Description

Technical Field

[0001] The present invention relates to the field of environmental protection treatment equipment, and particularly relates to a sewage filtration processor and a separation method thereof. Background Art

[0002] Dusty sewage refers to sewage containing a certain amount of solid particles, which mainly includes atmospheric dust, industrial dust, water sediment, and other harmful solid substances. This type of sewage is usually generated during industrial production processes, such as in industries like mining, ore dressing, building materials, and chemical engineering. Dusty sewage may cause environmental pollution and needs to be treated through appropriate treatment methods to meet environmental protection requirements and the purpose of water resource recycling. To separate the solid substances in the sewage for sewage treatment, a filter is usually used as the separation device. The separated sludge has a soft volume and a large water content, and needs to be subsequently extruded to form a filter cake, with complex processes. In addition, current sewage filtration machinery cannot accurately control the volume of the filter cake, which is not conducive to the subsequent harmless and resource utilization of the filter cake, and is prone to clogging the filter screen serving as the filtration structure, requiring regular manual cleaning or replacement of the filter screen. The filtration action relies only on the self-weight of the water liquid to separate the solid waste, resulting in a slow separation speed and low treatment efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a sewage filtration processor and a separation method thereof to solve the above problems. By arranging a spiral sheet that fits the inner wall of the separation tank inside the separation tank, the wastewater input into the separation tank along the waste supply pipe is first filtered by the spiral sheet in a rotating state. The solid waste that cannot pass through the spiral sheet is transported upward to the top cover and output upward, achieving solid-liquid separation. The solid waste is secondarily filtered by two groups of filter sheets. The rotation action of the spiral sheet cooperates with a scraper to shovel the solid waste upward and transport it upward, improving the smoothness of the filter sheet and the cleanliness of the waste removal. Details are described below.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0009] Preferably, the flow splitting assembly includes a left storage tank and a right storage tank distributed corresponding to the left filter plate and the right filter plate and vertically corresponding and communicating. Two groups of partition plates are horizontally and parallelly distributed inside the pump tank. The opposite sides of the two groups of partition plates and the inner wall of the pump tank form a left chamber and a right chamber. Vertical communication pipes connecting the pump tank are arranged at the bottom sides of the left storage tank and the right storage tank.

[0010] Preferably, two vertically extending drain pipes are connected to the bottom of the pump tank corresponding to the left chamber and the right chamber. A crank is rotatably arranged in the middle of the pump tank. The top end of the crank is fixed with a lower transmission disc drivingly connected to the upper transmission disc. The partition plates are horizontally slidably sealed with the inner wall of the pump tank. Traction arms are hinged to the opposite sides of the two groups of partition plates. The end of the traction arm far from the partition plate is hinged to the crank.

[0011] Preferably, check valves are arranged in the middle of the communication pipes and the drain pipes. A side cover is arranged at the front opening of the pump tank. A guide rod for supporting the horizontal sliding of the partition plates is horizontally fixed in the middle of the pump tank. Installation ears extending longitudinally are fixed to the front and rear sides of the separation tank. A tank body column vertically extending to support the separation tank is fixed to the bottom side of the installation ear.

[0012] Preferably, an orbital ring is arranged above the top cover. A synchronous ring is coaxially arranged on the top side of the orbital ring. A plurality of movable cylinders are arranged around the top side of the synchronous ring. A cage is connected between the plurality of movable cylinders. A vertically extending side column is fixed to the bottom side of the orbital ring. A reinforcing beam is connected between the side column and the tank body column.

[0013] Preferably, a constraint groove for accommodating the rotation of the synchronous ring is arranged on the top side of the orbital ring. A feeding hole communicating with the fixed pipe is vertically penetrated through the constraint groove. A discharging hole is vertically penetrated through the constraint groove in front of the feeding hole. A frame is fixed to the inner side of the orbital ring. A motor for supporting the rotation of the cage is fixed in the middle of the frame.

