[0022] See also Figure 1-Figure 3The automatic weighing and unloading cement silo of this embodiment can store bulk cement powder, and can realize automatic loading and discharging, reducing labor and transportation costs. It can also automatically control the unloading amount of cement powder during discharging to ensure the accuracy of the unloading amount, thereby ensuring the quality of the finished cement. In this embodiment, it mainly includes a base frame 1 and a storage bin 2, and the storage bin 2 is fixedly arranged on the base frame 1. At least one unloading port 6 is arranged at the bottom of the storage bin 2, and the unloading port 6 is an inverted cone structure. The cement powder in the storage bin 2 is accumulated at the inverted cone, which is convenient for unloading cement powder. A loading pipe 7 is fixedly arranged on the side of the storage bin 2 to facilitate the transportation of cement powder to the inside of the storage bin 2. A silo top dust collector 8 is fixedly arranged on the top of the storage bin 2. The silo top dust collector 8 is a mature existing technology and will not be described in detail here. When the cement powder is fed into the storage bin 2 through the loading pipe 7, the gas in the storage bin 2 is discharged through the silo top dust collector 8, which is convenient for feeding and avoids dust.

[0023] A control room 9 is fixedly provided on the side of the storage bin 2, a ladder 10 is fixedly provided on the side of the control room 9, a guardrail 11 is fixedly provided at the top edge of the control room 9, and a door 12 is hingedly provided at the front end of the control room 9. It is convenient for the staff to use and maintain the operation. An air compressor 13 is provided inside the control room 9. The air compressor 13 is a mature existing technology and will not be described in detail here. A plurality of air inlets 14 connected to the air compressor 13 through pipes are provided at the discharge port 6 at the bottom of the storage bin 2. By controlling the operation of the air compressor 13, air is blown into the inside of the discharge port 6 at the bottom of the corresponding storage bin 2 through the air inlet 14 to prevent cement powder from being blocked at the discharge port 6 and failing to discharge.

[0024] In order to achieve quantitative feeding control of cement powder. Figure 1-Figure 3 In this embodiment, a weighing hopper 3 for weighing cement powder is provided on the side of the base frame 1. A weighing sensor is provided inside the weighing hopper 3. The weighing hopper 3 is fixedly provided on the control room 9 and the lower part of the weighing hopper 3 is in an inverted cone structure. The cement powder is weighed by the weighing hopper 3, so that the discharge amount of the cement powder is automatically controlled to ensure the accuracy of the discharge amount, thereby ensuring the quality of the finished cement. The top of the weighing hopper 3 is connected and fixedly provided with a ventilation pipe 15 and a feed pipe 16. The ventilation pipe 15 is used to exhaust the inside of the weighing hopper 3 when pouring cement powder to avoid dust.

[0025] In order to realize automatic feeding. In this embodiment, see Figure 1 and Figure 2A feeding unit 4 for conveying cement powder to the weighing hopper 3 is fixedly arranged below the storage bin 2. The feeding unit 4 includes a feeding pipe 41 arranged horizontally below the storage bin 2. The upper part of the feeding pipe 41 is connected to the corresponding discharge port 6. A manual valve 42 is arranged between the feeding pipe 41 and the discharge port 6. The corresponding channel is closed or opened by the manual valve 42 to change the discharge speed according to demand. The end of the feeding pipe 41 is connected to a vertically arranged feed pipe 43. The top of the feed pipe 43 passes through the control chamber 9 and its outlet is softly connected to the feed pipe 16 of the weighing hopper 3 through a hose. The insides of the feeding pipe 41 and the feeding pipe 43 are both coaxially rotated with a spiral auger 44. The ends of the feeding pipe 41 and the feeding pipe 43 are both provided with a motor 45 for driving the spiral auger 44 to rotate. The spiral auger 44 is driven to rotate by controlling the motor 45 to realize the transportation of cement powder, which is convenient for subsequent quantitative discharge.

[0026] In order to achieve the change of the material feeding position. Figure 1 and Figure 3 , the bottom end of the weighing hopper 3 is connected with a discharge pipe 5. A rotating frame 17 is rotatably arranged inside the control room 9 through a bearing, and the discharge pipe 5 is rotatably arranged on the rotating frame 17. A connecting pipe 18 is spherically hinged at the upper end of one end of the discharge pipe 5 on the side of the rotating frame 17, and the weighing hopper 3 is softly connected to the top of the connecting pipe 18 through a hose through an automatic valve 19 fixed at its bottom end. The position of the outlet of the discharge pipe 5 is changed on the basis of continuous discharge, so that cement powder is discharged to different positions, which is convenient for the staff to operate. A telescopic pipe 20 is hingedly arranged at the bottom end of the middle part of the discharge pipe 5, and the other end of the telescopic pipe 20 is hingedly arranged with the side of the rotating frame 17. The telescopic pipe 20 consists of a straight rod and a sleeve. The sleeve part of the straight rod and the sleeve is provided with a through hole, and the length of the telescopic pipe 20 is fixed by inserting a bolt into the corresponding through hole. Therefore, the height of the outlet of the discharge pipe 5 is limited by changing the length of the telescopic pipe 20 to adapt to different site requirements. The spiral auger 44 is also arranged inside the discharge pipe 5 , and the motor 45 is also arranged at one end of the discharge pipe 5 on the side of the rotating frame 17 to drive the spiral auger 44 to rotate, and the other end of the discharge pipe 5 is fixedly provided with a discharge port 21 .

[0027] The method of using the automatic weighing and unloading cement silo of the utility model is as follows: first, cement powder is transported to the interior of the storage silo 2 through the feeding pipe 7. In this process, the gas in the storage silo 2 is discharged through the silo top dust collector 8, which is convenient for feeding and avoids dust. At this time, the cement powder in the storage silo 2 is accumulated at the inverted cone, which is convenient for unloading of cement powder. When it is necessary to discharge, the corresponding channel is closed or opened by the manual valve 42 to change the unloading speed according to the demand. Then the motor 45 at the end of the conveying pipe 41 and the feeding pipe 43 is controlled to work, and the corresponding spiral auger 44 is controlled to rotate, so that the cement powder entering the conveying pipe 41 from the unloading port 6 is transported to the inside of the weighing hopper 3 through the feeding pipe 43 and the feeding pipe 16. In this process, the air compressor 13 is controlled to work, so that the inside of the unloading port 6 at the bottom of the corresponding storage silo 2 is blown through the air inlet, so as to avoid the cement powder being blocked at the unloading port 6 and unable to unload. At the same time, the inside of the weighing hopper 3 when pouring cement powder is exhausted through the ventilation pipe 15 to avoid dust. When the cement powder enters the weighing hopper 3, the amount of the cement powder is detected and weighed by a weighing sensor, so that the discharge amount of the cement powder is automatically controlled to ensure the accuracy of the discharge amount, thereby ensuring the quality of the finished cement.

[0028] When it is necessary to discharge the material, the height of the discharge pipe is limited by the telescopic tube. During this process, the discharge pipe is always connected to the bottom of the weighing hopper through the connecting pipe. When the weight of the cement powder in the weighing hopper meets the requirements, the automatic valve is controlled to work and the channel is opened. At this time, the cement powder in the weighing hopper enters the discharge pipe through the connecting pipe. During this process, the motor is controlled to work and drive the spiral auger in the discharge pipe to rotate, so that the cement powder is discharged from the discharge port. When the cement powder is discharged, the rotating frame is rotated in the control room by rotating the discharge pipe, thereby changing the horizontal position of the discharge port.
