Description

Technical Field

[0001] The invention relates to the technical field of wastewater purification and treatment, in particular to a self-cleaning mud-containing wastewater purification and treatment device. Background Art

[0002] Muddy wastewater usually comes from industrial production processes, urban sewage treatment, and wastewater formed after natural water bodies are polluted. Its water quality generally contains a certain amount of mud particles and pollutants. If this type of muddy wastewater is discharged directly without treatment, it will pollute the water body, affect the ecological environment and human health, so it generally needs to be purified before discharge.

[0003] After searching, it is found that sewage purification equipment is generally used to purify muddy wastewater. For example, a prior art document with patent publication number CN210030098U and IPC classification number C02F1 / 12 (20060101) discloses a muddy wastewater separation device, whose main components include a drum, a feed port, a discharge port, blades, a shell, a heater, a blower, an air inlet pipe, an air inlet hole, an air outlet pipe, medium particles, a nozzle, a belt conveyor, an elevator, a first ash hopper, a discharge machine, a second ash hopper, a sewage storage tank, and a water pump.

[0004] The above-mentioned existing sludge wastewater separation device mainly adopts drum drying to achieve sludge separation, and uses medium particles as water treatment media; it can be seen from its records that it mainly relies on the dryer to dry the surface of the medium particles, the water in the sludge wastewater placed inside the drum evaporates, and the solids condense on the surface of the medium particles, thereby realizing solid-liquid separation during water treatment.

[0005] However, in the actual operation process, the muddy wastewater will accumulate inside the drum and on the blades. During the drying process, the mud stains will be dehydrated and accumulated inside the drum, which makes it inconvenient to clean the inside of the drum during long-term operation. In addition, the direct volatilization of the wastewater by heating and evaporating the water will consume a lot of electricity. When the mud content is not large, it will also lead to problems such as a long time for mud and water separation and difficulty in evaporating the water.

[0006] Based on this, the present invention optimizes the problems existing in the prior art in the process of treating mud-containing wastewater, and designs a mud-containing wastewater purification treatment equipment that can quickly achieve self-cleaning, so as to better solve the problems existing in the prior art.

[0039] The following is a detailed description of the embodiments of the technical solution of the present invention in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present invention. Figure 1-Figure 8 as shown in .

[0040] Embodiment 1: A self-cleaning muddy wastewater purification and treatment equipment comprises two wastewater separation units spaced apart in a front-to-rear manner, the bottom of each of the wastewater separation units being fixedly mounted on the top of a bottom base 1, a multi-directional drive unit being arranged between the two wastewater separation units, the output ends at both ends of the multi-directional drive unit being respectively used to drive the wastewater separation units at their corresponding positions to operate, the power of the multi-directional drive unit being provided by an external drive component, the input power of the multi-directional drive unit being maintained in a horizontal fixed-axis rotation state in a working state, the top of each of the wastewater separation units being used to receive muddy wastewater transported from upstream, and a primary filtered water storage tank 2 being fixedly mounted at the top center of the bottom base 1 below the multi-directional drive unit.

[0041] When the self-cleaning mud-containing wastewater purification and treatment equipment of the present invention is treating mud-containing wastewater, it first uses an external pipeline to connect with the drainage riser 3 on the top of each current wastewater separation unit, and relies on the drainage riser 3 to continuously introduce the mud-containing wastewater into each wastewater separation unit, and pre-starts the multi-directional drive unit to drive each wastewater separation unit to realize low-speed rotation first so that a large amount of water in the wastewater is quickly filtered downward. After the initial filtration is completed, the wastewater separation unit is controlled to rotate at a high speed, and the residual water is quickly separated outward by high-speed centrifugation. Finally, the internal operation of the wastewater separation unit is controlled to collect the remaining high-concentration sludge fluid or semi-fluid and continue to transport it downstream; in addition, considering the stability and firmness of the entire equipment, it is necessary to control the construction of the corresponding components to be kept fixed during installation to ensure the stability of the entire structure under high-speed centrifugal state.

