Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, specifically to a deodorization device and a tubular belt conveyor. Background Technology

[0002] Tubular belt conveyors are belt conveyors in which the conveyor belts for both the carrying and return branches are coiled into a tubular shape. They are a new type of conveyor that combines the characteristics of pipeline and belt conveying, featuring a large conveying angle, small radius of curvature, and small cross-sectional area. They can achieve three-dimensional curved conveying, facilitating the layout, maintenance, and management of the conveying line. However, the size of the material is limited by the width of the conveyor belt, making them unsuitable for applications with short conveying lines and multiple receiving or unloading points. They are mainly used for conveying various lumpy and powdery materials such as coal, ore, grain, cement, pulp, waste, and concrete.

[0003] In actual production operations, tubular belt conveyors frequently encounter various problems, significantly impacting production. For example, but not limited to, the odor generated during waste transport cannot be systematically treated. Existing technology typically uses a tubular belt conveyor with a sealed outer cover. Both the head and tail sections of the conveyor are equipped with sealed protective covers and odor extraction devices. A negative pressure is created within the sealed body to centrally treat the extracted waste odor, but this does not allow for the reuse of the treated gas.

[0004] In view of this, there is an urgent need to optimize the design of odor treatment solutions for tubular belt conveyors in order to overcome the above-mentioned defects. Summary of the Invention

[0015] Optionally, the controller may also output a control command to the control terminal of the pumping device based on the signal detected by the sensor, so that the pumping device can be started.

[0016] The present invention also provides a tubular belt conveyor, including a belt and a sealing device covering the outer periphery of the belt, and further including a deodorizing duct and the deodorizing device as described above, wherein the deodorizing duct is in communication with the interior of the sealing device.

[0017] Optionally, it also includes a pneumatic drive device, which includes a storage device and a plurality of annular tubes. The plurality of annular tubes are disposed within the sealing device and surround the outer periphery of the tape. The plurality of annular tubes are spaced apart along the running direction of the tape. The storage device is connected to the exhaust pipe of the deodorizing device and is connected to the plurality of annular tubes located within the sealing device through a main channel.

A first shut-off valve is provided on the communication path of the first side-biased air blow hole, and a second shut-off valve is provided on the communication path of the second side-biased air blow hole. The signal acquisition end of the color recognition device is located on the inner wall surface of the annular tube and is arranged opposite to the second color recognition area.

[0020] Optionally, it also includes a compressed air manifold unit and a third shut-off valve.

[0021] Optionally, the device also includes an intelligent odor detection device, wherein a track is fixedly installed inside the sealing device, the track is arranged along the running direction of the tape, and the intelligent odor detection device can move along the track to detect the odor concentration.

[0022] Compared with existing technologies, this invention proposes a novel solution for the deodorization device. Specifically, the inner cavity of the housing is connected to the sealing device of the tubular belt conveyor via an air inlet pipe, and gas can be discharged through an exhaust pipe. A sprayer is used to spray deodorizing spray into the inner cavity. A filter plate is disposed in the inner cavity of the housing below the air inlet pipe, dividing the inner cavity into an upper processing chamber and a lower liquid storage chamber. With this configuration, the precipitate formed by the deodorization reaction adsorption will adhere to the upper surface of the filter plate. The filtered deodorizing spray passes through the filter plate and forms liquid stored in the lower liquid storage chamber of the deodorization device for reuse, reducing system operating costs. Simultaneously, the gas obtained after treatment by the deodorization device is approximately colorless and odorless, which can be reused after being discharged through the exhaust pipe, further reducing system operating costs.

[0023] In an optional embodiment of the invention, a scraper is further included. The lower edge of the scraper is fitted to the upper surface of the filter plate. The scraper can rotate under the drive of the driving device to scrape off the precipitates adhering to the upper surface of the filter plate. Further, the inner wall of the housing is cylindrical, the side edge of the scraper is fitted to the inner wall of the housing, and the rotation center of the scraper coincides with the center of the cylindrical surface, so as to simultaneously scrape off the precipitates adhering to the inner wall of the housing.

