Description

Technical Field

[0001] This utility model relates to the technical field of dust removal equipment, and in particular to an electrostatic dust removal dust pretreatment device. Background Technology

[0002] Industrial production processes generate large amounts of smoke containing dust and harmful gases. Direct emission of these gases can pollute the environment and harm human health. Electrostatic precipitators, as an efficient means of smoke treatment, are widely used. However, effective pretreatment of the smoke before electrostatic precipitators is crucial, as it can improve the efficiency and effectiveness of the process and extend the service life of the equipment.

[0003] An existing electrostatic precipitator dust pretreatment device comprises an inlet pipe, a desulfurization chamber, and an outlet. The lower end of the inlet pipe is fixedly connected to the upper end of the dust treatment body by welding. The desulfurization chamber is connected to the raw material storage box on the left side of the dust treatment body via a conveying pipe connected to its left side. Adsorption layers are attached to both sides of the inner wall of the ash collection chamber, and the ash collection chamber is movably connected to the bottom outlet of the ash collection chamber via an external threaded structure on its lower exterior and an internal threaded structure on its upper interior. During the dust removal process, this electrostatic precipitator dust pretreatment device utilizes multiple layers of filtration within the dust treatment body to purify the dust multiple times. While purifying the dust, it also concentrates the dust particles for further processing, making subsequent electrostatic treatment much easier and resulting in better dust treatment.

[0004] However, the filter layer of this device is located on the inner side of the filter chamber. When the filter layer becomes clogged or its adsorption capacity decreases due to prolonged use and needs to be replaced, the equipment must be stopped before operation can begin. This not only leads to production interruption and affects production efficiency, but also increases the company's production costs.

[0005] Therefore, it is necessary to provide an electrostatic dust removal fume pretreatment device to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides an electrostatic dust removal fume pretreatment device, which solves the problem in the prior art that the equipment needs to be stopped when the filter layer is replaced, which affects production efficiency and increases costs.

[0007] To solve the above-mentioned technical problems, this utility model provides an electrostatic dust removal fume pretreatment device, comprising:

[0008] A first filter frame has a partition fixedly installed on its inner side. Two through slots are opened at the top and bottom of the inner side of the first filter frame. An installation slot is opened on one side of each of the four through slots. An elastic element is fixedly installed on the inner side of the installation slot. Sliding grooves are opened on both sides of the inner side of the installation groove. A baffle is slidably connected to the inner side of the sliding groove. A push plate is fixedly installed on one side of the baffle. Two ventilation frames are fixedly installed at the top and bottom of the first filter frame, respectively.

[0009] Two filter components are respectively disposed inside both ends of the first filter frame. Each filter component includes a mounting frame, which is slidably connected to the inside of the end face of the filter component. A filter screen is fixedly installed on the inner side of the mounting frame, and filter cotton is provided on the top of the filter screen. A sealing plate is fixedly installed at one end of the mounting frame.

[0010] The second filter frame is disposed at the bottom of the first filter frame;

[0011] The desulfurization component has a filter assembly fixedly installed at the bottom of the second filter frame, and an exhaust fan is fixedly installed at the output end of the desulfurization component.

[0012] Preferably, the input end of the second filter frame and the output ends of two of the ventilation frames are fixedly installed.

[0013] Preferably, an air inlet pipe is fixedly installed on the top of each of the two ventilation frames, and an air outlet pipe is fixedly installed at the output end of the exhaust fan.

[0014] Preferably, one end of the elastic element and one end of the baffle are fixedly installed.

[0015] Preferably, a handle is fixedly installed on one side of the sealing plate.

[0016] Preferably, rotating plates are rotatably connected to both ends of the first filter frame, and a snap-fit ​​groove is provided at the bottom end of the rotating plate. Snap-fit ​​rods are fixedly installed on both sides of the sealing plate.

[0017] Preferably, a sealing ring is fixedly installed on the other side of the sealing plate.

[0018] Compared with related technologies, the electrostatic dust removal fume pretreatment device provided by this utility model has the following beneficial effects:

[0019] This utility model provides an electrostatic dust removal fume pretreatment device. Through the coordinated structure of a first filter frame, partition, mounting groove, sliding groove, elastic element, baffle, push plate, and two filter components, the device enables online replacement of the filter components. When the filter cotton in one filter component needs to be replaced, pulling the filter component causes the elastic element to push the baffle and push plate. The baffle blocks the through groove, allowing gas to pass through the other filter component, ensuring continuous operation of the equipment. When installing a filter assembly, its insertion pushes the push plate, causing the baffle to move and allowing gas to pass smoothly. This design avoids stopping equipment operation due to filter replacement, effectively reducing the impact on production and lowering enterprise production costs. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] First Embodiment

[0030] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of an electrostatic dust removal fume pretreatment device provided by this utility model; Figure 2 for Figure 1 The diagram shows a partial cross-sectional view of the first filter frame. Figure 3 for Figure 1 The diagram shows the structure of the filter assembly.

[0031] Figure 4 for Figure 3 The diagram shows another perspective of the structure; Figure 5 for Figure 2 The enlarged schematic diagram of part A is shown. An electrostatic dust removal fume pretreatment device includes: a first filter frame 1, a partition 11 fixedly installed on the inner side of the first filter frame 1, two through slots 19 opened at the top and bottom of the inner side of the first filter frame 1, an installation slot 12 opened on one side of each of the four through slots 19, an elastic element 14 fixedly installed on the inner side of the installation slot 12, sliding grooves 13 opened on both sides of the inner side of the installation slot 12, a baffle 15 slidably connected to the inner side of the sliding groove 13, a push plate 16 fixedly installed on one side of the baffle 15, and two ventilation frames 17 fixedly installed at the top and bottom of the first filter frame 1 respectively.

