Specific embodiments
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0027] Referring to Figures 1-5 , a cement silo for cement processing includes a storage box 2. A feed pipe 7 is installed at the top of the storage box 2, and a number of hoppers 17 are installed at the bottom of the storage box 2. The bottoms of the hoppers 17 are all connected by a screw feeder 18. A support frame 1 is installed at the bottom edge of the storage box 2, and the bottom of the support frame 1 extends below the screw feeder 18. During actual use, the staff can connect the feed pipe 7 to an external conveying pipeline, and convey cement from the feed pipe 7 into the storage box 2 for storage. When discharging is required, the screw feeder 18 can discharge the cement in the storage box 2.
[0028] It should be noted that after conveying cement into the storage box 2, the top of the feed pipe 7 can be sealed with a sealing cover to prevent rainwater from flowing into the storage box 2.
[0029] As Figure 1 and Figure 2 shown, two installation boxes 4 are symmetrically installed at the top of the storage box 2. A screw rod 22 is rotatably connected inside each installation box 4, and one end of each screw rod 22 is connected to a drive motor 13. The drive motors 13 are all fixed on the side walls of the corresponding installation boxes 4. A connecting block 8 is sleeved on each screw rod 22. Through grooves 21 are symmetrically opened at the top of the storage box 2. The bottom of the connecting block 8 penetrates through the through groove 21 and extends into the storage box 2. During actual use, the drive motor 13 can drive the screw rod 22 to rotate, so that the connecting block 8 can move along the through groove 21.
[0030] As Figure 2 and Figure 3 shown, a strip-shaped connecting plate 20 is installed at the bottom of each connecting block 8, and both ends of each strip-shaped connecting plate 20 are connected by a push plate 19. During actual use, the push plate 19 can be driven to horizontally move inside the storage box 2 through the connecting block 8. In this way, when conveying cement into the storage box 2, the push plate 19 will scrape the top of the cement flat, so that the cement is evenly piled up inside the storage box 2, and the cement will not be centrally piled up under the feed pipe 7.
[0031] As Figure 1 shown, a top cover 12 is installed on the top of each installation box 4, and one end of the top ends of the two top covers 12 is connected by a diversion pipe 11. An air inlet pipe 15 is installed on the side of the diversion pipe 11. A collection box 23 is installed on the top of the storage box 2. A cover plate 16 is installed on the top of the collection box 23. The other end of the air inlet pipe 15 is fixed to one end of the cover plate 16 and is communicated with the inside of the collection box 23. The other end of the top of the cover plate 16 is installed with an air suction pipe 10. The other end of the air suction pipe 10 is connected to the air inlet end of the air delivery pump 9, and the air delivery pump 9 is fixed on the top of the storage box 2. During actual use, after the cement is conveyed into the storage box 2, the air delivery pump 9 can be controlled to work. The air delivery pump 9 sucks out the gas in the collection box 23 through the air suction pipe 10, so that a negative pressure is generated in the collection box 23, and the air inlet pipe 15 and the diversion pipe 11 will generate suction force to adsorb the cement dust floating in the storage box 2 into the collection box 23. In this way, when the conveying pipeline is disassembled from the feed pipe 7, the cement dust will not float into the external environment.
[0032] As Figure 4 shown, a baffle 6 is installed inside the collection box 23. A frame 3 is installed on the top of the baffle 6. A first filter screen 24 is installed inside the frame 3. Under the action of the first filter screen 24, the cement dust sucked into the collection box 23 can be filtered to prevent the cement dust from being discharged into the external environment by the air delivery pump 9.
[0033] It should be noted that the edges of the frame 3 are hermetically fitted with the inner wall of the collection box 23, the top of the baffle 6, and the bottom of the cover plate 16 respectively. During actual use, the cement dust sucked into the collection box 23 by the air inlet pipe 15 will not leak from the gap at the edge of the frame 3 to the other end of the collection box 23, improving the filtering effect.
