Problems solved by technology

Limited by its own structure, the service life of the fixed scraper is short and difficult to replace. Therefore, the cost of maintenance and replacement is high, which affects the operation rate of the equipment and greatly increases the production cost.
[0004] In addition, the scraper is hung on the upper bracket beam of the mixing barrel as a whole. Under the extrusion of the bottom material, the scraper frame will bend and deform and tilt away from the barrel wall, which cannot effectively clean the sticky material. More will affect the operation of the equipment; and after the material is squeezed by the side scraper on the barrel wall for a long time, the compaction will be harder and the cleaning difficulty will be further increased
In addition, during the actual replacement operation, it is necessary to stop the machine regularly to remove the internal materials of the mixing tank, observe the wear condition manually, and judge whether it needs to be replaced subjectively. On the one hand, it increases the difficulty of maintenance. The scraper affects the overall use of the equipment and the mixing effect
[0005] In view of this, it is urgent to optimize the structure of the existing mixing equipment to overcome the defects of high maintenance and replacement costs and affecting the equipment operating rate of the fixed scraper on the side wall

Embodiment 1

[0056] Embodiment 1, a mechanical probe is used, the front end of which is a retractable probe, and the other end of the probe is inserted inside the sensor, and an induction coil is wound inside. The change in the thickness of the hardened material will cause the depth of the probe inserted into the sensor to change, and then the self-inductance and mutual inductance will change on the induction coil, which will be converted into voltage or current change output by the circuit, so as to obtain the hardening of the side wall of the mixing tank 20. The thickness of the material is used to calculate the wear degree of the wear-resistant blade 1212. If the probe is retracted by 3mm, the data is transmitted to the control system through coil induction. After signal analysis, it is obtained that the material hardening thickness on the side wall of the mixing tank increases by 3mm, and the wear-resistant scraper 12 Wear 3mm. Furthermore, the measured data is transmitted to the contr...

Embodiment 2

[0057] Embodiment 2, a laser probe is used, the front end of which is a probe that can emit laser distance measurement. The change in the thickness of the compacted material will change the laser reflection distance of the probe, thereby obtaining the thickness of the plated material on the side wall of the mixing barrel 20, and calculating the wear-resistant blade. The degree of wear of 1212, such as the laser reflection distance of the probe is retracted by 3mm, and the data is transmitted to the control system through the reflection distance. After signal analysis, it is obtained that the material hardening thickness on the side wall of the mixing tank increases by 3mm, and the wear-resistant scraper 12 wears 3mm. Furthermore, the measured data is transmitted to the control system, and through program setting, when the material hardens to a certain thickness, the program responds with an alarm, prompting the staff to overhaul and replace the wear-resistant scraper 12 .

Abstract

The invention discloses a mixing device and a purging apparatus thereof. The purging apparatus comprises a scraper part arranged in a mixing barrel; the scraper part comprises a scraper frame and a wear-resistant scraper; and the scraper frame is axially fixedly arranged in a suspension manner, the wear-resistant scraper is provided with a plurality of scraper units which are successively arrangedon the scraper frame along the axial direction, and each scraper unit comprises a scraper basal body detachably connected with the scraper frame and a wear-resistant cutter blade arranged on the scraper basal body. According to the technical scheme, by virtue of the structural optimization, the maintenance and replacement cost can be effectively controlled, convenience in operation can be realized, and the device operation rate can be reliably ensured.

Description

technical field [0001] The invention relates to the technical field of mixing and stirring, in particular to a mixing device and a material cleaning device thereof. Background technique [0002] As we all know, most of the raw materials of products in metallurgy, chemical industry, building materials and other industries are mixtures, and the components in the mixture must be uniformly mixed to ensure product performance and quality. In particular, the raw materials of sintered pellets in the iron and steel industry are all powder materials, and the components of the raw materials vary greatly. In order to ensure product performance and quality, a powerful mixer with strong mixing capacity is generally used. Among them, the vertical intensive mixer is widely used because of its strong mixing ability, good mixing effect and high mixing efficiency. [0003] Existing vertical mixers mainly include components such as stirring paddles, mixing barrels, fixed supports and driving ...
