And the fire damper is convenient for further blocking flames and hot air flow so as to improve the fire retarding effect.

The utility model relates to a novel furnace end, including the fire cut seat and the fire cover, the fire cut seat is connected with the fire cover and forms the fire cut chamber, the fire cover includes the bottom ring part and the face shell part, is equipped with the connecting block between the bottom ring part and the face shell part, the connecting block is connected with the bottom ring part and the face shell part respectively and is fixed to make the bottom ring part and the face shell part form the gas outlet groove along the circumferential distribution between, the gas outlet groove is linked with the fire cut chamber, through setting the connecting block, can form the gas outlet groove on the fire cover, the fire cut chamber is even and sprays the gas outward through the gas outlet groove to the fire cover, thereby make the fire cover's fire effect more even, simultaneously, need not extra open multiple fire holes on the fire cover, has simplified the structure of the fire cover, makes the fire cover more beautiful.

The utility model relates to a novel furnace end which comprises a fire distributing seat and a fire cover, the fire distributing seat and the fire cover are connected to form a fire distributing cavity, a flow distributing piece is arranged at the position, corresponding to the position between the fire distributing seat and the fire cover, in the fire distributing cavity, the flow distributing piece is in an annular shape, and the fire distributing cavity forms an upper gas mixing layer and a lower gas mixing layer which are sequentially distributed from top to bottom through the flow distributing piece. The fire distribution base is provided with an air inlet, the flow distribution piece is tightly connected with the side, away from the air inlet, of the fire distribution cavity, the flow distribution piece and the side, close to the air inlet, of the fire distribution cavity form an air guide channel, and a first flow guide face capable of guiding airflow to flow from the side, away from the air inlet, of the fire distribution cavity to the side close to the air inlet is formed at the bottom of the flow distribution piece. The first flow guide face is of a continuous face-shaped structure without a perforated or hollowed-out area, the flow dividing piece can enable airflow to bypass in the lower gas mixing layer and then enter the upper gas mixing layer through the gas guide channel, and therefore gas in the upper gas mixing layer is distributed more evenly, and the better fire uniformizing effect is achieved.

The utility model discloses a combined firework with a double-layer composite effect, which comprises a combined firework whole body, the combined firework whole body is composed of a plurality of firework cylinders, the combined firework whole body is designed in an open screen shape, the firework cylinders are arranged in ten rows, and each row comprises thirteen firework cylinders. Two kinds of firework bullets are arranged in the whole combined firework, the same row of firework cylinders are filled with the same firework bullets, the firework bullets in every two adjacent rows of firework cylinders are different, row leads are arranged between every two adjacent firework cylinders in the same row, and surrounding leads are arranged between every two adjacent rows of firework cylinders. The combined firework with the double-layer composite effect is filled with two different firework bullets, the two firework bullets are alternately set off when the combined firework is set off, the set-off effects of the two firework bullets can be combined together in the mode, and compared with traditional fireworks, the combined firework is more ornamental, and meanwhile, the combined firework is safer compared with a traditional mode that the two fireworks are ignited and set off at the same time.

The invention discloses a fresh-keeping process of a freshly stewed donkey-hide gelatin composition with an effect of preventing excessive internal heat. The fresh-keeping process comprises the following steps: extracting; carrying out rough filtration and fine filtration on the combined decoction, and carrying out nanofiltration by adopting nanofiltration equipment; melting glue; performing stewing; performing filling; and a nano composite film is used for covering and sealing. According to the method, through compatibility of traditional Chinese medicinal materials and donkey-hide gelatin, discomfort caused by poor taste when part of people eat the donkey-hide gelatin is enhanced, dryness of the donkey-hide gelatin is relieved, the risk of getting inflamed after eating is reduced, and meanwhile, the donkey-hide gelatin has the effects of preserving moisture, tightening, resisting wrinkles, brightening, whitening and removing freckles. In addition, the traditional Chinese medicinal material extracting solution of the freshly stewed donkey-hide gelatin is purified and concentrated by adopting a nanofiltration technology, and the packaging is sealed by adopting a composite membrane, so that the shelf life of the product can be effectively prolonged.
