Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust removal equipment for calcium hydroxide processing and crushing. Background Technology

[0002] Dust collection equipment is used to remove dust generated during the crushing and processing of calcium hydroxide. The equipment consists of a dust collection box, inlet, filter bags, discharge pipe, fan, air inlet, and air inlet pipe. During the pretreatment and filtration stage: dust-laden gas enters through the inlet of the dust collection box. Large dust particles settle directly into the ash hopper due to gravity, while fine dust rises with the airflow to the filter bag area and is intercepted by the filter bag fiber layer. The purified gas passes through the filter bags into the clean air chamber and is discharged through the discharge pipe and fan. The dust removal trigger condition is when dust accumulation on the filter bag surface causes the equipment resistance to rise to a set value, and the pressure difference... The sensor sends a signal to the PLC to start the dust removal program. During the pulse jet cleaning stage: the clean air outlet valve of the current filter bag chamber is closed, the filtration airflow is stopped, the electromagnetic pulse valve opens instantly, and compressed air enters the jet pipe through the air inlet and air inlet pipe and is injected into the filter bag. The high-pressure airflow induces 5-7 times the amount of secondary air to enter the filter bag, causing the filter bag to expand and shake rapidly. The attached dust falls off into the ash hopper under the action of reverse airflow and mechanical vibration. During the filtration recovery stage: after the dust removal is completed, the clean air outlet valve is reopened, the filter bag chamber resumes filtration, and the dust in the ash hopper is discharged through the ash discharge valve at regular intervals.

[0003] In their daily work, the inventors discovered that when the dust removal equipment is in use, although the compressed air sprayed from the blowpipe into the filter bag can cause the filter bag to expand and shake rapidly, thus removing the dust from the inner wall of the filter bag, it cannot effectively shake off the dust attached to the outer wall of the filter bag. This is especially true when the filter bag is large, resulting in incomplete dust removal from the filter bag. Utility Model Content

[0004] The purpose of this invention is to solve the problem that, in actual use, although the compressed air ejected from the blowpipe and injected into the filter bag can cause the filter bag to expand and shake rapidly, thus removing the dust from the inner wall of the filter bag, it cannot effectively shake off the dust attached to the outer wall of the filter bag, especially when the filter bag is large, resulting in incomplete dust removal. Therefore, this invention proposes a calcium hydroxide processing and crushing dust removal device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a calcium hydroxide processing and pulverizing dust removal device, comprising a dust collection box, wherein an air inlet pipe and an air inlet are fixedly connected to the right end of the dust collection box, an exhaust pipe is fixedly connected to the upper end of the dust collection box, a fan is installed at the other end of the exhaust pipe, an air inlet is fixedly connected to the right end of the air inlet pipe, a filter bag is provided on the inner wall of the dust collection box, a cleaning component is provided on the arc surface of the filter bag, a blowpipe is fixedly connected to the inner wall of the dust collection box, the blowpipe is connected to the air inlet pipe, and the cleaning component includes a rotating rod provided on the arc surface of the filter bag, and a brush is fixedly connected to one side of the rotating rod.

[0006] The effect achieved by the above components is as follows: by setting up the cleaning components, when cleaning the filter bag, the drive mechanism causes the rotating rod to rotate, which causes the bristles to rotate accordingly, thereby scraping off the dust attached to the outer wall, and thus achieving the effect of cleaning the filter bag as much as possible.

[0007] Preferably, a rotating ring is rotatably connected to one side of the inner wall of the dust collector, and the rotating ring and the rotating rod are fixedly connected.

[0008] The effect achieved by the above components is that the rotating ring rotates, causing the rotating rod to rotate.

[0009] Preferably, the inner arc surface of the filter bag is provided with an active rotating magnetic ring, and the inner arc surface of the rotating ring is fixedly connected with a driven rotating magnetic ring, and the active rotating magnetic ring and the driven rotating magnetic ring attract each other.

[0010] The effect achieved by the above components is as follows: the active rotating magnetic ring rotates, attracting the driven rotating magnetic ring, causing the driven rotating magnetic ring to rotate, and thus the rotating ring rotates.

[0011] Preferably, a mounting bracket is fixedly connected to the inner wall of the blow pipe, and a rotating shaft is provided at the upper end of the mounting bracket via a bearing. A connecting rod is fixedly connected between the rotating shaft and the active rotating magnetic ring.

