[0001] The invention relates to the technical field of high-temperature melting slag scooping equipment, and in particular to a belt slag scooping machine. Background Art

[0002] The belt slag scoop machine is mainly used to transport a large amount of water-quenched slag produced after high-temperature melting. It is a device that uses belt conveyor to scoop and transport water-quenched slag.

[0003] The belt slag scoop mainly consists of a slag scoop bucket, a conveyor belt, a drive device, a support structure, a control system and other parts. Among them, the slag scoop bucket is responsible for scooping the water-quenched slag from the bottom of the slag pool or the slag outlet, and the conveyor belt is responsible for transporting the scooped water-quenched slag to the designated location. When the belt slag scoop is working, when the water-quenched slag falls into the slag scoop pool of the slag scoop machine through the chute, the bucket in the slag scoop machine scoops up the water-quenched slag. Subsequently, the drive device starts, driving the conveyor belt to operate, and the water-quenched slag is transported to the designated slag bin or processing equipment along the predetermined path using centrifugal force.

[0004] However, the existing slag scooping machine usually scoops up a large amount of water during the slag scooping process, which easily causes the water-quenched slag to overflow from the slag scooping bucket along with the water flow, and also greatly consumes the transmission power of the belt conveyor.

[0008] Furthermore, one end of the slag guiding channel is connected to the supporting ring plate, and the other end of the slag guiding channel is arranged in an inclined shape, and the inclination direction of the slag guiding channel is opposite to the direction of gravity.

[0009] Furthermore, the axle of the guide wheel is arranged on the side wall of the slag bucket, and the wheel circumference of the guide wheel is arranged to protrude from the edge of the slag bucket end, so that when the guide wheel rolls along the long board, a gap is left between the edge of the slag bucket end and the long board.

[0010] Furthermore, a spacing is left between adjacent folding plates to provide a movable space for the rollers on the short plates.

[0011] Furthermore, a through hole is provided on the support ring plate, an arc-shaped flow plate is provided on the outer side of the support ring plate, a needle rod is provided on the flow plate, the needle rod penetrates into the through hole, and the needle rod can be inserted into the filter hole of the long plate during the process of the folding plate being flattened by force.

[0017] The device uses the support ring plate to make the water-quenched slag enter the support ring plate for collection by using the flowing water flow, and at the same time makes the water flow out, and then collects the water-quenched slag with less water content through several slag buckets that continuously circulate and rotate. During the slag collection process, the folding plate on the inner wall of the support ring plate can make the water-quenched slag present an intermittent flow state, avoiding the water-quenched slag from being concentrated and accumulated in a certain place on the support ring plate, which makes it difficult for the slag bucket to dig it out, resulting in a reduction in the slag amount in each slag bucket, affecting the slag collection efficiency.

[0021] 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.

[0022] like Figure 1 As shown, the present invention provides a belt slag scooping machine, comprising: A conveyor belt 1, with driving wheels 11 at both ends for driving, and the conveyor belt 1 is arranged vertically relative to the slag scooping pool; The support ring plate 2 is U-shaped and surrounds the lower half of the conveyor belt 1. A slag guide channel 21 is provided on one side of the support ring plate 2. The slag guide channel 21 is used to introduce water-quenched slag into the inner bottom of the support ring plate 2. A drainage hole 22 is provided on the support ring plate 2. The drainage hole 22 is at least provided in the middle of the inner bottom of the support ring plate 2. A plurality of slag scoops 3 are equidistantly arranged on the conveyor belt 1, and the slag scoops 3 are used to dig out the water-quenched slag in the supporting ring plate 2; In this embodiment, more specifically, a folding plate 23 is provided on the inner bottom of the support ring plate 2, and the folding plate 23 includes a long plate 231 and a short plate 232. A filter hole 233 is opened on the long plate 231, one end of the long plate 231 is hinged to the support ring plate 2, and the other end of the long plate 231 is hinged to one end of the short plate 232. A roller 234 is provided at the other end of the short plate 232, and the roller 234 is in rolling contact with the inner bottom surface of the support ring plate 2. A torsion spring is provided at the hinge between the long plate 231 and the short plate 232 so that the folding plate 23 can be reset after movement; guide wheels 31 are provided on both sides of the bucket end of the slag bucket 3, and when the conveying belt 1 drives the slag bucket 3 to rotate, the guide wheels 31 press down the long plate 231 accordingly.

