Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a high-concentration wastewater pretreatment device. Background Technology

[0002] Wastewater refers to water containing pollutants after use, which may originate from industrial production, agricultural irrigation, domestic sewage, etc. High-concentration wastewater refers to wastewater containing high concentrations of pollutants. A pretreatment device is a piece of equipment or system that pre-treats wastewater before it enters the main wastewater treatment system. Its main purpose is to remove particulate matter, suspended solids, dissolved substances, etc., from the wastewater before further treatment, thereby reducing the load on downstream equipment and protecting its normal operation.

[0018] A further technical improvement of the present invention is that each reactant comprises:

[0019] The feed pipe is vertically and slidably installed on the top of the transfer box;

[0020] A feed nozzle is installed at the bottom end of the feed pipe and is located inside the transfer box.

[0021] A further technical improvement of the present invention is that the linear adjustment member includes:

[0022] A telescopic motor, which is vertically mounted outside the transmission box;

[0023] A connecting block is provided at the telescopic end of the telescopic motor and is sleeved outside the feed pipe.

[0024] A further technical improvement of the present invention is that: the transmission box is provided with multiple air outlet pipes, the multiple air outlet pipes are arranged vertically, and the multiple air outlet pipes are all connected to the interior of the transmission box.

[0025] A further technical improvement of the present invention is that: a stationary box is provided at the bottom of the transmission box, and mounting blocks are provided on both sides of the stationary box. The mounting blocks are provided with threaded holes for connecting to the transmission box, and threaded fixing pins are provided in the threaded holes.

[0026] A further technical improvement of the present invention is that the purification component includes:

[0027] A filter membrane, which is fitted onto the inlet end of the purification cylinder;

[0028] Multiple activated carbon adsorption plates are vertically arranged in sequence inside the purification cylinder.

[0029] The purification cylinder is equipped with an external mounting frame, on which a lifting screw is vertically and rotatably mounted. The mounting frame is equipped with an adjustment motor that drives the lifting screw to rotate. A mounting plate is threaded onto the lifting screw, and multiple activated carbon adsorption plates are detachably mounted on the mounting plate.

[0030] A rotating cylinder, which is rotatably installed inside a purification cylinder;

[0031] The rotating cylinder has multiple isolation plates arranged inside its rotation axis, and multiple openings are provided on the outside of the rotating cylinder, with each opening corresponding to a different isolation plate.

[0032] A further technical improvement of the present invention is that the driving component includes:

[0033] A drive pump is installed inside the purification cylinder;

[0034] Multiple outlet pipes are installed at the outlet end of the purification cylinder.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] (1) This device filters larger sediments in wastewater through multiple inclined filter plates. The larger sediments move along the inclined filter plates to the bottom of the sedimentation chamber, completing the initial filtration process of the wastewater. The filtered wastewater then enters the transfer box. External oxidizing liquid is added to the wastewater in the transfer box through the feed pipe and feed nozzle, causing the oxidizing liquid to react fully with the wastewater. This facilitates the chemical reaction of the oxidizing liquid with the wastewater, thus facilitating the purification of the wastewater. The telescopic motor drives the connecting block, feed pipe, and feed nozzle to move vertically along the inside of the transfer box, thereby adjusting the position of the feed nozzle in the transfer box and bringing the oxidizing liquid into contact with different parts of the wastewater, thus facilitating the full oxidation of the wastewater.

[0037] (2) After the wastewater passes through the transfer box, it will pass through the filter membrane, which will intercept the fine substances in the wastewater, thus improving the purification effect of the wastewater. The wastewater passing through the filter membrane will reach the purification cylinder, where multiple activated carbon adsorption plates will adsorb and fix the pollutants in the wastewater. There will be a microbial community in the rotating cylinder, which will biologically purify the pollutants adsorbed by the activated carbon adsorption plates, thereby improving the purification effect of the wastewater. The external drive device can drive the purification cylinder to rotate, so that the wastewater will sequentially reach the small spaces isolated by multiple isolation plates, thus facilitating the wastewater to fully contact the microorganisms in each small space and improving the purification effect of the wastewater.

[0038] (3) When larger sediments move along the filter inclined plate to the bottom of the sedimentation chamber, the sediments fall into the collection box. The electric push rod drives the connecting rod, the collection box and the sediments inside to move out of the treatment box, thus facilitating the centralized treatment of sediments. When wastewater reacts with oxidizing liquid and produces gas, the gas produced will flow to the outside of the transfer box through multiple gas outlet pipes, thus ensuring normal gas pressure in the transfer box and ensuring sufficient reaction between wastewater and oxidizing liquid. When wastewater reacts with the wastewater in the transfer box, the resulting sediments will reach the stationary box at the bottom of the transfer box, allowing the stationary box to collect the sediments. The stationary box and the sediments inside can be easily removed from the transfer box by the threaded fixing pin and the mounting block, thus facilitating the centralized treatment of sediments.