[0024] In another optional embodiment of the present invention, the driving device includes a float plate, a connecting rod, a first sleeve, and a second sleeve; the float plate is placed in the lower liquid storage chamber of the shell and can float up and down with the liquid level, driving the connecting rod of the filter plate to move synchronously, and based on the first sleeve and the second sleeve adapted to the connecting rod, driving the scraper to rotate. The rotation of the scraper can be driven by the change of liquid level, which can further reduce the system operating cost.

[0025] In another alternative embodiment of the present invention, the side wall of the housing is provided with a discharge port, and the discharge port is located at the bottom of the upper processing chamber of the housing to discharge the scraped precipitate to the maximum extent; a collection box is provided on the outside of the housing, and further includes a sealing plate and a driving component. The sealing plate can be switched between an open working position and a closed working position under the drive of the driving component to open or close the discharge port according to the system operating status, so as to discharge the precipitate in a timely and effective manner.

[0026] In another optional embodiment of the invention, a pneumatic drive device is further included. This pneumatic drive device comprises multiple annular tubes disposed within a sealing device and surrounding the outer periphery of the conveyor belt. These annular tubes are spaced apart along the belt's running direction. A main channel connects to each of the annular tubes within the sealing device. Each annular tube has multiple annular tubes arranged circumferentially on its radial inner wall. This arrangement allows the conveyor belt to suspend within the annular tubes, significantly reducing the resistance exerted on the conveyor belt by traditional idlers. Furthermore, the air-blowing holes are inclined towards the belt's running direction, allowing for simultaneous provision of driving force through air blowing.

[0027] In another optional embodiment provided by the present invention, a color recognition device is further included. The outer surface of the tape is configured with a first color recognition area, a second color recognition area, and a third color recognition area arranged circumferentially in sequence. A first side-biased air blowing hole and a second side-biased air blowing hole are provided on the radial inner wall of the annular tube, allowing air to push the tape to rotate clockwise or counterclockwise. The signal acquisition end of the color recognition device is located on the inner wall surface of the annular tube and is positioned opposite to the second color recognition area, at which point the tape is in normal working condition. When the color recognition device identifies the color of the first color recognition area or the third color recognition area, it opens the shut-off valve on the connecting path of the first or second side-biased air blowing hole, allowing air to push the tape to rotate clockwise or counterclockwise until the color of the second color recognition area is identified. This further optimizes the use of treated gas while ensuring the normal operation of the tape, reducing system operating costs. Attached Figure Description

[0037] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Without loss of generality, this embodiment uses the tubular belt conveyor shown in the figure as the main descriptor, and details the treatment solutions provided for specific implementation methods such as odor treatment, recirculation of treated gas, and intelligent odor detection. Please refer to... Figure 1 and Figure 2 ,in, Figure 1 This figure is a schematic diagram of the overall structure of the tubular belt conveyor described in this embodiment. Figure 2 for Figure 1 A partial view in direction A.

[0039] This tubular belt conveyor includes a conveyor belt 10, a sealing device 20, a deodorizing duct 30, a truss body 40, and a deodorizing device 50. The conveyor belt 10 is placed inside the truss body 40, establishing a conveying cycle. The sealing device 20 covers the outer periphery of the conveyor belt 10, forming an internally sealed working environment to prevent odors from escaping and affecting the external environment during the transport of domestic waste. It is understood that the internal seal formed by the sealing device 20 refers to preventing odors from diffusing into the polluted external air. This sealing performance only needs to ensure a basic level of sealing, which can be achieved using existing sealing technologies, and will not be elaborated upon here.

[0040] In this embodiment, the deodorizing duct 30 is internally connected to the sealing device 20, and the sealing device 20 is internally connected to the chamber of the deodorizing device 50. Air can be delivered into the sealing device 20 through the deodorizing duct 30, and odorous gases can be delivered into the deodorizing device 50 to achieve deodorization. For details, please refer to [further details]. Figure 3 The figure is a schematic diagram of the internal structure of the deodorization device described in this embodiment.

