Description

Technical Field

[0001] The invention relates to the technical field of water treatment, in particular to a segmented wastewater treatment device for oatmeal production. Background Art

[0002] The production process of oatmeal requires operations such as cleaning, crushing and cooking. During these operations, a large amount of wastewater will be generated. The wastewater contains a large amount of suspended matter such as oat husks, impurities such as oat particles, and organic matter such as starch. These different impurities need to be graded and treated.

[0003] In traditional graded treatment, wastewater contains a large amount of suspended matter such as oat husks. If the suspended matter in the wastewater is not removed cleanly, it will block the flocculant from entering the wastewater, affecting the full reaction between the flocculant and the wastewater. When using flocculants to remove starch in the wastewater, the starch flocs produced by the flocculation reaction are sticky and tough. The flocs stick to each other or to the suspended matter, causing the flocs to clump together. The clumped flocs will wrap part of the flocculant in them, causing the flocculant to be unable to fully react with the wastewater, thereby affecting the efficiency of the flocculation reaction.

[0004] Therefore, it is urgent to develop a segmented wastewater treatment device for oatmeal production. Summary of the invention

The inner tank 105 is slidably connected to the first filter plate 106 that cooperates with the rotating shaft 103. The rotating shaft 103 is fixedly connected to a limiting card block. The first filter plate 106 is provided with a limiting card slot. When the limiting card block of the rotating shaft 103 rotates to the limit position of the limiting card slot of the first filter plate 106, the limiting card block of the rotating shaft 103 and the limiting card slot of the first filter plate 106 are locked, so that the rotating shaft 103 drives the first filter plate 106 to rotate through its limiting card block. The first filter plate 106 is provided with a plurality of large-aperture filter holes for filtering suspended matter such as oat husks. The rotating shaft 103 is fixedly connected to the first filter plate 106. The second filter plate 107 is matched, and the second filter plate 107 is provided with a plurality of large-aperture filter holes and a plurality of small-aperture filter holes that are staggered. When the plurality of large-aperture filter holes of the first filter plate 106 are respectively aligned with the plurality of large-aperture filter holes of the second filter plate 107, suspended matter such as oat husks can pass through the large-aperture filter holes of the first filter plate 106 and the second filter plate 107. When the first filter plate 106 is rotated so that its plurality of large-aperture filter holes are respectively aligned with the plurality of small-aperture filter holes of the second filter plate 107, suspended matter such as oat husks cannot pass through the filter holes of the first filter plate 106 and the second filter plate 107. The inner tank 105 is slidably connected to a third filter 106 that is limitedly slidable with the rotating shaft 103. Plate 108, the third filter plate 108 is provided with a plurality of filter holes, the third filter plate 108 is fixedly connected to a limiting block, the rotating shaft 103 is provided with a limiting groove, when the rotating shaft 103 rotates, the third filter plate 108 is driven to rotate through its limiting groove and the limiting block of the third filter plate 108, when the inner tank 105 moves downward, the third filter plate 108 is acted upon by gravity so that its limiting block moves downward along the limiting groove of the rotating shaft 103, when the inner tank 105 moves upward, the limiting block of the third filter plate 108 is driven to move upward along the limiting groove of the rotating shaft 103, the inner tank 105 cooperates with the third filter plate 108 through the filter holes, the filter holes of the inner tank 105 and the filter holes of the third filter plate 108 are both small-aperture filter holes for filtering particulate impurities in wastewater,When the rotating shaft 103 drives the third filter plate 108 to rotate, the filter holes of the inner tank 105 are intermittently aligned with the filter holes of the third filter plate 108 for circulation, and four wastewater channels 109 are evenly distributed circumferentially at a position near the third filter plate 108 inside the shell 101, and a reaction chamber 110 connected to the wastewater channel 109 is provided on the lower side of the shell 101, and the rotating shaft 103 is fixedly connected to a liquid inlet plate 111 located in the reaction chamber 110, and the liquid inlet plate 111 is provided with liquid outlets for dripping out flocculants that are evenly distributed in a circumferential direction and in a linear array, and the liquid outlets of the liquid inlet plate 111 are evenly distributed in the circumference into four groups, and the liquid inlet plate 111 The four groups of liquid outlets of 1 are all several liquid outlets distributed in a linear array. The aperture of the liquid outlet of the liquid inlet plate 111 gradually increases from the position close to the center of the circle to the position away from the center of the circle. A baffle 112 is fixedly connected to the reaction chamber 110 to cooperate with the liquid inlet plate 111. The baffle 112 is composed of fan-shaped plates evenly distributed in the circumferential direction. When the liquid inlet plate 111 rotates, the liquid outlet of the liquid inlet plate 111 cooperates with the corresponding fan-shaped plate of the baffle 112. The fan-shaped plate of the baffle 112 cuts off the flocculant dripping from the liquid outlet of the liquid inlet plate 111 to prevent the flocculent generated by the continuous addition of flocculant from agglomerating. The housing 101 is provided with a liquid adding component 2 for adding flocculant.

