Description

Technical Field

[0001] This utility model specifically relates to a filter product dryer. Background Technology

[0002] Chinese utility model patent document with publication number "CN206523019U" discloses a dryer, which mainly includes a frame, a metal woven mesh conveyor belt, a drive motor linked to the conveyor belt, a shell, heating wires installed inside the shell, and an exhaust fan. The upper and lower covers of the filter paper core enter the drying device through the metal woven mesh conveyor belt. The stainless steel heating rods (on both sides and at the bottom) inside the drying device are energized and heated to a specific temperature. Through heating and melting and precise temperature control, the residual insulating material on the surface of the upper and lower covers of the filter paper core is automatically and thoroughly removed without manual scraping.

[0003] The dryer has the following defects: it only has one conveyor belt and is driven by a drive motor. It does not make reasonable use of the drying area inside the shell. When the filter passes through the dryer, the drying efficiency is low and it cannot be thoroughly dried. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a filter product dryer to address the shortcomings of the prior art, improve the drying efficiency of filters, optimize the path through multiple sets of conveyor belts and steering components, adapt to automated production and reduce energy consumption.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter product dryer, including a frame, a drying device mounted on the frame, and a conveying assembly for driving several filters through the inner cavity of the drying device, characterized in that: the conveying assembly includes several sets of main conveyor belts arranged in parallel with each other, a main drive mechanism for driving the several sets of main conveyor belts to move, and a turning conveyor belt assembly is respectively provided between one end of each set of main conveyor belts and the adjacent main conveyor belt on the left, and between the other end of each set of main conveyor belts and the adjacent main conveyor belt on the right.

[0006] Using the above technical solution, several sets of main conveyor belts are arranged in parallel along the inner cavity of the drying device. After the filter enters the drying area from the initial main conveyor belt, it is sequentially transferred to adjacent main conveyor belts through the deflecting conveyor belt assembly at the end, forming a "serpentine" conveying path. The main drive mechanism drives all main conveyor belts, causing the filter to move continuously along the drying path within the drying device until it is dried and output from the end main conveyor belt. This solution, through the arrangement of multiple sets of parallel main conveyor belts, divides the lateral space inside the drying device into multiple parallel conveying channels. Combined with the deflecting assembly, it enables the filter to move back and forth, making full use of the drying area and multiplying the number of filters that can be processed per unit time, directly improving drying efficiency. Furthermore, the deflecting conveyor belt assembly extends the conveying path of the filter within the drying device, significantly increasing the residence time of the filter in the high-temperature area without increasing the overall length of the device. Simultaneously, the parallel arrangement of multiple sets of main conveyor belts ensures that each filter receives uniform heating from the heating wires on both sides and the bottom, avoiding uneven heating caused by positional deviations in filters on a single conveyor belt.

[0007] The aforementioned filter product dryer can be further configured such that: the steering conveyor belt assembly includes a first auxiliary conveyor belt connected to a set of main conveyor belts and moving in the same direction as the main conveyor belts, a second auxiliary conveyor belt connected to an adjacent main conveyor belt and moving in the same direction as the main conveyor belts, and a third auxiliary conveyor belt connecting the first auxiliary conveyor belt and the second auxiliary conveyor belt; the steering conveyor belt assembly also includes a steering drive mechanism that drives the first auxiliary conveyor belt, the third auxiliary conveyor belt, and the second auxiliary conveyor belt to work simultaneously.

[0008] Using the above technical solution, the first auxiliary conveyor belt receives the filters transported by the preceding main conveyor belt, and its movement direction is consistent with the main conveyor belt. The third auxiliary conveyor belt laterally connects the first and second auxiliary conveyor belts. Through the synchronous drive of the steering drive mechanism, it laterally transfers the filters from the first auxiliary conveyor belt to the second auxiliary conveyor belt. The movement direction of the second auxiliary conveyor belt is consistent with the adjacent main conveyor belt, smoothly feeding the filters into the next set of main conveyor belts, forming a continuous drying path of "main conveyor belt straight conveying, steering assembly lateral reversal, and main conveyor belt straight conveying". By adapting the directions of the first and second auxiliary conveyor belts to the preceding and following main conveyor belts, respectively, and through the lateral connection of the third auxiliary conveyor belt, jamming or tipping of the filters during reversal is avoided. The steering drive mechanism synchronously drives the three auxiliary conveyor belts, ensuring speed matching and maintaining a stable posture for the filters during reversal, reducing the risk of conveying failure.

