Description

Technical Field

[0001] This application relates to the field of black ash treatment technology, and in particular to an ash-collecting device. Background Technology

[0002] The pyrolysis furnace is a key piece of equipment in the chemical industry. It is used to thermally pyrolyze waste tires at high temperatures to produce carbon black and pyrolysis gas. The ash outlet of the pyrolysis furnace is an important part of the furnace design and is mainly used to discharge the ash and slag generated during the pyrolysis process.

[0003] In related technologies, when pyrolysis furnaces discharge slag, the black ash from each pyrolysis furnace is usually collected and directly loaded onto trucks, which can easily lead to black ash leakage. This causes the black ash to spread throughout the production workshop, thereby polluting the working environment and affecting the health of workers. Utility Model Content

[0004] To facilitate the collection of black ash from the pyrolysis furnace, this application provides an ash-collecting device.

[0005] The dust collection device provided in this application adopts the following technical solution: A dust collection device includes a dust collection pipe with multiple dust collection ports at its upper end. Each dust collection port is equipped with a protective net. A fixing component is provided between the protective net and the dust collection port to fix the protective net to the dust collection port. One end of the dust collection pipe is fixedly connected to and communicates with a bag filter. An induced draft fan is installed at the end of the bag filter away from the dust collection pipe to draw black ash from the dust collection pipe toward the bag filter.

[0006] By adopting the above technical solution, when the slag is discharged from the pyrolysis furnace, the blower can be started to move the black ash self-suction dust pipe to the side of the bag filter. This allows the black ash generated during slag discharge to enter the dust collection pipe through the dust collection port, thereby enabling centralized collection of black ash and reducing the occurrence of black ash spreading throughout the workshop.

[0007] Optionally, the fixing component includes a plurality of fixing bolts, which are threadedly connected to both the protective net and the dust extraction pipe.

[0008] By adopting the above technical solution, the fixing bolt can be rotated to detach it from the dust collection pipe, thereby allowing the protective net to be removed from the dust collection pipe, which facilitates regular cleaning of the inside of the dust collection pipe.

[0009] Optionally, a plurality of collection boxes are placed inside the vacuum pipe, and each collection box corresponds to a vacuum port. Notches are provided on both end faces of the collection box that are perpendicular to the length direction of the vacuum pipe.

[0010] By adopting the above technical solution, the debris falling from the suction port into the suction pipe can be collected by the collection box and concentrated. During cleaning, only the protective net needs to be removed and the collection box needs to be lifted, which facilitates the cleaning of the inside of the suction pipe.

[0011] Optionally, a limiting plate is fixedly connected to the upper end of the bottom surface of the collection box, and the limiting plate is placed at the notch of the collection box.

[0012] By adopting the above technical solution, the position of waste falling into the collection box can be restricted by the limiting plate, reducing the occurrence of waste moving into the dust collection pipe through the gap in the collection box.

[0013] Optionally, a pull ring is fixedly connected to the upper end of the collection box.

[0014] By adopting the above technical solution, the entire collection box can be raised by pulling the upper ring, making it easier to pick up the collection box.

[0015] Optionally, a limiting groove is provided on the bottom surface of the collection box, and a limiting block is fixedly connected inside the dust suction pipe. The limiting block corresponds one-to-one with the limiting groove, and the limiting block is slidably inserted into the limiting groove.

[0016] By adopting the above technical solution, the position of the collection box in the dust collection pipe can be restricted by the limiting block and the limiting groove, thereby making it easier to determine the placement position of the collection box.

[0017] Optionally, a water storage tank is provided at the bottom of the collection box, the water storage tank is filled with water, and a connecting component for connecting the two is provided between the water storage tank and the collection box.

[0018] By adopting the above technical solution, clean water can be added to the water storage tank, and large-diameter dust particles that fall into the collection box can be directly absorbed by the water, thereby reducing the occurrence of dust returning to the air.

[0019] Optionally, the connecting assembly includes a connecting plate fixedly connected to the water storage tank, a connecting bolt threaded onto the connecting plate, and the shank of the connecting bolt threaded onto the bottom surface of the collection tank.

