Description

Technical Field

[0001] The present invention belongs to the technical field of sheet desalination operation in the process of salt production, and particularly relates to a sheet desalination device for the salt industry. Background Art

[0002] Seawater salt production is an all - open - air operation, and high - concentration brine is the key raw material for salt production. The high - concentration brine is obtained by gradually concentrating low - concentration seawater relying on solar energy and wind energy. To reduce the dilution of high - concentration brine by rainfall, it is necessary to timely drain the fresh water in the evaporation area (the area before the brine enters the crystallization pond for salt production) and the crystallization pond (the area for producing salt from saturated brine) after rainfall (this process is called "sheet desalination"). Currently, there are mainly three sheet desalination methods.

[0003] I. Man - made sheet - mouth sheet desalination. This sheet desalination method is mainly applied in the evaporation area. That is, an earth embankment is manually dug in the downwind direction of the light - circle or heavy - circle evaporation pond to make a sheet - mouth, and the sheet - mouth is made by pressing a salt film with red bricks. The depth and width of the sheet - mouth need to be determined according to the amount of rainfall, and it is appropriate to reach the mixing gap between fresh water and brine. The above - mentioned sheet desalination method has a large labor intensity, low efficiency, and high requirements for the production of the sheet - mouth. Once the sheet - mouth is not tightly covered or the inspection is not timely, it is easy to cause the risk of "a small stream breaking a big dam", resulting in the loss of high - concentration brine and seriously affecting salt production.

[0004] II. Sheet - desalination gate sheet desalination. This sheet desalination method is mainly applied in the formed - brine area (saturated brine is formed - brine) of the evaporation area, and the brine depth generally reaches about 2 meters. The sheet - desalination gate is generally made of wood, and is squeezed by the earth embankments on both sides. When the water pressure is too high, a concrete retaining wall must be used for fixation. The sheet - desalination gate is a double - core gate plate. The inner gate - plate sheet - desalination part is made of small wooden blocks with a thickness of 3 - 5 cm spliced together, and the outer side is a whole liftable gate plate. During sheet desalination, while lifting the whole outer gate plate, small wooden blocks blocked by the inner gate - plate are removed one by one according to the required sheet - desalination depth to achieve the purpose of sheet desalination. This sheet - desalination gate is not easy to fix, and the gate frame is easily deformed when the water pressure is too high, making it difficult to operate. Moreover, the small wooden blocks for sheet desalination have fixed sizes, which is inconvenient for operation and cannot accurately control the sheet - desalination depth according to actual needs; there are gaps between the small wooden blocks, resulting in brine leakage.

[0005] 3. Funnel gate thinning. This thinning method is mainly used in the crystallization pool. The rise and fall of the funnel gate is controlled by a 0.5T hand-cranked shutter. There is a water inlet on one side of the crystallization pool of the funnel gate. According to the amount of rainfall and wind direction, the height of the funnel gate is controlled to slice the rainwater collected by the salt membrane. The funnel gate and the diversion pipe are softly connected with nylon bags and clamps to realize the rise and fall of the shutter. If the clamp at the soft connection is corroded by brine for a long time or is not checked in time, it is easy to cause brine leakage, lose a pool of saturated brine, and cause serious production losses. In addition, the working space of the funnel gate needs to be built with concrete. Due to the inconvenience of walking on the road under the beach and the inconvenience of using large-scale mechanical equipment, building materials can only be transported manually, which invisibly increases the cost of masonry and maintenance of the stone wall of the funnel gate, and the construction period is long, which has a great impact on production.

[0006] The above three salt thinning methods have the disadvantages of inconvenient operation, high labor intensity, poor effect, high maintenance cost, and great impact on production, and are not suitable for the development needs of mechanization and intelligence of modern salt production industry.

[0046] For those of ordinary skill in the art, without creative efforts, other related drawings can be obtained based on the above drawings. Detailed implementation manners

[0047] In order to enable those skilled in the art of this technology to better understand the technical solution of the present invention, the technical solution of the sheet desalination device for the salt production industry of the present invention will be further described below in conjunction with the drawings in the specification and through specific implementation manners.

[0048] As Figures 1 to 8 shown, a sheet desalination device for the salt-making industry includes a frame mechanism 1, a diversion pipe 2, a tee 3, a water collection nozzle 4, and a driving mechanism 5.

[0049] The frame mechanism 1 is a hollow cuboid structure with one end open, composed of a back plate 11, a bottom plate 12, a top plate 14, and two side plates 13. An equipment rack 15 is arranged above the top plate 14; through holes 16 are formed on the back plate 11; the longitudinal section of the side plate 13 is a right trapezoid, and the right-angle side is fixedly connected to the back plate 11; the equipment rack 15 is composed of two layers of I-beams, with two I-beams arranged in each layer, and the two layers of I-beams are arranged in a cross shape. The frame mechanism 1 is formed by membrane pressing of fiberglass material. The frame mechanism 1 replaces the concrete stone wall of the conventional sheet desalination device, providing an operating space for the water collection nozzle mechanism 4. When the device is not working, the water collection nozzle mechanism is stored in the operating space, located below the salt film slideway, without affecting the plastic covering operation.

[0050] The diversion pipe 2 and the tee 3 are respectively arranged on both sides of the back plate 11 of the frame mechanism 1, and the diversion pipe 2 is communicated with the vertical shaft pipe of the tee 3 through the through hole 16 of the back plate 11; the back plate 11 is connected to the diversion pipe 2 and the tee 3 through a plurality of evenly distributed nylon bolts. The diversion pipe 2 is a splicing pipe structure composed of multiple joints, and the length of the diversion pipe 2 can be adjusted according to actual needs.

