Description

Technical Field

[0001] The utility model relates to the technical field of building gypsum drying, in particular to a dehumidifying drying machine for building gypsum. Background Art

[0002] During the production process of building gypsum products, a large amount of moisture will be contained. Only by removing the moisture can the strength and stability of building gypsum products be enhanced. Therefore, it is necessary to use drying equipment to dry it and accelerate the evaporation of moisture.

[0003] Existing building gypsum products include gypsum boards. When drying, the gypsum boards are generally placed on a support frame at equal intervals horizontally or vertically, and the support frame is pushed into a drying device for drying. The support frame is provided with horizontal support rods or support plates for supporting the horizontally arranged gypsum boards. Multiple gypsum boards are distributed vertically in the support frame. The gypsum boards are dried by hot air generated by the drying equipment. However, the contact portion between the lower surface of the horizontally placed gypsum board and the support rods or support plates is poorly dried, resulting in uneven drying inside the gypsum board, which can cause deformation of the gypsum board. Although vertically inserting the gypsum board into the support frame for drying can reduce the contact area between the gypsum board and the support frame, thereby increasing the drying area and drying effect, the vertically placed gypsum board containing a large amount of water will deform when placed vertically, affecting the production quality of the gypsum board. Utility Model Content

[0004] In order to solve the technical problems existing in the above background technology, the utility model provides a dehumidifying dryer for building gypsum.

[0005] The technical solution of this utility model is as follows:

[0006] A dehumidifying dryer for building gypsum includes a drying box body, a heating device and a hot air circulation device are provided on one side of the drying box body, a dehumidifying device is provided on the upper side, and a support frame for placing the building gypsum is also provided in the drying box body, the support frame includes a frame body and a plurality of transverse support frames arranged at intervals from bottom to top, the length direction of the transverse support frames is consistent with the length direction of the support frame, a plurality of rotating rollers are provided at intervals along the length direction of the transverse support frames, and the axes of the rotating rollers are perpendicular to the length direction of the transverse support frames;

[0007] At least one rotating roller in each transverse supporting frame can be driven to rotate by a driving unit arranged on one side of the frame body, and the rotating roller connected to the driving unit is an active roller.

[0008] Multiple gypsum boards can be placed horizontally in the support frame, and the gypsum boards can be quickly moved to the corresponding horizontal support frame by the rotating roller. The contact area between the rotating roller and the gypsum board is small, and the adjacent rotating rollers are arranged at intervals, which can increase the drying area of ​​the lower surface of the gypsum board and reduce the deformation of the gypsum board due to uneven drying. In order to facilitate better drying of the lower surface of the gypsum board, the gypsum board is set to be able to move in a smaller range in the horizontal support frame through the active rotation of the active roller, thereby exposing the contact position with the rotating roller and accelerating the overall drying effect of the gypsum board.

[0009] The specific structure of the above-mentioned driving unit is that the driving unit includes a driving motor and multiple gears corresponding to the active rollers. The gears are arranged at the end of the active roller and are coaxial with it. The output end of the driving motor is connected to the gear meshing transmission through a connecting component. The driving motor can drive the gear to rotate, and then drive the corresponding active roller to rotate. The starting time of the driving motor is set to a few seconds, which is enough to drive the active roller through the gear to stagger the contact point between the lower surface of the gypsum board and the rotating roller. Then the driving motor stops working to avoid transporting the gypsum board out of the horizontal support frame.

[0010] In order to facilitate synchronous control of the rotation of multiple active rollers at different heights, thereby driving the gypsum board in the support frame to move a small distance, the active rollers at different heights are located in the same vertical plane.

[0011] Regarding the structure of the connecting assembly, the connecting assembly includes a vertical heat insulation cover and a rack vertically slidably connected to one side thereof. The vertical heat insulation cover is vertically arranged on one side of the horizontal support frame. The gear is located inside the vertical heat insulation cover, and the rack is engaged with multiple gears at the same time.

[0012] The installation position of the above-mentioned driving motor is, and the connecting assembly also includes a coupling, and the driving motor is connected to one end of the active roller located at the bottom through the coupling.

[0013] In order to facilitate the rack to move up and down a certain distance in the vertical heat shield, the length of the rack is 5-20 cm shorter than the length of the vertical heat shield.

[0014] The installation structure of the rack in the vertical heat insulation cover is as follows: two parallel limit strips are provided along the length direction of the vertical heat insulation cover. The width of the two limit strips is adapted to the rack. The rack is slidably connected in the limit strips. The limit strips limit the rack in the horizontal direction, so that the rack can only move in the up and down directions.

[0015] Regarding the installation position of the gear, one end of the active roller connecting the gear passes through the transverse support frame, and the gear is located outside the transverse support frame, which is convenient for installing and disassembling the gear and connecting components outside the transverse support frame.

[0016] The beneficial effects of the present invention are:

[0017] The horizontal support frame and the active rollers and multiple rotating rollers therein can support the horizontally placed gypsum board, making it easier to place the gypsum board into the support frame, reducing wear on the support frame or the horizontal support frame, and making it easier to quickly take out and pack the dried gypsum board.

