[0001] The utility model relates to the technical field of reaction kettles, in particular to a reaction kettle with a sampling structure. Background Art

[0002] A reaction kettle is a device widely used in the fields of chemistry, pharmacy, food, petroleum, chemical industry, etc., mainly used for carrying out chemical reactions, mixing, dissolving, crystallization, separation and other operations. During the working process of the reaction kettle, sampling is required. A reaction kettle with a sampling structure is convenient for technicians to perform sampling. Such a reaction kettle can monitor the reaction process and facilitate the adjustment of reactants;

[0003] In the patent document with the publication number of CN220835416U, it discloses a glyphosate aqueous agent production and mixing device with a monitoring function, including a mixing cylinder. The mixing cylinder stirs the materials, and it is provided with a sampling device. The sampling device is used to sample the reactants. The sampling device includes a sampling tube. The lower part of the sampling tube extends into the mixing cylinder. In the mixing cylinder, connection holes are opened on the side wall of the sampling tube. A connecting rod and a sampling bottle are also provided. When sampling is required, the reaction liquid in the mixing cylinder is sampled by connecting the sampling bottle with the sampling tube;

[0004] However, there are usually differences in aspects such as the liquid temperature, concentration and mixing degree of the reaction liquid at different heights. It can be known from the specification and its attached drawings of the above patent document that since the sampling tube of this device is fixedly arranged, it can only extract the reaction liquid at the same height in the mixing cylinder, so that technicians can only investigate the situation of the reaction liquid at the height where the sampling tube is located, that is, the height of the sampled reaction liquid is fixedly arranged. Therefore, the sampling function of this device has limitations. Therefore, it is necessary to make improvements to the existing technology for the above problems. Content of the Utility Model

[0005] Since the existing reaction kettle can only sample the reaction liquid at the same height when sampling the reaction liquid, it is inconvenient to sample the reaction liquid at different liquid levels. In order to improve the above problems, this application provides a reaction kettle with a sampling structure.

[0006] The technical solution adopted by the reaction kettle with a sampling structure provided by the utility model is as follows:

[0007] A reaction kettle with a sampling structure includes a reaction chamber, a water pump, and a lower sampling component. The reaction chamber is provided with a sampling port. The water pump is connected to the side wall of the reaction chamber. The lower sampling component includes a lower wheel and a sliding rod. The lower wheel is rotatably connected to the upper end of the sliding rod. The axial direction of the lower wheel is perpendicular to the axial direction of the sampling port. An abutting groove is recessed and annularly arranged on the circumferential wall of the lower wheel. The sliding rod is slidably connected to the side wall of the reaction chamber. The lower wheel is slidably arranged in a lockable manner back and forth towards the sampling port.

[0008] Among them, the downsampling component further includes a Y-shaped joint, the Y-shaped joint is connected to the upper end of the sliding rod, and the lower wheel is rotatably connected to the Y-shaped joint.

A vertical threaded hole is provided in the receiving portion. The lead screw is threadedly connected to the threaded hole. A connecting plate is fixedly provided at the lower end of the sliding rod. A rotating hole is provided in the connecting plate. Two groups of limiting portions are concavely and convexly provided on the circumferential wall of the lead screw. The rotating hole is rotatably connected to the lead screw between the two groups of limiting portions.

[0011] Among them, the receiving portion is further provided with a sliding hole, and the sliding rod is slidably connected to the sliding hole.

[0012] Among them, an upsampling component is further included, and the upsampling component and the downsampling component are symmetrically arranged with respect to the horizontal plane where the axis of the sampling port is located.

[0013] Among them, the downsampling component further includes a revolution counter. The revolution counter is connected to the outer side surface of the Y-shaped joint. The lower wheel is connected with multiple groups of induction points for sensing the number of turns. An induction block for sensing the induction points is connected to the surface of the Y-shaped joint facing the induction points. The induction block is electrically connected to the revolution counter.

[0014] Among them, the induction points are provided in one group or multiple groups. When provided in multiple groups, the induction points are connected to the side surface of the lower wheel in a circumferential array.

[0016] Among them, a sampling door for opening and closing the sampling port is further included. The sampling door is rotatably connected to the outer surface of the side wall of the reaction chamber. The sampling door is rotatably arranged back and forth towards the sampling port.

[0017] The beneficial effects of the present utility model are as follows: When sampling is required, the pipe wall of the water suction pipe of the water pump is abutted against the abutting groove, and the lower wheel is driven to rotate. At this time, the driving length of the water suction pipe can be calculated through the number of rotations of the lower wheel. When starting the calculation, the water suction port of the water suction pipe faces the sampling port or makes the water suction port of the water suction pipe contact the liquid level of the reaction liquid, and then the lower wheel is driven to rotate, so that the water suction port of the water suction pipe enters the reaction chamber from the sampling port or starts to enter below the liquid level of the reaction liquid. By calculating the number of rotations of the lower wheel, the depth of the water suction pipe entering the reaction chamber or the depth of entering the reaction liquid can be known. At the same time, by driving the rotation of the lower wheel, the water suction pipe can enter the reaction liquid at different depths, that is, the reaction liquid at different heights, sample the reaction liquid at different heights, and at the same time, its height can also be known.

