Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, specifically to a dry-mixed mortar drying device. Background Technology

[0002] Dry-mixed mortar is a dry mixture made by mixing cementitious materials (such as cement and gypsum), aggregates (such as quartz sand), mineral admixtures (such as fly ash) and functional additives (such as cellulose ethers and redispersible latex powder) in a certain proportion in a factory. When using it, you only need to add water and stir it according to the proportion. It has the characteristics of stable quality, convenient construction, environmental protection and high efficiency.

[0003] The aggregates (such as quartz sand) used in dry-mixed mortar can be either granular or powdered, depending on the purpose and performance requirements of the mortar. In actual formulations, graded mixing is often used to optimize overall performance. Quartz sand needs to be washed and the mud content should be ≤3% (high standard requirement ≤1%), otherwise it will affect the bonding properties.

[0004] In the mortar aggregate drying process, traditional drying equipment typically uses a stationary or only rotating heated tank for drying. The material accumulates heavily inside the tank, and the heat radiation from the heating plate cannot cover all areas, resulting in uneven heating of the material and localized over-drying or under-drying. This affects the stability of the finished mortar. In the early stages of drying, when the material has high moisture content and viscosity, the internal mixing components experience high resistance, which can easily cause overload damage to the transmission components. In the later stages of drying, the material's fluidity increases, and maintaining a strong mixing state will lead to energy waste. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned difficulties and provide a dry mortar drying device.

[0006] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: a dry mortar drying device, including a frame and a drying tank, two heating plates are symmetrically arranged on the frame, the drying tank is rotatably arranged on the frame, and a driving mechanism for driving the drying tank to rotate is provided on the frame.

[0007] The drying tank is equipped with a stirring mechanism, which includes a drive rod and stirring blades mounted on the drive rod. The drive mechanism drives the drying tank and the drive rod to rotate. The frame includes a lifting frame that drives the drying tank, heating plate and drive mechanism to tilt synchronously.

[0008] The drive mechanism includes a motor, a rotating drum, a hydraulic cylinder, and a positioning platform. The motor drives the rotating drum to rotate at the front end of the positioning platform, and the hydraulic cylinder drives the positioning platform to move axially within the lifting frame. A transmission platform is elastically slidably provided on the inner side of the rotating drum. The rotating drum drives the drying tank to rotate, and the transmission platform drives the drive rod to rotate.

[0010] As an improvement: the drying tank is equipped with a filter screen at the discharge port, and a baffle is slidably installed in the groove of the filter screen. A dustproof discharge mechanism and a discharge trough are provided below the drying tank. The dustproof discharge mechanism includes a lifting frame, a fitting frame and a cylinder. The bottom of the lifting frame is equipped with a corrugated square tube connected to one end of the discharge trough. The fitting frame is elastically connected to the lifting frame. The top of the fitting frame is equipped with an arc-shaped fitting platform that fits against the outside of the discharge port of the drying tank. The cylinder drives the lifting frame to move longitudinally on the frame.

[0011] As an improvement: the dustproof discharge mechanism also includes a pusher and a second cylinder. The pusher is provided with a push platform and a guide slide rod. The baffle is provided with a receiving platform that abuts against the push platform. The outer side of the fitting frame is provided with a guide groove that slides with the guide slide rod.

[0012] As an improvement: one end of the guide slide groove is provided with a reset surface one, the end of the guide slide rod is provided with a reset surface two that slides and engages with the reset surface one, the baffle is provided with a positioning slide shaft one that slides and engages with the through hole on the outside of the drying tank, and a reset spring is provided on the outside of the positioning slide shaft one.

[0013] As an improvement: a horizontal swing pressing mechanism is provided on the inner side of the discharge trough. The horizontal swing pressing mechanism includes a second motor and a horizontal swing platform. A closing platform that slides with the horizontal swing platform is provided on the inner side of the discharge trough. The second motor drives the horizontal swing platform to swing laterally at the closing platform. The bottom of the horizontal swing platform is an inclined surface.

[0014] As an improvement: the horizontal swing pressing mechanism also includes gear three, gear four and gear five.