[0042] In any of the above schemes, it is preferred that the wastewater separation unit includes two centrifugal separation components that are spaced apart and symmetrically arranged, both of which are fixedly arranged relative to the bottom base 1, a drainage riser 3 is arranged above the centrifugal separation component, the drainage riser 3 remains fixed on a fixed axis in a working state, the lower end of the drainage riser 3 movably extends into the interior of the centrifugal separation component, the centrifugal separation component is coaxially arranged with the drainage riser 3, a primary filtration and discharge multi-purpose component is installed at the bottom of the centrifugal separation component, the bottom of the primary filtration and discharge multi-purpose component is fixed to the top of the bottom base 1, the top of the primary filtration and discharge multi-purpose component is cooperatively plugged into the bottom of the centrifugal separation component and the two rotate relative to the fixed axis, the centrifugal separation component is driven by the multi-directional drive unit that is meshed with each other, and a mud receiving unit is arranged on one side of the upper part of the primary filtration and discharge multi-purpose component, and the output end of the mud receiving unit is connected to the downstream sludge treatment station.

[0043] It can be seen that when the wastewater separation unit is working, it relies on external power transmission to continuously transport the muddy wastewater to the interior of the corresponding centrifugal separation component. The wastewater entering the centrifugal separation component will first continuously push the water liquid downward into the primary filtration and discharge multi-purpose component under the action of its own weight to achieve primary filtration. The time of self-sedimentation primary filtration can be controlled to be 30S-60S. During the primary filtration process, the multi-directional drive unit can be controlled to drive the centrifugal separation component to achieve slow rotation according to the amount of water in the wastewater, so as to further push the water liquid downward as much as possible to complete the primary filtration. The remaining muddy wastewater still containing a certain amount of water liquid will be blocked and temporarily retained in the centrifugal separation component. At this time, the centrifugal separation component is controlled to rotate at a high speed. During the high-speed rotation of the centrifugal separation component, the remaining water liquid can be quickly thrown out under the action of high-speed centrifugal force, thereby further achieving the purpose of reducing the water content. At this time, what remains in the centrifugal separation component is semi-dry sludge or high-concentration sludge. At this time, controlling the lifting and displacement of the mud receiving unit can make the remaining semi-dry sludge or high-concentration sludge directly enter the mud receiving unit and be transported downward.

[0044] In any of the above schemes, it is preferred that the centrifugal separation component includes a centrifugal filter cartridge 4 coaxially arranged below the drainage riser 3, the outer side wall surface of the centrifugal filter cartridge 4 is provided with centrifugal sieve holes for separating water and mud, a top cover 5 is provided on the top of the centrifugal filter cartridge 4, the lower end of the drainage riser 3 movably passes through the top cover 5 and extends into the centrifugal cavity inside the centrifugal filter cartridge 4, and driven gears 6 coaxially fixed thereto are installed on the upper and lower outer side walls of the centrifugal filter cartridge 4, and each of the driven gears 6 is respectively meshed with the output end of the multi-directional drive unit, the lower end of the centrifugal filter cartridge 4 is movably sleeved on the outer side wall of the top of the primary filtration and discharge multi-purpose component, and a receiving and fixing ring 7 is fixed on the lower outer side wall of the centrifugal cavity, and the bottom of the receiving and fixing ring 7 movably abuts against the top of the primary filtration and discharge multi-purpose component.

[0045] It should be noted that the centrifugal separation component adopts two states of fixed-axis low-speed rotation and high-speed rotation when working; the low-speed rotation is used to pre-shake the muddy wastewater in the initial state, and the high-speed rotation is used to throw away the excess water in the muddy wastewater.

