Description

Technical Field

[0001] The invention relates to a scraper structure capable of driving the scraper to change different angle positions, which can reduce movement resistance and make the scraper to move back and forth and scrape mud more smoothly. Background Art

[0002] The sedimentation tank is used for the suspended particles contained in the incoming raw water to settle at the bottom of the tank. Over time, the suspended particles accumulate into a sludge layer with a certain thickness. Therefore, a sludge collection tank and a sludge scraping device are provided in the sedimentation tank to scrape the sludge to the sludge collection tank.

[0003] A general scraper device is provided with a slidable slide plate on the sedimentation tank, and a plurality of horizontal scraper plates are mounted on the slide plate. The side of the scraper plate facing the sludge collecting tank is approximately vertical to the wall, and the side away from the sludge collecting tank is formed with an inclined surface. The scraper device is driven by a transmission device, and the scraper plate can slide back and forth on the sedimentation tank repeatedly to scrape up the sludge and push it into the sludge collecting tank.

[0004] The above-mentioned scraper device has the following problems when in use:

[0005] Although the scraper device can scrape the sludge at the bottom of the sedimentation tank and collect it in the sludge collecting trough, the repeated back and forth movement causes the sliding plate to generate resistance during its movement due to the sedimentation of the sludge, and the sliding plate is in direct frictional contact with the bottom of the sedimentation tank, resulting in uneven movement. In addition, although an inclined surface is formed on the side of the scraper plate facing away from the sludge collecting trough, when the scraper plate moves back, the sludge will cross the inclined surface and reach the side of the vertical wall surface, but in the process of the sliding plate moving back, because the scraper plate does not change its angle or height, part of the sludge will still be driven back, resulting in a poor overall scraping effect.

[0006] How to solve the above problems and deficiencies is the direction that the applicant of the present invention and related manufacturers engaged in this industry are eager to study and improve. Summary of the invention

[0007] The present invention mainly provides a design of a guiding protrusion through a guide member, which cooperates with the limiting groove of a moving component to achieve smooth reciprocating movement of the lower bracket without causing unsmooth movement due to friction between the lower bracket and the bottom of the sedimentation tank. The overall sludge scraping action can be faster, effectively shortening the scraping time and increasing the overall efficiency.

[0008] Another main problem of the present invention is to provide an upper bracket pivot portion through the upper bracket and the lower bracket pivot portion of the lower bracket, and cooperate with the first pivot portion and the second pivot portion of the scraper device to pivot each other, so that the scraper blade can be driven by the flip member to move in different directions between the upper bracket and the lower bracket, and can drive each flip member to move in an angle direction, and flip each scraper blade from a first state to a second state. The scraper blade can change its action between a vertical state and a horizontal state, so that the scraper blade can scrape the sludge when it is in a vertical state. When the scraper blade is in a horizontal state and the inclined surface of the flip member faces backward, the scraper device will not bring the sludge back when it quickly returns to its original position, which has a stable effect on the overall scraping efficiency.

[0009] The main structure of the present invention that can achieve the above-mentioned main purpose includes a sedimentation tank, a driving device is provided on one side of the sedimentation tank, and several guide members are provided at the bottom of the sedimentation tank, each guide member includes a guiding protrusion, and a lower bracket is provided on the guide member, the lower bracket is connected to the driving device, and the lower bracket has several lower bracket pivot parts, and the lower bracket is pivoted with several moving components, each moving component has a limiting groove part, so that each moving component can move on the guide member, and an upper bracket is provided above the lower bracket, the upper bracket has several upper bracket pivot parts, and the upper and lower bracket pivot parts are respectively pivoted with a first pivot part and a second pivot part of a scraper device, and the scraper device also has a scraper plate and several flip parts, and each flip part has a vertical surface and an inclined surface combined with the scraper plate.

[0010] When the driving device drives the lower bracket to move forward, the scraper blade will present a first state (i.e. a vertical state), and then scrape the sludge in the sedimentation tank, and the moving component can be limited to move on the guide protrusion through the limiting groove. In addition, before the driving device drives the lower bracket to move backward, the upper bracket will first be resisted by a force in a direction different from the forward direction of the lower bracket. At this time, the upper bracket can be separated from the lower bracket with the cooperation of the flip part, and the scraper blade will present a second state (i.e. a horizontal state), and the inclined surface will face backward, so that the scraper blade can be quickly restored to its original position until the upper bracket is subjected to another reverse force to make the upper bracket contact with the lower bracket, and the scraper blade returns to a vertical state, and then performs the scraping action again.

