Description

Technical Field

[0001] This utility model relates to the field of salt gas treatment in salt mud ponds, specifically to a steel-lined glass-enclosed anti-corrosion device for salt mud ponds. Background Technology

[0002] The salt mud tank is an open-top reinforced concrete tank designed to receive the salt mud solution discharged from equipment such as the pre-processor, reaction tank, Kelvin membrane filter, and inorganic membrane filter during the brine refining process. In actual operation, compressed air is used to continuously agitate the medium in the salt mud tank to prevent sedimentation. This agitation generates a large amount of salt gas that disperses around the tank, causing varying degrees of corrosion to the surrounding equipment, pipes, and pipe racks.

[0003] To prevent salt gas from drifting around the salt mud pool, the existing technology involves laying a cover cloth over the salt mud pool using a supporting frame. However, this protective measure is not very effective, and it is difficult to observe the real-time conditions inside the salt mud pool during the protection process.

[0004] Therefore, a steel-lined glass-enclosed anti-corrosion device for salt mud ponds is needed to solve the above-mentioned technical problems. Utility Model Content

[0009] Furthermore, as a preferred embodiment, the turntable includes: a turntable body, a retaining ring, a polygonal groove, and a reset post; The disc body has an annular structure, and a retaining ring is provided on its outer side wall. The retaining ring is rotatably connected to the annular groove. The disk body has the polygonal groove, and six sets of the reset posts are arranged around the circumference of the disk body.

[0010] Furthermore, as a preferred embodiment, the frame includes: a fixed plate, an inclined groove, an arc groove, and an elastic element; The fixed disk is a ring structure and is fixedly connected to the cover plate by the right-angle rod. The fixed disk has six sets of inclined grooves that penetrate it on its circumference.

[0011] Furthermore, as a preferred embodiment, the opening and closing plate includes: a plate body, a lower sliding column, and an upper sliding column; The opening and closing plates are configured in six groups, and each group of opening and closing plates has an upper sliding column at the top of the plate and a lower sliding column at the bottom. The upper sliding column is slidably connected to the inclined groove, and the lower sliding column is slidably connected to the polygonal groove. The six sets of plates are slidably connected between the frame and the turntable along the circumferential direction by means of the upper sliding column and the lower sliding column.

[0012] Furthermore, as a preferred embodiment, the protective cover includes: a cover body, a monitoring ring, and a reset mark; The cover body matches the shape of the fixed plate, and the cover body is detachably installed on the fixed plate; The monitoring ring is provided on the inner side wall of the enclosure; The reset mark is installed on the surface of the cover.

[0014] Compared with the prior art, this utility model provides a steel-lined glass-enclosed anti-corrosion device for salt mud ponds, which has the following beneficial effects: Advantage 1: To facilitate real-time observation of the salt mud pool during salt gas protection, this invention replaces the original support frame and cover cloth protection with a cover plate and steel beam protection, significantly improving the protective effect. Multiple sets of steel beams are installed at equal intervals along the long side of the salt mud pool opening. Adjacent steel beams are connected by cover plates. The cover plate, located within the guardrail assembly, serves as an inspection channel. An agitator is installed on this cover plate to stir the substances in the salt mud pool.

[0015] Advantage 2: This invention enables two monitoring methods for salt gas leakage: a monitoring ring and a resetting marker. The coexistence of these two methods, combined with the cover plate and steel beam design, effectively prevents large amounts of salt gas from dispersing around the salt mud pool, thus avoiding varying degrees of corrosion to surrounding equipment, pipes, and pipe racks.

[0016] Advantage 3: This utility model uses a pulling device to drive the opening and closing device to switch between open and closed states. Therefore, this utility model will not cause the situation where the observation port remains unclosed after the staff forgets to close it and leaves after the observation is completed. This further avoids the phenomenon of a large amount of salt gas leakage in the salt mud pool. Attached Figure Description

[0018] Please see Figures 1-7 This utility model provides a steel-lined glass-enclosed anti-corrosion device for a salt mud pond, comprising: a salt mud pond 1, a steel beam 2, a cover plate 3, an observation port 4, an opening and closing device 5, and a pulling device 6. The salt mud pool 1 is provided with multiple sets of steel beams 2, and each set of steel beams 2 is connected to a cover plate 3; Two of the multiple sets of cover plates 3 are provided with observation ports 4, and each set of observation ports 4 is equipped with the opening and closing device 5; Each of the opening and closing devices 5 is equipped with the pulling device 6.

[0019] Furthermore, a guardrail assembly 7 is installed on one of the cover plates 3. The guardrail assembly 7 is a frame structure. A ladder 8 is provided on the side of the guardrail assembly 7 near the salt mud pool 1. The end of the ladder 8 away from the guardrail assembly 7 is connected to the ground.

[0020] Furthermore, a stirrer 9 is also provided on the cover plate 3 on which the guardrail assembly 7 is installed, and two sets of observation ports 4 are respectively opened on the cover plate 3 at positions close to the stirrer 9 and far away from the stirrer 9; An annular groove is provided on the inner wall of the observation port 4.

