Description

Technical Field

[0001] This utility model relates to the technical field of pulpers, specifically to a ventilation and deodorization mechanism for a pulper. Background Technology

[0002] In the pulping process, the pulper is an important piece of equipment. During operation, the equipment generates dust and odor. The dust mainly comes from the decomposition of waste paper, while the odor mainly comes from the decomposition of paper fibers, microbial activity, and chemical additives. These factors can cause many harms to the environment and human health, thus requiring ventilation during the production process.

[0003] To address the aforementioned deficiencies, existing technology (Chinese Patent No. CN219752837U, published on 2023-09-26) provides an exhaust system for a pulper under a paper machine. By incorporating components such as a fan, exhaust pipe, drain pipe, and water seal trough, this system effectively removes the heat generated during pulper operation. This significantly reduces the amount of heat at the pulper inlet and weakens the airflow, ensuring that the paper web can fall smoothly into the pulper and guaranteeing its normal operation. It also provides a safer working environment for operators.

[0004] During the use of the above solution, the fan needs to be turned on and off manually. After the fan is started, it only vents the airflow, but the odor generated during the processing is not treated in time. It will be discharged with the airflow, thus polluting the air. Utility Model Content

[0005] The purpose of this utility model is to provide a ventilation and deodorization mechanism for a pulper, so as to solve the problem mentioned in the background art that the ventilation and deodorization mechanism of the existing pulper requires manual opening and closing during use, and the fan only vents the airflow after it is started, while the odor generated during the processing is not treated in time and will be discharged with the airflow, thus causing air pollution.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a deodorization mechanism for a pulper, comprising a pulper body, a gas outlet provided on the top right side of the pulper body, the gas outlet being connected to a suction pipe, a fan installed in the suction pipe, and an odor sensor provided in the middle section of the suction pipe, the right side of the suction pipe being connected to a port on the top of a processing box, and an exhaust pipe provided on the bottom right side of the processing box;

[0007] The top of the treatment box is symmetrically equipped with storage tanks, and the bottom of the storage tanks is integrally equipped with liquid outlet pipes. The liquid outlet pipes are symmetrically arranged through the top of the treatment box. The top inner side of the treatment box is equipped with an adaptive liquid outlet component, and the adaptive liquid outlet component adjusts the output of deodorant according to the size of the exhaust fan.

[0008] The processing box is equipped with a uniform mixing component, which ensures that the discharged odor gas and deodorizing agent come into uniform contact.

[0009] Furthermore, the exhaust fan in the exhaust pipe extracts the odor from inside the pulper body, the odor sensor detects the concentration of the emitted odor, and a control panel is provided on the front side of the pulper body. When the odor concentration exceeds the set value, the control system automatically increases the amount of deodorant sprayed and increases the speed of the exhaust fan to enhance the deodorization effect.

[0010] Furthermore, the adapter liquid outlet assembly includes a toothed ring rotatably connected to the top of the inner side of the treatment tank via ball bearings. A fan blade is integrally installed in the middle of the toothed ring, and the fan blade is positioned directly opposite the inlet. After ventilation of the inlet, the fan blade drives the toothed ring to rotate synchronously.

[0011] Furthermore, the outer side of the gear ring is symmetrically connected to gears, which are rotatably connected to the top of the inner side of the processing tank via ball bearings, and the gears are symmetrically provided with first liquid outlets.

[0012] Furthermore, a second outlet is symmetrically provided at the bottom of the outlet pipe, and a sealed bearing connects the bottom of the outlet pipe to the top of the gear. The second outlet intermittently overlaps with the first outlet.

[0013] Furthermore, the uniform mixing component includes a diversion column installed in the middle of the inner side of the processing box, the top of the diversion column is configured as an umbrella-shaped structure, and the top of the diversion column is directly opposite the bottom of the opening.

[0014] Furthermore, a flow guide plate is installed on the inner wall of the processing box. The flow guide plate is configured with a spiral structure, and the flow guide plate and the flow splitting column constitute a uniform mixing structure for flow splitting and guiding.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The odor extraction and deodorization mechanism of this pulper works in concert through three core mechanisms: odor detection, appropriate agent supply, and uniform mixing. This enables automated extraction and precise deodorization of odor generated by the pulper, solving the problems of untimely deodorization, agent waste, and uneven mixing in traditional mechanisms.

[0017] 1. Furthermore, the operation of the exhaust fan generates negative pressure, which draws the odorous gas from the gas outlet at the top right side of the pulper body into the exhaust pipe, forming a directional airflow. The airflow is transported along the exhaust pipe to the opening at the top of the treatment box and enters the deodorization treatment stage. The odor sensor in the middle section of the exhaust pipe detects the odor concentration in the airflow in real time.

