Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, specifically to a skid-mounted super disk water treatment device. Background Technology

[0002] Currently used wastewater treatment equipment typically treats wastewater through magnetic separation. However, the current method relies solely on magnetic drum separators to recover the magnetic seeds, resulting in low impurity removal rates and increased wastewater treatment costs. Furthermore, existing wastewater treatment equipment usually requires significant space, making it difficult to implement in areas with limited land resources, such as mines. Utility Model Content

[0003] The purpose of this invention is to provide a skid-mounted super disk water treatment device that solves the problems of low impurity removal rate and low magnetic seed recovery rate in current sewage treatment equipment.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A skid-mounted super disk water treatment device includes a skid-mounted compartment with doors at the front and rear ends and on the left and right sides. The compartment contains a primary mixing tank, a secondary mixing tank, a tertiary mixing tank, a disk separator, and a magnetic drum separator. The primary mixing tank has a wastewater inlet. The primary, secondary, and tertiary mixing tanks are connected in sequence. The tertiary mixing tank is connected to the disk separator through a water-passing square pipe. The disk separator is connected to the mixing tank and the magnetic drum separator in sequence through a sludge inlet pipe. One end of the magnetic drum separator is connected to the sludge tank through a sludge pipe, and the other end is connected to the secondary mixing tank through a magnetic seed addition pipe.

[0006] Furthermore, each of the primary mixing tank, secondary mixing tank, tertiary mixing tank, and stirring tank is equipped with a mixer.

[0007] Furthermore, the disk separator is equipped with a mixed water inlet, a clean water outlet, and a mixed flocculent outlet; the mixed water inlet is connected to a water-passing square pipe, the clean water outlet is connected to the water outlet of the skid-mounted compartment, and the mixed flocculent outlet is connected to the mixing tank through a mud inlet pipe.

[0008] Furthermore, the disk separator includes an adsorption disk and a scraper. The adsorption disk is equipped with a drive motor, which drives the adsorption disk to rotate. The scraper is inclinedly disposed on the disk.

[0009] Furthermore, the skid-mounted compartment is also equipped with a PAC preparation device and a PAM preparation device. The PAC preparation device is equipped with a PAC dosing metering pump, and the PAM preparation device is equipped with a PAM dosing metering pump.

[0012] Furthermore, the middle part of the mud inlet pipe is inclined.

[0013] By adopting the above technical solution, the beneficial technical effects of this utility model are:

[0014] This invention treats wastewater by sequentially passing it through a primary, secondary, and tertiary mixing tank. First, a magnetic separator adsorbs flocs from the water onto magnetic disks, preventing magnetic seeds from being carried away with the clean water from the flocs produced in the tertiary mixing tank. Then, scrapers in the magnetic separator scrape the flocs off the disks and transport them to a mixing tank. A mixer in the mixing tank breaks up the synthesized flocs, and a magnetic drum separator re-adsorbs the magnetic seeds. Finally, the magnetic seeds are added to the secondary mixing tank through a magnetic seed dosing pipe. This invention effectively improves the magnetic seed recovery rate and significantly reduces wastewater treatment costs. Attached Figure Description

[0016] Figure 2 This is a schematic diagram of a disk splitter. Detailed Implementation

[0017] like Figure 1As shown, a skid-mounted super disk water treatment device includes a skid-mounted compartment 1, which is square in shape. Doors 11 are installed at the front and rear ends and on the left and right sides of the skid-mounted compartment 1. The compartment 1 contains a primary mixing tank 2, a secondary mixing tank 3, a tertiary mixing tank 4, a disk separator 5, and a magnetic drum separator 6. The skid-mounted compartment 1 is provided with a water inlet 7, and the primary mixing tank 2 is provided with a sewage inlet 8. The water inlet 7 and the sewage inlet 8 are connected. Sewage enters the primary mixing tank 2 after passing through the water inlet 7 and the sewage inlet 8 in sequence. Aluminum salt or iron salt coagulant is added to the primary mixing tank 2 to destabilize the suspended solids and colloidal particles in the raw water. The primary mixing tank 2, the secondary mixing tank 3, and the tertiary mixing tank 4 are connected in sequence. PAM and PAC agents are added to the secondary mixing tank 3 to accelerate the adsorption capacity of suspended solids and colloidal particles in the raw water. The tertiary mixing tank 4 allows the flocs to adsorb each other, forming larger and heavier flocs for easier treatment. The tertiary mixing tank 4 is connected to the disk separator 5 via a water-passing square pipe 9. The disk separator 5 uses magnetic force to adsorb the flocs carrying magnetic seeds onto the disk. The disk separator 5 is then connected to the mixing tank 12 and the magnetic drum separator 6 via the sludge inlet pipe 10. Under the action of scrapers, the flocs carrying magnetic seeds adsorbed on the disk are sent to the magnetic drum separator 6. The mixing tank 12 breaks up the flocs, and the magnetic drum separator 6 uses magnetic force to adsorb the magnetic seeds and adds them to the secondary mixing tank 2 through the magnetic seed addition pipe. The non-magnetic flocs are transported to the sludge tank through the sludge pipe. This device uses the disk separator 5 to adsorb all the flocs carrying magnetic seeds onto the disk, achieving the goal of full reuse of all magnetic seeds and reducing the cost of using magnetic seeds. Finally, the magnetic seeds are added to the primary mixing tank 2 through the magnetic drum separator 6 via the magnetic seed addition pipe.

