Description

Technical Field

[0001] The utility model relates to the field of drying equipment, in particular to a liquid filtering spray drying equipment for preparing hydrotalcite. Background Art

[0002] Aluminum carbonate is mainly used to neutralize excessive gastric acid, protect gastric mucosa, adsorb and bind pepsin, and bind bile acid, thereby preventing these substances from damaging the gastric mucosa. Spray drying is a method of applying systematic technology to material drying. Through mechanical action, the material to be dried is dispersed into very fine mist-like particles, which come into contact with hot air, and most of the moisture is removed instantly, so that the solid matter in the material is dried into powder. However, the spray drying equipment currently used often causes particles to adhere to the bottom of the dryer when discharging, which reduces the collection rate of finished products and easily causes pollution.

[0003] The existing patent announcement number CN220588953U proposes a high-efficiency spray drying equipment, in which the blower is started to allow air to enter the hot air inlet pipe for heating, and then transported to the drying tower, and then the No. 1 motor is turned on, and the raw materials are poured into the atomizer through the liquid inlet pipe, and atomized and spirally sprayed out, so that the hot air sprayed from the hot air inlet pipe dries it, and at the same time, the No. 2 motor is started to rotate forward, driving the gear at the upper end of the rotating shaft to rotate, thereby driving the rotating sleeve to rotate, thereby driving the knocking block fixed at its lower end to rotate back and forth in the vibration chamber, thereby hitting the surface of the vibration block to prevent the dried finished particles from adhering to its bottom, but the produced material is easy to stick to the inner wall and bottom of the main tower, which is difficult to remove. Long-term accumulation has a great impact on the production efficiency and service life of the spray drying equipment. Utility Model Content

A cleaning component for cleaning the inner wall of the main tower 100 is disposed on the rotating shaft 402, and a scraping component for scraping the bottom of the main tower 100 to prevent it from sinking to the bottom is mounted at the bottom of the rotating shaft 402.

[0025] The first mounting frame 200 facilitates the installation of the feed pipe 201, the output end of the feed pipe 201 is located directly above the hopper 102, the feed pipe 201 is used to assist in feeding, and a filtering device is provided inside the feed pipe 201, and the feed liquid entering the spray drying equipment is filtered through the feed pipe 201, so as to improve the purity of the final aluminum carbonate magnesium powder. By starting the blower 301, the air enters the air inlet pipe 300 for heating, and then is transported to the main tower 100, and then the rotary drive 401 is turned on, and the raw materials are poured into the hopper 102 through the feed pipe 201, and are atomized and spirally sprayed out, and the completed materials are discharged from the discharge pipe 103, and a control valve is provided on the discharge pipe 103 to control whether the material is discharged.

[0026] See also Figure 3-Figure 5 As shown, the cleaning components are provided in three groups, each group of cleaning components includes three buffer rods 500 installed in an array on the rotating shaft 402, the buffer rods 500 are installed on the rotating shaft 402 through a mounting mechanism, a protective sleeve 501 is provided on the outer side of the buffer rods 500, and the ends of the three buffer rods 500 are connected to the cleaning plate 502.

[0027] The rotary driver 401 is started to drive the plurality of buffer rods 500 disposed on the rotating shaft 402 to rotate, and the buffer rods 500 press the cleaning plate 502 so that the cleaning plate 502 is close to the inner wall of the main tower 100 for cleaning.

At the same time, the connecting rod 504 installed at the bottom of the rotating shaft 402 rotates together, so that the scraper 505 rotates and rubs against the bottom of the main tower 100 to scrape and clean the material.

[0030] See also Figure 6 and Figure 7 As shown, the mounting mechanism includes a plurality of mounting holes 600 opened on the rotating shaft 402, and slots 601 are opened on both sides of the inner wall of the mounting holes 600, and mounting slots 602 are symmetrically opened on both sides of the buffer rod 500.
