Description

Technical Field

[0001] The utility model relates to the technical field of hindered settlers, in particular to a water supply device for a hindered settler and the hindered settler. Background Art

[0002] The hindered settler is an important industrial device primarily used for separating solid particles in suspensions. Its operating principle is based on the fact that the settling velocity of particles is affected by the fluid velocity and the relative velocity between particles. When the fluid contains a large number of particles, the movement of adjacent particles alters the flow field surrounding a single particle, interfering with the settling of the particles and reducing their settling velocity. This gravity-induced settling is known as hindered settling. By rationally designing the flow field, the hindered settler effectively controls the relative velocity between particles, thereby improving the separation efficiency. Specifically, the hindered settler typically consists of a vertical cylindrical or conical settling chamber. Fluid enters from the top, and particles settle downward under the influence of gravity and fluid drag. A stirring device or turbine is installed in the settling chamber to generate countercurrent flow fields, effectively controlling the relative velocity between particles. The water supply system for the hindered settler is a critical component of the device, and its design and performance directly impact the separation efficiency and operational stability of the settler.

[0003] After searching, announcement number CN201880405U discloses a high-pressure energy-saving water supply device for an obstructed settler and an obstructed settler, the high-pressure energy-saving water supply device for an obstructed settler includes a cylinder, a water supply pipe is provided on the cylinder, a water tank bottom plate and a flow stabilizer are provided in the cylinder, the flow stabilizer is inclined and forms an angle with the water tank bottom plate, and at least one nozzle is evenly distributed on the flow stabilizer; the obstructed settler includes a feeding part, an overflow trough and a discharge part, and also includes the water supply device described above, the feeding part is arranged on the upper part of the cylinder through a bracket, the overflow trough is arranged below the feeding part, and its bottom is inclined, and the discharge part is arranged at the bottom of the cylinder. In fact, The new flow stabilizer is set at an angle to enhance the pressure resistance and can achieve non-deformation during high-pressure water supply; when the water supply pressure of the water supply device is high, the liquid flow in the cylinder remains stable, forming an effective turbulent area; and it is conducive to the sedimentation and concentration of coarse particles, and does not produce local siltation; and the defect is that: when the device turbulently flows the water, it generates turbulence to the water flow through the nozzle, resulting in poor turbulence effect, and cannot effectively enhance the diffusion and collision of solid particles in the fluid, resulting in poor separation effect. Therefore, it is particularly important to improve the existing water supply device and design a new water supply device and hindered settler for the obstructed settler to solve the above technical defects and improve the practicality of the overall water supply device. Utility Model Content

[0004] The purpose of the present utility model is to provide a water supply device for an obstructed settler and an obstructed settler, through a plurality of groups of oblique laminar flow adjustment cone grooves, since the diameter reduction flow area of the oblique laminar flow adjustment cone grooves is gradually reduced, the flow velocity of the fluid in the oblique laminar flow adjustment cone groove flow channel will be increased, and when the position of the fixed cylinder is reached, the fluid realizes the conversion from laminar flow state to turbulent flow state, and by setting a turbulence adjustment plate, the pipeline flow velocity can be made more uniform and stable, and when the fluid in the turbulent state is introduced into the interior of the fixed cylinder, the fluid can be accelerated and guided by the spiral block, and the spiral line rotates and disturbs and enters above the flow stabilizing plate to promote the turbulent effect, and when the fluid is introduced into the interior of the fixed cylinder and contacts with the spiral block, the direction of the fluid is changed, so that the fluid crosses, meets and collides, and further disturbance of the fluid is increased, thereby making the turbulent effect better, so as to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0020] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Example:

[0022] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0023] A water supply device for a blocked settler includes a connecting tube body 1, a water inlet pipe 2 is provided on the outside of the connecting tube body 1, a water tank bottom plate 3 is provided inside the connecting tube body 1, a flow stabilizing plate 4 is provided above the water tank bottom plate 3 and inside the connecting tube body 1, and a plurality of turbulent flow components 5 are provided inside the flow stabilizing plate 4;

[0024] The turbulent flow component 5 is used to perform turbulent flow treatment on the water flow introduced into the connecting tube body 1, and the turbulent flow component 5 is composed of a connecting shell 6, a fixed tube 7, a fixed rod 8 and a spiral block 9. The connecting shell 6 is located on the outside of the flow stabilizer 4, the fixed tube 7 is located on the outside of the connecting shell 6, the fixed rod 8 is located inside the fixed tube 7, and the spiral block 9 is located on the outside of the fixed rod 8.

