Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and specifically relates to an anti-blocking drainage device for water conservancy project construction. Background Art

[0002] During the construction of water conservancy projects, it is often necessary to excavate the foundation pit. After excavation, it is necessary to drain the accumulated water in the foundation pit to prevent the accumulated water from affecting the construction. When draining the foundation pit, the usual method is to connect a centrifugal water pump to a drainage pipe, and then tie the centrifugal water pump with a rope and slowly lower the centrifugal water pump connected with the drainage pipe into the foundation pit to a certain position below the water surface in the foundation pit.

[0003] During the construction of water conservancy projects, due to the relatively large amount of sediment and small stones in the working environment of the drainage device, the filter screen of the water pump becomes blocked. Usually, it is necessary to manually remove the blockage of the water pump before continuing to pump water. To solve the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, an anti-blocking drainage device for water conservancy project construction of the present invention includes a housing, and the housing further includes a support one fixedly connected to the bottom of the housing. The bottom of the support one is fixedly connected to a base. A rotating housing is fixedly connected to the inner wall of the housing, and a partition one is fixedly connected to the inner wall of the housing.

[0005] A pumping mechanism, the pumping mechanism includes a motor providing power, a rotating shaft, a screw conveyor, and a sewage pump for connecting the motor to pump water, and an anti-blocking mechanism for preventing pumping blockage.

[0006] The top of the housing is fixedly connected to the bottom of the motor, the rotating part of the motor is fixedly connected to the outer wall of the rotating shaft, the outer wall of the rotating shaft is rotationally connected to the inner wall of the screw conveyor, and a sewage pump is fixedly connected to the inside of the housing.

[0007] Preferably, the anti-blocking mechanism includes a filter screen cage fixedly connected to the outer wall of the base, and a support two is fixedly connected to the outer wall of the base. The inner wall of the filter screen cage is fixedly connected to the outer wall of the support two.

[0008] Preferably, the anti-blocking mechanism includes a filter screen cage fixedly connected to the outer wall of the base, and a support two is fixedly connected to the outer wall of the base.

[0009] Preferably, the inner wall of the filter cage is fixedly connected to the outer wall of the second bracket, a plurality of filter holes are opened on the outer wall of the filter cage, a plurality of hydraulic rods are fixedly connected to the outer wall of the second bracket, and the rotating plate is rotatably connected to the extrusion plate and rotates at the top rod, so that the top rod and the partial structure of the rapid flow box are tightly attached to the inside of the filter cage, and when water flows out of the water-exciting hole, one end is held tightly by the extrusion plate, so that the water flows to the other half and the front, and at the same time, when the water-pushing plate moves forward, the other side will drive the reset flow isolation plate forward and thus be close to the filter cage. At this time, the left and right sides of the water-exciting hole are temporarily closed, so that the water ejected from the water-exciting hole flows to the front, making the water flow forward more forcefully, avoiding the water flow generated by the above-mentioned components being affected by the suction of the machine itself and losing the effect that it should have produced, so that the ejected water flows out of the machine and brings out the blockage.

[0010] Preferably, a plurality of hydraulic rods are fixedly connected to outer walls with a push rod, and one end of the hydraulic rod away from the push rod is fixedly connected to a reset flow partition.

[0011] Preferably, a rapid flow box is fixedly connected to the inner wall of the filter cage, a plurality of water-spraying holes are opened on the outer wall of the rapid flow box, the outer wall of the reset flow isolation plate is fitted and connected to the inner wall of the filter cage, and the outer wall of the top rod is fitted and connected to the inner wall of the filter cage.

[0012] Preferably, a connecting bracket 1 is fixedly connected to the outer wall of the reset flow partition plate, and a water pushing plate is fixedly connected to the end of the connecting bracket 1 away from the reset flow partition plate. The force of the squeezing plate rotating to squeeze the filter cage to bulge, when the inner wall of the filter cage bulges and rotates to the top rod, the top rod will push the hydraulic rod fixedly connected at the rear end, so that the other end of the hydraulic rod drives the water pushing plate at the inner wall of the rapids box forward. Because the front end of the rapids box is set as an extrudable waterproof soft rubber bag, when the squeezing plate presses against the filter cage, one end of the rapids box is forced to fit on the filter On the cage, when the water pushing plate pushes, because the interior of the rapids box is large and the water-jetting hole is small, and at the same time the water pushing plate fits tightly against the inner wall of the rapids box, the water in the rapids box is jetted outward from the water-jetting hole, and at the same time the reset flow isolation plate will be driven by the hydraulic rod with its front end close to the inner wall of the filter cage, so that the water flow generated by the above components is dispersed to the minimum extent, and flows to the outside of the equipment along the outer wall of the reset flow isolation plate, and the small stones and soil that fall off the filter holes on the filter cage flow out to avoid a large amount of blockages entering the internal drainage mechanism of the equipment.

