Description

Technical Field

[0001] This utility model relates to the field of asphalt processing and application technology, and in particular to a bottom cone discharge structure for asphalt storage tanks. Background Technology

[0002] In the field of asphalt processing and application, asphalt storage tanks are core equipment used for the temporary storage and transfer of asphalt, and the rationality of their discharge structure directly affects the efficiency of asphalt production and turnover. At present, most mainstream asphalt storage tanks adopt a bottom discharge design. Among them, the bottom cone structure is widely used in various small and medium-sized asphalt storage scenarios, such as temporary storage for road construction and turnover of semi-finished products in asphalt processing plants, because it can utilize gravity to assist asphalt aggregation and reduce residue in the tank.

[0003] However, existing bottom-cone asphalt storage tanks still have significant technical problems in practical use: On the one hand, traditional discharge structures mostly rely on the natural discharge of asphalt by its own gravity. Due to the high viscosity of asphalt, discharge is prone to interruption and blockage in the tank, making it difficult to achieve continuous and uniform discharge. Especially in low-temperature environments, the fluidity of asphalt decreases, and the discharge efficiency is greatly reduced. On the other hand, when the storage tank needs to be relocated (such as for construction site relocation or equipment maintenance and relocation), the existing sealing structures are mostly manual plug-in type or simple cover type, which have poor sealing performance and are prone to asphalt leakage. This not only wastes raw materials but also pollutes the operating environment. Moreover, the manual operation process is cumbersome, increasing the labor intensity and safety risks of operators. Therefore, this utility model proposes a bottom-cone discharge structure for asphalt storage tanks. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a bottom cone discharge structure for asphalt storage tanks, so as to achieve continuous discharge of asphalt and reliable sealing when the position of the silo is changed.

[0005] To solve the above-mentioned technical problems, the present invention provides a bottom conical discharge structure for an asphalt storage tank, including a silo. The bottom of the silo is set in a conical structure, and a discharge mechanism is installed inside it to realize the continuous discharge operation of asphalt inside the silo. A sealing component is movably installed at the bottom port of the silo to seal the discharge port when the entire silo is repositioned.

[0006] The present invention is further configured such that handles are symmetrically and fixedly connected to the side walls of the hopper.

[0007] Through the above technical solution, the symmetrically arranged handles can serve as points for applying external force, making it convenient for operators to move and relocate the hopper by holding the handles, reducing the labor intensity when adjusting the position of the hopper. At the same time, the symmetrical structure ensures balanced force application, preventing the hopper from tilting or tipping over during movement, thus improving operational safety and convenience.

[0008] The present invention is further configured such that: the discharge mechanism includes rotating shafts rotatably connected to both sides of the hopper, and the rotating shafts are arranged symmetrically; discharge rollers are fixedly connected to the outer walls of both rotating shafts; multiple discharge plates are fixedly connected to the outer circumferential direction of the outer walls of both discharge rollers; gears are fixedly connected to the end faces of both rotating shafts; a drive motor is fixedly connected to the end face of one of the rotating shafts; and the drive motor is bolted to the side wall of the hopper.

[0009] Through the above technical solution, when the drive motor is working, the output torque drives the shaft connected to it to rotate. The shaft is driven by a gear fixed at the end face to mesh with a gear on another shaft, so that the two shafts rotate synchronously in opposite directions. When the shaft rotates, it drives the discharge roller fixed on the outer wall to rotate synchronously. Multiple discharge plates on the discharge roller move in a circular motion with the discharge roller. The discharge plates generate a pushing force on the asphalt at the bottom of the silo. In conjunction with the conical structure at the bottom of the silo, the asphalt moves along the conical cavity to the discharge port, thereby achieving continuous and uniform discharge and avoiding the accumulation and blockage of asphalt in the silo.

[0010] The present invention is further configured such that the two gears are meshed, and the diameter of the gears is larger than the diameter of the discharge roller.

[0011] Through the above technical solution, the meshing transmission of two gears can ensure the synchronous rotation and reverse motion relationship of the two rotating shafts, ensure the coordinated movement trajectory of the discharge plates on the two discharge rollers, avoid mutual interference, and form a synergistic pushing effect; the design of the gear diameter being larger than the discharge roller diameter can realize speed reduction and torque increase transmission. While keeping the output speed of the drive motor constant, it reduces the rotation speed of the discharge rollers and increases the torque of the discharge plate pushing the asphalt. This ensures a smooth and orderly discharge process and can also cope with the pushing resistance caused by the high viscosity of the asphalt, thus improving the reliability of discharge.

[0012] The present invention is further configured such that: the sealing assembly includes a sealing plate rotatably connected to one side of the bottom port of the silo; a fixing rod is fixedly connected to the rotation center of the sealing plate; a pushing plate is sleeved on the outer wall of the fixing rod; a guide rail is slidably connected to the end face of the pushing plate, and the guide rail is fixedly connected to the side wall of the silo; tension springs are symmetrically engaged on both sides of the end face of the pushing plate, and the other end of the tension spring is obliquely engaged to the side wall of the silo.

