Description

Technical Field

[0001] This invention relates to a deodorization device and application process for PHA products, belonging to the field of auxiliary equipment for polymer material processing. Background Technology

[0002] PHA (polyhydroxyalkanoate), as a biodegradable polymer material, releases odorous gases containing VOCs during synthesis, processing, and storage due to the decomposition of ester bonds or the volatilization of residual monomers. Dedicated deodorization equipment is key to meeting environmental protection and production requirements. Existing PHA deodorization equipment is mostly based on "adsorption deodorization + hot airflow assistance". It uses activated carbon to adsorb odor molecules and uses hot airflow to accelerate the volatilization of odors on the PHA surface. However, it has obvious shortcomings in heat and airflow management.

[0003] In existing PHA deodorization equipment, the material chamber is mostly a fixed volume structure, which cannot flexibly adjust the size of the chamber according to the actual number of PHA products processed. When only a small number of products are processed (such as only one basket of products), an overly large fixed chamber will cause the hot airflow to be dispersed, requiring more energy to reach the target temperature. The heating speed is slow and the energy consumption is high. When processing multiple baskets of products and discharging them in sequence, the fixed chamber cannot focus the airflow and heat on the product distribution area. This not only easily leads to uneven local heating, but also reduces the overall deodorization efficiency and energy utilization rate because the chamber space is not adapted to the needs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a PHA product deodorization device and application process to solve the problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a PHA product deodorization device and application process, the structure of which includes: a shell, wherein a main chamber is provided inside the shell;

[0006] A partition is provided horizontally in the main chamber, which divides the main chamber into a material chamber at the bottom and an airflow chamber at the top. A slide rail extending along its length is fixed on the upper surface of the partition, and a vertically arranged slide rail type drive blade is slidably mounted on the slide rail. The slide rail type drive blade can move horizontally left and right along the slide rail.

[0007] The partition plate has several flow-guiding and heat-insulating blades installed axially at intervals along its length. The sliding rail type drive blade plate is adapted to the flow-guiding and heat-insulating blades. When the sliding rail type drive blade plate moves along the sliding rail to the target position, it can drive the three flow-guiding and heat-insulating blades on its right side to open.

[0008] Preferably, the slide rail type drive blade includes a small arc-shaped guide plate, a heat insulation plate, and a slide seat connector. The small arc-shaped guide plate and the heat insulation plate are distributed vertically and vertically, with the small arc-shaped guide plate located directly above the heat insulation plate. The small arc-shaped guide plate and the heat insulation plate are fastened together by the slide seat connector.

[0009] The sliding block connector slides in conjunction with the slide rail. The small arc-shaped guide plate is located in the airflow control zone. The arc-shaped surface of the small arc-shaped guide plate faces the opening side of the guide heat insulation blade. The heat insulation plate is located in the material receiving zone.

[0010] Preferably, the heat-insulating blades are rectangular in shape, and a plurality of the heat-insulating blades are arranged in a linear direction in the middle of the partition, with adjacent heat-insulating blades being arranged in a seamless fit.

[0011] Each of the heat-insulating and flow-guiding blades has an integrally formed center block on its left side. The weight of the center block is greater than the weight of the heat-insulating and flow-guiding blade itself. When there is no external force, the heat-insulating and flow-guiding blades rely on the gravity of the center block on its left side to rotate around the axis and return to the horizontal closed state, keeping the adjacent blades in close contact without gaps.

[0012] The center of each side of the flow-guiding heat insulation blade is integrally formed with a flipping protrusion, which is located directly above the axial connection position of the flow-guiding heat insulation blade.

[0013] Preferably, a pressure strip is integrally formed on the right side of the slide block connector. The length of the pressure strip is adapted to the flipping protrusions that act simultaneously on the three flow-guiding heat insulation blades. The head of the pressure strip has an arc-shaped structure.

[0014] The partition plate is provided with a limiting groove that matches the flipping protrusion of the heat-insulating blade. When the pressure strip moves to the right with the sliding block connector, the head of the pressure strip can press down on the flipping protrusion of the heat-insulating blade to make the heat-insulating blade rotate around the axis. At the same time, the flipping protrusion is embedded in the corresponding limiting groove. The structure of the limiting groove limits the maximum rotation angle of the heat-insulating blade to 85°, which is the appropriate angle for the heat-insulating blade in the ventilation state.

[0015] The head of the slide rail is provided with a limiting protrusion, which is adapted to the slide block connector;

[0016] A rubber sealing strip is provided between the guide rail of the partition and the material cavity. The rubber sealing strip is fastened to the inner wall of the material cavity and is distributed in a left-right mirror pattern. The rubber sealing strip is elastically set and only when the sliding block connector slides to the corresponding position will the sliding block connector squeeze the rubber sealing strip to deform it.

[0017] Preferably, a deodorizing and purifying chamber is provided on the right side of the main chamber, the deodorizing and purifying chamber is connected to the main chamber, and a dustproof layer is fastened between the deodorizing and purifying chamber and the main chamber.

[0018] The deodorizing and purifying chamber is securely fitted with a grid base. The grid base has breathable grids on both the left and right sides. The grid base has a three-layer structure. Each of the three layers of the grid base has a removable activated carbon storage box. The activated carbon storage box has a permeable structure on both the left and right sides.

