Description

Technical Field

[0001] This utility model relates to the field of spraying technology in cement production, and in particular to a spraying dust removal machine for cement production. Background Technology

[0002] Cement is a powdery hydraulic inorganic binder. Its main components include silicate cement clinker, gypsum, and admixtures. Silicate cement clinker is made by calcining limestone, clay, and iron ore powder in a specific ratio. Its main mineral components include tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium aluminoferrite. Gypsum is used to regulate the setting time of cement, while admixtures can improve certain properties of cement, such as reducing heat of hydration and improving corrosion resistance. Cement production generates a large amount of dust, such as during raw material crushing, grinding, conveying, and packaging. If this dust is not controlled, it can cause serious pollution to the surrounding environment and harm human health. Spray dust collectors use water mist to combine dust with the water mist and cause it to settle, effectively reducing the concentration of dust in the air, ensuring that cement production meets environmental standards, and reducing pollution to the atmospheric environment.

[0003] A search revealed a Chinese patent with authorization number CN220656875U, which discloses a spray dust removal device for cement production, relating to the field of spray dust removal technology in cement production. The device includes a dust collection box with guide plates fixedly installed on both inner side walls, and an air inlet pipe fixedly installed on the side wall below the guide plates. This patent has the following shortcomings: Existing cement dust, after entering the dust collection box, automatically rises. Even with timely spraying, some dust floats to the top inner wall of the dust collection box, making complete settling difficult. Over time, this leads to a large amount of cement dust and water mixture adhering to the top inner wall of the dust collection box, making cleaning difficult and reducing the equipment's lifespan. Furthermore, spraying alone is inefficient for dust suppression, failing to quickly mix the cement dust with the spraying agent and water for effective dust settling. Currently, to reuse water resources, a filter plate is typically used to spray cement dust and then filter the water flow for reuse. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that cement dust tends to float upwards and stick to the top inner wall of the dust collector after entering the dust collector, resulting in incomplete dust suppression. Therefore, this invention proposes a spray dust collector for cement production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A spray dust collector for cement production includes a dust collection box and a spray agent box. A motor is fixedly installed at the bottom of the dust collection box, and a filter plate is installed inside the dust collection box. The dust collector also includes: a rotating rod fixedly connected to the output end of the motor; a connecting rod fixedly connected to the top right side of the rotating rod, and a first trapezoidal block fixedly connected to the right end surface of the connecting rod; and a blower fixedly connected to the top inner wall of the dust collection box.

[0007] Preferably, a water pump is fixedly installed on the top surface of the dust collection box, a water suction pipe is fixedly connected between the spray tank and the water pump, water collection pipes are fixedly installed on the inner walls of the top two sides of the dust collection box, and a dust suction pipe is fixedly connected to the bottom left side of the dust collection box.

[0008] Preferably, an inlet pipe is fixedly connected between the water collection pipe and the water pump, the inlet pipe passes through the dust collector and is fixedly connected to the dust collector, and multiple spray hoods are fixedly connected to the bottom of the water collection pipe.

[0009] Preferably, the rotating rod passes through the dust collector and is rotatably connected to the dust collector; a fixing rod is fixedly connected to the inner left side wall of the dust collector; and a drain pipe is fixedly connected to the bottom surface of the dust collector.

[0010] Preferably, an exhaust pipe is fixedly connected to the top of the dust collector, and a ring is fixedly connected to the end of the fixing rod away from the inner wall of the dust collector, with a sliding rod passing through the surface of the ring.

[0011] Preferably, the sliding rod is slidably connected to the ring, an upper top plate is fixedly connected to the top surface of the sliding rod, and a second trapezoidal block is fixedly connected to the bottom surface of the sliding rod, with the inclined surface of the second trapezoidal block slidably connected to the inclined surface of the first trapezoidal block.

[0012] Preferably, a first spring is sleeved on the surface of the sliding rod, one end of the first spring is fixedly connected to the second trapezoidal block, and the other end of the first spring is fixedly connected to the ring.

