[0002] Biochemical engineering is an interdisciplinary subject consisting of biology, chemistry, engineering and other disciplines. It studies the basic theories and engineering technologies in processes involving organisms or biologically active substances. It is an important branch of the first-level discipline "Chemical Engineering and Technology" and a key second-level discipline, and plays a key role in the industrialization of biotechnology.

[0003] At present, in the methyl chloride production process, hydrochloric acid is required to be used for separation to produce hydrogen chloride. This process uses calcium chloride as a boiling agent to deeply separate the hydrochloric acid and separate the hydrogen chloride. In the production process, the hydrochloric acid temperature is often too low. After mixing with the concentrated calcium chloride solution, calcium chloride crystals are more likely to precipitate in the pipeline, blocking the hydrochloric acid pipeline. With the blockage of the pipeline, the hydrochloric acid cannot be discharged and mixed with the concentrated calcium chloride solution, which in turn affects the production of hydrogen chloride and affects the production efficiency. Summary of the invention

[0004] The utility model aims to provide a hydrochloric acid desorption and corrosion resistance device to solve the problem of easy formation of crystals and clogging of hydrochloric acid pipelines proposed in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hydrochloric acid desorption and corrosion resistance device, comprising a pipe body, the top of the pipe body is connected to a feed pipe, a feed valve is fixedly installed on the top of the feed pipe, a mounting frame is fixedly installed on the bottom of the pipe body, a sealing gasket is fixedly installed on the bottom of the mounting frame, and a discharge groove is opened at the bottom of the inner cavity of the pipe body;

[0006] An anti-blocking mechanism is arranged on the left side of the tube body, and the anti-blocking mechanism includes a first motor, a second motor, a second U-shaped plate, a steel brush plate, a scraper and a corrosion-resistant coating. The first motor is fixedly installed on the left side of the tube body, and a bidirectional screw is fixedly connected to the output end of the second motor. Screw blocks are threadedly connected to the left and right sides of the surface of the bidirectional screw, and first U-shaped plates are fixedly installed on the upper and lower sides of the two screw blocks. Connecting rods are movably connected to the inner sides of the four first U-shaped plates. A blanking box is arranged at the bottom of the tube body, and mounting blocks are fixedly installed on the front and rear sides of the blanking box, and fixing bolts are threadedly connected to the bottoms of the ten mounting blocks.

[0007] Preferably, a box is fixedly mounted on the output end of the first motor, and a second motor is fixedly mounted on the left side of the inner cavity of the box.

[0008] Preferably, a scraper is movably connected to the bottom of the outer sides of the four connecting rods, and the outer sides of the scraper fit into the inner cavity of the tube body.

[0009] Preferably, the steel brush plate is fixedly mounted on the top of the outer sides of the four second U-shaped plates, and a hard steel brush is fixedly mounted on the top of each of the steel brush plates.

[0010] Preferably, screw grooves are provided on both the front and rear sides of the bottom of the mounting frame, and the tops of the ten fixing bolts are threadedly connected to the inner cavities of the ten screw grooves.

[0011] Preferably, limit rods are fixedly installed on both upper and lower sides of the right side of the box body, and the inner surfaces of the two screw blocks are slidably connected to the surfaces of the two limit rods.

[0013] Compared with the related art, the rotary shaft masterbatch metering device provided by the utility model has the following beneficial effects:

[0014] 1. The utility model sets an anti-blocking mechanism. Through the output of the second motor, the first U-shaped plate hit by the screw block moves inward along the surface of the bidirectional screw. At this time, the connecting rod flips outward and pushes the steel brush plate, the hard steel brush and the scraper to move outward, so that the scraper and the hard steel brush are in contact with the inner wall of the tube body. Then, through the output of the first motor, the box body and the second motor rotate, and drive the hard steel brush and the scraper to move in a circle in the inner cavity of the tube body, so as to scrape off the crystals bonded to the inner wall of the tube body to prevent them from sticking to the inner wall of the tube body and affecting the feeding of hydrochloric acid.

[0015] 2. The utility model can drive the steel brush plate, the hard steel brush and the scraper to move in a circle along the inner wall of the tube body by setting a box body, so as to scrape off the crystals in the inner wall of the tube body. By setting the scraper, the crystals in the inner wall of the tube body can be scraped off, so that they fall off from the inner wall of the tube body, and the crystals in the inner wall of the tube body can be scraped off. By setting the hard steel brush, the crystals scraped off by the steel brush plate can be conveniently cleaned, so that they fall into the inner cavity of the blanking box through the discharge groove. By setting the fixing bolts and screw grooves, the blanking box can be disassembled, which is convenient for the scraped crystals. Collect and clean to avoid crystal accumulation in the inner cavity of the pipe body, affecting the normal transportation function of the pipe body for hydrochloric acid. By setting a limit rod, the movement of the screw block can be limited to prevent the screw block from rotating synchronously with the bidirectional screw, resulting in the hard steel brush and scraper being unable to fit the inner wall of the pipe body, making it impossible to remove the crystals in the inner cavity of the pipe body. By setting a corrosion-resistant coating, due to the particularity of its material, it can effectively prevent the parts of the anti-blocking mechanism in the pipe body from being corroded by hydrochloric acid, thereby avoiding damage to the parts due to the erosion of hydrochloric acid, and then reducing the service life of the equipment.

[0028] See also Figure 3 The bottom of the outer sides of the four connecting rods 207 is movably connected with a scraper 211 , and the outer side of the scraper 211 fits with the inner cavity of the tube body 1 .

At this time, the scraper 211 and the hard steel brush 210 cooperate with each other to scrape off the crystals adhered to the inner wall of the tube body 1, and the scraped crystals fall into the blanking box 213 through the discharge chute 7 due to the influence of their own gravity. When the equipment stops working, the blanking box 213 is released from the mounting frame 5 by rotating the fixing bolt 215, and the blanking box 213 is moved downward to facilitate the cleaning of the crystals in the inner cavity of the blanking box 213.
