Fig. 1 is a schematic structural diagram of a lime sampling system 1 provided in this embodiment. Referring to fig. 1, a lime sampling system 1 provided in this embodiment includes a conveying pipe 11 and a lime sampling device 12, where the conveying pipe 11 can convey lime powder and convey the lime powder to a storage area. Lime sampling device 12 can extract lime powder from conveying pipe 11, and follow-up staff can detect the activity index of the lime powder who extracts. This lime sampling device 12 can replace the manual work to draw lime powder, has improved lime powder effectively and has drawed the work efficiency of operation, has reduced staff's intensity of labour.

Specifically, referring to fig. 1, the lime sampling device 12 includes a sampling head 121, a connecting pipe 122, a separator 123 and a collector 124, wherein an input end of the sampling head 121 is communicated with the conveying pipe 11, an output end of the sampling head 121 is communicated with an input end of the connecting pipe 122, an input end of the separator 123 is connected with an output end of the connecting pipe 122, and an input end of the collector 124 is connected with an output end of the separator 123 to receive lime powder output from the collector 124.

It should be noted that, in this embodiment, the air pressure in the separator 123 is smaller than the air pressure at the input end of the sampling head 121, so that, in the case that the input end of the sampling head 121 is communicated with the conveying pipe 11, the lime powder in the conveying pipe 11 can enter the separator 123 through the sampling head 121 and the connecting pipe 122, the separator 123 can input the lime powder into the collector 124 again, the sampling operation of the lime powder is completed, and the lime powder in the collector 124 can be used as a sample for the subsequent activity index detection. Therefore, the lime sampling device 12 can complete the lime powder sampling operation rapidly without the assistance of workers, so that the working efficiency of the lime powder sampling operation is improved, and the labor intensity of the workers is reduced.

It is noted that during the sampling of the lime powder, the input end of the sampling head 121 communicates with the conveying pipe 11. The air pressure at the input end of the aforementioned sampling head 121 can also be understood as the air pressure within the delivery tube 11.

Alternatively, it may be employed to draw the gas within the separator 123 such that a negative pressure is created within the separator 123, thereby resulting in the gas pressure within the separator 123 being less than the gas pressure at the input end of the sampling head 121. Alternatively, air may be pumped into the input end of the sampling head 121 or into the delivery tube 11 such that a positive pressure is created at the input end of the sampling head 121 or within the delivery tube 11, resulting in a lower air pressure within the separator 123 than at the input end of the sampling head 121.

Fig. 2 is an enlarged schematic view of a point a in fig. 1. Referring to fig. 1 and 2, in the present embodiment, the sampling head 121 includes a driving cylinder 1211 and a transition tube 1212, the driving cylinder 1211 is mounted on the connecting tube 122, and the transition tube 1212 is connected to a piston rod of the driving cylinder 1211. In practical applications, the driving cylinder 1211 is activated to drive the transition tube 1212 to reciprocate along the length direction of the connecting tube 122.

Alternatively, the driving cylinder 1211 may be an electric cylinder, a hydraulic cylinder, or the like.

It should be noted that, in this embodiment, the output end of the transition tube 1212 is communicated with the connecting tube 122, and the input end of the transition tube 1212 can extend into or out of the conveying tube 11 under the driving action of the driving cylinder 1211. It is understood that in the case that the input end of the transition pipe 1212 extends into the conveying pipe 11, the lime powder in the conveying pipe 11 can enter the connecting pipe 122 through the transition pipe 1212. When the input end of the transition tube 1212 extends out of the conveying tube 11, the input end of the transition tube 1212 is disconnected from the conveying tube 11, and the lime powder moves only in the conveying tube 11 and does not enter the connecting tube 122 through the transition tube 1212.

Generally, in practical applications, after the driving cylinder 1211 drives the input end of the transition tube 1212 to extend into the conveying tube 11, the driving cylinder 1211 stops working for 10-20 seconds, and after 10-20 seconds, the driving cylinder 1211 is started again, and then the input end of the transition tube 1212 extends out of the conveying tube 11, and the extracted lime powder has a weight of about 500g, so as to complete the operation of extracting the lime powder sample from the conveying tube 11.

It should be noted that in fig. 1 and 2, in the present embodiment, the lime powder moves from bottom to top in the conveying pipe 11, and the input port 12121 in fig. 2 can be understood as an input end of the transition pipe 1212. Moreover, in the present embodiment, the input port 12121 of the transition pipe 1212 is disposed at the lower portion of the transition pipe 1212, so that the lime powder moving from bottom to top can be conveniently input into the transition pipe 1212 through the input port 12121, and the lime powder in the conveying pipe 11 can be conveniently extracted.

