[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid extractor for a tank truck, which is capable of extracting a fluid such as cooking oil, which solidifies at room temperature, such as lard, from the inside of the tank to a distance.

[0002]

2. Description of the Related Art In tank trucks that carry fluids that solidify at room temperature, such as lard, to prevent the fluids from solidifying,
A tank and a fluid take-out pipe are provided with a function of heating them with hot water heated by an engine radiator, and the liquid in the tank is directly fed to a fluid storage tank through a pipe. This type of tank truck is mainly used for large-volume customers.

Therefore, it is conceivable to use the tank truck of this type for small customers such as restaurants.
However, when there is a distance from the fluid storage tank of the small-lot customer to the stop position of the tank truck, it is naturally necessary to connect a hose to the pipe and feed the fluid into the fluid storage tank through the hose. In this case, the fluid may be cooled by the outside air during the delivery and solidified, and the solidified fluid may be clogged in the hose, making it impossible to deliver the fluid.

Therefore, in reality, small consumers purchase 18 liter cans of lard, etc., open them one by one, take out lard, etc., and use them. In this case, there is a problem that it takes time and trouble to open cans and lard, and it is difficult to process empty cans.

In order to solve the above-mentioned problems, for example, as disclosed in Japanese Utility Model Laid-Open No. 59-16886, a flow meter, a switching valve, a hydraulic pump, etc. are provided in a pipe for taking out fluid in a tank to the outside. A hose reel for winding a fluid take-out hose is attached to the pipe, and a series of these members are sealed with a heat insulating cover, and hot water heated by an engine radiator is used in the heat insulating cover. A fluid extraction device has been proposed for a tank truck that is heated by a hot water heater.

Thus, solidification of the fluid in the hose can be avoided by constantly heating the fluid take-out hose and the hose reel for winding the hose in the warming greenhouse, but once the hose is removed from the hose reel in the warming greenhouse. When it is extended to the outside and the hose is pulled out to the installation position of the customer's fluid storage tank,
The fluid staying in the hose during its withdrawal is cooled by the outside air, and the solidified fluid is clogged in the hose,
It may not be possible to deliver fluid. That is,
The longer the withdrawal distance of the hose, the more the solidification of the fluid in the hose is promoted.

Even though the hose is constantly heated in the warming greenhouse, it is not used when the hose is temporarily pulled out and the fluid in the hose is solidified when the pulling distance is long. This is because the fluid always stays in the hose at any time, that is, while being wound around the hose reel.

If the fluid is not retained in the hose while the hose is wound around the hose reel, the fluid is retained in the hose even when the hose is pulled out to the fluid storage tank and exposed to the outside air during use. Since the hose is not clogged in the hose, the heated fluid in the tank is smoothly delivered to the reservoir through the hose due to the delivery pressure.

[0009]

Therefore, according to the present invention, it is possible to prevent oil and fat from staying in the hose when it is not used, that is, while the hose for supplying fluid is wound around the hose reel. The purpose is to be able to.

[0010]

The structure of the present invention for achieving the above object will be described with reference to the drawings corresponding to the embodiments. Claim 1 of the present invention is that the fluid A in the tank 3 is exposed to the outside. The fluid take-out pipe 7 to be taken out is provided with a fluid take-out mechanism B such as a flow meter 12, a strainer 11 or switching valves 8, 13, 14 and the like, and a fluid take-out hose 18 communicating with the pipe 7 is provided.
A hose reel 17 for winding up the hose reel 17 is provided, and the hose reel 17 is sealed with a heat insulating cover 22.
In the fluid take-out device of a tank truck having a warm air blower 23 for exchanging heat with hot water heated by a radiator 26 of an engine 25 to release hot air in the inside 2, the fluid take-out pipe 7 is used to remove residual liquid air. The configuration is adopted in which the degassing valve 10 is connected to the charging port 32 and is provided in the middle of the pipe 7.

