Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical equipment technology, and more specifically to an anti-clogging chemical reaction vessel. Background Technology
[0002] Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical and food industries. They are pressure vessels used to complete processes such as sulfidation, nitration, hydrogenation, hydrocarbonation, polymerization and condensation, and include reactors, reaction vessels, decomposition vessels and polymerization kettles.
[0003] During operation, reactors typically use a funnel-shaped discharge port, allowing the products inside the reactor to collect along an inclined bottom plate to the discharge port before being discharged. This process is prone to causing sediment to clog the discharge port. Furthermore, especially when the products are slightly viscous, they tend to adhere and accumulate on the inclined plate, causing blockages that are difficult to clean and thus hindering material flow. If not cleaned in time, this will affect the normal operation of the reactor and gradually reduce production efficiency. Current technologies only employ manual or mechanical methods to clean the discharge port, neglecting the cleaning of the inclined bottom plate.
[0004] Therefore, how to provide a chemical reactor that can clean up the accumulated material on the inclined plate at the bottom of the reactor is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the present invention provides an anti-clogging chemical reactor, which solves the problem of blockage caused by the accumulation of materials on the clinker hopper due to stickiness or excessive material by installing a vibration-assisted feeding component at the bottom of the feeding hopper, thereby improving the material conveying efficiency and avoiding the need for manual cleaning of accumulated materials.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A clog-resistant chemical reaction vessel, comprising:
[0008] The vessel body has a feed inlet at the top and a discharge outlet at the bottom, with the discharge outlet fixedly connected to a discharge pipe.
[0009] A feeding funnel is located at the bottom of the vessel body and its outer circumferential edge abuts against the inner circumferential wall of the vessel body. The funnel outlet pipe at the lower part of the feeding funnel is slidably connected to the outlet pipe of the vessel body, so that the feeding funnel can slide back and forth along the axial direction of the vessel body.
[0010] A vibration-assisted feeding assembly includes a drive motor, a drive shaft, and a striking block. The drive motor is fixedly installed on the outer wall of the vessel body. The drive shaft is arranged radially along the discharge pipe, with its first end connected to the drive motor and its second end correspondingly arranged at the bottom of the feeding hopper. One end of the striking block is connected to the outer wall of the second end of the drive shaft and rotates with it, while the other end can abut against the outer wall of the hopper body.
[0011] The elastic telescopic support legs are multiple and are installed vertically at intervals on the bottom end surface of the vessel body, with the top ends of the multiple elastic telescopic support legs abutting and supporting the lower side wall of the vessel body.
[0012] As can be seen from the above solution, this utility model discloses an anti-clogging chemical reactor. The materials generated inside the reactor fall into the feeding funnel and collect at the outlet of the feeding funnel. Normally, the products fall onto the feeding funnel and smoothly pass through its outlet, being discharged from the feeding funnel's discharge pipe without causing displacement of the feeding funnel. The impact block of the vibration-assisted feeding component also does not contact the bottom of the feeding funnel, reducing impact loss between the two. When the products are slightly viscous, they may adhere and accumulate on the feeding funnel. In this case, as the products accumulate, the overall weight of the products and the feeding funnel gradually increases. The increased pressure causes the elastic telescopic legs to extend and retract, causing the feeding funnel to move axially along the reactor body. The downward displacement allows the end face of the striking block to contact the bottom face of the feeding funnel. When the drive motor rotates, it continuously strikes the feeding funnel, causing it to vibrate. This vibration allows the adhered and accumulated material to be discharged from the outlet, effectively solving the problem of material blockage and improving the material cleaning efficiency. Furthermore, the striking block only contacts the bottom face of the feeding funnel when there is material accumulation, avoiding damage to both structures due to the continuous action of the striking block on the feeding funnel. This reduces the frequency of equipment maintenance and replacement, and lowers maintenance costs.
[0013] Furthermore, the elastic telescopic support leg includes a fixed support tube, a spring, and a sliding support leg. The lower end of the fixed support tube is vertically fixed to the bottom of the vessel body. The spring is coaxially located inside the fixed support tube. The sliding support leg slides from the upper end of the fixed support tube inside it, and its lower end is fixedly connected to the upper end of the spring. Its upper end abuts against and is fixed to the bottom end face of the feeding funnel.