[0014] Preferably, a plurality of auxiliary holes vertically penetrating through the bottom side of the synchronous ring and communicating with the movable cylinder are provided. A pressing plate is vertically slidably arranged inside the movable cylinder. A supporting rod vertically passing through the movable cylinder is fixed to the top side of the pressing plate. A limiting block is fixed to the top end of the supporting rod. A spring for pressing the pressing plate downward is sleeved outside the bottom end of the supporting rod. A plurality of induction rings sleeved outside the movable cylinder are fixed to the outer side of the retaining frame. The induction rings are used to detect the height position of the pressing plate.

[0015] The separation method of the sewage filtration processor includes the following steps:

[0016] a. Sewage containing impurities to be separated into solid and liquid is input into the separation tank along the waste supply pipe. The main shaft supporting the spiral blade is driven by a driving member to rotate. The filter holes on the spiral blade are used to guide the water liquid downward, and the intercepted solid waste is pushed upward by the rotating spiral blade to achieve solid-liquid separation.

[0017] b. The waste accumulated on the top side of the filter disc along with the water flow is shoveled and scraped upward by the scraper rotating with the spiral blade. When the scraper rotates to one side of the left filter blade, the main shaft drives the crank to rotate towards the side close to the left cavity. The two partition plates are driven to move horizontally by the crank. The left cavity is compressed and the right cavity is stretched. At this time, the right cavity sucks the water liquid at the position of the right filter blade through the connecting pipe and the right storage tank, that is, the liquid and solid waste at the top side of the filter disc are attracted to flow towards the position of the right filter blade, so as to assist the scraper in removing the waste on the top side of the left filter blade.

[0018] c. When the scraper rotates to the position of the left filter blade, the crank pushes the partition plate to compress the left cavity, so that the water liquid in the left cavity is discharged along the lower drain pipe. In addition, the downward suction force at the position of the left filter blade is released, ensuring that the scraper can alternately control the suction and drainage states of the two filter blades when rotating and moving between the left filter blade and the right filter blade.

[0019] d. The solid waste conveyed into the top cover by the rotation of the spiral blade enters the fixed pipe under the compression of the conical top cover, is extruded into a cylindrical shape and conveyed upward. The columnar waste enters the movable cylinder successively along the fixed pipe, the feeding hole and the auxiliary hole. The movable cylinder serves as a storage container for the waste, and the solid waste is secondarily compressed and compacted by the pressing plate pushed and pressed by the spring inside the movable cylinder.

[0020] e. When the solid waste in the movable cylinder communicating with the feeding hole continuously conveys upward to push the pressing plate to move up to the position of the induction ring, the induction ring detects that the storage amount of the solid waste in the movable cylinder reaches the set requirement. The motor drives the retaining frame to drive the plurality of movable cylinders and the synchronous ring to rotate as a whole. The movable cylinder storing the solid waste rotates to the position of the discharging hole along the feeding hole position, and the spring is used to push the pressing plate downward to discharge the solid waste along the discharging hole.

[0021] The beneficial effects are as follows: 1. In the present invention, spiral sheets are arranged inside the separation tank to fit the inner wall of the tank body, and filter holes are densely distributed on the spiral sheets as the primary filtration structure. The wastewater input into the separation tank along the waste supply pipe is first filtered by the spiral sheets in a rotating state. The liquid that can pass through the filter holes continuously flows downward, and the solid waste that cannot pass through the spiral sheets is transported upward to the top cover and output upward, realizing solid-liquid separation;

[0022] 2. The filter disc at the drainage outlet position at the bottom of the separation tank serves as the secondary filtration structure. The solid waste that follows the liquid flow to the top side of the filter disc is secondarily filtered by two groups of filter sheets. The filter sheets intercept the solid waste in the liquid on the top side of the filter disc, and the rotating action of the spiral sheets cooperates with the scraper to shovel up the solid waste upward and transport it upward;

[0023] 3. During the rotation of the scraper, the rotation position of the scraper is consistent with the rotation position of the lower crank, realizing the contraction and expansion of the left and right chambers in the pump box, so as to alternately perform the suction and drainage actions of the two groups of filter sheets, thereby ensuring that the scraper can smoothly cut off the solid waste at the corresponding position, avoiding partial impurities being sucked into the sieve holes of the filter sheets due to the downward drainage suction, and improving the smoothness of the filter sheets and the cleanliness of the waste removal;

[0024] 4. In addition, a plurality of rotatable movable cylinders are arranged above the fixed pipe serving as the discharge channel for solid waste. The movable cylinders are used as the quantitative containment containers for solid waste, and the compacted solid waste is quantitatively discharged by the rotation of the plurality of movable cylinders, facilitating subsequent harmless and resource utilization according to the compressed and quantitatively formed columnar solid waste, and being more convenient to use.