Further, in the second aspect, the deaeration valve 10 interposed in the fluid take-out pipe 7 has a fluid further downstream than the flow meter 12 provided in the fluid take-out pipe 7 on the downstream side thereof. The configuration according to claim 1 is employed, which is connected to the extraction pipe 7 by a bypass pipe 16.

[0012]

In the first aspect of the present invention, the fluid take-out pipe 7 for taking out the fluid A in the tank 3 to the outside is provided with the fluid take-out mechanism B such as the flow meter 12, the strainer 11 or the switching valves 8, 13, 14 and the like. A hose reel 17 for winding a fluid take-out hose 18 communicating with the pipe 7 is provided, the fluid take-out hose 18 is pulled out from the hose reel 17, and the hose 18 is installed to a place where the consumer stores a fluid storage tank 20. The fluid A, which is extended and is solidified at room temperature such as lard, is fed to the storage tank 20, but the fluid take-out pipe 7 and the hose 18 naturally form an integral oil feed passage in this way. Therefore, at the final stage of the fluid A supply operation, the residual liquid removal air inlet 32 is connected to the fluid extraction pipe 7, and the air is supplied from the residual liquid removal air inlet 32 Is above Discharged into the fluid reservoir 20 by the pressure of the air fluid A staying in the hose 18 through the pipe 7 and hoses 18, never to the hose 18 fluid A remains.

After removing the fluid A from the hose 18 in this manner, the hose 18 is wound around the hose reel 17,
Since the hose 18 is installed in the warming greenhouse including the heat insulating cover 22 and the warm air blower 23, only the hose 18 is constantly heated without a fluid staying inside.

Therefore, the fluid take-out hose 18 is again drawn from the hose reel 17, the hose 18 is drawn to the place where the fluid storage tank 20 is installed, and the storage tank 20 is filled with the fluid A that solidifies at room temperature such as lard. Even when the hose 18 is in a gentle heat-retaining state because the hose 18 is pulled out by a long distance or the hose 18 takes a long time to pull out the hose 18 when it is fed, and the hose 18 is cooled considerably by the outside cold air. Since the fluid A does not stay inside, the fluid A naturally does not cause clogging, and the heated fluid in the tank is smoothly fed to the storage tank through the hose by its feeding pressure. It will be.

Further, since the fluid A does not remain or remains only slightly inside the fluid take-out pipe 7 and the hose 18 integral with the pipe 7, the pipe 7 and the hose 18 are heated. The pipe 7 or hose 18 will naturally not be clogged even if the degree of graduation is moderate, so it is more economical than the case where the fluid A (oil and fat) is always retained in the pipe 7 or hose 18 It is possible to prevent the blockage due to the fluid.

By inserting air through the fluid take-out pipe 7 and the hose 18, air is likely to be mixed with the fluid in the pipe, and the accuracy of the flow meter for measuring the flow rate of the fluid may deteriorate. In the present invention, since the deaeration valve 10 is provided in the middle of the pipe, if air is mixed in the fluid flowing through the pipe, the air is removed by the deaeration valve 10 during the flow, and the flow meter It is possible to prevent deterioration of the accuracy of.

Furthermore, by discharging the fluid A in the pipe 7 and the hose 18 to the outside by air before reuse, for example, the tank of the tank truck is divided into a plurality of chambers by partition walls, and each tank has a different type. When the above fluid is mounted, it has an additional effect that it can be fed by pipes and hoses without mixing a plurality of fluids.

Further, the heat of combustion of the engine 25 is used as the heat source of the warm air blower 23, and it is economical because no special heating means is required.

According to a second aspect, the fluid take-out pipe 7
The deaeration valve 10 interposed in the pipe 7 is connected to the fluid take-out pipe 7 further downstream of the flow meter 12 provided in the fluid take-out pipe 7 on the downstream side by the bypass pipe 16, The air mixed in the fluid A is the flow meter 1
Since it is discharged to the pipe 7 on the downstream side of the flowmeter 2, the accuracy of the flow meter 12 is not deteriorated.

