Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment, and more specifically, to a quantitative acid-base dispensing device used in a hydrolysis acidification reaction process. Background Technology
[0002] Hydrolysis acidification is an anaerobic biological treatment process for organic wastewater. It transforms organic matter into smaller organic molecules through hydrolysis and acidification by microorganisms, thereby improving the biodegradability of the wastewater. In this process, microorganisms release extracellular free enzymes or fixed enzymes attached to their cell walls to complete the biocatalytic reaction. The acid and alkali powders used in the reaction are usually used to adjust the pH of the reaction system to ensure that hydrolytic acidifying bacteria and other microorganisms can carry out efficient biochemical reactions within a suitable pH range. However, existing wastewater treatment devices still have the following drawbacks:
[0003] Currently, pH adjustment is generally achieved by manually adding acid and alkali powders. However, excessive manual addition of acid and alkali powders can be toxic to microorganisms or inhibit their activity. Furthermore, acid and alkali powders often clump together during addition, affecting their dissolution rate and consequently impacting wastewater treatment efficiency. Therefore, a quantitative acid and alkali dosing device for the hydrolysis acidification reaction process is proposed. Utility Model Content

[0026] like Figure 1-6 As shown, this embodiment proposes an acid-base quantitative dosing device for use in a hydrolysis acidification reaction process, including a tank 1, a quantitative mechanism 2 at the bottom of the tank 1, and a collection component 3 on the outside of the tank 1.
[0027] like Figure 3 and Figure 5As shown, the metering mechanism 2 includes a feed pipe 201, a screen 202, a mounting plate 203, a vibrating motor 204, a discharge pipe 205, a cylinder 206, a servo motor 207, a round rod 208, a metering trough 209, a collection frame 210, and a discharge port 211. The feed pipe 201 is connected to the top of the tank 1, the screen 202 is fixedly connected to the inner wall of the tank 1, the mounting plate 203 is fixedly connected to the bottom of the screen 202, and the vibrating motor 204... A discharge pipe 205 is bolted to the bottom of the mounting plate 203 and connected to the bottom of the tank body 1. A cylinder 206 is connected to the bottom of the discharge pipe 205 and is arranged horizontally. A servo motor 207 is fixedly connected to the outer wall of the cylinder 206. A round rod 208 is coaxially arranged inside the cylinder 206 and rotatably connected to the cylinder 206. A metering groove 209 is formed on the outer wall of the round rod 208. A collection frame 210 is connected to the outer wall of the cylinder 206. The collection frame 210 is positioned opposite the discharge pipe 205, with the discharge port 211 located at the bottom of the collection frame 210. The screen 202 is tilted, and the feed pipe 201 is positioned above the higher end of the screen 202. The vibration motor 204 and the mounting plate 203 are located at the bottom of the higher end of the screen 202. The output end of the servo motor 207 is fixedly connected to the round rod 208 and can drive the round rod 208 to rotate. The metering tank 209 is normally facing the bottom of the discharge pipe 205. When in use, the vibration motor 204 and the servo motor 207 are started, and then the acid and alkali powder is poured into the feed pipe 201. The vibration motor 204 will cause the screen 202 to vibrate, causing the powder without lumps to fall into the discharge pipe 205 and the metering tank 209. Then, the servo motor 207 drives the round rod 208 to rotate 180 degrees, causing the acid and alkali powder in the metering tank 209 to fall into the collection frame 210 and then be discharged through the discharge port 211, thus completing the metering.
[0028] like Figure 3 As shown, the collection component 3 includes a connecting hole 301 and a collection chamber 302. The connecting hole 301 is opened on the outer wall of the tank 1, and the collection chamber 302 is bolted to the outer wall of the tank 1. The connecting hole 301 is located at the lower end of the screen 202, and the collection chamber 302 is located outside the connecting hole 301. When in use, the agglomerated acid and alkali powder will be guided into the collection chamber 302 by the inclined screen 202 for convenient subsequent unified processing.
[0029] like Figure 4 As shown, a flexible hose 4 is connected to the bottom of the discharge port 211. The flexible hose 4 is made of polytetrafluoroethylene (PTFE). When in use, the PTFE flexible hose 4 has excellent chemical stability and corrosion resistance. It can remain stable in various environments such as strong acids, strong alkalis, organic solvents, and oxidants. It can adjust the direction of discharge of acid and alkali powder and improve convenience.
[0030] like Figure 6As shown, a positioning frame 5 is fixedly connected to the side wall of the cylinder 206 away from the servo motor 207. A fixing ring 6 is fixedly connected to the end of the hose 4 away from the discharge port 211. An insertion rod 7 is fixedly connected to the outer wall of the fixing ring 6. The insertion rod 7 is inserted into the positioning frame 5. When the device is not in use, the insertion rod 7 is inserted into the interior of the positioning frame 5, so as to facilitate the storage of the hose 4.

The cross-sectional shape of the guide part 8 is a right triangle, and the upper surface of the guide part 8 is an inclined surface that slopes inward and downward. When in use, the guide part 8 can guide the acid and alkali powder and prevent some residual acid and alkali powder from remaining at the bottom corner of the tank 1.
[0032] like Figure 1 As shown, a support leg 9 is fixedly connected to the bottom of the tank body 1, and an installation ring 10 is fixedly connected to the bottom of the support leg 9. A threaded hole 11 is opened on the top of the installation ring 10. There are three support legs 9, which are distributed circumferentially along the central axis of the tank body 1. The installation ring 10 is annular in shape and coaxial with the tank body 1. There are several threaded holes 11, which are distributed circumferentially along the central axis of the tank body 1. When in use, external bolts are screwed into the threaded holes 11 to install and fix the device.
[0033] like Figure 1 As shown, an observation window 12 is provided on the side wall of the tank 1, which allows for convenient observation of the amount of remaining acid and alkali powder inside the tank 1 during use.
[0034] Specifically, the acid-base quantitative dosing device used in this hydrolysis acidification reaction process is operated as follows: External bolts are screwed into the threaded hole 11 to install and fix the device. Then, the servo motor 207 and vibration motor 204 are connected to an external power source. The vibration motor 204 and servo motor 207 are then started. Acid-base powder is poured into the feed pipe 201. The vibration motor 204 causes the screen 202 to vibrate, and the guide part 8 guides the acid-base powder, allowing un-clumped powder to fall into the discharge pipe 205 and the quantitative tank 209. Next, the servo motor 207 drives the round rod 208 to rotate 180 degrees, causing the acid-base powder in the quantitative tank 209 to fall into the collection frame 210 and then be discharged through the discharge port 211, thus completing the quantitative dosing. Clumped acid-base powder is then guided by the inclined screen 202 to the collection bin 302 for convenient subsequent unified processing.
[0035] All technical features in this embodiment can be freely combined according to actual needs.
[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
