Description

Technical Field

[0001] The present invention relates to the field of sewage treatment, and more specifically, to a sewage circulation treatment system for a feed production plant. Background Art

[0002] Feed is a kind of feed for animal breeding processed with crop grains as the main raw material (such as corn, etc.). It is mostly in granular form. Specifically, in the process of feed production and processing, after the material is formulated, it goes through many processing procedures such as ripening, granulation, and drying to obtain the finished feed.

[0003] During the process of feed processing and production, a large amount of sewage, sludge and pollutants will be generated. Specifically, the sewage and sludge not only contain a large amount of organic matter, inorganic salts, and feed residues and other substances, and can only meet the discharge standards after environmental protection treatment.

[0004] Due to the residues contained in the sewage and sludge, it is necessary to filter the residues in advance. The traditional sewage treatment device mainly filters the residues in the sewage through a filter plate. However, the filter plate is fixed in the sewage treatment equipment, and the position where the sewage contacts the filter plate remains unchanged, which will cause the accumulation of residues at the filtering position, not only limiting the use area of the filter plate, but also having low filtering efficiency. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a sewage circulation treatment system for a feed production plant.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

A solenoid valve is fixedly connected to the middle of the lower surface of the filter box, and a filter screen is arranged at the input end of the solenoid valve.

[0010] Furthermore, the top of the vertical rod penetrates through the inside of the C-shaped frame and the first conical cover. The vertical rod and the C-shaped frame slide relative to each other. The C-shaped frame is made of wrought iron. A sewage discharge port is opened at the middle of the inner bottom of the filter cylinder, and the sealing plug is inserted into the sewage discharge port.

[0011] Furthermore, a quantitative feeding assembly for storing flocculant is arranged at the edge of the upper surface of the sealing cover. The quantitative feeding assembly includes a storage cylinder fixed at the edge of the upper surface of the sealing cover. A fixed sleeve is fixedly connected to the inner bottom of the storage cylinder. Second liquid outlets are axially symmetrically arranged on the outer surface of the fixed sleeve. A telescopic sleeve is slidably connected inside the fixed sleeve. First liquid outlets are axially symmetrically arranged on the outer surface of the telescopic sleeve near the top. The bottom of the telescopic sleeve extends to the inside of the filter box, and a driving component is arranged on the outer surface of the filter cylinder.

[0012] Furthermore, the driving component includes a driving ring fixed on the outer surface of the filter cylinder. Two triangular blocks are axially symmetrically arranged at the top of the driving ring. A spring is sleeved on the outer surface of the telescopic sleeve, and a fixed ring is fixedly connected to the outer surface of the telescopic sleeve near the bottom.

[0013] Furthermore, the fixed ring is located above the driving ring. The filter cylinder is fixedly connected to the driving ring through a cross bar. The spring is located above the fixed ring, and the top of the spring contacts the inner top of the filter box.

[0014] Furthermore, an ozone disinfection assembly is arranged near the bottom of the outer surface of the filter box. The ozone disinfection assembly includes a first air pump fixed near the bottom of the outer surface of the filter box and a stirring shaft fixed on the lower surface of the filter cylinder. The output end of the first air pump is fixedly connected to a connecting pipe. Three air distribution circular pipes are arranged on the outer surface of the connecting pipe. First nozzles are evenly arranged on the outer surface of the air distribution circular pipe. Stirring blades are arranged on the outer surface of the stirring shaft.

[0015] Furthermore, the stirring blades are located above the air distribution circular pipes. A C-shaped plate is fixedly connected to the lower surface of the filter cylinder, and the stirring shaft is fixedly connected to the bottom of the C-shaped plate. The three air distribution circular pipes are all concentric circles. The inside of the air distribution circular pipe and the connecting pipe are interconnected. The input end of the first air pump is connected to an ozone generator.

[0016] Furthermore, an ozone recovery component is arranged near the top of the inner surface of the filter frame, and the recovery component includes an annular tube fixed on the inner surface of the filter frame near the top, a second air pump fixed on the outer surface of the filter frame near the top, and a second conical cover fixed in the middle of the inner surface of the filter frame, the input end of the second air pump is fixedly connected to the air inlet pipe, the output end of the second air pump is fixedly connected to the bellows, and second nozzles are evenly arranged on the outer surface of the annular tube.

