Description

Technical Field

[0001] The present invention relates to a sugar factory production and processing dust treatment equipment, in particular to a sugar factory production and processing dust treatment equipment applied in the field of dust treatment technology. Background Art

[0002] When sugar factories make sugar, a large amount of dust is often produced. In order to ensure hygiene, sugar factories need to have good ventilation inside and outside the factory. During ventilation, dust is often easily introduced into the ventilation ducts with the air. The dust in sugar factories is often sugar powder, which is easy to melt at high temperatures or when it encounters moisture, resulting in increased viscosity. It is easy to adhere to the ventilation ducts and is difficult to remove, and it is even easy to breed bacteria, which can easily cause gout to cause the hygiene standards in the factory to fail to meet the standards, affecting stable sugar production.

[0003] Therefore, it is urgent to provide a device that can separate the sugar powder dust and air in the ventilation duct, so as to reduce the amount of sugar powder adhering to the ventilation duct. Summary of the invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the sugar dust in the sugar factory is easily adhered to the ventilation duct along with the air, and is easily melted and bacteria are grown.

[0005] To solve the above problems, the present invention provides a dust treatment device for production and processing in a sugar factory, comprising two air ducts and a dust transfer bin fixedly connected between the two air ducts, the dust transfer bin comprising a double-position cylinder and an outward expansion cover fixedly connected to one end of the air duct near the air inlet of the double-position cylinder, the double-position cylinder and the outward expansion cover are communicated with each other, an end of the outward expansion cover away from the double-position cylinder is fixedly connected with a liquid inlet pipe, the liquid inlet pipe is communicated with an external water source, a liquid discharge pipe is fixedly connected to the lower end of the double-position cylinder, the liquid inlet pipe and the liquid discharge pipe are both communicated with the transfer bin, a cross filter assembly is arranged inside the double-position cylinder, the cross filter assembly comprises a central shaft rotatably connected to the front and rear inner walls of the double-position cylinder, two filter cylinders and a plurality of evenly distributed water-absorbing filter screens clamped in the filter cylinder, two connecting rods are fixedly connected between the filter cylinder and the central shaft, a motor is fixedly connected to the middle part of one end of the double-position cylinder away from the liquid inlet pipe, the motor rotates 180 degrees each time, the output end of the motor movably passes through the double-position cylinder and is fixedly connected to the central shaft, and one of the filter cylinders is coaxially arranged with the two air ducts.

[0006] In the above-mentioned sugar factory production and processing dust treatment equipment, the air in the sugar factory can be separated and treated before entering the ventilation duct. Under the setting of the cross-filtration component, the water-absorbent filter can be humidified to effectively capture the sugar powder. At the same time, through cross-filtration, the sugar powder adhering to the water-absorbent filter can be effectively removed while the air is continuously filtered. Compared with the existing technology, it effectively ensures the efficient and stable separation of sugar powder from the air.

[0007] As a further improvement of the present application, the apertures of the multiple water-absorbent filter screens are different, and the apertures of the multiple water-absorbent filter screens gradually decrease in a direction away from the liquid inlet pipe.

[0008] As a further improvement of the present application, two coaxial through holes are drilled on the double-position cylinder, the two through holes correspond to the two air ducts respectively, and the apertures of the filter cylinder and the through holes are consistent, and both ends of the filter cylinder are in contact with the front and rear inner walls of the double-position cylinder, and the inner diameter of the air duct is not less than the aperture of the through holes.

[0009] As a further improvement of the present application, a flushing hole corresponding to the external expansion cover is also drilled on the double-position cylinder. The flushing hole is symmetrical with the center of one of the through holes. The aperture of the flushing hole is smaller than the inner diameter of the external expansion cover and larger than the outer diameter of the filter cylinder.

[0010] As another improvement of the present application, the filter cylinder includes a fixed half-cylinder, a displacement cylinder and two semi-separation strips respectively arranged between the left and right ends of the two cylinders which are symmetrical in upper and lower directions. The water-absorbent filter screen is fixedly connected to the fixed half-cylinder, and the water-absorbent filter screen is only in contact with the displacement cylinder. The connection point between the connecting rod and the filter cylinder is located on the fixed half-cylinder.

