Description

Technical Field

[0001] The present invention relates to the technical field of reactor equipment, in particular to a reactor for producing a photovoltaic-grade EVA film crosslinking agent TAEC. Background Art

[0002] As a versatile piece of equipment, reactors play a vital role in industries such as chemical, pharmaceutical, food, and scientific research, primarily responsible for processes such as mixing substances, chemical reactions, and temperature control. Designed to withstand high temperatures and high pressures, these devices typically consist of a reactor, a stirring mechanism, a temperature control system, and an operating system.

[0003] As reactors are used continuously over a period of time, dirt and residue accumulate on their inner walls, necessitating regular cleaning to maintain proper operation. The importance of reactor cleaning cannot be underestimated; it is crucial for ensuring product quality, improving reaction efficiency, extending equipment life, ensuring operational safety, facilitating maintenance and inspection, and ensuring compliance with industry hygiene and regulations.

[0004] Currently, reactor cleaning methods can be broadly categorized as mechanical and chemical. Mechanical cleaning typically requires personnel to manually remove hard, sticky materials from the reactor, or to open the head and use specialized equipment to perform high-pressure water jet cleaning to remove hard and thick scale. Chemical cleaning, on the other hand, utilizes the circulation of specialized cleaning agents to remove soft and thin scale.

[0005] All of the above methods have limitations. Mechanical cleaning requires workers to ventilate the reactor to ensure safety and wear protective gear, which is time-consuming and inefficient. Furthermore, high-pressure water cleaning requires opening the head, making the operation relatively complex. While chemical cleaning can remove soft scale, long-term use may cause corrosion to the reactor material.

[0006] However, these current cleaning methods require the use of external forces or equipment and cannot achieve self-cleaning through the structure of the reactor itself. Summary of the Invention

[0007] The present invention discloses a reactor for producing photovoltaic-grade EVA film crosslinking agent TAEC, which aims to solve the problem that the existing reactors need to rely on external forces or equipment to clean the inside of the reactor, and cannot achieve the purpose of self-cleaning through the structure of the reactor itself.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] A reactor for producing TAEC, a crosslinking agent for photovoltaic-grade EVA film, comprising a reactor body, a multi-directional spray assembly rotatably disposed within the reactor body for cleaning the inner wall of the reactor, a drive assembly mounted on the head of the reactor body, and an adjustment assembly disposed above the drive assembly;

[0010] Specifically, the spray assembly includes an outer rotating drum rotatably connected to the reactor body cover at the upper portion, an inner rotating drum rotatably arranged inside the outer rotating drum, a row of water spray holes is provided on the side wall of the inner rotating drum located inside the reactor body, a through groove corresponding to the position of the water spray holes is provided on the side wall of the outer rotating drum, the bottom end of the outer rotating drum is connected to a blocking shell, a bottom nozzle is rotatably connected to the inside of the blocking shell, the upper end of the bottom nozzle is fixedly connected to the lower end of the inner rotating drum, a row of spray holes is provided on the bottom wall of the bottom nozzle, and a strip-shaped through groove adapted to the spray holes is provided at the bottom end of the blocking shell;

[0011] Specifically, the drive assembly includes a bevel gear sleeved on the upper end of the outer rotating drum, one side of the bevel gear is engaged with a drive gear, the drive gear is connected to the output shaft of the drive motor, and the drive motor is installed on a support frame arranged on the head of the reactor body.

[0012] Specifically, the adjustment assembly includes a friction plate fixedly mounted on the outer wall of the upper end of the outer rotating cylinder, an upper friction plate located above the lower friction plate and slidingly mounted on the outer wall of the inner rotating cylinder, the upper surface of the upper friction plate is connected to the telescopic ends of two symmetrically arranged electric cylinders, the electric cylinder is fixedly connected to the outer wall of the inner rotating cylinder through a connecting plate, and a fixed friction plate is arranged between the upper friction plate and the lower friction plate.

[0013] Furthermore, a conductive slip ring is installed above the adjustment component and on the outer wall surface of the inner drum.

[0014] Furthermore, a limiting ring is fixedly provided on the outer wall of the upper end of the inner rotating drum, and the limiting ring is rotatably provided in the sliding joint. A water receiving pipe is provided at the upper end of the sliding joint, and a sliding groove adapted to the limiting ring is provided in the sliding joint.

