Description

Technical Field

[0001] The utility model relates to the technical field of chemical storage tanks, and more specifically to a rubber antioxidant chemical storage tank. Background Art

[0002] By adding rubber antioxidants, the heat resistance, oil resistance, wear resistance, ozone resistance and other properties of rubber products can be significantly improved, thereby extending their service life. Most of the existing rubber antioxidants are liquids, and the liquid rubber antioxidants mainly include amines, phenols, heterocyclics and the like. Most of them are stored in storage tanks. When most of the existing storage tanks store rubber antioxidants, because the rubber antioxidants have a certain viscosity, when the rubber antioxidants are discharged, the rubber antioxidants are easy to remain on the inner wall of the storage tank. When used next time, the residual antioxidant may react with the newly added antioxidant. In order to clean the residual rubber antioxidant on the inner wall, most of them use the driving device in the storage tank to drive the annular scraper to clean the inner wall of the storage tank.

[0003] Because the annular scraper moves along the inner wall of the storage tank, it will produce a certain amount of friction, which will cause the annular scraper to be worn to a certain extent. After a long time, a gap will be formed between the annular scraper and the inner wall of the storage tank, resulting in a decrease in the cleaning effect. In order to maintain the cleaning effect, the annular scraper needs to be replaced regularly. However, most of the existing annular scrapers are connected to the driving device set in the storage tank by bolts, which requires the staff to use auxiliary tools to turn the bolts, making this replacement method cumbersome.

The annular scraper 3 is slidably matched with the inner wall of the tank body 1, and a driving assembly 9 driving the reciprocating assembly 6 to rotate is provided on the tank cover 2.

[0022] In this embodiment, the feed pipe 5 is connected to a pipeline for conveying the antioxidant, so that the antioxidant enters the tank body 1 through the feed pipe 5 and is stored in the tank body 1. When the antioxidant needs to be taken out from the tank body 1, the discharge pipe 4 is connected to a pipeline, so that the antioxidant in the tank body 1 is taken out through the discharge pipe 4. Valves are provided on the discharge pipe 4 and the feed pipe 5. When the feed pipe 5 feeds or the discharge pipe 4 discharges, the corresponding valve is opened manually, and the valve is closed at other times. When the discharge pipe 4 is finished discharging, the antioxidant will remain on the inner wall of the tank body 1. At this time, the drive assembly 9 is started, and the drive assembly 9 drives the reciprocating assembly 6 to work, so that the moving assembly 7 moves along the reciprocating assembly 6, and drives the connecting assembly 8 to move. The connecting assembly 8 synchronously drives the annular scraper 3 to move up and down along the inner wall of the tank body 1, and the antioxidant on the inner wall of the tank body 1 is scraped by the annular scraper 3, so that the scraped antioxidant flows to the bottom of the tank body 1 and flows out from the discharge pipe 4. When the annular scraper 3 needs to be replaced, the staff unfastens the bolt connection between the tank body 1 and the tank cover 2, and the staff lifts the tank cover 2 through the lifting equipment, and the tank cover 2 drives the driving assembly 9 to move synchronously. At this time, the staff removes the annular scraper 3 connected to the connecting assembly 8 from the connecting assembly 8, and connects the new annular scraper 3 to the connecting assembly 8, and then the staff bolts the tank body 1 to the tank cover 2, and the driving assembly 9 is connected to the reciprocating assembly 6.

[0023] Specifically, the driving assembly 9 includes a motor 901, a support rod 902 and a rectangular block 903. The motor 901 is fixedly mounted on the top of the tank cover 2, one end of the support rod 902 is fixedly connected to the output end of the motor 901, and the other end passes through the tank cover 2 and is rotatably connected to the tank cover 2.

The reciprocating assembly 6 includes a connecting rod 601, a rectangular groove 602, a reciprocating screw rod 603 and a rotating rod 604. One end of the rotating rod 604 is rotatably connected to the bottom of the tank body 1, and one end of the reciprocating screw rod 603 is fixedly connected to the other end of the rotating rod 604. One end of the connecting rod 601 is fixedly connected to the other end of the reciprocating screw rod 603. The rectangular groove 602 is provided on the other end of the connecting rod 601, and the rectangular block 903 cooperates with the rectangular groove 602.

