Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage separator and a working method thereof. Background Art

[0002] Water is a non-renewable resource. The rapid development of industry, agriculture, and urbanization in my country in recent years has caused severe environmental pollution, with water pollution being a particularly prominent issue. Despite increasing national investment in environmental protection, the water environment continues to deteriorate, with outdated sewage separation equipment being a key factor.

[0003] The main working modes of existing sewage separation equipment include gravity sedimentation technology that relies on natural sedimentation to separate suspended matter, centrifugal separation technology that uses high-speed rotation to achieve solid-liquid separation, mechanical filtration technology through mechanical extrusion or screen filtration, biodegradation technology that relies on microbial degradation of organic matter, and membrane separation technology. However, they generally have the following disadvantages:

[0004] (1) Current mainstream equipment faces two core constraints in practical applications. The first is its large size. Traditional equipment relies on external high-power motors that occupy a large area. The power unit is mostly equipped with a three-phase asynchronous motor with a power output of more than 30kW, resulting in the weight of the entire machine often exceeding 2 tons. Special flatbed trucks are required for transportation, and the maneuverability is extremely poor in narrow pipelines, river slopes and other scenarios.

[0005] (2) It is difficult to adapt the power supply for field construction. Most dredging scenes are located in areas not covered by the power grid and need to rely on diesel generators for power supply. At the same time, most dredging workers do not have electrician qualifications, and incorrect wiring of high-power equipment can easily cause electric shock and short circuit accidents.

[0006] (3) Sludge with high solid content (>15%) can easily cause equipment blockage. For example, in the wastewater treatment of textile and papermaking industries, the screw conveyor device has a blockage rate of up to 42 times per thousand working hours due to fiber entanglement. A single blockage removal takes 45 minutes, which seriously reduces the treatment efficiency. In addition, most equipment needs to be shut down and manually disassembled and cleaned, and a single maintenance is very time-consuming. Summary of the Invention

[0007] The purpose of the present invention is to provide a sewage separator and a working method thereof, so as to solve the problems of bulky equipment and difficulty in transportation in the prior art.

A plurality of sprockets are axially spaced apart on the driving shaft and the driven shaft, and the sprockets on the driving shaft and the corresponding sprockets on the driven shaft are driven by a chain. A scraper is connected between the outer chain plates of two adjacent groups of the chains. The scraper is used to scrape the filter residue on the upper surface of the coarse filter to the guide plate when the driving shaft is started.

[0027] Fine filtration: The sewage in the water storage component is pumped into the separation component by the water pump component.

[0031] (2) When the sewage separator of the present invention is used to treat sewage, the external sewage falls above the coarse filter through the sewage inlet pipe, and the sewage after coarse filtration through the coarse filter falls into the water storage component for temporary storage; after starting the water pump component, the sewage in the water storage component can be pumped into the separation component for separation, and the sewage separated by the separation component falls above the fine filter through the separation sewage outlet, and the clean water filtered by the fine filter falls on the coarse filter, thereby diluting the impurity concentration in the sewage entering from the sewage inlet pipe, thereby playing a role in preventing blockage; and the clean water separated by the separation component is discharged into the buffer component through the overflow pipe, and can be discharged after sedimentation through the buffer component. It can be seen that the clean water obtained by the above-mentioned fine filtration will fall above the coarse filter, thereby diluting the concentration of impurities in the external sewage, which is beneficial to improving the filtering effect of the coarse filter, greatly alleviating the blockage phenomenon of the coarse filter, reducing the number of cleaning times, and thus improving work efficiency.

DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0043] See also Figure 1 as well as Figure 5 The present application provides a sewage separator, comprising a frame 100 and a water pump assembly 200, a water storage assembly 300, a filter assembly 400, a separation assembly 500 and a buffer assembly 600 arranged on the frame 100; the filter assembly 400 comprises a flow-blocking outer frame 401, a coarse filter 405 and a fine filter 404, the flow-blocking outer frame 401 is arranged at the upper end of the water storage assembly 300, the coarse filter 405 and the fine filter 404 are arranged at intervals from bottom to top inside the flow-blocking outer frame 401; a sewage inlet pipe 406 is provided on the side of the flow-blocking outer frame 401, and the sewage inlet pipe 406 is used for The sewage is introduced above the coarse filter 405; the buffer component 600 is located on one side of the filter component 400, and the buffer component 600 is used to buffer and settle the water discharged into it before discharging it; the separation component 500 is erected above the filter component 400 and the buffer component 600, and the separation water inlet pipe 502 of the separation component 500 is connected with the water storage component 300 through the water pump component 200, and the separation sewage outlet 505 of the separation component 500 is aligned with the top of the fine filter 404, and the overflow pipe 504 of the separation component 500 is connected with the buffer component 600.