[0039] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0040] Refer to Figures 1 - 11As shown in the figure, the present invention provides a sewage filtration processor, which includes a separation tank 1 and a top cover 2. The separation tank 1 is a vertically penetrating hollow structure. The top cover 2 is arranged at the top opening of the separation tank 1. A flow splitting component 3 is arranged at the bottom of the separation tank 1, and a pump box 4 is arranged below the flow splitting component 3. The separation tank 1 serves as a sewage solid-liquid separation container;

[0041] A main shaft 101 extending vertically is rotatably arranged in the middle of the separation tank 1. A waste supply pipe 102 extending outward is connected to the middle of the separation tank 1. The external sewage is supplied and input into the separation tank 1 through the waste supply pipe 102. A spiral sheet 103 that fits the inner wall of the separation tank 1 and extends spirally is fixed outside the main shaft 101. The surface of the spiral sheet 103 is densely distributed with vertically penetrating filter holes 103a, so as to use the spiral sheet 103 in a rotating state as a pushing structure for upward output of solid waste. The bottom end of the main shaft 101 penetrates downward through the flow splitting component 3 and extends above the pump box 4. A driving member (not shown in the figure) for supporting the rotation of the main shaft 101 is fixed on the top side of the pump box 4. The driving member is a servo motor 505.

[0042] As an optional implementation manner, a disc-shaped filter disc 106 is arranged at the bottom opening of the separation tank 1. A left filter sheet 106a and a right filter sheet 106b with a semi-circular porous structure are symmetrically arranged horizontally in the middle of the filter disc 106. A rotating sleeve 106c for vertically penetrating the main shaft 101 is vertically penetrated through the center of the filter disc 106. A sealing bearing for supporting the rotation of the main shaft 101 is arranged in the middle of the rotating sleeve 106c. A scraper 103b flush with the top surface of the filter disc 106 is fixed on the bottom side edge of the spiral sheet 103. The scraper 103b rotates with the spiral sheet 103 to shovel up and convey upward the solid waste accumulated and adsorbed on the top side of the filter disc 106. An upper transmission disc 105 is fixed at the bottom end of the main shaft 101. The top cover 2 is a conical cylinder structure with a gradually shrinking top. A cylindrical fixing pipe 201 is vertically penetrated through the top of the top cover 2. The top cover 2 compresses the solid waste into a column shape and conveys it upward along the fixing pipe 201 for discharge. A shaft frame 202 for supporting the rotation of the main shaft 101 and the spiral sheet 103 is horizontally arranged inside the top cover 2. The width of the shaft frame 202 is smaller than the inner diameter of the fixing pipe 201 to prevent the shaft frame 202 from obstructing the upward conveying channel of the solid waste. The flow splitting component 3 includes a left storage tank 301 and a right storage tank 302 that are distributed corresponding to the left filter sheet 106a and the right filter sheet 106b and are vertically and correspondingly connected. The opposite sides of the left storage tank 301 and the right storage tank 302 are not connected. Two groups of partition plates 402 are horizontally and parallelly distributed inside the pump box 4. The opposite sides of the two groups of partition plates 402 and the inner wall of the pump box 4 form a left cavity 403 and a right cavity 404 with variable volumes. Vertical connecting pipes 303 communicating with the pump box 4 are arranged at the bottom sides of the left storage tank 301 and the right storage tank 302. The left cavity 403 is connected to the left storage tank 301 through the upper connecting pipe 303, and the right cavity 404 is connected to the right storage tank 302 through another upper connecting pipe 303;