[0046] When controlling the centrifugal filter cartridge 4 of the centrifugal separation component to achieve fixed-axis rotation, a multi-directional drive unit is required to control the corresponding driven gear 6 to rotate. When the driven gear 6 rotates, it can drive the centrifugal filter cartridge 4 to achieve fixed-axis rotation relative to the drainage riser 3 and the multi-purpose component for primary filtration and discharge. When the slow and low-speed rotation is turned on, the water liquid in the centrifugal cavity of the centrifugal filter cartridge 4 can be initially filtered downward. During the initial filtration process, the wastewater is further shaken by slow rotation, so that the water in the wastewater can be better discharged to the multi-purpose component for primary filtration and discharge at the lower part, and finally drained into the interior of the primary filtration water storage tank 2.

[0047] In a normal installation state, since the receiving fixing ring 7 abuts against the top of the primary filter and discharge multi-purpose component, and the centrifugal filter cartridge 4 is sleeved on the upper outer side of the primary filter and discharge multi-purpose component, the centrifugal filter cartridge 4 can maintain its own stability when rotating.

[0048] The receiving and fixing ring 7 may be made of brass or a bottom support bearing to ensure that it plays a labor-saving guiding role during the rotation process.

[0049] In addition, the pore size of the centrifugal sieve filter holes can be selected according to the screening requirements. The centrifugal filter cartridge 4 belongs to the existing structure and will not be described in detail.

[0050] In any of the above schemes, it is preferred that a hydraulic self-cleaning component is arranged between the two centrifugal separation components, the water inlet end of the hydraulic self-cleaning component is connected to the discharge end of the primary filtration and discharge multi-purpose component, and the water outlet end of the primary filtration and discharge multi-purpose component is connected to the interior of the primary filtration water storage tank 2.

[0051] The hydraulic self-cleaning component arranged here can centrally collect the preliminarily filtered water liquid separated and dripping downward after the initial dehydration of each centrifugal separation component. When the hydraulic self-cleaning component processes the water liquid preliminarily filtered out of the wastewater, the preliminarily filtered water storage unit can centrally collect the preliminarily filtered water liquid and use part of the preliminarily filtered water liquid as the transmission medium for subsequent reverse cleaning.

[0052] In any of the above schemes, it is preferred that the multi-purpose component for primary filtration and discharge includes a rigid vertical cylinder 8 vertically arranged directly below the centrifugal filter cylinder 4, a liquid collecting bin 801 is arranged inside the rigid vertical cylinder 8, the upper part of the rigid vertical cylinder 8 is movably inserted into and abuts against the lower inner wall of the centrifugal chamber and the two are relatively rotated, and a primary filtration water discharge pipe 9 with a valve connected thereto is arranged at the lower part of the rigid vertical cylinder 8, the two ends of the primary filtration water discharge pipe 9 are respectively fixedly connected to the rigid vertical cylinder 8 at the corresponding positions and the interiors of the two are connected, the middle part of the primary filtration water discharge pipe 9 is connected to the interior of the primary filtration water storage tank 2 through a connecting pipe 10 equipped with a two-way pump, and the central top of the primary filtration water discharge pipe 9 is fixedly connected to the hydraulic self-cleaning component.

[0053] The primary filter discharge multi-purpose component is used to collect the primary filter water liquid that flows out after preliminary screening at the bottom of the centrifugal filter cartridge 4 when it is working, and can discharge the semi-dry sludge remaining inside the centrifugal filter cartridge 4 after centrifugation into the sludge receiving unit. The muddy wastewater accumulated at the bottom of the centrifugal filter cartridge 4 will cause its water liquid to flow downward continuously under the self-weight and the screening effect inside the primary filter discharge multi-purpose component, and the mud material is blocked inside the centrifugal filter cartridge 4. The water liquid flows downward into the liquid collecting bin 801 and is continuously collected. At the same time, it is continuously transported to the interior of the primary filter water storage tank 2 through the primary filter water discharge pipe 9 and the connecting pipe 10 on one side, and then collected and settled again. At the same time, a part of it is used as the pressure transmission medium of the hydraulic self-cleaning component, and is used to control the hydraulic self-cleaning component to scrape and self-clean the outer wall of the centrifugal filter cartridge 4 of the centrifugal separation component on both sides, thereby ensuring the cleanliness of the surface of the centrifugal filter cartridge 4 and the sieve holes.

