scraper structure of mother liquor dryer

Abstract

This utility model relates to a scraper structure for a mother liquor drying machine, comprising a distillation tank and a discharge pipe. A feed hopper is fixedly connected to the right side of the distillation tank. A discharge mechanism, located inside the distillation tank, guides the residue. A cleaning mechanism, also located inside the distillation tank, cleans the inner wall of the tank. The cleaning mechanism includes several limiting frames, with a movable plate slidably connected to the outer surface of each frame. A limiting rod is slidably connected inside each frame, and a scraper is fixedly connected to the side of the limiting rod away from the connecting sleeve. The movable plate and limiting rod drive the scraper, ensuring it remains in close contact with the tank wall, effectively scraping off scale buildup. This not only reduces the impact of scale buildup on the tank's stress but also extends the tank's service life and significantly reduces cleaning difficulty.

Description

Technical Field

[0001] This utility model belongs to the field of distillation tank maintenance technology, and in particular relates to the scraper structure of a mother liquor drying machine. Background Technology

[0002] Mother liquor is a high-concentration liquid waste remaining after solid-liquid separation in industrial production. It usually contains a large amount of soluble salts, organic matter, heavy metals or other pollutants. Direct discharge or disposal poses environmental risks and may cause waste of resources.

[0003] The core of the mother liquor drying process is to remove water from the mother liquor through physical or thermochemical methods, converting it into solid dry residue, thereby achieving volume reduction, harmlessness, and resource utilization. It is a key link in the end-of-life disposal or resource recovery of mother liquor. However, existing mother liquor drying machines are prone to forming scale on the tank wall during the drying process. The formation of scale causes the tank wall to become unbalanced, and long-term adhesion can also lead to problems such as cracks in the tank body. This not only increases the difficulty of cleaning but also reduces the service life of the tank body. To address this, we have proposed a scraper structure for the mother liquor drying machine. Utility Model Content

[0004] The purpose of this invention is to provide a scraper structure for a mother liquor dryer. By setting a cleaning mechanism, specifically a moving plate and a limiting rod driving the scraper, it is kept in close contact with the tank wall of the distillation tank, scraping off the scale adhering to the tank wall. This timely scraping off of scale not only reduces the impact of scale on the tank body's stress but also extends the tank's service life to some extent, greatly reducing the difficulty of cleaning. This solves the problem that existing mother liquor dryers easily form scale on the tank wall during the drying process of mother liquor. The formation of scale causes stress imbalance on the tank wall, and long-term adhesion can lead to cracks in the tank body, which not only increases the difficulty of cleaning but also reduces the service life of the tank.

A limiting rod 312 is slidably connected inside the limiting frame 311, and a scraper 313 is fixedly connected to the side of the limiting rod 312 away from the connecting sleeve 323; a motor 13 is fixedly connected to the right side of the distillation tank 1; the limiting rod 312 provides a support base for the scraper 313; the limiting frame 311 limits the limiting rod 312; and the discharge mechanism 2 includes two cleaning rings 23, which are used to clean the inner walls on both sides of the distillation tank 1. The cleaning mechanism 3 includes a scraping component 31 installed inside the distillation tank 1, which scrapes away scale on the tank wall of the distillation tank 1; and a linkage component 32 installed inside the distillation tank 1, the internal structure of which is linked with the internal structure of the scraping component 31; the linkage component 32 provides a supporting foundation for the internal structure of the scraping component 31. The discharge mechanism 2 includes three connecting rods 22, and two cleaning rings 23 are fixedly connected to the left and right sides of the connecting rods 22 on opposite sides. Several arc-shaped guide plates 21 are fixedly connected to the outer surface of the connecting rods 22; the connecting rods 22 provide a supporting foundation for the arc-shaped guide plates 21. The rotating shaft 321 also drives the cleaning rings 23 to rotate, and the cleaning rings 23 clean the scale on both ends of the distillation tank 1. The arc-shaped guide plates 21 rotate through the connecting rods 22, and the rotation of the arc-shaped guide plates 21 transports the residue scraped off by the scraper 313 into the discharge pipe 11 and discharges it.

[0020] The scraping assembly 31 includes a hinge frame 315 mounted on the side of the movable plate 314 away from the limiting rod 312. The side of the movable plate 314 near the limiting rod 312 is fixedly connected to the side of the limiting rod 312 away from the scraper 313. The movable plate 314 provides a support base for the limiting rod 312. The scraper 313 is triangularly shaped. The linkage assembly 32 includes a rotating shaft 321. The right side of the rotating shaft 321 is fixedly connected to the left output end of the motor 13 via a coupling. Two connecting sleeves 323 are fixedly connected to the outer surface of the rotating shaft 321. The outer surface of the connecting sleeves 323 is fixedly connected to the side of the limiting frame 311 near the rotating shaft 321. The rotating shaft 321 provides a support base for the connecting sleeves 323. A sliding rod 322 is fixedly connected inside the limiting frame 311. The sliding connection has two hinge frames 326.

[0021] One specific application of this embodiment is as follows: The evaporated mother liquor enters the thickener, is pumped into the raw water metering tank by the raw water pump, and the bottom of the tank is connected to the equipment inlet via a pipe. After the equipment is turned on, the vacuum pump starts running, and the pneumatic valves open to allow liquid to enter according to the set operating cycle. After the liquid enters the set amount, the waste liquid inlet pneumatic valve closes and the steam valve opens to start distillation. The distillation tank 1 is under reduced pressure, and the temperature of the waste liquid in the tank quickly rises to boiling. The water in the waste liquid begins to evaporate, and the water vapor enters the condenser through the steam filter and is condensed into liquid recycled water. After being metered, the water is discharged into the recycled water metering tank and pumped to the secondary treatment equipment by the recycled water pump. After the equipment enters the distillation process, the motor 13 starts with a delay. The internal structure of the cleaning mechanism 3 stirs the waste liquid in the tank, which helps to ensure uniform heating of the waste liquid and avoids scaling on the inner wall of the tank during the distillation process. After the equipment finishes distillation, the steam valve is closed, and the steam bypass valve and atmospheric vent valve are opened to release pressure. After the pressure is released, the residue discharge valve is opened. The cylinder at the front cover begins to discharge slag. The starting motor 13 drives the rotating shaft 321 to rotate, which in turn drives the connecting sleeve 323 to rotate. The connecting sleeve 323 then drives the limiting frame 311 to rotate. The limiting frame 311 and the moving plate 314 work together to drive the limiting rod 312 to rotate. The limiting rod 312 then drives the scraper 313 to rotate. Due to the connecting rod 325, the second hinge frame 326 is constantly compressed. The second hinge frame 326, through the connecting rod 325, drives the first hinge frame 315 to... The movable hinge frame 315 drives the scraper 313 through the moving plate 314 and the limiting rod 312, keeping it in close contact with the wall of the distillation tank 1 and scraping off the scale attached to the tank wall. At the same time, the rotating shaft 321 also drives the cleaning ring 23 to rotate, which cleans the scale on both ends of the distillation tank 1 and drives the arc-shaped guide plate 21 to rotate through the connecting rod 22. The rotation of the arc-shaped guide plate 21 will transport the residue scraped off by the scraper 313 into the discharge pipe 11 and discharge it.
