Description

Technical Field

[0001] The invention relates to the technical field of industrial waste residue treatment, in particular to an industrial waste residue unloading device. Background Art

[0002] Industrial waste slag refers to solid waste generated in the process of industrial production. It has a wide range of sources, including ore smelting, chemical, coal and petrochemical production activities. It is characterized by large discharge volume, wide variety and complex composition.

[0003] In the production activities of ore smelting, a large amount of slag is generated. These slags need to be loaded, transported and unloaded when used. In the unloading process, unloading equipment is needed. In the related technology, for example, Chinese patent CN113003257B discloses a dust reduction ash and soil slag bin unloading system. When the dust reduction ash and soil slag bin unloading system is in use, the waste slag is in a relatively closed environment of an aggregate box. Therefore, after unloading, the material guide pipe is removed from the feed port and the feed port is sealed. The stacked waste slag is not easy to generate dust in the aggregate box due to wind and other reasons.

[0004] Although the existing waste slag unloading equipment can realize the unloading of industrial waste slag, it is found in actual use that since waste slag of different sizes have different subsequent treatment methods and final uses, the waste slag needs to be classified and processed according to different sizes after unloading. However, the existing waste slag unloading equipment cannot classify and process the waste slag while unloading, which affects the treatment efficiency of industrial waste slag. Summary of the invention

[0005] Based on this, it is necessary to provide an industrial waste slag unloading device to address the problem of low treatment efficiency in the current industrial waste slag treatment process.

[0007] Preferably, the industrial waste slag unloading device further comprises a swing mechanism, and the swing mechanism is configured to provide a driving force for the push rod to swing back and forth at a variable speed around the end of its second end.

[0008] Preferably, the swing mechanism includes a support arm, a swing arm and a rotating rod, the support arm is horizontally and fixedly arranged on the frame; the swing arm is inclined and located above the support arm; the two ends of the top rod are respectively hinged to the two ends on the same side of the support arm and the swing arm; the two ends of the rotating rod are respectively hinged to the two ends on the other side of the support arm and the swing arm; the rotating rod can rotate around its own hinge point on the support arm.

[0009] Preferably, the swing mechanism further comprises a first driving member, and the first driving member is configured to provide a driving force for the rotating rod to rotate around its hinge point on the support arm.

[0010] Preferably, the push rod can be extended and retracted along its own extension direction, so as to be in an extended state when the swing direction of the push rod is the same as the set conveying direction of the waste residue.

[0011] Preferably, the industrial waste slag unloading device further comprises a second driving member, and the second driving member is configured to provide a driving force for the extension and retraction of the top rod.

[0016] The beneficial effects of the present invention are: During use, the industrial waste slag unloading device disclosed by the present invention first puts a batch of waste slag onto the top of the conveyor belt. Since the waste slag can be divided into fine waste slag and coarse waste slag according to different sizes, when the waste slag falls onto the conveyor belt, the fine waste slag will mostly enter the classification trough due to its smaller size, while the coarse waste slag will stay on the top of two or more convex strips due to its larger size, so as to achieve preliminary separation; then the push rod is driven to swing back and forth with variable speed around the end of its second end, and in the process of the reciprocating variable speed swing of the push rod, through the cooperation between the clamping block and the clamping slot, when the swinging direction of the push rod is the same as the set conveying direction of the waste slag, the number of times the push rod drives the conveyor belt to move is A, and the average speed is V1, When the swing direction of the push rod is opposite to the set conveying direction of the waste slag, the number of times the push rod drives the conveyor belt to move is B, and the average speed is V2. Since V1>V2, when the push rod drives the conveyor belt to move quickly, the conveyor belt can synchronously drive the fine waste slag to move. The coarse waste slag has a larger size, larger mass and greater inertia, so that when the conveyor belt moves, the coarse waste slag can remain approximately motionless under the action of inertia; when the push rod drives the conveyor belt to move slowly, the conveyor belt synchronously drives the fine waste slag and the coarse waste slag to move. Since A>B, the fine waste slag and the coarse waste slag gradually move in opposite directions to achieve separation of waste slag while unloading, thereby improving the waste slag treatment efficiency.

