Description

Technical Field

[0001] This utility model relates to the field of calcium chloride preparation technology, specifically to a preparation device for industrial calcium chloride from produced water from high-salinity gas fields. Background Technology

[0002] Industrial calcium chloride is classified into anhydrous calcium chloride, dihydrate calcium chloride, and liquid calcium chloride. It is primarily used as a refrigerant, antifreeze, de-icing agent, and anti-fogging / dust-removing agent. Industrial calcium chloride is generally produced from distillation waste liquid during the ammonia-soda process for producing soda ash. After sedimentation to remove solid impurities, it is evaporated and concentrated to remove sodium chloride. Once concentrated to 68-70% calcium chloride, it is then fed into a flake forming machine for flake production. The concentration process for dihydrate calcium chloride utilizes a concentration tank. Currently, concentration tanks are mainly equipped with evaporation heating mechanisms and stirring mechanisms to promote solution flow. During concentration, raw material residue may remain on the inner wall of the tank. The stirring mechanism inside the tank can interfere with cleaning the inner wall, and the solidification of residue after drying further complicates the cleaning process.

[0003] The utility model with publication number CN221229957U discloses a concentration tank for extracting calcium chloride dihydrate, including a concentration tank body. An evaporation chamber is set inside the concentration tank body. A rinsing mechanism is set in the evaporation chamber of the concentration tank body. The rinsing mechanism includes a hollow rotating shaft, a stirring plate, a rotating bearing, a rotating pipe and a strip-shaped spray hole. The hollow rotating shaft is rotatably connected to the center of the internal area of ​​the concentration tank body.

[0004] As shown in the above utility model, existing calcium chloride preparation concentration tanks generally use a rotatable baffle and spray holes to clean the inner wall of the concentration tank. In this method, the baffle is attached to the inner wall of the concentration tank by an adjustable wall-mounted scraper. This setting has two problems: firstly, the wall-mounted scraper may separate from the concentration tank when the baffle rotates due to loosening of the clamping bolts; secondly, the wall-mounted scraper may damage the inner wall of the concentration tank after scraping for a long time.

[0027] Please see Figure 1-5 This utility model provides two technical solutions:

[0028] The first embodiment: a device for preparing industrial calcium chloride from produced water from high-salinity gas fields, including a concentration tank 1, a rotating component 2, a connecting component 3, and a cleaning component 4. A geared motor 11 is installed at the bottom center of the concentration tank 1, and a cover plate 12 is provided on the top of the concentration tank 1. The edge of the cover plate 12 can be connected to the concentration tank through limiting structures such as bolts and buckles. The cover plate 12 has dense ventilation holes, which can prevent external debris from falling into the concentration tank without affecting the operation of the concentration tank. The concentration tank 1 is used to store produced water from high-salinity gas fields and reaction liquid for the synthesis of calcium chloride.

[0029] The rotating assembly 2 is located inside the concentration tank 1. The stirring mechanism on the rotating assembly 2 is used to stir the liquid in the concentration tank 1. The stirring mechanism on the rotating assembly 2 includes a rotating shaft 21 located in the middle of the inner cavity of the concentration tank 1. A connecting groove 22 is provided at the bottom end of the rotating shaft 21. The connecting groove 22 is connected to the output shaft of the reduction motor 11, so that the rotating shaft 21 can rotate with the drive of the reduction motor 11. At the same time, the rotating assembly 2 can be easily disassembled, cleaned and replaced. Multiple movable plates 23 arranged in a ring array are fixed on the outside of the rotating shaft 21 for stirring the liquid in the concentration tank 1. Multiple vertically distributed nozzles 24 with equal spacing are fixed at the ends of the movable plates 23 for spraying cleaning liquid onto the inner wall of the concentration tank 1. Multiple dovetail grooves 231 with equal spacing are provided on both sides of the ends of the movable plates 23. The dovetail grooves 231 on both sides of the movable plates 23 are staggered.

