Summary of the invention
The utility model purpose is, a kind of automatic leaching device of soil column simulation test is provided, this device is made up of water storing tank, drinking-water pipe, lack of water sensor, Wriggling Pump Head, peristaltic pump controller, LCD demonstration and button, water injection pipe, universal rapid-acting coupling, vent valve, transparent upper cover, sprinkle seat cavity, transparency protected shell, syringe needle, O-ring seal, this device can accurately be simulated rainfall grade in various degree, realizes stage by stage, branch intensity carries out automatic sprinkle to earth pillar; Control accuracy height, flow scalable in the 0-1000ML/M scope, the rainfall amount of accumulative total can show in real time.Leaching raindrop good uniformity, volume is small and exquisite, and controllability is good, and is easy to adjust accurate, can carry out the simulation of rainfall leaching at regular time and quantity automatically by flow velocity, flow, rainfall intensity, is applicable to that the rainfall sprinkle of laboratory column simulation test adds water.This analogue means control accuracy height, practicality simple to operate, can according to the big freedom in minor affairs of earth pillar surface area determine the quantity of syringe needle reach drip spill fully evenly, and it is little to be detained solution amount in pipeline and the shower.
The automatic leaching device of a kind of soil column simulation test described in the utility model; this device is by water storing tank; drinking-water pipe; the lack of water sensor; Wriggling Pump Head; the peristaltic pump controller; LCD shows and button; water injection pipe; universal rapid-acting coupling; vent valve; transparent upper cover; sprinkle seat cavity; transparency protected shell; syringe needle; O-ring seal is formed; water storing tank (1) is connected with Wriggling Pump Head (4) by drinking-water pipe (2); Wriggling Pump Head (4) is connected with the universal rapid-acting coupling (8) at sprinkle seat cavity (11) top by water injection pipe (7); at several syringe needles arranged in a uniform (13) of sprinkle seat cavity (11) internal fixation; outside surface at sprinkle seat cavity (11) is provided with transparency protected shell (12); adopt fixedly transparent upper cover (10) of screw (15) at the top of shell (12), and between shell (12) and transparent upper cover (10), be provided with O-ring seal (14).
Drinking-water pipe (2) is gone up lack of water sensor (3) is installed, and peristaltic pump controller (5) one ends connect Wriggling Pump Head (4), and the other end connects LCD display (6).
Sprinkle seat cavity (11) top one side is provided with vent valve (9).
The automatic leaching device of a kind of soil column simulation test described in the utility model, the peristaltic pump controller can be provided with flow velocity in this device, preset flow and divide the intensity sprinkle stage by stage, the while can connect computing machine, tests the associating use with the earth pillar sprinkle.Trickle automatic stop arrangement corrosion resistivity is strong, can carry out multiple solution and carry out sprinkle.As required, spraying device can be made into circle or square structure; Can be according to the upper end area of earth pillar, the quantity of increase and decrease syringe needle also can be by changing the control that the syringe needle size further enlarges rainfall intensity.The upper strata of sprinkle seat cavity is transparent PC plate, and the intensity ageing, and anti is good.Transparent loam cake can be observed the full level of solution.Top of the upper layer is equipped with universal rapid-acting coupling and exhausr port, and universal rapid-acting coupling is connected with the lack of water sensor by water injection pipe, after first use or air inlet, carries out exhaust by exhausr port, evenly drips to reach each syringe.Because after the shower exhaust, inner fluid pressure is uniformly, so the liquid that oozes by each syringe needle also is uniform.Can realize the automatic control of simulated rainfall intensity by the flow velocity size, press flow size control realization simulated rainfall amount automatically, improve the accuracy of efficient and test greatly, thoroughly break away from the inconvenience that manually-operated brings.
