The invention discloses a method for preparing organic fertilizer by using sewage to treat excess sludge, which comprises the following steps of: (1) sludge acidification and slurry adjustment; (2) heating treatment; (3) filtration and washing; (4) neutralizing treatment of mud cakes; and (5) preparation of the organic fertilizer with the mud cakes, namely granulating the mud cakes and drying andpacking the granules to prepare the organic fertilizer. The method has the advantages that: (1) the method removes heavy metals from the sludge, can ensure the use safety of the organic fertilizer prepared by using the sludge in agricultural production, eliminates the environmental risk of sludge recycle, and creates preconditions for large-scale agricultural utilization of the sludge; and (2) N,P and K contained in the sludge are necessary nutrient substances for crop growth, the organic fertilizer produced by using the sludge from which the heavy metals are removed belongs to a green product, ...

Collision protection device of quartzite piezoelectric sprayer

The invention provides a collision protection device of a quartz piezoelectric spray head. The device comprises a shell (1), a collision terminal (2) and a telescopic assembly (3) used for driving the spray head to move. The shell is provided with a guide groove (4), a fixing ring (10) and a sealing cover (11), the collision terminal comprises a collision head (12), an indexing claw (5) and a tail groove (7), and the telescopic assembly (3) comprises a sliding claw (6), a spring (8) and a connecting piece (9). The problem that in existing on-demand titration ink-jet equipment, a quartziferous spray head is prone to collision and breakage is solved, the quartziferous spray head is protected, a telescopic device is additionally arranged on the basis of a collision terminal, in the initial stage of collision, a spring absorbs part of collision energy, and when the collision stroke reaches a certain degree, the spray head is retracted into a protection device shell, so that the anti-collision ...

Process for processing magnolia officinalis based on method of steaming with rhizoma zingiberis recens juice

The invention discloses a process for processing magnolia officinalis based on a method of steaming with rhizoma zingiberis recens juice. According to the process, the processed magnolia officinalis is obtained according to the steps of removing impurities and coarse peels of magnolia officinalis to be processed, cleanly washing, soaking, shredding, drying the shreds in a hot air circulating oven, uniformly mixing with ginger juice, then steaming in a steamer for 1-8 hours, subsequently drying in the oven till no moisture exists and finally cooling. Compared with the classic method of stir-baking with rhizoma zingiberis recens juice, the total of magnolol and honokiol of the processed magnolia officinalis prepared according to the process can reach 2.5 percent, the variation range is small, the production conditions are easily standardized, so that the process solves the problem of environment pollution caused by heavy smoke and dust during production of the processed magnolia officinalis ...

Anti-vibration impact heat dissipation method for LTCC (Low Temperature Co-Fired Ceramic) substrate

The invention mainly relates to an LTCC (Low Temperature Co-Fired Ceramic) substrate anti-vibration impact heat dissipation method which comprises a vibration reduction heat dissipation cover plate, and a heat dissipation clamping cover plate is mainly composed of an upper heat dissipation flow channel (1), an upper vibration reduction cover plate (2), a lower heat dissipation flow channel (6) and a lower vibration reduction cover plate (5) and comprises heat conduction silicone grease (3) and an LTCC substrate (4). S-shaped heat dissipation flow channels are arranged in the upper heat dissipation cover plate and the lower heat dissipation cover plate, so that heat emitted by elements in the LTCC substrate during service can be effectively taken away. The LTCC substrate is clamped and fixed in the groove of the lower vibration reduction cover plate, and a layer of heat conduction silicone grease is arranged between the LTCC substrate and the clamping device, so that the heat exchange efficiency ...

Small-angle full penetration welding method for extra-thick plate

The invention discloses a small-angle full penetration welding method for an extra-thick plate. The thickness of the welded extra-thick plate is larger than or equal to 50 cm; gaps are reserved between the welding plates, and large-included-angle and small-included-angle double-face welding seam welding is formed on the two sides; the large-included-angle side is machined into a J-shaped groove through carbon arc air gouging, then a ceramic gasket is pasted, the small-included-angle side is welded firstly, then the large-included-angle side is welded, and flat-position multi-pass full-length welding is adopted in weld joint welding. According to the small-angle full penetration welding method for the extra-thick plates, gaps are reserved between welding plates, and a double-face welding structure is adopted; pasting a ceramic gasket on the large-included-angle side, firstly welding the small-included-angle side, and then welding the large-included-angle side; and welding seam welding adopts ...
