Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a reaction vessel feeding device. Background Technology

[0002] The feed inlet of most reactors is located at the top of the reactor, which is relatively high. When feeding, the staff usually have to manually lift the raw materials, raise them to the feed inlet of the reactor, and then pour the raw materials into the reactor from the feed inlet. This makes the feeding work not only arduous but also inefficient.

[0003] To address the aforementioned problems, those skilled in the art have made improvements to the existing technology. For example, a reaction vessel with convenient feeding, disclosed in CN214182987U, includes a reaction vessel body with a feed hopper connected to the top of the reaction vessel body. A feeding device is provided outside the reaction vessel body, including a lift, a feeding box, and a push rod. The lift is placed outside the reaction vessel body, the feeding box is horizontally rotatably connected to the lift, and the push rod is slidably connected to the lift. The sliding direction of the push rod is horizontal and perpendicular to the rotation axis of the feeding box. The push rod is also rotatably connected to the lift, and the end of the push rod away from the lift is rotatably connected to the bottom of the feeding box. The push rod is located on the side of the support rod away from the reaction vessel body, which can achieve automatic feeding. However, the feeding box in the above device can only move up and down with the lift and cannot move horizontally, which makes it impossible to feed the feeding port near the center of the reaction vessel, and it is still inconvenient to use.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

The baffle 263 cooperates with the first circulation groove (the baffle 263 has a through hole for the sliding sleeve shaft 262 to pass through, and a guide post that cooperates with the first circulation groove is provided on the inner side wall of the through hole). The bottom of the baffle 263 passes through the sliding seat 25 and bends towards the material box 252. The bent part of the baffle 263 can seal the material box 252 to prevent material leakage. An avoidance groove that cooperates with the baffle 263 is provided on the sliding seat 25. A top rotating shaft 27 is rotatably mounted above the central rotating shaft 26. A fixed sleeve shaft 272 is mounted on the top rotating shaft 27, and a connecting protrusion is provided on the top surface of the sliding seat 25. The fixed sleeve shaft 272 is fixedly connected to the connecting protrusion, and the sliding sleeve shaft 262 is rotatably connected to the connecting protrusion. A second circulation groove is provided on the top rotating shaft 27 (its mechanism and structure are the same as those of the first circulation groove). The fixed sleeve shaft 272 cooperates with the first circulation groove (the cooperation method is the same as that of the baffle 263 and the first circulation groove).

[0024] See Figures 1-3A mounting base 28 is slidably provided on the end plate 211. A drive shaft 29 is rotatably provided on the mounting base 28. The drive shaft 29 is connected to the output shaft of the drive component 291. The drive component 291 is provided on the mounting base 28. A drive gear 292 is rotatably provided on the drive shaft 29. A ratchet is provided on one side wall of the drive gear 292. The ratchet, drive gear 292 and drive shaft 29 are concentric. A unidirectional rotatable pawl is provided on the drive shaft 29. A bottom gear 241 is provided on the bottom rotating shaft 24. A middle gear 261 is provided on the middle rotating shaft 26. A top gear is provided on the top rotating shaft 27. The bottom gear 241, middle gear 261 and top gear 271 can all mesh with the drive gear 292, but the bottom gear 241, middle gear 261 and top gear 271 do not mesh with the drive gear 292 at the same time. A rotating sleeve shaft 293 is rotatably mounted on the drive shaft 29. A ratchet is provided on the side wall of one end of the rotating sleeve shaft 293. The ratchet, the rotating sleeve shaft 293 and the drive shaft 29 are concentric. A unidirectional rotatable anti-racket is rotatably mounted on the drive shaft 29. A switching seat is provided on the rotating sleeve shaft 293. A third circulation groove is provided on the surface of the rotating sleeve shaft 293 (its structure is the same as the first circulation groove). The switching seat cooperates with the third circulation groove (its cooperation method is the same as that of the baffle 263 and the first circulation groove). A connecting rod 294 is rotatably mounted between the switching seat and the end plate 211 (that is, one end of the connecting rod 294 is rotatably connected to the switching seat, and the other end of the connecting rod 294 is rotatably connected to the end plate 211).

[0025] See Figures 1-3 Preferably, the top surface of the sliding seat 25 near the material box 252 is provided with a support plate 253, the fixed sleeve shaft 272 is fixedly connected to the support plate 253, and the sliding sleeve shaft 262 is rotatably connected to the support plate 253, which can improve the stability of the device.

[0026] See Figures 1-3 Preferably, the belt drive in this application can be replaced with a chain drive to ensure good transmission efficiency. The addition of transmission gears and the matching of the chain and transmission gears are routine technical operations for those skilled in the art, and therefore will not be described in detail.

[0027] See Figures 1-3 Preferably, the drive unit 291 is a rotary motor that can provide sufficient power.

[0028] In the implementation of this utility model: the user first adds an appropriate amount of material to the material bin 252, then starts the drive unit 291. The drive unit 291 reverses, at which point the positive ratchet does not engage with the positive pawl, and the negative ratchet engages with the negative pawl. The drive gear 292 does not rotate, and the rotating sleeve shaft 293 rotates, causing the switching seat to move along the rotating sleeve shaft 293, thereby driving the mounting seat 28 to move until the drive gear 292 meshes with the bottom gear 241. Then the drive unit 291 rotates forward, at which point the positive ratchet does not engage with the positive pawl, and the negative ratchet engages with the negative pawl. The rotating sleeve shaft 293 does not rotate, and the drive gear 292 rotates, driving several reciprocating screws 22 to rotate synchronously. The two reciprocating seats 221 on the same reciprocating screw 22 approach each other, and the lifting seat 21 rises to a suitable height (setting the lifting seat 2). 1. The weight of the sliding seat 25 and the material box 252, as well as the load weight, are adjusted. The inclination of the reciprocating groove on the reciprocating screw 22 and the friction between the slider 231 and the limit rod 232 are adjusted so that the lifting seat 21 moves only when the bottom rotating shaft 24 rotates. Then the drive component 211 reverses, and the mounting seat 28 moves until the drive gear 292 meshes with the top gear 271. The drive component 211 rotates forward, so that the fixed sleeve shaft 272 drives the sliding seat 25 to move to the bottom of the material box 252 and correspond to the feed port of the reactor. Then the drive component 211 reverses, so that the drive gear 292 meshes with the middle gear 261. The drive component 211 rotates forward, and the middle rotating shaft 26 drives the sliding sleeve shaft to rotate synchronously, so that the baffle 263 moves away from the material box 252, and the material in the material box 252 falls into the reactor.

[0029] This utility model provides a reactor feeding device, the advantages of which are:

[0030] 1. By setting up the feeding component, the lifting and horizontal movement of the material box can be completed automatically, expanding the movement range of the material box and thus meeting the feeding needs of different feed ports of the reactor. It has strong applicability and can realize the automatic opening and closing of the material box. The feeding process does not require manual intervention and ensures good feeding efficiency.

[0031] 2. This device only requires one drive component to move, which reduces manufacturing and operating costs and meets the requirements of enterprises to reduce costs and increase efficiency.

[0032] In summary, the beneficial effects of this utility model are: it can automatically complete the lifting and translating of the material box, and can automatically switch the opening and closing state of the material box, thus expanding the applicable scope of the device and improving the feeding efficiency.

[0033] Of course, there may be other embodiments of this utility model.
