Description

Technical Field

[0001] This utility model relates to the technical field of cement silo bottom blockage cleaning equipment, and in particular to a silo bottom lifting and material-pumping device. Background Technology

[0002] Cement clumping at the bottom of cement silos is a common problem during cement production and storage. Cement itself has a certain degree of water absorption; if the moisture-proofing measures at the bottom of the silo are inadequate, moisture from the surrounding environment will be absorbed by the cement particles. When the absorbed moisture reaches a certain level, the mineral components in the cement (such as tricalcium silicate and dicalcium silicate) will undergo hydration reactions. For example, tricalcium silicate reacts with water to form hydrated calcium silicate gel and calcium hydroxide. These hydration products bind the cement particles together, gradually forming clumps. Even in relatively dry environments, cement stored at the bottom of silos for extended periods will still agglomerate over time due to electrostatic adsorption between the cement particles. Furthermore, cement particles, under long-term accumulation, are subjected to pressure from their own weight. The cement at the bottom experiences greater pressure, gradually reducing the distance between particles and increasing the chances of contact and bonding, thus making clumping more likely.

[0003] The current method for cleaning cement lumps at the bottom of cement silos is manual. Workers, wearing personal protective equipment, enter the silo and use tools such as steel bars, pneumatic picks, hammers, and shovels to break up and remove the lumps. For example, smaller lumps can be broken up with steel bars or hammers; larger, harder lumps are loosened with pneumatic picks and broken into smaller pieces for easier removal. This method is labor-intensive and relatively inefficient. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a silo bottom lifting and material feeding device.

[0005] This utility model is implemented as follows: a silo bottom lifting and material-push device includes a first valve located at the outlet of the cement silo, a second valve located below the first valve, a material outlet located above the second valve, and a lifting and material-push mechanism located below the second valve.

[0006] The lifting and feeding mechanism includes a frame located below the second valve, a lifting rod inside the frame, a feeding component at the upper end of the lifting rod, and a lift mechanism for driving the lifting rod to move up and down.

[0007] The frame is equipped with a lifting platform via a mounting base.

[0008] The frame is equipped with a storage bin.

[0009] The lifting rod passes through the bottom of the storage box.

[0010] The storage box has a discharge port on one side, and a discharge gate is provided on the discharge port.

[0011] Both the first valve and the second valve are slide gate valves.

[0012] The material-carrying component consists of several blades located at the end of the lifting rod.

[0013] The second valve is tilted. When closed, the tilted slide of the second valve acts as a guide, facilitating the discharge of materials from the outlet.

[0014] The bottom of the storage box is inclined.

[0015] The discharge port is located on the side.

[0016] The lifting rod has a hollow structure with internal threads that engage with the lead screw of the lifting machine. A guide rod is provided on the lifting rod, and a track is provided on the frame to engage with the guide rod to prevent the lifting rod from rotating. The rotation of the lead screw drives the lifting rod to move up and down.

[0017] A nut can be installed at the lower part of the lifting rod to replace the internal thread inside the lifting rod.

[0018] Over time, the discharge port at the bottom of the finished cement silo is prone to accumulating hardened lumps of material, which affects material discharge and causes blockages. When a blockage occurs, open the first and second valves, start the elevator to move the lifting rod upward to pry open the lumpy accumulation area. The pried-open material falls under the frame, where a storage box is installed to collect the fallen material. Opening the discharge door of the storage box facilitates the discharge of material. The bottom of the storage box is inclined to guide the flow and facilitate the discharge of material from the storage box. Attached Figure Description

[0026] The difference between Example 2 and Example 1 is that the lifting and feeding mechanism includes a frame 1 set under the second valve 4, a lifting rod 6 is provided in the frame 10, a feeding component 7 is provided at the upper end of the lifting rod 6, and a lifting machine 9 is provided in the frame 10 to drive the lifting rod 6 to move up and down.

[0027] The difference between Example 3 and Example 2 is that the frame 10 is equipped with the elevator 9 via the mounting base 11.

[0028] The difference between Example 4 and Example 3 is that the frame 10 is provided with a storage box 8.

[0029] The difference between Example 5 and Example 4 is that the lifting rod 6 passes through the bottom of the storage box 8.

[0030] The storage box 8 has a discharge port 5 on one side, and a discharge gate is provided on the discharge port.

[0031] Both the first valve 2 and the second valve 4 are slide gate valves.

[0032] The difference between Example 6 and Example 5 is that the material feeding component 7 is a plurality of blades 12 disposed at the end of the lifting rod 6.

[0033] The difference between Example 7 and Example 6 is that the second valve is tilted. When closed, the tilted slide of the second valve plays a guiding role, which facilitates the discharge of materials in the silo from the outlet.

[0034] The difference between Example 8 and Example 7 is that the bottom of the storage box 8 is inclined.

[0035] The discharge port 3 is located on the side.

[0036] The lifting rod 6 has a hollow structure and an internal thread inside. The internal thread cooperates with the lead screw 13 of the lifting machine 9. The lifting rod 6 is provided with a guide rod 14, and the frame 10 is provided with a track 15 that cooperates with the guide rod 14 to prevent the lifting rod 6 from rotating. The rotation of the lead screw 13 drives the lifting rod 6 to move up and down.

[0037] A nut can be installed at the lower part of the lifting rod to replace the internal thread inside the lifting rod.

[0038] Over time, the discharge port at the bottom of the finished cement silo is prone to accumulating hardened lumps of material, which affects material discharge and causes blockages. When a blockage occurs, open the first and second valves, start the elevator to move the lifting rod upward to pry open the lumpy accumulation area. The pried-open material falls under the frame, where a storage box is installed to collect the fallen material. Opening the discharge door of the storage box facilitates the discharge of material. The bottom of the storage box is inclined to guide the flow and facilitate the discharge of material from the storage box.