[0023] The belt slag scooping machine provided by the present invention scoops the water-quenched slag in the slag pool by filtering water first and then scooping slag. At the same time, while the slag scooping bucket 3 lifts the water-quenched slag, further water filtering is performed inside the slag scooping bucket 3, which can effectively reduce the power and energy consumption of the driving wheel 11 driving the conveying belt 1, and can also avoid the driving wheel 11 at the lower end of the equipment from being soaked in water for a long time to increase the failure rate, thereby improving the stability, durability and slag scooping efficiency of the equipment. Specifically, the device uses the flowing water flow through the support ring plate 2 to make the water-quenched slag enter the support ring plate 2 for collection, and at the same time makes the water flow out, and then the water-quenched slag with less water content is concentratedly scooped through several slag scooping buckets 3 that continuously circulate and rotate. During the slag scooping process, the folding plate 23 is set on the inner wall of the support ring plate 2, so that the water-quenched slag can be in an intermittent flow state, avoiding the water-quenched slag from being concentrated and accumulated somewhere on the support ring plate 2, and not being easy for the slag scooping bucket 3 to dig, resulting in a reduction in the slag scooping amount in each slag scooping bucket 3, affecting the slag scooping efficiency.

[0024] In this embodiment, more specifically, when the guide wheel 31 at the end of the slag bucket 3 contacts the long plate 231, the guide wheel 31 follows the path of the long plate 231 and presses it down until the folding plate 23 is fully unfolded on the inner wall of the supporting ring plate 2. In this process, since the bucket end of the slag bucket 3 is always close to the long plate 231, it is easier to shovel the water-quenched slag accumulated on the long plate 231, which can increase the amount of scooping. It should be noted that the structural shapes of the long plate 231 and the supporting ring plate 2 can be adaptively designed, for example: the long plate 231 can be an arc-shaped plate so that it can fit on the arc-shaped supporting ring plate 2; a part of the supporting ring plate 2 can also be set to a straight plate shape so that the straight plate-shaped long plate 231 can fit thereon. By reducing the gap between the long plate 231 and the supporting ring plate 2, it is possible to prevent the water-quenched slag from entering between the two, so as to avoid affecting the movement of the folding plate 23.

[0025] For more details, please refer to Figure 2 As shown, the supporting ring plate 2 includes a side plate 24 and a bottom plate 25. The bottom plate 25 is in a semicircular arc shape. The side plate 24 is connected to the bottom plate 25 along the tangent direction of the end thereof. The bottom plate 25 is a porous plate structure.

[0026] In this embodiment, the semicircular bottom plate 25 is designed to be compatible with the movement path of the slag bucket 3, so that the folding plate 23 is located on the movement path of the slag bucket 3, so that the two are linked. The porous structure of the bottom plate 25 is also designed to drain the water-quenched slag collected on the bottom plate 25, so as to avoid water accumulation and increase the slag scooping energy consumption, affecting the operation of the conveyor belt 1, and also ensure the stability of the water-quenched slag scooped in the slag bucket 3.

[0027] For more details, please refer to Figure 1-2As shown, one end of the slag guiding channel 21 is connected to the supporting ring plate 2, and the other end of the slag guiding channel 21 is arranged in an inclined shape, and the inclined direction of the slag guiding channel 21 is opposite to the direction of gravity.

[0028] In this embodiment, by providing a slag guiding channel 21 on one side of the support ring plate 2, the water-quenched slag can enter the support ring plate 2 along with the flowing water. The inclination of the slag guiding channel 21 is determined according to actual usage conditions, so as to adapt to the position of the slag scooping pool and ensure that the water-quenched slag can smoothly enter the support ring plate 2.

[0029] In the above embodiment, in order to improve the slag scooping efficiency, the distance between the end of the slag scoop 3 and the long plate 231 is often set as small as possible. However, if the distance is too close, the water-quenched slag will be driven into the filter hole 233 on the long plate 231 by the front edge of the end of the slag scoop 3, causing the filter hole 233 to be blocked, thereby reducing the overall water filtering capacity inside the support ring plate 2.

[0030] To solve the above problems, see Figure 3-4 As shown, in a preferred embodiment provided by the present invention based on the above embodiment, the axle of the guide wheel 31 is arranged on the side wall of the slag bucket 3, and the wheel circumference of the guide wheel 31 protrudes from the edge of the bucket end of the slag bucket 3, so that when the guide wheel 31 rolls along the long plate 231, a gap is left between the edge of the bucket end of the slag bucket 3 and the long plate 231.

[0031] In this embodiment, the guide wheel 31 replaces the direct contact between the slag bucket 3 and the long plate 231, so that a gap can be reserved between the bucket end edge of the slag bucket 3 and the long plate 231, thereby reducing the number of blockages of the filter holes 233. It should be noted that in order to ensure the stability of the guide wheel 31 rolling on the long plate 231, a shallow groove can be provided on the long plate 231 to limit the guide wheel 31 and prevent the guide wheel 31 from falling out.

