Description

Technical Field

[0001] This invention relates to the field of chemical conveying technology, specifically a conveying device for the production of anhydrous hydrogen fluoride. Background Technology

[0002] Industrial anhydrous hydrogen fluoride is a widely used chemical product. It is a colorless, fuming liquid containing more than 99% hydrofluoric acid. It is mainly used to produce fluoride salts, fluoroalkanes, fluorinated refrigerants, glass corrosion agents, wood impregnation agents, and elemental fluorine electrolysis agents. Industrial anhydrous hydrogen fluoride is non-flammable, highly toxic, extremely corrosive and irritating. It readily volatilizes into fumes at room temperature and ambient temperature. Therefore, anhydrous hydrogen fluoride is generally transported in tank containers.

[0003] Because tank containers containing anhydrous hydrogen fluoride are large in both weight and volume, they require the use of spreaders for loading and unloading before and after transport. With a fixed rated mass of tank containers, the market demand for the effective load-bearing capacity of the tanks is constantly increasing. As a result, the size and volume of tank containers are constantly increasing, which affects the overall structural strength of the tank containers.

[0004] Existing technology, patent CN114476393B, discloses a frame connection structure for tank containers, including a frame and a connecting assembly. The frame is fixedly connected to the tank body of the tank container via the connecting assembly. The connecting assembly includes an annular support cylinder with a circular arc cross-section. The annular support cylinder cooperates with limiting pads evenly distributed on the inner sides of both ends of the frame. Through the cooperation of the annular support cylinder and the limiting pads, the connection between the frame and the tank body is expanded from a point to a surface, and only the limiting pads are fixedly connected to the frame, making the connection relationship of the connecting assembly relatively simple. The circular ring-shaped support cylinder provides a smooth transition at the connection with the tank body, greatly reducing stress concentration and increasing the structure's resistance to bending deformation, thus addressing the aforementioned problems. However, when hoisting the massive tank and frame assembly, a specific part of the frame's top beam is typically hooked directly. Due to the container's own weight, the load-bearing area of ​​the frame is relatively small when lifted, potentially causing the frame's top beam to bend or even break. The aforementioned patented invention does not have a mechanism or effect to solve this problem, which in turn affects the overall structural strength of the container and is detrimental to the long-distance transportation of anhydrous hydrogen fluoride. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a conveying device for the production of anhydrous hydrogen fluoride, which solves the problem that the small contact area between the spreader and the top beam of the frame affects the overall structural strength of the container during the lifting operation of tank container loading and unloading.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conveying device for the production of anhydrous hydrogen fluoride, comprising an outer frame consisting of a longitudinal frame and a transverse frame connected together, and a tank body installed inside the two. The transverse frame is provided with two sets of lifting mechanisms that hug the outside of the tank body. Each set of lifting mechanisms consists of two and is symmetrically arranged about the tank body.

[0007] The lifting mechanism includes a base that engages with a transverse frame. The bottom of the base is a hinge structure and is rotatably connected to a first force plate. One side of the first force plate is attached to the outer surface of the tank. A groove is provided inside the first force plate and a second force plate located in the groove is slidably connected to it. One side of the second force plate is also attached to the outer surface of the tank. The second force plate can extend into or be pulled out along the arc of the first force plate to change the overall length of the lifting mechanism.

[0008] In each set of lifting mechanisms, the one on the right side has a first docking plate fixedly connected to the tail end of its second force plate, and a first latch is provided at the bottom end of the first docking plate. In each set of lifting mechanisms, the one on the left side has a second docking plate fixedly connected to the tail end of its second force plate, and a second latch is provided at the top end of the second docking plate. A latching block is engaged inside the second latch. When the first docking plate and the second docking plate are docked vertically, the latching block can penetrate upwards into the first latch, thus completing the docking of the left and right sides of each set of lifting mechanisms.

[0009] Each of the bases has two corresponding left and right lifting rings fixed to its top for connecting the hooks of the lifting device.

[0010] Preferably, there are two longitudinal frames located at both ends of the tank, and four transverse frames connected at the four corners between the two longitudinal frames. Each transverse frame has multiple equidistant holes.

[0011] Preferably, the base also has a corresponding insertion hole, and the same insertion rod passes through the insertion hole and the insertion hole on the base, which is used to position the lifting mechanism on the transverse frame.

[0012] Preferably, the bottom end of the second docking plate has a threaded hole that extends upward through the second bayonet, and a lead screw is threaded through the threaded hole. The top end of the lead screw is rotatably connected to the bayonet block. Rotating the lead screw can drive the bayonet block to move, making it easier to push it into the first bayonet block.

[0013] Preferably, the first docking plate and the second docking plate are adapted to each other in shape and can be attached vertically. The top of the first docking plate is an arc-shaped structure and is attached to the outer surface of the tank. When the two lifting mechanisms are docked, the first docking plate is at the lowest point of the tank.

