Detailed Description

To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

In order to solve the above technical problem, the present disclosure provides a scraper device, which is applied to a sulfur slicer, fig. 1 is a cross-sectional view of the sulfur slicer equipped with the scraper device, as shown in fig. 1, the scraper device includes a knife rest 1, a scraper 2, and an elastic component 3, and the knife rest 1, the scraper 2, and the elastic component 3 are respectively located in a housing 100 of the sulfur slicer.

The blade holder 1 is intended to be connected to a housing 100 of a sulphur slicer. The scraper 2 comprises a first end and a second end in the length direction, the middle part of the first end and the second end of the scraper 2 is rotatably connected with the knife rest 1, the rotation axis of the scraper 2 is parallel to the rotation axis of the rotary drum 200 of the sulfur slicer, and the first end of the scraper 2 is used for abutting against the peripheral wall of the rotary drum 200 of the sulfur slicer. One portion of the resilient member 3 is adapted to be attached to the housing 100 of the sulfur slicer and another portion is attached to the second end of the scraper blade 2 such that the resilient member 3 is compressed between the housing 100 of the sulfur slicer and the second end of the scraper blade 2.

When solid sulfur on a rotary drum 200 of the sulfur slicer is scraped by the scraper device provided by the embodiment of the disclosure, the elastic component 3 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 with the knife rest 1, so that the first end of the scraper 2 always abuts against the peripheral wall of the rotary drum 200 based on the lever principle, thereby ensuring the efficiency of scraping the solid sulfur. Further, since the first end of the scraper 2 is abutted against the outer circumferential wall of the drum 200 based on the elastic force of the elastic member 3, the force of the scraper 2 against the outer circumferential wall of the drum 200 is not excessive. Even if the drum 200 is jumped, 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 avoid the scraper 2 from damaging the outer circumferential wall of the drum 200. In addition, the elastic force exerted by the elastic component 3 on the scraper 2 is not influenced by the solid sulfur dust.

Therefore, the scraper device provided by the embodiment of the disclosure is not affected by solid sulfur dust, and not only can the scraping efficiency be ensured, but also the rotary drum 200 is not damaged when the scraper device works.

Fig. 2 is a schematic structural diagram of the tool holder, and in conjunction with fig. 2, in the present embodiment, the tool holder 1 includes a support arm 11, a sliding sleeve 12, and two lock nuts 13.

The first end of the support arm 11 is adapted to be connected to a housing 100 of a sulphur slicer. The sliding sleeve 12 is axially movably sleeved on the supporting arm 11 and is close to the second end of the supporting arm 11, and the scraper 2 is rotatably connected with the sliding sleeve 12. Two locking nuts 13 are respectively positioned at two sides of the sliding sleeve 12 and are respectively in threaded fit with the supporting arm 11.

In the above implementation, the supporting arm 11 is vertically arranged perpendicular to the horizontal plane and fixed inside the housing 100 for providing a mounting base for the sliding sleeve 12 and the locking nut 13. Since the sliding sleeve 12 is slidably sleeved on the supporting arm 11, the scraper 2 connected to the sliding sleeve 12 can also move relative to the supporting arm 11, so that the position of the scraper 2 in the vertical direction can be adjusted by moving the scraper 2 along the supporting arm 11, thereby adjusting the angle of the scraper 2 relative to the rotation axis of the rotary drum 200. After the scraper 2 is moved to a proper position, the locking nuts 13 are screwed, so that the locking nuts 13 positioned on two sides of the sliding sleeve 12 are respectively abutted against two sides of the sliding sleeve 12, thereby realizing the positioning of the sliding sleeve 12 and further realizing the positioning of the scraper 2.

Illustratively, the lock nut 13 is an outer hexagonal nut so as to facilitate tightening and loosening of the lock nut 13 by a common wrench.

Since the blade holder 1 needs to provide support for the doctor blade 2, in order to ensure the stability of the support, in this embodiment, the blade holder 1 further includes a reinforcing arm 14, one end of the reinforcing arm 14 is located between the first end and the second end of the supporting arm 11 and is connected to the supporting arm 11, and the other end of the reinforcing arm 14 is used for being connected to the housing 100 of the sulfur slicer.

In the above-described embodiment, the reinforcement arm 14 is arranged obliquely with respect to the support arm 11, so that the reinforcement arm 14 and the support arm 11 together form a triangular frame structure, thereby improving the support stability of the tool holder 1 by virtue of the triangular stability.

The support arm 11, the reinforcement arm 14 and the sliding sleeve 12 are illustratively metallic structural members, thereby ensuring the structural strength of the tool holder 1.

Illustratively, the support arm 11 and the reinforcement arm 14 are welded together, the support arm 11 and the housing 100 are welded together, and the reinforcement arm 14 and the housing 100 are welded together, so that not only the structural strength of the tool holder 1 but also the mounting stability of the tool holder 1 in the housing 100 are ensured.

