Description

  The present invention relates to a vehicular coolant regenerating apparatus for extracting a coolant from a vehicle engine such as an automobile from a cooling water system such as a radiator and performing a regeneration process.

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, replacement of the coolant has been done by removing the cap of the coolant inlet (radiator filler) of the radiator and the drain plugs of the engine and the radiator, and discharging the old coolant from both drains, and using tap water in the radiator. Next, the drain plugs are respectively mounted, and new coolant is filled into the engine and the radiator from the coolant 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 once stored in a cushion tank, filtered and regenerated by a predetermined amount, and filled again into the radiator for use. .
JP-A-2005-22739

  In the technique disclosed in Patent Document 1, the old liquid in the radiator is pushed out by a pump, the old liquid that has been pushed out is brought into contact with a regenerating additive in a cushion tank that is open to the atmosphere, and further filtered through a filtration container.

The system including the vehicle coolant regenerator of the invention has a substantially sealed path during the operation of the pressurizing / depressurizing means. Thus, the old liquid is sucked into the filtration container and filtered when the pressure is reduced by the pressurizing / depressurizing means. That is, it is not a configuration in which the regeneration solution is fed and the old solution is pushed out as in the conventional case, but the old solution is actively sucked in, so that the filter passage time (filtering time) can be shortened and captured by the filter. The amount of the remaining liquid is reduced, and the cooling liquid replacement efficiency can be increased. Further, in the present invention, the additive filling mechanism is connected to the regenerated liquid storage container that holds the regenerated liquid subjected to the filtration treatment, and the additive is added to the regenerated liquid after the filtration treatment. The additive is effectively used without being captured by the filter for filtration while adhering.

  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 vehicle coolant regenerator 1 of the present embodiment. As shown in this figure, the regenerator 1 of the present embodiment is configured to include a filtration container 10, a regenerative liquid storage container 20, and pressurizing / depressurizing means 30.

  The filtration container 10 is composed of 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 by passing the old liquid from the outside to the inside of the peripheral wall, rust, metal ion aggregates, and the like contained in the old liquid Impurities are removed. The inside of the filtration container 10 is divided into an untreated old liquid side positioned outside the peripheral wall and a filtered regenerated liquid side positioned inside the peripheral wall, with the peripheral wall of the filter 11 being separated. A liquid inlet 12 is provided, and a regeneration liquid outlet 13 is provided on the regeneration liquid side.

  One end of the old liquid intake pipe 40 is connected to the old liquid inlet 12 of the filtration container 10. The other end of the old liquid intake pipe 40 is connected to the radiator 100 or the reservoir tank 110 constituting the cooling water system of the vehicle. In the present embodiment, the other liquid intake pipe 40 is connected to these via a connection pipe 50 described later. One end of a regeneration liquid intake pipe 41 is connected to the regeneration liquid outlet 13, which will be described later.

  The regeneration solution storage container 20 has a regeneration solution outlet 21. One end of a regenerant liquid inflow / outflow pipe 42 is connected to the regenerant liquid outflow inlet 21. A branch part 43 is provided on the other end side of the regenerative liquid inflow / outflow pipe 42, and the other end of the regenerative liquid intake pipe 41 having one end connected to the filtration container 10 is connected to the branch part 43. Further, one end of the regenerative liquid supply pipe 44 connected to the radiator 100 or the reservoir tank 110 constituting the cooling water system of the vehicle is connected to the branch portion 43 via a connection pipe 50 described later. A first check valve 41 a is disposed between the branch part 43 and the regeneration liquid outlet 13 of the filtration container 10 in the regeneration liquid intake pipe 41, and is connected to the branch part 43 in the regeneration liquid supply pipe 44. A second check valve 44 a is disposed between the pipe 50 and the second check valve 44 a. The first check valve 41a is set so as to allow inflow of the regenerated liquid from the filtration container 10 side to the regenerative liquid inflow / outflow pipe 42 side at the time of depressurization and prevent back flow to the filtration container 10 side at the time of pressurization. The second check valve 44a allows the regeneration liquid to flow from the regeneration liquid inflow / outflow pipe 42 side to the regeneration liquid supply pipe 44 side during pressurization, and to the regeneration liquid outflow / inflow pipe 42 side during decompression. It is set to prevent backflow. In the present embodiment, when the coolant regeneration process is performed by driving the pressurizing / depressurizing unit 30, the system of the regeneration apparatus 1 is substantially sealed. For this reason, a pressure relief valve 44 b is provided at an appropriate place, in the present embodiment, in the middle of the regenerative liquid supply pipe 44 for safety when the system pressure becomes too high.

