The crusher 2 and mixer 5 are located on the ground 1, a support frame, or a factory building, etc., and this application takes the location on the ground 1 as an example; the ground 1 refers to the ground of the construction area; a conveyor 3 is provided between the crusher 2 and the mixer 5; the crusher 2 is used to crush phosphogypsum, and existing crushing equipment can be used, such as an impact crusher, and the conveyor 3 is preferably a belt conveyor, used to send the crushed phosphogypsum into the interior of the mixer 5.

[0054] The top of the support platform 4 is equipped with several storage tanks 6; the storage tanks 6 store cement and liquid or solid curing agent. The solid curing agent includes powders such as lime, mineral powder, silica fume, and fly ash. The cement and solid curing agent are fed by a sealed screw conveyor. Crushed sand and gravel can also be stored as needed. When in use, the mixed cement, solid curing agent, and crushed sand and gravel (possibly) are added to the mixer 5 and mixed with phosphogypsum to obtain the corresponding product. Then, it is transported away by a material transport vehicle. The operation is simple and easy to mix.

[0055] Storage tank 6 is connected to mixer 5 via feed pipe 601. Feed pipe 601 is configured according to the type of material being conveyed. For example, sand and gravel are conveyed via belt conveyor, while cement is conveyed via screw conveyor or pump. The specific configuration depends on the actual conveying situation. When using pump, cement and water are pre-mixed. Furthermore, both conveyor 3 and feed pipe 601 are equipped with sensors to detect the amount of material being fed in. Existing weight sensors, such as weight sensors or flow sensors, are used, depending on actual needs. Alternatively, sensors may not be required.

[0056] Furthermore, the bottom of the support platform 4 is provided with an operating trough 401, the storage tank 6 is arranged adjacent to the mixer 5, and the ground 1 is provided with a groove, allowing transport vehicles to drive into the operating trough 401 to collect the mixed phosphogypsum base mixture from the bottom of the mixer 5. The support platform 4 also constitutes a protective facility for transport vehicles, ensuring safety during operation.

[0057] In a further embodiment, such as Figure 1 , 2 As shown in Figure 4, the mixer 5 includes a mixing tank 501; a conveyor 3 and a feed pipe 601 are connected to the mixing tank 501; the bottom of the mixing tank 501 is provided with a discharge pipe 502 and several support legs 503; the top of the mixing tank 501 is provided with a baffle 504; the mixing tank 501 is provided with several mixing mechanisms 8, wherein the mixing mechanism 8 includes a mixing rod 801, the mixing rod 801 is provided with several mixing blades 802, the mixing blades 802 are located inside the mixing tank 501, and the mixing blades 802 are the mixing and flow-promoting blades used for forced mixing in the prior art;

[0058] Preferably, the mixing tank 501 adopts a horizontal structure. A motor 803 is provided on the side of the mixing tank 501. The motor 803 is an existing motor that can be controlled to rotate in both directions. It is connected and controlled in an existing manner. The output shaft of the motor 803 is provided with a drive wheel 804. The end of the mixing rod 801 is provided with a driven wheel 805. The driven wheel 805 is located on the side of the mixing tank 501. The driven wheel 805 and the drive wheel 804 are connected by a first belt 806. The diameter of the driven wheel 805 is larger than the diameter of the drive wheel 804.

[0059] When in use, the starter motor 803 drives the drive wheel 804 to rotate, which in turn drives the driven wheel 805 to rotate via the first belt 806, thereby driving the mixing rod 801 and the mixing blade 802 to rotate, thus forcibly mixing the materials in the mixing tank 501.

[0060] Example 2:

[0061] like Figure 2 , 3 As shown in Figures 4, 5, and 6, a spraying mechanism 7 is provided inside the baffle 504 at the top of the mixing tank 501. The spraying mechanism 7 is used to spray water mist or liquid curing agent into the mixing tank 501. The water mist is used to adjust the water content of the phosphogypsum base mixture.

[0062] The spraying mechanism 7 includes a rotating pipe 701 located on the top of the partition 504, and the rotating pipe 701 is arranged horizontally.

[0063] The rotating tube 701 is provided with several protective sleeves 702, which extend to the bottom of the partition 504 and are sealed at the connection between the protective sleeves 702 and the partition 504; the protective sleeves 702 are provided with openings 703; the rotating tube 701 is provided with several branch pipes 704, each branch pipe 704 is provided with a nozzle 705, which is located inside the opening 703; in use, water or liquid curing agent enters the rotating tube 701 and is sprayed out through the nozzle 705 at the end of the branch pipe 704, and then sprayed out through the opening 703.