[0019] Preferably, an air inlet is provided on the right side of the housing, and an evaporator module is installed inside the air inlet. The evaporator module includes a refrigeration shell, an evaporator assembly, a guide fan, an arc-shaped return air guide plate, and an L-shaped ventilation grille. The arc-shaped return air guide plate is provided inside the evaporator module.

[0020] An evaporator assembly is fastened between the refrigeration housing and the arc-shaped return air guide plate. An L-shaped vent grille is fastened to the front of the refrigeration housing. The L-shaped vent grille is divided into a short-side return air grille and a long-side air intake grille. The air intake grille is located to the right of the evaporator assembly.

[0021] Two air guide fans are mounted directly above the refrigeration housing. These fans guide and transport the airflow upwards only within the area enclosed by the evaporator assembly, the housing, and the arc-shaped return air guide plate.

[0022] Preferably, a large arc-shaped baffle is fastened to the top of the evaporator module, with the arc-shaped opening of the large arc-shaped baffle facing to the left.

[0023] A condenser module is fastened to the left of the large arc-shaped guide plate and directly above the partition. The condenser module includes a condenser frame, a condenser assembly, and a first guide fan assembly. The condenser frame has a left-right through structure. The right part of the condenser frame is adapted to the left guide end of the large arc-shaped guide plate to receive the airflow guided by the large arc-shaped guide plate.

[0024] The condenser assembly is installed at an angle inside the condenser frame. There are two condenser assemblies arranged side by side. The first guide fan assembly is fastened to the left side of the condenser frame. The condenser module is located to the right side of the airflow chamber.

[0025] A compressor is mounted on the right side of the evaporator module. The compressor is connected to the evaporator assembly in the evaporator module and the condenser assembly in the condenser module through pipes to form a sealed connection.

[0026] Preferably, a second guide fan assembly is installed between the grille base and the evaporator module, and the second guide fan assembly is inclined to the lower left.

[0027] A third guide fan assembly is fastened to the right of the grid base and in front of the evaporator module. The material chamber and the deodorization and purification chamber are connected from left to right. The airflow after deodorization in the material chamber flows to the right, passes through the dustproof layer, the grid base and the activated carbon placement box in sequence, and is discharged from the right of the third guide fan assembly with the cooperation of the second and third guide fan assemblies.

[0028] An airflow guide plate is fastened to the right side of the third guide fan assembly. The airflow guide plate is isolated and has the return air grille section corresponding to the L-shaped ventilation grille directly behind it. The airflow discharged by the third guide fan assembly is guided by the airflow guide plate and then flows through the return air grille to the space between the air intake grille and the evaporator assembly.

[0029] Preferably, a guide groove is provided at the rear of the material cavity, and a transmission assembly is movably assembled inside the guide groove. The transmission assembly includes a ball screw, a screw nut block, a support limit post, a support block, and a drive motor.

[0030] Two support blocks are arranged radially in the guide groove. A ball screw is axially mounted between the two support blocks along the guide groove. Support limit posts are arranged radially above and below the ball screw. The screw nut block is slidably assembled on the ball screw and the two support limit posts.

[0031] A drive motor is fastened to the left side of the support block. The drive motor is connected to a ball screw drive. The ball screw nut block is fastened to the left side of the insulation plate by bolts.

[0032] The openings of the main chamber and the deodorizing and purifying chamber are both positioned facing the front of the device, and both the main chamber and the deodorizing and purifying chamber are in communication with the outside of the device. Sealing door panels are installed and connected to the corresponding positions of the openings of the main chamber and the deodorizing and purifying chamber along the opening axis.

[0033] Preferably, based on the actual batch size of PHA products, the insulation plate and the connected sliding-rail drive vane plate are adjusted to the appropriate position via the transmission assembly behind the material chamber, and the main chamber sealing door is closed. If activated carbon needs to be replaced, the deodorizing and purification chamber sealing door is opened, the internal activated carbon storage box is pulled out and replaced, and then the door is closed to ensure the sealing of both chambers. The device is started, and the airflow introduced by the evaporator module is treated and guided to the condenser module for secondary temperature control via a large arc-shaped guide plate, and then sent into the airflow chamber via the first guide fan group. At the same time, the sliding-rail drive vane plate opens its right-side guide and heat insulation blades by pressing the flipping protrusion with the pressure strip. The temperature is raised to 85°C, allowing hot air to flow into the material chamber to accelerate the volatilization of odors from the product. After the odor-laden airflow is filtered by the dustproof layer and purified by activated carbon adsorption in the deodorizing purification chamber, the purified airflow is returned to the evaporator module through the airflow guide plate to form a closed loop. During operation, the position of the insulation plate is finely adjusted by the drive motor according to the odor concentration of the product to optimize the heating efficiency. The rubber sealing strip is squeezed by the sliding seat connector to ensure the sealing of the material chamber. After the device finishes running, the sliding wheel drive plate is reset by the drive motor, and the guide heat insulation blades automatically close under the action of the center of gravity block, opening the main chamber sealing door and taking out the PHA product.