[0014] As another improvement supplement of the present application, a plurality of pressure sensors corresponding to a plurality of water-absorbing filters are installed on the inner wall of the displacement cylinder, and when the semi-detached rod is completely located in the rectangular strip, the pressure sensor contacts the outer ring of the water-absorbing filter.

[0016] In summary, the sugar powder can be separated when the air from the sugar factory enters the ventilation duct. By setting a cross-filtration component with two filter cartridges, when too much sugar powder is separated, the two filter cartridges can be exchanged, so that the filter cartridge with more sugar powder is expanding outward and desorbing the sugar powder, and the other filter cartridge can continue to separate the sugar powder. Through the above-mentioned cross-filtration method, the sugar powder adhered to the water-absorbing filter screen can be effectively removed and desorbed while the air is continuously filtered. Compared with the existing technology, the efficient and stable separation of sugar powder from the air is effectively guaranteed. In addition, with the setting of the detachable filter cartridge, the permeability of the water-absorbing filter screen can be monitored in real time, which is convenient for timely replacement and desorption, thereby effectively ensuring the dust treatment efficiency.

DETAILED DESCRIPTION

[0029] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0030] The first implementation method:

[0031] Figure 1-2 A dust treatment device for production and processing in a sugar factory is shown, comprising two air ducts 1 and a dust transfer bin fixedly connected between the two air ducts 1, the dust transfer bin comprising a double-position cylinder 21 and an external expansion cover 22 fixedly connected to one end of the air duct 1 close to the air inlet of the double-position cylinder 21, the double-position cylinder 21 and the external expansion cover 22 are connected to each other, an end of the external expansion cover 22 away from the double-position cylinder 21 is fixedly connected to a liquid inlet pipe 31, the liquid inlet pipe 31 is connected to an external water source, a lower end of the double-position cylinder 21 is fixedly connected to a liquid discharge pipe 32, and the liquid inlet pipe 31 and the liquid discharge pipe 32 are both connected to the transfer bin, as shown in FIG. Figure 3 and Figure 5 Before use, the ends of the two air guide tubes 1 that are away from each other are connected to the ventilation duct, and the air guide tube 1 on the same side as the liquid inlet pipe 31 is the air inlet direction. When the ventilation system of the sugar factory is working, when the air enters the device, it first passes through the filter cartridge 51 and then passes through the multiple water-absorbent filter screens 52 therein in turn to separate the sugar powder from the air, and then the separated air is discharged into the ventilation duct through the air guide tube 1 on the other side.

[0032] It is worth noting that the external water source connected to the liquid inlet pipe 31 is hot water, and the temperature of the hot water is not lower than 60° C., so that when the hot water is used to flush the water-absorbing filter 52, it can dissolve the powdered sugar adhering to the surface of the water-absorbing filter 52 faster and better.

[0033] like Figure 4 and Figure 5 A cross-filter assembly is provided inside the double-position cylinder 21, and the cross-filter assembly includes a central shaft 53 rotatably connected to the front and rear inner walls of the double-position cylinder 21, two filter cylinders 51, and a plurality of evenly distributed water-absorbing filters 52 clamped in the filter cylinder 51, the apertures of the plurality of water-absorbing filters 52 are different, and the apertures of the plurality of water-absorbing filters 52 gradually decrease in the direction away from the liquid inlet pipe 31, so that sugar powder of different particle sizes in the air can be filtered, so that the separation effect between the sugar powder and the air is better, and two connecting rods are fixedly connected between the filter cylinder 51 and the central shaft 53, and a motor 4 is fixedly connected to the middle of one end of the double-position cylinder 21 away from the liquid inlet pipe 31, such as Figure 7The motor 4 rotates 180° each time, so that the two filter cartridges 51 are interchanged with each other after each rotation of the motor 4. The output end of the motor 4 movably penetrates the double-position cylinder 21 and is fixedly connected to the central axis 53. One of the filter cartridges 51 is coaxially arranged with the two air guide pipes 1, so that when the air enters the double-position cylinder 21, it can always be filtered by the multiple water-absorbent filters 52 in one of the filter cartridges 51, thereby effectively ensuring that the air is not easily discharged from the ventilation duct without passing through.