As can be seen from the foregoing, the scraper blade 2 is rotatably connected to the blade holder 1, and in order to realize the rotatable connection between the scraper blade 2 and the blade holder 1, in the present embodiment, the blade holder 1 further includes a bearing 15, an outer ring of the bearing 15 is connected to the sliding sleeve 12, an inner ring of the bearing 15 is connected to the scraper blade 2, and a rotation axis of the bearing 15 coincides with a rotation axis of the scraper blade 2.

Because the inner ring and the outer ring of the bearing 15 can rotate relatively, the outer ring of the bearing 15 is connected with the sliding sleeve 12, and the inner ring of the bearing 15 is connected with the scraper 2, so that the rotatable connection between the scraper 2 and the sliding sleeve 12, namely the rotatable connection between the scraper 2 and the knife rest 1, can be realized.

In order to avoid that the solid sulfur dust is stuck between the outer ring and the inner ring of the bearing 15 to affect the normal rotation of the bearing 15, the bearing 15 is exemplarily a dust-proof bearing. Therefore, the dust cover between the inner ring and the outer ring of the dust-proof bearing can effectively isolate solid sulfur powder from entering, and the outer ring and the inner ring of the bearing 15 are prevented from being clamped.

With continued reference to fig. 2, in the present embodiment, the doctor blade 2 includes a blade 21, a blade holder 22, and a spindle 23.

The blade 21 is located at a first end of the knife bar 22 and is connected to the knife bar 22. The second end of the knife bar 22 is connected to the elastic assembly 3. The rotating shaft 23 is located between the first end and the second end of the cutter bar 22, one end of the rotating shaft 23 is connected with the cutter bar 22, and the other end of the rotating shaft 23 is coaxially inserted into the inner ring of the bearing 15.

In the above implementation, the knife bar 22 provides a mounting base for the blade 21 and the rotating shaft 23. The rotating shaft 23 is inserted into an inner ring of the bearing 15 to achieve a connection between the cutter bar 22 and the bearing 15, so that the cutter bar 22 can rotate about the rotation axis of the bearing 15. Because the blade 21 is connected with the first end of the cutter bar 22, and the second end of the cutter bar 22 is connected with the elastic component 3, the blade 21 can always keep direct contact with the rotary drum 200 under the action of the elastic component 3, thereby realizing the scraping of the solid sulfur. Moreover, if the rotary drum 200 is jumped, the blade 21 can also generate a self-adaptive movement relative to the rotary drum 200, so as to drive the first end of the cutter bar 22 to move together, so that the second end of the cutter bar 22 reversely compresses the elastic component 3, thereby preventing the scraper 2 from damaging the outer circumferential wall of the rotary drum 200.

Illustratively, the blade 21 is a ZQAL9-4 alloy structural member. ZQAL9-4 is cast aluminum iron bronze, and it not only has higher intensity and antifriction, still has good corrosion resistance, can be effectual the life of assurance blade 21, has avoided the change blade 21 of high frequency.

Optionally, the rotating shaft 23 is located between the first end and the second end of the cutter bar 22 and close to the first end, so that the force arm between the rotating shaft 23 and the elastic component 3 is greater than the force arm between the rotating shaft 23 and the cutter blade 21, thereby ensuring that the acting force exerted on the elastic component 3 is enough to enable the cutter blade 21 to cling to the peripheral wall of the rotary drum 200, so as to ensure high scraping efficiency.

Of course, the position of the rotating shaft 23 on the cutter bar 22 can be adjusted according to actual requirements, which is not limited by the present disclosure.

Illustratively, the rotating shaft 23 and the cutter bar 22 are welded together, so that the structural strength of the scraper 2 is ensured, and the rotating shaft 23 is prevented from being broken due to stress.

Fig. 3 is a schematic structural diagram of the elastic assembly, and referring to fig. 3, in the present embodiment, the elastic assembly 3 includes a shaft body 31 and an elastic member 32.

The first end of the shaft 31 is used for connecting with the housing 100 of the sulfur slicer, the position of the scraper 2 near the second end is provided with an elongated hole 24, the length direction of the hole 24 is the same as that of the scraper 2, and the second end of the shaft 31 is movably inserted in the hole 24. The elastic member 32 is disposed on the shaft 31, and has a portion connected to the first end of the shaft 31 and another portion 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.

