Description

Technical Field

[0001] The present application relates to the technical field of chemical equipment, and in particular to a rapid sulfur melting tank. Background Art

[0002] In the sulfur-based acid production process, solid sulfur needs to be heated and melted to form liquid sulfur to be used as a raw material for acid production. Usually, a sulfur melting tank is used to heat melt the solid sulfur.

[0003] The existing sulfur melting tank includes a tank body and a heat coil. The heat coil is arranged in the tank body. Solid sulfur is placed between the heat coil and the inner wall of the tank body. Water vapor is introduced into the heat coil. The water vapor transfers heat to the solid sulfur through the heat coil to heat the solid sulfur, so that the solid sulfur is heated and converted into liquid to obtain liquid sulfur raw material for acid production.

[0004] Solid sulfur has poor fluidity in the tank, and the heat coil can only fully heat the solid sulfur around itself. Even with an auxiliary stirring device, some of the solid sulfur in the tank will still be difficult to melt, which can easily lead to material accumulation in the tank. Summary of the invention

[0005] In order to enable solid sulfur to be fully melted and not easily accumulated in the tank body, the present application provides a rapid sulfur melting tank.

[0006] The present application provides a rapid sulfur melting tank, which adopts the following technical solution: A fast sulfur melting tank, comprising: The tank body has an opening at the top, a top cover is arranged at the opening of the tank body, and the bottom end of the tank body is connected to a sulfur discharge pipe; A steam pipe is arranged in the tank body and penetrates the top cover, and is used to pass water vapor into the steam pipe; A first heating filter plate is slidably arranged in the tank body and sleeved on the steam pipe; The second heating filter plate is arranged in the tank body and located at the bottom end of the steam pipe; A multi-stage telescopic tube is arranged between the first heating filter plate and the second heating filter plate. A lifting spring is arranged in the multi-stage telescopic tube. The lifting spring is used to drive the multi-stage telescopic tube to push the first heating filter plate to slide away from the second heating filter plate. Among them, the plate bodies of the first heating filter plate and the second heating filter plate are both hollow inside, and a connecting component is arranged between the first heating filter plate and the steam pipe. The connecting component is used to ensure that the first heating filter plate can always be connected with the steam pipe during the sliding process, and the second heating filter plate is connected with the bottom end of the steam pipe.

[0007] By adopting the above technical scheme, when melting solid sulfur, solid sulfur is added into the tank body, and the solid sulfur pushes the first heating filter plate down by gravity, so that space for storing solid sulfur is left in the tank body to improve the utilization rate of the internal space of the tank body, and water vapor is passed into the steam pipe. The water vapor in the steam pipe flows into the first heating filter plate through the connecting component, and directly flows into the second heating filter plate. The first heating filter plate heats the solid sulfur in contact with itself, so that the solid sulfur is heated and melted into liquid sulfur. The liquid sulfur flows to the second heating filter plate after primary filtration by the first heating filter plate. The second heating filter plate heats the liquid sulfur to keep the liquid sulfur in a liquid state. The liquid sulfur flows to the sulfur discharge pipe after secondary filtration by the second heating filter plate, and is discharged from the tank body from the sulfur discharge pipe. Since the first heating filter plate can directly contact each part of the solid sulfur, and each liquefied part of the solid sulfur can be directly filtered and discharged, all the solid sulfur put into the tank body will be liquefied after contacting the first heating filter plate, so that all the solid sulfur in the tank body can be fully melted and not easy to accumulate in the tank body.

[0008] Optionally, the connecting component includes a telescopic air pipe, a slide plate and a connecting spring; A plurality of telescopic air pipes are arranged along the circumference of the steam pipe, and the fixed end of each telescopic air pipe is slidably arranged in a sliding hole opened on the side wall of the steam pipe; There are multiple slide plates, which correspond to the telescopic air pipes one by one. The slide plates are slidably arranged on the inner wall of the steam pipe. The slide plates are located at the slide holes and always close the slide holes. The fixed ends of the telescopic air pipes are passed through the slide plates. There are multiple groups of connecting springs, which correspond to the telescopic air pipes one by one. Each group of connecting springs has at least one connecting spring. The connecting spring is located in the telescopic air pipe and connected between the movable end and the fixed end of the telescopic air pipe. The connecting spring is used to drive the movable end of the telescopic air pipe to be sealed and inserted into the connecting hole opened on the first heating filter plate. The telescopic air pipe is connected with the steam pipe and the first heating filter plate.

