Description
Technical Field
[0001] This invention relates to the field of anti-rutting agent storage tank technology, specifically an anti-rutting agent storage tank for asphalt road reconstruction. Background Technology
[0002] Asphalt is a dark brown, complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid, mostly existing in liquid or semi-solid petroleum form, with a black surface. It is soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementing material. Asphalt is used in asphalt road reconstruction. Anti-rutting agents are used in asphalt. Before use, anti-rutting agents are stored. This storage tank is used to store anti-rutting agents.
[0003] When storing anti-rutting agents, they are placed in storage tanks. However, due to the simple structure of the tanks, which store the anti-rutting agent in the tank cavity and allow material to enter and exit through the openings on the top of the tank, it is clearly impossible to meet the requirement of taking out a small quantity of anti-rutting agent material. At the same time, the position of the openings on the tanks is fixed. Usually, the tanks are supported by the ground or by a support frame structure. The entire structure of the tanks is fixed, which makes it inconvenient to discharge and store anti-rutting agent material. Multiple openings need to be set on the tanks, making the use of the tanks inconvenient. Summary of the Invention
[0004] The purpose of this invention is to provide a storage tank for anti-rutting agent in asphalt road reconstruction, to solve the problem mentioned in the background art. When storing anti-rutting agent, the agent is placed in a storage tank for storage. However, due to the simple structure of the tank, the anti-rutting agent is stored in the tank cavity, and the material enters and exits through the opening on the tank. This is clearly insufficient when a small quantity of anti-rutting agent needs to be removed. Furthermore, the opening on the tank is fixed in position, and the tank is usually supported by the ground or a support frame structure. The entire tank structure is fixed, making it inconvenient to discharge and store anti-rutting agent material, requiring multiple openings on the tank, and further complicating its use.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0027] Please see Figure 1-5 The present invention provides a technical solution: a storage tank for anti-rutting agent for asphalt road reconstruction, comprising a tank body 1, a support frame 3 at the lower end of the tank body 1, and a tank cavity 6 inside the tank body 1 for storing materials. Connecting shafts 2 are provided on both the left and right sides of the tank body 1 for rotatably connecting with the support frame 3. Rollers 4 are installed on the inner side of the support frame 3 near the end wall of the connecting shaft 2 for contacting the end wall of the tank body 1. The connecting shaft 2 is used to rotate the tank body 1 and switch the orientation of the seat screw 8 and the tank screw 9. Two sets of rollers 4 are provided, with two rollers in each set. The rollers 4 are rotatably connected to the support frame 3 and are used to rotate and support the tank body 1, making the tank body 1 more stable when rotating and assisting the tank body 1 in rotating.
[0028] A limiting screw 5 for tightening and limiting the tank body 1 is inserted through the end wall of the support frame 3 near the idler roller 4 and the connecting shaft 2. The support frame 3 is concave in shape, and the limiting screws 5 are symmetrically distributed about the center of the support frame 3. The limiting screws 5 and the support frame 3 are threaded together. In use, the tank body 1 can be rotated so that the seat screw 8 and the tank screw 9 face upwards. At this time, materials can be added to the seat screw 8 and the tank screw 9 respectively. Asphalt road reconstruction anti-rutting agent material is added to the seat screw 8 and stored through the tank cavity 6. Activated carbon granules are added to the tank screw 9 and stored through the seat cavity 11. The vent 12 allows for ventilation. The chamber 6 is dry and moisture-absorbing. After the seat screw port 8 and can screw port 9 are rotated to a position lower than the central axis of the connecting shaft 2, the seat screw port 8 is used to discharge the activated carbon particles that have absorbed moisture in the seat chamber 11, and the can screw port 9 is used to discharge the anti-rutting agent material stored in the can chamber 6. At the same time, since the can body 1 has the characteristic of free rotation, the height of the seat screw port 8 and can screw port 9 can be controlled and adjusted as the can body 1 rotates. When pouring materials, the lower the position of the seat screw port 8 and can screw port 9, the greater the pouring force. In addition, the pouring force can also be controlled and adjusted, making it more convenient to use and flexibly adapting to various discharge needs.
