Description

Technical Field

[0001] The utility model relates to the field of filters, in particular to a combined filter. Background Art

[0002] Filters are usually used in heat recovery sites to remove dust, particulate matter or other solid particles produced by combustion to protect heat recovery equipment and improve heat recovery efficiency.

[0003] When the existing combined filter is used in heat recovery sites, since the site environment is mostly outdoors, impurities such as road dust, rain, snow, and fallen leaves are easily sucked into the process system with the negative pressure of the incoming air, which seriously affects the normal operation of the device. It is necessary to set up louvers to block rain, snow, fallen leaves, flying birds, etc. The primary filter initially filters and intercepts larger particle impurities, and the medium-efficiency filter finely filters small molecular solid particles; the air outlet side needs to be connected to the system pipeline or device equipment, and the corresponding docking interface needs to be set up. However, since the louver, primary filter, medium-efficiency filter and air outlet are conventionally designed as dispersed independent structures, this not only increases the cost, but also occupies a large area, which is not conducive to saving site, and the filter plate frame and filter bag are production consumables, which are not convenient for disassembly and replacement.

[0004] Therefore, a combined filter has been developed that adopts an integrated design, can effectively reduce the difficulty of operation for workers, reduce floor space, quickly replace spare parts, and effectively ensure cleanliness. Utility Model Content

[0005] In order to overcome the shortcomings of existing combined filters, which occupy a large area and are not conducive to saving space, and the filter plate frame and filter bag are production consumables and are not convenient for disassembly and replacement, the utility model provides a combined filter with an integrated design, which can effectively reduce the difficulty of workers' operation, reduce the floor space, and quickly replace spare parts to effectively ensure cleanliness.

[0006] The technical implementation scheme of the utility model is: a combined filter, including a supporting frame, a guide rod, a sliding frame, a fan, a filter plate and a limiting mechanism, the front sides of the upper and lower parts of the supporting frame are connected to the guide rods, the sliding frame is slidably connected between the guide rods, the rear side of the supporting frame is connected to the fan, the filter plate is clamped inside the supporting frame, and the supporting frame is provided with a limiting mechanism for facilitating the disassembly of the filter plate.

[0007] More preferably, it further comprises louvers, and a plurality of louvers are rotatably connected to the sliding frame.

[0008] More preferably, it further includes a connecting block and a connecting frame, the right side of the louver grid is connected with a connecting block, and the connecting frames are rotatably connected between the connecting blocks.

[0009] More preferably, a push rod is provided on the connecting frame.

[0010] More preferably, the limiting mechanism includes a filter bag, a gear, a first rack, a second rack and a limiting frame, the filter bag is connected to the rear side of the filter plate, the gear is rotatably connected to the upper side of the support frame, the first rack is connected to the upper side of the sliding frame, the limiting frame is clamped on the upper side of the filter plate, the second rack is connected to the upper side of the limiting frame, and the first rack and the second rack are both meshed with the gear.

[0011] More preferably, it also includes a limiting mechanism, which includes a pulling frame, a limiting rod and a telescopic spring. The left part of the sliding frame is slidably connected with two upper and lower limiting rods, the pulling frame is connected between the front sides of the limiting rods, the limiting rods are connected to the sliding frames with telescopic springs, and the limiting rods are clamped with the supporting frame.

[0012] Compared with the prior art, the utility model has the following advantages: 1. The utility model pushes the sliding frame to move left on the guide rod, drives the first rack to move left, causes the gear to rotate, pushes the second rack to move right, and causes the limiting frame to detach from the filter plate, thereby achieving an integrated design, which can effectively reduce the difficulty of operation for workers, reduce the floor space, and quickly replace spare parts, effectively ensuring the cleaning effect.

[0013] 2. The utility model uses a pulling frame to pull the limiting rod forward to separate from the supporting frame, and the telescopic spring is stretched. When the sliding frame is reset, the pulling frame is released, and the telescopic spring rebounds, so that the limiting rod and the supporting frame are re-engaged, thereby achieving the effect of limiting the sliding frame and preventing the sliding frame from moving at will.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] A combined filter, such as Figure 1-Figure 3 As shown, it includes a support frame 1, a guide rod 2, a sliding frame 3, a louver 4, a connecting block 5, a connecting frame 6, a fan 7, a filter plate 71 and a limiting mechanism 8. The front sides of the upper and lower parts of the support frame 1 are connected to the guide rods 2, the sliding frames 3 are slidably connected between the guide rods 2, fifteen louvers 4 are rotatably connected to the sliding frames 3, the right sides of the louver 4 are connected to the connecting blocks 5, the connecting frames 6 are rotatably connected between the connecting blocks 5, and a push rod is provided on the connecting frame 6 for easy pushing. The fan 7 is connected to the rear side of the support frame 1, the filter plate 71 is clamped inside the support frame 1, and the limiting mechanism 8 is provided on the support frame 1.

[0023] like Figure 1 , Figure 4 and Figure 5 As shown, the limiting mechanism 8 includes a filter bag 81, a gear 82, a first rack 83, a second rack 84 and a limiting frame 85. The filter bag 81 is connected to the rear side of the filter plate 71, the gear 82 is rotatably connected to the upper side of the support frame 1, the first rack 83 is connected to the upper side of the sliding frame 3, the limiting frame 85 is clamped on the upper side of the filter plate 71, the second rack 84 is connected to the upper side of the limiting frame 85, and the first rack 83 and the second rack 84 are both meshed with the gear 82.

[0024] When using the utility model, first place the support frame 1 in the heat recovery place, then slide the sliding frame 3 on the guide rod 2 to the front of the filter plate 71, then push the connecting frame 6 to drive the connecting block 5 to swing, so that the louver 4 rotates on the sliding frame 3, adjust the opening and closing degree of the louver 4, and start the fan 7 after the adjustment, so that negative pressure is generated in the support frame 1 to suck air into the filter plate 71 for filtering. The louver 4 can block impurities such as road dust, rain, snow, and fallen leaves, and filter the air again through the filter bag 81. When the filter plate 71 needs to be replaced, the sliding frame 3 can be pushed to move left on the guide rod 2, driving the first rack 83 to move left, so that the gear 82 rotates, and the second rack 84 is pushed to move right, so that the limiting frame 85 is separated from the filter plate 71, and then the filter plate 71 is removed from the support frame 1, thereby playing the role of adopting an integrated design, which can effectively reduce the difficulty of workers' operation, reduce the floor space, and quickly replace spare parts, effectively ensuring the cleaning effect.

[0025] like Figure 1 and Figure 6 As shown, it also includes a limiting mechanism 9, which includes a pulling frame 91, a limiting rod 92 and a telescopic spring 93. The left part of the sliding frame 3 is slidably connected with two upper and lower limiting rods 92. The pulling frame 91 is connected between the front sides of the limiting rods 92. The limiting rods 92 are all connected to the sliding frame 3 with telescopic springs 93, and the limiting rods 92 are all clamped with the support frame 1.

[0026] By using the limiting mechanism 9 of the device, the sliding frame 3 can be limited. When the sliding frame 3 needs to be moved, the limiting rod 92 is pulled forward and separated from the supporting frame 1 by pulling the pulling frame 91, and the telescopic spring 93 is stretched. When the sliding frame 3 is reset, the pulling frame 91 is released, and the telescopic spring 93 rebounds, so that the limiting rod 92 is re-engaged with the supporting frame 1, thereby limiting the sliding frame 3 and preventing the sliding frame 3 from moving at will.
