Description

Technical Field

[0001] This invention belongs to the field of pusher kiln sintering technology, specifically relating to a pusher control method and a pusher kiln system. Background Technology

[0002] The general working process of a pusher kiln is as follows: the operator fills the pusher plates inside the furnace in advance, heats up and ventilates, and adjusts the equipment to the ready-to-process state. The operator places the workpiece on the pusher plate outside the furnace, and the pusher plate is pushed into the furnace by the propulsion system. The pusher plate carries the workpiece through the furnace to complete the sintering process. Pusher kilns are characterized by continuous sintering and high output.

[0003] In traditional methods, the main propulsion motor of the pusher kiln pushes the pusher plate forward a fixed distance each time. This approach has a problem: the pusher plate, under long-term load and compression at high temperatures, will undergo deformation. This deformation accumulates gradually and is difficult to predict and manage in advance. After a period of time, the sintering time of the workpiece carried by the pusher plate in the furnace will differ from the expected time, thus affecting the sintering quality. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a pusher control method and pusher kiln system that are simple to operate, highly compatible and precise in control, in order to overcome the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A pusher control method includes the following steps:

[0007] Step S1: The main pusher pushes the pusher plate to move in the furnace body at a speed of v1 until the main pusher contacts the speed change switch. The movement time is t1.

[0008] Step S2: The main pusher pushes the push plate to move in the furnace body at a speed of v2, so that the push plate at the front end of the furnace body contacts the connecting rod and continues to move forward until the connecting rod contacts the stop switch outside the furnace body, at which point the main pusher stops moving.

[0009] Step S3: The main drive unit retracts at a speed of v3 until it contacts the retracted position switch, and the movement time is t3.

[0010] Step S4: The second inlet drive pushes a new pusher plate into the main track of the furnace body and returns, with a movement time of t4;

[0011] Step S5: While the main push drive is retracting and the second inlet drive is advancing, the first outlet drive pushes the push plate at the front end of the furnace body out of the furnace body and returns, and the drive cylinder pushes the connecting rod to reset in the furnace body.

[0012] Step S6: Complete one push plate movement and enter the next cycle.

[0013] As a further improvement of the present invention, at the beginning of the installation and commissioning of the pusher kiln, the furnace body is filled with pusher plates. The installation position of the speed change switch is adjusted so that when the main pusher drive unit contacts the first pusher plate at the input end of the furnace body, the pusher plate at the front end of the output end of the furnace body pushes the connecting rod to contact the position switch outside the furnace body. At this time, the total number of pusher plates in the furnace body is n. Let the initial width of a single pusher plate be d, and the total distance that a single pusher plate moves at a speed v2 in the furnace body be L. Then L = n × d.

[0014] As a further improvement of the present invention, the speed v1 > speed v2, and the speed v3 > speed v2.

[0015] As a further improvement of the present invention, when the push plate is squeezed and narrowed, resulting in a reduction in the stroke of the main push drive component, a new push plate is added to the push plate cycle. At this time, the total number of push plates in the furnace body is k, then k≥n, and the total distance L of a single push plate from entering the furnace body to being pushed out of the furnace body is k. During this process, the number of push cycles in the furnace body is k.

[0016] As a further improvement of the present invention, the total movement time of a single pusher plate in the furnace body is t, then t=k(t1+t3+t4)+(n×d / v2).

[0017] As a further improvement of the present invention, the total time k(t1+t3+t4) for the pusher to enter and exit the furnace body is less than the total time (n×d / v2) for the pusher to move forward in the furnace body, and k(t1+t3+t4) is a fixed value.

[0018] As a general technical concept, the present invention also provides a pusher kiln system for implementing the above-mentioned control method, comprising: a main pusher drive, a furnace body, an outlet drive, a drive cylinder, a return drive, a conveyor roller, an inlet drive, and a connecting rod; the output end of the conveyor roller is connected to the input end of the furnace body, and the output end of the furnace body is connected to the input end of the conveyor roller to form a circulation loop; an inlet drive and a main pusher drive are provided at the input end of the furnace body, the inlet drive being used to push the pusher plate loaded with the workpiece on the conveyor roller to the inlet of the furnace body, and the main pusher drive being used to push the pusher plate at the inlet to the inlet. A pusher plate is pushed into the furnace body to enable the workpiece to undergo sintering within the furnace. At the output end of the furnace body, there is an outlet drive, a drive cylinder, a return drive, and a connecting rod. The connecting rod passes through the inside and outside of the furnace body and is connected to the output end of the drive cylinder. The drive cylinder assists in resetting the connecting rod within the furnace body. During the process, the pusher plate pushes the connecting rod to move. When one end of the connecting rod contacts the stop switch outside the furnace body, the main pusher stops, and the outlet drive pushes the sintered workpiece and pusher plate out of the furnace body. The return drive is used to push the unloaded pusher plate onto the conveyor rollers.

