Description

Technical Field

[0001] The invention relates to the technical field of cement pole production, and in particular to a sediment screening and washing device for cement pole production. Background Art

[0002] A utility pole is a pole for laying cables. It is used for the transformation of high and low voltage electricity, communications, urban and rural power grids, and the laying of communication cables. It is one of the important infrastructures for power supply and communications and is generally used for the laying of lines for the State Grid, mobile companies, and communications companies.

[0003] Cement poles are a type of electric poles made of cement, sand, and steel bars. Among them, the soil content of sand is one of the factors that affect the quality of cement poles. In the prior art, sand screening and washing devices are usually used to screen sand. The soil in the sand is mixed with water to form muddy water and discharged.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0044] In a specific embodiment of the present invention, Figures 1 to 9 As shown, it includes a support frame 100, on which a screening and washing assembly is installed, a feeding assembly connected to the screening and washing assembly is fixed at one end of the support frame 100, and is used to transport sand and gravel to be screened and washed into the screening and washing assembly, a guide assembly for guiding mud, water or sand and gravel is swingably connected below the screening and washing assembly, a mud and water treatment assembly is arranged below one end of the guide assembly, a water supply assembly is installed on the mud and water treatment assembly, one end of the water supply assembly is connected to the mud and water treatment assembly, and the other end of the water supply assembly is connected to the screening and washing assembly.

[0045] In a specific embodiment of the present invention, Figures 1 to 8 As shown, the sieve washing assembly includes an inner cylinder 200, an outer cylinder 300 and a power assembly. The inner cylinder 200 is coaxially rotatably arranged in the outer cylinder 300. The outer cylinder 300 is rotatably connected to the support frame 100. The power assembly is installed on the support frame 100, and the power assembly is transmission-connected to the outer cylinder 300. Specifically, both ends of the inner cylinder 200 are rotatably connected to the outer cylinder 300 through a first bearing; and both ends of the outer cylinder 300 are rotatably connected to the support frame 100 through a second bearing. Figure 5 and 6 As shown, a plurality of reinforcing ribs are fixed on the circumferential inner wall of the inner cylinder 200. The reinforcing ribs can increase the deformation resistance of the inner cylinder 200 and can turn over the sand and gravel that need to be screened, thereby increasing the screening efficiency.

[0046] A plurality of first through holes 210 for passage of mud and water are provided on the circumferential wall of the inner cylinder 200, a plurality of second through holes 310 for passage of sand and gravel are provided on the circumferential wall of the outer cylinder 300, and a plurality of third through holes 220 for passage of sand and gravel are provided on the circumferential wall of the inner cylinder 200; the aperture of the first through hole 210 is smaller than the aperture of the third through hole 220, the aperture of the third through hole 220 is larger than the maximum outer contour of sand and gravel, and the aperture of the second through hole 310 is larger than or equal to the aperture of the third through hole 220.

[0047] A control component is installed between the support frame 100, the inner tube 200 and the outer tube 300, and the control component can control the connection or stagger of the second through hole 310 with the first through hole 210 or the third through hole 220;

[0048] The principle is as follows: during screening and washing, the second through hole 310 is connected with the first through hole 210 and staggered with the third through hole 220, so muddy water falls on the guide plate 600 after passing through the first through hole 210, and then falls into the sedimentation box 1100; after screening and washing, the second through hole 310 is staggered with the first through hole 210 and connected with the third through hole 220, so sand and gravel fall on the guide plate 600 after passing through the third through hole 220 and the second through hole 310 in sequence, and then fall on the collection device. The collection device can be a vehicle, a box or a conveyor belt, etc.

