Description

Technical Field

[0001] The present invention belongs to the field of reaction kettles, and particularly relates to a connection mechanism for a reaction kettle cover body. Background Art

[0002] A reaction kettle is a key device for chemical reactions, which can provide a suitable reaction environment, promote chemical reactions under specific conditions such as temperature and pressure, realize material transformation, and at the same time can achieve uniform mixing of materials, enabling each reactant to fully contact and creating good conditions for the reaction.

[0003] The main structure of a reaction kettle includes a kettle body, a cover body, a stirring device, and an instrument and control system. The kettle body and the cover body of the reaction kettle are generally connected by welding, bolt connection, and hinge structure.

[0004] Currently, the existing connection structures of reaction kettle cover bodies are relatively single in the opening method, mostly only able to achieve simple opening and closing actions, and cannot meet the requirements of complex processes for multi-angle operations of the cover body, such as horizontal rotation, flipping and other actions, which limits the application of reaction kettles in high-end fields such as new energy, pharmaceuticals, and aerospace. For example, after vertical rotation and opening, horizontal rotation is required to avoid the operation area; and in the process of separating the cover body from the kettle body of the existing connection structure, a relatively large external force is often required, especially in the sealed state, a large external force needs to be applied to separate the cover body from the kettle body, which not only increases the labor intensity of the operator but also poses a safety hazard. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a connection mechanism for a reaction kettle cover body to solve the problems mentioned in the above background art.

[0006] In order to achieve the above object, the embodiments of the present application provide the following technical solutions: A connection mechanism for a reaction kettle cover body includes a first rotating part and a pressing frame. The first rotating part is arranged between the kettle body and the kettle cover, driving the kettle cover to rotate in the horizontal and vertical directions. The pressing frame includes a pressing ring rotatably connected to the upper end of the kettle body through a second rotating part. The pressing ring has a semi-circular structure, and two locking components for pressing down and tightly pressing the pressing ring are arranged on the upper side of the pressing ring. The locking components control the pressing ring to press down so that the kettle body and the kettle cover are tightly attached while limiting the kettle cover. An auxiliary opening and closing component is jointly arranged between the second rotating part and the upper end of the kettle body, and the auxiliary opening and closing component cooperates with the second rotating part to drive the cover body and the upper end of the kettle body to be initially separated.

[0007] According to an advantageous embodiment, the first rotating part includes an ear seat one fixedly arranged on the outer side of the kettle body and close to the upper end. A disc-shaped rotating seat is rotatably arranged on the upper side of the ear seat one.

[0008] According to an advantageous embodiment, the second rotating part includes two second ear seats fixedly arranged at the edge of the upper end surface of the kettle body. A rotating shaft is rotatably arranged between the two second ear seats. A convex connecting block is fixedly arranged on the rotating shaft, and the connecting block is connected with the pressing ring.

[0009] According to an advantageous embodiment, a notch groove is formed at the position of the pressing ring opposite to the connecting block. An activity groove is formed on the inner side wall of the notch groove. A connecting shaft is fixedly arranged between the upper and lower inner walls of the activity groove. One end of the connecting block extends into the activity groove and is slidably connected with the connecting shaft.

[0010] According to an advantageous embodiment, an annular resisting strip is fixedly arranged on the upper side of the skirt of the kettle cover, and the cross section of the resisting strip is set as a first inclined plane.

[0011] According to an advantageous embodiment, a second inclined plane adapted to the first inclined plane of the resisting strip is arranged on the inner ring of the pressing ring, and the first inclined plane and the second inclined plane are in movable contact.

[0012] According to an advantageous embodiment, two symmetrically arranged inner grooves are formed on the outer side of the pressing ring.

[0013] According to an advantageous embodiment, the locking assembly includes a plurality of screw rods rotatably arranged on the pressing ring. A gear is fixedly arranged at the upper end of the screw rod. An arc-shaped driving strip concentric with the pressing ring is rotatably arranged on the upper side of the pressing ring. A plurality of groups of racks are arranged on the outer side of the arc-shaped driving strip. The rack is composed of a plurality of tooth blocks fixedly arranged on the outer side of the arc-shaped rack and evenly distributed along the arc direction of the arc-shaped driving strip. The rack is meshed with the corresponding gear. A thread groove is formed at the position of the edge of the upper end surface of the kettle body opposite to the screw rod, and the screw rod is in threaded connection with the corresponding thread groove.

