Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical equipment, and in particular to a TPV material deodorization device that prevents backflush. Background Technology
[0002] During the production of TPV materials, deodorization treatment is carried out to effectively control the odor of the materials. After the deodorization is completed, the materials are cooled by blowing air into the silo. When the cooling fan replenishes the cold air, some materials will enter the deodorization barrel through the discharge pipe and remain in the heating pipe. When heating is carried out again, the materials will come into direct contact with the heating pipe at high temperature and flammability, which may introduce a fire into the deodorization barrel, posing a great safety hazard. Utility Model Content

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0042] Reference Figures 1 to 3 This utility model discloses a TPV material deodorization device with anti-backflush mechanism, comprising a heating component 1, a cooling component, and an anti-backflush component 3.
[0043] Heating component 1 includes a heating device, which contains TPV material and is used to heat the TPV material. A discharge port 16 is provided at the bottom of the heating device.
[0044] The cooling assembly includes a cooling tank 21 and a feeding pipe 4. The cooling tank 21 has a feeding port, and the two ends of the feeding pipe 4 are connected to the discharge port 16 and the feeding port, respectively, so that the TPV material falls from the discharge port 16 into the feeding port.
[0045] The anti-backflush component 3 has an umbrella-shaped inverted cone structure. The anti-backflush component 3 is located in the cooling tank 21 near the bottom of the feed inlet. TPV material falls from the feed inlet onto the anti-backflush component 3 and falls into the cooling tank 21 along the edge of the anti-backflush component 3.
[0046] In this embodiment, the heating component 1 is used to deodorize TPV materials. It includes a heating device with an internal space for holding the TPV materials. The heating device heats the TPV materials to remove odor components. A discharge port 16 is provided at the bottom of the heating device. The size of the discharge port 16 is designed to ensure that the heated TPV materials can fall smoothly while avoiding blockage or excessive leakage. The edges of the discharge port 16 are rounded to prevent material residue from being scraped during descent, which could affect subsequent deodorization processes.
[0047] Specifically, in one embodiment of this application, the heating device is a sealed cavity structure made of a high-temperature and corrosion-resistant metal material, such as 316L stainless steel, to ensure stability and durability under prolonged high-temperature environments. Its internal space is configured according to the amount of TPV material to be processed, ensuring uniform heating and facilitating sufficient circulation of hot air between materials, thereby improving heating efficiency.
[0048] A centrifugal fan is selected as the power source for the hot air. In this embodiment, the heating device processes 500 kg of TPV material per hour. Based on the size of the heating device and the required hot air flow rate, a centrifugal fan with an air volume of 2000-3000 cubic meters per hour and an air pressure of 1000-1500 Pascals is selected to ensure that a sufficiently strong and stable airflow is generated to deliver the hot air. The fan motor is a variable frequency speed control motor, which can flexibly adjust the fan speed according to the actual heating requirements, thereby precisely controlling the flow rate and velocity of the hot air.
[0049] Electric heating elements are installed at the air outlet of the fan. These elements are made of high-temperature resistant and efficient nickel-chromium alloy, and their total power can be set between 50-100 kilowatts. By arranging multiple heating elements in reasonable groups, with each group equipped with an independent temperature control switch, zoned heating control can be easily achieved, avoiding localized overheating and ensuring uniform hot air temperature. The heating elements are wrapped with an insulating and thermally conductive material, such as magnesium oxide ceramic powder, which effectively transfers heat to the flowing air while ensuring electrical safety and preventing electric leakage accidents.
[0050] An air filter is installed at the fan inlet. This filter employs a multi-layered structure, including a pre-filter metal mesh to intercept large particles and a medium-efficiency fiber mesh to further filter fine dust, ensuring clean air entering the heating system and preventing impurities from contaminating the TPV materials and affecting their quality. Simultaneously, an air preheating device is installed before the air enters the heating tubes. This device utilizes waste heat generated during system operation (such as waste heat from the cooling components) to preheat the air, improving energy efficiency and reducing overall energy consumption. The preheating device can be a heat exchanger, which uses pipes to exchange heat between cold air and a heat medium (such as warm coolant from the cooling components or other waste heat media), raising the air temperature to approximately 30℃-50℃ before it enters the heating tubes for further heating.
[0051] Hot air inlets and outlets are strategically placed at different locations on the bottom, top, and sides of the heating device to form a complete hot air circulation channel. The hot air inlets connect to the outlets of the hot air generation system, and hot air is evenly delivered to all corners of the heating device through pipes. To ensure more even distribution of hot air among the materials, guide vanes are installed at the hot air inlets. The angle and shape of the guide vanes have been optimized through simulation to disperse the hot air into multiple airflows in different directions, preventing direct impact of hot air on the materials and avoiding localized overheating or material scattering. Return air ducts are connected to the hot air outlets on the top and sides of the heating device to return some of the hot air that has undergone heat exchange to the hot air generation system for reheating and recycling, improving energy efficiency and helping to maintain temperature stability and uniform hot air distribution within the heating device.
