Description

Technical Field

[0001] This invention relates to the field of chemical raw material transportation technology, and in particular to a leak-proof chemical raw material transportation tank. Background Technology

[0002] Chemical raw material transport tanks are containers specifically designed for transporting various chemical products, including liquids, gases, slurries, and certain powdered chemical raw materials. These tanks are typically made of durable, corrosion-resistant materials to accommodate the characteristics of various chemical raw materials. The transport tanks are equipped with baffles inside to reduce liquid surging, and the top of the transport tank also has a manhole cover to facilitate maintenance personnel access to the interior of the tank.

[0003] Due to the highly corrosive nature of some chemical raw materials, the metal sealing ring between the transport tank and the manhole cover is prone to aging and damage due to prolonged corrosion. During sudden braking while transporting liquid chemicals, the liquid chemicals located at the rear of the tank surge towards the front, creating a strong wave inside the tank. This increases the amount of chemical material between adjacent baffles at the front of the tank, compressing the space between the baffles and increasing pressure on the manhole cover. Simultaneously, the liquid chemicals, blocked and guided upwards by the baffles, impact the manhole cover. Corrosive chemicals seep into the gap between the manhole cover and the transport tank, accelerating the corrosion and aging of the metal sealing ring. Corrosive chemicals and chemical gases can easily leak from the corroded and aged metal sealing ring between the manhole cover and the transport tank to the outside, posing a safety hazard. Summary of the Invention

[0004] To overcome the drawback of corrosive chemical raw materials inside the transport tank impacting the manhole cover due to the inertia of sudden braking, which can easily lead to leakage of corroded and aged metal seals between the manhole cover and the transport tank, posing a safety hazard, this invention provides a leak-proof chemical raw material transport tank.

[0005] The technical solution is as follows: A leak-proof chemical raw material transport tank, comprising a transport tank, manhole covers, and breather valves; the transport tank is provided with several manholes; each manhole is rotatably connected to a manhole cover; each manhole cover is provided with a breather valve for balancing the air pressure inside the transport tank with the outside air pressure; it also includes driving components, transverse baffles, longitudinal baffles, and guiding components; a cavity is opened at the front of the transport tank; several driving components are arranged inside the cavity; several transverse baffles for reducing the surging waves of chemical raw materials are slidably connected inside the transport tank; each transverse baffle is U-shaped; the telescopic ends of two opposing driving components on each side are connected to a transverse baffle. The system includes: fixed baffles; several fixed rods inside the transport tank; several longitudinal baffles rotatably connected to all fixed rods to reduce the surge of chemical raw materials; each longitudinal baffle has an opening; each longitudinal baffle has a through hole; the through holes on adjacent longitudinal baffles are staggered vertically; each longitudinal baffle has several clearance slots; each transverse baffle has several clearance sections; each transverse baffle passes through all clearance slots; each clearance section is located in its corresponding clearance slot; and each longitudinal baffle has a guiding component for guiding the chemical raw materials.

[0006] Furthermore, the guiding assembly includes guiding plates; each longitudinal wave deflector has several guiding plates fixed to its rear side for guiding chemical raw materials.

[0007] Furthermore, each guide plate is tilted towards the lower rear side of the longitudinal wave deflector.

[0008] Furthermore, each guide plate is provided with several guide parts; all guide parts on each guide plate are arranged to be inclined towards the center of the guide plate.

[0009] Furthermore, the guiding assembly also includes deflectors; several deflectors for guiding chemical raw materials are fixed to the rear side of each longitudinal wave deflector; all deflectors on each longitudinal wave deflector are distributed on the left and right sides of all guide plates on each longitudinal wave deflector.

[0010] Furthermore, each pair of corresponding guide vanes on the left and right are designed in a figure-eight shape.

[0011] Furthermore, it also includes reinforcing rings; each longitudinal baffle is fixed to the outside of a reinforcing ring to enhance the support effect of the longitudinal baffle on the transport tank; the outside of each reinforcing ring is in contact with the inner wall of the transport tank.

[0012] Furthermore, the contact surface between each reinforcing ring and the inner wall of the transport tank is designed as a convex arc surface.

[0013] Furthermore, it also includes reinforcing ribs; each longitudinal baffle has several reinforcing ribs fixed to its front side to enhance the support effect of the longitudinal baffle on the transport tank, and the reinforcing ribs on each longitudinal baffle are fixed to the inner ring surface of the corresponding reinforcing ring.