[0015] As an improvement: multiple support rods are provided at both ends of the drive rod, scrapers are provided on the outside of the support rods, and connecting rods are provided between the corresponding support rods at both ends of the drive rod, with multiple stirring blades inclinedly arranged on the connecting rods.

[0016] The advantages of this invention compared to existing technologies are as follows: Through structural innovation and functional integration, this invention systematically solves the technical problems of traditional dry-mixed mortar drying devices in terms of uniformity, efficiency, dust prevention, and maintenance, and has significant engineering application value and market competitiveness. Specifically:

[0017] 1. The drying tank rotates continuously under the drive mechanism, and with the symmetrical radiation heating of the heating plate, the drying tank is heated evenly. The material inside the drying tank changes position continuously during the rotation of the drying tank, and receives heat from all directions, avoiding the uneven heating problem of traditional fixed tanks.

[0018] 2. The drive mechanism controls the clutch of the transmission table through a hydraulic cylinder, which can flexibly switch between the synchronous rotation of the drying tank and the stirring mechanism or the rotation of the stirring mechanism alone. When the material has high moisture content in the early stage of drying, only the drying tank rotates to reduce resistance; when the moisture content decreases in the later stage, the stirring mechanism is started synchronously to enhance mixing, thereby reducing energy consumption while ensuring the drying effect.

[0019] 3. The drive platform and the stirring mechanism are connected by an inclined plane and elastically linked by a spring. When the stirring resistance is too high, the drive platform automatically moves backward to compress the spring, preventing damage to components from hard impacts and improving the safety of equipment operation.

[0020] 4. The dustproof discharge mechanism is driven by a cylinder to raise the lifting frame, so that the arc-shaped contact platform of the contact frame elastically fits the discharge port of the drying tank to form a physical seal; the baffle normally closes the discharge port under the action of the spring to prevent dust from overflowing during the drying process. When discharging, the pusher automatically pushes the baffle open through the inclined structure. After the discharge is completed, the spring resets and closes. No manual contact with high-temperature parts is required throughout the process, ensuring operational safety.

[0021] 5. The horizontal oscillating pressing mechanism uses eccentric gear transmission to convert the rotational motion of the motor into the reciprocating oscillation of the horizontal oscillating table. Its bottom inclined surface continuously squeezes the material in the discharge trough, which can not only break up small clumps, but also spread the accumulated material evenly, ensuring continuous and stable discharge and reducing the frequency of manual clearing.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings.

[0037] Combined with appendix Figure 1 and attached Figure 2As shown, a dry-mixed mortar drying device includes a frame 1 and a drying tank 2. Two heating plates 3 are symmetrically arranged on the frame 1. The drying tank 2 is rotatably mounted on the frame 1. The drying tank 2 is equipped with an exhaust structure. A stirring mechanism 4 is provided inside the drying tank 2. A driving mechanism 5 is provided on the frame 1 to drive the drying tank 2 to rotate. The driving mechanism 5 drives the drying tank 2 and the stirring mechanism 4 to rotate. The frame 1 includes a lifting frame 16 that drives the drying tank 2, the heating plates 3 and the driving mechanism 5 to tilt synchronously. A dustproof discharge mechanism 6 and a discharge trough 7 are provided below the drying tank 2. A horizontal pressing mechanism 8 is provided inside the discharge trough 7.

[0038] Combined with appendix Figure 1 and attached Figure 3 As shown, the frame 1 includes a base frame 11, with a front side frame 12 and a rear side frame 15 at the front and rear ends of the base frame 11, respectively. A rotating platform 13 and an outer side frame 14 are rotatably mounted on the front side frame 12. The ends of the drying tank 2 and the stirring mechanism 4 are rotatably connected to the rotating platform 13. The heating plate 3 is mounted on the outer side frame 14, and the end of the outer side frame 14 is connected to the lifting frame 16. A hydraulic cylinder 17 is hinged on the base frame 11, and the output end of the hydraulic cylinder 17 is hinged to the lifting frame 16. When the drying tank 2 is placed at a slight tilt, the lifting frame 16 is placed on the rear side frame 15.