[0034] The present invention provides a PHA product deodorization device and application process, which has the following effects:

[0035] 1. The equipment drives the insulation plate to move along the slide rail through the transmission component. The volume of the material chamber can be flexibly adjusted according to the actual batch size of PHA products (single basket to multiple baskets), avoiding the problem of heat dissipation caused by a fixed chamber. With the dynamic sealing design of the elastic rubber sealing strip, heat can be focused on the target area, increasing the heating rate of the material chamber by 30%-50%, while reducing heat loss through gaps and reducing overall energy consumption. It is suitable for the deodorization needs of PHA products with different production volumes, and takes into account the flexibility of small batch processing and the high efficiency of large batch processing.

[0036] 2. Closed-loop airflow circulation system: It realizes the whole process of airflow temperature control, deodorization, purification and reuse. The combination design of three-layer activated carbon placement box and dustproof layer can deeply adsorb the odor airflow containing VOCs. The inclined installation of condenser components and the directional airflow of large arc-shaped guide plate ensure that the temperature-controlled airflow evenly covers the material cavity and avoids uneven deodorization caused by local temperature deviation.

[0037] 3. Efficient airflow distribution is achieved through the linkage structure of the sliding-rail type drive blade and the guide heat insulation blade: When the drive motor drives the sliding-rail type drive blade to move horizontally along the slide rail, the drive blade will only open the three guide heat insulation blades on its right side after reaching the preset target position through the pressure strip. This can match the actual number and distribution position of PHA products in the material cavity. At the same time, the unopened guide heat insulation blades remain closed to maintain the sealing and heat insulation of other areas of the airflow cavity, further reducing heat loss.

[0065] Please see Figures 1 to 12 This invention provides a PHA product deodorization device and its application process. The device includes a housing 1 with a main chamber 12 inside. A partition 2 is horizontally arranged within the main chamber 12, dividing it into a lower material chamber 12a and an upper airflow chamber 12b. A slide rail 21 extending along the length of the partition 2 is fixedly mounted on its upper surface. A vertically mounted slide rail-type drive plate 3 is slidably mounted on the slide rail 21, allowing it to move horizontally left and right along the slide rail 21. The lower material chamber 12a is used to place the PHA product to be deodorized, providing a stable processing environment and preventing direct airflow impact that could damage the product. The upper airflow chamber 12b serves as a flow channel for hot and deodorizing airflow, ensuring that the airflow circulates along a preset path. The slide rail 21 extending along the length of the partition 2 provides a stable horizontal guide for the slide rail-type drive plate 3, ensuring the straightness and stability of the drive plate during movement.

[0066] A number of flow-guiding and heat-insulating blades 4 are axially spaced along the length of the middle part of the partition 2. The sliding drive plate 3 and the flow-guiding and heat-insulating blades 4 are driven and adapted. When the sliding drive plate 3 moves along the slide rail 21 to the target position, it can drive the three flow-guiding and heat-insulating blades 4 on its right side to open. The number of flow-guiding and heat-insulating blades 4 axially spaced along the length of the middle part of the partition 2 is a key component for realizing the control of the airflow path and heat isolation inside the airflow cavity 12b. Its initial state is closed, which can effectively block the airflow and heat transfer in different areas inside the airflow cavity 12b. The sliding drive plate 3 and the flow-guiding and heat-insulating blades 4 are driven and adapted.

[0067] Following the principle of positioning and on-demand opening: When the sliding drive plate 3 moves horizontally left and right along the sliding rail 21 under the action of the drive motor 95, the sliding drive plate 3 forms a linkage with the guide heat insulation blade 4 through the pressure strip 331. Only when the drive plate moves to the preset target position will it drive the three guide heat insulation blades 4 on its right side to open. This design can flexibly adjust the airflow area of ​​the airflow cavity 12b according to the actual number and distribution of PHA products in the material cavity 12a. For example, when only a small number of products are placed on the right side of the material cavity 12a, the drive plate moves to the corresponding position and opens the three guide heat insulation blades 4 on the right side, so that the hot airflow and deodorizing airflow are concentrated to the right area, reducing airflow waste and improving local deodorization efficiency and heat utilization. At the same time, the unopened guide heat insulation blades 4 remain closed to maintain the sealing and heat insulation of other areas of the airflow cavity 12b.

[0068] The sliding rail type guide vane 3 includes a small arc-shaped guide vane 31, a heat insulation plate 32, and a sliding seat connector 33. The small arc-shaped guide vane 31 and the heat insulation plate 32 are distributed vertically and correspondingly, with the small arc-shaped guide vane 31 located directly above the heat insulation plate 32. The small arc-shaped guide vane 31 and the heat insulation plate 32 are fastened together by the sliding seat connector 33. The sliding seat connector 33 is slidably engaged with the slide rail 21. The small arc-shaped guide vane 31 is located within the airflow control zone, with its arc-shaped surface facing the opening side of the guide vane 4. The heat insulation plate... 32 corresponds to the material receiving area; the sliding vane plate 3 is a combined structure consisting of a small arc-shaped guide plate 31, a heat insulation plate 32, and a sliding seat connector 33. The small arc-shaped guide plate 31 and the heat insulation plate 32 are distributed vertically and vertically, with the small arc-shaped guide plate 31 located directly above the heat insulation plate 32. This design can match the partitioned structure of the airflow chamber 12b above the main chamber 12 and the material chamber 12a below. The small arc-shaped guide plate 31 is located in the airflow chamber 12b, with its arc-shaped surface facing the opening side of the guide and heat insulation blade 4. The structure utilizes fluid dynamics principles to smoothly guide the flowing hot air and deodorizing air after the guide and heat insulation blades 4 are opened, preventing eddies or air loss at the blade opening point. This ensures that the airflow can efficiently flow to the target area along the preset direction, improving airflow utilization efficiency. The heat insulation plate 32, located in the material cavity 12a, can block the transfer of heat from the hot air in the airflow cavity 12b to the non-target area of ​​the material cavity 12a through its own heat insulation performance, preventing heat loss and maintaining the stability of the internal temperature environment of the material cavity 12a. The sliding block connector 33 ensures a stable overall structure through a tight connection, preventing loosening of components due to airflow impact or movement. Furthermore, its sliding fit design with the slide rail 21 provides guiding support for the entire slide rail type guide vane plate 3 to move horizontally along the slide rail 21, ensuring that the relative position of the upper and lower components remains stable during the movement of the guide vane plate. This ensures that the guiding effect of the small arc-shaped guide vane plate 31 on the airflow and the heat insulation effect of the heat insulation plate 32 on the material cavity 12a are not affected by movement.

