A three-way catalyst feedstock processing apparatus

Abstract

This invention relates to the field of three-way catalyst processing technology and discloses a three-way catalyst raw material processing device, including a support unit. The support unit includes a stirring shell and a sealing cover, with the end faces of the stirring shell and the sealing cover fitting together. A drive unit, a preliminary stirring unit, and a mixing stirring unit are installed inside the stirring shell and the sealing cover. In this invention, the mixing stirring unit, during the rotation of the drive shaft, drives the bottom drive bevel gear to rotate. The drive bevel gear's side wall meshes with a driven bevel gear, which in turn drives the connected ring and arc-shaped support to rotate synchronously. The rotation of the arc-shaped support causes the connecting shaft and the positioning rod to rotate alternately, thereby stirring the raw material passing through the preliminary stirring unit. This results in more thorough mixing. Furthermore, the raw material passing through the preliminary stirring unit is fed slowly, reducing the occurrence of uneven mixing caused by simultaneous feeding. This method is suitable for widespread application and promotion.

Description

Technical Field

[0001] This invention belongs to the field of three-way catalyst processing technology, specifically, it relates to a three-way catalyst raw material processing equipment. Background Technology

[0002] Three-way catalytic converters operate within a closed-circuit system equipped with a sensor. They convert harmful gases emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. During the processing of three-way catalytic converters, a mixing device is required to mix various materials together. Existing mixing devices for processing three-way catalytic converters typically select a container for mixing. After the three-way catalytic converter is mixed inside the container, it is discharged outside the container.

[0003] However, during the preparation process, it was found that when all the raw materials were poured into the mixing container at once during the stirring and feeding process, it was easy to cause uneven mixing of the upper and lower layers of raw materials. However, if the materials were stirred and fed in batches, the feed port needed to be opened intermittently to add raw materials to the inside in batches, which was more complicated to operate and had low mixing efficiency.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0014] In a preferred embodiment of the present invention, insert rods are welded at the four corners of the cross-shaped connecting bracket, and baffles are movably inserted into the insert rods. The baffles have sieve holes and a through hole at the center, through which the drive shaft is movably passed. A limiting plate is installed at the end of the insert rods, and the limiting plate overlaps the bottom of the baffles.

[0015] In a preferred embodiment of the present invention, an auxiliary component is installed on the baffle. The auxiliary component includes a scraper that is attached to the baffle.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0042] Example 1:

[0043] like Figures 1 to 11 As shown, a three-way catalyst raw material processing device includes a support unit 100. The support unit 100 includes a stirring shell 101 and a sealing cover 103. The end faces of the stirring shell 101 and the sealing cover 103 are fitted together. A drive unit 200, a preliminary stirring unit 300, and a mixing stirring unit 400 are installed inside the stirring shell 101 and the sealing cover 103. The drive unit 200 includes a drive motor 201. The housing of the drive motor 201 is fixedly installed on the top of the sealing cover 103.

[0044] The preliminary stirring unit 300 includes a drive shaft 301, the top of which is connected to the output shaft of a drive motor 201. Four sets of first supports 3011 and second supports 3012 are symmetrically arranged on the sidewalls of the drive shaft 301. Several stirring rods 3013 are rotatably mounted on each set of first supports 3011 and second supports 3012, and the stirring rods 3013 are alternately distributed. A gear shaft 302 is movably mounted at the end of each set of first supports 3011 and second supports 3012. Several guide plates 3021 are mounted on the sidewalls of the gear shaft 302, and a drive gear 3022 is mounted on the top of the gear shaft 302. The system is equipped with a preliminary stirring unit, in which the transmission shaft inside the preliminary stirring unit can be driven by the drive unit. The rotation of the transmission shaft can drive the first and second supports to rotate synchronously, while the central stirring rod can mix with the raw materials. With continuous stirring, the stirring efficiency can be improved. During the stirring process, the guide plate is rotated by the cooperation of the drive gear and the guide rack, thereby conveying the raw materials on the side wall to the center, which facilitates stirring. During the stirring process, the raw materials that have reached a certain size enter the mixing and stirring unit through the screen holes of the baffle, which also serves the purpose of screening.

