Cleaning liquid supply device

The present invention relates to a cleaning liquid supply device which can use tap water, well water, or the like, and is added as a cleaning liquid to improve the sterilization and deodorizing effect, and pressurize and output the high pressure pump.

In recent years, most of the urban and its suburban areas have been built as high-rise buildings in the form of high-rise buildings. The domestic drainage (sewage) discharged from the assembly type of the building is discharged to the external transverse pipe through a dedicated drain pipe installed in the house. The way to maintain a good living environment.

Here, since the above-mentioned domestic sewage contains a large amount of residue, oil, and the like, these may adhere to the wall of the drain pipe to form a solid matter, which causes a pathogen or a bad smell, and causes a significant living environment. The problem of deterioration. Moreover, since solid objects adhering to the pipe wall sometimes cause problems such as clogging of the drain pipe, it is necessary to periodically clean the dedicated drain pipe and the shared drain pipe.

As described above, in order to remove the solid matter adhering to the drain pipe, various powerful washing methods have been proposed, one of which is a high-pressure water jet washing method.

The high-pressure water jet cleaning method inserts a flexible hose having a high-pressure water jet nozzle at a front end portion into a drain pipe, and supplies the washing water pressurized by the high-pressure pump to the hose, and by the foregoing The nozzle sprays the washing water while performing the operation of advancing inside the drain pipe.

Therefore, the solid matter or the like adhering to the drain pipe can be crushed or peeled off by the injection pressure of the washing water from the high-pressure water jet nozzle.

Regarding the high-pressure water jet washing method in the above-mentioned drain pipe, and the high-pressure water jet nozzle and the like using the same, all of the applicants of the present invention have been proposed, and are disclosed in Japanese Laid-Open Patent Publication No. 2002-275984 and No. 2008-163644. Bulletin and so on.

In addition, in the case of the washing water used for the washing of the above-mentioned drain pipe, it is proposed to add a chemical liquid for the purpose of improving the effect of sterilization and deodorization. For example, an inorganic alkali preparation such as sodium chlorite or the like has been proposed, or An inorganic acid such as hydrochloric acid is added thereto and used as a cleaning liquid. This is disclosed in Japanese Laid-Open Patent Publication No. 2010-150319.

Here, the above-described cleaning liquid is configured to be temporarily stored in the cleaning liquid storage tank provided in the cleaning liquid supply device, and is pressurized by a high-pressure pump driven by the engine power of the internal combustion engine, and the self-injection nozzle The washing liquid supply device is set to have, for example, the ability to simultaneously supply the washing liquid to about three injection nozzles. At this time, depending on the degree of progress of each work, there is a case where the washing liquid is discharged from the three jet nozzles at the same time, or the washing liquid is not discharged from any of the jet nozzles.

As described above, depending on the discharge state of the cleaning liquid from each of the ejection nozzles or the difference in the discharge amount of the cleaning liquid of each of the ejection nozzles, the high-pressure cleaning liquid outputted from the high-pressure pump side is constantly changed. The amount. Further, irrespective of the amount of discharge of the cleaning liquid in the high pressure pump, it is necessary to maintain a certain discharge pressure of the cleaning liquid.

Further, in the cleaning liquid output unit, generally, the residual water passage is formed so that the residual moisture of the washing liquid pressurized by the high pressure pump is returned to the storage tank.

Therefore, in the operation of the above-described cleaning liquid output unit, when the cleaning liquid is discharged from a small number of injection nozzles, or is not discharged from any of the injection nozzles In the case of the cleaning liquid, most or the entire amount of the washing liquid pressurized by the high pressure pump is returned to the washing liquid storage tank. In other words, the cleaning liquid circulates between the high pressure pump and the cleaning liquid storage tank through the piping of the aforementioned residual water passage.

At this time, since the cleaning liquid passes through the high-pressure pump, it is subjected to high-pressure energy due to compression, and the temperature thereof rises. When the cleaning liquid having the temperature rise is continuously discharged through the above-described injection nozzle, there is no problem, but the cleaning liquid from the high pressure pump is returned to the cleaning liquid storage tank through the piping of the residual water passage described above. When the amount is increased, the temperature of the washing liquid in the washing liquid storage tank rises due to heat storage.

When the temperature of the washing liquid rises as described above, there is a problem that the worker is in danger of being burnt due to accidental contact with the washing liquid by the worker during the washing operation. In addition, in order to improve the sterilization and deodorizing effect, for example, when a chemical solution such as sodium hypochlorite or hydrochloric acid is added to tap water to be used as a cleaning liquid, the temperature of the washing liquid rises. Increasing the chance of generating chlorine, etc., causes problems such as deterioration of the working environment.

The present invention has been made in view of the above problems, and provides a cleaning liquid output unit for outputting a cleaning liquid by a high pressure pump, irrespective of the discharge amount of the cleaning liquid from the injection nozzle, which can be adopted by the foregoing. In the piping of the residual water passage, the amount of the cleaning liquid which is returned to the washing liquid storage tank is extremely small, and the cleaning liquid supply device capable of suppressing the temperature rise of the washing liquid in the washing liquid storage tank is a problem. .

