The invention belongs to the technical field of screen sintering, and particularly discloses a screen sintering furnace and a method for screen sintering by using such furnace. According to the technical scheme provided by the invention, the screen sintering furnace comprises a furnace body consisting of a furnace wall and a furnace chamber, wherein a hydraulic mechanism is arranged above the furnace body; a first through hole is formed on the furnace wall; a second through hole is formed at a position corresponding to the first through hole above the sintering chamber; a hydraulic ejector rod of the hydraulic mechanism penetrates through the first through hole and the second through hole; and the hydraulic ejector rod comprises a heat-resistant ejector rod at the top end and a metal supporting rod behind the heat-resistant ejector rod. At the time of sintering, the pressure between meshes in a sintering net is increased, so that one-time sintering formation is realized; compared withsintering, cold rolling, resintering or multiple circulation adopted in the conventional process, the energy consumption is reduced, the production cost is reduced, an isolating layer is saved, a cleaning process is saved, and the working efficiency is increased; and the problem of damage caused to a stainless steel material is reduced, so that the filtering accuracy of a sintering screen is moreuniform.

The invention discloses a cleaning unit, a welding module and welding equipment. According to one embodiment of the present invention, there can be provided a cleaning unit comprising: a gas injection unit that is disposed above an object to be cleaned and that injects gas obliquely toward the object in order to separate contaminants on the object from the object; and a suction unit which is provided on one side of the air blowing unit and includes a suction port for sucking and removing the contaminant separated from the object by the air blowing unit.

The invention provides a supercritical carbon dioxide dyeing system. The supercritical carbon dioxide dyeing system comprises a dyestuff mechanism, wherein the dyestuff mechanism comprises an extracting device and a dyeing device; the extracting device comprises a plant dyestuff extracting kettle; the dyeing device comprises a natural plant dyestuff kettle and a dyeing kettle; the plant dyestuff extracting kettle and the natural plant dyestuff kettle are connected in parallel in the carbon dioxide dyeing system; and after the plant dyestuff extracting kettle is in parallel connection with the natural plant dyestuff kettle, a discharging end passes through a feeding end of the dyeing kettle. The invention further provides a supercritical carbon dioxide dyeing process which comprises a cleaning process. According to the supercritical carbon dioxide dyeing system and method, equipment of the system and the process are optimally combined; the production efficiency of the supercritical carbon dioxide dyeing technology is greatly improved, meanwhile, automated extracting mode is realized, the work intensity is relieved, and safety accidents are avoided.

The invention discloses a method for producing whitened flour. The method comprises the following steps of: inspecting wheat; cleaning crude wheat; adjusting the moisture of the wheat; cleaning hulled wheat; grinding; bolting; feeding into a purifier; performing magnetic separation, and packaging; and warehousing. By the method, a cleaning process is added, so that a cleaning effect is well enhanced; white wheat and red wheat are reasonably mixed, so that flour with the whiteness of 80 can be produced without the addition of any additive; and simultaneously, the original flavor of the flour is ensured at the same time.

The invention discloses a road cleaning vehicle, which comprises a chassis (1), a power system (3), a suction nozzle device (7) and a dustbin (8). The road cleaning vehicle also includes a rolling brush device (4), a rolling brush device (4) It is installed under the chassis (1) and includes a roller brush arranged in front of the suction nozzle device (7). Based on the road cleaning vehicle provided by the present invention, the rolling brush device can clean the road surface in the middle of the road cleaning vehicle, so when the road surface is particularly dirty, using the rolling brush device to clean can add a cleaning process, thereby improving the cleaning efficiency of the road cleaning vehicle .

The invention discloses a clean tea production process. The production process comprises the following steps: rotationally rinsing, spray washing, rotationally whirling, drying with cold air, spreading out, grading, deenzyming, primarily winnowing, spreading for drying in the air, primarily rolling, frying at constant temperature in the way of electric heating, spreading out, rolling, winnowing, blending, piling, completely baking, preparing into finish products, inspecting and warehousing. The cleaning process and primarily winnowing processes are added, and the external impurities can be removed; electric-heating constant-temperature frying is adopted to replace the traditional primarily baking process, thus the tea can be heated uniformly and can be prevented from being polluted by other heating materials; dried-up tea dust or carbonized tea dust can not be generated; the tea is held with containers when transferred among different processes; dust and residues are removed in each process in production so that the tea can not be polluted and can not generate pollution impurities in the processing process; thus the purpose of clean tea production is achieved; and the tea does notneed to be washed when brewed, thus greatly improving the utilization of the nutritive substances of the tea.

The invention provides a method for plating a nickel coating on the electrosparking surface of an electronic packaging aluminum-base composite material, relating to a method for chemically plating a nickel coating on the electrosparking surface of an aluminum-base composite material. The invention aims to solve the problems that the processing procedure and cost are increased and the binding force between the coating and matrix is weak since the electrosparking surface of the existing electronic packaging aluminum-base composite material needs to be ground and milled after electrosparking. The method comprises the following steps: 1. cleaning; 2. acid etching; 3. oil removal; 4. primary zinc soaking; 5. nitric acid removal; 6. secondary zinc soaking; and 7. plating. The method directly plates the Ni-P coating on the electrosparking surface of the electronic packaging aluminum-base composite material, and has the advantages of low cost, simple coating procedure and stable coating technique; and the thickness of the Ni-P coating is 5-10 mu m. The nickel-plated electronic packaging aluminum-base composite material is applicable to the field of electronic packaging materials.
