Description

Technical Field

[0001] This invention relates to the field of chemical product storage technology, and more specifically, to a chemical product storage device for chemical engineering. Background Technology

[0002] In the field of chemical engineering, the storage of chemical products is a critical link in the production, transportation, and use processes. Because chemical products are usually flammable, explosive, corrosive, toxic, or volatile, the design of their storage facilities must meet stringent requirements for safety, sealing, corrosion resistance, and environmental adaptability.

[0003] In related technologies, common chemical product storage devices mainly include storage tanks, containers, and drums, which are then stacked together for storage. However, for different chemical products, stacking them together can easily lead to cross-reactions. For example, nitric acid mixed with organic matter can easily explode, and sodium hypochlorite reacts with acids to produce toxic chlorine gas. For similar chemical products, stacking them together can easily cause aggregation effects. For instance, a large accumulation of drummed flammable liquids can form a high-concentration vapor cloud, which may trigger a flash explosion upon contact with static electricity, electrical sparks, or open flames. Even minor leaks during long-term storage can lead to the accumulation of toxic vapors, endangering the health of workers. Therefore, we propose a chemical product storage device for chemical engineering. Summary of the Invention

The components include: temperature sensors, gas sensors and liquid sensors. The temperature sensors are mainly used to monitor temperature changes in the corresponding storage chamber, and the gas sensors and liquid sensors are used to monitor leakage of chemical drums in the corresponding storage chamber.

[0008] As a further improvement of the present invention, the base is provided with multiple pairs of air supply holes, each pair of air supply holes corresponding to multiple storage cavities. Each pair of air supply holes is arranged vertically, and the two ends of each air supply hole are respectively connected to the first cavity and the corresponding storage cavity. The temperature regulation component includes: multiple sets of air supply components, each pair of air supply components corresponding to multiple storage cavities. Each air supply component includes: a main pipe and two auxiliary pipes. The main pipe is disposed in the first cavity, and one end of it is connected to the outside of the base. The two auxiliary pipes correspond to the two corresponding air supply holes, and the two ends of each auxiliary pipe are respectively connected to the main pipe and the corresponding air supply hole. A solenoid valve is provided on the auxiliary pipe.

[0009] As a further improvement of the present invention, the chemical product storage device further includes: a plurality of sliding seats, one end of each sliding seat being disposed within the cavity two, and the other end extending radially outward from the seat body to the outside of the seat body; the plurality of sliding seats correspond one-to-one with the plurality of bases, and the base slides on the corresponding sliding seat; the driving assembly includes: a second motor, a connecting seat, and a hydraulic cylinder; the second motor is fixedly connected to the bottom of the cavity two, and the axis of its output shaft is collinear with the axis of the seat body; the upper and lower sides of the connecting seat are fixedly connected to the output ends of the hydraulic cylinder and the output shaft of the second motor, respectively; the hydraulic cylinder extends and retracts in the horizontal direction; the motor drives the hydraulic cylinder to rotate through the connecting seat, so that the extension and retraction end of the hydraulic cylinder selectively engages with any of the bases.

[0010] As a further improvement of the present invention, the telescopic end of the hydraulic cylinder is fixedly connected to a push plate with an arc-shaped structure, and the push plate is coaxially arranged with the second motor; the base is provided with a limiting plate with an L-shaped structure facing downward on the side facing the second motor, the limiting plate includes: a horizontal part and a vertical part, the side of the horizontal part away from the base is fixedly connected to the vertical part, and a mating cavity is defined between the base, the horizontal part and the vertical part, and the push plate selectively passes through the mating cavity when rotating with the hydraulic cylinder.

[0012] As a further improvement of the present invention, the bottom of the base is provided with a plurality of pulleys, which are symmetrically arranged on both sides of the base in the direction of movement.

[0013] As a further improvement of the present invention, the sliding seat is provided with two limiting grooves, which are arranged on both sides of the moving direction of the base and their length direction is the same as the moving direction of the base. The pulleys on both sides correspond one-to-one with the limiting grooves on both sides, and the pulleys on each side are arranged in the corresponding limiting groove.

