Description

Technical Field

[0001] This utility model belongs to the technical field of organic fertilizer processing equipment, specifically relating to a screening device for organic fertilizer. Background Technology

[0002] Organic fertilizer is a carbon-containing material primarily derived from plants and / or animals, applied to the soil to provide nutrients to plants. Processed from biological matter, animal and plant waste, and plant residues, it eliminates toxic and harmful substances and is rich in beneficial substances, including various organic acids, peptides, and abundant nutrients such as nitrogen, phosphorus, and potassium. It not only provides comprehensive nutrition for crops but also has a long-lasting effect, increasing and renewing soil organic matter, promoting microbial reproduction, and improving the soil's physical, chemical, and biological properties. It is a key nutrient source for green food production.

[0003] Organic fertilizer screening is a crucial step in the organic fertilizer production process, directly affecting the product's appearance, quality, application efficacy, and market value. The moisture content of the organic fertilizer is one of the key factors influencing screening efficiency. Too low a moisture content may lead to excessive crushing of the organic fertilizer, generating dust that pollutes the environment and harms workers' health. Too high a moisture content results in highly sticky organic fertilizer that easily clogs the screen, drastically reducing screening efficiency or even making screening impossible. Therefore, there is an urgent need to design an organic fertilizer screening device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a screening device for organic fertilizer to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screening device for organic fertilizer, comprising:

[0006] The screening mechanism includes a screen box, a vibrator fixed at one end of the screen box, and vibration damping springs fixed at the four corners of the bottom of the screen box. The screen box is provided with screen one, screen two and collection box from top to bottom.

[0007] The pretreatment mechanism includes a drum dryer, a slide rail parallel to one side of the screen box, and a slider slidably connected to the slide rail. The top of the drum dryer is provided with an air inlet, the top of the air inlet is provided with a fan, the inside of the air inlet is provided with a resistance wire, and the inner wall of the drum dryer is provided with a humidity sensor.

[0008] The anti-blocking mechanism includes a slide rail 2 disposed between screen 1 and screen 2, a slider 2 slidably connected to the slide rail 2, and a limiting cylinder fixed to the left and right sides of the slider 2. The two ends of the limiting cylinder are respectively attached to screen 1 and screen 2, and a bouncing ball is provided inside the limiting cylinder.

[0009] Furthermore, it also includes a protective mechanism, which includes a filter box located on one side of the sieve box. The top of the filter box is equipped with a second fan, the air outlet of the second fan extends into the filter box, and the air inlet of the second fan is sealed and connected to an air pipe. The air pipe is arranged vertically, and the end of the air pipe is sealed and connected to a dust suction hood. The opening of the dust suction hood faces the sieve box, and a filter layer is provided inside the filter box.

[0010] Furthermore, the aperture of the first screen is larger than that of the second screen, and both the first screen and the second screen are made of polyurethane.

[0011] Furthermore, one end of the first screen is provided with a discharge port one, and one end of the second screen is provided with a discharge port two.

[0012] Furthermore, one end of the slide rail one is provided with a drive motor one, and one end of the slide rail two is provided with a drive motor two.

[0013] Furthermore, a touch screen is provided on one side of the screen box, and a microcontroller is electrically connected to the inside of the touch screen. The microcontroller is electrically connected to the vibrator, the drum dryer, the first fan, the resistance wire, the humidity sensor, the first drive motor, the second drive motor, and the second fan.

[0014] Furthermore, the bouncing ball is made of rubber or polyurethane.

[0015] Furthermore, the filter layer has at least two layers, both of which are arranged in a horizontal direction, and both filter layers are activated carbon filter layers.

