Description

Cleaning device of extraction gun

Technical Field

The utility model relates to the production and transportation of fluid materials in the industries of petrochemical industry, food and the like. More specifically, the present invention relates to an extraction system for pumping fluid material, and in particular to a cleaning technique for an extraction gun in an extraction system.

Background

In the petrochemical, food and other industries, extraction systems are often used to pump fluid materials. For example, the blending production of lubricating oils requires the addition of different types of additives to the base oil to formulate lubricating oils adapted to the lubricating requirements of different equipment and vehicles, for which it is known to use extraction systems to extract the required additives. Such extraction systems may typically include an extraction lance connected to an extraction pump to draw the additive from the additive drum upon actuation of the extraction pump, and then deliver the additive, for example, via an extraction line to a blending tank containing the base oil.

Since extraction systems are relatively expensive, it is common today to perform the extraction of different materials with one extraction system, for example, after extracting a predetermined amount of a first additive with an extraction gun, and then still extracting a second additive with the same extraction gun. However, when the extracted material is to be changed, if the extraction lance is not handled, the extracted material will remain in the extraction lance, which on the one hand results in a waste of raw material and on the other hand results in different materials being mixed in an undesired manner and thus in cross-contamination. It is known in the art to use a base stock, such as base oil, to clean the extraction lance, which requires the formation of a circulating flushing system including the extraction lance cleaning drum and the base stock tank, which may cause a greater degree of contamination.

Thus, avoiding waste of material and avoiding cross-contamination between different materials is a major problem to be solved in the use of extraction systems.

Detailed Description

Embodiments of the present invention are described below with reference to the drawings. In the following description, numerous specific details are set forth in order to provide a more thorough understanding and enabling description of the present invention to those skilled in the art. It should be understood, however, that the intention is not to limit the invention to the particular embodiments described. Rather, the invention can be implemented with any combination of the various features and elements described below, whether or not they relate to different exemplary embodiments. Thus, the following aspects, features, embodiments and advantages are merely illustrative and should not be construed as limiting the scope of the invention.

The cleaning device of the utility model can be especially used for cleaning the extraction gun of the extraction system. As is generally known, such extraction guns have a cylindrical or hollow cylindrical shank, whereby an internal passage can be defined inside the shank. In use, the lance can be extended into a container containing the material to be extracted and the material in the container is sucked out through its internal passage or into the target container by means of the suction force of an extraction pump connected thereto. The material is in particular a fluid material, for example a liquid material. After the material in one container has been pumped out or a predetermined amount of material has been pumped out of one container, the extraction gun may be moved to another container in order to continue pumping the same material or to pump other kinds of material. In this process, it is possible to use the cleaning device of the invention to clean the extraction gun, in particular when the kind of material to be pumped changes, and then to place the extraction gun in the further container in order to continue the extraction operation.

Referring to fig. 1, the cleaning device of the present invention comprises an independent gun washing barrel 1 and a gun washing loop 2 connected to the gun washing barrel 1, wherein the gun washing barrel 1 is located in the gun washing loop 2. Preferably, the lance circuit 2 may be constituted by a line dedicated to the lance barrel 1, however, the lance circuit 2 may also comprise known lines, for example comprising an extraction line connected to an extraction lance to be cleaned.

As shown in fig. 1, the gun barrel 1 may comprise a barrel 11, said barrel 11 defining an inner cavity for receiving the lance of the extraction gun. The cleaning operation of the lance of the extraction lance is mainly carried out in this inner chamber. Preferably, the gun barrel 1 may further comprise a head 12 attached to a top end of the barrel 11, the head 12 may define an inlet opening in communication with the interior cavity of the barrel 11.

