Description

Technical Field

[0001] The embodiments of this utility model relate to the technical field of corrosion-resistant tanks, specifically, to a corrosion-resistant tank that facilitates material discharge. Background Technology

[0002] Corrosion-resistant tanks are core equipment in the chemical, food, and pharmaceutical industries for storing corrosive materials such as acids, alkalis, and solvents. Their smooth discharge and operational safety directly impact production efficiency and environmental safety. As industries increasingly demand safer and more efficient production processes, the shortcomings of traditional corrosion-resistant tanks are becoming more apparent: existing tanks focus on the tank's own corrosion resistance, lacking targeted venting and protective designs. This results in internal gases not being able to escape promptly during discharge, and insufficient tank protection, leading to both poor discharge and safety risks.

[0003] The drawbacks of traditional corrosion-resistant tanks are particularly prominent: during the discharge process, the flow of materials inside the tank causes gas to accumulate in the enclosed space, and the increased pressure leads to fluctuating discharge flow rates, and even material splashing. This not only affects the accuracy of metering, but may also cause leakage of corrosive materials; the inability of gas to escape can also easily form gas locks, resulting in increased residual material after discharge, wasting raw materials and increasing the difficulty of cleaning; in terms of protection, the tank body mostly relies on anti-corrosion coatings without external buffers or anti-collision structures. It is easily damaged after being subjected to external impacts or corrosion aging, which exacerbates the risk of leakage. At the same time, the discharge port has no protective design, and accidental contact can easily cause personal injury, which does not meet safety regulations.

[0004] Therefore, developing a corrosion-resistant tank that combines smooth gas discharge with protective functions and facilitates material discharge has become an urgent need to solve the pain points of traditional tanks. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this utility model provide a corrosion-resistant tank that facilitates material discharge, solving the technical problem that existing corrosion-resistant tanks focus on the corrosion resistance of the tank body itself, lack targeted exhaust and protection designs, and cannot discharge internal gas in a timely manner during material discharge.

[0006] According to one aspect, at least one embodiment of the present invention provides a corrosion-resistant tank for easy material discharge, comprising: The tank body, the discharge pipe, and the control valve are provided on the discharge pipe. Protective components, wherein the protective components are disposed on the exterior of the tank body; A feed ventilation assembly is disposed at the top of the tank body; The feeding and ventilation assembly includes a feeding pipe located at the top of the tank. A connecting pipe is provided on the outside of the feeding pipe. An electric telescopic rod is installed vertically upward on the outside of the feeding pipe. A sealing block is provided at the output end of the electric telescopic rod. The sealing block is vertically and sealingly inserted into the feeding pipe.

[0007] As a further technical solution, a ventilation pipe is provided on the top of the tank, a solenoid valve is installed on the ventilation pipe, a ventilation hood is horizontally fixedly connected to the upper end of the ventilation pipe, an adsorption and purification packing is inserted into the ventilation hood, and a compression pipe is fitted to the side end face of the ventilation hood.

[0008] According to another aspect, in at least one embodiment of the present invention, the protective component includes a plurality of protective plates, all of which are disposed on the outer wall of the tank, and a plurality of buffer springs are disposed on the outer wall of the tank, all of which are connected to the protective plates.

[0009] As a further technical solution, a buffer pad is connected between the protective plate and the outer wall of the tank. The buffer pad is made of a rubber material that can be filled with gas. All the protective plates are arc-shaped transition structures, and the curvature of the protective plate is the same as that of the outer wall of the tank.

[0010] As a further technical solution, a pressure gauge is installed on the top of the tank.

[0011] As a further technical solution, the bottom of the tank is provided with several support frames, all of which are L-shaped.

[0014] The beneficial effects of the embodiments of this utility model are as follows: This invention solves the problems of air resistance and gas leakage during discharge in traditional corrosion-resistant tanks by using a feeding and ventilation assembly. An electric telescopic rod drives a sealing block to flexibly open and close the feeding pipe, while double sealing rings ensure sealing performance and prevent leakage of corrosive materials. Before discharge, a solenoid valve is opened, allowing the ventilation pipe to quickly balance the air pressure inside the tank, preventing air resistance that could lead to poor discharge, material splashing, or metering errors. A pressure gauge monitors pressure changes in real time, ensuring safe and controllable operation.

[0015] The adsorption and purification packing inside the ventilation hood can efficiently adsorb harmful gases discharged from the tank. Tightening the pipes ensures the packing is securely installed, preventing environmental pollution and achieving environmentally friendly gas emissions. The entire assembly integrates feed control, pressure balancing, and gas purification, ensuring smooth discharge, reducing material residue and waste, and solving the safety and environmental hazards of corrosive gas leakage. It is suitable for the special needs of storing various corrosive materials, improving the safety and environmental friendliness of the production process. Attached Figure Description

