Description

Technical Field

[0001] The present invention relates to the technical field of sludge dewatering and solidification, and more specifically, to a municipal environmental sludge dewatering and solidification device and method. Background Art

[0002] Sludge refers to fine-grained soil deposited in static water and slow-flowing water environments and containing organic matter. It generally exists in river channels. Excessive accumulation of sludge in river channels will cause the riverbed to become shallower and the water storage capacity to decrease, which will deteriorate the water quality of the river channel and damage the water quality environment. Therefore, when there is too much sludge accumulated in the riverbed, a sludge dewatering and solidification device is needed to treat it.

[0003] When the existing sludge is dewatered and then solidified, solidifying powder needs to be added to the sludge. However, the general inlet circle of the solidifying powder is relatively large, and when the solidifying powder is fed, it is easy to overflow into the air, resulting in waste. And in the existing technology, when dewatering sludge, it is filtered through a sieve, but the fluidity of the sludge is relatively poor during the filtration of the sieve, which affects the dewatering effect. For this reason, we propose a sludge dewatering and solidification device. Summary of the Invention

[0014] According to another aspect of the present invention, a method for dewatering and solidifying sludge in the municipal environment is provided.

[0015] It includes the following steps:

[0016] Put the sludge into the sludge feeding funnel and enter the lower semi-circular groove;

[0017] By driving the driving part to operate, the driving part drives the sludge driving wheel to rotate under the drive of the auxiliary power part. The sludge driving wheel will drive the incoming sludge to roll, causing the sludge to tumble onto the blanking table and slide down the inclined surface of the blanking table onto the side fault pushing columns;

[0018] Drive multiple fault pushing columns to slide up and down together through the driving part. When the fault pushing columns push upwards, the inclination angle of the top surface is parallel to the top surface of the adjacent fixed ladder plate on the side, prompting the fault pushing columns to push the falling sludge upwards. Under the upward push, the sewage contained in the sludge flows down through the water outlet channel and enters the inclined filter plate below to achieve re-filtration;

[0019] The overflowing sewage is filtered multiple times through the first activated carbon filter plate below;

[0020] The sewage after multiple filtrations is discharged from the sewage outlet;

[0021] The filtered sludge is pushed forward section by section through the fault push column. After multiple pushes, the contained sewage is filtered out, and the remaining sludge is pushed to the first discharge inclined opening, enters the first disc, and is conveyed downward through the upper through hole in the middle.

[0022] When the first driving motor operates, the first motor drives the middle gear, which in turn drives the side gear to rotate. The side gear will drive the cooperating threaded lifting rod, causing the threaded lifting rod to perform a lifting motion.

[0023] The threaded lifting rod drives the second disc to move up and down reciprocally. The distance between the second disc and the first disc will constantly change. The sludge entering through the changing trajectory of the distance between them is compressed and stretched, better achieving the effect of sludge extraction.

[0024] The sludge inside the left cavity is pressed under the compression motion generated by the compression component and finally discharged from the sludge outlet.

[0025] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0026] 1. In this device, a sludge pushing part is provided below the sludge feeding channel. During the operation of the sludge pushing part, the entering sludge and the contained sewage are lifted and rolled together. During the rolling and flipping, they are conveyed to one side, preventing the entering sludge from clogging and accumulating at the feeding channel. Then, along with the sludge pushing part on one side, the sludge and sewage are pushed step by step in a fault manner upwards. During the pushing process, the contained sewage will drain out, and the water will flow downward along the water outlet channel, while the remaining sludge is pushed step by step into the left cavity by the fault push column and is compressed by the compression component in the left cavity, effectively achieving the dehydration effect of the sludge.

[0027] 2. When the orifice of the solidifying powder feeding port is relatively large, it is adjusted by the metering mechanism below, thereby realizing the adjustment of the contact surface at the orifice diameter. When the diameter of the orifice changes during the entry of the solidifying powder, the entering solidifying powder is rolled into the lower part under the limitation of the spiral limiting wheel, thus being not likely to overflow into the air.