[0015] Furthermore, one side surface of the through groove and the strip-shaped through groove are both inclined surfaces.

[0016] Furthermore, two limiting grooves are provided on the inner ring edge of the upper friction disc, and the limiting grooves are slidably connected to limiting blocks fixedly provided on the outer wall of the outer rotating cylinder.

[0017] Furthermore, the upper and lower surfaces of the lower friction plate are both rough surfaces, and the lower surface of the upper friction plate and the upper surface of the fixed friction plate are both rough surfaces.

[0018] Furthermore, the sliding joint is fixedly connected to the end of the support frame through a U-shaped frame, and the shell of the conductive slip ring is fixedly connected to the U-shaped frame through a connecting plate.

[0019] Furthermore, a water channel is provided inside the inner drum.

[0020] Furthermore, the interior of the bottom nozzle is connected to the water flow channel of the inner drum. As can be seen from the above, the photovoltaic-grade EVA film crosslinking agent TAEC production reactor provided by the present invention has the following improvements and advantages compared with the existing technology:

[0021] 1. The present invention comprises a multi-directional spray assembly, a drive assembly, and an adjustment assembly. When the side walls and bottom wall of the reactor body need to be cleaned, the adjustment assembly controls the through slots and strip slots on the outer drum of the multi-directional spray assembly to rotate until the water spray holes and nozzles are fully exposed. The adjustment assembly then drives the inner and outer drums to rotate synchronously at a low speed under the drive motor. Simultaneously, a high-pressure water pipe is connected via a water connection pipe. High-pressure water flows through the water flow channel of the inner drum and is sprayed from the water spray holes and nozzles to wash away sticky matter on the side walls and bottom wall of the reactor body with high-pressure spray.

[0022] 2. When the material is normally stirred in the production reactor of the TAEC cross-linking agent for photovoltaic-grade EVA film provided by the present invention, the water spray holes on the inner drum and the spray holes on the bottom nozzle are staggered with the through grooves and the strip grooves, and at this time the electric cylinder will drive the upper friction plate to move downward and frictionally fit with the lower friction plate, and then drive the motor to drive the driving gear to rotate, thereby driving the bevel gear to drive the outer drum and the inner drum to rotate synchronously, and the material inside the reactor is stirred by the stirring paddle on the outer drum.

[0023] 3. With the cooperation of the multi-directional spray assembly, the driving assembly and the regulating assembly, the multi-directional spray assembly can not only realize the normal stirring of the materials in the reactor, but also perform high-pressure water jet cleaning on the inner side wall and bottom wall of the reactor, thus overcoming the shortcomings of the existing technology.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] refer to Figures 1 to 12 A reactor for producing photovoltaic-grade EVA film crosslinking agent TAEC includes a reactor body 1, a multi-directional spray assembly 2 for cleaning the inner wall of the reactor body 1, a drive assembly 3 mounted on the head of the reactor body 1, and an adjustment assembly 4 disposed above the drive assembly 3;

[0039] The spray assembly 2 includes an outer drum 201 rotatably connected to the head of the reactor body 1 at its upper portion, an inner drum 202 rotatably provided inside the outer drum 201, a row of water spray holes 203 being provided on the side wall of the inner drum 202 located inside the reactor body 1, a through slot 204 corresponding to the position of the water spray holes 203 being provided on the side wall of the outer drum 201, a blocking shell 205 being connected to the bottom end of the blocking shell 205, a bottom nozzle 206 being rotatably connected inside the blocking shell 205, the upper end of the bottom nozzle 206 being fixedly connected to the lower end of the inner drum 202, a row of spray holes 207 being provided on the bottom wall of the bottom nozzle 206, and a strip-shaped through slot 208 being provided at the bottom end of the blocking shell 205 to match the spray holes 207;

[0040] The driving assembly 3 includes a bevel gear 301 sleeved on the upper end of the outer rotating drum 201, and a driving gear 302 is engaged on one side of the bevel gear 301. The driving gear 302 is connected to the output shaft of the driving motor 303, and the driving motor 303 is installed on a support frame 304 set on the head of the reactor body 1.