[0014] As a further improvement of the present invention, the top of the base is provided with a positioning groove for positioning the chemical drum.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention provides multiple storage cavities on the base, allowing different chemical drums to be stored separately. This reduces cross-reactions and aggregation effects caused by malfunctions of the chemical drums. By sealing the storage cavities with sealing components, the chemical drums can be effectively isolated from the external environment, thereby protecting them and improving their safety.

[0017] 2. This invention uses a drive component to move the base, which can selectively move chemical drums into and out of the storage chamber. When the safety monitoring component detects a malfunction in a chemical drum, the drive component can promptly push the chemical drum outside the base, increasing the distance between it and other chemical drums. This also dilutes the concentration of harmful gases and facilitates timely handling by operators. Attached Figure Description

[0031] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0032] like Figures 1-12 As shown, a chemical product storage device for chemical engineering includes: a cylindrical base 1, multiple bases 2, multiple sealing components 3, a temperature regulating component 4, and a drive component 5. The base 1 primarily serves as a support and mounting component, providing a carrier for supporting and mounting corresponding parts. The bases 2 primarily provide support and can be used to support chemical drums. The sealing components 3 are used to isolate and seal the chemical drums. The temperature regulating component 4 is used to regulate the ambient temperature of the chemical drums. The drive component 5 is mainly used to move the chemical drums via the bases 2. It should be noted that the chemical drums are containers filled with chemical products; this application uses a drum shape as an example.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the base 1 has multiple storage cavities 11 arranged in a ring around its axis. Vertically, the cross-sectional shape of each storage cavity 11 can be circular, and the axis of each storage cavity 11 is parallel to the axis of the base 1. That is, the axes of the multiple storage cavities 11 are located on the same circumference, which makes the distribution of the storage cavities 11 more uniform. One side of each storage cavity 11 has a feed inlet 12 that communicates with the outside. The feed inlet 12 mainly serves a connecting function, allowing chemical drums to enter or exit the storage cavity 11 through the feed inlet 12.

[0034] The base 1 has two cavities, 13 and 14, which primarily provide installation space. Cavity 1 can be positioned above Cavity 14, and its cross-sectional shape can be an inverted T-shape in the horizontal direction. A cover plate 16 is also provided on the top of the base 1 to seal Cavity 13. The upper and lower sides of the storage cavity 11 can communicate with Cavity 13 and Cavity 14 respectively. Cavity 14 has multiple openings circumferentially connected to the outside, each corresponding to a different base 2.

[0035] In addition, such as Figure 1 and Figure 7 As shown, the base 2 can be a cylindrical structure, mainly used to support the chemical drums. Multiple bases 2 correspond one-to-one with multiple storage chambers 11. The base 2 is slidably positioned under the corresponding storage chamber 11 to selectively guide the chemical drums into and out of the inlet 12. When the base 2 guides the chemical drum into the storage chamber 11, the axis of the base 2 can be collinear with the axis of the corresponding storage chamber 11. This allows the chemical drum to be positioned in the middle of the storage chamber 11, reducing contact between the chemical drum and the inner wall of the storage chamber 11, thus providing better storage and protection for the chemical drum.

[0036] In addition, such as Figure 1 , Figure 2 , Figure 4 and Figure 9 As shown, multiple sealing components 3 are mounted on the base 1 and correspond one-to-one with multiple storage cavities 11. Each sealing component 3 includes a motor 31, a top plate 32, and an arc-shaped sealing plate 33 concentrically arranged with respect to the storage cavity 11. The motor 31 can be located on the upper side inside the cavity 13, i.e., the side with the larger space. The motor 31 can be fixedly connected to the cover plate 16, and its output shaft axis can be vertical. The upper and lower sides of the top plate 32 are simultaneously connected to the output shaft of the motor 31 and the sealing plate 33. The motor 31 drives the corresponding sealing plate 33 to rotate around the axis of the corresponding storage cavity 11 via the top plate 32 to selectively seal the feed inlet 12. It should be noted that the central angle of the sealing plate 33 is greater than the central angle of the feed inlet 12, ensuring that the sealing plate 33 can completely seal the feed inlet 12. To improve sealing performance, the outer diameter of the sealing plate 33 can be equal to the diameter of the storage cavity 11.

