Description

Technical Field

[0001] This invention belongs to the technical field of water-soluble fertilizer preparation equipment, specifically relating to a peptide water-soluble fertilizer grinding and mixing device. Background Technology

[0002] Modern agriculture continues to develop towards refinement and efficiency, and the market's requirements for the comprehensive quality of functional water-soluble fertilizers are constantly increasing. Soybean peptide water-soluble fertilizer is rich in natural bioactive peptides and a variety of nutrients, which are easily absorbed and utilized by crops, resulting in outstanding yield and quality improvement effects. It is now widely used in various large-scale planting scenarios, and the market demand is steadily increasing. Soybean peptide raw materials have a special texture and need to be thoroughly ground to ensure the fineness and activity of the material. The raw soybean peptide material has coarse particles and uneven particle size, and there is particle agglomeration. In order to ensure the fineness of the material and fully preserve the natural biological activity of soybean peptides, the industry generally adopts wet grinding process to refine the raw materials. Soybean peptide materials after wet grinding have a uniform texture and stable activity, and need to be combined with stirring and mixing to complete the fusion of excipients. The existing peptide water-soluble fertilizer industry is mainly produced by small and medium-sized factories. Due to the limited funds of small and medium-sized factories, grinding and mixing processes need to be carried out separately, and the intermediate transportation is completed by workers. Grinding equipment often uses a double-roller grinding method, which involves the material passing from top to bottom between the two rollers, resulting in only one grinding process. Furthermore, the gap between the rollers is not easily adjustable, making it impossible to perform continuous grinding multiple times. This limited grinding effect significantly impacts the quality of the peptide aqueous solution. In addition, the material needs to be premixed before being mixed with additives, and subsequent homogenization is required. This processing method can only process materials in batches, and manual intervention is needed for some parts of the workflow. The overall coordination between the grinding and mixing equipment is poor. Summary of the Invention

[0003] To address the shortcomings of the prior art, the present invention aims to provide a peptide water-soluble fertilizer grinding and mixing device. This device is equipped with a spiral channel grinding roller. The spiral channel allows the material to slide downwards and continuously pass through the grinding roller, thereby achieving multiple grinding processes. Furthermore, a water injection device enables multiple water additions to the material, gradually wetting it and facilitating wet grinding while also promoting downward sliding. The three-chamber structure design enables pre-mixing, additive mixing, and deep homogenization of the material. The three mixing chambers can operate simultaneously, and by staggering their working times, work efficiency can be increased, achieving continuous material processing.

The control valve is set on the corresponding liquid discharge pipe.

[0008] Furthermore, the spraying device includes several spray pipes and several spray nozzles. The spray pipes are respectively arranged in the upper part of the mixing chamber, and the spray nozzles are respectively fixedly installed at the bottom of the spray pipes and evenly distributed. The spray nozzles are interconnected with the inside of the spray pipes. One end of each spray pipe is fixedly connected to a movable pipe and interconnected. The other end of the spray pipe is sealed.

[0009] Furthermore, the stirring device includes several impellers, a sealing groove plate, and a transmission gear set. The bottom surface of the sealing groove plate has a sealing groove. The transmission gear set includes a driving gear and several driven gears. The sealing groove plates are fixedly installed on the bottom surface of the mixing chamber. The transmission gear set is located inside the sealing groove. The driving gear is fixedly installed on the outer periphery of the movable tube. The impellers are evenly distributed in their respective mixing chambers. The mounting shaft of the impeller passes through the top surface of the sealing groove plate and is rotatably connected.

[0010] Furthermore, the rotating device is a rotating motor, which is fixedly installed on the bottom surface of the mixing tank.

The output shaft of the rotating motor is fixedly connected to the lower end of the movable tube.

