Description

Technical Field

[0002] The sulfur wet granulation process involves first introducing liquid sulfur into a liquid sulfur granulation distributor located above the granulation machine, creating a uniformly distributed liquid sulfur line. This line is then smoothly introduced into a cooling pool, where it forms droplets. These droplets are evenly distributed in the cooling water, where they gradually cool and solidify into spherical sulfur particles. The solidified spherical sulfur particles settle to the bottom of the cooling water in the cooling pool and are continuously discharged from the bottom. The discharged spherical sulfur particles, accompanied by a large amount of cooling water, require dehydration on a dewatering screen to reduce the moisture content of the product and avoid any impact on the quality of the sulfur product.

[0003] However, in the existing dehydration operation, due to the high vibration frequency of the dehydration screen in the sulfur production system, the spherical sulfur particles will leave the dehydration screen in a relatively short period of time, making it difficult to fully dehydrate the spherical sulfur particles, resulting in a high moisture content in the product and reduced product quality.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0027] Unless otherwise specified, the relative arrangement of the parts and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0028] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0029] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below".

[0031] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] See also Figures 1 to 3 , shows a schematic diagram of a sulfur production system in the present application, which at least includes: a wet granulation module 1, a sulfur dewatering screen 2 and a product output module 3; the sulfur dewatering screen 2 is arranged between the wet granulation module 1 and the product output module 2; the sulfur dewatering screen 2 includes a sieve plate 21, a blowing assembly 22 and a base 23; the sieve plate 21 is movably connected to the base 23; a driving assembly 24 is provided on the base 23, and the driving assembly 24 is connected to the sieve plate 21; the blowing assembly 22 is arranged above the sieve plate 21, and the blowing assembly 22 is used to blow air to the spherical sulfur particles during the process of the sieve plate 21 dehydrating the spherical sulfur particles; the output end of the wet granulation module 1 is connected to the sieve plate 21, and the output end of the sieve plate 21 is connected to the product output module 3.

[0033] In the sulfur production system provided in this embodiment, during use, a wet granulation module 1 produces spherical sulfur granules containing a high moisture content. These spherical sulfur granules containing a high moisture content are then fed into a sulfur dewatering screen 2 for dehydration. Specifically, a drive assembly 24 drives the screen plate to vibrate, causing the spherical sulfur granules to vibrate and dehydrate. Simultaneously, a blowing assembly 22 blows air onto the spherical sulfur granules on the screen plate 21, removing moisture adhering to the surface of the spherical sulfur granules and accelerating the dehydration rate of the spherical sulfur granules. After dehydration is completed, the dehydrated spherical sulfur granules are collected, assembled, and then output by a product output module 3. The sulfur production system provided by the present utility model improves the dehydration efficiency of the spherical sulfur granules, avoiding the technical problem in the prior art of insufficient dehydration of the spherical sulfur granules, which results in excessive moisture in the sulfur product.

[0034] Optionally, refer to Figure 1 The product output module 3 in the present invention includes a conveyor belt 31 and a receiving device 32 . The conveyor belt 31 is connected to the output end of the sulfur dewatering screen 1 ; the receiving device 32 is arranged above the conveyor belt 31 .

[0035] In this embodiment, the dehydrated spherical sulfur particles are stored by the storage device 32 , and the stored sulfur products are output by the conveyor belt 31 .

[0036] Optionally, refer to Figure 2 、 Figure 3 and Figure 6 The spherical sulfur particles described in the present invention move in a first direction 4 on the sieve plate 21; the sieve plate 21 further comprises two side plates 211, which are respectively arranged on both sides of the sieve plate 21 in a second direction 5, the second direction 5 being perpendicular to the first direction 4, and both being located on the plane of the sieve plate 21; the blowing assembly 22 comprises an air source 221, a main air duct 222, and a plurality of air distribution ducts 223 arranged on the main air duct 222, the main air duct 222 being arranged along the second direction 5. The main air duct 222 is further provided with a first air inlet 224 at the midpoint in the second direction 5; the air distribution duct 223 is arranged along the first direction 4; the first air inlet 224 is connected to the air source 221; the main air duct 222 is arranged between the two side panels 211 and above the sieve plate 21; multiple air distribution ducts 223 are arranged in sequence in the second direction 5, and multiple first air outlets 225 are provided on the lower side of the air distribution duct 223; the main air duct 222 and the air distribution duct 223 are both parallel to the sieve plate 21.

