Technical Field
[0001] The present application relates to the field of sewage treatment, and in particular to a dissolution and stirring device for the production of industrial wastewater treatment agents. Background Art
[0002] Industrial wastewater refers to the wastewater generated during the industrial production process, which contains industrial production raw materials, intermediate products, by-products, and some pollutants, with complex compositions. If industrial wastewater is directly discharged into the river, it will cause serious pollution to the downstream water body. Therefore, it is necessary to carry out certain treatment on industrial wastewater before discharge.
[0003] Currently, the method of adding agents is usually adopted for industrial wastewater treatment. The agents react with the pollutants in the industrial wastewater to produce flocs, and the flocs are separated from the wastewater, thereby purifying the water quality.
[0004] In order to ensure the reaction efficiency between the agent and the industrial wastewater, the agent is generally put into the wastewater treatment device in small amounts and multiple times. However, if the flocs generated after adding the agent are not separated in time, it will affect the reaction efficiency between the agent and the wastewater during the subsequent stirring process.

Detailed Description of the Embodiment
[0031] The following is a further detailed description of the present application in conjunction with the attached Figures 1 - 3 drawings.
[0032] Referring to Figure 1 and Figure 2 , a dissolution and stirring device for the production of industrial wastewater treatment agents disclosed in an embodiment of the present application includes a tank body 1, a stirring assembly 2 and an opening and closing assembly 3. The cross-section of the tank body 1 in the horizontal direction is circular. A partition plate 11 is integrally formed in the tank body 1 in the horizontal direction. The partition plate 11 divides the interior of the tank body 1 into a treatment chamber 12 and a flocculation chamber 13. The treatment chamber 12 is located above the flocculation chamber 13. A water inlet valve 14 and a chemical addition valve 15 are fixedly installed at the top of the treatment chamber 12. Industrial wastewater is discharged into the treatment chamber 12 through the water inlet valve 14. The chemical addition valve 15 can quantitatively add chemicals into the treatment chamber 12. A drain valve 16 is fixedly installed on the lower side wall of the treatment chamber 12 for discharging the treated wastewater. The inner bottom wall of the flocculation chamber 13 is inclined downward from the direction away from the axis of the tank body 1 to the direction close to the axis of the tank body 1. A sludge discharge valve 17 is fixedly installed at the central position of the bottom of the flocculation chamber 13. The stirring assembly 2 is arranged on the tank body 1, and the opening and closing assembly 3 is arranged inside the tank body 1.
[0033] Referring to Figure 2, the stirring assembly 2 includes a motor 21, a rotating shaft 22 and stirring rods 23. The motor 21 is fixedly installed on the top of the tank body 1 by bolts. The output shaft of the motor 21 passes through the top wall of the tank body 1 and is fixedly connected to the rotating shaft 22. The rotating shaft 22 is rotatably connected in the treatment chamber 12 in the vertical direction. The stirring rods 23 are welded to the side wall of the rotating shaft 22 in the horizontal direction. Multiple stirring rods 23 can be provided. In this embodiment, three stirring rods 23 are provided.
[0034] After the dosing valve 15 adds the medicament into the treatment chamber 12, start the motor 21. The output shaft of the motor 21 drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the stirring rods 23 to rotate, disturbing the wastewater, making the wastewater fully contact with the medicament, and generating flocculants.
[0035] It should be noted that a controller 4 is fixedly installed on the outer wall of the tank body 1. After the stirring rods 23 stir the wastewater in the treatment chamber 12 for a certain time and generate some flocculants, the controller 4 controls the motor 21 to stop working, so that the flocculants can precipitate at the bottom of the treatment chamber 12. In addition, a scraper 5 is welded to the end of the stirring rod 23 far from the rotating shaft 22. The side wall of the scraper 5 is attached to the inner wall of the treatment chamber 12. The scraper 5 will rotate with the stirring rod 23, scraping off the flocculants adhered to the inner wall of the treatment chamber 12 and reducing the content of flocculants in the treatment chamber 12.
