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.

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. 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.

[0030] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[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 dewatering screen described in the present application, which comprises at least: a sieve plate 1, a blowing assembly 2, and a base 3; the sieve plate 1 is movably connected to the base; a driving assembly 31 is provided on the base 3, and the driving assembly 31 is connected to the sieve plate 1; the blowing assembly 2 is provided above the sieve plate 1, and the blowing assembly 2 is used to blow air to the spherical sulfur particles while the sieve plate 1 is dehydrating the spherical sulfur particles.

[0033] In the sulfur dewatering screen provided in this embodiment, during use, the spherical sulfur particles on the sieve plate 1 are blown by the blowing component 2, and the moisture attached to the surface of the spherical sulfur particles is taken away by the blowing, thereby accelerating the dehydration rate of the spherical sulfur particles and improving the dehydration effect of the spherical sulfur particles, thereby avoiding the technical problem of insufficient dehydration effect on the spherical sulfur particles in the prior art, resulting in excessive moisture in the sulfur product.

[0034] Optionally, refer to Figure 3 and Figure 4The spherical sulfur particles described in the utility model move in a first direction 4 on the sieve plate 1; the sieve plate 1 also includes two side plates 11, which are respectively arranged on both sides of the sieve plate 1 in a second direction 5, the second direction 5 is perpendicular to the first direction 4, and are both on the plane of the sieve plate 1; the blowing assembly 2 includes an air source 21, a main air duct 22, and a plurality of air distribution pipes 23 arranged on the main air duct 22, the main air duct 22 is arranged along the second direction 5, and a first air inlet 221 is also provided at the midpoint of the main air duct 22 in the second direction 5; the air distribution pipe 23 is arranged along the first direction 4; the first air inlet 221 is connected to the air source 21; the main air duct 22 is arranged between the two side plates 11 and above the sieve plate 1; the plurality of air distribution pipes 23 are arranged in sequence in the second direction 5, and a plurality of first air outlets 231 are provided on the lower side of the air distribution pipe 23; the main air duct 22 and the air distribution pipe 23 are both parallel to the sieve plate 1.

[0035] In this embodiment, a dewatering screen for sulfur is provided, and its blowing assembly 2 includes an air source 21, a main air duct 22 and a plurality of air distribution ducts 23. During actual use, the air source 21 supplies air to the main air duct 22 through the first air inlet 221, enters each air distribution duct 23 through the main air duct 22, and blows air to the spherical sulfur particles on the sieve plate 1 through the first air outlet 231 on the air distribution duct 23. 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.

[0036] Furthermore, the wind source 21 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.

[0037] Furthermore, the main air duct 22 and the air distribution duct 23 described in this embodiment can be selected as metal tubes.

[0038] Furthermore, the first air outlet 231 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 231 can be any one of 2 mm, 3 mm and 4 mm.

[0039] Furthermore, the distance between the main air duct 22 and the air distribution duct 23 and the sieve plate 1 in this embodiment should be between 3 cm and 5 cm, and specifically, can be selected as 3 cm, 4 cm to 5 cm.

[0040] Furthermore, the main air duct 22 and the air distribution duct 23 described in this embodiment are movably arranged above the sieve plate 1, 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 1 according to actual use requirements to ensure the dehydration effect.

[0041] Furthermore, in this embodiment, the number of the first air outlets 231 on the air distribution duct 23 gradually decreases as it moves from a position near the first air inlet 221 to a position near the side panel 11. In actual use, because the pressure in the air distribution duct 23 near the first air inlet 221 is higher than that in the air distribution duct 23 near the side wall 11, by reducing the number of first air outlets 231 near the side panel 11, the air pressure at each first air outlet 231 is made similar, thereby avoiding the technical problem of uneven air output that leads to inconsistent air drying effects on the spherical sulfur granules.

[0042] Optionally, in the present invention, the length of the air distribution duct 23 gradually shortens from the midpoint of the main air duct 22 to its two ends, that is, from the position close to the first air inlet 221 to the position close to the side panel 15, the length of the two adjacent air distribution ducts 23 gradually shortens.

[0043] In this embodiment, since the pressure of the air duct 23 near the first air inlet 221 is higher than that of the air duct 23 near the side wall 15, the length of the air duct 23 near the side panel 15 is shortened so that the air outlet pressures of each first air outlet 231 are close, thereby avoiding the technical problem that the air pressure of the air duct 23 near the side panel 15 is small, resulting in the air duct 23 near the side panel 15 having a poor drying effect on the spherical sulfur particles.

[0044] Optionally, refer to Figure 5 and Figure 6 The blowing assembly 2 described in the present invention includes an air source 21 and an air distribution plate 24; the air distribution plate 24 is arranged above the sieve plate 1 and parallel to the sieve plate 1; a buffer cavity 25 is arranged in the air distribution plate 24; a plurality of second air outlets 241 are arranged on the lower side of the air distribution plate 24, and the second air outlets 241 are connected to the buffer cavity 25; a second air inlet 242 is arranged on the upper side of the air distribution plate 24; the second air inlet 242 is connected to the air source 21.

[0045] In this embodiment, the blowing assembly 2 may further include an air distribution plate 24, a second air inlet 242 is provided on the upper side of the air distribution plate 24, a second air outlet 241 is provided on the lower side, and a buffer chamber 25 is provided inside the air distribution plate 24. During use, the air source 21 is connected through the second air inlet 242, and air is supplied to the buffer chamber 25 through the air source 21, so that the incoming air is evenly distributed in the buffer chamber 25 and is discharged through the second air outlet 241 to blow air onto the spherical sulfur particles on the sieve plate 1, dry the moisture attached to the surface of the spherical sulfur particles, and reduce the moisture contained in the sulfur product.

