Description

Technical Field

[0001] The invention relates to the field of filter pressing equipment, in particular to a port channel bottom mud sample filter pressing device. Background Art

[0002] The composition of port channel sediment is complex, containing a variety of pollutants and harmful substances. Through sediment dehydration, these harmful substances can be centrally treated to reduce the risk of environmental pollution. The detection of biological samples in port channel sediment and the detection of inorganic components in sediment are important contents of port channel ecological environment assessment and resource utilization of dredged sediment; therefore, during the detection, evaluation and subsequent resource utilization research of dredged sediment, a filter press device will be used to remove water from the sediment sample to obtain a test sample; the traditional filter press device is composed of a frame, a filter plate and a clamping device. The frame is a supporting structure made of high-strength metal, and a drain port is provided on the filter plate. The filter plate forms a filter chamber, and the sediment is filtered in the filter chamber. The clamping component can provide a large pressure to accelerate the discharge of the filtrate.

[0003] When conducting channel sediment inspection, assessment and subsequent resource utilization, stones and debris should be pre-screened as useless items. The reason is that when performing filter pressing, firstly, the stones and debris are large in size, which can easily lead to uneven force on the pressure plate during filter pressing and affect the filter pressing effect; secondly, stones and debris can easily damage the filter plate during the pressure application process and reduce the service life of the equipment.

[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0054] Embodiment 1:

[0055] like Figure 1 and Figure 2 As shown, the port channel sediment sample filter press device includes a base 1, a top plate 2, a bracket 3, a filtering mechanism 4, a hydraulic cylinder 5, a pressure plate 6, a de-impurity mechanism 7, a filter press screen 8 and a driving mechanism 9. The bracket 3 is installed on the base 1, and the bracket 3 is used to support the top plate 2.

[0056] The filter mechanism 4, the pressing plate 6, the impurity removal mechanism 7, the filter press screen plate 8 and the driving mechanism 9 together constitute a filter press unit, which is installed on the bracket 3 and is used to complete the filter press work of the bottom mud. The filter mechanism 4 is used to hold the bottom mud excavated from the port channel, and the water in the bottom mud can be filtered out by the cooperation of the hydraulic cylinder 5 and the pressing plate 6. The impurity removal mechanism 7 is used to automatically remove large pieces of debris in the filter mechanism 4 before the filter press work begins.

[0057] like Figure 2 , Figure 3 and Figure 4 As shown, the filter mechanism 4 includes two frames 41, a pressing seat 42, a pressing cavity 43, a filter hole 44 and a guide plate 45. An extension frame 12 is installed on the frame 41. The extension frame 12 is fixedly installed on the bracket 3. The relative position between the frame 41 and the bracket 3 can be fixed by the extension frame 12, thereby fixing the overall position of the filter mechanism 4. The pressing seat 42 is installed between the two frames 41, the pressing cavity 43 is arranged on the pressing seat 42, and the filter hole 44 is opened at the bottom of the pressing cavity 43. The pressing cavity 43 is a rectangular space, and the bottom mud is located therein. The wastewater will be discharged downward through the filter hole 44. The guide plate 45 is installed at the bottom of the pressing seat 42, and the guide plate 45 is arranged obliquely. The wastewater discharged through the filter hole 44 will fall on the guide plate 45. Due to the inclined arrangement of the guide plate 45, the directional discharge of the wastewater can be achieved. The filter press screen plate 8 is installed in the pressing chamber 43. The main body of the filter press screen plate 8 is a U-shaped plate. A baffle that can contact the outer wall of the pressing seat 42 is provided on the top. Its shape is adapted to the pressing chamber 43. The filter press screen plate 8 is placed in the pressing chamber 43, and its outer wall can fit with the pressing chamber 43, which not only ensures the stability after placement, but also facilitates upward removal. A plurality of meshes are arranged in an array on the filter press screen plate 8, and the mesh number is 400, which can ensure the discharge of wastewater and block sediment. The hydraulic cylinder 5 is installed on the top of the top plate 2, and the output end of the hydraulic cylinder 5 extends to the bottom of the top plate 2. The hydraulic cylinder 5 uses the MOB50*25 model of the MOB series, which can provide sufficient pressure for filter pressing. The pressing plate 6 is installed at the output end of the hydraulic cylinder 5, and the pressing plate 6 is slidably connected to the bracket 3. A pressing block 601 is installed on the lower surface of the pressing plate 6, and the shape of the pressing block 601 is adapted to the filter press screen plate 8. In addition, the shape of the pressing plate 6 corresponds to the pressing seat 42, and the part not corresponding to the pressing seat 42 is hollowed out to avoid interference with the components when pressing down. When in use, the filter press screen plate 8 is placed in the pressing cavity 43, the bottom mud is placed in the filter press screen plate 8, the hydraulic cylinder 5 is turned on to drive the pressing plate 6 to descend, and the pressing block 601 enters the filter press screen plate 8 to press the bottom mud.

