Description

Technical Field

[0001] This utility model relates to the field of activated carbon adsorption technology, specifically a weighing device for condensing and recovering activated carbon adsorption vapor. Background Technology

[0002] The activated carbon adsorption vapor condensation recovery device uses activated carbon adsorbent to first adsorb and concentrate organic waste gas. The purified waste gas is then discharged, and the concentrated organic matter is recovered by a condensation recovery device after thermal desorption. During thermal desorption, the equipment needs to be weighed by an experimental weighing device to observe whether the activated carbon adsorption vapor condensation recovery device is at adsorption saturation, so that the activated carbon adsorption vapor condensation recovery device can be desorbed in a timely manner.

The beneficial effect of this utility model is that by mounting a support base at one end of the outer wall of the adsorption recovery tank above a weighing sensor, the adsorption recovery tank is weighed using the weighing sensor.

[0004] Although the aforementioned patent can weigh the adsorption and recovery tank, when the weighing sensor malfunctions and needs to be repaired or replaced, removing any corner of the weighing sensor will cause the adsorption and recovery tank to tilt, making maintenance extremely inconvenient.

[0024] 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.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution:

[0026] A weighing device for activated carbon adsorption vapor condensation and recovery includes a base 1 with several vertical support legs 2 evenly fixedly connected to its top along the circumference, and a support base 3 fixedly connected between the tops of the support legs 2; an adsorption recovery tank 4 disposed directly above the top of the support base 3; a weighing mechanism is provided between the adsorption recovery tank 4 and the support base 3; the weighing mechanism includes several mounting seats 6 evenly fixedly connected to the upper end of the support base 3 along the circumference, and a weighing sensor 7 fixedly connected to the top of the mounting seat 6; the weighing sensor 7 detects... The support base 3 is in contact with the lower end face of the adsorption and recovery tank 4. A weighing controller 8 is fixedly connected to the outside of one side of the support base 3. The weighing controller 8 is electrically connected to the weighing sensor 7. A vertical guide rod 9 is fixedly connected at the bottom of the adsorption and recovery tank 4 and between several weighing sensors 7. A guide hole 10 matching the guide rod 9 is opened at the top of the support base 3. The lower end of the guide rod 9 extends into the guide hole 10 and slides up and down along its inner wall. A lifting groove 5 is opened through the middle of the support base 3. A lifting machine is installed inside the lifting groove 5. The lifting mechanism includes a lifting plate 11 disposed inside the lifting groove 5, and several sliding grooves 12 evenly opened along the circumferential direction on the inner wall of the lifting groove 5. Several sliders 13 that slide in cooperation with the sliding grooves 12 are evenly fixedly connected along the circumferential direction on the outer periphery of the lifting plate 11. Several electric push rods 14 are evenly fixedly connected along the circumferential direction on the top of the base 1. The output shaft of the electric push rods 14 is fixedly connected to the lower end face of the lifting plate 11. A synchronization controller 15 is fixedly connected to the outside of the support base 3 on the side away from the weighing controller 8. The device 15 is electrically connected to the electric push rod 14. The top of the adsorption recovery tank 4 is detachably connected to the tank cover 16 by bolts. The top center of the tank cover 16 is fixedly connected to the clean gas discharge pipe 17. The upper sides of the adsorption recovery tank 4 are respectively fixedly connected to the steam discharge pipe 18 and the steam input pipe 19. The lower side of the adsorption recovery tank 4 is fixedly connected to the desorption recovery pipe 20. The bottom center of the adsorption recovery tank 4 is fixedly connected to the waste gas input pipe 21. The center of the lifting plate 11 is provided with a movable hole 22 that matches the waste gas input pipe 21.

[0027] In this embodiment, by using the synchronous controller 15, electric push rod 14 and lifting plate 11 together, the adsorption and recovery tank 4 can be lifted smoothly during maintenance, so that it can be separated synchronously from all weighing sensors 7. This solves the problem of tank tilting caused by single-point disassembly and realizes safe and convenient maintenance of the weighing mechanism.

