Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a feeding device for a rotary kiln for titanium dioxide calcination. Background Technology

[0002] A feeding device is a device used to place raw materials into the rotary kiln. When using the feeding device, the raw material of titanium dioxide is carried to the top of the rotary kiln by a conveyor belt, so that the raw material can be placed into the interior of the rotary kiln through the feed port set at the top of the rotary kiln.

[0003] In their daily work, the inventors discovered that the feeding device still has at least the following problems: When using the feeding device, the raw material of titanium dioxide is carried to the top of the rotary kiln by a conveyor belt, so that the raw material can be put into the interior of the rotary kiln through the feed port set at the top of the rotary kiln. However, in actual use, the raw material of titanium dioxide is the intermediate titanium dioxide product after drying and dehydration. The intermediate product contains relatively large pieces of material, which makes it difficult for the intermediate powder to be heated evenly, thus affecting the calcination effect of titanium dioxide to a certain extent. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a feeding device for a rotary kiln for titanium dioxide calcination.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a feeding device for a rotary kiln for calcining titanium dioxide, comprising a support frame, a first motor fixedly connected to one side of the support frame, a rotating roller fixedly connected to the output end of the first motor, the rotating roller being rotatably inserted into the inner wall of the support frame, a first connecting belt sleeved on the surface of the two rotating rollers, an extrusion device provided at the top of the support frame, an adjustment device provided on one side of the support frame, the extrusion device comprising a connecting frame, the connecting frame being provided at the top of the support frame, extrusion rollers being uniformly rotatably inserted into the inner wall of the connecting frame, the distance between the central axis of the extrusion roller and the top of the first connecting belt being consistent, and the radius of the extrusion roller gradually increasing from bottom to top.

[0006] The effect achieved by the above components is as follows: when the extrusion device is used, as the material passes through the bottom of multiple extrusion rollers via the first connecting belt, the radius of the extrusion rollers gradually increases, and the top of the inner wall of the first connecting belt is set on the top of the fixed plate in the support frame. This can effectively crush large pieces of raw material, so that the raw material entering the rotary kiln can be effectively calcined.

[0007] Preferably, each of the extrusion rollers is fixedly connected to a first pulley at the end away from the connecting frame, and a second connecting belt is sleeved on the surface of the two first pulleys. A second motor is fixedly connected to the side of the connecting frame away from the first pulley, and the output end of the second motor is fixedly connected to one end of the extrusion roller.

[0008] The effect achieved by the above components is that the second motor drives one of the extrusion rollers to rotate, and multiple connecting belts are respectively fitted onto the surfaces of two adjacent first pulleys, so that all the extrusion rollers can be driven to rotate in the same direction.

[0009] Preferably, a connecting frame is uniformly fixedly connected to the top of the connecting frame, a damping rod is fixedly connected to the bottom of the inner wall of the connecting frame, a scraper is fixedly connected to the bottom of the damping rod, a first spring is sleeved on the surface of the damping rod, the top of the first spring is fixedly connected to the top of the inner wall of the connecting frame, the end of the first spring near the damping rod is fixedly connected to the top of the scraper, and the scraper is disposed on the top of the extrusion roller.

[0010] The effect achieved by the above components is that the scraper is squeezed towards the first connecting belt by the first spring, so that the scraper can be squeezed well on the top of the extrusion roller, thus scraping off the raw material stuck to the surface of the extrusion roller, thereby improving the raw material utilization rate to a certain extent.

[0011] Preferably, the top of the support frame is provided with a rectangular groove, and a rectangular strip is slidably connected to the inner wall of the rectangular groove. The top of the rectangular strip is fixedly connected to the bottom of the connecting frame. A fixing rod is slidably inserted into one side of the support frame. The fixing rod is slidably inserted through one side of the rectangular strip. A second spring is sleeved on the surface of the fixing rod. One end of the second spring is fixedly connected to one end of the fixing rod. The end of the second spring near the fixing rod is fixedly connected to one side of the support frame.

[0012] The effect achieved by the above components is as follows: the rectangular bar is slid into the interior of the rectangular groove, the fixing rod is then inserted into the interior of the rectangular groove, the fixing rod passes through one side of the rectangular bar, and the fixing rod is pulled towards the support frame by the second spring, thereby effectively confining the fixing rod inside the rectangular bar.

[0013] Preferably, the adjusting device includes a rotating rod, which is rotatably inserted into one side of the support frame, and a rotating frame is fixedly connected to the end of the rotating rod away from the support frame.

[0014] The effect achieved by the above components is as follows: when using the adjustment device, the rotating rod is manually rotated by rotating the frame, and the end of the rotating frame away from the support frame is set at the top of the feed inlet, which facilitates the raw material to be transported into the feed inlet.

[0015] Preferably, a rotating wheel is rotatably inserted into the bottom of the inner wall of the rotating frame, and a second pulley is fixedly connected to the end of the rotating wheel away from the rotating frame. A third motor is fixedly connected to the bottom of the rotating frame, and a third pulley is fixedly connected to the output end of the third motor. A third connecting belt is sleeved on the surface of the two second pulleys and the third pulley.