[0037] In this embodiment, a dewatering screen for sulfur is provided, and its blowing assembly 22 includes an air source 221, a main air duct 222 and a plurality of air distribution ducts 223. During actual use, the air source 221 supplies air to the main air duct 222 through the first air inlet 224, and enters each air distribution duct 223 through the main air duct 222, and blows air to the spherical sulfur particles on the sieve plate 21 through the first air outlet 225 on the air distribution duct 223. The air is blown away by the moisture attached to the surface of the spherical sulfur particles, thereby improving the dehydration efficiency of the spherical sulfur particles and reducing the moisture in the sulfur product.

[0038] Furthermore, the wind source 221 described in this embodiment can be a blower, diverter or other device connected to a factory wind source, and the factory wind source is used to dry the moisture attached to the surface of the spherical sulfur particles, thereby saving energy.

[0039] Furthermore, the main air duct 222 and the air distribution duct 223 described in this embodiment can be selected as metal tubes.

[0040] Furthermore, the first air outlet 225 described in this embodiment can be a small hole with a diameter between 2 mm and 4 mm. Specifically, the diameter of the first air outlet 225 can be any one of 2 mm, 3 mm or 4 mm.

[0041] Furthermore, the distance between the main air duct 222 and the air distribution duct 223 and the sieve plate 21 in this embodiment should be between 3 cm and 5 cm, and specifically, can be 3 cm, 4 cm or 5 cm.

[0042] Furthermore, the main air duct 222 and the air distribution duct 223 described in this embodiment are movably arranged above the sieve plate 21, and their heights can be adjusted, so that those skilled in the art can select a suitable height to blow air to the spherical sulfur particles on the sieve plate 21 according to actual use requirements to ensure the dehydration effect.

[0043] Furthermore, in this embodiment, the number of the first air outlets 225 on the air distribution duct 223 gradually decreases from a position near the first air inlet 224 to a position near the side panel 211. In actual use, since the internal pressure of the air distribution duct 223 near the first air inlet 224 is higher than that of the air distribution duct 223 near the side panel 211, by reducing the number of first air outlets 225 near the side panel 211, the air pressure of each first air outlet 225 is similar, thereby avoiding the technical problem of uneven air output and inconsistent air drying effect on the spherical sulfur granules.

[0044] Optionally, refer to Figure 4 and Figure 6 In the present invention, the length of the air distribution duct 223 gradually shortens from the midpoint of the main air duct 222 to both ends.

[0045] In this embodiment, since the internal pressure of the air duct near the first air inlet 224 is higher than that of the air duct 223 near the side wall 211, the length of the air duct 223 near the side panel 211 is shortened so that the air outlet pressures of each first air outlet 225 are close, thereby avoiding the technical problem that the air pressure of the air duct 223 near the side panel 211 is small, resulting in the air duct 223 near the side panel 211 having a poor drying effect on the spherical sulfur particles.

[0046] Optionally, refer to Figure 2 、 Figure 3 and Figure 5 The blowing assembly 22 described in the present invention includes an air source 221 and an air distribution plate 226; the air distribution plate 226 is arranged above the sieve plate 21; a buffer cavity 227 is arranged in the air distribution plate 226; a plurality of second air outlets 228 are arranged on the lower side of the air distribution plate 226, and the second air outlets 228 are connected to the buffer cavity 227; a second air inlet 229 is arranged on the upper side of the air distribution plate 226; the second air inlet 229 is connected to the air source 221.

