Description

Technical Field

[0001] The invention relates to the technical field of cement-stabilized gravel, in particular to a vibration stirring device for cement-stabilized gravel. Background Art

[0002] Cement-stabilized gravel is a basic material widely used in road engineering. It is made by mixing cement, gravel and water, and has the characteristics of high strength and stability. The vibrating mixer applies high-frequency vibration during the mixing process to make the mixture particles fully move and tightly combined, improving the mixing quality and efficiency, and enhancing the sufficiency of the cement hydration reaction, thereby improving the overall performance of the mixture.

[0003] During the production of cement-stabilized gravel, after the mixer completes its mixing operation, the cement and gravel in the cement-stabilized gravel mixture tend to adhere to the surface of the mixing structure. Current cleaning methods rely primarily on manual cleaning with tools after each mixing operation is completed, or simple water flushing. However, these existing technologies present numerous inconveniences. On the one hand, manual cleaning is labor-intensive and inefficient, and incomplete cleaning easily leaves dead corners. Residues can affect the quality of the mixture during the next mixing operation. On the other hand, water flushing is ineffective for hardened or difficult-to-wash residues, and cannot effectively remove stubborn attachments, resulting in incomplete equipment cleaning.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0020] The present invention provides two technical solutions: Figures 1-10 The first embodiment is shown: a vibration mixing device for cement-stabilized gravel, including a mixing unit 1, including a support component 11, a mixing tank 12 fixedly connected to the inside of the support component 11, and a mixing component 13 fixedly connected to the outside of the mixing tank 12.

[0021] In this embodiment, the self-cleaning unit 2 includes a spray assembly 21 fixedly connected to the inner wall of the stirring tank 12 , and a driving assembly 22 rotatably connected to the outer side of the stirring assembly 13 .

[0022] In this embodiment, the stirring assembly 13 includes a fixing base 131 fixedly connected to the outside of the stirring tank 12 , a lifting member 132 fixedly connected to the top of the fixing base 131 , and a vibrating stirring member 133 rotatably connected to the bottom of the lifting member 132 .

[0023] In this embodiment, the spray assembly 21 includes a softening component 211 fixedly connected to the inner wall of the stirring tank 12 , and a flushing component 212 fixedly connected to the inner wall of the stirring tank 12 and located below the softening component 211 .

[0024] Figures 1-10 A second embodiment is shown, which mainly differs from the first embodiment in that it includes a stirring unit 1, including a support component 11, a stirring tank 12 fixedly connected to the inside of the support component 11, and a stirring component 13 fixedly connected to the outside of the stirring tank 12.

[0025] In this embodiment, the self-cleaning unit 2 includes a spray assembly 21 fixedly connected to the inner wall of the stirring tank 12 , and a driving assembly 22 rotatably connected to the outer side of the stirring assembly 13 .

[0026] In this embodiment, the stirring assembly 13 includes a fixing base 131 fixedly connected to the outside of the stirring tank 12 , a lifting member 132 fixedly connected to the top of the fixing base 131 , and a vibrating stirring member 133 rotatably connected to the bottom of the lifting member 132 .

[0027] In this embodiment, the spray assembly 21 includes a softening component 211 fixedly connected to the inner wall of the stirring tank 12 , and a flushing component 212 fixedly connected to the inner wall of the stirring tank 12 and located below the softening component 211 .

[0028] In this embodiment, the support assembly 11 includes a base 111, four groups of support columns 112 vertically fixedly connected to the top of the base 111, and a fixing ring 113 fixedly connected to the top of the four groups of support columns 112, and the mixing tank 12 is fixedly connected to the inside of the fixing ring 113.

[0029] In this embodiment, the bottom of the mixing tank 12 is connected to a discharge pipe 121, and a valve is fixedly connected to the outside of the discharge pipe 121. It should be noted that the valve is not shown in the accompanying drawings of the present invention, and the valve is a commonly used existing technology for the discharge pipe 121 of the mixing tank 12.

[0030] Specifically, when the equipment is running, cement, gravel and water are put into the mixing tank 12 in proportion, and the mixing motor 1334 is started, driving the rotating shaft 1331 and the stirring blade 1333 on the vibration frame 1332 to rotate at a low speed to stir the mixture. At the same time, an ultrasonic transducer is installed inside the vibration frame 1332 to convert the high-frequency electrical oscillation signal generated by the ultrasonic generator into mechanical vibration and transmit it to the vibration frame 1332. When the ultrasonic vibration generated by the ultrasonic transducer propagates inside the vibration frame 1332, the vibration frame 1332 and the stirring blade 1333 produce High-frequency vibration is generated. The frequency of ultrasonic vibration is usually much higher than the rotation frequency of the vibration frame 1332. The two are independent of each other and will not interfere with each other. Ultrasonic vibration can make the cement-stabilized gravel mixture more fully mixed and dispersed on a microscopic scale. After the mixing is completed, the operator manually controls to open the valve on the discharge pipe 121, so that the discharge pipe 121 at the bottom of the mixing tank 12 is connected. The evenly mixed cement-stabilized gravel mixture is discharged through the discharge pipe 121 into a transport container pre-placed below the discharge pipe 121 for use in subsequent road construction processes.

