Description

Technical Field

[0001] This application relates to the technical field of wastewater and waste residue separation equipment, and in particular to a separation equipment for concrete wastewater and waste residue. Background Technology

[0002] Concrete construction generates a large amount of wastewater containing waste residue, which mainly consists of sand and gravel particles of varying sizes. Direct discharge of this wastewater not only wastes sand and gravel resources but also pollutes water bodies and soil, falling under the categories of water pollution and solid waste pollution, which does not meet environmental protection requirements. Therefore, specialized environmental protection equipment for water and solid waste pollution treatment is needed to separate and recycle concrete wastewater and waste residue. Existing separation equipment mostly uses single screening or sedimentation methods, which suffer from low separation efficiency and poor resource recovery rates. A single vibrating screen can only roughly separate coarse and fine sand, making it difficult to handle mixtures containing large amounts of wastewater, and fine sand is easily lost with the wastewater. Sedimentation methods have long processing cycles and require a large area, making them unsuitable for the dynamic treatment needs of construction sites. Although some equipment combines screening and sedimentation, it lacks a continuous feeding and grading separation structure, making it easy for sand-containing wastewater discharged from the fine sand box to undergo secondary mixing, and the waste residue channel to become clogged.

[0003] Patent (202410590299.4) discloses a wastewater recycling device for concrete production, including a treatment tank. A centrifugal separation component is rotatably installed inside the treatment tank, and a sand accumulation component is fixedly installed at the end of the centrifugal separation component. The above patent uses the rotation of the centrifugal component to move the wastewater mixture discharged into the centrifugal tube to the outside under the action of centrifugal force, thereby achieving the separation of wastewater and waste residue. However, the above separation method is only limited to separating large particulate matter. For impurities such as wood chips, plastic particles and grease, the above separation method cannot effectively separate them, resulting in poor separation effect of wastewater and waste residue.

[0004] Regarding the aforementioned technologies, the inventors believe that they suffer from poor separation of waste liquid and waste residue. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this application provides a separation device for concrete wastewater and waste residue.

[0006] This application provides a separation device for concrete wastewater and waste residue, which adopts the following technical solution: A separation device for concrete wastewater and waste residue includes a vibrating screen, a fine sand box, a coarse sand box, and a separation assembly. The vibrating screen has a fine sand outlet and a coarse sand outlet. The fine sand box is located directly below the fine sand outlet. The coarse sand box is located directly below the coarse sand outlet. The separation assembly includes an inner box and an outer box. The inner box is located directly below the fine sand box. The outer box is fitted over the outer side of the inner box. A waste residue channel is provided between the inner box and the outer box. An annular float is vertically slidably disposed inside the outer box. The annular float is used to close the inner box and the waste residue channel. A spiral feeding unit connects the inner box and the fine sand box.

[0007] By adopting the above technical solution, the vibrating screen can separate coarse sand and fine sand. The separated fine sand and wastewater enter the fine sand box. The fine sand and waste liquid are then conveyed into the inner box through the screw feeding unit. As the amount of waste liquid increases, the fine sand settles at the bottom of the inner box, while the sawdust, plastic particles, and grease in the fine sand float on the surface. When the liquid touches and lifts the annular float, the annular float connects the waste slag channel and the inner box, allowing the sawdust, plastic particles, and grease floating on the waste liquid to flow into the waste slag channel. This improves the treatment accuracy of the waste liquid and saves manpower.

[0008] Preferably, the spiral feeding unit includes a feeding pipe and a spiral rod; the top of the feeding pipe is connected to the fine sand outlet; the bottom of the feeding pipe penetrates downward through the top wall of the outer casing and is located at the bottom of the inner casing; the spiral rod is rotatably disposed inside the feeding pipe.

[0009] Preferably, the waste residue channel is equipped with an annular cloth bag filter.

[0010] By adopting the above technical solution, the annular bag filter element can filter wastewater, wood chips, plastic particles and grease, and store them in the waste residue channel.

[0011] Preferably, the top of the inner box is provided with an elastic telescopic ring; multiple sets of adjustment modules are rotatably arranged inside the inner box; the multiple sets of adjustment modules are evenly distributed along the circumference of the inner box; each set of adjustment modules has an elastic degree of freedom to rotate towards the top wall of the receiving block; multiple receiving blocks are provided on the elastic telescopic ring; the multiple receiving blocks correspond one-to-one with the multiple sets of adjustment modules; after the adjustment module rotates, one end of it abuts against the top wall of the receiving block.

