Technical Field

[0001] The utility model relates to the technical field of fluidized bed dryers, in particular to a fluidized bed dryer with vibration screening. Background Art

[0002] Fluidized bed dryer is the main equipment for drying solid particulate matter. It is widely used in various fields such as chemical industry, petroleum, feed, medicine, etc. Fluidized bed drying has been widely developed and applied due to its advantages such as good heat transfer effect, uniform temperature distribution, various operation forms, adjustable material residence time, low investment cost and less maintenance workload.

[0003] During the fluidized bed drying process, bulk materials are placed on a perforated plate, and gas is transported from the bottom to suspend the material particles, just like boiling liquid, so that the material particles are fully in contact with the gas, and rapid heat and moisture transfer is carried out, so that the moisture of the material evaporates to achieve the purpose of drying. The equipment that uses this method to dry materials is called a fluidized bed dryer.

[0004] At present, most of the drying methods on the market are to manually intermittently pour the raw materials into the fluidized bed dryer for drying. However, due to the design structure of the dryer itself, the loading port is relatively high, which brings certain inconveniences to manual loading, and the loading is slow, which affects the subsequent processing. In addition, during the loading process, it is not convenient to vibrate and screen the materials, resulting in the accumulation of materials in one place and uneven feeding, which leads to the phenomenon that some raw materials are not dried or dried insufficiently, reducing the drying effect and thus reducing the drying efficiency of the device. Utility Model Content

To achieve the above purpose, the utility model provides the following technical solutions: a fluidized bed dryer with a vibration screen, comprising a fluidized bed dryer body, a mounting frame is fixed to the side wall of the fluidized bed dryer body, a feed pipe is fixedly sleeved in the middle of the mounting frame, the top of the feed pipe is connected to a feed hopper, the other end of the feed pipe is connected to a feed pipe, the bottom of the feed pipe is connected to a feed bin, reset springs are installed at the bottom of both sides of the feed bin, a slide is fixed to the bottom of the reset spring, a screen is fixedly connected in the middle of the slide, and a transmission mechanism is provided at the lower end of the slide for adjusting the slide to slide back and forth.

[0006] Preferably, a first motor is fixedly connected to the side end of the feed conveying pipe, and a spiral feed conveying blade is fixedly connected to the output end of the first motor.

[0009] Preferably, a support plate is fixed to the end of the fixed plate, a telescopic spring is installed at the end of the support plate, a connecting rod is sleeved on the end of the telescopic spring, an impact plate is fixedly connected to the end side of the connecting rod, a convex rod is installed on the side wall of the impact plate, the convex rod and the impact rod are arranged in the same horizontal plane, and the impact plate and the slide plate are in the same vertical plane.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

The specific selection calculation method adopts the existing technology in this field, so it is not repeated.

[0032] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a first motor 31 is fixedly connected to the side end of the material conveying pipe 3 , and a spiral material conveying blade 32 is fixedly connected to the output end of the first motor 31 .

[0033] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the screen 10 is placed in the lower bin 6 to slide horizontally up and down, the slide plates 8 are symmetrically distributed at both ends of the slide plate 8, and the side wall of the lower bin 6 is provided with a slide groove for facilitating the sliding of the slide plate 8.

[0034] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the transmission mechanism 9 includes a fixed plate 91 fixed to the side wall of the lower hopper 6, the side wall of the fixed plate 91 is fixedly connected to a second motor 92, the output end of the second motor 92 is fixedly connected to a transmission rod 93, the outer portion of the transmission rod 93 is sleeved with a turntable 94, and the surface of the turntable 94 is fixed with an impact rod 95.

[0035] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a support plate 96 is fixed to the end of the fixed plate 91, a telescopic spring 97 is installed at the end of the support plate 96, a connecting rod 98 is sleeved on the end of the telescopic spring 97, an impact plate 99 is fixedly connected to the end side of the connecting rod 98, a convex rod 910 is installed on the side wall of the impact plate 99, the convex rod 910 is arranged in the same horizontal plane as the impact rod 95, and the impact plate 99 is in the same vertical plane as the slide plate 8.

[0036] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a discharge port is provided on the side wall of the fluidized bed dryer body 1, and a blocking plate is slidably connected to the side wall of the fluidized bed dryer body 1, and the blocking plate fits the discharge port.

[0037] It should be noted that the fluidized bed dryer is provided with a discharge port for discharging materials, and the blocking plate is used to block the materials, which is the prior art in the art and will not be described in detail.

[0038] It should be noted that the specific models and specifications of the first motor 31 and the second motor 92 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0039] The use method and advantages of the utility model: When the fluidized bed dryer with vibration screening is working, the working process is as follows:

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the material bin for storing materials is connected to the feed hopper 4 through a conveying pipe, and the materials to be dried enter the feed pipe 3 through the feed hopper 4, and the first motor 31 is started to drive the spiral feed blade 32 to rotate, so that the materials are evenly conveyed to the discharge pipe 5 and leak into the discharge bin 6, so that the materials are evenly leaked into the fluidized bed dryer for drying, thereby realizing automatic feeding, improving work efficiency, and reducing labor costs;

[0041] The material is fed into the lower bin 6 through the lower feeding pipe 5 and accumulated on the surface of the screen 10. The second motor 92 is started to drive the transmission rod 93 to drive the turntable 94 to rotate. When the turntable 94 rotates, the impact rod 95 on its surface also rotates, and hits the convex rod 910 during the rotation. The convex rod 910 is forced to slide up and drive the impact plate 99 at the end to slide up and stretch the telescopic spring 97. When the impact plate 99 slides up, it hits the slide plate 8, and the slide plate 8 is forced to squeeze the spring. As the turntable 94 continues to rotate, the impact rod 95 is separated from the convex rod 910. After the convex rod 910 releases the impact force, the telescopic spring 97 is reset and contracted by its own elastic performance, and the impact plate 99 also slides down and breaks away from the impact on the slide plate 8. The reset spring 7 releases the pressure and drives the slide plate 8 to slide down. As the turntable 94 continues to rotate, the impact plate 99 hits the slide plate 8 one by one to achieve the effect of up and down vibration, so that the screen 10 vibrates and screens the material, so that the material can be evenly fed into the fluidized bed dryer body 1 for drying, so that the material is dried evenly and fully, and the drying efficiency is improved.
