Description

Technical Field

[0001] The invention belongs to the technical field of reactors, in particular to a reactor sampling device capable of adjusting the sampling height. Background Art

[0002] A reactor is a device used for chemical reactions, physical and chemical processes, and laboratory research. It is widely used in pharmaceutical, chemical, food processing, and other fields. During the reaction process, it is necessary to sample the material inside the reactor. By sampling, the changes in the material during the reaction process can be monitored in real time, so as to understand the progress and efficiency of the reaction. This helps the operator to adjust the reaction conditions in a timely manner to ensure that the reaction proceeds in the intended direction.

[0003] The patent with announcement number CN209214981U discloses a sampling device for a reactor, which is used in the field of water reducer processing equipment. The key points of its technical solution are: it includes a sampling tube and a support frame arranged on the reactor body, a guide tube is passed through the support frame, and a fixing part for fixing the guide tube is provided on the support frame; a sampling cylinder is arranged in the guide tube, and a plurality of rollers that abut against the inner wall of the guide tube are arranged on the side wall of the sampling cylinder, a traction rope is connected to the sampling cylinder, and one end of the traction rope extends out of the guide tube; a sealing cover is connected to the guide tube by a plurality of fastening bolts. The advantage is that the operator sinks the sampling cylinder into the solution through the traction rope, and pulls the traction rope to lift the sampling cylinder out after it is filled with the solution. Sampling is quick, simple and convenient.

[0004] However, the above technical solution still has the following deficiencies in practical application: The sampling tube is sunk into the solution inside the reactor by a traction rope. After the sampling tube is filled with the solution, it is lifted out of the reactor. Although solutions at different depths can be sampled in this way, in some cases, in order to have a more comprehensive understanding of the conditions of the solution inside the reactor, it is necessary to sample solutions at different depths multiple times in succession. In order to achieve multiple sampling, the sampling tube needs to be removed from the reactor after completing a sampling work, and then the collected solution needs to be discharged before the next sampling work can be carried out. This increases the complexity and time cost of the operation and affects the sampling progress.

[0009] Preferably, a motor 1 is fixedly connected to one side of the upper end surface of the frame, and an output end of the motor 1 is fixedly connected to an upper end of a threaded rod 1.

[0010] Preferably, a solenoid valve is provided on one side of the liquid inlet pipe.

[0011] Preferably, a motor three is fixedly connected to the middle portion of the lower end surface of the fixing plate, and an output end of the motor three is fixedly connected to the bottom of the turntable.

[0012] Preferably, a threaded rod 2 is threadedly connected to one side of the turntable, both ends of the threaded rod 2 are rotatably arranged on the sleeve, a motor 5 is fixedly connected to one side of the upper end of the sleeve, and the output end of the motor 5 is fixedly connected to the upper end of the threaded rod 2.

[0013] Preferably, a cup cover and a gear are rotatably provided on one side of the upper end of the sampling cup via a rotating shaft, the gear is fixedly connected to the cup cover, a torsion spring is sleeved on the rotating shaft, and the torsion spring is used to reset the rotating shaft.

[0014] Preferably, a rack is slidably connected to one side of the upper end surface of the turntable through a slide rail, the rack and the gear are meshed with each other, an electric push rod is fixedly connected to one side of the upper end surface of the turntable, and the piston end of the electric push rod is fixedly connected to one end of the rack.

[0015] Preferably, a lifting plate is slidably connected to one side of the sleeve, and clamping blocks are slidably connected to both sides of the lower end of the lifting plate.

[0017] The beneficial effects of the present invention are as follows: 1. The reactor sampling device with adjustable sampling height described in the present invention is characterized in that the mounting base is installed on the top of the reactor by bolt mounting, and the sleeve is aligned with the opening on the top of the reactor. Then, a motor is used to drive the threaded rod to rotate, so that the connecting rod moves downward, so that the sleeve can be extended into the solution inside the reactor, and the solution does not exceed the top of the sleeve. When the liquid inlet pipe is at the depth required for sampling, the solenoid valve on the liquid inlet pipe is opened, and the solution flows into the sampling cup along the liquid inlet pipe, so that solution samples of different depths can be obtained by adjusting the sampling height, and the situation of the solution inside the reactor can be more comprehensively understood.