[0049] In a specific embodiment of the present invention, Figures 1 to 5 As shown in FIGS. 7 to 9, the control assembly includes a first telescopic rod 110, a stopper block 400, a stopper rod 230 and a slot 320. The slot 320 is provided on the outer cylinder 300. One end of the stopper rod 230 is fixedly connected to the inner cylinder 200. The other end of the stopper rod 230 protrudes out of the slot 320. The slot 320 and the stopper rod 230 are slidably matched. The first telescopic rod 110 is fixedly connected to the support frame 100 through a fixed block. The fixed block is provided with a channel slidably connected to the stopper block 400. One end of the stopper block 400 is fixedly connected to the telescopic end of the first telescopic rod 110. The sliding track of the stopper block 400 intersects with the rotation track of the stopper rod 230. The first telescopic rod 110 can be a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0050] The principle is: Figure 7As shown, at this time, the outer cylinder 300 rotates clockwise, the limit rod 230 is located at one end of the slot 320, the second through hole 310 is connected to the first through hole 210 and is staggered with the third through hole 220, and when the outer cylinder 300 rotates, the limit rod 230 is driven to rotate through the slot 320, and the limit rod 230 drives the inner cylinder 200 to rotate. When the inner cylinder 200 rotates, the sand and stones that need to be screened are turned over, and the muddy water flows out from the first through hole 210 and falls on the guide plate 600; after the screening is completed, the outer cylinder 300 rotates counterclockwise. At this time, the outer cylinder 300 can drive the inner cylinder 200 to rotate through friction, but the rotation speed of the inner cylinder 200 is not necessarily equal to that of the outer cylinder 300. If the rotation speeds of the two are not equal, as the outer cylinder 300 rotates, the limit rod 230 will eventually be located at the other end of the slot 320 (i.e. Figure 8 As shown in the figure, at this time, the second through hole 310 is staggered with the first through hole 210 and connected with the third through hole 220, and the outer cylinder 300 continues to rotate, so that the sand and stones pass through the third through hole 220 and the second through hole 310 in sequence and fall on the guide plate 600; if the outer cylinder 300 rotates counterclockwise at the same speed as the inner cylinder 200, that is, the second through hole 310 cannot be staggered with the first through hole 210 and connected with the third through hole 220, the outer cylinder 300 stops rotating first, and the first telescopic rod 110 The telescopic end is extended, and the telescopic end drives the limit block 400 and the fixed block to slide relative to each other. The end of the limit block 400 away from the first telescopic rod 110 intersects with the rotation track of the limit rod 230. At this time, the reduction motor 800 is controlled by the external controller to rotate slowly, so that the outer cylinder 300 rotates slowly, and the inner cylinder 200 also rotates. When the limit rod 230 is connected to the limit block 400, the outer cylinder 300 continues to rotate until the limit rod 230 is located at the other end of the slot 320 (i.e. Figure 8 As shown), at this time, the second through hole 310 is staggered with the first through hole 210 and connected with the third through hole 220, and then the telescopic end of the first telescopic rod 110 contracts, so that the limit block 400 is away from the limit rod 230. At this time, the reduction motor 800 is started normally, and the outer cylinder 300 rotates counterclockwise, and the sand and stone pass through the third through hole 220 and the second through hole 310 in sequence and then fall on the guide plate 600; after the sand and stone are discharged, the end of the limit block 400 away from the first telescopic rod 110 intersects with the rotation trajectory of the limit rod 230, and the outer cylinder 300 rotates clockwise. When the limit rod 230 is connected to the limit block 400, the outer cylinder 300 continues to rotate until the limit rod 230 is located at one end of the slot 320 (i.e. Figure 7 The reset is completed and the next screening is ready.

[0051] In a specific embodiment of the present invention, Figures 1 to 5As shown in Figures 7 to 9, the power assembly includes a reduction motor 800, a driving wheel is fixed on the output shaft of the reduction motor 800, a driven wheel is fixed on the outer cylinder 300, and the driven wheel is connected to the driving wheel through a transmission component. Specifically, the driving wheel and the driven wheel can be pulleys, sprockets or synchronous pulleys, and the corresponding transmission components are belts, chains or synchronous belts.

[0052] In a specific embodiment of the present invention, Figures 1 to 6 As shown, the feeding assembly includes a first auger conveyor 500 fixedly connected to the support frame 100 , and the discharge end of the first auger conveyor 500 is gap-matched with one end of the inner cylinder 200 and penetrates into the inner cylinder 200 .

[0053] When in use, the sand and gravel to be screened are placed into the hopper of the first auger conveyor 500 , and the motor of the first auger conveyor 500 is started, so that the auger of the first auger conveyor 500 rotates, and the sand and gravel are transported into the inner tube 200 .

