Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary treatment devices for industrial wastewater, specifically a calcium oxide suspension addition device. Background Technology

[0002] Industrial wastewater refers to wastewater and waste liquid generated during industrial production. Because industrial wastewater often contains a variety of toxic substances and is acidic, indiscriminate discharge can cause great harm to the environment and human health. Therefore, it is necessary to develop comprehensive utilization, turn harm into benefit, and take corresponding purification measures according to the composition and concentration of pollutants in the wastewater before it can be discharged.

[0003] In the process of industrial wastewater treatment, calcium oxide suspension dosing devices are generally used. Because calcium oxide suspension is alkaline, the dosing device can add it to acidic wastewater to neutralize acidic substances, adjust the pH value of the wastewater, and make it meet the discharge standards or subsequent treatment requirements. At the same time, it can also cause certain heavy metal ions to form hydroxide precipitates, which are easy to separate and remove, reducing the heavy metal content in the wastewater. However, solid particles in calcium oxide suspension are prone to precipitation and agglomeration, which can easily cause blockages in pipes and nozzles. In addition, they are also easy to adhere to the inside of the storage tank and are difficult to clean.

[0004] To address these issues, this invention provides a calcium oxide suspension addition device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a calcium oxide suspension addition device, which solves the aforementioned problems.

The bottom of each set of cleaning heads extends into the interior of the storage chamber, and the spray direction is towards the inner wall of the storage chamber. The tee is also sealed to a third connecting pipe, and the other end of the third connecting pipe is sealed to the circular pipe. An external connecting pipe is provided at the rear end of the storage chamber, and the external connecting pipe is sealed to the third connecting pipe.

[0012] Beneficial effects

[0013] This invention provides a device for adding calcium oxide suspension. Compared with the prior art, it has the following advantages:

[0014] When the stored suspension has been left for a long time, the device uses a screw conveyor and stirring rod to agitate the calcium oxide suspension at the bottom of the storage chamber, making the suspension more uniform and reducing sedimentation. The amount of calcium oxide suspension can be controlled by opening and closing the solenoid valve on the control panel. The device also features a circular pipe, cleaning head, first solenoid water valve, and second solenoid water valve to clean the inner wall of the storage chamber and the nozzle, reducing the likelihood of nozzle clogging and improving the device's usability.

[0020] 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.

[0021] Example 1:

[0022] Please see Figure 1-4 A calcium oxide suspension addition device includes a storage chamber 1, a transfer chamber 3 located directly below the storage chamber 1, a connecting pipe 2 connecting the storage chamber 1 and the transfer chamber 3, and a solenoid valve 4 fixedly installed on the connecting pipe 2. A feed hopper 5 is fixedly installed at the top of the storage chamber 1, a motor 6 is fixedly installed at the middle of the top of the storage chamber 1, a rotating shaft 7 is fixedly installed at the output end of the motor 6, the other end of the rotating shaft 7 extends into the interior of the connecting pipe 2, a spiral auger 9 is fixedly installed at the bottom of the outer wall of the rotating shaft 7, and several sets of stirring rods 8 are also fixedly installed on the rotating shaft 7.

[0023] An installation chamber 11 is fixedly installed on the outer right side of the transfer chamber 3. Several sets of nozzles 12 are fixedly installed on the outer right side of the installation chamber 11. A pump body 10 is fixedly installed at the bottom inside the transfer chamber 3. A first connecting pipe 14 is fixedly installed at the output end of the pump body 10. A tee 13 is sealed to the other end of the first connecting pipe 14. A second connecting pipe 15 is sealed to the installation chamber 11. The other end of the second connecting pipe 15 is sealed to the tee 13.

[0024] A control panel 22 is fixedly installed on the outer wall of the front end of the storage compartment 1. The solenoid valve 4, motor 6, pump body 10, first solenoid water valve 19 and second solenoid water valve 20 are all electrically connected to the control panel 22.

[0025] Rubber pads 23 are fixedly installed at the four corners of the bottom of storage compartment 1.

[0026] When the calcium oxide suspension stored in storage chamber 1 is left for a long time, sediment will inevitably form at the bottom of storage chamber 1. In this case, the operator can start the motor 6 set in the control panel 22, so that the stirring rod 8 can stir the suspension and the screw conveyor 9 can rotate at the same time. This can turn the suspension and sediment at the bottom of storage chamber 1 upward, so that the stirred suspension is more uniform and can effectively reduce sedimentation. Then, the amount of calcium oxide suspension entering the transfer chamber 3 can be controlled by opening and closing the solenoid valve 4 set in the control panel 22, so that the actual use of this device is more advanced. In addition, in this device, by setting up the installation chamber 11 and several sets of nozzles 12, the suspension can be added to the target wastewater in a multi-point spray pattern, which improves the mixing reaction efficiency of the suspension and the target wastewater to a certain extent.

[0027] Example 2:

[0028] Please see Figure 1-4 This embodiment provides a technical solution based on embodiment one: A circular pipe 16 is fixedly installed at the top of the storage chamber 1, and several sets of cleaning heads 17 are fixedly installed at the bottom of the circular pipe 16. The bottom of each set of cleaning heads 17 extends into the storage chamber 1, and the spray direction is towards the inner wall of the storage chamber 1. A third connecting pipe 18 is also sealed to the tee 13. The other end of the third connecting pipe 18 is sealed to the circular pipe 16. An external pipe 21 is provided at the rear end of the storage chamber 1, and the external pipe 21 is sealed to the third connecting pipe 18.

[0029] A first electromagnetic water valve 19 is fixedly installed on the first connecting pipe 14, and a second electromagnetic water valve 20 is fixedly installed on the third connecting pipe 18.

[0030] When the device is finished and needs to be cleaned, the operator can open the solenoid valve 4 and the second solenoid water valve 20 through the control panel 22 while closing the first solenoid water valve 19. Then, connect the external pipe 21 to a high-pressure water source so that the water can pass through the circular pipe 16 and spray out through the cleaning head 17, which can effectively rinse the inner wall of the storage chamber 1. At the same time, the water can also pass through the third connecting pipe 18 and the installation chamber 11 and spray out from the nozzle 12, thereby reducing the occurrence of nozzle clogging and making the device more usable.