[0009] By adopting the above technical solution, when installing the first heating filter plate, the movable end of the telescopic air pipe is first placed in a contracted state, and then the connecting hole on the first heating filter plate is placed opposite to the telescopic air pipe. The movable end of the telescopic air pipe is inserted into the connecting hole under the drive of the connecting spring, so that the first heating filter plate can be connected with the inside of the steam pipe through the telescopic air pipe, and because the telescopic air pipe is connected to the slide plate, the first heating filter plate can always be in a connected state with the inside of the steam pipe during the sliding process; because the slide plate can always close the sliding hole, it is difficult for liquid sulfur to enter the steam pipe.

[0010] Optionally, a pull rope is connected to the movable end of each telescopic air pipe, and the pull ropes are arranged in the telescopic air pipe and the steam pipe. The ends of all the pull ropes away from the movable ends of the telescopic air pipes are commonly connected to a pull ring, and the pull ring is hung on a hook arranged on the inner wall of the steam pipe near the top.

[0011] By adopting the above technical solution, the pull rope can slide in the telescopic air pipe and the steam pipe by pulling the pull ring, and the pull rope can pull the telescopic air pipe to contract, so that the movable end of the telescopic air pipe can be easily inserted into the connecting hole.

[0012] Optionally, a flip assembly is provided on the side of the first heating filter plate away from the second heating filter plate, and the flip assembly includes a flip plate and a slider. One side of the flip plate abuts against the first heating filter plate, and the flip plate is inclined relative to the first heating filter plate. The slider is connected to the flip plate and is slidably arranged in a spiral groove opened on the inner wall of the trough body.

[0013] By adopting the above technical scheme, when the first heating filter plate slides up, the first heating filter plate pushes the flip plate to move up, and under the spiral guiding action of the spiral slide groove on the slider, the flip plate can spirally rotate around the steam pipe, and the inclined flip plate can shovel the solid sulfur close to the first heating filter plate, so that the solid sulfur can be flipped, so that the solid sulfur and the first heating filter plate are easily and evenly contacted, and the flip plate can clean the blockage at the filter hole of the first heating filter plate when the spiral rotates, so that the first heating filter plate is not easy to be blocked.

[0014] Optionally, the first heating filter plate is connected to a first vibration assembly, the first vibration assembly comprising a vibration ridge, a rotating ring and a guide plate; A plurality of vibrating ridges are arranged along the circumference of the steam pipe, and are all connected to a side of the first heating filter plate close to the second heating filter plate; The rotating ring is adapted to be arranged in a vibration ring hole opened on a side of the second heating filter plate close to the first heating filter plate, and is rotatably connected to the steam pipe and the second heating filter plate; A plurality of guide plates are arranged around the rotation axis of the rotating ring and are all located inside the second heating filter plate. The guide plates are connected to the rotating ring and are arranged tilted relative to the diameter direction of the rotating ring. The multi-stage telescopic tube is connected to the rotating ring, and the plurality of vibrating ridges are all located on a moving path of the multi-stage telescopic tube as the rotating ring rotates.

[0015] By adopting the above technical solution, the water vapor in the steam pipe flows into the second heating filter plate, and the water vapor is blown onto the multiple guide plates in the second heating filter plate in the form of airflow. The water vapor flow drives the guide plate to rotate, and the guide plate drives the rotating ring to rotate, and the rotating ring drives the multi-stage telescopic tube to rotate, so that the movable end of the smallest stage of the multi-stage telescopic tube can slide over the multiple vibrating ridges one by one, and each time the multi-stage telescopic tube slides over a vibrating ridge, it can knock on the first heating filter plate under the elastic force of the lifting spring, thereby making the first heating filter plate less prone to clogging; when the multi-stage telescopic tube rotates, it can stir the liquid sulfur between the first heating filter plate and the second heating filter plate, so that the contact between the liquid sulfur and the second heating filter plate is easy and uniform.

[0016] Optionally, the fixed end of the multi-stage telescopic tube is passed through the rotating ring and is connected to the second heating filter plate.

