The invention discloses a W-flame boiler with multiple groups of burnout air nozzles. A plurality of burnout air nozzle groups are arranged at the lower part of the upper furnace, and the multiple burnout air nozzle groups in each burnout air nozzle group are respectively arranged in The front wall and rear wall of the upper furnace, and the wind blown out by the multiple burn-up air vents in each burn-up air vent group forms an imaginary tangent circle in the center of the upper furnace; each burn-up air vent group The number of the plurality of burnout air vents is 3 or more. The W-flame boiler with multiple groups of burn-out air nozzles of the present invention can strengthen the mixing of the air in the upper furnace area with the unburned pulverized coal, enhance the filling degree of the flue gas in the upper furnace area, and improve the burn-out rate of the pulverized coal in the later stage. Reducing the carbon content and carbon monoxide content of fly ash, especially in the case of large deviation of the primary air powder of the boiler, can achieve the purpose of reducing the NOx emission of the boiler on the premise of ensuring the normal boiler steam-water parameters and the boiler thermal efficiency not reducing.

The invention provides a guide groove for screw-thread steel slitting and rolling. The guide groove comprises two side plates and a partition plate located between the two side plates, and a piece rolling channel is formed between the corresponding side plate and the partition plate; the guide groove further comprises a restraint device arranged on the side plates, and the restraint device comprises guide wheels and supporting arms; the guide wheels are rotatably arranged and located at outlets of the piece rolling channels, the axes are in the vertical direction, and the circumferential faces of the guide wheels protrude inwards the piece rolling channels and are at least flush with the inner surfaces of the side plates; the supporting arms are arranged at the outlets of the piece rolling channels, and the guide wheels are rotatably arranged on the supporting arms. The restraint device with an adjustable function is preferably provided, the restraint device is adjusted according to the filling degree of actual screw-thread steel cross ribs at a production scene, accordingly the ideal size and satiation degree of reinforced cross ribs are obtained, and the quality control level is stabilized.

The invention discloses a sleeve-crevice-preventing sleeve-and-sleeve-strip-lining-integration tailoring method, and belongs to a suit tailoring production method. The technical problems that in a traditional sleeve-and-sleeve-lining tailoring operation method, the operation difficulty is large, the efficiency is low, and the appearance quality of a suit is not guaranteed are solved. According to the technical scheme, the tailoring method includes the following steps that (1) a sleeve cutter opening is formed in a sleeve sheet, a cutter opening corresponding to the sleeve cutter opening is formed in a front sleeve lining of a sleeve strip lining, and after the cutter opening in the front sleeve lining is aligned to the sleeve cutter opening, and the front sleeve lining is directly boned to the sleeve sheet; (2) a sleeve cotton strip of the sleeve strip lining is tailored to an upper layer of the front sleeve lining in the step (1) with a seam line according to the seam allowance of 0.4 cm to 0.6 cm, and the sleeve cotton strip and the front sleeve lining are jointly tailored on the sleeve sheet; (3) the sleeve sheet in the step (2) is tailored to a sleeve; (4) the sleeve cutter opening of the sleeve in the step (3) is aligned to all cutter openings of a muffs, and then the sleeve is set according to the seam allowance of 0.9 cm to 1.1 cm.

The combined oil pump for extracting oil includes large diameter oil pump, small-diameter annular valve type oil pump, oil pipe fixer, oil pumping rod, etc. The small-diameter annular valve type oil pump is connected with small oil pipe and its plunger is connected to the oil pumping rod, and the other end of the oil pumping rod is connected to the plunger of the large diameter oil pump. The liquid is pumped with the large oil pump to the annular space between the large and the oil pipes to form the second liquid surface, and the second surface has greater submergence depth than the natural oil deposit. The small pump has sucking port submerged inside the great submergence depth to pump the liquid to ground. The oil pumping rod and the oil pumping machine can bear the force produced by the small pump in raising the plunger, and the present invention can raise the liquid pumping amount in relatively low submergence depth.

The invention relates to a dyeing method for a yarn-dyed wool-like fabric. The dyeing method comprises the following steps: (1) adding an industrial liquid alkaline into a fabric to carry out alkaline decrement treatment; (2) adding a chelating agent GD-108, industrial glacial acetic acid and a disperse dye into the fabric subjected to the alkaline decrement treatment in the step (1) so as to dye the fabric; (3) adding industrial liquid alkaline and industrial sodium hydrosulfite for carrying out aftertreatment on the fabric dyed in the step (2); (4) shaping the fabric subjected to aftertreatment in the step (3); (5) adding an antistatic finishing agent and a soft anti-crease finishing agent for carrying out rolling liquid treatment on the fabric shaped in the step (4); and (6) decating the fabric subjected to rolling liquid treatment in the step (5) to obtain the yarn-dyed wool-like fabric. The dyeing method can be used for effectively improving the comprehensive color fastness of the yarn-dyed wool-like fabric, increasing the saturation degree of color and luster of the fabric, keeping the luster deep, enhancing the hand feeling of the fabric and better keeping the wool-like effect of the fabric; the fabric is bright in luster, flexible and fine in hand feeling; and the problem that a cloth surface is monotonous in color and has no luster because of decrement can be avoided.

A method for mowing Neonotonia Wightii (Wight&Arn.) Lackey cv. Tinaroo stage by stage and cultivating and utilizing harvested seeds includes the steps that area selection is performed; seedlings are grown; cultivation and utilization are performed in the current planting year; Neonotonia Wightii (Wight&Arn.) Lackey cv. Tinaroo is mown stage by stage and harvested seeds are cultivated and utilized since the second year; according to the stage-by-stage mowing of Neonotonia Wightii (Wight&Arn.) Lackey cv. Tinaroo and cultivation and utilization of the harvested seeds, since the second planting year, the Neonotonia Wightii (Wight&Arn.) Lackey cv. Tinaroo is mown once in July or August every year as forage grass, seeds are harvested from January to February every year since the third planting year, from the time when pods appear to the time before harvesting of the seeds, watering is performed once every 14 days to 16 days, and from the time after harvesting of the seeds to the time when the dry season is over, watering is performed once a month. With the method, the benefits of unit area of cultivation field are effectively increased, and the benefits of the unit area are increased by 566.45% annually compared with the situation that Neonotonia Wightii (Wight&Arn.) Lackey cv. Tinaroo is merely used as forage grass, two agricultural products including forage grass and seeds can be obtained in one growth cycle, and meanwhile soil fertility is improved.
