[0032] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0033] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0034] Reference Figures 1-7 As shown, a grain and oil processing drying device includes: a drying chamber 100 and a dust collection box 102 located below the drying chamber 100 and connected to the drying chamber 100 via a connecting pipe 105. The drying chamber 100 is provided with a feed inlet 101, and a drying mechanism 200 for stirring and drying grain and oil raw materials is provided inside the drying chamber 100. The dust collection box 102 is provided with a dust removal mechanism 300 for removing dust from the dried grain and oil raw materials.

[0035] The drying mechanism 200 includes a heating element and a stirring element that stirs the grain and oil raw materials during heating.

[0036] In operation, the grain and oil raw materials to be dried are fed into the drying chamber 100 through the feed inlet 101. The drying mechanism 200 is then activated, and its heating element begins to heat the raw materials within the drying chamber 100. Simultaneously, the stirring element starts to agitate the raw materials, ensuring uniform heating and improving drying efficiency. The dried raw materials fall into the dust collection box 102 through the connecting pipe 105. The dust collection mechanism 300 is activated to remove dust from the raw materials, eliminating impurities and small particles. The coordinated operation of the heating and stirring elements ensures uniform heating of the grain and oil raw materials within the drying chamber 100, effectively shortening drying time and improving drying efficiency. The dust collection mechanism 300 removes impurities and small particles from the dried raw materials, further enhancing the purity and quality of the product.

[0037] Reference Figures 4-5 As shown, the heating element includes: a heating tube 202, a turntable 203, and a heating stirring rod 205; wherein,

[0038] The drying oven 100 has a turntable 203 rotatably mounted on its top. A heating tube 202 is coaxially mounted on the turntable 203 and a plurality of rotating shafts 204 arranged parallel to the heating tubes 202 are rotatably mounted via bearings 207. A plurality of heating and stirring rods 205 are fixedly mounted at intervals on the circumferential surface of the rotating shafts 204. The heating and stirring rods 205 have a plurality of air outlets 206 for further heating of the grain and oil raw materials.

[0039] In the above scheme, when it is necessary to dry grain and oil raw materials, the heating tube 202 is first activated. The heating tube 202 starts to generate heat, and the air outlet 206 on the heating stirring rod 205 releases the hot air generated by the heating tube 202 to further heat and dry the grain and oil raw materials. The combined action of the heating tube 202 and the heating stirring rod 205 can ensure that the grain and oil raw materials are heated evenly and fully during the drying process, thereby improving the drying efficiency.

[0040] Reference Figures 4-5 As shown, the stirring component includes: a rotary motor 201, a driving gear 208, and a driven gear 209; wherein,

[0041] The drying oven 100 is fixedly equipped with a rotary motor 201 whose output shaft is coaxial with the turntable 203 and whose top end is fixedly connected to the turntable 203. The heating tube 202 is fixedly fitted with a drive gear 208, and multiple sets of rotating shafts 204 are fixedly fitted with driven gears 209 that mesh with the drive gear 208.

[0042] When it is necessary to stir the grain and oil raw materials, the rotary motor 201 is started. The output shaft of the rotary motor 201 drives the turntable 203 to rotate. The turntable 203 is coaxially set with the heating tube 202, so the heating tube 202 also rotates. The rotation of the turntable 203 drives multiple sets of rotating shafts 204 to rotate through the meshing of the driving gear 208 and the driven gear 209. The heating and stirring rods 205 on the rotating shafts 204 rotate with the rotation of the rotating shafts 204, stirring the grain and oil raw materials in the drying box 100.

[0043] Reference Figures 4-6 As shown, the dust removal mechanism 300 includes: a rotating shaft 302, a spiral blade 304, and a dust collection box 305; wherein,

[0044] The dust collection box 102 is equipped with multiple sets of rotating shafts 302 that rotate in parallel with each other. Each set of rotating shafts 302 is fixedly equipped with a spiral blade 304. The dust collection box 102 is equipped with a drive motor 301 whose output shaft is parallel to the shaft and whose top end is fixedly connected to one of the sets of rotating shafts 302. Every two sets of rotating shafts 302 are connected by a first transmission belt 303. The side wall of the dust collection box 102 is fixedly equipped with a dust collection box 305 for dust collection that communicates with the dust collection box 102.

[0045] When the dust removal process in the grain and oil processing drying equipment needs to be started, the drive motor 301 is started first. The output shaft of the drive motor 301 drives one set of rotating shafts 302 to rotate. Since every two sets of rotating shafts 302 are connected by the first transmission belt 303, all rotating shafts 302 will rotate synchronously. The spiral blades 304 on the rotating shafts 302 rotate with the rotation of the rotating shafts 302, separating the fine impurities in the grain and oil raw materials from the raw materials. The dust collection device in the dust collection box 305 is started, sucking the dust and impurities into the dust collection box 305 to complete the dust removal operation.

[0046] Reference Figure 4 As shown, the dust collection box 102 is equipped with a screening mechanism 400 located above the dust collection mechanism 300 for screening large particles of impurities such as sand and gravel.

[0047] In the above scheme, during the grain and oil processing and drying process, the raw materials containing large particles such as sand and gravel first enter the dust removal box 102. The screening mechanism 400 is located above the dust removal mechanism 300. After the raw materials enter the dust removal box 102, the screening mechanism 400 begins to screen the raw materials and screen out the large particles such as sand and gravel.

