Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to a cement production raw material lifting and drying device. Background Technology

[0002] Cement is a powdered hydraulic inorganic binder widely used in the construction of infrastructure such as buildings, roads, and bridges. The cement production process mainly includes raw material preparation, raw meal preparation, clinker calcination, and cement grinding. Among these, the drying and crushing of raw materials are crucial steps in the raw meal preparation stage.

[0003] Utility model patent with authorization announcement number CN202223272302.3 discloses a circulating dryer for raw materials in cement production. This circulating dryer includes a base plate, with conveying pipes fixedly connected to both sides of the upper end of the base plate via support plates. Feed pipes are fixedly connected to the upper sidewalls of two adjacent conveying pipes at an incline. A dispersion processing shell is fixedly connected between the two feed pipes. The dispersion processing shell has a funnel-shaped structure, and several dispersion blocks are fixedly connected at equal intervals on the outer circumference of its upper end. The utility model discloses a dispersion processing shell between the two conveying pipes, containing multiple dispersion blocks and a rotating rod with a sliding plate. When the conveying shaft in the conveying pipe transports the raw material back into the dispersion processing shell, a first motor rotates the rotating rod, causing the sliding plate and multiple dispersion blocks to disperse the raw material, facilitating the circulating heating and drying of the raw material by the first heating plate.

[0004] Although the circulating dryer for cement production raw materials is convenient for heating cement production raw materials, the device still has the following problems in actual use: the device drives the rotating rod to rotate through the first motor and drives the conveyor shaft to rotate through the second motor. Since the device relies on the coordinated operation of multiple motors during operation, each motor needs to consume electrical energy independently, thus accumulating a high overall energy consumption. In view of this, we propose a cement production raw material lifting and drying device. Utility Model Content

The stirring shaft 28 passes into the cylinder 2, and multiple stirring rods 280 are fixed near the bottom of the outer wall of the stirring shaft 28; a first bevel gear 24 is fixed at the top of the outer wall of the stirring shaft 28, and second bevel gears 25 mesh on both sides of the first bevel gear 24, with the second bevel gears 25 coaxially positioned. A horizontal shaft 26 is connected by a key, and a third bevel gear 27 is coaxially keyed to the end of the horizontal shaft 26; hollow tubes 3 are installed on both the left and right sides of the cylinder 2, and the tubes 3 are open at the bottom. A second electric heating plate 30 is fixed to the inner wall of the tubes 3; an inclined return pipe 32 and a connecting pipe 33 are fixed to the upper and lower ends of the outer wall of the tubes 3, respectively. The return pipe 32 is connected to the inside of the cylinder 2, and the connecting pipe 33 is connected to the discharge pipe 21; an auger 31 is rotatably installed inside the tubes 3. The top end of the auger 31 passes through the top of the tubes 3 and is coaxially keyed to a fourth bevel gear 36. The fourth bevel gear 36 meshes with the corresponding third bevel gear 27.

[0032] In this embodiment, a crossbeam 34 is provided above the cylinder 2. Two second support plates 35 are fixed at both ends of the bottom of the crossbeam 34. The bottom ends of the second support plates 35 are fixedly connected to the top of the cylinder 3. Two first support plates 22 are also fixed at the bottom of the crossbeam 34. The bottom ends of the first support plates 22 are fixedly connected to the top of the cylinder 2. A horizontal shaft 26 passes through the first support plates 22 and the second support plates 35 and is rotatably connected to the first support plates 22 and the second support plates 35. The first motor 23 is fixedly connected to the top of the crossbeam 34 by bolts. The first support plates 22 and the second support plates 35 provide support and fixation for the crossbeam 34, while the crossbeam 34 provides support for the first motor 23, ensuring the installation stability of the first motor 23.

[0033] In this embodiment, support legs 10 are fixed at the four corners of the bottom of the base 1, and the support legs 10 are fixedly connected to the base 1 by bolts. The support legs 10 provide stable support for the base 1, ensuring the stability of the base 1.

