Description
Technical Field
[0001] This utility model relates to the field of nitrobenzeneacetic acid production technology, specifically to a glass cooling tower for nitrobenzeneacetic acid production. Background Technology
[0002] Nitrophenylacetic acid is an organic compound whose molecular structure contains a benzene ring, a nitro group, and an acetic acid group. It has specific chemical properties and applications. Nitrophenylacetic acid requires processing using a glass cooling tower during production.
[0003] A search revealed Chinese Patent Publication No. CN219714079U, which discloses a glass cooling tower for the production of p-nitrophenylacetic acid, belonging to the technical field of glass cooling towers. The tower includes a tower shell, with storage tanks fixedly connected to both sides of the inner wall of the shell. Several conveying ports are opened on the opposite sides of the two storage tanks. Two sliding grooves are formed on the lower surface of the inner wall of each storage tank. A common refrigeration component is installed in two adjacent sliding grooves. The refrigeration component includes two sliders, which are slidably connected in the two sliding grooves. The upper surfaces of the two sliders are fixedly connected to the lower surface of the same support plate. This glass cooling tower for the production of p-nitrophenylacetic acid, by incorporating a support plate and a refrigerator, facilitates heat exchange with the dry air at the bottom of the tower, removing heat and simultaneously cooling the air inside the tower more effectively. This allows for faster heat exchange with the cooling water containing heat, thereby improving the working efficiency of the cooling tower.
[0004] In the existing patent literature, the exhaust pipe, movable sleeve, and ventilator plate ventilate the tower. However, during ventilation, the air contains volatiles of nitrophenylacetic acid, which are absorbed by the activated carbon in the movable sleeve. However, due to the limited adsorption capacity of the activated carbon, some of the volatiles adhere to the ventilator plate through ventilation and accumulate there. At the same time, the ventilator plate and the movable sleeve are fixedly connected, making it difficult to replace the ventilator plate after long-term use. Therefore, a cooling tower with auxiliary replacement is needed to facilitate the replacement of the ventilator plate. Utility Model Content
[0005] The purpose of this invention is to provide a glass cooling tower for the production of nitrophenylacetic acid, thereby solving the problems mentioned in the background section. To solve these technical problems, this invention is achieved through the following technical solution:
[0006] This utility model relates to a glass cooling tower for the production of nitrophenylacetic acid, comprising:
[0007] A cooling assembly, comprising a movable sleeve and a vent plate; the vent plate is snapped onto the upper inner side of the movable sleeve.
[0008] The easy-to-replace component includes an annular hole, a magnetic block, an adsorption block, and a placement plate. The annular hole is located on the upper back of the movable sleeve. The magnetic block is fixed at both ends inside the annular hole. The adsorption block is fixed at both ends of the venting plate and is attracted to the magnetic block. The placement plate is fixed at one end inside the movable sleeve and is opposite to the annular hole.
[0009] Furthermore, a snap-fit block is fixedly connected to the back end of the venting disc, and the snap-fit block snaps into the center and outer side of the inner side of the annular hole.
[0010] Furthermore, a limiting rod passes through the upper and lower contact points of the snap-fit block and the movable sleeve, and a limiting hole is provided at the point where the snap-fit block passes through the limiting rod.
[0011] Furthermore, a limiting groove is provided at the connection between the movable sleeve and the limiting rod, and the limiting rod is threadedly connected to the limiting hole and the limiting groove.
[0012] Furthermore, the cooling assembly also includes a tower body and an exhaust pipe; the exhaust pipe is fixed to both sides of the top of the tower body, and the movable sleeve is fixed to the top of the exhaust pipe.
[0013] Furthermore, it also includes auxiliary limiting components;
[0014] The auxiliary limiting component includes an extension plate, an outer plate, and grooves; the extension plate is fixed to both sides of the back of the vent plate, the outer plate is fixed to the outer end of the extension plate, and the grooves are arranged in a set and are equally spaced on the outer plate.
[0015] Furthermore, the extension plate and the outer plate are engaged with the lower sides of the inner sides of the annular hole, and a set of docking blocks are provided on both sides of the lower back of the movable sleeve, and the docking blocks are engaged with the groove.
[0016] This utility model has the following beneficial effects:
[0017] This invention features a convenient replacement component. By pulling the ventilation disc outward, the disc moves through the annular hole, causing the adsorption block and magnetic block to separate. Simultaneously, the inner end of the ventilation disc separates from the placement plate, allowing the disc to pass through the annular hole and separate from the movable sleeve. This facilitates the removal of the ventilation disc and makes it easier to replace with a new one. It also prevents the ventilation disc from being affected by the accumulation of volatile substances on its surface. Attached Figure Description

[0026] Please see Figures 1-3 As shown, this utility model is a glass cooling tower for the production of nitrophenylacetic acid, comprising:
[0027] The cooling assembly includes a movable sleeve 13 and a vent plate 14; the vent plate 14 is snapped onto the upper inner side of the movable sleeve 13.
[0028] The cooling assembly also includes a tower body 11 and an exhaust pipe 12; the exhaust pipe 12 is fixed to both sides of the top of the tower body 11, and the movable sleeve 13 is fixed to the top of the exhaust pipe 12.
[0029] The tower body 11 is used as a cooling tower, the exhaust pipe 12 is used for ventilation inside the tower body 11, the movable sleeve 13 is used for connecting the inner activated carbon and the ventilation plate 14, and the ventilation plate 14 is used for ventilation of the exhaust pipe 12. The working principle of this component can be found in reference CN219714079U, a glass cooling tower for the production of p-nitrophenylacetic acid.
