[0002] Freeze concentration equipment is a kind of equipment used to concentrate solutions. It mainly uses freeze concentration method and utilizes the solid-liquid equilibrium relationship between dilute solution and ice below the freezing point under normal pressure to achieve it. Because it operates at low temperature and normal pressure, it has the advantages of preventing adverse chemical and biochemical changes and small loss of flavor, aroma and nutrition. Among them, freeze concentration technology is particularly suitable for concentrating heat-sensitive liquid foods, biopharmaceuticals, high-end beverages and Chinese herbal medicines that require retaining natural color, aroma and flavor. This low-energy consumption, high-quality product processing technology has huge development potential.

[0003] An ice scraper is generally provided in the freezing concentration equipment, which is used to scrape off the ice crystals on the surface of the refrigerant pipe in the cooling system so that the ice crystals fall into the solution, avoiding the accumulation of ice crystals affecting the heat transfer efficiency of the equipment and increasing the energy consumption of the equipment. After being used for a period of time, the front end of the scraper of the existing ice scraper is hit by ice cubes and becomes chipped or worn, resulting in incomplete ice scraping or scratching the cooling pipe, affecting the service life of the equipment. Therefore, the scraper needs to be replaced regularly. In the prior art, the scraper is mostly fixed by bolts. When replacing, the equipment needs to be disassembled as a whole, and then the fixing bolts of the scraper are removed. The scraper is removed, which is very inconvenient. Therefore, an ice scraper structure of freezing concentration equipment is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 5 , an ice scraper structure of a freezing concentration device, comprising a refrigerant pipe 1 and a fixing frame 3, wherein an ice scraper mechanism 2 is arranged on the refrigerant pipe 1;

[0024] The ice scraping mechanism 2 includes a scraper 220, a scraper 210, a motor 240 and a screw rod 230. The motor 240 is fixedly mounted on the top of the fixing frame 3. The screw rod 230 passes through the fixing frame 3 and is rotatably connected thereto. A first screw hole 221 is provided at the center of the scraper 220. The screw rod 230 passes through the first screw hole 221 and is threadedly connected to the scraper 220. The scraper 220 is provided with mounting holes 222 that are precisely matched with the layout and number of the refrigerant pipe 1. The scraper 210 is detachably mounted in the mounting holes 222. The scraper 210 is composed of a first knife ring 212 and a second knife ring 211. A limiting mechanism 4 is provided on the upper end surface of the scraper 220.

[0025] When the ice scraper is in use, first, start the motor 240 to drive the screw rod 230 to rotate, so that the scraper 220 makes a reciprocating motion along the refrigerant pipe 1 to start the ice scraping operation. If the scraper 210 needs to be replaced, turn off the motor 240, pull out the latch 410, and rotate the knob plate 216 counterclockwise to rotate the scraper 210 out of the mounting hole 222. According to the design of the slide groove 217 and the slider 214, the first knife ring 212 and the second knife ring 211 of the new scraper 210 are slid and spliced ​​in the longitudinal direction, and the magnet 215 is used to fix it to ensure that the bottoms of the first knife ring 212 and the second knife ring 211 are aligned. The scraper 210 is threadedly connected to the mounting hole 222 on the scraper 220 through the external thread, the knob plate 216 is rotated until it is tightened, the latch 410 is inserted, and the scraper 210 is rotated in the opposite direction so that the top of the scraper 210 is against the latch 410 to ensure that the scraper 210 and the scraper 220 are tightly matched.

[0026] Furthermore, the first knife ring 212 and the second knife ring 211 are semicircular ring structures, a slide groove 217 is provided on the top of the side end surface of the first knife ring 212, and a slider 214 is provided on the top of the side end surface of the second knife ring 211. The first knife ring 212 and the second knife ring 211 are slidably connected through the slide groove 217 and the second slider 214.

[0027] The slidingly connected first blade ring 212 and second blade ring 211 can be directly assembled on the refrigerant pipe 1, so that the scraper 210 can be quickly removed without disassembling the refrigerant pipe 1 and the ice scraper plate, which greatly improves the convenience of replacing the scraper 210.

[0028] Furthermore, the top-view cross-section of the slider 214 and the slide groove 217 is an isosceles trapezoidal structure. Magnets 215 with opposite magnetic poles are arranged inside the slider 214 and at the bottom of the slide groove 217. The first knife ring 212 and the second knife ring 211 are fixed by adsorption via the first magnet 215.

[0029] After the slider 214 and the slide groove 217 are matched, they can only move longitudinally, avoiding the first knife ring 212 and the second knife ring 211 from shaking after installation, thereby improving the stability of the scraper 210. The first knife ring 212 and the second knife ring 211 are fixed by adsorption through the magnet 215, so that the external threads of the first knife ring 212 and the second knife ring 211 remain aligned, avoiding the first knife ring 212 and the second knife ring 211 from being misaligned during installation, causing the bottom of the first knife ring 212 and the second knife ring 211 to be unable to be aligned, affecting the ice scraping effect.

[0030] Furthermore, the inner end surface of the mounting hole 222 is provided with an internal thread, and the outer end surface of the scraper 210 is provided with an external thread corresponding thereto. The scraper 210 is inserted into the mounting hole 222 and is threadedly connected to the scraper plate 220 .

[0031] The threaded installation structure facilitates installation of the scraper 210 , and under the constraint of the thread, can prevent the first knife ring 212 and the second knife ring 211 from being misaligned during use, thereby improving the stability of the first knife ring 212 and the second knife ring 211 .

[0032] Furthermore, a knob plate 216 is provided on the top of the first knife ring 212 and the second knife ring 211 .

[0033] The scraper 210 can be conveniently rotated by the knob plate 216, so that the scraper 210 can be conveniently installed and removed without the aid of external tools, which greatly improves the convenience of equipment installation and removal.

[0034] Furthermore, the bottom of the scraper 210 is a conical structure, and a guide groove 213 is provided at the bottom of the side end surface of the scraper 210 .

[0035] The guide groove 213 can increase the contact area between the scraper 210 and the ice surface. The groove-like structure can form a "blade"-like effect. When the ice scraper moves, these blades can exert additional shear force on the ice layer, making it easier to cut or peel off the ice. The guide groove 213 can serve as a channel for ice chips, guiding the broken ice chips to slide smoothly along the groove direction, avoiding the accumulation of ice chips on the surface of the ice scraper to hinder its continued scraping, thereby maintaining the scraping efficiency.

[0036] Furthermore, the limiting mechanism 4 includes a latch 410 and a guide frame 420 . A guide hole is formed between the guide frame 420 and the upper end surface of the scraper 220 . The latch 410 is inserted into the guide hole and is slidably connected to the scraper 220 .

[0037] The latch 410 is pressed against the top of the scraper 210 to prevent the scraper 210 from deviating upward and loosening during use, causing the scraper 210 to fall off, thereby improving the stability of the ice scraper.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
