Description

Technical Field

[0001] The utility model relates to the technical field of vibrating fluidized beds, and more specifically to a vibrating fluidized bed dryer. Background Art

[0002] Vibrating fluidized bed dryer, referred to as vibrating fluidized bed, is a new type of fluidized high-efficiency drying equipment suitable for drying granular and powdered materials. It has the advantages of easy operation, energy saving, and environmental protection. Vibrating fluidized bed is a new type of equipment that has been gradually developed and expanded in the past decade. It is becoming the main type of drying equipment. Vibrating fluidized bed is a new type of drying device that applies a vibration source with specific requirements to an ordinary fluidized bed dryer. This vibration source can be divided into electric motor method, electromagnetic induction method, crankshaft or eccentric wheel method, pneumatic or hydraulic method, etc. according to its excitation method.

[0003] When the existing vibrating fluidized bed dryer fluidizes and efficiently dries the material, the material is usually directly added into the dryer for drying. During this process, the thickness of the material added into the drying chamber is not easy to control. If the material is too thick, the hot air flow will not contact the material sufficiently, thus affecting the drying effect of the material. In view of this, we propose a vibrating fluidized bed dryer. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art, meet practical needs, and provide a vibrating fluidized bed dryer to solve the technical problem that the current vibrating fluidized bed dryer is not convenient for controlling the thickness of the material added into the drying chamber.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a vibrating fluidized bed dryer, comprising a vibrating fluidized bed body, a feeding port is arranged on one side of the top of the vibrating fluidized bed body, a discharging port is arranged on one side of the bottom of the vibrating fluidized bed body, a perforated plate is arranged inside the drying chamber of the vibrating fluidized bed body, a limited thickness structure is arranged inside the drying chamber of the vibrating fluidized bed body at the feeding port, the limited thickness structure comprises a first vertical plate, a second vertical plate and an electric push rod, the first vertical plate is arranged in the drying chamber of the vibrating fluidized bed body, the second vertical plate is slidably arranged on the side of the first vertical plate facing away from the feeding port, the electric push rod is arranged on the side of the first vertical plate facing the second vertical plate, and the piston end of the electric push rod is connected to the top of the second vertical plate;

[0006] A guide cover is arranged on one side of the first vertical plate facing the feed port, the inner cavity of the guide cover is arranged to be inclined downward, and the bottom side of the guide cover is aligned with the side of the discharge port.

[0007] During the use of the utility model, when the material is added into the drying chamber of the vibrating fluidized bed body from the feed port, the position of the second vertical plate on the first vertical plate can be adjusted up and down, so that the distance between the bottom of the second vertical plate and the orifice plate inside the drying chamber of the vibrating fluidized bed body reaches a suitable degree. At this time, the added material will pass through the thickness of the distance between the second vertical plate and the orifice plate under the shielding and limiting position of the second vertical plate, thereby achieving the effect of adjusting the thickness of the material inside the drying chamber of the vibrating fluidized bed body. Therefore, the utility model can avoid the problem of the material inside the drying chamber of the vibrating fluidized bed body being blocked by the second vertical plate. The situation that the material is too thick and affects the drying effect occurs, and when the material enters the main drying chamber of the vibrating fluidized bed from the feed port, the material will fall into the guide cover, and then the material will slide down along the guide cover. At this time, the material has a forward movement effect during the sliding process until the material slides out from the bottom of the guide cover. When the material slides out from the bottom of the guide cover, it will smoothly pass through the bottom of the second vertical plate and enter the orifice plate for drying, avoiding the direct accumulation of material on the second vertical plate and the occurrence of material jamming. Therefore, with the cooperation of the guide cover, it can be ensured that the material can pass through the bottom of the second vertical plate smoothly and quickly.

[0008] Preferably, an air inlet is arranged at the front side of the vibrating fluidized bed body, and an exhaust port is arranged at the top of the vibrating fluidized bed body.

[0010] Preferably, a sliding groove is provided on one side of the first vertical plate facing the second vertical plate, and a sliding block is slidably arranged inside the sliding groove, and the sliding block is connected and fixed to the second vertical plate.

[0011] Preferably, the slide groove and the slider are both T-shaped, and the sizes of the slide groove and the slider match.

[0012] Preferably, the top of the guide cover is a first opening area, and the side of the guide cover facing the second vertical plate is a second opening area.

[0013] Preferably, a connecting plate is arranged at the top of the guide cover and tilted toward one side of the first vertical plate, and the top of the connecting plate is fixedly connected to the first vertical plate, and the sides of the guide cover are in contact with the inner wall of the drying chamber of the vibrating fluidized bed body.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model designs a thickness limiting structure in the drying chamber of the vibrating fluidized bed body, and the thickness limiting structure is arranged at the feed port. Therefore, when the material is added into the drying chamber of the vibrating fluidized bed body from the feed port, the position of the second vertical plate on the first vertical plate can be adjusted up and down, so that the distance between the bottom of the second vertical plate and the orifice plate inside the drying chamber of the vibrating fluidized bed body reaches a suitable degree. At this time, the added material will pass through the thickness of the distance between the second vertical plate and the orifice plate under the blocking and limiting of the second vertical plate, thereby achieving the effect of adjusting the material thickness inside the drying chamber of the vibrating fluidized bed body, avoiding the situation that the material inside the drying chamber of the vibrating fluidized bed body is too thick and affects its drying effect, and solving the technical problem that the current vibrating fluidized bed dryer is not convenient for controlling the thickness of the material added into the drying chamber. Therefore, the utility model has the advantage of adjusting the material thickness inside the drying chamber of the vibrating fluidized bed body.

[0016] 2. The utility model also designs a guide cover on the first vertical plate. The inner cavity of the guide cover is tilted downward, and the side edges of the second vertical plate on the bottom side of the guide cover are aligned. Therefore, when the material enters the main drying chamber of the vibrating fluidized bed from the feed port, the material will fall into the guide cover, and then slide down along the guide cover. At this time, the material has a forward movement effect during the sliding process until the material slides out from the bottom side of the guide cover. After the material slides out from the bottom side of the guide cover, it will smoothly pass through the bottom of the second vertical plate and enter the orifice plate for drying operations, avoiding the direct accumulation of materials on the second vertical plate and the occurrence of material jamming. Therefore, with the cooperation of the guide cover, it can be ensured that the material can pass through the bottom of the second vertical plate smoothly and quickly.
