Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature experiment boxes, in particular to a constant temperature experiment box for storing NVP monomers. Background Art

[0002] NVP monomer, namely N-vinylpyrrolidone (N-vinylpyrrolidone), is an organic compound with the chemical formula C6H9NO. It is widely used in pharmaceuticals, cosmetics, coatings photocuring agents, inks and adhesives.

[0003] Existing constant temperature experimental boxes for storing NVP monomers often have complex structures and poor shock absorption, and there is a risk of reagent leakage when the constant temperature experimental box is moved. Utility Model Content

[0004] The main purpose of the utility model is to provide a constant temperature experimental box for storing NVP monomers, so as to solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A constant temperature experimental box for storing NVP monomers comprises a box body and a door. The connection between the box body and the door is provided with a hinge, and the door is provided with an observation window. A mesh plate is provided inside the box body, with multiple test tube placement holes. An insulating sponge is provided below the mesh plate. The insulating sponge has multiple test tube placement slots corresponding to the test tube placement holes. Test tubes are inserted into the corresponding test tube placement holes and test tube placement slots. A first vertical slot is provided on the right side of the insulating sponge, and a second vertical slot is provided on the left side of the insulating sponge. Multiple horizontal air ducts are connected between the first and second vertical slots. A heater is provided on the right side of the box body, and the heater's air outlet pipe is connected to the first vertical slot.

[0007] Furthermore, the air outlet at the end of the air outlet pipe faces the horizontal air duct.

[0008] Furthermore, an exhaust hole connected to the second vertical slot is provided on the left side of the mesh plate.

[0009] Furthermore, the top of the box is connected to a pressure relief pipe, and a pressure relief valve is provided on the pressure relief pipe.

[0010] Furthermore, the test tube is provided with a test tube stopper, and NVP monomers are stored in the test tube.

[0011] This utility model also includes other components that enable the normal operation of the constant temperature test box for NVP monomer storage. These devices or components all utilize conventional technologies in the art. Furthermore, devices and components not otherwise specified in this utility model, such as the pressure relief valve described herein, all utilize conventional technologies in the art. During implementation, appropriate device or component models can be selected based on the specific work scenario.

[0012] The working principle of this utility model is that an insulating sponge surrounds the test tubes storing NVP monomers. Warm air from a heater passes through a first vertical slot, a horizontal air duct, and a second vertical slot to heat the insulating sponge, improving thermal insulation performance while simplifying the device structure. The insulating sponge is placed inside the box, and the test tubes are placed in the test tube storage slots of the insulating sponge, effectively buffering external impacts and reducing the risk of reagent leakage when the constant temperature experimental box is moved.

[0013] Compared with the prior art, the utility model has the following beneficial effects: simple structure, good heat preservation, good shock absorption, and reduced risk of reagent leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0017] Example:

[0018] like Figure 1As shown, a constant temperature experimental box for storing NVP monomers comprises a box body 1 and a door 2. The connection between the box body 1 and the door 2 is provided with a hinge 12, and the door 2 is provided with an observation window 11. A mesh panel 3 is provided inside the box body 1, with multiple test tube placement holes 31. Below the mesh panel 3 is an insulating sponge 4, which has multiple test tube placement slots 44 corresponding to the test tube placement holes 31. Test tubes 5 are inserted into the corresponding test tube placement holes 31 and test tube placement slots 44. Test tubes 5 are fitted with test tube plugs 52, and NVP monomers 51 are stored in the test tubes 5. A first vertical slot 41 is provided on the right side of the insulating sponge 4, and a second vertical slot 43 is provided on the left side of the insulating sponge 4. Multiple horizontal air ducts 42 connect the first and second vertical slots 41 and 43. A heater 6 is provided on the right side of the box body 1. An outlet duct 7 of the heater 6 is connected to the first vertical slot 41, and an outlet 8 at the end of the outlet duct 7 faces the horizontal air duct 42.

[0020] The present invention provides a constant-temperature experimental box for storing NVP monomers. The operating principle is as follows: an insulating sponge 4 surrounds a test tube 5 storing NVP monomers 51. Warm air from a heater 6 passes through a first vertical slot 41, a horizontal air duct 42, and a second vertical slot 43 to heat the insulating sponge 4, improving thermal insulation performance while simplifying the device structure. The insulating sponge 4 is placed within the box 1, and the test tube 5 is placed within the test tube placement slot 44 of the insulating sponge 4. This effectively cushions external impacts and reduces the risk of reagent leakage during movement of the constant-temperature experimental box.