[0018] 2. Furthermore, when the exhaust airflow enters the treatment box, the airflow impacts the fan blades. The stronger the wind force, the greater the volume of odorous air, and the faster the fan blade speed. The rotation frequency of the gear ring increases, and the gear ring drives the gear to rotate synchronously. The first liquid outlet symmetrically opened on the gear intermittently overlaps with the second liquid outlet of the liquid outlet pipe. The faster the gear speed, that is, the stronger the exhaust air force, the higher the frequency of overlap between the first and second liquid outlets. The more deodorant flows from the storage tank through the liquid outlet pipe and the overlapping liquid outlets into the treatment box, the more deodorant is output accordingly.

[0019] 3. Furthermore, after the odorous gas enters the treatment chamber, it impacts the umbrella-shaped top and is dispersed into multiple streams. This prevents the gas from concentrating and causing insufficient contact of the deodorant in certain areas. The deodorant is also initially dispersed by the umbrella-shaped structure and forms a preliminary mixture with the streams. The spiral guide plate and the diversion column form a synergistic diversion and guiding structure. The gas-liquid mixture dispersed by the diversion column flows downward along the channel of the spiral guide plate. The spiral path significantly extends the residence time of the gas and liquid in the treatment chamber. At the same time, the gas flow rotates in the channel, driving the deodorant and odor to be fully mixed, ensuring that each part of the odor can come into contact with and react with the deodorant, avoiding the problem of untreated odor being directly discharged.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: Please refer to Figure 1 - Figure 2 This utility model provides the following technical solution: a deodorizing mechanism for a pulper, comprising a pulper body 1, a gas outlet at the top right side of the pulper body 1, the gas outlet being connected to a suction pipe 2, a suction fan 6 installed in the suction pipe 2, and an odor sensor 7 installed in the middle section of the suction pipe 2, the right side of the suction pipe 2 being connected to a port 4 at the top of a treatment box 3, an exhaust pipe 5 at the bottom right side of the treatment box 3, storage tanks 8 symmetrically arranged at the top of the treatment box 3, an outlet pipe 9 integrally installed at the bottom of the storage tank 8, the outlet pipe 9 being symmetrically arranged through the top of the treatment box 3, an adaptive outlet component at the top inner side of the treatment box 3, and the adaptive outlet component adjusting the output of the deodorizing agent according to the suction force, and a uniform mixing component inside the treatment box 3, the uniform mixing component ensuring uniform contact between the discharged odor and the deodorizing agent.

[0029] refer to Figure 1 - Figure 2 As shown, during operation, when the pulper body 1 is working, the control system sends a signal to the exhaust fan 6 in the exhaust pipe 2. The exhaust fan 6 draws the odor into the treatment box 3. During this process, the deodorant matching liquid dispensing component starts synchronously, dispensing a relative amount of deodorant to ensure that the odor generated by the pulper body 1 can be collected and treated in a timely manner. The odor sensor 7 can detect the odor concentration inside the exhaust pipe 2. When the odor concentration exceeds the set value, the control system automatically increases the speed of the exhaust fan 6 to enhance the deodorization effect; conversely, it reduces the speed of the exhaust fan 6, and the pulper body 1 stops. After operation, the control system will delay shutting down the exhaust fan 6 for a period of time, and the deodorizing agent dispensing component will also be delayed to ensure that the residual odor gas around the pulper body 1 is completely collected and treated. The odor gas and deodorizing agent entering the treatment box 3 are evenly mixed under the action of the uniform mixing component, and then discharged from the exhaust pipe 5 at the bottom of the treatment box 3. Through the coordinated operation of the three core mechanisms of exhaust detection, agent supply and uniform mixing, the automatic extraction and precise deodorization of the odor generated by the pulper are realized, solving the problems of untimely deodorization, agent waste and uneven mixing in traditional mechanisms.

[0030] Example 2:

[0031] Based on Example 1, an odor extraction and concentration detection mechanism is also disclosed to capture and monitor odor in real time. Please refer to [link / reference]. Figure 1 - Figure 3 As shown, its specific structure is as follows: the exhaust fan 6 in the exhaust pipe 2 extracts the odor from inside the pulper body 1, the odor sensor 7 detects the concentration of the discharged odor, and a control panel is set on the front side of the pulper body 1. When the odor concentration exceeds the set value, the control system automatically increases the amount of deodorant sprayed and increases the speed of the exhaust fan 6 to enhance the deodorization effect.

[0032] refer to Figure 1 - Figure 3 As shown, during operation, the exhaust fan 6 installed in the exhaust pipe 2 is started. The operation of the exhaust fan 6 generates negative pressure, which draws the odor from the gas outlet at the top right side of the pulper body 1 into the exhaust pipe 2, forming a directional airflow to prevent the odor from spreading to the workshop environment. The airflow is transported along the exhaust pipe 2 to the opening 4 at the top of the treatment box 3 and enters the deodorization treatment stage. The odor sensor 7 in the middle section of the exhaust pipe 2 detects the odor concentration in the airflow in real time and transmits the data to the control panel on the front side of the pulper body 1. When the concentration exceeds the set threshold, the control system automatically triggers dual adjustment. On the one hand, it increases the amount of deodorant sprayed, and on the other hand, it increases the speed of the exhaust fan 6. By enhancing the exhaust intensity and the supply of chemicals, it ensures that the high concentration of odor is fully treated. If the concentration is below the threshold, the basic exhaust and chemical supply are maintained to avoid energy and chemical waste.