[0069] The flow-guiding and heat-insulating blades 4 have a rectangular structure. Several flow-guiding and heat-insulating blades 4 are arranged in a linear direction in the middle of the partition plate 2, and adjacent flow-guiding and heat-insulating blades 4 are arranged in a seamless fit. As a preferred flow-guiding and heat-insulating blade, the design of adopting a rectangular structure and arranging in a linear direction in the middle of the partition plate 2, with adjacent blades arranged in a seamless fit, is based on the principle of improving the barrier sealing and airflow control accuracy between the airflow cavity 12b and the material cavity 12a. The rectangular structure can be adapted to the horizontal extension direction of the partition plate 2 and the spatial dimensions of the main chamber 12, ensuring that the blades can completely cover the airflow channels of the corresponding area on the partition plate 2 when they are rotated open or closed. The linear arrangement makes the blades form a continuous barrier band. With the seamless fit of adjacent blades, the airflow and heat transfer in different areas inside the airflow cavity 12b can be blocked when the blades are closed.

[0070] Each of the heat-insulating and flow-guiding blades 4 has an integrally formed center weight block 41 on its left side. The weight of the center weight block 41 is greater than the weight of the heat-insulating and flow-guiding blade 4 itself. When there is no external force, the heat-insulating and flow-guiding blade 4 rotates around its axis to return to a horizontal closed state by the gravity of its center weight block 41, keeping adjacent blades in close contact without gaps. Each of the left and right sides of the heat-insulating and flow-guiding blade 4 has an integrally formed flipping protrusion 42 at its center position. The flipping protrusion 42 is located directly above the axial connection position of the heat-insulating and flow-guiding blade 4. The design of the integrally formed center weight block 41 on the left side of the heat-insulating and flow-guiding blade 4, with a weight greater than the weight of the blade itself, follows the principle of gravity self-reset. When the sliding guide blade plate 3 is removed, the blade can... The blade automatically rotates and resets around the axis under the gravity of the center block 41, eventually returning to a horizontal closed state. The gravity of the center block 41 further enhances the gapless fit between adjacent blades, preventing airflow leakage due to insufficient blade weight. The integrated flipping protrusion 42 on the center of the left and right sides of the blade is located directly above the axial connection position of the blade and is the core structure for the transmission adaptation between the blade and the slide rail drive plate 3. The position design of the flipping protrusion 42 ensures that when the slide rail drive plate 3 moves to the corresponding position, its drive end can accurately contact the protrusion, converting the horizontal thrust into the torque for the blade to rotate around the axis, thus opening the blade.

[0071] A pressure strip 331 is integrally formed on the right side of the slide connector 33. The length of the pressure strip 331 is adapted to act simultaneously on the flipping protrusions 42 of the three guide heat insulation blades 4. The head of the pressure strip 331 has an arc-shaped structure. The partition plate 2 has a limiting groove 22 that matches the flipping protrusions 42 of the guide heat insulation blades 4. When the pressure strip 331 moves to the right with the slide connector 33, the head of the pressure strip 331 can press down on the flipping protrusions 42 of the guide heat insulation blades 4, causing the guide heat insulation blades 4 to rotate around the axial direction. At the same time, the flipping protrusions 42 are embedded in the corresponding limiting groove 22. The structure of the limiting groove 22 limits the maximum rotation angle of the guide heat insulation blades 4 to 85°, which is the appropriate angle for the guide heat insulation blades 4 in the ventilation state. The length of the slide connector 33 is adapted to act simultaneously on the flipping protrusions 42 of the three guide heat insulation blades 4. The size ensures that the target blade is driven during the movement of the blade drive plate. The arc-shaped structure of the pressure strip 331 head utilizes the principle of curved surface contact. When the flipping protrusion 42 is pressed to the right, the horizontal thrust is smoothly converted into the torque of the blade rotating around the axis, reducing the friction loss between the protrusion and the pressure strip 331, and avoiding component damage caused by rigid contact. The limiting groove 22 opened on the partition plate 2 matches the flipping protrusion 42. When the pressure strip 331 drives the blade to rotate, the flipping protrusion 42 is embedded in the limiting groove 22. The groove structure limits the maximum rotation angle of the blade to 85°. This angle design is optimized to meet the ventilation requirements, which can ensure that the airflow passes through the blade gap in an efficient path, and can avoid the center of gravity shift caused by excessive blade flipping. It ensures that the blade can be smoothly reset under the action of the center of gravity block 41 after the external force is removed.

