Description

Technical Field

[0001] This utility model relates to the technical field of gypsum buffer box distribution and feeding device in flue gas desulfurization system, and particularly to gypsum buffer box distribution and feeding device in flue gas desulfurization system. Background Technology

[0002] In the process of flue gas desulfurization in thermal power plants, the gypsum buffer tank distribution and feeding device is an important piece of equipment used in the flue gas desulfurization system to distribute and feed the gypsum produced during the desulfurization process.

[0003] In the prior art, such as the Chinese patent CN217893884U entitled "A Flue Gas Desulfurization Lime Feeding Bin Device," a lime feeding bin body is included. A level gauge is installed on one side wall of the lime feeding bin body, a vibration motor is fixedly installed on one side wall, an observation window is embedded in the front side wall of the lime feeding bin body, and a feeding pipe is fixedly connected to the bottom of the lime feeding bin body. A connecting plate is fixedly installed on one side wall of the feeding pipe. This flue gas desulfurization lime feeding bin device uses a vibration motor to vibrate the lime feeding bin body, reducing the adhesion between the lime and the inner wall of the lime feeding bin body. The motor drives a rotating shaft to vibrate, which in turn drives a breaking rod to rotate, thereby stirring the inside of the lime feeding bin body and making the lime feeding smoother. Simultaneously, the friction between the breaking rod and the lime generates heat, reducing air humidity and preventing the lime from becoming damp. The lime feeding is controlled by pushing a manual insert plate to slide within a sliding sleeve and the feeding pipe.

[0004] Although this type of equipment can reduce the adhesion between lime and the inner wall of the lime feeding hopper by vibrating the lime feeding hopper body through a vibrating motor, some wet gypsum will still remain during the vibration cleaning process of wet gypsum in thermal power plants. This will cause the wet gypsum inside the machine to solidify and clump due to the long-term presence of wet gypsum residue on the inner wall of the funnel, affecting the normal operation of the equipment. Furthermore, it is very easy for the staff to damage the inside of the funnel when cleaning the gypsum clumps later. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the existing technology of the gypsum buffer box distribution and feeding device in the flue gas desulfurization system of thermal power plant does not have the ability to thoroughly clean the wet gypsum remaining on the inner wall of the device body. As a result, the wet gypsum remains inside the device body for a long time and cannot be cleaned in time, which causes the wet gypsum to solidify and clump, affecting the normal operation of the equipment. Later cleaning of the gypsum clumps can easily damage the equipment. Therefore, the proposed gypsum buffer box distribution and feeding device for flue gas desulfurization system is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a gypsum buffer tank dispensing device for a flue gas desulfurization system, comprising a base, a guide block fixedly installed on the top surface of the base, a support column fixedly installed on the top surface of the base, a motor A fixedly installed inside the base, a rotating shaft installed at the output end of the motor A, a rotating rod fixedly installed on the top surface of the rotating shaft, a buffer tank fixedly installed on the top surface of the support column, a funnel fixedly installed on the bottom surface of the buffer tank, a stirring rod A fixedly installed on the surface of the rotating rod, a stirring rod B fixedly installed on the surface of the rotating rod, a spring installed inside the stirring rod A, a top block slidably connected inside the stirring rod A, and a scraper fixedly installed at one end of the top block.

[0007] Preferably, a motor B is fixedly installed on one side of the buffer box, and sliding grooves are provided on both sides of the top surface of the buffer box. A bidirectional lead screw is installed at the output end of the motor B, and a limit block is fixedly installed on the middle surface of the bidirectional lead screw. A slider is slidably connected inside the sliding groove, and a limit rod is fixedly installed inside the sliding groove. A cover plate is fixedly installed on the surface of the slider, and a connecting flange is fixedly installed on the top surface of the cover plate.

[0008] Preferably, there are two sets of scrapers, which are symmetrically distributed at one end of the stirring rod A.

[0009] Preferably, the scraper and the funnel are slidably connected, and the material of the side of the scraper that is in contact with the funnel is natural rubber.

[0010] Preferably, one end of the spring is connected to the inside of the rotating rod, and the other end is connected to one end of the top block.

[0011] Preferably, there are two sets of cover plates, and the two sets of cover plates have a protrusion and a groove respectively on the side that they fit together, and the protrusion and the groove are slidably connected.

[0012] Preferably, the bidirectional lead screw is rotatably connected to the buffer box, the slider is threadedly connected to the bidirectional lead screw, and the slider is slidably connected to the slide groove.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the rotating shaft is driven to rotate by starting motor A. At this time, the rotating shaft will drive the rotating rod to rotate simultaneously. At the same time, the stirring rod A and stirring rod B, which are fixedly installed on the surface of the rotating shaft, will also rotate inside the funnel. This causes the top block inside the stirring rod to drive the scraper fixedly installed at one end of the top block to slide inside the funnel. This device effectively solves the problem that wet gypsum residue remains on the inner wall of the funnel during the feeding process, which causes the wet gypsum to solidify and clump, affecting the normal operation of the equipment. Furthermore, it is very easy for the staff to damage the inside of the funnel when cleaning the gypsum clumps later.

