Description

Technical Field

[0001] The utility model relates to the technical field of drying kilns, in particular to a drying kiln with controllable heat dissipation for producing refractory materials. Background Art

[0002] The drying kiln used in the production of refractory materials is one of the key equipment in the production process of refractory materials. It is mainly used to dry the bricks after the refractory materials are formed to reduce their moisture content. The design and type of the drying kiln can be determined according to factors such as the characteristics of the processed materials, product requirements and energy conditions. Most of the existing drying kilns cannot achieve automatic temperature control, which affects the drying efficiency and quality of the objects.

[0003] In order to address the above problems, the Chinese patent with the existing announcement number CN214746812U proposes a new type of high-efficiency automatic temperature-controlled drying kiln. The device drives the shaft rotating rod through a bidirectional motor, so that the rotating rod drives the first bevel gear to rotate, and the first bevel gear drives the second bevel gear to rotate, thereby driving the fan to rotate, so that the fan exhausts and dissipates heat to the drying chamber and the heating chamber, thereby achieving temperature control inside the kiln body.

[0004] However, although the above-mentioned new type of high-efficiency automatic temperature-controlled drying kiln can exhaust and dissipate heat from the drying chamber and the heating chamber by turning on the fan in the exhaust pipe to achieve temperature control inside the kiln body, the fan position in the new type of high-efficiency automatic temperature-controlled drying kiln is fixed, which makes the wind flow generated by the fan unable to quickly dissipate heat from the drying chamber and the heating chamber. Therefore, the utility model provides a drying kiln with controllable heat dissipation for refractory material production to meet the demand. Utility Model Content

[0009] A kiln body, wherein a fixing part is fixedly connected at its opening through a support plate, the fixing part is penetrated with a through hole arranged opposite to the opening of the kiln body, a lifting rod which can slide to the inside of the kiln body is slidably connected in the through hole, a rack is arranged along the length direction of the lifting rod, a gear meshing with the rack is rotatably connected in the through hole through a rotating shaft, and the rotating shaft is driven by a motor;

[0010] A lifting plate is fixedly connected to the bottom of the lifting rod, a plurality of exhaust ports are penetrated on the lifting plate, an exhaust passage connected to the plurality of exhaust ports is provided inside the lifting plate, an air intake passage connected to the exhaust passage is penetrated inside the lifting rod, and a blower connected to the air intake passage is provided on the top of the lifting rod.

[0011] Preferably, sliders are relatively fixedly connected to both sides of the lifting rod, and the fixing portion is provided with a sliding groove for the sliders to slide.

[0012] Preferably, a placing plate is fixedly connected to the inner wall of the kiln body relative to the lifting plate, and the placing plate is suitable for placing refractory materials.

[0013] Preferably, a heat dissipation port is penetrated on the side of the kiln body away from the rotation direction of the motor, a shielding plate for shielding the heat dissipation port is movably provided on the kiln body, a movable groove for the shielding plate to move is provided in the kiln body, and the movable groove is connected to the heat dissipation port.

[0014] Preferably, the orthographic projection area of ​​the heat dissipation opening is smaller than the orthographic projection area of ​​the shielding plate.

[0015] Preferably, a traction wheel is sleeved on the rotating shaft, a traction rope is sleeved on the traction wheel, and one end of the traction rope away from the traction wheel is fixedly connected to the shielding plate.

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] In the above scheme, a lifting rod, a rack, a gear, and an exhaust port are provided, and the exhaust port is driven by the lifting rod to move up and down along the kiln body, so that the wind flow generated by the blower can quickly occupy the inside of the kiln body, increase the contact area between the equipment inside the kiln body and the wind flow, thereby accelerating the heat dissipation efficiency inside the kiln body.

[0018] In the above scheme, by providing a slider and a slide groove, the provision of the slider and the slide groove facilitates improving the stability of the lifting rod sliding along the fixed portion, thereby avoiding the lifting rod from tilting.

[0019] In the above scheme, by setting a traction wheel, a baffle, a heat dissipation port, and a traction rope, when the motor drives the lifting rod to move toward the inside of the kiln body for heat dissipation, the rotating shaft drives the traction wheel to rotate, the traction wheel pulls and wraps the traction rope, and the traction rope pulls the baffle plate up, so that the baffle plate no longer blocks the heat dissipation port, thereby accelerating the heat dissipation efficiency inside the kiln body.

DETAILED DESCRIPTION

[0029] like Figures 1 to 6As shown, an embodiment of the utility model provides a drying kiln with controllable heat dissipation for refractory material production, comprising a kiln body 1, an opening of which is fixedly connected to a fixing portion 4 via a support plate 3, the fixing portion 4 is penetrated with a through hole 22 arranged opposite to the opening of the kiln body 1, a lifting rod 6 which is slidably connected in the through hole 22 and can slide into the inside of the kiln body 1, a rack 19 is provided along the length direction of the lifting rod 6, a gear 12 which is rotatably connected in the through hole 22 and meshes with the rack 19 via a rotating shaft 13, and the rotating shaft 13 is driven by a motor 7; a lifting plate 10, which is fixedly connected to the bottom of the lifting rod 6, a plurality of exhaust ports 14 are penetrated in the lifting plate 10, an exhaust channel 21 connected to the plurality of exhaust ports 14 is provided inside the lifting plate 10, an air inlet channel 20 connected to the exhaust channel 21 is penetrated inside the lifting rod 6, and a blower 5 connected to the air inlet channel 20 is provided at the top of the lifting rod 6.

