the same for the reverse operation.

[0014] Optionally, the rotation axis of the rotating rod is perpendicular to the length direction of the pressure strip; at least one end of the pressure strip is provided with a U-shaped opening; and the rotating rod is optionally located in the U-shaped opening.

[0015] The hand nut is loosened, the rotating rod is rotated to make it leave the U-shaped opening, and the pressure strip is moved so that it no longer contacts the box filter, and then the filter can be disassembled and assembled.

[0016] During the operation, there is no need to completely unscrew the hand nut, which shortens the operation time. At the same time, there are no separate parts that need to be carried or placed. While holding the box filter steady with one hand, the other hand can conveniently complete the operation without the assistance of others or tools.

[0017] Specifically, the outer wall of the fixing rod is provided with two symmetrically arranged parallel notches; the parallel notches facilitate the installation and position adjustment of the fixing rod.

[0018] Preferably, a strip-shaped cavity is provided at one end of the pressure strip away from the box filter; the hand-tightening nut is located in the strip-shaped cavity; and a cut angle is provided at one end of the strip-shaped cavity close to the hand-tightening nut.

[0019] Specifically, the sealing strip is bonded to the inner bottom end of the semi-concave shell.

[0020] Specifically, the two pull rods are respectively located directly above and directly below the box filter.

[0021] Specifically, a plurality of waist-shaped through holes are provided on the pressure strip; the waist-shaped through holes are linearly arranged along the length direction of the pressure strip; and the waist-shaped through holes reduce the obstruction of the box filter without reducing the structural strength.

[0022] Specifically, there are two filter units, which are linearly arranged in a horizontal direction.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. It can be used in the application of standard and non-standard high-efficiency box filters, can solve the problem of high-efficiency filter center of gravity offset and improve production and installation efficiency, and correspondingly reduce the cost of production and manufacturing. The filtration efficiency has also been significantly improved, and the overall structural strength has been significantly improved.

[0025] 2. The pull rod can not only be used to fix the box filter, but also fix the semi-concave shell on the filter partition. When adapting to box filters of different thicknesses, they can be replaced synchronously to ensure that the box filter is always on the median vertical plane of the filter partition, which increases compatibility and facilitates adjustment according to the box filter.

[0026] 3. The pull rod is set as a fixed rod and a rotating rod. When the operator disassembles the box filter, there are no separate parts to carry and remove. While holding the box filter to prevent it from slipping, the operator can lock and remove the pressure strip with one hand. It can be completed by one person without the assistance of others or tools. BRIEF DESCRIPTION OF THE DRAWINGS