[0012] The effect achieved by the above components is that the rotation of the shaft causes the active rotating magnetic ring connected to the connecting rod to rotate.

[0013] Preferably, a wind turbine is fixedly connected to the arc surface of the rotating shaft, and the wind turbine is located above the mounting frame.

[0014] The effect achieved by the above components is as follows: compressed air is ejected from the blowpipe, causing the filter bag to be ejected, which in turn causes the wind turbine to rotate, and the shaft to rotate.

[0015] Preferably, a fixing component is provided between the filter bag and the dust collection box. The fixing component includes a circular rod fixedly connected to one side of the filter bag, the circular rod being inserted into the dust collection box, a trapezoidal block being slidably inserted into the arc surface of the circular rod, and a spring being fixedly connected between the trapezoidal block and the circular rod.

[0016] The effect achieved by the above components is as follows: dragging the filter bag causes the trapezoidal block to contact the dust collection box, which in turn pushes the trapezoidal block back into the filter bag, compressing the spring. Once the trapezoidal block is fully retracted into the filter bag, the spring returns to its original position, allowing the trapezoidal block to be inserted into the dust collection box, thereby fixing the filter bag and the dust collection box.

[0017] Preferably, a pull rope is fixedly connected to one end of the trapezoidal block, the pull rope passes through the circular rod, and a pull ring is provided above the filter bag.

[0018] The effect achieved by the above components is: pulling the pull rope causes the trapezoidal block to retract into the filter bag, and then dragging the filter bag to disassemble it.

[0019] Preferably, the pull ring and the pull rope are fixedly connected, and a sealing ring is provided between the filter bag and the dust collection box.

[0020] The effect achieved by the above components is to seal the filter bag and the dust collection box by setting a sealing ring.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting up a cleaning component, when cleaning the filter bag, the driving mechanism causes the rotating rod to rotate, which in turn causes the brush bristles to rotate, thereby scraping off the dust attached to the outer wall and thus achieving the effect of cleaning the filter bag as much as possible. This solves the problem that although the blowpipe sprays compressed air into the filter bag, which can cause the filter bag to expand and shake rapidly, thus removing the dust on the inner wall of the filter bag, it cannot effectively shake off the dust attached to the outer wall of the filter bag, especially when the filter bag is large, resulting in incomplete dust removal from the filter bag.

[0031] Reference Figure 1 and Figure 2 as well as Figure 3 As shown, this utility model provides a technical solution: a calcium hydroxide processing, pulverizing and dust removal equipment includes a dust collection box 1 and an air inlet 8 fixedly connected to the right end of the dust collection box 1. An exhaust pipe 4 is fixedly connected to the upper end of the dust collection box 1, and a fan 5 is installed at the other end of the exhaust pipe 4.

The cleaning component 2 includes a rotating rod 21 disposed on the arc surface of the filter bag 9. A brush bristle 22 is fixedly connected to one side of the rotating rod 21. By setting the cleaning component 2, when cleaning the filter bag 9, the rotating rod 21 is rotated by the driving mechanism, causing the brush bristle 22 to rotate accordingly, thereby scraping off the dust attached to the outer wall, thus achieving the effect of cleaning the filter bag 9 as much as possible. A rotating ring 23 is rotatably connected to one side of the inner wall of the dust collector 1. The rotating ring 23 and the rotating rod 21 are fixedly connected. When the rotating ring 23 rotates, the rotating rod 21 rotates. An active rotating magnetic ring 25 is disposed on the inner arc surface of the filter bag 9, and a driven magnetic ring 25 is fixedly connected to the inner arc surface of the rotating ring 23. Rotating magnetic ring 24, active rotating magnetic ring 25 and driven rotating magnetic ring 24 attract each other. The active rotating magnetic ring 25 rotates, attracting the driven rotating magnetic ring 24, causing the driven rotating magnetic ring 24 to rotate, which in turn causes the rotating ring 23 to rotate. A mounting bracket 29 is fixedly connected to the inner wall of the blow pipe 10. A rotating shaft 26 is provided at the upper end of the mounting bracket 29 and is rotatably connected by a bearing. A connecting rod 27 is fixedly connected between the rotating shaft 26 and the active rotating magnetic ring 25. The rotation of the rotating shaft 26 causes the active rotating magnetic ring 25 connected by the connecting rod 27 to rotate. A wind turbine 28 is fixedly connected to the arc surface of the rotating shaft 26. The wind turbine 28 is located above the mounting bracket 29. The blow pipe 10 sprays compressed air, which sprays out the filter bag 9, causing the wind turbine 28 to rotate, which in turn causes the rotating shaft 26 to rotate.

