Description

Technical Field

[0001] The utility model relates to the field of natural gas production, in particular to a portable sand cleaning device. Background Art

[0002] When sand cleaning operation is carried out on the oil and gas pipeline network, clean water needs to be brought to the side of the separator, and the clean water is pumped into the separator through a water pump to wash the separator. The washed sand, sundries and sewage are discharged from below the separator. In order to prevent the sewage from spilling into the environment, the staff needs to lay an anti-seepage cloth below the separator and form a trough shape to collect the washed sewage. At the same time, since there is usually no water source around the separator, in order to save water, the collected sewage will be pumped back into the separator for secondary use after simple separation treatment.

[0003] The above-mentioned sand cleaning operation method has some deficiencies:

[0004] 1. The sewage collection device formed by temporarily laying the anti-seepage cloth cannot have a good gathering effect on the sewage. The sewage is easy to flow around on the anti-seepage cloth, causing pollution, and it is not convenient for the secondary use of the sewage.

[0005] 2. The anti-seepage cloth does not have the function of filtering sewage. A large amount of sediment may be carried into the separator during the process of pumping the sewage on the anti-seepage cloth. On the one hand, the sand cleaning effect of the separator is not ideal, and on the other hand, the sediment entering the water pump is easy to cause damage to the water pump.

[0006] Therefore, at present, a technical solution is needed to solve the technical problems that when the sewage is received by laying the anti-seepage cloth at the bottom of the separator, the sewage is easy to flow into the surrounding environment, and at the same time, it is difficult to separate the received sewage from the sediment, and the sand cleaning effect is not good when it is pumped back into the separator again, and it will also cause damage to the water pump. Summary of the Utility Model

[0007] The purpose of the utility model is to overcome the technical problems that when the sewage is received by laying the anti-seepage cloth at the bottom of the separator, the sewage is easy to flow into the surrounding environment, and at the same time, it is difficult to separate the received sewage from the sediment, and the sand cleaning effect is not good when it is pumped back into the separator again, and it will also cause damage to the water pump, and provide a portable sand cleaning device.

[0008] The utility model provides a portable sand cleaning device, which includes an airbag. The airbag is provided with an inflation port. After the airbag is inflated, a liquid accumulation tank is formed at the top. The airbag is connected with a filter screen, and the filter screen divides the liquid accumulation tank into two parts, namely a sundries chamber and a clean water chamber.

[0009] The utility model relates to a portable sand cleaning device. When in use, an airbag is placed at the bottom of a separator. Air is inflated into the airbag through an inflation port. After the airbag reaches a preset shape, the inflation port is closed by a sealing plug. Then, clear water is introduced into the separator to wash the sediment inside the separator. The sewage generated during the washing process flows into a liquid accumulation tank at the top of the airbag. In the liquid accumulation tank, the sewage first enters a debris chamber. Under the separation action of a filter screen, sediment and debris are blocked, and the clear water passes through the filter screen and flows into a clear water chamber. Then, the clear water in the clear water chamber is pumped into the separator by a water pump. By arranging an airbag that can form a liquid accumulation tank after inflation, it is convenient to load the sewage generated during the washing process of the separator. This not only improves the loading capacity of the sewage but also prevents the sewage from flowing into the surrounding environment. The filter screen arranged in the liquid accumulation tank can block sediment and impurities in the sewage, allowing the clear water to flow to the other side of the filter screen, facilitating the operator to extract the clear water for secondary use, reducing the failure rate of the water pump during the sand cleaning operation, and improving the cleaning efficiency of the separator.

[0010] Preferably, the airbag includes an inner wall and an outer wall, and a pulling member is connected between the inner wall and the outer wall.

[0011] By connecting a pulling member between the inner wall and the outer wall of the airbag, the inner wall and the outer wall are kept at a certain distance after inflation, so that the airbag can form a preset shape after inflation, ensuring that the shape of the airbag after inflation conforms to the use state.

[0012] Preferably, the pulling member includes a plurality of flexible ropes, and both ends of the flexible ropes are respectively connected to the inner wall and the outer wall.

[0013] Among them, the flexible ropes can be ropes made of flexible materials such as nylon and rubber. After connecting the inner wall and the outer wall through the flexible ropes, there is a pulling effect between the inner wall and the outer wall to ensure that the airbag can form a preset shape after inflation.

[0014] Preferably, the airbag forms a box body with an opening at the top after inflation.

[0015] The inner cavity of the box body is the liquid accumulation tank. The distance between the inner and outer walls of the box body is uniform, making the volume of the liquid accumulation tank larger, capable of holding more liquid. At the same time, on the premise of meeting the liquid accumulation, the space occupied by the entire airbag is smaller, facilitating the installation of the airbag in the narrow space under the separator.

[0016] Preferably, the airbag is a rubber material structural member.

