Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a device for cleaning diaminoanthraquinone. Background Technology

[0002] 1,4-Diaminoanthraquinone leuco form is one of the commonly used raw materials in the dye industry. It has a wide range of applications and can be used to manufacture 2,3-dichloro-1,4-diaminoanthraquinone, 1,4-diaminoanthraquinone, or directly as a dye.

[0003] In existing technologies, after prolonged production of 1,4-diaminoanthraquinone, the reaction vessel often requires cleaning. Existing cleaning devices, such as the Chinese patent application number 202321067651.3 (a cleaning reaction apparatus for the synthesis of 1-aminoanthraquinone), use scrapers to continuously scrape the inner wall of the reaction vessel to achieve a cleaning effect. However, cleaning is not necessary at all times, and the scraper in the aforementioned device is constantly in contact with the inner wall of the reaction vessel, which easily causes unnecessary friction and wear. Over time, the scraper is prone to failure. Therefore, an improved device for cleaning 1,4-diaminoanthraquinone is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a device for cleaning diaminoanthraquinone, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A device for cleaning diaminoanthraquinone, comprising a reaction vessel, a feed pipe fixedly installed on one side of the upper end of the reaction vessel, and a stirring mechanism for stirring and reacting in the middle of the inner side of the reaction vessel, the stirring mechanism comprising a transmission rod, a reducer, a motor, a fixed rod, a movable rod, and a scraper, wherein the transmission rod is movably installed in the middle of the inner side of the reaction vessel via a bearing, the reducer is fixedly installed in the middle of the upper end of the reaction vessel, the power output shaft of the reducer is fixedly connected to the transmission rod, the motor is fixedly installed on one side of the reducer at the upper end of the reaction vessel, the power output terminal of the motor is drively connected to the power input shaft of the reducer, a plurality of fixed rods are uniformly fixedly installed on the surface of the transmission rod, a movable rod is movably inserted inside the movable rod, a scraper is fixedly installed at one end of the movable rod, and a transmission mechanism for pushing the scraper to open is provided inside the transmission rod.

[0006] Preferably, the transmission mechanism includes an electromagnet, a connecting rod, and a permanent magnet. An electromagnet is fixedly installed inside the transmission rod on one side of the fixed rod, and a connecting rod is fixedly installed at one end of the movable rod. A permanent magnet is fixedly installed at the end of the connecting rod near the electromagnet. When the electromagnet of this device is energized, a magnetic pole is generated, which then pushes the permanent magnet, the connecting rod, and the movable rod to move away from the electromagnet. This allows the scraper to adhere tightly to the inner sidewall of the reactor. Thus, when the transmission rod rotates, the inner sidewall of the reactor can be scraped and cleaned by the scraper.

[0007] Preferably, the electromagnet and the permanent magnet have the same magnetic poles. By applying the principle of like poles repelling each other, when the electromagnet is energized, it can repel the permanent magnet and the connecting rod and the movable rod from moving towards the inner side wall of the reactor.

[0008] Preferably, a spring is provided inside the fixed rod. One end of the spring is fixedly connected to the movable rod, and the end of the spring away from the movable rod is fixedly connected to the transmission rod. The spring can automatically drive the movable rod to reset, so that the movable rod and the scraper are away from the inner sidewall of the reactor.

[0009] Preferably, a base is fixedly provided at the lower end of the reactor, which can provide stable support for the reactor.

[0010] Preferably, a discharge pipe is fixedly installed on one side of the lower end of the reactor, through which the reacted raw materials can be discharged to await the next reaction stirring operation.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When the reaction vessel needs cleaning, the electromagnet can be powered. When the electromagnet is energized, it generates magnetic poles, which then push the permanent magnet, connecting rod, and movable rod to move away from the electromagnet. This allows the scraper to adhere tightly to the inner side wall of the reaction vessel. When the transmission rod rotates, the inner side wall of the reaction vessel can be scraped and cleaned by the scraper. When cleaning is not needed, the electromagnet is de-energized, and the movable rod and scraper can be reset by the action of the spring. This avoids unnecessary friction and wear, thus improving the cleaning effect of the device.

