Description

Technical Field

[0001] This application relates to the fields of industrial automation and materials processing technology, and in particular to an apparatus for particle polishing and forming. Background Technology

[0002] Granule polishing and forming equipment is a specialized device used to improve the surface smoothness, shape consistency and physical properties of granules. It has broad application prospects in pharmaceutical, chemical, food, agriculture and new energy fields. It is usually integrated into the later stage of the granulation process to refine the rough granules formed in the initial granulation. The device significantly improves the flowability of granules during polishing, as well as the stability and end performance after polishing.

[0003] In the prior art, the particle polishing and forming device includes a granulator, a powder tank, a discharge pipe, a water storage tank, a water supply pipe, and an infrared lamp. One end of the discharge pipe is connected to the powder tank, and the other end is installed inside the granulator. One end of the water supply pipe is connected to the water storage tank, and the other end is installed inside the granulator. The granulator is used to granulate the added powder and water. The infrared lamp is installed on the granulator to heat the particles inside the granulator. When granulation is required, the discharge pipe and the water supply pipe are opened, and the powder and water are added to the granulator for granulation. After granulation, the infrared lamp is turned on to heat the granulated particles, causing the particles to soften in a controllable manner. Under the action of the granulator, the particles are shaped and polished, thereby achieving surface smoothing and shape regularization of the particles.

[0004] Regarding the aforementioned technologies, the infrared lamps have poor overall sealing, and dust during the granulation process may enter the infrared lamps, causing damage and posing a safety hazard. Furthermore, infrared lamps rely on radiative heat transfer, and differences in material surface roughness or color may result in slow heating and prevent the moisture inside the particles from evaporating quickly, making it difficult for the particles to reach the softened state required for shaping and polishing. Therefore, improvements are needed to address these issues. Utility Model Content

[0005] In order to avoid dust entering the infrared lamp device during use and causing safety hazards, and to enable the particles to quickly reach the softened state required for shaping and polishing, this application provides a device for particle polishing and shaping.

[0006] The device for particle polishing and forming provided in this application adopts the following technical solution:

[0007] A granulation polishing and forming apparatus includes a granulator, a powder tank, and a water storage tank. The powder tank is positioned above the granulator, and the water storage tank is positioned to one side of the granulator. The powder tank has a discharge pipe, with one end of the discharge pipe away from the powder tank located inside the granulator. The water storage tank has a water outlet pipe, with one end of the water outlet pipe away from the water storage tank located inside the granulator. A water pump is installed between the granulator and the water storage tank. The end of the water outlet pipe near the water storage tank is connected to the water outlet of the water pump, and the water inlet of the water pump is connected to the water storage tank. A heating mechanism is provided on one side of the granulator for outputting hot air to heat the un-shaped and polished granules inside the granulator.

[0008] By adopting the above technical solution, the granulator, discharge pipe, and water pump are opened simultaneously. The powder in the powder tank and the water in the water storage tank enter the granulator for granulation. When the granules in the granulator need to be shaped and polished, the heating mechanism in this application outputs hot air to heat the granules in the granulator. Compared with the infrared radiation heating used in the prior art, the hot air output by the heating mechanism can improve the heat exchange effect between the hot air and the granules and the heating is more uniform when it flows. The flow of hot air can also increase the speed of moisture evaporation and escape in the granules, so that the granules can quickly achieve the softening effect required for processing, which facilitates the granulator to shape and polish the granules. The more uniform heating of the granules can also improve the plastic polishing effect of the granules. The heating mechanism does not directly contact the working space inside the granulator, avoiding the impact of dust on the device and improving the safety of the device.

[0009] Optionally, the heating mechanism includes an electric heating box, a heating tube, a thermocouple, a primary filter, a secondary filter, and a hot air output assembly. The electric heating box is located on one side of the granulator, with an air inlet and an air outlet at each end. The heating tube is located inside the electric heating box to heat the air entering the box. Two sets of thermocouples are provided, one inside the electric heating box and the other near the air outlet. The thermocouples can detect the temperature inside the electric heating box and at the air outlet, respectively. The primary and secondary filters are both located at the air inlet, with the primary filter located on the side of the secondary filter furthest from the air outlet. The hot air output assembly is located at the air outlet of the electric heating box and is used to deliver the heated air to the granulator.

