Description

Technical Field

[0001] The utility model relates to the technical field of kiln furniture, in particular to a push plate and a conveying device for a push plate furnace. Background Art

[0002] As one of the auxiliary parts for the push plate kiln, the commonly used traditional push plate is a horizontal surface. The push plate and the sagger placed on the push plate surface are not fixed. During the pushing process of the push plate and the sagger on the conveyor belt, the vibration caused by the conveying or uneven platform will cause the push plate and the sagger to shift, resulting in the push plate and the sagger being separated from the conveyor belt during the pushing process, causing the loss of equipment or materials. In addition, since the push plate surface is horizontal, the contact area between the push plate and the bottom of the sagger is large. During the high-temperature sintering process, the heat dissipation and heating of the bottom of the sagger are uneven, resulting in a decrease in the sagger bottom sintering effect.

[0020] The technical solution of the utility model is further described in detail below through the accompanying drawings and embodiments.

[0021] Example 1

[0022] Figure 1 , Figure 2 The schematic diagram of the structure and the schematic diagram of the cross section of a push plate for a push plate furnace provided in the embodiment of the utility model are respectively Figure 1 and Figure 2 As shown, a push plate 10 for a push plate furnace provided by the embodiment of the utility model includes a push plate base 101, and a groove 102 suitable for the bottom of the sagger is provided on the push plate base 101. The stability of the sagger during the conveying process is ensured by the design of the groove 102. A plurality of trapezoidal bosses 103 are arranged in the groove 102, and the upper surface of the trapezoidal bosses 103 is lower than the upper surface of the push plate base 101. The sagger is arranged on the trapezoidal bosses 103. It can be understood that the bottom of the sagger is in contact with only the upper surface of the trapezoidal bosses 103, and the contact area is small. In this way, during the pushing and sintering process, the design of the trapezoidal bosses 103 can provide a smooth atmosphere and good heating conditions for the bottom of the sagger, so that the sagger is heated more evenly.

[0023] It should be noted that those skilled in the art can design the depth and edge thickness of the groove 102 according to the size of the sagger. In this example, the depth of the groove 102 is preferably 3mm-30mm, and the edge thickness of the groove 102 is preferably 5mm-30mm to ensure the stability of the sagger during transmission.

[0024] Furthermore, those skilled in the art can set the height of the trapezoidal boss 103, the width ratio of the upper and lower platforms of the trapezoidal boss 103, and the number according to heating requirements. In this example, the height of the trapezoidal boss 103 is preferably 1mm-20mm, the width ratio of the upper and lower platforms of the trapezoidal boss 103 is 1:(1-3), the trapezoid is preferably an isosceles trapezoid, the sagger is placed with uniform force, and the number of the trapezoidal bosses 103 is preferably 3-6 to ensure the stability of the sagger placement.

[0025] In some embodiments, in order to ensure the stability of the push plate during the sintering process, the push plate is preferably made of one or more of corundum, alumina, and mullite.

[0026] The push plate for a push plate furnace provided by the embodiment of the utility model has a good stabilizing effect on the sagger, and can provide an unobstructed atmosphere and a good heating condition for the bottom of the sagger during the pushing and sintering process, so that the sagger is heated more evenly.

[0030] The conveying support 20 is used to support the conveying equipment.

[0031] The conveying roller 30 is used for conveying the push plate 10. Specifically, a plurality of conveying rollers 30 are provided on the conveying bracket 20, and the push plate 10 is placed above the conveying rollers 30. The friction between the push plate 10 and the conveying bracket 20 is reduced by adding the conveying rollers 30, thereby avoiding the displacement of the sagger and the push plate 10 caused by the vibration caused by the conveying or the uneven platform during the pushing process, and avoiding the phenomenon of the push plate 10 and the sagger being separated during the pushing process.

[0032] Two fixed pulleys 40 are used to fix the push plate 10 during the conveying process. Specifically, fixed pulleys 40 are respectively provided on both sides of the conveying bracket 20, and the push plate is located between the two fixed pulleys 40. During the conveying process, the conveying roller 30 rolls to drive the push plate 10 to move and convey on the conveying roller 30. The two fixed pulleys 40 limit the push plate, thereby further avoiding the displacement and separation of the push plate 10 and the sagger during the pushing process.

[0033] In some embodiments, two fixed pulleys 40 can be symmetrically arranged on both sides of the transmission bracket 20, and the distance between the two fixed pulleys 40 is greater than the width of the push plate 10, so that the placement of the push plate 10 is convenient and the transmission process is stable. In this example, the difference between the distance between the two fixed pulleys 40 and the width of the push plate 10 is preferably 5mm-30mm. It can be understood that those skilled in the art can set the distance between the push plate 10 and the fixed pulley 40 according to the size of the push plate 10 and actual needs to ensure stability during the transmission process.

[0034] In some embodiments, the two fixed pulleys 40 may also be staggered on both sides of the conveying bracket 20 to ensure the stability of the push plate 10 at different conveying positions during the conveying process.

[0035] The utility model provides a conveying device for a push plate furnace, which fixes the sagger by means of grooves on the surface of the push plate, fixes the push plate by pulleys on both sides of the conveying bracket, and reduces the friction between the push plate and the conveying device by adding a conveying roller, thereby ensuring the stability of the push plate during the transmission process and avoiding the displacement and separation of the sagger and the push plate due to vibration caused by transmission or uneven platform.