[0041] In this embodiment, when the side walls and bottom walls of the reactor body 1 need to be cleaned, the inner drum 202 is fixed and does not rotate by controlling the adjusting component 4, so that the output shaft of the driving motor 303 drives the driving gear 302 to rotate, and the rotating driving gear 302 drives the bevel gear 301 fixedly sleeved on the outer drum 201 to rotate, thereby causing the outer drum 201 to rotate on the inner drum 202. When the through slots 204 and the strip through slots 208 on the outer drum 201 rotate, When the water spray holes 203 and the spray holes 207 are fully exposed, the drive motor 303 stops rotating. At this time, the inner drum 202 and the outer drum 201 are driven by the drive motor 302 by the adjustment component 4 to rotate synchronously at a low speed. Then, the high-pressure water pipe is connected through the water connecting pipe 601. The high-pressure water flows through the water flow channel 2023 of the inner drum 202 and is sprayed out from the water spray holes 203 and the spray holes 207, and the sticky matter is washed away by the high-pressure spray on the side walls and bottom wall of the reactor body 1.

[0042] When the reactor is stirring the materials normally, the water spray holes 203 on the inner drum 202 and the spray holes 207 on the bottom nozzle 206 are staggered with the through grooves 204 and the strip through grooves 208, and the electric cylinder 403 will drive the upper friction plate 402 to move downward and frictionally fit with the lower friction plate 401, thereby driving the motor 303 to drive the driving gear 302 to rotate, and then drive the bevel gear 301 to drive the outer drum 201 and the inner drum 202 to rotate synchronously, and stir the materials inside the reactor through the stirring paddle on the outer drum 201.

[0043] It should be noted that: the inner drum 202 is located on the side wall of the reactor body 1, and the high-speed, high-pressure water flow ejected from the water spray holes 203 can rinse the sticky materials on the side wall of the reactor body 1; secondly, each hole in the row of spray holes 207 opened on the bottom wall of the bottom nozzle 206 has a different angle with the horizontal plane, which can ensure that the high-pressure, high-speed water flow ejected from each hole can fully cover and rinse the entire bottom wall of the reactor, thereby ensuring the flushing effect; the row of water spray holes 203 and the row of spray holes 207 are located in the same vertical plane. When the through groove 204 on the outer drum 201 rotates until the spray holes 203 are fully exposed, the spray holes 207 are also completely located in the strip through groove 208 and are fully exposed.

[0044] Among them, the adjustment component 4 includes a friction disc 401 fixedly sleeved on the outer wall of the upper end of the outer rotating cylinder 201, an upper friction disc 402 is located above the lower friction disc 401 and slidably sleeved on the outer wall of the inner rotating cylinder 202, the upper surface of the upper friction disc 402 is connected to the telescopic ends of two symmetrically arranged electric cylinders 403, the electric cylinder 403 is fixedly connected to the outer wall surface of the inner rotating cylinder 202 through the connecting plate 404, and a fixed friction disc 405 is arranged between the upper friction disc 402 and the lower friction disc 401.

[0045] refer to Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 In this embodiment, when the reactor is working normally to stir the materials, the control electric cylinder 403 drives the upper friction plate 402 to move downward and rub against the lower friction plate 401. At this time, since the slider 2021 is clamped in the limiting groove 4021, the driving motor 303 drives the outer rotating drum 201 to rotate and can drive the inner rotating drum 202 to rotate synchronously at the same time. In this way, the outer rotating drum 201 and the inner rotating drum 202 will not rotate relative to each other, causing the spray hole 207 and the water spray hole 203 to rotate and be exposed at the strip groove 208 and the groove 204, thereby avoiding the material clogging the spray hole 207 and the water spray hole 203 during normal stirring.

[0046] When the material needs to be cleaned after stirring, the electric cylinder 403 is controlled to contract and drive the upper friction plate 402 to move upward, so that the upper surface of the upper friction plate 402 near the edge is frictionally fitted with the lower surface of the fixed friction plate 405, so that the inner drum 202 can be fixed and not rotated. At this time, the driving motor 303 is controlled to drive the driving gear 302 to rotate, and then the rotating driving gear 302 drives the outer drum 201 to rotate on the fixed inner drum 202 through the bevel gear 301 until the water spray hole 203 and the spray hole 207 on the bottom nozzle 206 are all exposed in the through groove 204 and the strip through groove 208, then the cleaning of the inner wall of the reactor body 1 can begin.

