DETAILED DESCRIPTION

[0017] The following is combined with Figure 1-2 The specific implementation modes of the present invention are further described in detail.

[0018] When the present invention is actually implemented, Figure 1-2A phosphogypsum batching machine includes a bracket 1, on which a silo 2 is fixedly mounted. In actual use, the batching machine needs to measure the phosphogypsum and put it on a belt conveyor for transportation to complete the batching. Therefore, the bracket 1 is set up to place the silo 2 above the belt conveyor. An adjusting material door 4 is installed at the bottom of the silo 2 to control the opening degree of the adjusting material door 4 to achieve accurate control of the material flow rate. Specifically, in order to facilitate the control of the discharge flow rate, a discharge channel 3 is provided at the lower end of the silo 2, and the adjusting material door 4 is cooperatively arranged at the discharge channel 3. A belt scale 5 is installed on the silo 2 and is placed below the adjusting material door 4. In this embodiment, the type of the belt scale 5 is not specifically limited. Those skilled in the art can select it according to actual needs, and it can achieve stable metering of the phosphogypsum flowing out of the silo 2. At the same time In the present embodiment, a certain gap is left between the belt scale 5 and the discharge channel 3. After the phosphogypsum is added into the silo body 2, it will fall directly onto the belt scale 5. After the belt scale 5 is started, the phosphogypsum material will be driven by the belt scale 5 to be delivered to the belt conveyor, and the amount of phosphogypsum delivered is determined by the weight difference detected by the belt conveyor. Therefore, in the present embodiment, the adjusting material gate 4 essentially plays a blocking role, and the discharge flow rate of the phosphogypsum material is controlled by controlling the height of the adjusting material gate 4 from the belt scale 5. Specifically, the adjusting material gate 4 is rotatably matched with a screw 17, and the screw 17 is threadedly connected to the screw sleeve installed on the silo body 2, so that the adjusting material gate 4 can be driven to move by rotating the screw 17, thereby controlling the height of the adjusting material gate 4 from the belt scale 5, and realizing uniform and stable delivery of the phosphogypsum material.

[0019] A plurality of folding panels 6 mounted on the bracket 1 are arranged above the warehouse body 2, and the folding panels 6 are all hinged on the bracket 1. When the folding panels 6 need to be erected, adjacent folding panels 6 are fixedly connected by bolts, thereby realizing a circle of panels with a blocking effect above the warehouse body 2. When the batching machine is transported, after the bolts on the folding panels 6 are removed, the folding panels 6 will be rotated downward and folded, so as to facilitate the transportation of the batching machine.

[0020] A screening device is arranged in the folding enclosure 6, that is, a screening device is arranged at the feeding end of the bin body 2, so as to prevent large pieces of material from entering the batching machine and causing damage to the equipment. Specifically, the screening device includes a vibration grille 7 hinged on the bracket 1, and an exciter 8 and a buffer device are installed on the vibration grille 7. After the exciter 8 is started, the vibration grille 7 will vibrate to meet the requirements of filtering out large pieces of material through the vibration of the vibration grille 7, so as to ensure that the material entering the batching machine meets the requirements. At the same time, in this embodiment, the vibration grille 7 can also adjust the vibration frequency and amplitude according to the material characteristics to improve the screening efficiency. The surrounding folding enclosure 6 can block the vibration. The large pieces of material on the vibrating grille 7 fall to the surroundings. After completing a phosphogypsum filling, the staff can remove the large pieces of material from the vibrating grille 7. In this embodiment, a buffer device structure is provided. The buffer device includes a base 9 fixedly mounted on the bracket 1. A guide rod 10 is arranged in the base 9. A spring 11 installed in the base 9 is sleeved on the guide rod 10. The other end of the spring 11 is installed on the vibrating grille 7 to meet the requirement that the spring 11 provides supporting elastic force to the vibrating grille 7. When the vibrating grille 7 is driven by the exciter 8 to vibrate around its hinge axis, the spring 11 supports and pulls back the vibrating grille 7 to ensure stable vibration of the vibrating grille 7.

[0021] In the present embodiment, after the phosphogypsum is loaded into the silo 2, an arching phenomenon will occur because the phosphogypsum is in powder form, thereby affecting the feeding and causing blockage. By default, a stirring arch-breaking device is provided inside the silo 2, and internal conduction vibration arch-breaking devices installed inside the silo 2 are provided on both sides of the stirring arch-breaking device. The internal conduction arch-breaking device is used in conjunction with the stirring arch-breaking device to further improve the fluidity of the phosphogypsum material and ensure the stability of the batching machine operation. Specifically, the stirring arch-breaking device includes a stirring shaft 12 rotatably installed on the silo 2, and a plurality of stirring blades 13 are arranged at intervals on the stirring shaft 12. The stirring shaft 12 is driven to rotate by a driving motor installed on the bracket 1, and the rotation of the stirring shaft 12 will drive the stirring blades 13 to forcibly stir the phosphogypsum material in the silo 2, thereby destroying the internal friction and adsorption between the phosphogypsum particles, thereby improving the fluidity of the phosphogypsum material and preventing The phosphogypsum material is accumulated to form an arch structure, and the internal conduction arch breaking device includes an arch breaking plate 16 hinged in the silo 2. The arch breaking plate 16 is equipped with an exciting motor installed outside the silo 2, so that after the exciting motor is started, the exciting force will be transmitted to the side wall of the silo 2. Under the action of the exciting force, the arch breaking plate 16 will vibrate at high frequency around its hinge axis, thereby ensuring that the exciting force is transmitted to the phosphogypsum material at the edge of the side wall of the silo to avoid arching between the phosphogypsum materials. In this embodiment, the stirring arch breaking device runs through the entire silo 2, so as to solve the arching of the material in the middle part of the silo 2 to the greatest extent. However, because the stirring shaft 12 only has a rotating function, the material at the side wall of the silo 2 cannot be affected by the stirring arch breaking device. By setting the internal conduction arch breaking device, the phosphogypsum material at the edge will be excited, the inefficient area of ​​the stirring arch breaking device is eliminated, and the stability of the batching machine is ensured.

[0022] It is preset that in the present embodiment, because the stirring shaft 12 passes through the entire silo body 2, a sealing structure needs to be provided between the stirring shaft 12 and the side wall of the silo body 2 to prevent the phosphogypsum material from overflowing from between the silo body 2 and the stirring shaft 12. Specifically, in order to facilitate the movement and sealing of the stirring shaft 12, a support seat 14 is installed outside the silo body 2, and the stirring shaft 12 is rotatably installed on the support seat 14, that is, the stirring shaft 12 is supported by the support seat 14, and a sealing structure is provided between the stirring shaft 12 and the side wall of the silo body 2. The sealing structure includes a sleeve 15 installed on the silo body 2, and at least one sealing ring is installed in the sleeve 15, so that when the stirring shaft 12 rotates, the sleeve 15 and the sealing ring do not rotate, so that the phosphogypsum material can be prevented from overflowing through the sealing ring without interfering with the rotation of the stirring shaft 12.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