[0052] The discharge port 16 is located at the center of the bottom of the heating device. It is circular, and its diameter depends on the material flow rate and particle size. In this embodiment, the TPV material is generally 5-10 cm. A discharge valve 15 is installed at the discharge port 16. The discharge valve 15 is linked to the control system of the heating device. According to the set heating time (30-60 minutes in this embodiment), it is flexibly adjusted according to the material quantity and initial odor level. The valve automatically opens after the material reaches the set deodorization temperature and is maintained for a certain period of time, achieving timed and quantitative material discharge. The inner wall of the discharge port 16 is polished, with a roughness Ra value of less than 0.8 μm, to minimize friction and residue during material fall and ensure that the material smoothly enters the cooling components of the next stage.
[0053] In one feasible embodiment, temperature sensors, such as thermocouple temperature sensors, are installed at multiple key locations inside the heating device, evenly distributed near the material placement racks on each layer, as well as at the hot air inlet and outlet. The temperature sensors collect temperature data in real time and feed it back to the control system. Based on a preset temperature range (in this embodiment, according to the characteristics of TPV materials), the control system sets the heating temperature between 150℃ and 200℃. By adjusting the fan speed in the hot air generation system and the power of the electric heating element, precise control of the hot air temperature and flow rate within the heating device is achieved, ensuring that the TPV materials are heated and deodorized under suitable temperature conditions, achieving a good deodorization effect. Simultaneously, a temperature display instrument is installed on the outer wall of the heating device, allowing operators to visually monitor the approximate temperature inside the device.
[0054] The cooling assembly mainly consists of a cooling tank 21 and a feed pipe 4. The cooling tank 21 has good heat insulation performance, and its internal structure helps to dissipate heat evenly from the TPV material. The tank wall is made of a material with moderate thermal conductivity to ensure the stability of the cooling effect. A feed inlet is provided at the top of the cooling tank 21, and the position and size of the feed inlet are adapted to the subsequent feed pipe 4 and the entire material transfer process.
[0055] Specifically, in this embodiment, the cooling tank 21 has a double-layer structure. The outer layer is made of ordinary carbon steel, and the inner layer is made of stainless steel 304, forming a sealed cooling chamber between the two layers. The top of the cooling tank 21 is designed as a dome, which helps to reduce heat accumulation. The feed inlet is located at an off-center position of the dome, and its diameter matches that of the feed pipe 4, typically 8-12 cm. The ratio of the tank height to its diameter is reasonably determined based on factors such as cooling efficiency and available space. In this embodiment, the height is 1.5-2 times the diameter to ensure that the material has sufficient residence time in the tank for cooling. The bottom is conical to facilitate the concentrated discharge of cooled material. A discharge port is located at the lowest point of the cone, and the discharge port is also equipped with a discharge valve to control the discharge as needed.
[0056] The cooling chamber is connected to an external cooling circulation system 22 via pipes. The cooling circulation system 22 consists of a refrigeration unit, a circulating pump, a coolant storage tank, and a temperature control device. The refrigeration unit uses a compressor refrigeration principle to provide a stable low-temperature coolant (such as an ethylene glycol aqueous solution, with a temperature adjustable from 5℃ to 15℃). The circulating pump delivers the coolant to the cooling chamber of the cooling tank 21, allowing it to circulate within the chamber and remove the heat dissipated by the material, thus achieving a cooling effect. The temperature control device can monitor the coolant temperature in real time and automatically adjust the operating power of the refrigeration unit according to the set value to ensure that the coolant temperature remains stable within a suitable range.
[0057] The feed pipe 4 is made of high-temperature resistant and smooth inner wall material to reduce resistance and adhesion of materials during transmission. Both ends of the feed pipe 4 are connected to the discharge port 16 of the heating device and the feed port of the cooling tank 21, respectively. The connections are secured with high-sealing connectors to prevent leakage or the ingress of outside air during material transmission, ensuring that the TPV material can smoothly fall from the discharge port 16 into the feed port 4.
[0058] Specifically, the feed pipe 4 is made of high-temperature resistant, wear-resistant, and smooth-walled polytetrafluoroethylene (PTFE) pipe. Its inner diameter is determined according to the material flow rate and velocity requirements, generally 6-10 cm, and the wall thickness is 3-5 mm to ensure the strength and durability of the pipe. Both ends of the pipe are connected to the discharge port 16 of the heating device and the feed port of the cooling tank 21 through flange connections. High-temperature resistant rubber gaskets are installed between the flanges to ensure a tight seal at the connection points, preventing hot air leakage and the ingress of outside air.
[0059] To reduce heat loss during material transport, the feed pipe 4 is wrapped with insulation material, such as rock wool insulation pipe, with an insulation layer thickness of approximately 3-5 cm. This reduces the rate of heat dissipation, ensuring that the material remains within a suitable temperature range when entering the cooling tank 21, which is beneficial for subsequent cooling and deodorization. Simultaneously, pipe supports are installed at regular intervals along the pipe's length (e.g., every 1-1.5 meters). These supports are made of metal and secured to the ground with anchor bolts to ensure pipe stability and prevent deformation or displacement due to gravity or thermal expansion and contraction.