[0014] According to an advantageous embodiment, guide sleeves are movably sleeved on the front and rear end surfaces of the arc-shaped driving strip, and the guide sleeves are fixedly connected with the upper side of the pressing ring.

[0015] According to an advantageous embodiment, two symmetrically arranged strip-shaped grooves are formed at the position of the upper end surface of the kettle body close to the notch groove. The auxiliary opening and closing mechanism includes a guide rod fixedly arranged in the strip-shaped groove. A slider is slidably arranged on the guide rod. A return spring sleeved on the surface of the guide rod is fixedly arranged between one side of the slider and the opposite inner wall of the strip-shaped groove. A shovel plate is fixedly arranged on the slider. A driven seat is fixedly arranged on the side of the shovel plate away from the kettle cover. A fitting groove with a slope structure is formed at the position of the skirt of the kettle cover close to the shovel plate. One side of the shovel plate close to the fitting groove is set as a third inclined plane. A ball is rotatably arranged on the surface of the third inclined plane. The left and right ends of the rotating shaft both movably penetrate through the corresponding second ear seats and are fixedly connected with driving discs. A dial block is fixedly arranged on the outer side wall of the driving disc, and the dial block is in movable contact with the corresponding driven seat.

[0016] Compared with the prior art, a reactor cover connection mechanism provided by an embodiment of the present invention has the following beneficial effects: 1. In the present invention, through the cooperation of the first rotating part and the pressing frame, compared with the traditional single-axis hinge, it can not only make the kettle cover rotate flexibly in the horizontal and vertical directions, realizing multi-angle opening and closing operations, but also ensure the sealing performance and stability after the kettle cover is connected to the kettle body.

[0017] 2. In the present invention, the pressing ring applies a uniform downward inclined pressure to the kettle cover through the locking assembly, ensuring that the kettle cover is closely attached to the kettle body and improving the sealing performance.

[0018] 3. In the present invention, when the pressing ring rotates and moves away from the kettle cover, it can simultaneously cooperate with the second rotating part and the auxiliary opening and closing assembly to generate an upward inclined thrust on the kettle cover, initially separating the kettle cover from the upper end of the kettle body, making it more labor-saving for manual opening of the cover and effectively reducing the labor intensity of the operator. At the same time, the introduction of the auxiliary opening and closing assembly avoids the safety hazards caused by sudden pressure release in the traditional connection structure, and the operation process is more stable and reliable.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1 -Attached Figure 11 The present application is further described in detail.

[0032] Please refer to Figure 1 and Figure 2 A reaction kettle cover connecting mechanism includes a rotating part 1 and a pressing frame 2. The rotating part 1 is arranged between the kettle body 3 and the kettle cover 4, driving the kettle cover 4 to rotate horizontally and vertically. The pressing frame 2 is rotatably mounted on the upper end of the kettle body 3, and is used to press on the surface of the upper side of the skirt of the kettle cover 4, tightly pressing the kettle cover 4 on the upper end of the kettle body 3 while limiting the rotation of the kettle cover 4.

[0033] See also Figure 1 In order to improve the rotational freedom of the kettle cover 4, the rotating part 1 includes an ear seat 11 fixedly arranged on the outside of the kettle body 3 and close to the upper end, a disc-shaped rotating seat 12 is rotatably arranged on the upper side of the ear seat 11, a connecting arm 13 is rotatably arranged on the rotating seat 12, and one end of the connecting arm 13 away from the rotating seat 12 is fixedly connected to the kettle cover 4.

[0034] During specific operation, the kettle cover 4 rotates in the vertical direction relative to the rotating seat 12 through the connecting arm 13, and the kettle cover 4 can also rotate horizontally through the rotating seat 12, so that the kettle cover 4 can rotate and open with multiple degrees of freedom during actual application.

