Description

Technical Field

[0001] This application relates to the field of cement production technology, and in particular to a dust collection device for a cement manufacturing production line. Background Technology

[0002] Cement production generates a large amount of dust, which, if directly released into the atmosphere, will cause serious air pollution and affect air quality. Workers exposed to high concentrations of dust for extended periods may develop occupational diseases such as pneumoconiosis. Dust collection devices can significantly reduce dust concentration in the workshop, protecting workers' health. Furthermore, most of the dust generated in cement production consists of incompletely reacted raw materials or semi-finished products, possessing recycling value. The dust collected by the dust collection device can be returned to the production process for reuse, improving raw material utilization and reducing production costs.

[0003] However, some current dust collection devices have difficulty separating cement dust and other dust and impurities floating in the air during collection. When recycling cement dust, the mixing of cement dust with other impurities will affect the quality of the cement. Utility Model Content

[0044] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0046] Please see Figure 1 This application proposes a dust collection device for a cement manufacturing production line, including a first support base 33, a second support base 34, and a first suction component 1 for suctioning waste dust and usable dust, and further including:

[0047] Mounting box 2 is located on first support base 33. The outer wall of mounting box 2 is fixedly connected to first suction component 1. The interior of mounting box 2 is provided with mesh partition 4 so that a first inner cavity and a second inner cavity are formed inside mounting box 2. The first inner cavity is connected to the first suction component 1.

[0048] The recycling bin 23 is fixed with a first support 33 and a second support 34. The recycling bin 23 is equipped with a filter assembly so that multiple recycling chambers 25 are formed inside the recycling bin 23. The recycling chambers 25 are connected to the first inner cavity.

[0049] A cleaning component, located on recycling bin 23, is used to remove waste dust;

[0050] A second suction assembly, disposed on the cleaning assembly, is connected to both the second inner cavity and the cleaning assembly, and is used to suction waste dust into the cleaning assembly; and

[0051] The third suction assembly is located in the recycling bin 23. The third suction assembly is connected to the cleaning assembly and the recycling chamber 25. It is used to suck usable dust from one end of the recycling bin 23 to the other end, so that multiple recycling chambers 25 can recycle usable dust of different particle sizes.

[0052] Waste dust can be fine cement particles generated on cement manufacturing production lines, which are difficult to collect and are more likely to be inhaled, posing a health hazard. Waste dust can also come from environmental dust and metal dust from mechanical wear during cement production. These particles, with sizes close to those of fine cement dust, increase the difficulty and cost of collection, necessitating its removal. Because cement dust contains sticky substances like silicates, it easily clumps together. Usable dust can be large cement agglomerates or individual large particles, which are relatively easy to collect. These agglomerates and large particles have a high cement content and require recycling.

[0053] The first suction assembly 1 may include a fan body, a dust suction head, and an air extraction pipe. The fan body can be fixedly connected to the outer wall of the mounting box 2 via a connecting plate. After the fan body is started, it will suck the dust floating in the air into the air extraction pipe through the dust suction head and enter the mounting box 2.

[0054] Waste dust and usable dust enter the first inner cavity. The mesh partition 4 has multiple mesh holes, allowing waste dust to pass through and enter the second inner cavity, while blocking usable dust in the first inner cavity. Waste dust is then sucked from the first inner cavity to the second inner cavity by the second suction component and further sucked into the cleaning component for removal. Of course, smaller pieces of waste dust will drift to the second inner cavity and be sucked into the cleaning component by the second suction component. The usable dust falls from the first inner cavity into the recycling bin 23 below. The usable dust contains various cement agglomerates of different sizes, as well as larger cement particles of different sizes. Under the suction of the third suction component, the usable dust will move from one end of the recycling bin 23 to the other end. After the usable dust comes into contact with the filter component, the cement agglomerates of different sizes and the larger cement particles will be blocked in their respective recycling chambers 25. This allows for the classification, recycling, and reuse of the usable dust, effectively controlling the particle size distribution of the cement particles after reuse, ensuring the uniformity of the cement particles, and improving the quality of the cement.

[0055] In a preferred embodiment, this application can be further configured such that: the filter assembly includes a plurality of filter plates 36 with filter holes 37, the plurality of filter plates 36 are arranged at intervals toward the direction of approaching the third suction assembly, and the filter plate 36 closer to the third suction assembly in two adjacent filter plates 36 has filter holes 37 with smaller apertures. The apertures of the filter holes 37 of the plurality of filter plates 36 are all different, and the apertures of the filter holes 37 of the filter plates 36 decrease sequentially toward the direction of approaching the third suction assembly. In this way, usable dust of different sizes can be classified and recycled according to size, wherein the filter holes 37 on the filter plate 36 closest to the third suction assembly only allow air to pass through, and do not allow waste dust or dust particles of similar size to waste dust to enter the installation box 2, which facilitates the collection of small cement dust particles, and then the third suction assembly will draw the air into the cleaning box.

