Description

Technical Field

[0001] The invention belongs to the technical field of antimony white powder degassing, in particular to an antimony white powder degassing device. Background Art

[0002] Degassing of antimony dioxide is an important link in the production process of antimony dioxide. Due to high-temperature volatilization, a large amount of gas is mixed in the antimony dioxide. It takes a lot of time for the gas mixed in the antimony dioxide to evaporate naturally. In order to ensure the production efficiency of the enterprise, the gas mixed in the antimony dioxide can be effectively removed through degassing equipment.

[0003] The patent with publication number CN110642291A discloses an antimony white powder degassing device, including a shell, a filter module is arranged in the shell, the upper end of the filter module is sealedly connected to the upper end of the shell, the lower end of the filter module is sealedly connected to the lower end of the shell, the filter module and the shell are gap-matched in the shell cavity, and an exhaust port is arranged on one side of the shell to connect to a vacuum pump. The present invention generates a suction force inside the exhaust port through a vacuum pump, so that the gas entrained in the antimony white powder is sucked away, and the antimony white powder itself is filtered in the filter module, so that the gas entrained in the production of the antimony white powder can be discharged as soon as possible, thereby improving the efficiency of the antimony white powder degassing and ensuring that the company's assembly line can produce quickly and continuously.

[0004] In the above scheme, a vibration module is provided on one side of the shell, and the gas entrained in the antimony white powder can be extracted by a vacuum pump. Since the powdered object is light in weight, the antimony white powder will be adsorbed on the inner wall of the filter module. The vibration generated by the vibration module will cause the antimony white powder adsorbed on the inner wall of the filter module to fall off. Since the vacuum pump always maintains suction force on the shell, the force of the antimony white powder adhering to the inner wall of the filter module is very large. The vibration can only cause a small part of the antimony white powder to fall off, and most of the remaining antimony white powder will block the gas from passing through the filter module, thereby reducing the efficiency of the gas passing through the filter module. For this reason, the present invention provides an antimony white degassing device. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0008] Preferably, the spiral conveying shaft includes a shaft body, which is rotatably mounted in the degassing tube, a spiral plate sleeved on the shaft body, a movable rod movably mounted in the shaft body, an inclined plate rotatably sleeved on one end of the movable rod, and arc-shaped sliders fixedly mounted on both ends of the inclined plate, the arc-shaped sliders are fixedly connected to the inner ring of the spiral plate, two groups of rectangular openings are both opened on the shaft body, the first gear is sleeved on one end of the shaft body, the two groups of arc-shaped sliders are respectively located in the two groups of rectangular openings, and the arc-shaped sliders are slidably connected to the rectangular openings, a guide hole is opened in the shaft body, the movable rod is movably inserted into the guide hole, the outer ring of the spiral plate is tightly attached to the inner ring of the degassing tube, and the other end of the movable rod is fixedly connected to the receiving plate;

[0009] The arc-shaped slider drives the spiral plate to move along the shaft toward the buffer area, so that the lower end of the spiral plate extends into the buffer area. When the screw conveyor shaft is driven to rotate, the first gear drives the shaft to rotate, and the shaft drives the spiral plate to rotate through the arc-shaped slider. As the spiral plate rotates, the antimony white powder in the buffer area will be quickly discharged from the discharge port, thereby improving the efficiency of discharging the antimony white powder remaining in the buffer area.

[0010] Preferably, the filter assembly includes a filter mesh belt, which is arranged in an arc-shaped cavity built into the degassing pipe, four groups of guide columns rotatably installed in the arc-shaped cavity for guiding the filter mesh belt, a driving roller arranged above a group of guide columns, the driving roller is fixedly sleeved on the driving shaft, a drum-type brush, the drum-type brush is closely attached to the inner ring of the filter mesh belt, one end of the drum-type brush is rotatably connected to the suction pipe, the four groups of guide columns are closely attached to the inner ring of the filter mesh belt, the filter mesh belt is clamped between the driving roller and a group of guide columns, the driving roller and the drum-type brush are rotatably installed in the arc-shaped cavity, a plurality of groups of through holes are opened on the drum-type brush, an arc-shaped guide groove is opened at the upper port of the exhaust pipe, and the filter mesh belt passes through the arc-shaped guide groove;

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. When the filter assembly is continuously filtering antimony white powder, the rotating spiral conveying shaft can transport away most of the antimony white powder accumulated on the filter assembly, so that a large amount of antimony white powder will not accumulate on the filter assembly, thereby ensuring the efficiency of gas passing through the filter assembly.

