Description

Technical Field

[0001] This utility model relates to a brine concentration device, belonging to the field of brine concentration technology. Background Technology

[0002] my country's lithium resources in salt lakes are mainly concentrated in the Qinghai-Tibet Plateau region. The western region has a fragile environment and high environmental protection requirements, which limits the large-scale development of salt fields during the lithium extraction process. However, brine concentration is a crucial step in the lithium extraction process, and a stable supply of concentrated brine is the cornerstone of lithium extraction from salt lakes. Existing brine concentration methods typically employ the conventional sun-drying method, which involves constructing sun-drying ponds (salt flats) and using natural wind and sun to evaporate nearly 90% of the water in the ponds, thereby concentrating the brine. Relying on natural evaporation through sunlight has a long production cycle, low efficiency, and is heavily dependent on weather conditions, making it difficult to control brine production and meet production demands. Therefore, current technologies generally use concentration equipment to concentrate the brine.

[0003] Chinese utility model patent CN222389606U discloses a salt lake brine concentration device. The device comprises an electric heating rod, copper pipe, water pump, water outlet cover, fixed pipe, and impeller. During brine concentration, the water pump draws brine from the brine pool, filters it through a filter screen, and then sprays it onto the copper pipe through the water pipe and water outlet cover. The electric heating rod heats the copper pipe, and as the brine is sprayed onto the heated copper pipe, it continuously evaporates and concentrates the brine. A scraper removes brine crystals adhering to the outside of the copper pipe.

[0004] However, the above-mentioned patented solutions also have some inconveniences in practical applications. First, heating the brine with a vertically set copper rod results in poor heating effect because the brine and the copper rod cannot make good contact. In addition, the heating efficiency is low and cannot meet production needs. Second, the heated brine cannot dissipate heat sufficiently and cannot allow the water to dissipate completely, resulting in poor concentration effect.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This invention addresses the shortcomings of the prior art by providing a brine concentration device that enhances the contact effect between the brine and the heater, resulting in high heating efficiency; moreover, it significantly enhances the evaporation of water.

[0007] To solve the above technical problems, the present invention adopts the following technical solution:

[0008] A brine concentration device includes a shell, and a heater is provided at the upper part of the shell. The heater includes two circular end plates, and a plurality of heating rods are arranged axially between the two end plates.

[0009] A rotating shaft is installed on the left end plate of the heater, and a rotating sleeve is installed on the right end plate of the heater. The rotating shaft and the rotating sleeve are rotatably mounted on the side wall of the housing.

[0010] A second cylinder is also installed on the side wall of the housing. The piston rod of the second cylinder passes through the rotating sleeve, and a scraper is rotatably installed at the end of the piston rod. The scraper has an insertion hole at the position of the heating rod.

[0011] Furthermore, a transmission wheel is fixed to the end of the rotating shaft that extends outside the housing, and the transmission wheel is driven by a drive system.

[0012] Furthermore, the upper end of the housing is provided with a filter box, the top of the filter box is provided with a feed inlet, the bottom of the filter box is provided with a first filter screen, a first cylinder is fixed on one side of the filter box, the piston rod of the first cylinder extends into the filter box, and a push plate is fixed to the end of the piston rod of the first cylinder.

[0013] Furthermore, a cover plate is provided on the other side of the filter box, the upper end of the cover plate is hinged to the filter box, a push rod is provided on the inner side of the cover plate, and an impurity cylinder is provided below the end of the filter box where the cover plate is located.

[0014] Furthermore, a baffle plate is provided inside the shell on the lower side of the heater, and the baffle plate has a strip-shaped slit.

[0015] Furthermore, an intake fan and an exhaust fan are respectively provided on the two opposite side walls of the shell located on the upper side of the baffle plate.