[0022] like Figures 1 to 3As shown, the industrial waste slag unloading device provided by the embodiment of the present invention is configured to include a frame, on which a conveyor belt 1 and a push rod 2 are arranged, and the conveyor belt 1 forms a closed conveying loop on the frame; a plurality of convex strips 3 are arranged on the outer belt surface of the conveyor belt 1, and the convex strips 3 extend along the belt width direction of the conveyor belt 1, and the plurality of convex strips 3 are arranged at intervals along the belt length direction of the conveyor belt 1, and classification grooves 4 are formed between adjacent convex strips 3; a plurality of card grooves 5 are arranged on the inner belt surface of the conveyor belt 1, and the plurality of card grooves 5 are arranged at intervals along the belt length direction of the conveyor belt 1; the push rod 2 is located on the inner side of the conveyor belt 1, and the first end of the push rod 2 A card block 6 is inserted at the end of the push rod 2, and the card block 6 can slide along the extension direction of the push rod 2, and can form a card-fitting fit with the card slot 5 when the push rod 2 is extended, so as to drive the conveyor belt 1 to move; the push rod 2 can swing back and forth with variable speed around the end of its second end when in use, and when the swinging direction of the push rod 2 is the same as the set conveying direction of the waste slag, the number of times the push rod 2 drives the conveyor belt 1 to move is A, and the average speed is V1; when the swinging direction of the push rod 2 is opposite to the set conveying direction of the waste slag, the number of times the push rod 2 drives the conveyor belt 1 to move is B, and the average speed is V2, B<A, V2<V1.

[0023] Specifically in this embodiment, Figure 2 As shown, the shape of the conveyor belt 1 is set to be a rounded rectangle, and it is set horizontally during installation; in order to facilitate the support of the conveyor belt 1, two support rollers 8 are also provided on the frame, the two support rollers 8 are arranged at intervals, and the axes of the two support rollers 8 are set in parallel and located on the same horizontal plane. The conveyor belt 1 is simultaneously sleeved on the outside of the two support rollers 8 during installation.

[0024] The number of ridges 3 can be set to forty, and the forty ridges 3 are arranged at equal intervals along the belt length direction of the conveyor belt 1, and a total of forty classification grooves 4 are formed between the forty ridges 3; the number of card slots 5 can be set to thirty, and the thirty card slots 5 are arranged at equal intervals along the belt length direction of the conveyor belt 1.

[0025] like Figure 2 As shown, the extension direction of the top rod 2 points to the conveyor belt 1; Figure 3 As shown, the top end of the mandrel 2 is set as the first end, the bottom end is set as the second end, and the block 6 is installed on the top end of the mandrel 2; the set conveying direction of the waste slag is set to convey to the right.

[0026] In order to facilitate the centralized feeding of waste residues onto the top of the conveyor belt 1, a feed pipe 9 is also provided on the frame. Figure 1 As shown, the feed pipe 9 is configured as a square tube structure, and extends obliquely in the upper left direction, and is located at the upper left of the conveyor belt 1 .

[0027] During use, a batch of waste slag is first put into the left top of the conveyor belt 1 through the feed pipe 9. Since the waste slag can be divided into fine waste slag and coarse waste slag according to different sizes, when the waste slag falls onto the conveyor belt 1, most of the fine waste slag will enter the classification trough 4 due to its smaller size, and the coarse waste slag will stay on the top of two or more convex strips 3 due to its larger size to achieve preliminary separation.

[0028] Then it drives the push rod 2 to swing back and forth with variable speed around the bottom end; in the process of the push rod 2 swinging back and forth with variable speed, when the push rod 2 swings from the left extreme position to the right extreme position, the swing direction of the push rod 2 is the same as the set conveying direction of the waste slag, both are to the right, and the clamping block 6 is extended at this time and is engaged with the clamping slot 5, so that when the push rod 2 swings to the right, it can synchronously drive the conveyor belt 1 to move in the clockwise direction, and the average speed is V1; when the push rod 2 swings from the right extreme position to the left extreme position, the swing direction of the push rod 2 is opposite to the set conveying direction of the waste slag, and the clamping block 6 and the clamping slot 5 are still in the engaged state, so that when the push rod 2 swings to the left When swinging, it can drive the conveyor belt 1 to move in the counterclockwise direction, and the average speed is V2; when the push rod 2 swings from the left extreme position to the right extreme position again, the swing direction of the push rod 2 is the same as the set conveying direction of the waste slag, both are to the right, and the clamping block 6 and the clamping slot 5 are still in the clamping state, so that when the push rod 2 swings to the right, it can synchronously drive the conveyor belt 1 to move in the clockwise direction, and the average speed is V1; when the push rod 2 swings from the right extreme position to the left extreme position again, the swing direction of the push rod 2 is opposite to the set conveying direction of the waste slag, and the clamping block 6 retracts and disengages from the clamping slot 5, and the conveyor belt 1 remains stationary.

