Description

Technical Field

[0001] This utility model relates to the field of fertilizer processing technology, specifically to a fertilizer vibrating fluidized bed drying device. Background Technology

[0002] In agricultural production, fertilizers are essential materials for ensuring crop growth and increasing yield. To guarantee the quality and storage stability of fertilizers, drying is a key step in the fertilizer production process. However, traditional fertilizer drying technologies have many problems.

[0003] In the early days, some fertilizer manufacturers used static drying methods, which involved piling fertilizer in a specific area and drying it through natural ventilation or simple heating equipment. This method was extremely inefficient and time-consuming, making it unsuitable for large-scale production. Moreover, because the fertilizer was piled together, the internal moisture was difficult to dissipate, leading to uneven drying and affecting the quality and performance of the fertilizer.

[0004] Later mechanical drying equipment, while improving drying efficiency to some extent, mostly had complex structures and high energy consumption. For example, some drum dryers require rotating drums to move the fertilizer and achieve contact drying with hot air. However, this type of equipment consumes a lot of electricity to drive the drum rotation, and the uneven airflow distribution inside the drum also leads to inconsistent fertilizer drying results. Utility Model Content

[0005] The purpose of this invention is to provide a fertilizer vibrating fluidized bed drying device that can improve the drying effect and efficiency of fertilizers, and reduce dust emissions and energy consumption.

[0006] A fertilizer vibrating fluidized bed drying device includes a mounting base, a drying chamber, a top cover, a filter, and a hot air device. The hot air device is connected to the drying chamber. Multiple elastic elements are connected between the drying chamber and the mounting base. Several vibration drive elements are installed on the drying chamber. The filter is installed on the top of the drying chamber. The top cover covers the outer periphery of the filter and is connected to the drying chamber. The top cover has a discharge port and a feed port. The discharge port is located above the filter, and the feed port is located on the side of the top cover.

[0007] In the above scheme, fertilizer material flows into the drying chamber from the feed inlet. Multiple elastic components connecting the drying chamber and the mounting base, together with several vibration drive components installed on the drying chamber, cause the drying chamber to vibrate at a specific frequency and amplitude. Under the action of vibration, the fertilizer particles in the drying chamber exhibit a fluid-like state, which greatly increases the contact area and contact opportunities between the particles and the hot air. The hot air device delivers heated air to the drying chamber, and the hot air comes into full contact with the fluidized fertilizer. According to the principle of heat transfer, heat is transferred from the hot air to the surface of the fertilizer particles, causing the moisture on the particle surface to evaporate rapidly. At the same time, because the fertilizer particles are in a fluidized state, the internal moisture can diffuse to the surface more quickly and be continuously carried away by the hot air, thereby achieving efficient drying. The air is filtered through a filter and discharged through the exhaust port.

[0008] Furthermore, the drying chamber includes a cylindrical body, a feeding funnel, a first screen, and a second screen. The feeding funnel is connected to the cylindrical body, and the first screen and the second screen are respectively installed at both ends of the cylindrical body. The first screen is adjacent to the filter, and the second screen is adjacent to the feeding funnel.

[0009] In the above scheme, after the fertilizer material flows into the drying chamber from the feed inlet, it passes through the first screen and enters the position between the first and second screens for drying. Under the combined action of vibration and hot air, the fertilizer particles can be effectively screened in the first and second screens. The first screen is located near the filter, which can intercept the dried fertilizer particles and prevent them from rising with the air and entering the filter. Oversized particles can be screened out to avoid mixing into the finished product and affecting product quality. The feeding funnel is connected to the cylinder and is close to the second screen. After drying and screening, the qualified fertilizer particles can smoothly pass through the second screen and fall into the feeding funnel after the hot air device is turned off, which is convenient for centralized collection and subsequent packaging processes.

[0010] Furthermore, the mounting base includes a mounting frame and a connecting base, the connecting base having a circular communication opening, and the smaller diameter end of the feeding funnel passing through the communication opening downwards.