[0011] By means of the above-mentioned technology, the existing problem of conventional scraper devices can be solved. Although the sludge at the bottom of the sedimentation tank can be scraped off and collected by the sludge collecting trough, the sedimentation of sludge during the repeated back-and-forth movement causes resistance to the sliding plate during its movement, and the sliding plate is in direct frictional contact with the bottom of the sedimentation tank, resulting in uneven movement. In addition, although an inclined surface is formed on the side of the scraper plate facing away from the sludge collecting trough, the sludge will cross the inclined surface and reach the side of the vertical wall when the scraper plate moves back. However, during the process of the sliding plate moving back, the scraper plate does not change its angle or height, so that part of the sludge will still be driven back, resulting in poor overall scraping effect. This problem is solved, thereby achieving the practical progress of the present invention as described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Please refer to the first to sixth figures, which are perspective views to side views of the flip member of the first preferred embodiment of the present invention. It can be clearly seen from the figures that the present invention includes:

[0014] A sedimentation tank 1, a sludge collecting tank 11 and an inclined portion 12 are provided at the bottom of the sedimentation tank 1, the guide member 3 described below is provided on the inclined portion 12, so that the sludge can naturally move to the sludge collecting tank 11 through the inclined portion 12 and accumulate, and the sedimentation tank 1 is provided with a plurality of abutting members 13 for abutting the upper bracket 5 described below in the direction in which the lower bracket 4 described below moves;

[0015] A driving device 2 is provided at one side of the sedimentation tank 1, and the driving device 2 has a connecting rod set 21 and a driving member 22 pivotally provided with the connecting rod set 21 and combined with the lower bracket 4 described below, so that the driving member 22 drives the lower bracket 4 described below to move by the connecting rod set 21;

[0016] A plurality of guide members 3 are disposed at the bottom of the sedimentation tank 1 , each of the guide members 3 comprises a guide protrusion 32 , and a guide base 31 is disposed on one side of the guide protrusion 32 ;

[0017] A lower bracket 4 is provided on the guide member 3 and connected to the driving device 2. The lower bracket 4 is pivotally provided with a plurality of moving components 41. Each of the moving components 41 has a limiting groove portion 411 in contact with the guide protrusion 32, so that each of the moving components 41 can move on the guide member 3. The lower bracket 4 has a plurality of lower bracket pivot portions 42. In addition, the moving component 41 has two fixing plates 412 fixed on the lower bracket 4, a central axis 413 provided between each of the fixing plates 412, a partition portion 414 provided on the central axis 413, and two wheel bodies 415 respectively pivotally provided on the central axis 413. The limiting groove portion 411 is formed by the isolation between each of the wheel bodies 415 through the partition portion 414;

[0018] An upper bracket 5 is disposed above the lower bracket 4. The upper bracket 5 has a plurality of upper bracket pivot portions 51, and a plurality of reinforcing members 52 are disposed on the upper bracket 5. A reinforcing rod 53 is disposed between each of the reinforcing members 52. The reinforcing members 52 and the reinforcing rod 53 are used to lift the scraper 61 during the scraping action. The upper bracket 5 can be more stable, so that the scraper 61 will not break when scraping a larger amount of sludge; and

[0019] A plurality of scraper devices 6 are provided, each of which comprises a scraper blade 61 and a plurality of flipping members 62 fixed to the scraper blade 61. Each flipping member 62 has a vertical surface 621 combined with the scraper blade 61, an inclined surface 622 located on a different side of the vertical surface 621, a first pivoting portion 623 pivoted to the pivot portion 42 of the lower bracket, and a second pivoting portion 624 pivoted to the pivot portion 51 of the upper bracket. The lower bracket 4 is thereby engaged with each of the guide members 3 through each of the moving components 41, so that the lower bracket 4 can be reciprocated. Furthermore, through the displacement in different directions between the upper bracket 5 and the lower bracket 4, each of the flipping members 62 can be driven to move in an angle direction, so that each of the scraper blades 61 is flipped from a first state to a second state.