[0029] In the above process, since V1>V2, when the push rod 2 drives the conveyor belt 1 to move quickly to the right, the conveyor belt 1 can synchronously drive the fine waste slag to move, and the coarse waste slag is larger in size, thus having a larger mass and inertia, so that when the conveyor belt 1 moves, the coarse waste slag can remain approximately motionless under the action of inertia; when the push rod 2 drives the conveyor belt 1 to move slowly to the left, the conveyor belt 1 synchronously drives the fine waste slag and the coarse waste slag to move; and since it is a variable speed motion, it is beneficial to separate the fine waste slag and the coarse waste slag more thoroughly; and the fine waste slag moves to the right twice and to the left once, so that the fine waste slag as a whole still moves to the right; the coarse waste slag moves to the left once and does not move to the right, so that the coarse waste slag as a whole moves to the left.

[0030] The above process is repeated, so that the fine waste slag and the coarse waste slag gradually move in opposite directions, so as to separate the waste slag while unloading, thereby improving the waste slag treatment efficiency.

[0031] In a further embodiment, the industrial waste slag unloading device is configured to further include a swing mechanism 7, and the swing mechanism 7 is configured to provide a driving force for the top rod 2 to swing back and forth at a variable speed around the end of its second end.

[0032] Specifically in this embodiment, the swing mechanism 7 can be configured to include a support arm 701, a swing arm 702 and a rotating rod 703, wherein the support arm 701 is horizontally and fixedly arranged on the frame; the swing arm 702 is inclined and located above the support arm 701; the two ends of the top rod 2 are respectively hinged at the two ends on the same side of the support arm 701 and the swing arm 702; the two ends of the rotating rod 703 are respectively hinged at the two ends on the other side of the support arm 701 and the swing arm 702; the rotating rod 703 can rotate around its own hinge point on the support arm 701.

[0033] like Figure 2 As shown, the support arm 701, the swing arm 702 and the rotating rod 703 are all located on the inner side of the conveyor belt 1 during installation; Figure 3 As shown, the support arm 701 and the swing arm 702 are both configured as an I-shaped strip structure, the top end of the top rod 2 is hinged at the left end notch of the swing arm 702, and the bottom end is hinged at the left end notch of the support arm 701; the top end of the rotating rod 703 is hinged at the right end notch of the swing arm 702, and the bottom end is hinged at the right end notch of the support arm 701, the top rod 2, the support arm 701, the swing arm 702 and the rotating rod 703 together constitute a crank rocker mechanism, wherein the rotating rod 703 is a crank and the top rod 2 is a rocker.

[0034] When using, Figure 2 As shown, the rotating rod 703 is driven to rotate counterclockwise around its hinge point on the support arm 701; during the rotation of the rotating rod 703, the rotating rod 703 drives the push rod 2 to swing back and forth around the hinge point of the push rod 2 on the support arm 701 through the swing arm 702. Since the crank rocker mechanism has a quick return characteristic, the speed of the push rod 2 when swinging to the right is greater than the speed when swinging to the left, thereby making the average speed of the conveyor belt 1 when moving to the right greater than the average speed when moving to the left.

[0035] In a further embodiment, the swing mechanism 7 is configured to further include a first driving member, which is configured to provide a driving force for the rotating rod 703 to rotate around its hinge point on the support arm 701 .

[0036] Specifically in this embodiment, the first driving member is configured as a first driving motor 704, and the first driving motor 704 is mounted on a frame. Figure 3 As shown, the motor shaft of the first driving motor 704 is fixedly disposed on the bottom side wall of the rotating rod 703 , and the axis of the motor shaft of the first driving motor 704 coincides with the hinge point of the rotating rod 703 on the supporting arm 701 .