[0025] Furthermore, a plurality of groups of oblique laminar flow adjustment cone grooves 10 are provided inside the connecting shell 6, and the plurality of groups of oblique laminar flow adjustment cone grooves 10 are distributed at equal intervals inside the connecting shell 6. When the water flow is introduced into the interior of the connecting cylinder body 1 through the water inlet pipe 2, after water of a certain flow rate and appropriate pressure is fed, the water flow is introduced into the interior of the connecting shell 6, and passes through the plurality of oblique laminar flow adjustment cone grooves 10 inside thereof. As the diameter reduction flow area of the oblique laminar flow adjustment cone groove 10 gradually decreases, the flow velocity of the fluid in the flow channel of the oblique laminar flow adjustment cone groove 10 will increase, and when the fluid reaches the position of the fixed cylinder 7, the fluid realizes the conversion from laminar flow state to turbulent flow state.

[0026] Among them, the external structure size of the spiral block 9 is designed to correspond to the internal structure size of the fixed cylinder 7, and the spiral block 9 is designed to have a spiral structure on the outside of the fixed rod 8. When the fluid in a turbulent state is introduced into the interior of the fixed cylinder 7, the spiral block 9 can accelerate and guide the fluid, and the spiral line rotates and disturbs it, and enters above the flow stabilizer 4, thereby promoting the turbulent effect.

[0027] Secondly, multiple groups of protrusions 11 are provided on the outside of the spiral block 9. The multiple groups of protrusions 11 are distributed at equal intervals on the outside of the spiral block 9, and grooves are formed between the multiple groups of protrusions 11. When the fluid is introduced into the interior of the fixed cylinder 7 and contacts the spiral block 9, the direction of the fluid is changed, causing the fluid to cross, meet and collide, thereby increasing further disturbance of the fluid, thereby making the turbulent flow effect better.

[0028] Furthermore, a turbulence adjustment plate 12 is provided inside the fixed cylinder 7 and near one end of the connecting shell 6. The turbulence adjustment plate 12 has multiple groups of through grooves therein. By providing the turbulence adjustment plate 12, the flow velocity in the pipeline can be made more uniform and stable.

[0029] The present utility model also provides an obstructed settler, including a water supply device for an obstructed settler provided in any of the above embodiments. Since it has all the technical features of the water supply device for an obstructed settler provided in any of the above embodiments, it has the same technical effect as the above water supply device for an obstructed settler, including a feeding portion 13, an overflow trough 14 and a discharge portion 15. The feeding portion 13 is installed on the end of the connecting tube body 1 away from the water inlet pipe 2 through a bracket. The overflow trough 14 is opened below the feeding portion 13 and is located inside the connecting tube body 1. The discharge portion 15 is located at the end of the connecting tube body 1 close to the water inlet pipe 2. The bottom of the overflow trough 14 is designed as an inclined structure, and an overflow port 16 is opened on the outside of the overflow trough 14.

[0030] In this embodiment, the implementation scenario is specifically as follows: when the water flow is introduced into the interior of the connecting tube body 1 through the water inlet pipe 2, after water with a certain flow rate and appropriate pressure is fed, the water flow is introduced into the interior of the connecting shell 6, and passes through the multiple groups of oblique laminar flow adjustment cone grooves 10 inside it. Since the diameter reduction flow area of the oblique laminar flow adjustment cone grooves 10 is gradually reduced, the flow velocity of the fluid in the flow channel of the oblique laminar flow adjustment cone grooves 10 will increase. When the fluid reaches the position of the fixed tube 7, the fluid realizes the conversion from laminar flow state to turbulent state. By setting the turbulence adjustment plate 12, the pipeline flow velocity can be made more uniform and stable. When the fluid in the turbulent state is introduced into the interior of the fixed tube 7, the spiral block 9 can accelerate and guide the fluid, and the spiral line rotates and disturbs it, and enters above the flow stabilizing plate 4 to promote the turbulent effect. When the fluid is introduced into the interior of the fixed tube 7 and the spiral block 9 When in contact, the direction of the fluid is changed, so that the fluid crosses, meets and collides, which increases the further disturbance of the fluid, thereby making the turbulence effect better. When the specific gravity in water is the same, large particles settle faster than small particles; and when the particle size is the same but the specific gravity is different, particles with a larger specific gravity settle faster than particles with a smaller specific gravity. Materials of a certain particle size remain suspended under the action of the rising water flow. This area is called the turbulent zone. Larger particles or particles with a larger specific gravity in the selected materials will pass through the turbulent zone and settle to the bottom and be discharged from the discharge part 15; smaller particles or particles with a lighter specific gravity will not pass through the turbulent zone, but float to the upper part, flow out from the overflow weir and gather in the overflow trough 14, and flow out from the overflow port 16, thereby achieving the purpose of classification. Compared with the existing water supply device, the utility model can improve the overall practicality of the water supply device through design.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
