Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a sodium diacetate drying and cooling integrated machine. Background Technology

[0002] Sodium diacetate is prone to absorbing moisture and clumping. Traditional drying methods, especially high-temperature and long-term drying, can easily cause its surface to melt and form a crust, making it difficult for internal moisture to evaporate. When using static drying (such as an oven) or uneven airflow for drying, hard lumps are easily formed, requiring secondary crushing. In addition, because sodium diacetate is also prone to reabsorbing moisture at high temperatures, direct packaging after traditional single-stage drying will affect product quality. The drying exhaust gas contains fine particles, and direct emission will cause waste and dust pollution. Utility Model Content

[0027] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0028] Example:

[0029] The accompanying drawings illustrate a specific embodiment of the sodium diacetate drying and cooling integrated machine of this utility model. Figure 1 It mainly includes a drying chamber 1, with a feed inlet 1d at the top and a feeding bin 2 at the top. The output end of the feeding bin 2 is connected to the feed inlet 1d via a solenoid valve 2a. When feeding, the solenoid valve 2a is opened, and the material in the feeding bin 2 enters the drying chamber 1 through the feed inlet 1d.

[0030] The drying chamber 1 is arranged from top to bottom as follows: an upper drying zone 1a, a middle material discharge zone 1b, and a lower cooling zone 1c. A material discharge mechanism 3 is provided between the upper drying zone 1a and the middle material discharge zone 1b to isolate or connect the two zones. Figure 1 , Figure 2 The material feeding mechanism 3 specifically includes a ring of overlapping protrusions 301 on the inner wall of the drying chamber 1. The overlapping protrusions 301 have an opening 301a in the middle. The bottom of the overlapping protrusions 301 is rotatably connected to an opening and closing plate 303 driven by an opening and closing motor through a fixed platform 302. There are two opening and closing plates 303, which are symmetrically arranged. The two opening and closing plates 303 can cooperate to close or open the opening 301a, thereby receiving or releasing materials. There are two opening and closing motors for driving the two opening and closing plates 303 to rotate respectively. The opening and closing motors are installed on the outside of the drying chamber 1.

[0031] After the material falls into the drying chamber 1, it is received by the cooperation of the overlapping boss 301 and the opening and closing plate 303, and then the material can be dried. After the drying is completed, the opening and closing plate 303 is driven by the opening and closing motor to rotate downward, so that the material falls through the middle material dropping area 1b into the lower cooling area 1c, and then the material can be cooled.

[0032] An upper stirring mechanism 4 is provided in the upper drying zone 1a. The upper stirring mechanism 4 includes an upper stirring bracket 402 driven by an upper stirring motor 401. The upper stirring motor 401 is installed on the top of the drying chamber 1, and the output shaft of the upper stirring motor 401 passes through the drying chamber 1 and is connected to the upper stirring bracket 402. The bottom of the upper stirring bracket 402 is provided with multiple spaced vertical stirring rods 403 and an edge stirring plate 404. The multiple vertical stirring rods 403 are located in the opening 301a, and there is a gap between the vertical stirring rods 403 and the opening and closing plate 303. The vertical stirring rods 403 can play the main role in stirring the material. The edge stirring plate 404 contacts the upper surface of the overlapping boss 301, which can realize the auxiliary stirring of the material and the cleaning function of the edge material, sweeping the edge material off.

[0033] The lower cooling zone 1c is equipped with a lower stirring mechanism 5, combined with Figure 1 , Figure 3The lower stirring mechanism 5 includes a lower stirring bracket 502 driven by a lower stirring motor 501. The lower stirring motor 501 is installed at the bottom of the drying chamber 1, and the output shaft of the lower stirring motor 501 passes through the drying chamber 1 and is connected to the lower stirring bracket 502. The bottom of the lower stirring bracket 502 is provided with a lower stirring plate 503, which contacts the bottom surface of the drying chamber 1, and can realize the stirring and cleaning function of the material, and can discharge the material from the drying chamber 1.

[0034] In this embodiment, the vertical stirring rod 403, the edge stirring plate 404, and the lower stirring plate 503 are all made of flexible materials, which can play a certain role in protecting the materials.

