Description

Technical Field

[0001] The invention belongs to the technical field of sludge treatment, and in particular relates to a shearing device for breaking the wall of sludge microorganisms. Background Art

[0002] In sewage treatment projects, various coagulants or coagulants are generally added to make the suspended particles in the sewage lose stability, and the colloidal particles condense to form flocs. As the volume of the flocs increases further, they separate from the water phase under the action of gravity and precipitate to form a large amount of sludge. Among them, polyacrylamide has been widely used because of its easy availability of raw materials, excellent adsorption bridging effect and electrical neutralization effect, and good flocculation effect on sludge particles.

[0003] The most important step in sludge treatment is to separate the water in the sludge and reduce the volume of the sludge, thereby reducing the sludge volume load in the subsequent treatment links. However, most of the organic matter in the sludge is the cellular material of microorganisms, which is wrapped by cell walls and cell membranes; in addition, while polyacrylamide forms a composite colloidal network structure with the hydrophilic substances in the sludge, the long chains of polyacrylamide also wrap up a large amount of water, which leads to an increase in the amount of water and bound water inside the sludge floc particles, and a large resistance to subsequent filtration and dehydration. After dehydration using mechanical devices such as filter press and centrifugation, the water content of the sludge is still as high as 70% to 80%, which results in low sludge dehydration efficiency, long time consumption, and increased energy consumption cost of sludge dehydration.

DETAILED DESCRIPTION

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0020] See also Figure 1-Figure 8The present embodiment provides a shearing device for breaking the wall of sludge microorganisms, comprising a hollow wall-breaking tank 1, a wall-breaking cover 2, a heating component 3 and a shearing component 4. A feeding slot is provided on the top of the wall-breaking tank 1, one end of the wall-breaking cover 2 is hingedly matched with the feeding slot, and the wall-breaking cover 2 can lock or release its sealing matching relationship with the wall-breaking tank 1. The heating component 3 is arranged at the bottom outside the wall-breaking tank 1, and the shearing component 4 is arranged in the wall-breaking tank 1 for shearing the sludge in the wall-breaking tank 1. In the present scheme, the shearing component 4 is arranged, and when the heating component 3 heats the sludge in the wall-breaking tank 1, the sludge in the wall-breaking tank 1 is heated. The cell walls and cell membranes in the sludge will soften, and the shearing component 4 will work, which will destroy the softened cell walls and cell membranes, thereby allowing the internal water and bound water of the organic matter in the sludge to flow out, making it convenient for the subsequent dehydration of the sludge, and can improve the subsequent dehydration speed and dehydration efficiency of the sludge, solving the problem that the existing sludge device cannot destroy the cell walls and cell membranes of the organic matter in the sludge, resulting in the internal water and bound water surrounded by the cell walls and cell membranes cannot be easily dehydrated, resulting in low sludge dehydration efficiency, long time consumption, and increased energy consumption cost of sludge drying and dehydration.

[0021] Specifically, the shearing assembly 4 of the present scheme includes a shearing unit and a fixed plate 401, and the shearing unit includes a rotating plate 402, a shearing rod 403, a shearing block 404, a rotating rod 405 and a transverse rod 406. The rotating plate 402 is rotatably arranged in the wall-breaking pot 1, and the fixed plate 401 is arranged at the top in the wall-breaking pot 1. The surface of the rotating plate 402 is parallel to the surface of the fixed plate 401. The shearing rod 403 is vertically slidably arranged on the fixed plate 401. The top and bottom of the shearing rod 403 are respectively connected to the transverse rod 406 and the shearing block 404. The transverse rod 406 is provided with a transverse sliding groove, and the axial direction of the transverse sliding groove is perpendicular to the axial direction of the shearing rod 403. The rotating rod 405 is vertically arranged on the rotating plate 402, and one end of the rotating rod 405 is slidably arranged in the transverse sliding groove. The central axis of the rotating rod 405 is parallel to the rotating plate 401. The central axes of the plates 402 do not overlap with each other; by providing a rotating plate 402, when the rotating plate 402 starts to rotate, the rotating rod 405 provided on the rotating plate 402 will rotate around the central axis of the rotating plate 402, which makes the lateral position and vertical position of the rotating rod 405 change all the time during the rotation process. Since one end of the rotating rod 405 is located in the lateral sliding groove, when the lateral position of the rotating rod 405 changes, it manifests as the rotating rod 405 sliding in the lateral sliding groove; when the vertical position of the rotating rod 405 changes, it manifests as the rotating rod 405 driving the shear rod 403 to slide in the vertical direction, and then the shear rod 403 drives the shear block 404 to move toward the bottom of the wall breaking tank 1, so that the shear block 404 destroys the cell wall and cell membrane of the organic matter in the sludge.

