Description

Technical Field

[0001] The invention relates to the field of sludge treatment, and in particular to a sludge environmental protection treatment device. Background Art

[0002] Sludge is the product of sewage treatment. It is an extremely complex heterogeneous body composed of organic debris, bacterial cells, inorganic particles, colloids, etc. The main characteristics of sludge are high water content (up to 99% or more), high organic content, easy to decompose and stink, fine particles, low specific gravity, and colloidal liquid. Sludge needs to be dehydrated and dried during treatment to reduce odor and facilitate transportation by staff.

[0003] Chinese Patent: CN117566995B discloses a sludge filtering and drying treatment device, which relates to the technical field of sludge treatment, and comprises: a shell, end covers are installed at both ends of the shell, and an inner ring body is arranged inside the end cover; an inner cylinder, the inner cylinder is rotatably connected to the inner ring body on the end cover, a spiral conveying blade is arranged inside the inner cylinder, and both ends of the spiral conveying blade are rotatably connected to the end cover; a transmission assembly, the transmission assembly is installed on the end cover, and the transmission assembly is used to drive the inner cylinder and the spiral conveying blade to rotate.

[0045] The length direction of the two strip air inlet grooves 15 is the same as the conveying direction of the synchronous belt 2 and is located away from the feed port 13. The two strip air inlet grooves 15 are respectively located above and below the synchronous belt 2. When the sludge is processed, the staff puts the sludge into the processing box 1 through the feed port 13. At this time, the sludge is located between the arc guide plate and the adjacent vertical plate 11. A plurality of filter plates 51 are equidistantly arranged inside the strip frame 3. The plurality of strip frames 3 cooperate with the filter plates 51 to "block" the discharge port 121, which can not only prevent the sludge from falling directly to the bottom of the processing box 1, but also continuously The sludge entering the treatment box 1 is initially filtered; then, the sludge enters the corresponding strip frame 3, and as the synchronous belt 2 slowly moves, the vertical plate 11 near the arc-shaped guide plate can "scrape" the sludge on the strip frame 3, which can not only continuously process the sludge, but also quantify the sludge in the strip frame 3, thereby shortening the sludge processing time and improving the processing efficiency; then, the strip frame 3 with the sludge is moved between the two vertical plates 11, so that the sludge can be filtered for the second time to ensure the dehydration effect of the sludge; when the strip frame 3 moves to the upper strip air inlet groove 15, the drying mechanism The hot air is transported to the upper strip air inlet groove 15, and the multiple sealing plates 34 can block the strip air inlet groove 15. Subsequently, the hot air enters the ventilation groove 31 of the corresponding strip frame 3 through the air inlet hole 341 on the sealing plate 34 and continuously dries and dehydrates the sludge through the first drying holes 33 on the inner walls of both sides of the corresponding strip frame 3. In the drying and dehydration process, the multiple filter plates 51 can move back and forth in a wave shape with the entry of the hot air, and can shake the sludge placed thereon, thereby improving the dehydration effect of the sludge. With the transportation of the synchronous belt 2, the moving frame arranged on the synchronous belt 2 flips 180 degrees, Thereby, the dehydrated sludge can fall onto the conveyor belt 161. At this time, the movable frame moves to the strip air inlet groove 15 located below. With the cooperation of the drying mechanism 4, the flipped multiple filter plates 51 can move back and forth in a wave shape, thereby preventing the dehydrated sludge from adhering to the inside of the strip frame 3; and the strip frame 3 located below can contact the water after the primary filtration and the secondary filtration, thereby backwashing the filter plate 51 to avoid clogging of the filter holes 511 on the filter plate 51; the filtered water is discharged from the processing box 1 through the drain port 14 on the processing box 1, thereby facilitating continuous processing of the sludge.

[0046] See also Figures 10 to 12As shown, each group of filtering mechanisms 5 also includes a synchronous shaft 52; each filter plate 51 is provided with a guide rod 512 at the four corners of one side close to the synchronous belt 2, and each strip frame 3 is provided with a plurality of connecting plates 35 on the side close to the synchronous belt 2. The guide rod 512 passes through the corresponding connecting plate 35 and is provided with a limit plate 513. Each guide rod 512 is also sleeved with a return spring 514, and the return spring 514 is located between the corresponding connecting plate 35 and the corresponding limit plate 513; the synchronous shaft 52 is rotatably arranged inside the corresponding strip frame 3 and the length direction of the synchronous shaft 52 is the same as the length direction of the corresponding strip frame 3. The synchronous shaft 52 is located between the plurality of filter plates 51 and the plurality of connecting plates 35. The synchronous shaft 52 is staggered along the axial direction with a plurality of abutment blocks 521 for pushing the filter plates 51; two partition plates 311 are provided at the center of the inner wall at the bottom of each ventilation groove 31, and a winding wheel 522 is provided at one end of the synchronous shaft 52 extending into the corresponding ventilation groove 31. The winding wheel 522 is positioned at the bottom of the corresponding ventilation groove 31. Between the two partition plates 311, each synchronous shaft 52 is sleeved with a reset torsion spring 523, which is located between the corresponding reel 522 and the bottom inner wall of the corresponding vent groove 31. A pressure plate 312 is slidably sealed between the two partition plates 311, and a traction rope 524 is wound around the reel 522. The end of the traction rope 524 away from the reel 522 is connected to the pressure plate 312; two booster springs 313 are also arranged on the side of the pressure plate 312 away from the reel 522. 21; An exhaust groove 313 is provided at the bottom of each partition plate 311, and a sealing plate 314 is hinged in each exhaust groove 313. Each sealing plate 314 is connected to the corresponding pressure plate 312 through a buffer rope 3122. A limit block 3111 for limiting the position of the sealing plate 314 is provided on the away side of each partition plate 311, and pushing rods 3123 for limiting the sealing plate 314 are provided at both ends of one side of each pressure plate 312 close to the winding wheel 522.