[0011] Furthermore, the feeding device includes a mounting plate, a feeding hopper, a feeding pipe, and a regulating valve.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. An example of this invention is a peptide water-soluble fertilizer grinding and mixing device. Material is added through the feed inlet and slides along a spiral channel. A drive device rotates the grinding rollers, allowing the material to pass between them. The shearing force between the rollers grinds the material. A liquid injection device adds water into the spiral channel, facilitating the downward sliding of the material and gradually increasing its moisture content. The material is gradually ground from coarse to fine grinding, and finally falls into the upper mixing chamber of the mixing box. A spraying device adds water, a stirring device premixes the material, a liquid discharge structure adds material from the upper mixing chamber to the middle mixing chamber, and a feeding device adds additives to the middle mixing chamber. The material is mixed with additives, and finally, the liquid-feeding structure passes the material from the middle mixing chamber into the lower mixing chamber for final deep homogenization. The material is then discharged through the discharge pipe and enters the next process. Compared with existing technologies, this invention features a spiral channel grinding roller. The spiral channel allows the material to slide downwards and continuously pass through the grinding roller, achieving multiple grinding processes. Furthermore, the water injection device allows for multiple water additions to the material, gradually wetting it and facilitating wet grinding while also promoting downward sliding. The three-chamber design enables pre-mixing, additive mixing, and deep homogenization of the material. The three mixing chambers can operate simultaneously, and by staggering their working times, work efficiency is increased, enabling continuous material processing.

An example of the present invention is a peptide water-soluble fertilizer grinding and mixing device, in which water in the inlet pipe can be sprayed out from the injection nozzle along the connecting pipe, thereby spraying to various positions of the spiral channel. The injection device has a simple structure and is easy to use.

[0014] 3. In the peptide water-soluble fertilizer grinding and mixing device of the present invention, when the drive motor is turned on, the output shaft of the drive motor can drive the grinding roller to rotate. Since the grinding roller is driven to rotate by different drive motors, by controlling the rotation speed of the output shaft of the drive motor, a speed difference can be generated between the grinding rollers in the same group, so that the material is subjected to greater shear force when passing through the grinding roller, which is beneficial to the grinding process of the material.

[0015] 4. The peptide water-soluble fertilizer grinding and mixing device of the present invention can control the downward flow of liquid in the upper mixing chamber by adjusting the control valve on the lower liquid pipe, so as to carry out further processing.

[0016] 5. In an example of the present invention, a peptide water-soluble fertilizer grinding and mixing device is provided. Water in the movable tube can be sprayed out along the spray pipe. In addition, the rotation of the movable tube can drive the spray pipe and the spray nozzle to rotate, thereby increasing the spraying range of the spray nozzle and facilitating the stirring and mixing of materials.

[0017] 6. The present invention provides a peptide water-soluble fertilizer grinding and mixing device. The rotation of the movable tube can drive the impeller to rotate through the transmission gear set, thereby the impeller can stir and mix the material. The stirring device has a simple structure and is easy to use.

[0018] 7. An example of the present invention is a peptide water-soluble fertilizer grinding and mixing device. When the rotating motor is turned on, the output shaft of the rotating motor can drive the movable tube to rotate. The rotating device has a simple structure and is easy to use.