[0047] A conductive slip ring 5 is installed above the adjustment assembly 4 and on the outer wall of the inner drum 202 .

[0048] refer to Figure 5 、 Figure 7 By providing a conductive slip ring 5, the electric cylinder 403 can be powered when it rotates with the inner drum 202.

[0049] Among them, a limiting ring 2021 is fixedly set on the outer wall of the upper end of the inner rotating drum 202, and the limiting ring 2021 is rotatably set in the sliding joint 6. A water receiving pipe 601 is set at the upper end of the sliding joint 6, and a sliding groove 602 adapted to the limiting ring 2021 is set in the sliding joint 6.

[0050] refer to Figure 5 、 Figure 11 In this embodiment, by setting a sliding joint 6, when flushing the interior of the reactor body 1, the limiting ring 2021 fixedly set on the outer wall of the upper end of the inner drum 202 can rotate in the slide groove 602 of the sliding joint 6. At this time, the high-pressure water flow flowing in from the water pipe 601 can also flow smoothly into the water channel 2023 while the inner drum 202 rotates.

[0051] The through slot 204 and the strip-shaped through slot 208 both have a side surface that is an inclined surface.

[0052] It should be noted that one side surface of the through groove 204 and the strip through groove 208 are both inclined surfaces. This arrangement can ensure that when the outer drum 201 rotates on the inner drum 202, the materials previously stuck on the outer wall of the inner drum 202 and the outer wall of the bottom nozzle 206 corresponding to the through groove 204 and the strip through groove 208 can be scraped off, thereby ensuring the smooth rotation of the outer drum 201 on the inner drum 202.

[0053] The inner edge of the upper friction disc 402 is provided with two limiting grooves 4021 , and the limiting grooves 4021 are slidably connected to the limiting blocks 2022 fixedly provided on the outer wall of the outer rotating cylinder 202 .

[0054] By providing the limiting groove 4021 , it can be ensured that the upper friction disc 402 can move up and down along the limiting block 2022 driven by the electric cylinder 403 .

[0055] The upper and lower surfaces of the lower friction disc 401 are both rough surfaces, and the lower surface of the upper friction disc 402 and the upper surface of the fixed friction disc 405 are both rough surfaces.

[0056] The sliding joint 6 is fixedly connected to the end of the support frame 301 through the U-shaped frame 7 , and the shell of the conductive slip ring 5 is fixedly connected to the U-shaped frame through the connecting plate 8 .

[0057] A water passage 2023 is provided inside the inner drum 202 .

[0058] The interior of the bottom nozzle 206 is connected to the water flow channel 2023 of the inner drum 202 .

[0059] Working principle: When the side walls and bottom walls of the reactor body 1 need to be cleaned, the electric cylinder 403 is controlled to contract and drive the upper friction disk 402 to move upward, so that the upper surface of the upper friction disk 402 near the edge is frictionally fitted with the lower surface of the fixed friction disk 405, so that the inner drum 202 can be fixed and not rotated. At this time, the driving motor 303 is controlled to drive the driving gear 302 to rotate, and then the rotating driving gear 302 drives the outer drum 201 to rotate on the fixed inner drum 202 through the bevel gear 301 until the water spray holes 203 and the spray holes 207 are completely exposed in the through groove 204 and the strip through groove 208. The high-pressure water flowing in through the water receiving pipe 601 can flow through the water flow channel 2023 of the inner drum 202 and be sprayed out from the water spray holes 203 and the spray holes 207 to wash the side walls and bottom walls of the reactor.

[0060] When the reactor is working normally to stir the materials, the water spray holes 203 on the inner drum 202 and the spray holes 207 on the bottom nozzle 206 are staggered with the through groove 204 and the strip through groove 208. Then the electric cylinder 403 is controlled to drive the upper friction plate 402 to move downward and rub against the lower friction plate 401. At this time, since the slider 2021 is engaged in the limiting groove 4021, the driving motor 303 drives the driving gear 302 to rotate, and then drives the bevel gear 301 to drive the outer drum 201 and the inner drum 202 to rotate synchronously, so that the stirring paddle on the outer drum 201 can stir the materials inside the reactor.

[0061] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
