Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment, and in particular to sludge filter pressing and dehydration equipment. Background Art

[0002] With the acceleration of urbanization and the continuous development of industrial production, the output of sludge continues to increase. Sludge that has not been effectively treated has a high moisture content and a large volume, which is not only difficult to transport and dispose of, but also causes secondary pollution to the environment. Sludge dehydration is a key step in the sludge treatment process. Dehydration can reduce the moisture content of sludge and reduce the volume of sludge, making it easier to transport, dispose of and recycle it.

[0003] When the existing sludge dewatering device is in use, hard debris may be carried in the sludge, which may easily affect the operation of the device and cause damage to the device during the dewatering process through the filter press dewatering device.

[0004] For example, the authorization announcement number CN118047517B provides an environmentally friendly sludge dewatering equipment that prevents hard debris. By setting a discharge box, the sludge is drawn into the discharge box from the discharge channel formed by two partitions cooperating with the front and rear sides of the discharge box. The initial positions of the two partitions are aligned with the vertical section of the discharge rack. The spring in the compressed state cooperates with the T-bar to support the folding plate. The folding plate is initially located between the partition and the baffle to block the sludge. The through holes of the discharge rack filter larger-sized debris in the sludge. The driving mechanism drives the extrusion plate to slide between the front and rear sides of the discharge box, and the horizontal section of the extrusion plate slides between the partition and the baffle, and the blocking structure cancels the blocking. The sludge carrying hard debris between the extrusion plate, the opposite side of the baffle and the top of the discharge rack is squeezed, and the extrusion plate, the opposite side of the baffle and the discharge rack cooperate to form a dynamically shrinking extrusion space, and the debris with smaller hardness is squeezed out of the extrusion space, and the sludge flows out from the drainage holes of the extrusion plate or the through holes of the discharge rack. The larger hard debris remains in the extrusion space, and the driving component drives the adjacent baffles away from the extrusion plate. The hard debris falls between the side wall of the discharge box and the side wall of the vertical section of the discharge rack and is discharged from the discharge pipe, which has a pre-screening structure for hard debris and reduces the wear of subsequent processing equipment by hard debris.

[0005] It has a major disadvantage: in the process of pushing hard debris through one side of the extrusion plate, due to the high viscosity of the sludge, the hard debris is easy to adhere to one side of the extrusion plate, making it impossible to fall off; the hard debris attached to one side of the extrusion plate will re-enter the sludge, resulting in poor separation efficiency of sludge and hard debris. Summary of the invention

[0017] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages: First, the scraper is changed into a triangular prism shape, so that the hard debris attached to the side can slide down quickly, avoiding the hard debris attached to the side that cannot slide down quickly due to a small slope, causing it to re-enter the device and remain inside, which helps to reduce the accumulation of hard debris in the equipment and keep the equipment clean and running efficiently; and the discharged sludge is cut off by the interception plate, which can be easily transported; Secondly, through the expansion and contraction of the airbag, the sludge and hard debris in front of the moving plate are constantly pushed, and the hard debris blocking the mesh holes on the filter plate is pushed out multiple times to make it fall off, thereby increasing the speed at which the sludge falls below the filter plate and preventing the hard debris from getting stuck in the mesh holes on the filter plate, thereby improving the separation effect of the sludge and hard debris; and when the moving plate moves and the hard debris falls into the storage box, the expansion and deflation of the airbag pushes the hard debris to fall, thereby improving the collection effect; the expansion and deflation of the airbag can shake off the hard debris attached to its surface, thereby improving the cleaning effect of the hard debris; Thirdly, by increasing the number of airbags, the separation efficiency of hard debris and sludge can be improved, and the falling speed of sludge can be increased. When hard debris accumulates at one end, the airbag at that position is controlled to expand to resist the hard debris in front, so that the hard debris in front of the scraper is evenly dispersed, and the sludge falling speed at one end is reduced due to more hard debris accumulated at one end. The uniform dispersion of hard debris enables the scraper to push the hard debris more smoothly during movement, reducing the resistance caused by accumulation, thereby improving the overall processing efficiency. Moreover, when the hard debris falls and is collected, since the hard debris accumulated in front of the scraper is evenly distributed, the scraper can move a shorter distance, so that the accumulated hard debris falls completely, and the falling and collection speed of the hard debris is increased. Fourthly, the separation effect of hard debris and sludge is improved through the vibration of the elastic rope. The elastic rope drives the hard debris to turn over, which can further prevent the hard debris from clogging the mesh of the filter plate and improve the falling and separation speed of the sludge. At the same time, the falling of the hard debris and the resetting of the elastic rope will generate vibration, thereby further improving the falling and separation speed of the sludge; when the hard debris falls into the storage box, the elastic rope vibrates, which can increase the falling speed of the hard debris, thereby improving the separation speed of the device for the hard debris; and when the elastic rope is pulled, the hard debris and sludge above the elastic rope can be vibrated as a whole, thereby promoting the separation effect.