[0018] 2. The reactor sampling device capable of adjusting the sampling height of the present invention utilizes a multi-point storage mechanism, and by driving the turntable to rotate, the openings of the sampling cups at different positions are aligned with the liquid inlet pipe in turn. Whenever the liquid inlet pipe is at the depth required for sampling, the solution will enter one of the sampling cups. After the solution enters the sampling cup, the turntable continues to rotate, so that the remaining sampling cups move to the liquid inlet pipe. In this way, the solution of different depths can be stored in multiple sampling cups. When the solution in the sampling cup needs to be collected, the turntable is driven to rotate. The fixed plate slides upward, and when the turntable moves to the opening at the upper end of the sleeve, the personnel will take out multiple sampling cups from the placement slot to obtain solution samples of different depths. In addition, since the number of sampling cups is set to multiple, there is no need to take out the sampling cups frequently. After multi-point sampling, the sampling cups can be collected uniformly, which reduces the complexity and time cost of the operation and ensures the sampling progress. In addition, the cup cover in the initial state covers the upper end of the sampling cup. When the sampling cup moves to the liquid inlet pipe, the gear and the cup cover are driven to rotate. When the sampling cup has collected enough solution, the cup cover will cover the upper end of the sampling cup again, and under the action of the torsion spring, the cup cover will not be opened due to the movement of the sampling cup, further avoiding the splashing of the solution. When the solution flows into the sampling cup and needs to be taken out immediately, the sampling cup can be driven to move under the lifting plate, and the sampling cup is between the two clamping blocks at this time, and then the two clamping blocks are used to clamp the sampling cup, and then the clamped sampling cup is driven to move to the sleeve. The worker then removes the sampling cup and obtains the solution sample immediately. During this period, the turntable can still rotate and perform sampling, which will not affect the collection of solution by other sampling cups. Similarly, when the number of sampling cups is insufficient, the sampling cup can be moved to the top of the sleeve by using the clamping block, and the sampling cup containing the solution can be replaced. When the sampling cup is replaced, the other sampling cups can also perform sampling, and the replaced sampling cup is reset to the same position as the replaced sampling cup to continue sampling.

An electric push rod 14 is fixedly connected to one side of the upper end surface of the turntable 8, and the piston end of the electric push rod 14 is fixedly connected to one end of the rack 25.

One side of the upper end of the sleeve 3 is fixedly connected to a motor six 24, and the output end of the motor six 24 is fixedly connected to the upper end of the threaded rod three 11. The upper end of the clamping block 22 is threadedly connected to a bidirectional threaded rod 21, and both ends of the bidirectional threaded rod 21 are rotatably set on the lifting plate 15. One end of the lifting plate 15 is fixedly connected to a motor four 20, and the output end of the motor four 20 is fixedly connected to one end of the bidirectional threaded rod 21.

