Description

Technical Field

[0001] The invention relates to the field of calcium carbide crushing and conveying, and in particular to an auxiliary dust collecting device in a calcium carbide processing, crushing and conveying area. Background Art

[0002] With the rapid development of the economy, the production scale of various chemical companies is expanding year by year, and the demand for calcium carbide raw materials by polyvinyl chloride and BDO manufacturers is also increasing year by year.

[0003] When processing calcium carbide raw materials, it is inevitable to crush them, and dust will be generated during the crushing process. Therefore, a ventilation system is generally set up in the crushing area. This type of ventilation system can suck the dust and powder in the crushing and conveying area into the ventilation system, and then a dust collecting device can be set up at the end of the ventilation system. In order to avoid the waste of raw material calcium carbide, the calcium carbide dust will be uniformly recovered and processed at the end of the dust collecting device. In this way, the dust generated by the crushing will pass through the ventilation duct and stay inside the ventilation duct. Therefore, the ventilation duct must be cleaned later. At the same time, the internal ventilation system is often a certain distance away from the crushing area, so the dust collection effect is also very limited.

DETAILED DESCRIPTION

[0045] Below, the invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0046] Example 1: Please refer to Figure 1-2 According to an embodiment of the present invention, an auxiliary dust collection device for the crushing and conveying area of ​​calcium carbide processing includes a dust collecting mechanism 1 arranged above the crushing and conveying area, the top of the dust collecting mechanism 1 is connected with a connecting pipe 2, and the end of the connecting pipe 2 away from the dust collecting mechanism 1 is connected with a three-way pipe 3, the dust collecting mechanism 1 is provided with two, and the end of the three-way pipe 3 away from the dust collecting mechanism 1 is connected to the dust exhaust pipe. The dust collecting mechanism 1 can collect the dust generated by the calcium carbide processing in the crushing and conveying area. After being absorbed by the dust collecting mechanism 1, it can be centrally processed and collected in the subsequent process. The collected calcium carbide dust can be recycled to save the loss of calcium carbide raw materials.

[0047] In order to enable the dust collecting mechanism 1 to collect the calcium carbide dust generated during the crushing and conveying process, in this embodiment, the dust collecting mechanism 1 includes a dust collecting box 4, a dust collecting hood 5 is fixedly installed at the bottom of the dust collecting box 4, and a top cover 6 is fixedly installed at the top end of the dust collecting box 4. The interior of the dust collecting box 4 is connected to the interior of the dust collecting hood 5 and the interior of the top cover 6. A connecting hole 7 is opened at the top center of the top cover 6, and one end of the connecting pipe 2 away from the three-way pipe 3 is fixedly installed in the connecting hole 7. The dust collecting hood 5 is arranged above the crushing and conveying area. Because the three-way pipe 3 is connected to the dust exhaust pipe, when the dust exhaust pipe is exhausted, the top cover 6 can be sucked through the connecting pipe 2 at the same time, and then the dust collecting operation of the dust collecting hood 5 above the crushing and conveying area is realized.

[0048] See also Figure 3-8 In order to enable the dust collection box 4 to absorb the calcium carbide dust absorbed by the dust hood 5 to a certain extent, and then facilitate subsequent direct collection, in this embodiment, a dust collection assembly 8 is provided inside the dust collection box 4, and the dust collection assembly 8 includes a cross bar 14 arranged along the width direction of the dust collection box 4, and both ends of the cross bar 14 penetrate the side walls of the dust collection box 4, and the cross bar 14 is located inside the dust collection box 4 and fixedly installed with a dust collection cylinder 15, and a dust collection bag (not shown in the figure) is installed inside the dust collection cylinder 15. In this way, when the calcium carbide dust enters the dust collection box 4 from the dust collection hood 5, it can pass through the inside of the dust collection cylinder 15 and then be absorbed by the dust collection bag inside the dust collection cylinder 15. In order to enable the dust inside the dust collection cylinder 15 to be conveniently collected later, the dust collection box 4 is provided with an assembly hole 12 on the top of the side wall arranged along its length direction, and an assembly sleeve 13 arranged opposite to the assembly hole 12 is fixedly installed on the outer wall of the dust collection box 4, and the end of the cross bar 14 penetrates the assembly sleeve 13. When it is necessary to collect the calcium carbide dust inside the dust collection tube 15 in the future, the cross bar 14 can be given a reciprocating motion along its axial direction, so that the dust collection tube 15 can be shaken back and forth. At this time, the shaken calcium carbide dust can be collected under the dust collection box 4. Such a design can avoid the accumulation of calcium carbide dust inside the subsequent dust exhaust pipe, reduce the frequency of cleaning the inside of the dust exhaust pipe, and save the loss of calcium carbide raw materials.

