Description

Technical Field

[0001] This utility model relates to the field of liquid naphthalene curing technology, and in particular to a liquid naphthalene curing device. Background Technology

[0002] In industry, liquid naphthalene generally needs to be solidified to facilitate storage and transportation, meet specific industrial production needs, and improve safety.

[0003] Currently, two methods are generally used for curing liquid naphthalene: natural cooling curing and forced cooling curing. Among them, forced cooling curing is more efficient and can meet the needs of batch curing, so it is more widely used in actual industry.

[0004] A search revealed a liquid naphthalene curing device in the prior art document with patent authorization announcement number CN207998571U. This device is actually a processing equipment that uses equipment to achieve forced cooling and curing of liquid naphthalene. Its main structure includes a shell, an oil tank, a roller, a scraper, a collection box, and other components. An atomizing pipe is provided between the scraper and the oil tank along the axial direction of the roller. The atomizing pipe is connected to a steam pipe outside the device housing. Multiple spray holes for spraying water mist are evenly provided on the side of the atomizing pipe opposite to the roller.

[0005] It can be seen that the aforementioned curing device is mainly used for cutting the surface-cured naphthalene in the later stage of the liquid naphthalene curing process. In the early stage of curing, the roller rotates continuously towards the scraper and atomizer. The bottom of the roller is immersed in the liquid naphthalene in the oil tank. During the rolling process, the liquid naphthalene sticks to the roller. When the part of the roller with liquid naphthalene sticks to the cooling water inlet, it is cooled by the cooling water and turns into solid naphthalene, which is then scraped off by the scraper. However, this naphthalene curing process has the following problems: First, the liquid naphthalene is cured by cooling water alone, resulting in poor treatment effect and relatively low strength after curing. Second, scale will accumulate in the cooling water during long-term use, and scale and other impurities can easily be scraped into the liquid naphthalene, affecting its precision.

[0006] Based on this, the present invention optimizes the design to address the problems existing in the curing process of liquid refined naphthalene in the prior art, and proposes a new liquid refined naphthalene curing device to better solve the problems existing in the prior art.

A transmission gear is respectively installed inside each gear mounting cavity. Both ends of the gear shaft of the moving gear extend movably to the front and rear sides of the fixed frame. The gear shafts of the two transmission gears are connected by a transmission shaft. The bottom of each transmission gear meshes with the teeth on the top of the translation rack below it. The two transmission gears rotate together through a fixed axis to drive the translation rack meshing with them to move synchronously in the left and right directions. A drive motor is fixedly installed on the outer wall of the fixed frame at the rear. The motor shaft of the drive motor is fixedly connected to the outer end of the gear shaft of the transmission gear at the current position.

[0011] In any of the above embodiments, preferably, the naphthalene curing and cooling unit includes two symmetrically arranged sliding locking seats that are respectively engaged and locked into the lateral guide grooves at corresponding positions.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

After spraying, the naphthalene falls directly onto the naphthalene curing and cooling unit to achieve low-temperature cooling and solidification. After the naphthalene solidifies, the translation control mechanism controls it to be in place.

[0018] 2.

[0026] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of the present utility model, and are therefore merely examples and should not be construed as limiting the scope of protection of the present utility model. The specific structure of the present utility model is as follows: Figures 1-3 As shown in the image.

[0027] Example 1: A liquid naphthalene curing device includes a liquid naphthalene heat preservation tank 2 and a solid naphthalene collection tank 3, which are fixedly installed on the ground 1 at intervals. Liquid naphthalene is stored inside the liquid naphthalene heat preservation tank 2. A naphthalene curing and cooling unit is arranged above the liquid naphthalene heat preservation tank 2. Side support and guide mechanisms are symmetrically arranged on the front and rear sides of the naphthalene curing and cooling unit. The bottoms of the two side support and guide mechanisms are fixed on the ground 1. A liquid naphthalene conveying and spraying mechanism is arranged on the left side of the naphthalene curing and cooling unit. The lower end of the liquid naphthalene conveying and spraying mechanism is connected to the lower left side of the liquid naphthalene heat preservation tank 2 and the two are internally connected. The upper end of the liquid naphthalene conveying and spraying mechanism extends above the naphthalene curing and cooling unit. A solid naphthalene scraping mechanism is arranged above the solid naphthalene collection tank 3. A translation control mechanism is arranged on the right side of the naphthalene curing and cooling unit. The left end of the translation control mechanism is connected to the naphthalene curing and cooling unit.