[0037] In the initial state of use, the sealing plate 33 is located inside the storage cavity 11, and the feed inlet 12 is fully open. When the base 2 pulls the chemical drum into the storage cavity 11, the motor 31 is started. The motor 31 drives the top plate 32 to rotate, which in turn causes the sealing plate 33 to rotate around the axis of the corresponding storage cavity 11, thus sealing the feed inlet 12 and improving the safety of the stored chemical drum. When it is necessary to remove the chemical drum, the motor 31 is started again. The motor 31, through the top plate 32, drives the sealing plate 33 to rotate and disengage from the feed inlet 12, thereby releasing the seal on the chemical drum.

[0038] Furthermore, the top plate 32 can be a cylindrical structure with its axis collinear with the axis of the corresponding storage cavity 11, and the radius of the top plate 32 is the same as the radius of the storage cavity 11. This allows the top plate 32 to better seal the top of the storage cavity 11, thereby improving the sealing performance. Similarly, the base 2 can also be a cylindrical structure with its axis collinear with the axis of the corresponding storage cavity 11, and the radius of the base 2 is the same as the radius of the storage cavity 11. This allows the base 2 to better seal the bottom of the storage cavity 11 after it enters the storage cavity 11, thereby further improving the sealing performance.

[0039] As an optional embodiment, such as Figure 5 and Figure 6 As shown, an arc-shaped guide groove 17 is provided at the top of the storage cavity 11, and an arc-shaped guide plate 321 is provided around the top plate 32. The guide plate 321 is slidably connected within the guide groove 17. The sliding connection between the guide groove 17 and the guide plate 321 makes the rotation of the top plate 32 more stable.

[0040] In addition, such as Figure 1 , Figure 4 and Figure 5 As shown, the temperature regulating component 4 is installed in the cavity 13 and is used to supply air to the multiple storage cavities 11, thereby regulating the temperature inside the storage cavities 11, which is beneficial for protecting the chemical drums.

[0041] Specifically, the base 2 has multiple pairs of air supply holes 15 inside, each pair corresponding to a different storage cavity 11. Each pair of air supply holes 15 can be positioned vertically, and both ends of the air supply hole 15 are connected to the cavity 13 and the corresponding storage cavity 11, respectively. The air supply holes 15 primarily function to supply air.

[0042] Each storage cavity 11 corresponds to two air outlets 15, which are connected to the upper and lower sides of the storage cavity 11, respectively. When hot air needs to be supplied into the storage cavity 11, since hot air rises, air can be supplied from the lower air outlet 15 into the corresponding storage cavity 11, thereby making the temperature inside the storage cavity 11 more uniform. Similarly, when cold air needs to be supplied into the storage cavity 11, since cold air falls, air can be supplied from the upper air outlet 15 into the corresponding storage cavity 11, thereby making the temperature inside the storage cavity 11 more uniform. This makes it more flexible and convenient to use.

[0043] The temperature control component 4 includes multiple sets of air supply components 41, each corresponding to one of the multiple storage cavities 11. Each air supply component 41 includes a main duct 411 and two auxiliary ducts 412. The main duct 411 can be vertically installed within the cavity 13, with one end connected to the outside of the base 1. Specifically, the top of the main duct 411 can pass through the cavity 13 and the cover plate 16 to connect to an external air conditioner. Each main duct 411 can correspond to one external air conditioner, which can be connected to the main duct 411 via a duct. The two auxiliary ducts 412 correspond one-to-one with two corresponding air outlets 15, and both ends of the auxiliary ducts 412 are connected to the corresponding main duct 411 and the corresponding air outlet 15, respectively. A solenoid valve 413 is installed on each auxiliary duct 412. The solenoid valve 413 controls the internal connectivity of the corresponding auxiliary duct 412.