Referring to fig. 1 and 2, in the embodiment, the connecting pipe 122 is inclined relative to the vertical direction, and the height of the input end of the connecting pipe 122 is higher than the height of the output end of the connecting pipe 122, which is beneficial to conveying lime powder from the input end of the connecting pipe 122 to the output end of the connecting pipe 122, so as to improve the speed of the lime powder entering the separator 123.

Referring to fig. 1 and 2, in the present embodiment, the sampling head 121 further includes a second blowing member 1213, and the second blowing member 1213 is mounted on the connecting pipe 122. Generally, after the lime powder enters the separator 123 through the connection pipe 122, a part of the lime powder may remain in the connection pipe 122. In this case, the second blowing unit 1213 may be activated and the second blowing unit 1213 may blow air into the connection pipe 122, so that the lime powder remaining in the connection pipe 122 may be blown into the separator 123, reducing waste of the lime powder.

Alternatively, the second blowing member 1213 may be a blower, an air gun, or the like.

Fig. 3 is an enlarged schematic view of fig. 1 at B. Referring to fig. 1 and fig. 3, in the present embodiment, the lime sampling device 12 further includes a third valve 125, the third valve 125 is installed on the connection pipe 122, and the third valve 125 can control the connection and disconnection of the connection pipe 122. It will be appreciated that, with the connecting pipe 122 in communication, lime powder may be transported from within the connecting pipe 122 into the separator 123. In case the connection pipe 122 is disconnected, the third valve 125 may block the lime powder from entering the separator 123.

Referring to fig. 1 and 3, in the present embodiment, the separator 123 includes a housing 1231, the housing 1231 is provided with an accommodating cavity 12311, a feeding port 12312 and a discharging port 12313 which are communicated with each other, the feeding port 12312 is communicated with the output end of the connecting pipe 122, and the discharging port 12313 is communicated with the input end of the collector 124. That is, the lime powder output from the connection pipe 122 may enter the accommodating chamber 12311 from the feeding port 12312 and then enter the collector 124 through the discharge port 12313.

In fig. 3, the feeding port 12312 is disposed on the side wall of the housing 1231, and the discharging port 12313 is disposed on the bottom wall of the housing 1231, so that the lime powder in the feeding port 12312 can directly drop to the discharging port 12313, and the conveying efficiency of the lime powder is improved.

In this embodiment, the separator 123 further includes a first valve 1232, the first valve 1232 is installed on the housing 1231, and the first valve 1232 can control the opening and closing of the outlet 12313. It will be appreciated that with the first valve 1232 open, the lime powder in the containing chamber 12311 can enter the collector 124 through the outlet port 12313. With the first valve 1232 closed, the discharge port 12313 is disconnected from the input end of the collector 124, and the first valve 1232 can block the lime powder in the accommodating chamber 12311 from entering the collector 124.

It can be understood that, under the pushing action of the air pressure, the lime powder gradually enters the accommodating cavity 12311, the gas also gradually enters the accommodating cavity 12311, and the air pressure in the accommodating cavity 12311 gradually increases, which easily causes the case 1231 to crack. To this end, referring to fig. 1 and fig. 3, in the present embodiment, the separator 123 further includes a pressure relief valve 1233, the housing 1231 is further provided with a first air outlet 12314, the first air outlet 12314 is communicated with the accommodating cavity 12311, and the pressure relief valve 1233 is disposed at the first air outlet 12314. Like this, after the atmospheric pressure value in holding chamber 12311 reaches certain numerical value, relief valve 1233 is opened, and gaseous first gas outlet 12314 output can be followed to gaseous atmospheric pressure in avoiding holding chamber 12311 lasts the increase, avoids casing 1231 the condition of breaking to appear.

In actual use, the air pressure value to which the pressure relief valve 1233 is opened may be set according to requirements, and the specific air pressure value to which the pressure relief valve 1233 is opened is not specifically limited in this embodiment.

It should be noted that lime powder may be mixed in the gas during the gas passes through the first outlet 12314, and thus the lime powder may be discharged to the external environment, which not only wastes the lime powder, but also pollutes the external environment. To this end, referring to fig. 1 and 3, in this embodiment, the separator 123 further includes a first filter bag 1234, the first filter bag 1234 is connected to the housing 1231, and the first filter bag 1234 is covered at the first outlet 12314. Therefore, the first filter bag 1234 can filter the gas passing through the first gas outlet 12314, and intercepts the lime powder mixed in the gas, thereby reducing the waste of the lime powder and avoiding the pollution of the lime powder to the external environment.