[0012] By adopting the above technical solution, the adjustment module can squeeze the receiving block on the elastic telescopic ring after rotation, and push the elastic telescopic ring downward, thereby expanding the connection between the inner box and the waste slag channel, making it easier for wood chips, plastic particles and grease to enter the waste slag channel.

[0013] Preferably, a plurality of limiting blocks are provided on the bottom wall of the annular float; the plurality of limiting blocks correspond one-to-one with a plurality of sets of adjustment modules; the adjustment module abuts against the side wall of the limiting block opposite to the outer casing.

[0014] By adopting the above technical solution, when the annular float is not moved, the adjustment module can abut against the limiting block. On the one hand, it can fix the annular float on the outer box, and on the other hand, it can prevent the adjustment module from rotating and squeezing the receiving block.

[0015] Preferably, the adjustment module includes a counterweight cam and a first tension spring; the counterweight cam is rotatably mounted on the inner housing; the counterweight end of the counterweight cam abuts against the limiting block or the receiving block; one end of the first tension spring is connected to the counterweight end of the counterweight cam; the other end is connected to the inner housing; the first tension spring is used to provide a force that moves the counterweight end of the counterweight cam away from the receiving block.

[0016] By adopting the above technical solution, the counterweight end of the counterweight cam automatically squeezes the limiting block to maintain the stability of the overall structure. When the wastewater lifts the annular float, the counterweight cam disengages from the limiting block and rotates towards the receiving block under the action of gravity, thereby expanding the connection between the inner box and the waste slag channel, improving work efficiency, and achieving the self-cleaning effect of wood chips, plastic particles and grease in the wastewater.

[0017] Preferably, a compression unit is slidably arranged vertically inside the waste residue channel; the compression unit is located above the annular filter bag.

[0018] Preferably, the extrusion unit includes an extrusion ring plate, an elastic element, and a plurality of extrusion rods; the extrusion ring plate is slidably disposed vertically within the waste slag channel; a plurality of through holes are uniformly formed along the circumference of the extrusion ring plate; one end of each of the plurality of extrusion rods is rotatably disposed on the inner housing; the other end of each of the plurality of extrusion rods is provided with a counterweight ball, and is inclined toward the inner housing; the plurality of counterweight balls correspond one-to-one with the plurality of through holes; the top end of the elastic element is connected to the extrusion ring plate, and the bottom end is connected to the outer housing.

[0019] By adopting the above technical solution, the upward-flowing waste liquid can push the annular drive plate upward, and transmit it to the squeezing rod through multiple drive rods, thereby pushing the squeezing rod to rotate. This causes the counterweight ball to block the through hole and pushes the squeezing ring plate downward, so that the impurities are squeezed into blocks between the squeezing ring plate and the annular filter bag. The blocky impurities are easy to clean.

[0020] Preferably, the extrusion unit further includes an annular drive plate, multiple drive rods, and multiple sealing plates; the annular drive plate is slidably disposed vertically within the inner housing; multiple vertical grooves are formed on the peripheral wall of the inner housing; the multiple drive rods are slidably disposed one-to-one within the multiple vertical grooves; one end of each drive rod is connected to the annular drive plate; the other end of each drive rod passes through the vertical groove and abuts against the side wall of the extrusion rod; the multiple sealing plates are connected to the multiple drive rods; and the multiple sealing plates correspond one-to-one with the multiple vertical grooves.

[0021] By adopting the above technical solution, the upward-flowing waste liquid can push the annular drive plate upward, and transmit it to the extrusion rod through multiple drive rods, which in turn rotate the extrusion rod to the outside of the inner box; thus, the counterweight ball can block the through hole and press down the extrusion ring plate, achieving the effect of automatic filtration and extrusion into blocks of waste residue in the waste residue channel.

[0022] Preferably, a second tension spring is connected between the top of the compression rod and the outer wall of the inner box.