[0014] 2. When discharging the antimony white powder remaining in the buffer area, the cylinder pulls the receiving plate, guide column, and sealing plate to move away from the discharge port. The receiving plate will pull the movable rod to slide along the guide hole, and the receiving plate drives the inclined plate and the arc-shaped slider to move together. The arc-shaped slider drives the spiral plate to move along the shaft toward the buffer area, so that the lower end of the spiral plate extends into the buffer area. When the screw conveyor shaft is driven to rotate, the first gear drives the shaft to rotate, and the shaft drives the spiral plate to rotate through the arc-shaped slider. As the spiral plate rotates, the antimony white powder in the buffer area will be quickly discharged from the discharge port, thereby improving the efficiency of discharging the antimony white powder remaining in the buffer area.

[0015] 3. When the filter assembly is filtering the antimony white powder, the part of the filter belt at the upper end of the exhaust pipe is filtering the antimony white powder, and at the same time, the rotating drive shaft will drive the drive roller to rotate.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] Embodiment 1

[0028] like Figures 1 to 3 As shown, an antimony white powder degassing device described in an embodiment of the present invention comprises a degassing pipe 1, a spiral conveying shaft 2 is rotatably installed in the degassing pipe 1, a first gear 3 is fixedly sleeved on one end of the spiral conveying shaft 2, the first gear 3 meshes with the second gear 4, the middle of the second gear 4 is fixedly connected to the driving shaft 5, the driving shaft 5 is rotatably installed on the degassing pipe 1, an exhaust pipe 6 is embedded and installed below the degassing pipe 1, a filter assembly 7 for filtering antimony white powder is arranged at the upper end of the exhaust pipe 6, the lower end of the degassing pipe 1 is connected to a transfer pipe 8, a switch mechanism 9 is arranged in the transfer pipe 8, the switch mechanism 9 comprises a blocking plate 901, and the lower end of the degassing pipe 1 is opened. A discharge port 101 is provided, a sealing plate 901 is located inside the discharge port 101, two groups of guide pillars 902 movably plugged into the sealing plate 901, a spring 903 sleeved on the guide pillars 902, a receiving plate 904, two groups of guide pillars 902 are fixedly connected to the receiving plate 904, a cylinder 905, the cylinder 905 is fixedly installed in the degassing pipe 1, the piston rod of the cylinder 905 is fixedly connected to the receiving plate 904, two groups of rectangular openings 21 are provided on the spiral conveying shaft 2, the two groups of rectangular openings 21 are located above the exhaust pipe 6, a buffer area 103 is provided at the oblique lower end of the degassing pipe 1, and the discharge port 101 is connected to the buffer area 103.

