Description

Technical Field

[0001] This invention relates to the technical field of drying equipment, and more particularly to a constant temperature drying device for the production of water-reducing agents. Background Technology

[0002] In the industrial production of water-reducing agents, the extruded material typically contains high moisture content and must undergo effective drying to meet the quality standards of the finished product. Currently, the commonly used drying method involves placing the wet material into a drying tank and spraying hot air upwards through jet pipes at the bottom of the tank. This causes the water-reducing agent particles to suspend or stratify under the influence of the airflow, increasing the contact area with the hot air and achieving rapid drying. Simultaneously, the water vapor generated during the drying process is discharged through an exhaust pipe at the top to maintain a balanced humidity level in the drying environment.

[0003] However, in actual operation, existing drying equipment has a significant technical deficiency: because the hot air flows from bottom to top, the humid air carrying a large amount of moisture is difficult to completely expel in time when it rises to the upper space of the drying tank, causing water vapor to accumulate in the top area of ​​the tank. When this water vapor comes into contact with the relatively cooler inner wall of the drying tank, condensation easily occurs, forming condensate droplets that eventually drip back into the material layer. This repeated wetting process not only directly reduces drying efficiency but may also cause partially dried water-reducing agent particles to reabsorb moisture, resulting in uneven drying, clumping, and even quality degradation. Furthermore, to overcome the negative effects of condensation, it is often necessary to extend the drying time or increase the hot air temperature, which not only increases energy consumption but also places higher demands on the stable operation of the equipment and the thermal stability of the product. Summary of the Invention

[0004] In view of this, the present invention provides a constant temperature drying device for the production of water-reducing agents, which can overcome the disadvantage that existing drying devices tend to form condensate droplets on the top of the inner wall of the drying tank during use, which eventually drip into the water-reducing agent and thus affect the drying efficiency.

[0006] Furthermore, it is particularly preferred that the rotating assembly includes: a first motor mounted on the top of the drying tank; a first gear connected to the output shaft of the first motor; and a second gear connected to the rotating rod, wherein the second gear meshes with the first gear.

[0007] Furthermore, it is particularly preferred that the drainage assembly includes: a fixed base connected to the top of the drying tank, and the upper end of the rotating rod being rotatably connected to the fixed base; a water suction pipe connected to the fixed base, and the lower end of the water suction pipe being located inside the rotating rod; a liquid level sensor installed inside the rotating rod, and the rotating rod having square holes spaced apart circumferentially, the square holes being located inside the water storage box.

[0008] Furthermore, it is particularly preferred that the device also includes a striking assembly, which comprises: a drive motor mounted on the outer wall of the drying tank; a full gear connected to the output shaft of the drive motor; a rotating gear ring rotatably connected to the inner wall of the drying tank, and the rotating gear ring meshing with the full gear; and an elastic rope circumferentially spaced and connected to the inner wall of the rotating gear ring.

[0009] Furthermore, it is particularly preferred that the device also includes: a connecting cylinder connected to the lower end of the rotating rod; a scraper circumferentially spaced and connected to the outer wall of the connecting cylinder; a lever frame slidably connected to the scraper; and a moving mechanism disposed on the connecting cylinder for driving the lever frame to move.

[0010] Furthermore, it is particularly preferred that the moving mechanism includes: a bevel gear ring connected to the inner bottom of the drying tank; a bevel gear rotatably connected to the inner wall of the connecting cylinder at circumferential intervals; a rotating rod rotatably connected to the connecting cylinder at circumferential intervals, and the rotating rod has evenly spaced elliptical grooves; a pulley assembly, through which the bevel gear and the rotating rod are driven; a connecting ring evenly spaced connected to the actuating frame; and balls rotatably connected to the inner wall of the connecting ring, and the balls roll within the elliptical grooves.

[0011] Furthermore, particularly preferably, it also includes: a storage frame connected to the top of the base plate; a connecting pipe connected to the storage frame and maintaining communication, and the connecting pipe being connected to and maintaining communication with the drying tank; a screw rod rotatably connected to the inside of the connecting pipe; a second motor mounted on the storage frame; a third gear connected to the output shaft of the second motor; a fourth gear connected to the rotating shaft of the screw rod, and the fourth gear meshing with the third gear; and a preheating mechanism disposed on the connecting pipe for preheating the water-reducing agent conveyed by the screw rod.

