[0042] In addition, if the terms "first", "second" and the like appear, they are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0043] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0044] Please refer to Figure 1 and Figure 2 The sample pneumatic conveying transceiver device 100 provided by the embodiments of the present application comprises a cabinet 110, a bottom lifting mechanism 120, a top lifting air pipe 130, a top lifting mechanism 140, a moving sliding sleeve 150, a top air pipe 160, a turnover control mechanism 170, a turnover pipe 180 and a blowing pipe 190.

[0045] The top lifting air pipe 130 is arranged at the lower part of the cabinet 110, the bottom lifting mechanism 120 is arranged below the top lifting air pipe 130 for controlling the lifting of the top lifting air pipe 130, and the blowing pipe 190 is in communication with the top lifting air pipe 130.

[0046] The top air pipe 160 is arranged at the top of the cabinet 110, the moving sliding sleeve 150 is sleeved at the bottom end of the top air pipe 160, and the top lifting mechanism 140 is connected with the moving sliding sleeve 150 for controlling the lifting of the moving sliding sleeve 150.

[0047] The turnover pipe 180 is arranged in the cabinet 110 and connected with the turnover control mechanism 170, and the turnover control mechanism 170 is used for controlling the turnover pipe 180 to present a horizontal or vertical state.

[0048] When the turnover pipe 180 presents a vertical state, the central axis of the turnover pipe 180, the central axis of the top lifting air pipe 130 and the central axis of the top air pipe 160 are on the same straight line, and the bottom lifting mechanism 120 can control the top lifting air pipe 130 to rise to the top end of the top lifting air pipe 130 closely to one end of the turnover pipe 180, and the top lifting mechanism 140 can control the moving sliding sleeve 150 to descend to the bottom end of the moving sliding sleeve 150 closely to the other end of the turnover pipe 180.

[0049] The cabinet body 110 is also equipped with a cabinet door 111. When the flip tube 180 is in a horizontal state, the position of its end corresponds to the cabinet door 111.

[0050] like Figures 1-4 As shown, before using the device, one end of the conveying air duct 101 is connected to the top air duct 160 via the air duct flange 102. When the tilting tube 180 is in a horizontal state, the operator places the container containing the sample 30 into the tilting tube 180. Then, the tilting tube 180 is tilted to a vertical state by the tilting tube 180 control mechanism. The cabinet door 111 is closed. The top of the lifting air duct 130 is pressed tightly against the bottom of the tilting tube 180 by the bottom lifting mechanism 120. The bottom of the moving sliding sleeve 150 is abutted against the top of the tilting tube 180 by the top lifting mechanism 140. At this time, the lifting air duct 130, the tilting tube 180, and the top air duct 160 are connected to form a conveying channel. The air supply duct 190 is connected to an external fan. The fan is started, and the air supply duct 190 supplies air into the lifting air duct 130. The container of sample 30 is sent out of the sample pneumatic conveying transceiver 100 from the top air duct 160 under the action of wind, and finally arrives at the other end of the conveying air duct 101. If the other end of the conveying air duct 101 is also connected to a sample pneumatic conveying transceiver 100, then sample 30 will be received by the sample pneumatic conveying transceiver 100 at the other end of the conveying air duct 101. When this device receives the sample 30, the flip tube 180 is in a vertical state. After the sample 30 is received, the bottom lifting mechanism 120 of the receiving transceiver 120 controls the top lifting air duct 130 to descend, the top lifting mechanism 140 controls the moving sliding sleeve 150 to rise, and then the flip control mechanism 170 flips the vertical flip tube 180 to a horizontal state. At this time, the cabinet door 111 can be opened to take out the container containing sample 30.

[0051] Therefore, the pneumatic sample conveying and receiving device 100 provided in this application embodiment can realize the pneumatic conveying and receiving of samples 30 or articles. When the pneumatic sample conveying and receiving device 100 provided in this application embodiment is applied to the conveying of steel bar samples 30, the pneumatic sample conveying and receiving device 100 is set in the workshop, one end of the conveying air duct 101 is connected to the top air duct 160 of the pneumatic sample conveying and receiving device 100, and the other end is led into the laboratory. After air is supplied to the lifting air duct 130, the sample 30 can be quickly and conveniently conveyed from the workshop to the laboratory. If the laboratory is also equipped with a pneumatic sample conveying and receiving device 100 connected to the conveying air duct 101, the laboratory staff can receive steel bar samples 30 through the device, or convey steel bar samples 30 or articles that can be placed in the sample container 20 back to the workshop through the device.

