Description

Technical Field

[0001] This utility model relates to the field of chemical separation technology, and in particular to a static crystallization separation device. Background Technology

[0002] A static crystallizer is a device used for crystallization operations. A common static crystallizer is a container containing many cooling fins. The cooling medium circulates in the fins. The raw material liquid inside the static crystallizer is a saturated solution at a high temperature that flows outside the fins. As the cooling medium circulates inside the separator, crystals will appear on the surface of the fins.

[0003] Since the crystallized products will coat the surface of the fin, the heat conduction efficiency of the fin will decrease as the number of crystals on the fin surface increases. It can be seen that when the number of crystals on the fin surface increases, the crystallization efficiency of the fin will decrease. Utility Model Content

[0004] To address the problem mentioned in the background art that an increase in crystals on the fin surface leads to a decrease in the fin's crystallization efficiency, this utility model provides the following technical solution:

[0005] A static crystallization separation apparatus, comprising a separation chamber;

[0006] The separation chamber is equipped with a crystallization assembly to facilitate crystallization, and a crystallization collection device is installed at the lower end of the separation chamber to scrape off the crystals on the crystallization assembly.

[0007] The separation box is equipped with a reciprocating screw for controlling the crystallization collection device to move back and forth, and a power box for controlling the rotation of the reciprocating screw is installed at the upper end of the separation box.

[0008] The crystallization collection device includes a scraping component for scraping off crystals on the crystallization assembly, and a collection box for collecting the crystals is installed at the lower end of the scraping component.

[0009] Furthermore, the upper end of the separation box is equipped with a raw material inlet for conveying raw material liquid into the separation box, and the lower end of the separation box is equipped with a raw material outlet for conveying raw material liquid to the outside of the separation box. The upper end of the crystallization component is equipped with a cold medium inlet and a cold medium outlet, and the crystallization component shown includes fins.

[0010] Furthermore, a guide rod for limiting the scraping assembly is installed at the upper end of the separation box, and a first bevel gear is installed at the front end of the reciprocating screw.

[0011] Furthermore, there are two reciprocating lead screws, which are distributed at the upper left and right ends of the separator box. A rotating rod is installed inside the power box. Second bevel gears for meshing with the first bevel gear are installed at the left and right ends of the rotating rod. A motor for controlling the rotation of the rotating rod is installed at the right end of the power box.

[0012] Furthermore, the scraping assembly includes a U-shaped plate, a slider is installed on the inner wall of the U-shaped plate, and threaded holes are machined on the bottom of the left and right sides of the U-shaped plate.

[0013] Furthermore, the upper ends of the left and right sides of the U-shaped plate are equipped with screw nuts for cooperating with the reciprocating screw to control the U-shaped plate to move back and forth, and the upper middle part of the U-shaped plate is equipped with multiple scrapers for scraping the crystals on the fins of the crystallization assembly.

[0014] Furthermore, a partition mesh plate for limiting the crystals is installed in the middle of the collection box, and multiple leakage channels for the raw material liquid to flow out are opened at the bottom of the collection box.

[0015] Furthermore, the left and right sides of the collection box are equipped with sliders two for supporting the U-shaped plates of the slider pair. An L-shaped stop is installed on one side of the slider two, and a bolt for locking the scraping component is installed at the bottom center of the L-shaped stop to cooperate with the threaded hole.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] After crystals form on the fins of the crystallization assembly, the motor starts, causing the rotating rod to drive the second bevel gear to rotate. The second bevel gear, in conjunction with the first bevel gear, drives two reciprocating screws to rotate synchronously. The reciprocating screws, in conjunction with the screw nut, drive the U-shaped plate to move back and forth, causing the scraper to scrape off the crystals on the separation box. The scraped crystals fall into the collection box, and finally, the collection box at the lower end of the scraping assembly can be disassembled and removed from the inside of the separation box. This invention allows for continuous crystallization on the fins of the crystallization assembly after the crystals are scraped off by the scraper, thus improving the crystallization efficiency of the fins.