[0031] In this embodiment, the lifting member 132 includes an adjusting frame 1321 fixedly connected to the top of the fixing seat 131, and a partition 1322 is fixedly connected to the internal horizontal position of the adjusting frame 1321. A screw rod 1323 is rotatably connected between the side where the partition 1322 and the adjusting frame 1321 are close to each other. The bottom of the partition 1322 is fixedly connected to a driving motor 1324, and a through hole is opened on the top of the partition 1322. The output end of the driving motor 1324 is fixedly connected to the bottom end of the screw rod 1323 through the through hole. The outer side of the screw rod 1323 is threadedly connected to a lifting block 1325, and the top of the lifting block 1325 is fixedly connected to a support frame 1326.

[0032] In this embodiment, an opening is defined at the top of the adjustment frame 1321 for the support frame 1326 to slide.

[0033] Specifically, the support frame 1326 can move up and down through the opening, and the opening also forms a limit between the support frame 1326, limiting the support frame 1326 and the lifting block 1325 to rotate synchronously with the screw rod 1323.

[0034] In this embodiment, referring to Figure 2 As shown, the vibrating stirring member 133 includes a rotating shaft 1331 fixedly connected to the bottom of the support frame 1326, the bottom end of the rotating shaft 1331 is fixedly connected to the vibration frame 1332, and the outer side of the vibration frame 1332 is cross-fixedly connected with a plurality of stirring blades 1333. After the stirring motor 1334 is started, the output end of the motor drives the rotating shaft 1331 and the vibration frame 1332 fixedly connected to the rotating shaft 1331 and the stirring blades 1333 to rotate at a low speed in the stirring tank 12 to stir the mixture.

[0035] Specifically, an ultrasonic transducer is installed inside the vibration frame 1332 to convert the high-frequency electrical oscillation signal generated by the ultrasonic generator into mechanical vibration and transmit it to the vibration frame 1332. When the ultrasonic vibration generated by the ultrasonic transducer propagates inside the vibration frame 1332, the vibration frame 1332 and the stirring plate 1333 generate high-frequency vibration.

[0036] In this embodiment, referring to Figure 1-Figure 2 As shown, a stirring motor 1334 is fixedly connected to the top of the support frame 1326 , and a rotating hole is opened on one side of the support frame 1326 close to the stirring motor 1334 , and the output end of the stirring motor 1334 passes through the rotating hole and is fixedly connected to the top of the rotating shaft 1331 .

[0037] In this embodiment, the softening member 211 includes a first water pipe 2111 fixedly connected to the inner wall of the mixing tank 12, the outer side of the first water pipe 2111 is connected to a plurality of groups of atomizing nozzles 2112, and the outer side of the first water pipe 2111 is connected to a first water inlet pipe 2113. Figure 1-Figure 2 As shown, the first water pipe 2111 is placed at the edge of the mixing tank 12, that is, the top of the mixing tank 12. When the cement-stabilized gravel is processed in the mixing tank 12, the material filling rate is generally between 50% and 70% to ensure that the material can be evenly stirred and mixed. Therefore, the first water pipe 2111 is located at the top of the mixing tank 12 and will not directly contact with cement and other materials.

[0038] In this embodiment, referring to Figure 6 As shown, a first water tank 2114 is fixedly connected to the top of the base 111, and a first water pump 2115 is connected to the top of the first water tank 2114 through a water pipe. The water outlet of the first water pump 2115 is connected to a first delivery pipe 2116, and the end of the first delivery pipe 2116 away from the first water pump 2115 is connected to the first water inlet pipe 2113, and the interior of the first water tank 2114 is filled with a softener.

[0039] Specifically, the softener can be a cement dissolving agent or a corresponding aqueous agent that can soften cement. During the cleaning process, the softening part 211 is located higher than the flushing part 212, so it will be closed before the flushing part 212. That is to say, the flushing part 212 will continue to spray for a period of time to flush out the residue and residual softener.

[0040] In this embodiment, the flushing component 212 includes a second water pipe 2121 fixedly connected to the inner wall of the mixing tank 12 and located at the lower side of the first water pipe 2111. The outer side of the second water pipe 2121 is connected to a second water inlet pipe 2125, and the side of the second water pipe 2121 away from the mixing tank 12 is connected to several groups of nozzle components 213.

