Description

Technical Field

[0001] This invention relates to the field of catalytic reaction technology, and in particular to a self-cleaning, high-efficiency catalytic device for reaction chambers. Background Technology

[0002] Currently, in the fields of chemical engineering, environmental protection, and materials synthesis, catalytic reaction steps are required to catalyze materials. Catalytic reactions are the core process for achieving material conversion, pollutant degradation, and product synthesis. Currently, reaction devices are used as the core carriers for catalytic reactions. However, existing reaction chamber catalytic devices generally have many technical shortcomings, making it difficult to meet the demands for efficient, continuous, and convenient production. Specific deficiencies are as follows: First, the sealing cover is cumbersome to install and remove. Existing devices mostly use multiple sets of bolts to lock the sealing cover individually. During installation, positioning is troublesome and a wrench is needed to remove the bolts. The operation of the sealing cover is time-consuming and laborious, which greatly affects the convenience of maintenance of internal catalytic components, catalyst replacement and cleaning of the tank cavity, increasing maintenance costs and downtime. Secondly, the catalytic efficiency is low. The existing equipment has a simple material stirring structure, which easily leads to material stratification and retention. The contact area between the catalyst and the reactants is limited, and the catalyst is mostly fixed, making it difficult to achieve up-and-down reciprocating motion, resulting in a slow catalytic reaction rate and poor reaction uniformity. In addition, reaction products, unreacted materials, and catalyst residues are prone to adhering to the inner wall of the reaction vessel. Long-term accumulation will reduce the heat transfer efficiency of the chamber and inhibit the activity of the catalyst. The cleaning structure installed in the existing equipment is prone to wear after long-term use, which will create a gap between the cleaning structure and the inner wall of the vessel, thereby causing the cleaning structure to lose its cleaning effect and affecting the catalytic quality of the product. Summary of the Invention

[0003] This invention relates to a self-cleaning, high-efficiency catalytic device for reaction chambers. During operation, the catalyst is placed on a catalytic mesh, and the material is injected into the reaction tank. A sealing cap is installed using a positioning rod and automatically locked in place by a locking structure. Starting an electric motor drives a rotating sleeve, mixing frame, and rotating rod synchronously via gear transmission. The rotating catalytic mesh, combined with material stirring and dispersion, ensures a thorough catalytic reaction. The friction sleeve drives the rotating rod to reciprocate up and down, further improving catalytic uniformity. Simultaneously, a scraper and scraping ring adaptively conform to the inner wall of the tank, rotating to scrape away residue, achieving simultaneous self-cleaning during the reaction. After operation, the sealing cap can be unlocked via a control rope, facilitating catalytic component maintenance and chamber cleaning. The entire unit achieves integrated operation of mixing, catalysis, and self-cleaning with a single power source.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. Based on the described 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.

