The utility model relates to a sand removing device adaptive to thickened oil cold production, which is characterized by comprising a tank. The tank is partitioned into a sand settling area and an overflow area by a partition plate in the tank, a fluid passage is reserved between the partition plate and an upper cavity of the tank, an oil inlet is arranged at the tank head of the sand settling area, an oil outlet is arranged at the tail of the overflowing area, the partition plate is higher than the oil outlet, an air outlet is arranged on the tank right above the partition plate, a plurality of inclined plates arranged in the sand settling area are arranged at intervals in the length direction of the tank and arranged in an upper layer and a lower layer radially, the bottom of the tank is in the structure of a 'V'-shaped inclined groove, and the bottom of the 'V'-shaped inclined groove is provided with sand outlets right pointing to the lower ends of the corresponding inclined plates. The sand removing device adaptive to thickened oil cold production is capable of avoiding sand settling, and removing rate of sand grains in thickened oil with diameters above 75 micrometers can be up to 95%.
