Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a combined treatment device for acidic and alkaline industrial wastewater. Background Technology

[0002] Wastewater refers to the total amount of water discharged during residential activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other non-water-using wastewater such as initial rainwater runoff into drainage pipes and ditches. Wastewater containing acidic or alkaline solutions is called acidic or alkaline wastewater. In order to better treat wastewater, it is necessary to treat acidic and alkaline industrial wastewater. The patent with authorization announcement number CN221254174U and title "An Acidic or Alkaline Wastewater Treatment Equipment" includes a box body. A motor is movably connected to the shaft at the top of the box body through a first bearing. A stirring rod is fixedly connected to the output end of the motor. A filter screen is sleeved on the top surface of the stirring rod. The filter screen is fixedly connected to the inner cavity of the box body. Stirring plates are fixedly connected to both sides of the stirring rod. An acid tank is set on the left side of the top of the box body, and an alkaline tank is set on the right side of the top of the box body. This acid and alkali wastewater treatment equipment, through the cooperation of a tank, motor, stirring rod, filter screen, stirring plate, acid tank, alkali tank, conduit, solenoid valve, scale plate, connecting pipe, threaded telescopic pipe, inlet pipe, movable plate, cylinder, detection pipe, and valves, can filter and remove impurities from wastewater, while controlling the amount of acid and alkali added to ensure complete neutralization of the wastewater, making it convenient for users. However, in actual use, the height of the stirring plate is fixed, and stirring can only occur on the horizontal plane where the stirring plate is located. Therefore, prolonged stirring is required to achieve uniform distribution of acid and alkali solutions in the wastewater, resulting in low efficiency. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a combined treatment device for acidic and alkaline industrial wastewater.

[0004] The technical solution adopted by this utility model to solve its technical problem is a combined treatment device for acidic and alkaline industrial wastewater, including a tank. A drain valve and multiple support legs are fixed at the bottom of the tank. A filter element is provided on one side of the tank, and a support is fixed on the other side of the tank. An acid tank, an alkali tank, and a water pump are fixed at the top of the support. Valves are fixed on both the acid tank and the alkali tank. A branch pipe is fixed on the inlet pipe of the water pump, and both valves are connected to the branch pipe. A connecting pipe is fixed on the drain pipe of the water pump. A tank cover is fixed at the top of the tank. A support is fixed at the top of the tank cover. A first hydraulic cylinder is fixed at the top of the support. A base is fixed at the bottom of the piston rod of the first hydraulic cylinder. A motor is fixed inside the base. The output shaft of the motor is connected to a vertical rod through a coupling. The vertical rod extends into the tank. Multiple stirring plates are fixed on the vertical rod. An annular spray pipe is fixed at the bottom of the tank cover. The spray pipe is connected to the end of the connecting pipe away from the water pump. Multiple nozzles are fixed at the bottom of the spray pipe.

[0005] By adopting the above technical solution, before the wastewater enters the tank, the filter can filter out impurities in the wastewater. Opening the valve on the acid or alkali tank allows the water pump to draw liquid from the acid or alkali tank. The acid or alkali is then sprayed into the tank through the nozzle, increasing the contact area between the acid or alkali and the wastewater. The piston rod of the first hydraulic cylinder drives the base to move vertically, which can adjust the height of the stirring plate. The output shaft of the motor drives the vertical rod to rotate, improving the mixing efficiency.

[0006] Specifically, the filter element includes a shell, a metal filter screen, and an activated carbon filter screen. The shell is connected to the tank body, and an end cap is provided at the end of the shell away from the tank body. A second hydraulic cylinder is provided above the shell body and is fixed to the tank body. A connecting block is fixed on the piston rod of the second hydraulic cylinder and is connected to the end cap. A telescopic tube is fixed on the end cap. A guide tube is fixed at the end of the shell away from the end cap and extends into the tank body. A metal filter screen and an activated carbon filter screen are provided inside the shell body. A pressure ring is provided on the side of the metal filter screen away from the activated carbon filter screen.

[0007] By adopting the above technical solution, the metal filter screen can filter impurities in wastewater, the activated carbon filter screen can adsorb odors, and the piston rod of the second hydraulic cylinder drives the connecting block to move away from the tank, which facilitates the opening of the end cover, and thus facilitates the removal, cleaning or replacement of the metal filter screen and the activated carbon filter screen.

[0008] Specifically, a sealing gasket is fixed inside the end cap.

[0009] By adopting the above technical solution, the sealing gasket can improve the sealing performance between the end cap and the outer shell.

[0010] Specifically, both the acid tank and the alkali tank are made of transparent material, and the outer walls of both the acid tank and the alkali tank are marked with graduations.

[0011] By adopting the above technical solution and setting the scale, it is convenient to determine the amount of acid or alkali solution to be added.

[0012] Specifically, both the acid tank and the alkali tank are equipped with protective covers on their tops.

