WLS420-13M Conveyor Model: WLS420-13M
Main performance technical requirements
1. The drive mechanism of the shaftless screw conveyor is composed of flameproof asynchronous motor, F series reducer, heavy load output disk and heavy load output shaft.
1）隔爆型异步电动机YBX3 160M-4、11kW、1460/min、防护等级IP55、防爆标志Ex dⅡB T4 Gb ( 1) Flameproof asynchronous motor YBX3 160M-4, 11kW, 1460 / min, protection class IP55, explosion-proof mark Ex dⅡB T4 Gb
2）减速机与螺旋壳体连接方便，必须加装过度连接装置，连接装置需配有重载荷推力调心滚子轴承、结构可靠、易更换维修，输出轴承载扭矩（最大载荷）5800N.m。 ( 2) The reducer is conveniently connected to the spiral housing. An over-connecting device must be installed. The connecting device must be equipped with heavy-duty thrust spherical roller bearings. The structure is reliable and easy to replace and maintain. m.
3）支撑轴承必须是推力调心滚子轴承。 ( 3) The support bearing must be a thrust spherical roller bearing.
4）结构紧凑，易于维护保养。 ( 4) Compact structure and easy maintenance.
2. The spiral blade material of the shaftless screw conveyor is formed by high-quality steel sheet rolling process. The diameter is 380, the blade thickness is 25mm, and the pitch is 370mm. The total length is 13000mm. In order to improve the combination and facilitate the transportation, the whole is divided into 3 sections. The first section is a power input section with a length of 3 meters (excluding the power drive mechanism), and the remaining two sections are standard sections with a length of 5 meters per section ( The standard section is interchangeable) It is articulated with 8.8 bolts and needs to be easily disassembled (the tank can be adjusted at any time during operation).
3. Conveyor housing is formed by Q235 steel plate rolling process (requires one-time forming and does not allow tailor welding). The thickness of the steel plate is 5mm. The flange connection is processed with flange thickness. The flange thickness is 12mm. Strength, flange appearance must be neat and beautiful.
4. The discharge port is designed at the motor end. The discharge port is a round hole of φ300mm. The discharge at the lower end of the discharge port can be rotated to ensure that there is no leakage when the discharge direction is changed.
5. The cover of the device has the same specifications, and it is installed with a mesh-like activity to facilitate the observation of the spiral operation and interchange with the cover.
6. The conveyor should be designed with a spiral body anti-warp device in the middle of the body, to avoid the spiral arch deformation caused by the cushioning of the material.
7, the conveyor support frame is "H" shape, add an oblique support on the "H" shape support frame in the direction of the channel to prevent the center of the tank from shifting.
8. Each section of the conveyor and the deceleration device are designed with lifting ears and lifting holes, etc. The design is convenient and reasonable to facilitate equipment lifting.
9. The liner is a wear-resistant nylon liner with a wall thickness of 10mm. (It is necessary to provide a qualified third party to perform the friction test and meet the requirements).
10. The cable trunking should be set at the conveyor body, and the drainage device should be set at the tail of the body.
3 /h。 11. The maximum conveying capacity of the screw conveyor is 18m 3 / h.
