Heavy-duty double chain scraper and titanium dioxide production line

Abstract

The application discloses a heavy-load double-chain scraper and a titanium dioxide production line. The chain breakage protector can detect the rotating speed of the supporting wheel set on the two sides of the box. If a single chain breaks, gets stuck, loses a pin or is loose, the rotating speed of the supporting wheel set corresponding to the broken chain changes abnormally. Therefore, when the chain breakage protector detects abnormal change of the rotating speed of the supporting wheel set on any side of the box, the driving assembly is controlled to stop, so that the action of the chain is stopped. In this way, when the double chains are out of synchronization, the material conveying is stopped in time, the chain is prevented from being torn, and the problem that the equipment is damaged due to material accumulation is avoided, so that the service life of the equipment is guaranteed.

Description

Technical Field

[0001] This application relates to the field of titanium dioxide production technology, and in particular to a heavy-duty double-chain scraper conveyor and a titanium dioxide production line. Background Technology

[0002] Titanium dioxide (TiO2) is a widely used white pigment, renowned for its excellent hiding power, brightness, and chemical stability. It is one of the most widely used white pigments in the world, with applications in coatings, plastics, paper, inks, cosmetics, and many other fields.

[0003] In the production of titanium dioxide, the media such as titanium ore and petroleum tar have high density, so a heavy-duty double-chain scraper conveyor is used for conveying. The heavy-duty double-chain scraper conveyor uses the synchronous operation of the two chains to drive the scraper to convey materials. If a single chain breaks, the pin falls off, or it becomes loose, it will cause the two chains to become out of sync, resulting in chain tearing, material accumulation, and serious equipment damage. Utility Model Content

[0004] The purpose of this application is to provide a heavy-duty double-chain scraper conveyor and titanium dioxide production line that can stop conveying materials in time when the double chains are out of sync, so as to avoid chain tearing and material accumulation that could damage the equipment and thus ensure the service life of the equipment.

[0005] The embodiments of this application can be implemented as follows:

[0006] In a first aspect, this utility model provides a heavy-duty double-chain scraper conveyor, including a housing, chain, scraper, drive assembly, roller assembly, and chain breakage protector;

[0007] The two sides of the box are respectively equipped with rotatable roller sets;

[0008] Two chains are respectively supported on the roller assemblies on both sides of the box body;

[0009] The scraper is fixed to the chain, and the length direction of the scraper is perpendicular to the length direction of the chain, and the surface of the scraper is inclined relative to the chain;

[0010] The drive assembly is connected to the chain drive;

[0011] The chain breakage protector can control the drive assembly to stop based on the rotational speed of the rollers on both sides of the housing.

[0012] In an optional embodiment, the chain break protector includes a speed sensor and a controller, both of which are electrically connected to the controller.

[0013] The speed sensors are installed on both sides of the housing to detect the rotational speed of the wheel sets on both sides of the housing, respectively.

[0014] The controller can stop the drive assembly based on the detection results of the speed sensor.

[0015] In an optional embodiment, there are two roller sets and two speed sensors. Each roller set supports one chain, and each speed sensor is used to detect the rotational speed of a corresponding roller set.

[0016] In an optional embodiment, the roller assembly includes a roller, a roller shaft, a bearing, and a bracket. The bracket is fixed to the side wall of the housing, the bearing is installed inside the bracket, the roller shaft is fixedly inserted through the bearing, and the roller is fitted onto the roller shaft. The roller is used to support the chain.

[0017] The speed sensor is used to detect the rotational speed of the roller shaft.

[0018] In an optional embodiment, the bracket is fixed to the outside of the side wall of the box, the roller shaft passes through the side wall of the box to extend into the box, and the roller is located on the inside of the box.

[0019] In an optional embodiment, the roller is provided with a threaded hole that radially penetrates its outer and inner peripheral walls, and a set screw is threaded into the threaded hole and abuts against the roller shaft.

[0020] In an optional embodiment, the outer peripheral wall of the roller is provided with an annularly extending groove.