[0072] The head of the slide rail 21 is provided with a limiting protrusion 211, which is adapted to the slide block connector 33; a rubber sealing strip 73 is provided between the guide rail of the partition 2 and the material cavity 12a. The rubber sealing strip 73 is fastened to the inner wall of the material cavity 12a and distributed in a mirror image. The rubber sealing strip 73 is elastically set. Only when the slide block connector 33 slides to the corresponding position, the slide block connector 33 squeezes the rubber sealing strip 73 to deform it. The limiting protrusion 211 at the head of the slide rail 21 is adapted to the slide block connector 33. Its function is to limit the maximum travel of the slide block connector 33 by mechanical limiting, so as to prevent the drive blade from falling off or colliding with other parts due to excessive movement beyond the range of the slide rail 21. The rubber sealing strip 73 installed between the material chambers 12a adopts an elastic structure that is tightly installed on the inner wall of the material chamber 12a and distributed in a mirror image on the left and right. Its working principle is as follows: Under normal conditions, the sealing strip remains in a natural state, blocking the gap between the guide rail and the slide, without affecting the movement of the slide connector 33. When the slide connector 33 slides to the corresponding position, its side squeezes the sealing strip to deform it. Through the elastic restoring force of the sealing strip, it tightly adheres to the surface of the slide connector 33, preventing the heat in the airflow chamber 12b from being lost through the gap. This ensures that the hot air can only flow directionally to the corresponding area of ​​the material chamber 12a through the three blade gaps formed when the guide heat insulation blade 4 is opened, thereby ensuring that the hot airflow flows along the preset path and forms a complete hot airflow circulation loop.

[0073] A deodorizing and purifying chamber 13 is located on the right side of the main chamber 12, and is connected to the main chamber 12. A dustproof layer 7a is securely installed between the deodorizing and purifying chamber 13 and the main chamber 12. A grid base 5 is securely installed inside the deodorizing and purifying chamber 13. Both sides of the grid base 5 have breathable grids 51. The grid base 5 has a three-layer structure, and each of the three layers contains a removable activated carbon storage box 52. The activated carbon storage box 52 has a permeable structure on both sides. The deodorizing and purifying chamber 13, located on the right side of the main chamber 12 and connected to it, allows the airflow (containing VOCs, a small amount of dust, etc.) after odors have been volatilized in the material chamber 12 through the material chamber 12a to flow naturally to the deodorizing and purifying chamber 13, forming an airflow path of odor generation and directional purification, preventing odors from lingering in the device. The two are securely connected. The installed dustproof layer 7a serves as a pre-filter barrier for the airflow entering the deodorizing and purification chamber 13. It can intercept solid impurities such as PHA dust and material debris carried in the airflow, preventing impurities from entering the subsequent purification structure and clogging the ventilation channels or contaminating the activated carbon. This ensures the long-term stable operation of the internal components of the deodorizing and purification chamber 13. The grid base 5 adopts a three-layer structure, with each layer having a removable activated carbon placement box 52. This layered design increases the total amount of activated carbon and the contact area with the airflow, extending the residence time of the airflow in the purification chamber. This allows odor molecules to come into more full contact with the pores of the activated carbon, deeply removing odors through physical adsorption and improving the purification effect. On the other hand, the removable design facilitates the replacement and maintenance of the activated carbon in the later stages. The activated carbon can be replaced without disassembling the grid base 5, reducing the maintenance cost and operation difficulty of the device.

[0074] An air inlet 14 is provided on the right side of the housing 1. An evaporator module 6 is installed inside the air inlet 14. The evaporator module 6 includes a cooling housing 61, an evaporator assembly 62, a guide fan 63, an arc-shaped return air guide plate 66, and an L-shaped ventilation grille 64. The arc-shaped return air guide plate 66 is provided inside the evaporator module 6.

[0075] An evaporator assembly 62 is securely mounted between the refrigeration housing 61 and the arc-shaped return air guide plate 66. An L-shaped ventilation grille 64 is securely mounted on the front of the refrigeration housing 61. The L-shaped ventilation grille 64 consists of a short-side return air grille 641 and a long-side intake air grille 642, with the intake air grille 642 located directly to the right of the evaporator assembly 62. Two guide fans 63 are mounted on the top of the refrigeration housing 61. The guide fans 63 only guide and deliver the airflow upward within the area enclosed by the evaporator assembly 62, the housing, and the arc-shaped return air guide plate 66. The air inlet 14 on the right side of the housing 1 provides a mounting carrier for the evaporator module 6, allowing the module to be directly connected to the airflow circulation path of the device, ensuring that external airflow or the device's return airflow can be directed into the module for temperature regulation. The refrigeration housing 61, in conjunction with the arc-shaped return air guide plate 66, forms a relatively sealed heat exchange area, preventing airflow loss during heat exchange and ensuring that the airflow can fully contact the evaporator assembly 62 for temperature exchange. The L-shaped ventilation grille 64, which is fastened to the front of the cooling shell 61, is divided by a short-side return air grille 641 and a long-side intake air grille 642 to match the airflow requirements of the module. The long-side intake air grille 642 is located to the right of the evaporator assembly 62 and can guide the external airflow or return airflow to smoothly enter the heat exchange area where the evaporator assembly 62 is located along the long side. The short-side return air grille 641 provides a return channel for the airflow after heat exchange, ensuring that the airflow returns to the inside of the device to participate in the circulation according to the preset path. The two guide fans 63 mounted on the top of the cooling shell 61 adopt the design of "only guiding and transporting the airflow upward within the area enclosed by the evaporator assembly 62, the shell, and the arc-shaped return air guide plate 66". This is to only transport the airflow that has absorbed heat and cooled by the evaporator assembly 62 upward to the subsequent main chamber 12 of the device, avoiding the direct blowing of external or return airflow that has not undergone heat exchange into the inside of the device, thereby ensuring that the airflow entering the device for circulation is temperature-controlled airflow that meets the temperature requirements.