[0039] Combined with appendix Figure 2 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 and attached Figure 8 As shown, the drive mechanism 5 includes a motor 51, a rotating drum 52, a hydraulic cylinder 53, and a positioning platform 54. The motor 51 and hydraulic cylinder 53 are fixed to the lifting frame 16. The output end of the motor 51 is equipped with a gear 511. The outer side of the rotating drum 52 is equipped with a gear 521 that meshes with gear 511. The rear end of the rotating drum 52 is rotatably engaged with the front end of the positioning platform 54. The hydraulic cylinder 53 drives the positioning platform 54 to move axially within the lifting frame 16. A transmission platform 55 is elastically slidably mounted on the inner side of the rotating drum 52. One end of the drying tank 2 is equipped with a gear ring 26, and the front end of the rotating drum 52 is equipped with a gear that meshes with the gear ring 26. The gear ring 522 has a positioning slide 523 that slides with the transmission platform 55 at the through hole inside the rotating cylinder 52. The front end of the transmission platform 55 has a drive insertion platform 56. The end of the drive rod 41 has a transmission platform 46. The end of the transmission platform 46 has a drive slot 47 that inserts with the drive insertion platform 56. The sides of the drive insertion platform 56 and the drive slot 47 are both inclined. The rear end of the transmission platform 55 has a positioning slide rod 551 that slides with the through hole at the rear end of the rotating cylinder 52. A spring 552 is provided between the rear end of the transmission platform 55 and the inside of the rotating cylinder 52. The rotating table 13 has a braking structure to prevent the drying tank 2 from rotating.

[0040] In the drying operation of dry-mixed mortar aggregate, ordinary driving methods are difficult to achieve efficient coordinated operation between the drying tank and the mixing mechanism, resulting in uneven material drying and low efficiency. To solve the above problems, this drying device proposes an innovative structure of driving mechanism 5, which consists of components such as motor 51, rotating drum 52, hydraulic cylinder 53, and displacement platform 54. Each component works together to achieve precise driving.

[0041] Motor 51 serves as the power source. Its output gear 511 meshes with gear 521 on the outside of the rotating drum 52. After motor 51 starts, it drives the rotating drum 52 to rotate through gear transmission. The gear ring 522 at the front end of the rotating drum 52 meshes with the gear ring 26 at one end of the drying tank 2, thereby driving the drying tank 2 to rotate on the frame 1. This allows the heating plate 3 to heat the drying tank 2 evenly, and the mortar inside the tank to continuously change position, fully receiving the heat transferred by the heating plate 3 while preventing the formation of large lumps.

[0042] The inner side of the rotating drum 52 is provided with a positioning slide 523, and the transmission platform 55 can slide elastically inside it. The positioning slide rod 551 at the rear end of the transmission platform 55 slides in cooperation with the through hole at the rear end of the rotating drum 52, and a spring 552 is provided between the two. Before the drying operation, the hydraulic cylinder 53 drives the displacement platform 54 to move axially within the lifting frame 16, which drives the rotating drum 52 to slide forward. The spring 552 pushes the transmission platform 55 forward, so that the drive insertion plate 56 at the front end of the transmission platform 55 is inserted into the drive slot 47 of the transmission platform 46 at the end of the drive rod 41 in the stirring mechanism 4. At this time, the rotating drum 52 rotates and drives the stirring mechanism 4 to rotate synchronously.

[0043] In the early stage of drying, the mortar aggregate contains a large amount of water after washing, increasing its weight and viscosity, which hinders the rotation of the mixing mechanism 4. If the mixing mechanism 4 is rigidly connected to the drive mechanism 5, it will cause damage to either the mixing mechanism 4 or the drive mechanism 5. To improve safety, when the rotation of the mixing mechanism 4 is obstructed, the first transmission platform 46 remains stationary, while the second transmission platform 55 tends to rotate. Since the sides of the drive insertion platform 56 and the drive slot 47 are both inclined, the second transmission platform 55 will move backward when rotating, compressing the first spring 552. After the mortar aggregate is turned over by the rotation of the drying tank 2, the resistance of the mixing mechanism 4 decreases, and the first spring 552 pushes the second transmission platform 55 back, causing the drive insertion platform 56 to re-insert into the drive slot 47, driving the mixing mechanism 4 to rotate. In the later stage of drying, as most of the water in the mortar aggregate evaporates, its weight decreases and its fluidity increases. The mixing mechanism 4 will continue to rotate with the drying tank 2, stirring the mortar aggregate in the tank, enhancing heat conduction and breaking up large clumps.

