Description

Technical Field

[0001] The present invention relates to the technical field of high-temperature molten slag removal equipment, and particularly relates to a belt slag removal machine. Background Art

[0002] The belt slag removal machine is mainly used for transporting a large amount of water-quenched slag generated after high-temperature melting. It is a device that realizes the scooping and transportation of water-quenched slag through a belt transportation method.

[0003] The belt slag removal machine mainly consists of a slag scooping bucket, a conveyor belt, a driving device, a support structure, a control system, etc. Among them, the slag scooping bucket is responsible for scooping 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 a designated position. When the water-quenched slag falls into the slag scooping pool of the slag removal machine through a chute during operation, the digging bucket in the slag removal machine scoops up the water-quenched slag. Subsequently, the driving device starts, driving the conveyor belt to operate, and transporting the water-quenched slag to a designated slag bin or treatment equipment along a predetermined path by using centrifugal force.

[0004] However, the existing slag removal machines usually scoop up a large amount of water during the slag scooping process, which easily causes the water-quenched slag to overflow with the water flow in the slag scooping bucket and also greatly consumes the transmission power of the belt conveyor. Summary of the Invention

[0005] The purpose of the present invention is to provide a belt slag removal machine to solve the problems in the prior art that the slag scooping bucket scoops up water and water-quenched slag simultaneously, resulting in additional consumption of transmission power, easy blockage of filter plates or filter holes during slag scooping and filtering, and poor water filtering effect of the slag scooping bucket.

[0006] To solve the above technical problems, the present invention specifically provides the following technical solutions:

[0007] The present invention provides a belt slag removal machine, including: a conveyor belt, which is driven by driving wheels provided at both ends, and the conveyor belt is vertically arranged relative to the slag scooping pool; a support ring plate, which is U-shaped and surrounds the lower half of the conveyor belt. A slag guiding channel is provided on one side of the support ring plate for introducing water-quenched slag to the inner bottom of the support ring plate. Drainage holes I are opened on the support ring plate, and at least one drainage hole I is provided in the middle of the inner bottom of the support ring plate; a plurality of slag scooping buckets are equidistantly arranged on the conveyor belt, and the slag scooping buckets are used for scooping water-quenched slag in the support ring plate; a folding plate is provided on the inner bottom of the support ring plate. The folding plate includes a long plate and a short plate. Filter holes are opened on the long plate. One end of the long plate is hinged to the support ring plate, the other end of the long plate is hinged to one end of the short plate, and a roller is provided at the other end of the short plate. The roller is in rolling contact with the inner bottom surface of the support ring plate. A torsion spring is provided at the hinge between the long plate and the short plate so that the folding plate can reset after movement; guide wheels are provided on both sides of the bucket end of the slag scooping bucket. During the process of the conveyor belt driving the slag scooping bucket to rotate, the guide wheels press down the long plate accordingly.

[0008] Furthermore, the support ring plate includes a side plate and a bottom plate. The bottom plate is in a semi-circular arc shape, the side plate is arranged in contact with the bottom plate along the tangent direction of the end of the bottom plate, and the bottom plate is a porous plate structure.

[0009] Furthermore, one end of the slag guiding channel communicates with the support ring plate, the other end of the slag guiding channel is arranged in an inclined shape, and the inclined direction of the slag guiding channel is opposite to the direction of gravity.

[0010] Furthermore, the wheel axle of the guiding wheel is arranged on the side wall of the slag ladle, and the wheel circumference of the guiding wheel protrudes beyond the edge of the end of the slag ladle, so that there is a gap between the edge of the end of the slag ladle and the long plate when the guiding wheel rolls along the long plate.

[0011] Furthermore, there is a gap between adjacent folding plates to provide a moving space for the rollers on the short plate.

[0012] Furthermore, through holes are provided on the support ring plate, an arc-shaped flow-through plate is arranged outside the support ring plate, anchor rods are provided on the flow-through plate, and the anchor rods penetrate through to the through holes. During the process of the folding plate being flattened under force, the anchor rods can be inserted into the filter holes of the long plate.

