Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of engineering slag treatment, in particular to a screening and washing device for engineering slag and a use method thereof. BACKGROUND

[0002] During engineering operation, a large amount of slag is generally produced. In the process of treatment, in accordance with the principle of resource recycling and reuse, the slag is generally subjected to screening and washing. The screening and washing of the slag is to screen the slag into different sizes of soil blocks according to certain standards, and then to wash the screened soil blocks to wash the attachments on the surface of the soil blocks.

[0003] When the existing engineering slag screening and washing device processes the slag, the slag is conveyed through a vibrating screen and other devices by a conveying belt and other components to screen the slag, and to preliminarily separate large stones, soil blocks and small sand, soil and other materials. Since the surface of the large stones and soil blocks is still attached with sand, in order to facilitate the full recycling of the sand or the cleaning of the attachments on the surface of the large stones and soil blocks, and to improve the purity of the recycled materials and the reuse value, the screened large stones or soil blocks are washed by a high-pressure water gun or a spraying system. The screened large stones or soil blocks are conveyed through the spraying and washing position by the conveying belt to complete the washing, and finally the materials with different particle sizes are separated, and the purity and reuse value of the recycled materials are improved.

[0004] The existing engineering slag screening and washing device has the following deficiencies: Although the existing slag screening and washing device can screen and wash the slag produced in the engineering operation, the components of the existing slag washing part, such as the washing nozzle, are generally fixed in position. The conveying components convey the screened slag through the position where the fixed-position washing nozzle is located to achieve washing. However, since the shapes and sizes of the slag blocks are irregular, the washing angle of the fixed-position washing nozzle is limited when washing the slag blocks, and many positions of the slag blocks cannot be effectively washed, especially the downward position of the slag blocks. Moreover, during the conveying of the slag blocks through the washing position, if the slag blocks are blocked, the slag blocks will be accumulated, and the subsequent slag blocks cannot pass through normally, so that the washing cannot be effectively completed.

Each rotating disc 10 is uniformly provided with anti-skid protrusions. When the slag slides down the inclined guide plate 8, it will contact the rotating discs 10 at different positions. The rotation of the rotating discs 10 can cause the slag to be stirred and rolled during the sliding process, facilitating the flushing of the slag and stone blocks by the linkage flushing mechanism.

[0046] It should be noted that in order to avoid the slag stone passing through the inclined guide plate 8 too fast, the inclined angle of the inclined guide plate 8 can be set a little smaller, that is, a smaller suitable inclined angle is selected, and at the same time the length of the inclined guide plate 8 can be extended to ensure that the time of the slag passing through the inclined guide plate 8 is long enough.

[0047] In some specific embodiments, the support base 1 is provided with a sediment tank 16 on one side, and each group of the screening tank 2 is communicated with the transition chamber 33 and the sediment tank 16. The side of the sediment tank 16 can be provided with openings at different heights. The bottom side of the sediment tank 16 is provided with an openable tank door which is normally sealed. The sediment tank 16 is used to receive the discharged sludge water, facilitate the sludge water to be stratified, and accelerate the stratification by adding flocculating agent and other materials. Then the waste water is pumped out, leaving the sludge, and finally the sludge is dried. A heating element can also be installed at the bottom of the sediment tank 16 to facilitate the drying of the wet sludge.

[0048] In order to facilitate the pumping out of the stratified water, a water pump 35 can be installed outside the sediment tank 16. The water pump 35 is connected with a water pumping hose 36 which can extend into the sediment tank 16.

[0049] In some specific embodiments, as shown in FIG. 8, Figures 4 to 6The linkage flushing mechanism includes a fixed mounting plate 19, a movable mounting plate 17 and a push-up water spraying part. The fixed mounting plate 19 is fixedly connected above the screening box 2 and is parallel to the corresponding inclined guide plate 8. The movable mounting plate 17 is arranged above the fixed mounting plate 19. The push-up water spraying part is provided with multiple groups and is arranged on the movable mounting plate 17. The movable mounting plate 17 is fixedly connected with guide rods 23 on both sides. The guide rods 23 are perpendicular to the movable mounting plate 17. The screening box 2 is fixedly connected with guide sleeves 24 on both sides. The guide rods 23 correspondingly slide through the guide sleeves 24. The guide rods 23 are connected with the first springs 25 between the guide rods 23 and the guide sleeves 24. The guide rods 23 are fixedly connected with the baffle 22 at one end away from the movable mounting plate 17. The driving transmission mechanism includes a driving gear 26, a transmission gear 27, a linkage gear 20 and a cam 21. The cam 21 is rotatably connected to the outer wall of the screening box 2 through a rotating shaft and is matched with the baffle 22. The linkage gear 20 is coaxially connected with the cam 21. The driving gear 26 is coaxially connected with one of the synchronous wheels 13. The transmission gear 27 is rotatably connected to the outside of the screening box 2 through a rotating shaft and is meshed between the driving gear 26 and the linkage gear 20. The specification of the transmission gear 27 is between the specifications of the driving gear 26 and the linkage gear 20. The specification of the driving gear 26 is greater than the specification of the linkage gear 20. When the synchronous wheel 13 moves, it drives the driving gear 26 to rotate. The driving gear 26 drives the linkage gear 20 to rotate through the transmission gear 27, so that the cam 21 rotates. The cam 21 constantly pushes up the baffle 22 in the rotating process. The baffle 22 drives the movable mounting plate 17 to move towards the inclined guide plate 8 through the guide rod 23. In this process, the first spring 25 is stretched to generate a rebound force. When the cam 21 is separated from the baffle 22, the guide rod 23 drives the movable mounting plate 17 to reset under the action of the rebound force of the first spring 25, so as to realize the reciprocating movement of the movable mounting plate 17.

