Description

Technical Field

[0001] The present invention relates to the technical field of dust removal equipment, and particularly to a secondary dust removal cover for a horizontal cement silo. Background Art

[0002] When the existing dust remover at the top of the horizontal cement silo is actually used, there is a defect that the dust removal is not thorough. When filling cement into the cement silo, when the pressure is too high or the remaining cement volume in the tanker is small, the air content in the cement flow increases, and dust will be brought outside the dust remover through the gaps in the cloth bag, causing environmental pollution. Therefore, it is necessary to treat the overflowing dust.

[0003] Most of the existing methods for treating the overflowing dust are to pump the air containing dust into water, and the dust in the air is removed and purified by the water solution. Although this method can purify the dust in the air, in the application process, due to a large amount of dust impurities mixed in the water solution, when the water solution needs to be replaced, the sewage is difficult to quickly drain out of the container, and in this process, the dust removal efficiency is greatly reduced. For this reason, we have proposed a secondary dust removal cover for a horizontal cement silo. Summary of the Invention

[0004] The purpose of the present invention is to solve the above deficiencies and provide a secondary dust removal cover for a horizontal cement silo.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The present invention is implemented by the following technical solutions: A secondary dust removal cover for a horizontal cement silo, including a cover body, a housing provided on one side of the cover body, and a water storage cavity and a purification cavity opened in the housing. The purification mechanism includes an air inlet hole opened on the outer side of the cover body for inhaling air, a fan provided on the top side of the cover body, and a water solution provided inside the purification cavity for removing dust and purifying the air. The input end of the fan is connected to an air inlet pipe communicated with the cover body, and the output end of the fan is connected to an air outlet pipe whose tail end extends into the water solution inside the purification cavity. An air outlet hole for discharging the gas inside the purification cavity is opened on the cover body; through the operation of the purification mechanism, the dust overflowing from the gaps in the cloth bag can be purified.

[0007] The drainage mechanism includes a pressing plate slid in the purification cavity for pressing the water solution and a drainage hole opened on the cover body for discharging the water solution inside the purification cavity. A closing column for closing the drainage hole is slidably connected inside the drainage hole. The housing is provided with a driving mechanism for driving the pressing plate and the closing column to displace. Through the operation of the drainage mechanism, the water solution mixed with a large amount of dust impurities can be discharged, and the drainage hole can be cleaned and dredged to prevent the drainage hole from being blocked by the impurities in the water solution during the drainage process.

[0008] As a further improvement of the above solution, the interior of the water storage cavity stores water liquid, and a liquid level valve for injecting water liquid into the water storage cavity is installed at the top of the housing. Through the liquid level valve, an appropriate amount of water liquid can be injected into the water storage cavity.

[0009] As a further improvement of the above solution, the driving mechanism includes a lead screw threadedly passing through both ends of the pressing plate for driving the pressing plate to perform vertical displacement, and a pushing plate arranged at one end of the housing for driving the closing column to perform horizontal displacement. The end of the closing column located outside the housing is fixed to the pushing plate. A driving rod is arranged on the side of the pushing plate away from the housing. Transmission wheels I are arranged on the outer walls of the top ends of the lead screw and the driving rod. A transmission belt I for transmission cooperation is arranged outside the transmission wheels I. Fixing blocks are fixed at both ends of the side of the pushing plate close to the driving rod. A driving plate I is hinged to the outside of the fixing block. The movable end of the driving plate I is hinged to a driving plate II. The movable end of the driving plate II is fixed with a driving shaft. A transmission wheel II is arranged outside the driving shaft. A transmission wheel III corresponding to the transmission wheel II is fixedly sleeved on the outer wall of the driving rod. A transmission belt II for transmission cooperation is arranged outside the transmission wheels II and III. By operating the driving mechanism, the pressing plate can be driven to perform vertical displacement, and the closing column can be driven to perform horizontal displacement.

[0010] As a further improvement of the above solution, a driving sleeve fixedly sleeved on the outer wall of the driving shaft is arranged inside the transmission wheel II. A plurality of mounting blocks are fixed on the outer side of one end of the driving sleeve. A clamping block hinged to the driving sleeve is arranged inside the mounting block. A clamping groove for clamping and cooperating with the clamping block is formed on the inner wall of the transmission wheel II. A plurality of connecting springs for pulling and deflecting the deflected clamping block to reset are fixed between the mounting block and the clamping block.

