A screening device for bio-organic fertilizer

Abstract

This utility model relates to the field of bio-organic fertilizer technology and discloses a screening device for bio-organic fertilizer, including a shell, a filter assembly in the middle of the shell, and a discharge port at the bottom of the shell. The screening device for bio-organic fertilizer of this utility model uses an auger to push organic fertilizer to the left and a turning plate to turn the organic fertilizer, thereby screening it through a screening cylinder. Because the screening cylinder is tilted and higher on the left than the right, the bio-organic fertilizer stays inside the screening cylinder for a longer time, improving the screening effect. An air pump compresses air filtered by an air filter and delivers it into the output pipe through a three-way pipe, finally spraying it out from a nozzle to backflush the rotating screening cylinder, thereby blowing out organic fertilizer stuck in the screening cylinder holes. Cleaning brushes clean the outside of the screening cylinder to prevent the screen holes from becoming clogged, improving production efficiency.

Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer technology, and in particular to a screening device for bio-organic fertilizer. Background Technology

[0002] Bio-organic fertilizer is a type of fertilizer made by fermenting organic matter such as agricultural waste and livestock manure with beneficial microorganisms. It combines the characteristics of organic fertilizer and microbial fertilizer and plays an important role in improving soil and enhancing crop quality. Screening is an important step in the production process of bio-organic fertilizer. Screening can separate fertilizer particles of different sizes to meet different usage needs.

[0003] Most existing bio-organic fertilizer screening devices use screening cylinders for screening. However, due to the complex composition of bio-organic fertilizers, the screening holes of the screening cylinder are easily blocked by fertilizer particles during the screening process. This not only reduces screening efficiency but also affects screening quality, requiring frequent shutdowns for cleaning, which increases production costs and labor intensity. Utility Model Content

[0004] The main objective of this invention is to provide a screening device for bio-organic fertilizers, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a screening device for biological organic fertilizer, including a shell, a filter assembly in the middle of the shell, a discharge port in the lower part of the shell, a back-blowing mechanism in the upper part of the shell, and a feed inlet in the right side of the shell;

[0006] The filter assembly includes a screening cylinder, a geared motor, a first pulley, a belt, and a second pulley. The left and right ends of the screening cylinder are rotatably connected to the middle of the left and right sides of the outer casing. The middle of the second pulley is fixedly connected to the right side of the screening cylinder. The middle of the first pulley is fixedly connected to the right output end of the geared motor. The lower part of the geared motor is located on the upper right side of the outer casing. The upper part of the belt is engaged with the outer circumference of the first pulley, and the lower part of the belt is engaged with the outer circumference of the second pulley.

[0007] Preferably, the inner wall of the screening cylinder is provided with an auger, and the tipping plates are fixedly connected to the inner wall of the screening cylinder at equal intervals, and the auger and the tipping plates are fixed to each other.

[0008] Preferably, the outer casing is tilted at 10° to 15°, with the left side higher than the right.

[0009] Preferably, a cleaning brush strip is provided in the middle of the inner top wall of the outer casing.

[0010] Preferably, the backflush mechanism includes an air pump, a three-way pipe, an output pipe, and nozzles. Multiple nozzles are installed at the lower part of the output pipe. The output pipe is located on the front and rear sides of the inner top wall of the housing. The lower part of the air pump is installed on the inner top wall of the housing. The output end of the air pump is connected to the output pipe through the three-way pipe.

[0011] Preferably, the air pump input end is provided with an air filter.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Add bio-organic fertilizer into the screening cylinder through the feed inlet, drive the reduction motor, so that pulley one drives pulley two to rotate through the belt, thereby causing the screening cylinder to rotate. The auger pushes the organic fertilizer to the left and the tipping plate turns the organic fertilizer over, thus screening the organic fertilizer through the screening cylinder. Because the screening cylinder is tilted and the left side is higher than the right side, the bio-organic fertilizer stays in the screening cylinder for a longer time, improving the screening effect of the organic fertilizer.

