[0004] In the production process of water-soluble fertilizers, because the production of water-soluble fertilizers requires mixing with more water, the materials are more likely to stick together, resulting in particles of different sizes, affecting the subsequent quality use. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a drum granulator for producing water-soluble fertilizers to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a drum granulator for water-soluble fertilizer production, comprising a base, the top of the base is rotatably connected to a drum, the right side of the base is fixedly connected to a feed pipe, the inner wall of the drum is fixedly connected to an elastic filter layer, the outer wall of the drum is provided with filter holes, the outer wall of the base is fixedly connected to a granulating mechanism, the airflow is blown onto the elastic filter layer through the filter holes, thereby increasing the evaporation rate of water on the material, the evaporation of water prevents subsequent particles from continuing to adhere to the material, and condenses when the material initially has water, and the evaporation of water on the particles under the continuous blowing of the subsequent airflow can prevent the subsequent particles from adhering to the particles again, thereby ensuring the uniform size of the particles;

[0007] The rubbing mechanism comprises:

[0008] A first bracket, wherein the first bracket is fixedly connected to an outer wall of the base;

[0009] A first mounting block, wherein the first mounting block is fixedly connected to the right side of the base, and a second mounting block is fixedly connected to the left side of the base;

[0010] An airbag is fixedly connected between the first mounting block and the second mounting block.

[0011] Preferably, a first fan is fixedly connected to the outer wall of the first bracket, and the first fan is connected to the interior of the airbag through a first mounting block. When the airbag is inflated, it contacts a round roller, and the airbag is squeezed and wrinkled due to the rotational friction of the round roller. The appearance of the wrinkles cooperates with the friction of the rotation of the elastic filter layer, thereby making it easier for material adhering to the elastic filter layer to be extruded and formed. The appearance of the wrinkles increases the friction force on the elastic filter layer, ensuring that the material on the inner wall of the elastic filter layer is rubbed off, and the material is easier to be extruded and formed in the wrinkles of the airbag, thereby ensuring the extrusion efficiency of the material.

[0012] Preferably, the outer wall of the first bracket is also fixedly connected to the second motor, the outer wall of the second motor is rotatably connected to the round roller, the left side of the round roller is rotatably connected to the bearing, and the bearing is fixedly connected to the left side of the base, the airbag is in active contact with the elastic filter layer, the round roller is in active contact with the airbag, the elastic filter layer first filters the moisture in the material, and then the water flows out through the filter holes on the drum, and the viscosity of the remaining material is reduced by filtering the moisture, which is convenient for extruding the material, and the material of the elastic filter layer presents strips during the rolling process, and the airbag contacts the elastic filter layer when it is bulging. Both the airbag and the elastic filter layer are made of elastic material, so when the two are squeezed against each other, the material is rubbed and then rubbed into small pieces, ensuring that the material is extruded, and the drum has a certain inclination, so the material is movable on the elastic filter layer, and the extrusion of the airbag and the elastic filter layer is coordinated to ensure that the material is extruded into particles, and the extrusion force of the airbag and the elastic filter layer is the same, and the distance between the round roller and the elastic filter layer is the same, and the round roller intercepts the particles again to ensure that the size of the particles is uniform.

[0013] Preferably, a gear ring is fixedly connected to the outer wall of the drum, and a first motor is fixedly connected to the outer wall of the base.

[0014] Preferably, the outer wall of the first motor is rotatably connected with a gear, and the gear is meshingly connected with a ring gear.

[0015] Preferably, an airflow impact mechanism is fixedly connected to the back side of the base, and the airflow impact mechanism includes a second fan, and the second fan is fixedly connected to the back side of the base.

[0016] Preferably, a zigzag tube is fixedly connected to the top of the second fan, and an airflow bin is fixedly connected to the top of the zigzag tube. An airflow port is opened on the outer wall of the airflow bin. When the airflow bin changes the position where the airflow is blown out, the position where the elastic filter layer is impacted by the airflow is also different, so that other positions of the elastic filter layer are bulged, and the bulging of the elastic filter layer is tortuous. The tortuosity of the elastic filter layer causes a gap to be formed between the adhered material and the elastic filter layer, which facilitates the falling of the adhered material on the elastic filter layer, avoids the subsequent mixing of particles with the material adhered to the elastic filter layer, and ensures the uniformity of the particle size.

[0017] Preferably, the outer wall of the base is fixedly connected to a second bracket, the top of the second bracket is fixedly connected to an electric slider, the outer wall of the airflow bin is fixedly connected to a slide rail, and the slide rail is slidably connected to the electric slider.

