Description

Technical Field

[0001] This utility model relates to the field of early strength agent production technology, specifically to a drying equipment for early strength agent production. Background Technology

[0002] Early strength agents typically contain a variety of chemical components, which are prone to absorbing moisture in humid environments, leading to clumping or deterioration. This affects the product's performance and storage stability. Therefore, drying is necessary to remove moisture from the early strength agent, preventing it from absorbing moisture and deteriorating during storage and transportation, thus ensuring the product's quality and stability.

[0003] Most existing early-strength agent drying devices use a hot air blower to input hot air into the drying chamber during drying, and then use a stirring mechanism to agitate the early-strength agent. However, the early-strength agent often accumulates inside the drying chamber, and even with a stirring mechanism, it is difficult to fully disperse the early-strength agent. Consequently, the early-strength agent is still prone to uneven heating, and incomplete drying requires a longer time to reach the standard. At the same time, dehumidification is required in the drying chamber during drying. Due to the influence of hot air, some desiccant is easily discharged from the dehumidification pipe along with moisture, resulting in desiccant waste. Therefore, a filter screen is installed on the dehumidification pipe. However, desiccant adhering to the filter screen can easily cause blockage, resulting in slow moisture discharge and affecting drying efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a drying equipment for producing early strength agents, so as to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for producing an early-strength agent, comprising a base, a drying chamber and a hot air blower on the top of the base, a lifting cylinder inside the lower part of the drying chamber, and a return port and a discharge port on both sides of the lifting cylinder, respectively; multiple sets of sliding rods fixed between the inner wall of the drying chamber and the lifting cylinder, with sliding sleeves fitted onto the outer surface of the sliding rods; a material distribution screen on the top of the sliding sleeve; one side of the material distribution screen being fixed to the inner wall of the drying chamber by a spring; connecting rods fixed between the material distribution screens, and teeth fixed to the top of one set of material distribution screens by a fixing rod. The drying chamber has a rod, with a force-bearing plate fixed at one end of the rod. A motor is installed on the top of the drying chamber, and a drive shaft is connected to the output end of the motor. An eccentric wheel and a spiral blade are fixed on the outer surface of the drive shaft. The air outlet section of the hot air blower is connected to a hot air pipe through a three-way connector. One side of the hot air pipe is connected to a multi-component gas pipe. Exhaust pipes pass through both sides of the drying chamber, and a filter screen is installed inside the exhaust pipe. A mounting bracket is fixed at the top inside the drying chamber, and a connecting shaft is installed on the inner side of the mounting bracket. A collision ball is connected to the outer surface of the connecting shaft through a connecting rope. A gear is fixed at the bottom end of the connecting shaft.

[0006] Furthermore, the drying oven has sealing boxes on both sides of its inner wall, and both the gear and the rack are displaced inside the sealing boxes, with the rack slidably connected to the sealing boxes.

[0007] By adopting the above technical solution, with the cooperation of the sealed box, dust can adhere to the gears and racks, thereby affecting the stability of the gear and rack meshing.

[0008] Furthermore, a control panel is installed in the middle of the outer surface of the drying oven, and the hot air blower and motor are electrically connected to the control panel.

[0009] By adopting the above technical solution, staff can easily control the motor and hot air blower through the control panel.

[0010] Furthermore, the top of the drying chamber is provided with a feeding port, and the lower part of the outer surface of the drying chamber is provided with a sealing door.

[0011] By adopting the above technical solution, the staff can easily add the early strength agent into the drying chamber through the feeding port. After the early strength agent has dried, the staff can open the sealed door and discharge the early strength agent.

[0012] Furthermore, a guide plate is provided at the bottom of the interior of the drying chamber, and the top of the guide plate is inclined towards the return port.

[0013] By adopting the above technical solution, the early strength agent can be concentrated towards the return port under the action of the guide plate.

[0014] Furthermore, the spring is provided in several groups, and all groups of springs are made of high manganese steel.

[0015] By adopting the above technical solutions, high-manganese steel materials have strong toughness, better restoring properties, and good heat resistance, thus preventing the spring from being in a high-temperature environment for a long time, which would affect its performance and service life.

