Description

Technical Field

[0001] This invention belongs to the field of marine mud storage technology, and specifically relates to a marine mud storage tank. Background Technology

[0002] Marine mud, as a special type of marine sediment, has important application value in marine engineering, environmental management, and resource recycling. However, due to its high content of salt, hydrogen sulfide, acidic substances, and gravel, marine mud is highly corrosive, abrasive, and prone to caking. In existing marine mud storage tanks, the mud directly contacts the inner wall, bottom, and lid of the tank during storage. Over time, the high corrosiveness and abrasiveness of the marine mud will cause corrosion and wear of the metal tank, leading to leakage risks during use. Furthermore, once the tank is corroded, it will also bring challenges in cleaning, maintenance, and replacement. Summary of the Invention

[0003] In order to overcome the shortcomings pointed out in the background art above, the present invention provides a marine mud storage tank.

[0004] The technical implementation of the present invention is as follows: a marine mud storage tank includes a tank body installed in a protective frame, the tank body being provided with a discharge port, the tank body being provided with a cover, a side wall liner being detachably connected to the tank body and sealingly fitted with the cover, the side wall liner being provided with a first channel communicating with the discharge port, the cover being threadedly connected with a screw, the screw being threadedly connected to an upper liner, the upper liner being sealingly fitted with the cover, and the tank body being provided with a lower liner sealingly fitted with the lower side of the side wall liner.

[0005] To further explain, the side wall liner and the upper liner are sealed together, and the lower liner is provided with a sealing part that is slidably connected to the tank body. The thickness of the sealing part is greater than the thickness of the lower liner inside the tank body.

[0006] To further explain, the inner wall lining is provided with spaced recesses, which makes the inner edge of the vertical section of the inner wall lining wavy.

[0007] To further explain, the inner sleeve is slidably connected to the inner wall liner for limiting and sealing. An elastic element is fixed between the inner sleeve and the inner wall liner. The inner sleeve is sealed and fitted to the lower inner liner. The inner sleeve is provided with a second channel communicating with the first channel.

[0008] To further explain, the tank body is provided with a limiting groove, and the side wall lining is fixedly connected with a limiting block that slides within the limiting groove.

[0009] To further explain, the upper side of the limiting groove is provided with an opening, the width of which is greater than the width of the limiting block.

[0010] To further explain, the inner lining of the side wall is provided with several sets of stirring blades arranged at intervals, and each set of stirring blades has several stirring blades arranged circumferentially.

[0011] To further explain, the width of the stirring blade gradually increases from the top and bottom sides to the middle.

[0012] To further explain, the stirring blades in the same group are all fixedly connected to an extrusion block, and the cross-sectional area of ​​the extrusion block gradually increases from the top and bottom sides to the middle.

[0013] To further explain, the volume of the extrusion blocks, which are spaced apart vertically, decreases sequentially from top to bottom.

[0014] The advantages and positive effects of this invention compared to existing technologies are as follows: This invention isolates marine mud through sidewall linings, an upper lining, and a lower lining, reducing the probability of corrosion and abrasion of the tank and lid due to direct contact between the marine mud and the inner walls of the tank and lid. This reduces the risk of leakage after corrosion and abrasion of the tank and lid. Furthermore, the sidewall linings, upper lining, and lower lining are designed to be detachable, facilitating disassembly and replacement of these linings, thereby reducing the cleaning costs of the marine mud storage tank. The maintenance is difficult, and by utilizing the reciprocating movement of all the recesses on the sidewall liner, the spatial area of ​​each layer of marine mud in the sidewall liner is constantly changing, so as to enhance the fluidity of the marine mud, reduce the probability of marine mud deposition and caking, and improve the discharge efficiency of marine mud. By moving the sidewall liner up and down and rotating back and forth, the relative displacement between each layer of marine mud and the sidewall liner is generated, and the sidewall liner drives the stirring blade to rotate, which agitates the marine mud, thereby reducing the probability of marine mud adhering and caking on the sidewall liner and improving the efficiency of marine mud discharge.

Detailed Implementation

[0023] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0024] Example 1

[0025] During storage, the existing marine mud comes into direct contact with the inner wall and lid of the tank. Over time, this can lead to rapid corrosion and wear of the metal tank, and even leakage.

