[0002] Calcium oxide is usually a white or grayish blocky or granular solid. In industrial production, blocky calcium oxide needs to be crushed to meet the particle size requirements of different applications.

[0003] The crushing of calcium oxide requires the use of a crusher to impact or crush it. After the calcium oxide lumps are fed into the crusher, the crushing process generates a large amount of dust. This dust needs to be treated by a filtration and collection device, otherwise it will spread freely and affect the surrounding environment and air. In existing filtration and collection devices, all the dust is filtered by the filtration mechanism, which is easily clogged by the accumulation of dust and needs to be cleaned frequently.

[0004] Therefore, this utility model provides a dust collection hood for filtering calcium oxide crushed powder. Utility Model Content

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 5As shown, the calcium oxide crushing dust filter dust collection hood of this utility model embodiment includes a cover 1; multiple curtains 12 are fixedly connected to the bottom edge of the cover 1; a connector 13 is fixedly connected to the middle of the cover 1; an air duct 14 is fixedly connected to the top of the cover 1; the air duct 14 communicates with the interior of the cover 1; a filter fan 15 is installed in the middle of the air duct 14; a collection box 16 is detachably installed in the middle of the air duct 14; a limit pin 17 is slidably installed on the side wall of the air duct 14; a handle 18 is fixedly connected to the side wall of the collection box 16; some water is injected into the inside of the collection box 16, and then... The collection box 16 is installed into the air duct 14, and the position of the collection box 16 is restricted by inserting the limiting pin 17 into the insertion hole in the middle of the collection box 16. The lifting mechanism is used to lift the cover 1 through the connecting piece 13, and the cover 1 is moved to the calcium oxide crushing device. Multiple curtains 12 block some of the dust and flying debris generated by crushing. The filter fan 15 is started to draw air. Some of the dust below the cover 1 will be drawn into the air duct 14 with the air. When the dust passes through the curved section of the air duct 14 with the airflow, some of it will be guided towards... As the airflow blows across the surface of the liquid in the collection box 16, some dust particles will fall onto the liquid and become wetted, making them less likely to be re-electrified. The remaining dust particles will continue to move along the duct 14 and enter the filter fan 15, where they will be filtered and collected by the filter element. Because some dust falls into the liquid in the collection box 16, the amount of dust entering the filter fan 15 and being blocked by the filter element is reduced. Therefore, under otherwise unchanged conditions, it will take longer for the filter element in the filter fan 15 to accumulate to a certain level. This reduces the frequency of cleaning the filter fan 15. When cleaning is required, the limit pin 17 can be slid to separate the limit pin 17 from the collection box 16, and then the handle 18 can be pulled to remove the collection box 16 from the air duct 14. The wastewater containing dust in the collection box 16 can be cleaned and replaced. Through the above structure, when filtering calcium oxide crushed dust, some dust can be wetted and collected by water, reducing the amount of dust flying towards the filter mechanism with the airflow, thereby reducing the workload of the filter mechanism and reducing the frequency of cleaning the filter mechanism.

[0026] like Figures 1 to 4As shown, a collection frame 2 is detachably installed in the middle of the air duct 14; the collection frame 2 is located above the collection box 16; multiple cotton cloths 21 are fixed inside the collection frame 2; multiple cotton ropes 22 are fixed to the bottom of the cotton cloths 21; a weight 23 is fixed to the middle of the cotton ropes 22 near the bottom; during operation, the collection frame 2 is inserted into the air duct 14, and the handle 18 is limited by inserting the limiting pin 17 into the socket in the middle of the handle 18. The bottom end of the cotton rope 22 inside the air duct 14 will fall under the gravity of the weight 23 and extend into the water in the collection box 16. Subsequently, some of the water will be absorbed by the cotton rope 22 and gradually the cotton rope 22 and cotton cloth will be removed from bottom to top. 21 is moistened. When dust flows with the airflow inside the duct 14, some dust will be adsorbed by the moistened cotton cloth 21 as it passes over the surface of the cotton cloth 21, thus remaining on the surface of the cotton cloth 21 and difficult to leave. This further reduces the amount of dust entering the filter fan 15. After a period of time, the collection frame 2 can be removed from the duct 14 to clean the impurities attached to the surface of the cotton cloth 21. Through the above structure, the moistened cotton cloth 21 can be used to adsorb some of the dust flowing inside the duct 14, further reducing the amount of dust flying to the filter mechanism, further reducing the workload of the filter mechanism, and reducing the cleaning frequency of the filter mechanism.