[0035] See also Figure 1 , Figure 8 and Figure 10The pressing frame 2 includes a rotating part 21 disposed on the upper end surface of the kettle body, and a pressing ring 22 is disposed on the rotating part 21. The pressing ring 22 is in a semicircular structure, and an inner groove 8 is provided on the outer side of the pressing ring 22 for easy manual gripping, and two sets of locking components 23 are disposed on the upper side of the pressing ring 22 for pressing down and tightening the pressing ring 22. The pressing ring 22 rotates relative to the kettle body 3 through the rotating part 21 at the upper end of the kettle body 3, so that the pressing ring 22 can rotate and cover the upper side of the skirt of the kettle cover 4 after the kettle cover 4 is connected to the kettle body 3, and then the locking component 23 controls the pressing ring 22 to press the kettle cover 4, so that the kettle cover 4 and the upper end of the kettle body 3 are tightly fitted, ensuring the sealing after the kettle cover 4 and the kettle body 3 are connected.

[0036] See also Figure 3 , Figure 8 , Figure 9 and Figure 10 The rotating part 21 includes two ear seats 211 fixedly arranged on the upper end surface edge of the kettle body 3, a rotating shaft 212 is arranged between the two ear seats 211 for common rotation, a convex connecting block 213 is fixedly arranged on the rotating shaft 212, and the connecting block 213 is connected to the pressing ring 22. A notch groove 221 is provided at the position of the pressing ring 22 facing the connecting block 213, a movable groove 222 is provided on the inner side wall of the notch groove 221, a connecting shaft 6 is fixedly arranged between the upper and lower inner walls of the movable groove 222, and one end of the connecting block 213 is movably extended into the movable groove 222 and is slidably connected to the connecting shaft 6. The pressing ring 22 can rotate relative to the kettle body 3 through the rotating shaft 212, and when the pressing ring 22 is horizontally pressed against the upper side of the skirt of the kettle cover 4, the pressing ring 22 can slightly float up and down relative to the kettle body 3 through the connecting shaft 6, so as to avoid interference caused by the pressing ring 22 when the kettle cover 4 is pressed by the locking assembly 23.

[0037] See also Figures 4 - 7 The upper side of the skirt of the kettle cover 4 is fixedly provided with a ring-shaped interference strip 7, and the cross section of the interference strip 7 is set as a slope surface 1. The inner ring of the pressure ring 22 is provided with a slope surface 2 adapted to the slope surface 1 of the interference strip 7, and the slope surface 1 flexibly interferes with the slope surface 2. The pressure ring 22 is pressed on the upper side of the skirt of the kettle cover 4, and the slope surface 2 of the pressure ring 22 fits with the slope surface 1 of the interference strip 7, so that the pressure ring 22 can generate an oblique downward pressure on the kettle cover 4, so that the kettle cover 4 fits tightly with the kettle body 3 and can limit the horizontal position of the kettle cover 4.

[0038] See also Figure 3 , Figure 6 , Figure 7 and Figure 8, the locking assembly 23 includes a plurality of screw rods 231 rotatably arranged on the pressing ring 22. A gear 232 is welded to the upper end of the screw rod 231. An arc-shaped driving bar 233 concentric with the pressing ring 22 is rotatably arranged above the pressing ring 22. Guide sleeves 235 for guiding the arc-shaped driving bar 233 are movably sleeved on the surfaces of the head and tail ends of the arc-shaped driving bar 233. The guide sleeves 235 are fixedly connected to the upper side of the pressing ring 22. A plurality of groups of racks 234 are arranged on the outer side of the arc-shaped driving bar 233. The racks 234 are engaged with the corresponding gears 232. Thread grooves 9 are formed in the upper end surface edge of the kettle body 3 at positions opposite to the screw rods 231. The screw rods 231 are threadedly connected to the corresponding thread grooves 9. After the pressing ring 22 rotates above the skirt of the kettle lid 4, there is a certain gap between the pressing ring 22 and the upper side of the skirt of the kettle lid 4 at this time. At the same time, the lower end of the screw rod 231 is opposite to the port of the thread groove 9 on the upper end surface of the kettle body 3. At this time, the staff simultaneously pushes the two arc-shaped driving bars 233 to rotate above the pressing ring 22, so that the racks 234 drive the corresponding screw rods 231 to rotate. The screw rods 231 rotate into the thread grooves 9. At the same time, the descending screw rods 231 will drive the pressing ring 22 to descend and gradually contact and press against the contact bars 7 on the upper side of the skirt of the kettle lid 4.