[0029] Outer seats 7 are provided opposite to each other on the left and right end walls of the tank body 1. A seat screw hole 8 is provided on the end wall of the outer seat 7, and a tank screw hole 9 is provided on the end wall of the tank body 1 for the material to enter and exit the tank cavity 6. The inner sides of the seat screw hole 8 and the tank screw hole 9 are threaded with sealing plugs 10 for sealing the seat screw hole 8 and the tank screw hole 9. A seat cavity 11 for storing materials is provided inside the outer seat 7. A vent hole 12 for ventilation is provided on the end wall of the seat cavity 11 of the outer seat 7 near the tank cavity 6. The outer seat 7 is annular in shape, while the tank body 1 is cylindrical. The tank cavity 6 of the tank body 1 is connected to the tank screw hole 9 and the tank cavity 6 is connected to the vent hole 12. The diameter of the vent hole 12 is smaller than the diameter of the material.
[0030] A guide plate 13 is provided near the end wall of the tank body 1 at the end of the screw port 9 to guide the material discharged from the screw port 9. The upper end wall of the guide plate 13 has a plate recess 14 for sliding the material. A plate groove 15, matching the shape and structure of the guide plate 13, is provided inside the bottom of the guide plate 13. An inner drawer 16 is movably installed within the plate groove 15. Screws 17 are inserted at both the front and rear end walls of the bottom of the guide plate 13. The screws 17 at the front end wall of the bottom of the guide plate 13 are used to limit the inner drawer 16 after displacement. The screw 17 at the rear end wall is used to assemble the guide plate 13 and the tank 1. The inner drawer 16 in the plate slide groove 15 extends out, extending the area for guiding materials formed by the guide plate 13 and the inner drawer 16. When discharging, unscrew the sealing plug 10 at the can screw port 9 and open the can screw port 9, so that the material is discharged from the can screw port 9. The material falls onto the guide plate 13 and is guided down by the guide plate 13. When in use, it is only necessary to set a receiving structure, such as a receiving dish, at the front end of the center of the support frame 3 to receive the material discharged from the guide plate 13, so as to achieve the effect of convenient material retrieval.
[0031] An opening 18 is provided on the left side of the tank body 1 near the end wall of the connecting shaft 2. A sealing plug 19 with a matching shape and structure is provided in the opening 18. A through-hole 20 is provided on the end wall of the tank body 1 near the center of the opening 18. A through-hole seat 21 is installed in the through-hole 20. A through-cavity 22 for storing materials is provided inside the through-hole seat 21. An inlet 23 communicating with the through-cavity 22 is provided on the end wall of the through-hole seat 21 near the can screw port 9. The opening 18 is located on the side wall of the tank body 1 near the can screw port 9. The opening 18, through-hole 20, and tank cavity 6 are arranged in sequence. Connect the plug 19 and screw it into the opening 18 to seal the through-hole 20. The two end walls of the through-hole 21 near the inlet 23 are inclined. The length of the through-hole 21 is greater than the length from the side wall of the tank cavity 6 to the inlet 23. When one end of the through-hole 21 is completely inserted into the tank cavity 6 and fits against the side wall of the tank cavity 6, the other end of the through-hole 21 still extends 3 cm into the opening 18. When retrieving the through-hole 21, the extra 3 cm makes it easy to manually pinch the end of the through-hole 21 and pull it out. In use, the through-hole 21 runs along the opening 18 and the through-hole opening. 22 is inserted into the can cavity 6. At this time, the can body 1 is rotated to the position where the seat screw 8 and can screw 9 are facing upwards. Then, tighten the limiting screw 5 to limit the can body 1, and screw the sealing plug 19 into the opening 18. After that, the material is put into the can cavity 6 along the can screw 9, and a part of the material falls into the cavity opening 22 along the inlet 23. The seat 21 is used to store a small amount of material in a quantitative manner. When it is necessary to take out a small portion of the material in a quantitative manner, first remove the sealing plug 19 at the opening 18, open the opening 18, and then pull out the seat 21 to achieve the quantitative removal of a small portion. The effect of the material, and the position of the opening 18, so that when the seat 21 is inserted into the opening 18, with the seat screw 8 and the can screw 9 facing upwards, the inlet 23 of the seat 21 faces upwards, and the seat 21 is close to the can screw 9. Therefore, when the seat 21 is pulled out, the material stored in the can cavity 6 will not leak out in large quantities from the opening 20. At the same time, the two end walls of the seat 21 near the inlet 23 are inclined, so that when the material is put in along the can screw 9, it can fall into the can cavity 6 better through the inclination of the seat 21, and will not accumulate in large quantities on the seat 21.