[0017] Furthermore, one end of the air inlet pipe extends to the interior of the filter frame and to the bottom of the second conical cover, the second conical cover is located above the stirring blade, the stirring shaft passes through the interior of the second conical cover and rotates and adapts with each other, and the other end of the corrugated pipe extends to the interior of the filter frame and is interconnected with the annular tube.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. This solution is provided with a filter assembly, and the first conical cover can be moved up and down inside the filter cylinder through transmission. Before the wastewater passes through the fixed circular frame and enters the filter cylinder, the wastewater contacts the surface of the first conical cover. The up and down movement of the first conical cover will break up the wastewater and spread it around. Since the first conical cover continuously moves up and down, the height of the contact position between the wastewater and the filter cylinder can be changed, so that the wastewater can contact all areas of the inner surface of the filter cylinder, so that the rate of filtering the wastewater is faster, and the use area of ​​the filter cylinder is effectively increased. At the same time, with the rotating filter cylinder, the centrifugal force can filter the wastewater more quickly.

[0019] 2. This scheme is provided with a quantitative feeding component. The triangular block pushes the telescopic sleeve upward, so that the first liquid outlet moves upward and gradually overlaps with the second liquid outlet. The flocculant inside the storage barrel enters the interior of the telescopic sleeve through the second liquid outlet and the first liquid outlet, and drips from the interior of the telescopic sleeve into the wastewater inside the filter frame. The suspended matter in the wastewater combines with the flocculant to form flocs, which can be filtered through a filter screen in subsequent treatment, thereby effectively removing the suspended matter in the wastewater. The amount of flocculant falling each time is roughly constant, and the addition method is intermittent addition, thereby effectively avoiding excessive addition of flocculant, causing part of the flocculant to be unable to function, resulting in waste of flocculant.

[0020] 3. This solution is provided with an ozone disinfection component. The first nozzle sprays a large number of bubbles. Since the first nozzles are distributed in various positions, the bubbles are in full contact with the wastewater, and organic matter in the wastewater is removed while the wastewater is disinfected. The stirring blades will stir the bubbles and break up large bubbles into small bubbles, which can not only effectively increase the contact area between ozone and water, but also slow down the speed of ozone movement, increase the contact time between ozone and water, and treat organic matter more thoroughly.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 8 , a sewage recycling treatment system for a feed production plant, including a filter frame 1. A sealing cover 2 is fixedly connected to the top of the filter frame 1. A filter assembly 4 for changing the sewage filtration position is arranged at the middle of the upper surface of the sealing cover 2.

[0025] As Figure 2-4 shown, the filter assembly 4 includes a fixed circular frame 41 fixed to the inner top of the filter frame 1 and a driving motor 43 fixed to one side of the upper surface of the sealing cover 2. The output end of the driving motor 43 is fixedly connected to a gear 44. A wavy groove 413 is opened inside the fixed circular frame 41. A moving rod 410 is slidably connected inside the wavy groove 413. A fixed rod 412 is fixedly connected to the outer surface of the moving rod 410. A first conical cover 411 is fixedly connected to the bottom of the fixed rod 412. A filter cylinder 45 is rotatably connected to the outer surface of the driving motor 43. An annular rack 42 is fixedly connected to the edge of the upper surface of the filter cylinder 45. A sealing plug 46 is inserted into the middle of the inner bottom of the filter cylinder 45. A magnet 48 is fixedly connected to the top of the sealing plug 46. A vertical rod 49 is connected to the top of the magnet 48. A U-shaped frame 47 is fixedly connected to the inner bottom of the filter cylinder 45.

[0026] The output end of the driving motor 43 extends to the inside of the filter frame 1. The gear 44 and the annular rack 42 are at the same horizontal height and are meshed with each other. A solenoid valve 6 is fixedly connected to the middle of the lower surface of the filter frame 1. A filter screen is arranged at the input end of the solenoid valve 6.

