Description

Technical Field

[0001] This utility model relates to the field of workshop air purification technology, specifically to an automatic control system for the environment of a chemical fiber workshop. Background Technology

[0002] The chemical fiber workshop generates a large amount of high-temperature waste gas during the production process. This waste gas contains harmful gases such as small organic molecules, trace amounts of oil mist, and oligomer dust. Moreover, the workshop needs to be well-sealed, which means that a large amount of high-temperature waste gas cannot be effectively circulated and discharged, making the workshop stuffy and with poor air quality, which has a great impact on the working environment of employees and product quality.

[0003] Chinese Patent Publication No. CN217662130U discloses a device for recovering and reusing dusty waste gas in a cleanroom. The device includes a treatment box, a fan fixedly connected to the top of the box, an inlet pipe fixedly connected to the top of the fan, an outlet pipe fixedly connected to the bottom of the box, a first filter screen movably connected inside the box, a second filter screen movably connected inside the box, a housing fixedly connected to the left side of the box, and a transmission device fixedly connected inside the housing. The transmission device includes an electric push rod fixedly connected inside the housing. In use, the device opens the box door using a handle, activates the electric push rod, which moves a connecting plate and a connecting rod to the right. The moving connecting rod moves a push block, which in turn moves a transmission block up and down. The moving transmission block moves a sliding rod and a locking block, which in turn moves a locking rod out of its locking hole, allowing the first and second filter screens to be disassembled and replaced.

[0004] The device filters the workshop exhaust gas through a first filter and a second filter. However, the workshop exhaust gas has a certain temperature. The device only filters the exhaust gas before discharging it, but does not cool it down. This results in the discharged gas having a certain temperature, which affects the working environment of the workshop. Utility Model Content

[0005] To address the aforementioned issues, an automatic environmental control system for chemical fiber workshops is provided. This system uses a fan to draw waste gas into a conveying pipe, which then transports the waste gas to a purification chamber. The purification chamber utilizes filter plates and activated carbon filters to purify the waste gas. Finally, the purified air is discharged, achieving air circulation. As the waste gas flows, it is cooled by coolant inside a cooling cylinder, preventing the discharged air from carrying a certain temperature that could negatively impact the working environment within the workshop.

[0006] To address the problems of existing technologies, this utility model provides an automatic environmental control system for a chemical fiber workshop, including a treatment box. A waste gas detector for detecting waste gas is installed at the front end of the treatment box. A fan is installed inside the treatment box, and the input end of the fan is connected to an air intake hopper for adsorbing waste gas. The treatment box also contains a cooling cylinder for cooling the waste gas and a storage cylinder for storing coolant. An installation plate is also installed inside the treatment box, and a purification box is installed on top of the installation plate. The output end of the fan is connected to a conveying pipe for transporting waste gas. The conveying pipe is spirally wound around the outer wall of the cooling cylinder and communicates with the interior of the purification box.

[0007] Preferably, the processing tank is equipped with an infusion pump, the inlet of which is connected to the bottom outlet of the cooling cylinder via a pipe, the output of which is connected to the inside of the storage cylinder via a pipe, and the cooling cylinder and the storage cylinder are connected via a pipe.

[0008] Preferably, a dual-axis motor is provided at the top of the storage cylinder, the lower output shaft of the dual-axis motor is vertically connected to a stirring rod, the stirring rod extends into the coolant in the storage cylinder, and the upper output shaft of the dual-axis motor is connected to a rotating rod, one end of which extends into the interior of the purification chamber.

[0009] Preferably, the outer wall of the cooling cylinder is provided with heat dissipation fins for rapid heat dissipation of the coolant.

[0010] Preferably, symmetrical spring telescopic rods are provided on both sides of the inner wall of the purification box, and a filter plate for filtering impurities is provided at the telescopic end of the spring telescopic rod, and a plurality of abutment blocks for squeezing the filter plate are provided on the outer wall of the rotating rod.

[0011] Preferably, the interior of the purification box is also equipped with an activated carbon adsorption plate for purifying the waste gas.

[0012] The advantages of this utility model compared to the prior art are:

[0013] 1. The exhaust gas is drawn into the conveying pipe by the fan, and then transported to the purification chamber by the conveying pipe. The exhaust gas is purified by the filter plates and activated carbon filter plates inside the purification chamber. Finally, the purified air is discharged to achieve the purpose of air circulation. When the exhaust gas flows, the coolant inside the cooling cylinder can cool the exhaust gas to prevent the discharged air from having a certain temperature and affecting the working environment in the workshop.

[0014] 2. The coolant inside the storage tank can be transported to the cooling tank by the infusion pump, and then flow from the cooling tank to the storage tank, so that the coolant inside the cooling tank can circulate and prevent the coolant inside the cooling tank from getting too hot, which would prevent the exhaust gas from being effectively cooled.

[0015] 3. The lower output shaft of the dual-shaft motor drives the stirring rod to rotate, thereby stirring the coolant inside the storage tank and accelerating the heat dissipation of the coolant. At the same time, the heat dissipation fins can further dissipate heat from the coolant. The upper output of the dual-shaft motor drives the rotating rod to rotate, and the contact block on the outer wall of the rotating rod also rotates, thereby reciprocatingly squeezing the filter plate. Under the action of the spring telescopic rod, the filter plate moves back and forth to prevent impurities in the exhaust gas from clogging the filter holes and affecting the airflow.

