Description

Technical Field

[0001] The utility model belongs to the technical field of water-fertilizer integrated machines, and specifically relates to a backwashing device for a water-fertilizer integrated machine. Background Art

[0002] The integrated water and fertilizer machine is an important equipment in modern agriculture. It integrates the two functions of irrigation and fertilization, and realizes the integrated management of water and fertilizer. The main function of this equipment is to provide the necessary nutrients for crops within a certain period of time to achieve the purpose of increasing production, improving quality, high quality and high efficiency;

[0003] The fertilization system in the integrated water and fertilizer machine will mix the fertilizer with water, and then deliver it to the root system of the plant through nozzles, drip irrigation devices and other paths. The filter in the integrated water and fertilizer machine is more likely to be clogged by large impurities after long-term use, reducing the filtration efficiency. The common filter cleaning method is to backwash the filter with clean water. The common backwashing method requires multiple times and a large amount of water to wash the filter, and the fine impurities on the surface of the filter are difficult to wash clean. The common backwashing method has a low cleaning efficiency for the filter in the integrated water and fertilizer machine and is prone to waste of resources.

[0004] In order to solve the above problems, a backwash device for a water-fertilizer integrated machine is proposed in the present application. Summary of the invention

[0009] The top of the feed port is slidably connected with a dust cover, the top of the dust cover is overlapped with a top plate, the bottom of the top plate is fixedly connected with a limit plate, the limit plate is movably inserted in the inner cavity of the dust cover, the outer surface of the limit plate is movably connected with the outer surface of the feed port, and by arranging the dust cover, the top plate and the limit plate, the top plate can be subjected to force to drive the limit plate to move up and down, and when the bottom of the top plate contacts the top of the dust cover, the fallen limit plate can prevent the dust cover from moving, and when the dust cover is restricted and blocked at the top of the feed port, external impurities cannot pass through the feed port to pollute the mixture in the mixing tank.

[0010] A heating rod is fixedly inserted into the inner cavity of the stirring tank, and the length of the heating rod is smaller than the length of the stirring tank. By setting the heating rod, the mixing temperature of the liquid in the stirring tank can be increased when the heating rod is activated.

At the same time, the filter in the mixing tank can intercept and filter impurities. When the mixing tank is not working, the micro air pump can be started to release compressed air to the filter through the intake pipe and the exhaust pipe in the reverse direction. The compressed air can loosen or blow off the impurities, dirt and blockages attached to the surface of the filter. After the micro air pump finishes working, the solenoid valve in the cleaning pipe is started again to clean the filter again through the backwashing water source. The combined cleaning method can maximize the cleaning efficiency of the filter and avoid blockage as much as possible.

[0015] The backwash device of the water-fertilizer integrated machine can collect the clean wastewater generated by flushing the filter through the wastewater tank, and try to avoid pollution caused by indiscriminate discharge of clean wastewater. At the same time, the operator can also roughly judge the remaining storage situation inside the wastewater tank through the glass window and the scale. The operator can quickly separate the wastewater tank and the base by rotating the bolts outward, which is convenient for quick removal of the wastewater tank for replacement and maintenance.
