Description

Technical Field

[0001] This utility model relates to the technical field of cement storage device for preventing caking, and more particularly to a cement storage device for preventing caking. Background Technology

[0002] Cement is a powdered hydraulic inorganic binder widely used in construction, roads, bridges, tunnels, and other engineering projects, and is an indispensable material in modern civil engineering. Its main function is as a binder, binding aggregates such as sand and stone together to form concrete structures with a certain strength and durability. After being produced in the factory, cement is usually packaged in woven bags for easy transportation from the factory to transfer stations or users. Currently, bagged cement is generally stored on the ground, which easily absorbs moisture from the air, causing a hydration reaction that leads to clumping, hardening, and cement waste.

[0003] Chinese patent publication number CN213036536U discloses a storage device for preventing cement from clumping. The device includes a storage box with a base plate fixedly connected to its bottom. A suction fan is fixedly connected to the top of the base plate on one side of the storage box, and a conveying pipe is fixedly connected to one end of the suction fan. This invention uses the suction fan to draw air from the outside, filters and absorbs humid air through a desiccant in a drying box, heats the air through a heating element in a heating box, and then sprays hot air through nozzles to heat the cement on the storage plate. This process heats the air inside the storage box. When the air inside the storage box becomes too hot, a fan dissipates the hot air, removing humid air and thus preventing moisture damage to the cement. This simple structure provides strong moisture protection, effectively preventing cement from clumping due to moisture, ensuring cement storage quality, reducing damage rates, and saving costs.

[0004] Existing cement storage devices for preventing caking have drawbacks, such as storing bagged cement together, exposing the remaining cement to the outside air when loading or unloading, resulting in poor preservation, and the inconvenience of replacing the desiccant. To overcome these disadvantages, this invention provides a cement storage device for preventing caking. Utility Model Content

[0014] 1. In this solution, a support base, support shaft, placement cylinder, gear, first slide groove, first screw, slider, fixing block, rack, partition, sleeve, fixing frame, opening, second screw, throttle, baffle, and guide rod are provided. Bagged cement is placed into the independent chamber formed by the two partitions of the placement cylinder through the opening of the sleeve. The drive motor rotates the first screw, which in turn causes the slider to slide along the first slide groove. This causes the fixing block and rack to move horizontally, driving the gear meshing with the rack to rotate, thus rotating the support shaft and placement cylinder. The cylinder rotates sequentially through different chambers to the opening of the sleeve for loading and unloading cement. The bagged cement is stored separately and independently, preventing it from piling up and being squeezed together, thus avoiding clumping caused by piling up and squeezing. Loading and unloading are also convenient. While loading and unloading one chamber, the cement in the other chambers remains sealed, reducing the contact between the remaining cement and the outside air and improving the preservation effect. By turning the second screw with the handle, the baffle moves down along the guide rod until it closes the opening of the sleeve, thus sealing the opening when cement is not needed.

In this solution, a slotted box, a fixed plate, a through-hole, a box cover, a vent, fixed bolts, a second sliding groove, a telescopic rod, a plug rod, a return spring, a socket, and a pull rod are provided. The slotted box, inserted into the placement cylinder, is filled with solid calcium chloride desiccant, which absorbs moisture from the cement in the chamber, preventing the cement from clumping. By unscrewing the fixed bolts, the slotted box can be pulled out. Pulling the pull rods on both sides in opposite directions compresses the telescopic rod and the return spring, causing the plug rod to move out of the socket. The box cover can then be opened, and the solid desiccant inside the slotted box can be poured out for replacement. Afterward, it can be inserted back into the chamber of the placement cylinder through the slot. The replacement of the solid desiccant is convenient and quick, avoiding poor moisture absorption due to untimely desiccant replacement. Attached Figure Description

[0027] like Figure 1-3 As shown, the driving assembly includes an L-shaped slider 7. The top plate of the support base 1 has a first groove 5. The slider 7 is slidably connected in the first groove 5. A first screw 6 is rotatably connected in the first groove 5. The slider 7 is threadedly connected to the first screw 6. The bottom end of the support shaft 2 extends to the bottom side of the support base 1 and is fixedly connected to a gear 4. A fixing block 8 is fixedly connected to the bottom end of the slider 7. A rack 9 is fixedly connected to the side of the fixing block 8 near the gear 4. The rack 9 meshes with the gear 4. A drive motor 10 is fixedly connected to the support base 1 at the position corresponding to the first screw 6. The output end of the drive motor 10 is fixedly connected to the first screw 6. When the drive motor 10 is started, the first screw 6 is rotated, which in turn drives the slider 7 to slide along the first groove 5. As a result, the fixing block 8 and the rack 9 move horizontally, which drives the gear 4 meshing with the rack 9 to rotate. As a result, the support shaft 2 and the placement cylinder 3 rotate, and the different chambers of the placement cylinder 3 are rotated sequentially to the opening 14 of the sleeve 12 for loading and unloading cement.

[0028] like Figure 4 As shown, the sealing assembly includes a baffle 17, a second screw 15 rotatably connected to the top surface of the sleeve 12, a handle 16 fixedly connected to the top of the second screw 15, a top plate of the baffle 17 threadedly connected to the second screw 15, a guide rod 18 fixedly connected to the top surface of the sleeve 12, and a top plate of the baffle 17 slidably connected to the guide rod 18.

[0030] Working principle: In use, bagged cement is placed into the independent chambers formed by the partitions 11 of the placement cylinder 3 through the opening 14 of the sleeve 12. The drive motor 10 is started, which drives the first screw 6 to rotate, thereby causing the slider 7 to slide along the first groove 5. This causes the fixing block 8 and rack 9 to move horizontally, driving the gear 4 meshing with the rack 9 to rotate. This, in turn, rotates the support shaft 2 and the placement cylinder 3, sequentially rotating the different chambers of the placement cylinder 3 to the opening 14 of the sleeve 12 for loading and unloading cement. The bagged cement is stored separately and independently, preventing accumulation and compression between them, and facilitating loading and unloading. While loading and unloading cement in one chamber, the cement in the other chambers remains sealed, reducing the exposure of the remaining cement to outside air. Contact is made by rotating the second screw 15 through the throttle 16, thereby driving the baffle 17 to move downward along the guide rod 18 until the opening 14 of the closed sleeve 12 is closed. When cement is not needed, it acts as a seal. The drawer box 20 inserted into the placement cylinder 3 is filled with solid calcium chloride desiccant, which plays a role in absorbing moisture and absorbing the moisture around the cement in the chamber to prevent the cement from clumping. By unscrewing the fixing bolt 25, the drawer box 20 can be pulled out. Pulling the pull rods 31 on both sides in opposite directions will compress the telescopic rod 27 and the return spring 29. The insertion rod 28 moves out of the insertion hole 30, and the box cover 23 can be opened to pour out the solid desiccant inside the drawer box 20 for replacement. Then, it can be inserted back into the chamber of the placement cylinder 3 through the insertion hole 19. The replacement of solid desiccant is convenient and quick.
