[0040] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0041] Please refer to the following: Figures 1 to 7The present invention provides a waste treatment device for a mixing plant. The waste treatment device includes a housing 1, a first screen cylinder 2, and a second screen cylinder 3. The first screen cylinder 2 is rotatably disposed within the housing 1. One end of the first screen cylinder 2 is a feed inlet 21, and the other end is a stone discharge outlet 22. The diameter of the screen holes in the first screen cylinder 2 is smaller than the diameter of the stones but larger than the diameter of the fine sand. The first screen cylinder 2 contains a first spray pipe 4, one end of which extends out of the first screen cylinder 2 and connects to the housing 1. The second screen cylinder 3 is rotatably disposed within the housing 1. The second screen cylinder 3 is fitted onto the first screen cylinder 2 and connects to the first screen cylinder 2. The screen cylinder 2 rotates synchronously; the screen hole diameter of the second screen cylinder 3 is smaller than the fine sand diameter; the same side end of the second screen cylinder 3 and the stone discharge end 22 is the fine sand discharge end 31; wherein, the stone discharge end 22 of the first screen cylinder 2 protrudes through one side of the box body 1; the fine sand discharge end 31 of the second screen cylinder 3 is located inside the box body 1, and the side wall of the box body 1 has a discharge structure 5 for receiving fine sand, which extends out of one side of the box body 1; the box body 1 has a collection chamber 11 for receiving slurry; the top of the box body 1 has a cover plate 12, which is bolted to the box body 1. A guide pipe (not shown in the figure) can be installed on the box body 1, which is connected to the collection chamber 11, and the other end of the guide pipe is connected to the sewage treatment equipment; the slurry in the collection chamber 11 can flow into the sewage treatment equipment through the guide pipe; a water pump can also be installed on the guide pipe to provide power to the slurry. An inclined plate 14 can be installed below the discharge end of the first screen cylinder 2 in the box body 1. The inclined plate 14 can guide the stones falling from the first screen cylinder 2.
[0042] This invention provides a waste treatment device for a concrete mixing plant. Compared with the prior art, when there is unused concrete in the mixing plant, the wet concrete is fed into a first screen cylinder 2. Water can be used to wash the wet concrete into the first screen cylinder 2. The first screen cylinder 2 is rotatably connected to the housing 1, and the first spray pipe 4 sprays water onto the wet concrete in the first screen cylinder 2 to make the concrete lose its stickiness. The rotation of the first screen cylinder 2 can screen stones and fine sand. The stones can be discharged from the stone discharge end 22 of the first screen cylinder 2. The fine sand falls into the second screen cylinder 3 after passing through the screen holes of the first screen cylinder 2. The rotation of the second screen cylinder 3 can separate the fine sand and slurry. The slurry falls into the collection chamber 11 below, and the fine sand can be discharged from the fine sand discharge end 31. With the above-mentioned settings, the remaining concrete in the mixing plant can be treated, reducing the occurrence of concrete solidification in the mixing plant.
[0043] For example, both the first screen cylinder 2 and the second screen cylinder 3 are inclinedly arranged inside the housing 1. The feed end 21 of the first screen cylinder 2 is the high end, and the stone discharge end 22 of the first screen cylinder 2 is the low end. The two sides of the housing 1 connected to the first screen cylinder 2 are separate side plates. The side plates are bolted to the housing 1, and the side plates are sealed to the housing 1. With the above arrangement, it is convenient to replace the first screen cylinder 2 and the second screen cylinder 3 when they are damaged.
[0044] It should be noted that the portion of the first screen cylinder 2 located outside the box body 1 has no screen holes, while the portion of the first screen cylinder 2 located inside the box body 1 has screen holes. The purpose of the above arrangement is to reduce the amount of slurry and fine sand falling outside the box body 1 when wet concrete is fed into the feed end 21 of the first screen cylinder 2.
[0045] In some embodiments, such as Figures 1 to 7 As shown, the discharge structure 5 includes a collection box 51, a discharge plate 52, and a connecting structure 53; the collection box 51 has an opening 511 on one side for insertion and cooperation with the second screen cylinder 3, and a through hole on the other side for insertion and cooperation with the first screen cylinder 2; the bottom of the collection box 51 has an inclined guide plate 54, and the collection box 51 has a first clearance opening 512 for material to slide down between the through hole and the guide plate 54; the discharge plate 52 is inclinedly arranged on the side wall of the box body 1; the side of the box body 1... The wall has a second clearance opening 13 for material to slide out; the discharge plate 52 is slidably engaged with the box body 1; the connecting structure 53 is used to connect the collection box 51 and the discharge plate 52; wherein, when the collection box 51 and the discharge plate 52 are set separately, the collection box 51 can slide along the axis of the first screen cylinder 2, and the discharge plate 52 is slidably engaged with the box body 1 in the inclined direction; when the connecting structure 53 connects the collection box 51 and the discharge plate 52, it can restrict the sliding of the collection box 51 and the discharge plate 52.
