Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and more particularly to a roller scraper dryer with an adjustable scraper. Background Art

[0002] The drum scraper dryer is an internal heating conduction type rotary continuous drying equipment. It heats the drum surface through water vapor or other heat carriers, so that the liquid or slurry material forms a thin film on the drum surface, and is dried during the drum rotation. The dried material is scraped off the drum surface by a scraper, exposing a new drum surface to contact the raw material again, forming a new film for drying. This continuous drying method greatly improves the drying efficiency. However, in the existing drum scraper dryer, when the drum contacts the raw material, the raw material adhered to the drum may be uneven, and the slurry cannot be scraped into a material layer with completely uniform thickness, resulting in uneven thickness of the material layer formed after the slurry is dried on the drum. Under the same drying time, the drying effect of the uneven thickness of the material layer is different, which affects the drying effect. In addition, the scraper position of the current drum scraper dryer is fixed and cannot be adjusted according to the required material layer thickness, which affects the distribution of the raw material on the drum. The position of the scraper is fixed, and the position between the scraper and the drum cannot be adjusted, making it difficult to control the drying degree and scraping effect of the material. Therefore, it is necessary to provide a drum scraper dryer with an adjustable scraper to solve the problems raised in the above background technology. Summary of the invention

[0003] To achieve the above object, the present invention provides the following technical solution: a drum scraper dryer with adjustable scraper, comprising: A frame body, carrying the scraper drum dryer, and a driving mechanism is arranged inside the frame body, wherein the bottom of the driving mechanism is in the same horizontal plane as the bottom of the frame body; The material trough is fixed on the frame and located above the driving mechanism; A roller is rotatably arranged on the frame, and the bottom of the roller is located in the material trough; The rotating assembly is fixed on the frame and fixedly connected to one end of the drum; The rotating ring assembly comprises a first rotating ring assembly and a second rotating ring assembly which are symmetrically arranged and are respectively rotatably arranged on the frames at both ends of the drum and connected to the driving mechanism, and the first rotating ring assembly and the rotating assembly are located at the same end of the drum; The trowel scraper device is fixed on the frame and located on the side of the drum; The scraper device has two ends respectively fixed on the rotating ring components at the two ends of the drum and is located on the side of the drum away from the leveling scraper device.

[0004] Furthermore, preferably, the drum is provided with a steam inlet pipe at one end of the rotating assembly and a siphon tube at the other end, and the steam inlet pipe passes through the center of the first rotating ring assembly to connect the interior of the drum and the steam generator; the siphon tube passes through the center of the second rotating ring assembly to penetrate into the interior of the drum.

[0005] That is to say, under the action of the steam generator, steam is transported to the inside of the drum through the steam inlet pipe, the inside of the drum is heated to a certain temperature, and at the same time, the siphon tube discharges the condensed water inside the drum in time through the other end of the drum. At this time, the rotating assembly drives the drum to rotate, and when the drum passes through the material trough, the raw materials adhere to the drum, and the raw materials are smoothed and scraped to form a uniformly distributed material layer on the drum. The material layer is dried during the rotation of the drum, and the dried material layer is scraped off by the scraper device and collected.

[0006] Further, as a preference, the rotating ring assembly comprises: The rotating ring bodies are symmetrically arranged with two of them, rotatably arranged on the frame body, and connected with the driving mechanism; Two fixed annular surfaces are symmetrically arranged and fixed to the outsides of the two rotating ring bodies respectively, and the fixed annular surfaces between the first rotating ring assembly and the second rotating ring assembly are respectively fixedly connected to the two ends of the scraping device; The arc surface is provided with a plurality of blocks in an annular distribution and fixed between the rotating ring bodies on both sides.

[0007] That is to say, driven by the driving mechanism, the rotating ring assemblies at both ends of the drum are driven to rotate through the rotating ring body, and then the scraper device is driven to rotate around the central axis of the drum through the fixed ring surface, and the position and angle between the scraper device and the drum are adjusted to control the dryness of the material and the scraping effect.