[0076] A large arc-shaped baffle 7b is fastened to the top of the evaporator module 6, with its arc-shaped opening facing to the left. A condenser module 8 is fastened to the left of the large arc-shaped baffle 7b and directly above the partition 2. The condenser module 8 includes a condenser frame 81, a condenser assembly 82, and a first guide fan assembly 83. The condenser frame 81 has a through-type structure, and its right side is adapted to the left guide end of the large arc-shaped baffle 7b to receive the large arc-shaped baffle. The airflow is guided by the baffle 7b; through the directional airflow of the large arc-shaped baffle 7b and the structural adaptation with the condenser module 8, the synergy of "temperature-controlled airflow delivery - high-efficiency secondary heat exchange" is achieved: the large arc-shaped baffle 7b, which is fastened to the top of the evaporator module 6, has an arc-shaped opening facing to the left. Utilizing the fluid guiding characteristics of the arc-shaped surface, the temperature-controlled airflow delivered upward by the guide fan 63 can be smoothly guided to the left along the inner surface of the arc. Through the air-gathering effect of the arc structure, the airflow is ensured to be stable. The airflow is directed towards the condenser module 8. The condenser module 8, located directly to the left of the large arc-shaped guide plate 7b and above the partition plate 2, has a condenser frame 81 with a through-type structure on both sides. The right side of the frame is adapted to the left guide end of the large arc-shaped guide plate 7b. This structural design allows for seamless connection between the two, ensuring that the airflow guided by the arc-shaped guide plate can fully enter the interior of the condenser frame 81 and prevent airflow leakage. Inside the condenser frame 81, two condenser components 82 are installed at an angle, arranged on the left and right. On the one hand, the angle design increases the contact area between the airflow and the condenser components 82, allowing the airflow to fully exchange heat with the condenser components 82. On the other hand, the two components arranged on the left and right form a layered heat exchange structure, ensuring that the airflow passes through the heat exchange layer by layer, improving the heat exchange uniformity. The first guide fan group 83 on the left side of the condenser frame 81 accelerates the airflow speed inside the condenser frame 81 through active airflow guidance, and at the same time guides the heat-exchanged airflow to the left airflow cavity 12b, providing airflow that meets the temperature requirements for the subsequent PHA deodorization area.

[0077] The condenser assembly 82 is installed at an angle inside the condenser frame 81. There are two condenser assemblies 82, arranged side by side. The first guide fan assembly 83 is fastened to the left side of the condenser frame 81. The condenser module 8 is located to the right of the airflow chamber 12b. The compressor 65 is installed to the right of the evaporator module 6. The compressor 65 is connected to the evaporator assembly 62 in the evaporator module 6 and the condenser assembly 82 in the condenser module 8 through pipes. The compressor 65 installed to the right of the evaporator module 6, with its sealed connection to the evaporator assembly 62 and the condenser assembly 82 through pipes, provides energy support for stable temperature control of the device. As the power core of the refrigeration system, the compressor 65 can compress the refrigeration unit through mechanical compression. Refrigerant is drawn from evaporator assembly 62. At this time, the refrigerant is in a low-pressure gaseous state in evaporator assembly 62, which can absorb heat from the airflow. Then, compressor 65 compresses the low-pressure gaseous refrigerant into a high-pressure gaseous state and delivers it to condenser assembly 82 through pipeline. After entering condenser assembly 82, the high-pressure gaseous refrigerant exchanges heat with the airflow and releases the heat it carries to the airflow, gradually condensing into high-pressure liquid refrigerant, completing the heat exchange cycle. Finally, the high-pressure liquid refrigerant flows back to evaporator assembly 62 through pipeline, and after being throttled and depressurized, it becomes a low-pressure gaseous state again, absorbing heat from the airflow again. This cycle repeats, so that evaporator assembly 62 continuously has the ability to absorb heat and cool down, and condenser assembly 82 continuously has the ability to release heat and exchange heat.

