Description

Technical Field

[0001] This invention belongs to the field of drying technology and relates to a vertical vibration dryer. Background Technology

[0002] Existing dryers on the market, such as drum dryers and flash dryers, have the following drawbacks: Drum dryers are long cylindrical structures with material and hot air entering at one end and material exiting at the other. Moist steam is drawn out by an induced draft fan. The main disadvantage is that even with a chain or other dispersing device inside the drum, the material cannot be fully dispersed within the drum, resulting in a small contact area with the hot air, low heat exchange efficiency, and a decreasing temperature gradient from one end of the drum to the other, which also decreases radially. Furthermore, the material cannot be fully mixed for heat exchange. Flash dryers, on the other hand, can fully disperse and exchange heat under the high-speed rotation of the blades. However, for materials with high moisture content, they are prone to sticking to the drum wall, leading to scorching. Flash dryers also require strong induced draft fan suction to operate, resulting in relatively high energy consumption, and the lower the inlet air temperature, the higher the energy consumption and the lower the drying effect. Summary of the Invention

[0003] The purpose of this invention is to provide a vertical vibration dryer that can solve the problems raised in the background art.

[0005] Preferably, the hot air assembly includes a blower and a hot air blower, the output end of the blower is connected to the input end of the hot air blower, and the hot air inlet of the hot air blower is connected to the input end of the spiral hot air duct to deliver hot air into the spiral hot air duct.

[0006] Preferably, the spiral material trough and the spiral hot air trough are in the shape of a conical tower, with the spiral diameter decreasing from bottom to top. During the upward vibration of the material, the fine material is mainly distributed at the bottom and the outer side of the bottom, while the clumps of material are mainly distributed at the top and the outer side. The outer side of the spiral material trough is mesh-like, which facilitates the overflow of large clumps of material, which fall into the lower spiral material trough and continue to participate in the upward vibration and drying.

[0007] Preferably, the vibration assembly includes a spring, which is mounted on a vibration bracket, and the vibration bracket is connected to the dryer housing via a flexible plate.

[0008] Preferably, the dryer casing is also connected to an induced draft fan, the input end of which is provided with at least two induced draft ducts, all of which extend into the interior of the dryer casing and are connected to the dryer casing. Each induced draft duct is provided with a throttle valve to control the air volume in the induced draft duct.

[0009] Preferably, the inlet end of the air duct is equipped with a bag filter and an intermittent air hammer, the intermittent air hammer blowing away the material from the bag filter in an intermittent manner.

[0010] Preferably, a fish-scale plate is provided at the bottom of the spiral material trough near the material outlet. The fish-scale plate facilitates the drying of materials without requiring them to pass through the hot air at the bottom, thereby increasing the material flow efficiency.

[0012] The positive and progressive effects of this application are as follows:

[0013] The vertical vibration dryer provided in this embodiment of the invention has the following advantages:

[0014] 1. This dryer features a vertically upward spiral material trough and a spiral hot air trough. The spiral hot air trough is located below the spiral material trough and is closed at the tail end or equipped with an adjustable air shut-off valve. A vibrating motor is located at the bottom or top of the dryer. Under the action of the vibrating motor, the material moves upward along the spiral material trough and flows out from the top. A mesh plate is installed at the bottom of the spiral material trough. The mesh plate is either grid-shaped or perforated, and hot air can be blown out from the mesh or holes. The hot air in the spiral hot air trough ensures that the material is dried with hot air of the same temperature throughout the entire spiral feeding process, from the feed end to the discharge end. The material vibrates in the spiral material trough, and clumps of material are broken up, allowing for full heat exchange with the hot air blown out from the bottom. The resulting water vapor is drawn out of the dryer by the induced draft fan through pipes on the outer side and top of the dryer.

During the upward vibration of the material, the fine material is mainly distributed at the bottom and the outer side of the bottom, while the clumps of material are mainly distributed at the top and the outer side. The outer side of the spiral material trough is mesh-like, which facilitates the overflow of large clumps of material, which fall into the lower spiral material trough and continue to participate in the upward vibration and drying.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] like Figure 1-5As shown, the present invention is a vertical vibrating dryer, including a vibrating support 1, which is flexibly connected to the dryer housing 2; a vibrating motor 3 and a vibrating assembly 31 are mounted on the vibrating support 1 below the dryer housing 2; a support 33 is provided on the vibrating support 1, and a spiral hot air trough 34 and a spiral material trough 35 are provided on the outer side of the support 33, with a mesh plate 39 between the spiral hot air trough 34 and the spiral material trough 35; the mesh plate 39 is connected to the spiral material trough 35; one end of the spiral hot air trough 34 is provided with a material inlet 21, and the other end is provided with a material outlet 22, and under the action of the vibrating motor 3, the material enters from the material inlet 21 and exits from the material outlet 22; one end of the spiral hot air trough 34 is provided with a hot air assembly, and the other end is provided with a wind-adjusting end 36.

