[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a phosphogypsum conveying system, such as Figure 1-Figure 3As shown, it includes a feed hopper 1, a plate feeder 2 is installed on one side of the feed hopper 1, a conveyor 3 is arranged at one end of the plate feeder 2, the conveyor 3 is inclined, an iron-absorbing device 4 is connected to the top of the conveyor 3, a hammer crusher 5 is installed at one end of the iron-absorbing device 4, a discharging belt 6 is arranged at the lower part of the hammer crusher 5, the conveyor 3 includes a horizontal belt 31, a material-blocking belt 32 is arranged on both sides of the horizontal belt 31, a roller 33 is arranged below the material-blocking belt 32, and the roller 33 is supported and fixed by a bracket 34. The feed hopper 1 is the starting part of the whole system, which is responsible for receiving and temporarily storing phosphogypsum. Its design allows the phosphogypsum to smoothly enter the subsequent transportation and processing links. The top of the feed hopper is provided with a feed port to facilitate the input of phosphogypsum; the bottom is provided with a discharge port, which is connected to the plate feeder 2 to ensure that the phosphogypsum can be uniformly and continuously supplied to the subsequent equipment. The plate feeder 2 is installed on one side of the feed hopper 1. Its main function is to uniformly and continuously transport the phosphogypsum from the feed hopper to the conveying device 3. Driven by the motor, the plate feeder can efficiently complete this task to ensure that the phosphogypsum will not be blocked or interrupted during the transportation process. The horizontal belt 31 is the main bearing part of the phosphogypsum, and the retaining belt 32 is set on both sides of the horizontal belt to prevent the phosphogypsum from scattering or flying during the transportation process. The roller 33 and the bracket 34 jointly support the entire conveying device to ensure its stable operation. The hammer crusher 5 is installed at one end of the magnetic device 4. Its function is to crush the phosphogypsum after the magnetic treatment. Since there may be some large particles in the phosphogypsum, if these materials are not crushed, they may block the subsequent equipment or affect the production quality. Hammer crushers can effectively crush these large particles into the required particle size, ensuring the smooth transportation and processing of phosphogypsum.

[0023] In this embodiment, the magnetic device 4 includes a shell 41, a conveyor belt 42 is arranged inside the shell 41, a magnet 43 is installed above the inside of the shell 41, and the magnetic device 4 is connected to the top of the conveyor 3. Its main function is to remove the magnetic substances in the phosphogypsum. If these magnetic substances are not removed in time, they may cause damage to subsequent equipment or affect production efficiency. The magnetic device is provided with a conveyor belt and a magnet inside. When the phosphogypsum passes by, the magnetic substances will be adsorbed by the magnet and removed from the system along with the conveyor belt.

[0024] Specifically, the plate feeder 2 and the conveying device 3 are both driven by motors to facilitate stable conveyance of materials.

[0025] Furthermore, a feed port 13 is provided at the top of the feed hopper 1 , a discharge port 16 is provided at the bottom of the feed hopper 1 , and supporting legs 17 are installed at the bottom of both sides of the feed hopper 1 .

[0026] Furthermore, a screen 11 is obliquely installed inside the feed hopper 1, and one end of the screen 11 is driven to vibrate by a vibration motor 12, so as to facilitate the screening of impurities in the material.

[0027] Furthermore, a large particle discharge pipe 14 is installed on one side of the feed hopper 1, and a valve 15 is installed on the large particle discharge pipe 14 to facilitate the discharge of impurities.

[0028] Furthermore, a roller shaft 331 is provided in the middle of the roller 33 , a vertical plate is installed on the top of the bracket 34 , and both ends of the roller shaft 331 are fixed on the vertical plate to facilitate the transmission of the horizontal belt 31 and the blocking belt 32 .

[0029] Furthermore, the feed port of the hammer crusher 5 is connected to the output end of the conveyor belt 42, and the discharge port of the hammer crusher 5 is located at the upper part of one end of the discharge belt 6, which is convenient for material transmission.

[0030] When the phosphogypsum conveying system of the utility model is used, first, the phosphogypsum is put into the feed hopper 1 through the feed port 13 and enters the feed hopper. The screen 11 installed obliquely inside the feed hopper vibrates under the drive of the vibration motor 12 to perform preliminary screening of the phosphogypsum to remove impurities and large particles therein. The screened phosphogypsum falls into the plate feeder 2 evenly and continuously through the discharge port 16.

[0031] Driven by the motor, the plate feeder 2 evenly conveys the phosphogypsum to the inclined conveyor 3. The conveyor 3 consists of a horizontal belt 31, a material-blocking belt 32, a roller 33 and a bracket 34. The horizontal belt 31 is the main bearing part of the phosphogypsum, and the material-blocking belt 32 is arranged on both sides of the horizontal belt to prevent the phosphogypsum from scattering or flying during the conveying process. The roller 33 and the bracket 34 jointly support the entire conveyor to ensure its stable operation. Under the action of the conveyor, the phosphogypsum is smoothly conveyed to the magnetic device 4.

[0032] The magnetic device 4 includes a housing 41, a conveyor belt 42 and a magnetic stone 43. When the phosphogypsum passes through the magnetic device, the magnetic material therein is adsorbed by the magnetic stone 43 and moves out of the system along with the conveyor belt 42, thereby ensuring the normal operation and production efficiency of subsequent equipment.

[0033] After the iron absorption treatment, the phosphogypsum enters the hammer crusher 5. The hammer crusher crushes the phosphogypsum and crushes the large particles into the required particle size. The crushed phosphogypsum falls onto the discharge belt 6 through the discharge port of the hammer crusher and is smoothly transported to the outside of the system or the next processing link.

[0034] Finally, it should be noted that the electronic components in the hammer crusher 5 in this embodiment are all universal standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components are connected by wires respectively, and the specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the art.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
