Description

Technical Field

[0001] This utility model relates to the field of paddle dryer technology, specifically a cleaning and maintenance device for paddle dryers. Background Technology

[0002] A paddle dryer is a low-speed agitation dryer that uses an internal stirring paddle to ensure that wet materials come into full contact with the heat carrier and heated surfaces, thus achieving the drying purpose. It is typically horizontal, with two or four shafts. Paddle dryers are classified into hot air type and conductive type.

[0003] Existing paddle dryers require disassembly of the internal paddles for cleaning and maintenance, or manual cleaning by workers, resulting in long waiting times and high labor costs. There is no automatic cleaning and maintenance device, so a device that can clean the paddles instantly is needed.

[0004] Therefore, it is necessary to design a cleaning and maintenance device for paddle dryers that is both practical and easy to maintain. Summary of the Invention

[0005] The purpose of this invention is to provide a cleaning and maintenance device for a paddle dryer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleaning and maintenance device for a paddle dryer, comprising a dryer, wherein paddles are provided inside the dryer, a telescopic cover is provided above the dryer, support columns are provided on both sides of the dryer, a first cylinder is provided above the support columns, and a rack is provided at the rod end of the first cylinder.

[0007] According to the above technical solution, a controller is slidably connected to the outer side of the rack, a gear is provided on the inner side of the controller, a motor is provided on the outer side of the gear, and the gear and the rack are meshed together.

[0008] According to the above technical solution, a second cylinder is provided inside the controller, a support frame is provided at the rod end of the second cylinder, and a surrounding frame is provided above the support frame.

[0009] According to the above technical solution, a slide rail is provided on the inner side of the enclosure frame, a lifter is provided on the inner side of the slide rail, a first rotator is provided on the inner side of the lifter, and a first roller brush is provided at the output end of the first rotator.

[0010] According to the above technical solution, a support rod is provided on the inner side of the enclosure frame, a left telescopic device is provided on the inner side of the support rod, a slide plate is provided at the telescopic end of the left telescopic device, a second rotator is provided at the bottom of the slide plate, a second roller brush is provided at the bottom of the second rotator, a right telescopic device is provided on the inner side of the support rod, and a second set of cleaning brushes is provided at the telescopic end of the right telescopic device.

[0011] According to the above technical solution, a blower is provided on the front side of the support rod.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] (1) By setting a first roller brush, since the first roller brush is used to brush off surface impurities, it does not need to follow the up and down movement of the enclosure frame. Therefore, the lifting device can be controlled to move in the opposite direction relative to the second cylinder on the slide rail, so as to keep the first roller brush always on the blade surface. Then the first rotator opens, rotates the first roller brush to clean the surface impurities, and at the same time, the internal cleaning liquid is sprayed to assist in cleaning.

[0014] (2) With the support rod provided, the left telescopic device and the right telescopic device need to control the position of the cleaning components on both sides so that they can be inserted into the inner gap of each blade. Then the second rotator starts to drive the second roller brush to rotate. The blades and inner wall are cleaned by spraying cleaning liquid and rotating in conjunction with the second cylinder. The second set of cleaning brushes is the same.

[0015] (3) By setting up a controller, the motor is fixed on the outside of the controller. After starting, it can drive the gear to rotate. When the gear rotates, it will move forward on the rack and drive the controller to move forward. When the rack descends to the appropriate position, the second cylinder starts and drives the surrounding frame to move up and down by repeatedly extending and retracting the air rod, thereby driving the inner cleaning device to clean the blades and the inner wall of the dryer.
