Description

[0003] Under the existing technology, if there are problems such as flow rate fluctuations and uneven pressure in the feed pump, it will cause the flow rate of the ammonia-containing solution entering the stripping tower to be unstable, resulting in uneven feeding. Some old feed pumps may not be able to provide a constant output pressure due to wear, poor sealing, etc., making the feeding volume of the solution vary at different times, and the uneven concentration of the ammonia-containing solution itself may also lead to uneven feeding. If the solution is not fully mixed or stratified during preparation or storage, the ammonia content in the solution entering the stripping tower will be inconsistent, thus affecting the stripping effect and the uniformity of feeding. For this reason, we propose a feeding device for an ammonia stripping tower to solve the above problems. Summary of the Utility Model

[0023] Embodiment: As Figures 1-5 shown, the present utility model provides a feeding device for an ammonia stripper, including a storage tank 1. A feed pipe 101 is fixedly connected to the top of the storage tank 1. One end of the feed pipe 101 close to the storage tank 1 passes through the tank body and extends to the bottom of the storage tank 1. One end of the feed pipe 101 at the bottom of the storage tank 1 is fixedly connected to a feed tray 103. One end of the feed pipe 101 far from the storage tank 1 is fixedly connected to an assembly pipe 102. A control component 2 is arranged inside the assembly pipe 102. A discharge pipe 104 is fixedly connected to the bottom of the assembly pipe 102. A one-way air valve for cooperating with the control component 2 is installed on the top of the storage tank 1. The one-way air valve ensures the air pressure balance inside and outside the storage tank 1 during the subsequent operation of the control component 2, and ensures the normal operation of the feeding device.
[0024] Furthermore, a tapered ring 201 is provided in the control component 2. The tapered ring 201 is arranged at the connection of the feed pipe 101 and the assembly pipe 102. The tapered ring 201 is fixedly connected to the assembly pipe 102. A plug ball 202 is arranged on the side of the tapered ring 201 away from the feed pipe 101. The plug ball 202 completely closes the inner ring of the tapered ring 201. A fixing groove 203 is formed on the side of the plug ball 202 away from the tapered ring 201. A return spring 204 is arranged in the fixing groove 203. One end of the return spring 204 is fixedly connected to the bottom of the inner cavity of the fixing groove 203. A connecting cylinder 205 is sleeved on the other end of the return spring 204. One end of the connecting cylinder 205 away from the return spring 204 is fixedly connected to a fixing plate 206. A plurality of connecting plates 207 are fixedly connected around the fixing plate 206. The plurality of connecting plates 207 are evenly distributed around the axis of the fixing plate 206. The end of the connecting plate 207 away from the fixing plate 206 is fixedly connected to the inner wall of the assembly pipe. An even plate 208 is fixedly connected to the inner wall of the assembly pipe. The even plate 208 is arranged on the side of the discharge pipe 104 close to the sieve ball. A plurality of fine holes 209 penetrating through itself are formed on the surface of the even plate 208. The plurality of fine holes 209 are evenly distributed on the surface of the even plate 208. A moving seat 210 is arranged at the end of the inner cavity of the assembly pipe 102 away from the feed pipe 101. The moving seat 210 is slidably connected to the inner wall of the assembly pipe 102. A fixing ring groove 211 is formed around the moving seat 210. A sealing ring 212 is sleeved in the fixing ring groove 211. The outer ring wall of the sealing ring 212 contacts and is slidably connected to the inner wall of the assembly pipe 102. A telescopic cylinder 213 is installed on the side of the moving seat 210 away from the feed pipe 101. The output end of the telescopic cylinder 213 is fixedly connected to the moving seat 210. The tail of the telescopic cylinder 213 is fixedly connected to the side of the inner cavity of the assembly pipe 102 away from the feed pipe 101. In the initial state, the telescopic cylinder 213 is in the initial position, on the side of the moving seat 210 close to the feed pipe 101. At this time, the plug ball 202 completely closes the inner ring of the tapered ring 201 under the action of the return spring 204. When the telescopic cylinder 213 is started, the output end of the telescopic cylinder 213 extends, driving the moving seat 210 away from the feed pipe 101. At this time, a negative pressure is formed in the assembly pipe 102, and the plug ball 202 is attracted by the negative pressure and moves away from the tapered ring 201. The ammonia-containing solution enters from the feed pipe 101 and passes through the tapered ring 201. Since the plug ball 202 is pulled open, the solution passes through smoothly. After the solution enters the assembly pipe 102, it passes through the even plate 208, and the plurality of fine holes 209 on the surface of the even plate 208 make the solution fully mixed. The telescopic cylinder 213 contracts, driving the moving seat 210 close to the feed pipe 101. At this time, the moving seat 210 squeezes the solution in the assembly pipe 102, so that the plug ball 202 is squeezed to completely close the tapered ring 201, and the ammonia-containing solution can only be discharged from the discharge pipe 104.
[0025] Working principle: When using this device, in the initial state, the telescopic cylinder 213 is in the initial position, and the moving seat 210 is close to the feeding pipe 101. At this time, the plug ball 202 completely closes the inner ring of the conical ring 201 under the action of the return spring 204. Start the telescopic cylinder 213, and the output end of the telescopic cylinder 213 extends, driving the moving seat 210 away from the feeding pipe 101. At this time, a negative pressure is formed in the assembly pipe 102, and the plug ball 202 is attracted by the negative pressure and moves away from the conical ring 201. The ammonia-containing solution enters from the feeding pipe 101, passes through the conical ring 201. Since the plug ball 202 is pulled open, the solution passes through smoothly. After the solution enters the assembly pipe 102, it passes through the uniform disk 208, and the multiple fine holes 209 on the surface of the uniform disk 208 make the solution fully mixed.
[0026] The telescopic cylinder 213 contracts, driving the moving seat 210 close to the feeding pipe 101. At this time, the moving seat 210 squeezes the solution in the assembly pipe 102, so that the plug ball 202 is squeezed to completely close the conical ring 201, and the ammonia-containing solution can only be discharged from the discharge pipe 104. During the whole process, the one-way air valve at the top of the storage tank 1 ensures the air pressure balance inside and outside the storage tank 1, ensuring the normal operation of the feeding device.
[0027] By controlling the movement of the moving seat 210 through the telescopic cylinder 213, the opening and closing control of the plug ball 202 can be realized, and the feeding amount and feeding time of the ammonia-containing solution can be accurately controlled. The setting of the uniform disk 208 enables the ammonia-containing solution to be fully mixed after entering the assembly pipe 102, improving the uniformity of the solution, which is beneficial to the subsequent ammonia vapor extraction process. The setting of the one-way air valve ensures the air pressure balance inside and outside the storage tank 1, avoiding equipment damage or safety accidents caused by air pressure changes.
[0028] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these changes and modifications.
