[0001] The utility model relates to the technical field of chemical equipment, in particular to a liquid sodium cyanide finished product storage tank. Background Art

[0002] Sodium cyanide: highly toxic, can produce trace amounts of hydrogen cyanide gas in the air, and must be kept in a sealed, dry, and light-proof place. Its aqueous solution will polymerize at temperatures above 25°C, and may solidify at temperatures below 0°C.

[0003] Storage tanks are used to store refined chemicals such as acids, alkalis, alcohols, gases, and liquids. They are widely used in North China and generally include polyethylene tanks, polypropylene tanks, fiberglass reinforced plastic tanks, ceramic tanks, rubber tanks, and stainless steel tanks, depending on their material. Storage tanks are used to store refined chemicals such as acids, alkalis, alcohols, gases, and liquids. Storage tanks are widely used in North China and generally include polyethylene tanks, polypropylene tanks, fiberglass reinforced plastic tanks, ceramic tanks, rubber tanks, and stainless steel tanks, depending on their material.

[0004] Sodium cyanide itself is a hazardous chemical, so the storage conditions require very strict. Once a storage tank storing sodium cyanide leaks, personnel are needed to check the leak point on the one hand, and to repair the leak point on the other hand. The continuous leakage of sodium cyanide will endanger the staff and is very unsafe. Utility Model Content

[0005] (1) Technical issues to be resolved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the utility model provides a liquid sodium cyanide finished product storage tank, which solves the technical problem that when a storage tank storing sodium cyanide leaks, it is dangerous for workers to repair it.

[0007] (2) Technical solution

[0008] In order to achieve the above-mentioned purpose, the main technical solutions adopted by this utility model include:

[0009] An embodiment of the present invention provides a liquid sodium cyanide finished product storage tank, comprising a transfer tank buried underground and a storage tank fixed to the ground and located directly above the transfer tank, the storage tank and the transfer tank being connected, the top of the transfer tank being provided with a plurality of lower leakage pipes connected to the bottom wall inside the storage tank, the top of the transfer tank being provided with a plurality of vent pipes connected to the top wall inside the storage tank, the storage tank and the transfer tank being provided with sealing plates rotatably provided at the upper and lower ends of the lower leakage pipes for blocking the upper and lower openings of the lower leakage pipes, the sealing plates opening the upper and lower ends of the lower leakage pipes when a leak occurs in the storage tank, the vent pipe being provided with a sealed plate blocking the top opening, the sealed plate opening the vent pipe when a leak occurs in the storage tank.

[0010] The embodiment of the present invention provides a liquid sodium cyanide finished product storage tank. When the liquid sodium cyanide finished product is stored in the liquid sodium cyanide finished product storage tank, the sodium cyanide is directly injected into the storage tank for storage. Once the storage tank leaks, the sealing plates at both ends of the lower leakage pipe are directly opened, so that the sodium cyanide in the storage tank leaks directly into the transfer tank along the lower leakage pipe. When the sealing plates are opened, the air pressure between the storage tank and the transfer tank can be balanced, so that the sodium cyanide can enter the transfer tank more quickly. After the transfer of sodium cyanide is completed, the two ends of the lower leakage pipe can be closed by the sealing plates. At this time, relevant personnel approach the liquid sodium cyanide finished product storage tank for maintenance. This solution can stop the leakage of the liquid sodium cyanide finished product in time after it occurs, avoid continuous leakage, and thus improve the safety of the repair personnel.

[0011] Optionally, a pollution-proof bottom plate is horizontally provided at the lower end of the transfer tank, and an anti-pollution side plate is vertically provided on the outer peripheral side end of the anti-pollution bottom plate, and part of the anti-pollution side plate extends to the ground, and soil is filled between the anti-pollution bottom plate and the end of the anti-pollution side plate.

