Description

Technical Field

[0001] The present invention relates to the technical field of woks, and particularly to a biomass wok. Background Art

[0002] Steaming and frying can, with the action of moisture and temperature, cause great changes in the internal structure of oilseed embryo slices. For example, cells are further damaged, promoting protein aggregation and denaturation, which is conducive to the separation of oil from the embryo slices, and also plays an important role in improving the quality of crude oil. Therefore, the quality of steaming and frying has a direct impact on the smooth progress of the entire oil production process, the oil yield, the quality of the oil, and the quality of the cake.

[0003] However, existing multi-stage steaming and frying equipment is powered by steam. Due to the limited temperature of steam, the material cannot be fully heated. In addition, when the existing multi-stage steaming and frying equipment tumbles the material, it is easy for the material to fall from the upper-stage steaming wok into the lower-stage steaming wok, resulting in uneven humidity of the material on each layer, thus affecting the frying effect of the material. For this reason, a biomass wok is proposed. Summary of the Invention

[0027] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 - 9 , the present invention provides a technical solution: a biomass frying pan, including a base 2, a plurality of stir-frying mechanisms 1 vertically stacked and fixedly installed on the top of the base 2, and a plurality of stir-frying mechanisms 1 share the same heating mechanism 3. The stir-frying mechanism 1 includes a first circular plate 11 and a second circular plate 12. An outer cylinder 113 is sleeved outside the first circular plate 11 and the second circular plate 12. A second heating cavity 19 is formed between the first circular plate 11 and the second circular plate 12. The heating mechanism 3 is used to provide heat to the second heating cavity 19. A stir-frying mechanism 4 is rotatably installed on the top of the second circular plate 12. The stir-frying mechanism 4 includes two spiral feeding plates 42 slidably connected to the top of the second circular plate 12.

[0029] A speed reduction motor 21 is fixedly installed on the top of the base 2. A driving rod 22 is fixedly installed on the output shaft of the speed reduction motor 21. The driving rod 22 rotates through the first circular plate 11 and the second circular plate 12 on multiple frying mechanisms 1. The frying mechanism 4 includes a connecting socket 41 fixedly sleeved on the driving rod 22. One end of each of the two spiral feeding plates 42 close to the center of the circle is fixedly connected to the connecting socket 41, and the two spiral feeding plates 42 are symmetrically distributed about the center. The end of the spiral feeding plate 42 far from the center of the circle is slidably connected to the inner wall of the outer cylinder 113 and forms a feeding port 46 with the other spiral feeding plate 42. Two spiral channels 47 are formed between the two spiral feeding plates 42. A positioning frame 23 is fixedly installed on the inner wall of the inner cylinder 13 in the uppermost frying mechanism 1, and the driving rod 22 rotates through the positioning frame 23.

[0030] The end of the spiral feeding plate 42 far from the center of the circle is slidably connected to the inner wall of the outer cylinder 113. Two feeding plates 45, two spiral baffles 43 and two discharging grooves 44 are fixedly installed between the two spiral feeding plates 42. The two feeding plates 45, the two spiral baffles 43 and the two discharging grooves 44 are symmetrically distributed about the center. One end of each of the two spiral baffles 43 close to the center of the circle is fixedly connected to the connecting socket 41. The two sides of the two discharging grooves 44 are fixedly connected to the corresponding spiral baffles 43 and feeding plates 45 respectively.

[0031] The discharging groove 44 is fixedly embedded in the two spiral feeding plates 42. The feeding plate 45 is inclined, and the bottom end of the feeding plate 45 is slidably connected to the top of the second circular plate 12. A notch 441 is formed on one side of the discharging groove 44 close to the feeding plate 45. The top of the feeding plate 45 is flush with the bottom inner wall of the discharging groove 44 through the notch 441. The bottom inner wall of the discharging groove 44 is inclined, and the side of the bottom of the discharging groove 44 close to the connecting socket 41 is higher than the other side.

[0032] An inner cylinder 13 is fixedly installed on the top of the second circular plate 12. The same annular retaining ring 14 is fixedly installed between the second circular plate 12 and the outer cylinder 113. A first heating cavity 18 is formed between the outer cylinder 113 and the inner cylinder 13. A smoke exhaust duct 15 is fixedly installed through the first heating cavity 18. A smoke exhaust pipe 16 is installed on the smoke exhaust duct 15 and is communicated with it. A plurality of communication ports 121 distributed in a circumferential array are formed on the second circular plate 12. The first heating cavity 18 and the second heating cavity 19 are communicated through the plurality of communication ports 121.

[0033] Furthermore, the smoke exhaust pipes 16 on each frying mechanism 1 are coaxially arranged, and the smoke exhaust pipes 16 are fixedly connected to each other in sequence. The bottom of the lowermost smoke exhaust pipe 16 is sealed.

[0034] A communicating pipe 114 is fixedly installed through the inner cylinder 13, and the communicating pipe 114 communicates with the second heating chamber 19. A same blanking pipe 110 is fixedly installed through between the second circular plate 12 and the first circular plate 11. A fire baffle 118 is fixedly installed between the first circular plate 11 and the second circular plate 12. The fire baffle 118 is on the axis of the communicating pipe 114. A plurality of support rods 112 distributed at equal intervals are also fixedly installed between the first circular plate 11 and the second circular plate 12. A discharge pipe 115 is fixedly installed at the bottom of the first circular plate 11 of the lowest stir-frying mechanism 1, and the discharge pipe 115 communicates with the corresponding blanking pipe 110.