[0052] The application is particularly suitable for long steel sample 30, for example, the length of the steel sample reaches 600 mm, the length of the container reaches 660 mm, the weight of the container plus the steel sample reaches 9 kg, through the device provided by the application, convenient sample delivery can be realized, compared with manual sample delivery, the sample delivery time is greatly shortened, the sample delivery efficiency is improved, the sample delivery difficulty is reduced, and the manual work false situation is avoided, which greatly improves the application of the steel plant automation and production efficiency.

[0053] It should be noted that the device provided by the application will not have a conveying obstacle due to the length of the sample 30 or the length of the container. For the case that the sample 30 or the container is relatively long, a bend with a large inner diameter and a large radius is arranged at the turning position of the conveying air pipe 101, which can ensure that the sample container will not be stuck at the turning position.

[0054] Preferably, the sample pneumatic conveying transceiver device 100 further comprises a buffer 131 arranged at the top of the jacking air pipe 130, the buffer 131 is coaxial with the jacking air pipe 130, the cross section of the buffer 131 is circular, and the diameter is smaller than the inner diameter of the turnover pipe 180.

[0055] When the receiving end is provided with the sample pneumatic conveying transceiver device 100, the sample 30 reaches the turnover pipe 180 under the action of wind force, and the speed of the sample container 20 is relatively fast, which can reach 7-10 m / s. When the sample container 20 reaches, the bottom of the sample container 20 will have a strong impact with the bottom of the cabinet 110, which may cause damage to the sample container 20 and the sample pneumatic conveying transceiver device 100. In order to avoid the above problems, the buffer 131 is arranged at the top of the jacking air pipe 130, the buffer 131 is made of elastic material, and when the sample container 20 reaches, the bottom of the sample container 20 impacts on the buffer 131, the buffer 131 can play a good buffering effect on the sample container 20, avoiding damage to the sample container 20 due to the impact.

[0056] When the turnover pipe 180 remains in the vertical working state, the buffer 131 is in the state of extending into the turnover pipe 180 from the bottom of the turnover pipe 180. When the turnover pipe 180 is to be turned from the vertical working state to the horizontal state, first, the buffer 131 is lowered to exit the turnover pipe 180 under the action of the bottom lifting mechanism 120, the top lifting mechanism 140 controls the ascending of the moving sleeve 150 away from the turnover pipe 180, and then the turnover control mechanism 170 works to make the turnover pipe 180 turn. Therefore, the arrangement of the buffer 131 can make the device resist the impact of samples with large mass and high speed.

[0057] Specifically, the bottom lifting mechanism 120 comprises a lifting platform 121, the jacking air pipe 130 is arranged on the lifting platform 121, a connecting rod 122 is arranged at a central position in the jacking air pipe 130, and a buffer 131 is connected with the connecting rod 122. The bottom lifting mechanism 120 comprises a bottom pneumatic cylinder 123, and a push rod of the bottom pneumatic cylinder 123 is connected with the lifting platform 121.

[0058] After high-pressure gas is introduced into the pneumatic cylinder, the push rod moves upward to push the lifting platform 121 to move upward, and then the jacking air pipe 130 moves upward.

[0059] Of course, it should be noted that, although the bottom lifting mechanism 120 is powered by the pneumatic cylinder in the embodiment, in other embodiments of the application, the bottom lifting mechanism 120 can also comprise a hydraulic cylinder or a screw lifting mechanism.

[0060] Preferably, a sealing ring is arranged on the top end face of the jacking air pipe 130, and when the jacking air pipe 130 is pushed to closely contact the turnover pipe 180, the sealing ring realizes sealing between the turnover pipe 180 and the jacking air pipe 130.