[0030] Specifically, when the inside of the kiln body 1 needs to be heat-dissipated, the motor 7 drives the gear 12 to rotate, and the gear 12 drives the rack 19 to move, thereby driving the lifting rod 6 and the lifting plate 10 to move toward the inside of the kiln body 1, and at the same time starting the blower 5, so that the blower 5 discharges the wind flow to the air inlet channel 20 and the exhaust channel 21, and then discharges it to the inside of the kiln body 1 along the exhaust port 14. Since the lifting rod 6 moves slowly toward the bottom of the kiln body 1, the wind flow from the exhaust port 14 can blow to each position of the kiln body 1, increasing the contact area between the equipment inside the kiln body 1 and the wind flow, thereby accelerating the heat dissipation effect inside the kiln body 1. The problem that the fan position in the existing drying kiln is fixed, so that the wind flow generated by the fan cannot quickly dissipate heat to the drying chamber and the heating chamber, resulting in low heat dissipation efficiency, should be explained. The motor 7 is a motor 7 that can be reversed, specifically a three-phase motor 7, a stepper motor 7, etc. At the same time, the moving direction of the lifting rod 6 is toward the inside of the kiln body 1, and the length of the lifting plate 10 is less than the diameter of the opening of the kiln body 1, so as to ensure that the lifting plate 10 can be moved out along the opening of the kiln body 1, so as to facilitate the sealing of the opening of the kiln body 1 when the kiln body 1 needs to be used, thereby ensuring the normal operation of the device.

[0031] like Figure 4 and Figure 6 As shown, in this embodiment, sliders 15 are relatively fixedly connected on both sides of the lifting rod 6, and a sliding groove 16 is provided on the fixed part 4 for the slider 15 to slide. Specifically, the arrangement of the slider 15 and the sliding groove 16 facilitates improving the stability of the lifting rod 6 sliding along the fixed part 4 and avoiding the lifting rod 6 from tilting.

[0032] like Figure 2 As shown, in this embodiment, a placement plate 9 is fixedly connected to the inner wall of the kiln body 1 relative to the lifting plate 10, and the placement plate 9 is suitable for placing refractory materials.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in this embodiment, a heat dissipation port 18 is provided on the side of the kiln body 1 away from the rotation direction of the motor 7, a shielding plate 2 for shielding the heat dissipation port 18 is movably provided on the kiln body 1, a movable groove 17 for the shielding plate 2 to move is provided in the kiln body 1, the movable groove 17 is communicated with the heat dissipation port 18, the orthographic projection area of ​​the heat dissipation port 18 is smaller than the orthographic projection area of ​​the shielding plate 2, a traction wheel 8 is sleeved on the rotating shaft 13, a traction rope 11 is sleeved on the traction wheel 8, and the end of the traction rope 11 away from the traction wheel 8 is fixedly connected to the shielding plate 2. Specifically, when the motor 7 rotates, the kiln body 1 is provided with a traction wheel 8, and the traction wheel 8 is provided with a traction rope 11. The traction rope 11 is fixedly connected to the shielding plate 2 at one end. When the motor 7 drives the lifting rod 6 to move toward the inside of the kiln body 1 for heat dissipation, the rotating shaft 13 drives the traction wheel 8 to rotate, the traction wheel 8 pulls and winds the traction rope 11, and the traction rope 11 pulls the baffle plate 2 to rise, so that the baffle plate 2 no longer blocks the heat dissipation port 18, thereby accelerating the heat dissipation efficiency inside the kiln body 1. Similarly, when the motor 7 drives the lifting rod 6 to rise, the traction wheel 8 rotates in the opposite direction, and drives the traction rope 11 to reset under the gravity of the baffle plate 2 itself, that is, the heat dissipation port 18 is blocked again, thereby ensuring the normal use of the kiln body 1.

[0034] Working principle:

[0035] When it is necessary to perform heat dissipation treatment on the inside of the kiln body 1, the gear 12 is driven to rotate by the motor 7, and the gear 12 drives the rack 19 to move, thereby driving the lifting rod 6 and the lifting plate 10 to move toward the inside of the kiln body 1, and at the same time, the rotating shaft 13 drives the traction wheel 8 to rotate, and the traction wheel 8 pulls and winds the traction rope 11, and the traction rope 11 pulls the shielding plate 2 up, so that the shielding plate 2 no longer blocks the heat dissipation port 18, thereby accelerating the heat dissipation efficiency inside the kiln body 1. At this time, the blower 5 is started, so that the blower 5 discharges the wind flow to the air inlet channel 20 and the exhaust channel 21, and then discharges it to the inside of the kiln body 1 along the exhaust port 14. Since the lifting rod 6 moves slowly toward the bottom of the kiln body 1, the wind flow of the exhaust port 14 can blow to each position of the kiln body 1, increasing the contact area between the internal equipment of the kiln body 1 and the wind flow, thereby accelerating the heat dissipation efficiency inside the kiln body 1, and solving the problem that the fan position in the existing drying kiln is fixed, so that the wind flow generated by the fan cannot quickly dissipate the heat in the drying chamber and the heating chamber, resulting in low heat dissipation efficiency.