[0078] A second guide fan assembly 71a is installed between the grille base 5 and the evaporator module 6, and the second guide fan assembly 71a is inclined to the lower left. A third guide fan assembly 71b is fastened to the right of the grille base 5 and the front of the evaporator module 6. The material chamber 12a and the deodorizing purification chamber 13 are connected from left to right. The deodorized airflow in the material chamber 12a flows to the right, passing through the dustproof layer 7a, the grille base 5, and the activated carbon placement box 52 in sequence. With the cooperation of the second guide fan assembly 71a and the third guide fan assembly 71b, it is discharged from the right of the third guide fan assembly 71b. This ensures that the deodorized airflow in the material chamber 12a can flow efficiently through the deodorizing purification chamber 13 along a preset path, achieving deep odor filtration. The second guide fan assembly 71a installed between the grille base 5 and the evaporator module 6 is inclined to the lower left. This inclination angle is designed to align with the connection between the material chamber 12a and the deodorizing purification chamber 13. In the passage area, the active airflow generates a suction force to the lower left, accelerating the airflow that has undergone preliminary deodorization in the material chamber 12a and flows to the right into the deodorization and purification chamber 13, while preventing the airflow from stagnating at the connection between the two chambers. The third guide fan group 71b, which is fastened to the right of the grid base 5 and the front of the evaporator module 6, works in synergy with the second guide fan group 71a, with one suction and one push. The second guide fan group 71a draws the airflow into the grid base 5, while the third guide fan group 71b pushes the airflow to the right, driving it to flow fully through the activated carbon placement box 52 in the grid base 5, ensuring the contact time and contact area between the airflow and the activated carbon layer, and improving the odor adsorption efficiency. Furthermore, the material chamber 12a and the deodorization and purification chamber 13 are connected from left to right, providing a basic channel for the airflow to flow from left to right. The airflow passes through the dustproof layer 7a, the grid base 5, and the activated carbon placement box 52 in sequence, completing the purification process from dust removal to deodorization.

[0079] An airflow guide plate 7c is securely mounted to the right of the third guide fan assembly 71b. The airflow guide plate 7c is isolated and its rear corresponds to the return air grille 641 of the L-shaped ventilation grille 64. The airflow from the third guide fan assembly 71b is guided by the airflow guide plate 7c and then flows through the return air grille 641 to the space between the inlet grille 642 and the evaporator assembly 62. The core principle of the airflow guide plate 7c is to create a closed-loop circulation of airflow within the device through isolated guidance and airflow return connection, thereby improving airflow utilization and deodorization efficiency. The isolated design of the airflow guide plate 7c prevents the airflow from the third guide fan assembly 71b from diffusing outside the device or entering non-target areas, ensuring that the airflow flows entirely along the guided path. Simultaneously, the airflow... The air return grille 641 of the L-shaped ventilation grille 64 is located directly behind the air guide plate 7c. This position is designed to connect the return path of the airflow. The purified airflow led out by the third guide fan group 71b changes its flow direction towards the return grille 641 under the obstruction and guidance of the airflow guide plate 7c. Finally, it flows through the return grille 641 to the space between the air inlet grille 642 and the evaporator assembly 62. This process allows the airflow that has completed one round of deodorization and purification to re-enter the temperature control area of ​​the evaporator module 6, contact the evaporator assembly 62 for temperature adjustment, and then participate in the airflow circulation in the device again, forming a closed-loop system of material chamber 12a deodorization → deodorization and purification chamber 13 purification → airflow guide plate 7c return → evaporator module 6 temperature control → recirculation deodorization.

[0080] A guide groove 12a1 is provided directly behind the material chamber 12a. A transmission assembly 9 is movably mounted inside the guide groove 12a1. The transmission assembly 9 includes a ball screw 91, a screw nut block 92, support limiting posts 93, support blocks 94, and a drive motor 95. Two support blocks 94 are arranged radially inside the guide groove 12a1. A ball screw 91 is axially mounted between the two support blocks 94 along the direction of the guide groove 12a1. Support limiting posts 93 are arranged radially above and below the ball screw 91. The screw nut block 92 is slidably mounted on the ball screw 91 and the two support limiting posts 93. Above; a drive motor 95 is fastened to the left side of the support block 94. The drive motor 95 is connected to the ball screw 91. The screw nut block 92 is fastened to the left side of the insulation plate 32 by bolts. The core principle of the transmission component 9 of the material chamber 12a is the controllable movement of the insulation plate 32, thereby adapting to the deodorization requirements of different PHA products. The guide groove 12a1 opened at the rear of the material chamber 12a provides installation and operation space for the transmission component 9, ensuring that the component does not occupy the internal space of the material chamber 12a during operation, and avoiding interference with PHA products. The guide groove 12a1 has a left and right diameter. The two support blocks 94 provide fixed support at both ends of the ball screw 91, ensuring stable rotation of the ball screw 91 along the guide groove 12a1. Furthermore, the positioning function of the support blocks 94 ensures that the ball screw 91 and the upper and lower support limit posts 93 form a regular one-main-two-guide directional structure. When the ball screw 91 rotates under the drive motor 95, the rotational motion is converted into linear motion of the screw nut block 92. The upper and lower support limit posts 93 restrict the rotational freedom of the screw nut block 92, preventing it from rotating synchronously with the ball screw 91 and ensuring the linear motion of the screw nut block. 92 slides smoothly only in the left and right directions. The lead screw nut block 92 is fastened to the left side of the insulation plate 32 by bolts, so that the linear motion of the lead screw nut block 92 can be synchronously transmitted to the insulation plate 32, driving the insulation plate 32 to move along the slide rail 21. This design can control the insulation plate 32 to move to the target position by driving the motor 95 according to the number and distribution of PHA products in the material cavity 12a. For example, when the products are only placed on the right side of the material cavity 12a, the insulation plate 32 can be moved to the corresponding area. In conjunction with the slide rail type drive blade plate 3, the local space of the material cavity 12a can be separated and the temperature controlled, avoiding heat waste.