[0033] like Figure 2 , Figure 3 , Figure 6 and Fig. 9 As shown, the liquid adding component 2 includes four slides 201 evenly distributed in the circumferential direction, and the four slides 201 evenly distributed in the circumferential direction are all slidably connected to the outer shell 101. The outer shell 101 is located inside the inner tank 105 in the circumferential direction and is provided with a liquid storage cavity 202 for storing flocculants. The liquid storage cover 1011 is fixedly connected and connected to four liquid inlet pipes 203 evenly distributed in the circumferential direction on one side close to the center of the inner tank 105. A hollow cavity 204 is provided in the rotating shaft 103. The slides 201 are slidably matched with the liquid storage cavity 202. The liquid storage cavity The body 202 is connected with four liquid inlet pipes 203 evenly distributed in the circumference through the liquid storage cover 1011, the slide 201 moves upward to squeeze the flocculant in the liquid storage cavity 202, and the flocculant in the liquid storage cavity 202 is squeezed into the four liquid inlet pipes 203 through the liquid storage cover 1011, the hollow cavity 204 is connected with the four liquid inlet pipes 203 evenly distributed in the circumference, the hollow cavity 204 is connected with the liquid inlet plate 111, and the flocculant in the four liquid inlet pipes 203 enters the liquid inlet plate 111 through the hollow cavity 204.

[0034] like Figure 2 , Figure 3 and Figure 7-Figure 9As shown, the rotating shaft 103 is rotatably connected to four stirring blades 3 evenly distributed circumferentially, and a torsion spring is fixed between the rotating shaft 103 and the four stirring blades 3 evenly distributed circumferentially. The stirring blades 3 are located in the reaction chamber 110. The rotation of the rotating shaft 103 drives the four stirring blades 3 to open to the surroundings through the centrifugal force of rotation. As the rotating shaft 103 rotates, the wastewater and flocculant in the reaction chamber 110 are stirred, so that the wastewater and the flocculant are fully reacted.

[0035] like Figure 2 and Fig. 9 As shown, the outer shell 101 is provided with a water inlet cavity 401 for adding waste water, and the inner liner 105 is provided with four inner water inlets 402 evenly distributed circumferentially. The inner water inlets 402 evenly distributed circumferentially are all matched with the water inlet cavity 401. The inner liner 105 moves downward to drive the four inner water inlets 402 to move downward and block the water inlet cavity 401. When the inner liner 105 moves upward to reset, the four inner water inlets 402 move upward to align with the water inlet cavity 401 for circulation.

[0036] When the operator needs to use the device to treat oat production wastewater in sections, the operator first pours the wastewater into the water inlet cavity 401, and the wastewater enters the inner tank 105 through the water inlet cavity 401 and the inner water inlet 402. At this time, the filter holes of the inner tank 105 and the filter holes of the third filter plate 108 are blocked in an offset manner in the initial state. With the continuous injection of wastewater, the water inside the inner tank 105 gradually increases, and the water level of the wastewater gradually rises, so that the wastewater carries most of the suspended matter such as oat husks upward through the filter holes of the first filter plate 106 and the large-aperture filter holes of the second filter plate 107. At the same time, the inner tank 105 is affected by the gravity of the wastewater and drives the elastic telescopic rod 104 to stretch, and the inner tank 105 drives the third filter plate 108 to move downward. The wastewater is affected by gravity and presses the third filter plate 108 downward. The limit block of the third filter plate 108 moves downward along the limit groove of the rotating shaft 103. At the same time, the inner tank 105 moves downward to make the inner water inlet 402 move downward, and the water inlet cavity 401 and the inner water inlet 402 are misaligned and blocked. At this time, the operator turns on the electric control motor 102 through the control panel, and the output shaft of the electric control motor 102 drives the rotating shaft 103 to rotate clockwise (the rotation direction is Figure 1 The top view of the filter 108 is used as a reference), and the rotating shaft 103 drives the third filter plate 108 to rotate clockwise. When the filter holes of the third filter plate 108 are aligned with the filter holes of the inner tank 105, the wastewater flows downward through the filter holes of the third filter plate 108 and the inner tank 105.