[0014] The beneficial effects of adopting the above technical solution are: the elastic telescopic support leg can automatically adjust the support height according to the weight and position changes of the feeding funnel, ensuring that the feeding funnel remains stable under different working conditions and avoiding equipment shaking or blockage caused by unstable support; it can also work in conjunction with the vibration-assisted feeding component, and further enhance the vibration effect of the feeding funnel through the elastic extension and contraction of the spring, thereby more effectively preventing material accumulation and blockage.
[0015] Furthermore, the striking block is a rubber block.
[0016] The beneficial effects of adopting the above technical solution are: the rubber material has good elasticity, which can effectively buffer the impact force during the impact process, avoid hard collision with the bottom of the feeding hopper, thereby reducing the risk of equipment wear and damage, preventing scratches, dents or other mechanical damage caused by long-term hard contact, and extending the service life of the equipment.
[0017] Furthermore, it also includes a material dispersion component, which includes a second drive motor, a rotating shaft, and dispersion blades. The second drive motor is fixedly installed on the top of the vessel body, and the rotating shaft is rotatably installed on the top of the vessel body along its axial direction. One end of the rotating shaft is connected to the drive end of the second drive motor, and the dispersion blades are in multiple sets and are installed at intervals along the axial direction of the rotating shaft on its outer side wall.
[0018] The beneficial effects of adopting the above technical solution are: the dispersing blades shear, impact, and disperse the material through high-speed rotation, effectively breaking up material agglomeration and achieving a more uniform mixing effect. This design is particularly suitable for high-viscosity or easily agglomerated materials, and can significantly improve mixing efficiency.
[0019] Furthermore, it also includes a screw feeding mechanism, which includes a drive shaft and screw blades. The drive shaft is installed inside the funnel discharge pipe along its axial direction. One end of the drive shaft is fixedly connected to one end of the rotating shaft and rotates together with it. The screw blades are located inside the funnel discharge pipe and are fixedly wound around the outer wall of the drive shaft.
[0020] The beneficial effects of adopting the above technical solution are: the spiral blades rotate continuously in the discharge pipe of the funnel, which can play a role in stirring and pushing the material, preventing the material from accumulating or clumping in the discharge pipe, thereby effectively avoiding equipment failure and production stoppage caused by material blockage; even if a slight blockage occurs in some cases, the continuous rotation of the spiral blades and the squeezing effect on the material can help to clear the blockage, allowing the material to continue to be transported smoothly, reducing the frequency and workload of manual cleaning.
[0021] Furthermore, the material dispersion assembly also includes connecting rods and scrapers. There are two connecting rods, both of which are installed radially and vertically on their outer side walls along the rotation axis, and the two connecting rods are arranged in the same straight line. There are two scrapers, each fixed to one end of the two connecting rods away from the rotation axis. Both scrapers are arranged axially along the vessel body, and one end face of each scraper abuts against the inner side wall of the vessel body.
[0022] The beneficial effects of adopting the above technical solution are: the scraper is in close contact with the inner wall of the vessel, which can continuously scrape off the material adhering to the inner wall during the stirring process, prevent the material from scaling or hardening due to long-term residence, significantly reduce the accumulation of material on the inner wall of the vessel, thereby reducing the cleaning frequency of the equipment and saving time and resources.
[0023] Furthermore, the side face of the scraper that abuts against the inner wall of the vessel is an arc-shaped surface.
[0024] The beneficial effects of adopting the above technical solution are: the arc-shaped scraper can fit closely with the inner wall of the reactor (usually cylindrical or arc-shaped), reducing gaps, thereby more effectively scraping off the material on the inner wall, avoiding material residue, significantly improving the cleaning effect of the reactor, while reducing equipment wear, noise and maintenance costs.
[0025] Furthermore, it also includes a limiting plate, both ends of which are fixed to the inner sidewall of the vessel body, and one side of the limiting plate is parallel to and spaced apart from the top surface of the feeding funnel.
[0026] The beneficial effects of adopting the above technical solution are: by fixing the limiting plate to the inner side wall of the vessel and arranging it parallel to the top surface of the feeding funnel, the limiting plate can effectively limit the excessive axial movement of the feeding funnel and ensure its stable operation in the predetermined position; by limiting the displacement of the feeding funnel, the limiting plate can prevent it from colliding or rubbing with other components (such as dispersion components), thereby reducing equipment wear and the risk of failure.
[0027] Furthermore, the limiting plate is arranged radially along the vessel body, and bearings are provided on both ends of the plate corresponding to the rotating shaft. One end of the rotating shaft passes through the inner ring of the bearing and is connected to it for transmission.