[0022] According to the above embodiment, in order to speed up the destruction of the cell wall and cell membrane of the sludge organic matter in the wall breaking tank 1 by the shearing unit, the shearing unit of the present scheme is provided with a plurality of shearing units, and the plurality of shearing units are arranged at equal intervals along the axis direction of the wall breaking tank 1. By providing a plurality of shearing units, the plurality of shearing units jointly process the sludge, which can improve the speed and efficiency of destroying the cell wall and cell membrane of the organic matter in the sludge; in addition, in order to ensure that the plurality of shearing units can work synchronously, the shearing unit of the present scheme also includes a driving rod 407, a driving gear 408, and a driving gear 409. The driving rod 407 is coaxially connected to the rotating plate 402, and the driving gear 408 and the driven gear 409 are both rotatably coaxially arranged on the driving rod 407, and there is a meshing space between two adjacent rotating plates 402; the shearing assembly 4 also includes a rotating motor 410, a rotating shaft 411, a connecting chain 412, a connecting gear 413 and a plurality of meshing chains 414, and the plurality of meshing chains 414 are matched with the plurality of meshing spaces in a one-to-one correspondence, and any meshing chain 414 is arranged in the corresponding meshing space, and the meshing chain 414 is respectively connected with any meshing space. The driving gear 408 of the shearing unit is meshed and connected with the driven gear 409 of the adjacent shearing unit, the rotating motor 410 is arranged outside the wall-breaking pot 1, the rotating shaft 411 is coaxially connected with the output end of the rotating motor 410, the rotating shaft 411 penetrates the wall-breaking pot 1 and extends into the wall-breaking pot 1, the connecting gear 413 is coaxially arranged at one end of the rotating shaft 411 located in the wall-breaking pot 1, and the connecting chain 412 is respectively meshed and connected with the connecting gear 413 and the driven gear 409 of the adjacent shearing unit; the rotating shaft 411 is rotatably sealed and matched with the wall-breaking pot 1 ; By providing a rotating motor 410, when the rotating motor 410 starts working, the rotating motor 410 can drive the rotating shaft 411 to rotate, and then can drive the connecting gear 413 located on the rotating shaft 411 to rotate, and then the connecting gear 413 drives the connecting chain 412 meshing with it to rotate, thereby realizing the rotation of a single rotating plate 402. Since the corresponding meshing chains 414 are respectively connected to the corresponding two rotating plates 402, several rotating plates 402 can be rotated together, and finally the synchronous operation of each shearing unit is realized.

[0023] In addition, it is worth mentioning that the shearing assembly 4 of the present scheme also includes a plurality of stirring units 5, and the plurality of stirring units 5 are matched with the plurality of shearing units in a one-to-one manner, and any stirring unit 5 is arranged in the corresponding shearing unit; the stirring unit 5 includes a telescopic block 501, a stirring rod 502, a telescopic spring 503 and a stirring spring 504, the shearing block 404 and the shearing rod 403 cooperate to form a telescopic slot hole, the axial direction of the telescopic slot hole is parallel to the axial direction of the shearing rod 403, the shearing block 404 is also provided with a stirring slot hole, the stirring slot hole is connected to the telescopic slot hole, and the axial direction of the stirring slot hole is perpendicular to the axial direction of the telescopic slot hole; the telescopic block 501 and the telescopic spring 503 are both arranged in the telescopic slot hole, the telescopic block 501 is slidably arranged in the telescopic slot hole, the two ends of the telescopic spring 503 are respectively connected to the telescopic block 501 and the shearing rod 403, and the stirring rod 502 is slidable. It is movably arranged in the stirring groove hole, and a stirring spring 504 is arranged in the stirring groove hole. The two ends of the stirring spring 504 are respectively connected to the stirring rod 502 and the shear block 404. One end of the stirring rod 502 is arranged to be pressed against and fitted with the telescopic block 501, and the other end thereof can lock or release its fitting relationship extending out of the stirring groove hole; by providing a stirring unit 5, when the shear block 404 moves toward the bottom of the wall-breaking pot 1, the telescopic block 501 will first be pressed against and fitted with the bottom surface of the wall-breaking pot 1, and then the telescopic block 501 will overcome the force of the telescopic spring 503 and shrink into the telescopic groove hole. It is also worth mentioning that in this scheme, the lateral length of the telescopic block 501 increases gradually from top to bottom; such a setting, as the telescopic block 501 continues to shrink toward the telescopic groove hole, will cause the stirring rod 502 pressed against and fitted with the telescopic block 501 to gradually overcome the force of the stirring spring 504 and extend out of the stirring groove hole.