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 6 As shown, this utility model provides:

[0025] The automatic environmental control system for the chemical fiber workshop includes a treatment box 1. A waste gas detector 2 for detecting waste gas is installed at the front end of the treatment box 1. A fan 4 is installed inside the treatment box 1. The input end of the fan 4 is connected to an air suction hopper 3 for adsorbing waste gas. The treatment box 1 also has a cooling cylinder 6 for cooling the waste gas and a storage cylinder 7 for storing coolant inside. The treatment box 1 also has an installation plate 9 inside. A purification box 10 is installed on the top of the installation plate 9. The output end of the fan 4 is connected to a conveying pipe 5 for transporting waste gas. The conveying pipe 5 is spirally wound around the outer wall of the cooling cylinder 6 and connected to the interior of the purification box 10.

[0026] The air quality in the workshop is detected by the exhaust gas detector 2. When the exhaust gas in the workshop meets the standards, the fan 4 is started to draw the exhaust gas into the inside of the conveying pipe 5. Then, the exhaust gas is transported to the inside of the purification box 10 by the conveying pipe 5. The purification box 10 can purify the exhaust gas. Afterward, the exhaust gas can be cooled by the coolant inside the cooling cylinder 6 to prevent the exhaust air from having a certain temperature and affecting the working environment in the workshop. In addition, a wind speed sensor for detecting wind speed and a temperature sensor for detecting temperature can be installed inside the treatment box 1. The exhaust gas detector 2 is model: HYPERSENSE1000, the wind speed sensor is model: Siemens QVM62.1, and the temperature sensor is model: THT-N263A DC12-24V4-20mA.

[0027] like Figure 4 As shown, the processing tank 1 is equipped with an infusion pump 13. The inlet of the infusion pump 13 is connected to the bottom outlet of the cooling cylinder 6 through a pipe. The output end of the infusion pump 13 is connected to the inside of the storage cylinder 7 through a pipe. The cooling cylinder 6 and the storage cylinder 7 are connected through a pipe.

[0028] The coolant inside the storage cylinder 7 can be transported to the cooling cylinder 6 by the infusion pump 13, and then flow from the cooling cylinder 6 to the storage cylinder 7, so that the coolant inside the cooling cylinder 6 can circulate and prevent the coolant inside the cooling cylinder 6 from being too hot and unable to effectively cool the exhaust gas.

[0029] like Figure 5 and Figure 6 As shown, a dual-axis motor 11 is installed at the top of the storage cylinder 7. The lower output shaft of the dual-axis motor 11 is vertically connected to the stirring rod 14, which extends into the coolant in the storage cylinder 7. The upper output shaft of the dual-axis motor 11 is connected to a rotating rod 12, one end of which extends into the interior of the purification box 10.

[0030] The lower output shaft of the dual-axis motor 11 drives the stirring rod 14 to rotate, thereby stirring the coolant inside the storage cylinder 7 and accelerating the heat dissipation of the coolant.

[0031] like Figure 4 As shown, the outer wall of the cooling cylinder 6 is provided with heat dissipation fins 8 for rapid heat dissipation of the coolant.

[0032] The heat dissipation fins 8 can be used to further dissipate heat from the coolant.

[0033] like Figure 6 As shown, symmetrical spring telescopic rods 17 are provided on both sides of the inner wall of the purification box 10. The telescopic ends of the spring telescopic rods 17 are provided with filter plates 16 for filtering impurities. The outer wall of the rotating rod 12 is provided with a plurality of abutment blocks 18 for squeezing the filter plates 16.

[0034] Impurities in the exhaust gas can be filtered by using the filter plate 16 inside the purification box 10. Then, the rotating rod 12 is driven by the dual-axis motor 11 to rotate. At the same time, the contact block 18 on the outer wall of the rotating rod 12 also rotates, thereby repeatedly squeezing the filter plate 16. Under the action of the spring telescopic rod 17, the filter plate 16 moves back and forth to prevent impurities in the exhaust gas from clogging the filter holes and affecting the airflow.

[0035] like Figure 6 As shown, the interior of the purification box 10 is also equipped with an activated carbon adsorption plate 15 for purifying the exhaust gas.

[0036] The activated carbon adsorption plate 15 can purify the exhaust gas, and finally the purified air is discharged to achieve the purpose of air circulation.

[0037] Working Principle: The device is moved to the workshop where air purification is needed. The exhaust gas detector 2 detects the air quality in the workshop. When exhaust gas is detected, the fan 4 is activated to draw the exhaust gas into the conveying pipe 5. The conveying pipe 5 then transports the exhaust gas to the purification chamber 10. The filter plates 16 and activated carbon filter plates 16 inside the purification chamber 10 purify the exhaust gas. Finally, the purified air is discharged, achieving air circulation. As the exhaust gas flows, the cooling liquid inside the cooling cylinder 6 cools it, preventing the discharged air from containing a certain temperature that could affect the working environment in the workshop. To ensure effective cooling of the exhaust gas, the infusion pump 13 and the dual-shaft motor 11 are activated. The infusion pump 13 cools the liquid inside the storage cylinder 7. The coolant is transported to the interior of the cooling cylinder 6, and then flows from the cooling cylinder 6 to the storage cylinder 7, allowing the coolant inside the cooling cylinder 6 to circulate. This prevents the coolant temperature inside the cooling cylinder 6 from becoming too high, which would prevent it from effectively cooling the exhaust gas. When the lower output shaft of the dual-axis motor 11 is working, it drives the stirring rod 14 to rotate, thereby stirring the coolant inside the storage cylinder 7 and accelerating the heat dissipation of the coolant. At the same time, the heat dissipation fins 8 can further dissipate heat from the coolant. When the upper output shaft of the dual-axis motor 11 is working, it drives the rotating rod 12 to rotate. At the same time, the contact block 18 on the outer wall of the rotating rod 12 also rotates, thereby reciprocatingly squeezing the filter plate 16. This causes the filter plate 16 to move back and forth under the action of the spring telescopic rod 17, preventing impurities in the exhaust gas from clogging the filter holes and affecting the airflow.
