[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides Figure 1-4 The automatic sampling device for powder conveying shown in the figure comprises a powder conveying pipe 1 and a body 3 installed on the lower side of the powder conveying pipe 1;

[0025] A guide pipe 6 is fixedly connected between the right end outer wall of the body 3 and the lower end outer wall of the powder conveying pipe 1;

[0026] A solenoid valve 7 is fixedly connected between the guide pipe 6 and the outer wall of the lower end of the powder conveying pipe 1;

[0027] The internal transmission connection of the solenoid valve 7 is connected with a valve core 19 to control the opening and closing of one end of the guide tube 6. The outer wall of the lower end of the fuselage 3 is clamped with a sampling bottle 4 to store the powder sample. The interior of the fuselage 3 is provided with a guide bin 10 to guide the powder to the sampling bottle 4. When sampling the powder, the normal movement of the powder inside the powder conveying pipe 1 is maintained. Then, after receiving the set signal, the solenoid valve 7 will control the valve core 19 to rotate the angle to open the right opening of the guide tube 6. The powder part flowing inside the powder conveying pipe 1 will be diverted through the guide tube 6. The valve core 19 is closed after being opened for a certain period of time. The powder entering the guide tube 6 will gradually move and fall into the guide bin 10. After that, it is guided into the sampling bottle 4 for the second time to complete the sampling. Then, the sampling bottle 4 is removed and analyzed and tested in the designated laboratory.

[0028] A delivery pipe a13 is provided inside the fuselage 3, and the outer wall of the right end of the delivery pipe a13 is integrally connected with the delivery pipe b9 to guide the flow of liquid. The outer walls of the lower ends of the delivery pipe a13 and the outer walls of the lower ends of the delivery pipe b9 are equidistantly provided from left to right with multiple nozzles 16 that penetrate downward into the guide bin 10 and the guide pipe 6 for liquid spraying. First, connect one end of the delivery pipe a13 to the water supply faucet, and then place the collection bucket under the fuselage 3. When the sampling is completed, the faucet can be turned on to allow the liquid to pass through the delivery pipe a13 and the delivery pipe b9, and spray out from the nozzle 16 to flush the guide pipe 6, the guide bin 10 and the lower end of the valve core 19, and flush the remaining powder outward and fall into the pre-prepared collection bucket. After the flushed water becomes clear, the faucet can be closed, and the sampling operation can be performed again after the interior is dried. At the same time, the delivery pipe a13 can be connected to the air gun, and the speed of internal drying can be accelerated by jetting.

[0029] like Figure 3 As shown, the inner walls of the lower ends of the delivery pipes a13 and b9 are fixedly connected with multiple fixed ends 14 at equal distances to limit the position of the nozzle 16, and a guide cylinder 15 is fixedly connected between the multiple fixed ends 14 and the nozzle 16. A diverter plate 18 is fixedly connected near the upper side between the inner walls of the left and right ends of the multiple nozzles 16 to divide the liquid into multiple columnar sprays, and a dustproof net 17 is fixedly connected to the lowermost side between the inner walls of the left and right ends of the multiple nozzles 16 to prevent dust from entering the inside of the nozzle 16.

[0030] When the delivery pipe a13 and the delivery pipe b9 are transporting liquid, the liquid enters the nozzle 16 through the guide tube 15, and is then divided into multiple columns for spraying out through the diverter plate 18, thereby increasing the contact space of the liquid inside the guide bin 10 and the guide pipe 6, speeding up the cleaning speed, and when not cleaned, the dust-proof net 17 can be used to prevent dust from clogging the diverter plate 18. At the same time, when the diverter plate 18 sprays water, the dust blocked on the dust-proof net 17 can be cleaned synchronously.

[0031] like Figure 2 As shown, the left end of the delivery pipe a13 is open and connected to the external water supply faucet, and the right end of the delivery pipe b9 is closed.

[0032] The open delivery pipe a13 can be connected between the faucet and the air gun for cleaning and drying operations, and the closed delivery pipe b9 at the right end can block the flow of liquid to avoid liquid waste.

[0033] like Figure 1 and Figure 2 As shown, a control panel 2 is embedded in the front outer wall of the fuselage 3, a connector 8 is fixedly connected between the fuselage 3 and the powder conveying pipe 1 to limit the position of the fuselage 3, a fixing plate 5 is fixedly connected to the lower outer wall of the fuselage 3, and a slot 11 is provided on the lower outer wall of the fixing plate 5.

[0034] Through the control panel 2, the opening angle and opening duration of the solenoid valve 7 control valve core 19 can be controlled, the position of the fuselage 3 can be limited by the connecting piece 8, and one end of the guide tube 6 can be connected to the position of the maximum powder flow of the powder conveying pipe 1.

[0035] like Figure 2 and Figure 4 As shown, the outer walls of the left and right ends of the sampling bottle 4 are fixedly connected to the inner blocks 12 of the card slot 11 to limit the position of the sampling bottle 4. The upper side of the guide chamber 10 is provided with a controller. The sampling bottle 4 is transparent, and the valve core 19 can be rotated clockwise or counterclockwise.

[0036] When fixing the sampling bottle 4, first insert the blocks 12 at the left and right ends of the sampling bottle 4 upward into the card slot 11, and rotate the sampling bottle 4 to complete the fixation of the sampling bottle 4. When removing the sampling bottle 4, rotate the same distance in the opposite direction of the fixed sampling bottle 4 to remove the sampling bottle 4. When passing through the controller, the program instructions input from the control panel 2 can be sent to the solenoid valve 7.

[0037] The implementation principle of this embodiment is as follows: when sampling powder, the normal movement of the powder inside the powder conveying pipe 1 is maintained, and then the solenoid valve 7 will control the valve core 19 to rotate the angle after receiving the set signal, and open the right opening of the guide pipe 6. The powder part flowing inside the powder conveying pipe 1 will be diverted through the guide pipe 6, and the valve core 19 will be closed after being opened for a certain period of time. The powder entering the guide pipe 6 will gradually move and fall into the inside of the guide bin 10, and then be guided into the sampling bottle 4 for the second time to complete the sampling. Then, the sampling bottle 4 can be removed and analyzed and tested in the designated laboratory. First, the powder conveying pipe 1 will be diverted through the guide pipe 6. One end of the delivery pipe a13 is connected to the water supply faucet, and then a collection bucket is placed under the fuselage 3. When the sampling is completed, the faucet can be turned on to allow the liquid to pass through the delivery pipe a13 and the delivery pipe b9 and spray out from the nozzle 16 to flush the guide pipe 6, the guide bin 10 and the lower end of the valve core 19, flushing the remaining powder outward and falling into the pre-prepared collection bucket. After the flushed water becomes clear, the faucet can be closed and the sampling operation can be performed again after the interior is dried. At the same time, the delivery pipe a13 can be connected to the air gun to speed up the internal drying by jetting.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
