Description

  The present invention relates to a radiator coolant regenerating apparatus and a regeneration method for extracting and regenerating coolant for a vehicle engine such as an automobile.

A water-cooled engine mounted on an automobile transmits heat generated by the engine to a coolant, and dissipates this heat from a radiator (radiator) to the atmosphere. By the way, conventionally, the coolant has been replaced by removing the cap of the radiator coolant inlet (radiator filler) and the drain plugs of the engine and the radiator, discharging old coolant from both drains, and using tap water to circulate the radiator. After cleaning, the drain plugs are respectively attached, and then, new coolant is filled into the engine and the radiator from the coolant inlet of the radiator. However, in order to discard the old liquid extracted from the radiator, it takes time and effort to perform a predetermined dilution process. Therefore, it is preferable that the waste amount of the old liquid is as small as possible. In view of this point, Patent Document 1 discloses a technique in which old liquid extracted from a radiator is temporarily stored in a cushion tank, filtered and regenerated by a predetermined amount, filled again in the radiator, and used. .
JP-A-2005-22739

  In the technique disclosed in Patent Document 1, the regeneration container is separated into a cushion tank for adding an additive for regeneration treatment and a filtration container in which a filter for filtration is disposed. Even if the amount of the old liquid drawn out increases or decreases, the amount of the regenerated liquid to be refilled can be stabilized because it can be temporarily stored in the cushion tank. However, since the cushion tank and the filtration container are separated, the piping path connecting them is complicated, and the old liquid remains in these piping paths after the regeneration process. If the radiator coolant is replaced for a car of another manufacturer while the old liquid remains, the coolant is usually colored in a different color depending on the manufacturer, so the color of the regenerated coolant is filled in the car. The color of the original coolant will be different. For this reason, it is desirable to discharge the old liquid remaining in the system of the regeneration apparatus every time the regeneration process is performed, but even in that case, the one described in Patent Document 1 is exhausted because the piping path is complicated. The amount of old liquid is relatively large. In addition, since the cushion tank is provided, it is possible to cope with an increase or decrease in the amount of old liquid drawn from the radiator. However, before starting the regeneration process, it is necessary to store priming water in the cushion tank in advance. When the amount of the old liquid stored in the inside becomes a predetermined amount or more, this must be discharged, which is also a factor that increases the amount of old liquid discarded.

  The present invention has been made in view of the above, and it is possible to reduce the amount of liquid remaining in the piping path, and it is not always necessary to use priming water, and the waste amount of the old liquid (cooling liquid) can be further reduced. It is an object to provide a regeneration device and a regeneration method for a radiator coolant.

In order to solve the above-mentioned problem, in the present invention according to claim 1, a regeneration container provided with a filter for filtration inside,

According to a second aspect of the present invention, there is provided the radiator coolant regenerating apparatus according to the first aspect, wherein the pressurizing / depressurizing means is an air cylinder.

Insert a connecting tube formed of a double cylinder structure consisting of an inner cylinder and an outer cylinder, with the inner cylinder tip protruding beyond the outer cylinder tip, and insert the tip of the inner cylinder into the old liquid in the radiator And attached to the radiator filler of the radiator, the old liquid suction pipe is connected to the inner cylinder of the connecting pipe, the regeneration liquid supply pipe is connected to the outer cylinder of the connecting pipe, and the inner cylinder is connected to the inside of the radiator. Provided is a method for regenerating a radiator cooling liquid, wherein the old liquid is directly sucked and the regenerating liquid is fed into the radiator from the outer cylinder .
According to a fourth aspect of the present invention, there is provided the method for regenerating a radiator coolant according to the third aspect , wherein the pressurizing / depressurizing means is implemented using an air cylinder .

  The present invention has a configuration in which an old liquid suction pipe and a regenerated liquid supply pipe are connected to a regeneration container via a check valve, and the regeneration container is connected to a pressurizing / depressurizing means. For this reason, when the regeneration container is decompressed, the check valve of the regeneration liquid supply pipe is closed, so that the old liquid is sucked only from the old liquid suction pipe, and the old liquid is filtered by the filter and pressurized. In this case, since the check valve of the old liquid suction pipe is closed, the regeneration liquid filtered in the regeneration container is filled into the radiator from the regeneration liquid supply pipe. That is, the present invention has a configuration in which the old liquid sucked into the regeneration container is regenerated and refilled in the radiator, and the piping path is extremely simplified. Therefore, the amount of old liquid (cooling liquid) remaining in the piping path and the regeneration container is extremely small. Further, since the configuration is simple, the cost is low. In addition, since the pressurizing / depressurizing means is connected to the regeneration container, the regeneration process can be performed even if the regeneration container is not necessarily filled with a new liquid as priming water in advance, and the amount of waste liquid corresponding to that can be reduced.

  Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings. FIG. 1 is a diagram schematically showing the overall structure of the playback apparatus 1 of the present embodiment. As shown in this figure, the regenerator 1 of this embodiment includes a regenerator container 10, a connecting pipe 20, an old liquid suction pipe 30, a regenerated liquid supply pipe 40, and a pressurizing / depressurizing means 50. Configured.