[0027] The top of the vertical rod 49 penetrates through the inside of the U-shaped frame 47 and the first conical cover 411. The vertical rod 49 and the vertical rod 49 slide with the U-shaped frame 47. The material of the U-shaped frame 47 is metal iron. A sewage discharge port is opened in the middle of the inner bottom of the filter cylinder 45. The sealing plug 46 is inserted into the inside of the sewage discharge port.

[0028] When pouring the feed wastewater into the interior of the filter frame 1 through the fixed circular frame 41, the drive motor 43 is turned on at this time to drive the gear 44 to work. The gear 44 will drive the annular rack 42 meshed with it to rotate. The annular rack 42 drives the filter cylinder 45 to rotate on the outer surface of the fixed circular frame 41. The filter cylinder 45 drives the C-shaped frame 47 to rotate synchronously. The C-shaped frame 47 drives the first conical cover 411 to rotate through the vertical rod 49. The first conical cover 411 drives the moving rod 410 to rotate inside the wavy groove 413 through the fixed rod 412. Both ends of the moving rod 410 move up and down inside the wavy groove 413. The moving rod 410 drives the first conical cover 411 to move up and down inside the filter cylinder 45 through the fixed rod 412. Before the wastewater enters the interior of the filter cylinder 45 through the fixed circular frame 41, the wastewater contacts the surface of the first conical cover 411. The up and down movement of the first conical cover 411 will disperse the wastewater, causing the wastewater to spread around. Since the first conical cover 411 continuously moves up and down, the height of the contact position between the wastewater and the filter cylinder 45 can be changed, enabling the wastewater to contact all areas of the inner surface of the filter cylinder 45, making the rate of filtering the wastewater faster, effectively increasing the usage area of the filter cylinder 45. At the same time, in cooperation with the rotating filter cylinder 45, the centrifugal force can filter the wastewater more quickly. When cleaning the inner surface of the filter cylinder 45 subsequently, the vertical rod 49 can be pulled upward to pull out the sealing plug 46 from the sewage outlet of the filter cylinder 45, and the废渣 cleaned out is discharged from the sewage outlet.

[0029] As Figure 5-6 shown, a quantitative feeding component 3 for storing flocculant is provided at the edge of the upper surface of the sealing cover 2. The quantitative feeding component 3 includes a storage cylinder 31 fixed at the edge of the upper surface of the sealing cover 2. A fixed sleeve 32 is fixedly connected to the inner bottom of the storage cylinder 31. Second liquid outlets 37 are axially symmetrically opened on the outer surface of the fixed sleeve 32. A telescopic sleeve 33 is slidably connected inside the fixed sleeve 32. First liquid outlets 34 are axially symmetrically opened on the outer surface of the telescopic sleeve 33 near the top. The bottom of the telescopic sleeve 33 extends into the interior of the filter frame 1. A driving component is provided on the outer surface of the filter cylinder 45.

[0030] The driving component includes a driving ring 39 fixed on the outer surface of the filter cylinder 45. Two triangular blocks 38 are axially symmetrically opened at the top of the driving ring 39. A spring 35 is sleeved on the outer surface of the telescopic sleeve 33. A fixed ring 36 is fixedly connected to the outer surface of the telescopic sleeve 33 near the bottom.

[0031] The fixed ring 36 is located above the driving ring 39. The filter cylinder 45 is fixedly connected to the driving ring 39 through a cross bar. The spring 35 is located above the fixed ring 36. The top of the spring 35 contacts the inner top of the filter frame 1.