[0020] By adopting the above technical solution, the connecting bolts can be rotated to detach them from the collection tank, thereby allowing the water storage tank to be disassembled from the collection tank, which facilitates the cleaning of the mixture of dust and water inside the water storage tank.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By starting the fan, the black ash self-suction pipe can be moved to one side of the bag filter, so that the black ash generated when the slag is discharged can enter the suction pipe from the suction port, thereby collecting the black ash in a concentrated manner and reducing the occurrence of black ash spreading in the workshop. 2. The collection box can collect debris that falls into the vacuum pipe from the suction port and concentrate the debris. When cleaning, simply remove the protective net and lift the collection box, which makes it easy to clean the inside of the vacuum pipe. 3. The position of waste falling into the collection box can be restricted by the limiting plate, reducing the occurrence of waste moving into the dust collection pipe through the opening of the collection box.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0025] Example 1 A dust-collecting device, as shown in the figure Figure 1 It includes a dust extraction pipe 1, which is buried inside the ground of the factory area. The dust extraction pipe 1 is rectangular in shape, and multiple dust extraction ports 11 are opened at the upper end of the dust extraction pipe 1. Each dust extraction port 11 corresponds to the discharge port of the pyrolysis furnace above the dust extraction pipe 1.

[0026] Each suction port 11 is equipped with a protective net 2, and a fixing component 3 is provided between the protective net 2 and the suction port 11 to fix the protective net 2 to the suction port 11. The fixing component 3 includes multiple fixing bolts 31. In this embodiment, four fixing bolts 31 are provided, and the four fixing bolts 31 are respectively located at the four corners of the protective net 2. The fixing bolts 31 are threadedly connected to the protective net 2, and the shank of the fixing bolts 31 is threadedly connected to the suction pipe 1.

[0027] Therefore, by rotating the fixing bolt 31, the fixing bolt 31 can be disengaged from the dust suction pipe 1, and the protective net 2 can be removed from the dust suction pipe 1.

[0028] A bag filter 4 is fixedly connected to and communicates with one end of the dust collection pipe 1. The bag filter 4 is a bag dust collection device in the prior art. An induced draft fan 5 is installed at the end of the bag filter 4 away from the dust collection pipe 1 to pull black ash from the dust collection pipe 1 to one side of the bag filter 4.

[0029] Reference Figure 1 , Figure 2 and Figure 3 Multiple collection boxes 6 are placed inside the vacuum pipe 1. Each collection box 6 is a cuboid with an opening at the top. A pull ring 64 is fixedly connected to the opening at the top of the collection box 6. Each collection box 6 corresponds to a vacuum port 11. Each collection box 6 has a notch 62 for collecting black ash on its two end faces perpendicular to the length direction of the vacuum pipe 1.

[0030] Thus, non-floating particles or debris falling from the protective net 2 can directly fall into the collection box 6. At the same time, in order to limit the position of non-floating particles or debris in the collection box 6, a limiting plate 63 is fixedly connected to the upper end of the bottom surface of the collection box 6. The limiting plate 63 is placed at the gap 62 of the collection box 6 and the lower part of the gap 62 is sealed.

[0031] To facilitate determining the placement of the collection box 6, a limiting groove 61 is provided on the bottom surface of the collection box 6, and a limiting block 7 is fixedly connected inside the dust suction pipe 1. The limiting block 7 corresponds one-to-one with the limiting groove 61, and the limiting block 7 is slidably inserted into the limiting groove 61.

[0032] The implementation principle of Example 1 is as follows: When slag is discharged from the pyrolysis furnace, the induced draft fan 5 is started, and the generated black ash enters the dust collection pipe 1 from the dust suction port 11. The induced draft fan 5 drives the black ash from the dust suction pipe 1 towards the bag filter 4, thereby collecting the black ash in a concentrated manner. At the same time, some non-floating objects can fall into the collection box 6 through the protective net 2 for centralized collection.

[0033] Example 2 The difference from Example 1 is that: (Refer to...) Figure 4 and Figure 5The bottom of the collection tank 6 is provided with a water storage tank 8, which is a cuboid shape with an open top and is filled with water. A connecting component 9 is provided between the water storage tank 8 and the collection tank 6 to connect the two.

[0034] The connecting assembly 9 includes two connecting plates 92 fixedly connected to the water storage tank 8, located on opposite sides of the water storage tank 8. Connecting bolts 91 are threaded onto the connecting plates 92, with the shanks of the connecting bolts 91 threaded onto the bottom surface of the collection tank 6.

[0035] The implementation principle of Example 2 is as follows: clean water can be added to the water storage tank 8, and large-diameter dust particles that fall into the collection tank 6 can be directly absorbed by the water. When it is necessary to clean the water storage tank 8 on the collection tank 6, the connecting bolt 91 can be rotated to disengage it from the collection tank 6, thereby allowing the water storage tank 8 to be removed from the collection tank 6.

[0036] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
