Description

Technical Field

[0001] This invention relates to the field of waste gas treatment equipment technology, specifically to a waste gas treatment equipment for conveyor belt processing. Background Technology

[0002] Conveyor belts, also known as transport belts, are composite products made of polymers and fibers used in belt conveyors to carry and transport materials. During their production, plastic waste gas pollution is generated, so the waste gas generated during the production process needs to be treated.

[0003] For example, Chinese utility model patent CN218653704U discloses a "waste gas treatment device for conveyor belt processing," whose main structure includes a dust collection hood, a pipe fixed to the right side of the dust collection hood, a primary filter box fixed to the right side of the pipe, a purification box fixed to the right side of the primary filter box, a fan fixed to the right side of the purification box, and an exhaust pipe fixed to the top of the fan. A first mounting base is mounted on the top left side of the primary filter box, with a primary filter screen inserted into the bottom of the first mounting base. A second mounting base is mounted on the top right side of the primary filter box, with an activated carbon filter element inserted into the bottom of the second mounting base. This waste gas treatment device for conveyor belt processing utilizes a high-energy UV beam tube to break the molecular bonds of bacteria in odorous gases, destroying the bacteria's nucleic acid (DNA), and then uses ozone for oxidation, thoroughly achieving deodorization and sterilization.

[0004] As described above, the exhaust gas treatment device for conveyor belt processing first draws the exhaust gas into parallel filters. The filters block impurities, and the pre-filtered gas is then introduced into parallel high-energy UV beam tubes. These tubes break the molecular bonds of bacteria in the odorous gas, destroying their nucleic acid (DNA) to eliminate the bacteria. However, the parallel design of both the filters and the high-energy UV beam tubes means the gas can only flow in one direction. This unidirectional flow leads to low gas treatment efficiency. Furthermore, when the exhaust gas flows in one direction into the high-energy UV beam tubes, the tubes can only maximize the sterilization effect on bacteria in one direction, resulting in overall low efficiency. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a waste gas treatment device for conveyor belt processing. Placed in an area with high waste gas concentration, it allows the gas to be drawn in from all sides via filtration, thereby achieving gas filtration and increasing the gas intake volume. Furthermore, the device can guide the pre-filtered waste gas to the vicinity of a high-energy UV beam tube, enabling the high-energy UV beam tube to perform a wide-area sterilization effect on the surrounding waste gas, thus improving the equipment's working efficiency and solving the aforementioned technical problems.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1A waste gas treatment device for conveyor belt processing includes a vertical hollow shell 1 with an internal air sterilization chamber 2, a support base plate 3 located directly below the vertical hollow shell 1, a longitudinal support rod 8 for fixing and connecting the vertical hollow shell 1 and the support base plate 3, a support leg 5 installed at the bottom of the support base plate 3, a drive motor 6 installed at the bottom of the support base plate 3, an annular filter screen 9 installed in the middle area of ​​the circumferential surface of the vertical hollow shell 1, a high-energy UV beam tube 11 installed at the axial center of the air sterilization chamber 2 via a fixing plate base 10, a gas exhaust port 14 located at the bottom end of the vertical hollow shell 1, and a turbine fan blade 15 located inside the gas exhaust port 14 and rotating with the rotor 7 of the drive motor 6. In order to have directional gas driving capability, the turbine fan blade 15 needs to be driven by the motor. When the rotor 7 of the drive motor 6 rotates, the gas flow direction formed by the turbine fan blades 15 is from top to bottom. When installing the equipment, the following conditions must be met: it should be installed indoors or in a relatively enclosed environment, and in the central area of ​​the indoor or sealed environment to maximize its circulation sterilization range. After starting the drive motor 6, the turbine fan blades 15 can be made to rotate rapidly by controlling the speed of the drive motor 6. The air located outside the vertical hollow shell 1 can enter the air sterilization chamber 2 through the filter of the annular filter screen 9. Due to its side design, it has a wide filtration range and sufficient air intake. The air entering the air sterilization chamber 2 will be irradiated by the high-energy UV beam tube 11 to achieve a sterilization effect, thereby sterilizing and disinfecting the flowing air.

[0021] To guide the flow of air and reduce turbulence caused by changes in airflow direction, please refer to [link / reference needed]. Figure 1 It is necessary to provide an upward conical boss structure 4 on the upper end surface of the support substrate 3, and the conical boss structure 4 is a conical structure that is narrow at the top and wide at the bottom, and the radius of the upper end surface structure of the conical boss structure 4 is smaller than the diameter of the gas discharge port 14.

