Description

Technical Field

[0001] This application relates to the technical field of asphalt storage, and more specifically, to an asphalt storage tank. Background Art

[0002] In road construction, waterproofing projects, and many industrial fields, asphalt is an indispensable material. To ensure the construction progress and material quality, asphalt usually needs to be stored in a stable environment. At this time, the asphalt storage tank plays an important role.

[0003] Chinese Patent (Authorized Publication No. CN 219884705 U) discloses an asphalt storage tank, including a storage device and an automatic pressure relief mechanism. The automatic pressure relief mechanism is arranged on the storage device. The automatic pressure relief mechanism includes a pressure relief pipe for pressure relief and a limiting rod for limiting, and also includes a pressure plate for bearing pressure. When this asphalt storage tank is in use, when the pressure in the outer shell is relatively large, the pressure in the outer shell will push the pressure plate upward, causing the pressure plate to move upward until the pressure plate moves to the position of the pressure relief pipe, so that the gas can be discharged from the pressure relief pipe to achieve the function of automatic pressure relief. When the pressure relief is completed, through the downward elastic force of the elastic member on the pressure plate, the pressure plate returns to its original position.

[0004] Regarding the above related technologies, the inventor believes that in the existing technology, the air in the storage tank will only start to be discharged when the air pressure in the tank reaches a certain level. When adding asphalt, new air will be mixed in. During the whole process, the air is also in contact with the asphalt all the time. Long-term contact between the air and the asphalt will make the components in the asphalt vulnerable to the influence of oxidation reactions, forming colloidal substances, changing the molecular structure of the asphalt, cross-linking with each other, resulting in the hardening of the asphalt, enhanced brittleness, darkened color, and gradually losing its adhesive force and plasticity, which will greatly affect the use effect of the asphalt. Utility Model Content

[0005] In order to solve the above problems, this application provides an asphalt storage tank.

[0006] The asphalt storage tank provided by this application adopts the following technical solutions:

[0007] An asphalt storage tank includes a tank body. A rotating rod is rotatably connected inside the tank body. An activity cover plate is sleeved on the upper part of the rotating rod. The activity cover plate is in the shape of an umbrella surface, and several ventilation holes are opened at the top of the activity cover plate. Three thin film pieces are arranged in each ventilation hole. The lower end of the thin film piece is fixedly connected to the hole wall of the ventilation hole. The upper ends of the three thin film pieces protrude outward and are closely attached to each other. A feed inlet is opened at the lower part of the side wall of the tank body. A ring-shaped limiting ring is also fixedly connected to the lower part of the inner wall of the tank body. The limiting ring is arranged above the connection of the feed inlet.

[0008] Through the above technical solution, when injecting asphalt into the tank body through the feed port, the movable cover plate will float upward as the height of the asphalt liquid level rises. The air mixed with the newly added asphalt will slowly gather at the top of the movable cover plate and be discharged into the tank body through the air vent holes, while the air in the tank body will be discharged outward as the movable cover plate rises.

[0012] Through the above technical solution, the rotating rod drives the scraping paddle to rotate to scrape the asphalt material adhering to the side wall of the discharge bin, achieving a cleaning effect.

[0013] Preferably, an exhaust valve is installed on the upper surface of the tank body.

[0014] Through the above technical solution, the air accumulated in the tank body will be discharged through the exhaust valve.

[0015] Preferably, airtight rings are arranged on the side walls of the inner and outer circles of the movable cover plate.

[0016] Through the above technical solution, the airtight rings can ensure the airtightness during the up and down movement of the movable cover plate, preventing the air inside the tank body from re-entering below the movable cover plate.

[0017] Preferably, a motor is fixedly installed in the middle of the upper surface of the tank body, and the output end of the motor is in transmission connection with the rotating rod.

[0018] Through the above technical solution, the motor drives the rotating rod and then drives the scraping paddle to operate for scraping.

[0019] Preferably, the film sheet is made of elastic rubber material.

[0020] Through the above technical solution, the film sheet made of elastic material can maintain a state of protruding outward and closely fitting with each other under its own elastic force, ensuring that the gas can only pass unidirectionally, that is, flowing from under the movable cover plate to the upper side of the movable cover plate under the action of air pressure.

[0021] Preferably, a base is installed at the lower part of the tank body.

[0022] Through the above technical solution, the addition of the base can raise the tank body, which is convenient for discharging and can ensure the stability of the placement of the tank body.

[0034] Embodiment 1:

[0035] The following will further describe the present application in detail with reference to the Figures 1-3 accompanying drawings.

