Description

Technical Field

[0001] The present disclosure relates to the technical field of sulfuric acid production equipment, and in particular to an extraction and standing mechanism and a sulfur slag recovery device. Background Art

[0002] In the sulfuric acid production process, the purification of sulfur is an important step. Sulfur filtration will produce sulfur slag, the main components of which are 30%-40% inorganic salts and ash, and 60%-70% sulfur. The main components of inorganic salts are sodium sulfate and calcium sulfate, and the ash is impurities such as silicon dioxide. A large amount of sulfur slag accumulation will lead to the blockage of roads and rivers, causing environmental pollution. In addition, sulfur slag is easy to burn when it comes into contact with fire, causing safety hazards.

[0003] Existing sulfur slag separation equipment such as CN 110772833 A discloses a spiral high-efficiency sulfur extraction device, which includes an extraction tank, a first feed port, a second feed port, a dissolving tank, and a drain port. The extraction tank is a closed cavity structure, and the dissolving tank is spirally arranged around the axis of the extraction tank and evenly distributed from top to bottom along the axis of the extraction tank. The upper end surface of the dissolving tank is connected to the first feed port and the second feed port, and the lower end surface is connected to the drain port. The extractant and crude sulfur are first added to the dissolving tank in the extraction tank from the first feed port and the second feed port respectively, and flow from top to bottom along the axis of the extraction tank. During the flow process, the extractant and the crude sulfur are mixed and extracted, and then the mixed liquid flows into the extraction tank, and solid-liquid separation operation is performed through a filter screen. The separated liquid material is discharged through the drain port at the bottom of the extraction tank to complete the extraction operation.

[0004] However, the above-mentioned sulfur slag separation equipment needs to add a filter screen for solid-liquid separation. After a certain period of extraction, the filter screen is easily blocked by sulfur slag solids and needs to be disassembled and cleaned, which is less convenient to use. Since the above-mentioned sulfur slag separation equipment needs to extract first and then filter, the extraction efficiency of the sulfur slag separation equipment is low. Utility Model Content

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0045] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0046] like Figures 1 to 5 As shown, an extraction stationary mechanism 10 of an embodiment includes an extraction cylinder 100, a driving assembly 200, a spiral blade 300, a sulfur slurry inlet pipe 400 and an extractant inlet pipe 500. The extraction cylinder 100 is arranged at an inclination relative to a horizontal plane. The extraction cylinder 100 is provided with an extraction chamber 101, an extraction phase outlet 102, a mounting hole 103 and a solid outlet 104. The extraction chamber 101 is connected to the extraction phase outlet 102, the mounting hole 103 and the solid outlet 104 respectively. The extraction phase outlet 102 is arranged near the top of the extraction cylinder 100, and the solid outlet 104 is located above the extraction phase outlet 102. Figures 3 to 5 As shown, in this embodiment, the extraction phase outlet 102 , the solid outlet 104 and the mounting hole 103 are sequentially opened along the axial extension direction of the extraction tube 100 .

[0047] In one embodiment, the driving assembly 200 includes a rotating driving member 210 and a rotating shaft 220, the rotating shaft 220 is rotatably arranged in the mounting hole 103, the rotating driving member 210 is located outside the extraction cylinder 100, and the driving end of the rotating driving member 210 is fixedly connected to the rotating shaft 220. In this embodiment, the rotating driving member 210 is fixed to the outside of the extraction cylinder 100 by a fixing bracket (not shown). Further, the rotating driving member 210 is a motor or a rotating electric cylinder.

[0048] In one embodiment, the spiral blade 300 is located in the extraction chamber 101, and the spiral blade 300 is spirally arranged on the outer side of the rotating shaft 220, and one end of the spiral blade 300 extends at least to a position corresponding to the solid outlet 104, so that impurities are transmitted upward and flow out from the solid outlet 104 when the spiral blade 300 rotates; the spiral blade 300 is provided with a filtering area, so that part of the extraction mixed liquid is retained in the extraction chamber 101 through the filtering area; the sulfur slurry inlet pipe 400 is connected to the extraction chamber 101; the extractant inlet pipe 500 is connected to the extraction chamber 101.

