Description

TECHNICAL FIELD

[0001] The utility model belongs to urea ammonium nitrogen fertilizer preparation technical field, concretely relates to a kind of synergistic urea ammonium nitrogen fertilizer preparation drying device. BACKGROUND

[0002] Urea ammonium nitrogen fertilizer preparation is a kind of process that high-efficiency nitrogen fertilizer is generated by combining urea and ammonium salt (such as ammonium sulfate, ammonium chloride, etc.) through chemical reaction. Its main components include urea and ammonium nitrogen, with both quick-acting and slow-acting characteristics, which can provide crops with sustained and stable nitrogen nutrition. The preparation process usually includes raw material mixing, reaction, granulation, drying and other steps, among which the drying link is used to remove moisture in the fertilizer to ensure product stability. Urea ammonium nitrogen fertilizer has the advantages of high nutrient content, good solubility and high utilization rate, and is widely used in agricultural production, which can effectively promote crop growth and improve yield and quality. At the same time, its preparation process needs to pay attention to environmental protection to reduce the pollution of dust and waste to the environment.

[0028] The drying mechanism 100 comprises a drying box 101 for drying urea-ammonium nitrogen fertilizer, a discharge pipe 102 communicated with the surface of the drying box 101, a motor 103 fixedly installed at the top of the drying box 101, a rotating shaft 104 fixedly installed at the output end of the motor 103, a plurality of fixed frames 105 fixedly installed on the surface of the rotating shaft 104, and a plurality of mixing rods 106 fixedly installed on the inner side of the fixed frames 105.

[0029] The dust removal mechanism 200 comprises a dust removal component 201 for dust removal inside the drying box 101 and a cleaning component 202 for cleaning the inner wall of the drying box 101.

[0030] The dust removal component 201 is used for dust removal inside the drying box 101, which solves the problem of raw material dust generated during drying of urea-ammonium nitrogen fertilizer in the traditional drying device, avoids raw material waste and environmental pollution, and improves the dust removal effect; the cleaning component 202 is used for cleaning the inner wall of the drying box 101, which prevents wet fertilizer from adhering to the inner wall during the drying process and improves the utilization rate of urea-ammonium nitrogen fertilizer.

[0031] Specifically, the dust removal component 201 comprises a plurality of communication grooves opened at the top of the drying box 101, a rotating rod 201a rotatably installed in the communication grooves, dust removal fan blades 201b fixedly installed at the end of the rotating rod 201a, and a plurality of cylinder bodies 201c fixedly installed on the surface of the drying box 101 and sleeved around the dust removal fan blades 201b.

[0032] The inside of the cylinder body 201c is provided with a dust collection net, and the surface of the cylinder body 201c is also provided with a hollow groove matched with the driving gear 201d.

[0033] Further, the dust removal component 201 further comprises a driving gear 201d fixedly installed on the surface of the rotating shaft 104 and a driven gear 201e fixedly installed on the surface of the rotating rod 201a and engaged with the driving gear 201d.

[0034] Preferably, a plurality of air inlets are opened at the bottom of the drying box 101, and a filter screen is arranged in each air inlet.

[0035] The air inlets are used for guiding air into the inside of the drying box 101, and the air entering the inside of the drying box 101 is dusted under the action of the filter screen, so that the dust does not enter the inside of the drying box 101 and affects the drying effect of the urea-ammonium nitrogen fertilizer.

[0036] Further, the cleaning component 202 comprises a mounting strip 202a elastically mounted on the fixed frame 105, and a scraper 202b fixedly mounted on the surface of the mounting strip 202a and used for cleaning the inner wall of the drying box 101.

[0037] When the fixed frame 105 rotates, the mounting strip 202a is driven to rotate, the mounting strip 202a drives the scraper 202b to rotate and scrape off the urea ammonium nitrogen adhered to the inner wall of the drying box 101, so as to avoid the urea ammonium nitrogen from adhering to the inner wall of the drying box 101 and improve the utilization rate of the urea ammonium nitrogen.

[0038] Specifically, the cleaning component 202 further comprises two springs 202c fixedly mounted on the fixed frame 105 through a circular plate, and the end surface of the spring 202c is fixedly connected with the surface of the mounting strip 202a.

[0040] Further, the surface of the fixed frame 105 is provided with a mounting groove 202d used for limiting the mounting strip 202a, and the size of the mounting groove 202d is matched with that of the mounting strip 202a.

[0041] The mounting groove 202d is used for limiting the mounting strip 202a, further improves the stability of the scraper 202b, and further improves the cleaning effect of the scraper 202b on the inner wall of the drying box 101.

[0042] In use, the sealing plug at the top of the drying box 101 is removed, the urea ammonium nitrogen is introduced into the drying box 101 through the feeding port, and then the sealing plug is plugged at the feeding port.

[0043] The drying box 101 and the motor 103 are started, the urea ammonium nitrogen is dried by heating in the drying box 101, the rotating shaft 104 is driven to rotate under the action of the motor 103, the rotating shaft 104 drives the fixed frame 105 and the mixing rod 106 to rotate, and then the fixed frame 105 and the mixing rod 106 mix the urea ammonium nitrogen in the drying box 101.

[0044] When the rotating shaft 104 rotates, the rotating shaft 104 drives the driving gear 201d to rotate, the driving gear 201d drives the driven gears 201e to rotate, the driven gears 201e drive the dust removal fan blades 201b at the end thereof to rotate, the dust removal fan blades 201b rotate to discharge the air in the drying box 101, and the air is blown to the dust collection net through the cylinder 201c, and the dust collection net adsorbs and collects the dust.

[0045] At the same time, when the fixed frame 105 rotates, the installation strip 202a is driven to rotate, the installation strip 202a drives the scraper 202b to rotate and scrape off the urea-ammonium nitrogen fertilizer attached to the inner wall of the drying box 101.

[0046] In summary, the dust removal component 201 is used to remove dust in the drying box 101, which solves the problem of raw material dust generated during the drying of urea-ammonium nitrogen fertilizer in the traditional drying device, avoids raw material waste and environmental pollution, and improves the dust removal effect; the cleaning component 202 is used to clean the inner wall of the drying box 101, which prevents wet fertilizer from adhering to the inner wall during the drying process, and improves the utilization rate of urea-ammonium nitrogen fertilizer.
