Description

Technical Field

[0001] The present application relates to the technical field of coking equipment, and in particular to a coke cake dust reduction and forming device in a coking workshop. Background Art

[0002] During coking production, the coal needs to be transported to the carbonization chamber of the coking oven, and then the combustion chambers on both sides of the carbonization chamber are used to transfer heat to the carbonization chamber to perform high-temperature dry distillation on the coal, thereby forming products such as coke and coking gas.

[0003] At present, during coking production, loose coal is usually first rammed into briquettes by briquette forming equipment, and then the briquettes are transported to the carbonization chamber for coking by coking equipment. In this way, a certain amount of inferior coal can be used to replace high-quality coal, making resource utilization more reasonable, and under the same coal blending conditions, the quality of coke can be improved.

[0004] During the above-mentioned coking production process, when the coal cakes are transported to the carbonization chamber, due to the inevitable presence of coal powder on the coal cake forming equipment and the coal cakes, these coal powders will be pushed out of the coal cake forming equipment together with the coal cakes during the transportation process, forming dust between the coal cake forming equipment and the coking oven, and finally scattered around, requiring manual collection and cleaning, causing inconvenience to the coking production, and in windy weather, it will also drift into the air, affecting the environment. Summary of the invention

[0005] In order to improve the convenience of coking production, the present application provides a coke cake dust reduction and forming device in a coking workshop.

[0006] The present application provides a coke cake dust reduction and forming device for a coking workshop, which adopts the following technical solution:

[0007] A coke cake dust reduction and forming device in a coking workshop is used to form coal cakes and transport them to the carbonization chamber of a coke oven, comprising a vehicle body, a tamping box, a tamping assembly, a coal pushing assembly and a door pushing assembly; the tamping box is fixedly arranged on the vehicle body, and a tamping port is provided on the top of the tamping box; the tamping assembly is arranged on the top of the tamping box and is used to tamp the coal in the tamping box; a coal outlet and a coal pushing port are provided on the tamping box, and the coal outlet and the coal pushing port are arranged opposite to each other; the coal pushing assembly is arranged on the vehicle body , and is used to push the coal cakes formed in the tamping box into the carbonization chamber; two box doors are arranged at the opening of the coal outlet, and the two box doors are respectively hinged on both sides of the tamping box; the push door assembly is arranged on the tamping box, and the push door assembly is used to drive the box door to rotate open and close; two isolation plates are arranged at the opening of the coal outlet, and the two isolation plates are respectively fixed on the upper and lower sides of the tamping box, and the two isolation plates and the two box doors can form a channel for coal cakes to pass through.

[0008] By adopting the above technical scheme, during coking production, the operator pours the coal into the tamping box through the tamping port, and then uses the tamping assembly to tamp the coal into coal cakes, and then moves the vehicle body to the carbonization chamber of the coke oven so that the coal outlet faces the carbonization chamber, and then uses the push-door assembly to open the box door. The opened box door and two isolation plates form a channel for the coal cakes to pass through between the tamping box and the carbonization chamber, and then uses the coal pushing assembly to push the formed coal cakes into the carbonization chamber through the channel between the tamping box and the carbonization chamber, and then drives the vehicle body away from the coke oven, closes the coke oven door, and then the coal cakes can be subjected to high-temperature carbonization.

[0009] During the process of transporting coal cakes to the carbonization chamber, even if there is scattered coal powder, it will fall into the channel formed by the box door and the two isolation plates, and will not be scattered around to form dust. There is no need for operators to clean it up, thereby improving the convenience of coking production.

[0010] Optionally, the coal pushing assembly includes a coal pushing block, a coal pushing telescopic rod and a first spring; the coal pushing block is adapted to the coal pushing port and is slidably connected to the tamping box; the coal pushing telescopic rod is horizontally arranged on the vehicle body, and the fixed end of the coal pushing telescopic rod is connected to the vehicle body; the movable end of the coal pushing telescopic rod is fixedly connected to the coal pushing block; the movable end of the coal pushing telescopic rod divides the interior of the fixed end of the coal pushing telescopic rod into a first rod-containing cavity and a first rodless cavity; the first spring is fixedly arranged in the first rod-containing cavity; a driving assembly is arranged on the vehicle body, and the driving assembly is used to drive the coal pushing telescopic rod to extend and retract.