[0021] In this embodiment, to facilitate real-time observation of the condition inside the salt mud pool 1 during the salt gas protection process, the original protective form of the support frame and cover cloth is changed to a protective form of cover plate 3 and steel beam 2.

[0022] Specifically: Please refer to Figure 1 As shown, multiple sets of steel beams 2 are installed at equal intervals along the long side of the opening of the salt mud pool 1. Adjacent steel beams 2 are connected by cover plates 3. The cover plate 3 located inside the guardrail assembly 7 serves as an inspection channel. An agitator 9 is installed on this cover plate 3 to agitate the substances in the salt mud pool 1.

[0023] Two sets of observation ports 4 are provided on the cover plate 3. The observation port 4 closer to the agitator 9 is the agitation observation port, and the observation port 4 further away from the agitator 9 is the dead zone observation port. Workers can access the inspection passage via the escalator 8 and observe the materials in the salt mud tank 1 in real time through the two sets of observation ports 4. The agitation observation port is used to observe the agitation of the materials in the salt mud tank 1 by the agitator 9, and the dead zone observation port is used to observe the accumulation of mud in dead corners within the salt mud tank 1. Workers can choose to open the corresponding observation port 4 according to the specific object being observed.

[0024] To prevent salt gas from leaking out of the two sets of observation ports 4 in the salt mud pool 1, this utility model is equipped with opening and closing devices 5 on the two sets of observation ports 4 respectively. The staff can open the opening and closing devices 5 by pulling the device 6, thereby completing the observation task.

[0025] It should be noted that steel beam 2 is a pure fiberglass double-reinforced I-beam structure with a salt-corrosion resistant outer layer. The cover plate 3 located within the guardrail assembly 7 is made of steel-lined fiberglass, with its side closest to the interior of the salt mud pool 1 evenly covered with glass flakes for corrosion protection. The remaining cover plates 3 are all made of pure fiberglass, which itself has salt-corrosion resistant properties. To ensure the safety of the inspection passage, this invention also installs a reinforcing beam perpendicular to steel beam 2 (this steel beam 2 is made of a different material than the other steel beams 2, being steel-lined fiberglass) at the lower end of the cover plate 3 at the inspection passage location. This reinforcing beam is an I-beam structure. Both the guardrail assembly 7 and the handrail 8 undergo surface anti-corrosion treatment.

[0026] Furthermore, the opening and closing device 5 includes: a turntable 51, a frame 52, an opening and closing plate 53, and a protective cover 54; The outer wall of the turntable 51 is rotatably connected to the inner wall of the observation port 4, and the frame 52 is fixedly connected to the cover plate 3 by a right-angle rod. The opening and closing plates 53 are configured in multiple sets, and the multiple sets of opening and closing plates 53 are slidably connected between the frame 52 and the turntable 51.

[0027] Furthermore, the turntable 51 includes: a disc body 511, a retaining ring 512, a polygonal groove 513, and a reset post 514; The disc body 511 has an annular structure, and a retaining ring 512 is provided on its outer side wall. The retaining ring 512 is rotatably connected to the annular groove. The disk body 511 has a polygonal groove 513, and six sets of reset posts 514 are arranged around the circumference of the disk body 511.

[0028] Furthermore, the frame 52 includes: a fixed plate 521, an inclined groove 522, an arc groove 523, and an elastic element 524; The fixed disk 521 has a ring structure and is fixedly connected to the cover plate 3 by the right-angle rod. The fixed disk 521 has six sets of inclined grooves 522 that penetrate it on its circumference. The fixed disk 521 has six sets of arc grooves 523 circumferentially formed on the outer side of the inclined groove 522, and each set of arc grooves 523 does not penetrate the fixed disk 521; Each set of the arc grooves 523 is provided with an elastic element 524, and the six sets of reset posts 514 are slidably connected to each set of the arc grooves 523 and are all connected to the elastic element 524 located in each set of the arc grooves 523.

[0029] Furthermore, the opening and closing plate 53 includes: a plate body 531, a lower sliding column 532, and an upper sliding column 533; The opening and closing plates 53 are configured in six groups. Each group of opening and closing plates 53 has an upper sliding column 533 at the top of the plate body 531 and a lower sliding column 532 at the bottom. The upper sliding column 533 is slidably connected to the inclined groove 522, and the lower sliding column 532 is slidably connected to the polygonal groove 513. The six sets of plates 531 are slidably connected to the frame 52 and the turntable 51 along the circumferential direction by means of the upper sliding column 533 and the lower sliding column 532.

[0030] In this embodiment, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the disc body 511 is in the initial position, the six sets of opening and closing plates 53 will close tightly along the circumferential direction to block the observation port 4. At this time, the reset column 514 located in the arc groove 523 is also in the initial state (i.e., the elastic element 524 is not compressed).

