Description

Technical Field

[0001] This utility model relates to the field of molecular sieve technology, and more specifically, to a drying device for molecular sieves. Background Technology

[0002] Molecular sieves are materials containing precise and single micropores that can be used to adsorb gases or liquids. During the processing of molecular sieves, carbonization is required. In the process of high-temperature carbonization, the moisture in the raw materials is baked out. Due to the mass production of molecular sieves, some water vapor is not completely separated from the molecular sieves. Therefore, the molecular sieves need to be dried to improve their adsorption capacity.

[0003] During the drying process of molecular sieves, the materials accumulate together. Ordinary drying equipment mainly involves stirring the materials and then blowing them with air. This method is common and widely used. However, molecular sieves themselves have the ability to absorb water. When a large number of molecular sieves are concentrated together, the gaps created by stirring are relatively small, and water vapor is easily reabsorbed by the molecular sieves. The drying process needs to be carried out little by little, and the drying time is correspondingly long. On the other hand, directly spreading out the molecular sieves takes up too much space, and the molecular sieves easily absorb a lot of dust, which is not easy to collect, resulting in low work efficiency. Ordinary molecular sieve drying devices are difficult to lift and separate the accumulated molecular sieves. Molecular sieves easily absorb water vapor from each other, making the molecular sieve drying time long and the work efficiency low.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a drying device for molecular sieves, which has the following beneficial effects:

[0019] (1) This utility model adopts a guide plate and an exhaust hood. The molecular sieve can slide down along the inclined guide plate. When it slides down, the electric heating wire inside the guide plate can generate heat. Then, the air jet hole below the electric heating wire can introduce dry air. When the air passes through the electric heating wire, it can carry away the heat and then discharge it from the flow hole at the top of the guide plate, thereby acting on the molecular sieve to realize the drying operation of the molecular sieve. At the same time, the moisture generated by the molecular sieve when heated can be extracted in time by the exhaust hood above, avoiding the residual moisture from affecting the overall drying effect. In addition, there are multiple sets of guide plates, so the molecular sieve can be continuously dried. When the molecular sieve falls, it will naturally be disturbed, thereby expanding the overall contact area with the hot air, thus better and more fully drying the molecular sieve and improving the overall processing effect. It has the advantages of good drying effect and high drying dispersion.

[0020] (2) This utility model uses a sealing plate and a motor. During operation, the molecular sieve that needs to be dried can be added to the feed cylinder through the feed port. At this time, the operation of the motor can drive the drive shaft to rotate, and the rotation of the drive shaft can drive the sealing plate at the bottom to rotate. When the sealing plate leaves the discharge port, the molecular sieve inside can be discharged smoothly. When the sealing plate is aligned with the discharge port again, the molecular sieve inside will be blocked again. By controlling the speed of the motor, the falling speed of the molecular sieve can be controlled, thereby realizing intermittent discharge operation, avoiding the large amount of molecular sieve discharged and causing it to accumulate together and affect the drying effect. It has the advantage of batch drying. Attached Figure Description

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a molecular sieve drying device according to an embodiment of the present invention includes a body 1 and support legs 18. Several sets of guide plates 2 are installed at staggered angles on both sides of the inner surface of the body 1. Several sets of exhaust hoods 3 are installed parallel to each other on the inner surface of the body 1 above the guide plates 2. An air jet pipe 16 is installed at the bottom of the inner surface of the guide plates 2. Several sets of air jet holes 17 are evenly opened on the surface of the air jet pipe 16. An electric heating wire 15 is installed at the top of the inner surface of the guide plates 2 above the air jet pipe 16. Several sets of flow holes 14 are evenly opened at the top of the guide plates 2. The size of the flow holes 14 is smaller than that of the molecular sieve. The size of the flow holes 14 is set to avoid the molecular sieve getting stuck in them and causing blockage of the holes, thereby ensuring that the hot air can be smoothly applied to the molecular sieve, thereby realizing the drying operation of the molecular sieve.

[0031] In one embodiment, an extraction groove 12 is provided at the bottom of the extraction hood 3. The extraction groove 12 is provided to extract moisture.