[0013] Preferably, the outer wall of the water pushing plate is slidably connected to the inner wall of the rapids box. A number of return ports are provided on the outer wall of the water pushing plate, and a number of return plug plates are rotatably connected to the outer wall of the water pushing plate. When the filter cage rotates one circle, it presses against the reset baffle, causing the reset baffle to move backward, thereby driving the water pushing plate to move backward. The water pushing plate is provided with return ports. When moving backward, the return plug plates will be pushed open backward under the action of water flow, preventing negative pressure from being generated inside the rapids box and losing the original effect. When the water pushing plate pushes forward, the outer periphery of the return plug plate is one circle larger than the return port, so that the return port is blocked under the drive of water flow, thereby providing sufficient thrust. When the reset baffle moves backward, the ejector rod moves forward and presses against the filter cage under the transmission of the hydraulic rod, thereby achieving the reset effect. Repeating the above process, the effect of continuous water flow flowing out is achieved, and the filter holes of the filter cage are prevented from being blocked, thereby affecting the drainage effect.

[0014] Preferably, a rotating plate is fixedly connected to the bottom of the auger. The outer wall of the rotating plate is meshed with the outer wall of the first partition plate. An extrusion plate is fixedly connected to the inner wall of the rotating plate. A return groove is provided on the inner wall of the rotating plate. An arc-shaped outer shell is fixedly connected to the outer wall of the rotating plate. An arc-shaped partition plate is fixedly connected to the inner wall of the arc-shaped outer shell. A water pumping mechanism and an anti-blocking mechanism are provided inside the device. During operation, ensure that the top motor is in working condition, place the bottom of the device in the drainage ditch or drainage well at the construction site, and start the device by connecting the pipeline. The filter cage fixedly connected to the device base will filter out sediment and impurities, which is also the place most likely to be blocked. The force of driving the rotating shaft to rotate by the motor drives the bottom rotating plate to rotate. The rotating plate is rotatably connected to the top of the filter cage. When the rotating plate rotates, the extrusion plate fixedly connected to the rotating plate will squeeze the filter cage, causing the filter cage to sink. At the same time, because the filter cage is made of stainless steel and has toughness, when it rotates away from one side of the filter cage, the filter cage will rebound and reset under the action of its own toughness. At the same time, during this process, the mesh holes on the filter cage will be deformed on a large scale and vibrate during reset, causing the small stones and silt originally stuck in the filter holes to loosen and fall off.

[0015] Preferably, a drainage groove is provided on the inner wall of the arc-shaped housing, and an outer opening is provided on the outer wall of the drainage groove. A drain pipe is fixedly connected to the outer wall of the sewage pump, and the outer wall of the drain pipe is fixedly connected to the inner wall of the housing. A scraper is fixedly connected to the inner wall of the rotating plate. Using the water flow generated by the above-mentioned water jet holes, when the water flow generated by the water jet holes discharges outward, the rotating plate is in a rotating state. The water flow discharging outward carries the blockage, and the impurities scraped by the scraper will enter the return groove. When the rotating plate rotates, water will continuously enter through the outer opening, and the water flow will flow downward through the arc-shaped plate of the arc-shaped partition to generate a rotating suction force similar to that of a turbine. When the water flow entering through the return groove carries the blockage, under the action of the rotating force, it enters the interior of the arc-shaped housing, and through the setting of the arc-shaped partition, it flows downward from the drainage groove to below the base bottom plate, driving the blockage away from the water suction range of the equipment, avoiding the situation where the discharged blockage directly floats around the equipment and is re-absorbed into the machine by the equipment.