[0041] As shown in the figure, the sealing device 20 can be connected to the inner cavity of the deodorizing device 50 through the air inlet pipe 51, and the treated gas can be discharged through the exhaust pipe 52.

[0042] The deodorizing device 50 includes a housing 53 with an inner cavity and a sprayer 54. The sprayer 54 is located above the housing 53 and can be positioned anywhere above the side wall opening communicating with the air inlet pipe 51, rather than being limited to the top of the housing 53 as shown in the figure. A deodorizing spray can be sprayed through the sprayer 54. This spray chemically reacts with the odor and adsorbs particulate matter mixed in the odor, forming a precipitate that settles. The choice of the type and amount of deodorizing spray is not the core inventive point of this application; it can be implemented based on existing technology and will not be elaborated upon here.

[0043] In order to ensure that the gas discharged through the exhaust pipe 52 is fully treated, in this embodiment, the exhaust pipe 52 is set at the top of the housing 53. This allows the discharged gas to be fully treated while also preventing sediment from being discharged mixed in with the gas.

[0044] In this embodiment, the deodorizing device 50 also includes a filter plate 55, which is fixed inside the housing 53 below the air inlet pipe 51, dividing the inner cavity of the housing 53 into an upper processing chamber and a lower liquid storage chamber. The precipitate formed by the deodorization reaction adsorption will adhere to the upper surface of the filter plate 55. The filtered deodorizing spray passes through the filter plate 55 and forms liquid stored in the lower liquid storage chamber of the deodorizing device 50 for reuse, reducing system operating costs.

[0045] In practice, when the amount of stored liquid is large, it can be manually processed for recycling and reuse, or it can be automatically recycled and reused. In this embodiment, the deodorizing device 50 is also equipped with a pumping device 56. The liquid intake port of the pumping device 56 is connected to the liquid storage chamber at the bottom of the housing 53, so as to transport the liquid to the storage tank (not shown in the figure) through its discharge port, so as to enter the next working cycle of spraying deodorizing spray.

[0046] In order to clean the sediment adhering to the upper surface of the filter plate 55 in a timely manner, a scraper 57 can be arranged above the filter plate 55. The scraper 57 fits properly with the upper surface of the filter plate 55, and the rotation center of the scraper 57 coincides with the geometric center of the filter plate 55 in the vertical direction. Thus, it can rotate under the drive of the drive device to scrape off the sediment.

[0047] Of course, the precipitate will also adhere to the inner wall of the shell 53. The inner wall of the shell 53 can be cylindrical, so that the outer edge of the scraper 57 can fit snugly against the inner wall of the shell 53, and can scrape off the precipitate deposited on the inner wall of the shell 53 at the same time.

[0048] In this embodiment, the driving force for rotating the scraper 57 is provided based on the liquid level change of the deodorizing spray stored in the lower liquid storage chamber, which is achieved through the compatible float 58, connecting rod 59, first sleeve 510 and second sleeve 511.

[0049] Specifically, the float 58 is placed in the lower liquid storage cavity of the shell 53 and can float up and down with the liquid level. The linkage rod 59 passes through the center of the filter plate 55 and its lower end is fixedly connected to the float 58.

[0050] The linkage 59 has an external threaded section, which is adapted to the internal thread of a fixed first sleeve 510. The first sleeve 510, as shown, is fixed to the filter plate 55 and has an internal thread that matches the external thread of the linkage 59. Thus, when the linkage 59 moves up and down, it will rotate synchronously based on this threaded adaptation. To improve the stability of the linkage 59's vertical movement, in this embodiment, two first sleeves 510 are spaced apart along the length of the linkage 59.

[0051] Of course, in other specific implementations, the first sleeve 510 can also be fixed to the housing 53 (not shown in the figure).