[0032] In one embodiment, a feed cylinder 5 is installed on one side of the top of the machine body 1. A drive shaft 8 is installed in the middle of the feed cylinder 5. One end of the drive shaft 8 passes through one side of the feed cylinder 5 and is connected to a motor 7. A sealing plate 9 is installed at the bottom of the drive shaft 8. A discharge port 10 is opened below the sealing plate 9 on one side of the bottom of the feed cylinder 5. A guide plate 11 is installed at an angle between the bottom of the feed cylinder 5 and the top of the exhaust hood 3. The guide plate 11 is set to prevent the falling molecular sieve from falling above the exhaust hood 3, ensuring that the molecular sieve can fall fully onto the guide plate 11, thereby achieving subsequent drying treatment. The single set of sealing plate 9 and discharge port 10 is to achieve intermittent discharge operation, avoid a large amount of molecular sieve concentrated inflow, and ensure the overall drying effect.

[0033] In one embodiment, feed inlets 6 are symmetrically provided on both sides of the bottom of the feed cylinder 5. The feed inlets 6 are provided to facilitate the addition of molecular sieves and subsequent drying.

[0034] In one embodiment, an exhaust fan 4 and a blower 13 are respectively installed at the top positions of the two sides of the body 1.

[0035] In one embodiment, one end of the exhaust fan 4 is connected to the exhaust hood 3 via a pipe. The exhaust fan 4 is designed to extract the moisture generated during the drying of the molecular sieve in a timely manner through the exhaust hood 3, so as to prevent the moisture from accumulating and being absorbed by the molecular sieve, thus ensuring the overall drying effect.

[0036] In one embodiment, one end of the blower 13 is connected to the jet pipe 16 via a pipe. The blower 13 is designed to spray out dry gas, which can then pass through the heating wire 15 and be added to the molecular sieve for drying. To ensure the dryness of the gas, the blower 13 can be directly connected to the external dried gas or a corresponding drying structure or component, such as a desiccant, can be provided at the outlet of the blower 13. Specific measures can be selected and adjusted according to personnel needs, and will not be elaborated further here.

[0037] In one embodiment, support legs 18 are symmetrically installed on both sides of the bottom of the machine body 1, and a discharge port 19 is provided in the middle of the bottom of the machine body 1. The discharge port 19 is provided to discharge the dried molecular sieve, which facilitates subsequent use. The support legs 18 are provided to support and fix the entire device to ensure the stability of operation.

[0038] Working Principle: In actual use, the molecular sieve to be dried is added to the feed cylinder 5 through the feed inlet 6. The motor 7 drives the drive shaft 8 to rotate, which in turn rotates the sealing plate 9 at its bottom. When the sealing plate 9 leaves the discharge port 10, the molecular sieve inside can be smoothly discharged. When the sealing plate 9 realigns with the discharge port 10, the molecular sieve inside is blocked again. By controlling the speed of the motor 7, the falling speed of the molecular sieve can be controlled, thus achieving intermittent discharge operation. This avoids a large amount of molecular sieve being discharged and accumulating, affecting the drying effect. The discharged molecular sieve then slides down the inclined guide plate 2. As it slides down, the heating wire 15 inside the guide plate 2... Heat can be generated, and the jet hole 17 below the heating wire 15 can introduce dry air. When the air passes through the heating wire 15, it can carry away the heat and then discharge it from the flow hole 14 at the top of the guide plate 2, thereby acting on the molecular sieve to achieve the drying operation of the molecular sieve. At the same time, the moisture generated by the molecular sieve when heated can be extracted in time by the exhaust hood 3 above to avoid the moisture residue affecting the overall drying effect. Moreover, the guide plate 2 is equipped with multiple sets, so it can continuously dry the molecular sieve. When the molecular sieve falls, it will naturally be disturbed, thereby increasing the overall contact area with the hot air, so as to better and more fully carry out the drying process and improve the overall processing effect. The device as a whole has the advantages of good drying effect, high drying dispersion, and batch drying.