[0014] Furthermore, it also includes baffles; several baffles for blocking chemical raw materials are fixed to the upper side of the transverse baffle located above; the baffles are made of corrosion-resistant material; each baffle is located in front of the corresponding longitudinal baffle; none of the baffles are in contact with the inner wall of the transport tank.

[0015] The beneficial effects of the present invention are as follows: The present invention guides the chemical raw materials to the lower part of the longitudinal baffle plate by tilting the baffle plate, preventing the wave surge caused by the chemical raw materials due to sudden braking from impacting the area below the orifice cover, and avoiding leakage of chemical raw materials and chemical gases from the metal sealing ring between the orifice cover and the transport tank that has been corroded and aged to the outside.

[0016] By using guide plates and deflectors that slope downwards towards the bottom of the transport tank, the chemical raw materials surging upwards towards the top of the transport tank are guided backwards, so that they counteract the chemical raw materials surging towards the front of the transport tank, which helps to reduce wave surges inside the transport tank.

[0017] By reinforcing the inner wall of the transport tank with reinforcing rings and ribs, the transport tank is reinforced to prevent the tank wall from denting and deforming due to low air pressure, thus avoiding structural damage and reduced strength, and reducing the risk of transporting chemical raw materials in the subsequent transport tank.

[0018] By using baffles to block the upward splashing of chemical materials, the amount of chemical materials splashed onto the orifice cover and the bottom of the breather valve is reduced, thus weakening the corrosive effect of the chemical materials on the orifice cover and the breather valve and helping to extend the service life of the orifice cover and the breather valve.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] like Figures 1-7 As shown, a leak-proof chemical raw material transport tank includes a transport tank 1, a manhole cover 2, and a breather valve 3; the transport tank 1 is provided with two manholes 1001; a manhole cover 2 is rotatably connected to each manhole 1001; and a breather valve 3 is provided on each manhole cover 2.

[0030] It also includes a drive unit 4, a transverse baffle 5, a longitudinal baffle 6, and a guide assembly; a cavity 1003 is provided at the front of the transport tank 1; several drive units 4, each consisting of four units arranged in a rectangular shape, are installed inside the cavity 1003; the drive units 4 are electric push rods; two transverse baffles 5, symmetrically arranged vertically, are slidably connected inside the transport tank 1; each transverse baffle 5 is U-shaped; the telescopic ends of two opposing drive units 4 on each side are fixedly connected to one transverse baffle 5; two symmetrically arranged fixing rods 1002 are installed inside the transport tank 1; three horizontally arranged rods are rotatably connected to all fixing rods 1002. The wave deflectors 6 are arranged in a row; each longitudinal wave deflector 6 has an opening 6001; each longitudinal wave deflector 6 has a through hole 6002; the through holes 6002 on two adjacent longitudinal wave deflectors 6 are staggered vertically; each longitudinal wave deflector 6 has four rectangularly distributed clearance slots 6003; each transverse wave deflector 5 has several clearance parts 5001; each transverse wave deflector 5 passes through all clearance slots 6003; each clearance part 5001 is located in the corresponding clearance slot 6003; each longitudinal wave deflector 6 has a guide component.

[0031] The guiding assembly includes a guide plate 101; several guide plates 101 arranged vertically are fixed to the rear side of each longitudinal wave deflector 6.

[0032] Furthermore, to prevent chemical raw materials from remaining on the guide plates 101 when extracting chemical raw materials from the transport tank 1, each guide plate 101 is inclined towards the lower rear side of the longitudinal baffle plate 6.

[0033] Each guide plate 101 is provided with a plurality of guide parts 10101; all guide parts 10101 on each guide plate 101 are arranged to be inclined toward the center of the guide plate 101.

[0034] The guiding assembly also includes a deflector plate 102; several deflector plates 102 that are symmetrically arranged on the left and right sides are fixed to the rear side of each longitudinal wave deflector plate 6; all the deflector plates 102 on each longitudinal wave deflector plate 6 are distributed on the left and right sides of all the guide plates 101 on each longitudinal wave deflector plate 6.

[0035] Furthermore, when extracting chemical raw materials from transport tank 1, in order to enhance the guiding effect on the chemical raw materials on the longitudinal baffle plate 6, each pair of corresponding guide plates 102 on the left and right are set in a figure-eight shape.

[0036] It also includes a reinforcing ring 7; a reinforcing ring 7 is fixed to the outer side of each longitudinal baffle 6; the outer side of each reinforcing ring 7 is attached to the inner wall of the transport tank 1.

