Description

Technical Field

[0001] The invention relates to the technical field of concrete foaming agent storage, in particular to a foam concrete foaming agent storage device. Background Art

[0002] Foamed concrete is made by mechanically foaming the foaming agent through the foaming system of the foaming machine and evenly mixing the foam with cement slurry. Ensuring that the foaming agent remains in the best condition during storage is not only related to the smooth progress of the foamed concrete production process, but also directly affects the quality and performance of the final product.

[0003] After the foaming agent is discharged from the storage tank, the residual foaming agent in the tank can be cleaned up to facilitate the storage of subsequent foaming agents. Chinese patent publication number "CN221738833U" discloses a foaming agent storage device, which mainly adds a rotatable mounting frame, a connecting frame and a scraping block to the tank, and the residual foaming agent in the tank is scraped off by rotating the mounting frame, the connecting frame and the scraping block. Although this type of structure can scrape off the residual foaming agent in the tank, the scraped foaming agent is also easy to adhere to the structural corners of the mounting frame, the connecting frame and the scraping block. At the same time, such components are arranged inside the tank, which makes it very difficult to clean. In addition, the components arranged inside the tank will also occupy the internal storage space of the tank, resulting in a reduction in the effective storage capacity of the tank.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Embodiment 1:

[0033] Reference Figure 1 , a foam concrete foaming agent storage device, comprising:

[0034] Base 1, used to provide a supporting foundation for the entire device structure;

[0035] The upper tank assembly is used to provide storage space for the concrete foaming agent. The upper tank assembly includes a plurality of bottomed tank bodies 5 and a lifting mechanism. The lifting mechanism is used to lift the bottomed tank bodies 5. A feed pipe 13 communicating with the interior of the bottomed tank bodies 5 is installed at the upper end thereof. A discharge pipe 14 communicating with the interior of the bottomed tank bodies 5 is installed on the side wall thereof. Valves are installed in the feed pipe 13 and the discharge pipe 14.

[0036] A lower bottom assembly is used to provide a bottom seal for the bottomless tank body 5 and to form a sealed tank with the bottomless tank body 5. The lower bottom assembly includes a plurality of tank bottoms 4 and a rotating mechanism. The rotating mechanism is used to drive the tank bottom 4 to rotate around the center of the base 1;

[0037] And the lifting mechanism is connected with the rotating mechanism through the connecting mechanism.

[0038] In this embodiment, when storing the concrete foaming agent, the valve in the feed pipe 13 can be opened, and the concrete foaming agent can be input into the bottomed tank body 5 through the feed pipe 13. At this time, the tank bottom 4 and the bottomed tank body 5 form a complete sealed tank, so that the concrete foaming agent can be stored. When the foaming agent needs to be released, the valve in the discharge pipe 14 can be opened, and the foaming agent can be released from the discharge pipe 14.

[0039] When the foaming agent in the entire tank body is released and the inside of the tank body needs to be cleaned, the lifting mechanism can be controlled to lift the bottomed tank body 5, and then the connecting mechanism drives the rotating mechanism to operate. The rotating mechanism can drive the tank bottom 4 to rotate a certain angle around the center of the base 1, so that the bottomed tank body 5 can be separated from the tank bottom 4. The staff can use a high-pressure water gun to rinse the upper end surface of the tank bottom 4 and the inner wall of the bottomed tank body 5. In this way, there is no need to install a related cleaning mechanism inside the tank body, and the residual foaming agent inside the tank body can be cleaned, so no adhesion residue will be generated, and it will not occupy the effective storage space in the tank body, thereby improving the storage capacity of the tank body for the concrete foaming agent.

[0040] Embodiment 2:

[0041] Furthermore, compared with the first embodiment, the lifting mechanism, connecting mechanism and rotating mechanism in this embodiment are as follows:

[0042] The lifting mechanism includes a cantilever 7, a hydraulic lifting cylinder 11, a suspension rod 12, and a plurality of connecting rods 9. The cantilever 7 is fixedly connected to the upper end of the base 1. The fixing seat of the hydraulic lifting cylinder 11 is fixedly installed on the lower side wall of the cantilever 7. One end of each connecting rod 9 is fixedly connected to the side wall of the connected bottomless tank 5. The other end of each connecting rod 9 is fixedly connected to the side wall of the suspension rod 12. The telescopic end of the hydraulic lifting cylinder 11 is fixedly connected to the upper end of the suspension rod. Specifically, Figure 1 As shown, the cantilever 7 is an "L" structured arm, the base portion of the hydraulic lift cylinder 11 is installed on the lower side of the transverse portion of the cantilever 7, the telescopic end of the hydraulic lift cylinder 11 is located on the lower side and is connected to the suspension rod 12, thereby driving the suspension rod 12 to rise and fall.

