Description

Continuous vacuum dehumidification drying device

Technical Field

The invention relates to the technical field of drying equipment, in particular to a continuous vacuum dehumidifying and drying device.

Background

The drying is a technological process with high energy consumption, and the used energy accounts for about 12 percent of the total energy consumption of national economy. With the increasing exhaustion of fossil fuel resources and the strict requirements of low carbon and environmental protection, the drying energy consumption is reduced, and the energy-saving drying equipment is popularized.

At present, a drying device usually adopts several heat source forms such as electric heat, a heat pump and solar energy, a drying system usually adopts an open system, namely high-temperature and high-humidity air generated after drying is discharged outdoors, and meanwhile, a circulating drying mode of introducing fresh air is carried out, so that the process causes great energy waste because the high-temperature and high-humidity air is discharged.

In order to solve the problems, the closed drying system can effectively avoid the energy waste problem caused by the discharge of high-temperature air, the common dehumidification mode of the closed system is mainly cooling dehumidification and adsorption dehumidification, the cooling dehumidification needs to cool the high-temperature air to the dew point temperature to separate out moisture, and the repeated cooling and warming operation causes great energy waste. The adsorption dehumidification is to remove water vapor in the drying device by adsorption with an adsorbent. However, since the adsorbent is saturated, regeneration, i.e., separation from water vapor, is required. The regeneration mode commonly used at present is heating regeneration, but the heating regeneration needs 100 ℃ or even higher temperature, so that the energy can not be saved, and larger energy waste can be caused. In addition, the excessive heating temperature can promote the adhesion phenomenon of the adsorbent, so that the adsorbent is denatured and damaged and cannot be reused.

The positioning rod 56 is then pulled downward and the first link plate 54 is rotated so that the rod end of the wing rod of the positioning rod 56 is inserted into the second insertion hole 542. Then the third front rotating shaft 631 or the third rear rotating shaft 641 is rotated to realize the flipping. The front sliding frame body 12 and the rear sliding frame body 13 are then pushed inward, respectively, and the first front end cap 21, the first rear end cap 22, the second front end cap 23, and the second rear end cap 24 are locked. The third link plate 69 is then flipped over to disengage the second link shaft 68 from the recess 664, and the flip drive plate 61 is disengaged from the engagement plate 313 under the force of the third spring 65. The positioning rod 56 is then pulled downward and the first connecting plate 54 is rotated so that the rod ends of the wing rods of the positioning rod 56 are inserted into the first insertion holes 541.

Example two

The fixed frame body 11 is provided with a driving motor 51, and a power output shaft of the driving motor 51 is connected with the first front rotating shaft 211 through a transmission mechanism. Preferably, a driving gear is fixedly disposed on a power output shaft of the driving motor 51, a driven gear is fixedly disposed on the first front rotating shaft 211, and a width of the driving gear is larger than that of the driven gear, that is, in a process that the first front rotating shaft 211 slides back and forth along the front sliding frame 12, the driven gear is always engaged with the driving gear.

The rest of the structure is the same as the first embodiment.
