Description

Technical Field

[0001] The utility model belongs to the technical field of fine chemical industry, and in particular relates to a sampling device for a chemical reaction kettle. Background Art

[0002] The reactor is a container commonly used for chemical reactions in the chemical industry. It can realize the heating, evaporation, cooling and low-speed mixing functions required by the process. It is equipped with a stirring paddle for stirring and accelerating the reaction. The reaction solution and solid reactants are mixed and reacted in the reactor under the action of the stirring paddle.

[0003] When configuring a product, it is necessary to sample and test the reaction progress and product quality in the reactor during the product manufacturing process. In the prior art, a sampling tube is usually set on one side of the reactor body. When sampling is required, the valve on the sampling tube is opened to perform sampling. Although this sampling method can also achieve material sampling, it can only test the materials at the same height in the reactor during sampling, which makes it inconvenient to know the reaction progress and quality of materials at other heights. In view of this, the present invention is proposed. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a sampling device for a chemical reactor that can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a sampling device for a chemical reactor, including a sampling barrel, which is arranged on one side of the reactor body, and also includes: a connecting pipe, which is equidistantly connected to one side of the sampling barrel, and a plurality of sampling ports for use with the connecting pipes are opened on the side of the reactor body close to the sampling barrel, and an electromagnetic valve is installed at the sampling port of the reactor body, and the ends of the plurality of connecting pipes away from the sampling barrel are respectively connected to the electromagnetic valves at the same height; a placing cylinder, which is threadedly connected to the opening at the lower end of the sampling barrel.

[0006] In order to facilitate quantitative sampling of materials, the containing cylinder is further configured to be transparent and has scale lines on it.

[0007] Furthermore, a suction tube is connected to the upper end of one side of the sampling cylinder, and a sealing rubber ring used in conjunction with the containing cylinder is fixedly connected to the opening of the lower end of the sampling cylinder.

[0008] In order to prevent the accuracy of the next sampling test from being affected by the solution attached to the inside of the sampling cylinder, connecting tube and holding cylinder, the upper end of the sampling cylinder is fixedly connected to a drive motor, and a stirring rod is provided in the sampling cylinder, and the upper end of the stirring rod is fixedly connected to the output end of the drive motor.

[0009] In order to further improve the cleaning effect, the connecting pipe is a connecting hose, a support plate is fixedly connected to the upper side of the reactor body close to the sampling tube, the driving motor is a dual-axis motor, and a reciprocating screw is fixedly connected to the other output end of the driving motor. The reciprocating screw is threadedly connected to the support plate, and two guide rods are symmetrically fixedly connected to the upper end of the sampling tube, and the guide rods are slidably connected to the support plate.

[0010] In order to facilitate knowing whether the sampling cylinder and the connecting tube are clean, further, the sampling cylinder and the connecting tube are both transparent.

[0011] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the existing technology: the utility model uses a sampling tube, multiple connecting tubes, multiple electromagnetic valves and a holding tube and other components in combination. When sampling and testing materials in a chemical reactor, compared with the existing technology that can only sample and test materials at the same height, the utility model can sample and test materials at different heights in the chemical reactor, so as to know the reaction progress of materials at different heights in the chemical reactor and whether the reaction is uniform, thereby further improving the subsequent detection accuracy.

[0012] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] Example 1:

[0021] Reference Figures 1-4 A sampling device for a chemical reactor includes a sampling cylinder 1, which is arranged on one side of a reactor body 3, and also includes: a connecting pipe 101, which is equidistantly connected to one side of the sampling cylinder 1, and a plurality of sampling ports 301 for use with the connecting pipe 101 are opened on the side of the reactor body 3 close to the sampling cylinder 1. An electromagnetic valve 102 is installed at the sampling port 301 of the reactor body 3, and the ends of the plurality of connecting pipes 101 away from the sampling cylinder 1 are respectively connected to the electromagnetic valves 102 at the same height; a receiving cylinder 103 is threadedly connected to the opening at the lower end of the sampling cylinder 1.

[0022] During the process of adding chemical raw materials into the reactor body 3 for reaction configuration, in order to monitor the reaction progress and product quality of the materials in the reactor body 3, it is necessary to sample and analyze the materials in the reactor body 3. At this time, one of the electromagnetic valves 102 can be opened, and then the materials in the reactor body 3 at the height of the electromagnetic valve 102 will flow into the connecting pipe 101 through the sampling port 301, and then flow into the sampling cylinder 1 through the connecting pipe 101, and finally fall into the holding cylinder 103. When a certain amount of material is stored in the holding cylinder 103, the electromagnetic valve 102 can be closed, sampling is stopped, and a period of time is waited. When the attached material in the sampling cylinder 1 no longer drips, the holding cylinder 103 can be removed and the material inside it can be tested.