[0046] For example, the discharge plate 52 is lower than the guide plate 54, and a portion of the top of the discharge plate 52 contacts the bottom of the guide plate 54; when the second screen cylinder 3 discharges material, the fine sand first falls into the collection box 51, then falls onto the guide plate 54, and finally slides out from the discharge plate 52; by providing a first clearance opening 512 on the collection box 51, the fine sand can slide out of the collection box 51; by providing a second clearance opening 13 on the box body 1, the fine sand can slide out of the box body 1.
[0047] For example, a receiving box or a conveyor belt is provided outside the box body 1 at the position of the feed end 21 of the first screen cylinder 2 and the position of the discharge plate 52, respectively, so as to collect or transport the screened stones and fine sand.
[0048] It should be noted that when the connecting structure 53 is not connected to the collecting box 51 and the discharge plate 52, the collecting box 51 can slide along the axis of the first screen cylinder 2, and the discharge plate 52 can slide along the inclined direction. When the connecting structure 53 connects the collecting box 51 and the discharge plate 52, since the sliding direction of the collecting box 51 and the sliding direction of the discharge plate 52 have an angle, after being fixed by the connecting structure 53, the collecting box 51 cannot slide along the axis of the first screen cylinder 2, and the discharge plate 52 cannot slide along the inclined direction. That is, the sliding of the discharge plate 52 and the collecting box 51 can be restricted, so that the fine sand in the second screen cylinder 3 is discharged from the collecting box 51 and the discharge plate 52 from the box body 1.
[0049] In addition, after the collection box 51 and the discharge plate 52 are connected by the connecting structure 53, the collection box 51 will not rotate with the first screen cylinder 2.
[0050] In some embodiments, such as Figures 1 to 7 As shown, the guide plate 54 has first side plates 541 on both sides, and the discharge plate 52 has second side plates 521 on both sides. The outer side wall of the first side plate 541 can contact the inner side wall of the second side plate 521. The connecting structure 53 includes a clamping plate 531, a clamping post 532, and an elastic member 533. One end of the clamping plate 531 is hinged to the outer side of the second side plate 521. The other end of the clamping plate 531 has a clamping groove 534. The clamping post 532 is connected to the outer side of the first side plate 541. The second side plate 521 has a sliding groove 522 for sliding engagement of the clamping post 532. One end of the elastic member 533 is connected to the outer side of the second side plate 521, and the other end is connected to the clamping plate 531. Under the elastic force of the elastic member 533, the clamping groove 534 can engage with the clamping post 532 to fix the position of the collection box 51 and the discharge plate 52.
[0051] For example, after the locking plate 531 and the locking post 532 are engaged, the elastic member 533 can provide a downward elastic force to the locking plate 531, so that the locking plate 531 provides downward pressure to the locking post 532, thereby reducing the occurrence of the locking post 532 automatically separating from the locking plate 531.
[0052] It should be noted that by sliding the discharge plate 52, the locking post 532 on the first side plate 541 can slide into the groove 522 of the second side plate 521. Then, by engaging the locking post 532 with the locking groove 534 on the locking plate 531, the locking post 532 can be restricted within the locking groove 534, thereby fixing the collection box 51 and the discharge plate 52 together.
[0053] In addition, the two second side plates 521 of the discharge plate 52 are each provided with a connecting structure 53.
[0054] In some embodiments, such as Figures 1 to 7As shown, the end of the card plate 531 corresponding to the opening 511 of the slide groove 522 has a guide slope 535, which is used to contact the outer peripheral wall of the card post 532; a positioning part 536 is fixedly provided on the outer side of the second side plate 521, which is used to contact the bottom of the card plate 531; through the above arrangement, the lowest position of the card plate 531 can be limited. For example, the elastic element 533 includes a spring, one end of which is connected to the bottom of the card plate 531, and the other end of which is connected to the outer wall of the second side plate 521.
[0055] It should be noted that by providing a guide slope 535 on the clamping plate 531, the sliding of the discharge plate 52 allows the clamping post 532 to slide to the designated position of the groove 522, and the clamping groove 534 on the clamping plate 531 can engage with the clamping post 532. Specifically, when the clamping post 532 contacts the guide slope 535 of the clamping plate 531, the clamping post 532 can push the clamping plate 531 upward; when the clamping post 532 moves to the position corresponding to the clamping groove 534, the clamping plate 531 rotates downward under the elastic force of the elastic member 533, allowing the clamping groove 534 to engage with the clamping post 532.
