The invention relates to a purifying device and method for polluted lubricating oil (i.e., dirty oil). The device comprises a magnetic rotator, a centrifuge and a fine filter which are connected sequentially, wherein a liquid outlet of the magnetic rotator is connected with a liquid inlet of the centrifuge through a first adapting pipe, and a liquid outlet of the centrifuge is connected with a liquid inlet of the fine filter through a pipeline. According to the device and the method disclosed by the invention, methods such as rotating-magnetic coagulation, centrifugal separation and membrane type refined filtration are organically combined, so that deep purification of the polluted lubricating oil is achieved; and the restraint, i.e., singleness of the existing equipment is overcome, various impurities such as enginery, water, air and oxidative colloids generated during the use of various kinds of lubricating oil can be effectively removed, the liquid quality of the lubricating oil is remarkably improved, running equipment is reliably guaranteed, the service life of liquid oil is substantially prolonged, the consumption of the lubricating oil is lowered, the cost of the lubricating oil is reduced, the environmental pollution caused by waste liquid oil is reduced, and great direct or indirect economic benefit is produced.

The invention discloses an ecological organic composite fertilizer and its preparation method. The fertilizer is composed of 85-93% of ammonium humate, 5-10% of powdered straw sugar and 2-5% of triple superphosphate. The ammonium humate is composed of the following raw materials: by weight, 50-70% of brown coal powder, 5-10% of urea, 10-20% of ammonium bicarbonate, 5-20% of clear water, and a fully-mixed mixture. The ecological organic composite fertilizer can be adopted to improve physical and chemical properties of soil and viability of ecological vegetation crops. The preparation method is simple, is convenient for popularization, requires low production cost, and has good economic benefits.

The invention provides a buckwheat plant essential oil extraction process. Operation is completed through cooperation of a tripod, a distillation flask, a penetrating hole, a leading-out pipe, a three-way frame set, a chopping device, a fixing frame, a storage frame and a valve connecting pipe. According to the invention, problems that when chopped buckwheat leaves are put into the distillation flask, due to the facts that the pipe opening of the distillation flask is small, the chopped buckwheat leaves are fine, and part of the buckwheat leaves are likely to scatter when the buckwheat leavesare placed, people can cut the buckwheat leaves into large pieces according to the situation so that the buckwheat leaves can be conveniently placed into the distillation flask, but the distillation effect is often delayed due to the large buckwheat leaves, and the like are solved.

The invention relates to a special fertilizer for the desert and desertification control and the preparation method. The special fertilizer comprises the following materials in weight percentage: humic acidic ammonium of 80 percent to 95 percent; monoammonium phosphate, diammonium phosphate or double superphosphate of 3 percent to 10 percent, potassium sulfate or potassium chlorate of 2 percent to 10 percent; or the special fertilizer comprises the following materials in weight percentage: humic acid ammonium of 80 percent to 97 percent and monopotassium phosphate of 3 percent to 20 percent. The preparation method of the special fertilizer comprises: the humic acid ammonium is prepared; the humic acid ammonium of 80 percent to 95 percent, the monoammonium phosphate, diammonium phosphate or double superphosphate of 3 percent to 10 percent and the potassium sulfate or potassium chlorate of 2 percent to 10 percent are mixed fully and uniformly; or the humic acid ammonium of 80 percent to97 percent and the monopotassium phosphate of 3 percent to 20 percent are mixed fully and uniformly; the admixture is grinded into 70 to 90 mesh. The invention has the advantages that the special fertilizer of the invention can improve the soil physicochemical properties and has a coacervation on sand, simultaneously the special fertilizer can stimulate the growth of the root of the green crop for sand control and strengthen the sand stabilization and drought-resistant capacity.

The invention discloses a river channel eutrophication sewage recycling treatment device, which comprises a sedimentation chamber, a sewage discharger, a connecting pipe, a transformation chamber and a drive control system. The slope at the bottom, when in use, pressing the operating lever can drive the cone to move upwards. After the operating lever is released, the cone will fall into the channel and be limited by the channel positioning protrusion. The connecting pipe will lead the water from the sedimentation chamber body into the transformation chamber. The stirring shaft is inserted inside the tank, and the stirring shaft is provided with swirling blades. The air-diffusing circle is a circular metal member with a hollow inside and air-diffusing holes on the side wall. Sludge containing aerobic bacteria is put into the inner cavity at the bottom of the tank body and algae crops are planted on the sludge. The invention can effectively eliminate the nutrient-rich substances in the sewage by setting the conversion chamber, and has reasonable structure and convenient use. The invention is suitable for wide application in sewage treatment.

The invention discloses a high-precision plate washer, relates to the technical field of the plate washer, and specifically includes a support mechanism, a connecting device and a plate washer needle assembly. The front and rear sides of the support mechanism are equipped with connecting devices. The plate washing needle assembly vertically runs through the inside of the support mechanism, and the plate washing needle assembly includes a first gas injection cylinder, a second gas injection cylinder, a third gas injection cylinder, a communication pipe, a liquid injection pipe, an air connection pipe, a rubber folding cylinder, a cone cover, bristles and needle tube, the first gas injection cylinder, the second gas injection cylinder and the third gas injection cylinder are connected in sequence along the vertical direction, the top of the first gas injection cylinder is welded with a liquid injection pipe, and the third gas injection cylinder The bottom end of the injection tube is bonded with a rubber folding tube, and the bottom end of the liquid injection tube is connected with a needle tube. The high-precision washing head can independently control the expansion and contraction of each washing needle through the principle of air pressure, and the amount of expansion and contraction of each washing needle depends entirely on the amount of air drawn out or filled in, so the precision is relatively high. high.
