Therefore, the loosening effect of soil is enhanced, and the tillage depth and quality are improved.

This invention provides a method and application for the ecological restoration of rock mine slopes in ecologically fragile high-altitude areas, specifically relating to the field of ecological environment restoration technology. The ecological restoration method includes: leveling the rock mine slope in an ecologically fragile high-altitude area, then restoring the slope's topography by covering it with topsoil; constructing a masonry diamond-shaped grid structure for protection on the rock mine slope, planting native shrubs and grasses within the grid; installing an integrated water and fertilizer drip irrigation system on the rock mine slope; and finally, applying sprayed concrete or constructing slope supports to prevent soil erosion on the slope surface; wherein the altitude of the high-altitude area is >4000m. This ecological restoration method provides strong technical support for the ecological restoration of rock mine slopes in ecologically fragile high-altitude areas, and also provides important guarantees and references for ecological restoration work after mining in high-altitude regions.

The invention relates to the technical field of vacuum evaporation equipment, in particular to an anti-sputtering mechanism for a condenser pipe of a vacuum evaporator, which comprises a shell and a condenser pipe fixedly mounted on the inner wall of the shell, a baffle is fixedly mounted at the position of the condenser pipe in the shell, and a guide plate is further fixedly mounted on the inner wall of the shell. And a drainage mechanism is arranged between the flow guide plate and the shell and is used for discharging condensate water in real time. The baffle, the flow guide plate and the drainage mechanism are arranged on the periphery of the condensation pipe, the baffle forms a barrier, metal steam can smoothly pass through and fully exchanges heat with the condensation pipe, meanwhile, liquid drops and impurities splashed from the surface of the condensation pipe during vacuum removal can be effectively blocked, and therefore the risk that products are polluted is greatly reduced. The condensate water can be rapidly collected into the drainage mechanism through the guide plate, rapid collection and drainage of the condensate water are achieved, and the influence of the condensate water on follow-up vacuumizing is avoided.

The invention discloses a control method of a calcium-based desulfurization system for coke charging dedusting flue gas of a dry quenching furnace, and belongs to the technical field of coking flue gas purification. The method comprises the following steps: monitoring the flue gas sulfur dioxide concentration in real time, and starting a calcium spraying system in an interlocking manner when a threshold value is reached; by controlling the calcium spraying time, the arrival time (T2) of the desulfurizing agent is smaller than or equal to the flowing time (T1) of the flue gas from the monitoring point to the spraying point, so that accurate and synchronous mixing is realized; according to the real-time flue gas flow and SO2 concentration, the calcium spraying amount is dynamically controlled in an interlocking mode, and the calcium-sulfur ratio is maintained to be 1.8-2.4; intelligent ash removal control based on single-bin or total pressure difference triggering is adopted for the bag type dust collector, and ash removal is executed by staggering coke charging operation time periods of the dry quenching furnace according to set intervals. According to the invention, through cooperative intelligent control of time sequence, dosage and ash removal, the problems of desulfurization agent waste, excessive emission and unstable system operation under the intermittent fluctuation flue gas working condition of dry quenching are solved, and efficient desulfurization, resource saving and reliable system operation are realized.

This utility model provides an integrated corn planting and mulching machine, relating to the field of corn planting technology. It includes a vehicle body with wheels at its four corners; a planting component located on the right side of the vehicle body's top for planting corn; and an irrigation and fertilization mechanism located at the center of the vehicle body's top, comprising a storage tank, a driving and stirring unit, and a spraying unit. The driving and stirring unit stirs the mixed solution inside the storage tank and sprays it onto the soil after planting. By integrating the planting component, irrigation and fertilization mechanism, mulching mechanism, and tension control mechanism into the vehicle body, the entire corn planting process from planting to mulching is integrated. The winding component and the driving and rotating unit are connected by bolts, eliminating the cumbersome process of disassembling bolts with tools as in traditional patents. Operators can directly disassemble and assemble the winding component, significantly shortening the single-roll film replacement time and effectively improving the equipment's continuous operation capability.

The invention discloses a method for removing oxalic acid and salts thereof in wastewater by using hydrogen peroxide. The method comprises the following steps: pretreating wastewater containing oxalic acid and salts thereof, and adjusting the pH value to 3.5-4.0; adding hydrogen peroxide into the adjusted wastewater, and uniformly stirring to obtain mixed wastewater; and feeding the mixed wastewater into an activated carbon reaction column in a pulse water feeding manner, and removing oxalic acid and salts thereof in the water. According to the method, the removal efficiency of oxalic acid is effectively improved, and compared with the prior art, the method has the advantages that the process is simple, secondary pollution is avoided, and the wastewater treatment efficiency and environmental friendliness are greatly improved.

This application relates to the field of materials science and engineering, specifically disclosing a method for producing a balanced high-potassium, fully water-soluble compound fertilizer based on a high-tower process. The method includes raw material preparation, melt mixing, granulation, cooling and sieving, and finished product coating steps. This invention innovatively uses 304 austenitic stainless steel in all material contact stages, eliminating rust contamination at the source. It employs a double-layer coating process—first spraying hydrophobic oil, then applying fine powder—for surface modification. Combined with optimized melt shearing and stepped cooling parameters, the prepared compound fertilizer exhibits excellent properties such as full water solubility, no residue, high strength, and resistance to caking during storage and transportation. This invention effectively solves the problems of high water-insoluble matter and easy hygroscopic pulverization in traditional high-tower products, is fully compatible with integrated fertigation drip irrigation systems, and significantly reduces production energy consumption.