[0037] Furthermore, to prevent the reinforcing ring 7 from rubbing against the inner wall of the transport tank 1, the contact surface between each reinforcing ring 7 and the inner wall of the transport tank 1 is designed as a convex arc surface.

[0038] It also includes reinforcing ribs 8; each longitudinal wave deflector 6 has several reinforcing ribs 8 fixedly connected to its front side, and each reinforcing rib 8 on the longitudinal wave deflector 6 is fixedly connected to the inner ring surface of the corresponding reinforcing ring 7.

[0039] In the transportation of liquid chemical raw materials, this invention uses a transverse baffle 5 to tilt the longitudinal baffle 6, thus solving the problem of wave surges generated by the chemical raw materials in the transport tank 1 impacting the area below the orifice cover 2 during sudden braking of the transport vehicle. This increases the pressure on the orifice cover 2, causing chemical gases in the transport tank 1 to leak from the seal of the orifice cover 2 to the outside. The specific process is as follows:

[0040] The metal sealing ring between the manhole cover 2 and the transport tank 1 is prone to aging and damage due to prolonged corrosion from chemical raw materials. Before transporting chemical raw materials using the transport tank 1, the drive component 4 located at the upper part of the transport tank 1 within the control chamber 1003 extends, causing the upper transverse baffle 5 to move backward. Simultaneously, the drive component 4 located at the lower part of the transport tank 1 within the control chamber 1003 retracts, causing the lower transverse baffle 5 to move forward. Through the staggered movement of the two transverse baffles 5, the clearance part 5001 engages with the clearance groove 6003, causing all longitudinal baffles 6 to rotate on the fixed rod 1002 until... Figure 6The tilted state shown in the figure causes the guide plate 101 and the flow guide plate 102 to tilt together toward the lower part of the transport tank 1. At this time, the upper and lower parts of the reinforcing ring 7 separate from the inner wall of the transport tank 1.

[0041] During the transportation of chemical raw materials, considering factors such as the thermal expansion of the chemical raw materials, a certain space is reserved inside the transport tank 1 to avoid overpressure. When the transport vehicle brakes suddenly, the chemical raw materials inside the transport tank 1 continue to surge forward due to inertia, generating forward momentum and forming a wave surge inside the transport tank 1. During this process, the surging chemical raw materials are blocked by the transverse baffle 5 and the longitudinal baffle 6, allowing the chemical raw materials to pass through the staggered through holes 6002 on all the longitudinal baffle 6, which disperses the impact force generated by the surge of chemical raw materials, which helps to reduce the wave surge and thus reduce the impact force of the chemical raw materials on the inner wall of the transport tank 1, improving the protection effect of the transport tank 1.

[0042] When the chemical raw materials in transport tank 1 surge upwards due to inertia, the longitudinal baffle 6, which provides space at the top of the tank, blocks and deflects the chemical raw materials, causing them to rush upwards and impact the lower side of the orifice cover 2 and the breather valve 3. During this process, the longitudinal baffle 6, which slopes forward at the bottom, guides the chemical raw materials downwards, providing secondary deflection to the upward-rushing chemical raw materials and reducing the amount of chemical raw materials impacting the lower side of the orifice cover 2 and the breather valve 3. Simultaneously, the guide plate 101 and the flow deflector 102, which slope downwards towards the bottom of the transport tank 1, further contribute to this process. The upward-flowing chemical raw materials in the upper part of the transport tank 1 are guided backward to counteract the upward-flowing chemical raw materials in the front of the transport tank 1. This further disperses the impact force generated when the chemical raw materials flow forward, reducing the wave surge inside the transport tank 1. It also prevents the wave surge caused by the chemical raw materials due to sudden braking from impacting the area below the orifice cover 2, avoiding increased pressure on the orifice cover 2. Consequently, it prevents the chemical raw materials and chemical gases from leaking to the outside from the corroded and aged metal sealing ring between the orifice cover 2 and the transport tank 1, thus improving the sealing effect of the transport tank 1 when transporting chemical raw materials.