[0009] The aforementioned filter product dryer can be further configured such that: the steering drive mechanism includes a steering main drive rod linked to the third auxiliary conveyor belt, a steering auxiliary transmission rod linked to the second auxiliary conveyor belt, and a steering auxiliary driven rod linked to the first auxiliary conveyor belt; one end of the steering main drive rod is linked to a third motor, and the other end is linked to a main bevel gear; the steering auxiliary transmission rod is provided with a secondary bevel gear and a first gear; the secondary bevel gear meshes with the main bevel gear; and the steering auxiliary driven rod is provided with a second gear meshing with the first gear.

[0010] Using the above technical solution, the third motor drives the main steering drive rod to rotate (the third auxiliary conveyor belt runs accordingly). The main drive rod, through the meshing of the main bevel gear and the secondary bevel gear, drives the steering auxiliary transmission rod to rotate, which in turn drives the second auxiliary conveyor belt. Simultaneously, the steering auxiliary transmission rod, through the meshing of the first gear and the second gear, drives the steering auxiliary driven rod to rotate, driving the first auxiliary conveyor belt to run at the same time. This steering drive mechanism enables one motor to drive three sets of auxiliary conveyor belts simultaneously, reducing the number of core components such as motors and controllers, and lowering costs. Furthermore, the gear meshing transmission provides high transmission efficiency.

[0011] The aforementioned filter product dryer can be further configured such that: the first auxiliary conveyor belt and the second auxiliary conveyor belt are parallel to each other, and the third auxiliary conveyor belt is perpendicular to the first auxiliary conveyor belt; the steering conveyor belt assembly also includes U-shaped guardrails distributed on the outer rings of the first auxiliary conveyor belt, the second auxiliary conveyor belt, and the third auxiliary conveyor belt.

[0012] Using the above technical solution, the arrangement of the three sets of auxiliary conveyor belts makes the turning path form a right angle, and the U-shaped guardrail guides the filter to prevent it from deviating from the path due to inertia when turning at high speed.

[0013] The aforementioned filter product dryer can be further configured as follows: the main drive mechanism includes a first drive shaft, a first motor driving the first drive shaft to rotate, a second drive shaft, and a second motor driving the second drive shaft to rotate; several sets of main conveyor belts include a left conveyor belt, a middle conveyor belt, and a right conveyor belt arranged parallel to each other and spaced apart; one end of the left conveyor belt is linked to a first gear set, and the other end is linked to a second gear set, the first gear set is mounted on the first drive shaft and the two rotate synchronously, and the second gear set is loosely fitted on the second drive shaft through a bearing; one end of the right conveyor belt is linked to a third gear set, and the other end is linked to a fourth gear set, the third gear set is mounted on the first drive shaft and the two rotate synchronously, and the fourth gear set is loosely fitted on the second drive shaft through a bearing; one end of the middle conveyor belt is linked to a fifth gear set, and the other end is linked to a sixth gear set, the fifth gear set is mounted on the second drive shaft and the two rotate synchronously, and the sixth gear set is loosely fitted on the second drive shaft through a bearing.

[0014] Using the above technical solution, a first motor drives a first drive shaft to rotate, synchronously driving the left and right conveyor belts through a first and third gear set fixed on the shaft. This ensures that the left and right conveyor belts transport goods in the same direction at the same speed. A second motor drives a second drive shaft to rotate, driving the middle conveyor belt through a fifth gear set fixed on the shaft. The second gear set at the other end of the left conveyor belt and the fourth gear set at the other end of the right conveyor belt are each loosely fitted onto the second drive shaft via bearings. Similarly, the sixth gear set at the other end of the middle conveyor belt is loosely fitted onto the second drive shaft via bearings, preventing interference between the conveyor belts during operation. Synchronizing the left and right conveyor belts through the first drive shaft ensures synchronized operation while reducing costs.

[0015] The aforementioned filter product dryer can be further configured such that: the other end of the left conveyor belt is provided with a feeding section extending toward the outside of the drying device; the end of the feeding section away from the second drive shaft is linked to a seventh gear set; the seventh gear set is connected to a support shaft through bearings; the two ends of the support shaft are mounted on the frame; a water collection tank is provided below the feeding section; a guide plate is provided between the water collection tank and the feeding section; the end of the guide plate near the support shaft is inclined toward the water collection tank.