[0043] The rotating mechanism includes a rotating seat 2 and a plurality of connecting plates 3. The rotating seat 2 is rotatably arranged on the upper end of the base 1. One end of each connecting plate 3 is fixedly connected to the side wall of the rotating seat 2, and the other end of each connecting plate 3 is fixedly connected to the side wall of the adjacent tank bottom 4.

[0044] The connecting mechanism includes a mechanism box 10, a rack 18, a lifting rod 19, a first rotating shaft 25, a first gear 20, a first active bevel gear 17, a first driven bevel gear 16 and a hollow shaft 6. The first rotating shaft 25 is rotatably set on the inner wall of the mechanism box 10, and the rack 18 is slidably set in the mechanism box 10. One end of the lifting rod 19 is fixedly connected to the upper end of the rack 18, and the other end of the lifting rod 19 is fixedly connected to the side wall of the adjacent connecting rod 9. The first active bevel gear 17 and the first gear 20 are respectively fixedly connected to the two ends of the first rotating shaft 25, the first driven bevel gear 16 is fixedly connected to the hollow shaft 6, and the first driven bevel gear 16 is meshed with the first active bevel gear 17. The lower end of the hollow shaft 6 is fixedly connected to the rotating seat 2, and the mechanism box 10 is fixedly connected to the side wall of the cantilever 7 through a plurality of fixing rods 8.

[0045] Reference Figure 1 and Figure 4 A first limiting hole 32 is formed at the upper end of the connecting plate 3 , and a first limiting rod 26 is inserted into the first limiting hole 32 . The upper end of the first limiting rod 26 is fixedly connected to the side wall of the adjacent connecting rod 9 .

[0046] Reference Figure 5 A second limiting hole 33 is provided at the upper end of the base 1, a second limiting rod 31 is inserted into the second limiting hole 33, a mechanism slot 34 is provided at the center of the base 1, a moving mechanism for moving the second limiting rod 31 is installed in the mechanism slot 34. The moving mechanism includes a screw rod 28 rotatably connected to the mechanism slot 34, a nut 29 is threadedly connected to the screw rod 28, and the nut 29 is fixedly connected to the second limiting rod 31 through a connecting rod 30. Specifically, one end of the connecting rod 30 is fixedly set on the side wall of the nut 39, and the other end of the connecting rod 30 is fixedly set on the side wall of the second limiting rod 31. The second limiting rod 31 can slide up and down along the second limiting hole 33. When the screw rod 28 rotates, the nut 29 can be raised and lowered through threaded transmission, thereby driving the second limiting rod 31 to move up and down;

[0047] Furthermore, the second limiting rod 31 and the connecting rod 30 can also limit the nut 29, so that when the screw rod 28 rotates, the nut 29 cannot be driven to rotate together, and the nut 29 can only move up and down under the action of the thread.

[0048] A rotating rod 27 is rotatably provided in the hollow shaft 6, the lower end of the rotating rod 27 is fixedly connected to the upper end of the screw 28, the upper end of the rotating rod 27 is rotatably connected to the second driven bevel gear 21, and a second rotating shaft 24 is rotatably connected in the mechanism box 10, and the two ends of the second rotating shaft 24 are respectively fixedly connected to the second active bevel gear 22 and the second gear 23, and the second driven bevel gear 21 is meshed with the second active bevel gear 22.

[0049] In this embodiment, Figure 1 and Figure 2 As shown, at the beginning, the first limiting rod 26 is inserted into the first limiting hole 32, at which time the connecting plate 3 and the rotating seat 2 can be limited, and the rotating seat 2 cannot rotate, so the position of each tank bottom 4 can remain unchanged, and thus can be stably combined with the bottomed tank body 5 to form a complete sealed tank, which can store the foaming agent.

[0050] When cleaning is needed, the hydraulic lifting cylinder 11 on the cantilever 7 can pull the suspension rod 12 up, and the suspension rod 12 can drive each connecting rod 9 to rise. Then the connecting rod 9 will drive the first limiting rod 26 to rise and disengage from the first limiting hole 32, and the limit on the rotating seat 2 will be released at this time.

[0051] When the connecting rod 9 rises, it will also drive each bottomed tank body 5 to rise, so that each bottomed tank body 5 gradually separates from the tank bottom 4 at the lower side;

[0052] Reference Figure 2 and Figure 3 When the connecting rod 9 rises, it will also drive the rack 18 to move upward through the lifting rod 19. When the first limiting rod 26 is disengaged from the first limiting hole 32 and the bottomed tank body 5 is disengaged from the tank bottom 4, as the connecting rod 9 continues to rise, the rack 18 will begin to mesh with the first gear 20, and at this time, it will gradually drive the first gear 20 to rotate. The first gear 20 drives the first driven bevel gear 16 to rotate through the first rotating shaft 25 and the first active bevel gear 17. The first driven bevel gear 16 will drive the rotating seat 2 to rotate through the hollow shaft 6. The rotating seat 2 drives the corresponding tank bottom 4 to rotate around the center of the base 1 by a certain angle through each connecting plate 3, so that the tank bottom 4 and the bottomed tank body 5 are completely staggered, so as to facilitate the washing of the tank bottom 4 and the bottomed tank body 5 respectively;

[0053] Then the connecting rod 9 continues to drive the rack 18 to rise through the lifting rod 19, and the rack 18 will be separated from the first gear 20. Therefore, the first gear 20 stops rotating at this time, and correspondingly, the rotating seat 2, the connecting plate 3 and the tank bottom 4 also stop rotating immediately; and when the connecting plate 3 stops rotating after rotating a certain angle, the first limiting hole 32 on the connecting plate 3 will be located directly above the second limiting hole 33.

