Description

Technical Field

[0001] The utility model relates to the field of design and use of a synthesis reactor, in particular to a hydrothermal reaction synthesis reactor. Background Art

[0002] The hydrothermal synthesis reactor is a small reactor commonly used in chemical laboratories. It can be used for small-dose synthesis reactions. It can also use the strong acid or strong base and high temperature and high pressure closed environment in the tank to achieve the purpose of quickly digesting insoluble substances.

[0003] After the reaction of a conventional reactor is completed, when opening the lid of the reactor, one hand basically holds the reactor body and the other hand opens the lid. If the time is not enough, the internal high-temperature gas may rush out and burn the staff. Therefore, some tools are usually used to cool down or release the pressure, but these tools need to be prepared separately. If they are designed directly on the reactor, the cost will increase significantly.

[0004] In addition, most reactor bodies have a fixed height. If you want to increase the capacity, you need to replace the reactor. Therefore, some designs will add a detachable outer wall of the reactor. Most of these designs still use threaded connections, but in actual use, when tightening and removing the reactor cover, it may cause the heightened part to change in displacement. Therefore, it would be more convenient if it could be fixed with simple tools. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the hot air rushing out may burn the staff, the new design can be disassembled and used when needed, and the structure of the heightened part is easily affected by the disassembly and assembly process of the kettle cover.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is as follows: The utility model is a hydrothermal reaction synthesis reactor, including a reactor body, a bushing and a reactor cover, the bushing is placed in the reactor body, the reactor cover is threadedly connected to the reactor body, a plurality of groups of heightening rings are threadedly connected on the reactor body, the heightening rings are threadedly connected to the reactor cover, a limiting structure is provided on the heightening rings and the reactor body, an outer ring is provided on the reactor body, a positioning protector is installed on the outer ring, the positioning protector includes an external sleeve and a mounting structure, the external sleeve is slidably sleeved on the outer ring, and the mounting structure is arranged in the external sleeve.

[0007] Furthermore, the outer ring is provided with a plurality of mounting grooves, and the external sleeve is provided with a plurality of embedding grooves.

[0008] Furthermore, the mounting structure is provided with a plurality of groups, and the mounting structures are respectively located in a group of embedding grooves, and the mounting structure comprises a spring and an insertion pin, the spring is provided on the external sleeve and is located in the embedding groove, and the insertion pin is provided on the spring.

[0009] Furthermore, the front side of the insertion pin is an arc-shaped structure, and the insertion pin is located in the installation groove.

[0010] Furthermore, the limiting structure is provided with multiple groups, and the limiting structure includes positioning buckles and positioning sleeves, the positioning buckles are respectively arranged on the kettle body and the heightening ring, and the positioning sleeves are snap-fitted and slidably sleeved on the multiple groups of positioning buckles.

[0011] Furthermore, the external sleeve is provided with a plurality of groups of positioning holes.

[0012] Furthermore, a through hole is provided on the kettle cover, a lever is slidably provided in the through hole, and a handle is provided on the lever.

[0013] Preferably, the side surface of the positioning buckle is in an I-shaped structure.

[0014] The beneficial effects achieved by the utility model using the above structure are as follows:

[0015] 1. The positioning protector in this design is used when needed, and the disassembly and assembly is very convenient and simple, without wasting too much work time. The hand is under the external sleeve, and there is a certain isolation between the opening position, which can block the hot air and reduce the risk of hot air burning the staff's hands. The other hand can also use a lever to maintain a certain distance.

[0016] 2. The design of the limiting structure can quickly position the kettle body and the heightening ring, and the position of the heightening ring will not be affected during the process of disassembling and assembling the kettle cover. BRIEF DESCRIPTION OF THE DRAWINGS