[0054] In any of the above schemes, it is preferred that the sludge receiving unit includes a sludge discharge channel 11 fixedly arranged on the upper outer wall of the rigid vertical cylinder 8, and a lifting and receiving mechanism is installed inside the liquid collecting bin 801, the interior of the sludge discharge channel 11 is connected with the upper part of the liquid collecting bin 801 above the lifting and receiving mechanism, the discharge end of the sludge discharge channel 11 is inclined downward, the discharge end of the sludge discharge channel 11 is fixedly connected to the feed port of a horizontally arranged screw conveyor 12, and the discharge end of the screw conveyor 12 is connected to the downstream sludge treatment station.

[0055] It should be noted that the sludge receiving unit is mainly used to collect and discharge the semi-dry sludge after high-speed centrifugal dehydration. During discharge, the waterproof vibration motor fixedly installed on the upper part of the outer wall of the rigid vertical cylinder 8 is controlled to vibrate, so that the semi-dry sludge accumulated in the collecting bin and the centrifugal chamber can flow quickly along the top of the lifting and receiving mechanism to its inclined section, and finally enter the screw conveyor 12 through the sludge discharge channel 11 and continue to complete the downstream processing process of the semi-dry sludge.

[0056] In any of the above schemes, it is preferred that the lifting and material-carrying mechanism includes a waterproof multi-stage lifting cylinder 13 vertically installed at the central bottom of the liquid collecting bin 801, and a columnar receiving plate 14 is quickly installed on the top of the piston rod of the multi-stage lifting cylinder 13. The end of the columnar receiving plate 14 facing the sludge discharge channel 11 is lower than the end away from the sludge discharge channel 11 and an inclined material guiding surface 1401 is formed on its surface.

[0057] In any of the above schemes, it is preferred that when the multi-stage lifting cylinder 13 controls the columnar receiving plate 14 to continuously move upward and enter the centrifugal chamber, the outer wall of the columnar receiving plate 14 cooperates with the inner wall of the centrifugal chamber to tightly press against and complete the scraping self-cleaning treatment of the interior and inner surface of the centrifugal chamber, and cooperates with the external scraping of the scraper ring 31 to complete the internal and external rapid self-cleaning treatment.

[0058] In any of the above schemes, it is preferred that a plurality of lower filtering channels 15 for allowing water to pass through and preventing mud from passing through are provided on the top surface of the inclined material guide surface 1401. The water in the wastewater accumulated in the centrifugal chamber will quickly flow downward to the lower part of the liquid collecting bin 801 during the sedimentation process to complete the initial filtration of the mud-containing wastewater.

The output end of the bevel gear transmission box on the right side is fixedly connected to the motor shaft of a fixedly arranged waterproof total drive motor 17. When the total drive motor 17 is running, it can drive the bevel gear transmission box to operate. Transmission pinions 18 are respectively installed at the upper output end and the lower output end of each bevel gear transmission box, and the front and rear sides of the transmission pinion 18 are respectively meshed with the driven gear 6 at its corresponding position.

[0061] In any of the above schemes, it is preferred that each multi-directional drive unit relies on a single total drive motor 17 as the total driving force during centrifugal drive rotation. The single power can effectively drive the eight driven gears 6, and then complete the stable fixed-axis high-speed rotation drive of the four centrifugal filter cartridges 4. The upper and lower parts of each centrifugal filter cartridge 4 are equipped with driven gears 6, which can effectively ensure the stability of the force on the centrifugal filter cartridge 4 during the entire transmission process.