[0061] Preferably, the top lifting mechanism 140 comprises at least two top pneumatic cylinders 141, the at least two top pneumatic cylinders 141 are uniformly arranged around the top air pipe 160, the bottom end of the moving sleeve 150 has a connecting disc 151, the push rod of each top pneumatic cylinder is connected with the edge of the connecting disc 151, and the end of each top pneumatic cylinder away from the push rod is fixed to the top of the cabinet 110.

[0062] The number of the top pneumatic cylinders 141 can be 2, 3, 4, 5, etc., and in the scheme shown in the drawings, the number of the top pneumatic cylinders 141 is 2, and the two top pneumatic cylinders 141 are symmetrically arranged, and the two top pneumatic cylinders 141 work synchronously when the top lifting mechanism 140 works, and after high-pressure gas is introduced into the top pneumatic cylinder 141, the push rod pushes the moving sleeve 150 to move downward to make the lower end face of the connecting disc 151 closely contact the top end of the turnover pipe 180.

[0063] Of course, it should be noted that, although the top lifting mechanism 140 is powered by the pneumatic cylinder in the embodiment, in other embodiments of the application, the top lifting mechanism 140 can also comprise a hydraulic cylinder or a screw lifting mechanism.

[0064] Preferably, a sealing ring is arranged on the top end face of the turnover pipe 180, and when the moving sleeve 150 moves downward to make the lower end face of the connecting disc 151 closely contact the top end of the turnover pipe 180, the sealing ring realizes sealing between the turnover pipe 180 and the moving sleeve 150.

[0065] Further, a sealing ring is also arranged between the inner wall of the mobile sliding sleeve 150 and the outer wall of the top air pipe 160, which realizes the sealing between the mobile sliding sleeve 150 and the top air pipe 160.

[0066] Preferably, the turnover control mechanism 170 comprises a turnover cylinder 171, a first turnover shaft 172, a first turnover bearing 174, a second turnover shaft 173 and a second turnover bearing 175; the first turnover bearing 174 and the second turnover bearing 175 are arranged on the opposite two side walls of the cabinet body 110; one end of the first turnover shaft 172 is connected with the turnover cylinder 171 through the first turnover bearing 174, and the other end of the first turnover shaft 172 is connected with one side of the turnover pipe 180; the other side of the turnover pipe 180 is connected with one end of the second turnover shaft 173, and the other end of the second turnover shaft 173 is connected with the second turnover bearing 175; the first turnover bearing 174, the first turnover shaft 172, the second turnover shaft 173 and the second turnover bearing 175 are coaxially arranged.

[0067] The turnover cylinder 171 provides power for the turnover of the turnover pipe 180, and the two bearings respectively serve to limit the two turnover shafts on the inner wall of the cabinet body 110. When the turnover cylinder 171 is started, the first turnover shaft 172 rotates to drive the turnover pipe 180 to perform a turnover movement.

[0068] Preferably, the turnover cylinder 171 is provided with a turnover state monitoring module, and an electromagnetic lock is arranged on the cabinet door 111 and is in communication connection with the turnover state monitoring module of the turnover cylinder 171; the electromagnetic lock controls the opening and closing of the cabinet door 111 by receiving the state signal of the turnover pipe 180 sent by the turnover state monitoring module; when the turnover state monitoring module monitors that the state of the turnover pipe 180 is a vertical state, the electromagnetic lock is locked, the cabinet door 111 is closed and cannot be opened, and when the turnover state monitoring module monitors that the state of the turnover pipe 180 is a horizontal state, the electromagnetic lock is unlocked, and the cabinet door 111 can be opened.

[0069] Further, a vertical limiting block 112 is arranged in the cabinet body 110, and in the scheme shown in the drawings, the vertical limiting block 112 is arranged above the inner wall opposite to the cabinet door 111 in the cabinet body 110. When the turnover pipe 180 is turned from a horizontal state to a vertical state and is turned to a vertical state, the turnover pipe 180 just abuts against the vertical limiting block 112, which can avoid that the turnover pipe 180 is excessively turned to be unable to be aligned with the mobile sliding sleeve 150 and the top lifting air pipe 130.