[0013] Through the above technical solution, the tension spring is always in a stretched state and applies an oblique pulling force to the push plate. Under the action of the pulling force, the push plate maintains a specific position along the guide rail. Through its sleeve engagement with the fixed rod, it generates a circumferential constraint force on the fixed rod, thereby driving the sealing plate to tightly fit against the bottom port of the hopper to achieve sealing. When discharge is required, the push plate can be driven by external force to overcome the tension of the tension spring and slide along the guide rail. The push plate drives the sealing plate to rotate around the rotation center through the fixed rod, so that the sealing plate separates from the discharge port of the hopper and releases the sealing state. When the position of the hopper is changed, the external force is removed, and the tension of the tension spring can drive the push plate to reset, thereby driving the sealing plate to close the discharge port of the hopper again, achieving automatic and reliable sealing.

[0014] The present invention is further configured such that: a movable groove is provided at the connection between the push plate and the fixed rod, and it is smoothly fitted to the outer wall of the fixed rod.

[0015] Through the above technical solution, the movable groove provides the fixed rod with a space for movement. Its smooth fit design with the outer wall of the fixed rod reduces the frictional resistance between the push plate and the fixed rod when the push plate slides, making the relative movement of the two smoother and avoiding the impact of friction jamming on the opening and closing action of the sealing plate. On the other hand, it ensures the effective constraint of the push plate on the fixed rod, ensuring that the linear motion of the push plate can be accurately converted into the circumferential rotation of the fixed rod, and realizing the precise opening and closing control of the sealing plate.

[0016] The present invention is further configured such that: a sliding groove is provided on the end face of the push plate away from the movable groove, and the push plate is slidably connected to the T-shaped guide rail through the sliding groove.

[0017] Through the above technical solution, the cooperation structure of the T-shaped guide rail and the slide groove plays a guiding and limiting role in the movement of the push plate, limiting the push plate to only move in a straight line along the length of the guide rail, and preventing it from deviating or falling off. The T-shaped structure design increases the contact area between the guide rail and the slide groove, improving the connection stability. At the same time, the sliding cooperation between the slide groove and the guide rail ensures the smoothness of the push plate's movement, providing structural support for the reliable operation of the sealing component.

[0018] The beneficial effects of this utility model are as follows: 1. The asphalt storage tank bottom cone discharge structure proposed in this utility model, by setting up a discharge mechanism consisting of a drive motor, double rotating shafts, discharge rollers and meshing gears inside the silo, combined with the cone structure at the bottom of the silo, can use mechanical pushing force to assist asphalt discharge, effectively solving the problems of easy blockage and discontinuous discharge in traditional gravity discharge, realizing uniform and stable asphalt discharge, and the gear reduction and torque increase design can be adapted to asphalt with different viscosities, thus improving the applicability of the structure; 2. The bottom cone discharge structure of the asphalt storage tank proposed in this utility model is equipped with a sealing assembly consisting of a sealing plate, a fixing rod, a push plate with a tension spring, and a T-shaped guide rail. The automatic reset characteristic of the tension spring is used to achieve reliable closure of the sealing plate, which not only ensures the sealing performance when the silo position is changed and avoids asphalt leakage, but also simplifies the opening and closing operation process and reduces the intensity of manual labor. At the same time, the symmetrical handle design on the side wall of the silo provides convenient force points for silo handling, further improving the ease of operation and practicality of the equipment.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] like Figures 1-4As shown, an asphalt storage tank bottom conical discharge structure includes a silo 1. Handles 11 are symmetrically fixedly connected to the side walls of the silo 1. These symmetrically arranged handles 11 serve as points for applying external force, facilitating the operator's handling and repositioning of the silo, reducing labor intensity during silo position adjustments. The symmetrical structure ensures balanced force application, preventing the silo from tilting or tipping over during movement, thus improving operational safety and convenience. The bottom of the silo 1 is conical, and a discharge mechanism 2 is installed inside to continuously discharge the asphalt from the silo 1. The discharge mechanism 2 includes rotating shafts 21 rotatably connected to both sides of the silo 1, with two symmetrically arranged shafts 21. Discharge rollers 22 are fixedly connected to the outer walls of both shafts 21, and multiple discharge rollers 22 are fixedly connected to the outer circumference of their respective outer walls. Each of the two shafts 21 has a discharge plate 23 and gears 24 fixedly connected to its end face. One shaft 21 has a drive motor 25 fixedly connected to its end face, and the drive motor 25 is bolted to the side wall of the silo 1. When the drive motor 25 is working, it outputs torque to drive the shaft 21 connected to it to rotate. The shaft 21 is driven by the gear 24 fixed to its end face to mesh with the gear 24 on the other shaft 21, so that the two shafts 21 rotate synchronously in opposite directions. When the shaft 21 rotates, it drives the discharge roller 22 fixed to the outer wall to rotate synchronously. The multiple discharge plates 23 on the discharge roller 22 move in a circular motion with the discharge roller 22. The discharge plates 23 push the asphalt at the bottom of the silo with the discharge plate 23. With the help of the conical structure at the bottom of the silo, the asphalt moves along the conical cavity to the discharge port, so as to achieve continuous and uniform discharge and avoid asphalt accumulation and blockage in the silo. Two gears 24 are meshed, and the diameter of gears 24 is larger than the diameter of the discharge roller 22. The meshing transmission of the two gears 24 can ensure the synchronous rotation and reverse motion relationship of the two rotating shafts 21, and ensure the coordinated movement trajectory of the discharge plates 23 on the two discharge rollers 22, avoiding mutual interference and forming a collaborative pushing effect. The design that the diameter of gears 24 is larger than the diameter of discharge rollers 22 can realize speed reduction and torque increase transmission. While keeping the output speed of drive motor 25 constant, the rotation speed of discharge rollers 22 is reduced, while the torque of discharge plates 23 pushing asphalt is increased. This ensures that the discharge process is smooth and orderly, and can also cope with the pushing resistance caused by the high viscosity of asphalt, thus improving the reliability of discharge.

