Description

Technical Field

[0001] The present invention belongs to the field of mechanical technology, and in particular relates to a scraper device and a sulfur slicer. Background Art

[0002] The sulfur slicer is a mechanical device used to crystallize liquid sulfur into solid sulfur. It mainly includes a housing, a drum and a scraper device. The drum and the scraper device are respectively located in the housing. The drum rotates relative to the housing and the scraper, and the scraper device contacts the outer peripheral wall of the drum. When the sulfur slicer is working, the drum rotates, and the liquid sulfur quickly crystallizes into solid sulfur after contacting the drum and adheres to the outer peripheral wall of the drum. The attached solid sulfur rotates with the drum until it contacts the scraper device and is scraped off by the scraper device.

[0003] The relative position between the scraper device and the drum is an important factor affecting the working efficiency of the sulfur slicer. If the scraper device is too close to the drum, the drum will be scratched. If the scraper device is too far from the drum, the efficiency of scraping off the solid sulfur will be too low. In the related art, in order to solve this problem, the scraper device usually includes a blade, an adjusting nut and an adjusting screw. The blade is connected to the adjusting nut, and the adjusting nut is threadedly matched with the adjusting screw. The relative rotation between the adjusting screw and the adjusting nut makes the adjusting nut move axially relative to the adjusting screw, so as to adjust the relative position between the blade and the drum.

[0004] However, a large amount of sulfur dust is generated when scraping solid sulfur. The sulfur dust will be stuck between the adjusting nut and the adjusting screw, making it impossible for the adjusting screw and the adjusting nut to rotate relative to each other normally, resulting in the relative position between the blade and the drum being unable to be adjusted normally, affecting the working efficiency of the sulfur slicer.

[0044] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0045] The sulfur slicer is a mechanical device used to crystallize liquid sulfur into solid sulfur. It mainly includes a housing, a drum and a scraper device. The drum and the scraper device are respectively located in the housing. The drum rotates relative to the housing and the scraper, and the scraper device contacts the outer peripheral wall of the drum. When the sulfur slicer is working, the drum rotates, and the liquid sulfur quickly crystallizes into solid sulfur after contacting the drum and adheres to the outer peripheral wall of the drum. The attached solid sulfur rotates with the drum until it contacts the scraper device and is scraped off by the scraper device.

[0046] The relative position between the scraper device and the drum is an important factor affecting the working efficiency of the sulfur slicer. If the scraper device is too close to the drum, the drum will be scratched. If the scraper device is too far from the drum, the efficiency of scraping off the solid sulfur will be too low. In the related art, in order to solve this problem, the scraper device usually includes a blade, an adjusting nut and an adjusting screw. The blade is connected to the adjusting nut, and the adjusting nut is threadedly matched with the adjusting screw. The relative rotation between the adjusting screw and the adjusting nut makes the adjusting nut move axially relative to the adjusting screw, so as to adjust the relative position between the blade and the drum.

[0047] However, a large amount of sulfur dust is generated when scraping solid sulfur. The sulfur dust will be stuck between the adjusting nut and the adjusting screw, making it impossible for the adjusting screw and the adjusting nut to rotate relative to each other normally, resulting in the relative position between the blade and the drum being unable to be adjusted normally, affecting the working efficiency of the sulfur slicer.

[0048] In order to solve the above technical problems, the present disclosure provides a scraper device, which is applied to a sulfur slicer. Figure 1 The cross-sectional view of the sulphur slicer equipped with the scraper device is shown in FIG. Figure 1 As shown, the scraper device comprises a blade holder 1, a scraper 2 and an elastic component 3, and the blade holder 1, the scraper 2 and the elastic component 3 are respectively located in a housing 100 of the sulfur slicer.

[0049] The tool holder 1 is used to be connected to the housing 100 of the sulfur slicer. The scraper 2 includes a first end and a second end in the length direction. The portion between the first end and the second end of the scraper 2 is rotatably connected to the tool holder 1, and the rotation axis of the scraper 2 is parallel to the rotation axis of the drum 200 of the sulfur slicer. The first end of the scraper 2 is used to abut against the outer peripheral wall of the drum 200 of the sulfur slicer. A part of the elastic component 3 is used to be connected to the housing 100 of the sulfur slicer, and the other part is connected to the second end of the scraper 2, so that the elastic component 3 is compressed between the housing 100 of the sulfur slicer and the second end of the scraper 2.