[0054] In a specific embodiment of the present invention, Figures 1 to 6 As shown, a striking assembly for striking the outer cylinder 300 is fixed on the support frame 100, and the striking assembly includes a rotating shaft 900, a striking hammer 1000, and a driven gear 910. The rotating shaft 900 is rotatably mounted on the top of the support frame 100, one end of the striking hammer 1000 is rotatably connected to the rotating shaft 900, and the other end of the striking hammer 1000 can be in contact with or separated from the outer cylinder 300, the driven gear 910 is fixedly connected to one end of the rotating shaft 900, and a gear ring 330 is fixed on the outer cylinder 300, and the gear ring 330 is meshed with the driven gear 910.

[0055] The principle is as follows: during screening and washing, the outer cylinder 300 drives the gear ring 330 to rotate, the gear ring 330 meshes with the driven gear 910, the driven gear 910 rotates, the driven gear 910 drives the rotating shaft 900 to rotate, the rotating shaft 900 drives the hammer 1000 to rotate, the hammer 1000 strikes the outer cylinder 300 to vibrate the outer cylinder 300, the inner wall of the outer cylinder 300 contacts the outer wall of the inner cylinder 200, then when the outer cylinder 300 vibrates, the inner cylinder 200 also vibrates, reducing the probability of the first through hole 210 being blocked.

[0056] In a specific embodiment of the present invention, Figures 1 to 5 As shown, the guide assembly includes a guide plate 600 and a second telescopic rod 700. The guide plate 600 is rotatably mounted on the support frame 100 and is located below the screening assembly. Upward extending baffles are fixed on both sides of the guide plate 600. The second telescopic rod 700 is rotatably connected to the support frame 100, and the telescopic end of the second telescopic rod 700 is rotatably connected to the bottom surface of one end of the guide plate 600.

[0057] The principle is: Figures 1 to 3As shown in FIGS. 4 and 5, during screening and washing, the telescopic end of the second telescopic rod 700 is in the extended state, and the end of the guide plate 600 close to the sedimentation tank 1100 is the lower end, so as to guide the muddy water falling on the guide plate 600, and the muddy water falls into the sedimentation tank 1100 under the action of gravity; when the screening and washing is completed, as Figure 4 shown, the telescopic end of the second telescopic rod 700 contracts, the guide plate 600 swings, and the end of the guide plate 600 away from the sedimentation tank 1100 is the lower end, so as to guide the sand and stones falling on the guide plate 600, and the sand and stones fall onto the collection device under the action of gravity. The collection device can be a vehicle, a box body or a conveyor belt, etc. The second telescopic rod 700 can be a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0058] In a specific embodiment of the present invention, as Figures 1 to 5 shown, the mud treatment assembly includes a sedimentation tank 1100 and a second auger conveyor 1200 for discharging sludge. The bottom end of the sedimentation tank 1100 is fixedly connected and communicated with the second auger conveyor 1200, and a discharge valve 1210 is arranged at the discharge end of the second auger conveyor 1200; the outer wall of the sedimentation tank 1100 is fixedly connected with the top end of a ladder 1300 for staff to put flocculant into the sedimentation tank 1100.

[0059] The principle is as follows: during or after one screening and washing process, the staff climbs up the ladder 1300 and puts flocculant (such as polyacrylamide) into the sedimentation tank 1100, so that the soil in the muddy water precipitates into sludge, and the sludge sinks to the bottom of the sedimentation tank 1100 and into the second auger conveyor 1200, so that the water in the upper half of the sedimentation tank 1100 is clean water containing no or very little soil components. The water pump 1600 and the filter 1500 are used to pump it out and preliminarily screen the next batch of sand and stones to reduce the consumption of clean water. When the sludge in the sedimentation tank 1100 reaches a certain amount (such as when it is close to the filter 1500), the second auger conveyor 1200 is started and the discharge valve 1210 is opened, then the sludge is discharged. A sludge transport vehicle can be arranged below the discharge valve 1210 to transport the sludge away. Since the sludge is located at the bottom layer and the water is located at the upper layer, the sludge is discharged before the water. After the sludge is discharged, there is still some water that has not been discharged. The staff can use this water to brush the inner wall of the sedimentation tank 1100 and the water inlet end of the filter 1500, and then open the discharge valve 1210 to discharge the sewage into the sludge transport vehicle.

