Description
Technical Field
[0001] The utility model relates to the technical field of chemical production, in particular to an adding device for desulfurization and denitrification in phosphate and calcium production. Background Art
[0002] At present, manufacturers need to add urea when producing phosphate fertilizers. The main purpose is to use the ammonia in urea to treat the waste gas generated in the production process of phosphate fertilizers. The nitrogen and sulfide in these waste gases will react with urea under certain circumstances, and finally achieve the desulfurization and denitrification of the waste gas. At present, the urea required to be added in the production process of phosphate fertilizers is often divided into liquid urea and granular urea. Since the water in liquid urea easily reacts with the substances in the phosphate fertilizer during the reaction, urea granules are generally used to react with the waste gas at high temperature in the actual production process. The current equipment for adding urea is relatively complex and difficult to control.
[0003] In view of such a situation, the patent with publication number CN106714955B discloses a device and method for converting a liquid, preferably a urea melt, into granular form. In this patent, the structure is relatively complex. The pulser is located in the feeder. The feeder is a liquid feeding method, and the feed is fed from the back of the pulser. Since urea is in a granular state, the feeding pipe is easily blocked during the feeding process, and it is not easy to check and repair. Utility Model Content

DETAILED DESCRIPTION
[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0027] Reference Figures 1 to 5The shown addition device for desulfurization and denitrification in phosphate calcium production includes a frame 10, a hopper 20, a support ring frame 30, a pneumatic conveying mechanism 40, a turntable 50 and a driving mechanism 60, wherein the hopper 20 is mounted on the frame 10; the support ring frame 30 is mounted on the frame 10 and is sleeved outside the discharge end of the hopper 20; a discharge port 31 is provided on one side of the support ring frame 30; the pneumatic conveying mechanism 40 is mounted on the frame 10, and the pneumatic conveying mechanism 40 can receive the material discharged from the discharge port 31; the turntable 50 can be rotatably mounted in the support ring frame 30 and is sealed on the discharge end of the hopper 20; the driving mechanism 60 is mounted on the frame 10, and the driving mechanism 60 is used to drive the turntable 50 to rotate to drive the material in the hopper 20 to be discharged from the discharge port 31.
[0028] The turntable 50 is sealed on the discharge end of the hopper 20. In order to ensure the discharge, a plurality of receiving grooves can be arranged on the turntable 50 along the center to radiate outward, so that the granular material in the hopper 20 can be discharged outward through the receiving grooves. Of course, in some embodiments, the turntable 50 is not completely sealed on the discharge end of the hopper 20, and there is a certain gap between the two, so that the granular material in the hopper 20 can be discharged outward with the rotation of the turntable 50. The driving mechanism 60 is a servo motor in this application, which is convenient for controlling the rotation.
[0029] In addition, the support ring 30 is actually a limiting structure for limiting the particles on the rotating disk 50.
[0030] while the support ring frame 30 can also play the role of stacking the scattered granular material on the turntable 50, so that the stacked granular material can be used to increase the stacking pressure, to prevent the material particles in the hopper 20 from flowing out through the gap between its outlet end and the turntable 50 due to their own weight.
[0031] The addition device for desulfurization and denitrification of phosphate and calcium production uses a hopper 20 to hold granular urea, and uses a turntable 50 to discharge granular urea in cooperation with the hopper 20. Such a discharge speed is controllable. At the same time, the characteristics of the turntable 50 ensure that the particles are not discharged in a specific direction after being discharged from the hopper 20, so that the particles are not easily blocked. The support ring frame 30 is mounted on the outer edge of the discharge end of the hopper 20, which can effectively block and collect urea particles diffused toward the periphery of the turntable 50, which is conducive to the urea particles falling from the discharge port 31 into the pneumatic conveying mechanism 40. In this way, the entire feeding process is an open design, which is not easy to be blocked, reduces the difficulty of maintenance, and improves the convenience of use.
[0032] See also Figures 1 to 3In order to better install the support ring frame 30, in one embodiment of the present application, the support ring frame 30 includes a plurality of mounting legs 32 and an open hoop 33. All the mounting legs 32 are mounted on the frame 10. A position-adjustable connecting rod 34 is provided on the inner side of all the mounting legs 32. The inner ends of all the connecting rods 34 are connected to the outer wall of the open hoop 33. The lower end of the open hoop 33 abuts against the upper surface of the turntable 50. The opening of the open hoop 33 cooperates with the upper surface of the turntable 50 to form the discharge port 31. The mounting legs 32 are arranged around the outer periphery of the discharge end of the hopper 20. The main purpose of designing the connecting rod 34 is to facilitate the staff to adjust the coaxiality of the entire open hoop 33 and the turntable 50, which is conducive to ensuring that the open hoop 33 can effectively limit the granular materials scattered from the turntable 50.
[0033] In some embodiments, the open hoop 33 may also be a spiral structure, so that the granular material in the middle of the rotating disk 50 can be gradually discharged outwards.
