Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, specifically to a separator for stabilizing sand content. Background Technology

[0002] In the circuit board manufacturing process, the circuit boards need to be polished and cleaned. This polishing and cleaning process typically involves sandblasting the circuit boards using a sand-water mixture. To enable sand recycling, a separator is usually used to separate the sand from the sand-water mixture, removing impurities from the water and allowing for sand recycling. This also facilitates precise control of the sand-water mixture's blasting ratio, achieving accurate polishing. However, existing separators cannot completely remove chemical substances and fine sand from the sand-water mixture, and their control over sand coarseness and content is not stable enough. This can lead to sand getting stuck on the circuit boards during polishing, affecting work efficiency and quality, resulting in unsatisfactory performance. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies in the existing technology and provide a separator with stable sand content to improve grinding quality.

[0004] This utility model is achieved through the following technical solution:

[0005] A separator for stabilizing sand content includes a recovery mixing tank. A sand-water separation device is installed on the top of the recovery mixing tank. The sand-water separation device includes a plurality of sequentially connected cyclone sand-water separators. An inlet is provided on the outer side of the upper part of each cyclone sand-water separator. A drain outlet is provided on the top of each cyclone sand-water separator. An outlet is provided at the bottom of each cyclone sand-water separator. The drain outlet of the next cyclone sand-water separator is connected to the inlet of the previous cyclone sand-water separator through a first connecting pipe. The outlet is connected to the recovery mixing tank through a downpipe. A conduit communicating with the drain outlet is provided on the inner side of each cyclone sand-water separator. A first filter screen is provided at the bottom of the conduit, and a second filter screen is provided at the top of the conduit. A plurality of beads are provided between the first filter screen and the second filter screen.

[0006] Furthermore, a water pump is provided on the side of the recycling mixing tank. The inlet of the water pump is connected to the lower part of the recycling mixing tank through a second connecting pipe, and the outlet of the water pump is connected to the inlet of the cyclone sand-water separator at the beginning through a third connecting pipe.

[0007] Furthermore, a pressure gauge is installed on the third connecting pipe, and several of the cyclone sand separators are arranged sequentially from low to high pressure.

[0008] Furthermore, a stirring motor is installed on the top of the recycling mixing tank, and a stirring paddle is provided inside the recycling mixing tank. The motor shaft of the stirring motor is connected to the stirring paddle in a transmission manner.

[0009] Furthermore, a sandblasting device is provided at the rear upper part of the recycling mixing tank, and the rear side of the top of the recycling mixing tank is connected to the bottom of the sandblasting device.

[0010] Furthermore, a sandblasting pump is provided in front of the recycling mixing tank. The sand inlet of the sandblasting pump is connected to the lower part of the recycling mixing tank through a sand inlet pipe, and the sand outlet of the sandblasting pump is connected to the sandblasting device through a sand outlet pipe.

[0014] Furthermore, a water inlet pipe is connected to the side of the recycling mixing tank, and the water inlet pipe is equipped with a switch valve.

[0015] Compared to existing technologies, this utility model utilizes a sand-water separation device comprising several sequentially connected cyclone sand-water separators. The drain port of the next cyclone sand-water separator is connected to the inlet of the previous cyclone sand-water separator via a first connecting pipe. An inner conduit communicating with the drain port is provided within the cyclone sand-water separator. A first filter screen is located at the bottom of the conduit, and a second filter screen is located at the top. Several beads are positioned between the first and second filter screens. During operation, the sand-water mixture enters through the inlet of the cyclone sand-water separator. Under a certain pressure, the mixture rotates at high speed within the cyclone sand-water separator. The rotation generates centrifugal force, causing the sand-water mixture to... The denser sand flows downwards to the outlet of the cyclone sand-water separator, while the less dense water and chemicals flow upwards to the conduit of the cyclone sand-water separator. The beads between the first and second filter screens impact and wash away some fine sand, removing the chemicals adhering to the surface and causing it to fall back to the outlet, thus achieving the separation of the mixture.
