[0002] High-tower compound fertilizer is a granular fertilizer produced by high-tower granulation process. In its production process, preparing a slurry with good fluidity is one of the key technologies. This requires grinding the slurry before the granulation process. Horizontal grinding equipment is usually used for grinding.

[0003] A search revealed, for example, a utility model with publication number CN216172857U, which discloses a horizontal grinding device for high-tower compound fertilizer. The device has an output mechanism for driving the grinding mechanism mounted on its housing, and a discharge pipe connected to the bottom of the housing. The grinding mechanism includes a rotating support shaft passing through one end of the housing, with a grinding roller connected to one end of the shaft. The grinding roller is located inside the housing. This utility model discharges the ground compound fertilizer through the discharge pipe at its bottom. During discharge, the ground material inside the device may be in a loose state, especially in the fine powder portion, which easily generates dust. This dust overflows with the compound fertilizer during discharge, easily causing dust pollution in the working environment. Therefore, to solve the above defects, the inventor proposes a horizontal grinding device for high-tower compound fertilizer. Utility Model Content

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] This utility model discloses a horizontal grinding device for high-tower compound fertilizer, such as... Figure 1-6 As shown, it includes a grinding tank 1 and a fan 4 located at the bottom of the grinding tank 1. The motor drives the impeller to rotate at high speed. The center of the impeller forms a low-pressure area due to the rotation, which forms a pressure difference with the atmospheric pressure outside the air inlet. Under the action of the pressure difference, the external gas enters the central area of ​​the impeller evenly through the air inlet.

[0016] The high-speed rotating impeller blades exert centrifugal force on the incoming gas, simultaneously increasing the gas's kinetic and pressure energy. As the impeller rotates, the gas moves from the center to the edge, increasing the flow velocity from a low speed at the center to a high speed at the edge.

[0017] After the high-speed airflow enters the casing, the spiral flow channel of the casing guides the airflow. The pressurized gas is discharged from the outlet and enters the discharge pipe 101 to transport the ground compound fertilizer material.

[0018] Because the actual application scenarios are different, the type of fan 4 used is also different, so we will not limit the fan 4 here. Also, since the fan 4 is a mature technology, we will not elaborate on it.

[0019] A discharge pipe 102 with a valve is fixedly installed on the bottom surface of the grinding tank 1, and a discharge pipe 101 is fixedly installed at the bottom end of the discharge pipe 102. When the valve of the discharge pipe 102 is opened, the compound fertilizer ground inside the grinding tank 1 enters the discharge pipe 101 through the discharge pipe 102.

[0020] A filter cylinder 104 is fixedly installed on one side of the outer surface of the grinding tank 1, and a dust removal bag 1041 is provided inside the filter cylinder 104. A transmission pipe 103 is fixedly connected between the inlet of the fan 4 and the filter cylinder 104, and the outlet of the fan 4 is fixedly connected to the discharge pipe 101. A fixing pipe 105 is fixedly connected between the filter cylinder 104 and the grinding tank 1.

[0021] When the blower 4 is running, the dust generated inside the grinding tank 1 due to grinding enters the filter cylinder 104 through the fixed pipe 105. The dust collector bag 1041 can filter the dust-laden air to intercept the dust. The filtered air can then enter the blower 4 through the transmission pipe 103 and enter the discharge pipe 101 from the outlet of the blower 4, pushing the compound fertilizer inside the discharge pipe 101 to move and complete its discharge.

[0022] An installation ring 1042 is fixedly installed on the top surface of the dust collector bag 1041, and a connecting plate 1043 is fixedly installed on the inner top surface of the filter cartridge 104. The connecting plate 1043 is threadedly connected to the installation ring 1042. The installation ring 1042 is made of stainless steel, and its inner wall is provided with threads that match the connecting plate 1043. The threaded connection between the installation ring 1042 and the connecting plate 1043 facilitates the disassembly or installation of the dust collector bag 1041.

[0023] The bottom end of the filter cartridge 104 is provided with a bottom cover 1044. The bottom cover 1044 is fixedly connected to the bottom end of the filter cartridge 104 by bolts. The bottom cover 1044 can be separated from the filter cartridge 104 by simply removing the bolts on the bottom cover 1044, and then the dust collector bag 1041 can be installed or removed.

