Description

Technical Field

[0001] This application relates to the field of cement production equipment technology, and in particular to a feeding device for cement production and processing. Background Technology

[0002] Cement production requires a large amount of limestone, silica-alumina, or clayey raw materials. Due to the large amount of raw materials needed, they are usually crushed and transported by lifting devices to replace manual labor.

[0003] For example, a "clay feeding and lifting device for cement production" disclosed in Chinese patent literature, publication number CN211919936U, includes a conveyor frame, a heating block installed on the inner wall of the conveyor frame, an auger inside the conveyor frame, and a first motor bolted to the bottom of the conveyor frame, with the output shaft of the first motor engaging with the bottom of the auger. This device, through the arrangement of the conveyor frame, heating block, auger, first motor, straight pipe, processing box, orifice plate, through hole, chute, slider, moving plate, reciprocating drive structure, and feed hopper, enables the clay feeding and lifting device for cement production to pre-treat the clay, preventing the directly conveyed solidified clay.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: 1. Directly lifting and conveying raw materials such as clay through a lifting device can easily cause the raw materials to stick together during the conveying process. On the one hand, this can easily cause blockages or residues of the raw materials, and on the other hand, it can lead to a reduction in the efficiency of subsequent processing steps; 2. During the conveying process, because the conveying angle is fixed, it cannot flexibly adapt to different production site layouts and process requirements, thus limiting the versatility of the equipment.

[0020] (3) The casters at the bottom of the support frame in this utility model make the entire raw material conveying assembly easy to move and transfer, facilitating production between different production areas;

[0021] (4) In this utility model, the second receiving hopper and the third receiving hopper are connected by a corrugated hose, which can maintain a good connection when the angle of the conveying cylinder is adjusted, and avoid raw material leakage. Attached Figure Description

A crushing unit 8 is fixedly installed on the outer wall of the crushing shaft 7. A filter screen 9, used in conjunction with the crushing unit 8, is installed inside the second receiving hopper 4. The high-speed rotation of the crushing shaft 7 and the crushing unit 8 impacts and crushes the raw material. Combined with the screening effect of the filter screen 9, this ensures that the raw material reaches the ideal particle size, improving the efficiency and product quality of subsequent production.

[0035] like Figure 5 As shown, the raw material conveying assembly 2 includes a movable support frame 10 and a conveying cylinder 11 mounted on the support frame 10. A rotatable auger is installed inside the conveying cylinder 11, which lifts and conveys the crushed raw material through bolts. A discharge hopper 12 and a third receiving hopper 13, which communicate with the inside of the conveying cylinder 11, are respectively fixedly installed on the lower side of the top end and the upper side of the bottom end of the conveying cylinder 11 by bolts. The third receiving hopper 13 is located below the second receiving hopper 4. The bottom of the conveying cylinder 11 is rotatably connected to one side of the upper surface of the support frame 10 by a rotating shaft. An adjustment assembly 14 is provided between the conveying cylinder 11 and the support frame 10 to adjust the angle between the conveying cylinder 11 and the support frame 10. The second receiving hopper 4 and the third receiving hopper 13 are connected by a corrugated hose 36.

[0036] Example 2:

[0037] like Figure 3 , 4As shown, this utility model discloses another technical solution, a feeding device for cement production and processing. The difference from embodiment 1 is that the two ends of the crushing shaft 7 pass through the side walls of the first receiving hopper 5 and the second receiving hopper 4 and are rotatably connected to the upper surface of the support frame 3 through bearings. The bearings are fixedly installed on the support frame 3. The support frame 3 is also equipped with a first driving component.

[0040] Specifically, the filter screen 9 adopts a semi-circular structure, and both of its two sides extend outward and are fixedly connected to the edge of the second receiving hopper 4 by bolts. The filter screen 9 is coaxially arranged with the crushing shaft 7. During the process of the first drive assembly driving the crushing shaft 7 to rotate, the hammer plate 21 rotates at high speed under the support of the fixed disc 19 and the fixed rod 20, and impacts and crushes the raw material. The raw material that meets the particle size requirements falls into the second receiving hopper 4 through the filter screen 9, while the raw material that does not meet the particle size requirements continues to be crushed in the crushing area.