[0028] Before operation, the liquid naphthalene curing equipment in this design requires the liquid naphthalene insulation tank 2 to be placed in the corresponding position, and the naphthalene curing cooling unit to be filled with sufficient low-temperature coolant.

[0029] The liquid refined naphthalene inside the liquid refined naphthalene heat preservation tank 2 is in a liquid state. According to the processing requirements, the liquid refined naphthalene needs to be cooled and solidified to generate solid refined naphthalene.

[0030] During operation, the liquid naphthalene conveying and spraying mechanism continuously pumps the liquid naphthalene in the liquid naphthalene insulation tank 2 upwards and sprays it downwards as needed. The sprayed liquid naphthalene falls onto the surface of the low-temperature naphthalene solidification and cooling unit, which allows the liquid naphthalene to cool and solidify on the surface of the naphthalene solidification and cooling unit. In order to ensure the cooling effect, the naphthalene solidification and cooling unit can be controlled to rotate at an appropriate speed on a fixed axis.

[0031] At this time, the combined effect of internal coolant heat conduction and rotary air cooling accelerates the adhesion and solidification speed of liquid refined naphthalene on the surface of the refined naphthalene solidification cooling unit. After the set cooling time, it can ensure that an appropriate amount of solidified refined naphthalene is solidified on the surface of the refined naphthalene solidification cooling unit.

[0032] At this time, the translation control mechanism controls the naphthalene curing and cooling unit to move to the right along the side support guide mechanism on both sides. When the translation reaches the lowering of the solid naphthalene scraping mechanism, the movement stops. At this time, it is necessary to control the solid naphthalene scraping mechanism to open and drive the corresponding scraping tool 28 to move down to the surface of the solid naphthalene scraping mechanism or close to it.

[0033] At this time, as the fixed axis of the solid naphthalene scraping mechanism rotates, the solid naphthalene adhering to the surface of the cooling metal roller 19 of the solid naphthalene scraping mechanism will continuously detach from the surface of the cooling metal roller 19 under the scraping action of the scraping blade 28, and then fall into the solid naphthalene collection tank 3. After the scraping is completed, the naphthalene curing and cooling unit is controlled to return to the left, and then the above steps are repeated. In this way, the liquid naphthalene in the liquid naphthalene heat preservation tank 2 is continuously cooled, cured and collected.

[0034] In any of the above embodiments, it is preferred that the liquid naphthalene conveying and spraying mechanism includes a curved rigid pipe 4, the lower end of which is fixed to the lower end of the left side wall of the liquid naphthalene heat preservation tank 2 and connected to its internal liquid collection chamber 5. The upper end of the curved rigid pipe 4 extends upward to the top of the naphthalene curing and cooling unit and its outlet end is vertically downward. A nozzle 6 is installed at the bottom of the outlet end of the curved rigid pipe 4, and the nozzle 6 is positioned directly opposite the naphthalene curing and cooling unit. A power delivery pump 7 is installed in the lower vertical section of the curved rigid pipe 4, and the middle vertical section of the curved rigid pipe 4 is fixed relative to the left end of the side support and guide mechanism.

[0035] It should be noted that the liquid naphthalene conveying and spraying mechanism relies on the power conveying pump 7 to provide conveying power when it is working. Therefore, it can quickly convey the liquid naphthalene inside the liquid naphthalene heat preservation tank 2 upward and spray it downward through the nozzle 6. The sprayed liquid naphthalene falls directly onto the naphthalene curing and cooling unit to achieve cooling, curing and adhering to its surface.

[0036] In any of the above embodiments, it is preferred that the side support and guide mechanism includes a horizontally arranged fixed frame 8, which is fixed above the ground 1 by ground connecting frames 9 installed at the bottom of its left and right ends. A lateral guide groove 10 is provided in the middle of the fixed frame 8, which is arranged through the front and back direction of the fixed frame 8. The translation control mechanism is installed on the right side of the lateral guide groove 10.

[0037] The two fixed frames 8 set at intervals on the front and rear sides are mainly used to support and guide the two ends of the naphthalene curing and cooling unit, so as to ensure the smoothness and stability of the naphthalene curing and cooling unit when it moves left and right.