[0056] In a preferred embodiment, this application can be further configured such that the cleaning component includes:

[0057] The cleaning box is fixedly connected to the recycling box 23 and is connected to the second suction assembly and the third suction assembly;

[0058] A cleaning shell 18 is movably inserted into the cleaning box 35. The cleaning shell 18 has openings at both ends, and contains multiple activated carbon plates 17 that are vertically aligned and fitted together.

[0059] The exhaust pipe 20 is connected to the cleaning box 35.

[0060] The activated carbon plate 17 is made of activated carbon material. The layers of activated carbon plate 17 can adsorb waste dust in multiple ways, improving the adsorption and removal effect of waste dust entering the cleaning shell 18. The cleaning shell 18 can move horizontally, making it easy to remove the cleaning shell 18 and clean the activated carbon plate 17, or replace it with a new activated carbon plate 17. Finally, the clean air passing through the multiple layers of activated carbon plate 17 will be discharged from the exhaust pipe 20.

[0061] In a preferred embodiment, this application may be further configured as follows: the second suction assembly includes a first exhaust fan 11 and two first air supply pipes 12 disposed on the first exhaust fan 11, the first exhaust fan 11 being disposed on the top of the cleaning box, and the two first air supply pipes 12 being connected to the mounting box 2 and the cleaning box respectively; the third suction assembly includes a second exhaust fan 22 and two second air supply pipes 19 disposed on the second exhaust fan 22, the second exhaust fan 22 being disposed on the recovery box 23, and the two second air supply pipes 19 being connected to the recovery box 23 and the cleaning box respectively.

[0062] After the first exhaust fan 11 starts, it will suck the waste dust from the first air supply pipe 12 into the cleaning box. After the second exhaust fan 22 starts, it will suck the usable dust in the recovery box 23 from one end of the recovery box 23 to the end away from the installation box 2. The filter plate 36 in the recovery box 23 near the second exhaust fan 22 can be set to prevent waste dust or dust particles of similar size from accidentally entering the installation box 2 from passing through, and only allow the drawn-in air to pass through. Then the second exhaust fan 22 will suck this air into the cleaning box to promote the flow speed of waste dust from the second suction component into the cleaning box, so that the waste dust can quickly enter the activated carbon plate 17 below.

[0063] In a preferred embodiment, this application can be further configured such that the dust collection device for a cement manufacturing production line also includes a water spraying assembly, which includes:

[0064] Water tank 9 is fixedly connected to the side wall of cleaning tank. A sealing plug 10 is movably provided inside water tank 9. A push rod is fixedly connected to the sealing plug 10 and the push rod movably passes through water tank 9.

[0065] The water spray box 15 has multiple water spray holes 16 on its surface facing the activated carbon plate 17;

[0066] The connecting pipe 14 is connected at one end to the water tank 9 and at the other end through the side wall of the cleaning tank and connected to the spray box 15.

[0067] Water inlet pipe 13 is connected to water tank 9; and,

[0068] The hydraulic cylinder 7 includes a cylinder body and a hydraulic rod. The cylinder body is fixedly connected to the side wall of the water tank 9. The hydraulic rod is connected to a horizontal plate, which is fixedly connected to the push rod.

[0069] Water is injected into the water tank 9 through the water injection pipe 13. The hydraulic cylinder 7 is activated, and the hydraulic rod causes the push rod to move vertically, thereby causing the sealing plug 10 to push the water in the water tank 9 into the connecting pipe 14, and into the spray box 15. The water is then sprayed from multiple spray holes 16 into the cleaning box to come into contact with the waste dust entering the cleaning box, thereby achieving dust suppression.

[0070] In a preferred embodiment, this application can be further configured such that: a drain pipe 21 is provided at the bottom of the cleaning tank, and the drain pipe 21 is located below the exhaust pipe 20. Wastewater flowing out of the cleaning housing 18 will eventually be discharged through the drain pipe 21. The drain pipe 21 is located at the bottom of the cleaning tank to facilitate the discharge of wastewater, and together with the exhaust pipe 20 above it, it facilitates the separate discharge of clean air and wastewater.

[0071] In a preferred embodiment, this application may be further configured such that: the end of the horizontal plate away from the push rod is connected to a movable rod 3 that extends into the mounting box 2, the portion of the movable rod 3 located between the first suction assembly 1 and the second suction assembly is fixedly connected to the mesh partition 4, and the outer peripheral wall of the mesh partition abuts against the inner peripheral wall of the mounting box 2.