[0023] By adopting the above technical solution, the second tension spring can work with the elastic element to pull the extrusion rod towards the inner box after the extrusion rod rotates, thereby causing the annular drive plate to move downwards. This cycle repeats, causing the annular drive plate to move vertically back and forth within the inner box, thus achieving the effect of stirring the waste liquid. It also causes the counterweight ball to continuously press down on the extrusion ring plate, gradually squeezing the waste residue layer by layer onto the annular filter bag, thereby improving the separation effect of waste residue and wastewater.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The vibrating screen can separate coarse sand and fine sand. The separated fine sand and wastewater enter the fine sand tank. The fine sand and waste liquid are then conveyed into the inner tank through the screw feeding unit. As the amount of waste liquid increases, the fine sand settles at the bottom of the inner tank, while the sawdust, plastic particles, and grease in the fine sand float on the surface. When the liquid touches and lifts the annular float, the annular float connects the waste slag channel and the inner tank, allowing the sawdust, plastic particles, and grease floating on the waste liquid to flow into the waste slag channel. This improves the treatment accuracy of the waste liquid and saves manpower.

[0025] 2. By setting the counterweight cam to automatically squeeze the limiting block, the overall structure is kept stable; when the wastewater lifts the annular float, the counterweight cam disengages from the limiting block and rotates towards the receiving block under the action of gravity, thereby expanding the connection between the inner box and the waste slag channel, improving work efficiency, and achieving the self-cleaning effect of wood chips, plastic particles and grease in the wastewater.

[0026] 3. The upward flow of waste liquid pushes the annular drive plate upward, which is then transmitted to the extrusion rod via multiple drive rods. This causes the extrusion rod to rotate outward from the inner chamber. The counterweight ball then blocks the through-hole and presses down on the extrusion ring plate, achieving automatic filtration and compression of waste residue into blocks within the waste residue channel. The second tension spring, in conjunction with the elastic element, pulls the extrusion rod towards the inner chamber after it rotates, causing the annular drive plate to move downward. This cycle repeats, causing the annular drive plate to move vertically back and forth within the inner chamber, thus agitating the waste liquid. Furthermore, the counterweight ball continuously presses down on the extrusion ring plate, gradually compressing the waste residue layer by layer onto the annular filter bag, improving the separation effect between waste residue and wastewater.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses a separation device for concrete wastewater and waste residue. (Refer to...) Figure 1-2 The system includes a vibrating screen 11, a fine sand box 12, a coarse sand box 13, and a separation component 2. The vibrating screen 11 has a fine sand outlet and a coarse sand outlet. The fine sand box 12 is located directly below the fine sand outlet. The coarse sand box 13 is located directly below the coarse sand outlet. The vibrating screen 11 can discharge large particles of waste residue from wastewater and waste residue into the coarse sand box 13. Wastewater and fine sand are discharged into the fine sand box 12. The separation component 2 includes an inner box 21 and an outer box 22. The inner box 21 is located directly below the fine sand box 12. The outer box 22 is fitted outside the inner box 21. A waste residue channel 23 is provided between the inner box 21 and the outer box 22. An annular float 3 is vertically slidably arranged inside the outer box 22. The annular float 3 is used to close the inner box 21 and the waste residue channel 23. When liquid touches and lifts the annular float 22, the float 3 is used to close the inner box 21 and the waste residue channel 23. After the annular float 3, the annular float 3 connects the waste slag channel 23 and the inner box 21, allowing the wood chips, plastic particles and grease floating on the waste liquid to flow into the waste slag channel 23; the waste slag channel 23 is equipped with an annular bag filter element 231; the annular bag filter element 231 can filter the waste slag and allow the water to flow downwards; the waste slag channel 23 is vertically slidably equipped with an extrusion unit 7; the extrusion unit 7 is located above the annular bag filter element; the inner box 21 and the fine sand box 12 are connected by a spiral feeding unit 4; the spiral feeding unit 4 includes a feed pipe 41 and a spiral rod 42; the top of the feed pipe 41 is connected to the fine sand outlet; the bottom of the feed pipe 41 penetrates downwards through the top wall of the outer box 22 and is located at the bottom of the inner box 21; the spiral rod 42 is rotatably installed in the feed pipe 41.