[0049] In order to allow the battery dust entering the dust box 4 from the dust cover 5 to pass through the dust cylinder 15 as much as possible, in this embodiment, the dust box 4 is fixedly installed with inclined plates 9 at the bottom of the two inner side walls arranged along the width direction thereof, and the bottom of the dust box 4 is also fixedly installed with angle plates 10 between two adjacent assembly holes 12, and the inclined plates 9 and the angle plates 10 are arranged along the length direction of the cross bar 14, and the bottom opening of the dust cylinder 15 is directly opposite to the two adjacent angle plates 10 or / and between the angle plates 10 and the inclined plates 9, and the inclined plates 9 are arranged obliquely downward along the side walls in the width direction of the dust box 4, and the top angle of the angle plates 10 is arranged toward the center of the dust box 4. The mutual assembly between the inclined plates 9 and the angle plates 10 can make the airflow at the bottom of the dust box 4 only pass between the inclined plates 9 and the angle plates 10 or between the angle plates 10 and the angle plates 10, and the area between the angle plates 10 and the angle plates 10 and / or the inclined plates 9 will inevitably be provided with the dust cylinder 15, so the dust collection efficiency of the dust cylinder 15 can be greatly increased. In order to ensure the stability of the dust collection cylinder 15 when it is subsequently discharged, the dust collection box 4 is fixedly installed with a first slide rail 11 on the top of the inner side wall along the width direction thereof. The first slide rail 11 is arranged along the width direction of the dust collection box 4. The dust collection box 4 is also provided with a connecting strip 16 arranged along its length direction. The connecting strip 16 is arranged between two adjacent dust collection cylinders 15, and the two ends of the connecting strip 16 are fixedly installed with a slide seat 22. The slide seat 22 is slidably installed on the first slide rail 11. A locking hoop 21 is installed on the top of the connecting strip 16. The cross bar 14 is fixedly installed on the connecting strip 16 through the locking hoop 21. When the cross bar 14 is reciprocated along its axial direction by external force, the synchronous movement between all the cross bars 14 can be achieved with the help of the connecting strip 16. Moreover, because the two ends of the connecting strip 16 can also slide with the first slide rail 11 on the inner side wall of the dust collection box 4 through the slide seat 22, the stability of the dust collection cylinder 15 when it is shaken is also improved to a certain extent.

[0050] The calcium carbide dust entering the dust box 4 is bound to accumulate on the top of the angle plate 10 and the inclined plate 9. In order to enable the battery dust accumulated on the top of the angle plate 10 and the inclined plate 9 to be self-cleaned later, in this embodiment, a clamp 17 is fixedly installed on the outer side of the bottom of the dust collection tube 15, and an extension block 18 is fixedly installed on the side of the clamp 17 facing the angle plate 10 and / or the inclined plate 9. A hanging rod 19 is fixedly installed on the bottom of the end of the extension block 18 away from the clamp 17, and a cleaning brush 20 is fixedly installed on the bottom end of the hanging rod 19, and the bottom of the cleaning brush 20 is set tightly against the inclined plate 9 and / or the angle plate 10. When the dust collection tube 15 shakes, it can drive the clamp 17 to shake synchronously, and then the clamp 17 drives the cleaning brush 20 to clean the top of the inclined plate 9 and the angle plate 10 through the extension block 18 and the hanging rod 19.

[0051] Through the above-mentioned scheme of the present invention, the inside of the dust collection box 4 provided in the present invention can collect the calcium carbide dust generated in the crushing and conveying area, and does not require external energy. Dust collection can be achieved by only the fan required by the internal dust exhaust pipe. When the calcium carbide dust enters the inside of the dust collection box 4, it can be blocked by the inclined plate 9 and the angle plate 10, so that the airflow can pass through the inside of the dust collection tube 15 as much as possible. The dust collection tube 15 can also be shaken by the cross bar 14 in the subsequent process, so that the dust inside the dust collection tube 15 can be shaken out, so as to collect it, which can reduce the accumulation of calcium carbide dust in the subsequent dust exhaust pipe, and can also reduce the frequency of cleaning the inside of the dust exhaust pipe, while also saving the loss of calcium carbide raw materials.

By pushing or pulling the slider 25 with external force, the slider 25 can drive the vertical strips 26 to move synchronously through the extension rod 251, and the vertical strips 26 can drive the connecting shaft 28 to move synchronously through the push-pull plate 27, so that the connecting shaft 28 can be used to reciprocate the cross bar 14.

