Description

Technical Field

[0001] The present invention relates to the technical field of automated processing devices, and specifically to an automated device for efficiently processing sludge and sewage. Background Technique

[0002] A sewage and sludge treatment device is a device used to separate sludge from water for further treatment or discharge of the treated water. Sludge is a solid waste generated during the sewage treatment process. If not treated in a timely manner, it will cause immeasurable harm to the environment and human health. In addition, the treatment of sludge will also have an adverse impact on sewage treatment facilities and the surrounding environment. Therefore, separation and treatment must be carried out in a timely manner.

[0003] The process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it. In sewage treatment, the solid-liquid separation method is generally adopted. First, water and sludge are separated, and then the separated sludge is collected or transported. The sewage needs to be purified twice before it can be put into use. When the automated program is started, an automated device is required to treat the sewage.

[0004] Therefore, in the prior art, the patent with the authorization number CN108585251B discloses that a single motor is used as the power source, and multiple reflux channels are installed at the sewage source. A pair of sewage treatment devices are installed on the motor drive shaft. The treatment device contains multiple treatment nets. The multiple treatment net devices rotate above the reflux channels to block the flow of water, so that solid-liquid separation is carried out inside the reflux channels. In this way, it completely depends on the output frequency of the motor. The exposed problems are as follows: When the motor rotates slowly, in order to ensure that the dirt on the treatment net can flow into the collection box to avoid centrifugal force during rotation, the dirt still gets stuck on the treatment net. However, it is very likely that the adjacent treatment nets cannot be connected properly, resulting in the inability to block the flow of water, causing water pollution to the subsequent water source. In this case, the rotation speed needs to be increased so that when the treatment net rotates, the dirt on the treatment net device can just flow into the collection box. However, in this case, the adjacent treatment nets in the treatment net device must be perfectly connected. Each treatment net has a short time to treat dirt, and the centrifugal force generated causes the treatment net to not be able to discharge the dirt in time, so that some dirt still remains on the net. After a long time, it will get stuck on the dirt net and cause the filtration effect to deteriorate. For this reason, we propose an automated device for efficiently processing sludge and sewage. Summary of the Invention

[0005] The purpose of the present invention is to provide an automated device for efficiently processing sludge and sewage to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present invention provides the following technical solution: An automated device for efficiently treating sludge and sewage, including a housing. A central plate is installed in the middle of the housing. A separation plate is installed above the central plate. A spiral line is installed on the top of the separation plate. A driving device for driving the separation plate to rotate is installed below the central plate. A cleaning component for cleaning the dirt on the surface of the separation plate is installed on one side of the housing; The cleaning component includes a fixed slot provided on the housing, a slider moving inside the fixed slot, a spring connected to the slider, a connecting plate provided at one end of the spring, a blocking plate fixed on one side of the connecting plate, a contact piece threadedly connected to the bottom of the connecting plate, and a shovel head provided at the bottom of the blocking plate and in contact with the top of the separation plate. A sliding cavity is opened at the top of the fixed slot. A pair of limit blocks are provided on both sides of the fixed slot near the sliding cavity. And the slider is fixed to the limit block by a pin; A connecting sleeve is installed at the bottom of the fixed slot and fixed to the housing; A drawer is installed at the bottom of one side of the housing.

[0007] Preferably, the driving device includes a large gear wheel provided on one side of the bottom of the central plate, a small gear wheel concentric with the large gear wheel provided on the large gear wheel, a first gear provided at the bottom of the housing and meshing with the large gear wheel, a second gear provided at the top of the first gear and meshing with the small gear wheel, a third gear provided at the top of the second gear, and a fourth gear provided at the top of the third gear. The third gear meshes with the small gear wheel and rotates at the same speed and in the opposite direction as the second gear. The fourth gear meshes with the large gear wheel.

[0008] Preferably, a central plate is installed in the middle of the housing. The fourth gear is coaxially connected to a receiving plate. The third gear is coaxially connected to a processing plate. The housing is provided with a limit line near the top of the processing plate. And the transmission shaft of the second gear is connected to the separation plate. A motor slot is installed at the position of the housing near the large gear wheel. The motor in the motor slot is connected to the large gear wheel. A plurality of water outlet holes are equidistantly opened at the top of the filtering slot of the housing. Water outlet pipes are installed on the water outlet holes.

[0009] Preferably, adsorption components for adsorbing and further treating the sewage after solid-liquid separation are installed on both sides of the housing. The adsorption components include filtering slots obliquely provided on both sides of the housing, rotating rods fixed to the inner circle of the filtering slots by shafts at both ends, spiral sheets sleeved on the outer circle of the rotating rods, and a plurality of filter elements filled in the inner circle of the rotating rods.

