Description

Technical Field

[0001] The utility model relates to the technical field of roller kilns, in particular to a roller kiln replacement chamber with a transverse conveying function and a roller kiln. Background Art

[0002] The roller conveyor that transports the sagger to the replacement chamber may need to turn due to terrain restrictions. In the prior art, a common solution is to add a curved track outside the entrance of the replacement chamber. This solution greatly increases the floor space of the replacement chamber, and the conveying speed needs to be reduced when the sagger passes through the curve to prevent the sagger from slipping.

[0003] At the same time, in order to ensure airtightness, the curved part needs to be covered with a sealing shell. The sealing shell and the displacement chamber are connected by a bolt structure. When connected through an external structure, there will always be defects in airtightness, and the additional shell will also affect the buffering when the furnace expands. Utility Model Content

[0004] In order to overcome the defects in the prior art, the utility model provides a roller kiln replacement chamber and a roller kiln with a transverse conveying function. The roller kiln replacement chamber is provided with a feeding cavity for setting a transverse conveying mechanism, and no external sealing shell is required to ensure the air tightness of the device.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a roller kiln replacement chamber with a transverse conveying function, the roller kiln replacement chamber is divided into a feeding cavity and at least one working cavity by a plurality of sealed doors, the feeding cavity and the working cavity are both provided with conveying rollers, the conveying rollers are used to convey the saggers through each cavity in sequence, a transverse conveying mechanism is provided in the feeding cavity, the transverse conveying mechanism includes a transverse conveying roller for conveying the saggers along a first direction, and a turning roller for conveying the saggers to the conveying roller, the height of the transverse conveying roller is lower than the conveying roller, the turning roller is connected to a lifting mechanism, the lifting mechanism can lift the turning roller from below the transverse conveying roller to be flush with the conveying roller, thereby conveying the saggers to the conveying roller.

[0006] Through the above technical solution, the transverse conveying mechanism is arranged in the reserved feeding cavity in the roller kiln replacement chamber, and no external sealing shell is required, thereby ensuring the overall air tightness of the device. In addition, the design of the transverse conveying mechanism solves the problem of space occupation by the bend.

[0007] Furthermore, a track wheel is connected to the bottom of the roller kiln replacement chamber, and the track wheel is used to support the roller kiln replacement chamber, and the track wheel is arranged perpendicular to the kiln inlet direction. When the kiln expands, the track wheel supports the roller kiln replacement chamber to move relative to the kiln to buffer the expansion.

[0008] Furthermore, the transverse conveying roller includes two rows of rollers arranged opposite to each other, the rollers are driven by a motor, and a gap is left between the two rows of rollers for the steering roller to be raised and lowered.

[0009] Furthermore, the steering roller table includes a base and a plurality of rollers, the rollers are rotatably connected to the base, and the lifting mechanism includes a lifting cylinder, and a driving end of the lifting cylinder is connected to the base.

[0010] Initially, the steering roller is located below the transverse conveying roller. When the transverse conveying roller transports the sagger to a preset position, the lifting cylinder is actuated to lift the steering roller from below the transverse conveying roller. During the rising process, the steering roller lifts the sagger to be flush with the conveying roller and transports the sagger to the conveying roller.

[0011] Furthermore, the base is connected to at least two vertically arranged upright poles, the upright poles are used to position the sagger conveyed by the transverse conveying roller, and the upright poles are sleeved with a rotating wheel that rotates in the horizontal direction. When the transverse conveying roller conveys the sagger to a preset position, the baffle can position the sagger, making it convenient for the subsequent turning roller to lift up the sagger.

[0012] Furthermore, the base is connected to a guide mechanism, which includes a fixed linear bearing and a guide shaft passing through the linear bearing and connected to the base, and the linear bearing is vertically arranged. The guide mechanism ensures that the steering roller table rises and falls in the vertical direction.

[0013] Furthermore, the roller kiln replacement chamber is divided into a replacement chamber connected to the feeding chamber, a transition chamber connected to the replacement chamber, and a connecting chamber connected to the transition chamber, wherein the connecting chamber is connected to the kiln.

[0014] A roller kiln comprises the roller kiln replacement chamber with the horizontal conveying function and a roller kiln body connected to the roller kiln replacement chamber with the horizontal conveying function.

[0015] Furthermore, the conveying roller is provided in the roller kiln.

[0016] Furthermore, the working chamber at least includes a connecting chamber connected to the roller kiln and a replacement chamber connected to the feeding chamber, and the transverse conveying mechanism transports the sagger to the conveying roller of the replacement chamber, and the conveying roller transports the sagger through each working chamber in sequence until the sagger is transported into the roller kiln.

