Description

Special cleaning tool for removing tree oil from vehicle covering part

Technical Field

The utility model relates to a special cleaning tool for removing tree oil from a vehicle covering part, in particular to the technical field of special cleaning tools for removing tree oil from the surface of the vehicle covering part.

Background

Many trees secrete oil, a viscous organic gum, during the active growth period of high air temperature. When the secretion is excessive and the storage space of the tree is insufficient, the surplus is discharged out of the tree. In addition, the branches and trunks of trees secreting tree oil are eaten by insects, trimmed or otherwise injured, and the tree oil is also discharged from the body of the trees at the wound. In the above case, once we park the vehicle near or under the tree, tree oil droplets often drip or are blown off by the wind and adhere to the vehicle cover, seriously affecting the vehicle aesthetics; due to the organic solvent component contained in the resin, the resin can corrode and dissolve the painted surface without being cleaned for a long time, and the covering part is permanently damaged (the aesthetic property and the corrosion prevention capability). Because the tree oil has strong viscosity and strong affinity with the paint surface of the automobile covering part, the tree oil is very difficult to remove by a conventional cleaning method and generally needs to be treated by a special car washing mechanism. Generally, two methods, i.e., a mechanical polishing method and a chemical (mainly, chemical solvent) cleaning method, are not limited to the above methods, and have the following problems: firstly, a mechanical polishing method is adopted, firstly, the thickness of the painted surface of a covering part is inevitably reduced, so that the corrosion resistance is reduced, and secondly, if the whole vehicle is not polished, the brightness of the covering part of the whole vehicle is inevitably inconsistent, so that the attractiveness of the vehicle is influenced; the chemical method comprises the following steps of firstly, carrying out cleaning work for a long time, making materials expensive, and having high cost, secondly, having strong corrosivity and damaging the brightness of the paint surface, directly influencing the attractiveness of a vehicle, seriously causing the corrosion of the paint surface, seriously reducing the corrosion resistance, and causing harm to people due to improper operation, thirdly, using and storing the chemical which is used as the cleaning agent and mostly is a combustible organic solvent, so that fire hazard exists, and fourthly, discharging a large amount of chemical into the environment to cause serious pollution.

After long-time careful observation and special evidence finding of a plurality of special car washing mechanisms, the inventor discovers that: after entering a season with lower air temperature in northern China, tree oil attached to a vehicle covering part can be easily and completely removed after regular cleaning, and a large amount of time and money are not spent for special cleaning at all.

Disclosure of Invention

Aiming at the problems, the utility model provides a special cleaning tool for removing tree oil from a vehicle covering part based on observation and analysis of reality. The method utilizes the characteristic that different materials have different thermal expansion rates, and the tree oil on the vehicle covering part is removed by cooling the vehicle covering part attached with the tree oil, destroying the close bonding of the vehicle covering part and the low-temperature tree oil and timely mechanically stripping the low-temperature tree oil. Specifically, the utility model designs a special tool for cleaning tree oil by utilizing the principles of vortex tube refrigeration and Bernoulli principle of vane pump motor, which uses compressed air as the power source of the vortex tube and the motor, and clean water as the cleaning medium and auxiliary refrigerant, and sprays a small amount of clean water when cooling the vehicle covering part attached with the tree oil, and the flexible silica gel scraper on the scraping disc driven by the motor peels off and cleans the tree oil which is cooled to be hard and brittle, and the special tool is moved at a proper speed to remove the tree oil gradually and easily, thereby restoring the appearance of the vehicle.

The specific method comprises the following steps: the utility model relates to a pure physical cleaning method, wherein a vortex tube on a special tree oil cleaning tool divides compressed air from an air compressor into a cold path and a hot path (a vortex tube refrigeration principle), the cold air at a cold nozzle locally cools a vehicle covering part attached with tree oil (in particular, when high-speed cold air sprayed from the cold nozzle is used, a small amount of clean water is sucked by using a Bernoulli principle to form cold water mist to cool the local range of the covering part and the tree oil on the covering part, water drops in the cold water mist are adsorbed by the covering part to form a cold water film), and the tree oil is rapidly cooled by the cold water mist due to the thin wall of the covering part and the small volume (small heat capacity) of the tree oil, so that the tree oil is rapidly changed from sticky to hard and crisp. Because of the difference of the heat conductivity coefficient, the heat capacity and the thermal expansion coefficient, the thermal expansion and the cold contraction of the two are different in steps in the temperature change process, the tight combination of the two is easy to break, and the tree oil is directly separated from the paint surface or is easily stripped by a scraping blade driven by a motor and is taken away from the covering piece by water flow. The special tool is moved at a proper speed (the low-temperature hard and crisp tree oil is ensured), so that the tree oil on the vehicle covering part is cleaned (the hot air sprayed by the vortex tube hot nozzle is directly exhausted into the atmosphere).

