Description

Technical Field

[0001] This utility model relates to the field of densifier storage technology, and more specifically, to a concrete waterproof densifier storage tank. Background Technology

[0002] Concrete waterproofing and densifying agents (such as waterproofing agents, water-reducing agents, early-strength agents, and other powder additives) can effectively improve the gel density, compressive strength, crack resistance, and impermeability of concrete. Among them, powdered densifying agents are usually stored in tanks after production. However, these densifying agents are usually highly hygroscopic. If the tank is not properly sealed, allowing external moisture to seep in, the powder inside is very easy to absorb moisture and clump. The clumped densifying agent will form a stable "arch bridge" structure inside the tank, thereby blocking the discharge pipe and hindering normal material discharge.

[0003] To address this issue, existing technologies often involve installing vibration devices on the outer wall of the silo or tank to break up the arches. However, while this method can achieve a certain degree of arch breaking effect, the vibration energy is transmitted from the outer wall inwards, making it difficult to effectively reach the middle of the material, resulting in an unsatisfactory arch breaking effect. Furthermore, the agglomerated compacting agent tends to adhere to the inner wall of the tank, making it impossible to discharge and reducing the effective volume of the tank. Since the vibration energy is significantly attenuated during its transmission from the tank wall to the interior, it is greatly weakened by the time it reaches the inner wall surface. At the same time, the force generated by conventional vibration devices is mainly parallel to the tank wall, making it difficult to effectively overcome the adhesion between the agglomerated material and the tank wall. Therefore, existing vibration arch breaking devices are also unable to shake off these agglomerated materials adhering to the inner wall. Utility Model Content

[0004] The purpose of this utility model is to provide a concrete waterproofing and densifying agent storage tank to solve the problems mentioned in the background art.

[0005] The vibration energy of the vibrating device is transmitted from the outer wall to the inside, making it difficult to effectively reach the middle of the material, resulting in an unsatisfactory arch-breaking effect.

[0006] To address the above problems, this utility model aims to provide a concrete waterproofing densifier storage tank, comprising a tank body. A main shaft is coaxially rotatably mounted inside the tank body. Several connecting rods are horizontally fixed on both sides of the main shaft's circumferential sidewall, equidistantly distributed along the main shaft's axis. A vertical scraper is vertically fixed at the other end of each connecting rod, contacting the inner circumferential wall of the tank body. The ends of adjacent scrapers are at the same height. A driving mechanism is mounted on the upper end of the main shaft, rotatably penetrating the upper sidewall of the tank body. This driving mechanism drives the main shaft to reciprocate vertically and rotate around its own axis. When the driving mechanism drives the main shaft to reciprocate vertically and rotate, the main shaft drives the connecting rods to move synchronously, causing the connecting rods to break up the densifier inside the tank. When the driving mechanism only drives the main shaft to rotate around its own axis, the main shaft drives the vertical scraper to rotate via the connecting rods, causing the vertical scraper to scrape off the densifier adhering to the inner circumferential wall of the tank body.

[0007] As a further improvement to this technical solution, the driving mechanism includes a second motor fixedly mounted on the upper side wall of the tank via a bracket. An eccentric wheel is fixedly connected to the output shaft of the second motor via a spline. A sleeve frame is slidably fitted on the circumferential side wall of the eccentric wheel. The side wall of the sleeve frame is rotatably connected to the upper end of the main shaft.

[0008] As a further improvement to this technical solution, side ears are fixedly connected to both sides of the sleeve frame, and guide rods are vertically fixedly connected to the upper side wall of the tank body at positions corresponding to the two side ears, and the side ears are slidably sleeved on the corresponding guide rods.

[0009] As a further improvement to this technical solution, the drive mechanism also includes a first motor fixedly installed on the upper side wall of the tank, and a drive gear is coaxially and fixedly connected to the upper end of the output shaft of the first motor via a spline.

[0010] As a further improvement to this technical solution, a driven gear is coaxially and fixedly connected to the main shaft via a spline. When the drive mechanism drives the main shaft to move vertically back and forth, the driving gear and the driven gear remain engaged.

[0011] As a further improvement to this technical solution, a feed pipe is fixedly connected to the upper side wall of the tank, a discharge pipe is fixedly connected to the lower side wall of the tank, and a slide valve is fixedly installed at the other end of the discharge pipe.

[0012] As a further improvement to this technical solution, the tank body is composed of an upper cylindrical body and a lower conical body. An inclined scraper is fixedly connected to the upper end of the bottom vertical scraper. When the drive mechanism drives the main shaft to move to the lowest position, the inclined scraper contacts the conical inner wall of the conical body.

