Description

Technical Field

[0001] The present invention relates to the field of waste gas treatment, and more specifically, to an environment-friendly waste gas treatment and recycling device for a drum-type tea fixation machine. Background Art

[0002] The drum-type tea fixation machine is one of the commonly used devices in the tea processing process. Its main function is to destroy the enzyme activity in fresh tea leaves through high temperature to prevent tea from oxidizing and deteriorating. At the same time, the water in the tea leaves evaporates to achieve the effects of withering and fixation. During the use of traditional drum-type tea fixation machines, a large amount of waste gas is generated. These waste gases contain the aroma components of tea, dust, and some harmful gases. If not treated and directly discharged, it will cause environmental pollution.

[0003] However, in some existing waste gas treatment devices for drum-type tea fixation machines, there are still many problems. On the one hand, the treatment efficiency of the waste gas treatment equipment is low. For some complex waste gas components, such as low-concentration volatile organic compounds and fine particles, it is difficult to achieve an ideal removal effect, resulting in non-compliant waste gas emissions and unable to meet the increasingly strict environmental protection requirements. On the other hand, many waste gas treatment devices have obvious deficiencies in recycling. They only simply treat the waste gas and then discharge it, without making full use of resources such as the heat energy in the waste gas, causing waste of energy and increasing the production cost of tea processing.

[0004] For the problems in the related art, no effective solution has been proposed yet. Summary of the Invention

[0026] Such as Figures 1 - 10As shown in the figure, the circulation component 5 includes an adjusting pipe 501, which is used to compress the output waste gas to ensure the output effect of the hot and cold ends of the vortex tube 502. The adjusting pipe 501 is connected to one end of the first output pipe 410 through a flange. One end of the adjusting pipe 501 is connected to a vortex tube 502. The vortex tube 502 is a conventional existing structure, so it will not be described in detail here. The two ends of the vortex tube 502 are connected to a second output pipe 503 and a third output pipe 504. A conveying pipe 505 is connected to the second output pipe 503 and the third output pipe 504. A second motor 506 is arranged on the conveying pipe 505 through a fixing frame. A driving gear 507 is arranged on the output shaft of the second motor 506. An adjusting cylinder 508 is arranged on the conveying pipe 505. The driving gear 507 extends into the interior of the adjusting cylinder 508 and is meshed with a driven gear 509. An adjusting disc 510 is arranged on the driven gear 509. A first adjusting groove 511 with a hexagonal structure and a second adjusting groove 512 with an elliptical structure are respectively formed on one side of the adjusting disc 510 and the inner wall of the adjusting cylinder 508.

Second control valves 8, third control valves 9, fourth control valves 10 and fifth control valves 11 are respectively arranged on the second output pipe 503, the third output pipe 504 and the conveying pipe 505, which are used to switch the effect, so as to realize the switching effect of hot and cold gases.

[0027] In summary, by means of the above technical solution of the present invention, during the process of the driving structure 2 driving the tea-killing cylinder 3 to kill the tea, waste gas containing components such as dust, tea hairs, and low-concentration volatile organic compounds is generated. When the tea-killing operation starts, the waste gas is inhaled into the interior of the filter cylinder 402 through the waste gas pipe 401. This process is realized by the first motor 413 driving the conveying blade 403 to rotate. The rotation of the conveying blade 403 generates negative pressure to ensure that the waste gas effectively enters the filter cylinder 402. After the waste gas enters the filter cylinder 402, it is filtered successively through a plurality of filter meshes 405. The filter meshes 405 are installed on the rotating rod 404, and the rotating rod 404 is driven to rotate by another output shaft of the first motor 413 through a coupling, thereby driving the rotating rod 404 to rotate. At the same time, a cleaning scraper 406 is installed on the rotating rod 404. The cleaning scraper 406 is in contact with the filter meshes 405 and the inner wall of the filter cylinder 402. During the process of the rotating rod 404 driving the filter meshes 405 to rotate, the cleaning scraper 406 cleans the filter meshes 405, scrapes off the filtered particulate matter and other impurities, prevents the filter meshes 405 from being blocked, ensures the filtering effect, and the scraped-off impurities are discharged through the sewage pipe 407; The filtered waste gas is sent into the gas detector 408 through the detection pipe 409 for detection. The gas detector 408 detects various indexes of the waste gas (such as particulate matter concentration, volatile organic compound concentration, etc.) to judge whether the waste gas meets the emission standard. If the detection result shows that the waste gas is unqualified, the first control valve 412 on the circulation treatment pipe 411 is opened, and the first control valve 412 on the first output pipe 410 is closed. The circulation treatment pipe 411 re-conveys the waste gas back into the interior of the filter cylinder 402 for re-filtering treatment. The waste gas undergoes the filtering process of multiple layers of filter meshes 405 again until the gas detector 408 detects that it is qualified and meets the emission standard; The filtered and qualified waste gas is output through the first output pipe 410 and enters the regulating pipe 501. The regulating pipe 501 compresses the waste gas, and then introduces the waste gas into the vortex tube 502. The vortex tube 502 separates the waste gas into two parts of hot and cold gases, which are respectively output through the second output pipe 503 and the third output pipe 504 and enter the inside of the conveying pipe 505 or are directly output through the second output pipe 503 and the third output pipe 504. A second motor 506 is installed on the conveying pipe 505. The output shaft of the second motor 506 drives the driving gear 507 to rotate. The driving gear 507 meshes with the driven gear 509 inside the regulating cylinder 508, thereby driving the regulating disc 510 to rotate. A regulating plate 515 is connected between the first regulating groove 511 on the regulating disc 510 and the second regulating groove 512 on the inner wall of the regulating cylinder 508. By changing the position of the regulating plate 515, the gas flow rate inside the conveying pipe 505 can be adjusted, and thus the amount of waste gas entering the green tea fixing cylinder 3 can be controlled. A plurality of auxiliary pipes 514 are also connected to the conveying pipe 505. An output hood 513 is installed at one end of the auxiliary pipe 514. The output hood 513 is arranged opposite to the green tea fixing cylinder 3. Through the auxiliary pipes 514 and the output hood 513, the treated waste gas is conveyed back to different positions of the green tea fixing cylinder 3, that is, to the outer wall and the inside of the green tea fixing cylinder 3. A plurality of temperature sensors 12 and humidity sensors 13 are embedded in the outer wall of the green tea fixing cylinder 3 for real-time monitoring of the temperature and humidity of the tea leaves during the green tea fixing process. The controller 14 controls the rotation speed of the second motor 506 according to the data transmitted by the temperature sensors 12 and the humidity sensors 13, thereby adjusting the rotation speed of the regulating disc 510 and the position of the regulating plate 515, and further controlling the amount of waste gas entering the green tea fixing cylinder 3; When the temperature of the tea leaves is relatively low during the green tea fixing process and more heat is needed, the controller 14 adjusts the waste gas delivery volume to allow more hot waste gas to enter the green tea fixing cylinder 3 to assist in fixing the tea leaves. When the temperature of the tea leaves is relatively high and cooling is required, the controller 14 adjusts the waste gas delivery volume to allow more cold waste gas to enter the green tea fixing cylinder 3 to cool the fixed tea leaves. Under the control of the controller 14, the waste gas delivery volume is accurately adjusted to realize the recycling of waste gas heat energy, assist in fixing and cooling the tea leaves, reduce energy consumption, and improve the environmental friendliness and economic benefits of tea processing.