[0011] As a further improvement of the above solution, a connecting component for connecting the transmission wheel II is arranged on the driving sleeve. The connecting component includes an annular groove formed on the driving sleeve and a connecting plate slidably inserted inside the annular groove. The connecting plate is fixed to the transmission wheel II. By the cooperative work of the connecting plate and the annular groove, the transmission wheel II can be restricted outside the driving sleeve to prevent the driving sleeve from separating from the transmission wheel II.

[0012] As a further improvement of the above solution, the housing is provided with an infusion assembly for injecting liquid into the purification chamber. The infusion assembly includes a liquid inlet groove formed on the inner wall between the water storage chamber and the purification chamber. A plugging block for closing the liquid inlet groove is arranged inside the liquid inlet groove. A transmission block fixed on the plugging block is arranged in the water storage chamber. An outer part of the transmission block is movably sleeved with a push plate that slides inside the water storage chamber for pushing the liquid. A filter screen for filtering the liquid is arranged between the push plate and the plugging block. The filter screen is movably sleeved on the outer part of the transmission block. A plurality of linkage blocks fixed on the transmission block for pushing the transmission block to displace are arranged between the push plate and the filter screen. Through the operation of the infusion assembly, the liquid in the water storage chamber can be pushed through the liquid inlet groove into the purification chamber. The amount of the liquid injected into the purification chamber can be controlled by the displacement distance of the push plate.

[0013] As a further improvement of the above solution, the filter screen is fixed inside the water storage chamber and is located between the liquid level valve and the plugging block. Blocking blocks for preventing the plugging block from sliding into the water storage chamber are arranged at two ends of one side of the plugging block close to the transmission block and are fixed inside the liquid inlet groove. Through the filter screen, the liquid injected into the purification chamber can be filtered. Through the blocking blocks, the plugging block can be prevented from entering the water storage chamber.

[0014] As a further improvement of the above solution, a receiving groove is formed at one end of the transmission block away from the plugging block. A loading block fixed on the inner wall of the water storage chamber is slidably inserted into the receiving groove. A limiting block that slides inside the receiving groove is fixed at the end of the loading block located inside the receiving groove. A plurality of return springs for pulling the transmission block to displace for resetting are fixed between the limiting block and the inner wall of the end of the receiving groove. Through the elasticity of the return springs, the transmission block can be pulled to displace for resetting.

[0015] As a further improvement of the above solution, a screw rod for driving the push plate to displace is threadedly inserted through the push plate. One end of the screw rod is drivingly connected to a motor I fixed on the inner wall of the water storage chamber. The other end of the screw rod penetrates through the filter screen and is rotatably connected to the inner wall of the water storage chamber. A cleaning brush with bristles contacting the filter screen is fixed on the outer wall of the screw rod. Through the operation of the motor I, the screw rod can be driven to rotate, driving the push plate to displace. When the screw rod is driven to rotate, the cleaning brush will be driven to rotate. The filter screen can be cleaned by the rotating cleaning brush to prevent the filter holes of the filter screen from being blocked after a long time of cleaning work.

[0016] As a further improvement of the above solution, the end of the drive shaft away from the drive plate II is rotatably connected to a fixing plate fixed on the housing. One end of the drive rod is drivingly connected to a motor II. The motor II is fixed on the fixing plate located at one end of the push plate. The other end of the drive rod is rotatably connected to the fixing plate located at the other end of the push plate. Through the operation of the motor II, the drive rod can be driven to rotate.

Specific implementation mode

[0032] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0033] Embodiment 1:

[0034] Combined with Figure 1 、 Figure 2 and Figure 3 , the secondary dust removal cover of the horizontal cement silo in this embodiment includes a cover body 1, a shell 2 provided on one side of the cover body 1, and a water storage cavity 5 and a purification cavity 6 opened in the shell 2. The purification mechanism includes an air inlet hole 38 opened on the outside of the cover body 1 for sucking air, a fan 3 provided on the top side of the cover body 1, and a water liquid provided inside the purification cavity 6 for dust removal and purification of air. The input end of the fan 3 is connected with an air inlet pipe 4 communicated with the cover body 1, and the output end of the fan 3 is connected with an air outlet pipe 8 whose tail end extends into the water liquid inside the purification cavity 6. An air outlet hole 7 for discharging the gas inside the purification cavity 6 is opened on the cover body 1;

[0035] The drainage mechanism includes a pressing plate 9 slid in the purification cavity 6 for pressing the water liquid and a drainage hole opened on the cover body 1 for discharging the water liquid inside the purification cavity 6. A sealing column 11 for closing the drainage hole is slidably connected inside the drainage hole. The shell 2 is provided with a driving mechanism for driving the pressing plate 9 and the sealing column 11 to displace.