[0021] In an optional embodiment, the heavy-duty double-chain scraper conveyor further includes an alarm that activates when the chain breakage protector controls the drive assembly to stop.

[0023] Secondly, this utility model provides a titanium dioxide production line, including the heavy-duty double-chain scraper conveyor described in any of the foregoing embodiments.

[0024] The beneficial effects of the embodiments of this application include, for example:

[0025] The chain breakage protector can detect the rotational speed of the roller assemblies on both sides of the box. If a single chain breaks, jams, pins fall off, or loosens, the rotational speed of the roller assembly corresponding to the chain that is faulty will change abnormally. Therefore, when the chain breakage protector detects an abnormal change in the rotational speed of the roller assemblies on either side of the box, it controls the drive component to stop, thereby stopping the chain's movement. This allows for timely cessation of material conveying when the two chains become asynchronous, preventing chain tearing, material accumulation, and equipment damage, thus ensuring the equipment's service life.

[0037] The following is combined Figures 1 to 3 This application provides a detailed description of some embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] This application discloses a heavy-duty double-chain scraper conveyor, which includes a housing 10, a chain 20, a scraper 30, a drive assembly, a roller group 40, and a chain breakage protector.

[0039] Roller assemblies 40 are rotatably mounted on both sides of the housing 10;

[0040] Two chains 20 are respectively supported on the roller assemblies 40 on both sides of the housing 10;

[0041] The scraper 30 is fixed to the chain 20, and the length direction of the scraper 30 is perpendicular to the length direction of the chain 20. The surface of the scraper 30 is inclined relative to the chain 20, for example, at 60°, to facilitate material conveying.

[0042] The drive assembly is connected to the chain 20 for transmission;

[0043] The chain breakage protector can control the drive assembly to stop based on the rotational speed of the roller assemblies 40 on both sides of the housing 10.

[0044] In this way, the chain breakage protector can detect the rotational speed of the roller groups 40 on both sides of the housing 10. If a single chain breaks, jams, pins fall off, or loosens, the rotational speed of the corresponding roller group 40 of the chain 20 that is malfunctioning will change abnormally. Therefore, when the chain breakage protector detects an abnormal change in the rotational speed of the roller group 40 on either side of the housing 10, it controls the drive component to stop, thereby stopping the movement of the chain 20. This allows for timely stopping of material conveying when the two chains become asynchronous, preventing the chain 20 from tearing, material accumulation from causing equipment damage, and thus ensuring the service life of the equipment.

[0045] It should be noted that the drive assembly used to drive the chain 20 can adopt the common method of driving the sprocket with a drive motor. That is, the drive assembly includes a drive motor, a drive sprocket, and a driven sprocket. The drive sprocket and the driven sprocket are rotatably mounted on the housing 10 and are distributed at intervals along the conveying direction. The chain 20 is wound around the drive sprocket and the driven sprocket. The roller group 40 is located between the drive sprocket and the driven sprocket and supports the chain 20. The drive motor and the drive sprocket can be connected by a reducer so that when the drive motor is running, it drives the drive sprocket to rotate, and then the chain 20 drives the driven sprocket and the roller group 40 to rotate.

[0046] In detail, the chain break protector includes a speed sensor and a controller, and the speed sensor and the drive motor of the drive assembly are both electrically connected to the controller.

[0047] Speed ​​sensors are installed on both sides of the housing 10 to detect the rotational speed of the wheel sets on both sides of the housing 10 respectively;

[0048] The controller can stop the drive components based on the detection results of the speed sensor.

[0049] In this way, the speed of the roller group 40 set on the same side is detected by a speed sensor on one side of the housing 10, and the speed of the roller group 40 set on the same side is detected by a speed sensor on the other side of the housing 10. As long as the speed of the corresponding roller group 40 detected by the speed sensor on either side changes abnormally, such as the speed dropping to or exceeding the set value, or for example, the speed sensor automatically detects the average speed of the roller group 40. If the speed is lower or higher than the average speed, then the controller can control the drive motor to stop, the corresponding drive components to stop, and the equipment to stop conveying materials.

