Description

Method and a draining device for draining of a device provided with a bottom discharge
Background of the invention
The invention relates to a method according to the preamble of Claim 1 for draining of a device provided with a bottom discharge.
The invention also relates to a draining device according to the preamble of Claim 10 for draining of a device provided with a bottom discharge.
The invention relates to the draining of devices that are provided with bottom discharges, such as hydrometallurgical reactors, tanks, such as thickening tanks and cooling towers; to be more precise, to the draining of devices provided with bottom discharges, through the bottom discharge. In this context, draining refers to discharging the contents of the device that are in a liquid form.
A problem with devices provided with bottom discharges is that, in use, deposits form on their bottoms, which can be hard and which prevent the draining of the devices through the bottom discharge, since the deposits block the bottom discharge. One way of removing these deposits presently used is that the deposits are removed manually by entering the device and removing the deposits from the inside. This is not safe.
US 5,558,140 presents a fluid container draining device for draining fluid from a fluid container, an oil filter, in a controlled manner. The fluid container draining device has a threaded screw with a sharpened tip and a channel communicating between an opening at a forward end of the screw and a rear region of the threaded screw. When the screw is turned it will penetrate the wall of the fluid container and enter the fluid containing cavity of the fluid container. The threaded screw has a ra- dially extending abutment surface to provide fluid tight sealing between the screw and the fluid container's walls to prevent fluid leakage. A fluid valve is positioned at the rear region of the screw to provide fluid flow control between the interior of the fluid container and outside the fluid container. The fluid valve is provided with a fitting for connection to a suction line to thereby permit fluid to be evacuated from the fluid con- tainer.
Short description of the invention
The object of the invention is to provide a method and a draining device for draining of a device provided with a bottom discharge to solve the problem presented above. The object of the invention is achieved by the method according to the independent claim 1 for draining of a device provided with a bottom discharge and by a draining device according to the independent claim 10 for draining of a device provided with a bottom discharge. Preferred embodiments of the invention are described in the dependent claims.
The invention is based on the fact that for draining of a device provided with a bottom discharge, a draining device separate from the device to be drained is used. In connection with using the draining device, the draining device can be adapted to the bottom discharge of the device that is to be drained. The draining device comprises a pipe member, which is to be brought through the bottom discharge of the device, so that the pipe member is located at least partly in the interior of the device to be drained. The draining device comprises a channel that has a first open end and a second open end. The draining device is designed so that when the pipe member is brought through the bottom discharge of the device, so that the pipe member is at least partly located in the interior of the device to be drained, the first open end of the channel simultaneously settles in the interior of the device to be drained, while the second open end of the channel settles outside the device to be drained. In this way, the contents of the device to be drained can be drained out by means of the draining device through the channel of the draining device. In a solution according to the invention, the draining device comprises a flange member that comprises an opening provided with female threads. In this preferred embodiment, the female threads of the flange member are adapted to cooperate with the male threads provided on the pipe member, so that the location of the flange member on the pipe member can be changed by turning the flange member that is adapted to the pipe member. In this preferred embodiment, the flange member further comprises fastening members for fastening the flange member to the bottom discharge of the device to be drained so that, after fastening the flange member, the pipe member can be brought from outside the device to be drained through the bottom discharge at least partly into the interior of the device to be drained by turning or screwing the pipe member with respect to the flange member that is attached to the bottom discharge of the device to be drained. In this preferred embodiment, the pipe member can thus "bore" through the possible deposit that is. in the device to be drained next to the bottom discharge. One advantage provided by this solution is that the female threads of the flange member together with the male threads of the pipe member ensure that the pipe member is brought into the device, which is to be drained, directly and in a controlled manner. Another advantage achieved by this solution is that the female threads of the flange member together with the male threads of the pipe member keep the pipe member in place with respect to the device to be drained; to be more precise, in place in the bottom discharge of the device to be drained. The boring of the pipe member through the possible deposit next to the bottom discharge in the device to be drained is further enhanced, if the pipe member is provided with a sharp point at the end, which is taken first into the interior of the device to be drained. As the draining device is a separate device from the device to be drained and not intended to be installed in the device to be drained until in connection with the draining stage, one and the same draining device can be used in connection with many devices to be drained.

Detailed description of the invention
The invention relates to a method and to a draining device for draining a device 2 provided with a bottom discharge 1. Figs. 1, 3^4, 6-9 and 1 1-14 show only part of the device 2 provided with the bottom discharge 1. In the said figures, the bottom discharge 1 also comprises a valve 3 and a flange 4. The flange 4 can comprise a fastening means, such as holes, for detachably attaching the draining device 5 to the flange and, at the same time, to the bottom discharge 1 of the device 2 to be drained.
First, the method and some preferred embodiments thereof are described in de- tail.
In the method for draining a device 2 provided with a bottom discharge 1 , a draining device 5 separate from the device 2 to be drained is used, which in connection with using the draining device 5 can be adapted to the bottom discharge of the device to be drained, as shown in the figures in an exemplary manner. The draining device 5 comprises a pipe member 6, which is intended to be brought from outside the device 2 to be drained through the bottom discharge 1, so that the pipe member 6 is partly located in the interior 7 of the device 2.
