Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an oil flushing device, and more particularly to a small and lightweight oil flushing device.

(Prior Art) In order to purify hydraulic oil used in machine tools, etc., a large oil flushing device such as that disclosed in Japanese Patent Laid-Open No. 61-82877 has been used, and this is mounted on a trolley. Then, the portable thing was carried into the factory, and the end of the circulation hose communicating with the device was connected to the hose of the hydraulic device.

However, in recent factories, etc., the layout is such that hydraulic systems are collectively installed in an underground pit or in an open space located at a high place. Not only has it become difficult to easily carry the flushing device near the hydraulic device, but there is also the problem that the work of connecting and disconnecting the hose cannot be performed easily because of the installation space.

(Problems to be solved by the invention) The present invention has been made in view of such circumstances, and the purpose thereof is to be able to directly connect to an oil tank and to easily carry it to a narrow place with one hand. An object is to provide a small and lightweight oil flushing device that can be used.

(Means for Solving the Problems) That is, the present invention is an oil flushing device for achieving the above problems, in which an inner and outer double pipe connection portion is provided at the lower end of the device main body with a handgrip on the upper side. The fixed side pipe of the two suction pipes which are slidably coupled in the axial direction is connected to the pipe connection part, and the bottomed discharge pipe having a discharge port on the lower end peripheral surface is formed on the outer pipe connection part. Each of them is fixed downward and the sliding side pipe of the suction pipe is projected downward from the bottom plate of the discharge pipe. The flow path is communicated with the discharge pipe from the suction pipe through the pump and the oil element.

(Operation) With the configuration as described above, the sliding side suction pipe is adjusted up and down to suck the dirty oil at the bottom of the oil tank, and at the same time, the purified oil is horizontally moved above the oil tank. The oil is discharged radially, and the purification process of the treated oil is suppressed as much as possible, and the purification process is effectively performed.

(Example) Then, the Example illustrated below is described.

The apparatus main body shown by the reference numeral 1 in the drawing is configured so that it can be carried with one hand by a grip 3 attached to the upper end of the apparatus via a bracket 2. The apparatus main body 1 is provided with inner and outer double pipe connection portions 4 and 5 at its lower end, and a fixed side suction pipe 7 is attached to the inner pipe connection portion 4 in a downward and airtight manner, and also outside. A bottomed discharge pipe 10 having a plurality of discharge ports 11 on its lower end peripheral surface is airtightly fixed so as to cover the suction pipe 7, and further, the fixed side suction pipe 7 described above. Has
A sliding side suction pipe 9 having a flange 8 at its upper end is slidably mounted so as to penetrate the bottom plate 12 of the discharge pipe 10 and project downward.

On the other hand, below the apparatus body 1, an air motor 14 is attached to one surface thereof, and a pump 17 connected to a motor shaft 15 through a joint 16 is attached to the other surface thereof in a distributed manner. Oil elements 18 and 18 are removably attached, respectively.

An oil passage 22 is also provided inside the apparatus main body 1, and a passage on the suction side communicating with the pipe connecting portion 4 on the inside is provided.
22a is connected to each inflow port 19 of the oil elements 18, 18 via the pump 17 and the relief valve 23, and is connected to each outflow side 20 of the oil elements 18, 18 on the discharge side passage 22b.
Is connected to the outer pipe connecting portion 5 via the outside of the suction side passage 22a.

In the figure, reference numeral 24 is a hose joint connected to the air motor 14, 25 is a silencer, and 26 is a display lamp for notifying the replacement time of the oil element 18.

In the above-mentioned embodiment, the lower end is 10 in advance from the bottom of the oil tank 30.
The sliding side suction pipe 9 is expanded and contracted so as to be located at a position of cm and the length thereof is adjusted, and then inserted into the supply port 31 of the oil tank 30. Then, when the motor 14 is operated in this state, the oil at the bottom of the oil tank 30 is sucked by the pump 17, passes through the expansion pipe 9, the suction pipe 7 and the suction side flow passage 22a inside the main body 1 and enters the oil elements 18, 18. After entering, the impurities are removed here by the filter paper, the filter net 19 and the like inside, and then discharged to the discharge pipe 10 from the outlet through the outflow side flow path 22b inside the main body 1.

By the way, since the discharge pipe 10 is provided with several discharge ports 11 ... on its lower end peripheral surface, the oil discharged into the discharge pipe 10 through the purification treatment is horizontally oriented in the upper part of the oil tank 30. The oil in the oil tank 30 is efficiently purified while being radially released and restraining suction on the suction side again as much as possible.

5 and 6 show three oil elements 18a, 18
b, 18c are connected in series, and filtration meshes 21a, 21b, 21c, in which meshes are sequentially fined, for example, 50μ, 20μ, 6μ from the suction side, are provided on these to purify dirty oil in stages. With this configuration, two oil elements 18a and 18b are provided on both sides of the apparatus body 1, and
By mounting the remaining oil element 18c horizontally on the top of the main body 1 with a space,
The function of c is added to c.

(Effect) As described above, according to the present invention, since the grip is provided on the upper part of the apparatus body, it can be carried with one hand and used in a narrow place. Moreover, at the lower end of the device body,
Since two slidable suction pipes and a bottomed discharge pipe having a discharge port on the lower end peripheral surface are provided, the suction pipe on the sliding side is projected downward from the bottom plate of the discharge pipe. By adjusting the sliding side suction pipe up and down, it is possible to suck the dirty oil at the bottom of the oil tank, and at the same time, the purified oil is discharged horizontally in the horizontal direction above the oil tank to re-process the oil. The purification process can be suppressed as much as possible, and this effective process can sufficiently compensate for the weakness of the purification power due to the downsizing of the device.