[0029] Specifically, the degassing pipe 1 is inclined, the interior of the spiral conveying shaft 2 is hollow, and one end of the spiral conveying shaft 2 extends into the antimony white powder production equipment. The lower end of the transfer pipe 8 is connected to the next process equipment. The sealing plate 901 is coated with a rubber layer. In the initial state, the discharge port 101 is blocked by the sealing plate 901. The exhaust pipe 6 is connected to the vacuum pump. When the produced antimony white powder needs to be degassed, the driving shaft 5 is rotated together with the second gear 4 through the motor. The second gear 4 rotates the spiral conveying shaft 2 inside the degassing pipe 1 through the first gear 3, and then the vacuum pump is started. The vacuum pump sucks the inside of the degassing pipe 1 through the exhaust pipe 6. Under the action of the pressure difference, the antimony white powder in the antimony white powder production equipment is discharged. It is sucked into the spiral conveying shaft 2, and the antimony white powder flows into the degassing pipe 1 through the rectangular opening 21 on the spiral conveying shaft 2. The gas mixed in the antimony white powder will be discharged through the exhaust pipe 6, and the antimony white powder is filtered on the filter component 7 at the upper end of the exhaust pipe 6, so that the antimony white powder is accumulated on the filter component 7. Since the rotating spiral conveying shaft 2 has a conveying effect on the antimony white powder accumulated on the filter component 7, the antimony white powder accumulated on the filter component 7 is conveyed by the spiral conveying shaft 2 toward the discharge port 101. As the antimony white powder continues to move toward the discharge port 101, the antimony white powder will be stored in the buffer area 103 in the spiral conveying shaft 2. When the buffer area 103 is full of antimony white powder, the spiral conveying shaft 2 continues to The antimony white powder continues to be conveyed to the buffer area 103. The antimony white powder in the buffer area 103 will be subjected to a thrust toward the discharge port 101. The antimony white powder in the buffer area 103 will squeeze the blocking plate 901 in the discharge port 101, causing the blocking plate 901 to retreat along the guide column 902 and compress the spring 903 to release the blocking of the discharge port 101 by the blocking plate 901. The antimony white powder in the buffer area 103 will flow into the transfer tube 8 through the discharge port 101. Since the amount of antimony white powder flowing out of the discharge port 101 is equal to the amount of antimony white powder conveyed to the buffer area 103 by the spiral conveying shaft 2, the buffer area 103 will always be in a full state of antimony white powder, preventing outside air from entering through the discharge port 101. In the degassing pipe 1, the sealing performance of the degassing pipe 1 is ensured. When the produced antimony white powder is degassed, the cylinder 905 is started. The cylinder 905 pulls the receiving plate 904, the guide column 902, and the sealing plate 901 to move away from the discharge port 101, so that the discharge port 101 is opened. By continuing to rotate the spiral conveying shaft 2, the antimony white powder remaining in the buffer area 103 flows into the transfer pipe 8 through the discharge port 101. Compared with the prior art, during the process of continuous filtering of the antimony white powder by the filter component 7, the rotating spiral conveying shaft 2 can transport away most of the antimony white powder accumulated on the filter component 7, so that a large amount of antimony white powder will not accumulate on the filter component 7, thereby ensuring the efficiency of the gas passing through the filter component 7.

[0030] like Figure 2 and Figure 4As shown, the spiral conveying shaft 2 includes a shaft body 201, which is rotatably installed in the degassing tube 1, a spiral plate 202 sleeved on the shaft body 201, a movable rod 203 movably installed in the shaft body 201, an inclined plate 204 rotatably sleeved on one end of the movable rod 203, and arc-shaped sliders 205 fixedly installed at both ends of the inclined plate 204, and the arc-shaped sliders 205 are fixedly connected to the inner ring of the spiral plate 202. Two groups of rectangular openings 21 are both opened on the shaft body 201, and the first gear 3 is sleeved on one end of the shaft body 201. The two groups of arc-shaped sliders 205 are respectively located in the two groups of rectangular openings 21, and the arc-shaped sliders 205 are slidably connected to the rectangular openings 21. A guide hole 2011 is opened in the shaft body 201, and the movable rod 203 is movably inserted into the guide hole 2011. The outer ring of the spiral plate 202 is close to the inner ring of the degassing tube 1, and the other end of the movable rod 203 is fixedly connected to the receiving plate 904.