[0011] By adopting the above technical solution, when the rammed coal cakes are pushed into the carbonization chamber, the driving assembly is used to drive the coal pushing telescopic rod to extend, thereby driving the coal blocks to move toward the carbonization chamber and pushing the coal cakes into the carbonization chamber. During this process, the first spring acts as a buffer to reduce the speed of the coal cake movement and prevent the coal cakes from collapsing due to the speed being too fast.

[0012] Optionally, the drive assembly includes an oil tank, an oil outlet pipe and a first connecting pipe; the oil tank is fixedly mounted on the vehicle body, and oil is preset in the oil tank; the oil outlet pipe is connected to the interior of the oil tank, and an oil pump is installed on the oil outlet pipe; both ends of the first connecting pipe are respectively connected to the oil outlet pipe and the first rodless cavity.

[0013] By adopting the above technical solution, the oil in the oil tank is transported to the first rodless cavity through the oil outlet pipe and the first connecting pipe by the oil pump, so that the movable end of the coal pushing telescopic rod overcomes the first spring to extend.

[0014] Optionally, the push door assembly is provided with two groups, the push door assembly corresponds to the box door one by one, the push door assembly includes a push door telescopic rod, a hinge block, a transmission rod and a second spring; the fixed end of the push door telescopic rod is fixedly connected to the tamping box; the hinge block is hinged on the tamping box; the transmission rod is passed through the hinge block, and its two ends are respectively hinged to the movable end of the push door telescopic rod and the box door; the movable end of the push door telescopic rod divides the interior of the fixed end of the push door telescopic rod into a second rod-containing cavity and a second rodless cavity; the second spring is fixedly disposed in the second rodless cavity, and the elastic force of the second spring is less than the elastic force of the first spring; the driving assembly also includes a second connecting tube, two of which are provided and correspond to the push door telescopic rod one by one, and the two ends of the second connecting tube are respectively connected to the first rodless cavity and the second rod-containing cavity.

[0015] By adopting the above technical solution, the tamping box, the hinge block and the transmission rod form a lever structure. When in use, the oil in the oil tank is transported to the second rod cavity through the oil outlet pipe, the first connecting pipe, the first rodless cavity and the second connecting pipe by the oil pump, so that the door push telescopic rod overcomes the second spring to shrink, driving the hinge block and the transmission rod to move, thereby driving the box door to rotate and open. Since the elastic force of the second spring is less than the elastic force of the first spring, the oil flowing out of the oil tank will first cause the coal pushing telescopic rod to shrink, and after the box door is rotated and opened, it will drive the coal pushing telescopic rod to extend, pushing the coal cake into the carbonization chamber.

[0016] Optionally, a limiting groove is provided on the isolation plate located at the top of the tamping box; a limiting assembly is arranged on the vehicle body, and the limiting assembly includes a limiting telescopic rod, a third spring and a first limiting block; the fixed end of the limiting telescopic rod is fixedly arranged on the isolation plate located at the top of the tamping box, and the movable end of the limiting telescopic rod divides the interior of the fixed end of the limiting telescopic rod into a third rod cavity and a third rodless cavity; the third spring is fixedly arranged in the third rodless cavity; the first limiting block is adapted to the limiting groove, the first limiting block is slidably arranged in the limiting groove, and is fixedly connected to the movable end of the limiting telescopic rod; the driving assembly also includes a third connecting pipe, one end of the third connecting pipe is connected to the third rod cavity, and the other end is connected to both the oil outlet pipe and the first connecting pipe; an overflow valve is arranged on the first connecting pipe, and the elastic force of the third spring is less than the starting pressure of the overflow valve.

[0017] By adopting the above technical solution, when tamping the coal, the box door is in a closed state, and under the action of the third spring, the limiting telescopic rod is in an extended state, and the first limiting block abuts against the side of the box door away from the tamping box, thereby limiting the box door and ensuring that the box door is always in a closed state during the tamping process, thereby preventing the coal from leaking from the gap between the box doors due to the tamping hammer hitting the coal in the tamping box.

[0018] After the coal cakes are tamped, before opening the box door, the operator first needs to use the oil pump to transport the oil in the oil tank through the oil outlet pipe and the third connecting pipe to the third rod chamber, so that the limit telescopic rod contracts, thereby driving the first limit block to move upward and away from the box door. At this time, the box door can be opened, and the overflow valve is used to ensure that the oil flowing out of the oil tank will first enter the third rod chamber, thereby moving the first limit block away from the box door.

[0019] Optionally, the limiting assembly further includes a second limiting block, which is fixedly disposed on the vehicle body and is used to limit the pushing coal block.