[0034] like Figure 4 Two coaxial through holes 8 are drilled on the double-position cylinder 21, and the two through holes 8 correspond to the two air guide pipes 1 respectively, and the apertures of the filter cylinder 51 and the through holes 8 are consistent, and both ends of the filter cylinder 51 are in contact with the front and rear inner walls of the double-position cylinder 21, and the inner diameter of the air guide pipe 1 is not less than the aperture of the through hole 8, so that the air can completely enter the corresponding filter cylinder 51, and it is not easy for some air to escape into the double-position cylinder 21.

[0035] like Figure 6 A flushing hole 7 corresponding to the external expansion cover 22 is also drilled on the double-position cylinder 21. The flushing hole 7 is symmetrical with one of the through holes 8. The aperture of the flushing hole 7 is smaller than the inner diameter of the external expansion cover 22 and larger than the outer diameter of the filter cylinder 51. When the water-absorbent filter screen 52 in the filter cylinder 51 is flushed, the water flow entering the filter cylinder 51 can fall into the double-position cylinder 21 along the space between the filter cylinder 51 and the flushing hole 7, and then be discharged from the drain pipe 32, effectively ensuring the continuous desorption of sugar powder on the water-absorbent filter screen 52.

[0036] During use, the filter cartridge 51 is first sprayed with water through the liquid inlet pipe 31 at regular intervals to wet the multiple water-absorbing filter screens 52, thereby effectively improving the adhesion and capture ability of the sugar powder. Then, the motor 4 is used to control the water-absorbing filter screen 52 to rotate 180°, so that the two filter cartridges 51 are swapped. The filter cartridge 51 with the wet water-absorbing filter screen 52 faces the through hole 8 and continues to filter and separate the sugar powder in the air. At the same time, the filter cartridge 51 with more sugar powder adhered to it faces the liquid inlet pipe 31. At this time, hot water can be injected into the double-position cylinder 21 through the liquid inlet pipe 31, so that the sugar powder adhered to the water-absorbing filter screen 52 can be melted with the hot water and desorbed from it. Then the drain pipe 32 is opened, and the hot water flow can be discharged from the drain pipe 32. It is worth noting that the drain pipe 32 can be connected to an external water pipe and connected to a water storage tank, so that the discharged water can be stored for easy recycling and reuse, thereby effectively saving water resources.

[0037] In the above-mentioned sugar factory production and processing dust treatment equipment, the air in the sugar factory can be separated and treated before entering the ventilation duct. Under the setting of the cross-filtration component, the water-absorbent filter 52 can be humidified to effectively capture the sugar powder. At the same time, the cross-filtration method can be used to achieve the effective removal of the sugar powder adhering to the water-absorbent filter 52 while continuously filtering the air. Compared with the existing technology, it effectively ensures the efficient and stable separation of sugar powder from the air.

[0038] The second implementation method:

[0039] Based on the first embodiment, this embodiment improves the specific arrangement of the filter cartridge 51, and the rest of the configuration remains the same as the first embodiment.

[0040] like Figure 8 The filter cartridge 51 includes a fixed half-cylinder 511 and a displacement cylinder 512 which are symmetrical in the upper and lower parts, and two half separation strips which are respectively arranged between the left and right ends of the two. The water-absorbing filter screen 52 is fixedly connected with the fixed half-cylinder 511, and the water-absorbing filter screen 52 and the displacement cylinder 512 are only in contact, so that the water-absorbing filter screen 52 does not restrict the mutual separation of the fixed half-cylinder 511 and the displacement cylinder 512. The connection point between the connecting rod and the filter cartridge 51 is located on the fixed half-cylinder 511. The half separation strips include a rectangular strip 61 fixedly connected to the fixed half-cylinder 511 and a plurality of rectangular strips fixedly connected to the displacement cylinder 512. A semi-detachable rod 62 is formed, and a plurality of insertion holes 601 are bored on the rectangular strip 61. The semi-detachable rod 62 and the insertion holes 601 are plugged and matched with each other, so that the fixed half cylinder 511 and the displacement cylinder 512 can be separated from each other, which is convenient for replacing the water-absorbing filter screen 52. At the same time, when the sugar powder on the plurality of water-absorbing filter screens 52 is rinsed and desorbed by hot water, the displacement cylinder 512 can be separated from the fixed half cylinder 511 downward, so that the water entering the filter cylinder 51 is easier to fall, and it is not easy for the water in the filter cylinder 51 to be difficult to discharge, thereby effectively ensuring the flushing efficiency of the water-absorbing filter screen 52.

