Description

Technical Field

[0001] The utility model relates to the technical field of reactor cleaning devices, and particularly relates to a cleaning device for a reactor used in the production of anhydrous hydrogen fluoride. Background Technique

[0002] Anhydrous hydrogen fluoride is mainly prepared by a rotary furnace. During the preparation, calcium fluoride raw materials and mixed acid are stirred and mixed in a certain proportion by a screw conveyor, and then enter an inclined rotary furnace through a feed pipe for heating reaction. The rotary furnace is heated by a flue gas heating jacket. The heating reaction generates hydrogen fluoride gas and waste residue fluorogypsum. The hydrogen fluoride is discharged from the tail pipe, and the waste residue fluorogypsum needs to move to the furnace tail by gravity for discharge.

[0003] At present, the slag discharge area of the reactor needs to be cleaned in time. Otherwise, when discharging slag, if the cleaning is not timely, the previous waste residue cannot be discharged in time, and the subsequent discharged waste residue is very likely to block the slag discharge port. At the same time, after a long time of slag discharge, a lot of fluorogypsum slag is easily attached to the inner wall of the slag discharge port, but it is not very convenient for the staff to clean, and it is very easy to cause excessive attachment of impurities on the surface, affecting the overall service life. Content of the Utility Model

A connecting plate is connected to the tops of the two blanking plates. Rotating rods are fixed at both ends of the connecting plate, and the rotating rods are rotatably arranged on the inner wall of the slag discharge pipe. Two symmetrically arranged connecting rods are hinged to the mutually remote sides of the two blanking plates through hinge blocks. The ends of the adjacent two connecting rods away from the blanking plates are movably inserted into the slag discharge pipe. The ends of the two connecting rods penetrating through the slag discharge pipe are commonly connected to a fixing plate. A first spring is sleeved on the end of the connecting rod located outside the slag discharge pipe, and both ends of the first spring are respectively fixed on the side wall of the slag discharge pipe and the fixing plate. A horizontally arranged support plate is fixed below one of the fixing plates on the outer wall of the slag discharge pipe. A rotating shaft is rotatably arranged on the support plate. A circular top plate is arranged at the top of the rotating shaft, and the top plate can abut against the fixing plate. The rotating shaft is fixedly arranged at the eccentric position of the top plate. A connecting component is arranged between the two fixing plates.

[0006] Preferably, two symmetrically arranged mounting blocks are fixedly provided on one side of the connecting plate close to the blanking plate. Mounting grooves corresponding to the mounting blocks are formed at the top of the blanking plate. A groove is formed at the top of the blanking plate between the two mounting grooves.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment: As Figures 1-5 shown, the present invention provides a cleaning device for a reaction furnace used in the production of anhydrous hydrogen fluoride, including a reactor body 1. A feed end 11 is installed at the top of the reactor body 1. An exhaust pipe 12 is installed above the reactor body 1 away from the feed end 11. A slag discharge pipe 13 is provided below the exhaust pipe 12 of the reactor body 1. Two inclined and symmetrically distributed feeding plates 14 are provided inside the slag discharge pipe 13. A connecting plate 15 is connected to the tops of the two feeding plates 14. Rotating rods 16 are fixedly provided at both ends of the connecting plate 15 and the rotating rods 16 are rotatably arranged on the inner wall of the slag discharge pipe 13. Two symmetrically arranged connecting rods 2 are hinged to the two feeding plates 14 on the sides away from each other through hinge blocks 5. The ends of the adjacent two connecting rods 2 away from the feeding plates 14 are movably inserted into the slag discharge pipe 13. The ends of the two connecting rods 2 passing through the slag discharge pipe 13 are commonly connected to a fixed plate 21. A first spring 26 is sleeved on the end of the connecting rod 2 located outside the slag discharge pipe 13. The two ends of the first spring 26 are respectively fixed on the side wall of the slag discharge pipe 13 and the fixed plate 21. A horizontally arranged support plate 22 is fixed on the outer wall of the slag discharge pipe 13 below one of the fixed plates 21. A rotating shaft 23 is rotatably provided on the support plate 22. A circular top plate 24 is provided at the top of the rotating shaft 23. The top plate 24 can abut against the fixed plate 21. The rotating shaft 23 is fixedly arranged at the eccentric position of the top plate 24. A connecting component is provided between the two fixed plates 21.

[0019] A driving motor 25 is fixedly installed at the bottom of the support plate 22. The output end of the driving motor 25 is coaxially fixedly arranged on the rotating shaft 23. The provided driving motor 25 can provide power for the rotating shaft 23 to rotate and work, which is convenient for the staff to operate.