[0012] By setting an anti-pollution bottom plate at the lower end of the transfer tank and vertically integrating anti-pollution side plates around the side ends of the anti-pollution bottom plate, when the storage tank leaks, the leaked liquid sodium cyanide will flow between the anti-pollution bottom plate and the anti-pollution side plates, thereby reducing the risk of further diffusion of the liquid sodium cyanide. At the same time, soil is filled between the anti-pollution bottom plate and the anti-pollution side plates. On the one hand, the leaked liquid sodium cyanide directly dissolves in the soil, reducing the risk of large-scale volatilization and making it safer. On the other hand, the soil can support the storage tank.

[0013] Optionally, a circle of slide rails is coaxially provided on the upper end of the anti-pollution side plate, and a monitoring camera is slidably provided on the slide rails, and the camera end of the monitoring camera is continuously aimed at the storage tank.

[0014] By coaxially setting a circle of sliding rails at the upper end of the anti-pollution side panel, the monitoring camera can slide along the length of the sliding rails. At this time, the monitoring camera performs a circular motion around the storage tank. While moving in a circular motion, the shooting end of the monitoring camera continues to be aimed at the storage tank, thereby performing real-time and all-round video monitoring of the storage tank, which is safer.

[0015] Optionally, floating pedals horizontally connected to the side ends of the storage tank are evenly spaced at the upper ends of the anti-pollution side plates near the inner circumferential wall of the storage tank, and the floating pedals are located on the upper side of the soil filled between the anti-pollution bottom plate and the anti-pollution side plates.

[0016] By horizontally setting a floating pedal between the anti-pollution side panel and the storage tank, the floating pedal is located on the upper side of the soil. When a leak occurs in the storage tank, emergency repair workers can step on the floating pedal and move to the vicinity of the storage tank for inspection, thereby reducing the chance of contact with leaked sodium cyanide and being safer.

[0017] Optionally, leakage detection probes that penetrate the soil horizontally are evenly distributed at intervals along the circumference of the inner circumferential wall of the anti-pollution side plate.

[0018] By arranging a leak detection probe on the inner wall of the anti-pollution side panel, the leak detection probe can be inserted into the soil. Once a leak occurs, the detection probe can quickly detect the presence of sodium cyanide in the soil, and the transfer of liquid sodium cyanide can be quickly started, which is more convenient and faster.

[0019] Optionally, a connecting sleeve is coaxially provided in the middle of the storage tank and the transfer tank near one end of each other, and a plurality of the lower leakage pipes are evenly distributed circumferentially in the connecting sleeve. An operating rod is vertically rotated in the middle of the connecting sleeve, and the upper and lower ends of the operating rod are respectively inserted into the storage tank and the transfer tank, and the sealing plates are evenly distributed circumferentially at the upper and lower ends of the operating rod and seal or open the lower leakage pipes as the operating rod rotates.

[0020] By setting a connecting sleeve between the storage tank and the transfer tank to protect multiple lower leakage pipes, the lower leakage pipes are evenly distributed between the connecting sleeves in the circumferential direction. Since the openings at both ends of the multiple lower leakage pipes are opened and closed synchronously, an operating rod is rotatably set in the middle of the multiple lower leakage pipes, so that the sealing plates are evenly distributed axially at both ends of the operating rod. When the operating rod is rotated, all the sealing plates can be driven to rotate to realize the opening and closing of the lower leakage pipes, which is more convenient.

[0021] Optionally, a plurality of drive motors are provided inside the connecting sleeve, a drive gear is provided on the output shaft of the drive motor, and a long gear meshing with the drive gear is coaxially provided in the middle of the operating rod.

[0022] The drive gears are controlled to rotate synchronously by multiple sets of drive motors to control the rotation of the long gear, thereby realizing the rotation of the operating lever. This solution makes the rotation of the operating lever more controllable and more convenient.

[0023] Optionally, the sealing plate is rotatably connected to the top of the vent pipe via a torsion spring, and a sealing adhesive layer is provided on one end face of the sealing plate close to the vent pipe, the sealing layer being in contact with the upper opening of the vent pipe.