[0053] In order to enable the slider 25 to reciprocate in the second slide rail 24, in this embodiment, a first bearing seat 29 is fixedly installed on the top of the top cover 6, and the first bearing seat 29 is arranged opposite to the support frame 23. A vertical shaft 30 is rotatably installed inside the first bearing seat 29, and a turntable 31 is fixedly installed on the top end of the vertical shaft 30. A first fixed shaft 32 is fixedly installed on the top of the turntable 31 near the side, and a crank 33 is rotatably installed on the top of the first fixed shaft 32. A second fixed shaft 34 is fixedly installed on the top end of the slider 25, and one end of the crank 33 away from the first fixed shaft 32 is rotatably connected to the second fixed shaft 34. When the vertical shaft 30 is driven to rotate, the vertical shaft 30 can drive the turntable 31 to rotate synchronously, and the rotation of the turntable 31 can drive the crank 33 to move through the first fixed shaft 32, and the crank 33 drives the slider 25 to move through the second fixed shaft 34, so that the slider 25 can reciprocate in the second slide rail 24.

[0054] In order to enable the two vertical shafts 30 to be driven synchronously, in this embodiment, an assembly frame 36 is fixedly installed on the top of the top cover 6, and the assembly frame 36 is arranged between the two vertical shafts 30. A motor 37 is fixedly installed on the top of the assembly frame 36. A driving pulley 38 is fixedly installed on the output shaft of the motor 37. A driven pulley 35 is fixedly installed on the vertical shaft 30. There are two driving pulleys 38. The driving pulleys 38 are respectively connected to the driven pulleys 35 on both sides through a transmission belt 39. The output shaft end of the motor 37 is also connected to the top of the top cover 6 through the first bearing seat 29. When the motor 37 is started, the motor 37 can drive the driving pulley 38 to rotate, and the driving pulley 38 then drives the driven pulley 35 to rotate through the transmission belt 39. The driven pulley 35 can drive the vertical shaft 30 to rotate, and then the rotation adjustment of the turntable 31 is realized.

[0055] Through the above-mentioned scheme of the present invention, the turntable 31 provided in the present invention can adjust the slider 25, so that the slider 25 can realize reciprocating movement in the second slide rail 24, and then the slider 25 drives the push-pull plate 27 to push and pull reciprocatingly through the extension rod 251 and the vertical bar 26, and the push-pull plate 27 drives the cross bar 14 to move back and forth in the dust box 4 through the connecting shaft 28, thereby shaking the dust cylinder 15 and shaking off the calcium carbide dust adsorbed in the dust cylinder 15.

[0065] The dust box 4 provided in the present invention can collect the calcium carbide dust generated in the crushing and conveying area, and does not require external energy. Dust collection can be achieved only by the fan required by the internal dust exhaust pipe. When the calcium carbide dust enters the dust box 4, it can be blocked by the inclined plate 9 and the angle plate 10, so that the airflow can pass through the dust cylinder 15 as much as possible. The dust cylinder 15 can also be shaken by the cross bar 14 in the subsequent process, so that the dust inside the dust cylinder 15 can be shaken out, so as to collect it. The accumulation of calcium carbide dust in the subsequent dust exhaust pipe can be reduced, and the frequency of cleaning the inside of the dust exhaust pipe can also be reduced. At the same time, the loss of calcium carbide raw materials can be saved.

[0066] The turntable 31 provided in the present invention can adjust the slider 25 so that the slider 25 can move back and forth in the second slide rail 24, and then the slider 25 drives the push-pull plate 27 to push and pull back and forth through the extension rod 251 and the vertical strip plate 26. The push-pull plate 27 then drives the cross bar 14 to move back and forth in the dust box 4 through the connecting shaft 28, thereby shaking the dust cylinder 15 and shaking off the calcium carbide dust adsorbed in the dust cylinder 15.

[0067] The baffle 41 provided in the present invention can be flipped and adjusted between the two outer protective plates 40. When the baffle 41 is away from the bottom center area of ​​the dust hood 5, it can be covered above the crushing and conveying area. When the baffle 41 is close to the bottom center area of ​​the dust hood 5, the outlet of the discharged calcium carbide dust can be concentrated and narrowed when the dust cylinder 15 inside the subsequent dust box 4 discharges dust, which is convenient for collection. At the same time, the sealing plate 47 provided inside the dust hood 5 can be flipped and adjusted around the rotating shaft 46, and can be opened when the dust hood 5 is working, and the dust hood 5 can be sealed when the dust hood 5 is not working.

[0068] An adjusting rod 66 is installed inside the three-way pipe 3 provided in the present invention, and the plugs 67 at both ends of the adjusting rod 66 are arranged opposite to the connecting sleeves 61 on both sides. By rotating the handle 63, the plug 67 can be selected to seal the connecting sleeve 61 at one end. When a different crushing and conveying area is selected later, the dust collecting mechanism 1 on the other side can be in a shutdown state and its interior will not be affected by dust.