[0032] Two filter components 2 are respectively disposed inside both ends of the first filter frame 1. Each filter component 2 includes a mounting frame 21. The mounting frame 21 is slidably connected to the inside of the end face of the filter component 2. A filter screen 23 is fixedly installed on the inner side of the mounting frame 21. A filter cotton 24 is provided on the top of the filter screen 23. A sealing plate 22 is fixedly installed on one end of the mounting frame 21.

[0033] The second filter frame 3 is disposed at the bottom of the first filter frame 1;

[0034] The desulfurization component 4 is fixedly installed at the bottom of the second filter frame 3, and the output end of the desulfurization component 4 is fixedly installed with an exhaust fan 5.

[0035] The inner side of the second filter frame 3 is provided with a filter plate, which can further filter the smoke and dust in the gas during use, thereby increasing the filtration effect.

[0036] The desulfurization component 4 is equipped with an alkaline absorbent, which can desulfurize the gas when it passes through the desulfurization component 4.

[0037] By setting up the exhaust fan 5, the flow rate of gas inside the first filter frame 1, the second filter frame 3 and the desulfurization component 4 can be accelerated, thereby increasing the efficiency of gas treatment.

[0038] The input end of the second filter frame 3 and the output ends of two of the ventilation frames 17 are fixedly installed.

[0039] An air inlet pipe 18 is fixedly installed on the top of each of the two ventilation frames 17, and an air outlet pipe 51 is fixedly installed at the output end of the exhaust fan 5.

[0040] One end of the elastic element 14 and one end of the baffle 15 are fixedly installed.

[0041] A handle 25 is fixedly installed on one side of the sealing plate 22.

[0042] The handle 25 allows the user to easily move the sealing plate 22 and the mounting frame 21 during use.

[0043] The working principle of the electrostatic dust removal fume pretreatment device provided by this utility model is as follows:

[0044] During use, external smoke and dust gas is diverted through the inlet pipe 18 and enters the inner side of the first filter frame 1 through the two ventilation frames 17 and the through groove 19 installed on the top of the first filter frame 1. After being filtered by the filter cotton 24 inside the two filter components 2, it is transported to the inner side of the second filter frame 3 through the through groove 19 and the ventilation frame 17 at the bottom. Then it is transported to the desulfurization component 4 through the second filter frame 3 for desulfurization. After that, it is discharged into the interior of the exhaust pipe 51 through the exhaust fan 5, and then connected to the electrostatic dust removal device through the exhaust pipe 51.

[0045] When the filter cotton 24 inside the filter assembly 2 needs to be replaced after prolonged use, the user can first pull one of the filter assemblies 2 to move it away from the first filter frame 1. When the filter assembly 2 moves, the elastic element 14 pushes the baffle 15 and causes one side of the push plate 16 to abut against one side of the mounting frame 21, thereby causing the baffle 15 to move synchronously and block the through slots 19 opened at the top and bottom of the first filter frame 1, thus preventing gas from passing through. At this time, the gas will only pass through the interior of the other filter assembly 2.

[0046] When installing filter assembly 2, insert mounting frame 21 into the inner side of first filter frame 1. At this time, one end of mounting frame 21 will push push plate 16, thereby driving baffle 15 to move synchronously and squeezing elastic member 14, so that baffle 15 moves from the inner side of through groove 19 to the inner side of slide groove 13, so that gas can pass through smoothly. At this time, the user can use the same method to replace another filter assembly 2.

[0047] Compared with related technologies, the electrostatic dust removal fume pretreatment device provided by this utility model has the following beneficial effects:

[0048] The first filter frame 1, partition 11, mounting groove 12, sliding groove 13, elastic element 14, baffle 15, push plate 16, and two filter components 2 work together to enable online replacement of the filter components 2 during use. When the filter cotton 24 in one of the filter components 2 needs to be replaced, the filter component 2 is pulled, and the elastic element 14 pushes the baffle 15 and the push plate 16. The baffle 15 blocks the through groove 19, allowing gas to pass through the other filter component 2, ensuring continuous operation of the equipment. When installing the filter assembly 2, its insertion pushes the push plate 16, causing the baffle 15 to move and allowing gas to pass through smoothly. This design avoids stopping the equipment due to filter replacement 24, effectively reducing the impact on production and lowering the company's production costs.

[0049] Second Embodiment

The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0051] Specifically, the difference in the electrostatic dust removal fume pretreatment device provided in the second embodiment of this application is that, in the electrostatic dust removal fume pretreatment device, rotating plates 6 are rotatably connected to both ends of the first filter frame 1, a snap-fit ​​groove 61 is opened at one bottom end of the rotating plate 6, and snap-fit ​​rods 7 are fixedly installed on both sides of the sealing plate 22.

[0052] A sealing ring 8 is fixedly installed on the other side of the sealing plate 22.

[0053] The working principle of the electrostatic dust removal fume pretreatment device provided by this utility model is as follows:

[0054] When in use, the user pushes the sealing plate 22 toward one side of the first filter frame 1 until the side of the sealing ring 8 is in contact with the end face of the first filter frame 1. Then the user rotates the rotating plate 6 so that the snap-fit ​​groove 61 is snapped into the outer side of the snap-fit ​​rod 7, thereby limiting the sealing plate 22.

[0055] Compared with related technologies, the electrostatic dust removal fume pretreatment device provided by this utility model has the following beneficial effects:

[0056] The rotating plate 6, the snap-fit ​​groove 61, the snap-fit ​​rod 7 and the sealing ring 8 work together to make the snap-fit ​​groove 61 snap onto the outer side of the snap-fit ​​rod 7 during use, and make one side of the sealing ring 8 adhere to the end face of the first filter frame 1, thereby increasing the sealing performance between the sealing plate 22 and the first filter frame 1.