[0045] The mixing unit 400 includes a ring 401. Several arc-shaped supports 402 are arranged around the sidewalls of the ring 401. A mixing rod 4021 is mounted at the bottom of each arc-shaped support 402. A positioning shaft 403 is horizontally mounted in the central cavity of each arc-shaped support 402. Several positioning rods 4031 are mounted on the positioning shaft 403. The positioning rods 4031 and mixing rods 4021 are staggered. The sidewalls of the ring 401 are connected to the bottom of the drive shaft 301 via bevel gears. With this mixing unit, the rotation of the drive shaft drives the bottom drive bevel gear to rotate. The drive bevel gear's sidewall meshes with a driven bevel gear, causing the connected ring and arc-shaped supports to rotate synchronously. The rotation of the arc-shaped supports causes the connecting shaft and positioning rods to rotate alternately, thus mixing the raw materials passing through the preliminary mixing unit more thoroughly. Furthermore, the raw materials passing through the preliminary mixing unit are fed slowly, reducing the occurrence of uneven mixing caused by simultaneous feeding.

[0046] like Figures 1 to 11As shown, in a specific embodiment, a maintenance door 1011 is movably hinged to the side wall of the stirring shell 101. A sealing gasket is provided on the outer edge of the maintenance door 1011. Mounting ears 1031 are installed on the side walls of both the stirring shell 101 and the sealing cover 103, with two mounting ears 1031 fitting together. Bolts and nuts mounted on the bolts are movably inserted inside the mounting ears 1031, and sealing washers are installed between the mounting ears 1031. Four support legs 1012 are installed at the bottom of the stirring shell 101, with reinforcing ribs ring-shaped on the four support legs 1012. A discharge pipe 102 is connected to the bottom of the stirring shell 101, and a mechanical valve 1021 is installed on the discharge pipe 102. The height of the discharge pipe 102 is lower than the height of the support legs 1012. The inspection door 1011 facilitates future maintenance, while the mechanical valve 1021 allows for the opening and closing of the discharge pipe 102, facilitating material unloading. The sealing gasket improves the device's sealing performance and reduces dust leakage during the mixing process.

[0047] like Figures 1 to 11 As shown, furthermore, the output shaft of the drive motor 201 movably passes through the sealing cover 103, and a rectangular shaft 2011 is installed at the end of the output shaft. A cross-shaped connecting bracket 203 is bolted and fixed inside the stirring shell 101. A collar 202 is movably mounted on the cross-shaped connecting bracket 203, and a rectangular inner cavity 2021 is opened inside the collar 202. The rectangular shaft 2011 is movably inserted into the rectangular inner cavity 2021, and the rectangular shaft 2011 and the rectangular inner cavity 2021 are compatible in size. First, the operator needs to open the sealing cover 103, pour a certain amount of three-way catalyst raw material into the stirring shell 101, and reseal the stirring shell 101 through the sealing cover 103. During the sealing process, the rectangular shaft 2011 at the bottom of the sealing cover 103 needs to be inserted into the rectangular inner cavity 2021. Next, the user starts the drive motor 201, which drives the rectangular shaft 2011 to rotate. The rectangular shaft 2011 is inserted into the collar 202, at which point the collar 202 and the drive shaft 301 begin to rotate.

[0048] Example 2:

[0049] The difference between the above embodiments and this embodiment is that:

[0050] like Figures 1 to 11As shown, a circular groove is provided at the bottom of the cross connecting bracket 203, and a guide rack 3023 is provided inside the groove. The guide rack 3023 is adapted to the drive gear 3022. A drive shaft 301 is movably provided at the bottom of the cross connecting bracket 203, and the drive shaft 301 movably passes through the cross connecting bracket 203. The end of the drive shaft 301 is fixedly connected to the rotation center of the collar 202. A first bracket 3011 and a second bracket 3012 are installed on the side wall of the drive shaft 301. The first bracket 3011 and the second bracket 3012 begin to move around a circle, thereby mixing and stirring the internal raw materials. During the continuous rotation of the first bracket 3011 and the second bracket 3012, the drive gear 3022 at the end of the first bracket 3011 and the second bracket 3012 intermittently contacts the guide rack 3023. Through the limiting of the guide rack 3023, the drive gear 3022 is finally driven to start rotating. After the drive gear 3022 rotates, it will drive the gear shaft 302 at the bottom to start rotating. The guide plate 3021 on which the gear shaft 302 is installed starts to rotate synchronously. Since the guide plate 3021 is installed on the side wall, when the guide plate 3021 rotates, it can drive the raw materials in the center and the raw materials on the side wall to mix, thereby improving the mixing effect and completing the initial mixing purpose.

