The invention discloses a hotel meal delivery robot and its working method, comprising a box body, an infrared detector, a terminal processor, an exhaust fan, an electric telescopic rod, an electric mechanical arm, and an electric wheel. The top of the box body is fixedly installed with The control box, the terminal processor is installed on the inner wall of the control box, the infrared detector is fixedly installed on the inner wall of the control box, the inside of the box is provided with a suction groove, and the exhaust air The machine is fixedly installed on the outer wall of the box body, the suction port of the exhaust fan is connected with the suction groove, the sliding plate moves to the left, the sealing plate overcomes the elastic force of the torsion spring and rotates outward, and then enters the sliding groove to realize When the box is opened, the moving box drives the tableware to move to the outside of the box, starts the electric mechanical arm, and the electric mechanical arm moves upwards to press against the clamping groove set on the outer wall of the anti-scalding handle to take out the dishes and serve as a service The protective function of personnel's hand can avoid the occurrence of scald accidents.

The invention discloses a plasma adsorption filtration device for producing blood coagulation factor blood products. The plasma adsorption filtration device comprises a plasma adsorption tank, a plasma conveying system and a gel filter, wherein a speed-adjustable stirring device, a plasma inlet and a gel adding hole are arranged at the top end of the plasma adsorption tank; a temperature control interlayer is arranged on the tank, and a plasma outlet is formed in the bottom end of the tank; the plasma conveying system consists of a liquid material conveying pipe and a liquid material conveyingpump; a speed-adjustable stirring scraper is arranged at the top end of the gel filter; an inner filter screen is arranged inside the gel filter; a gel outlet is formed in the bottom end of the gel filter; a feed port and a discharge port are formed in the upper end and the lower end of the side surface of the gel filter respectively; the gel filter is provided with an automatic solid stripping system with a differential pressure controller. The plasma adsorption filtration device achieves streamlined treatment of automatic gel filtration and collection in the production process of the bloodcoagulation factor blood products, so that the labor intensity of working staff is greatly reduced; meanwhile, the pressure difference is stable and controllable in the whole filtration process, so that the blood coagulation factor components and gel particles are better protected.

The invention discloses a rotor pump and an assembly method thereof, belonging to the technical field of rotor pumps. The rotor pump includes a casing; a first transmission shaft, one end of which is provided with a first bearing, and the first bearing is arranged in a first bearing seat on the casing, and the first transmission shaft is provided with a first Rotor; second transmission shaft, which is parallel to the first transmission shaft, the second transmission shaft is provided with a second rotor, one end of the second transmission shaft is provided with a second bearing, and the second bearing In the second bearing seat provided on the housing, injection molding grooves are provided on the outer peripheral wall of the second bearing and / or on the upper ring of the inner peripheral wall of the second bearing seat for injection molding and containing injection molding agent. Its advantage is that it can adjust the rotation gap between the first rotor and the second rotor without disassembly, and at the same time keep the rotation gap between the first rotor and the second rotor unchanged during the rotation process .

The invention discloses a method of grouting damage reduction using roof collapse and bulge filling and directional drilling point source type interval grouting; after coal mining operations, the roof naturally collapses to form a state of complete filling or nearly complete filling. First, the interval grouting method is adopted. Downhole directional drilling to the upper part of the caving broken body, and simultaneous laying of PVC casing and grouting pipe to realize fixed-point grouting; among them, the performance of the grouting material is selected with reference to relevant national standards and the targeted mix design is selected to select the appropriate quick-setting Precisely control the initial setting time of the grout; then, by laying out a grouting flow meter and a grouting pressure gauge on the grouting pipeline, the accurate and real-time monitoring of the grouting amount is realized, and the spiral nozzle is used for planar jet grouting. The amount and speed of grouting are determined by controlling the pressure of the grouting pipe and monitoring the flow rate, and finally form a point-source interval grouting pile layout scheme.
