Description

Technical Field

[0001] This utility model relates to the field of sulfur weighing technology, specifically a weighing device for the proportioning of sulfur products. Background Technology

[0002] Sulfur is a pale yellow, brittle crystal or powder with a distinctive odor. It is also known as sulfur, colloidal sulfur, or sulfur lumps. Sulfur is insoluble in water, slightly soluble in ethanol and ether, and readily soluble in carbon disulfide. As an industrial raw material, sulfur is widely used in chemical, light industrial, pesticide, rubber, dye, and paper industries. Sulfur contains a large amount of arsenic, which can easily cause renal insufficiency and failure, polyneuritis, and liver damage. Oral ingestion is strictly prohibited. Because sulfur combines with oxygen to produce sulfur dioxide, which has bleaching properties, and because sulfur also has bactericidal effects, it can be used to prevent food spoilage and extend shelf life.

[0003] Patent document CN208135899U discloses an automatic sulfur-adding device. This device uses a first measuring element to weigh the sulfur in the sulfur hopper and a second measuring element to weigh the sulfur in the intermediate hopper. By comparing the weighing values ​​of the first and second measuring elements, the amount of sulfur added is ensured. A controller is used to control the opening and closing of the first pneumatic valve at the outlet of the intermediate hopper, thereby automatically controlling the liquid level in the sulfur hexafluoride reactor. This automatic sulfur-adding device can accurately weigh the amount of sulfur added, thus reducing the quality difference between batches of sulfur hexafluoride.

[0004] However, research has revealed certain drawbacks in the use of existing automatic sulfur-adding devices:

[0005] The first measuring device is used to weigh the sulfur in the sulfur hopper, and the second measuring device is used to weigh the intermediate hopper. This method determines whether there is any missing or insufficient weighing values ​​from the first and second measuring devices, which can accurately add sulfur in subsequent processes. However, in actual applications, if the value weighed by the second measuring device cannot supplement the value weighed by the first measuring device, it can be determined that there is a loss when discharging from the sulfur hopper to the intermediate hopper. Therefore, when discharging from the intermediate hopper, it is difficult to ensure that the final amount of sulfur used is the same as the amount of sulfur weighed by the second measuring device. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, this application provides a weighing device for sulfur product proportioning. By machining an overlapping ring on the outer wall of the weighing hopper, multiple weighing devices are installed between the fixed ring frame mounted on the top of the platform and the overlapping ring. This device can weigh the sulfur added inside the weighing hopper. When the rotary actuator controls the switching plate to rotate, causing the edge of the switching plate to detach from the bottom of the weighing hopper, the sulfur can be completely released to the bottom, minimizing sulfur residue in the connection area between the weighing hopper and the switching plate. This achieves the same technical effect as the amount of sulfur ultimately used, which is the same as the amount of sulfur weighed by the second measuring device in the prior art.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0008] A weighing device for proportioning sulfur products includes a weighing hopper, a fixed ring frame, a weighing device, and a switching sealing plate. An overlapping ring is machined on the outer wall of the middle part of the weighing hopper.

[0009] The fixing ring frame is set at the bottom of the overlapping ring;

[0010] There are multiple weighing devices; and

[0011] The switching sealing plate is rotated and connected to one side of the bottom of the weighing hopper;

[0012] A rotary actuator is assembled and connected to the center of the switching plate. A frustum sleeve is coaxially arranged at the bottom of the weighing hopper. A C-shaped groove is machined inside the frustum sleeve. Lugs are welded to the outer wall of the frustum sleeve. The rotary actuator is assembled to the bottom of the lugs and drives the switching plate located at the top of the lugs to rotate inside the C-shaped groove, so that sulfur is controlled to fall from the bottom of the weighing hopper around the switching plate.

[0013] Preferably, the bottom of the fixed ring frame is assembled with a support platform, and the top of the fixed ring frame is integrally formed with multiple guide rods; the weighing hopper is movably connected to the outside of the multiple guide rods through overlapping rings, keeping the weighing hopper and the fixed ring frame in a coaxial state, while the weighing device is supported between the overlapping rings and the fixed ring frame.

[0014] Preferably, the top of the fixed ring frame is machined with multiple circular grooves, and the multiple weighing devices are respectively assembled into the interior of the multiple circular grooves, with their tops protruding from the top surface of the fixed ring frame.

[0015] Preferably, the top outer walls of both sides of the frustum sleeve are welded with pipe seats, and the bottom of both sides of the erection platform are welded with two fixed seats with round holes. The frustum sleeve is fixed to the bottom of the weighing hopper by passing a round groove through the interior of the two coaxial fixed seats and one pipe seat.

