Description

Technical Field

[0001] This utility model belongs to the technical field of brick making equipment, and in particular relates to a multi-station solid waste treatment wet molding machine. Background Technology

[0002] In municipal construction, road paving is often required. This involves not only paving bricks but also standard components such as curb stones. Traditional curb stones are strip-shaped objects made by cutting stone or casting natural sand and gravel concrete. They are used on the road surface to distinguish the boundaries between carriageways, sidewalks, green spaces, medians, and other parts of the road, playing a role in ensuring the safety of pedestrians and vehicles and ensuring the neatness of the road edges.

[0003] With the rapid pace of urban construction leading to the depletion of natural sand and gravel resources, and the excessive mining of stone materials causing environmental damage, existing manufacturers of concrete components such as curb stones are increasingly using recycled aggregates, industrial solid waste, and mining solid waste to produce curb stones. Curb stones made from these solid wastes can be sourced locally, absorb industrial waste, and have good environmental benefits. Currently, wet molding equipment is widely used in the production of concrete components such as curb stones. In actual production, the mixed materials are poured into a mold, then compacted to squeeze out the moisture, and finally demolded to remove the curb stone component from the mold for subsequent curing.

[0004] However, existing wet molding equipment generally uses long, strip-shaped production lines, arranging multiple processes sequentially, which results in a large footprint. In addition, the drainage performance of existing wet molding equipment is poor, making it difficult to effectively remove excess water from components such as curb stones made from wet slurry, which greatly affects the quality of the finished product. Furthermore, the cavity inside the curb stone mold in existing wet molding equipment is of a fixed size. When casting curb stones of different sizes, the cavity size cannot be changed, so the forming size of the curb stone inside the mold cannot be changed, resulting in poor flexibility and practicality, and thus certain limitations.

[0034] See further Figure 4 The aforementioned long core unit includes a right long side core structure 2-2-2 detachably connected to the mold outer frame assembly 2-1. A right upper sealing plate 2-2-8 and a right lower sealing plate 2-2-1, which are connected to the mold outer frame assembly 2-1, are detachably connected to the top and bottom of the right long side core structure 2-2-2, respectively. The detachable connection method is bolt connection. The long core unit also includes a right side plate 2-2-3 installed on the inner side of the right long side core structure 2-2-2.

[0035] The second long core unit includes a left long side core structure 2-2-6 detachably connected to the mold outer frame assembly 2-1.

The right side plate 2-2-3 and the left side plate 2-2-4 described above are both made of chromium-molybdenum steel.

[0037] Furthermore, the aforementioned adjustment unit 1 includes a rear side plate 2-2-11 detachably connected to the mold outer frame assembly 2-1, and an adjustment component 2-2-12 is installed on the inner side of the rear side plate 2-2-11; the adjustment component 2-2-12 includes an adjustment block 1 connected to the rear side plate 2-2-11, and a plate made of chromium molybdenum steel is fixed to the inner side of the adjustment block 1; a rear upper sealing plate 2-2-10 and a rear lower sealing plate 2-2-16 connected to the mold outer frame assembly 2-1 are detachably connected to the top and bottom of the adjustment component 2-2-12, respectively, and the aforementioned detachable connection method is bolt connection.

The detachable connection method is bolt connection. Both the front side plate 2-2-14 and the rear side plate 2-2-11 are made of chromium-molybdenum steel.

[0039] See further Figure 4 Several supporting protrusions 2-2-17 are provided on the inner edges of the lower right sealing plate 2-2-1, lower left sealing plate 2-2-5, lower front sealing plate 2-2-15, and lower rear sealing plate 2-2-16, protruding towards the center of the inner core assembly 2-2.

Several drainage holes are provided on the bottom plate of the inner cavity, and mating grooves are provided on the edges of the bottom plate to avoid the supporting protrusions 2-2-17. Through the cooperation of the mating grooves and the corresponding supporting protrusions 2-2-17, the bottom plate of the inner cavity is prevented from detaching from the lower mold device 2, allowing the bottom plate of the inner cavity and the inner cavity of the lower mold device 2 to form a space for accommodating materials. This structure allows the bottom plate of the inner cavity to move upwards relative to the lower mold device 2, facilitating the demolding of subsequent components and providing good performance. In actual operation, different inner cavity bottom plates can be replaced according to the specifications and dimensions of the curbstone for adaptation.

[0040] In actual operation, the size of the above-mentioned adjustment unit one and adjustment unit two can be adjusted according to the specifications and dimensions of the curbstone.

[0041] See further Figure 2 The aforementioned mold outer frame assembly 2-1 includes a lower outer frame 2-1-1 and an upper outer frame 2-1-2 that are connected by bolts. Both the lower outer frame 2-1-1 and the upper outer frame 2-1-2 have a number of corresponding positioning through holes, and each positioning through hole has a number of threaded holes around its periphery.

