Description

Technical Field

[0001] The invention belongs to the technical field of material conveying, and in particular relates to a feeding device for cement packaging. Background Art

[0002] Cement is a hydraulic cementitious material, mainly made of limestone, clay, iron ore and other raw materials, which are ground after high-temperature calcination. The core components are tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium aluminoferrite. It undergoes hydration reaction when it comes into contact with water to form hard hydrated calcium silicate gel, which can firmly bond sand and gravel aggregates to form concrete. As a core material for modern infrastructure, it is widely used in buildings, roads, bridges and water conservancy projects.

[0003] Cement is usually stored in a concrete silo, which is equipped with a unloading decompression cone chamber and an aeration device. The air source is provided by a Roots blower, and aeration and mixing are performed to achieve homogenization to ensure uniform cement composition.

[0004] Before packaging, the conveyor belt, vibrating screen and other equipment may cause rigid structures to form between cement particles due to vibration or extrusion, causing agglomeration. The agglomerated cement will clog the feeding port of the packaging machine, resulting in slower bagging speed and even frequent shutdowns for cleaning, which will reduce production efficiency. In addition, agglomerated cement may puncture the packaging bag due to stress concentration between particles during transportation, causing ash leakage or pollution, and increasing the scrap rate. Cement is easily affected by moisture when stored for a long time, and a key drying step is often missing, which makes it easier for cement to absorb moisture in the air during storage and transportation, leading to problems such as agglomeration and reduced strength.

[0018] The beneficial effects of a feeding device for cement packaging provided by this scheme are as follows: (1)Set up a fluidized conveying device to dry cement using the fluidization principle. Under the fluidized state, cement particles are suspended and dispersed, forming a gas-solid two-phase (gas and solid) mixing layer, which increases the surface area compared to traditional static drying, significantly accelerating the heat and mass transfer rate, achieving the drying of cement powder. Moreover, the shear force of the air flow can break the van der Waals force between particles, reducing the agglomeration phenomenon and avoiding the blockage problem caused by caking after packaging. (2)Recover wind energy. Use the energy of the heated air to drive the transmission impeller to rotate. Through the transmission impeller, drive the vibration connecting rod and the hammer to rotate. The vibration generated by the hammer hitting the vibration ring can make the caked cement collide with the filter chamber, avoiding the blockage of the filter chamber while also breaking the caked cement. (3)Set up a feeding device. Use the transmission of the grooved wheel and the dial to drive the separation runner to rotate at a fixed angle, enabling the cement powder in the storage bin to pass through the feeding bin quantitatively, achieving the technical effect of quantitative feeding.

[0026] During specific use, first add the cement raw materials into the fluidized conveying device 1, and place the cement raw materials into the feeding hopper 124. At the same time, start the feeding motor 123. The feeding motor 123 drives the feeding auger 122 to rotate, and the feeding auger 122 is used to lift the cement raw materials in the feeding hopper 124 into the filling channel 121. The cement raw materials enter the fluidization chamber 101 through the filling channel 121, and then the cement raw materials fall into the filtration chamber 108. The caked cement in the cement raw materials will remain in the filtration chamber 108, and the cement powder will fall onto the air-permeable plate 107 through the filtration chamber 108. At the same time, start the conveying fan 125 and the heating plate 126. The conveying fan 125 sucks air into the heating plate 126, and the air is heated by the heating plate 126 and then enters the fluidization chamber 101 through the air inlet channel 103. Then the air passes through the air-permeable plate 107 and pushes up the sealing valve plate 113 on the air-permeable plate 107. Due to the fluidization principle (a physical phenomenon in which solid particles exhibit fluid-like characteristics under the action of a fluid), the air passing through the cement powder on the air-permeable plate 107 becomes a boiling state. At the same time, the hot air can break up the lumps formed by vibration or extrusion between the cement particles and restore the powder to a loose state. During the fluidization process, the particles are in full contact with the hot air, the adsorbed moisture or static electricity on the surface is reduced, and the fluidity is enhanced. The cement powder passes through the air-permeable plate 107 and falls to the bottom of the fluidization chamber 101. Start the recovery motor 106, and the recovery motor 106 drives the recovery auger 105 to rotate. The cement powder is sent out of the fluidization chamber 101 through the recovery auger 105. Since the filling channel 121 is filled with cement raw materials, the air will not leak from the filling channel 121. The air in the fluidization chamber 101 is discharged from the exhaust channel 104 through the dust removal bag 111. The dust removal bag 111 can filter the cement dust and reduce the dust during the feeding process. When the air flow passes through the exhaust channel 104, it will drive the transmission impeller 112 to rotate. The rotation of the transmission impeller 112 drives the transmission connecting rod 110 to rotate. The rotation of the transmission connecting rod 110 drives the vibration connecting rod 120 to rotate. The rotation of the vibration connecting rod 120 drives the carrying ring 117 to rotate. The rotation of the carrying ring 117 drives the hammer 118 to rotate. Since the hammer 118 is pulled by the tension spring 119, the upper end of the hammer 118 will closely adhere to the hammering wedge surface 116. As the hammer 118 rotates with the carrying ring 117, the hammer 118 will be pushed outward by the hammering wedge surface 116. Then, the hammer 118 and the hammering wedge surface 116 will strike the vibration ring 115, and the kinetic energy generated by striking the vibration ring 115 is transmitted to the filtration chamber 108. The caked cement in the filtration chamber 108 collides with the filtration chamber 108 and is broken into powder, and the cement that has become powder continues to be dried in a fluidized state.After the crushed cement powder is discharged from the fluidization chamber 101, it is sent into the transfer hopper 201. The transfer motor 203 is started, and the transfer motor 203 drives the transfer auger 202 to rotate. The rotation of the transfer auger 202 sends the cement powder in the transfer hopper 201 into the storage bin 204. The separation motor 210 is started, and the separation motor 210 drives the dial 209 to rotate. The rotation of the dial 209 drives the sprocket 208 to rotate. The groove angle of the sprocket 208 is 90 degrees. Therefore, when the dial 209 rotates one circle, it drives the sprocket 208 to rotate 90 degrees. The rotation of the sprocket 208 drives the separation runner 207 to rotate. The cement powder in the storage bin 204 falls into the separation runner 207. After that, the separation runner 207 continues to rotate 180 degrees, and the cement powder in the separation runner 207 can be conveyed to the feeding chamber 206. Subsequently, the bottom of the feeding chamber 206 can be connected to the packing equipment for packing.