[0024] like Figure 1-3As shown, a peptide water-soluble fertilizer grinding and mixing device includes a grinding tank 1 and a mixing chamber 2. The grinding tank 1 is fixedly installed on the top surface of the mixing chamber 2. The bottom surface of the grinding tank 1 is open and communicates with the mixing chamber 2. A vertical pipe 3 is fixedly installed inside the grinding tank 1, and the upper end of the vertical pipe 3 penetrates through the grinding tank 1. A spiral channel 4 is provided between the inner wall of the grinding tank 1 and the vertical pipe 3. A feed inlet is provided on the top surface of the grinding tank 1, and a feed hopper is fixedly installed at the feed inlet. One or more multi-segment grinding rollers 5 are provided inside the grinding tank 1. This invention is equipped with two... The grinding rollers 5 consist of two rollers per group. Each grinding roller 5 passes through a spiral channel 4 and is rotatably connected. A through hole is provided in the spiral channel, and a horizontally positioned mounting plate is fixedly installed at the through hole. Each segment of the grinding roller 5 passes through the mounting plate and is rotatably connected. Each segment of the grinding roller 5 is located between corresponding spiral channels, and the gap between the grinding roller segments gradually decreases from top to bottom. A drive device for rotating the grinding rollers 5 is provided on the top surface of the grinding tank 1. A water inlet pipe 6 is installed inside the vertical pipe 3, and the water inlet pipe 6 is connected to the vertical pipe 3. A liquid injection device is installed between the spiral channels 4 and 5. The liquid injection device can add water to the spiral channel 4. Two partitions 7 are installed inside the mixing tank 2, dividing the mixing tank into three mixing chambers. A liquid discharge structure connecting the upper and lower parts of the partitions 7 is installed on one side of the mixing tank 2. The cyclic working mode of the three mixing chambers in the same period is as follows: upper mixing chamber: feeding-mixing-discharging; middle mixing chamber: processing-mixing-feeding; lower mixing chamber: discharging-feeding-mixing. A spraying device and a stirring device are respectively installed in each mixing chamber. The lower part of the water inlet pipe 6... The unit is equipped with a water flow valve, which can control the water flow of the spraying device. The lower end of the water inlet pipe 6 is rotatably installed with a movable pipe 8, which passes through the partition 7 and is rotatably connected. The bottom of the mixing box 2 is equipped with a rotating device that drives the movable pipe 8 to rotate. A feeding device that communicates with the middle mixing chamber is provided on one side of the mixing box 2. A discharge pipe 9 with a shut-off valve is fixedly installed on one side of the mixing box 2. The water flow valve and the shut-off valve are electromagnetic valves, which can be connected to the PLC controller for easy control.The material is added through the feed inlet and slides along the spiral channel 4. The drive device rotates the grinding rollers 5, allowing the material to pass between them. The shearing force between the rollers grinds the material. A liquid injection device adds water to the spiral channel 4, facilitating the downward sliding of the material and gradually increasing its moisture content. This process progresses from coarse to fine grinding. Finally, the material falls into the upper mixing chamber of the mixing box 2. A spray device adds water, and a stirring device premixes the material. A liquid discharge structure adds material from the upper mixing chamber to the middle mixing chamber. A feeding device adds additives to the middle mixing chamber, further mixing the material and additives. The mixture is then mixed, and finally, the liquid-lowering structure passes the material from the middle mixing chamber into the lower mixing chamber for final deep homogenization. The material is then discharged along the discharge pipe 9 and enters the next process. Compared with existing technologies, this invention features a spiral channel grinding roller 5. The spiral channel allows the material to slide downwards and continuously pass through the grinding roller 5, thus achieving multiple grinding processes. Furthermore, the water injection device allows for multiple water additions to the material, gradually wetting it and facilitating wet grinding. This also facilitates downward sliding of the material. The three-chamber structure enables pre-mixing, additive mixing, and deep homogenization of the material. The three mixing chambers can operate simultaneously, and by staggering their working times, work efficiency is increased, enabling continuous material processing.

[0025] like Figure 1-3 As shown, in a further preferred embodiment, the injection device comprises several injection nozzles 7. The injection nozzles 7 are evenly distributed around the outer periphery of the vertical pipe 3. The injection nozzles 7 are fixedly connected to and interconnect with the water inlet pipe 6 via connecting pipes. Water in the water inlet pipe 6 can be sprayed out from the injection nozzles 7 along the connecting pipes, thereby reaching various positions in the spiral channel 4. This injection device has a simple structure and is easy to use.

[0026] like Figure 1-3 As shown, in a further preferred embodiment, the driving device comprises multiple drive motors 10. The drive motors 10 are industrial servo motors, which can be controlled by a servo control system, facilitating the control of the output shaft speed of the drive motors 10. The drive motors 10 are fixedly mounted on the top of the grinding jar 1, and their output shafts pass through the grinding jar 1 and are rotatably connected. When the drive motors 10 are turned on, their output shafts drive the grinding rollers 5 to rotate. Because the grinding rollers 5 are driven to rotate by different drive motors 10, controlling the rotation speed of the output shafts of the drive motors 10 allows for a speed difference between the grinding rollers 5 in the same group. This results in greater shearing force on the material as it passes through the grinding rollers 5, which is beneficial for grinding the material.

[0027] like Figure 1-3As shown, in a further preferred embodiment, the liquid discharge structure includes a discharge pipe 11 and a control valve. The discharge pipe 11 has a C-shaped structure, and its ends are fixedly connected to corresponding mixing chambers. The control valve is mounted on the corresponding discharge pipe 11 and is a solenoid valve. The solenoid valve can be connected to a PLC controller for easy control. By adjusting the control valve on the discharge pipe 11, the liquid in the upper mixing chamber can be controlled to flow downwards for further processing.

