[0035] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.
[0036] like Figure 2-Figure 4 As shown, a floor drain sand collecting device for an offshore oil and gas platform according to an embodiment of the utility model may include a floor drain body 100 , a primary sand collecting pool 10 installed in the floor drain body 100 , a water sealing cover 20 , a secondary sand collecting pool 30 and a filter funnel 40 .
[0037] After water carrying impurities such as sand enters the floor drain body 100, it undergoes primary sedimentation and coarse filtration in the primary sand collecting pool 10, where most of the impurities are collected; the liquid after passing through the primary sand collecting pool 10 overflows into the secondary sand collecting pool 30 for further sedimentation, and the liquid after the secondary sedimentation overflows into the filter funnel 40 for filtration, and finally is discharged from the floor drain body 100 and enters the open drainage pipe network.
[0038] The floor drain body 100 includes a top inlet 101, a bottom outlet 102, a first chamber 110 and a second chamber 120 formed sequentially between the top inlet 101 and the bottom outlet 102; the top inlet 101, the first chamber 110, the second chamber 120 and the bottom outlet 102 are sequentially connected to form a filtering channel for liquid carrying impurities such as sand to pass through and to be sequentially sedimented and filtered. The primary sand collecting pool 10 is arranged in the first chamber 110, the secondary sand collecting pool 30 is arranged in the second chamber 120, the water seal cover 20 is arranged in the second chamber 120 and is located above the secondary sand collecting pool 30, and the filter funnel 40 is arranged in the bottom outlet 102.
[0039] Specifically, in terms of structure, the floor drain body 100 further includes a first shell 111, a second shell 112 and a hollow cylinder 130 which are connected and communicated in sequence. The first shell 111 is a shell structure with an open top, and its open top forms the top inlet 101 of the floor drain body 100, and the inner cavity of the first shell 111 forms the first chamber 110. The second shell 112 is connected to the side of the first shell 111 away from the top inlet 101, and is communicated with the first shell 111, and the inner cavity of the second shell 112 forms the second chamber 120. The hollow cylinder is connected to the side of the second shell 112 facing away from the first shell 111, and the hollow cylinder 130 is a columnar structure with a hollow interior, thereby forming the bottom outlet 102 of the floor drain cylinder.
[0040] In order to achieve the communication between the first shell 111 and the second shell 112, the bottom surface of the first shell 111 is provided with an opening, which corresponds to the top of the second shell 112. The second shell 112 is connected below the opening with its open top, so that the first chamber 110 and the second chamber 120 are connected through the opening. The hollow cylinder is connected to the second chamber 120 through the opening on the bottom surface of the second shell 112.
[0041] In some embodiments, the outer circumference of the hollow cylinder 130 is smaller than the outer circumference of the second shell 112, and the outer circumference of the second shell 112 is smaller than the outer circumference of the first shell 111, so that the floor drain body 100 formed is smaller in size from top to bottom. When the floor drain body 100 is polygonal (such as rectangular) as a whole, the first shell 111 and the second shell 112 are rectangular shells, and the length and width of the first shell 111 are respectively greater than the length and width of the second shell 112; the hollow cylinder can be a polygonal cylinder or a circular cylinder; for a polygonal cylinder, its length and width are smaller than the length and width of the second shell 112, and for a circular cylinder, its outer diameter is smaller than the length and width of the second shell 112. When the floor drain body 100 is circular as a whole, at least in terms of the inner diameter, the inner diameter of the first shell 111 is greater than the inner diameter of the second shell 112, and the inner diameter of the second shell 112 is greater than the inner diameter of the hollow cylinder 130.
[0042] Preferably, one end of the hollow cylinder 130 facing the second shell 112 also extends into the second chamber 120 to form an upper end of the hollow cylinder 130; the protruding arrangement of the upper end in the second chamber 120 effectively blocks and filters the liquid.
