Description

Technical Field

[0001] The invention belongs to the technical field of drying, and in particular relates to a drum scraper dryer and a working method thereof. Background Art

[0002] With the gradual improvement of environmental protection requirements, especially in the mixed salt wastewater industry, after industry upgrades, the waste liquids treated today generally show component diversity, high corrosiveness, high COD, supersaturation, etc. Especially for liquids with special properties, the traditional drum scraper dryer feeding method can no longer meet actual use needs.

[0003] Therefore, side spray feeding has become the trend of feeding method for equipment in the mixed salt industry. During the drying process, the side spray device sprays the liquid material onto the outer wall of the drum dryer, and the drum dryer rotates to dry the liquid material; when the dried material abuts against the scraper on one side of the drum dryer, the scraper scrapes the material off the outer wall of the drum dryer.

[0004] However, for liquid materials with special properties, after drying, hard bumps will form on the outer wall of the drum dryer. At this time, if the adjusting scraper directly contacts the bumps, the scraper's cutting edge will be damaged, causing the cutting edge to be broken, thereby affecting the scraper's effect of scraping the material on the outer wall of the drum dryer.

[0005] In the related art, a scraper is typically mounted on a support plate for sliding movement. The scraper is squeezed by the bumps on the drum dryer's outer wall and then slides away from the drum dryer to prevent the scraper's cutting edge from being damaged by hard materials. However, as the scraper slides relative to the support plate, its stability deteriorates. Furthermore, after repeated sliding and resetting, the distance between the scraper and the drum dryer's outer wall increases compared to the preset distance. As the scraper slides relative to the support plate, its fixing bolts become loose, causing the scraper to tilt. This increased distance prevents the scraper from completely removing material from the drum dryer's outer wall.

[0006] Therefore, how to avoid the scraper from being unable to clean the outer wall of the drum dryer due to the increase in the distance between the scraper and the outer wall of the drum dryer is a technical problem that urgently needs to be solved in this field.

[0007] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0070] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0071] In this document, when it is mentioned that a first component is located on a second component, this may mean that the first component may be directly formed on the second component, or that a third component may be interposed between the first component and the second component. In addition, in the drawings, the thickness of components may be exaggerated or reduced in order to effectively describe technical content.

[0072] Herein, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as "at least one of..." when following a list of elements modify the entire list of elements, rather than modifying individual elements in the list. For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0073] The terms used herein are only used to describe specific exemplary configurations and are not intended to be limiting. As used herein, the singular articles "a", "an" and "the" may also be intended to include plural forms, unless otherwise clearly indicated herein. The terms "comprise", "include" and "have" are inclusive and therefore specify the presence of features, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components and / or combinations thereof. The method steps, processes and operations described herein should not be interpreted as necessarily requiring them to be performed in the particular order discussed or shown, unless specifically identified as an execution order. Additional or alternative steps may be adopted.

[0074] As used herein, the phrases "in one embodiment," "according to one embodiment," "in some embodiments," and the like generally refer to the fact that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure. Thus, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," and the like are used to "serve as an example, instance, or illustration." Any implementation, aspect, or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations, aspects, or designs. Instead, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0075] Research has found that the shortcomings of the existing technology are: for liquid materials with special properties, after being dried, hard bumps will be formed on the outer wall of the drum dryer. At this time, the scraper blade will be adjusted to directly contact the bumps, which will damage the blade edge and cause the blade edge to collapse, thereby affecting the scraper's effect of scraping the material on the outer wall of the drum dryer.

[0076] In the related art, a scraper is often slidably mounted on a support plate. After being squeezed by the bumps on the outer wall of the drum dryer, the scraper slides away from the drum dryer to prevent the scraper's cutting edge from being damaged by hard materials. However, as the scraper slides relative to the support plate, its stability deteriorates. Furthermore, after repeated sliding and resetting, the distance between the scraper and the outer wall of the drum dryer increases compared to the preset distance. As the scraper slides relative to the support plate, its fixing bolts become loose, causing the scraper to tilt. This increased distance prevents the scraper from completely removing material from the outer wall of the drum dryer.

[0077] Therefore, how to prevent the scraper from losing stability when sliding, which results in an increase in the distance between the scraper and the outer wall of the drum dryer, is a technical problem that urgently needs to be solved in this field.