[0016] Using the above technical solution, the feeding section extends from the end of the left conveyor belt towards the outside of the drying device. Its end is linked to the support shaft (fixed to the frame) via the seventh gear set, forming a feeding platform. When the filter enters the feeding section, the residual liquid on its surface drips onto the guide plate below under gravity. The inclined guide plate directs the liquid to the collection tank for centralized collection. The seventh gear set is connected to the support shaft via bearings, ensuring synchronous operation of the feeding section on the left conveyor belt and achieving a smooth transition of the filter to the drying area.

[0017] The aforementioned filter product dryer can be further configured such that: a buffer assembly connected to the feed section is installed on the frame, the buffer assembly including a buffer frame installed on the frame and several sets of buffer rollers rotatably installed on the buffer frame.

[0018] By adopting the above technical solution, the filter will be pushed onto the buffer assembly before entering the feeding section, and will not enter the feeding section immediately. This makes it easier to control the spacing between the filters entering the drying device and improves the drying efficiency.

[0019] The aforementioned filter product dryer can be further configured as follows: the drying device includes an outer cover with a drying chamber inside, a lower exhaust assembly distributed below several sets of main conveyor belts for upward exhaust, an upper exhaust assembly distributed above several sets of main conveyor belts for downward exhaust, and a heating lamp assembly distributed on both sides of several sets of main conveyor belts between the upper exhaust assembly and the several sets of main conveyor belts.

[0020] Using the above technical solution, the outer cover forms a closed drying chamber to reduce heat loss. The lower exhaust assembly discharges hot air upwards, and the upper exhaust assembly discharges hot air downwards, so that the air inside the outer cover circulates. The heating lamp assembly is distributed above and on both sides of the main conveyor belt, directly radiating heat to the filter. At the same time, the convective airflow evenly transfers heat to the surface and internal pores of the filter, accelerating moisture evaporation.

[0021] The aforementioned filter product dryer can be further configured such that the lower exhaust assembly includes an exhaust motor and infrared lamps surrounding the exhaust motor.

[0022] Using the above technical solution, the infrared lamps generate infrared radiation after being powered on, directly heating the air around the motor and the airflow passing through it, forming high-temperature hot air. This hot air is then expelled upwards by the exhaust motor, passing through the gaps in the main conveyor belt and acting on the bottom of the filter.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1 to 7 The filter product dryer shown includes a frame, a drying device mounted on the frame, and a conveying assembly for driving several filters through the inner cavity of the drying device. The conveying assembly includes several sets of main conveyor belts a arranged in parallel with each other, and a main drive mechanism for driving the several sets of main conveyor belts a to move. Each set of main conveyor belts a has a deflecting conveyor belt assembly b between one end of the main conveyor belt a and the adjacent main conveyor belt a on the left, and between the other end of the main conveyor belt a and the adjacent main conveyor belt a on the right.

[0034] The drying device includes an outer cover 1 with an internal drying chamber, a lower exhaust assembly distributed below several main conveyor belts a for upward airflow, and an upper exhaust assembly 15 distributed above several main conveyor belts a for downward airflow. Heating lamp assemblies 4, distributed on both sides of the main conveyor belts a, are also provided between the upper exhaust assembly 15 and the main conveyor belts a. The outer cover 1 forms a closed drying chamber to reduce heat loss. The lower exhaust assembly discharges hot air upwards, and the upper exhaust assembly 15 discharges hot air downwards, causing air circulation within the outer cover 1. The heating lamp assemblies 4, distributed above and on both sides of the main conveyor belts a, directly radiate heat to the filter, while the convective airflow evenly transfers heat to the filter surface and internal pores, accelerating moisture evaporation.

[0035] The downdraft assembly includes an exhaust motor 2 and infrared lamps 3 surrounding the exhaust motor 2. When energized, the infrared lamps 3 generate infrared radiation, directly heating the air around the motor and the airflow passing through, creating high-temperature hot air. This hot air is then expelled upwards by the exhaust motor 2, passing through the gaps in the main conveyor belt a and acting on the bottom of the filter.

