Description

Technical Field

[0001] The present invention relates to the field of mud-water separation, and particularly to a rapid mud-water separation device. Background Art

[0002] During tunnel construction period, wastewater and the flushing drainage water from concrete mixing plants mainly contain suspended solids, stone chips, stone powder, mud, oil substances, and various additives and TNT residues in concrete, with a high mud-water concentration ratio. At present, the equipment for coagulation sedimentation treatment of wastewater during engineering construction is generally a coagulation sedimentation tank, which has many forms. The common ones are horizontal flow sedimentation tanks, vertical flow sedimentation tanks, and radial flow sedimentation tanks. Its structure generally has a stirring reaction device installed on the top of the tank, and the coagulant is fully mixed through mechanical stirring to play a flocculation role. However, the sedimentation after coagulation needs to be in a static state to achieve the best effect. In recent years, in order to improve the sedimentation efficiency and control the suspended solid concentration in the effluent, a batch of new sedimentation equipment, such as swirl coagulation reaction tanks, micro-vortex reaction sedimentation tanks, inclined tube sedimentation tanks, etc., have emerged and are widely used in actual engineering applications. However, limited by their structural design defects, they have a large floor area, high operating costs, and inconvenient maintenance, and cannot achieve a satisfactory treatment effect and have poor sedimentation effect. Summary of the Invention

[0003] The object of the present invention is to provide a rapid mud-water separation device.

[0004] The innovation point of the present invention is that the water and the reagent are evenly mixed in the present invention, and the mud-water separation speed is fast.

[0005] To achieve the above-mentioned invention object, the technical solution of the present invention is: a rapid mud-water separation device, including a cylinder body. An outlet is provided on the upper side wall of the cylinder body. A water inlet pipe communicating with the inside of the cylinder body is provided on the side wall of the cylinder body. A chemical dosing port is provided on the water inlet pipe. The end of the water inlet pipe located inside the cylinder body is bent downward, and a micro-vortex reaction cylinder is fixedly provided at the end. The micro-vortex reaction cylinder is a cylindrical structure. A through hole inserted into the water inlet pipe is provided at the top of the micro-vortex reaction cylinder. The bottom of the micro-vortex reaction cylinder is closed. A plurality of nozzles protruding outward are provided on the side wall of the micro-vortex reaction cylinder. The nozzles are located on the same horizontal plane and the nozzles rotate simultaneously in the clockwise direction or simultaneously in the counterclockwise direction. The height of the end of the water inlet pipe inserted into the micro-vortex reaction cylinder is lower than the height of the nozzles. The micro-vortex reaction cylinder is located inside a swirl reaction cover. The top of the swirl reaction cover is closed and the bottom is open.

[0006] Further, the cylinder body is cylindrical, and the micro-vortex reaction cylinder is located on the central axis of the cylinder body.

[0007] Further, the nozzles are arranged at equal intervals along the circumferential direction of the micro-vortex reaction cylinder, and the number of nozzles is 6 - 8.

[0008] Furthermore, the direction of the nozzle is the tangential direction of the circumference of the micro-vortex reaction cylinder and slopes downward, with good swirling effect.

[0009] Furthermore, the distance from the end of the water inlet pipe inserted into the micro-vortex reaction cylinder to the bottom of the micro-vortex reaction cylinder is 5 - 10 cm, which can ensure the water output while meeting the requirement of the water in the water inlet pipe having a reflection force.

[0010] Furthermore, the swirling reaction cover is in the shape of a frustum of a cone, with good swirling effect.

[0011] Furthermore, an inclined tube sedimentation area is provided inside the cylinder body, which is located above the water inlet pipe and below the water outlet. The inclined tube packing area is divided into a lower inclined tube packing area, a stable flow area, and an upper inclined tube packing area from bottom to top, and the inclination directions of the lower inclined tube packing area and the upper inclined tube packing area are opposite.

[0012] Furthermore, the bottom of the cylinder body is a inverted frustum-shaped sludge hopper. On the one hand, it is conducive to sludge discharge. On the other hand, when the sludge rotates downward rapidly along the inner wall of the swirling reaction cover, it can collide with the suspended particles in the upper part of the inverted frustum-shaped sludge hopper, forming larger sludge particles, which is conducive to the sedimentation of sludge particles.

[0013] Furthermore, a sludge suction pipe is provided at the inverted frustum-shaped sludge hopper. The sludge suction port of the sludge suction pipe is located at the inverted frustum-shaped sludge hopper, and the sludge discharge port of the sludge suction pipe is located outside the cylinder body, and the height of the discharge port is lower than that of the suction port. A valve is provided on the sludge suction pipe outside the cylinder body, and the suction port is in the shape of a bell mouth. Sludge can be discharged through the siphon principle.

[0014] Furthermore, a water outlet weir is provided inside the cylinder body at the water outlet, for uniformly collecting clear water.

[0015] The beneficial effects of the present invention are as follows: 1. In the present invention, the combination of the micro-vortex reaction cylinder and the swirling reaction cover is adopted, and through its own hydraulic conditions, the coagulant and the wastewater generate a vortex reaction, and the large sludge particles generated by the vortex reaction are rapidly sedimented and separated under the action of the swirling centrifugal force, forming sludge precipitation.

[0016] 2. In the present invention, the water and the reagent are evenly mixed, and the separation speed of the mud and water is fast.