[0020] By adopting the above technical solution, when tamping the coal, the second limit block is used to limit the coal pusher to ensure that one end of the coal pusher is always located in the tamping box, and the coal pushing port is always in a closed state during the tamping process, thereby preventing the coal from leaking from the coal pushing port due to the tamping hammer hitting the coal in the tamping box.

[0021] Optionally, the drive assembly further includes a return pipe, both ends of which are respectively connected to the third connecting pipe and the oil tank; and an electric valve is installed on the return pipe.

[0022] By adopting the above technical solution, after pushing the coal cake into the carbonization chamber, the operator drives the vehicle body away from the coke oven, then turns off the oil pump and starts the electric valve. At this time, because the elastic force of the first spring is the largest and greater than the starting pressure of the overflow valve, under the action of the first spring, the coal-pushing telescopic rod first shrinks and resets, and the oil in the first rodless chamber flows back to the oil tank through the first connecting pipe, the third connecting pipe and the return pipe. Then, because the elastic force of the second spring is greater than the elastic force of the third spring and greater than the starting pressure of the overflow valve, under the action of the elastic force of the second spring, the door-pushing telescopic rod shrinks and resets later than the coal-pushing telescopic rod, and the oil in the second rod chamber also flows back to the oil tank, and the door-pushing telescopic rod drives the box door to close through the transmission rod and the hinge block.

[0023] When the box door is closing, the bottom of the box door will push the coal scattered on the isolation plate at the bottom of the tamping box back into the tamping box, thereby reducing the workload of subsequent operators in recovering the loose coal on the isolation plate and improving the convenience of coking production.

[0024] After the box door is closed, the limiting telescopic rod extends under the elastic force of the third spring, thereby driving the first limiting block to move downward, and the first limiting block abuts against the side of the box door away from the tamping box again, thereby completing the reset and continuing to tamp the subsequent coal cakes.

[0025] Optionally, the tamping assembly includes a tamping hammer and a hydraulic cylinder; the tamping hammer is adapted to the tamping port, and the tamping hammer is slidably arranged with the tamping box; the hydraulic cylinder is located at the top of the tamping box, the fixed end of the hydraulic cylinder is fixedly connected to the vehicle body, and the tamping hammer is fixedly connected to the movable end of the hydraulic cylinder.

[0026] By adopting the above technical solution, when tamping the coal, the hydraulic cylinder is used to drive the tamping hammer to move up and down repeatedly, so that the coal is tamped into coal cakes.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] During coking production, the operator pours the coal into the tamping box through the tamping port, and then uses the tamping assembly to tamp the coal into briquettes, and then moves the vehicle body to the carbonization chamber of the coke oven so that the coal outlet faces the carbonization chamber, and then uses the push door assembly to open the box door, and the opened box door and two isolation plates form a channel for the briquettes to pass through between the tamping box and the carbonization chamber, and then uses the coal pushing assembly to push the formed briquettes into the carbonization chamber through the channel between the tamping box and the carbonization chamber, and then drives the vehicle body away from the coke oven, closes the coke oven door, and then the briquettes can be subjected to high-temperature carbonization. In the process of transporting the briquettes to the carbonization chamber, even if there is scattered coal powder, it will fall into the channel formed by the box door and the two isolation plates, and will not be scattered around to form dust, and there is no need for the operator to clean it up, thereby improving the convenience of coking production.

[0058] Reference Figure 6 and Figure 7 One end of the third connecting pipe 75 is connected to the third rod chamber 811, and the other end is connected to both the oil outlet pipe 72 and the first connecting pipe 73. A relief valve 731 is fixedly installed on the first connecting pipe 73, and the starting pressure of the relief valve 731 is less than the elastic force of the first spring 53 and the second spring 64, but greater than the elastic force of the third spring 82. Both ends of the return pipe 76 are connected to the third connecting pipe 75 and the oil tank 71 respectively. An electric valve 761 is installed on the return pipe 76.

[0059] The implementation principle of a coke cake dust reduction and forming device in a coking workshop according to the embodiment of the present application is as follows:

[0060] In the initial state, due to the action of the first spring 53, the coal pushing telescopic rod 52 is in a contracted state, and the side of the coal pushing block 51 away from the tamping box 3 abuts against the second stop block 84. Under the action of the second spring 64, the door pushing telescopic rod 61 is in an extended state, so that the box door 34 is in a closed state. Under the action of the third spring 82, the stop telescopic rod 81 is in an extended state, so that the first stop block 83 abuts against the side of the box door 34 away from the tamping box 3. Thus, a coal cake forming cavity is formed in the tamping box 3.

