Description

Technical Field

[0001] This utility model relates to the field of refractory material processing technology, and in particular to a dust handling mechanism for conveying refractory materials. Background Technology

[0002] Dust generation has always been a significant problem to be solved in the processing of refractory materials. Existing technologies, such as Chinese utility model patent application number 201820884475.5, propose a dust removal device for refractory material processing. This device conveys the refractory material through a conveyor roller mechanism and uses a baffle plate that moves up and down under the drive of a cam mechanism to change the pressure of the broom on the surface of the refractory material, thereby cleaning pores at different depths. However, this design may obstruct the smooth movement of the refractory material when it first arrives at the cleaning position if the broom is at its lowest point.

[0003] Another existing technology, Chinese utility model patent application number 202021667674.4, proposes a smoke and dust removal device for refractory material processing. This device has a drive mechanism installed on the support plate to drive the sweeping broom to rotate, thereby improving the cleaning effect. However, it also suffers from the aforementioned problem of obstructed movement of refractory materials.

[0004] To address the shortcomings of the existing technology, this utility model proposes an improved dust handling mechanism for conveying refractory materials, aiming to solve the problem that refractory materials cannot move smoothly due to obstruction by the cleaning mechanism during the conveying process. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a dust handling mechanism for conveying refractory materials to solve the above problems.

[0006] To achieve the above objectives, this utility model provides a dust handling mechanism for conveying refractory materials, including a support, a conveying roller mechanism mounted on the support for conveying refractory materials, a cleaning mechanism movably disposed above the support for cleaning the surface of the refractory materials, and a fan fixedly disposed above the support. The support is fixed with a mounting frame, and the mounting frame is provided with a baffle mechanism for restricting the continued movement of the refractory materials and a lifting mechanism for pushing the refractory materials away from the surface of the conveying roller mechanism.

[0007] The baffle mechanism includes a baffle that is vertically and movably mounted on the mounting frame and a lifting drive device connected between the baffle and the mounting frame. The upper end of the baffle can pass through the roller gap of the conveying roller mechanism and block the movement path of the refractory material.

[0008] The lifting mechanism includes a support plate, a support block, and a support driving mechanism. The support driving mechanism is connected between the mounting frame and the support plate. The lower end of the support block is fixed to the support plate. When the support driving mechanism lifts the support plate upward, it can cause the support block to lift the refractory material upward.

[0009] Preferably, both the lifting drive device and the support drive mechanism are electric telescopic cylinders.

[0010] Preferably, the upper end of the lifting drive device is fixed with a horizontal slide rail, the baffle is slidably connected to the horizontal slide rail, a pressure sensor is connected between the baffle and the end of the horizontal slide rail near the cleaning mechanism, and a spring is connected between the baffle and the other end of the horizontal slide rail.

[0011] Preferably, the bracket is equipped with a photoelectric switch at the end of the lifting mechanism away from the cleaning mechanism.

[0012] Preferably, the mounting bracket is fixed with a PLC controller.

[0013] Preferably, the cleaning mechanism includes a stop plate disposed above the conveyor roller mechanism, a cleaning wheel rotatably mounted below the stop plate, and a cam mechanism disposed on the bracket for driving the stop plate to move up and down.

[0014] Preferably, the abutment is equipped with a rotating mechanism that drives the sweeping wheel to rotate.

[0015] Compared with the prior art, this utility model has the following advantages: In the prior art, there is a problem that the refractory material may be blocked from moving smoothly when it first arrives at the cleaning position because the cleaning mechanism is in a low position. This utility model, by adding a baffle mechanism and a lifting mechanism, and combining the automatic control settings of the PLC controller, realizes the precise positioning of the refractory material during the conveying process and its smooth passage through the cleaning area. At the same time, it reduces the wear of the conveyor rollers and improves the dust handling efficiency and automation level. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1-2 The specific embodiments of this utility model will be described in further detail.

[0021] like Figure 1-2 As shown, this utility model relates to a dust handling mechanism for conveying refractory materials, including a support 1, a conveying roller mechanism 3 mounted on the support 1 for conveying refractory material 2, a cleaning mechanism movably disposed above the support 1 for cleaning the surface of the refractory material 2, and a fan 8 fixedly disposed above the support 1. The cleaning mechanism includes a stop plate 4 disposed above the conveying roller mechanism 3, a cleaning wheel 5 rotatably disposed below the stop plate 4, and a cam mechanism 6 disposed on the support 1 for driving the stop plate 4 to move up and down. A rotating mechanism 7 is mounted on the stop plate 4 to drive the cleaning wheel 5 to rotate. In use, the refractory material 2 is conveyed to the position of the cleaning mechanism through the conveying roller mechanism 3. The cam mechanism 6 drives the cleaning wheel 5 to move up and down to change the pressure on the refractory material 2. In addition, the cleaning wheel 5 is rotated under the drive of the rotating mechanism 7 to clean the surface of the refractory material 2. The above is based on the prior art and will not be described in detail here.

