AI Technical Summary
In the existing technology, when raw materials are fed into the eugenol reaction through the feeding pipe, external air can easily seep into the reaction chamber, especially when the feeding time is long. This results in a large amount of air being mixed into the reaction chamber, affecting product quality and increasing production costs.
A dual-exhaust eugenol reaction device was designed, including an exhaust feed pipe, a lifting device, a squeeze piston plate, an exhaust pipe, an intake pipe, a bottom sealing cover, a start/stop motor, and a nitrogen purging assembly. Air is discharged by squeezing the piston plate, and secondary exhaust is achieved using the nitrogen assembly. Combined with nitrogen concentration detection, it is ensured that all air is completely discharged.
This system enables dual air venting during raw material feeding, ensuring sufficient nitrogen inside the reaction chamber, preventing air infiltration, improving product quality stability, and reducing production costs.

Abstract
Description
Technical Field
[0001] This invention belongs to the field of eugenol reaction technology, and particularly relates to a dual-exhaust eugenol reaction device and its reaction process. Background Technology
[0002] Eugenol is mainly used for antibacterial and blood pressure-lowering purposes. It can also be used in perfume and fragrance formulations, as well as in various cosmetic and soap fragrance formulations. It can also be used in the blending of food flavorings. Eugenol is chemically unstable; it turns black and sticky when exposed to air and has a pungent odor. Therefore, if air is mixed in during processing, it will affect the quality of the finished product, leading to product spoilage and increased production costs. Current methods generally require purging the reaction chamber to fill it with nitrogen before feeding the raw materials. However, when feeding the raw materials through a feeding pipe, airflow often occurs between the outside air and the inside of the reaction chamber, especially during long feeding times, resulting in a large amount of air mixing into the reaction chamber. Therefore, the existing feeding structure needs to be upgraded to prevent air infiltration during feeding. Summary of the Invention
[0003] To address the shortcomings of the prior art, the present invention provides a dual-venting eugenol reaction apparatus and its reaction process that can prevent air infiltration during feeding.
[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: A dual-exhaust eugenol reaction apparatus includes a reaction chamber, an exhaust feed pipe, a lifting device, a compression piston plate, an exhaust pipe, an intake pipe, a bottom sealing cover, a start / stop motor, and a nitrogen purging assembly. An exhaust feed pipe is installed at the upper center of the reaction chamber. The lower end of the exhaust feed pipe is open and extends into the reaction chamber. A bottom sealing cover is installed at the lower end of the exhaust feed pipe. Start / stop motors are installed on both sides of the reaction chamber, controlling the vertical movement of the bottom sealing cover. A lifting device is installed on the upper exterior of the exhaust feed pipe, and a compression piston plate is installed inside the upper interior of the exhaust feed pipe. The lifting device drives the compression piston plate to move up and down. An exhaust pipe and an intake pipe are installed on the lower sides of the exhaust feed pipe, respectively. A nitrogen purging assembly is installed on the exhaust feed pipe, supplying nitrogen to the area below the compression piston plate.
[0005] Furthermore, the nitrogen purging assembly includes a nitrogen purging pipe, a folded conduit, an external air inlet pipe, a suction pump, and a nitrogen concentration detection device; an external air inlet pipe is installed on each of the two sides of the upper end of the exhaust-type feed pipe, and a suction pump is installed on the outer end of each external air inlet pipe; the lower end of each external air inlet pipe extends into the interior of the exhaust-type feed pipe and connects to the folded conduit; nitrogen purging pipes are connected to both sides of the extrusion piston plate; the upper side of each nitrogen purging pipe is connected to the lower end of the folded conduit; a nitrogen concentration detection device is installed on the exterior of one side of the reaction chamber, and the outer end of the exhaust pipe is connected to the nitrogen concentration detection device.
[0006] Furthermore, the lower end of the nitrogen flushing pipe is connected to the extrusion piston plate via a solenoid valve.
[0007] Furthermore, movable slide rails are respectively provided on both sides of the reaction chamber; lifting blocks are respectively connected to both sides of the bottom sealing cover by connecting rods; the lifting blocks are slidably installed on the movable slide rails; a rotating screw is connected to the lower side of the start / stop motor through a drive shaft; the rotating screw rotates through the movable slide rail and is threadedly connected to the lifting block.
[0008] Furthermore, the exhaust pipe is equipped with an exhaust check valve and a first on / off valve; the intake pipe is equipped with an intake check valve and a second on / off valve; and the inner ends of the exhaust pipe and the intake pipe are both equipped with dense baffles at the connection points with the exhaust-type feed pipe.
[0009] Furthermore, the upper surface of the bottom sealing cover has an upwardly convex arc structure.
[0010] Furthermore, the lifting device is a telescopic cylinder, and the lower end of the telescopic cylinder is connected to the upper middle of the extrusion piston plate via a telescopic shaft.