[0017] By adopting the above technical solution, the water vapor in the second heating filter plate can flow into the multi-stage telescopic tube, and the multi-stage telescopic tube can heat the liquid sulfur between the first heating filter plate and the second heating filter plate, so that the liquid sulfur can be easily kept in a liquid state.

[0018] Optionally, a stirring plate is connected to the fixed end of the multi-stage telescopic tube, and the stirring plate abuts against the second heating filter plate.

[0019] By adopting the above technical solution, the stirring plate can rotate with the multi-stage telescopic tube. When the stirring plate rotates, it can stir the liquid sulfur close to the second heating filter plate, so that the liquid sulfur is easy to contact and heat the second heating filter plate evenly; when the stirring plate rotates, it can clean the filter holes of the second heating filter plate, so that the second heating filter plate is not easy to be blocked.

[0020] Optionally, a second vibration assembly is provided in the second heating filter plate, and the second vibration assembly includes a guide bevel block, a knocking rod, a knocking ball and a lever, the guide bevel block is connected on a side of the second heating filter plate away from the first heating filter plate, one end of the knocking rod is slidably set on the inclined surface of the guide bevel block, the knocking ball is connected to the other end of the knocking rod, a plurality of levers are provided and correspond one-to-one to the guide plates, the levers are connected to the guide plates, and when the guide plates drive the rotating ring to rotate, the levers can drive the knocking rod to slide so that the knocking ball knocks on the second heating filter plate.

[0021] By adopting the above technical solution, when the water vapor flow drives the guide plate to rotate, the guide plate synchronously drives the lever to rotate. When the lever rotates to the position of the knocking rod, the lever can push the knocking rod to slide on the guide bevel block, so that the knocking rod gradually slides to the top of the inclined surface of the guide bevel block, so that the knocking rod can drive the knocking ball to knock on the second heating filter plate, making the second heating filter plate less likely to be blocked.

[0022] Optionally, a heat preservation chamber is opened inside the side wall of the trough body, the second heating filter plate is connected to the heat preservation chamber, and an exhaust pipe is connected to the bottom of the outer side wall of the trough body, and the exhaust pipe is connected to the heat preservation chamber.

[0023] By adopting the above technical solution, the water vapor in the second heating filter plate can flow into the heat preservation chamber from the connecting pipe, and the water vapor can increase the temperature in the heat preservation chamber, thereby reducing the temperature difference between the inside and outside of the tank body, thereby forming a heat preservation layer for the liquid sulfur in the tank body.

[0024] Optionally, a one-way air valve is provided in the steam pipe, the one-way air valve is always located between the first heating filter plate and the second heating filter plate, and the conducting direction of the one-way air valve is from the top end of the steam pipe toward the bottom end of the steam pipe.

[0025] By adopting the above technical solution, when the air pressure on the side of the one-way air valve close to the first heating filter plate is not greater than the conduction air pressure, the water vapor in the steam pipe will continue to flow into the first heating filter plate until the one-way air valve can be conducted, and then the water vapor will flow to the second heating filter plate, thereby increasing the filling speed of the water vapor in the first heating filter plate, thereby facilitating the rapid heating of the first heating filter plate to heat the solid sulfur.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-6 This application is described in further detail.

[0030] The present application embodiment discloses a rapid sulfur melting tank. Figure 1 and Figure 2 A rapid sulfur melting tank includes a tank body 1, a steam pipe 2, a first heating filter plate 3, a second heating filter plate 4 and a multi-stage telescopic pipe 5.

[0031] Reference Figure 2 The tank body 1 is in the shape of a vertically arranged circular tank, and the opening is located at the top of the tank body 1. A top cover 11 is provided at the opening of the tank body 1, and the top cover 11 is bolted to the tank body 1. By opening the top cover 11, solid sulfur can be added from the opening of the tank body 1. The bottom end of the tank body 1 is connected to a sulfur discharge pipe 12, and the sulfur discharge pipe 12 is used to discharge the melted liquid sulfur in the tank body 1.

[0032] The steam pipe 2 is in the shape of a circular tube, is coaxially arranged in the tank body 1, and is slidably penetrated on the top cover 11. The steam pipe 2 is used to pass water vapor, and the water vapor in the steam pipe 2 is a heat source for heating solid sulfur.