[0031] In a preferred embodiment, the rotation of the disc 511 is facilitated by the combined action of the polygonal groove 513 and the inclined groove 522, which drives the six sets of opening and closing plates 53 to rotate from a sequentially closed state to an open state. Simultaneously, the reset pin 514 on the disc 511 rotates synchronously and compresses the elastic element 524 located within the arc groove 523. At this point, the elastic element 524 enters a stored state, thus completing the opening operation of the opening and closing device 5, allowing the operator to begin observation.

[0032] Furthermore, the protective cover 54 includes: a cover body 541, a monitoring ring 542, and a reset mark 543; The cover 541 is shaped to match the fixed plate 521, and the cover 541 is detachably mounted on the fixed plate 521. The monitoring ring 542 is provided on the inner wall of the cover 541; The reset mark 543 is installed on the surface of the cover 541.

[0033] In this embodiment, please refer to Figure 6 As shown, the cover 541 is detachably mounted on the fixed plate 521. In other words, the protective cover 54 can protect the opening and closing device 5 to prevent the components in the opening and closing device 5 from being damaged by external interference. The cover 541 is also made of a salt gas corrosion resistant material.

[0034] In a preferred embodiment, this invention enables a first method for monitoring salt gas leakage, which is monitoring by a monitoring ring 542. Specifically, a monitoring ring 542 is located on the inner wall of the enclosure 541. This monitoring ring 542 is equipped with multiple sets of salt gas monitoring elements. When the opening and closing device 5 is in the closed state, the six sets of opening and closing plates 53 in the opening and closing device 5 can be monitored in real time at their closed positions. If a salt gas leakage occurs, the salt gas monitoring elements on the monitoring ring 542 will issue an alarm to alert the personnel.

[0035] Furthermore, the pulling device 6 includes: a first fixed end 61, a second fixed end 62, a guide member 63, and a pulling rope 64; The first fixed end 61 is fixedly connected to the outer wall of the disc body 511 at the position above the retaining ring 512; The second fixed end 62 is fixedly connected to the guardrail assembly 7; The number of guide members 63 is configured as multiple groups, and the multiple groups of guide members 63 are staggered on the cover plate 3; The first fixed end 61, the second fixed end 62 and the plurality of guide members 63 are connected by the pull rope 64.

[0036] In this embodiment, please refer to Figure 7 As shown, the rotational power of the turntable 51 is generated by the worker through the pulling device 6. Specifically, all four sections of the pulling rope 64 are initially taut. The worker stands near the second fixed end 62 and pulls section A of the pulling rope 64. Section A of the pulling rope 64 changes from a taut state to a slack state, while sections B, C, and D remain taut. At the same time, with the help of multiple sets of guide members 63 and the first fixed end 61, the turntable 51 is rotated, thereby opening the opening and closing device 5.

[0037] It is important to note that when the opening / closing device 5 is in the open state, the elastic element 524 is in a stored state. Therefore, the operator of the pulling device 6 must not release the pulling rope 64; instead, an assistant should perform the observation operation. Only after the observation is completed can the operator release the pulling rope 64. The elastic element 524 then transitions from a stored state to a released state. Under the action of the elastic element 524, the turntable 51 returns to its initial position, and the opening / closing device 5 closes. Therefore, this invention prevents the situation where the observation port 4 remains open after the operator forgets to close it, thus further avoiding a large leakage of salt gas from the salt mud pool 1.

[0038] In a preferred embodiment, when the turntable 51 is in its initial position, the first fixed end 61 and the reset mark 543 located on the cover 541 are flush. Therefore, this invention can realize a second method of monitoring salt gas leakage, which is monitoring the reset mark 543. That is, when the turntable 51 fails to return to its initial state due to the elastic element 524 or other problems, the first fixed end 61 and the reset mark 543 will be in a non-flush position. Workers can observe the relative position between the first fixed end 61 and the reset mark 543 to determine whether the opening and closing device 5 is completely closed, thereby realizing the monitoring of salt gas leakage in the salt mud pool 1.

[0039] It should be noted that the number and installation position of the guide components 63 can be determined according to specific circumstances, as long as it allows the operator to smoothly operate the pulling device 6. The guide components 63 can be existing common pulleys with grooves, or other components, as long as they can realize the function of the pulling device 6. In this utility model, all components connected to the observation port 4 are sealed connections.

[0040] In practice, multiple sets of steel beams 2 are installed at equal intervals along the long side of the opening of the salt mud pool 1. Adjacent steel beams 2 are connected by cover plates 3. The cover plate 3, located within the guardrail assembly 7, serves as an inspection channel. An agitator 9 is installed on this cover plate 3 to agitate the materials in the salt mud pool 1. Two sets of observation ports 4 are provided on the cover plate 3. The observation port 4 closer to the agitator 9 is the agitation observation port, and the observation port 4 further away from the agitator 9 is the dead angle observation port. Workers can access the inspection channel via the escalator 8 and observe the materials in the salt mud pool 1 in real time through the two sets of observation ports 4. The agitation observation port is used to observe the agitator 9's agitation of the materials in the salt mud pool 1, and the dead angle observation port is used to observe the accumulation of mud in dead corners of the salt mud pool 1. Workers can choose to open the corresponding observation port 4 according to the specific object of observation.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