[0016] The present invention has the following beneficial effects:

[0017] (1) The present invention proposes the following solutions for the problem of drainage blockage. A water pumping mechanism and an anti-blocking mechanism are provided inside the equipment. Before working, ensure that the top motor is in working condition, place the bottom of the equipment in the drainage ditch at the engineering construction site, and start the equipment in the drainage well and connect the pipeline to start working. The filter cage fixedly connected to the equipment base will filter sediment impurities, which is also the place most likely to be blocked. Through the force of the motor driving the rotating shaft to rotate, the bottom low rotating plate is driven to rotate. The rotating plate is rotatably connected to the top of the filter cage. When the rotating plate rotates, the pressing plate fixedly connected to the rotating plate will press the filter cage, causing the filter cage to sink in. At the same time, because the filter cage is made of stainless steel and has toughness, when it rotates away from one side of the filter cage, the filter cage will rebound and reset under the action of its own toughness. At the same time, during this process, the mesh holes on the filter cage will deform and generate vibrations when reset, loosening and falling off the small stones and silt originally stuck in the filter holes; when the pressing plate rotates and presses against the filter cage, it will cause the filter cage to bulge towards the inner wall. Through the force of the pressing plate rotating and pressing the filter cage to bulge, when the inner wall of the filter cage bulges and rotates to the ejector rod, the ejector rod will push the hydraulic rod fixedly connected to the rear end, so that the other end of the hydraulic rod drives the water pushing plate at the inner wall of the water jet box to move forward. Because the front end of the water jet box is provided with a squeezable waterproof soft rubber bag, when the pressing plate abuts against the filter cage, it forces one end of the water jet box to fit on the filter cage. When the water pushing plate pushes, because the interior of the water jet box is large and the water jet holes are small, and at the same time the water pushing plate is closely attached to the inner wall of the water jet box, the water flow in the water jet box is ejected outward from the water jet holes, causing the blockage loosened and fallen off on the filter cage to flow outwards, avoiding the risk that the blockage falls down and enters the interior of the machine, causing the machine to be blocked.

[0018] (2) The present invention utilizes the ductility of the above-mentioned filter cage. When the water flow is ejected outward from the rapid flow box, the connecting bracket 1 will also drive the reset baffle plate to move forward simultaneously. When the water flow is ejected, the rotating plate is rotationally connected to the extrusion plate and rotates at the ejector rod, causing the ejector rod and a part of the structure of the rapid flow box to closely adhere to the inner part of the filter cage. When the water flow is ejected from the water jet holes, one end is blocked and pressed tightly by the extrusion plate, so that the water flow is ejected to the other half and directly forward. At the same time, when the water pushing plate moves forward on the other side, it will drive the reset baffle plate forward to closely adhere to the filter cage. At this time, the left and right sides of the water jet holes are temporarily blocked, so that the water flow ejected from the water jet holes flows out directly forward, making the water flow more powerful forward, avoiding the water flow generated by the above components being affected by the suction force of the machine itself and losing the original effect, and enabling the ejected water flow to eject the blocked objects outside the machine.

[0019] (3) The present invention utilizes the characteristic that the above-mentioned extrusion plate rotates around the filter cage. When the filter cage rotates one circle, it presses against the reset baffle plate, causing the reset baffle plate to move backward, thereby driving the water pushing plate to move backward. There is a return port on the water pushing plate. When moving backward, the return plug plate will be pushed backward by the water flow, avoiding creating negative pressure inside the rapid flow box and losing the original effect. When the water pushing plate pushes forward, the outer periphery of the return plug plate is one circle larger than the return port, so that it blocks the return port under the drive of the water flow, thereby providing sufficient thrust. When the reset baffle plate moves backward, the ejector rod moves forward under the transmission of the hydraulic rod and closely adheres to the filter cage, thereby achieving the reset effect. Repeating the above process, the effect of continuous water flow flowing outward is achieved, avoiding the blockage of the filter holes of the filter cage and affecting the drainage effect.