[0036] The steering conveyor belt assembly b includes a first auxiliary conveyor belt b1 connected to a set of main conveyor belts a and moving in the same direction as them, a second auxiliary conveyor belt b2 connected to an adjacent main conveyor belt a and moving in the same direction as it, and a third auxiliary conveyor belt b3 connecting the first auxiliary conveyor belt b1 and the second auxiliary conveyor belt b2. The steering conveyor belt assembly b also includes a steering drive mechanism that drives the first auxiliary conveyor belt b1, the third auxiliary conveyor belt b3, and the second auxiliary conveyor belt b2 to work simultaneously. The first auxiliary conveyor belt b1 receives the filter conveyed by the previous set of main conveyor belts a, and its moving direction is the same as that of the main conveyor belts a. The third auxiliary conveyor belt b3 laterally connects the first auxiliary conveyor belt b1 and the second auxiliary conveyor belt b2. Through the synchronous drive of the steering drive mechanism, it laterally transfers the filter from the first auxiliary conveyor belt b1 to the second auxiliary conveyor belt b2. The second auxiliary conveyor belt b2 moves in the same direction as the adjacent main conveyor belt a, smoothly feeding the filter into the next set of main conveyor belts a, forming a continuous drying path of "main conveyor belt a straight conveying, steering assembly laterally reversing, and main conveyor belt a straight conveying". By adapting the first and second auxiliary conveyor belts b2 to the directions of the front and rear main conveyor belts a, respectively, and by laterally connecting the third auxiliary conveyor belt b3, jamming or tipping during filter reversal is avoided. The steering drive mechanism synchronously drives the three auxiliary conveyor belts to ensure speed matching, keeping the filter in a stable posture during reversal and reducing the risk of conveyor failure.

[0037] The steering drive mechanism includes a main steering drive rod b4 linked to the third auxiliary conveyor belt b3, a steering auxiliary transmission rod b5 linked to the second auxiliary conveyor belt b2, and a steering auxiliary driven rod b12 linked to the first auxiliary conveyor belt b1. One end of the main steering drive rod b4 is linked to a third motor b6, and the other end is linked to a main bevel gear b7. The steering auxiliary transmission rod b5 is equipped with a secondary bevel gear b8 and a first gear b9, with the secondary bevel gear b8 meshing with the main bevel gear b7. The steering auxiliary driven rod b12 is equipped with a second gear b10 meshing with the first gear b9. The third motor b6 drives the main steering drive rod b4 to rotate (and the third auxiliary conveyor belt b3 moves accordingly). The main drive rod, through the meshing of the main bevel gear b7 and the secondary bevel gear b8, drives the steering auxiliary transmission rod b5 to rotate, causing it to drive the second auxiliary conveyor belt b2. Simultaneously, the steering auxiliary transmission rod b5, through the meshing of the first gear b9 and the second gear b10, drives the steering auxiliary driven rod b12 to rotate, driving the first auxiliary conveyor belt b1 to run concurrently. This steering drive mechanism enables one motor to drive three sets of auxiliary conveyor belts simultaneously, reducing the number of core components such as motors and controllers, and lowering costs. Meanwhile, the gear meshing transmission provides high transmission efficiency.

[0038] The first auxiliary conveyor belt b1 is parallel to the second auxiliary conveyor belt b2, and the third auxiliary conveyor belt b3 is perpendicular to the first auxiliary conveyor belt b1. The steering conveyor belt assembly b also includes U-shaped guardrails b11 distributed around the outer rings of the first auxiliary conveyor belt b1, the second auxiliary conveyor belt b2, and the third auxiliary conveyor belt b3. The arrangement of the three auxiliary conveyor belts makes the steering path form a right angle, and the U-shaped guardrails b11 guide the filter to prevent it from deviating from the path due to inertia during high-speed steering.