[0020] The connecting component includes a first gear 32, which is arranged on the outer wall of the slag discharge pipe 13 on the side adjacent to the two fixing plates 21. A first toothed plate 33 arranged diagonally is jointly engaged on the first gear 32. At the ends of the two first toothed plates 33 away from the first gear 32, a fixing rod 31 arranged in an L shape is fixed. The end of the fixing rod 31 away from the first gear 32 is fixed on the adjacent fixing plate 21. By means of the arranged first gear 32 and first toothed plate 33, the two fixing plates 21 can move towards each other or away from each other simultaneously, so as to control the separation or closing operation between the two blanking plates 14 at the same time; on the side of the outer wall of the slag discharge pipe 13 close to the first gear 32 and the first toothed plate 33, a protective plate 3 is fixed. The first gear 32 rotates inside the protective plate 3, and the first toothed plate 33 is slidably arranged on the side wall of the protective plate 3. The arranged protective plate 3 provides support for the rotation of the first gear 32 and stability for the movement of the first toothed plate 33.

[0021] On the side of the connecting plate 15 close to the blanking plate 14, two symmetrically arranged mounting blocks 4 are fixed. On the top of the blanking plate 14, mounting grooves 42 corresponding to the mounting blocks 4 are opened. Between the two mounting grooves 42 on the top of the blanking plate 14, a groove 43 is opened. At both ends of the groove 43, a stop rod 47 is movably inserted. The mounting block 4 is provided with a stop groove 41 that coincides with the stop rod 47. When the mounting groove 42 is inserted into the mounting groove 42 and the stop rod 47 is inserted into the stop groove 41 on the mounting block 4, the double fixation between the connecting plate 15 and the blanking plate 14 is completed, so as to ensure that the blanking plate 14 can be firmly installed along with the connecting plate 15; at the bottom of the connecting plate 15, a driving rod 44 is rotatably inserted. The top of the driving rod 44 rotates in the middle end of the groove 43 and is fixed with a second gear 45. Two second toothed plates 46 arranged diagonally are engaged on the second gear 45. At the ends of the two second toothed plates 46 away from the second gear 45, they are fixed on the stop rod 47. The staff can rotate the driving rod 44 to drive the second gear 45 to rotate clockwise, so that the two second toothed plates 46 move towards each other at the same time, and finally the two second toothed plates 46 drive the stop rod 47 to disengage from the stop groove 41. Then, after the staff removes the hinge block 5, the blanking plate 14 can be directly pulled down to complete the disassembly of the blanking plate 14, which is convenient for the staff to replace or clean it, and convenient for its maintenance, thereby improving its service life; a second spring 48 is jointly connected between the two second toothed plates 46. The arranged second spring 48 can always push the two second toothed plates 46 to separate from each other, so as to ensure that the stop rod 47 on the second toothed plate 46 is stably inserted into the stop groove 41, increasing the stability of the installation of the blanking plate 14 of the device.

[0022] The articulated block 5 is actually composed of two jointly rotatable block bodies. One end of the articulated block 5 is fixed on the connecting rod 2, and the other end of the articulated block 5 is fixed with a cylindrical block inserted into the blanking plate 14. Through the above operations, the connection between the blanking plate 14 and the connecting rod 2 can be facilitated.

[0023] Working principle: During use, the driving motor 25 can drive the rotation shaft 23 to rotate. At this time, the top plate 24 with a bias setting on the rotation shaft 23 will abut against the fixed plate 21. At this time, the fixed plate 21 will drive the two connecting rods 2 to move away from one end of the slag discharge pipe 13 at the same time. Since the first gear 32 and the first toothed plate 33 are provided, the two fixed plates 21 can move towards or away from each other at the same time. When the fixed plate 21 is pushed by the top plate 24 to move away from the slag discharge pipe 13, the other fixed plate 21 will also move away from the slag discharge pipe 13 at the same time. At this time, the two blanking plates 14 in the slag discharge pipe 13 will move away from each other at the same time, increasing the space for discharging slag at the bottom. As the top plate 24 rotates and no longer contacts the fixed plate 21, at this time, the first spring 26 will pull the fixed plate 21 to move towards the slag discharge pipe 13. At the same time, the two fixed plates 21 will drive the connecting rods 2 to reduce the space at the bottom of the two blanking plates 14. As the driving motor 25 continuously drives the top plate 24 to move, the space at the bottom of the two blanking plates 14 will continuously change, and at the same time, the blanking plate 14 can also push the waste residue to move, so as to ensure the normal discharge of the bottom of the slag discharge pipe 13 and prevent blockage. Through the above operations, when the staff cleans the inside of the slag discharge pipe 13 to avoid blockage, they can directly start the driving motor 25 to complete the cleaning of the filter residue in the slag discharge pipe 13, ensure its normal discharge, and make the later cleaning work of the slag discharge pipe 13 time-saving and labor-saving;

[0024] When it is necessary to disassemble, replace and repair the blanking plate 14, the staff can directly rotate the driving rod 44 to drive the second gear 45 to rotate clockwise, so that the two second toothed plates 46 move towards each other at the same time. Finally, the two second toothed plates 46 will drive the stop rod 47 to disengage from the stop groove 41. Then, the staff can pull out the articulated block 5 and directly pull down the blanking plate 14 to complete the disassembly of the blanking plate 14, which is convenient for the staff to replace or clean it, and convenient for its maintenance, thereby improving its service life.

[0025] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations.