[0013] Furthermore, the length of the anchor rod protruding from the support ring plate is proportional to the distance between the long plate and the support ring plate.

[0014] Furthermore, a second drain hole is provided on the side wall of the slag ladle, the second drain hole is arranged close to the bottom of the slag ladle, and a guide plate inclined downward in the direction of gravity is arranged outside the second drain hole.

[0015] Furthermore, a second drain hole is provided on the side wall of the slag ladle, the second drain hole is arranged close to the bottom of the slag ladle, and the mouth of the slag ladle is inclined inward and gathered by 20°.

[0016] Furthermore, a movable sphere is embedded in the second drain hole, a gap is left between the movable sphere and the second drain hole for water flow to pass through, and the movable sphere generates vertical displacement in the second drain hole as the opening direction of the slag ladle changes.

[0017] The present invention has the following beneficial effects compared with the prior art:

[0018] The present invention retrieves the granulated slag in the slag pool by the method of filtering water first and then retrieving slag. At the same time, while the slag ladle lifts the granulated slag, further water filtering operation is carried out inside the slag ladle, which can effectively reduce the power and energy consumption of the driving wheel driving the conveyor belt, and can also avoid the driving wheel at the lower end of the equipment being soaked in water for a long time, increasing the failure rate, and improving the stability, durability and slag retrieval efficiency of the equipment.

[0019] Through the arrangement of the supporting ring plate, the present device utilizes the flowing water to enable the water quenched slag to enter the supporting ring plate for collection, while allowing the water body to flow out. Then, several slag buckets that continuously rotate in a cycle are used to centrally retrieve the water quenched slag with less water content. During the slag retrieval process, through the arrangement of the folding plate on the inner side wall of the supporting ring plate, the water quenched slag can be made to flow intermittently, preventing the water quenched slag from accumulating concentratedly at a certain place on the supporting ring plate, which is not conducive to the slag bucket for digging, resulting in a reduction in the slag retrieval amount in each slag bucket and affecting the slag retrieval efficiency.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] As Figure 1 shown, the present invention provides a belt slag scraper, including:

[0035] A conveying belt 1, which is driven by driving wheels 11 provided at both ends thereof, and the conveying belt 1 is vertically arranged relative to the slag scraper pit;

[0036] A support ring plate 2, which is in a U shape and surrounds the lower half of the conveying belt 1. A slag guiding channel 21 is provided on one side of the support ring plate 2, and the slag guiding channel 21 is used to introduce the water-quenched slag to the inner bottom of the support ring plate 2. A first drainage hole 22 is opened on the support ring plate 2, and at least one first drainage hole 22 is provided in the middle of the inner bottom of the support ring plate 2;

[0037] Slag ladles 3 are provided at equal intervals on the conveying belt 1, and the slag ladles 3 are used to dig the water-quenched slag in the support ring plate 2;

[0038] In this embodiment, more specifically, a folding plate 23 is provided on the inner bottom of the support ring plate 2. The folding plate 23 includes a long plate 231 and a short plate 232. Filter holes 233 are opened on the long plate 231. One end of the long plate 231 is hinged to the support ring plate 2, the other end of the long plate 231 is hinged to one end of the short plate 232, and a roller 234 is provided at the other end of the short plate 232. 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 joint between the long plate 231 and the short plate 232 so that the folding plate 23 can reset after movement; Guide wheels 31 are provided on both sides of the bucket end of the slag ladle 3. During the process that the conveying belt 1 drives the slag ladle 3 to rotate, the guide wheels 31 press down the long plate 231 accordingly.