[0033] The first heating filter plate 3 is slidably arranged in the tank body 1 along the vertical direction. The first heating filter plate 3 is in the shape of a circular ring plate and is sleeved on the steam pipe 2. The first heating filter plate 3 is hollow inside. A connecting component 6 is arranged between the first heating filter plate 3 and the steam pipe 2. The connecting component 6 is used to ensure that the first heating filter plate 3 is always in a connected state with the steam pipe 2 during the sliding process. The first heating filter plate 3 can heat solid sulfur and perform primary filtration on impurities contained in liquid sulfur.

[0034] The second heating filter plate 4 is fixed in the tank body 1 and is located at the bottom end of the steam pipe 2. The second heating filter plate 4 is hollow inside and is connected to the bottom end of the steam pipe 2. The filtering accuracy of the second heating filter plate 4 is higher than that of the first heating filter plate 3. The second heating filter plate 4 can heat the liquid sulfur to keep the liquid sulfur in a liquid state, and the second heating filter plate 4 can perform secondary filtration on impurities in the liquid sulfur.

[0035] Reference Figure 2 and Figure 3 , three multi-stage telescopic tubes 5 are vertically arranged, and all are located between the first heating filter plate 3 and the second heating filter plate 4. The three multi-stage telescopic tubes 5 are evenly arranged around the steam pipe 2. A lifting spring 51 is arranged in each multi-stage telescopic tube 5. One end of the lifting spring 51 is fixedly connected to the fixed end of the multi-stage telescopic tube 5, and the other end is fixedly connected to the movable end of the smallest stage of the multi-stage telescopic tube 5. The lifting spring 51 is used to drive the multi-stage telescopic tube 5 to push the first heating filter plate 3 to slide away from the second heating filter plate 4. When the solid sulfur gradually liquefies and reduces the gravity effect on the first heating filter plate 3, the lifting spring 51 can drive the first heating filter plate 3 to slide away from the second heating filter plate 4, so that the first heating filter plate 3 slides up.

[0036] When melting solid sulfur, solid sulfur is added into the tank body 1. The solid sulfur pushes the first heating filter plate 3 downward by gravity, leaving space for storing solid sulfur in the tank body 1 to improve the utilization rate of the internal space of the tank body 1. Water vapor is passed into the steam pipe 2. The water vapor in the steam pipe 2 flows into the first heating filter plate 3 through the connecting component 6, and directly flows into the second heating filter plate 4. The first heating filter plate 3 heats the solid sulfur in contact with itself, so that the solid sulfur is heated and melted into liquid sulfur. The liquid sulfur flows to the second heating filter plate 4 after being filtered by the first heating filter plate 3. On the heating filter plate 4, the second heating filter plate 4 heats the liquid sulfur to keep the liquid sulfur in a liquid state. After the second-level filtration of the second heating filter plate 4, the liquid sulfur flows to the sulfur discharge pipe 12 and is discharged from the tank body 1 from the sulfur discharge pipe 12. Since the first heating filter plate 3 can directly contact each part of the solid sulfur, and each liquefied part of the solid sulfur can be directly filtered and discharged, all the solid sulfur put into the tank body 1 will be liquefied after contacting the first heating filter plate 3, so that all the solid sulfur in the tank body 1 can be fully melted and not easily accumulated in the tank body 1.

[0037] Specifically, refer to Figure 4 The connecting component 6 includes a telescopic air pipe 61, a slide plate 62 and a connecting spring 63.

[0038] Reference Figure 2 and Figure 4Three telescopic air pipes 61 are arranged along the circumference of the steam pipe 2. The fixed end of each telescopic air pipe 61 is slidably arranged in the sliding hole 21 opened on the side wall of the steam pipe 2. The sliding direction of the telescopic air pipe 61 is consistent with the sliding direction of the first heating filter plate 3. Three slide plates 62 are arranged, and they correspond to the telescopic air pipes 61 one by one. The slide plates 62 are bent into an arc shape that matches the inner wall of the steam pipe 2, and are slidably arranged on the inner wall of the steam pipe 2. The slide plates 62 are located at the sliding hole 21 and always close the sliding hole 21. The fixed end of the telescopic air pipe 61 is fixedly penetrated on the slide plates 62. The slide plates 62 isolate the interior of the steam pipe 2 from the interior of the tank body 1.