[0041] In this embodiment, a second water tank 2122 is fixedly connected to the top of the base 111, the top of the second water tank 2122 is connected to a second water pump 2123, the water outlet end of the second water pump 2123 is connected to a second delivery pipe 2124, the end of the second delivery pipe 2124 away from the second water pump 2123 is connected to the second water inlet pipe 2125, and the interior of the first water tank 2114 is filled with clean water.

[0042] Specifically, refer to Figure 1 and Figure 6 As shown, the second water pump 2123 pumps out the clean water in the second water tank 2122 and transports it to the second water pipe 2121 through the second delivery pipe 2124. The clean water is sprayed out from the high-pressure nozzle 2138 of the nozzle member 213 to form a strong high-pressure water flow. At this time, when the vibration stirring member 133 after shutdown is driven to rise and fall through this place by the lifting member 132, the high-pressure water flow washes off the residue adhering to the surface to achieve cleaning. The second delivery pipe 2124 is used to guide the water flow drawn out from the second water tank 2122 by the second water pump 2123 upward to the valve Inside the shell 223, the second water inlet pipe 2125 is used to connect the valve shell 223 and the second water pipe 2121 to guide the water flow into the second water pipe 2121. The valve shell 223 is a box with a hollow interior and its two ends are respectively connected to the second water inlet pipe 2125 and the second delivery pipe 2124, which is used to relay the water flow. At the same time, the valve shell 223 cooperates with the valve flap 225 that can rotate along the valve stem 224 to form a valve structure that cuts off the flow, controls the water flow entering the second water pipe 2121, and plays the role of releasing water during cleaning and stopping water during stirring.

[0043] In this embodiment, the nozzle component 213 includes a diverter pipe 2131 connected to the outside of the second water pipe 2121, the inside of the diverter pipe 2131 is fixedly connected to a limiting ring 2132, a connecting ring 2133 is placed on the top of the limiting ring 2132, the inside of the connecting ring 2133 is rotatably connected to a rotating pipe 2134, the outside of the rotating pipe 2134 is fixedly connected to an impeller 2135, a spiral groove 2136 is provided on the side of the diverter pipe 2131 close to the impeller 2135, and a return water port 2137 connected to the spiral groove 2136 is provided on the side of the rotating pipe 2134 close to the diverter pipe 2131, and the outside of the rotating pipe 2134 is connected to two groups of high-pressure nozzles 2138.

[0044] Specifically, after the water flows into the diversion pipe 2131, most of the water flows directly into the high-pressure nozzle 2138 along the rotating pipe 2134, while a part of the water flows spirally down along the spiral groove 2136 and enters the space where the impeller 2135 is located. Since the positions of the impeller 2135 and the spiral groove 2136 correspond, this spiral downward water flow impacts the impeller 2135, driving the impeller 2135 to rotate. When the impeller 2135 rotates, it drives the rotating pipe 2134 fixed to it to rotate together, and then drives the two groups of high-pressure nozzles 2138 connected to the outside of the rotating pipe 2134 to rotate. At the same time, the water flow entering from the spiral groove 2136 is driven by the impeller 2135, flows into the interior of the rotating pipe 2134 through the return water port 2137, and is finally ejected from the high-pressure nozzle 2138, forming a high-pressure water flow, which rinses the stirring components from multiple angles to achieve a thorough cleaning effect.

[0045] It should be noted that the rotation enables the high-pressure nozzle 2138 to spray water over a wider area, without the need to frequently move or adjust the nozzle position, so that the surface of the stirring component can be fully covered, thereby improving the cleaning effect. During the rotation process, the high-pressure water flow impacts the stirring component from different angles, so that the impact force of the water flow is more evenly distributed over the entire surface, thereby enhancing the impact effect on stubborn residues and more effectively removing firmly adhered cement and gravel.

[0046] In this embodiment, referring to Figure 8 As shown, the cross-sectional shape of the rotating tube 2134 is set to be T-shaped.

[0047] In this embodiment, referring to Figure 2 and Figure 4 As shown, the drive assembly 22 includes an extension rod 221 fixedly connected to the outside of the support frame 1326, and the bottom of the extension rod 221 is fixedly connected to the rack 222, and the outsides of the first delivery pipe 2116 and the second delivery pipe 2124 are fixedly connected to the valve housing 223, and the interiors of the two sets of valve housings 223 are rotatably connected to the valve stem 224, and the outsides of the two sets of valve stems 224 are fixedly connected to the valve flap 225, and the left ends of the two sets of valve stems 224 pass through and extend to the outsides of the two sets of valve housings 223 and are fixedly connected to the control gear 226.