[0060] The anti-backflush component 3 is a crucial part ensuring the stable operation of the device. It features an umbrella-shaped inverted cone structure, made of robust and heat-resistant material, and is positioned below the feed inlet inside the cooling tank 21. Its installation location was determined through multiple tests to achieve optimal anti-backflush performance. After TPV material falls from the feed inlet, it first lands on the anti-backflush component 3. Due to its unique umbrella-shaped inverted cone structure, the material naturally slides along its edges, evenly dispersing into the cooling tank 21. Furthermore, the surface of the anti-backflush component 3 has a textured finish, which guides the material's smooth flow while preventing material accumulation on its surface, further ensuring the continuous and efficient operation of the entire deodorization device.
[0061] Specifically, the umbrella-shaped inverted cone structure of the anti-backflush component 3 has a cone apex angle typically designed between 120° and 150° to allow materials to slide smoothly along the edge. It is made of high-strength, high-temperature resistant engineering plastics (such as polyetheretherketone, PEEK). This material not only possesses excellent high-temperature resistance (withstanding temperatures above 200°C) but also exhibits good chemical stability, making it less prone to chemical reactions with TPV materials. Its top is fixed to a support crossbar inside the cooling tank 21 via welding or bolting. The support crossbar, made of stainless steel, spans a suitable position below the inlet of the cooling tank 21, ensuring that the anti-backflush component 3 is securely installed and in a stable horizontal state.
[0062] The surface of the anti-backflush component 3 is frosted, with a roughness Ra value controlled between 1.6 and 3.2 μm. This increases the friction between the material and the surface, allowing it to slide along the edge, while preventing the material from accumulating in one place due to excessive smoothness. Simultaneously, a downward-sloping guide groove is designed around the edge of the anti-backflush component 3. The guide groove is 2-3 cm wide and 1-1.5 cm deep, guiding the material to fall more evenly into different locations within the cooling tank 21, preventing material accumulation in localized areas and affecting the cooling effect. Furthermore, this structure effectively blocks any reverse airflow that may occur within the cooling tank 21, preventing the airflow from blowing material that has just entered the cooling tank 21 back into the feed pipe 4, thus ensuring unidirectional material transport and stable operation of the device.
[0063] Continue to refer to Figure 2In one feasible embodiment, the heating assembly 1 includes a odor dispersing bin 11 and a heating element 12. TPV material is disposed within the odor dispersing bin 11, which is equipped with a stirring device to ensure uniform heating of the TPV material. The heating element 12 is disposed on one side of the odor dispersing bin 11 and connected to it via a heat delivery pipe 124 for supplying hot air to the odor dispersing bin 11. A hot air generating unit 121, including a resistance wire and a filter element 123, is used to heat air to form hot air to be supplied to the odor dispersing bin 11. The filter element 123 is used to filter the hot air. A conveying unit 122 includes a fan that draws in hot air, which, after being filtered by the filter element 123, is delivered to the odor dispersing bin 11 via the heat delivery pipe 124. A temperature detection unit, located inside the odor dispersing bin 11, is used to detect the temperature inside the bin 11 and the surface temperature of the TPV material. A flow detection unit, located inside the heating pipe 124, is used to detect the airflow of hot air from the fan into the odor dispersing bin 11. The system also includes a first circulation assembly for circulating and heating the TPV material inside the odor dispersing bin 11. The top of the odor dispersing bin 11 has a first through-hole. The first circulation assembly includes: a first circulation duct 14, whose two ends are connected to the first through-hole and the discharge port 16, respectively, for discharging the TPV material from the odor dispersing bin 11 from the discharge port 16 along the first circulation duct 14 and through the first through-hole into the odor dispersing bin 11; and a first feeding fan 13, located at the top of the odor dispersing bin 11 and connected to the first circulation duct 14, which evacuates the first circulation duct 14 to create negative pressure, for drawing the TPV material into the first circulation duct 14. The bottom of the odor dispersing bin 11 has an inverted conical structure, and the discharge port 16 is located at the center of the bottom of the odor dispersing bin 11. A first opening 111 is provided on the side wall of the bottom of the odor dispersing bin 11 near the discharge port 16, and one end of the first circulating air duct 14 is connected to the first opening 111.
[0064] In this embodiment, the odor dispersing bin 11 is made of 316L stainless steel, which is resistant to high temperatures and corrosion and has good heat insulation properties, to ensure stable and reliable operation under long-term high-temperature environments and reduce heat loss. The wall thickness of the bin is determined according to the size of the odor dispersing bin 11 and the pressure requirements, and is generally between 8-12 mm. The top of the bin is a dome-shaped design, which facilitates better circulation of materials and hot air inside. At the same time, multiple openings for installing related components and operation and maintenance ports are opened in the dome. The operation and maintenance ports are equipped with sealing caps for easy daily inspection and maintenance. The bottom is inverted cone-shaped, and a discharge port 16 is opened at the center of the cone bottom. The diameter of the discharge port 16 is set according to factors such as material flow rate and particle size, usually 5-10 cm. The edges of the discharge port 16 are rounded, and the inner wall is smooth with a roughness Ra value of less than 0.8 μm, which facilitates the smooth falling of materials and avoids residue accumulation.
