Description

Rotary separation screen in an organic fertilizer screening device

technical field

The invention belongs to the technical field of organic fertilizer production, and in particular relates to a rotary separation screen in an organic fertilizer screening device.

Background technique

Organic fertilizer, commonly known as farmyard manure, refers to a slow-acting fertilizer containing a large amount of biological matter, animal and plant residues, excrement, biological waste and other substances. Organic fertilizer not only contains a large number of elements and trace elements necessary for plants, but also contains rich organic nutrients. , organic fertilizer is the most comprehensive fertilizer.

Organic fertilizers can be divided into solid fertilizers and liquid fertilizers according to their physical state. In the prior art, organic fertilizer manufacturers mostly use vibrating screens for screening when producing solid organic fertilizers; the working principle of vibrating screens is that the two motors are synchronously Reverse rotation causes the exciter to generate a reverse excitation force, forcing the screen body to drive the screen to move longitudinally, so that the materials on it are periodically thrown forward for a range by the excited vibration force, thereby completing the material screening operation; The existing vibrating screen has problems such as high power consumption, high noise, and high equipment cost due to high requirements for accessories. It is not suitable for manufacturers with weak production capacity. Organic fertilizer granules are screened thoroughly and are suitable for manufacturers with small annual production capacity.

Contents of the invention

The technical problem to be solved in the present invention is to provide a rotary separation sieve in an organic fertilizer screening device for the deficiencies of the existing organic fertilizer screening process, and to realize the collection of organic fertilizers of different particle sizes through the holes of different sieves; the whole The process screening effect is good, the rotation speed of the motor is small, the energy consumption is low, and the noise is also small. At the same time, the equipment is simple and the cost is low, which meets the production needs of the manufacturer.

In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions: a rotary separation screen in an organic fertilizer screening device, comprising a frame and a sieve device, the frame is cylindrical and wrapped around the periphery of the sieve device, the The sieve device is powered by a rotating device located at the geometric center; the circumference of the rotating device is formed by connecting sieves of three different meshes, and is in an inverted conical shape; partitions are arranged between adjacent sieves; the sieve device The lower part corresponds to a feeding channel in turn, and the bottom of the feeding channel is a collecting port.

Further, the height of the partition is half of the pore size of the corresponding separation sieve, ensuring that particles smaller than the pore size are retained and particles larger than the pore size are not blocked.

Further, the feed channel is between two baffles.

The working principle and beneficial effects of the present invention are as follows: when in use, the rotating device drives the sieve device to rotate, releasing the organic fertilizer from the middle of the top, the organic fertilizer particles diverge around and roll down, and the small particles are trapped in the middle by the inner partition , leaked from the hole of the small-hole separation sieve, passed through the small particle collection channel, and entered the small particle collection port to collect; the smaller particles passed through the inner partition and rolled down, but could not pass through the middle partition and were trapped in the middle hole On the separation sieve, it leaks from the holes of the sieve, passes through the smaller particle collection channel, and enters the smaller particle collection port; the larger particle is trapped on the large-pore separation sieve, and enters the larger particle collection port, and the large particle is not separated plate blocking, roll out of the separation sieve directly, and enter the large particle collection port; using this device, the organic fertilizer separation effect is good, and the separation of multi-size particles can be carried out. The motor rotation speed is small, the energy consumption is low, the noise is low, and the equipment is simple. The cost is low, which meets the production needs of manufacturers.

detailed description

Below in conjunction with accompanying drawing and embodiment the technical solution of the present invention is further described:

Frame 1, sieve device 2, rotating device 201, small hole separation sieve 202, medium hole separation sieve 203, large hole separation sieve 204, dividing plate 205, feed channel 3, small particle feed channel 301, smaller particle feed Material channel 302, larger particle feeding channel 303, large particle feeding channel 304, collecting port 4, small particle collecting port 401, smaller particle collecting port 402, larger particle collecting port 403, large particle collecting port 404.

As shown in Figures 1 and 2, a rotary separation screen in an organic fertilizer screening device includes a frame 1 and a sieve device 2, the frame 1 is cylindrical and wrapped around the periphery of the sieve device 2, so The sieve device 1 is powered by a rotating device 201 located at the geometric center. The periphery of the rotating device 201 is formed by connecting sieves of three different meshes, which are in the shape of an inverted cone, and there are small hole separating sieves 202 from the inside to the outside. , dividing plate 205, medium-pore separating sieve 203, dividing plate 205, large-pore separating sieve 204, dividing plate 205; The height of described dividing plate 204 is half of the aperture size of corresponding separating sieve, guarantees that the particle that is less than aperture is intercepted, and greater than Particles of the pore size are not blocked. The lower part of the sieve device 1 corresponds to a feed channel 3 in turn, and the feed channel 3 is located between two baffle plates, and from the inside to the outside is a small particle feed channel 301, a smaller particle feed channel 302, a relatively small particle feed channel 302, and a smaller particle feed channel 302. Large particle feed channel 303, large particle feed channel 304, the large particle channel 303 is between the frame and the outermost baffle plate; the bottom of the feed channel 3 is the collection port 4 corresponding to the collection port 4 Corresponding feed channel 3, from the inside to the outside, is successively a small particle collection port 401, a smaller particle collection port 402, a larger particle collection port 403, and a large particle collection port 404.

When in use, the rotating device 201 drives the sieve device 2 to rotate, releasing the organic fertilizer from the middle part of the top, the organic fertilizer particles diverge around and roll down, and the small particles are trapped in the middle part by the inner layer partition 205, and the separation screen 202 from the small holes The small particles leak down through the small particle collection channel 301 and enter the small particle collection port 401 for collection; the smaller particles pass through the inner layer partition 205 and roll down, but cannot pass through the middle layer partition 205 and are trapped in the middle hole separation screen 203, leaks from the hole of the sieve, passes through the smaller particle collection channel 302, and enters the smaller particle collection port 402; the larger particle is trapped on the large-pore separation sieve 2004, enters the larger particle collection port 403, and the larger particle Not blocked by the partition plate 205, directly roll out of the separation sieve and enter the large particle collection port 404.