[0010] The treated sewage is discharged through the water outlet holes on the plates on both sides of the housing and flows into the filtering slot through the water outlet pipes. Since the filtering slot is obliquely placed, the positions where the water flows drop are not uniform. The water flow at the higher position will drive the spiral sheet to rotate according to the spiral discharge principle. When passing through the spiral sheet, the water flow at the lower liquid level will pass through the openings on the rotating rod, so that the filter elements located in the inner circle of the rotating rod can all come into contact with the sewage, further improving the purification effect of filtering impurities.

[0011] Preferably, a liquid flow rate acceleration component for increasing the sewage inflow is installed at the top of the casing near the separation plate. The liquid flow rate acceleration component includes a first rotating impeller disposed at the top of the casing and coaxially connected to the first gear, a second rotating impeller coaxially connected to the first gear and located at the bottom of the first rotating impeller, a first fixed wheel disposed on the casing and located between the two first rotating impellers, and a second fixed wheel disposed at the bottom of the second rotating impeller.

[0012] More preferably, the blades of the first rotating impeller and the second rotating impeller have the same inclination direction, the blades of the first fixed wheel and the second fixed wheel have the same inclination direction, and the blades of the first rotating impeller and the first fixed wheel have opposite inclination directions.

[0013] When an external pipeline is connected to the top of the casing, in order to improve the absorption effect of sewage, the first fixed wheel and the second fixed wheel are both fixed on the casing. When the sewage is above the first rotating impeller, the motor starts, and the first rotating impeller and the second rotating impeller rotate synchronously. The first rotating impeller and the first fixed wheel are staggered between every two impellers. Therefore, when the water flow passes through, the first rotating impeller cuts the water flow and enters the top of the first fixed wheel. Since the water flow generates a thrust at the first rotating impeller and will accelerate downward after contacting the top of the first fixed wheel, and so on, the drainage can be efficiently processed.

[0014] Compared with the prior art, the beneficial effects of the present invention are: (1) In the present invention, the arched design of the separation plate facilitates the flow of sludge and sewage to the edge due to the centrifugal force during the cleaning of sludge and sewage, which is convenient for spreading the sludge and sewage flat and separating them. Then, after the separation plate rotates, through the limiting effect of the spiral line, the sludge is located between the spiral pitches of the spiral line. After the contact piece contacts the spiral line, the fixed groove adaptively descends, which is convenient for the shovel head to fall onto the separation plate. When the separation plate rotates several times, the contact piece and the spiral line are separated, and the dirt is shaken off into the drawer by the resilience of the spring, which is beneficial to improving the cleaning of the separation plate and facilitating the increase of the amount of sewage and sludge processed by the separation plate.

[0015] (2) Through the design of the blade inclination direction, on the one hand, the water can flow downward quickly in the present invention, which can efficiently process the drainage. At the same time, under the action of the blades, the sewage and sludge are effectively separated, so that the sewage entering the adsorption component has less sludge content, enabling the adsorption component to effectively simplify the sewage and have a longer service life.

[0016] (3) In the present invention, a single motor controls different gears to rotate in different directions, and then further controls the separation plate, the treatment plate and the receiving plate through the gears, so that they rotate in different directions crosswise, which can better disperse and separate the sewage and sludge, and further improve the sewage treatment effect of the device.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all 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.

[0020] Please refer to Figures 1 - 8, the present invention provides a technical solution: an automated device for efficiently treating sludge and sewage, including a casing 1. A central plate is installed in the middle of the casing 1. A separation plate 7 is installed above the central plate. A spiral line 8 is installed on the top of the separation plate 7. A driving device for driving the separation plate 7 to rotate is installed below the central plate. A cleaning component 3 for cleaning the dirt on the surface of the separation plate 7 is installed on one side of the casing 1; the cleaning component 3 includes a fixed groove 19 provided on the casing 1, a slider 21 movable inside the fixed groove 19, a spring 22 connected to the slider 21, a connecting plate 23 provided at one end of the spring 22, a blocking plate 24 fixed to one side of the connecting plate 23, a contact piece 25 threadedly connected to the bottom of the connecting plate 23, and a shovel head 26 provided at the bottom of the blocking plate 24 and in contact with the top of the separation plate 7. A sliding cavity is opened at the top of the fixed groove 19. A pair of limit blocks 20 are provided on both sides of the fixed groove 19 near the sliding cavity, and the slider 21 is fixed to the limit blocks 20 through a pin; a connecting sleeve is installed at the bottom of the fixed groove 19 and fixed to the casing 1; a drawer 5 is installed on one side of the casing 1 at the bottom of the fixed groove 19.