[0013] 2. This utility model is simple to use. It only requires energizing or de-energizing the electromagnet to control whether the scraper is attached to the inner side wall of the reactor. This makes it easy to control and use, and thus facilitates its promotion. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a device for cleaning diaminoanthraquinone, including a reaction vessel 1. A feed pipe 2 is fixedly installed on one side of the upper end of the reaction vessel 1. A stirring mechanism for stirring and reacting is installed in the middle of the inner side of the reaction vessel 1. The stirring mechanism includes a transmission rod 3, a reducer 13, a motor 14, a fixed rod 4, a movable rod 5, and a scraper 6. The transmission rod 3 is movably installed in the middle of the inner side of the reaction vessel 1 through a bearing. The reducer 13 is fixedly installed in the middle of the upper end of the reaction vessel 1. The power output shaft end of the reducer 13 is fixedly connected to the transmission rod 3. The motor 14 is fixedly installed on one side of the reducer 13 at the upper end of the reaction vessel 1. The power output terminal of the motor 14 is connected to the power input shaft end of the reducer 13. Several fixed rods 4 are evenly fixedly installed on the surface of the transmission rod 3. Movable rods 5 are movably inserted inside the movable rod 5. A scraper 6 is fixedly installed at one end of the movable rod 5. A transmission mechanism for pushing the scraper 6 to open is installed inside the transmission rod 3.

[0021] The transmission mechanism includes an electromagnet 7, a connecting rod 8, and a permanent magnet 9. An electromagnet 7 is fixedly installed inside the transmission rod 3 on one side of the fixed rod 4. A connecting rod 8 is fixedly installed at one end of the movable rod 5. A permanent magnet 9 is fixedly installed at the end of the connecting rod 8 near the electromagnet 7. When the electromagnet 7 of this device is energized, a magnetic pole is generated, which then pushes the permanent magnet 9, the connecting rod 8, and the movable rod 5 to move away from the electromagnet 7. This allows the scraper 6 to be tightly attached to the inner side wall of the reactor 1. When the transmission rod 3 rotates, the inner side wall of the reactor 1 can be scraped and cleaned by the scraper 6.

[0022] The electromagnet 7 and the permanent magnet 9 have the same magnetic pole. By means of the principle of like poles repelling each other, when the electromagnet 7 is energized, it can repel the permanent magnet 9 and the connecting rod 8 and the movable rod 5 to move towards the inner side wall of the reactor 1.

[0023] A spring 10 is provided inside the fixed rod 4. One end of the spring 10 is fixedly connected to the movable rod 5, and the end of the spring 10 away from the movable rod 5 is fixedly connected to the transmission rod 3. The spring 10 can automatically drive the movable rod 5 to reset, so that the movable rod 5 and the scraper 6 are away from the inner side wall of the reactor 1.

[0024] A base 11 is fixedly installed at the lower end of the reactor 1, which can provide stable support for the reactor 1.

[0025] A discharge pipe 12 is fixedly installed on one side of the lower end of the reactor 1. The reacted raw materials can be discharged through the discharge pipe 12 to wait for the next reaction stirring operation.

[0026] Working Principle: When using this device, the raw material for producing diaminoanthraquinone is injected into the reactor 1 through the feed pipe 2. Then, the transmission rod 3 is rotated by the motor 14 to perform stirring and reaction. At this time, the fixed rod 4 and the movable rod 5 act as stirring rods. After prolonged use, the inside of the reactor 1 needs to be cleaned. This is done by filling the reactor 1 with clean water through the feed pipe 2, and then rotating the transmission rod 3 again via the motor 14. At this time, the fixed rod 4, the movable rod 5, and the scraper 6 can rotate and come into contact with the clean water for self-cleaning. The inner side of the reactor 1... The sidewalls cannot be cleaned. In this case, power can be supplied to the electromagnet 7, which generates magnetic poles and pushes the permanent magnet 9, connecting rod 8, and movable rod 5 to move away from the electromagnet 7. This allows the scraper 6 to adhere tightly to the inner sidewall of the reactor 1. When the transmission rod 3 rotates, the inner sidewall of the reactor 1 can be scraped and cleaned by the scraper 6. When cleaning is not needed, the electromagnet 7 is de-energized, and the movable rod 5 and scraper 6 can be reset under the action of the spring 10. This avoids unnecessary friction and wear, thus improving the cleaning effect of the device.

[0027] It should be noted that the electromagnet 7 of this device requires a rotary power supply. Therefore, a brush (the rotary power supply structure in the motor 14) can be set on the outside of the transmission rod 3 to match the rotary power supply requirements of the electromagnet 7. However, since rotary power supply is a mature technology in the prior art, this application document will not elaborate on it further.

[0028] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, 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.