[0020] (4) The present invention utilizes the water flow generated by the above-mentioned water jet holes. When the water flow generated by the water jet holes is discharged outward, the rotating plate is in a rotating state. The water flow discharging outward carries the blocked objects, and the impurities scraped by the scraper will enter the return groove. When the rotating plate rotates, water will continuously enter from the outer port. The water flow generates a rotating suction similar to a turbine through the downward flow of the arc-shaped plate of the arc-shaped partition. When the water flow entering through the return groove carries the blocked objects, under the action of the rotating force, it enters the interior of the arc-shaped housing, and through the setting of the arc-shaped partition, it flows downward and flows out from the diversion groove under the base bottom plate, driving the blocked objects away from the water absorption range of the equipment, avoiding the situation where the discharged blocked objects directly float around the equipment and are reabsorbed by the equipment.

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 embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] A pumping mechanism 2, the pumping mechanism 2 includes a motor 21 providing power, a rotating shaft 22, a screw conveyor 23, and a sewage pump 24 for connecting the motor 21 to pump water, and an anti-blocking mechanism 3 for preventing pumping blockage;

[0037] The top of the housing 1 is fixedly connected to the bottom of the motor 21, the rotating part of the motor 21 is fixedly connected to the outer wall of the rotating shaft 22, the outer wall of the rotating shaft 22 is rotatably connected to the inner wall of the screw conveyor 23, and a sewage pump 24 is fixedly connected inside the housing 1.

[0038] The anti-blocking mechanism 3 includes a filter cage 31 fixedly connected to the outer wall of the base 12, a second support 32 is fixedly connected to the outer wall of the base 12, and the inner wall of the filter cage 31 is fixedly connected to the outer wall of the second support 32.

[0039] The anti-blocking mechanism 3 includes a filter cage 31 fixedly connected to the outer wall of the base 12, and a second support 32 is fixedly connected to the outer wall of the base 12.

[0040] The inner wall of the filter cage 31 is fixedly connected to the outer wall of the second support 32, a plurality of filter holes 33 are formed in the outer wall of the filter cage 31, and a plurality of hydraulic rods 34 are fixedly connected to the outer wall of the second support 32.

[0041] A top rod 35 is fixedly connected to the outer wall of a plurality of hydraulic rods 34, and a reset partition plate 36 is fixedly connected to the end of the hydraulic rod 34 away from the top rod 35.

[0042] A surge tank 37 is fixedly connected to the inner wall of the filter cage 31. A number of water jet holes 38 are provided on the outer wall of the surge tank 37. The outer wall of the reset baffle 36 is in fitting connection with the inner wall of the filter cage 31, and the outer wall of the ejector rod 35 is in fitting connection with the inner wall of the filter cage 31. When the surge tank 37 ejects water outward, the connecting bracket one 41 will also drive the reset baffle 36 to move forward at the same time. When the water is ejected, the rotating plate 51 is rotatably connected to the pressing plate 52 and rotates at the ejector rod 35, so that part of the structure of the ejector rod 35 and the surge tank 37 closely adheres to the inside of the filter cage 31. When the water jet holes 38 eject water, one end is blocked and pressed tightly by the pressing plate 52, so that the water is ejected to the other half and straight ahead. At the same time, when the water pushing plate 42 moves forward on the other side, it will drive the reset baffle 36 forward to closely adhere to the filter cage 31. At this time, the left and right sides of the water jet holes 38 are temporarily blocked, so that the water ejected from the water jet holes 38 flows out straight ahead, making the water flow forward more powerfully, avoiding the water flow generated by the above components being affected by the suction of the machine itself and losing the original effect, and making the ejected water flow out of the machine to bring out the blockage.

[0043] Embodiment 2. Please refer to Figure 5 - Figure 10 In this invention, a water conservancy project construction anti-blocking drainage device is provided. On the basis of Embodiment 1, a connecting bracket one 41 is fixedly connected to the outer wall of the reset baffle 36, and a water pushing plate 42 is fixedly connected to the end of the connecting bracket one 41 away from the reset baffle 36.