[0058] In addition, a guide groove 10 is installed on the upper surface of the base 1, and the guide groove 10 corresponds to the lowest end position of the guide plate 45. The wastewater filtered out will fall on the guide groove 10 after being directional guided by the guide plate 45, thereby centrally guiding the wastewater and facilitating the collection and treatment of the wastewater.

[0059] like Figures 2 to 10 As shown, the impurity removal mechanism 7 is installed between the two frames 41, and the impurity removal mechanism 7 is used to remove impurities from the bottom mud in the pressing chamber 43. The impurity removal mechanism 7 includes a collecting plate 71, a mounting plate 72, a mounting rod 73, a first discharge port 74, a fixed shaft 75, a half gear 76, a connecting rod 77, a rotating plate 78, a flipping plate 79, a flipping shovel 710, a second discharge port 711, a gear ring 712, a connecting piece 713, a rotating rod 714, a first gear 715, a second gear 716, a rack 717, a slide 718, a mounting frame 719 and a scraper 720. There are several first discharge ports 74, which are respectively opened on the collecting plate 71, and the diameter thereof is 1 cm, which can prevent large pieces of debris from passing through. The mounting plate 72 is installed at one end of the collecting plate 71, and the mounting rod 73 is installed at the other end of the collecting plate 71. One end of the fixed shaft 75 is mounted on the mounting plate 72, the half gear 76 is rotatably mounted on the other end of the fixed shaft 75, the gear ring 712 is rotatably mounted on the fixed shaft 75, the rotating plate 78 is mounted on the gear ring 712, and the flip plate 79 is mounted on the rotating plate 78. The rotation of the gear ring 712 can drive the rotating plate 78 and the flip plate 79 to rotate synchronously. The collecting plate 71 and the flip plate 79 are both arc-shaped and coaxially arranged. The diameter of the circle where the collecting plate 71 is located is smaller than the diameter of the circle where the flip plate 79 is located. The lowest point of the collecting plate 71 is not lower than the highest point of the filter press plate 8. When in use, the collecting plate 71 will not contact the upper surface of the bottom mud. When the flip plate 79 rotates, the flip plate 79 will be inserted into the bottom mud and pass through the bottom mud. After the flip plate 79 rotates one circle, it will reset. There are several second discharge outlets 711, which are respectively opened on the flip plate 79. The width of the second discharge outlet 711 is 1 cm, which ensures that the mud and sand pass through and blocks large debris. The turning shovel 710 is installed on the turning plate 79. The turning shovel 710 is installed at a position away from the turning plate 79 so that it preferentially contacts the bottom mud when rotating. When the turning plate 79 is inserted into and passes through the bottom mud, the turning shovel 710 can block large debris and drive the debris to rotate. When the turning shovel 710 rotates to a position corresponding to the collecting plate 71, the debris will be turned over and dumped onto the collecting plate 71. Fig.14As shown, it is a schematic diagram of the dumping state. Among them, the width of the flipping shovel 710 is the difference between the radius of the circle where the collecting plate 71 is located and the radius of the circle where the flipping plate 79 is located, and the width value is the same as the depth value of the filter press plate 8, which ensures that the flipping plate 79 can be inserted into the deepest part of the bottom mud and fully screen the bottom mud. The connecting member 713 is fixedly installed on the fixed shaft 75, and a rotating rod 714 is rotatably installed on the connecting member 713. The first gear 715 and the second gear 716 are respectively installed at both ends of the rotating rod 714, and the first gear 715 is meshed with the gear ring 712. When the first gear 715 rotates, it can drive the gear ring 712 to rotate synchronously. The rack 717 is installed on the frame 41, and the rack 717 is meshed with the half gear 76. When the half gear 76 rotates, the part of its outer wall with teeth meshes with the rack 717, which will cause the half gear 76 to move laterally as a whole, and the diameter of the part of its outer wall without teeth is adapted to the position of the rack 717, as shown in FIG. Fig.15 As shown, when the portion without teeth contacts the rack 717, two adjacent teeth of the rack 717 will contact the portion without teeth of the half gear 76 at the same time, thereby limiting the half gear 76 laterally, so that the half gear 76 can only rotate but not move. At the same time, the half gear 76 begins to mesh with the second gear 716, so that the second gear 716 rotates. When the half gear 76 is out of mesh with the second gear 716, it will start to mesh with the rack 717 again, and limit the second gear 716 at the same time, so as to achieve the alternation of the lateral movement of the half gear 76 and the driving of the gear ring 712 to rotate, wherein the arc length of the teeth portion of the half gear 76 is the same as the circumference of the second gear 716, so as to ensure that the half gear 76 can drive the second gear 716 to rotate one circle each time. The connecting rod 77 is installed on the half gear 76, and there are two slideways 718, which are respectively opened on the opposite sides of the two frames 41, and the mounting rod 73 and the connecting rod 77 extend into the inner cavity of the two frames 41 through the two slideways 718 respectively. The two ends of the mounting frame 719 are respectively mounted on the mounting rod 73 and the connecting rod 77, wherein the mounting frame 719 is fixedly mounted on the mounting rod 73, and the mounting frame 719 is rotatably mounted on the connecting rod 77. The mounting frame 719 is slidably connected to the inner wall of the slideway 718. The mounting frame 719 and the slideway 718 cooperate with each other to keep the mounting frame 719 stable, and also ensure the stability of the half gear 76 and the connecting rod 77. The scraper 720 is mounted on the lower surface of the mounting frame 719, and the lower surface of the scraper 720 corresponds to the upper surface of the filter press screen plate 8. When the half gear 76 moves horizontally, it will synchronously pull the mounting frame 719 to move, thereby moving the scraper 720. The scraper 720 moves horizontally through the top of the filter press screen plate 8, and can scrape the upper surface of the bottom mud in the filter press screen plate 8 flat. If there is protruding excess bottom mud, the bottom mud will be pushed out of the filter press screen plate 8 along the moving direction of the scraper 720, thereby ensuring the stability of the force when the pressure plate 6 descends for filtering.