The draining device 5 comprises a channel 8, which has a first open end 9 which, when the pipe member 6 is brought from outside the device 2 to be drained through the bottom discharge 1 , so that the pipe member 6 is partly located in the interior 7 of the device 2 to be drained, is adapted to be situated in the interior 7 of the device 2 to be drained and to be in contact with the interior 7 of the device 2 to be drained. The channel 8 also has a second open end 10 which, when the pipe member 6 is brought from outside the device 2 to be drained through the bottom discharge 1 , so that the pipe member 6 is partly located in the interior 7 of the device 2 to be drained, is adapted to be situated outside the device 2 to be drained.
The channel 8 can be fully formed in the pipe member 6 or, alternatively, partly in the pipe member 6 and partly, e.g., in a tube (not shown), which is connected to the pipe member 6.
The method comprises a stage, wherein the pipe member 6 of the draining device 5 is brought from outside the device 2 to be drained through the bottom discharge 1 , so that the pipe member 6 of the draining device 5 is partly located in the interior 7 of the device 2 to be drained, and so that the first open end 9 of the channel 8 of the draining device 5 is located in the interior 7 of the device 2 to be drained and is in contact with the interior 7 of the device 2 to be drained for draining the interior 7 of the device 2, which is provided with the bottom discharge 1, at least partly through the channel 8 of the draining device 5, e.g., for removing the liquid contents of the device 2, which is provided with the bottom discharge 1, at least partly through the channel 8 of the draining device 5.
The draining device 5 is provided with a valve member 11 between the first open end 9 of the channel 8 and the second open end 10 of the channel 8, so that the contact between the first open end 9 of the channel 8 and the second open end 10 of the channel 8 can be opened and closed. The first embodiment shown in Figs. 2-4 and the third embodiment shown in Figs. 10-14 comprise such a valve member 11 between the first open end 9 of the channel 8 and the second open end 10 of the channel 8. In that case, the method comprises a stage, wherein the valve member 1 1 of the draining device 5 is opened to open a contact between the first open end 9 of the channel 8 and the second open end 10 of the channel 8 for draining the interior 7 of the device 2 provided with the bottom discharge 1 at least partly through the channel 8 of the draining device 5, e.g., for removing the liquid contents (not shown) of the device 2 provided with the bottom discharge 1 through the channel 8 of the draining de- vice 5. The valve member 1 1 of the draining device 5 is preferably but not necessarily not opened until the pipe member 6 is at least partly brought into the interior 7 of the device 2 to be drained.
In the method, the pipe member 6 is preferably but not necessarily dimen- sioned with respect to the bottom discharge 1 so that the dimensions and the shape of the cross section of the pipe member 6 essentially correspond to those of the cross section of the opening of the bottom discharge 1. For example, it is possible that the bottom discharge 1 constitutes a pipe-like structure (not marked with a reference number) and that the pipe member 6 is dimensioned and shaped so that the outer di- mension and form of the cross section of the pipe member 6 essentially correspond to the inner dimension and form of the cross section of the pipe-like structure of the bottom discharge 1.
In a preferred embodiment of the method according to the invention, the draining device 5 is provided with a seal member 12 and the seal member 12 is attached to the bottom discharge 1 of the device 2 to be drained before the pipe member 6 of the draining device 5 is brought from outside the device 2 to be drained through the bottom discharge 1.
In a preferred embodiment of the method according to the invention, the draining device 5 is provided with a flange member 13 that comprises an opening 14, as is the case in the first preferred embodiment shown in Figs. 2—4. The flange member 13 is movably adapted to the pipe member 6, so that the pipe member 6 runs through the opening 14 of the flange member 13, i.e., so that the pipe member 6 penetrates through the opening 14. In the embodiment shown in Figs. 2—4, the seal member 12 is attached to the flange member 13 and the draining device 5, so that the flange member 13 is able to move with respect to the pipe member 6. In Fig. 3, the flange member 13 is attached to the flange 4 that belongs to the bottom discharge 1 of the device 2 to be drained for attaching the seal member 12 to the bottom discharge 1 of the device 2 to be drained, before the pipe member 6 in Fig. 4 is brought into the interior 7 of the device 2 to be drained through the bottom discharge 1 of the device 2 to be drained, so that the pipe member 6 of the draining device 5 is partly located in the interior 7 of the device 2 to be drained, and so that the first open end 9 of the channel 8 of the draining device 5 is located in the interior 7 of the device 2 to be drained and is in contact with the interior 7 of the device 2 to be drained. In this preferred embodiment, the flange member 13 is preferably but not necessarily detachably attached to the bottom dis- charge 1 of the device 2 to be drained by bolts or similar fastening members (not shown). In the figures, the flange member 13 is detachably attached by bolts to the flange 4 that belongs to the bottom discharge 1 of the device 2 to be drained. In the first embodiment shown in Figs. 2-4, a winching device 18 is used to hoist the draining device 5 upwards with respect to the device 2 to be drained, so that the pipe member 6 at least partly enters the interior 7 of the device 2 to be drained.