[0015] 2. In this utility model, the starting motor B drives the bidirectional lead screw to rotate in the slide groove. At this time, the slider will move simultaneously with the rotation of the bidirectional lead screw, thereby causing the cover plate and the connecting flange fixedly installed on the top surface of the slider to move. This device effectively solves the problems of inconvenience in opening the cover plate when the device is cleaned and maintained by the staff after the device has finished working, and inconvenience in opening the cover when multiple devices cannot be unloaded at the same time and when the staff buffer box is inspected and cleaned.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4As shown, this utility model provides a technical solution: a gypsum buffer tank 7 feeding device for a flue gas desulfurization system, including a base 1, a guide block 2 fixedly installed on the top surface of the base 1, a support column 3 fixedly installed on the top surface of the base 1, a motor A4 fixedly installed inside the base 1, a rotating shaft 5 installed at the output end of the motor A4, a rotating rod 6 fixedly installed on the top surface of the rotating shaft 5, a buffer tank 7 fixedly installed on the top surface of the support column 3, a funnel 8 fixedly installed on the bottom surface of the buffer tank 7, and a stirring rod A9 fixedly installed on the surface of the rotating rod 6. A stirring rod B10 is fixedly installed on the surface of the rotating rod 6. A spring 11 is installed inside the stirring rod A9. A top block 12 is slidably connected inside the stirring rod A9. A scraper 13 is fixedly installed at one end of the top block 12. There are two sets of scrapers 13, which are symmetrically distributed at one end of the stirring rod A9. The scrapers 13 are slidably connected to the funnel 8. The material of the side of the scraper 13 that is in contact with the funnel 8 is natural rubber. One end of the spring 11 is connected to the inside of the rotating rod 6, and the other end is connected to one end of the top block 12.

[0024] In this embodiment, the rotating shaft 5 is driven to rotate by starting the motor A4. At this time, the rotating shaft 5 will drive the rotating rod 6 to rotate simultaneously. At the same time, the stirring rod A9 and stirring rod B10, which are fixedly installed on the surface of the rotating shaft 5, will also rotate inside the funnel 8. The stress generated by the spring 11 installed inside the stirring rod A9 will push the top block 12 inside the stirring rod A9 to slide inside the stirring rod A9, so that the scraper 13 is attached to the inside of the funnel 8. This device effectively solves the problem that wet gypsum remains on the inner wall of the funnel 8 during the feeding process, which causes the wet gypsum to solidify and clump, affecting the normal operation of the equipment. Moreover, it is very easy for the staff to damage the inside of the funnel 8 when cleaning the gypsum clumps later.

[0025] Example 2: As Figures 1-4 As shown, a motor B14 is fixedly installed on one side of the buffer box 7. Slide grooves 15 are provided on both sides of the top surface of the buffer box 7. A bidirectional lead screw 16 is installed at the output end of the motor B14. A limit block 17 is fixedly installed on the middle surface of the bidirectional lead screw 16. A slider 18 is slidably connected inside the slide groove 15. A limit rod 19 is fixedly installed inside the slide groove 15. A cover plate 20 is fixedly installed on the surface of the slider 18. A connecting flange 21 is fixedly installed on the top surface of the cover plate 20. There are two sets of cover plates 20. The sides of the two sets of cover plates 20 that meet are respectively provided with a protrusion 22 and a groove 23. The protrusion 22 and the groove 23 are slidably connected. The bidirectional lead screw 16 is rotatably connected to the buffer box 7. The slider 18 is threadedly connected to the bidirectional lead screw 16. The slider 18 is slidably connected to the slide groove 15.

[0026] In this embodiment, the starting motor B14 drives the bidirectional lead screw 16 to rotate within the slide groove 15. At this time, the slider 18 will slide simultaneously within the slide groove 15 as the bidirectional lead screw 16 rotates, causing the slider 18, which is slidably connected to the surface of the limiting rod 19, to move along the slide groove 15. This causes the cover plate 20 fixedly installed on the top surface of the slider 18 and the connecting flange 21 fixedly installed on the top surface to move along the slide groove 15. This device effectively solves the problems of inconvenience in opening the cover plate 20 when the device is cleaned and repaired by the staff after the device has finished working, and inconvenience in opening the cover when multiple devices cannot be unloaded at the same time and when the staff buffer box 7 is inspected and cleaned.

[0027] The working principle of this embodiment is as follows: After the equipment to be discharged is connected to any connecting flange 21 through a pipe, the motor A4 is started to drive the rotating shaft 5 to rotate. At this time, the rotating shaft 5 will drive the rotating rod 6 to rotate simultaneously. At the same time, the stirring rod A9 and stirring rod B10, which are fixedly installed on the surface of the rotating shaft 5, will also rotate in the funnel 8. The stress generated by the spring 11 set inside the stirring rod A9 will push the top block 12 inside the stirring rod A9 to slide inside the stirring rod A9, so that the scraper 13 is attached to the inside of the funnel 8. At this time, the discharge work can begin. After the discharge is completed, when the equipment needs to be cleaned and inspected, the motor B14 is started to drive the bidirectional lead screw 16 to rotate in the slide groove 15. At this time, the slider 18 will slide simultaneously inside the slide groove 15 as the bidirectional lead screw 16 rotates, causing the slider 18 slidably connected to the surface of the limit rod 19 to slide. This causes the cover plate 20 fixedly installed on the top surface of the slider 18 and the connecting flange 21 fixedly installed on the top surface to move along the slide groove 15. At this time, the cover plate 20 is opened, and the staff can clean and inspect the buffer box 7.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