[0021] Embodiment 1: In sewage treatment, sewage can be introduced from the source to the top of the casing 1 through a pipeline. During the sewage transportation process, the flow rate of the sewage inside the pipeline can be controlled, so that the sewage can flow onto the separation plate 7. In practice, the operator can choose a mesh or plate shape for the separation plate 7 according to the actual situation (also according to cost. Generally, the mesh has a better effect on solid-liquid separation of sewage, but there may be silk ribbons in the filamentous sludge of the mesh holes that are likely to block the holes, and the plate shape is slower and not easily blocked). Then, power is supplied to the driving device to make the separation plate 7 rotate. During the rotation of the separation plate 7, the sewage sludge can be separated. However, over time, the sludge on the separation plate 7 will gradually block the holes, which is not conducive to the treatment of sludge and sewage. Therefore, in the solution, a spiral line 8 is installed on the separation plate 7. The length of the shovel head 26 is equal to the pitch of the spiral of the spiral line 8. The middle part of the separation plate 7 is arched and its surface contacts the bottom of the shovel head 26. The position between the contact piece 25 and the shovel head 26 contacts the spiral line 8. When the shovel head 26 slides on the separation plate 7, the contact piece 25 slides on the contact spiral line 8 to ensure that the shovel head 26 does not derail. In practice, the shovel head 26 is fixed together by the blocking plate 24, and the blocking plate 24 is fixedly connected to the spring 22. The spring 22 is fixed on the slider 21, which makes the shovel head 26 only stay stationary within the pitch circle of the spiral line 8 (because the bottom inclined surface of the shovel head 26 abuts against the spiral line 8 and then abuts against the spiral line 8 through the contact piece 25, so that the shovel head 26 does not move). Then, after the separation plate 7 rotates several circles (designed according to the actual situation), when the shovel head 26 follows the spiral line 8 and just enters the center of the separation plate 7 due to the continuous pulling force of the spring 22, the shovel head 26 shovels the sludge along the trajectory of the spiral line 8 on the separation plate 7 and shovels the sludge to the position above the shovel head 26 for temporary collection. When the shovel head 26 is located at the center of the separation plate 7, that is, when the shovel head 26 finishes walking along the spiral line 8, due to the constraint of the spiral line 8, the spring 22 can pull the blocking plate 24, the contact piece 25 and the shovel head 26 as a whole back to the original position. Since the reset of the spring 22 is fast and can generate a rebound vibration, this is used to make the shovel head 26 have a sufficient vibration source during the reset process, and the sludge located on its top is vibrated into the drawer 5 for collection through the rebound. When the shovel head 26 needs to be used again, during the rebound process of the spring 22, the contact piece 25 contacts the spiral line 8. After contacting the spiral line 8, the whole will descend to make the shovel head 26 coincide with the pitch of the spiral line 8, and then the next cleaning work can be carried out. As for the filtered water, it will continue to the next layer for further treatment.

[0022] The arched design of the separation plate 7 facilitates the flow of sludge and sewage to the edge due to the centrifugal force during cleaning, making it easy to spread the sludge and sewage flat and separate them. Then, after the separation plate 7 rotates, due to the limiting effect of the spiral line 8, the sludge is located between the spiral pitches of the spiral line 8. After the contact piece 25 contacts the spiral line 8, the fixed groove 19 adaptively descends, facilitating the shovel head 26 to fall onto the separation plate 7. When the separation plate 7 rotates several times, the contact piece 25 separates from the spiral line 8, and the dirt is shaken off into the drawer 5 by the resilience of the spring 22, which is beneficial to improving the cleaning of the separation plate 7 and facilitating the increase in the amount of sewage and sludge processed by the separation plate 7.

[0023] The driving device includes a large gear wheel 12 provided on one side of the bottom of the middle plate, a concentric small gear wheel 13 provided on the large gear wheel 12, a first gear 14 provided at the bottom of the machine shell 1 and meshed with the large gear wheel 12, a second gear 15 provided at the top of the first gear 14 and meshed with the small gear wheel 13, a third gear 16 provided at the top of the second gear 15, and a fourth gear 17 provided at the top of the third gear 16. The third gear 16 is meshed with the small gear wheel 13 and rotates at the same speed and in the opposite direction as the second gear 15, and the fourth gear 17 is meshed with the large gear wheel 12.