Referring to fig. 1 and 3, in the present embodiment, the separator 123 further includes a first blowing member 1235, and the first blowing member 1235 can blow air toward the accommodating chamber 12311. It will be appreciated that, when the lime powder enters the accommodating chamber 12311 from the connecting pipe 122, the driving cylinder 1211 drives the transition pipe 1212 to extend out of the conveying pipe 11, in which case the lime powder entering the accommodating chamber 12311 may not have enough power to be output from the outlet 12313 and deposited on the bottom wall of the housing 1231. And the first blowing member 1235 is actuated to blow the lime powder deposited on the bottom wall of the housing 1231 to provide power for the movement of the lime powder, and the auxiliary lime powder smoothly enters the collector 124 through the outlet 12313.

Alternatively, the first blowing part 1235 may be a blower, an air gun, or the like.

It can be understood that, in the process of blowing the first blowing piece 1235 toward the inside of the accommodating cavity 12311, a large amount of gas enters the accommodating cavity 12311, and the gas pressure inside the accommodating cavity 12311 will gradually increase, which easily causes the case 1231 to break. To this end, referring to fig. 1 and fig. 3, in the present embodiment, the housing 1231 is further provided with a second air outlet 12315, and the second air outlet 12315 is communicated with the accommodating cavity 12311. In this way, after the auxiliary lime powder is output from the discharge port 12313, the gas blown into the accommodating cavity 12311 can be discharged out of the accommodating cavity 12311 through the second gas outlet 12315, so that the pressure in the accommodating cavity 12311 is prevented from continuously increasing, and the case 1231 is prevented from being cracked.

It should be noted that lime powder may be mixed in the gas during the gas passes through the second gas outlet 12315, and thus the lime powder may be discharged to the external environment, which not only causes waste of the lime powder, but also pollutes the external environment. To this end, referring to fig. 1 and 3, in this embodiment, the separator 123 further includes a second filter bag 1236, the second filter bag 1236 is connected to the housing 1231, and the second filter bag 1236 is covered on the second air outlet 12315. Therefore, the second filter bag 1236 can filter the gas passing through the second gas outlet 12315, and intercept the lime powder mixed in the gas, so that the waste of the lime powder is reduced, and the pollution of the lime powder to the external environment is avoided.

Referring to fig. 1 and fig. 3, in the present embodiment, the separator 123 further includes a vibrating member 1237, the vibrating member 1237 is installed on the housing 1231, and the housing 1231 can be driven to vibrate by the vibrating member 1237. Therefore, in the vibration process of the shell 1231, the lime powder attached to the inner wall of the shell 1231 can be oscillated and dropped, so that the lime powder attached to the inner wall of the shell 1231 is reduced, and the waste of the lime powder is reduced.

Alternatively, the vibrating member 1237 may be a piston-type vibrator, a vibrating bed, or the like.

To sum up, the working principle of the lime sampling system 1 provided by the embodiment is as follows:

the conveying pipe 11 continuously conveys the lime powder upwards, the third valve 125 is opened, the driving cylinder 1211 is started, the driving cylinder 1211 drives the input end of the transition pipe 1212 to extend into the conveying pipe 11, part of the lime powder enters the connecting pipe 122 from the transition pipe 1212 and enters the accommodating cavity 12311 from the connecting pipe 122, and after 10-20 seconds, the driving cylinder 1211 is controlled to drive the input end of the transition pipe 1212 to extend out of the conveying pipe 11, so that the input end of the transition pipe 1212 is disconnected from the conveying pipe 11. During the process of the lime powder entering the accommodating cavity 12311, if the air pressure in the accommodating cavity 12311 is too large, the pressure relief valve 1233 is opened, and the air is discharged from the first air outlet 12314.

After the lime powder enters the accommodating cavity 12311, the third valve 125 is closed, the first valve 1232, the second valve 1238 and the first blowing piece 1235 are opened, the vibrating piece 1237 and the first blowing piece 1235 are started, the shell 1231 vibrates, the first blowing piece 1235 blows air into the accommodating cavity 12311, the lime powder in the accommodating cavity 12311 is driven by the air to enter the collector 124 through the discharge hole 12313, in addition, the blown air can be discharged through the second air outlet 12315, and the phenomenon that the air pressure in the accommodating cavity 12311 is too large is avoided.

After all the lime powder in the accommodating chamber 12311 is input into the collector 124, the third valve 125 and the second blowing member 1213 are opened to blow the lime powder remaining in the connecting pipe 122 into the accommodating chamber 12311, and the lime powder entering the accommodating chamber 12311 can enter the collector 124 through the discharge port 12313.

The above description is only exemplary of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
