Description

Technical Field

[0001] The invention relates to the technical field of baking oven structures, in particular to a vertical baking oven. Background Art

[0002] Baking ovens mainly use the heat energy generated by heating elements to bake food, tea leaves, etc. by heat conduction and heat radiation, so that they mature, set their shapes, and give the food a specific color and aroma. According to different heat sources, baking ovens can be divided into electric baking ovens, gas baking ovens, natural gas baking ovens and oil baking ovens; according to different uses and structures, they can be divided into small household baking ovens, large commercial baking ovens, flat ovens, hot air rotary ovens and other types.

[0003] The existing three-dimensional baking oven cannot automatically flip the material to be dried inside it, resulting in the bottom of the material to be dried directly contacting the hot air, making the drying effect at the bottom inconsistent with that at the top. When the material to be dried needs to be flipped, the baking oven needs to be opened for flipping, which is inconvenient, time-consuming and laborious to operate, and easily leads to heat loss.

[0004] For this purpose, we propose a vertical baking oven. Summary of the invention

[0007] When the second rotating disk rotates half a circle, the plug-in plate is automatically plugged into the second rotating disk, so that the first rotating disk rotates with the second rotating disk, thereby causing the mesh plates that cooperate with each other to flip and switch positions;

[0008] During the other half rotation of the second turntable, the plug plate is moved away from the second turntable, so that the first turntable maintains its position, and the second turntable rotates by itself to drive the movable part, thereby moving the screen plates away from each other.

[0016] Preferably, a limiting groove slidably matched with the movable plate is provided on the movable frame, and the side of the movable plate slidably matches with the inner wall of the movable frame.

[0017] Preferably, a cover plate is provided above the baking furnace body, and the gas pipe on the cover plate corresponds to the feed port to ensure the circulation of hot air.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 11 The present invention provides a vertical baking furnace, including a combustion chamber 1 and a baking furnace body 2 connected by a gas channel, and a feed port is arranged above the baking furnace body 2; it also includes a plurality of screen plates 3 that cooperate with each other and movable parts that cooperate with the screen plates 3, a first turntable 4 rotates on the inner wall of the baking furnace body 2, a second turntable 5 that rotates in the first turntable 4 and cooperates with the movable parts, a plug-in plate 6 is slidably matched on the first turntable 4, and during the process of the second turntable 5 rotating half a circle, the plug-in plate 6 is automatically plugged into the second turntable 5, so that the first turntable 4 rotates with the second turntable 5, so that the screen plates 3 that cooperate with each other are flipped and switched, and during the process of the second turntable 5 rotating another half a circle, the plug-in plate 6 is away from the second turntable 5, so that the first turntable 4 maintains its position, and the second turntable 5 rotates to drive the movable parts, so that the screen plates 3 are away from each other.

[0035] In the present application, the hot gas generated by the combustion of the solid material in the combustion chamber 1 enters the baking furnace body 2 through the gas channel and passes through the screen plate 3, thereby baking the material to be dried on the screen plate 3;

[0036] During the half-turn of the second turntable 5, the plug-in plate 6 is plugged and fixed on the second turntable 5 through the action of the matching piece, so that the first turntable 4 rotates with the second turntable 5 through the cooperation of the plug-in plate 6. At this time, the movable plate 9 rotates synchronously with the first turntable 4, and the movable plate 9 does not rotate relative to the first turntable 4, thereby driving the two fitted screen plates 3 to rotate, so that the screen plate 3 located at the bottom is replaced to the top, and the screen plate 3 located at the top is replaced to the bottom, so that the materials to be dried in the screen plates 3 are turned over, so that both sides of the materials to be dried can be baked by hot air;

[0037] During the other half circle when the second turntable 5 continues to rotate, the plug-in plate 6 is moved away from the second turntable 5 through the action of the matching parts, thereby not affecting the first turntable 4. The first turntable 4 remains stable and does not rotate. At this time, the movable plate 9 cannot rotate. Under the action of the movable parts and the second turntable 5, the two movable plates 9 slide along the first turntable 4, thereby making the two replaced screen plates 3 move away from each other, which is convenient for adjusting the distance between the screen plate 3 and the hot gas outlet of the gas channel.

[0038] The ends of the two upper and lower matching screen plates 3 are fixedly connected with multiple first retaining rings 7 and multiple second retaining rings 8, and the first retaining rings 7 and the second retaining rings 8 are staggered and plug-in distributed. When the two screen plates 3 are attached to each other and turned over, the first retaining rings 7 and the second retaining rings 8 are plug-in and matched with each other, and the first retaining rings 7 and the second retaining rings 8 are movably matched to ensure that the materials to be dried in the two screen plates 3 that are shaking against each other will not fall out of the screen plates 3.

