Embodiment 1

[0059] Embodiments of the present invention provide a laboratory autoclave, such as Figure 1-3As shown, including the tank body 1 and the tank cover 4 installed on the tank body 1, rollers 13 can be evenly and symmetrically installed on the bottom of the tank body 1 to facilitate movement. The tank cover 4 is equipped with a manual air release valve 5 and a pressure gauge 6. The manual air release valve 5 is used to discharge the air in the tank body 1, the pressure gauge 6 is used to monitor the pressure in the tank body 1, and the tank cover 4 is equipped with a handle for easy access;

[0060] The autoclave also includes:

[0061] The placing net frame 3 arranged in the tank body 1 is used for placing items to be sterilized, such as laboratory test tubes, beakers, Erlenmeyer flasks and other tools;

[0062] The heating assembly arranged on the tank body 1 is used to heat the water in the tank body 1 to generate water vapor;

[0063] A connection assembly 7 for quickly co...

Embodiment 2

[0081] This embodiment is on the basis of embodiment 1, as Figure 4-5 shown, also includes:

[0082] A plurality of deflectors 25 arranged on the outside of the screen frame 3 are used to guide the rising water vapor into the screen frame 3, and the plurality of deflectors 25 are fixed on the inner wall of the tank body 1 at intervals from top to bottom , the distance between a plurality of shrouds 25 and the placement screen frame 3 gradually increases from top to bottom;

[0083] Water vapor all moves upwards directly, causing a certain degree of loss, and is also unfavorable for the side sterilization of the article. Through the guide cover 25, its inner side wall is inwardly arc-shaped, and the rising water vapor is changed to flow direction, from the placement net. The side of the frame 3 flows into the net frame to sterilize the side of the article, which improves the sterilization effect.

[0084] Preferably, the bottom end of the connection sleeve 2 is fixed with a ...

Embodiment 3

[0086] This embodiment is on the basis of embodiment 2, as Figure 6-7 As shown, it also includes a plurality of groups of guide assemblies mounted on the support net plate 9 at intervals in the circumferential direction, and the guide assemblies include:

[0087] At least one fan blade 26 installed on the supporting grid plate 9 and distributed radially through the installation shaft;

[0088] Worm wheel 27 fixed on the mounting shaft;

[0089] Rotate the worm screw 29 installed on the support screen 9, the worm screw 29 is engaged with the worm wheel 27;

[0090] The impeller 28 fixed on the worm 29, the impeller 28 is partly submerged in the water in the tank body 1, and the impeller 28 is driven to rotate by hydraulic force so that the worm 29 rotates, and the blades of the impeller 28 are preferably arc-shaped;

[0091] When the rotating shaft 10 drives the support screen 9 to rotate, the impeller 28 revolves accordingly and moves relative to the water. The force of the...

Abstract

The invention is applicable to the technical field of high-pressure sterilizers, and provides a laboratory high-pressure sterilizer which comprises a tank body and a tank cover mounted on the tank body, and further comprises a placing screen frame arranged in the tank body, a heating assembly arranged on the tank body and a connecting assembly, the connecting assembly comprises an inserting rod, a connecting hole, a wedge-shaped elastic gasket, a connecting pin, a first driving ring and a positioning piece, and a sealing assembly is arranged and comprises a first sealing ring and a second sealing ring; the driving assembly is used for driving the placing screen frame to rotate, the multiple flow guide covers are arranged, by arranging the connecting assembly, operation is easy, the tank body and the tank cover are rapidly disassembled and assembled, nuts do not need to be screwed one by one for fixing, and the working efficiency is improved; the sealing assembly is arranged for three-layer sealing, and the sealing effect is good; the driving assembly is arranged, so that the to-be-sterilized articles placed in the screen frame are in full contact with the high-temperature saturated water vapor; and the flow guide cover is arranged and used for guiding rising water vapor into the placing net frame, so that the side faces of the articles are sterilized, and the sterilization effect is improved.

Description

technical field [0001] The invention belongs to the technical field of high-pressure sterilizers, in particular to a laboratory high-pressure sterilizer. Background technique [0002] Autoclave is a device that uses saturated pressure steam to quickly and reliably sterilize and sterilize items. Using high-temperature saturated steam within a certain period of time can denature the protein of microorganisms and cause the death of microorganisms to achieve the purpose of sterilization. Disinfect and sterilize medical devices, dressings, glassware, solution culture media, etc.; [0003] The connection between the tank body and the tank cover of some existing autoclaves is installed through the cooperation of multiple bolts and multiple nuts. It needs to be fixed by screwing the nuts one by one, which takes a long time and is troublesome. Contents of the invention [0004] The present invention provides a laboratory autoclave, aiming to solve the above problems. [0005] The...