[0032] More specifically, in order to enable the folding plate 23 to completely cover the supporting ring plate 2 after being unfolded, please continue to refer to Figure 3 As shown, there is a gap between adjacent folding plates 23 to provide movement space for the rollers 234 on the short plates 232 .

[0033] In the above embodiment, the long plate 231 is used as a carrier for the water-quenched slag, and the filter holes 233 thereon are easily clogged due to the long-term accumulation of the water-quenched slag, which will affect the water filtering efficiency of the long plate 231 .

[0034] In order to solve the above problems, Figure 3As shown, in a preferred embodiment provided by the present invention based on the above-mentioned embodiment, a through hole 26 is provided on the support ring plate 2, an arc-shaped flow plate 27 is provided on the outer side of the support ring plate 2, a needle rod 271 is provided on the flow plate 27, and the needle rod 271 penetrates through the through hole 26. During the process of the folding plate 23 being flattened by force, the needle rod 271 can be inserted into the filter hole 233 of the long plate 231.

[0035] More specifically, in order to ensure that the needle rod 271 can enter the through hole 26 , the length of the needle rod 271 protruding from the support ring plate 2 is proportional to the distance between the long plate 231 and the support ring plate 2 .

[0036] In this embodiment, the filter hole 233 on the long plate 231 can be cleared by the needle rod 271 disposed on the outer side of the supporting ring plate 2. It should be noted that since the long plate 231 performs a circular motion under force, the setting of the needle rod 271 may affect the rotation of the long plate 231. In order to solve this problem, the end of the needle rod 271 can be arc-shaped and can be made of non-rigid rubber material so as to be able to enter the filter hole 233.

[0037] In the above embodiment, since a plurality of slag hoppers 3 are arranged in sequence, in order to filter out the water in the slag hopper 3, it is necessary to set the bottom of the slag hopper 3 as a hollow structure. When the slag is lifted, water leakage from the slag hopper 3 located above will enter the slag hopper 3 located below. The untimely discharge of water will lead to a decrease in the water filtering efficiency, and it is also easy to cause the slag hopper 3 located below to overflow with the water flow due to excessive water storage.

[0038] In order to solve the above problems, Figure 4-6 As shown, in a preferred embodiment provided by the present invention based on the above embodiment, a second drainage hole 32 is provided on the side wall of the slag hopper 3, the second drainage hole 32 is arranged close to the bottom of the slag hopper 3, and a guide plate 33 inclined downward in the direction of gravity is provided on the outer side of the second drainage hole 32.

[0039] In this embodiment, the second drainage hole 32 and the guide plate 33 are provided to change the discharge path of the water flow, thereby improving the water filtering efficiency and avoiding the problem that the water-quenched slag overflows with the water flow due to excessive water storage in the slag hopper 3 located below.

[0040] In another embodiment provided by the present invention, a second drainage hole 32 is provided on the side wall of the slag scoop 3. The second drainage hole 32 is arranged close to the bottom of the slag scoop 3. The mouth of the slag scoop 3 is inclined inwardly at 20 degrees.

[0041] In this embodiment, by setting the mouth of the slag hopper 3 to be gathered inward and tilted at 20°, the water discharged from the second drainage hole 32 located at the top can first fall on the inclined side wall of the slag hopper 3 located at the bottom, avoiding the water flow directly falling into the interior of the slag hopper 3 and mixing with the water-quenched slag, thereby improving the water filtration efficiency.

[0042] In the above embodiment, the second drainage hole 32 may be blocked due to the outflow of water-quenched slag fragments, resulting in a problem of too little drainage.

[0043] In order to solve the above problems, Figure 5-6 As shown, in a preferred embodiment provided by the present invention based on the above embodiment, a movable ball 34 is embedded in the second drainage hole 32, and a gap is left between the movable ball 34 and the second drainage hole 32 for water to flow through. The movable ball 34 produces an up and down displacement in the second drainage hole 32 as the opening direction of the slag bucket 3 changes.

[0044] In this embodiment, by arranging the movable ball 34 in the second drainage hole 32, the position of the water-quenched slag blocked in the second drainage hole 32 can be changed by the movement of the movable ball 34, thereby clearing the blockage. Specifically, when the slag bucket 3 moves upward, the movable ball 34 is in the half area of ​​the second drainage hole 32 due to the action of gravity; when the slag bucket 3 moves downward, the slag bucket 3 is turned upside down as a whole, and the movable ball 34 is in the other half area of ​​the second drainage hole 32 due to the action of gravity, thereby preventing the blocked water-quenched slag from being in the second drainage hole 32 for a long time and being difficult to be flushed out.

[0045] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