[0035] An elastic telescopic ring 5 is provided on the top of the inner box 21; multiple sets of adjustment modules 6 are rotatably arranged inside the inner box 21; the multiple sets of adjustment modules 6 are evenly distributed along the circumference of the inner box 21; each set of adjustment modules 6 has an elastic degree of freedom to rotate towards the top wall of the receiving block 51; multiple receiving blocks 51 are provided on the elastic telescopic ring 5; the multiple receiving blocks 51 correspond one-to-one with the multiple sets of adjustment modules 6; after the adjustment module 6 rotates, one end of it abuts against the top wall of the receiving block 51; multiple limiting blocks 31 are provided on the bottom wall of the annular float 3; the multiple limiting blocks 31 correspond one-to-one with the multiple sets of adjustment modules 6; the adjustment module 6 abuts against the side wall of the limiting block 31 opposite to the outer box 22.

[0036] Reference Figure 3 Furthermore, the adjustment module 6 includes a counterweight cam 61 and a first tension spring 62; the counterweight cam 61 is rotatably mounted on the inner housing 21; the counterweight end of the counterweight cam 61 abuts against the limiting block 31 or the receiving block 51; one end of the first tension spring 62 is connected to the counterweight end of the counterweight cam 61; the other end is connected to the inner housing 21; the first tension spring 62 is used to provide a force that moves the counterweight end of the counterweight cam 61 away from the receiving block 51.

[0037] Under normal circumstances, the counterweight end of the counterweight cam 61 is offset towards the limiting block 31 and pressed against the limiting block 31; when the annular float 3 is lifted by the waste liquid, the counterweight cam 61 loses the obstruction of the limiting block 31 and rotates towards the receiving block 51 under the gravity of its counterweight end, and presses the elastic telescopic ring 5 down, expanding the connection between the inner box 21 and the waste slag channel 23.

[0038] Reference Figure 4 and Figure 5 The extrusion unit 7 includes an extrusion ring plate 71, an elastic element 72, an annular drive plate 75, multiple drive rods 76, multiple sealing plates 77, and multiple extrusion rods 73. The extrusion ring plate 71 is vertically slidably disposed within the waste residue channel 23. Multiple through holes 711 are evenly provided on the extrusion ring plate 71 along its circumference. Under normal circumstances, the extrusion rods 73 are deflected towards the inner box 21, and waste liquid and waste residue flow downward through the through holes 711 of the extrusion ring plate 71. One end of each of the multiple extrusion rods 73 is rotatably disposed on the inner box 21. The other end of each of the multiple extrusion rods 73 is provided with a counterweight ball 74, which is inclined towards the inner box 21. Each of the multiple counterweight balls 74 corresponds to one of the multiple through holes 711. The elastic element 72 is a spring; the top end of the elastic element 72 is connected to the extrusion ring plate 71, and the bottom end is connected to the outer housing 22; the annular drive plate 75 is vertically slidably disposed in the inner housing 21; multiple vertical grooves are provided on the peripheral wall of the inner housing 21; multiple drive rods 76 are slidably disposed in the multiple vertical grooves respectively; one end of the multiple drive rods 76 is connected to the annular drive plate 75; the other end of the multiple drive rods 76 passes through the vertical grooves respectively and abuts against the side wall of the extrusion rod 73; multiple sealing plates 77 are connected to the multiple drive rods 76 respectively; the multiple sealing plates 77 correspond to the multiple vertical grooves respectively; a second tension spring is connected between the top end of the extrusion rod 73 and the outer wall of the inner housing 21.

[0039] During operation, the upward-flowing waste liquid pushes the annular drive plate 75 upward, and transmits it to multiple extrusion rods 73 via multiple drive rods 76, causing the extrusion rods 73 to rotate outward from the inner chamber 21. This allows the counterweight ball 74 to block the through hole 711 and press down on the extrusion ring plate 71. The second tension spring, in conjunction with the elastic element 72, pulls the extrusion rod 73 towards the inner chamber 21 after the extrusion rod 73 rotates, thereby causing the annular drive plate 75 to move downward. This cycle repeats, causing the annular drive plate 75 to move vertically back and forth within the inner chamber 21, thus achieving the effect of stirring the waste liquid. It also causes the counterweight ball 74 to continuously press down on the extrusion ring plate 71, gradually extruding the waste residue layer by layer onto the annular filter bag 231. The waste residue needs to be extruded multiple times to form a block, at which point the annular filter bag 231 needs to be replaced, and the blocky waste residue needs to be cleaned and discharged.