[0025] This dryer has a vertically upward spiral material trough 35 and a spiral hot air trough 34. The spiral hot air trough 34 is below the spiral material trough 35 and is closed at the tail end or equipped with an adjustable air shut-off valve 36. There is a vibrating motor 3 at the bottom or top of the dryer. The material moves upward along the spiral material trough 35 under the action of the vibrating motor 3 and flows out from the top. The bottom of the spiral material trough 35 is equipped with a mesh plate 39, which is grid-shaped or perforated, and hot air can be blown out from the mesh or holes. The hot air in the spiral hot air trough 34 can ensure that the material is dried with hot air of the same temperature from the feeding end to the discharging end throughout the entire spiral feeding process. The material vibrates in the spiral material trough 35, and the clumps of material are broken up and fully exchanged with the hot air blown out from the bottom. The water vapor formed is drawn out of the dryer by the induced draft fan 4 through the pipes on the outer side and top of the dryer.

[0026] Vibration motor 3 can be installed at the bottom or top of the dryer, or at both the top and bottom, to increase the vibration intensity and facilitate the full dispersal and jumping of materials.

[0027] The hot air assembly includes a blower 6 and a hot air blower 61, both of which are mounted on a fixed bracket. The output end of the blower 6 is connected to the input end of the hot air blower 61, and the hot air inlet 38 of the hot air blower 61 is connected to the input end of the spiral hot air trough 34 to deliver hot air into the spiral hot air trough 34. The tail end of the spiral hot air trough 34 is sealed or equipped with an adjustable shut-off valve 36. During operation, the blower 6 and the hot air blower 61 are started, and hot air enters from the air inlet end of the spiral hot air trough 34 and is blown out through the mesh plate 39, so that hot air of the same temperature dries the material throughout the entire spiral feeding process.

[0028] The spiral material trough 35 and spiral hot air trough 34 form a conical tower structure, with the spiral diameter decreasing from bottom to top. During the upward vibration of the material, fine materials are mainly distributed at the bottom and the outer side of the bottom, while clumps of material are mainly distributed at the top and the outer side. The outer surface of the spiral material trough 35 is mesh-like, which facilitates the overflow of large clumps of material, which fall into the lower spiral material trough 35 to continue to participate in the upward vibration and drying, thereby improving the uniformity of the drying moisture content.

[0029] The vibration component 31 includes a spring, which is mounted on the vibration support 1. The vibration support 1 is connected to the dryer shell 2 via a flexible plate 32. The flexible plate 32 connects the vibration support and the dryer shell, forming a flexible connection and sealing surface, allowing the vibration support 1 to vibrate relatively freely without transmitting the vibration to the dryer shell 2. The flexible plate 32 connects the vibration support and the dryer shell 2, effectively reducing the impact of vibration on the entire dryer structure. The flexibility of the plate allows vibration to be absorbed and dispersed, avoiding the transmission and accumulation of vibration, thereby reducing the noise and vibration generated by the dryer during operation.

[0030] In this embodiment, the dryer housing 2 is also connected to an exhaust fan 4. The exhaust fan 4 is mounted on a fixed bracket. The exhaust fan 4 has at least two exhaust pipes 41 at its input end. The exhaust pipes 41 extend into the interior of the dryer housing 2 and are connected to the dryer housing 2. The exhaust pipes 41 are equipped with throttle valves 5 to control the air volume in the exhaust pipes 41.

[0031] The inlet end of the air duct 41 is equipped with a bag filter 42 and an intermittent air hammer 43. The intermittent air hammer 43 blows away the material on the bag filter 42 in an intermittent manner, effectively removing the material accumulated on the bag filter 42, extending the service life of the bag filter 42, and maintaining the stability of its filtration effect.

[0032] The upper part and top of the outer side of the dryer shell 2 are respectively provided with exhaust ducts 41. Multiple exhaust ducts 41 are combined into a large dehumidification duct and then connected to the exhaust fan 4. The port of the exhaust duct 41 located inside the dryer shell 2 is equipped with a bag filter 42 and an air gap hammer 43 for dust removal to ensure that the extracted gas meets the emission standards. At the same time, a throttle valve 5 is installed on the exhaust duct 41. According to the dryness and humidity requirements of the material, the throttle valve 5 is adjusted to control the air volume to achieve the dryness and humidity requirements of the material.

[0033] Preferably, a fish scale plate 351 is provided at the bottom of the spiral material trough 35 near the material outlet 22. The fish scale plate 351 facilitates the drying of materials without having to pass through the hot air at the bottom, thereby increasing the material flow efficiency.

[0034] Preferably, the outer shell of the dryer 2 is formed by joining two semicircles, which facilitates internal maintenance and cleaning. The outer layer of the dryer 2 is provided with a heat insulation layer. It can also increase the spiral length or connect multiple dryers in series according to the required dryness and humidity.

[0035] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