[0019] As a further improvement of the present invention, at the input end of the furnace body, along the pushing direction of the pusher plate, a retraction switch, a speed change switch, and a limit switch are sequentially provided to match the main pusher drive component; when the main pusher drive component contacts the retraction switch, the inlet drive component pushes the pusher plate loaded with the workpiece on the conveyor roller to the inlet of the furnace body; when the main pusher drive component pushes the pusher plate forward and contacts the speed change switch, the main pusher drive component switches speeds; when the main pusher drive component contacts the limit switch, the connecting rod contacts the positioning switch outside the furnace body, and the main pusher drive component stops operating.

[0020] As a further improvement of the present invention, the outlet drive includes: a first outlet drive, a second outlet drive, and an outlet transverse push drive, wherein the movement directions of the first outlet drive and the outlet transverse push drive are perpendicular to each other, and the movement directions of the first outlet drive and the second outlet drive are parallel to each other; the inlet drive includes: an inlet transverse push drive, a first inlet drive, and a second inlet drive, wherein the movement direction of the inlet transverse push drive and the first inlet drive are perpendicular to each other, and the movement directions of the first inlet drive and the second inlet drive are parallel to each other.

[0021] As a further improvement of the present invention, at the output end of the furnace body, along the pushing direction of the pusher plate, a retraction switch and an advance switch matching the first outlet drive are provided; at the input end of the furnace body, along the pushing direction of the pusher plate, a retraction switch and an advance switch matching the second inlet drive are provided.

[0022] Compared with the prior art, the advantages of the present invention are as follows:

[0023] 1. The pusher control method of the present invention involves the main pusher first pushing the pusher plate within the furnace body at a speed of v1 until it contacts the speed change switch; then, the main pusher pushes the pusher plate within the furnace body at a speed of v2, causing the pusher plate at the foremost point within the furnace body to contact the connecting rod and continue moving forward until the connecting rod contacts the stop switch outside the furnace body, at which point the main pusher stops; finally, the main pusher retracts at a speed of v3 until it contacts the retraction stop switch, and the second inlet drive pushes a new pusher plate into the main track of the furnace body and returns. Simultaneously with the retraction of the main pusher and the advancement of the second inlet drive, the first outlet drive pushes the pusher plate at the foremost point within the furnace body out of the furnace body and returns, while the drive cylinder pushes the connecting rod to reset within the furnace body. This completes one pusher movement. The entire control process is logically clear, requiring only adjustment of the advancement speed of the main pusher to achieve precise control of the pusher time, ensuring the stability of the workpiece sintering quality.

[0024] 2. The pusher kiln system of the present invention forms a loop by connecting the conveyor rollers to the furnace body end to end, realizing continuous sintering of workpieces loaded on pusher plates. An inlet drive and a main pusher drive are provided at the input end of the furnace body. The inlet drive pushes the pusher plate loaded with workpieces on the conveyor rollers to the furnace inlet, and the main pusher drive pushes the pusher plate at the inlet into the furnace body, realizing the sintering process of the workpieces inside the furnace body. An outlet drive, a drive cylinder, a return drive, and a connecting rod are provided at the output end of the furnace body. The connecting rod passes through the inside and outside of the furnace body and is connected to the output end of the drive cylinder. During the process, the pusher plate pushes the connecting rod to move. When one end of the connecting rod contacts the stop switch outside the furnace body, the main pusher drive stops, the outlet drive pushes the sintered workpiece and pusher plate out of the furnace body, the drive cylinder assists the connecting rod to reset inside the furnace body, and the return drive pushes the empty pusher plate onto the conveyor rollers for the next cycle. The entire pusher kiln system has a compact structure, is easy to operate, and achieves precise control of the pusher plate sintering time, which is beneficial to improving the sintering quality of the workpieces.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific preferred embodiments, but this does not limit the scope of protection of the present invention.