[0036] The embodiment of the present application discloses an asphalt storage tank. Please refer to Figure 1 , which includes a tank body 1. A rotating rod 2 is rotatably connected inside the tank body 1. An active cover plate 3 is sleeved on the upper part of the rotating rod 2. The active cover plate 3 is in the shape of an umbrella surface, and several ventilation holes 4 are provided at the top of the active cover plate 3. Three thin film pieces 401 are arranged in each ventilation hole 4. The lower ends of the thin film pieces 401 are fixedly connected to the hole walls of the ventilation holes 4. The upper ends of the three thin film pieces 401 protrude outward and are closely attached to each other. A feed inlet 5 is provided at the lower part of the side wall of the tank body 1. A ring-shaped limiting ring 6 is also fixedly connected to the lower part of the inner wall of the tank body 1. The limiting ring 6 is arranged above the connection of the feed inlet 5. By adding the active cover plate 3, when injecting asphalt into the tank body 1 through the feed inlet 5, the active cover plate 3 will directly separate the asphalt and the air in the tank completely. And the active cover plate 3 will float upward as the height of the asphalt liquid level rises. The air mixed with the newly added asphalt will also slowly gather at the top of the active cover plate 3 and be discharged into the tank body 1 through the ventilation holes 4, while the air in the tank body 1 will be discharged outward as the active cover plate 3 rises. During the process, the asphalt material is always isolated from the air, effectively avoiding the oxidation of the asphalt and ensuring the use effect. The addition of the limiting ring 6 can limit the movement range of the active cover plate 3 and prevent the active cover plate 3 from dropping too low and affecting the feeding of the feed inlet 5.

[0037] A funnel-shaped discharge bin 101 is provided at the lower portion of the tank body 1, a discharge port 102 is provided at the lower portion of the discharge bin 101, and a valve 103 is provided on the discharge port 102. The funnel-shaped discharge bin 101 can increase the speed of the asphalt material passing through the discharge port 102, which is convenient for rapid discharge, and the discharge process can be controlled accordingly through the valve 103.

[0038] A scraper paddle 7 is provided in the discharge bin 101, and the scraper paddle 7 is transmission-connected to the rotating rod 2. The rotating rod 2 drives the scraper paddle 7 to rotate to scrape off the asphalt material adhered to the side wall of the discharge bin 101 during discharging, thereby achieving a cleaning effect and avoiding long-term use of asphalt adhering to the side wall of the discharge bin 101 and causing equipment aging.

[0039] An exhaust valve 8 is installed on the upper surface of the tank body 1 , and the air accumulated in the tank body 1 will be discharged through the exhaust valve 8 as the movable cover plate 3 rises.

[0040] Airtight rings 301 are provided on the inner and outer side walls of the movable cover plate 3 . The addition of the airtight rings 301 can ensure the airtightness of the movable cover plate 3 during the upward and downward movement, and prevent the air inside the tank body 1 from re-entering below the movable cover plate 3 .

[0041] A motor 9 is fixedly installed in the middle of the upper surface of the tank body 1, and the output end of the motor 9 is transmission-connected with the rotating rod 2. The motor 9 drives the rotating rod 2 and then drives the scraper paddle 7 to operate for scraping.

[0042] The film sheet 401 is made of elastic rubber. The film sheet 401 made of elastic material can maintain a state of protruding outward and fitting closely to each other under the action of its own elastic force, ensuring that gas can only pass in one direction, that is, when the gas flows from the bottom of the movable cover to the upper side of the movable cover under the action of air pressure, the film sheet 401 will open upward. When the air pressure in the tank body 1 increases and the gas diffuses downward, the film sheet 401 will become tighter and tighter.

[0043] The implementation principle of an asphalt storage tank in an embodiment of the present application is as follows: During use, asphalt can be injected into the interior of the tank body 1 through the feed port 5 for storage. During this process, the movable cover plate 3 will directly separate the asphalt from the air inside the tank completely, and the movable cover plate 3 will float upward as the height of the asphalt liquid level rises. The air mixed with the newly added asphalt will also slowly gather at the top of the movable cover plate 3 and be discharged into the tank body 1 through the ventilation holes 4, while the air inside the tank body 1 will be discharged outward as the movable cover plate 3 rises. The film sheet 401 made of elastic material can maintain a state of protruding outward and being closely attached to each other under the action of its own elastic force, ensuring that gas can only pass unidirectionally. That is, when the gas flows from under the movable cover plate to the upper side of the movable cover plate under the action of air pressure, the film sheet 401 will open upward. When the air pressure in the tank body 1 increases and the gas diffuses downward, the film sheet 401 will tighten more and more, so that the asphalt material is always isolated from the air, effectively avoiding the oxidation of asphalt and ensuring the use effect. Subsequently, it can be discharged through the discharge port 102. The funnel-shaped discharge bin 101 can increase the speed of the asphalt material passing through the discharge port 102, facilitating rapid discharge. The valve 103 can control the discharge process accordingly. The scraping paddle 7 is driven by the rotating rod 2 to rotate to scrape off the asphalt material adhering to the side wall of the discharge bin 101 during discharge, achieving a cleaning effect and avoiding the aging of the equipment caused by the long-term adhesion of asphalt to the side wall of the discharge bin 101.

[0044] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