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a tank lorry vehicle which is an embodiment of the present invention, in which a driver's seat 2 is formed at the front of a loading platform 1 and a tank 3 is placed on the loading platform 1. , The tank is divided into front and rear two chambers 3a and 3b by a partition wall 4, and the fluid A stored in each of the chambers 3a and 3b (see FIG. 2).
A fluid take-out device 5 for taking out (see FIG. 2) is provided on the cargo bed 1.

The fluid take-out device 5 will be described.
As shown in FIG. 2, the fluid take-out pipe 7 whose one end communicates with the bottom valves 6 and 6 with the emergency cutoff valves provided at the bottoms of the chambers 3a and 3b, is connected from the upstream side to the downstream side. Sequentially
The upstream side switching valve 8, the fluid discharge pump 9, the degassing valve 10, the strainer 11, the flow meter 12, the electromagnetic downstream side switching valve 13, and the discharge valve 14 are provided with a fluid extraction mechanism B. Therefore, by opening the valves 8, 13, 14 and operating the fluid discharge pump 9, the chambers 3a, 3
The fluid A taken out from inside b is separated by a deaeration valve 10 into a gas, filtered by a strainer 11, and subsequently a flow meter 1
The flow rate of the fluid A taken out in 2 is displayed, and the fluid is taken out from the discharge port 15 formed at the other end of the fluid taking-out pipe 7, and is mainly used in a large storage tank of a large-scale consumer. It is used when A is sent directly.

The gas separated by the deaeration valve 10 is returned to the fluid A in the fluid extraction pipe 7 downstream of the flow meter 12 via the bypass pipe 16 with the electromagnetic switching valve 16a. And the fluid A
The gas contained in (1) does not pass through the strainer 11 and the flow meter 12. Therefore, the accuracy of the flow meter 12 is not deteriorated.

Further, the switching valve 1 which branches from between the electromagnetic downstream side switching valve 13 of the fluid extraction pipe 7 and the discharge valve 15.
A branch pipe 7a with 9 is connected to a hollow rotary shaft 17a of a hose reel 17 arranged on the loading platform 1 via a rotary joint (not shown), and the hose wound on the hose reel 17 18 is communicated with the fluid extraction pipe 7 through the branch pipe 7a. Therefore, from the state shown by the solid line in FIG.
The hose 18 as shown in the phantom line in FIG.
After inserting the nozzle gun 18a of No. 2 into the opening 20a of the fluid storage tank 20 installed in a restaurant or the like, the discharge valve 14 is closed and the switching valve 19 is opened.
By operating the fluid discharge pump 9, the fluid A can be fed from the chambers 3a and 3b of the tank 3 into the fluid storage tank 20 through the fluid extraction pipe 7, the branch pipe 7a and the hose 18. It is possible and is mainly used when the fluid A is fed to the small-sized storage tank 20 of a small-lot customer.

Further, the hose reel 17 is driven in the hose winding direction by a hydraulic motor (not shown) connected to the output shaft of the tank truck via the gear 21 fitted to the rotary shaft 17a. Has become. The fluid discharge pump 9 is also operated by the driving force of the output shaft.

The hose reel 17 is hermetically sealed by a heat insulating cover 22, and a radiator type warm air fan 23 is arranged in the heat insulating cover 22. The warm air fan 23 is connected to an engine 25 through a hot water circulating pipe 24. It is connected to a radiator 26, and when the engine 25 is started, hot water heated to about 70 to 75 ° C by the radiator 26 is circulated and supplied to the hot air blower 23, and hot air exchanged with the hot water is performed. Is discharged into the heat insulating cover 22 by the fan 23a to heat the hose 18. The fluid take-out pipe 7 and the branch pipe 7a are covered with a jacket 28 which is a double pipe as shown in FIG.
A steam branch pipe 30 a branched from a tank heating steam circulation pipe 30 connected to the hot water circulation pipe 24 via a heat exchanger 29 is connected to the hot water circulation pipe 24.
Steam generated by being heated by the hot water circulating through the heat exchanger 29 is supplied into the jacket 28,
The fluid take-out pipe 7 and the branch pipe 7a are heated.

