Description

Technical Field

[0001] The utility model relates to the field of pharmaceutical equipment, in particular to a wet-processing machine integrating granulation and drying. Background Art

[0002] The wet mixing granulator can complete the mixing, humidification and granulation processes at one time. It is suitable for the pharmaceutical, food, chemical and other industries. It has the characteristics of high efficiency, high quality, low consumption, no pollution and safety.

[0003] For example, the utility model patent with authorization announcement number CN 208082423 U provides a multi-specification wet mixing granulator, which includes a base, a mixing drive motor, a cutting drive motor and a material cylinder. The mixing drive motor and the cutting drive motor are both installed on the base, and the bottom surface of the material cylinder is connected to the upper surface of the base. The bottom surface of the material cylinder is provided with an installation port for vertically inserting the output shaft of the mixing drive motor and the stirring paddle. The output shaft of the mixing drive motor is located inside the material cylinder. One end is fixedly connected to the stirring paddle for stirring the material; a cutting blade is rotatably connected to the inner wall of the material cylinder, and the bottom surface of the material cylinder is detachably fixedly connected to the base; the granulator also includes a cutting shaft rotatably connected to the material cylinder, and a transmission shaft is transmission-connected between the cutting shaft and the output shaft of the cutting drive motor. The end of the transmission shaft close to the cutting drive motor is fixedly connected to a first connecting disk, and a second connecting disk is fixedly connected to the output shaft of the cutting drive motor. The first connecting disk and the second connecting disk are fastened by bolts.

[0004] At present, conventional wet mixing granulators usually use vacuum pipes for automatic transmission or manual transportation after granulation is completed, so that the materials are transported to the back-end fluidized bed, oven and other drying equipment for drying. During the entire transmission process, some material will be lost, and for some high-value materials, there will be considerable economic losses. Therefore, the applicant hopes to design a wet mixing machine that can realize the integration of granulation and drying, reduce the loss of materials in the later transportation process, and improve the practicality of the wet mixing machine. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings and deficiencies of the existing technology and to provide a wet granulation machine with integrated granulation and drying. The technical solutions adopted by this utility model are as follows:

[0006] A wet process machine integrating granulation and drying comprises a base and a material cylinder, wherein a stirring assembly and a granulating assembly are provided in the material cylinder, and a driving motor for driving the stirring assembly and the granulating assembly is provided outside the material cylinder. An interlayer separated from the material and performing heat transfer with the material is provided on the material cylinder, wherein the interlayer has a liquid inlet for introducing liquid and a liquid outlet for discharging liquid, and the liquid inlet is located below the liquid outlet. A water interlayer is added outside the wet process material cylinder, and hot water or heat-conducting oil can be introduced into the interlayer according to the characteristics of the material to accelerate the evaporation of water in the material by heat exchange.

[0007] Preferably, the interlayer also has a drain port, which is located at the bottom of the interlayer, and an anti-scalding protective layer is provided on the outside of the interlayer. The anti-scalding protective layer is added on the outside of the interlayer to prevent the operator from getting burned when high-temperature liquid is injected into the interlayer.

[0008] Preferably, a filter is installed on the top of the material cylinder, and the filter is connected to a vacuum device to extract and filter air from the material cylinder. The filter and the vacuum device are passed on the wet cylinder cover to vacuum the material cylinder, reduce the boiling point of water, and improve the overall drying efficiency.

[0009] Preferably, the lower end of the material cylinder is connected to a compressed air supply device, and an air-sealing structure is provided at the stirring and granulating assembly at the bottom of the material cylinder; preferably, a compressed air supply device with a temperature control function is provided to blow hot compressed air into the material cylinder from the bottom of the material cylinder, which can improve the overall drying efficiency.

[0010] Preferably, a swing mechanism is provided on both sides of the material cylinder, and the swing mechanism includes extension brackets extending from both sides of the material cylinder, and a driving mechanism connected to the extension brackets through chain links or synchronous belts, and the driving mechanism drives the material cylinder to swing to both sides within a range of 0-90 degrees through the extension brackets; on the one hand, the swing mechanism can cooperate with the rotation of the stirring paddle to continuously change the contact position between the material and the pot wall for heat exchange and accelerate the drying of the material; on the other hand, the center of the stirring paddle of a conventional wet mill has a relatively low linear speed and relatively weak material scouring, and a large amount of material will adhere to the center of the stirring paddle, while the swing of the material cylinder causes the material to continuously scour the inside of the pot body, greatly reducing the adhesion of the material in the material cylinder and effectively improving the mixing uniformity of the material in the pot.

[0011] At the same time, the material cylinder has an automatic swing function. When discharging materials, the tilt angle of the material cylinder can be controlled. Without manual intervention, a higher material yield can be obtained.

