Abstract
Description
Technical Field
[0001] This utility model relates to the field of dryer technology, specifically a double cone dryer with filtration function. Background Technology
[0002] As is well known, the double cone dryer is a new type of dryer that integrates mixing and drying. The double cone dryer consists of a double-cone rotating tank. Inside the tank, under vacuum, a heating medium is introduced into the jacket for heating. Heat is transferred to the wet material through the inner wall of the tank. The water vapor evaporated from the wet material after absorbing heat is then removed by a vacuum pump through a vacuum exhaust pipe. Because the tank is under vacuum, and the rotation of the tank causes the material to continuously move up and down and inside and out, the drying speed is accelerated, drying efficiency is improved, and uniform drying is achieved.
[0003] However, most dual-cone dryers on the market currently discharge gas directly from their exhaust pipes. Due to the lack of an effective gas filtration device, particulate dust generated inside the machine during the drying process is easily discharged along with the exhaust gas, thus polluting the surrounding environment. This direct discharge method not only fails to meet environmental protection requirements, but may also affect product quality and increase the cost of subsequent environmental remediation and cleaning in some production scenarios with strict requirements for environmental cleanliness. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a double cone dryer with filtration function.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a double cone dryer with filtration function, comprising a base plate, a body, an exhaust pipe, and a filtration mechanism. The body is disposed on the top of the base plate, and the exhaust pipe is disposed on the body. The filtration mechanism comprises a filter assembly, a connecting plate, a first bolt, a sealing cover, a long block, a rubber block, a frame, a limiting plate, and a second bolt. The filter assembly is disposed inside the exhaust pipe. One end of the connecting plate is connected to the filter assembly, and the other end of the connecting plate abuts against the top of the exhaust pipe. The connecting plate is connected to the exhaust pipe via the first bolt. The sealing cover is threadedly connected to the outer wall of the exhaust pipe. The frame is disposed on the top of the sealing cover. One end of the long block is connected to the rubber block, and the other end of the long block passes through the sealing cover and the frame and is connected to the limiting plate.

[0022] 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.
[0023] Please see Figure 1-4 A double cone dryer with filtration function includes a base plate 1, a body 2, an exhaust pipe 3, and a filtration mechanism 4. The body 2 is disposed on the top of the base plate 1, and the exhaust pipe 3 is disposed on the body 2. The filtration mechanism 4 includes a filter assembly 5, a connecting plate 6, a first bolt 7, a sealing cover 8, a long block 9, a rubber block 10, a frame 11, a limiting plate 12, and a second bolt 13. The filter assembly 5 is disposed inside the exhaust pipe 3. One end of the connecting plate 6 is connected to the filter assembly 5, and the other end of the connecting plate 6 abuts against the top of the exhaust pipe 3. The connecting plate 6 and the exhaust pipe 3 are connected by the first bolt 7. The sealing cover 8 is threadedly connected to the outer wall of the exhaust pipe 3. The frame 11 is disposed on the top of the sealing cover 8. One end of the long block 9 is connected to the rubber block 10, and the other end of the long block 9 passes through the sealing cover 8 and the frame 11 and is connected to the limiting plate 12. The long block 9 and the frame 11 are connected by the second bolt 13.
[0024] Working principle: Before starting the equipment, it needs to be placed in the designated position and the base plate 1 provides stable support for the equipment. Then, connect the external mains power to power the equipment. The machine body 2 adopts the conventional double cone dryer structure on the market, including double cone cylinder, heating mechanism, transmission mechanism, vacuum system, feeding component and discharging component, etc. The specific structure will not be described in detail here.
[0025] During the material processing stage, refer to Figure 1First, separate the sealing cover 8 from the exhaust pipe 3. At this time, the equipment is running. The exhaust pipe 3 is responsible for expelling the gas inside the machine body 2. During this process, the filter component 5 plays a key role. It can effectively intercept particulate dust inside the machine body 2 and prevent it from being discharged with the gas, thereby avoiding pollution to the surrounding environment. However, this equipment is only suitable for processing ordinary materials that are non-toxic, harmless, odorless, and do not produce flammable or explosive gases or dust. Under the condition of meeting local environmental protection requirements, the treated gas can be directly discharged into the air.
[0026] After the material processing is completed, the material is first discharged from the machine body 2 through the discharge component. Then, the operator holds the sealing cover 8 and makes the rubber block 10 contact the filter component 5. The operator gently taps the rubber block 10 to make the dust particles attached to the filter component 5 fall into the machine body 2 to prevent dust from clogging the filter component 5. Then, the discharge component is used again to discharge these dust particles. If the filter component 5 needs to be deeply cleaned, the first bolt 7 can be unscrewed with an external screwdriver to separate the first bolt 7 from the connecting plate 6 and the exhaust pipe 3. This allows the filter component 5 to be disassembled and then cleaned with the help of external flushing equipment and other tools. The cleaning method is not specifically limited.
[0027] When the equipment is idle, refer to Figure 1 Tighten the second bolt 13 with a screwdriver to separate it from the frame 11 and the long block 9. Then, hold the limiting plate 12 and pull the long block 9 so that it contacts the top of the inner wall of the sealing cover 8. Since the long block 9 has two threaded grooves, the other threaded groove matches the position of the threaded hole on the frame 11. Then, use the second bolt 13 to connect and fix the two. After that, place the sealing cover 8 on the exhaust pipe 3 and tighten it. Since both the inner wall of the sealing cover 8 and the outer wall of the exhaust pipe 3 are threaded, the two can be tightly threaded together. In this way, when the equipment is not in use, the sealing cover 8 can seal the exhaust pipe 3 to prevent external dust particles from falling into the filter assembly 5 and avoid clogging. Before the equipment is used next time, the sealing cover 8 needs to be unscrewed.