[0034] Specifically, when the existing reactor sampling device is used, the sampling tube is sunk into the solution inside the reactor by a traction rope, and the sampling tube is taken out of the reactor after it is filled with the solution. Although solutions at different depths can be sampled in this way, in some cases, in order to more comprehensively understand the situation of the solution inside the reactor, it is necessary to sample solutions at different depths for multiple times in succession. In order to achieve multiple sampling, the sampling tube needs to be removed from the reactor after completing one sampling work, and then the collected solution is discharged before the next sampling work can be carried out, which increases the complexity and time cost of the operation and affects the sampling progress. Therefore, in order to solve the above problems, when the present embodiment is in use, the motor three 18 can drive the turntable 8 to rotate, so that the openings of the sampling cups 12 at different positions are aligned with the liquid inlet pipe 28 in turn. Whenever the liquid inlet pipe 28 is at the depth required for sampling, the solution will enter one of the sampling cups 12. When the solution enters the sampling cup 12, the turntable 8 continues to rotate, so that the remaining sampling cups 12 move to the liquid inlet pipe 28. In this cycle, solutions of different depths can be stored in multiple sampling cups 12. When it is necessary to collect the solutions in the sampling cups 12, the motor five 23 drives the threaded rod two 10 to rotate, so that the fixing plate 17 can slide upward. When the turntable 8 moves to the opening at the upper end of the sleeve 3, the personnel will uniformly remove the multiple sampling cups 12 from the placement slot 9, so as to obtain solution samples of different depths. Moreover, since the number of sampling cups 12 is set to be multiple, it is not necessary to frequently take out the sampling cups 12, which reduces the complexity and time cost of the operation and ensures the sampling progress. Furthermore, since the solution in the sampling cup 12 may splash out during the rotation of the turntable 8, when the solution in the sampling cup 12 splashes out into another sampling cup 12, solutions of different depths will be mixed, thereby affecting the accuracy of sampling. Therefore, in order to avoid this situation, the cup cover 13 in the initial state covers the upper end of the sampling cup 12. When the sampling cup 12 moves to the liquid inlet pipe 28, the electric push rod 14 drives the rack 25 to move, so that the gear 26 and the cup cover 13 rotate, and the cup cover 13 When the sampling cup 12 is away from the top, the collection work can be carried out normally. When enough solution is collected in the sampling cup 12, the rack 25 is away from the gear 26, and the cup cover 13 covers the upper end of the sampling cup 12 again. Moreover, under the action of the torsion spring 27, the cup cover 13 will not be opened due to the movement of the sampling cup 12, thereby further avoiding the splashing of the solution. In addition, since the magnetic block 16 and the magnetic sheet 31 are mutually attracted, the sampling cup 12 will not be deviated due to the contact between the rack 25 and the gear 26. In some cases, in order to speed up the sampling progress, it is necessary to take out a sampling cup 12 from the sleeve 3 immediately after it collects the solution. If the turntable 8 is driven to rise, the other sampling cups 12 will not be able to perform sampling work normally. In addition, when there are too many sampling points, the number of sampling cups 12 may be insufficient, and the sampling cups 12 on the turntable 8 need to be replaced. If the turntable 8 is driven to rise to the end of the sleeve 3 and then the sampling cups 12 on the turntable 8 are replaced, the other sampling cups 12 will not be able to perform sampling work normally. Therefore, in order to solve this problem, when the solution flows into the sampling cup 12 and needs to be taken out immediately, the sampling cup 12 can be driven to move under the lifting plate 15, and the sampling cup 12 is between the two clamping blocks 22 at this time, and then the motor six 24 is used to drive the threaded rod three 11 to rotate, so that the clamping block 22 descends, and then the motor four 20 is used to drive the The two-way threaded rod 21 is driven to rotate, so that the two clamping blocks 22 are close to each other to clamp the sampling cup 12, and then the lifting plate 15 is driven to rise, so that the sampling cup 12 can be removed from the placement groove 9, and the sampling cup 12 can be moved to the upper end of the sleeve 3, and then the worker can remove the sampling cup 12 to immediately obtain the solution sample, and during this period, the turntable 8 can still rotate and perform sampling work, which will not affect the collection of solution by the remaining sampling cups 12. Similarly, when the number of sampling cups 12 is insufficient, the clamping block 22 can also be used to move the sampling cup 12 to the top of the sleeve 3, and the sampling cup 12 filled with the solution can be replaced, and when the sampling cup 12 is replaced, the remaining sampling cups 12 can also perform sampling work, and the replaced sampling cup 12 is reset to the same position as the previous sampling cup 12, and the sampling work can continue, and because the magnetic suction block 16 can be adsorbed by the magnetic suction sheet 31, the sampling cup 12 can be accurately reset to the placement groove 9.