[0008] Further, as a preference, the smoothing scraper device comprises: A fixed platform is fixed on the frame and is located on the side of the drum; Two fixed plates are symmetrically arranged and vertically fixed at both ends of the fixed platform, and the fixed plates are parallel to the end surface of the drum; A first rotating shaft is arranged above the fixed platform and is rotatably connected to the fixed plate; A first motor is fixed to the outer side of one side fixing plate, and the first motor is fixedly connected to the first rotating shaft; The scraper assembly is arranged between the fixing plates at both sides and fixed on the first rotating shaft; Two adjusting panels are symmetrically arranged and fixed on a side of the fixing plate close to the drum, and an adjusting slideway is arranged on the adjusting panel; The distribution component has two ends arranged in the adjustment slideways on the adjustment panel and is arranged between the scraper component and the roller.

[0009] That is to say, when the rotating component drives the drum to rotate, after the drum passes through the material trough to adhere to the raw materials, the drum with the raw materials adhered to it passes through the distribution component to remove some excess raw materials on the drum surface and evenly distribute the raw materials on the drum. Then, when passing through the scraper component, the original surface of the drum is scraped flat, so that the raw materials are evenly dried, which helps to improve the drying effect of the raw materials.

[0010] As a preferred embodiment, after determining the required thickness of the raw material on the roller, the spacing between the distribution component and the roller is adjusted by adjusting the panel so that the spacing between the distribution component and the roller is greater than the required thickness, that is, while scraping off excess raw material, sufficient raw material is ensured to be evenly covered on the roller, and then the first motor drives the first rotating shaft to rotate, and the spacing between the scraper component and the roller is adjusted so that the spacing between the scraper component and the roller is the same as the required raw material thickness, and then during the rotation of the roller, while scraping off excess raw material in the distribution component, the remaining raw material is evenly dispersed on the roller, and then in the scraper component, scrape off excess raw material, so that the evenly distributed raw material is dried on the roller and scraped off when passing through the scraper device. When the scraper component scrapes off excess raw material, the excess raw material can flow to the distribution component, providing a certain amount of raw material supplement for the distribution component to evenly distribute the raw material on the roller.

[0011] Further, as a preference, the scraper assembly comprises: A scraper is fixed on the first rotating shaft, and a notch connected to the distribution component is provided on the inclined surface of the scraper opposite to the roller; The sliding baffle is slidably arranged inside the inclined surface of the scraper, and the bottom thereof is in contact with the top of the distribution component. That is, when the first motor drives the first rotating shaft to rotate in a direction away from the roller, the scraper is driven away from the roller, so that the distance between the scraper and the roller becomes larger, that is, the thickness of the raw material on the roller becomes thicker, and at the same time, under the action of the distribution component, the sliding baffle moves up; conversely, when the first motor drives the first rotating shaft to rotate in a direction close to the roller, the scraper is driven close to the roller, so that the distance between the scraper and the roller becomes smaller, that is, the thickness of the raw material on the roller becomes thinner, and at the same time, under the action of the distribution component, the sliding baffle moves down.

[0012] Further, preferably, the distribution component comprises: The distribution platform is obliquely arranged between the two side adjustment panels and connected to the scraper through the notch on the inclined surface of the scraper; The shaft sections are symmetrically arranged with two of them, fixed at both ends of the distribution platform, and slidably connected with the adjustment slideways on the adjustment panel; A plurality of distribution plates are linearly distributed and vertically arranged on the plane of the distribution platform, and are slidably connected to the distribution platform, and the top of the distribution plate is in contact with the bottom of the sliding baffle; The pushing mechanisms are symmetrically distributed with two of them, which are slidably arranged at the two ends of the distribution platform, and the pushing mechanisms are provided with pushing shafts.

[0013] That is to say, under the action of the distribution platform, excess raw materials on the drum can be scraped off, and under the action of the shaft section, the distribution platform is driven to move on the adjustment slide through the adjustment panel, and then the distance between the distribution platform and the drum is adjusted. Then, under the action of the pushing mechanism, the distribution plate is driven to move back and forth on the distribution platform through the pushing shaft to disperse the raw materials on the drum, so that the raw materials are evenly distributed on the drum, and then trimmed by the scraper, which effectively improves the drying effect of the raw materials.

[0014] Further, preferably, the pushing mechanism is always in the scraper, and the pushing mechanism slides on the distribution platform along the direction in which the distribution plate is set, and one end of the distribution plate close to the roller is an inclined surface.

