■ For prewash Detergent powder

The detergent powder for preliminary washing according to the present invention is a powder type detergent used for making a detergent solution for injecting high pressure into a vehicle in a pre-wash process, which is a pretreatment process in an automatic car wash, When mixed with water to form a detergent solution.

Conventional pre-wash detergent powders generally consist only of compositions that become liquid components when mixed with water. When the conventional detergent powder is mixed with water and the resulting detergent solution is injected at a high pressure to carry out the preliminary car wash, some of the foreign substances stuck to the painting surface of the vehicle remain, and thus, This can cause minor scratches on the paint surface of the vehicle.

To overcome this problem, the pre-wash detergent powder according to the present invention has a composition comprising insoluble inorganic particles.

In this specification, " insoluble " means a property of maintaining a size of more than a micron (mu m) unit even if it is mixed with water. Therefore, the insoluble inorganic particles contained in the detergent powder according to the present invention are particles that retain particle properties when they are mixed with water and have a size of more than micron unit.

Therefore, the detergent solution, which is a mixture formed by mixing detergent powder and water according to the present invention, has a composition in which inorganic particles having particle characteristics are dispersed in a liquid containing water as a main component.

By injecting the detergent solution having such a composition at high pressure during the preliminary washing process, it is possible to effectively remove the foreign substances adhering to the surface of the vehicle. Specifically, the large kinetic energy of the inorganic particles present in the detergent solution sprayed at high pressure is applied to the foreign substances on the surface of the vehicle, so that the foreign substances can be effectively removed.

Therefore, by performing the preliminary wash using the detergent powder according to the present invention, foreign substances stuck to the surface of the vehicle are cleanly removed, thereby preventing minute scratches on the vehicle paint surface in the brush cleaning process.

However, it is preferable that the size of the insoluble inorganic particles contained in the detergent powder according to the present invention does not exceed the range of 1 to 30 mu m. If the size of the insoluble inorganic particles is excessively large, there is a problem that the coating surface of the vehicle is damaged due to excessive kinetic energy.

The detergent powder according to the present invention may comprise insoluble inorganic particles of different sizes.

For example, detergent powders may contain two insoluble inorganic particles of different sizes. For example, the two insoluble inorganic particles may be a first inorganic particle having a size ranging from 5 to 15 mu m and a second inorganic particle having a size ranging from 15 to 20 mu m.

This detergent powder contains insoluble inorganic particles of various sizes, which makes it possible to more effectively remove the adhered foreign matter as compared with the case where only one size of solid particles is contained.

The insoluble inorganic particle according to the present invention may include at least one of diatomaceous earth, silica, alumina, cerium oxide, zinc oxide, and titanium oxide.

The pre-wash detergent powder according to the present invention may further contain, in addition to the insoluble inorganic particles, other components which are dissolved when mixed with water and are not granular. The absence of granularity herein means that certain components have a size smaller than a micron unit, such as a nanometer (nm) unit.

The non-particulate components that can be included in the detergent powder for pre-wash of the present invention will be described in detail as follows.

The detergent powder according to the present invention may further comprise a surfactant. Surfactants act to remove organic matter such as grease from foreign substances on the surface of the vehicle.

As the surfactant, one or more of an anionic surfactant, a nonionic surfactant, a cationic surfactant and an amphoteric surfactant may be applied. For example, detergent powders contain nonionic surfactants, such as polyoxyethylene alkyl ether and 2-ethylhexanol propoxylated ethoxylated polymer, in the same weight ratio can do.

Further, the detergent powder according to the present invention may further comprise an antioxidant. Antioxidants prevent oxidation of the surfactant by decomposition. As the antioxidant, Etidronic acid may be used.

Further, the detergent powder according to the present invention may further contain an inorganic salt. Inorganic salts act as a component on the surface of the vehicle. As inorganic salts, sodium carbonate, sodium bicarbonate, sodium bicarbonate and the like can be used.

The detergent powder according to the present invention may further comprise an organic acid. The organic acid serves to remove inorganic foreign substances on the surface of the vehicle. As the organic acid, citric acid, oxalic acid, nitrilotriacetic acid and the like can be used.

Further, the detergent powder according to the present invention may further comprise an ion sequestering agent. Ion sequestering agents act to remove ions in water. As the ionic blocking agent, ethylenediaminetetraacetic acid (EDTA) may be used.

■ Spare car wash system

Hereinafter, a prewash system for generating and injecting a prewash detergent solution using the detergent powder described above with reference to FIGS. 1 and 2 will be described.