[0028] At the edge where the filter assembly contacts the exhaust pipe 3, a ring of high-temperature resistant and wear-resistant sealing rubber gasket is provided to enhance the sealing effect. When tightening the first bolt 7, a torque wrench is used to operate according to the specified torque value to ensure that the tightening force of each bolt is uniform and reaches the appropriate standard. At the same time, the tightness of the first bolt 7 is checked regularly. After the equipment has been running for a period of time, any loose bolts are tightened again. In addition, thread locking agent is applied to the threaded part of the first bolt 7 to further prevent the bolt from loosening under vibration. After the filter assembly 5 is installed in place, multiple wedge-shaped rubber gaskets are evenly inserted in the circumferential direction between the connecting plate 6 and the top of the exhaust pipe 3. These gaskets can fill any small gaps that may exist between the connecting plate 6 and the exhaust pipe 3, enhance the tightness of the connection, and play a buffering role during vibration, reducing the shaking of the filter assembly 5, thereby reducing the risk of loosening, and also helping to maintain the sealing effect.
[0029] The filter assembly 5 described in the text includes a stainless steel frame 11 and a filter screen made of sintered metal fibers. The sintered metal fibers have high strength, high air permeability, and good filtration performance. Its internal structure is compact and has a certain degree of elasticity. When it is hit by a rubber block 10, it can buffer the impact force through its own elastic deformation, reducing damage to the structure. For example, nickel-based alloy sintered metal felt can not only efficiently filter fine dust, but also adapt to relatively frequent knocking and cleaning operations, and has a long service life.
[0030] All threaded surfaces in this structure undergo special treatment. The metal threads are chrome-plated, which has high hardness and a low coefficient of friction, forming a wear-resistant and corrosion-resistant protective film on the thread surface. This reduces direct friction during tightening and lowers the degree of wear. Alternatively, chemical nickel plating can be used to form a uniform nickel-phosphorus alloy coating on the thread surface, improving the thread's hardness and wear resistance, while also enhancing its corrosion resistance and further protecting the thread structure.
[0031] The filter assembly 5 of this equipment is securely connected to the exhaust pipe 3 via the connecting plate 6 and the first bolt 7. Even if the machine body 2 rotates the exhaust pipe 3, the connection effect will not be affected, ensuring the stability of the filter assembly 5. Furthermore, based on the applicability of the equipment to materials, the treated gas can be directly discharged, and the exhaust pipe 3 does not need to be connected to external equipment. This structure focuses on the processing of common materials, giving the equipment a significant advantage in cost control. There is no need to invest high costs in special processing functions required to deal with complex materials, which effectively reduces the manufacturing cost of the equipment. Although the range of applicable materials is limited, its application scenarios in the field of common material processing are extremely wide. The drying of common materials such as food additives, some pharmaceutical raw materials, and common chemical powders all have strict requirements for environmental cleanliness and material quality stability. With its precise design, this equipment can excellently meet these requirements and provide stable and reliable drying services for related industries.
[0032] In this embodiment, to further improve the connection effect, several connecting plates 6 and first bolts 7 are specially set. These connecting plates 6 are symmetrically distributed, which can evenly distribute the force and avoid local stress concentration. The corresponding first bolts 7 are also symmetrically arranged. In this way, the connection between the filter assembly 5 and the exhaust pipe 3 can be more stable and reliable, effectively ensuring the structural stability of the equipment during operation.
[0033] In this embodiment, from the perspective of ensuring the stability and reliability of the connection, the number of second bolts 13 is set to two, and the two second bolts 13 are symmetrically distributed. This symmetrical arrangement can make the connection between the long block 9 and the frame 11 more uniformly stressed, effectively avoiding the loosening of the connection due to uneven stress, and thus effectively improving the connection effect.
[0034] In this embodiment, to ensure the overall performance of the equipment's exhaust and sealing, the sealing cover 8 and the exhaust pipe 3 were carefully designed. The sealing cover 8 and the exhaust pipe 3 are highly compatible in terms of size and thread specifications. This precise design allows the sealing cover 8 to be tightly installed on the exhaust pipe 3, which not only ensures the sealing performance during gas exhaust but also prevents external impurities from entering, thus achieving the ideal docking effect.
[0035] In the design considerations of this embodiment, in order to effectively improve the strength of the base plate 1 and meet the needs of the equipment to bear the machine body and various materials during long-term use, after comprehensive evaluation and screening, alloy steel was finally selected to make the base plate 1. Alloy steel has high strength, good wear resistance and fatigue resistance, which can provide stable support for the equipment and ensure stable operation of the equipment.
[0036] In this embodiment, in order to optimize the connection effect between the frame 11 and the sealing cover 8 and enhance the stability of the overall structure, a welding connection method is adopted. Welding can make the frame 11 and the sealing cover 8 form a solid whole, reducing potential problems caused by loose connection. Compared with other connection methods, welding can significantly improve the bonding strength between the two and ensure stable and reliable connection during equipment operation.
[0037] The dimensions and shapes of all components in this structure are not specifically limited here and need to be produced according to the actual situation. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in this field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and wiring layout will not be explained in detail here.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