[0078] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0079] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0080] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0081] like Figures 1 to 8 As shown, some embodiments provide a roller scraper 4 dryer, comprising: a roller body 1; the roller body 1 is rotatably arranged on a base, a drive motor is provided on one side of the base, and the roller body 1 is transmission-connected to the drive motor. Preferably, the interior of the roller body 1 is hollow, and an air intake pipe is provided on the side of the roller body 1 close to the drive motor, and the air intake pipe is suitable for conveying high-temperature steam into the roller body 1. Furthermore, a heating coil can also be provided in the roller body 1 to facilitate heating the roller body 1. A side loading device 2 is provided on one side of the roller body 1; a plurality of spray holes are provided on the side of the side loading device 2 close to the roller body 1, and the side loading device is suitable for spraying the mixed liquid to the side wall of the roller body 1. After the liquid adheres to the roller body 1, the roller body 1 rotates to achieve the effect of drying the liquid. The support plate 3 is arranged below the side loading device 2 and is inclined; the scraper 4 is parallel to the outer wall of the drum body 1; and a plurality of adjustment assemblies 5 are arranged on the scraper 4 at equal intervals and are suitable for connecting the support plate 3 and the scraper 4. When the drum body 1 rotates until the dried material contacts the scraper 4, the scraper 4 scrapes the material from the outer wall of the drum body 1. When the scraper 4 is pushed toward the side loading device 2 by the material protruding from the outer wall of the drum body 1, the adjustment assembly 5 rotates relative to the scraper 4, and the adjustment assembly 5 cooperates with the support plate 3 to press the scraper 4. Through the cooperation of the adjustment assembly 5, the scraper 4, and the support plate 3, when the scraper 4 slides toward the support plate 3, the adjustment assembly 5 cooperates with the support plate 3 to clamp the scraper 4, preventing the scraper 4 from loosening relative to the support plate 3 during the sliding process, thereby improving the stability of the scraper 4 and preventing the increase in the gap between the scraper 4 and the drum body 1. When the scraper 4 slides toward the drum body 1 , the adjustment assembly 5 does not rotate, but only rotates synchronously with the scraper 4 , thereby preventing the scraper 4 from becoming loose when sliding back.

[0082] When the side loading device 2 transports the liquid to the side wall of the drum body 1, some of the material that is not adsorbed on the surface of the drum body 1 will fall into the bottom trough and be discharged through the discharge port of the trough. Due to the influence of the trough structure, the time required for the liquid to fall into the trough and be discharged from the discharge port is relatively long, and it is always accompanied by the heat radiation of the drum body 1, which causes the supersaturated liquid to evaporate and crystallize again in the trough, precipitating a large amount of crystalline salt, causing the accumulation and blockage of solid salt in the trough and the return pipe, affecting the normal operation of the equipment, and requiring frequent manual cleaning. The support plate 3 and the scraper 4 cooperate, and when part of the liquid falls downward because it is completely adhered to the outer wall of the drum body 1, the scraper 4 and the support plate 3 can guide the part of the liquid to flow downward, avoiding the fallen liquid from being located below the drum body 1. This not only reduces the labor intensity of manual labor, but also avoids the blockage of the trough and the return pipe, thereby improving work efficiency.

[0083] Reference Attachment Figure 2 and Figure 5 The scraper 4 is provided with a plurality of through holes 30 adapted to the adjustment assembly 5, and the adjustment assembly 5 is adapted to rotate within the through holes 30; the support plate 3 is provided with a plurality of sliding grooves 40 corresponding to the through holes 30, and the adjustment assembly 5 is adapted to move within the sliding grooves 40; wherein, when the scraper 4 moves toward the support plate 3, the adjustment member 51 of the adjustment assembly 5 is pushed and rotated by the support plate 3. The adjustment member 51 rotates relative to the scraper 4. At this time, the bolt column 53 is limited by the support plate 3 and cannot rotate. The adjustment disk 52 is adapted to squeeze the scraper 4 to improve the stability between the scraper 4 and the support plate 3. Because the scraper 4 and the support plate 3 are fixed by the threaded engagement of the adjustment member 51 and the bolt column 53, when the scraper 4 scrapes material from the outer wall of the drum body 1, the scraper 4 will vibrate relative to the support plate 3, and the vibration of the scraper 4 will cause the adjustment member 51 to loosen relative to the bolt column 53. Each time the scraper 4 is pushed to move toward the support plate 3 , the adjusting member 51 is rotated and tightened, thereby improving the stability of the fixation between the scraper 4 and the support plate 3 .

