Description

Technical Field

[0001] This invention relates to the field of raw material drying technology, and more specifically to a raw material drying device for the production of concrete admixtures. Background Technology

[0002] Concrete admixtures are an indispensable component of modern concrete preparation. Although their dosage is low, they can significantly improve the workability, mechanical properties, and durability of concrete. With the increasing demands on concrete performance in construction projects, the types and applications of admixtures are expanding, including various functional products such as water-reducing agents, slump retainers, retarders, and accelerators. During the production of admixtures, the raw materials need to be dried to remove excess moisture.

[0003] First, conventional drying equipment mainly relies on surface contact or hot air convection for heat transfer. Heat is gradually conducted from the surface of the raw material to the interior. This method is prone to the phenomenon of "dry outside and wet inside", that is, the surface has dried into powder while the interior still contains a lot of moisture. Second, some raw materials undergo changes in physicochemical properties during dehydration. Under the combined effect of moisture and temperature, particles are prone to agglomeration, forming clumps of different sizes, which affects the quality of the final product after subsequent drying. Summary of the Invention

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Reference Figures 1-9This invention provides a raw material drying device for concrete admixture production, including a base plate 11. A support frame 10 is bolted to the upper surface of the base plate 11. A housing 5 is rotatably connected between the inner walls of both sides of the support frame 10 via bearings. A bracket 302 is bolted to the upper surface of the base plate 11. When the housing 5 is in a horizontal state, it contacts the bracket 302. The bracket 302 provides stable support for the horizontally placed housing 5. An inner shell 14 is rotatably connected to one inner wall of the housing 5 via bearings. A baffle 12 is welded to the edge of the inner wall of the housing 5. The baffle 12 is used to prevent the contents of the inner shell 14 from entering. The blank material leaks out from the opening of the inner shell 14. The inner shell 14 is a barrel structure with one end open, and the opening of the inner shell 14 faces the baffle 12. One side of the inner shell 14 is in contact with the baffle 12. The baffle 12 is used to cover the opening of the inner shell 14. A geared motor 13 that drives the inner shell 14 to rotate along the axis is fixed to one side of the outer wall of the outer shell 5 by bolts. Multiple first rollers 15 in a ring array are rotatably connected to the inner wall of the outer shell 5 through bearing seats. The first rollers 15 are in contact with the inner shell 14 and are used to support the rotating inner shell 14 to prevent the inner shell 14 from shaking during rotation.

[0030] It should be noted that the geared motor 13 is existing technology. The geared motor 13 is a speed reduction transmission device. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0031] The inner circumferential wall of the outer shell 5 is provided with a heating assembly 6 for heating the blank inside the inner shell 14. The heating assembly 6 includes a plurality of second heating wires 601 arranged in a ring array and fixed to the outer circumferential wall of the outer shell 5 by bolts. The plurality of second heating wires 601 are located between the outer shell 5 and the inner shell 14. When the second heating wires 601 are energized, they generate heat. The heat is transferred to the inner shell 14 through the space between the outer shell 5 and the inner shell 14, so as to uniformly heat the blank inside the inner shell 14 and achieve the drying process of the blank.