Although the pre-wash system described herein is particularly suitable for detergent powders containing insoluble inorganic particles such as the detergent powders described above, it is equally suitable for other types of detergent powders not containing such insoluble inorganic particles Can be used.

1 and 2, a preliminary car wash system according to an embodiment of the present invention includes a detergent solution supply device 10, a water supply source 20, a boom 30, a swivel 40, and a spray nozzle 50 .

The detergent solution supply device 10 is a device for mixing a detergent powder and water to generate a detergent solution and discharge it to a high-pressure state.

The water supply source 20 supplies the detergent solution supply device 10 with water necessary for generating a detergent solution. By way of example, the water source 20 may be a water supply valve connected to a water line.

The detergent solution discharged from the detergent solution supply device 10 is supplied to the injection nozzle 50 through the nozzle connection line 51. The nozzle connecting line 51 is disposed so as to pass through the inside of the boom frame 30 so as not to be attracted to the floor of the work place and the boom frame 30 supports part of the nozzle connecting line 51, And a swivel 40 is provided.

The spray nozzle 50 serves to spray the high-pressure detergent solution supplied from the detergent solution supply device 10 onto the surface of the vehicle. As shown in FIG. 2, the spray nozzle 50 is typically provided in a gun shape. When a worker pulls a trigger switch (not shown) provided in the spray nozzle 50, the detergent solution is sprayed from the spray nozzle 50, and the trigger solution is stopped when the trigger switch is released.

2, the detergent solution supply device 10 includes a detergent dispenser 62, a detergent solution supply tank 70, a pump 80, and a control panel 90.

The detergent dispenser (60) is disposed on the detergent solution supply tank (70) and supplies detergent powder to the detergent solution supply tank (70). In the detergent dispenser 60, a transfer screw (not shown) that is operated by a motor 61 may be provided. When the motor 61 is operated under the control of the control panel 90, the conveying screw rotates, and the detergent powder is discharged downward from the detergent dispenser 60.

The detergent solution supply tank 70 receives the detergent powder and water from the detergent dispenser 60 and the water supply source 20, respectively, to generate and receive the detergent solution.

The detergent solution supply tank 70 may be provided with a high-level sensor 71 and a low-level sensor 72.

When the amount of the detergent solution in the detergent solution supply tank 70 is detected by the high water level sensor 71 to reach the preset maximum level, the detergent dispenser 60 and the water source 20 ) Is stopped.

On the other hand, when it is detected by the low-level sensor 72 that the amount of the detergent solution in the detergent solution supply tank 70 has reached the predetermined minimum level, the detergent dispenser 60 and the water supply source The operation of the motor 20 is resumed.

In this way, the level of the detergent solution in the detergent solution supply tank 70 can be maintained between the highest water level and the lowest water level.

The pump 80 receives the detergent solution from the detergent solution supply tank 70 and turns the detergent solution into a high pressure state to supply it to the injection nozzle 50. That is, when the operator pulls the trigger switch (not shown) of the spray nozzle 50, the pump 80 is operated via the control panel 90, so that the high-pressure detergent solution is supplied to the spray nozzle 50.

The preliminary car wash system according to the embodiment of the present invention has a structure in which detergent powder and water are mixed in the detergent solution supply tank 70 to generate a detergent solution spontaneously and the detergent solution is discharged at a high pressure by the pump 80 .

Unlike the embodiment of the present invention, the pump 80 directly receives water from the water supply source 20 and discharges the water from the water supply source 20 at a high pressure. While the mixture of water and detergent powder is mixed through the separate supply line, An alternative structure may be considered in which the water is sucked into the water supply line on the upstream side or the downstream side and mixed with the high-pressure water flowing in the water supply line.

However, according to such an alternative structure, there may arise a problem that the mixture of detergent powder does not flow smoothly into the water supply line. Particularly, when connected to the water supply line on the upstream side of the pump 80, insoluble inorganic particles contained in the detergent powder may damage components (such as a blade, a rubber packing or a piston) There is a problem that it is difficult to use powder.

However, since the pre-wash system according to the embodiment of the present invention has a structure in which the pump 80 discharges the pre-generated detergent solution in the detergent solution supply tank 70 at a high pressure, the detergent powder is injected into the water at a proper ratio (E.g., a blade, a rubber packing, or a piston) can be prevented from being damaged by insoluble inorganic particles even when a detergent powder containing insoluble inorganic particles is used.

■ Detergent solution Supply tank

Hereinafter, the detergent solution supply unit 100 will be described in detail with reference to FIGS. 3 to 6. FIG.