[0039] The movable part includes a movable plate 9 meshing with the second turntable 5, a movable groove 10 slidingly matched with the movable plate 9 is provided on the first turntable 4, a connecting plate 11 passing through the movable groove 10 is provided on the movable plate 9, and the connecting plate 11 is connected and fixed to the screen plate 3 through a connecting rod, and a power part driving the second turntable 5 to rotate is provided on the baking furnace body 2;

[0040] The second turntable 5 is rotated by the power member. During the other half of the rotation of the second turntable 5, the first turntable 4 is stationary, and the movable groove 10 is in a vertical state. The movable plate 9 can only move in the vertical direction along the movable groove 10. The second turntable 5 rotates relative to the first turntable 4, so that the two movable plates 9 move along the movable groove 10. The moving directions of the two movable grooves 10 are opposite, so that the two connecting plates 11 drive the two screen plates 3 to move away from or close to each other.

[0041] The second rotating disk 5 is preferably a gear, and the movable plate 9 is preferably a toothed plate, which facilitates smooth meshing and stabilization.

[0042] It is worth noting that the connecting rod and the screen plate 3 are detachably connected and fixed, so that the material to be dried can be placed between the two screen plates 3, that is, by removing the upper screen plate 3 and placing the material to be dried on the lower screen plate 3, and finally installing and fixing the upper screen plate 3.

[0043] The connecting plate 11 is movably plugged into and matched with the movable plate 9. A pressing cylinder 12 in the shape of a truncated cone is provided in the middle of the first turntable 4 and is connected and fixed to the baking furnace body 2. A plurality of contact strips 13 that are pressed and matched with the connecting plate 11 are fixedly connected to the pressing cylinder 12. The two connecting plates 11 are close to each other under the action of the movable plate 9, so that the two screen plates 3 are fitted together and replaced. During this process, the two connecting plates 11 are close to and pressed against the pressing cylinder 12. Under the action of the pressing cylinder 12 in the shape of a truncated cone, the two connecting plates 11 drive the screen plates 3 to move close to the first turntable 4. The connecting plates 11 move on the movable plate 9, so that the two screen plates 3 shake horizontally.

[0044] The pressing cylinder 12 is inclined and arranged in an inclined state. When the first rotating disk 4 rotates with the second rotating disk 5, the connecting plate 11 presses and contacts the pressing cylinder 12 during the process of driving the screen plate 3 to rotate and exchange positions. The position of the pressing cylinder 12 remains unchanged, and the connecting plate 11 rotates along the pressing cylinder 12. The pressing cylinder 12 is inclined, so that the two screen plates 3 move relative to each other during the exchange process, which is convenient for turning over the materials to be dried between the two screen plates 3.

[0045] It is worth noting that: since the pressing cylinder 12 is distributed in an inclined manner, the amplitudes of the two screen plates 3 approaching the first rotating disk 4 vary differently, thereby further increasing the relative shaking effect between the two screen plates 3 .

[0046] The power part includes a motor 14 (which can be changed to rotate clockwise) and a matching part connected and fixed to the baking oven body 2. A rotating groove 15 is opened on the first rotating disk 4. The output shaft of the motor 14 is fixedly connected to a rotating rod 16 that penetrates the rotating groove 15. The rotating rod 16 is rotatably connected to the edge of the second rotating disk 5. The rotating rod 16 acts on the plug-in board 6 through the matching part.

[0047] The motor 14 (the present application can also use manual method to drive the rotating rod 16 to rotate) rotates, so that the second rotating disk 5 rotates at the original position (the contact surface between the first rotating disk 4 and the second rotating disk 5 is a smooth surface, and the second rotating disk 5 will not affect the first rotating disk 4 due to the effect of friction);

[0048] Within a half-turn of the rotating rod 16 that performs circular motion, the plug-in plate 6 is stably plugged into the second rotating disk 5 under the action of the matching piece, so that the first rotating disk 4 rotates synchronously with the second rotating disk 5. At this time, the movable plate 9 does not slide along the second rotating disk 5, so that the two combined and matched screen plates 3 drive the middle part of the drying material to be rotated 180°, so that the lower screen plate 3 and the upper screen plate 3 are exchanged.