[0050] When the scraper device provided by the embodiment of the present disclosure is used to scrape the solid sulfur on the drum 200 of the sulfur slicer, since the elastic component 3 is compressed between the housing 100 of the sulfur slicer and the second end of the scraper 2, and the portion between the first end and the second end of the scraper 2 is rotatably connected to the tool holder 1, based on the lever principle, the first end of the scraper 2 will always be against the outer peripheral wall of the drum 200 to ensure the efficiency of scraping the solid sulfur. In addition, since the first end of the scraper 2 is against the outer peripheral wall of the drum 200 based on the elastic force of the elastic component 3, the force of the scraper 2 on the outer peripheral wall of the drum 200 will not be too large. Even if the drum 200 jumps, the first end of the scraper 2 can also produce an adaptive movement relative to the drum 200, so that the second end of the scraper 2 reversely compresses the elastic component 3 to avoid the scraper 2 from damaging the outer peripheral wall of the drum 200. In addition, the elastic force applied by the elastic component 3 to the scraper 2 will not be affected by the solid sulfur dust.

[0051] It can be seen that the scraper device provided in the embodiment of the present disclosure is not affected by solid sulfur dust, and when working, it can not only ensure the scraping efficiency, but also will not damage the drum 200.

[0052] Figure 2 The schematic diagram of the tool holder is shown in Figure 2. Figure 2 In this embodiment, the tool holder 1 includes a support arm 11 , a sliding sleeve 12 and two locking nuts 13 .

[0053] The first end of the support arm 11 is used to be connected to the housing 100 of the sulfur slicer. The sleeve 12 is axially movably sleeved on the support arm 11, and the scraper 2 is rotatably connected to the sleeve 12 near the second end of the support arm 11. Two locking nuts 13 are respectively located on both sides of the sleeve 12 and are respectively threadedly matched with the support arm 11.

[0054] In the above implementation, the support arm 11 is arranged vertically perpendicular to the horizontal plane and fixed inside the housing 100, so as to provide an installation base for the sleeve 12 and the locking nut 13. Since the sleeve 12 is slidably mounted on the support arm 11, the scraper 2 connected to the sleeve 12 can also move relative to the support arm 11. In this way, the position of the scraper 2 in the vertical direction can be adjusted by moving the scraper 2 along the support arm 11, thereby adjusting the angle of the scraper 2 relative to the rotation axis of the drum 200. After the scraper 2 is moved to a suitable position, the locking nut 13 is screwed so that the locking nuts 13 on both sides of the sleeve 12 are respectively against the two sides of the sleeve 12, thereby realizing the positioning of the sleeve 12, and then realizing the positioning of the scraper 2.

[0055] Exemplarily, the locking nut 13 is an external hexagonal nut, so that the locking nut 13 can be tightened or loosened by a common wrench.

[0056] Since the tool holder 1 needs to provide support for the scraper 2, in order to ensure the stability of the support, in this embodiment, the tool holder 1 also includes a reinforcing arm 14, one end of the reinforcing arm 14 is located between the first end and the second end of the support arm 11 and is connected to the support arm 11, and the other end of the reinforcing arm 14 is used to be connected to the housing 100 of the sulfur slicer.

[0057] In the above implementation, the reinforcing arm 14 is arranged obliquely relative to the supporting arm 11 , so that the reinforcing arm 14 and the supporting arm 11 together form a triangular frame structure, thereby utilizing the stability of the triangle to improve the support stability of the tool holder 1 .

[0058] Exemplarily, the support arm 11 , the reinforcing arm 14 and the sliding sleeve 12 are all metal structural parts, thereby ensuring the structural strength of the tool holder 1 .

[0059] Exemplarily, the support arm 11 and the reinforcing arm 14 are welded together, the support arm 11 and the shell 100 are welded together, and the reinforcing arm 14 and the shell 100 are welded together, thereby ensuring not only the structural strength of the tool holder 1 but also the installation stability of the tool holder 1 in the shell 100.

[0060] As can be seen from the foregoing, the scraper 2 is rotatably connected to the tool holder 1. In order to achieve a rotatable connection between the scraper 2 and the tool holder 1, in this embodiment, the tool holder 1 also includes a bearing 15, the outer ring of the bearing 15 is connected to the sleeve 12, the inner ring of the bearing 15 is connected to the scraper 2, and the rotation axis of the bearing 15 coincides with the rotation axis of the scraper 2.

[0061] Since the inner ring and outer ring of the bearing 15 can rotate relative to each other, the outer ring of the bearing 15 is connected to the sleeve 12, and the inner ring of the bearing 15 is connected to the scraper 2, so that a rotatable connection between the scraper 2 and the sleeve 12, that is, a rotatable connection between the scraper 2 and the tool holder 1 can be achieved.

