Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mother liquor drying equipment, specifically to an evaporation mother liquor drying equipment. Background Technology
[0002] Vacuum evaporators use high-temperature steam to evaporate the mother liquor. The mother liquor is heated instantly by the high-temperature steam, thereby quickly separating the water from the mother liquor. The water then leaves the mother liquor along with the high-temperature steam.
[0003] In existing vacuum drying evaporators, high-temperature steam passes through the mother liquor to form secondary steam. Some of the mother liquor is adsorbed onto the high-temperature steam and is lost with the discharge of the high-temperature steam, resulting in waste of mother liquor, resource waste, and increased production costs.
[0004] Therefore, an evaporation mother liquor drying device is proposed to address the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide an evaporation mother liquor drying device, including an installation frame, with support legs at the four corners of the installation frame, a vacuum evaporation box inside the installation frame, an air inlet pipe at the bottom of the vacuum evaporation box, multiple steam outlets on the air inlet pipe, a mother liquor inlet pipe above the air inlet pipe, multiple nozzles below the mother liquor inlet pipe, a connecting horizontal plate at the top of the vacuum evaporation box, a baffle plate on the left side above the connecting horizontal plate, a baffle plate on the top right side of the vacuum evaporation box above the baffle plate, and a collection hopper on each of the connecting horizontal plates below the baffle plate, with a connecting pipe below the collection hopper, a filter box connected to the upper right side of the vacuum evaporation box via a connecting pipe, an exhaust pipe at the end of the filter box away from the connecting pipe, a discharge pipe at the bottom of the vacuum evaporation box, a collection box at a corresponding position below the discharge pipe, and locking blocks on the upper and lower sides of the collection box, which engage with slots on the inner side of the support legs.
[0006] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0007] This invention features a first baffle, a second baffle, a collection hopper, and a connecting pipe. The second baffle collides with the secondary steam. Due to the large mass of the mother liquor, it has a large inertia, which distinguishes the deceleration effect between the mother liquor and the secondary steam. The evaporated mother liquor falls through the connecting pipe for easy collection.
[0008] This invention features two filter screens that can perform dual filtration of the mother liquor, thereby separating the mother liquor from the steam. This facilitates the collection of the mother liquor remaining in the steam and improves the resource collection rate.
[0009] This utility model incorporates a collection box, a locking block, and a locking slot. The collection box collects the evaporated mother liquor, and the locking block is then removed from the locking slot to facilitate the removal of the collection box, thereby facilitating the collection of the evaporated mother liquor inside the collection box.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] As attached Figure 1 , 2As shown, the present invention provides an evaporation mother liquor drying device, including an installation frame 1. Support legs 2 are respectively provided at the four corners of the lower part of the installation frame 1. A vacuum evaporation chamber 3 is installed inside the installation frame 1. An air inlet pipe 7 is provided at the lower part of the vacuum evaporation chamber 3. Multiple steam outlets 12 are provided on the air inlet pipe 7. A mother liquor inlet pipe 8 is provided above the air inlet pipe 7. Multiple nozzles 13 are provided below the mother liquor inlet pipe 8. A connecting horizontal plate 14 is provided at the upper part of the vacuum evaporation chamber 3. A baffle 15 is provided on the left side above the connecting horizontal plate 14. A baffle 15 is provided on the right side above the baffle 15. The vacuum evaporator 3 is equipped with a baffle plate 16 on the top. The connecting horizontal plates 14 on both sides below the baffle plate 16 are respectively provided with a material collection hopper 141. A connecting pipe 17 is provided below the material collection hopper 141. The upper right side of the vacuum evaporator 3 is connected to the filter box 10 through a connecting pipe 19. An exhaust pipe 11 is provided at the end of the filter box 10 away from the connecting pipe 19. A discharge pipe 4 is provided at the bottom of the vacuum evaporator 3. A material collection box 5 is provided at the corresponding position below the discharge pipe 4. A locking block 6 is provided on the upper and lower sides of the material collection box 5. The locking block 6 is locked into the locking groove 201 opened on the inner side of the support leg 2.
[0017] Specifically, a control valve 18 is provided on the connecting pipe 17.
[0018] Specifically, the filter box 10 is mounted on the fixed plate 9.
[0019] As attached Figure 3 As shown, the filter box 10 includes an outer shell 1001. Two filter screens 1003 are disposed inside the outer shell 1001. An insert block 1004 is disposed below the filter screen 1003. The insert block 1004 is inserted into a slot 1002 opened at the bottom of the inner shell 1001. A stepped groove 1007 is opened on the outer shell 1001 at the corresponding position above the filter screen 1003. The filter screen 1003 is inserted into the stepped groove 1007 and connected to a sealing cover plate 1005 disposed inside the stepped groove 1007. The sealing cover plate 1005 is fixed to the stepped groove 1007 on both sides by fastening bolts 1006.
[0020] Working principle: During use, high-temperature steam is sent in through the inlet pipe 7 and out through the steam outlet 12. At the same time, the mother liquor is sent in through the mother liquor inlet pipe 8 and out through the nozzle 13, spraying the mother liquor into the vacuum evaporation box 3. The high-temperature steam heats, evaporates, and dries the mother liquor. Most of the dried mother liquor is sent out through the discharge pipe 4. When the secondary steam passes through the first baffle 15 and the second baffle 16, it collides with the baffles. Due to the large mass of the mother liquor, its inertia is large, which makes the deceleration effect of the mother liquor and the secondary steam different. The dried mother liquor falls through the connecting pipe. Finally, the remaining small part of the secondary steam is sent into the filter box 10 through the connecting pipe 19. The two filter screens 1003 can perform double filtration of the mother liquor, thereby separating the mother liquor from the steam, making it easier to collect the mother liquor remaining in the steam and improving the resource collection rate.
[0021] Finally, the dried mother liquor sent through the discharge pipe 4 falls into the collection box 5, where the dried mother liquor is collected. Then, the card block 6 is removed from the card slot 201 to facilitate the removal of the collection box 5 and the collection of the dried mother liquor inside the collection box 5.