[0035] Combination Figure 1 The upper drying zone 1a is connected to a hot air supply system 6, which includes a first air inlet pipe 601, a blower 602, a steam heat exchanger 603, and a hot air inlet pipe 604 connected in sequence. Upper flow equalization plates 10, connected to the upper drying zone 1a, are respectively provided on both sides of the drying chamber 1. One upper flow equalization plate 10 is connected to the hot air inlet pipe 604, and the other upper flow equalization plate 10 is connected in sequence to a hot air outlet pipe 605 and a bag filter 606. A moisture sensor 607 is also provided on the hot air outlet pipe 605.

[0036] Air is drawn into the steam heat exchanger 603 through the first air inlet pipe 601 and heated to the specified temperature by the blower 602. The hot air is then blown evenly into the upper drying zone 1a through the hot air inlet pipe 604 under the action of the upper flow equalization plate 10. The material is fully dried under the stirring of the upper stirring mechanism 4. The hot air containing moisture is discharged into the bag filter 606 for dust removal through the upper flow equalization plate 10 on the other side and the hot air outlet pipe 605. The moisture sensor 607 detects the moisture content. If the moisture content is too high, the hot air temperature can be increased. After the moisture content is detected to meet the standard, the material drying is completed. The material can be released to the lower cooling zone 1c for further cooling by opening the feeding mechanism 3. The high-temperature exhaust gas discharged from the upper drying zone 1a is recovered by the bag filter 606. The recovered dust can be returned to the feed inlet 1d for reuse or collected and treated centrally, thereby reducing waste and dust pollution.

[0037] The lower cooling zone 1c is connected to a cold air supply system 7, which includes a second air inlet pipe 701, a finned precooler 702, a finned evaporator 703, and a cold air inlet pipe 704 connected in sequence. Lower flow equalization plates 11, connected to the lower cooling zone 1c, are provided on both sides of the drying chamber 1. One lower flow equalization plate 11 is connected to the cold air inlet pipe 704, and the other lower flow equalization plate 11 is connected in sequence to a filter 705 and a fresh air preheating pipe 706, which is connected to the first air inlet pipe 601.

[0038] Air enters the finned evaporator 703 for dehumidification after being pre-cooled by the finned precooler 702 through the second air inlet pipe 701. The dehumidified cold air is then blown evenly into the lower cooling zone 1c through the cold air inlet pipe 704 under the action of the lower flow equalization plate 11. The material is fully cooled by the stirring of the lower stirring mechanism 5. The exhaust air after heat exchange in the lower cooling zone 1c is filtered by the filter 705 through the lower flow equalization plate 11 on the other side, and then discharged into the first air inlet pipe 601 through the fresh air preheating pipe 706 for mixing and preheating of the air. This achieves waste heat recovery and utilization, which can significantly reduce energy consumption compared to heating with fresh air.

[0039] The bottom of the drying chamber 1 is also equipped with a discharge mechanism 8, which is connected to a vibrating screen device 9. Combined with... Figure 1 , Figure 3 The bottom of the drying oven 1 is provided with a discharge port 1e. The discharge mechanism 8 includes a receiving box 801 located at the discharge port 1e. The outside of the receiving box 801 is provided with a discharge cylinder 802. The inside of the receiving box 801 is provided with a lifting frame 803 driven to rise and fall by the discharge cylinder 802. The lifting frame 803 is provided with a sealing plug 805 driven to rotate by a discharge motor 804. The sealing plug 805 is adapted to the discharge port 1e.

[0040] After the material has cooled down, the discharge cylinder 802 is activated to drive the lifting frame 803 to descend, causing the sealing plug 805 to disengage from the discharge port 1e. Then, the discharge motor 804 drives the sealing plug 805 to rotate to one side to avoid the material. Under the action of the lower stirring mechanism 5, the material is swept from the discharge port 1e and falls into the receiving box 801.

[0041] The receiving box 801 is also equipped with a vibration mechanism 806 on its exterior. The bottom of the receiving box 801 is connected to the vibrating screening device 9 via a flexible hose 807. Under the impact of the vibration mechanism 806, the material in the receiving box 801 falls into the vibrating screening device 9 through the flexible hose 807. The vibrating screening device 9 can automatically screen out qualified particles from the material for easy packaging.

[0042] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model, and their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit and essence of the main technical solution of this utility model should be covered within the protection scope of this utility model.
