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 upgrading, the waste liquid treated today generally shows 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 the actual use needs.

[0003] Therefore, side spray feeding has become the trend of equipment feeding method 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 being dried, relatively hard bumps will be formed on the outer wall of the drum dryer. At this time, adjusting the scraper to directly contact the bumps will damage the scraper's cutting edge, 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, the scraper is generally set on the support plate for sliding. After being squeezed by the protrusions on the outer wall of the drum dryer, the scraper slides away from the drum dryer to prevent the scraper blade from being damaged by hard materials. However, the scraper slides relative to the support plate, and its stability becomes poor. At the same time, after multiple sliding resets, the distance between the scraper and the outer wall of the drum dryer will increase compared to the preset distance. As the scraper slides relative to the support plate, its fixing bolts will become loose, causing the scraper to tilt, and the increase in the distance will make it impossible for the scraper to cleanly scrape the material on the outer wall of the drum dryer.

[0006] Therefore, how to avoid the scraper being unable to scrape the material on 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 needs to be solved urgently in the 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.

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are 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.

[0028] In this article, when it is mentioned that the first component is located on the second component, this may mean that the first component may be directly formed on the second component, or the third component may be interposed between the first component and the second component. In addition, in the drawings, in order to effectively describe the technical content, the thickness of the components may be exaggerated or reduced.

[0029] 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..." modify the entire list of elements when following a 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.

[0030] The terms used herein are only used to describe specific exemplary configurations and are not intended to be limited. As used herein, the singular articles "one", "an" and "the" may also be intended to include plural forms, unless it is clearly indicated above that this is not the case.

[0031] 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. Therefore, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, so that these phrases do not necessarily refer to the same embodiment.

On the contrary, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0032] After research, it was found that the shortcomings of the existing technology are: for liquid material with special properties, after it is dried, a relatively hard bulge will be formed on the outer wall of the drum dryer. At this time, adjusting the scraper to directly contact the bulge will damage the cutting edge of the scraper, causing the cutting edge to be broken, thereby affecting the effect of the scraper scraping the material on the outer wall of the drum dryer.

[0033] In the related art, the scraper is usually set on the support plate for sliding. After being squeezed by the protrusions on the outer wall of the drum dryer, the scraper slides away from the drum dryer to prevent the scraper blade from being damaged by hard materials. However, the stability of the scraper becomes poor as it slides relative to the support plate. At the same time, after multiple sliding resets, the distance between the scraper and the outer wall of the drum dryer will increase compared to the preset distance. As the scraper slides relative to the support plate, its fixing bolts will become loose, causing the scraper to tilt. The increase in the distance will cause the scraper to be unable to cleanly scrape the material on the outer wall of the drum dryer.

[0034] Therefore, how to avoid the increase in the distance between the scraper and the outer wall of the drum dryer due to the deterioration of the stability of the scraper when sliding is a technical problem that needs to be solved urgently in this field.

[0035] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0036] 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, further definition and explanation thereof is not required in subsequent drawings.

[0037] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] like Figures 1 to 8As 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 driving motor is arranged on one side of the base, and the roller body 1 is drivingly connected to the driving motor. Preferably, the interior of the roller body 1 is hollow, and an air inlet pipe is arranged on the side of the roller body 1 close to the driving motor, and the air inlet pipe is suitable for conveying high-temperature steam into the roller body 1. Furthermore, a heating coil can also be arranged in the roller body 1 to heat the roller body 1. A side loading device 2 is arranged on one side of the roller body 1; a plurality of spray holes are opened 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 feeding device 2 and is inclined; the scraper 4 is parallel to the outer wall of the drum body 1; a plurality of adjustment components 5 are arranged on the scraper 4 at equal intervals and are suitable for connecting the support plate 3 and the scraper 4; wherein, 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 adjustment component 5 rotates relative to the scraper 4, and the adjustment component 5 cooperates with the support plate 3 to press the scraper 4. Through the cooperation of the adjustment component 5, the scraper 4 and the support plate 3, when the scraper 4 slides toward the support plate 3, the adjustment component 5 cooperates with the support plate 3 to clamp the scraper 4, so as to prevent the scraper 4 from loosening relative to the support plate 3 during the sliding process, thereby improving the stability of the scraper 4 and avoiding the increase of the gap between the scraper 4 and the drum body 1. When the scraper 4 slides toward the drum body 1, the adjusting assembly 5 does not rotate, but only rotates synchronously with the scraper 4, thereby preventing the scraper 4 from loosening when it slides back.