[0024] Example 1: Please refer to Figures 1 to 10 : This invention proposes a self-cleaning, high-efficiency catalytic device for a reaction chamber, comprising: a reaction vessel 100, a set of support legs at the bottom of the reaction vessel 100, and a fixedly connected sealing cover 200 installed at the upper end of the reaction vessel 100. The sealing cover 200 is configured as a single unit. A set of first positioning rods 110 arranged in a circular array are fixedly provided at the upper end of the reaction vessel 100. A set of docking holes corresponding to the first positioning rods 110 are opened at the edge of the sealing cover 200. The first positioning rods 110 pass through the interior of the docking holes. The first positioning rods 110 enable rapid alignment and installation of the sealing cover 200 with the reaction vessel 100, preventing installation misalignment of the sealing cover 200 and ensuring the sealing performance of the sealing cover 200 and the reaction vessel 100. In at least one embodiment, a set of locking rods 310 arranged in a circular array are installed on the upper end of the sealing cover 200. The outer surface of each locking rod 310 is provided with a fixedly connected positioning block 320. A sliding hole is formed inside the first positioning rod 110, and one side of the locking rod 310 passes through the sliding hole. A set of fixedly connected positioning sleeves 210 are provided on the upper end face of the sealing cover 200, and the other side of the locking rod 310 passes through the positioning sleeve 210. A support spring is installed on the outer side of the locking rod 310, positioned between the positioning block 320 and the positioning sleeve 210. The support spring pushes the locking rod 310... The locking rod 310 automatically engages with the first positioning rod 110. A through hole is provided inside the positioning block 320, through which a control rope 350 is inserted. The control rope 350 connects a set of locking rods 310 in series. The positioning sleeve 210, in conjunction with the positioning block 320, guides and limits the locking rods 310, ensuring smooth sliding. A support spring enables the locking rods 310 to automatically engage with the first positioning rod 110, quickly locking the sealing cover 200 to the reaction vessel 100. No manual operation of each locking rod 310 is required, making operation convenient. The control rope 350 connecting a set of locking rods 310 allows for the connection of multiple sets of locking rods. Synchronous unlocking of 310 facilitates quick disassembly of the sealing cover 200, providing convenience for catalytic component maintenance and chamber cleaning, and solving the problem of cumbersome disassembly and assembly of the sealing cover 200 in existing devices. A slidingly connected push rod 330 is installed at the upper end of the sealing cover 200, and a support spring is installed on the outer side of the push rod 330. The support spring pushes the push rod 330 to return to its original position, so that a set of locking rods 310 can effectively lock the sealing cover 200 automatically. A fixedly connected threaded sleeve is provided on one side of the push rod 330, and a threaded positioning bolt 340 is installed inside the threaded sleeve. The positioning bolt 340 and the threaded bolt... The thread pitch of the threaded connecting sleeve is processed according to actual needs. One side of the threaded connecting sleeve is in slight contact with the control rope 350. The locking rod 310, positioning block 320, push rod 330, positioning bolt 340, and control rope 350 cooperate to form a locking structure 300. Pushing the push rod 330 inward causes the threaded connecting sleeve to push the control rope 350. The control rope 350 pulls a set of locking rods 310 inward, realizing the synchronous unlocking of a set of locking rods 310. Rotating the positioning bolt 340 will assist in locking the push rod 330 that is pressed inward, thus completing the quick unlocking of the sealing cover 200, which is labor-saving. In at least one embodiment, a stabilizing plate 220 is fixedly connected to the upper end face of the sealing cover 200. The stabilizing plate 220 has an L-shaped structure, and there is only one stabilizing plate 220. An electric motor 410 is fixedly connected to the upper end of the stabilizing plate 220. A rotating hole is opened in the middle of the sealing cover 200, and a rotating sleeve 420 is rotatably connected inside the rotating hole. A driven gear is fixedly connected to the outer side of the rotating sleeve 420. A drive gear is installed at the bottom of the drive shaft of the electric motor 410. The drive gear and the driven gear mesh, and the gear stably transmits the power of the electric motor 410 to the rotating sleeve 420. The electric motor 410 drives the rotating sleeve 420 to rotate stably, providing stable power for subsequent mixing, catalysis, and self-cleaning operations. A fixedly connected mixing frame 430 is installed on the outer side of the reaction tank 100. When the rotating sleeve 420 rotates, it drives the mixing frame 430 to rotate. A set of discharge holes is opened at the bottom of the rotating sleeve 420. A set of discharge holes is opened inside and on the side of the mixing frame 430. The discharge holes of the mixing frame 430 and the rotating sleeve 420 are connected. The mixing frame 430 rotates with the rotating sleeve 420. The mixing frame 430 fully stirs and mixes the reactants in the reaction tank 100, avoids material stratification, and increases the contact area between the material and the catalyst. The connected discharge holes allow the reactants or catalyst to enter the mixing frame 430 from the rotating sleeve 420 and be evenly dispersed to various areas of the reaction tank 100 through the side discharge holes of the mixing frame 430, further improving the mixing uniformity and solving the defects of uneven material mixing and low catalytic efficiency in existing devices. In at least one embodiment, a slidably connected rotating rod 440 is installed at the bottom of the rotating sleeve 420. The bottom of the rotating sleeve 420 has a set of positioning protrusions 4201 arranged in a circular array. The positioning protrusions 4201 have an arc structure. A set of sliding grooves corresponding to the rotating sleeve 420 and the positioning protrusions 4201 are formed inside the rotating rod 440. The bottom of the rotating sleeve 420 and the positioning protrusions 4201 extend into the sliding grooves. The positioning protrusions 4201 cooperate with the sliding grooves to achieve synchronous rotation of the rotating sleeve 420 and the rotating rod 440, while allowing the rotating rod 440 to slide up and down along the rotating sleeve 420. A fixedly connected catalyst mesh 450 is installed on the outer side of the rotating rod 440. The electric motor 410, rotating sleeve 420, mixing frame 430, positioning protrusions 4201, rotating rod 440, and catalyst mesh 450 cooperate to form a reaction catalysis mechanism 400. A fixedly connected friction sleeve 120 is provided at the bottom of the reaction tank 100. The bottom of the rotating rod 440 extends into the interior of the friction sleeve 120. The catalyst screen 450 rotates with the rotating rod 440, increasing the contact area between the catalyst and the reactants, thereby improving the catalytic reaction rate and reaction uniformity. The friction sleeve 120 provides bottom support and limit for the rotating rod 440, preventing it from shifting during rotation and ensuring the smooth rotation of the catalyst screen 450. It also provides a guide for the rotating rod 440 to slide up and down. A set of circular arc grooves arranged in a ring array are provided at the bottom of the rotating rod 440. A set of extrusion protrusions are provided inside the friction sleeve 120, corresponding to the arc grooves and extending into the interior of the arc grooves. The extrusion protrusions cooperate with the arc grooves. By rotating the rotating rod 440, the extrusion protrusions exert an up-and-down extrusion force on the arc grooves, causing the rotating rod 440 to be driven by the force to move the catalyst screen 450 up and down along the rotating sleeve 420. This allows the catalyst and reactants to fully contact each other from different heights, further improving catalytic efficiency while reducing energy consumption and manufacturing costs. In at least one embodiment, a set of movably connected scrapers 500 are installed inside the reaction vessel 100. Two vertically distributed second positioning rods 510 are provided on the inner side of the scrapers 500. A sliding hole is opened at the upper and lower positions of the mixing frame 430, and the second positioning rods 510 pass through the interior of the sliding holes. A fixedly connected extrusion block 5101 is provided on the outer side of the second positioning rods 510. The extrusion block 5101 has an inclined block structure. An inclined surface is provided inside the sliding hole of the mixing frame 430, corresponding to the extrusion block 5101. A set of support springs is installed on the outer side of the second positioning rods 510, elastically supporting the scrapers 500 outwards. The outer side of the scrapers 500 is in slight contact with the inner wall of the reaction vessel 100. The support springs ensure that the scrapers 500 always elastically conform to the inner wall of the reaction vessel 100. When the mixing frame 430 rotates, the inclined surface of the sliding hole of the mixing frame 430 interacts with the extrusion block 5101, driving the scrapers 500 along the second positioning rods 5101. The positioning rod 510 moves slightly radially and laterally, cooperating with the rotation of the mixing frame 430, to achieve all-round wiping and cleaning of the inner wall of the reaction tank 100 by the scraper 500. It removes the reaction products and residues adhering to the inner wall in real time, avoiding the accumulation of residues that affect heat transfer and catalytic efficiency. It eliminates the need for manual shutdown for cleaning, improving the continuous production efficiency of the device. A scraping ring 520 is rotatably connected to the outer side of the rotating sleeve 420 and the friction sleeve 120, respectively. The scraping ring 520 is installed between a set of scrapers 500. A set of sliding grooves is opened on the side of the scraping ring 520. One side of the scraper 500 extends into the interior of the sliding groove. When the scraper 500 rotates, it drives the scraping ring 520 to rotate synchronously. The scraping ring 520 can scrape the middle position of the inner wall of the reaction tank 100, which, together with the scraper 500, improves the self-cleaning effect. At the same time, the scraping ring 520 can limit the scraper 500, preventing the scraper 500 from deviating and avoiding cleaning dead corners on the inner wall of the reaction tank 100.

