Description

Technical Field

[0001] The utility model relates to the technical field of cement storage equipment, in particular to a cement overflow device for a cement silo. Background Art

[0002] The sludge conveying silo, also known as the cement silo, is generally used for the bulk cement storage in a concrete mixing plant, and is suitable for storing various bulk building materials such as cement and fly ash. A level system is installed on the silo body to display the position and quantity of the materials. The hole-breaking device can relieve the hardening caused by the long-term deposition of the materials. The sludge conveying silo and the screw conveyor pump are used in combination to convey the materials to various positions. The silo body is easy to install, safe and reliable, and is an ideal bulk storage tank for various mixing plants.

[0003] The existing patent (publication number: CN212798071U) discloses a cement overflow device for a cement silo. By setting an overflow hole, an overflow pipe and an overflow collection tank, when the cement in the cement silo body is nearly full, the cement will flow into the overflow collection tank along the overflow pipe through the overflow hole, thus avoiding spraying outside the silo, causing waste and pollution. By setting a baffle plate, it can prevent the cement scattered during feeding from entering the overflow collection tank through the overflow hole and causing misjudgment. By setting a rotating motor and a rotating rod, the top of the cement in the storage cavity can be kept horizontal, and there will be no problem of the middle protruding and the two sides being lower, avoiding the excessive accumulation in the middle and causing overflow outside the silo. By setting a negative plate and a positive column, when the weight of the overflowed cement flowing into the overflow collection tank increases, the positive column will move down and contact the negative plate, so that the warning horn is powered on to give an alarm, reminding the staff to deal with it in time. Until the excess cement in the overflow collection tank is completely processed and discharged, the alarm will be disconnected, ensuring timely processing, so as to achieve the purpose of avoiding the overflow of cement outside the cement silo, causing environmental pollution and product waste, and effectively solving the problem that when the bulk cement transport vehicle fills the independent cement silo with cement, once it is full, if not dealt with in time, the cement will break through the dust-proof exhaust device on the top of the silo and overflow, spraying outside the silo, causing waste and pollution.

[0004] However, the above equipment still has certain deficiencies. First, as can be seen from the figure, the overflow port of the equipment and the rotating rod are not in the same horizontal position. Because the fluidity of cement is not as good as that of liquid, only a small part of the overflowed cement located at the overflow port can flow out of the cement silo through the pipeline and into the overflow collection tank in a short time. The rate of the overflowed cement entering the overflow collection tank is too low, and there may still be a problem of cement overflow and waste and pollution when a large amount of cement is fed into the cement silo in a short time. Therefore, it is necessary to optimize and improve the front-end feeding part of the overflow device. For this reason, a cement overflow device for a cement silo is proposed.

[0007] By adopting the above technical solution, the overflowing cement is continuously agitated and tumbled by multiple groups of flat plates, and then the cement is pushed by the guide plates to the position of the inner wall of the silo body. When it rotates to the position of the overflow pipe orifice, it is squeezed and sent into the interior of the overflow device, and then this cycle is repeated to achieve the rapid diversion of the cement overflowing to a predetermined height inside the silo body, and improve the rate of the overflowing cement entering the interior of the overflow device.

[0010] Further, on the curved outer wall of the fixed sleeve, multiple groups of connecting rods are fixedly arranged at equal intervals around the center of the circle, and the other end of each group of connecting rods is fixedly connected to the inner side wall of the fixed ring.

[0012] Further, the outer side wall of the fixed ring is in contact with the inner wall of the silo body, the lowest position of each group of guide plates is at the same horizontal line as the overflow pipe orifice, and each group of guide plates is inclined.

[0013] By adopting the above technical solution, the fixing ring can connect multiple groups of guide plates, and fitting the inner wall of the bin can strengthen the limiting strength, thereby improving the stability during rotation. Each group of the guide plates is inclined to push the overflowed cement to the position of the inner wall of the bin according to the inclined direction, increasing the contact rate with the overflow pipe orifice, and thus improving the outflow rate of the overflowed cement.

[0014] Further, one side wall of one end of the guide plate fits the inner wall of the bin, and a rubber soft sheet is fixedly arranged at the position where it fits the inner wall of the bin.

[0015] By adopting the above technical solution, fixedly arranging a rubber soft sheet at the position where one side wall of one end of the guide plate fits the inner wall of the bin can reduce the friction with the inner wall of the bin and improve the service life of the equipment.

[0016] Further, a plurality of stirring rods are fixedly connected to the curved outer wall of the rotating shaft below the fixed sleeve, and a plurality of planetary stirring rods are rotatably connected to the outer walls of the plurality of stirring rods.