[0034] It should be noted that the first filter screen 24 is located between the air suction pipe 10 and the air inlet pipe 15. In this way, the cement dust conveyed into the collection box 23 by the air inlet pipe 15 will move towards the first filter screen 24 under the action of the air suction pipe 10. The cement dust in the air is filtered by the first filter screen 24, and the pure air passes through the first filter screen 24 and is adsorbed by the air suction pipe 10 and finally discharged through the air outlet end of the air delivery pump 9.
[0035] Specifically, when the utility model is feeding materials, the staff connects the external conveying pipeline to the feed pipe 7, and conveys cement into the storage tank 2 through the feed pipe 7. During the conveying process, the staff controls the driving motor 13 to work. The driving motor 13 drives the screw rod 22 to rotate, and the connecting block 8 moves horizontally along the screw rod 22, so that the pushing plate 19 moves horizontally inside the storage tank 2. When the pushing plate 19 moves to a preset position at one end inside the storage tank 2, the driving motor 13 reverses, the screw rod 22 reverses, and the connecting block 8 and the pushing plate 19 move in the opposite direction. This will cause the pushing plate 19 to move horizontally back and forth in the storage tank 2, flattening the top of the cement, so that the cement can be fully stored in the storage tank 2. When the cement conveying is completed, the staff controls the air delivery pump 9 to work. The air delivery pump 9 sucks out the air in the collection box 23 through the suction pipe 10, creating a negative pressure in the collection box 23. The intake pipe 15 and the diversion pipe 11 generate suction, sucking the cement dust floating in the storage tank 2 into the collection box 23 through the through slot 21 and filtering it through the first filter screen 24. After being filtered by the first filter screen 24, the cement dust falls into the collection box 14, and the remaining clean air passes through the first filter screen 24 and is adsorbed by the suction pipe 10, and finally discharged from the air outlet end of the air delivery pump 9.
[0036] Furthermore, as Figure 3 shown, dust-proof covers 5 are installed on both top sides of the connecting block 8. The dust-proof covers 5 are sleeved on the surface of the screw rod 22, and the other ends of the dust-proof covers 5 are fixed on the side walls of the installation box 4. The dust-proof covers 5 are flexible corrugated covers, and there is a gap between the inner surface of the dust-proof covers 5 and the side surface of the screw rod 22. During actual use, the dust-proof covers 5 can cover the screw rod 22, preventing cement dust from adhering to the screw rod 22 and accelerating the wear of the screw rod 22. And since the dust-proof covers 5 can contract as the connecting block 8 moves, it will not interfere with the movement of the connecting block 8 along the screw rod 22.
[0037] Furthermore, as Figure 4 shown, an opening is provided at one end of the collection box 14 close to the intake pipe 15. A collection box 14 is provided at one end inside the collection box 14 close to this opening. One end of the collection box 14 extends out of the opening, and the outer surface of the collection box 14 is in sealed cooperation with the inner wall of the collection box 23. During actual use, the collection box 14 can collect the cement dust filtered by the first filter screen 24, which is convenient for taking out and processing.
[0038] Furthermore, as Figure 1 and Figure 5As shown in the figure, a pressure relief pipe 25 is installed at one end of the top of the storage box 2. A second filter screen 26 is installed inside the pressure relief pipe 25, and the top opening of the pressure relief pipe 25 is connected with a sealing cover 27. When transporting cement into the storage box 2, the staff opens the sealing cover 27, and the excess air in the storage box 2 is discharged through the pressure relief pipe 25. Under the action of the second filter screen 26, the cement dust can be filtered out to prevent the cement dust from spreading into the external environment. Moreover, after the cement transportation is completed, when the air delivery pump 9 works to remove the cement dust floating inside the storage box 2, the external air can be transported into the storage box 2 through the pressure relief pipe 25, so that the air pressure inside the storage box 2 remains balanced. Also, when not in use, the sealing cover 27 can be covered on the top of the pressure relief pipe 25, so that rainwater will not flow into the storage box 2 from the pressure relief pipe 25.
[0039] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