[0038] In any of the above embodiments, preferably, the translation control mechanism includes translation racks 11 respectively fitted and installed in the two lateral guide slots 10. The left end of each translation rack 11 is fixedly connected to the naphthalene curing and cooling unit, and the right end of each translation rack 11 movably passes through the opening 12 at the right end of the corresponding fixed frame 8 and extends to its exterior. A gear mounting cavity 13 communicating with the interior of the lateral guide slot 10 is provided on the fixed frame 8 corresponding to the upper right side of each translation rack 11. A transmission gear 14 is respectively installed inside each gear mounting cavity 13. Both ends of the gear shaft 15 of the 14 extend movably to the front and rear sides of the fixed frame 8. The gear shafts 15 of the two transmission gears 14 are connected by a transmission shaft 16. The bottom of each transmission gear 14 meshes with the teeth on the top of the translation rack 11 below it. The two transmission gears 14 rotate together through a fixed axis to drive the translation rack 11 meshing with them to move synchronously in the left and right directions. A drive motor 17 is fixedly installed on the outer wall of the fixed frame 8 on the rear side. The motor shaft of the drive motor 17 is fixedly connected to the outer end of the gear shaft 15 of the transmission gear 14 at the current position.

[0039] It should be noted that the translation control mechanism relies on the drive motor 17 as the drive unit when it is working. When the drive motor 17 is working, it can drive the two transmission gears 14 to rotate on a fixed axis. When the two transmission gears 14 rotate synchronously on a fixed axis, they can synchronously drive the translation rack 11 meshing with it to move horizontally in the left and right direction. During the movement, the movement of the translation rack 11 can drive the sliding locking seats 18 at both ends of the entire naphthalene curing and cooling unit to move stably in the horizontal direction along the lateral guide groove 10. Controlling the forward and reverse rotation of the drive motor 17 can control the naphthalene curing and cooling unit to move back and forth in the left and right directions.

[0040] In any of the above embodiments, preferably, the naphthalene curing and cooling unit includes two symmetrically arranged sliding locking seats 18 that are respectively engaged and locked in the lateral guide grooves 10 at corresponding positions. The right end of each sliding locking seat 18 is fixedly connected to the left end of the translation rack 11 at its corresponding position. A cooling metal roller 19 is arranged horizontally in the front-rear direction between the two sliding locking seats 18. The interior of the cooling metal roller 19 is provided with a cooling chamber 20 for storing low-temperature coolant. The front end of the cooling chamber 20 is sealed, and an end cap 21 is sealed at the rear opening 12 of the cooling chamber 20. A central connecting front shaft 22 is fixedly installed at the center of the front end of the cooling metal roller 19. The front end of the central connecting front shaft 22 moves through the shaft hole on the corresponding sliding bracket 18 and extends to the front side of the sliding bracket 18, connecting with the servo motor 23 fixed on its front end face. A central material tube 24 is fixedly installed at the rear center of the end cap 21. The interior of the central material tube 24 is connected to the interior of the cooling chamber 20 of the cooling metal roller 19. The rear end of the central material tube 24 moves out through the shaft hole on the corresponding sliding bracket 18 and extends to the rear side of the sliding bracket 18. A control valve 25 is provided at the rear end of the central material tube 24. The rear end of the central material tube 24 is the inlet / outlet end and is used to connect to external pipelines when changing the coolant. When it is necessary to change the coolant into the cooling chamber 20, the control valve 25 is opened.

[0041] It should be noted that when the naphthalene curing and cooling unit is working, the rotation of the servo motor 23 can drive the entire cooling metal drum 19 to rotate at a low speed. During the rotation of the cooling metal drum 19, liquid naphthalene will be continuously sprayed and fallen from above. When the naphthalene lands on the surface of the cooling metal drum 19 with a lower temperature, it can be quickly cooled and solidified. In addition, since the cooling metal drum 19 is in a rotating state, the cooling speed can be accelerated to achieve further rapid cooling and solidification.

[0042] As the cooling time increases, the amount of solidified naphthalene that solidifies and adheres to the surface of the cooling metal roller 19 will increase. When a certain amount is reached, the translation control mechanism can be controlled to operate and the entire naphthalene solidification and cooling unit can be controlled to continuously move to the right under the sliding action of the sliding locking seats 18 on its front and rear sides and stop moving after being placed above the solid naphthalene scraping mechanism. The solid naphthalene scraping mechanism can be controlled to work to achieve rapid scraping.

[0043] Example 2: Compared with Example 1, this example also includes the following technical features:

[0044] The solid naphthalene scraping mechanism includes positioning frames 29 on the top of the two fixed frames 8 on the right side of the cooling metal drum 19. Two inclined connecting seats 26 are respectively arranged at intervals and symmetrically between the two positioning frames 29. Several inclined synchronous telescopic cylinders 27 are fixed at intervals along the front-back direction on the lower inclined surface of each inclined connecting seat 26. The bottom of the piston rod of each synchronous telescopic cylinder 27 is fixed to the top of a scraping cutter 28. Both scraping cutters 28 are arranged along the front-back direction. The bottom blade of the scraping cutter 28 is used to abut against the outer wall of the fixed-axis rotating cooling metal drum 19 in the working state and scrape the solid naphthalene generated by cooling and solidification on the outer wall downward. The scraped solid naphthalene falls into the solid naphthalene collection tank 3 below it.

