Description

Technical Field

[0001] This utility model relates to the field of calcium fluoride sludge treatment technology, and in particular to a ventilation and dust removal system for a calcium fluoride sludge treatment workshop. Background Technology

[0002] Calcium fluoride sludge treatment refers to the process of reducing, rendering harmless, and recycling calcium fluoride solid waste generated in industrial production. It typically includes sludge dewatering, solidification and stabilization, and impurity separation. Its core objective is to reduce the risk of fluoride pollution and achieve resource recovery. During this process, operations such as sludge mixing, drying, and material transfer easily generate large amounts of calcium fluoride dust. If this dust accumulates in the workshop for a long time, it can not only cause irritation and harm to the respiratory tract and skin of operators, but also potentially cause secondary pollution through air diffusion. Furthermore, dust adhering to equipment surfaces can affect the normal operating life of the equipment. Therefore, ventilation and dust removal in the treatment workshop are essential to ensure production safety, personnel health, and environmental protection. Existing technologies for ventilation and dust removal in calcium fluoride sludge treatment workshops have the following shortcomings: Firstly, traditional ventilation systems often employ a single intake or exhaust design, making it difficult to form a directional and efficient airflow circulation. This leads to the accumulation of smoke and dust in the workshop and poor ventilation. Furthermore, dust removal devices often rely on a single filter layer for processing, lacking a multi-stage purification mechanism. The filtration effect on fine dust is limited, resulting in high dust emission concentrations that are difficult to meet environmental emission standards. Secondly, the filter layers in existing dust removal equipment generally present cleaning and maintenance challenges. They are easily clogged by dust adhesion, leading not only to increased ventilation resistance and decreased filtration efficiency but also requiring frequent shutdowns for replacement, increasing operation and maintenance costs. Therefore, this utility model proposes a ventilation and dust removal system for calcium fluoride sludge treatment workshops to solve the problems existing in the prior art. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a ventilation and dust removal system for a calcium fluoride sludge treatment workshop. This system introduces clean air through multiple sets of inlet fans equipped with filters, and combines this with exhaust air from the side ducts to form a directional airflow circulation, ensuring timely removal of smoke and dust from the workshop. The staggered baffles within the dust removal chamber utilize inertia to achieve initial settling of particulate matter, followed by further filtration of fine dust by filter bags. This dual dust removal mechanism significantly reduces dust emission concentration and effectively minimizes pollution to the external environment.

[0004] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a ventilation and dust removal system for a calcium fluoride sludge treatment workshop, including a treatment workshop, an inlet fan and a dust removal chamber. The inlet fan is located above one side of the treatment workshop, and the dust removal chamber is located above one end of the treatment workshop. A partition is provided in the middle of the interior of the dust removal chamber, and the dust removal chamber is divided into two dust removal chambers by the partition. A duct is connected between the dust removal chamber and the lower part of the interior of the treatment workshop. The dust removal chamber has baffles on the outside, and multiple sets of baffles are arranged at different heights. The dust removal chamber has a frame on the inside, and a filter bag is installed inside the frame. The lower end of the filter bag is connected to the dust removal chamber. An air outlet pipe is provided on one side of the frame, which is connected to the dust removal chamber.

[0005] A further improvement is that a dust collection hopper is provided at the bottom of the dust removal chamber, and a sealed chamber is connected to the lower end of the dust collection hopper. The sealed chamber is connected to the dust collection hopper by bolts and is sealed.

[0006] A further improvement is that an elastic plate is provided at the top inside the frame, the upper end of the filter bag is connected to and closed by the elastic plate, and the lower end of the filter bag is connected to and communicates with the bottom inside the frame.

[0007] A further improvement is that: a rotating arm is rotatably provided at the top inside the frame, and the rotating arm rotates around the center as the fulcrum. A striking block is provided at one end of the rotating arm, and the striking block is used to strike the elastic plate. A spring is connected between the top end of the rotating arm away from the striking block and the top of the frame.

[0008] A further improvement is that a turntable is rotatably provided inside the frame at one end of the rotating arm, and a protrusion is provided at one end of the front side of the turntable. The protrusion is used to press one end of the rotating arm as the turntable rotates.

[0009] A further improvement is that the intake fan is provided in multiple sets, and the input end of the intake fan is provided with a filter.