[0015] That is to say, before the roller with the raw material adhered to it passes through the dispersion platform, the distribution plate can be driven by the pushing mechanism to slide on the distribution platform toward the position of the roller, and the distance between the distribution plate and the roller can be adjusted so that the distance between the inclined surface of the distribution plate and the roller is smaller than the distance between the distribution platform and the roller, and larger than the required raw material thickness. Then, driven by the pushing shaft of the pushing mechanism, the distribution plate moves back and forth on the distribution platform, so that the raw material can be better dispersed on the roller.

[0016] Further, as a preference, the scraping device comprises: A fixed shaft, with two ends respectively fixed to the first rotating ring assembly and the second rotating ring assembly; A second rotating shaft, rotatably disposed on the fixed shaft; A scraper plate is fixed on the second rotating shaft; The scraper is fixed on the side of the scraper plate close to the drum; A collecting trough is arranged on the upper part of the scraper plate; Two protective panels are symmetrically arranged, fixed on the second rotating shaft and located on both sides of the scraper plate; The transmission assembly connects the first rotating ring assembly and the second rotating shaft.

[0017] That is to say, under the action of the first rotating ring assembly and the second rotating ring assembly, the scraper device is driven to rotate around the drum through the fixed shaft, and different scraping positions are selected according to the required degree of drying of the material. The longer the raw material is dried on the drum, the better the drying effect. After determining the scraping position, the second rotating shaft can be driven to rotate through the transmission assembly, and then the scraper plate and the scraper can be driven to rotate, and the distance between the scraper and the drum can be adjusted so that the scraper can completely scrape off the dried raw material, and the scraped raw material falls into the collecting trough for collection, and under the action of the protective panel, the raw material can be effectively prevented from splashing to the outside during the scraping process.

[0018] Further, as a preference, the transmission assembly comprises: A rotating gear is fixed on the second rotating shaft and is located outside the protective panel; A transmission gear meshes with the rotating gear; The second motor is fixed on the inner wall of the arc surface in the first rotating ring assembly, and the shaft of the second motor is fixedly connected to the transmission gear.

[0019] That is to say, when the scraper device is adjusted as a whole through the first rotating ring assembly and the second rotating ring assembly, the transmission assembly rotates with the first rotating ring assembly. After the position of the scraper device is determined, the transmission gear is driven to rotate by the second motor, and then the second rotating shaft is driven to rotate by the rotating gear to adjust the position of the scraper so that the scraper can completely scrape off the dried raw materials.

[0020] Compared with the prior art, the present invention has the following beneficial effects: The present invention drives the scraper device to rotate around the axis of the drum by setting a rotating ring assembly, adjusts the position of the scraper device on the drum, adjusts the heating time of the raw material on the drum, that is, adjusts the degree of drying, and simultaneously sets a transmission assembly to adjust the position between the scraper and the drum, thereby improving the scraping effect of the scraper on the material; by setting a smoothing scraper device, the raw material adhered to the drum is smoothed, and the raw material is dispersed by a distribution plate, so that the raw material forms a uniformly distributed material layer on the drum, which helps to improve the drying effect of the raw material.

[0026] That is to say, driven by the driving mechanism 11, the rotating ring assembly 5 at both ends of the roller 3 is driven to rotate through the rotating ring body 511, and then the scraper device 7 is driven to rotate around the central axis of the roller 3 through the fixed ring surface 512, so as to adjust the position and angle between the scraper device 7 and the roller 3 and control the drying degree and scraping effect of the material.

[0027] In this embodiment, the smoothing scraper device 6 includes: A fixed platform 61 is fixed on the frame 1 and is located on the side of the drum 3; Two fixing plates 62 are symmetrically arranged and vertically fixed at both ends of the fixing platform 61, and the fixing plates 62 are parallel to the end surface of the drum 3; A first rotating shaft 63 is disposed above the fixed platform 61 and is rotatably connected to the fixed plate 62; A first motor 64 is fixed to the outer side of the fixed plate 62 at one side, and the first motor 64 is fixedly connected to the first rotating shaft 63; The scraper assembly 65 is disposed between the two side fixing plates 62 and fixed on the first rotating shaft 63; Two adjusting panels 66 are symmetrically arranged and fixed on a side of the fixing plate 62 close to the drum 3, and an adjusting slide is arranged on the adjusting panel 66; The distribution assembly 67 has two ends arranged in the adjustment slideways on the adjustment panel 66 and is arranged between the scraper assembly 65 and the roller 3 .

