Problems solved by technology

This kind of equipment has two main disadvantages: one is that for P36 with coarse sand grains, the electric field force is difficult to push the sand grains, and the sand planting is ineffective;
Taking the most advanced electrostatic sand planting equipment produced in Germany as an example, many foreign companies have imported this equipment with a cost of about 30 million yuan, but the quality is very unstable when producing P36 coarse abrasive cloth and sandpaper. The sand planting is invalid, and at the same time, the equipment cannot produce gravity sand planting abrasive cloth, sandpaper
In addition, the complex optical, mechanical, electrical, and hydraulic closed-loop correction system for sanding rollers often fails, which makes expensive insulating sanding belts frequently scrapped
What is even more unreasonable is that in this kind of equipment, the shakeout system, sand delivery system and support system are welded into a huge "consolidation" system, so it is difficult to transport, install, debug and maintain; , there are 3~4 sand sending rollers, and multiple sand sending rollers are more likely to cause deviation of the insulating sand feeding belt; the position of the shakeout system relative to the sand feeding system is also very important, but the two systems of the known electrostatic sand planting equipment The relative position of the two is fixed, and the relative position of the two cannot be optimized by adjustment; the insulation system in the known electrostatic sand planting equipment is also easily broken down by high voltage, etc. These problems in practice need to be solved

Abstract

The invention relates to ultrahigh voltage electrostatic sand-planting equipment comprising an electrostatic sand-planting hopper system, a gravity sand-planting hopper system, a sand conveying system, an ultrahigh voltage plate capacitor system, a support, sand cloth, an insulated sand conveying belt and the like. On the support, the insulated sand conveying belt is arranged through a power driven sand conveying roll and a tension and rectification roll, while the sand conveying system is arranged through an insulated support mechanism; a part on the insulated sand conveying belt, corresponding to the sand conveying system, is provided with a low voltage polar plate supporting and height adjusting mechanism; the support above the low voltage polar plate supporting and height adjusting mechanism is provided with the integral type ultrahigh voltage plate capacitor system; the sand cloth is arranged between the e low voltage polar plate supporting and height adjusting mechanism and the ultrahigh voltage plate capacitor system; and the gravity sand-planting hopper system and the electrostatic sand-planting hopper system are respectively arranged above the sand cloth and insulated sand conveying belt. Combining two different sand-panting modes, namely electrostatic sand planting and gravity sand planting, the ultrahigh voltage electrostatic sand-planting equipment can be used for electrostatic sand planting or gravity sand planting separately or simultaneously.

Description

technical field [0001] The invention relates to an ultra-static sand planting device, in particular to a sand planting device combining electrostatic and gravity modes. Background technique [0002] At present, the known electrostatic sand planting equipment uses the principle of static electricity to polarize sand grains such as silicon carbide or brown corundum in an electrostatic field, and uses the force of the electric field to push the polarized sand grains into the cloth or cloth coated with adhesive in advance. on paper. This equipment has two main disadvantages: one is that for P36 with coarse sand grains, the electric field force is difficult to push the sand grains, and the sand planting is ineffective; the other is that some occasions only need low-grade gravity sand planting abrasive cloth and sandpaper, which cannot be produced. Taking the most advanced electrostatic sand planting equipment produced in Germany as an example, many foreign companies have importe...