Therefore, even when a fluid such as lard that is solidified at room temperature is conveyed by a tank truck, the fluid does not solidify in the tank 3, the fluid extraction pipe 7, the branch pipe 7a and the hose 18. . In addition, the fluid discharge pump 9 and the like constituting the fluid take-out mechanism B are similarly covered with the jacket 28 and heated with steam.

According to the above construction, the combustion heat of the engine is used as the heat source, and it is not necessary to use any special heating means, which is economical. In FIG. 1, reference numeral 31 is an operation handle for opening and closing the bottom valve 6. In FIG. 2, 33 is a cleaning liquid inlet, 34 is a water pump, 3
5 is a check valve, 36 is a steam inlet, and 37 is a steam outlet.

Further, in FIG. 2, reference numeral 32 is a residual liquid removal air inlet port, which is connected to the fluid take-out pipe 7. When the fluid A is fed, the inlet port 32 is closed by the valve 32a. ing.

To explain the procedure for taking out the fluid A, which solidifies at room temperature, such as lard, for small customers, the heat exchanger 29 is heated by the hot water heated by the radiator 26 by starting the engine 25 of the tank truck. The steam is generated via the tank 3, and the steam, the tank 3, the fluid extraction pipe 7, the branch pipe 7a, and the fluid discharge pump 9 of the fluid extraction mechanism B are generated.
Etc. As a result, the fluid A stored in them does not solidify. In addition, the hose 1 is heated by the warm air discharged from the warm air blower 23 by heat exchange with the warm water.
Since 8 is also heated, the fluid remaining in it is not solidified. When the fluid A is supplied to the storage tank 20, the hose 18 is pulled out from the hose reel 17 and the nozzle gun 18a is inserted into the opening 20a of the storage tank 20 as shown by the phantom line in FIG. It suffices to operate the pump 9. In this case, the hose 18 is cooled by contact with the outside air, but when the time required to feed the fluid A to the storage tank 20 is extremely short, the hose 18 is fed during the feeding.
The fluid A is not solidified and clogged therein.

At the final stage when the supply of the fluid A to the storage tank 20 is completed, the valve 32a of the residual liquid removal air input port 32 connected to the fluid extraction pipe 7 is opened, and the residual liquid removal air input port 32 is opened. By injecting air, the air passes through the pipe 7 and the hose 18 and discharges the fluid A retained in the hose 18 to the fluid storage tank 20 by the pressure of the air.

After removing the fluid A from the hose 18 in this manner, the hose 18 is wound around the hose reel 17,
Since the hose 18 is installed in the warming greenhouse including the heat insulating cover 22 and the warm air blower 23, only the hose 18 is always heated without oil and fat staying inside.

Therefore, the hose 18 for taking out the fluid is again fed out from the hose reel 17, the hose 18 is drawn out to the place where the fluid storage tank 20 is installed, and the fluid A which solidifies at room temperature such as lard is stored in the storage tank 20. Even when the hose 18 is in a gentle heat-retaining state because the hose 18 is pulled out by a long distance or the hose 18 takes a long time to pull out the hose 18 when it is fed, and the hose 18 is cooled considerably by the outside cold air. Since the fluid A does not stay inside, the fluid A naturally does not cause clogging, and the heated fluid in the tank is smoothly fed to the storage tank through the hose by its feeding pressure. It will be.

Further, since the fluid A does not remain or remains only slightly inside the fluid take-out pipe 7 and the hose 18 integral with the pipe 7, the pipe 7 and the hose 18 are heated. The pipe 7 or hose 18 will naturally not be clogged even if the degree of graduation is moderate, so it is more economical than the case where the fluid A (oil and fat) is always retained in the pipe 7 or hose 18 It is possible to prevent the blockage due to the fluid.

