Description

Technical Field

[0001] This utility model relates to the field of granulator technology, specifically to a microbial agent granulator for microbial fertilizer production. Background Technology

[0002] Microbial fertilizers, as a highly efficient and environmentally friendly bio-fertilizer, play an increasingly important role in modern agriculture. They promote soil nutrient transformation, increase crop yields, and improve the soil ecological environment by inoculating beneficial microorganisms into organic or inorganic substrates. In the production of microbial fertilizers, granulation of the microbial agent is one of the key processes, directly affecting the product's physical form, ease of application, and microbial activity.

[0003] Currently, most commonly used microbial agent granulation equipment employs roller extrusion molding, where two relatively rotating rollers compress the raw material to form granules. However, in practical applications, the following problems exist: First, due to prolonged continuous operation, friction and compression between the rollers generate a large amount of heat, causing the roller temperature to rise. This can easily deactivate temperature-sensitive microorganisms, thus affecting the biological activity and fertilizer efficacy of the microbial fertilizer. Second, after granulation, some granules adhere to the forming grooves on the roller surface, making them difficult to detach. This not only affects subsequent granulation efficiency but may also cause the granules to break under pressure, reducing the yield. Therefore, a microbial agent granulator for microbial fertilizer production is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a microbial agent granulator for the production of microbial fertilizers, which has the advantages of good roller cooling effect, thorough particle peeling, and convenient cleaning and maintenance, and solves the problems of microbial inactivation and particle adhesion that are difficult to remove due to temperature rise in existing equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a microbial fertilizer production agent granulator, comprising a granulator body, wherein a cooling mechanism and a stripping brush are provided inside the granulator body;

[0006] The granulator body includes a support frame, a material cylinder, a drive motor, a first roller, and a second roller. The material cylinder is fixedly mounted on the support frame, and the first roller and the second roller are rotatably connected to the material cylinder. The drive motor is fixedly mounted on the support frame to drive the first roller and the second roller. A refrigerant chamber is provided inside the first roller and the second roller. The cooling mechanism includes a central shaft tube, a refrigerant inlet, a refrigerant inner outlet, a refrigerant outer outlet, and a refrigerant return port. The side end faces of the first roller and the second roller are provided with shaft holes that rotatably cooperate with the central shaft tube.

[0007] As a preferred embodiment of the microbial fertilizer production agent granulator of this utility model, a baffle is provided inside the central shaft tube, which divides the central cylinder into a refrigerant inlet channel and a refrigerant return channel. The refrigerant inlet and refrigerant inner outlet are connected to the refrigerant inlet channel, and the refrigerant outer outlet and refrigerant return port are connected to the refrigerant return channel.

[0008] In a preferred embodiment of the microbial fertilizer production agent granulator of this utility model, the bottom of the refrigerant inner outlet is flush with the bottom of the refrigerant cavity, and the top of the refrigerant return port is flush with the top of the refrigerant cavity.

[0009] In a preferred embodiment of the microbial fertilizer production agent granulator of this utility model, the refrigerant return port is located at the end of the central shaft tube away from the refrigerant inner outlet.

[0010] As a preferred embodiment of the microbial fertilizer production agent granulator of this utility model, the material stripping brush includes a brush rod and brush bristles. The brush rod is inserted into the material cylinder and slidably connected thereto. The surfaces of the first roller and the second roller are provided with spherical grooves. The brush bristles are in contact with the bottom of the first roller and the second roller.

[0011] As a preferred embodiment of the microbial fertilizer production agent granulator of this utility model, the material cylinder is provided with a leak-proof baffle, and the side end face of the leak-proof baffle is provided with a positioning groove that slides with the brush rod.