[0061] During coking production, the operator uses the hydraulic cylinder 42 to drive the tamping hammer 41 to move away from the tamping box 3, then pours the coal into the tamping box 3 through the tamping port 31, and then uses the hydraulic cylinder 42 to drive the tamping hammer 41 to move up and down repeatedly, thereby tamping the coal into coal cakes.

[0062] After the coal cakes are tamped, the operator moves the vehicle body 2 to the carbonization chamber 11 of the coke oven 1 so that the coal outlet 32 ​​faces the carbonization chamber 11, and then the operator checks the electric valve 761 to ensure that the electric valve 761 is in a closed state, and then starts the oil pump 721 to allow the oil in the oil tank 71 to flow out through the oil outlet pipe 72. Since the starting pressure of the overflow valve 731 is greater than the elastic force of the third spring 82, the oil flowing out of the oil outlet pipe 72 first passes through the third connecting pipe 75 and enters the third rod cavity 811, thereby overcoming the pressure of the third spring 82 to shrink the limiting telescopic rod 81, thereby driving the first limiting block 83 to move upward until it is away from the box door 34.

[0063] When the third connecting pipe 75 shrinks to the point where the third spring 82 is at its minimum length, the oil subsequently flowing out of the oil outlet pipe 72 will pass through the first connecting pipe 73, through the overflow valve 731, and into the first rodless chamber 522. Since the elastic force of the second spring 64 is less than the elastic force of the first spring 53, the oil in the first rodless chamber 522 will first pass through the second connecting pipe 74 and enter the second rod chamber 611, so that the door-pushing telescopic rod 61 overcomes the elastic force of the second spring 64 and shrinks. The movable end of the door-pushing telescopic rod 61 drives the transmission rod 63 and the hinge block 62 to move. Since the transmission rod 63, the hinge block 62 and the tamping box 3 form a lever structure, the movement of the transmission rod 63 and the hinge block 62 will drive the box door 34 to rotate and open. When the box door 34 is fully opened, the two box doors 34 and the two isolation plates 35 form a channel connecting the tamping box 3 and the carbonization chamber 11.

[0064] After the box door 34 is fully opened, as the oil entering the first rodless chamber 522 gradually increases, the coal pushing telescopic rod 52 overcomes the elastic force of the first spring 53 and extends, thereby driving the coal pushing block 51 to move toward the carbonization chamber 11, and the coal cakes in the tamping box 3 enter the carbonization chamber 11 through the channel formed by the two box doors 34 and the two isolation plates 35. Then the operator drives the vehicle body 2 away from the coke oven 1 and closes the door of the coke oven 1, and the coal cakes can be subjected to high-temperature dry distillation. In this process, even if there is scattered coal in the tamping box 3, it will fall into the channel formed by the two box doors 34 and the two isolation plates 35, and will not be scattered around to form dust.

[0065] After the vehicle body 2 is away from the coke oven 1, the operator turns off the oil pump 721 and starts the electric valve 761. At this time, since the elastic force of the first spring 53 is the largest and greater than the starting pressure of the relief valve 731, under the action of the first spring 53, the coal pushing telescopic rod 52 contracts until the coal pushing block 51 abuts against the second limit block 84, and the oil in the first rodless chamber 522 flows back to the oil tank 71 through the first connecting pipe 73, the third connecting pipe 75 and the return pipe 76.

[0066] When the coal pushing port 33 abuts against the second limit block 84, since the elastic force of the second spring 64 is greater than the elastic force of the third spring 82 and greater than the starting pressure of the overflow valve 731, under the elastic force of the second spring 64, the push-door telescopic rod 61 contracts, and the oil in the second rod chamber 611 flows back to the oil tank 71 through the second connecting pipe 74, the first rodless chamber 522, the first connecting pipe 73, the third connecting pipe 75 and the return pipe 76. The push-door telescopic rod 61 drives the box door 34 to close through the transmission rod 63 and the hinge block 62. During the closing process of the box door 34, the bottom of the box door 34 will push the coal scattered on the isolation plate 35 at the bottom of the tamping box 3 back into the tamping box 3.

[0067] After the box door 34 is closed, the limiting telescopic rod 81 extends under the elastic force of the third spring 82, thereby driving the first limiting block 83 to move downward, and the first limiting block 83 abuts against the side of the box door 34 away from the tamping box 3 again, thereby completing the reset and continuing the subsequent tamping of coal cakes.

[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