[0022] Based on existing technology, this utility model also incorporates the following innovative designs:

[0023] The bracket 1 is fixed with a mounting frame 11. The mounting frame 11 can be connected to the bracket 1 by bolts or by welding. Only the mounting frame 11 needs to be fixed. The mounting frame 11 is equipped with a baffle mechanism 9 for limiting the movement of the refractory material 2 and a lifting mechanism 10 for pushing the refractory material 2 away from the surface of the conveyor roller mechanism 3. The baffle mechanism 9 is set to temporarily block the moving refractory material 2 and play a positioning role. During the process of blocking the refractory material 2, the lifting mechanism 10 can push the refractory material 2 upward, thereby avoiding friction between the refractory material 2 and the conveyor roller mechanism 3 and reducing the wear of the conveyor roller.

[0024] In this embodiment, the baffle mechanism 9 includes a baffle 91 vertically movably mounted on the mounting frame 11 and a lifting drive device 92 connected between the baffle 91 and the mounting frame 11. The upper end of the baffle 91 can pass through the gap between the rollers of the conveying roller mechanism 3 and block the movement path of the refractory material 2. It can be understood that the conveying roller mechanism 3 is mainly composed of multiple conveying rollers with a certain gap between them. In use, the baffle 91 can be moved upward by the lifting drive device 92 and blocked in the movement path of the refractory material 2, so that when the next piece of refractory material 2 comes into contact with the baffle 91, it will be blocked and unable to move. Then, the baffle 91 is driven downward by the lifting drive device 92. At this time, the position of the refractory material 2 is adjusted, and the cam mechanism 6 drives the sweeping wheel 5 to move up and down in a regular manner, so that when the refractory material 2 reaches the sweeping mechanism, the sweeping wheel 5 can move to a height that allows the refractory material 2 to pass smoothly, thereby ensuring that the refractory material 2 moves smoothly.

[0025] Under normal circumstances, when the conveyor roller transports the refractory material 2, there is static friction between the surface of the conveyor roller and the refractory material 2, resulting in relatively small wear. When the baffle 91 blocks the refractory material 2, there is dynamic friction between the conveyor roller and the refractory material 2, resulting in relatively large wear. In order to reduce wear, when the baffle 91 blocks the refractory material 2, the refractory material 2 can be lifted by the lifting mechanism 10.

[0026] In this embodiment, the lifting mechanism 10 includes a support plate 101, a support block 102, and a support driving mechanism 103. The support driving mechanism 103 is connected between the mounting frame 11 and the support plate 101. The lower end of the support block 102 is fixed to the support plate 101, and there are at least two support blocks 102. The upper end of the support block 102 can move in the gap of the conveying roller, so that when the support driving mechanism 103 lifts the support plate 101 upward, the support block 102 can lift the refractory material 2 upward.

[0027] In this embodiment, both the lifting drive device 92 and the support drive mechanism 103 are electric telescopic cylinders.

[0028] To detect the contact time between the baffle 91 and the refractory material 2, a horizontal slide rail 94 is fixed to the upper end of the lifting drive device 92. The baffle 91 is slidably connected to the horizontal slide rail 94. A pressure sensor 95 is connected between the baffle 91 and the end of the horizontal slide rail 94 near the cleaning mechanism, and a spring 96 is connected between the other end of the baffle 91 and the horizontal slide rail 94. In this way, the baffle 91 can be raised in advance. When the refractory material 2 abuts against the baffle 91, the lower end of the baffle 91 will slide in the horizontal slide rail 94, thereby squeezing the pressure sensor 95. The positioning of the refractory material 2 is determined by the squeezing of the pressure sensor 95. When the refractory material 2 is in position, the support drive mechanism 103 of the lifting mechanism 10 starts to work, so that the support block 102 lifts the refractory material 2.

[0029] In order to detect the arrival of the refractory material 2 and raise the baffle 91 at the appropriate time, the bracket 1 is equipped with a photoelectric switch 12 at the end of the lifting mechanism 10 away from the cleaning mechanism. It can be understood that there are two photoelectric switches 12, which are installed on both sides of the bracket 1 respectively. One is used to emit light signals and the other is used to receive light signals. Only one is shown in the figure. When the refractory material 2 approaches, the light signal will be blocked.

[0030] The mounting bracket 11 is fixed with a PLC controller 13. The PLC controller 13 is electrically connected to the photoelectric switch 12, the lifting drive device 92, the support drive mechanism 103, and the pressure sensor 95. When the refractory material 2 approaches, the photoelectric switch 12 sends a signal to the PLC controller 13. The PLC controller 13 controls the lifting drive device 92 to work, causing the baffle 91 to rise. When the refractory material 2 continues to move and comes into contact with the baffle 91, the baffle 91 presses the pressure sensor 95. The pressure sensor 95 sends a signal to the PLC controller 13. The PLC controller 13 controls the support drive mechanism 103 to work, causing the support block 102 to lift the refractory material 2, allowing the refractory material 2 to enter a waiting time. When the refractory material 2 in the cleaning mechanism area is cleaned, the PLC controller 13 controls the lifting drive device 92 and the support drive mechanism 103 to retract, so that the next piece of refractory material 2 can be sent to the cleaning area.

[0031] In summary, this utility model aims to provide an improved dust handling mechanism for conveying refractory materials, primarily addressing the problem in existing technologies where the cleaning mechanism, when initially positioned low, may obstruct the smooth movement of refractory materials upon arrival at the cleaning area. By adding a baffle mechanism and a lifting mechanism, combined with automated control via a PLC controller, the system ensures precise positioning and smooth passage of refractory materials through the cleaning area during transport, while simultaneously reducing wear on the conveyor rollers and improving dust handling efficiency and automation levels.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
