Description

Technical Field

[0001] This utility model belongs to the field of bar screen technology, and in particular relates to an internal flow type ultrafine bar screen. Background Technology

[0002] A bar screen is a solid-liquid separation device that can continuously remove impurities from fluids. It is an indispensable special equipment in the production processes of industries such as urban sewage treatment, waterworks, power plant inlets, textiles, food processing, papermaking, and leather. It is a widely used solid-liquid screening device in China.

[0003] For example, Chinese patent CN210448295U discloses a technology in the field of internal flow perforated plate membrane bar screens. This technology addresses the problem that existing internal flow perforated plate membrane bar screens have low removal efficiency for fine fibrous materials such as hair in water, thus reducing their interception effect. The outer frame has a main motor mounted on one side, and a flushing port is located on one side above the main motor. A filter screen is installed inside the outer frame, and drive chains are located on both sides of the filter screen. Two drive sprockets are located inside the drive chains. A slag discharge pipe is located below the main shaft, and a slag discharge port is located at one end of the slag discharge pipe. Mounting brackets are located on both sides of the outer frame, and a water inlet is located at one end of the outer frame.

[0004] The aforementioned patent has the following problems:

[0005] This patented device has some drawbacks in use. For example, due to the varying depths of different ditches, operators need to adjust the angle of the bar screen according to the different depths, making operation cumbersome. Furthermore, if the residual waste on the bar screen is not cleaned promptly after use, it will emit an unpleasant odor over time, causing discomfort. Therefore, we propose an internal flow ultrafine bar screen. Utility Model Content

[0006] The purpose of this invention is to provide an internal flow type ultrafine bar screen to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides an internal flow type ultrafine bar screen, comprising:

[0008] A fixed base, in which a rotating shell is rotatably installed, and in which two rotating rollers are rotatably installed, a conveyor belt is driven between the two rotating rollers, and several grid plates are fixedly installed on the conveyor belt. A collection box is rotatably installed on the rotating shell and on one side of the fixed base.

[0009] A drive assembly, located within a fixed base, is used to drive the rotating housing to rotate.

[0010] A rectangular box is fixedly installed on one side of a rotating shell and below a collection box. A cleaning brush is rotatably installed inside the rectangular box. A water pipe is fixedly installed on the top of the rectangular box. Several nozzles are fixedly installed on one side of the water pipe. A water pump is fixedly installed on the rectangular box and on one side of the cleaning brush. The water outlet of the water pump is fixed to the water pipe. A material box is fixedly installed on the water inlet of the water pump through a connecting pipe. A baffle is fixedly installed at the bottom of the rotating shell.

[0011] A power assembly, located on a rotating housing, is used to drive the cleaning brush and one of the rotating rollers to rotate.

[0012] In this technical solution, the drive component drives the rotating shell to rotate within the fixed base until the baffle on the rotating shell falls to the bottom of the ditch. At this point, the motor stops, ensuring that personnel can adjust the tilt angle of the rotating shell according to the different depths of the ditch, thus better cleaning the garbage in the ditch. The operation is simple. Then, the power component drives the cleaning brush and one of the rotating rollers to rotate. The rotation of the rotating roller drives the transmission wheel two to rotate, which in turn drives the belt to drive the transmission wheel one to rotate. The rotation of the transmission wheel one drives the cleaning brush to rotate. The conveyor belt drives several grid plates to move upward. The grid plates can carry the garbage in the ditch out and transport it upward on the conveyor belt until the garbage falls into the collection box. At the same time, the spacing between the grid bars is 0.2-2mm, which can filter out larger impurities in the water as well as smaller particulate matter, fibrous materials, and hair.

[0013] After the entire device is used, the water pump can be started through the water pipes. The water pump draws the cleaning solution from the loading tank and delivers it into the water pipes through the connecting pipes. The solution is then sprayed out from several nozzles on the water pipes. These nozzles can evenly spray the cleaning solution onto the surface of the conveyor belt. At the same time, the rotating cleaning brush can clean the surface of the conveyor belt. The conveyor belt drive ensures that the conveyor belt can be thoroughly cleaned. This ensures that the surface of the conveyor belt can be cleaned in a timely manner after the entire device is used, so that no garbage remains on the surface of the conveyor belt, and thus no unpleasant odor is emitted.