[0044] In use, for example, when it is necessary to deliver hot air into the storage cavity 11, the solenoid valve 413 on the lower secondary pipe 412 is opened and the solenoid valve 413 on the upper secondary pipe 412 is closed. Then, the corresponding external air conditioner is turned on and the external air conditioner is turned on in heating mode. Air can be blown into the corresponding storage cavity 11 through the main pipe 411 and the lower secondary pipe 412.

[0045] In addition, such as Figure 1 and Figure 9As shown, the chemical product storage device also includes multiple sliding seats 7, each corresponding to a different base 2. The base 2 slides on its corresponding sliding seat 7. The sliding seats 7 are positioned at corresponding openings, extending through the openings. One end of each sliding seat 7 is located within the cavity 14, while the other end extends radially outward from the base 1. Extending one end of the sliding seat 7 to the outside of the base 1 facilitates placing the chemical drum on the base 2. Furthermore, in the event of leakage or other abnormalities, the chemical drum can be moved outside the base 1 via the base 2 to isolate it from other chemical drums, thereby improving safety. It should be noted that the size of the sliding seat 7 can be smaller than the size of the corresponding opening.

[0046] Furthermore, such as Figures 7-12 As shown, the drive assembly 5 is disposed within the cavity 14 and is used to selectively drive any one of the bases 2 to slide. For example, when a chemical drum experiences an abnormal situation such as leakage, the drive assembly 5 can selectively push the chemical drum outside the base 1 by cooperating with the corresponding base 2.

[0047] The drive assembly 5 includes a second motor 51, a connecting seat 52, and a hydraulic cylinder 53. The second motor 51 is fixedly connected to the bottom of the second cavity 14, and the axis of the output shaft of the second motor 51 can be collinear with the axis of the base 1. The upper and lower sides of the connecting seat 52 are fixedly connected to the output shaft of the hydraulic cylinder 53 and the second motor 51, respectively. The hydraulic cylinder 53 extends and retracts in the horizontal direction. The second motor 51 drives the hydraulic cylinder 53 to rotate through the connecting seat 52, so that the extension and retraction end of the hydraulic cylinder 53 can selectively engage with either base 2.

[0048] In use, when it is necessary to push a certain base 2 to the corresponding storage cavity 11, the second motor 51 is started. The rotation of the second motor 51 can drive the hydraulic cylinder 53 to rotate through the transmission of the connecting seat 52. When the extension end of the hydraulic cylinder 53 rotates to correspond to the base 2, the second motor 51 is stopped and the hydraulic cylinder 53 is started to extend, thereby realizing the pushing of the base 2 to the outside of the storage cavity 11.

[0049] Furthermore, such as Figures 9-12As shown, an arc-shaped push plate 54 is fixedly connected to the telescopic end of the hydraulic cylinder 53, and the push plate 54 is coaxially arranged with the motor 51. A downward-opening L-shaped limiting plate 21 is provided on the side of the base 2 facing the motor 51. The limiting plate 21 includes a horizontal part 211 and a vertical part 212, with the side of the horizontal part 211 away from the base 2 fixedly connected to the vertical part 212. This defines a mating cavity 213 between the base 2, the horizontal part 211, and the vertical part 212. When the push plate 54 rotates with the hydraulic cylinder 53, it selectively passes through the mating cavity 213. When the push plate 54 is located within the mating cavity 213, the hydraulic cylinder 53 is activated. The telescopic movement of the hydraulic cylinder 53, through the cooperation of the push plate 54 and the limiting plate 21, drives the base 2 to move back and forth, thus not only pushing the base 2 out of the corresponding storage cavity 11 but also pulling the base 2 back into the corresponding storage cavity 11. Simply rotating the hydraulic cylinder 53 disengages the push plate 54 from the limiting plate 21, making it more convenient and flexible to use.

[0050] As an optional embodiment, the vertical portion 212 is also constructed in an arc shape in the vertical direction, and the vertical portion 212 is coaxially arranged with the push plate 54. This arrangement allows the vertical portion 212 to be extended in length without affecting the rotation of the push plate 54, thereby increasing the contact area between the vertical portion 212 and the push plate 54. This makes the push plate 54 more secure and stable when it engages with the limiting plate 21.

