Description

Technical Field

[0001] This utility model relates to the field of sample sampling device technology, and in particular to a sample sampling device for the preparation of di-tert-butyl peroxide. Background Technology

[0002] Di-tert-butyl peroxide (DTBP) is a highly efficient and multifunctional chemical. As an organic peroxide, it is mainly used in the chemical and rubber industries. It serves as a polymerization initiator in the production of polyethylene and polypropylene, a crosslinking agent to improve the properties of silicone rubber and polyester, and a vulcanizing agent to enhance the tensile strength and compression resistance of rubber products. In addition, it is used in grease bleaching, diesel additives, and transformer pour point depressants.

[0003] When the peroxide production process in the reactor is nearing completion, the produced peroxide needs to be inspected. Therefore, an automatic sampling device is required to sample the produced peroxide. However, traditional sampling devices can usually only sample samples at a single depth at a time and cannot sample samples at multiple depths simultaneously. Based on this, this utility model is proposed. Utility Model Content

[0015] 1. The sample sampling device for the preparation of di-tert-butyl peroxide, by setting a falling rod and multiple sliding blocks, can preset the sampling depth and simultaneously sample samples at different depths at one time, making the sampling data more accurate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1: Refer to Figures 1-5 A sample collection device for the preparation of di-tert-butyl peroxide includes a falling rod 1, and further includes: multiple sliding blocks 4 slidably connected inside the falling rod 1, and a cover plate 41 rotatably connected to the sliding blocks 4; a collection cylinder 2 is installed on the sliding blocks 4; a synchronization plate 3 is slidably connected inside the falling rod 1; a first connecting rod 42 is rotatably connected to the cover plate 41, a second connecting rod 43 is rotatably connected to the first connecting rod 42; a first sliding groove 12 is opened on the falling rod 1; the second connecting rod 43 is slidably connected to the first sliding groove 12; a third connecting rod 44 is rotatably connected to the second connecting rod 43; a second sliding groove 31 is opened on the synchronization plate 3; and the third connecting rod 44 is slidably connected inside the second sliding groove 31; when the synchronization plate 3 moves, all the cover plates 41 open or close simultaneously.

[0027] In this invention, by adjusting the position of the sliding block 4 in advance, the collection depth of the collection cylinder 2 can be changed. The user inserts the drop rod 1 into the reaction vessel, immersing multiple collection cylinders 2 in the peroxide. By moving the synchronization plate 3, all the cover plates 41 can be opened at a certain angle, thereby enabling the collection cylinders 2 to collect the peroxide. When the synchronization plate 3 is reset, the cover plates 41 are closed, and the user pulls the drop rod 1 out of the reaction vessel, thus completing the sampling of peroxide samples at different depths.

[0028] like Figure 2 As shown, when the synchronizing plate 3 slides to the right, it pulls the third connecting rod 44 to move synchronously. The third connecting rod 44 only slides in the second sliding groove 31 and does not rotate. This allows the third connecting rod 44 to pull the second connecting rod 43 to move as it follows the synchronizing plate 3. One end of the second connecting rod 43, after being pulled, slides upward in the first sliding groove 12. The other end of the second connecting rod 43 pulls the first connecting rod 42 to rotate and displace, thereby causing the cover plate 41 to flip within a certain range, so that the collecting cylinder 2 opens to complete the collection of peroxides.

[0029] Example 2: Refer to Figures 1-5 Similar to Embodiment 1, but further: multiple positioning holes 11 are provided inside the falling rod 1, and positioning bolts 5 are inserted into the positioning holes 11. Positioning bolts 5 are connected to positioning nuts 51 by threads. Positioning bolts 5 are inserted into sliding blocks 4. Locking blocks 21 are slidably connected inside the collecting cylinder 2. Compression springs 22 are connected between two locking blocks 21. A snap-fit ​​groove 45 is provided inside the sliding block 4. When the locking block 21 is snapped into the snap-fit ​​groove 45, the collecting cylinder 2 is fixed. A rotating handle 32 is rotatably connected to the falling rod 1. The rotating handle 32 is connected to the synchronization plate 3 by threads. Multiple sliding rods 13 are fixedly connected inside the falling rod 1. The synchronization plate 3 is slidably connected to the sliding rods 13.

[0030] In this utility model, the positioning bolt 5 is inserted into the positioning hole 11 and onto the sliding block 4, thereby positioning and fixing the sliding block 4. The collecting tube 2 can be quickly fixed and removed from the sliding block 4 through the locking block 21. One end of the locking block 21 is provided with a bevel. When the user installs and fixes the collecting tube 2, the sliding block 4 is pressed against the bevel of the locking block 21 and moves towards the center by pressing the collecting tube 2. When the locking block 21 is fully engaged in the snap-fit ​​groove 45, the locking block 21 is snapped into the snap-fit ​​groove 45 under the action of the compression spring 22, thereby achieving fixation and locking. When it is necessary to remove the collecting tube 2 from the sliding block 4, the locking blocks 21 at both ends are pressed towards the center, thereby being able to disengage from the snap-fit ​​groove 45.

[0031] By rotating the handle 32, the synchronous plate 3 can be driven to slide in the falling rod 1, thereby opening and closing the cover plate 41. The synchronous plate 3 can be easily moved by the user through the threaded drive. By setting multiple sliding rods 13 in the falling rod 1, it can be ensured that the synchronous plate 3 will not deviate when moving.

[0032] Preferably, a layer of sealant is provided on the ground of the cover plate 41 to ensure that the cover plate 41 can be tightly closed with the collection cylinder 2 after it is closed.

[0033] The drop bar 1 can be equipped with multiple sliding blocks 4 depending on its length, thus meeting different needs;

[0034] When using the device, the user first fixes multiple sliding blocks 4 with positioning bolts 5 according to specific needs to achieve the positioning of the collection depth. If there are extra sliding blocks 4 that are not used, they can be moved and fixed at the top or bottom. Then, the collection cylinder 2 is installed on the sliding block 4, and the handle 32 is turned to close the cover plate 41. The falling rod 1 can then be placed into the reactor. After the falling rod 1 contacts the bottom of the reactor, the handle 32 is turned to open the cover plate 41 to complete the collection of peroxides at different depths. After the collection is completed, the handle 32 is turned to close the cover plate 41, and the falling rod 1 can be lifted out of the reactor and the collection cylinder 2 can be removed to complete the sample collection.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