As described above, the detergent solution supply tank 70 receives the detergent powder and water from the detergent dispenser 60 and the water supply source 20, respectively. The detergent solution is supplied to the pump 80, .

According to an embodiment of the present invention, the detergent solution supply tank 70 includes a supply tank main body 100, a side guide table 200, and an upper cover 300.

The supply tank main body 100 has a container shape including a main body bottom 110 and a main body side 120. A detergent solution discharge line 12 is connected to the bottom 110 of the main body. A side guide 200 is disposed in an upper space of the supply tank main body 100 and an upper cover 300 is mounted on an upper end of the supply tank main body 100.

The detergent dispenser 60 described above is mounted on the upper cover 300. As shown in FIG. 3, two detergent dispensers 60 may be provided. The number of the detergent dispensers 60 may be changed to one, three, or the like.

The side guide base 200 includes a guide base 210 and a guide base side 220.

The guide base 210 has an inclined rectangular plate shape and the guide base side portion 220 has a front end side portion 222, a rear end side portion 221, a long left side portion 223 located on the left side, And a right side portion 224. Thus, the side guide base 200 generally has a shape similar to a slide.

The side guide base 200 receives the detergent powder from the detergent dispenser 60 disposed on the upper side and receives water from the water supply source 20 through the water supply line 11 connected to the rear end side portion 221.

6, the detergent powder introduced into the side guide band 200 is discharged to the outside of the side guide band 200 because the detergent powder is wasted in the water flowing along the guide band bottom 210.

The mixture of water and detergent powder discharged from the side guide rails 200 does not fall directly toward the bottom 110 of the main body but is discharged from the bottom of the main body 100, And contacts the side portion 120 first.

4, the front end side portion 222 is located at the front end of the side guide 200 and the front end side portion 222 is positioned so that the detergent powder exiting through the lateral guide 200 is not in a loose state. A plurality of elongated slit-shaped discharge holes 222a are formed.

Alternatively, as shown in FIG. 5, the second side portion 222 may be formed with a plurality of discharge holes 222a arranged in a lattice form. 5, each discharge hole 222a is shown in a circular shape, but its shape can be variously changed into a square shape, a hexagonal shape, or the like.

3 and 6, the mixed liquid (detergent solution) of water and detergent powder discharged from the side guide base 200 toward the body side surface 120 is discharged through the inclined side surface portion 121 provided in the body side surface portion 120 And flows toward the main body bottom 110. [

In other words, the water supplied to the detergent solution supply tank 70 and the detergent powder are simultaneously discharged to the side wall of the supply tank main body 100 by the side guide bracket 200, then flow on the inclined side surface portion 121, And is housed in the bath 70.

If the water and the detergent powder poured into the detergent solution supply tank 70 are directly poured into the bottom of the supply tank 70, the water and the detergent powder may be mixed with each other to cause bubbles. In the present invention, It is possible to prevent the occurrence of such bubbles because it is discharged to the side wall of the detergent solution supply tank 70 by the base 200 and then flows on the inclined side surface portion 121. [

3 and 6, the main body side surface portion 120 includes the second side surface portion 122, the third side surface portion 122, the third side surface portion 123, A fourth side surface portion 124, a fifth side surface portion 125, and a sixth side surface portion 126, as shown in FIG.

Here, the second side surface portion 122 is a rectangular vertical plate as a portion arranged opposite to the front end of the side guide base 200. The mixed liquid (detergent solution) discharged from the side guide band 200 first contacts the second side portion 122 and then flows toward the bottom portion 110 of the main body on the first side portion (inclined side portion) 121 described above.

The third side portion 123 is a rectangular plate that is arranged obliquely as the first side portion 121. However, the inclination angle of the third side portion 123 is steeper than the inclination angle of the first side portion 121.

The fourth side surface portion 124 is a rectangular vertical plate that extends to the upper side of the third side surface portion 123.

The fifth side surface portion 125 and the sixth side surface portion 126 are trapezoidal vertical plates having the same height as the height of the supply tank main body 100.

With the above-described structure, the upper part of the supply tank main body 100 has a rectangular parallelepiped shape, while the lower part of the supply tank main body 100 has a history truncated pyramid shape. Accordingly, the lower part of the supply tank main body 100 becomes gradually narrower as it goes downward, and the bottom part 110 of the main body located at the bottom has a considerably narrow area.

When the main body bottom 110 has a large area, some components of the detergent solution may settle and accumulate in a region far from the center of the main body bottom 110. In the embodiment of the present invention, Since the bottom of the main body 110 has a shape, the problem of depositing and accumulating detergent solution in the main tub 100 can be prevented.