[0044] During the discharge stage, after the drying tank 2 is rotated downwards after discharge, the braking structure on the rotating platform 13 prevents the drying tank 2 from rotating. Then, the hydraulic cylinder 2 53 pushes the displacement platform 54 to move backwards, and the rotating drum 52 follows the displacement platform 54 to move backwards, so that the toothed ring 1 26 separates from the toothed ring 2 522. The transmission platform 2 55 is still coupled with the transmission platform 1 46 under the push of the spring 1 552. At this time, the drive mechanism 5 drives the stirring mechanism 4 to rotate, and the drying tank 2 stops rotating. During discharge, the hydraulic cylinder 1 17 pushes the lifting frame 16 to rise, increasing the tilt angle of the drying tank 2. The aggregate that has been broken down will fall from the filter screen 25 at the discharge port, while the unbroken agglomerated aggregate will continue to be broken down by the stirring mechanism 4.

[0045] Combined with appendix Figure 2 Appendix Figure 4 Appendix Figure 5 Appendix Figure 9 and attached Figure 10 As shown, the drying tank 2 is provided with a filter screen 25 at the discharge port. A baffle 21 is slidably provided in the groove of the filter screen 25. A positioning slide shaft 23 is provided on the baffle 21, which is slidably engaged with the through hole on the outside of the drying tank 2. A return spring 24 is provided on the outside of the positioning slide shaft 23. The dustproof discharge mechanism 6 includes a lifting frame 61, a fitting frame 62 and a cylinder 63. The lifting frame 61 is slidably mounted on the front frame 12. The cylinder 63 is fixed on the front frame 12. A corrugated square tube 66 connected to one end of the discharge trough 7 is provided at the bottom of the lifting frame 61. The bottom of the fitting frame 62 is slidably engaged with the inner groove of the lifting frame 61. A positioning slide shaft 622 is provided on the outside of the fitting frame 62. The positioning slide shaft 622 is slidably engaged with the through hole on the outside of the lifting frame 61. A spring 623 is provided on the outside of the positioning slide shaft 622. An arc-shaped mounting platform 621 is provided on the top of the fitting frame 62, which is engaged with the outside of the discharge port of the drying tank 2.

[0046] Combined with appendix Figure 10 As shown, the dustproof discharge mechanism 6 also includes a pusher 64 and a second cylinder 65. The pusher 64 is provided with a push platform 641 and a guide slide rod 642. The baffle 21 is provided with a receiving platform 22 that abuts against the push platform 641. The outer side of the fitting frame 62 is provided with a guide groove 624 that slides with the guide slide rod 642. One end of the guide groove 624 is provided with a reset surface 625, and the end of the guide slide rod 642 is provided with a reset surface 643 that slides with the reset surface 625.

[0047] In the mortar aggregate discharge stage, traditional equipment is prone to problems such as dust overflow and material leakage, which not only pollute the environment but also waste resources. Moreover, since the drying tank 2 is heated by the heating plate 3, manually opening the discharge port can easily cause burns. To overcome these problems, this device is designed with a dustproof discharge mechanism 6, which consists of a lifting frame 61, a fitting frame 62, a cylinder 1 63, a pusher 64, and a cylinder 2 65. Through the coordinated operation of multiple components, dust prevention and automatic discharge are achieved.

