Description

Technical Field

[0001] The utility model relates to a sludge storage device. Background Art

[0002] At present, during the process of sludge disposal, a storage bin is needed to collect and store sludge, and then the sludge in the storage bin is transported to subsequent processing equipment for disposal. An improved sludge storage device disclosed in a Chinese patent with the publication number CN208775518U can be used to collect and store sludge. Due to the poor fluidity, large viscosity and strong adhesiveness of sludge, when the sludge is discharged from the storage bin, phenomena such as arching and bridging are likely to occur. The arched and bridged sludge cannot fall and thus cannot be discharged, resulting in unsmooth sludge discharge. To solve the above problems, some enterprises use a vibrating device to vibrate the storage bin manually, so that the arched and bridged sludge vibrates and falls. However, this will increase the workload of on-site workers, as well as their labor intensity and work risks. Content of the Utility Model

[0032] In order to make the content of the present utility model be more clearly understood, the following further details the present utility model according to specific embodiments and in conjunction with the drawings.

[0033] As Figures 1 to 3 shown, a sludge storage device includes a silo 1, a spiral conveyor shaft 2, an arch-breaking stirring shaft 3, a transmission mechanism 4 and a driving mechanism 5;

[0034] The silo 1 is used for storing sludge, and at least one discharge port is provided at the bottom of the silo 1;

[0035] The spiral conveyor shaft 2 is rotatably connected to the bottom of the silo 1;

[0036] The arch-breaking stirring shaft 3 is rotatably connected in the silo 1 and is located above the spiral conveyor shaft 2;

[0037] The spiral conveyor shaft 2 is drivingly connected to the arch-breaking stirring shaft 3 through the transmission mechanism 4;

[0038] The driving mechanism 5 is connected to the spiral conveyor shaft 2 and is used to drive the spiral conveyor shaft 2 to rotate to convey the sludge in the silo 1 to the discharge port for discharging. Moreover, the spiral conveyor shaft 2 drives the arch-breaking stirring shaft 3 to rotate through the transmission mechanism 4, so that the arch-breaking stirring shaft 3 stirs and breaks the arching and bridging sludge in the silo 1 during rotation, thereby causing the sludge to fall downward, increasing the fluidity of the sludge. The fallen sludge is then conveyed to the discharge port by the spiral conveyor shaft 2 for discharging, enabling the sludge to be discharged smoothly. Through the combined action of the spiral conveyor shaft 2 and the arch-breaking stirring shaft 3, automatic arch breaking can be achieved during the sludge discharging process, and it can also reduce the workload and labor intensity of on-site workers and improve the safety of on-site work.

[0039] As Figures 1 to 3 shown, two spiral conveyor shafts 2 can be arranged in parallel, and the two spiral conveyor shafts 2 are respectively rotatably connected to the bottom of the silo 1;

[0040] The transmission mechanism 4 can include a first gear 6, a second gear 7, and a third gear 8;

[0041] The first gear 6 is connected to one of the spiral conveyor shafts 2;

[0042] The second gear 7 is connected to the other spiral conveyor shaft 2;

[0043] The third gear 8 is connected to the arch-breaking stirring shaft 3;

[0044] The first gear 6 meshes with the second gear 7, and the first gear 6 also meshes with the third gear 8. The driving mechanism 5 is connected to any one of the spiral conveyor shafts 2 and is used to drive the spiral conveyor shaft 2 to rotate; specifically, when the driving mechanism 5 drives the spiral conveyor shaft 2 connected to it to rotate, it can drive the arch-breaking stirring shaft 3 and the other spiral conveyor shaft 2 to rotate together.

[0045] As Figures 1 to 3As shown, the drive mechanism 5 may include a reduction motor, which is connected to any one of the screw conveyor shafts 2. Specifically, the reduction motor can drive the screw conveyor shaft 2 connected thereto to rotate, and then drive the other screw conveyor shaft 2 to rotate through the meshing of the first gear 6 and the second gear 7, and at the same time drive the arch-breaking stirring shaft 3 to rotate through the meshing of the first gear 6 and the third gear 8. Therefore, one reduction motor can drive two screw conveyor shafts 2 and one arch-breaking stirring shaft 3 to rotate, saving the number of reduction motors used and reducing the production cost of the equipment. In this embodiment, the reduction motor is connected to the screw conveyor shaft 2 equipped with the first gear 6 through a coupling.

[0046] As Figure 1 shown, there may be two discharge ports, namely a first discharge port 9 and a second discharge port 10. Specifically, setting two discharge ports can improve the sludge discharge speed.

[0047] As Figure 1 、 2 shown, a first spiral blade 11, a second spiral blade 12, and a third spiral blade 13 are arranged in sequence on one of the screw conveyor shafts 2. The first discharge port 9 is located between the first spiral blade 11 and the second spiral blade 12, and the second discharge port 10 is located between the second spiral blade 12 and the third spiral blade 13.

[0048] A fourth spiral blade 14, a fifth spiral blade 15, and a sixth spiral blade 16 are arranged in sequence on the other screw conveyor shaft 2. The first discharge port 9 is also located between the fourth spiral blade 14 and the fifth spiral blade 15, and the second discharge port 10 is also located between the fifth spiral blade 15 and the sixth spiral blade 16. Specifically, when the two screw conveyor shafts 2 rotate, they can transport the sludge in the silo 1 to the first discharge port 9 and the second discharge port 10 for discharge.

[0049] In this embodiment, the first spiral blade 11 meshes with the fourth spiral blade 14, the second spiral blade 12 meshes with the fifth spiral blade 15, and the third spiral blade 13 meshes with the sixth spiral blade 16.

[0050] As Figure 1 、 2 shown, the arch-breaking stirring shaft 3 may include a shaft body and a plurality of arch-breaking paddle blades 17. The shaft body is rotatably connected to the silo 1, and the arch-breaking paddle blades 17 are connected to the shaft body.

[0051] As Figure 3 shown, the silo 1 may include an upper shell 18, a lower shell 19, and a bottom shell 20.

[0052] The lower end of the upper housing 18 is connected to the upper end of the lower housing 19;

[0053] The lower end of the lower housing 19 is connected to the bottom shell 20;

[0054] The screw conveyor shaft 2 is rotatably arranged in the bottom shell 20.

[0055] As Figure 3 shown, the lower housing 19 can be a conical structure with a larger upper part and a smaller lower part;

[0056] The bottom of the bottom shell 20 can be an arc structure; specifically, compared with the traditional conical bottom shell 20, the arc-shaped bottom shell 20 in this embodiment can save more space and avoid caking.

[0057] As Figure 1 shown, a plurality of bearing seats 21 can be connected to the silo 1, and the screw conveyor shaft 2 and the arch-breaking stirring shaft 3 are respectively rotatably connected to the corresponding bearing seats 21.

[0058] In summary, when the driving mechanism 5 drives the screw conveyor shaft 2 to rotate, the sludge in the silo 1 can be conveyed to the discharge port for discharging. And the screw conveyor shaft 2 drives the arch-breaking stirring shaft 3 to rotate through the transmission mechanism 4, so that the arch-breaking stirring shaft 3 stirs and breaks the caked and bridged sludge in the silo 1 during rotation, thereby causing the sludge to fall downward, increasing the fluidity of the sludge. The fallen sludge is then conveyed to the discharge port by the screw conveyor shaft 2 for discharging, enabling the sludge to be discharged smoothly. Through the combined action of the screw conveyor shaft 2 and the arch-breaking stirring shaft 3, automatic arch-breaking can be achieved during the sludge discharging process, reducing the workload and labor intensity of on-site workers and improving the safety of on-site work.
