" Maquina Jateadora de granalha": máquina esta caracterizada pela a sustentabilidade por razões de uso mínimo de material para a sua construção e de grãos para o seu funcionamento; compreende em um corpo cúbico 1 de dimensões que variam conforme necessidade dos clientes, ou seja, a necessidade de sua aplicação; este cubo 1 é apoiado em uma base inclinada 2 de um range 42,5° a 48° com os chanfros a 45° na parte frontal alinhado com duto de passagem de granalha 7 formando um único plano impedindo os grãos de aço acumularem e se estacionarem, o duto de passagem de granalha 7 possui em sua base um rasgo retangular de 35 mm de altur¾»para a passagem de granalha e ar, e sua parte superior é de dimensão maior que a inicial para criar um aumento de área e garantir a diferença de pressão quando acionado o motor 3 de 5 cv e 3750 rpm. Outro dispositivo para garantir o levantamento do fluido (granalha neste caso) é o posicionamento do disco da turbina 4 e a palheta da turbina 6 em relação ao cabeçote 8, para que o funcionamento do sistema seja em um fluxo inicial de sentido inverso para que o ar retire as granalhas de aço que estão depositadas no inicio do duto 7 obstruindo a passagem, após iniciada e ocorrer a retirada do material o fluxo reverte para o sentido correto criando um vácuo para sucção da granalha, para garantir o levantamento da granalha e a sua eficiência; ainda existem outros recursos tecnológicos para dar o seu bom funcionamento, que são ângulos e diferença de polígonos (polígonos estes: entrada de granalha retangular, inicio de duto de passagem de granalha 7 de forma Trapezoidal, no inicio da subida da granalha no duto 7 transforma-se em formato triangular, desembocando no disco da turbina 4 + palheta da turbina 6 em forma de um quadrado), estas formas de polígono diferentes são para criar uma grande turbulência no deposito inferior do duto 7 , fazendo com que crie uma grande turbulência (vortex) para que a granalha tenha possibilidade de subir até o disco da turbina 4 + palheta da turbina 6, fechando o ciclo de fluxo do ar+ granalha também existe uma entrada de ar abaixo da base do motor 3 na parte traseira do cubo que diminui o caminho percorrido pelo ar e após a passagem do ar pelo disco turbina 4 + palheta da turbina 6 (que gira em sentido horário) emperra a granalha pro tudo 7 e também passa por baixo do cesto rotativo 9 que gira no sentido anti-horário e sai pelo lado esquerdo da maquina na parte traseira pelo duto de saída de ar 17; este ciclo de ar permite o jateamento continuo das peças sem ocasionar resultante na turbulência interna. Para a eficiência da limpeza e a qualidade de superfície da peça existe uma relação junto ao cesto 9 paralelo com a base da máquina e com 30 ciclos/min. "Shot Blasting Machine": machine is characterized by sustainability for reasons of minimum use of material for its construction and grain for its operation; comprises in a cubic body 1 of dimensions that vary according to customer needs, ie the need for its application; This hub 1 is supported on an inclined base 2 of a range 42.5 ° to 48 ° with the 45 ° chamfers on the front aligned with shot-through duct 7 forming a single plane preventing steel grains from accumulating and parking , the shot-through duct 7 has at its base a 35 mm high rectangular slot for the shot and shot, and its upper part is larger than the initial to create an increase in area and to ensure the difference of pressure when the 5 hp 3750 rpm 3 engine is started. Another device for ensuring fluid lift (shot in this case) is the positioning of the turbine disc 4 and the turbine vane 6 relative to the head 8 so that the system will operate in an initial reverse flow direction so that the remove the steel shot that is deposited at the beginning of the duct 7, blocking the passage, after the material has started and the material is removed, the flow reverts to the correct direction creating a vacuum for the shot suction, to guarantee the shot lifting and its removal. efficiency; There are still other technological resources to make it work, which are angles and polygon difference (polygons these: rectangular shot inlet, beginning of shotpipe 7 of trapezoidal shape, at the beginning of rising shot in shot 7 triangular in shape, leading to turbine disc 4 + turbine blade 6 in the form of a square), these different polygon shapes are to create a large turbulence in the lower deposit of the duct 7, causing it to create a large turbulence ( vortex) so that the shot can rise up to the turbine disc 4 + turbine vane 6, closing the air flow cycle + shot also has an air inlet below the motor base 3 at the rear of the hub that decreases the air path and after air passing through the disc turbine 4 + turbine vane 6 (turning clockwise) clamps the shot to everything 7 and also goes under the basket anti-clockwise turn 9 and exits from the left side of the machine at the rear through the air outlet duct 17; This air cycle allows continuous blasting of the parts without resulting in internal turbulence. For cleaning efficiency and the surface quality of the workpiece there is a relation near basket 9 parallel to the machine base and 30 cycles / min.
Para a limpeza dos grãos de aço utilizamos um aspirador de pó convencional onde o importante é o posicionamento da fixação do duto 21, com isso garante a sua eficiência pois o pó gerado pelo atrito ou impacto da granalha com as peças não se deposita junto as peças , evitando o risco de incêndio e não dá contaminação na peça.
For cleaning the steel grains we use a conventional vacuum cleaner where the important thing is the positioning of the duct fixture 21, thus ensuring its efficiency because the dust generated by the friction or impact of the shot with the pieces does not deposit with the pieces. , avoiding the risk of fire and does not give contamination in the part.