[0037] During use, the first drive motor 704 is started, and the first drive motor 704 drives the rotating rod 703 to rotate in a counterclockwise direction around its hinge point on the support arm 701.

[0038] In other embodiments, the swing mechanism 7 may also be configured to include a second drive motor 704 , which is mounted on a frame, and a motor shaft of the second drive motor 704 is fixedly disposed on a bottom end side wall of the top rod 2 .

[0039] During use, the second drive motor 704 is started. The speed of the second drive motor 704 gradually increases when the push rod 2 is driven to swing to the right, and the speed remains approximately unchanged when the push rod 2 is driven to swing to the left, so that the speed of the push rod 2 when swinging to the right is greater than the speed when swinging to the left, and thus the average speed of the conveyor belt 1 when moving to the right is greater than the average speed when moving to the left.

[0040] In other embodiments, in order to improve the separation efficiency of fine waste slag and coarse waste slag, the top rod 2 is configured to be able to extend and retract along its own extension direction, so that when the swing direction of the top rod 2 is the same as the set conveying direction of the waste slag, it is in an extended state.

[0041] Specifically in this embodiment, when the top rod 2 swings rapidly to the right, the top rod 2 is extended so that the top rod 2 can lift up part of the conveyor belt 1, making it more difficult for the coarse waste slag to move synchronously with the conveyor belt 1, thereby further improving the separation efficiency of the coarse waste slag and the fine waste slag.

[0042] In a further embodiment, the industrial waste slag unloading device is configured to further include a second driving member, and the second driving member is configured to provide a driving force for the extension and retraction of the top rod 2.

[0043] Specifically in this embodiment, the push rod 2 is configured as a split structure, and has a first part and a second part, wherein the first part is hinged to the swing arm 702, and the second part is hinged to the support arm 701; the second driving member is configured as a first driving cylinder, the first driving cylinder is inserted into the second part, and the axis of the output shaft of the first driving cylinder extends along a direction parallel to the extension direction of the push rod 2, and the output shaft of the first driving cylinder is fixedly arranged on the first part.

[0044] During use, when the push rod 2 swings rapidly to the right, the first drive cylinder is started, the output shaft of the first drive cylinder is extended, and the first part is synchronously driven to move away from the second part, so that the length of the push rod 2 increases.

[0045] It can be understood that the first driving cylinder can be configured as any one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0046] In other embodiments, the industrial waste slag unloading device is configured to further include a third driving member, and the third driving member is configured to provide a driving force for the block 6 to slide along the extension direction of the top rod 2.

[0047] Specifically in this embodiment, the third driving member is configured as a second driving cylinder, the second driving cylinder is inserted into the push rod 2, and the axis of the output shaft of the second driving cylinder extends along an extension direction parallel to the push rod 2, and the output shaft of the second driving cylinder is fixedly set on the clamping block 6.

[0048] During use, the second drive cylinder is started, the output shaft of the second drive cylinder extends, and synchronously drives the clamping block 6 to extend out of the push rod 2; the output shaft of the second drive cylinder retracts, and synchronously drives the clamping block 6 to retract into the push rod 2.

[0049] It can be understood that the second driving cylinder can be configured as any one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0050] In a further embodiment, when the push rod 2 is configured as a split structure, the second driving cylinder is inserted into the first part of the push rod 2 .

[0051] In other embodiments, the cross-sectional shape of the convex strip 3 is set to be U-shaped.

[0052] Specifically in this embodiment, the U-shaped convex strip 3 enables the fine waste residue to move more easily along the arc side wall of the convex strip 3 to the bottom of the classification trough 4.

[0053] In other embodiments, in order to make it easier for the card block 6 to be engaged with the card slot 5, the card slot 5 and the card block 6 are both configured as a bar structure.

[0054] Specifically in this embodiment, the clamping groove 5 extends along the belt width direction of the conveyor belt 1 and penetrates the belt side wall of the conveyor belt 1 .

[0055] In other embodiments, in order to reduce the dust generated during the waste slag unloading process from escaping into the external environment, the frame is configured to be a box structure, and the conveyor belt 1 is inserted into the frame.

[0056] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows: During use, a batch of waste slag is first put into the left top of the conveyor belt 1 through the feed pipe 9. Since the waste slag can be divided into fine waste slag and coarse waste slag according to different sizes, when the waste slag falls onto the conveyor belt 1, most of the fine waste slag will enter the classification trough 4 due to its smaller size, and the coarse waste slag will stay on the top of two or more convex strips 3 due to its larger size to achieve preliminary separation.