[0014] Preferably, the center of the cross-sections of the first force plate, the second force plate, and the tank body are at the same position, the arc length of the second force plate is greater than the arc length of the first force plate, and the top of the chute passes through the top of the first force plate while the bottom end is higher than the bottom end face of the first force plate.

[0015] Preferably, two baffles are fixed to the two sides of the second force plate at its top position, and the baffles slide through the grooves on the side surface of the first force plate.

[0016] Preferably, the baffle can be moved upward from inside the chute, and can be moved downward to the bottom of the chute by being blocked by the bottom edge of the first force plate. In each set of lifting mechanisms, the bottom ends of the second force plates on both sides are blocked by the first docking plate and the second docking plate respectively, so that the second force plates are always dynamically connected to the first force plate.

[0017] Preferably, the cross-section of the transverse frame is an irregular triangular shape, and the top of the base has a groove that matches the shape of the transverse frame, so that the base exerts an upward lifting force on the transverse frame during hoisting.

[0018] Preferably, the first load-bearing plate is movable within the hinge at the bottom of the base, making the process of installing the lifting mechanism on the transverse frame more flexible and simple.

[0019] Compared with the prior art, the present invention provides a conveying device for the production of anhydrous hydrogen fluoride, which has the following advantages:

[0020] During loading and unloading, the lifting device uses a hook-and-lift mechanism instead of directly hooking and lifting the frame itself. The lifting mechanism connects to the transverse frame and also holds onto the tank body, increasing the stress area of ​​the entire container during lifting, preventing damage to the tank container frame, and thus ensuring the safety and stability of the container during transportation after loading.

[0021] By setting two sets of spreader mechanisms on the transverse frame and connecting them together with a connecting rod, the spacing between the two sets of spreader mechanisms can be adjusted, making it convenient to use the same lifting device to lift tank containers of different sizes and lengths.

[0022] The second load-bearing plate is always dynamically connected to the first load-bearing plate. Regardless of whether a lifting mechanism is used, the first and second load-bearing plates will not naturally disconnect. Combined with the extensibility between the two, it is convenient to store and carry them. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Figure 1-6As an embodiment of the present invention, a conveying device for the production of anhydrous hydrogen fluoride includes an outer frame consisting of a longitudinal frame 1 and a transverse frame 11 connected together, and a tank 12 installed inside the two. There are two longitudinal frames 1, located at both ends of the tank 12, and four transverse frames 11, connected at the four corners between the two longitudinal frames 1. Each transverse frame 11 has multiple equidistant holes 111. Two sets of lifting mechanisms 2 are provided on the outside of the transverse frames 11, which hug the outside of the tank 12. There are two lifting mechanisms 2 in each set, which are symmetrically arranged about the tank 12. The distance between the two sets of lifting mechanisms 2 is adjusted according to the specifications of the lifting device used. During loading and unloading, the lifting device hooks the lifting mechanisms 2 instead of directly hooking the frame itself. The lifting mechanisms 2 are connected to the transverse frames 11 and hug the tank 12 at the same time, which increases the stress area of ​​the entire container during lifting, prevents damage to the frame of the tank container, and thus ensures the safety of the container during transportation after loading.

[0037] The lifting mechanism 2 includes a base 21 that engages with the transverse frame 11. The bottom of the base 21 is a hinge structure and is rotatably connected to a first force-bearing plate 22. One side of the first force-bearing plate 22 is attached to the outer surface of the tank body 12. A groove 221 is formed inside the first force-bearing plate 22, and a second force-bearing plate 23 located in the groove 221 is slidably connected to it. One side of the second force-bearing plate 23 is also attached to the outer surface of the tank body 12, and the second force-bearing plate 23 can extend into or be pulled out along the arc of the first force-bearing plate 22 to change the lifting mechanism 2. The base 21 also has a corresponding insertion hole on its overall length. The same insertion rod 211 passes through the insertion hole 111 and the insertion hole on the base 21. It is used to position the lifting mechanism 2 on the transverse frame 11. When it is necessary to change the distance between the two lifting mechanisms 2, the insertion rod 211 is pulled out and the base 21 is moved. Then the insertion rod 211 is reinserted into the corresponding two insertion holes. The second force plate 23 is stretched outward from the first force plate 22, which increases the contact surface between the entire lifting mechanism 2 and the tank 12.

