The invention discloses a preparation method of reflective heat-insulation ceramic glazed tiles. The preparation method includes mixing frit raw materials, and founding the frit raw materials in a frit furnace into frits at a founding temperature of 1400-1600 DEG C until the raw materials fuse completely; mixing the frits with a raw material with grinding to obtain glaze slip, wherein the frits account for 10-100% of the total mass of the raw materials, and the content of titanium dioxide in the glaze slip is not lower than 8% of the total mass; applying the glaze slip on green bodies; drying the green bodies with the glaze slip, and firing at a temperature of 1100-1250 DEG C so as to obtain the reflective heat-insulation ceramic glazed tiles. The preparation method has the advantages that the frits are mixed with a specific amount of raw material, and enamel layers with titanite crystals as a main crystal phase are formed on the surfaces of the ceramic glazed tiles and are capable of reflecting sunlight reflectively, so that absorption of the ceramic glazed tiles for solar heat radiation can be reduced effectively, and building energy consumption of hot-summer and warm-winter regions is reduced remarkably; the preparation method is low in preparation cost and remarkable in energy-saving and environment-friendly effects.

The invention discloses an anti-theft and moisture-proof method which comprises an anti-theft method and a moisture-proof method. When a thief steals a charging pile, the thief needs to open an anti-theft air outlet cover upwards to unscrew foundation bolts so as to steal the charging pile. When the thief lifts the anti-theft air outlet cover upwards, a lower electroconductive plate moves upwardsto push and press against an upper electroconductive plate under the action of return springs, and thus an alarm circuit is closed. The moisture-proof method comprises a constant-temperature method and a constant-humidity method. The constant-temperature method and the constant-humidity method are alternative methods. The anti-theft and moisture-proof method for the charging pile can keep the airin the charging pile clean and keep the dust less, so that the temperature and humidity in the charging pile can be kept in an optimal range for a long time. Specifically, the relative humidity in thecharging pile should be controlled between 45% and 75% and the temperature should be controlled between 18 DEG C and 25 DEG C, so that the working stability of the charging pile is greatly improved,the service life of the charging pile is greatly prolonged, the user experience of charging electric vehicles is improved, the cost for long-time use is reduced, and the rapid development of the electric vehicles is provided with corresponding assistance.

The invention relates to a building formwork, which comprises surface formwork units and a frame structure, wherein the surface formwork units are paved on the surface of the frame structure; connecting ribs are respectively arranged on two sides along a longitudinal direction of formwork bodies of the surface formwork units; a bulge is arranged on the connecting rib on one side; a slot is correspondingly formed on the connecting rib on the other side; reinforcing ribs are arranged along the longitudinal direction of the formwork bodies; the reinforcing ribs and the connecting ribs are located on the same sides of the surface formwork units; the frame structure comprises a longitudinal connecting rod and a lateral connecting rod; the longitudinal connecting rod is arranged on the lateral connecting rod; the surface formwork units are arranged on the surface of the longitudinal connecting rod; the longitudinal connecting rod is at least locally embedded between the reinforcing ribs and / or between the reinforcing ribs and the connecting ribs of the surface formwork units; and adjacent surface formwork units are tightly connected to each other by the correspondingly arranged bulge and slot on the connecting ribs and are fastened by a U-shaped buckle. The building formwork has the advantages of less steel usage, high practicability, high splicing efficiency, easiness in operation, economical and environmentally-friendly properties, excellent stability and evenness, capability of effectively preventing slurry leakage, and wide market prospect.

The invention discloses an oil sludge separating device. The oil sludge separating device comprises an oil sludge pond, a first pump body, a vibrating screen, a first storage tank, a second pump body, a centrifugal machine, a second storage tank and a third pump body which are communicated with one another in sequence. Oil sludge is fed into the vibrating screen from the oil sludge pond through the first pump body for primary separation. A solid-phase object after primary separation is conveyed out, a liquid-phase object after primary separation enters the first storage tank to be deposited, and the deposited liquid-phase object is fed into the centrifugal machine through the second pump body for secondary separation. A solid-phase object after secondary separation is conveyed out, and a liquid-phase object after secondary separation enters the second storage tank. A density tester is arranged in the second storage tank, and a qualified liquid-phase object detected by the density tester is conveyed through the third pump body. The oil sludge separating device provided by the invention can improve the separating efficiency.

The invention provides a detection device and method for observation and measurement of the inner wall of a deep hole. The method comprises the steps that a clamping device (1) on an upper workbench (2) clamps a deep hole test piece; and a horizontal axis microdrum (3), a vertical axis microdrum (5), an elevating handle (8) and an angle adjusting turn button (10) are adjusted so that light of a spot light source (12) is input to the visual field of a stereomicroscope (13) from the bottom of the deep hole test piece and upwardly through the deep hole test piece. Thus, a clear visual field of high field depth can be obtained, and the inner wall of the deep hole test piece can be observed and measured in multiple angles.

The invention discloses a disposable combinational membrane module which is composed of combinational joints, hollow fiber membrane yarns and a membrane shell, wherein the combinational joints are arranged at the two ends of the disposable combinational membrane module, and the hollow fiber membrane yarns are arranged in the middle of the disposable combinational membrane module; the combinational joints comprise an upper combinational joint and a lower combinational joint, the lower combinational joint is provided with an aeration device, a casting head part is cast in a way of partitioned casting, and aeration discs are uniformly distributed in each casting interval, so that membrane bundle yarns in a membrane pipe fitting are uniformly distributed, and poor water-passing and aeration cleaning effects are not caused when the membrane bundle yarns are distributed excessively densely. In the disposable combined membrane module, disposable parts comprise a membrane connector, a membrane casting head and a membrane pipe, namely, when a membrane runs to a certain time or the membrane is contaminated and blocked seriously and can not reach requirements after being cleaned, a mode of directly replacing the membrane connector, the membrane casting head and the membrane pipe is adopted in the invention and the mode is more economic and environmental-friendly as compared with the traditional mode of replacing a whole membrane module; and after a membrane stack is formed, only an operation of connecting ports of a whole stack of membrane devices with a main water inlet pipe and a main water outlet pipe is required to be performed, so that the filling density is greatly improved, space can be saved and a lot of pipe fittings are also saved.
