Description

Technical Field

[0001] The utility model relates to the technical field of zipper machines, in particular to an anti-backdust discharging device for a zipper machine. Background Art

[0002] In current cement production, most of the cement clinker conveying equipment uses plate zipper conveyors (hereinafter referred to as zipper machines). Because there are certain gaps between the chain plates and the casing of the zipper machine, when the zipper machine conveys materials, the phenomenon of material leakage to the bottom of the casing often occurs, and a part of the clinker will also adhere to the chain plates. As the chain plates rotate to the lower part of the partition plate, plus the vibration of the equipment, this part of the adhered clinker will also fall to the bottom of the casing. Finally, under the push of the chain plates of the zipper machine, these clinkers will return to the kiln as backdust. A large amount of backdust entering the kiln, firstly, the backdust has high temperature, causing large fluctuations in the temperature of the preheater system and affecting the thermal stability of the cement kiln; secondly, this part of the backdust wastes the productivity of the zipper machine, causing duplication of workload and reducing production efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide an anti-backdust discharging device for a zipper machine to solve the problems that the backdust of the zipper machine affects the production quality of clinker and reduces the production efficiency of the zipper machine.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] An anti-backdust discharging device for a zipper machine includes a zipper machine body. A plurality of uniformly arranged chain plates are installed between two zippers of the zipper machine body. The casing of the zipper machine body is communicated with a chute below it. A scraping mechanism adapted to the chain plates is arranged in the chute. The scraping mechanism includes a swing rod, a scraping plate and a limiting plate. One end of the swing rod is rotatably connected to the chute through a torsion spring. The scraping plate is installed at the other end of the swing rod. The limiting plate is installed on the inner wall of the chute. The limiting plate abuts against the swing rod. The scraping plate is close to the partition plate of the zipper machine body.

[0006] A further technical solution is that the distance between two adjacent chain plates is greater than the maximum movement distance of the scraping plate in the horizontal direction.

[0007] A further technical solution is that a temporary storage bin is arranged at the upper part of the chute.

[0008] A further technical solution is that an electric gate valve is installed at the bottom of the chute.

[0009] A further technical solution is that a rubber pad is arranged on the side surface of the limiting plate facing the swing rod.

[0010] A further technical solution is that the head of the scraping plate is set to be conical.

[0011] A further technical solution is that the scraping mechanism is close to the discharge end of the zipper machine body.

[0012] Compared with the prior art, at least one of the following beneficial effects can be achieved by the present utility model:

[0013] The present utility model provides an anti-backdust discharging device for a zipper machine. The anti-backdust discharging device is arranged at the bottom of the zipper machine. When the chain plate returns dust, the returned dust will automatically fall into the chute. Moreover, the dust adhering to the chain plate will be blocked by the scraping mechanism and also fall into the chute, preventing the backdust from re-entering the kiln along with the zipper machine, ensuring the normal working condition in the cement kiln, and effectively improving the working efficiency of the zipper machine.

[0025] Embodiment 1:

[0026] This embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, an anti-backdust discharging device for a zipper machine includes a zipper machine body 1. A plurality of evenly distributed chain plates 3 are installed between two zippers 2 of the zipper machine body 1. The housing 4 of the zipper machine body 1 is communicated with a chute 5 below it. A scraping mechanism 6 adapted to the chain plates 3 is arranged in the chute 5. The scraping mechanism 6 includes a swing rod 7, a scraping plate 8 and a limiting plate 9. One end of the swing rod 7 is rotatably connected to the chute 5 through a torsion spring. The scraping plate 8 is installed at the other end of the swing rod 7. The limiting plate 9 is installed on the inner wall of the chute 5. The limiting plate 9 abuts against the swing rod 7. The scraping plate 8 is close to the partition plate 10 of the zipper machine body 1.

[0027] The chute 5 is located at the bottom of the zipper machine body 1. When the backdust leaking at the bottom of the housing 4 of the zipper machine body 1 moves back with the chain plates 3, it will fall into the chute 5. At the same time, in order to improve the backdust discharging effect, the swing rod 7 of the scraping mechanism 6 makes the scraping plate 8 tightly abut against the working surface of the moving chain plates 3 under the action of the torsion spring to form a scraping effect, and scrapes the materials adhered to the chain plates 3 into the chute 5. After the current chain plate 3 passes over the scraping plate 8, the swing rod 7 resets and is abutted by the limiting plate 9, waiting for the scraping work of the next chain plate 3. As the zipper machine works, the scraping plate 8 is cleaned repeatedly. This device ensures the normal working condition in the cement kiln and effectively improves the working efficiency of the zipper machine.

[0028] Preferably, the distance between two adjacent chain plates 3 is greater than the maximum movement distance of the scraping plate 8 in the horizontal direction.

[0029] Ensure that all the chain plates 3 can be thoroughly scraped by the scraping plate 8.

[0030] Preferably, a temporary storage bin 11 is arranged at the upper part of the chute 5.

[0031] When producing clinkers of different grades, sometimes the materials in the chute 5 are not cleaned up. At this time, the temporary storage bin 11 can be used to temporarily store the clinkers of different grades of cement being produced, preventing the backdust of the two clinkers from being mixed and resulting in non-recyclability.

[0032] Preferably, an electric gate valve 12 is installed at the bottom of the chute 5.

[0033] The electric gate valve 12 can be automatically started and closed through a PLC controller, blocking or connecting the feeding of the chute 5 and cooperating with the use of the temporary storage bin 11.

[0034] Preferably, a rubber pad 13 is arranged on the side surface of the limiting plate 9 facing the swing rod 7.

[0035] It plays a role in buffering and noise reduction.

[0036] Preferably, the head of the scraping plate 8 is set to be conical.

[0037] The conical shape reduces the contact surface, preventing excessive frictional force and rapid wear of the chain plate 3 and the scraper 8, and is also conducive to the smooth progress of the work between the two.

[0038] Preferably, the scraping mechanism 6 is close to the discharge end of the zipper machine body 1.

[0039] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