[0014] 2. Drive the air pump to compress the air filtered by the air filter and deliver it into the output pipe through the three-way pipe. Finally, it is sprayed out from the nozzle to backflush the rotating screening cylinder, thereby blowing out the organic fertilizer stuck in the holes of the screening cylinder. The cleaning brush strip cleans the outside of the screening cylinder to prevent the screen holes from being blocked and improve production efficiency. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-4 As shown, a screening device for biological organic fertilizer includes a shell 1, a filter assembly 3 in the middle of the shell 1, a discharge port 4 at the bottom of the shell 1, a backflushing mechanism 5 on the upper side inside the shell 1, and a feed inlet 2 on the right side of the shell 1.

[0022] In this embodiment, the filter assembly 3 includes a screening cylinder 301, a reduction motor 302, a first pulley 303, a belt 304, and a second pulley 305. The left and right ends of the screening cylinder 301 are rotatably connected to the middle of the left and right sides of the outer casing 1. The middle of the second pulley 305 is fixedly connected to the right side of the screening cylinder 301. The middle of the first pulley 303 is fixedly connected to the right output end of the reduction motor 302. The lower part of the reduction motor 302 is located on the upper right side of the outer casing 1. The upper part of the belt 304 is meshed with the outer periphery of the first pulley 303, and the lower part of the belt 304 is meshed with the outer periphery of the second pulley 305. An auger 306 is provided on the inner wall of the screening cylinder 301. Tilting plates 307 are fixedly connected to the inner wall of the screening cylinder 301 at equal intervals. The auger 306 and the tilting plates 307 are fixed to each other. The outer casing 1 is tilted at 10° to 15°, with the left side of the outer casing 1 higher than the right side.

[0023] Specifically, bio-organic fertilizer is added into the screening cylinder 301 through the feed inlet 2, driving the reduction motor 302, which causes pulley 1 303 to rotate through belt 304, thereby causing the screening cylinder 301 to rotate. The auger 306 pushes the organic fertilizer to the left, and the turning plate 307 turns the organic fertilizer over, thus screening the organic fertilizer through the screening cylinder 301. Because the screening cylinder 301 is tilted and the left side is higher than the right side, the bio-organic fertilizer stays in the screening cylinder 301 for a longer time, improving the screening effect of the organic fertilizer.

[0024] In this embodiment, a cleaning brush strip 6 is provided in the middle of the inner top wall of the outer casing 1. The back-blowing mechanism 5 includes an air pump 501, a three-way pipe 502, an output pipe 503, and a nozzle 504. Multiple nozzles 504 are installed at the lower part of the output pipe 503. The output pipe 503 is located on the front and rear sides of the inner top wall of the outer casing 1. The lower part of the air pump 501 is installed on the inner top wall of the outer casing 1. The output end of the air pump 501 is connected to the output pipe 503 through the three-way pipe 502. An air filter 505 is provided at the input end of the air pump 501.

[0025] Specifically, the drive air pump 501 compresses the air filtered by the air filter 505 and delivers it into the output pipe 503 through the three-way pipe 502. Finally, it is sprayed out from the nozzle 504, thereby back-blowing the rotating screening cylinder 301 and blowing out the organic fertilizer stuck in the holes of the screening cylinder 301. The cleaning brush strip 6 cleans the outside of the screening cylinder 301 to prevent the screen holes of the screening cylinder 301 from being blocked and improve production efficiency.

[0026] Working principle:

[0027] Bio-organic fertilizer is added into the screening cylinder 301 through the feed inlet 2. The drive motor 302 causes pulley 303 to rotate via belt 304, which in turn rotates pulley 305, causing the screening cylinder 301 to rotate. This, in turn, pushes the organic fertilizer to the left via auger 306 and turns it over via tilting plate 307, allowing it to be screened through the screening cylinder 301. Because the screening cylinder 301 is tilted and higher on the left than on the right, the bio-organic fertilizer accumulates inside the screening cylinder 301. The longer residence time improves the screening effect of organic fertilizer. The air pump 501 compresses the air filtered by the air filter 505 and delivers it into the output pipe 503 through the three-way pipe 502. Finally, it is sprayed out from the nozzle 504, which back-blown the rotating screening cylinder 301, thereby blowing out the organic fertilizer stuck in the holes of the screening cylinder 301. The cleaning brush 6 cleans the outside of the screening cylinder 301 to prevent the screen holes of the screening cylinder 301 from being blocked, thus improving production efficiency.