[0016] The effect achieved by the above components is that the third motor drives the third pulley to rotate, which in turn drives the rotating wheel to rotate through the third connecting belt, thus facilitating the extrusion of the raw material from the corner of the rotating frame.

[0017] Preferably, a bolt is fixedly connected to the side of the rotating frame away from the support frame, a connecting ring is sleeved on the surface of the bolt, a positioning rod is fixedly connected to one side of the connecting ring, the end of the positioning rod away from the connecting ring is fixedly connected to one side of the support frame, and a circular plate is threaded onto the surface of the bolt.

[0018] The effect achieved by the above components is that the circular plate is manually controlled to move on the surface of the bolt, thereby pressing the circular plate against one side of the connecting ring, which makes it easier to restrict the rotating frame to one side of the positioning rod.

[0019] Preferably, a protrusion is uniformly fixedly connected to one side of the circular plate, and a rubber ring is fixedly connected to one side of the protrusion. The rubber ring and one side of the connecting ring are fixedly connected.

[0020] The effect achieved by the above components is that when the circular plate is pressed against one side of the connecting ring, the protrusion is pressed against one side of the rubber ring, thereby causing the rubber to be squeezed and deformed, which can effectively restrict the circular plate to one side of the connecting ring.

[0021] In this invention, by setting up an extrusion device, when the material passes through the bottom of multiple extrusion rollers via the first connecting belt, the radius of the extrusion rollers gradually increases, and the top of the inner wall of the first connecting belt is set on the top of the fixed plate in the support frame. This can effectively crush large pieces of raw material, allowing the raw material entering the rotary kiln to be calcined effectively. Attached Figure Description

[0028] Example 1, such as Figure 1-5 As shown, a feeding device for a rotary kiln for calcining titanium dioxide includes a support frame 1 with a first motor 2 fixedly connected to one side. The output end of the first motor 2 is fixedly connected to a rotating roller 3, which is rotatably inserted into the inner wall of the support frame 1. The surfaces of the two rotating rollers 3 are fitted with first connecting belts 4. A pressing device 5 is provided on the top of the support frame 1, and an adjusting device 6 is provided on one side of the support frame 1. When using the feeding device, the raw material of titanium dioxide is driven to the top of the rotary kiln by the conveyor belt, so that the raw material can be placed into the interior of the rotary kiln through the feed inlet provided on the top of the rotary kiln.

[0029] Reference Figure 2 and Figure 3The extrusion device 5 includes a connecting frame 501, which is located on top of the support frame 1. Extrusion rollers 502 are evenly rotatably inserted into the inner wall of the connecting frame 501. The central axis of the extrusion rollers 502 is at the same distance from the top of the first connecting belt 4. The radius of the extrusion rollers 502 gradually increases from bottom to top. When using the extrusion device 5, as the material passes through the bottom of multiple extrusion rollers 502 via the first connecting belt 4, the gradually increasing radius of the extrusion rollers 502, and the top of the inner wall of the first connecting belt 4 being positioned on the top of the fixed plate in the support frame 1, effectively crushes large pieces of raw material. This allows the raw material entering the rotary kiln to be effectively calcined. The end of the extrusion rollers 502 furthest from the connecting frame 501 is uniformly fixed. A first pulley 508 is fixedly connected to the frame 501. A second connecting belt 509 is fitted onto the surface of the two first pulleys 508. A second motor 507 is fixedly connected to the side of the frame 501 away from the first pulleys 508. The output end of the second motor 507 is fixedly connected to one end of the extrusion roller 502. The second motor 507 drives one of the extrusion rollers 502 to rotate. Multiple connecting belts are respectively fitted onto the surfaces of two adjacent first pulleys 508, thus driving all the extrusion rollers 502 to rotate in the same direction. A connecting frame 510 is evenly fixedly connected to the top of the frame 501. A damping rod 511 is fixedly connected to the bottom of the inner wall of the connecting frame 510. A scraper 513 is fixedly connected to the bottom of the damping rod 511. A first spring 512 is fitted onto the surface of the connecting frame 511. The top of the first spring 512 is fixedly connected to the top of the inner wall of the connecting frame 510. One end of the first spring 512 near the damping rod 511 is fixedly connected to the top of the scraper 513. The scraper 513 is positioned on top of the extrusion roller 502. The first spring 512 presses the scraper 513 towards the first connecting belt 4, allowing the scraper 513 to effectively press against the top of the extrusion roller 502. This scrapes off the material adhering to the surface of the extrusion roller 502, thereby improving the material utilization rate to a certain extent. A rectangular groove 503 is provided on the top of the support frame 1. A rectangular strip 504 is slidably connected to the inner wall of the rectangular groove 503. The top of the rectangular strip 504 is connected to the connecting frame 501. The bottom is fixedly connected, and a fixing rod 505 is slidably inserted into one side of the support frame 1. The fixing rod 505 is slidably inserted through one side of the rectangular bar 504. A second spring 506 is sleeved on the surface of the fixing rod 505. One end of the second spring 506 is fixedly connected to one end of the fixing rod 505. The end of the second spring 506 near the fixing rod 505 is fixedly connected to one side of the support frame 1. The rectangular bar 504 is slid into the rectangular groove 503, and then the fixing rod 505 is inserted into the rectangular groove 503. The fixing rod 505 passes through one side of the rectangular bar 504, and the second spring 506 pulls the fixing rod 505 towards the support frame 1, thereby effectively restricting the fixing rod 505 inside the rectangular bar 504.