[0028] The beneficial effects of adopting the above technical solution are: the limiting plate passes through the axis of the rotating shaft and supports the rotating shaft through the bearing, which can ensure that the rotating shaft always maintains accurate axial positioning during operation and avoid vibration and wear caused by axial offset or shaking.

Detailed Implementation
[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] This utility model discloses an anti-clogging chemical reactor, including a reactor body 1. The reactor body 1 has a feed inlet 11 at its top and a discharge outlet at its bottom, which is fixedly connected to a reactor body discharge pipe 12. A feeding funnel 2 is installed at the bottom of the reactor body 1. The outer circumferential edge of the funnel body 22 abuts against the inner circumferential wall of the reactor body 1. The funnel discharge pipe 21 at the bottom of the feeding funnel 2 is coaxially and slidably connected within the reactor body discharge pipe 12, allowing the feeding funnel 2 to slide back and forth along the axial direction of the reactor body 1. A vibration-assisted feeding assembly 3 is installed at the bottom of the reactor body 1. The feeding assembly 3 includes a drive motor 31, a drive shaft 32, and a striking block 33. The drive motor 31 is fixedly installed on the outer wall of the vessel body 1. The drive shaft 32 is arranged radially along the discharge pipe 12 of the vessel body, and its first end is connected to the drive motor 31. The second end is correspondingly arranged at the bottom of the feeding funnel 2. One end of the striking block 33 is connected to the second end of the drive shaft 32, and the other end can abut against the outer wall of the funnel body 22. Elastic telescopic support legs 4 are vertically installed at intervals on the inner bottom end surface of the vessel body 1. There are multiple elastic telescopic support legs 4, and their top ends abut against and support the lower side wall of the funnel body 22.
[0036] In a specific embodiment of this utility model regarding the elastic telescopic support leg 4, the elastic telescopic support leg 4 includes a fixed support pipe 41, a spring, and a sliding support leg 42. The lower end of the fixed support pipe 41 is vertically fixed to the bottom of the vessel body 1. The spring is coaxially located inside the fixed support pipe 41. The sliding support leg 42 slides from the upper end of the fixed support pipe 41 inside it, and its lower end is fixedly connected to the upper end of the spring. Its upper end abuts against and is fixed to the bottom end face of the feeding funnel 2. The elastic telescopic support leg 4 can automatically adjust the support height according to the weight and position changes of the feeding funnel 2, ensuring that the feeding funnel 2 remains stable under different working conditions and avoiding equipment shaking or blockage caused by unstable support. It can also work in conjunction with the vibration-assisted feeding 3 component, further enhancing the vibration effect of the feeding funnel through the elastic extension and contraction of the spring, thereby more effectively preventing material accumulation and blockage.
[0037] In the above embodiment, the striking block 33 is a rubber block. Rubber material has good elasticity, which can effectively buffer the impact force during the striking process, avoid hard collision with the bottom of the feeding hopper, thereby reducing the risk of equipment wear and damage, preventing scratches, dents or other mechanical damage caused by long-term hard contact, and extending the service life of the equipment.
[0038] In another embodiment of this utility model, a material dispersion component 5 is further included. The material dispersion component 5 includes a second drive motor 51, a rotating shaft 52, and dispersion blades 53. The second drive motor 51 is fixedly installed on the outer top of the vessel body 1. The rotating shaft 52 is rotatably installed on the inner top of the vessel body 1 along its axial direction. One end of the rotating shaft 52 is connected to the drive end of the second drive motor 51. Multiple sets of dispersion blades 53 are spaced apart along the axial direction of the rotating shaft 52 on its outer side wall. The dispersion blades 53 shear, impact, and disperse the material through high-speed rotation, effectively breaking up material agglomeration and achieving a more uniform mixing effect. This design is particularly suitable for high-viscosity or easily agglomerated materials, significantly improving mixing efficiency.
[0039] In another embodiment of this utility model, a screw feeding mechanism 6 is also included. The screw feeding mechanism 6 includes a drive shaft 61 and a screw blade 62. The drive shaft 61 is installed inside the funnel discharge pipe 21 along its axial direction. One end of the drive shaft 61 is fixedly connected to one end of the rotating shaft 52 and rotates together with it. The screw blade 62 is located inside the funnel discharge pipe 21 and is fixedly wound around the outer wall of the drive shaft. The screw blade 62 rotates continuously inside the funnel discharge pipe 21, which can stir and push the material, preventing the material from accumulating or clumping in the discharge pipe, thereby effectively avoiding equipment failure and production stoppage caused by material blockage. Even if a slight blockage occurs in some cases, the continuous rotation of the screw blade 62 and the squeezing action on the material can help to clear the blockage and allow the material to continue to be transported smoothly, reducing the frequency and workload of manual cleaning.
