The inlet of the protective gas is provided at the top of at least one layer of the protective gas pipeline. The invention is used in a coal gasification device.

The invention provides an installation method of a large diameter pipeline, which has the advantages of simple and easy implementation, time saving and labor saving during the installation at the over-bent area. The installation method of the large diameter pipeline adopts a rubber gasket type mouthing pipe and a rubber gasket matching with the mouthing pipe. The invention is characterized in that the rubber gasket type mouthing pipe is 1 to 2 meters in length and is connected with the rubber gasket by a sealing way. The rubber gasket is of the well-known and common random model, and the preferable model is a R type rubber gasket. The rubber gasket type mouthing pipe is the well-known and common random material, and the preferable material is the PVC-U pipe. The diameter of the rubber gasket type mouthing pipe is Phi 250 to Phi 315 millimeter. Due to adopting the rubber gasket type mouthing pipe with 1 to 2 meters of length, the length is greatly decreased by compared with 6 meter of the original length, therefore, when the rubber gasket type mouthing pipe is put into the over-bent area after direct connecting with the rubber gasket, the pipeline can be naturally shaped according to the excavation direction, and any auxiliary facility is not required. The installation procedure has the advantages of simple and easy implementation, time saving and labor saving, greatly decreasing the installation cost, enabling water to flow smoothly and not being easily leaked and lost.

The invention relates to a vibrationless fluidized bed drying machine, which belongs to the field of mechanical equipment and comprises a base, a box body, a heat exchanger, a draught fan and a deduster, wherein the box body is arranged on the base, an air outlet of the box body is connected with the draught fan, the draught fan is connected with the deduster, an air distribution plate is arranged in the box body, the box body is partitioned into an upper box body and a lower box body by the air distribution plate, lower partition boards are arranged in the lower box body, the lower box body is partitioned into a plurality of air chambers by the lower partition boards, upper partition boards are arranged in the upper box body corresponding to the lower partition boards, the top of the upper box body is provided with an upper ventilation duct, a blast device is arranged between two adjacent lower partition boards, and the blast device is connected with the heat exchanger. A duct is divided into the upper ventilation duct and a lower ventilation duct by the upper partition boards of the upper box body, air quantity of the upper ventilation duct and the lower ventilation duct can be adjusted by an adjusting plate so as to achieve an uniform discharge effect; the blast device is arranged between the two adjacent lower partition boards in the lower box body, energy is saved, the air quantity can be respectively adjusted according to different moisture contents of materials to obtain qualified materials; and the original vibration device is replaced by a material poking device to avoid the phenomenon of bed blocking.

The invention discloses a laboratory multi-function cold and hot water unit testing equipment, which includes a four-way pipe and a connecting piece, the connecting piece is connected with the center of the bottom of the four-way pipe, and two adjacent ports of the four-way pipe A plug is screwed and connected, and a round hole is opened at the center of the outer surface of the plug, and a nut ring is fixed on the outer surface of the plug corresponding to the position of the round hole. In the present invention, the laboratory chiller test equipment is designed through the four-way pipe, which can reduce the types of equipment, reduce the number of elbows, and reduce the manufacturing cost of the equipment. By setting the plug and screwing the connecting stud on the plug, the four-way The criss-cross structure of the pipe, and the automatic exhaust valve connected to the top center of the four-way pipe can ensure the smooth direction of water flow. The test end of the tester can fully contact with water, thus ensuring the accuracy of the experimental measurement.

The invention discloses a full-automatic medical cleaning machine. The full-automatic medical cleaning machine comprises a frame, a cleaning bin and a water pump, wherein a cleaning frame is positioned in the cleaning bin; a water inlet is formed in the lower end of the cleaning frame; a water inlet main pipe is arranged at one side of the cleaning frame, and is connected with the water inlet; a main water pipe is arranged at the bottom of the cleaning bin; a joint device is arranged at a water outlet end of the main water pipe; a butt joint ring is arranged in a pipe hole in the upper end of the joint device; a water inlet end of the main water pipe is connected with the water pump; when water is supplied into the cleaning bin, the water pump is started, and the butt joint ring in the joint device is upwards flushed by water pressure under water pressure impact provided by the water pump, so that the top surface of the butt joint ring is tightly butted to the periphery of the water inlet in the bottom surface of the cleaning frame; and when the water is stopped being supplied into the cleaning bin, the butt joint ring in the joint device downwards drops to reset under the effect of self gravity. The full-automatic medical cleaning machine adopts the novel joint device, so that the use level of water pipes is reduced, the water resource is saved, the space in the cleaning bin is enlarged, and the cleaning capacity is improved.