[0049] In this embodiment, sulfur slurry enters the extraction chamber 101 through the sulfur slurry inlet pipe 400, and the extractant enters the extraction chamber 101 through the extractant inlet pipe 500. The sulfur slurry is mixed in the extractant, and the rotating shaft 220 is driven to rotate by the rotating driving member 210, so that the rotating shaft 220 drives the rotation of the spiral blade 300. The extraction mixed liquid is transmitted upward with the rotation of the spiral blade 300, so that the extraction mixed liquid flows out from the extraction phase outlet 102, and part of the extraction mixed liquid is retained in the extraction chamber 101 through the filtering area, reducing the possibility of the extraction mixed liquid flowing out from the solid outlet 104, and the impurities brought by the sulfur slurry, such as silicon dioxide, are transmitted through the spiral blade 300. Since one end of the spiral blade 300 at least extends to the position corresponding to the solid outlet 104, and the extraction cylinder 100 is inclined relative to the horizontal plane, the impurities are guided by the spiral blade 300 and the impurities themselves Under the gravity of the gravity, the impurities finally flow out through the solid outlet 104, which is convenient for subsequent processing, and the extraction static mechanism 10 can realize extraction and filtration at the same time, without the need to set up an additional filter, and the extraction efficiency is high. Furthermore, the extractant is vinyl chloride or carbon disulfide.

[0050] It can be understood that the sulfur slurry is formed by mixing sulfur slag with water, the sulfur slag includes impurities such as inorganic salts and sulfur, and the extraction and static mechanism 10 extracts the sulfur slurry and the extract. The extraction process of the sulfur slurry and the extract is a known technology, and the present disclosure only protects the positional relationship and connection relationship of the components in the extraction and static mechanism 10.

[0051] Furthermore, there are multiple extraction phase outlets 102 , and the multiple extraction phase outlets 102 are arranged around the peripheral wall of the extraction cylinder 100 , so that the extraction mixed liquid flows into the phase separation cylinder 600 more quickly.

[0052] Furthermore, the filtering area is a plurality of return holes 301 , and the plurality of return holes 301 are arranged at intervals along the spiral direction of the spiral blade 300 .

[0053] Of course, in other embodiments, the filtration area is not limited to a plurality of fall-back holes 301. For example, Figure 6As shown, the filtering area is a return groove 302, that is, the spiral blade 300 is provided with a plurality of return grooves 302, and the plurality of return grooves 302 are arranged side by side along the width direction of the spiral blade 300. In this embodiment, the number of the return grooves 302 is two.

[0054] like Figure 5 As shown, in one embodiment, a stirring rod 110 is further provided in the extraction cylinder 100, the axial direction of the stirring rod 110 is parallel to the axial direction of the rotating shaft 220, and is connected to the spiral blade 300. It can be understood that when the spiral blade 300 rotates, the stirring rod 110 can stir the sulfur slurry and the extractant, accelerate the mixing rate between the sulfur slurry and the extractant, improve the extraction efficiency, and have a better extraction effect.

[0055] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the extraction static mechanism 10 also includes a phase-separation cylinder 600, which is provided with a connected phase-separation cavity 601 and a fixing hole 602, and the extraction cylinder 100 is inserted into the fixing hole 602 and fixedly connected to the phase-separation cylinder 600; the sulfur slurry inlet pipe 400 and the extractant inlet pipe 500 both pass through the inner wall of the phase-separation cylinder 600, that is, the liquid inlet end of the sulfur slurry inlet pipe 400 and the liquid inlet end of the extractant inlet pipe 500 are both exposed on the outside of the phase-separation cylinder 600, the solid outlet 104 is located on the outside of the phase-separation cylinder 600, and the extraction phase outlet 102 is located on the inside of the phase-separation cylinder 600, and the extraction phase outlet 102 is connected to the phase-separation cavity 601. It can be understood that part of the structure of the extraction cylinder 100 is located in the phase separation chamber 601, and the extraction phase outlet 102 is located in the phase separation chamber 601, the remaining part of the structure of the extraction cylinder 100 is exposed on the outside of the phase separation cylinder 600, and the solid outlet 104 is exposed on the outside of the phase separation cylinder 600, so that the extraction mixed liquid flows into the phase separation chamber 601 through the extraction phase outlet 102, and impurities cannot pass through the extraction phase outlet 102, and thus flow out from the solid outlet 104 to the top of the phase separation cylinder 600.