[0043] A grid plate 50 is provided on the top inlet 101 of the floor drain body 100. The grid plate 50 is matched with the top inlet 101 to preliminarily filter the liquid etc. entering the top inlet 101 and intercept the debris whose size is larger than the grid hole of the grid plate 50 outside the floor drain body 100.
[0044] The primary sand collecting pool 10 is installed in the first chamber 110 of the floor drain body 100, that is, it is arranged in the first shell 111, and is located above the second chamber 120. The primary sand collecting pool 10 is used to perform primary sedimentation and coarse filtration on the liquid carrying impurities such as sand particles entering the floor drain body 100. The primary sand collecting pool 10 is provided with an overflow hole 103 connecting the primary sand collecting pool 10 and the second chamber 120, so that the liquid after primary sedimentation and coarse filtration in the primary sand collecting pool 10 can enter the second chamber 120 through the overflow hole 103, and the blocked impurities are collected in the primary sand collecting pool 10. When the impurities in the primary sand collecting pool 10 accumulate to a certain amount, the primary sand collecting pool 10 can be taken out of the first shell 111 to clean the impurities.
[0045] The primary sand collecting pool 10 may further include a sand collecting box 113 with an open top and an inner partition 114, wherein the inner partition 114 is disposed in the sand collecting box 113. The sand collecting box 113 is used for allowing liquid to flow in and accommodating impurities for sedimentation and filtration, and the inner partition 114 filters the liquid with impurities in the sand collecting box 113, and traps the impurities and the like in the sand collecting box 113.
[0046] As an option, the outer peripheral shape of the sand collecting box 113 can be set corresponding to the first shell 111, for example, a polygon or a circle, etc. Of course, the outer peripheral shape of the sand collecting box can also be inconsistent with the first shell 111, as long as it can fit above the second shell 112, cover the opening connecting the first shell 111 and the second shell 112, and have enough space to accommodate the impurities that are settled and filtered. In addition, the setting of the sand collecting box 113 being smaller in size than the first shell 111 is conducive to the smooth removal and placement of the primary sand collecting pool 10.
[0047] The bottom surface of the sand collecting box 113 is provided with a through hole 104, and the inner partition 114 is connected to the through hole 104 in a circumferential direction corresponding to the through hole; the overflow holes 103 are provided on the peripheral wall of the inner partition 114, for example, distributed at intervals along the peripheral wall of the inner partition 114. In the floor drain body 100, the inner cavity of the sand collecting box 113 is connected to the second chamber 120 through the overflow holes 103 and the through holes 104.
[0048] The aperture of the through hole 104 is greater than or equal to the inner diameter of the top of the second chamber 120 connecting the first chamber 110 (the inner diameter of the opening connecting the first shell 111 and the second shell 112 ), ensuring the filtering effect and water intake.
[0049] There is a gap between the overflow hole 103 on the inner partition 114 and the bottom surface of the sand collecting box 113, so that the overflow hole 103 has a certain height for settling sand particles, and water naturally overflows and enters the next stage of settling.
[0050] The inner partition 114 may further include an annular side wall 121 and a cover plate 122. The annular side wall 121 is connected to the through hole 104 of the sand collecting box 113, and the cover plate 122 is detachably covered on the annular side wall 121 to seal the top of the annular side wall 121 to prevent the liquid from directly entering the second chamber 120 without sedimentation filtration. The overflow hole 103 is specifically opened on the annular side wall 121 of the inner partition 114, and a gap is left between the lower edge of the overflow hole 103 and the bottom surface of the sand collecting box 113.
[0051] The water seal cover 20 is arranged in the second chamber 120 and covers the bottom outlet 102, and is located below the inner partition 114 of the primary sand collecting pool 10. In combination with the structure of the floor drain body 100, the water seal cover 20 is specifically arranged in the second shell 112 of the floor drain body 100, and the water seal cover 20 is located in the upper end of the second chamber 120, and the entire second chamber 120 or the lower end of the second chamber 120 forms a secondary sand collecting pool 30.