[0012] As a preferred embodiment of the microbial fertilizer production agent granulator of this utility model, the end of the brush rod is provided with a pull ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model sets up a refrigerant chamber inside the first and second rollers, and is equipped with a central shaft tube circulation cooling mechanism. After the refrigerant fills the refrigerant chamber through the inlet and the inner outlet, it is discharged from the far end return port, forming a transverse circulation flow. This structure ensures that the refrigerant fully covers the inside of the rollers and evenly absorbs the heat generated by the extrusion friction. It directly solves the problem of microbial agent inactivation caused by the continuous friction and heating of the rollers during the granulation process, and ensures the biological activity and fertilizer efficiency stability of the microbial fertilizer. The design of the refrigerant inner outlet being flush with the bottom of the chamber and the return port being flush with the top of the chamber further eliminates the dead corners of the air chamber in the refrigerant chamber and improves the overall cooling efficiency.

[0015] 2. This utility model employs a structure that combines a stripping brush with a spherical groove on the roller surface. The brush bristles adhere tightly to the bottom of the roller, immediately sweeping away the microbial agent particles adhering to the spherical groove after granulation. Simultaneously, a leak-proof baffle is fixed to the position of the brush rod via a side positioning groove, preventing particles from being squeezed in the gap between the baffles. This design solves the problem of difficult peeling caused by particles sticking to the roller in traditional granulation and prevents particle breakage caused by subsequent mechanical extrusion, significantly improving the yield of intact particles and product quality. Furthermore, the sliding connection structure between the brush rod and the cylinder allows for quick disassembly and cleaning after production, thoroughly removing residual microbial agent and eliminating the hidden danger of bacteria growth in cleaning dead corners in complex mechanical structures.

[0025] Please see Figures 1-8 A microbial fertilizer production agent granulator includes a granulator body 1, and a cooling mechanism 2 and a stripping brush 3 are provided inside the granulator body 1;

[0026] The main body 1 of the pellet mill includes a support frame 101, a material cylinder 102, a drive motor 103, a first roller 104 and a second roller 105. The material cylinder 102 is fixedly installed on the support frame 101. The first roller 104 and the second roller 105 are installed inside the material cylinder 102 and rotatably connected to it. The drive motor 103 is fixedly installed on the support frame 101 to drive the first roller 104 and the second roller 105. A refrigerant chamber 108 is provided inside the first roller 104 and the second roller 105. The cooling mechanism 2 includes a central shaft tube 201, a refrigerant inlet 202, a refrigerant inner outlet 203, a refrigerant outer outlet 204 and a refrigerant return port 205. The side end faces of the first roller 104 and the second roller 105 are provided with shaft holes 110 that rotatably cooperate with the central shaft tube 201.

[0027] The drive motor 103 drives the first roller 104 to rotate via a synchronous belt and synchronous pulley. The first roller 104 and the second roller 105 are driven by gear meshing. The first roller 104 and the second roller 105 are used for extrusion granulation. The cooling mechanism 2 circulates coolant into the first roller 104 and the second roller 105 to cool them down and avoid continuous friction and extrusion, which could cause the equipment to heat up and deactivate the microbial agent. The peeling brush 3 brushes off the granulated microbial agent particles to prevent the particles from adhering to the first roller 104 and the second roller 105 and being difficult to peel off.

[0028] Furthermore, a baffle 206 is provided inside the central shaft tube 201, which divides the central cylinder into a refrigerant inlet channel 207 and a refrigerant return channel 208. The refrigerant inlet 202 and the refrigerant inner outlet 203 are connected to the refrigerant inlet channel 207, and the refrigerant outer outlet 204 and the refrigerant return port 205 are connected to the refrigerant return channel 208.

[0029] The refrigerant is transported through the central shaft tube 201, which provides a stable circulating refrigerant liquid to the first roller 104 and the second roller 105 during their rotation. The refrigerant flows from the refrigerant inlet 202 through the refrigerant inlet channel 207 and into the refrigerant chamber 108 from the refrigerant inner outlet 203. Then it flows from the refrigerant return port 205 through the refrigerant return channel 208 to the refrigerant outer outlet 204 for discharge, thereby realizing refrigerant circulation.

[0030] Furthermore, the bottom of the refrigerant inlet 203 is flush with the bottom of the refrigerant cavity 108, and the top of the refrigerant return port 205 is flush with the top of the refrigerant cavity 108.

[0031] This ensures that the refrigerant fills the entire refrigerant cavity 108 after flowing into it, thereby preventing the presence of cavities within the refrigerant cavity 108 that could affect the cooling effect.

