Description

Technical Field

[0001] This utility model relates to the field of furan resin production technology, specifically to a production apparatus. Background Technology

[0002] Furan resin is an oxygen-containing five-membered ring compound composed of a furan ring and a benzene ring. It has good mechanical properties and chemical stability, so it can be used to manufacture various complex high-strength materials. However, in the production and processing of furan resin, a reaction vessel is required to completely synthesize the furan resin.

[0003] A search revealed an existing patent (publication number: CN219942804U) that discloses a urea-formaldehyde reactor for furan resin production, comprising a reaction vessel. The reaction vessel is internally equipped with a first stirring mechanism and a second stirring mechanism. A feed pipe is fixedly connected to the top of the reaction vessel, and a discharge pipe is fixedly connected to the bottom. A purification box is fixedly installed at the top of the outer side of the reaction vessel. Two sets of filter boxes are slidably installed inside the purification box. A sealing plate is provided on the front of each filter box, and a handle is provided on the front of the sealing plate. An exhaust fan is fixedly installed on the outer side of the reaction vessel, below the purification box. The input end of the exhaust fan is connected to the bottom of the purification box via a connecting pipe. Compared with existing urea-formaldehyde reactors for furan resin production, this invention improves the overall mixing uniformity and practicality of the urea-formaldehyde reactor for furan resin production through its design.

[0004] In the above scheme, the activated carbon filter cartridge inside the filter box is replaced by a pull-out method. However, whether the activated carbon filter cartridge is saturated with adsorption needs to be judged manually. If it is replaced before it is saturated, it will cause waste and increase costs. If it is not replaced in time after it is saturated, it will affect the effect of its waste gas adsorption treatment and thus cause inconvenience in its use.

[0005] In view of this, the present invention proposes a production device. Utility Model Content

[0006] This invention proposes a production device that solves the problem of inconvenient timely replacement of activated carbon filter elements in related technologies.

[0007] The technical solution of this utility model is as follows: A production device includes a vessel body; a discharge pipe fixedly connected to the bottom end of the vessel body; a controller fixedly connected to the upper end of the front side of the vessel body; a top cover fixedly connected to the top end of the vessel body by bolts; a feed pipe fixedly connected to one side of the top end of the top cover; a one-way air inlet valve fixedly connected to the other side of the top end of the top cover; a servo motor fixedly connected to the middle position of the top end of the top cover; the output end of the servo motor passes through the top cover and is fixedly connected to a stirring rod through a coupling; a sliding sleeve is provided on the surface of the stirring rod; a stirring blade and a scraper are fixedly connected to the surface of the sliding sleeve respectively; and the device is assembled with the stirring rod. The assembly on the stirring rod and sliding sleeve is used to disassemble, maintain, or replace the stirring blades or scraper; an adsorption box is fixedly connected to the upper end of one side of the vessel body, with one side of the top of the adsorption box connected to the upper end of the vessel body through a conduit, and a negative pressure fan fixedly connected to the bottom end of the adsorption box; an installation groove is provided on one side of the adsorption box, and a sealing plate is fixedly connected to one side of the adsorption box by bolts; activated carbon adsorption plates are arranged at equal intervals inside the adsorption box; and an early warning assembly is assembled on the inner wall of the adsorption box, which is used to support the installation of the activated carbon adsorption plates and to provide an early warning when the activated carbon adsorption plates are saturated.

[0008] The early warning component includes: symmetrically formed fixing grooves on the inner wall of the adsorption box, wherein a pressure sensor is fixedly connected to the inner bottom wall of one side of the fixing groove; symmetrically fixedly connected sliding rods to the inner bottom wall of the fixing grooves, wherein the surface of the sliding rods is slidably connected to sliding grooves; and a return spring wound around the surface of the sliding rods, wherein the two ends of the return springs are fixedly connected to the bottom end of the sliding plate and the inner bottom wall of the fixing groove, respectively.

[0009] Preferably, a groove is provided on one side of the top of the sliding plate, and sliding strips that slide in cooperation with the inside of the groove are fixedly connected to both sides of the bottom of the activated carbon adsorption plate.