[0031] Specifically, after the degassing of the antimony white powder is completed, the discharge port 101 is opened, and the antimony white powder remaining in the buffer area 103 is discharged from the discharge port 101 by rotating the spiral conveyor shaft 2. Since the spiral conveyor shaft 2 cannot convey the antimony white powder in the buffer area 103, the antimony white powder remaining in the buffer area 103 is discharged from the discharge port 101 at a relatively slow efficiency. Therefore, when discharging the antimony white powder remaining in the buffer area 103, the cylinder 905 pulls the receiving plate 904, the guide column 902, and the blocking plate 901 to move away from the discharge port 101. The receiving plate 904 will pull the movable rod 203 along the guide column 902 to move the receiving plate 904 away from the discharge port 101. It slides toward the hole 2011, and the receiving plate 904 drives the inclined plate 204 and the arc-shaped slider 205 to move together. The arc-shaped slider 205 drives the spiral plate 202 to move along the shaft body 201 toward the buffer area 103, so that the lower end of the spiral plate 202 extends into the buffer area 103. When the screw conveyor shaft 2 is driven to rotate, the first gear 3 drives the shaft body 201 to rotate, and the shaft body 201 drives the spiral plate 202 to rotate through the arc-shaped slider 205. As the spiral plate 202 rotates, the antimony white powder in the buffer area 103 will be quickly discharged from the discharge port 101, thereby improving the efficiency of discharging the antimony white powder remaining in the buffer area 103.

[0032] Embodiment 2

[0033] like Figures 5 to 8As shown in the comparative example 1, another embodiment of the present invention is as follows: the filter assembly 7 includes a filter mesh belt 701, the filter mesh belt 701 is arranged in the arc cavity 102 built in the degassing tube 1, four groups of guide posts 702 rotatably installed in the arc cavity 102 for guiding the filter mesh belt 701, a driving roller 703 arranged above a group of guide posts 702, the driving roller 703 is fixedly sleeved on the driving shaft 5, and a drum brush 704, the drum brush 704 is closely attached to the filter mesh belt 70 1, one end of the drum brush 704 is rotatably connected to the suction pipe 705, the four groups of guide pillars 702 are all close to the inner circle of the filter belt 701, the filter belt 701 is clamped between the driving roller 703 and a group of guide pillars 702, the driving roller 703 and the drum brush 704 are both rotatably installed in the arc cavity 102, a plurality of groups of through holes 7041 are opened on the drum brush 704, an arc guide groove 601 is opened at the upper end of the exhaust pipe 6, and the filter belt 701 passes through the arc guide groove 601.

[0034] Specifically, the suction pipe 705 is connected to the vacuum cleaner. As the filter assembly 7 continuously filters the antimony white powder, the inside of the filter assembly 7 will be blocked by the antimony white powder. In the process of cleaning the blockage of the filter assembly 7, the entire device will be shut down, reducing the degassing efficiency of the entire device for the antimony white powder. Therefore, when the filter assembly 7 filters the antimony white powder, the part of the filter belt 701 at the upper end of the exhaust pipe 6 filters the antimony white powder, and at the same time, the rotating drive shaft 5 drives the drive roller 703 to rotate. As the drive roller 703 rotates, the drive roller 703 drives the filter belt 701 to make a circular motion around the four sets of guide columns 702. During the circular motion of the filter belt 701, the filter belt 701 will slide along the arc-shaped guide groove 601 at the upper end of the exhaust pipe 6, so that the filter belt 701 at the exhaust pipe 6 is The filter belt 701 at the upper end of the tube 6 is continuously replaced, and the roller brush 704 is driven by a motor to rotate. The rotating roller brush 704 cleans the antimony white powder attached to and blocked on the filter belt 701, and the running vacuum cleaner causes the suction pipe 705 to generate suction to the inside of the roller brush 704. Under the action of the pressure difference, the through hole 7041 opened on the roller brush 704 generates suction, so that the antimony white powder floating around is sucked away by the through hole 7041, and the antimony white powder is prevented from falling on the filter belt 701 for the second time. During the filtering process of the antimony white powder by the filter belt 701, the transmission and cleaning of the filter belt 701 itself are realized simultaneously, thereby ensuring the filtering effect of the filter belt 701 on the antimony white powder, and improving the degassing efficiency of the entire device on the antimony white powder.

