Description

Technical Field

[0001] This utility model relates to the field of vibrating fluidized beds, specifically a vibrating fluidized bed with a multi-stage baffle mechanism. Background Technology

[0002] A vibrating fluidized bed dryer, or simply vibrating fluidized bed, is a new type of high-efficiency fluidized bed drying equipment suitable for drying granular and powdery materials. It offers advantages such as ease of operation, energy saving, and environmental friendliness. In the fluidized bed dryer, material enters the machine through the feed inlet. Under the action of vibration, the material is thrown forward continuously along the horizontal fluidized bed. Hot air rises through the fluidized bed, exchanging heat with the wet material. After being dusted by a cyclone separator, the humid air is discharged through the exhaust fan (1:3 ratio). The dried material is discharged through the discharge inlet. It is suitable for drying and cooling powdery and granular materials in industries such as chemical, pharmaceutical, food, dehydrated vegetables, grain, and mining. The material enters the machine through the feed inlet and, under the action of vibration, is thrown forward continuously along the horizontal direction. Hot air rises through the fluidized bed, exchanging heat with the wet material. After being dusted by a cyclone separator (or pulse-jet bag filter), the humid air is discharged through the exhaust fan. The dried material is discharged through the discharge outlet and then collected and packaged.

[0003] According to publicly available patent CN209068857U, a multi-stage baffle device for a vibrating fluidized bed is disclosed. It includes several sets of baffle devices arranged on the vibrating fluidized bed. Each set of baffle devices includes a positioning device, a baffle execution device, and a sieve plate. The positioning device includes a handle and a positioning plate. The handle is located on the shaft of the positioning plate and the baffle execution device. The positioning plate is located on the outer side of the vibrating fluidized bed. The baffle execution device includes a shaft, a bushing, a baffle plate, a shaft seat, and a cover plate. The shaft is located on the bed. One end of the shaft has a shaft seat and a cover plate, and the cover plate is located on the shaft seat. The other end has a bushing and a handle. The baffle plate is located on the shaft, and a sieve plate is located below the baffle plate on the bed. In the process of realizing this utility model, the inventor discovered that... The existing technology suffers from at least the following unresolved problems: Material is divided into segments using baffles, and shaft rotation is controlled by handles and positioning plates. This shaft rotation drives the baffles to rotate along the shaft, controlling the height of the powder layer in each segment. It can also control the residence time of each segment in the fluidized bed to precisely control the discharge moisture content and temperature. However, traditional multi-segment baffles require independent adjustment during use, making adjustment cumbersome. Furthermore, in applications requiring balanced airflow distribution, the sealed baffles prevent some airflow from passing through, increasing airflow disturbance to the material and affecting the uniformity of fluidization. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a vibrating fluidized bed with a multi-segment baffle mechanism to solve the technical problem that the current multi-segment baffles need to be adjusted independently, which makes the adjustment of the baffles quite troublesome.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a vibrating fluidized bed with a multi-segment baffle mechanism is designed, including multiple sets of baffle components and synchronization components installed on the vibrating fluidized bed. Each set of baffle components includes a baffle plate, a rotating shaft and two connecting blocks. The two connecting blocks are connected to the top two sides of the baffle plate. The rotating shaft is rotatably connected to the two sides of the inner cavity of the vibrating fluidized bed, and the two connecting blocks are rotatably sleeved on the outside of the rotating shaft.

[0006] The synchronization component includes connecting plates installed on both sides of one end of the inner cavity of the vibrating fluidized bed. A worm gear is rotatably connected between the two connecting plates. A worm wheel is fixedly connected to the outer side of the rotating shaft on each set of the baffle assembly. The worm gear meshes with the worm wheel, and one end of the worm gear rotatably passes through the connecting plate and is located on the outer side of the connecting plate.

[0007] Preferably, each set of the baffle assembly has multiple through holes on its baffle plate, the multiple through holes on each set of the baffle plate are evenly distributed, and the multiple through holes on each set of the baffle plate correspond to each other.

[0008] Preferably, an adjustment groove is provided on both sides of one end of the baffle plate, and an adjustment block is slidably connected in each of the two adjustment grooves. A baffle plate is connected between the two adjustment blocks, and the baffle plate moves against the baffle plate. A lead screw is rotatably connected between the upper and lower sides of the inner cavity of one of the adjustment grooves, and the adjustment block is threaded on the outside of the lead screw. The top of the lead screw rotatably passes through the adjustment groove and is positioned on the top of the baffle plate.

[0009] Preferably, a sealing gasket is installed at one end of the baffle plate near the baffle plate, and the sealing gasket is a high-temperature resistant gasket.

[0010] Preferably, the size of the baffle plate is the same as the outer dimensions of the plurality of through holes on the baffle plate.

[0011] Preferably, the lead angle of the worm is smaller than the friction angle of the worm wheel contact.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model combines a worm gear, worm wheel, rotating shaft, connecting block, baffle plate, and connecting plate. By rotating the worm gear, the worm wheel rotates, which in turn rotates the rotating shaft, causing the baffle plate to rotate along the shaft. This adjusts the distance between the bottom of the baffle plate and the sieve plate on the vibrating fluidized bed, thereby controlling the height of each powder layer in the vibrating fluidized bed. Since the worm gear meshes with each set of worm wheels, the rotation of the worm gear can synchronously adjust the distance between the bottom of the baffle plate and the sieve plate on the vibrating fluidized bed, solving the problem that existing multi-section baffle plates require independent adjustment, making baffle plate adjustment cumbersome.

