Description

Technical Field

[0001] The utility model relates to the technical field related to fly ash treatment, and in particular to a chelating treatment device for incineration fly ash. Background Art

[0002] The basic principle of fly ash chelation process is to react fly ash with appropriate chelating agents to form stable chelates. Commonly used chelating agents include silicates, aluminates, etc.

[0003] When the fly ash is chelated, a related treatment device is used to mix the fly ash with a chelating agent, so that the fly ash and the chelating agent form a stable chelate. Although the related treatment device can chelate the fly ash, the chelating agent has a certain viscosity when mixed with the fly ash, and part of the chelating agent will cause the fly ash to stick to the stirring rod, which is relatively troublesome and time-consuming to clean. As a result, the progress of the fly ash chelation treatment will be delayed due to cleaning the stirring rod. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a chelating treatment device for incineration fly ash.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A chelating treatment device for incineration fly ash comprises a box body, the box body is rotatably connected to a screw rod via a bearing, a threaded sleeve is threadedly connected to the screw rod, a support rod is fixedly connected to the threaded sleeve, the support rod is rotatably connected to a stirring rod via a bearing, a scraper is attached to the outer wall of the stirring rod, and the scraper is fixedly connected to the inner wall of the box body.

[0007] Preferably, push rods are installed at one end and the other end of the box body, and bottom plates are fixedly connected to the output ends of the two groups of push rods, and the bottom plates are in contact with the bottom end of the box body.

[0008] Preferably, a first motor is mounted on the support rod, and an output end of the first motor is connected to the stirring rod.

[0009] Preferably, a second motor is installed on the box body, and an output end of the second motor is connected to the screw rod.

[0010] Preferably, a slide rail is fixedly connected to the box body, and the slide rail is slidably connected to the threaded sleeve.

[0011] Preferably, two sets of bases are fixedly connected to one end and the other end of the box.

[0012] Preferably, the size of the opening processed on the scraper is the same as the size of the stirring rod when viewed from above.

[0013] The beneficial effects of the utility model are:

[0014] 1. Through the coordination between the screw, threaded sleeve, support rod, stirring rod and scraper, when the stirring rod mixes the fly ash and chelating agent in the box, the screw is used to drive the threaded sleeve and the support rod to move upward, and the stirring rod is placed corresponding to the scraper and passes through the scraper. At this time, the scraper can hang the chelate on the part of the stirring rod that has been inserted into the box. The cleaning is relatively convenient and fast, and the time consumption is short, so the progress of the fly ash chelation treatment will not be delayed, and the working efficiency of the fly ash chelation treatment can be guaranteed;

[0015] 2. By cooperating between the push rods, the bottom plate and the box body, and using two sets of push rods to drive the bottom plate to move up and down, the bottom plate and the box body can be un-fitted or fitted, so that the chelate formed by the fly ash and the chelating agent can follow the downward movement of the bottom plate and be quickly moved out of the box body, making the collection of the chelate relatively convenient.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1, reference Figures 1 to 5A chelating treatment device for incineration fly ash comprises a box body 1, which is rotatably connected to a screw rod 2 through a bearing, and a threaded sleeve 3 is threadedly connected to the screw rod 2. The screw rod 2 can drive the threaded sleeve 3 to move vertically, and a support rod 4 is fixedly connected to the threaded sleeve 3. The threaded sleeve 3 can drive the support rod 4 to move vertically synchronously, and the support rod 4 is rotatably connected to a stirring rod 5 through a bearing. The stirring rod 5 is used to mix the fly ash and chelating agent pre-placed in the box body 1. A scraper 6 is attached to the outer wall of the stirring rod 5, and the scraper 6 is fixedly connected to the inner wall of the box body 1. The screw rod 2 is used to drive the support rod 4 to move upward, and the support rod 4 can drive the stirring rod 5 to move upward at the scraper 6. When the stirring rod 5 is placed corresponding to the scraper 6, the scraper 6 will clean and scrape off the chelate adhered to the stirring rod 5, and the cleaning is relatively convenient and time-saving.

[0024] In this embodiment, push rods 7 are installed at one end and the other end of the box body 1, and a bottom plate 8 is fixedly connected to the output ends of the two sets of push rods 7. The push rods 7 drive the lifting and movement of the bottom plate 8, and the bottom plate 8 can drive the chelate mixed with fly ash and chelating agent in the box body 1 to move out. The bottom plate 8 is in contact with the bottom end of the box body 1. A first motor 9 is installed on the support rod 4. The model of the first motor 9 is selected according to actual work requirements. The output end of the first motor 9 is connected to the stirring rod 5, and the first motor 9 can drive the stirring rod 5 to rotate. A second motor 10 is installed on the box body 1. The model of the second motor 10 is selected according to actual work requirements. The output end of the second motor 10 is connected to the screw 2, and the second motor 10 can drive the screw 2 to rotate. A slide rail 11 is fixedly connected to the box body 1, and the slide rail 11 is slidably connected to the threaded sleeve 3. The slide rail 11 can guide the lifting and movement of the threaded sleeve 3, thereby improving the lifting and movement stability of the screw 2 driving the threaded sleeve 3 and the support rod 4. Two groups of bases 12 are fixedly connected to one end and the other end of the box body 1. The size of the opening processed at the scraper 6 is the same as the top view size of the stirring rod 5, so that the stirring rod 5 can pass through the scraper 6, and the chelate adhering to the outer wall of the stirring rod 5 will also be stably cleaned and scraped off by the scraper 6.

[0025] The working principle of this embodiment is as follows: when in use, fly ash and chelating agent are poured into the housing 1 in batches, and at the same time, the first motor 9 is connected to an external power supply to drive the stirring rod 5 to rotate, and the stirring rod 5 will mix the chelating agent and the fly ash, and then mix the two into a chelate. After the mixing process is completed, the second motor 10 is connected to an external power supply to drive the screw 2 to rotate, and the screw 2 will drive the threaded sleeve 3, the support rod 4 and the stirring rod 5 to move upward. When the stirring rod 5 is placed corresponding to the scraper 6, it will pass through the scraper 6. At this time, the scraper 6 will clean the stirring rod 5 that is constantly moving upward, and the chelate adhered to the stirring rod 5 will be dropped. After the cleaning of the stirring rod 5 is completed, the two sets of push rods 7 drive the bottom plate 8 to move downward, and the bottom plate 8 will cancel the fit with the housing 1, and drive the chelate to move down out of the housing 1. At this time, the chelate mixed with the fly ash and the chelating agent is collected, and the chelating process of the fly ash is completed.