[0070] Further, a horizontal limiting block 113 is arranged in the cabinet 110, in the scheme shown in the drawings, the horizontal limiting block 113 is arranged near the cabinet door 111 in the cabinet 110. When the turnover tube 180 is turned from the vertical state to the horizontal state, the turnover tube 180 abuts against the horizontal limiting block 113 when turned to the horizontal state, so that the turnover tube 180 is prevented from being turned too much to deviate from the cabinet door 111, thereby making it difficult to send or take out the sample container 20.

[0071] Preferably, the air supply pipe 190 has a spring hose pipe section 191.

[0072] Since the air supply pipe 190 is connected with the jacking air pipe 130, the jacking air pipe 130 is lifted and lowered under the action of the bottom lifting mechanism 120, so the air supply pipe 190 needs to have the telescopic property, and the spring hose pipe section 191 can make the air supply pipe 190 have a certain telescopic property.

[0073] Preferably, a detector for detecting whether there is a sample 30 in the turnover tube 180 is further arranged in the cabinet 110. Further, the detector is arranged above the turnover tube 180, and the detector is a reflection type detection photoelectric element 114.

[0074] The reflection type detection photoelectric element 114 can detect whether there is a sample 30 in the turnover tube 180, so as to determine whether the receiving or sending is successful.

[0075] The embodiment of the application further provides a sample pneumatic conveying receiving and sending device 100 set, which comprises a sample container 20 and the sample pneumatic conveying receiving and sending device 100 provided by the embodiment of the application.

[0076] The inner diameter of the turnover tube 180 is greater than the outer diameter of the sample container 20, and a limiting ring 181 is coaxially arranged at the bottom end of the turnover tube 180, and the inner diameter of the limiting ring 181 is smaller than the inner diameter of the turnover tube 180. When the turnover tube 180 is in the horizontal state, the sample container 20 can be inserted into the turnover tube 180 from the top end of the turnover tube 180, and is limited by the limiting ring 181 to ensure that it does not pass out from the bottom end of the turnover tube 180.

[0077] Further, a container cover 21 is detachably arranged at the top of the sample container 20. After the sample 30 is put into the sample container 20, the container cover 21 is covered, and then the sample container 20 is placed in the turnover tube 180.

[0078] Taking the sample pneumatic conveying receiving and sending device 100 provided by the embodiment of the application as an example, the working mode is as follows:

[0079] When it is needed to send the steel bar sample, for example, Figure 3As shown, at this time, the piston of the bottom pneumatic cylinder 123 is retracted, driving the buffer 131 and the lifting air pipe 130 to fall; the piston of the upper top pneumatic cylinder 141 is retracted, driving the moving sliding sleeve 150 to slide upward; after the top pneumatic cylinder 141 and the bottom pneumatic cylinder 123 are retracted to the position, the turnover cylinder 171 is actuated to drive the turnover pipe 180 to turn over to the horizontal position; at this time, the steel bar sample is manually loaded into the sample container 20, the container cover 21 is tightened, the steel bar sample 30 is sealed into the sample container 20, and the loading is completed.

[0080] After the loading is completed, the cabinet door 111 is closed, as shown in the figure. Figure 4 As shown, the turnover cylinder 171 is actuated to drive the turnover pipe 180 to turn over from the horizontal state to the vertical state, and at the same time, the turnover pipe 180 turns over the sample container 20 loaded with the steel bar sample 30 to the vertical position; after turning over to the vertical position, the piston rod of the upper top pneumatic cylinder 141 is extended, driving the moving sliding sleeve 150 to slide downward and tightly contact with the upper pipe opening of the turnover pipe 180; the piston of the lower bottom pneumatic cylinder 123 is extended, the lifting platform 121 is lifted, driving the buffer 131 and the lifting air pipe 130 to act upward, the lifting air pipe 130 is tightly flat with the lower pipe of the turnover pipe 180, and the buffer 131 is extended into the turnover pipe 180, the sample container 20 is lifted into the top air pipe 160, and after the sample container 20 is detected by the light emitting and detecting photoelectric 114, the external power fan is started to blow air from the air inlet pipe into the bottom of the sample container 20 to generate air pressure, blow the sample container 20 into the conveying air pipe 101, and the sample container 20 runs in the conveying air pipe 101 to reach the sample pneumatic conveying receiving and sending device 100 at the other end for receiving.
