Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sterilization equipment, and in particular relates to a solid-liquid separation device resistant to high temperature and high pressure. Background Art
[0002] In the process of microbial detection, glass culture dishes are often used for solid culture. The solid culture medium contains 1.5-2.0% agar. In order to ensure environmental biosafety, the samples after culture must be sterilized by high-temperature steam before they can be discarded.
[0003] High temperature will liquefy the solid culture medium in the culture dish, thereby mixing the culture dish, liquid culture medium, cultured bacteria therein, and testing supplies together. It is usually necessary to manually separate the solid and liquid, sort the glassware and non-disposable testing supplies, and clean them for later use. The liquefied culture medium, cultured bacteria and disposable testing supplies are packaged and handed over to professional institutions for processing. The sorting work is cumbersome and time-consuming. Utility Model Content
[0004] The utility model aims to solve the technical problems existing in the background technology and provide a high-temperature and high-pressure resistant solid-liquid separation device, which can effectively avoid operators from sorting glass culture dishes from waste with bare hands. The design of double-layer fixing of a sterilization barrel and a mesh basket buckle is adopted, which can effectively separate solid and liquid while ensuring the sterilization effect. Moreover, a sterilization bag is provided between the sterilization barrel and the mesh basket for directly packaging liquid waste after sterilization. The whole device is easy to use, significantly shortens the sorting operation time, and improves the sorting efficiency.
[0005] In order to achieve the above technical objectives, the utility model adopts the following technical solutions:
[0006] A high temperature and high pressure resistant solid-liquid separation device, comprising a sterilization barrel and a net basket placed inside the sterilization barrel;
[0007] The upper edge of the net basket overlaps the upper edge of the sterilization barrel;
[0008] The bottom of the net basket is provided with a plurality of mesh holes;
[0009] A sterilization bag is also provided between the sterilization barrel and the net basket. The sterilization bag is used to be sleeved inside the sterilization barrel and outside the net basket, and is used to directly encapsulate liquid waste after sterilization.
[0010] Furthermore, a buckle is provided on the upper edge of the net basket, and the net basket is overlapped with the upper edge of the sterilization barrel through the buckle.
[0011] Furthermore, there are 2-4 buckles, which are evenly spaced on the upper edge of the basket.
[0012] Furthermore, when the upper edge of the mesh basket overlaps the upper edge of the sterilization barrel, the bottom of the mesh basket is at a certain height distance from the bottom of the sterilization barrel.
[0013] Furthermore, the height distance between the bottom of the net basket and the bottom of the sterilization barrel is 1 / 3-2 / 3 of the inner height of the sterilization barrel.
[0014] Furthermore, the mesh holes at the bottom of the basket are arranged in a circular array.
[0015] Furthermore, the side wall of the mesh basket is also provided with a plurality of mesh holes, and the mesh holes are evenly spaced around the side wall of the mesh basket.
[0016] Furthermore, the volume of the sterilization bag is larger than that of the sterilization barrel. After the sterilization bag is put into the sterilization barrel, the outer edge of the sterilization bag extends beyond the upper edge of the sterilization barrel.
[0017] Furthermore, a handle is provided at the upper end of the net basket.
[0018] Furthermore, the sterilization barrel is a stainless steel sterilization barrel.