[0016] The technical effects and advantages of this utility model are as follows: The organic fertilizer screening device is advanced in design, compact in structure, and easy to use. By setting up a drum dryer and a humidity sensor, the organic fertilizer to be screened can be pre-dried to a set moisture content, avoiding excessively high or low moisture content. By setting up an anti-clogging mechanism, the vibrator drives the limiting cylinder to vibrate, and the bouncing ball will repeatedly hit the bottom of screen one and the top of screen two. The instantaneous impact force generated by the impact directly acts on the particles stuck in the screen holes, "loosening" or "shaking" them out of the screen holes. By setting up a protective mechanism, the fan two sucks the dust generated during screening into the dust collection hood and then into the filter box through the air pipe for filtration, which can effectively suppress dust and protect the working environment and workers' health.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] This utility model provides, for example Figure 1-3 The organic fertilizer screening device shown includes:

[0025] The screening mechanism 100 includes a screen box 101, a vibrator 102 fixed to one end of the screen box 101, and damping springs 103 fixed to the four corners of the bottom of the screen box 101. The screen box 101 is provided with a first screen 104, a second screen 105, and a collection box 106 from top to bottom. The vibrator 102 is a vibrating motor type vibrator, where the vibrating motor itself is the excitation source. Adjustable eccentric blocks are installed at both ends or one end of its rotor shaft. When the vibrating motor is energized and rotates, the internal eccentric blocks rotate synchronously at high speed, directly generating centrifugal force (excitation). The vibrating motor is directly and rigidly fixed to the side plate of the screen box 101 by high-strength bolts or flanges. The excitation force generated by the vibrating motor acts directly on the screen box 101, causing the entire screen box 101 to vibrate. The screen box 101 is supported on the foundation by damping springs 103 (or rubber springs, air springs, etc.). The damping springs 103 can support the weight of the entire screen box 101 and allow the screen box 101 to vibrate freely. They can also absorb most of the vibration energy, prevent or greatly reduce the vibration from being transmitted to the supporting structure and foundation, protect the equipment and building, and reduce noise.

[0026] The pretreatment mechanism 200 includes a drum dryer 201, a slide rail 202 parallel to one side of the screen box 101, and a slider 203 slidably connected to the slide rail 202. The drum dryer 201 has an air inlet 204 at its top, a fan 205 at its top, a resistance wire 206 inside the air inlet 204, and a humidity sensor 207 on the inner wall of the drum dryer 201. The drum dryer 201 is fixed to the top of the slider 203. The drum dryer... Machine 201 reciprocates along slide rail 202 via slider 203, which can evenly transport the pre-dried organic fertilizer to screen box 101. Fan 205 blows outside air into drum dryer 201 through air inlet 204. The air is heated when it passes through resistance wire 206. The hot air comes into full contact with the organic fertilizer in drum dryer 201 to evaporate the moisture in the organic fertilizer. When the drum dryer 201 rotates, the organic fertilizer comes into contact with humidity sensor 207, which facilitates real-time monitoring of the moisture content of the organic fertilizer.

[0027] The anti-blocking mechanism 300 includes a slide rail 301 disposed between screen 104 and screen 205, a slider 302 slidably connected to the slide rail 301, and limiting cylinders 303 fixed to the left and right sides of the slider 302. The two ends of the limiting cylinder 303 are respectively attached to screen 104 and screen 205. A bouncing ball 304 is provided inside the limiting cylinder 303. The vibrator 102 drives the limiting cylinder 303 to vibrate, and the bouncing ball 304 will repeatedly hit the bottom of screen 104 and the top of screen 205. The instantaneous impact force generated by the impact directly acts on the particles stuck in the screen holes, "loosening" or "shaking out" them from the screen holes. As long as the vibrator 102 is running, the bouncing ball 304 will continue to carry out this random impact activity, providing real-time and dynamic anti-blocking protection.

[0028] For example, see Figure 1 As shown, it also includes a protective mechanism 400, which includes a filter box 401 disposed on one side of the sieve box 101. A second fan 402 is provided on the top of the filter box 401. The air outlet of the second fan 402 extends into the filter box 401. An air pipe 403 is sealed and connected to the air inlet of the second fan 402. The air pipe 403 is arranged in a vertical direction, and a dust suction hood 404 is sealed and connected to the end of the air pipe 403. The opening of the dust suction hood 404 faces the sieve box 101. A filter layer 405 is provided inside the filter box 401.

[0029] In this technical solution, the dust generated during screening can be drawn into the dust collection hood 404 by the second fan 402, and then enter the filter box 401 through the air pipe 403. The dust is adsorbed and filtered when it passes through the filter layer 405.

[0030] For example, see Figures 1-2 As shown, the aperture of screen 104 is larger than that of screen 2 105. Both screen 104 and screen 2 105 are made of polyurethane screen.