[0012] Preferably, the stirring and granulating assembly and the swing mechanism both adopt an electric drive mechanism. Compared with the hydraulic method, the hydraulic transmission efficiency is low, the energy consumption is high, there is a risk of leakage and pollution, and the manufacturing precision and cost of the hydraulic components are high; due to the specific compressibility and leakage problems of the liquid, its transmission precision is relatively reduced, the overall operating stability is not as good as the electric drive, and the difficulty of manual troubleshooting is relatively high; under the condition of high output torque, the hydraulic oil requires a separate cooling system, and the system configuration is complex, so electric drive is preferred.

[0013] The beneficial effects of the present invention are as follows: This technical solution adds a heat-conducting interlayer outside the material cylinder of the wet process machine, so that after the material is granulated and stirred in the material cylinder, the operator can pass hot water or heat-conducting oil into the interlayer according to the characteristics of the material, and accelerate the evaporation of moisture in the material through heat exchange, so that the material can be granulated, mixed and dried in the same container, reducing the loss of material during the transportation process and saving costs.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0020] The directional and positional terms used in this invention, such as "upper," "lower," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are used solely to refer to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are intended to illustrate and facilitate understanding of this invention and are not intended to limit the scope of protection of this invention.

[0021] like Figure 1-3As shown, a wet process machine integrating granulation and drying comprises a base and a material cylinder 1, wherein a stirring assembly and a granulating assembly are provided in the material cylinder 1, and a driving motor for driving the stirring assembly and the granulating assembly is provided outside the material cylinder 1, and an interlayer 11 is provided on the material cylinder 1, which is separated from the material and transfers heat with the material, and the interlayer 11 has a liquid inlet 101 for introducing liquid and a liquid outlet 102 for discharging liquid, and the liquid inlet 101 is located below the liquid outlet 102; a water interlayer is added outside the wet process material cylinder, and hot water or heat-conducting oil can be introduced into the interlayer according to the characteristics of the material to accelerate the evaporation of water in the material by heat exchange; the interlayer 11 also has a drain port 103, and the drain port 103 is located at the bottom end of the interlayer 11, and the liquid inlet 101, the liquid outlet 102 and the drain port 103 are all connected to corresponding liquid pipelines.

[0022] An anti-scalding protective layer is provided on the outside of the interlayer 11 to prevent an operator from getting close to the interlayer and getting burned when high-temperature liquid is injected into the interlayer.

[0023] The top of the cylinder 1 is provided with a filter 2, and the filter 2 is connected to a vacuum device. Figure 2 The vacuum port 21 shown is used to extract and filter air from the material cylinder 1. The filter and the exhaust device on the wet cylinder cover can be used to vacuum the material cylinder, thereby reducing the boiling point of water and improving the overall drying efficiency.

[0024] The lower end of the material cylinder 1 is connected to a compressed air introduction device, and an air-sealing structure is provided at the stirring and granulating assembly at the bottom of the material cylinder. In this embodiment, a compressed air introduction device with a temperature control function is selected to blow hot compressed air into the material cylinder from the bottom of the material cylinder to improve the overall drying efficiency; the compressed air introduction device is provided with a one-way valve and a filter to avoid backflow of material and ensure uniform air intake.

[0025] A swing mechanism is provided on both sides of the cylinder 1, and the swing mechanism includes an extension bracket 104 extending from both sides of the cylinder 1, and a driving mechanism connected to the extension bracket 104 through a chain link or a synchronous belt. The driving mechanism drives the cylinder 1 to swing within a range of 0-90 degrees on both sides through the extension bracket 104. Figure 3 As shown, the extension bracket 104 also has the function of converging the pipeline; the specific setting is: a reducer is set on the side of the material cylinder, and the pot body is swung at ±90° through a chain link or a synchronous belt; on the one hand, the rotation of the stirring paddle can continuously replace the contact position between the material and the pot wall to exchange heat and accelerate the drying of the material. On the other hand, the center of the stirring paddle of a conventional wet mill has a relatively low linear speed and relatively weak material scouring, and a large amount of material will adhere to the center of the stirring paddle. The swing of the material cylinder causes the material to continuously scour the inside of the pot body, greatly reducing the adhesion of the material in the material cylinder and effectively improving the mixing uniformity of the material in the pot.

[0026] At the same time, the material cylinder has an automatic swing function. When discharging materials, the tilt angle of the material cylinder can be controlled to obtain a higher material recovery rate.

[0027] The stirring and granulating assembly and the swing mechanism both adopt electric drive mechanisms. Compared with the hydraulic method, the hydraulic transmission efficiency is low, the energy consumption is high, there is a risk of leakage and pollution, and the manufacturing precision and cost of the hydraulic components are high. Due to the specific compressibility and leakage problems of the liquid, its transmission precision is relatively reduced, the overall operating stability is not as good as that of the electric drive, and the difficulty of manual troubleshooting is relatively high. Under high output torque conditions, the hydraulic oil requires a separate cooling system, and the system configuration is complex. Therefore, electric drive is preferred.

[0028] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