[0032] After the wastewater residue is filtered, the wastewater contains a large amount of fine suspended matter, which cannot be effectively filtered by the filter. In order to remove the suspended matter and colloidal substances in the wastewater, while the filter cylinder 45 performs the rotating filtration, the filter cylinder 45 drives the second liquid outlet 37 to rotate synchronously, and the second liquid outlet 37 drives the two triangular blocks 38 to perform circular motion. When the triangular block 38 moves to the fixed ring 36, the hypotenuse of the triangular block 38 contacts the edge of the fixed ring 36, and the triangular block 38 continues to move to push the fixed ring 36 and the telescopic sleeve 33 to move upward as a whole, and the fixed ring 36 squeezes the spring 35, and the telescopic sleeve 33 drives the first liquid outlet 34 to move upward and gradually overlap with the second liquid outlet 37. The flocculant inside the storage barrel 31 enters the telescopic sleeve 33 through the second liquid outlet 37 and the first liquid outlet 34, and drips from the telescopic sleeve 33 into the wastewater inside the filter frame 1. The suspended matter in the wastewater combines with the flocculant to form flocs, which can be filtered through the filter screen in subsequent treatment, so that the suspended matter in the wastewater can be effectively removed; When the triangular block 38 continues to move, the triangular block 38 leaves from under the telescopic sleeve 33. At this time, the telescopic sleeve 33 is no longer supported by the triangular block 38. Under the elastic force of the spring 35, the fixed ring 36 and the telescopic sleeve 33 are pushed to quickly reset. The telescopic sleeve 33 will drive the first liquid outlet 34 and the second liquid outlet 37 to stagger with each other. The telescopic sleeve 33 effectively seals the second liquid outlet 37, and the flocculant inside the storage barrel 31 no longer flows. When the next triangular block 38 moves to under the telescopic sleeve 33 again, the second liquid outlet 37 and the first liquid outlet 34 will overlap with each other again, so that the flocculant inside the storage barrel 31 flows again, so that the amount of flocculant falling each time is roughly constant, and the addition method is intermittent addition, thereby effectively avoiding excessive addition of flocculant, resulting in waste of flocculant caused by the inability of some flocculants to function.

[0033] like Figure 2 , 7 As shown in Figure 8, an ozone disinfection component 5 is arranged near the bottom of the outer surface of the filter frame 1. The ozone disinfection component 5 includes a first air pump 51 fixed on the outer surface of the filter frame 1 near the bottom and a stirring shaft 56 fixed on the lower surface of the filter cylinder 45. The output end of the first air pump 51 is fixedly connected to a connecting pipe 54. The outer surface of the connecting pipe 54 is provided with three groups of air distribution circular tubes 52. The outer surface of the air distribution circular tubes 52 is evenly provided with first nozzles 53. The outer surface of the stirring shaft 56 is provided with stirring blades 57.

[0034] The stirring blade 57 is located above the air distribution circular tube 52, a C-shaped plate is fixedly connected to the lower surface of the filter cylinder 45, and a stirring shaft 56 is fixedly connected to the bottom of the C-shaped plate. The three air distribution circular tubes 52 are all concentric circles, and the interiors of the air distribution circular tubes 52 and the connecting tubes 54 are interconnected. The input end of the first air pump 51 is connected to the ozone generator.

[0035] After filtering and flocculants, wastewater can remove most of the water-insoluble substances, but feed wastewater also contains a large amount of organic matter. If the organic matter is not removed, the wastewater discharged to the outside will damage the water ecology and produce a series of hazards such as toxic gases. When treating wastewater, ozone is transported to the inside of the connecting pipe 54 through the first air pump 51, and then transported to the inside of the gas distribution circular pipe 52 through the connecting pipe 54 in sequence, and a large number of ozone bubbles are sprayed through the first nozzle 53. Since the first nozzle 53 is distributed at various positions, the bubbles are fully in contact with the wastewater, the organic matter in the wastewater is removed and the wastewater is disinfected. At the same time, the stirring shaft 56 will rotate synchronously with the filter cylinder 45, and the stirring shaft 56 drives the stirring blade 57 to rotate, and the stirring blade 57 stirs the wastewater. The stirring blade 57 stirs the bubbles, and can break up large bubbles into small bubbles, which can not only effectively increase the contact area between ozone and water, but also slow down the speed of ozone movement, increase the contact time between ozone and water, and treat organic matter more thoroughly.