[0036] In the embodiment of the present application, the implementation principle of the horizontal cement silo secondary dust removal cover is as follows: When it is necessary to process the dust overflowing from the gaps of the cloth bags, the cover body 1 is placed outside the gaps of the cloth bags. Through the operation of the fan 3, the air in the cover body 1 is drawn by the intake pipe 4. As the air in the cover body 1 is drawn, the external dust will enter the interior of the cover body 1 through the intake holes 38 on the cover body 1, and then enter the interior of the intake pipe 4 mixed with the air and be transported to the interior of the outlet pipe 8. At this time, the dust entering the interior of the outlet pipe 8 will enter the water liquid in the purification chamber 6. At this time, the water liquid in the purification chamber 6 can be used to perform secondary dust removal and purification on the airflow mixed with dust. When the water liquid in the purification chamber 6 has undergone a period of purification work and there are a large number of dust impurities mixed in the water liquid and it is necessary to replace the water liquid, a corresponding water receiving device can be placed below the drain hole. By the displacement of the sealing column 11, the drain hole is opened. At this time, the water liquid in the purification chamber 6 can be discharged through the drain hole. At the same time, by the vertical downward displacement of the pressing plate 9, the water liquid in the purification chamber 6 is pressed, forcing the water liquid in the purification chamber 6 to pass through the drain hole and improving the drainage rate of the drain hole. When the water liquid in the purification chamber 6 is drained completely, the drain hole is sealed by the displacement of the sealing column 11. And when the sealing column 11 is displaced, the drain hole will be cleaned and dredged to prevent the drain hole from being blocked by the impurities in the water liquid during the drainage process.

[0037] The interior of the water storage chamber 5 stores water liquid. A liquid level valve for injecting water liquid into the water storage chamber 5 is installed at the top of the housing 2. Through the liquid level valve, an appropriate amount of water liquid can be injected into the water storage chamber 5.

[0038] Embodiment 2:

[0039] Combined with Figure 4 、 Figure 5 and Figure 9, on the basis of Embodiment 1, the further improvement of this embodiment lies in that: the driving mechanism includes a lead screw 12 threadedly passing through both ends of the pressing plate 9 for driving the pressing plate 9 to perform vertical displacement, and a push plate 10 arranged at one end of the housing 2 for driving the closing column 11 to perform horizontal displacement. The end of the closing column 11 located outside the housing 2 is fixed on the push plate 10. A driving rod 13 is provided on the side of the push plate 10 away from the housing 2. Transmission wheels one are arranged on the outer walls of the tops of the lead screw 12 and the driving rod 13, and a transmission belt one for transmission cooperation is arranged outside the transmission wheels one. Fixing blocks are fixed at both ends of the side of the push plate 10 close to the driving rod 13. A driving plate one 16 is hinged to the outside of the fixing block. The movable end of the driving plate one 16 is hinged to a driving plate two 15. A driving shaft 14 is fixed at the movable end of the driving plate two 15. A transmission wheel two 22 is arranged outside the driving shaft 14. A transmission wheel three corresponding to the transmission wheel two 22 is fixedly sleeved on the outer wall of the driving rod 13. A transmission belt two for transmission cooperation is arranged outside the transmission wheel two 22 and the transmission wheel three. A driving sleeve 17 fixedly sleeved on the outer wall of the driving shaft 14 is arranged inside the transmission wheel two 22. A plurality of mounting blocks 18 are fixed on the outside of one end of the driving sleeve 17. A clamping block 19 hinged to the driving sleeve 17 is arranged inside the mounting block 18. A clamping groove 20 for clamping and cooperating with the clamping block 19 is formed on the inner wall of the transmission wheel two 22. A plurality of connecting springs 21 for pulling and deflecting the deflecting clamping block 19 to reset are fixed between the mounting block 18 and the clamping block 19. By the clockwise rotation of the driving rod 13, through the transmission cooperation of the transmission wheel two 22, the transmission wheel three and the transmission belt two, the transmission wheel two 22 is driven to rotate. Through the cooperation of the clamping block 19, the clamping groove 20 and the mounting block 18, the driving sleeve 17 and the driving shaft 14 are driven to rotate. At this time, the rotating driving shaft 14 will drive the driving plate two 15 and the driving plate one 16 to deflect, drive the push plate 10 and the fixing block to perform reciprocating displacement, drive the closing column 11 to perform reciprocating displacement. When the displaced closing column 11 opens the drain hole, the water liquid can be discharged through the drain hole at this time. When the driving rod 13 rotates clockwise, through the cooperation of the transmission wheel one and the transmission belt one, the lead screw 12 will be driven to rotate, driving the pressing plate 9 to perform vertical upward displacement. When the drain hole is opened, by the counterclockwise rotation of the driving rod 13, through the transmission cooperation of the transmission wheel two 22, the transmission wheel three and the transmission belt two, the transmission wheel two 22 is driven to rotate. Through the cooperation of the clamping block 19, the clamping groove 20 and the mounting block 18, at this time the driving sleeve 17 and the driving shaft 14 will not rotate, and the closing column 11 remains in place. When the driving rod 13 rotates counterclockwise, through the cooperation of the transmission wheel one and the transmission belt one, the lead screw 12 will be driven to rotate, driving the pressing plate 9 to perform vertical downward displacement, pressing the water liquid inside the purification chamber 6, forcing the water liquid inside the purification chamber 6 to pass through the drain hole.

