Description

Technical Field

[0001] This utility model relates to the technical field of dust removal, specifically a filtration device for an industrial dust collector. Background Technology

[0002] Industrial dust collectors are devices used for industrial purposes to collect and absorb waste media particles, dust, smoke, oil, water, etc. generated during production and transportation. Industrial dust collectors use AC power and have relatively high power. They are generally divided into two types: mobile and stationary. They usually have a filter element installed inside.

[0003] However, in existing industrial dust collectors, dust and impurities adhering to the filter cartridges easily fall into the equipment during cleaning or replacement. This necessitates the user to clean the fallen dust again, and each cleaning requires disassembling and reinstalling the filter cartridge, making operation inconvenient. To address these issues, we offer a filtration device for industrial dust collectors. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] This utility model proposes a filtration device for an industrial dust collector. Through the cooperation between the filter element, elastic plates, and springs, the three elastic plates are all locked into the inner wall of the slot, putting the spring in an initial compressed state. Then, the slide rod is pulled to further compress the spring. When the slide rod is released, the spring returns to its original position. The slide rod drives the elastic plates to eject and squeeze the filter element, causing the dust on its outer surface to fall into the collection box. This solves the problem that in existing industrial dust collectors, when cleaning or replacing the dust filter element, the dust and impurities attached to the filter element easily fall into the equipment. At the same time, each cleaning requires disassembly and reinstallation of the filter element, which makes operation inconvenient.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a filtration device for an industrial dust collector, comprising a filter box, a filter element threadedly connected to the inner top wall of the filter box, a slide rod slidably passing through the side of the filter box, a baffle fixedly connected to the outer surface of the slide rod, an elastic plate snapped onto the outer surface of the baffle, and a collection frame snapped onto the inner bottom wall of the filter box.

[0008] A spring is sleeved on the outside of the slide rod, and a circular plate is fixedly connected to the outer surface of the slide rod. One end of the spring is fixedly connected to the outer surface of the circular plate, and the other end of the spring is fixedly connected to the inner side wall of the filter box. A pull rod is fixedly connected to one end of the slide rod.

[0009] Furthermore, a threaded cylinder is fixedly connected to the inner top wall of the filter box, and the outer surface of the threaded cylinder is threadedly connected to the top end of the filter element.

[0010] Furthermore, a slide cylinder is fixedly connected to the side of the filter box, and the inner wall of the slide cylinder is slidably connected to the outer surface of the slide rod.

[0011] Furthermore, the inner wall of the slide cylinder is provided with a guide groove, and the outer surface of the slide rod is slidably connected to the inner wall of the guide groove.

[0012] Furthermore, the outer surface of the baffle is provided with a slot, and the outer surface of the slot is slidably connected to the outer surface of the elastic plate.

[0013] Furthermore, a connecting plate is fixedly connected to the side of the elastic plate, and the connecting plate connects the three elastic plates together. Each elastic plate contacts three filter elements, and one ejection can clean the dust on nine filter elements.

[0014] Furthermore, an installation plate is fixedly connected to the inner bottom wall of the filter box, and the outer surface of the installation plate is slidably connected to the bottom surface of the collection frame.

[0015] (iii) Beneficial effects:

[0016] Compared with existing technologies, the filtration device of this industrial dust collector has the following advantages:

[0017] I. The filtration device of this industrial dust collector, through the cooperation of the filter element, baffle, elastic plate and spring, when it is necessary to clean the dust on the filter cartridge, the three elastic plates are locked into the inner wall of the slot, so that the spring is in the initial compression state. Then the slide rod is pulled to further compress the spring. When the slide rod is released, the spring returns to its original position. The slide rod drives the elastic plate to eject and squeeze the filter element, so that the dust on its outer surface falls into the collection box. This solves the problem that in existing industrial dust collectors, when cleaning or replacing the dust filter element, the dust and impurities attached to the filter element are easy to fall into the equipment, which means that the user has to clean the fallen dust again. At the same time, each cleaning requires the filter element to be disassembled and reinstalled, which makes the operation inconvenient.