[0030] The connecting structure inside the rotating assembly 2 can spray the cleaning fluid onto the inner wall of the concentration tank 1 for quick cleaning of the concentration tank 1. The connecting structure on the rotating assembly 2 includes a connecting groove opened at the upper end of the rotating shaft 21 and a liquid channel opened on the movable plate 23. The two ends of the liquid channel are connected to the connecting groove and the nozzle 24 respectively. The liquid channel is not shown in the figure. It is opened inside the movable plate 23 and connected to the connecting groove on the rotating shaft 21.

[0031] The top end of the rotating shaft 21 is provided with a threaded groove 25. A fixing plate 26 is fixed to the outer side of the upper end of the rotating shaft 21. A first spring 27 is connected to the upper surface of the fixing plate 26 and sleeved on the outer side of the rotating shaft 21. A sealing plate 28 is connected to the top of the first spring 27 for sealing by the elastic force of the first spring 27. The sealing plate 28 is in contact with the lower surface of the cover plate 12 and is sealed by the rubber gasket on the sealing plate 28.

[0032] The connecting component 3 is located on the top of the rotating assembly 2 and is used to connect the connecting structure on the rotating assembly 2 with the external cleaning fluid pipeline, so as to facilitate the cleaning of the concentration tank 1. The connecting component 3 includes a threaded sleeve 31 that is sleeved on the outside of the threaded groove 25. A connecting flange 32 is fixed at the top of the threaded sleeve 31. The connecting flange 32 is connected to the external cleaning fluid pipeline by bolts. The connecting component 3 is installed on the rotating shaft 21 after the cover plate 12 is put on, without affecting the installation of the cover plate 12.

[0033] The second embodiment differs from the first embodiment in that the cleaning component 4 is located at the stirring mechanism of the rotating assembly 2 and is used to scrape and clean the inner wall of the concentration tank 1. The cleaning component 4 includes a first scraper 41 and a second scraper 42 located on both sides of the end of the movable plate 23. The first scraper 41 and the second scraper 42 are both in contact with the inner wall of the concentration tank through inclined surfaces, which plays a good scraping role. A plurality of dovetail sliders 43 are fixed on one side of the first scraper 41 and the second scraper 42. The dovetail sliders 43 on the first scraper 41 and the second scraper 42 are staggered and located in the dovetail groove 231 for guiding and limiting the first scraper 41 and the second scraper 42. The dovetail sliders 43 are connected to the inner wall of one end of the dovetail groove 231 through the second spring 44.

[0034] Before the device is put into operation, the connecting groove at the bottom of the rotating shaft 21 is connected to the output shaft of the geared motor 11. During this process, the first scraper 41 and the second scraper 42 on the cleaning component 4 are retracted to prevent the setting of the cleaning component 4 from blocking the rotating component 2 from being placed into the concentration tank. After the rotating shaft 21 is installed, the first scraper 41 and the second scraper 42 are attached to the inner wall of the concentration tank under the action of the second spring 44. Then, the liquid for preparing industrial calcium chloride is introduced into the concentration tank. Then, the cover plate 12 is placed on the top of the concentration tank until the top of the rotating shaft 21 passes through the through hole in the middle of the cover plate 12. At this time, the lower surface of the cover plate 12 is attached to the sealing plate 28 and drives the sealing plate 28 to squeeze the first spring 27, so that the sealing plate 28 plays a sealing role. Then, the screw sleeve 31 is connected to the screw groove 25 at the top of the rotating shaft 21 through the internal and external threads. Finally, the external cleaning liquid pipeline is connected to the connecting flange 32 through bolts.

[0035] During the concentration process, the geared motor 11 is started, which drives the movable plate 23 to rotate, stirring the liquid in the concentration tank and improving work efficiency. After the device finishes working, the inner wall of the concentration tank needs to be cleaned. At this time, the geared motor 11 is started, which drives the movable plate 23 to rotate. The first scraper 41 and the second scraper 42 on the movable plate 23 scrape and clean the inner wall of the concentration tank. At the same time, the cleaning liquid is sprayed from the nozzle 24 onto the inner wall of the concentration tank through the external cleaning liquid pipe, the connecting groove in the rotating shaft 21, and the liquid channel on the movable plate 23, so that the two scrapers can clean the concentration tank.