Detailed implementation mode

[0027] The following will further illustrate the present utility model in conjunction with the attached Figures 1-8 drawings and embodiments.

[0028] This embodiment discloses a reactor with a sampling structure.

[0029] Referring to Figures 1-8 , a reactor with a sampling structure includes a reaction chamber 11, a water pump 13, and a lower sampling assembly 31. A sampling port 12 is provided on the side wall of the reaction chamber 11. The water pump 13 is connected to the side wall of the reaction chamber 11. The water pump 13 is provided with a water suction pipe 44 and a water outlet pipe 45. The lower sampling assembly 31 includes a lower wheel 33 and a sliding rod 35. The lower wheel 33 is rotatably connected to the upper end of the sliding rod 35. The axial direction of the lower wheel 33 is perpendicular to the axial direction of the sampling port 12, that is, the axial direction of the lower wheel 33 is the X direction. An annular abutting groove 34 is recessed on the circumferential wall of the lower wheel 33 for receiving the water suction pipe 44. The sliding rod 35 is vertically slidably connected to the side wall of the reaction chamber 11, and the vertical direction is the Z direction. The lower wheel 33 is slidably arranged in a lockable manner towards the sampling port 12, so that the lower wheel 33 can be driven away from the sampling port 12. The water pump 13 is connected to the reaction chamber 11 and is located on one side of the sampling port 12. When sampling is required, the pipe wall of the water suction pipe 44 of the water pump 13 is abutted in the abutting groove 34, and the lower wheel 33 is driven to rotate. At this time, the driving length of the water suction pipe 44 can be calculated by the number of rotations of the lower wheel 33. When starting to calculate, the water suction port of the water suction pipe 44 faces the sampling port 12 or the water suction port of the water suction pipe 44 is in contact with the liquid level of the reaction solution, and then the lower wheel 33 is driven to rotate, so that the water suction port of the water suction pipe 44 enters the reaction chamber 11 from the sampling port 12 or starts to enter below the liquid level of the reaction solution. By calculating the number of rotations of the lower wheel 33, the depth of the water suction pipe 44 entering the reaction chamber 11 or the depth of entering the reaction solution can be known. At the same time, by driving the rotation of the lower wheel 33, the water suction pipe 44 can enter the reaction solution at different depths, that is, the reaction solution at different heights, sample the reaction solution at different heights, and at the same time, its height can also be known.

[0030] The reaction chamber 11 is provided with a reaction cavity, a discharge port 52, and a feed port 51. The reaction chamber 11 is also rotatably connected with an opening and closing cover 53 for opening and closing the feed port 51 at the feed port 51. The reaction raw materials are put into the reaction cavity through the feed port 51, and the stirring mechanism in the reaction chamber 11 stirs it. The prepared substance is then discharged from the discharge port 52. The discharge port 52 is communicated with the reaction cavity, and the feed port 51 is communicated with the reaction cavity.

[0031] A chassis 54 for receiving the reaction chamber 11 is further provided below the reaction chamber 11.

[0032] Further, the downsampling component 31 further includes a Y-shaped joint 36. The Y-shaped joint 36 is connected to the upper end of the sliding rod 35, and the lower wheel 33 is rotatably connected to the Y-shaped joint 36. By providing the Y-shaped joint 36, the stability of the rotation of the lower wheel 33 is improved, thereby improving the stability of the movement of the water extraction pipe 44.

[0033] When the water extraction pipe 44 abuts against the abutment groove 34, since there is a risk of relative slippage between the abutment groove 34 of the lower wheel 33 and the water extraction pipe 44 when driving the water extraction pipe 44 to move by rotating the lower wheel 33, the accuracy of the driving length of the water extraction pipe 44 during driving is reduced, thereby affecting the calculation of the depth of the reaction liquid where the water extraction port of the water extraction pipe 44 is located. To solve the above problems, a rubber member is connected to the groove surface of the abutment groove 34 in this embodiment. The rubber member is annularly arranged on the abutment groove 34. By providing the rubber member, the driving friction between the rubber member and the water extraction pipe 44 is increased, thereby reducing the possibility of slippage between the abutment groove 34 and the water extraction pipe 44, improving the accuracy of the driving length of the water extraction pipe 44, and further improving the calculation depth of the depth of the reaction liquid.

