Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical equipment, in particular to a fluidized bed granulating dryer with a double-exhaust piston-type regulating air door. Background Art

[0002] The pharmaceutical fluidized bed dryer is designed for efficient, safe, and environmentally friendly pharmaceutical drying and cooling. It utilizes advanced feeding, air filtration, heating, refrigeration, and dehumidification systems, as well as control systems, to ensure high quality and efficiency during the drying and granulation processes. The fluidized bed granulation dryer utilizes air heated by a heat exchanger, which then flows through a funnel-shaped hopper with a gas distribution screen at the bottom, creating numerous high-speed air streams that flush the material and cause it to boil. This state allows the heated air to come into extensive contact with the material, rapidly evaporating and separating the moisture from the material. The moist air then exits through the shaker bag, while the retained material becomes the dry product. The air then exits the equipment through a damper.

[0003] However, when the material is boiling, the material will adhere to the shaking bag under the action of airflow, causing the shaking bag to be blocked. The shaking bag needs to be shaken frequently, and the damper must be closed when shaking the bag. However, if the damper is completely closed, the material will not boil, which may easily cause the pot to collapse. Utility Model Content

[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0020] like Figures 1 to 4 As shown, Figure 1 This is the overall structural diagram of the fluidized bed granulating dryer with double exhaust piston type damper. Figure 2 Schematic diagram of the setting position of the damper assembly 7, Figure 3 Schematic diagram of the setting position of the sealing gasket 3. Figure 4The figure is a schematic diagram of the structure of cylinder 1. The present invention provides a fluidized bed granulation dryer with a dual-exhaust piston-type damper, comprising a sealing seat 4, a sealing gasket 3, a cylinder 1, a damper assembly 7, and an air outlet 2. The above-described solution enables the use of a flexible sealing gasket 3 in conjunction with a rigid damper, utilizing the elastic deformation properties of the flexible sealing gasket 3 to enhance the damper's sealing performance. It is understood that the above-described solution can enhance the damper's sealing performance.

[0021] In this embodiment, the sealing seat 4 is used for sealing during operation.

[0022] Among them, the damper assembly 7 is arranged parallel to the upper and lower parts of the sealing seat 4, and the rigid damper of the damper assembly 7 is tightly attached to the sealing gasket 3 on the sealing seat 4 when sealing. The damper shaft 5 between the cylinder 1 and the damper assembly 7 is connected, and a shock-absorbing seat 6 is installed on the damper shaft 5; the damper assembly 7 will be arranged parallel to the sealing seat 4 up and down when set and installed, and form a double damper structure. The rigid damper of the damper assembly 7 will be able to fit tightly with the sealing gasket 3 on the sealing seat 4 when sealing, thereby minimizing the air gap and achieving good sealing. The cylinder 1 is fixed to the body by bolts, and the damper shaft 5 set between the damper assemblies 7 is connected to the output end of the cylinder 1 by bolts to achieve fixed assembly, and the shock-absorbing seat 6 is installed on the damper shaft 5 so that good shock absorption assistance can be provided during operation.

[0023] After the damper of the damper assembly 7 is opened, the air flow is discharged through the air outlet 2 .

[0024] Secondly, the shock-absorbing seat 6 reduces the vibration of the damper assembly 7 when the cylinder 1 is extended and retracted. The function of the shock-absorbing seat 6 is to reduce the vibration of the damper assembly 7 when the cylinder 1 is extended and retracted, thereby improving stability.

[0025] Then, the sealing gasket 3 adopts a rubber gasket. A rubber sealing gasket is a sealing component used in mechanical equipment, usually made of rubber, and has the advantages of acid resistance, alkali resistance, oil resistance, wear resistance, and high pressure resistance. It can maintain its sealing performance unchanged in a high temperature environment. The rubber sealing gasket has some excellent characteristics: 1. Good sealing performance. The rubber sealing gasket can effectively prevent the leakage of air, water and other media, and provide excellent sealing performance. 2. Higher wear resistance: Special rubber materials such as silicone rubber have good wear resistance and can effectively extend the service life. 3. Good elasticity and toughness: The rubber sealing gasket has good elasticity and toughness and can adapt to deformation and vibration in various environments. Therefore, after the sealing gasket 3 adopts a rubber gasket, it will be able to achieve stable sealing and have a certain elastic deformation ability during operation.