[0020] The scraper blade 61 has a scraper surface 611 and a reinforced bending portion 612 extending from one end of the scraper surface 611 .

[0021] The sedimentation tank 1 in this embodiment takes a tank body as an example.

[0022] The driving device 2 in this embodiment is taken as a motor.

[0023] The guide member 3 in this embodiment is a track.

[0024] The flip member 62 in this embodiment is triangular in shape and has the vertical surface 621 and the inclined surface 622 .

[0025] The first pivoting portion 623 and the second pivoting portion 624 are exemplified by holes in this embodiment. The upper support pivoting portion 51 and the lower support pivoting portion 42 are exemplified by crossbars in this embodiment.

[0026] The reinforcement member 52 in this embodiment is taken as an angle steel.

[0027] The resisting member 13 in this embodiment is taken as a rod.

[0028] Please refer to the first to fourteenth figures at the same time, which are the three-dimensional diagram of the first preferred embodiment of the present invention and the schematic diagram of the scraping device turned down. It can be clearly seen from the figure that the sedimentation tank 1 of this case can be used to treat the sludge A of tap water or wastewater. After the water source to be treated enters the sedimentation tank 1 for a period of time, due to the relationship of the inclined portion 12, the sludge A will naturally move to a lower place (that is, close to the side of the sludge collection tank 11) and accumulate. In other words, the original sludge A in the water source will begin to settle at the bottom of the sedimentation tank 1. At this time, the driving device 2 can be started, and the driving device 2 can be continuously driven by the connecting rod group 21 to pull back or push the driving member 22. When the sludge A is to be scraped off, the connecting rod group 21 pulls back the driving member 22, so that the lower bracket 4 is moved toward the sludge collecting tank 11. At this time, the limiting groove 411 formed by the two wheel bodies 415 and the partition 414 accommodates the guide protrusion 32, so that the moving component 41 can roll on the guide member 3 without deviating from the runway. It can move forward and backward in the same direction, and the friction between the lower bracket 4 and the bottom of the sedimentation tank 1 will not generate resistance. In addition, the central axis 413 and the fixing plate 412 allow the wheel body 415 to roll smoothly and be stably fixed on the inner wall of the lower bracket 4 at the same time, so as to achieve the advantages of smooth movement, stability, durability, etc. The above can be referred to Figures 5 and 7.

[0029] During the process of the link group 21 pulling back the driving member 22, the scraper plate 61 of the scraper device 6 will be in the first state, and the vertical surface 621 and the scraper surface 611 will be located in the direction of the sludge collecting tank 11 (i.e., the vertical state). At this time, the upper bracket 5 and the lower bracket 4 are in a close contact state, which means that the relative position of the lower bracket pivot portion 42 (first pivot portion 623) and the upper bracket pivot portion 51 (second pivot portion 624) is not on a vertical line, but in a relative position relationship in a diagonal manner. When the lower bracket 4 moves, the scraper surface 611 of the scraper plate 61 will begin to push the sludge A at the bottom of the sedimentation tank 1 toward the sludge collecting tank 11, and the reinforced bending portion 612 allows the scraper plate 61 to withstand a higher thrust strength and is not easily deformed. The above can be referred to Figures 4, 6, 7, and 8. When the first scraper blade 61 pushes the sludge A into the sludge collecting tank 11, at the same time, the upper bracket 5 will abut against one end of the supporting member 13. At this time, the lower bracket 4 is continuously pulled back by the driving device 2, so that the lower bracket pivot portion 42 and the first pivot portion 623 of the lower bracket 4 and the upper bracket pivot portion 51 and the second pivot portion 624 of the upper bracket 5 form another oblique position relationship from the original oblique position relationship, so that the upper bracket 5 is held away from the lower bracket 4 by the flip member 62, and the scraping surface 611 of the scraper blade 61 is also flipped upward from the original vertical state to form a horizontal state. The above can be referred to Figures 9 and 10.