[0065] The stirring device is installed on the central axis inside the odor dispersing tank 11 and consists of a stirring shaft and stirring blades. The stirring shaft is made of high-strength stainless steel, and its diameter is determined according to the size of the odor dispersing tank 11 and the torque required for stirring, generally 5-10 cm. It can withstand various forces during the stirring process to ensure stable operation. The stirring blades adopt a spiral structure and are made of wear-resistant and high-temperature resistant engineering plastics (such as polytetrafluoroethylene modified materials) or metal materials (such as stainless steel 304 with a wear-resistant coating). There are 3-5 sets of blades, and the tilt angle of each set of blades has been optimized through fluid dynamics simulation to ensure that the TPV material can be fully agitated during rotation, so that the material is heated evenly in the hot air environment, avoiding local overheating or underheating. The top of the stirring shaft is connected to the drive motor via a coupling. The drive motor is a variable frequency speed control motor, and its power is determined according to the volume of the odor dispersing bin 11 and the characteristics of the material. For example, for an odor dispersing bin 11 with a volume of 2-3 cubic meters, the power of the drive motor can be between 3-5 kilowatts. The motor speed can be flexibly adjusted according to the material turning during the actual heating process, thereby controlling the stirring speed and achieving the best stirring effect.
[0066] The outer shell of the heating element 12 is made of carbon steel, with an internal insulation layer made of rock wool or aluminum silicate fiber cotton, about 10-15 cm thick, to effectively reduce heat loss to the external environment. The heating element and related airflow guiding structure are installed inside. The overall shape is rectangular, and its dimensions are rationally designed based on factors such as the required hot air volume and hot air output pressure of the odor dissipation bin 11.
[0067] The filter element 123 is installed on the channel through which hot air flows out of the heating component 12. It employs a multi-layer filtration structure to ensure comprehensive and effective filtration of the hot air. The outermost layer is a coarse metal mesh with a mesh size between 1-2 mm, primarily intercepting large particles such as dust and rust. The middle layer is a medium-efficiency fiber mesh, woven from materials such as glass fiber or polyester fiber, which effectively filters particles with a diameter of 1-10 micrometers. The innermost layer is a high-efficiency activated carbon filter, utilizing the porous structure of activated carbon to adsorb odor molecules, oil, and other impurities that may be present in the hot air, further purifying the air and preventing impurities from contaminating the TPV material and affecting its quality. The filter element 123 has a drawer-type or clamp-type structure, facilitating regular disassembly for cleaning or replacement of the filter element, ensuring continuous filtration performance.
[0068] A centrifugal fan is selected, and its air volume, air pressure, and other parameters are determined comprehensively based on factors such as the volume of the odor dispersing bin 11, the hot air circulation requirements, and the pipeline resistance of the entire system. For example, for the aforementioned requirements of the odor dispersing bin 11 and hot air parameters, a centrifugal fan with an air volume of 1000-2000 cubic meters per hour and an air pressure of 800-1200 Pascals can be selected. The fan impeller is made of high-quality aluminum alloy and manufactured through precision casting, featuring light weight, high strength, and low rotational inertia, ensuring the stability and reliability of the fan during high-speed rotation. The fan motor is an explosion-proof, variable frequency speed-regulating motor with good overload protection and heat dissipation performance. The fan speed can be flexibly adjusted according to actual operating conditions to precisely control the flow rate and pressure of the hot air, while meeting safety production requirements and preventing safety accidents caused by electrical faults.
[0069] The heat supply pipe 124 is made of galvanized iron or stainless steel sheet, which is resistant to high temperatures and corrosion and has good thermal insulation properties. The inner diameter of the pipe is designed according to the requirements of hot air flow rate and velocity, generally between 20-30 cm, and the wall thickness is 2-3 mm to ensure the strength and sealing of the pipe. The pipe connection is made by flange connection, and high-temperature resistant rubber sealing gaskets are installed between the flanges and tightened with bolts to ensure a tight connection and prevent hot air leakage. The outer layer of the pipe is wrapped with thermal insulation material, such as rubber and plastic sponge insulation pipe, with an insulation layer thickness of about 5-8 cm, to reduce heat loss of hot air during transportation and to ensure that the hot air is delivered to the odor dissipation container 11 at a relatively stable temperature.
[0070] The temperature detection unit has multiple detection points inside the odor dispersing bin 11, including at different heights of the material accumulation layer (such as at 1 / 3, 1 / 2, and 2 / 3 of the height from the bottom of the bin) and in key areas near the hot air inlet and outlet. The temperature sensor used is a thermocouple sensor, which has advantages such as fast response speed, high measurement accuracy, and high temperature resistance. The sensor probe is encapsulated in a stainless steel shell to ensure stable operation in high-temperature environments for extended periods, accurately measuring the temperature inside the odor dispersing bin 11 and the surface temperature of the TPV material. The temperature sensor is connected to the control system via a signal line, transmitting the real-time temperature data to the control system. The control system adjusts and controls the heating element 12, fan, and other related equipment according to a preset temperature range (e.g., setting the upper and lower limits of the heating temperature to 150℃ and 200℃ respectively based on the characteristics of the TPV material), ensuring that the odor dispersing bin 11 maintains a suitable heating temperature at all times, achieving effective deodorization of the material.