[0011] In the above scheme, the mounting frame provides a solid support foundation for the entire drying equipment. The smaller diameter end of the feeding funnel is inserted downwards through the connecting port on the connecting seat, which fixes the feeding funnel, thereby making the drying chamber stably installed on the mounting seat.

[0012] Furthermore, the cylinder is provided with an annular protrusion structure, one end of the elastic element is connected to the protrusion structure, and the other end is connected to the connecting seat.

[0013] In the above scheme, the annular protrusion structure provides a stable and suitable connection position for the elastic element. When the vibration drive causes the drying chamber to vibrate, the elastic element can transmit the vibration evenly and efficiently to the cylinder through the protrusion structure. Compared with direct connection to other parts of the cylinder, the protrusion structure enhances the force-bearing capacity of the connection point, making the vibration energy more concentrated and orderly propagated in the drying chamber, thereby better driving the fertilizer granules to form a fluidized state, improving the contact effect between the granules and the hot air, and enhancing the drying efficiency.

[0014] Furthermore, the smaller diameter end of the feeding funnel is an air inlet, which is equipped with a valve and is detachably connected to an air inlet pipe. The other end of the air inlet pipe is connected to the hot air device.

[0015] In the above scheme, one end of the air inlet duct is connected to the air inlet, and the other end is connected to the hot air device. This allows the hot air to diffuse upwards more evenly after entering the drying chamber. This helps the hot air to fully contact the falling fertilizer particles, making the drying process more uniform and avoiding local over-drying or under-drying. This improves the drying quality and consistency of the fertilizer product. After drying is completed, the valve is closed and then the hot air device is turned off. After that, the air inlet duct is disassembled, the fertilizer collection container is placed facing the air inlet, and then the valve is opened to complete the collection of fertilizer.

[0016] Furthermore, the hot air device includes a centrifugal fan and a heating chamber. The outlet of the centrifugal fan is connected to a connecting channel, which is connected to the heating chamber. An electric heater is installed in the heating chamber.

[0017] In the above scheme, the centrifugal fan can generate strong wind and quickly deliver a large amount of air to the connecting channel through its air outlet. When the air enters the heating chamber through the connecting channel, the electric heater can quickly heat the air to the required temperature. This allows the drying equipment to reach the appropriate drying temperature in a short time. The hot air device ensures a continuous and stable supply of hot air in the drying chamber, so that the fertilizer granules can be fully fluidized and come into contact with the hot air, thereby improving the drying efficiency.

[0018] Furthermore, the vibration drive component is a vibration motor.

[0019] In the above scheme, the vibrating motor can generate vibrations of a specific frequency and amplitude. These vibrations can be transmitted to the drying chamber, causing the fertilizer particles to form a good fluidized state in the drying chamber. The gaps between the particles increase, and the contact area with the hot air increases, thereby accelerating the heat transfer and moisture evaporation, and greatly improving the drying efficiency.

[0020] Furthermore, a sealing cap is provided on the feed inlet.

[0021] In the above scheme, a certain pressure environment may be formed inside the drying equipment during operation. The sealing cover can prevent air from entering or leaving at will, which helps to maintain the stability of the internal pressure of the equipment. A stable pressure environment is very important for the normal operation of the equipment and the consistency of the drying effect. It can ensure that the hot air flows in the equipment according to the predetermined path and flow rate, thereby improving drying efficiency and quality.