[0047] With the cooperation of the return spring 514 and the return torsion spring 523, the multiple filter plates 51 can be arranged parallel to each other and contact the synchronization shaft 52; it can not only play a supporting role, but also ensure that the volume of sludge entering the strip frame 3 can be kept consistent, ensuring the subsequent drying effect; when the strip frame 3 moves to the strip air inlet groove 15, with the cooperation of the multiple sealing plates 34, the strip air inlet groove 15 can be blocked, so that the hot air can pass through the air inlet hole 341 on the sealing plate 34 and enter between the two partition plates 311. At this time, the exhaust groove 313 is blocked by the hinged blocking plate 314 The air inlet hole 341 on the sealing plate 34 is located on the side of the pressure plate 312 away from the pressure-boosting spring 3121. With the intermittent transmission of hot air, the pressure plate 312 can overcome the elastic force of the pressure-boosting spring 3121 and move in the direction away from the reel 522, so that the pressure plate 312 can drive the reel 522 to rotate through the traction rope 524, and the reel 522 overcomes the torsion of the return torsion spring 523 to rotate, so that the multiple contact blocks 521 staggered on the synchronous shaft 52 can contact the filter plates 51 in turn, so that the multiple filter plates 51 can be in The wave shape moves in the direction of the axis of the corresponding guide rod 512 in sequence, thereby shaking the sludge and loosening the sludge. As the pressure plate 312 continues to move, the corresponding blocking plate 314 is pulled by the buffer rope 3122 to rotate along its hinged position, thereby opening the exhaust slot 313. The pressurized hot air can quickly pass through the exhaust slot 313 into the extension slots 32 on both sides, and dry and dehydrate the shaking sludge through the multiple first drying holes 33 on the inner walls of both sides of the bar frame 3, thereby improving the drying and dehydration efficiency of the sludge. At this time, the reset torsion spring 523 and the booster spring 3 Under the action of the elastic force of 121, the pressure plate 312 can be quickly reset and the synchronous shaft 52 can be rotated again, so that the sludge is continuously shaken. At this time, the push rod 3123 arranged on the pressure plate 312 can contact the corresponding sealing plate 314, so that the sealing plate 314 can rotate along the hinge position and contact the corresponding limit block 3111, so that the sealing plate 314 can block the corresponding exhaust groove 313, ensuring that the subsequent pressure plate 312 can move under the transportation of hot air, so that when the hot air is introduced, the sludge can be continuously shaken, thereby ensuring the drying efficiency of the sludge.

[0048] It is particularly noted that the diverging side in the present application refers to a side that is away from each other.

[0049] See also Figures 10 to 12 As shown, each partition plate 311 is provided with an inclined clamping seat 3112 on the opposite sides thereof, and each blocking plate 314 is provided with a clamping block 3141 cooperating with the clamping seat 3112 .

[0050] By providing a clamping block 3141, when the buffer rope 3122 pulls the corresponding sealing plate 314 to move, the clamping block 3141 can contact the corresponding clamping seat 3112, so that the position of the corresponding sealing plate 314 is fixed, ensuring that the hot air between the pressure plate 312 and the two partition plates 311 is discharged as much as possible, so that the pressure plate 312 can resist the corresponding winding wheel 522, and with the cooperation of the boost spring 3121 and the return torsion spring 523, the pressure plate 312 moves toward the direction close to the winding wheel 522, so that the pushing rod 3123 set on the pressure plate 312 can contact the corresponding sealing plate 314, so that the clamping block 3141 is disengaged from the corresponding clamping seat 3112, so that the sealing plate 314 can re-block the exhaust groove 313, ensuring that the subsequent movement of the pressure plate 312 will not be affected.

[0051] It is particularly noted that the facing sides in the present application are the sides that are close to each other.