[0025] Example 2, based on Example 1, such as Figures 1-8 As shown, a feeding channel can be added inside the rotating sleeve 420, which is connected to the discharge hole of the rotating sleeve 420. At the same time, a feeding interface is added to the upper end of the sealing cover 200, which is connected to the feeding channel to achieve precise delivery of reactants and catalysts.

[0026] The working principle of this embodiment: When using the catalytic device, first press the push rod 330 inward to move a set of locking rods 310 inward, tighten the positioning bolts 340 to complete the positioning of the locking rods 310, and align the sealing cover 200 with the first positioning rod 110 and install it on the upper end of the reaction vessel 100. Then loosen the positioning bolts 340, and the support spring in the locking structure 300 pushes the locking rod 310 to automatically engage in the sliding hole of the first positioning rod 110, completing the locking and fixing of the sealing cover 200. Then rotate the positioning bolts 340 again to lock the position of the push rod 330 to ensure that the sealing cover 200 is firmly locked.

[0027] The reactants are injected into the reaction vessel 100. The electric motor 410 is started to drive the gear to rotate. The gear meshing drives the rotating sleeve 420 to rotate stably. The rotating sleeve 420 cooperates with the sliding groove through the positioning protrusion 4201, which drives the rotating rod 440 to rotate synchronously, thereby driving the catalyst screen 450 and the mixing rack 430 to rotate.

[0028] When the mixing rack 430 rotates, it stirs the reactants. At the same time, the rotating sleeve 420 and the discharge hole of the mixing rack 430 disperse the materials and catalyst evenly. The rotating catalytic mesh 450 ensures that the catalyst and materials are in full contact, thus initiating the catalytic reaction.

[0029] When the rotating rod 440 rotates, the extrusion protrusion of the friction sleeve 120 and the arc groove of the rotating rod 440 extrude against each other, causing the rotating rod 440 to move up and down repeatedly, further improving the catalytic contact effect.

[0030] At the same time, when the mixing frame 430 rotates, the inclined surface of the sliding hole of the mixing frame 430 presses the extrusion block 5101 on the second positioning rod 510. With the elastic action of the support spring, the scraper 500 moves radially and rotates against the inner wall of the reaction tank 100 to wipe and clean the inner wall, thus completing real-time self-cleaning during the material reaction process.

[0031] After the catalytic reaction of the material is completed, the electric motor 410 is turned off, the positioning bolt 340 is loosened, and the push rod 330 is pressed to drive a set of locking rods 310 to unlock synchronously through the control rope 350. The sealing cover 200 is then removed, and the catalytic mesh 450 can be maintained and replaced. At the same time, the reaction tank 100 can be cleaned. The whole machine achieves integrated collaborative operation of catalysis, mixing and self-cleaning through a single electric motor 410. It has a compact structure and a high degree of automation, effectively solving the defects of existing equipment such as inconvenient cleaning, low catalytic efficiency and cumbersome maintenance.
