Description

Technical Field

[0001] This utility model relates to the field of pressure plate type wood vacuum drying technology, specifically a pressure plate type wood vacuum dryer. Background Technology

[0002] The pressure plate type vacuum wood dryer achieves rapid dehydration of wood through the synergistic effect of vacuum environment and pressurized heating. Its working principle is as follows: wood is stacked in a sealed drying chamber, and a vacuum pump reduces the air pressure inside the chamber, causing the moisture to boil and evaporate at a low temperature. Simultaneously, the pressure plate system applies uniform pressure to the wood, inhibiting drying deformation and enhancing heat transfer efficiency. Heating devices (such as electric heating plates or steam pipes) provide a stable heat source, and heat is directly transferred to the interior of the wood through the pressure plates, accelerating moisture migration. The evaporated water vapor is continuously discharged by the vacuum pump, and waste heat is recovered through a condenser, reducing energy consumption. During the drying process, the system monitors the wood's moisture content, temperature, and vacuum level in real time using sensors, dynamically adjusting the heating power and vacuum pressure to ensure uniform drying. This technology is particularly suitable for thick boards, hardwoods, and other difficult-to-dry woods, shortening the drying cycle while reducing defects such as cracking and warping, combining high efficiency and quality stability.

[0003] Vacuum pumps remove moisture by drawing away gas and lower the evaporation point, increasing the rate of moisture evaporation from the wood. However, because the vacuum pump can only remove a limited amount of gas, water vapor evaporated from the wood tends to accumulate inside the chamber during vacuum drying, leading to increased ambient humidity and inhibiting further evaporation of moisture from the wood. This problem is particularly pronounced in the later stages of drying, as the hardened layer on the material surface creates thermal resistance, hindering heat transfer and vapor release. Therefore, a device capable of separating water from the inside of the dryer under vacuum conditions is needed. Utility Model Content

A spring 508 is fixedly connected to one side of the baffle 507. A retaining ball 509 is fixedly connected to the upper end of the spring 508. The retaining ball 509 is located inside the baffle 507. A support rod 510 is fixedly connected inside the drying oven 2. A water tank 511 is fixedly connected to the lower end of the support rod 510. The water tank 511 is connected to the water transfer pipe 506.

[0028] Furthermore, the diameter of the ball stop 509 is smaller than the outer diameter of the baffle 507 and larger than the inner diameter of the baffle 507.

[0029] Furthermore, the water transfer pipe 506 is designed with a U-shaped structure.

[0030] Furthermore, the water transfer pipe 506 is designed with an L-shaped cross-section.

[0031] Example 2:

[0032] This mechanism is used to squeeze the water absorbed by the sponge 607, which increases the water discharge rate inside the drying chamber 2. (See also...) Figure 1-5Furthermore, in conjunction with Embodiment 1, the water squeezing mechanism 6 includes a support sleeve 601, which is fixedly connected to one side of the support plate 501. A motor 602 is fixedly connected inside the support sleeve 601, and a rotating rod 603 is fixedly connected to the output end of the motor 602. The rotating rod 603 is rotatably connected inside the support plate 501. A drive groove 604 is provided on the surface of the rotating rod 603. A squeezing slide cylinder 605 is slidably connected to the outer wall of the rotating rod 603. A pressure relief valve 606 is connected inside the squeezing slide cylinder 605. The squeezing slide cylinder 605 is slidably and sealed to one end of the support cylinder 502. The squeezing slide cylinder 605 is slidably and sealed to the outer wall of one end of the rotating rod 603. A sponge 607 is fixedly connected to one end of the squeezing slide cylinder 605. The sponge 607 is slidably connected inside the support cylinder 502. A drag rod 608 is rotatably connected to the inner wall of the squeezing slide cylinder 605. A sliding plate 609 is slidably connected inside the drive groove 604. The sliding plate 609 is fixedly connected to the drag rod 608.

[0033] Furthermore, the drive slot 604 is configured as a bidirectional helical slot with both ends connected.

[0034] Furthermore, the pressure relief valve 606 is connected to both ends of the compression slide 605.

[0035] In actual operation, when this device is used, the user opens the door of the drying chamber 2, then pushes the wood stack into the drying chamber 2 via the slide rail 4. The user then closes the door of the drying chamber 2 and starts the drying device. After preparation, the user starts the motor 602 and supplies cold air to the condenser tube 505. During the evaporation of water vapor from the wood, due to the rising steam and the condensation of moisture, the sponge 607 can quickly absorb the water droplets condensed on the outer wall of the condenser tube 505. The output of the motor 602 drives the rotating rod 603 to rotate. When the rotating rod 603 rotates, it causes the drive groove 604 to continuously push the sliding plate 609 through the inner wall, and the sliding plate 609 drives the extrusion... The slide 605 brings the sponge 607 to one end of the support cylinder 502. As the slide 605 moves, it squeezes the water out of the sponge 607 and sends it to the water tank 511 through the water transfer pipe 506. The water tank 511 can prevent the heat flow rate inside the drying chamber 2. The user can also choose to directly connect the water transfer pipe 506 to the outside of the drying chamber 2. Since the two ends of the drive groove 604 are connected, when the drive groove 604 drives the slide plate 609 to return, the inside of the support cylinder 502 is in a negative pressure state. The pressure relief valve 606 can be connected to balance the air pressure inside the drying chamber 2. The moisture inside the drying chamber 2 can be quickly discharged by the continuous reciprocating squeezing of the slide 605.