[0072] After the hydraulic cylinder 7 is started, it will move the movable rod 3 in the vertical direction through the horizontal plate, and make the mesh partition 4 move between the first suction assembly 1 and the second suction assembly. During the up and down movement, the mesh partition 4 will scrape off the waste dust and usable dust scattered on the inner wall of the mounting box 2.

[0073] In a preferred embodiment, this application can be further configured such that: the dust collection device for a cement manufacturing production line further includes a discharge assembly, the discharge assembly comprising:

[0074] Multiple discharge pipes 24 are respectively located at the bottom of multiple recycling chambers 25;

[0075] A lead screw 32 is rotatably inserted into the recycling box 23. The lead screw 32 is threadedly connected to multiple filter plates 36, and the filter plates 36 abut against the inner wall of the recycling box 23; and,

[0076] The drive unit is located on the first support base 33 and is connected to the lead screw 32 to make the lead screw 32 rotate.

[0077] When the drive unit operates, the lead screw 32 reciprocates in both directions, causing multiple filter plates 36 to reciprocate horizontally within the recovery box 23. During this movement, the filter plates 36 facilitate the rapid discharge of usable dust from each recovery chamber 25 through their respective discharge pipes 24. A collection box can be placed below the outlet of each discharge pipe 24 to collect the usable dust. The drive unit may include a drive motor 26, which is fixedly connected to the outer wall of the recovery box 23, and the output shaft of the drive motor 26 is fixedly connected to the lead screw 32.

[0078] In a preferred embodiment, this application can be further configured such that: a rotating column 5 is rotatably disposed inside the recycling bin 23, the outer peripheral wall of the rotating column 5 is provided with a plurality of crushing blades, and the driving unit includes:

[0079] The container 29 is fixedly connected to the first support base 33;

[0080] A rotating shaft 28 is rotatably inserted into a receiving box 29, and a first bevel gear 30 is fixedly connected to one end of the rotating shaft 28.

[0081] Motor 26, whose output shaft is fixedly connected to the other end of rotating shaft 28;

[0082] Transmission structure 27, with its two ends connected to rotating shaft 28 and rotating column 5 respectively; and,

[0083] One end of the lead screw 32 is fixedly connected to a second bevel gear 31 and extends into the receiving box 29. The second bevel gear 31 meshes with the first bevel gear 30.

[0084] The motor 26 is started, driving the rotating shaft 28 to rotate. Through the meshing of the first bevel gear 30 and the second bevel gear 31, the lead screw 32 rotates. Simultaneously, the rotation of the rotating shaft 28 causes the transmission structure 27 to rotate the rotating column 5. The rotation of the rotating column 5 causes multiple crushing blades to rotate, thereby pulverizing the agglomerated cement dust that has been sucked in. This ensures that the cement dust entering the recycling bin 23 is of similar size, reducing the types of dust collected and further improving the uniformity of the recycled cement particles, thus improving the quality of the cement. The transmission structure 27 includes a driving pulley, a driven pulley, and a synchronous belt. The driving pulley connects to the rotating shaft 28, the driven pulley connects to the rotating column 5, and the synchronous belt connects the driving pulley and the driven pulley. The rotation of the rotating shaft 28 causes the driving pulley to rotate, which in turn causes the driven pulley and the rotating column 5 to rotate via the synchronous belt.

[0085] Working principle: During use, the first suction component 1 operates, sucking external dust into the first inner cavity of the mounting box 2. Waste dust enters the second inner cavity through the mesh partition 4 and is then sucked into the cleaning box by the second suction component. The hydraulic cylinder 7 activates, causing the push rod 8 and sealing plug 10 to move, thereby spraying clean water from the water tank 9 into the cleaning box through the spray hole 16 to suppress the waste dust. The multi-layer activated carbon plate 17 absorbs the waste dust. Clean air is discharged from the exhaust pipe 20, and wastewater is discharged from the drain pipe 21. Usable dust enters the recycling box 23 from the first inner cavity. The third suction component operates, sucking usable dust from the corresponding mounting box 2 to a location near the third suction component, where multiple filter plates 36 work together to classify and recycle cement dust of different sizes. The motor 26 starts, and the meshing of the first bevel gear 30 and the second bevel gear 31 causes the lead screw 32 to rotate, which in turn causes the filter plate 36 to move in the horizontal direction, allowing the cement dust in each recovery chamber 25 to be discharged. At the same time as the lead screw 32 rotates, the transmission structure 27 causes the rotating column 5 to rotate, which in turn causes multiple crushing blades to rotate, so as to break up the cement dust agglomerates.