[0045] It should be noted that when the solid naphthalene scraping mechanism is working, according to the thickness of the solid naphthalene adhering to the surface of the cooling metal roller 19, each synchronous telescopic cylinder 27 is controlled to extend downwards by different lengths, thereby driving the bottom of the scraping blade 28 to approach and continuously feed into the interior of the solid naphthalene layer. Thus, as the cooling metal roller 19 rotates continuously, rapid scraping is achieved until the scraping is completed. During the scraping process, the scraped naphthalene fragments will continuously fall into the solid naphthalene collection tank 3 for collection and await subsequent transfer.

[0046] In any of the above embodiments, it is preferred that the wall thickness of the cooling metal roller 19 is 3mm-5mm. Setting a suitable wall thickness for the cooling metal roller 19 can ensure its efficiency in conducting low temperatures outward and improve the cooling effect.

[0047] In any of the above embodiments, it is preferred that the cooling metal roller 19 is made of aluminum alloy or stainless steel to improve its conduction efficiency.

[0048] In any of the above embodiments, it is preferred that the cooling metal roller 19 is arranged in the front-to-back direction and placed in the space between the two fixed frames 8.

[0049] Specific working principle: When this equipment is working, the liquid refined naphthalene conveying and spraying mechanism continuously pumps the liquid refined naphthalene in the liquid refined naphthalene heat preservation tank 2 upward and sprays it downward as needed.

[0050] The sprayed liquid naphthalene falls onto the surface of the low-temperature naphthalene curing and cooling unit, allowing it to cool and solidify. To ensure effective cooling, the naphthalene curing and cooling unit can be controlled to rotate at an appropriate speed along a fixed axis. The combined effect of internal coolant heat conduction and rotary air cooling accelerates the adhesion and solidification of the liquid naphthalene on the surface of the unit. After a set cooling time, a suitable amount of solidified naphthalene is ensured to solidify on the surface. The translation control mechanism moves the naphthalene curing and cooling unit to the right along the side support guide mechanisms on both sides. The movement stops when the solid naphthalene scraping mechanism is lowered. At this point, the solid naphthalene scraping mechanism is activated, causing the corresponding scraper 28 to move down to a position close to or abutting the surface of the solid naphthalene scraping mechanism. As the fixed-axis rotation of the solid naphthalene scraping mechanism causes the solid naphthalene adhering to the surface of the cooling metal roller 19 of the solid naphthalene scraping mechanism to continuously detach from the surface of the cooling metal roller 19 under the scraping action of the scraping blade 28, and then fall into the solid naphthalene collection tank 3. After the scraping is completed, the naphthalene curing and cooling unit is controlled to return to the left, and then the above steps are repeated. In this way, the liquid naphthalene in the liquid naphthalene heat preservation tank 2 is continuously cooled, cured and collected.

[0051] In summary, this liquid naphthalene curing equipment uses a pump-driven spray cooling method to lift and spray the liquid naphthalene downwards. After spraying, the naphthalene falls directly into the naphthalene curing and cooling unit for low-temperature cooling and solidification. After solidification, the naphthalene is positioned by a translation control mechanism, and finally, a solid naphthalene scraping mechanism scrapes off the solid liquid adhering to the surface of the naphthalene curing and cooling unit for rapid collection, avoiding direct contact between water and liquid naphthalene and effectively ensuring the purity of the naphthalene. Specifically, the liquid naphthalene curing equipment can collect the liquid naphthalene that falls back from the top through the liquid naphthalene insulation tank 2, effectively reducing the splashing and waste of liquid naphthalene, enabling repeated spray cooling of liquid naphthalene, and improving the efficient curing and recovery of liquid naphthalene. In addition, when collecting the cured refined naphthalene, two scraping blades 28 on the solid refined naphthalene scraping mechanism are used to scrape the material, which effectively improves the scraping efficiency. At the same time, the scraping efficiency is controlled by controlling the rotation speed of the cooling metal roller 19 of the refined naphthalene curing and cooling unit. When the solid refined naphthalene scraping mechanism scrapes the material, the feed amount of each synchronous telescopic cylinder 27 can be controlled according to the thickness of the material to be scraped each time, which effectively ensures the scraping effect.