[0026] A type of marine mud storage tank, such as Figures 1-3 As shown, the tank includes a tank 2 installed within a protective frame 1. The protective frame 1 is used to reinforce the tank 2 to reduce the probability of the tank 2 tilting or even collapsing. A discharge port 201 is provided on the lower left side of the tank 2. A cover 3 is installed on the tank 2, and a first inlet for injecting marine mud is provided on the cover 3. A side wall liner 4 is detachably connected to the tank 2 and is sealed to the cover 3. When the side wall liner 4 needs to be replaced, the cover 3 is opened, and then the side wall liner 4 is lifted upward by external hoisting equipment, so that the side wall liner 4 is detached from the tank 2. The side wall liner 4 has spaced recesses, so that the inner edge of the vertical section of the side wall liner 4 is wavy. By moving the side wall liner 4 up and down, all the recesses on the side wall liner 4 are removed. The tank moves up and down to squeeze the mud inside the side wall liner 4. The side wall liner 4 is provided with a first channel 401 that communicates with the discharge port 201. The cover 3 is threaded with a screw 6, and the screw 6 is threaded with an upper liner 5. The upper liner 5 is provided with a second feed port that communicates with the first feed port. The upper liner 5 is sealed and fitted with the cover 3. After the cover 3 is opened, the upper liner 5 is detached from the cover 3 by unscrewing the screw 6. The tank 2 is provided with a lower liner 7 that is sealed and fitted with the lower side of the side wall liner 4. The lower liner 7 is detached from the tank 2 by pulling it to the right. The side wall liner 4, the upper liner 5, and the lower liner 7 are all made of wear-resistant materials (such as ceramics and polymers) to improve the wear resistance of the side wall liner 4, the upper liner 5, and the lower liner 7.

[0027] like Figure 3 , Figure 5 and Figure 6 As shown, the side wall liner 4 and the upper liner 5 are sealed together. The lower liner 7 is provided with a sealing part 701 that is slidably connected to the tank body 2 to reduce the probability of the marine mud coming into contact with the inner wall of the tank body 2. The thickness of the sealing part 701 is greater than the thickness of the left side of the lower liner 7. During the process of the lower liner 7 moving to the right, the probability of the marine mud accumulated on the left side of the lower liner 7 coming into contact with the tank body 2 is reduced.

[0028] like Figure 3 , Figure 6 and Figure 7 As shown, the inner sleeve 8 is slidably connected to the inner wall liner 4 for limiting and sealing. An elastic element is fixed between the inner sleeve 8 and the inner wall liner 4, wherein the elastic element is a compression spring. The inner sleeve 8 is made of wear-resistant material (such as ceramic and polymer material). Initially, the inner sleeve 8 is sealed and fitted with the lower inner liner 7. The elastic element between the inner sleeve 8 and the inner wall liner 4 is in a compressed and stored state. When the inner wall liner 4 moves upward, the elastic element between the inner sleeve 8 and the inner wall liner 4 pops out, causing the inner wall liner 4 to move relative to the inner sleeve 8. When the inner wall liner 4 moves upward, it covers the inner wall of the tank body 2 through the inner sleeve 8. The inner sleeve 8 is provided with a second channel 801 that communicates with the first channel 401.

[0029] Specific working principle:

[0030] When operators need to use this device to store marine mud, they open the first inlet of the cover 3 and inject the marine mud into the tank 2 through the first inlet of the cover 3 and the second inlet of the upper inner liner 5. The side wall liner 4, upper inner liner 5, and lower inner liner 7 isolate the marine mud to reduce the probability of corrosion and abrasion of the tank 2 and cover 3 due to direct contact between the marine mud and the inner walls of the tank 2 and cover 3. This reduces the risk of leakage after corrosion and abrasion of the tank 2 and cover 3. After the marine mud in the tank 2 is emptied (when it is necessary to discharge the marine mud, open the discharge port), the operation is complete. 201. Marine mud is discharged through the first channel 401, the second channel 801 and the discharge port 201 (the operator collects the marine mud). The operator opens the cover 3 and lifts the side wall liner 4 upward with the external hoisting equipment, so that the side wall liner 4 is separated from the tank body 2. By unscrewing the screw 6, the upper liner 5 is separated from the cover 3. By pulling the lower liner 7 to the right, the lower liner 7 is separated from the tank body 2. The side wall liner 4, the upper liner 5 and the lower liner 7 are removed to facilitate the disassembly and replacement of the side wall liner 4, the upper liner 5 and the lower liner 7, thereby reducing the difficulty of cleaning and maintaining the marine mud storage tank.

