Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a segmented drying device for crystallization water. Background Technology

[0002] In the prior art, the drying of materials containing water of crystallization is mostly carried out using intermittent drying equipment (such as box-type drying ovens) or ordinary continuous drying equipment (such as belt dryers and drum dryers). Among them, continuous disc dryers are gradually being used in the drying of water of crystallization due to their small footprint and high thermal efficiency. However, when existing continuous disc dryers are used for drying water of crystallization, they have problems such as incomplete drying, low thermal efficiency, high energy consumption, easy material sticking to the wall and accumulation, and poor dehumidification effect. Therefore, those skilled in the art have provided a segmented drying device for water of crystallization to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this invention is to provide a segmented drying device for crystallization water to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a segmented drying device for crystallization water, comprising a storage tank, a feed pipe connected to the top of the storage tank, multiple heating plates vertically arranged and fixedly connected inside the storage tank, and a motor fixedly connected to the bottom of the lowest heating plate, a rotating rod fixedly sleeved on the outer wall of the output shaft of the motor, the rotating rod passing through the multiple heating plates and extending to the top of the uppermost heating plate, multiple sets of scrapers symmetrically arranged and fixedly connected to the outer wall of the heating plates, and the multiple sets of scrapers respectively adhering to the top and inner wall of the multiple heating plates, two heat inlet pipes symmetrically connected to the bottom of the storage tank, two dehumidification pipes symmetrically connected to the top of the storage tank, and a discharge pipe connected to the bottom of the storage tank.

[0005] As a further improvement of this utility model: the heating plate has a hollow structure, and multiple heating plates are connected by the same liquid guide pipe.

[0006] As a further improvement of this utility model: both sides of the storage tank are connected to circulation pipes, and the circulation pipes are connected to vent pipes.

[0007] As a further embodiment of this utility model: an air distribution plate is fixedly connected to the inner wall of the storage tank, and the air distribution plate is located above the air outlet of the heat inlet pipe and below the lowest heating plate.

[0008] As a further improvement of this utility model: the bottom of each of the multiple heating plates is symmetrically connected to two liquid outlet pipes, and each of the multiple liquid outlet pipes is equipped with an electric water valve.

[0009] As a further improvement of this utility model: the bottom opening of the feed pipe faces the uppermost heating plate, and the number of heating plates is three.

[0010] As a further improvement of this utility model: the circulation pipe is U-shaped and is installed horizontally.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] Hot air is introduced into the inlet pipe to work with the air distribution plate to evenly distribute the hot air. The heat is recovered and reheated using the circulation pipe and the exhaust pipe before being sent back into the inlet pipe to complete the circulation. This can significantly improve the utilization rate of hot air and reduce heat waste. The heating plate is made of stainless steel, which can improve heat transfer efficiency and reduce the energy consumption per unit of material drying. The edge of the heating plate is equipped with a baffle, and a polytetrafluoroethylene non-stick coating can be applied to the baffle. Then, it can be scraped with a scraper to effectively prevent material from sticking to the wall and accumulating, reduce the number of downtime cleanings, reduce maintenance costs, and increase the continuous operation time of the equipment.

[0013] This invention is simple to use. The multi-layer heating plate design, combined with a scraper for stirring, increases the residence time of the crystal water, resulting in uniform heating. The scraper also scrapes the heating plate and its edges, effectively preventing material from sticking to the walls. The heating circulation system, consisting of a heat inlet pipe, air distribution plate, air outlet pipe, and circulation pipe, distributes and circulates hot air evenly, significantly improving hot air utilization and reducing heat waste. Furthermore, the connection of two exhaust pipes to a dehumidifier allows for effective dehumidification. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 In this embodiment of the present invention, a segmented drying device for crystallization water includes a storage tank 1. A feed pipe 2 is connected to the top of the storage tank 1. Multiple heating plates 13 are vertically arranged and fixedly connected inside the storage tank 1. A motor 10 is fixedly connected to the bottom of the lowest heating plate 13. A rotating rod 11 is fixedly sleeved on the outer wall of the output shaft of the motor 10. The rotating rod 11 passes through the multiple heating plates 13 and extends to the top of the uppermost heating plate 13. Multiple sets of scrapers 12 are vertically arranged and symmetrically fixedly connected to the outer wall of the heating plates 13. The multiple sets of scrapers 12 are respectively attached to the top and inner wall of the multiple heating plates 13. Two heat inlet pipes 6 are symmetrically connected to the bottom of the storage tank 1. Two dehumidification pipes 3 are symmetrically connected to the top of the storage tank 1. A discharge pipe 7 is connected to the bottom of the storage tank 1.

[0021] In this embodiment, the heating plate 13 has a hollow structure, and multiple heating plates 13 are connected by the same liquid guide pipe 8.

[0022] In this embodiment, both sides of the storage tank 1 are connected to circulation pipes 5, and the circulation pipes 5 are connected to vent pipes 4.

[0023] In this embodiment, an air distribution plate 9 is fixedly connected to the inner wall of the storage tank 1, and the air distribution plate 9 is located above the air outlet of the heat inlet pipe 6 and below the bottom heating plate 13.

[0024] In this embodiment, the bottoms of the multiple heating plates 13 are symmetrically connected to two liquid outlet pipes 14, and each of the multiple liquid outlet pipes 14 is equipped with an electric water valve 15.

[0025] In this embodiment, the bottom opening of the feed pipe 2 faces the uppermost heating plate 13, and there are three heating plates 13.

[0026] In this embodiment, the circulation pipe 5 is U-shaped and installed horizontally. The heating plate 13 is made of stainless steel, which can improve heat transfer efficiency and reduce energy consumption for drying a unit of material. The heating plate 13 has a baffle edge, and a polytetrafluoroethylene anti-stick coating can be applied to the baffle edge. Then, it is scraped with the scraper 12 to effectively prevent material from sticking to the wall and accumulating, reduce the number of downtime cleanings, reduce maintenance costs, and increase the continuous running time of the equipment. By connecting the dehumidifier to the exhaust pipe 3 above, dehumidification can be effectively carried out.

[0027] The working principle of this utility model is as follows: The heating plate 13 has a hollow structure and can be filled with heat transfer oil for heating. Multiple heating plates 13 transfer heat transfer oil to each other through the liquid guide pipe 8. The scraper 12 is used for stirring, and the liquid outlet pipe 14 and electric water valve 15 are used for flow control, so that the material stays on the heating plate 13 for a uniform time and can fully contact the heating surface. This can remove the water in the crystallization more thoroughly, thereby stabilizing the moisture content of the finished product. Hot air is introduced into the heat inlet pipe 6 and used with the air distribution plate 9 to distribute the hot air evenly. The heat is recovered by the circulation pipe 5 and the air outlet pipe 4 and then sent back into the heat inlet pipe 6 after reheating to complete the circulation. This can greatly improve the utilization rate of hot air and reduce heat waste.