[0026] Furthermore, the cylinder 1 is a single-rod cylinder. A single-rod cylinder typically consists of a cylinder body, a piston, a piston rod, a seal, an end cap, an air inlet, and an exhaust port. The cylinder body is the main component of the single-rod cylinder, while the piston and piston rod are the moving elements within the cylinder. The seal ensures the cylinder's tightness. Single-rod cylinders typically use compressed air as their power source. Their operating principle is as follows: 1. Compressed air enters the cylinder. When the cylinder's air inlet opens, external compressed air enters the cylinder, pushing the piston toward the end cap. 2. The piston moves. When the piston moves toward the end cap, the piston rod extends from the piston rod hole in the end cap, completing the cylinder's operation. 3. Exhaust. When the compressed air within the cylinder completes the cylinder's operation, the cylinder's exhaust port opens, expelling any remaining compressed air. Furthermore, single-rod cylinders offer excellent performance: 1. Simple Structure: Single-rod double-acting cylinders have a very simple structure, consisting of a cylinder and a piston. Therefore, their manufacturing and maintenance costs are relatively low. 2. High Reliability: Single-rod, double-acting cylinders use gas pressure as their power source, ensuring smooth and reliable operation, low malfunction rates, and a long service life. 3. Small Size and Light Weight: Single-rod, double-acting cylinders are compact, take up little space, are lightweight, and are easy to install. 4. Excellent Tensile Strength: The rod of a single-rod, double-acting cylinder only bears pressure, not tension, resulting in excellent tensile strength. Therefore, using a single-rod cylinder as cylinder 1 ensures excellent stability during operation, facilitating stable operation of the equipment.

[0027] Finally, the number of cylinders 1 is two. The number of cylinders 1 is set to two, which is convenient for forming a double exhaust structure and a double bag shaking structure when the equipment is working. When shaking the bag, the corresponding damper is closed by the action of one of the cylinders 1, and the other damper is opened and works normally by the action of the other cylinder 1, so that the material can continue to boil.

[0028] When the utility model is used to realize a structure in which a flexible sealing gasket 3 and a rigid damper are matched, and the elastic deformation characteristics of the flexible sealing gasket 3 are utilized to enhance the sealing performance of the damper, in the present application, the damper assembly 7 is arranged parallel to the upper and lower parts of the sealing seat 4 to form a double damper structure. The rigid damper of the damper assembly 7 is tightly attached to the sealing gasket 3 on the sealing seat 4 during sealing. The sealing gasket 3 adopts a rubber gasket, which can achieve stable sealing during operation and can undergo certain elastic deformation. The damper shaft 5 between the cylinder 1 and the damper assembly 7 is connected, and a shock-absorbing seat 6 is installed on the damper shaft 5. The shock-absorbing seat 6 can reduce the vibration of the damper assembly 7 when the cylinder 1 moves and retracts. Improve stability. Finally, after the damper of the damper assembly 7 is opened, the air flow is discharged through the air outlet 2. Therefore, through the above structure, the structure of the present application can be designed as a double exhaust structure, a double shaking bag structure. When shaking the bag, the corresponding damper is closed by the action of one of the cylinders 1, and the damper on the other side is opened and works normally by the action of the other cylinder 1, and the material can continue to boil. At the same time, a flexible sealing gasket 3 and a rigid damper are used in combination, and the elastic deformation characteristics of the flexible sealing gasket 3 are used to enhance the sealing of the damper. The structure is simple and reasonable, and the sealing effect is good. Therefore, a structure in which a flexible sealing gasket 3 and a rigid damper are used in combination can be realized, and the elastic deformation characteristics of the flexible sealing gasket 3 are used to enhance the sealing of the damper.

A person skilled in the art will understand that all or part of the processes of the above embodiments and equivalent changes made in accordance with the claims of the present application are still within the scope of the present application.