[0046] Furthermore, the second air outlets 241 in this embodiment should be evenly distributed on the lower side of the air distribution plate 24. Specifically, the second air outlets 241 can be arranged in a matrix, and the spacing between any two closest second air outlets 241 can be selected to be 40 mm to 60 mm, and specifically, 40 mm, 45 mm, 50 mm, 55 mm, and 60 mm. It should be noted that those skilled in the art can select the specific arrangement and spacing of the second air outlets 241 based on actual usage requirements. This embodiment merely provides one implementation method.

[0047] Furthermore, the second air outlet 241 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 241 can be any one of 2 mm, 3 mm and 4 mm.

[0048] Furthermore, the air distribution plate 24 in this embodiment should be movably arranged above the sieve plate 1, 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.

[0049] Optionally, a partition 251 is provided in the buffer chamber 25 described in the present invention, and the buffer chamber 25 is evenly divided into multiple sub-buffer chambers 252 by the partition 251; at the same time, there are multiple second air inlets 242, and one second air inlet 242 is connected to one sub-buffer chamber 252; and each sub-buffer chamber 252 is connected to the second air outlet 242, and the number of connected second air outlets 241 is the same.

[0050] In this embodiment, the buffer chamber 25 is divided into multiple sub-buffer chambers 252 by a partition 251, and each sub-buffer chamber 252 is connected to the air source 21 through the second air inlet 242. In actual use, the wind pressure entering the sub-buffer chamber 252 is further balanced through the multiple sub-buffer chambers 252, so that the air outlet pressures of each second air outlet 241 are close, ensuring balanced blowing of the spherical sulfur particles on the sieve plate 1.

[0051] Furthermore, the wind source 21 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.

[0052] In this embodiment, the wind source 21 can provide wind with a pressure of 0.6 MPa to 0.8 MPa and a temperature of 60°C to 80°C. Wind pressure and temperature within this range are more suitable for air-drying spherical sulfur granules. In actual use, excessive wind pressure will blow away the spherical sulfur granules, while excessively low wind pressure will result in poor drying effect. When the wind temperature is between 60°C and 80°C, the air drying effect on the surface moisture of the spherical sulfur granules is better, and the safety risk caused by the continuous increase in the surface temperature of the sieve plate 1 due to excessively high wind temperature is avoided. Specifically, the wind source 21 can provide wind with wind temperatures of 60°C, 70°C, and 80°C.

[0053] Optionally, the forward direction of the spherical sulfur particles described in the present invention on the sieve plate 1 is a first direction 4; the sieve plate 1 includes a first side 12 and a second side 13 opposite to each other in the first direction 4, and the first side 12 is provided with a discharge port 14; a plurality of baffles 15 are provided on the upper surface of the sieve plate 1, and the baffles 15 are arranged between the first side 12 and the second side 13, and there are intervals between the baffles 15; the baffles 15 are perpendicular to the first direction 4.

[0054] In this embodiment, the second side is arranged below the discharge port of the cooling pool in the sulfur production system, so that the spherical sulfur particles formed in the cooling pool fall onto the sieve plate 1, and the sieve plate 1 is driven to vibrate by the driving component 31, so as to dehydrate the spherical sulfur particles. During the dehydration process, the baffle 15 plays a role in blocking the spherical sulfur particles, extending the dehydration time of the spherical sulfur particles on the sieve plate 1, 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 2, 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 next process from the discharge port 14 for processing.

[0055] Furthermore, the baffle 15 in this embodiment can be made of a metal plate or a silicone plate, and the height of the baffle 15 can be selected from 1 cm to 3 cm, specifically 1 cm, 2 cm, and 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.

[0056] Optionally, a discharge hopper 6 and an exhaust fan 7 are provided on the lower side of the discharge port 14 described in the present invention, and an exhaust port 61 is provided on the side wall of the discharge hopper 6 , and the exhaust fan 7 is connected to the discharge hopper 6 through the exhaust port 61 .

[0057] In this embodiment, a discharge hopper 6 is provided below the discharge port 14 to position the spherical sulfur particles after dehydration, allowing them to enter the next process. Simultaneously, an exhaust fan 7 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.

[0058] Furthermore, the exhaust fan 7 described in this embodiment can be specifically selected as a bag-type exhaust fan, or a filter can be provided at the exhaust port 61 to prevent the spherical sulfur particles from being sucked away.

[0059] Optionally, the first side 12 described in the present invention is arranged higher than the second side 13 .

[0060] In this embodiment, the first side 12 is higher than the second side 13, so that the sieve plate 1 forms a certain slope, thereby further increasing the residence time of the spherical sulfur particles on the sieve plate 1 and improving the dehydration effect.

[0061] Furthermore, the inclination angle of the sieve plate 1 formed from the second side 13 to the first side 12 is 5° to 9°, and specifically, can be selected as 5°, 7° or 9°.

[0062] Optionally, the driving assembly 31 described in the present invention includes two driving members, which are respectively arranged on both sides of the sieve plate 1 and connected to the sieve plate 1 .

[0063] In this embodiment, the driving members are arranged on both sides of the sieve plate 1 so that the vibration of the sieve plate 1 is evenly distributed and maintenance is convenient.

[0064] Furthermore, the driving member described in this embodiment can be specifically selected as a vibration motor or a common motor with an exciter.

[0065] Optionally, a dehydration trough is further provided on the sieve plate in the present invention, which is used to guide and discharge the moisture released from the sulfur particles during the dehydration process to avoid moisture accumulation on the sieve plate.

[0066] In this embodiment, a dewatering trough is provided on the sieve plate to guide and discharge liquid, such as water, generated during the dehydration of the sulfur particles. Specifically, the dewatering trough can be provided on the second side of the sieve plate and connected to the water recovery device.