[0030] Example 1

[0031] like Figure 1 and Figure 2As shown, the pusher kiln system of the present invention includes: a main pusher drive 1, a furnace body 2, an outlet drive 1, a drive cylinder 4, a return drive 6, a conveyor roller 8, an inlet drive 1, and a connecting rod 13. The output end of the conveyor roller 8 is connected to the input end of the furnace body 2, and the output end of the furnace body 2 is connected to the input end of the conveyor roller 8 to form a circulation loop. An inlet drive 1 and a main pusher drive 1 are provided at the input end of the furnace body 2. The inlet drive 1 is used to push the pusher plate 12 loaded with workpieces on the conveyor roller 8 to the inlet of the furnace body 2, and the main pusher drive 1 is used to push the pusher plate 12 at the inlet into the furnace body 2 to realize the sintering process of the workpieces within the furnace body 2. An outlet drive 1, a drive cylinder 4, a return drive 6, and a connecting rod 13 are provided at the output end of the furnace body 2. The connecting rod 13 penetrates the inside and outside of the furnace body 2 and is connected to the output end of the drive cylinder 4. The drive cylinder 4 is used to assist the connecting rod 13 in resetting within the furnace body 2. During the process, the pusher plate 12 pushes the connecting rod 13 to move. When one end of the connecting rod 13 contacts the position switch outside the furnace body 2, the main pusher drive 1 stops moving, and the outlet drive pushes the sintered workpiece and the pusher plate 12 out of the furnace body 2. The return drive 6 is used to push the unloaded pusher plate 12 onto the conveyor roller 8 for the next pusher cycle.

[0032] like Figure 2 As shown, in this embodiment, at the input end of the furnace body 2, along the advancing direction of the pusher plate 12, a retraction switch, a speed change switch, and a limit switch, matching the main pusher drive 1, are sequentially provided. When the main pusher drive 1 contacts the retraction switch, the inlet drive pushes the pusher plate 12 loaded with the workpiece on the conveyor roller 8 to the inlet of the furnace body 2. When the main pusher drive 1 pushes the pusher plate 12 forward and contacts the speed change switch, the main pusher drive 1 switches its speed. When the main pusher drive 1 contacts the limit switch, the connecting rod 13 contacts the positioning switch outside the furnace body 2, and the main pusher drive 1 stops operating.

[0033] like Figure 1 As shown, in this embodiment, the outlet drive includes a first outlet drive 3, a second outlet drive 5, and an outlet horizontal push drive 7. The movement directions of the first outlet drive 3 and the outlet horizontal push drive 7 are perpendicular to each other, and the movement directions of the first outlet drive 3 and the second outlet drive 5 are parallel to each other. An inner door and an outer door are arranged sequentially from the inside to the outside at the output end of the furnace body 2. The outlet horizontal push drive 7 is located between the inner door and the outer door. After the inner door is opened, the first outlet drive 3 pushes the push plate 12 inside the furnace body 2 out of the inner door. When the outer door is opened, the outlet horizontal push drive 7 pushes the push plate 12 out of the outer door. The second outlet drive 5 pushes the push plate 12 onto the conveyor roller 8.

[0034] The inlet drive unit includes an inlet horizontal push drive unit 9, a first inlet drive unit 10, and a second inlet drive unit 11. The movement directions of the inlet horizontal push drive unit 9 and the first inlet drive unit 10 are perpendicular to each other, and the movement directions of the first inlet drive unit 10 and the second inlet drive unit 11 are parallel to each other. An outer door and an inner door are arranged sequentially from the outside to the inside at the input end of the furnace body 2. The inlet horizontal push drive unit 9 is located between the inner door and the outer door. After the outer door is opened, the first inlet drive unit 10 pushes the push plate 12 on the conveyor roller 8 into the outer door. When the inner door is opened, the inlet horizontal push drive unit 9 pushes the push plate 12 into the inner door. The second inlet drive unit 11 pushes the push plate 12 to the inlet of the furnace body 2.

[0035] like Figure 1 As shown, in this embodiment, at the output end of the furnace body 2, along the pushing direction of the pusher plate 12, a retraction switch and an advance switch matching the first outlet drive 3 are provided to control the forward and backward displacement of the first outlet drive 3. At the input end of the furnace body 2, along the pushing direction of the pusher plate 12, a retraction switch and an advance switch matching the second inlet drive 11 are provided to control the forward and backward displacement of the second inlet drive 11.

[0036] In this embodiment, the main push drive 1, the first outlet drive 3, the second outlet drive 5, the outlet transverse push drive 7, the inlet transverse push drive 9, the first inlet drive 10, and the second inlet drive 11 can all be driven by servo motors. It is understood that in other embodiments, cylinders or electric push rods can also be used as drive components.

