Description

Technical Field

[0001] The utility model relates to the technical field of double-cone rotary vacuum dryers, in particular to a double-cone rotary vacuum dryer with a molecular sieve dryer. Background Art

[0002] The double cone rotary vacuum dryer is a double cone rotary tank. In the vacuum state, steam is introduced into the jacket for heating. The heat contacts the wet material through the inner wall of the tank. The water vapor evaporated by the wet material after absorbing heat is pumped away through the vacuum exhaust pipe by the vacuum pump. Since the tank is in a vacuum state and the rotation of the tank makes the material constantly turn upside down and inside and outside, the drying speed of the material is accelerated, the drying efficiency is improved, and the purpose of uniform drying is achieved.

[0003] The double-cone rotary vacuum dryer of this technology is used for drying solid chemical reagents. In actual operation, it is found that most solid reagent products dried by the double-cone rotary vacuum dryer will regain moisture on the upper product during the cooling process, and even form water droplets on the upper part of the bagged product, which has a serious impact on product quality and even forces rework due to non-compliance. The reasons for the above situation are: first, the moisture inside the crystal of the reagent product that is not completely dried escapes during the cooling process, and forms water droplets due to the low temperature on the upper part of the product; second, the reagent product absorbs water in the air during the cooling process and condenses on the surface of the product.

[0004] Therefore, it is urgent to propose a double-cone rotary vacuum dryer with a molecular sieve dryer which has a simple structure and reliable drying. Utility Model Content

[0034] like Figures 1 to 8As shown, the present embodiment provides a double-cone rotary vacuum dryer with a molecular sieve dryer, which includes a mounting base 1, a left support base 2 and a right support base 3 arranged on the mounting base 1, an industrial computer 4 embedded in the left support base 2 or the right support base 3, a drum 5 rotatably arranged on the left support base 2 and the right support base 3, a first bearing seat 13 arranged on the left support base 2, a second bearing seat 19 arranged on the right support base 3, an air intake pipe 8 that runs through the first bearing seat 13 and has one end placed in the drum 5, a connecting pipe 21 that is rotatably sleeved on the second bearing seat 19 and has one end connected to the drum 5, a steam inlet pipe 7 and a vacuum pipe 22 that runs through the connecting pipe 21 and has one end placed in the drum 5, a dryer 12 connected to the air intake pipe 8, a motor 15 and a reducer 16 arranged on the right support base 3, a belt 17 arranged between the motor 15 and the reducer 16, a first gear 18 arranged on the reducer 16, and a second gear 20 sleeved on the connecting pipe 21 and meshingly connected to the first gear 18. The motor 15 is used to drive the first gear 18, the second gear 20, the connecting pipe 21 and the drum 5 to rotate. In this embodiment, the first bearing seat 13 and the second bearing seat 19 are rotatably connected to the drum 5. In addition, the air intake pipe 8, the steam intake pipe 7 and the vacuum pipe 22 are non-rotating parts, which are sealed and connected to the drum 5, and the air intake pipe 8, the steam intake pipe 7 and the vacuum pipe 22 are arranged on the rotation axis of the drum 5. In this embodiment, the objects to be dried are loaded into the drum 5 from the inlet and outlet cover plate 6. A filter cover 14 is arranged on the air intake pipe 8, and the filter cover 14 is arranged in the drum 5.

[0035] In this embodiment, the outside of the air inlet pipe 8 is connected to the first valve 9, the three-way pipe 10 and the second valve 11 in sequence, and the dryer 12 is connected to the lower part of the three-way pipe 10. In this embodiment, the dryer 12 includes a dryer upper connecting pipe 121 connected to the air inlet pipe 8, a molecular sieve storage cylinder 122 arranged at the lower part of the dryer upper connecting pipe 121 for storing a molecular sieve 127, an inner cup body 124 arranged at the lower part of the molecular sieve storage cylinder 122, an outer cup body 125 sleeved on the outside of the inner cup body 124, a plurality of air inlet U-shaped tubes 123 arranged in the molecular sieve storage cylinder 122, and a connecting pipe 126 arranged at the bottom of the inner cup body 124 and the inner wall of the outer cup body 125. Among them, a plurality of second meshes 1261 are opened on the edges around the connecting pipe 126. A plurality of connecting holes are arranged at the bottom of the inner wall of the molecular sieve storage cylinder 122, and the ends of the air inlet U-shaped tubes 123 are connected to the connecting holes one by one. Moreover, in this embodiment, a plurality of first meshes 1231 are provided on the air intake U-shaped tube 123. In the molecular sieve storage cylinder 122, the molecular sieve 127 submerges the air intake U-shaped tube 123, so that the air discharged from the first meshes 1231 is in full contact with the molecular sieve 127. In addition, in this embodiment, hydraulic oil or insulating oil is stored in the inner cup body 124 and the outer cup body 125 to filter impurities in the air, and the hydraulic oil or insulating oil just submerges the second meshes 1261.

[0036] During drying, the first valve 9 and the second valve 11 are both in a closed state, and the steam for drying is introduced through the steam inlet pipe 7, and the vacuum is drawn through the vacuum pipe 22. After drying, the first valve 9 is slowly opened, and the floating state of the hydraulic oil or insulating oil stored in the inner cup body 124 and the outer cup body 125 is observed, so that the hydraulic oil or insulating oil does not enter the molecular sieve storage cylinder 122. The air flow direction is Figure 6 In the direction of the arrow in the figure, air enters from all around the outer cup body 125, and drives the hydraulic oil or insulating oil to float, and the hydraulic oil or insulating oil is sucked into the inner cup body 124. Since the inner diameter of the inner cup body 124 is much larger than the diameter of the connecting pipe 126, the hydraulic oil or insulating oil only forms a layer of filtered liquid in the inner cup body 124, so that the air can pass through the filtered liquid layer, and the hydraulic oil or insulating oil falls again under the action of its own weight (its principle is the same as that of a water filter vacuum cleaner, such as: CN202920078U, CN101664290A, etc., and is also the same as the principle of an oil-immersed transformer respirator, which will not be repeated here). After passing through the hydraulic oil or insulating oil, the air enters the molecular sieve storage cylinder 122, and is fully dried by the molecular sieve 127 to absorb moisture in the air. The dried air enters the drum 5, slowly releases the vacuum, and effectively avoids the problem of external air entering and causing the dried object to absorb moisture in the air and condense water droplets.

[0037] The above embodiments are only preferred embodiments of the present utility model and are not intended to limit the protection scope of the present utility model. Any changes that adopt the design principles of the present utility model and are made through non-creative labor on this basis should fall within the protection scope of the present utility model.