[0041] like Figure 7 The rotation of the motor 4 can drive the two filter cartridges 51 to change positions. As the two filter cartridges 51 rotate, they change positions. Figure 8 , so that the upper and lower ends of the filter cylinder 51 after the transposition are reversed, that is, for the same filter cylinder 51, the directions of the fixed half cylinder 511 and the displacement cylinder 512 are opposite before and after the transposition, so that the filter cylinder 51 directly opposite to the through hole 8 always has the displacement cylinder 512 facing upward and the fixed half cylinder 511 facing downward, while the filter cylinder 51 corresponding to the flushing hole 7 always has the fixed half cylinder 511 facing upward and the displacement cylinder 512 facing downward.

[0042] When the filter cylinder 51 is facing the through hole 8, that is, the displacement cylinder 512 faces upward and the fixed half cylinder 511 faces downward, under the action of gravity, the half-release rod 62 is completely inserted into the insertion hole 601, and the lower end of the displacement cylinder 512 contacts the upper end of the rectangular strip 61, so that the water-absorbing filter screen 52 contacts the displacement cylinder 512 and the fixed half cylinder 511 at the same time. At this time, there is no gap between the three, and the air can be effectively filtered, and it is not easy to have obvious air discharged without being filtered; after a period of time , the motor 4 controls the two filter cylinders 51 to shift, and the filter cylinder 51 adsorbed with powdered sugar rotates to a position facing the flushing hole 7. At this time, the displacement cylinder 512 is at the bottom. Due to the action of gravity, the semi-detachment rod 62 gradually disengages from the insertion hole 601, so that the displacement cylinder 512 and the fixed semi-cylinder 511 are gradually separated. At this time, a certain gap is generated between the inner wall of the displacement cylinder 512 and the lower end of the water-absorbing filter screen 52, which is convenient for the flushing water to be discharged, and effectively avoids the situation where water in the filter cylinder 51 is difficult to discharge.

[0043] like Fig. 9 The semi-detachable rod 62 includes an inner rod 621 and an outer reducer sleeve 622 fixedly connected to the outer end of the inner rod 621. The outer reducer sleeve 622 is covered on the outer side of the inner rod 621 away from the displacement cylinder 512, and the outer reducer sleeve 622 is filled with a high-fluidity liquid, which can also be oil or other non-toxic and non-corrosive liquids. The socket 601 is divided into three sections. Along the direction toward the inside of the socket 601, the first section and the second section are both circular holes, and the third section is a spherical hole. The inner diameter of the second section is larger than the inner diameter of the first section and smaller than the inner diameter of the third section. The rod 621 includes a rod body and a spherical end fixedly connected to the rod body. The diameter of the spherical end is between the diameters of the first section and the second section of the socket 601. The sum of the diameter of the rod body of the inner rod 621 and the thickness of the outer reducer sleeve 622, which is twice the thickness, is smaller than the inner diameter of the first section of the socket 601. The outer reducer sleeve 622 is a flexible sealing structure, and the outer reducer sleeve 622 is made of hydrophobic and oleophobic material. When the inner rod 621 completely enters the socket 601, the connection between the outer reducer sleeve 622 and the inner rod 621 is located in the second section of the socket 601.

[0044] like Fig.10When the displacement cylinder 512 is located at the bottom, under the action of gravity, the high-fluidity liquid in the outer reducer sleeve 622 will move downward, causing the gap between the inner rod 621 and the inner wall of the socket 601 to gradually increase. At the same time, with the gravity of the displacement cylinder 512 itself, the semi-detached rod 62 will gradually move downward from the socket 601 relatively quickly, but will not completely detach from the socket 601, so that the fixed half cylinder 511 and the displacement cylinder 512 are in an incompletely separated state. After its position is changed, when the displacement cylinder 512 is located at the top, under the action of gravity, the semi-detached rod 62 moves into the socket 601, and the high-fluidity liquid moves toward the lower socket 601 again, so that it can fill the gap between the inner rod 621 and the socket 601, so that the displacement cylinder 512 gradually approaches the fixed half cylinder 511 and stably contacts with the rectangular bar 61, thereby effectively maintaining a stable filtration separation of sugar powder and air.