[0040] In the above embodiment, the material dispersion assembly 5 further includes connecting rods 54 and scrapers 55. Two connecting rods 54 are mounted radially and perpendicularly to their outer side walls along the rotation shaft 52. Two scrapers 55 are fixed to the ends of the two connecting rods 54 away from the rotation shaft 52. Both scrapers 55 are arranged axially along the vessel body 1, with one end face abutting against the inner side wall of the vessel body 1. The scrapers 55 are in close contact with the inner wall of the vessel body 1, continuously scraping away material adhering to the inner wall during stirring, preventing scaling or hardening of the material due to prolonged residence, significantly reducing material accumulation on the inner wall of the vessel body 1, thereby reducing the equipment cleaning frequency and saving time and resources.
[0041] In the above embodiment, the end face of the scraper 55 that abuts against the inner wall of the vessel body 1 is an arc-shaped surface. The arc-shaped scraper 55 can fit tightly against the inner wall of the vessel body 1, reducing gaps and thus more effectively scraping off the material on the inner wall, avoiding material residue, significantly improving the cleaning effect of the reactor, while reducing equipment wear, noise and maintenance costs.
[0042] Other embodiments of this utility model also include a limiting plate 7, both ends of which are fixed to the inner sidewall of the vessel body 1, and one side of the limiting plate 7 is parallel to and spaced apart from the top surface of the feeding funnel 2. By fixing the limiting plate 7 to the inner sidewall of the vessel body 1 and arranging it parallel to the top surface of the feeding funnel 2, the limiting plate 7 can effectively limit the excessive axial movement of the feeding funnel 2, ensuring its stable operation in a predetermined position; by limiting the displacement of the feeding funnel 2, the limiting plate 7 can prevent it from colliding or rubbing against the dispersing components, thereby reducing equipment wear and the risk of failure.
[0043] In the above embodiment, the limiting plate 7 is arranged radially along the vessel body 1, and bearings 71 are provided on both ends of the plate corresponding to the rotating shaft 52. One end of the rotating shaft 52 passes through the inner ring of the bearing 71 and is connected to it for transmission. The limiting plate 7 passes through the axis of the rotating shaft 52 and supports the rotating shaft 52 through the bearings 71, which can ensure that the rotating shaft 52 always maintains accurate axial positioning during operation and avoid vibration and wear caused by axial offset or shaking.
[0044] The working principle of this anti-clogging chemical reactor is as follows:
[0045] The reactants enter the vessel through the inlet and are first dispersed by the material dispersion component to ensure uniform distribution and full reaction. The products fall into the feeding hopper. When the conveying is smooth, the products do not accumulate, and the pressure on the feeding hopper is low, preventing significant downward displacement. This ensures that the impact block of the vibration-assisted feeding component does not come into contact with the lower end of the feeding hopper, completing the smooth conveying process. When there is too much product or when it is viscous and partially accumulates, the elastic telescopic legs retract after reaching a certain weight pressure, and the feeding hopper descends along with it until the impact block repeatedly strikes the bottom end of the hopper, causing the feeding hopper to vibrate and convey the accumulated material to the hopper's discharge pipe. Then, the spiral blades carry the material out of the vessel, further improving the discharge efficiency at the vessel outlet.
[0046] In addition, a set of scrapers is installed inside the vessel, which rubs against the inner wall of the vessel to remove all the material adhering to the inner wall of the vessel, preventing the material from scaling or hardening due to prolonged residence.
[0047] Therefore, the chemical reactor of this utility model, by setting up a vibration-assisted feeding component and a feeding funnel that can move up and down, can discharge the adhered and accumulated material from the discharge port through vibration feeding, effectively solving the material blockage problem and improving the material cleaning efficiency. In addition, the impact block only contacts the bottom surface of the feeding funnel when there is product accumulation, avoiding damage to the structure of both due to the continuous action of the impact block on the feeding funnel, reducing the frequency of equipment maintenance and replacement, and lowering maintenance costs.