[0050] Wherein, each group of pushing and water spraying elements comprises an outer sleeve 18, an inner sliding tube 29 and a squeezing top element, the outer sleeve 18 penetrates through the movable mounting plate 17 and the fixed mounting plate 19 in sequence, and the outer sleeve 18 is slidable relative to the movable mounting plate 17 and the fixed mounting plate 19, a stretchable second spring 37 is connected between the top of the outer sleeve 18 and the movable mounting plate 17, the inner sliding tube 29 is slidingly inserted into the bottom of the outer sleeve 18, the inner sliding tube 29 and the outer sleeve 18 are communicated, a compressible third spring 32 is connected between the inner sliding tube 29 and the outer sleeve 18, the specification of the second spring 37 is larger than that of the third spring 32, under the same force condition, the third spring 32 deforms first than the second spring 37, the bottom of the inner sliding tube 29 is fixedly provided with a spherical nozzle 28, a plurality of spray holes are uniformly distributed on the spherical nozzle 28, and the spray holes are directed to different angle positions, one side of the screening box 2 is fixedly connected with a water tank 15 and a water delivery pump 5, the water inlet end of the water delivery pump 5 is communicated with the water tank 15, a thickened pipeline is additionally arranged at the water outlet end of the water delivery pump 5, and a plurality of flexible hoses are distributed on the thickened pipeline, the water outlet end of the water delivery pump 5 is communicated with the top of each outer sleeve 18 through the thickened pipeline and the matched flexible hoses, the squeezing top element comprises a first linkage rod 30 and a second linkage rod 31, one end of the first linkage rod 30 is movably connected with the bottom of the inner sliding tube 29 through a hinge, the other end is movably connected with one end of the second linkage rod 31 through a hinge, and the end of the second linkage rod 31 away from the first linkage rod 30 is movably connected with the outer sleeve 18 through a hinge. Figure 5 As shown, it is accommodated between the outer sleeve 18 and the inner sliding tube 29, when the movable mounting plate 17 moves at the position close to the inclined guide plate 8, it drives the distributed outer sleeve 18 and inner sliding tube 29 to be close to the surface layer of the inclined guide plate 8, so as to facilitate the spherical nozzle 28 at the end of each inner sliding tube 29 to be inserted between the earth blocks, to facilitate the flushing of some dead angles or mutually covered positions, to improve the gravel flushing effect, and when the spherical nozzle 28 abuts against the stone block protrusion or the inclined guide plate 8, the inner sliding tube 29 will compress the third spring 32 and slide into the inner sleeve 18 due to the squeezing effect, which will cause the first linkage rod 30 and the second linkage rod 31 to be stretched, when the stone block protrusion is stuck and cannot move along the inclined guide plate 8, the first linkage rod 30 and the second linkage rod 31 can rely on the pushing effect of the stretching to prevent blockage, and during the reciprocating movement of the movable mounting plate 17, the spherical nozzle 28 can spray water from different height positions relative to the inclined guide plate 8, so as to facilitate the water flow to wash the stone block at multiple angle positions, and improve the flushing effect, because the height position between the spherical nozzle 28 and the inclined guide plate 8 is different when the earth blocks flow along the inclined guide plate 8, the angle position of the spherical nozzle 28 relative to the earth blocks will be different, and naturally it will also be washed at multiple angle positions.

[0051] It should be noted that even if one of the ball-shaped nozzles 28 directly contacts the slag block and cannot be lowered, the inner slide pipe 29 corresponding to the ball-shaped nozzle 28 is first squeezed into the outer sleeve pipe 18 during the process, and then the outer sleeve pipe 18 slides upward relative to the movable mounting plate 17 due to the downward pressure, and the second spring 37 is stretched, thereby avoiding affecting the lowering of the ball-shaped nozzles 28 at other positions into the gap between the slag blocks.