[0014] In the above technical solution, the driving component further includes:

[0015] A rotating groove is formed inside a fixed base and located on one side of a rotating shell. A worm gear is rotatably installed inside the rotating groove. One end of the worm gear passes through one side of the rotating groove and is fixed to the rotating shell. A worm is meshed with the bottom of the worm gear and located inside the rotating groove. A second motor is fixedly installed inside the fixed base and located on one side of the rotating groove. The output end of the second motor extends into the rotating groove and is coaxially connected to the worm.

[0016] In this technical solution, starting motor two causes the output shaft of motor two to drive the worm gear to rotate. Under the action of meshing, the rotation of the worm gear drives the worm wheel to rotate in the rotating groove. The rotation of the worm wheel will drive the rotating shell to rotate in the fixed seat until the baffle on the rotating shell falls to the bottom of the ditch. At this time, motor two is stopped to ensure that personnel can adjust the tilt angle of the rotating shell according to the different depths of the ditch, so as to better clean up the garbage in the ditch.

[0017] In the above technical solution, the worm gear is rotatably connected to the rotating groove, and the output shaft of the second motor is rotatably connected to the fixed seat and the rotating groove.

[0018] In this technical solution, it is ensured that the worm gear can rotate normally in the rotating slot, and that the output shaft of the second motor can rotate normally in the fixed seat and the rotating slot.

[0019] In the above technical solution, the power component further includes:

[0020] A second transmission wheel is rotatably mounted on one side of the rotating housing and located at one end of one of the rotating rollers. One end of the second transmission wheel passes through one side of the rotating housing and is coaxially connected to one of the rotating rollers. A first transmission wheel is rotatably mounted on one side of the rectangular box. One end of the first transmission wheel passes through one side of the rectangular box and is coaxially connected to the cleaning brush. A belt is installed between the first and second transmission wheels for transmission. A first motor is fixedly mounted on the other side of the rotating housing and located at the other end of one of the rotating rollers. The output end of the first motor passes through the other side of the rotating housing and is coaxially connected to one of the rotating rollers.

[0021] In this technical solution, starting motor one causes its output shaft to drive one of the rotating rollers to rotate. This rotation drives the conveyor belt, which in turn drives another rotating roller. This rotating roller, in turn, drives a second transmission wheel, which in turn drives a belt, which in turn drives a first transmission wheel, which in turn drives a cleaning brush. The conveyor belt then moves several grating plates upwards, carrying garbage out of the ditch and conveying it upwards on the conveyor belt until it falls into the collection box. The grating plates have a spacing of 0.2-2mm, which filters out larger impurities in the water as well as smaller particulate matter, fibers, and hair. Simultaneously, the rotating cleaning brush cleans the surface of the conveyor belt. The conveyor belt drive ensures that the conveyor belt is thoroughly cleaned after use, guaranteeing that no garbage remains on the surface and preventing unpleasant odors.

[0022] In the above technical solution, furthermore, the output shaft of the motor is rotatably connected to the rotating housing.

[0023] In this technical solution, it is ensured that the output shaft of motor one can rotate normally within the rotating housing.

[0024] In the above technical solution, further, the periphery of the cleaning brush contacts the conveyor belt, one end of the water pipe is threadedly connected to the water pump, and the water pipe is connected to the water outlet of the water pump.

[0025] In this technical solution, it is ensured that the rotating cleaning brush can clean the surface of the conveyor belt, the structure of the water pipe and the water pump is stable, and the water pump can deliver the cleaning fluid into the water pipe.

[0026] In the above technical solution, the baffle has a triangular cross-section.

[0027] In this technical solution, it is ensured that the baffle can effectively block the garbage above the baffle.

[0028] The beneficial effects of this utility model are:

[0029] 1. This internal flow ultrafine bar screen machine, through a set drive component, drives the rotating shell to rotate within the fixed base until the baffle on the rotating shell falls to the bottom of the ditch. At this point, the motor stops, ensuring that personnel can adjust the tilt angle of the rotating shell according to different ditch depths, thereby better cleaning the garbage in the ditch. It is also easy to operate. Then, through a set power component, the power component drives the cleaning brush and one of the rotating rollers to rotate. The rotation of the rotating roller drives the transmission wheel two to rotate, and the rotation of the transmission wheel two drives the belt to rotate, which in turn drives the transmission wheel one to rotate. The rotation of the transmission wheel one drives the cleaning brush to rotate, and the conveyor belt drives several bar screens to move upward. The bar screens carry the garbage in the ditch out and convey it upward on the conveyor belt until the garbage falls into the collection box. At the same time, the spacing between the bar screens is 0.2-2mm, which can filter out larger impurities in the water as well as smaller particulate matter, fibrous materials, and hair.