[0017] The airbag made of rubber material has good elasticity and can quickly expand into an airbag structure after inflation. Moreover, the rubber material has good corrosion resistance. In natural gas production, the liquid in the separator contains certain acidic components, and the airbag made of rubber material can avoid the corrosion caused by these acidic components.

[0018] Preferably, the filter screen is detachably connected to the inner wall of the liquid accumulation tank.

[0019] The material of the filter screen is usually metal or other materials with relatively hard texture, which is not convenient to be stored together with the airbag. The detachable connection method between the filter screen and the airbag enables the filter screen and the airbag to be stored separately, which plays a role in protecting the airbag. At the same time, it is convenient to fold the airbag into a smaller size, facilitating carrying and storage.

[0020] Preferably, clamping grooves are respectively arranged on both sides of the inner wall of the liquid accumulation tank, and clamping blocks that are slidably matched with the clamping grooves are respectively arranged on both sides of the filter screen.

[0021] The filter screen is inserted into the clamping grooves on both sides of the inner wall of the liquid accumulation tank through the clamping blocks on its both sides, realizing the detachable connection between the filter screen and the airbag, and the disassembly and assembly are simple.

[0022] Preferably, an installation strip is connected to the inner side wall of the liquid accumulation tank. The installation strip is arranged along the height direction of the liquid accumulation tank, the clamping groove is arranged on the installation strip, and the clamping groove is arranged along the length direction of the installation strip.

[0023] In order to maintain lightness, the wall of the airbag is set to be relatively thin, so it is not convenient to directly set clamping grooves on the airbag wall. In this solution, by adding an installation strip to the inner wall of the airbag and then setting the clamping groove on the installation strip, the installation of the filter screen in the airbag is realized, and at the same time, the structure of the airbag will not be affected.

[0024] Preferably, a fixing strip is arranged on the inner bottom wall of the liquid accumulation tank. The fixing strip is provided with a sealing groove. The sealing groove is arranged along the length direction of the fixing strip. Both ends of the fixing strip are respectively connected to the two installation strips. A sealing block is connected to the bottom of the filter screen, and the sealing block is nested with the sealing groove.

[0025] By adding a fixing strip to the airbag, the sealing block at the bottom of the filter screen is nested with the sealing groove on the fixing strip, forming a seal at the bottom of the filter screen to prevent sediment from leaking into the clean water cavity through the gap between the bottom of the filter screen and the inner bottom wall of the airbag.

[0026] Preferably, several tie straps are connected to the airbag, and the several tie straps are arranged around the airbag.

[0027] The airbag can be fixed to the separator or to the pipelines and equipment around the separator through cable ties, so that the position of the airbag at the bottom of the separator is more stable and it is not easy to displace under the scouring action of sewage.

[0028] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0029] 1. By providing an airbag that can form a liquid accumulation tank after inflation, it is convenient to load the sewage generated during the flushing process of the separator, improving the sewage loading capacity;

[0030] 2. The liquid accumulation tank at the top of the airbag has a better effect of gathering sewage and can prevent the sewage from flowing into the surrounding environment;

[0031] 3. The filter screen arranged in the liquid accumulation tank can block the sediment and impurities in the sewage, enabling the clear water to flow to the other side of the filter screen, facilitating the operator to extract the clear water for secondary use and reducing the failure rate of the water pump during the sand cleaning operation;

[0032] 4. The filtered clear water is pumped back into the separator for sand cleaning operation, which can improve the sand cleaning efficiency of the separator and also make the separator cleaner. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Embodiment 1

[0048] As Figure 1 shown, a portable sand cleaning device includes an airbag 1. The airbag 1 is provided with an inflation port 101. After the airbag 1 is inflated, a liquid accumulation tank 102 is formed at the top. The airbag 1 is connected with a filter screen 2. The filter screen 2 divides the liquid accumulation tank 102 into two parts, namely a sundry chamber 1021 and a clear water chamber 1022.

[0049] During use, place the airbag 1 at the bottom of the separator. Inflate the airbag 1 through the inflation port 101. After the airbag 1 reaches the preset shape, close the inflation port 101 with a sealing plug. Introduce clear water into the separator to wash the sediment inside the separator. The sewage generated during the washing process flows into the liquid accumulation tank 102 at the top of the airbag 1. In the liquid accumulation tank 102, the sewage first enters the sundry chamber 1021. Under the separation effect of the filter screen 2, the sediment and sundries are blocked, and the clear water passes through the filter screen 2 and flows into the clear water chamber 1022. Then, pump the clear water in the clear water chamber 1022 into the separator. In this application, by setting the airbag 1 that can form the liquid accumulation tank 102 after inflation, it is convenient to load the sewage generated during the washing process of the separator, which not only improves the loading capacity of the sewage but also prevents the sewage from flowing into the surrounding environment. The filter screen 2 arranged in the liquid accumulation tank 102 can block the sediment and impurities in the sewage, making the clear water flow to the other side of the filter screen, facilitating the operator to extract the clear water for secondary use, reducing the failure rate of the water pump during the sand cleaning operation, and also improving the cleaning efficiency of the separator.