[0032] In this embodiment, a first guide pipe 16 is welded to one side of the baffle 12. A guide assembly 7 for feeding is provided on the side of the baffle 12 located inside the inner shell 14. The guide assembly 7 includes a guide plate 701 fixed to one side of the baffle 12 by bolts. Multiple L-shaped plates 702 in annular array are welded to the inner wall of the inner shell 14. When the reduction motor 13 is started, the reduction motor 13 drives the inner shell 14 to rotate clockwise. The rotation of the inner shell 14 can cause the blank to continuously turn over inside the inner shell 14. At the same time, the L-shaped plates 702 inside the inner shell 14 rotate clockwise with the inner shell 14. When the inner shell 14 rotates, the L-shaped plates 702 can lift the blank at the bottom upward. Multiple ribs are welded to the inner side of the L-shaped plates 702. The ribs are used to increase the structural strength of the L-shaped plates 702. After reaching a certain height (refer to...), Figure 5As shown), the guide plate 701 is V-shaped and inclined toward the first guide tube 16. The guide plate 701 is used to guide the dried blank in the inner shell 14 to the first guide tube 16. The lower end of the guide plate 701 is flush with the first guide tube 16 to ensure that the blank can smoothly enter the first guide tube 16. When the L-shaped plate 702 rotates to the highest point, the blank slides off the L-shaped plate 702 due to gravity and slides onto the guide plate 701. Then it slides into the first guide tube 16 along the inclined surface of the V-shaped guide plate 701. Please refer to Figure 7 A crushing assembly 1 for breaking up agglomerated raw materials is provided on one side of the baffle 12. The crushing assembly 1 includes a crushing shell 102 disposed on one side of the baffle 12. The crushing shell 102 is connected and fixedly connected to the first feed pipe 16. The first feed pipe 16 is used to transport the raw materials in the inner shell 14 to the crushing shell 102. A bottom cover 103 is welded to the outer circumference of the crushing shell 102. A strainer 104 is provided at the bottom of the crushing shell 102 and is located inside the bottom cover 103. A rotating rod is rotatably connected to the top outer wall of the crushing shell 102 via a bearing. 106. One end of the rotating rod 106 passes through the crushing shell 102 and is fixed with multiple rotating array blades 105 by bolts. The blades 105 are used to cut and crush the raw material entering the crushing shell 102, breaking up the agglomerated raw material formed during the drying process. A fixing frame 107 is fixed to the top outer wall of the crushing shell 102 by bolts. A servo motor 108 that drives the rotating rod 106 to rotate along the axis is fixed to the upper surface of the fixing frame 107 by bolts. When the servo motor 108 is started, the servo motor 108 drives the rotating rod 106 to rotate. The rotating rod 106 drives the blades 105 to rotate at high speed inside the crushing shell 102. When the raw material enters the crushing shell 102 from the first guide pipe 16, the high-speed rotating blades 105 cut and impact the raw material, breaking the lumps in the raw material into fine particles. The crushed raw material falls into the bottom cover 103 through the sieve holes on the strainer plate 104. The bottom of the bottom cover 103 is welded with a second guide pipe 101 that is inclined and connected to the bottom cover 103. The inclined second guide pipe 101 facilitates the automatic movement of the raw material in the bottom cover 103 under the action of gravity. The material slides down, and the bottom end of the second guide pipe 101 is connected and fixed to the baffle 12. The blank material in the bottom cover 103 is transported back to the inner shell 14 through the second guide pipe 101, realizing the recycling, crushing and drying of the blank material. This ensures that the agglomerated blank material can be fully broken up and dried again, solving the problem of uneven drying caused by the agglomeration of the blank material and improving the uniformity of the dried product. At the same time, the blank material is turned over so that it can fully contact the inner wall of the inner shell 14, thereby improving the heating efficiency and avoiding the occurrence of the "dry outside and wet inside" phenomenon.

[0033] It should be noted that the servo motor 108 is existing technology, and those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0034] like Figure 3 As shown, in this embodiment, a feeding assembly 4 is provided on one side of the baffle 12. The feeding assembly 4 includes a feed pipe 403 welded to one side of the baffle 12. The feed pipe 403 is inclined and passes through the baffle 12. A guide shell 402 connected to the feed pipe 403 is welded to the top of the feed pipe 403. The setting of the guide shell 402 increases the area of ​​the feed inlet, which facilitates the addition of blanks into the equipment. A second cover plate 401 is detachably connected to the top of the guide shell 402 by a latch. The second cover plate 401 can close the feed inlet when the equipment is running, reducing the heat loss inside the inner shell 14. Open the second cover plate 401 and pour the blank to be dried into the feed guide shell 402. The blank enters the feed pipe 403 through the feed guide shell 402 and then enters the inner shell 14 through the feed pipe 403, thus completing the addition of the blank.

[0035] In this embodiment, a discharge assembly 3 is provided on one side of the baffle 12. The discharge assembly 3 is located below the feeding assembly 4. The discharge assembly 3 includes a discharge pipe 303 welded to one side of the baffle 12 and the discharge pipe 303 passes through the baffle 12. The other end of the discharge pipe 303 is detachably connected to a first cover plate 304 by a latch. The first cover plate 304 is used to seal the discharge pipe 303 during the drying process to prevent heat loss and leakage of the blank. A hydraulic cylinder 301 is rotatably connected to the upper surface of the base plate 11 via a bearing seat. The telescopic end of the hydraulic cylinder 301 is rotatably connected to the outer shell 5. When the hydraulic cylinder 301 is started, the telescopic end of the hydraulic cylinder 301 extends and pushes the outer shell 5 to rotate upward with the support frame 10 as the fulcrum, causing the outer shell 5 and the inner shell 14 to tilt. At this time, the dried material in the inner shell 14 gathers towards the opening under the action of gravity. The first cover plate 304 is opened, and the material can be discharged from the equipment through the discharge pipe 303, which improves the convenience of the discharge operation.