[0052] The second sleeve 511 is located on the filter plate 55, and the scraper 57 is fixedly connected to the second sleeve 511. The second sleeve 511 and the filter plate 55 can rotate relative to each other, and the two are limited in the height direction. That is, during the operation, the second sleeve 511 can have rotational freedom relative to the filter plate 55, and the relative position between the two in the height direction remains unchanged.

[0053] Correspondingly, the second sleeve 511 has a slider 5111 protruding from its inner wall, and the upper end of the connecting rod 59 may have a groove (not shown in the figure) extending along its length. The slider 5111 is built into the groove on the connecting rod 59, and the two are slidably adapted to each other. Thus, when the connecting rod 59 moves up and down, based on this sliding adaptation relationship, the second sleeve 511 will rotate, thereby driving the scraper 57 to rotate. As a result, the precipitates adhering to the upper surface of the filter plate 55 and the inner wall of the housing 53 will be scraped off, ensuring the cleanliness of the inside of the deodorizing device 50 and making the filter plate 55 less prone to clogging by precipitates.

[0054] In other specific implementations, the drive device for rotating the scraper 57 can be a motor (not shown in the figure), that is, the scraper 57 is rotated by a motor.

[0055] In this embodiment, the filter plate 55 is generally conical with a convex upper part in the middle, and the scraper 57 is correspondingly inclined at its lower edge. During the process of the scraper 57 cleaning the sediment on the upper surface of the filter plate 55 and the inner wall of the housing 53, the sediment on the inner wall of the housing 53 will gradually fall to the upper surface of the filter plate 55, and the sediment on the upper surface of the filter plate 55 will gradually slide to the edge, which can avoid affecting the filtration effect. In addition, the scraper 57 is generally triangular frame-shaped, which can ensure the structural strength of the scraper 57 itself.

[0056] Furthermore, in order to promptly remove sediment, the deodorization device provided in this implementation plan has an automatic impurity removal function. For example... Figure 3 As shown, the side wall of the housing 53 is provided with a discharge port 531, which is located at the bottom of the processing chamber, that is, adjacent to the filter plate 55 on the side wall of the housing 53, so as to discharge the scraped sediment to the maximum extent.

[0057] In this embodiment, a collection box 512 is provided on the outside of the housing 53, located below the discharge port 531, so that the sediment can be drawn out through the discharge port 531 into the collection box 512. Simultaneously, a sealing plate 513 and an electric cylinder 514 are also provided on the housing 53. The sealing plate 513 can move under the drive of the output end of the electric cylinder 514 to switch between an open working position and a closed working position. In the closed working position, the sealing plate 513 will close the discharge port 531; in the open working position, the sealing plate 513 will move away from the discharge port 531 to allow the sediment to be discharged.

[0058] To enable automatic control of the working position switching of the enclosed plate 513, a sensor 515 and a controller 516 can be used. The signal collected by the sensor 515 is sent to the controller 516, which then controls the operation of the electric cylinder 514 according to the control strategy.

[0059] In this embodiment, the sensor 515 can be configured inside the housing 53 and positioned above the scraper 57 to avoid interference with the rotating scraper 57, and is used to detect the working position of the scraper 57. Specifically, when the scraper 57 rotates from one side of the discharge port 531, rotates more than 180° and moves to the other side of the discharge port 531, the scraper 57 rotates to below the sensor 515. At this time, the sensor 515 will detect the scraper 57 and send a signal to the controller 516. The controller 516 outputs a control command to the control cylinder 514. The start of the cylinder 514 will drive the sealing plate 513 to rise, so that the discharge port 531 opens, allowing the sediment scraped by the scraper 57 to be discharged through the discharge port 531 into the collection box 512 on the outer wall of the housing 53. Then, the cylinder will drive the sealing plate to fall, and the sealing plate will close the discharge port 531, making it difficult for the deodorizing spray falling on the filter plate 55 to flow out through the discharge port 531, reducing the waste of deodorizing spray.