[0024] In this embodiment, when it is necessary to clean the antioxidant remaining on the inner wall of the tank body 1, the rectangular block 903 is located in the rectangular groove 602 in the initial state. At this time, the motor 901 is started, the motor 901 drives the support rod 902 to rotate, the support rod 902 drives the rectangular block 903 to rotate, the rectangular block 903 drives the connecting rod 601 to rotate, the connecting rod 601 drives the reciprocating screw rod 603 to rotate, and the reciprocating screw rod 603 drives the rotating rod 604 to rotate. When it is necessary to replace the annular scraper 3, the tank cover 2 is lifted horizontally by the lifting device, and at this time, the tank cover 2 drives the motor 901, the support rod 902 and the rectangular block 903 to move synchronously, so that the rectangular block 903 moves along the inner wall of the rectangular groove 602 and disengages from the rectangular groove 602. When the annular scraper 3 is replaced, the tank cover 2 is put back to the initial state by the lifting device, the rectangular block 903 enters the rectangular groove 602, the tank body 1 is bolted to the tank cover 2, and the tank body 1 is sealed by the tank cover 2.

[0025] Specifically, the moving assembly 7 includes a limiting rod 701 and a slider 702 . One end of the limiting rod 701 is fixedly connected to the bottom of the tank body 1 . The slider 702 is sleeved on the limiting rod 701 and the reciprocating screw 603 . The slider 702 is threadedly connected to the reciprocating screw 603 .

[0026] In this embodiment, when the reciprocating screw rod 603 rotates, the slider 702 will reciprocate along the limiting rod 701 due to the limiting of the limiting rod 701 .

[0027] Specifically, the connecting components 8 each include two fixed boxes 801, two springs 802, two fixed blocks 803, two fixed holes 804 and two connecting blocks 805. The two fixed boxes 801 are symmetrically arranged, one side of the two fixed boxes 801 is respectively fixedly connected to the two sides of the slider 702, and the other side of the two fixed boxes 801 is open. The two springs 802 are respectively arranged in the corresponding fixed boxes 801, and one end of the two springs 802 is respectively fixedly connected to the inner wall of the corresponding fixed box 801. The two fixed blocks 803 are respectively slidably arranged in the corresponding fixed boxes 801 and fixedly connected to the other end of the corresponding spring 802.

The two connecting blocks 805 are fixedly connected to the annular scraper 3, and the two connecting blocks 805 are respectively slidably matched with the corresponding fixing holes 804.

[0028] In this embodiment, in the initial state, the two connecting blocks 805 are respectively located in the two fixing holes 804, and the fixing block 803 is against the annular scraper 3. When the slider 702 moves, it drives the fixing box 801, the spring 802, the fixing block 803, the connecting block 805 and the annular scraper 3 to move synchronously. The annular scraper 3 is moved back and forth along the inner wall of the tank body 1. The anti-aging agent on the inner wall of the tank body 1 is scraped by the annular scraper 3, so that the anti-aging agent flows to the bottom of the tank body 1. The cleaning of the anti-aging agent on the inner wall of the tank body 1 is completed, when the annular scraper 3 needs to be replaced. The tank cover 2 is lifted, and the staff enters the tank body 1 at this time. The staff pushes the two fixing blocks 803, and the fixing blocks 803 move along the inner wall of the fixing box 801 and squeeze the spring 802. At this time, the two connecting blocks 805 are separated from the fixing holes 804. The fixing block 803 is no longer against the annular scraper 3, and the connecting block 805 is no longer connected to the fixing block 803 through the fixing hole 804. The staff takes out the annular scraper 3 from the top of the tank body 1, and the annular scraper 3 drives the two connecting blocks 805 to move synchronously. At this time, the staff puts the new annular scraper 3 horizontally into the tank body 1, and the annular scraper 3 slides along the inner wall of the tank body 1, so that the two connecting blocks 805 are at the same level as the two fixing holes 804. At this time, the staff no longer pulls the fixing block 803. The spring 802 rebounds, driving the fixing block 803 to move, so that the two connecting blocks 805 enter the corresponding fixing holes 804, and the fixing block 803 abuts against the annular scraper 3. At this time, the replacement of the annular scraper 3 is completed.

[0029] Specifically, the two fixing blocks 803 are both fixedly mounted with a pull plate 10 , and the two pull plates 10 are symmetrically arranged.

[0030] In this embodiment, the fixing block 803 is more conveniently pushed by the pulling plate 10 .