[0028] That is to say, when the rotating component 4 drives the roller 3 to rotate, after the roller 3 passes through the material trough 2 to adhere to the raw materials, the roller 3 with the raw materials adhered passes through the distribution component 67, removes part of the excess raw materials on the surface of the roller 3, and evenly distributes the raw materials on the roller 3, and then when passing through the scraper component 65, the original surface of the roller 3 is scraped flat, so that the raw materials are evenly dried, which helps to improve the drying effect of the raw materials.

[0029] As a preferred embodiment, after determining the required thickness of the raw material on the roller 3, the spacing between the distribution component 67 and the roller 3 is adjusted by adjusting the panel 66 so that the spacing between the distribution component 67 and the roller 3 is greater than the required thickness, that is, while scraping off excess raw material, sufficient raw material is ensured to be evenly covered on the roller 3, and then the first motor 64 drives the first rotating shaft 63 to rotate, and the spacing between the scraper component 65 and the roller 3 is adjusted so that the spacing between the scraper component 65 and the roller 3 is the same as the required raw material thickness, and then during the rotation of the roller 3, while scraping off excess raw material in the distribution component 67, the remaining raw material is evenly dispersed on the roller 3, and then in the scraper component 65, scrape off excess raw material, so that the evenly distributed raw material is dried on the roller 3 and scraped off when passing through the scraper device 7, and when the scraper component 65 scrapes off excess raw material, the excess raw material can flow to the distribution component 67, providing a certain amount of raw material supplement for the distribution component 67 to evenly distribute the raw material on the roller 3.

[0030] In this embodiment, the scraper assembly 65 includes: The scraper 651 is fixed on the first rotating shaft 63, and a notch connected to the distribution component 67 is provided on the inclined surface of the scraper 651 opposite to the roller 3; The sliding baffle 652 is slidably arranged inside the inclined surface of the scraper 651, and the bottom thereof is in contact with the top of the distribution component 67. That is, when the first motor 64 drives the first rotating shaft 63 to rotate in the direction away from the roller 3, the scraper 651 is driven to move away from the roller 3, so that the distance between the scraper 651 and the roller 3 becomes larger, that is, the thickness of the raw material on the roller 3 becomes thicker, and at the same time, under the action of the distribution component 67, the sliding baffle 652 moves upward; conversely, when the first motor 64 drives the first rotating shaft 63 to rotate in the direction close to the roller 3, the scraper 651 is driven to move close to the roller 3, so that the distance between the scraper 651 and the roller 3 becomes smaller, that is, the thickness of the raw material on the roller 3 becomes thinner, and at the same time, under the action of the distribution component 67, the sliding baffle 652 moves downward.

[0031] In this embodiment, the distribution component 67 includes: The distribution platform 671 is obliquely disposed between the two side adjustment panels 66 and connected to the scraper 651 through the notch on the inclined surface of the scraper 651; Two shaft segments 672 are symmetrically arranged and fixed at both ends of the distribution platform 671 and slidably connected to the adjustment slideways on the adjustment panel 66; A plurality of distribution plates 673 are linearly distributed and vertically arranged on the plane of the distribution platform 671, and are slidably connected to the distribution platform 671, and the top of the distribution plate 673 is in contact with the bottom of the sliding baffle 652; The pushing mechanisms 674 are symmetrically distributed with two of them, which are slidably arranged at the two ends of the distribution platform 671 , and the pushing mechanisms 674 are provided with pushing shafts, and the tops of the two adjacent distribution plates 673 are fixedly connected to the pushing shafts of different pushing mechanisms 674 .

[0032] That is to say, under the action of the distribution platform 671, excess raw materials on the roller 3 can be scraped off, and under the action of the shaft section 672, the distribution platform 671 is driven to move on the adjustment slide through the adjustment panel 66, and then the distance between the distribution platform 671 and the roller 3 is adjusted, and then under the action of the pushing mechanism 674, the distribution plate 673 is driven to move back and forth on the distribution platform 671 through the pushing shaft to disperse the raw materials on the roller 3, so that the raw materials are evenly distributed on the roller 3, and then trimmed by the scraper 651, thereby effectively improving the drying effect of the raw materials.

