The utility model relates to the technical field of tetrahydrofuran, and discloses a storage tank for preparing crude tetrahydrofuran, which comprises a base, an outer cylinder mounted at the top end of the base, an inner cylinder arranged in the outer cylinder, a liquid level meter mounted in the inner cylinder, a vacuum cavity arranged outside the inner cylinder, a feed pipe mounted at one end of the outer cylinder, and a first valve mounted at one end of the feed pipe. One end of the first valve is connected with the filter, and one end of the filter is connected with the flange ring. According to the storage tank for preparing crude tetrahydrofuran, convective heat transfer of gas between the outer cylinder and the inner cylinder is reduced through the vacuum cavity, so that the inner cylinder is kept in a stable temperature state, tetrahydrofuran liquid is in a stable state, the outer cylinder is made of an anti-explosion material, a flame-retardant layer is arranged on the inner surface of the outer cyl