[0022] This utility model discloses a fertilizer vibrating fluidized bed drying device, which has the beneficial effects of improving fertilizer drying effect and efficiency, reducing dust emissions, and lowering energy consumption. Fertilizer material flows into the drying chamber through the inlet. Multiple elastic components connecting the drying chamber and the mounting base, in conjunction with several vibration drive components installed on the drying chamber, cause the drying chamber to vibrate at a specific frequency and amplitude. Under the action of vibration, the fertilizer particles in the drying chamber exhibit a fluidized state similar to a fluid, greatly increasing the contact area and contact opportunities between the particles and hot air. A hot air device delivers heated air to the drying chamber, where the hot air fully contacts the fluidized fertilizer. According to the principle of heat transfer, heat is transferred from the hot air to the surface of the fertilizer particles, causing the moisture on the particle surface to evaporate rapidly. Simultaneously, because the fertilizer particles are in a fluidized state, the internal moisture can diffuse to the surface more quickly and be continuously carried away by the hot air, thus achieving efficient drying. The air is filtered through a filter and discharged through the outlet. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0029] like Figures 1 to 3 As shown in a preferred embodiment, the fertilizer vibrating fluidized bed drying equipment of this utility model includes a mounting base 1, a drying chamber 3, a top cover 2, a filter 7, and a hot air device 4. The hot air device 4 is connected to the drying chamber 3. A plurality of elastic elements 5 are connected between the drying chamber 3 and the mounting base 1. A plurality of vibration driving elements 6 are installed on the drying chamber 3. The filter 7 is installed on the top of the drying chamber 3. The top cover 2 covers the outer periphery of the filter 7 and is connected to the drying chamber 3. The top cover 2 is provided with a discharge port 21 and a feed port 22. The discharge port 21 is located above the filter 7, and the feed port 22 is located on the side of the top cover 2. Fertilizer material flows into the drying chamber 3 through the feed inlet 22. Multiple elastic elements 5 connecting the drying chamber 3 and the mounting base 1, together with several vibration drive elements 6 installed on the drying chamber 3, cause the drying chamber 3 to vibrate at a specific frequency and amplitude. Under the action of vibration, the fertilizer particles in the drying chamber 3 exhibit a fluidized state similar to a fluid, which greatly increases the contact area and contact opportunities between the particles and the hot air. The hot air device 4 delivers heated air to the drying chamber 3. The hot air fully contacts the fluidized fertilizer. According to the principle of heat transfer, heat is transferred from the hot air to the surface of the fertilizer particles, causing the moisture on the particle surface to evaporate rapidly, reducing energy consumption. At the same time, because the fertilizer particles are in a fluidized state, the internal moisture can diffuse to the surface more quickly and be continuously carried away by the hot air, thereby achieving efficient drying. The air is filtered through the filter 7 and discharged through the discharge port 21.

[0030] like Figures 1 to 3 As shown, in some embodiments, the drying chamber 3 includes a cylinder 31, a feeding funnel 32, a first screen 33 and a second screen 34. The feeding funnel 32 is connected to the cylinder 31. The first screen 33 and the second screen 34 are respectively installed at both ends of the cylinder 31. The first screen 33 is adjacent to the filter 7, and the second screen 34 is adjacent to the feeding funnel 32. After the fertilizer material flows into the drying chamber 3 through the feed inlet 22, it passes through the first screen 33 and enters the position between the first screen 33 and the second screen 34 for drying. Under the combined action of vibration and hot air, the fertilizer particles can be effectively screened in the first screen 33 and the second screen 34. The first screen 33 is located near the filter 7, which can intercept the dried fertilizer particles and prevent them from rising with the air and entering the filter 7. Particles that are too small can be screened out to avoid mixing into the finished product and affecting the product quality. The discharge funnel 32 is connected to the cylinder 31 and is close to the second screen 34. After the qualified fertilizer particles are dried and screened, they can smoothly pass through the second screen 34 and fall into the discharge funnel 32 after the hot air device 4 is turned off, which is convenient for centralized collection and subsequent packaging processes.

[0031] like Figures 1 to 3As shown, in some embodiments, the mounting base 1 includes a mounting frame 11 and a connecting base 12. The connecting base 12 has a circular communication opening, and the smaller diameter end of the feeding funnel 32 is inserted into the communication opening. The mounting frame 11 provides a solid support foundation for the entire drying equipment. The smaller diameter end of the feeding funnel 32 being inserted into the communication opening on the connecting base 12 fixes the feeding funnel 32, thereby ensuring that the drying chamber 3 is stably installed on the mounting base 1.