[0050] Specifically, there are two roller sets 40 and two speed sensors. Each roller set 40 supports one chain 20, and each speed sensor is used to detect the rotational speed of a corresponding roller set 40. In this way, only two roller sets 40 and two speed sensors are needed. Each speed sensor detects the rotational speed of a corresponding roller set 40. The controller processes less data, and the number of hardware components is also less, resulting in lower cost.

[0051] Understandably, the controller can also compare the difference between the detection results of the two speed sensors and determine whether the two chains are out of sync by comparing the difference with the set difference.

[0052] In this embodiment, the roller assembly 40 includes a roller 45, a roller shaft 43, a bearing 42, and a bracket 41. The bracket 41 is fixed to the side wall of the housing 10, the bearing 42 is installed inside the bracket 41, the roller shaft 43 is fixedly inserted through the bearing 42, and the roller 45 is fitted onto the roller shaft 43. The roller 45 is used to support the chain 20. The speed sensor is used to detect the rotational speed of the roller shaft 43.

[0053] The bracket 41 is fixed to the outside of the side wall of the housing 10, the roller axle 43 passes through the side wall of the housing 10 to extend into the housing 10, and the roller 45 is located inside the housing 10. In this way, the housing 10 can protect the chain 20 and the roller assembly 40.

[0054] The support roller 45 is provided with a threaded hole 450 that radially penetrates its outer and inner peripheral walls. The set screw 46 is threaded into the threaded hole 450 and abuts against the support roller shaft 43 to fix the support roller 45.

[0055] The outer peripheral wall of the roller 45 is provided with an annularly extending groove 451 to adapt to the shape of the chain 20 and the scraper 30, while increasing the mating area between the roller 45 and the chain 20 and preventing slippage between the roller 45 and the chain 20.

[0056] The heavy-duty double-chain scraper conveyor also includes an alarm. When the chain breakage protector controls the drive assembly to stop, the alarm will be activated. That is, when the speed sensor on either side of the housing 10 detects an abnormal change in the rotational speed of the roller shaft 43, the controller will control the drive motor to stop and at the same time, the controller will also control the alarm to be activated to issue an alarm signal, so that workers can restart the equipment after inspection.

[0057] The length of the scraper 30 is greater than the distance between the two chains 20, and both ends of the scraper 30 are connected to the two chains 20 respectively, which facilitates the conveying of materials.

[0058] It is understood that the aforementioned controller is typically a central processing unit (CPU), which can be configured with a corresponding operating system and control interface, etc. Specifically, it can be a microcontroller, DSP (Digital Signal Processing), ARM (Advanced RISC Machines), or other digital logic control unit capable of automation control. It can load control instructions into memory for storage and execution at any time. At the same time, it can have built-in CPU instruction and data memory, input / output units, power supply modules, digital and analog units, etc. The specific configuration can be set according to the actual use situation, and the embodiments of this application do not limit this.

[0059] In addition, this application also discloses a titanium dioxide production line, which includes the heavy-duty double-chain scraper conveyor of the above embodiment, and therefore also has the corresponding structure and beneficial effects.

[0060] In summary, this application discloses a heavy-duty double-chain scraper conveyor and a titanium dioxide production line. The chain breakage protector can detect the rotational speed of the roller groups 40 on both sides of the housing 10. If a single chain breaks, jams, pins fall off, or loosens, the rotational speed of the roller group 40 corresponding to the chain 20 that malfunctions will also change abnormally. Therefore, when the chain breakage protector detects an abnormal change in the rotational speed of the roller group 40 on either side of the housing 10, it controls the drive component to stop, thereby stopping the movement of the chain 20. This allows for timely stopping of material conveying when the two chains become asynchronous, preventing chain 20 tearing, material accumulation, and equipment damage, thus ensuring the service life of the equipment.

[0061] Finally, it should be noted that in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0062] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