[0039] A belt slag scraper provided by the present invention retrieves the water-quenched slag in the slag pool by first filtering water and then scraping slag. At the same time, while the slag scraping bucket 3 lifts the water-quenched slag, further water filtering operation is carried out inside the slag scraping bucket 3, which can effectively reduce the power and energy consumption of the driving wheel 11 driving the conveyor belt 1, and can also avoid the driving wheel 11 at the lower end of the equipment being soaked in water for a long time, increasing the failure rate, and improving the stability, durability and slag scraping efficiency of the equipment. Specifically, through the setting of the support ring plate 2, the flowing water flow is used to make the water-quenched slag enter the support ring plate 2 for collection, and at the same time the water body flows out, and then several continuously circulating and rotating slag scraping buckets 3 are used to centrally scrape the water-quenched slag with less water content. During the slag scraping process, through the setting of the folding plate 23 on the inner side wall of the support ring plate 2, the water-quenched slag can be in an intermittent flowing state, avoiding the water-quenched slag from concentrating and piling up at a certain place on the support ring plate 2, and it is not easy for the slag scraping bucket 3 to dig, resulting in a reduction in the slag scraping amount in each slag scraping bucket 3 and affecting the slag scraping efficiency.

[0040] In this embodiment, more specifically, when the guide wheel 31 at the end of the slag scraping bucket 3 touches the long plate 231, the guide wheel 31 presses it down along the path of the long plate 231 until the folding plate 23 is completely unfolded on the inner side wall of the support ring plate 2. During this process, since the bucket end of the slag scraping bucket 3 always adheres to the long plate 231, it is easier to shovel up the water-quenched slag piled up on the long plate 231, and the digging amount can be increased. It should be noted that the structural shapes of the long plate 231 and the support ring plate 2 can be adaptively designed. For example, the long plate 231 can be an arc-shaped plate to fit on the arc-shaped support ring plate 2; a part of the support ring plate 2 can also be set as a straight plate shape so that the straight plate-shaped long plate 231 can fit on it. By reducing the gap between the long plate 231 and the support 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.

[0041] More specifically, please continue to refer to Figure 2 As shown, the support ring plate 2 includes a side plate 24 and a bottom plate 25. The bottom plate 25 is in a semi-circular arc shape, and the side plate 24 is connected to it along the tangential direction of the end of the bottom plate 25. The bottom plate 25 is a porous plate structure.

[0042] In this embodiment, through the design of the semi-circular arc-shaped bottom plate 25, it can be adapted to the movement path of the slag scraping bucket 3, so that the folding plate 23 is on the movement path of the slag scraping bucket 3, so as to form a linkage between the two. Also, through the porous structure design of the bottom plate 25, the water-quenched slag collected on the bottom plate 25 can be drained, avoiding the accumulation of water flow and increasing the slag scraping energy consumption, affecting the operation of the conveyor belt 1, and ensuring the stability of the water-quenched slag retrieved in the slag scraping bucket 3.

[0043] More specifically, please continue to 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.

[0044] In this embodiment, by arranging the slag guiding channel 21 on one side of the supporting ring plate 2, the water-quenched slag can enter the inside of the supporting ring plate 2 along with the flowing water. The inclination degree of the slag guiding channel 21 is determined according to the actual use situation, aiming to adapt to the position of the slag skimming pit and ensure that the water-quenched slag can smoothly enter the supporting ring plate 2.

[0045] In the above embodiment, in order to improve the slag skimming efficiency, the distance between the end of the slag skimming bucket 3 and the long plate 231 is often set as small as possible. However, due to the too-close distance, the water-quenched slag is driven by the front edge of the end of the slag skimming bucket 3 into the filter holes 233 on the long plate 231, causing the filter holes 233 to be blocked and reducing the overall water filtering capacity inside the supporting ring plate 2.

[0046] To solve the above problems, please refer to Figure 3-4 As shown, in the 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 skimming bucket 3, and the circumference of the guide wheel 31 protrudes from the edge of the end of the slag skimming bucket 3, so that there is a gap between the edge of the end of the slag skimming bucket 3 and the long plate 231 when the guide wheel 31 rolls along the long plate 231.

[0047] In this embodiment, by using the guide wheel 31 to replace the direct contact between the slag skimming bucket 3 and the long plate 231, a gap can be reserved between the edge of the end of the slag skimming bucket 3 and the long plate 231, reducing the number of blocked 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 opened on the long plate 231 to limit the guide wheel 31 and prevent the guide wheel 31 from slipping out.