[0048] Reference Figures 6-7 As shown, the screening mechanism 400 includes a filter element and a vibrating element. The filter element includes a filter plate 403, a spring column 405, and a placement plate 406.

[0049] The dust collection box 102 has an installation groove 404 on its inner sidewalls that are far apart from each other, located above the rotating shaft 302. Multiple sets of spring columns 405 are fixedly arranged at intervals in the installation groove 404. A placement plate 406 is fixedly arranged at the top of the spring column 405. A filter plate 403 for screening and filtering is slidably arranged in the dust collection box 102 and placed above the placement plate 406.

[0050] In the above scheme, the raw material containing large particles of impurities such as sand and gravel enters from the inlet of the dust collection box 102 and falls onto the filter plate 403. The raw material is screened on the filter plate 403. Small particles of grain or material fall through the mesh of the filter plate 403 into the dust collection mechanism 300 below for further processing, while large particles of impurities such as sand and gravel are left on the filter plate 403. During screening, the vibrating component causes the filter plate 403 to vibrate, which helps to accelerate the screening process and prevent clogging.

[0051] Reference Figures 6-7 As shown, the vibrating component includes a drive shaft 401 and a cam 407; the drive shaft 401 is rotatably disposed above the filter plate 403 inside the dust collection box 102, and multiple sets of cams 407 with edges in contact with the filter plate 403 are fixedly disposed on the drive shaft 401 at intervals, and the drive shaft 401 is connected to the rotating shaft 302 through the second transmission belt 402.

[0052] When the screening process needs to be started, the drive shaft 401 of the vibrating element also begins to rotate. Since the drive shaft 401 is connected to the rotating shaft 302 via the second transmission belt 402, the vibrating element will also start synchronously when the dust removal mechanism 300 starts working. The cam 407 on the drive shaft 401 rotates with the rotation of the drive shaft 401, and its edge contacts and pushes the filter plate 403, causing the filter plate 403 to vibrate. The vibration accelerates the screening process of the raw materials on the filter plate 403, and small grain particles or materials are more likely to fall into the dust removal mechanism 300 below through the mesh, which helps to prevent clogging in the screening process and ensures the continuity and efficiency of the screening process.

[0053] Reference Figures 1-4 As shown, a sealing door 104 is rotatably provided on the surface of the dust collector 102 at a position corresponding to the filter plate 403, and a discharge pipe 103 is provided on the bottom surface of the dust collector 102.

[0054] In the above scheme, when it is necessary to clean or replace the filter plate 403, the operator can open the sealed door 104 to easily access the inside of the dust collection box 102. The pure raw material after screening and dust removal is discharged from the dust collection box 102 through the discharge pipe 103 and enters the subsequent processing or storage stage.

[0055] In summary, the grain and oil processing drying equipment provided by this utility model allows grain and oil raw materials to enter the drying chamber 100 through the feed inlet 101. The rotary motor 201 is started, and the output shaft of the rotary motor 201 drives the turntable 203 to rotate, thereby causing the heating tube 202 to rotate.

[0056] Since a driving gear 208 is fixedly sleeved on the heating tube 202, and driven gears 209 meshing with the driving gear 208 are fixedly sleeved on multiple sets of rotating shafts 204, the rotation of the driving gear 208 drives the driven gears 209 to rotate, thereby causing the multiple sets of rotating shafts 204 to rotate. When the rotating shafts 204 rotate, multiple sets of heating and stirring rods 205 fixed at intervals on their circumferential surfaces rotate accordingly, stirring the grain and oil raw materials. At the same time, the heating tube 202 and the heating and stirring rods 205 generate heat, and the air vents 206 on the heating and stirring rods 205 can further heat the grain and oil raw materials, achieving the stirring and drying of the grain and oil raw materials. The dried grain and oil raw materials enter the dust collection box 102 through the connecting pipe 105. The dried grain and oil raw materials first fall onto the filter plate 403. Since the drive shaft 401 inside the dust collection box 102 is connected to the rotating shaft 302 via the second transmission belt 402, after the drive motor 301 is started, the rotating shaft 302 rotates, driving the drive shaft 401 to rotate. When the drive shaft 401 rotates, multiple sets of fixed cams 407 on it rotate. The edges of the cams 407 contact the filter plate 403, causing the filter plate 403 to vibrate on the placement plate 406, thereby screening the grain and oil raw materials falling onto the filter plate 403. Large particles such as stones are retained on the filter plate 403 and can be cleaned by opening the sealing door 104 on the surface of the dust collection box 102 corresponding to the filter plate 403. After screening, the grain and oil raw materials continue to fall to the dust collection mechanism 300. The drive motor 301 is started, and the output shaft of the drive motor 301 drives one set of rotating shafts 302 to rotate. Since every two sets of rotating shafts 302 are connected by the first transmission belt 303, multiple sets of rotating shafts 302 rotate. When the rotating shafts 302 rotate, the spiral blades 304 fixed on them rotate, pushing the grain and oil raw materials to move inside the dust collection box 102. At the same time, the dust collection box 305 sucks up the dust in the dust collection box 102, removing dust and other impurities from the grain and oil raw materials, thus achieving dust removal. The grain and oil raw materials after dust removal are discharged through the discharge pipe 103 at the bottom of the dust collection box 102.

However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0058] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0059] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