[0051] like Figures 1 to 11 As shown in the specific embodiment, insert rods 304 are welded at the four corners of the cross-shaped connecting bracket 203. Baffles 303 are movably inserted into the insert rods 304. The baffles 303 have sieve holes 3031 and a through hole 3032 at their center, through which the drive shaft 301 passes. A limiting plate 3041 is installed at the end of the insert rods 304, overlapping the bottom of the baffles 303. The insert rods 304 primarily function as limiting devices, ensuring that the baffles 303 can only move up and down. During this up-and-down movement, the limiting plate 3041 at the bottom fixes the lowest descending position.

[0052] like Figures 1 to 11As shown, further, an auxiliary component 500 is installed on the baffle 303. The auxiliary component 500 includes a scraper 501, which is attached to the baffle 303. A guide rail 5013 is provided on the baffle 303, and the scraper 501 slides on the guide rail 5013. A connecting seat 5011 is symmetrically arranged on the scraper 501. A strip-shaped groove 5012 is opened inside the connecting seat 5011. The strip-shaped groove 5012 is vertical. A positioning protrusion 5021 is slidably arranged inside the strip-shaped groove 5012. An L-shaped bracket 502 is fixedly arranged on the side wall of the positioning protrusion 5021. The end of the L-shaped bracket 502 is welded to the side wall of the drive shaft 301. A reinforcing rib 5022 is installed at the corner of the L-shaped bracket 502. During the rotation of the drive shaft 301, the L-shaped bracket 502 on the side wall pushes the scraper 501 at the end to rotate along the guide rail 5013, thereby cleaning the baffle 303 and reducing the occurrence of blockage. In addition, as the baffle 303 moves up and down, the scraper 501 moves up and down synchronously, ensuring that the scraper 501 can move along the baffle 303, reducing the occurrence of blockage by large particles of raw materials.

[0053] Example 3:

[0054] The difference between the above embodiments and this embodiment is that:

[0055] like Figures 1 to 11 As shown, the drive shaft 301 has a wavy groove 305 on its side wall. The grooves 305 are symmetrically distributed and symmetrically arranged. Two guide rods 3051 are symmetrically slidably arranged inside the grooves 305. The guide rods 3051 are slidably arranged inside the connecting seats mounted on the baffle 303. During the rotation of the drive shaft 301, the position of the grooves 305 on the drive shaft 301 changes. The guide rods 3051 are slidably arranged on the grooves 305 and contact the baffle 303. The baffle 303 is limited by the insert rod 304 and can only move up and down. Therefore, as the position of the grooves 305 changes, the baffle 303 moves up and down, accelerating the downward movement of the mixed raw materials.

[0056] like Figures 1 to 11 As shown, in a specific embodiment, an arcuate groove 4011 is formed inside the annulus 401. A driven bevel gear 4012 is meshed with the side wall of the arcuate groove, and a driving bevel gear 3014 is meshed with the side wall of the driven bevel gear 4012. The driving bevel gear 3014 is fitted inside the arcuate groove 4011. The central shaft of the driving bevel gear 3014 is fixedly connected to the bottom of the transmission shaft 301, and the transmission shaft 301 passes through the baffle 303. The driving bevel gear 3014 is installed at the bottom of the transmission shaft 301 and rotates continuously. The driven bevel gear 4012 is meshed with the side wall of the driving bevel gear 3014, and the driven bevel gear 4012 begins to rotate.

[0057] like Figures 1 to 11 As shown, furthermore, a bearing seat 404 is screwed onto the side wall of the mixing shell 101. The bearing seat 404 has an internal mounting groove 4041, and a bearing 4042 is fitted into the inner wall of the mounting groove 4041. A connecting shaft 4022 is fitted into the inner wall of the bearing 4042. Several arc-shaped supports 402 are fixedly mounted on the connecting shaft 4022, and the connecting shaft 4022 is hollow. A positioning shaft 403 is fixedly mounted inside the mounting groove 4041, and the positioning shaft 403 movably passes through the hollow portion of the connecting shaft 4022. When the driven bevel gear 4012 rotates, it drives the arc-shaped supports 402 and the mixing rod 4021 on the side wall to rotate. After the mixing rod 4021 rotates, the side wall of the positioning rod 4031 intersects with the mixing rod 4021, thereby fully mixing the raw materials discharged from the preliminary mixing unit 300 and improving the mixing effect.