[0038] Furthermore, in each set of lifting mechanisms 2, the right-side one has a first docking plate 24 fixedly connected to the tail end of its second force-bearing plate 23. The bottom end of the first docking plate 24 has a first latch 241. In each set of lifting mechanisms 2, the left-side one has a second docking plate 25 fixedly connected to the tail end of its second force-bearing plate 23. The top end of the second docking plate 25 has a second latch 251. A latching block 252 is engaged inside the second latch 251. When the first docking plate 24 and the second docking plate 25 are vertically aligned, the latching block 252 can penetrate upwards into the first latch 241, completing the docking of each set of left and right lifting mechanisms 2. The bottom end of the second docking plate 25 has a threaded hole that penetrates upwards through the second latch 251. A lead screw 253 is threaded through the threaded hole. The top end of the lead screw 253 is rotatably connected to the latching block 252. The rod 253 can drive the displacement of the locking block 252 to facilitate its insertion into the first locking slot 241. The first docking plate 24 and the second docking plate 25 are adapted to each other and can be attached vertically. The top of the first docking plate 24 is an arc-shaped structure and is attached to the outer surface of the tank body 12. When the two lifting mechanisms 2 are docked, the first docking plate 24 is at the lowest point of the tank body 12. The first docking plate 24 and the second docking plate 25 on both sides are docked and the locking block 252 is locked in the first locking slot 241. After docking, the set of lifting mechanisms 2 forms a lifting structure for the tank body 12 when it is lifted. Compared with directly lifting a certain part of the longitudinal frame 1 or the transverse frame 11, the arc-shaped lifting mechanism 2 provides an upward support force opposite to the gravity direction of the entire tank container, thereby reducing the deformation probability of the entire container after lifting.

[0039] The center of the cross-sections of the first force-bearing plate 22, the second force-bearing plate 23, and the tank body 12 are at the same location. The arc length of the second force-bearing plate 23 is greater than that of the first force-bearing plate 22. The top end of the groove 221 passes through the top of the first force-bearing plate 22, while the bottom end is higher than the bottom end face of the first force-bearing plate 22. Two baffles 231 are fixed to the top of the two sides of the second force-bearing plate 23. The baffles 231 slide through the groove 221 on the side surface of the first force-bearing plate 22. The baffles 231 can slide upward from the groove. The slide plate 221 moves out of the groove 221 and is blocked by the bottom edge of the first force plate 22, so it can move to the bottom of the slide 221. The bottom ends of the second force plates 23 on both sides of each set of lifting mechanism 2 are blocked by the first docking plate 24 and the second docking plate 25 respectively, so that the second force plates 23 are always dynamically connected in the first force plate 22. The first force plate 22 and the second force plate 23 will not be naturally disconnected regardless of whether the lifting mechanism 2 is used. The extensibility between the two makes it convenient to store and carry them.

[0040] Furthermore, each base 21 has two corresponding lifting rings 3 fixed to its top for connecting the hooks of the lifting device. The cross-section of the transverse frame 11 is an irregular triangular shape. The top of the base 21 has a groove that matches the shape of the transverse frame 11, so that the base 21 forms an upward lifting force on the transverse frame 11 during lifting. The first force plate 22 is movable in the hinge at the bottom of the base 21, making the process of installing the lifting mechanism 2 on the transverse frame 11 more flexible and simple. Since the two lifting rings 3 at the top of the base 21 are located on both sides of the groove at the top, the lifting rings 3 will not hinder the process when the base 21 is snapped upward along the bottom of the transverse frame 11. At the same time, the setting of the two lifting rings 3 can increase the force-bearing surface between the hooks, which improves the stability during lifting to a certain extent.

[0041] As described in the above embodiments, before loading and unloading, the two sets of lifting mechanisms 2 are first installed on the two transverse frames 11 located on both sides above the tank body 12. During installation, the groove at the top of the base 21 is moved vertically upward from the bottom of the transverse frame 11, and the insertion hole on the base 21 is aligned with the insertion hole 111 on the transverse frame 11. Then, the insertion rod 211 is simultaneously inserted into the insertion holes of the two structures to complete the positioning of the lifting mechanism 2 on the transverse frame 11. Subsequently, the second force plates 23 on the left and right sides of each set are pulled down along the arc surface of the tank body 12 until the first docking plate 24 and the second docking plate 25 at the bottom of the second force plates 23 on both sides are aligned vertically. Then, the screw 253 is rotated to drive the locking block 252 upward and firmly embed it into the first locking slot 241 to complete the docking of a set of lifting mechanisms 2. Finally, the lifting equipment is loaded. The hooks are respectively attached to the two lifting rings 3 at the top of the base 21. When the set of spreader mechanisms 2 is connected, it forms a lifting structure for the tank body 12 during lifting. Compared with directly lifting a certain part of the longitudinal frame 1 or the transverse frame 11, the arc-shaped spreader mechanism 2 provides an upward support force in the opposite direction of the gravity of the entire tank container, thereby reducing the probability of deformation of the entire container after lifting. When it is necessary to change the distance between the two spreader mechanisms 2, the insert rod 211 is pulled out and the base 21 is moved, and then the insert rod 211 is reinserted into the corresponding two insert holes. The second force plate 23 is stretched outward from the first force plate 22, which increases the contact area between the entire spreader mechanism 2 and the tank body 12, increases the force-bearing area of ​​the entire container during lifting, prevents damage to the frame of the tank container, and thus ensures the safety of the container during transportation after loading.

[0042] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