[0056] In some embodiments, such as Figures 1 to 7 As shown, the top of the card plate 531 has a threaded hole at the position corresponding to the card slot 534, and the card plate 531 is threaded with a push bolt 537; when disassembling the collection box 51 and the discharge plate 52, the push bolt 537 can keep the card post 532 in a state separated from the card slot 534.
[0057] It should be noted that when it is necessary to separate the collection box 51 and the discharge plate 52, rotating the clamping plate 531 upwards can separate the clamping groove 534 from the clamping post 532. By rotating the push bolt 537, the threaded end of the push bolt 537 can be inserted into the opening 511 of the clamping groove 534, thereby preventing the clamping groove 534 from jamming with the clamping post 532. With the above settings, the clamping plates 531 on both sides of the discharge plate 52 can be separated from the clamping post 532. Then, by sliding the discharge plate 52 downwards, the discharge plate 52 can be separated from the collection box 51, reducing the difficulty of disassembly.
[0058] In some embodiments, such as Figures 1 to 7 As shown, the feed end 21 of the first screen cylinder 2 is located outside the box body 1, and the side wall of the feed end 21 of the first screen cylinder 2 is thickened; the outer peripheral wall of the feed end 21 of the first screen cylinder 2 has several toothed grooves 23, and a gear 6 is rotatably provided on the box body 1, and the gear 6 meshes with the toothed grooves 23 on the first screen cylinder 2.
[0059] It should be noted that the housing 1 has a drive motor (not shown in the figure) for driving the gear 6 to rotate, and the output shaft of the drive motor is connected to the gear 6; both the drive motor and the gear 6 can be removed from the housing 1, thus facilitating the removal of the first screen cylinder 2 from the housing 1. By providing several toothed grooves 23 on the outer peripheral wall of the feed end 21 of the first screen cylinder 2, and by having the gear 6 mesh with the toothed grooves 23, the drive motor can drive the gear 6 to rotate, thereby driving the first screen cylinder 2 to rotate, thus facilitating the screening of the washed wet concrete.
[0060] In some embodiments, such as Figures 1 to 7 As shown, the inner wall of the housing 1 near the feed end 21 of the first screen cylinder 2 has an annular shell 7, which is inserted into the first screen cylinder 2. Several second spray pipes 71 are connected to the annular shell 7, which are inserted into the second screen cylinder 3, with the spray nozzles on the second spray pipes 71 facing the inner circumferential wall of the second screen cylinder 3. The opening 511 end of the second screen cylinder 3 is inserted into the annular shell 7 and rotates with it. The annular shell 7 has a water inlet pipe 72, and the other end of the water inlet pipe 72 is connected to the first spray pipe 4 through a quick connector.
[0061] It should be noted that by setting an annular shell 7 inside the housing 1 and installing a second spray pipe 71 on the annular shell 7, the material inside the second screen cylinder 3 can be washed, and the occurrence of fine sand clogging the second screen cylinder 3 can be reduced. By setting a water inlet pipe 72 on the annular shell 7 and connecting the water inlet pipe 72 to the first spray pipe 4 through a quick connector (not shown in the figure), a quick connection between the water inlet pipe 72 and the first spray pipe 4 can be achieved. A connecting plate is provided on the outside of the housing 1, and the connecting plate is bolted to the housing 1; the first spray pipe 4 is located between the connecting plate and the housing 1, and the first spray pipe 4 can be fixed to the housing 1 by the clamping action of the connecting plate and the outside of the housing 1.
[0062] In some embodiments, such as Figures 1 to 7 As shown, the annular shell 7 has an annular groove 73 on its outer peripheral wall, and a positioning bolt (not shown in the figure) is threaded onto the second screen cylinder 3. When the second screen cylinder 3 is inserted into the annular shell 7, the threaded end of the positioning bolt is located in the annular groove 73 to axially limit the second screen cylinder 3. The other end of the second screen cylinder 3 is connected to the first screen cylinder 2 through a connector to rotate synchronously with the first screen cylinder 2. A positioning ring 74 is also connected to the outer peripheral wall of the annular shell 7. The positioning ring 74 is used to contact the end of the second screen cylinder 3 to limit the insertion position of the second screen cylinder 3 and the annular shell 7.
[0063] It should be noted that the connecting parts on the second screen cylinder 3 are connected to the first screen cylinder 2 by bolts. After the threaded end of the positioning bolt on the second screen cylinder 3 is located in the annular groove 73, it can axially limit the second screen cylinder 3, which can improve the stability of the second screen cylinder 3 when it rotates.
[0064] In addition, since the second screen cylinder 3 is connected to the first screen cylinder 2 through a connector, the first screen cylinder 2 can also be axially limited by the cooperation of the positioning bolt and the annular groove 73.
[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