[0034] In this embodiment, the cylinder 2 is fixedly connected to the base 1 by bolts, and the tube 3 is fixedly connected to the base 1 by bolts. The bolt fixing method ensures the reliability and stability of the installation between the cylinder 2 and the tube 3 and the base 1.

[0035] It is understood that the top of the cylinder 2 in this embodiment is equipped with a feed inlet, which facilitates the addition of cement production raw materials into the cylinder 2, thereby facilitating the drying of the cement production raw materials.

[0036] In practical use, the user first connects the power supply to the first motor 23, the first heating plate 20, and the second heating plate 30. The first motor 23, the first heating plate 20, and the second heating plate 30 begin to work. The output shaft of the first motor 23 rotates, driving the stirring shaft 28, the first bevel gear 24, and multiple stirring rods 280 to rotate. The multiple stirring rods 280 stir the cement production raw materials. At the same time, the first heating plate 20 heats and dries the cement production raw materials. Simultaneously, the first bevel gear 24 drives the second bevel gears 25 on both sides to rotate, and the second bevel gears 25 drive the horizontal shaft 26 and the third bevel gear... When wheel 27 rotates, the third bevel gear 27 drives the fourth bevel gear 36 to rotate, and the fourth bevel gear 36 drives the auger 31 to rotate. At this time, the cement production raw materials in the cylinder 2 enter the pipe 3 through the discharge pipe 21 and the connecting pipes 33 on both sides. As the auger 31 rotates, the cement production raw materials rise along the pipe 3. At the same time, the second electric heating plate 30 heats and dries the cement production raw materials. When the cement production raw materials move to the return pipe 32, the cement production raw materials are circulated back into the cylinder 2 through the return pipe 32 for heating and drying. This cycle is repeated to continuously heat and dry the cement production raw materials.

[0037] Example 2

[0038] Please see Figures 4-5As shown, this embodiment provides the following technical solution based on embodiment 1: A discharge section 4 is installed between the bottom openings of the two tube bodies 3. The discharge section 4 includes a plate 40 fixedly connected to the bottom of the tube body 3. A connecting cavity 401 is opened inside the plate body 40. Discharge holes 400 are opened at both ends of the plate body 40. The discharge holes 400 penetrate the connecting cavity 401. A discharge port 41 is installed at the bottom opening of the discharge hole 400. A gear 44 is rotatably installed at the center of the connecting cavity 401. A rack 43 meshes with both sides of the gear 44. A baffle 42 for blocking the discharge hole 400 is fixed at the end of the rack 43. A second motor 46 for driving the gear 44 to rotate is installed at the bottom of the plate body 40.

[0039] In this embodiment, the baffle 42 has a rectangular shape, and its dimensions are adapted to the dimensions of the connecting cavity 401. This design facilitates smooth horizontal movement of the baffle 42 within the connecting cavity 401, ensuring the stability of the baffle 42.

[0040] In this embodiment, two centrally symmetrical guide blocks 45 are fixed inside the connecting cavity 401, and a guide groove 430 is provided on the rack 43 to slide in connection with the guide blocks 45. The guide blocks 45 guide and limit the rack 43, ensuring the stability of the rack 43's movement.

[0041] In this embodiment, the rack 43 and the baffle 42 are integrally formed, and the two racks 43 are centrally symmetrical. The integrally formed rack 43 and baffle 42 have better connection strength, ensuring the service life of the rack 43 and baffle 42, while the centrally symmetrical design facilitates the synchronous relative movement of the baffles 42 on both sides.

[0042] When material discharge is required, the operator first turns on the power supply of the second motor 46. The second motor 46 starts to work, and the output shaft of the second motor 46 rotates, driving the gear 44 to rotate. The rotation of the gear 44 drives the racks 43 on both sides to move synchronously relative to each other. The racks 43 then drive the baffles 42 on both sides to move synchronously relative to each other. At this time, the baffles 42 on both sides move synchronously towards the center. When the baffles 42 disengage from the discharge hole 400, the cement production raw materials in the pipe body 3 are discharged to the outside through the discharge hole 400 and the discharge port 41.