[0013] As a further improvement to this technical solution, a dust cover is fixedly installed on the upper side wall of the tank, and the drive mechanism is located inside the dust cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. In this concrete waterproofing densifier storage tank, when the output shaft of the second motor slowly rotates, driving the main shaft and connecting rod to move vertically back and forth synchronously, the connecting rod breaks the arch of the densifier inside the tank. At the same time, the output shaft of the first motor slowly rotates, driving the main shaft and connecting rod to rotate synchronously. The combination of the vertical reciprocating movement and rotation of the connecting rod enables several connecting rods to fully break the arch of the densifier inside the tank, effectively improving the arch-breaking effect.

[0016] 2. In this concrete waterproofing densifier storage tank, when the second motor drives the main shaft to move to the lowest position, the inclined scraper contacts the inner wall of the conical cylinder. At this time, the output shaft of the second motor stops rotating, and the first motor drives the vertical scraper and the inclined scraper to rotate together. The rotating vertical scraper can effectively scrape off the densifier adhering to the cylindrical inner wall of the tank, while the inclined scraper scrapes off the densifier adhering to the conical inner wall of the tank. This ensures that all the densifier inside the tank can be smoothly discharged through the discharge pipe, effectively avoiding the problem of reduced effective volume due to densifier adhering to the inner wall of the tank.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figures 1-3 As shown, the purpose of this embodiment is to provide a concrete waterproofing densifier storage tank, including a tank body 1. The tank body 1 is composed of an upper cylindrical body and a lower conical body. An inlet pipe 11 is fixedly connected to the upper side wall of the tank body 1, and an outlet pipe 12 is fixedly connected to the lower side wall of the tank body 1. Both the inlet pipe 11 and the outlet pipe 12 are connected to the interior of the tank body 1. The connection between the outlet pipe 12 and the tank body 1 is located at the bottom end of the conical body. A normally closed gate valve is fixedly installed at the other end of the outlet pipe 12. When powdered concrete waterproofing densifier is injected into the tank body 1 for storage through the inlet pipe 11, the closed gate valve blocks the outlet pipe 12 to prevent the densifier inside the tank body 1 from leaking through the outlet pipe 12, thereby storing the densifier inside the tank body 1. When it is necessary to take out the densifier inside the tank body 1, the gate valve is opened to allow the densifier inside the tank body 1 to be discharged through the outlet pipe 12.

[0031] If the sealing of tank 1 is defective, the powdered densifier inside it is prone to absorbing moisture and clumping. The clumped densifier will form a stable arch bridge structure inside tank 1, causing the powder to be unable to be discharged normally through the discharge pipe 12. At the same time, the clumped sealant is also prone to adhering to the inner wall of tank 1, which not only prevents discharge but also reduces the effective volume of tank 1.

[0032] To solve the above problems, a main shaft 3 is coaxially rotatable inside the tank 1, as shown in the reference. Figure 5Several connecting rods 31 are horizontally fixed on both sides of the circumferential sidewall of the main shaft 3. These connecting rods 31 are equidistantly distributed along the axis of the main shaft 3. A vertical scraper 32 is vertically fixed at the other end of the connecting rod 31. The vertical scraper 32 contacts the inner circumferential wall of the tank 1. The ends of two adjacent vertical scrapers 32 are at the same height. An inclined scraper 33 is fixedly connected to the upper end of the lowest vertical scraper 32. The upper end of the main shaft 3 rotates through the upper sidewall of the tank 1 and is equipped with a drive mechanism 4. The drive mechanism 4 is used to drive the main shaft 3 to move vertically back and forth and rotate around its own axis.

[0033] When the drive mechanism 4 drives the main shaft 3 to move and rotate vertically, the main shaft 3 drives several connecting rods 31 to move synchronously. The moving connecting rods 31 cut off and break the arched structure formed by the densifying agent inside the tank 1, so that the connecting rods 31 can break the arch of the densifying agent inside the tank 1, and the densifying agent can be discharged through the discharge pipe 12 better.

[0034] The structure of drive mechanism 4 is described in detail below, referring to... Figure 4 The drive mechanism 4 includes a second motor 44 fixedly mounted on the upper side wall of the tank 1 via a bracket. An eccentric wheel 45 is fixedly connected to the output shaft of the second motor 44 via a spline. A sleeve 46 is slidably fitted onto the circumferential side wall of the eccentric wheel 45. The side wall of the sleeve 46 is rotatably connected to the upper end of the main shaft 3. (See reference...) Figure 6 Both sides of the sleeve frame 46 are fixedly connected with side ears 47. The upper side wall of the tank body 1 is vertically fixedly connected with guide rods 48 at the positions corresponding to the two side ears 47. The side ears 47 are slidably sleeved on the corresponding guide rods 48. The side ears 47 and guide rods 48 cooperate to constrain the sleeve frame 46 to move only vertically. The drive mechanism 4 also includes a first motor 41 fixedly installed on the upper side wall of the tank body 1. The upper end of the output shaft of the first motor 41 is coaxially fixedly connected with a drive gear 42 via a spline. The main shaft 3 is coaxially fixedly connected with a driven gear 43 via a spline. The driven gear 43 is a wide-tooth gear.