The inner cavity of the cylinder 11 may have a form that matches the lance of an extraction gun, both to allow the lance to be inserted into the inner cavity unimpeded and to allow the inner cavity to form an enclosed space after insertion of the lance. For this purpose, the inner cavity preferably has a shape that conforms to the outer contour of the gun shaft, in particular a cylindrical shape, and preferably has a length and a diameter that are larger than the length and the outer diameter of the gun shaft. In particular, the length and diameter of the lumen may be slightly greater than the length and outer diameter of the lance or may be only greater than the length and outer diameter of the lance by a predetermined range. Therefore, the volume of the gun washing barrel 1 can be reduced as much as possible, so that the material waste can be reduced, and the space occupied by the cleaning device can be reduced.

Advantageously, the inner cavity of the cylinder 11 can be hermetically closed while receiving the lance of the extraction gun. Thereby, the cleaning operation of the extraction gun can be performed in the closed operation space. In this way, on the one hand, it is possible to avoid pollution of the surrounding environment by splashing or spillage of the fluid that may occur during the cleaning operation, and on the other hand it is possible to ensure an effective and comprehensive recovery of the cleaning fluid and of the residual material removed from the extraction lance. Furthermore, the closed operating space ensures a thorough cleaning of the extraction lance.

Still referring to fig. 1, the gun wash circuit 2 may include a first circuit portion 21 and a second circuit portion 22. Said first circuit portion 21 is intended to supply cleaning fluid into the barrel 11 of the gun barrel 1, in particular into the internal cavity of this barrel 11. To this end, the first circuit portion 21 can be connected on the one hand via the first suction pump 3 to the rinsing fluid reservoir 4 and on the other hand communicate with a supply port on the cylinder 11. The cleaning fluid is used to clean the extraction gun and may be a common or shared fluid used in the production process. For example, in the blending production of lubricating oils, the washing fluid may be a base oil, and the washing fluid storage container 4 may be formed by a dedicated base oil tank. Of course, the cleaning fluid may also be a dedicated cleaning fluid, e.g. a dedicated cleaning agent, or may even be pressurized air.

The second circuit portion 22 is intended to draw cleaning fluid from the barrel 11 of the gun barrel 1. In particular, the second circuit portion 22 is arranged to suck a washing fluid, in particular a washing fluid that has been subjected to a washing operation, i.e. a mixture of washing fluid and residual material in the extraction gun, via an internal channel of a lance rod (not shown) of the extraction gun inserted in the barrel 11. For this purpose, the second circuit portion 22 may extend outward from the inlet opening of the barrel 11, and may be connected to the second suction pump 5. Preferably, the second circuit portion 22 may be formed by an existing extraction line connected to the extraction lance to be cleaned, and the second suction pump 5 may be formed by an existing extraction pump connected to the extraction lance to be cleaned. The fluid (mixture of cleaning fluid and residual material) drawn through the second circuit portion 22 may be sent to a dedicated collection vessel. Preferably, however, the fluid drawn through the second loop portion 22 may be sent to a vessel used in the production process. For example, in a lubricating oil blending production application, the extracted fluid can be fed into a blending kettle, so that residual materials cleaned from an extraction gun can be fully utilized, and the waste of the materials is further reduced.

The gun circuit 2 is thus constructed as a circuit in which the washing fluid flows in one direction (indicated by arrow F1 in fig. 1), and the inner cavity of the barrel 11 of the gun barrel 1 and the inner channel of the extraction gun shaft to be cleaned also form part of the gun circuit 2. Thereby realizing the full cleaning of the inner wall and the outer wall of the extraction gun lance.

When the lance of the extraction gun has been inserted into the lance barrel 1 so that a cleaning operation can be performed, the first suction pump 3 is activated to supply cleaning fluid into the barrel 11 of said lance barrel 1 via the first circuit portion 21, and the second suction pump 5 is activated (in case the second circuit portion 22 has been in communication with the internal passage of the extraction gun lance) to withdraw cleaning fluid from said barrel 11. In the process, the cleaning fluid flows in the inner cavity of the cylinder 11 along the outer wall of the extraction lance shank due to pressure and/or suction, then enters the inner channel of the extraction lance shank and flows along the inner wall of the same, finally leaves the lance barrel 1 via the second circuit part 22 connected to said shank and is further conveyed to a dedicated collection vessel or production vessel, such as a tempering kettle, whereby a flush cleaning of the outer and inner walls of the extraction lance shank is achieved. When a predetermined amount of the washing fluid has been sucked by the first suction pump 3, the first and second suction pumps 3, 5 may be turned off to end the washing operation.

