Glass reactor has the characteristics of no pollution, high temperature resistance, corrosion resistance, hygiene, and fast heating speed.

[0003] The current glass reactor has certain defects when used. When the reactor needs to maintain a constant temperature or avoid excessive temperature during certain reaction processes, an insulating shell is installed on the outside of the reactor to reduce heat loss or prevent external heat from affecting the reaction process. However, the insulating shell on the outside of the reactor is opaque, and the shell of the glass reactor cannot be effectively observed when it is used. When the reactor overheats and expands, the expansion change of the reactor cannot be detected in time, resulting in poor explosion-proof effect of the reactor and low safety and reliability of the reactor. Therefore, a glass explosion-proof reactor is now proposed. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-Figure 2 The present embodiment provides a glass explosion-proof reactor, comprising a glass reactor body 1, two protective shells 2 are arranged outside the reactor body 1, a hinge 3 is arranged between the two protective shells 2, and the two protective shells 2 are hingedly connected by the hinge 3, the curvature of the protective shell 2 is the same as the curvature of the shell of the reactor body 1, after the two protective shells 2 are sleeved on the outside of the reactor body 1, the connecting bolts 6 are screwed on the connecting plates 5 of the protective shells 2, and the two protective shells 2 are locked and fixed to the outside of the reactor body 1 by the connecting bolts 6, so that the protective shells 2 play a role of heat insulation protection, a pressure detection component 4 is arranged between the inner wall of the protective shell 2 and the outer wall of the reactor body 1, and the pressure detection component 4 is used to detect the expansion degree of the reactor body 1, so that the expansion degree can be detected in time when the reactor body 1 is overheated and expanded, so as to avoid the reactor body 1 from bursting.

[0023] Reference Figure 3-Figure 4 The protective shell 2 includes a heat insulation cover 21, and a buffer sponge 22 is arranged on the outer arc surface of the heat insulation cover 21. The outer surface of the buffer sponge 22 is wavy. The buffer sponge 22 is used to realize the buffer protection of the protective shell 2. When the kettle body 1 is collided, the buffer sponge 22 can be used to buffer the impact force, thereby effectively protecting the kettle body 1. A rubber ring 24 is arranged on the inner arc surface of the heat insulation cover 21 through a slot 23. The outer ring of the rubber ring 24 is arc-shaped, and the outer ring of the rubber ring 24 protrudes from the inner arc surface of the heat insulation cover 21. When the protective shell 2 is installed on the outside of the kettle body 1, the rubber ring 24 protruding from the inner arc surface of the heat insulation cover 21 first contacts the outside of the kettle body 1. As the protective shell 2 is locked and fixed, the rubber ring 24 is compressed, which can not only protect the kettle body 1, but also prevent the rubber ring 24 from slipping, thereby preventing the protective shell 2 from detaching from the kettle body 1.

[0024] Among them, the heat insulation cover 21 includes a cover shell 211, the cover shell 211 is a double-layer structure, and an insulation core 212 is arranged between the double-layer cover shells 211. The material of the insulation core 212 adopts one of rock wool, glass fiber and ceramic fiber. The insulation core 212 is used to make the heat insulation cover 21 have excellent insulation performance. When the kettle body 1 is in use, it can effectively insulate and prevent the kettle body 1 from being disturbed by the external ambient temperature, thereby improving the use effect of the reactor.

[0025] Reference Figure 5 The pressure detection component 4 includes a thin film pressure sensor 41. The thin film pressure sensor 41 adopts the RP-C30-ST model and can detect a pressure of 20g-20kg. The thin film pressure sensor 41 is fixed to the inner wall of the protective shell 2 by an adhesive pad 42. A flexible circuit board 43 is arranged on the thin film pressure sensor 41. After the thin film pressure sensor 41 is fixed by the adhesive pad 42, the thin film pressure sensor 41 is squeezed when the kettle body 1 expands due to heat. The thin film pressure sensor 41 transmits the pressure data to the signal receiving device through the flexible circuit board 43, so that the expansion data of the kettle body 1 can be monitored in real time. When the kettle body 1 is overheated, the expansion degree can be responded to promptly and quickly, thereby avoiding the kettle body 1 from bursting and being damaged, and improving the safety of the glass reactor when in use.

[0026] Working principle: When using the glass reactor of the present application, the heat insulation cover 21 is put on the outside of the reactor body 1, and then the heat insulation cover 21 is locked and fixed by using the connecting bolts 6 on the connecting plate 5. The rubber ring 24 on the card slot 23 in the heat insulation cover 21 plays an anti-slip role, so that the heat insulation cover 21 can be fixed on the outside of the reactor body 1. The heat insulation cover 21 is used for heat insulation to prevent the reactor body 1 from being disturbed by the external ambient temperature, thereby improving the use effect of the reactor. When the reactor body 1 expands due to heat, the film pressure sensor 41 is squeezed, and the film pressure sensor 41 transmits the pressure data to the signal receiving device through the flexible circuit board 43, so that the expansion data of the reactor body 1 can be monitored in real time. When the reactor body 1 is overheated, the expansion degree can be responded to quickly and timely, thereby avoiding the explosion and damage of the reactor body 1, thereby improving the safety of the glass reactor when in use.