[0035] Working principle: the driving shaft 5 is rotated together with the second gear 4 through the motor, and the second gear 4 rotates the spiral conveying shaft 2 inside the degassing tube 1 through the first gear 3, and then the vacuum pump is started. The vacuum pump sucks the inside of the degassing tube 1 through the exhaust pipe 6. Under the action of the pressure difference, the antimony white powder in the antimony white powder production equipment is sucked into the spiral conveying shaft 2, and the antimony white powder flows into the degassing tube 1 through the rectangular opening 21 on the spiral conveying shaft 2. The gas mixed in the antimony white powder will be discharged through the exhaust pipe 6, and the antimony white powder is filtered on the filter component 7 at the upper end of the exhaust pipe 6, so that the antimony white powder is accumulated on the filter component 7. Since the rotating spiral conveying shaft 2 has a conveying effect on the antimony white powder accumulated on the filter component 7, the antimony white powder accumulated on the filter component 7 is conveyed by the spiral conveying shaft 2 toward the discharge port 101. As the antimony white powder continues to move toward the discharge port 101, the antimony white powder will be stored on the spiral conveying shaft 2. When the buffer area 103 is filled with antimony white powder, the spiral conveying shaft 2 continues to convey the antimony white powder to the buffer area 103, and the antimony white powder in the buffer area 103 will be pushed toward the discharge port 101, and the antimony white powder in the buffer area 103 will squeeze the blocking plate 901 in the discharge port 101, so that the blocking plate 901 retreats along the guide column 902, and compresses the spring 903, so that the blocking plate 901 releases the sealing of the discharge port 101. The antimony white powder in the buffer area 103 will flow into the transfer tube 8 through the discharge port 101. When the produced antimony white powder is degassed, the cylinder 905 is started, and the cylinder 905 pulls the receiving plate 904, the guide column 902, and the blocking plate 901 to move away from the discharge port 101, so that the discharge port 101 is opened. By continuing to rotate the spiral conveying shaft 2, the antimony white powder remaining in the buffer area 103 flows into the transfer tube 8 through the discharge port 101;

[0036] When discharging the antimony white powder remaining in the buffer area 103, the cylinder 905 pulls the receiving plate 904, the guide column 902, and the blocking plate 901 to move away from the discharge port 101. The receiving plate 904 will pull the movable rod 203 to slide along the guide hole 2011, and the receiving plate 904 drives the inclined plate 204 and the arc-shaped slider 205 to move together. The arc-shaped slider 205 drives the spiral plate 202 to move along the shaft body 201 toward the buffer area 103, so that the lower end of the spiral plate 202 extends into the buffer area 103. When the screw conveying shaft 2 is driven to rotate, the first gear 3 drives the shaft body 201 to rotate, and the shaft body 201 drives the spiral plate 202 to rotate through the arc-shaped slider 205. As the spiral plate 202 rotates, the antimony white powder in the buffer area 103 will be quickly discharged from the discharge port 101.

[0037] When the filter assembly 7 filters the antimony white powder, the part of the filter belt 701 at the upper end of the exhaust pipe 6 filters the antimony white powder, and at the same time, the rotating drive shaft 5 drives the drive roller 703 to rotate. As the drive roller 703 rotates, the drive roller 703 drives the filter belt 701 to make a circular motion around the four groups of guide columns 702. During the circular motion of the filter belt 701, the filter belt 701 will slide along the arc-shaped guide groove 601 at the upper end of the exhaust pipe 6, so that the filter belt 701 at the upper end of the exhaust pipe 6 can be easily filtered. The filter belt 701 is constantly replaced, and the motor drives the roller brush 704 to rotate. The rotating roller brush 704 cleans the antimony white powder attached to and blocked on the filter belt 701, and the running vacuum cleaner causes the suction pipe 705 to generate suction to the inside of the roller brush 704. Under the action of the pressure difference, the through hole 7041 opened on the roller brush 704 generates suction, so that the antimony white powder floating around is sucked away by the through hole 7041, thereby preventing the antimony white powder from falling on the filter belt 701 for the second time.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
