Description

Technical Field

[0001] The utility model relates to a new type of biomass nutrient pellet production system. Background Art

[0002] Phosphogypsum is an industrial waste discharged from the wet-process phosphoric acid process. Generally, 4 - 4.5 tons of phosphogypsum will be produced for every 1 ton of wet-process phosphoric acid produced. The large-scale stacking of phosphogypsum not only easily causes environmental pollution and wastes land resources, but also it is difficult to recycle phosphogypsum itself, resulting in a heavy burden on phosphate chemical enterprises and poor economic benefits. Therefore, it is necessary to seek reasonable utilization ways of phosphogypsum to achieve the sustainable development of the phosphate fertilizer industry and the high utilization of phosphogypsum. Content of the Utility Model

[0003] The purpose of the utility model is to provide a new type of biomass nutrient pellet production system, which can prepare phosphogypsum into biomass granular fertilizer to realize the recycling of phosphogypsum.

[0004] To solve the above problems, the technical solution of the utility model is as follows:

[0005] A new type of biomass nutrient pellet production system includes a frame. A first conveyor is installed on the frame. Above the first conveyor, a plurality of hoppers are installed on the frame. A first discharger is installed at the lower end of the hopper. The discharge end of the first conveyor is connected to the feed end of the second conveyor. The discharge end of the second conveyor is connected to the feed end of the double-shaft stirring conveyor. The discharge end of the double-shaft stirring conveyor is connected to the feed port of the pellet forming machine. The discharge port of the pellet forming machine is connected to the feed end of the third conveyor.

[0006] A belt scale is connected between the first discharger and the first conveyor.

[0007] A nutrient agent adding hopper is provided at the discharge end of the first conveyor, and a second discharger is connected to the lower end of the nutrient agent adding hopper.

[0008] An infusion pipe for pellet forming is communicated with the double-shaft stirring conveyor, and a flow meter and a flow regulating valve are installed on the infusion pipe.

[0009] It further includes a PLC controller. The weighing sensors in the flow meter and the electronic belt scale are connected to the input end of the PLC controller. The drive motors in the first discharger, the second discharger, the flow regulating valve and the electronic belt scale are connected to the output end of the PLC controller.

[0010] Three hoppers are installed on the frame, which are phosphogypsum hopper, organic fertilizer hopper and nutrient soil hopper respectively.

[0011] The beneficial effects of the present utility model are as follows: Qualified phosphogypsum, organic fertilizer, nutrient soil, etc. are proportioned, stirred and granulated into biomass fertilizers, and processed into pellets (there are large gaps between the pellets to facilitate the grass seeds to obtain nutrients and grow), which can well grow various flowers and plants. It can be widely applied to the revegetation of various slag yards, and can also be used for the greening of urban squares and flower beds. This not only solves the application problem of phosphogypsum, but also turns waste into treasure and uses it as a plant growth fertilizer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] As Figure 1 shown, a new type of biomass nutrient pellet production system includes a frame 1, on which a first conveyor 14 is installed. Above the first conveyor 14, three hoppers 2 are installed on the frame 1. The three hoppers 2 are a phosphogypsum hopper 2, an organic fertilizer hopper 2, and a nutrient soil hopper 2 respectively. A first discharger 4 is installed at the lower end of the hopper 2. The discharge end of the first conveyor 14 is connected to the feed end of the second conveyor 7, the discharge end of the second conveyor 7 is connected to the feed end of the double-shaft stirring conveyor 13, the discharge end of the double-shaft stirring conveyor 13 is connected to the feed port of the pellet forming machine 12, and the discharge port of the pellet forming machine 12 is connected to the feed end of the third conveyor 11. The first conveyor 14, the second conveyor 7, and the third conveyor 11 are all belt conveyors.

[0018] A belt scale 3 is connected between the first unloader 4 and the first conveyor 14. The phosphogypsum, organic fertilizer, and nutrient soil are weighed and conveyed by the electronic belt scale 3, so that the phosphogypsum, organic fertilizer, and nutrient soil can be fed into the pellet forming machine 12 according to the set ratio to make biomass pellet fertilizer.

[0019] A nutrient agent adding hopper 5 is provided at the discharge end of the first conveyor 14, and a second unloader 6 is connected to the lower end of the nutrient agent adding hopper 5. Through the nutrient agent adding hopper 5, nutrient agents with a relatively small proportion can be mixed into the pellet fertilizer, such as rooting agents, gibberellins, etc. In addition, the rotation speed of the second unloader 6 is controlled by a frequency converter 16 to control the addition amount of the nutrient agent.

[0020] A liquid infusion pipe 9 is connected to the double-shaft stirring conveyor 13, and a flow meter 10 and a flow regulating valve 8 are installed on the liquid infusion pipe 9. In order to make the phosphogypsum, organic fertilizer, and nutrient soil agglomerate, a certain amount of water or gelling agent is pumped into the double-shaft stirring conveyor 13 through the liquid infusion pipe 9. During the conveying process, the flow meter 10 measures the flow rate in real time, and at the same time, under the adjustment of the flow regulating valve 8, the water or gelling agent can be added according to the set ratio. The flow regulating valve 8 adjusts the flow rate through a PID controller 17.

[0021] As Figure 2 shown, it also includes a PLC controller. The PLC controller is connected to a touch screen. The weighing sensors in the flow meter 10 and the electronic belt scale 3 are connected to the input end of the PLC controller. The weighing sensors in the flow meter 10 and the electronic belt scale transmit the detected data to the PLC controller in real time. The drive motors in the first unloader 4, the second unloader 6, the flow regulating valve 8, and the electronic belt scale are connected to the output end of the PLC controller. The PLC controller controls the drive motors in the first unloader 4, the second unloader 6, the flow regulating valve 8, and the electronic belt scale 3.

[0022] The implementation process of the PLC controller is as follows: The addition amounts of phosphogypsum, organic fertilizer, nutrient soil, nutrient agent, and gelling agent are set through the touch screen. The first unloader 4, the second unloader 6, and the electronic belt scale convey the phosphogypsum, organic fertilizer, nutrient soil, and nutrient agent to the first conveyor 14 according to the set weight. The first conveyor 14 feeds the materials onto the second conveyor 7. The second conveyor 7 lifts and feeds the materials into the double-shaft stirring conveyor 13. The materials are mixed with water or gelling agent in the double-shaft stirring conveyor 13 and then enter the pellet forming machine 12 to be made into pellet finished products. Finally, the third conveyor 11 feeds the pellet finished products into the next unit.

[0023] The content described in the embodiments of this specification is only an enumeration of the implementation forms of the utility model concept. The protection scope of the present utility model should not be regarded as limited to the specific forms stated in the embodiments. The protection scope of the present utility model also extends to equivalent technical means that can be conceived by those skilled in the art based on the utility model concept.