Further, in addition to the above-described effects, the present invention can be manufactured by using a dilution mixing tank in a cleaning liquid generating unit which is provided by adding a chemical solution to a cleaning liquid to form a cleaning liquid.

To increase the amount of water supplied, the washing liquid in the washing liquid storage tank is discharged as blow water.

In this case, the preferred chemical solution dilution mixing tank is configured to: a pH sensor disposed in the mixing tank to measure the pH of the cleaning liquid, and based on the pH value obtained by the pH sensor. The amount of the chemical liquid added to the chemical liquid dilution mixing tank is controlled.

In a more preferred embodiment, the method is configured to: provide a float sensor for detecting the amount of the cleaning liquid in the cleaning liquid storage tank, and The liquid amount detecting information obtained by the floating ball sensor controls the water supply valve to control the amount of washing water supplied into the chemical liquid dilution mixing tank, and is configured to: the liquid amount obtained by the floating ball sensor When the detected value reaches the specified value, the control of the water supply in the dilution tank of the liquid chemical is stopped by the water supply valve.

Comparing the stopping of the water supply by the water supply valve according to the liquid amount detecting information obtained by the floating ball sensor, the optimal one is based on the liquid temperature detecting information obtained by the liquid temperature sensor. The control of increasing the amount of water supplied by the aforementioned water supply valve is implemented.

According to the cleaning liquid supply device of the present invention, the engine is configured to rotate the high-pressure pump depending on the flow rate of the cleaning liquid flowing from the high-pressure pump into the discharge passage of the high-pressure cleaning liquid. Since the number of revolutions is increased or decreased, the amount of residual moisture that flows back from the high-pressure pump to the cleaning liquid storage tank through the residual water passage can be reduced as much as possible.

Therefore, by returning the residual moisture which is pressurized in the high pressure pump and the liquid temperature is raised to the cleaning liquid storage tank, the temperature rise of the cleaning liquid in the storage tank can be effectively suppressed.

Further, it is possible to solve the problem that the temperature of the washing liquid in the storage tank rises to affect the worker's danger, and it is also possible to solve the problem of generating chlorine gas or the like due to, for example, an increase in the temperature of the washing liquid to which the chemical liquid is added.

Therefore, the amount of the cleaning liquid sent from the chemical solution dilution mixing tank T1 to the cleaning liquid storage tank T2 is increased, and the cleaning liquid in the cleaning liquid storage tank T2 is discharged as the blown water 20. Further, by lowering the temperature of the washing liquid in the washing liquid storage tank T2, and detecting that the liquid temperature sensor 18 is lowered to a predetermined value, the solenoid valve 2 is turned off as a water supply valve or the passage is reduced. Control of water quantity.

In addition, the temperature of the cleaning liquid in the cleaning liquid storage tank T2 rises, and the cleaning liquid heated by the high-pressure pump in the cleaning liquid output unit U2 described below is largely returned to the washing water through the residual water passage. The reason for the liquid storage tank T2.

In the cleaning liquid output unit U2 to be described below, the means for suppressing the temperature rise of the cleaning liquid in the cleaning liquid storage tank T2 is performed, but the cleaning liquid in the cleaning liquid storage tank T2 is discharged. In order to blow out the water 20, a means for suppressing an increase in the temperature of the washing liquid is taken as an extraordinary means.

Moreover, with respect to the control of stopping the water supply by the aforementioned water supply valve (solenoid valve 2) based on the detection information of the liquid amount by the aforementioned float sensor 17, the liquid temperature sensor 18 is detected by the foregoing. The liquid temperature rises and the control is performed by opening the water supply valve (electromagnetic valve 2) to increase the amount of water supplied.

Next, the cleaning liquid output unit U2 shown in Fig. 2 is capable of outputting the cleaning liquid in the cleaning liquid storage tank T2 by a high pressure pump and pressurizing it under high pressure.

In Fig. 2, reference numeral 22 denotes the aforementioned high pressure pump, which is a high voltage gang. The PU 22 is driven by, for example, a turning driving force of an engine 23 of an internal combustion engine such as a diesel engine.

The high-pressure pump 22 includes a suction passage 22a that sucks the cleaning liquid in the cleaning liquid storage tank T2, a discharge passage 22b that discharges the high-pressure washing liquid pressurized by the high-pressure pump 22, and a high-pressure pump. The residual moisture in the high pressure washing liquid of 22 is returned to the residual water passage 22c in the washing liquid storage tank T2.

The high pressure pump 22 includes a pressure sensor 24 that measures a pressing force in the high pressure pump 22, and the engine 23 includes a swing sensor 25 that measures the number of revolutions of the engine 23.

Then, the output signals of the pressure sensor 24 and the swing sensor 25 are supplied to the engine controller 27.

Further, a flow switch 28 is disposed in the discharge passage 22b that discharges the high-pressure washing liquid in the high-pressure pump 22, and the discharge valve 29 including the control lever is connected via the flow switch 28. Next, an injection nozzle (not shown) for connecting the cleaning liquid to the discharge valve 29 via a flexible hose is provided.

The flow switch 28 is provided with a function of detecting whether or not the cleaning liquid flows in the discharge passage 22b, and the information is supplied to the engine controller 27.