[0052] See also Figures 9 to 12 As shown, two resistance rods 315 are mirror-imaged on the inner walls at both ends of each ventilation groove 31 along the length direction, a water baffle plate 321 is slidably arranged in each extension groove 32, and a guide hole 322 for the resistance rod 315 to pass through is arranged on the water baffle plate 321, and the resistance rod 315 can be slidably arranged in the corresponding guide hole 322, and a compression spring 3151 is sleeved on each resistance rod 315, and the compression spring 3151 is located on the side of the corresponding water baffle plate 321 away from the partition plate 311.

[0053] In order to prevent moisture in the sludge from entering the extension groove 32 through the first drying hole 33 when the sludge fills the bar frame 3, a water baffle 321 is provided. When the sludge is filled, under the elastic force of the compression spring 3151, the water baffle 321 can be fitted into the corresponding extension groove 32, thereby blocking the multiple first drying holes 33. When the drying mechanism 4 is running, hot air enters between the water baffle 321 and the corresponding partition plate 311 through the exhaust groove 313 on the two partition plates 311. As the hot air is continuously transported, the hot air pressure between the water baffle 321 and the corresponding partition plate 311 increases, so that the water baffle 321 can overcome the elastic force of the corresponding compression spring 3151 and move, so that the pressurized hot air can enter the extension groove 32 more quickly, which can not only improve the drying effect of the sludge, but also blow out the sludge that has entered the first drying hole 33 to prevent it from entering the extension groove 32.

[0054] See also Figures 12 to 17As shown, a rectangular annular cavity 515 is arranged inside each filter plate 51, and a plurality of second drying holes 516 connected to the rectangular annular cavity 515 are arranged in a rectangular distribution on both sides of each filter plate 51 along the length direction, and a plurality of air outlet holes 323 are arranged equidistantly along the length direction on each extension groove 32, and each air outlet hole 323 is connected to the rectangular annular cavity 515 of the corresponding filter plate 51 through a connecting hose 324.

[0055] In order to further improve the drying efficiency of the sludge, a rectangular annular cavity 515 is arranged on the filter plate 51. When hot air is not introduced, the water baffle 321 can block the multiple air outlet holes 323 in the corresponding extension groove 32. When hot air is introduced, the hot air pushes the water baffle 321 to move, thereby opening the air outlet holes 323. At this time, when the multiple filter plates 51 in the same strip frame 3 move in a wave shape, the hot air can enter the rectangular annular cavity 515 along the connecting hose 324 and be discharged through the multiple second drying holes 516 on both sides of the filter plate 51, so that the hot air can dry and dehydrate the inside of the sludge, thereby improving the drying efficiency.

[0056] See also Fig.15 and Fig.16 As shown, the second drying hole 516 is arranged at an angle, and the axis of the second drying hole 516 is arranged at an acute angle to the side of the corresponding filter plate 51 close to the guide rod 512.

[0057] By means of the second drying hole 516 which is arranged at an angle, the hot air can separate from the sludge more quickly after coming into contact with the sludge, thereby avoiding moisture residue. When the multiple filter plates 51 are moved alternately, the hot air can blow to the bottom of the adjacent filter plates 51, so that the hot air can dry the sludge through the filter holes 511, thereby further improving the drying effect of the sludge.

[0058] See also Figure 1 , Figure 2 and Figure 5 As shown, the drying mechanism 4 includes a drying hood 41 and a hot air blower 42; the drying hood 41 is arranged on one side of the processing box 1 close to the strip-shaped air inlet groove 15, and the hot air blower 42 is arranged on the drying hood 41, and the output end of the hot air blower 42 extends into the interior of the drying hood 41.

[0059] A drying hood 41 is provided, the drying hood 41 is sealed and connected to the processing box 1, and the two strip-shaped air inlet grooves 15 are both located inside the drying hood 41. Hot air is intermittently transported inside the drying hood 41 through the hot air blower 42, so that the sludge can be continuously processed.

[0060] See also Figure 3 As shown, an inverted L-shaped separation plate 17 is also provided at the bottom of the processing box 1.

[0061] By providing an inverted L-shaped separation plate 17, not only can the water filtered from the sludge be separated from the dehydrated sludge, but also the sludge adhering to the surface of the strip frame 3 can be scraped off, thereby avoiding the sludge adhering to the surface of the strip frame 3, and the separation plate 17 cooperates with the separation plate 17 away from the arc-shaped mud guiding plate 12 to collect the hot air, so that the hot air can be blown again along the rectangular groove 16 to the sludge on the conveyor belt 161, thereby further improving the drying effect.

[0062] See also Figure 3 As shown, a vibrating rod 122 is further provided inside the processing box 1 , and the vibrating rod 122 is located at the discharge port 121 .

[0063] By providing a vibrating rod 122, the sludge can be vibrated, which not only allows it to enter the strip frame 3 more evenly, but also avoids sludge clogging. Furthermore, the vibrating rod 122 can also put the strip frame in a slightly vibrating state, which can improve the drying effect of the sludge.

[0064] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