[0017] 3. In the present invention, the advantages of vortex reaction, swirling sedimentation, contact collision and inclined tube sedimentation are fully utilized, maximizing the sedimentation efficiency, reducing the energy consumption, and the high-efficiency vortex flow inclined tube sedimentation equipment has the advantages of strong impact resistance, large operation flexibility, small floor area and convenient maintenance.

[0021] Embodiment 1: As Figure 1 、 2 、Figure 3 shows, a rapid mud-water separation device, including a cylinder body 1, the cylinder body 1 is cylindrical, a water outlet 2 is provided on the upper side wall of the cylinder body 1, and a weir 13 is provided in the cylinder body 1 at the water outlet 2. A water inlet pipe 3 leading into the cylinder body 1 is provided on the side wall of the cylinder body 1, a chemical dosing port 4 is provided on the water inlet pipe 3, the end of the water inlet pipe 3 located inside the cylinder body 1 is bent downward and a micro-vortex reaction cylinder 5 is fixedly provided at the end, the micro-vortex reaction cylinder 5 is of a cylindrical structure, the micro-vortex reaction cylinder 5 is located on the central axis of the cylinder body 1, a through hole 6 inserted into the water inlet pipe 3 is provided at the top of the micro-vortex reaction cylinder 5, the bottom of the micro-vortex reaction cylinder 5 is closed, several nozzles 7 protruding outward are provided on the side wall of the micro-vortex reaction cylinder 5, the nozzles 7 are located on the same horizontal plane and the nozzles 7 rotate in the clockwise direction or the counterclockwise direction at the same time, preferably the nozzles 7 are arranged at equal intervals along the circumferential direction of the micro-vortex reaction cylinder 5, the number of the nozzles 7 is 6 - 8, the direction of the nozzles 7 is the tangent direction of the circumference of the micro-vortex reaction cylinder 5 and inclines downward, the height of the end of the water inlet pipe 3 inserted into the micro-vortex reaction cylinder 5 is lower than the height of the nozzles 7, and the distance between the end of the water inlet pipe 3 inserted into the micro-vortex reaction cylinder 5 and the bottom of the micro-vortex reaction cylinder 5 is 5 - 10 cm. The micro-vortex reaction cylinder 5 is located inside a swirl reaction cover 8, the top of the swirl reaction cover 8 is closed and the bottom is open, and the swirl reaction cover 8 is of a frustum-shaped structure. An inclined tube sedimentation area 9 is provided in the cylinder body 1, the inclined tube sedimentation area 9 is located above the water inlet pipe 3 and below the water outlet 2, the inclined tube packing area 9 is respectively a lower inclined tube packing area 9.1, a steady flow area 9.2, and an upper inclined tube packing area 9.3 from bottom to top, and the inclination directions of the lower inclined tube packing area 9.1 and the upper inclined tube packing area 9.3 are opposite. The bottom of the cylinder body 1 is an inverted frustum-shaped sludge hopper 10. A sludge suction pipe 11 is provided at the inverted frustum-shaped sludge hopper 10, the sludge suction port 11.1 of the sludge suction pipe 11 is located at the inverted frustum-shaped sludge hopper 10, the sludge outlet 11.2 of the sludge suction pipe 11 is located outside the cylinder body 1, and the height of the sludge outlet 11.2 is lower than that of the sludge suction port 11.1. A valve 12 is provided on the sludge suction pipe 11 outside the cylinder body 1, and the sludge suction port 11.1 is a flared mouth.

[0022] During operation, the coagulant and wastewater are mixed to form a mixed liquid which then enters the micro-vortex reaction cylinder 5. When the mixed liquid reaches the bottom of the micro-vortex reaction cylinder 5, it is reflected upward to form a vortex reaction, so that the reagent and wastewater in the mixed liquid are evenly mixed, and then sprayed out through the nozzle 7. Since the nozzle 7 is located on the same horizontal plane and the nozzle 7 rotates clockwise or counterclockwise at the same time, the mixed liquid is swirled out from the nozzle 7, and swirling sedimentation occurs in the swirling reaction cover 8. Larger particles are thrown to the inner wall of the swirling reaction cover 8 under the action of centrifugal force and are spun along the swirling reaction cover 8. The inner wall of the cyclone reaction hood 8 rotates and moves downward rapidly, and is deposited in the inverted truncated cone sludge collecting bucket 10 at the bottom. When the sludge rotates and moves downward rapidly along the inner wall of the cyclone reaction hood 8, it can collide with the suspended particles on the upper part of the inverted truncated cone sludge collecting bucket 10 to form larger particles; after the smaller particles of suspended matter swirl downward to a certain extent, they will swirl upward with the water flow to form a secondary vortex reaction, gradually accumulate to form colloidal substances, and are captured by the upper double-layer inclined tube filler sludge layer to form large sludge particles that slide down, form sedimentation, and accumulate in the inverted truncated cone sludge collecting bucket 10 at the bottom. The clean water passing through the inclined tube filling area 9 moves to the top in an upward flow state, is evenly collected by the water outlet weir 13, and is discharged at the water outlet 2; the lower inclined tube filling area and the upper inclined tube filling area are arranged at the inclined tube filling area 9 with opposite inclinations, which is more conducive to sludge sedimentation. The steady flow area 9.2 is arranged in the middle to avoid the sludge particles from changing direction rapidly and causing crushing, and on the other hand, it can make part of the sludge fall in the steady flow area 9.2, reducing the load of the upper inclined tube filling area 9.3. The mud discharge tank opens the valve 12. Since the mud outlet 11.2 is lower than the mud suction port 11.1, as long as a little suction force is applied at the mud outlet, the mud can be discharged through the siphon principle.