[0039] Reference Figure 4 There are three groups of connecting springs 63, which correspond to the telescopic air pipes 61 one by one. There are four connecting springs 63 in each group. The four connecting springs 63 are all located in the telescopic air pipe 61 and are evenly arranged around the axis of the telescopic air pipe 61. The connecting springs 63 are fixed between the movable end and the fixed end of the telescopic air pipe 61. The connecting springs 63 are used to drive the movable end of the telescopic air pipe 61 to be sealed and inserted into the connecting hole 31 opened on the first heating filter plate 3. The telescopic air pipe 61 connects the steam pipe 2 and the first heating filter plate 3.

[0040] When installing the first heating filter plate 3, first put the movable end of the telescopic air pipe 61 in a contracted state, then make the connecting hole 31 on the first heating filter plate 3 face the telescopic air pipe 61, and the movable end of the telescopic air pipe 61 is inserted into the connecting hole 31 under the drive of the connecting spring 63, so that the first heating filter plate 3 can be connected with the inside of the steam pipe 2 through the telescopic air pipe 61, and because the telescopic air pipe 61 is connected to the slide plate 62, the first heating filter plate 3 can always be in a connected state with the inside of the steam pipe 2 during the sliding process; because the slide plate 62 can always close the sliding hole 21, it is difficult for liquid sulfur to enter the steam pipe 2.

[0041] Further, refer to Figure 3 and Figure 4 A pull rope 64 is connected to the movable end of each telescopic air pipe 61. The pull rope 64 is arranged in the telescopic air pipe 61 and the steam pipe 2 and can slide relative to the telescopic air pipe 61 and the steam pipe 2. A pull ring 65 is commonly fixedly connected to one end of all the pull ropes 64 away from the movable end of the telescopic air pipe 61. The pull ring 65 is hung on a hook 22 fixed on the inner wall of the steam pipe 2 near the top.

[0042] By pulling the pull ring 65 , the pull rope 64 can slide in the telescopic air pipe 61 and the steam pipe 2 , and the pull rope 64 can pull the telescopic air pipe 61 to contract, so that the movable end of the telescopic air pipe 61 can be easily inserted into the connecting hole 31 .

[0043] Furthermore, refer to Figure 3 and Figure 4In order to make it difficult for liquid sulfur to flow directly between the first heating filter plate 3 and the steam pipe 2, a support plate 621 is fixedly connected to the three slide plates 62. The first heating filter plate 3 abuts against the support plate 621. The support plate 621 closes the space between the first heating filter plate 3 and the steam pipe 2, making it difficult for liquid sulfur to flow directly between the first heating filter plate 3 and the steam pipe 2. At the same time, the support plate 621 positions the first heating filter plate 3, making it convenient for the movable end of the telescopic air pipe 61 to be inserted into the connecting hole 31.

[0044] Reference Figure 2 In order to make the solid sulfur contact with the first heating filter plate 3 evenly, a flip assembly 7 is provided on the side of the first heating filter plate 3 away from the second heating filter plate 4. The flip assembly 7 includes a flip plate 71 and a slider 72. One side of the flip plate 71 abuts against the first heating filter plate 3, and the flip plate 71 is inclined relative to the first heating filter plate 3; the slider 72 is fixedly connected to one end of the flip plate 71. The slider 72 is in a rectangular block shape and is slidably arranged in a spiral groove 13 opened on the inner side wall of the trough body 1. The spiral groove 13 can guide the slider 72 to spirally rise, and under the restriction of the spiral groove 13, the slider 72 is difficult to rotate relative to the trough body 1.

[0045] When the first heating filter plate 3 slides up, the first heating filter plate 3 pushes the flip plate 71 to move upward, and under the spiral guiding action of the spiral slide groove 13 on the slider 72, the flip plate 71 can spirally rotate around the steam pipe 2, and the inclined flip plate 71 can shovel the solid sulfur close to the first heating filter plate 3, so that the solid sulfur can be flipped, so that the solid sulfur and the first heating filter plate 3 are easily and evenly contacted, and the flip plate 71 can clean the blockage at the filter hole of the first heating filter plate 3 when spirally rotating, so that the first heating filter plate 3 is not easily blocked.