[0039] When the side loading device 2 transports the liquid to the side wall of the drum body 1, some of the materials that are 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, so that the supersaturated liquid evaporates and crystallizes in the trough for the second time, 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, 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. Not only does it reduce the labor intensity of manual labor, but it also avoids the blockage of the trough and the return pipe, thereby improving work efficiency.

[0040] Reference 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 in 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 in 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 which time, the bolt column 53 is limited by the support plate 3 and cannot rotate, and the adjustment disk 52 is adapted to squeeze the scraper 4 to improve the stability between the scraper 4 and the support plate 3. Since the scraper 4 and the support plate 3 are fixed by the threaded matching of the adjustment member 51 and the bolt column 53, when the scraper 4 scrapes the material on the outer wall of the drum body 1, the scraper 4 will shake relative to the support plate 3, and the shaking 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 .

[0041] Reference 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 matched with 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 arranged on the upper surface of the lower two-position disk, and the two limiting columns 55 are respectively arranged 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 arranged in the limiting grooves 32.

[0042] Reference Figure 7When the scraper 4 is pushed by the hard protrusions on the outer wall of the drum body 1 to move toward the support plate 3, the scraper 4 drives the adjusting member 51 to slide in the direction of the support plate 3, and the adjusting rack 56 on the outer wall of the adjusting member 51 moves relative to the linear rack 41, and the linear rack 41 is suitable for pushing the adjusting 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, so the lower adjusting plate 52 cannot rotate with the adjusting member 51, and the adjusting member 51 rotates relative to the bolt column 53, thereby achieving the effect of screwing the scraper 4, the adjusting member 51 is suitable for rotating relative to the scraper 4, and the adjusting plate 52 is suitable for squeezing the scraper 4 to move in the direction of the lower positioning plate 54. The adjustment member 51, the adjusting plate 52 cooperate with the lower positioning plate 54 and the support plate to achieve the effect of clamping the scraper 4, avoiding the occurrence of looseness of the scraper 4 relative to the support plate 3, and improving the stability between the scraper 4 and the support plate 3.

[0043] Reference Figure 5 , a linear rack 41 matched with the adjusting member 51 is arranged on the inner wall of one side of the sliding groove 40. When the scraper 4 slides toward the supporting plate 3, the linear rack 41 is suitable for driving the adjusting member 51 to rotate in the positive direction. A plurality of adjusting racks 56 matched with the linear rack 41 are circumferentially hinged on the outer wall of the adjusting member 51; when the adjusting member 51 slides relative to the linear rack 41, the linear rack 41 is suitable for pushing the adjusting rack 56 to make the adjusting member 51 slide and rotate relative to the linear rack 41. Among them, when the scraper 4 slides toward the supporting plate 3, the linear rack 41 drives the adjusting rack 56 to make the adjusting member 51 rotate in the positive direction.

[0044] Reference Figure 7 and Figure 8 Preferably, a return spring 42 is provided on the side wall of the sliding groove 40, and one end of the return spring 42 is fixed to the outer wall of the bolt column 53. When the scraper 4 is pushed to move in the direction of the support plate 3, the bolt column 53 is suitable for squeezing the return spring 42 to compress and deform. When the external force pushing the scraper 4 disappears, the return spring 42 is suitable for pushing the bolt column 53 to move away from the support plate 3. When the scraper 4 slides in the direction away from the support plate 3, the linear rack 41 pushes the adjustment rack 56 to flip in the axial direction of the adjustment member 51 with the hinge point as the axial direction. At this time, the adjustment rack 56 meshed with the linear rack 41 is pushed by the linear rack 41 to flip in the axial direction of the adjustment member 51 when the adjustment member 51 is reset relative to the linear rack 41, that is, the adjustment rack 56 will not be pushed by the linear rack 41 to drive the adjustment member 51 to rotate, and the adjustment member 51 slides relative to the linear rack 41.

[0045] Reference 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 used to slow down the deformation of the scraper 4 when it is squeezed.