[0028] Furthermore, the radial limit of the adsorption and recovery tank 4 is achieved through the cooperation of the guide rod 9 and the guide hole 10, which makes the tank posture stable during adsorption and recovery operations and ensures the accuracy of weighing measurement. At the same time, the guide structure effectively prevents the tank from deflecting during the lifting and maintenance process.

[0029] Working principle: During routine adsorption and recovery operations, the lower end of the adsorption and recovery tank 4 is directly supported on the weighing sensor 7. The weighing sensor 7 detects the overall weight of the adsorption and recovery tank 4 in real time. Vapor enters the adsorption and recovery tank 4 through the vapor inlet pipe 19, where the organic components are adsorbed by the activated carbon. The purified gas is discharged through the clean gas outlet pipe 17, while auxiliary waste gas is introduced through the waste gas inlet pipe 21. During the adsorption process, the weighing sensor 7 continuously transmits weight signals to the weighing controller 8. By monitoring the increase in weight, the amount of recovered vapor after condensation can be calculated. When the activated carbon... After adsorption saturation, desorption steam is introduced through steam discharge pipe 18 for regeneration. The desorbed steam is discharged and recovered through desorption recovery pipe 20. At this time, the weight of adsorption recovery tank 4 gradually decreases, and the weighing sensor 7 continues to monitor the desorption process. Only when maintenance is required will the electric push rods 14 be activated by the synchronous controller 15 to extend synchronously, push the lifting plate 11 to rise and lift the adsorption recovery tank 4, so that it is out of contact with the weighing sensor 7 for maintenance operations. After maintenance is completed, the electric push rods 14 retract, the lifting plate 11 descends, and the adsorption recovery tank 4 is supported by the weighing sensor 7 again.

[0030] In the specific implementation of this technical solution, the weighing controller 8 can be configured with conventional signal processing units in the prior art (such as weighing transmitters, weight calculation instruments, or PLC weight modules). Although such weighing controllers are not described in detail in the technical solution, they are industrial control devices that can be conventionally selected by those skilled in the art based on actual weighing monitoring needs. Their signal acquisition, processing, and display functions follow well-known technologies in this field and do not affect the implementation of the core innovation of this solution. In practical applications, the weighing controller 8 is mainly used to process the signals from the weighing sensor 7 in real time and display the weight value of the adsorption recovery tank 4, but its specific type and connection method can be adjusted according to production requirements, all of which fall within the reasonable extension scope of this technical solution.

[0031] In the specific implementation of this technical solution, the synchronous controller 15 can be configured with conventional multi-axis motion controllers in the prior art (such as PLC synchronous control units, multi-channel motor synchronous drivers, or dedicated synchronous motion control cards). Although such synchronous controllers are not described in detail in the technical solution, they are control devices that can be conventionally selected by those skilled in the art based on actual multi-drive synchronous lifting requirements. Their synchronization logic and control algorithms follow well-known technologies in the field and do not affect the implementation of the core innovation of this solution. In practical applications, the synchronous controller 15 is mainly used to control the synchronous extension and retraction of each electric push rod 14 to improve the stability of the lifting plate 11, but its specific type and linkage method can be adjusted according to the equipment precision requirements, all of which fall within the reasonable extension range of this technical solution.

[0032] It should be noted that the adsorption recovery tank 4 described in this technical solution is existing technology. Its specific internal structure (such as the activated carbon bed, airflow distributor, etc.) and model can be conventionally selected and configured according to actual treatment needs. Those skilled in the art can make appropriate selections from commercially available or conventionally designed adsorption tanks based on specific process conditions (such as treatment air volume, steam composition, adsorption efficiency, etc.). The differences in the specific internal structure and model of the tank do not affect the implementation of the core innovation of this solution.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