[0062] In any of the above schemes, it is preferred that the bevel gear transmission box includes a fixedly installed bevel gear box body 19, and a vertical double transmission shaft 21 is arranged in the gear installation cavity 20 of the bevel gear box body 19, and the upper and lower ends of the vertical double transmission shaft 21 are passed through the upper output end and the lower output end and are respectively fixedly connected to the transmission pinion 18, and a bottom bevel gear 22 is fixedly connected to the outer wall of the vertical double transmission shaft 21 in the gear installation cavity 20, and an inner lateral bevel gear 23 and an outer lateral bevel gear 24 are respectively meshed on both sides of the bottom bevel gear 22, the inner lateral bevel gear 23 is fixedly connected to the corresponding end of the transmission main shaft 16, and the outer lateral bevel gear 24 is connected to the total drive motor 17 at its corresponding position.

[0063] The bevel gear transmission box receives the transmission force from the main drive motor 17 and completes rapid multi-directional power output during the transmission process by reversing the bottom bevel gear 22, the inner lateral bevel gear 23, and the outer lateral bevel gear 24, thereby ensuring the multi-directionality of the transmission and the high efficiency of the driving centrifugal operation.

[0064] Embodiment 3: Compared with Embodiment 2, this embodiment is different in that it also includes the following technical features:

[0065] In any of the above schemes, it is preferred that the hydraulic self-cleaning component includes a vertically arranged pressure delivery riser 25, on which a bidirectional power pump 26 is arranged, and the bidirectional power pump 26 can realize bidirectional liquid delivery, the bottom of the pressure delivery riser 25 is fixed to the middle section of the primary filtered water discharge pipe 9 and the two are internally connected, an inverted U-shaped tube 27 connected to the interior is fixedly installed on the top of the pressure delivery riser 25, and plunger columns 28 are respectively sealed and inserted in the plunger tube cavities of the two vertical pipe sections 2701 of the inverted U-shaped tube 27, the bottom of each plunger column 28 is fixed to the top of a horizontally arranged filter connecting beam 29, and a constraint guide riser 30 is integrally formed in the middle of the filter connecting beam 29, the constraint guide riser 30 is movably sleeved on the outer side wall of the pressure delivery riser 25, and scraper rings 31 are respectively fixedly installed on the left and right ends of the filter connecting beam 29, and each scraper ring 31 is sleeved on the outer side wall of the centrifugal filter cartridge 4 at its corresponding position.

[0066] When the centrifugal filter cartridge 4 is used for a long time, there will be a lot of mud residue or blockage caused by splashing mud and water on the outer surface, so it needs to be cleaned regularly. The scraper ring 31 added here can make its inner wall abut against the outer wall of the centrifugal filter cartridge 4, and the two-way power pump 26 is started to drive the primary filtered water liquid transported from the bottom to fill the two vertical pipe sections 2701 of the inverted U-shaped tube 27, so as to form a plunger structure. Under the downward pressure of the water, the plunger column 28 will continue to move downward. In the process of the plunger column 28 moving downward, it can move the filter connecting beam 29 at the bottom downward, thereby driving the scraper rings 31 on both sides connected to it to complete the scraping process downward.

[0067] During the downward translation of the filtering connecting beam 29, the central constraint guide riser 30 can ensure the stability of the downward displacement, reduce the probability of deviation, ensure the vertical downward pushing displacement, ensure the centering effect of the scraper ring 31 moving up and down, improve the scraping effect, and reduce the probability of deviation and jamming.

[0068] In any of the above schemes, it is preferred that return springs 32 are vertically arranged on the left and right sides of the pressure delivery riser 25 on both sides of the constraint guide riser 30, respectively, and the lower end of each return spring 32 is fixed to the top of the filter connecting beam 29, and the top of each return spring 32 is fixed to the bottom of the horizontal section of the inverted U-shaped tube 27.

