Description

Technical Field

[0001] This application relates to the technical field of reaction kettles, and particularly to a feeding device for a reaction kettle. Background Art

[0002] A reaction kettle is a container that provides a place for chemical reactions and is commonly used in industrial production. The reaction kettle has a relatively large wall thickness and a stable internal environment, which can provide a stable reaction space and protect the staff from harm. The inlets of cylindrical reaction kettles are mostly located above the kettle body.

[0003] The existing utility model patent with the publication number CN215389182U discloses a reaction kettle, which includes a kettle body. The kettle body is provided with a liquid inlet, a liquid outlet, a solid inlet and a solid outlet. An activity plate is added. A support plate is provided on the inner wall of the kettle body. The activity plate is vertically slidably arranged between the support plate and the top of the kettle body, and a group of through holes are provided on the activity plate.

[0004] Regarding the above related technologies, the inventor believes that the feeding ports of the reaction kettle are all located at the top of the kettle body. When feeding materials, the materials fall and hit the liquid surface in the kettle body, and the liquid will splash, resulting in liquid droplets hanging on the upper part of the inner wall of the kettle body. During the reaction process, these hanging liquid droplets cannot contact the materials, so the reaction cannot be carried out. On the one hand, the utilization rate of raw materials is reduced, and on the other hand, the stains generated after these liquid droplets dry or solidify are difficult to clean. Utility Model Content

[0005] This application provides a feeding device for a reaction kettle, which can avoid liquid splashing during the feeding process of materials, the inner wall of the kettle body is not easy to hang with liquid droplets, improves the utilization rate of raw materials, and avoids the problem that it is difficult to clean after the liquid droplets dry or solidify.

[0006] The feeding device for a reaction kettle provided by this application adopts the following technical scheme:

[0007] The feeding device for a reaction kettle includes a kettle body and a feeding pipe. The feeding pipe is slidably connected to the kettle body in the vertical direction. A rack is fixed on the outer side wall of the feeding pipe in the vertical direction. A servo motor and a gear driven by the servo motor are arranged at the top of the kettle body. The gear meshes with the rack. A partition is slidably connected to the lower end of the feeding pipe. An electric cylinder is fixed on the outer wall of the feeding pipe, and the piston rod end of the electric cylinder is fixed to the partition.

[0008] By adopting the above technical solution, the operation of the servo motor is controlled to lower the height of the feed pipe, so that the lower end of the feed pipe is as close as possible to the liquid level. After the material is put into the feed hopper, the material falls onto the partition plate at the bottom through the feed pipe, and the partition plate supports the material to prevent the material from directly hitting the liquid level and causing liquid splashing. When the material input is completed, the electric cylinder is controlled to extend, so that the partition plate moves horizontally to open the lower end of the feed pipe, and the object falls entirely into the liquid. Through the above structure, since the position where the material drops into the liquid is close to the liquid level, it is not easy to generate liquid splashing, the inner wall of the kettle body is not easy to hang with liquid droplets, the utilization rate of the raw material is improved, and the problem that it is difficult to clean after the liquid droplets dry or solidify is avoided.

[0009] Optionally, a slide rail is fixed to the kettle body, a slide bar is fixed to the side wall of the feed pipe, and the slide bar is slidably connected to the slide rail.

[0010] By adopting the above technical solution, through the sliding cooperation of the slide bar and the slide rail, the stability of the lifting of the feed pipe is improved.

[0011] Optionally, two symmetrically arranged C-shaped rods are fixed to the lower end of the feed pipe, and the partition plate is slidably connected to the inner side of the C-shaped rods.

[0012] By adopting the above technical solution, the C-shaped rods function as sliding guides for the partition plate.

[0013] Optionally, a bracket is fixed to the kettle body, a feed hopper is fixed to the bracket, a bellows is connected to the bottom end of the feed hopper, and the lower end of the bellows is connected to the upper end of the feed pipe.

[0014] By adopting the above technical solution, after the height of the feed pipe changes, the bellows expands and contracts adaptively. Since the height of the feed hopper remains unchanged, it is convenient for personnel to put materials through a fixed position.

[0015] Optionally, the inner diameter of the bottom opening of the feed hopper is smaller than the minimum inner diameter of the bellows.

[0016] By adopting the above technical solution, the material falling from the bottom of the feed hopper is not easy to contact the inner wall of the bellows, so the inner wall of the bellows can be kept clean.