[0017] By means of the above technical solution, the beneficial effects of the utility model are as follows:

[0018] 1. The present application reserves a feeding cavity in the roller kiln replacement chamber, and arranges a transverse conveying mechanism in the feeding cavity, so that there is no need to connect an external bend and a sealing shell at the entrance of the roller kiln replacement chamber, thereby minimizing the volume of the roller kiln replacement chamber while ensuring good air tightness;

[0019] 2. The present application connects track wheels perpendicular to the kiln inlet direction at the bottom of the roller kiln replacement chamber. When the kiln expands, the track wheels support the roller kiln replacement chamber to move relative to the kiln to buffer the expansion.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] It should be noted that in the description of the present invention, the terms "first", "second", etc. are only used for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, and they cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0027] Example: Combination Figure 1-2 As shown, the first embodiment of the present invention discloses a roller kiln replacement chamber with a transverse conveying function, including a roller kiln replacement chamber 1 body, wherein the roller kiln replacement chamber 1 is divided into a feed cavity 12, a replacement cavity 13 connected to the feed cavity 12, a transition cavity 14 connected to the replacement cavity 13, and a connection cavity 15 connected to the transition cavity 14 by three sealing doors 11, wherein the connection cavity 15 is connected to the kiln. The feed cavity 12, the replacement cavity 13, the transition cavity 14 and the connection cavity 15 are all provided with a conveying roller 16, and the conveying roller 16 is used to sequentially convey the sagger in the feed cavity 12 through the feed cavity 12, the replacement cavity 13, the transition cavity 14 and the connection cavity 15. The sealing door 11 can completely separate two adjacent cavities to ensure the airtightness of the cavity when working.

[0028] A transverse conveying mechanism 2 is provided in the feeding cavity 12, and the transverse conveying mechanism 2 includes a transverse conveying roller for conveying the sagger along a first direction, the first direction being the direction in which the roller needs to turn due to the terrain or other factors, and the height of the transverse conveying roller is lower than the conveying roller 16, and the transverse conveying roller includes two rows of rollers 21 arranged opposite to each other, and the two rows of rollers 21 are connected to the same motor, and all rollers 21 are driven to rotate by the same motor to ensure that their rotation speeds are consistent, and to avoid speed differences between different rollers 21 causing the sagger to fall. A gap is reserved between the two rows of rollers 21, and the gap can be used for the steering roller to rise and fall therein. At the same time, the gap needs to be less than or equal to the length of the sagger to ensure that the sagger can be placed on the transverse conveying roller.

[0029] The steering roller conveys the sagger along the transport direction of the conveying roller 16 to convey the sagger to the conveying roller 16. The steering roller comprises a base 22 and a plurality of rollers 23. The rollers 22 and the base 22 are rotatably connected. The base 22 is connected with a lifting mechanism. The lifting mechanism comprises a lifting cylinder 24. The driving end of the lifting cylinder 24 is connected to the base 22. In this embodiment, a support platform 25 is further provided in the feeding cavity 12. The support platform 25 is used to raise the lifting cylinder 24 so that the height of the lifting cylinder 24 satisfies the requirement of raising the steering roller to be flush with the conveying roller 16.

[0030] The base 22 is also provided with a baffle 26 , which includes a plurality of vertically arranged upright poles, and a rotating wheel is rotatably provided on the upright poles.

[0031] Initially, the steering roller is located below the upper edge of the transverse conveying roller and the baffle 26 is located above the upper edge of the transverse conveying roller. The transverse conveying roller conveys the sagger along the first direction to the upper side of the steering roller and is blocked and positioned by the baffle 26. The lifting cylinder 24 is actuated to lift the steering roller from the lower side of the transverse conveying roller. During the rising process, the steering roller receives the sagger and lifts it to be flush with the conveying roller 16. The rod 22 of the steering roller rotates to transport the sagger to the conveying roller 16. In the process of the steering roller conveying the sagger to the conveying roller 16, the rotating wheel of the baffle 26 can reduce the friction between the sagger and the baffle 26.

[0032] Through the above technical solution, the roller kiln replacement chamber 1 is reserved with the feeding cavity 12 for installing the transverse conveying mechanism 2, and there is no need to connect a sealing shell separately, that is, the shell of the roller kiln replacement chamber 1 can be integrally formed to ensure its airtightness. At the same time, the turning roller of the transverse conveying mechanism 2 adopts a lifting design. Compared with the curved design in the prior art, the transverse conveying mechanism 2 provided in this embodiment occupies less space, thereby reducing the footprint of the overall device.

[0033] Four lightweight and high-strength crawler wheels 17 are connected to the bottom of the roller kiln replacement chamber 1. The crawler wheels 17 are used to support the roller kiln replacement chamber 1. The crawler wheels 17 are arranged perpendicular to the kiln inlet direction. When the kiln expands, the crawler wheels 17 support the roller kiln replacement chamber to move relative to the kiln to buffer the expansion.

[0034] It should be noted that the track wheel 17 can be replaced by other rollers with high supporting strength, such as a plurality of parallel tires.

[0035] In another feasible embodiment, the base 23 is connected to a guide mechanism (not shown in the figure), the guide mechanism includes a fixed linear bearing and a guide shaft passing through the linear bearing and connected to the base, the linear bearing is vertically arranged. The guide mechanism ensures that the steering roller is lifted and lowered in the vertical direction.

[0036] In another feasible embodiment, the guide mechanism includes two tracks extending in the vertical direction, and the two tracks are symmetrically arranged on both sides of the lifting cylinder 24. The driving end of the lifting cylinder 24 is connected to the track through a slider to ensure that the movement trajectory of the lifting cylinder 24 always remains vertical, thereby preventing the lifting cylinder 24 from tilting during the process of lifting the sagger, causing the sagger to slip and be damaged.

[0037] Embodiment 2 discloses a roller kiln, which adopts the above-mentioned roller kiln replacement chamber with horizontal conveying function.

[0038] The present invention uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