[0013] By adopting the above technical solution, the protective cover can prevent debris from falling into the acid tank and alkali tank.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] In order to improve mixing efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3As shown, the present invention discloses a combined treatment device for acidic and alkaline industrial wastewater, comprising a tank 1. A drain valve 2 and multiple support legs are welded and fixed to the bottom of the tank 1. A filter element 4 is provided on one side of the tank 1, and a support 3 is welded and fixed to the other side of the tank 1. An acid tank 12, an alkali tank 14, and a water pump 22 are bolted to the top of the support 3. Valves 20 are welded and fixed to both the acid tank 12 and the alkali tank 14. A branch pipe 21 is welded and fixed to the inlet pipe of the water pump 22, and both valves 20 are welded and connected to the branch pipe 21. A connecting pipe 16 is welded and fixed to the drain pipe of the water pump 22. The tank 1... A tank cover 7 is bolted to the top, and a support 8 is welded to the top of the tank cover 7. A first hydraulic cylinder 11 is bolted to the top of the support 8. A base 9 is bolted to the bottom of the piston rod of the first hydraulic cylinder 11. A motor 10 is bolted to the base 9. The output shaft of the motor 10 is connected to a vertical rod 18 via a coupling. The vertical rod 18 extends into the tank body 1. Multiple stirring plates 19 are welded to the vertical rod 18. An annular spray pipe 15 is welded to the bottom of the tank cover 7. The spray pipe 15 is welded to the end of the connecting pipe 16 away from the water pump 22. Multiple nozzles 17 are welded to the bottom of the spray pipe 15.

[0025] During use, before the wastewater enters the tank 1, the filter element 4 filters out impurities in the wastewater. The filtered wastewater enters the tank 1, and the valve 20 on the acid tank 12 or alkali tank 14 is opened. The water pump 22 draws the liquid from the acid tank 12 or alkali tank 14. The acid or alkali is sprayed into the tank 1 through the nozzle 17, increasing the contact area between the acid or alkali and the wastewater. The output shaft of the motor 10 drives the vertical rod 18 to rotate, and the stirring plate 19 rotates accordingly. The piston rod of the first hydraulic cylinder 11 drives the base 9 to move vertically, which can adjust the height of the stirring plate 19 and improve the mixing efficiency.

[0026] To facilitate the removal of impurities, for example, such as Figure 1 , Figure 4 As shown, the filter element 4 includes a housing 40, a metal filter screen 43, and an activated carbon filter screen 44. The housing 40 is welded to the tank body 1. An end cap 42 is provided at the end of the housing 40 away from the tank body 1. A second hydraulic cylinder 6 is provided above the housing 40. The second hydraulic cylinder 6 is fixed to the tank body 1 by bolts. A connecting block 5 is fixed to the piston rod of the second hydraulic cylinder 6 by bolts. The connecting block 5 is welded to the end cap 42. A telescopic tube 45 is welded to the end cap 42. A conduit 41 is welded to the end of the housing 40 away from the end cap 42. The conduit 41 extends into the tank body 1. The housing 40 contains a metal filter screen 43 and an activated carbon filter screen 44. A pressure ring 47 is provided on the side of the metal filter screen 43 away from the activated carbon filter screen 44.

[0027] When in use, the metal filter screen 43 can filter impurities in the wastewater, and the activated carbon filter screen 44 can adsorb odors. The piston rod of the second hydraulic cylinder 6 drives the connecting block 5 to move away from the tank body 1, which facilitates the opening of the end cover 42, and thus facilitates the removal, cleaning or replacement of the metal filter screen 43 and the activated carbon filter screen 44.

[0028] To improve sealing, for example, such as Figure 4 As shown, a sealing gasket 46 is fixed inside the end cap 42 by adhesive.

[0029] To facilitate determining the amount of acid and alkali to be added, for example, such as Figure 1 As shown, both the acid tank 12 and the alkali tank 14 are made of transparent material, and the outer walls of both the acid tank 12 and the alkali tank 14 are marked with graduations.

[0030] To prevent debris from falling into acid tank 12 and alkali tank 14, for example, such as Figure 1 As shown, both the acid tank 12 and the alkali tank 14 are equipped with protective covers 13 at their top.

[0031] In use, wastewater is introduced into tank 1 through telescopic pipe 45. Before the wastewater enters tank 1, metal filter screen 43 can filter impurities in the wastewater, and activated carbon filter screen 44 can adsorb odors. The filtered wastewater enters tank 1.

[0032] Open the valve 20 on the acid tank 12 or the alkali tank 14, and the water pump 22 draws the liquid from the acid tank 12 or the alkali tank 14. The acid or alkali is sprayed into the tank 1 through the nozzle 17, which increases the contact area between the acid or alkali and the wastewater. The output shaft of the motor 10 drives the vertical rod 18 to rotate, and the stirring plate 19 rotates accordingly. The piston rod of the first hydraulic cylinder 11 drives the base 9 to move vertically, which can adjust the height of the stirring plate 19 and improve the mixing efficiency.

[0033] The piston rod of the second hydraulic cylinder 6 drives the connecting block 5 to move away from the tank body 1, which facilitates the opening of the end cover 42, and thus facilitates the removal, cleaning or replacement of the metal filter screen 43 and the activated carbon filter screen 44.