[0044] The outer wall of the water pushing plate 42 is slidably connected to the inner wall of the surge tank 37. A number of return ports 43 are provided on the outer wall of the water pushing plate 42, and a number of return plug plates 44 are rotatably connected to the outer wall of the water pushing plate 42. When the inner wall of the filter cage 31 bulges and rotates to the ejector rod 35, the ejector rod 35 will push the hydraulic rod 34 fixedly connected to the rear end, so that the other end of the hydraulic rod 34 drives the water pushing plate 42 on the inner wall of the surge tank 37 to move forward. Because the front end of the surge tank 37 is provided with a squeezable waterproof soft rubber bag, when the pressing plate 52 abuts against the filter cage 31, it forces one end of the surge tank 37 to fit on the filter cage 31. When the water pushing plate 42 is pushed, because the inside of the surge tank 37 is large and the water jet holes 38 are small, and at the same time the water pushing plate 42 is closely attached to the inner wall of the surge tank 37, the water in the surge tank 37 is ejected outward from the water jet holes 38, causing the loosened and fallen blockages on the filter cage to flow out, avoiding the blockages from falling into the machine interior and causing the risk of machine blockage.

[0045] A rotating plate 51 is fixedly connected to the bottom of the auger 23, and the outer wall of the rotating plate 51 is meshed with the outer wall of the partition 14, and an extrusion plate 52 is fixedly connected to the inner wall of the rotating plate 51. A reflux groove 53 is opened on the inner wall of the rotating plate 51, and an arc-shaped shell 54 is fixedly connected to the outer wall of the rotating plate 51, and an arc-shaped partition 55 is fixedly connected to the inner wall of the arc-shaped shell 54. A pumping mechanism 2 and an anti-blocking mechanism 3 are arranged inside the device. When working, ensure that the top motor is in a working state, place the bottom of the device in the drainage ditch of the construction site, and open the device in the drainage well to connect the pipeline to start working. The filter cage 31 fixedly connected to the base 12 of the device will filter out mud and impurities, and it is also the place that is most likely to be blocked. The motor 21 drives the rotating shaft 22 to rotate The force drives the bottom low rotating plate 51 to rotate, and the rotating plate 51 is rotatably connected to the top of the filter cage 31. When the rotating plate 51 rotates, the squeezing plate 52 fixedly connected to the rotating plate 51 will squeeze the filter cage 31 to make the filter cage 31 concave. At the same time, because the filter cage 31 is made of stainless steel and has toughness, when it rotates away from one side of the filter cage 31, the filter cage 31 will rebound and reset under the action of its own toughness. At the same time, in this process, the mesh on the filter cage 31 will be greatly deformed and vibrate when it is reset, so that the pebbles and silt originally stuck in the filter holes 33 are loosened and fall off. When the squeezing plate 52 rotates in contact with the filter cage 31, the filter cage 31 will bulge toward the inner wall, and the squeezing plate 52 rotates to squeeze the filter cage 31 to bulge.

[0046] A drainage groove 56 is provided on the inner wall of the arc-shaped housing 54, and an outer opening 57 is provided on the outer wall of the drainage groove 56. A drainage pipe 61 is fixedly connected to the outer wall of the sewage pump 24, and the outer wall of the drainage pipe 61 is fixedly connected to the inner wall of the housing 1. A scraper 58 is fixedly connected to the inner wall of the rotating plate 51. By utilizing the characteristic that the extrusion plate 52 rotates around the filter cage 31, when the filter cage 31 rotates one circle, it supports the reset flow isolation plate 36, causing the reset flow isolation plate 36 to move backward, thereby driving the water pusher 42 to move backward. A reflux port 43 is provided on the water pusher 42. When moving backward, the reflux plug The plate 44 will be pushed backwards under the action of the water flow to avoid negative pressure inside the rapids box 37, thereby losing the original effect. When the water-pushing plate 42 pushes forward, the outer periphery of the return plug plate 44 is larger than the return port 43, so that the return port 43 is blocked under the drive of the water flow, thereby increasing sufficient thrust. When the reset flow isolation plate 36 moves backwards, the push rod 35 moves forward and close to the filter cage 31 under the transmission of the hydraulic rod 34, thereby achieving the reset effect. Repeat the above process to achieve the effect of continuous water flow outward, avoiding clogging of the filter holes 33 of the filter cage 31 and affecting the drainage effect.