[0062] In order to prevent the solid sulfur dust from getting stuck between the outer ring and the inner ring of the bearing 15 and affecting the normal rotation of the bearing 15, the bearing 15 is illustratively a dustproof bearing. In this way, the dustproof cover between the inner ring and the outer ring of the dustproof bearing can effectively isolate the solid sulfur powder from entering, thereby preventing the outer ring and the inner ring of the bearing 15 from getting stuck.

[0063] Continue to see Figure 2 In this embodiment, the scraper 2 includes a blade 21, a blade rod 22 and a rotating shaft 23.

[0064] The blade 21 is located at the first end of the knife rod 22 and connected to the knife rod 22. The second end of the knife rod 22 is connected to the elastic component 3. The rotating shaft 23 is located between the first end and the second end of the knife rod 22, and one end of the rotating shaft 23 is connected to the knife rod 22, and the other end of the rotating shaft 23 is coaxially inserted into the inner ring of the bearing 15.

[0065] In the above implementation, the shank 22 provides a mounting base for the blade 21 and the rotating shaft 23. The rotating shaft 23 is inserted into the inner ring of the bearing 15 to realize the connection between the shank 22 and the bearing 15, so that the shank 22 can rotate around the rotating axis of the bearing 15. Since the blade 21 is connected to the first end of the shank 22 and the second end of the shank 22 is connected to the elastic component 3, under the action of the elastic component 3, the blade 21 can always maintain direct contact with the drum 200, thereby achieving scraping of solid sulfur. In addition, if the drum 200 jumps, the blade 21 can also produce adaptive movement relative to the drum 200, driving the first end of the shank 22 to move together, so that the second end of the shank 22 reversely compresses the elastic component 3 to prevent the scraper 2 from damaging the outer peripheral wall of the drum 200.

[0066] For example, the blade 21 is a ZQAL9-4 alloy structure. ZQAL9-4 is a cast aluminum-iron bronze, which not only has high strength and friction reduction, but also has good corrosion resistance, which can effectively ensure the service life of the blade 21 and avoid high-frequency replacement of the blade 21.

[0067] Optionally, the rotating shaft 23 is located between the first end and the second end of the knife rod 22, and is close to the first end. In this way, the force arm between the rotating shaft 23 and the elastic component 3 can be greater than the force arm between the rotating shaft 23 and the blade 21, thereby ensuring that the force applied by the elastic component 3 is sufficient to make the blade 21 close to the outer wall of the drum 200, so as to ensure higher scraping efficiency.

[0068] Of course, the position of the rotating shaft 23 on the knife rod 22 can be adjusted according to actual needs, and the present disclosure does not impose any restrictions on this.

[0069] Exemplarily, the rotating shaft 23 and the blade rod 22 are welded together, thereby ensuring the structural strength of the scraper 2 and preventing the rotating shaft 23 from breaking due to stress.

[0070] Figure 3 is a schematic diagram of the structure of the elastic component, see Figure 3 In this embodiment, the elastic component 3 includes a shaft 31 and an elastic member 32 .

[0071] The first end of the shaft body 31 is used to be connected to the housing 100 of the sulfur slicer, and the scraper 2 has a long hole 24 near the second end. The length direction of the hole 24 is the same as the length direction of the scraper 2. The second end of the shaft body 31 can be movably inserted into the hole 24. The elastic member 32 is sleeved on the shaft body 31, and a part of it is connected to the first end of the shaft body 31, and the other part is connected to the second end of the scraper 2, so as to be compressed between the housing 100 of the sulfur slicer and the second end of the scraper 2.

[0072] In the above implementation, the shaft body 31 is arranged vertically perpendicular to the horizontal plane and fixed inside the housing 100, which can not only provide a mounting base for the elastic member 32, but also provide a guide for the movement of the second end of the scraper 2. It is easy to understand that when the second end of the scraper 2 moves, it is equivalent to moving in a circle with the axis of rotation of the scraper 2 as the axis, rather than moving completely along the axial direction of the shaft body 31. Therefore, through the hole 24, space can be provided for the radial movement of the second end of the scraper 2 relative to the shaft body 31, avoiding interference between the scraper 2 and the shaft body 31. Of course, the hole 24 located at the second end of the scraper 2 is located at the second end of the shank 22.

[0073] For example, the elastic member 32 is a coil spring and is coaxially sleeved outside the shaft body 31. One end of the elastic member 32 is connected to the first end of the shaft body 31 and the housing 100, and the other end is connected to the second end of the scraper 2, that is, connected to the second end of the knife rod 22. Under the action of the elastic member 32, the knife rod 22 always rotates counterclockwise (in degrees). Figure 1 As a reference), the first end of the knife rod 22 drives the blade 21 to always contact the outer wall of the rotating drum 200.

