Description

A steam pressure sterilizer

technical field

The invention relates to a sterilization device, in particular to a steam pressure sterilization device.

Background technique

High-pressure steam sterilization, high temperature and high pressure sterilization, can not only kill general bacteria, fungi and other microorganisms, but also have a killing effect on spores and spores. It is the most reliable and widely used physical sterilization method. The pressure steam sterilizer has the advantages of novel and beautiful shape, reasonable structure, complete functions, rapid heating and thorough sterilization. It is suitable for medical, scientific research, food and other units to sterilize surgical instruments, dressings, glassware, rubber products, food, medicinal liquid, culture medium and other items. There are many types and styles of high-pressure steam sterilizers, which can be divided into portable sterilizers, vertical pressure steam sterilizers and desktop (horizontal) pressure steam sterilizers. For example, CN 203507166U is a typical horizontal pressure sterilizer, which includes a sterilization chamber main body and an outer cover. A discharge pipeline is arranged at the bottom of the sterilization chamber main body, and a temperature sensor and a drain valve are sequentially arranged on the discharge pipeline. The main body of the sterilization chamber is provided with a safety valve, and when the internal pressure of the main body of the sterilization chamber exceeds a rated value, it will automatically release air and pressure. The horizontal pressure steam sterilization device is simple in structure, safe and reliable, and easy to operate. Another example is 201743952U, which is a typical portable sterilizer, which includes a pot cover, a pot body, a base, a disinfection inner barrel and an electric heating tube. The disinfection inner barrel is placed in the pot body, and the electric heating tube is installed under the disinfection inner barrel. Door opener. The sterilizer has the characteristics of thorough disinfection, simple operation and convenient use. After the conventional steam pressure sterilization device is sterilized, a large amount of water often remains inside. If it is not removed in time, it will cause corrosion and scaling on the inner wall, which will affect the performance of the sterilizer.

Contents of the invention

The technical problem to be solved by the present invention is to provide a steam pressure sterilizing device with a simple and reasonable structure, which can reduce the residual moisture inside the sterilizing device and avoid corrosion and scaling on the inner wall of the sterilizer.

In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions:

A steam pressure sterilization device, comprising a casing with an open upper end, inside the casing is provided with an upper sterilization barrel and a lower heating chamber; the upper end of the casing is provided with a cover that can freely cover the upper opening of the casing and seal the upper opening of the sterilization barrel The upper cover; the upper cover is equipped with a safety valve, a steam release valve and a pressure gauge. The pressure gauge is used to display the pressure in the sterilization tank, and the safety valve is used to automatically release the steam when the pressure in the sterilization tank is greater than the preset value. The steam release valve is used for manual steam release; the upper cover is also provided with a fastening nut, which is used to seal and lock the upper cover with the sterilization barrel; the heating chamber is connected with the lower end of the sterilization barrel, and the connection point is A groove, a sieve plate at the bottom of the groove, a sealing cover for sealing the groove is arranged above the groove, and the sealing cover can be freely taken out of the sterilization barrel; a heating tube is arranged in the heating chamber, and a The drain pipe connected with it, the drain valve is arranged on the drain pipe.

As a further improvement of the above technical solution:

The steam pressure sterilizing device is also provided with a suction drying system, the suction drying system includes a fan and a suction pipe, and the suction pipe is connected between the suction port of the fan and the discharge port of the drain pipe.

The section of the sealing cover is "T" shape, its lower part can be inserted into the groove, and the outer edge of its upper part is supported on the upper end of the groove when the lower part of the sealing cover is inserted into the groove. The pull ring on it.

The steam release valve is communicated with the inside of the sterilization barrel through the steam release pipe. There are four fastening nuts, which are evenly distributed on the upper edge of the upper cover. The upper cover is also provided with a handle.

The beneficial effects of the present invention are:

The sieve plate of the steam pressure sterilizing device of the present invention is set in the groove at the bottom of the sterilization barrel, and the top of it is covered and sealed with a sealing cover. The sealing cover can separate the sterilization barrel from the heating chamber, avoiding the water vapor in the heating chamber from entering the sterilization barrel, and the residual moisture in the sterilization barrel can evaporate quickly under the action of residual heat in the barrel, effectively reducing the corrosion of the inner wall and fouling.