[0040] Embodiment 3:

[0041] Combined with Figure 10, on the basis of Embodiment 2, a further improvement in this embodiment is that: the driving sleeve 17 is provided with a connecting component for connecting the second transmission wheel 22. The connecting component includes an annular groove 24 opened on the driving sleeve 17 and a connecting plate 23 slidably inserted into the annular groove 24. The connecting plate 23 is fixed on the second transmission wheel 22. Through the cooperation of the connecting plate 23 and the annular groove 24, the second transmission wheel 22 can be restricted outside the driving sleeve 17 to prevent the driving sleeve 17 from separating from the second transmission wheel 22.

[0042] Embodiment 4:

[0043] Combined with Figure 6 and Figure 7 , on the basis of Embodiment 1, a further improvement in this embodiment is that: the housing 2 is provided with an infusion component for injecting liquid into the purification chamber 6. The infusion component includes a liquid inlet groove 26 opened on the inner wall between the water storage chamber 5 and the purification chamber 6. A blocking block 27 for closing the liquid inlet groove 26 is arranged inside the liquid inlet groove 26.

A filter screen 30 for filtering the liquid is arranged between the push plate 31 and the blocking block 27. The filter screen 30 is movably sleeved outside the transmission block 29. A plurality of linkage blocks 33 fixed on the transmission block 29 for pushing the transmission block 29 to displace are arranged between the push plate 31 and the filter screen 30. When it is necessary to inject liquid into the purification chamber 6, the push plate 31 displaces. When the displaced push plate 31 contacts the linkage block 33, at this time, the displaced push plate 31 can push the linkage block 33 and the transmission block 29 to displace, driving the blocking block 27 to displace. When the displaced blocking block 27 opens the liquid inlet groove 26, at this time, the liquid in the water storage chamber 5 can be pushed by the continuously displaced push plate 31 to enter the purification chamber 6 through the liquid inlet groove 26. At this time, a sufficient amount of liquid can be injected into the purification chamber 6, and the amount of the liquid injected into the purification chamber 6 can be controlled by the displacement distance of the push plate 31.

[0044] The filter screen 30 is fixed inside the water storage chamber 5. The filter screen 30 is located between the liquid level valve and the blocking block 27. Two ends of the side of the blocking block 27 close to the transmission block 29 are provided with blocking blocks 28 fixed inside the liquid inlet groove 26 for preventing the blocking block 27 from sliding into the water storage chamber 5. Through the filter screen 30, the liquid injected into the purification chamber 6 can be filtered.

A plurality of return springs 37 for pulling the displacement transmission block 29 to perform a reset displacement are fixed between the limiting block 35 and the inner wall of the end of the receiving groove 34. When it is not necessary to inject liquid into the purification cavity 6, the push plate 31 performs a reset displacement. When the displaced push plate 31 is separated from the linkage block 33, due to the elasticity of the return spring 37, the transmission block 29 is pulled to perform a reset displacement, driving the plugging block 27 to perform a reset displacement, driving the plugging block 27 to close the liquid inlet groove 26. At this time, the liquid in the water storage cavity 5 will not enter the purification cavity 6.
