Description

Technical Field

[0001] This utility model relates to the field of solid-liquid separation equipment, and more specifically, to a cyclone solid-liquid separator. Background Technology

[0002] Currently, most particleboard factories treat their exhaust gases using wet spraying and wet electrostatic precipitators. This process requires a large flow of circulating water for spraying, transferring fiber dust from the exhaust gas into the circulating water. It is essential to promptly separate and remove particulate matter from the circulating water to prevent spray head clogging and to ensure the circulating water has a continuous fiber dust removal capacity.

[0003] Traditional treatment methods include using self-cleaning filters or traditional sedimentation tanks. Self-cleaning filters effectively protect the spray heads from clogging, but they are prone to clogging themselves, making cleaning and maintenance during production very troublesome. Traditional sedimentation tanks, on the other hand, struggle to achieve good separation results with large flow rates of circulating water.

[0004] Existing hydrocyclones on the market are improvements on cyclone dust collectors, mainly used to separate substances with a higher specific gravity in water, or for separating small volumes of sludge in wastewater treatment. Therefore, existing hydrocyclones have a large height-to-diameter ratio and relatively small size, which cannot meet the requirements of large-flow circulating water treatment for exhaust gas in wood-based panel factories.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] like Figures 1-3 As shown, this utility model provides a cyclone solid-liquid separator, including a cylindrical body 1, a conical structure 2 connected to the cylindrical body 1, and a flow guiding structure disposed inside the cylindrical body 1. The cylindrical body 1 is provided with an inlet 5 and an outlet 6, and the bottom of the conical structure 2 is provided with a drain outlet 14. The cylindrical body 1 provides a swirling space for a large flow of water. Wastewater enters the cylindrical body 1 tangentially from the inlet 5, and centrifugal force causes suspended solids to move towards the wall of the separator. The conical structure 2 is used to collect settled sludge, and the drain outlet 14 discharges the sludge.

[0022] The flow guiding structure includes a flow guiding cylinder 3 and a flow guiding cone 4 connected to the flow guiding cylinder 3. The flow guiding cylinder 3 is connected to the top of the cylindrical body 1. Water flows tangentially into the area between the cylindrical body 1 and the flow guiding cylinder 3 through the inlet 5. A water outlet pipe 7 connected to the outlet 6 is provided inside the cylindrical body 1. The water outlet pipe 7 extends from the outlet 6 into the flow guiding structure. The water outlet weir 8 connected to the water outlet pipe 7 is located inside the flow guiding cylinder 3.

[0023] In the above scheme, after the water flows tangentially into the container, it forms an outer vortex flow, which moves downward along the inner wall of the cylindrical body 1 to below the guide cone 4. Due to the effect of the water head, it then forms an inner vortex flow in a rotating manner, moving towards the inside and above the guide cone 4, and flowing upward through the inside of the guide tube 3. This creates two vortex flows, one inner and one outer, located on the inner and outer sides of the guide cone 4, respectively. The two vortex flows converge below the guide cone 4. Because the suspended solids in the circulating water have a higher specific gravity, under the action of centrifugal force, the suspended solids are thrown towards the inner wall of the cylindrical body 1 and fall into the cone structure 2 along the inner wall under the action of centrifugal force and gravity. The supernatant flows through the outlet weir 8 to the outlet pipe 7 for discharge. By setting the guide tube 3 and the guide cone 4 to cooperate to form inner and outer double vortex flows, the water flow path is extended, and the centrifugal separation effect is enhanced.

[0024] Among them, the included angle of the generatrix of the guide cone 4 determines the inclination of the cone surface, which affects the speed at which suspended matter slides down the cone wall and the distribution of centrifugal force. In this scheme, the included angle between the two generatrixes of the guide cone 4 is 60-90°, which avoids sludge retention due to too small an included angle, and also prevents the centrifugal effect from being weakened by too large an included angle, thereby improving the separation efficiency.

[0025] The guide cone 4 is circumferentially provided with several connecting rods 9, which are fixedly connected to the cylindrical body 1. The outlet pipe 7 is provided with several connecting rods 16, which are fixedly connected to the guide cylinder 3. The connecting rods 9 and 16 rigidly connect the guide cone 4, the guide cylinder 3, and the cylindrical body 1, respectively, ensuring that the guide structure remains stable under the impact of high-flow water, avoiding a decrease in separation effect due to vibration, and improving equipment reliability.

[0026] The height ratio of the cylindrical body 1 to the conical structure 2 is 1:1. The equal height design balances the ratio of the rotational separation space of the cylindrical body 1 to the settling space of the conical structure 2, thereby increasing the sludge storage volume and reducing the sludge discharge frequency while ensuring the centrifugal separation effect.

[0027] The guide tube 3 has several vent holes 10 arranged circumferentially, and the top cover of the cylindrical body 1 has a vent 11. The vent holes 10 and the vent 11 connect the airflow inside and outside the equipment, balance the air pressure inside and outside the guide tube 3 and the air pressure inside the cylindrical body 1, prevent the air pressure difference caused by the rotation of the water flow from affecting the stability of the water flow, avoid the decrease in separation efficiency caused by air resistance, and ensure the safe operation of the equipment.

[0028] The top cover of the cylindrical body 1 is also provided with a water inlet 12 and an inspection port 13. The water inlet 12 is used to replenish circulating water or adjust the water level; the multiple inspection ports 13 facilitate staff to observe the internal operation or perform maintenance.

[0029] The drain outlet 14 is also connected to a backwash port 15. The backwash port 15 is connected to a high-pressure water flow or compressed air to flush away the sludge accumulated at the bottom of the cone structure 2. This prevents the sludge from caking and clogging the drain outlet 14, ensuring smooth sludge discharge and maintaining long-term stable operation of the equipment.

[0030] The cyclone solid-liquid separator in this design has no internal mechanical moving parts, requiring almost no manual maintenance during operation, thus avoiding the problems of easy clogging and troublesome maintenance of filtration equipment. Utilizing the principle of cyclone centrifugation, it forms an inner and outer double vortex flow through a flow-guiding structure, effectively separating suspended solids with a higher specific gravity from large-flow circulating water, solving the problem of poor separation performance of traditional sedimentation tanks for large-flow circulating water.

[0031] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
