[0001] The present invention relates to a cleaning method for removing dirt adhering to objects to be cleaned such as machine parts, electronic parts, and medical devices.

Background Art

[0002] When manufacturing industrial products such as metals, ceramics, and resins, heat is generated during processing such as pressing and cutting. Therefore, it is common to perform operations while cooling the material with processing oil. Therefore, when such processing is performed, dirt such as oil and cutting chips adheres to the industrial products that are the objects to be cleaned in the present application, and it is necessary to remove them.

[0004] When cleaning such objects to be cleaned, it has been common in the past to use a large amount of cleaning solvent as shown in Patent Document 1. However, the use of such a large amount of cleaning solvent has caused photochemical smog, ozone layer depletion, soil pollution, and pollution. In addition, in 1995, Freon 113, 1,1,1-trichloroethane was completely phased out worldwide, and in recent years, reducing carbon dioxide emissions has become a global issue. Therefore, in order to solve such problems, it is necessary to significantly reduce the amount of cleaning solvent used during cleaning.

Problems to be Solved by the Invention

[0005] However, in cleaning processes commonly performed today, such as grease removal, carbon removal, water-soluble cutting fluid removal, and even scale removal and deburring, strong physical force is sometimes required. Even with the use of large amounts of solvent, it has been difficult to achieve sufficient effectiveness in cleaning processes requiring such strong physical force.

[0006] Therefore, this invention aims to solve the aforementioned problems and to provide a cleaning method that can easily and reliably achieve a cleaning effect without using large amounts of cleaning solvent, especially when strong physical force cleaning is required. [Means for solving the problem]

[0007] To solve the above-mentioned problems , this application The method involves a first cleaning process in which a water-soaked object to be cleaned is brought into contact with heated oil heated to over 100°C. The pressure of the steam generated when the water on the object comes into contact with the heated oil physically removes the dirt attached to the object and heats the object to over 100°C. A second cleaning process is then performed after the first cleaning by immersing the object in heated water mixed with an abrasive. The pressure of the steam generated when the object comes into contact with the heated water and the contact of the abrasive with the object physically remove any dirt remaining on the object after the first cleaning. By performing the first cleaning with heated oil and the second cleaning with heated water and an abrasive in succession, the cleaning effect of the object to be cleaned can be further enhanced.

[0008] Furthermore, the heating oil may contain an abrasive. By mixing an abrasive into the heating oil in this way, for example, by bringing an object to be cleaned, which has water attached to it, into contact with heating oil heated to 100°C or higher, the pressure of the water vapor generated when the water attached to the object comes into contact with the heating oil can physically remove the dirt attached to the object. At this time, the contact of the object to be cleaned with the abrasive mixed into the heating oil becomes more pronounced, which further improves the physical removal effect of the dirt attached to the object to be cleaned. [Effects of the Invention]

[0009] The present invention As described above, this method requires that the object to be cleaned, heated to over 100°C, be immersed in heated water mixed with abrasive material. The pressure of the steam generated when the object comes into contact with the heated water, and the contact of the abrasive material with the object, physically remove the dirt attached to the object. In this way, two different physical removal methods—steam pressure and contact with the abrasive material—make it possible to quickly and effectively remove stubborn oil stains, burrs, scale, and other dirt attached to the object that require strong physical cleaning and are difficult to remove with chemical cleaning.

[0010] Also, book Vow The method involves a first cleaning, in which the pressure of steam generated when water adhering to the object to be cleaned comes into contact with the heated oil physically removes the dirt adhering to the object, and a second cleaning, in which the pressure of steam generated when the object to be cleaned comes into contact with the heated water and the contact of the abrasive material with the object to be cleaned physically removes the dirt remaining on the object after the first cleaning, in a continuous process. In this way, the object to be cleaned is heated to a temperature higher than 100°C with the heated oil, and the first cleaning is performed to remove the dirt before cleaning with the heated water and abrasive material. By performing physical removal cleaning by steam pressure and contact with the abrasive material twice in a row, it is possible to further enhance the cleaning effect of the heated water and abrasive material.

[0011] In recent years, restaurants that grill food on a net, such as yakiniku and barbecue, have become popular in the food and beverage industry. In these types of restaurants, it has traditionally been common practice to hand-wash used nets and jigs that have meat grease and other residues attached to them by scrubbing them with a brush, which has resulted in a complicated and costly cleaning process. Vow By cleaning the mesh and jigs using the method described above, oil, dirt, and other contaminants adhering to the used mesh and jigs can be easily and reliably peeled off and removed. VowSince it does not require cleaning solvents, it can be safely used for cleaning tools used when handling food, such as grills and jigs for barbecuing, as described above, making it ideal. [Brief explanation of the drawing]

[0012] [Figure 1] A conceptual diagram of Embodiment 1 illustrating the present invention. [Example 1]

[0013] Book Actual results of the proposed invention Execution Example 1 is shown in Figure 1. Let us explain this further. (41) is a heated water tank, which is equipped with a first heater (42) and a first temperature sensor (43) inside. Also inside the heated water tank (41), Figure 1 shows As shown, a stirring blade is provided at the tip of the shaft, and a stirrer (44) is provided to stir the liquid in the heated water tank (41).