[0043] When the chemical raw materials arrive at their destination and need to be extracted from transport tank 1, the drive component 4 located at the upper part of transport tank 1 is retracted, causing the upper transverse baffle 5 to move forward. Simultaneously, the drive component 4 located at the lower part of transport tank 1 is extended, causing the lower transverse baffle 5 to move backward. Through the staggered movement of the two transverse baffles 5, the inclined longitudinal baffle 6 is rotated on the fixed rod 1002 to a vertical position, allowing the reinforcing ring 7 to re-fit fully against the inner wall of transport tank 1, providing support for transport tank 1 and simultaneously ensuring the smooth flow of chemical raw materials within transport tank 1. The chemical raw materials are extracted through the port 6001. During this process, the liquid level of the chemical raw materials in the transport tank 1 drops, and the chemical raw materials remaining on the guide plate 101 converge towards the center of the guide plate 101 through the guide part 10101, which helps to accelerate the dripping speed of the chemical raw materials on the guide plate 101. At the same time, the chemical raw materials on the longitudinal baffle plate 6 are guided to the edge of the longitudinal baffle plate 6 by the figure-eight shaped baffle plate 102, so that the chemical raw materials converge and increase the downward flow speed of the chemical raw materials on the longitudinal baffle plate 6, which helps to reduce the residue of chemical raw materials in the transport tank 1.

[0044] When chemical raw materials are rapidly extracted from transport tank 1, the breather valve 3, due to prolonged use and corrosion from the chemical raw materials, becomes less effective at regulating the air pressure inside transport tank 1. As the gas inside transport tank 1 cannot be replenished in time, the internal volume of transport tank 1 increases, creating negative pressure. The reinforcing ring 7 is reinforced by the reinforcing rib 8, enhancing its support effect on transport tank 1. The reinforcing ring 7 and the reinforcing rib 8 together support the inner wall of transport tank 1, reinforcing it and preventing the tank wall from collapsing and deforming due to low air pressure. This avoids structural damage and reduced strength of transport tank 1, lowering the risk of subsequent transport of chemical raw materials using transport tank 1.

[0045] After the chemical raw materials in transport tank 1 have been discharged and the tank has been steam-cleaned, maintenance personnel need to enter the tank for inspection. To check the condition of the tank, a ladder needs to be suspended from manhole 1001 before entering. During this process, the ladder's stress point is at the top, causing it to sway and pose a safety hazard. Furthermore, the weight of the maintenance personnel, acting through the ladder, puts pressure on the upper side of manhole 1001. Over time, this can cause localized indentations on the upper side of manhole 1001, resulting in gaps between the manhole cover 2 and the upper side of manhole 1001 when closed. This allows the chemical raw materials in transport tank 1 to easily leak to the outside. To address these issues, the specific process is as follows:

[0046] When maintenance personnel need to enter the transport tank 1 for repairs, the drive component 4 located at the upper part of the transport tank 1 is continuously retracted, causing the upper transverse baffle 5 to move forward continuously. Simultaneously, the drive component 4 located at the lower part of the transport tank 1 is continuously extended, causing the lower transverse baffle 5 to move backward continuously. Through the staggered movement of the two transverse baffles 5, the vertical longitudinal baffle 6 is rotated on the fixed rod 1002 until... Figure 7 In the tilted state shown, when maintenance personnel enter the transport tank 1 through the manhole 1001, they can enter the transport tank 1 via the steps formed by the guide plate 101 without the need for a ladder, thus avoiding pressure on the upper side of the manhole 1001. At the same time, the guide part 10101 increases the friction between the maintenance personnel and the guide plate 101 when they step on it, preventing the maintenance personnel from slipping and improving the protection effect for the maintenance personnel.

[0047] Example 2

[0048] Based on Example 1, such as Figures 2-4 and Figure 6 As shown, it also includes baffles 201; two baffles 201 are fixed to the upper side of the transverse baffle 5 located above; the baffles 201 are made of corrosion-resistant material; each baffle 201 is located in front of the corresponding longitudinal baffle 6; none of the baffles 201 are in contact with the inner wall of the transport tank 1.

[0049] When the transverse baffle 5 on the upper part of the transport tank 1 moves backward, the transverse baffle 5 drives the baffle 201 to move backward together to below the manhole 1001, blocking the area below the manhole 1001. When the chemical raw materials in the transport tank 1 form waves due to inertia, the baffle 201 blocks the chemical raw materials that surge upward and splash, reducing the amount of chemical raw materials splashed to the lower side of the manhole cover 2 and the breather valve 3, weakening the corrosive effect of the chemical raw materials on the manhole cover 2 and the breather valve 3, and helping to extend the service life of the manhole cover 2 and the breather valve 3.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
