Description

Technical Field

[0001] This utility model relates to the field of exhaust treatment technology for port reach stackers, and in particular to an integrated exhaust treatment device for port reach stackers. Background Technology

[0002] In port operations, reach stackers, as important loading and unloading equipment, generate a large amount of exhaust gas during operation. If this exhaust gas is discharged directly without effective treatment, it will not only cause serious pollution to the surrounding environment of the port, affecting air quality and endangering the health of workers and nearby residents, but may also face relevant legal penalties for failing to meet environmental emission standards, thereby affecting the normal operation and development of the port.

[0003] Existing exhaust gas treatment devices, such as the one disclosed in authorization (announcement) number CN105134349B, improve exhaust gas treatment to some extent by using a mixing device, a distribution chamber, and an exhaust gas treatment module to distribute urea evenly on the mixing pipe wall using centrifugal force generated by swirling flow, increasing the urea evaporation area and improving the evaporation rate. The distribution chamber also improves the uniformity of urea droplet distribution and reduces the risk of urea crystallization. However, this technical solution still has many shortcomings in practical applications. Firstly, it is inconvenient to disassemble and assemble the treatment filter. As a key component for filtering impurities in exhaust gas, the treatment filter gradually becomes clogged over time, reducing its filtration efficiency and requiring timely replacement or cleaning. However, existing devices have complex structures, cumbersome disassembly and assembly processes, and consume a lot of time and manpower, affecting equipment maintenance efficiency. Secondly, existing devices are not convenient for recirculating exhaust gas. During exhaust gas treatment, there may be cases where the exhaust gas still does not meet standards after one treatment. If this type of exhaust gas cannot be treated again, the emitted exhaust gas will not meet environmental protection requirements, failing to effectively solve the exhaust gas pollution problem. Utility Model Content

[0004] The purpose of this invention is to provide an integrated exhaust gas treatment device for port reach stackers. In exhaust gas treatment, it utilizes real-time monitoring by an oxygen sensor and the coordinated operation of a return pump to establish a highly efficient exhaust gas recirculation treatment mechanism. This mechanism can repeatedly recirculate exhaust gas that fails to meet standards after a single treatment until it is released, fundamentally reducing pollution in the port's surrounding environment and building a solid defense for the ecological environment and public health. Regarding equipment maintenance, the sealing cover can be easily removed by loosening the mounting bolts, allowing for convenient disassembly and assembly of the treatment filter. This greatly simplifies the replacement or cleaning process, effectively improving equipment maintenance efficiency and reducing maintenance costs. Simultaneously, the device features carefully designed sealing components on both sides of the treatment filter, working in conjunction with the sealing gasket at the bottom of the sealing cover to form a comprehensive, multi-layered sealing system, ensuring no exhaust gas leakage and comprehensively guaranteeing the exhaust gas treatment effect and the stability of the device's operation.

[0005] To achieve the above objectives, the main technical solutions adopted by this utility model include: An integrated exhaust treatment device for a port reach crane includes: A treatment housing for venting of port front cranes, wherein a treatment filter for venting of port front cranes is detachably installed inside the treatment housing, and sealing components are installed inside the treatment housing and on both sides of the treatment filter.

[0006] The aforementioned integrated exhaust treatment device for port reach cranes includes an air inlet for exhaust gas from the port reach crane installed on one side of the treatment housing, and an exhaust pump installed on the other side of the treatment housing.

[0007] The aforementioned integrated exhaust treatment device for port front cranes includes a sealing cover installed on the top of the treatment housing for fixing the treatment filter screen, the sealing cover being fixedly installed on the top of the treatment housing by mounting bolts.

[0008] The aforementioned integrated exhaust treatment device for port front cranes includes a sealing gasket fixedly connected to the bottom of the sealing cover for sealing the treatment filter.

[0009] The aforementioned integrated exhaust treatment device for port reach cranes includes a return pump for exhaust return treatment installed at the bottom of the treatment housing. One side of the return pump is connected to the treatment housing via a return pipe, and the other side of the return pump is connected to the treatment housing via a suction pipe. The return pipe and the suction pipe are respectively placed on both sides of the treatment filter.

[0010] The aforementioned integrated exhaust treatment device for port reach stackers includes an oxygen sensor installed on the top of the treatment housing and on the side near the exhaust pump, and the oxygen sensor is electrically connected to the return pump and the exhaust pump via a vehicle-mounted system.

[0011] The aforementioned integrated exhaust treatment device for port reach cranes includes a sealing assembly comprising a mounting ring fixedly connected to the inner wall of the treatment housing, the mounting ring having an annular sealing groove, an abutment spring fixedly connected to the inner wall of the annular sealing groove, a sealing ring matching the annular sealing groove fixedly connected to the other end of the abutment spring, and a sealing ring fixedly connected to the side of the sealing ring.