[0046] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0047] Please see Figures 1-5 As shown, this invention proposes a high-concentration wastewater pretreatment device, comprising: a treatment tank 1, wherein a sedimentation chamber is provided inside the treatment tank 1; wherein a filter element 2 is provided inside the sedimentation chamber, and the filter element 2 is inclined; a transfer tank 3, which is connected to one side of the treatment tank 1; wherein a plurality of reaction elements 4 are provided on the transfer tank 3, and a plurality of linear adjustment elements 5 are provided inside the transfer tank 3 to drive the plurality of reaction elements 4 to move vertically; a purification cylinder 6, which is horizontally arranged on the side of the transfer tank 3 away from the treatment tank 1, and the purification cylinder 6 is connected to the transfer tank 3; wherein a purification element 7 is provided inside the purification cylinder 6, and a driving element 8 is provided inside the purification cylinder 6; wastewater is introduced into the treatment tank 1, and larger sediments in the wastewater are filtered through the filter element 2, and the larger sediments slide along the inclined surface of the filter element 2. The filtration process continues until the sediment settles to the bottom of the sedimentation chamber in treatment tank 1, completing the filtration process. The filtered wastewater then reaches transfer tank 3, where multiple reaction elements 4 introduce oxidizing liquid, facilitating a chemical reaction between the oxidizing liquid and the wastewater, thus facilitating wastewater purification. Multiple linear adjustment elements 5 move multiple reaction elements 4 to corresponding positions within transfer tank 3, allowing the oxidizing liquid to react with wastewater at different locations, improving the wastewater purification effect. When the wastewater reaches purification cylinder 6 through transfer tank 3, purification elements 7 perform microbial purification on purification cylinder 6. The microorganisms react with organic matter and salt solutions in the wastewater, thus purifying the wastewater. The drive element 8 drives the water flow within purification cylinder 6, thereby improving the wastewater purification efficiency.

[0048] Each filter element 2 includes: multiple filter inclined plates 201, which are sequentially arranged in the sedimentation chamber, with the bottom end of the filter inclined plates 201 away from the transfer box 3; and a filter screen sleeve 202, which is fitted inside the feed inlet of the transfer box 3 and is located inside the sedimentation chamber. The multiple filter inclined plates 201 are used to filter larger sediments in the wastewater, and the larger sediments will move along the filter inclined plates 201 to the bottom of the sedimentation chamber, completing the initial filtration process of the wastewater.

[0049] A collection box 9 is horizontally slidably installed inside the treatment box 1, and the collection box 9 is located at the bottom of the sedimentation chamber. Multiple electric push rods 10 are horizontally arranged on the treatment box 1. The telescopic end of the electric push rod 10 is provided with a connecting rod 11, which is connected to the collection box 9. When larger sediments move to the bottom of the sedimentation chamber along the filter inclined plate 201, the sediments will fall into the collection box 9. The electric push rods 10 drive the connecting rod 11, the collection box 9 and the sediments inside to move out of the treatment box 1, thereby facilitating the centralized treatment of sediments.

[0050] Each reaction element 4 includes: a feed pipe 401, which is vertically slidably mounted on the top of the transfer box 3; and a feed nozzle 402, which is mounted on the bottom end of the feed pipe 401 and located inside the transfer box 3. External oxidizing liquid is added to the wastewater in the transfer box 3 through the feed pipe 401 and the feed nozzle 402, so that the oxidizing liquid and the wastewater react fully.

[0051] The linear adjustment component 5 includes: a telescopic motor 501, which is vertically installed outside the transmission box 3; and a connecting block 502, which is installed at the telescopic end of the telescopic motor 501 and is sleeved on the outside of the feed pipe 401. The telescopic motor 501 drives the connecting block 502, the feed pipe 401, and the feed nozzle 402 to move vertically along the inside of the transmission box 3, thereby adjusting the position of the feed nozzle 402 inside the transmission box 3, so as to bring the oxidizing liquid into contact with different parts of the wastewater, thereby facilitating the full oxidation treatment of the wastewater.

[0052] The transfer box 3 is equipped with multiple air outlet pipes 12, which are arranged vertically and are all connected to the interior of the transfer box 3. When the wastewater reacts with the oxidizing liquid and generates gas, the generated gas will flow to the outside of the transfer box 3 through the multiple air outlet pipes 12, thereby ensuring the normal gas pressure inside the transfer box 3 and thus ensuring the full reaction of the wastewater and the oxidizing liquid.

[0053] The bottom of the transfer box 3 is equipped with a stationary box 13, and both sides of the stationary box 13 are equipped with mounting blocks 14. The mounting blocks 14 are provided with threaded holes that connect to the transfer box 3, and threaded fixing pins 15 are provided in the threaded holes. When the wastewater reacts with the wastewater in the transfer box 3, the resulting sediment will reach the stationary box 13 at the bottom of the transfer box 3, so that the stationary box 13 can collect the sediment. The stationary box 13 and the sediment inside it can be easily removed from the transfer box 3 by means of the threaded fixing pins 15 and the mounting blocks 14, so as to facilitate the centralized treatment of the sediment.