[0048] In this embodiment, both sets of control gears 226 are engaged with the rack 222 .

[0049] Specifically, when the vibrating stirring member 133 moves upward, the rack 222 at the bottom of the extension rod 221 on its outside moves accordingly. When the rack 222 moves to the position of the valve housing 223, it engages with the control gear 226 and drives the control gear 226 to rotate. The control gear 226 drives the valve stem 224 to rotate, so that the valve flap 225 is flattened to achieve opening.

[0050] It should be noted that the length of the rack 222 is set to half the circumference of the control gear 226. Therefore, when the rack 222 is engaged with the control gear 226 and driven to rotate, it will only drive the valve flap 225 to realize a 90-degree opening and closing rotation.

[0051] In this embodiment, the cross-sectional shape of the support frame 1326 is set to be L-shaped, and the shapes of the first delivery tube 2116 and the second delivery tube 2124 are both set to be circular.

[0052] At the same time, the contents not described in detail in this specification belong to the existing technology well known to those skilled in the art.

[0053] Working principle: After the cement stabilized gravel is mixed, the valve of the discharge pipe 121 at the bottom of the mixing tank 12 is opened, and the uniformly mixed cement stabilized gravel mixture is discharged through the discharge pipe 121. After the discharge is completed, the valve of the discharge pipe 121 is closed, and the driving motor 1324 of the lifting member 132 is started, driving the screw rod 1323 to rotate, so that the lifting block 1325 rises along the screw rod 1323, and drives the entire vibrating stirring member 133 to move upward smoothly through the support frame 1326 until it is completely moved out of the mixing tank 12. When the vibrating stirring member 133 moves upward, the rack 222 at the bottom of the extension rod 221 outside it moves accordingly. When the rack 222 moves to the valve housing 223 position, it meshes with the control gear 226 and drives the control gear 226 to rotate. The control gear 226 drives the valve stem 224 to rotate, so that the valve disc 225 is opened, and the first delivery pipe 2116 and the second delivery pipe 2124 are connected to the softening member 211 and the flushing member 212 respectively, preparing for subsequent softening and flushing operations; As the vibrating stirring member 133 continues to move upward, the second water pump 2123 pumps out the clean water in the second water tank 2122 and delivers it to the second water pipe 2121 through the second delivery pipe 2124. The clean water is sprayed out from the high-pressure nozzle 2138 of the nozzle member 213 to form a strong high-pressure water flow. At this time, the vibrating stirring member 133 passes through this place, and the high-pressure water flow washes off the residue that is not firmly adhered to the surface, achieving pre-cleaning and removing most of the loose gravel and cement mixture residues; the vibrating stirring member 133 moves further upward and enters the softening member In area 211, the first water pump 2115 draws softener from the first water tank 2114 and delivers it to the first water pipe 2111 through the first delivery pipe 2116. The softener is sprayed out through the atomizing nozzle 2112 to form fine droplets that evenly adhere to the residual cement-stabilized gravel on the surface of the stirring component. According to the reaction characteristics of the softener, it stays for a period of time to allow the softener to fully penetrate and chemically react with the cement components in the residue, so that the hard cement lumps gradually soften and expand, loosening their adhesion to the surface of the stirring component.

[0054] After the softening treatment, the lifting member 132 drives the vibrating stirring member 133 to move downward and return to the stirring tank 12. During the downward movement, when the stirring member passes through the flushing member 212, the high-pressure water flow impacts the surface of the stirring member again, and the softened residue is completely washed off, completing the deep cleaning, restoring the stirring member to its original state, and preparing for the next round of stirring operation. At the same time, as the vibrating stirring member 133 moves downward, the rack 222 on its outer side contacts the control gear 226 again, and drives the gear to rotate in the opposite direction. The control gear 226 drives the valve stem 224 to rotate, so that the valve flap 225 is closed, thereby cutting off the water supply to the softening member 211 and the flushing member 212, and realizing the stop of the cleaning component; During the flushing process, the washed-off residue flows along the inner wall of the mixing tank 12 to the down pipe 121 with the water flow. Since the valve of the down pipe 121 remains closed during cleaning, the residue temporarily accumulates near the entrance of the down pipe 121. After completing the entire cleaning process, the valve of the down pipe 121 is opened, and the accumulated residue is discharged from the mixing tank 12 through the down pipe 121 along with the water flow, and enters the subsequent waste collection system or is directly discharged to a designated location, thereby realizing automatic cleaning of the residue, avoiding manual intervention, keeping the interior of the equipment clean, and preventing residue accumulation from affecting subsequent mixing operations and equipment performance.