[0023] like Figure 1 and Figure 4 As shown, a sealing component 3 is movably installed at the bottom port of the silo 1 to seal the discharge port when the entire silo 1 is repositioned. The sealing component 3 includes a sealing plate 31 rotatably connected to one side of the bottom port of the silo 1. A fixing rod 32 is fixedly connected at the rotation center of the sealing plate 31. A push plate 33 is sleeved on the outer wall of the fixing rod 32. A movable groove 331 is provided at the connection between the push plate 33 and the fixed rod 32, and it is smoothly fitted to the outer wall of the fixed rod 32. The movable groove 331 provides the fixed rod 32 with a space for movement. Its smooth fit design with the outer wall of the fixed rod 32 reduces the frictional resistance between the push plate 33 and the fixed rod 32 when they slide, making their relative movement smoother and avoiding the impact of friction jamming on the opening and closing action of the sealing plate 31. On the other hand, it ensures the effective constraint of the push plate 33 on the fixed rod 32, ensuring that the linear motion of the push plate 33 can be accurately converted into the circumferential rotation of the fixed rod 32, so as to achieve precise opening and closing control of the sealing plate 31. The end face of the push plate 33 away from the movable groove 331 is provided with a sliding groove 332, and is slidably connected to the T-shaped guide rail 34 through the sliding groove 332. The cooperation structure between the T-shaped guide rail 34 and the sliding groove 332 plays a guiding and limiting role in the movement of the push plate 33, limiting the push plate 33 to only move in a straight line along the length direction of the guide rail 34, and preventing it from deviating or falling off. The T-shaped structure design increases the contact area between the guide rail 34 and the sliding groove 332, improving the connection stability. At the same time, the sliding cooperation between the sliding groove 332 and the guide rail 34 ensures the smoothness of the movement of the push plate 33, providing structural support for the reliable operation of the sealing component 3. The end face of the push plate 33 is slidably connected to a guide rail 34, and the guide rail 34 is fixedly connected to the side wall of the hopper 1. Tension springs 35 are symmetrically engaged on both sides of the end face of the push plate 33, and the other end of each tension spring 35 is obliquely engaged to the side wall of the hopper 1. The tension springs 35 are always in a stretched state and apply an oblique pulling force to the push plate 33. Under the action of the pulling force, the push plate 33 maintains a specific position along the guide rail 34. Through its sleeve engagement with the fixed rod 32, it generates a circumferential constraint force on the fixed rod 32, thereby driving the sealing plate. 31 is tightly fitted to the bottom port of the hopper 1 to achieve sealing; when discharge is required, the push plate 33 can be driven by external force to overcome the tension of the tension spring 35 and slide along the guide rail 34. The push plate 33 drives the sealing plate 31 to rotate around the rotation center through the fixed rod 32, so that the sealing plate 31 is separated from the discharge port of the hopper 1 and the sealing state is released; when the position of the hopper 1 is changed, the external force is removed, and the tension of the tension spring 35 can drive the push plate 33 to reset, thereby driving the sealing plate 31 to close the discharge port of the hopper 1 again, so as to achieve automatic and reliable sealing.

[0024] When this utility model is in use, when material discharge is required, the drive motor 25 is started, and the drive motor 25 drives the corresponding rotating shaft 21 to rotate. Through the transmission of two meshing gears 24, the other rotating shaft 21 rotates synchronously in the opposite direction, and the two discharge rollers 22 rotate accordingly. The discharge plate 23 generates a pushing force on the asphalt in the hopper 1 and squeezes and opens the bottom sealing plate 31. With the help of the conical hopper bottom, continuous material discharge is achieved. When it is necessary to change the position, the discharge mechanism 2 is simply turned off. At this time, the sealing plate 31 uses the tension of two tension springs 35 to seal the bottom of the hopper 1 and prevent asphalt from falling.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