[0034] In order to better adjust the position of the connecting rod 34 and thus the position of the open hoop 33, in an improved solution of the above-mentioned embodiment, all the mounting legs 32 are provided with mounting long waist holes 35, and the outward end of the connecting rod 34 is slidably mounted in the mounting long waist hole 35, and the outward end of the connecting rod 34 is located on both sides of the mounting legs 32 and is locked and fixed by locking nuts 36. Through such a setting, the staff can adjust the installation position of each connecting rod 34 according to the actual installation requirements, and then adjust the installation position of the open hoop 33 to adapt to the turntable 50.
[0035] Furthermore, in some embodiments, in order to better allow the materials scattered from the discharge port 31 to fall into the pneumatic conveying mechanism 40, the open hoop 33 is provided with a baffle 37 on one side of the opening thereof, and the baffle 37 is provided on one side of the rotation direction of the turntable 50. The baffle 37 is a hinged structure, which is mounted on one end of the opening of the open hoop 33 by bolts.
[0036] In order to prevent the granular materials accumulated in the rotating disk 50 from overflowing the open ring hoop 33, in an improved embodiment of the present application, a detachable guard plate 38 is provided on the upper edge of the open ring hoop 33, and the guard plate 38 abuts against the outer wall of the hopper 20. The guard plate 38 is made of a soft material, such as rubber or plastic, so that it is easy to fit the installation position of the hopper 20 and the open ring hoop 33, thereby improving the adaptability of the installation.
[0037] Furthermore, in order to make the open hoop 33 and the turntable 50 fit more closely, in one embodiment, a boss 51 is provided on the upper surface of the turntable 50, and the open hoop 33 surrounds the outer side of the boss 51. This design allows the granular material to be discharged from the discharge port 31 and can be discharged along the turntable 50.
[0038] See also Figure 4 and Figure 5 In the present application, the pneumatic conveying mechanism 40 can be a conventional pulse gas conveying mechanism or a pneumatic push conveying mechanism, which is selected according to the actual use requirements. In addition, in one embodiment of the present application, the pneumatic conveying mechanism 40 includes a collecting hopper 41, a feeding pipe 42 and an air intake pipe 43. The collecting hopper 41 is installed on the frame 10 and is located directly below the discharge port 31. One end of the feeding pipe 42 is connected to the bottom of the collecting hopper 41, and the end of the feeding pipe 42 connected to the collecting hopper 41 is connected to one end of the air intake pipe 43, and the other end of the air intake pipe 43 is used to connect to the air intake device. Among them, the air intake device can be a pulse gas generator or a conventional air compressor; and because the amount of particulate material dropped after coming out of the turntable 50 is relatively small, the size of the collecting hopper 41 is relatively small. It should be noted that, in order to prevent the pressurized gas blown into the air intake pipe 43 from rushing out of the collecting hopper 41, the outlet end of the air intake pipe 43 in the present application is closer to the outlet end of the feed pipe 42 than the connection between the feed pipe 42 and the collecting hopper 41. In addition, the diameter of the air intake pipe 43 is smaller than the diameter of the feed pipe 42.
[0039] It should be noted that in the above embodiment, a three-way joint is provided on the feed pipe 42, and the bottom of the collecting hopper 41 is mounted on the three-way joint, and the two are connected by bolts. The three-way joint is a Y-shaped joint, and the air intake pipe 43 and the collecting hopper 41 are respectively mounted on the two ends of the Y-shaped joint that are close to each other, so that the gas blown out of the air intake pipe 43 can be prevented from being ejected from the collecting hopper 41 and affecting the feed.
[0040] See also Figure 4 and Figure 5 In some embodiments, in order to facilitate the subsequent dredging and maintenance of the feed pipe 42, an air intake cover 44 is provided at one end of the feed pipe 42 that is connected to the collecting hopper 41, and a cover plate 45 is sealed on the opening of the air intake cover 44. One end of the air intake pipe 43 is mounted on the cover plate 45 and connected to the air intake cover 44. In fact, the outlet end of the air intake pipe 43 needs to be inserted into the feed pipe 42 until the outlet end is closer to the outlet end of the feed pipe 42 than the connection between the feed pipe 42 and the collecting hopper 41.
[0041] See also Figure 5In some embodiments, in order to facilitate the adjustment of the flow capacity between the collecting bucket 41 and the feeding pipe 42, the feeding pipe 42 is provided with an adjustment hole 46 below the connection with the collecting bucket 41, and an adjusting bolt 47 is screwed into the adjusting hole 46. The adjusting bolt 47 can be inserted into the outlet of the collecting bucket 41. In fact, the diameter of the adjusting bolt 47 is smaller than the outlet diameter of the collecting bucket 41, so that the flow capacity between the collecting bucket 41 and the feeding pipe 42 can be adjusted according to the insertion depth.
[0042] See also Figure 5 In some improved embodiments, in order to facilitate the connection of the air intake pipe 43 , an access pipe 48 is provided on the cover plate 45 , one end of the air intake pipe 43 is connected to the access pipe 48 , and the access pipe 48 is coaxially arranged with the feed pipe 42 .
[0043] The above-mentioned implementation is only a preferred implementation of the present utility model, and cannot be used to limit the scope of protection of the present utility model. Any non-substantial changes and replacements made by technicians in this field on the basis of the present utility model fall within the scope of protection required by the present utility model.