[0044] The method for using the above-mentioned sewage separator comprises the following steps:

[0045] Coarse filtration: The sewage passes through the sewage inlet pipe 406 and falls onto the coarse filter 405 for coarse filtration. The sewage after coarse filtration falls into the water storage assembly 300.

[0046] Fine filtration: The sewage in the water storage assembly 300 is pumped into the separation assembly 500 by the water pump assembly 200. The sewage separated by the separation assembly 500 falls on the top of the fine filter 404 through the separation sewage outlet 505. The purified water filtered by the fine filter 404 falls on the coarse filter 405, thereby diluting the impurity concentration in the sewage entering from the sewage inlet pipe 406.

[0047] Sedimentation: The purified water separated by the separation component 500 is discharged into the buffer component 600 through the separation outlet 503 and the overflow pipe 504, and is discharged after sedimentation through the buffer component 600.

[0048] The working principle of the above-mentioned sewage separator is as follows: when the sewage separator of the present invention is used to treat sewage, the external sewage falls above the coarse filter 405 through the sewage inlet pipe 406, and the sewage after coarse filtration through the coarse filter 405 falls into the water storage component 300 for temporary storage; after starting the water pump component 200, the sewage in the water storage component 300 can be pumped into the separation component 500 for separation, and the sewage separated by the separation component 500 falls above the fine filter 404 through the separation sewage outlet 505, and the clean water filtered by the fine filter 404 falls on the coarse filter 405, thereby diluting the impurity concentration in the sewage entering from the sewage inlet pipe 406, thereby playing a role in preventing blockage; and the clean water separated by the separation component 500 is discharged into the buffer component 600 through the overflow pipe 504, and can be discharged after sedimentation through the buffer component 600.

[0049] Traditional sewage filtration methods are usually step-by-step filtration, that is, sewage is sequentially filtered through coarse filtration and fine filtration before being discharged. This method can cause the coarse filter 405 to become clogged in a relatively short period of time when processing sewage with a high solid impurity content, requiring frequent cleaning of filtered impurities, greatly reducing work efficiency. In contrast, the present application arranges the fine filter 404 above the coarse filter 405 so that the purified water obtained through fine filtration falls above the coarse filter 405, thereby mixing with the external sewage for coarse filtration. This is equivalent to diluting the impurity concentration in the external sewage, thereby improving the filtration effect of the coarse filter 405, greatly alleviating the clogging phenomenon of the coarse filter 405, reducing the number of cleanings, and thus improving work efficiency.

[0050] This application does not limit the specific structure of the separation component 500. Figure 5 As shown, the vortex separator 501 is preferably used. The vortex separator 501 has a separation water inlet pipe 502, a separation water outlet 503 and a separation sewage outlet 505. The specific structure and working principle of the vortex separator 501 are both existing technologies and will not be described in detail here.

[0051] See for example Figures 5 to 8As shown, in order to further improve the anti-blocking effect of the coarse filter 405, the coarse filter 405 is a plate-shaped structure; a guide plate 402 is provided on the side of the baffle frame 401 away from the buffer assembly 600, and the guide plate 402 is arranged downwardly in a direction away from the baffle frame 401; the sewage separator also includes a cleaning assembly 700, and the cleaning assembly 700 includes a driving shaft 703 and a driven shaft 704, and the driving shaft 703 and the driven shaft 704 are both rotatably arranged at The baffle outer frame 401, the driving shaft 703 and the driven shaft 704 are both provided with a plurality of sprockets 705 spaced apart along the axial direction, and the sprockets 705 on the driving shaft 703 and the corresponding sprockets 705 on the driven shaft 704 are driven by a chain 706, and a scraper 707 is connected between the outer chain plates 7061 of two adjacent groups of the chains 706, and the scraper 707 is used to scrape the filter residue on the upper surface of the coarse filter 405 to the guide plate 402 when the driving shaft 703 is started. When the driving shaft 703 is started, the sprocket 705 on the driving shaft 703 will drive the chain 706 to rotate, and the chain 706 will drive the hanging bar to scrape the upper surface of the coarse filter 405, thereby pushing the filter residue to the guide plate 402 for discharge, thereby reducing the accumulation of filter residue on the upper surface of the coarse filter 405, improving its anti-blocking effect, and reducing the number of manual cleaning times. In addition, if Figure 8 As shown, since the angle between the outer link plate 7061 and the inner link plate 7062 of the chain 706 will change when the chain 706 passes the position of the sprocket 705, the scraper 707 is set between the corresponding outer link plates 7061 on two adjacent chains 706 to prevent interference during operation.