[0045] The inner wall of the displacement cylinder 512 is also equipped with a plurality of pressure sensors 501 corresponding to the plurality of water-absorbing filters 52, and when the half-separation rod 62 is completely located in the rectangular strip 61, the pressure sensor 501 contacts the outer ring of the water-absorbing filter 52. When the displacement cylinder 512 is at the bottom, it is separated from the water-absorbing filter 52 and no force data is generated. When it is at the top, it moves down close to the fixed half cylinder 511 and contacts the rectangular strip 61, the displacement cylinder 512 contacts the water-absorbing filter 52, so that the pressure sensor 501 contacts the water-absorbing filter 52. 1 generates force data, and after the water-absorbent filter screen 52 adheres to more sugar powder, its permeability decreases, and the resistance to air is greater, which will produce a greater outward squeezing force on the displacement cylinder 512, causing it to separate from the fixed half cylinder 511 again. At this time, the pressure sensor 501 loses the force data. A control chip can be installed on the double-position cylinder 21, and the motor 4 and the pressure sensor 501 are both connected to its signal. Based on the data changes of the pressure sensor 501, the motor 4 can intelligently control the displacement frequency of the two filter cylinders 51.

[0046] It is worth noting that the highly fluid liquid is preferably water. Since water has a high fluidity, the two filter cartridges 51 will be Fig.10 After the direction of the inner rod 621 changes, the water can flow downward under the action of gravity, so that the spherical end of the inner rod 621 faces downward. When the water moves downward, it can drive the outer reducer sleeve 622 to move downward and enter the insertion hole 601, thereby limiting the position of the displacement tube 512. Similarly, due to the fluidity of water, the limiting effect of the outer reducer sleeve 622 with water is limited. When the water-absorbing filter screen 52 intercepts more sugar powder and the permeability becomes worse, the gas resistance increases, and the displacement tube 512 is subjected to a greater force and automatically moves upward, so that the inner rod 621 can gradually separate from the rectangular bar 61, thereby making the force data of the pressure sensor 501 disappear, thereby achieving a reminder effect.

[0047] In addition, according to actual needs, the end surfaces of the fixed half-cylinder 511 and the displacement cylinder 512 that are close to each other are inlaid with magnetic strips, and there is a mutual adsorption force between the two corresponding magnetic strips, so that when the displacement cylinder 512 is located at the top, after it approaches the fixed half-cylinder 511, the mutual adsorption force between the two can make the two relatively stable and not easy to loosen under the impact of smaller air gases; when the displacement cylinder 512 is at the bottom, even if it is difficult to move downward and separate from the fixed half-cylinder 511 by its own gravity, when the liquid inlet pipe 31 sprays hot water into the filter cylinder 51, its gravity and impact force will assist the displacement cylinder 512 to move downward.

[0048] In summary, the sugar powder separation process can be carried out before the air in the sugar factory enters the ventilation duct. By setting a cross-filtration component with two filter cartridges, when there is too much sugar powder adhering to the filter screen, the liquid inlet pipe 31 first sprays a certain amount of water, and then the filter cartridges are exchanged, so that the filter cartridge 51 with more sugar powder is expanding outwardly to cover 22 and desorbing the sugar powder, and the other wetted filter cartridge 51 can continue to separate the sugar powder, thereby effectively capturing the sugar powder. Through the above-mentioned cross-filtration and desorption method, the sugar powder adhering to the water-absorbing filter screen 52 can be effectively removed while the air is continuously filtered. Compared with the prior art, the efficient and stable separation of sugar powder from the air is effectively guaranteed. In addition, with the setting of the detachable filter cartridge 51, the permeability of the water-absorbing filter screen 52 can be monitored in real time, which is convenient for timely replacement and desorption, thereby effectively ensuring the dust treatment efficiency.

[0049] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