[0043] At the bottom of the pump box 4, there are two vertically extending drain pipes 406 communicating with the left chamber 403 and the right chamber 404 correspondingly. A crank 408 is rotatably arranged in the middle of the pump box 4. At the top end of the crank 408, a lower driving disk 407 is fixedly arranged and drivingly connected to the upper driving disk 105 to ensure that the crank 408 rotates synchronously with the main shaft 101. The partition 402 is horizontally slidably sealed with the inner wall of the pump box 4. Traction arms 409 are hinged on the opposite sides of the two groups of partitions 402. One end of the traction arm 409 far from the partition 402 is hinged to the crank 408 to ensure that the crank 408 can drive the traction arm 409 to support the two groups of partitions 402 to slide horizontally, thereby changing the volume sizes of the left chamber 403 and the right chamber 404. Check valves are arranged in the middle of the connecting pipe 303 and the drain pipe 406. The check valves on the connecting pipe 303 and the drain pipe 406 restrict the water liquid to only flow downward. A side cover 401 is arranged at the front opening of the pump box 4, and a guide rod 405 for horizontally supporting the sliding of the partition 402 is horizontally fixed in the middle of the pump box 4 to improve the stability of the partition 402 sliding horizontally in the pump box 4. Installation ears 104 extending longitudinally are fixedly arranged on the front and rear sides of the separation tank 1. A tank body column 10 extending vertically to support the separation tank 1 is fixedly arranged at the bottom side of the installation ear 104;

[0044] Above the top cover 2, there is an orbital ring 5. A synchronous ring 6 is coaxially arranged on the top side of the orbital ring 5. A plurality of movable cylinders 8 serving as solid waste storage containers are arranged around the top side of the synchronous ring 6. A cage 7 is connected between the plurality of movable cylinders 8 to ensure that the synchronous ring 6, the movable cylinders 8 and the cage 7 can maintain an integral state. A side column 11 extending vertically is fixedly arranged at the bottom side of the orbital ring 5. A reinforcing beam 12 is connected between the side column 11 and the tank body column 10. The distance between the lower part of the reinforcing beam 12 and the bottom end of the side column 11 is not less than 2 meters, leaving a passage for personnel to walk;

[0045] A constraint groove 501 for accommodating the rotation of the synchronous ring 6 is arranged on the top side of the orbital ring 5. A feeding hole 502 communicating with the fixed pipe 201 vertically penetrates through the constraint groove 501. A discharging hole 503 vertically penetrates through the constraint groove 501 in front of the feeding hole 502. A frame 504 is fixedly arranged inside the orbital ring 5. A motor 505 for supporting the rotation of the cage 7 is fixedly arranged in the middle of the frame 504. A plurality of auxiliary holes 601 communicating with the movable cylinders 8 vertically penetrate through the bottom side of the synchronous ring 6 to ensure that the movable cylinders 8 can be kept in communication with the fixed pipe 201 through the auxiliary holes 601 and the feeding hole 502, so that solid waste can be input upward into the movable cylinders 8 for compression and quantitative forming. A hopper 9 is arranged below the orbital ring 5 corresponding to the discharging hole 503. A supporting lifting ear 901 fixedly connected to the orbital ring 5 is arranged on the top side of the hopper 9 to receive the solid waste in the shape of a columnar compressed body discharged downward along the discharging hole 503;

[0046] A pressing plate 802 is vertically slidably arranged inside the movable cylinder 8. A support rod 801 vertically passing through the movable cylinder 8 is fixed to the top side of the pressing plate 802. A limit block 803 is fixed to the top end of the support rod 801. A spring 804 for pressing the pressing plate 802 downward is sleeved outside the bottom end of the support rod 801. Multiple induction rings 701 sleeved outside the movable cylinder 8 are fixed to the outside of the cage 7. The induction rings 701 are used to detect the height position of the pressing plate 802. The induction rings 701 are capacitive induction switches for detecting the upward movement position of the pressing plate 802, so as to quantitatively collect the solid waste in the movable cylinder 8, which is convenient for subsequent treatment according to the quantitative columnar solid waste. Specifically, during harmless treatment, the solid waste discharged from one movable cylinder 8 is taken as one section, and the dosage of the medicament required for resource treatment is set according to the weight of one section of solid waste, so as to conveniently select the required dosage of the medicament according to the number of sections of the solid waste; or during resource treatment, according to the number of sections of the solid waste to be treated, the size of the composting site meeting the requirements is correspondingly set to facilitate subsequent treatment after quantifying the solid waste;

