Description

Technical Field

[0001] The utility model belongs to the technical field of yellow phosphorus production and processing, in particular to a yellow phosphoric acid washing and purification device. Background Art

[0002] In the process of yellow phosphorus production, the yellow phosphorus raw material needs to be chlorinated, and after the chloride is obtained, it is subjected to vacuum distillation and hydrogen reduction, and then high-temperature smelting is performed to obtain the final yellow phosphorus product. Before the yellow phosphorus raw material is chlorinated, it needs to be pickled to remove impurities mixed in the raw material. Since it needs to contact strong acid during the reaction, the inside needs to be cleaned to avoid internal corrosion. Since some reaction tubes and covers are fixed by multiple sets of bolts, this makes it difficult for workers to disassemble and cannot clean the inside in time. In addition, a large amount of raw materials will be added at one time in industrial production, which causes some raw materials in the reaction tube to be unable to completely contact with the reactants, resulting in incomplete impurity removal and purification. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the utility model provides a yellow phosphoric acid washing and purification device, which solves the problem that the disassembly between the cover and the reaction tube is troublesome, resulting in difficulty in cleaning for staff, and solves the problem that a large amount of raw materials are added at one time, resulting in part of the raw materials in the reaction tube being unable to completely contact with the reactants, resulting in incomplete impurity removal and purification.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a yellow phosphoric acid washing and purification device, comprising an outer cylinder, a supporting leg is connected to the outer wall of the outer cylinder, an inner cylinder is connected to the inside of the outer cylinder, a heating pipe is arranged between the outer cylinder and the inner cylinder, an end cover is installed on the outer cylinder, a slot is opened on the top of the outer cylinder, a discharge port is connected to the bottom of the inner cylinder, a filling port is connected to one side of the top of the end cover, a connecting pipe is connected to the other side of the top of the end cover, a plug rod is connected to the bottom of the end cover, and a hollow plate is installed on the top of the end cover;

[0005] A pull rod is slidably connected inside the end cover, a mounting plate is connected above the end cover, a motor is mounted on the mounting plate, a rotating rod is connected to the motor output shaft, a stirring plate is connected to the rotating rod, a stirring blade is connected to one end of the rotating rod, a connecting frame is connected to the rotating rod, a scraper is connected between the two connecting frames, a push block is connected to one end of the pull rod, a fixing plate is connected to the pull rod, and a pull ring is connected to the pull rod.

[0006] As a further solution of the utility model: the scrapers are six in total and are symmetrical about the axis of the rotating rod, and the scrapers are of spiral design, and the stirring plate is provided with through holes.

[0007] As a further solution of the utility model: a first spring is connected inside the hollow plate, one end of the first spring is connected to a clamping block, the clamping block slides inside the hollow plate and is triangular in design, clamping grooves are provided on both sides of the fixed plate, and the clamping block is engaged with the clamping grooves.

[0008] As a further solution of the utility model: a sliding rod is slidably connected inside the insertion rod, one end of the sliding rod is connected to a connecting block, the connecting block is connected to a second spring, one end of the second spring is connected to the inner wall of the insertion rod, and sockets are opened on both sides of the slot, and the sliding rod is inserted into the sockets.

[0009] As a further solution of the utility model: the heating tube is spirally wound on the inner tube, a rubber pad is connected under the support leg, and an anti-slip pattern is provided under the rubber pad.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The yellow phosphoric acid washing and purification device is provided with a socket, a plug rod, a first spring, a card block, a card slot, a push block, a connecting block, a second spring and a sliding rod. The staff pushes the pull rod downward so that the push block can push the connecting block to move, prompting the connecting block to push the sliding rod to move and compressing the second spring so that the sliding rod is inserted into the socket, thereby fixing the end cover on the outer cylinder. While the pull rod moves downward, the fixed plate pushes the card block into the hollow plate to compress the first spring. When the fixed plate contacts the end cover, the first spring rebounds and pushes the card block to the card slot, thereby fixing the fixed plate and the pull rod to prevent the push block from moving. The staff pulls the pull rod through the pull ring to move the push block upward. At this time, the second spring rebounds to disengage the sliding rod from the socket, thereby removing the end cover. The operation is simple and convenient for the staff to observe and clean the inner cylinder and the stirring plate.

[0013] 2. The yellow phosphoric acid washing and purification device is provided with a heating tube, a motor, a rotating rod, a stirring plate, a stirring blade and a scraper. During the reaction, the heating tube will increase the temperature, thereby ensuring the reaction temperature in the inner cylinder, preventing the temperature from decreasing and causing the reaction rate to decrease. The motor can rotate the rotating rod, so that the stirring plate can stir the raw materials in the inner cylinder, so that the raw materials can be evenly contacted with the acid solution, thereby improving the effect and rate of the reaction. The stirring blades can stir the raw materials at the bottom of the inner cylinder to prevent the raw materials from being deposited. When the stirring plate and the stirring blades rotate, the scraper will also rotate together, thereby scraping the raw materials on the inner wall of the inner cylinder, preventing the yellow phosphorus from sticking to the inner wall and corroding the inner cylinder.

By plugging the insertion rod 10 into the socket 30, the end cover 5 can be fixed on the outer cylinder 1 to prevent the end cover 5 from loosening, thereby avoiding the leakage of raw materials and strong acid.

[0022] A hollow plate 11 is installed above the end cover 5, and a first spring 24 is connected inside the hollow plate 11. A clamping block 25 is connected to one end of the first spring 24. The clamping block 25 slides in the hollow plate 11 and is triangular in design. Clamping grooves 26 are provided on both sides of the fixed plate 22, and the clamping block 25 is engaged with the clamping grooves 26. The triangular design of the clamping block 25 enables the fixed plate 22 to flexibly and conveniently push the clamping block 25 to move, thereby facilitating the staff to fix the fixed plate 22 and the pull rod 12, and preventing the push block 21 from moving and causing the sliding rod 27 to disengage from the socket 30.

[0023] A pull rod 12 is slidably connected inside the end cover 5, a mounting plate 13 is connected above the end cover 5, a motor 14 is mounted on the mounting plate 13, a rotating rod 15 is connected to the output shaft of the motor 14, a stirring plate 16 is connected to the rotating rod 15, a stirring blade 17 is connected to one end of the rotating rod 15, a connecting frame 18 is connected to the rotating rod 15, a scraper 19 is connected between the two connecting frames 18, a total of six scrapers 19 are symmetrical about the axis of the rotating rod 15, and the scrapers 19 are of spiral design, a through hole 20 is opened on the stirring plate 16, and the yellow phosphorus adhering to the inner wall of the inner cylinder 3 is scraped off by multiple scrapers 19 to prevent the yellow phosphorus from corroding the inner wall of the inner cylinder 3.

[0024] A push block 21 is connected to one end of the pull rod 12, a fixed plate 22 is connected to the pull rod 12, a pull ring 23 is connected to the pull rod 12, the push block 21 is a frustum-shaped design, and the side of the connecting block 28 away from the second spring 29 is in close contact with the push block 21.
