The utility model relates to mechanical equipment technical field, concretely relates to a mobile multifunctional cleaning car, including the bearing platform, the bearing platform top is provided with reagent tank, reagent tank bottom outlet is connected with circulating pump, and the circulating pump output is connected with heating / cooler through pipeline, and heating / cooler fluid outlet is connected with the switching valve group for changing reagent flow direction, the switching valve group links respectively with reboiler and reagent tank, the water seal tank group is connected with tail gas recovery unit through pipeline at reagent tank top tail gas outlet, the utility model discloses through switching valve group changes reagent flow direction, supports'high in -low out'and'low in -high out'two modes, effectively removes the compact scale layer between the shell -side inner wall and the tube bundle of reboiler, promotes the thoroughness of cleaning, solves the pain point that traditional one -way cleaning is easy to leave dead angle.

This utility model discloses a graphite tube reactor, relating to the technical field of graphite tube reactors. It includes a counterweight base and a vertical plate welded to the top outer wall of the counterweight base. An angle adjustment seat is hinged to the upper part of the vertical plate, and the graphite tube reactor body is mounted on the angle adjustment seat. Two hydraulic cylinders are symmetrically hinged between the vertical plate and the angle adjustment seat. The graphite tube reactor body is equipped with a temperature-controlled stirring mechanism, which includes a T-shaped motor base, a temperature sensor, a cooling stirring component, and a heating stirring component. This utility model features a temperature-controlled stirring mechanism, which can intelligently and precisely control the reaction temperature inside the graphite tube reactor, thus improving the reaction efficiency. The control panel allows for simultaneous operation of the two hydraulic cylinders to flexibly adjust the tilt angle of the graphite tube reactor body, better meeting the needs of different applications.

This invention discloses a method for disrupting the cell walls of structurally heterogeneous microorganisms based on the synergistic vibration of multi-size media and its application. The method includes the following steps: (1) constructing a composite cell-dispersing media system with multi-size characteristics and filling it into a cell-dispersing tube; (2) injecting the microbial sample to be disrupted into the cell-dispersing tube and oscillating it at a linear velocity of 6-7 m / s for 30-90 seconds at 4-25 ℃; (3) after cell disruption, separating the mixed composite cell-dispersing media system and the solution to obtain a cell-dispersed solution containing intracellular products. The beneficial effects of this invention are: through the synergistic effect of multi-scale shear forces, it significantly improves the lysis efficiency of difficult-to-disrupt pathogens such as Mycobacterium tuberculosis, Cryptococcus, and Aspergillus, effectively protects the nucleic acid integrity of RNA viruses, has high cell disruption uniformity, good RNA protection, can be standardized and adapted to automated platforms, and is suitable for the pretreatment of complex clinical samples.