[0010] Preferably, the sealing plate is convex in shape, and the area of ​​the cross-section of the sealing plate on the side away from the adsorption box is larger than the area of ​​the cross-section inside the mounting groove.

[0011] Preferably, a sealing ring is fixedly connected to one side of the surface of the sealing plate, and the sealing ring is in the shape of a U-shape.

[0012] Preferably, the mounting assembly includes: a limiting groove formed on one side of the surface of the stirring rod, and a bolt hole formed on the other side of the surface of the stirring rod; a limiting block fixedly connected to the inner wall of the sliding sleeve, and a fixing bolt movably connected to the other side of the surface of the sliding sleeve and threadedly engaged with the inside of the bolt hole.

[0013] Preferably, the limiting block and the interior of the limiting groove form a sliding structure, and the limiting groove and the limiting block are rectangular in shape.

[0014] Preferably, a guide platform is fixedly connected to the inner bottom wall of the vessel, and the guide platform is funnel-shaped.

[0015] Preferably, one side of the scraper is in contact with the inner wall of the vessel, and the bottom end of the scraper is in contact with the inner wall of the guide platform.

[0016] The beneficial effects of this utility model are as follows:

[0017] In this invention, when the negative pressure fan is not working, the activated carbon adsorption plate will gradually become saturated with adsorbed particles and other impurities. At this time, its own weight will gradually increase. The pressure sensor detects the force applied to it by the slide. As the activated carbon adsorption plate gradually becomes saturated, the pressure detected by the pressure sensor also increases and is displayed on the display screen of the controller. When the pressure sensor detects a value exceeding a predetermined value, it means that the corresponding activated carbon adsorption plate has become saturated and needs to be replaced. This avoids the problem that in the traditional method, the top activated carbon adsorption plate comes into contact with the exhaust gas first and becomes saturated first. However, in the traditional method, all three activated carbon adsorption plates are usually replaced at the same time, and the replacement is mostly determined manually. This makes it impossible to replace the activated carbon adsorption plates according to their actual adsorption status. This results in the traditional method of not replacing saturated activated carbon adsorption plates in time, which reduces the exhaust gas adsorption effect, or replacing them all at once, which leads to the replacement of some unsaturated activated carbon adsorption plates, resulting in high maintenance costs.

[0018] This invention utilizes a sliding sleeve to slide between the sliding sleeve and the surface of the stirring rod, and then uses an installation component to limit and fix the sliding sleeve after it slides. This allows for the disassembly and assembly of the stirring blade or scraper with the surface of the stirring rod, facilitating thorough cleaning and maintenance of the stirring blade and scraper after disassembly, or replacement of the corresponding damaged stirring blade and scraper. This avoids the excessive maintenance costs associated with replacing the entire stirring assembly when individual parts are damaged, thus improving its practicality. Attached Figure Description

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0028] A preferred embodiment of the production apparatus provided by this utility model is, for example... Figures 1 to 6The following describes a production apparatus: a vessel body 5; a discharge pipe 10 fixedly connected to the bottom of the vessel body 5; a controller 16 fixedly connected to the upper end of the front of the vessel body 5; a top cover 1 fixedly connected to the top of the vessel body 5 by bolts; a feed pipe 2 fixedly connected to one side of the top of the top cover 1; and a one-way air inlet valve 4 fixedly connected to the other side of the top of the top cover 1; a servo motor 3 fixedly connected to the middle position of the top of the top of the top cover 1; the output end of the servo motor 3 passing through the top cover 1 and fixedly connected to a stirring rod 7 via a coupling; a sliding sleeve 17 provided on the surface of the stirring rod 7; and stirring blades 8 and scrapers 9 fixedly connected to the surface of the sliding sleeve 17; and mounting brackets assembled on the stirring rod 7 and the sliding sleeve 17. Component 6 is used to disassemble, maintain, or replace the stirring blade 8 or scraper 9; an adsorption box 15 is fixedly connected to the upper side of one side of the vessel body 5, and the top of the adsorption box 15 is connected to the upper part of the vessel body 5 through a conduit. A negative pressure fan 12 is fixedly connected to the bottom of the adsorption box 15. An installation groove 19 is opened on one side of the adsorption box 15, and a sealing plate 13 is fixedly connected to one side of the adsorption box 15 by bolts. Activated carbon adsorption plates 14 are arranged at equal intervals inside the adsorption box 15; an early warning component 18 is assembled on the inner wall of the adsorption box 15. The early warning component 18 is used to support the installation of the activated carbon adsorption plates 14 and to issue an early warning after the activated carbon adsorption plates 14 are saturated.