[0052] The reason for setting the cleaning assembly 700 above the coarse filter 405 is that when the coarse filter 405 filters sewage with a high solid impurity content, the coarse filter 405 will filter out most of the impurities, which makes the coarse filter 405 prone to clogging. Therefore, an active cleaning method is added above the filter to actively remove the filter residue remaining above the coarse filter 405, thereby reducing the number of manual cleaning times. The cleaning assembly 700 is not set above the fine filter 404 because after filtering through the coarse filter 405, the large particles of impurities in the sewage have been filtered out. After reaching the fine filter 404, the small particles of impurities in the sewage are filtered out. The effect of scraping such small particles with a hanging bar is limited, so the cleaning assembly 700 is not set above the fine filter 404. The manual cleaning method is prior art, such as disassembling the coarse filter 405 and the fine filter 404 for backwashing. At this time, the coarse filter 405 and the fine filter 404 need to be fixed in a detachable manner. The specific detachable method is also prior art and will not be described in detail here.

[0053] See Figure 5As shown, to reduce the amount of sewage on the coarse filter 405 that is discharged through the guide plate 402, the coarse filter 405 is arranged to be tilted downward in the direction of the buffer assembly 600. Similarly, the fine filter 404 can also adopt a similar structural arrangement. At the same time, to improve the mixing effect between the purified water from the fine filtration and the sewage entering from the outside, the separation sewage outlet 505 of the separation assembly 500 is aligned with the lower end of the fine filter 404, and the sewage inlet pipe 406 is aligned with the lower end of the coarse filter 405. At the same time, a flow shield 506 can also be provided on the outside of the separation sewage outlet 505. The flow shield 506 can reduce the impact of the water flow on the fine filter 404 on the one hand, and can also change the direction of the water flow, so that the water entering the fine filter 404 through the separation sewage outlet 505 is closer to the sewage in the sewage inlet pipe 406 after fine filtration, thereby improving the mixing effect.

[0054] See Figure 8 As shown, the hanging bar includes a fixing portion 7071 and multiple fins 7072. The fixing portion 7071 is connected to two corresponding outer link plates 7061 at each end. The fins 7072 are integrally formed with the fixing portion 7071, with gaps between adjacent fins 7072. The fixing portion 7071 facilitates securement to the outer link plates 7061, either by gluing or by screws thinner than the outer link plates 7061. The multiple fins 7072 are integrally formed for ease of processing, and the gaps between them enhance their flexibility and prevent damage to the filter screen.

[0055] See Figure 5 As shown, the buffer assembly 600 includes a buffer box 601. The top of the buffer box 601 is connected to the overflow pipe 504, and the bottom of the buffer box 601 is provided with a drain port 604. The cleaning assembly 700 also includes an impeller 701 and a transmission member 702. The impeller 701 is rotatably mounted on the buffer box 601, and the water flow entering the buffer box 601 from the overflow pipe 504 is used to drive the impeller 701 to rotate. The impeller 701 is connected to the driving shaft 703 via the transmission member 702. Since the driving shaft 703 requires power input, external power input will increase energy consumption, and the water flow entering the buffer box 601 from the overflow pipe 504 is relatively high, which will cause the sedimentation effect in the buffer box 601 to decrease. Therefore, an impeller 701 is added to the buffer box 601, and the water flow entering the buffer box 601 is used to drive the impeller 701 to rotate, thereby driving the driving shaft 703 to rotate through the transmission member 702. This can reduce the speed of the water flow entering the buffer box 601, thereby reducing the impact on the sedimentation effect; at the same time, it also provides power for the driving shaft 703, reducing energy consumption.