[0039] The main drive mechanism includes a first drive shaft 5, a first motor 6 driving the first drive shaft 5, a second drive shaft 7, and a second motor 8 driving the second drive shaft 7. Several main conveyor belts a include a left conveyor belt a1, a middle conveyor belt a2, and a right conveyor belt a3 arranged parallel to each other and spaced apart. One end of the left conveyor belt a1 is connected to a first gear set 5-1, and the other end is connected to a second gear set 7-1. The first gear set 5-1 is mounted on the first drive shaft 5, and the two rotate synchronously. The second gear set 7-1 is loosely fitted onto the second drive shaft 5 via a bearing. On drive shaft 7, one end of the right conveyor belt a3 is linked to a third gear set 5-2, and the other end is linked to a fourth gear set 7-2. The third gear set 5-2 is mounted on the first drive shaft 5 and rotates synchronously with it. The fourth gear set 7-2 is loosely fitted onto the second drive shaft 7 via a bearing. One end of the middle conveyor belt a2 is linked to a fifth gear set 7-3, and the other end is linked to a sixth gear set 5-3. The fifth gear set 7-3 is mounted on the second drive shaft 7 and rotates synchronously with it. The sixth gear set 5-3 is loosely fitted onto the second drive shaft 7 via a bearing. The first motor 6 drives the first drive shaft 5 to rotate, which synchronously drives the left and right conveyor belts a3 through the first gear set 5-1 and the third gear set 5-2 fixed on the shaft. This ensures that the left and right conveyor belts a3 transport materials in the same direction at the same speed. The second motor 8 drives the second drive shaft 7 to rotate, which drives the middle conveyor belt a2 through the fifth gear set 7-3 fixed on the shaft. The second gear set 7-1 at the other end of the left conveyor belt a1 and the fourth gear set 7-2 at the other end of the right conveyor belt a3 are both loosely fitted onto the second drive shaft 7 via bearings. Similarly, the sixth gear set 5-3 at the other end of the middle conveyor belt a2 is loosely fitted onto the second drive shaft 7 via bearings, thus preventing interference between the conveyor belts during operation. The first drive shaft 5 drives the left and right conveyor belts a3 to move synchronously, ensuring synchronized operation and reducing costs.

[0040] The other end of the left conveyor belt a1 is also provided with a feeding section a4 extending towards the outside of the drying device. The end of the feeding section a4 away from the second drive shaft 7 is linked to a seventh gear set 9. The seventh gear set 9 is connected to a support shaft 10 through bearings. The two ends of the support shaft 10 are mounted on the frame. A water collection tank 11 is provided below the feeding section a4. A guide plate 12 is provided between the water collection tank 11 and the feeding section a4. The end of the guide plate 12 near the support shaft 10 is inclined towards the water collection tank 11. The feeding section a4 extends from the end of the left conveyor belt a1 towards the outside of the drying device. Its end is linked to the support shaft 10 (the support shaft 10 is fixed to the frame) through the seventh gear set 9, forming a feeding platform. When the filter enters the feeding section a4, the residual liquid on the surface drips down to the guide plate 12 below under the action of gravity. The inclined guide plate 12 guides the liquid to the water collection tank 11 for collection. The seventh gear set 9 is connected to the support shaft 10 through a bearing to ensure that the feed section a4 on the left conveyor belt a1 operates synchronously, so as to achieve a smooth transition of the filter to the drying area.

[0041] A buffer assembly connected to the feed section a4 is installed on the frame. The buffer assembly includes a buffer frame 13 mounted on the frame and several sets of buffer rollers 14 rotatably mounted on the buffer frame 13. Before entering the feed section a4, the filter is pushed onto the buffer assembly and will not enter the feed section a4 immediately. This facilitates control of the spacing between the filters entering the drying device and improves drying efficiency.

[0042] In this embodiment, three sets of conveyor belts are arranged parallel to each other along the inner cavity of the drying device. The filters enter the drying area inside the outer casing 1 through the feed section a4 on the left conveyor belt a1, and are then sequentially transferred to the adjacent main conveyor belt a via the deflecting conveyor belt assembly b at the end, forming a "serpentine" conveying path. The main drive mechanism drives all the main conveyor belts a, causing the filters to continuously move along the drying path within the drying device until drying is complete and they are output from the end main conveyor belt a. This scheme, through the arrangement of multiple sets of parallel main conveyor belts a, divides the lateral space inside the drying device into multiple parallel conveying channels. Combined with the deflecting assembly, this enables the filters to move back and forth, making full use of the drying area and multiplying the number of filters that can be processed per unit time, directly improving drying efficiency. Furthermore, the deflecting conveyor belt assembly b extends the conveying path of the filters within the drying device, significantly increasing the residence time of the filters in the high-temperature area without increasing the overall length of the device. Meanwhile, the parallel arrangement of multiple main conveyor belts a allows each filter to be evenly heated by the heating wires on both sides and at the bottom, avoiding uneven heating caused by positional deviations of filters in a single conveyor belt.