[0035] It should be noted that when the main shaft 3 drives the driven gear 43 to move vertically back and forth, the driving gear 42 moves relative to the driven gear 43. During this process, the length of the moving path of the driving gear 42 is less than the width of the driven gear 43. Therefore, when the drive mechanism 4 drives the main shaft 3 to move vertically back and forth, the driving gear 42 and the driven gear 43 always remain in a meshed state.

[0036] When the second motor 44 starts, its output shaft drives the eccentric wheel 45 to rotate slowly. The eccentric wheel 45 pushes the sleeve 46 to move vertically back and forth under the guidance of the guide rod 48. The moving sleeve 46 drives the main shaft 3 and the connecting rod 31 to move synchronously, so that the connecting rod 31 breaks the arch of the densifying agent inside the tank 1. At the same time, the moving connecting rod 31 drives the driven gear 43 to move synchronously. Since the length of the movement path of the driving gear 42 is less than the width of the driven gear 43, the driven gear 43 always keeps meshed with the driving gear 42 during the movement. In this state, the first motor 41 starts, and its output shaft drives the driving gear 42 to rotate slowly. The driving gear 42 drives the driven gear 43 that meshes with it, so that the driven gear 43, the main shaft 3 and the connecting rod 31 rotate synchronously.

[0037] The vertical reciprocating movement of the connecting rod 31 mainly serves the following functions: it inserts deep into the compactor, destroying the vertically formed arched structure (central arch), and agitates the compactor during its up-and-down movement. Its rotation causes the connecting rod 31 to continuously change its position on the horizontal plane, effectively destroying the annular arches formed at the edge of the tank 1 or at different radii, and scraping the tank 1 to prevent the compactor from adhering. The combination of vertical reciprocating movement and rotation makes the movement trajectory of the connecting rod 31 form a three-dimensional coverage within the space of the tank 1. Therefore, the combination of vertical reciprocating movement and rotation of the connecting rod 31 enables several connecting rods 31 to achieve comprehensive arch breaking of the compactor inside the tank 1, effectively improving the arch breaking effect.

[0038] Both the first motor 41 and the second motor 44 are low-speed motors, and their output shafts can rotate at a low speed (the first motor 41 rotates at 10 revolutions per minute, and the second motor 44 rotates at 5 revolutions per minute). By having the first motor 41 drive the connecting rod 31 to rotate slowly, and the second motor 44 drive the connecting rod 31 to move vertically back and forth slowly, it is possible to avoid the connection between the connecting rod 31 and the main shaft 3 breaking due to excessive resistance when the connecting rod 31 agitates the powdered compactor. This is because if the connecting rod 31 moves too fast, it will violently squeeze and displace the surrounding powdered compactor, encountering extremely high resistance instantly and forming an impact load. This impact force will generate stress at the connection between the connecting rod 31 and the main shaft 3 (usually a stress concentration point) that is far higher than the material's bearing limit, thus leading to breakage. Maintaining a slow movement speed can significantly reduce the peak resistance and impact effect, ensuring the normal use of the connecting rod 31.

[0039] After breaking up the compaction agent, the second motor 44 drives the main shaft 3 to its lowest position. This action causes the connecting rod 31, vertical scraper 32, and inclined scraper 33 to move downwards synchronously until the inclined scraper 33 contacts the inner wall of the conical cylinder. At this point, the output shaft of the second motor 44 stops rotating, while the first motor 41 continues to drive the main shaft 3 to rotate around its own axis. The main shaft 3 drives the vertical scraper 32 to rotate via the connecting rod 31, and the vertical scraper 32 drives the inclined scraper 33 to rotate together. Since two adjacent vertical scrapers 32... With their ends close together at the same height, the working surfaces of all the vertical scrapers 32 together form a continuous cylindrical side. This allows the rotating vertical scrapers 32 to effectively scrape off the densifying agent adhering to the cylindrical inner wall of the tank 1, while the oblique scraper 33 is responsible for scraping off the densifying agent adhering to the conical inner wall of the tank 1. This process ensures that all the densifying agent inside the tank 1 can be smoothly discharged through the discharge pipe 12, effectively avoiding the problem of densifying agent adhering to the inner wall of the tank 1 and causing its effective volume to decrease.

[0040] A dust cover 2 is fixedly installed on the upper side wall of the tank body 1. The drive mechanism 4 is located inside the dust cover 2. The dust cover 2 can effectively block dust and impurities from entering the meshing area of ​​the drive gear 42 and the driven gear 43, ensuring that the two mesh normally. At the same time, it can also effectively block dust and impurities from falling into the circumferential side wall of the eccentric wheel 45 and the inside of the sleeve 46, thereby ensuring that the rotating eccentric wheel 45 can stably drive the main shaft 3 to make vertical reciprocating motion.