[0033] In this embodiment, the pushing mechanism 674 is always in the scraper 651, and the pushing mechanism 674 slides on the distribution platform 671 along the direction in which the distribution plate 673 is set, and the end of the distribution plate 673 close to the roller 3 is an inclined surface.

[0034] That is to say, before the roller 3 with the raw material adhered to it passes through the dispersion platform, the distribution plate 673 can be driven by the pushing mechanism 674 to slide toward the position of the roller 3 on the distribution platform 671, and the distance between the distribution plate 673 and the roller 3 can be adjusted so that the distance between the inclined surface of the distribution plate 673 and the roller 3 is smaller than the distance between the distribution platform 671 and the roller 3, and greater than the required raw material thickness. Then, driven by the pushing shaft of the pushing mechanism 674, the distribution plate 673 moves back and forth on the distribution platform 671, so that the raw material can be better dispersed on the roller 3.

[0036] That is to say, under the action of the first rotating ring assembly 51 and the second rotating ring assembly 52, the scraper device 7 is driven to rotate around the drum 3 through the fixed shaft 71. Different scraping positions are selected according to the required degree of drying of the material. The longer the raw material is dried on the drum 3, the better the drying effect. After determining the scraping position, the second rotating shaft 72 can be driven to rotate through the transmission assembly 77, and then the scraper plate 73 and the scraper 74 can be driven to rotate. The distance between the scraper 74 and the drum 3 is adjusted so that the scraper 74 can completely scrape off the dried raw material, and the scraped raw material falls into the collecting trough 75 for collection.

[0038] That is to say, when the scraper device 7 is adjusted as a whole through the first rotating ring assembly 51 and the second rotating ring assembly 52, the transmission assembly 77 rotates along with the first rotating ring assembly 51. After the position of the scraper device 7 is determined, the transmission gear 772 is driven to rotate by the second motor 773, and then the second rotating shaft 72 is driven to rotate by the rotating gear 771, so as to adjust the position of the scraper 74 so that the scraper 74 can completely scrape off the dried raw materials.

[0039] During the specific implementation, firstly, the thickness of the raw material that can be completely dried on the roller 3 is determined according to the raw material, then, the distribution platform 671 is driven to move on the adjustment slide through the adjustment panel 66, and the distance between the distribution platform 671 and the roller 3 is adjusted, so that the distance between the distribution platform 671 and the roller 3 is greater than the required thickness, and the excess raw material can be scraped off, and part of the excess raw material is retained, then the distribution plate 673 is driven to slide toward the position of the roller 3 on the distribution platform 671 through the pushing mechanism 674, and the distance between the distribution plate 673 and the roller 3 is adjusted, so that the distance between the inclined surface of the distribution plate 673 and the roller 3 is less than the distance between the distribution platform 671 and the roller 3, and greater than the required raw material thickness, then the first rotating shaft 63 is driven to rotate through the first motor 64, and the distance between the scraper assembly 65 and the roller 3 is adjusted, so that the distance between the scraper 651 and the roller 3 is the same as the required raw material thickness, and then during the rotation of the roller 3, the distribution platform 671 scrapes off part of the excess raw material on the roller 3, and then the pushing mechanism 674 The delivery shaft drives the distribution plate 673 to move back and forth on the distribution platform 671 to disperse the raw materials on the roller 3 so that the raw materials are evenly distributed on the roller 3. The scraper 651 then trims the raw materials so that the raw materials are evenly distributed on the roller 3 with a standard thickness. The excess raw materials scraped off by the scraper 651 can flow to the distribution component 67 to provide a certain amount of raw material supplement for the distribution component 67 to evenly distribute the raw materials on the roller 3. The roller 3 continues to rotate under the action of the rotating component 4. When passing through the scraping device 7, the scraper 74 completely scrapes the dried raw materials. After scraping, the scraped raw materials fall into the collecting trough 75 for collection, and the fixed shaft 71 can be driven to rotate by the first rotating ring assembly 51 and the second rotating ring assembly 52, thereby driving the scraper device 7 to rotate around the drum 3. Different scraping positions are selected according to the required degree of dryness of the material. After the scraping position is determined, the second rotating shaft 72 is driven to rotate by the transmission assembly 77, thereby driving the scraper plate 73 and the scraper 74 to rotate, and adjusting the distance between the scraper 74 and the drum 3 so that the scraper 74 can completely scrape the dried raw materials.