[0050] Airbag 1: It includes an inner wall 11 and an outer wall 12. A pulling member 3 is connected between the inner wall 11 and the outer wall 12. A pulling member 12 is connected between the inner wall 11 and the outer wall 11 of the airbag 1, so that the inner wall 11 and the outer wall 12 are kept at a certain distance after inflation, so that the airbag 1 can form a preset shape after inflation, ensuring that the shape of the airbag 1 after inflation conforms to the use state. Among them, the pulling member 3 includes a number of flexible ropes 31. Both ends of the flexible rope 31 are respectively connected to the inner wall 11 and the outer wall 12. The flexible rope 31 can be a rope made of flexible materials such as nylon and rubber. After connecting the inner wall 11 and the outer wall 12 through the flexible rope 31, there is a pulling effect between the inner wall 11 and the outer wall 12 to ensure that the airbag 1 can form a preset shape after inflation.

[0051] In one or several embodiments, the airbag 1 forms a box body with an opening at the top after inflation. The inner cavity of the box body is the liquid accumulation tank 102. The distance between the inner and outer walls of the box body is uniform, making the volume of the liquid accumulation tank 102 larger and capable of holding more liquid. At the same time, on the premise of meeting the liquid accumulation, the entire airbag 1 occupies less space, facilitating the installation of the airbag 1 in the narrow space under the separator.

[0052] In one or several embodiments, the airbag 1 is a rubber material structural member. The airbag 1 made of rubber material has good elasticity and can quickly expand into the airbag 1 structure after inflation. And the rubber material has good corrosion resistance. In natural gas production, the liquid in the separator contains certain acidic components, while the airbag 1 made of rubber material can avoid the corrosion effect of these acidic components on it.

[0053] Embodiment 2

[0054] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, in this embodiment, the difference from Embodiment 1 is that the filter screen 2 is detachably connected to the inner wall of the liquid accumulation tank 102.

[0055] In this embodiment, the material of the filter screen 2 is usually metal or other materials with a harder texture, which is not convenient to be stored together with the airbag 1. And the filter screen 2 and the airbag 1 adopt a detachable connection method, so that the filter screen 2 and the airbag 1 can be stored separately, playing a role in protecting the airbag 1. At the same time, it is convenient to fold the airbag 1 into a smaller size, facilitating carrying and storage.

[0056] Specifically, clamping grooves 41 are respectively arranged on both sides of the inner wall of the liquid accumulation tank 102. Clamping blocks 21 that are slidably matched with the clamping grooves 41 are respectively arranged on both sides of the filter screen 2. The filter screen 2 is inserted into the clamping grooves 41 on both sides of the inner wall of the liquid accumulation tank 102 through the clamping blocks 21 on both sides thereof, realizing the detachable connection between the filter screen 2 and the airbag 1, and the disassembly and assembly are simple and convenient.

[0057] Furthermore, an installation strip 4 is connected to the inner side wall of the liquid accumulation tank 102. The installation strip 4 is arranged along the height direction of the liquid accumulation tank 102. The clamping groove 41 is arranged on the installation strip 4. The clamping groove 41 is arranged along the length direction of the installation strip 4. In order to maintain portability, the wall of the airbag 1 is set to be relatively thin, so it is not convenient to directly arrange the clamping groove 41 on the wall of the airbag 1. In this solution, by adding the installation strip 4 to the inner wall of the airbag 1 and then arranging the clamping groove 41 on the installation strip 4, the installation of the filter screen in the airbag 1 is realized, and at the same time, the structure of the airbag 1 will not be affected.

[0058] Even further, a fixing strip 5 is arranged on the inner bottom wall of the liquid accumulation tank 102. The fixing strip 5 is provided with a sealing groove 51. The sealing groove 51 is arranged along the length direction of the fixing strip 5. Both ends of the fixing strip 5 are respectively connected to the two installation strips 4. A sealing block 22 is connected to the bottom of the filter screen 2. The sealing block 22 is nested with the sealing groove 51. By adding the fixing strip 5 to the airbag 1, the sealing block 22 at the bottom of the filter screen 2 is nested with the sealing groove 51 on the fixing strip 5, forming a seal at the bottom of the filter screen 2 to prevent sediment from leaking into the clean water cavity 1022 through the gap between the bottom of the filter screen 2 and the inner bottom wall of the airbag 1.

[0059] Embodiment 3

[0060] As Figure 1 shown, in this embodiment, the difference from Embodiment 1 is that a plurality of cable ties 103 are connected to the airbag 1. The plurality of cable ties 103 are arranged around the airbag 1.

[0061] In this embodiment, the airbag 1 can be fixed to the separator through the cable ties 103, or the airbag can be fixed to the pipelines and equipment around the separator, so that the position of the airbag 1 at the bottom of the separator is more stable and not prone to displacement under the action of sewage scouring.

[0062] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