[0036] It should be noted that the hydraulic cylinder 301 in this application is an actuator in a hydraulic system. It achieves the telescopic function by cooperating with the hydraulic system, and achieves precise control of the telescopic displacement of the hydraulic cylinder piston rod by cooperating with a magnetic switch, proximity switch or photoelectric switch. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0037] In this embodiment, the other end of the second guide pipe 101 is provided with a dehumidification assembly 2 for discharging moisture from the inner shell 14. The dehumidification assembly 2 includes an air inlet pipe 201 welded to the other end of the second guide pipe 101. The air inlet pipe 201 is connected to an external fan. A first heating wire 202 is provided inside the air inlet pipe 201. Both the air inlet pipe 201 and the first heating wire 202 are spiral-shaped. The spiral structure design can extend the air flow path in the air inlet pipe 201, so that the contact time between the air and the first heating wire 202 is longer and the heating is more complete. An air outlet pipe 203 is welded to the top of one side of the baffle 12. One end of the air outlet pipe 203 passes through the baffle 12 and extends to the rear end of the inner shell 14 (see reference). Figure 9 As shown), the exhaust pipe 203 and the L-shaped plate 702 do not interfere with each other in space, so that the intake pipe 201 takes in air from the front end and the exhaust pipe 203 exhausts air from the rear end, forming an airflow channel that runs through the inner shell 14, thereby more thoroughly removing the hot and humid air inside the inner shell 14. Function 1: The external fan delivers air into the inner shell 14 through the air inlet pipe 201. At the same time, the first heating wire 202 is energized and heats up the incoming air. After the heated air enters the inner shell 14, it can reheat the blank and further increase the temperature inside the inner shell 14. Meanwhile, the air outlet pipe 203 promptly discharges the hot and humid air inside the inner shell 14, forming an air circulation and accelerating the evaporation of moisture in the blank. Function 2: When air is delivered to the inner shell 14 through the air inlet pipe 201, it can also help blow the blank in the second guide pipe 101 to the depth of the inner shell 14, so as to avoid the blank accumulating inside the second guide pipe 101 or at the outlet, and ensure that the blank after circulating crushing can enter the inner shell 14. Function 3: The first heating wire 202 heats the incoming air, preventing low-temperature cold air from directly entering the inner shell 14 and causing a sudden drop in internal temperature, thus maintaining the temperature stability of the drying environment inside the inner shell 14 and ensuring that the drying efficiency is not affected.

[0038] It should be noted that the first heating wire 202 and the second heating wire 601 are both existing technologies, and those skilled in the art can set them according to actual needs, which will not be elaborated here.

[0039] like Figure 6As shown, in this embodiment, a pushing assembly 8 for assisting drying is provided on the side of the baffle 12 near the material guiding assembly 7. The pushing assembly 8 includes a fixing rod 801 fixed to one side of the baffle 12 by bolts. The fixing rod 801 is concentric with the inner shell 14, and the other end of the fixing rod 801 is rotatably connected to the inner shell 14, which can support the other end of the fixing rod 801. At the same time, the concentric arrangement ensures the stability of the inner shell 14 when rotating, and avoids unnecessary friction or jamming between the fixing rod 801 and the inner shell 14. Multiple equidistantly distributed... When the inner shell 14 rotates clockwise, the pusher 802 is in a relatively stationary state. Two symmetrical inclined surfaces 803 are opened on one side of the pusher 802. During the rotation, the blank in the inner shell 14 will contact the inclined surface 803 of the pusher 802. The design of the inclined surface 803 can generate left and right component forces on the blank, so that the blank forms a more complex flow trajectory in the inner shell 14, further enhancing the turning effect of the blank. The bottom of the pusher 802 is higher than the top of the L-shaped plate 702 to avoid the pusher 802 obstructing the rotation of the L-shaped plate 702.