[0018] The primary mixing tank 2, secondary mixing tank 3, tertiary mixing tank 4, and stirring tank 12 are each equipped with a mixer 13. In the primary mixing tank 2, the mixer 13 rapidly agitates the water after it enters and aluminum or iron salt coagulants are added, accelerating the destabilization of suspended solids and colloidal particles, allowing the raw water to remain in the mixing tank 1 for approximately 1-2 minutes. In the secondary mixing tank 3, the mixer 13 rapidly agitates the water after it enters and PAC and PAM are added, accelerating the reaction between PAC and PAM and suspended solids and colloidal particles in the raw water to form flocs. In the tertiary mixing tank 4, the agitation intensity of the mixer 13 is lower than that of the mixers 13 in the primary and secondary mixing tanks 2 and 3, maintaining the flocs in suspension while preventing the already formed flocs from being destroyed.

[0019] like Figure 2As shown, the disk separator 5 is provided with a mixed water inlet 51, a clean water outlet 52 and a mixed flocculent outlet 53; the mixed water inlet 51 is connected to the water passage square pipe 9, the clean water outlet 52 is connected to the water outlet of the skid-mounted compartment 1, and the mixed flocculent outlet 53 is connected to the mixing tank 12 through the mud inlet pipe 10. Raw water containing flocculent particles enters the disk separator 5 through the mixed water inlet 51. The disk separator 5 includes an adsorption disk 54 and a scraper 55. The adsorption disk 54 is equipped with a drive motor, which drives the adsorption disk 54 to rotate. The scraper 55 is inclined on the adsorption disk 54 at a 45° angle. The adsorption disk 54 adsorbs the flocculent particles containing magnetic seeds. The lower end of the scraper 55 abuts against the top of the mixed flocculent outlet 53, making it easier for the scraper 55 to scrape the flocculent particles containing magnetic seeds off the adsorption disk 54 and into the mixed flocculent outlet 53. The scraper 55 itself is inclined, and the flocculent particles containing magnetic seeds will enter the mixed flocculent outlet 53 due to their own weight. The magnetic flocs scraped off from the adsorption disk 54 by the scraper 55 will then be transported to the mixing tank 12 through the mixed floc outlet 53 and the mud inlet pipe 10. The mud inlet pipe 10 is inclined in the middle to facilitate the magnetic flocs with their own weight to reach the mixing tank 12 more quickly. The non-magnetic water will flow out through the clean water outlet 52.

[0020] The skid-mounted compartment 1 also houses a PAC preparation device 21 and a PAM preparation device 22. The PAC preparation device 21 is equipped with a PAC metering pump, and the PAM preparation device 22 is equipped with a PAM metering pump. The PAC preparation device 21 is connected to the primary mixing tank 2, and the PAM preparation device 22 is connected to the secondary mixing tank 3. The reaction between PAC and PAM and suspended solids and colloidal particles in the raw water forms flocs, accelerating the wastewater treatment efficiency.

[0021] The skid-mounted compartment 1 is also equipped with an electrical control cabinet 23, which contains a control system. The skid-mounted compartment 1 has pre-drilled holes, and the electrical control cabinet 23 has cable outlet holes; the pre-drilled holes and cable outlet holes are aligned and connected. The control system controls the motors and valves to ensure that the equipment within the skid-mounted compartment 1 treats wastewater with maximum efficiency.

[0022] The mixing tank 12 is equipped with a water collection tank at the top, which is connected to the supernatant outlet, which is also connected to the water outlet of the skid-mounted compartment 1. The mixer 13 in the mixing tank 12 will break up the flocculent material entering the mixing tank 12. The magnetic seeds will be attracted and transported to the primary mixing tank 2 by the magnetic force of the magnetic drum separator 6. The flocculent material will then settle to form sludge, which will be transported to the sludge tank through the sludge pipe. After the flocculent material settles, the water will be located in the water collection tank at the top of the mixing tank 12 and will eventually be discharged through the supernatant outlet.

[0023] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