[0011] Furthermore, a feed inlet is provided on one side of the reaction chamber; a screw-on opening and closing connector is provided at the feed inlet.
[0012] A reaction process for a dual-venting eugenol reactor includes the following steps: Raw materials are fed into the venting feed pipe, the venting pipe is opened, and the intake pipe is closed. Then, a lifting device controls the extrusion piston plate to move downwards within the venting feed pipe, compressing the air inside the venting feed pipe and causing it to exit through the venting pipe. This continues until the extrusion piston plate exerts downward pressure on the raw materials, thus removing most of the air at once. The lifting device is then stopped, and the solenoid valve at the lower end of the nitrogen purging pipe is opened. Nitrogen gas is then drawn in by a suction pump, allowing the nitrogen gas to flow sequentially from the external intake pipe... The folded conduit and nitrogen flushing pipe enter below the extrusion piston plate, allowing nitrogen to enter the gaps between the raw materials. The compression of the nitrogen causes the air in the gaps between the raw materials to be expelled, achieving secondary air discharge. The airflow is discharged from the exhaust pipe and detected by the nitrogen concentration detection device. When the nitrogen concentration reaches the threshold, the suction pump stops pumping nitrogen and the solenoid valve at the lower end of the nitrogen flushing pipe is closed. Finally, the bottom sealing cover is moved downward by the opening and closing motor, which opens the lower end of the exhaust feed pipe, allowing the raw materials inside the exhaust feed pipe to be discharged into the reaction chamber. This achieves a dual air discharge operation mode.
[0013] The beneficial effects of this invention are as follows: 1. In this invention, the raw materials are not directly fed into the reaction chamber. Instead, the raw materials are first placed into the exhaust feed pipe. The air inside the exhaust feed pipe is then compressed by the squeeze piston plate, causing the air to be discharged from the exhaust pipe. This continues until the squeeze piston plate presses down on the raw materials, thus removing most of the air at once. Then, the solenoid valve at the lower end of the nitrogen purging pipe is opened, and nitrogen is drawn in by the suction pump. The nitrogen enters the space between the squeeze piston plate through the external air inlet pipe, the folded conduit, and the nitrogen purging pipe. The nitrogen then enters the gaps between the raw materials, and the compression of the nitrogen causes the air between the raw materials to be discharged, achieving a second air discharge. This dual air discharge operation mode is achieved, and the nitrogen concentration is detected by a nitrogen concentration detection device to ensure the effectiveness of air discharge.
[0014] 2. To achieve convenient and stable nitrogen input, this invention designs a nitrogen purging assembly, which includes a nitrogen purging pipe, a folded conduit, an external air inlet pipe, a suction pump, and a nitrogen concentration detection device. The nitrogen purging pipe and the external air inlet pipe are connected by a folded conduit for telescopic extension. In this way, when the nitrogen purging pipe moves downward with the extrusion piston plate to different material heights, it can always maintain continuity with the external air inlet pipe, facilitating nitrogen input. Thus, nitrogen can be conveniently input according to different material heights, and the structure is flexible in use. Attached Figure Description

An exhaust feed pipe 2 is installed in the middle of the upper end of the reaction chamber 1. The lower end of the exhaust feed pipe 2 is open and extends into the interior of the reaction chamber 1. A bottom sealing cover 7 is installed at the lower end of the exhaust feed pipe 2.

A nitrogen purging assembly 9 is installed on the exhaust feed pipe 2, supplying nitrogen to the area below the compression piston plate 4.
[0023] like Figures 1 to 6As shown, to facilitate stable nitrogen input following the movement of the extrusion piston plate 4, the nitrogen purging assembly 9 further includes a nitrogen purging pipe 91, a folded conduit 92, an external air inlet pipe 93, a suction pump 94, and a nitrogen concentration detection device 95. An external air inlet pipe 93 is installed on each side of the upper end of the exhaust-type feed pipe 2, and a suction pump 94 is installed at the outer end of each external air inlet pipe 93. The lower end of the external air inlet pipe 93 extends into the exhaust-type feed pipe 2 and connects to the folded conduit 92. Nitrogen purging pipes 91 are connected to both sides of the extrusion piston plate 4. The upper side of the nitrogen purging pipe 91 is connected to the lower end of the folded conduit 92. A nitrogen concentration detection device 95 is installed on the outside of one side of the reaction chamber 1, and the outer end of the exhaust pipe 5 is connected to the nitrogen concentration detection device 95. Furthermore, the lower end of the nitrogen purging pipe 91 is connected to the extrusion piston plate 4 via a solenoid valve 911.