[0060] In a specific embodiment of the present invention, as Figure 1 and 3As shown in FIGS. 0 to 5, the water supply assembly includes a water pump 1600, a connecting pipe 1400, and a filter 1500. The water pump 1600 is fixedly connected to the outer wall of the sedimentation tank 1100 through a mounting plate. The filter 1500 is fixed in the middle of the inner wall of the sedimentation tank 1100. The water inlet end of the water pump 1600 is fixedly connected to the sedimentation tank 1100. The filter 1500 is communicated with the water inlet end of the water pump 1600 through a through hole formed in the sedimentation tank 1100. One end of the connecting pipe 1400 is communicated with the water outlet end of the water pump 1600. The other end of the connecting pipe 1400 is rotatably inserted into a jack coaxially arranged at one end of the inner cylinder 200. The connecting pipe 1400 and the jack are sealed through a sealing ring. A plurality of spray holes 240 communicated with the jack are formed in the side wall of the inner cylinder 200. A bracket 120 is fixed on the support frame 100, and the bracket 120 is fixedly connected to the connecting pipe 1400.

[0061] The principle is as follows: Through the arrangement of the water pump 1600 and the filter 1500, the water in the sedimentation tank 1100 can be transported into the inner cylinder 200 to preliminarily screen and wash the sand and stones, realizing the recycling of water and facilitating the conservation of water resources.

[0062] In a specific embodiment of the present invention, as Figure 1 and 3 shown in FIGS. 0 to 5, it further includes a clear water pipe 1610. One end of the clear water pipe 1610 is fixedly connected and communicated with the connecting pipe 1400, and the other end of the clear water pipe 1610 is connected with a switch valve 1611.

[0063] The principle is as follows: The switch valve 1611 can be communicated with a municipal water supply pipe. Clear water is supplied into the switch valve 1611 through the water supply pipe, and then the clear water enters the jack through the clear water pipe 1610 and the connecting pipe 1400 to wash the sand and stones again. Since the water in the sedimentation tank 1100 can preliminarily screen and wash the sand and stones, the demand for clear water can be reduced.

[0064] The working principle of a sand and sediment screening and washing device for the production of cement poles according to the present invention:

[0065] Put the sand and stones to be screened and washed into the hopper of the first auger conveyor 500, start the motor of the first auger conveyor 500, so that the auger of the first auger conveyor 500 rotates, and then transport the sand and stones into the inner cylinder 200.

[0066] Start the reduction motor 800, and drive the outer cylinder 300 to rotate clockwise through the driving wheel, driven wheel and transmission components. At this time, the limiting rod 230 is located at one end of the slot 320, the second through hole 310 communicates with the first through hole 210 and is staggered from the third through hole 220. The outer cylinder 300 drives the limiting rod 230 to rotate through the slot 320, and the limiting rod 230 drives the inner cylinder 200 to rotate. The reinforcing rib plates in the inner cylinder 200 and the inner wall of the inner cylinder 200 turn the sand and stones. At this time, the water supply assembly is started, and the water pump 1600 transports the water in the sedimentation tank 1100 into the jack of the inner cylinder 200 through the filter 1500, and sprays out from the water spraying holes 240 to perform preliminary screening and washing on the sand and stones, realizing the recycling of water, which is beneficial to saving water resources. The muddy water falls on the guide plate 600 through the first through hole 210. At this time, the telescopic end of the second telescopic rod 700 is in the extended state, and one end of the guide plate 600 close to the sedimentation tank 1100 is lower, and the muddy water falls into the sedimentation tank 1100 under the action of gravity. When the outer cylinder 300 rotates, it drives the gear ring 330 to rotate, and the gear ring 330 drives the driven gear 910, the rotating shaft 900 and the knocking hammer 1000 to rotate. The knocking hammer 1000 knocks on the outer cylinder 300, causing the outer cylinder 300 and the inner cylinder 200 to vibrate, reducing the probability of blockage of the first through hole 210.