[0057] Then start the first drive motor 704, which drives the rotating rod 703 to rotate counterclockwise around its hinge point on the support arm 701; during the rotation of the rotating rod 703, the rotating rod 703 drives the top rod 2 to swing back and forth left and right around the hinge point of the top rod 2 on the support arm 701 through the swing arm 702. Since the crank rocker mechanism has a quick return characteristic, the speed of the top rod 2 when it swings to the right is greater than the speed when it swings to the left, thereby making the average speed of the conveyor belt 1 when moving to the right greater than the average speed when moving to the left.

[0058] During the reciprocating speed-changing swinging of the push rod 2 to the left and right, when the push rod 2 swings from the left extreme position to the right extreme position, the swinging direction of the push rod 2 is the same as the set conveying direction of the waste slag, both to the right, and the first drive cylinder and the second drive cylinder are started at the same time, wherein the output shaft of the first drive cylinder is extended, and the first part is synchronously driven to move away from the second part, so that the length of the push rod 2 is increased, so that the push rod 2 can lift part of the conveyor belt 1, thereby making it more difficult for the coarse waste slag to move synchronously with the conveyor belt 1; the output shaft of the second drive cylinder is extended, and the clamping block 6 is synchronously driven to extend out of the push rod 2 and engage with the clamping slot 5, so that when the push rod 2 swings to the right, it can synchronously drive the conveyor belt 1 to move in the clockwise direction, and the average speed is V1.

[0059] When the push rod 2 moves to the right limit position, the output shaft of the first driving cylinder retracts, and synchronously drives the first part to move in the direction close to the second part, so that the push rod 2 restores its original length; when the push rod 2 swings from the right limit position to the left limit position, the swing direction of the push rod 2 is opposite to the set conveying direction of the waste slag, and the clamping block 6 and the clamping slot 5 are still in the clamping state, so that when the push rod 2 swings to the left, it can drive the conveyor belt 1 to move in the counterclockwise direction, and the average speed is V2; when the push rod 2 swings from the left limit position to the right limit position again, the swing direction of the push rod 2 is the same as the set conveying direction of the waste slag, both to the right, and the output shaft of the first driving cylinder is extended, synchronously driving the first part to move in the direction away from the second part, so that the length of the push rod 2 is increased, so that the push rod 2 can lift part of the conveyor belt 1, and then make it more difficult for the coarse waste slag to move synchronously with the conveyor belt 1, and the clamping block 6 and the clamping slot 5 are still in the clamping state, so that when the push rod 2 swings to the right, it can synchronously drive the conveyor belt 1 to move in the clockwise direction, and the average speed is V1.

[0060] When the push rod 2 moves to the right extreme position, the output shaft of the first driving cylinder retracts, and synchronously drives the first part to move toward the second part, so that the push rod 2 restores its original length; when the push rod 2 swings from the right extreme position to the left extreme position again, the swinging direction of the push rod 2 is opposite to the set conveying direction of the waste slag, and at the same time the output shaft of the second driving cylinder retracts, synchronously drives the clamping block 6 to retract into the inside of the push rod 2, and disengages from the clamping slot 5, and the conveyor belt 1 remains stationary.

[0061] In the above process, since V1>V2, when the push rod 2 drives the conveyor belt 1 to move quickly, the conveyor belt 1 can synchronously drive the fine waste slag to move, and the coarse waste slag is larger in size, thus having a larger mass and inertia, so that when the conveyor belt 1 moves, the coarse waste slag can remain approximately motionless under the action of inertia; when the push rod 2 drives the conveyor belt 1 to move slowly, the conveyor belt 1 synchronously drives the fine waste slag and the coarse waste slag to move; and the fine waste slag moves to the right twice and to the left once, so that the fine waste slag as a whole still moves to the right; the coarse waste slag moves to the left once and does not move to the right, so that the coarse waste slag as a whole moves to the left.

[0062] The above process is repeated, so that the fine waste slag and the coarse waste slag gradually move in opposite directions, so as to separate the waste slag while unloading, thereby improving the waste slag treatment efficiency.

[0063] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