[0032] like Figures 1 to 3 As shown, in some embodiments, the cylinder 31 is provided with an annular protrusion structure 311. One end of the elastic member 5 is connected to the protrusion structure 311, and the other end is connected to the connecting seat 12. The annular protrusion structure 311 provides a stable and suitable connection position for the elastic member 5. When the vibration drive 6 causes the drying chamber 3 to vibrate, the elastic member 5 can transmit the vibration evenly and efficiently to the cylinder 31 through the protrusion structure 311. Compared with direct connection to other parts of the cylinder 31, the protrusion structure 311 enhances the force-bearing capacity of the connection point, making the vibration energy more concentrated and orderly propagated in the drying chamber 3, thereby better driving the fertilizer granules to form a fluidized state, improving the contact effect between the granules and the hot air, and enhancing the drying efficiency.

[0033] like Figures 1 to 3 As shown, in some embodiments, the smaller diameter end of the feeding funnel 32 is the air inlet 321. The air inlet 321 is equipped with a valve and is detachably connected to an air inlet pipe. The other end of the air inlet pipe is connected to the hot air device 4. Connecting one end of the air inlet pipe to the air inlet 321 and the other end to the hot air device 4 allows the hot air to diffuse upwards more evenly after entering the drying chamber 3. This helps the hot air to fully contact the falling fertilizer particles, making the drying process more uniform and avoiding localized over-drying or under-drying, thereby improving the drying quality and consistency of the fertilizer product. After drying is complete, the valve is closed, and then the hot air device 4 is turned off. The air inlet pipe is then disassembled, the fertilizer collection container is positioned over the air inlet 321, and the valve is opened to complete the fertilizer collection.

[0034] like Figure 4 In some embodiments, the hot air device 4 includes a centrifugal fan 41 and a heating chamber 43. The outlet of the centrifugal fan 41 is connected to a connecting channel 42, which is connected to the heating chamber 43. An electric heater 44 is installed inside the heating chamber 43. The centrifugal fan 41 can generate strong airflow, rapidly delivering a large amount of air to the connecting channel 42 through its outlet. When the air enters the heating chamber 43 through the connecting channel 42, the electric heater 44 can quickly heat the air to the required temperature. This allows the drying equipment to reach a suitable drying temperature in a short time. The hot air device 4 ensures a continuous and stable supply of hot air in the drying chamber 3, allowing the fertilizer granules to be fully fluidized and in contact with the hot air, thereby improving drying efficiency.

[0035] like Figures 1 to 3 As shown, in some embodiments, the vibration drive 6 is a vibration motor. The vibration motor can generate vibrations of a specific frequency and amplitude, which can be transmitted to the drying chamber 3, causing the fertilizer particles to form a good fluidized state within the drying chamber 3. The gaps between the particles increase, and the contact area with the hot air increases, thereby accelerating the rate of heat transfer and moisture evaporation, and greatly improving the drying efficiency.

[0036] like Figures 1 to 3 As shown, in some embodiments, a sealing cover 8 is provided on the feed inlet 22. During the operation of the drying equipment, a certain pressure environment may be formed inside. The sealing cover 8 can prevent air from entering or leaving at will, which helps to maintain the stability of the internal pressure of the equipment. A stable pressure environment is very important for the normal operation of the equipment and the consistency of the drying effect. It can ensure that the hot air flows in the equipment according to the predetermined path and flow rate, thereby improving the drying efficiency and quality.

[0037] This utility model discloses the working principle and process of a fertilizer vibrating fluidized bed drying device. The fertilizer material to be dried is fed into the drying chamber 3 through the feed inlet 22 on the side of the upper cover 2. Multiple elastic elements 5 connecting the drying chamber 3 and the mounting base 1 work in conjunction with several vibration drive elements 6 installed on the drying chamber 3. The vibration drive elements 6 cause the drying chamber 3 to vibrate at a specific frequency and amplitude. This vibration is transmitted to the fertilizer particles in the drying chamber 3, causing the particles to exhibit a fluidized state similar to a fluid. The hot air device 4 heats the air and delivers it to the drying chamber 3. After entering the drying chamber 3, the hot air comes into full contact with the fertilizer particles in the fluidized state. Heat is transferred from the hot air to the surface of the fertilizer particles, causing the moisture on the particle surface to evaporate rapidly. The fully dried fertilizer material is discharged from the discharge funnel 32 of the drying chamber 3 under the action of vibration and gravity, completing the entire drying process.
