Description

Technical Field

[0001] This utility model belongs to the technical field of traditional Chinese medicine processing equipment, and relates to a dryer, specifically a pill dryer with built-in fan. Background Technology

[0002] Pill dryers are suitable for granular materials that are difficult to dry evenly, tend to stick together, and require frequent stirring during the drying process. They are especially suitable for drying small honey pills, water-honey pills, and water pills made from traditional Chinese medicine.

[0003] Existing pill dryers generally consist of a casing, a rotating drum, a radiator, and a fan. The rotating drum is installed inside the casing, and a radiator is installed on the top of the casing to deliver hot air into the casing. A fan driven directly by a motor is installed at the back of the casing, and the fan's air intake is connected to the inside of the casing to draw in hot air.

[0004] When fans are operating, they inevitably generate noise. In current technology, fans are placed outside the casing, and this exposed placement exacerbates noise levels in the workshop, affecting workers' work. In addition, the external placement of the fan makes it easier for heat to be drawn from inside the casing to the outside, resulting in significant heat loss. This not only hinders energy consumption control but also affects the lifespan of the motor. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a built-in fan pill dryer with a scientific and reasonable structural design, which reduces noise pollution in the workshop, saves energy and reduces consumption, extends the service life of the motor, saves maintenance costs, and is easy to implement.

[0006] The technical problem solved by this utility model is achieved through the following technical solution:

[0007] A built-in fan type pill dryer includes a dryer body and a fan, characterized in that: the fan is a high-pressure fan, and an mounting plate is provided at the rear position inside the casing of the dryer body. The mounting plate, together with the rear wall and side wall of the casing, forms a mounting interlayer. The high-pressure fan is installed in the mounting interlayer through a bearing seat assembly. The high-pressure fan is driven by a motor belt located at the top of the casing.

[0008] Furthermore, the bearing housing assembly includes a bearing housing, an end cover, a connecting angle steel, screws, and nuts. A bearing is installed outside the drive shaft of the high-pressure blower, and a bearing housing is fitted outside the bearing. One end of the bearing housing extends from the rear wall of the casing and is fitted with an end cover by screws. The other end of the bearing housing is connected to the mounting plate by the cooperation of the connecting angle steel, screws, and nuts.

[0009] Furthermore, it also includes an air duct, which comprises a rectangular portion and a triangular portion. The outer edge of the rectangular portion is mounted on the inner side wall of the chassis, and an upwardly extending triangular portion is welded to the rear end of the rectangular portion. The air intake of a high-pressure blower is connected to the rear of the triangular portion.

[0010] The advantages and positive effects of this utility model are:

[0011] 1. This built-in blower pill dryer transforms the existing external blower design into an internal one. The high-pressure blower is enclosed in a casing, effectively isolating noise and reducing heat loss. Furthermore, the high-pressure blower is driven by a motor belt, preventing damage to the motor caused by the blower drawing hot air onto it.

[0012] 2. This utility model is scientifically and rationally designed, and has the advantages of reducing noise pollution in the workshop, saving energy and reducing consumption, extending the service life of the motor, saving maintenance costs, and being easy to implement. It is a highly innovative fan-built pill dryer. Attached Figure Description

[0018] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0019] like Figure 1 As shown, a blower-integrated pellet dryer includes a dryer body and a blower 2. Its innovation lies in that the blower is a high-pressure blower. An mounting plate 12 is provided at the rear position inside the casing 4 of the dryer body. The mounting plate, together with the rear wall 7 and the side wall of the casing, forms an mounting interlayer. The high-pressure blower is installed in the mounting interlayer through a bearing seat assembly. The air inlet of the high-pressure blower extends out from the mounting plate. The high-pressure blower is driven by a motor 1 located on the top of the casing by a belt.

[0020] The bearing housing assembly includes a bearing housing, an end cap 11, a connecting angle steel 8, screws, and nuts. A bearing is installed outside the drive shaft of the high-pressure blower, and a bearing housing is fitted around the bearing. The bearing housing includes a cylindrical portion 10 and a connecting portion 9 extending horizontally outward from the outer edge of one end of the cylindrical portion. One end of the cylindrical portion of the bearing housing extends from the rear wall of the casing and is fitted with an end cap by screws. The connecting portion of the bearing housing is connected to the mounting plate by the connecting angle steel, screws, and nuts. Figure 3 As shown, connecting angle steels are evenly distributed in a circular pattern on the mounting plate. Corresponding through holes are provided on the mounting plate, connecting angle steels, and bearing seat connection parts. The screws pass through the mounting plate, connecting angle steels, and bearing seat connection parts in sequence and are then fixed by nuts.

[0021] It also includes a duct 3, which is an outer shell with an internal cavity enclosed by sheet metal. It includes a rectangular part 6 and a triangular part 5. The outer edge of the rectangular part is installed on the inner side wall of the chassis. An upwardly protruding triangular part is welded to the rear end of the rectangular part. The air intake of the high-pressure blower is connected to the rear of the triangular part. The front opening of the rectangular part is used for air intake. The triangular part is used to introduce the intake hot air into the high-pressure blower. A pipe extending from the top of the chassis is connected to the air outlet of the high-pressure blower.

[0022] In order to integrate the fan, this utility model first designs the fan as a thin high-pressure fan, and secondly redesigns the casing and air duct. An installation compartment is left at the rear of the casing for installing the high-pressure fan, and an air duct is connected to the air inlet of the high-pressure fan.

[0023] This invention significantly reduces noise in the production workshop and ensures a safe working environment by redesigning the traditional external fan as an internal unit. Simultaneously, the internal design prevents excessive heat loss, eliminating the need for heat insulation in existing technologies and achieving energy conservation. Furthermore, the high-pressure fan is driven by a motor belt, preventing motor damage caused by the fan drawing hot air onto the motor.

[0024] Although embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
