Description

Technical Field

[0001] This utility model relates to the field of resin granule storage technology, and in particular to a device that prevents material accumulation on the walls of a resin granule storage tank. Background Technology

[0002] Resin granule storage tanks are key equipment in the chemical and plastics processing industries. Their core function is to safely store resin granules and ensure material flowability, while preventing problems such as material accumulation, oxidation, and static electricity. In terms of structural design, vertical conical bottom tanks rely on gravity unloading, which is suitable for large-scale continuous production and drives the continuous evolution of resin storage towards high energy efficiency.

[0003] However, in the existing technology, resin granules often adhere to the tank wall during storage due to physical or chemical effects, such as changes in temperature and humidity, and inter-particle adhesion, forming a material accumulation layer. This accumulation occupies the effective storage space, reduces the utilization rate of the tank, and long-term accumulation of resin may deteriorate due to oxidation or moisture, contaminating subsequent production and reducing operational efficiency.

[0004] In response to this technical problem, this application proposes a device that prevents material accumulation on the wall of a resin granule storage tank. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device that prevents material accumulation on the walls of a resin granule storage tank. This device can break up and disperse agglomerated resin granules, thereby increasing the discharge flow rate of particles of different sizes, reducing the agglomeration rate, and significantly improving the discharge efficiency. The material is then pumped into the connecting ring through the input pipe, allowing the connecting ring to dry the storage hopper and prevent the resin granules from becoming damp and deteriorating.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A device for preventing material accumulation on the wall of a resin granule storage tank includes a storage silo. A material inlet is fixedly connected to the outer wall of the rear end of the storage silo and extends through it. A drive motor is fixedly connected to the outer wall of the top end of the storage silo. The drive end of the drive motor is connected to a support frame one and a support frame two via a bevel gear assembly. A stirring plate is rotatably connected to both ends of the left and right sides of the support frame two and both ends of the front and rear sides of the support frame one. A drying chamber is fixedly connected to the outer wall of the storage silo. A circulating fan is connected to the inner wall of the drying chamber via a drying assembly. An input pipe is fixedly connected to the bottom end of the drying chamber.

[0008] Furthermore, the bevel gear assembly includes a connecting rod fixedly connected to the top end of the second support frame, a connecting pipe fixedly connected to the top end of the first support frame, and the outer wall of the top end of the connecting rod sleeved on the inner wall of the connecting pipe.

[0009] Furthermore, bevel gear two is fixedly connected to the top of both the connecting pipe and the connecting rod, and bevel gear one is fixedly connected to the driving end of the drive motor. The bevel gear two and bevel gear one are meshed together.

[0010] Furthermore, an internal gear ring is fixedly connected to the top of the inner wall of the storage silo, and a transmission gear is fixedly connected to the top of the stirring plate at both ends of the support frame. The internal gear ring and the transmission gear are meshed together.

[0011] Furthermore, a fixed frame is fixedly connected to the bottom of the inner wall of the storage silo, and an adapter plate is rotatably connected to the top of the fixed frame.

[0012] Furthermore, the bottom ends of the stirring plates at both ends of the support frame 2 pass through the top end of the adapter plate and are fixedly connected to the transmission gear 2.

[0014] Furthermore, a connecting ring is fixedly connected to the bottom of the storage hopper and extends through it, an intercepting net is fixedly connected to the top of the connecting ring, and the bottom of the input pipe is fixedly connected to the outer wall of the connecting ring.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when the resin granules enter the storage silo through the feed inlet, the drive motor starts and, through the transmission of the bevel gear set, the connecting rod and the connecting pipe rotate synchronously in opposite directions, respectively driving the second support frame and the first support frame to perform planetary revolution. The four sets of stirring plates rotate around the axis of the silo body under the drive of the support frame, and at the same time, through the meshing of the internal gear ring and the transmission gear, they achieve reverse or same-direction rotation, forming a compound motion of revolution and rotation, which can break and disperse the agglomerated resin granules, increase the discharge flow rate of the granules of different sizes, reduce the agglomeration rate, and significantly improve the discharge efficiency.

[0017] 2. In this utility model, by starting the circulating fan, the circulating fan filters the material through the screen and then passes through the intermittently arranged partition plates into the drying chamber. The low temperature generated by the heating wire forms hot air, which is poured into the connecting ring through the input pipe, so that the connecting ring dries the material in the storage chamber and prevents the resin granules from getting damp and deteriorating.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 and Figure 3This utility model provides an embodiment of a device for preventing material accumulation on the wall of a resin granule storage tank. The device includes a storage silo 1, with a material inlet 5 fixedly connected to the outer wall of the rear end of the silo 1 and extending through it. A drive motor 6 is fixedly connected to the outer wall of the top end of the silo 1. The drive end of the drive motor 6 is connected to a support frame 12 and a support frame 23 via a bevel gear assembly. Stirring plates 14 are rotatably connected to the left and right ends of the support frame 23 and the front and rear ends of the support frame 12. The bevel gear assembly includes a connecting rod 10 fixedly connected to the top end of the support frame 23 and a connecting pipe 11 fixedly connected to the top end of the support frame 12. The outer wall of the top end of the connecting rod 10 is sleeved on the inner wall of the connecting pipe 11. Bevel gears are fixedly connected to the top ends of both the connecting pipe 11 and the connecting rod 10. 29. A bevel gear 8 is fixedly connected to the drive end of the drive motor 6. The bevel gear 9 and the bevel gear 8 are meshed. An internal gear ring 19 is fixedly connected to the top of the inner wall of the storage silo 1. A transmission gear 20 is fixedly connected to the top of the stirring plates 14 at both ends of the support frame 12. The internal gear ring 19 and the transmission gear 20 are meshed. A fixed frame 15 is fixedly connected to the bottom of the inner wall of the storage silo 1. A transition plate 16 is rotatably connected to the top of the fixed frame 15. The bottom of the stirring plates 14 at both ends of the support frame 13 passes through the top of the transition plate 16 and is fixedly connected to the transmission gear 21. An internal gear ring 22 is fixedly connected to the inner wall of the fixed frame 15. The transmission gear 21 and the internal gear ring 22 are meshed.