[0060] In this embodiment, the frame width of the pressing seat 42 is smaller than the distance the half gear 76 moves each time it engages with the rack 717, ensuring that after the last part of the bottom mud is removed and screened, the impurity removal mechanism 7 moves as a whole again, allowing the collecting plate 71 and the flip plate 79 to leave the top of the pressing seat 72.

[0061] In addition, the turning shovel 710 in this embodiment is composed of a plurality of equidistantly arranged shovel teeth with a spacing of 1 cm, which can not only block and support large pieces of debris, but also help clean up long strips of debris such as sink debris.

[0062] The driving mechanism 9 is installed in the frame 41 and is used to drive the impurity removal mechanism 7 to operate. The driving mechanism 9 includes a worm 91, a motor 92, a slide bar 93 and a worm wheel 94. The worm 91 is rotatably installed in the frame 41 near the side of the semi-gear 76. The worm wheel 94 is installed at an end of the connecting rod 77 away from the semi-gear 76. The worm wheel 94 is meshed and connected with the worm 91. When the worm 91 rotates, the worm wheel 94 can be driven to rotate synchronously. The worm wheel 94 and the worm 91 adopt a model with a self-locking characteristic. The transmission system formed by them has a self-locking property. When the worm 91 stops rotating, the worm wheel 94 is locked and will not rotate. The motor 92 is installed on the frame 41. The output end of the motor 92 extends into the inner cavity of the frame 41 and is connected to the worm 91. Turning on the motor 92 can drive the worm 91 to rotate. The model of the motor 92 is a JGY370 series motor. Its output end can be locked at any position. After shutting down, locking the output end can ensure that the worm 91 will not rotate. The slide rod 93 is installed in another frame 41, and the slide rod 93 is arranged parallel to the worm gear 91. The mounting rod 73 is slidably connected to the slide rod 93. Through the limitation of the slide rod 93, it is ensured that the mounting rod 73 and the collecting plate 71 can only move in the same axial direction as the slide rod 93 and will not rotate.