  Here, in the present embodiment, the regenerated liquid filtered by the filtration container 10 passes through the regenerative liquid inflow / outflow pipe 42 from the regenerated liquid intake pipe 41 through the branch portion 43 during decompression, and then regenerated liquid storage container 20. At the time of pressurization, the regenerated liquid storage container 20 flows out into the regenerated liquid inflow / outflow pipe 42 and is sent to the regenerated liquid supply pipe 44 through the branch portion 43. That is, the regenerative liquid inflow / outflow pipe 42 connecting the branch portion 43 and the regenerative liquid outflow inlet 21 of the regenerative liquid storage container 20 is configured to allow the regenerative liquid to pass both during decompression and pressurization. Accordingly, it is only necessary to form one regenerative liquid inflow / outlet 21 in the regenerative liquid storage container 20, which simplifies the configuration. Instead of using the unit 43, it is possible to directly connect the regenerating liquid intake pipe 41 to the former and the regenerating liquid supply pipe 44 to the latter.

  The regenerative liquid storage container 20 is provided with a water level detection sensor for detecting the water level of the regenerated liquid stored. In the present embodiment, the pressurizing / depressurizing means 30 is connected to the regenerative liquid storage container 20, and the regenerative liquid storage container 20 is pressurized or depressurized to supply the regenerative liquid and take in the old liquid. When the amount of liquid in the storage container 20 is too small, it is difficult to perform a pressurizing operation, and when the amount of liquid is too large, it is difficult to perform a depressurizing operation. For this reason, it is provided to detect the amount of liquid in the regenerative liquid storage container 20 and adjust the timing of the pressurization operation and the decompression operation so as to keep the neutral position as much as possible within the upper and lower limits. In this embodiment, a float 25 containing a magnet is arranged, and proximity switches 26 and 27 are arranged corresponding to the upper limit position and the lower limit position of the liquid level, respectively, and the float 25 is raised or lowered. When the upper limit position or the lower limit position is reached, the proximity switch 26 or 27 detects them, and the detection signal is sent to the control device 34 of the pressurizing / depressurizing means 30 to perform predetermined control. The water level detection sensor is not limited to the one using the float 25 and the proximity switches 26 and 27, and other types of liquid level gauges or pressure sensors can be used.

  A pressurizing / depressurizing means 30 is connected to the regenerated liquid storage container 20. The configuration of the pressurizing / depressurizing means 30 is not limited as long as the pressurizing / depressurizing in the regenerated liquid storage container 20 can be performed. The pressurizing / depressurizing means 30 of the present embodiment includes a compressor 31 that sends a high-pressure fluid (for example, high-pressure air), a regulator 32, an ejector 33, electromagnetic valves SV1 to SV3, and a control device 34 that performs drive control thereof. Composed. When the control device 34 closes the solenoid valves SV3 and SV2 and opens the solenoid valve SV1, high-pressure air is sent into the regenerated liquid storage container 20 and pressurized. When the solenoid valve SV1 is closed and the solenoid valves SV2 and SV3 are opened, the high-pressure air is discharged from the ejector 33, so that the air in the regenerated liquid storage container 20 is sucked through the solenoid valve SV2 and depressurized. The

  Further, an additive filling mechanism 60 is connected to the regenerated liquid storage container 20. The additive filling mechanism 60 includes a chemical charging container 61 for charging an additive for regeneration, a charging pipe 62 provided between the chemical charging container 61 and the regenerated liquid storage container 20, and an intervening pipe 62. And an electromagnetic valve SV4 provided. The solenoid valve SV4 is controlled to be opened and closed by the controller 34 of the pressurizing / depressurizing means 30 described above. Specifically, when adding the additive, the pressurizing / depressurizing means 30 is driven, the electromagnetic valve SV1 is closed, and the electromagnetic valves SV2, SV3 and SV4 are opened. When the compressor 31 is driven in this state, the inside of the regenerated liquid storage container 20 is depressurized, so that the additive is sucked from the chemical charging container 61 and charged into the regenerated liquid storage container 30. The additive filling mechanism 60 may be connected to the filtration container 10 and may be configured to add the additive to the old liquid before the filtration treatment. In this case, the additive is included in the old liquid. If it adheres to rust or the like and is captured by the filter 11 as it is, waste may occur. Therefore, it is preferable to use a configuration in which the additive is added to the regenerated liquid after the filtration treatment as in this embodiment because the additive is not wasted and can be effectively used.