[0026] Specifically: After the resin granules are conveyed into the storage silo 1 through the feed inlet 5, the operator starts the drive motor 6 and transmits the power to the orthogonal bevel gear pair composed of bevel gear 8 and bevel gear 9 through the coupling 7. The transmission ratio is designed to be 1:1.5, which can realize the 90° rotation between the input shaft and the output shaft and the torque amplification function. During this process, the bevel gear pair drives the connecting rod 10 and the connecting pipe 11 to rotate synchronously in opposite directions. The connecting rod 10 is fixed to the central shaft of the support frame 13 by flange bolts, while the connecting pipe 11 is dynamically connected to the support frame 12 through a spline structure. When the two support frames rotate, they drive four sets of circumferentially distributed stirring plates 14 to perform planetary motion along the inner wall of the storage bin 1. At the same time, the stirring plates 14 achieve rotation through two sets of independent gear systems. The outer rotation mechanism is that the internal gear ring 19 fixed to the support frame 12 meshes with the transmission gear 20 at the end of the stirring plate shaft with a module m=2 and a gear ratio of 3:1, driving the stirring plate to rotate at an angular velocity of about 5-10 rpm in the opposite direction to the rotation direction of the support frame. The inner rotation mechanism is that the transmission gear 21 installed on the support frame 21 meshes with the internal gear ring 22 fixed at the bottom of the bin, causing the stirring plate on this side to generate a co-directional enhanced rotation. This composite motion mode causes the stirring plate 14 to form a three-dimensional turbulent field under the combined action of centrifugal force and shear force. The polyurethane antistatic scraper strip set on its edge can effectively peel off the resin particles attached to the bin wall, while the serrated stainless steel plate breaks up the agglomerated particles.

[0027] Reference Figure 2 and Figure 4 A drying chamber 2 is fixedly connected to the outer wall of the storage silo 1. A circulating fan 17 is connected to the inner wall of the drying chamber 2 through a drying assembly. An input pipe 4 is fixedly connected to the bottom of the drying chamber 2. The drying assembly includes a connecting frame 7 fixedly connected to the right end of the drying chamber 2. A screen 3 is fixedly connected to the right end of the connecting frame 7. A partition plate 25 is fixedly connected to the left end of the connecting frame 7. A heating wire 18 is fixedly connected to the bottom of the inner wall of the drying chamber 2. A connecting ring 23 is fixedly connected to the bottom of the storage silo 1 and passes through it. An intercepting net 24 is fixedly connected to the top of the connecting ring 23. The bottom of the input pipe 4 is fixedly connected to the outer wall of the connecting ring 23.

[0028] Specifically: After the resin granules are stirred and dispersed, the operator starts the circulating fan 17. This fan uses a high-temperature resistant EC backward-inclined centrifugal impeller to drive the airflow through a three-stage filtration system. First, it passes through a 316L stainless steel sintered screen 3 with a pore size ≤50μm to intercept dust and foreign objects. Then, it passes through the V-shaped staggered partition plates 25 in the drying chamber 2, with a plate spacing of 80mm and a guide angle of 30°. By extending the airflow path, the airflow is evenly distributed. At the same time, the nickel-chromium alloy heating wire 18 embedded in the inner wall of the drying chamber operates in a low-temperature heating mode of 40-60℃ under the control of the PID temperature control module, heating the filtered air to above the dew point temperature to form dry hot air with a humidity ≤5%RH. The hot air is delivered to the annular porous distributor 23 via the insulated glass fiber inlet pipe 4. The distributor adopts a double-layer annular cavity design with 72 Φ6mm guide holes inside. It sprays laminar hot air onto the inner wall of the storage silo 1 at a wind speed of 0.5-1.2m / s. Combined with the PTFE hydrophobic coating in the silo jacket, it achieves dynamic humidity balance in the silo. During this process, the circulating fan achieves closed-loop control through the differential pressure sensor and temperature and humidity transmitter to ensure that the drying energy consumption is stable at 0.5-0.8kW·h / ton of resin, and to avoid yellowing or degradation of resin particles due to local overheating.

[0029] Working principle: After the resin granules are conveyed into the storage silo 1 through the feed inlet 5, the drive motor 6 is started to drive the bevel gear 8 to transmit power to the bevel gear 9, thereby causing the connecting rod 10 and the connecting pipe 11 to rotate synchronously in opposite directions. The connecting rod 10 drives the support frame 13, and the connecting pipe 11 drives the support frame 12 to rotate, thereby causing the stirring plate 14 connected to the support frame 12 and the support frame 13 to rotate in a circular motion. While the stirring plate 14 is rotating in a circular motion, it is driven by the internal gear ring 19 and the transmission gear 20, as well as the transmission gear 21 and the transmission gear 20. The internal gear ring 22 drives the four sides of the stirring plate 14 to rotate, thereby dispersing the resin granules in the storage bin 1, preventing the resin granules from clumping and facilitating their discharge. The circulating fan 17 is started, so that the granules are filtered through the screen 3 and then pass through the intermittently arranged partition plates 25 into the drying bin 2. The low temperature generated by the heating wire 18 forms hot air, which is poured into the connecting ring 23 through the input pipe 4, so that the connecting ring 23 dries the contents of the storage bin 1 and prevents the resin granules from getting damp and deteriorating.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