[0047] In this embodiment, the blowing assembly 22 may further include an air distribution plate 226, a second air inlet 229 is provided on the upper side of the air distribution plate 226, a second air outlet 228 is provided on the lower side, and a buffer chamber 227 is provided inside the air distribution plate 226. During use, the air source 21 is connected through the second air inlet 229, and air is supplied to the buffer chamber 227 through the air source 221, so that the incoming air is evenly distributed in the buffer chamber 227 and is discharged through the second air outlet 228, blowing air onto the spherical sulfur particles on the sieve plate 21, drying the moisture attached to the surface of the spherical sulfur particles, and reducing the moisture contained in the sulfur product.

[0048] Furthermore, the second air outlets 228 in this embodiment should be evenly distributed on the lower side of the air distribution plate 226. Specifically, the second air outlets 228 can be arranged in a matrix, and the spacing between any two closest second air outlets 226 can be selected to be 40 mm to 60 mm, specifically 40 mm, 45 mm, 50 mm, 55 mm, or 60 mm. It should be noted that those skilled in the art can select the specific arrangement and spacing of the second air outlets 228 based on actual usage requirements. This embodiment merely provides one implementation method.

[0049] Furthermore, the second air outlet 228 in this embodiment can be a small hole with a diameter between 2 mm and 4 mm. Specifically, the diameter of the second air outlet 228 can be any one of 2 mm, 3 mm or 4 mm.

[0050] Furthermore, the air distribution plate 226 in this embodiment should be movably arranged above the sieve plate 21, and its height can be adjusted, so that technical personnel in this field can select a suitable height to blow air on the spherical sulfur particles on the sieve plate 1 according to actual use requirements to ensure the dehydration effect.

[0051] Optionally, a partition is provided in the buffer chamber 227 in the present invention, which evenly divides the buffer chamber 227 into multiple sub-buffer chambers; there are multiple second air inlets 229, and one second air inlet 229 is connected to one sub-buffer chamber; each sub-buffer chamber is connected to the second air outlet 228, and the number of connected second air outlets 228 is the same.

[0052] In this embodiment, the buffer chamber 227 is divided into multiple sub-buffer chambers by a partition, and each sub-buffer chamber is connected to the air source 221 through the second air inlet 229. In actual use, the wind pressure entering the sub-buffer chamber is further balanced through the multiple sub-buffer chambers, so that the air outlet pressures of each second air outlet 228 are close, ensuring balanced blowing of the spherical sulfur particles on the sieve plate 21.

[0053] Furthermore, the wind source 221 described in the present invention may provide wind with a pressure of 0.6 MPa to 0.8 MPa and a wind temperature of 60 degrees Celsius to 80 degrees Celsius.

[0054] In this embodiment, wind source 221 can provide wind with a pressure of 0.6 MPa to 0.8 MPa and a temperature of 60°C to 80°C. This range of wind pressure and temperature is particularly suitable for drying spherical sulfur granules. In actual use, excessive wind pressure can cause the spherical sulfur granules to fly away, while excessively low wind pressure can result in poor drying. A wind temperature between 60°C and 80°C effectively dries the surface moisture of the spherical sulfur granules without the safety risks associated with a continuous increase in the surface temperature of the sieve plate 21 due to excessively high wind temperature. Specifically, wind source 221 can provide wind at temperatures of 60°C, 70°C, and 80°C.

[0055] Optionally, refer to Figure 2 and Figure 3 In the present invention, the forward direction of the spherical sulfur particles on the sieve plate 21 is the first direction 4; the sieve plate 21 includes a first side 212 and a second side 213 that are opposite to each other in the first direction 4, and the first side 212 is provided with a discharge port 214; a plurality of baffles 215 are provided on the upper surface of the sieve plate 21, and the baffles 215 are arranged between the first side 212 and the second side 213, and there are gaps between the baffles 215; the baffles 215 are perpendicular to the first direction 4.

[0056] In this embodiment, the second side 213 is arranged below the discharge port in the wet granulation module 1, so that the formed spherical sulfur particles fall onto the sieve plate 21, and the sieve plate 21 is driven to vibrate by the driving component 24, so as to dehydrate the spherical sulfur particles. During the dehydration process, the baffle 215 plays a role in blocking the spherical sulfur particles, extending the dehydration time of the spherical sulfur particles on the sieve plate 21, thereby improving the dehydration effect. At the same time, during the dehydration process, the moisture attached to the spherical sulfur particles is blown by the blowing component 22, thereby accelerating the dehydration rate of the spherical sulfur particles and reducing the moisture content in the sulfur product; after completing the sulfur dehydration operation, the spherical sulfur particles enter the product output module 3 from the discharge port 214 for processing.

