Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production, in particular to a cyclone dust removal device for compound fertilizer production. Background Art

[0002] When producing compound fertilizer, various elements need to be mixed together, including high content of nitrogen, phosphorus, potassium, and low content of synergists. Various raw materials need to go through steps such as weighing, conveying, mixing, stirring, granulation, and packaging to finally form granular products. Since various raw materials of compound fertilizer are fine powder, there is no dust removal equipment in the existing workshop. During the production process, especially during the mixing, stirring, and granulation process, a large amount of dust will be generated at the work site, affecting the health of personnel and environmental safety.

[0003] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0004] The purpose of the utility model is to address the deficiencies of the prior art, thereby providing a cyclone dust removal device for compound fertilizer production, which can purify a compound fertilizer production workshop and recycle dust raw materials.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a cyclone dust removal device for compound fertilizer production, including a workshop and a plurality of cyclone dust collectors, a conveyor belt and a recovery silo arranged in the workshop, the plurality of cyclone dust collectors are arranged in a row, the air inlet of each cyclone dust collector is extended to the dust diffusion place of the compound fertilizer production equipment through an exhaust duct, and the clean air outlet of each cyclone dust collector is extended to the outside of the workshop through an air outlet duct; the conveyor belt passes through the bottom of the plurality of cyclone dust collectors in turn, and powder gathering inclined plates are provided on both sides of the conveyor belt directly below each of the discharge ports so as to gather the powder to the middle of the conveyor belt; the output end of the conveyor belt is connected to the feed port of the recovery silo.

[0006] Based on the above, a powder buffer plate is arranged under each discharge port, the top end of the powder buffer plate is hinged on the outer wall of the discharge port, and the bottom end of the powder buffer plate is inclined toward the conveying direction of the conveyor belt to play a buffering role on the powder.

[0007] Based on the above, when the powder buffer plate is completely opened, the bottom end of the powder buffer plate extends to the lower middle part of the powder collecting inclined plate.

[0008] Based on the above, three cyclone dust collectors are provided, and the three exhaust ducts are respectively extended to the dust diffusion places of the agitator, the mixer and the granulator.

[0009] Based on the above, the conveyor belt is a concave belt conveyor.

[0010] The utility model has substantial features and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0011] (1) The setting of multiple cyclone dust collectors corresponds to several equipment that mainly produce dust in the workshop. The exhaust duct sucks the produced dust into the cyclone dust collector. After dust removal, the clean air is discharged from the workshop through the air outlet duct, and the dust is discharged from the discharge port at the bottom of the cyclone dust collector and falls onto the conveyor belt. The powder gathering inclined plate gathers the powder towards the middle, which can prevent the powder from spilling out from both sides.

[0012] (2) The powder buffer plate is arranged on the falling path of the powder, which can block the powder and slow down the falling speed. Therefore, when it falls onto the conveyor belt, it is not easy to raise dust. When it is fully opened, the bottom end of the powder buffer plate extends to the middle and lower part of the powder gathering inclined plate, reducing the height difference with the surface of the conveyor belt, which can make the falling powder more stable.

[0013] (3) The conveyor belt adopts a concave belt conveyor, which always gathers the powder towards the middle and can prevent it from falling out from both sides during the transmission process. Description of the Drawings

[0017] The technical solution of the utility model will be further described in detail through specific embodiments below.

[0018] As Figure 1 and Figure 2 shown, a cyclone dust removal device for compound fertilizer production includes a workshop and three cyclone dust collectors 1, a conveyor belt 2, and a recycling bin 3 arranged in the workshop. The three cyclone dust collectors 1 are arranged in a row. The air inlet of each cyclone dust collector 1 is connected to an exhaust duct 4, the clean air outlet is connected to an air outlet duct 5, and a discharge port 6 is arranged at the bottom.

[0019] In the production of compound fertilizer, stirring, mixing and granulation are the steps with the most serious dust diffusion, so the three exhaust ducts 4 are respectively extended to the dust diffusion points of the stirrer, mixer and granulator to draw the dust into the cyclone dust collector 1, and the powder-containing air is settled and separated in the cyclone dust collector 1; the three air outlet ducts 5 are extended to the outside of the workshop to discharge the clean air to the outside; the conveyor belt 2 passes through the bottom of the three discharge ports 6 at the bottom of the cyclone dust collectors 1 in turn, and the settled powdered raw materials are discharged from the discharge port 6 and fall onto the conveyor belt 2.

[0020] In order to prevent the powder from spilling out from both sides, powder gathering inclined plates 7 are provided on both sides of the conveyor belt 2 directly below each of the discharge ports 6 so as to gather the powder to the middle of the conveyor belt 2; the output end of the conveyor belt 2 is connected to the feed port of the recovery silo 3. Specifically, the output end of the conveyor belt 2 can be directly extended into the interior of the recovery silo 3, thereby preventing dust from spreading during unloading.

[0021] In order to prevent the powdered raw materials from raising dust when falling onto the conveyor belt 2, a powder buffer plate 8 is provided below each of the discharge ports 6. The top of the powder buffer plate 8 is hinged on the outer wall of the discharge port 6, and the bottom of the powder buffer plate 8 is inclined toward the conveying direction of the conveyor belt 2, so as to play a buffering role for the powder. When the powder buffer plate 8 is fully opened, the bottom of the powder buffer plate 8 extends to the middle and lower part of the powder gathering inclined plate 8. When in use, the powder buffer plate 8 is located on the powder falling path, which can block the powder and slow down the falling speed. When fully opened, the bottom of the powder buffer plate 8 extends to the middle and lower part of the powder gathering inclined plate 7, reducing the height difference with the surface of the conveyor belt 2, so that the powder falling is more stable and not easy to raise dust.

[0022] In order to prevent the powder from falling out from both sides during the transmission process, the conveyor belt 2 adopts a concave belt conveyor to always gather the powder in the middle.

[0023] Working principle:

[0024] The three cyclone dust collectors 1 are arranged to correspond to the main dust-producing equipment in the workshop. The exhaust duct 4 sucks the produced dust into the cyclone dust collector 1. After sedimentation and separation, the clean air is discharged from the workshop through the outlet duct 4. The dust (recovered raw material) is discharged from the discharge port 6 at the bottom of the cyclone dust collector 1 and falls onto the conveyor belt 2. The powder gathering inclined plate 7 gathers the powder to the middle to prevent the powder from spilling from both sides. The powder buffer plate 8 buffers the powder to avoid raising dust. Finally, the conveyor belt 2 transports the recovered powdered raw materials to the recovery silo 3 for storage.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that it is still possible to modify the specific implementation manners of the present invention or perform equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