[0027] like Figures 1 to 6 As shown, a plurality of closed plates 3 are rotatably connected to the middle of the collection box 16; an operating rod 31 is rotatably connected to the middle of the collection box 16; the operating rod 31 is fixedly connected to the top end of one of the closed plates 3; a connecting rod 32 is fixedly connected to the bottom end of the plurality of closed plates 3; when the collection box 16 is filled with water, it is inserted into the air duct 14. During this process, if the collection box 16 accelerates or decelerates, the water inside the collection box 16 may slosh, potentially causing a large amount of water to overflow and flow into the air duct 14. To reduce water spillage during shaking, before inserting the collection box 16 into the duct 14, the operating lever 31 can be rotated to rotate a sealing plate 3. Then, multiple sealing plates 3 can be rotated synchronously via the connecting rod 32. Once in position, the multiple sealing plates 3 will join together to block the water below, making it difficult for the shaking water to spill out. With the above structure, when the collection box 16 containing water is inserted into the duct 14, the occurrence of water shaking and overflowing into the duct 14 can be reduced.

[0028] like Figures 1 to 4As shown, a movable frame 4 is slidably connected to the middle of the collection frame 2; multiple pairs of cleaning scrapers 41 are fixed to the bottom of the movable frame 4; each pair of cleaning scrapers 41 is respectively set on both sides of the cotton cloth 21; during operation, after a period of use, a thick layer of dust will adhere to the surface of the cotton cloth 21, which will reduce the subsequent dust adhesion effect. At this time, the movable frame 4 can be slid to move the multiple pairs of cleaning scrapers 41. Through the movement of the multiple pairs of cleaning scrapers 41, the wet dust and some water adhering to the surface of the cotton cloth 21 are scraped off and fall under the action of gravity. The fallen wet dust will fall into the collection box 16. After the cleaned cotton cloth 21 absorbs water again, the dust adhesion effect will increase accordingly. Through the above structure, some of the wet dust accumulated on the surface of the cotton cloth 21 can be scraped off during the operation of the device, so that the dust adhesion effect of the cotton cloth 21 can be partially restored.

[0029] like Figures 1 to 6 As shown, the handle 18 is a transparent hollow tube; the handle 18 is connected to the inside of the collection box 16; an overflow pipe 5 is fixed to the middle of the handle 18; the other end of the overflow pipe 5 is connected to the inside of the collection box 16; during operation, some water in the collection box 16 will enter the handle 18, and the air inside the handle 18 will be discharged through the overflow pipe 5, so that the water level in the handle 18 is consistent with the water level in the collection box 16, so as to facilitate the observation of the amount of water in the collection box 16. As the device runs for a long time, some water molecules will be discharged with the airflow, and the liquid level will gradually drop. When the liquid level is too low, the cotton rope 22 will have difficulty contacting the water. At this time, the water level in the handle 18 can be observed to determine whether water needs to be added. Through the above structure, the remaining water in the collection box 16 can be easily judged so as to replenish the water in the collection box 16 in a timely manner and reduce the occurrence of the cotton cloth 21 not being fully wetted.

[0030] like Figures 1 to 6 As shown, a water injection pipe 6 is fixedly connected to the middle of the handle 18; the top of the water injection pipe 6 is rotatably connected to a cover plate 61 via a torsion spring; during operation, when it is necessary to inject water into the collection box 16, the cover plate 61 can be rotated to open the water injection pipe 6, and then water can be injected into the handle 18 through the water injection pipe 6. The water will enter the collection box 16 through the handle 18, thereby completing water replenishment during the operation of the device without having to remove the collection box 16. With the above structure, water can be conveniently replenished into the collection box 16 without having to remove the collection box 16 from the air duct 14, improving the ease of use of the device.

[0031] like Figure 6As shown, a sealing strip 7 is fixed to the side wall of the sealing plate 3; the sealing strip 7 is made of rubber material; during operation, when multiple sealing plates 3 are rotated and spliced ​​together, multiple sealing strips 7 will seal the gaps between multiple sealing plates 3, thereby reducing the occurrence of water overflowing from the gaps between multiple sealing plates 3.