[0058] The implementation principle of a three-way catalyst raw material processing device in this embodiment is as follows:

[0059] First, the operator needs to open the sealing cover 103, pour a certain amount of three-way catalyst raw material into the stirring shell 101, and reseal the stirring shell 101 through the sealing cover 103. During the sealing process, the rectangular shaft 2011 at the bottom of the sealing cover 103 needs to be inserted into the rectangular inner cavity 2021.

[0060] Next, the user starts the drive motor 201, which drives the rectangular shaft 2011 to rotate. The rectangular shaft 2011 is inserted into the collar 202. At this time, the collar 202 and the drive shaft 301 begin to rotate. The first bracket 3011 and the second bracket 3012 are installed on the side wall of the drive shaft 301, and the first bracket 3011 and the second bracket 3012 begin to move around a circumference, thereby mixing and stirring the internal raw materials. During the continuous rotation of the first bracket 3011 and the second bracket 3012, the drive gear 302 at the end of the first bracket 3011 and the second bracket 3012... 2. Intermittent contact with the guide rack 3023, through the limiting of the guide rack 3023, eventually drives the drive gear 3022 to start rotating. After the drive gear 3022 rotates, it will drive the bottom gear shaft 302 to start rotating. The guide plate 3021 on which the gear shaft 302 is installed will start to rotate synchronously. Since the guide plate 3021 is installed on the side wall, when the guide plate 3021 rotates, it can drive the raw material in the center and the raw material on the side wall to mix, thereby improving the mixing effect and completing the initial mixing purpose. During the stirring process, a part of the raw material falls down from the sieve hole 3031 of the baffle 303.

[0061] During the rotation of the drive shaft 301, the position of the irregular groove 305 on the drive shaft 301 changes. A guide rod 3051 is slidably arranged on the irregular groove 305, and the guide rod 3051 contacts the baffle 303. The baffle 303 is limited by the insert rod 304 and can only move up and down. Therefore, as the position of the irregular groove 305 changes, it drives the baffle 303 to move up and down, accelerating the downward movement of the mixed raw materials.

[0062] During the rotation of the drive shaft 301, the L-shaped bracket 502 on the side wall pushes the scraper 501 at the end to rotate along the guide rail 5013, thereby cleaning the baffle 303 and reducing the occurrence of blockage. Furthermore, as the baffle 303 moves up and down, the scraper 501 moves up and down synchronously, ensuring that the scraper 501 can move along the baffle 303 and reducing the occurrence of blockage by large particles of raw materials.

[0063] The drive shaft 301 has a drive bevel gear 3014 installed at its bottom. The drive bevel gear 3014 rotates continuously. A driven bevel gear 4012 is meshed with the side wall of the drive bevel gear 3014. The driven bevel gear 4012 starts to rotate. When the driven bevel gear 4012 rotates, it drives the arc-shaped support 402 and the mixing rod 4021 on the side wall to rotate. After the mixing rod 4021 rotates, the side wall of the positioning rod 4031 intersects with the mixing rod 4021, thereby fully mixing the raw materials discharged by the preliminary mixing unit 300 and improving the mixing effect.

A limiting plate (3041) is installed at the end of the insert rod (304), and the limiting plate (3041) overlaps the bottom of the baffle (303). The drive shaft inside the initial mixing unit is driven by the drive unit. The rotation of the drive shaft drives the first and second supports to rotate synchronously, while the central stirring rod mixes with the raw materials. During the mixing process, the guide plate is rotated by the cooperation of the drive gear and the guide rack, thereby conveying the raw materials on the side wall to the center, which facilitates the mixing. During the mixing process, the raw materials that have reached a certain size enter the mixing unit through the screen holes of the baffle. During the rotation of the drive shaft, the drive bevel gear at the bottom starts to rotate, and the driven bevel gear meshes with the side wall of the drive bevel gear, which in turn drives the connected ring and arc-shaped bracket to rotate synchronously. The rotation of the arc-shaped bracket drives the connecting shaft and the positioning rod to rotate alternately, thereby stirring the raw materials passing through the preliminary stirring unit.