[0048] More specifically, in order to enable the folding plate 23 to completely cover the supporting ring plate 2 after unfolding, please continue to refer to Figure 3 As shown, there is a gap between adjacent folding plates 23 to provide a moving space for the rollers 234 on the short plate 232.

[0049] In the above embodiment, as the carrier for the water-quenched slag, the filter holes 233 on the long plate 231 are easily blocked due to the long-term accumulation of the water-quenched slag, which will affect the water filtering efficiency of the long plate 231.

[0050] To solve the above problems, as shown in Figure 3As shown in the figure, in the preferred embodiment provided by the present invention based on the above-mentioned embodiment, the support ring plate 2 is provided with a through hole 26, and an arc-shaped flow-through plate 27 is arranged outside the support ring plate 2. A needle rod 271 is arranged on the flow-through plate 27, and the needle rod 271 penetrates through to the through hole 26. During the process of the folding plate 23 being flattened under force, the needle rod 271 can be inserted into the filter hole 233 of the long plate 231.

[0051] 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.

[0052] In this embodiment, the needle rod 271 arranged outside the support ring plate 2 can dredge the filter holes 233 on the long plate 231. It should be noted that since the long plate 231 makes a circular motion under force, the arrangement of the needle rod 271 may affect the rotation of the long plate 231. 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.

[0053] In the above-mentioned embodiment, since the plurality of slag scoops 3 are arranged in sequence, and in order to filter the water in the slag scoop 3, the bottom of the slag scoop 3 needs to be set as a hollow structure. When the slag is lifted, the water leakage from the slag scoop 3 above will enter the slag scoop 3 below. The untimely discharge of water will lead to a reduction in the water filtration efficiency, and it is also easy to cause the water-quenched slag to overflow with the water flow due to excessive water storage in the slag scoop 3 below.

[0054] To solve the above problems, as Figure 4-6 shown, in the preferred embodiment provided by the present invention based on the above-mentioned embodiment, a second drainage hole 32 is arranged 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, and a guide plate 33 inclined downward in the direction of gravity is arranged outside the second drainage hole 32.

[0055] In this embodiment, through the arrangement of the second drainage hole 32 and the guide plate 33, the discharge path of the water flow is changed, thereby improving the water filtration efficiency and avoiding the problem that the water-quenched slag overflows with the water flow due to excessive water storage in the slag scoop 3 below.

[0056] In another embodiment provided by the present invention, a second drainage hole 32 is arranged 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, and the mouth of the slag scoop 3 is inclined inward by 20°.

[0057] In this embodiment, through the arrangement that the mouth of the slag scoop 3 is inclined inward by 20°, the water flow discharged from the second drainage hole 32 above can first fall on the inclined side wall of the slag scoop 3 below, avoiding the water flow directly falling into the interior of the slag scoop 3 and mixing with the water-quenched slag, and improving the water filtration efficiency.

[0058] In the above embodiments, the second drain hole 32 may be blocked due to the outflow of the crushed water-quenched slag, resulting in the problem of too small drainage volume.

[0059] To solve the above problems, as Figure 5-6 shown, in the preferred embodiment provided by the present invention based on the above embodiments, a movable sphere 34 is embedded in the second drain hole 32, and a gap is left between the movable sphere 34 and the second drain hole 32 for water flow to pass through. The movable sphere 34 generates vertical displacement in the second drain hole 32 as the opening direction of the slag ladle 3 changes.

[0060] In this embodiment, by arranging the movable sphere 34 in the second drain hole 32, the position of the water-quenched slag blocking in the second drain hole 32 can be changed through the movement of the movable sphere 34, thereby dredging the blockage. Specifically, when the slag ladle 3 moves upward, the movable sphere 34 is in the half area of the second drain hole 32 under the action of gravity; when the slag ladle 3 moves downward, the whole slag ladle 3 is inverted, and the movable sphere 34 is in the other half area of the second drain hole 32 under the action of gravity, so as to avoid the water-quenched slag stuffed in the second drain hole 32 for a long time and being difficult to be flushed out.

[0061] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