[0013] Beneficial effects: 1. The present invention utilizes the coordinated operation of a conical frame, condenser tube, scraper, and water storage box. The condenser tube condenses the water vapor accumulated at the top of the drying tank, and the scraper, driven by a rotating rod, scrapes the condensate droplets into the water inlet channel, guides them through the vertical pipe into the water storage box, and then automatically discharges them through the drainage component. This design effectively prevents condensate from dripping back into the water-reducing agent, avoids secondary moisture absorption by the material, significantly improves drying uniformity and efficiency, and reduces energy consumption.

[0014] 2. The elastic rope of the present invention, driven by the rotating toothed ring, can continuously strike the lower layer of large-particle water-reducing agent. Combined with the reciprocating movement of the agitator, the double action breaks and disperses the clumped material. At the same time, the scraper rotates with the connecting cylinder to push the material towards the center of the filter plate, ensuring that the hot air penetrates the material layer evenly, significantly reducing the drying dead corners and improving the overall drying quality.

[0015] 3. The preheating mechanism of the present invention can use the hot and humid air discharged from the exhaust pipe to preheat the water-reducing agent in the connecting pipe, and the screw rod simultaneously conveys the material to the drying tank. This design can not only avoid the water-reducing agent from clumping, but also recover waste heat energy, reduce the heating load of the hot air system, and achieve energy-efficient utilization and energy-saving optimization of the production process.

Detailed Implementation

[0029] Example: A constant temperature drying device for the production of water-reducing agents, such as... Figures 1-5As shown, the device includes a base plate 1, a drying tank 2, an exhaust pipe 3, an air jet pipe 4, a filter plate 5, a conical frame 6, a condenser pipe 7, a rotating rod 8, a scraper frame 9, a water storage box 10, a vertical pipe 11, a rotating assembly, and a drainage assembly. The device is equipped with a main controller (not shown in the figure), which controls the operation of related electrical components. The drying tank 2 is connected to the top right side of the base plate 1. An inlet is located on the upper left side of the drying tank 2, and an outlet is located on the lower right side. Electric valves are installed at both the inlet and outlet of the drying tank 2. An exhaust pipe 3 is connected to the upper left side of the drying tank 2 and remains open. A one-way vent valve is installed on the exhaust pipe 3 to prevent the water-reducing agent from being discharged through the exhaust pipe 3. An air jet pipe 4 is connected to the lower interior side of the drying tank 2, with the front end of the air jet pipe 4 extending out from the lower front side of the drying tank 2. A filter plate 5 is connected to the lower interior side of the drying tank 2. Plate 5 is located above jet pipe 4. A conical frame 6 is connected to the upper side of the inside of the drying tank 2. A condenser pipe 7 is connected to the conical frame 6. Both ends of the condenser pipe 7 extend out of the upper front side of the drying tank 2. A rotating rod 8 is rotatably connected to the middle of the inside of the drying tank 2. A cavity is opened on the upper side of the inside of the rotating rod 8. A wiper frame 9 is connected to the upper part of the rotating rod 8, and the wiper frame 9 contacts the bottom of the conical frame 6. A water channel 901 is spaced apart circumferentially on the wiper frame 9. A water storage box 10 is connected to the upper part of the rotating rod 8. The water storage box 10 is located below the wiper frame 9. A vertical pipe 11 is spaced apart circumferentially on the lower part of the wiper frame 9. The vertical pipe 11 is located inside the water storage box 10, and the upper end of the vertical pipe 11 is connected to the water channel 901. The drying tank 2 is provided with a rotating assembly for driving the rotating rod 8 to rotate. The drying tank 2 is provided with a drain assembly for draining the liquid in the water storage box 10.

[0030] like Figure 2 As shown, the rotating assembly includes a first motor 12, a first gear 13, and a second gear 14. The first motor 12 is installed on the top left side of the drying tank 2. The first gear 13 is connected to the output shaft of the first motor 12. The second gear 14 is connected to the upper part of the rotating rod 8, and the second gear 14 meshes with the first gear 13.

[0031] like Figure 2 and Figure 5 As shown, the drainage assembly includes a fixed base 15, a water suction pipe 1501, and a liquid level sensor 16. The fixed base 15 is connected to the top center of the drying tank 2, and the upper end of the rotating rod 8 is rotatably connected to the fixed base 15. The water suction pipe 1501 is connected to the fixed base 15, and the lower end of the water suction pipe 1501 is located in the cavity on the upper side of the rotating rod 8. The liquid level sensor 16 is installed on the upper side of the inside of the rotating rod 8. Square holes 17 are spaced apart circumferentially on the upper part of the rotating rod 8, and the square holes 17 are located inside the water storage box 10.