The guide plate 320 is fixed above the scraper 310. Both ends of the scraper plate 310 and the guide plate 320 in the length direction abut against the inner wall of the protective shell 210; The guide plate 320 has a rotation hole 321 and a guide hole 322 on its side, and both the rotation hole 321 and the guide hole 322 penetrate the guide plate 320; The two ends of the rotating rod 340 are respectively rotatably arranged on the side where the two baffles 220 are close to each other, and the two ends of the guide rod 350 are respectively fixed on the side where the two baffles 220 are close to each other.

[0024] During use, the motor 230 is started, driving the rotating rod 340 to rotate. During the rotation, the scraper 310 is driven to move to one side, and the sludge falls from the middle position between the two baffles 220 and is continuously poured between the two baffles 220. When the sludge falls on the scraper 310 and the guide plate 320, it slides down through the side of the guide plate 320.

When the hard debris hits the moving plate 230, the telescopic rod 240 drives the moving plate 230 to move, so that the moving plate 230 is away from the baffle 220 and the discharge barrel 250, so that the scraper 310 pushes the hard debris to fall into the storage box. 280, and discharged through the discharge pipe 281, then the motor 2 330 reverses to make the scraper 310 move to the other side, the telescopic rod 1 240 drives the moving plate 230 to reset, and after moving to the other side, the accumulated hard debris is also pushed and dropped into the storage box 280; the sludge after the first filtration enters the filter cylinder 150 through the discharge cylinder 250 and the discharge pipe 270, and the sludge entering the filter cylinder 150 is driven by the motor 140 to rotate the screw conveyor 160, and the sludge is transported to the filter cylinder 150. The sludge after squeezing can be discharged through one end of the filter cartridge 150; in the process of filtering and squeezing the sludge, one end of the filter cartridge 150 is intercepted by the interception plate 410, and when a large amount of sludge that has been pressed firmly hits one side of the interception plate 410, the telescopic rod 430 drives the interception plate 410 to rise, opens the outlet, and discharges the firmly pressed sludge; after a section of the sludge that has been pressed firmly is discharged, the interception plate 410 is reset to continue to press the internal sludge again, and the work is performed reciprocatingly.

[0025] Compared with the prior art, the scraper 310 is changed into a triangular prism shape, so that the hard debris attached to the side can slide down quickly, avoiding the hard debris attached to the side being unable to slide down quickly due to a small slope, causing it to re-enter and remain inside the device, which helps to reduce the accumulation of hard debris in the equipment and keep the equipment clean and efficient; and the discharged sludge is cut off by the interception plate 410, which can be easily transported.

[0026] Embodiment 2: When the embodiment 1 is in use, the efficiency of separating the sludge and the hard debris through the movement of the scraper 310 is poor, and a long time of residence is required for the sludge to be completely separated from the hard debris. Based on this, the solution of the embodiment 1 is improved, such as Fig.11 As shown: The screening assembly 300 also includes a mounting cavity 323, an air pump 360, an air inlet pipe 370 and an expansion group; The guide plate 320 has a mounting cavity 323 in it, and an air inlet pipe 370 on the guide plate 320, the air inlet pipe 370 is connected with the mounting cavity 323, and the air pump 360 is fixed in the mounting cavity 323; There are two expansion groups, corresponding to the two sides of the scraper 310 respectively, and the expansion group includes an air bag 380; The airbag 380 is fixed to the side of the scraper 310; The output end of the air pump 360 is in communication with the interior of the air bag 380; When the air pump 360 is working, the air bag 380 is expanded or retracted, and when the air bag 380 is expanded, it contacts the solid impurities in front.

[0027] During the movement of the scraper 310, the air pump 360 inflates and deflates the airbag 380, causing the airbag 380 to vibrate, constantly contacting the sludge and hard debris in front of the movement, and pushing and gathering the hard debris; when the moving plate 230 moves and causes the hard debris accumulated in front of the movement to fall into the storage box 280, the expansion and deflation of the airbag 380 can push the hard debris accumulated in front of it down, and the hard debris attached to the surface can be shaken off during the expansion and deflation of the airbag 380.

[0028] Through the expansion and contraction of the airbag 380, the sludge and hard debris located in front of the movement are constantly resisted, and the hard debris blocking the mesh holes on the filter plate 260 is pushed multiple times to make it detach, thereby increasing the speed at which the sludge falls to the bottom of the filter plate 260, and preventing the hard debris from being stuck in the mesh holes on the filter plate 260, resulting in the sludge being unable to fall, thereby improving the separation effect of the sludge and hard debris; and when the moving plate 230 moves and the hard debris falls into the storage box 280, the expansion and deflation of the airbag 380 pushes the hard debris to fall, thereby improving the collection effect; the expansion and deflation of the airbag 380 can shake off the hard debris attached to its surface, thereby improving the cleaning effect of the hard debris.

[0029] Embodiment 3: When the second embodiment is in use, the airbag 380 is expanded to increase the falling speed of the sludge, so that the sludge is separated from the hard debris, and the hard debris is prevented from clogging the mesh of the filter plate 260. However, when in use, the separation efficiency of the hard debris and the sludge is poor. Based on this, the scheme of the second embodiment is improved, such as Fig.12 As shown: The expansion group includes a plurality of air bags 380; The plurality of air bags 380 are evenly spaced along the length direction of the scraper 310; The number of the air pumps 360 is consistent with the number of the air bags 380 and corresponds one to one.

