The invention relates to a preparation method for fruit tree nutrition liquid, in particular to a preparation method for the fruit tree nutrition liquid containing biochemical humic acid. The method comprises the following steps: dissolving amino acid in a proper amount of water; adding ferrous sulfate into liquid in the step I to form complex iron; gradually adding the rest raw materials in the step II and fully dissolving all the rest raw materials; adjusting the pH value of supernatant liquid containing biochemical humic acid to be 6-7; adding 20% by weight of the adjusted supernatant liquid containing biochemical humic acid in the step III; adding distilled water into a prepared solution until a required amount of the solution is obtained, and adjusting the pH value to be 2-3 by citric acid to obtain the finished fruit tree nutrition liquid. The fruit tree nutrition liquid provided by the invention can comprehensively provide nutrition for fruit tree growth, stimulate fruit tree growth, and improve fertilizer efficiency, adverse resistance of fruit trees and fruit quality.

The invention discloses a water quantity adjustable type water falling device. The water quantity adjustable type water falling device comprises a water leaking disk, a speed regulating disk, a hose,a water guide pipe, a main pipeline, a sealing sleeve, a spring sleeve, a third sleeve, a second sleeve and a first sleeve; the speed regulating disk is mounted in a groove in the water leaking disk;the water leaking disk is communicated with the water guide pipe through the hose; the tail end of the water guide pipe is communicated with the main pipeline; the spring sleeve is mounted at the bottom of the sealing sleeve; the third sleeve, the second sleeve and the first sleeve are connected to and mounted at the top end of the spring sleeve from bottom to top in a sleeving manner. The devicedesign is suitable for mounting of kitchen sinks, the water leaking disk can realize that water can flow out, a leaking net is arranged in the water leaking disk, impurities can be filtered, blockingsheet design of the speed regulating disk can block the water quantity of a water outlet of the water leaking disk, and the flowing speed can be adjusted; when water exists in the basin, the self weight of water presses down the water leaking disk, the journey of the three sleeves is shortened, the water leaking disk falls off, the water speed is increased; when the water quantity is reduced, thejourney of the three sleeves is lengthened, the water falling device is blocked.

The invention relates to a water cooling device, and provides an anti-oxidation water cooling device for high-temperature easily oxidized powder, which includes a powder dispersing conveying device and a cooling tower body; the powder dispersing conveying device includes a feeding pipe and a dispersing conveying pipe and the nozzle; one end of the dispersing conveying pipe is connected with the cooling tower body, and the other end of the dispersing conveying pipe is provided with a nozzle; the dispersing conveying pipe is connected with the feeding pipe to form a three-way structure. Also provided are a magnetization roasting system including the anti-oxidation water cooling device for the high-temperature easily oxidizable powder, and an anti-oxidation water-cooling method for the high-temperature easily oxidizable powder. The invention realizes the water quenching cooling of high-temperature easily oxidizable powder, solves the problem of a large amount of water vapor gathering during water quenching, and realizes the transportation of the mixed flow of water and powder. The device has low manufacturing and operating costs and a large processing capacity. Conducive to large-scale production.

A water saving valve is fitted to a hose or a water pipe and mixes air bubbles with water. Water receiving flask part 18 receives tap water from a water pipe 12. Tapered hole part 20 has a flow path whose cross-sectional area is gradually reduced from the upstream side toward the downstream side. Conduit part 32 has a large diameter section 56 and a small diameter section 57. The large diameter section 56 is linked to the tapered hole part 20. The conduit part 32 has a flow path 38 at an axial part thereof whose cross-sectional area is substantially uniform. The large diameter section 56 has an air suction port 30 running through from the flow path 38 of the axial section to the outer peripheral surface. A check valve 64 is inserted into the air suction port 30. Sleeve 50 is rigidly secured to the conduit part 32 by a support body 44 arranged at part of axial hole 90. The sleeve 50 has an eaves-like section 46. The eaves-like section 46 surrounds the outer peripheral surface of the large diameter section 56 with a gap 48 interposed between them. The sleeve 50 surrounds the periphery of the other end of the conduit part 32 with a space interposed between them. Air is sucked in from the gap 48 through the air suction port 30 so that water does not leak if hydraulic pressure is applied in the opposite direction.

The invention discloses a penetration-type wire mesh dust-collection pole. The penetration-type wire mesh dust-collection pole comprises dust-collection anode plates, a dust-collection framework and a water distribution device. The dust-collection anode plates are fixed to the dust-collection framework. The dust-collection anode plates are wire mesh plates and are fixed to the outer side of at least plane of the dust-collection framework. Metal plates are arranged on other sides of the dust-collection framework. The dust-collection anode plates and the metal plates are connected and surround the dust-collection framework to form a tank. The water distribution device is arranged in the tank and is used for feeding water into the tank. The invention also discloses a wet-type electric deduster with the wire mesh plates. The wire mesh plates are used as the dust-collection anode plates so that the problem that an electrode plate of the existing wet-type electric deduster forms all-area uniform water film difficultly and local dry spots and severe local back corona are formed is solved; dust accumulated on an electrode plate is fully and ideally removed; equipment is simple; and reconstruction and construction costs are low.

The invention discloses a combined river channel gate and a water control method thereof. The combined gate includes water retaining walls arranged on both sides of the river channel, and the river channel water retaining wall is a reinforced concrete wall. The invention cleverly arranges a herringbone gate mechanism, wherein The two gate plates are arranged in a herringbone shape, and the adjacent side ends of the two gate plates are provided with abutting mother plates and abutting sub-plates, which form a herringbone vertex and face upstream of the river; Under the action of the pressure, the structure self-locking is realized, which greatly improves the safety of the gate. In addition, the abutment mother board and the abutment sub-board forming the herringbone vertex are in contact with each other, and an elastic stop is arranged between the abutment mother board and the abutment sub-board. The water rubber pad improves the sealing performance of the gate, and at the same time, the elastic water-stop rubber pad plays a buffer role in the collision process between the abutting motherboard and the abutting sub-board; meanwhile, the vertical multi-row arrangement of the herringbone gate mechanism facilitates the control of water discharge according to needs Or store water, can form waterfall landscape after opening in addition or water store overflows when overflowing.