[0071] The flow detection unit is installed inside the heat supply pipe 124, using a vortex flow meter to detect the volume of hot air delivered by the fan into the odor dispersing bin 11. The vortex flow meter operates based on the Karman vortex street principle, featuring a rationally designed internal structure, a stainless steel main body, and the ability to withstand high-temperature environments. It also boasts high precision, a wide range, and strong anti-interference capabilities. During installation, the lengths of the preceding and following straight pipe sections must meet the specified standards (generally, the length of the preceding straight pipe section should not be less than 10 times the pipe diameter, and the length of the following straight pipe section should not be less than 5 times the pipe diameter) to ensure measurement accuracy. The flow detection unit transmits the real-time detected airflow data to the control system. The control system, based on the set hot air flow parameters (such as setting a suitable airflow range according to the material quantity and heating uniformity requirements in the odor dispersing bin 11), controls the hot air delivery flow rate by adjusting the fan speed, ensuring that the hot air circulates within the odor dispersing bin 11 at a suitable flow rate, guaranteeing uniform heating of the material.
[0072] The first circulating duct 14 is made of a high-temperature resistant, corrosion-resistant, and smooth-walled material similar to the heat supply duct 124, such as stainless steel. Its inner diameter is determined based on the material's conveying capacity and flow rate requirements, generally between 15-25 cm, to ensure smooth material circulation. Both ends of the duct are securely connected to the first through-hole at the top and the discharge port 16 at the bottom of the odor dispersing container 11 via welding or flange connections. The connections are sealed to prevent material leakage and hot air escape. To reduce frictional resistance within the duct, the inner wall is polished to a roughness Ra value of less than 0.8 μm. Openable cleaning ports are installed at appropriate locations within the duct (e.g., every 1-1.5 meters) to facilitate regular cleaning of any material residue that may adhere to the inner wall, ensuring unobstructed flow.
[0073] The first feeding blower 13 is installed on top of the odor dispersing bin 11 and connected to the first circulating air duct 14. A Roots blower is selected as the power source. Roots blowers are characterized by stable flow rate, wide pressure range, and strong adaptability to media, making them suitable for pumping materials for circulating transport. Based on the length and diameter of the first circulating air duct 14, as well as the material conveying resistance, a suitable model of Roots blower is selected. For example, for circulating air ducts of the above dimensions and conventional TPV material conveying, a Roots blower with an air volume of 500-1000 cubic meters per hour and an air pressure of 3000-5000 Pascals can be selected. Silencers are installed at the blower's inlet and outlet to reduce noise during operation, and vibration damping pads are also provided to reduce the impact of blower vibration on the entire device. The first feeding fan 13 creates a negative pressure environment in the first circulating air duct 14 by drawing a vacuum, thereby drawing the TPV material in the odor dispersing bin 11 into the air duct. The material then returns to the first through hole at the top of the odor dispersing bin 11 along the air duct through the discharge port 16 and falls back into the bin, achieving circulating heating of the material and further improving the uniformity of heating and deodorization effect.
[0074] The entire device is equipped with a control system that enables centralized operation, monitoring, and management of all units and components through a human-machine interface. Operators can easily set parameters such as heating temperature, hot air flow rate, stirring speed, and material circulation time on the interface. The control system automatically coordinates the operation of the heating element 12, fan, stirring device, and first feeding fan 13 based on the set parameters, ensuring close cooperation between all components to achieve optimal deodorization. Simultaneously, the control system displays real-time operating data such as temperature and airflow from the temperature and flow detection units for each key component. In case of any abnormalities (such as excessively high or low temperature, insufficient airflow, or equipment malfunction), the system immediately issues an audible and visual alarm and clearly displays the fault location and related information on the human-machine interface, facilitating quick and accurate troubleshooting and resolving issues, and ensuring the safe, stable, and efficient operation of the device.
[0075] In one feasible embodiment, two odor dispersing bins 11 are provided, namely odor dispersing bin 11A and odor dispersing bin 11B, both made of high-temperature and corrosion-resistant 316L stainless steel with a wall thickness of 8-10mm to ensure structural stability in high-temperature environments. Each odor dispersing bin 11 has multiple layers of material placement racks inside, made of perforated stainless steel plates with holes of 3-5mm in diameter, which ensures both hot air circulation and prevents materials from falling. The racks are spaced 200-300mm apart to facilitate uniform heating of the materials.
[0076] Both odor dispersing bins 11 have a first through hole at the top for connecting to the first circulation component; the bottom has a discharge port 16 with a diameter of 80-120mm, which is equipped with an electric valve and the material discharge is precisely controlled by the control system.