[0030] 2. This internal flow ultrafine bar screen machine, through the installed water pipes, allows the water pump to be started after the entire device is used. The water pump draws the cleaning solution from the loading tank through the connecting pipe and delivers it into the water pipe, where it is then sprayed out from several nozzles. These nozzles evenly spray the cleaning solution onto the surface of the conveyor belt, while the rotating cleaning brushes clean the surface of the conveyor belt. The conveyor belt drive ensures that the conveyor belt is thoroughly cleaned, ensuring that the surface of the conveyor belt can be cleaned promptly after the entire device is used, preventing the residue from remaining on the surface and thus eliminating unpleasant odors.

[0050] The system is designed with a drive assembly that rotates the rotating shell 2 within the fixed base 1 until the baffle 20 on the rotating shell 2 falls to the bottom of the ditch. At this point, the motor 19 stops, ensuring that personnel can adjust the tilt angle of the rotating shell 2 according to the depth of the ditch, thus better cleaning the garbage in the ditch. The system is easy to operate. The power assembly then drives the cleaning brush 8 and one of the rotating rollers 3 to rotate. The rotation of the rotating roller 3 drives the transmission wheel 13 to rotate, which in turn drives the belt 14 to rotate. The belt 14 drives the transmission wheel 12 to rotate, which in turn drives the cleaning brush 8 to rotate. The conveyor belt 4 drives several grid plates 5 to move upward. The grid plates 5 can carry the garbage out of the ditch and transport it upward on the conveyor belt 4 until the garbage falls into the collection box 6.

[0051] After the entire device is used, the water pump 11 can be started through the water pipe 9. The water pump 11 can draw the cleaning liquid from the loading tank and transport it into the water pipe 9 through the connecting pipe. Then, it can be sprayed out from several nozzles 10 on the water pipe 9. The nozzles 10 can spray the cleaning liquid evenly on the surface of the conveyor belt 4.

The output end of the second motor 19 extends into the rotating groove 16 and is coaxially connected to the worm 18.

[0054] When the second motor 19 is started, its output shaft drives the worm gear 18 to rotate. Under the action of meshing, the rotation of the worm gear 18 drives the worm wheel 17 to rotate in the rotating groove 16. The rotation of the worm wheel 17 drives the rotating shell 2 to rotate in the fixed seat 1 until the baffle 20 on the rotating shell 2 falls to the bottom of the ditch. At this time, the second motor 19 is stopped to ensure that personnel can adjust the tilt angle of the rotating shell 2 according to the different depths of the ditch, so as to better clean up the garbage in the ditch.

[0057] This embodiment provides an internal flow type ultrafine bar screen machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a power component:

[0058] A second transmission wheel 13 is rotatably mounted on one side of the rotating housing 2 and located at one end of one of the rotating rollers 3. One end of the second transmission wheel 13 passes through one side of the rotating housing 2 and is coaxially connected to one of the rotating rollers 3. A first transmission wheel 12 is rotatably mounted on one side of the rectangular box 7. One end of the first transmission wheel 12 passes through one side of the rectangular box 7 and is coaxially connected to the cleaning brush 8. A belt 14 is installed between the first transmission wheel 12 and the second transmission wheel 13. A first motor 15 is fixedly mounted on the other side of the rotating housing 2 and located at the other end of one of the rotating rollers 3. The output end of the first motor 15 passes through the other side of the rotating housing 2 and is coaxially connected to one of the rotating rollers 3.

[0059] The system starts with motor 15, whose output shaft drives one of the rotating rollers 3 to rotate. This rotation drives conveyor belt 4, which in turn drives another rotating roller 3. This rotation drives transmission wheel 13, which in turn drives belt 14. Belt 14 drives transmission wheel 12, which in turn drives cleaning brush 8. Conveyor belt 4 then moves several grid plates 5 upwards, allowing them to... The garbage in the ditch is carried out and conveyed upward on the conveyor belt 4 until it falls into the collection box 6. At the same time, the spacing between the bars of the grid plate 5 is 0.2-2mm, which can filter out larger impurities in the water as well as smaller particulate matter, fibrous materials and hair. Meanwhile, the rotating cleaning brush 8 can clean the surface of the conveyor belt 4. The transmission of the conveyor belt 4 can ensure that the conveyor belt 4 can be thoroughly cleaned. After the entire device is used, the surface of the conveyor belt 4 can be cleaned in time to ensure that no garbage remains on the surface of the conveyor belt 4 and thus no unpleasant odor is emitted.

