[0031] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0032] This application discloses a cement pneumatic conveying device. (Refer to...) Figure 1 and Figure 2 A cement pneumatic conveying device includes a storage cylinder 1, which is mounted on the ground by bolts and a fixing base. An air inlet pipe 101 is fixedly connected to the left side of the storage cylinder 1, and a discharge pipe 102 is fixedly connected to the right side of the storage cylinder 1. A blower 3 is fixedly connected to the end of the air inlet pipe 101 furthest from the storage cylinder 1. A conveying mechanism 2 is arranged above the storage cylinder 1. The conveying mechanism 2 includes a connecting pipe 201, one end of which is connected to the top wall of the storage cylinder 1. A suction fan 202 is installed at the top of the connecting pipe 201, and a bend pipe 203 is fixedly connected to the rear end of the connecting pipe 201. A telescopic pipe 204 is fixedly connected to the bottom end of the bend pipe 203, and a suction port 205 is fixedly connected to the bottom end of the telescopic pipe 204.

[0033] Reference Figure 1 and Figure 2 A fixing seat 4 is fixedly connected to the outer surface of the connecting pipe 201. The bottom surface of the fixing seat 4 is fixedly connected to the upper surface of the storage cylinder 1. The fixing seat 4 can reinforce the connecting pipe 201 and improve its stability. Control handles 5 are provided on both the left and right sides of the suction port 205. The ends of the two control handles 5 that are close to each other are fixedly connected to the left and right sides of the suction port 205 respectively. By providing control handles 5, the suction port 205 can be pulled, making it easy for the suction port 205 to move downwards.

[0034] During use, the transport machinery is moved below the suction port 205, and the operator pulls the control handle 5 to extend the telescopic pipe 204, bringing the suction port 205 into contact with the cement. The suction fan 202 is then activated, drawing air from inside the bend 203, reducing the internal air pressure and allowing the suction port 205 to draw in the cement. The cement passes through the bend 203 and connecting pipe 201 into the storage tank 1. The blower 3 is then activated, blowing air through the air inlet pipe 101, agitating the falling cement and guiding it into the discharge pipe 102. This process reduces the risk of large-scale cement spillage during transfer and delivery, improving safety.

[0035] Reference Figure 3 and Figure 4 A sealing plate 208 is fixedly connected to the inner wall of the storage cylinder 1, and a conical cover 207 is fixedly connected to the inner top wall of the storage cylinder 1. The bottom end of the conical cover 207 passes through the sealing plate 208 and communicates with the discharge pipe 102. Two support rods 8 are fixedly connected to the outer surface of the conical cover 207. The end of each support rod 8 away from the conical cover 207 is fixedly connected to the inner wall of the storage cylinder 1. The support rods 8 can support the conical cover 207 and increase its stability. Two fixing plates 6 are fixedly connected to the bottom surface of the sealing plate 208. The sides of the two fixing plates 6 that are away from each other are fixedly connected to the inner side wall of the storage cylinder 1. The fixing plates 6 can reinforce the sealing plate 208 and prevent it from falling off. Two flow guides 7 are fixedly connected to the inner wall of the storage cylinder 1. The ends of the two flow guides 7 that are far apart from each other are fixedly connected to the ends of the air inlet pipe 101 and the discharge pipe 102 that are close to each other. The flow guides 7 can facilitate the guidance of cement and reduce the cement residue inside the storage cylinder 1.

[0036] A motor 211 is fixedly connected to the inner top wall of the storage cylinder 1, and a screw conveyor shaft 206 is fixedly connected to the output end of the motor 211. A protective shell 9 is rotatably connected to the outer surface of the screw conveyor shaft 206 through a bearing. The upper surface of the protective shell 9 is fixedly connected to the inner top wall of the storage cylinder 1. The protective shell 9 can protect the motor 211 and prevent the motor 211 from being interfered with.

[0037] Reference Figure 4 The bottom end of the connecting pipe 201 is rotatably connected to a sealing cap 209 via a reset shaft, and a dustproof net 210 is fixedly connected to the inner wall of the connecting pipe 201. The dustproof net 210 is located below the suction fan 202 and above the bend 203. The dustproof net 210 can block cement and prevent cement from entering the suction fan 202.

[0038] After the cement is pumped into the connecting pipe 201, it falls onto the sealing cover 209 under gravity. When the weight of the cement exceeds the load of the sealing cover 209, the sealing cover 209 opens, allowing the cement to enter the conical cover 207. Then, the sealing cover 209 is reset by the reset pin, sealing the bottom of the connecting pipe 201. Then, the motor 211 is started, causing the screw conveyor shaft 206 to transport the cement to the area below the sealing plate 208.

[0039] The implementation principle of a cement pneumatic conveying device according to this application embodiment is as follows: During use, the conveying machinery is moved below the suction port 205. Then, the operator pulls the control handle 5 to extend the telescopic pipe 204, bringing the suction port 205 into contact with the cement. The suction fan 202 is started, drawing gas from the inside of the bend pipe 203, reducing the internal air pressure and forcing cement to enter the bend pipe 203 from the suction port 205. At this time, the dustproof net 210 intercepts the cement, preventing it from entering the suction fan 202. Under gravity, the cement falls onto the sealing cover 209. When the weight of the cement exceeds the load of the sealing cover 209, the sealing cover 209 opens, allowing the cement to enter the conical shroud 207. Immediately afterwards, the sealing cover 209 resets via the reset pin, sealing the bottom of the connecting pipe 201. The motor 211 is started, causing the screw conveyor shaft 206 to transport cement to below the sealing plate 208; simultaneously, the blower 3 is started, blowing air into the air inlet pipe 101, causing the air to agitate the falling cement, which then enters the discharge pipe 102, and is subsequently blown to the designated location by the air pressure through the discharge pipe 102. This reduces the occurrence of large amounts of cement spillage during the transfer and delivery process, reduces pollution, and improves safety.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