[0039] During specific operation, after the kettle lid 4 can be covered on the upper end surface of the kettle body 3, the pressing ring 22 can rotate through the rotating shaft 212 and then cover above the skirt of the kettle lid 4. Then, when the staff simultaneously pulls the two arc-shaped driving bars 233 closer to each other, the pressing ring 22 can be lowered to contact the contact bars 7 on the upper side of the skirt of the kettle lid 4, locking the kettle lid 4 and the kettle body 3. When the kettle lid 4 needs to be opened, only by pushing the two arc-shaped driving bars 233 away from each other can the pressing ring 22 be loosened from the kettle lid 4. Then, the staff holds the left and right inner grooves 8 outside the pressing ring 22 with both hands and rotates the pressing ring 22 forward, and the pressing ring 22 can be moved away from the kettle lid 4, as Figure 10 shown, and then manually push the kettle lid 4 to open, as Figure 11 shown.

[0040] Refer to Figures 3 - 5, an auxiliary opening and closing assembly 5 for assisting the separation of the kettle lid 4 from the kettle body 3 is jointly provided between the left and right ends of the rotating shaft 212 and the upper end of the kettle body 3. Two symmetrically arranged strip-shaped grooves are formed in the upper end surface of the kettle body 3 near the notch groove 221. The auxiliary opening and closing assembly 5 includes guide rods 51 fixedly arranged in the strip-shaped grooves. Sliders 52 are slidably arranged on the guide rods 51. A return spring 57 sleeved on the surface of the guide rod 51 is jointly fixed between one side of the slider 52 and the relatively symmetric inner walls of the strip-shaped grooves. A shovel plate 53 is fixedly arranged on the slider 52. A driven seat 54 is fixedly arranged on the side of the shovel plate 53 away from the kettle lid 4. A fitting groove 10 with a slope structure is formed in the skirt of the kettle lid 4 near the shovel plate 53. One side of the shovel plate 53 close to the fitting groove 10 is set as a third slope surface. A ball (not shown in the figure) is rotatably arranged on the surface of the third slope surface to reduce the friction after being inserted into the fitting groove 10. The left and right ends of the rotating shaft 212 both movably penetrate through the corresponding second ear seats 211 and are fixedly connected with driving disks 55. A dial block 56 is fixedly arranged on the outer side wall of the driving disk 55. The dial block 56 is in movable contact with the corresponding driven seat 54.

[0041] Specifically, when the staff needs to open the kettle lid 4, they need to first unlock the pressure ring 22 by pulling the arc-shaped driving bar 233, and then rotate the pressure ring 22 forward by a certain angle by rotating the pressure ring 22 forward. The pressure ring 22 rotates forward through the rotating shaft 212. The rotation of the rotating shaft 212 synchronously drives the dial blocks 56 on the two driving disks 55 to rotate. After the dial blocks 56 rotate by a certain angle, they contact the driven seat 54 and push the driven seat 54 and the shovel plate 53 to move towards the skirt of the kettle lid 4. Finally, the shovel plate 53 is inserted into the fitting groove 10 on the skirt of the kettle lid 4, generating an obliquely upward thrust on the kettle lid 4 and finally causing the kettle lid 4 to separate from the kettle body 3 with a gap, making it more labor-saving for the subsequent manual opening of the kettle lid 4.

[0042] The working process of the entire connection mechanism is as follows. The kettle lid 4 can rotate relative to the kettle body 3 in the horizontal and vertical directions through the first rotating part 1. When the kettle lid 4 rotates and covers the upper port of the kettle body 3, then rotate the pressure ring 22 so that the pressure ring 22 covers the upper side of the side skirt of the kettle lid 4. After that, by pushing the two arc-shaped driving bars 233 on the pressure ring 22 outward, the kettle lid 4 can be pressed tightly on the upper port of the kettle body through the pressure ring 22.

[0043] When opening the kettle lid subsequently, by pushing the two arc-shaped driving bars 233, the pressure of the pressure ring 22 is released. Then, rotate the pressure ring 22 forward through the second rotating part 21 so that the pressure ring 22 can be moved away from the kettle lid 4. At the same time, the second rotating part 21 can cooperate with the auxiliary opening and closing assembly 5 to drive the kettle lid 4 to tilt and separate from the kettle body 3 through the shovel plate 53, facilitating the opening of the kettle lid 4.

[0044] The above are only embodiments of the present invention, and do not thereby limit the patent scope of the present invention.