[0060] This embodiment provides an internal flow type ultrafine bar screen machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the output shaft of motor 15 is rotatably connected to the rotating shell 2.

[0061] Among these measures, it is ensured that the output shaft of motor 15 can rotate normally within the rotating housing 2. Example 6

[0062] This embodiment provides an internal flow type ultrafine bar screen machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the periphery of the cleaning brush 8 is in contact with the conveyor belt 4, one end of the water pipe 9 is threadedly connected to the water pump 11, and the water pipe 9 is connected to the water outlet of the water pump 11.

[0063] In this process, it is ensured that the rotating cleaning brush 8 can clean the surface of the conveyor belt 4, that the structure of the water pipe 9 and the water pump 11 is stable, and that the water pump 11 can deliver the cleaning fluid into the water pipe 9. Example 7

[0064] This embodiment provides an internal flow type ultrafine bar screen machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the cross-section of the baffle 20 is triangular.

[0065] Among them, it is ensured that the baffle 20 can effectively block the garbage above the baffle 20.

[0066] It is worth noting that the spacing between the bars of the grating plate 5 is between 0.2 and 2 mm. This fine spacing allows it to filter out larger impurities in the water as well as smaller particulate matter, fibrous materials, and hair.

[0067] It is worth noting that the water inlet of the water pump 11 is connected to a loading box through a connecting pipe, and the loading box is filled with cleaning fluid. This ensures that the water pump 11 can draw out the cleaning fluid from the loading box through the connecting pipe and deliver it to the water pipe 9, and then spray it out from several nozzles 10 on the water pipe 9. The several nozzles 10 can evenly spray the cleaning fluid onto the surface of the conveyor belt 4.

[0068] Working principle: In use, the operator first fixes the fixed base 1 to the ditch using several expansion bolts. Then, the operator starts motor 2 19. The output shaft of motor 2 19 drives the worm gear 18 to rotate. Under the meshing action, the rotation of the worm gear 18 drives the worm wheel 17 to rotate within the rotating groove 16. The rotation of the worm wheel 17 drives the rotating shell 2 to rotate within the fixed base 1 until the baffle 20 on the rotating shell 2 falls to the bottom of the ditch. At this point, motor 2 19 is stopped, ensuring that the operator can adjust the tilt angle of the rotating shell 2 according to the different depths of the ditch, thus better cleaning the garbage in the ditch. The operation is simple. Then, motor 1 15 is started. The output shaft of motor 1 15 drives one of the rotating rollers 3 to rotate. The rotation of the moving roller 3 drives the conveyor belt 4 to rotate, and the conveyor belt 4 drives another rotating roller 3 to rotate. The rotation of one of the rotating rollers 3 drives the second transmission wheel 13 to rotate, and the rotation of the second transmission wheel 13 drives the belt 14 to rotate. The belt 14 drives the first transmission wheel 12 to rotate, and the rotation of the first transmission wheel 12 drives the cleaning brush 8 to rotate. The transmission of the conveyor belt 4 drives several grid plates 5 to move upward. The grid plates 5 can carry the garbage in the ditch out and transport it upward on the conveyor belt 4 until the garbage falls into the collection box 6. At the same time, the spacing between the grid bars of the grid plates 5 is 0.2-2mm, which can filter out larger impurities in the water as well as smaller particulate dirt, fibrous materials and hair.

[0069] After the entire device is in use, the operator can start motor 19. The output shaft of motor 19 drives worm gear 18 to rotate. Under the action of meshing, worm gear 18 rotates and drives worm wheel 17 to rotate in rotating groove 16. The rotation of worm wheel 17 will drive rotating housing 2 to rotate in fixed seat 1 until the baffle 20 at the bottom of rotating housing 2 rotates out of the water ditch. At this time, water pump 11 can be started. Water pump 11 can draw out the cleaning liquid in the loading box through the connecting pipe and transport it to water pipe 9. Then, it is sprayed out from several nozzles 10 on water pipe 9. Several nozzles 10 can evenly spray the cleaning liquid on the surface of conveyor belt 4. At the same time, the cleaning brush 8 rotates to clean the surface of conveyor belt 4. The transmission of conveyor belt 4 can ensure that conveyor belt 4 can be completely cleaned. This ensures that after the entire device is used, the surface of conveyor belt 4 can be cleaned in time to ensure that no garbage remains on the surface of conveyor belt 4 and thus no unpleasant odor is emitted.
