Description

Technical Field

[0001] The utility model belongs to the technical field of pellet burning, and in particular relates to a lower roller screen belt monitoring device for pellet burning. Background Art

[0002] Pelletizing is a method of artificial block raw materials. It is a process of converting powdered materials into physical properties and chemical composition that can meet the requirements of the next step of processing. During the pelletizing process, the material not only undergoes physical properties such as density, porosity, shape, size and mechanical strength due to rolling into balls and dense particles, but more importantly, chemical and physicochemical properties such as chemical composition, reducibility, expansion, high temperature reduction softening, low temperature reduction softening, melting ratio, etc., which improves the metallurgical properties of the material.

[0003] After the pelletizing process is completed but before drying, the pellets may be of different sizes, some may not reach the predetermined size or have irregular shapes. At this time, the produced pellets need to be screened. The screening process will be used to separate unqualified small balls or fragments to ensure that the pellets entering the drying stage have consistent size and shape. Unqualified pellets are returned to the pelletizing batching bin through the belt for re-pelleting.

[0004] In the above process, when the belt transports unqualified pellets, the pellets contain more water, so the pellets will adhere to the belt. When there are too many pellets adhering to the belt, the weight of the belt increases, causing the belt running speed to decrease, and even causing the belt motor to overload and burn. Therefore, it is necessary to manufacture a device that can monitor the operation of the belt. Utility Model Content

[0005] In order to solve the problem that the existing technology cannot monitor the belt, resulting in a decrease in the belt running speed, and even causing the belt motor to be overloaded and burned, the utility model provides a pellet ore burning lower roller screen belt monitoring device, which can scrape off the pellets adhering to the belt to prevent the pellets from adhering to the belt all the time; at the same time, through the set laser speed sensor, the linear speed of the belt operation can be monitored in real time. When the linear speed of the belt operation is lower than the normal speed for a long time, an alarm can be issued in time to remind the staff to carry out maintenance in time.

[0011] A further improvement of the above technical solution of the utility model is that: a clamping groove for placing a scraper is opened on the top of the sliding plate along its length direction, and the scraper is fixedly clamped in the clamping groove by a clamping mechanism.

[0012] A further improvement of the technical solution of the utility model is that the clamping mechanism includes two clamping plates vertically arranged in the clamping groove, and a bidirectional screw penetrating the two clamping plates is rotatably arranged in the clamping groove; wherein the two clamping plates are respectively located on both sides of the bidirectional screw.

[0013] A further improvement of the above technical solution of the utility model is that one end of each bidirectional screw rod extends outside the sliding plate and is fixedly sleeved with a screw rod head.

[0014] A further improvement of the above technical solution of the utility model is that the laser speed sensor is connected to a control terminal signal for controlling the belt provided with the Zigbee module through the Zigbee module provided on the sliding plate.

[0031] In the present invention, the sliding plate 2 can be further referred to when it is specifically set. Figure 1 and Figure 2 ,according to Figure 1 and Figure 2 It can be seen that a vertical slide groove 11 is provided at the lower part of the opposite side of the two columns 1, and a slider 12 extending outside the slide groove 11 is slidably connected in each slide groove 11, and one end of the slider 12 outside the slide groove 11 is fixedly connected to the lower part of the side wall of the corresponding sliding plate 2; continue to refer to Figure 1 and Figure 2 A vertical spring 13 is provided in each slide groove 11 , the bottom end of the spring 13 is fixedly connected to the bottom of the corresponding slide groove 11 , and the top end of the spring 13 is fixedly connected to the bottom of the slider 12 in the corresponding slide groove 11 .

[0032] The scraper 3 in the utility model can be referred to in the specific setting Figure 1-Figure 4 ,according to Figure 1-Figure 4 It can be seen that the scraper 3 in the utility model is composed of multiple scraper blocks 31, and a cut corner 32 is provided on the top of each scraper block 31 on the side opposite to the belt moving direction, that is, if the return section of the belt moves to the left, the cut corner 32 is set on the right side of the top of the scraper block 31, and if the return section of the belt moves to the right, the cut corner 32 is set on the left side of the top of the scraper block 31. At the same time, the cut corner 32 in the utility model can be set as an arc-shaped cut corner 32.