[0056] like Figure 1 or Figure 3As shown, in one embodiment, the outer wall of the phase separation cylinder 600 adjacent to the bottom is provided with an extraction phase outlet pipe 603 connected to the phase separation chamber 601, so that the extracted mixed liquid after stratification enters the heating mechanism 30 through the extraction phase outlet pipe 603. Further, a control valve 604 is provided on the extraction phase outlet pipe 603. When the extracted mixed liquid enters the phase separation cylinder 600 for phase separation, the control valve 604 is in a closed state, so that the extracted mixed liquid is allowed to stand in the phase separation cylinder 600 for a predetermined time until the upper layer is the water phase and the lower layer is the extraction phase of sulfur and the extractant, and then the control valve 604 is opened to allow the extraction phase to enter the heating mechanism 30 through the extraction phase outlet pipe 603. When all the extraction phases enter the heating mechanism 30 through the extraction phase outlet pipe 603, the control valve 604 is immediately closed, and the water phase stays in the phase separation cylinder 600 at this time, so that the separation of the water phase and the extraction phase can be achieved.

[0057] like Figure 1 , Figure 3 and Figure 5 As shown, in one embodiment, the phase separation tube 600 includes a vertical placement portion 610 and an inclined mounting portion 620, the fixing hole 602 is opened at the end of the inclined mounting portion 620 away from the vertical placement portion 610, and the extraction phase outlet pipe 603 is arranged on the outer wall of the vertical placement portion 610 adjacent to the bottom. In this embodiment, the phase separation chamber 601 includes a first cavity 6011 arranged on the vertical placement portion 610 and a second cavity 6012 arranged on the inclined mounting portion 620, the first cavity 6011 is connected to the second cavity 6012, the extraction phase outlet pipe 603 is connected to the first cavity 6011, and the extraction phase outlet 102 is connected to the second cavity 6012; when the vertical placement portion 610 is vertically placed on a horizontal plane, the inclined mounting portion 620 is in an inclined state relative to the horizontal plane, so that the extraction tube 100 is better inclined relative to the horizontal plane.

[0058] like Figure 2 As shown, in one embodiment, there is a preset angle θ between the center line X of the vertical placement part 610 and the center line Y of the inclined installation part 620. Since the center line of the vertical placement part 610 and the center line of the inclined installation part 620 form a preset angle, when the phase separation cylinder 600 is placed on a horizontal plane, the vertical placement part 610 is placed vertically, so that the inclined installation part 620 has an inclined angle relative to the horizontal plane, and under the rotation of the spiral blade 300, the impurities can flow out from the solid outlet 104 quickly. Further, the preset angle θ is 5° to 35°. In this embodiment, the preset angle θ is 15°, which can better control the extraction efficiency between the sulfur slurry and the extractant, and at the same time, the amount of the extraction mixed liquid lifted to the extraction phase outlet 102 by the spiral blade 300 is more reasonable, and the extraction mixed liquid can flow out from the extraction phase outlet 102 in time, avoiding the waste of the extraction mixed liquid caused by excessive extraction mixed liquid flowing out of the solid outlet 104.

[0059] Furthermore, if Figure 2 As shown, the center line Z of the extraction cylinder 100 is parallel to the center line Y of the inclined mounting portion 620, that is, the center line Z of the extraction cylinder 100 is parallel to the center line Y of the inclined mounting portion 620, so that the extraction cylinder 100 is tilted relative to the horizontal plane, so that impurities can quickly flow out from the solid outlet 104.

[0060] Furthermore, combined with Figure 2 and Figure 5 As shown, the center line Z of the extraction cylinder 100 is arranged to coincide with the axis of the rotating shaft 220 , so that the spiral blades 300 are better inclined relative to the horizontal plane and impurities can flow out through the solid outlet 104 better.

[0061] Furthermore, the vertical placement portion 610 and the inclined mounting portion 620 are integrally formed structures, so that the vertical placement portion 610 and the inclined mounting portion 620 are firmly connected, and the structure of the phase separation tube 600 is more compact. In other embodiments, the vertical placement portion 610 and the inclined mounting portion 620 are not limited to an integrally formed structure. For example, the vertical placement portion 610 and the inclined mounting portion 620 are formed separately and fixedly connected by welding.