[0028] 3. When the compression component performs a compression motion, it will drive the entering sludge to be compressed, improving the treatment of the sludge, facilitating the secondary utilization of the sludge, having a good environmental protection effect, and avoiding directly discharging the sludge along with the sewage into the environment, which not only causes secondary waste but also burdens the environment.

[0044] On the other hand, a method for dewatering and solidifying municipal environmental sludge includes the following steps:

[0045] S101: Put the sludge into the sludge feeding funnel 3 and enter the lower semi-circular groove 22;

[0046] S103: By driving the driving part to operate, the driving part drives the sludge driving wheel 26 to rotate under the drive of the auxiliary power part. The sludge driving wheel 26 will drive the incoming sludge to roll, causing the sludge to roll and fall onto the blanking table 23, and then slide into the side fault push column 10 along the inclined surface of the blanking table 23;

[0047] S105: Drive multiple fault push columns 10 to slide up and down together by the driving part. When the fault push column 10 is pushed upward, the inclination angle of the top surface is parallel to the top surface of the adjacent fixed ladder plate 9 on the side, so that the fault push column 10 pushes the falling sludge upward. Under the upward push, the sewage contained in the sludge flows downward through the water outlet channel 11 and enters the inclined filter plate 7 below to achieve re-filtration;

[0048] S107: The overflowing sewage passes through the first activated carbon filter plate 25 below for multiple filtrations;

[0049] S109: The sewage after multiple filtrations is discharged from the sewage outlet 6;

[0050] S1011: The filtered sludge is pushed forward section by section by the fault push column 10. After multiple pushes, the contained sewage is filtered out, and the remaining sludge is pushed to the first discharge inclined opening 8 and enters the first disk 68, and is conveyed downward through the upper through hole 69 in the middle;

[0051] S1013: The first driving motor 59 operates, driving the middle gear 61, which in turn drives the side gear 58 to rotate. The side gear 58 then drives the mating threaded lifting rod 64, causing the threaded lifting rod 64 to perform a lifting motion.

[0052] S1015: The threaded lifting rod 64 drives the second disc 65 to move up and down reciprocally. The distance between the second disc 65 and the first disc 68 will constantly change, and the sludge that enters through the changing distance trajectory is compressed and stretched, achieving a better sludge extraction effect.

[0053] S1017: The sludge inside the left cavity is pressed under the compression motion generated by the compression component and finally discharged from the sludge outlet 18.

[0054] To facilitate the understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0055] In practical applications, the sludge is put into the sludge feeding funnel 3. The sludge falls from the feeding channel 21 and enters the sludge driving wheel 26 below. When the second motor 41 is driven, the second motor drives the fifth pulley 43 to rotate. The fifth pulley 43 drives the sixth pulley 49 to rotate through the third belt 50. The sixth pulley 49 drives the third rotating shaft 40 inserted in the middle to rotate. The third rotating shaft 40 drives the second bevel gear 39 at the end. After the second bevel gear 39 rotates, it drives the first bevel gear 38 meshing on the side to rotate. The first bevel gear 38 drives the second rotating shaft 37 connected on the side. The second rotating shaft 37 drives the second pulley 35 sleeved on the upper part. The second pulley 35 drives the first pulley 32 to rotate through the first belt 36. The first pulley 32 drives the first rotating shaft 30 inserted in the middle to rotate. The first rotating shaft 30 drives the third pulley 31 to rotate. The third pulley 31 drives the fourth pulley 28 to rotate through the second belt 33. After the fourth pulley 28 rotates, it drives the connected sludge driving wheel 26. After the sludge driving wheel 26 rotates, it rolls with the falling sludge. The sludge inside is lifted and conveyed to one side under the rolling and turning motion. The sludge enters the fault pushing column 10 on the side with the rolling motion. When the third rotating shaft 40 rotates, the third rotating shaft 40 drives the eccentric rotating wheel 48 at the other end to rotate. The eccentric rotating wheel 48 drives the driving plate 47 eccentrically connected on the side. The driving plate 47 pushes the fault pushing column 10 to move up and down. When the fault pushing column 10 moves up and down, the sludge falling above will be continuously lifted. Since the top surface of each fault pushing column 10 is inclined to the same side, the sludge above will slide down to the next adjacent fixed ladder plate 9 along the inclination of the inclined surface. Among them, when the sludge moves upward under the pushing, the contained sewage flows downward through the water outlet channel 11, passes through the filter screen 12 arranged at the top, and falls onto the inclined filter plate 7 below. Some of the falling sewage contains impurities or larger particulate matter and will be intercepted by the inclined filter plate 7 and slide into the left cavity through the second discharge inclined port 17 along the inclined surface of the inclined filter plate 7. The filtered liquid is filtered again and then passes through the first activated carbon filter plate 25 below for multiple filtrations. Finally, the filtered liquid is discharged from the sewage outlet 6.