[0014] The heated water tank (41) contains heated water (45) heated by the first heater (42), and is heated to a predetermined temperature of 100°C or less by the first temperature sensor (43). Abrasive material (46) is mixed into the heated water (45). This abrasive material (46) can be fine particles or small pieces of wood, rubber, glass, plastic, metal, etc., and can be appropriately selected depending on the purpose. By operating the stirrer (44), the abrasive material (46) can be uniformly dispersed in the heated water (45).

[0015] Also Figure 1 shows As shown, a heating oil tank (47) is provided adjacent to the heating water tank (41). Inside this heating oil tank (47) is a heating oil (48) with a boiling point exceeding 100°C. A second heater (51) and a second temperature sensor (51) are also located in the heating oil tank (47), and the heating oil (48) is constantly maintained at a temperature of 100°C or higher and below the boiling point of the heating oil (48) by the second heater (51) and the second temperature sensor (51).

[0016] Also, inside the heating oil tank (47), Figure 1 shows as shown, a stirring blade is provided at the tip of the shaft, and a stirrer (50) is provided that can stir the heating oil (48) inside the heating oil tank (47). Abrasive material (49) is mixed into the heating oil (48). Note that this abrasive material (49) is fine-grained or small-piece-shaped wood, rubber, glass, plastic, metal, etc., and can be appropriately selected according to the cleaning purpose. By operating the stirrer (50), it becomes possible to uniformly disperse the abrasive material (49) in the heating oil (48).

[0017] Also, a separation device (53) is connected to the above heating water tank (41). Figure 1 shows As shown, that is, one end of the first pipe (56) is connected to the opening (59) side of the above heating water tank (41), and the other end of the first pipe (56) is connected to the separation device (53). This separation device (53) can separate the moisture (54) and oil component (55) in the liquid transferred from the above heating water tank (41). And the moisture (54) separated by the separation device (53) can be refluxed into the heating water tank (41) again through the second pipe (57), and the oil component (55) separated by the separation device (53) can be refluxed into the above heating oil tank (47) through the third pipe (58).

[0018] A cleaning method for the object to be cleaned (60) using the cleaning device (40) configured as above will be described below. First, regarding the first cleaning of this embodiment, when explaining, the object to be cleaned (60) is immersed in water in a water tank (not shown), or water is attached to the object to be cleaned (60) by a method such as spraying shower water, and in this state, it is immersed in the heating oil (48) inside the above heating oil tank (47). By immersing the object to be cleaned (60) with water attached in the heating oil (48) at 100°C or higher, the water attached to the object to be cleaned (60) instantaneously evaporates when it comes into contact with the heating oil (48).

[0019] Therefore, due to the pressure of the water vapor generated during the instantaneous evaporation of this water, the dirt adhering to the object to be cleaned (60) is physically peeled off. Also, at this time, since the abrasive (49) is mixed in the heating oil (48), the water adhering to the object to be cleaned (60) instantaneously evaporates as described above, and along with the instantaneous evaporation of the water, the heating oil (48) becomes fluid, and the contact of the abrasive (46) with the object to be cleaned (60) becomes intense.

[0020] In addition, in this embodiment, as described above, the abrasive (46) is mixed in the heating oil (48), but in other different embodiments, it is not limited to this, and only physical peeling by the pressure of water vapor may be performed in the heating oil tank (47) without mixing the abrasive (46) in the heating oil (48).

[0021] Therefore, it is also possible to physically peel off and remove the dirt adhering to the object to be cleaned (60) by the intense contact of the abrasive (46) with the object to be cleaned (60). Therefore, in this cleaning method, the physical force due to the pressure caused by the instantaneous evaporation of the heated water (45) and the physical force due to the intense contact of the abrasive (49) with the object to be cleaned (60) generated simultaneously can remove the dirt, burrs, scale, etc. adhering to the object to be cleaned (60) with a strong force. Also, by immersing the object to be cleaned (60) as described above, it is possible to heat the temperature of the object to be cleaned (60) to 100°C or higher.

[0022] And after the first cleaning is completed, the second cleaning is performed. Regarding the second cleaning, first, the first cleaning is performed as described above, and the object to be cleaned (60) heated to 100°C or higher is taken out from the heating oil tank (47) and immersed in the heated water (45) in the heating water tank (41). By immersing the object to be cleaned (60) heated to 100°C or higher in the heated water (45) in this way, the heated water (45) contacting the object to be cleaned (60) instantaneously evaporates. Therefore, due to the pressure of the water vapor generated during the instantaneous evaporation of this heated water (45), the dirt adhering to the object to be cleaned (60) can be physically peeled off.

[0023] Furthermore, since the heated water (45) contains an abrasive (46), the instantaneous evaporation of the water causes the heated water (45) to become fluid, and the abrasive (46) comes into more intense contact with the object to be cleaned (60). Therefore, even through the intense contact of the abrasive (46) with the object to be cleaned (60), it becomes possible to physically peel off and remove the dirt attached to the object to be cleaned (60). Consequently, in this second cleaning, the physical force caused by the pressure from the instantaneous evaporation of the heated water (45) and the physical force caused by the intense contact of the abrasive (46) with the object to be cleaned (60) that occurs simultaneously, make it possible to powerfully remove dirt, burrs, scale, etc. attached to the object to be cleaned (60) that could not be removed in the first cleaning.

[0024] Thus, since the first cleaning process involves two separate physical forces simultaneously to remove dirt and grime, followed by the second cleaning process involving two more separate physical forces simultaneously, it is possible to further enhance the effectiveness of removing dirt, burrs, and scale from the object being cleaned (60).