[0018] The present invention provides a drum granulator for producing water-soluble fertilizers. It has the following beneficial effects:

[0019] 1. The drum granulator used for the production of water-soluble fertilizer first filters the moisture in the material through the elastic filter layer, and then the water flows out through the filter holes on the drum. The viscosity of the remaining material is reduced by filtering the moisture, which is convenient for extruding the material. The material of the elastic filter layer is in strips during the rolling process. The airbag contacts the elastic filter layer when it is bulging. The airbag and the elastic filter layer are both made of elastic materials, so the material is rubbed when the two are squeezed against each other, and then the material is rubbed into small pieces, ensuring that the material is extruded. In addition, the drum has a certain inclination, so the material is movable on the elastic filter layer, and the extrusion of the airbag and the elastic filter layer ensures that the material is extruded into particles. The extrusion force of the airbag and the elastic filter layer is the same, and the distance between the round roller and the elastic filter layer is the same. The round roller intercepts the particles again to ensure that the particles are uniform in size.

[0020] 2. The drum granulator used for the production of water-soluble fertilizers, when the airbag is inflated and bulged, contacts the round roller, and the airbag is squeezed and wrinkled under the friction of the round roller's rotation. The appearance of wrinkles, in combination with the friction of the rotation of the elastic filter layer, makes it easier for the material adhering to the elastic filter layer to be extruded and formed. The appearance of wrinkles increases the friction force on the elastic filter layer, ensuring that the material on the inner wall of the elastic filter layer is rubbed off, and the material is easier to be extruded and formed in the wrinkles of the airbag, ensuring the extrusion efficiency of the material.

[0021] 3. The drum granulator used for the production of water-soluble fertilizers increases the evaporation rate of water on the material by blowing the air through the filter holes onto the elastic filter layer. The evaporation of water prevents subsequent particles from continuing to adhere to the material. When the material initially has moisture, it condenses. With the continuous blowing of the subsequent airflow, the evaporation of water on the particles can prevent subsequent particles from adhering to the particles again, ensuring uniform particle size.

[0022] 4. The drum granulator used for the production of water-soluble fertilizers changes the position of the airflow through the airflow bin, and the position of the elastic filter layer impacted by the airflow is also different, so that other positions of the elastic filter layer bulge, and the bulging of the elastic filter layer will be tortuous. The tortuosity of the elastic filter layer causes a gap between the adhered material and the elastic filter layer, which is convenient for the falling of the adhered material on the elastic filter layer, avoids the subsequent particles from mixing with the material adhered to the elastic filter layer, and ensures the uniform size of the particles.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] For example, see Figure 1-7 The present invention provides a technical solution: a drum granulator for water-soluble fertilizer production, comprising a base 3, a drum 1 is rotatably connected to the top of the base 3, a feeding pipe 2 is fixedly connected to the right side of the base 3, an elastic filter layer 9 is fixedly connected to the inner wall of the drum 1, a filter hole 10 is opened on the outer wall of the drum 1, and a granulating mechanism 7 is fixedly connected to the outer wall of the base 3;

[0035] The rubbing mechanism 7 comprises:

[0036] A first bracket 72, the first bracket 72 is fixedly connected to the outer wall of the base 3;

[0037] A first mounting block 75, the first mounting block 75 is fixedly connected to the right side of the base 3, and a second mounting block 76 is fixedly connected to the left side of the base 3;

[0038] The airbag 74 is fixedly connected between the first mounting block 75 and the second mounting block 76 .

[0039] The outer wall of the first bracket 72 is fixedly connected to the first fan 71, and the first fan 71 is connected to the inside of the airbag 74 through the first mounting block 75. When the airbag 74 is inflated and bulged, it contacts the round roller 78. Under the rotational friction of the round roller 78, the airbag 74 is squeezed and wrinkles appear. The appearance of wrinkles, in combination with the friction of the rotation of the elastic filter layer 9, makes it easier for the material adhered to the elastic filter layer 9 to be extruded and formed. The appearance of wrinkles increases the friction force on the elastic filter layer 9, ensuring that the material on the inner wall of the elastic filter layer 9 is rubbed off, and the material is easier to be extruded and formed in the wrinkles of the airbag 74, ensuring the extrusion efficiency of the material.

[0040] The outer wall of the first bracket 72 is also fixedly connected to the second motor 73, and the outer wall of the second motor 73 is rotatably connected to a round roller 78. The left side of the round roller 78 is rotatably connected to a bearing 77, and the bearing 77 is fixedly connected to the left side of the base 3. The airbag 74 is in active contact with the elastic filter layer 9, and the round roller 78 is in active contact with the airbag 74. The elastic filter layer 9 first filters the moisture in the material, and then the water flows out through the filter holes 10 on the drum 1. The viscosity of the remaining material is reduced by filtering the moisture, which is convenient for extruding the material. The elastic filter layer 9 presents a strip shape during the rolling process, and the airbag 74 is bulging. When the roller 1 is in contact with the elastic filter layer 9, the airbag 74 and the elastic filter layer 9 are both made of elastic materials, so when the two are squeezed against each other, the material is rubbed and then rubbed into small pieces, ensuring that the material is extruded and formed, and the roller 1 has a certain slope, so the material is movable on the elastic filter layer 9, and the extrusion of the airbag 74 and the elastic filter layer 9 ensures that the material is extruded into particles. The extrusion forces of the airbag 74 and the elastic filter layer 9 are the same, and the distance between the round roller 78 and the elastic filter layer 9 is the same, and the round roller 78 intercepts the particles again to ensure that the particles are uniform in size.