[0016] Preferably, the two tube seats are symmetrically arranged on both sides of the C-shaped groove, and the frustum sleeve is coaxially sleeved to the bottom of the weighing hopper.

[0017] Preferably, an adjusting ring is slidably connected to the inner side of the bottom of the weighing hopper, the bottom cross-section of the weighing hopper is an isosceles trapezoid, the adjusting ring is adapted to be connected inside the weighing hopper, and when the bottom end face of the adjusting ring is flush with the bottom end face of the weighing hopper, a complete frustum tube is formed.

[0018] Preferably, both sides of the bottom of the weighing hopper are machined with strip grooves, and a screw is provided inside each of the two strip grooves. One end of the screw is threadedly connected to the inside of the adjusting ring.

[0019] Preferably, the bottom end face of the adjusting ring is in contact with the top surface of the switching sealing plate. Sulfur is filled inside the weighing hopper and weighed by multiple weighing devices. While maintaining a small downward movement trend, the weighing hopper moves downward outside the adjusting ring.

[0020] In summary, this utility model has at least one of the following beneficial technical effects:

[0021] Firstly, this utility model discloses a weighing device for sulfur product proportioning. By processing overlapping rings on the outer wall of the weighing hopper, multiple weighing devices are set between the fixed ring frame assembled on the top of the platform and the overlapping rings. This device can weigh the sulfur put into the weighing hopper. When the rotary actuator controls the switching plate to rotate, so that the edge of the switching plate separates from the bottom of the weighing hopper, the sulfur can be completely released to the bottom, minimizing the possibility of sulfur residue in the connection area between the weighing hopper and the switching plate.

[0022] Secondly, the sulfur product weighing device of this utility model has an overlapping ring at the bottom of the weighing hopper that is adapted to the frustum tube at the bottom of the weighing hopper. This facilitates the sealing of the bottom of the weighing hopper by the switching sealing plate, ensuring the accuracy of weighing the sulfur inside the weighing hopper by multiple weighers between the overlapping ring and the fixed ring frame. This prevents the sulfur weighing operation from being affected by the requirement that the bottom end face of the weighing hopper must be in contact with the top surface of the switching sealing plate while maintaining a certain gap.

[0029] Example 1:

[0030] A weighing device for proportioning sulfur products, such as Figures 1-5 As shown, it includes a weighing hopper 1, a fixed ring frame 15 set at the bottom of the overlapping ring 3, multiple weighing devices 6, and a switching sealing plate 5 rotatably connected to one side of the bottom of the weighing hopper 1. The overlapping ring 3 is machined on the outer wall of the middle part of the weighing hopper 1. A rotary actuator 7 is assembled and connected at the center of the switching sealing plate 5. A frustum sleeve 9 is coaxially set at the bottom of the weighing hopper 1. A C-shaped groove 11 is machined inside the frustum sleeve 9. An ear piece 8 is welded to the outer wall of the frustum sleeve 9.

[0031] By assembling the rotary actuator 7 to the bottom of the ear plate 8, when the rotary actuator 7 is working, it can drive the switching sealing plate 5 located on the top of the ear plate 8 to rotate inside the C-shaped groove 11, so that the sulfur is controlled to fall from the bottom of the weighing hopper 1 around the switching sealing plate 5 (which can meet the feeding requirements of sulfur at different stages, and can also meet the intermittent feeding requirements at the same stage, which is conducive to adapting to the proportioning requirements of most products involving sulfur).

[0032] Secondly, by supporting the weighing device 6 between the overlapping ring 3 and the fixed ring frame 15, when sulfur is filled into the weighing hopper 1, the amount of sulfur to be added can be obtained by weighing with multiple weighing devices 6 (based on existing weighing sensor weighing technology).

[0033] Meanwhile, to facilitate the assembly of the weighing device 6 onto the top of the fixed ring frame 15, so that the weighing device 6 weighs the sulfur inside the hopper 1 symmetrically at the bottom of the overlapping ring 3, such as... Figure 3 and Figure 5 As shown, the top of the fixed ring frame 15 is machined with multiple circular grooves 12. By assembling multiple weighing devices 6 into the interior of the multiple circular grooves 12 respectively, and making their tops protrude from the top surface of the fixed ring frame 15, it can be ensured that the weighing devices 6 perform weighing work between the overlapping circular ring 3 and the fixed ring frame 15.