[0012] This utility model has at least the following beneficial effects: 1. In the present utility model, an integrated exhaust gas treatment device for a port reach stacker is implemented. In terms of exhaust gas treatment, with the coordinated operation of the oxygen sensor for real-time monitoring and the return pump, an efficient exhaust gas circulation treatment mechanism is established, which can perform multiple cycles of treatment on exhaust gas that fails to meet the standards after primary treatment, and discharge it only until it meets the environmental protection standards, fundamentally reducing pollution to the surrounding environment of the port and building a solid line of defense for the ecological environment and personnel health. In terms of equipment maintenance, the sealing cover can be easily removed by loosening the mounting bolts on the sealing cover, so as to realize convenient disassembly and assembly of the treatment filter screen, greatly simplifying the replacement or cleaning process, effectively improving the equipment maintenance efficiency and reducing the maintenance cost. Meanwhile, sealing assemblies are carefully arranged on both sides of the treatment filter screen in the device, which cooperate with the sealing gasket at the bottom of the sealing cover to form an all-round and multi-level sealing system, ensuring no leakage of exhaust gas, and fully guaranteeing the exhaust gas treatment effect and the operation stability of the device.

[0013] 2. In the present utility model, exhaust gas is introduced into the treatment housing through the air inlet, and after being treated by the treatment filter screen, it is discharged to the side of the treatment filter screen. At this time, the oxygen sensor monitors the treated exhaust gas in real time and transmits the monitoring data to the vehicle control system in real time. When the exhaust gas is monitored to be qualified, it is discharged through the exhaust pump; when it is monitored to be unqualified, the return pump is started to pump the exhaust gas back to the front section of the treatment filter screen for re-treatment. After the treatment is completed, the exhaust gas is monitored by the oxygen sensor again, and the process is repeated in this way until the exhaust gas is monitored to be qualified and then discharged. This cyclic treatment method ensures that the discharged exhaust gas meets the environmental protection standards, effectively reduces pollution to the surrounding environment of the port, and protects the ecological environment and personnel health.

During the placing process, both sides of the treatment filter screen will squeeze the sealing ring, so that the sealing gasket on the side of the sealing ring slides on the inner wall of the annular sealing groove and compresses the abutting spring. Under the abutting action of the abutting spring, the sealing ring is in close abutment with the side face of the treatment filter screen, achieving a good sealing effect. Finally, the sealing gasket at the bottom of the sealing cover is hermetically installed above the treatment filter screen, and the sealing cover is installed and fixed by the mounting bolts, so that the sealed installation of the treatment filter screen can be completed. The entire disassembly and assembly process is simple and easy to operate, which greatly improves the equipment maintenance efficiency and reduces the maintenance cost.

[0018] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0019] Please refer to Figures 1 to 4As shown, this utility model provides an integrated exhaust treatment device for port reach stackers, designed to efficiently treat exhaust gases generated during the operation of port reach stackers, meet environmental protection requirements, and ensure a clean and safe port operating environment. It mainly includes a treatment housing 1 for treating exhaust gases from the port reach stackers. A treatment filter 2 for treating exhaust gases from the port reach stackers is detachably installed inside the treatment housing 1, and sealing components 3 are installed on both sides of the treatment filter 2.

[0020] To ensure the smooth entry and compliant emission of exhaust gas from the port reach crane, in this embodiment: an air inlet 101 for the exhaust gas from the port reach crane is installed on one side of the treatment housing 1, and an exhaust pump 1011 is installed on the other side. The air inlet 101 guides the exhaust gas generated by the port reach crane accurately into the treatment housing 1, while the exhaust pump 1011 provides power to discharge the exhaust gas outside the device after it has been treated to meet the standards. The reasonable arrangement of the air inlet 101 and the exhaust pump 1011 ensures smooth flow of exhaust gas within the device, allowing the exhaust gas to enter the treatment stage according to a predetermined path and be finally discharged, which is the basic guarantee for realizing the exhaust gas treatment function.

[0021] To facilitate the fixing and disassembly of the processing filter 2 for subsequent maintenance and replacement, in this embodiment, a sealing cover 201 for fixing the processing filter 2 is installed on the top of the processing housing 1. The sealing cover 201 is fixedly installed on the top of the processing housing 1 by mounting bolts 2011. When it is necessary to process or replace the processing filter 2, simply loosen the mounting bolts 2011 and remove the sealing cover 201 to operate on the processing filter 2. This design of the sealing cover 201 and the mounting bolts 2011 makes fixing and disassembling the processing filter 2 simple and quick, greatly improving the maintenance efficiency of the equipment and reducing maintenance costs.

[0022] To further enhance the sealing performance above the treatment filter 2 and prevent exhaust gas leakage, in this embodiment, a sealing gasket 202 for sealing the treatment filter 2 is fixedly connected to the bottom of the sealing cover 201. After the sealing cover 201 is installed and fixed, the sealing gasket 202 will tightly adhere to the top of the treatment filter 2, forming an effective sealing barrier. The sealing gasket 202 effectively prevents exhaust gas from leaking from above the treatment filter 2, ensuring that all exhaust gas can be filtered by the treatment filter 2, thus improving the exhaust gas treatment effect.