[0010] A further improvement is that: one side of the processing workshop is provided with windows and doors, and the windows are provided in multiple sets.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model introduces clean air through multiple sets of inlet fans with filters, and forms a directional airflow circulation with the exhaust ducts on both sides to ensure that the smoke and dust in the workshop are removed in time. The staggered baffles in the dust removal chamber use inertia to achieve the initial settling of particulate matter, and the subsequent filter bags further filter fine dust. The dual dust removal mechanism greatly reduces the dust emission concentration, effectively reduces the pollution to the external environment, and at the same time ensures the air quality inside the treatment workshop, providing a safer operating environment for the staff.

[0012] 2. This utility model adopts a linkage mechanism of turntable, rotating arm, striking block and elastic plate. Through mechanical vibration, the impurities attached to the surface of the filter bag are efficiently removed and fall into the closed chamber for centralized collection through the dust collection hopper. This not only avoids the problem of increased ventilation resistance caused by filter bag blockage, but also extends the service life of the filter bag, reduces the cost of frequent filter material replacement, and reduces the risk of secondary pollution.

[0015] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model. Example 1

[0016] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a ventilation and dust removal system for a calcium fluoride sludge treatment workshop, including a treatment workshop 1, an inlet fan 2, and a dust removal chamber 3. The inlet fan 2 is located above one side of the treatment workshop 1, and the dust removal chamber 3 is located above one end of the treatment workshop 1. A partition 5 is provided in the middle of the interior of the dust removal chamber 3, and the dust removal chamber 3 is divided into two dust removal chambers by the partition 5. A duct 4 is connected between the dust removal chamber and the lower part of the interior of the treatment workshop 1. The dust removal chamber has baffles 6 on its outer side, with multiple sets of baffles 6 arranged at different heights. The dust removal chamber has a frame 7 on its inner side, and filter bags 8 are installed inside the frame 7. The lower end of the filter bags 8 connects to the dust removal chamber. One side of the frame 7 has an exhaust pipe 9 connecting to the dust removal chamber 3. In use, external air is introduced into the processing workshop 1 through the inlet fan 2. Exhaust fans are installed inside the processing workshop 1 at the input ends of the air ducts 4 on both sides. The dust from the calcium fluoride sludge treatment in the processing workshop 1 is discharged from both sides into the two sets of dust removal chambers. The airflow first passes through multiple sets of baffles 6 at different heights, colliding with the baffles 6. Due to inertia, the particles settle down. Then, the airflow enters the interior from the bottom of the filter bags 8, is filtered by the filter bags 8, enters the frame 7, and is discharged from the exhaust pipe 9. This facilitates ventilation of the processing workshop 1 and multiple dust removal processes, reducing pollution to the outside environment.

[0017] The bottom of the dust collection chamber is equipped with a dust collection hopper 10, and the lower end of the dust collection hopper 10 is connected to a sealed chamber 11. The sealed chamber 11 is connected to the dust collection hopper 10 by bolts and is sealed. In use, the dust is discharged into the two sets of dust collection chambers from both sides. It first passes through multiple sets of baffles 6 of different heights. The airflow collides with the baffles 6, and the particles settle down due to inertia and fall from the dust collection hopper 10 into the sealed chamber 11 for collection. Subsequently, the filter bag 8 is subjected to knocking and vibration, and the impurities filtered inside also settle down and fall from the dust collection hopper 10 into the sealed chamber 11 for collection.

[0018] An elastic plate 12 is provided at the top inside the frame 7. The upper end of the filter bag 8 is connected to and closed by the elastic plate 12, and the lower end of the filter bag 8 is connected to and communicates with the lower part of the frame 7. A rotating arm 14 is rotatably provided at the top inside the frame 7, and the rotating arm 14 rotates around the center as a fulcrum. A striking block 16 is provided at one end of the rotating arm 14, and the striking block 16 is used to strike the elastic plate 12. A spring 15 is connected between the top end of the rotating arm 14 away from the striking block 16 and the top of the frame 7. A turntable 13 is rotatably provided inside the frame 7 at one end of the rotating arm 14, and a protrusion 17 is provided at the front end of the turntable 13. The protrusion 17 is used to press one end of the rotating arm 14 as the turntable 13 rotates. In use, the motor drives the turntable 13 to rotate, causing the protrusion 17 to rotate around the center of the turntable 13. The protrusion 17 presses down on the rotating arm 14 from above, causing the other end of the rotating arm 14 and the striking block 16 to lift up. The protrusion 17 continues to rotate with the turntable 13. When the protrusion 17 disengages from the rotating arm 14, under the tension of the spring 14, one end of the rotating arm 14 returns to its original position, and the other end hammers down, causing the striking block 16 to strike the elastic plate 12. The elasticity of the elastic plate 12 generates a vibration force that acts on the filter bag 8, which helps the impurities filtered out inside the filter bag 8 to fall off, making collection easier and improving the service life of the filter bag 8, thus extending its service cycle. Example 2