[0035] Working principle: The mounting base 1 is installed on the top of the reactor by bolting, and the sleeve 3 is aligned with the opening on the top of the reactor, and then the motor 4 is used to drive the threaded rod 5 to rotate, so that the connecting rod 7 moves downward, so that the sleeve 3 can be extended into the solution inside the reactor, and the solution does not exceed the top of the sleeve 3. When the liquid inlet pipe 28 is at the depth required for sampling, the solenoid valve 29 on the liquid inlet pipe 28 is opened, and the solution flows into the sampling cup 12 along the liquid inlet pipe 28, so that the solution samples of different depths can be obtained by adjusting the sampling height, so as to have a more comprehensive understanding of the situation of the solution inside the reactor. The turntable 8 can be driven to rotate so that the openings of the sampling cups 12 at different positions are aligned with the liquid inlet pipe 28 in turn. Whenever the liquid inlet pipe 28 is at the depth required for sampling, the solution will enter one of the sampling cups 12. After the solution enters the sampling cup 12, the turntable 8 continues to rotate to move the remaining sampling cups 12 to the liquid inlet pipe 28. In this way, solutions of different depths can be stored in multiple sampling cups 12. When it is necessary to collect the solutions in the sampling cups 12, the motor 5 23 is used to drive the threaded rod 2 10 to rotate, so that the fixing plate 17 can slide upward. When the turntable 8 moves to the opening at the upper end of the sleeve 3, personnel can put multiple sampling cups 12 into the sampler 12. By uniformly taking out the samples of the solutions at different depths from the placement slot 9, solution samples at different depths can be obtained. Moreover, since the number of the sampling cups 12 is set to be multiple, there is no need to frequently take out the sampling cups 12, which reduces the complexity and time cost of the operation and ensures the sampling progress. Moreover, since the solution in the sampling cup 12 may splash out during the rotation of the turntable 8, when the solution in the sampling cup 12 splashes out into another sampling cup 12, solutions at different depths will be mixed, thereby affecting the accuracy of the sampling. Therefore, in order to avoid this situation, the cup cover 13 in the initial state covers the upper end of the sampling cup 12. When the sampling cup 12 is in the state of being removed, the sample will be removed from the cup 12. When it moves to the liquid inlet pipe 28, the electric push rod 14 drives the rack 25 to move, so that the gear 26 and the cup cover 13 rotate, and the cup cover 13 is away from the top of the sampling cup 12, and the collection work can be carried out normally. When enough solution is collected inside the sampling cup 12, the rack 25 is away from the gear 26, and the cup cover 13 covers the upper end of the sampling cup 12 again, and under the action of the torsion spring 27, the cup cover 13 will not be opened due to the movement of the sampling cup 12, further avoiding the splashing of the solution, and because the magnetic suction block 16 and the magnetic suction sheet 31 are mutually attracted, the sampling cup 12 will not be deviated due to the contact between the rack 25 and the gear 26;In some cases, in order to speed up the sampling progress, it is necessary to take out a sampling cup 12 from the sleeve 3 immediately after it collects the solution. If the turntable 8 is driven to rise, the other sampling cups 12 will not be able to perform sampling work normally. In addition, when there are too many sampling points, the number of sampling cups 12 may be insufficient, and the sampling cups 12 on the turntable 8 need to be replaced. If the turntable 8 is driven to rise to the end of the sleeve 3 and then the sampling cups 12 on the turntable 8 are replaced, the other sampling cups 12 will not be able to perform sampling work normally. Therefore, in order to solve this problem, when the solution flows into the sampling cup 12 and needs to be taken out immediately, the sampling cup 12 can be driven to move under the lifting plate 15, and the sampling cup 12 is between the two clamping blocks 22 at this time, and then the motor six 24 is used to drive the threaded rod three 11 to rotate, so that the clamping block 22 descends, and then the motor four 20 is used to drive the The two-way threaded rod 21 is rotated to make the two clamping blocks 22 approach each other to clamp the sampling cup 12, and then the lifting plate 15 is driven to rise, so that the sampling cup 12 can be removed from the placement slot 9, and the sampling cup 12 can be moved to the upper end of the sleeve 3, and then the worker can remove the sampling cup 12 to immediately obtain the solution sample. In addition, during this period, the turntable 8 can still rotate and perform sampling work, which will not affect the collection of solution by the remaining sampling cups 12. Similarly, when the number of sampling cups 12 is insufficient, the clamping block 22 can also be used to move the sampling cup 12 to the top of the sleeve 3, and the sampling cup 12 containing the solution can be replaced. In addition, when the sampling cup 12 is replaced, the remaining sampling cups 12 can also perform sampling work. The replaced sampling cup 12 is reset to the same position as the previous sampling cup 12, and the sampling work can continue. In addition, since the magnetic suction block 16 can be adsorbed with the magnetic suction sheet 31, the sampling cup 12 can be accurately reset to the placement slot 9. ;