[0046] Reference Figure 3 In order to allow the first heating filter plate 3 to preferentially enter water vapor to accelerate the melting of solid sulfur, a one-way air valve 23 is provided in the steam pipe 2. The one-way air valve 23 is always located between the first heating filter plate 3 and the second heating filter plate 4. The conduction direction of the one-way air valve 23 is from the top end of the steam pipe 2 toward the bottom end of the steam pipe 2.

[0047] When the air pressure on the side of the one-way air valve 23 close to the first heating filter plate 3 is not greater than the conduction air pressure, the water vapor in the steam pipe 2 will continue to flow into the first heating filter plate 3 until the one-way air valve 23 can be conducted, and then the water vapor will flow to the second heating filter plate 4, thereby increasing the filling speed of the first heating filter plate 3 with water vapor, thereby facilitating the first heating filter plate 3 to quickly heat up to heat the solid sulfur.

[0048] Reference Figure 2In order to prevent the heat in the tank body 1 from diffusing easily to the outside of the tank body 1 through the side wall of the tank body 1, a heat preservation chamber 14 is opened inside the side wall of the tank body 1, and a connecting pipe 42 is connected between the second heating filter plate 4 and the heat preservation chamber 14. The connecting pipe 42 connects the second heating filter plate 4 and the heat preservation chamber 14, so that the water vapor in the second heating filter plate 4 can flow into the heat preservation chamber 14. An exhaust pipe 15 is fixedly provided at the bottom of the outer side wall of the tank body 1, and the exhaust pipe 15 is connected to the heat preservation chamber 14, so that the water vapor and condensed water in the heat preservation chamber 14 can be discharged.

[0049] The water vapor in the second heating filter plate 4 can flow into the heat preservation chamber 14 from the connecting pipe 42 , and the water vapor can increase the temperature in the heat preservation chamber 14 , thereby reducing the temperature difference between the inside and outside of the tank body 1 , thereby forming a heat preservation layer for the liquid sulfur in the tank body 1 .

[0050] Reference Figure 3 In order to further prevent the first heating filter plate 3 from being blocked, a first vibration assembly 8 is connected to the first heating filter plate 3 . The first vibration assembly 8 includes a vibration ridge 81 , a rotating ring 82 and a guide plate 83 .

[0051] A plurality of vibration ridges 81 are arranged along the circumference of the steam pipe 2, and are all fixedly connected to the side of the first heating filter plate 3 close to the second heating filter plate 4, and the vibration ridges 81 are in the shape of a semicircular column. The rotating ring 82 is in the shape of a circular ring, and is adapted to be arranged in the vibration ring hole 41 opened on the side of the second heating filter plate 4 close to the first heating filter plate 3, and the rotating ring 82 is rotatably connected to the second heating filter plate 4 around the steam pipe 2.

[0052] Reference Figure 3 and Figure 5 , multiple guide plates 83 are arranged around the rotation axis of the rotating ring 82, and all are located in the second heating filter plate 4. The guide plates 83 are fixedly connected to the rotating ring 82, and the guide plates 83 are arranged obliquely relative to the diameter direction of the rotating ring 82. The water vapor flow in the second heating filter plate 4 blows on the guide plates 83 to drive the rotating ring 82 to rotate. Three multi-stage telescopic tubes 5 are all connected to the rotating ring 82, and the movable end of the smallest stage of the multi-stage telescopic tube 5 is in a hemispherical sealing shape. Multiple vibration ridges 81 are all located on the moving path of the multi-stage telescopic tube 5 rotating with the rotating ring 82. The hemispherical sealing end of the multi-stage telescopic tube 5 is easy to slide over the semicircular columnar vibration ridge 81.

[0053] The water vapor in the steam pipe 2 flows into the second heating filter plate 4, and the water vapor is blown onto the multiple guide plates 83 in the form of airflow in the second heating filter plate 4. The water vapor flow pushes the guide plate 83 to rotate, and the guide plate 83 drives the rotating ring 82 to rotate, and the rotating ring 82 drives the multi-stage telescopic tube 5 to rotate, so that the movable end of the smallest stage of the multi-stage telescopic tube 5 can slide over the multiple vibrating ridges 81 one by one, and each time the multi-stage telescopic tube 5 slides over a vibrating ridge 81, it can knock on the first heating filter plate 3 under the elastic force of the lifting spring 51, so that the first heating filter plate 3 is further less likely to be blocked; when the multi-stage telescopic tube 5 rotates, it can stir the liquid sulfur between the first heating filter plate 3 and the second heating filter plate 4, so that the contact between the liquid sulfur and the second heating filter plate 4 is easy and uniform.