[0055] Secondly, the initial screening and conveying mechanism of each group of screening boxes 2 conveys the remaining slag to the corresponding washing transition bearing mechanism, and relies on the linkage washing mechanism to wash the slag, so as to wash the sand and gravel attached to the surface of the large stone blocks or soil blocks screened out, and the washed sand and gravel and water can be discharged and collected and further treated for recycling, and the large stone blocks or soil blocks washed can be conveniently subjected to subsequent related recycling treatment.

[0056] Thirdly, during the operation of the initial screening and conveying mechanism of each group of screening boxes 2, the initial screening and conveying mechanism respectively drives the corresponding linkage washing mechanism to move by means of the corresponding driving transmission mechanism, so as to improve the washing effect.

[0057] In order to facilitate the understanding of the person skilled in the art to the embodiment of the present scheme, the working principle of the present scheme will be briefly described in combination with a specific application scenario:

[0058] Firstly, the slag is put into the uppermost sieve box 2, the driving motor 14 on the outer wall of the sieve box 2 drives the corresponding synchronous wheel 13 to rotate, then the synchronous wheel 13 drives all the synchronous wheels 13 to rotate through the synchronous belt 12, so that all the transmission rollers 3 rotate synchronously in the same direction, thereby facilitating the transmission and conveying of the slag, and the slag smaller than the interval between adjacent transmission rollers 3 falls into the next sieve box 2 for screening, and the screening is sequentially performed, finally the fine sand and gravel falls onto the first conveyor belt mechanism 9 on the supporting base 1 and is conveyed out, and the screened slag in each sieve box 2 is conveyed to the inclined guide plate 8 by the corresponding transmission roller 3, and then slides to the discharge port 4 along the inclined guide plate 8.

[0059] When the synchronous wheel 13 moves, it drives the driving gear 26 to rotate, the driving gear 26 drives the linkage gear 20 to rotate through the transmission gear 27, so that the cam 21 rotates, the cam 21 constantly pushes the baffle 22 in the rotating process, the baffle 22 drives the movable mounting plate 17 to move towards the inclined guide plate 8 through the guide rod 23, in this process, the first spring 25 is stretched to generate a rebound force, when the cam 21 is separated from the baffle 22, the guide rod 23 carries the movable mounting plate 17 to reset under the action of the rebound force of the first spring 25, thereby facilitating the reciprocating movement of the movable mounting plate 17;

[0060] During the reciprocating movement of the movable mounting plate 17, the distributed outer sleeve 18 and the inner slide pipe 29 are synchronously moved, the water pump 5 delivers the water in the water tank 15 into each outer sleeve 18, then the water flow is sprayed out through the ball-shaped spray head 28 at the end of the inner slide pipe 29, which facilitates the flushing of the sludge on the inclined guide plate 8, and when the movable mounting plate 17 approaches the position of the inclined guide plate 8, the distributed outer sleeve 18 and the inner slide pipe 29 approach the surface layer of the inclined guide plate 8, which facilitates the insertion of the ball-shaped spray head 28 at the end of each inner slide pipe 29 between the sludge blocks, facilitates the flushing of some dead angles or positions covered and shielded by each other, improves the gravel flushing effect, and when the ball-shaped spray head 28 abuts against the stone block protrusion or the inclined guide plate 8, the inner slide pipe 29 is compressed by the third spring 32 and slides into the outer sleeve 18 due to the extrusion effect, which causes the first linkage rod 30 and the second linkage rod 31 to be spread open, when the stone block protrusion is stuck and cannot move along the inclined guide plate 8, the first linkage rod 30 and the second linkage rod 31 can rely on the pushing effect of the sludge block to prevent blockage, and during the reciprocating movement of the movable mounting plate 17, the ball-shaped spray head 28 can spray water from different height positions relative to the inclined guide plate 8, which facilitates the water flow to flush the stone block at multiple angle positions, improves the flushing effect, and finally the mud water produced by the flushing of the gravel passes through the strip-shaped water leakage hole 11, then enters the transition chamber 33, then flows along the auxiliary guide plate 34 to the discharge port for discharge, and enters the sedimentation tank 16 for sedimentation, then the layered water is pumped away, and the sedimented sludge is taken out for drying, so as to facilitate reuse, and the remaining screened sludge can be used for other purposes.

[0061] The above describes several embodiments of the present application in detail, but the embodiments of the present application are not limited thereto, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made according to the scope of the present application should still belong to the scope of the present application.