[0042] The upper left sealing plate 2-2-7, upper right sealing plate 2-2-8, upper front sealing plate 2-2-9, and upper rear sealing plate 2-2-10 are all detachably connected to the upper outer frame 2-1-2 by bolts.

[0043] like Figure 5 As shown, the aforementioned upper pressure head device 7 includes a pressure head main body structure 7-3 with a water outlet 7-5 on its side and connected to a lifting drive device. A pressure head cover plate 7-4 is fixedly connected to the top of the pressure head main body structure 7-3, and the pressure head cover plate 7-4 is connected to the lifting drive device. A press-drainage unit adapted to the molding cavity of the mold inner core assembly 2-2 is detachably connected to the bottom of the pressure head main body structure 7-3. See further details. Figure 6 A water outlet passage 7-7 is provided in the middle of the press-to-drain unit. Further, the water outlet passage 7-7 includes several manifold holes on the main plate of the press head, and radial grooves connected to each manifold hole. A drain connector 7-6 is connected to the manifold holes. Several drain suction ports 7-8 connected to the water outlet passage 7-7 are provided on the bottom surface of the press-to-drain unit. Several drain connectors 7-6 connected to the water outlet passage 7-7 are installed on the top surface of the press-to-drain unit. A manifold pipe is installed between the pipe connector installed on the water outlet 7-5 and the several drain connectors 7-6.

[0044] See further Figure 7 and Figure 8 The aforementioned press-to-drain unit includes a second press head main plate 7-2 fixedly connected to the bottom surface of the main press head structure 7-3. A first press head main plate 7-1, adapted to the molding cavity of the mold core assembly 2-2, is detachably connected to the second press head main plate 7-2. Water passage grooves 7-9 are formed on the mating surfaces of both the first press head main plate 7-1 and the second press head main plate 7-2, and the two sets of water passage grooves 7-9 connect to form a water outlet passage 7-7. A grooved pattern (in this invention, several circular grooves and several circular grooves) is provided on the bottom surface of the first press head main plate 7-1 to form anti-slip patterns on the curbstone.

[0045] A pipe is installed on the water outlet 7-5 via a connector, and a valve assembly is installed on the pipe. The valve assembly is connected to the vacuum water suction machine. A manifold and pipe are installed between the drain connector 7-6 and the connector installed on the water outlet 7-5.

[0046] A water guide plate is provided below the mounting plate device 1, located directly below the upper pressure head device 7 and mounted on the frame device 3. A water guide groove is provided on the top surface of the water guide plate.

[0047] During the compaction and molding process of the upper pressure head device 7, the aforementioned vacuum water suction machine controls the water outlet pipe to perform water suction. Under the action of the pressure head main board 7-1, the drainage connector 7-6 and the manifold installed on it discharge excess water through several drainage suction ports 7-8 and water outlet passages 7-7. After completing the above molding operation, the upper pressure head device 7 is lifted by the main hydraulic cylinder 6, so that the upper pressure head device 7 moves upward and resets to disengage from the lower mold device 2, which facilitates the molding machine to transfer the molding material in the corresponding lower mold device 2 out, thereby facilitating the subsequent ejection and demolding.

[0048] like Figure 1 As shown, the aforementioned lifting drive device includes a main hydraulic cylinder 6 mounted on the frame device 3 with its extended end facing downwards. A lifting guide device 5, slidably connected to the frame device 3 and capable of longitudinal movement, is mounted on the extended end of the main hydraulic cylinder 6. An upper pressure head device 7 is mounted on the lifting guide device 5. It also includes a hydraulic station (not shown) connected to the main hydraulic cylinder 6 and a supplementary oil tank 4. The main hydraulic cylinder 6 is a large-diameter hydraulic cylinder. In actual operation, the hydraulic station provides the power source for the longitudinal movement of the lifting guide device 5. The lifting guide device 5 is driven by the large-diameter main hydraulic cylinder 6, which can drive the lifting guide device 5 to achieve rapid lifting and lowering, ensuring output pressure and preventing the cylinder piston rod from twisting. Furthermore, the hydraulic station is connected to a valve station. The action of the main hydraulic cylinder 6 is controlled by a proportional valve, thereby achieving smooth start-up and rapid movement of the pressing action. The valves and pipes of the valve station use a large diameter to reduce the flow rate of the internal oil, thus extending the service life of the components. The replenishment oil tank 4 is located above the main hydraulic cylinder 6 and is connected to the large-diameter main hydraulic cylinder 6 via a filling valve to quickly replenish the main hydraulic cylinder 6 with oil. Additionally, several staggered oil baffles are installed inside the replenishment oil tank 4, with channels for liquid flow between each baffle and the inner wall of the tank 4. These baffles effectively buffer the flow rate of the liquid within the replenishment oil tank 4.

Guide column connecting blocks 5-3 are installed on the top of the two lifting guide columns 5-2 in each pair. Each of the aforementioned lifting guide columns 5-2 is slidably connected to the frame device 3.