[0024] like Figures 1-5 As shown, it illustrates a corrosion-resistant tank for easy material discharge according to an embodiment of the present invention, comprising: Tank 1, discharge pipe 2 and control valve 3, wherein the discharge pipe 2 is connected to the bottom of the tank 1 and the control valve 3 is installed on the discharge pipe 2; Protective component 5, wherein the protective component 5 is disposed outside the tank body 1; Feeding and ventilation assembly 4 is disposed on the top of the tank body 1; The feeding and ventilation assembly 4 includes a feeding pipe 4-1, which is located at the top of the tank body 1. A connecting pipe 4-2 is provided on the outside of the feeding pipe 4-1. An electric telescopic rod 4-3 is vertically installed on the outside of the feeding pipe 4-1. A sealing block 4-4 is provided at the output end of the electric telescopic rod 4-3. The sealing block 4-4 is vertically and sealingly inserted into the feeding pipe 4-1. A ventilation pipe 4-5 is provided at the top of the tank body 1. A solenoid valve 4-6 is installed on the ventilation pipe 4-5. A ventilation hood 4-7 is horizontally and fixedly connected to the upper end of the ventilation pipe 4-5. An adsorption and purification packing 4-8 is inserted into the ventilation hood 4-7. A compression pipe 4-9 is fitted onto the side end face of the ventilation hood 4-7.

[0025] In some examples, in order to achieve efficient ventilation and gas purification during the feeding and discharging process of the corrosion-resistant tank and solve the problems of pressure imbalance and harmful gas leakage when liquid is fed into and out of the traditional tank 1, a feeding ventilation component 4 was designed. This component includes a tank 1 made of corrosion-resistant alloy material welded together, with an anti-corrosion coating sprayed on the inner wall to adapt to the storage of various corrosive materials, a bottom discharge pipe 2 welded to the tank 1, and a control valve 3 fixed to the discharge pipe 2 through a flange to provide precise control for discharge, thus forming a stable storage and discharge foundation.

[0026] The feed pipe 4-1 at the top of tank 1 is rigidly connected via a flange to ensure sealing performance and prevent material leakage. The connecting pipe 4-2 on the outside of the feed pipe 4-1 is welded to the feed pipe 4-1 for connecting external feeding equipment to achieve directional feeding. The electric telescopic rod 4-3 is vertically fixed to the outside of the feed pipe 4-1 via a bracket, and the output end is rigidly connected to the sealing block 4-4 via bolts. The sealing block 4-4 is made of corrosion-resistant rubber and fits precisely with the inner wall of the feed pipe 4-1, allowing for vertical sealing and insertion to open and close the feed port. The ventilation pipe 4-5 at the top of the tank 1 is welded to the tank 1. The solenoid valve 4-6 is fixed to the ventilation pipe 4-5 by threads to realize the automatic control of the ventilation channel. The ventilation hood 4-7 at the upper end of the ventilation pipe 4-5 is fixed horizontally by bolts. An installation cavity is reserved inside the hood. The adsorption and purification packing 4-8 is inserted into the cavity. The packing uses a high-efficiency adsorption material to meet the gas purification requirements. The compression pipe 4-9 on the side end face of the ventilation hood 4-7 is connected by a threaded sleeve to compress the packing to prevent displacement and to discharge the purified gas.

[0027] During feeding, the electric telescopic rod 4-3 drives the sealing block 4-4 to rise and open the feed port. The solenoid valve 4-6 opens simultaneously. The gas in the tank is purified by the packing in the ventilation hood 4-7 and then discharged. After feeding is completed, the sealing block 4-4 closes and the solenoid valve 4-6 closes to ensure the tank is sealed and the gas is discharged in an environmentally friendly manner. During discharge, the solenoid valve 4-6 opens to balance the air pressure and ensure smooth discharge.

[0028] like Figures 1-5 As shown in the figure, the protective component 5 in this embodiment includes a plurality of protective plates 5-1, all of which are disposed on the outer wall of the tank body 1. A plurality of buffer springs 5-2 are disposed on the outer wall of the tank body 1, and all of the buffer springs 5-2 are connected to the protective plates 5-1. A buffer pad 5-3 is connected between the protective plates 5-1 and the outer wall of the tank body 1. The buffer pad 5-3 is made of a rubber material that can be filled with gas. All of the protective plates 5-1 are arc-shaped transition structures, and the arc of the protective plates 5-1 is the same as that of the outer wall of the tank body 1.

[0029] In some examples, in order to achieve reliable protection of the outer wall of the anti-corrosion tank and solve the problem of poor impact resistance and easy damage to the tank 1 of the traditional protective structure, a protective component 5 was designed. This component includes the tank 1 as the core storage component. The outer wall needs to resist external collisions and friction. The protective plate 5-1 is made of high-strength wear-resistant steel plate. The arc transition structure is precisely matched with the curvature of the outer wall of the tank 1 to ensure a tight fit and not affect the heat dissipation of the tank 1.

[0030] Several spring seats are welded to the outer wall of the tank body 1. One end of the buffer spring 5-2 is welded to the spring seat, and the other end is connected to the inner side of the protective plate 5-1 by bolts. The springs are evenly distributed to ensure balanced force. The buffer pad 5-3 between the protective plate 5-1 and the outer wall of the tank body 1 is made of gas-fillable rubber material and is attached to the protective plate 5-1 and the outer wall of the tank body 1 by strong adhesive, forming a double buffer structure of spring and air cushion.

