Description

Technical Field

[0001] The utility model relates to the technical field of pyrolysis analyzers, in particular to a food safety thermal pyrolysis analyzer. Background Art

[0002] There are many kinds of materials used in plastic food packaging bags in the circulation market. People come into contact with them every day, but they don’t know whether these daily plastic food bags can be in direct contact with food. At present, the materials commonly used for plastic food bags are: polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC) and recycled plastics (mixed plastics), etc. Among them, the country has long stipulated that plastic bags made of polyvinyl chloride (PVC) cannot be used for direct contact with oily foods, cooked foods, and hot foods. However, according to incomplete statistics and media reports, there are still quite a few fresh-keeping bags made of polyvinyl chloride (PVC) or mixed plastics in the market that are in direct contact with oily cooked foods. This is a violation of food safety. Therefore, it is necessary to use a thermal cracking analyzer to quickly determine the material of plastic food packaging bags;

[0003] Existing food safety thermal cracking analyzers need to heat the solid sample to instantly crack and resolve the high-boiling point organic matter in the sample under test, turning it into gas that can be used for gas chromatography analysis, and then enter the gas chromatograph for analysis and identification. However, traditional food safety thermal cracking analyzers dissipate internal heat through ventilation holes, which results in poor heat dissipation effect.

[0004] Therefore, a food safety thermal cracking analyzer is proposed. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a food safety pyrolysis analyzer to solve the problem that the traditional food safety pyrolysis analyzer only dissipates its internal heat through ventilation holes, which leads to poor heat dissipation effect.

[0006] Based on the above purpose, the utility model provides a food safety pyrolysis analyzer, including a chassis, on which a ventilation and heat dissipation component is provided;

[0007] The ventilation and heat dissipation component includes an air inlet and an air outlet opened inside the chassis, the air inlet is provided with a mounting frame, a driving motor is provided inside the mounting frame, a fan is fixedly connected to the output end of the driving motor, and a filter is movably provided inside the mounting frame, and a connecting component for connection is provided on the filter;

[0008] The connecting component includes a block fixedly installed on the side of the filter screen, a slot matched with the block is opened on the side of the installation frame, and a positioning frame matched with the block is fixedly connected to the side of the installation frame, a mounting groove is opened on the side of the block, a return spring is fixedly connected to the inner wall of the mounting groove, a wedge block is fixedly connected to the end of the return spring, and a fixing hole matched with the wedge block is opened on the inner wall of the positioning frame.

[0009] As a further optimization solution of the utility model, an inner wall of the positioning frame is provided with an inclined groove matched with the wedge block.

[0010] As a further optimization solution of the present invention, there are two groups of connecting components, and the two groups of connecting components are symmetrically distributed along the vertical center axis of the filter screen.

[0011] As a further optimization solution of the utility model, the overall structure formed by the reset spring and the wedge block of each set of connecting parts has two groups, and is symmetrically distributed along the horizontal center axis of the clamping block.

[0012] As a further optimization solution of the utility model, a bearing frame is fixedly connected to the inner wall of the installation frame, and the filter screen is in contact with the side surface of the bearing frame.

[0013] As a further optimization solution of the utility model, a dustproof net is provided on the air outlet.

[0014] Beneficial effects of the utility model:

[0015] 1. The present application sets a ventilation and heat dissipation component. Under the cooperation of the driving motor, the fan and the filter, the driving motor works so that the driving motor can drive the fan to rotate, thereby delivering the outside air into the chassis for exchanging the hot air flow in the chassis, thereby quickly dissipating the heat in the chassis and improving the heat dissipation efficiency of the chassis;

[0016] 2. The present application sets a connecting component, and under the interaction of the card block, the card slot, the positioning frame, the return spring, the wedge block and the fixing hole, the wedge block in the fixing hole is squeezed by hand pressure or with the help of external tools, so that the wedge block can compress the return spring into the installation groove until the end of the wedge block moves into the positioning frame, and the filter net is pulled, so that the card block can be removed from the positioning frame, completing the rapid disassembly of the filter net, facilitating the installation of a new filter net to improve its filtration efficiency.