[0033] Example 2:

[0034] Based on Example 1, a mechanism for adapting the liquid dispensing component is also disclosed, which dynamically adjusts the deodorant output according to the exhaust fan speed. Please refer to [link / reference needed]. Figure 5 - Figure 6 As shown, its specific structure is as follows: The adapter liquid outlet assembly includes a gear ring 12 that is rotatably connected to the top of the inner side of the treatment tank 3 via ball bearings. A fan blade 13 is integrally installed in the middle of the gear ring 12. The fan blade 13 is set directly opposite the opening 4. After the opening 4 is ventilated, the fan blade 13 drives the gear ring 12 to rotate synchronously. A gear 14 is symmetrically meshed on the outer side of the gear ring 12. The gear 14 is rotatably connected to the top of the inner side of the treatment tank 3 via ball bearings. A first liquid outlet 15 is symmetrically opened on the gear 14. A second liquid outlet 16 is symmetrically opened at the bottom of the liquid outlet pipe 9. The bottom of the liquid outlet pipe 9 is connected to the top of the gear 14 by a sealed bearing. The second liquid outlet 16 and the first liquid outlet 15 intermittently overlap.

[0035] refer to Figure 5 - Figure 6As shown, during use, the adapter liquid dispensing component utilizes the kinetic energy of the exhaust airflow to drive the mechanical structure, achieving dynamic matching between the deodorant output and the odor volume, thus avoiding excessive or insufficient dosage. The toothed ring 12, connected to the inner top of the treatment chamber 3 via ball bearings, has a centrally integrated fan blade 13 facing the inlet 4. When the exhaust airflow enters the treatment chamber 3 through the inlet 4, the airflow impacts the fan blade 13, causing it to rotate synchronously with the toothed ring 12. The greater the exhaust force, i.e., the greater the odor volume, the faster the fan blade 13 rotates, and the higher the rotation frequency of the toothed ring 12. The outer sides of the toothed ring 12 are symmetrically meshed. The connected gear 14 is connected to the top of the treatment box 3 by ball bearings and rotates synchronously with the gear ring 12. The first liquid outlet 15 symmetrically opened on the gear 14 intermittently overlaps with the second liquid outlet 16 of the liquid outlet pipe 9 at the bottom of the storage tank 8. The faster the gear 14 rotates, that is, the stronger the suction force, the higher the frequency of overlap between the first liquid outlet 15 and the second liquid outlet 16. The more deodorant flows from the storage tank 8 through the liquid outlet pipe 9 and the overlapping liquid outlet into the treatment box 3, the more deodorant flows. Conversely, the weaker the suction force, the lower the overlap frequency and duration, and the less liquid is discharged, thus achieving adaptive adjustment of the greater the air volume and the more deodorant is supplied.

[0036] Example 4:

[0037] Based on Example 3, a uniform mixing component mechanism is also disclosed to ensure sufficient contact and reaction between the odorant and the deodorant. Please refer to [link / reference]. Figure 3 - Figure 4 As shown, its specific structure is as follows: The uniform mixing component includes a diversion column 10 installed in the middle of the inner side of the processing box 3. The top of the diversion column 10 is set as an umbrella-shaped structure. The top of the diversion column 10 is directly opposite the bottom of the opening 4. A guide plate 11 is installed on the inner wall of the processing box 3. The guide plate 11 is set as a spiral structure. The guide plate 11 and the diversion column 10 constitute a uniform mixing structure for diversion and diversion.

[0038] refer to Figure 3 - Figure 4As shown, during use, the uniform mixing component, through its diversion and guiding structure, prolongs the contact time and expands the contact area between the odor and the deodorant, ensuring the deodorization effect. The diversion column 10 installed in the middle of the inner side of the treatment box 3 has an umbrella-shaped top, directly facing the bottom of the inlet 4. The odor airflow entering from the inlet 4 first impacts the top of the umbrella shape and is dispersed into multiple streams, preventing concentrated airflow from causing insufficient contact with the deodorant in certain areas. Simultaneously, the deodorant dripping from the matching liquid outlet component is also initially dispersed by the umbrella-shaped structure, forming a preliminary mixture with the streams. Treatment box 3... The spiral guide plate 11 installed on the inner wall forms a synergistic flow diversion and guiding structure with the diversion column 10. The gas-liquid mixture dispersed by the diversion column 10 flows downward along the channel of the spiral guide plate 11. The spiral path greatly extends the residence time of the gas and liquid in the treatment box 3. At the same time, the airflow rotates in the channel, driving the deodorizer and odor to be fully stirred, ensuring that each part of the odor can come into contact with the deodorizer and react, avoiding the problem of untreated odor being directly discharged. Finally, the clean gas that has completed the mixing reaction is discharged from the exhaust pipe 5 at the bottom right side of the treatment box 3, achieving the standard emission.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