[0019] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a ventilation and dust removal system for a calcium fluoride sludge treatment workshop, including a treatment workshop 1, an inlet fan 2, and a dust removal chamber 3. The inlet fan 2 is located above one side of the treatment workshop 1, and the dust removal chamber 3 is located above one end of the treatment workshop 1. A partition 5 is provided in the middle of the interior of the dust removal chamber 3, and the dust removal chamber 3 is divided into two dust removal chambers by the partition 5. A duct 4 is connected between the dust removal chamber and the lower part of the interior of the treatment workshop 1. The dust removal chamber has baffles 6 on its outer side, with multiple sets of baffles 6 arranged at different heights. The dust removal chamber has a frame 7 on its inner side, and filter bags 8 are installed inside the frame 7. The lower end of the filter bags 8 connects to the dust removal chamber. One side of the frame 7 has an exhaust pipe 9 connecting to the dust removal chamber 3. In use, external air is introduced into the processing workshop 1 through the inlet fan 2. Exhaust fans are installed inside the processing workshop 1 at the input ends of the air ducts 4 on both sides. The dust from the calcium fluoride sludge treatment in the processing workshop 1 is discharged from both sides into the two sets of dust removal chambers. The airflow first passes through multiple sets of baffles 6 at different heights, colliding with the baffles 6. Due to inertia, the particles settle down. Then, the airflow enters the interior from the bottom of the filter bags 8, is filtered by the filter bags 8, enters the frame 7, and is discharged from the exhaust pipe 9. This facilitates ventilation of the processing workshop 1 and multiple dust removal processes, reducing pollution to the outside environment.

[0020] The bottom of the dust collection chamber is equipped with a dust collection hopper 10, and the lower end of the dust collection hopper 10 is connected to a sealed chamber 11. The sealed chamber 11 is connected to the dust collection hopper 10 by bolts and is sealed. In use, the dust is discharged into the two sets of dust collection chambers from both sides. It first passes through multiple sets of baffles 6 of different heights. The airflow collides with the baffles 6, and the particles settle down due to inertia and fall from the dust collection hopper 10 into the sealed chamber 11 for collection. Subsequently, the filter bag 8 is subjected to knocking and vibration, and the impurities filtered inside also settle down and fall from the dust collection hopper 10 into the sealed chamber 11 for collection.

[0021] The intake fan 2 has multiple sets, and the input end of the intake fan 2 is equipped with a filter. In use, outside air is introduced into the processing workshop 1 through the intake fan 2. During this process, the air is filtered through the filter to ensure its cleanliness. One side of the processing workshop 1 is equipped with windows 18 and doors 19, and multiple sets of windows 18 are provided. The doors 19 are used for staff entry and exit, and the windows 18 can be opened or closed.

[0022] The ventilation and dust removal system of this calcium fluoride sludge treatment workshop introduces clean air through multiple sets of filter-equipped intake fans 2, and forms a directional airflow circulation with the exhaust ducts 4 on both sides, ensuring that smoke and dust in the workshop are removed in a timely manner. Inside the dust removal chamber, staggered baffles 6 utilize inertia to achieve initial settling of particulate matter, followed by further filtration of fine dust by filter bags 8. This dual dust removal mechanism significantly reduces dust emission concentration, effectively reducing pollution to the external environment while ensuring air quality inside the treatment workshop, providing a safer operating environment for staff. Simultaneously, a linkage mechanism using a turntable 13, rotating arm 14, striking block 16, and elastic plate 12 uses mechanical vibration to efficiently remove impurities adhering to the surface of the filter bags 8, which then fall into the enclosed chamber 11 for centralized collection via the dust collection hopper 10. This avoids increased ventilation resistance caused by filter bag clogging, extends the service life of the filter bags 8, reduces the cost of frequent filter replacement, and lowers the risk of secondary pollution.