[0041] Example 3:

[0042] like Figure 6-8 As shown, this utility model discloses another technical solution, a feeding device for cement production and processing. The difference from embodiment 1 is that the above-mentioned spiral auger is composed of a conveying shaft 22 and spiral blades 23 welded to the outer wall of the conveying shaft 22. Both ends of the conveying shaft 22 are rotatably connected to the conveying cylinder 11 through bearings, and the bottom end of the conveying cylinder 11 is fixedly installed with a second drive assembly 24 by bolts. The second drive assembly 24 is a drive motor. The output end of the drive motor is fixedly connected to the bottom end of the conveying shaft 22 and can drive the conveying shaft 22 to rotate.

[0043] Specifically, the pitch of the spiral blade 23 gradually increases from bottom to top, which allows the raw material to gradually accelerate during the conveying process, reducing the possibility of blockage and improving conveying efficiency.

[0044] Specifically, the adjustment assembly 14 includes a first telescopic cylinder 25 and a first telescopic rod 26. The bottom of the first telescopic cylinder 25 is rotatably connected to the support frame 10 via a rotating shaft, and the top of the first telescopic rod 26 is rotatably connected to the side wall of the conveying cylinder 11 via a rotating shaft. The top of the first telescopic cylinder 25 is open and the inside is hollow. The lower part of the first telescopic rod 26 is inserted into the first telescopic cylinder 25, and a fixing hole 27 is provided on the side wall of the first telescopic cylinder 25. A plurality of adjustment holes 28 that cooperate with the fixing holes 27 are evenly provided on the side wall of the telescopic rod along its length direction. The first telescopic cylinder 25 and the first telescopic rod 26 are fixed by a limiting pin 29 inserted into the adjustment hole 28 and the fixing hole 27.

[0045] Specifically, two sets of first telescopic cylinders 25 and first telescopic rods 26 are provided in the front and rear, and a support plate 30 is rotatably connected between the two first telescopic cylinders 25 via a rotating shaft. A drive box 31 is fixedly installed on the upper surface of the support plate 30 by bolts. A gear 32 is rotatably connected inside the drive box 31 via a rotating shaft, and an adjusting rod 33 is fixedly connected to one end of the gear 32. One end of the adjusting rod 33 extends out of the side wall of the drive box 31. A rack 34 that meshes with the gear 32 is slidably connected inside the drive box 31. Both ends of the rack 34 extend out of the drive box 31, and the top of the rack 34 is rotatably connected to the side wall of the conveying cylinder 11 via a rotating shaft. In this embodiment, a clamp can be fixed to the side wall of the conveying cylinder 11. The rack 34 and the first telescopic rod 26 are rotatably connected to the clamp on the side wall of the conveying cylinder 11 to avoid damaging the structure of the conveying cylinder 11.

[0046] Specifically, casters 35 are bolted to the four corners of the bottom of the support frame 10, and casters are also bolted to the four corners of the bottom of the support frame 3.

[0047] This utility model provides a feeding device for cement production and processing. In use, the cement raw material to be processed is poured into the feeding hopper 6, and the raw material enters the first receiving hopper 5. The first drive assembly is activated, driving the crushing shaft 7 to rotate. The crushing unit 8 on the crushing shaft 7 begins to crush the raw material. During the crushing process, the hammer plate 21 rotates at high speed under the support of the fixed disc 19 and the fixed rod 20, impacting and crushing the raw material. Raw material that meets the particle size requirements falls through the filter screen 9 into the second receiving hopper 4, while raw material that does not meet the particle size requirements continues to be crushed in the crushing area. The raw material falling into the second receiving hopper 4 enters the third receiving hopper 13 through the corrugated hose 36, and then enters the conveying cylinder 11. The second drive assembly 24 is activated, driving the conveying shaft 22 to rotate. The spiral blades 23 on the conveying shaft 22 convey the raw material upwards. Because the pitch of the spiral blades 23 gradually increases from bottom to top, the raw material gradually accelerates during the conveying process, eventually exiting from the discharge hopper 12. Output, proceed to the next production process; when the angle of the feeding cylinder 11 needs to be adjusted, rotate the adjusting rod 33, the adjusting rod 33 drives the gear 32 to rotate, the gear 32 meshes with the rack 34, causing the rack 34 to move up and down, thereby driving the feeding cylinder 11 to rotate around its rotation connection point with the support frame 10. After adjusting to the appropriate angle, insert the limiting pin 29 into the corresponding adjusting hole 28 and fixing hole 27 to fix the first telescopic cylinder 25 and the first telescopic rod 26, keeping the angle of the feeding cylinder 11 stable; when it is necessary to move the feeding device to a new position, use the universal wheels at the bottom of the support frame 10 and the support frame 3 to easily move the device to the designated position.

[0048] 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.