[0032] When the water-reducing agent needs to be dried, first install the device in the designated location, then connect the condenser pipe 7 to external condensate water to allow the condensate water to circulate within the condenser pipe 7, and connect the water pump to external pumping pipe 1501. Then, open the electric valve at the feed inlet of drying tank 2 and put an appropriate amount of water-reducing agent into drying tank 2 through the feed inlet, allowing the water-reducing agent to fall onto the top of filter plate 5. Then, close the electric valve at the feed inlet of drying tank 2, and then connect hot air to the jet pipe 4 so that the jet pipe 4 can spray hot air from bottom to top inside drying tank 2. The hot air will blow the water-reducing agent on filter plate 5 up. The blown-up water-reducing agent will separate into layers due to its own weight, i.e., smaller layers... The granular water-reducing agent will be on the upper layer, while larger granules or those that have adhered together will be on the lower layer. Hot air will dry the water-reducing agent, and the resulting water vapor will be discharged through exhaust pipe 3. Water vapor that is not discharged in time will accumulate at the bottom of the conical frame 6. This water vapor will come into contact with the condenser pipe 7, which carries condensate, and condense into water droplets that adhere to the bottom of the conical frame 6. At this point, the first motor 12 can be started. The first motor 12 drives the first gear 13 to rotate, which in turn drives the second gear 14 to rotate. The second gear 14 then drives the rotating rod 8 to rotate, which in turn drives the wiper frame 9. When rotated, the scraper 9 scrapes off water droplets adhering to the bottom of the conical frame 6, causing them to fall into the water inlet channel 901 and then into the vertical pipe 11, eventually falling into the water storage box 10. Water in the storage box 10 can enter the cavity on the upper side of the rotating rod 8 through the square hole 17. The liquid level sensor 16 monitors the liquid level in the cavity in real time. When the liquid level sensor 16 detects that the liquid level in the cavity is higher than a preset value, it sends a signal. Upon receiving the signal, the main controller controls the water pump to extract water from the cavity through the water pumping pipe 1501. When the liquid level is lower than the preset value, the liquid level sensor 16 will send a signal. After receiving the signal, the main controller will control the water pump to stop working. This ensures that the liquid level in the cavity is always higher than the square hole 17, thus preventing water vapor in the drying tank 2 from being directly discharged out through the square hole 17 and the water pumping pipe 1501. After the water-reducing agent is dried, the first motor 12 can be turned off to stop the rotating rod 8 from rotating and the jet pipe 4 can be controlled to stop spraying hot air. Then, the electric valve at the discharge port of the drying tank 2 can be opened to discharge the dried water-reducing agent out through the discharge port for easy collection by staff. Finally, the electric valve at the discharge port of the drying tank 2 can be closed.

[0033] like Figure 6As shown, it also includes a striking assembly, which includes a drive motor 18, a full gear 19, a rotating gear ring 20, and elastic ropes 21. The drive motor 18 is installed in the middle of the right side of the drying tank 2. The full gear 19 is connected to the output shaft of the drive motor 18. The rotating gear ring 20 is rotatably connected to the middle of the inner side of the drying tank 2, and the rotating gear ring 20 meshes with the full gear 19. Multiple elastic ropes 21 are circumferentially connected to the inner wall of the rotating gear ring 20.

[0034] When the device is drying the water-reducing agent, the drive motor 18 can be started. The drive motor 18 can drive the full gear 19 to rotate. The full gear 19 can drive the rotating gear ring 20 and the elastic rope 21 to rotate. The elastic rope 21 can beat the larger water-reducing agent particles in the lower layer, thereby breaking the larger water-reducing agent particles into smaller particles and accelerating the overall drying efficiency.

