Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a deep purification treatment device for water used in meat washing. Background Technology

[0002] Slaughter and meat processing wastewater is wastewater generated during slaughter or meat processing. It mainly contains blood, grease, meat scraps, animal hair, undigested food, feces, and urine. Its characteristics include large volume, uneven drainage, high concentration, many impurities and suspended solids, and good biodegradability. At the same time, its biggest difference from other high-concentration organic wastewater is its higher ammonia nitrogen concentration.

[0003] While current wastewater treatment methods employing a physicochemical + two-stage AO process can effectively treat most pollutants in wastewater, their effect on total nitrogen removal is limited, reaching a maximum of only 10-15 mg / L. For enterprises with emission requirements below 10 mg / L, this process is clearly insufficient and cannot achieve further deep nitrogen removal. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 As shown, a deep purification treatment device for meat washing water includes a treatment tank body 1. An inlet pipe 2 is connected to the left side of the treatment tank body 1. A nitrate nitrogen online detector 3 is installed on the rear side of the treatment tank body 1, and the monitoring head of the nitrate nitrogen online detector 3 extends into the interior of the treatment tank body 1. A support frame 4 is bolted to the right side of the top of the treatment tank body 1, and a storage tank 5 is fixed to the surface of the support frame 4. The storage tank 5 is filled with nitrate nitrogen removal agent, and a solenoid valve 6 is connected to the bottom of the storage tank 5. The treatment tank body 1 is connected to a discharge pipe 7. A support plate 8 is bolted to the right side of the top of the treatment tank body 1. A weighing sensor 9 is fixed to the left side of the top of the support plate 8. A receiving box 10 is fixed to the top of the sensing plate of the weighing sensor 9. Mounting shells 11 are fixed to the front and rear sides of the top of the treatment tank body 1. A moving structure 12 is provided inside the mounting shell 11. A moving plate 13 is provided above the treatment tank body 1. A vibration structure 14 is fixed to the front and rear sides of the surface of the moving plate 13. A discharge trough 15 is opened on the top surface of the moving plate 13.

[0024] A support platform 16 is fixed to the front and rear sides of the right side of the receiving box 10. A cylinder 17 is fixed to the top of the support platform 16. A pusher plate 18 is slidably connected to the right side of the inner wall of the receiving box 10. The output shaft of the cylinder 17 is fixedly connected to the right side of the pusher plate 18. When the nitrate removal agent falls into the receiving box 10, the weighing sensor 9 below weighs the nitrate removal agent in the receiving box 10. When the weight of the nitrate removal agent reaches the treatment requirement of the treatment tank body 1, the cylinder 17 on the right side will open. The output shaft of the cylinder 17 pushes the pusher plate 18 to the left. The pusher plate 18 can push the nitrate removal agent in the receiving box 10 down to denitrify the wastewater.

[0025] The movable structure 12 includes a first motor 121, a lead screw 122, and a movable platform 123. The first motor 121 is fixed on the left side of the mounting shell 11. The lead screw 122 is rotatably connected to the inside of the mounting shell 11. The movable platform 123 is slidably connected to the right side of the inner wall of the mounting shell 11, and the lead screw 122 passes through the movable platform 123 and is threadedly connected to the movable platform 123. Guide rails 19 are fixed on both the front and rear sides of the inner wall of the mounting shell 11, and the movable platform 123 is slidably connected to the guide rails 19. When the first motor 121 is turned on, the output shaft of the first motor 121 will drive the lead screw 122 to rotate, thereby causing the movable platform 123 to move the movable plate 13 above it. The movable platform 123 is guided by the guide rails 19 so that the nitrate removal agent can be evenly sprayed inside the treatment tank body 1.

[0026] The vibration structure 14 includes a fixed plate 141, a spring 142, and a vibration motor 143. The fixed plate 141 is fixed to the top of the movable platform 123. The spring 142 is fixed to the left and right sides of the top of the fixed plate 141, and the top of the spring 142 is fixedly connected to the bottom of the movable plate 13. The vibration motor 143 is fixed to the front and rear sides of the top of the movable plate 13. When the movable plate 13 moves left and right, the operator can open the vibration motor 143, thereby causing the movable plate 13 to vibrate, so as to shake out the nitrate nitrogen removal agent inside the discharge trough 15, so that the nitrate nitrogen removal agent falls into the wastewater below.

[0027] The movable plate 13 is located below the receiving box 10, and the left and right sides of the inner wall of the discharge trough 15 are inclined. After the nitrate nitrogen removal agent in the receiving box 10 falls, the nitrate nitrogen removal agent will enter the interior of the discharge trough 15. Through the setting of the inner wall of the discharge trough 15, the nitrate nitrogen removal agent can fall slowly. With the left and right back and forth movement of the movable plate 13, the nitrate nitrogen removal agent is evenly sprinkled inside the treatment tank body 1, thereby improving the denitrification effect.

[0028] Working principle: When wastewater generated during slaughtering or meat processing enters the treatment tank body 1 through the inlet pipe 2, the online nitrate nitrogen detector 3 detects the nitrate nitrogen content in the wastewater. After detection, the solenoid valve 6 below the storage tank 5 opens, pouring the nitrate nitrogen removal agent from the storage tank 5 into the receiving box 10 below. The weighing sensor 9 on the top of the support plate 8 weighs the nitrate nitrogen removal agent in the receiving box 10, discharging the corresponding weight of nitrate nitrogen removal agent according to the nitrate nitrogen content. When the weight of the nitrate nitrogen removal agent in the receiving box 10 reaches the required level, the solenoid valve 6 closes, and the cylinder on the right side... 17 is opened, allowing the pusher plate 18 to push the nitrate removal agent inside the receiving box 10 into the discharge trough 15 below. Then, the operator turns on the first motor 121 and the vibration motor 143 on both sides, causing the moving plate 13 to move to the left and vibrate as a whole. The nitrate removal agent inside the discharge trough 15 slowly falls into the treatment tank body 1 below and comes into contact with the wastewater. The operator controls the rotation direction of the output shaft of the first motor 121, causing the moving plate 13 to move back and forth, evenly spreading the nitrate removal agent on the wastewater, thus completing the denitrification and dosing treatment of the wastewater inside the treatment tank body 1.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