[0023] Then, a new holding cylinder 103 is connected to the lower end of the sampling cylinder 1, and then another electromagnetic valve 102 is opened. Then, the material at the same height as the electromagnetic valve 102 in the reactor body 3 can be sampled. By repeating this process, the material at different heights in the reactor body 3 can be sampled and tested, so as to know the reaction progress of the materials at different heights in the reactor body 3 and whether the reaction is uniform.

[0024] Example 2:

[0025] Reference Figures 1-4 A sampling device for a chemical reactor is basically the same as that of Example 1, but further features that: a holding tube 103 is transparent and has scale lines 104 on it. When one of the electromagnetic valves 102 is opened for sampling, the staff can check the sampling amount according to the scale lines 104, so as to accurately control the sampling amount and avoid over-sampling or under-sampling.

[0026] The upper end of one side of the sampling tube 1 is connected to a suction tube 105, and the opening at the lower end of the sampling tube 1 is fixedly connected to a sealing rubber ring 106 used in conjunction with the holding tube 103. Through the setting of the suction tube 105, when the reaction solution in the reactor body 3 is relatively thick, in order to speed up the sampling efficiency, the suction tube 105 can be connected to the external negative pressure component, so that the sampling tube 1 can be subjected to negative pressure treatment, thereby speeding up the sampling efficiency of the relatively thick reaction solution. Through the setting of the sealing rubber ring 106, a sealing effect can be played between the holding tube 103 and the sampling tube 1, thereby ensuring the negative pressure effect in the sampling tube 1.

[0027] Example 3:

[0028] Reference Figures 1-4 A sampling device for a chemical reactor is basically the same as Example 2, and furthermore: the upper end of the sampling cylinder 1 is fixedly connected to the driving motor 2, and a stirring rod 201 is provided in the sampling cylinder 1, and the upper end of the stirring rod 201 is fixedly connected to the output end of the driving motor 2.

[0029] The connecting pipe 101 is a connecting hose. A support plate 204 is fixedly connected to the upper side of the reactor body 3 close to the sampling cylinder 1. The driving motor 2 is a dual-axis motor. A reciprocating screw 202 is fixedly connected to the other output end of the driving motor 2. The reciprocating screw 202 is threadedly connected to the support plate 204. Two guide rods 203 are symmetrically fixedly connected to the upper end of the sampling cylinder 1, and the guide rods 203 are slidably connected to the support plate 204.

[0030] The sampling tube 1 and the connecting tube 101 are both transparent.

[0031] When the sampling of the reaction solution in the reactor body 3 is completed, the staff will connect the holding cylinder 103 to the sampling cylinder 1, and then a certain amount of cleaning liquid can be transported into the sampling cylinder 1 through the suction tube 105, and then the driving motor 2 can be started. The driving motor 2 will drive the stirring rod 201 and the reciprocating screw rod 202 to rotate at the same time. When the stirring rod 201 rotates, the cleaning liquid in the sampling cylinder 1 can be stirred, so that the solution attached to the sampling cylinder 1, the connecting tube 101 and the holding cylinder 103 can be removed. When the reciprocating screw rod 202 rotates, the sampling cylinder 1 can be driven to move back and forth up and down with the cooperation of the guide rod 203 and the support plate 204, thereby driving the cleaning liquid in the sampling cylinder 1 to shake up and down, so that the cleaning liquid can flow in the sampling cylinder 1, the connecting tube 101 and the holding cylinder 103, thereby further improving the cleaning efficiency of the attached solution and effectively improving the stripping of the solution. After the cleaning of the cleaning tube 1, the cleaning agent 101 is removed, and the cleaning liquid is discharged. Then the cleaning tube 103 is installed on the cleaning tube 1, and clean water is injected into the cleaning tube 1 through the suction tube 105. Then, the cleaning operation is repeated to clean the cleaning tube 1 more thoroughly, ensuring the cleanliness of the interior of the cleaning tube 1, the cleaning tube 101 and the cleaning tube 103. Finally, the interior of the cleaning tube 1, the cleaning tube 101 and the cleaning tube 103 are dried to avoid affecting the accuracy of the next sampling test due to the adhesion of the solution to the interior of the cleaning tube 1, the cleaning tube 101 and the cleaning tube 103.

[0032] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
