The invention discloses a dedusting system of a whole factory building, which comprises an air funnel, an air handling unit, a top air-return opening, an air supply pipeline and an air-return pipeline, wherein the air handling unit is arranged outside a workshop, the air funnel is arranged at the lower part of the inner side of the workshop, one end of the air supply pipeline is connected with the air funnel, and the other end of the air supply pipeline is connected with the air handling unit through the air supply pipeline; the top air-return opening is arranged at the top inside the workshop, one end of the air-return pipeline is connected with the top air-return opening and the other end of the air-return pipeline is connected with the air handling unit. The air supply direction of the air funnel is adjusted to change the air distribution of returned air, welding fume with higher temperature drifts upwards under the action of hot buoyancy, the fume further drifts upwards by the push of air sent out from the air funnel and does not move transversely, thereby the welding fume can be avoided from passing through the respiratory zone of the human body; and the fume and harmful gases are sucked into the air handling unit through the air-return pipeline under the suction action of the air-return opening at the top of the workshop and can not be directly removed outdoors, thereby the secondary pollution can not be caused.

The invention relates to urea-formaldehyde resin and a preparation method thereof. The urea-formaldehyde resin comprises the following components in parts by weight: 200 parts of formaldehyde solution, 120-170 parts of urea, 0-2 parts of polyvinyl alcohol, 1-10 parts of additive and 3-20 parts of extender, wherein the concentration of formaldehyde solution is 37%; in the preparation process, ureais added three or four times and the reaction is performed in weakly alkaline medium, weakly acidic medium and neutral medium in turn; and additive and extender are added in the synthesis of urea-formaldehyde resin. The urea-formaldehyde resin can be used in the production of the particleboard without being dewatered, thus the problems of wastewater discharge and environmental pollution can be solved and the production cost of the particleboard can be greatly reduced; and the urea-formaldehyde resin is suitable for various large, medium and small particieboard enterprises.

The invention discloses a formula and a preparation technology of a light fiber-reinforced thermoplastic resin composite sheet material with high flame resistance. The sheet material is composed of, 30-50% of reinforced fiber, 30-50% of thermoplastic resin fiber, 5-15% of halogen-free fire retardant powder and 5-15% of a bonding glue solution. The preparation technology comprises: weighing reinforced fiber and thermoplastic resin fiber according to the ratio, and performing preliminary mixing; utilizing a blower fan to convey reinforced fiber and thermoplastic fiber to a cotton storage bin; and utilizing the effect of free fall to enable fiber to be mixed fully, dispersed uniformly and the like. The light fiber-reinforced thermoplastic resin composite sheet material with high flame resistance has the advantages of simple production technology, low cost, excellent flame resistance and no obvious reduction on mechanical properties, is extremely applicable to fields of automotive trims, building decoration and the like, and has great practical value.

The invention discloses a yellow broiler feed containing chrysanthemum meal and a preparation method thereof. The preparation method comprises the following steps: smashing and evenly mixing raw materials including chrysanthemum meal, wheat bran, corn distilled grain, corn, bean pulp, cottonseed meal, rapeseed meal and the like; adding nutrition preparations, such as soya-bean oil, vitamin, aminoacid and the like, evenly mixing, and carrying out steam blending so that the raw powder is cured to a certain degree; and then, pelletizing to obtain a finished product. The yellow broiler feed containing chrysanthemum meal has the functions of improving carcass coloring effect of the yellow broiler and improving the sensuous performance of the yellow broiler product, the preparation method is simple, safe and reliable, and the growing vigour and the culture effect of the broiler are not affected.

The invention discloses dorking feed and a preparation method thereof. The dorking feed can be prepared by crushing and uniformly mixing wheat bran, distillers dried grains with soluble, maize, soybean meal, cotton dregs, rapeseed meal and other raw materials; adding disodium 5'-inosinate, disodium 5'-guanylate, methionine, threonine and other nutrition agents for uniformly mixing and then modulating by steam to cure cornstarch to a certain extent; and granulating to obtain the finished product. By using the invention, the content of the disodium 5'-inosinate in chicken can be improved and the edible flavor of the dorking can be improved. In addition, the method is simple, safe and reliable and cannot influence the growing vigor and the raising effect of the dorking.

The invention relates to a method for measuring a indicating diagram of an oil filed oil extractor without a load sensor, which comprises the following steps: the indicating diagram of an oil filed oil extractor is used for measuring and calculating a self machine of an oil extractor, a CPU controls the operating state of a transducer through a control unit, the transducer controls a main motor of the oil extractor according to signals transmitted by the CPU, one side of a balancing weight block of a crank device of the oil extractor is provided with a displacement sensor which can transmit a displacement signal to the CPU through a signal collecting unit, the operating data of the collection transducer are transmitted to the CPU, the CPU carries out coordinate treatment for the displacement signal and the operating data of the collection transducer to obtain a main motor indicating diagram, the CPU carries out vectorial resultant treatment for the main motor indicating diagram and the oil extractor indicating diagram to obtain a feed rod indicating diagram of an oil extractor feed rod, and the feed rod indicating diagram comprises displacement data and load data. In the invention, load sensors, pressure sensors, and the like do not need to be arranged on the oil extractor feed rod or a walking beam, and the like, and the invention can accurately and reliably measure the indicating diagram of the oil extractor without stopping unloading, and the like.

The invention discloses a piglet's mixed feed composition using dephenolized cottonseed protein. The piglet's mixed feed composition comprises the following raw materials by weight percent: 50-60 percent of corn, 6-15 percent of extruded corn, 3-8 percent of wheat bran, 8-15 percent of soybean meal, 6-10 percent of dephenolized cottonseed protein, 3-5 percent of fermented soybean meal, 0.6-1.2 percent of calcium hydrophosphate, 0.6-1.2 percent of stone powder, 0.10-0.50 percent of 98% lysine, 0.01-0.05 percent of methionine, 0.05-0.1 percent of choline chloride, 0.2-0.5 percent of salt and 1-1.5 percent of premix. The mixed feed is based on the normal corn and soybean meal type piglet's feed formula, and adopts 6-10 percent of dephenolized cottonseed protein to replace part of soybean meal to supplement part of synthetic amino acid without influencing the performance trait of piglets, and meanwhile, the weight gain cost of pork pigs is also lowered.