[0047] The separation method of the sewage filtration processor includes the following steps:

[0048] a. Sewage containing impurities to be separated into solid and liquid is input into the separation tank 1 along the waste supply pipe 102. The main shaft 101 drives the support spiral blade 103 to rotate through the driving member. The filter holes 103a on the spiral blade 103 are used to guide the water liquid downward, and the intercepted solid waste is pushed upward by the rotating spiral blade 103 to realize solid-liquid separation;

[0049] b. The waste accumulated on the top side of the filter disc 106 along with the water flow is shoveled and scraped upward by the scraper 103b rotating with the spiral blade 103. When the scraper 103b rotates to the side of the left filter piece 106a, the main shaft 101 drives the crank 408 to rotate towards the side close to the left cavity 403. The two partition plates 402 are driven to move horizontally by the crank 408. The left cavity 403 is compressed, and the right cavity 404 is stretched. At this time, the right cavity 404 sucks the water liquid at the position of the right filter piece 106b downward through the communication pipe 303 and the right storage tank 302, that is, attracts the liquid and solid waste at the top side position of the filter disc 106 to flow towards the position of the right filter piece 106b, so as to assist the scraper 103b in removing the waste on the top side of the left filter piece 106a;

[0050] c. When the scraper 103b rotates to the position of the left filter piece 106a, the crank 408 pushes the partition plate 402 to compress the left cavity 403, so as to discharge the water liquid in the left cavity 403 along the lower drain pipe 406. In addition, the downward suction force at the position of the left filter piece 106a is released, ensuring that the scraper 103b can alternately control the suction and drainage states of the two filter pieces when rotating and moving between the left filter piece 106a and the right filter piece 106b;

[0051] d. The solid waste transported by the spiral blade 103 into the interior of the top cover 2 is compressed by the conical top cover 2. The solid waste enters the fixed pipe 201, is extruded into a cylindrical shape and conveyed upward. The columnar waste successively enters the movable cylinder 8 along the fixed pipe 201, the feeding hole 502 and the auxiliary hole 601. The movable cylinder 8 serves as a storage container for the waste. The pressing plate 802 pushed and pressed by the spring 804 in the movable cylinder 8 performs secondary compression and compaction on the solid waste.

[0052] e. When the solid waste in the movable cylinder 8 at the position communicating with the feeding hole 502 continues to be conveyed upward to push the pressing plate 802 upward to the position of the induction ring 701, and the induction ring 701 detects that the storage amount of the solid waste in the movable cylinder 8 reaches the set requirement, the motor 505 is used to drive the cage 7 as a whole to drive multiple groups of movable cylinders 8 and the synchronous ring 6 to rotate. The movable cylinder 8 storing the solid waste rotates along the position of the feeding hole 502 to the position of the discharging hole 503, and the spring 804 is used to push the pressing plate 802 downward to discharge the solid waste along the discharging hole 503.

[0053] In the present invention, a spiral blade 103 fitting the inner wall of the separation tank 1 is arranged inside the separation tank 1. Filter holes 103a are densely distributed on the spiral blade 103 as a primary filtering structure. The wastewater input into the separation tank 1 along the waste supply pipe 102 is first filtered by the spiral blade 103 in a rotating state. The water liquid that can pass through the filter holes 103a continuously flows downward, and the solid waste that cannot pass through the spiral blade 103 is conveyed upward to the top cover 2 and output upward, realizing solid-liquid separation.

[0054] The filter disc 106 at the bottom drainage port position of the separation tank 1 serves as a secondary filtering structure. The solid waste following the water liquid flowing to the top side of the filter disc 106 is secondarily filtered by two groups of filter sheets. The filter sheets intercept the solid waste in the water liquid on the top side of the filter disc 106, and the solid waste is shoveled up and conveyed upward by the rotation action of the spiral blade 103 in cooperation with the scraper 103b.