[0037] When the rotating shaft 103 rotates clockwise, the rotating shaft 103 drives the second filter plate 107 to rotate clockwise, and the limiting block of the rotating shaft 103 rotates clockwise along the limiting slot in the first filter plate 106. When the limiting block of the rotating shaft 103 rotates clockwise around the axis of the rotating shaft 103 to the limit position of the limiting slot of the first filter plate 106, the filtering holes of the first filter plate 106 and the large-aperture filtering holes of the second filter plate 107 are misaligned and blocked, and the first filter plate 106 is blocked. The filter holes of the first filter plate 106 are aligned with the small-aperture filter holes of the second filter plate 107. As the wastewater flows downward through the filter holes of the third filter plate 108 and the inner tank 105, the wastewater on the upper side of the first filter plate 106 flows downward through the small apertures of the second filter plate 107. Large suspended matter such as oat husks in the wastewater is retained on its upper side by the filtration of the second filter plate 107, preventing the flocculant from being blocked by the suspended matter when it is added and having difficulty in flocculation reaction with the lower wastewater, thereby affecting the flocculation effect.

[0038] When the wastewater flows downward through the filtering holes of the third filter plate 108 and the inner liner 105, the third filter plate 108 and the filtering holes of the inner liner 105 filter and intercept small impurities such as bottom sediments and particles in the wastewater on the upper side of the third filter plate 108, thereby filtering small impurities such as bottom sediments and particles. After the wastewater flows downward through the filtering holes of the third filter plate 108 and the inner liner 105, the wastewater enters the reaction chamber 110 through the wastewater channel 109. The operator adds the agent through the liquid storage cover 1011. The flocculant is poured into the liquid storage cavity 202, and then the operator manually pushes the slide 201 upwards. The arc block on the upper end of the slide 201 moves upward to squeeze the flocculant in the liquid storage cavity 202, and the flocculant enters the four liquid inlet pipes 203 through the liquid storage cover 1011. The flocculant enters the hollow cavity 204 through the liquid inlet pipe 203 and then flows into the liquid inlet plate 111. The rotation of the rotating shaft 103 drives the liquid inlet plate 111 to rotate, so that the flocculant is evenly thrown from the liquid outlet into the wastewater in the reaction cavity 110.

[0039] During the rotation of the rotating shaft 103, the flocculant is thrown from the liquid outlet into the reaction chamber 110, and the rotating shaft 103 drives the liquid inlet plate 111 to rotate, so that the liquid outlets distributed in the linear array of the liquid inlet plate 111 are intermittently matched with the fan-shaped plates of the corresponding baffles 112. When the fan-shaped plates of the baffles 112 are aligned and blocked with the corresponding liquid outlets of the liquid inlet plate 111, the liquid outlet of the liquid inlet plate 111 cannot flow out the flocculant. When the fan-shaped plates of the baffles 112 are misaligned with the liquid outlet of the liquid inlet plate 111, the flocculant is not allowed to flow out of the liquid outlet of the liquid inlet plate 111. The liquid outlet of the liquid inlet plate 111 is aligned with the circulating flocculant. When the fan-shaped plate edge of the baffle 112 contacts the liquid outlet of the liquid inlet plate 111, along with the rotation of the liquid inlet plate 111, the fan-shaped plate edge of the baffle 112 cuts off the falling flocculant, so that the flocculant intermittently flows into the reaction chamber 110 to react with the wastewater for flocculation, thereby preventing the flocculant from being continuously added, causing the flocs formed therein to form a mass and wrap part of the flocculant, making it unable to fully contact and react with the wastewater, thereby affecting the efficiency of the flocculation reaction.

[0040] During the process of adding flocculant into wastewater, the rotating shaft 103 rotates to drive the stirring blades 3 to rotate. The stirring blades 3 are opened by the centrifugal force and the torsion springs. The four circumferentially distributed stirring blades 3 flip along the torsion springs on the upper side. During the process of flipping and opening upward, the stirring blades 3 continuously stir the wastewater in the reaction chamber 110, so that the flocculant and the wastewater are fully contacted and reacted.

