Detailed ways

The structure of the multi-spray gun press-in type recycling sandblasting machine of the present utility model is shown in Figure 1 and Figure 2, including a sand valve 2, a pressure sand tank 4, an air control air circuit 9, a recovery system and two to four spray guns ;

The recovery system includes a vacuum pump 3, a dust collector 12, a screening separation cylinder 8 and a recovery head body 20, and the vacuum pump 3 and the screening separation cylinder 8 are sealed and connected with the dust collector 12 through a recovery rubber hose 11 respectively; 8 link to each other with the corresponding two to four recovery heads 20 on the spray gun through two to four recovery hoses;

The front end of the recovery head body 20 is provided with brushes 19 of different shapes. the

Two to four sandblasting recovery devices are installed on the outside of the screening and separating cylinder 8, and a sand screening device is installed inside. the

The recovery head body 20 includes a square nozzle 16 and a square sheath 18 of high-efficiency secondary air intake. the

The number of the sand outlet valve 2 is the same as that of the nozzles 16, and is used to accurately control the sand output of each nozzle with different sizes. the

The brush 19 is in the shape of an inner angle, an outer angle, an arc, a double column, a sharp angle, a truncated cone, a concave, a square, a rectangle, an outer arc, a plane or a shielding structure. the

The sandblasting machine also includes an electric control box 6 and a muffler 5, which are installed on the pressure sand tank 4 respectively. the

The recovery system is vacuumed by the vacuum pump 3 . the

The inside of the dust collector 12 is filtered by a filter element 13

The recovery head body 20 is also equipped with a switch 17 . the

Vehicle frame 14 and wheel 15 are installed on the bottom of described dust catcher 12, and the bottom of vehicle frame is equipped with wheel, and integral movement is convenient and flexible. the

Carry out paint removal, rust removal, and scale removal on the metal surface, strengthen the press-in type recycling sandblasting machine that can simultaneously recycle the sand material, use compressed air as the power, and form a high-speed sand flow through the nozzle to clean various metal surfaces , so that each surface has different degrees of cleanliness and roughness. the

The recovery system enables the ejected sand and the treated dirt and scale to be recovered immediately and simultaneously, and is screened and separated at the same time, so that the complete sand can be recycled and reused, while impurities and dust enter the dust cylinder. the

The machine meets the dust emission standard, meets the requirements of environmental protection, purifies the environment of the workplace, and is beneficial to the health of the operator. the

The nozzle is a square sandblasting nozzle or a square sheath with secondary air inlet and high efficiency. The working efficiency of the nozzle or sheath of this shape is higher than that of the traditional round hole nozzle and round hole sheath. the

The vacuum pump is the source of vacuum through which the sand is drawn back into the screen drum. the

The dirty gas sucked back by the vacuum pump is filtered by the dust collector and discharged from the filter element to ensure that the discharged gas is clean and meets environmental protection requirements. the

When working, first start the vacuum pump, so that the recovery system is all in a closed and airtight vacuum state, so that the ejected sand and processed dirt, dust, etc. are all sucked back through the recovery system, and the dirty gas passes through the dust collector. The filter element is filtered, and the clean and clean gas is discharged, and the gas emission meets the emission standard. the

When the sand material is sprayed out, the brush prevents the sand material from leaking out. Since there is a negative pressure airflow around the inner cavity of the brush, the external air is sucked into the recovery head through the gap of the brush, thus forming an external The sucked air plus the gas ejected during sandblasting, sand, dust, etc. are sucked into the screening and separating cylinder through the recovery hose connected to the recovery head body, so as to realize the recovery of sand, dust and impurities. the

Brushes of various shapes are installed on the front end of the recovery head body, and can be replaced arbitrarily to meet the needs of sandblasting on the surface of workpieces of different shapes. the

During the sandblasting process, the sand flowing out from the two to four sandblasting pipes at the bottom of the pressure sand tank enters the nozzle, is accelerated again and sprays to the working surface to be treated, because the brush has the ability to block the sand It has the effect of dissipating and dust, and also guides the external air to flow into the recovery head body along the edge of the brush and the gap of the brush, so that both sand and dust are sucked and recovered. In addition, the recovery head body and the working surface are in contact with the working surface through the brush, so there will be no phenomenon that the work piece will be sucked and not easy to move during work. The ejected sand is sucked into the screening and separating cylinder by the recovery hose in the inner diameter of the recovery head. After the recovered sand is screened in the screening and separating cylinder, the complete and reusable sand falls into the lower part of the screening and separating cylinder. In the silo, the dust and impurities are sucked into the dust box at the lower end of the dust collector through the recovery hose. Due to the screening of the screening and separating cylinder, the sand material can be recycled and reused. Since the vacuum pump communicates with the recovery system through the filter core, it can completely avoid the dust from being discharged into the atmosphere through the vacuum pump 3. the