[0010] By adopting the above technical solution, the electric heating box is started, and the heating tube heats the air inside the electric heating box. Thermocouples detect the temperature inside the electric heating box and at the air outlet. When the set temperature is reached, the hot air output component delivers the heated air to the granulator to heat the granules. The flowing hot air fully heats the granules and causes the moisture inside the granules to evaporate quickly, so that the granules quickly reach the required softening state, thereby improving the shaping and polishing effect of the granules. The primary and secondary filter cotton can prevent dust from entering the electric heating box and avoid damaging the electric heating box and causing safety hazards.

[0011] Optionally, the hot air output assembly includes a centrifugal fan, a main air duct, branch air ducts, a hot air valve, and a universal joint air duct. The air inlet of the centrifugal fan is connected to the air outlet of the electric heating box. One end of the main air duct is connected to the air outlet of the centrifugal fan, and the other end of the main air duct is closed. The branch air duct is installed on the main air duct, the hot air valve is installed on the branch air duct, and the universal joint air duct is installed at the end of the branch air duct away from the main air duct. The side of the universal joint air duct away from the branch air duct can be rotated into the granulator.

[0012] By adopting the above technical solution, when the temperature inside the electric heating box and the air outlet reaches the set temperature, the centrifugal fan is started and the hot air valve is opened. At the same time, the universal joint air duct is turned into the granulator. The centrifugal fan transports the air that has been heated in the electric heating box to the granulator through the main air duct and the branch air duct, thereby achieving full heating of the granules with hot air at a constant temperature. The hot air with kinetic energy can also make the moisture in the granules evaporate quickly, so that the granules quickly reach the required softening state. The universal joint air duct can change shape, so that the position and angle can be adjusted according to the needs.

[0013] Optionally, a drive motor is provided at the end of the powder tank near the discharge pipe, and a spiral blade is provided on the output end of the drive motor.

[0014] By adopting the above technical solution, the drive motor is started, which drives the spiral blades to rotate. The rotation of the spiral blades transports the powder in the powder tank to the granulator along the discharge pipe. During the spiral conveying process, the powder will be turned over to reduce agglomeration, thereby achieving uniform addition of powder into the granulator and improving the subsequent shaping and polishing effect. In addition, the drive motor can be adjusted according to the granulation requirements to control the powder discharge rate.

[0015] Optionally, a solenoid valve and a pressure gauge are installed on the water outlet pipe.

[0016] By adopting the above technical solution, when granulation is required, the solenoid valve is opened, allowing water in the water storage tank to enter the granulator through the water outlet pipe. The pressure gauge on the water outlet pipe can provide real-time feedback on the water pressure in the water outlet pipe, which facilitates the control of the water flow rate in the water outlet pipe.

[0017] Optionally, a metal-shaped flexible hose is provided at the end of the water outlet pipe near the granulator.

[0018] By adopting the above technical solution, the height and angle of the metal shaping hose can be adjusted according to requirements during granulation.

[0019] Optionally, the heating tubes are arranged in multiple U-shapes, and multiple sets of heating tubes are arranged at intervals in height.

[0020] By adopting the above technical solution, multiple sets of U-shaped heating tubes can increase the contact area with air and improve the heating efficiency of air.

[0021] Optionally, a control cabinet is provided on one side of the granulator for coordinating and centrally controlling the operation of the granulator, the drive motor, the solenoid valve, the electric heating box, the centrifugal fan, and the thermocouple.

[0022] By adopting the above technical solutions, the control cabinet can coordinate and centrally control the granulator, drive motor, solenoid valve, electric heating box, centrifugal fan and thermocouple, thereby reducing labor costs and improving production efficiency.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The heating mechanism in this application does not directly contact the working space inside the granulator, and when the heating mechanism is working, the primary filter cotton and the secondary filter cotton can prevent dust from entering the electric heating box, thus avoiding damage to the electric heating box and causing safety hazards.

[0025] 2. The heating mechanism in this application can quickly bring the particles to the softened state required for shaping and polishing. The electric heating box is started, and the heating tube heats the air inside the electric heating box. Thermocouples detect the temperature inside the electric heating box and at the air outlet. When the set temperature is reached, the centrifugal fan is started and the hot air valve is opened. At the same time, the universal joint air duct is turned into the granulator. The centrifugal fan transports the heated air in the electric heating box to the granulator through the main air duct and branch air ducts. The flowing hot air fully heats the particles, causing the moisture in the particles to evaporate quickly and the particles to quickly reach the required softened state, thereby improving the shaping and polishing effect of the particles.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses an apparatus for particle polishing and forming, referring to... Figure 1 and Figure 2 The system includes a granulator 1, a powder tank 2, and a water storage tank 3. The powder tank 2 is fixedly installed above the granulator 1, and the water storage tank 3 is fixedly installed on one side of the granulator 1. A discharge pipe 21 is welded to the powder tank 2, and the end of the discharge pipe 21 away from the powder tank 2 is installed inside the granulator 1. A water outlet pipe 31 is welded to the water storage tank 3, and the end of the water outlet pipe 31 away from the water storage tank 3 is installed inside the granulator 1. A water pump 32 is fixedly installed between the granulator 1 and the water storage tank 3. The end of the water outlet pipe 31 near the water storage tank 3 is connected to the water outlet of the water pump 32, and the water inlet of the water pump 32 is connected to the liquid storage tank. A heating mechanism 4 is installed on one side of the granulator 1.