[0017] Optionally, a plurality of first guide rods are fixed to the bottom end of the feed hopper, the first guide rods are distributed circumferentially along the bellows, and the first guide rods are in sliding contact with the inner wall of the bellows.

[0018] By adopting the above technical solution, the function of the first guide rods is to support and limit the upper part of the bellows to prevent the upper part of the bellows from being distorted.

[0019] Optionally, a plurality of second guide rods are fixed to the top end of the feed pipe, the second guide rods are distributed circumferentially along the bellows, and the second guide rods are in sliding contact with the outer wall of the bellows.

[0020] By adopting the above technical solution, the function of the second guide rod is to support and restrict the lower part of the bellows, avoiding the distortion and deformation of the lower part of the bellows.

[0021] Optionally, a vertically arranged observation port is provided on the side wall of the kettle body close to the feed pipe, and an observation window is installed at the observation port.

[0022] By adopting the above technical solution, personnel can observe the height of the liquid level in the kettle body and the height position of the lower end of the feed pipe through the observation window.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The height position of the feed pipe can be adjusted, and the position where the material falls into the liquid is close to the liquid level. Therefore, it is not easy to generate liquid splashing, the inner wall of the kettle body is not easy to hang with liquid droplets, the utilization rate of raw materials is improved, and the problem that it is difficult to clean after the liquid droplets dry or solidify is avoided;

[0025] 2. By setting the bellows, when the feed pipe rises and falls, the height of the feed hopper remains unchanged, which is convenient for feeding materials through a fixed position. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following further describes the present application in detail with reference to the accompanying drawings.

[0031] Refer to Figure 1This embodiment discloses a feeding device for a reactor, comprising a reactor body 1 and a feed pipe 2. The feed pipe 2 is vertically slidably connected to the reactor body 1 and is located near the side wall of the reactor body 1 to facilitate material input. It should be noted that the reactor body 1 is mounted adjacent to a multi-story scaffolding. Therefore, personnel can input materials into the feed pipe 2 through the second-story scaffolding or by feeding materials through the equipment without the problem of the feed position being too high to be difficult to input materials.

[0032] A rack 21 is vertically fixed to the outer wall of the feed tube 2. A servo motor 11 and a gear 12 driven by the servo motor 11 are located on the top of the kettle body 1. The servo motor 11 is fixed to the top surface of the kettle body 1, and the gear 12 is fixed to the output end of the servo motor 11. The gear 12 meshes with the rack 21. The servo motor 11 has a built-in braking function, and it remains braked after shutdown. The servo motor 11 drives the gear 12 to rotate, which in turn drives the rack 21 up and down, raising and lowering the rack 21 along with the feed tube 2. Because the servo motor 11 can be precisely controlled, the height of the feed tube 2 can also be precisely controlled.

[0033] The kettle body 1 is fixed with a slide rail 13, and the side wall of the feed pipe 2 is fixed with a slide bar 22, which is slidably connected to the slide rail 13. The slide bar 22 is located on the side of the feed pipe 2 away from the rack 21. Two pairs of slide bars 22 and slide rails 13 are provided. The sliding cooperation between the slide bars 22 and the slide rail 13 improves the stability of the feed pipe 2 when it is raised and lowered. The slide rail 13 can also reverse the force of the gear 12 pressing against the rack 21, ensuring stable operation of the mechanism.

[0034] A vertical observation port 14 is provided on the side wall of the kettle body 1 near the feed pipe 2. An observation window 15 is installed at the observation port 14, and the observation window 15 completely seals the observation port 14. A person observes the lower end position of the feed pipe 2 and the liquid level in the kettle body 1 through the observation window 15, so that after the height of the feed pipe 2 is adjusted, its lower end is as close as possible to the liquid level in the kettle body 1.

[0035] The kettle body 1 is fixed with a bracket 16, and a feed hopper 3 is fixed on the bracket 16. The feed hopper 3 is a funnel-shaped structure with a larger upper part and a smaller lower part. The bottom end of the feed hopper 3 is connected with a bellows 4, and the lower end of the bellows 4 is connected with the upper end of the feed pipe 2. The upper end of the bellows 4 is fixedly connected to the feed hopper 3, and the lower end of the bellows 4 is fixedly connected to the feed pipe 2. When the feed pipe 2 is raised or lowered, the bellows 4 adaptively expands and contracts, and both ends of the bellows 4 are not separated from the feed hopper 3 and the feed pipe 2.