[0032] Furthermore, the refrigerant return port 205 is located at the end of the central shaft tube 201 that is far from the refrigerant inner outlet 203.

[0033] The refrigerant return port 205 and the refrigerant inner outlet 203 are set at the left and right ends of the central shaft tube 201 to ensure that the refrigerant can flow laterally in the refrigerant cavity 108, thereby improving the uniformity of cooling and avoiding local overheating that could lead to the inactivation of the bacterial agent.

[0034] Furthermore, the stripping brush 3 includes a brush rod 301 and bristles 302. The brush rod 301 is inserted into the material cylinder 102 and slidably connected thereto. The surfaces of the first roller 104 and the second roller 105 are provided with spherical grooves 107. The bristles 302 are attached to the bottom of the first roller 104 and the second roller 105.

[0035] If the extruded bacterial agent particles adhere to the spherical groove 107, the bristles 302 on the brush rod 301 will sweep the bacterial agent particles off, thereby separating the bacterial agent particles from the equipment, avoiding crushing of the particles due to compression with the anti-leakage baffle 106, and improving product yield.

[0036] Furthermore, a leak-proof baffle 106 is provided inside the material cylinder 102, and a positioning groove 109 is provided on the side end face of the leak-proof baffle 106 to slide and cooperate with the brush rod 301.

[0037] The positioning groove 109 penetrates the front and rear end faces of the material cylinder 102. The positioning groove 109 holds the brush rod 301 in place, thereby preventing the brush rod 301 from sliding. The sliding connection structure allows the brush rod 301 to be directly pulled out from the front face of the material cylinder 102 for cleaning, thus preventing the growth of bacteria.

[0038] Furthermore, a pull ring 303 is provided at the end of the brush rod 301.

[0039] The pull ring 303 makes it easy to pull the brush rod 301 out of the positioning groove 109, thus avoiding the brush rod 301 from being completely inserted into the positioning groove 109 and being inconvenient to remove, which would affect the disassembly and cleaning of the stripping brush 3.

[0040] When using this device, first place the equipment on a stable surface, ensuring that the support frame 101 firmly supports the material cylinder 102. Start the drive motor 103, which drives the first roller 104 to rotate via a synchronous belt and synchronous pulley. The first roller 104 then drives the second roller 105 to rotate via gear meshing. The raw material of the microbial agent to be granulated is put into the material cylinder 102, and granulation is carried out under the extrusion action of the first roller 104 and the second roller 105. At the same time, refrigerant is introduced into the refrigerant inlet 202 of the cooling mechanism 2. The refrigerant flows through the refrigerant inlet channel 207 in the central shaft tube 201 and flows into the refrigerant chamber 108 of the first roller 104 and the second roller 105 from the refrigerant outlet 203. Since the bottom of the refrigerant outlet 203 is flush with the bottom of the refrigerant chamber 108, the refrigerant can smoothly fill the entire refrigerant chamber 108. The refrigerant flows in the refrigerant chamber 108, absorbing the refrigerant from the rollers. The heat generated by friction and extrusion flows out through the refrigerant return port 205, located at the end of the central shaft tube 201 away from the refrigerant inner outlet 203 and with its top flush with the top of the refrigerant cavity 108. It is then discharged from the refrigerant outer outlet 204 through the refrigerant return channel 208, realizing refrigerant circulation. This effectively reduces the roller temperature and prevents the bacterial agent from becoming inactive due to equipment overheating. During granulation, if the bacterial agent particles adhere to the spherical grooves 107 on the surfaces of the first roller 104 and the second roller 105, the bristles 302 of the stripping brush 3, which is attached to the bottom of the roller, will sweep the particles off, preventing particle adhesion. When it is necessary to clean the stripping brush 3, pull the pull ring 303 at the end of the brush rod 301 to pull the brush rod 301 out of the positioning groove 109 on the side end face of the anti-leakage baffle 106 inside the material cylinder 102 for cleaning. After cleaning, the brush rod 301 is reinserted into the positioning groove 109, which locks the brush rod 301 to prevent it from sliding.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