In a preferred embodiment of the method according to the invention, such as the second preferred embodiment shown in Figs. 5-9 and the third preferred embodiment shown in Figs. 10-14, the draining device 5 is provided with a flange member 13 that comprises an opening 14 provided with female threads 15. In this preferred embodiment, the pipe member 6 is provided with male threads 16, respectively, which cooperate with the female threads 15 of the opening 14 of the flange member 13. In this preferred embodiment, the flange member 13 is movably adapted to the pipe member 6, so that the pipe member 6 runs through the opening 14 of the flange member 13, i.e., so that the pipe member 6 penetrates through the opening 14. In this preferred embodiment, the flange member 13 is attached to the bottom discharge 1 of the device 2 to be drained, before the pipe member 6 is brought into the interior 7 of the device 2 to be drained, by rotating or "screwing" the pipe member 6 through the bottom discharge 1 of the device 2 to be drained, so that the first open end 9 of the channel 8 of the draining device 5 is located in the interior 7 of the device 2 to be drained and is in contact with the interior 7 of the device 2 to be drained. The flange member 13 is preferably but not necessarily detachably attached to the bottom discharge 1. For example, it is possible that the flange member 13 is attached to the bottom discharge 1 by bolts or similar fastening members (not shown), hi the figures, the flange member 13 is detachably attached by bolts to the flange 4 that belongs to the bottom discharge 1 of the device 2 to be drained. In the second and third preferred embodiments shown in Figs. 5-14, the seal member 12 is attached to the flange member and the draining device 5, so that the flange member is able to move, i.e., rotate with respect to the pipe member 6. In the second and third preferred embodiments shown in Figs. 5-14, the draining device 5 comprises cranks 20 for turning the pipe member 6 with respect to the flange member 13 attached to the bottom discharge 1, so that the pipe member 6 at least partly enters the interior 7 of the device 2 to be drained. Figs. 6-9 show part of the operating principle of the second preferred embodiment of the method according to the invention.

In Fig. 9, the pipe member 6 penetrates the deposit 17 on the bottom of the interior 7 of the device 2 to be drained, after which the contents of the device 2 to be drained can be drained out through the channel 8 of the draining device 5. The pipe member 6 is preferably but not necessarily provided with a sharp point 19, and the method then comprises a stage, wherein the pipe member 6, with the sharp point 19 ahead, is brought into the interior 7 of the device 2 to be drained through the bottom discharge 1 of the device 2 to be drained. In the embodiments shown in the figures, the pipe member 6 is provided with triangular pieces (not marked with reference numbers), which have sharp edges and which constitute the sharp point 19 of the pipe member 6. It is also possible that the sharp point 19 comprises a saw-shaped structure, the purpose of which is to bore a way through the deposit 17 that lies on the bottom of the interior 7 of the device 2 to be drained. The method preferably but not necessarily comprises a stage, wherein an agent that softens the deposit 17 is fed through the draining device 5 into the interior 7 of the device 2 to be drained. The second preferred embodiment shown in Figs. 5-9 comprises a feeding means 19 for feeding the agent (not shown) that softens the deposit 17 into the interior 7 of the device 2 to be drained through the draining device 5. In the embodiments shown in the figures, the device 2 having the bottom discharge 1 comprising the valve 3 is drained, whereby the valve 3 is first opened and, thereafter, the pipe member 6 is brought through the opened valve 3.

For example, it is possible that a tube (not shown) is attached to the pipe member 6, so that the channel 8 comprises a portion in the pipe member 6 and a portion in the tube. The channel 8 has a first open end 9 which, when the pipe member 6 is brought from outside the device 2 to be drained through the bottom discharge 1 , so that the pipe member 6 is partly located in the interior 7 of the device 2 to be drained, is adapted to be situated in the interior 7 of the device 2 to be drained and to be in contact with the interior 7 of the device 2 to be drained. The channel 8 has a second open end 10 which, when the pipe member 6 is brought from outside the device 2 to be drained through the bottom discharge 1 , so that the pipe member 6 is partly located in the interior 7 of the device 2 to be drained, is adapted to be situated outside the device 2 to be drained. The draining device 5 comprises a valve member 11 between the first open end 9 and the second open end 10 of the channel 8, so that the contact between the first open end 9 of the channel 8 and the second open 10 end of the channel 8 can be opened and closed. The pipe member 6 is preferably but not necessarily dimensioned so that the dimensions and the shape of the cross section of the pipe member 6 essentially correspond to those of the cross section of the opening 14 of the bottom discharge 1 of the device 2 to be drained. For example, it is possible that the bottom discharge 1 constitutes a pipe-like structure (not marked with a reference number) and that the pipe member 6 is dimensioned and shaped so that the outer dimension and form of the cross section of the pipe member 6 essentially correspond to the inner dimension and form of the cross section of the pipe-like structure of the bottom discharge 1.