[0057] Furthermore, the baffle 215 in this embodiment can be made of a metal plate or a silicone plate, and the height of the baffle 215 can be selected from 1 cm to 3 cm, specifically 1 cm, 2 cm, or 3 cm. It should be noted that those skilled in the art can select the material and height of the baffle 14 according to actual production and use requirements. This embodiment only provides one implementation method.

[0058] Furthermore, the first side 212 described in the present invention is arranged higher than the second side 213 .

[0059] In this embodiment, the first side 212 is higher than the second side 213 , so that the sieve plate 21 forms a certain slope, thereby further increasing the residence time of the spherical sulfur particles on the sieve plate 21 and improving the dehydration effect.

[0060] Furthermore, the inclination angle of the sieve plate 1 formed from the second side 13 to the first side 12 may be 5° to 9°, specifically, 5°, 7° or 9°.

[0061] Furthermore, the driving assembly 24 described in the present invention may include two driving members, which are respectively arranged on both sides of the sieve plate 21 and connected to the sieve plate 21 .

[0062] In this embodiment, the driving members are arranged on both sides of the sieve plate 21 so that the vibration of the sieve plate 1 is evenly distributed and maintenance is convenient.

[0063] Furthermore, the driving member described in this embodiment can be specifically selected as a vibration motor or a common motor with an exciter.

[0064] Optionally, a discharge hopper 25 and an exhaust fan 26 are further provided between the discharge port 214 and the product output module 3. The side wall of the discharge hopper 25 is provided with an exhaust port 251, and the exhaust fan 26 is connected to the discharge hopper 25 through the exhaust port 251; the discharge port 214 is connected to the discharge hopper 25; and the discharge hopper 25 is connected to the product output module 3.

[0065] In this embodiment, a discharge hopper 25 is provided between the discharge port 214 and the product output module 3. This hopper 25 positions the spherical sulfur particles that have passed the dehydration process, allowing them to enter the next process. Simultaneously, an exhaust fan 26 removes any steam that may be present on the spherical sulfur particles during the discharge process, further reducing the moisture content of the sulfur product.

[0066] Furthermore, the exhaust fan 26 described in this embodiment can be specifically selected as a bag type exhaust fan, or a filter can be provided at the exhaust port 251 to prevent the spherical sulfur particles from being sucked away.

[0067] Optionally, refer to Figure 1 The wet granulation module 1 of the present invention includes a liquid sulfur input device 11, a liquid sulfur distributor 12 and a wet granulator 13; the liquid sulfur input device 11 is connected to the liquid sulfur distributor 12; the liquid sulfur distributor 12 is arranged above the wet granulator 13; the output end of the wet granulator 13 is connected to the sieve plate 21, which is used to input the generated spherical sulfur particles onto the sieve plate 21.

[0068] In this embodiment, liquid sulfur is introduced into a liquid sulfur distributor 12 through a liquid sulfur input device 11 to generate a uniformly distributed liquid sulfur line. The liquid sulfur line is then smoothly introduced into the coolant of a wet granulator 13 to generate droplets. These droplets are uniformly distributed in the coolant and gradually cool and solidify in the coolant to form spherical sulfur particles. The solidified spherical sulfur particles settle to the bottom of the wet granulator 13 and are continuously discharged from the bottom onto the sieve plate 21 of the sulfur dewatering screen 2 for dehydration.

[0069] Optionally, refer to Figure 1 In the present invention, a gas collecting hood 14 is further provided above the liquid sulfur distributor 12 .

[0070] In this embodiment, a gas collecting hood 14 is provided above the liquid sulfur distributor 12 , and the harmful gases generated during the wet granulation process are collected and treated through the gas collecting hood 13 to avoid safety risks.