[0051] The cross-section of the water collection nozzle mechanism 4 is concave, and water outlets 42 are formed on both side walls of the concave part. One end far from the concave part forms the water collection nozzle of the water collection nozzle mechanism 4, that is, the water inlet; the water collection nozzle mechanism 4 gradually increases in longitudinal section from one side of the water collection nozzle lip 41 to the concave part; a convex ring 43 is formed on the outer wall of the water collection nozzle mechanism 4 near one end of the water collection nozzle lip 41. The two ends of the transverse shaft pipe 31 of the tee 3 are respectively connected to the two water outlets 42 of the water collection nozzle mechanism 4, and a sealing ring 6 is arranged between the transverse shaft pipe 31 and the water outlet 42. A clamping groove is arranged on the inner wall of the water outlet 42, and the sealing ring 6 is arranged in the clamping groove to realize effective limitation of the sealing ring 6. The water collection nozzle mechanism 4 is composed of two symmetrically structured water collection nozzle units, and the edges of the two water collection nozzle units are fastened by a closing fastening bolt to form a complete body.

[0052] The driving mechanism 5 includes a worm and gear hoist 51 arranged on the top of the top plate 14 through the equipment rack 15 and a rack 52 meshing with the gear of the worm and gear hoist 51. The bottom end of the rack 52 is connected to the water collection nozzle mechanism 4 through a worm driving pin seat 53; the worm driving pin seat 53 is fixed on the outer wall of the water collection nozzle mechanism 4.

[0053] The sheet desalination device for the salt-making industry further includes an intelligent control mechanism. The intelligent control mechanism includes a brine density sensor 7 and a brine level sensor 8 provided on the bottom surface of the top plate 14, and a remote control module. The remote control module is a PLC or a single-chip microcomputer, and the remote control module is electrically connected to the brine density sensor 7, the brine level sensor 8, and the worm gear actuator 51.

[0054] The connecting parts between the remaining components of the device are also made of materials resistant to saline-alkali corrosion.

[0055] The working principle of the present invention:

[0056] The present invention designs a fiberglass prefabricated panel whose strength can replace a concrete wall, and is fixed by nylon bolts to form a working space for the sheet desalination device; designs a rotatable funnel-shaped water receiving nozzle mechanism, which can drive a rack through a servo motor to adjust the rotation angle of the water receiving nozzle mechanism, and use different angles to reach the position to be sheet desalinated or the corresponding critical point. Utilizing the different specific gravities of brine and fresh water, when the critical point is the stratification point of brine and fresh water, fresh water is sheeted out from the salt film or the brine pond.

[0057] The working process of the present invention:

[0058] Installation of the device:

[0059] During installation, earth dams need to be made as enclosures at the sheet opening positions (the four corner positions of the pool). Grooves are cut on the earth dams of the evaporation pond or the crystallization pond according to the required installation depth, and the fiberglass frame is buried in the earth dam with the open end facing the inside of the pool. The burial depth is flush with the bottom of the pool, which can be used for sheet desalination and also for "draining the pool" (the process of draining the brine in the evaporation pond or the crystallization pond is commonly called "draining the pool"). Then backfill with plain soil and tamp it firmly. After ensuring no leakage, remove the enclosing dam, and the installation is completed.

[0060] Use of the device:

[0061] (1) Sheet desalination in the evaporation area

[0062] According to the signals collected by the brine density sensor and the level sensor, after data analysis and transmission by the remote control module, the signals are fed back to the operation software interface. According to the production process requirements, after determining the depth of sheet desalination required, the remote control module controls the worm gear actuator to adjust the position of the water receiving nozzle mechanism, that is, the inclination angle, so that the lip of the water receiving nozzle reaches the critical point and then sheet desalination is carried out. Fresh water enters the diversion pipe through the water outlet, and then enters the desalination system.

[0063] (2) Sheet desalination in the crystallization pond

[0064] The salt film sheet opening can be sewn with an elastic band. When the brine is diluted, the prepared salt film sheet opening needs to be manually sleeved on the convex ring, and the elastic band is located on the side of the convex ring close to the water inlet. The salt film sheet opening completely wraps the lips of the water collecting nozzle, and the convex ring can effectively fix the salt film sheet opening and prevent the mixing of fresh water and brine. The position of the water collecting nozzle mechanism is adjusted by controlling the worm and worm gear opener with a radio remote control. When it reaches a position 2 cm to 5 cm below the salt film sheet opening, the brine is diluted. Fresh water enters the diversion pipe through the water inlet and then enters the fresh water drainage system. Since the operations such as the production of the salt film sheet opening and sleeving the salt film sheet opening during the brine dilution in the crystallization pond still need to be carried out manually and cannot be remotely controlled for the time being, the brine dilution in the crystallization pond is realized through a radio remote control to reduce the cost investment.

[0065] (3) Drainage "draining into the pond"

[0066] When "draining into the pond" in the evaporation area, according to the parameters set by the liquid level sensor, the depth of the water collecting nozzle mechanism is adjusted by driving the rack with the worm and worm gear opener through the remote control module to perform the "drainage draining into the pond" work. In the crystallization pond, this work is carried out by manually operating the remote control.

[0067] The application of remote control and radio remote control technology is already mature at the present stage and will not be elaborated here.

[0068] The present invention uses fiberglass plates resistant to saline-alkali corrosion to replace concrete stone walls, reducing the installation and maintenance costs, improving the operation efficiency, and reducing the impact of construction on salt production; the brine dilution gate and the diversion pipe form an integral whole, avoiding the occurrence of brine leakage; the installation of remote control and radio remote control operation modules reduces manual operation and alleviates the labor load, laying a solid foundation for the subsequent development towards intelligent salt production.