[0032] In summary, this storage tank for anti-rutting agent used in asphalt road reconstruction should be used as follows:
[0033] First, add activated carbon particles along the screw hole 8 into the seat cavity 11, then tighten the sealing plug 10 at the screw hole 8 to seal it, and let it breathe through the air hole 12 to dry the inside of the tank cavity 6, so that the tank cavity 6 creates a dry storage environment for storing anti-rutting agent for asphalt road reconstruction.
[0034] Next, insert the through seat 21 into the can cavity 6 along the opening 18 and the through hole 20, and make it close to the right side wall of the can cavity 6. Then screw on the sealing plug 19 to seal the opening 18.
[0035] At this time, rotate the tank body 1 through the connecting shaft 2 so that the seat screw 8 and the can screw 9 of the tank body 1 face directly upward, and then tighten the two limit screws 5 to limit the tank body 1;
[0036] Then, the anti-rutting agent material for asphalt road reconstruction is put into the tank cavity 6 along the screw opening 9, so that the tank cavity 6 stores the material. At the same time, a part of the material falls into the cavity opening 22 of the through seat 21 for storage, so that a small part of the material can be quantitatively taken out according to the needs later.
[0037] During material collection, either a fixed quantity of material can be collected or the discharge speed can be freely adjusted. For fixed quantity collection:
[0038] Rotate the sealing plug 19 to open the opening 18, and manually pinch one end of the seat 21 to pull out the seat 21 so as to conveniently remove the material in a quantitative manner for use or testing.
[0039] When freely adjusting the discharge speed for material handling:
[0040] Rotate the sealing plug 10 at the screw port 9 of the rotating tank to open the screw port 9. Then rotate the loosening limit screw 5 to put the tank body 1 in a free state. At this time, rotate the tank body 1 to change the height of the screw port 9. When the screw port 9 is in a lower position, the material is subjected to gravity and the discharge intensity is high. Conversely, the discharge intensity of the screw port 9 is low and the discharge speed is slow. Thus, the effect of freely adjusting the discharge speed is achieved. The discharged material is guided by the guide plate 13 so that the node into which the material is discharged is far away from the tank body 1. Thus, it is convenient for the receiving container to be far away from the tank body 1 and convenient for the receiving container to be placed.
[0041] Throughout the entire usage process:
[0042] The sealing plug 10 at the screw port 8 can be rotated to open the screw port 8, and then the activated carbon granules stored and used in the seat cavity 11 can be poured out along the screw port 8, making it convenient to replace the activated carbon granules and keep the can cavity 6 dry.
[0043] The inner drawer 16 slides within the groove 15 at the guide plate 13, causing it to extend outward. This alters the flow area formed by the inner drawer 16 and the guide plate 13, making it adjustable to accommodate different material receiving needs. For example, large receiving containers occupy a large area, and their center must be far from the tank 1. In this case, the flow area formed by the inner drawer 16 and the guide plate 13 is increased, directing the material towards the center of the container. Conversely, small containers will naturally have their center closer to the tank 1. At this time, the flow guiding area formed by the inner drawer 16 and the guide plate 13 is reduced, so that the material is discharged as much as possible to the center area of the container, and the material receiving adaptability is stronger. The screw 17 near the bottom front side of the guide plate 13 is tightened to limit the inner drawer 16 and the guide plate 13 after the flow guiding area is adjusted. The screw 17 on the bottom rear side of the guide plate 13 is used to disassemble and assemble the guide plate 13. After assembly, it is used for material discharge and flow guiding. After disassembly, it is used for cleaning the guide plate 13.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
