The utility model relates to exhaust treatment technical field especially, more related to a kind of exhaust catalytic combustion device convenient to gas fitting replacement, including combustion reaction bin, support track, auxiliary strut, connecting block and combustion mechanism, the support track fixedly arranged in the combustion reaction bin inside, the auxiliary strut is fixed with combustion reaction bin inside, the connecting block fixedly arranged in combustion reaction bin outside, the combustion mechanism is clamped and set in combustion reaction bin inside, this convenient to gas fitting replacement's exhaust catalytic combustion device in working condition, large-area surface burner work guarantee to carry out combustion reaction in the oil gas and harmful gas in tail gas, greatly reduce harmful gas content in tail gas, in maintenance process, guarantee the support strength of combustion reaction bin, and it is convenient to integral removal and replacement maintenance, when removal and maintenance, guarantee bottom support and limiting effect, avoid direct drop-off and cause end drop, to improve security.

The invention discloses a nitrogen oxide sensor chip for industry, which relates to the technical field of nitrogen oxide sensors, and comprises a corona component and a zirconia matrix respectively connected to both ends of an air filter element, wherein the corona component is used to perform corona treatment on the air entering the zirconia matrix, so that sulfur dioxide gas in the air forms sulfuric acid aerosol, which is neutralized and absorbed by a solid absorbent contained in the air filter element, so as to reduce the content of harmful gases in the air, protect the zirconia matrix, and make the nitrogen oxide sensor chip suitable for industrial applications. The corona component and the zirconia matrix of the invention are both plugged into the air filter element, and are easy to disassemble and assemble.

The invention relates to the technical field of electronic manufacturing, in particular to an SMT (surface mount technology) dispensing device which comprises a table body, a conveying table and a frame body are mounted on the end face of the table body, a tray is mounted on the surface of the conveying table, and the SMT dispensing device further comprises a dispensing mechanism used for dripping glue on a circuit board so as to mount an electronic component on the circuit board, the dispensing mechanism is mounted on the surface of the frame body; and the cutting-off and cleaning mechanism is used for cutting off the glue when the glue wire drawing phenomenon occurs after the glue is dripped on the circuit board by the glue dispensing mechanism. By arranging the electric push rod, the cut-off plate and the groove, by means of a driving system of the electric push rod and through accurate movement of the cut-off plate, glue drawn wires generated after glue dripping can be effectively cut off. The design of the cut-off plate comprises the grooves, and the cut-off glue can be effectively gathered together by using the grooves, so that the residual and condensation problems of the glue on the surface of the cut-off plate can be obviously reduced.

The invention discloses a mixed biological feed and a preparation method thereof. The preparation method comprises the following steps: selection and preparation of raw materials, and fermentation treatment; drying and crushing; in conclusion, by adding microorganisms and enzymes, complex substances such as cellulose and hemicellulose in the feed can be decomposed, so that the digestibility and nutritional value of the feed are improved. The microorganisms can further synthesize B vitamins, amino acids and other nutrient substances, further supplement nutrients needed by animals and promote animal growth. Probiotics in the biological mixed feed can compete with harmful bacteria in intestinal tracts for living space and nutrient substances, so that reproduction of the harmful bacteria is inhibited, and intestinal flora balance is maintained. Meanwhile, the probiotics can generate antibacterial substances such as organic acid and bacteriocin, the barrier function of the intestinal tract is enhanced, invasion of pathogenic bacteria is reduced, and therefore the immunity of animals is improved; the breeding environment is improved and pollution is reduced. The probiotics can decompose and utilize some difficult-to-digest substances in animal bodies.