[0035] like Figures 6-10 As shown, it also includes a connecting cylinder 22, scrapers 23, actuating frame 24, and a moving mechanism. The lower part of the rotating rod 8 is connected to the connecting cylinder 22, which rotatably passes through the middle of the filter plate 5. Three scrapers 23 are circumferentially connected to the outer wall of the connecting cylinder 22, and the bottom of the scrapers 23 contacts the top of the filter plate 5. Actuating frame 24 is slidably connected to each of the three scrapers 23. The connecting cylinder 22 is provided with a moving mechanism for driving the actuating frame 24 to move. The moving mechanism includes a bevel gear ring 25, a bevel gear 26, a rotating rod 27, a pulley assembly 28, a connecting ring 29, and ball bearings 2901. The inner bottom of the drying tank 2 is connected to the bevel gear ring. 25. Three bevel gears 26 are rotatably connected to the lower part of the inner wall of the connecting cylinder 22 at intervals. All three bevel gears 26 mesh with the bevel gear ring 25. Three rotating rods 27 are rotatably connected to the upper part of the outer wall of the connecting cylinder 22 at intervals. Each rotating rod 27 corresponds to one of the bevel gears 26, and each of the three rotating rods 27 has an elliptical groove 2701 spaced apart. The bevel gears 26 and the rotating rods 27 are driven by a pulley assembly 28. Four connecting rings 29 are rotatably connected to the upper part of the inner side of the three actuating frames 24 at intervals. Each connecting ring 29 has a ball bearing 2901 rotatably connected to its inner wall, and the ball bearing 2901 rolls in the elliptical groove 2701.

[0036] When the rotating rod 8 rotates, it drives the connecting cylinder 22 and the scraper 23 to rotate. The scraper 23 scrapes the water-reducing agent on the filter plate 5 and pushes the water-reducing agent accumulated at the edge of the filter plate 5 towards the center, thus ensuring uniform drying of the water-reducing agent. At the same time, the connecting cylinder 22 drives the bevel gear 26 to rotate around the bevel gear ring 25. The bevel gear ring 25 drives the bevel gear 26 to rotate. The bevel gear 26 drives the rotating rod 27 to rotate through the pulley assembly 28. The rotating rod 27 drives the connecting ring 29 and the agitator 24 to reciprocate along the axial direction of the rotating rod 27 through the cooperation of the elliptical groove 2701 and the ball 2901. The agitator 24 can initially disperse larger particles of water-reducing agent to prevent them from clogging the filter plate 5.

[0037] like Figure 1 , Figure 11 and Figure 12 As shown, it also includes a storage frame 30, a connecting pipe 31, a screw rod 32, a second motor 33, a third gear 34, a fourth gear 35, and a preheating mechanism. The storage frame 30 is connected to the top left side of the base plate 1, and the connecting pipe 31 is connected to the right side of the storage frame 30. The lower left side of the connecting pipe 31 is connected to and maintains communication with the bottom right side of the storage frame 30. The upper right side of the connecting pipe 31 is connected to and maintains communication with the feed inlet of the drying tank 2. The screw rod 32 is rotatably connected inside the connecting pipe 31. The second motor 33 is installed on the upper right side of the storage frame 30, and the output shaft of the second motor 33 is connected to the third gear 34. The upper end of the rotating shaft of the screw rod 32 is connected to the gear 34 and the fourth gear 35 meshes with the third gear 34. The connecting pipe 31 is provided with a preheating mechanism for preheating the water-reducing agent conveyed by the screw rod 32. The preheating mechanism includes a fixed pipe 36, a preheating pipe 37 and an L-shaped rotating pipe 38. The lower part of the connecting pipe 31 is connected to the fixed pipe 36. The screw rod 32 is connected to the preheating pipe 37. The upper and lower ends of the preheating pipe 37 are connected to the L-shaped rotating pipe 38 and kept in communication. The other ends of the two L-shaped rotating pipes 38 are connected to the fixed pipe 36 and the exhaust pipe 3 respectively and kept in communication.

[0038] Initially, the storage box 30 contains a suitable amount of water-reducing agent. Some of the water-reducing agent in the storage box 30 will fall into the connecting pipe 31 due to gravity. When it is necessary to add water-reducing agent to the drying tank 2, the second motor 33 drives the third gear 34 to rotate. The third gear 34 drives the fourth gear 35 to rotate, and the fourth gear 35 drives the screw rod 32 to rotate. The screw rod 32 can transport the water-reducing agent in the connecting pipe 31 upwards and add it through the feed inlet of the drying tank 2. The water-reducing agent is added to the drying tank 2, which enables automatic feeding of the water-reducing agent and controls the feeding rate of the water-reducing agent. At the same time, the water vapor discharged from the exhaust pipe 3 can enter the preheating pipe 37 through the upper L-shaped rotating pipe 38. The water vapor in the preheating pipe 37 can preheat the water-reducing agent in the connecting pipe 31 to prevent the low-temperature water-reducing agent from clumping due to temperature difference when entering the high-temperature drying tank. Then, the water vapor in the preheating pipe 37 will be discharged downward through the lower L-shaped rotating pipe 38 and the fixed pipe 36.
