Description

Technical Field

[0001] The utility model relates to the technical field of grid residue treatment, in particular to a grid residue collection and transfer device for wastewater treatment. Background Technique

[0002] A grid machine is a slag collection and discharge device for sewage sludge treatment. When it works, the grid rotates within the frame, intercepting suspended solids and impurities in the sewage and continuously separating the suspended solids in the water. When the equipment is operating, the rake teeth carry the grid residue formed by the slag intercepted on the grid surface from bottom to top to the slag discharge port. When the rake teeth turn downward from top to bottom, the grid residue falls off by gravity and drops into the slag conveying bin from the discharge port.

[0003] Under the existing technology, multiple grid machines are equipped in a large sewage tank for grid residue treatment. Each grid machine needs to be equipped with a corresponding conveying device to convey the unloaded grid residue, resulting in an increase in the cost of auxiliary conveying equipment and low working efficiency. Therefore, a grid residue collection tooling that can handle the grid residue unloaded by multiple grid machines is needed to achieve an integrated grid residue collection effect and improve the slag collection efficiency.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0027] Please refer to Figures 1-4, the utility model provides a technical solution: a grid residue collection and transfer device for wastewater treatment, including a sewage tank 1, a rotary grille machine 2 and a residue box 3. Multiple groups of rotary grille machines 2 are installed in the sewage tank 1. The residue box 3 is provided with multiple groups of residue troughs 301 corresponding to the slag discharge ports of the rotary grille machines 2. The residue troughs 301 penetrate the residue box 3. Driving motors 4 and screws 5 are installed on both sides of the residue box 3. The output shaft of the driving motor 4 is in transmission connection with the screw 5. First chutes 302 and second chutes 303 are respectively opened on both sides of the residue trough 301. First pressing plates 7 and second pressing plates 8 are symmetrically arranged in the residue trough 301. First sliding rods 6 threadedly connected to the screw 5 are slidably connected in both the first chute 302 and the second chute 303. The first sliding rod 6 on the side of the first chute 302 is fixedly connected to the first pressing plate 7, and the first sliding rod 6 on the side of the second chute 303 is fixedly connected to the second pressing plate 8. A bottom plate 10 is rotatably connected to the bottom side of the residue box 3. The rotation angle of the bottom plate 10 is greater than or equal to 90°. A conveyor belt 11 is arranged on the bottom side of the bottom plate 10. One end of the conveyor belt 11 extends to one side of the sewage tank 1. The residue trough 301 is completely located above the conveyor belt 11. When the rotary grille machine 2 is working, the residue of each rotary grille machine 2 is discharged from the discharge port into the corresponding residue trough 301. Then, two groups of driving motors 4 are started to drive the screw 5 to rotate. According to the principle of screw drive, the two groups of first sliding rods 6 on the left drive the two groups of first pressing plates 7 in the two residue troughs 301 to move synchronously to the right, and the two groups of first sliding rods 6 on the right drive the two groups of second pressing plates 8 in the two residue troughs 301 to move synchronously to the left, that is, the two groups of pressing plates in the two residue troughs 301 move synchronously towards each other to squeeze the residue thereinto into a residue cake, simultaneously processing the residue unloaded by multiple grille machines and improving the working efficiency.

[0028] Specifically, as Figure 2 and Figure 4 shown, connecting rods 16 are fixedly connected to the bottom sides of both sides of the residue box 3. A rotating shaft is used to rotatably connect the two groups of connecting rods 16 to one side of the bottom plate 10. Support plates 9 are fixedly connected to both sides of the residue box 3. An electric push rod 15 is fixedly installed on the support plate 9. The push rod end of the electric push rod 15 is fixedly connected to a second sliding rod 14. Third chutes 1002 slidably matched with the second sliding rod 14 are opened on both sides of the bottom plate 10. After the residue is squeezed into a residue cake, the electric push rod 15 is started to drive the second sliding rod 14 to descend. The second sliding rod 14 also slides in the third chute 1002 at the same time, driving the bottom plate 10 to rotate around the rotating shaft, opening the residue trough 301, and the residue cake slides onto the conveyor belt 11 along the bottom plate 10, and the residue cake is sent out through the conveyor belt 11, realizing the integrated collection and transfer of the residue, eliminating the need to equip multiple conveying devices, reducing the cost of auxiliary conveying devices, and improving the working efficiency.

[0029] Specifically, as Figure 2As shown in the figure, a water discharge groove 1001 is formed on the bottom plate 10. A mesh plate 12 is embedded at the top of the water discharge groove 1001. The mesh plate 12 is in contact with the bottoms of the first slag pressing plate 7 and the second slag pressing plate 8. The middle part of the bottom side of the water discharge groove 1001 is fixedly communicated with a water discharge hose 13. When the grid residue is discharged and during the process of being extruded into a slag cake, the water flows into the water discharge groove 1001 through the mesh plate 12 and finally is discharged along the water discharge hose 13.

[0030] Working principle: When in use, when the rotary grille machine 2 is working, the grid residue of each rotary grille machine 2 is discharged from the discharge port into the corresponding grid residue tank 301. Then, two groups of driving motors 4 are started to drive the screw 5 to rotate. According to the principle of screw drive, the two groups of first sliding rods 6 on the left side are driven to drive the two groups of first slag pressing plates 7 in the two grid residue tanks 301 to move synchronously to the right, and the two groups of first sliding rods 6 on the right side drive the two groups of second slag pressing plates 8 in the two grid residue tanks 301 to move synchronously to the left, that is, the two groups of slag pressing plates in the two grid residue tanks 301 move synchronously towards each other to extrude the grid residue therebetween into a slag cake. After that, the electric push rod 15 is started to drive the second sliding rod 14 to descend. The second sliding rod 14 also slides in the third sliding groove 1002 at the same time, driving the bottom plate 10 to rotate around the rotating shaft, opening the grid residue tank 301, and the slag cake slides down along the bottom plate 10 onto the conveyor belt 11. The slag cake is sent out through the conveyor belt 11. At the same time, the grid residue unloaded from multiple grille machines is processed, realizing the integrated collection and transfer of grid residue, eliminating the need to be equipped with multiple conveying devices, reducing the cost of auxiliary conveying devices, and improving work efficiency.