[0024] By rotating the sealing plate to connect it to the top of the vent pipe through a torsion spring, and providing a sealing rubber layer on one end face of the sealing plate, when sodium cyanide is normally stored in the storage tank, the sealing plate seals the top opening of the vent pipe under the action of the torsion spring and the sealing rubber layer, thereby preventing the sodium cyanide from volatilizing into the transfer tank. At the same time, when the sodium cyanide is transferred, the liquid sodium cyanide will enter the transfer tank along the lower leakage pipe. At this time, the internal pressure of the transfer tank increases, thereby squeezing the air to push open the sealing plate, thereby allowing the sodium cyanide to leak smoothly, which is more convenient.

[0025] (3) Beneficial effects

[0026] The beneficial effects of the utility model are as follows: when the liquid sodium cyanide finished product storage tank of the utility model is used to store the liquid sodium cyanide finished product, the sodium cyanide is directly injected into the storage tank for storage; once the storage tank leaks, the sealing plates at both ends of the lower leakage pipe are directly opened, so that the sodium cyanide in the storage tank leaks directly into the transfer tank along the lower leakage pipe; when the sealing plates are opened, the air pressure between the storage tank and the transfer tank can be balanced, so that the sodium cyanide can enter the transfer tank more quickly; after the transfer of sodium cyanide is completed, the two ends of the lower leakage pipe can be closed by the sealing plates; at this time, relevant personnel approach the liquid sodium cyanide finished product storage tank for maintenance; this solution can stop the leakage of the liquid sodium cyanide finished product in time, avoid continuous leakage, and thus improve the safety of the repair personnel.

DETAILED DESCRIPTION

[0030] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0031] The liquid sodium cyanide finished product storage tank proposed in the embodiment of the present invention has the following characteristics: when storing liquid sodium cyanide finished product through the liquid sodium cyanide finished product storage tank, sodium cyanide is directly injected into the storage tank for storage; once the storage tank leaks, the sealing plates at both ends of the lower leakage pipe are directly opened, so that the sodium cyanide in the storage tank leaks directly into the transfer tank along the lower leakage pipe; when the sealing plates are opened, the air pressure between the storage tank and the transfer tank can be balanced, so that the sodium cyanide can enter the transfer tank more quickly; after the transfer of sodium cyanide is completed, the two ends of the lower leakage pipe can be closed by the sealing plates; at this time, relevant personnel approach the liquid sodium cyanide finished product storage tank for maintenance; this solution can stop the leakage of the liquid sodium cyanide finished product in time, avoid continuous leakage, and thus improve the safety of the repair personnel.

[0032] To better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0033] Reference Figure 1 A liquid sodium cyanide finished product storage tank includes a transfer tank 1 buried underground and a storage tank 2 fixed on the ground and located directly above the transfer tank 1, and the storage tank 2 is connected to the transfer tank 1.

[0034] The top of the transfer tank 1 is integrally provided with a plurality of lower leakage pipes 3 connected to the bottom wall inside the storage tank 2, and the top of the transfer tank 1 is integrally provided with a plurality of ventilation pipes 4 connected to the top wall inside the storage tank 2. The storage tank 2 and the transfer tank 1 are respectively provided with sealing plates 5 at the upper and lower ends of the lower leakage pipe 3 for sealing the upper and lower openings of the lower leakage pipe 3. The sealing plates 5 open the upper and lower ends of the lower leakage pipe 3 when a leak occurs in the storage tank 2. The ventilation pipe 4 is provided with a sealing plate 6 for sealing the top opening. The sealing plate 6 opens the ventilation pipe 4 when a leak occurs in the storage tank 2. When storing liquid sodium cyanide finished product through the liquid sodium cyanide finished product storage tank, sodium cyanide is directly injected into the storage tank 2 for storage. Once the storage tank 2 leaks, the sealing plates 5 at both ends of the lower leakage pipe 3 are directly opened, so that the sodium cyanide in the storage tank 2 leaks directly into the transfer tank 1 along the lower leakage pipe 3. When the sealing plate 6 is opened, the air pressure between the storage tank 2 and the transfer tank 1 can be balanced, so that the sodium cyanide can enter the transfer tank 1 more quickly. After the transfer of sodium cyanide is completed, the two ends of the lower leakage pipe 3 can be closed by the sealing plates 5.