[0024] Two feed pipes 2 are fixedly installed on the top surface of the grinding tank 1. Inclined guide plates 201 are fixedly installed on both sides of the inner wall of the feed tank. Rotating shafts 204 are fixedly installed on both sides of the inside of the feed pipes 2. Protective plates 203 are rotatably connected to the outer surfaces of the two rotating shafts 204. The two guide plates 201 are inclined towards the direction between the two protective plates 203. When the worker pours the compound fertilizer to be ground, the compound fertilizer can fall accurately into the position between the two protective plates 203.

[0025] Both sides of the inside of the feed pipe 2 are fixedly installed with baffles 202, and the two baffles 202 contact the two protective plates 203 respectively. Both sides of the inside of the feed pipe 2 are provided with two torsion springs 205, and the four torsion springs 205 are respectively sleeved on the outer ends of the two rotating shafts 204 and fixedly connected to the two protective plates 203. Through the torsion springs 205, the two protective plates 203 will abut against the two baffles 202 in the normal state.

[0026] When the compound fertilizer falls precisely between the two protective plates 203, the weight of the compound fertilizer will overcome the elastic force of the torsion spring 205, thereby causing the two protective plates 203 to rotate away from the stop bar 202, and the compound fertilizer can fall into the grinding tank 1 through the gap between the two protective plates 203.

[0027] The grinding tank 1 is rotatably connected to a rotating rod 1011. Multiple striking rods 1012 are fixedly installed on both sides of the outer surface of the rotating rod 1011. A grinding block 1013 is fixedly installed in the middle of the outer surface of the rotating rod 1011. When the rotating rod 1011 rotates, it can drive the multiple striking rods 1012 and the grinding block 1013 to rotate.

[0028] The compound fertilizer falling from the feed pipe 2 will first fall into the area of ​​the striking rod 1012, which can strike the compound fertilizer to effectively break up the large particles in the compound fertilizer.

[0029] After being struck, the compound fertilizer will gradually slide along the inner wall of the grinding tank 1 towards the area of ​​the grinding block 1013, and the rotating grinding block 1013 can grind the compound fertilizer.

[0030] A geared motor 3 is fixedly installed on one side of the outer surface of the grinding jar 1. One end of the rotating rod 1011 extends to the outside of the grinding jar 1 and is fixedly connected to the output shaft of the geared motor 3.

[0031] The motor of the geared motor 3 is connected to the power supply. The input shaft of the reducer and the output shaft of the motor are connected by a coupling. After the motor is powered on, the stator winding generates a rotating magnetic field. The rotor rotates following the magnetic field due to electromagnetic induction, outputting high-speed rotational power. The reducer reduces the motor speed through gear meshing and amplifies the torque by utilizing the speed ratio relationship of "large wheel leading small wheel". The output shaft of the reducer transmits the reduced low-speed, high-torque power to the rotating rod 1011, driving the rotating rod 1011 to drive the grinding block 1013 to rotate at low speed, completing operations such as compound fertilizer grinding.

[0032] The working principle of this utility model is as follows: The worker first starts the reduction motor 3, drives the rotating rod 1011 to drive the grinding block 1013 and multiple striking rods 1012 to rotate. Then the worker pours the compound fertilizer to be ground into the two feed pipes 2. The two guide plates 201 enable the poured compound fertilizer to fall accurately between the two protective plates 203.

[0033] The weight of the compound fertilizer will overcome the elastic force of the torsion spring 205, thereby causing the two protective plates 203 to rotate to the side away from the stop bar 202, and the compound fertilizer can fall into the grinding tank 1 through the gap between the two protective plates 203.

[0034] The compound fertilizer falling from the feed pipe 2 will first fall into the area of ​​the striking rod 1012. The striking rod 1012 can strike the compound fertilizer to effectively break down the large particles in the compound fertilizer. After being struck, the compound fertilizer will gradually slide along the inner wall of the grinding tank 1 towards the area of ​​the grinding block 1013. The rotating grinding block 1013 can then grind the compound fertilizer.

[0035] An external container, such as a storage bag, is placed over the opening of the discharge pipe 101. Then, the valve of the discharge pipe 102 is opened, allowing the compound fertilizer ground inside the grinding tank 1 to enter the discharge pipe 101 through the discharge pipe 102. The blower 4 is running, and the dust generated inside the grinding tank 1 due to grinding enters the filter cartridge 104 through the fixed pipe 105. The dust collector bag 1041 can filter the dust-laden air to intercept the dust. The filtered air can then enter the blower 4 through the transmission pipe 103 and enter the discharge pipe 101 from the outlet of the blower 4, pushing the compound fertilizer inside the discharge pipe 101 to move and complete its discharge.