[0023] To achieve the recirculation treatment of non-compliant exhaust gases and ensure that the emitted exhaust gases meet environmental standards, in this embodiment: a recirculation pump 203 for exhaust gas recirculation treatment is installed at the bottom of the treatment housing 1. One side of the recirculation pump 203 is connected to the treatment housing 1 through a recirculation pipe 2032, and the other side is connected to the treatment housing 1 through a suction pipe 2031. The recirculation pipe 2032 and the suction pipe 2031 are respectively placed on both sides of the treatment filter 2. When non-compliant exhaust gases are detected, the recirculation pump 203 starts, extracts the non-compliant exhaust gases through the suction pipe 2031, and then sends the exhaust gases back to the front of the treatment filter 2 through the recirculation pipe 2032 for reprocessing. The recirculation treatment structure composed of the recirculation pump 203, the recirculation pipe 2032, and the suction pipe 2031 can recirculate and treat non-compliant exhaust gases, improving the thoroughness of exhaust gas treatment and ensuring that the final emitted exhaust gases meet environmental requirements.

[0024] To monitor exhaust gas treatment in real time and intelligently control the operation of exhaust pump 1011 and return pump 203 based on the monitoring results, in this embodiment, an oxygen sensor 204 is installed on the top of the treatment housing 1, near the exhaust pump 1011. The oxygen sensor 204 is electrically connected to the return pump 203 and exhaust pump 1011 via the vehicle infotainment system. The oxygen sensor 204 can detect indicators such as oxygen content in the treated exhaust gas in real time and transmit the monitoring data to the vehicle infotainment system. The vehicle infotainment system determines whether the exhaust gas meets the standards according to preset standards, and then controls the operation of exhaust pump 1011 or return pump 203. The cooperation between the oxygen sensor 204 and the vehicle infotainment system realizes real-time monitoring and intelligent control of the exhaust gas treatment process, improves the automation and accuracy of exhaust gas treatment, and ensures that the device is always in optimal working condition.

[0025] To ensure the sealing effect on both sides of the filter screen 2 and prevent exhaust gas from leaking from both sides, in this embodiment: the sealing assembly 3 includes an installation ring 301 fixedly connected to the inner wall of the processing housing 1. The installation ring 301 has an annular sealing groove 3021. An abutment spring 303 is fixedly connected to the inner wall of the annular sealing groove 3021. The other end of the abutment spring 303 is fixedly connected to a sealing ring 302 that matches the annular sealing groove 3021. A sealing ring 3011 is fixedly connected to the side of the sealing ring 302. When the processing filter 2 is placed inside the processing housing 1, it will compress the sealing ring 3011. The structure on the side of the sealing ring 3011 will slide on the inner wall of the annular sealing groove 3021 and compress the abutment spring 303. Under the abutment action of the abutment spring 303, the sealing ring 3011 is tightly abutted against the side of the processing filter 2. This structural design of the sealing assembly 3, through the elastic action of the abutment spring 303, enables the sealing ring 3011 to always keep tightly fitted to the side of the processing filter 2, effectively preventing exhaust gas from leaking from both sides of the processing filter 2, and further improving the sealing performance of the device. It is worth noting that the oxygen sensor 204 of this utility model uses a sensor with model number 06B906265C.

[0026] The working principle of this utility model is as follows: The exhaust gas generated by the port reach crane is introduced into the treatment housing 1 through the air inlet 101. It is first filtered by the treatment filter 2, and the treated exhaust gas is discharged to the side of the treatment filter 2. At this time, the oxygen sensor 204 monitors the treated exhaust gas in real time and transmits the monitoring data to the vehicle control system in real time. The vehicle control system judges whether the exhaust gas meets the standard according to the preset standard. If the exhaust gas is found to be qualified, the exhaust pump 1011 is started to discharge the qualified exhaust gas outside the device. If the exhaust gas is found to be unqualified, the return pump 203 is started to extract the unqualified exhaust gas through the suction pipe 2031 and then send the exhaust gas back to the front of the treatment filter 2 through the return pipe 2032 for re-treatment. After the treatment is completed, the oxygen sensor 204 is monitored again. This process is repeated until the gas is qualified before it is discharged.

[0027] Meanwhile, when the processing filter 2 needs to be replaced, loosen the mounting bolts 2011 on the sealing cover 201, remove the sealing cover 201, and the processing filter 2 can be easily taken out. Place the new processing filter 2 back into the processing housing 1. During the placement process, the two sides of the processing filter 2 will squeeze the sealing ring 3011, causing the structure on the side of the sealing ring 3011 to slide on the inner wall of the annular sealing groove 3021 and compress the abutment spring 303. Under the abutment action of the abutment spring 303, the sealing ring 3011 is tightly abutted against the side of the processing filter 2. Finally, the sealing gasket 202 at the bottom of the sealing cover 201 is sealed and installed on top of the processing filter 2, and the sealing cover 201 is installed and fixed by the mounting bolts 2011 to achieve the sealed installation of the processing filter 2.