[0052] The water seal cover 20 is a cover body with an arc or an arch, and can use the hydrostatic pressure above the bottom outlet 102 to prevent the gas in the drain pipe from entering the indoor space where the floor drain is located.
[0053] In the second shell 112, a gap is left between the outer periphery of the water seal cover 20 and the inner wall of the second shell 112, and the liquid passes through the first sand collecting pool 10 and enters the lower end of the second chamber 120 along the gap; impurities such as sand and gravel in the liquid are settled and filtered in the second sand collecting pool 30, and the liquid then enters the bottom outlet 102.
[0054] The first chamber 110 and the second chamber 120 cooperate with the primary sand collecting pool 10 and the secondary sand collecting pool 30 therein to not only realize two-stage sedimentation filtration, but also have two-stage chambers to collect impurities. Compared with the primary sand collecting pool 10, the secondary sand collecting pool 30 has fewer impurities and a larger water capacity, which helps to improve the water seal and make drainage smoother.
[0055] The secondary sand collecting pool 30 is arranged in the second chamber 120, and there is no need to arrange structural parts such as the water seal cover 20 support ribs therein, thereby solving the problems of difficult cleaning of impurities, incomplete cleaning, and time-consuming labor.
[0056] In some embodiments, one end of the hollow cylinder 130 is extended into the second chamber 120 to form the upper end of the hollow cylinder 130, and the upper end is protruding in the second chamber 120. After passing through the secondary sand collecting pool 30, impurities such as sand and gravel settled therein can be blocked at the outer periphery of the upper end of the hollow cylinder 130, and the liquid overflows into the bottom outlet 102.
[0057] To prevent the water seal cover 20 from closing and sealing on the bottom outlet 102, refer to Figure 3 The water seal cover 20 is covered above the upper end of the hollow cylinder 130 through the support frame 60, and is also located above the bottom outlet 102. The support frame 60 is a frame structure and will not block liquids and the like.
[0058] The filter funnel 40 is positioned in the bottom outlet 102. In some embodiments, the filter funnel 40 is accommodated in the upper end of the hollow cylinder 130. The filter funnel 40 is a cylinder with open ends as a whole, and the side wall of the cylinder is covered with filter holes; and the cylinder has a conical structure, and the inner diameter (or outer diameter) gradually decreases from one end to the other end. The filter funnel 40 is loaded into the bottom outlet 102 with the end with a smaller inner diameter; the end of the filter funnel 40 with a larger inner diameter fits in the end of the bottom outlet 102 connected to the second chamber 120, and the outer diameter of this end is equivalent to the inner diameter of this end of the bottom outlet 102. The setting of the conical structure is convenient for taking and placing the filter funnel 40.
[0059] like Figure 4 and Figure 5 As shown, in a preferred embodiment, the support frame 60 is connected to the top of the filter funnel 40, or is formed integrally with the filter funnel 40, so that when the filter funnel 40 is set in the bottom outlet 102, the support frame 60 can be supported above the bottom outlet 102 (i.e., on the top of the hollow cylinder 130), which is not only used to support the water sealing cover 20 above, but also to position the filter funnel 40 so that it will not fall freely out of the bottom outlet 102. In addition, the connection between the support frame 60 and the filter funnel 40 also reduces the structural parts of the floor drain, which is more convenient and quick to install.
[0060] In order to prevent rust, the sand collecting device for the floor drain of the offshore oil and gas platform of the utility model is made of water-resistant corrosion materials such as stainless steel or plastic materials as a whole or at least the first-level sand collecting pool 10.
[0061] After the floor drain sand collecting device of the utility model is applied to an offshore oil and gas platform, the floor drain cleaning efficiency can be increased to 150 pieces / man-hour, effectively avoiding blockage of the floor drain discharge pipeline.
[0062] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