[0018] An active roller arranged in the same horizontal plane can be driven to rotate by a driving unit, so that when the gypsum board is dried in the drying box body, the driving unit drives the gypsum board to move in a small range horizontally along the transverse support frame, so that the contact positions of the gypsum board with the rotating roller and the active roller are staggered, so as to facilitate comprehensive drying of the lower surface of the gypsum board, ensure uniform drying of the lower surface of the gypsum board, and reduce deformation of the gypsum board;

[0019] The multiple active rollers arranged vertically are arranged on the same vertical plane, so that the gears on them are also located on the same vertical plane, so that multiple gears can be driven to rotate synchronously by a drive motor and a rack. This facilitates the simultaneous control of multiple gypsum boards in the support frame.

[0020] The active roller of the drive unit also facilitates the placement of the gypsum board in the support frame and the removal of the support frame. BRIEF DESCRIPTION OF THE DRAWINGS

The support frame includes a frame body 5 and a plurality of transverse support frames 6 arranged at intervals from bottom to top. The length direction of the transverse support frame 6 is consistent with the length direction of the support frame. A plurality of rotating rollers 7 are provided at intervals along the length direction of the transverse support frame 6.

[0033] See also Figure 3 、 Figure 4 and Figure 8 As shown, in this embodiment, each lateral support frame 6 is provided with a rotating roller 7 that can be driven to rotate by a drive unit provided on one side of the frame body 5. The rotating roller 7 connected to the drive unit is the active roller 8. To facilitate synchronous control of the rotation of multiple active rollers 8 at different heights, thereby driving the gypsum board within the support frame to move a small distance, the active rollers 8 at different heights are located in the same vertical plane, so that the multiple gears 9 are also located in the same vertical plane.

[0034] Multiple gypsum boards can be placed horizontally in the support frame, and the gypsum boards can be quickly moved to the corresponding horizontal support frame 6 by the rotating roller 7. The contact area between the rotating roller 7 and the gypsum board is small, and the adjacent rotating rollers 7 are arranged at intervals, which can increase the drying area of ​​the lower surface of the gypsum board and reduce the deformation of the gypsum board due to uneven drying. In order to facilitate better drying of the lower surface of the gypsum board, the gypsum board is arranged to be able to move in a smaller range in the horizontal support frame 6 through the active rotation of the active roller 8, so that the contact position with the rotating roller 7 is leaked and the overall drying effect of the gypsum board is accelerated; within a certain period of drying, the driving motor can be controlled to reverse and drive the active roller 8 to transport the gypsum board to the initial position or the preset position for further drying; the driving motor can also be controlled to rotate forward and reverse alternately to drive the gypsum board to move slowly back and forth, and the hot air blown out by the heating device 2 and the hot air circulation device 3 can be used to dry the gypsum board in all directions, thereby improving the drying efficiency and reducing the deformation of the gypsum board compared to the vertically arranged gypsum board.

[0035] See also Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the specific structure of the above-mentioned drive unit is that the drive unit includes a drive motor 10 and a plurality of gears 9 arranged corresponding to the active roller 8.

A protective cover 14 is provided on the outside of the drive motor 10 for heat insulation and protection. The gear 9 is arranged at the end of the active roller 8 and is coaxial with it. The output end of the drive motor 10 is meshed and connected with the gear 9 through a connecting component. The drive motor 10 can drive the gear 9 to rotate, and then drive the corresponding active roller 8 to rotate. The start time of the drive motor 10 is set to a few seconds, which is enough to drive the active roller 8 through the gear 9 to stagger the contact point between the lower surface of the gypsum board and the rotating roller 7. Then the drive motor 10 stops working to avoid transporting the gypsum board out of the horizontal support frame 6.

[0036] Regarding the installation position of the gear 9, one end of the active roller 8 connected to the gear 9 passes through the transverse support frame 6, and the gear 9 is located outside the transverse support frame 6, which is convenient for installing and disassembling the gear 9 and the connecting components outside the transverse support frame 6.

[0037] See also Figure 4 As shown, the connection assembly includes a coupling, a vertical heat shield 11, and a rack 13 vertically slidably connected to one side thereof. The vertical heat shield 11 protects the rack 13 and the gear 9. The vertical heat shield 11 is vertically mounted on one side of the horizontal support frame 6. The gear 9 is located within the vertical heat shield 11, and the rack 13 meshes with multiple gears 9 simultaneously. The drive motor 10 is connected to one end of the bottommost active roller 8 via a coupling.

[0038] To facilitate the vertical movement of the rack 13 within the vertical heat shield 11, the rack 13 is 5-20 cm shorter than the vertical heat shield 11. The rack 13 is mounted within the vertical heat shield 11 using two parallel limit bars 12 along its length. The width of the two limit bars 12 matches that of the rack 13. The rack 13 slides within the limit bars 12, which limit the rack 13 horizontally, limiting its vertical movement.