[0014] 2. This utility model combines a through hole, an adjusting groove, an adjusting block, a lead screw, and a baffle plate. When there is no need to balance the airflow distribution, turning the lead screw moves the baffle plate to the outside of the through hole, thereby blocking the through hole. When there is a need to balance the airflow distribution, turning the lead screw in the opposite direction moves the baffle plate above the through hole. Thus, when the vibrating fluidized bed is in use, some of the internal airflow can pass through the through hole, thereby reducing the disturbance of the airflow to the material, improving the uniformity of material fluidization, and facilitating easy switching according to the material fluidization requirements, making it highly applicable.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A vibrating fluidized bed with a multi-stage baffle mechanism, see [link / reference] Figures 1 to 4The system includes multiple sets of baffle assemblies and synchronization assemblies installed on the vibrating fluidized bed 1. Each set of baffle assemblies includes a baffle plate 22, a rotating shaft 2, and two connecting blocks 21. The two connecting blocks 21 are connected to the top two sides of the baffle plate 22. The rotating shaft 2 is rotatably connected to both sides of the inner cavity of the vibrating fluidized bed 1, and the two connecting blocks 21 are rotatably sleeved on the outside of the rotating shaft 2. The synchronization assembly includes connecting plates 3 installed on both sides of one end of the inner cavity of the vibrating fluidized bed 1. A worm gear 31 is rotatably connected between the two connecting plates 3. A worm wheel 32 is fixedly connected to the outside of the rotating shaft 2 on each set of baffle assemblies. The worm gear 31 meshes with the worm wheel 32. One end of the worm gear 31 rotatably passes through the connecting plate 3 and is located on the outside of the connecting plate 3.

[0022] During operation, the worm gear 31 is rotated to drive the worm wheel 32 to rotate, which in turn drives the shaft 2 to rotate along the shaft 2. This adjusts the distance between the bottom of the baffle plate 22 and the sieve plate on the vibrating fluidized bed 1, thereby controlling the height of each powder layer in the vibrating fluidized bed 1. Since the worm gear 31 meshes with each set of worm wheels 32, the rotation of the worm gear 31 can synchronously adjust the distance between the bottom of the baffle plate 22 and the sieve plate on the vibrating fluidized bed 1. This solves the problem that existing multi-section baffle plates 22 need to be adjusted independently, making the adjustment of the baffle plates 22 quite troublesome.

[0023] For details, see Figure 1 and Figure 4 Each set of baffle plates 22 has multiple through holes 23, which are evenly distributed and correspond to each other. Each baffle plate 22 has two adjusting grooves 44 on both sides of one end. Adjusting blocks 42 are slidably connected within each adjusting groove 44. A baffle plate 4 is connected between the two adjusting blocks 42, and the baffle plate 4 moves against the baffle plate 22. A lead screw 43 is rotatably connected between the upper and lower sides of the inner cavity of one of the adjusting grooves 44, and the adjusting block 42 is threaded onto the lead screw 43. On the outside of 3, the top of the lead screw 43 rotates through the adjusting groove 44 and is placed on the top of the baffle plate 22. When there is no need to balance the airflow distribution, the baffle plate 4 is placed outside the through hole 23 by turning the lead screw 43, thereby blocking the through hole 23. When there is a need to balance the airflow distribution, the baffle plate 4 is placed above the through hole 23 by turning the lead screw 43 in the opposite direction. Thus, when the vibrating fluidized bed 1 is in use, some of the airflow inside can pass through the through hole 23, thereby reducing the disturbance of the airflow to the material, improving the uniformity of material fluidization, and making it easy to switch at will according to the needs of material fluidization, which is more applicable.

[0024] It is worth noting that, see Figure 3A sealing gasket 41 is installed at one end of the baffle plate 4 near the baffle plate 22. The sealing gasket 41 is a high-temperature resistant gasket. The size of the baffle plate 4 is the same as the outer size of the multiple through holes 23 on the baffle plate 22. By setting the sealing gasket 41, the sealing performance of the connection between the baffle plate 4 and the baffle plate 22 is increased, and gaps are avoided between the baffle plate 4 and the baffle plate 22 when the baffle plate 4 blocks the through holes 23. This allows for a balanced airflow distribution when there is no need to balance the airflow distribution.

[0025] It is worth noting that, see Figure 2 The lead angle of the worm 31 is smaller than the friction angle of the worm wheel 32 contacting the worm 31. This provides a self-locking function for the meshing of the worm 31 and the worm wheel 32, preventing the worm wheel 32 from driving the worm 31 to rotate. This also fixes the angle of the baffle plate 22 after rotation adjustment, preventing the baffle plate 22 from moving after rotation adjustment and causing different heights of each powder layer in the vibrating fluidized bed 1, which would affect the fluidization effect of the material.

[0026] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