[0074] It should be noted that in order to prevent the elastic member 32 from pushing the second end of the knife rod 22 out of the shaft body 31, the length of the shaft body 31 needs to be long enough, for example, longer than the length of the elastic member 32 in the natural state, to ensure that the second end of the knife rod 22 will not fall out.

[0075] Exemplarily, the elastic component 3 further includes an adjusting nut 33 .

[0076] The adjusting nut 33 is sleeved on a side of the scraper 2 away from the elastic member 32 . The adjusting nut 33 is sleeved on the shaft body 31 and threadably matched with the shaft body 31 .

[0077] In the above implementation, the maximum length of the elastic member 32 can be limited by adjusting the nut 33, thereby limiting the maximum distance that the first end of the knife rod 22 is pressed toward the outer peripheral wall of the rotating drum 200. It is easy to understand that the closer the adjusting nut 33 is to the first end of the shaft body 31, the smaller the maximum length of the elastic member 32, and the smaller the maximum distance that the first end of the knife rod 22 is pressed toward the outer peripheral wall of the rotating drum 200.

[0078] Exemplarily, the adjusting nut 33 is an external hexagonal nut, so that the adjusting nut 33 can be tightened and loosened by a common wrench.

[0079] It is easy to understand that in other embodiments, in order to save manufacturing costs, the elastic component 3 can also only have the elastic member 32, without the shaft 31 and the adjusting nut 33. In this case, a part of the elastic member 32 is connected to the housing 100, and the other part of the elastic member 32 is connected to the knife bar 22. Since the elastic member 32 has a certain bending deformation ability, it is not necessary to set the hole 24 on the scraper 2, and the knife bar 22 can be directly connected to the elastic member 32.

[0080] Continue to see Figure 1 An embodiment of the present disclosure provides a sulfur slicer, which includes a housing 100, a rotating drum 200 and a scraper device 300.

[0081] The housing 100 includes a frame 110 and a cover 120, and the frame 110 and the cover 120 are detachably connected to form a receiving space. The rotating drum 200 is rotatably located in the receiving space. The scraper device 300 is the scraper device 300 described above, and the scraper device 300 is located in the receiving space and connected to the frame 110. The scraper 2 of the scraper device 300 abuts against the outer peripheral wall of the rotating drum 200.

[0082] When solid sulfur is manufactured by the sulfur slicer provided by the embodiment of the present disclosure, the rotary drum 200 crystallizes liquid sulfur to convert it into solid sulfur, and the solid sulfur is attached to the outer peripheral wall of the rotary drum 200 and rotates with the rotary drum 200. Since the elastic component 3 of the scraper device 300 is compressed between the housing 100 of the sulfur slicer and the second end of the scraper 2, and the middle part of the first end and the second end of the scraper 2 is rotatably connected to the tool holder 1, based on the lever principle, the first end of the scraper 2 will always be against the outer peripheral wall of the rotary drum 200 to ensure efficient scraping of the solid sulfur on the outer peripheral wall of the rotary drum 200. In addition, since the first end of the scraper 2 is against the outer peripheral wall of the rotary drum 200 based on the elastic force of the elastic component 3, the force of the scraper 2 on the outer peripheral wall of the rotary drum 200 will not be too large. Even if the drum 200 jumps, the first end of the scraper 2 can generate adaptive movement relative to the drum 200, so that the second end of the scraper 2 reversely compresses the elastic component 3 to prevent the scraper 2 from damaging the outer peripheral wall of the drum 200. In addition, the elastic force applied by the elastic component 3 to the scraper 2 will not be affected by the solid sulfur dust.

[0083] It can be seen that the sulfur slicer provided in the embodiment of the present disclosure is not affected by solid sulfur dust. When working, it can not only ensure the scraping efficiency, but also will not cause damage to the drum 200.

[0084] In this embodiment, the sulfur slicer further includes a feeding channel 400, which is arranged obliquely relative to the horizontal plane, one end of which is connected to the accommodating space, and the other end of which is connected to the storage bin. With such a design, the solid sulfur scraped off by the scraper device 300 can directly fall into the storage bin along the feeding channel 400 for easy storage and packaging.

[0085] Exemplarily, in order to facilitate the solid sulfur to fall into the feeding channel 400 , the scraper device 300 is located at the connection between the feeding channel 400 and the housing 100 .

[0086] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