[0024] It can be Figures 1 - 6 seen that in this solution, multiple gears are arranged vertically and each gear can rotate independently without interfering with the operation of other gears.

[0025] A middle plate is installed in the middle of the machine shell 1. The fourth gear 17 is coaxially connected with a receiving plate 11, the third gear 16 is coaxially connected with a processing plate 9. The machine shell 1 is provided with a limiting line 10 near the top of the processing plate 9, and the transmission shaft of the second gear 15 is connected to the separation plate 7. The machine shell 1 is provided with a motor slot 18 near the position of the large gear wheel 12, and the motor in the motor slot 18 is connected to the large gear wheel 12. The machine shell 1 is equidistantly provided with a plurality of water outlet holes at the top of the filter slot 401, and water outlet pipes 6 are installed on the water outlet holes. The middle plate arches towards the center of the bottom of the receiving plate 11.

[0026] Among them, it can be Figure 6It can be seen that a motor is installed inside the motor slot 18. After powering it on, when the second gear 15 drives the separation plate 7 to rotate, the third gear 16 drives the processing plate 9 to rotate, and the fourth gear 17 drives the receiving plate 11 to rotate. The four gears are of the same type. Among them, the rotation direction of the separation plate 7 is opposite to that of the processing plate 9 and the receiving plate 11. Since the fourth gear 17 meshes with the large gear runner 12, and the large gear runner 12 is on the outer circle of the small gear runner 13, driving the fourth gear 17 to rotate relatively fast. Therefore, after the sewage is separated on the limit line 10, it flows along the processing plate 9 to the receiving plate 11. And the rotation speed of the receiving plate 11 is faster than that of the processing plate 9, so that the sewage on the receiving plate 11 is centrifuged again through rotation to the middle plate in the middle of the casing 1, and then is discharged through the water outlet holes on both sides of the casing 1.

[0027] Adsorption components 4 for adsorbing and further treating the sewage after solid-liquid separation are installed on both sides of the casing 1. The adsorption components 4 include filter tanks 401 inclined on both sides of the casing 1, rotating rods 403 fixed at both ends on the inner circle of the filter tanks 401 by rotating shafts, spiral blades 402 sleeved on the outer circle of the rotating rods 403, and a plurality of filter elements 404 filled in the inner circle of the rotating rods 403.

[0028] The treated sewage is discharged through the water outlet holes on both sides of the casing 1 and flows into the filter tank 401 through the water outlet pipe 6. Since the filter tank 401 is placed obliquely, the positions where the water flows drop are not uniform. The water flow at the higher position will drive the spiral blade 402 to rotate according to the spiral discharge principle. When the water flow is at the spiral blade 402, the water flow at the lower liquid level will pass through the openings on the rotating rod 403, so that the filter elements 404 located in the inner circle of the rotating rod 403 can all come into contact with the sewage, further improving the purification effect of filtering impurities.

[0029] A liquid flow velocity acceleration component 2 for increasing the sewage inflow is installed at the top of the casing 1 near the separation plate 7. The liquid flow velocity acceleration component 2 includes a first rotating impeller 201 provided at the top of the casing 1 and coaxially connected with the first gear 14, a second rotating impeller 203 coaxially connected with the first gear 14 and located at the bottom of the first rotating impeller 201, a first fixed wheel 202 provided on the casing 1 and located between the two first rotating impellers 201, and a second fixed wheel 204 provided at the bottom of the second rotating impeller 203.

[0030] Embodiment 2: When an external pipeline is connected to the top of the casing 1, in order to improve the absorption effect of the sewage, both the first fixed wheel 202 and the second fixed wheel 204 are fixed on the casing 1. When the sewage is above the first rotating impeller 201, the motor starts, and the first rotating impeller 201 and the second rotating impeller 203 rotate synchronously. Figure 4It can be seen that the first rotating impeller 201 and the first fixed wheel 202 are staggered between every two impellers. The blade inclination directions of the first rotating impeller 201 and the second rotating impeller 203 are the same. The blade inclination directions of the first fixed wheel 202 and the second fixed wheel 204 are the same. The blade inclination directions of the first rotating impeller 201 and the first fixed wheel 202 are opposite. Therefore, when water flows through, the first rotating impeller 201 cuts the water flow and enters the top of the first fixed wheel 202. Since the water flow generates a thrust at the first rotating impeller 201, it will accelerate and flow downward after contacting the top of the first fixed wheel 202. In this way, the drainage can be efficiently processed by repeating this process.
