Provided are a water heater pipeline anti-freezing control method and system and a water heater. The method includes acquiring environment temperature and water temperature and water level of a water tank of the water heater; comparing the environment temperature and the preset environment temperature; when the environment temperature is lower than the preset environment temperature, executing the circulation heating water producing mode where water in a water inlet pipe and a water outlet pipe of the water heater flows in a circulation mode according to the water temperature and the water level of the water tank of the water heater; when the water heater is applied under the condition that the environment temperature is lower than the preset environment temperature, entering the circulation heating water producing mode enabling the water in the water inlet pipe and the water outlet pipe of the water heater to flow in the circulation mode. Flowing water passes through both the cold water inlet pipe and the circulation water inlet pipe of the water heater, the requirement for hot water usage can be met, and the pipeline has no freezing risks.

The invention provides a profile combination frame for a silo and a method for making a vertical shaft structure silo, belonging to the field of storage equipment, including a template assembly, an operation platform assembly, a hydraulic lifting assembly and a maintenance assembly. The hydraulic lifting assembly is used for For the lifting of the formwork assembly, the operation platform assembly includes an inner platform and an outer platform, which are used for operators or equipment to bind steel bars, pour concrete or place control equipment. The inner platform is arranged on the inner circle of the template assembly, and the outer platform On the outer ring of the formwork assembly, the curing assembly is arranged at the lower end of the outer platform, and water is sprayed outward to maintain the concrete. The invention improves work efficiency and reduces construction risk, adopts thin iron plates welded into inverted cones for overall construction, ensures the safety of the overall load-bearing support of the cone bucket construction, and makes the cone bucket appearance achieve the effect of fair-faced concrete.

The invention relates to a corn multifunctional soil-improving and nutrient-control-released fertilizer, which comprises a biocarbon soil improving material and a chemical fertilizer according to a weight ratio of (13%-17%):(83%-87%). The fertilizer is prepared by combining the biocarbon soil improving material and the chemical fertilizer together according to the weight ratio mentioned above, thus the nutrients in chemical fertilizer can be fully utilized, at the same time, the soil can be improved, and the nutrients can be control-released. Moreover, the fertilizer can prominently increase the content of organic carbon in soil, improve the soil property, and reduce the releasing speed of nutrients, thus the happening rate of farmland pollution is reduced, the nutrient utilization rate is improved, the crop output and the income of farmers are increased, and the effect on corns is the most prominent.

The invention discloses a method for transporting asphalt mixture for expressway, which comprises the steps of counting the number of transport vehicles, determining the traveling route, preheating the transport vehicles, spraying lubricant, loading, heat preservation, transportation, cleaning and the like. The number of transport vehicles is determined according to the production capacity, transportation time and consumption of the mixing plant, and additional safety reserve vehicles can avoid paving material breakage. Measures such as preheating of the transport vehicle, spraying lubricant and heat preservation can minimize the probability of segregation of the asphalt mixture, improve the quality of the asphalt mixture, improve the quality of the asphalt pavement, prolong the service life of the pavement and reduce the maintenance cost in the later period effect.

The invention provides a cooling and conveying device, and belongs to the technical field of conveying devices. The cooling and conveying device comprises a tank, a spindle, a driving mechanism, a feed inlet, a discharge outlet and a cooling mechanism. Advancing blades are intermittently arranged on the spindle and comprise cavity matrixes and spiral blades, the spiral blades are arranged on the cavity matrixes, the cooling mechanism comprises a water inlet pipe, communicating pipes and a water outlet pipe, the water inlet pipe, the communicating pipes and the water outlet pipe are arranged in the spindle, and the water inlet pipe, the cavity matrixes and the water outlet pipe are sequentially communicated with one another via the communicating pipes. The cooling and conveying device has the advantages that the cooling and conveying device is novel in structure and reasonable in design and can be applied to mixing, conveying and cooling expanded ammonium nitrate explosive, the expanded ammonium nitrate explosive can be sufficiently mixed, products are good in free-running property and stable in quality, and good cooling effects can be realized.

The invention discloses a fertilizer water irrigation system relating to the technical field of garden irrigation. The fertilizer water irrigation system comprises a water pump, a reservoir, an irrigation pipeline, an irrigation terminal, a detection system and power generation equipment, wherein the detection system comprises an acquisition terminal and a control center; the detection system is provided with multiple acquisition terminals in a plant root detection area; the control center receives a signal of the acquisition terminal and judges the needs of plants according to the signal; after the control center receives a signal instruction of a user terminal, the signal is transmitted, a water pump I pumps water into the reservoir through a pipeline, and the control center simultaneously transmits the signal to a fertilizer metering system; after the control center receives a fertilizer water data signal, a water pump II pumps the fertilizer water mixed in the reservoir to the irrigation terminal through a pipeline. According to the fertilizer water irrigation system provided by the invention, the irrigation efficiency can be effectively improved, the amount of water and fertilizers needed in the planting area is met in real time by reasonably controlling the irrigation amount and irrigation time, and remote control can be realized.

The invention belongs to the technical field of veterinary chemical medicinal preparations, and particularly relates to a dimetridazole soluble powder and a preparation method thereof. The dimetridazole soluble powder is prepared from the following components in parts by weight: 18-22 parts of dimetridazole and 10-15 parts of hydrophilic carrier, and the balance of glucosum anhydricum or lactose anhydrous supplemented to 100 percent, wherein the hydrophilic carrier is one or more of PVP K30, poloxamer 188 and sodium lauryl sulfate. According to the dimetridazole soluble powder, the specific surface area of an insoluble medicine can be improved, and the wetting property can be increased, so that solubility of dimetridazole can be improved, the dissolving time is shortened, and the aim of clinical drinking water administration can be achieved. The dimetridazole has good bioavailability and good medicinal effect.