[0028] like Figure 1-3 As shown, in a further preferred embodiment, the spraying device includes several spray pipes 12 and several spray nozzles 13. The spray pipes 12 are respectively disposed in the upper part of the mixing chamber, and the spray nozzles 13 are respectively fixedly installed at the bottom of the spray pipes 12 and evenly distributed. The spray nozzles 13 are interconnected with the spray pipes 12. Damping valves are sequentially installed from top to bottom on the inlet pipe 6 and the movable pipe 8, with the damping of the damping valves increasing sequentially from top to bottom, thereby preventing water from escaping only from the lower spray pipes 12. One end of each spray pipe 12 is fixedly connected to the movable pipe 8 and interconnected, while the other end of the spray pipe 12 is sealed. Water in the movable pipe 8 can be sprayed out along the spray pipes 12. In addition, the rotation of the movable pipe 8 can drive the spray pipes 12 and the spray nozzles 13 to rotate, thereby increasing the spraying range of the spray nozzles 13 and facilitating the mixing of materials.

[0029] like Figure 1-3 As shown, in a further preferred embodiment, the stirring device includes several impellers 14, a sealing groove plate 15, and a transmission gear set. The bottom surface of the sealing groove plate 15 has a sealing groove. The transmission gear set includes a driving gear and several driven gears. The sealing groove plates 15 are respectively fixedly installed on the bottom surface of the mixing chambers. The movable tube 8 passes through the sealing groove plate 15 and is rotatably connected. The transmission gear set is located inside the sealing groove. The driving gear is fixedly installed on the outer periphery of the movable tube 8. The impellers 14 are evenly distributed in their respective mixing chambers. The mounting shaft of the impeller 14 passes through the top surface of the sealing groove plate 15 and is rotatably connected. The driven gears are respectively fixedly installed at the lower end of the mounting shaft of the corresponding impeller 14. The driven gears mesh with the corresponding driving gears. The rotational speeds in the three mixing chambers are different, which can be controlled by the transmission ratio of the transmission gear combination. The impeller 14 in the upper mixing chamber rotates at 20–35 rpm, the impeller 14 in the middle mixing chamber rotates at 35–50 rpm, and the impeller 14 in the lower mixing chamber rotates at 20–30 rpm. Since the rotational speed of the spray pipe 12 is much lower than that of the impeller 14, it can be replaced with a multi-stage acceleration gear structure, thereby preventing the spray pipe 12 from rotating too fast. The rotation of the movable pipe 8 can drive the impeller 14 to rotate through the transmission gear set, so that the impeller 14 can stir and mix the material. This stirring device has a simple structure and is easy to use.

[0030] like Figure 1-3As shown, in a further preferred embodiment, the rotating device is a rotating motor 16. The rotating motor 16 is an industrial servo motor, which can be controlled by a servo control system. This facilitates control of the output shaft speed of the rotating motor 16. The control board can control both the industrial servo motor and the solenoid valve, thereby achieving electrical automation. The rotating motor 16 is fixedly installed on the bottom surface of the mixing tank 2. Support legs are fixedly installed at the four corners of the bottom surface of the mixing tank 2. The output shaft of the rotating motor 16 passes through the bottom surface of the mixing tank 2 and is sealed and rotatably connected. The output shaft of the rotating motor 16 is fixedly connected to the lower end of the movable tube 8. When the rotating motor 16 is turned on, its output shaft can drive the movable tube 8 to rotate. This rotating device has a simple structure and is easy to use.

[0031] like Figure 1-3 As shown, in a further preferred embodiment, the feeding device includes a mounting plate, a feeding hopper 17, a feeding pipe 18, and a regulating valve. The regulating valve operates using an electric proportional valve with a metering feedback module, controlled by an existing control motherboard to control the amount of additive added. The mounting plate is fixedly installed on the other side of the mixing chamber 2, the feeding hopper 17 is fixedly installed on the top surface of the mounting plate, the upper end of the feeding pipe 18 penetrates the mounting plate and is fixedly connected to the feeding hopper 17, and the regulating valve is located on the feeding pipe 18. The lower end of the feeding pipe 18 penetrates the other side of the mixing chamber 2 and is connected to the upper part of the central mixing chamber. When the additive is added to the feeding hopper 17 and the regulating valve is opened, the material can enter the central mixing chamber along the feeding pipe 18, thereby performing feeding and mixing.

[0032] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