[0084] Reference Attachment Figure 4 The adjusting assembly 5 includes: an adjusting member 51, which is rotatably arranged in the through hole 30, and a spiral groove is provided on the inner wall of the adjusting member 51; the diameter of the adjusting member 51 is smaller than the diameter of the through hole 30, and the axial height of the adjusting member 51 is greater than the thickness of the scraper 4. When the adjusting member 51 passes through the through hole 30, the adjusting rack 56 is suitable for engaging with the linear rack 41. An adjusting disk 52 is arranged at the upper end of the adjusting member 51, and the diameter of the adjusting disk 52 is larger than the inner diameter of the through hole 30; a bolt column 53 is slidably arranged in the sliding groove 40, and the outer wall is provided with a spiral pattern adapted to the spiral groove; a lower positioning disk 54 is arranged on the bottom wall of the bolt column 53, and the diameter of the lower positioning disk 54 is larger than the slot width of the sliding groove 40; two limiting columns 55 are symmetrically provided on the upper surface of the lower two-position disk, and the two limiting columns 55 are respectively provided on both sides of the bolt column 53; the bottom wall of the support plate 3 is located on both sides of the sliding groove 40 and is respectively provided with two limiting grooves 32, the limiting grooves 32 are parallel to the sliding groove 40, and the limiting columns 55 are slidably provided in the limiting grooves 32.

[0085] Reference Attachment Figure 7When the scraper 4 is pushed toward the support plate 3 by the hard protrusions on the outer wall of the drum body 1, the scraper 4 drives the adjustment member 51 to slide toward the support plate 3. The adjustment rack 56 on the outer wall of the adjustment member 51 moves relative to the linear rack 41, and the linear rack 41 is suitable for driving the adjustment member 51 to rotate. At this time, the limiting column 55 on the bottom wall of the lower positioning plate 54 is limited by the support plate 3. Therefore, the lower adjustment plate 52 cannot rotate with the adjustment member 51. The adjustment member 51 rotates relative to the bolt column 53, thereby achieving the effect of screwing the scraper 4. The adjustment member 51 is suitable for rotating relative to the scraper 4, and the adjustment disk 52 is suitable for squeezing the scraper 4 toward the lower positioning plate 54. The adjustment member 51, the adjustment disk 52, the lower positioning plate 54, and the support plate cooperate to achieve the effect of clamping the scraper 4, preventing the scraper 4 from loosening relative to the support plate 3, and improving the stability between the scraper 4 and the support plate 3.

[0086] Reference Attachment Figure 5 A linear rack 41 is provided on the inner wall of one side of the sliding groove 40, which is adapted to mate with the adjustment member 51. When the scraper 4 slides toward the support plate 3, the linear rack 41 is adapted to drive the adjustment member 51 to rotate in the forward direction. Several adjustment racks 56 are circumferentially hingedly connected to the outer wall of the adjustment member 51, which are adapted to mate with the linear racks 41. When the adjustment member 51 slides relative to the linear rack 41, the linear rack 41 is adapted to push the adjustment racks 56, causing the adjustment member 51 to slide and rotate relative to the linear rack 41. Specifically, when the scraper 4 slides toward the support plate 3, the linear rack 41 drives the adjustment racks 56, causing the adjustment member 51 to rotate in the forward direction.

[0087] Reference Attachment Figure 7 and Figure 8 Preferably, a return spring 42 is provided on the sidewall of the sliding groove 40, one end of which is fixed to the outer wall of the bolt column 53. When the scraper 4 is pushed toward the support plate 3, the bolt column 53 is adapted to squeeze the return spring 42 and compress and deform. When the external force pushing the scraper 4 disappears, the return spring 42 is adapted to push the bolt column 53, causing it to move away from the support plate 3. When the scraper 4 slides away from the support plate 3, the linear rack 41 pushes the adjustment rack 56 to rotate in the direction of the axis of the adjustment member 51 with the hinge point as the axis. At this time, the adjustment rack 56, which is meshed with the linear rack 41, is pushed by the linear rack 41 to rotate in the direction of the axis of the adjustment member 51 when the adjustment member 51 returns relative to the linear rack 41. That is, the adjustment rack 56 is not pushed by the linear rack 41 to cause the adjustment member 51 to rotate, and the adjustment member 51 slides relative to the linear rack 41.

[0088] Reference Attachment Figure 6In order to improve the stability between the scraper 4 and the support plate 3, a buffer sheet 31 is provided between the scraper 4 and the support plate 3. The buffer sheet 31 is sleeved on the outer wall of the adjusting member 51. The buffer sheet 31 is slowed down to prevent the scraper 4 from deforming when squeezed.

[0090] Some embodiments provide a method for operating a scraper 4 dryer, the method comprising:

[0091] When the drum body 1 rotates until the dried material abuts against the scraper 4, the scraper 4 scrapes the material on the outer wall of the drum body 1; when the scraper 4 is pushed by the material protruding from the outer wall of the drum body 1 to move toward the side feeding device 2, the adjusting component 5 rotates relative to the scraper 4, and the adjusting component 5 cooperates with the support plate 3 to press the scraper 4.