[0069] The two return springs 32 are mainly used to pull the plunger 28 upward to return. When the power of the two-way power pump 26 is reversed or disappears, the elastic force of the return spring 32 can be used to control the stable upward return of the plunger 28, thereby ensuring the continuity of the entire self-cleaning effect.

[0070] Specific working principle: When working, first use the external pipeline to connect with the drainage riser 3 on the top of each current wastewater separation unit, and rely on the drainage riser 3 to continuously introduce muddy wastewater into each wastewater separation unit.

[0071] The multi-directional drive unit is started in advance to drive each wastewater separation unit to rotate at a low speed first so that a large amount of water in the wastewater can be quickly filtered downward. After the initial filtration is completed, the wastewater separation unit is controlled to rotate at a high speed, and the residual water is quickly separated outward by high-speed centrifugation. Finally, the internal operation of the wastewater separation unit is controlled to collect the remaining high-concentration sludge fluid or semi-fluid and continue to transport it downstream.

[0072] Considering the stability and firmness of the whole equipment, it is necessary to control the construction of corresponding components to remain fixed during installation to ensure the stability of the whole structure under high-speed centrifugal state.

[0073] The centrifugal separation component adopts two states when working: fixed-axis low-speed rotation and high-speed rotation; the low-speed rotation is used to shake the muddy wastewater, and the high-speed rotation is used to throw away the excess water in the muddy wastewater.

[0074] When controlling the centrifugal filter cartridge 4 of the centrifugal separation component to achieve fixed-axis rotation, a multi-directional drive unit is required to control the corresponding driven gear 6 to rotate. When the driven gear 6 rotates, it can drive the centrifugal filter cartridge 4 to achieve fixed-axis rotation relative to the drainage riser 3 and the multi-purpose component for primary filtration and discharge. When the slow and low-speed rotation is turned on, the water liquid in the centrifugal cavity of the centrifugal filter cartridge 4 can be initially filtered downward. During the initial filtration process, the wastewater is further shaken by slow rotation, so that the water in the wastewater can be better discharged to the multi-purpose component for primary filtration and discharge at the lower part, and finally drained into the interior of the primary filtration water storage tank 2.

[0075] In a normal installation state, since the receiving fixing ring 7 abuts against the top of the primary filter and discharge multi-purpose component, and the centrifugal filter cartridge 4 is sleeved on the upper outer side of the primary filter and discharge multi-purpose component, the centrifugal filter cartridge 4 can maintain its own stability when rotating.

[0076] In summary, it can be seen that the self-cleaning muddy wastewater purification treatment equipment can quickly complete the initial sedimentation and initial filtration of the water in the wastewater when treating the muddy wastewater, thereby realizing the rapid initial sedimentation and collection of the water. After the collection is completed, it can rely on the multi-directional drive unit to synchronously complete the slow drive or high-speed centrifugal drive of multiple centrifugal filter cartridges 4, effectively improving the efficiency of the initial separation of mud and water; when using the centrifugal filter cartridge 4 to treat muddy wastewater, it can regularly realize the rapid cleaning of the sludge adhering to the inner and outer walls of the centrifugal filter cartridge 4, effectively ensuring the use effect of the centrifugal filter cartridge 4 and improving the mud treatment effect in the wastewater; the entire equipment can The wastewater and mud are collected and transported in different directions respectively, which effectively ensures the diversion treatment effect when treating mud-containing wastewater and ensures that the mud and liquid do not mix; the hydraulic self-cleaning component can rely on the water liquid that has been initially filtered to push and pressurize it, and control the water entering the inverted U-shaped tube through a two-way power pump to flow downward along its two vertical sections and rely on water pressure to press downward to push the plunger column to move downward, thereby driving the scraper ring to move downward to scrape the material, completing the control of the reciprocating cleaning treatment of the outer surface of the centrifugal filter cartridge 4, effectively ensuring the smoothness of the outer surface of the centrifugal filter cartridge 4 during long-term wastewater separation treatment, thereby improving the mud and water treatment effect.