[0024] It should also be noted that the purpose of setting the stirring rod 502 in this scheme is that when the shear block 404 moves toward the bottom of the wall-breaking tank 1 and cuts off the cell wall and cell membrane of the organic matter at the bottom, the stirring rod 502 will extend out of the shear block 404, and at this time, the length of the stirring rod 502 extending out reaches the longest after the shear block 404 and the bottom surface of the wall-breaking tank 1 are attached, and then when the shear block 404 moves toward the top of the wall-breaking tank 1 again, the stirring rod 502 will still extend out of the shear block 404, and the extended length remains unchanged, until the shear block 404 moves toward the top of the wall-breaking tank 1 and reaches the highest point, the stirring rod 502 will retract into the corresponding stirring slot due to the force of the stirring spring 504. It is worth noting that in the actual process of sludge treatment, the destruction of the cell wall and cell membrane of the organic matter requires that it is heated to a specified temperature in advance to soften it, so as to ensure that the shear block 404 destroys the cell wall and cell membrane of the organic matter. In the actual working process, since there are a large amount of organic matter and a large amount of water in the sludge, during the process of heating the sludge by the heating component 3, usually only the sludge close to the heating component 3 can be heated to the specified temperature, while the rest of the sludge needs to be heated for a considerable period of time due to the barrier of water in the organic matter before it can reach the specified temperature. In order to reduce the energy consumption cost of the device, the present scheme is provided with a stirring unit 5. When the shear block 404 destroys the cell wall and cell membrane of the organic matter at the bottom of the wall-breaking tank 1, the stirring rod 502 extends out. After the shear block 404 moves toward the top of the wall-breaking tank 1, the stirring rod 502 moves along with the movement of the shear block 404 to paddle the organic matter at the top of the stirring rod 502. On the same vertical plane, the organic matter at the top and middle of the wall-breaking tank 1 will gradually move toward the bottom of the wall-breaking tank 1 where the organic matter concentration is low due to its high concentration. As the shear block 404 performs reciprocating motions for many times, the cell wall and cell membrane of the organic matter on the same vertical plane are finally destroyed.

[0025] It should also be noted that, since there are several shearing units in this scheme, in order to ensure that during the operation of several shearing units, the organic matter whose cell walls and cell membranes have not been destroyed is sheared, it is necessary to ensure that the shear block 404 can only shear the organic matter within the width area projected to the bottom surface of the wall-breaking tank 1, and the length dimension of the shear block 404 projected to the bottom surface of the wall-breaking tank 1 is less than the width dimension of the bottom surface of the wall-breaking tank 1, and the length dimension of the shear block 404 and the stirring rod 502 projected to the bottom surface of the wall-breaking tank 1 when extended is equal to the width dimension of the bottom surface of the wall-breaking tank 1. Through such a setting, when the shear block 404 moves toward the bottom of the wall-breaking tank 1 for the first time to perform shearing, due to the extension of the shear block 404, the organic matter located at the top and middle of the wall-breaking tank 1 will diffuse and move to the surroundings, but as long as the speed of the first descent of the shear block 404 is controlled to be reduced to a certain extent, the movement range of the diffused organic matter will not be too large, and thus there will be no situation of affecting the shearing work of the adjacent shear blocks 404. After the shear block 404 completes the first shearing process, the cell wall and cell membrane of the organic matter at the bottom of the wall-breaking tank 1 are destroyed, and the stirring rod 502 extends to stir and slide the organic matter located in the same vertical plane area and outside the length area where the shear block 404 is projected to the bottom of the wall-breaking tank 1. Since the organic matter in this area is stroked by the stirring rod 502, the stability of this area is broken, and then the organic matter in this area will fall to the bottom of the length area where the shear block 404 is projected to the bottom of the wall-breaking tank 1 due to the concentration difference, and the organic matter in the surrounding area of ​​the same vertical plane area is not stroked by the stirring rod 502, so the organic matter in this area is still stably stacked; through this principle, after the shear block 404 performs multiple reciprocating motions, the cell wall and cell membrane of the organic matter in the vertical plane area can be destroyed. In this way, it is ensured that during the operation of several shearing units, the organic matter whose cell wall and cell membrane have not been destroyed is sheared, and the speed and efficiency of the shearing of the cell wall and cell membrane of the organic matter in this scheme are further improved.