[0031] When it is necessary to discharge marine mud, open the discharge port 201 and the cover 3, and use external hoisting equipment to drive the side wall liner 4 to move up and down (during the up and down movement of the side wall liner 4, the elastic element between the inner sleeve 8 and the side wall liner 4 pops out, so that the inner sleeve 8 is temporarily stationary, and the inner sleeve 8 protects the lower side wall of the tank 2 to reduce the probability of direct contact between the marine mud and the tank 2). All the recesses on the side wall liner 4 move up and down, so that the spatial area of ​​each layer of marine mud in the side wall liner 4 changes continuously, so as to enhance the fluidity of the marine mud, reduce the probability of marine mud deposition and caking, and improve the discharge efficiency of marine mud.

[0032] After the sea mud is drained, the disassembled side wall liner 4, upper liner 5 and lower liner 7 are cleaned and maintained. If the side wall liner 4, upper liner 5 and lower liner 7 are damaged, they are replaced. Then the lower liner 7 is inserted into the tank 2 for repositioning. The side wall liner 4 is inserted into the tank 2, and the upper liner 5 is fixed to the cover 3 with screws 6.

[0033] Example 2

[0034] During the static storage process, existing marine mud will settle and harden inside the tank, which will make it difficult to discharge the marine mud and thus affect the discharge efficiency.

[0035] Based on Example 1, such as Figure 2 and Figure 4 As shown, a limiting groove 9 is provided inside the tank body 2, and a limiting block 10 is fixedly connected to the side wall liner 4 and slides within the limiting groove 9. Both the limiting groove 9 and the limiting block 10 are inclined so that when the side wall liner 4 moves up and down, the limiting block 10 slides along the limiting groove 9. The side wall liner 4 rotates during the up and down movement. An opening is provided on the upper side of the limiting groove 9, and the width of the opening is greater than the width of the limiting block 10 so that the limiting block 10 can enter and exit the limiting groove 9. During the up and down movement and reciprocating rotation of the side wall liner 4, a relative displacement occurs between the marine mud as a whole and the inner wall of the side wall liner 4, reducing the probability of marine mud adhering to and caking on the side wall liner 4, thereby improving the efficiency of marine mud feeding and reducing the impact of caking on the storage tank.

[0036] Example 3

[0037] Based on Example 2, such as Figure 3 , Figure 5 and Figure 6As shown, the inner lining 4 of the side wall is provided with several sets of stirring blades 11 arranged vertically at intervals. Each set of stirring blades 11 contains several circumferentially distributed stirring blades 11. During the vertical movement and reciprocating rotation of the inner lining 4 of the side wall, the stirring blades 11 stir the marine mud to enhance its fluidity. The width of the stirring blades 11 gradually increases from the upper and lower sides to the middle. Taking the rear stirring blade 11 as an example, the rear stirring blade 11... Figure 1 The orthographic projection in the main view direction is a rhombus to guide the marine mud, thereby reducing the probability of marine mud adhering to the side wall of the stirring blade 11.

[0038] like Figure 3 and Figure 5 As shown, extrusion blocks 12 are fixedly connected to the stirring blades 11 in the same group. The cross-sectional area of ​​the extrusion blocks 12 gradually increases from the upper and lower sides to the middle. When the extrusion blocks 12 move up and down through the stirring blades 11, the extrusion blocks 12 extrude the sea mud. The volume of the extrusion blocks 12, which are distributed at intervals, decreases from top to bottom. When all the extrusion blocks 12 move downward, the sea mud located below them is extruded by the extrusion blocks 12, increasing the pressure on the sea mud below the extrusion blocks 12, thereby increasing the discharge rate of the sea mud.

[0039] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
