And a mixing structure is arranged in the cleaning pool body. The water supply system moves along the cleaning pool set and provides clean water for the corresponding cleaning pool bodies. And a liquid level sensor is arranged in the cleaning pool body. The multiple cleaning pool bodies are sequentially arranged in a stepped mode, so that water in the previous cleaning pool body enters the next cleaning pool body. The method has the remarkable advantages of improving the cleaning effect, accurately controlling the water quality, flexibly managing the water flow, saving energy, protecting the environment and the like.

The application discloses a shotcrete rebound-reducing agent and a preparation method thereof. The shotcrete rebound-reducing agent is prepared from the following raw materials in mass percentage: 15-30% of a quick-setting component, 2-5% of a viscosity-increasing component, 10-15% of a reinforcing component, 2-5% of an anti-freezing component, 1-4% of a stabilizer, and the rest of water; and the viscosity-increasing component is a combination of polyvinylpyrrolidone and modified carboxymethyl cellulose. The prepared shotcrete rebound-reducing agent has the advantages of good sprayability, high hourly strength, good anti-freezing and stability, and the like, can improve the working performance of shotcrete, reduce the content of a quick-setting agent and significantly reduce the rebound rate of shotcrete, and has good economic benefits.

Each independent water storage unit (21) and a through water flowing channel (22) are arranged in the protection pipe (2). The safety guarantee effect is lasting and effective, and the risk resistance of a bridge system is improved.

This invention relates to a multifunctional electric steam drum water level measurement system, comprising a steam-water separation system, a liquid level detection system, a wastewater discharge system, a water supply system, and a control system. The liquid level detection system is connected to both the steam-water separation system and the water supply system. The wastewater discharge system is connected to both the steam-water separation system and the liquid level detection system. All three systems are electrically connected to the control system. The steam-water separation system separates steam and water, ensuring water supply in the circulation loop and providing qualified steam. The liquid level detection system detects the steam drum water level. The wastewater discharge system collects wastewater generated during long-term system operation. The water supply system replenishes the water level in the liquid level detection system. The control system controls the operation of the steam-water separation system, the liquid level detection system, the wastewater discharge system, and the water supply system through automatic calibration, wastewater discharge and cleaning, detection, and water replenishment control commands.

The utility model provides a kind of pineapple planting watering device, it is related to agricultural engineering technical field, including water receiving pipe, the rear side of water receiving pipe is provided with water seepage pipe assembly, the water seepage pipe assembly includes the four-way joint of installation in water receiving pipe rear side, the right side of four-way joint is connected with water seepage pipe, the bottom of water seepage pipe is all equipped with solenoid valve, the upside of four-way joint is provided with sprinkling irrigation component;By setting water seepage pipe assembly utilizes water seepage hole on the surface of water seepage pipe, it is penetrated into surrounding soil, by solenoid valve opening water flow to the switch of embedded pipe, along with water leakage pole flow direction soil, to quickly give pineapple root water supply;By setting sprinkling irrigation component, according to the different height of pineapple growth, sprinkling irrigation pipe and extension pipe are freely combined by water pipe joint, the height control of sprinkling irrigation is realized;By adjusting handle welded on adjusting head and fixed in water retaining block, the height of water retaining block is changed, so as to extend or shorten water flow distribution area according to actual demand.

The invention relates to the technical field of rare earth extraction sealing equipment, in particular to automatic water injection water sealing equipment of a rare earth extraction production line, which comprises a water injection mechanism, a water sealing mechanism, a flow guide channel and a drainage channel, the water injection mechanism is connected with the lower part of the water tank; the water seal mechanism is connected with the stirring shaft; the flow guide channel is formed in the water injection mechanism; the drainage channel is connected between the water injection mechanism and the water tank; the conical spiral pipe capable of rotating along with the stirring shaft at the same speed rotates in the water seal inner tank, water at the bottom of the outer ring of the water seal inner tank is pumped to the upper portion of the inner ring, the water injection mechanism capable of adjusting the water injection speed along with the water surface height of the inner ring is arranged, and the water surface height of the inner ring is stabilized; the problems that due to high-speed rotation of the stirring shaft, the outer ring is high, the inner ring is low and negative pressure is formed at the position of the inner ring in sealing water in the water seal tank under the action of centrifugal force, and the sealing performance of the water seal becomes poor are solved.