[0027] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0028] Please see Figures 1-6This utility model provides a static crystallization separation device, including a separation chamber 100. A raw material inlet 10 for conveying raw material liquid into the separation chamber 100 is installed at the upper end of the separation chamber 100, and a raw material outlet 20 for conveying raw material liquid to the outside of the separation chamber 100 is installed at the lower end of the separation chamber 100. A crystallization assembly 110 for facilitating crystallization is installed inside the separation chamber 100. The crystallization assembly 110 is prior art, for example, a static crystallization separator disclosed in Chinese Patent Application No. CN202121547665.6, which includes plates for heat exchange. A horizontal block 113 is installed in the middle of the crystallization component 110 of this invention. Support blocks 30 are fixedly installed on the inner walls of the front and rear ends of the separation box 100 to support the crystallization component 110 in conjunction with the horizontal block 113, so that the crystallization component 110 is located in the middle of the inner cavity of the separation box 100. When crystallization separation of the raw liquid is required, the valve on the raw liquid outlet 20 is closed, and the raw liquid is introduced into the box of the separation box 100 through the raw liquid inlet 10, so that the crystallization component 110 is immersed in the raw liquid. Through the transport of the cold medium by the crystallization component 110, crystals are formed on the fins 114 of the crystallization component 110. A crystallization collection device 200 is installed at the lower end of the separation box 100 for scraping off the crystals on the crystallization component 110.

[0029] The upper end of the crystallization assembly 110 is equipped with a cold medium inlet 111 and a cold medium outlet 112 (i.e., the inlet of the crystallization assembly 110 is connected to the cold medium inlet 111, and the outlet of the crystallization assembly 110 is connected to the cold medium outlet 112). The crystallization assembly 110 includes a fin 114, and the upper ends of the cold medium inlet 111 and the cold medium outlet 112 are located outside the separation box 100. The arrangement of the cold medium inlet 111 and the cold medium outlet 112 facilitates the flow of cold medium within the crystallization assembly 110. The separation box 100 is equipped with a reciprocating screw 120 for controlling the back-and-forth movement of the crystallization collection device 200. The reciprocating screw 120 is located above the separation box 100, and a first bevel gear 121 is fixedly installed at the front end of the reciprocating screw 120.

[0030] The upper end of the separator 100 is equipped with a power box 140 for controlling the rotation of the reciprocating screw 120. There are two reciprocating screws 120, which are distributed at the front and rear ends of the upper part of the separator 100, and the two reciprocating screws 120 rotate synchronously. The power box 140 is equipped with a rotating rod 141. The left and right ends of the rotating rod 141 are fixedly equipped with a second bevel gear 142 for meshing with the first bevel gear 121. The right end of the power box 140 is equipped with a motor 143 for controlling the rotation of the rotating rod 141. After crystals are formed on the fins 114 of the crystallization assembly 110, the starting of the motor 143 causes the rotating rod 141 to drive the second bevel gear 142 to rotate. The second bevel gear 142, in conjunction with the first bevel gear 121, drives the two reciprocating screws 120 to rotate synchronously, so that the crystallization collection device 200 moves back and forth under the guidance of the reciprocating screws 120, so that the crystallization collection device 200 can scrape off the crystals on the crystallization assembly 110.

[0031] The crystallization collection device 200 includes a scraping assembly 210 for scraping crystals off the crystallization component 110. The scraping assembly 210 is positioned inside the cross block 113. A guide rod 130 is installed at the upper end of the separation box 100 to limit the scraping assembly 210. A limiting frame is installed on the top of the separation box 100 to limit the guide rod 130 and the reciprocating screw 120. The top cover plate of the limiting frame is fixed to the limiting frame by bolts. The scraping assembly 210 can only move back and forth. The scraping assembly 210 includes a U-shaped plate 211, and multiple sliders 212 are fixedly installed on the inner wall of the U-shaped plate 211.