  The regeneration container 10 is a sealed container, and a filter 11 for filtration is disposed inside. The structure of the filter 11 is not limited. For example, the filter 11 is formed in a cylindrical shape, and impurities such as rust contained in the old liquid are removed by passing the old liquid from the outside to the inside with respect to the peripheral wall. It is what is done. The inside of the regeneration container 10 is divided into an untreated old liquid side and a filtered regenerated liquid side through the filter 11, and an old liquid introduction port 12 is provided on the old liquid side. A discharge port 13 is provided. The regeneration container 10 is connected to a pressurizing / depressurizing pipe 51 of the pressurizing / depressurizing means 50. The pressurizing / depressurizing means 50 may be composed of separate devices for the pressurizing source and the depressurizing source. However, when an air cylinder capable of pressurizing and depressing only by reciprocating operation of the piston is used. It is preferable because the structure is simple and the equipment cost can be reduced. However, any power may be used for reciprocating the piston 52 of the air cylinder, and air pressure, hydraulic pressure, electric power, or the like can be used.

The connecting pipe 20 has a connecting portion 23 that can be attached to the radiator filler 101 of the radiator 100. In the present embodiment, the connection pipe 20 is formed in a double cylinder structure of an inner cylinder 21 and an outer cylinder 22 as shown in FIG. Of these, the inner cylinder 21 has a distal end portion 21 b protruding from the distal end portion 22 b of the outer cylinder 22, and can be sucked into the old liquid directly by being inserted into the radiator 100. That is, in this embodiment, the inner cylinder 21 is used for sucking in old liquid, and the outer cylinder 22 is used for supplying regeneration liquid. Such a configuration is preferable for reliably sucking in the old liquid .

  The old liquid suction pipe 30 is connected to the other end of the inner cylinder 21, and the regenerative liquid supply pipe 40 is connected to the other end of the outer cylinder 22. The inner cylinder 21 and the old liquid suction pipe 30, and the outer cylinder 22 and the regenerated liquid supply pipe 40 may be configured by separate members as described above. The suction pipe 30 may be formed of a single cylindrical body, and the outer cylinder 22 and the regenerative liquid supply pipe 40 may be formed of a single cylindrical body, and may be branched in the middle. The other end of the old liquid suction pipe 30 is connected to the old liquid inlet 12 of the regeneration container 10 via a check valve 31 that allows only the flow from the radiator 100 side to the regeneration container 10 side. Further, the other end of the regeneration liquid supply pipe 40 is connected to the regeneration liquid discharge port 13 of the regeneration container 10 via a check valve 41 that allows only the flow from the regeneration container 10 side to the radiator 100 side.

  In regenerating the coolant in the radiator 100 in the present embodiment, first, the connecting portion 23 of the connecting pipe 20 is connected to the radiator filler 101, and the tip of the inner cylinder 21 is inserted into the old liquid in the radiator 100. . In this state, the pressurizing / depressurizing means 50 is operated, for example, the piston 52 of the air cylinder is pulled, and the inside of the regeneration container 10 is depressurized. As a result, the old liquid in the radiator 100 is sucked up. However, since the regenerative liquid supply pipe 40 is provided with a check valve 41 for blocking liquid intrusion from the radiator 100 side, Is not sucked up, but is sucked up only from the old liquid suction pipe 30 through the inner cylinder 21. The old liquid is introduced from the old liquid suction pipe 30 to the untreated side in the regeneration container 10 through the old liquid inlet 12, and is filtered by passing through the filter 11.

  Next, when the pressurizing / depressurizing means 50 is operated and, for example, the piston 52 of the air cylinder is pushed in, the inside of the regeneration container 10 is pressurized, and the regenerated liquid filtered by passing through the filter 11 is pushed out. . At this time, since the check valve 31 of the old liquid suction pipe 30 is closed, the regenerated liquid is sent to the regenerated liquid supply pipe 40 through the regenerated liquid discharge port 13, and further through the outer cylinder 22 to the radiator 100. Filled in.

  As described above, according to the present embodiment, the old liquid can be sucked up and filtered by only the operation of the pressurizing / depressurizing means 50 connected to the regeneration container 10 and filled into the radiator 100 as the regenerated liquid. Therefore, there are only a pipe line through which the liquid passes, the connecting pipe 20, the old liquid suction pipe 30 and the regenerated liquid supply pipe 40, and the configuration is very simple, and the amount of liquid remaining after the completion of the regenerating process is small. Further, since the old liquid is forcibly extracted by the pressurizing / depressurizing means 50, filtered, and re-supplied, basically no priming water is required, but some amount of water is previously placed in the regeneration container 10 in advance. It may be filled with a new solution. In this case, although the amount of waste liquid increases somewhat, since the new liquid can be filled, the composition and concentration of the cooling liquid in the radiator 100 after the regeneration process is more preferable. Although not shown, the regeneration container 10 may be configured such that, for example, a regeneration additive can be added to the untreated side where the old liquid is introduced.

  In the present embodiment, the connection pipe 20 is removed from the radiator filler 101 when the regeneration process is completed. And the front-end | tip part 21b, 22b of the inner cylinder 21 and the outer cylinder 22 is inserted in an oil jug (not shown) etc., and the pressurization / decompression means 50 is operated and pressurized. Thereby, the liquid remaining in the filter 11 of the regeneration container 10, the old liquid suction pipe 30, the regeneration liquid supply pipe 40, and the connection pipe 20 is discharged. At this time, according to the present embodiment, the piping configuration is simple and the amount of liquid remaining in the piping system is small, so that the amount of waste liquid is extremely small.

  When the apparatus described in Patent Document 1 and the apparatus of this embodiment were used to regenerate the coolant in the radiator 100 and the amount of liquid remaining in each apparatus was examined after the work was completed, Patent Document 1 The described apparatus was a total of 400 g of the amount of impregnating liquid in the filter 200 g and the amount of residual liquid 200 g in the piping path, whereas the apparatus of the present embodiment is 30 g of the impregnating liquid amount in the filter and 10 g of residual liquid amount in the piping path. It was found that the residual liquid amount of the apparatus of this embodiment was extremely small.