Compared with the conventional chemical cleaning method for the tree oil, the chemical cleaning method for the tree oil adopts a pure physical method, uses compressed air and purified water as a refrigerant and a cleaning medium, and uses the air motor with a simple structure as the power of the cleaning machine, so that the chemical cleaning method for the tree oil has the remarkable advantages of small equipment investment, low material consumption, quick operation, no pollution, no corrosion, no fire hazard, no electric shock hazard, safety and reliability (the motor is used as main cleaning power, no potential safety hazard), low operation cost and the like. If the cold and hot nozzles of the vortex tube are exchanged, the hot cleaning of the vehicle covering part can be realized, and the cleaning service area is enlarged. Therefore, the utility model has higher social value and economic value and higher market promotion value.

Third, the working process

As shown in fig. 3:

firstly, connecting a central air passage of a handle 4 of a special cleaning tool for a compressed air outlet of an air compressor by using an air conveying pipe (not shown), then adjusting the opening degrees of a motor control valve 8, a vortex tube control valve 3 and an air valve 23 to obtain the proper rotating speed of a motor 5, the proper cold air temperature of a cold nozzle of a vortex tube 25 and the proper water yield of a water spraying tube 24, then, holding the handle 4 by hand to enable the special cleaning tool to be close to the area of a covering part attached with tree oil, and enabling a scraping blade 18 to be attached to the covering part with proper force.

Secondly, compressed air from the compressor enters the branch air channel through an air inlet channel in the center of the handle 4 and is divided into two paths simultaneously.

Enters the air branch passage of the motor 5 and enters the air inlet hole of the motor 5 through the motor control valve 8 (controlling the rotating speed of the motor 5), the motor 5 is driven to drive the scraping disc 19 to rotate, and the formed low-pressure air is discharged into the atmosphere through the air outlet hole of the motor 5.

Enters a branch air passage of the vortex tube 25, passes through the vortex tube control valve 3 (controls the spraying amount and the temperature of cold air of the vortex tube 25), then enters the interior of the vortex tube 25 and is divided into two paths. One path of cold air is sprayed out through the cold nozzle of the vortex tube 25, because the pressure intensity of the high-speed air flow is reduced, namely a small amount of purified water is sucked from the spray tube 24 (Bernoulli principle) and is smashed by the cold air flow to form cold water mist, and because the purified water is sucked out and a certain negative pressure is formed in the water storage tank 20, the air enters the water storage tank 20 through the air valve 23 (automatically controlling the air inlet flow) to perform volume compensation and maintain a certain vacuum degree, so that the water flow of the spray tube 24 is adjusted. When the special cleaning tool is not in operation, the water storage tank 20 has a certain vacuum degree to prevent the purified water from leaking from the nozzle of the spray pipe 24.

The cold water mist (cold air and water drops cooled by the cold air with lower temperature) passes through a channel formed by central holes of the hollow shaft 10, the end cover 15 and the fixed disc 17 and passes through gaps among the scraping sheets 18 to wash and cool the covering piece and the tree oil attached to the covering piece (part of the water drops in the cold water mist are adsorbed on the covering piece to form a water film), the covering piece and the tree oil attached to the covering piece are rapidly cooled, and the tree oil is rapidly changed from sticky to hard and brittle. In the process of temperature change, the covering part and the tree oil in the cooled area have different heat conductivity coefficients, heat capacities and thermal expansion coefficients, so that the expansion with heat and the contraction with cold are different, the tight combination of the covering part and the tree oil is rapidly damaged, and the hard and brittle tree oil is directly separated from the covering part or is separated from the covering part by the water flow after being stripped by the scraping blade 18 on the fixed disc 17 driven by the rotor 12 to rotate (the hydrophilic wetting effect of the water can reduce the excessive damage of the scraping blade 18 to the paint surface of the covering part and prevent the fallen tree oil from being attached to the covering part again).