Preferably, the second suction pump 5 is started earlier than the first suction pump 3 at the start of the cleaning operation, whereby it is possible to avoid that the pressure (e.g. vacuum pressure or cleaning fluid pressure) in the gun barrel 1 damages the first suction pump 3. At the end of the cleaning operation, the second suction pump 5 is switched off later than the first suction pump 3, so that the used cleaning fluid in the gun barrel 1 can be evacuated as far as possible.

In addition, it should be noted that the predetermined amount of cleaning fluid described above may be determined by the user as desired. The predetermined amount may be determined, for example, by taking into account the type of material remaining in the extraction gun to be cleaned (in particular its viscosity, etc.), the desired cleanliness of the extraction gun, etc.

The utility model discloses a belt cleaning device has formed a closed belt cleaning device from this, wherein washes the rifle return circuit and has formed a confined washing fluid flow loop to the washing to the barral of a gun of extraction rifle is gone on in inclosed environment, has both guaranteed the abundant washing to the extraction rifle, has avoided the influence or the pollution to the surrounding environment again.

In particular, the gun barrel 1 may be arranged substantially vertically, so as to facilitate, on the one hand, the insertion of the lance of the extraction gun from the upper end of the gun barrel 1, and, on the other hand, the outflow of used cleaning fluid, in particular cleaning fluid remaining after suction through the second circuit portion 22, from the lower end of the gun barrel 1 by gravity (as indicated by the hollow arrow F2 in fig. 1).

According to the embodiment shown in fig. 1, the barrel 11 of the gun barrel 1 may include a body portion 111 for forming the internal cavity described above. The main body portion 111 may be straight and may be made of seamless tubing, such as seamless steel tubing. The dimensions of the main body part 111, in particular the radial dimension (diameter) and the axial dimension (length), can be matched to the corresponding dimensions of the lance of the extraction lance to be cleaned.

Advantageously, the supply port for connection to the first circuit portion 21 of the gun washing circuit 2 may be formed in the main body portion 111, in particular in a portion of the main body portion 111 near the top end. This positioning of the supply port is advantageous to ensure that a sufficient amount of cleaning fluid is delivered into the interior cavity of the barrel 11 and to facilitate adequate flushing of the exterior wall of the lance of the extraction gun by the flow of cleaning fluid.

It is also advantageous when the cleaning fluid is a liquid to provide a vent (not shown) in the circumferential wall of the barrel 11 for venting gases that may be entrained in the cleaning fluid and to avoid the formation of a detrimental vacuum in the interior cavity of the barrel 11. Preferably, the exhaust port may be arranged above the supply port, in other words, closer to the top end of the barrel 11 than the supply port.

Still referring to fig. 1, in the illustrated embodiment, barrel 11 of gun barrel 1 may further include a transition portion 112 disposed at a top end of main portion 111 and/or a buffer portion 113 disposed at a bottom end of main portion 111.

The transition portion 112 may be used to connect the head 12 and may have an outer diameter that is smaller than the outer diameter of the body portion 111. The provision of the transition portion 112 ensures, on the one hand, that the tightness of the body portion 111 is not impaired, and, on the other hand, can be designed separately in order to facilitate the connection, for example a detachable connection, of the head 12 to the cartridge 11.