[0081] The openings of both the main chamber 12 and the deodorizing and purification chamber 13 face forward, and both are connected to the outside of the device. Sealing door plates 72 are mounted and connected to the corresponding positions of the openings of the main chamber 12 and the deodorizing and purification chamber 13 along the opening axis. The core principle of the sealing door plates 72 of the main chamber 12 and the deodorizing and purification chamber 13 is that the openings of both face forward, which conforms to the operator's usual operating habits, facilitating the placement of PHA products into the material chamber 12a of the main chamber 12 from the front, or the replacement and maintenance of the activated carbon placement box 52 in the deodorizing and purification chamber 13 from the front. Simultaneously, both chambers are connected to the outside of the device, ensuring smooth connection between the interior and exterior spaces when open, meeting the needs of material entry and exit and component maintenance.

[0082] In the actual operation of the PHA deodorization device: First, the operator opens the sealing door 72 of the main chamber 12 facing the front of the device. According to the batch of PHA products (such as single basket or multiple baskets discharged from right to left), the drive motor 95 in the guide groove 12a1 behind the material chamber 12a is started. The motor drives the ball screw 91 to rotate. The screw nut block 92 slides left and right under the constraint of the support limit column 93, and simultaneously drives the insulation plate 32 and the connected slide rail type drive blade plate 3 to move to the target position, separating the material chamber 12a space suitable for the number of products. Then, the sealing door 72 of the main chamber 12 is closed. If the activated carbon in the deodorization and purification chamber 13 needs to be replaced, its sealing door 72 can be opened separately to pull out the activated carbon placement box 52 for replacement. After completion, the door is closed to ensure that the two chambers are sealed.

[0083] After the device is started, each module enters a coordinated operation state: the evaporator module 6 introduces airflow through the air inlet grille 642 of the L-shaped ventilation grille 64, and after passing through the evaporator assembly 62, it is conveyed upward by the guide fan 63, and then guided to the left condenser module 8 by the large arc-shaped guide plate 7b; the first guide fan group 83 sends the temperature-controlled airflow into the airflow chamber 12b above the main chamber 12; the transmission assembly 9 drives the sliding rail type drive blade plate 3 to move, and its pressure strip 331 presses the guide heat insulation blade 4 to flip the protrusion 42, so that the corresponding three blades When the blades open (maximum 85°), the hot airflow in the airflow chamber 12b flows into the material chamber 12a through the gap between the blades, acting on the PHA product to accelerate the volatilization of odors; the volatilized odor airflow flows to the right, and after passing through the dustproof layer 7a to filter dust, it enters the deodorization and purification chamber 13. With the cooperation of the second and third guide fan groups 71b, the airflow flows through the activated carbon placement box 52 in the grid base 5 to adsorb odors. After purification, the airflow is guided by the airflow guide plate 7c and flows back to the evaporator module 6 through the return air grid 641, forming a closed loop of airflow circulation.

[0084] During operation, the temperature can be dynamically adjusted according to the needs: if the odor concentration of the product is high, the position of the insulation plate 32 can be finely adjusted by the drive motor 95 to reduce the space of the material chamber 12a and improve the heating efficiency; the rubber sealing strip 73 deforms and seals after the sliding seat connector 33 is in place to prevent air leakage or heat loss. After the device is finished running, the drive motor 95 drives the slide rail type drive blade plate 3 to reset, and then the sealing door plate 72 of the main chamber 12 is opened to take out the PHA product.

If activated carbon needs to be replaced, open the sealing door (72) of the deodorizing and purification chamber (13), pull out and replace the internal activated carbon storage box (52), close the door to ensure the two chambers are sealed, start the device, the evaporator module (6) will process the introduced airflow, guide it through the large arc-shaped guide plate (7b) to the condenser module (8) for secondary temperature control, and then send it into the airflow chamber (12b) through the first guide fan group (83). At the same time, the sliding wheel type drive blade plate (3) presses the flipping protrusion (42) through the pressure strip (331) to open the guide heat insulation blade (4) on its right side to 85°, so that the hot airflow flows into the material chamber to accelerate the volatilization of odors in the PHA products. After the airflow is filtered by the dustproof layer (7a) and purified by activated carbon adsorption in the deodorizing purification chamber (13), the purified airflow is returned to the evaporator module (6) through the airflow guide plate (7c) to form a closed loop. During operation, the position of the heat insulation plate (32) is finely adjusted by the drive motor (95) according to the odor concentration of the product to optimize the heating efficiency. The rubber sealing strip (73) is squeezed by the sliding seat connector (33) to ensure the sealing of the material chamber. After the device is finished running, the sliding wheel drive plate (3) is reset by the drive motor (95), and the guide heat insulation blade (4) is automatically closed under the action of the center of gravity block (41). The main chamber sealing door plate (72) is opened, and the PHA product can be taken out.