[0031] When tank 1 is subjected to an external impact, the impact force first acts on the arc-shaped protective plate 5-1. The protective plate 5-1 disperses the force to each buffer spring 5-2. The springs compress and absorb part of the energy, while the gas inside the buffer pad 5-3 is compressed and deformed, further buffering the remaining impact force and preventing the impact force from acting directly on tank 1. The arc-shaped structure can convert concentrated impact force into dispersed force, the wear-resistant steel plate increases the service life of the protective plate 5-1, and the double buffer structure greatly improves the impact resistance, effectively protecting tank 1 and the inner anti-corrosion coating from damage.

[0032] For example, such as Figure 1 As shown, a pressure gauge 6 is installed on the top of the tank 1.

[0033] In some examples, the pressure gauge 6 on top of tank 1 is connected via a threaded seal. The gauge body is made of corrosion-resistant stainless steel, and the dial is equipped with anti-fog glass to adapt to humid environments. Pressure gauge 6 is connected to the inside of the tank to monitor the tank pressure in real time during feeding, discharging, and storage. It is also linked to the solenoid valve 4-6 of the ventilation pipe 4-5. When the pressure exceeds the limit, the ventilation is automatically activated to reduce the pressure and ensure the safe operation of tank 1. The gauge needle has a damping design to avoid inaccurate readings caused by pressure fluctuations.

[0034] For example, such as Figure 1 As shown, the bottom of the tank 1 is provided with several support frames 7, all of which are L-shaped.

[0035] In some examples, the L-shaped support frame 7 at the bottom of the tank 1 is formed by welding angle steel and is fully welded to the bottom of the tank 1. The bottom of the support is welded with an anti-slip pad and has mounting holes. The L-shaped structure increases the contact area with the ground, distributing the weight of the tank 1. The anti-slip pad enhances ground adhesion. The mounting holes can be fixed to the ground with expansion bolts to prevent the tank 1 from tipping over. The surface of the support is treated with anti-corrosion coating to suit outdoor use.

[0036] For example, such as Figure 5 As shown, a pair of sealing rings 8 are provided around the outer surface of the sealing block 4-4.

[0037] In some examples, a pair of sealing rings 8 on the outer surface of the sealing block 4-4 are made of oil- and corrosion-resistant fluororubber and are embedded in the pre-set annular grooves of the sealing block 4-4, fitting tightly against the inner wall of the feed pipe 4-1. The double sealing ring design enhances sealing redundancy and prevents material or gas leakage. The surface of the sealing rings 8 is smoothed to reduce friction with the inner wall of the pipe, and is compatible with the frequent lifting and lowering movements of the sealing block 4-4 driven by the electric telescopic rod 4-3.

[0038] For example, such as Figure 3 As shown, the buffer springs 5-2 are all connected to the edge of the protective plate 5-1.

[0039] In some examples, the buffer spring 5-2 is bolted to a spring seat on the edge of the protective plate 5-1, and is evenly distributed along the edge of the curved protective plate 5-1, with the spring axis perpendicular to the protective plate 5-1. The edge layout disperses the impact force along the edge of the protective plate 5-1, avoiding concentrated force that could cause deformation of the protective plate 5-1. Together with the central buffer pad 5-3, it forms a rigid edge buffer and a flexible central energy-absorbing structure, improving the overall impact resistance.

[0040] In actual use: the L-shaped support frame 7 securely installs the tank 1 in the preset position, ensuring the unobstructed placement of the discharge pipe 2, and the control valve 3 is initially in the closed state; the protective plate 5-1 on the outside of the tank 1 is tightly fitted to the outer wall of the tank 1 by the buffer spring 5-2 and the buffer pad 5-3, and the arc structure is precisely matched with the curvature of the tank 1 to form all-round protection; during feeding, the electric telescopic rod 4-3 is activated to drive the sealing block 4-4 to rise vertically, opening the feeding pipe 4-1, and connecting to the external feeding equipment through the external connecting pipe 4-2. At the same time, the solenoid valve 4-6 on the ventilation pipe 4-5 is opened, and the gas inside the tank is discharged after being purified by the adsorption and purification packing 4-8 in the ventilation hood 4-7. Pressure gauge 6 on top of body 1 monitors the pressure inside the tank in real time. After feeding is completed, electric telescopic rod 4-3 drives sealing block 4-4 to descend. Double sealing ring 8 on the outer surface ensures that feeding pipe 4-1 is tightly sealed. Solenoid valve 4-6 is closed. Before discharging, solenoid valve 4-6 is opened to balance the air pressure inside the tank to avoid air resistance. Then, control valve 3 is slowly opened. The material is discharged smoothly through discharge pipe 2 under gravity. During the discharge process, adsorption and purification packing 4-8 continuously purifies the discharged gas. After the discharge is completed, control valve 3 and solenoid valve 4-6 are closed. If maintenance is required, the compression pipe 4-9 of ventilation hood 4-7 can be removed to replace adsorption and purification packing 4-8, completing one material storage and discharge process.