[0031] In this technical solution, the organic fertilizer with larger particle size is retained on screen 104. The organic fertilizer passing through screen 104 can fall onto screen 2105 for further screening. The organic fertilizer with smaller particle size falls into the collection box 106 through screen 2105. The multi-layer screen can separate products of various specifications at the same time. The polyurethane screen has the advantages of wear resistance, corrosion resistance, non-clogging and good elasticity.

[0032] For example, see Figure 2 As shown, one end of screen 104 is provided with discharge port 107, and one end of screen 2 105 is provided with discharge port 2 108.

[0033] In this technical solution, the organic fertilizer on screen 104 and screen 205 can be conveniently discharged through discharge port 107 and discharge port 208 respectively.

[0034] For example, see Figures 2-3 As shown, one end of slide rail 202 is equipped with drive motor 208, and one end of slide rail 301 is equipped with drive motor 305.

[0035] In this technical solution, drive motor 208 provides power support for slider 203 to reciprocate along slide rail 202, thereby driving drum dryer 201 to reciprocate along slide rail 202 to achieve uniform feeding. Drive motor 305 provides power support for slider 302 to reciprocate along slide rail 301, thereby moving limit cylinder 303 to a designated position to facilitate enhanced impact on the blockage and improve the ability to clear blockages.

[0036] For example, see Figure 2 As shown, a touch screen display 109 is provided on one side of the screen box 101. A microcontroller is electrically connected to the inside of the touch screen display 109. The microcontroller is electrically connected to the vibrator 102, the drum dryer 201, the first fan 205, the resistance wire 206, the humidity sensor 207, the first drive motor 208, the second drive motor 305, and the second fan 402.

[0037] This technical solution facilitates the connection of various electrical appliances into a functional whole. It allows for the input of control commands through the touch screen 109 to coordinate and control the operation of each appliance, and also displays the operating status of each appliance on the touch screen 109 for easy observation by staff.

[0038] For example, the bouncing ball 304 is made of rubber or polyurethane.

[0039] In this technical solution, by selecting rubber or polyurethane materials, the bouncy ball 304 has the advantages of wear resistance and high elasticity, ensuring good resilience and durability. When the bouncy ball 304 is impacted, it will undergo elastic deformation and store energy, and then quickly restore its shape and bounce, gaining new speed and direction.

[0040] For example, see Figure 1 As shown, the filter layer 405 has at least two layers, both of which are arranged in the horizontal direction, and both filter layers 405 are activated carbon filter layers.

[0041] In this technical solution, activated carbon has a strong adsorption capacity. By setting at least two layers of activated carbon filter, the dust generated during screening can be fully adsorbed and filtered, resulting in a good filtration effect.

[0042] Working principle: When using the organic fertilizer screening device, the organic fertilizer is first transported to the drum dryer 201 for drying pretreatment. Then, the drive motor 208 is started to drive the drum dryer 201 to reciprocate along the slide rail 202. During the reciprocating motion, the pretreated organic fertilizer is evenly transported to the screen 104. Then, the vibrator 102 is started, which drives the screen box 101 to vibrate. The organic fertilizer is screened through the screen 104 and the screen 2 105 to separate organic fertilizer of different particle sizes. The bouncing ball 304 bounces in the limiting cylinder 303 and repeatedly hits the bottom of the screen 104 and the top of the screen 2 105 to shake out the blockage in the screen holes. Then, the fan 402 is started to adsorb the dust generated during the screening process into the filter box 401 for filtration. The organic fertilizer screening device features an advanced design, compact structure, and ease of use. By incorporating a drum dryer 201 and a humidity sensor 207, the organic fertilizer to be screened can be pre-dried to a set moisture content, preventing the moisture content from being too high or too low. An anti-clogging mechanism 300 is in place, and the vibrator 102 drives the limiting cylinder 303 to vibrate. Bouncing balls 304 repeatedly impact the bottom of screen one 104 and the top of screen two 105. The instantaneous impact force directly acts on the particles stuck in the screen holes, "loosening" or "shaking" them out of the screen holes. A protective mechanism 400 is in place, and a second fan 402 draws the dust generated during screening into a dust collection hood 404, which then enters a filter box 401 through an air pipe 403 for filtration. This effectively suppresses dust and protects the working environment and worker health.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