[0032] Threaded holes 213 are machined at the bottom of both sides of the U-shaped plate 211. The upper ends of both sides of the U-shaped plate 211 pass through the slotted opening of the top plate of the separation box 100 and are fixedly installed with screw nuts 214 for cooperating with the reciprocating screw 120 to control the forward and backward movement of the U-shaped plate 211. The top of the separation box 100 has a groove for facilitating the left and right movement of the screw nuts 214. The slotted opening of the top plate of the separation box 100 can be equipped with a linear sliding sealing structure, such as grooves on both sides of the lower connecting rod wall of the screw nut 214, with rubber strips passing through the grooves. A level gauge can be installed inside the separation box 100. By setting the level gauge, the supply of raw material can be stopped when the raw material liquid reaches the position submerging the fin plate 114, without completely filling the separation box; the upper end of the raw material liquid is below the top plate of the separation box 100.

[0033] When the reciprocating lead screw 120 rotates, it synchronously drives the U-shaped plate 211 to move back and forth in conjunction with the lead screw nut 214. The upper end of the lead screw nut 214 has a cavity for the guide rod 130 to slide (the cavity for the guide rod 130 to slide is...). Figure 4The upper hole of the lead screw nut 214 and the lower hole of the lead screw nut 214 are threaded holes through which the reciprocating lead screw 120 rotates. Multiple scrapers 215 for scraping the crystals on the fins 114 are installed at the upper middle part of the U-shaped plate 211. Each scraper 215 is located between two adjacent fins 114 so that each scraper 215 can scrape the crystals on the two adjacent fins 114 when it moves.

[0034] The scraping assembly 210 is equipped with a collection box 220 for collecting crystals at its lower end. The U-shaped plate 211 is located in the middle of the collection box 220, so that when the scraping assembly 210 moves back and forth, both ends of the collection box 220 can collect crystals. When the U-shaped plate 211 moves backward, the crystals at the rear end of the scraper 215 fall to the rear end of the collection box 220. When the U-shaped plate 211 moves forward, the crystals at the front end of the scraper 215 fall to the front end of the collection box 220.

[0035] The collecting tank 220 has a dividing mesh plate 221 installed in the middle of its body to limit the crystals. Multiple drain channels 225 are provided at the bottom of the collecting tank 220 to allow the raw material liquid to flow out. When discharging the raw material liquid, the liquid inside the separating tank 100 is discharged through the raw material outlet 20. The dividing mesh plate 221 has multiple mesh openings to facilitate the flow of the raw material liquid to the lower end of the collecting tank 220. Finally, the raw material liquid falls through the drain channels 225 to the lower end of the inner cavity of the separating tank 100. After crystallization, the raw material liquid is discharged from the inner cavity of the separating tank 100 through the raw material outlet 20.

[0036] Slider 222, used to support U-shaped plate 211 in conjunction with slider 1 212, is fixedly installed on both sides of the collection box 220. An L-shaped stop 223 is fixedly installed on one side of slider 222. During installation, the collection box 220 is pushed from back to front to the middle of U-shaped plate 211, causing slider 1 212 to rest on top of slider 222. As the collection box 220 is pushed from back to front, the L-shaped stop 223 gradually moves closer to the side wall of U-shaped plate 211, eventually reaching a point where the L-shaped stop 223 and slider 1 212... The side walls abut against each other. The bottom center of the L-shaped stop 223 is equipped with a bolt 224 for locking the scraping component 210 with the threaded hole 213. When the side walls of the L-shaped stop 223 and the slider 212 abut against each other, the collection box 220 can be fixed to the lower end of the U-shaped plate 211 by screwing the threaded end of the bolt 224 into the threaded hole 213. This allows the scraping component 210 to scrape the crystals while moving back and forth, and simultaneously drive the collection box 220 to collect the scraped crystals so that the surface of the crystallization component 110 can continue to crystallize.

[0037] The separation tank 100 has a disassembly port 150 at its rear end. A sealing plate 160 is installed at the rear end of the separation tank 100 to close the disassembly port 150. After the raw material liquid inside the separation tank 100 is discharged, the sealing plate 160 can be disassembled so that when the scraping component 210 moves the collection box 220 to the rear end of the separation tank 100, the collection box 220 can be disassembled so that the crystals on the collection box 220 can be removed.

[0038] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