[0036] like Figure 2 , 7 As shown in Figure 8, an ozone recovery component 55 is arranged near the top of the inner surface of the filter frame 1, and the recovery component 55 includes an annular tube 554 fixed on the inner surface of the filter frame 1 near the top, a second air pump 551 fixed on the outer surface of the filter frame 1 near the top, and a second conical cover 556 fixed in the middle of the inner surface of the filter frame 1, the input end of the second air pump 551 is fixedly connected to the air inlet pipe 552, the output end of the second air pump 551 is fixedly connected to the bellows 553, and the outer surface of the annular tube 554 is evenly provided with second nozzles 555.

[0037] One end of the air inlet pipe 552 extends to the interior of the filter frame 1 and extends to the bottom of the second conical cover 556. The second conical cover 556 is located above the stirring blade 57. The stirring shaft 56 passes through the interior of the second conical cover 556 and rotates and adapts with each other. The other end of the bellows 553 extends to the interior of the filter frame 1 and is interconnected with the annular tube 554.

[0038] When ozone comes into contact with rainwater, organic matter in the water can be removed. When ozone separates from the water and floats into the interior of the filter frame 1, the ozone is directly discharged to the outside, and the utilization rate of ozone is low. When ozone escapes from the water, most of the ozone will gather at the inner top of the second conical cover 556. The second air pump 551 is turned on to extract the unconsumed ozone gathered at the inner top of the second conical cover 556 through the air inlet pipe 552, and transport it to the inside of the annular tube 554 through the bellows 553, and then the ozone is sprayed onto the outer surface of the filter cylinder 45 through the second nozzle 555, so as to preliminarily treat the organic matter in the wastewater filtered by the filter cylinder 45. At the same time, the airflow generated by the second nozzle 555 can blow the blocked filter holes of the filter cylinder 45 to blow off the impurities in the filter holes, so as to clean the filter cylinder 45 to ensure the filtering efficiency of the filter cylinder 45.

[0039] Method of use: Turn on the driving motor 43 to drive the gear 44 to work. Through transmission, the first conical cover 411 drives the moving rod 410 to rotate inside the wavy groove 413 through the fixed rod 412. The two ends of the moving rod 410 are in the same upper and lower positions inside the wavy groove 413. The moving rod 410 drives the first conical cover 411 to move up and down inside the filter cylinder 45 through the fixed rod 412. Before the wastewater passes through the fixed circular frame 41 and enters the inside of the filter cylinder 45, the wastewater contacts the surface of the first conical cover 411. The up and down movement of the first conical cover 411 will break up the wastewater and make it spread all around. Since the first conical cover 411 moves up and down continuously, the height of the contact position between the wastewater and the filter cylinder 45 can be changed, so that the wastewater can contact each area of ​​the inner surface of the filter cylinder 45, so that the rate of filtering the wastewater is faster. Since the filter cylinder 45 drives the second liquid outlet 37 to rotate synchronously, the second liquid outlet 37 drives the two triangular blocks 38 to make a circular motion. When the triangular block 38 moves to the fixed ring 36, the hypotenuse of the triangular block 38 contacts the edge of the fixed ring 36, and the triangular block 38 continues to move to push the fixed ring 36 and the telescopic sleeve 33 to move upward as a whole. The fixed ring 36 squeezes the spring 35, and the telescopic sleeve 33 drives the first liquid outlet 34 to move upward and gradually overlap with the second liquid outlet 37. When the first liquid outlet 34 and the second liquid outlet 37 overlap with each other, the flocculant inside the storage barrel 31 enters the interior of the telescopic sleeve 33 through the second liquid outlet 37 and the first liquid outlet 34, and drips from the interior of the telescopic sleeve 33 into the wastewater inside the filter frame 1; Ozone is transported to the inside of the connecting pipe 54 through the first air pump 51, and then transported to the inside of the air distribution circular pipe 52 in turn through the connecting pipe 54. At this time, ozone is sprayed out through multiple first nozzles 53, and the first nozzles 53 spray out a large number of bubbles. The stirring shaft 56 drives the stirring blades 57 to rotate, and the stirring blades 57 stir the wastewater. The stirring blades 57 will stir the bubbles and can break up large bubbles into small bubbles, which can not only effectively increase the contact area between ozone and water.

[0040] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