[0062] However, after the sulfur slurry and the extract are mixed and extracted, since the impurities do not participate in the extraction, the impurities are transmitted upward through the spiral blades 300 until they flow out from the solid outlet 104 to the top of the phase separation cylinder 600. When the impurities pass through the solid outlet 104, a small amount of the extraction mixed liquid is brought out, resulting in a large waste of the extraction mixed liquid.

[0063] In order to reduce the waste of extraction mixture, Figure 3 and Figure 4 As shown, in one embodiment, a reflux zone is provided at the top of the phase separation cylinder 600, the solid outlet 104 is arranged toward the reflux zone, a plurality of reflux holes 605 are provided in the reflux zone, and each reflux hole 605 is connected to the phase separation chamber 601, so that impurities are carried out of the extraction mixed liquid through the solid outlet 104 and enter the phase separation cylinder 600 through the reflux hole 605, thereby reducing the waste of the extraction mixed liquid. In this embodiment, each reflux hole 605 is connected to the second cavity 6012.

[0064] To prevent impurities and the extraction mixture carried by the impurities from flowing out from the top of the phase separation tube 600 along the side of the phase separation tube 600, as shown in FIG. Figure 4As shown, in one embodiment, a liquid baffle plate 630 is convexly provided on the periphery of the top of the phase separation tube 600, and the liquid baffle plate 630 is arranged in the reflux area so that the impurities flow out from the solid outlet 104 and enter the reflux area, while the impurities and the extraction mixed liquid carried by the impurities are blocked by the liquid baffle plate 630 and then stay in the reflux area, and the extraction mixed liquid carried by the impurities can enter the phase separation tube 600 through the reflux hole 605, thereby reducing the possibility of waste of the extraction mixed liquid due to the extraction mixed liquid carried by the impurities. In this embodiment, the inclined mounting portion 620 is inclined relative to the horizontal plane, and the liquid baffle plate 630 is arranged in the reflux area so that the extraction mixed liquid brought out by the impurities can quickly flow into the phase separation chamber 601, and can prevent the extraction mixed liquid from flowing out of the periphery of the top of the phase separation tube 600.

[0065] like Figure 2 As shown, in one embodiment, a support plate 640 and a mounting plate 650 are further provided on the top of the phase-separation tube 600, and two ends of the support plate 640 are respectively fixedly connected to the top of the phase-separation tube 600 and the mounting plate 650, and the rotating driving member 210 is fixed on the mounting plate 650 to ensure that the rotating driving member 210 drives the rotating shaft 220 to rotate normally, and the support plate 640 serves as a transition between the mounting plate 650 and the phase-separation tube 600.

[0066] like Figure 7 As shown, the present disclosure also provides a sulfur slag recovery device 10A, comprising a crushing mechanism 20, a heating mechanism 30 and an extraction and standing mechanism 10 of any of the above embodiments. The crushing mechanism 20 is connected to the sulfur slurry inlet pipe 400, and the extraction chamber 101 is connected to the heating mechanism 30 through the extraction phase outlet pipe 603.

[0067] The above-mentioned sulfur slag recovery device 10A not only reduces environmental pollution, but also can realize continuous and automated production of lime sulfur, thereby improving the production efficiency of lime sulfur.

[0068] like Figure 7 As shown, the crushing mechanism 20 includes a crushing barrel 21 and a crushing assembly 22. A sulfur slag inlet pipe 21a, a water inlet pipe 21b and a slurry inlet pipe 21c are provided on the top of the crushing barrel 21. A crushing chamber 21p is formed in the crushing barrel 21. The sulfur slag inlet pipe 21a, the water inlet pipe 21b and the slurry inlet pipe 21c are all connected to the crushing chamber 21p. The crushing chamber 21p is connected to the sulfur slurry inlet pipe 400 through the slurry inlet pipe 21c. Furthermore, a mechanical pump 21d is provided on the slurry inlet pipe 21c.

[0069] Furthermore, the crushing assembly 22 includes a crushing drive 22a and a crushing blade 22b, wherein the crushing drive 22a is located on the outer wall of the crushing cylinder 21, and the crushing blade 22b is located in the crushing cylinder 21 and fixedly connected to the driving end of the crushing drive 22a. In this embodiment, the crushing drive 22a is a crushing motor.