[0047] A specific application of this embodiment is as follows: A pumping mechanism 2 and an anti-blocking mechanism 3 are arranged inside the device. Before working, ensure that the top motor is in working condition, place the bottom of the device in the drainage ditch at the engineering construction site, and start working by connecting the pipeline after turning on the device in the drainage well. The filter cage 31 fixedly connected to the device base 12 will filter out sediment impurities, which is also the place most likely to be blocked. By the force of the motor 21 driving the rotation of the rotating shaft 22, the bottom low rotating plate 51 is driven to rotate. The rotating plate 51 is rotatably connected to the top of the filter cage 31. When the rotating plate 51 rotates, the pressing plate 52 fixedly connected to the rotating plate 51 will press the filter cage 31, causing the filter cage 31 to sink in. At the same time, because the filter cage 31 is made of stainless steel and has toughness, when it rotates away from one side of the filter cage 31, the filter cage 31 will rebound and reset under the action of its own toughness. At the same time, during this process, the mesh holes on the filter cage 31 will be deformed on a large scale and generate vibrations during reset, causing the small stones and silt originally stuck in the filter holes 33 to loosen and fall off, and then scraping them off through the scraper 58.

[0048] Utilizing the ductility of the above-mentioned filter cage 31, when the pressing plate 52 rotates in contact with the filter cage 31, it will cause the filter cage 31 to bulge towards the inner wall. By the force of the pressing plate 52 rotating and pressing the filter cage 31 to bulge, when the inner wall of the filter cage 31 bulges and rotates to the ejector rod 35, the ejector rod 35 will push the hydraulic rod 34 fixedly connected to the rear end, so that the other end of the hydraulic rod 34 drives the water-pushing plate 42 at the inner wall of the rapid-flow tank 37 to move forward. Because the front end of the rapid-flow tank 37 is provided with a squeezable waterproof soft rubber bag, when the pressing plate 52 abuts against the filter cage 31, it forces one end of the rapid-flow tank 37 to fit on the filter cage 31. When the water-pushing plate 42 pushes, because the inside of the rapid-flow tank 37 is large and the water jet holes 38 are small, and at the same time the water-pushing plate 42 is closely attached to the inner wall of the rapid-flow tank 37, the water flow in the rapid-flow tank 37 is ejected outward from the water jet holes 38. At the same time, the reset baffle 36 will also be driven by the hydraulic rod 34 to make the front end close to the inner wall of the filter cage 31, minimizing the dispersion of the water flow generated by the above components, flowing outward along the outer wall of the reset baffle 36 to the outside of the device, and flowing out the small stones and soil falling off the filter holes 33 on the filter cage 31 to prevent a large amount of blockage from entering the internal drainage mechanism of the device.

[0049] Using the characteristic that the above-mentioned pressing plate 52 rotates around the filter cage 31, when the filter cage 31 rotates one circle, it presses against the reset baffle 36, causing the reset baffle 36 to move backward, thereby driving the water pushing plate 42 to move backward. A return port 43 is provided on the water pushing plate 42. When moving backward, the return plug plate 44 will be pushed open backward under the action of water flow, avoiding creating negative pressure inside the rapids box 37 and thus losing the original effect. When the water pushing plate 42 pushes forward, the outer periphery of the return plug plate 44 is one circle larger than the return port 43, so as to block the return port 43 under the drive of water flow, thereby providing sufficient thrust. When the reset baffle 36 moves backward, under the transmission of the hydraulic rod 34, the ejector rod 35 moves forward and presses tightly against the filter cage 31, thereby achieving the reset effect. Repeating the above process, the effect of continuous water flow flowing outward is achieved, avoiding the blockage of the filter holes 33 of the filter cage 31 and thus affecting the drainage effect.

[0050] Using the water flow generated by the above-mentioned water jet holes 38, when the water flow generated by the water jet holes 38 discharges outward, the rotating plate 51 is in a rotating state. The water flow discharging outward carries the blockage, and the impurities scraped by the scraper 58 will enter the return groove 53. When the rotating plate 51 rotates, water will continuously enter the outer port 57. The water flow generates a rotating suction force similar to that of a turbine through the downward flow of the arc-shaped plate of the arc-shaped partition 55. When the water flow entering through the return groove 53 carries the blockage, under the action of the rotating force, it enters the interior of the arc-shaped housing 54, and through the setting of the arc-shaped partition 55, it rotates downward and flows from the guiding groove 56 to under the bottom plate of the base 12, driving the blockage away from the water absorption range of the device, avoiding the situation where the discharged blockage directly floats around the device and is reabsorbed into the machine by the device.