[0035] Further, the fire baffle 118 can block the flames and high-temperature flue gas ejected from the communicating pipe 114. By making the flames and high-temperature flue gas stay at the center of the first heating chamber 18, it prevents the flames and high-temperature flue gas from directly burning the inner wall of the outer cylinder 113.

[0036] Except for the lowest stir-frying mechanism 1, rectangular pipes 116 are fixedly installed through the first circular plates 11 of the other stir-frying mechanisms 1. The rectangular pipes 116 penetrate through the corresponding outer cylinders 113, and a same air outlet pipe 117 is fixedly installed on the plurality of rectangular pipes 116.

[0037] Further, since the uppermost stir-frying mechanism 1 is open, the moisture and dust generated during stir-frying the materials will be directly discharged. The moisture and dust generated during stir-frying the materials by the other stir-frying mechanisms 1 will float up, enter the air outlet pipe 117 through the corresponding rectangular pipes 116 and be discharged to the outside of the device through the air outlet pipe 117. The bottom end of the air outlet pipe 117 is sealed.

[0038] A same hatch 17 is fixedly installed through the outer cylinder 113 and the inner cylinder 13. The hatch 17 is located above the second circular plate 12. An observation window 111 is fixedly installed through the outer cylinder 113. The observation window 111 is located between the first circular plate 11 and the second circular plate 12.

[0039] Further, except that the uppermost stir-frying mechanism 1 is open, the rest of the stacked ones are sealed. Through the hatch 17, materials can be put onto the second circular plate 12 of the sealed stir-frying mechanism 1 or the materials on the second circular plate 12 can be taken out, and the top of the second circular plate 12 can be cleaned. And through the observation window 111, the flame situation in the second heating chamber 19 can be observed.

[0040] The heating mechanism 3 includes a furnace frame 31. A plurality of combustion furnaces 32 arranged longitudinally in a stacked manner are fixedly installed in the furnace frame 31. The combustion furnaces 32 are provided with furnace openings 321. The furnace openings 321 are fixedly connected and communicate with the corresponding communicating pipes 114. The furnace frame 31 is provided with a distributing pipe 33 communicating with the plurality of combustion furnaces 32. A funnel 36 is provided on the distributing pipe 33. A hopper 34 is provided on one side of the furnace frame 31. A hoist 35 is provided between the bottom of the hopper 34 and the top of the funnel 36.

[0041] In this embodiment: during use, biomass pellets are put into the feed hopper 34, and the elevator 35 conveys the biomass pellets in the hopper 34 into the funnel 36 and evenly distributes them into each combustion furnace 32 through the material distribution pipe 33. The biomass pellets burn in the combustion furnace 32, and the flame and high-temperature flue gas generated by the combustion of the biomass pellets enter the second heating chamber 19 through the connecting pipe 114, and then enter the first heating chamber 18 through a plurality of connecting ports 121. The waste gas generated by combustion is then discharged into the exhaust pipe 16 through the exhaust flue 15, and then the waste gas is discharged out of the device through the exhaust pipe 16;

[0042] When stir-frying the material, first put the material into the uppermost stir-frying mechanism 1. When the material falls on the uppermost circular plate two 12, the high temperature in the first heating chamber 18 and the second heating chamber 19 will be transferred to the material on the circular plate two 12 through the circular plate two 12 and the inner cylinder 13;

[0043] By starting the reduction motor 21 to drive the driving rod 22 to rotate, the driving rod 22 drives the entire stir-frying mechanism 4 to rotate. As shown in Figure 7 、 Figure 8 , since the circular plate two 12 is stationary, the material on the circular plate two 12 is in a relatively stationary state. When the stir-frying mechanism 4 rotates clockwise, as the spiral feeding plate 42 rotates clockwise, the material on the circular plate two 12 will enter the spiral channel 47 formed by the two spiral feeding plates 42 through the feeding port 46. And because the spiral feeding plate 42 keeps rotating clockwise, at this time, the spiral feeding plate 42 will apply a centripetal force to the material in the spiral channel 47, causing the material in the spiral channel 47 to continuously gather towards the center of the circular plate two 12;

[0044] When the material in the spiral channel 47 approaches the inclined feeding plate 45, the subsequent material gathering towards the center of the circular plate two 12 will push the front material onto the feeding plate 45. When the material on the feeding plate 45 reaches the blanking groove 44, under the action of gravity, the material will roll towards the feeding port 46 along the inner wall of the bottom of the inclined feeding plate 45;

[0045] Since the end of the blanking groove 44 far from the center is close to the feeding port 46, when the material falls from the blanking groove 44, it will just be shoveled into the feeding port 46 again;

[0046] When the material moves from the feeding port 46 to the feeding plate 45 and then from the blanking groove 44 to the feeding port 46, it can drive the material to be fully stirred. It can not only avoid the situation of material accumulation, but also reduce the material falling into the corresponding blanking pipe 110. During this process, the material can be fully stir-fried;

[0047] As shown in Figure 7 、Figure 8 As shown, after the frying mechanism 4 rotates clockwise for a period of time, then control the frying mechanism 4 to rotate counterclockwise. During this process, the spiral feeding plate 42 continuously moves the material away from the base 2. At this time, the material will be pushed by the spiral feeding plate 42 into the feeding pipe 110, and the material falling into the feeding pipe 110 will drop onto the second circular plate 12 of the frying mechanism 1 located below;

[0048] When the material passes through multiple frying mechanisms 1 from top to bottom, it will be fully fried. The material in the lowermost frying mechanism 1 will fall into the corresponding feeding pipe 110 after frying and will finally be discharged through the outer cylinder 113.

[0049] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