[0030] The components are easy to replace. The easy-to-replace components include an annular hole 21, a magnetic block 22, an adsorption block 23, and a placement plate 28. The annular hole 21 is opened on the upper back of the movable sleeve 13. The magnetic block 22 is fixed at both ends of the inner side of the annular hole 21. The adsorption block 23 is fixed at both ends of the ventilation plate 14. The adsorption block 23 is attracted to the magnetic block 22. The placement plate 28 is fixed at one end of the inner side of the movable sleeve 13 and is opposite to the annular hole 21.
[0031] The annular hole 21 is used for the movement of the ventilation plate 14 and the connection of the magnetic block 22. The magnetic block 22 is used for the connection of the adsorption block 23. The adsorption block 23 is used for the connection between the ventilation plate 14 and the magnetic block 22. The magnetic block 22 is attracted to the adsorption block 23 by magnetic force. The placement plate 28 is used for the placement of the inner end of the ventilation plate 14.
[0032] A snap-fit block 24 is fixedly connected to the back end of the vent plate 14, and the snap-fit block 24 snaps into the center and outer side of the annular hole 21.
[0033] A limiting rod 25 passes through the upper and lower contact points of the snap-fit block 24 and the movable sleeve 13, and a limiting hole 26 is provided at the contact point of the snap-fit block 24 and the limiting rod 25.
[0034] The movable sleeve 13 has a limiting groove 27 at the connection with the limiting rod 25, and the limiting rod 25 is threadedly connected to the limiting hole 26 and the limiting groove 27.
[0035] The snap-fit block 24 is used to connect the outer end of the vent plate 14 to the movable sleeve 13. The limiting rod 25 is used to limit the snap-fit block 24 and the vent plate 14 after snap-fit. The limiting hole 26 and the limiting groove 27 are used for the insertion and rotation of the limiting rod 25, pushing the vent plate 14. The vent plate 14 moves in the annular hole 21, so that the vent plate 14 drives the adsorption block 23 to be attracted to the magnetic block 22. The inner end of the vent plate 14 is placed on the placement plate 28, so that the vent plate 14 drives the snap-fit block 24 to snap-fit with the center of the inner side of the annular hole 21, so that the limiting groove 27 and the limiting hole 26 are aligned. The limiting rod 25 is rotated and inserted into the inner side of the limiting groove 27 and the limiting hole 26, thereby limiting the snap-fit block 24 and the vent plate 14 after insertion, and realizing the installation of the vent plate 14.
[0036] Working principle: When the venting disc 14 is not replaced, the magnetic block 22 and the adsorption block 23 are attracted to each other, and the inner end of the venting disc 14 is placed on the placement plate 28. When the venting disc 14 is replaced, the operator uses a tool to rotate the limiting rod 25, so that the limiting rod 25 is separated from the limiting groove 27 and the limiting hole 26. Then, the operator holds the locking block 24 and pulls the locking block 24 outward. The locking block 24 drives the venting disc 14 to move outward, so that the venting disc 14 drives the adsorption block 23 to separate from the magnetic block 22. At the same time, the inner end of the venting disc 14 separates from the placement plate 28, causing the venting disc 14 to move outward through the annular hole 21, so that the venting disc 14 is separated from the inside of the movable sleeve 13, thereby realizing the removal of the venting disc 14, which facilitates the replacement of the new venting disc 14.
[0037] Please see Figures 1-3 As shown, this embodiment, based on the above embodiment, further includes:
[0038] Auxiliary limit components;
[0039] The auxiliary limiting component includes an extension plate 31, an outer plate 32, and a groove 33; the extension plate 31 is fixed to both sides of the back of the vent plate 14, the outer plate 32 is fixed to the outer end of the extension plate 31, and the groove 33 is set in a group and is equally spaced on the outer plate 32.
[0040] The extension plate 31 is used to connect the external plate 32, the external plate 32 is used for the extension plate 31 to engage with the annular hole 21, and the groove 33 is used for the insertion of the mating block 34.
[0041] The extension plate 31 and the outer plate 32 are engaged with the lower sides of the inner sides of the annular hole 21. A set of docking blocks 34 are provided on both sides of the lower back of the movable sleeve 13. The docking blocks 34 are engaged with the groove 33.
[0042] The docking block 34 is used to connect the extension plate 31 and the outer side of the movable sleeve 13. There are three docking blocks 34 in each group. When the vent plate 14 is inserted into the upper inner side of the movable sleeve 13, it drives the extension plate 31, the outer connecting plate 32 and the lower inner side of the annular hole 21 to engage. At the same time, it drives the groove 33 to engage with the docking block 34, thereby further limiting the position of the vent plate 14 after insertion, so as to stabilize the connection between the vent plate 14 and the movable sleeve 13.
[0043] Working principle: When the component is not in use, the vent plate 14 is not engaged with the upper inner side of the movable sleeve 13. When the vent plate 14 is engaged with the upper inner side of the movable sleeve 13, the vent plate 14 drives the extension plate 31 to move towards the inner side of the annular hole 21, so that the extension plate 31 and the outer connecting plate 32 are engaged with the lower inner side of the annular hole 21, causing the groove 33 to engage with the docking block 34, thereby further limiting the position of the vent plate 14 after insertion.