[0049] The rotating rod 16 that makes circular motion continues to rotate for another half circle. Under the action of the matching piece, the plug plate 6 is moved away from the second rotating disk 5. The first rotating disk 4 does not rotate with the second rotating disk 5. The first rotating disk 4 keeps the same position. The second rotating disk 5 rotates by itself to drive the movable plate 9 to rotate, so that the two screen plates 3 are moved away from each other.

[0050] In this way, the two screen plates 3 are replaced at intervals, thereby turning over the material to be dried, thereby ensuring comprehensive drying of the material to be dried.

[0051] The matching parts include two wedge-shaped blocks 17 that are pressed against the rotating rod 16. A movable frame 18 connected and fixed to the plug-in board 6 is slidably matched in the first rotating disk 4. The two wedge-shaped blocks 17 are respectively connected and fixed to the movable frame 18 and the plug-in board 6. A toggle rod 23 is fixedly connected to the inner wall of the baking oven body 2. The toggle rod 23 penetrates into the rotating groove 15 of the first rotating disk 4 and is pressed against the wedge-shaped blocks 17. A fixing part for fixing the position of the plug-in board 6 is provided in the first rotating disk 4.

[0052] In the half circle of the rotating rod 16 that makes circular motion, the rotating rod 16 presses against the wedge block 17 located above, so that the movable frame 18 and the plug-in board 6 move upward, the plug-in board 6 plugs into the second rotating disk 5, the first rotating disk 4 rotates with the second rotating disk 5, and under the action of the fixing member, it is ensured that the plug-in board 6 is firmly plugged into the second rotating disk 5, and at this time, the rotating rod 16 passes over the wedge block 17 located above;

[0053] Then, the rotating rod 16 that makes a circular motion continues to rotate for another half circle, and the wave rod 23 presses against the wedge block 17 located below and passes over the wedge block 17 located below, so that the movable frame 18 and the plug-in board 6 move downward, and the plug-in board 6 is away from the second rotating disk 5. The first rotating disk 4 will not rotate with the second rotating disk 5. At this time, the rotating rod 16 does not contact the wedge block 17 (the number of rotating rods 16 and the toggle rod 23 in this application is increased according to the number of circles, so as to facilitate the actual selection of multiple circles or half a circle to turn over the dried material), and under the action of the fixing member, it is ensured that the plug-in board 6 is firmly away from the second rotating disk 5;

[0054] The rotating rod 16 that performs circular motion will not collide with the wave rod 23, and the rotating rod 16 only acts on the wedge block 17 located above, and will not act on the wedge block 17 located below and on the plug board 6;

[0055] The wave rod 23 only presses the wedge block 17 located below and on the plug-in board 6, and does not act on the wedge block 17 located above. The two wedge blocks 17 are staggered in the horizontal direction.

[0056] The fixing member includes an elastic pressing block 19 movably embedded in both sides of the plug board 6, and a T-shaped plate 20 matched with the elastic pressing block 19 is fixedly connected in the first rotating disk 4, and the elastic pressing block 19 is in a trapezoidal shape;

[0057] When the plug-in board 6 is plugged into the second turntable 5, the first turntable 4 rotates synchronously with the second turntable 5, and the elastic pressing block 19 on the plug-in board 6 presses against the upper part of the T-shaped plate 20 to prevent the plug-in board 6 from moving downward, thereby ensuring that the plug-in board 6 is stably plugged into the second turntable 5;

[0058] When the plug board 6 is away from the second turntable 5, the first turntable 4 is stationary (the rotation between the first turntable 4 and the baking oven body 2 is friction rotation), and the elastic pressing block 19 on the plug board 6 presses against the lower part of the T-shaped plate 20 to prevent the plug board 6 from moving upward.

[0059] The movable frame 18 is provided with a limiting groove 21 that slidably cooperates with the movable plate 9. The side of the movable plate 9 slidably cooperates with the inner wall of the movable frame 18 to increase the limiting effect and further ensure the stability of the relative movement between the movable frame 18 and the movable plate 9.

[0060] A cover plate 22 is provided above the baking furnace body 2. The gas pipe on the cover plate 22 corresponds to the material feed port. A control valve is provided on the gas pipe (not shown in the figure, which is a conventional technology). The cover plate 22 is opened to facilitate placing the material to be dried between the two screen plates 3. Then the cover plate 22 is closed. The hot air generated by the combustion of the solid material in the combustion chamber 1 enters the baking furnace body 2, acts on the material to be dried on the screen plate 3, and the excess hot air slowly flows out from the gas pipe.

[0061] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
