[0026] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0027] Embodiment 1

[0028] Please refer to Figures 1 to 4 , in this embodiment, a simple sampling type distillation head is provided, which includes a distillation head body 1. A side pipe 2 is provided on one side of the upper part of the distillation head body 1. The bottom of the side pipe 2 is connected to a branch pipe 3, and a first receiving bottle 5 is sleeved at the lower end of the branch pipe 3. The first receiving bottle 5 is detachably connected to the branch pipe 3 and can be removed after being filled with materials. A three-way stop valve A 7 is installed on the side pipe 2. At the same time, a discharge pipe 4 is also provided on the lower part of the distillation head body 1 on the same side as the side pipe 2. The materials generated after distillation will flow out from the discharge pipe 4. The end of the discharge pipe 4 is located inside the branch pipe 3 and directly above the first receiving bottle 5, so that the discharged materials can enter the first receiving bottle 5. Among them, the distillation head body 1 is respectively communicated with the branch pipe 3 through the side pipe 2 and the discharge pipe 4;

[0029] Moreover, a three-way stop valve B8 and a three-way stop valve C9 are also provided on the discharge pipe 4. The structures of the two are the same. A sampling pipe 12 is installed on one of their outlets. Moreover, a second receiving bottle 6 is provided on one of the sampling pipes 12, that is, receiving of materials can also be achieved from the sampling pipe 12. In this way, after the first receiving bottle 5 is filled with materials, without stopping the operation, materials can be directly received from one of the sampling pipes 12, enabling continuous operation. Moreover, since there are two sampling pipes 12, it will not affect sampling, achieving the effect of convenient sampling;

[0030] A vacuum pipe 10 is also connected between the three-way stop valve A7 and the distillation head body 1 on the side pipe 2. The vacuum pipe 10 serves to evacuate the air, and an exhaust pipe 11 is also installed on the side outlet of the three-way stop valve A7;

[0031] It should be noted that the structures of the three-way stop valve A7, the three-way stop valve B8, and the three-way stop valve C9 are the same. One end of the valve body of any one rotary valve is port A, and the other end is port B. Port A and port B are on the same pipeline, and port C is located on the side of the valve body. The mutual connection between the three ports is achieved by manually controlling the valve core (in this application, in combination with the attached drawings, the port at the upper end of the stop valve is taken as A, and the port at the lower side is taken as B);

[0032] Based on this, in this embodiment, port A, port B of the three-way stop valve A7 are connected to the side pipe 2, and the side port C is installed on the exhaust pipe 11;

[0033] For the three-way stop valve B8 and the three-way stop valve C9, port A, port B are connected to the discharge pipe 4, and sampling pipes 12 are installed on their side ports C;

[0034] During use, usually during discharging, one of the positions at the sampling pipe 12 of the three-way stop valve B8 and the end of the discharge pipe 4 serves as the material collection port, that is, one of the first receiving bottle 5 and the second receiving bottle 6 works first. Taking the first receiving bottle 5 as an example for receiving materials;

[0035] After the distillation head starts to discharge, port A and port B of the three-way stop valve C9 and the three-way stop valve B8 are connected, making the discharge pipe 4 a passage, and the materials will flow out from the end of the discharge pipe 4 and then be collected by the first receiving bottle 5;

[0036] When sampling is required, control the three-way stop valve C9, rotate the valve to open port C, and the materials will flow out through the sampling pipe 12 to achieve the sampling operation;

[0037] After the sampling is completed, if the first material receiving bottle 5 is full of materials, the material receiving bottle is switched, the port C of the three-way stop valve C9 is closed, and the port C of the three-way stop valve B8 is opened, so that the material can enter the second material receiving bottle 6 to continue receiving materials. At this time, the port A is communicated with the port C, and the port B is closed;

[0038] The purpose of sampling is to detect the purity of the material. However, it takes a certain amount of time for the test results to come out. Once the test results meet the requirements, during the period from the sampling time to the time when the test results come out, if the material continues to flow out from the end of the discharge pipe 4 and is collected by the first material receiving bottle 5, it will cause material loss. Therefore, after sampling, it is collected at the second material receiving bottle 6. If the sampling result is qualified, the material is continuously collected. If the sampling result does not meet the requirements, re-sampling is required. After the re-sampling is completed, the collection is switched to the first material receiving bottle 5. At this time, the first material receiving bottle 5 at the end of the discharge pipe 4 has been replaced (after the first sampling is completed, when the second material receiving bottle 6 receives materials, by rotating the control three-way stop valve A7, the vacuum in the first material receiving bottle 5 is discharged through the exhaust pipe 11, the sampling bottle is removed, and an empty bottle is replaced for standby. At this time, the port A in the three-way stop valve A7 is not connected);

[0039] Through the above design, the material can be effectively collected, the material loss can be reduced, and a relatively accurate data can be obtained for the calculation of the yield in the small-scale experiment. At the same time, when collecting the effective material, both the first material receiving bottle 5 and the second material receiving bottle 6 are the material collection places. When one bottle is full, it can be immediately switched to the other bottle for collection, which is very convenient.

[0040] The utility model can realize on-line sampling at any time and timely collect the material after sampling. At the same time, there are two receiving ports. When one bottle is full of materials, it can be quickly switched to the other receiving bottle for receiving. The operation is simple, the sampling is convenient, and at the same time, the material can be effectively collected, the material loss can be reduced, and the material can be collected by the double receiving ports.

[0048] Port A and port B in the three-way stop valve A7 are connected, and its port C is not connected;

[0049] When sampling, place the sampling bottle at the sampling pipe 12. Keep the three-way stop valve C9 and the three-way stop valve A7 as they are. Rotate the three-way stop valve B8 to make port A and port C in the three-way stop valve B8 communicate. At this time, port B is not connected. After the sampling bottle receives a certain amount of material, rotate the three-way stop valve B8 to make port B and port C communicate. At this time, port A is not connected. At the same time, rotate the three-way stop valve A7 to make its port B and port C communicate, and keep the three-way stop valve C9 unchanged. Exhaust the vacuum in the sampling bottle through the exhaust pipe 11. After the vacuum is exhausted, remove the sampling bottle, and rotate the three-way stop valve B8 and the three-way stop valve A7 to make them in the initial state of receiving the material.