[0054] Then the rack 18 continues to be driven upward, and the rack 18 gradually begins to mesh with the second gear 23, so that the second gear 23 can be driven to rotate, and the second driven bevel gear 21 can be driven to rotate through the second rotating shaft 24 and the second active bevel gear 22, thereby driving the rotating rod 27 to rotate. Figure 5 When the rotating rod 27 rotates, it will drive the screw rod 28 in the mechanism groove 34 to rotate, so that the nut 29 can move up, and the nut 29 will also drive the second limiting rod 31 to move up synchronously through the connecting rod 30. When the second limiting rod 31 moves up, it passes through the second limiting hole 33 and enters the first limiting hole 32. At this time, the second limiting rod 31 can be connected to the connecting plate 3, so that the connecting plate 3 and the rotating seat 2 cannot rotate freely. In this way, the rotating seat 2 is locked, and the position of each tank bottom 4 will remain unchanged, which can prevent the tank bottom 4 from rotating freely during the washing process and cause harm to the staff.

[0055] After the cleaning is completed, the hydraulic lifting cylinder 11 drives the suspension rod 12 to move downward, so that the connecting rod 9 and the bottom-removing tank body 5 can be moved downward synchronously:

[0056] As for the mechanism box 10, the rack 18 is also driven to move downward, and the rack 18 will first mesh with the second gear 23 and drive the second gear 23 to rotate in the opposite direction. Then, under the transmission action of each component, the rotating rod 27 is driven to rotate in the opposite direction, and finally the screw rod 28 is reversed, and the nut 29 moves downward. The nut 29 drives the second limiting rod 31 to move downward through the connecting rod 30, and the second limiting rod 31 will disengage from the first limiting hole 32 and retract into the second limiting hole 33. At this time, the rotation limit of the connecting plate 3 and the rotating seat 2 can be released, and the rotating seat 2 can rotate freely at this time.

[0057] Then the rack 18 continues to move downward, and begins to mesh with the first gear 20 and drives the first gear 20 to rotate. Then, under the transmission action of the corresponding components, the hollow shaft 6 is driven to rotate. The hollow shaft 6 can drive the rotating seat 2 and the connecting plate 3 on the lower side to rotate to the initial position, thereby making each tank bottom 4 rotate to the initial position. When the tank bottom 4 rotates to the initial position, the rack 18 immediately disengages from the first gear 20.

[0058] As the connecting rod 9 continues to move downward, the first limiting rod 26 on the lower side of the connecting rod 9 can be reinserted into the first limiting hole 32, and the connecting plate 3 and the rotating seat 2 can be limited and locked again, so that the position of the tank bottom 4 can remain unchanged. Then, the bottomed tank body 5 moves downward and forms a complete sealed tank with the tank bottom 4 again, and the concrete foaming agent can be stored again.

[0059] Compared with the first embodiment, this embodiment adds the above-mentioned specific structures of the lifting mechanism, the connecting mechanism and the rotating mechanism, so that the movement of the lifting mechanism and the movement of the rotating mechanism are coordinated, thereby avoiding interference between the movement of the bottomed tank body 5 and the tank bottom 4. At the same time, it can ensure that the bottomed tank body 5 and the tank bottom 4 are perfectly staggered and separated, so that the distance between the two is relatively large, which is convenient for the staff to use a high-pressure water gun for flushing.

[0060] Embodiment three:

[0061] like Figure 4 As shown, an annular sealing groove 15 is provided at the upper end of the tank bottom 4 .

[0062] In this embodiment, an annular sealing groove 15 is additionally provided on the tank bottom 4, so that when the bottom-removed tank body 5 falls on the tank bottom 4, the tank bottom 4 can be sealed with the attached sealing groove 15. Figure 6 The circumferential side wall of the bottomed tank body 5 can be inserted into the annular sealing groove 15. At this time, the circumferential side wall of the bottomed tank body 5 can fit tightly with the circumferential inner wall of the annular sealing groove 15, which can avoid the problem of poor sealing performance caused by the uneven surface of the tank bottom 4 after long-term use.

[0063] In addition, it should be noted that, according to the first and second embodiments, the movement of the bottomless tank body 5 and the movement of the tank bottom 4 are performed sequentially, so the annular sealing groove 15 does not hinder the movement of the two.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