[0077] In one feasible embodiment, a discharge valve 15 is provided at the connection between the discharge port 16 and the feed pipe 4, and the discharge valve 15 is used to control the opening and closing of the feed pipe 4.
[0078] In this embodiment, the discharge valve 15 adopts an electric butterfly valve structure. Its valve body is made of 304 stainless steel, possessing excellent high-temperature resistance and corrosion resistance, enabling it to adapt to the high-temperature environment at the discharge port 16 of the bulk odor container 11 and the possible material components it may come into contact with. The valve plate of the discharge valve 15 is also made of stainless steel, with its thickness determined reasonably according to the valve diameter and pressure resistance, generally between 5-10 mm. The surface is polished to reduce friction when in contact with materials, ensuring smooth valve opening and closing and preventing material residue. The valve plate is connected to the electric actuator via a valve stem. The valve stem is made of high-strength stainless steel, possessing sufficient strength and rigidity to prevent deformation during valve operation.
[0079] To ensure good sealing performance, the feed valve 15 is equipped with a high-temperature resistant and wear-resistant rubber sealing ring between the valve plate and the valve body. The sealing ring is made of fluororubber, which has excellent high-temperature resistance (withstanding temperatures up to approximately 200℃), chemical corrosion resistance, and good elastic recovery. The shape of the sealing ring fits tightly against the sealing surfaces of the valve plate and valve body. When the valve is closed, it effectively prevents material leakage and hot air flow, ensuring that the feed pipe 4 is completely sealed when feeding is not required.
[0080] The actuator utilizes a high-precision, high-reliability integrated electric actuator equipped with a high-performance motor. The motor employs a planetary gear reduction structure, providing significant torque output and easily driving the valve plate to open and close. It operates stably even when the valve has been inactive for extended periods or under pressure from accumulated material. The actuator features a travel limit switch, precisely controlling the valve plate's opening angle and stroke range, enabling accurate adjustment of the valve to be fully open, fully closed, or at any intermediate opening degree to meet diverse material flow control requirements. Furthermore, it incorporates a torque protection device that automatically cuts off the motor power supply when excessive resistance (such as material blockage) is encountered during valve opening and closing, preventing motor overload damage and protecting the entire valve structure.
[0081] The electric actuator of the discharge valve 15 is connected to the control system. Operators can set parameters such as the opening and closing time and opening degree of the discharge valve 15 through a human-machine interface in the control system, achieving remote automated control. Furthermore, the discharge valve 15 is also linked to other components in the heating assembly 1 for control. For example, based on temperature data from the temperature detection unit in the odor dispersing bin 11 and information such as the number of material cycles and time in the first circulation assembly, the control system automatically issues a command to drive the discharge valve 15 to open to the set opening degree when the material reaches the predetermined heating and deodorization effect, allowing the material to enter the cooling assembly in the next stage through the feed pipe 4. Simultaneously, in case of emergencies (such as device malfunction, over-temperature alarms, etc.), the control system can immediately close the discharge valve 15 to prevent further material transmission, ensuring the safety and stability of the entire device.
[0082] Continue to refer to Figures 1 to 3 In one feasible embodiment, the cooling tank 21 is provided with a plurality of second through holes, and the bottom of the cooling tank 21 is provided with a second opening 25. The cooling assembly also includes a second circulation assembly, which is connected to the second through holes and the second opening 25 respectively, for circulating the TPV material in the cooling tank 21 within the cooling tank 21.
[0083] Each of the second openings 25 has an anti-odor component at its bottom.
[0084] The second loop component includes:
[0085] The second circulating air duct 23 has multiple interfaces at one end, the number of which is the same as the number of the second through holes, and the multiple interfaces are connected to the multiple second through holes one by one.
[0086] The other end of the second circulating air duct 23 is connected to the second opening 25. The TPV material in the cooling barrel 21 falls from the second opening 25 along the second circulating air duct 23 into the odor dissipation barrel 11 through the second through hole.
[0087] The second feeding fan 24 is located at the top of the cooling tank 21 and is connected to the second circulating air duct 23. The second feeding fan 24 evacuates the second circulating air duct 23 to create a negative pressure in the second circulating air duct 23, which is used to draw TPV material into the second circulating air duct 23.
[0088] In this implementation, the cooling tank 21 is cylindrical in shape and adopts a double-layer structure design. The outer layer is made of carbon steel with a thickness of 6-10 mm, providing support and protection. The inner layer is made of food-grade 304 stainless steel with a thickness of approximately 3-5 mm, directly contacting the TPV material to ensure that the material is not contaminated and is easy to clean and maintain. The ratio of the tank's height to its diameter is rationally determined based on factors such as the required residence time for material cooling and available space. For example, the height can be approximately 1.5-2 times the diameter to provide sufficient space for the material to cool fully. The top is domed, facilitating the rational distribution of material and airflow. Multiple second through holes and reserved holes for installing related components are provided at different locations on the dome. The reserved holes are equipped with sealing caps for convenient daily inspection and maintenance. The bottom is inverted conical, with a second opening 25 at the center of the cone. The diameter of the second opening 25 is determined based on the material flow rate and ease of discharge, generally between 8-12 cm. Its edges are rounded, and the inner wall is smooth to facilitate smooth material discharge.