[0018] II. The filtration device of this industrial dust collector, through the cooperation between the baffle, the elastic plate and the slot, when the spring is in its natural state, the baffle is in contact with the filter element. At this time, there is no compression. When the elastic plate is installed on the outer surface of the baffle, since the filter element is fixed, the spring will be compressed. When cleaning dust, the compressed spring is compressed again by the slide rod and then released. This will cause the elastic plate to move a distance greater than the filter element. Therefore, at the moment the slide rod is released, the filter element will be ejected and squeezed, which will cause the filter element to vibrate and facilitate the dust to fall off.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] like Figure 1-6 As shown, this utility model provides a technical solution: a filtration device for an industrial dust collector, including a filter box 1, a filter element 2 threadedly connected to the inner top wall of the filter box 1, a threaded cylinder 10 fixedly connected to the inner top wall of the filter box 1, and the outer surface of the threaded cylinder 10 threadedly connected to the top end of the filter element 2. When installing the filter element 2, the top end of the filter element 2 is rotated and screwed onto the outer surface of the threaded cylinder 10 to install the filter element 2.

[0029] A slide rod 3 slides through the side of the filter box 1. A slide cylinder 11 is fixedly connected to the side of the filter box 1. The inner wall of the slide cylinder 11 is slidably connected to the outer surface of the slide rod 3. The slide cylinder 11 can support the slide rod 3 and facilitate the sliding of the slide rod 3. A guide groove 12 is provided on the inner wall of the slide cylinder 11. The outer surface of the slide rod 3 is slidably connected to the inner wall of the guide groove 12. A plate that cooperates with the guide groove 12 is fixedly connected to the outer surface of the slide rod 3. When the slide rod 3 slides, it can prevent it from rotating.

[0030] A baffle 4 is fixedly connected to the outer surface of the slide bar 3. A switch door is provided on one side of the filter box 1. By opening the switch door, the elastic plate 5 can be taken out, and then the filter element 2 can be rotated and unscrewed for easy replacement. The elastic plate 5 is snapped onto the outer surface of the baffle 4. A connecting plate 14 is fixedly connected to the side of the elastic plate 5. The connecting plate 14 connects the three elastic plates 5 together. One elastic plate 5 contacts three filter elements 2. One ejection can clean the dust on nine filter elements 2. The connecting plate 14 installs the three elastic plates 5 together. When installing the elastic plates 5, the three elastic plates 5 can be installed inside the three baffles 4 to improve the installation efficiency.

[0031] The outer surface of the baffle 4 is provided with a slot 13, and the outer surface of the slot 13 is slidably connected to the outer surface of the elastic plate 5. When the elastic plate 5 is installed, a part of it is embedded in the inner wall of the slot 13, which facilitates the installation of the elastic plate 5. The inner bottom wall of the filter box 1 is fitted with a collection frame 6, which can collect the falling dust. The inner bottom wall of the filter box 1 is fixedly connected with an installation plate 15, and the outer surface of the installation plate 15 is slidably connected to the bottom surface of the collection frame 6. A groove matching the installation plate 15 is provided on the bottom surface of the collection frame 6. The installation plate 15 is fitted into the inner wall of the groove, which can install the collection frame 6, making it easy to install and remove the collection frame 6.

[0032] A spring 7 is sleeved on the outside of the slide rod 3. A circular plate 8 is fixedly connected to the outer surface of the slide rod 3. One end of the spring 7 is fixedly connected to the outer surface of the circular plate 8, and the other end of the spring 7 is fixedly connected to the inner side wall of the filter box 1. A pull rod 9 is fixedly connected to one end of the slide rod 3. The pull rod 9 facilitates the pulling of the slide rod 3, thereby facilitating the compression of the spring 7.

[0033] Working principle: When cleaning the dust on the filter element 2, when the spring 7 is in its natural state, its baffle 4 is in contact with the filter element 2. At this time, there is no compression. When the elastic plate 5 is installed on the outer surface of the baffle 4 through the slot 13, since the filter element 2 is fixed, the spring 7 will perform an initial compression. Then, the pull rod 9 pulls the slide rod 3, and the slide rod 3 drives the three elastic plates 5 away from the corresponding filter element 2, and the spring 7 is further compressed. After that, the slide rod 3 is released, the spring 7 returns to its original position, and the slide rod 3 drives the elastic plate 5 through the baffle 4 to eject and squeeze the filter element 2, causing the filter element 2 to vibrate once, and the dust on its outer surface falls into the inside of the collection frame 6. The collection frame 6 can be removed from the inner bottom wall of the filter box 1 through the mounting plate 15 to treat the dust inside the collection frame 6. The filter element 2 can be initially cleaned without disassembling it. If the filter element 2 needs to be disassembled, it can also prevent the dust from falling into the inside of the filter box 1 during the disassembly process.