[0026] It should also be noted that, in order to ensure further shearing treatment of the organic matter in the vertical area, in this solution, the width of the shear block 404 decreases from top to bottom; while the width of the stirring rod 502 increases.

[0027] According to the above embodiment, in order to ensure that the stirring rod 502 still extends out of the stirring slot hole during the rising of the shear block 404. The shear assembly 4 of this scheme also includes a plurality of locking units 6, and the plurality of locking units 6 are matched one-to-one with the plurality of shear units. Any locking unit 6 is arranged in the corresponding shear unit; the locking unit 6 includes a locking spring 601 and a locking block 602. A locking slot hole is provided in the shear rod 403, and the locking slot hole is connected to the telescopic slot hole. The locking spring 601 and the locking block 602 are both arranged in the locking slot hole. The locking block 602 is slidably arranged in the locking slot hole. The two ends of the locking spring 601 are respectively connected to the locking block 602 and the shear rod 403; the locking block 602 extends to a position outside the locking slot hole. The bottom of the end is tilted, and the vertical height of the locking block 602 gradually decreases along the axial direction extending out of the locking slot; the telescopic block 501 is provided with a matching slot, and the locking block 602 can lock or release its connection and matching relationship with the matching slot; through such a setting, when the telescopic block 501 is fully retracted into the telescopic slot, the locking block 602 will cooperate with the matching slot on the telescopic block 501, so that the telescopic block 501 cannot return to its original position. Such a setting ensures that after the shear block 404 moves toward the top of the wall-breaking pot 1, the telescopic block 501 cannot return to its original position, thereby ensuring that the stirring rod 502 always extends out of the stirring slot.

[0028] In addition, in order to achieve the structural effect that the stirring rod 502 is retracted in the stirring groove hole due to the force of the stirring spring 504 after the shear block 404 rises to a specified height, the locking unit 6 of the present scheme also includes a pressing spring 603, a pressing block 604, a sliding block 605 and a connecting block 606, the pressing block 604 is slidably arranged at one end in the transverse sliding groove, the pressing spring 603 is arranged in the transverse sliding groove, and the two ends of the pressing spring 603 are respectively connected to the pressing block 604 and the transverse rod 406; a connecting slot hole is provided in the shear rod 403, and the connecting slot hole is respectively connected to the interior of the shear rod 403 and the interior of the wall-breaking pot 1; the sliding block 605 is slidably arranged in the connecting slot hole, and a locking slot hole is provided on the sliding block 605, and the two ends of the connecting block 606 are respectively connected to the pressing block 604 and the sliding The movable blocks 605 are connected to each other, and the pressing block 604 can lock or release its pressing cooperation relationship with the rotating rod 405; by providing the pressing block 604, when the shear block 404 rises to the specified height, the rotating rod 405 is located at one end of the horizontal sliding groove, and the rotating rod 405 will cooperate with the pressing block 604 to drive the pressing block 604 to slide, so that the connecting block 606 and the sliding block 605 connected to the pressing block 604 slide together, thereby releasing the cooperation relationship between the locking block 602 and the matching slot hole, and the telescopic block 501 will be reset due to the action of the telescopic spring 503, and the stirring rod 502 will retract back into the stirring slot hole, and after the rotating rod 405 slides toward the rest of the horizontal sliding slot, the pressing block 604 will also return to its original position due to the pressing spring 603.