[0070] It can be understood that sulfur slag is added to the crushing chamber 21p from the sulfur slag inlet pipe 21a, water is added from the water inlet pipe 21b, and the crushing drive 22a drives the crushing blades 22b to rotate, so that the sulfur slag and water are stirred into sulfur slurry. Under the action of the mechanical pump 21d, the sulfur slurry is sucked into the slurry inlet pipe 21c from the crushing chamber 21p, and then enters the extraction chamber 101 through the sulfur slurry inlet pipe 400, thereby performing an extraction operation of mixing the sulfur slurry with the extract.

[0071] like Figure 7 As shown, in one embodiment, the heating mechanism 30 includes a heating element 31 and a cooking cylinder 32, a partition 32a is provided inside the cooking cylinder 32 to divide the inner cavity of the cooking cylinder 32 into a heating cavity 32b and a cooking cavity 32c, the heating element 31 is located in the heating cavity 32b, a feed pipe 32d and an air outlet pipe 32e are provided on the top of the cooking cylinder 32, the feed pipe 32d and the air outlet pipe 32e are both connected to the cooking cavity 32c, and the extraction cavity 101 is connected to the cooking cavity 32c through the extraction phase outlet pipe 603. In this embodiment, the heating element 31 is an electric heating wire or heat transfer oil.

[0072] It can be understood that after the extraction mixture is left in the phase separation cylinder 600 for a period of time, the extraction mixture is separated into a water phase and an extraction phase, and then the control valve 604 is opened to allow the extraction phase to enter the cooking chamber 32c, and then quicklime and water are added in sequence from the feed pipe 32d, so that the quicklime and water enter the cooking chamber 32c, and under the action of the heating element 31, that is, the electric heating wire is heated or the heat transfer oil is ignited, the extractant is evaporated, and the steam is discharged from the outlet pipe 32e, thereby producing lime sulfur. The sulfur slag recovery device 10A allows the sulfur slag to be recycled, reduces the waste of sulfur slag produced by the sulfur filter, and improves the production efficiency of lime sulfur.

[0073] Compared with the prior art, the present invention has the following advantages, including but not limited to:

[0074] 1. After adding sulfur slurry and extractant to the above-mentioned extraction and standing mechanism 10, sulfur slurry is mixed in the extractant, and the rotating shaft 220 is driven to rotate by the rotating driving member 210, so that the rotating shaft 220 drives the spiral blade 300 to rotate, and the extraction mixed liquid is transmitted upward with the rotation of the spiral blade 300, so that the extraction mixed liquid flows out from the extraction phase outlet 102, and part of the extraction mixed liquid is retained in the extraction chamber 101 through the filtering area, while impurities brought by the sulfur slurry, such as silicon dioxide, are transmitted through the spiral blade 300. Since one end of the spiral blade 300 at least extends to the position corresponding to the solid outlet 104, and the extraction cylinder 100 is inclined relative to the horizontal plane, the impurities are guided by the spiral blade 300 and the impurities themselves Under the gravity of the impurities, the impurities finally flow out through the solid outlet 104, which is convenient for subsequent processing, and the extraction and standing mechanism 10 can realize extraction and filtration at the same time, without the need to set up an additional filter screen, the extraction efficiency is high, and the structure of the extraction and standing mechanism 10 is compact.

[0075] 2. The extraction mixed liquid flows out through the extraction phase outlet 102 and enters the phase separation cylinder 600. The impurities flow out from the solid outlet 104 and are located at the top of the phase separation cylinder 600. The extraction mixed liquid carried by the impurities enters the phase separation cylinder 600 through the reflux hole 605, so that the extraction mixed liquid is located in the phase separation chamber 601 and remains stationary. Such a structure can realize the recycling of the extraction mixed liquid carried by the impurities, thereby reducing the waste of the extraction mixed liquid.

[0076] 3. By setting the stirring rod 110, on the basis of the rotation transmission of the spiral blade 300, the stirring rod 110 can accelerate the mixing degree and speed between the sulfur slurry and the extractant, thereby improving the extraction efficiency and extraction rate.

[0077] 4. Since the center line of the vertical placement portion 610 and the center line of the inclined installation portion 620 form a preset angle, when the phase separation tube 600 is placed on a horizontal plane, the vertical placement portion 610 is placed vertically, so that the inclined installation portion 620 has an inclination angle relative to the horizontal plane. Under the rotation of the spiral blade 300, impurities can quickly flow out from the solid outlet 104.

[0078] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