[0054] The purification component 7 includes: a filter membrane 701, which is fitted onto the inlet end of the purification cylinder 6; multiple activated carbon adsorption plates 702, which are vertically arranged sequentially inside the purification cylinder 6; wherein, the purification cylinder 6 is provided with a mounting frame 16, on which a lifting screw 17 is vertically rotatably mounted, and a regulating motor 18 is provided on the mounting frame 16 to drive the lifting screw 17 to rotate; a mounting plate 19 is threaded onto the lifting screw 17, and the multiple activated carbon adsorption plates 702 are detachably mounted on the mounting plate 19; and a rotating cylinder 703, which is rotatably installed inside the purification cylinder 6; wherein, multiple isolation plates 20 are provided inside the rotating cylinder 703 along its rotation axis, and multiple openings 21 are provided on the outside of the rotating cylinder 703, which are respectively connected to multiple isolation plates 20. Corresponding to the isolation plate 20; after the wastewater passes through the transfer box 3, it passes through the filter membrane 701, which intercepts fine substances in the wastewater, thus improving the purification effect. The wastewater passing through the filter membrane 701 reaches the purification cylinder 6, where multiple activated carbon adsorption plates 702 adsorb and fix pollutants in the wastewater. The rotating cylinder 703 contains a microbial community, which biologically purifies the pollutants adsorbed by the activated carbon adsorption plates 702, thereby improving the purification effect of the wastewater. An external drive device can drive the purification cylinder 6 to rotate, so that the wastewater sequentially reaches the small spaces isolated by multiple isolation plates 20, which facilitates the wastewater to fully contact the microorganisms in each small space, improving the purification effect of the wastewater.

[0055] The driving component 8 includes: a driving pump 801, which is installed inside the purification cylinder 6; and multiple outlet pipes 802, which are installed at the outlet end of the purification cylinder 6. After the wastewater reaction is completed, the driving pump 801 drives the purified water in the purification cylinder 6 to flow and flows out through the multiple outlet pipes 802, thereby improving the effluent efficiency of the purified water.

[0056] In use, wastewater is introduced into the treatment tank 1. Larger sediments in the wastewater are filtered through multiple inclined filter plates 201, which move along the inclined plates 201 to the bottom of the sedimentation chamber, completing the initial filtration process. When the larger sediments reach the bottom of the sedimentation chamber, they fall into the collection tank 9. An electric push rod 10 then moves the connecting rod 11, the collection tank 9, and the sediments inside out of the treatment tank 1, facilitating centralized treatment. The filtered wastewater then reaches the transfer tank 3. External oxidizing liquid is added to the wastewater in the transfer tank 3 through the feed pipe 401 and feed nozzle 402, allowing the oxidizing liquid to fully react with the wastewater, facilitating the chemical reaction between the oxidizing liquid and the wastewater, thus facilitating wastewater purification. The process is further enhanced by the telescopic motor 501. The connecting block 502, feed pipe 401, and feed nozzle 402 move vertically along the inside of the transfer box 3, thereby adjusting the position of the feed nozzle 402 within the transfer box 3. This allows the oxidizing liquid to contact different parts of the wastewater, facilitating thorough oxidation treatment of the wastewater. When the wastewater reacts with the oxidizing liquid and generates gas, the generated gas flows to the outside of the transfer box 3 through multiple gas outlet pipes 12, ensuring normal gas pressure within the transfer box 3 and thus ensuring thorough reaction between the wastewater and the oxidizing liquid. When the wastewater reacts with the wastewater in the transfer box 3, the resulting sediment reaches the stationary box 13 at the bottom of the transfer box 3, where the stationary box 13 collects the sediment. The stationary box 13 and the sediment within it can be easily removed from the transfer box 3 using threaded fixing pins 15 and mounting blocks 14, facilitating centralized treatment of the sediment.

[0057] After the wastewater passes through the transfer box 3, it passes through the filter membrane 701, which intercepts fine particles in the wastewater, thus purifying it. The wastewater then reaches the purification cylinder 6, where multiple activated carbon adsorption plates 702 adsorb and fix pollutants. A microbial community within the rotating cylinder 703 biologically purifies the pollutants adsorbed by the activated carbon adsorption plates 702, further enhancing the purification effect. An external drive unit rotates the purification cylinder 6, allowing the wastewater to sequentially reach the individual spaces separated by multiple isolation plates 20, facilitating thorough contact between the wastewater and the microorganisms in each space and improving the purification effect. After the wastewater reaction is complete, a drive pump 801 circulates the purified water within the purification cylinder 6, which then flows out through multiple outlet pipes 802, improving the effluent efficiency.