[0024] like Figures 1 to 6 As shown, in order to facilitate stable up-and-down movement control of the bottom sealing cover 7, further, movable slide rails 11 are respectively opened on both sides of the reaction chamber 1; lifting blocks 72 are respectively connected to both sides of the bottom sealing cover 7 via connecting rods 71; the lifting blocks 72 are slidably installed on the movable slide rails 11; the lower side of the start / stop motor 8 is connected to a rotating screw 82 via a drive shaft 81; the rotating screw 82 is rotatably inserted into the movable slide rails 11 and threadedly connected to the lifting blocks 72.
[0025] like Figures 1 to 6 As shown, furthermore, in order to facilitate the discharge of compressed air, the exhaust pipe 5 is provided with an exhaust one-way valve 51 and a first on-off valve 52; in order to facilitate the upward repositioning of the extrusion piston plate 4 to draw in external airflow, the suction pipe 6 is provided with a suction one-way valve 61 and a second on-off valve 62; the inner ends of the exhaust pipe 5 and the suction pipe 6 are both provided with a dense baffle mesh at the connection with the exhaust-type feed pipe 2, so that the raw material overflow can be blocked by the dense baffle mesh.
[0026] like Figures 1 to 6 As shown, to facilitate material discharge, the upper surface of the bottom sealing cover 7 has an upwardly convex arc structure. To facilitate the up-and-down driving of the extrusion piston plate 4, the lifting device 3 is a telescopic cylinder, with the lower end of the telescopic cylinder connected to the upper middle of the extrusion piston plate 4 via a telescopic shaft 31. To facilitate the addition of raw materials, a feed inlet is provided on one side of the reaction chamber 1; a screw-on opening and closing connector 12 is provided at the feed inlet.
[0027] like Figures 1 to 6As shown, the reaction process of a dual-venting eugenol reactor includes the following steps: The raw material is fed into the venting feed pipe 2, the venting pipe 5 is opened, and the suction pipe 6 is closed. Then, the lifting device 3 controls the extrusion piston plate 4 to move downwards within the venting feed pipe 2, compressing the air inside the venting feed pipe 2 and causing it to be discharged from the venting pipe 5 until the extrusion piston plate 4 presses down against the raw material, thus achieving the discharge of most of the air at once. The lifting device 3 is stopped, and the solenoid valve at the lower end of the nitrogen purging pipe 91 is opened. Nitrogen gas is then drawn in by the suction pump 94, allowing the nitrogen gas to flow sequentially from the external inlet pipe 93. The folded conduit 92 and the nitrogen flushing pipe 91 enter below the extrusion piston plate 4, allowing nitrogen to enter the gap between the raw materials. The compression of the nitrogen causes the air in the gap between the raw materials to be discharged, achieving secondary air discharge. The airflow is discharged from the exhaust pipe 5 and detected by the nitrogen concentration detection device 95. When the nitrogen concentration reaches the threshold, the suction pump 94 stops pumping nitrogen and closes the solenoid valve at the lower end of the nitrogen flushing pipe 91. Finally, the bottom sealing cover 7 is moved downward by the start / stop motor 8, which opens the lower end of the exhaust feed pipe 2, allowing the raw materials inside the exhaust feed pipe 2 to be discharged into the reaction chamber 1. This achieves a dual air discharge operation mode.
[0028] In this invention, the raw materials are not directly fed into the reaction chamber 1. Instead, the raw materials are first placed into the exhaust feed pipe 2. The air inside the exhaust feed pipe 2 is compressed by the squeeze piston plate 4, causing the air to be discharged from the exhaust pipe 5. This continues until the squeeze piston plate 4 presses down on the raw materials, thus achieving the primary discharge of most of the air. Then, the solenoid valve at the lower end of the nitrogen purging pipe 91 is opened, and nitrogen is drawn in by the suction pump 94. The nitrogen enters the area below the squeeze piston plate 4 sequentially through the external air inlet pipe 93, the folded conduit 92, and the nitrogen purging pipe 91. The nitrogen then enters the gaps between the raw materials, and the compression of the nitrogen causes the air in the gaps to be discharged, achieving a secondary air discharge. This achieves a dual air discharge operation mode, and the nitrogen concentration is detected by the nitrogen concentration detection device 95 to ensure the effectiveness of the air discharge.
[0029] To achieve convenient and stable nitrogen input, this invention designs a nitrogen purging assembly 9, which includes a nitrogen purging pipe 91, a folded conduit 92, an external air inlet pipe 93, a suction pump 94, and a nitrogen concentration detection device 95. The nitrogen purging pipe 91 and the external air inlet pipe 93 are telescopically connected by the folded conduit 92. In this way, when the nitrogen purging pipe 91 moves downward with the extrusion piston plate 4 to different material heights, it can always maintain communication with the external air inlet pipe 93, facilitating nitrogen input. Thus, nitrogen can be conveniently input according to different material heights, and the structure is flexible in use.