[0036] Reference Figure 2, the feed hopper 3 is coaxially arranged with the corrugated pipe 4, and the inner diameter of the bottom opening of the feed hopper 3 is smaller than the minimum inner diameter of the corrugated pipe 4. The cross-sectional dimensions at various positions in the length direction of the corrugated pipe 4 are different, and the so-called minimum inner diameter refers to the inner diameter at the smallest cross-section of the corrugated pipe 4. With this setting, the material falling from the bottom of the feed hopper 3 is not likely to contact the inner wall of the corrugated pipe 4, so the inner wall of the corrugated pipe 4 can remain clean.

[0037] A plurality of first guide rods 31 are fixed to the bottom end of the feed hopper 3. The first guide rods 31 are distributed along the circumferential direction of the corrugated pipe 4, and the first guide rods 31 are in sliding contact with the inner wall of the corrugated pipe 4. A plurality of second guide rods 23 are fixed to the top end of the feed pipe 2. The second guide rods 23 are distributed along the circumferential direction of the corrugated pipe 4, and the second guide rods 23 are in sliding contact with the outer wall of the corrugated pipe 4. The length directions of the first guide rods 31 and the second guide rods 23 are both in the vertical direction. When the corrugated pipe 4 expands and contracts, the function of the first guide rods 31 is to limit the upper part of the corrugated pipe 4 to prevent the upper part of the corrugated pipe 4 from being distorted; the function of the second guide rods 23 is to limit the lower part of the corrugated pipe 4 to prevent the lower part of the corrugated pipe 4 from being distorted. The first guide rods 31 and the second guide rods 23 work together to keep the corrugated pipe 4 in a vertical state even when the corrugated pipe 4 extends to a longer state, avoiding its distortion, so that when the material passes through, it is not likely to contact the inner wall of the corrugated pipe 4. Preferably, the positions of the first guide rods 31 and the second guide rods 23 are staggered from each other in the circumferential direction of the corrugated pipe 4 to improve the limiting effect on the corrugated pipe 4.

[0038] Refer to Figure 3 , a partition plate 5 is slidably connected to the lower end of the feed pipe 2. The specific sliding connection structure is as follows: two symmetrically arranged C-shaped rods 51 are fixed to the lower end of the feed pipe 2, and the partition plate 5 is slidably connected to the inner side of the C-shaped rods 51. The top surface of the partition plate 5 abuts against the lower end of the feed pipe 2, playing a role in blocking the lower end of the feed pipe 2. An electric cylinder 52 is fixed to the outer wall of the feed pipe 2, and the piston rod end of the electric cylinder 52 is fixed to the partition plate 5. The function of the electric cylinder 52 is to control the movement of the partition plate 5, thereby controlling the on-off of the lower end of the feed pipe 2.

[0039] The implementation principle of a feeding device of a reaction kettle according to an embodiment of the present application is as follows: The operator observes the height of the liquid level in the kettle body 1 through the observation window 15, and then controls the operation of the servo motor 11 to lower the height of the feed pipe 2 so that the lower end of the feed pipe 2 is as close as possible to the liquid level. During this process, the corrugated pipe 4 is stretched and elongated. Since the height of the feed hopper 3 remains unchanged, it is convenient to input the material through a fixed position.

[0040] After the material is put into the feeding hopper 3, the material falls onto the partition plate 5 at the bottom through the feeding pipe 2. The partition plate 5 supports the material to prevent the material from directly hitting the liquid surface and causing liquid splashing. After the material input is completed, control the electric cylinder 52 to extend, so that the partition plate 5 moves horizontally to open the lower end of the feeding pipe 2, and all the objects fall into the liquid. After completion, control the servo motor 11 and the electric cylinder 52 to reverse, so that the feeding pipe 2 and the partition plate 5 move back to their original positions.

[0041] With the above structure, since the position where the material falls into the liquid is close to the liquid surface, it is not easy to generate liquid splashing. The inner wall of the kettle body 1 is not easy to hang with liquid droplets, which improves the utilization rate of raw materials and avoids the problem that it is difficult to clean after the liquid droplets dry or solidify.

[0042] It should be noted that when the main liquid is input into the empty kettle body 1, the way of lowering the feeding pipe 2 can also be used to reduce the liquid splashing in the kettle body 1, thereby reducing the phenomenon of liquid droplets hanging on the wall.

[0043] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