[0063] The specific working principle of this embodiment is as follows:

[0064] Place the filter press screen plate 8 in the pressing chamber 43, then put the sludge to be filtered into the filter press screen plate 8, then turn on the motor 92 to drive the worm 91 to rotate, so that the worm wheel 94, the connecting rod 77 and the half gear 76 rotate together, and the half gear 76 begins to mesh with the rack 717, so that the half gear 76, the collecting plate 71 and the mounting rod 73 move along the axial direction of the worm 91, and the impurity removal mechanism 7 moves as a whole. At this time, the second gear 716 is stationary due to the limitation of the half gear 76 without teeth. When the half gear 76 is disengaged from the meshing of the rack 717, the half gear 76, the collecting plate 71 and the mounting rod 73 move to the top of the filter press plate 8 and stop moving. At this time, the half gear 76 begins to mesh with the second gear 716 and drives the second gear 716 to rotate. At this time, the second gear 716, the rotating rod 714 and the first gear 715 rotate synchronously, and drive the gear ring 712 to rotate in the same direction as the half gear 76, thereby driving the rotating plate 78 and the flip plate 79 to drive. The flip plate 79 rotates and inserts into the bottom mud to screen the large debris therein, and uses the flip shovel 710 to support and flip the debris so that the debris falls on the collecting plate 71. When the half gear 76 is disengaged from the meshing of the second gear 716, the flip plate 79 rotates one circle and resets. At this time, the half gear 76 is meshed with the rack 717 again, and the half gear 76, the collecting plate 71 and the mounting rod 73 continue to move, and the impurity removal mechanism 7 continues to move as a whole.

[0065] As the impurity removal mechanism 7 moves as a whole, the scraper 720 will scrape the upper surface of the sludge in the filter press screen plate 8 flat and push out the excess sludge laterally.

[0066] As shown in the above steps, the movement of the impurity removal mechanism 7 and the screening work are carried out alternately and continuously until the last part of the bottom mud is screened, the half gear 76, the collecting plate 71 and the mounting rod 73 move to the outside of the filter press plate 8, and the impurity removal mechanism 7 continues to move a certain distance, so that the scraper 720 leaves the pressing seat 42 and the motor 92 can be turned off.

[0067] The hydraulic cylinder 5 is turned on to drive the pressing plate 6 to descend, and the pressing block 601 is used to squeeze the bottom mud in the filter press mesh plate 8 to discharge the waste water. Then the pressing plate 6 is reset to complete the filter press work.

[0068] This embodiment can not only filter to obtain sediment samples, but also automatically screen and clean large debris in the sediment and automatically transfer the debris. At the same time, it can automatically scrape the sediment to be filtered to keep it flat, ensuring uniform force during filtration while preventing large debris from damaging the equipment.

[0069] Embodiment 2:

[0070] like Fig.11 , Fig.12 and Fig.13As shown, a port channel sediment sample filter press device is provided, and the difference between this embodiment and embodiment 1 is that the port channel sediment sample filter press device has a plurality of filter press units. The plurality of filter press units are equidistantly installed on the bracket 3, and the plurality of filter press units are connected by a connecting rod assembly 11. Through the linkage of the connecting rod assembly 11, it is ensured that after the pressure plate 6 in the topmost filter press unit is subjected to the force of the hydraulic cylinder 5, the pressure plates 6 in the remaining filter press units can be synchronously lowered, thereby realizing the synchronous operation of the plurality of filter press units.

[0071] The connecting rod assembly 11 includes a first rotating rod 111, a second rotating rod 112 and a cross connecting rod 113. There are a plurality of cross connecting rods 113, each of which is composed of two single rods connected in rotation in the middle, and the rotation connection of the two single rods forms a first intersection 116. Two cross connecting rods 113 adjacent to each other are connected in rotation. The first rotating rod 111 and the second rotating rod 112 are respectively composed of two independent rods connected in rotation, and the rotation connection is located at the end of the independent rods. The connection of the two independent rods in the first rotating rod 111 forms a second intersection 114, and the connection of the two independent rods in the second rotating rod 112 forms a third intersection 115. The first rotating rod 111 and the second rotating rod 112 are respectively connected in rotation to the cross connecting rods 113 at the top and bottom. The first rotating rod 111 and the plurality of cross connecting rods 113 are respectively connected to the plurality of pressing plates 6, wherein the second intersection 114 is connected to the pressing plate 6 in the topmost filter press unit, the plurality of first intersections 116 are respectively connected to the pressing plates 6 in the remaining filter press units, and the third intersection 115 is connected to the base 1. When the pressing plate 6 in the top filter press unit descends, the first rotating rod 111, the second rotating rod 112 and the cross connecting rod 113 will respectively start to rotate, so that the pressing plates 6 in each filter press unit will descend synchronously, and the descending distance and speed are the same, so as to ensure that each filter press unit starts the filtration work synchronously and is subjected to equal force.

[0072] In this embodiment, there are two connecting rod assemblies 11, which are symmetrically arranged on the front and rear sides of the filter press unit, so as to further ensure that the overall force of the equipment is balanced and stable.

[0073] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