[0016] Furthermore, the top of the air distribution pipe is provided with several nozzles, and several groups of nozzles are distributed at equal intervals.

[0017] By adopting the above technical solution, air can be blown upwards through several sets of equally spaced nozzles, which can reduce the falling speed of the early strength agent and make the drying more thorough.

[0018] Furthermore, the collision balls are provided in several groups, and all groups of collision balls are made of rubber material.

[0019] By adopting the above technical solution, several sets of rubber material collision balls can knock on the filter screen, thereby causing the filter screen to vibrate. This avoids clogging of the filter screen, and the rubber material is flexible and will not damage the filter screen.

[0020] In summary, the present invention has the following main advantages:

[0021] 1. This utility model comprises a lifting cylinder, a spiral blade, a distribution screen, a spring, a toothed rod, a fixed rod, a sliding rod, a sliding sleeve, and a connecting rod. When drying the early-strength agent, the motor rotates, causing the drive shaft to rotate, which in turn causes the spiral blade to rotate. The early-strength agent enters the lifting cylinder through the return port and is then discharged from the discharge pipe. The discharged early-strength agent falls onto the distribution screen. The rotation of the drive shaft causes the eccentric wheel to rotate, and the eccentric wheel intermittently squeezes the force plate, thereby displacing the toothed rod. Under the action of the fixed rod and the connecting rod, the multi-component distribution screen is driven to move on the sliding rod through the sliding sleeve. In conjunction with the spring, the multi-component distribution screen vibrates back and forth, causing the early-strength agent on the distribution screen to fall downwards one by one, thus ensuring that the early-strength agent is evenly dispersed. Furthermore, the hot air blows from bottom to top, which reduces the falling speed of the early-strength agent, allowing the dry-strength agent to fully contact the hot air. This avoids uneven dispersion of the early-strength agent, which would affect the drying effect, and also improves the drying efficiency.

[0022] 2. This utility model is equipped with gears, connecting shafts, connecting ropes, and impact balls. When the rack moves left or right, it drives the gears to rotate. The rotation of the gears causes the connecting shaft to rotate, which in turn causes the connecting rope to drive the impact balls to rotate. The rotation of the impact balls can knock the filter screen, causing the filter screen to vibrate. During the vibration, the early-strength agent on the filter screen can be shaken off, thus preventing the early-strength agent from adhering to the filter screen and clogging it, which would affect the moisture discharge speed. It is highly practical. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] Example 1: A drying equipment for producing early strength agents, such as... Figures 1-6As shown, the system includes a base 1, with a drying chamber 2 and a hot air blower 3 on top of the base 1. The drying chamber 2 has a feeding port 8 on top and a sealing door 6 on the lower outer surface. Workers can easily add an early-strength agent into the drying chamber 2 through the feeding port 8. After the early-strength agent has dried, workers can open the sealing door 6 to discharge it. A lifting cylinder 13 is located at the lower interior of the drying chamber 2, with a return port 31 and a discharge port 14 on each side. Multiple sets of sliding rods 16 are fixed between the inner wall of the drying chamber 2 and the lifting cylinder 13. Sliding sleeves 17 are fitted onto the outer surface of each sliding rod 16. A material distribution screen 19 is located on the top of each sliding sleeve 17. One side of the material distribution screen 19 is fixed to the inner wall of the drying chamber 2 by a spring 18. Connecting rods 20 are fixed between the material distribution screens 19, and a toothed rod 23 is fixed to the top of one set of material distribution screens 19 by a fixing rod 22. A force-bearing plate 24 is fixed to one end of the toothed rod 23. The top of the box 2 is equipped with a motor 9, and the output end of the motor 9 is connected to a drive shaft 10. An eccentric wheel 21 and a spiral blade 15 are fixed on the outer surface of the drive shaft 10. The air outlet section of the hot air blower 3 is connected to a hot air pipe 4 through a three-way connector. One side of the hot air pipe 4 is connected to a multi-component gas pipe 5. Exhaust pipes 32 pass through both sides of the drying box 2, and a filter screen 29 is installed inside the exhaust pipe 32. A mounting bracket 12 is fixed on the upper part of the interior of the drying box 2, and a connecting shaft 25 is installed on the inner side of the mounting bracket 12. The outer surface of the connecting shaft 25 is connected to a collision ball 27 through a connecting rope 26. There are several sets of collision balls 27, and all sets of collision balls 27 are made of rubber material. The several sets of rubber collision balls 27 can knock on the filter screen 29, thereby causing the filter screen 29 to vibrate. This avoids clogging of the filter screen 29. In addition, the rubber material is flexible and will not damage the filter screen 29. A gear 28 is fixed at the bottom end of the connecting shaft 25.