In the embodiment shown in fig. 1, the buffer portion 113 may be a curved portion formed of an arc-shaped pipe segment and may have the same radial dimensions (inner and outer diameters) as the body portion 111. Advantageously, the end portion of the curved buffer portion 113 (i.e. the bottom end portion of the barrel 11) may extend in a direction substantially perpendicular to the main body portion 111 (i.e. in a horizontal direction when the barrel 11 of the gun barrel 1 is vertically disposed as shown in fig. 1), so that its connection and positioning with the subsequent related devices may be facilitated. Also advantageously, the end portion of said buffer portion 113 may be provided with a bottom valve 114, for example a shut-off valve commonly used for pipes. The foot valve 114 may be closed during the cleaning operation to form a closed space in the interior of the bowl 11 and may be opened after the cleaning operation is completed to discharge the used cleaning fluid residue.

As an alternative to an arc-shaped pipe section, the buffer portion 113 may also be formed by a straight pipe section. Advantageously, the radial dimensions (inner and outer diameter) of the straight tube section are smaller than the radial dimensions of the body portion 111, and the axial length of the straight tube section is much smaller than the axial length of the body portion 111. Thereby, the straight tube section may define a buffer volume which may be used for receiving a possible excess of washing fluid and/or for receiving a residue of used washing fluid. The remainder of the cleaning fluid can be discharged from the gun barrel by opening the foot valve provided at the end of the buffer portion (in this case a straight pipe section) as described above.

Here, it should be noted that the main body portion 111, the transition portion 112, and the buffer portion 113 of the barrel 11 may be made of the same material and may be integrally formed.

Referring now to fig. 2, therein is shown a cross-sectional view of the head 12 of the gun barrel 1. The head 12 may be connected to the top end of the barrel 11, i.e. to the transition portion 112 of the barrel 11, for example by welding. Of course, the head 12 may also be removably connected to the barrel 11 by other means, such as by threads.

As can be seen in fig. 2, head 12 may have an outer diameter that is greater than the outer diameter of barrel 11 and may define an inlet opening 121 that communicates with the interior cavity of barrel 11. The diameter of the inlet opening 121 is significantly larger than the diameter of the inner cavity of the barrel 11 and may advantageously have a tapered or conical or frustoconical shape in order to facilitate the alignment and insertion of the extraction gun lance.

The head 12 may also define, internally, a rectilinear transition passage 122 contiguous with the inlet opening 121, the transition passage 122 having a diameter substantially the same as the diameter of the internal cavity of the barrel 11. Preferably, a sealing ring 13 may be provided in the transition passage 122. The sealing ring 13 can abut against the outer wall of the extraction lance when said lance is inserted into the lance barrel 1, thereby sealing the inner cavity of the barrel 11. For example, the seal ring 13 may be a shaft lip seal, and may be made of a material such as a fluororubber. It is also preferred that a sheath can be provided in said transition passage 122, which sheath can be placed, for example, above the sealing ring 13 and can have an inner diameter matching the lance of the extraction gun for protecting and guiding said lance during insertion of the latter into the gun barrel 1, while reducing wear on the inner wall of the head 12.

Still referring to fig. 2, the end portion of the head 12 may have a flange 123 extending in a radial direction to facilitate handling of the entire barrel 1, such as shipping, positioning and attachment to a rack. In addition, a stepped hole may be formed inside the flange 123.

The utility model discloses a belt cleaning device can produce following favorable technological effect:

1) Provides a real possibility for thorough cleaning or emptying of the extraction system;

2) The design of the small-volume gun washing barrel reduces the waste of materials and the occupied space;

3) The gun washing operation is carried out in a closed space, so that the surrounding environment is not influenced or polluted;

4) The cleaning device can form a closed loop system, and the cleaning device can circularly clean the gun without polluting other materials.

In conclusion, the cleaning device of the present invention minimizes the cross-contamination that may occur in known extraction systems. The cleaning device can utilize the least amount of cleaning fluid to flush the loop of the extraction gun through the circulating cleaning function, so that the residual quantity of materials in the loop reaches the lowest value.

It should be noted that the above-described embodiments should be regarded as merely exemplary, and the present invention is not limited to these embodiments. Upon consideration of the present specification, those skilled in the art can make various changes and modifications without departing from the scope or spirit of the present invention.
