A pre-mixed abrasive water jet abrasive recycling system and its application method

Abstract

An abrasive recovery circulation system of pre-mixed abrasive water-jet. The abrasive recovery circulation system comprises a water trough (2), an overflow device (3), a vibrating screen (4), a slurry pump (5), and a water tank (6). A first sand adding opening (8) is provided on the top of the water tank (6), a stirring device is provided inside the water tank, and the bottom of the water tank is connected to an abrasive storage tank (15) by means of a compression feeding system and a high-pressure one-way valve (14) in sequence; a second sand adding opening (16) is provided on the top of the abrasive storage tank (15), and the bottom of the abrasive storage tank (15) is connected to a nozzle (1) and a high-pressure water pump (17) by means of a high-pressure water pipe (1.1). The abrasive recovery circulation system can achieve recycling and continuous feeding of abrasives under the condition of a single abrasive storage tank, the working performance is stable and controllable, and higher working pressure can be used.

Description

technical field [0001] The invention relates to the field of pre-mixed abrasive water jets, in particular to an abrasive recycling system for pre-mixed abrasive water jets and a method for using the same. Background technique [0002] Abrasive water jet technology is a widely used and powerful modern processing technology. Compared with the post-mixing abrasive waterjet system, the pre-mixing abrasive water jet system has a more reasonable abrasive mixing method, and the cutting capacity is several times that of the post-mixing under the same pressure parameter conditions. Although it has such advantages, there are some inherent problems in the pre-mixed abrasive water jet, mainly the abrasive pot, which restricts the current application. [0003] ①. Due to the high working pressure of the abrasive tank, it is difficult to realize continuous feeding. At present, there are two mature and mainstream solutions for this technical problem: one is to abandon continuous feeding a...

Problems solved by technology

Although it has such advantages, there are some inherent problems in the pre-mixed abrasive water jet, mainly the abrasive tank restricts the current application

[0003] ①. Due to the high working pressure of the abrasive tank, it is difficult to achieve continuous feeding

[0004] ②. In the case that the abrasive tank cannot achieve continuous feeding, generally only the abrasive tank with the largest possible volume can be used

However, the larger the volume of the abrasive tank, the more difficult it is to manufacture under the condition that the pressure resistance requirements remain the same, and the safety will also be affected

[0005] ③. Since abrasives have a service life, after the same batch of abrasives are used for many times in a row, the gradual loss of abrasives will directly affect the cutting performance and cutting accuracy

Obviously, because the cutting performance of new and old abrasives is different, the precision of cutting products will also fluctuate with the change of abrasives.

[0006] ④. The disadvantage of abrasive water jet is that the operating cost is high, and the main part of its cost composition is the abrasive cost

However, in both cases, the procedure is complex and costly
