Description

Technical Field

[0001] The utility model relates to the technical field of yellow phosphorus processing, in particular to a phosphate rock powder bin ash discharge valve. Background Art

[0002] Phosphate ore, the raw material for yellow phosphorus production, contains approximately 8% ash (which is somewhat sticky) upon entering the factory, and coke contains approximately 4% ash. Without drying and screening, this can lead to unstable production and low yields. After drying, the dust is removed using bags, and the dust is conveyed via an ash screw into three silos. Each silo is equipped with a 3kW ash screw discharge device at the bottom. These three devices consume approximately 50,000 yuan in electricity and labor costs for repair annually. Furthermore, the discharge process generates significant dust, increasing environmental risks and posing a risk to operators. Utility Model Content

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] Furthermore, a spiral structured discharge pipe is provided in the wall of the powder discharge pipe between the phosphate rock powder discharge valve and the annular water bin A.

[0007] Furthermore, the connection places of the annular water tank A, the annular water tank B and the annular water tank C with the water inlet valve are independently provided with flow valves A, flow valve B and flow valve C respectively.

[0008] Furthermore, the water supplied by the water supply pipe is recycled and treated water in the factory.

[0009] Furthermore, the angle of the atomizing nozzle is set to an inclined downward structure.

[0010] Furthermore, a powder discharge cover is provided at the bottom of the powder discharge pipe.

[0011] Compared with the prior art, the present invention can achieve one of the following beneficial effects:

[0012] 1. The bottom of the phosphate rock powder silo is connected to a powder discharge pipe; a phosphate rock powder discharge valve is installed at the connection between the powder discharge pipe and the phosphate rock powder silo; annular water silos A, B, and C are sequentially installed on the outer wall of the powder discharge pipe; annular water silos A, B, and C are respectively connected to water supply pipes; a water inlet valve is installed on the water supply pipe; annular water silo A is fixed to the outer wall of the powder discharge pipe via a connecting rod; an atomizing nozzle is embedded in the inner wall of the powder discharge pipe; the atomizing nozzle is annularly embedded in the inner wall of the powder discharge pipe; the atomizing nozzle is connected to annular water silo A via the nozzle water supply pipe; The annular water silo A is connected to the water supply pipe through a diversion pipe; the annular water silo A, annular water silo B and annular water silo C have the same structural settings, and can achieve the goal of humidifying the powder in the powder discharge pipe by spraying step by step by arranging multiple layers of annular water silos in the powder discharge pipe at the bottom of the phosphate rock powder silo, thereby reducing dust pollution during the discharge process; working principle: first open the process water main valve, and then open the ash powder silo gate valve. When the ash is in the process of descending, the water pressure is used to form three layers of spray, which fully and evenly moistens the descending ash and increases the moisture content of the ash, thereby achieving the purpose of controlling and reducing dust during the ash discharge process.

[0013] 2. A spiral structure discharge pipe is provided in the wall of the powder discharge pipe between the phosphate rock powder discharge valve and the annular water silo A. The spiral structure discharge pipe can realize uniform discharge and prevent the atomization effect from being affected by a sudden increase in the discharge amount directly discharged from the discharge pipe.

[0014] 3. The annular water sump A, annular water sump B and annular water sump C are independently provided with flow valves A, flow valve B and flow valve C at the connection with the water inlet valve, respectively. It is possible to adjust the atomizing water pressure of the atomizing nozzle in each annular water sump individually through the independently provided flow valves, thereby improving the atomization effect of the phosphate rock powder.

[0015] 4. The water supplied by the water supply pipe is recycled water from the factory. The recycled water from the factory can be used in the water supply pipe for humidification of phosphate rock powder through the arrangement, thereby saving water, achieving environmental protection, and reducing production costs.

[0016] 5. The angle of the atomizing nozzle is set to an inclined downward structure. By setting the angle of the atomizing nozzle slightly downward, the small resistance during the feeding process of the phosphate rock powder can be reduced, thereby improving the feeding efficiency.

[0017] 6. A powder discharge cover is provided at the bottom of the powder discharge pipe, which can reduce dust pollution at the discharge port during the discharge of phosphate rock powder. BRIEF DESCRIPTION OF THE DRAWINGS
