DETAILED DESCRIPTION
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0020] See also Figures 1 to 11 The present invention is aimed at a vegetable processing production line, especially a vegetable production line in instant noodle vegetable seasoning packets, and designs a multi-stage high-efficiency purification circulation system including a purification box 1. The purification box 1 is divided into a dry purification chamber 11 and a wet purification chamber 12 and an air storage chamber 17 by a baffle 10. The dry purification chamber 11 is connected to a dust collection pipeline and a local dust collection hood on the production line. The air storage chamber 17 passes clean air into the vegetable air separation equipment for recycling. The layout of the purification box 1 can be diversified. The present invention only shows the internal structure and mechanical components. The actual internal structure can be arranged according to needs. Specifically, it includes the following embodiments: Example 1:
[0021] refer to Figures 1 to 4The purification box 1 and the baffle 10 are respectively provided with a first air inlet 21 and a second air inlet 22. A fan 14 is installed on the upper part of the baffle 10. The wet purification chamber 12 is provided with a cooling box 13 and a spray pipe 9. The cooling box 13 is located between the first air inlet 21 and the second air inlet 22. The gas that has passed the first dust removal in the dry purification chamber 11 is extracted by the fan 14 and enters the cooling box 13. Two groups of dust removal components 2 are arranged in the dry purification chamber 11. The dust removal component 2 includes a corrugated filter plate 25. The two ends of the corrugated filter plate 25 are respectively fixedly connected to the rubber sheet 27. The rubber sheet 27 is fixed with the block 28. The block 28 is clamped with the inner wall of the dry purification chamber 11. The dust removal component 2 is quickly disassembled and assembled with the chamber wall through the block 28, and maintenance is convenient. When the fan 14 inhales air, it drives the elastic rubber sheet 27 to stretch, and the corrugated filter plate 25 can be folded and retracted, which improves the filtration efficiency on the one hand and reduces the accumulation of dust on the other hand.
[0022] After the first dust removal, the air enters the cooling box 13, and is first sprayed by the nozzle on the spray pipe 9 to remove and absorb dust, achieving the second dust removal and cooling the air to a certain extent, because the temperature of the gas coming from the production line will be much higher than the room temperature.
[0023] In order to further reduce the gas temperature and use the heat of the gas to dry the outside air, so that the outside air can be used for the air separation equipment and realize recycling, specifically, three groups of heat exchange tubes 4 are set in the cooling box 13, one end of the heat exchange tube 4 is rotatably connected to the cooling box 13 and connected to the wet purification bin 12 through the air hole 41, the three groups of air holes 41 are opened on the top of the cooling box 13, and the other end of the heat exchange tube 4 is connected to the gas storage bin 17. The gas enters the three groups of heat exchange tubes 4 through the air hole 41, and multiple groups of fans are fixed on the outside of the heat exchange tube 4. Leaf 42, by setting an air suction fan in the air storage bin 17, the outside air will enter from the first air inlet 21, and the ventilation ports 43 are opened on both side walls of the cooling box 13. The outside air enters the cooling box 13 through the ventilation ports 43, and then enters the air storage bin 17. The outside air exchanges heat with the heat exchange tube 4 to reduce the gas temperature in the heat exchange tube 4, and the gas in the heat exchange tube 4 is discharged into the air storage bin 17 after two dust removals and two coolings as clean dry gas for air selection. Moreover, the outside air also enters the air storage bin 17 after heat exchange.
[0024] In addition, a drying component 5 is fixed on one side of the cooling box 13 close to the first air inlet 21, which is used to further remove moisture from the external air. Specifically, the drying component 5 includes a water-absorbing sponge 51 and a water filter clamp 52. The water-absorbing sponge 51 is fixed on the mounting frame 53, and the mounting frame 53 is fixed to the cooling box 13. The water-absorbing sponge 51 is mounted in the water filter clamp 52. The water-absorbing sponge 51 can absorb moisture from the external air. In order to maintain the water absorption of the water-absorbing sponge 51, the water filter clamp 52 can move up and down under the drive of the driving component 6 to squeeze out the moisture from the water-absorbing sponge 51. Specifically, the inner diameter of the water filter clamp 52 is smaller than the thickness of the water-absorbing sponge 51, so that the water-absorbing sponge 51 can be squeezed out of the water when moving, so as to maintain dryness and water absorption.
[0025] In order to control the circulation efficiency, when the gas in the dry purification chamber 11 is at a high temperature, the high-temperature gas discharge volume can be increased and the amount of external gas entering can be increased. The present invention adopts a method of controlling the air intake volume. Specifically, referring to Figure 1 and Figure 3 as well as Figure 6 The top of the wet purification chamber 12 is also provided with an air intake control assembly 3, which includes a guide plate 31 and a shutter 32. The guide plate 31 drives the shutter 32 to move up and down to control the air intake volume of the first air inlet 21. The ventilation port 43 near the first air inlet 21 includes three groups of strip-shaped air intake holes 201. Each group of strip-shaped air intake holes 201 is provided with a shutter 32. The shutter 32 can block the strip-shaped air intake holes 201. The multiple shutters 32 are fixed to each other by the connecting rod 35. The shutters 32 correspond to the strip-shaped air intake holes 201 one by one. The shutters 32 can block the strip-shaped air intake holes 201. As the shutters 32 move, the aperture of the strip-shaped air intake holes 201 becomes larger and larger, and the air intake volume increases. During operation, by increasing the power of the fan 14 and the suction force, the gas is accelerated to enter the wet purification chamber 12, and the gas will lift the guide plate 31.