[0035] Simultaneously, the granulator 1, discharge pipe 21, and water pump 32 are turned on. The powder in the powder tank 2 and the water in the water storage tank 3 enter the granulator 1 for granulation. When the granules in the granulator 1 need to be shaped and polished, the heating mechanism 4 of this application outputs hot air to heat the granules in the granulator 1. Compared with the infrared radiation heating used in the prior art, the hot air output by the heating mechanism 4 can improve the heat exchange effect between the hot air and the granules and the heating is more uniform when it flows. The flow of hot air can also improve the evaporation and escape of moisture in the granules. The speed of heating allows the particles to quickly reach the softening effect required for processing, facilitating the granulator 1 to shape and polish the particles. More uniform heating of the particles also improves the plastic polishing effect. The heating mechanism 4 does not directly contact the working space inside the granulator 1, avoiding the impact of dust on the device and improving the safety of the device. In this embodiment, the granulator 1, powder tank 2, and water outlet pipe 31 are all provided in multiple sets. The water storage tank 3 and the heating mechanism 4 can supply multiple sets of granulators 1, powder tank 2, and water outlet pipe 31 for use.

[0036] Reference Figure 2 and Figure 4 In existing technologies, infrared lamp radiation heating is used, but the surface roughness or color difference of the material may lead to slow heating. Therefore, the heating mechanism 4 in this embodiment includes an electric heating box 41, a heating tube 42, a thermocouple 43, a primary filter cotton 44, a secondary filter cotton 45, and a hot air output component 5. The electric heating box is installed on one side of the granulator 1. The electric heating box 41 has an air inlet and an air outlet at its two ends, respectively. The heating tube 42 is fixedly installed inside the electric heating box 41. Two sets of thermocouples 43 are installed, and the two sets of thermocouples 43 are fixedly installed inside the electric heating box 41 and at the end of the electric heating box 41 near the air outlet, respectively. The primary filter cotton 44 and the secondary filter cotton 45 can be detachably installed on the air inlet, and the primary filter cotton 44 can be detachably installed on the side of the secondary filter cotton 45 away from the air outlet. The hot air output component 5 is installed on the air outlet of the electric heating box 41.

[0037] The electric heating box 41 is started, and the heating tube 42 heats the air inside the electric heating box 41. Thermocouple 43 detects the temperature inside the electric heating box 41 and at the air outlet. When the set temperature is reached, the hot air output component 5 delivers the heated air to the granulator 1 to heat the granules. The flowing hot air fully heats the granules and causes the moisture inside the granules to evaporate quickly, so that the granules can quickly reach the required softening state, thereby improving the shaping and polishing effect of the granules. The primary filter cotton 44 and the medium-efficiency filter cotton 45 can prevent dust from entering the electric heating box 41 and avoid damaging the electric heating box 41 and causing safety hazards.

[0038] Reference Figure 2 and Figure 5In order to deliver the hot air in the electric heating box 41 to the granulator 1 to heat the particles, the hot air output component 5 in this embodiment includes a centrifugal fan 51, a main air duct 52, a branch air duct 53, a hot air valve 54, and a universal joint air duct 55. The air inlet of the centrifugal fan 51 is connected to the air outlet of the electric heating box 41. One end of the main air duct 52 is connected to the air outlet of the centrifugal fan 51, and the other end of the main air duct 52 is closed. The branch air duct 53 is welded to the main air duct 52. The hot air valve 54 is fixedly installed on the branch air duct 53. The universal joint air duct 55 is fixedly installed at the end of the branch air duct 53 away from the main air duct 52.