[0089] The cooling tank 21 has a double-layered structure with a cooling chamber in the middle, which is connected to the external cooling circulation system 22 via pipes. The cooling circulation system 22 consists of a refrigeration unit, a circulation pump, a coolant storage tank, and a temperature control device. The refrigeration unit uses a compressor refrigeration principle, and the appropriate refrigeration power can be selected according to actual needs. For example, for TPV materials with a processing capacity of about 500 kg per hour, the refrigeration power of the refrigeration unit can be set between 10-20 kW to provide a stable low-temperature coolant (such as an ethylene glycol aqueous solution, with a temperature adjustable to 5℃-15℃). The circulation pump delivers the coolant from the storage tank to the cooling chamber of the cooling tank 21, allowing it to circulate within the chamber and carry away the heat dissipated by the material, thus achieving a cooling effect. The temperature control device monitors the coolant temperature in real time and automatically adjusts the operating power of the refrigeration unit according to the set value to ensure that the coolant temperature remains stable within a suitable range and to ensure consistent cooling effect.
[0090] Multiple second through holes are evenly distributed at different positions on the dome of the cooling tank 21. Their diameter is determined based on factors such as the material circulation flow rate and the duct interface size of the second circulation component, and is typically between 10-15 cm. The edges of the second through holes are finely polished, with a roughness Ra value of less than 0.8 μm. Reinforcing ribs made of stainless steel are also installed around the holes, with a thickness of 3-5 mm and a width of approximately 2-3 cm, to enhance the strength of the tank body in this area and prevent deformation of the perforated structure due to frequent material circulation, which could affect the sealing and stability of the device.
[0091] The second circulating duct 23 is made of high-temperature resistant, wear-resistant, and smooth-walled polytetrafluoroethylene (PTFE) tubing, which has good chemical stability and a low coefficient of friction, effectively reducing material adhesion and blockage during transport. The duct's inner diameter is designed according to material flow rate and velocity requirements, generally between 15-25 cm, with a wall thickness of 3-5 mm, ensuring pipe strength and sealing. Multiple interfaces at one end of the duct correspond one-to-one with the multiple second through holes in the dome of the cooling tank 21. The interfaces use flange connections, with high-temperature and low-temperature resistant rubber gaskets, such as silicone rubber gaskets, installed between the flanges to ensure a tight seal and prevent material leakage and the ingress of outside air. A flexible transition section, made of corrugated metal flexible tubing, 10-20 cm in length, is also provided at each connection point between the duct and the interface. This effectively buffers the impact of material entering the duct, preventing loosening or damage caused by rigid connections. The other end of the duct is connected to the second opening 25 at the bottom of the cooling tank 21. The connection is also made of a well-sealed flange and reinforced with a structure to ensure a firm and reliable connection, so that the material can fall smoothly from the second opening 25 along the second circulating duct 23 and then through the second through hole back into the cooling tank 21, thus achieving circulation.
[0092] The second feeding blower 24 is installed on top of the cooling tank 21 and connected to the second circulating air duct 23. A Roots blower is selected as the power source, featuring stable flow rate, wide pressure range, and strong adaptability to materials, making it suitable for suction and circulating material transport. Based on the length and diameter of the second circulating air duct 23 and the material conveying resistance, a suitable Roots blower model is selected. For example, for circulating air ducts of the above dimensions and conventional TPV material conveying, a Roots blower with an air volume of 500-1000 cubic meters per hour and an air pressure of 3000-5000 Pascals can be selected. Silencers are installed at the inlet and outlet of the second feeding blower 24 to reduce noise during operation, and vibration damping pads are also provided to reduce the impact of blower vibration on the entire device. The second feeding fan 24 creates a negative pressure environment in the second circulating air duct 23 by drawing a vacuum, thereby drawing the TPV material in the cooling tank 21 into the air duct and circulating it along the air duct, improving the cooling uniformity of the material in the cooling tank 21 and further enhancing the cooling effect.
[0093] Each second opening 25 is equipped with an anti-backflow element at its bottom. This anti-backflow element employs a check valve structure, with the valve body made of 304 stainless steel, possessing excellent corrosion resistance and mechanical strength. The check valve core is spherical or conical, also made of stainless steel, with a smooth surface treatment to ensure flexible operation and prevent material jamming during opening and closing. The valve core is tightly fitted to the valve seat by spring or gravity. When material flows normally from the cooling tank 21 through the second opening 25, the valve core opens under the weight or pressure of the material, ensuring smooth passage. Conversely, when negative pressure or a backflow of odor occurs in the cooling tank 21, the valve core quickly closes under the spring force (or its own weight) and reverse pressure, effectively preventing odors and hot air from entering the cooling tank 21, thus avoiding impact on the cooling effect and quality of the material. The check valve is installed using a flange or threaded connection, tightly fixed to the bottom of the second opening 25. A sealing gasket is installed at the connection to ensure a good seal and prevent leakage points that could lead to backflow.