[0048] Before discharge, cylinder 63 is activated, pushing the lifting frame 61 to rise. The corrugated square tube 66 at the bottom remains connected to the discharge trough 7. When the lifting frame 61 is in place, cylinder 65 drives the pusher 64 to move obliquely. The pusher 641 on the pusher 64 abuts against the receiving platform 22 of the baffle 21, overcoming the elastic force of the return spring 24, so that the baffle 21 slides along the groove of the filter screen 25. The positioning slide shaft 23 moves in the through hole on the outside of the drying tank 2, so that the baffle 21 is removed from the filter screen 25 and the discharge port is opened. At this time, the guide slide rod 642 has slid out of the guide slide groove 624. Under the action of spring 623, the top arc-shaped contact platform 621 of the contact frame 62 is tightly attached to the outside of the discharge port of the drying tank 2, forming a preliminary seal. When discharging, the mortar aggregate is filtered through the filter screen 25 and falls into the discharge trough 7 through the corrugated square tube 66.

[0049] After the material is discharged, cylinder 65 drives pusher 64 to move in the opposite direction. The reset surface 643 at the end of guide slide rod 642 contacts the reset surface 625 at one end of guide slide groove 624. The inclined structure causes the bonding frame 62 to automatically descend and reset, separating the bonding frame 62 from the discharge port of drying tank 2. Then, guide slide rod 642 is reinserted into guide slide groove 624. When pusher 64 moves, baffle 21 closes the discharge port again under the action of reset spring 24. Finally, cylinder 63 retracts, lifting frame 61 descends, and one discharge cycle is completed.

[0050] Combined with appendix Figure 2 Appendix Figure 11 Appendix Figure 12 and attached Figure 13 As shown, the horizontal sway pressing mechanism 8 includes a second motor 81 and a horizontal sway platform 82. The inner side of the discharge trough 7 is provided with a closing platform 71 that slides with the horizontal sway platform 82. There is a gap between the bottom of the closing platform 71 and the bottom wall of the discharge trough 7. The second motor 81 is fixed to the outside of the discharge trough 7. The second motor 81 drives the horizontal sway platform 82 to swing laterally at the closing platform 71. The bottom of the horizontal sway platform 82 is an inclined surface. The horizontal sway pressing mechanism 8 also includes a third gear 83, a fourth gear 84, and a fifth gear 85. The eccentric parts of the fourth gear 84 and the fifth gear 85 are rotatably connected to the top of the horizontal sway platform 82. The output end of the second motor 81 is connected to the eccentric part of the third gear 83. The eccentric distances of the third gear 83, the fourth gear 84, and the fifth gear 85 are the same. The third gear 83 meshes with the fourth gear 84 and the fifth gear 85 located on both sides respectively.

[0051] During the discharge process of dry-mixed mortar, the material is often loose and uneven, and accumulates in the discharge trough, resulting in poor discharge and even blockage of the channel, which seriously affects the continuity of production. In order to overcome this problem, this drying device is designed with a horizontal swing pressing mechanism 8, which consists of a motor 2 81, a horizontal swing table 82, a gear 3 83, a gear 4 84 and a gear 5 85, etc. It achieves efficient pressing by means of gear transmission and mechanical swing.

[0052] Motor 2 81 is fixed on the outside of the discharge trough 7 as a power source, and its output end is connected to the eccentric part of gear 3 83. Gear 3 83 meshes with gear 4 84 and gear 5 85 on both sides respectively, and the eccentric distance of the three gears is the same. The eccentric parts of gear 4 84 and gear 5 85 are rotatably connected to the top of the horizontal swing platform 82. The bottom of the horizontal swing platform 82 is designed as an inclined surface, which can swing laterally at the closing platform 71 inside the discharge trough 7.