[0051] In addition, such as Figure 1 and Figure 3 As shown, the sliding seat 7 has two limiting grooves 71, which are symmetrically arranged on both sides of the base 2 in the direction of movement, and their length direction is the same as the direction of movement of the base 2. Multiple pulleys 22 are provided at the bottom of the base 2, symmetrically arranged on both sides of the base 2 in the direction of movement. Each pulley 22 corresponds to one of the limiting grooves 71 on both sides, and each pulley 22 is positioned within its corresponding limiting groove 71. The presence of pulleys 22 at the bottom of the base 2 reduces the friction between the base 2 and the corresponding sliding seat 7, thus making it easier for the base 2 to move the chemical drum. Furthermore, the limiting grooves 71 provide orientation; the cooperation between the pulleys 22 and the limiting grooves 71 allows the base 2 to move in a directional manner, making its movement more stable and improving the stability of the chemical drum during movement.

[0052] In addition, such as Figure 7As shown, the top of the base 2 is provided with a positioning groove 23 for positioning the chemical drum. When the chemical drum is placed on the base 2, it can be placed in the positioning groove 23, thereby quickly positioning the chemical drum. Furthermore, the positioning groove 23 can also limit the movement of the chemical drum to a certain extent, improving its stability. The shape of the positioning groove 23 can be set according to the actual shape of the chemical drum. For example, in this application, the vertical cross-sectional shape of the positioning groove 23 can be circular.

[0053] In addition, such as Figure 2 As shown, the chemical product storage device also includes multiple safety monitoring components 6, each corresponding to a top plate 32. These components are installed at the bottom of their respective top plates 32 and are used to monitor the safety of the chemical drums. Each safety monitoring component 6 includes a temperature sensor, a gas sensor, and a liquid sensor. The temperature sensor primarily monitors temperature changes within the corresponding storage chamber 11, while the gas and liquid sensors monitor for leaks from the chemical drums within the corresponding storage chamber 11.

[0054] The temperature sensor can be an infrared temperature sensor, which avoids direct contact with the chemical product, is corrosion-resistant, and has a fast response. The gas sensor can be an ultrasonic sensor, which detects gas leaks by detecting changes in sound velocity. The liquid sensor can be an ultrasonic level sensor, which can measure liquid level non-contactly. Of course, other suitable sensors can also be used for temperature, gas, and liquid sensors, depending on the specific operating conditions. It should be noted that the safety monitoring component 6 can also include other types of sensors, such as pressure sensors, which can be arranged according to the actual operating conditions. When the safety monitoring component 6 detects a malfunction in a chemical drum, the drive component 5 and the sealing component 3 can work together to push the base 2 outside the seat 1, thereby protecting other chemical drums and diluting the density of the diffused gas.

[0055] The chemical product storage device may also include a controller, which can be electrically connected to motor 31, motor 51, hydraulic cylinder 53, external air conditioner, and safety monitoring component 6. The controller can monitor information from safety monitoring component 6, analyze and process the received information, and then control motor 31, motor 51, hydraulic cylinder 53, and external air conditioner to perform corresponding actions.

[0056] For example, when the safety monitoring component 6 detects a gas leak inside a chemical drum, it transmits a signal to the controller. The controller first controls the corresponding motor 31 to rotate, disengaging the corresponding sealing plate 33 from the corresponding inlet 12. Then, it controls the corresponding motor 51 to rotate. When the corresponding hydraulic cylinder 53 rotates to the position where it engages with the corresponding base 2, the controller stops the motor 51 and extends the hydraulic cylinder 53, thereby pushing the base 2 and the corresponding chemical drum out of the seat 1, thus improving safety.

[0057] The chemical product storage device may also include an alarm, which is electrically connected to the controller. When the safety monitoring component 6 detects a gas leak in a chemical drum, the controller will activate the alarm to sound, so that the operator can detect and handle the situation in a timely manner.

[0058] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