[0033] See Figure 1 In the above embodiment, a control panel 7 is installed in the middle of the outer surface of the drying oven 2. The hot air blower 3 and the motor 9 are both electrically connected to the control panel 7, and the operator can easily control the motor 9 and the hot air blower 3 through the control panel 7.

[0034] See Figure 2 In the above embodiment, a guide plate 30 is provided at the bottom of the interior of the drying box 2, and the top of the guide plate 30 is inclined towards the return port 31. Under the action of the guide plate 30, the early strength agent can be gathered towards the return port 31.

[0035] See Figures 2-4In the above embodiments, the spring 18 is provided in several groups, and the spring 18 in several groups is made of high manganese steel. High manganese steel has strong toughness, stronger restoring ability, and good heat resistance, so as to avoid the spring 18 being in a high temperature environment for a long time, which would affect its performance and service life.

[0036] See Figure 2 In the above embodiment, the top of the air distribution pipe 5 is provided with a plurality of nozzles, and the plurality of groups of nozzles are equidistantly distributed. The plurality of groups of equidistantly distributed nozzles can blow air upward, which can reduce the speed at which the early strength agent falls, so as to make the drying more thorough.

[0037] Example 2: To avoid the early-strength agent powder affecting the meshing of gears and racks, Example 2 is an improvement on Example 1. (See attached document for details.) Figure 2 and Figure 4 The drying oven 2 has sealing boxes 11 on both sides of its inner wall, and the gear 28 and the rack 23 are both displaced inside the sealing boxes 11. The rack 23 is slidably connected to the sealing boxes 11. With the cooperation of the sealing boxes 11, dust can adhere to the gear 28 and the rack 23, thereby affecting the stability of the meshing of the gear 28 and the rack 23.

[0038] The implementation principle of this utility model is as follows: First, the operator adds the desiccant into the drying chamber 2, and then starts the motor 9 and the hot air blower 3. The rotation of the motor 9 causes the drive shaft 10 to rotate, which in turn causes the spiral blade 15 to rotate. The early-strength agent enters the lifting cylinder 13 through the return port 31 and is then discharged from the discharge pipe. The discharged early-strength agent falls onto the distribution screen 19. The rotation of the drive shaft 10 causes the eccentric wheel 21 to rotate. The eccentric wheel 21 intermittently squeezes the force plate 24, thereby displacing the toothed rod 23. Then, under the action of the fixed rod 22 and the connecting rod 20, it drives the multi-component distribution screen 19 to move on the sliding rod 16 through the sliding sleeve 17. In conjunction with the spring 18, it can make... The multi-component sieve 19 vibrates back and forth, causing the early-strength agent on the sieve 19 to fall downwards one by one, thus ensuring that the early-strength agent is evenly dispersed. The hot air blows from bottom to top, which reduces the falling speed of the early-strength agent, allowing the dry-strength agent to fully contact the hot air. When the toothed rod 23 moves left and right, it drives the gear 28 to rotate. The rotation of the gear 28 causes the connecting shaft 25 to rotate, which in turn causes the connecting rope 26 to drive the collision ball 27 to rotate. The rotation of the collision ball 27 can knock the filter screen 29, causing the filter screen 29 to vibrate. During the vibration, the early-strength agent on the filter screen 29 can be shaken off, thus preventing the early-strength agent from adhering to the filter screen 29 and clogging it, which would affect the moisture discharge speed.