[0094] The entire device is equipped with a centralized control system, which can uniformly operate and monitor the second circulation component (including the second feeding fan 24, related valves, etc.) and all components of the cooling circulation system 22. Operators can set parameters such as cooling temperature, material circulation frequency, and circulation time through a human-machine interface (e.g., a touchscreen). The control system automatically coordinates the operation of each part according to the set program, ensuring that the material is circulated and cooled in the cooling tank 21 in a predetermined manner. Simultaneously, it displays real-time operating data such as temperature and material flow rate at key locations within the cooling tank 21. In case of abnormalities (such as abnormal cooling temperature, fan failure, valve leakage, etc.), the system will promptly issue an alarm, facilitating quick troubleshooting and problem-solving by operators. This ensures the device safely and efficiently completes the deodorization and cooling of TPV materials, ultimately obtaining high-quality TPV materials.
[0095] In one feasible embodiment, the anti-odor component includes: an umbrella-shaped component, on which TPV material falls from the feed inlet; and a dispersing component, which has the same shape as the umbrella-shaped component but is larger in size. The dispersing component is located below the umbrella-shaped component and is rotatably connected to it. The TPV material falls from the umbrella-shaped component onto the dispersing component, and the rotating dispersing component spreads the TPV material into the cooling tank 21.
[0096] In this embodiment, the umbrella-shaped component has an overall inverted conical structure, with its apex angle generally between 120° and 150°. This angle design facilitates the smooth sliding of material from the inlet onto the dispersing component below. The umbrella-shaped component is made of high-temperature resistant, corrosion-resistant engineering plastics (such as polyetheretherketone, PEEK) or 304 stainless steel. If engineering plastic is used, its thickness is generally between 5 and 8 mm; if stainless steel is used, the thickness is approximately 3 to 5 mm, ensuring it can withstand the impact of the material and operate stably in the high-temperature environment inside the cooling tank 21. The top of the umbrella-shaped component is fixed to a support crossbar inside the cooling tank 21 by welding or bolting. The support crossbar is made of stainless steel and spans a suitable position below the inlet of the cooling tank 21, ensuring the umbrella-shaped component is firmly installed and in a stable horizontal state.
[0097] The surface of the umbrella-shaped component is frosted, with a roughness Ra value controlled between 1.6 and 3.2 μm. This moderate roughness increases the friction between the material and the surface, allowing it to slide along the edge, while preventing the material from accumulating in one place due to excessive smoothness. Simultaneously, a downward-sloping guide channel is designed around the edge of the umbrella-shaped component. The channel is 2-3 cm wide and 1-1.5 cm deep, guiding the material to be more evenly dispersed onto the lower distribution component, preventing material accumulation in localized areas that could affect subsequent cooling performance.
[0098] The dispersing component also has an inverted conical structure, similar in shape to the umbrella-shaped component, but larger in size. Its diameter is generally 20%-30% larger than the umbrella-shaped component to ensure it can catch all material sliding down and provide sufficient space for dispersion. The dispersing component is made of the same high-temperature and corrosion-resistant material as the umbrella-shaped component (such as polyetheretherketone (PEEK) or stainless steel 304), and its overall thickness can be slightly thicker, between 6-10 mm, to enhance its structural strength. The dispersing component and the umbrella-shaped component are rotatably connected via a central shaft. The central shaft is made of high-strength stainless steel with a diameter between 3-5 cm. Its top is connected to the bottom of the umbrella-shaped component via a bearing. The bearing is a high-temperature and wear-resistant deep groove ball bearing to ensure flexible rotation and withstand certain axial and radial loads. The bottom of the central shaft passes through a pre-drilled mounting hole at the bottom of the cooling tank 21 (the mounting hole is sealed) and connects to an external drive device to ensure stable rotation of the dispersing component.
[0099] The dispersing component is driven by a geared motor, which is installed on the outer bottom of the cooling tank 21. Its output shaft is connected to the central shaft via a coupling. The power of the geared motor is determined based on factors such as the size of the dispersing component, the weight of the material, and the required rotation speed, generally between 0.5 and 2 kilowatts. The motor speed is appropriately reduced by a reducer, keeping the speed of the dispersing component at approximately 5-15 revolutions per minute. This speed ensures that the material is evenly dispersed in all directions under centrifugal force without causing material splashing or dust generation due to excessive speed. As the material slides from the umbrella-shaped component onto the dispersing component, it is evenly scattered into different positions within the cooling tank 21 under the combined action of centrifugal force and gravity, achieving uniform material dispersion, which helps improve cooling efficiency, and also effectively prevents material accumulation in certain areas, thus preventing uneven cooling. Moreover, during the rotation of the dispersing component, a certain gap is maintained between its bottom and the bottom of the cooling tank 21, with a gap height of about 3-5 cm, to avoid direct contact with the bottom of the tank and cause friction and wear, while also facilitating the smooth passage of materials and their distribution throughout the tank.