[0013] Preferably, a fixing plate is fixedly connected to the inner walls of both sides of the dust collector, a guide rod is passed through the surface of the fixing plate, the guide rod is slidably connected to the fixing plate, the bottom of the guide rod is fixedly connected to the filter plate, a second spring is sleeved on the surface of the guide rod, one end of the second spring is fixedly connected to the fixing plate, and the other end of the second spring is fixedly connected to the filter plate.

[0014] Compared with the prior art, this utility model provides a spray dust collector for cement production, which has the following beneficial effects:

[0015] This spray dust collector for cement production uses a blower to blow cement dust downwards and mix it with the spraying agent for dust suppression. This prevents cement dust from floating upwards and sticking to the top inner wall of the dust collector after entering it, thus ensuring complete dust suppression. Simultaneously, the motor drives the rotating rod to rotate, which in turn drives the connecting rod to rotate the first trapezoidal block, causing it to contact the second trapezoidal block. This causes the second trapezoidal block to slide upwards along the sliding rod, compressing the first spring and pushing the top plate upwards against the bottom of the filter plate. The filter plate then compresses the second spring upwards through the guide rod. After the first and second trapezoidal blocks separate, the first spring automatically causes the sliding rod to automatically reset the top plate and the second trapezoidal block. The second spring then automatically ejects the filter plate downwards, causing it to vibrate. The first trapezoidal block then contacts the second trapezoidal block again, and this process repeats. This continuous up-and-down vibration of the filter plate during the filtration of cement dust, spraying agent, and water prevents the cement mixture from clogging the filter plate and improves the efficiency of cement dust suppression.

[0027] Reference Figures 1-8 A spray dust collector for cement production includes a dust collection box 1 and a spray agent box 2. A motor 3 is fixedly installed at the bottom of the dust collection box 1, and a filter plate 4 is installed inside the dust collection box 1. The dust collector also includes: a rotating rod 5, fixedly connected to the output end of the motor 3; a connecting rod 6, fixedly connected to the top right side of the rotating rod 5, with a first trapezoidal block 7 fixedly connected to the right end surface of the connecting rod 6; and a blower 8, fixedly connected to the top inner wall of the dust collection box 1. When cement dust is sucked into the dust collection box 1, the blower 8 is activated, which blows the cement dust downwards to mix with the spray agent, thus performing a dust suppression operation. This prevents the cement dust from floating upwards and sticking to the top inner wall of the dust collection box 1 after entering it, helping to completely suppress the cement dust.

[0028] A water pump 10 is fixedly installed on the top surface of the dust collection box 1. A water suction pipe 11 is fixedly connected between the spray tank 2 and the water pump 10. Water collection pipes 12 are fixedly installed on the inner walls of the top two sides of the dust collection box 1. A dust suction pipe 25 is fixedly connected to the bottom left side of the dust collection box 1.

[0029] A water inlet pipe 13 is fixedly connected between the water collection pipe 12 and the water pump 10. The water inlet pipe 13 passes through the dust collection box 1 and is fixedly connected to the dust collection box 1. Multiple spray hoods 14 are fixedly connected to the bottom of the water collection pipe 12. Spraying agent can be drawn from the spraying agent box 2 through the water pump 10 and the suction pipe 11, enters the water collection pipe 12 through the water inlet pipe 13, and then sprays out through the spray hoods 14 to suppress the cement dust in the dust collection box 1. The settled dust falls onto the filter plate 4, and the filtered spraying agent and water are filtered through the filter plate 4 and fall to the bottom of the dust collection box 1 for collection so that they can be reused.

[0030] The rotating rod 5 passes through the dust collection box 1 and is rotatably connected to the dust collection box 1. A fixing rod 16 is fixedly connected to the inner left side of the dust collection box 1. A drain pipe 9 is fixedly connected to the bottom surface of the dust collection box 1. The filtered spray and water can be discharged from the drain pipe 9 for collection and then reuse.