[0030] Then the driving device 2 starts to push the lower bracket 4 forward, so that the lower bracket 4 is away from the sludge collecting tank 11, and the moving component 41 is guided by the direction of the guide member 3 and moves smoothly. At the same time, due to the lower resistance generated by the inclined surface 622, the driving device 2 can move forward faster (return to the original position). In addition, the scraper plate 61 is already in a horizontal state. When returning to the original position, it can pass over the sludge A pushed by the other scraper plate 61A without touching the sludge A and being pushed back in a large amount away from the sludge collecting tank 11. The above can be referred to Figures 11 and 12.

[0031] When the other end of the upper bracket 5 abuts against the abutting member 13A at the other end, the upper bracket 5 is in a stationary state, and the lower bracket 4 is still continuously driven forward by the driving device 2, so that the lower bracket pivot portion 42 and the first pivot portion 623 of the lower bracket 4 and the upper bracket pivot portion 51 and the second pivot portion 624 of the upper bracket 5 form another oblique position relationship from the original oblique position relationship, and the upper bracket 5 is also close to the lower bracket 4 due to the linkage of the flip member 62, and the scraping surface 611 of the scraper blade 61 is also flipped downward from the original horizontal state to form a vertical state. The above can be referred to Figures 13 and 14.

[0032] Thus, after the above-mentioned actions, the sludge A is pushed smoothly and quickly into the sludge collecting tank 11, and the sludge scraping action can be performed reliably.

[0033] Please refer to FIG. 15, which is a schematic diagram of the implementation of the second preferred embodiment of the present invention. It can be clearly seen from the figure that the difference between this embodiment and the above-mentioned embodiment is that the original reinforcing member and reinforcing rod are eliminated in this embodiment, which means that even if there is no reinforcing member and reinforcing rod design, the scraping action can still be performed. The reinforcing member and reinforcing rod added in the previous embodiment can further improve the scraping action of the scraper 61, and the upper bracket 5 can be more stable, so that the scraper 61 will not collapse when scraping a larger amount of sludge.

[0034] Please refer to FIG. 16, which is a schematic diagram of the limiting portion of the third preferred embodiment of the present invention. It can be clearly seen from the figure that the difference between this embodiment and the above-mentioned embodiments is that the driving member 22 of this embodiment has a limit portion 221 for the upper bracket 5 to abut against, so as to prevent the upper bracket 5 from turning over. When the connecting rod assembly of the driving device drives the pivotally arranged driving member 22, when the upper bracket 5 is supported by the supporting member and moves upward, the upper surface 54 of the upper bracket 5 will abut against the limit portion 221, so that the upper bracket 5 is blocked by the limit portion 221 before completing the apex of a circular motion, thereby preventing the scraper 61 from turning over.

[0035] Please refer to FIG. 17 , which is a schematic diagram of the reinforcement portion of the fourth preferred embodiment of the present invention. It can be clearly seen from the figure that the difference between this embodiment and the above-mentioned embodiment lies in that the guide protrusion 32 and the guide base 31 of this embodiment are respectively provided with reinforcement portions 33 on both sides of the connection position, which means that through the design of the reinforcement portion 33, the strength and durability of the guide protrusion 32 can be effectively enhanced without deformation.

[0036] Please refer to FIG. 18, which is a schematic plan view of the fifth preferred embodiment of the present invention. It can be clearly seen from the figure that the difference between this embodiment and the above embodiment is that the design of the inclined portion is eliminated in this embodiment, so that the bottom of the sedimentation tank 1 is horizontal rather than inclined, which means that even without the inclined portion, the sludge in this case can still be directly scraped by the scraper device 6 after falling to the bottom of the sedimentation tank 1, and its operation is not affected as a whole. In addition, the position of the sludge collecting tank 11 in this embodiment is opposite to that in the above embodiment, which means that the position of the sludge collecting tank 11 is not limited in this case.

[0037] Please refer to FIG. 19A and FIG. 19B for a schematic diagram of the implementation of the sixth preferred embodiment of the present invention. Figure 1 and two As can be clearly seen from the figure, the difference between this embodiment and the above-mentioned embodiment is that the abutting portion is eliminated in this embodiment, which means that when the upper bracket 5 moves up and down, it directly abuts against the two end walls of the sedimentation tank 1 to move upward. Although this will cause the stroke of the driving device 2 to be lengthened, the upper bracket 5 can still move up and down.