[0036] Refer to Figure 2 and Figure 3 , the opening and closing assembly 3 includes an electric telescopic rod 31, a connecting plate 32 and a blocking block 33. A through discharge hole 111 is vertically formed in the partition plate 11. The electric telescopic rod 31 is arranged in the vertical direction. The fixed end of the electric telescopic rod 31 is embedded in the bottom of the rotating shaft 22. The connecting plate 32 is a square plate, one end of which is welded to the movable end of the electric telescopic rod 31. The blocking block 33 is welded to the bottom of the connecting plate 32. The blocking block 33 passes through the discharge hole 111, and its side wall is attached to the inner wall of the discharge hole 111, capable of blocking the discharge hole 111. A square clamping block 311 is welded to the side of the movable end of the electric telescopic rod 31 close to the partition plate 11, and a corresponding connecting groove 221 is formed on the bottom wall of the rotating shaft 22. It should be noted that when the electric telescopic rod 31 contracts until the clamping block 311 is embedded in the connecting groove 221, the blocking block 33 is disengaged from the discharge hole 111. A touch switch 6 is fixedly installed on the inner bottom wall of the connecting groove 221. The touch switch 6 is electrically connected to the motor 21 through the controller 4.
[0037] After the flocs precipitate for a certain period of time, they accumulate at the bottom of the treatment chamber 12. The controller 4 controls the electric telescopic rod 31 to contract. When the clamping block 311 is inserted into the connection groove 221, the touch switch 6 is triggered. The controller 4 controls the motor 21 to start. At this time, the blocking block 33 disengages from the discharge hole 111, and the discharge hole 111 is opened. The electric telescopic rod 31 rotates along with the rotating shaft 22, and the blocking block 33 also rotates along with the electric telescopic rod 31, pushing the flocs at the bottom of the treatment chamber 12 to the discharge hole 111. After rotating one week, the controller 4 controls the motor 21 to stop rotating, and at the same time drives the electric telescopic rod 31 to extend. The blocking block 33 blocks the discharge hole 111. At this time, the chemical addition valve 15 can perform secondary chemical addition.
[0038] In addition, referring to Figure 2 , a sludge level gauge 7 is fixedly installed at the bottom of the partition plate 11. That is to say, the sludge level gauge 7 is located in the flocculation chamber 13. The sludge level gauge 7 can detect the accumulation height of the flocs in the flocculation chamber 13. The sludge level gauge 7 is electrically connected to the sludge discharge valve 17 through the controller 4. When the sludge level gauge 7 detects that the flocs in the flocculation chamber 13 have accumulated to a certain height, the controller 4 controls the sludge discharge valve 17 to open, so that the flocs can be discharged in time.
[0039] The implementation principle of a dissolution and stirring device for industrial wastewater treatment agent production in an embodiment of the present application is as follows: Industrial wastewater enters the treatment chamber 12 through the water inlet valve 14. The chemical addition valve 15 is opened to add the agent into the treatment chamber 12. The motor 21 is started. The output shaft of the motor 21 drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the stirring rod 23 to rotate, disturbing the wastewater and making the wastewater and the agent fully contact to generate flocs. After the motor 21 works for a certain period of time, the controller 4 controls the motor 21 to stop working. At this time, the flocs in the treatment chamber 12 precipitate to the bottom. After a certain period of time, the controller 4 controls the electric telescopic rod 31 to contract. When the clamping block 311 is inserted into the connection groove 221, the touch switch 6 is triggered. The controller 4 controls the motor 21 to start again. At this time, the blocking block 33 disengages from the discharge hole 111, and the discharge hole 111 is opened. The electric telescopic rod 31 rotates along with the rotating shaft 22, and the blocking block 33 also rotates along with the electric telescopic rod 31, pushing the flocs at the bottom of the treatment chamber 12 to the discharge hole 111. After rotating one week, the controller 4 controls the motor 21 to stop rotating, and at the same time drives the electric telescopic rod 31 to extend. The blocking block 33 blocks the discharge hole 111. At this time, the chemical addition valve 15 can perform secondary chemical addition to continue treating the wastewater in the treatment chamber 12. When the wastewater reaches the discharge standard, it can be discharged through the drain valve 16. When the sludge level gauge 7 detects that the flocs in the flocculation chamber 13 have accumulated to a certain height, the controller 4 controls the sludge discharge valve 17 to open, and the flocs are discharged through the sludge discharge valve 17. The present application can timely separate the flocs into the flocculation chamber 13 to ensure the reaction efficiency between the subsequent agent and the wastewater.
[0040] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