[0056] See Figure 9As shown, in order to further reduce the influence of water flow on the sedimentation effect, a first baffle 602 and a second baffle 603 are provided in the buffer box 601; the first baffle 602 includes a first vertical section, a connecting section and a second vertical section, the first vertical section is located on the side of the impeller 701 away from the overflow pipe 504, the upper end of the first vertical section is higher than the impeller 701, the lower end of the first vertical section is connected to the second vertical section through the connecting section, the second vertical section is located on the lower side of the impeller 701, and a gap is left between the lower end of the second connecting section and the buffer box 601, and the connecting section is arranged to be inclined downward in the direction of the second vertical section; the second baffle 603 is vertically arranged between the drain outlet 604 and the second vertical section, the lower end of the second baffle 603 is connected to the bottom of the buffer box 601, and a gap is left between the upper end of the second baffle 603 and the connecting section. After the water flows into the impeller 701 through the overflow pipe 504, it falls to the bottom of the buffer tank 601 along the connecting section and the second vertical section in turn. The inclined arrangement of the connecting section can reduce the amount of impurities remaining on the connecting section; the water that falls to the bottom of the buffer tank 601 overflows through the gap between the connecting section and the upper end of the second partition 603, and is finally discharged from the drain outlet 604.

[0057] The bottom of the buffer box 601 is provided with an openable and closable slag discharge port 605 in an area corresponding to the second vertical section. Opening the slag discharge port 605 facilitates regular cleaning of impurities remaining at the bottom of the buffer box 601. The slag discharge port 605 can be opened and closed using conventional methods, such as a flange fixed by bolts. Cleaning can be performed by removing the bolts and the flange.

[0058] See Figure 2 As shown, to address the problem in existing technology of relying on high-power motors, requiring an external power source and easily posing electrical safety risks, the water pump assembly 200 includes a pump body 203 and a hydraulic motor 204. Both the pump body 203 and the hydraulic motor 204 are mounted on the frame 100, with the hydraulic motor 204 providing power to the pump body 203. The pump body 203 is provided with a water pump inlet 201 for connecting to the water storage assembly 300 and a water pump outlet 202 for connecting to the separation water inlet pipe 502. By using the hydraulic motor 204 instead of an electric motor, power transmission relies on an oil circuit, whereas electric motors rely on cables, completely eliminating the risk of electric shock during field operations and improving safety.

[0059] See Figure 3 and Figure 4 As shown, the water storage assembly 300 includes a water storage tank 301, which is arranged on the frame 100, and the top of the water storage tank 301 is connected to the flow blocking frame 401 (as shown in FIG. Figure 5The water tank 301 is docked with the guide plate 402. A guide plate 302 is provided on one side of the water tank 301 corresponding to the guide plate 402. One end of the guide plate 302 is hinged to the frame 100. The guide plate 302 is supported by a support rod 303, and the support rod 303 is hinged to the guide plate 302. When the end of the support rod 303 away from the guide plate 302 is supported on the frame 100, the guide plate 302 can be tilted outward, thereby discharging the filter residue guided by the guide plate 402 to a position away from the frame 100. A water storage outlet pipe 306 for connecting to the water pump assembly 200 is provided on the side of the water tank 301. In order to solve the problem of excessive accumulation of impurities at the bottom of the water tank 301 after long-term use, a water inlet pipe 304 is further provided on the side of the water tank 301, and a regulating valve 305 is provided on the water inlet pipe 304. When the water inlet pipe 304 is connected to an external clean water source (the water source can be the clean water discharged by the buffer component 600), the regulating valve 305 is opened to flush the bottom of the water tank 301.

[0060] See Figure 1 and Figure 5 As shown, to enhance filtration efficiency, the filter assembly 400 further includes a vibration generator 403, which is mounted on the side of the flow-blocking outer frame 401. This vibration during filtration enhances filtration efficiency. To protect the entire apparatus from being affected by the vibration generator 403, the flow-blocking outer frame 401 is connected to the frame 100 via a shock absorber 101. Shock absorber 101 itself is conventional technology and will not be described in detail here.