[0037] Example 2

[0038] like Figure 3 As shown, the pusher control method of the present invention is implemented based on the pusher kiln system in Embodiment 1, and includes the following steps:

[0039] Step S1: The main pusher 1 pushes the pusher plate 12 to move inside the furnace body 2 at a speed v1 until the main pusher 1 contacts the speed change switch. The movement time is t1.

[0040] Step S2: The main push drive 1 pushes the push plate 12 to move inside the furnace body 2 at a speed of v2, so that the push plate 12 at the front end inside the furnace body 2 contacts the connecting rod 13 and continues to move forward until the connecting rod 13 contacts the position switch outside the furnace body 2, and the main push drive 1 stops moving.

[0041] Step S3: The main drive unit 1 retracts at a speed of v3 until it contacts the retraction switch, and the movement time is t3.

[0042] Step S4: The second inlet drive component 11 pushes the new pusher plate 12 into the main track of the furnace body 2 and returns, with a movement time of t4;

[0043] Step S5: While the main push drive 1 is retracting and the second inlet drive 11 is advancing, the first outlet drive 3 pushes the push plate 12 at the front end of the furnace body 2 out of the furnace body and returns, and the drive cylinder 4 pushes the connecting rod 13 to reset in the furnace body 2.

[0044] Step S6: Complete one push plate movement and enter the next cycle.

[0045] Furthermore, at the beginning of the installation and commissioning of the pusher kiln, the furnace body 2 is filled with pusher plates 12. The installation position of the speed change switch is adjusted so that when the main pusher drive component 1 contacts the first pusher plate 12 at the input end of the furnace body 2, the pusher plate 12 at the front end of the output end of the furnace body 2 pushes the connecting rod 13 to contact the position switch outside the furnace body 2. At this time, the total number of pusher plates 12 in the furnace body 2 is n. Let the initial width of a single pusher plate 12 be d, and the total distance that a single pusher plate 12 moves at a speed v2 in the furnace body 2 be L. Then L = n × d.

[0046] In this embodiment, speed v1 is much greater than speed v2, and speed v3 is much greater than speed v2. That is, the pusher plate is pushed into the furnace body 2 at a slower speed. The starting position of the slow movement of the pusher plate 12 is the position where the main pusher drive 1 drives the pusher plate 12 to contact the speed change switch. The ending position of the slow movement of the pusher plate 12 is the position where the pusher plate 12 pushes the connecting rod 13 to contact the position switch outside the furnace body 2.

[0047] In this embodiment, as the furnace operates for a period of time, the push plate 12 is squeezed and narrowed. After accumulating to a certain extent, the stroke of the main push drive 1 is insufficient. At this time, a new push plate 12 needs to be added to the push plate cycle. The total number of push plates inside the furnace body 2 is k, then k≥n. The total movement distance of a single push plate 12 from entering the furnace body 2 to being pushed out of the furnace body 2 is L. During this process, the number of push cycles inside the furnace body 2 is k.

[0048] In this embodiment, the total movement time of a single pusher plate 12 within the furnace body 2 is t, then t = k(t1 + t3 + t4) + (n × d / v2). Specifically, the retraction time t3 of the main pusher drive 1 + the movement time t4 of the second inlet drive 11 > the movement time of the first outlet drive 3 + the extension / retraction time of the drive cylinder; therefore, the total time of a single pusher plate 12 within the furnace body 2 is:

[0049] t = k(t1 + t3 + t4) + (n × d / v2).

[0050] In this embodiment, since speeds v1 and v3 are much greater than speed n2, the total time k(t1+t3+t4) for the pusher plate 12 to enter and exit the furnace body 2 is much less than the total time (n×d / v2) for the pusher plate 12 to move forward in the furnace body 2. Furthermore, speeds v1 and v3 can be set to constant values, and k(t1+t3+t4) is also a fixed value. Therefore, by setting different movement speeds v2 for different process products, the sintering requirements of different workpieces can be met.

[0051] In this embodiment, since the distance between the speed switch on the outside of the input end of the furnace body 2 and the position switch on the outside of the output end of the furnace body 2 is fixed, and the recommended speed v2 of the pusher plate 12 in the furnace body 2 is also controllable, the pusher plate 12 is deformed due to long-term compression during the process. The running time of the pusher plate 12 in the furnace body 2 can also be calculated by the relationship between the running distance and the pushing speed, so as to achieve precise control of the sintering time of the workpiece and ensure the consistency of the sintering quality of the workpiece.

[0052] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the spirit and technical essence of the invention. Therefore, any simple modifications, equivalent substitutions, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, shall still fall within the scope of protection of the present invention.