[0041] When the flocculation reaction of the wastewater is completed, the operator discharges and collects the wastewater after the flocculation reaction, and then proceeds to the next step of processing. The operator resets the device through the control panel and turns off the electronic control motor 102, and then discharges the impurities filtered inside and cleans the device for the next use.

[0042] Embodiment 2: Based on embodiment 1, Figure 6 , Fig. 9 and Fig.10 As shown, it also includes a pressing plate 501, which is arranged on the upper side of the rotating shaft 103, and the pressing plate 501 is fixedly connected to a limit pin. A wave groove is arranged on the upper side of the inner liner 105, and the wave groove of the inner liner 105 is located on its inner wall. The limit pin of the pressing plate 501 cooperates with the wave groove of the inner liner 105. When the pressing plate 501 rotates to drive the limit pin to rotate along its center of circle, the limit pin of the pressing plate 501 moves up and down along the wave groove of the inner liner 105. A telescopic sleeve 502 is fixedly connected to the upper end of the rotating shaft 103, and the telescopic sleeve 502 is connected to the hollow cavity 204. The ends of the telescopic sleeve 502 are respectively fixedly connected to the second filter plate 107 and the pressing plate 501, the upper end of the telescopic sleeve 502 is fixedly connected to the lower side of the pressing plate 501, and the lower end of the telescopic sleeve 502 is fixedly connected to the upper side of the second filter plate 107.

[0043] like Figure 2 , Figure 6 and Fig. 9As shown, a frustum slope 6 for guiding wastewater is provided on one side of the housing 101 close to the third filter plate 108 , and the frustum slope 6 is located between the inner tank 105 and the liquid inlet plate 111 .

[0044] like Figure 2-Figure 4 , Figure 7 , Fig.11 and Fig.12 As shown, a floating plate 7 is provided in the reaction chamber 110, and the floating plate 7 is provided with filtering holes. The floating plate 7 cooperates with the stirring blade 3. The torsion spring of the stirring blade 3 in the figure is in a power storage state. After the floating plate 7 moves downward to contact the stirring blade 3, the floating plate 7 drives the stirring blade 3 to flip downward to reset it. After the floating plate 7 moves upward to pass through the upper torsion spring of the stirring blade 3, the floating plate 7 and the stirring blade 3 lose their limit. The stirring blade 3 is opened by the centrifugal force and the force of its torsion spring. The floating plate 7 is fixedly connected to one end of the slide 201 evenly distributed in the circumference close to its center, and the limiting plate 701 is slidably connected in the reaction chamber 110. The upper and lower ends of the limit plate 701 are fixedly connected with limit rings, and the limit plate 701 is slidably matched with the floating plate 7. After the floating plate 7 moves upward and contacts the upper limit ring of the limit plate 701, the floating plate 7 drives the limit plate 701 to move upward through the upper limit ring. The limit plate 701 cooperates with the four wastewater channels 109 evenly distributed in the circumferential direction. The limit plate 701 moves upward to block the four wastewater channels 109. When the floating plate 7 moves downward and drives the limit plate 701 to move downward and reset through the limit ring at the lower end, the limit plate 701 is misaligned with the four wastewater channels 109, so that the four wastewater channels 109 can flow.

[0045] like Figure 7 and Fig.12 As shown, the rotating shaft 103 is slidably connected with a scraper ring 8, which consists of a circular ring in the middle and four scrapers evenly distributed circumferentially. The scraper ring 8 cooperates with the stirring blade 3, and a gap is left between two adjacent stirring blades 3. The scraper of the scraper ring 8 is located between the gap between two adjacent stirring blades 3. The scraper of the scraper ring 8 is used to scrape off the flocs attached to the side of the stirring blade 3. There is a gap between the stirring blade 3 and the rotating shaft 103. The circular ring of the scraper ring 8 is located in the gap between the stirring blade 3 and the rotating shaft 103. The circular ring of the scraper ring 8 is used to scrape off the flocs attached to the inner surface of the stirring blade 3.

[0046] like Figure 1 , Figure 2 , Fig.12 and Fig.13 As shown, the floating plate 7 is fixedly connected with a drainage pipe 901, the drainage pipe 901 is connected with the reaction chamber 110, the drainage pipe 901 passes through the shell 101 and is connected with a water pump, the water pump of the drainage pipe 901 is electrically connected with the control panel, a sewage outlet is provided on the lower side of the shell 101, the sewage outlet of the shell 101 is installed with an electromagnetic valve 902, and the electromagnetic valve 902 is electrically connected with the control panel.