[0039] When the temperature inside the electric heating box 41 and the air outlet reaches the set temperature, the centrifugal fan 51 is started and the hot air valve 54 is opened. At the same time, the universal joint air duct 55 is turned into the granulator 1. The centrifugal fan 51 delivers the heated air inside the electric heating box 41 to the granulator 1 through the main air duct 52 and the branch air duct 53, thereby achieving sufficient heating of the granules with hot air at a constant temperature. The hot air with kinetic energy can also make the moisture in the granules evaporate quickly, so that the granules quickly reach the required softening state. The universal joint air duct 55 can change shape, so that the position and angle can be adjusted according to the needs. In this embodiment, multiple sets of branch air ducts 53 are also provided, and multiple sets of branch air ducts 53 can heat the granules in multiple sets of granulators 1.

[0040] Reference Figure 3 When the output amount of powder needs to be adjusted during the granulation process, in this embodiment, a drive motor 22 is fixedly installed at the end of the powder tank 2 near the discharge pipe 21. A spiral blade 221 is welded to the output end of the drive motor 22. When the drive motor 22 is started, the drive motor 22 drives the spiral blade 221 to rotate. The rotation of the spiral blade 221 conveys the powder in the powder tank 2 to the granulator 1 along the discharge pipe 21. During the spiral conveying process, the powder will be turned over to reduce agglomeration, thereby achieving uniform addition of powder into the granulator 1 and improving the subsequent shaping and polishing effect. Moreover, the drive motor 22 can be adjusted according to the granulation requirements to control the powder output rate.

[0041] Reference Figure 5To adjust the water flow rate in the outlet pipe 31, a solenoid valve 311 and a pressure gauge 312 are fixedly installed on the outlet pipe 31 in this embodiment. When granulation is required, the solenoid valve 311 is opened, allowing water from the storage tank 3 to enter the granulator 1 through the outlet pipe 31. The pressure gauge 312 on the outlet pipe 31 can provide real-time feedback on the water pressure in the outlet pipe 31, facilitating the control of the water flow rate in the outlet pipe 31. In this embodiment, multiple outlet pipes 31 are welded together with return pipes. The solenoid valve 311 is installed between the two connection points of the return pipe and the outlet pipe 31. A valve is fixedly installed on the return pipe, and valves are fixedly installed at both ends of the solenoid valve 311. When the solenoid valve 311 malfunctions, the valves at both ends of the solenoid valve 311 can be manually closed, and the water flow can continue to enter the granulator 1 through the return pipe. This does not affect the granulator 1's granulation process, and the solenoid valve 311 can be repaired or replaced without stopping the machine.

[0042] Reference Figure 5 During the granulation process of the granulator 1, the water outlet height and angle of the water outlet pipe 31 may be adjusted according to actual usage requirements. Therefore, in this embodiment, a metal shaped hose 313 is fixedly installed at the end of the water outlet pipe 31 near the granulator 1.

[0043] Reference Figure 4 When heating the air inside the electric heating box 41, in order to improve heating efficiency, the heating tube 42 in this embodiment is arranged in multiple U-shapes and multiple sets are installed. The multiple sets of heating tubes 42 are installed at intervals in height. The multiple sets of multi-U-shaped heating tubes 42 can increase the contact area with the air and improve the heating efficiency of the air.

[0044] Reference Figure 2 , Figure 4 and Figure 5 In order to improve the operating efficiency of the device and reduce labor costs, a control cabinet 6 is fixedly installed on one side of the granulator 1 in this embodiment. The control cabinet 6 can coordinate and centrally control the operation of the granulator 1, the drive motor 22, the solenoid valve 311, the electric heating box 41, the centrifugal fan 51 and the thermocouple 43.

[0045] The implementation principle of the particle polishing and forming device in this application embodiment is as follows:

[0046] The heating mechanism 4 does not directly contact the working space inside the granulator 1. When the heating mechanism 4 is working, the primary filter cotton 44 and the secondary filter cotton 45 can prevent dust from entering the electric heating box 41, thus avoiding damage to the electric heating box 41 and causing safety hazards.

[0047] The electric heating box 41 is started, and the heating tube 42 heats the air inside the electric heating box 41. The thermocouple 43 detects the temperature inside the electric heating box 41 and at the air outlet. When the set temperature is reached, the centrifugal fan 51 is started and the hot air valve 54 is opened. At the same time, the universal joint air duct 55 is turned into the granulator 1. The centrifugal fan 51 transports the heated air inside the electric heating box 41 to the granulator 1 through the main air duct 52 and the branch air duct 53. The flowing hot air fully heats the granules, causing the moisture inside the granules to evaporate quickly and the granules to reach the required softening state quickly, thereby improving the shaping and polishing effect of the granules.