[0029] The warning component 18 includes: a fixing groove 1804 symmetrically formed on the inner wall of the adsorption box 15, wherein a pressure sensor 1805 is fixedly connected to the inner bottom wall of one side of the fixing groove 1804; a sliding rod 1803 symmetrically fixedly connected to the inner bottom wall of the fixing groove 1804, and a sliding groove 1807 slidably connected to the surface of the sliding rod 1803; and a return spring 1806 wound around the surface of the sliding rod 1803, with both ends of the return spring 1806 fixedly connected to the bottom end of the sliding plate 1801 and the inner bottom wall of the fixing groove 1804, respectively.

[0030] In this embodiment, the activated carbon adsorption plate 14 will gradually become saturated with adsorbed particles and other impurities, and its own weight will gradually increase. At this time, the pressure sensor 1805 detects the force applied to it by the slide 1807. As the activated carbon adsorption plate 14 gradually becomes saturated, the pressure detected by the pressure sensor 1805 also increases, and is displayed on the display screen on the controller 16. When the value detected by the pressure sensor 1805 exceeds the predetermined value, it means that the corresponding activated carbon adsorption plate 14 has become saturated and needs to be replaced.

[0031] In a further preferred embodiment of the present invention, a groove 1807 is provided on one side of the top of the sliding plate 1801, and a sliding strip 1802 is fixedly connected to both sides of the bottom end of the activated carbon adsorption plate 14 and slides 1802 that slide in cooperation with the inside of the groove 1807.

[0032] In this embodiment, the sliding of the slider 1802 and the inside of the groove 1807 is used to realize the rapid sliding assembly and disassembly of the activated carbon adsorption plate 14.

[0033] In a further preferred embodiment of the present utility model, the sealing plate 13 is convex in shape, and the area of the cross-section of the side of the sealing plate 13 away from the adsorption box 15 is larger than the area of the cross-section inside the installation groove 19.

[0034] In this embodiment, the relatively large-area sealing plate 13 is used to completely cover and seal the installation groove 19 after installation.

[0035] In a further preferred embodiment of the present utility model, a sealing ring 20 is fixedly connected to one side of the surface of the sealing plate 13, and the sealing ring 20 is in a shape of a square frame.

[0036] In this embodiment, the sealing ring 20 is used to further improve the sealing performance between the sealing plate 13 and the inside of the installation groove 19 after installation. Embodiment <着

[0037] On the basis of Embodiment 1, a preferred embodiment of the production device provided by the present utility model is as Figures 1 to 6 shown: The installation component 6 includes: a limiting groove 601 opened on one side of the surface of the stirring rod 7, and a bolt hole 604 opened on the other side of the surface of the stirring rod 7; a limiting block 602 fixedly connected to the inner wall of the sliding sleeve 17, and a fixing bolt 603 movably connected to the other side of the surface of the sliding sleeve 17 and threadedly engaged with the inside of the bolt hole 604.

[0038] In this embodiment, by loosening the fixing bolt 603 until it completely disengages from the inside of the bolt hole 604 and then sliding the sliding sleeve 17 downward until it completely separates from the bottom end of the stirring rod 7, the stirring blade 8 and the scraping plate can be disassembled, facilitating cleaning, maintenance or replacement of the damaged stirring blade 8 or scraping plate 9. During installation, the reverse operation can be performed.

[0039] In a further preferred embodiment of the present utility model, a sliding structure is formed between the limiting block 602 and the inside of the limiting groove 601, and the limiting groove 601 and the limiting block 602 are rectangular in shape.

[0040] In this embodiment, the sliding between the limiting block 602 and the inside of the limiting groove 601 is used to improve the sliding stability of the sliding sleeve 17 and ensure that the hole on one side of the sliding sleeve 17 is on the same vertical axis as the bolt hole 604, facilitating the subsequent screwing of the fixing bolt 603 into the bolt hole 604.