[0030] During use, when a large amount of hard debris accumulates at one end of the scraper 310, the airbag 380 at this position is controlled to expand. During the expansion process, the airbag 380 contacts the hard debris in front, so that the accumulated hard debris is dispersed, and the hard debris in front of the scraper 310 is evenly dispersed. When the movable plate 230 is opened to make the hard debris fall, the scraper 310 can move a shorter distance because the hard debris in front of the scraper 310 is evenly dispersed, so that the accumulated hard debris can fall completely.

[0031] By increasing the number of airbags 380, the separation efficiency of hard debris and sludge can be improved, and the falling speed of sludge can be increased. When hard debris accumulates at one end, the airbag 380 located at this position is controlled to expand to resist the hard debris located in the front, so that the hard debris located in front of the scraper 310 is evenly dispersed, thereby avoiding a large amount of hard debris accumulated at one end causing the sludge falling speed at one end to decrease; the uniform dispersion of hard debris enables the scraper 310 to push the hard debris more smoothly during movement, reduces the resistance caused by accumulation, and thus improves the overall processing efficiency; and when the hard debris falls and is collected, since the hard debris accumulated in front of the scraper 310 is evenly distributed, the scraper 310 can move a shorter distance, so that the accumulated hard debris falls completely, thereby improving the falling and collection speed of the hard debris.

[0032] Embodiment 4: When the embodiment 3 is in use, the airbag 380 at a single position is controlled to expand, so that the hard debris in front of the scraper 310 can be evenly distributed, thereby improving the separation efficiency of the hard debris and the sludge. However, when in use, the device can be further improved to improve the separation efficiency of the hard debris and the sludge. Based on this, the solution of the embodiment 3 is improved, such as Figure 13-Figure 19 As shown: There is a gap between the multiple air bags 380 located on the same side of the scraper 310; The screening assembly 300 further includes a wire-passing hole 311; The scraper 310 has a wire hole 311 on the side thereof, and the wire hole 311 passes through the scraper 310; The number of the wire holes 311 is consistent with the number of intervals between the airbags 380 on the same side, and they correspond one to one. The wire holes 311 are located between the intervals of two adjacent airbags 380. It also includes an auxiliary component 500, which includes a deformation group, an elastic rope 520 and an iron ball 530; There are two deformation groups, corresponding to the two sides of the scraper 310 respectively. The deformation groups include electromagnets 510, and the electromagnets 510 are fixed on the sides of the scraper 310. A single deformation group includes multiple electromagnets 510, and the multiple electromagnets 510 are evenly spaced along the length direction of the scraper 310. The number of the elastic ropes 520 is consistent with the number of the wire holes 311, and they correspond one to one. The elastic ropes 520 are slidably arranged in the wire holes 311. The two ends of the elastic ropes 520 are respectively fixed to the sides of the two moving plates 230 that are close to each other, and the elastic ropes 520 are fixed to the lower ends of the moving plates 230. An iron ball 530 is fixed inside the elastic rope 520, and there are a plurality of iron balls 530, which are evenly spaced along the length direction of the elastic rope 520; When the electromagnet 510 is turned on, it absorbs the iron ball 530 in the elastic rope 520, causing the elastic rope 520 to deform.

[0033] During the movement of the scraper 310, the electromagnet 510 in front of the movement is intermittently energized. When the electromagnet 510 is energized, the iron ball 530 in the nearby elastic rope 520 is attracted, so that the elastic rope 520 bounces up. During the bouncing process, the hard debris at the bottom is turned up, and the hard debris blocking the mesh of the filter plate 260 can be turned up. The turned up hard debris will then fall down by gravity, causing the filter plate 260 to vibrate as a whole, thereby increasing the falling speed of the sludge and removing the hard debris on the surface of the hard debris. The sludge is shaken off; and when the electromagnet 510 is powered off, the elastic rope 520 is reset, and the hard debris and the filter plate 260 are knocked to generate vibration; when the elastic rope 520 is stretched, the hard debris on the surface of the elastic rope 520 located behind the scraper 310 can be vibrated; in the process of the scraper 310 moving and the airbag 380 expanding to make the debris fall off, the electromagnets 510 at different positions are intermittently powered on, so that the elastic rope 520 vibrates and the hard debris on the surface is shaken off.

[0034] The vibration of the elastic rope 520 can improve the separation effect of hard debris and sludge. The elastic rope 520 drives the hard debris to turn over, which can further prevent the hard debris from clogging the mesh of the filter plate 260 and improve the falling and separation speed of the sludge. At the same time, the falling of the hard debris and the resetting of the elastic rope 520 will generate vibration, thereby further improving the falling and separation speed of the sludge; when the hard debris falls into the storage box 280, the elastic rope 520 vibrates, which can increase the falling speed of the hard debris, thereby improving the separation speed of the device for the hard debris; and when the elastic rope 520 is pulled, the hard debris and sludge above the elastic rope 520 can vibrate as a whole, thereby promoting the separation effect.