[0054] Further, refer to Figure 3 The fixed end of the multi-stage telescopic tube 5 is fixedly installed on the rotating ring 82 and is connected with the second heating filter plate 4, so that the water vapor in the second heating filter plate 4 can flow into the multi-stage telescopic tube 5, and the multi-stage telescopic tube 5 can heat the liquid sulfur between the first heating filter plate 3 and the second heating filter plate 4, so that the liquid sulfur can be easily maintained in a liquid state.

[0055] Furthermore, refer to Figure 2 In order to improve the contact uniformity between the liquid sulfur near the second heating filter plate 4 and the second heating filter plate 4 , two stirring plates 52 are fixedly connected to the fixed end of the multi-stage telescopic tube 5 , and the stirring plates 52 are in contact with the second heating filter plate 4 .

[0056] The stirring plate 52 can rotate with the multi-stage telescopic tube 5. When rotating, the stirring plate 52 can stir the liquid sulfur close to the second heating filter plate 4, so that the liquid sulfur is easy to contact and heat with the second heating filter plate 4 evenly; when rotating, the stirring plate 52 can clean the filter holes of the second heating filter plate 4, so that the second heating filter plate 4 is not easy to be blocked.

[0057] Reference Figure 3 and Figure 6 In order to further prevent the second heating filter plate 4 from being blocked, three groups of second vibration components 9 are arranged in the second heating filter plate 4. The three groups of second vibration components 9 are evenly arranged around the steam pipe 2. The second vibration component 9 includes a guide bevel 91, a knocking rod 92, a knocking ball 93 and a lever 94.

[0058] The guide bevel block 91 is fixedly connected to the side of the second heating filter plate 4 away from the first heating filter plate 3, and the guide bevel block 91 is located outside the rotation area of ​​the guide plate 83. The knocking rod 92 is vertically arranged, and the bottom end is slidably arranged on the inclined surface of the guide bevel block 91. The knocking ball 93 is fixedly connected to the top of the knocking rod 92, and the knocking rod 92 can drive the knocking ball 93 to slide, and when the knocking rod 92 slides to the top of the inclined surface of the guide bevel block 91, the knocking ball 93 can knock on the second heating filter plate 4.

[0059] There are multiple levers 94, which correspond to the guide plates 83 one by one. The levers 94 are fixedly connected to one end of the guide plate 83 away from the steam pipe 2. When the guide plate 83 drives the rotating ring 82 to rotate, the levers 94 can drive the knocking rod 92 to slide, so that the knocking ball 93 knocks on the second heating filter plate 4.

[0060] When the water vapor flow drives the guide plate 83 to rotate, the guide plate 83 synchronously drives the lever 94 to rotate. When the lever 94 rotates to the position of the knocking rod 92, the lever 94 can push the knocking rod 92 to slide on the guide bevel block 91, so that the knocking rod 92 gradually slides to the top of the inclined surface of the guide bevel block 91, so that the knocking rod 92 can drive the knocking ball 93 to knock on the second heating filter plate 4, making the second heating filter plate 4 less likely to be blocked.

[0061] The implementation principle of a fast sulfur melting tank in an embodiment of the present application is as follows: when in use, solid sulfur is added into the tank body 1, and the solid sulfur pushes the first heating filter plate 3 down by gravity to leave space for adding solid sulfur, and water vapor is passed into the steam pipe 2, and the water vapor first passes into the first heating filter plate 3, and then into the second heating filter plate 4, and then flows into the heat preservation chamber 14, and finally is discharged from the exhaust pipe 15, the first heating filter plate 3 heats and filters the solid sulfur, the second heating filter plate 4 heats and filters the liquid sulfur, and the first heating filter plate 3 gradually melts the solid sulfur, so that each part of the solid sulfur can be heated and melted, so that the solid sulfur can be fully melted and is not easy to accumulate in the tank body 1.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