[0050] In this embodiment, the aforementioned rotation drive device includes a gear ring mounted on the bottom of the mounting plate device 1, a drive motor mounted on the frame device 3, a reducer mounted on the output shaft of the drive motor, and a drive gear keyed to the output shaft of the reducer, the drive gear meshing with the gear ring. The aforementioned mounting plate device 1 is rotatably connected to the frame device 3 via a slewing bearing.

[0051] The aforementioned rotary drive configuration improves stable rotational speed and facilitates the rotation of the mounting plate device 1. Two drive gears can be provided, meshing at different positions on the outer circumference of the gear ring to ensure effective drive of the mounting plate device 1, enabling position switching between the three stations: material placement, compaction, and demolding. The slewing bearing facilitates rotational engagement between the frame device 3 and the mounting plate device 1, while also ensuring effective support for the mounting plate device 1 and improving its planar stability during rotation.

[0052] like Figure 11 As shown, the aforementioned mounting plate device 1 adopts a circular component, which can effectively reduce space occupation, make full use of the outer peripheral space of the mounting plate device 1, facilitate reasonable equipment layout, and facilitate operator monitoring of the equipment, thus improving operational convenience. The mounting plate device 1 includes a mounting turntable 1-2 rotatably connected to the frame device 3 via a slewing bearing. A turntable enclosure 1-1 is fixed to the outer peripheral wall of the mounting turntable 1-2, and an inner reinforcing sleeve 1-6 is coaxially fixed at the center. A multi-group partition plate 1-3 extending radially along the mounting turntable 1-2 and distributed at equal angles is fixed between the turntable enclosure 1-1 and the inner reinforcing sleeve 1-6, dividing the top surface of the mounting turntable 1-2 into several working areas. Several permeable holes are opened on the mounting turntable 1-2, distributed in each working area. Multiple mounting through holes 1-7 opened on the mounting plate device 1 are respectively opened on the mounting turntable 1-2 in multiple working areas. In this embodiment, three partition plates 1-3 are provided to divide the top surface of the mounting turntable 1-2 into three working areas, and three mounting through holes 1-7 are provided, thereby enabling three lower mold devices 2 to be provided.

[0053] Multiple sets of positioning pins 1-5 are provided around each mounting through hole 1-7 and are fixedly connected to the mounting turntable 1-2 for positioning the lower mold device 2. The positioning pins 1-5 pass through the positioning through holes opened on the corresponding lower outer frame 2-1-1 and upper outer frame 2-1-2. Several threaded holes are opened around each positioning through hole. A bolt cap 1-4 is installed on the top of each positioning pin 1-5. The bolt cap 1-4 is connected to the lower mold device 2 by bolts for fixing the lower mold device 2.

[0054] See further Figure 10 The aforementioned frame device 3 includes an upper frame seat 3-3 and a lower frame seat 3-1 distributed vertically. A plurality of longitudinally arranged fixing posts 3-2 are provided between the upper frame seat 3-3 and the lower frame seat 3-1 to connect the two as a whole. The upper and lower parts of the fixing posts 3-2 are provided with external threads and are connected to the corresponding upper frame seat 3-3 and lower frame seat 3-1 through lock nuts. In this embodiment, the aforementioned fixing posts 3-2 are provided in three and the three fixing posts 3-2 are distributed in a triangle. The inner reinforcing sleeve 1-6 in the mounting plate device 1 is rotatably connected to one fixing post 3-2 through a rolling bearing.

[0055] Working principle:

[0056] During the molding process, the three lower mold devices 2 are first rotated to the above-mentioned material feeding station, compaction station and demolding station under the drive of the rotation drive device. Then, the material is fed into the lower mold device 2 located at the material feeding station. The above-mentioned vibration device contacts the inner cavity bottom plate of the lower mold device 2 and applies vibration to compact the raw material. After the vibration is completed, the vibration device returns to its original position.

[0057] Then, the drive device is started, which moves the lower mold device 2, which has completed the fabric, to below the upper pressure head device 7. The main hydraulic cylinder 6 in the lifting drive device is started, which drives the upper pressure head device 7 to press down and compact the raw material in the lower mold device 2. During the compaction process, the upper pressure head device 7 can discharge excess water. After the above molding operation is completed, the upper pressure head device 7 is lifted by the main hydraulic cylinder 6, so that the upper pressure head device 7 moves up and resets to disengage from the lower mold device 2, so that the molding machine can transfer the molded material in the corresponding lower mold device 2 out, thereby facilitating the subsequent ejection and demolding.

[0058] Then, the drive device is started, which moves the lower mold device 2, which has completed the compaction and molding, to the demolding station and faces the demolding ejection device. The demolding ejection device pushes the molded curb stones and other components upward. After transferring the curb stones and other components to the next process, the demolding ejection device returns to its downward position.

[0059] Finally, the drive unit is started, which moves the lower mold device 2, which has completed the demolding operation, to the fabric placement station, directly facing the vibration device.