[0067] The preliminary cleaning can last from several minutes to more than ten minutes, and then the water pump 1600 is turned off. The switching valve 1611 can be connected to the municipal water supply pipe, and clean water is supplied into the switching valve 1611 through the water supply pipe. Then the clean water enters the jack through the clean water pipe 1610 and the connecting pipe 1400, and the water sprays out from the water spraying holes 240 to wash the sand and stones again. Since the water in the sedimentation tank 1100 can perform preliminary screening and washing on the sand and stones, the demand for clean water can be reduced, which is beneficial to saving water resources.

[0068] During or after a screening process, the staff climbs up the climbing ladder 1300 and puts a flocculant (such as polyacrylamide) into the sedimentation tank 1100, so that the soil in the muddy water precipitates into sludge. The sludge sinks to the bottom of the sedimentation tank 1100 and the second auger conveyor 1200, so that the water in the upper half of the sedimentation tank 1100 is clean water containing no or very little soil components. Use the water pump 1600 and the filter 1500 to pump it out and perform preliminary screening and washing on the next batch of sand and stones to reduce the usage of clean water.

[0069] When the sludge in the sedimentation tank 1100 reaches a certain amount (such as when it is close to the filter 1500), the second auger conveyor 1200 is started and the discharge valve 1210 is opened, and the sludge is discharged. A sludge transport vehicle can be set under the discharge valve 1210 to transport the sludge. Since the sludge is located at the bottom layer and the water is located at the upper layer, the sludge is discharged before the water. After the sludge is discharged, some water is not discharged. The staff can use this water to brush the inner wall of the sedimentation tank 1100 and the water inlet end of the filter 1500, and then open the discharge valve 1210 to discharge the sewage into the sludge transport vehicle.

[0070] After the screening and washing is completed, the telescopic end of the second telescopic rod 700 is retracted, and the guide plate 600 swings, and the end of the guide plate 600 away from the sedimentation box 1100 is the lower end. The outer cylinder 300 rotates counterclockwise, and at this time, the outer cylinder 300 can drive the inner cylinder 200 to rotate through friction, but the rotation speed of the inner cylinder 200 is not necessarily equal to that of the outer cylinder 300. If the rotation speeds of the two are not equal, as the outer cylinder 300 rotates, the limit rod 230 will eventually be located at the other end of the slot 320 (i.e. Figure 8 As shown in the figure, at this time, the second through hole 310 is staggered with the first through hole 210 and connected with the third through hole 220, and the outer cylinder 300 continues to rotate, so that the sand and stones pass through the third through hole 220 and the second through hole 310 in sequence and fall on the guide plate 600; if the outer cylinder 300 rotates counterclockwise at the same speed as the inner cylinder 200, that is, the second through hole 310 cannot be staggered with the first through hole 210 and connected with the third through hole 220, the outer cylinder 300 stops rotating first, and the first telescopic rod 110 The telescopic end is extended, and the telescopic end drives the limit block 400 and the fixed block to slide relative to each other. The end of the limit block 400 away from the first telescopic rod 110 intersects with the rotation track of the limit rod 230. At this time, the reduction motor 800 is controlled by the external controller to rotate slowly, so that the outer cylinder 300 rotates slowly, and the inner cylinder 200 also rotates. When the limit rod 230 is connected to the limit block 400, the outer cylinder 300 continues to rotate until the limit rod 230 is located at the other end of the slot 320 (i.e. Figure 8 As shown), at this time, the second through hole 310 is staggered with the first through hole 210 and connected to the third through hole 220, and then the telescopic end of the first telescopic rod 110 contracts, so that the limit block 400 is away from the limit rod 230. At this time, the reduction motor 800 is started normally, and the outer cylinder 300 rotates counterclockwise, and the sand and stone fall on the guide plate 600 after passing through the third through hole 220 and the second through hole 310 in turn, and the sand and stone fall on the collection device under the action of gravity; after the sand and stone are discharged, the end of the limit block 400 away from the first telescopic rod 110 intersects with the rotation trajectory of the limit rod 230, and the outer cylinder 300 rotates clockwise. When the limit rod 230 is connected to the limit block 400, the outer cylinder 300 continues to rotate until the limit rod 230 is located at one end of the slot 320 (i.e. Figure 7 The reset is completed and the next screening is ready.