[0026] In order to make the guide plate 31 control the movement of the baffle 32, specifically, the guide plate 31 is triangular, and a wave-shaped protrusion is provided on its surface to enhance the airflow guidance and reduce turbulence loss. One side of the guide plate 31 is fixed with two symmetrically arranged springs 33, and the springs 33 are fixed to the inner wall of the top of the wet purification chamber 12. The guide plate 31 moves along the guide groove 34, and the guide groove 34 is provided on the side wall of the wet purification chamber 12. The guide plate 31 is fixed to one end of the connecting rod 35, and the connecting rod 35 is fixed to the side wall of the wet purification chamber 12. The other end of 5 is fixed to the baffle 32, and two groups of guide grooves 34 and connecting rods 35 are symmetrically arranged, and the guide plate 31, the baffle 32, the guide groove 34 and the connecting rod 35 are of lightweight design, such as plastic material. When the gas accelerates into the wet purification chamber 12, the gas will cause the guide plate 31 to quickly lift up, driving the connecting rod 35 to rise, thereby causing the baffle 32 to rise, reducing the blocked area, making the leakage diameter of the strip air inlet 201 larger, and increasing the air intake of the outside air, thereby accelerating the heat exchange between the heat exchange tube 4 and the outside air.
[0027] It should be noted that, as a large amount of outside air enters the wet purification chamber 12, the heat exchange tube 4 needs to improve the heat exchange effect and the drying effect. Therefore, the present application enables the heat exchange tube 4 to rotate, increases the contact area, improves the heat exchange efficiency, and reduces the water vapor carried by the outside air. Specifically, refer to Figure 8 and Figure 9 A rotating assembly 7 is provided at the upper and lower ends of the heat exchange tube 4. The rotating assembly 7 includes a rotating disk 71 and an air cylinder 72. The heat exchange tube 4 is inserted into the circular hole opened in the rotating disk 71 and fixed. The heat exchange tube 4 adopts an integrated design, including multiple pipes, and a plurality of circular holes are also provided on the corresponding rotating disk 71. The rotating disk 71 is rotatably and sealedly connected to the air cylinder 72. The upper air cylinder 72 is communicated with the air hole 41, and the air cylinder 72 in the lower rotating assembly 7 is communicated with the outside through an exhaust pipe 73.
[0028] During operation, the entry of external air will blow the fan blades 42, causing the heat exchange tube 4 to rotate. The rotating disks 71 at both ends of the heat exchange tube 4 will rotate, and the rotating heat exchange tube 4 increases the contact area with the external air. Moreover, the fan blades 42 and the heat exchange tube 4 are both lightweight in design. In order to prevent the external air from blowing the fan blades 42 with little force, the present invention designs a circular air cylinder 72, on the surface of which a transmission device and a servo motor can be coaxially arranged to drive the heat exchange tube 4 to rotate. Of course, the air storage bin 17 is provided with an intake fan to increase the rotation speed of the fan blades 42.
[0029] Among them, reference Figure 6 The ventilation port 43 close to the second air inlet 22 includes four groups of rectangular air inlet holes 202.
[0030] The exhaust pipe 73 is a threaded pipe that can be twisted without hindering the swing of the heat exchange pipe 4 .
[0031] As a further explanation of this embodiment, the drive assembly 6 includes a drive source and a pressure plate 61. The drive source can be a servo motor. The drive source drives the pressure plate 61 to move up and down in the cooling box 13. The output end of the drive source is coaxially fixed with the first bevel gear 62, and the first bevel gear 62 is coaxially fixed with the first rotating shaft 90. The first rotating shaft 90 is connected to the cooling box 13 bearing. The first bevel gear 62 and the second bevel gear 63 are meshed and connected. The second bevel gear 63 is coaxially fixed with the lead screw 64. The lead screw 64 is connected to the cooling box 13 bearing. The lead screw 64 is threadedly connected to the guide sleeve 65. The guide sleeve 65 is fixedly connected to the pressure plate 61. The pressure plate 61 is fixed to the guide rod 66. The guide rod 66 moves along the guide hole 67. The guide hole 67 is opened on the inner wall of the cooling box 13.
[0032] During operation, the driving source rotates the lead screw 64, thereby moving the guide sleeve 65 downward and causing the pressing plate 61 to move downward. It should be noted that when the pressing plate 61 descends, the extrusion drying component 5 will be controlled in a linked manner. Specifically, refer to Figure 10-11 The guide rod 66 secures the first magnet 601, and the water filter clip 52 secures the second magnet 602. The first magnet 601 and the second magnet 602 are disposed on the partition 15 and attract each other. The partition 15 is disposed within the cooling box 13. When the guide rod 66 descends, it drives the first magnet 601 downward, causing the second magnet 602 attracted to it to drive the water filter clip 52 downward, squeezing out moisture from the absorbent sponge 51. This improves the dryness of the outside air after it enters through the first and second air inlets 21 and 22, further reducing the water vapor content.