[0031] An exhaust pipe 15 is fixedly connected to the top of the dust collector 1. A ring 17 is fixedly connected to the end of the fixed rod 16 away from the inner wall of the dust collector 1. A sliding rod 18 passes through the surface of the ring 17. After the cement dust is treated, the air inside the dust collector 1 can be discharged from the exhaust pipe 15. The ring 17 can guide the sliding rod 18 up and down, which helps to make the sliding rod 18 slide up and down more stably.

[0032] The sliding rod 18 is slidably connected to the ring 17. The top surface of the sliding rod 18 is fixedly connected to the upper top plate 19, and the bottom surface of the sliding rod 18 is fixedly connected to the second trapezoidal block 20. The inclined surface of the second trapezoidal block 20 is slidably connected to the inclined surface of the first trapezoidal block 7. By starting the motor 3, the rotating rod 5 can be driven to rotate. The rotating rod 5 drives the connecting rod 6 and the first trapezoidal block 7 to rotate, so that the inclined surface of the first trapezoidal block 7 abuts against the inclined surface of the second trapezoidal block 20. This allows the second trapezoidal block 20 to slide upward within the ring 17 via the sliding rod 18, thereby driving the upper top plate 19 to slide upward and abut against the bottom of the filter plate 4, and causing the filter plate 4 to move upward.

[0033] A first spring 21 is sleeved on the surface of the sliding rod 18. One end of the first spring 21 is fixedly connected to the second trapezoidal block 20, and the other end of the first spring 21 is fixedly connected to the ring 17. When the sliding rod 18 slides upward, it will compress the first spring 21. When the first trapezoidal block 7 and the second trapezoidal block 20 are separated, the first spring 21 can cause the sliding rod 18 to drive the second trapezoidal block 20 to automatically return downward.

[0034] Fixed plates 22 are fixedly connected to the inner walls of both sides of the dust collector 1. Guide rods 23 penetrate the surface of the fixed plates 22 and are slidably connected to the fixed plates 22. The bottom of the guide rods 23 is fixedly connected to the filter plate 4. A second spring 24 is sleeved on the surface of the guide rods 23. One end of the second spring 24 is fixedly connected to the fixed plates 22 and the other end of the second spring 24 is fixedly connected to the filter plate 4. When the filter plate 4 is pushed upward, the second spring 24 is compressed by the guide rods 23. Then, when the second trapezoidal block 20 is reset downward, the second spring 24 can make the filter plate 4 automatically reset downward and generate vibration. This operation is repeated to make the filter plate 4 continuously vibrate, which can prevent the mixture of cement dust and water from clogging the filter screen and facilitate the rapid separation of spraying agent and water from cement dust.

[0035] In this invention, when cement dust needs to be treated, the cement dust is sucked into the dust collector 1 through the suction pipe 25. The blower 8, water pump 10, and motor 3 are then activated. The water pump 10 draws the spray agent and water from the spray agent tank 2 into the dust collector 1, which are then sprayed out from the spray hood 14 to suppress the cement dust. The blower 8 blows the floating dust downwards. Combined with the spray agent and water, this quickly suppresses the cement dust. Simultaneously, the motor 3 drives the rotating rod 5 to rotate. The rotating rod 5, through the connecting rod 6, drives the first trapezoidal block 7 to rotate and contact the second trapezoidal block 20. This causes the second trapezoidal block 20 to slide the sliding rod 18 upwards, simultaneously compressing the first trapezoidal block 7. Spring 21 drives the top plate 19 to push the bottom of the filter plate 4 upward, causing the filter plate 4 to compress the second spring 24 through the guide rod 23. After the first trapezoidal block 7 separates from the second trapezoidal block 20, the first spring 21 automatically causes the sliding rod 18 to drive the top plate 19 and the second trapezoidal block 20 to automatically reset. The second spring 24 automatically pops the filter plate 4 downward to make it vibrate. Then the first trapezoidal block 7 contacts the second trapezoidal block 20 again. This operation repeats, so that the filter plate 4 continuously vibrates up and down when filtering cement dust, spraying agent and water. This can prevent the cement mixture from clogging the filter plate 4 and help improve the efficiency of cement dust suppression.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