[0030] Reference Figure 4 and Figure 5 The adjusting device 6 includes a rotating rod 601, which is rotatably inserted into one side of the support frame 1. A rotating frame 602 is fixedly connected to the end of the rotating rod 601 away from the support frame 1. When using the adjusting device 6, the rotating rod 601 is manually rotated via the rotating frame 602, thereby positioning the end of the rotating frame 602 away from the support frame 1 at the top of the feed inlet. This facilitates the conveying of raw materials into the feed inlet. A rotating wheel 603 is rotatably inserted into the bottom of the inner wall of the rotating frame 602. A second pulley 606 is fixedly connected to the end of each rotating wheel 603 away from the rotating frame 602. A third motor 604 is fixedly connected to the bottom of the rotating frame 602. A third pulley 605 is fixedly connected to the output end of the third motor 604. A third connecting belt 607 is fitted onto the surfaces of both second pulleys 606 and the third pulley 605. The third motor 604 drives the third pulley 605 to rotate, which in turn drives the rotating wheel 603 to rotate via the third connecting belt 607. This facilitates the adjustment of the rotating frame 602. The raw material at the corner is extruded. A bolt 610 is fixedly connected to the side of the rotating frame 602 away from the support frame 1. A connecting ring 609 is fitted on the surface of the bolt 610. A positioning rod 608 is fixedly connected to one side of the connecting ring 609. The end of the positioning rod 608 away from the connecting ring 609 is fixedly connected to one side of the support frame 1. A circular plate 611 is threaded onto the surface of the bolt 610. The circular plate 611 is manually controlled to move on the surface of the bolt 610, thereby causing the circular plate 611 to press against one side of the connecting ring 609. The circular plate 611 is positioned on one side, which makes it easier to restrict the rotating frame 602 to one side of the positioning rod 608. A protrusion 612 is evenly fixedly connected to one side of the circular plate 611, and a rubber ring 613 is fixedly connected to one side of the protrusion 612. The rubber ring 613 is fixedly connected to one side of the connecting ring 609. When the circular plate 611 is pressed against one side of the connecting ring 609, the protrusion 612 is pressed against one side of the rubber ring 613, which causes the rubber to be squeezed and deformed. This can effectively restrict the circular plate 611 to one side of the connecting ring 609.

[0031] Working principle: When using the feeding device, the titanium dioxide raw material is carried to the top of the rotary kiln by a conveyor belt, allowing it to enter the kiln through the feed inlet at the top. When using the extrusion device 5, the rectangular bar 504 is slid into the rectangular groove 503, and the fixing rod 505 is inserted into the rectangular groove 503, passing through one side of the rectangular bar 504. The second spring 506 pulls the fixing rod 505 towards the support frame 1, effectively confining the fixing rod 505 within the rectangular bar 504. Inside, a second motor 507 drives one of the extrusion rollers 502 to rotate. Multiple connecting belts are respectively fitted onto the surfaces of two adjacent first pulleys 508, thus driving all the extrusion rollers 502 to rotate in the same direction. When the material passes through the bottom of the multiple extrusion rollers 502 via the first connecting belt 4, because the radius of the extrusion rollers 502 gradually increases and the top of the inner wall of the first connecting belt 4 is positioned on the top of the fixed plate in the support frame 1, large pieces of raw material can be effectively crushed. At the same time, the material is squeezed towards the first connecting belt 4 by the first spring 512. The scraper 513 is designed to effectively press against the top of the extrusion roller 502, scraping off the raw material adhering to its surface and thus improving material utilization. This allows the raw material entering the rotary kiln to be effectively calcined. When using the adjustment device 6, the rotating frame 602 is manually rotated to drive the rotating rod 601, and the circular plate 611 is manually moved on the surface of the bolt 610, causing it to press against one side of the connecting ring 609. When the circular plate 611 presses against one side of the connecting ring 609... The protrusion 612 presses against one side of the rubber ring 613, causing the rubber to be deformed. This effectively restricts the circular plate 611 to one side of the connecting ring 609, which in turn restricts the rotating frame 602 to one side of the positioning rod 608. The end of the rotating frame 602 away from the support frame 1 is then positioned at the top of the feed inlet. At the same time, the third motor 604 drives the third pulley 605 to rotate, which in turn drives the rotating wheel 603 to rotate via the third connecting belt 607. This facilitates the extrusion of the raw material at the corner of the rotating frame 602, making it easier for the raw material to be transported into the feed inlet.

[0032] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
