A steel shot and paint ash separation device for production workshops Technical Field
[0001] This utility model relates to the field of steel sand and paint ash separation technology, specifically to a steel sand and paint ash separation device for production workshops. Background Technology
[0002] Steel shot (metal abrasive) and paint ash (spraying waste) need to be efficiently separated to achieve steel shot recovery (80-95% recovery rate) and harmless treatment of paint ash. However, traditional vibrating screen separation methods are prone to screen clogging leading to downtime, or centrifugal separation has the problem of excessive energy consumption. In addition, paint ash may contain harmful substances, and direct discharge does not meet environmental standards, so filtration or collection systems may be necessary.

An air purification filter is installed at the top of the paint dust purification device by screws. The bottom output port of the cyclone separator is connected to a steel shot collection tank. The bottom output port of the paint dust purification device is connected to a paint dust collection tank.
[0007] By adopting the above technical solution, the steel sand and paint ash separation device in the production workshop can efficiently separate steel sand and paint ash, realizing the recycling of steel sand and the harmless treatment of paint ash.
[0008] Specifically, an inclined pipe is provided between the horizontal conveying pipe and the steel shot collection trough, and a valve B is provided on the inclined pipe.
[0009] By adopting the above technical solution, the function of valve B is to control the air flow rate in the cyclone separator and prevent excessive flow rate from causing the intake of too much steel shot.
[0010] Specifically, a baffle A is installed inside the horizontal conveying pipe and at the inlet of the inclined pipe, and a baffle B is installed inside the steel shot collection trough and at the outlet of the inclined pipe by screws.
[0011] Specifically, the top side of the paint dust purification device is connected to an air suction pipe and an air suction fan is installed on the air suction pipe.

[0013] By adopting the above technical solution, valve A serves to collect the paint dust after the paint dust purification device is opened and after the device has finished operating.
[0014] The beneficial effects of this utility model are:
[0015] (1) The steel sand and paint ash separation device for production workshop described in this utility model is as follows: the steel sand and paint ash mixture is added into the feeding hood and enters the cyclone separator through the horizontal conveying pipe; a cylindrical filter element is installed at the air outlet of the cyclone separator to separate the mixture into a mixture of paint ash, small-diameter steel sand and a small amount of paint ash; the mixture of paint ash and a small amount of steel sand in the mixture enters the horizontal conveying pipe through the inclined pipe of the steel sand collection tank below the separator and enters the cyclone separator again for separation, while the steel sand enters the steel sand collection tank below.
[0016] (2) The steel sand paint ash separation device for production workshop described in this utility model, after the paint ash is screened by the cyclone separator, enters the final air purification filter. After being screened by the filter, harmless and pollution-free air is released into the atmosphere, and the paint ash is concentrated in the paint ash collection tank, thus completing the steel sand paint ash separation process.

A cyclone separator 3 is provided at one end of the feeding hood 2. The feeding hood 2 is bolted to the top of the working platform 1, and the output port of the feeding hood 2 is connected to the cyclone separator 3 through a horizontal conveying pipe 15. A cylindrical filter element 4 is bolted to the top of the cyclone separator 3.
[0023] One end of the cyclone separator 3 is equipped with a paint dust purification device 5. The top output port of the cyclone separator 3 is connected to the input port of the paint dust purification device 5 through a connecting bend 16. An air purification filter 11 is installed at the top of the paint dust purification device 5 by screws. The bottom output port of the cyclone separator 3 is connected to a steel sand collection tank 10, and the bottom output port of the paint dust purification device 5 is connected to a paint dust collection tank 9.
[0024] In use, the steel sand and paint ash separation device in the production workshop efficiently separates steel sand and paint ash, realizing the recycling of steel sand and the harmless treatment of paint ash.

[0026] When in use, valve B8 is used to control the airflow rate inside the cyclone separator 3 to prevent excessive flow rate from causing too much steel shot to be sucked in.
[0027] For example, as shown in Figures 1 and 2, the present invention further includes a baffle A12 provided inside the horizontal conveying pipe 15 and at the inlet of the inclined pipe 14, and a baffle B13 installed by screws inside the steel shot collection trough 10 and at the outlet of the inclined pipe 14.

A cylindrical filter element 4 with a filter hole diameter smaller than that of the steel shot is installed at the air outlet of the cyclone separator 3 to separate the mixture into a mixture of paint ash, small-diameter steel shot, and a small amount of paint ash. The mixture of paint ash and a small amount of steel shot enters the horizontal conveying pipe 15 through the inclined pipe 14 of the steel shot collection tank 10 below the separator and is re-entered into the cyclone separator 3 for separation, while the steel shot enters the steel shot collection tank 10 below.
[0034] After being filtered by the cyclone separator 3, the paint dust enters the final air purification filter 11. After being filtered by the filter, harmless and pollution-free air is released into the atmosphere, and the paint dust is concentrated in the paint dust collection tank 9, completing the steel sand and paint dust separation process. The function of baffles A12 and B13 is to minimize the amount of steel sand sucked in during circulation.
