Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to a tower type vibrating mixed flow dryer. Background Art

[0002] Vibrating mixed flow dryer is a kind of equipment widely used in drying, cooling and dehumidification processes. It combines the principles of vibration and mixed flow, and can quickly and evenly dry wet materials. It has the advantages of fast drying speed, good drying effect, uniform material distribution and low energy consumption. It is widely used in the drying, cooling and dehumidification of materials in chemical, grain processing, pharmaceutical, metallurgical and other industries.

[0003] The existing vibrating mixed flow dryer has an unreasonable internal air duct design, which results in insufficient contact time between the hot air and the material, thus affecting the drying performance of the equipment. In addition, the drying range is too narrow, and the material can only be dried to a certain degree, which cannot meet the working conditions with different drying requirements. Utility Model Content

[0004] The main purpose of the utility model is to provide a tower type vibrating mixed flow dryer, which is used to solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A tower-type vibrating mixed flow dryer comprises a fixed steel frame, on which a drying tower is fixed. The drying tower comprises an upper cover, a drying section and a feeding section which are connected in sequence from top to bottom. The upper cover is provided with an air outlet and a feeding port, and a plurality of drying sections are connected to the lower side of the upper cover, and a drying assembly is arranged in the drying section. The drying assembly comprises a flexible bulk material plate on the upper side and a drying section on the lower side, and a plurality of feeding holes are arranged on the flexible bulk material plate, and a plurality of funnel-shaped drying sections are arranged under the flexible bulk material plate, and the diameter of the drying section decreases in sequence from top to bottom. A feeding hopper is arranged in the feeding section, and a discharge pipe is connected to the bottom of the feeding hopper. Air inlet pipes are inserted into the front, back, left and right sides of the feeding section, and the ends of the air inlet pipes pass through the feeding hopper and are connected to the drying section. A vibration source is arranged at the bottom of the feeding hopper.

[0007] Furthermore, the two adjacent drying sections are staggered to form a Z-shaped detour air duct. The Z-shaped detour air duct can extend the heat exchange time of the material and improve the drying performance of the equipment.

[0008] Furthermore, a spiral guide vane is arranged on the outer side of the drying section at the bottom of the drying assembly. The spiral guide vane can change the direction of the hot air blown in from the air inlet pipe, so that the hot air spirals up, prolonging the contact time with the material, thereby improving the drying performance of the equipment.

[0009] Furthermore, the vibration source is a vibration motor.

[0010] Furthermore, a curved pipe is connected to the end of the air inlet pipe, and the pipe opening of the curved pipe is arranged obliquely upward. The pipe opening arranged obliquely upward, in conjunction with the spiral guide vane, can make the hot air spirally rise in the drying section, prolonging the contact time with the material, thereby improving the drying performance of the equipment.

[0011] Furthermore, the flexible bulk material plate is configured in a conical shape. The feed holes on the flexible bulk material plate can allow air to pass through and materials to be mixed-flow dried.

[0012] Furthermore, the outer side of the fixed steel frame is coated with foam for heat preservation.

[0013] The utility model also includes other components that enable the tower vibrating mixed flow dryer to be used normally, and these devices or components all adopt conventional technical means in the field. In addition, the devices and components not limited in the utility model all adopt conventional technical means in the field, such as the vibration motor in this application. In the specific implementation process, the appropriate device or component model can be selected according to the specific working scenario.

[0014] The working principle of the utility model is: an air inlet pipe is inserted into the front, back, left, and right sides of the unloading section, and the end of the air inlet pipe is connected to a curved pipe with the pipe opening inclined upward, and with spiral guide vanes, Z-shaped circuitous air ducts, drying sections and other structures, the heat exchange time of the material is greatly extended and the drying performance of the equipment is improved. The number of drying sections can be adjusted according to the materials required by different drying processes to improve the breadth of materials to be processed.

[0015] Compared with the prior art, the utility model has the following beneficial effects: 1. Good drying performance and high drying efficiency. Prolonging the heat exchange time of materials and improving the drying performance of equipment. 2. Wide application range, meeting different degrees of drying needs.