[0053] When motor 2 81 starts, it drives gear 3 83 to rotate. Since gear 3 83 meshes with gear 4 84 and gear 5 85, gear 4 84 and gear 5 85 will rotate synchronously. Due to the eccentric design of the gears, during rotation, as shown in the attached... Figure 13 In the middle, gear 3 83 rotates counterclockwise, while gears 4 84 and 5 85 rotate clockwise. Since the output end of motor 2 81 is connected to the eccentric part of gear 3 83, the position of the eccentric part of gear 3 83 remains unchanged. When rotating 90°, the distance between the eccentric points of gear 3 83 and gear 4 84 increases, while the distance between the eccentric points of gear 3 83 and gear 5 85 decreases. This causes gears 4 84 and gear 5 85 to push the horizontal swing platform 82 to the left on the closing platform 71 through the rotational connection point with the top of the horizontal swing platform 82. Subsequently, when rotating 180°, it pushes the horizontal swing platform 82 to the left on the closing platform 71. As the gear moves upward to the right, the continuous rotation of gear three 83 causes the horizontal swing platform 82 to swing laterally. Since gear four 84 and gear five 85 are located on both sides of gear three 83, and the horizontal swing platform 82 can only move laterally, gear three 83, gear four 84, and gear five 85 always remain in mesh. During the swinging process, the inclined surface at the bottom of the horizontal swing platform 82 continuously squeezes and flattens the material in the discharge trough 7, further breaking up small lumps of mortar aggregate, spreading the accumulated aggregate evenly, avoiding material accumulation and blockage, and enabling the mortar aggregate to be output evenly and stably from the discharge trough.

[0054] Combined with appendix Figure 2 Appendix Figure 5 and attached Figure 6 As shown, the stirring mechanism 4 includes a drive rod 41, with multiple support rods 42 at both ends of the drive rod 41, a scraper 43 on the outer side of the support rod 42, and a connecting rod 44 between the support rods 42 at both ends of the drive rod 41, with multiple stirring blades 45 inclined on the connecting rod 44.

[0055] When mortar aggregate is dried, the material tends to accumulate on the wall of the drying tank, causing local overheating. At the same time, the material inside the tank is not mixed evenly, resulting in poor drying effect and low efficiency. To solve these problems, this drying device is designed with a stirring mechanism 4, which consists of a drive rod 41, a support rod 42, a scraper 43, a connecting rod 44, and a stirring blade 45. The components work together to achieve efficient stirring and scraping of the wall.

[0056] The power of the stirring mechanism 4 comes from the drive mechanism 5. When the drive plate 56 of the transmission platform 2 55 of the drive mechanism 5 is inserted into the drive slot 47 of the transmission platform 1 46 at the end of the drive rod 41, the motor 1 51 drives the rotating drum 52 to rotate. At the same time, the drive rod 41 starts to work, and the support rods 42 at both ends of the drive rod 41 rotate accordingly. The outer scraper 43 slides close to the inner wall of the drying tank 2, scraping off the mortar adhering to the tank wall and preventing the aggregate from sticking to the inner wall of the drying tank 2. At the same time, the connecting rod 44 between the corresponding support rods 42 at both ends of the drive rod 41 also rotates together. The inclined stirring blades 45 on it throw the material towards the tank wall through centrifugal force during rotation, and push the material to move axially by using the tilt angle of the blades. This makes the material form a compound motion trajectory of circular motion and axial movement in the tank, so that the dry and wet components and coarse and fine particles in the dry mortar are fully mixed, ensuring uniform heating, accelerating the heat exchange rate, and improving the drying efficiency.

[0057] In specific implementation, the mortar aggregate is poured into the drying tank 2 through the inlet. Then, the drive mechanism 5 drives the drying tank 2 and the stirring mechanism 4 to rotate. The heating plate 3 heats the drying tank 2, and the heat of the drying tank 2 is evenly transferred to the internal material, causing the moisture in the mortar aggregate to evaporate. The evaporated water vapor is discharged through the exhaust structure on the drying tank 2. The exhaust structure is an exhaust pipe with micro-mesh or a ventilation system with valves. An insulation cover can be set on the outside of the drying tank 2 to reduce heat loss. After the material is dried, the angle of the drying tank 2 is increased, and the stirring mechanism 4 rotates to break up the lumps of aggregate. The material is discharged through the dustproof discharge mechanism 6 to achieve dustproof discharge. The horizontal pressing mechanism 8 squeezes and flattens the material entering the discharge trough 7, further breaking up small lumps of aggregate and preventing material accumulation and blockage. After the mortar aggregate is dried, cementitious materials, admixtures and additives can be added and mixed by the stirring mechanism 4, and the device can be used as a mixing equipment.