[0032] During operation, some water is injected into the collection box 16, and then the collection box 16 is installed into the air duct 14. The position of the collection box 16 is restricted by inserting the limiting pin 17 into the insertion hole in the middle of the collection box 16. The lifting mechanism is used to lift the cover 1 through the connecting piece 13 and move the cover 1 onto the calcium oxide crushing device. Multiple curtains 12 block some of the dust and flying debris generated during crushing. The filter fan 15 is started to draw air in. Some of the dust below the cover 1 is drawn into the air duct 14 with the airflow. When the dust passes through the bend of the air duct 14 with the airflow, some of it is guided and blown towards the surface of the water in the collection box 16. At this time, some of the dust falls onto the water with the airflow and is soaked by the water, making it difficult to continue. As the dust continues to rise, another portion of the dust will move along the duct 14 with the air and enter the filter fan 15, where it will be filtered and collected by the filter element inside the filter fan 15. Since some dust falls into the water in the collection box 16, the amount of dust entering the filter fan 15 and being blocked by the filter element will be reduced accordingly. Therefore, under otherwise unchanged conditions, it will take longer for the filter element inside the filter fan 15 to accumulate to a certain extent, thus reducing the frequency of cleaning the filter fan 15. When cleaning is required, the limiting pin 17 can be slid to separate it from the collection box 16, and then the handle 18 can be pulled to remove the collection box 16 from the duct 14. The wastewater containing dust in the collection box 16 can then be cleaned and replaced. The collection frame 2 can then be inserted into the duct 14. Inside the air duct 14, the handle 18 is limited by a limiting pin 17 inserted into the hole in the middle of the handle 18. The bottom end of the cotton rope 22, which enters the air duct 14, will fall under the gravity of the weight block 23 and extend into the water in the collection box 16. Subsequently, some of the water will be absorbed by the cotton rope 22 and gradually wet the cotton rope 22 and cotton cloth 21 from bottom to top. When the dust flows with the airflow inside the air duct 14, some of the dust will be absorbed by the wet cotton cloth 21 when it passes over the surface of the cotton cloth 21, thus remaining on the surface of the cotton cloth 21 and being difficult to remove, thereby further reducing the amount of dust entering the filter fan 15. After a period of time, the collection box 2 can be removed from the air duct 14 to clean the impurities attached to the surface of the cotton cloth 21. When the collection box 16 is filled with water, When the collection box 16 is inserted into the air duct 14, if the collection box 16 accelerates or decelerates during this process, the water inside the collection box 16 may slosh around, potentially causing a large amount of water to overflow and flow into the air duct 14. To reduce water overflow during sloshing, before inserting the collection box 16 into the air duct 14, the operating lever 31 can be rotated to rotate a sealing plate 3. Then, multiple sealing plates 3 can be rotated synchronously via the connecting rod 32. Once in position, the multiple sealing plates 3 will interlock, blocking the water below and preventing the sloshing water from overflowing. After a period of use, a thick layer of dust will adhere to the surface of the cotton cloth 21, reducing the effectiveness of subsequent dust adhesion. At this point, the sliding frame 4 can be slid to move multiple pairs of cleaning scrapers 41.The movement of multiple pairs of cleaning scrapers 41 scrapes away the wet dust and some water adhering to the surface of the cotton cloth 21, which then falls under gravity. The fallen wet dust falls into the collection box 16. After the cleaned cotton cloth 21 absorbs water again, its adhesion to dust will increase accordingly. Some of the water in the collection box 16 will enter the handle 18, while the air inside the handle 18 will be discharged through the overflow pipe 5, thus making the water level in the handle 18 consistent with the water level in the collection box 16, so as to facilitate the observation of the amount of water in the collection box 16. As the device operates for a long time, some water molecules will be discharged with the airflow, and the liquid level will gradually drop. When the water level is too low, the cotton rope 22 may have difficulty contacting the liquid. In this case, the water level in the handle 18 can be observed to determine if water needs to be added. When water needs to be added to the collection box 16, the cover 61 can be rotated to open the water inlet pipe 6, and then water can be injected into the handle 18 through the water inlet pipe 6. The water will then enter the collection box 16 through the handle 18, thus replenishing the water during device operation without needing to remove the collection box 16. When multiple sealing plates 3 are rotated and joined together, multiple sealing strips 7 will seal the gaps between the sealing plates 3, thereby reducing the possibility of water overflowing from these gaps.