[0022] To increase the gas flow rate and simultaneously direct the gas around the high-energy UV beam tube 11, please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4A rotating air inlet structure 12 is required, which is installed in the center of the air sterilization chamber 2. Inside the structure, there is an inclined fin 124 that rotates with the rotor 7 of the drive motor 6 and draws in the surrounding gas into the central area during rotation. The inclined fin 124 can rotate with the rotor 7. During rotation, since the direction pointed to by the extension of the inclined fin 124 is deviated from the axis of the driven shaft 121, the surrounding gas will accelerate and flow into the air sterilization chamber 2, thus initially accelerating the gas flow. At the same time, the gas will concentrate near the high-energy UV beam tube 11. Combined with the rotational driving capability of the turbine blade 15 installed on the rotor 7 of the drive motor 6, the gas can be initially directionally driven and also receive the acceleration function of the turbine blade 15, thereby effectively improving the diversity of gas driving. This diversity is in a series combination relationship, thereby increasing the gas flow speed and guiding the gas to the vicinity of the high-energy UV beam tube 11.

[0023] For details regarding the specific structure of the rotating air injection structure 12, please refer to [link / reference]. Figure 2 , Figure 3 and Figure 4 The system includes a driven shaft 121 that connects to the end of the rotor 7 of the drive motor 6. To achieve better sterilization, the axis of the high-energy UV beam tube 11 and the axis of the driven shaft 121 should be collinear. On the shaft of the driven shaft 121, a ring bracket 123 is installed near its two ends via a horizontal connecting rod 122. The two ring brackets 123 have multiple annular array-shaped oblique fins 124 welded to their opposite ends. To achieve maximum air filtration, the oblique fins 124 should be located in the inner region of the annular filter screen 9. There should be a gap between every two oblique fins 124 for gas flow. The area between the oblique fins 124 and the driven shaft 121 is located in the horizontal front direction of the air inlet of the gas outlet 14.

[0024] To increase the stability of the rotating air injection structure 12 during rotation, please refer to... Figure 1 and Figure 5Two rotating horizontal support structures 13 need to be set up. Each rotating horizontal support structure 13 includes a bottom annular support body 131 and a top annular support body 133. The outer circumferential surfaces of both the bottom annular support body 131 and the top annular support body 133 are provided with annular fixing plate structures 132 for fixed connection. The center of the bottom annular support body 131 and the top annular support body 133 is provided with annular hole structures 134. The bottom annular support body 131 and the top annular support body 133 are respectively provided with bottom annular holes on the symmetrical plane. The bottom annular groove 135 and the top annular groove 136 have the same structural shape and dimensions. To ensure the smoothness of the rotation process and the horizontal support capacity, the structural radius of the arc structure of the bottom annular groove 135 and the top annular groove 136 needs to be the same as the structural radius of the ball 137, and the depth of the bottom annular groove 135 and the top annular groove 136 is less than the structural radius of the ball 137. Multiple rolling balls 137 are installed between the 36 sections. The balls 137 are spaced apart by a retainer 138. One bottom annular support 131 is fixedly installed at the bottom of the air sterilization chamber 2. A matching top annular support 133 is fixedly installed on the bottom end face of the bottom annular bracket 123. Another bottom annular support 131 is fixedly installed on the top end face of the top annular bracket 123. A matching top annular support 133 is fixedly installed at the top of the air sterilization chamber 2. When the rotor 7 of the drive motor 6 drives the annular bracket 123 to rotate, the balls 137 can rotate inside the bottom annular groove 135 and the top annular groove 136. While rotating, the balls 137 can also provide necessary horizontal support. Since the rotation of the balls 137 is achieved through rolling friction, the wear caused by friction can be effectively reduced, and the effective service life of the equipment can be increased.

[0025] When in use, the device is placed indoors or in a relatively enclosed environment, in the center of the indoor or sealed environment. The drive motor 6 and the high-energy UV beam tube 11 are started. By controlling the speed of the drive motor 6, the turbine fan blades 15 can rotate rapidly. The air located outside the vertical hollow shell 1 can enter the air sterilization chamber 2 through the filter of the annular filter 9. The air entering the air sterilization chamber 2 will be irradiated by the high-energy UV beam tube 11 to achieve a sterilization effect, thereby sterilizing and disinfecting the flowing air. During this process, the inclined fin 124 rotates together with the rotor 7. During rotation, because the direction pointed to by the extension of the inclined fin 124 deviates from the axis of the driven shaft 121, the surrounding gas accelerates and flows towards the air sterilization chamber 2, thus initially accelerating the gas flow. Simultaneously, the gas concentrates near the high-energy UV beam tube 11. Combined with the rotational driving capability of the turbine blades 15 mounted on the rotor 7 of the drive motor 6, the gas is initially directionally driven while also receiving acceleration from the turbine blades 15, effectively improving the versatility of gas driving. The components are arranged in a series combination to increase the gas flow speed and guide the gas to the vicinity of the high-energy UV beam tube 11. At the same time, in order to ensure the stability of the equipment during rotation, the following layout is required: When the rotor 7 of the drive motor 6 drives the annular support 123 to rotate, the ball bearings 137 can rotate inside the bottom annular groove 135 and the top annular groove 136. While rotating, the ball bearings 137 can also provide necessary horizontal support. At the same time, since the rotation of the ball bearings 137 is carried out by relative rotation in the form of rolling friction, it can effectively reduce the wear caused by friction and increase the effective service life of the equipment.