[0040] The working principle of the concrete wastewater and waste residue separation device in this application is as follows: After the equipment is started, the concrete wastewater and waste residue are first fed into the vibrating screen 11. The vibrating screen 11 performs preliminary classification of the mixture through vibration and achieves separation by utilizing the difference in the mesh size of the screen: large particles of waste residue cannot pass through the screen and are eventually discharged from the coarse sand outlet and collected in the coarse sand box 13 directly below; while fine sand and wastewater can pass through the screen and are discharged from the fine sand outlet and enter the corresponding fine sand box 12 for temporary storage, completing the first solid-liquid classification and separation.

[0041] The screw feed unit 4 conveys the fine sand and wastewater in the fine sand box 12 to the inner box 21 through the connected screw feed unit 4; the top of the feed pipe 41 of this unit is connected to the fine sand outlet and the bottom extends to the bottom of the inner box 21. When the screw rod 42 rotates in the feed pipe 41, it will generate a continuous pushing force, which will stably and evenly convey the fine sand and wastewater in the fine sand box 12 to the inner box 21, avoiding material accumulation and blockage, and also reducing the premature deposition of fine sand during the conveying process.

[0042] In the initial state, the counterweight end of the counterweight cam 61 in the adjustment module 6, under the tension of the first tension spring 62, shifts towards the limiting block 31 on the bottom wall of the annular float 3 and presses against the limiting block 31. At this time, the annular float 3 closes the inner box 21 and the waste slag channel 23 to prevent premature material flow. When the waste liquid level in the inner box 21 gradually rises and touches the annular float 3, buoyancy will push up the annular float 3, and the annular float 3 will drive the limiting block 31 to move upward synchronously. At this time, the counterweight cam 61 loses the obstruction of the limiting block 31, and its counterweight end rotates towards the receiving block 51 on the elastic telescopic ring 5 under its own weight and presses against the receiving block 51, causing the elastic telescopic ring 5 to move downward, thereby widening the connection between the inner box 21 and the waste slag channel 23. The wood chips, plastic particles, grease and other impurities floating on the surface of the waste liquid then flow into the waste slag channel 23 through the widened connection.

[0043] Impurities and some waste liquid flowing into the waste slag channel 23 pass through the annular bag filter 231. The annular bag filter 231 can intercept waste slag such as wood chips and plastic particles, allowing the waste liquid to flow smoothly downwards, achieving secondary separation of waste slag and waste liquid. On the other hand, the extrusion unit 7 will operate simultaneously to complete the separation of fine sand and compaction of waste slag. The specific process is as follows: Initially, the extrusion rod 73 is tilted towards the inner chamber 21, and the counterweight ball 74 does not block the through hole 711 on the extrusion ring plate 71, allowing waste liquid and fine sand to flow smoothly downwards through the through hole 711 to the annular bag filter element 231. When the waste liquid flows upwards, it pushes the annular drive plate 75 inside the inner chamber 21 to move upwards. The annular drive plate 75 drives multiple drive rods 76 to move upwards synchronously along the vertical slide groove. The drive rods 76 then push the extrusion rod 73, which is in contact with them, to rotate outwards. After the extrusion rod 73 rotates, the counterweight ball 74 at its end just blocks the corresponding through hole 711. At the same time, the rotation of the extrusion rod 73 will press down the extrusion ring plate 71. When the extrusion ring plate 71 moves downwards, it will squeeze the waste residue on the annular bag filter element 231, compacting the waste residue layer by layer. Then, under the action of the tension of the second tension spring and the elastic restoring force of the elastic element 72, the extrusion rod 73 is pulled back and tilted towards the inner chamber 21, and the annular drive plate 75 also moves downwards accordingly.

[0044] This process repeats itself, allowing the annular drive plate 75 to move up and down to stir the waste liquid, preventing the sedimentation of fine sand and impurities. It also continuously compacts the waste residue by squeezing the annular plate 71, improving the filtration efficiency of the annular bag filter element 231 for the waste liquid, and ultimately achieving complete separation of fine sand, floating impurities and wastewater.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