[0033] Reference Figure 6 As shown in this embodiment: a fixing component 3 is provided between the filter bag 9 and the dust collection box 1. The fixing component 3 includes a circular rod 31 fixedly connected to one side of the filter bag 9. The circular rod 31 is inserted into the dust collection box 1. A trapezoidal block 32 is slidably inserted into the arc surface of the circular rod 31. A spring 33 is fixedly connected between the trapezoidal block 32 and the circular rod 31. Dragging the filter bag 9 causes the trapezoidal block 32 to contact the dust collection box 1, pushing the trapezoidal block 32 back to the filter bag 9, thus compressing the spring 33. When the trapezoidal block 32 is completely retracted into the filter bag 9, the spring 33 returns to its original position. The trapezoidal block 32 is inserted into the dust collector 1, thereby fixing the filter bag 9 and the dust collector 1. One end of the trapezoidal block 32 is fixedly connected to a pull rope 34, which passes through the circular rod 31. A pull ring 35 is provided above the filter bag 9. Pulling the pull ring 35 causes the pull rope 34 to be pulled, causing the trapezoidal block 32 to retract into the filter bag 9. Then, the filter bag 9 is dragged to disassemble it. The pull ring 35 and the pull rope 34 are fixedly connected. A sealing ring 36 is provided between the filter bag 9 and the dust collector 1 to seal the filter bag 9 and the dust collector 1.

[0034] Working principle:

[0035] When using dust removal equipment (model DMC-24 pulse bag dust collector is optional), the pretreatment and filtration stages are as follows: Dust-laden gas enters through inlet 8 of dust collection box 1. Large dust particles settle directly into the ash hopper due to gravity, while fine dust rises with the airflow to the filter bag 9 area, where it is intercepted by the fiber layer of the filter bag 9. The purified gas passes through the filter bag 9 into the clean air chamber and is discharged through the discharge pipe 4 and fan 5. The dust removal trigger condition is that dust accumulation on the surface of the filter bag 9 causes the equipment resistance to rise to a set value, and the differential pressure sensor sends a signal to the PLC. The dust removal process is initiated, specifically the pulse jet cleaning stage: The clean air outlet valve of the current filter bag chamber 9 is closed, stopping the filtration airflow. The electromagnetic pulse valve opens instantaneously, and compressed air enters the jet pipe 10 through the air inlet 7 and air inlet pipe 6, then is injected into the filter bag 9. The high-pressure airflow induces 5-7 times the amount of secondary air into the filter bag 9, causing the filter bag 9 to expand and shake rapidly. Adhering dust falls off into the ash hopper under the action of the reverse airflow and mechanical vibration. The filtration recovery stage: After the dust removal is completed, the clean air outlet valve reopens, and the filter bag chamber 9 resumes filtration. Internal dust is periodically discharged through the ash discharge valve. During filter bag 9 cleaning, compressed air is sprayed from the blowpipe 10, causing the filter bag 9 to be ejected. This rotates the wind turbine 28, which in turn rotates the shaft 26, causing the active rotating magnetic ring 25 connected to the connecting rod 27 to rotate. This attracts the driven rotating magnetic ring 24, causing the driven rotating magnetic ring 24 to rotate, which in turn rotates the rotating ring 23, causing the rotating rod 21 to rotate. The brush bristles 22 then follow suit, scraping off the dust adhering to the outer wall, thus achieving the goal of cleaning the filter bag 9 as much as possible. Move the filter bag 9 so that the trapezoidal block 32 comes into contact with the dust collector 1, causing the trapezoidal block 32 to retract into the filter bag 9, compressing the spring 33. Once the trapezoidal block 32 is fully retracted into the filter bag 9, the spring 33 returns to its original position, allowing the trapezoidal block 32 to be inserted into the dust collector 1, thereby fixing the filter bag 9 and the dust collector 1. Pull the pull ring 35 so that the pull rope 34 is pulled, causing the trapezoidal block 32 to retract into the filter bag 9. Then drag the filter bag 9 to disassemble it. By setting the sealing ring 36, the filter bag 9 and the dust collector 1 are sealed.