[0040] like Figure 7As shown, in this embodiment, a connecting rod assembly 9 for driving the sluice plate 104 to move left and right is provided on the outer side of the rotating rod 106. The diameter of the bottom cover 103 is larger than the diameter of the crushing shell 102, and the diameter of the sluice plate 104 is larger than the diameter of the crushing shell 102 but smaller than the diameter of the bottom cover 103. This design allows the sluice plate 104 to completely cover the bottom opening of the crushing shell 102, ensuring that the raw material falling from the crushing shell 102 will not directly scatter outside the bottom cover 103. At the same time, the edge of the sluice plate 104 is located on the inner side of the bottom cover 103, providing sufficient space for the left and right movement of the sluice plate 104. The connecting rod assembly 9 includes a second roller 903 rotatably connected to the outer side of the rotating rod 106 via a bearing seat. Multiple sliding rods 902 are welded to the outer side of 104. These sliding rods 902 are divided into two symmetrical groups. One end of each sliding rod 902 passes through the bottom cover 103. The other ends of two adjacent sliding rods 902 are bolted to a connecting frame 901. The connecting frame 901 is L-shaped and contacts the second roller 903. When the servo motor 108 drives the rotating rod 106 to rotate, the second roller 903 rotates along with the rotating rod 106. Because the second roller 903 contacts the L-shaped connecting frame 901, it generates a periodic thrust on the connecting frame 901 during rotation. Since the two connecting frames 901 are fixedly connected to the slotted plate 104 via the sliding rods 902, when one side... When the connecting frame 901 is pushed by the second roller 903, it will drive the corresponding slide bar 902 to slide outward of the bottom cover 103, and at the same time drive the sprue plate 104 to move to that side, causing the other connecting frame 901 to move synchronously. When the wheel surface of the second roller 903 contacts and presses against the long arm of one of the connecting frames 901, the connecting frame 901 will drive the slide bar 902 connected to the connecting frame 901 to move to one side of the bottom cover 103, thereby pulling the sprue plate 104 to slide to that side. The sprue plate 104 will drive the other connecting frame 901 to move synchronously through the slide bar 902. The distance between the two connecting frames 901 is less than the diameter of the virtual circle formed by the second roller 903 rotating around 106, thus... This ensures that the second roller 903 can continuously and alternately squeeze the two connecting frames 901 during rotation, causing the sluice plate 104 to reciprocate left and right inside the bottom cover 103. When the second roller 903 disengages from one of the connecting frames 901 and contacts the other connecting frame 901, it will push the connecting frame 901 to move in the opposite direction, thereby causing the slide rod 902 and the sluice plate 104 to slide to the other side. Through the continuous rotation of the second roller 903, the sluice plate 104 achieves reciprocating left and right sliding inside the bottom cover 103, thereby causing the sluice plate 104 to sway left and right, effectively preventing the crushed material particles from clogging the screen holes, and ensuring that the crushed material can smoothly pass through the sluice plate 104 and fall into the bottom cover 103.

[0041] The working principle of this invention is as follows: Open the second cover plate 401, pour the blank to be dried into the guide shell 402, the blank enters the feed pipe 403 through the guide shell 402, and then enters the inner shell 14 through the feed pipe 403 to complete the addition of the blank; Then, when the second heating wire 601 is energized, it generates heat. The heat is transferred to the inner shell 14 through the space between the outer shell 5 and the inner shell 14, and the blank inside the inner shell 14 is heated evenly. At the same time, the reduction motor 13 is started, and the reduction motor 13 drives the inner shell 14 to rotate clockwise. The rotation of the inner shell 14 can make the blank continuously turn over inside the inner shell 14. At the same time, the L-shaped plate 702 inside the inner shell 14 rotates clockwise together with the inner shell 14. When the inner shell 14 rotates, the L-shaped plate 702 can lift the blank at the bottom upward. When the L-shaped plate 702 rotates to the highest point, the blank slides off the L-shaped plate 702 due to gravity and slides onto the guide plate 701. Then it slides into the first guide tube 16 along the inclined surface of the V-shaped guide plate 701. The raw material enters the crushing shell 102 through the first feed pipe 16. At this time, the servo motor 108 is started. The servo motor 108 drives the rotating rod 106 to rotate. The rotating rod 106 drives the blade 105 to rotate at high speed in the crushing shell 102. After the raw material enters the crushing shell 102 from the first feed pipe 16, the high-speed rotating blade 105 cuts and impacts the raw material, breaking the lumps in the raw material into fine particles. Simultaneously, the rotating rod 106 drives the second roller 903 to rotate together. When the wheel surface of the second roller 903 contacts and presses against the long arm of one of the connecting frames 901, the connecting frame 901 will drive the sliding rod 902 connected to the connecting frame 901 to move to one side of the bottom cover 103, thereby pulling the sluice plate 104 to slide to that side. The sluice plate 104 will drive the connecting frame 901 on the other side to move synchronously through the sliding rod 902. The distance between the two connecting frames 901 is smaller than the diameter of the second roller 903. When the second roller 903 disengages from one of the connecting frames 901 and contacts the other connecting frame 901, it will push the connecting frame 901 to move in the opposite direction, thereby driving the sliding rod 902 and the sluice plate 104 to slide to the other side, causing the sluice plate 104 to sway left and right. The crushed material falls into the bottom cover 103 through the sieve holes on the perforated plate 104, and the material in the bottom cover 103 is then transported back to the inner shell 14 through the second guide pipe 101. At the same time, the external fan delivers air into the inner shell 14 through the air inlet pipe 201, and the first heating wire 202 is energized to heat the incoming air. After the heated air enters the inner shell 14, it heats the blank a second time. Meanwhile, the air outlet pipe 203 promptly discharges the hot and humid air in the inner shell 14, forming an air circulation. This process is repeated until the raw material reaches the preset drying requirements.