[0034] Furthermore, to ensure that the weighing hopper 1 moves vertically up and down, such as... Figure 1 and Figure 3 As shown, the bottom of the fixed ring frame 15 is assembled with a support platform 4, and the top of the fixed ring frame 15 is integrally formed with multiple guide rods 2. When the weighing hopper 1 is movably connected to the outside of the multiple guide rods 2 through the overlapping ring 3, the movement path can be controlled inside the overlapping ring 3 by means of the guide rods 2, so that the weighing hopper 1 and the fixed ring frame 15 can be kept in a coaxial state.

[0035] Furthermore, to facilitate suspending the frustum sleeve 9 at the bottom of the erection platform 4, such as... Figure 2 As shown, tube seats 10 are welded to the top outer walls on both sides of the frustum sleeve 9, and two fixed seats with round holes are welded to the bottom of both sides of the platform 4. When the frustum sleeve 9 is fixed to the bottom of the weighing hopper 1 by passing the round groove 12 through the two coaxial fixed seats and the tube seat 10, it can be ensured that the two tube seats 10 are symmetrically arranged on both sides of the C-shaped groove 11, so that the frustum sleeve 9 is coaxially fitted to the bottom of the weighing hopper 1.

[0036] This utility model discloses a weighing device for sulfur product proportioning. By machining an overlapping ring 3 on the outer wall of the weighing hopper 1, multiple weighing devices 6 are set between the fixed ring frame 15 assembled on the top of the support platform 4 and the overlapping ring 3. When a certain amount of sulfur is put into the weighing hopper 1 based on the sulfur hopper in the prior art (CN208135899U), the weighing of sulfur can be completed by the multiple weighing devices 6. When the rotary actuator 7 controls the switching plate 5 to rotate, so that the edge of the switching plate 5 is separated from the bottom of the weighing hopper 1, the sulfur can be completely released to the bottom, and the problem of sulfur residue in the connection area between the weighing hopper 1 and the switching plate 5 can be avoided as much as possible.

[0037] Example 2:

[0038] Based on Example 1, such as Figure 1 , Figure 3 and Figure 5 As shown in the figure, this embodiment is the specific structure of the weighing hopper 1 of the weighing device for the proportioning of sulfur products. An adjusting ring 13 is slidably connected to the inner side of the bottom of the weighing hopper 1, and the bottom cross section of the weighing hopper 1 is an isosceles trapezoid.

[0039] In this process, by adapting and connecting the adjusting ring 13 to the inside of the weighing hopper 1, and when the bottom end face of the adjusting ring 13 is flush with the bottom end face of the weighing hopper 1, a complete frustum tube is formed. When the adjusting ring 13 hangs down naturally inside the weighing hopper 1, the sulfur in the weighing hopper 1 can fall down along the inner wall to the bottom without any protrusions or obstructions.

[0040] Meanwhile, when the bottom end face of the adjusting ring 13 is in contact with the top surface of the switching sealing plate 5, and sulfur is filled inside the weighing hopper 1 and weighed by multiple weighing devices 6, and the weighing hopper 1 maintains a slight downward movement trend, the weighing hopper 1 can move downward outside the adjusting ring 13, and the bottom end face of the weighing hopper 1 will not directly contact the top surface of the switching sealing plate 5, thus affecting the accuracy of the multiple weighing devices 6 weighing the sulfur inside the weighing hopper 1 between the overlapping ring 3 and the fixed ring frame 15.

[0041] Secondly, to prevent the adjusting ring 13 from detaching from the inside of the weighing hopper 1 towards the bottom, such as Figure 5 As shown. Both sides of the bottom of the weighing hopper 1 are machined with strip grooves 16. Each of the two strip grooves 16 is provided with a screw 14. One end of the screw 14 is threadedly connected to the inside of the adjusting ring 13. By means of the movable path of the screw 14 inside the strip groove 16, the adjusting ring 13 connected to the screw 14 can be prevented from detaching from the inside of the weighing hopper 1.

[0042] This utility model discloses a weighing device for sulfur product proportioning. By setting an overlapping ring 3 at the bottom of the weighing hopper 1, which is adapted to the frustum tube at the bottom of the weighing hopper 1, the movement range of the adjusting ring 13 inside the weighing hopper 1 can be controlled when the screw 14 connected to the inside of the adjusting ring 13 slides inside the strip groove 16. This facilitates the switching of the sealing plate 5 to seal the bottom of the weighing hopper 1, ensuring the accuracy of weighing the sulfur inside the weighing hopper 1 by multiple weighers 6 between the overlapping ring 3 and the fixed ring frame 15. This is not affected by the fact that the bottom end face of the weighing hopper 1 needs to be in contact with the top surface of the switching sealing plate 5, while also maintaining a certain gap (to accommodate the pressure deformation of the pressure sensing element inside the weigher 6).

[0043] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