[0029] According to the above embodiment, a single shearing unit can only shear the cell walls and cell membranes of organic matter projected onto the bottom area of ​​the wall-breaking pot 1, and since there is a gap between the areas where two adjacent shearing units are projected onto the bottom area of ​​the wall-breaking pot 1, the above structure cannot shear the organic matter in the gap between the areas where two adjacent shearing units are projected onto the bottom area of ​​the wall-breaking pot 1; based on this, the present scheme also includes a pushing component 7, the pushing component 7 includes a pushing cylinder 701, a pushing block 705 and a control unit, the pushing cylinder 701 is arranged outside the wall-breaking pot 1, the output end of the pushing cylinder 701 is slidably sealed and arranged inside the wall-breaking pot 1, and the pushing block 705 is 05 is slidably sealed in the wall-breaking tank 1, the output end of the pushing cylinder 701 is connected to the pushing block 705, the pushing block 705 changes the volume in the wall-breaking tank 1 by sliding, and the control unit is communicated with the pushing cylinder 701 to control the operation of the pushing cylinder 701; it should be noted that, in the present embodiment, the interior of the wall-breaking tank 1 and the pushing block 705 together form a filling space, the shearing component 4 and the sludge are both located in the filling space, therefore, by controlling the sliding of the pushing block 705, the volume of the filling space can be changed, thereby pushing the untreated sludge area to the bottom of the corresponding shearing unit to achieve shearing treatment.

[0030] Specifically, the control unit of the present scheme includes a control rod 702, a control module 703 and a control spring 704. A control slot is provided on the top of the wall-breaking pot 1. The control module 703 is arranged in the control slot. The control rod 702 is slidably arranged in the control slot. The control spring 704 is arranged in the control slot. Both ends of the control spring 704 are respectively connected to the control rod 702 and the wall-breaking pot 1. The control module 703 is communicated with the pushing cylinder 701. The control rod 702 can lock or release its pressing fit relationship with the control module 703. By providing the control rod 702, as the heating component 3 continues to work, the temperature in the wall-breaking pot 1 rises, which will cause the water vapor in the wall-breaking pot 1 to be vaporized into water vapor, and then the air pressure in the wall-breaking pot 1 gradually increases. The increased air pressure will drive the control rod 702 to overcome the control spring 704 to slide, so that the control rod 702 presses the control module 703, and then controls the pushing cylinder 701 to work.

[0031] It is worth noting that during the operation of the heating component 3, the shearing unit is also continuously performing shearing processing. Therefore, when the shearing unit destroys the cell walls and cell membranes of the organic matter in the area, the moisture of the organic matter will flow out, thereby absorbing the heat in the area and slowing down the speed at which the moisture in the wall-breaking pot 1 is converted into water vapor, until the shearing unit completes the shearing processing in the area, so that there is no more moisture in the wall-breaking pot 1 to absorb the heat in the area, and then the moisture in the wall-breaking pot 1 is converted into water vapor, thereby increasing the pressure in the wall-breaking pot 1, driving the control rod 702 to press the control module 703, and realizing the operation of the pushing cylinder 701. When the pushing cylinder 701 is working, the shearing unit stops working.

[0032] It is also worth mentioning that when the shearing unit needs to perform shearing on the remaining areas that have not been sheared, in order to ensure that the air pressure is normal at this time, it is also necessary to reduce the air pressure in the wall-breaking tank 1 before the shearing unit works. Based on this, an air release slot is also provided in the wall-breaking tank 1 of this scheme, one end of which is connected to the external environment, and the other end of which is located in the side wall of the control slot. The air release slot can lock or release its connection and matching relationship with the inside of the wall-breaking tank 1 through the sliding of the control rod 702. By providing the air release slot, when the control rod 702 presses the control module 703, the air release slot is connected to the inside of the wall-breaking tank 1, and the air pressure in the wall-breaking tank 1 will overflow with the air release slot, reducing the air pressure in the wall-breaking tank 1. After the air pressure in the wall-breaking tank 1 returns to normal, the cylinder 701 is pushed to stop working, and the shearing unit restarts working until all the organic matter in the wall-breaking tank 1 is sheared.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention.