[0033] The scraper 3 in the utility model can be referred to in the specific setting Figure 3 and Figure 4 ,according to Figure 3 and Figure 4 It can be seen that a clamping groove 21 is provided at the top of the sliding plate 2 along its length direction, and the clamping groove 21 fixes and clamps the scraper 3 in the clamping groove 21 through a clamping mechanism 22; Figure 3 and Figure 4It can be seen that the clamping mechanism 22 of the present invention includes two clamping plates 221 vertically arranged in the clamping groove 21, and the clamping groove 21 is rotatably connected to a plurality of bidirectional screws 222 perpendicular to the clamping plates 221, each bidirectional screw 222 penetrates the two clamping plates 221, and the two clamping plates 221 are respectively located on both sides of the bidirectional screw 222 and are threadedly connected to the bidirectional screw 222; continue to refer to Figure 3 and Figure 4 One end of each bidirectional screw 222 extends to the outside of the sliding plate 2 and is fixedly sleeved with a screw head 223 .

[0034] Continue to refer Figure 1 and Figure 2 It can be seen that in the utility model, the top of the sliding plate 2 is located on the side of the scraper block 31 away from the cutting angle 32 and is fixedly connected with an upward laser speed sensor 4. The laser speed sensor 4 is used to monitor the linear speed of the belt return section during operation. At the same time, the laser speed sensor 4 is connected to a control terminal (not shown in the figure) for controlling the belt through a zigbee module (not shown in the figure) located on the sliding plate 2 through a wireless signal. The above-mentioned zigbee module can adopt the E180-Z6907A model produced by Chengdu Yibite Electronic Technology Co., Ltd., which can provide itself with power by installing a battery.

[0035] The control terminal in the utility model is also provided with a display screen for displaying the monitoring information of the laser speed measuring sensor 4 and an alarm for issuing an alarm, and the alarm can adopt an audible and visual alarm commonly used in the prior art.

[0036] The working principle of the belt monitoring device for the lower roller screen of the pellet ore burning of this embodiment is as follows: before using the utility model, first move the utility model, move the utility model to the bottom of the return section of the belt, and the slider 12 moves upward in the slide 11 under the action of the spring 13 until the top of the scraper 3 fits with the return section of the belt. When the belt is running, the pellets adhering to the belt will be scraped off by the scraper 3, thereby preventing the pellets from adhering to the belt for a long time, causing the belt running speed to be reduced, and even causing the belt motor to be overloaded and damaged; when the pellets adhere to the belt more firmly, the scraper 3 cannot be used to scrape the pellets off the belt. By setting the cut angle 32, it is convenient for the pellets to push the scraper 3 downward, thereby preventing the utility model from being damaged by the scraper 3.

[0037] At the same time, the laser speed sensor 4 in the utility model can monitor the linear speed of the return section of the belt in real time. The zigbee module can transmit the linear speed monitored by the laser speed sensor 4 to the display screen on the control terminal and display it on the display screen, so that the staff can check the linear speed of the belt in real time. If the laser speed sensor 4 detects that the linear speed of the belt is lower than the normal operating speed of the belt for a long time (for example, the linear speed of the belt has been running at a speed lower than the normal operating speed of the belt for 5 minutes), the control terminal can control the alarm to send out an audible and visual alarm signal, thereby reminding the staff to check the belt operation in time to prevent damage to the belt motor.

[0038] When the scraper 3 is severely worn and needs to be replaced, the two clamping plates 221 can be moved in opposite directions by rotating the screw head 223, thereby loosening the scraper 3. At this time, the severely worn scraper block 31 can be replaced separately. After the replacement is completed, the screw head 223 is rotated in the opposite direction to move the two clamping plates 221 toward each other, thereby re-fixing and clamping the scraper 3.

[0039] In the above embodiment, the utility model provides a pellet ore burning lower roller screen belt monitoring device. By setting a sliding plate and a spring that can move up and down, the scraper in the utility model can be ensured to fit the return section of the belt under the action of the spring; the scraper in the utility model can be scraped off the pellets adhering to the belt, thereby preventing the pellets from adhering to the belt for a long time and causing a reduction in the belt running speed; the cutting angle can be set to facilitate the pellets to pass through the scraper when the pellets are firmly adhered to the belt and cannot be scraped off, thereby preventing the utility model from being damaged.

[0040] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary personnel in the field to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents of the present invention for protection have been fully recorded in the claims.
