The invention relates to a preparation method of tobacco particles improved by endogenous scent substances. The method comprises steps as follows: concentration, scent preparation, spraying, scent improvement and the like. The scent of tobacco particles prepared with the method is harmonious with and similar to that of tobacco, and the tobacco particles endow tobacco products with unique and mellow scent. The tobacco particles produced with the method can effectively reduce release of tar and CO, can reduce tar and harm, improves safety of tobacco products and can remarkably improve the sensory effect during smoke without reducing the concentration of smoke.

The invention discloses an organic fertilizer collecting device. The organic fertilizer collecting device comprises a urine pool fixedly arranged on a wall body, a urethra tube connected with a urine collecting cylinder and a connecting tube connected with a dirt discharge system; a placing cavity is arranged in the ground surface; a rotating frame is rotatably arranged at the right lower end of the placing cavity by using a rotating pin shaft; a first through connecting hole is formed in the left end of the rotating frame; a collecting device is fixedly arranged at the lower end of the placing cavity; the collecting device comprises a first sleeve shell; a first cavity is formed in the first sleeve shell; a first barrier plate is fixedly arranged in the first cavity; the first barrier plate separates the first cavity into a first upper cavity and a first lower cavity; a first sliding block is arranged in the first lower cavity in an up-and-down sliding mode; a first top arm is fixedly arranged at the middle end of the upper end surface of the first sliding block; the upper end of the first top arm penetrates through the first barrier plate and the first sleeve shell and penetrates into the placing cavity; a second through connecting hole for connecting the first upper cavity and the first lower cavity is formed in the first barrier plate in a bilateral symmetry mode.

Relating to the field of titanium dioxide production, the invention discloses a method and equipment for production of titanium dioxide by a sulphate process. Specifically, the method includes the steps of acidolysis, leaching, crystallization and crystal separation on ilmenite concentrate powder, and the method also includes the steps of mixing the centrifugal mother liquid generated in a crystal separation process with process water in a weight ratio of 1:(1-2.5) to form a centrifugal mother liquid diluent, and using the centrifugal mother liquid diluent as at least part of leaching water to be reused in the leaching step. The process water is one or more of desalted water, clean circulating water and dirty circulating water. According to the method, the centrifugal mother liquid and the process water are mixed in proportion, at the same time of avoiding hydrolysis of titanium in the centrifugal mother liquid, the centrifugal mother liquid is diluted, so that the problem of blocking a pipeline valve and transfer pump can be effectively improved. Also, by reusing the centrifugal mother liquid diluents in the leaching step, the titanium in the centrifugal mother liquid can be recovered, and also increase of the concentration cost is avoided.