[0035] A connecting sleeve 7 is coaxially welded in the middle of the storage tank 2 and the transfer tank 1 near one end. A plurality of lower leakage pipes 3 are evenly spaced circumferentially in the connecting sleeve 7. An operating rod 71 is provided in the middle of the connecting sleeve 7 for vertical rotation. The upper and lower ends of the operating rod 71 are sealed and penetrate the storage tank 2 and the transfer tank 1 respectively. The sealing plates 5 are evenly spaced circumferentially at the upper and lower ends of the operating rod 71 and seal or open the lower leakage pipe 3 as the operating rod 71 rotates. Multiple groups of drive motors 72 are fixed to the inside of the connecting sleeve 7 by bolts. A drive gear 73 is keyed to the output shaft of the drive motor 72. A long gear 711 meshing with the drive gear 73 is coaxially welded in the middle of the operating rod 71. The drive gear 73 is controlled to rotate synchronously by multiple groups of drive motors 72 to control the rotation of the long gear 711, thereby realizing the rotation of the operating rod 71, and finally driving all the sealing plates 5 to rotate, so as to realize the opening and closing of the lower leakage pipe 3, which is more convenient.

[0036] Sealing plate 6 is rotatably connected to the top of vent tube 4 via a torsion spring. Adhesive layer 61 is bonded to one end of sealing plate 6, which abuts the upper opening of vent tube 4. When storage tank 2 is storing sodium cyanide normally, sealing plate 6, acting in conjunction with the torsion spring and sealant layer 61, seals the top opening of vent tube 4, preventing sodium cyanide from evaporating into transfer tank 1. Simultaneously, when sodium cyanide is being transferred, liquid sodium cyanide flows along lower leakage pipe 3 into transfer tank 1. The increased pressure inside transfer tank 1 squeezes air, pushing open sealing plate 6 and allowing the sodium cyanide to escape.

[0037] A contamination-resistant bottom plate 8 is welded horizontally and coaxially to the lower end of transfer tank 1. Contamination-resistant side plates 9, partially extending to the ground, are integrally mounted vertically on the outer edges of bottom plate 8. Soil is filled between bottom plate 8 and the ends of the side plates. If storage tank 2 leaks, the leaked liquid sodium cyanide will flow between bottom plate 8 and side plates 9, reducing the risk of further diffusion. Simultaneously, the soil between bottom plate 8 and side plates 9 allows the leaked liquid sodium cyanide to dissolve directly in the soil, reducing the risk of widespread volatilization and enhancing safety. Furthermore, the soil provides support for storage tank 2.

[0038] A slide rail 91 is coaxially mounted on the upper end of the anti-pollution side panel 9. A surveillance camera 92 is slidably mounted on the slide rail 91, with the camera end of the surveillance camera 92 continuously aligned with the storage tank 2. The surveillance camera 92 can slide along the length of the slide rail 91, performing a circular motion around the storage tank 2. During this circular motion, the camera end of the surveillance camera 92 continuously aligned with the storage tank 2, thereby providing real-time, all-round video monitoring of the storage tank 2.

[0039] Floating steps 93, evenly spaced and welded to the upper end of the anti-pollution side panels 9 near the inner circumference of the storage tank 2, are horizontally connected to the side of the storage tank 2. These steps are located above the soil filling between the anti-pollution base plate 8 and the anti-pollution side panels 9. In the event of a leak in the storage tank 2, repair personnel can step on the floating steps 93 to move closer to the storage tank 2 for inspection, thereby reducing the chance of contact with leaked sodium cyanide.

[0040] Leak detection probes 94 that penetrate the soil horizontally are evenly spaced around the inner wall of the anti-pollution side plate 9. Once a leak occurs, the leak detection probes 94 can quickly detect the presence of sodium cyanide in the soil, and the transfer of liquid sodium cyanide can be quickly started, which is more convenient and faster.