[0064] In another alternative embodiment, the rotating pipe 701 is rotatably connected to the mixing tank 501, and a bearing is provided at the connection point; one end of the rotating pipe 701 is sealed, and the other end is provided with a liquid inlet pipe 707 through a rotary joint 708; the liquid inlet pipe 707 is connected to an external liquid source, such as water with a water pump and a liquid curing agent storage tank, and the liquid inlet pipe 707 is fixedly connected to the mixing tank 501 through a fixing bracket 706; the liquid inlet pipe 707 is provided with a valve 709, which is preferably a solenoid valve; the rotating pipe 701 is drivenly connected to the mixing rod 801. In use, the rotating pipe 701 is first driven to rotate by the mixing rod 801, so that the opening 703 faces downward. Then, the valve 709 is opened, and water or liquid curing agent is sprayed out through the nozzle 705 after passing through the liquid inlet pipe 707, the rotary joint 708, the rotating pipe 701 and the branch pipe 704 in sequence. This allows for the addition of liquid to the material being mixed. Preferably, the liquid inlet pipe 707 can be equipped with a three-way connector, which connects to two external pipes with valves. The two external pipes are respectively connected to the water source and the liquid curing agent storage.

[0065] In a further embodiment, the transmission connection structure between the rotating tube 701 and the mixing rod 801 includes a passive wheel 808 fixedly connected to the rotating tube 701; the mixing rod 801 is provided with a transmission wheel 807, and the passive wheel 808 and the transmission wheel 807 are connected by a second belt 809; during the transmission process, the rotation of the mixing rod 801 drives the transmission wheel 807 to rotate, thereby driving the passive wheel 808 to rotate through the second belt 809, and finally driving the rotating tube 701 to rotate.

[0066] Furthermore, the passive wheel 808 has a guide groove 881 on its side, and the mixing tank 501 has a guide block 882 on its side. The guide block 882 is slidably connected to the inside of the guide groove 881. The guide groove 881 is an arc-shaped groove and is coaxial with the rotating tube 701. During the rotation of the passive wheel 808, the guide block 882 slides in the guide groove 881 and stops at the end of the guide groove 881, thereby limiting the rotation range of the passive wheel 808. Preferably, when the guide block 882 is located at one end of the guide groove 881, the opening 703 faces downward, and when the guide block 882 is located at the other end of the guide groove 881, the opening 703 faces upward. When the opening faces upward, it can protect the nozzle 705 and prevent the nozzle 705 from being contaminated with the mixed material. When the opening faces downward, water or liquid curing agent can be sprayed into the mixing tank 501 through the nozzle 705 to adjust the humidity of the material.

[0067] In a further embodiment, the transmission wheel 807 includes a fixed sleeve 871 fixedly sleeved outside the mixing rod 801, the fixed sleeve 871 being located outside the mixing tank 501; a rotating sleeve 872 is rotatably sleeved around the outer periphery of the fixed sleeve 871, and a plurality of rolling balls 873 are provided between the rotating sleeve 872 and the fixed sleeve 871; a plurality of radially arranged connecting holes are provided inside the rotating sleeve 872, and a threaded hole is provided at one end of the connecting hole near the outer periphery of the rotating sleeve 872, and a connecting block 874 is threadedly connected thereto; a movable block 876 is slidably connected to the other end of the connecting hole, and a spring 875 is provided between the movable block 876 and the connecting block 874; a friction block 877 is provided on the side of the movable block 876 away from the spring 875, and the friction block 877 abuts against the fixed sleeve 871; the spring 875 is in a compressed state, and the force provided by the spring 875 is sufficient to allow the friction block 877 to abut against the fixed sleeve 871, thereby generating friction.

[0068] When the mixing rod 801 rotates, it drives the fixed sleeve 871 to rotate. The fixed sleeve 871 drives the friction block 877 to rotate through friction, which in turn drives the rotating sleeve 872 to rotate. This, in turn, drives the second belt 809 to rotate, and finally drives the driven wheel 808 to rotate, so as to achieve the purpose of adjusting the nozzle 705.

[0069] After rotating to the limit position, the guide block 882 abuts against the end of the guide groove 881, and the driven wheel 808, the second belt 809 and the rotating sleeve 872 stop rotating. The rotating sleeve 872 and the fixed sleeve 871 rotate relative to each other without affecting the mixing. When the nozzle 705 needs to be rotated to another position, the reverse motor 803 can be reversed. The operation is simple, easy to adjust, and does not affect the mixing of materials.