[0060] Here, sensor 515 can be an infrared sensor. In other specific implementations, sensor 515 can also be other types of sensors, as long as they can meet the functional requirements of signal acquisition.

[0061] Of course, the activation time of the pumping device 56 can also be controlled by the controller 516. For example, but not limited to, when the electric cylinder 514 starts and drives the sealing plate 513 to rise, a control command is output to start the pumping device 56. In specific implementations, the two can also be controlled according to different control strategies, rather than being limited to synchronous actions.

[0062] Alternatively, in a practical implementation, the start-up control of the electric cylinder 514 can be based on the thickness of the deposit layer. In a practical implementation, the electric cylinder 514, as the driving component, can also be replaced by a pneumatic cylinder (not shown in the figure), which can similarly drive the sealing plate 513 to switch working positions.

[0063] It should be noted that, under the extraction of the pumping device 56, the float 58 descends due to the drop in the deodorizing spray liquid level in the bottom storage chamber of the housing 53. The connecting rod 59 moves downwards synchronously, causing the scraper 57 to rotate in the opposite direction and further clean the sediment adhering to the upper surface of the filter plate 55 and the inner wall of the housing 53, thereby improving the treatment effect on the sediment. Here, the connecting rod 59 can be made heavier through material selection or structural design, acting as a counterweight during the descent of the float 58. It descends and resets under its own weight, exhibiting good dynamic performance.

[0064] For the recirculation of the treated gas, after treatment by the deodorization device 50, a generally colorless and odorless harmless gas is obtained. In this embodiment, a storage device 60 is configured to store the treated gas. The deodorization device 50 is connected to the storage device 60 through an exhaust pipe 52. The storage device 60 can be transported to the inside of the sealing device 20 through the main channel 61, and then enters the annular tube 70 surrounding the outer circumference of the tape 10. Air is blown through the air blowing holes 71 opened on the annular tube 70 to suspend the tape 10, providing a suspending function. Please refer to [further details omitted]. Figure 2 , Figure 4 and Figure 5 ,in, Figure 4 This is a schematic diagram of the gas-driven device described in this embodiment. Figure 5 for Figure 4 The diagram shows the structure of the annular tube.

[0065] The radial outer wall of the annular tube 70 is connected to the main channel 61, and the air blowing holes 71 are arranged circumferentially on the radial inner wall of the annular tube 70, which allows the tape 10 to be suspended inside the annular tube 70, greatly reducing the resistance of the tape generated by the traditional idler roller.

[0066] Further, please see Figure 6The first figure is a schematic diagram of the structure of the air blowing hole in the annular tube, and the second figure is a partial cross-sectional view formed along the running direction of the conveyor belt.

[0067] The air blowing holes 71 on the annular tube 70 are inclined towards the running direction of the conveyor belt 10, so that air blowing suspends the conveyor belt while providing driving force. In specific implementations, the annular tube 70 can be spaced according to the actual support and driving function requirements, that is, spaced along the running direction of the conveyor belt 10 as shown in the figure.

[0068] Analysis of the suspended tape revealed that, apart from the radial force on the tape itself, there was virtually no circumferential force. Therefore, to prevent the tape from deviating, the gas-driven device incorporated a color recognition scheme. For example... Figure 4 As shown, the outer surface of the tape 10 is provided with a first color recognition area 11, a second color recognition area 12, and a third color recognition area 13 arranged circumferentially. For example, but not limited to, the first color recognition area 11 is painted green, the second color recognition area 12 is painted red, and the third color recognition area 13 is painted yellow. In other specific implementations, the three color recognition areas are not limited to the above three colors, and the recognition areas can also be implemented by a process of bonding color layers.