[0047] When the rotating shaft 103 starts to rotate, the rotating shaft 103 drives the pressing plate 501 to rotate, so that the limit pin of the pressing plate 501 moves up and down along the wave groove of the inner tank 105. When the pressing plate 501 moves downward and drives the upper end of the telescopic sleeve 502 to gradually shrink downward, the pressing plate 501 moves downward to squeeze the oat husks between it and the first filter plate 106, squeeze out the moisture in the oat husks, and reduce the moisture content in the oat husks. Then, the pressing plate 501 moves upward and drives the upper end of the telescopic sleeve 502 to gradually extend upward and reset. When the waste water flows downward through the third filter plate 108 and the filter holes of the inner liner 105, the amount of waste water inside the inner liner 105 decreases, the inner liner 105 rises and resets, the water inlet cavity 401 and the inner water inlet 402 are aligned and flow, and the waste water enters the inner liner 105 again through the water inlet cavity 401 and the inner water inlet 402. The inner liner 105 moves downward again under the influence of gravity. As the pressing plate 501 and the inner liner 105 move back and forth up and down, the pressing plate 501 squeezes out the moisture in the oat husks to reduce the moisture content in the oat husks.

[0048] During the process of the water inlet cavity 401 and the inner water inlet 402 being continuously aligned and circulated intermittently, the amount of oat husks between the second filter plate 107 and the third filter plate 108 gradually increases, and the operator controls the electronically controlled motor 102 to reverse counterclockwise through the control panel, and the rotating shaft 103 drives the second filter plate 107 to rotate counterclockwise, and the limiting block of the rotating shaft 103 rotates counterclockwise along the limiting slot in the first filter plate 106. When the limiting block of the rotating shaft 103 rotates counterclockwise around the axis of the rotating shaft 103 to the limit position of the limiting slot of the first filter plate 106, the filtering holes of the first filter plate 106 and the large-aperture filtering holes of the second filter plate 107 are aligned and circulated again, and the oat husks pass through the filtering holes of the first filter plate 106 and the large-aperture filtering holes of the second filter plate 107, and float to the upper side of the first filter plate 106, and then repeat the above movement process, continuously filtering the wastewater and completing the flocculation reaction.

[0049] After the wastewater flows downward to the frustum slope 6 through the third filter plate 108 and the filter holes of the inner tank 105, the wastewater flows into the four wastewater channels 109 through the frustum slope 6. After the wastewater enters the reaction chamber 110 through the four wastewater channels 109, as the amount of wastewater inside the reaction chamber 110 increases, the float plate 7 gradually rises due to the buoyancy, and the rise of the float plate 7 drives the slide 201 to rise. The rise of the slide 201 squeezes the flocculant inside the liquid storage chamber 202 to the liquid inlet plate 111 through the liquid inlet pipe 203 and the hollow cavity 204 through the above steps, and the flocculant is intermittently discharged into the wastewater through the liquid outlet of the liquid inlet plate 111, so that the injection amount of the flocculant is proportional to the amount of wastewater inside the reaction chamber 110.

[0050] During the rising process of the floating plate 7, the scraper of the scraper ring 8 moves upward along the gap between the stirring blades 3 distributed in the circumferential array due to the buoyancy, and the rotating shaft 103 drives the scraper ring 8 to rotate. After the flocculant and the wastewater pass through the filtering holes of the floating plate 7, the wastewater and the flocculant are evenly mixed through the stirring of the scraper ring 8 which is always located at the lower side of the floating plate 7. When the floating plate 7 rises to the torsion spring of the stirring blade 3, the rotating shaft 103 rotates so that the stirring blade 3 is opened by the centrifugal force, and cooperates with the torsion spring to drive the stirring blade 3 to open. During the opening process of the stirring blade 3, the rotating shaft 103 drives the stirring blade 3 to rotate to further evenly mix the wastewater and the flocculant.

