This cement overflow device for a cement silo is convenient for overflow warning of the device, preventing excessive overflow of the device from causing economic losses to people, increasing the use efficiency and practicality of the device, prolonging the service life of the device, and facilitating people to use the device.

[0004] Although the above-mentioned cement overflow device for a cement silo can achieve the effect of overflow warning through the settings of the connecting pipe and the overflow silo, etc., in actual application, there are still the following deficiencies: The preset height of the overflow of the cement silo cannot be adjusted, often resulting in a large amount of cement automatically entering the overflow silo through the connecting pipe, and the cement collected and stored in the overflow silo is difficult to enter the cement silo again for utilization. Summary of the Utility Model

[0005] The purpose of the utility model is to propose a cement overflow device for a cement silo aiming at the problems existing in the background art.

[0006] To achieve this purpose, the utility model adopts the following technical solutions: A cement overflow device for a cement silo includes a cement silo body. A feed pipe is fixedly inserted at the top of the cement silo body, a discharge pipe is fixedly inserted at the bottom of the cement silo body, a storage component is fixedly installed on the periphery of the cement silo body. The storage component includes an overflow silo fixedly installed on the outer wall of the cement silo body.

[0023] Embodiment 1

[0024] As Figures 1-4 shown, a cement overflow device for a cement silo proposed by the present utility model includes a cement silo body 1. A feed pipe 11 is fixedly inserted at the top of the cement silo body 1, and a discharge pipe 12 is fixedly inserted at the bottom of the cement silo body 1. A storage assembly 2 is fixedly installed on the periphery of the cement silo body 1. The storage assembly 2 includes an overflow bin 21 fixedly installed on the outer wall of the cement silo body 1. An overflow pipe 22 is fixedly inserted at the top of the overflow bin 21. One side of the overflow pipe 22 away from the overflow bin 21 is communicated with the upper part of the periphery of the cement silo body 1. An opening and closing assembly 3 for opening and closing the overflow pipe 22 is provided on the top wall of the cement silo body 1, and an exhaust assembly 4 is fixedly inserted on the top wall of the cement silo body 1.

[0025] In this embodiment: The opening and closing assembly 3 includes two limit slide bars 31 fixedly installed on the inner wall of the top of the cement silo body 1. A moving plate 32 is slidably sleeved around the limit slide bars 31. A closing plate 33 is fixedly installed at the bottom of the moving plate 32, and the closing plate 33 is in contact with the inner wall of the cement silo body 1. Through this setting, the moving plate 32 can be limited to rise and fall around the two limit slide bars 31. At the same time, the moving plate 32 can drive the closing plate 33 to rise and fall along the inner wall of the cement silo body 1. A through hole 34 is formed in the closing plate 33, and the through hole 34 is matched with the overflow pipe 22. Through this setting, when the through hole 34 is communicated with the overflow pipe 22, the cement inside the cement silo body 1 enters the overflow pipe 22 through the through hole 34, and the bottom side of the through hole 34 is the highest height of the cement inside the cement silo body 1. A threaded rod 35 is rotatably installed on the top wall of the cement silo body 1. The bottom end of the threaded rod 35 penetrates through the top wall of the cement silo body 1 and extends into the cement silo body 1, and is rotatably connected to the top of the moving plate 32. The top end of the threaded rod 35 is fixedly connected with a turntable 36. Through this setting, the threaded rod 35 is threadedly engaged with the top wall of the cement silo body 1. By rotating the turntable 36, the threaded rod 35 can be rotated and lifted on the top wall of the cement silo body 1, thereby driving the moving plate 32 to rise and fall, and further controlling the height of the closing plate 33. When the closing plate 33 completely abuts against one side of the overflow pipe 22 close to the cement silo body 1, the cement cannot enter the overflow bin 21 through the overflow pipe 22. When the through hole 34 on the closing plate 33 is communicated with the overflow pipe 22, the cement can enter the overflow pipe 22 through the through hole 34.

[0026] Embodiment 2

[0027] As Figures 1-4As shown in the figure, a cement overflow device for a cement silo proposed by the present utility model. Compared with the first embodiment, this embodiment further includes that a discharge pipe 23 is fixedly inserted at the bottom of the overflow bin 21, and one side of the discharge pipe 23 away from the overflow bin 21 is communicated with the outer bottom of the cement silo body 1. Through this setting, the cement stored in the overflow bin 21 can automatically flow back into the cement silo body 1 through the discharge pipe 23, avoiding the need for workers to transfer it into the cement silo body 1; a valve 24 is provided on the discharge pipe 23. Through this setting, the opening and closing of the discharge pipe 23 can be controlled by controlling the valve 24; the exhaust assembly 4 includes an exhaust cylinder 41 fixedly inserted on the top wall of the cement silo body 1. A piston 42 is movably sleeved inside the exhaust cylinder 41. A spring 43 is fixedly connected between the inner top wall of the exhaust cylinder 41 and the piston 42. An exhaust pipe 44 is fixedly inserted on the periphery of the exhaust cylinder 41, and the exhaust pipe 44 is located above the piston 42. Through this setting, when the air pressure inside the cement silo body 1 is too high, the piston 42 will rise inside the exhaust cylinder 41, and at the same time the spring 43 is compressed and deformed. When the height of the piston 42 is higher than the exhaust pipe 44, the gas inside the cement silo body 1 is discharged. At the same time, after the spring 43 loses the extrusion force, it will reset, thereby pushing the piston 42 to descend and reset.

[0028] Working principle: When using this device, cement is introduced into the cement silo body 1 through the feed pipe 11. Rotate the turntable 36 to drive the threaded rod 35 to rotate and lift on the top wall of the cement silo body 1, thereby driving the moving plate 32 to lift along the two limit slide rods 31. The moving plate 32 drives the closing plate 33 to lift along the inner wall of the cement silo body 1. When the closing plate 33 completely fits the connection between the overflow pipe 22 and the cement silo body 1, the cement cannot enter the overflow bin 21 through the overflow pipe 22. When the through hole 34 is communicated with the overflow pipe 22, the cement inside the cement silo body 1 will enter the overflow pipe 22 through the through hole 34 and finally be collected and stored in the overflow bin 21. And the bottom side of the through hole 34 is the preset height of the cement overflow inside the cement silo body 1. When the cement inside the cement silo body 1 is almost used up, the valve 24 can be started to open the discharge pipe 23 to introduce the cement inside the overflow bin 21 into the cement silo body 1.