  The connecting pipe 50 includes a connecting portion 53 having a shape and a structure that can be attached to the radiator filler 101 of the radiator 100 that constitutes the cooling water system of the vehicle. In the present embodiment, the connection pipe 50 is formed in a double cylinder structure of an inner cylinder 51 and an outer cylinder 52 as shown in FIG. Among these, the inner cylinder 51 has a front end portion 51 b protruding from the front end portion 52 b of the outer cylinder 52, and the old liquid can be directly sucked by being inserted into the radiator 100. That is, in this embodiment, the inner cylinder 51 is used for sucking in old liquid, and the outer cylinder 52 is used for supplying regeneration liquid. Such a configuration is preferable for reliably sucking in the old liquid. However, as disclosed in JP-A-2002-70556, the inner cylinder 51 is used for supplying the regeneration liquid, and the outer cylinder 52 is used for sucking the old liquid. It can also be used.

  An old liquid intake pipe 40 is connected to the other end of the inner cylinder 51, and a regeneration liquid supply pipe 44 is connected to the other end of the outer cylinder 52. The inner cylinder 51 and the old liquid intake pipe 40, and the outer cylinder 52 and the regenerated liquid supply pipe 44 may be configured by separate members as described above. The intake tube 40 is composed of a single conduit, and the outer cylinder 52 and the regenerating liquid supply tube 44 are composed of a single conduit, and the structure can be divided in the middle.

  Next, a procedure for regenerating and replacing the coolant in the vehicle cooling system using the vehicle coolant regenerating apparatus 1 of the present embodiment will be described. First, as a preparatory process before starting the regeneration process of the coolant (old liquid) in the radiator 100, the solenoid valve SV1 is closed, the solenoid valves SV4, SV2, SV3 are opened, and the compressor 31 is driven to perform suction. . As a result, the additive in the chemical charging container 61 is charged into the regenerated liquid storage container 20 through the charging pipe 62. The input amount is controlled by, for example, driving time (for example, 10 seconds).

  Next, the cooling liquid (old liquid) in the reservoir tank 110 is extracted. At this time, both the old liquid intake pipe 40 and the regenerated liquid supply pipe 44 may be connected to the connection pipe 50 and the tip of the inner cylinder 51 may be inserted into the reservoir tank 110 and removed. When extracting from the reservoir tank 110, the old liquid intake tube 40 is connected to an extraction tube 46 dedicated to the reservoir tank 110 (see FIG. 1). As a result, the connecting pipe 50 may be kept connected to the radiator filler 101, and the labor of moving the connecting pipe 50 between the radiator filler 101 and the insertion port of the reservoir tank 110 can be saved.

  With the old liquid intake pipe 40 connected to the extraction tube 46, the solenoid valves SV1 and SV4 are closed, the solenoid valves SV2 and SV3 are opened, the compressor 31 is driven and air is discharged from the ejector 33 to regenerate the liquid. The inside of the storage container 20 is depressurized. Thereby, the old liquid in the reservoir tank 110 is taken into the filtration container 10 via the old liquid intake pipe 40, and further filtered through the filter 11 disposed inside from the outside to the inside. The regenerated liquid storage container 20 is aspirated. The old liquid in the reservoir tank 110 is extracted until the water level in the regenerated liquid storage container 20 is detected by the upper limit proximity switch 26. Since the regeneration additive has already been introduced into the regeneration liquid storage container 20, the filtered regeneration liquid flowing into the regeneration liquid storage container 20 is processed in contact with the additive. In addition, as an additive for reproduction | regeneration, what contains azoles, phosphoric acid, a phosphate, etc. can be used.

  When the preparation step is completed, the old liquid intake tube 40 is connected to the inner cylinder 51 of the connection tube 50. The connecting pipe 50 connects the connecting portion 53 to the radiator filler 101 and inserts the tip of the inner cylinder 51 into the old liquid in the radiator 100. In this state, the pressurizing / depressurizing means 30 is operated. First, the solenoid valve SV1 is opened, all the other solenoid valves SV2 to SV4 are closed, and the high-pressure air of the compressor 31 is sent to the regenerating liquid supply container 20. As a result, the regenerated liquid in the regenerated liquid supply container 20 cannot flow into the filtration container 10 by the first check valve 41a after passing through the regenerated liquid inflow / outflow pipe 42, and therefore flows into the regenerated liquid supply pipe 44. Further, the radiator 100 is filled through the outer cylinder 52 of the connection pipe 50. Next, when the solenoid valve SV1 is closed, the solenoid valves SV2 and SV3 are opened, and high pressure air is allowed to flow to the ejector 33 side, the inside of the regenerated liquid storage container 20 is decompressed. As a result, the old liquid in the radiator 100 does not flow into the regenerated liquid supply pipe 44 because the second check valve 44 a is provided in the regenerated liquid supply pipe 44, and the inner cylinder 51 of the connection pipe 50. And it is taken in into the filtration container 10 through the old liquid taking-in pipe 40, and is forced through the filter 11 from the outside to the inside to be filtered. In this embodiment, since the old liquid is sucked and filtered in this way, the filter 11 can be quickly passed, and the processing time can be made longer than in the case where the same amount is circulated in one direction only by pressurization. Can be shortened.

