The present invention aims for improving power load of a delivery pump and reducing absorbing resistance of a delivery pipe. When the delivery pump (3) of the fuel oil is used for delivering, a downflow pump (5) is kept to operate continuously, so that the high temperature oil form the downflow pump (5) is mixed and delivered to the fuel oil form a storage tank (1) and absorbed by the delivery pump (3) so that the viscosity of the fuel oil is reduced, and therefore the power load of the delivery pump (3) is improved, the delivery amount of the fuel oil form the storage tank (1) is reduced as much as the amount of the downflow oil, the delivery speed of the storage tank is reduced and the absorbing resistance is reduced.

The invention relates to a lean magnetite beneficiation method capable of reducing fineness of grinding ore, which comprises the following process steps: (1) finely grinding crushed lean magnetite ore and then carrying out primary coarse particle magnetic separation; (2) classifying primary coarse particle magnetic separation magnetic concentration by adopting a high frequency fine screen; (3) carrying out secondary ore grinding on oversize products and then carrying out secondary coarse particle magnetic separation; (4) returning secondary coarse particle magnetic separation magnetic concentration to the high frequency fine screen in step (2) to be reclassified, and repeating the operations of steps (2) to (6); (5) carrying out fine magnetic separation on high frequency undersize products; (6) carrying out fine separation on fine magnetic separation magnetic concentration by adopting a magnetic separation column so as to obtain iron ore concentration, returning magnetic separation column tailings to the secondary ore grinding procedure in step (3) and repeating the operations of steps (3) and (4). The granularity of -0.074 micrometers of iron ore concentration separated by the method disclosed by the invention accounts for 35-88%, which is reduced by more than 10% compared with iron ore concentration obtained by a conventional dressing production procedure, iron grade is 65-69%, and iron recovery rate is 45-97%.

The invention relates to a tracing and discriminating method for anti-counterfeiting information of a vehicle component. The method comprises the following steps that: a barcode intelligent terminal scans or inputs component barcode identifier information; the barcode intelligent terminal generates an XML-format file from the collected component barcode identifier information according to level binding relation, carries out encryption on the file to obtain a digital signature, and sends the digital signature to a vehicle information platform; the vehicle information platform queries whether the digital signature exists in the database of the vehicle information platform; if so, the component belongs to the original vehicle fittings; if not, the component does not belong to the original vehicle fittings; and the query result is fed back to the barcode intelligent terminal. According to the invention, authenticity identification and information query of the vehicle as well as the main components and parts of the vehicle for the consumers can be realized and thus the vehicle components can be prevented from being replaced; and a discriminating method for malicious claims beyond the warranty and the fraud of the vehicle with warranty can be provided.

A scrub brush-sponge includes a base provided with a recessed peripheral lip, which has a plurality of attenuated regions configured to minimize the resistance of the base to external bending forces, and a sponge coupled to the base and made from polymeric material, which may have as low a PPI as 10. The sponge is configured so that it can effectively surround at least a substantial peripheral portion of instruments or portions to be treated with fluid, which is contained within the sponge, without applying substantial external forces to the base. A flexible layer made of woven or non-woven bonded polymeric fibers is on a scrubbing surface of the sponge and provides an enhanced scrubbing feature. An abrasive may be included on the flexible layer to further enhance the scrubbing feature.

A tufting machine of novel structure which can produce a pile fabric mixing both a cut pile and a loop pile through a simple arrangement. Means (106, 108) for displacing a finger plate (98) in the piercing direction of a needle (30) through a foundation (12) are provided so that the capturing state of a loop (114) formed on the surface (29) of the foundation (12) by a looper (84) can be released by displacing the finger plate (98) with the displacing means (106, 108) to allow displacement of the finger plate (98) to the surface side of the foundation (12). A loop captured by the loop (114) is cut into a cut pile by means of a knife, and the released loop is not cut but becomes a loop pile.

The invention discloses a method for preventing air release valves of a double-hearth kiln from spraying ash. The method comprises the following steps as follows: A, when a system cuts off conveying coal gas to the kiln, an electric control valve is opened to convey the gas in the kiln to a dust remover, and the pressure in the kiln is reduced to 10kpa or lower before entering a reversing period;B, blowing is conducted on a dust removal cloth bag once per hour; C, during reversing, a combustion-supporting air release valve is opened for 3 seconds, and then a cooling air release valve is opened; D, raw material granularity control is conducted; and E, the opening and closing action time of each valve is adjusted to be 4-5 seconds by adopting a mode of feeding during combustion. Compared with the prior art, during reversing of the kiln, the gas in the kiln is released to the dust remover in advance, dust sprayed out of the combustion-supporting air release valve is recycled, the pressure in the kiln is reduced through technological operation improvement and other means, and the ash spraying phenomenon generated by the combustion-supporting air release valve and the cooling air release valve is prevented.

The invention discloses a cut tobacco additive which can reduce the CO in the smoke gas.
