[0001] The utility model belongs to the technical field of evaporators, in particular to a mother liquor circulation evaporation device for baking soda equipment. Background Art

[0002] Baking soda is a chemical substance, a white crystal. Its chemical name is sodium bicarbonate. Baking soda is found in both the food and pharmaceutical industries.

[0003] During the production and processing of baking soda, another substance called baking soda mother liquor will appear. The texture of baking soda mother liquor is not simple. It may be baking soda or ammonium chloride. Therefore, when baking soda mother liquor appears, it is necessary to filter the mother liquor to ensure pure baking soda. At the same time, the filtered mother liquor can be used in other scenarios after subsequent processing.

At this time, as the card block 22 is installed, the water outlet pipe 23 will also be installed to the specified position, that is, the first support Below the plate 12, the water outlet pipe 23 is connected to the middle of the filter barrel 13. At this time, the mother liquor that is filtered again inside the filter barrel 13 will enter the inside of the water outlet pipe 23 as the water outlet pipe 23 is connected. Since the end of the water outlet pipe 23 is downward, the mother liquor will flow along the guidance of the water outlet pipe 23 after entering the inside of the water outlet pipe 23, and then be discharged through the end of the water outlet pipe 23. At this time, the end of the water outlet pipe 23 is located inside the collecting box 24, so the discharged mother liquor will enter the inside of the collecting box 24. Through the above structure, the mother liquor that is filtered for the second time inside the filter barrel 13 can be discharged, and the residual baking soda inside the filter barrel 13 can be conveniently collected. At the same time, the unified collection of the mother liquor is also realized, reducing the pollution to the environment caused by the disorderly discharge of the mother liquor.

During operation, as the water suction pump is started, the mother liquor inside the circulating evaporator body 1 will enter the inside of the filter barrel 13 to complete the secondary filtration. At this time, as the water suction pump is started, the first water pipe 14 will shake. As time goes by, the first water pipe 14 will loosen. At this time, a fixing ring 4 is installed in the middle of the first water pipe 14, and then the fixing ring 4 and the side wall of the circulating evaporator body 1 are connected by the fixing rods 41. Through the above structure, the first water pipe 14 can be fixed at a specified position, which reduces the shaking of the first water pipe 14 caused by the long-term operation of the water suction pump, thereby reducing the loosening.

During operation, the cleaning liquid inside the water tank 31 will enter the inside of the second water pipe 32 as the water pump is started, and then sprayed to the inside of the filter barrel 13. At this time, the cleaning liquid entering the inside of the second water pipe 32 will be sprayed out from the end of the second water pipe 32. At this time, the sprayed cleaning liquid will first enter the inside of the flow diffuser 5, and then contact the second grid plate 51. At this time, the cleaning liquid will be blocked by the second grid plate 51, and then sprayed out from the gap in the middle of the second grid plate 51. Through the above structure, the cleaning liquid can be sprayed more widely to the inside of the filter barrel 13, so that the inside of the filter barrel 13 is cleaned more comprehensively, and the occurrence of baking soda or mother liquor remaining in the filter barrel 13 is further reduced.

Through the above structure, the card block 22 can be installed into the interior of the card slot 21 more conveniently along the guidance of the guide plates 6, thereby reducing the time for installing the card block 22.

[0029] like Figure 3 As shown, the end of the second water pipe 32 is located above the end of the first water pipe 14. During operation, since the end of the second water pipe 32 is located above the end of the first mesh plate 17, the cleaning liquid will also be sprayed to the end of the first mesh plate 17 at the same time. Through the above arrangement, the end of the first mesh plate 17 can be cleaned while the inside of the filter barrel 13 is cleaned.

[0030] During operation, the raw material liquid containing baking soda is placed inside the circulating evaporator body 1, and then the circulating evaporator body 1 is started. At this time, as the circulating evaporator body 1 is started, the baking soda is stationary inside the circulating evaporator body 1. At this time, the solid baking soda will settle at the bottom of the circulating evaporator body 1, and the mother liquor will float above the baking soda. At this time, by installing a water suction pump at the end of the first water pipe 14, and then starting the water suction pump, the mother liquor floating above the baking soda will enter the first water pipe 14 as the water pump is started, and at the same time, it will continue to flow along the contour of the first water pipe 14 until it flows to the end of the first water pipe 14 and contacts the ends of multiple diversion pipes 19. At this time, the mother liquor will be filtered through the first mesh plate 17, and then the mother liquor It will enter the interior of the filter barrel 13 with the guidance of multiple branch pipes 19. At this time, the mother liquor falling into the filter barrel 13 will fall into the interior of the conical barrel 15. At this time, the mother liquor is allowed to stand, and then the remaining baking soda particles will fall to the bottom of the conical barrel 15. A water suction pump can be installed at the end of the first water pipe 14, and then the mother liquor floating on the baking soda is brought into the interior of the filter barrel 13 by the water suction pump. At the same time, the mother liquor is filtered again in the filter barrel 13, and the block 22 is installed in the card slot 21. At this time, as the block 22 is installed, the water outlet pipe 23 will also be installed at the specified position, that is, below the first support plate 12. At this time, the water outlet pipe 23 is connected to the middle of the filter barrel 13. At this time, the mother liquor filtered again in the filter barrel 13 As the outlet pipe 23 is connected, it will enter the interior of the outlet pipe 23. Since the end of the outlet pipe 23 is downward, the mother liquor will flow along the guidance of the outlet pipe 23 after entering the interior of the outlet pipe 23, and then be discharged through the end of the outlet pipe 23. At this time, the end of the outlet pipe 23 is located inside the collecting box 24, so the discharged mother liquor will enter the interior of the collecting box 24. When the mother liquor and baking soda in the filter barrel 13 are taken out, the cleaning liquid can be filled in the water tank 31, and the water pump in the water tank 31 is started synchronously. As the water pump is started, the cleaning liquid in the water tank 31 will be filled into the second water pipe 32. At this time, as the water pump is driven, the cleaning liquid will continue to flow along the contour of the second water pipe 32 until it flows to the end of the second support plate 3. At this time, the cleaning liquid will be sprayed into the interior of the filter barrel 13. With the start of the water suction pump, the mother liquid inside the circulating evaporator body 1 will enter the interior of the filter barrel 13 to complete the secondary filtration. At this time, with the start of the water suction pump, the first water pipe 14 will shake. As time goes by, the first water pipe 14 will loosen. At this time, by installing a fixing ring 4 in the middle of the first water pipe 14, and then connecting the fixing ring 4 and the side wall of the circulating evaporator body 1 through a fixing rod 41, the cleaning liquid inside the water tank 31 will enter the interior of the second water pipe 32 as the water pump is started, and then sprayed into the interior of the filter barrel 13. At this time, the cleaning liquid entering the second water pipe 32 will be sprayed out from the end of the second water pipe 32. At this time, the sprayed cleaning liquid will first enter the interior of the expansion tube 5.Then it contacts the second mesh plate 51, at which time the cleaning liquid will be blocked by the second mesh plate 51, and then it will be sprayed out from the gap in the middle of the second mesh plate 51, and along the side wall of the guide plate 6, the card block 22 can be installed into the inside of the card slot 21.