[0055] During the rotation of the scraper 103b, the rotation position of the scraper 103b is consistent with the rotation position of the lower crank 408, realizing the contraction and expansion of the left chamber 403 and the right chamber 404 in the pump box 4 to alternately perform the suction and drainage actions of the two groups of filter sheets, thereby ensuring that the scraper 103b can smoothly cut off the solid waste at the corresponding position, avoiding partial impurities being sucked into the sieve holes of the filter sheets due to the downward drainage suction, and improving the smoothness of the filter sheets and the cleanliness state of the waste removal.

[0056] In addition, multiple groups of rotatable movable cylinders 8 are arranged above the fixed pipe 201 serving as the discharge channel for the solid waste. The movable cylinders 8 are used as quantitative accommodation containers for the solid waste. The compacted solid waste is quantitatively discharged by the rotation of the multiple groups of movable cylinders 8, which is convenient for subsequent harmless and resource utilization according to the quantitatively compressed columnar solid waste, and is more convenient to use.

[0057] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claimed rights.

10. The separation method of the sewage filtration processor according to claim 9, characterized in that: The following steps are involved: a. Sewage containing impurities to be separated into solid and liquid is fed into the separation tank (1) along the waste supply pipe (102), and the main shaft (101) is driven by a driving member to support the spiral blade (103) to rotate, and the filter holes (103a) on the spiral blade (103) are used to guide the water to be transported downward, and the retained solid waste is pushed upward by the rotating spiral blade (103), thereby achieving solid-liquid separation; b. The waste material that is gathered on the top side of the filter disc (106) with the water flowing downward is scraped upward by the scraper (103b) that rotates with the spiral plate (103). When the scraper (103b) rotates to the side of the left filter disc (106a), the main shaft (101) drives the crank (408) to rotate toward the side close to the left chamber (403). The crank (408) drives the two sets of partitions (402) to move horizontally, so that the left chamber (403) is compressed and the right chamber (404) is stretched. At this time, the right chamber (404) sucks the water at the position of the right filter disc (106b) downward through the connecting pipe (303) and the right storage tank (302), that is, the liquid and solid waste at the top side of the filter disc (106) are attracted to flow toward the position of the right filter disc (106b), thereby assisting the scraper (103b) to scrape away the waste material at the top side of the left filter disc (106a); c. When the scraper (103b) rotates to the position of the left filter disc (106a), the crank (408) pushes the partition (402) to compress the left chamber (403), thereby discharging the water in the left chamber (403) along the lower drainage pipe (406). In addition, the downward suction force at the position of the left filter disc (106a) is released, ensuring that the scraper (103b) can alternately control the suction and drainage states of the two groups of filter discs when rotating and moving between the left filter disc (106a) and the right filter disc (106b); d. The solid waste that is rotated and transported to the interior of the top cover (2) by the spiral blade (103) is compressed by the conical top cover (2), and the solid waste enters the fixed tube (201), is squeezed into a cylindrical shape, and is transported upward. The columnar waste enters the movable cylinder (8) along the fixed tube (201), the feeding hole (502), and the auxiliary hole (601) in sequence. The movable cylinder (8) serves as a storage container for the waste, and the solid waste is compressed and compacted for a second time by a pressure plate (802) in the movable cylinder (8) that is pushed and pressed by a spring (804); e. When the solid waste in the movable cylinder (8) connected to the position of the feeding hole (502) is continuously transported upward to push the pressure plate (802) upward to the position of the induction ring (701), the induction ring (701) detects that the storage amount of solid waste in the movable cylinder (8) reaches the set requirement, and the motor (505) drives the retaining frame (7) as a whole to drive the multiple groups of movable cylinders (8) and the synchronous ring (6) to rotate, and the movable cylinder (8) storing the solid waste rotates along the position of the feeding hole (502) to the position of the discharge hole (503), and the spring (804) is used to push the pressure plate (802) downward to discharge the solid waste along the discharge hole (503).
