Description

Technical Field

[0001] This utility model relates to the field of fertilizer production, and in particular to a decolorizing agent addition device for the production of monoammonium phosphate. Background Technology

[0002] Monoammonium phosphate (MAP) is a widely used nitrogen-phosphorus binary compound fertilizer containing both nitrogen and phosphorus, essential nutrients for crop growth. It is suitable for various soils and crops, effectively promoting root growth, improving stress resistance, and increasing yield. MAP production typically involves a neutralization reaction between dilute phosphoric acid and gaseous ammonia. Dilute phosphoric acid is often obtained from phosphate rock via a wet process. To achieve the desired color, the dilute phosphoric acid obtained through the wet process is often pretreated by adding a bleaching agent. Currently, the bleaching agent is added manually by pouring it into the dilute phosphoric acid mixture, resulting in low production efficiency, wasting the bleaching agent, and negatively impacting the bleaching effect.

The storage tank 2 is used to store and supply the bleaching agent. A transmission assembly 3 is welded to the top of the pretreatment tank 1. A spraying assembly 8 and a stirring component 18 are welded to the outer wall of the transmission assembly 3. The spraying assembly 8 includes a first spraying component 801 and a second spraying component 802. An input pipe 4 and an output pipe 5 are respectively provided on the outer wall of the pretreatment tank 1. A first valve 6 is welded to the end of the input pipe 4 away from the pretreatment tank 1, and a second valve 7 is welded to the end of the output pipe 5 away from the pretreatment tank 1. The first valve 6 is used to control the inflow of material, and the second valve 7 is used to control the discharge of the processed finished material. The transmission assembly 3 includes a support plate 301, which serves as the base support 311 of the entire transmission assembly 3 and is welded to the top of the pretreatment tank 1. The bottom of the support plate 301 is welded with a first slide groove 302 and a second slide groove 303. Slider 1 304 and slider 2 305 are respectively installed in slide groove 1 302 and slide groove 2 303. Slide groove 1 302 and slide groove 2 303 provide defined tracks for slider 1 304 and slider 2 305, ensuring smooth sliding along a straight line. The top of slider 1 304 is welded with... Connecting block 306 is attached to the top of slider 305, connecting block 307 is welded to the top of slider 305, slider 304 is welded to the bottom of spray component 801, slider 305 is welded to the bottom of spray component 802, conveying pipe 9 is welded to the outer wall of slider 304, one end of conveying pipe 9 extends into the slider and is welded to spray component 801, and conveying pipe 10 is welded to the outer wall of slider 305, one end of conveying pipe 10 extends into the slider and is welded to spray component 802. Conveying pipe 9 and conveying pipe 10... 10 is a rigid conduit with a connecting function, responsible for conveying the fading agent to sprayer 801 and sprayer 802 respectively. Fixing base 308 and fixing base 309 are welded to the top of the support plate 301 respectively. A reciprocating screw 310 is rotatably connected to the outer wall of fixing base 308. The end of the reciprocating screw 310 away from fixing base 308 is rotatably connected to fixing base 309. Fixing base 308 and fixing base 309 are used to install and support both ends of the reciprocating screw 310, ensuring its stable rotation. Connecting block 1 306 and connecting block 2 307 are threaded to the outer wall of the reciprocating screw 310. Connecting block 1 306 and connecting block 2 307 connect slider 1 304 to the reciprocating screw 310 and slider 2 305 to the reciprocating screw 310, respectively, converting the rotational motion of the screw into its own linear reciprocating motion. A bracket 311 is welded to the top of the support plate 301. The bracket 311 is used to fix and support the motor 312. The output end of the motor 312 extends to the fixed seat 2 309 and is welded to the reciprocating screw 310. The outer wall of chute 1 302 is provided with sliding groove 1, and the outer wall of chute 2 303 is provided with sliding groove 2.

The top of the connecting plate 315 is rotatably connected to bevel gear 2 314. Bevel gear 1 313 and bevel gear 2 314 mesh. Bevel gear 1 313 and bevel gear 2 314 form a reversing gear pair, which converts the horizontal rotational power of the reciprocating screw 310 into vertical rotational power to drive the stirring component 18. The lower end face of bevel gear 2 314 is welded with a rotating roller 31. 6. The rotating roller 316 passes through the connecting plate 315. The outer wall of the rotating roller 316 is welded to the stirring component 18. After the stirring component 18 rotates, it mechanically stirs the material and bleaching agent in the pretreatment tank 1, making the two more uniformly mixed, accelerating the reaction, and improving production efficiency. The top of the pretreatment tank 1 is provided with a slide rail 11. Sliding block 12 and sliding block 2 13 are respectively provided on the slide rail 11. The end of the conveying pipe 19 away from the slider 1 304 passes through the sliding block 12, and the end of the conveying pipe 2 10 away from the slider 2 305 passes through the sliding block 2 13.

A water pump 14 is welded to the outer wall of the storage tank 2. A two-way valve 15 is welded to the output end of the water pump 14. A hose 16 is threaded to one end of the conveying pipe 19 that passes through the sliding block 12. A hose 17 is threaded to one end of the conveying pipe 20 that passes through the sliding block 23. Hose 16 and hose 27 are threaded to the two-way valve 15 respectively. Hose 16 and hose 27 are flexible pipes that serve as connections and conveyors, and are used to compensate for the displacement difference generated when the transmission component 3 moves. The working principle of this utility model is as follows: When pre-treating the material to be processed, first open valve 6 to allow it to enter the pre-treatment tank 1 through input pipe 4. Then close valve 6 and turn on motor 312, causing reciprocating screw 310 to rotate. Connecting block 306 and connecting block 307 reciprocate accordingly, driving slider 304 to slide in slide groove 302 and slider 305 to slide in slide groove 303. The two sliders slide in the same direction. The conveying pipe 9 and spraying component 801, which are respectively welded to the outer wall of slider 304, also move accordingly. Correspondingly, the conveying pipe 10 and spraying component 802, which are respectively welded to the outer wall of slider 305, move in the same direction. At the same time, bevel gear 313, which is welded to the outer wall of reciprocating screw 310, also starts to rotate, driving bevel gear 314, which meshes with bevel gear 313. 14 also rotates, causing the rotating roller 316 welded to the lower end face of bevel gear 2 314 to start rotating, eventually causing the stirring component 18 to start working normally. At this time, the water pump 14 is turned on, and the water pump 14 pumps out the bleaching agent in the storage tank 2 and delivers it to the conveying pipe 1 9 and the conveying pipe 2 10 through the hose 1 16 and the hose 2 17 respectively. Then, it is delivered to the spraying component 1 801 and the spraying component 2 802 through the conveying pipe 1 9 and the conveying pipe 2 10. Through repeated spraying, not only can the bleaching agent be fully mixed with the material, but the production efficiency is also improved. After the predetermined amount of spraying is reached, the water pump 14 is turned off first, and after waiting for a while, the motor 312 is turned off, so that the bleaching agent remaining in the conveying pipe continues to be sprayed evenly with the movement, and the mixture is stirred by the stirring component 18 to improve the production rate. After the pretreatment of the material is completed, the valve 2 7 is opened to output the processed material from the output pipe 5.

[0016] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