In addition, FIG. 2 shows a state in which one discharge valve 29 is connected to the flow switch 28. When a plurality of injection nozzles of the cleaning liquid are used, after the flow switch 28, the discharge corresponding to each of the injection nozzles is connected in parallel. Valve 29.

Further, the residual moisture in the high-pressure washing liquid from the high-pressure pump 22 is returned to the residual water passage 22c in the washing liquid storage tank T2, and the solenoid valve 31 that controls the switch by an actuator of a motor or the like is connected. And with the electricity The magnetic valve 31 is connected in parallel to the pressure regulating valve 32.

The engine controller 27 is configured to supply detection information from the pressure sensor 24, the swing sensor 25, and the flow switch 28 as described above, and the engine controller 27 is attached to the engine 23 to supply control signals to the control. The throttle control unit 33 of the number of revolutions of the engine 23 is configured. Further, the engine controller 27 also supplies a control signal to the solenoid valve 31 disposed in the aforementioned residual water passage 22c.

In the cleaning liquid output unit U2 shown in FIG. 2 having the above configuration, the detection information from the flow switch 28 disposed in the discharge passage 22b of the high-pressure cleaning liquid, that is, whether or not the cleaning liquid flows, flows into the discharge passage 22b. The information in the supply engine controller 27.

When there is no flow of the cleaning liquid in the discharge passage 22b, the high-pressure washing liquid is not used. In this case, the engine controller 27 outputs the control to the throttle control unit 33 so that the engine 23 is idling. signal.

At the same time, a signal for controlling the valve opening state is transmitted to the solenoid valve 31 by the aforementioned engine controller 27. Then, the pressure of the high-pressure pump 22 is not applied to the washing liquid which is returned to the cleaning liquid storage tank T2 via the residual water passage 22c, and the liquid temperature of the washing liquid which is returned to the storage tank T2 does not rise.

Further, when the flow switch 28 detects the flow of the cleaning liquid in the discharge passage 22b by the high-pressure cleaning liquid, the engine controller 27 transmits a command to increase the rotation of the engine 23 to the throttle control unit 33. signal.

At this time, the discharge pressure of the cleaning liquid can be manually set in the engine controller 27, and the number of revolutions of the engine 23 can be controlled by the discharge pressure of the manually set (for example, 20 MPa) washing liquid.

This is based on the pressure information of the pressure sensor 24 provided in the high pressure pump 22, and is reversely transmitted back to the engine controller 27 to control the number of revolutions of the engine 23 with the set discharge pressure.

At the same time, by the engine controller 27, a signal for controlling the valve closing state is transmitted to the solenoid valve 31, and residual moisture from the high pressure pump 22 is returned to the foregoing storage via the pressure regulating valve 32 and the residual water passage 22c. Inside the slot T2.

Here, the number of uses of the high-pressure water jet nozzle used in the cleaning operation increases, for example, the flow rate of the washing liquid in the discharge passage 22b, and the pressure sensor 24 provided in the high-pressure pump 22 To reduce the pressure gauge measurement.

When the pressure sensor 24 is used to reduce the pressure measurement value, the engine controller 27 is reversely transmitted back to the engine controller 27 so that the discharge pressure of the cleaning liquid is a predetermined value. Control of the rise in the number of revolutions.

Further, contrary to the above, when the number of uses of the high-pressure water jet nozzle is small, the pressure measurement value of the pressure sensor 24 provided in the high-pressure pump 22 rises, and the pressure gauge value is transmitted back to the engine controller. 27. The control for lowering the number of revolutions of the engine 23 is performed so that the discharge pressure of the washing liquid is a predetermined value.

Further, the output signal of the swing sensor 25 provided in the engine 23 is supplied to the engine controller 27 as described above. In this case, when the engine 23 is in a state in which the idle state is lowered more than the set idle state, for example, it has a function of transmitting a control signal for keeping the throttle control unit 33 in an idling state.

In addition, the engine 23 is set up, for example, by a number of factors. When the number of revolutions is equal to or greater than the number of revolutions, the control signal for reducing the number of engine revolutions is transmitted to the throttle control unit 33. Therefore, the safety of controlling the number of revolutions of the aforementioned engine 23 can be secured.

In this way, the pressure sensor 24 detects the flow rate of the cleaning liquid flowing into the discharge passage 22b from the high pressure pump 23, and depending on the flow rate of the cleaning liquid, the number of revolutions of the engine 23 is increased or With the reduced control, the amount of the cleaning liquid which is returned from the high pressure pump 22 to the cleaning liquid storage tank T2 via the aforementioned residual water passage 22c can be set as small as possible.

Further, in the configuration of the cleaning liquid supply device, the amount of the cleaning liquid that can be stored in the cleaning liquid storage tank T2 through the residual water passage 22c can be reduced by the high-pressure pump 22 receiving the high-pressure energy. The temperature of the washing liquid in the washing liquid storage tank is suppressed from rising.

Thereby, the work safety and the like of the high-pressure water jet nozzle can be ensured, and the individual effects described in the column of the effects of the invention described above can be obtained.