By inserting air through the fluid take-out pipe 7 and the hose 18, it is easy for air to mix with the fluid in the pipe, which may deteriorate the accuracy of the flow meter for measuring the flow rate of the fluid. In the present invention, since the deaeration valve 10 is provided in the middle of the pipe, if air is mixed in the fluid flowing through the pipe, the air is removed by the deaeration valve 10 during the flow, and the bypass pipe is used. 16
Since it is designed to be discharged to the pipe 7 on the downstream side of the flow meter 12 through the flow path, it is possible to prevent deterioration of the accuracy of the flow meter as much as possible.

In the above embodiment, only the hose reel 17 is hermetically sealed by the heat insulating cover 22, but as shown in FIG.
In addition to the hose reel 17, the heat insulating cover 22 may seal the fluid take-out pipe 7, the branch pipe 7a, and the fluid take-out mechanism B.

According to this structure, since the fluid take-out pipe 7, the branch pipe 7a, and the fluid take-out mechanism B are heated by the warm air discharged from the warm air blower 23, the expensive jacket 28 covered by them is used. The mechanism for supplying steam to the jacket 28 can be omitted, and the structure can be simplified and the manufacturing cost can be reduced.

[0037]

According to the first aspect of the present invention, the fluid in the tank can be directly taken out through the fluid take-out pipe for the large-scale customers as before, but also for the small-scale customers. , The fluid in the tank can be taken out through a hose, and in particular, since the hose is sealed in the heat insulation cover and heated by the warm air discharged from the warm air machine, it can be used under normal temperature such as lard. Then, even when the fluid to be solidified is taken out through the hose, there is no fear that the fluid is solidified and clogged in the hose, and the fluid can be reliably taken out.

In particular, according to the present invention, the residual liquid removal air inlet is connected to the fluid extraction pipe, and the air is introduced into the pipe through the residual liquid removal air inlet.
The air passes through the pipe and the hose and discharges the fluid accumulated in the pipe and the hose to the outside by the pressure of the air, and the fluid does not remain in the pipe and the hose.

Therefore, when the fluid take-out hose is again drawn out from the hose reel, the hose is drawn out to the fluid storage tank installed by the customer, and the fluid that solidifies at room temperature such as lard is fed to the storage tank. In addition, even if the hose is pulled out for a long time or it takes a long time to pull out the hose and the hose comes into contact with cold air and is cooled considerably and keeps a gentle heat, fluid remains in the hose. Since there is no clogging, naturally, the heated fluid in the tank is smoothly fed to the storage tank through the hose due to the feeding pressure.

Further, since the fluid does not remain in the fluid take-out pipe and the hose integrated with the pipe, or only slightly remains therein, even if the pipe and the hose are gently heated. As a matter of course, the pipes and hoses do not become clogged, so it is possible to economically prevent the clogging of the pipes and hoses with fluid compared to the case where the fluid is always retained in the pipes and hoses. .

By inserting air through the fluid extraction pipe and the hose, air is likely to be mixed with the fluid in the pipe, and the accuracy of the flow meter for measuring the flow rate of the fluid may deteriorate. In the device, the degassing valve is interposed in the middle of the piping, so if air is mixed in the fluid flowing through the piping, the air will be removed by the degassing valve during the flow, and the accuracy of the flow meter will deteriorate. Can be prevented as much as possible.

According to the second aspect of the present invention, the deaeration valve interposed in the fluid take-out pipe has a bypass pipe in the fluid take-out pipe further downstream than the flow meter provided in the fluid take-out pipe downstream thereof. The air mixed in the fluid in the pipe is discharged to the pipe on the downstream side avoiding the flow meter, so that the accuracy of the flow meter is not deteriorated.
