The invention discloses a vacuum low-temperature drying method for bovine bone glue, which comprises the following steps: 1) raw material preparation step: loading the concentrated bovine bone glue extract into a container, wherein the volume of the concentrated bovine bone glue extract is V1, and the container The volume is V2, V1: V2≤20%; 2) vacuum drying step: first the container of step 1) is put into microwave vacuum drying equipment and heated, so that the bovine bone glue extract concentrate is in a low-temperature boiling state; water vapor and The acetic acid vapor is sucked away by a vacuum pump, and the bovine bone glue extract is concentrated and dried to obtain the bovine bone glue. The vacuum low-temperature drying method of the invention has the characteristics of low acetic acid content, low energy consumption, short drying time, high product yield and high production efficiency.

The invention discloses a method for sewage reutilization. The method comprises: conveying sewage from vegetable washing, and sewage from tooth brushing, face washing and hair washing into a filtering instrument for filtering through a pipeline, and conveying the filtered water into the water tank of a closestool so as to realize sewage reutilization. The method and device of the invention can filter some available sewage simply and precipitate the sewage, then use clarified water in closestool flushing, or watering of flowers and mopping, thus effectively reducing the use of water resources. And the device provided in the invention has automatic water storing and automatic draining functions, has no need for manual operation and for worrying about overflow phenomenon, thus being very human-friendly.

The invention relates to the technical field of football cleaning, in particular to a high-efficiency scrubbing and drying device for footballs used in competitions. The technical problem to be solved by the present invention is that it is difficult to clean the seams of the skin by manual scrubbing, the cleaning effect is poor, and the water consumption is easy to increase. In order to solve the above-mentioned technical problems, the present invention provides a high-efficiency scrubbing and drying device for soccer balls used in competitions. The present invention consists of a coarse cleaning mechanism outside the box and a cleaning mechanism inside the box. The football is initially cleaned by airflow, which facilitates subsequent cleaning. , effectively reduces cleaning water, is more environmentally friendly, improves the frequency and intensity of football activities in the cleaning box, and further improves the effect of rinsing by bumping the football against each other and the cleaning box, and can effectively remove the stains in the seams of its skin Vibrating out, at the same time, it can also remove water by bumping and rolling the football. The wind rough cleaning process is incorporated into the cleaning box, and the high-speed airflow is effectively used to further remove the moisture on the surface of the football.

The invention relates to a breeding wastewater treatment process, which specifically includes the following process: S1. The breeding wastewater is collected into a sediment tank through a sewage pipe, and the solid feces residue is removed through a solid-liquid separator, and the liquid enters a black film biogas tank; S2. The water flow well measures the influent water entering the black film biogas digester, and distributes the water to the black film biogas digester to remove organic matter in the water; S3, the biogas slurry generated by the black film biogas digester is distributed to the algae purification tank through the lift pump, and put into the immobilized algae The reaction group removes nitrogen, phosphorus nutrients, heavy metals and refractory organic matter in the water body; S4, the effluent from the algae purification tank enters the intermediate sedimentation tank, realizes the separation of algae and water according to the action of gravity, and the sediment flows back to the algae purification tank; S5, the intermediate sedimentation tank The effluent water enters the aerated biological tank, and a microbial generator is installed in the tank to rapidly degrade the organic matter and biochemical sludge in the water through the generated microbial flora; S6, the clarified water from the aerated biological tank enters the storage tank.

The present invention provides a sensor cleaning method, a device, an unmanned vehicle for mining, and a readable storage medium, which are applied to the unmanned vehicle for mining. equal to the preset value; when it is determined that the dirt detection value is greater than or equal to the preset value, control the mining unmanned vehicle to decelerate to stop, and detect the current rainfall; The sensor is cleaned by preset cleaning logic corresponding to the rainfall. In the sensor cleaning method of the present invention, after the unmanned mining vehicle detects that the contamination detection value of the sensor reaches the preset value, it can stop driving to perform rainfall detection, and then select the corresponding cleaning logic in combination with the rainfall to clean the sensor, thereby Improve the efficiency of sensor self-cleaning and save cleaning water.