[0034] To realize the adjustment of the height of the lower wheel 33, this embodiment provides an adjustment method. The downsampling component 31 of this embodiment further includes a lead screw 32. A receiving portion 14 is protrudingly provided on the side wall of the reaction chamber 11. A vertical threaded hole 15 is provided in the receiving portion 14. The lead screw 32 is threadedly connected to the threaded hole 15. A connecting plate 39 is fixedly provided at the lower end of the sliding rod 35. A rotating hole 38 is provided in the connecting plate 39. Two groups of limiting portions 50 are provided with concave and convex protrusions on the circumferential wall of the lead screw 32. The two groups of limiting portions 50 are arranged at intervals along the Z direction. The rotating hole 38 is rotatably connected between the two groups of limiting portions 50. The limiting portions 50 enable the lead screw 32 to drive the connecting plate 39 to slide. By rotating the lead screw 32, the lead screw 32 can slide upward relative to the receiving portion 14 through the threaded hole 15, thereby driving the sliding rod 35 to slide through the limit, and further driving the lower wheel 33 to slide upward, so that the lower wheel 33 is arranged corresponding to the sampling port 12.

[0035] To further improve the stability of the sliding of the sliding rod 35, a sliding hole 40 with an axial direction of Z is further provided in the receiving portion 14 of this embodiment. The sliding rod 35 is slidably connected to the sliding hole 40. The sliding of the sliding rod 35 in the sliding hole 40 limits the sliding rod 35, thereby reducing the force received by the sliding rod 35 and improving the stability of the sliding of the sliding rod 35.

[0036] When the downsampling component 31 abuts against the water extraction pipe 44, the water extraction pipe 44 may slip with the lower wheel 33 due to insufficient abutting force. To solve the above problem, this embodiment further includes an upsampling component 48. The horizontal plane 41 where the axis of the sampling port 12 is located is parallel to the ground where the equipment is located. The upsampling component 48 and the downsampling component 31 are symmetrically arranged with respect to the horizontal plane 41. The upsampling component 48 abuts against the upper side of the water extraction pipe 44 on the upper side of the horizontal plane 41, and the downsampling component 31 abuts against the lower side of the water extraction pipe 44 on the lower side of the horizontal plane 41, so that the upper and lower sides of the water extraction pipe 44 are respectively abutted by the upsampling component 48 and the downsampling component 31, improving the degree of the limiting effect on the water extraction pipe 44 and further reducing the possibility of the water extraction pipe 44 slipping;

[0037] When driving the water extraction pipe 44 to slide downward toward the lower side of the reaction liquid surface, the lower wheel 33 will rotate accordingly. By calculating the number of rotation turns of the lower wheel 33, the depth of the water extraction pipe 44 is calculated, improving the smoothness of the sliding of the water extraction pipe 44.

[0038] To facilitate the calculation of the driving distance of the water extraction pipe 44 by technicians, the downsampling component 31 of this embodiment further includes a revolution counter 42. The revolution counter 42 is connected to the outer side surface of the Y-shaped joint 36. The lower wheel 33 is connected with an induction point 43 for sensing the number of rotation turns of the lower wheel 33. One side of the Y-shaped joint 36 facing the induction point 43 is connected with an induction block 49. The induction block 49 is electrically connected to the revolution counter 42. The induction block 49 is used to sense with the induction point 43. The number of rotation turns of the lower wheel 33 is calculated by the revolution counter 42. When the technician drives the water extraction port of the water extraction pipe 44 to contact the liquid surface of the reaction liquid, the revolution counter 42 is reset, and the water extraction pipe 44 is continuously driven to slide downward. The number of rotation turns of the lower wheel 33 is calculated by the revolution counter 42, and then the depth of the reaction liquid where the water extraction pipe 44 is located is deduced.

[0039] It should be further noted that the technician can either directly drive the water extraction pipe 44 to slide downward or drive the rotation of the lower wheel 33, so that the water extraction pipe 44 is driven by the lower wheel 33 and then driven to slide downward.

[0040] To further improve the accuracy of the revolution counter 42 for counting turns, the induction points 43 of this embodiment are provided in one group or multiple groups. When provided in multiple groups, the induction points 43 are connected to the side surface of the lower wheel 33 in a circumferential array. Through the above settings, the accuracy of the revolution counter 42 when counting turns is improved.

[0041] In the foregoing, whether the water extraction pipe 44 contacts the liquid level of the reaction liquid is identified by a technician. This identification method has a risk of generating large errors. To solve the above problems, a water immersion sensor 46 for sensing whether the water extraction port contacts the liquid level of the reaction liquid is connected to the water extraction port of the water extraction pipe 44 in this embodiment. When the water immersion sensor 46 sends a signal indicating contact with the liquid level, the revolution counter 42 starts counting the number of revolutions of the lower wheel 33, and converts it into the depth at which the water extraction port of the water extraction pipe 44 is located, improving the convenience for the technician to identify whether the water extraction pipe 44 contacts the liquid level of the reaction liquid.

[0042] To improve the sealing degree of the reaction chamber 11, this embodiment further includes a sampling door 47 for opening and closing the sampling port 12. The sampling door 47 is rotatably connected to the outside of the reaction chamber 11, and the sampling door 47 is arranged to rotate back and forth towards the sampling port 12. When sampling is not required, the sampling door 47 is closed, thereby closing the sampling port 12 and also preventing the reaction liquid in the reaction chamber 11 from splashing out.

[0043] The above are all the preferred embodiments of the present invention, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