In the above implementation, the shaft body 31 is vertically arranged perpendicular to the horizontal plane and fixed inside the housing 100, which not only can provide a mounting base for the elastic member 32, but also can provide a guide for the movement of the second end of the scraper 2. It will be readily understood that the second end of the scraper 2 is moved in a circular manner about the axis of rotation of the scraper 2, rather than completely along the axial direction of the shaft body 31. Therefore, through the hole 24, a space can be provided for the radial movement of the second end of the scraper 2 relative to the shaft body 31, and the interference between the scraper 2 and the shaft body 31 is avoided. Of course, the bore 24 at the second end of the blade 2 is located at the second end of the blade bar 22.

The elastic member 32 is illustratively a coil spring and coaxially fitted over the shaft body 31. The elastic member 32 has one end connected to the first end of the shaft body 31 and the housing 100 and the other end connected to the second end of the scraper 2, i.e., the second end of the blade bar 22. Under the action of the elastic element 32, the knife bar 22 always tends to rotate counterclockwise (with reference to fig. 1), so that the first end of the knife bar 22 carries the blade 21 to always abut against the outer circumferential wall of the drum 200.

In order to prevent the elastic member 32 from pushing the second end of the arbor 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, so that the second end of the arbor 22 does not come off.

Illustratively, the elastic assembly 3 further comprises an adjustment nut 33.

The adjusting nut 33 is sleeved on one side of the scraper 2, which is far away from the elastic element 32, and the adjusting nut 33 is sleeved on the shaft body 31 and is in threaded fit with the shaft body 31.

In the above implementation, by adjusting the nut 33, the maximum length of extension of the elastic member 32 can be limited, thereby limiting the maximum distance that the first end of the knife bar 22 is pressed down toward the outer circumferential wall of the drum 200. It will be readily appreciated that the closer the adjustment nut 33 is to the first end of the shaft body 31, the smaller the maximum length of extension of the elastic member 32 and the smaller the maximum distance the first end of the knife bar 22 is depressed toward the outer peripheral wall of the drum 200.

Illustratively, the adjustment nut 33 is an outer hexagonal nut to facilitate tightening and loosening of the adjustment nut 33 by a conventional wrench

It is easily understood that in other embodiments, the elastic assembly 3 can also have only the elastic member 32 without the shaft body 31 and the adjustment nut 33 for saving the manufacturing cost. In this case, a portion of the elastic member 32 is connected to the housing 100, and another portion of the elastic member 32 is connected to the knife bar 22. Because the elastic member 32 has a certain bending deformation capability, the hole 24 on the scraper 2 is not needed, and the cutter bar 22 is directly connected with the elastic member 32.

With continued reference to fig. 1, embodiments of the present disclosure provide a sulfur slicer that includes a housing 100, a drum 200, and a scraper device 300.

The housing 100 includes a frame 110 and a cover 120, and the frame 110 and the cover 120 are detachably coupled to form an accommodating space. The drum 200 is rotatably disposed in the accommodating space. The scraper device 300 is the aforementioned scraper device 300, the scraper device 300 is located in the accommodating space and connected to the frame 110, and the scraper 2 of the scraper device 300 abuts against the outer circumferential wall of the drum 200.

When solid sulfur is produced by the sulfur slicer provided by the embodiment of the present disclosure, the drum 200 crystallizes the liquid sulfur to be converted into solid sulfur, and adheres to the outer circumferential wall of the drum 200 to rotate together with the drum 200. Because 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 with the knife rest 1, based on the lever principle, the first end of the scraper 2 always abuts against the peripheral wall of the rotary drum 200, so as to ensure efficient scraping of the solid sulfur on the peripheral wall of the rotary drum 200. Further, since the first end of the scraper 2 is abutted against the outer circumferential wall of the drum 200 based on the elastic force of the elastic member 3, the force of the scraper 2 against the outer circumferential wall of the drum 200 is not excessive. Even if the drum 200 is jumped, 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 avoid the scraper 2 from damaging the outer circumferential wall of the drum 200. In addition, the elastic force exerted by the elastic component 3 on the scraper 2 is not influenced by the solid sulfur dust.

Therefore, the sulfur slicer provided by the embodiment of the disclosure is not affected by solid sulfur dust, and not only can the scraping efficiency be ensured, but also the rotary drum 200 cannot be damaged during operation.

In this embodiment, the sulfur slicer further comprises a discharging channel 400, the discharging channel 400 is arranged obliquely relative to the horizontal plane, one end of the discharging channel 400 is connected with the accommodating space, and the other end of the discharging channel 400 is connected with the storage bin. So design for the solid-state sulphur that is scraped off by scraper device 300 can directly fall into the storehouse of storing along unloading passageway 400, so that the storage packing.

Illustratively, to facilitate the solid sulfur to fall into the blanking channel 400, the scraper device 300 is located at the junction between the blanking channel 400 and the housing 100.

The above description is intended to be exemplary only and not to limit the present disclosure, and any modification, equivalent replacement, or improvement made without departing from the spirit and scope of the present disclosure is to be considered as the same as the present disclosure.