[0038] Please refer to FIG. 20, which is a schematic diagram of the implementation of the seventh preferred embodiment of the present invention. It can be clearly seen from the figure that the difference between this embodiment and the above-mentioned embodiments is that the scraper blade 61 of this embodiment cancels the reinforced bending portion and retains the scraping surface 611, which means that after canceling the reinforced bending portion, the scraper blade 61 of this case can still scrape the sludge at the bottom of the sedimentation tank through the scraping surface 611. Although it is not possible to scrape a larger amount of sludge, it can still scrape a general amount of sludge without affecting the overall scraping action.

[0039] Please refer to Figure 21, which is a schematic diagram of the moving component of the eighth preferred embodiment of the present invention. It can be clearly seen from the figure that the difference between this embodiment and the above-mentioned embodiment is that the moving component 41 of this embodiment presents the limiting groove portion 411 in the form of a groove, which means that the moving component 41 of this case can be composed of two wheel bodies or a single wheel body, and there is no limitation on the form, and the groove of the single wheel body can still engage with the guide protrusion 32, so that the guide protrusion 32 can be placed in the groove for guided walking.

[0040] Please refer to FIG. 22, which is a schematic diagram of the guide member of the ninth preferred embodiment of the present invention. It can be clearly seen from the figure that the difference between this embodiment and the above-mentioned embodiments lies in that the reinforcing parts respectively provided at both sides of the connecting position between the guide protrusion 32 and the guide base of this embodiment and the aforementioned guide base are all cancelled in this embodiment, which means that even if there is no guide base in this case, the guide protrusion 32 can still be established at the bottom of the sedimentation tank 1 to allow the moving component 41 to move smoothly on the guide protrusion 32, without affecting the scraping action and the overall effect.

[0041] The invention provides a scraper structure capable of driving the scraper blade to change different angles, which is a key technology for improving the conventional technology.

[0042] First, through the design of the guiding protrusion 32 of the guiding member 3, in conjunction with the limiting groove 411 of the moving component 41, the lower bracket 4 can move smoothly during the reciprocating movement without causing any irregularities due to the friction between the lower bracket 4 and the bottom of the sedimentation tank 1. The overall sludge A scraping action can be faster, effectively shortening the scraping time and increasing the overall efficiency.

[0043] Secondly, through the upper bracket pivot portion 51 of the upper bracket 5 and the lower bracket pivot portion 42 of the lower bracket 4, in conjunction with the pivoting between the first pivot portion 623 and the second pivot portion 624 of the scraper device 6, the scraper blade 61 can be driven by the flip member 62 to change its movement between the vertical state and the horizontal state, so that the scraper blade 61 can scrape the sludge A when it is in the vertical state. When the scraper blade 61 is in the horizontal state and the inclined surface of the flip member 62 is facing backward, the scraper device 6 will not bring the sludge A back when it quickly returns to the original position, which has a stable effect on the overall scraping efficiency.

[0044] Third, the sludge A will naturally move to a lower position and accumulate through the inclined portion 12, so that the sludge scraping device 6 can scrape the sludge more quickly and smoothly.

[0045] Fourthly, the supporting member 13 allows the driving device 2 to change the position of the upper bracket 5 in a shorter stroke, thereby improving the overall speed and efficiency of scraping mud.

[0046] Fifth, through the design of the reinforcement portion 33, the structural strength of the guiding protrusion 32 can be effectively increased and not easily broken.

[0047] Sixth, through the design of the reinforcing member 52 and the reinforcing rod 53, the upper bracket 5 can be more stable during the scraping action of the scraper 61, so that the scraper 61 will not break when scraping a larger amount of sludge A.

[0048] Seventh, when the vertical surface 621 of the flip member 62 is in a vertical position, the scraper 61 can scrape the sludge A. When the vertical surface 621 is in a horizontal position, the inclined surface 622 can move faster and more smoothly when the upper and lower brackets 5 and 4 are reset, and the pushed sludge A will not be brought back.

[0049] Eighth, by strengthening the design of the bending portion 612, the scraper blade 61 can withstand a higher thrust strength and is less likely to deform.