[0051] When the floating plate 7 rises to contact the limiting ring on the upper end of the limiting plate 701, the floating plate 7 rises and drives the limiting plate 701 to move upward, and the wastewater in the reaction chamber 110 is filled. At this time, the floating plate 7 drives the limiting plate 701 to block the four wastewater channels 109, and the wastewater no longer enters the reaction chamber 110. The flocs generated in the reaction chamber 110 begin to settle, and the operator turns on the water pump of the drainage pipe 901. The water pump draws the water inside the reaction chamber 110 to the outside through the drainage pipe 901 and is collected by the operator. With the reduction of the wastewater inside the reaction chamber 110, the water level inside the reaction chamber 110 drops, and the floating plate 7 drops due to the buoyancy. When the floating plate 7 passes through the circumferentially distributed stirring blades 3, the floating plate 7 drives the stirring blade 3 to flip downward and reset by relying on its torsion spring, and drives the scraper ring 8 to move downward at the same time. The scraper ring 8 contacts the inner side of the stirring blade 3, and the scraper ring 8 scrapes off the flocs on the inner side of the stirring blade 3 to prevent the flocs from adhering to the inner side of the stirring blade 3 and affecting the next flocculation reaction. At the same time, the floating plate 7 scrapes off the flocs adhering to the outer side of the stirring blade 3. As the floating plate 7 moves downward, the floating plate 7 gathers the flocs deposited at the bottom to the bottom of the reaction chamber 110. The operator opens the solenoid valve 902 through the control panel. As the scraper ring 8 rotates, the flocs are discharged from the reaction chamber 110 through the sewage outlet of the shell 101 to prevent them from affecting the next flocculation reaction.

[0052] After the flocs are discharged from the reaction chamber 110, the floating plate 7 continues to move downward under the action of buoyancy, and the floating plate 7 drives the limiting ring on the lower side of the limiting plate 701 to move downward. The floating plate 7 drives the limiting plate 701 to move downward so that the wastewater channel 109 is staggered and circulated. The above steps are repeated to achieve uninterrupted filtration and flocculation reaction of the wastewater.

[0053] Embodiment 3: Based on embodiment 2, Figure 1 and Fig.13As shown, it also includes a water inlet pipe 1001, which is fixed to the middle of the shell 101. The water inlet pipe 1001 passes through the shell 101 through four pipes evenly distributed in the circumferential direction and cooperates with the wastewater channel 109 and the inner tank 105 to pour water into the reaction chamber 110 through the wastewater channel 109. When the reaction chamber 110 is full of water, the water flows through the filter holes of the inner tank 105 and the third filter plate 108, and the water flows into the interior of the inner tank 105 to achieve cleaning of the device. 1001 is connected to a water inlet pump, and the water inlet pump of the water inlet pipe 1001 is electrically connected to the control panel. A guide plate 1002 is fixedly connected to the right side of the outer shell 101, and the guide plate 1002 cooperates with the inner tank 105. A sewage outlet is arranged on the right side of the inner tank 105. When the guide plate 1002 is aligned with the sewage outlet of the inner tank 105, the water flow carries impurities and is discharged through the sewage outlet of the inner tank 105 and the guide plate 1002. An electric control valve is installed on the right side of the inner tank 105, and the electric control valve of the inner tank 105 is electrically connected to the control panel.

[0054] When the device is stopped from being used to treat wastewater, the operator turns off the power through the control panel and cleans the device for the next use. When cleaning the device, the operator first turns on the water inlet pump of the water inlet pipe 1001 through the control panel. The water inlet pump supplies water to the frustum slope 6 inside the shell 101 through the water inlet pipe 1001. The water flows into the wastewater channel 109 through the frustum slope 6, and the water flows into the reaction chamber 110 to flush the inside. When the inside of the reaction chamber 110 is full of water, the water flows upward to flush the filter holes of the inner tank 105 and the third filter plate 108, and backwashes the filter holes of the inner tank 105 and the third filter plate 108 to prevent them from being blocked. Then the operation The operator opens the electric control valve of the guide plate 1002, and the water flow carries the particles and other impurities on the upper side of the third filter plate 108 through the guide plate 1002 and is discharged from the inner tank 105 and the outer shell 101. The particles and other impurities and sewage are collected by the operator. Then the operator controls the output shaft of the electric control motor 102 to rotate counterclockwise through the control panel, so that the large-aperture filter holes of the first filter plate 106 are aligned with the large-aperture filter holes of the second filter plate 107, and the oat husks fall to the upper side of the third filter plate 108, and then the oat husks are carried out by the water flow and collected by the operator. After the operator finishes cleaning the device, the operator drains the water in the device, and resets the device through the control panel to turn off the power for the next use.