[0056] When the fault push column 10 pushes the sludge forward step by step in a fault mode, as the sludge moves down along multiple intermittent inclined planes, the transmission path will become larger, and the solidification time of the sludge will increase accordingly. With the increase in the path, the sludge is pushed to the first discharge inclined opening 8 and enters the first disc 68 in the left cavity from the first discharge inclined opening 8, and is conveyed downward through the upper through hole 69. During this period, the driving motor 59 operates, and the motor 59 drives the middle gear 61 to rotate. After the middle gear 61 rotates, it will drive the side gear 58 engaged on the side. After the side gear 58 rotates, it will drive the threaded lifting rod 64 inserted and fitted in the middle, causing the threaded lifting rod 64 to pull the second disc 65 up and down. The upper part of the threaded lifting rod 64 reciprocally passes through the treatment tank 1 during the lifting movement. Since the first disc 68 is fixed on the left cavity wall, when the threaded lifting rod 64 is moving up and down, it will pass through the first disc 68 and pull the second disc 65 to reciprocally move up and down, causing the distance between the first disc 68 and the second disc 65 to constantly change. After the distance between them becomes smaller, the space between them will become smaller, and the shuttling sludge will be extruded under the compression movement between the first disc 68 and the second disc 65, increasing the coagulability of the sludge, so that the compressed sludge is discharged from the sludge outlet 18, facilitating its secondary use.

[0057] Through the above specific embodiments, those skilled in the technical field can easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific embodiments. Based on the disclosed embodiments, those skilled in the technical field can arbitrarily combine different technical features to implement different technical solutions.

A method for dewatering sludge in the municipal environment, characterized in that, For the municipal environmental sludge dewatering and solidifying device described in claim 8, it includes the following steps: Put the sludge into the sludge feeding funnel (3) and enter into the lower semi-circular groove (22). By driving the driving part to operate, the driving part drives the sludge driving wheel (26) to rotate under the drive of the auxiliary power part. The sludge driving wheel (26) will drive the entering sludge to roll, causing the sludge to tumble onto the blanking table (23) and slide down along the inclined surface of the blanking table (23) onto the side fault pushing column (10). Drive multiple fault pushing columns (10) to slide up and down together through the driving part.

Under the upward push, the sewage contained in the sludge flows downward through the water outlet channel (11) and enters the inclined filter plate (7) below to achieve re-filtering. The overflowing sewage is filtered multiple times through the lower first activated carbon filter plate (25). The sewage after multiple filtrations is discharged from the sewage outlet (6). The filtered sludge is pushed forward section by section through the fault pushing column (10). After multiple pushes, the contained sewage is filtered out, and the remaining sludge is pushed to the first discharge inclined opening (8), enters the first disk (68), and is conveyed downward through the upper through hole (69) in the middle. Operate the driving motor one (59). The motor one (59) drives the middle gear (61), and then drives the side gear (58) to rotate.