[0041] In a further preferred embodiment of the present utility model, a material guiding platform 11 is fixedly connected to the inner bottom wall of the kettle body 5, and the material guiding platform 11 is funnel-shaped.

[0042] In this embodiment, the funnel-shaped material guiding platform 11 is used to facilitate the guiding of the reacted furan resin material, making it easier to be discharged through the discharge pipe 10.

[0043] In a further preferred embodiment of this utility model, one side of the scraper 9 is in contact with the inner wall of the vessel body 5, and the bottom end of the scraper 9 is in contact with the inner wall of the guide platform 11.

[0044] In this embodiment, a scraper 9 of a suitable shape is used to effectively prevent furan resin material from remaining on the inner wall of the reactor body 5, thereby improving material utilization.

[0045] The working principle of this product is as follows: First, furan resin raw material is added through feed pipe 2. Then, the servo motor 3 is started to drive the stirring rod 7 to rotate, which in turn drives the stirring blade 8 and scraper 9 to rotate and stir and mix the material. During this process, the negative pressure fan 12 is started to draw the waste gas generated inside the vessel 5 into the adsorption box 15, and the activated carbon adsorption plate 14 adsorbs it. Then, the gas after adsorption treatment is discharged through the exhaust hole at the bottom of the negative pressure fan 12. A one-way air inlet valve 4 is set to supplement the external air during the negative pressure suction process of the negative pressure fan 12 to ensure that the air pressure inside the vessel 5 is constant. After the stirring reaction is completed, the valve on the discharge pipe 10 is opened to discharge the material.

[0046] Furthermore, when the negative pressure fan 12 is not operating, the activated carbon adsorption plate 14 will gradually become saturated with adsorbed particles and other impurities. At this point, its weight will gradually increase, causing the sliding plate 1801 to slide down and compress the return spring 1806. The pressure sensor 1805 detects the force applied by the slide groove 1807. As the activated carbon adsorption plate 14 gradually becomes saturated, the pressure detected by the pressure sensor 1805 also increases, and this is displayed on the screen of the controller 16. When the value detected by the pressure sensor 1805 exceeds a predetermined value, the display on the controller 16 highlights the corresponding pressure sensor 1805 number, such as by turning the detected value red or making it bold, thus serving as a reminder. The staff replaces the corresponding activated carbon adsorption plates 14, which effectively avoids the problem of reduced waste gas adsorption effect due to the traditional method of not replacing saturated activated carbon adsorption plates 14 in time, or the large maintenance cost caused by replacing some unsaturated activated carbon adsorption plates 14 when replacing them all at once. At the same time, when replacing, the bolts on the sealing plate 13 are loosened and the sealing plate 13 is removed. Then, the activated carbon adsorption plate 14 can be slidably disassembled and installed by sliding the slider 1802 and the sliding groove 1807. At the same time, when the negative pressure fan 12 is working, the activated carbon adsorption plate 14 may slide down due to suction. At this time, the pressure sensor 1805 does not record the reading to avoid misunderstanding by the staff.

[0047] Meanwhile, when it is necessary to thoroughly clean the inner wall of the vessel body 5 or to maintain or replace the stirring blades 8 and scrapers 9, first open the top cover 1, then loosen the fixing bolts 603 until they are completely disengaged from the bolt holes 604, and then slide the sliding sleeve 17 down until it is completely separated from the bottom of the stirring rod 7. This allows the stirring blades 8 and scrapers 9 to be disassembled, making it convenient to clean, maintain, or replace the damaged stirring blades 8 or scrapers 9. When installing, put the sliding sleeve 17 on the surface of the stirring rod 7 and make the limiting block 602 slide into the limiting groove 601. Then slide the sliding sleeve 17 to the appropriate position and tighten the fixing bolts 603 into the corresponding bolt holes 604.

[0048] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described above, and the electrical connection should be completed by referring to the working sequence of each electrical component. The detailed connection methods are well-known technologies in the field. The above mainly introduces the working principle and process, and will not describe the electrical control.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