  The filtered regenerated liquid is further sucked into the regenerated liquid storage container 20 via the regenerated liquid intake pipe 41 and the regenerated liquid inflow / outflow pipe 42 and is brought into contact with the additive. In this state, when the solenoid valve SV1 is opened and the solenoid valves SV2 and SV3 are closed in the same manner as described above, the inside of the regenerated liquid storage container 20 is again pressurized, and the regenerated liquid flows into the regenerated liquid inflow / outflow pipe 42 and the regenerated liquid supply pipe. 44 and the outer cylinder 52 of the connecting pipe 50 are filled into the radiator 100. Next, when the solenoid valve SV1 is closed and the solenoid valves SV2 and SV3 are opened, the pressure is reduced again and the old liquid is sucked. Thereafter, pressurization and decompression are repeated.

  Pressurization and decompression are performed by switching the solenoid valves SV1 to SV4 by timer control by the control device 34. Normally, pressurization and depressurization are repeated by timer control, but if it is detected that the water level of the regenerative liquid storage container 20 has reached the lower limit by the proximity switch 27, the detection signal is sent to the control device 34, When the solenoid valves SV1 to SV4 are switched to pressure reducing operation to raise the water level and the proximity switch 26 detects that the upper limit is reached, the detection signal is sent to the control device 34, and the solenoid valves SV1 to SV4 are turned on. Switch to pressurization operation to lower the water level.

  By repeating the pressurizing operation and the depressurizing operation for a predetermined time, the old liquid in the cooling water system including the radiator 100 is replaced with the regenerated liquid. When the regeneration process is completed, the connecting pipe 50 is removed from the radiator filler 101. Then, the distal ends of the connecting pipe 50, that is, the distal end portions 51b and 52b of the inner cylinder 51 and the outer cylinder 52 are inserted into the oil mug 200 or the like, and the pressurizing / depressurizing means 30 is operated to perform the pressurizing operation and the decompressing operation. Conduct again for a predetermined time. Thereby, the liquid remaining in the filter 11 of the filtration container 10, the old liquid intake pipe 40, the regenerated liquid supply pipe 44, the connection pipe 50, and the like is discharged. At this time, according to the present embodiment, the liquid is discharged under pressure and pressure reduction, so that there is little liquid remaining while being held in the filter 11 or the like.

  In the above embodiment, the pressure relief valve 44 b is provided in the middle of the regenerated liquid supply pipe 44 in case the system pressure becomes too high. However, when the pressure relief valve 44b is opened and the regeneration liquid actually flows out, the operation of the regeneration device 1 may not be smooth depending on the amount of the regeneration liquid flowing out. In order to prevent such a situation, when the pressure relief valve 44b is opened and the regenerated liquid flows out, it is preferable to return the regenerated liquid that has flowed out into the system of the regenerator 1. The return position is arbitrary, but in the above-described embodiment, since the additive filling mechanism 60 capable of adding the additive into the system of the regenerator 1 is provided, it is preferable to use the additive filling mechanism 60. That is, when the regenerated liquid is returned to the chemical charging container 61 of the additive charging mechanism 60, the electromagnetic valve SV1 is closed and the electromagnetic valves SV2 and SV3 are specifically closed in the same procedure as when the additive is charged. And SV4 is opened and the compressor 31 is driven in this state, whereby the regenerated liquid can be returned into the system of the regenerator 1.

  As a means for returning the regenerated liquid that has flowed out by opening the pressure relief valve 44b to the chemical charging container 61, for example, the regenerated liquid is received by the oil mug 200 shown in FIG. 1 and poured into the chemical charging container 61 manually. However, as shown in FIG. 3, a regenerated liquid reflux pipe 70 is disposed between the pressure relief valve 44b and the chemical charging container 61, and the pressure relief valve 44b flows out of the hands without being manually handled. It is preferable that the regenerated liquid automatically returns to the chemical charging container 61.

  In the above description, the pressure process is first performed after suctioning to near the upper limit in the regenerated liquid storage container 20, and then the pressure reduction and pressure increase are repeated. Is not limited to this.
