This invention discloses a high-speed centrifugal water injection purification and dewatering method for marine silica sand. This invention relates to the field of silica sand purification technology and includes the following steps: activating the silica sand; sieving the activated silica sand to remove impurities; mechanically grinding the sieved silica sand; treating the ground silica sand with centrifugal water injection, using centrifugal force combined with water injection to remove chloride ions and harmful substances from the silica sand; and dewatering the treated silica sand to obtain finished silica sand. By combining activation treatment, mechanical grinding, and centrifugal water injection purification, chloride ions and impurities such as shells and mud can be effectively removed from the silica sand. This process adopts a step-by-step treatment method: first, activation loosens the colloids on the surface of the silica sand; then, mechanical grinding breaks down the colloidal layer structure; and finally, centrifugal force combined with water injection separates the soluble salts from the silica sand, achieving deep purification of the silica sand.

This utility model relates to the field of electro-deionization water purification technology and discloses an electro-deionization water purification device, including a shell assembly. A rubber diaphragm is fixedly installed on the upper inner wall of the shell assembly, an electrode assembly is installed on the outer wall of the shell assembly, a ring-shaped sterilization assembly is installed on the lower inner wall of the shell assembly, and an auxiliary assembly is installed at the bottom of the shell assembly. The electrode assembly facilitates the directional migration of ions in the water under the action of an electric field, with cations moving towards the cathode and anions moving towards the anode. This ion migration allows for the effective removal of ions from the water, thereby achieving deep water purification. Furthermore, the rubber diaphragm allows it to regain its adsorption capacity, ensuring stable operation of the device over a long period and reducing the frequency and cost of chemical regeneration.

This application discloses a multi-angle purification and air supply device for central air conditioning, relating to the field of air conditioning. It includes an air supply duct and a mounting plate fixed to one side of the air supply duct. Multiple air outlets are formed on the surface of the mounting plate, and an air guide mechanism is installed inside each air outlet, partially located inside the air supply duct. An air inlet is formed at the end of the air supply duct away from the mounting plate. A filter module is fixedly inserted into the side of the air supply duct near the air inlet. Inside the filter module, a pre-filter, a HEPA filter, and an activated carbon filter are arranged sequentially along the airflow direction. A centrifugal fan and an axial fan are fixedly installed inside the air supply duct near the mounting plate. This application uses a motor to drive a spur gear to rotate, causing the gear plate to move and the universal joint structure to deflect at an angle, thereby causing the air guide plate to rotate around the rotating rod, achieving multi-directional flexible adjustment of the air supply angle to meet the needs of different scenarios.

This invention discloses an air particulate matter separation device and method. The device includes a fan, a purified water chamber, and a multi-stage separation chamber. A filter element is installed within the multi-stage separation chamber. The fan blows air carrying dust particles into the multi-stage separation chamber, causing the dust particles (calcium carbonate particles) to be filtered onto the filter element. The multi-stage separation chamber is connected to a first gas separation mechanism, which in turn is connected to the purified water chamber. The purified water chamber stores distilled water. The first gas separation mechanism separates carbon dioxide from the air and inputs the carbon dioxide into the purified water chamber, converting the distilled water into carbon dioxide-containing water. The purified water chamber is connected to the multi-stage separation chamber, and the filter element is rinsed using this carbon dioxide-containing water. During physical rinsing, carbon dioxide, water, and calcium carbonate react to form calcium bicarbonate dissolved in the water, effectively removing dust particles adhering to the filter element, preventing filter pore clogging, extending filter element life, and avoiding frequent filter element replacements.