[0041] A gear ring 6 is fixedly connected to the outer wall of the drum 1 , and a first motor 4 is fixedly connected to the outer wall of the base 3 .

[0042] The outer wall of the first motor 4 is rotatably connected with a gear 5 , and the gear 5 is meshingly connected with a gear ring 6 .

[0043] When in use, the drum 1 and the base 3 are rotatably installed, and the drum 1 and the base 3 are mutually engaged, thereby limiting the position of the drum 1. The left side of the drum 1 is slightly lower than the right side of the drum 1, so during the granulation process, the particles will continuously move to the left, and then a receiving box is set on the left side, and the first motor 4 is powered on to start and drive the rotation of the gear 5, and the gear 5 is meshed and connected with the ring gear 6 to drive the rotation of the drum 1, and the mixed material required for granulation is put into the feeding pipe 2, and flows into the drum 1 under the guidance of the feeding pipe 2, and the elastic filter layer 9 first filters the moisture in the material, and then the water flows out through the filter holes 10 on the drum 1, and the remaining material is located on the elastic filter layer 9. When the drum 1 drives the elastic filter layer 9 to rotate, the material is located on the elastic filter layer 9 and rolls, and rolls in the direction of the airbag 74. During the rolling process The material is in strip shape. The first mounting block 75 and the second mounting block 76 are fixed on the base 3 and are located on both sides of the drum 1. Then the airbag 74 is fixed therebetween. The first fan 71 is powered on and started to blow air into the airbag 74. The airbag 74 then swells. When the airbag 74 swells, it contacts the elastic filter layer 9. Both the airbag 74 and the elastic filter layer 9 are made of elastic materials, so when the two are squeezed against each other, the material is rubbed and then rubbed into small pieces. The second motor 73 is powered on and started to drive the round roller 78 in the same direction of rotation as the drum 1. When the airbag 74 is inflated and swells, it contacts the round roller 78. Under the rotational friction of the round roller 78, the airbag 74 is squeezed and wrinkles appear. The appearance of the wrinkles is in cooperation with the friction of the rotation of the elastic filter layer 9, so that the material adhering to the elastic filter layer 9 is easier to be extruded and formed.

[0044] For example 2, please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution:

[0045] An airflow impact mechanism 8 is fixedly connected to the back side of the base 3 . The airflow impact mechanism 8 includes a second fan 81 . The second fan 81 is fixedly connected to the back side of the base 3 .

[0046] A zigzag pipe 82 is fixedly connected to the top of the second fan 81 , an airflow bin 83 is fixedly connected to the top of the zigzag pipe 82 , and an airflow port 84 is formed on the outer wall of the airflow bin 83 .

[0047] The outer wall of the base 3 is fixedly connected with a second bracket 87 , the top of the second bracket 87 is fixedly connected with an electric slider 86 , the outer wall of the airflow compartment 83 is fixedly connected with a slide rail 85 , and the slide rail 85 is slidably connected to the electric slider 86 .

[0048] When in use, the second fan 81 is powered on and started to blow air into the airflow bin 83 through the zigzag tube 82. The airflow port 84 is located adjacent to the airbag 74. Then the airflow port 84 blows air onto the drum 1. The airflow passes through the filter hole 10 and blows onto the elastic filter layer 9, thereby increasing the evaporation rate of the water on the material. Then, the material is also caused to fall from the elastic filter layer 9 under the impact of the airflow. The electric slider 86 is powered on and started to drive the slide rail 85 to move up and down. The lifting and lowering of the slide rail 85 drives the lifting and lowering of the airflow bin 83. When the airflow bin 83 changes the position where the airflow is blown out, the position where the elastic filter layer 9 is impacted by the airflow is also different. Then, when the airflow bin 83 rises to the top or bottom position of the airbag 74, other positions of the elastic filter layer 9 are bulged, and the bulging of the elastic filter layer 9 is zigzag. The zigzag of the elastic filter layer 9 causes a gap between the adhered material and the elastic filter layer 9. Under the continuous rotation of the drum 1, the material in the drum 1 falls from the left side of the elastic filter layer 9 along a certain slope.