[0069] Correspondingly, a color recognition device 72 is provided on one side of the annular tube 70, and a first side-biased air blowing hole 73 and a second side-biased air blowing hole 74 are provided on the radial inner wall of the annular tube 70. Both can be connected to the main channel 61, and a first shut-off valve 75 is provided on the communication path of the first side-biased air blowing hole 73, and a second shut-off valve 76 is provided on the communication path of the second side-biased air blowing hole 74. In this embodiment, the first side-biased air blowing hole 73 and the second side-biased air blowing hole 74 are located at the lower right and lower left of the tape 10, respectively, and can be used to push the tape 10 to rotate clockwise or counterclockwise by air blowing.

[0070] The signal acquisition end of the color recognition device 72 is located on the inner wall of the annular tube 70. If the color recognition device 72 identifies red, that is... Figure 4 If the indicated state is yellow, it is determined that the conveyor belt 10 is misaligned counterclockwise. In this case, the controller 516 opens the normally closed first shut-off valve 75, and applies a clockwise force to the conveyor belt 10 through the first side-biasing air blow hole 73 to adjust its alignment until it is identified as red, at which point the first shut-off valve 75 is closed. If the indicated state is green, it is determined that the conveyor belt 10 is misaligned clockwise. In this case, the controller 516 opens the normally closed second shut-off valve 76, and applies a counterclockwise force to the conveyor belt through the second side-biasing air blow hole 74 to adjust its alignment until it is identified as red, at which point the second shut-off valve 76 is closed. Thus, misalignment is determined by a color recognition device, and misalignment is corrected using odorous gas.

[0071] In addition, the gas-driven device is designed with an anti-clogging design for the air blow-out holes. A separate compressed air unit 80 is designed to compress the processed gas into the compressed air unit 80. That is, the air inlet of the compressed air unit 80 is connected to the main channel, and the high-pressure gas outlet of the compressed air unit 80 is connected to the annular pipe 70. A normally closed third shut-off valve 81 is provided on the connection path. The third shut-off valve 81 can be set to open at intervals to blow out foreign objects blocking the air blow-out holes through short-term instantaneous high pressure, ensuring the normal operation of the entire gas-driven device.

[0072] In addition, a fourth shut-off valve 62 can be installed on the main channel 61 to open or close the channel as needed, facilitating operation and maintenance.

[0073] For intelligent odor detection, this implementation scheme is equipped with an operating track 91 for the intelligent odor detection device 90. This track 91 is arranged along the running direction of the conveyor belt 10, allowing the intelligent odor detection device 90 to move along the track 91 and inspect the operation of the entire conveyor belt. Please refer to [link / reference]. Figure 7 The figure shows the assembly relationship of the intelligent odor inspection device 90.

[0074] Specifically, the track 91 can be made of I-beams and fixed to the truss structure inside the sealing device 20 by brackets. The head and tail of the I-beams terminate at the head and tail extension sections and can be isolated from the head and tail extension sections, allowing inspection of the entire conveyor belt area except for the head and tail sections. The intelligent odor inspection device 90 determines whether the conveyor belt is operating normally by setting the odor concentration area. When the conveyor belt starts operating, the intelligent odor detection device 90 is activated, inspecting from the tail to the head and then back again, repeating the inspection process. For example, but not limited to, during the inspection, the odor concentration in the area is detected. If the odor concentration is within the range of 30-60, the conveyor belt is considered to be operating normally. If the detected odor concentration is less than 30, it is determined that the conveyor belt is not conveying domestic waste or is conveying other incorrect materials, and the intelligent odor detection device issues an alarm signal. If the detected odor concentration is within the range of 30-60, the conveyor belt is considered to be operating normally. If the detected odor concentration exceeds 60, it is determined that the conveyor belt has experienced a pipe burst, belt breakage, or is about to experience belt overlap, and the intelligent odor detection device issues an alarm signal and simultaneously issues a command to stop the conveyor belt.

[0075] It should be noted that the specific functions of the shut-off valve, compressed air manifold unit 80, and intelligent odor detection device 90 used in the embodiments of this application are not the core inventive point of this application. Those skilled in the art can implement them based on existing technology, so they will not be described in detail here.

[0076] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
